Description

Technical Field

[0001] The utility model relates to the technical field of paper guide rollers, in particular to a guide roller provided with an exhaust structure. Background Art

[0002] Currently, commonly used wrapping paper is generally a multi-layer structure of PE / paper / PE / AL / EMAA / PE. During the production and processing of wrapping paper, the paper guide roller is used to stabilize the movement of the paper web and control the direction of the paper web. When guiding the paper, a part of the paper is covered on the paper guide roller. When the paper covered on the paper guide roller moves quickly, airflow will be generated between the paper and the paper guide roller. The airflow will cause a gap between the paper and the paper guide roller, thereby forming bubbles, causing the aluminum foil of the wrapping paper to wrinkle and rupture. At the same time, the existing paper guide rollers are mostly made of aluminum materials, and the wear resistance is not high enough. Based on the above problems, a guide roller with an exhaust structure is proposed. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a guide roller with an exhaust structure.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a guide roller with an exhaust structure, comprising a roller body, both ends of the roller body are connected to a rotating shaft, a plurality of groups of exhaust grooves are provided on the surface of the roller body, and the plurality of groups of exhaust grooves are arranged equidistantly, the roller body comprises an aluminum cylinder and a carbon fiber sleeve, the carbon fiber sleeve is sleeved on the outer surface of the aluminum cylinder, and both ends of the roller body are sleeved with limiting fixing sleeves for fixing the carbon fiber sleeve.

[0005] As a further description of the above technical solution:

[0006] The exhaust groove has a groove depth of 0-5 mm and a groove width of 0-3 mm.

[0007] As a further description of the above technical solution:

[0008] The interior of the aluminum cylinder is hollow, and a plurality of disc-shaped supporting frames are fixed inside the aluminum cylinder.

[0009] As a further description of the above technical solution:

[0010] Both ends of the aluminum cylinder are provided with a plurality of internal thread grooves, and the surface of the limiting fixing sleeve is provided with a plurality of counterweight holes. The plurality of internal thread grooves and the plurality of counterweight holes are arranged in a circular array, and the internal thread grooves correspond to the counterweight holes one by one.

[0011] As a further description of the above technical solution:

[0012] A counterweight block for adjusting dynamic balance is installed inside the internal thread groove and the counterweight hole.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, an exhaust groove is arranged on the surface of the roller body, so that the bubbles generated by the airflow between the paper covering the paper guide roller and the paper guide roller when the paper covers the paper guide roller moves rapidly are discharged from the exhaust groove, thereby avoiding the aluminum foil of the packaging paper from being wrinkled or broken, and improving the production quality.

[0015] 2. In the utility model, the double-layer structure of the aluminum cylinder and the carbon fiber cylinder sleeve is more wear-resistant and lighter than a single-layer aluminum roller body, and has a lower cost than the entire carbon fiber roller body. At the same time, the limiting fixing sleeve is used to facilitate the assembly and fixation of the entire roller body, and the limiting fixing sleeve can also limit the paper and prevent it from shifting.

[0016] 2. In the utility model, through the arrangement of the internal thread groove, the counterweight hole and the counterweight block, a bolt is arranged at one end of the counterweight block, which can pass through the counterweight hole and cooperate with the internal thread groove, thereby playing the role of fixing the limit sleeve. At the same time, the dynamic balance adjustment of the roller body can be achieved by only adjusting the different specifications of the counterweight block, thus killing two birds with one stone.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3The utility model provides an embodiment: a guide roller with an exhaust structure, including a roller body 1, both ends of the roller body 1 are connected to a rotating shaft 4, a plurality of exhaust grooves 2 are provided on the surface of the roller body 1, the plurality of exhaust grooves 2 are arranged at equal intervals, the exhaust grooves 2 have a groove depth of 0-5mm, and a groove width of 0-3mm. By arranging the exhaust grooves 2 on the surface of the roller body 1, bubbles generated by airflow between the paper covered on the paper guide roller and the paper guide roller when the paper is moving rapidly are discharged from the exhaust grooves 2, thereby avoiding the wrinkling and rupture of the aluminum foil of the packaging paper and improving the production quality.

[0024] The roller body 1 includes an aluminum cylinder 11 and a carbon fiber sleeve 12. The carbon fiber sleeve 12 is sleeved on the outer surface of the aluminum cylinder 11. Both ends of the roller body 1 are sleeved with limiting fixing sleeves 3 for fixing the carbon fiber sleeve 12 to form a double-layer structure. Compared with a single-layer aluminum roller body, it is more wear-resistant and lighter in texture. Compared with the entire carbon fiber roller body, it has a lower cost. At the same time, with the limiting fixing sleeve 3, the assembly and fixation of the entire roller body 1 are convenient, and the limiting fixing sleeve 3 can also limit the paper and prevent the paper from shifting. The interior of the aluminum cylinder 11 is hollow, and a plurality of disc-shaped support frames 14 are fixed inside the aluminum cylinder 11, which further increases the strength of the hollow aluminum cylinder 11.

[0025] Both ends of the aluminum cylinder 11 are provided with multiple internal thread grooves 13, and the surface of the limiting fixing sleeve 3 is provided with multiple counterweight holes 5. The multiple internal thread grooves 13 and the multiple counterweight holes 5 are arranged in a circular array, and the internal thread grooves 13 correspond to the counterweight holes 5 one by one. The internal thread grooves 13 and the counterweight holes 5 are jointly installed with counterweight blocks for adjusting dynamic balance. One end of the counterweight block is provided with a bolt, which can pass through the counterweight hole 5 and cooperate with the internal thread groove 13, so as to play the role of fixing the limiting sleeve 3. At the same time, only the different specifications of the counterweight blocks need to be adjusted to achieve the dynamic balance adjustment of the roller body 1, thus killing two birds with one stone.
