Description

Technical Field

[0001] The utility model relates to the technical field of waste plastic collection, in particular to a waste plastic collection device. Background Technique

[0002] Waste plastics do not refer to waste, old and useless plastic products, but plastic products whose plastic material properties have not changed significantly after use. They can be recycled and reprocessed into new plastic products for reuse. During the process of recycling waste plastics, it is often necessary to first crush the waste plastics through a crusher, and at the same time collect the crushed plastics through a collection device for subsequent processing.

[0003] In the prior art, the crushed plastics are often collected through a collection cylinder. However, during the collection process, when a collection cylinder is full, the staff needs to manually control the discharge valve. If it is not closed in time, it is very likely that the plastics will spill onto the ground. Moreover, when a collection cylinder is full, it needs to be removed and then replaced with another empty collection cylinder, which is a waste of time in this process. Therefore, it is necessary to propose a waste plastic collection device to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a waste plastic collection device, which has the characteristics of automatically closing the solenoid valve when the collection cylinder is full to prevent the plastics from spilling out, and when collecting one collection cylinder, the full collection cylinder and the empty collection cylinder can be replaced to prepare for the next collection, thus reducing the waste of time.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A waste plastic collection device, including a bottom plate, a crushing box and two collection cylinders. Two crushing rollers are rotatably connected inside the crushing box. The lower end of the crushing box is penetrated and connected with a square pipe. A connecting frame is fixedly connected to the outer wall of the square pipe. A circular pipe is installed at the lower end of the connecting frame. A solenoid valve is arranged on the outer wall of the circular pipe;

[0006] Two vertical plates are fixedly connected to the upper end of the bottom plate. A lead screw is rotatably connected between the two vertical plates. The lead screw is driven by a first motor installed at the right end of the right vertical plate. A moving seat is threadedly connected to the outer wall of the lead screw. Two installation grooves are opened at the upper end of the moving seat. Pressure sensors are installed at the bottom sides of the inner walls of the two installation grooves. Pressure receiving plates are abutted against the upper ends of the two pressure sensors. The two collection cylinders are respectively placed on the upper ends of the two pressure receiving plates. A controller is installed at the right end of the right vertical plate.

[0007] For the convenience of respectively positioning the placement positions of the two collection cylinders, as an optimization of the waste plastic collection device of the present utility model, semi-circular positioning rings that fit the outer walls of the two collection cylinders are respectively fixedly connected to the upper ends of the two pressure-receiving plates.

[0008] For the convenience of improving the movement stability of the moving seat, as an optimization of the waste plastic collection device of the present utility model, the moving seat and the upper end of the bottom plate are slidably connected through sliders and chutes.

[0009] To prevent the two pressure-receiving plates from moving in the horizontal direction, as an optimization of the waste plastic collection device of the present utility model, the two pressure-receiving plates and the left and right sides of the inner walls of the two installation grooves are slidably connected through sliders and chutes.

[0010] To drive the rotation of the two crushing rollers, as an optimization of the waste plastic collection device of the present utility model, gears are fixedly connected to the rear sides of the two crushing rollers through connecting shafts penetrating the crushing box, the two gears are meshed with each other, an L-shaped frame is installed at the rear side of the crushing box, and the gear on the left side is driven by a second motor installed at the rear side of the L-shaped frame.

[0011] For the convenience of guiding the crushed material into the interior of the square pipe, as an optimization of the waste plastic collection device of the present utility model, a guiding square hopper is installed on the bottom side of the inner wall of the crushing box.

[0012] For the convenience of supporting and fixing the crushing box, as an optimization of the waste plastic collection device of the present utility model, an L-shaped fixing seat fixedly connected to the bottom plate is fixedly connected to the outer wall of the crushing box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The crushed plastic gradually enters the interior of the left collection cylinder and presses the left pressure sensor through the left pressure plate. When the plastic inside the left collection cylinder reaches a certain weight, the pressure sensor on the left at this time transmits the pressure signal to the controller, and the solenoid valve is automatically closed through the controller, thereby achieving the purpose of preventing the plastic from spilling. At the same time, the first motor is controlled by the controller to operate, so that the right collection cylinder is located directly below the round tube, and the solenoid valve automatically opens, so that the right collection cylinder can be collected. While collecting, the collected left collection cylinder can be removed, and the empty collection cylinder can be placed in this position. After the right collection cylinder is collected, the solenoid valve automatically closes, and the first motor rotates in the reverse direction, so that the empty collection cylinder can be moved directly below the round tube, and the solenoid valve automatically opens, so that the empty collection cylinder can be collected, thereby achieving the purpose of replacing the collected collection cylinder and the empty collection cylinder while collecting one collection cylinder, for the next collection, thereby reducing time waste.
