Description

Technical Field

[0001] The utility model relates to the technical field of coating rubber rollers, in particular to a rubber roller for tipping paper coating. Background Technique

[0002] Tipping paper, also known as tipping paper, is a cigarette packaging material, specifically used for cigarette filter tip wrapping. Tipping paper is usually a decorative paper obtained by printing and processing the base paper. Its pattern is based on the cross-section of tobacco leaves, and the color is antique, matte (or slightly matte), giving people a simple and elegant feeling. When tipping paper is produced and processed, it usually needs to be coated with a layer of glue on its surface, so a coating rubber roller is required. Currently, the rubber roller is generally a roller-shaped product with a core made of metal or other materials and an outer covering of rubber vulcanized. After the rubber roller is used for a long time, the outer rubber layer on the rubber roller will gradually age, so it is necessary to periodically replace the rubber roller. However, replacing the entire rubber roller will result in a high cost. Therefore, we propose a rubber roller for tipping paper coating to solve the above problems. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a rubber roller for tipping paper coating proposed by an embodiment of the present utility model includes a hollow roller body 1. End caps 2 are fixed at both ends of the hollow roller body 1. Connecting shafts 3 are fixed on the surfaces of the two end caps 2. An outer rubber sleeve 4 is sleeved on the surface of the hollow roller body 1. Two guiding strip blocks 5 are symmetrically fixed on the inner wall of the outer rubber sleeve 4. Two guiding grooves 6 adapted to the guiding strip blocks 5 are symmetrically formed on the surface of the hollow roller body 1. A rotating block 7 is threadedly connected to the surface of one of the connecting shafts 3. Four L-shaped blocks 8 are fixedly arranged in a circumferential array on one side wall of the rotating block 7. A circular block 9 is slidably sleeved on the surface of one of the connecting shafts 3. A groove 10 adapted to the L-shaped blocks 8 is formed on the surface of the circular block 9. One ends of the four L-shaped blocks 8 are all embedded and installed in the groove 10. Two cross bars 11 are symmetrically fixed on one side wall of the circular block 9. Both of the two cross bars 11 slidably penetrate through the side wall of the adjacent end cap 2. One ends of the two cross bars 11 are rotatably connected to a connecting rod 12 through a pin shaft. One ends of the connecting rods 12 are rotatably connected to a connecting block 13 through a pin shaft. Two T-shaped guiding rods 14 are symmetrically fixed on the inner wall of the hollow roller body 1. The connecting blocks 13 are slidably connected to the surfaces of the corresponding T-shaped guiding rods 14. Blocks 15 are fixed on the surfaces of the connecting blocks 13. Slots 16 adapted to the blocks 15 are formed on the surfaces of the two guiding strip blocks 5. The blocks 15 slidably penetrate through the adjacent side walls of the hollow roller body 1 and are clamped in the corresponding slots 16. When the outer rubber sleeve 4 ages or is damaged and needs to be replaced, the disassembly process is as follows: rotate the rotating block 7, and the rotating block 7 will rotate outwards. The rotating block 7 can drive the circular block 9 to move outwards through the L-shaped blocks 8. The circular block 9 can drive the two cross bars 11 to move outwards. The cross bars 11 can drive the corresponding connecting rods 12 to move. The connecting rods 12 can drive the corresponding connecting blocks 13 to move towards the axis of the hollow roller body 1. The connecting blocks 13 can drive the corresponding blocks 15 to disengage from the corresponding slots 16. In this way, the guiding strip blocks 5 together with the outer rubber sleeve 4 can be disassembled from the hollow roller body 1. The operation is relatively simple. The process of installing the outer rubber sleeve 4 onto the hollow roller body 1 will not be elaborated here. Therefore, when the outer rubber sleeve 4 ages or is damaged, it can be replaced relatively conveniently without replacing the whole rubber roller, thereby reducing costs.

[0024] As Figure 1 and Figure 3As shown, in some embodiments, anti-slip grooves are provided on the surface of the rotating block 7, which can play a good anti-slip role, thus facilitating the user to rotate. External threads are provided on the surface of one of the connecting shafts 3, internal threads adapted to the external threads are provided in the middle of the rotating block 7, and a through hole adapted to the connecting shaft 3 is provided in the middle of the round block 9, so that the round block 9 can move smoothly on the connecting shaft 3. Two sliding holes adapted to the cross bar 11 are symmetrically provided on the side wall of one of the end caps 2, so that the two cross bars 11 can pass through the adjacent end caps 2 smoothly. A guiding hole adapted to the T-shaped guiding rod 14 is provided at one end of the connecting block 13, so that the connecting block 13 can slide smoothly on the T-shaped guiding rod 14. Perforations adapted to the clamping blocks 15 are provided on both side walls of the hollow roller body 1, so that the clamping blocks 15 can pass through the adjacent side walls of the hollow roller body 1 smoothly, and thus the clamping blocks 15 can be inserted into the card slots 16 on the corresponding guiding strip blocks 5 smoothly.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
