Description

Technical Field

[0001] The invention relates to the technical field of paper bag production and processing, and in particular to a material collecting and waste rejecting device with automatic detection function and a control system thereof. Background Art

[0002] As we all know, paper is a recyclable resource. The raw material for papermaking is mainly plant fiber. In addition to the three main components of cellulose, hemicellulose and lignin, there are other components with lower content, such as resin and ash. In addition, there are auxiliary components such as sodium sulfate. In addition to plant fiber, different fillers need to be added to paper according to different paper materials. The commonly used plastic bags are made of polyethylene, and the raw material used is petroleum, which is already a scarce energy source for us. In contrast, the raw material for the production of paper bags is trees, which is a renewable resource.

[0003] One of the reasons why paper bags can be used instead of plastic bags is that they also have a certain carrying capacity. During the production process, the produced paper bags need to be packaged, but there is a lack of corresponding inspection process, resulting in a large number of defective products in the finished products. Generally, we can only check the pass rate through random inspection to adjust the machine, but we cannot solve the problem of defective products.

[0004] Therefore, it is necessary to invent a material collecting and waste rejecting device with automatic detection function and its control system to solve the above problems. Summary of the invention

[0006] The second object of the present invention is to provide a control system for a material receiving and waste rejecting device with an automatic detection function, so that the material receiving and waste rejecting device with an automatic detection function can realize automatic waste rejection.

[0007] In order to achieve the above-mentioned first purpose, the first technical solution of the present invention is: a material receiving and rejecting device with automatic detection function, including wall panels, a feeding mechanism, a material transfer mechanism and a bag receiving wheel are arranged between the wall panels on both sides, and a rejecting mechanism is also arranged on one side of the material transfer mechanism, the material transfer mechanism includes an upper material transfer device and a lower material transfer device, the upper material transfer device includes a main shaft, a conveying guide roller shaft and a sheet base belt, the main shaft and the conveying guide roller shaft are fixedly provided with a plurality of pulleys, the sheet base belt is sleeved on the pulley surface, the lower material transfer device includes a wide belt and a plurality of guide rollers, and the plurality of guide rollers are arranged in a triangular shape;

[0008] The waste rejection mechanism includes a waste rejection unit, a waste rejection wheel and a waste rejection belt. A support shaft is provided on one side of the conveying guide roller shaft, a bracket is fixedly connected between the support shaft and the conveying guide roller shaft, and the bracket is fixedly connected to the wall panel. A pressure roller fixed shaft and a pressure roller shaft are also provided on one side of the conveying guide roller shaft. Swing arms are rotatably connected to the pressure roller fixed shaft at both ends, a spring is fixedly connected to one side of the swing arm, and one end of the spring is fixedly connected to the wall panel. The pressure roller shaft is fixedly arranged between the swing arms, and the waste rejection wheel is arranged on one side of the conveying guide roller shaft, and the waste rejection wheel makes a circular motion around the conveying guide roller shaft. Pulleys are provided on the surfaces of the pressure roller shaft and the support shaft, and the waste rejection belt is sleeved on the surfaces of the pulley and the waste rejection wheel and is arranged in a triangular shape.

[0009] Preferably, the feeding mechanism comprises a conveyor belt, and a light source and a detection camera are provided at the top of the conveyor belt.

[0010] Preferably, the cross section of the swing arm is V-shaped.

[0011] Preferably, a connecting piece is provided between the waste rejection wheel and the conveying guide roller shaft, and the waste rejection wheel performs a circular motion around the conveying guide roller shaft via the connecting piece.

[0016] The technical effects and advantages of the present invention are as follows: a waste rejection function is added during the production process. When in use, when the paper bag is being conveyed by the conveyor belt of the feeding mechanism, after the detection camera captures the waste bag through the light source, an instruction is issued to control the execution of the waste rejection unit, and the waste rejection unit extends and pushes the waste rejection wheel. The waste rejection wheel makes a circular motion around the guide roller shaft and pulls the waste rejection belt. The waste rejection belt pulls the pressure roller shaft to make it make a circular motion around the fixed shaft of the pressure roller.
