Description

Technical Field

[0001] This utility model belongs to the field of diaphragm processing equipment technology, specifically relating to a diaphragm cutting module and device. Background Technology

[0002] Membranes (or membrane materials) are widely used in various fields such as industry, electronics, optics, and medicine, including new energy storage, robot motors, new energy vehicles, valve control, and optical equipment. In industrial production, membranes are formed using various membrane-making methods, such as dry membrane formation in the lithium battery industry. After forming, they need to undergo edge trimming or slitting operations to remove irregular edges, or be cut to a predetermined width for further processing and use.

[0003] In existing technologies, during diaphragm cutting, corresponding cutters are installed on the frame based on the diaphragm's feed channel, and the diaphragm is cut simultaneously with the feed. However, for the production of diaphragms of different widths, it is necessary to change the cutter assembly, disassemble the cutter mechanism, replace relevant parts, and adjust the cutter position or spacing to control the width of the cut diaphragm and thus meet the production process parameters. However, disassembling the cutter mechanism is time-consuming and labor-intensive, easily damages the cutters, introduces minor defects, results in a high frequency of cutter failure, and increases spare parts costs. Utility Model Content

[0004] The present invention aims to provide a film cutting module and device that can conveniently adjust the cutting position of the cutter relative to the feed film without disassembly; the present invention is achieved through the following technical solution.

[0005] In a first aspect, this utility model provides a film cutting module, characterized in that it includes a base plate, a support, a first cutting assembly, and a second cutting assembly; the first cutting assembly includes a feed roller and an annular groove disposed at a predetermined position along the axial direction of the feed roller; the second cutting assembly includes a cutting shaft and an annular cutter disposed on the cutting shaft and aligned with the annular groove; the feed roller and the cutting shaft are parallel to each other and rotatably disposed on the support, forming a feed channel for feeding the film between the feed roller and the cutting shaft; the base plate is fixedly disposed, and the support is disposed on the base plate in a sliding and adjustable manner, parallel to the axial direction of the feed roller.

[0006] The diaphragm cutting module provided by the above technical solution forms a material feeding channel for the diaphragm by arranging a feeding roller and a cutting shaft in parallel on the support. While the diaphragm is feeding, the annular groove of the first cutting assembly and the annular cutter of the second cutting assembly cooperate to cut the diaphragm. More importantly, the diaphragm's travel path is fixed relative to the base plate during feeding. By sliding and adjusting the position of the support relative to the base plate, the cutting position of the annular groove and the annular cutter relative to the diaphragm can be adjusted, thereby trimming at least one side (left or right side) of the diaphragm or cutting the diaphragm into sub-diaphragms of a predetermined width, improving cutting efficiency while effectively protecting the equipment.

[0007] As a preferred technical solution, the film cutting module further includes a sliding plate; a slide rail is provided on the base plate, the sliding plate is slidably mounted on the slide rail by a slider, and the bracket is fixedly mounted on the sliding plate.

[0008] The advantages of the above-mentioned preferred solution are that, compared with the method of directly sliding the bracket on the base plate, the method of indirectly connecting the bracket through the sliding plate can simplify the design of the bracket and facilitate its processing and maintenance.

[0009] As a preferred technical solution, the bracket includes a horizontal plate and a left support plate and a right support plate disposed at both ends of the horizontal plate. The two ends of the feed roller and the cutter shaft are respectively rotatably disposed on the left support plate and the right support plate. The horizontal plate is clamped to the sliding plate by clamping components disposed on the front and rear sides.

[0010] The advantages of the above preferred solution are that the cross plate of the bracket is clamped to the sliding plate by the clamping assembly, which makes it easier to assemble and adjust.

[0011] As a preferred technical solution, the clamping assembly includes a front pressure plate, a rear pressure plate, pressure plate fixing screws, and lateral tightening screws. The front pressure plate and the rear pressure plate are fixedly mounted on the sliding plate by the pressure plate fixing screws. The horizontal plate is flexibly disposed in the mounting position formed between the front pressure plate and the rear pressure plate. The lateral tightening screws pass through the front pressure plate and the rear pressure plate to press or release the horizontal plate.

[0012] The advantages of the above-mentioned preferred solution are as follows: by forming an installation position between the front pressure plate and the rear pressure plate, the bracket can be installed horizontally and adjusted left and right at the same time. After adjusting the position, it can be locked. The operation is more flexible and further increases the left and right adjustment range of the bracket relative to the base.

[0013] As a preferred technical solution, one of the left support plate and the right support plate is provided with an electric drive assembly, which is drivenly connected to one end of the feed roller and the cutter shaft, respectively.

[0014] The advantages of the above-mentioned preferred solution are that the electric drive assembly automatically drives the feed roller and the cutter shaft to rotate, thereby efficiently completing the cutting operation.

[0015] As a preferred technical solution, one of the left support plate and the right support plate is provided with a first handwheel and a second handwheel. The first handwheel is driven to the other end of the feed roller, and the second handwheel is driven to the other end of the cutter shaft.

[0016] The advantages of the above preferred solution are that by setting the corresponding handwheel, manual traction can be performed when the diaphragm is just fed in, and manual unloading and sorting operations can be performed when abnormalities such as unevenness occur during diaphragm transmission.

[0017] As a preferred technical solution, a locking mechanism is provided between the sliding plate and the base plate for locking the sliding plate relative to the base plate after sliding adjustment.

[0018] The advantages of the above preferred solution are: the locking mechanism positions the sliding plate that slides left and right and is adjusted to a certain position, so that the structure is more stable and reliable during the cutting operation.

[0019] As a preferred technical solution, the locking mechanism includes a locking block, a locking block slide rail, and a locking knob. The upper end of the locking block is fixedly connected to the front side and / or rear side of the sliding plate. The locking block slide rail extends laterally and is arranged on the front side and / or rear side of the base plate. The lower end of the locking block slidably fits into the slide groove of the locking block slide rail. The locking knob has a rotating cap and a screw part connected to the rotating cap. The lower end of the locking block is provided with a screw hole for the screw part to pass through. Under control, the rotating cap drives the screw part to press against the bottom wall of the slide groove or separate from the bottom wall of the slide groove.

[0020] The advantages of the above preferred solution are that the locking mechanism not only has the function of locking the sliding plate relative to the base plate, but also provides auxiliary track support when the sliding plate slides relative to the base plate, so that the bracket is more stable and reliable when sliding and adjusting relative to the base plate.

[0021] A second aspect of this utility model provides a membrane cutting device, characterized in that it includes a right cutting edge module and a left cutting edge module arranged along the membrane transmission line. Both the right cutting edge module and the left cutting edge module adopt the membrane cutting module described above. The annular groove and annular cutter of the right cutting edge module are arranged to the right relative to the center line of the membrane transmission line, and the annular groove and annular cutter of the left cutting edge module are arranged to the left relative to the center line of the membrane transmission line.

[0022] The membrane cutting device provided by the above technical solution, by setting a right cutting module and a left cutting module, and setting the annular groove and annular cutter of the right cutting module to the right and the annular groove and annular cutter of the left cutting module to the left, can achieve simultaneous cutting of the left and right sides of the membrane in one feeding. Moreover, the cutting width of the left and right sides can be flexibly and independently adjusted. This solves the technical bottleneck in the prior art where the production of membranes with inconsistent incoming material widths requires disassembling the cutting mechanism and replacing parts to adapt to membranes of different widths each time production changes.

[0023] As a preferred technical solution, the film cutting device further includes:

[0024] The feeding module is located upstream of the right cutting module and the left cutting module, and is used to transmit the film to be cut to the right cutting module and the left cutting module;

[0025] The receiving module is located downstream of the right cutting module and the left cutting module, and is used to receive the film sheets cut by the right cutting module and the left cutting module.

[0026] The first row of waste material rollers is mounted on the bracket of the right cutting edge module and is located in front of and to the right of the annular groove and annular cutter of the right cutting edge module.

[0027] The second row of waste material rollers is mounted on the support of the left cutting edge module and is located on the left front of the annular groove and annular cutter of the left cutting edge module.

[0028] The advantages of the above-mentioned preferred solution are: by setting up a right cutting edge module and a left cutting edge module, and cooperating with a feeding module, a receiving module and a waste recycling mechanism, the efficiency of film cutting is further improved.

[0035] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", "front", "back", etc., indicating the orientation or positional relationship, are all based on the orientation or relative positional relationship shown in the accompanying drawings. They are intended to facilitate a clear description of the structure of the product or device and are not intended to limit the actual orientation of the product or device during production, use, sales, etc.

[0037] Furthermore, the terms "first" and "second" are used only for distinguishing purposes in the description and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0038] like Figure 1 As shown in the figure, as a basic embodiment, this embodiment provides a film cutting module 100, including a base plate 10, a bracket 30, a first cutter assembly 50 and a second cutter assembly 70; the first cutter assembly 50 includes a feed roller 51 and an annular groove 52 disposed at a predetermined position in the axial direction of the feed roller 51, and the second cutter assembly 70 includes a cutter shaft 71 and an annular cutter 72 disposed on the cutter shaft 71 and aligned with the annular groove 52.

[0039] The feed roller 51 and the cutter shaft 71 are mounted on the bracket 30 in parallel and rotatable configurations, forming a feed channel for the film to pass through. Thus, while the film is being fed, the annular groove 52 of the first cutter assembly 50 and the annular cutter 72 of the second cutter assembly 70 cooperate to cut the film.

[0040] Furthermore, the base plate 10 is fixedly installed, and the bracket 30 is slidably and adjustablely mounted on the base plate 10, parallel to the axial direction of the feed roller 51 (i.e., the axial direction of the cutter shaft 71). Thus, due to the diaphragm's travel path during feed (refer to...), Figure 1 (As shown by the dashed arrow) The bracket 30 is fixed relative to the base plate 10. By sliding and adjusting the position of the bracket 30 relative to the base plate 10, the cutting position of the annular groove 52 and the annular cutter 72 relative to the membrane can be adjusted, thereby trimming at least one side (left or right side) of the membrane, or cutting the membrane into sub-membranes of a predetermined width.

[0041] See also Figure 1 In a preferred embodiment, the diaphragm cutting module 100 further includes a sliding plate 20; combined with Figure 2 and Figure 3 As shown, the base plate 10 is provided with slide rails 11 distributed in a left-right direction. The sliding plate 20 is slidably mounted on the slide rails 11 via a slider 12, and the bracket 30 is fixedly mounted on the sliding plate 20. It can be understood that the sliding plate 20, slider 12, and even the slide rails 11 are not essential. The bottom of the bracket 30 can be directly mounted on the base plate 10 in a sliding manner; for example, a groove can be directly provided on the base plate 10, and a slider can be directly provided on the bottom of the bracket 30. However, the method of indirectly connecting the bracket 30 through the sliding plate 20 in conjunction with the slider 12 and the slide rails 11 simplifies the design of the bracket and base plate and facilitates processing and maintenance compared to the method where the bracket 30 slides directly on the base plate 10.

[0042] See also Figure 1 In one specific implementation, the bracket 30 includes a horizontal plate 31 and a left support plate 32 and a right support plate 33 disposed at both ends of the horizontal plate 31. The two ends of the feed roller 51 and the cutter shaft 71 are respectively rotatably disposed on the left support plate 32 and the right support plate 33.

[0043] More specifically, the left support plate 32 and the right support plate 33 can each be a segmented splicing support plate. The two ends of the feed roller 51 are rotatably mounted on the lower segment support plates of the left support plate 32 and the right support plate 33, respectively, and the two ends of the cutter shaft 71 are rotatably mounted on the upper segment support plates of the left support plate 32 and the right support plate 33, respectively. During assembly, the lower segment support plates can be first assembled on both ends of the feed roller 51 and mounted on the horizontal plate 31, and then the upper segment support plates can be assembled on both ends of the cutter shaft 71 and connected to the corresponding lower segment support plates. This allows for modular installation and maintenance.

[0044] Combination Figure 1 and Figure 2 As shown, in a preferred embodiment, the horizontal plate 31 is clamped to the sliding plate 20 by clamping components 40 provided on both the front and rear sides, which facilitates the assembly and adjustment between the bracket 30 and the sliding plate 20. Specifically, see... Figure 4 As shown, the clamping assembly 40 includes a front pressure plate 41, a rear pressure plate 42, pressure plate fixing screws, a lateral tightening screw 44, and a positioning pin 45. The front pressure plate 41 and the rear pressure plate 42 are fixedly mounted on the sliding plate 20 by the pressure plate fixing screws. The front pressure plate 41 and the rear pressure plate 42 form an installation position 401 for mounting the horizontal plate 31 of the bracket 30. The horizontal plate 31 is flexibly positioned in the installation position 401. The lateral tightening screw 44 passes through the front pressure plate and the rear pressure plate to tighten or loosen the horizontal plate 31. In this way, the horizontal plate 31 of the bracket 30 can be adjusted left and right while being installed, and then locked after being adjusted to the correct position. The operation is more flexible and further increases the left and right adjustment range of the bracket 30 relative to the base 10.

[0045] In addition, the clamping assembly 40 also includes a positioning pin 45, which is disposed on the outside of the front pressure plate 41 and the rear pressure plate 42 for positioning the front pressure plate 41 and the rear pressure plate 42 against each other.

[0046] See also Figure 1 In a preferred embodiment, an electric drive assembly 60 is provided on one of the left support plate 32 and the right support plate 33. This electric drive assembly 60 is driven and connected to one end of both the feed roller 51 and the cutter shaft 71. Specifically, the electric drive assembly 60 includes a drive motor 61 and a gearbox 62. The driving force of the drive motor 61 is transmitted and speed-changed via the gearbox 62 and then connected to one end of both the feed roller 51 and the cutter shaft 71. The electric drive assembly 60 automatically drives the feed roller 51 and the cutter shaft 71 to rotate, thereby efficiently completing the cutting operation.

[0047] See also Figure 1In a preferred embodiment, one of the left support plate 32 and the right support plate 33 is provided with a first handwheel 81 and a second handwheel 82. The first handwheel 81 is driven to the other end of the feed roller 51, and the second handwheel 82 is driven to the other end of the cutter shaft 71. By setting the corresponding handwheels, manual traction can be performed when the film is first fed, and manual unloading and sorting operations can be performed when abnormalities such as wrinkles or unevenness occur during film transmission.

[0048] See Figure 2 and Figure 3 As shown, in a preferred embodiment, a locking mechanism 90 is provided between the sliding plate 20 and the base plate 10 for locking the sliding plate 20 relative to the base plate 10 after sliding adjustment, so as to make the structure more stable and reliable during the cutting operation.

[0049] See Figure 2 and Figure 3 As shown, in one specific embodiment, the locking mechanism 90 includes a locking block 91, a locking block slide rail 92, and a locking knob 93. The upper end of the locking block 91 is fixedly connected to the front side and / or rear side of the sliding plate 20. The locking block slide rail 92 is arranged along the left and right direction on the front side and / or rear side of the base plate 10. The lower end of the locking block 91 is slidably fitted into the groove of the locking block slide rail 92. The locking knob 93 has a rotating cap and a screw part connected to the rotating cap. The lower end of the locking block 91 is provided with a screw hole for the screw part to pass through. Under control, the rotating cap drives the screw part to rotate in or out, thereby pressing against the bottom wall of the groove of the locking block slide rail 92 or separating it from the bottom wall of the groove. In this embodiment, the locking mechanism 90 not only has the function of locking the sliding plate 20 relative to the base plate 10, but also provides auxiliary track support when the sliding plate 20 slides relative to the base plate 10, so that the bracket 30 is more stable and reliable when sliding and adjusting left and right relative to the base plate.

[0050] See Figure 5 and Figure 6 As shown, a specific embodiment of the present invention also provides a membrane cutting device, including a right cutting edge module 100a and a left cutting edge module 100b arranged along the membrane transport line. Both the right cutting edge module 100a and the left cutting edge module 100b adopt the membrane cutting module 100 described above; wherein, the annular groove 52 and the annular cutter 51 of the right cutting edge module 100a are relative to the center line of the membrane transport line (reference). Figure 6 (As shown by the dashed arrow in the middle) The annular groove 52 and annular cutter 71 of the left cutting module 100b are positioned to the right relative to the center line of the membrane transmission line (see reference). Figure 6(As shown by the dashed arrow) is set to the left. This allows for simultaneous cutting of both sides of the diaphragm in a single feed; moreover, the cutting width of the left and right sides can be flexibly and independently adjusted; this solves the technical bottleneck in existing technologies where the production of diaphragms with inconsistent incoming material widths requires disassembling the cutting mechanism and replacing parts to adapt to different diaphragm widths with each production change.

[0051] In a preferred embodiment, the membrane cutting device described above further includes:

[0052] The feeding module (not shown in the figure) is located upstream of the right cutting module 100a and the left cutting module 100b, and is used to transmit the film to be cut to the right cutting module 100a and the left cutting module 100b.

[0053] The receiving module (not shown in the figure) is located downstream of the right cutting module 100a and the left cutting module 100b, and is used to receive the film sheets cut by the right cutting module 100a and the left cutting module 100b.

[0054] The first row of waste material rollers 200 is mounted on the bracket 30 of the right cutting edge module 100a and is located in front of the right side of the annular groove 52 and the annular cutter 72 of the right cutting edge module 100a.

[0055] The second row of waste material rollers 300 is mounted on the bracket 30 of the left cutting module 100b and is located on the left front of the annular groove 52 and the annular cutter 72 of the left cutting module 100b.

[0056] The first row of waste rollers 200 and the second row of waste rollers 300 are driven by air blowing or motor drive, so that the rotation direction of the rollers is consistent with the rotation direction of the cutter, avoiding the accumulation of waste and causing abnormal operation of the mechanism, and allowing the waste to fall into the waste collection point as needed.

[0057] The above preferred embodiment further improves the film cutting efficiency by setting up a right cutting edge module 100a and a left cutting edge module 100b, and cooperating with a feeding module, a receiving module and a waste recycling mechanism.

[0058] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application are still within the scope of this application. Furthermore, it is understood that the film cutting module device provided by the present invention is not only suitable for cutting films (film materials), but also for thin sheet materials such as cardboard, kraft paper, and carbon fiber woven materials.
