Description

Technical Field

[0001] The utility model relates to the technical field of plastic waste treatment, in particular to a plastic waste crushing device. Background Technique

[0002] At present, when dealing with plastic waste, workers need to crush the plastic waste. After crushing, the volume of the plastic waste is greatly reduced, which is convenient for storage and transportation, reduces the storage and transportation costs, and the crushed plastic particles are easier to be processed in the subsequent processing process, such as regranulation, melt molding, etc., improving the processing efficiency. The crushed plastic waste can be used as a recycled raw material for the production of new plastic products, thereby reducing the dependence on virgin plastics and saving non-renewable resources such as petroleum.

[0003] During the process of high-speed rotation of the current plastic waste crushing and processing device to crush plastic waste, a large amount of heat will be generated due to the friction between the crushing blades and the waste, resulting in a rapid increase in the surface temperature of the blades. Most of the current plastic waste crushing and processing devices do not have a heat dissipation function, and the blade temperature will continue to rise, thereby affecting the crushing efficiency and the quality of plastic waste. When the high-temperature crushing blades contact the plastic waste, it is easy to soften or even melt the waste, which will not only reduce the crushing effect, but also may cause equipment blockage, affect the production progress, and increase the difficulty of subsequent processing.

The top of the water pump 8 is communicated with a plurality of water pipes 9. On the surface of the opposite sides of the mounting plate 6, a mounting frame 10 is fixed. The front and rear sides of one side of the mounting frame 10 are both provided with a rotating shaft 11 penetrating through. A plurality of spray heads 12 are fixed on the surface of the rotating shaft 11, and one end of the water pipe 9 penetrates through the mounting plate 6 and is communicated with the spray head 12. A position adjustment structure 13 is fixed on the left side of the mounting frame 10. Below the right side of the blanking cover 3, a blanking plate 14 is arranged, and a plurality of filter holes are opened on the surface of the blanking plate 14. On the right side of the bottom inner wall of the support frame 1 and below the blanking plate 14, a collection box 15 is fixed, and a vibration structure 16 is arranged inside the collection box 15.

[0024] The position adjustment structure 13 includes a fixed housing 131, a screw rod 132, a drive motor 133, a moving block 134, a rack plate 135 and a gear 136. The fixed housing 131 is fixed to the left side of the mounting frame 10. The screw rod 132 is rotatably connected to the inside of the fixed housing 131. The drive motor 133 is fixed to the front side of the fixed housing 131, and the output shaft of the drive motor 133 penetrates into the inside of the fixed housing 131 and is fixedly connected to the front end of the screw rod 132. The moving block 134 is slidably connected to the front and rear sides inside the fixed housing 131. The rack plate 135 is fixed to the bottom of the moving block 134. The gear 136 is fixed to the left side of the surface of the rotating shaft 11. The thread directions on the front and rear sides of the surface of the screw rod 132 are arranged in opposite directions, and the screw rod 132 penetrates through the moving blocks 134 on the front and rear sides and is in threaded connection with the moving blocks 134. The rack plate 135 is meshed with the gear 136. When the nozzle 12 sprays water downward for cooling treatment, the staff can turn on the drive motor 133, so that the output shaft of the drive motor 133 drives the screw rod 132 to rotate, and then the moving blocks 134 on both sides move in opposite or opposite directions, causing the lower rack plate 135 to move, and the gear 136 drives the rotating shaft 11 to rotate, continuously adjusting the water spraying position of the nozzle 12 to evenly cool the crushing blade body 4 and the plastic waste inside the installation shell 2.

[0025] The vibration structure 16 includes a vertical plate 161, a motor 162, a rotating rod 163 and a cam 164. The vertical plates 161 are fixed to the front and rear sides of the bottom inner wall of the collection box 15. The motor 162 is fixed above the surface of the front vertical plate 161. The rotating rod 163 is rotatably connected above the vertical plates 161, and the output shaft of the motor 162 penetrates through the vertical plate 161 and is fixedly connected to the front end of the rotating rod 163. The cam 164 is fixed to the surface of the rotating rod 163. The blanking plate 14 is hinged to the surface of the blanking cover 3. The number of cams 164 is two, and the cams 164 are slidably connected to the bottom of the blanking plate 14. Baffles 17 are fixed to the front and rear sides of the top of the blanking plate 14. When the crushed plastic falls on the surface of the blanking plate 14, the staff can turn on the motor 162, so that the output shaft of the motor 162 drives the rotating rod 163 to rotate, and the cam 164 pushes the blanking plate 14 to move, causing the blanking plate 14 to vibrate. Through the vibration treatment, the separation of the plastic waste and the water can be accelerated, and the water flows into the lower collection box 15 through the filter holes on the surface of the blanking plate 14 for storage.

[0026] Guide plates 18 are fixed to the left and right sides of the top of the collection box 15, and the guide plates 18 are integrally inclined. Through the arrangement of the guide plates 18, the collection range of the collection box 15 can be expanded, preventing the water from flowing to the outside and polluting the surrounding working environment.

[0027] Working principle: When the staff needs to crush plastic waste, the staff first turns on the device to make the crushing blade body 4 rotate. Then the staff pours the plastic to be crushed into the interior of the installation shell 2. At this time, after the rotating crushing blade body 4 contacts the plastic waste, it will carry out the crushing process. The crushed plastic then slides down from the blanking cover 3 onto the blanking plate 14. At this time, the staff turns on the water pump 8 and the drive motor 133 above. The water pump 8 pumps the water in the water tank 7 into the interior of the spray head 12, and the spray head 12 sprays the water downward. The drive motor 133 drives the rotating shaft 11 to rotate, causing the spray head 12 to swing back and forth, evenly spraying the cooling water inside the installation shell 2, thereby cooling the crushing blade body 4 and the plastic waste. At the same time, the staff turns on the motor 162 on one side, causing the blanking plate 14 to vibrate. When the water and plastic waste fall on the surface of the blanking plate 14, the vibrating blanking plate 14 can quickly separate the plastic waste from the water, so as to complete the crushing process of the plastic waste.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
