The invention provides an automatic packaging machine, which is usually applied to an automatic production line. The automatic packaging machine includes a plurality of hoppers, a horizontal transmission mechanism, a lifting transmission mechanism, and a packaging machine, wherein the lifting transmission mechanism includes a pair of lifting guide rails, a pair of arc-shaped guide rails, a first linear transmission mechanism and a second linear transmission mechanism. transmission mechanism. The first linear transmission mechanism is arranged along the lifting guide rail, and it is fixedly provided with a plurality of lifting levers, and the lifting lever contacts the support shaft of the hopper to drive the hopper to move along the lifting guide rail and the arc guide rail; the second linear transmission mechanism and the first The linear transmission mechanisms are arranged adjacent to each other with a certain angle between them, and a plurality of limit levers are arranged on them, and when the hopper moves along the arc guide rail, the limit levers abut against the support shaft to limit the hopper to slide down. In this way, the position limit of the hopper is realized, and the hopper is prevented from sliding down from the arc guide rail due to gravity when the arc guide rail is flipped and unloaded, thereby improving the production efficiency of the packaging machine.

The invention discloses a gas water heater, a wind pressure detection method and a fan control method. The gas water heater includes a fan motor, and the gas water heater further includes a wind pressure detection device and a double-layer smoke pipe including an inner layer smoke pipe and an outer layer smoke pipe. One end of the layer smoke pipe is connected to the gas collecting hood, and the other end leads to the outdoor. The inner layer smoke pipe is used to discharge the flue gas in the gas collecting hood to the outdoor; The wind pressure detection equipment detects the wind pressure difference between the two ends of the outer smoke pipe, and the wind pressure difference is used to adjust the operation of the fan motor. On the one hand, the present invention can detect the indoor and outdoor wind pressure difference in time before the gas water heater is started, avoids the delay of the wind pressure difference detection, and further facilitates the subsequent timely compensation of the fan current according to the wind pressure difference to control the operation of the fan. On the other hand, it can also prevent the ignition flame from overflowing under the anti-wind pressure, and at the same time, because of the real-time detection of the wind pressure difference, a rapid response to the anti-wind pressure can be achieved.

The invention discloses a potting tool for a round printed part shell and a clamping method of the round printed part shell. The potting tool comprises a base, a horizontal handle, a horizontal pressing block, a vertical handle and an arc-shaped pressing block; the base is horizontal, the upper surface of the base is provided with a guide rail, and the two ends of the base are vertically providedwith a front baffle and a rear baffle in an extension mode correspondingly; the horizontal handle is arranged on the outer side of the base, the horizontal handle is connected to one end of a feedingshaft, the feeding shaft penetrates through the front baffle, the feeding shaft is in threaded connection with the front baffle, the other end of the feeding shaft extends into a blind hole in one side of the horizontal pressing block, and the bottom of the horizontal pressing block is in sliding connection with the guide rail; and a guide block extending towards the inner side of the rear baffleis arranged at the top of the rear baffle, a vertical threaded through hole is formed in the extending part, the vertical handle is arranged above the guide block, the bottom of the vertical handle isconnected to a threaded shaft penetrating through the threaded through hole, the other end of the threaded shaft extends into a blind hole in the top of the arc-shaped pressing block, the threaded shaft is in interference fit with the blind hole in the top of the arc-shaped pressing block, and the radius of the arc-shaped pressing block is the same as the radius of the shell. A potting glue can be smoothly injected into the shell so that potting holes can be quickly and effectively sealed.

The invention discloses a vehicle-mounted waste storage device which comprises a supporting bottom plate, a waste bin body fixedly connected in the center of the upper end of the supporting bottom plate, two guide posts arranged on the two sides of the waste bin body, and a cross beam fixedly connected between the upper ends of the guide posts, wherein the lower ends of the two guide posts are fixedly connected with the supporting bottom plate; a partition plate is arranged at the upper part of the waste bin body; two guide holes are formed in the positions, corresponding to the two guide posts, of the partition plate; the partition plate is slidingly arranged on the outer sides of the two guide posts through the two guide holes in a sleeving manner; the parts, above the partition plate, of the two guide posts are respectively sleeved with two springs; the two ends of the springs respectively push against the cross beam and the partition plate; an annular locating sleeve is fixedly connected with the position, corresponding to an upper opening end of the waste bin body, of the lower part of the partition plate; and the locating sleeve is matched with the outer side of the upper opening end of the waste bin body in a sleeving manner. The device is reasonable in structure, can effectively store waste, and can avoid waste overspill in a bumping process.
