[0001] This utility model relates to the field of shredder technology, specifically to a shredder. Background Technology

[0002] A shredder is a machine used for coarse crushing, generally for processing unprocessed raw materials or scraps in the recycling industry, making them smaller in size. Compared with other crushers, it has a lower cutter shaft speed, lower noise, and lower energy consumption.

[0003] When used for shredding rubber or smoked sheet rubber, the blade will generate high temperatures due to the large cutting work required, which may lead to deformation and other damage to the blade during subsequent use. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The system includes: a processing chamber body 1, a crushing box 7 fixed to the top of the processing chamber body 1, a feeding hopper 8 fixed to the top of the crushing box 7, crushing blades 9 installed inside the crushing box 7, and a main motor 2 for driving the crushing blades 9 to rotate. Two sets of opposing and oppositely oriented main motors 2 are installed inside the processing chamber body 1, and the output ends of the two sets of main motors 2 extend outward from the processing chamber body 1 and are connected to a pulley assembly 3. A reducer 4 is connected to the other end of the pulley assembly 3, and a coupling 5 and a speed ratio gear 6 are respectively installed between the reducer 4 and the crushing box 7, which can ultimately drive the crushing blades 9 to rotate. The two sets of crushing blades 9 installed inside the crushing box 7 are oppositely distributed and rotate in opposite directions. Therefore, when rubber material is fed into the feeding hopper 8, the rubber can be crushed.

[0028] The cooling chamber 11 is bolted to the surface of the crushing chamber 7. The upper and lower parts of the cooling chamber 11 are both sloping, making the cooling chamber 11 a triangular structure. The interior of the cooling chamber 11 is hollow, and an external air duct is connected to the cavity. A cold air fan is installed in the cavity of the processing chamber body 1. The air outlet of the cold air fan is connected to the air duct, allowing cold air to enter the cavity of the cooling chamber 11 through the air duct. An exhaust cylinder 13 and an exhaust side cylinder 14 are installed on the lower sloping surface of the cooling chamber 11. Two sets of exhaust side cylinders 14 are provided, and one set of exhaust cylinder 13 is placed between the two sets of exhaust side cylinders 14. Both sets of exhaust side cylinders 14 and exhaust cylinder 13 are connected to the cavity of the cooling chamber 11. The openings of exhaust cylinder 13 and exhaust side cylinder 14 face the crushing head 9, so that the exhaust cylinder 13 and exhaust side cylinder 14 can spray cold air onto the crushing head 9, providing cooling during the crushing operation of the crushing head 9 and improving its service life.

[0029] Above the two sets of exhaust side cylinders 14, two sets of exhaust upper cylinders 15 are also provided. An inlet 18 is provided at the front end of the exhaust upper cylinder 15 extending into the cavity of the cooling chamber 11. The opening of the inlet 18 is relatively large, and a rotating shaft is provided at the connection between the exhaust upper cylinder 15 and the cooling chamber 11, so that the exhaust upper cylinder 15 can rotate. The maximum rotation angle of the exhaust upper cylinder 15 will not affect the communication between the inlet 18 and the cavity of the cooling chamber 11. When tearing small volumes of rubber material, the crushing blade 9 closest to the middle has the most contact, while the crushing blades 9 on both sides have less contact. At this time, the tilt angle of the two sets of exhaust upper cylinders 15 can be adjusted to face the crushing blade 9 in the middle, thereby maximizing the use of cold cutting to reduce mass.

[0030] The lowermost part of the upper slope of the cooling chamber 11 is provided with a downward extension. Due to the design of the upper slope of the cooling chamber 11, the rubber that accidentally enters the cooling chamber 11 can move downward along the slope of the cooling chamber 11. The existence of the extension can greatly reduce the impact of the rubber on the exhaust side cylinder 14 and the exhaust middle cylinder 13. The positive and negative thread screw 12 is installed on one side of the cooling chamber 11. The meshing collar part 16 is meshed and sleeved on the outside of the positive and negative thread screw 12. The surface of the meshing collar part 16 is fixed with a drive connecting rod 17. A motor is provided at one end of the positive and negative thread screw 12. The drive connecting rod 17 can be moved laterally by the drive of the motor. A slide groove is provided at the top of the exhaust upper cylinder 15. A slider is provided in the slide groove. The bottom of the drive connecting rod 17 is rotatably connected to the slider. Therefore, as the drive connecting rod 17 moves, the slider of the drive connecting rod 17 can slide in the slide groove, thereby changing the operating angle of the exhaust upper cylinder 15.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
