Description

Technical Field

[0001] This utility model relates to the field of aluminum foil rolls, and in particular to a wear-resistant wide-width double-zero aluminum foil roll. Background Technology

[0002] Currently, wide-width double-zero aluminum foil rolls are widely used in food packaging, pharmaceutical packaging, and high-end electronic devices as core components of precision rolling equipment. Traditional rolls are mostly forged from high-chromium cast iron or alloy tool steel, and their basic wear resistance is obtained through surface hardening. Their structure usually consists of a roll body, a central shaft, and bearing assemblies, relying on keyways to transmit torque and an external cooling system to control the operating temperature.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Existing aluminum foil rolling equipment, under wide-width processing conditions, suffers from insufficient heat dissipation mechanism, leading to frequent local overheating of the rollers, resulting in increased product dimensional deviations and extended unplanned production line downtime. Utility Model Content

[0004] In order to improve the problem of frequent local overheating of the roll body caused by insufficient heat dissipation mechanism in existing aluminum foil rolling equipment under wide-width processing conditions, which leads to increased product size deviation and extended unplanned downtime of the production line, this application provides a wear-resistant wide-width double-zero aluminum foil roll.

[0005] This application provides a wear-resistant wide-width double-zero aluminum foil roll with the following technical solution: A wear-resistant wide-width double-zero aluminum foil roll includes a heat dissipation assembly and a limiting assembly. The limiting assembly is installed on the heat dissipation assembly. The heat dissipation assembly includes a roll body, and a connecting shaft is fixed to the side surface of the roll body. A fixing plate is fixed to the surface of the roll body. A connecting roll is fixed to the surface of the fixing plate. A heat dissipation pipe is provided on the inner surface of the fixing plate. An annular block is fixed to the side surface of the heat dissipation pipe. A connecting sleeve is fitted on the surface of the heat dissipation pipe. A first connecting block is fixed to the surface of the annular block. A threaded column is fixed to the surface of the first connecting block. A rubber sleeve is fitted on the surface of the threaded column. A second connecting block is fixed to the surface of the connecting sleeve. A limiting bolt is threadedly connected to the surface of the threaded column. A limiting block is fixed to the surface of the connecting roll. A second limiting bolt is threadedly connected to the surface of the threaded column.

[0006] By adopting the above technical solution, the frictional heat generated during the rolling process is quickly conducted to the liquid working fluid in the heat dissipation tube through the connecting roller. Dynamic temperature control is achieved by utilizing the latent heat absorption principle of phase change, thereby extending the surface smoothness of the aluminum foil. The interference fit structure between the heat dissipation tube and the connecting roller and the annular block positioning mechanism constitute the core heat transfer path, ensuring uniform release of thermal stress and avoiding local overheating and deformation.

[0007] In a further configuration, the limiting component includes a roller sleeve fitted on the surface of the connecting roller, and a groove formed on the inner wall of the roller sleeve. The limiting component also includes a protective cover on the surface of the connecting roller, and a slot formed on the surface of the protective cover. The surface of the protective cover is provided with a limiting element.

[0008] By adopting the above technical solution, a double-layer mechanical protection system is formed - the roller sleeve bears the main load, while the protective cover is specially designed to resist the impact of flying metal chips. The locking mechanism composed of limit bolts and limit parts allows the protective cover to be opened and closed by one hand, reducing the time spent on daily maintenance to a minimum.

[0009] Further configuration: the surface of the slot contacts the inner wall of the limiting block, and the inner wall of the groove contacts the surface of the limiting block.

[0010] By adopting the above technical solution, the limiting block is used as an intermediate conversion component to convert the horizontal thrust of the slot into vertical pressure acting on the groove, which facilitates the protective cover to limit the roller sleeve, and at the same time facilitates the limiting block to drive the roller sleeve to rotate.

[0011] Furthermore, the heat dissipation pipe is filled with heat dissipation liquid, and multiple sets of heat dissipation pipes are provided, which are arranged symmetrically to each other.

[0012] By adopting the above technical solution, the axially distributed heat dissipation pipes 105 form a ring-shaped cooling matrix, which improves the heat dissipation effect and has a significant improvement effect compared with the single pipe layout.

[0013] Furthermore, the surface of the heat dissipation pipe is in contact with the inner wall of the connecting roller, and the connecting roller and the fixing plate are an integrated structure.

[0014] By adopting the above technical solution, the interface between the interference fit heat dissipation tube 105 and the connecting roller 104 eliminates contact thermal resistance.

[0015] Further configuration: the inner wall of the rubber sleeve contacts the inner wall of the threaded post, and the surface of the first limiting bolt contacts the surface of the second connecting block.

[0016] By adopting the above technical solution, the rubber sleeve can make the connecting sleeve fit more closely to the heat dissipation pipe, thus improving the sealing effect.

[0017] Compared with related technologies, the wear-resistant wide-width double-zero aluminum foil roll provided by this utility model has the following beneficial effects:

[0018] This utility model provides a wear-resistant wide-width double-zero aluminum foil roll. By integrating a fixing plate and a heat dissipation pipe with built-in heat dissipation liquid on the surface of the roll body, the heat dissipation pipe directly contacts the connecting roll for heat exchange, achieving rapid cooling and thus improving the stability of continuous operation of the equipment. The design of the combination of a limit bolt and a sliding connecting sleeve allows the axial displacement and separation of the heat dissipation pipe to be completed by hand. The heat dissipation pipe can be separated for cleaning or liquid replenishment without tools, reducing maintenance costs.

[0019] This utility model provides a wear-resistant wide-width double-zero aluminum foil roll. A protective cover is used to cover the outside of the roll sleeve and form a physical barrier through contact with the side wall surface, which effectively protects the side surface of the heat dissipation pipe. The synergistic effect of the limiting bolt and the limiting component means that the locking state of the protective cover can be released by simply loosening the bolt, so that the roll sleeve can be exposed to the outside for grinding maintenance or overall replacement, which significantly improves maintenance efficiency.

[0025] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0026] Example 1:

[0027] like Figure 1-4As shown, this utility model discloses a wear-resistant wide-width double-zero aluminum foil roll, comprising a heat dissipation assembly 1 and a limiting assembly 2. The limiting assembly 2 is mounted on the heat dissipation assembly 1. The heat dissipation assembly 1 includes a roll body 101, and a connecting shaft 102 is fixed to the side surface of the roll body 101. A fixing plate 103 is fixed to the surface of the roll body 101, and a connecting roll 104 is fixed to the surface of the fixing plate 103. A heat dissipation pipe 105 is provided on the inner surface of the fixing plate 103, and an annular block 106 is fixed to the side surface of the heat dissipation pipe 105. A connecting sleeve 107 is fitted on the surface of the heat pipe 105. A connecting block 108 is fixed on the surface of the annular block 106. A threaded post 109 is fixed on the surface of the connecting block 108, and a rubber sleeve 110 is fitted on the surface of the threaded post 109. A connecting block 113 is fixed on the surface of the connecting sleeve 107. A limiting bolt 114 is connected to the surface of the threaded post 109 by thread. A limiting block 111 is fixed on the surface of the connecting roller 104. A limiting bolt 112 is connected to the surface of the threaded post 109 by thread.

[0028] like Figure 1-4 As shown, the roller body 101 has a fixed plate 103 and a heat dissipation pipe 105 with built-in heat dissipation liquid on its surface. When the roller body 101 rotates around the axis, it drives the heat dissipation pipe 105 to rotate synchronously. The heat dissipation liquid inside the pipe rotates with the pipe body to form a dynamic heat exchange circuit. It continuously absorbs the heat generated by the connecting roller 104 through heat convection. At the same time, the operator can slide the connecting sleeve 107 along the guide groove axially and loosen the limit bolt 114 counterclockwise to realize the quick removal and replacement of the heat dissipation pipe 105. The side wall of the heat dissipation pipe 105 is radially limited by the arc-shaped groove of the protective cover 203. When the protective cover 203 slides along the roller sleeve 201 axially, its inner edge always maintains a clearance fit with the outer wall of the heat dissipation pipe 105. When the limit bolt 112 is tightened clockwise to release the lock, the protective cover 203 can be moved out of the roller sleeve 201, so that the roller sleeve 201 is exposed to the working range of the external grinding device.

[0029] like Figure 1-4 As shown, the heat pipe 105 is filled with heat dissipation liquid, and multiple sets of heat pipe 105 are provided, and the heat pipe 105 are arranged symmetrically to each other.

[0030] like Figure 1-4 As shown, the surface of the heat dissipation pipe 105 is in contact with the inner wall of the connecting roller 104, and the connecting roller 104 and the fixing plate 103 are an integrated structure.

[0031] like Figure 1-4 As shown, the inner wall of the rubber sleeve 110 is in contact with the inner wall of the threaded post 109, and the surface of the limiting bolt 114 is in contact with the surface of the connecting block 113.

[0032] In practice, the surface of the roller body 101 is provided with a fixing plate 103 and a heat dissipation pipe 105, and the inside of the heat dissipation pipe 105 is filled with heat dissipation liquid, which can dissipate heat from the connecting roller 104 when the roller body 101 is working, thereby improving work efficiency. By turning the limit bolt 114 and simultaneously sliding the connecting sleeve 107, the connecting sleeve 107 can be easily separated from the heat dissipation pipe 105, making it easy to disassemble the heat dissipation pipe 105 and replace the heat dissipation liquid inside the heat dissipation pipe 105.

[0033] Example 2:

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the limiting component 2 includes a roller sleeve 201 sleeved on the surface of the connecting roller 104, and a groove 202 is provided on the inner wall of the roller sleeve 201. The limiting component 2 also includes a protective cover 203 on the surface of the connecting roller 104, and a slot 204 is provided on the surface of the protective cover 203. A limiting member 205 is provided on the surface of the protective cover 203.

[0035] like Figure 1-4 As shown, the surface of the slot 204 is in contact with the inner wall of the limiting block 111, and the inner wall of the groove 202 is in contact with the surface of the limiting block 111.

[0036] In practice, the protective cover 203 can be limited by contacting the side surface of the roller sleeve 201. The protective cover 203 can protect the side surface of the heat dissipation pipe 105. By turning the limiting bolt 112 and simultaneously removing the limiting part 205, the protective cover 203 can be removed, making it convenient to remove the roller sleeve 201 for grinding or replacement.

[0037] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0038] 1. The quick-release structure of heat pipe 105 and connecting sleeve 107 enables non-destructive disassembly and assembly through thread drive, and the integrated liquid cooling channel enhances heat dissipation efficiency, ensuring stable operation of the equipment for a long time;

[0039] 2. The combined protective system of protective cover 203 and limit component 205 has both impact protection and quick unlocking function. It adopts a mechanical interlocking mechanism controlled by limit bolt 212, which greatly improves the maintenance efficiency of roller sleeve 201.

[0040] In this technical solution, the surface of the roller body 101 is provided with a fixing plate 103 and a heat dissipation pipe 105, and the heat dissipation pipe 105 is filled with heat dissipation liquid, which can dissipate heat from the connecting roller 104 when the roller body 101 is working, thereby improving working efficiency. By turning the limit bolt 114 and simultaneously sliding the connecting sleeve 107, the connecting sleeve 107 can be easily separated from the heat dissipation pipe 105, making it easy to disassemble the heat dissipation pipe 105 and replace the heat dissipation liquid inside the heat dissipation pipe 105.

[0041] The protective cover 203 can be limited by contacting the side surface of the roller sleeve 201. The protective cover 203 can protect the side surface of the heat dissipation pipe 105. The protective cover 203 can be disassembled by turning the limiting bolt 112 and simultaneously removing the limiting part 205, which makes it easy to disassemble the roller sleeve 201 for grinding or replacement.
