Description

Technical Field

[0001] The invention relates to the technical field of plastic barrel processing, in particular to a plastic barrel trimming device. Background Art

[0002] When processing and molding plastic barrels, it is necessary to prepare the main raw materials of the plastic barrels first. Plastic particles such as polyethylene or polypropylene are usually used. Then the inspected plastic particles are sent to the pretreatment equipment for heating and drying to ensure that there is no moisture in the raw materials. After the pretreatment of the raw materials is completed, the plastic particles are sent to the extruder. The extruder heats and melts the plastic particles through high temperature and high pressure, and then extrude the molten plastic into shape. The mold of the extruder will form the shape and size of the plastic barrel according to the design requirements. The plastic barrel after extrusion needs to enter the cooling system immediately. The cooling system uses blowing or water circulation to The plastic barrel is cooled rapidly to keep the required shape and structure. The formed plastic barrel is then placed on a trimming device, which is controlled to cut off the flash, burrs and protruding parts of the formed plastic barrel to produce a standard plastic barrel. However, in the trimming device for plastic barrels commonly found on the market, the plastic barrel is prone to rotation or dislocation after being subjected to force during the rotary slicing process. Moreover, when trimming, a single-knife trimming is usually used, which causes uneven force on the plastic barrel and makes it prone to tilting, affecting the uniformity of trimming. In addition, during the trimming process, the cutter is prone to contact with the pad, causing wear on the cutter, affecting its service life. Summary of the invention

[0008] The present invention provides a plastic barrel trimming device, which has the following beneficial effects:

[0009] When trimming, the plastic barrel can be controlled to be placed upside down so that the top of the jacking structure contacts the inner top of the plastic barrel. The hydraulic cylinder drives the mounting plate assembly, the rotating plate assembly, the pushing assembly, and the mounting components to move downward together, so that the bottom end of the pushing assembly contacts the top of the plastic barrel through the contact assembly and the anti-skid assembly. The spring 1 inside the pushing assembly and the spring 2 inside the jacking structure are stressed together to squeeze the plastic barrel to limit and fix it. While the contact assembly and the anti-skid assembly fix the plastic barrel in an anti-skid manner, the anti-skid assembly is a long strip structure, which limits the rotation of the plastic barrel when trimming, thereby improving the fixing effect of the plastic barrel and preventing the plastic barrel from being displaced or rotated.

[0010] Before trimming, the displacement of the pulling component can be controlled by the handwheel component, and the two ends of the pulling component can move simultaneously inside the two inclined grooves, so that the force-bearing rod pulls the two support plate components and the cutting head component to move together, generating a force for opposite adjustment, so that the cutting head component can trim plastic barrels of different sizes, thereby improving the flexibility of trimming.

[0011] When trimming, the contact heads of the two support plate components are stressed together, and the rotating wheels of the contact heads contact the edge of the plastic barrel, pressing and fixing the plastic barrel, while allowing the cutting head component to be inserted into the excess flash. When rotating to trim, the two cutting head components rotate together to trim, thereby improving the trimming efficiency and stability and preventing the plastic barrel from being unevenly stressed and tilted.

[0012] When trimming, the cutting head component passes through the flash and is inserted into the interior of the pad. Since the jacking structure and the pushing assembly fix the plastic barrel with the help of spring 1 and spring 2, the plastic barrel is in slight contact with the pad and will not be heavily stressed. When rotating to trim, the cutting head component drives the pad and the support to rotate together, and the bottom of the support and the top of the rotating head rotate smoothly, so that the cutting head component can be protected during trimming, so that the cutting head component will not be worn and the service life is increased.
