Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example Please see Figures 1-5 The present invention provides a high-precision nylon heat insulation strip extrusion and traction integrated machine, including a frame 10, an extruder 20, a feeding bin 30 and a bracket 40, a traction guide mechanism 50 and a heat insulation strip guide mechanism 60.

[0021] The system utilizes the cooperation of the frame 10, extruder 20, feeding hopper 30, bracket 40, traction guide mechanism 50, and heat insulation strip guide mechanism 60 to achieve stable output of nylon heat insulation strips extruded and processed by the extruder 20, avoid mutual compression of the extruded materials, and improve the forming quality of the heat insulation strips.

[0022] A bracket 40 is disposed at one end of the frame 10, an extruder 20 is mounted above the frame 10, and a feeding hopper 30 is installed at the feed inlet of the extruder 20. The traction guide mechanism 50 includes a first side plate 510, a second side plate 520, traction guide rollers 530, a gear set 540, and a motor 550. The first side plate 510 and the second side plate 520 are respectively fixed on both sides above the bracket 40. Multiple traction guide rollers 530 are rotatably disposed between the first side plate 510 and the second side plate 520. The motor 550 is mounted on the side of the first side plate 510, and the gear set 540 connects the end of the traction guide rollers 530 and the output shaft end of the motor 550. The heat insulation strip guiding mechanism 60 includes a front support 610, a rear support 620, a placement plate 630, and a front guide assembly 640. The front support 610 and the rear support 620 are respectively fixed at both ends above the bracket 40. The multi-layer traction guide roller 530 is arranged between the front support 610 and the rear support 620. The front guide assembly 640 is installed at the front end of the front support 610 and works with the traction guide roller 530 to pull the nylon heat insulation strip out.

[0023] Granular raw materials are added from the feeding hopper 30 into the extruder 20 and extruded to form nylon heat insulation strips. Multiple sets of nylon heat insulation strips extruded by the extruder 20 are layered and positioned above the traction guide roller 530. The motor 550 drives the traction guide roller 530 to rotate through the gear set 540, gradually conveying the formed nylon heat insulation strips to the front guide assembly 640 and the placement plate 630 in the heat insulation strip guiding mechanism 60. Layered guiding reduces the pressure on the bottom nylon heat insulation strips and improves the overall forming quality of the nylon heat insulation strips.

[0024] The high-precision nylon thermal insulation strip extrusion and traction integrated machine also includes a feeding and dust removal mechanism 70, which includes a dust collection box 710, a guide pipe 720, a negative pressure fan 730, and a screen 740. The screen 740 is located inside the feeding hopper 30. The two ends of the guide pipe 720 are respectively connected to the screen 740 and the dust collection box 710. The negative pressure fan 730 is installed in conjunction with the guide pipe 720.

[0025] Dust from the granular raw materials added to the feeding hopper 30 enters the dust collection box 710 through the mesh cover 740 and the guide pipe 720 when the negative pressure fan 730 is running. The dust collection box 710 completes the collection of dust from the raw materials, reducing dust during feeding and improving the molding quality of the nylon heat insulation strip.

[0026] Furthermore, the feeding and dust removal mechanism 70 also includes a support plate 750, which is fixedly connected to the guide pipe 720. An installation port 760 is provided at the end of the support plate 750 away from the guide pipe 720, and the installation port 760 is fixedly installed in conjunction with the bottom outer wall of the feeding hopper 30. The support plate 750 enhances the stability when supporting the guide pipe 720, which penetrates the side wall of the feeding hopper 30.

[0027] Specifically, the dust collection box 710 includes a box body 711 and a filter screen 712. The top of the box body 711 is connected to the bottom of the guide pipe 720, and the filter screen 712 is located at the air outlet at the top of the box body 711. The filter screen 712 blocks dust inside the box body 711, and the box body 711 is used to collect dust from the raw materials.

[0028] In the above specific embodiment, the front guiding assembly 640 includes a guiding plate 641 and a first side guard plate 642. One end of the guiding plate 641 is fixedly connected to the end of the placement plate 630, and the two first side guard plates 642 are respectively arranged on both sides above the guiding plate 641. The guiding plate 641 and the first side guard plate 642 in the front guiding assembly 640 are used for guiding the nylon heat insulation strip.

[0029] Furthermore, the heat insulation strip guiding mechanism 60 also includes a second side guard plate 650, with two second side guard plates 650 respectively disposed on both sides above the placement plate 630; the second side guard plates 650 are provided to prevent the heat insulation strip from falling off the side of the placement plate 630.

[0030] In its specific configuration, the traction guide roller 530 includes a roller shaft 531 and an anti-slip sleeve 532. The anti-slip sleeve 532 is fixedly fitted onto the outside of the roller shaft 531, and both ends of the roller shaft 531 are rotatably engaged with the first side plate 510 and the second side plate 520, respectively. The anti-slip sleeve 532 has several anti-slip grooves distributed along its axial direction on its outer surface. Both the anti-slip sleeve 532 and the anti-slip grooves are designed to increase the friction between the traction guide roller 530 and the heat insulation strip, reduce traction slippage, and improve stability during traction.

[0031] Specifically, the gear set 540 includes a driving gear, a first driven gear, a second driven gear, and a rotating shaft. The rotating shaft is rotatably mounted on the first side plate 510.

The driving gear is fixedly sleeved on the output shaft end of the motor 550. The driving gear, the first driven gear, and the second driven gear mesh with each other.

[0032] It should be noted that the specific models and specifications of the motor 550 and negative pressure fan 730 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be described in detail here. The power supply and principle of the motor 550 and negative pressure fan 730 are clear to those skilled in the art, and will not be described in detail here.

[0033] The working principle of this high-precision nylon thermal insulation strip extrusion and traction integrated machine is as follows: During operation, granular raw materials are added from the feeding hopper 30 into the extruder 20 and extruded to form nylon thermal insulation strips. Multiple sets of nylon thermal insulation strips extruded by the extruder 20 are layered and positioned above the traction guide roller 530. The motor 550 drives the traction guide roller 530 to rotate via the gear set 540, gradually conveying the formed nylon thermal insulation strips to the front guide assembly 640 and the placement plate 630 in the thermal insulation strip guiding mechanism 60. Layered guiding reduces the pressure on the bottom nylon thermal insulation strips, improving the overall forming quality of the nylon thermal insulation strips. Dust in the granular raw materials added to the feeding hopper 30 enters the dust collection box 710 through the mesh cover 740 and the guide pipe 720 when the negative pressure fan 730 is running. The dust collection box 710 collects the dust in the raw materials, reducing dust during feeding and improving the forming quality of the nylon thermal insulation strips.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
