Description

Technical Field

[0001] The present invention relates to the technical field of nylon carbon fiber extrusion equipment, in particular to a high-efficiency hot-melt extrusion device for nylon carbon fiber and an extrusion process thereof. Background Art

[0002] Nylon carbon fiber is a type of conductive nylon, which is made by adding carbon fiber to a nylon base material. The material adds high-rigidity carbon fiber to the performance of nylon, giving the material a higher modulus and rigidity.

[0003] In the process of nylon carbon fiber production, extrusion equipment is needed to extrude the hot melt generated by the melting of raw materials, and then produce nylon carbon fiber through subsequent processing. In the existing technology, the hot melt is extruded into strips under the extrusion of the extrusion plate, which is convenient for subsequent processing and production. It is troublesome to clean up, and some raw materials remaining inside cannot be cleaned up, which affects the next use and production. When the material is heated and plasticized, the plastic at the center of the extrusion barrel is heated slowly and unevenly, which affects the quality of the extruded product. At the same time, bubbles will be generated inside after hot melting, which is not conducive to product molding. Summary of the Invention

[0016] Furthermore, a high-efficiency hot melt extrusion process for nylon carbon fiber comprises the following steps:

[0017] S1: When extruding nylon carbon fiber, the nylon carbon fiber is heated from the feeding barrel to become a molten state. The servo motor drives the belt to move, and the belt drives the second transmission wheel to rotate. The second transmission wheel drives the rotating shaft to drive the spiral rotating plate to extrude and transport inside the sleeve. When the rotating shaft rotates, it can drive the rotating plate to rotate, so that the teeth on the rotating plate and the driven gear are engaged and transmitted. When the driven gear passes between the spherical tooth plate and the teeth, the driven gear can drive the rotating rod to rotate in the opposite direction, so that the stirring scraping knife can fully stir the material between the inner wall of the sleeve, break up the bubbles generated inside, and at the same time increase the heating rate of the material.

The gas extrusion and ejection can prevent the nylon carbon fiber from adhering to the inside of the sleeve.

[0020] S4: When the nylon carbon fiber enters the rotating discharge barrel for extrusion and is formed through the discharge port, the rotating shaft drives the connecting column to rotate, and the connecting column drives the inclined rotating plate to rotate, so that the extrusion column squeezes the jet column, so that air pressure is generated inside the jet column, and the gas is ejected through the outlet to dissipate heat for the formed nylon carbon fiber.

[0021] The present invention has the following beneficial effects:

[0022] 1. A high-efficiency hot melt extrusion device for nylon carbon fiber and its extrusion process. When extruding nylon carbon fiber, the nylon carbon fiber is heated from the feeding barrel to become a molten state. The servo motor drives the belt to move, and the belt drives the second transmission wheel to rotate. The second transmission wheel causes the rotating shaft to drive the spiral rotating plate to extrude and transport inside the sleeve. When the rotating shaft rotates, it can drive the rotating plate to rotate, so that the teeth on the rotating plate and the driven gear are engaged and transmitted. When the driven gear passes between the scalloped plate and the teeth, the driven gear can drive the rotating rod to rotate in the opposite direction, so that the stirring scraping knife fully stirs the material between the inner wall of the sleeve, breaks up the bubbles generated inside, and at the same time improves the heating rate of the material to prevent it from being heated unevenly.

[0023] 2. A high-efficiency hot melt extrusion device for nylon carbon fiber and its extrusion process. When the spiral rotating plate rotates, the side wall of the spiral rotating plate squeezes the transmission connecting rod, and the transmission connecting rod reciprocates through the reset spring, so that the transmission connecting rod can scrape the nylon carbon fiber on the spiral rotating plate. The transmission connecting rod rises through the sleeve and can clean the nylon carbon fiber attached to itself at the end of the scraping to prevent it from adhering to the spiral rotating plate and being detrimental to the next processing.

[0024] 3. A high-efficiency hot-melt extrusion device for nylon carbon fiber and its extrusion process. The transmission connecting rod rises to extrude the sealing sleeve, and the gas is stored inside the expansion airbag. When the transmission connecting rod moves to a certain position, the movable hole is connected with the connecting hole and the air injection hole, so that the gas stored in the expansion airbag can enter the sleeve, thereby effectively preventing the mother material heated and melted into a liquid state in the inner cavity of the sleeve from flowing back due to extrusion. The gas extrusion and ejection can prevent the nylon carbon fiber from adhering to the inside of the sleeve.

[0025] A high-efficiency hot melt extrusion device for nylon carbon fiber and its extrusion process. The nylon carbon fiber is extruded into a rotating discharge barrel and formed through a discharge port. The rotating shaft drives the connecting column to rotate, which drives the inclined rotating plate to rotate, so that the extrusion column squeezes the jet column, generating air pressure inside the jet column. The gas is ejected through the outlet to dissipate heat from the formed nylon carbon fiber.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

6. A high-efficiency hot melt extrusion process for nylon carbon fiber, characterized in that: The steps include: S1: When the nylon carbon fiber is extruded, the nylon carbon fiber is heated from the feeding barrel to be molten, the servo motor (201) drives the belt (202) to move, the belt (202) drives the second transmission wheel (203) to rotate, and the second transmission wheel (203) causes the rotating shaft (204) to drive the spiral rotating plate (205) to extrude and transport inside the sleeve. When the rotating shaft (204) rotates, it can drive the rotating plate (301) to rotate, so that the teeth (302) on the rotating plate (301) and the driven gear (303) are meshed and transmitted. When the driven gear (303) passes between the scalloped plate (304) and the teeth (302), the driven gear (303) can drive the rotating rod (305) to rotate in the opposite direction, so that the stirring scraping knife (306) fully stirs the material between the inner wall of the sleeve, breaks up the bubbles generated inside, and at the same time increases the heating rate of the material; S2: When the spiral rotating plate (205) rotates, the side wall of the spiral rotating plate (205) squeezes the transmission connecting rod (404), and the transmission connecting rod (404) reciprocates through the return spring (409), so that the transmission connecting rod (404) can scratch the nylon carbon fiber on the spiral rotating plate (205). The transmission connecting rod (404) rises through the sleeve and can clean the nylon carbon fiber attached to itself at the end of the scratching, so as to prevent it from adhering to the spiral rotating plate (205) and hindering the next processing; S3: The transmission connecting rod (404) rises to squeeze the sealing sleeve (408), and the gas is stored inside the expansion airbag (502). When the transmission connecting rod (404) moves to a certain position, the movable hole (504) is connected with the connecting hole (503) and the air injection hole (505), so that the gas stored in the expansion airbag (502) can enter the sleeve, thereby effectively preventing the mother material heated and melted into a liquid state in the inner cavity of the sleeve from flowing back due to squeezing. The gas squeezing and ejecting can prevent the nylon carbon fiber from adhering to the inside of the sleeve; S4: When the nylon carbon fiber enters the rotating discharge barrel (602) for extrusion and is formed through the discharge port (606), the rotating shaft (204) drives the connecting column (603) to rotate, so that the connecting column (603) drives the inclined plate (710) to rotate, so that the extrusion column (707) squeezes the jet column (703), so that air pressure is generated inside the jet column (703), and the gas is ejected through the outlet hole (704), thereby dissipating heat from the formed nylon carbon fiber.
