Description

Technical Field

[0001] This invention relates to the field of plastic processing, and more particularly to a color mixing device for slipper production. Background Technology

[0002] Slippers are injection molded from elastic plastic material. They are soft, comfortable, breathable, and slip-resistant. Some multi-colored slippers are produced by using a color mixing device to mix and inject two single-color molten plastic materials, thus creating multi-colored slippers.

[0003] In actual production, depending on style requirements, slippers often need to be made with mixed colors or two-tone designs. For two-tone slippers, two different colored molten rubber materials are required during injection molding, injected independently from the top and bottom of the mold. However, existing color mixing devices only have the function of mixing and injecting the two materials together, and cannot flexibly switch and adjust to achieve independent injection of two single-color molten rubber materials, making it difficult to meet the production needs of slippers.

[0006] Preferably, the front part of the second sealing disc is respectively provided with an injection piston and a sealing sleeve. The injection piston is slidably engaged with the second sealing disc, and the sealing sleeve is fixedly connected to the second sealing disc. The two material cylinders at the front are respectively aligned with the injection piston and the sealing sleeve. A stirring shaft is slidably installed through the middle of the sealing sleeve. Three stirring blades extend in a ring array from one end of the stirring shaft. The sealing sleeve is slidably installed on the outer surface of the stirring blades. A carrier plate is slidably installed on the outer surface of the stirring shaft. Three sealing plates extend in a ring array from the side of the carrier plate. The sealing plates are pressed against the side of the stirring blades. The sealing sleeve is slidably installed on the outer surface of the sealing plates. The carrier plate is elastically connected to the second sealing disc. A color mixing injection tube is fixedly connected to the front part of the first sealing disc.

[0007] Preferably, two cylinder supports are fixedly installed on the side of the second sealing disc.

A piston support is fixedly installed at the output end of the second servo pusher cylinder, and the end of the piston support is fixed to the injection piston. A support frame is fixedly installed at the output end of the third servo pusher cylinder. The support frame is slidably connected to one of the cylinder supports. A second servo motor is fixedly installed at one end of the support frame. The other end of the stirring shaft is rotatably connected to the other end of the support frame.

[0008] Preferably, a first servo motor is fixedly installed at the lower end of the second sealing disc, and a gear is coaxially fixedly installed at the output end of the first servo motor, the gear meshing with the shifting gear disc.

[0009] Preferably, a guide post is slidably mounted through the end of the carrier disk, one end of the guide post is fixed to the second sealing disk, and a push spring is wound around the outside of the guide post, with both ends of the push spring fixed to the other end of the carrier disk and the other end of the guide post, respectively.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The moving control frame moves the control plug downwards, aligning the through-hole on the control plug with the first single-color injection tube and sealing the connecting pipe. This allows the single-color molten adhesive in the upper screw injection barrel to be injected directly from the first single-color injection tube. Simultaneously, the moving control frame, via the connecting frame, moves the sealing slide forward, aligning the second single-color injection tube with the lower screw injection barrel. This allows the other single-color molten adhesive in the lower screw injection barrel to be injected directly from the second single-color injection tube. This allows the two single-color molten adhesives to be injected from the upper and lower ends of the slipper mold respectively. The injection process creates two-tone slippers. When the control frame moves in the opposite direction, causing the control plug to move upward, it seals the first single-color injection tube and opens the connecting tube, allowing the single-color molten rubber in the upper screw injection barrel to enter the lower screw injection barrel and mix with it. The mixed molten rubber is then injected from the color mixing injection tube, allowing it to enter the mold and form the mixed-color slippers. The injected molten rubber can be flexibly adjusted as needed, effectively meeting the production requirements of slippers.

[0012] 2. When the single-color molten adhesive in the upper screw injection barrel enters the lower screw injection barrel and mixes with the single-color molten adhesive in the lower screw injection barrel before being discharged, this portion of the molten adhesive will enter the barrel. Subsequently, servo motor number one drives the shifting gear plate to rotate, thereby shifting the barrel so that the barrel containing the molten adhesive is positioned at the sealing sleeve. At this time, servo cylinder number three pushes the support frame to move laterally, allowing the stirring blades on the stirring shaft to extend from the sealing sleeve and enter the barrel. Simultaneously, servo motor number two drives the stirring shaft... The agitator rotates to agitate the molten rubber in the barrel, ensuring thorough color mixing. Then, the first servo motor drives the shifting gear to rotate again, repositioning the barrel so that the barrel containing the agitated molten rubber is positioned at the injection piston. Subsequently, the second servo pusher cylinder moves the injection piston to the side, pushing the molten rubber in the barrel and injecting it from the color mixing injection tube. This cycle is repeated to ensure thorough mixing of the two single-color molten rubbers, thereby improving the color mixing effect of the molten rubber. Attached Figure Description

[0015] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figures 1-8The illustrated color mixing device for slipper production includes a lower screw injection cylinder 1 and an upper screw injection cylinder 2. Both the lower screw injection cylinder 1 and the upper screw injection cylinder 2 eject molten adhesive through their internal screws. A connecting pipe 3 is fixedly connected to the end of the upper screw injection cylinder 2, and the lower end of the connecting pipe 3 is fixedly connected to the lower screw injection cylinder 1. The connecting pipe 3 allows the single-color molten adhesive in the upper screw injection cylinder 2 to enter the lower screw injection cylinder 1. A single-color injection tube 8 is fixedly connected to the side of the connecting pipe 3. A control plug 16 is slidably installed inside the connecting pipe 3, and the upper end of the control plug 16 extends through the top of the connecting pipe 3. 6 controls the opening and closing of the first single-color injection tube 8 and the connecting tube 3. A second sealing disc 10 is fixedly connected to the side of the lower screw injection cylinder 1. A first sealing disc 9 is coaxially arranged to the side of the second sealing disc 10. A sealing slide plate 29 is slidably installed through the rear end of the first sealing disc 9. A second single-color injection tube 30 is fixedly connected to the side of the sealing slide plate 29. The sealing slide plate 29 can both block the cylinder 12 and change the position of the second single-color injection tube 30. A control frame 4 is fixedly installed at the upper end of the control plug 16. A connecting rod is rotatably installed between the lower end of the control frame 4 and the rear end of the sealing slide plate 29. A color mixing component is installed between the first sealing disc 9 and the second sealing disc 10 in the connecting frame 28. The control frame 4 moves the control plug 16 downwards, aligning the through hole on the control plug 16 with the first single-color injection tube 8, and sealing the connecting pipe 3. This allows the single-color molten adhesive in the upper screw injection cylinder 2 to be injected directly from the first single-color injection tube 8. Simultaneously, the control frame 4, via the connecting frame 28, moves the sealing slide plate 29 forward, aligning the second single-color injection tube 30 with the lower screw injection cylinder 1, allowing another single-color molten adhesive in the lower screw injection cylinder 1 to be injected directly from the second single-color injection tube 30. This allows the two colors to be mixed. Single-color molten rubber is injected from the top and bottom of the slipper mold to form slippers of two colors. When the control frame 4 moves in the opposite direction and drives the control plug 16 to move upward, it will block the first single-color injection tube 8 and open the connecting tube 3, so that the single-color molten rubber in the upper screw injection barrel 2 can enter the lower screw injection barrel 1 and mix with the single-color molten rubber in the lower screw injection barrel 1. The mixed molten rubber is then injected from the color mixing injection tube 14, so that the mixed molten rubber enters the mold to form mixed-color slippers. The injected molten rubber can be flexibly adjusted as needed, effectively meeting the production needs of slippers.

[0017] A fixed frame 7 is fixedly installed at the rear end of the connecting pipe 3. The control frame 4 is slidably installed at the end of the fixed frame 7. A first servo push cylinder 6 is fixedly installed at the rear end of the fixed frame 7. The fixed frame 7 can support the first servo push cylinder 6 and guide the control frame 4. The output end of the first servo push cylinder 6 is fixed to the control frame 4. The first servo push cylinder 6 plays the role of driving the control frame 4 to move.

[0018] The color mixing component includes a fixing column 11 coaxially fixed between the first sealing disc 9 and the second sealing disc 10. The fixing column 11 serves to fix the first sealing disc 9 and the second sealing disc 10 together. A shifting gear disc 15 is coaxially rotatably mounted in the middle of the fixing column 11. Three material cylinders 12 are fixedly mounted in a ring array on the shifting gear disc 15. The shifting gear disc 15 serves to support the material cylinders 12. Sealing rings 38 are fixedly mounted at both ends of the material cylinders 12. The end face of the material cylinders 12 is flush with the sealing rings 38. The two sealing rings 38 are respectively pressed against the opposite faces of the first sealing disc 9 and the second sealing disc 10. The sealing slide plate 29 is pressed against the sealing rings 38. Air holes can be opened in the area of ​​the sealing slide plate 29 relative to the material cylinders 12 so that when the single-color molten rubber material in the subsequent lower screw injection cylinder 1 enters the material cylinder 12, the air in the material cylinder 12 can be smoothly discharged. The end of the material cylinder 12 is aligned with the end of the lower screw injection cylinder 1.

[0019] An injection piston 23 and a sealing sleeve 21 are respectively installed through the front part of the second sealing disc 10. The injection piston 23 is slidably engaged with the second sealing disc 10, and the sealing sleeve 21 is fixedly connected to the second sealing disc 10. The two material cylinders 12 at the front are aligned with the injection piston 23 and the sealing sleeve 21 respectively. The injection piston 23 can push the molten rubber in the material cylinder 12. A stirring shaft 22 is slidably installed through the middle of the sealing sleeve 21. Three stirring blades 31 extend in a ring array at one end of the stirring shaft 22. The stirring shaft 22 serves to support the stirring blades 31. The sealing sleeve 21 is slidably installed on the outer surface of the stirring blades 31. The stirring blades 31 can agitate the molten rubber in the material cylinder 12 to make it fully mixed. A carrier plate 19 is slidably installed on the outer surface of the stirring shaft 22. A ring array extends from the side of the carrier plate 19. There are three sealing plates 20. The carrier plate 19 supports the sealing plates 20. The sealing plates 20 are pressed against the side of the stirring plate 31. The sleeve 21 is slidably installed on the outer surface of the sealing plates 20. The carrier plate 19 is elastically connected to the second sealing plate 10. When the stirring plate 31 extends out of the sleeve 21, the sealing plates 20 on the carrier plate 19 will slide inside the sleeve 21 under the action of elasticity to fill the inside of the sleeve 21 and prevent the single-color molten rubber from entering. The front of the first sealing plate 9 is fixedly connected to the color mixing injection tube 14. The color mixing injection tube 14 is aligned with the injection piston 23. The color mixing injection tube 14 is used to discharge the molten rubber in the barrel 12. One-way valves can be installed on the color mixing injection tube 14, the first single-color injection tube 8 and the second single-color injection tube 30 to allow the single-color molten rubber to flow out in one direction.

[0020] Two cylinder supports 33 are fixedly mounted on the side of the second sealing disc 10. A second servo pusher cylinder 34 and a third servo pusher cylinder 35 are fixedly mounted at the ends of the two cylinder supports 33 respectively. The cylinder supports 33 support the second servo pusher cylinder 34 and the third servo pusher cylinder 35. A piston support 37 is fixedly mounted at the output end of the second servo pusher cylinder 34. The end of the piston support 37 is fixed to the injection piston 23, and the piston support 37 connects to the injection piston 23. A support frame 5 is fixedly mounted at the output end of the third servo pusher cylinder 35. The support frame 5 is slidably connected to one of the cylinder supports 33, and one end of the support frame 5 is fixedly mounted with… There is a second servo motor 36. Under the control of the second servo motor 36, the stirring blade 31 can maintain its original angle when it stops rotating, so as to ensure that the stirring blade 31 can smoothly return to the sleeve 21. The other end of the stirring shaft 22 is rotatably connected to the other end of the support frame 5. The output end of the second servo motor 36 is fixed to the stirring shaft 22. The second servo motor 36 can drive the stirring blade 31 on the stirring shaft 22 to rotate. At the same time, the third servo push cylinder 35 drives the stirring blade 31 to move left and right, so as to use the rotating and moving stirring blade 31 to stir the molten rubber in the barrel 12, so as to fully mix it.

[0021] A servo motor 13 is fixedly installed at the lower end of the second sealing disc 10. A gear 32 is fixedly installed coaxially at the output end of the first servo motor 13. The gear 32 meshes with the shifting gear disc 15. The first servo motor 13 drives the shifting gear disc 15 to rotate through the gear 32, so as to shift the position of the material cylinder 12.

[0022] A guide post 17 is slidably mounted through the end of the carrier plate 19. One end of the guide post 17 is fixed to the second sealing plate 10. The guide post 17 serves as a guide. A push spring 18 is wound around the outside of the guide post 17. The two ends of the push spring 18 are fixed to the other end of the carrier plate 19 and the guide post 17, respectively. The push spring 18 serves to move the sealing plate 20 on the carrier plate 19 into the sealing sleeve 21.

[0023] A stepped hole 24 is provided through the side of the injection piston 23 near the edge. A cap rod 26 is inserted inside the stepped hole 24. A sealing cap 25 is coaxially fixed to one end of the cap rod 26. The cap rod 26 serves to support the sealing cap 25. The sealing cap 25 is pressed against the stepped surface of the stepped hole 24. A sealing spring 27 is wound around the outside of the cap rod 26. The sealing spring 27 serves to reset the sealing cap 25. When the injection piston 23 pushes out the molten rubber in the barrel 12 and moves back to reset, the sealing cap 25 will move sideways under the action of negative pressure, which will open the stepped hole 24 and allow a small amount of air to enter, so that the injection piston 23 can be reset smoothly. The two ends of the sealing spring 27 are fixed to the injection piston 23 and the other end of the cap rod 26, respectively.

[0024] During slipper production, when two-tone slippers are required, the first servo cylinder 6 drives the control frame 4 to move, causing the control plug 16 to move downwards. This aligns the through hole on the control plug 16 with the first single-color injection tube 8, and seals the connecting pipe 3, allowing the single-color molten adhesive in the upper screw injection cylinder 2 to be injected directly from the first single-color injection tube 8. Simultaneously, the moving control frame 4, via the connecting frame 28, drives the sealing slide plate 29 forward, aligning the second single-color injection tube 30 with the lower screw injection cylinder 1, allowing the other single-color molten adhesive in the lower screw injection cylinder 1 to be injected. The adhesive material is injected directly through the barrel 12 from the second single-color injection tube 30, allowing the two single-color molten adhesive materials to be injected from the upper and lower ends of the slipper mold respectively, forming slippers of two colors. When mixed-color slippers are needed, the first servo pusher cylinder 6 drives the control frame 4 to move in the opposite direction, which in turn drives the sealing slide plate 29 to move backward through the connecting frame 28, so that the sealing slide plate 29 blocks the barrel 12. At the same time, the reverse-moving control frame 4 also drives the control plug 16 to move upward to block the first single-color injection tube 8 and open the connecting pipe 3, so that the upper screw injection barrel 2... The single-color molten adhesive enters the lower screw injection barrel 1 and mixes with the single-color molten adhesive already in the lower screw injection barrel 1. It is then discharged into the barrel 12. Subsequently, servo motor 13 drives the shifting gear 15 via gear 32 to shift the position of barrel 12, positioning it at the sleeve 21. At this time, servo cylinder 35 pushes the support frame 5 to move laterally, allowing the agitator 31 on the agitator shaft 22 to extend from the sleeve 21 and enter the barrel 12. Simultaneously, servo motor 36 drives the agitator 22... The stirring blade 31 rotates to agitate the molten rubber in the barrel 12, ensuring thorough color mixing. Then, the first servo motor 13 drives the shifting gear 15 to rotate again via the gear 32, shifting the barrel 12 so that the barrel 12 containing the agitated molten rubber is positioned at the injection piston 23. Subsequently, the second servo pusher cylinder 34 drives the injection piston 23 to move laterally, pushing the molten rubber in the barrel 12 and injecting it out from the color mixing injection tube 14, thereby allowing the mixed molten rubber to enter the mold and form the mixed-color slippers.
