[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: an extrusion device for cable production, including an extruder 1, a connecting tube 2 is detachably installed on the left end of the extruder 1, and the connecting tube 2 is the discharge part of the existing extruder 1. The outer wall of the connecting tube 2 is fixedly connected with a square frame 3, and the square frame 3 has a card slot, and the card slot is a vertical opening and a horizontal opening, which can allow a card block 8 to enter the vertical opening from the horizontal opening. Figure 5The inner wall of the bottom end of the square frame 3 is elastically connected to the limit block 5 through the return spring 4. The limit block 5 is an inclined surface. When squeezed, the limit block 5 will slide along the inner wall of the square frame 3. A blocking mechanism is provided at the left end of the connecting pipe 2. The right end of the mounting ring 6 matches the outer wall of the mold sleeve 9. After the mounting ring 6 is installed on the connecting pipe 2, the mold sleeve 9 can be positioned by using the right end of the mounting ring 6. The outer wall of the blocking mechanism is fixedly connected to the L frame 7. The outer wall of the L frame 7 is slidably connected to the clamping block 8. The outer wall of the L frame 7 is provided with a notch, which allows the clamping block 8 to slide along the notch. The inner wall of the connecting pipe 2 is detachably installed with the mold sleeve 9.

[0034] Reference Figure 1 , Figure 6 and Figure 7 An exhaust pipe 10 is provided at the top of the extruder 1. One end of the exhaust pipe 10 is connected to the inside of the extruder 1, so that harmful gases in the extruder 1 can enter the filter box 11 through the exhaust pipe 10. The top of the extruder 1 is fixedly connected to the filter box 11. The inner wall of the filter box 11 is plugged with a mounting frame 12. The mounting frame 12 has activated carbon, which can filter harmful gases. A handle 13 is fixedly connected to the right end of the mounting frame 12, and the mounting frame 12 is moved by the handle 13. The inner wall of the right end of the handle 13 is elastically connected to a top block 15 through a positioning spring 14. The left end of the handle 13 is penetrated and slidably connected with a positioning tube 16. The bottom end of the positioning tube 16 is inclined. When squeezed, the positioning tube 16 will move vertically along the left end of the handle 13. The inner wall of the right end of the handle 13 is fixedly connected to one end of the positioning spring 14. When the top block 15 moves to the right, the positioning spring 14 will be compressed. When resetting, the elastic force of the positioning spring 14 is used to reset the top block 15. The other end of the positioning spring 14 is fixedly connected to the right end of the top block 15. The top block 15 is slidably connected to the inner wall of the handle 13. The left end of the top block 15 contacts the bottom end of the positioning tube 16. The outer wall of the positioning tube 16 has a convex part, which can make the descending position of the positioning tube 16 certain, so that the inclined surface of the positioning tube 16 can be squeezed, and the top end of the positioning tube 16 is plugged into the top inner wall of the filter box 11. The top inner wall of the filter box 11 is provided with a notch corresponding to the positioning tube 16, which can allow the positioning tube 16 to be plugged with it to limit the installation frame 12.

[0035] Reference Figure 3-Figure 5 The inner wall of the bottom end of the frame 3 is fixedly connected to one end of the return spring 4. When the limit block 5 moves downward, the return spring 4 will be compressed. When resetting, the limit block 5 is reset with the elastic force of the return spring 4. The other end of the return spring 4 is fixedly connected to the inner side wall of the limit block 5. The limit block 5 penetrates and is slidably connected to the inner wall of the frame 3. The limit block 5 is plugged into the bottom end of the L frame 7, and the clamping block 8 is clamped with the inner wall of the frame 3.

[0036] Reference Figure 1-Figure 3The blocking mechanism includes a mounting ring 6, which is inserted into the side wall of the connecting pipe 2. The right end of the mounting ring 6 matches the outer wall of the mold sleeve 9. After the mounting ring 6 is installed in the connecting pipe 2, the mold sleeve 9 can be positioned using the right end of the mounting ring 6. The outer wall of the mounting ring 6 is fixedly connected to the L frame 7.

[0037] Working principle: First, when the mold sleeve 9 needs to be disassembled and assembled, just move the card block 8 upwards to make the card block 8 coincide with the horizontal opening of the square frame 3, and then pull the limit block 5 downwards to allow the limit block 5 to compress the reset spring 4, so that the limit block 5 and the bottom opening of the L frame 7 are separated to release the limit on the L frame 7, so that the mounting ring 6 can be moved out from the inner wall of the connecting tube 2, and the L frame 7 and the inner wall of the square frame 3 are separated. At this time, the mold sleeve 9 is moved out from the inner wall of the connecting tube 2, and finally the limit block 5 is released and the reverse elastic force of the reset spring 4 is used to reset the limit block 5.

[0038] When the mold sleeve 9 needs to be installed, it is only necessary to place the mold sleeve 9 on the inner wall of the connecting tube 2 first, and then insert the L frame 7 into the inner wall of the frame 3, so that the block 8 can enter from the horizontal opening of the frame 3, and use the right end of the L frame 7 to squeeze the inclined surface of the limit block 5, so that the limit block 5 moves downward and compresses the reset spring 4. When the limit block 5 and the bottom opening of the L frame 7 coincide with each other, use the reverse elastic force of the reset spring 4 to reset the limit block 5, so that the limit block 5 and the bottom end of the L frame 7 are plugged in, and the mounting ring 6 and the outer wall of the connecting tube 2 are plugged in to cover the mold sleeve 9. At this time, move the block 8 downward to let the block 8 and the vertical opening of the frame 3 coincide, and use the vertical opening of the frame 3 to block the block 8, so that the mounting ring 6 can be bidirectionally limited.

[0039] When the extruder 1 is in use, the gas in the extruder 1 will enter the filter box 11 through the exhaust pipe 10, and the activated carbon on the installation frame 12 will be used to adsorb and purify the gas to prevent the staff from adsorbing harmful gases. When the activated carbon on the installation frame 12 needs to be replaced, it is only necessary to press the top block 15 by hand and compress the positioning spring 14 to prevent the top block 15 from contacting the bottom end of the positioning tube 16, and use the own gravity of the positioning tube 16 to move downward to separate the positioning tube 16 from the top notch of the filter box 11, and then use the handle 13 to move the installation frame 12 out for replacement. After the replacement is completed, the installation frame 12 is inserted into the inner wall of the filter box 11. When the top notch of the filter box 11 coincides with the positioning tube 16, release the top block 15 and use the reverse elastic force of the positioning spring 14 to reset the top block 15, so that the top block 15 squeezes the bottom end inclined surface of the positioning tube 16 to move upward and plug into the top inner wall of the filter box 11, so that the entire installation frame 12 can be limited.
