Abstract

This utility model relates to a belt conveyor with an anti-pinch roller. The main body is a belt conveyor, which includes a frame, a conveyor belt, and rollers rotatably mounted within the frame. One roller serves as the drive roller and is connected to a rotating motor. The conveyor belt covers all rollers, and transmission is achieved by the drive roller driving the conveyor belt. An auxiliary roller mounted on the frame is located in front of the conveyor belt. Rotary shafts are located at both ends of the auxiliary roller. V-shaped lifting components for accommodating the rotating shafts are fixedly connected to both sides of the frame, with the rotating shafts placed within the V-shaped lifting components. The V-shaped lifting component includes a front plate and a rear plate, with the front plate tilted forward. In the event of accidental hand contact and jamming between the auxiliary roller and the conveyor belt, this utility model applies a forward and upward force to the auxiliary roller during the squeezing process, guiding the auxiliary roller to rise under the guidance of the V-shaped lifting components. This increases the gap between the auxiliary roller and the conveyor belt, effectively preventing accidental hand injury.

Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a belt conveyor with an anti-pinch roller. Background Technology

[0002] In existing conveyor systems, one or two auxiliary rollers are typically mounted at the exit of the conveyor belt to assist material in smoothly leaving the belt. As the material exits the belt, its own potential energy drives the auxiliary rollers to rotate, effectively guiding the material into the next area. This design helps improve material flow and reduces material jamming or slippage.

[0003] However, with the widespread use and increasing complexity of production environments, existing designs present certain safety hazards. Especially in situations where workers need to retrieve materials from conveyor belts or auxiliary rollers, a small gap typically exists between the auxiliary roller and the conveyor belt. Workers often accidentally pull their hands into this gap upon contact with the belt. If a worker's hand gets caught in the gap, it can result in hand injuries or even more serious consequences. Such safety hazards not only pose a potential risk of injury to workers but can also lead to production stoppages and equipment damage, thereby affecting production efficiency and safety.

[0004] In the early design phase, the main consideration was to set up a pause button in this area. However, when a worker's hand is caught, it is difficult to react in time to touch the pause button, and each pause and restart will affect the transmission efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an anti-injury structure for the end roller of a conveyor, which can prevent accidental injury to human hands.

[0006] This utility model is achieved through the following technical solution: a belt conveyor with anti-pinch rollers, the main body of which is a belt conveyor, the belt conveyor including a frame, a conveyor belt and several rollers arranged in the front-back direction and rotatably installed in the frame;

[0007] One of the rollers serves as the drive roller and is connected to the rotating motor; the transmission belt covers all the rollers and is driven by the drive roller to achieve transmission.

[0008] An auxiliary roller mounted on the frame is provided in front of the transmission belt;

[0009] The auxiliary roller is provided with a rotating shaft at both ends. V-shaped lifting components for accommodating the rotating shaft are fixedly connected to both sides of the frame. The rotating shaft is placed inside the V-shaped lifting components.

[0010] The V-shaped lifting member includes a front plate and a rear plate, with the front plate tilted forward.

[0011] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0012] When a person accidentally touches and gets their hand stuck in the gap between the assist roller and the transmission belt, this invention can apply a forward and upward force to the assist roller during the squeezing process, causing the assist roller to be guided and lifted by the V-shaped lifting component. Then, the gap between the assist roller and the transmission belt increases, effectively preventing accidental injury to the person. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0014] Figure 2 A diagram illustrating the effect of the auxiliary lifting component engaging with the rotating shaft of the auxiliary roller;

[0015] Figure 3 The diagram shows the changes when a person inserts their hand into the gap between the auxiliary roller and the transmission belt.

[0016] Labeling: 1 Frame, 11 Conveyor belt, 12 Auxiliary roller, 13 Rotary shaft, 14 V-type lifting component, 142 Rear plate, 143 Front plate. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0018] like Figure 1 and Figure 2 As shown, a belt conveyor with anti-pinch rollers is a belt conveyor, which includes a frame 1, a conveyor belt 11, and several rollers arranged in the front-back direction and rotatably installed in the frame 1.

[0019] One of the rollers serves as the drive roller and is connected to the rotating motor; the transmission belt 11 covers all the rollers, and the drive roller drives the transmission belt 11 to achieve transmission.

[0020] An auxiliary roller 12 mounted on the frame 1 is provided in front of the transmission belt 11;

[0021] The auxiliary roller 12 is provided with a rotating shaft 13 at both ends. V-shaped lifting parts 14 for accommodating the rotating shaft 13 are fixedly connected to both sides of the frame 1. The rotating shaft 13 is placed into the V-shaped lifting parts 14.

[0022] The V-shaped lifting member 14 includes a front plate 143 and a rear plate 142, with the front plate 143 tilted forward.

[0023] This invention addresses the issue of accidental hand injury when a person's hand becomes stuck in the gap between the assist roller and the transmission belt. By applying a forward and upward force to the assist roller during the compression process, the V-shaped lifting member guides the roller upward, increasing the gap between the assist roller and the transmission belt and effectively preventing hand injury. The front plate 143 is tilted forward specifically to guide the assist roller. See details for further information. Figure 3 Furthermore, the auxiliary roller 12 can fall back to its original position due to its own weight after the hand is removed, preventing the gap between the auxiliary roller 12 and the conveyor belt 11 from being too large and thus failing to guide the transport of goods.

[0024] Furthermore, each of the rotating shafts 13 is equipped with a bearing, which is placed inside the V-shaped lifting member 14. With the bearing installed, the rotating shaft 13 does not need to directly contact the V-shaped lifting member 14, thus avoiding excessive frictional force on the rotating shaft 13 within the V-shaped lifting member 14.

[0025] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
