[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a Graham line sheath extrusion molding device as Figures 1-6 shown, which includes an extruder 1. A die head 2 is provided at the output end of the extruder 1. A removing component for removing burrs of the formed sheath is provided on one side of the die head 2. The removing component includes a scraper 3 provided on one side of the die head 2. A scraping hole 4 is opened at the top of the scraper 3. A storage box 5 for collecting burrs is provided on one side of the scraping hole 4. A fixing member for fixing the position of the scraper 3 is provided at the bottom of the scraper 3. A positioning member for fixing the position of the storage box 5 is provided at the bottom of the storage box 5. The fixing member includes a fixing plate 6 fixedly connected to the bottom end of the die head 2. A positioning plate 7 is fixedly connected to the top end of the fixing plate 6. The positioning plate 7 is fixedly connected to the other side of the scraper 3.

[0025] It should be noted that the provided extruder 1 and die head 2 are extruders of model SJ45-120. The shape of the discharge end of the die head 2 is the shape of the Graham line sheath. The provided fixing plate 6 is fixedly connected to the bottom end of the die head 2 by bolts. The provided positioning plate 7 is fixed to one side of the scraper 3 by welding. The positioning plate 7 and the scraper 3 are vertically arranged. When it is necessary to fix the position of the scraper 3, the position of the scraper 3 is fixed by fixing the position of the positioning plate 7. The provided positioning plate 7 is fixedly connected to the top end of the fixing plate 6 by symmetrically arranged bolts. The provided storage box 5 is used to collect the removed burrs.

[0026] Furthermore, during use, the rubber material is wrapped around the Graham line by the extruder 1 and the die head 2 and then output. During the cooling process of the rubber, uneven cooling may cause burrs to be generated. Then, the burrs are removed by the edge of the scraping hole 4 and collected by the storage box 5, thereby completing the production of the sheath and avoiding the occurrence of burrs after production.

[0027] Specifically, the positioning member includes a positioning frame 8 fixedly connected to the top end of the fixing plate 6. A connecting block 9 is fixedly connected to the bottom end of the storage box 5. The connecting block 9 is inserted through the top of the positioning frame 8. A clamping portion for fixing the position of the connecting block 9 is provided at the connection between the positioning frame 8 and the connecting block 9. The clamping portion includes a clamping hole 10 opened on one inner wall of the positioning frame 8. A clamping block 11 is inserted through one side of the connecting block 9. The clamping block 11 is clamped inside the clamping hole 10. A cavity 12 is opened on one side of the connecting block 9. A pushing block 13 is inserted through the cavity 12. The clamping block 11 is fixedly connected to one side of the pushing block 13. A spring 14 is provided on the other side of the pushing block 13. The spring 14 is inserted through the cavity 12.

[0028] It should be noted that the set positioning frame 8 is a square block with a square groove opened at the top. The opened square groove is adapted to the set connecting block 9 for inserting the connecting block 9 into the inside of the square groove. The opened cavity 12 is adapted to the set pushing block 13 to prevent the pushing block 13 from shaking inside the cavity 12. The set spring 14 has the characteristic of being deformable. When in use, it is used to push the pushing block 13 towards the side of the clamping block 11. One end of the spring 14 is connected to the connecting block 9, and the other end is fixedly connected to the inner wall of one side of the cavity 12. A hole for the clamping block 11 to pass through the cavity 12 is opened on the inner wall of the other side of the cavity 12. The diameter of this hole is smaller than the diameter of the pushing block 13 to prevent the pushing block 13 from passing through this hole and out of the cavity 12. When it is necessary to fix the position of the connecting block 9, the end of the clamping block 11 is inserted into the inside of the clamping hole 10. The upward movement of the clamping block 11 is restricted by the clamping hole 10. The movement of the connecting block 9 is restricted by the non-upwardly movable clamping block 11, thereby fixing the connecting block 9 inside the positioning frame 8.

[0029] Further, when it is necessary to clean the burrs collected inside the storage box 5, first press the clamping block 11 to move the clamping block 11 out of the clamping hole 10, and then move the connecting block 9 out of the positioning frame 8, so as to move the position of the storage box 5 and clean the burrs inside the storage box 5. After the cleaning is completed, move the storage box 5 to the top of the positioning frame 8, drive the connecting block 9 at the bottom of the storage box 5 and insert it into the top of the positioning frame 8. When moving to the bottom end of the clamping block 11 is in contact with the positioning frame 8, move the clamping block 11 in the direction of the cavity 12, so that the end of the clamping block 11 moves into the hole provided in the inner wall on the other side of the cavity 12. Then continue to move the position of the connecting block 9. When moving to the clamping block 11 moves into the positioning frame 8, release the pressing on the clamping block 11, and the spring 14 starts to recover its deformation, pushing the pushing block 13 and the clamping block 11 to the side away from the spring 14, and pushing until one end of the clamping block 11 is in contact with the inner wall on one side of the positioning frame 8. Finally, when moving to the clamping block 11 is aligned with the clamping hole 10, the clamping block 11 is pushed by the spring 14 and moves into the clamping hole 10 to complete the fixation of the position of the connecting block 9, and the position of the storage box 5 is fixed by the connecting block 9 with a fixed position.

[0030] Specifically, a material guiding plate 15 is fixedly connected to the top of the storage box 5, and baffles 16 are symmetrically fixedly connected to the front and back of the material guiding plate 15. The horizontal longitudinal section of the material guiding plate 15 is triangular.

[0031] It should be noted that the provided material guiding plate 15 is arranged at the top of the storage box 5. When fixing the position of the storage box 5, the material guiding plate 15 is in contact with the scraping plate 3. The burrs scraped off through the scraping holes 4 are guided to the inside of the storage box 5 through the hypotenuse of the material guiding plate 15, and the burrs are blocked by the baffles 16 on both sides of the material guiding plate 15 to prevent the scraped burrs from moving randomly.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
