DETAILED DESCRIPTION

[0032] Example 1: Please refer to Figures 1 to 6 The embodiment of the present invention provides a shear roller 2 adjustment structure, which is mainly used to realize the rapid adjustment of the shear roller 2 to adapt to different film conveying. It specifically includes a shell 1 and four shear rollers 2. The four shear rollers 2 are respectively located on the left and right sides of the shell 1, and the four shear rollers 2 correspond to each other in twos. An adjustment component 3 is provided on the shell 1, and two bases 6 are rotatably installed on the adjustment component 3. A rotating component 4 is commonly provided between the adjusting component 3 and the base 6, and a limiting component 5 is commonly provided between the rotating component 4, the shell 1 and the base 6.

[0033] Among them, the shear roller 2 located at the bottom is placed on the base 6, and the shear roller 2 located at the top is placed on the limit assembly 5, and a gap is left between the upper and lower shear rollers 2 for the film to pass through. In the above structure, the adjustment assembly 3 can be used to adjust the gap between the two bases 6 in the left and right directions, and then adjust the gap between the shear rollers 2 on both sides to adapt to the use of films of different widths; the limit assembly 5 can be used to adjust the height of the upper shear roller 2 relative to the lower shear roller 2, and then adjust the gap between the upper and lower shear rollers 2 on the same side to adapt to the use of films of different thicknesses; the rotation assembly 4 can be used to adjust the angle of the two shear rollers 2 on the same side based on the plane, and then adjust the angle between the shear roller 2 and the moving direction of the film, so that the shear roller 2 generates a lateral pulling force on the film, thereby achieving the purpose of improving the flatness of the film.

[0034] Furthermore, the rotating assembly 4 is sleeved outside the adjusting assembly 3, and the limiting assembly 5 is sleeved outside the rotating assembly 4. The adjusting assembly 3, the rotating assembly 4 and the adjusting assembly 3 are just placed on the housing 1, but the three will not interfere with each other. Therefore, when adjusting, only one side of the housing 1 is needed to complete the spacing adjustment between the shear rollers 2 on both sides, the spacing adjustment between the upper and lower shear rollers 2 on the same side, and the angle adjustment of the two shear rollers 2 on the same side, making the adjustment method simpler and less burdensome.

[0035] Reference Figures 2 to 5 In this embodiment, preferably: the adjustment component 3 includes a long rod 301 rotatably matched with the shell 1, and two sliders 302 are threadedly sleeved on the outer surface of the long rod 301, and a support rod 303 rotatably matched with the bottom surface of the base 6 is fixedly installed on the top of the slider 302; when the long rod 301 is rotated, the two sliders 302 can be driven to move closer / away from each other, and then the two bases 6 can be driven to move closer / away from each other through the support rod 303, thereby realizing the relative approach / distance of the shear rollers 2 on both sides, and completing the corresponding adaptation with the film width.

[0036] In the above structure, the outer surface of the long rod 301 is provided with two opposite sections of threads, and the two sliders 302 are respectively arranged on the two opposite sections of threads, so as to realize the relative approach / distance of the two sliders 302 when the long rod 301 rotates; the two sliders 302 drive the base 6 and the shear roller 2 on the base 6 to move synchronously through the support rod 303, and the base 6 drives the rotating component 4 and the limiting component 5 to adapt to the movement, so that the upper and lower shear rollers 2 on the same side can move left and right synchronously.

[0037] Reference Figures 2 to 6 In this embodiment, preferably: the rotating assembly 4 includes a first sleeve 401 rotatably mounted outside the long rod 301 and a second bevel gear 404 rotatably mounted outside the support rod 303, the second bevel gear 404 is fixedly mounted on the bottom surface of the base 6, and the interior of the first sleeve 401 is equipped with an inner sleeve 402 rotatably connected to the side wall of the slider 302 through a key shaft assembly, and the outer surface of the inner sleeve 402 is fixedly equipped with a first bevel gear 403 transmission-connected to the second bevel gear 404.

[0038] Among them, the rotation of the long rod 301 will not interfere with the first sleeve 401. When the first sleeve 401 rotates, it can drive the inner sleeve 402 to rotate synchronously, and the inner sleeve 402 can slide back and forth left and right along the axial direction of the long rod 301 based on the first sleeve 401, and the inner sleeve 402 will move left and right synchronously with the slider 302; when the inner sleeve 402 rotates, it can drive the first bevel gear 403 to rotate, and the first bevel gear 403 can drive the base 6 to deflect synchronously through the second bevel gear 404. On the one hand, the base 6 drives the shear roller 2 below to deflect, and on the other hand, it drives the shear roller 2 above to deflect through the limit assembly 5, so that the deflection of the upper and lower shear rollers 2 is synchronized.

[0039] Reference Figures 2 to 6 In this embodiment, preferably: the limiting assembly 5 includes a second sleeve 501 rotatably mounted on the shell 1 and a bracket 502 slidably mounted on the base 6, the bracket 502 is for corresponding placement of the shear roller 2 above, the outer surface of the second sleeve 501 is installed with a sleeve 503 through a key shaft assembly, the outer surface of the sleeve 503 is fixedly installed with a circular gear 504, and the surface of the bracket 502 is fixedly installed with a vertical rack 505 that is transmission-connected to the circular gear 504.

[0040] Among them, the second sleeve 501 is also rotatably mounted outside the first sleeve 401, and the rotation of the two does not interfere with each other. When the second sleeve 501 rotates, the outer sleeve 503 can drive the circular gear 504 to rotate, thereby making the vertical rack 505 drive the bracket 502 and the shear roller 2 located above to rise and fall accordingly; when the second sleeve 501 rotates, the outer sleeve 503 can be driven to rotate synchronously, and the outer sleeve 503 can slide back and forth left and right along the axial direction of the long rod 301 based on the second sleeve 501.

[0041] It can be understood that the matching and placement of the second sleeve 501 and the outer sleeve 503 are the same as the matching and placement of the first sleeve 401 and the inner sleeve 402, except that the inner sleeve 402 and the outer sleeve 503 are respectively based on different directions of the first sleeve 401 and the second sleeve 501. At the same time, a certain distance is left between the vertical rack 505 and the circular gear 504, so that after the bracket 502 drives the vertical rack 505 to deflect a certain angle, the vertical rack 505 can still maintain a meshing transmission state with the circular gear 504 without disengagement; because the angle adjustment of the clamping roller is a small range adjustment, the above-mentioned spacing can be easily realized.

[0042] When the base 6 slides back and forth along the axial direction of the long rod 301, the bracket 502 and the two shear rollers 2 can be driven to move synchronously, and the bracket 502 drives the vertical rack 505 to move synchronously. At this time, in order to ensure the meshing transmission of the circular gear 504 and the vertical rack 505, a clamping seat 601 that abuts against the circular gear 504 can be fixedly installed on the side wall of the bracket 502, and the inside of the clamping seat 601 is elastically connected to the abutment blocks that abut against the ends of the circular gear 504 on both sides through a spring, so that when the bracket 502 moves, the clamping seat 601, the spring and the abutment blocks can drive the circular gear 504 to move synchronously, and then the circular gear 504 can move synchronously left and right with the slider 302, and maintain a meshing transmission state with the vertical rack 505.

[0043] Alternatively, the circular gear 504 is rotatably connected to the first bevel gear 403 via a bearing, so that when the first bevel gear 403 moves left and right with the inner sleeve 402, it can also drive the circular gear 504 to move left and right synchronously, and the setting of the bearing ensures that the rotation of the first bevel gear 403 and the circular gear 504 do not interfere with each other.

[0044] Furthermore, the bracket 502 and the base 6 are slidably matched up and down. Specifically, the side wall of the bracket 502 is provided with a dovetail groove 506, and the side wall of the base 6 protrudes toward the bracket 502 and is formed with a dovetail block, which is slidably engaged in the dovetail groove 506, so that the bracket 502 can slide up and down along the base 6, and the rotation of the base 6 can drive the bracket 502 to rotate synchronously. Of course, the dovetail groove 506 and the dovetail block can also be replaced with existing T-shaped, polygonal or circular shapes, as long as they can meet the above-mentioned movement process.

[0045] It should be noted that the ends of the long rod 301, the first sleeve 401 and the second sleeve 501 away from the slider 302 are all provided with handles for quick adjustment of the long rod 301, the first sleeve 401 and the second sleeve 501; and the long rod 301, the first sleeve 401 and the second sleeve 501 are sequentially sleeved, and the structure is simple and clear. Of course, in actual application, the handle can also be replaced by an existing motor transmission structure, as long as the long rod 301, the first sleeve 401 and the second sleeve 501 can rotate accordingly.

[0046] It should also be noted that a circular hole 101 is opened through the surface of the shell 1 for accommodating the long rod 301, the first sleeve 401 and the second sleeve 501. The diameter of the circular hole 101 is equal to the sum of the diameters of the long rod 301, the first sleeve 401 and the second sleeve 501. At this time, the long rod 301, the first sleeve 401 and the second sleeve 501 can be stably installed on the shell 1.

[0047] When in use, the film first passes through the outer surface of the lower shear roller 2, and then the long rod 301 is rotated to drive the two sliders 302 to approach each other through two opposite threads. The two sliders 302 drive the inner sleeve 402, the support rod 303 and the base 6 to move synchronously. The base 6 drives the lower shear roller 2, the bracket 502 and the upper shear roller 2 to move synchronously, so that the shear rollers 2 on both sides are adapted to the width of the film. When the left and right positions of the shear rollers 2 on both sides are adjusted appropriately, the first sleeve 401 is rotated again, so that it drives the base 6 to deflect through the inner sleeve 402, the first bevel gear 403 and the second bevel gear 404, and the base 6 drives the lower shear roller 2 to rotate synchronously and drives the upper shear roller 2 to rotate synchronously through the bracket 502, so as to adjust the angle between the shear roller 2 and the film conveying direction. When the angle is adjusted appropriately, the second sleeve 501 is rotated again, so that it drives the bracket 502 to move up and down through the outer sleeve 503, the circular gear 504 and the vertical rack 505, so as to adjust the spacing between the upper and lower shear rollers 2 on the same side, so as to make the spacing in the up and down direction adapted to the film.

[0048] To summarize, through the coordination of the long rod 301, the first sleeve 401, the base 6 and the second sleeve 501 and other structures, the spacing between the left and right shear rollers 2 can be adjusted so that the spacing size in the left and right directions is adapted to the width size of the film, and the spacing between the upper and lower shear rollers 2 on the same side can be adjusted so that the spacing size in the upper and lower directions is adapted to the thickness size of the film. The two shear rollers 2 on the same side can also rotate synchronously, thereby adjusting the angle between the shear roller 2 and the film conveying direction; the multi-stage adjustment can be effectively applied to the conveying of films with different parameters, and can effectively improve the flatness of the film after production.

[0049] The overall adjustment method is simple and less burdensome. The long rod 301, the first sleeve 401 and the second sleeve 501 are sequentially mounted and adjusted in sequence, which can effectively reduce the possibility of misoperation by the staff, and the adjustment positions are gathered on one side of the shell 1, so that the staff can achieve multi-level adjustment when they are on one side of the shell 1, and can also effectively reduce the labor burden, with higher overall efficiency and higher practicality.

[0050] As a further improvement of this embodiment: the lower shearing roller 2 can be improved to be movable, so that the upper and lower shearing rollers 2 on the same side are relatively close to / far away from each other. At this time, the bracket 502 of the limiting component 5 can be designed to be two and both are slidably matched with the base 6, and the two shearing rollers 2 on the same side can be placed on the two brackets 502 respectively, and the two brackets 502 are fixedly installed with vertical racks 505 that are transmission-connected to the circular gear 504, and the vertical racks 505 are symmetrical based on the front and back of the circular gear 504, so that when the circular gear 504 rotates, the two vertical racks 505 move in opposite directions up and down, thereby making the upper and lower shearing rollers 2 on the same side relatively close to / far away from each other. The above design does not have any restrictions on the initial position of the film, so that the film can pass through the lower shearing roller 2 quickly and smoothly.

[0051] Example 2: Please refer to Figures 1 to 9 On the basis of the first embodiment, considering that the adjustment of the shear rollers 2 on the left and right sides needs to be implemented on both sides of the shell 1, it is impossible to complete the synchronous adjustment of the upper and lower spacing and the deflection angle on one side, so the workload is still large and there may be certain differences in the adjustment on both sides.

[0052] To this end, a first transmission assembly 7 is commonly provided between the two inner sleeves 402 and the shell 1, and a second transmission assembly 8 is commonly provided between the two second sleeves 501 and the shell 1. The first transmission assembly 7 is used to realize the synchronous rotation of the two inner sleeves 402 and the two first bevel gears 403, thereby realizing the synchronous rotation of the two bases 6; the second transmission assembly 8 is used to realize the synchronous rotation of the two second sleeves 501 and the two outer sleeves 503, thereby realizing the synchronous up and down movement of the two vertical racks 505 and the two brackets 502.

[0053] Reference Figure 7 and Fig. 9In this embodiment, preferably, the first transmission assembly 7 includes a column fixedly mounted on the housing 1, a telescopic rod 701 is slidably mounted on the surface of the column, and both ends of the telescopic rod 701 are connected to the two inner sleeves 402 through a first belt drive 702. The telescopic rod 701 can slide left and right based on the column, and the first belt drive 702 is adapted to the movement of the inner sleeve 402 through the telescopic rod 701, and the first belt drive 702 allows the rotation of the inner sleeve 402 on one side to be transmitted to the inner sleeve 402 on the other side.

[0054] Reference Figure 7 and Fig. 9 In this embodiment, preferably, the second transmission assembly 8 includes a cross bar 801 rotatably mounted on the housing 1, and both ends of the cross bar 801 are connected to the two second sleeves 501 through a second belt drive 802. When the second sleeve 501 on one side rotates, the second sleeve 501 on the other side can be driven to rotate synchronously through the second belt drive 802 and the cross bar 801.

[0055] It should be noted that the first belt drive 702 and the second belt drive 802 are both belt drives or chain drives, and the corresponding pulleys and sprockets can be fixedly mounted on the telescopic rod 701, the inner sleeve 402, the cross bar 801 and the second sleeve 501, respectively, which are all existing mature technologies and are not described in detail here. When the circular gear 504 and the first bevel gear 403 are rotated and matched through the bearing, the first belt drive 702 is located between the first bevel gear 403 and the slider 302.

[0056] When in use, through the structures such as the long rod 301, the first sleeve 401 and the second sleeve 501, the spacing between the left and right shear rollers 2 can be adjusted, the spacing between the upper and lower shear rollers 2 on the same side can be adjusted, and the two shear rollers 2 on the same side can be driven to rotate synchronously. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the first sleeve 401 rotates to drive the inner sleeve 402 to rotate, the inner sleeve 402 drives the first bevel gear 403 to rotate on the one hand, and drives the inner sleeve 402 on the other side to rotate synchronously through the first belt transmission 702 and the telescopic rod 701 on the other hand, thereby causing the two bases 6 to deflect synchronously. When the second sleeve 501 rotates, it drives the outer sleeve 503 to rotate on the one hand, and drives the second sleeve 501 on the other side to rotate synchronously through the second transmission and the cross bar 801 on the other hand, thereby realizing the synchronous adjustment of the rotation of the left and right bases 6 and the synchronous adjustment of the upper and lower positions of the shear rollers 2.

[0057] Compared with the first embodiment, through the cooperation of the structures such as the inner sleeve 402, the second sleeve 501, the cross bar 801 and the telescopic rod 701, the synchronous adjustment of the rotation of the left and right bases 6 and the synchronous adjustment of the upper and lower positions of the shear rollers 2 can be achieved on any side of the shell 1, thereby ensuring the synchronization and consistency of the adjustment process on both sides, and further ensuring the conveying effect of the film. The overall design is combined with the setting of the inner sleeve 402 and the second sleeve 501, and there is no need to adjust the shear rollers 2 on both sides of the shell 1, which can correspondingly improve the adjustment efficiency of the shear rollers 2, and can further reduce the labor burden of the staff, and has stronger applicability.

[0058] Example 3: Please refer to Figures 1 to 10 On the basis of the second embodiment, considering that the film passes between the upper and lower shear rollers 2, and the shear rollers 2 are passively rotated by the moving profile of the film, and when some ultra-thin films pass through the shear rollers 2, the passive rotation resistance of the shear rollers 2 is large, affecting the stability of the ultra-thin film transportation.

[0059] To this end, the shearing roller 2 is improved: the shearing roller 2 now includes a cover 201 and a roller shaft 202 rotatably arranged in the cover 201, the roller shaft 202 is detachably mounted on the base 6 or the bracket 502 by bolts, a brushless coil 203 is fixedly mounted on the outer surface of the roller shaft 202, and a permanent magnet 204 corresponding to the brushless coil 203 is fixedly mounted on the inner wall of the cover 201, and the permanent magnet 204 is annularly covered outside the brushless coil 203. In the above structure, by energizing the brushless coil 203, the permanent magnet 204 can drive the cover 201 to rotate actively.

[0060] One side of the roller 202 is relatively fixed to the base 6 or the bracket 502 by bolts, and the cover 201 is sleeved outside the roller 202, and bolts are also installed on the other side of the roller 202 to achieve relative fixation of the cover 201 on the roller 202.

[0061] When in use, through the structures such as the long rod 301, the first sleeve 401 and the second sleeve 501, the spacing between the left and right shear rollers 2 can be adjusted, the spacing between the upper and lower shear rollers 2 on the same side can also be adjusted, and the two shear rollers 2 on the same side can also be driven to rotate synchronously; through the structures such as the inner sleeve 402, the second sleeve 501 and the telescopic rod 701, the synchronization and consistency of the adjustment process on both sides can be ensured. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that after the left and right positions, the upper and lower positions and the rotation angle of the shear roller 2 are adjusted, the brushless coil 203 can be energized, and the permanent magnet 204 can be used to drive the cover 201 to rotate actively to ensure the stability of film transportation.

[0062] Compared with the second embodiment, the roller 202, the cover 201, the permanent magnet 204 and the brushless coil 203 are coordinated to make the upper and lower corresponding shear rollers 2 rotate actively, avoiding the passive resistance of the shear roller 2 affecting the stability of film transportation, and can be effectively applied to existing ultra-thin films. The overall design is combined with the setting of the shear roller 2, and the disassembly, replacement and maintenance of the shear roller 2 are still very convenient, meeting more needs in actual use.
