AI Technical Summary
Because the roll roll is large in size and hard in texture, it is directly crushed by the crushing roller, and the crushing effect is poor, which affects the crushing and recycling efficiency of the roll roll.
A scrap roll recycling device is designed, including a preheating shell, a cutting shell and a crushing shell. The rolling roll is preheated by the electric heating tube in the preheating shell to reduce its hardness. Then, the rolling rolls are cut into small pieces by the cutting roller in the cutting shell, and then crushed and grinded by the crushing roller in the crushing shell, and finally screened through the screening frame to achieve effective crushing and recycling of the rolls.
Through preheating and cutting steps, the hardness and volume of the rolls are reduced, making them easier to break, significantly improving the crushing and recycling efficiency of the rolls, and avoiding the re-recycling of the defective products.

[0008] Preferably, the cutting assembly comprises a cutting roller, and a cutting knife is fixedly connected to the outside of the cutting roller.
[0009] Preferably, two cutting rollers are provided, and the two cutting rollers are installed inside the cutting shell.
[0010] Preferably, the interior of the preheating shell is arranged in an inclined shape, the top of the preheating shell is fixedly connected to a support frame, the inner side of the support frame is fixedly connected to a cylinder, and the bottom of the cylinder is fixedly connected to the top of the sealing plate.

[0013] Preferably, one end of the discharge pipe is fixedly connected to one end of the crushing shell, and the screening frame is arranged to be inclined.
[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0015] First, the utility model opens the shell cover on the top of the preheating shell, then puts the scrapped roller into the preheating shell from the feeding port on the top of the preheating shell, closes the shell cover, and is provided with a heat insulating pad on the outside of the preheating shell to prevent the staff from being injured by touching the preheating shell during preheating. Then, the electric heating tube in the preheating shell is started to heat, so that the scrapped roller in the preheating shell starts to be preheated. After a certain period of preheating, the hardness of the scrapped roller is reduced. Then, the sealing plate is driven to rise by starting the cylinder inside the support frame, so that the preheating shell is connected with the cutting shell. Since the interior of the preheating shell is arranged to be inclined, the preheated scrapped roller slides into the cutting shell, and then the cutting roller is driven to rotate by the motor outside the cutting roller, so that the cutting knife cuts the preheated scrapped roller into small pieces, which is convenient for subsequent crushing. Then, the small pieces of scrapped roller enter the crushing shell, and then the crushing roller is driven by the motor outside the crushing roller to crush and grind the small pieces of roller, and then discharged from the pipeline at the bottom of the crushing shell, completing the crushing operation, and achieving the effect of convenient crushing.
[0016] Secondly, the utility model makes the scrapped rollers after grinding fall into the screening frame, and then drives the screening frame to vibrate and screen through the vibration motor, so as to screen the scrapped rollers after grinding, and the scrapped rollers that do not pass through the screening frame slide into the interior of the auger, and then the unfiltered scrapped rollers are re-input to the top of the crushing roller by starting the discharge pipe on the left side of the auger, and are crushed and ground again. The rubber sleeve can seal the gap between the screening frame and the crushing shell to prevent the scrapped rollers from falling from the gap. Due to the softness of the rubber sleeve, it avoids interfering with the vibration of the screening frame, thereby completing the screening operation. BRIEF DESCRIPTION OF THE DRAWINGS
