The invention relates to a vegetable seedling raising device, in particular to a vegetable seedling raising device that can automatically and accurately and quantitatively plant. Technical problem: to provide a vegetable seedling raising device with high work efficiency, which can automatically and accurately control the accurate depth of the nutrient pressure pit and accurately and quantitatively plant. The technical solution is as follows: a vegetable seedling raising device that can automatically and accurately and quantitatively plant seeds, including a support frame and the like; the support frame includes a front support, a rear support, a first support, a second support, a third support and a horizontal connecting plate. The brackets and the rear brackets are symmetrically arranged in the front and rear, the first bracket, the second bracket, the third bracket and the horizontal connecting plate are all arranged in two, the lower ends of the two first brackets are respectively fixedly connected to the upper outer sides of the front bracket and the rear bracket, and the two The lower ends of the second brackets are respectively fixed and connected to the upper outer sides of the front bracket and the rear bracket. The present invention achieves the effect that the present invention realizes accurate and quantitative sprinkling of vegetable seeds in the seedling tray through the pressing mechanism, the pressing hole mechanism and the seeding mechanism.

The invention relates to a barcode printer with an online cutting function, comprising a bracket, a driving mechanism, a printing mechanism and a cutting mechanism, the driving mechanism, the printing mechanism and the cutting mechanism are all arranged on the bracket, the printing mechanism includes a printing component and a limit component, the cutting The mechanism includes a moving component and a cutting component, and the driving mechanism includes a driving component and a linkage component. The barcode printer with online cutting function drives the printing mechanism and the cutting mechanism to run intermittently through the driving mechanism, so as to realize the intermittent transmission and cutting of paper sheets. Through the main body To achieve printing, the device realizes the operation of the printing mechanism and the cutting mechanism through one output end, which saves energy. At the same time, it adopts linkage to realize online cutting of printing paper, and the linkage adopts a purely mechanical structure, which improves the stability and stability of the device. Compared with the existing cutting mechanism, the mechanism can realize the disassembly and assembly of the blade by simple pressing, and the operation is simple and convenient.

The invention relates to the technical field of functional food detection, and provides a safety detection device for functional food processing and an operation method thereof, aiming at solving the problems of unreasonable structural design, long detection time and slow speed in the use process of the existing food safety detection device. , lack of accuracy and other drawbacks, all make the safety detection of functional foods defective, including the bar-shaped case with the upper end not closed and a plurality of feet installed at the lower end of the bar-shaped case, the upper part of the inner cavity of the bar-shaped case is installed horizontally There is a transmission mechanism, and the upper end of the bar-shaped case is provided with a detection box shell, an infrared spectrometer is installed on the inner top wall of the detection box shell on the side near the input end of the transmission mechanism, and a detection mechanism is arranged in the detection box shell; the transmission mechanism It includes a transmission chain plate belt horizontally arranged on the upper part of the inner cavity of the bar-shaped chassis. The invention is especially suitable for automatic and intelligent detection of functional food, has high detection accuracy, and has high social use value and application prospect.

The invention relates to the technical field of weaving, and especially relates to a device used for weaving. The device comprises a transmission table, a transmission roller used to transmit a clothon the transmission table, and a wind-up roller used to wind up the cloth. The wind-up roller is on a discharge end of the transmission table. The transmission roller comprises a roller body, a pressing column, and a smoothing platform. The roller body is internally provided with a steam channel. The roller body is provided with an air outlet hole and a sliding hole. The sliding hole is internallyslidably connected with a sliding rod. The sliding rod is fixedly connected with the smoothing platform. A spring is arranged between the smoothing platform and the roller body. The pressing column is used to insert into the steam channel and control sliding of the sliding rod. The pressing column is provided with a blocking column used to block the air outlet hole. An end of the transmission roller is rotatably connected with a steam pipe. One end of the pressing column, close to the steam pipe, can contact with an orifice of the steam pipe. The transmission roller is also provided with a positioning portion used to fix the pressing column in the steam channel. The pressing column, the sliding rod, and the smoothing platform are made of a heat conduction material. The scheme can eliminate folds on a surface of the cloth.

The invention discloses a feeding device for a punch. The feeding device comprises a frame fixed to a worktable. A first compression roller and a second compression roller, which abut against the upper and lower surfaces of a steel strip, respectively, are rotatably connected to the frame. A ratchet wheel is fixed to an end portion of the first compression roller. A drive sleeve is rotatably connected to the first compression roller. A ratchet is hinged to the inner wall of the drive sleeve, and the ratchet is connected to the drive sleeve by means of a first elastic part. A first connecting rod is fixed to an outer wall of the drive sleeve. A second connecting rod is hinged to the first connecting rod. One end, far away from the first connecting rod, of the second connecting rod is hinged to a flywheel. Thus, the purpose of improving the production efficiency is achieved.

The invention relates to the technical field of daily necessities, and discloses a spherical general merchandise vending device that automatically replenishes goods according to the placement of goods, including a shell, the inside of which is movably connected with a first turntable; The clamping rod is far away from the ratchet, so that after the goods are removed, the operation of the automatic start-up equipment turns and the turn plate rotates to make the transfer plate rotate 90 degrees intermittently. With the help of the gravity of the goods, it automatically falls and the goods are transported to realize the intermittent transmission of the goods. Automatically To replenish the goods, the rotation of the first turntable makes the block move up and down, causing the first rotating rod to approach each other to limit the position of the goods and move the placement table to the highest position, automatically adjust the position of the goods, avoid the position too far, and reduce the goods The display is beautiful, and the goods are automatically fixed to prevent the goods from moving, so that they are located at the pick-up port for easy access, and avoid placing too many goods at the same time and causing confusion.
