Description

Technical Field

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

[0002] With the increasing use of plastic products, the importance of plastic recycling technology is becoming increasingly prominent. As a key piece of equipment in the plastic recycling process, the performance of plastic recycling crushers directly affects recycling efficiency and the quality of recycled plastics. However, existing plastic crushers still have many shortcomings in practical applications.

[0003] First, existing plastic crushers typically employ a single-stage crushing structure, capable of crushing plastics only once. This structure results in unevenly sized plastic particles after crushing, making it difficult to meet the uniformity requirements of subsequent processing techniques. Furthermore, existing crushers have limited functionality, with most lacking modular design and having fixed, non-removable crushing chambers, leading to difficulties in maintenance and cleaning, and making it impossible to adjust them according to actual needs. Therefore, this application proposes a plastic recycling crusher to address the aforementioned problems. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-3As shown, this utility model provides a technical solution: a plastic recycling crusher, including a primary crushing box 1. A feeding hopper 2 is connected to one side of the top of the primary crushing box 1 via a hinge, and the feeding hopper 2 is connected to the feed inlet 3 on one side of the top of the primary crushing box 1. The feeding hopper 2 is rotated to the top of the primary crushing box 1, and its feed inlet is connected to the feed inlet 3 on one side of the top of the primary crushing box 1. The feeding hopper 2 is inclined and can be rotated and stored at the top of the primary crushing box 1. The feeding hopper 2 prevents plastic fragments from flying out when the primary crushing box 1 crushes larger plastics. A secondary crushing box 4 is connected to the bottom of the primary crushing box 1. The bottom of the primary crushing box 1 is a constricted opening, and the top of the secondary crushing box 4 is an open opening. The constricted opening at the bottom of the primary crushing box 1 connects to the open opening at the top of the secondary crushing box 4. Two crushing rollers 5 are installed inside both the primary crushing box 1 and the secondary crushing box 4. The two crushing rollers 5 in the secondary crushing box 4 have small teeth. Two crushing rollers 5 are installed in the primary crushing chamber 1, and drive structures 6 are installed on the side walls of both the primary crushing chamber 1 and the secondary crushing chamber 4 to drive the crushing rollers 5. The two drive structures 6 are powered separately and include two interlocking gears and a drive motor. The two gears are respectively installed on the drive shafts of the two crushing rollers 5. The drive motor is installed on the protective housing and is connected to one of the drive shafts of the two crushing rollers 5. When the power supply of the drive structure 6 is turned on and the drive motor is started, the drive motor will drive one of the central shafts of the two crushing rollers 5 to rotate. The interlocking gears drive the two crushing rollers 5 to rotate in opposite directions. The plastic material to be crushed is fed into the primary crushing chamber 1 through the feeding hopper 2. The crushing rollers 5 in the primary crushing chamber 1 coarsely crush the plastic to form larger particles. The plastic particles after primary crushing enter the secondary crushing chamber 4 through the constriction port. The crushing rollers 5 in the secondary crushing chamber 4 have smaller teeth and finely crush the plastic, finally outputting small and uniform particles.

[0022] A first support frame 7 is installed at the bottom of the primary crushing box 1, and a second support frame 8 is installed at the bottom of the secondary crushing box 4. The first support frame 7 and the second support frame 8 are locked together by bolts 9. After the bolts 9 are released from locking the first support frame 7 and the second support frame 8, the secondary crushing box 4 can be pulled out from the bottom of the primary crushing box 1. The secondary crushing box 4 is then pushed into alignment with the contraction opening at the bottom of the primary crushing box 1, ensuring that the outer opening at the top of the secondary crushing box 4 is tightly connected to the contraction opening of the primary crushing box 1. Then, the first support frame 7 and the second support frame 8 are locked together using bolts 9 to ensure a stable connection between the two crushing boxes, allowing for the grinding of powder in both crushing boxes. When cleaning, maintaining, or replacing the crushing roller 5, loosen the bolt 9 and pull the secondary crushing box 4 out from the bottom of the primary crushing box 1. Then, disassemble the housings of the primary crushing box 1 and the secondary crushing box 4. If only coarse crushing is required, the primary crushing box 1 can be used alone, and the secondary crushing box 4 does not need to be installed. If fine crushing is required, the secondary crushing box 4 can be used alone. This method allows the primary crushing box 1 and the secondary crushing box 4 to be used separately to meet different plastic recycling crushing requirements. It also facilitates the maintenance, replacement, or cleaning of residual plastic inside the crushing roller 5, greatly improving the maintainability and service life of the equipment.

[0023] The operational steps for this application are as follows:

[0024] Push the secondary crushing box 4 into the constricted opening at the bottom of the primary crushing box 1 and align it, ensuring that the outer opening at the top of the secondary crushing box 4 is tightly connected to the constricted opening of the primary crushing box 1; then use bolts 9 to lock the first support frame 7 and the second support frame 8 to ensure a stable connection between the two crushing boxes.

[0025] Rotate the feeding hopper 2 to one side of the top of the primary crushing box 1, and connect the feeding port of the rotating feeding hopper 2 with the feeding port 3 on one side of the top of the primary crushing box 1.

[0026] When the power supply to the drive structure 6 is turned on, the drive motor is started. The drive motor will drive the central shaft of one of the two crushing rollers 5 to rotate. The two crushing rollers 5 will rotate in opposite directions by the meshing gears. The plastic material to be crushed is put into the primary crushing box 1 through the feeding hopper 2. The crushing rollers 5 in the primary crushing box 1 coarsely crush the plastic to form larger particles. The plastic particles after primary crushing enter the secondary crushing box 4 through the constriction port. The crushing rollers 5 in the secondary crushing box 4 have smaller teeth and finely crush the plastic, finally outputting small and uniform particles.

[0027] When cleaning, maintaining or replacing the crushing rollers 5 in the two-stage crushing box, loosen the bolts 9, pull the secondary crushing box 4 out from the bottom of the primary crushing box 1, and then disassemble the shells of the primary crushing box 1 and the secondary crushing box 4.

[0028] If only coarse crushing is required, the primary crushing box 1 can be used alone, and the secondary crushing box 4 is not needed. If fine crushing is required, the secondary crushing box 4 can be used alone, which can meet various crushing needs of plastics.
