Description

Technical Field

[0001] This utility model relates to the field of card protector film processing technology, specifically a horizontal flipping mechanism for card protector film. Background Technology

[0002] Card protector film, also known as shrink wrap, is a high-grade sheet packaging material made from a plastic film as a base, with adhesive coated on the back, and then processed specially. In the production and packaging process, equal quantities of card protector film need to be packaged in bags, then sealed with adhesive. These sealed bags are then divided into one or more bags and placed into cartons. When sealing equal quantities of card protector film in bags, whether by hand or automatic sealing, the adhesive side is always on the front of the seal. Because the front of the seal has sealing edges with adhesive, the bag containing the card protector film must be turned inside out during the next carton packaging step. Otherwise, the sealing edges and adhesive can easily stick to the carton's sealing edges, preventing the carton from sealing properly and potentially damaging the carton's seal on automated packaging machines.

[0003] The existing horizontal flipping mechanism for card protection film does not fix the card protection film bag during the flipping process, which causes it to shift during the flipping process, resulting in inconsistent landing point and angle. This requires manual secondary adjustment, which is cumbersome. Therefore, a new horizontal flipping mechanism for card protection film is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a horizontal flipping mechanism for protective film, including a fixed frame 1 and a flipping plate 7. Two fixed frames 1 are provided and are respectively placed on both sides of the flipping plate 7. A shaft tube 19 is installed at both ends of the flipping plate 7 and is rotatably connected to the fixed frame 1 through the shaft tube 19. An electric push rod 6 is installed at the end of one of the fixed frames 1. An adjusting rod 5 is connected to the power output end of the electric push rod 6. A limit plate 4 is fixed at the front end of the adjusting rod 5. An adjusting plate 2 is fixedly installed on the side wall of the limit plate 4. An adjusting hole 17 is opened on the inner side of the fixed frame 1 and the adjusting plate 2 passes through the adjusting hole 17. A number of teeth 15 are evenly arranged on the top surface of the adjusting plate 2. A gear 16 is connected to the shaft tube 19 and the gear 16 meshes with the teeth 15. After the adjusting plate 2 is pushed by the electric push rod 6, the gear 16 is driven to rotate through the teeth 15 on the surface of the adjusting plate 2. After the gear 16 rotates, the flipping plate 7 is driven to rotate through the shaft tube 19. The rotation angle can be adjusted according to the usage requirements.

[0021] Further improvements include an air pump 3 mounted on the outer wall of one of the mounting brackets 1, and a vacuum pump mounted on the outer wall of the other mounting bracket 1. The air pump 3 and the vacuum pump are connected to the ends of the shaft tube 19 via air guide plates 8. Baffles 11 are provided at both ends of the surface of the turning plate 7. The baffles 11 are L-shaped and form a positioning groove 12 with the turning plate 7. Several telescopic airbags 14 are evenly arranged at the top of the inner side of the positioning groove 12. Several adsorption holes 13 are evenly opened on the surface of the turning plate 7. The adsorption holes 13 and the telescopic airbags 14 are connected to the shaft tube 19, and the adsorption holes 13 are connected to the vacuum pump. The telescopic airbags 14 are connected to the air pump 3. After the air pump 3 outputs air, it is introduced into the telescopic airbags 14 through the shaft tube 19. After the telescopic airbags 14 extend, they fix the plastic bag. The vacuum pump evacuates the adsorption holes 13 to vacuum-adsorb and fix the plastic bag, improving the stability during the turning process.

[0022] Further improvements include mounting grooves 9 on both sides of the surface of the flipping plate 7, with guide rollers 10 rotatably connected inside the mounting grooves 9, which guide the plastic bags to be exported.

[0023] Further improvements include the uniform arrangement of several support wheels 18 at the bottom of the adjustment hole 17. The support wheels 18 are in close contact with the bottom of the adjustment plate 2, and the support wheels 18 support the adjustment plate 2, making the movement of the adjustment plate 2 more stable.

[0024] Working principle: After the protective film on the packaging line is packed into a plastic bag and sealed, it is fed onto the flipping plate 7. After the air pump 3 and vacuum pump are started, the telescopic airbag 14 extends and presses down on both sides of the plastic bag to fix it. After the suction hole 13 is evacuated, the tape is adsorbed. After the electric push rod 6 is started, it drives the adjusting plate 2 to move and drives the gear 16 to rotate. After the gear 16 rotates, it drives the flipping plate 7 to rotate. After the rotation is completed, the telescopic airbag 14 and the suction hole 13 are restored to their original state, and the plastic bag falls automatically, thus completing one flipping.

[0025] The components of this utility model are: 1. a fixed frame; 2. an adjusting plate; 3. an air pump; 4. a limiting plate; 5. an adjusting rod; 6. an electric push rod; 7. a turning plate; 8. an air guide plate; 9. a mounting groove; 10. a guide roller; 11. a baffle; 12. a positioning groove; 13. an adsorption hole; 14. a telescopic airbag; 15. teeth; 16. a gear; 17. an adjusting hole; 18. a support wheel; and 19. a shaft tube. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing horizontal turning mechanisms for protective film do not properly handle the protective film during the turning process. The traditional method of fixing the film-coated bags causes displacement during the flipping process, resulting in inconsistent landing points and angles. This necessitates manual re-adjustment, which is cumbersome. This invention addresses this issue through the combination of the aforementioned components. The flipping plate 7 is driven to rotate via gear 16 and a rack, ensuring stable flipping and adjustable angles. When the bag is placed on the flipping plate 7, it can be secured by negative pressure or by extending the telescopic airbag 14 to press down and fix the sides of the bag, improving stability during flipping and preventing displacement. The resulting bag placement and angle deviation are minimal, enhancing ease of use. The above description illustrates the basic principles, main features, and advantages of this invention. It is apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
