Description

Technical Field

[0001] The utility model relates to the technical field of plastic raw material cutting, and in particular mainly relates to a plastic raw material anti-sticking cutting device. Background Art

[0002] Plastic refers to a plastic material that is processed and formed with high molecular weight synthetic resin as the main component and appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc.

[0003] At present, plastic raw materials need to continue cutting during processing. During the cutting process, they are generally cut quickly by a cutting knife that moves up and down. However, in the process of the cutting knife cutting the plastic, since the plastic has a certain viscosity, the cutting knife may adhere to the plastic, and the plastic may be lifted up when the cutting knife rises, causing the plastic to deform and reduce the quality of the plastic cutting. In view of this, we propose a plastic raw material anti-sticking cutting device. Utility Model Content

[0010] Preferably, the cutting mechanism comprises a reducer, a motor is fixedly connected to the outer wall of the reducer, and a rotating shaft is fixedly connected to the output shaft of the reducer. The speed of the motor rotating shaft can be reduced by using the reducer.

[0011] Preferably, a cam is fixedly connected to one end of the rotating shaft away from the reducer, a connecting rod is hinged to one end of the cam away from the rotating shaft, a fixed seat is fixedly connected to the bottom of the connecting rod, a fixed plate is fixedly connected to the lower side of the fixed seat, a cutting knife is fixedly connected to the outer wall of the fixed plate, and the cam can be driven to rotate by rotating the rotating shaft, so that the connecting rod can reciprocate up and down.

[0012] Preferably, the hinge axis of the cam and the connecting rod is no longer on the same horizontal line as the rotating axis.

[0013] Preferably, the fixed seat is slidably connected to the guide seat, and the guide seat limits the fixed seat, so that the fixed seat is more stable when performing lifting movement.

[0014] Preferably, the scraper is in contact with the outer wall of the cutting knife.

[0016] The beneficial effects of this application are:

[0017] (1) The anti-adhesion cutting device for plastic raw materials can quickly cut the plastic raw materials through the coordinated use of the cutting mechanism and the anti-adhesion mechanism. During this process, the elastic telescopic rod descends, so that the pressure ring presses the plastic raw materials to be cut, and the cutting knife cuts the plastic raw materials stably. After the cutting is completed, the reaction force of the elastic telescopic rod on the plastic raw materials prevents the plastic raw materials from sticking when the cutting knife rises.

[0018] (2) The anti-sticking cutting device for plastic raw materials uses a cutting mechanism. When the telescopic end of the elastic telescopic rod is retracted, the cross bar drives the scraper to move. When the cutting knife rises and resets, the cross bar drives the scraper to reset, cleans both sides of the cutting knife, and scrapes off the attached plastic impurities, thereby improving the subsequent cutting effect of the plastic raw materials. In addition, during the reset process of the scraper moving downward, under the action of the reset spring and the sliding block, the scraper shakes after moving to the bottom, which is convenient for shaking off the plastic impurities attached to the scraper, thereby improving the subsequent cleaning effect of the cutting knife.
