Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum roller technology, specifically an aluminum roller that prevents deformation during thermal spraying. Background Technology
[0002] Aluminum rollers have multiple uses in industry and manufacturing. They can be used for rolling, stretching, or pressing metal materials, as printing rollers to transfer ink, in the electronics industry for thin film and circuit board manufacturing, and in the textile industry for fabric flattening and shaping. In short, the uses of aluminum rollers are diverse, depending on their specific design and application. Their main advantages include lightweight, corrosion resistance, high strength, and good thermal conductivity. These advantages make them an indispensable component in many industrial fields. In practical applications, to improve the performance of aluminum rollers in a certain aspect, such as corrosion resistance or wear resistance, it is necessary to spray appropriate coatings on their surface. Since high temperatures are generated during coating, to prevent the aluminum rollers from deforming due to prolonged high temperatures, it is necessary to design an aluminum roller that is resistant to heat-sprayed deformation.
[0003] Meanwhile, a heat-resistant aluminum roller for preventing thermal spraying deformation, with application number CN202122963592.5, includes a roller sleeve. Connecting plates are fixed at both ends of the roller sleeve, and each connecting plate is rotatably connected to a rotating tube via bearings. The opposite ends of the two rotating tubes extend into the roller sleeve. Support frames are fixed to the outer walls of the opposite ends of the two rotating tubes, and the support frames are slidably connected to the roller sleeve. Cover plates are provided at the openings of the opposite ends of the two rotating tubes. Connecting blocks are fixed to the outer walls of the two rotating tubes, and the connecting blocks are rotatably connected to one end of the cover plates via fixed shafts. The roller sleeve also contains two drive assemblies that match the cover plates. Each drive assembly includes a sleeve and a movable rod. One end of the bottom of the sleeve is rotatably connected to the support frame via a rotating component. One end of the movable rod is located inside the sleeve and is slidably connected to the sleeve. The sleeve is filled with a thermal expansion fluid. The other end of the movable rod is rotatably connected to the cover plate via a rotating shaft, and the rotating shaft is positioned near the fixed shaft. This invention can quickly dissipate heat when the internal temperature of the roller exceeds a certain level, preventing deformation and thus improving its service life.
[0004] However, the following problems were found in the implementation of the relevant technologies: Although the existing aluminum rollers can quickly dissipate heat to prevent deformation during spraying, the use of active heat dissipation results in high energy consumption. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides an aluminum roller that prevents thermal spraying deformation. It uses a passive heat dissipation method to dissipate heat, achieving sufficient heat dissipation while consuming less energy, thus having the advantage of low heat dissipation energy consumption.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum roller for preventing deformation during thermal spraying, comprising a roller sleeve, both ends of the inner wall of the roller sleeve being threaded, and both ends of the roller sleeve being threadedly connected to a connecting cylinder, a limiting plate integrally formed at the end of the connecting cylinder away from the roller sleeve, the limiting plate abutting against the corresponding side of the roller sleeve, an opening in the middle of the limiting plate, and a connecting rod fixedly inserted into the inner side of the opening, an air hole communicating with the connecting cylinder in the middle of the connecting rod, and multiple support rods integrally formed in a ring shape on the side of the connecting cylinder away from the limiting plate, the support rods abutting against the corresponding side of the inner wall of the roller sleeve.
[0007] Preferably, the connecting cylinder and the limiting plate, and the connecting cylinder and the support rod are both integrally cast structures.
[0008] Preferably, a support ring is integrally formed between the sides of the plurality of support rods away from the connecting cylinder, and the support ring abuts against the corresponding side of the inner wall of the roller sleeve.
[0009] Preferably, the sidewall of the limiting plate has multiple flange holes arranged in a ring shape.
[0010] Preferably, a rubber plug is inserted into the inner side of the air hole, and a rope loop is attached to the side of the rubber plug away from the limiting plate.
[0011] Preferably, the limiting plate has a circular structure, and the outer wall of the limiting plate and the roller sleeve are flush.
[0012] Preferably, a label is adhered to the middle of one side of the outer wall of the roller sleeve, and a heat insulation film is adhered to the surface of the label.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses multiple support rods to conduct part of the heat from the roller sleeve surface to the surface of the connecting rods through the limiting plate. The air holes opened on the two connecting rods themselves allow ventilation on both sides of the roller sleeve, which can accelerate the dissipation of heat. The passive heat dissipation method consumes less energy.
[0015] 2. This utility model uses multiple support rods to support the inner wall of the roller sleeve to prevent deformation. The support ring and connecting cylinder can improve the strength of the support. The combination of two sets of this structure can prevent the roller sleeve from deforming to a certain extent.
[0016] 3. The multiple internal structures of this utility model are interconnected. When an internal structure is damaged, you only need to rotate the limiting plate to unscrew the connecting cylinder to remove all the internal structures, making the maintenance of the internal structures more convenient.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] like Figures 1 to 4 As shown, this utility model provides an aluminum roller for preventing deformation during thermal spraying, including a roller sleeve 1. Both ends of the inner wall of the roller sleeve 1 are threaded, and both ends of the roller sleeve 1 are threadedly connected to a connecting cylinder 2. The threaded connection facilitates assembly and disassembly. A limiting plate 3 is integrally formed at the end of the connecting cylinder 2 away from the roller sleeve 1, and the limiting plate 3 abuts against the corresponding side of the roller sleeve 1 to ensure the sealing of the roller sleeve 1. An opening 4 is formed in the middle of the limiting plate 3, and a connecting rod 6 is fixedly inserted into the inner side of the opening 4. The joint can be welded to improve performance. The tight connection provides better heat conduction. The middle part of the connecting rod 6 has an air hole 7 that communicates with the connecting cylinder 2. The air holes 7 on both sides allow ventilation on both sides of the roller sleeve 1, which can quickly dissipate internal heat. On the side of the connecting cylinder 2 away from the limiting plate 3, multiple support rods 9 are integrally formed in a ring shape. The support rods 9 abut against the corresponding side of the inner wall of the roller sleeve 1. The multiple support rods 9 can not only support the inner wall of the roller sleeve 1 to prevent it from deforming, but also conduct heat on the surface of the roller sleeve 1, accelerating the heat dissipation of the roller sleeve 1.
[0024] Specifically, the connection between the connecting cylinder 2 and the limiting plate 3, and the connection between the connecting cylinder 2 and the support rod 9 are all integrally cast structures. The integrally cast structure has high structural strength, is durable, and has high thermal conductivity and good heat dissipation.
[0025] Furthermore, a support ring 10 is integrally cast between the sides of the multiple support rods 9 away from the connecting cylinder 2, and the support ring 10 abuts against the corresponding side of the inner wall of the roller sleeve 1. The support ring 10 can improve the structural strength of the multiple support rods 9, prevent the support rods 9 from deforming, and at the same time, it can cooperate with the support rods 9 to support the inner wall of the roller sleeve 1.
[0026] Furthermore, the sidewall of the limiting plate 3 is provided with multiple flange holes 5 arranged in a ring shape to facilitate the connection and fixation of the limiting plate 3 with the external structure.
[0027] It is worth noting that a rubber plug 11 is inserted into the inner side of the air hole 7. When the roller sleeve 1 is to be used after the spraying is completed, the rubber plug 11 can block the air hole 7 to ensure the sealing. During the spraying process, the rubber plug 11 can be pulled out to make the air hole 7 open and ensure the heat dissipation effect. In addition, a rope loop 12 is attached to the side of the rubber plug 11 away from the limiting plate 3. The rope loop 12 can be hooked with a hook structure to make it easy to remove the rubber plug 11.
[0028] It is worth noting that the limiting plate 3 has a circular structure, and the outer wall of the limiting plate 3 and the roller sleeve 1 are flush, which improves the integrity and aesthetics of the aluminum roller and can avoid uneven surface from affecting the spraying process.
[0029] It is worth mentioning that a label paper 8 is adhered to the middle of one side of the outer wall of the roller sleeve 1. The surface of the label paper 8 is used to mark the parameter information of the current roller sleeve 1, such as length and diameter, so as to quickly understand it. In addition, the surface of the label paper 8 is adhered with a heat insulation film to avoid the parameter information from being blurred due to the spraying.
[0030] Working principle: When the roller sleeve 1 is sprayed, the connecting rods 6 on both sides are first fixed by external clamps or other structures. Then, the rope sleeve 12 is hooked by the hook structure to pull out the rubber plug 11. In this way, the air holes 4 on both sides are connected to facilitate ventilation of the roller sleeve 1. Multiple support rods 9 conduct part of the heat on the surface of the roller sleeve 1 to the surface of the connecting rods 6 through the limiting plate 3, which can accelerate the heat dissipation and thus prevent the roller sleeve 1 from deforming due to overheating. At the same time, multiple support rods 9, together with the support ring 10 and the connecting cylinder 2, can support the inner wall of the roller sleeve 1 so that it is not easy to deform.
