Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil, in particular to a polytetrafluoroethylene gasket device for rapid replacement of a foil production machine and a foil production machine. Background Art

[0002] At present, in the production process of electrolytic copper foil, PTFE gaskets play a very important role - sealing the cathode edge. When the foil machine is running, the PTFE gasket will wear and tear in contact with the cathode and O-ring in a strong acid and high temperature environment. It needs to be replaced in time to achieve the sealing effect. Otherwise, the single copper is easy to be plated into the right-angle edge, making it impossible to peel the copper foil normally. However, in the current production process, replacing the PTFE gasket requires the foil machine to be shut down, and a large number of screws fixing the PTFE gasket and the anode tank steel plate of the foil machine need to be removed. When installing the PTFE gasket, all these screws need to be reset, which takes a long time to stop, seriously affecting production efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] Furthermore, in the exemplary embodiments, since the same reference numerals denote the same components having the same structure or the same steps of the same method, if one embodiment is exemplarily described, only structures or methods different from the described embodiment are described in other exemplary embodiments.

[0023] Throughout the specification and claims, when a component is described as being “connected” to another component, the component may be “directly connected” to the other component, or “electrically connected” to the other component through a third component. In addition, unless explicitly described to the contrary, the term “include” and its corresponding terms should be understood to include only the components described, and should not be understood to exclude any other components.

[0024] Figure 1 FIG. 1 is a schematic structural diagram of a polyfluoroethylene gasket device for quick replacement of a foil production machine provided by an exemplary embodiment of the present application. Figure 2 The figure shows a polytetrafluoroethylene gasket device for quick replacement of a foil machine provided by another exemplary embodiment of the present application. Figure 3 This application is shown Figure 2 A partial enlarged view of part B, such as Figure 1-Figure 3 As shown, a polyfluoroethane gasket device 2 for quick replacement of a raw foil machine, the raw foil machine includes an anode tank steel plate 1, and a groove is provided on the anode tank steel plate 1. The polyfluoroethane gasket device 2 for quick replacement of the raw foil machine includes: a bottom ring 21, the shape of the bottom ring 21 is the same as the groove on the anode tank steel plate 1, the bottom ring 21 is used to be inserted into the groove and engage with the anode tank steel plate 1; a polyfluoroethane gasket 22, the polyfluoroethane gasket 22 is connected to the bottom ring 21, and the polyfluoroethane gasket 22 is fixed to the anode tank steel plate 1 through the bottom ring 21.

[0025] The anode tank steel plate 1 is an arc-shaped steel plate, so in the prior art, multiple screws are required to fix the polytetrafluoroethylene gasket 22 on the anode tank steel plate 1. However, in this embodiment, a bottom ring 21 is prefabricated on the basis of the polytetrafluoroethylene gasket 22, and the bottom ring 21 forms a connection structure between the anode tank steel plate 1 and the polytetrafluoroethylene gasket 22. The polytetrafluoroethylene gasket 22 is pre-connected to the bottom ring 21 by means of bolts 25 or snaps. When the polytetrafluoroethylene gasket 22 needs to be replaced, the bottom ring 21 on the original anode tank steel plate 1 is pulled out from the side of the anode tank, or when the bottom ring 21 is not installed on the anode tank steel plate 1, the bottom ring 21 is directly inserted into the groove on the anode tank steel plate 1, thereby fixing the polytetrafluoroethylene gasket 22 on the anode tank steel plate 1, and the fixing process is advanced. During the replacement process, a large number of screw fixing processes are not required, thereby reducing the downtime installation time of the foil machine. That is, the installation process of the polytetrafluoroethylene gasket 22 is changed to an insertion and snap-fitting process, which is fast and efficient.

[0026] In one embodiment, if Figure 3 As shown, the polytetrafluoroethylene gasket device 2 for quick replacement of the foil machine may also include: a connecting block 23, the connecting block 23 is located between the bottom ring 21 and the polytetrafluoroethylene gasket 22; a connecting piece 24, the connecting piece 24 is located on the top of the connecting block 23, one end of the connecting piece 24 is connected to the connecting block 23, and the other end of the connecting piece 24 is connected to the top of the bottom ring 21.

[0027] A connecting block 23 is added between the bottom ring 21 and the PTFE gasket 22. The length of the connecting block 23 can be the same as the length of the PTFE gasket 22. The length of the connecting block 23 is less than or equal to the length of the bottom ring 21, but the width of the connecting block 23 is less than the width of the PTFE gasket 22. Since the bottom ring 21 and the PTFE gasket 22 need to be inserted into the arc-shaped anode tank steel plate 1, adding the connecting block 23 can enhance the connection strength and stability between the bottom ring 21 and the PTFE gasket 22, and enhance the tensile, shear and torsion resistance of the connection point by providing additional contact area and more evenly distributed stress. And the connecting block 23 can help share the load or force between the bottom ring 21 and the PTFE gasket 22. By introducing the connecting block 23 at the connection point, it can bear part or all of the force, reduce the load of the object itself, and thus reduce the stress and possible damage of the material. The connecting piece 24 is located at the top of the connecting block 23, that is, the extraction and insertion position of the bottom ring 21. When the bottom ring 21 is inserted into the groove on the anode tank steel plate 1 and the bottom ring 21 and the anode tank steel plate 1 are fixed, the connecting piece 24 can be pressed between the anti-escape block and the bottom ring 21 to further increase the connection stability of the bottom ring 21 and the polytetrafluoroethylene gasket 22.

[0028] In one embodiment, if Figure 3 As shown, the bottom ring 21 , the connecting block 23 and the polytetrafluoroethylene gasket 22 may be connected by at least one bolt 25 , and the at least one bolt 25 passes through the bottom ring 21 , the connecting block 23 and the polytetrafluoroethylene gasket 22 .

[0029] Before replacing the PTFE gasket 22, the bottom ring 21, the connecting block 23 and the PTFE gasket 22 are connected by at least one bolt 25. When replacing, the connected bottom ring 21 can be directly inserted into the groove of the anode tank steel plate 1, so that part of the installation time can be advanced and the downtime installation time of the foil machine can be reduced. Since the bottom ring 21, the connecting block 23 and the PTFE gasket 22 will also become arc-shaped after being inserted into the anode tank steel plate 1, multiple bolts 25 are required to fix them to ensure the connection stability between the bottom ring 21, the connecting block 23 and the PTFE gasket 22. The bottom ring 21, the connecting block 23 and the PTFE gasket 22 are connected by bolts 25, so that the components can be quickly disassembled and connected, and a single replacement can be performed when any of the components has a problem. And the bottom ring 21 can be reused repeatedly. After the used bottom ring 21 is pulled out, the PTFE gasket 22 connected to the bottom ring 21 is replaced to form a new PTFE gasket 22 device, which can be put back into use in the foil machine. The bolt 25 passes through the connecting block 23, the PTFE gasket 22 and up to the bottom ring 21. The bolt 25 may or may not pass through the bottom ring 21, but it needs to be connected to the bottom ring 21 at least and not exceed the bottom surface of the bottom ring 21 (the side of the bottom ring 21 close to the anode tank steel plate 1), otherwise it will affect the engagement between the bottom ring 21 and the anode tank steel plate 1.

[0030] In one embodiment, if Figure 3As shown, the polytetrafluoroethylene gasket device 2 for quick replacement of the foil machine may further include: a buffer rubber strip 26 , the buffer rubber strip 26 is located between the bottom ring 21 and the polytetrafluoroethylene gasket 22 , and the buffer rubber strip 26 is engaged on the bottom ring 21 .

[0031] In addition to the connecting block 23, a buffer rubber strip 26 is provided between the bottom ring 21 and the polytetrafluoro gasket 22. The length of the buffer rubber strip 26 can be the same as the length of the polytetrafluoro gasket 22. The length of the buffer rubber strip 26 is less than or equal to the length of the bottom ring 21, but the width of the buffer rubber strip 26 is less than the width of the polytetrafluoro gasket 22. The buffer rubber strip 26 and the connecting block 23 are installed in parallel between the bottom ring 21 and the polytetrafluoro gasket 22. There is no connection between the buffer rubber strip 26 and the polytetrafluoro gasket 22. The buffer rubber strip 26 is clamped on the bottom ring 21. When the polytetrafluoro gasket 22 is connected to the bottom ring 21, the part of the buffer rubber strip 26 protruding from the bottom ring 21 is squeezed, and a buffer is formed by the part. The buffer rubber strip 26 is made of soft and elastic material. The buffer rubber strip 26 can absorb and reduce the impact and vibration between the bottom ring 21 and the polytetrafluoro gasket 22, and can reduce the contact noise and vibration transmission between the bottom ring 21 and the polytetrafluoro gasket 22. The buffer rubber strip 26 is connected to the bottom ring 21 by insertion or snap-on connection, which is convenient for disassembly and connection. When any component of the bottom ring 21 or the buffer rubber strip 26 needs to be replaced, a single replacement can be performed in a targeted manner, and the component without problems can continue to be put into use, saving the use cost.

[0032] Figure 4 FIG. 1 is a schematic diagram of the structure of a buffer rubber strip provided by an exemplary embodiment of the present application. Figure 3 and Figure 4 As shown, the buffer rubber strip 26 includes a first portion 261 close to the bottom ring 21 and a second portion 262 close to the polytetrafluoroethylene gasket 22. The first portion 261 is engaged in the bottom ring 21, and the second portion 262 is higher than the bottom ring 21 and contacts the polytetrafluoroethylene gasket 22. A triangular gap 263 is provided on the side of the first portion 261 close to the bottom ring 21.

[0033] A connection groove is provided on one side of the bottom ring 21 near the buffer PTFE gasket 22. The buffer rubber strip 26 can be connected in the connection groove by insertion. Based on the elastic characteristics of the buffer rubber strip 26, it can also be snapped into the connection groove by snapping. The part of the buffer rubber strip 26 snapped into the bottom ring 21 is the first part 261. The first part 261 can be designed as a trapezoid, wherein the long side of the parallel sides in the trapezoid is close to the bottom ring 21, and the short side of the parallel sides in the trapezoid is close to the PTFE gasket 22. Since the bottom side is long and the top side is short, and the shape of the connection groove is the same as that of the buffer rubber strip 26, this shape can prevent the buffer rubber strip 26 from escaping from the bottom ring 21. The second part 262 is higher than the bottom ring 21, and the thickness of the second part 262 is greater than the thickness of the connecting block 23. When the PTFE gasket 22 is connected to the bottom ring 21, the second part 262 will be squeezed, and the second part 262 will provide a buffering effect between the PTFE gasket 22 and the bottom ring 21. A triangular gap 263 is provided on one side of the first portion 261 close to the bottom ring 21. By providing the gap, the buffer rubber strip 26 can better absorb and disperse the impact force. When an external impact acts on the buffer rubber strip 26, the gap can allow the buffer rubber strip 26 to elastically deform when subjected to force, thereby reducing the transmission of the impact force to the connected object. This elastic buffering effect can protect the connected object from excessive impact force and damage. Providing the gap can also increase the flexibility and deformability of the buffer rubber strip 26. The buffer rubber strip 26 can deform more freely and adapt to objects of different shapes when subjected to force. This flexibility can improve the adaptability and application range of the buffer rubber strip 26, so that it can be suitable for connection requirements of different shapes and sizes.

[0034] In one embodiment, if Figure 4 As shown, the first portion 261 of the buffer rubber strip 26 is a trapezoid, the long side of the parallel sides of the trapezoid is close to the bottom ring 21, the short side of the parallel sides of the trapezoid is close to the polytetrafluoroethylene gasket 22, and the second portion 262 of the buffer rubber strip 26 is a triangle.

[0035] The first part 261 of the buffer rubber strip 26 is a trapezoid, wherein the long side of the parallel sides in the trapezoid is close to the bottom ring 21, and the short side of the parallel sides in the trapezoid is close to the polytetrafluoroethylene gasket 22. Since the bottom side is long and the top side is short, and the shape of the connecting groove is the same as that of the buffer rubber strip 26, this shape can prevent the buffer rubber strip 26 from escaping from the bottom ring 21. The second part 262 is designed to be a triangle. When the polytetrafluoroethylene gasket 22 is connected to the bottom ring 21, the second part 262 will be squeezed to tilt the triangle, so that there are gaps on the side of the second part 262 close to the polytetrafluoroethylene gasket 22 and the side close to the bottom ring 21, so that the impact force can be better absorbed and dispersed.

[0036] Figure 5 This application is shown Figure 1 A partial enlarged view of part A, such as Figure 1 and Figure 5As shown, the polytetrafluoroethylene gasket device 2 for quick replacement of the foil machine may also include: an anti-slip block 27, the anti-slip block 27 is located at the top of the bottom ring 21, the length of the anti-slip block 27 is greater than the length of the longest side of the bottom ring 21, the anti-slip block 27 is connected to the anode tank steel plate 1 by bolts, and the anti-slip block 27 is used to prevent the bottom ring 21 from slipping out of the groove on the anode tank steel plate 1.

[0037] The anti-escape block 27 is located on the side where the bottom ring 21 rotates from the cathode roller of the foil machine, and the bottom ring 21 is inserted and pulled out from here. Therefore, in order to prevent the bottom ring 21 from being brought out of the anode slot steel plate 1 when the cathode moves, an anti-escape block 27 is set to fix the bottom ring 21. The trapezoidal shape of the bottom ring 21 prevents the bottom ring 21 from being escaped from the front of the anode slot steel plate 1. The anti-escape block 27 is set to prevent the bottom ring 21 from being escaped from the side of the anode slot steel plate 1. Therefore, the bottom ring 21 is limited in multiple directions to reduce the probability of the bottom ring 21 being escaped from the anode slot steel plate 1 when the cathode moves.

[0038] In one embodiment, the groove of the anode tank steel plate includes a trapezoidal groove, the bottom ring includes a trapezoidal bottom ring, the long sides of the parallel sides of the trapezoidal bottom ring are close to the anode tank steel plate, and the short sides of the parallel sides of the trapezoidal bottom ring are close to the polytetrafluoroethylene gasket.

[0039] The long side of the parallel sides in the trapezoidal bottom ring is close to the anode slot steel plate, and the short side of the parallel sides is close to the PTFE gasket. Since the bottom side is long and the top side is short, and the shape of the groove of the anode slot steel plate is the same as that of the bottom ring, the bottom ring can be prevented from coming out of the anode slot steel plate. The trapezoidal shape of the bottom ring prevents the bottom ring from coming out from the front of the anode slot steel plate, and the anti-coming-out block prevents the bottom ring from coming out from the side of the anode slot steel plate. Therefore, the bottom ring is limited in multiple directions to reduce the probability of the bottom ring coming out of the anode slot steel plate when the cathode moves.

[0040] In one embodiment, the PTFE gasket device for quick replacement of the foil machine also includes: a limit block, which is located on the side of the groove of the anode tank steel plate close to the PTFE gasket, and the limit block is used to prevent the bottom ring from escaping from the groove on the anode tank steel plate.

[0041] In addition to setting a trapezoidal shape to prevent the bottom ring from escaping from the front side of the anode tank steel plate, a limit block can also be set on the side of the groove of the anode tank steel plate close to the polytetrafluoroethylene gasket to limit the bottom ring from escaping from the front side of the anode tank steel plate. After setting the limit block, the shape of the bottom ring cross-section can be set to other shapes such as square and rectangle.

[0042] According to another aspect of the utility model, a foil machine provided by one embodiment of the utility model includes: an anode tank steel plate, on which a groove is provided; and a polytetrafluoroethylene gasket device for quick replacement of the foil machine as in any of the above embodiments; wherein the polytetrafluoroethylene gasket device for quick replacement of the foil machine cooperates with the groove of the anode tank steel plate.

[0043] The anode tank steel plate is an arc-shaped steel plate, so in the prior art, multiple screws are required to fix the PTFE gasket on the anode tank steel plate. However, in this embodiment, a bottom ring is prefabricated on the basis of the PTFE gasket, and the bottom ring forms a connection structure between the anode tank steel plate and the PTFE gasket. The PTFE gasket is pre-connected to the bottom ring by bolts or snaps. When the PTFE gasket needs to be replaced, the bottom ring on the original anode tank steel plate is pulled out from the side of the anode tank, or when the bottom ring is not installed on the anode tank steel plate, the bottom ring is directly inserted into the groove on the anode tank steel plate, thereby fixing the PTFE gasket on the anode tank steel plate, advancing the fixing process, and eliminating the need for a large number of screw fixing processes during the replacement process, thereby reducing the downtime and installation time of the foil machine. That is, the installation process of the PTFE gasket is changed to an insertion and snap-fit ​​process, which is fast and efficient.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
