The chain conveying belt has the advantages of being simple in structure and adjustable in width and facilitating width adjustment.

The present invention prevents a succeeding sheet from being caught in holes of preceding punched sheets.

The invention relates to a strawberry picking robot. The strawberry picking robot is designed for solving the technical problem of the existing like products that grabbing mode structures and structures of machine frames and the like are not good enough in design. A framework of the picking robot is a cubical aluminum-profile framework composed of aluminum profiles, a framework bottom plate of thealuminum-profile framework is provided with a traveling crawler, an actuating mechanism which separately drives three-dimensional traveling through an axial motor is arranged in the aluminum-profileframework, and a mechanical claw is arranged at the tail end of an X-axis direction of the actuating mechanism; a collet supporting seat is arranged at one end of an X-axis bottom plate of the actuating mechanism, a mechanical claw is arranged at the bottom of the collet supporting seat, a cutter blade is arranged at one end of a movable collet of the mechanical claw, the collet supporting seat atthe symmetrical opposite side of the movable collet is provided with a fixed collet, the other end of the movable collet is hinged to the collet supporting seat through a pin shaft and can swing, a camera and a sensor are arranged just above the mechanical claw, a collecting string bag or manipulator collection box is arranged just below the cutter blade of the mechanical claw, and a box groove of the manipulator collection box is driven through a rotating motor to achieve the opening and closing of a hinge mode.

The invention discloses a low-cost and high-quality warp-knitted unidirectional fabric and a production process thereof. A multiaxial warp knitting machine is adopted. The production process comprises the following steps that 1, weft yarns are laid, wherein the weft yarns are laid in a weft yarn laying zone of the multiaxial warp knitting machine, and it is ensured that the separation distances of the weft yarns are equal; 2, weft insertion and binding are performed, wherein the laid weft yarns are conveyed to a warp knitting machine head of the multiaxial warp knitting machine, are compounded with 0-degree warp yarns and then are bound by binding yarns, it is limited that one weft yarn is inserted every one rotating circle of the machine head and is bound. By adopting the process, the weft yarns equal in separating distance can be produced, the unidirectional fabric with the independently bound weft yarns has a flat cloth cover and is flat and straight, the weft yarns can be rough yarns of 200 tex and 300 tex, the raw materials are relatively lower in price, and the fabric cost is lower. In addition, fabric width adjustment is more convenient, waste is relatively little, the cost can be also controlled through device change, and the process is smooth and stable in operation.

The invention discloses a hydraulic crane for a middle trough. The hydraulic crane comprises frames, a crane jib, a crane jib liftingoil cylinder, a crane jib rotating oil cylinder and the like, wherein a supporting device is arranged on the two sides of each frame, a telescopic device is arranged between the frames on the two sides and comprises a frame telescopic cylinder at the bottom of the frame and a telescopic beam at the upper part of the frame. The hydraulic crane for the middle trough has the advantages that the horizontal size of the hydraulic crane for the middle trough is greatly reduced, so that the hydraulic crane for the middle trough can be conveniently transported on the ground and underground, the dismounting procedure is canceled, and the production efficiency is greatly improved. As a supporting structure is added, the stability of the crane is guaranteed when the middle trough is lifted; in addition, as the frame telescopic cylinder is connected with the frames through pin shafts, the frame telescopic cylinder is conveniently dismounted when the crane works, so that the workload is greatly reduced, and the efficiency is improved by several times.

The invention discloses a panel loading and unloading device for a plasma cutting machine. The panel loading and unloading device comprises a device body and an adjusting seat arranged on one side of the device body. The device body and the adjusting seat are mounted on the two sides of the top of the plasma cutting machine through screws correspondingly. The tops of the sides, close to each other, of the device body and the adjusting seat are connected with a supporting plate and an adjusting plate correspondingly. The supporting plate is of a cavity structure. The two sides of the supporting plate are provided with adjusting holes arranged linearly. The two sides, close to the supporting plate, of the adjusting plate are both provided with fixing grooves. The inner walls of the fixing grooves are fixedly connected with spring pillars. The ends, far from the adjusting plate, of the spring pillars are connected with adjusting levers. The bottom end of the supporting plate is provided with a sliding groove. A sliding rod is connected into the sliding groove in a sliding mode. The bottom end of the sliding rod is provided with a fixed plate. The panel loading and unloading device is reasonable in design and facilitates loading and unloading. The width of the whole device can be adjusted conveniently according to the width of a working table of the plasma cutting machine. The manual operation cost is reduced. The production efficiency of panels is effectively improved.
