Description

Technical Field

[0001] This utility model relates to the field of electroforming foil technology, and in particular to a pressing roller device for tightening electroforming foil. Background Technology

[0002] In existing electrolytic foil production, after the foil is prepared, it is wound onto a foil winding roller for easy collection and handling. To ensure the winding effect and prevent creases that could cause the foil to break, a pressure roller device is used to press the foil during winding. The reaction force of the existing pressure roller is usually achieved using a spring, which has the following problems:

[0003] 1. The final thickness of the foil on the foil winding roller is limited and relatively thin. If the thickness continues to increase, the reaction force given by the spring through the pressure roller will also increase, which can easily cause the foil to break and affect the quality. Therefore, the winding efficiency is low and the foil winding roller needs to be replaced frequently.

[0004] 2. The reaction force is difficult to control, which can easily lead to foil breakage and affect the quality of the foil;

[0005] 3. It is inconvenient to replace the foil rolling roller. Utility Model Content

[0006] This utility model provides a clamping roller device for tightening chemically formed foil, which aims to solve the problems of limited thickness, frequent root canal foil winding rollers, poor control of reaction force leading to foil breakage, and inconvenience in replacing foil winding rollers when using the above-mentioned foil winding clamping rollers.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A pressing roller device for forming foil includes a limiting post vertically disposed on the top of a bearing seat of a foil winding roller. Each limiting post is detachably provided with a limiting component. Each limiting component is slidably fitted with a sliding component in the vertical direction. The sliding components are arranged opposite to each other and a rotatable pressing component is clamped between the sliding components. The pressing component is supported on the foil winding roller and forms a pressing fit with the foil.

[0009] Preferably, the limiting post is vertically fixed at the middle position of the top of the bearing seat.

[0010] More preferably, the top of the bearing housing has a horizontal and flat structure.

[0011] Furthermore, the limiting component includes a fixed sleeve that is movably sleeved outside the limiting post. The fixed sleeve and the limiting post form a limiting fit. Both ends of the fixed sleeve are provided with limiting blocks concentrically and coaxially. The sliding component forms a limiting sliding fit with the outer wall of the fixed sleeve between the limiting blocks along the axial direction.

[0012] Furthermore, the sliding assembly includes a T-shaped sleeve, one end of which is slidably engaged with the fixed sleeve, and the other end of which is detachably fixedly engaged with the end of the pressing assembly.

[0013] Specifically, the T-shaped sleeve includes a vertical part and a horizontal part that are vertical and interconnected. The vertical part is movably sleeved on the outside of the fixed sleeve in a coaxial manner. The end of the clamping assembly is movably embedded in the horizontal part in a coaxial manner. A threaded hole is provided on the horizontal part along the radial direction of the horizontal part. A clamping screw is threaded in the threaded hole. The end of the clamping screw forms a clamping and fixing fit with the outer wall of the end of the clamping assembly.

[0014] More specifically, the clamping assembly includes a fixed shaft, the end of which is clamped and fixed to the horizontal part by a clamping screw, and a clamping roller is coaxially and limitly rotated at the middle position of the fixed shaft.

[0015] In detail, the pressing roller and the outermost foil sheet on the foil winding roller are linked together.

[0016] The beneficial effects of this utility model are:

[0017] The reaction force of this invention is always the gravity of the pressing component. The reaction force can be quickly adjusted by changing the pressing roller. In the process, the gravity of the pressing component is basically the dominant force of the reaction force, which ensures the stability of the force on the top of the foil and avoids the reaction force from increasing and breaking the foil.

[0018] The pressing component can automatically adjust its position via the sliding component. When the foil on the foil roll becomes thicker, the pressing component slides upward along the limiting component via the sliding component to automatically lift, avoiding an increase in reaction force and increasing the overall thickness of the wound foil, thus reducing the frequency of foil roll replacement.

[0019] Installation and disassembly are both convenient. During installation, select the appropriate clamping component and install it between the sliding components, and then align the limiting component with the limiting post and lower it. When disassembly is required, simply remove the device along with the limiting component, which facilitates the replacement of the foil roller. Attached Figure Description

[0029] The embodiments will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-4 As shown in the preferred embodiment 1, the pressing roller device for forming foil includes a limiting post 1 vertically disposed on the top of the bearing seat 5 of the foil winding roller 6. Each limiting post 1 is detachably provided with a limiting component 2. Each limiting component 2 is slidably fitted with a sliding component 3 in the vertical direction. The sliding components 3 are arranged opposite each other and a rotatable pressing component 4 is clamped between the sliding components 3. The pressing component 4 is supported on the foil winding roller 6 and forms a pressing fit with the foil.

[0031] The reaction force of this utility model is always the gravity of the pressing component 4. The reaction force can be quickly adjusted by replacing the pressing roller 42. In the process, the gravity of the pressing component 4 is basically the dominant force of the reaction force, ensuring the stability of the force on the top of the foil and avoiding the reaction force from increasing and breaking the foil.

[0032] The pressing component 4 can be automatically adjusted in position by sliding component 3. When the foil on the foil roll 6 becomes thicker, the pressing component 4 slides upward along the limiting component 2 through sliding component 3 to form an automatic lifting, which avoids the reaction force from increasing, while increasing the overall thickness of the wound foil and reducing the replacement frequency of foil roll 6.

[0033] Installation and disassembly are both convenient. During installation, select the appropriate clamping component 4 and install it between the sliding components 3, and then align the limiting component 2 with the limiting post 1 and lower it. When it needs to be removed, simply remove the device along with the limiting component 2, which facilitates the replacement of the foil roller 6.

[0034] The limiting component 2 includes a fixed sleeve 21 movably fitted outside the limiting post 1, forming a limiting fit with the limiting post 1. Both ends of the fixed sleeve 21 are concentrically and coaxially provided with limiting blocks 22. The sliding component 3 forms a limiting sliding fit with the outer wall of the fixed sleeve 21 between the limiting blocks 22 along the axial direction. The limiting blocks 22 ensure that the sliding component 3 slides only on the fixed sleeve 21. The entire device can be installed by fitting the fixed sleeve 21 onto the limiting post 1. The pressing component 4 automatically presses against the foil sheet at the top of the foil roller 6 by gravity.

[0035] The sliding component 3 includes a T-shaped sleeve 31, one end of which is slidably engaged with the fixed sleeve 21, and the other end of which is detachably fixedly engaged with the end of the pressing component 4.

[0036] The T-shaped sleeve 31 includes a vertical part 311 and a horizontal part 312 that are vertically connected to each other. The vertical part 311 is concentrically and coaxially movably sleeved on the outside of the fixed sleeve 21 to ensure sliding in the vertical direction. The end of the clamping assembly 4 is concentrically and coaxially movably embedded in the horizontal part 312. The horizontal part 312 is provided with a threaded hole 32 along the radial direction of the horizontal part 312. A clamping screw 33 is threaded in the threaded hole 32. The end of the clamping screw 33 forms a clamping and fixing fit with the outer wall of the end of the clamping assembly 4 to ensure the fixation of the fixed shaft 41 and facilitate disassembly.

[0037] The clamping assembly 4 includes a fixed shaft 41. The end of the fixed shaft 41 is clamped and fixed to the horizontal part 312 by a clamping screw 33. A clamping roller 42 is coaxially and limited to rotate in the middle position of the fixed shaft 41.

[0038] The pressing roller 42 is linked to the outermost foil sheet on the foil rolling roller 6. The edge of the foil sheet is pressed by the pressing roller 42, which also drives the pressing roller 42 to rotate around the fixed shaft 41, ensuring the uniformity and effectiveness of the pressing.

[0039] In a preferred embodiment 2, the limiting post 1 is vertically fixed at the top center of the bearing seat 5, ensuring the installation stability of the limiting assembly 2.

[0040] The top of the bearing housing 5 is a horizontal and flat structure, ensuring the installation stability of the limiting component 2.

[0041] As a preferred embodiment 3, the pressure roller 42 is available in various specifications, including various diameters and various masses, to facilitate selection according to actual conditions;

[0042] The fixed sleeve 21 also comes in various specifications, and the height of the fixed sleeve 21 must be greater than the sum of the final thickness of the foil roll 6 and the radius of the corresponding pressing roll 42, so as to ensure that the movement and pressing do not interfere with each other, avoid foil breakage, and also prevent the entire device from being lifted up, which would affect the pressing effect.

[0043] The working principle of this utility model:

[0044] The reaction force of this utility model is always the gravity of the pressing component 4. The reaction force can be quickly adjusted by replacing the pressing roller 42. In the process, the gravity of the pressing component 4 is basically the dominant force of the reaction force, ensuring the stability of the force on the top of the foil and avoiding the reaction force from increasing and breaking the foil.

[0045] The pressing component 4 can be automatically adjusted in position by sliding component 3. When the foil on the foil roll 6 becomes thicker, the pressing component 4 slides upward along the limiting component 2 through sliding component 3 to form an automatic lifting, which avoids the reaction force from increasing, while increasing the overall thickness of the wound foil and reducing the replacement frequency of foil roll 6.

[0046] Installation and disassembly are both convenient. During installation, select the appropriate clamping component 4 and install it between the sliding components 3, and then align the limiting component 2 with the limiting post 1 and lower it. When it needs to be removed, simply remove the device along with the limiting component 2, which facilitates the replacement of the foil roller 6.
