Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, in particular to a squeezing mechanism and a squeezing roller. Background Art

[0002] In recent years, with the advancement of foil production technology, the produced foil (i.e. copper foil) has gradually become lighter and thinner.

[0003] During the foil production process, after passing through an antioxidant solution, the foil typically undergoes a squeeze-out process. Currently, a squeeze-out mechanism is typically used to squeeze out the antioxidant solution from both sides of the foil. Existing squeeze-out mechanisms generally include two side plates positioned front-to-back, a squeeze-out assembly, and an upper and lower drive assembly. The squeeze-out assembly includes a squeeze-out roller and a steel roller, each staggered in an upper and lower arrangement. The squeeze-out roller includes a squeeze-out roller body and an adhesive layer covering the outside of the squeeze-out roller body. The ends of the squeeze-out roller body are slidably mounted on the inner sides of the two side plates. The upper and lower drive assemblies are used to drive the squeeze-out roller body up and down relative to the two side plates, thereby driving the adhesive layer to move synchronously. The ends of the steel roller are rotatably mounted on the inner sides of the two side plates. In actual use, the foil passes over the steel roller, and the upper and lower drive assemblies drive the squeeze-out roller body and the adhesive layer downward, thereby providing a compressive force to the squeeze-out roller, thereby squeezing the foil through the adhesive layer and squeezing out the antioxidant solution from both sides of the foil.

[0004] With the development of thinner and faster foil materials, in the process of squeezing foil materials using the squeezing rollers of the existing squeezing mechanism, due to the increase in the speed of the produced foil materials, it is necessary to provide a larger pressing force for the squeezing rollers through the upper and lower drive components, so that the antioxidant liquid on both sides of the foil can be squeezed out through the adhesive layer of the squeezing rollers. However, the adhesive layer is prone to deformation under the continuous large pressing force, so that the antioxidant liquid on both sides of the foil cannot be fully and effectively squeezed out, thereby reducing production efficiency.

[0033] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0034] Please refer to Figures 1 to 5 An embodiment of the present invention provides a squeezing mechanism, which includes two side plates 10 arranged in a front-to-rear direction, a squeezing assembly 20 , an upper and lower driving assembly 30 , and a rotating driving assembly 40 .

[0035] like Figures 1 to 4 As shown, the squeezing assembly 20 includes a squeezing roller 21 and a steel roller 22. The squeezing roller 21 and the steel roller 22 are staggered in an up-down manner, that is, the axis of the squeezing roller 21 and the axis of the steel roller 22 are not in the same vertical plane. In this embodiment, the squeezing roller 21 is located above and to the left of the steel roller 22.

[0036] like Figure 4 and Figure 5 As shown, the squeezing roller 21 is used to squeeze the foil (i.e., copper foil) to squeeze out the antioxidant liquid on both sides of the foil. Specifically, the squeezing roller 21 includes a squeezing roller body 211, a first adhesive layer 212, and a second adhesive layer 213.

[0037] The ends of the squeeze roller body 211 are slidably mounted on the inner sides of the two side panels 10. A first adhesive layer 212 covers the exterior of the squeeze roller body 211. A second adhesive layer 213 covers the exterior of the first adhesive layer 212. The Shore hardness of the first adhesive layer 212 is lower than that of the second adhesive layer 213. The Shore hardness of the first adhesive layer 212 is 60-65, preferably 65, while the Shore hardness of the second adhesive layer 213 is 75-80, preferably 80. The squeeze roller body 211 provides mounting support for the first and second adhesive layers 212, 213. The second adhesive layer 213 can squeeze the foil to drain the antioxidant liquid from both sides of the foil. The Shore hardness of the first adhesive layer 212 is lower than that of the second adhesive layer 213, which relieves the stress on the second adhesive layer 213, thereby providing a buffer for the second adhesive layer 213. The vertical drive assembly 30 is used to drive the squeeze roller body 211 to move up and down relative to the two side panels 10. The vertical movement of the squeeze roller body 211 drives the first and second adhesive layers 212, 213 to move synchronously. The vertical drive assembly 30 drives the squeeze roller body 211, the first and second adhesive layers 212, 213 downward, thereby providing a compressive force to the squeeze roller 21. This allows the second adhesive layer 213 to squeeze the foil. The Shore hardness of the first adhesive layer 212 provides a good cushioning effect on the second adhesive layer 213, while the Shore hardness of the second adhesive layer 213 provides a good squeezing effect on the foil.

[0038] The squeeze roller body 211 is made of 45# steel. Both the first and second rubber layers 212 and 213 are black EPDM rubber layers. The first rubber layer 212 is 15-20 mm thick, preferably 15 mm, while the second rubber layer 213 is 10-15 mm thick, preferably 10 mm. EPDM rubber has excellent elasticity and is not easily deformed. This thickness of the first rubber layer 212 provides a good cushioning effect for the second rubber layer 213, while the thickness of the second rubber layer 213 provides a good extrusion effect on the foil.

[0039] In an alternative solution, the first adhesive layer 212 and the second adhesive layer 213 may both be nitrile rubber layers, which have advantages such as good elasticity and heat resistance and are not easily deformed.

[0040] In another alternative solution, the first adhesive layer 212 and the second adhesive layer 213 may both be silicone layers, which have good strength and are not easily deformed.

[0041] In this embodiment, Figure 1 and Figure 5As shown, two support plates 13 are disposed on the inner sides of the two side plates 10, arranged in a front-to-back relationship. The ends of the squeeze roller body 211 are rotatably mounted on the inner sides of two connecting plates 15, which are disposed in a front-to-back relationship, via two bearing blocks 2111. The two connecting plates 15 are mounted on the inner sides of two connecting blocks 14, which are disposed in a front-to-back relationship and slideably mounted on the inner sides of the two support plates 14.

[0042] The two connecting blocks 14 are respectively slidably arranged on the inner sides of the two support plates 13. Specifically, two first slide rails 131 are respectively provided on the inner sides of the two support plates 13. The length direction of the first slide rails 131 is the same as the height direction of the support plates 13 and the side plates 10. Two first sliders 132 are respectively provided on the outer sides of the two connecting blocks 14. The two first sliders 132 are respectively slidably matched with the two first slide rails 131.

[0043] like Figures 1 to 5 As shown, the up and down driving assembly 30 includes two cylinders 31, which are respectively arranged at the bottom ends of the two support plates 13 through two cylinder plates 311 and are respectively located below the two connecting blocks 14. The two connecting plates 15 are located between the two cylinders 31. The ends of the output shafts of the two cylinders 31 respectively pass through the through holes of the two cylinder plates 311 and are respectively connected to the bottom ends of the two connecting blocks 14. The two cylinders 31 are respectively used to drive the two connecting blocks 14 to move up and down, thereby driving the two connecting plates 15 to move up and down, and further driving the squeezing roller body 211 to move up and down.

[0044] In this embodiment, the ends of the output shafts of the two cylinders 31 are connected to the bottom ends of the two connecting blocks 14 through a cylinder block 312. The two cylinders 31 are respectively used to drive the corresponding cylinder block 312 to move up and down, thereby respectively driving the two connecting blocks 14 to move up and down.

[0045] Two guide rods 17 are provided at the tops of the two connecting blocks 14, and two guide plates 16 are provided at the tops of the two support plates 13, arranged in a front-to-rear orientation. The guide plates 16 are positioned above the two connecting blocks 14 and each has two guide holes. The tops of the two guide rods 17 pass through the guide holes of the two guide plates 16 and are positioned above them. A limiting sleeve 18 is sleeved around the tops of the guide rods 17. The limiting sleeves 18 of the two guide rods 17 are positioned above the two guide plates 16, and the outer diameter of the limiting sleeve 18 is larger than the inner diameter of the guide holes of the guide plates 16. The vertical movement of the two connecting blocks 14 drives the two guide rods 17 to move up and down relative to the two guide plates 16, thereby driving the two limiting sleeves 18 to move up and down. The guide rods 17 guide the vertical movement of the corresponding connecting blocks 14, while the limiting sleeve 18 limits the downward movement of the corresponding connecting blocks 14.

[0046] In this embodiment, two mounting blocks 171 are respectively provided at the top of the two connecting blocks 14. The tops of the two mounting blocks 171 are respectively provided with two mounting holes, and the bottom ends of the two guide rods 17 are respectively disposed in the two mounting holes. The provided mounting blocks 171 facilitate the installation of the guide rods 17.

[0047] The steel roller 22 is used to support the foil. Its two ends are rotatably mounted on the inner sides of the two side panels 10. In this embodiment, mounting holes 11 are provided on the inner sides of the side panels 10. The two ends of the steel roller 22 are rotatably mounted in these mounting holes 11 of the two side panels 10 via bearings or the like. One end of the steel roller 22 extends out of the corresponding mounting hole 11 of the side panel 10. For example, the rear end of the steel roller 22 extends out of the mounting hole 11 of the rear side panel 10 and is connected to the rotation drive assembly 40. The steel roller 22 is made of the same material as the squeeze roller body 21. The rotation drive assembly 40 is used to drive the steel roller 22 in rotation.

[0048] In this embodiment, two squeeze assemblies 20 are arranged spaced apart from each other. The number of vertical drive assemblies 30 and rotation drive assemblies 40 corresponds to the number of squeeze assemblies 20, also two each. The presence of two squeeze assemblies 20 improves the foil squeezing effect and further increases production efficiency.

[0049] In this embodiment, the structures of the two rotation drive components 40 are different. Specifically, Figure 1 and Figure 2As shown, among the two rotation drive assemblies 40, the rotation drive assembly 40 connected to one end of the steel roller 22 of the squeezing assembly 20 located on the left includes a first motor 42 and a reducer 41. The reducer 41 is arranged on the outside of one of the side plates 10, such as the outside of the rear side plate 10, through the reducer plate 411. The first motor 42 is arranged on the reducer 41. The end of the output shaft of the first motor 42 is connected to the end of the input shaft of the reducer 41. The end of the output shaft of the reducer 41 is connected to one end of the corresponding steel roller 22. The first motor 42 is used to drive the corresponding steel roller 22 to rotate through the reducer 41. The rotating drive assembly 40 connected to one end of the steel roller 22 of the squeezing assembly 20 located on the right includes a second motor 43 and a synchronous belt module, wherein the outer side of one side plate 10, for example, the outer side of the side plate 10 located at the rear is connected to the motor plate 431 through a pillar 432, and the number of pillars 432 can be set according to actual conditions. The second motor 43 is arranged on one side of the motor plate 431, and the end of the output shaft of the second motor 43 passes through the through hole of the motor plate 431 and is located between the motor plate 431 and the side plate 10 located at the rear. The synchronous belt module includes a driving wheel 441, a driven wheel 442 and a synchronous belt sleeved on the outer periphery of the driving wheel 441 and the driven wheel 442. The driving wheel 441 and the driven wheel 442 are both located between the motor plate 431 and the side plate 10 located at the rear. The driving wheel 441 is sleeved on the outer periphery of the end of the output shaft of the second motor 43, and the driven wheel 442 is sleeved on the outer periphery of one end of the corresponding steel roller 22. The second motor 43 is used to drive the driving wheel 441 to rotate, thereby driving the corresponding steel roller 22 to rotate through the driven wheel 442 and the synchronous belt.

[0050] In other embodiments, the structures of the two rotation drive assemblies 40 may also be the same.

[0051] Furthermore, if Figures 1 to 4 、 Figure 6 As shown, the present invention further includes a pressure roller 50 and a pressure roller driving assembly 60 .

[0052] Of the two squeezing assemblies 20, the one on the left has a pressure roller 50 installed on one side of its steel roller 22, for example, on the left side. The pressure roller 50 is used to squeeze the foil to initially squeeze out the antioxidant liquid on both sides of the foil. The two ends of the pressure roller 50 are rotatably mounted on the inner sides of two pressure roller mounting plates 52 via two pressure roller bearing seats 51. The two pressure roller mounting plates 52 are arranged in a front-to-back relationship. One end of each side plate 10, for example, the left end, is provided with two L-shaped plates 19 arranged in a front-to-back relationship. The two pressure roller mounting plates 52 are slidably mounted on the adjacent sides of the two L-shaped plates 19. Specifically, two second slide rails 521 are provided on the adjacent sides of the two L-shaped plates 19. The second slide rails 521 extend in the left-right direction. Two second sliders 522 are provided on the outer sides of the two pressure roller mounting plates 52. The two second sliders 522 slide in a sliding engagement with the two second slide rails 521.

[0053] The pressure roller drive assembly 60 is used to drive the two pressure roller mounting plates 52 to move toward or away from the steel roller 22, thereby driving the pressure roller 50 to move toward or away from the steel roller 22. The pressure roller drive assembly 60 drives the pressure roller 50 to move toward the steel roller 22, thereby providing a pressing force for the pressure roller 50, so that the foil can be extruded by the pressure roller 50.

[0054] The pressure roller 50 and the steel roller 22 are staggered, meaning the axes of the pressure roller 50 and the steel roller 22 are not in the same horizontal plane. In this embodiment, the axis of the pressure roller 50 is located above the axis of the steel roller 22. This arrangement allows the antioxidant liquid on the foil to flow only downward between the pressure roller 50 and the steel roller 22 during the extrusion of the foil by the pressure roller 50, thereby improving the stability of the foil extrusion by the pressure roller 50.

[0055] The roller drive assembly 60 includes two roller cylinders 61, each located between the two L-shaped plates 19 and connected to each L-shaped plate 19. Specifically, the roller cylinders 61 are mounted on either side of two cylinder bases 611, with one end of each base connected to the end of the L-shaped plate 19 facing away from the corresponding side plate 10. The ends of the output shafts of the roller cylinders 61 are connected to the outer sides of the roller mounting plates 52. The roller cylinders 61 are used to drive the roller mounting plates 52 toward or away from the steel roller 22.

[0056] In this embodiment, the end of the output shaft of the pressure roller cylinder 61 is connected to a connecting piece 612, and the connecting pieces 612 of the two pressure roller cylinders are respectively arranged on the outside of the two pressure roller mounting plates 52. The two pressure roller cylinders 61 respectively drive the two pressure roller mounting plates 52 to move toward or away from the steel roller 22 through their respective connecting pieces 612.

[0057] The top of the pressure roller mounting plate 52 is provided with a avoidance position 523 for avoiding the squeezing roller 21 of the squeezing assembly 20 located on the left. Figure 4 and Figure 6 shown.

[0058] In actual application of the present invention, after the foil passes between the pressure roller 50 and the steel roller 22 of the squeezing assembly on the left, bypasses over the steel roller 22 of the squeezing assembly 20 on the left, and bypasses over the steel roller 22 of the squeezing assembly 20 on the right, the two rotating drive assemblies 40 are first used to respectively drive the steel rollers 22 of the two squeezing assemblies 20 to rotate, and the foil can be supported by the steel rollers 22 of the two squeezing assemblies 20 respectively. Then, the two pressing roller cylinders 61 drive the pressing roller 50 to move toward the direction close to the steel roller 22 to provide a pressing force for the pressing roller 50. In this way, the pressing roller 50 can squeeze the foil, thereby achieving the preliminary squeezing out of the antioxidant liquid on both sides of the foil. At the same time, the two upper and lower driving components 30 respectively drive the squeezing roller bodies 211, the first adhesive layer 212, and the second adhesive layer 213 of the two squeezing components 20 to move downward to provide a pressing force for the squeezing roller 21. In this way, the second adhesive layer 213 of the squeezing roller 21 of the two squeezing components 20 can squeeze the foil respectively, thereby achieving the squeezing out of the antioxidant liquid on both sides of the foil. In the process of squeezing the foil through the second adhesive layer 213 of the squeezing roller 21, the stress on the second adhesive layer 213 can be released by the first adhesive layer 212 of the squeezing roller 21, thereby achieving a buffering effect on the second adhesive layer 213, making it difficult for the second adhesive layer 213 to deform when subjected to a continuous large pressing force. Therefore, the antioxidant liquid on both sides of the foil can be fully and effectively squeezed out through the second adhesive layer 213, thereby improving production efficiency and extending the service life of the squeezing roller 21.

[0059] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
