To this end, the utility model proposes a pulverizer for recycling waste plastics, which solves the problem that when the device is working for a long time, the temperature of the part connecting the generator and the pulverized workpiece will be very high. If the temperature cannot be reduced in time, the high temperature will cause harm to the parts of the device and accelerate their aging, thereby affecting the normal operation of the device and reducing its service life.

[0007] To achieve the above-mentioned purpose, the utility model proposes a pulverizer for recycling waste plastics, comprising a pulverizing box, a motor is fixedly connected to the side wall of the pulverizing box, a rotating shaft is fixedly connected to the side wall of the motor, the rotating shaft is rotatably connected to the side wall of the pulverizing box, a pair of latching teeth are rotatably connected to the inner side wall of the pulverizing box, and a cooling component is arranged inside the rotating shaft, wherein:

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The cooling component can be set up to achieve that when working, the motor drives the shaft to rotate, and the shaft rotates under the action of the meshing of the latch teeth and the latch teeth. As the latch teeth rotate, the slide block contacts the shaft, and the slide block moves into the latch teeth under the pressure of the shaft. The slide block will squeeze the baffle plate open. At this time, the cooling liquid in the latch teeth will be pushed by the push plate under the action of the elastic force of the push spring, so that it will be directly sprayed onto the shaft through the inner hole, thereby achieving the cooling effect. When the slide block leaves the contact with the shaft, the slide block moves out of the latch teeth again under the action of the elastic force of the return spring, and the baffle plate blocks the inner hole again under the action of the elastic force of the torsion spring. At this time, the liquid in the cavity cannot flow out of the inner hole.

[0016] The advantage of this design is that the liquid in the teeth will be discharged only when it comes into contact with the shaft, so that it can be accurately sprayed onto the shaft, improving the efficiency of the cooling liquid and reducing the loss of the cooling liquid. Secondly, by spraying the cooling liquid directly onto the shaft, it can effectively play a role in lubrication and cooling, and timely reduce the temperature of the shaft, which can greatly extend the service life of the shaft and reduce the company's economic pressure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, a pulverizer for recycling waste plastics includes a pulverizing box 1, and a plurality of bases 2 are fixedly connected to the bottom of the pulverizing box 1.

[0026] A cover plate 3 is provided on the top of the crushing box body 1 , a shaft rod 31 is fixedly connected to the bottom of the cover plate 3 , the shaft rod 31 is fixedly connected to the top of the crushing box body 1 , and a handle 32 is fixedly connected to the side wall of the cover plate 3 .

[0027] A motor 4 is fixedly connected to the side wall of the crushing box 1, and a rotating shaft 41 is fixedly connected to the side wall of the motor 4. When working, the rotating shaft 41 is driven to rotate by the motor 4, and rotates under the action of the meshing of the latch teeth 42 and the rotating shaft 41. The rotating shaft 41 is rotatably connected to the side wall of the crushing box 1, and a pair of latch teeth 42 are rotatably connected to the inner side wall of the crushing box 1. Both pairs of latch teeth 42 are meshed and connected to the side wall of the rotating shaft 41. The side walls of the two pairs of latch teeth 42 are respectively fixedly connected with an upper crushing wheel 43 and a lower crushing wheel 44. By arranging the upper crushing wheel 43 and the lower crushing wheel 44 up and down, the plastic can be repeatedly crushed, and the crushing efficiency is effectively improved.

[0028] The cooling assembly 5 is arranged inside the rotating shaft 41, and the cooling assembly 5 includes a slide block 51. As the latch tooth 42 rotates, the slide block 51 contacts the rotating shaft 41, and the slide block 51 moves into the latch tooth 42 under the pressure of the rotating shaft 41. The slide block 51 is slidably connected to the side wall of the latch tooth 42. The slide block 51 is provided with an inner hole 52 inside, and the side wall of the latch tooth 42 is provided with a slot 53. The slots 53 are distributed on both sides of the slide block 51. The side wall of the slide block 51 is fixedly connected with a rebound plate 511, and the rebound plate 511 is arranged in the slot 53. The slot 53 is arranged inside the return spring 54. When the slide block 51 leaves the contact with the rotating shaft 41, the slide block 51 moves out of the latch tooth 42 again under the action of the elastic force of the return spring 54. The two ends of the return spring 54 are respectively fixedly connected to the rebound plate 511 and the latch tooth 42. The inner wall of the latch tooth 42 A pair of torsion springs 55 are fixedly connected, and the side walls of the pair of torsion springs 55 are fixedly connected with baffles 56. The baffles 56 block the inner hole 52 again under the action of the elastic force of the torsion springs 55. At this time, the liquid in the cavity 57 cannot flow out from the inner hole 52. The baffle 56 is arranged below the inner hole 52. A cavity 57 is provided inside the latch tooth 42, and a slide groove 58 is provided on the side wall of the cavity 57. A push plate 59 and a push spring 510 are provided inside the cavity 57. The slide groove block 51 will squeeze the baffle 56 open. At this time, the cooling liquid in the latch tooth 42 will be pushed by the push plate 59 under the action of the elastic force of the push spring 510, so that it passes through the inner hole 52 and is directly sprayed onto the rotating shaft 41, thereby achieving the cooling effect. Both ends of the push plate 59 are slidably connected in the slide groove 58, and the two ends of the push spring 510 are respectively fixedly connected to the latch tooth 42 and the push spring 510.

[0029] In this way, it can be ensured that the liquid in the latch teeth 42 will be discharged only when it contacts the rotating shaft 41, so that it can be accurately sprayed onto the rotating shaft 41, thereby improving the use efficiency of the cooling liquid and reducing the loss of the cooling liquid. Secondly, by spraying the cooling liquid directly onto the rotating shaft 41, it can effectively play a role of lubrication and cooling, and timely reduce the temperature of the rotating shaft 41, which can greatly extend the service life of the rotating shaft 41 and reduce the company's economic pressure.

[0030] The upper crushing wheel 43 is arranged above the lower crushing wheel 44 . A protective shell 4101 is arranged inside the crushing box 1 , and the latch teeth 42 are arranged inside the protective shell 4101 .

[0031] A waste frame 6 is arranged inside the crushing box 1 , and an opening 7 is opened on the side wall of the crushing box 1 . An axis point 8 is rotatably connected inside the opening 7 , and a door panel 81 is fixedly connected to the side wall of the axis point 8 .

[0032] Working principle: When working, the motor 4 drives the rotating shaft 41 to rotate, and the rotating shaft 41 rotates under the action of the meshing of the latch tooth 42 and the rotating shaft 41. As the latch tooth 42 rotates, the slide block 51 contacts the rotating shaft 41, and the slide block 51 moves into the latch tooth 42 under the pressure of the rotating shaft 41, and the slide block 51 squeezes the baffle 56 open. At this time, the cooling liquid in the latch tooth 42 will be pushed by the push plate 59 under the action of the elastic force of the push spring 510, so that it is directly sprayed onto the rotating shaft 41 through the inner hole 52, thereby achieving the cooling effect. When the slide block 51 leaves the contact with the rotating shaft 41, the slide block 51 moves out of the latch tooth 42 again under the action of the elastic force of the return spring 54, and the baffle 56 blocks the inner hole 52 again under the action of the elastic force of the torsion spring 55. At this time, the liquid in the cavity 57 cannot flow out of the inner hole 52.

[0033] The plastics crushed by the upper crushing wheel 43 and the lower crushing wheel 44 will all fall into the waste frame 6. When it is necessary to recycle these plastics, it is only necessary to open the door panel 81 and take the waste frame 6 out of the crushing box 1.

[0034] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
