Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a pre-folding device for a box gluing machine. Background Art

[0002] Cartons are a commonly used packaging material, often used to transport and protect fragile items such as glassware, electronic products, and toys. Currently, carton production is primarily achieved through box gluing machines, which require a pre-folding device to glue the cardboard together.

[0003] After searching, the publication number CN213167102U is a pre-folding device for a box gluing machine. It is equipped with a water pump to transfer clean water from the water tank to the water supply brush position. The water supply brush moistens the circular brush, and the circular brush replenishes water at the indentation of the cardboard. This can prevent the cardboard from breaking during the indentation process, thereby reducing the scrap rate and improving the indentation efficiency.

[0004] However, the above technical solution requires adjustment of each of the multiple annular brushes one by one, as they are independent of each other. This results in a long overall adjustment time. Furthermore, after adjustment, the position of each annular brush needs to be debugged, resulting in poor overall convenience.

[0005] Based on this, we propose a pre-folding device for a box gluing machine. Utility Model Content

[0028] In detail, support holes are opened at both ends of the carrier 1, and the upper conveyor roller 2 and the lower conveyor roller 3 are connected inside the support holes through ball bearings. The setting of the support holes can effectively support the upper conveyor roller 2 and the lower conveyor roller 3, and the setting of the ball bearings can ensure the smooth rotation of the upper conveyor roller 2 and the lower conveyor roller 3;

[0029] The indentation assembly 6 includes an assembly frame 8, a transmission pipe 9, a liquid separation pipe 10 and a liquid guide pipe 11. Assembly frames 8 are provided at both ends of the inner side of the carrier frame 1. One end of the inner side of the assembly frame 8 is fixedly connected to the transmission pipe 9. The outer side of the transmission pipe 9 is fixedly connected to two liquid separation pipes 10. One end of the two liquid separation pipes 10 is rotatably connected to the liquid guide pipe 11. The outer side of the liquid guide pipe 11 is fixedly connected to a wetting ring 12 through a bracket. The outer side of the liquid guide pipe 11 is fixedly connected to a liquid supply pipe 13, and the end of the liquid supply pipe 13 away from the liquid guide pipe 11 is connected to the wetting ring 12. The other end of the inner side of the assembly frame 8 is rotatably connected to two indentation wheels 15. The top of the carrier frame 1 is fixedly connected to a liquid supply main pipe 17. Both ends of the outer side of the liquid supply main pipe 17 are fixedly connected to a transmission hose 18, and the ends of the two transmission hoses 18 away from the liquid supply main pipe 17 are respectively connected to the top of the two transmission pipes 9;

[0030] Furthermore, a moisture absorbing plate 14 is fixedly connected to the inner side of the wetting ring 12. The moisture absorbing plate 14 is made of cotton. The moisture absorbing plate 14 can absorb the liquid provided by the liquid supply pipe 13 and apply the liquid to the cardboard when the wetting ring 12 rotates.

[0031] Preferably, both ends of the top of the carrier frame 1 are fixedly connected to an extension frame 16, and the liquid supply pipe 17 is fixedly connected between the two extension frames 16. By using the setting of the extension frame 16, the liquid supply pipe 17 can be effectively assembled to ensure the stability of the application of the liquid supply pipe 17;

[0032] Furthermore, two water-absorbing plates are fixedly connected to the other end of the inner side of the assembly frame 8 to absorb the moisture from the pre-folded cardboard.

[0033] Example 2

[0034] like Figures 1 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes an adjustment component 7;

[0035] In this embodiment, the adjustment component 7 includes a central shaft 19, a threaded segment 20, a displacement frame 21 and a transmission motor 22. The bottom end of the inner side of the carrier frame 1 is rotatably connected to the central shaft 19. Both ends of the outer side of the central shaft 19 are provided with threaded segments 20, and the thread rotation directions of the two threaded segments 20 are opposite. The outer sides of the two threaded segments 20 are threadedly connected to the displacement frame 21, and the two assembly frames 8 are respectively fixedly connected to the top ends of the two displacement frames 21. The bottom of one end of the carrier frame 1 is fixedly connected to the transmission motor 22, and the output end of the transmission motor 22 is fixedly connected to the central shaft 19.

[0036] Here, a stabilizing seat is fixedly connected to the middle of the inner side of the carrier 1, and the central shaft 19 is also rotatably connected to the top of the stabilizing seat. The setting of the stabilizing seat can provide auxiliary support for the central shaft 19 to prevent the central shaft 19 from shaking;

[0037] Among them, linear slide rods are fixedly connected to both sides of the carrier frame 1, and the two displacement frames 21 are slidably connected to the outside of the linear slide rods. The setting of the linear slide rods can effectively guide the displacement of the displacement frame 21 to prevent the displacement frame 21 from rotating with the central axis 19.

[0038] A specific application of the above two embodiments is as follows: first, the external liquid pipeline is connected to the liquid supply main pipe 17, and then the cardboard for the carton is passed through the two wetting rings 12, between the upper conveyor roller 2 and the lower conveyor roller 3, and between the two creasing wheels 15 in sequence, and the conveying motor 5 is started to drive the upper conveyor roller 2 to rotate. With the arrangement between the two linked spur gears 4, the power of the upper conveyor roller 2 can be transmitted to the lower conveyor roller 3, prompting the lower conveyor roller 3 to rotate accordingly. Since the cardboard is located between the upper conveyor roller 2 and the lower conveyor roller 3, the cardboard can be conveyed;

[0039] The liquid in the liquid supply main 17 is sent to the two transmission pipes 9 through the transmission hose 18, and is introduced into the liquid guide pipe 11 through the liquid distribution pipe 10. Finally, it is injected into the moisture absorption plate 14 through the liquid supply pipe 13 to moisten the moisture absorption plate 14. When the cardboard passes through the moisture absorption plate 14, it can carry away the liquid at the moisture absorption plate 14, moistening the pre-folding position of the cardboard. The moistened cardboard will be indented by the creasing wheel 15, thereby forming a pre-folding process for the cardboard.

[0040] The transmission motor 22 can be started to drive the central shaft 19 to rotate. In conjunction with the arrangement of the two threaded sections 20 with opposite thread rotation directions, the position of the assembly frame 8 can be changed by the relative displacement of the two displacement frames 21, thereby adjusting the distance between the two assembly frames 8 to accommodate cardboards of different widths.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
