Description

Technical Field

[0001] This utility model relates to the field of industrial processing technology, specifically to a conveying device for plastic processing. Background Technology

[0002] Plastic granules refer to granular plastics, generally classified into more than 200 types, with further subdivisions reaching thousands. Common types of plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. In industrial production, plastic granules are required for processing. Before processing, the plastic granules need to be transported to the processing location using conveyor equipment.

[0003] The existing patent (publication number: CN212638986U) discloses a method that uses a motor to drive gears installed at both ends of a connecting shaft. These gears drive a gear rack, enabling the conveyor belt to move at a uniform and stable speed, thus improving the stability of the device during the transport of plastic granules. Pulleys are installed on the outer side of the drive shaft installed on one side of the motor and at one end of the rotating shaft. Through belt drive, the motor simultaneously drives the belt to rotate the rotating shaft. A spiral plate is installed on the outer surface of the rotating shaft. When plastic granules are placed into the hopper, the rotation of the spiral plate spreads the granules evenly between the guide strips, preventing granule accumulation and affecting the transport efficiency, thus improving the device's working efficiency. A baffle is installed on one side of the hopper to prevent granules from popping out during transport, reducing waste. A hydraulic rod and hydraulic cylinder are installed below the side plate to adjust the conveyor belt's transport height, improving the device's adaptability to different equipment.

[0004] However, the aforementioned equipment still has certain shortcomings. During the production and processing of plastic granules, plastic granules with different properties often exhibit different plasticity. In the actual conveying process, some plastic granules or dust often remain on the conveyor belt. When conveying plastic granules with different plasticity, the residual plastic granules or dust are easily mixed with the newly conveyed plastic granules. This mixing will greatly reduce the purity of the subsequent plastics of different plasticity. In subsequent processing, the purity of the plastic will be affected, which will inevitably have many adverse effects on the processing quality. It may lead to unstable physical properties of the product, appearance defects, and affect the overall performance indicators of the product. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a conveying device for plastic processing to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for plastic processing, comprising a base plate, wherein a conveyor belt body is mounted on the upper surface of the base plate, and a cleaning component is fixedly mounted on the lower surface of the conveyor belt body by bolts;

[0007] The cleaning assembly includes a first cover plate and a second cover plate fixedly mounted to the lower surface of the conveyor belt body by bolts. A brush roller is rotatably connected inside the first cover plate. A first motor is fixedly mounted on one outer wall of the first cover plate, and the output end of the first motor passes through the first cover plate and is connected to the rotating shaft of the brush roller. A connecting pipe is fixedly mounted on one inner wall of the first cover plate. Two sets of water-absorbing rollers are rotatably connected to the inner wall of the first cover plate away from the brush roller. A conical bucket is fixedly mounted on the lower surface of the first cover plate by bolts. A slot is opened in the inner wall of the conical bucket, and a suction screen is inserted into the inner wall of the slot. Two sets of air knives are rotatably connected inside the second cover plate.

[0008] The conveyor belt body is started by operating the control panel, and then the booster water pump is started to draw water from the filter device and fill the manifold through the water inlet pipe. Multiple sets of nozzles wash the surface of the conveyor belt body, and the first motor is started to drive the brush roller to brush and wash to remove residual plastic particles or powder to ensure the purity of subsequent plastic particles. Wastewater and impurities enter the cone hopper, and the wastewater is discharged into the prefabricated water tank. Impurities are intercepted by the suction screen. After the filter device filters the wastewater, it is circulated through the booster water pump and the water inlet pipe to save water. When the brush roller rotates, the first sprocket and the second sprocket drive the water suction roller to roll against the outer wall of the conveyor belt body to achieve preliminary dehydration. Finally, the air knife is aimed at the conveyor belt body to air dry before it is put into use.

[0009] Furthermore, a baffle is fixedly connected to the inner wall of the first cover plate, a first sprocket is fixedly sleeved on the outer wall of the shaft at the end of the brush roller away from the first motor, and a second sprocket is fixedly sleeved on the outer wall of the central shaft at both ends of the water absorption roller.

[0010] By adopting the above technical solution, the baffle can isolate the brush roller and the water absorption roller, preventing the water absorption roller from being contaminated during the brush roller cleaning process.

[0011] Furthermore, the outer walls of the first and second sprockets on one side are connected by chain drive, and the two sets of second sprockets are connected by chain drive.

[0012] By adopting the above technical solution, two sets of water-absorbing rollers and brush rollers can be connected by a chain, and the first sprocket is half the size of the second sprocket, so as to realize the slow rotation of the water-absorbing rollers, reduce wear, and ensure the water absorption effect.

[0013] Furthermore, the outer wall of the connecting pipe is connected to multiple sets of nozzles, the outer wall of the connecting pipe is connected to a water inlet pipe, the top of the cone is connected to the inside of the first cover plate, the outer wall of the suction net is fixed to the cone by multiple sets of bolts, and the lower surface of the cone is connected to a drain pipe.

[0014] By adopting the above technical solution, one end of the water inlet pipe is connected to the output end of the booster pump, and the input end of the booster pump is connected to the filter device. One end of the drain pipe is connected to the external water tank, and the filter device is connected to the external water tank through the connecting pipe, thereby realizing the recycling of water resources and reducing water costs.

[0015] Furthermore, a slot is provided in the middle of the second cover plate, a second motor is fixedly installed on the outer wall of the second cover plate, and a worm gear is rotatably connected to the outer wall of the second cover plate, with one end of the worm gear connected to the output end of the second motor.

[0016] By adopting the above technical solution, the grooving can avoid collision with the hydraulic cylinder when the conveyor belt body is adjusted. The second motor can drive the worm, and the worm can mesh with two sets of worm wheels to adjust the direction of the two sets of air knives, thereby adjusting the distance between the air outlet and the conveyor belt body and thus controlling the drying rate.

[0017] Furthermore, a worm gear is fixedly sleeved on the outer wall of the rotating shaft at one end of the air knife, and the worm meshes with two sets of worm gears.

[0018] By adopting the above technical solution, the meshing of the worm gear and worm can use its own self-locking characteristics to limit the two sets of air knives, preventing them from rotating due to the reaction force generated by high wind speed during use.

[0019] Furthermore, a filter device is fixedly installed on the upper surface of the base plate, a booster water pump is connected to the outer wall of the filter device, the drain pipe is connected to the filter device, one end of the inlet pipe is connected to the booster water pump, a control panel is fixedly connected to one side of the outer wall of the base plate, and the control panel is connected to the booster water pump, the first motor, and the second motor through wires.

[0020] By adopting the above technical solution, the control panel can connect the various components of the device through circuitry, making it easier for operators to quickly control the device and perform related operations.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention starts the conveyor belt body via the control panel, then activates the booster water pump to draw water from the filter device, which then fills the manifold through the inlet pipe. Multiple spray nozzles wash the surface of the conveyor belt body while the first motor drives the brush roller to remove residual plastic particles or powder, ensuring the purity of the plastic particles in the subsequent washing process. Wastewater and impurities enter the cone hopper, and the wastewater is discharged into the prefabricated water tank. Impurities are intercepted by the suction screen. After the filter device filters the wastewater, it is circulated through the booster water pump and the inlet pipe to save water. When the brush roller rotates, the first and second sprockets drive the water suction roller to roll against the outer wall of the conveyor belt body through chain drive to achieve initial dehydration. Finally, the air knife is used to air dry the conveyor belt body before it is put into use. Attached Figure Description
