Description

Technical Field

[0001] This utility model specifically relates to the field of mirror roller cooling technology, and more specifically to a high-precision mirror roller cooling system. Background Technology

[0002] A mirror roller is a roller with a highly polished and flat surface. It has a mirror-like gloss, excellent reflective properties, and extremely low surface roughness with almost no surface defects. During processing, if the temperature of the mirror roller is too high, it will cause the temperature of the material in contact with it to rise. Taking plastic film processing as an example, many plastic materials soften and deform at high temperatures. When the film passes through a high-temperature mirror roller, without cooling measures, the film may experience problems such as stretching deformation and uneven thickness due to excessive temperature. Therefore, mirror rollers need to be cooled during use.

[0003] However, in practice, it has been noted that the commonly used mirror rollers have cooling holes in the center to introduce coolant into the interior. Due to the thickness of the mirror roller, the temperature of the coolant cannot be quickly transferred to the surface of the mirror roller. Therefore, it is necessary to open the cooling holes in advance according to the surface temperature of the mirror roller. Moreover, the cooling holes in the center alone cannot cool the surface of the mirror roller evenly. This uneven cooling can easily lead to local damage to the mirror roller and affect its use. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision mirror roller cooling system. The mirror roller has multiple spirally arranged hollow pipes that can rapidly transfer the temperature of the coolant to the surface of the roller, improving cooling efficiency and effect. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision mirror roller cooling system includes a mirror roller, with roller shafts integrally provided at both ends of the mirror roller. Hollow pipes are arranged in a ring array in the mirror roller, and each hollow pipe has a metal connecting pipe integrally provided at both ends with the mirror roller. The inner side of the metal connecting pipe is connected to the inner side of the hollow pipe, and each hollow pipe is arranged in a spiral shape.

[0007] Both ends of the mirror roller are provided with rotating connecting shells that are fixedly connected to the metal connecting pipe. Each rotating connecting shell is movably connected to a fixed connecting shell at the end away from the mirror roller, and an annular locking sleeve is installed at the connection between the fixed connecting shell and the rotating connecting shell.

[0008] As a further technical solution of this utility model, the rotary connecting shell includes a hollow shell sleeved on the outside of the roller shaft, and a sealing sleeve integrally provided on the inner side of the hollow shell, and the roller shaft passes through the sealing sleeve.

[0009] The hollow shell has first connecting holes in a ring array on its side, corresponding to the metal connecting pipes, and the end of the metal connecting pipe extends through the first connecting holes to the inside of the hollow shell.

[0010] As a further technical solution of this utility model, the fixed connection shell includes a hollow outer shell that fits against the side of the hollow shell, and a sealing sleeve integrally provided in the hollow outer shell to fit with the sealing plug, and the end of the sealing plug is inserted into the inner side of the sealing sleeve.

[0011] As a further technical solution of this utility model, sealing rings are provided between the hollow shell and the hollow outer shell, as well as between the sealing plug and the sealing sleeve, and the inner side of the hollow shell is connected to the inner side of the hollow outer shell.

[0012] As a further technical solution of this utility model, the annular locking sleeve includes two symmetrically arranged L-shaped limiting rings, each of which has an integrally provided flange on its side, and the symmetrical L-shaped limiting rings are connected by bolts to the flanges on the side.

[0013] As a further technical solution of this utility model, the symmetrically described L-shaped limiting rings are respectively sleeved on the outer side of the hollow shell and the outer side of the hollow shell, and the outer side of the hollow shell and the outer side of the hollow shell are respectively integrally provided with corresponding locking edges and limiting rings.

[0014] As a further technical solution of this utility model, each of the L-shaped limiting rings has a limiting groove on its side, and the inner side of the limiting groove is arranged with balls in a ring array, and the balls are respectively located between the locking edge and the L-shaped limiting ring, and between the L-shaped limiting ring and the limiting ring.

[0015] As a further technical solution of this utility model, the side of the locking edge and the side of the limiting ring are respectively provided with an annular groove and an arc-shaped limiting groove corresponding to the limiting groove, and the side of the ball is respectively placed in the annular groove and the arc-shaped limiting groove.

[0016] As a further technical solution of this utility model, the bottom of the hollow shell is integrally provided with a second connecting hole, and a coolant circulation pipe that is threadedly engaged with the second connecting hole is provided below the hollow shell, and the inner side of the coolant circulation pipe is connected to the inner side of the hollow shell.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a spirally arranged hollow pipe within the mirror roller to allow coolant to flow through the inner side of the roller, thereby rapidly cooling the surface of the roller. Furthermore, the annular array of hollow pipes ensures that the coolant flows evenly through the inner side of the roller, thus improving the cooling effect.

[0019] This invention utilizes a rotating connection between a fixed connecting shell and a rotating connecting shell to allow the mirror roller to be cooled while rotating. Combined with a coolant circulation pipe, this ensures the cooling effect of the mirror roller during use. Furthermore, the annular array of metal connecting pipes communicates with the inner side of the hollow shell, allowing the coolant to enter the hollow pipes at different locations evenly, further improving the cooling effect on the mirror roller.

[0020] This invention uses two symmetrically arranged L-shaped limiting rings to fix the fixed connecting shell and the rotating connecting shell. The ball bearings in the L-shaped limiting rings can reduce the friction between the rotating connecting shell and the L-shaped limiting rings when rotating, thereby extending the service life.

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.

[0034] Please see Figure 1-10 This utility model provides a high-precision mirror roller cooling system, including a mirror roller 1, with roller shafts 2 integrally provided at both ends of the mirror roller 1, hollow pipes arranged in a ring array in the mirror roller 1, and metal connecting pipes 3 integrally provided at both ends of each hollow pipe and the inner side of the metal connecting pipe 3 communicating with the inner side of the hollow pipe, and each hollow pipe being arranged in a spiral shape;

[0035] Both ends of the mirror roller 1 are provided with rotating connecting shells 7 that are fixedly connected to the metal connecting pipe 3. Each rotating connecting shell 7 is movably connected to a fixed connecting shell 5 at the end away from the mirror roller 1, and an annular locking sleeve 6 is installed at the connection between the fixed connecting shell 5 and the rotating connecting shell 7.

[0036] In this embodiment, the rotating connecting shell 7 includes a hollow shell 71 sleeved on the outside of the roller shaft 2. The inner side of the hollow shell 71 is integrally provided with a sealing sleeve 72, and the roller shaft 2 passes through the sealing sleeve 72.

[0037] The hollow shell 71 has first connecting holes 73 in a ring array on its side, corresponding to the metal connecting pipe 3, and the end of the metal connecting pipe 3 extends through the first connecting holes 73 to the inside of the hollow shell 71.

[0038] Furthermore, the fixed connection shell 5 includes a hollow outer shell 51 that fits against the side of the hollow shell 71, and the hollow outer shell 51 is integrally provided with a sealing sleeve 54 that fits into the sealing sleeve 72, and the end of the sealing sleeve 72 is inserted into the inner side of the sealing sleeve 54.

[0039] Furthermore, sealing rings are provided between the hollow shell 71 and the hollow outer shell 51, as well as between the sealing sleeve 72 and the sealing tube 54, and the inner side of the hollow shell 71 is connected to the inner side of the hollow outer shell 51.

[0040] Furthermore, the annular locking sleeve 6 includes two symmetrically arranged L-shaped limiting rings 61, each of which has an integrally formed flange 62 on its side, and the symmetrical L-shaped limiting rings 61 are bolted together by the flange 62 on the side.

[0041] Furthermore, the symmetrical L-shaped limiting rings 61 are respectively sleeved on the outer side of the hollow shell 51 and the outer side of the hollow shell 71, and the outer side of the hollow shell 51 and the outer side of the hollow shell 71 are respectively integrally provided with corresponding locking edges 52 and limiting rings 74.

[0042] More specifically, each of the L-shaped limiting rings 61 has a limiting groove 63 on its side, and the inner side of the limiting groove 63 is arranged in a ring array with balls 64, and the balls 64 are respectively located between the locking edge 52 and the L-shaped limiting ring 61 and between the L-shaped limiting ring 61 and the limiting ring 74.

[0043] Furthermore, the side of the locking edge 52 and the side of the limiting ring 74 are respectively provided with an annular groove 53 and an arc-shaped limiting groove 75 corresponding to the limiting groove 63, and the side of the ball 64 is respectively placed in the annular groove 53 and the arc-shaped limiting groove 75.

[0044] Furthermore, the bottom of the hollow shell 51 is integrally provided with a second connecting hole 55, and the lower part of the hollow shell 51 is provided with a coolant circulation pipe 4 that is threadedly engaged with the second connecting hole 55, and the inner side of the coolant circulation pipe 4 is connected to the inner side of the hollow shell 51.

[0045] By adopting the above technical solution, the coolant enters the cavity composed of the hollow outer shell 51 and the hollow shell 71 through the external supply pump and the coolant circulation pipe 4 on either side. Then, it enters the mirror roller 1 evenly through the metal connecting pipe 3 into the spirally arranged hollow pipe, which cools the mirror roller 1. Since there are multiple spirally arranged hollow pipes on the inner side of the mirror roller 1, the cooling effect on the mirror roller 1 is improved. Then, the coolant returns to the storage tank for storing coolant through the rotating connecting shell 7, the fixed connecting shell 5 and the coolant circulation pipe 4 at the other end.

[0046] In this embodiment, the cavity formed between the hollow outer shell 51 and the hollow shell 71 can be used to transport coolant. The coolant enters the cavity formed between the hollow outer shell 51 and the hollow shell 71 through the coolant circulation pipe 4, and finally enters the inner side of the mirror roller 1 through the metal connecting pipe 3.

[0047] More specifically, the end of the roller shaft 2 away from the mirror roller 1 extends through the sealing sleeve 72 and the sealing tube 54 to the end of the hollow shell 51 away from the mirror roller 1, without affecting the normal installation of the roller shaft 2. When the mirror roller 1 is rotated by the roller shaft 2, the mirror roller 1 will drive the hollow shell 71 to rotate through the metal connecting tube 3.

[0048] The working principle of this utility model is as follows: In use, the mirror roller 1 is first installed through the roller shafts 2 at both ends. An external motor can drive the mirror roller 1 to rotate through the roller shafts 2. An external supply pump sends the coolant in the storage tank into the inner side of the hollow shell 51 through the coolant circulation pipe 4. The coolant enters the cavity formed between the hollow shell 51 and the hollow shell 71. Then, the coolant is evenly introduced into the hollow pipes in the mirror roller 1 through the metal connecting pipes 3 arranged in a ring array. The multiple spiral hollow pipes can quickly transfer the temperature of the coolant to the surface of the mirror roller 1, thereby quickly cooling the surface of the mirror roller 1. Moreover, when the mirror roller 1 rotates, the mirror roller 1 will drive the hollow shell 71 to rotate through the metal connecting pipes 3. The limiting ring 74 on the outside of the hollow shell 71 will rotate in the L-shaped limiting ring 61, and the ball 64 will roll between the arc-shaped limiting groove 75 and the limiting groove 63 through friction. Cooling does not affect normal use. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
