Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene plastic particle processing, in particular to a polyethylene plastic particle cutting device capable of preventing adhesion. Background Art

[0002] In the processing of polyethylene plastic, irregular raw materials are usually heated and melted, and then extruded and molded by a screw machine to form long rod-shaped polyethylene plastic. Depending on the use occasion, the long rod-shaped polyethylene plastic needs to be cut into granules for subsequent processing of the polyethylene plastic. For example, a plastic granule cutting machine with publication number CN205969579U includes a frame and a motor installed on the base of the frame. Two upper and lower rollers that are arranged in parallel and cooperate with extrusion feeding are installed on one side of the cutting box near the feed port. When a large number of thin plastic strips need to be cut at one time, the sleeve is moved after the limit rod is rotated to increase the distance between the two sleeves. When a small number of thin plastic strips need to be cut at one time, the sleeve is moved after the limit rod is rotated to decrease the distance between the two sleeves. Regardless of the amount, centralized feeding can be performed, which is beneficial to the cutting of the cutting wheel and improves the cutting efficiency of the cutting wheel. However, the plastic granule cutting machine still has the following disadvantages during actual use:

[0003] Although the above-mentioned cutting machine can cut polyethylene plastic particles, when the feed speed is fixed, the cutting device cannot cut particles of different sizes, resulting in the need to replace different cutting devices. After the plastic is cut, some plastic particles will adhere to the cutting knife, thereby affecting the subsequent continuous cutting of the plastic. In view of the above problems, it is urgently necessary to carry out innovative design based on the original cutting device. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solutions: a polyethylene plastic particle cutting device for preventing adhesion, provided with a processing box, a fixed disk is fixedly penetrated on one side of the processing box, and plastic rods are penetrated at equal angles inside the fixed disk;

[0007] The anti-sticking mechanism is arranged inside the fixed plate, and the wind force of the anti-sticking mechanism comes from the drive of the motor.

[0008] Preferably, the driving assembly includes a first gear and a fourth gear fixedly mounted on the connecting shaft, and the third gear is meshingly connected to the bottom of the fourth gear, and the third gear is fixedly mounted on the outside of the movable column.

[0009] Preferably, a second gear is arranged on the side of the third gear, and the second gear corresponds to the first gear, and the diameter and the number of teeth of the first gear and the third gear are greater than the diameter and the number of teeth of the second gear and the fourth gear, so that when the fourth gear is meshed with the third gear for transmission, it has a deceleration effect, and when the first gear is meshed with the second gear for transmission, it has an acceleration effect.

[0010] Preferably, the movable column and the connecting rod are slidably connected, and the cross-sections of the internal cavities of the connecting rod and the movable column are both rectangular structures. The driving shaft is rotatably arranged on the fixed disk. When the movable column rotates, the cutting knife can be driven to rotate through the connecting rod and the driving shaft to cut the plastic.

[0011] Preferably, the end of the movable column away from the connecting rod is rotatably provided with a connecting column through a limit plate, and the limit plate is symmetrically distributed about the vertical axis of the connecting column, and the connecting column and the processing box are slidably connected, the connecting column can adjust the position of the movable column by sliding on the processing box, and the sliding distance is limited by the limit plate.

[0012] Preferably, the anti-sticking mechanism includes a fan blade fixedly mounted on the outside of the connecting shaft, and a protective box is provided on the outside of the fan blade, and the protective box is fixed to the inner wall of the processing box. At the same time, the top of the protective box is connected to the fixed cavity through an air pipe, and the wind force generated by the rotation of the fan blade can be transmitted to the fixed cavity through the air pipe.

[0013] Preferably, the fixed cavity is opened in a ring shape in the fixed disk, and air outlet holes are reserved at equal angles on one side of the fixed disk close to the cutting knife, and the air outlet holes are connected to the fixed cavity. At the same time, the air outlet holes and the plastic rods are staggered.

At this time, the transmission has an accelerating effect, and the movable column drives the cutting knife to rotate to achieve the slitting of small particles;

[0016] The movable column can rotate on the limit plate, while the connecting column can only slide on the processing box and maintain stability. The movable range of the connecting column and the movable column is limited by the setting of the limit plate to ensure that the meshing transmission of the two gears can be achieved after each movement;

[0017] 2. When the connecting shaft rotates, it can drive the fan blades to rotate synchronously, and then the generated wind force is transmitted from the air pipe to the fixed cavity, and finally discharged from the air outlet. Therefore, when the cutting knife cuts the plastic, the wind force can blow off some of the plastic particles adhering to the cutting knife, so as to avoid the adhesion of the plastic affecting the subsequent continuous cutting.
