Description

Technical Field

[0001] This utility model relates to the field of paper cups, and more specifically, to a high-gloss offset printing mechanism for paper cups. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are shaped like cups. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. High-gloss offset printing on paper cups requires bright colors and a smooth surface.

[0003] For example, patent (CN222387785U) discloses a high-gloss offset printing mechanism for paper cups. The user inserts the paper cup into the front end of the placement rod, and controls the rotation of the turntable and the rubber roller inside the offset printing device through the control cabinet. When the placement rod rotates to the position of the rubber roller, the outer wall of the paper cup is attached to the rubber roller. The pattern is printed onto the outer wall of the paper cup by the rotation of the rubber roller. When the placement rod rotates to the bottom of the offset printing device, the user removes the paper cup and places it on the conveyor belt for conveying. The rotation of the turntable allows the equipment to print alternately without waiting, thus improving printing efficiency.

[0004] When using the above technology, the following technical problems were found in the existing technology: the rigidity of the spring causes the clamping force to be unable to be automatically adjusted according to the thickness of the cup wall. Excessive clamping force can easily deform the paper cup or even crush the cup body, while insufficient clamping force will cause the cup body to shift during the printing process, affecting the registration accuracy. To address this, we designed a high-gloss offset printing mechanism for paper cups to provide another technical solution to the above technical problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-8 A high-gloss offset printing mechanism for paper cups includes a bottom support plate 1, a vertical support plate 2 fixed to the top of the bottom support plate 1, a circular rotating disk 3 rotatably connected inside the vertical support plate 2, a plurality of horizontal rotating columns 8 rotatably connected inside the circular rotating disk 3, a fixing mechanism for fixing the paper cup is provided at one end of the horizontal rotating columns 8, and a rotating mechanism for rotating is provided at one end of the circular rotating disk 3.

[0033] The fixing mechanism includes a circular fixing block 17, which is fixed inside the transverse rotating column 8. A second transverse hydraulic cylinder 18 is fixed to one end of the circular fixing block 17. A circular moving plate 19 is fixed to the output end of the second transverse hydraulic cylinder 18. Multiple inclined rotating columns 20 are rotatably connected to the inner side of the circular moving plate 19. A circular sliding tube 22 is rotatably connected to one end of the inclined rotating column 20 through a pin. An inclined support block 10 is fixed to the end of the circular sliding tube 22 away from the circular fixing block 17. Multiple circular guide columns 21 are fixed to the outer side of the circular fixing block 17. The circular sliding tube 22 is sleeved on the outer side of the circular guide column 21 and slidably connected to the circular guide column 21.

[0034] The circular sliding tube 22 has a circular through groove inside. The circular guide post 21 and the circular sliding tube 22 are slidably connected through the circular through groove. The circular through groove allows the circular sliding tube 22 to slide on the outside of the circular guide post 21. The sliding of the circular sliding tube 22 allows the inclined support block 10 to move.

[0035] The interior of the transverse rotating column 8 is also equipped with a first transverse hydraulic cylinder 15. A circular push plate 16 is fixed to the output end of the first transverse hydraulic cylinder 15. Multiple L-shaped push plates 9 are fixed to the outside of the circular push plate 16. The L-shaped push plates 9 are located inside the transverse rotating column 8 and are slidably connected to the transverse rotating column 8. Through the operation of the first transverse hydraulic cylinder 15, the circular push plate 16 can move. The movement of the circular push plate 16 causes the L-shaped push plates 9 to move, thereby enabling the L-shaped push plates 9 to feed the paper cups on the outside of the inclined support block 10.

[0036] Here, the inner wall of the paper cup is placed on the outside of the inclined support block 10. Through the operation of the second transverse hydraulic cylinder 18, the circular moving plate 19 can be moved. The movement of the circular moving plate 19 is transmitted through the inclined rotating column 20, which allows the circular sliding tube 22 to move on the outside of the circular guide column 21, thereby enabling the multiple inclined support blocks 10 to fix the paper cup.

[0037] After the paper cup printing is completed, the operation of the first horizontal hydraulic cylinder 15 enables the circular push plate 16 to move. The movement of the circular push plate 16, through the L-shaped push plate 9, enables the paper cup to detach from the outside of the horizontal rotating column 8, so that the paper cup can be fed.

[0038] The rotating mechanism includes a first drive motor 6. The first drive motor 6 is bolted to one end of the circular rotating disk 3 away from the transverse rotating column 8. A second drive gear 12 is fixed to the output end of the first drive motor 6. Driven gears 13 are evenly distributed and meshed on the outer side of the second drive gear 12. The driven gears 13 are sleeved on the outer side of the transverse rotating column 8 and fixedly connected to the transverse rotating column 8. A circular fixing ring 14 is rotatably connected to one end of the transverse rotating column 8 near the circular rotating disk 3 through a bearing. The circular fixing ring 14 is located inside the circular rotating disk 3 and fixedly connected to the circular rotating disk 3.

[0039] A second drive motor 7 is bolted to one end of the vertical support plate 2. A first drive gear 11 is fixed to the output end of the second drive motor 7. The first drive gear 11 is meshed with the circular rotating disk 3. Through the operation of the second drive motor 7, the first drive gear 11 can rotate. The rotation of the first drive gear 11 is connected to the circular rotating disk 3 through meshing with the first drive gear 11, so that the circular rotating disk 3 can rotate inside the vertical support plate 2.

[0040] Multiple gear slots are evenly distributed on the outer side of the circular rotating disk 3. The first driving gear 11 and the circular rotating disk 3 are meshed and connected through the gear slots, so that the rotation of the first driving gear 11 can drive the circular rotating disk 3 to rotate inside the vertical support plate 2.

[0041] A printing box 4 is provided at one end of the top of the bottom support plate 1. A vertical plate 5 is provided on one side of the printing box 4. The bottom of the vertical plate 5 is fixedly connected to the bottom support plate 1. A longitudinal hydraulic cylinder 23 is provided at one end of the top of the vertical plate 5. A printing squeegee 24 is fixed at the output end of the longitudinal hydraulic cylinder 23. The printing box 4 and the printing squeegee 24 are connected by a pipe. The printing box 4 can provide printing adhesive to the printing squeegee 24. The printing squeegee 24 can move towards the outside of the paper cup through the longitudinal hydraulic cylinder 23.

[0042] Here, the operation of the first drive motor 6 enables the second drive gear 12 to rotate. The rotation of the second drive gear 12, through the meshing connection between the second drive gear 12 and the driven gear 13, enables multiple driven gears 13 to rotate, thereby causing the transverse rotating column 8 to rotate. The rotation of the transverse rotating column 8 enables the paper cup to rotate.

[0043] The operation of the second drive motor 7 enables the first drive gear 11 to rotate. The rotation of the first drive gear 11 is connected to the circular rotating disk 3 through meshing, allowing the circular rotating disk 3 to rotate inside the vertical support plate 2. This allows the paper cup to rotate to the outside of the offset printing squeegee 24. The offset printing box 4 provides printing adhesive to the offset printing squeegee 24. The longitudinal hydraulic cylinder 23 causes the offset printing squeegee 24 to move towards the outside of the paper cup, allowing the paper cup to be printed.

[0044] By operating the second transverse hydraulic cylinder 18, the clamping force of the inclined support block 10 can be automatically adjusted according to different cup shapes, avoiding the problem of excessive or insufficient pressure caused by traditional spring clamping. This ensures printing stability and prevents cup deformation and damage. By operating the first transverse hydraulic cylinder 15, the cup can be unloaded, greatly reducing the need for manual intervention and improving production efficiency and product consistency.

[0045] Working principle: The inner wall of the paper cup is placed on the outside of the inclined support block 10. The operation of the second horizontal hydraulic cylinder 18 enables the circular moving plate 19 to move. The movement of the circular moving plate 19, through the inclined rotating column 20, enables the circular sliding tube 22 to move on the outside of the circular guide column 21, thereby enabling the multiple inclined support blocks 10 to fix the paper cup.

[0046] The operation of the first drive motor 6 enables the second drive gear 12 to rotate. The rotation of the second drive gear 12, through the meshing connection between the second drive gear 12 and the driven gear 13, enables multiple driven gears 13 to rotate, thereby causing the transverse rotating column 8 to rotate. The rotation of the transverse rotating column 8 enables the paper cup to rotate.

[0047] The operation of the second drive motor 7 enables the first drive gear 11 to rotate. The rotation of the first drive gear 11 is connected to the meshing of the circular rotating disk 3, which allows the circular rotating disk 3 to rotate inside the vertical support plate 2, so that the paper cup can rotate to the outside of the offset printing squeegee 24. The offset printing box 4 can provide printing adhesive to the offset printing squeegee 24. The longitudinal hydraulic cylinder 23 enables the offset printing squeegee 24 to move toward the outside of the paper cup, so that the paper cup can be printed.

[0048] After the paper cup printing is completed, the operation of the first horizontal hydraulic cylinder 15 enables the circular push plate 16 to move. The movement of the circular push plate 16, through the L-shaped push plate 9, enables the paper cup to detach from the outside of the horizontal rotating column 8, so that the paper cup can be fed.

[0049] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
