[0041] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please refer to Figures 1 to 6 , Example 1:

[0043] The utility model proposes a PI protective film recycling device based on flexible copper clad laminate production, comprising: a crushing tube 1, a first bearing seat 101, a retaining ring 102, a suction fan 2, a support mounting frame 3, an air guide hood 4, a PI protective film suction nozzle 401, a positioning ring 402, a crushing motor 5, a drive shaft 6, crushing teeth 601, a limiting ring 602, a short hexagonal transmission shaft 603, a retaining ring 7, a short plug shaft 701, and a second bearing seat 702. The air guide hood 4 is threadedly fastened to the opening at the head end of the crushing tube 1, the drive shaft 6 is rotatably mounted at the inner center of the crushing tube 1, and a plurality of circles of crushing teeth 601 are welded and arranged at equal intervals on the drive shaft 6;

[0044] An elbow is welded to the tail end of the crushing tube 1, and a first bearing seat 101 is welded to the side wall of the elbow in the middle of the large curved arc part of the outer ring. The tail end of the drive shaft 6 passes through the side wall of the elbow and slides with the bearing inside the first bearing seat 101; a crushing motor 5 is threadedly fastened to the position of the elbow near the first bearing seat 101, and a hexagonal transmission hole is opened at the head end of the rotating shaft of the crushing motor 5, and a short hexagonal transmission shaft 603 is welded to the tail end of the drive shaft 6, and the short hexagonal transmission shaft 603 is plugged into the hexagonal transmission hole;

[0045] The multiple rings of crushing teeth 601 and the drive shaft 6 together form a mechanism for rotating and crushing the PI protective film waste. When the crushing tube 1 is blocked, the rotating crushing mechanism needs to be removed from the crushing tube 1 to clear the blockage. The short hexagonal drive shaft 603 is plugged into the hexagonal drive hole to connect the drive shaft 6 to the crushing motor 5.

[0046] A retaining ring 7 of a suitable shape and size is inserted into the opening portion of the head end of the drive shaft 6, and a retaining ring 102 is welded into the opening portion of the head end of the drive shaft 6, and the retaining ring 7 is in abutment with the retaining ring 102; a second bearing seat 702 is welded at the inner center position of the retaining ring 7, and the head end of the drive shaft 6 and the bearing inside the second bearing seat 702 are slidingly matched; a limiting ring 602 is welded and sleeved on the head end portion of the drive shaft 6, and the limiting ring 602 is in abutment with the inner ring of the bearing inside the second bearing seat 702; a positioning ring 402 is welded into the opening of the tail end of the air guide cover 4, and the positioning ring 402 is in abutment with the retaining ring 7; the retaining ring 7 is clamped and positioned between the positioning ring 402 and the retaining ring 102;

[0047] Through the second bearing seat 702, the retaining ring 7 can provide auxiliary support and positioning for the drive shaft 6, thereby enhancing the stability of the rotary crushing mechanism in the crushing tube 1.

[0048] When the air guide hood 4 is threadedly connected to the head end of the crushing tube 1 through the positioning ring 402, the retaining ring 7 can be clamped and positioned. When the air guide hood 4 is disassembled from the crushing tube 1 and the positioning ring 402 is separated from the retaining ring 7, the retaining ring 7 can be loosened. When the retaining ring 7 is clamped and positioned, the rotating crushing mechanism as a whole can be blocked and positioned in the crushing tube 1 through the inner ring of the bearing inside the second bearing seat 702 and the limiting ring 602, and the driving shaft 6 is positioned and maintained in a state of being tightly connected to the crushing motor 5 for transmission. When extracting and disassembling the rotating crushing mechanism, the air guide hood 4 and the crushing tube 1 need to be disassembled and the retaining ring 7 loosened before the extraction can be carried out.

[0049] Specifically, since the inner ring of the bearing inside the second bearing seat 702 is in contact with the limiting ring 602, the retaining ring 7 can also block the positioning drive shaft 6 when it is clamped and positioned, so that the drive shaft 6 remains in a state of being tightly connected and transmitted with the crushing motor 5. When the retaining ring 7 is loosened, the second bearing seat 702 loses its blocking and holding force on the limiting ring 602 and the drive shaft 6, and can also loosen the drive shaft 6, so that the drive shaft 6 is in a state of being able to be automatically disassembled and separated from the crushing motor 5, and then the inner ring of the bearing inside the second bearing seat 702 is used to lock the drive shaft 6. The power transmission between the ring and the limit ring 602 only requires disassembling the wind guide cover 4 to loosen or tighten the retaining ring 7, which can complete the loosening of the drive shaft 6 and the crushing motor 5. Compared with the existing technology, the loosening and tightening operations of the drive shaft 6 and the crushing motor 5 and the loosening and tightening operations of the retaining ring 7 can be implemented at one time, eliminating the trouble of performing the above two loosening and tightening operations step by step when clearing and unblocking the crushing pipe 1 and disassembling the rotary crushing mechanism. The rotary crushing mechanism can be quickly disassembled and assembled, and is better suitable for the use needs of frequently clearing and unblocking the crushing pipe 1.

[0050] Preferably,

[0051] A PI protective film suction nozzle 401 is welded on the head end blocking plate of the air guide cover 4.

[0052] Preferably,

[0053] A circle of short insert shafts 701 is welded around one side of the retaining ring 7 facing the retaining ring 102 , and the circle of short insert shafts 701 penetrates and is plugged into the retaining ring 102 .

[0054] Preferably,

[0055] The top end of the vertical suction pipe on the suction fan 2 is screw-fastened with the tail end of the elbow.

[0056] Based on the first embodiment, the second embodiment:

[0057] The support mounting frame 3 is composed of an I-shaped base and two vertical support rods symmetrically welded to the top of the I-shaped base.

[0058] Preferably,

[0059] The crushing pipe 1 is welded and fixed to the top ends of two vertical support rods.

[0060] Working principle: When in use, under the negative pressure suction of the suction fan 2, the film edges cut from the PI protective film or other forms of waste film enter the crushing tube 1 in turn through the PI protective film suction nozzle 401 and the air guide cover 4. Through the drive shaft 6, the crushing motor 5 can drive multiple circles of crushing teeth 601 to rotate at high speed, cutting and crushing the waste film sucked into the crushing tube 1. The film fragments formed after crushing are continuously transported backward by the suction fan 2, blown out through the discharge pipe of the suction fan 2 and transported to the subsequent recycling process.
