Description
An integrated feeding mechanism for PVC light film processing Technical Field
[0001] This utility model relates to the field of PVC light film processing technology, specifically to an integrated feeding mechanism for PVC light film processing. Background Technology
[0002] When decorating indoor and outdoor spaces, people often apply PVC light-emitting film to the lighting systems to meet their lighting needs. However, the processing of PVC light-emitting film requires adding PVC powder to production equipment (such as mixing equipment). This powder may contain clumps of raw material, and directly adding these clumps to the production equipment will affect the mixing process and thus the quality of the PVC light-emitting film. Summary of the Invention
[0003] To address the problems in the existing technology, this utility model provides an integrated feeding mechanism for PVC light film processing.
[0004] The technical solution adopted by this utility model to solve its technical problem is an integrated feeding mechanism for PVC light film processing, including a feeding box missing at the bottom. A cover plate is fixed to the top of the feeding box, and a feeding hopper is fixed to the cover plate. A motor is fixed to one side of the feeding box. The feeding box is equipped with a first crushing roller, a second crushing roller, a baffle, and an inclined outer frame. One end of the first crushing roller is connected to the output shaft of the motor through a coupling, and one end of the second crushing roller is rotatably connected to the feeding box. Gears are fixed to the ends of the first and second crushing rollers away from the motor. Two gears mesh with each other. Both sides of the baffle are connected to the feeding box. The baffle is located above the first crushing roller. A screen is fixed inside the outer frame. The outer frame has a through hole. A connecting rod is installed in the through hole. Both ends of the connecting rod are connected to the feeding box. Multiple support pillars are fixed on the outer frame. Each support pillar is fitted with a spring. A base and a notch are provided on one side of the feeding box. The notch is penetrating on the side of the outer frame away from the baffle. The base is connected to the feeding box. A crossbar is rotatably connected inside the base. A lever is fixed on the crossbar. A pulley is fixed to the end of the crossbar and the first crushing roller. The two pulleys are connected by a belt.
[0005] By adopting the above technical solution, the output shaft of the motor drives the first crushing roller to rotate, and the cooperation of the two gears causes the second crushing roller to rotate accordingly. The first crushing roller, the pulley on the crossbar, and the belt cause the crossbar to rotate as well. When the crossbar rotates, the deflector plate collides with the outer frame, and the outer frame and screen vibrate, which is beneficial for screening PVC powder and rolling of agglomerated raw materials. The first and second crushing rollers can crush agglomerated raw materials, and the crushed raw materials are discharged from the bottom of the feeding box, thereby preventing agglomerated raw materials from falling into the production equipment.
[0006] Specifically, the feeding box has two detachably connected cleaning brushes, with the first crushing roller and the second crushing roller located between the two cleaning brushes.
[0007] By adopting the above technical solution, when the first crushing roller and the second crushing roller rotate, the two cleaning brushes can clean the raw materials attached to the first crushing roller and the second crushing roller, preventing the raw materials from adhering to the first crushing roller and the second crushing roller.
[0008] Specifically, the feeding box has an observation port on the side away from the motor, and the observation port is equipped with glass.
[0009] By adopting the above technical solution, the inside of the feeding box can be easily observed through the observation port and glass.
[0010] Specifically, the bottom of the feeding box is provided with two support mechanisms, each of which includes a support, a limiting bolt, and a base. The top of the support is connected to the feeding box, and the top of the base is provided with a groove that matches the support. One side of the base is provided with two screw holes that match the limiting bolt, and one side of the support is provided with multiple slots that match the limiting bolt.
[0011] By adopting the above technical solution, loosening the limiting bolt, moving the feeding box upward, and screwing the end of the limiting bolt into the slot on the side wall of the support, the height of the feeding box can be adjusted as needed.
[0012] Specifically, mounting holes are provided at the four corners of the bottom of the base.
[0013] By adopting the above technical solution, the mounting holes are designed to facilitate the use of bolts to fix the base to the production equipment.
[0014] The beneficial effects of this utility model are:
[0015] (1) The integrated PVC light film processing feeding mechanism of this utility model has a motor output shaft that drives the first crushing roller to rotate. The cooperation of two gears causes the second crushing roller to rotate accordingly. The first crushing roller, the pulley on the crossbar, and the belt cause the crossbar to rotate. When the crossbar rotates, the deflector plate collides with the outer frame, and the outer frame and screen vibrate, which is beneficial to the screening of PVC powder and the rolling of agglomerated raw materials. The first crushing roller and the second crushing roller can crush the agglomerated raw materials. The crushed raw materials are discharged from the bottom of the feeding box, thereby preventing the agglomerated raw materials from falling into the production equipment.
[0016] (2) The integrated PVC light film processing feeding mechanism of this utility model can be adjusted as needed by loosening the limiting bolt, moving the feeding box upward, and screwing the end of the limiting bolt into the slot on the side wall of the support. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] To prevent agglomerated raw materials from entering the production equipment, as an embodiment of this utility model, as shown in Figures 1, 2, and 3, the integrated PVC light film processing feeding mechanism of this utility model includes a feeding box 1 with a missing bottom end. A cover plate 6 is bolted to the top of the feeding box 1, and a feed hopper 7 is welded to the cover plate 6. A motor 2 is bolted to one side of the feeding box 1. The feeding box 1 contains a first crushing roller 15, a second crushing roller 16, a baffle 19, and an inclined outer frame 21. One end of the first crushing roller 15 is connected to the output shaft of the motor 2 via a coupling, and one end of the second crushing roller 16 is rotatably connected to the feeding box 1. Gears 13 are fixed to the ends of both the first crushing roller 15 and the second crushing roller 16 away from the motor 2. The wheels 13 mesh with each other. Both sides of the baffle 19 are welded to the feed box 1. The baffle 19 is located above the first crushing roller 15. The screen 20 is fixed inside the outer frame 21 by bolts. The outer frame 21 has a through hole. The through hole has a connecting rod 18. The connecting rod 18 is not fixed to the outer frame 21. Both ends of the connecting rod 18 are welded to the feed box 1. Multiple support pillars 22 are welded to the outer frame 21. Each support pillar 22 is fitted with a spring 23. The feed box 1 has a base 10 and a notch on one side. The notch is passed through the side of the outer frame 21 away from the baffle 19. The base 10 is welded to the feed box 1. A crossbar 8 is rotatably connected inside the base 10. A lever 80 is welded to the crossbar 8. The ends of the crossbar 8 and the first crushing roller 15 are both fixed with pulleys 9. The two pulleys 9 are connected by a belt 11.
[0024] In use, the output shaft of motor 2 drives the first crushing roller 15 to rotate. The cooperation of the two gears 13 causes the second crushing roller 16 to rotate accordingly. The setting of the first crushing roller 15 with the pulley 9 and belt 11 on the crossbar 8 causes the crossbar 8 to rotate as well. When the crossbar 8 rotates, the deflector 80 collides with the outer frame 21, and the outer frame 21 and the screen 20 vibrate. After the raw material is put into the feeding box 1 through the feed hopper 7, the vibrating screen 20 is conducive to the screening of PVC powder and the rolling of agglomerated raw materials. The first crushing roller 15 and the second crushing roller 16 can crush the agglomerated raw materials. The crushed raw materials are discharged from the bottom of the feeding box 1 and fall into the production equipment, realizing feeding and thus preventing agglomerated raw materials from falling into the production equipment.
[0025] To facilitate the cleaning of the first crushing roller 15 and the second crushing roller 16, for example, as shown in Figure 2, two cleaning brushes 17 are detachably connected inside the feeding box 1. Both cleaning brushes 17 are connected to the feeding box 1 by bolts, and the first crushing roller 15 and the second crushing roller 16 are located between the two cleaning brushes 17.
[0026] During use, the first crushing roller 15 and the second crushing roller 16 rotate, and the two cleaning brushes 17 can clean the raw materials adhering to the first crushing roller 15 and the second crushing roller 16 to prevent the raw materials from adhering to the first crushing roller 15 and the second crushing roller 16.
[0027] To facilitate observation of the interior of the feeding box 1, as exemplarily shown in Figure 1, the feeding box 1 is provided with an observation port on the side away from the motor 2, and a glass 12 is provided inside the observation port. The glass 12 is connected to the feeding box 1 by an adhesive.
[0028] To facilitate the adjustment of the height of the feeding box 1, as exemplarily shown in Figure 1, the bottom end of the feeding box 1 is provided with two support mechanisms 14. The support mechanism 14 includes a support 3, a limiting bolt 4, and a base 5. The top end of the support 3 is welded to the feeding box 1. The top end of the base 5 is provided with a groove that matches the support 3. One side of the base 5 is provided with two screw holes that match the limiting bolt 4. One side of the support 3 is provided with multiple slots that match the limiting bolt 4.
[0029] When in use, loosen the limit bolt 4, move the feeding box 1 upward, and screw the end of the limit bolt 4 into the slot on the side wall of the support 3. The height of the feeding box 1 can be adjusted as needed.
[0030] To facilitate the fixing of the base 5, as exemplarily shown in Figure 1, mounting holes are provided at the four corners of the bottom end of the base 5.
[0031] When in use, place the base 5 on the production equipment (existing technology, not shown), fix the base 5 on the production equipment with bolts, loosen the limit bolt 4, move the feeding box 1 up, and screw the end of the limit bolt 4 into the slot on the side wall of the support 3. The height of the feeding box 1 and the feeding hopper 7 can be adjusted as needed.
[0032] The output shaft of motor 2 drives the first crushing roller 15 to rotate. The cooperation of two gears 13 causes the second crushing roller 16 to rotate accordingly. The setting of the first crushing roller 15 with the pulley 9 and belt 11 on the crossbar 8 causes the crossbar 8 to rotate as well. When the crossbar 8 rotates, the deflector 80 collides with the outer frame 21, causing the outer frame 21 and the screen 20 to vibrate. After the raw material is fed into the feeding box 1 through the feed hopper 7, the vibrating screen 20 facilitates the screening of PVC powder and the rolling of agglomerated raw materials. The first crushing roller 15 and the second crushing roller 16 can crush the agglomerated raw materials. The crushed raw materials are discharged from the bottom of the feeding box 1 and fall into the production equipment, realizing feeding and thus preventing agglomerated raw materials from falling into the production equipment.
