Summary of the invention

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the existing pulverizing device is usually carried out by two relatively rotating pulverizing rollers. After the PVC insulating material is pulverized by the two pulverizing rollers, some powdery debris will accumulate on the surface of the pulverizing rollers, and the accumulation will become thicker and thicker after extrusion, thereby affecting the pulverizing work.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] One end of the rotating rod 2 passes through the machine body 1 and is horizontally provided with a mounting groove. A plurality of through-holes are symmetrically provided on the surface of the rotating rod 2. A plug rod 5 is slidably inserted in the through-hole. The plug rod 5 is connected to the rotating rod 2 through a telescopic component. The telescopic component includes a telescopic spring 14 sleeved on the plug rod 5. The two ends of the telescopic spring 14 are respectively fixedly connected to the impact ball 6 and the rotating rod 2. The two ends of the plug rod 5 are respectively fixedly installed with the impact ball 6 and the ball 7. A reciprocating thread is provided on the surface of the end of the rotating rod 2 that passes through the machine body 1, and a slide plate 8 is threadedly sleeved. The slide plate 8 is limited in rotation by a limiting component. The limiting component includes two limiting rods 15 symmetrically and horizontally installed on the surface of the machine body 1. The slide plate 8 is slidably sleeved on the two limiting rods 15. A moving rod 9 is slidably inserted in the mounting groove. A plurality of groups of pressing components are fixedly sleeved on the moving rod 9. The pressing component includes two conical blocks 10 symmetrically and fixedly sleeved on the moving rod 9. The slide plate 8 is fixedly connected to the moving rod 9 through a connecting rod 11.

[0024] Put the PVC insulation material to be crushed into the machine body 1, and then start the driving motor 13. When the output shaft of the driving motor 13 drives one of the rotating rods 2 to rotate, under the transmission action of the two gears 12, the two rotating rods 2 will respectively drive the two crushing rollers 3 to rotate relative to each other, thereby achieving the crushing effect, and the crushed PVC insulation material will fall into the collection box 17;

[0025] When the rotating rod 2 rotates, the slide plate 8 threadedly sleeved on the rotating rod 2 will carry the moving rod 9 to reciprocate in the horizontal direction under the limiting action of the multiple limiting rods 15. During the movement, the inclined surfaces of the multiple conical blocks 10 will intermittently slide in contact with the multiple balls 7. Then, under the action of the pressing force, the multiple inserted rods 5 will carry the impact balls 6 to move away from the rotating rod 2. The impact balls 6 will collide with the cavity 4, that is, the inner wall of the crushing roller 3, so that the powdery debris accumulated on the outer wall of the crushing roller 3 will fall down due to the vibration force, so as to achieve the cleaning effect and avoid the accumulation of too much powdery debris, which will affect the crushing work.

[0026] When the conical block 10 no longer presses against the ball 7, the insertion rod 5 will quickly move and reset with the impact ball 6 under the elastic potential energy of the telescopic spring 14, and the impact ball 6 will no longer contact the cavity 4 wall.

[0027] The upper surface of the body 1 is rotatably connected to the cover 16 via a rotating shaft;

[0028] When crushing, the machine cover 16 can be rotated to cover the upper surface of the machine body 1, so that the crushing work is carried out in a relatively closed space, avoiding the dust generated during the crushing process from being scattered.

[0029] In the utility model, the PVC insulating material to be crushed is put into the machine body 1, and then the two crushing rollers 3 are controlled by the driving component to rotate relative to each other, so as to achieve the crushing effect. When the rotating rod 2 rotates, the slide plate 8 threadedly sleeved on the rotating rod 2 will carry the moving rod 9 to reciprocate in the horizontal direction under the limiting action of the limiting component. During the movement, the inclined surfaces of the multiple conical blocks 10 will intermittently slide with the multiple balls 7, and then under the action of the pressure, the multiple insertion rods 5 will carry the impact balls 6 to move in the direction away from the rotating rod 2, and the impact balls 6 will collide with the cavity 4, that is, hit the inner wall of the crushing roller 3, so that the powdery debris accumulated on the outer wall of the crushing roller 3 will fall down due to the vibration force, so as to achieve the cleaning effect and avoid the accumulation of too much powdery debris, which affects the crushing work.
