Description

Technical Field

[0001] This utility model relates to the field of engineering plastics processing, and in particular to a cutting device for processing engineering plastics. Background Technology

[0002] A search of Chinese patents revealed publication number CN208896180U, which describes an engineering plastic cutting device. The device includes a frame, a cutting chamber, a clamping plate, a cutting opening, a screw, a transmission pulley, a drive motor, a transmission wheel, a moving block, a fixed bearing, a transmission shaft, a transmission motor, a circular saw blade, a dust collection box, a dust suction pipe, a dust suction hood, and an exhaust fan. The cutting chamber is located at the top of the frame and has an inlet and an outlet. The clamping plate is located inside the inlet. The cutting opening is located above the cutting chamber, and the screw is located on the left and right sides of the cutting chamber. On both outer sides, the drive pulley is movably connected to the lower end of the screw. The drive pulley is connected to the output shaft of the drive motor. The drive pulley is connected to the drive pulley via a drive belt. The moving block is threaded onto the screw. The fixed bearing is located on the top of the moving block. The drive shaft is located between the two fixed bearings. The drive motor is connected to the drive shaft. The dust collection box is connected to the outside of the dividing compartment. One end of the dust collection pipe is connected to the dust collection box. The dust collection hood is connected to the other end of the dust collection pipe. The dust collection hood is connected to the inside of the dividing compartment. The exhaust fan is located inside the dust collection pipe.

[0003] Existing cutting equipment is not suitable for fixed-length cutting. Generally, when cutting engineering plastic pipes, the equipment needs to cut to a fixed length. Before cutting, the cutting length needs to be measured and marked on the surface of the pipe. Cutting is then carried out according to these marks, which is cumbersome, increases workload, and reduces efficiency. It also makes filter maintenance difficult. Most cutting equipment has a dust collection mechanism, and the filter in this mechanism requires maintenance after prolonged use to ensure filtration effectiveness. The filter is usually installed inside the device, requiring disassembly of the device, removal of the filter, maintenance, reinstallation, and then reassembly. This entire maintenance process is tedious, increases workload, and reduces efficiency. To address these problems, we propose a cutting device for engineering plastic processing. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for processing engineering plastics, which has the advantages of facilitating fixed-length cutting and easy maintenance of the filter screen.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cutting device for processing engineering plastics, comprising a housing, a fixed rod fixedly sleeved on the inner wall of the housing, a telescopic rod slidably sleeved on the inner wall of the fixed rod, a baffle bolted to one end of the telescopic rod, a fixed cylinder slidably sleeved on the surface of the telescopic rod and bolted to the surface of the housing, a rotating cylinder threadedly connected to the surface of the fixed cylinder, a trapezoidal groove formed on the inner wall of the rotating cylinder, a sliding rod slidably connected to the inner wall of the trapezoidal groove, a pressure plate bolted to one end of the sliding rod, a limiting plate fixedly sleeved on the surface of the sliding rod, a first spring provided between the limiting plate and the inner wall of the fixed cylinder, and a cutting mechanism and a fixing mechanism provided on the top of the housing.

[0006] By adopting the above technical solution, the trapezoidal groove is moved by rotating the rotating cylinder. The movement of the trapezoidal groove causes the sliding rod to drive the pressure plate to relax under the action of the first spring, thereby pressing the telescopic rod. The baffle is moved to the required position, and then the rotating cylinder is tightened to make the pressure plate press and fix the telescopic rod. This method can facilitate fixed-length cutting, reduce workload, and improve cutting efficiency.

The movement of the transmission rod causes the snap-fit ​​connector to disengage from the snap-fit ​​hole, allowing the cover plate to be removed and the filter screen to be pulled out of the housing for maintenance. This method facilitates the maintenance of the filter screen, reduces workload, and improves maintenance efficiency.

[0009] The present invention is further configured such that: the cutting mechanism includes a fixed frame, the bottom of the fixed frame is bolted to the top of the box, a hydraulic lifting rod is bolted to the top of the fixed frame, a lifting frame is bolted to the bottom of the hydraulic lifting rod, a motor is bolted to the surface of the lifting frame, and a cutting blade is fixedly sleeved at the output end of the motor.

[0019] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0020] By adopting the above technical solution, one end of the snap-fit ​​connector is wedge-shaped, which facilitates the fixing of the cover plate.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model uses a rotating cylinder to move a trapezoidal groove. The movement of the trapezoidal groove causes the sliding rod to move the pressure plate under the action of the first spring, thereby pressing the telescopic rod. The baffle is moved to the required position, and then the rotating cylinder is tightened to press the telescopic rod firmly. This method facilitates fixed-length cutting, reduces workload, and improves cutting efficiency.

[0023] 2. This utility model uses a sliding block to move a pull rod that drives a transmission rod. The movement of the transmission rod disengages the snap-fit ​​connector from the snap-fit ​​hole, allowing the cover plate to be removed and the filter screen to be pulled out of the housing for maintenance. This method facilitates filter screen maintenance, reduces workload, and improves maintenance efficiency. Attached Figure Description
