DETAILED DESCRIPTION

[0019] The utility model provides a device for recycling injection molding waste, such as Figure 1-3 As shown, it includes a frame 1, on which a feeding chamber 2, a primary crushing chamber 3, a secondary crushing chamber 4, and a discharging chamber 5 are arranged in order from top to bottom. A primary crushing roller 8 is arranged in the primary crushing chamber 3, and the distance between the primary crushing roller 8 and the inner wall of the primary crushing chamber 3 is the size of the primary crushed particles. A motor 9 for driving the primary crushing roller 8 to rotate is arranged on the frame 1, and the output shaft of the motor 9 is connected to the roller shaft of the primary crushing roller 8 through a synchronous belt transmission.

[0020] A pair of secondary fixed crushing rollers 10 and secondary movable crushing rollers 11 with adjustable channel sizes are arranged in the secondary crushing chamber 4. The distance between the secondary fixed crushing rollers 10 and the secondary movable crushing rollers 11 and the distance between the secondary fixed crushing rollers 10, the secondary movable crushing rollers 11 and the inner wall of the secondary crushing chamber 4 are the size of the secondary crushed particles. A motor 12 for driving the secondary fixed crushing rollers 10 to rotate is arranged on the frame 1.

[0021] like Figure 1-2 As shown, the secondary movable crushing roller 11 is adjusted by an adjusting component, which includes a gear 13, a gear 2 14, an arc slide 15, and a fixed nut 16. The gear 13 and the gear 2 14 are coaxially connected to the secondary fixed crushing roller 10 and the secondary movable crushing roller 11, respectively, and mesh with each other. The output shaft of the motor 2 12 is connected to the gear 1 13 through a synchronous belt drive, and the secondary fixed crushing roller 10 and the secondary movable crushing roller 11 are driven to rotate through the gear 1 13 and the gear 2 14. The arc slide 15 is set in an arc shape with the distance between the axes of gear 1 13 and gear 2 14 as the radius. The rotating shaft of gear 2 14 is slidably adapted on the arc slide 15 and is opened on both sides of the secondary crushing chamber 4. In order to position the rotating shaft of gear 2 14 on the arc slide 15 after adjustment, the rotating shafts of the two ends of the secondary movable crushing roller 11 are connected to gear 2 14 at one end, and a threaded rod is pivotally connected to the other end through a bearing. The threaded rod passes through the arc slide 15, and a fixing nut 16 is threadedly sleeved on the threaded rod. The threaded rod is locked by the fixing nut 16 to achieve the positioning of the secondary movable crushing roller 11.

[0022] The discharge section of the secondary crushing chamber 4 is provided with a filter screen 17 that can slide left and right. Specifically, slide grooves are provided on both sides of the discharge section of the secondary crushing chamber 4, and the filter screen 17 is slidably adapted on the slide grooves. The filter screen 17 is symmetrically provided with through grooves 18 and fine holes 19. The aperture of the fine hole 19 is slightly larger than the diameter of the secondary crushing particle size. The areas occupied by the through groove 18 and the fine hole 19 are consistent with the size of the outlet of the secondary crushing chamber 4. When the crushed particles are large particles of the first level, the through groove 18 on the filter screen 17 is slid to align with the secondary crushing chamber 4. The through groove 18 is unobstructed above and below, so that large particles of waste of the first level can be discharged quickly. When the crushed particles are small particles of the second level, the fine holes 19 on the filter screen 17 are slid to align with the secondary crushing chamber 4 for strict filtering.

[0023] The device further comprises a material storage tank 6 and a spiral transmission channel 7. The entrance of the material storage tank 6 corresponds to the material discharging chamber 5. The spiral transmission channel 7 is used to transport the raw materials in the material storage tank 6 to a designated location. The spiral transmission channel 7 is an existing commercially available spiral conveyor. After the waste is crushed, it enters the material storage tank 6 from the material discharging chamber 5. Then, the spiral transmission channel 7 rotates to transmit the material out.

[0024] For the convenience of feeding, a step ladder 20 for climbing upwards is provided on the frame 1. Workers inject materials into the feed chamber 2 through the step ladder 20.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
