DETAILED DESCRIPTION

[0020] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes and the effects, the following will combine the drawings and the preferred embodiments to specifically describe the specific embodiments, structures, features and effects according to the utility model and their effects.

[0021] Please refer to Figures 1-4 As shown in the figure, the plastic plate raw material crusher comprises a crushing box body 4, a crushing mechanism 3 for cutting plastic plates is arranged in the inside of the crushing box body 4, a first feeding mechanism 1 and a second feeding mechanism 2 are symmetrically arranged above the crushing box body 4, wherein the first feeding mechanism 1 and the second feeding mechanism 2 are used for guiding the plastic plates so that the plastic plates avoid directly contacting the crushing mechanism 3 in a horizontal manner, thereby avoiding the problem that the waste plastic products in the flat state will be erected again when crushing, which is extremely easy to scratch the inner wall of the crushing box body, causing impact and splashing of the crushed plastic semi-finished products.

[0022] The crushing mechanism 3 comprises a first crushing roller 31 and a second crushing roller 32, wherein the first crushing roller 31 and the second crushing roller 32 are rotatably installed in the inside of the crushing box body 4, the first crushing roller 31 and the second crushing roller 32 are used for cutting and crushing the waste plastic plates by rotating towards each other, a discharge port 33 is arranged at the bottom of the crushing box body 4 for discharging the plastic fragments obtained by crushing through the discharge port 33, in this process, the first crushing roller 31 and the second crushing roller 32 are driven by a power machine box, in this step, the power machine box comprises a power motor and corresponding transmission equipment, so that the first crushing roller 31 and the second crushing roller 32 rotate towards each other to realize the crushing function of the waste plastic plates.

[0023] In the present application, the first feeding mechanism 1 and the second feeding mechanism 2 are respectively used for guiding the plastic plates, so the structures of the first feeding mechanism 1 and the second feeding mechanism 2 are the same, taking the first feeding mechanism 1 as an example, in the present application, the first feeding mechanism 1 comprises a feeding platform 5, wherein the feeding platform 5 is fixedly installed above the crushing box body 4, a pushing discharge plate 13 is arranged on the feeding platform 5 for tilting and pushing the waste plastic plates from the feeding platform 5 to the position of the crushing mechanism 3 to avoid laying flat on the crushing mechanism 3, and the angle of the pushing discharge plate 13 is adjustable, when the angle between the pushing discharge plate 13 and the horizontal is large, the plastic plates discharged through the pushing discharge plate 13 at this time fall on the feeding platform 5 in an inclined state, under the action of inertia and gravity, the plastic plates fall from the feeding platform 5 on the crushing mechanism 3 in an inclined manner, when the inclination angle of the pushing discharge plate 13 is small, the pushing discharge plate 13 is used for moving on the feeding platform 5 to directly push the small plastic plates from the feeding platform 5 to facilitate the crushing treatment of the plastic plates by the crushing mechanism 3.

[0024] The pushing down plate 13 is rotatably installed on two rotating shafts, and the ends of the two rotating shafts are rotatably installed with a connecting rotating rod 12 and a first rotating rod 11.
