And a plurality of groups of anti-falling covers are uniformly arranged at the bottom ends of the mesh belt module and the edge section module. By arranging the anti-falling cover, the anti-falling cover can be located below the pin roller, when the pin roller is impacted and the whole limiting structure elastically deforms instantly, the anti-falling cover can play a role in auxiliary supporting, and meanwhile when the pin roller is impacted violently and the structure falls off, the anti-falling cover can effectively intercept the failed pin roller and prevent the failed pin roller from falling into a rack, so that the service life of the pin roller is prolonged, and the service life of the pin roller is prolonged. And in addition, the anti-falling cover of the cross-shaped structure facilitates faster discharging of foreign matters such as chippings and dust, and the situation that operation of the pin rollers is affected is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of plastic conveyor belt modules, in particular to a plastic conveyor belt module with a roller anti-drop cover. Background Art

[0002] Roller attachment type modular plastic mesh belts are widely used in express delivery, tire production and other industries to smoothly transport goods to designated processing stations. The plastic modular mesh belt requires each module to be staggered and spliced ​​according to a certain pattern, and then the pins are inserted into the pin holes at both ends of the modules to combine the modules connected together into a ring conveyor belt.

[0003] Since the mainstream use environment of this mesh belt is relatively complex, there will be more heavy and special-shaped items when transporting goods, and there may be a certain height difference at the equipment docking point. The modular plastic conveyor belt must have high strength to prevent the rollers from falling and meet the needs of long-distance transportation.

[0004] During the operation of the mesh belt, the rollers are easily impacted by the goods and the sprockets may run off course and hit the rollers, causing the rollers to fall into the frame under force, causing adverse problems. In addition, with the increase in speed and length of the line, the existing sprocket meshing structure is too thin, affecting its service life, and the traditional pin plug cannot be disassembled and is easy to fall off. Utility Model Content

[0005] The main purpose of the utility model is to provide a plastic conveyor belt module with a roller anti-drop cover.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0008] Preferably, the mesh belt module and the side segment module are provided with mounting grooves, and the mounting grooves are located on one side of the waist hole.

[0009] Preferably, mounting holes are arranged on the surrounding walls of the mounting groove, and rollers are rotated between the symmetrical mounting holes.

[0010] Preferably, the anti-detachment cover is located at the bottom end of the mounting groove, and the anti-detachment cover corresponds to the position of the roller, and the arc groove at the top end of the anti-detachment cover is adapted to the roller.

[0011] Preferably, a plug is installed at one end of the edge section module, the plug is rotatably connected to the edge section module, and a waist groove is provided in the middle of the plug.

[0012] Preferably, a boss is installed on one side of the plug, and an empty groove is opened on the edge section module corresponding to the boss.

[0013] Preferably, the tensioning fixture comprises a back plate, a plug and a support plate, wherein the back plate is connected to the waist hole through the plug, and the support plate is connected to the back plate through bolts.

[0014] The beneficial technical effects are:

[0015] 1. By setting the anti-drop cover, the anti-drop cover can be located under the roller. When the roller is impacted and the entire limit structure undergoes instantaneous elastic deformation, the anti-drop cover can play an auxiliary support role. At the same time, when the roller is hit violently and the structure falls off, the anti-drop cover can effectively intercept the failed roller to prevent it from falling into the frame and affecting the running stability. The cross-shaped anti-drop cover facilitates faster discharge of foreign matter such as debris and dust to avoid affecting the operation of the roller.

[0016] 2. The chain teeth with an angled structure can allow the sprocket to smoothly enter the tooth groove through the angle of inclination after the chain belt expands and contracts, completing automatic deviation correction, making the sprocket and chain belt run more smoothly;
