Description

Technical Field

[0001] The utility model relates to a conveying machine, in particular to a safety protection device for preventing a production line from being rolled into a pipeline. Background Art

[0002] During production and assembly, in some assembly processes of the assembly line, personnel often stand on the conveyor belt to operate. Such conveyor belts usually run slowly, and cover plates are usually set at the driving end and the driven end of the conveyor belt. There is a gap between the cover plate and the end of the conveyor belt. This gap can easily cause objects or people to be caught inadvertently, especially feet, and work-related injuries such as foot pinching often occur.

[0003] The existing conveying equipment drive entrance is usually equipped with an anti-rolling device or a shooting switch to prevent accidents. However, when debugging this method, it is difficult to grasp the size and inconvenient to use. It only serves as a warning or causes work-related accidents when it fails.

[0004] A Chinese patent with announcement number CN201087007Y discloses a plate chain anti-rollback device. The magnetic switch is easily affected by factors such as temperature and on-site oil pollution environment during use. It has a high failure rate and is prone to errors during operation, which reduces the reliability of the entire device and affects the stability and continuity of the production line. Summary of the invention

[0005] The utility model aims to provide a safety protection device for preventing people or objects from being drawn into a conveying machine, which has a compact structure and is easy to debug, thereby ensuring the safe operation of the conveying machine and the safety of the operators.

[0006] To this end, the technical solution of the utility model is: a safety protection device for preventing rolling in of an assembly line, comprising a cover system and a conveying device, wherein the cover system and the conveying device are arranged relative to each other and form a movement gap; wherein the cover system is fixed to the facility through a bottom bracket; and the conveying device controls its movement state through a control system, and is characterized in that: an anti-pinch plate is arranged in the movement gap, and a sliding component is also arranged under the anti-pinch plate, and the sliding component is installed on a bracket under the cover system, wherein the sliding component also has a reset function;

[0007] A travel switch is also provided at the rear end of the sliding component. The travel switch is fixed to the lower part of the cover system through a travel switch bracket, and the travel switch is connected to the control system to form a loop.

[0008] The effect is:

[0009] In the present utility model, the anti-clamping plate forms displacement through the sliding component during the movement gap. When a human body or other object touches the anti-clamping plate, the tail of the sliding component slides to the travel switch and immediately stops the movement of the conveying device through the control system, playing a safety protection role. Conversely, the reset of the sliding component drives the anti-clamping plate to return, and the entire system resumes normal operation.

[0010] A further improvement lies in that: the structure of the anti-clamping plate is in a horizontal " " structure, the upper end of which is bent and flanged out through the movement gap and is flush with the plane of the cover plate system; the sliding component is installed at the lower part of the anti-clamping plate.

[0011] The effect is that:

[0012] The bent and flanged part at the upper end of the anti-clamping plate structure penetrates through the movement gap. Using its movement gap requires not much adjustment, and through its bent and flanged part, it can provide a blocking process for personnel or articles, etc., or increase the collision area of the anti-clamping plate, which is safe and reliable.

[0013] A further improvement lies in that: in the sliding component, the sliding shaft passes through the bracket. One end of the sliding component is connected to the anti-clamping plate through the first fixing bracket, and the other end is connected to the lower part of the cover plate system through the second fixing bracket; the travel switch is arranged at the tail end of the sliding component; a return spring is also sleeved on the sliding shaft between the first fixing bracket and the bracket.

[0014] The effect is that: the sliding shaft passes through the bracket, enabling the sliding shaft to form a movement relationship in the bracket, thereby providing a relative displacement space for the first fixing bracket and the anti-clamping plate; at the same time, the use of the return spring resets the first fixing bracket and the anti-clamping plate.

[0015] A further improvement lies in that: a linear bearing is also arranged between the sliding shaft and the bracket.

[0016] The effect is that: the linear bearing forms a smooth sliding relative to the bracket, and also provides a guarantee for the displacement and reset of the first fixing bracket and the anti-clamping plate.

[0017] A further improvement lies in that: a linear bearing is also arranged between the sliding shaft and the second fixing bracket, and a locking sleeve is arranged on the shaft diameter at the tail end of the sliding shaft and the sliding component.

[0018] The effect is that: the linear bearing forms a smooth sliding relative to the second fixing bracket, and at the same time, the setting of the locking sleeve adjusts the displacement distance of the entire sliding component.

[0019] A further improvement lies in that: the travel switch bracket is an adjustable bracket.

[0020] The effect is that: the adjustable bracket is adjusted under the cover plate system, and combined with the cooperation of the locking sleeve, it adjusts the displacement distance of the entire sliding component. Beneficial effects

[0021] In the utility model, the structure of the cover plate system and the conveying device remains unchanged. The anti-entrapment device is installed under the cover plate system, without redundant and complex settings, simple and practical, safe and convenient. Brief description of the drawings
