detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Fig. 1, a waste plastic shredder includes a feed port 1 and a crushing chamber, a feed pipe 2 is arranged below the feed port 1, and the feed pipe 2 is connected to the crushing chamber, so that The crushing cavity includes a first cavity and a second cavity, and a discharge port 7 is arranged below the crushing cavity, and a material collection bag 8 is connected to the bottom of the discharge port 7, so as to facilitate the crushed plastic particles Packing and transportation, the feed pipe 2 is provided with a blower 4 to prevent the feed pipe 2 from being clogged due to the large area of waste plastics, a screening plate 5 is provided between the first cavity and the second cavity, and the screening plate 5 is connected with the controller, and the size of the screen holes on the screening plate 5 can be adjusted according to the needs of users, so as to obtain plastic particles of qualified size. The first cavity is equipped with a crushing device, and the second cavity is equipped with a granulator. device, the crushing device is connected to the support base 10 by bolts, and one end of the granulation device is connected to the driving device 11, and the driving device 11 is generally a motor.

Described crushing device is made up of crushing main shaft 9 and the crushing cutter 3 that is arranged on the crushing main shaft 9, and described granulation device is made up of granulation main shaft 12 and the granulation hob 6 that is arranged on the granulation main shaft 12, and described The crushing cutter 3 is one of all-steel blades and inlaid steel blades. The feed inlet 1 and the discharge outlet 7 are both in the shape of an inverted bucket, which facilitates the rapid feeding and discharging of materials. The two sides of the first cavity are A blower 4 is arranged symmetrically, the tuyeres of the blower 4 and the crushing main shaft 9 are on the same horizontal line, the support base 10 is set up on the screening plate 5, and the length of the support base 10 is no more than 1/3 of the length of the screening plate 5 One, prevent the support seat 10 from being too long to affect the feeding speed of the pulverized plastic particles.

According to the above-mentioned waste plastic shredder, its working principle is: firstly waste plastic enters the first cavity from the feed port 1 through the feed pipe 2, the crushing cutter 3 starts to operate, and the waste plastic is crushed through program control. Cut the plastic to the required granular shape, and then select the particle size of the sieve through the controller. If it does not meet the requirements, you can continue to cut. After entering the second cavity, if you need to further granulate, start the granulation hob 6. If not, you can directly The crushed plastic enters into the material collection bag 8 through the discharge port 7 .

This kind of waste plastic shredder adds a second chamber, and the granulation device in it can choose whether granulation treatment is required according to the user's requirements. By adding a blower in the first chamber, on the one hand, it improves the cutting performance of the crushing cutter. Efficiency, on the other hand, also prevents the situation that there are too large plastic blocks that cannot be crushed. The structure is simple and the functions are complete.

The above-mentioned embodiments are used to further illustrate the utility model, but the utility model is not limited to these specific implementations. All modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be understood as falling within the protection scope of the present utility model.
