The existing chain has the following problems during use:

[0003] Currently, in the logistics transmission system, when using a chain to convey long cylindrical parts, a specific problem often occurs: during the conveying process on the surface of the chain, these parts tend to roll in the opposite direction of conveying due to uneven force or limitations of chain design. This unexpected rolling phenomenon not only seriously interferes with the smooth delivery of parts, but also may cause misalignment, accumulation, or even damage of parts on the transmission path, thereby affecting the efficiency and accuracy of the entire logistics transmission line. SUMMARY

[0005] To solve the problems of the prior art, the utility model aims to provide a chain for logistics transmission, which solves the problem of uneven force or limitations of chain design during the conveying process on the surface of the chain, which causes the parts to roll in the opposite direction of conveying. This unexpected rolling phenomenon not only seriously interferes with the smooth delivery of parts, but also may cause misalignment, accumulation, or even damage of parts on the transmission path, thereby affecting the efficiency and accuracy of the entire logistics transmission line.

[0006] (2) Technical solution

[0007] To solve the above technical problems, the utility model provides a chain for logistics transmission, which includes an inner chain plate, an outer chain plate, and a roller. Two inner chain plates are connected by a sleeve, the surface of the sleeve is sleeved with a roller, the inside of the sleeve penetrates a pin shaft, the two sides of the pin shaft are respectively connected with an outer chain plate, and the end of the outer chain plate penetrates an open pin;

[0008] The side surface of the outer chain plate is connected with a side lug, the side surface of the outer chain plate is connected with a vertical shaft, the surface of the vertical shaft is sleeved with a rotating cylinder, the surface of the rotating cylinder is provided with a limiting groove, the surface of the vertical shaft penetrating through the limiting groove is connected with a limiting block, the outer surface of the rotating cylinder is connected with a baffle, and the baffle is connected with the side lug through an arc spring.

[0009] When the chain is used, the elastic force of the arc spring extrudes the baffle, so that the baffle is in an open state, at this time, when the parts move in the opposite direction, the surface of the baffle close to the arc spring can be extruded, and under the limiting action of the limiting groove and the limiting block, the rotating cylinder cannot rotate counterclockwise, so the parts can be limited by the baffle.

[0010] Preferably, the rotating cylinder and the vertical shaft form a rotating structure, the rotating cylinder is connected with the limiting block through the limiting groove, and the baffle can drive the rotating cylinder to rotate on the surface of the vertical shaft when the baffle is extruded, and at the same time, the rotating cylinder drives the limiting groove to slide on the surface of the limiting block, and the rotating angle of the rotating cylinder on the vertical shaft can be limited by the limiting groove on the limiting block.

[0011] Further, the baffle and the arc spring form an elastic expansion structure, and the arc spring extrudes the baffle through its own elastic force, so that the baffle is in an open state.

[0012] Further, the inside of the roller is connected with a spring strip, the end of the spring strip is connected with a clamping block, the side surface of the clamping block is connected with a sliding block, the inner wall of the roller close to the sliding block is provided with a sliding groove, and the clamping block and the inner wall of the roller are provided with a ball.

[0013] Further, the recess of the clamping block is arc-shaped, the clamping block and the spring strip form an elastic expansion structure, and the clamping block can compress the spring strip when the clamping block is subjected to a force, and the spring strip can provide a counterforce through its own elastic force after being compressed.

[0014] Further, the sliding block and the sliding groove are symmetrically arranged on both sides of the clamping block, the sliding block and the roller form a sliding connection through the sliding groove, and the clamping block can drive the sliding block to slide in the sliding groove when the clamping block is subjected to a force, so that the movement direction of the clamping block can be limited.

[0015] (3) Advantageous effects

[0016] Compared with the prior art, the beneficial effects of the present application are as follows:

[0017] The elastic force of the arc spring extrudes the baffle, so that the baffle is in an open state, at this time, when the parts move in the opposite direction, the surface of the baffle close to the arc spring can be extruded, and under the limiting action of the limiting groove and the limiting block, the rotating cylinder cannot rotate counterclockwise, so the parts can be limited by the baffle, and the parts can be prevented from moving in the opposite direction on the surface of the chain, thereby improving the transmission efficiency and accuracy.

[0018] In this invention, the roller can contact the sleeve through the ball bearings. When the chain contacts the gear, it applies a force to the roller. When the roller is subjected to this force, it can move relative to the sleeve, thereby causing the ball bearings to move. The movement of the ball bearings exerts a force on the locking block, which in turn causes the spring strip to deform. After the spring strip deforms, it can provide a reaction force through its own elasticity for support. This avoids wear and chain damage caused by direct contact and rotation between the sleeve and the roller, thus improving the service life of the chain. Attached Figure Description
