Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a belt-type material transmission device capable of preventing slipping. Background Art

[0002] There are mainly two working modes for the existing material conveying equipment: 1. The continuous transportation without stopping mode, which is mainly used for the transportation and handling of articles, with relatively low precision requirements; 2. The stepping mode, in which the conveying component takes a certain step length each time, and articles or products are usually accompanied by processing operations on the conveying component, with high requirements for the step length precision. Among them, for the existing belt-type material conveying device, a driving roller and a driven roller are arranged at the front and rear ends in the material conveying direction, and the conveyor belt body is stretched on the driving roller and the driven roller. However, the surfaces of both the driving roller and the driven roller are relatively smooth, and the conveyor belt body has a slipping phenomenon on the rollers (the driving roller and the driven roller). Especially for the stepping mode, the longer and faster the conveyor belt body is, the more difficult it is to ensure that each step length is consistent, resulting in poor precision in the front and rear directions (the material conveying direction) of the conveyor belt body and being difficult to meet the requirements of production and processing. Summary of the Utility Model

[0003] Aiming at the technical problem that the conveyor belt body of the existing belt-type material conveying device is prone to slip on the roller, the utility model provides a belt-type material transmission device capable of preventing slipping. A transmission toothed belt is arranged on the side of the conveyor belt body, and synchronous gears adapted to the transmission toothed belt are arranged at the corresponding ends of the driving roller body and the driven roller body, so as to realize synchronous transmission through the engagement of the teeth of the transmission toothed belt and the synchronous gears, avoid the slipping of the conveyor belt body, and meet the requirements of high-precision stepping feeding.

[0048] This embodiment further includes a tension adjusting assembly 600. The tension adjusting assembly 600 is connected between the air suction box body 100 and the driven roller body 300.

That is, the roller body of the supporting roller assembly 700 abuts against the lower side of the conveyor belt body 400 to support the conveyor belt body 400 below the air suction box body 100 through the supporting roller assembly 700, and to prevent the conveyor belt body 400 from flying away from the air suction box body 100 during high-speed operation.

[0051] Generally speaking, a plurality of supporting roller assemblies 700 are provided. The supporting roller assemblies 700 are arranged at intervals along the length direction of the air suction box body 100 to ensure that each section of the conveyor belt body 400 located below the air suction box body 100 is supported by the supporting roller assemblies 700.

[0052] On this basis, the present embodiment also includes a limit assembly 800, which is arranged on both sides of the length direction of the suction box 100. The limit assembly 800 is used to limit the lateral movement of the conveyor belt body 400, so as to assist the lateral movement of the conveyor belt body 400 through the limit assembly 800 to avoid the lateral deviation of the conveyor belt body 400.

[0054] It should be understood that the active roller body 200 and the driven roller body 300 are both of a smooth wall structure, so that the active roller body 200 and the driven roller body 300 do not cause damage to the conveyor belt body 400 due to adsorption.

[0055] In addition, the present embodiment is further provided with a driving assembly 900, which is in transmission connection with the active roller body 200, so as to drive the active roller body 200 and the synchronous gear 500 coaxially arranged therewith to rotate along their own axis, thereby driving the conveyor belt body 400 to move cyclically.

[0057] Thus, even when the conveyor belt body 400 is running at high speed, it will not slip relative to the driving roller body 200 and the driven roller body 300. When the driving roller body 200 stops, the conveyor belt body 400 will immediately stop moving. When the driving roller body 200 starts pneumatically, the conveyor belt body 400 will immediately start running, enabling the conveyor belt body 400 to start and stop at any time, achieving the effect of high-precision operation of the conveyor belt body 400 and meeting the requirements of high-precision step feeding.

[0058] Among them, a plurality of ventilation holes 110 are arrayed on the upper side surface of the air suction box body 100, and a plurality of adsorption holes 420 are arrayed in the middle of the conveyor belt body 400. When conveying materials, negative pressure can be provided to the air suction box body 100 to suck out the air between the materials and the conveyor belt body 400 through the ventilation holes 110 and the adsorption holes 420, and adsorb the materials on the conveyor belt body 400, avoiding relative movement between the materials and the conveyor belt body 400 when the conveyor belt body 400 conveys materials at high speed or step by step (there are working conditions of rapid start and rapid stop), and meeting the requirements of high-speed material conveying.

Moreover, the teeth of the transmission belt 410 on the conveyor belt body 400 are engaged with the synchronous gear 500, which can limit the conveyor belt body 400 and thus avoid lateral deviation of the conveyor belt body 400.
