Description

Technical Field

[0001] This application relates to the technical field of coating doctor blade cutting equipment, and in particular to a diaphragm coating doctor blade cutting device with length and quantity measuring functions. Background Technology

[0002] The separator coating doctor blade is a core consumable in the production of lithium battery separator coating. Its cutting quality directly affects the coating effect and product yield. The separator coating doctor blade cutting device is a special equipment used to cut the doctor blade to a fixed length according to the coating width. Its performance determines the flatness of the doctor blade cut, dimensional accuracy and production efficiency.

[0003] Currently, there are relevant studies in the existing technology, such as the cutting device for producing cleaning scrapers disclosed in the authorization announcement number CN220972480U, which includes a main body, a conveying channel at one end of the main body, and an inner groove inside the other end, with the bottom of the inner groove being set as an inclined surface; a cutting blade is provided at the top of the inner groove, and the cutting blade is driven to move up and down by a second hydraulic rod on a fixed frame to achieve cutting; a movable baffle is provided inside the inner groove, and the position of the baffle is adjusted to adapt to the cutting needs of scrapers of different lengths; in terms of conveying, the material is automatically conveyed by a roller driven by a motor, and the material is fixed by a pressure plate driven by a third hydraulic rod.

[0004] The defects of the above-mentioned patented technology are as follows: First, it lacks effective guidance and clamping constraints for the scraper during the conveying process. When the material is thin or soft, it is easy to deviate, curl, or curl upwards, affecting the cutting accuracy. Second, it only relies on the baffle for mechanical positioning and does not have a real-time measurement function for the cutting length. After the cutting is completed, it cannot automatically record the total length and number of scrapers that have been cut. It still requires manual measurement and ledger recording, which poses a risk of omission and misrecording, and is difficult to meet the needs of accurate management of material consumption in mass production. Summary of the Invention

[0005] The purpose of this application is to provide a diaphragm coating scraper cutting device with length and quantity measurement functions to solve the problems in the prior art.

[0006] The diaphragm coating scraper cutting device provided in this application adopts the following technical solution: it includes a base platform and a sliding cutting mechanism. A length scale is horizontally installed on the front side of the upper end of the base platform. A scraper box clamp for adjustable clamping of the scraper box is installed on the left side of the upper end of the base platform. A scraper guide block is fixed on the upper right side of the scraper box clamp. A placement guide groove frame is installed in the middle of the upper end of the base platform. The sliding cutting mechanism is slidably connected to the upper right side of the base platform. An intelligent control box is provided on the right side of the base platform. It also includes a feeding conveyor device installed on the outside of the placement guide groove frame.

[0007] By adopting the above technical solution, a comprehensive platform integrating rapid blade positioning, manual or automatic sliding cutting, and real-time length / quantity measurement is constructed. A length ruler is used for rough reference, while a rotary encoder on the sliding cutting mechanism accurately measures the actual cutting stroke. Hall sensors record the number of cuts, and the intelligent control box has a built-in microcontroller that can trigger a buzzer when the user-preset cutting length is reached, and automatically accumulate the total meters and total number of pieces. It also supports saving data after power failure, solving the problems of large errors in manual measurement and easy omissions in the ledger.

[0008] Preferably, the feeding and conveying device includes a drive motor, which is installed inside the left side of the base platform, and the output end of the drive motor is connected to a screw. The screw is installed inside the base platform in a horizontal rotation, and the outside of the screw is threadedly connected to the upper end of the side clamping assembly. The upper side of the side clamping assembly is provided with a pressing component, and the side of the side clamping assembly is connected to a rear pressing component.

[0009] By adopting the above technical solution, the screw is driven to rotate by a drive motor, and the rotational power is converted into linear feed motion of the side clamping assembly along the base platform by using thread transmission. During this process, the side clamping assembly simultaneously drives the lowering assembly and the rear pressing assembly to achieve multiple coordinated actions of lateral clamping of the diaphragm coating doctor blade, pressing down at the feed end, and pressing at the tail end, ensuring that the material always maintains a straight and stable posture during the conveying process, providing a basic guarantee for subsequent precise cutting.

[0010] Preferably, the side clamp assembly includes a bracket, which slides against the upper end of the base platform, and the bottom of the bracket is threadedly connected to a screw. A transmission plate is slidably installed inside the upper end of the bracket. Cylinders are connected to both sides of the bottom of the transmission plate, and the cylinders on both sides are connected to the inner side of the bracket. Transmission grooves are opened on both sides of the upper end of the transmission plate. The inside of the transmission groove is slidably connected to the bottom shaft of the slide bar, and the slide bar is slidably connected to the guide rod externally. The guide rod is inserted into both sides of the upper end of the bracket. A connecting seat is bolted to the upper end of the slide bar. A push-pull rod is inserted into the upper end of the connecting seat. The push-pull rod extends through into the side of the guide groove frame, and the through end of the push-pull rod is connected to a side plate.

[0011] By adopting the above technical solution, the transmission plate is driven by a cylinder to move left and right within the bracket. The horizontal movement is converted into the linear sliding of the slide bar along the guide rod by the sliding engagement of the transmission grooves on both sides of the upper end of the transmission plate with the bottom shaft of the slide bar. The slide bar then drives the push-pull rod and side plate to move through the connecting seat, realizing the rapid lateral clamping or loosening of the material inside the guide groove frame. The guide rod ensures the straightness and stability of the slide bar's movement. In this way, combined with the lateral clamping effect, the automatic clamping, conveying, feeding, and cutting preparation of the diaphragm coating doctor blade can be realized with the drive of the drive motor and screw.

[0012] Preferably, the pressing assembly includes a support, which is locked to the outside of one side of the guide rod, and a pressure arm is rotatably connected to the upper end of the support. A rubber pad is installed at the bottom of the pressure arm, and a connecting piece is locked to the outside of the support. An elastic shaft is inserted into one side of the connecting piece. The bottom of the elastic shaft is rotatably connected to the pressure arm, and the top of the elastic shaft is fixedly connected to the crossbar. Both sides of the crossbar are inserted into the pressure groove, and the pressure groove is opened inside the movable piece. The movable piece is fixed to the top of the side plate.

[0013] By adopting the above technical solution, when the two side plates are laterally clamped and moved, the moving piece fixed to the top of the side plate moves synchronously. The pressure groove inside the moving piece pushes the crossbar down through the inclined surface. The crossbar moves down, causing the elastic shaft to squeeze the pressure arm and lift the rubber pad at the bottom of the pressure arm to smoothly press the feed end of the diaphragm coating scraper. Thus, while achieving lateral clamping, the feed end is automatically pressed and fixed, which enhances the stability of subsequent scraper feeding and conveying and avoids the problem of insufficient clamping force.

[0014] Preferably, the rear pressure assembly includes a sliding seat, which is slidably mounted on both ends of one side of the guide slot frame. A lifting groove is provided inside the sliding seats on both sides. A series plate is connected to the top of each sliding seat on both sides. A vertical rod is inserted into the upper end of each series plate. The upper end of each vertical rod is vertically inserted into the guide slot frame. A return spring is provided outside the vertical rod. The lower and upper ends of the return spring are respectively connected to the series plate and the guide slot frame. A pressure roller is rotatably mounted on the top of the vertical rod. A transmission wheel is embedded inside the lifting groove. The transmission wheel is rotatably mounted on the upper end of a fixing strip, and the fixing strip is fixed to the side of the bracket.

[0015] By adopting the above technical solution, when the support moves under the drive of the screw, the fixing strip fixed to the side of the support drives the transmission wheel to move synchronously. When the transmission wheel moves out of the lifting groove inside the sliding seat, it will release the lifting effect, so that the upright, in conjunction with the return spring in the external compressed state, will move automatically downward. In this way, the upright drives the pressure roller connected to the top to press and place the diaphragm coating scraper entering the feed end of the guide groove frame. If the fixing strip drives the transmission wheel to move into the lifting groove, the upright will be lifted synchronously, releasing the pressure roller on the diaphragm coating scraper, ensuring that the subsequent feeding of the diaphragm coating scraper is not obstructed, and effectively preventing the material from warping or sliding at the tail during the conveying process.

[0016] Preferably, the sliding cutting mechanism includes a sliding blade holder, which is slidably connected to the outer side of the upper end of the base platform. A cutting blade body is installed inside the sliding blade holder, and a magnet is provided at the outer gripping end of the cutting blade body. A Hall sensor is provided on the front side of the upper end of the sliding blade holder. A buzzer is locked in the middle of the left side of the sliding blade holder, and a rotary encoder is locked in the lower left side of the sliding blade holder. The rotary encoder rotates to contact the counting end, which abuts against the groove inside the guide slot.

[0017] By adopting the above technical solution, when the operator pushes the sliding blade holder along the base platform, the measuring roller of the rotary encoder rolls against the surface of the scraper, converting the number of rotations into the distance traveled in real time, thereby accurately measuring the cutting length. At the same time, the Hall sensor works with the magnet on the cutter body. When the cutter body completes a cut and is pushed back to the starting point, the Hall sensor senses the magnet and outputs a pulse signal, automatically incrementing the cut count by 1. The intelligent control box has a built-in microcontroller that receives the encoder and Hall signals and automatically completes activities such as total meter and total piece count, solving the problem of errors and omissions in manual ledgers.

[0018] Preferably, both sides of the transmission plate are slidably connected to the inner limit of the upper end of the bracket, and the transmission grooves on both sides of the upper end of the transmission plate are opened in opposite inclined directions.

[0019] By adopting the above technical solution, namely, the transmission grooves on both sides of the transmission plate adopt opposite inclination directions, when the transmission plate moves left and right under the drive of the cylinder, the slide bars on both sides will move in opposite directions or in opposite directions along the guide rod, thereby driving the side plates on both sides to clamp or release the material synchronously and symmetrically, ensuring that the material is always centered and aligned, avoiding material deviation due to uneven force on one side, and significantly improving the concentricity of clamping, the accuracy of cutting position, and the stability of clamping, conveying and feeding process.

[0020] Preferably, the connecting seat, push-pull rod and side plate are symmetrically arranged between the guide rods on both sides, and the dimensions of the side plate match the dimensions of the internal groove of the guide slot frame.

[0021] By adopting the above technical solution, the connecting seat, push-pull rod, and side plate are symmetrically arranged between the two guide rods, ensuring that the force at both ends of the push-pull rod is completely balanced. The side plate can fit against both sides of the scraper to be fed and conveyed in a parallel and uniform surface contact manner, avoiding material bending caused by unilateral gaps or pressure differences. At the same time, the size of the side plate is precisely matched with the size of the internal groove of the guide trough frame, which not only ensures the tightness of the clamping, but also provides a precise straight guide channel for the material.

[0022] Preferably, both sides of the crossbar are inclined, and the mating grooves on both sides of the crossbar are opened with opposite inclined surfaces.

[0023] By adopting the above technical solution, in which the inclined surfaces on both sides of the crossbar cooperate with the opposite inclined surfaces of the pressure groove, when the moving piece moves with the side plate, the horizontal linear motion is precisely and smoothly converted into the vertical lifting motion of the crossbar through the wedge action of the inclined surfaces. This double inclined surface cooperation method effectively increases the contact area, avoids stress concentration, and ensures the smoothness and gentleness of the pressing action. At the same time, it can linearly control the pressing force according to the moving stroke of the side plate, so that the pressing force of the rubber pad on the material is automatically adjusted synchronously with the clamping action.

[0024] Preferably, the rear pressure assembly is installed at the feeding end of the placement guide groove frame, and the pressure roller installed inside the rear pressure assembly is vertically opposite to the groove opened inside the placement guide groove frame.

[0025] By adopting the above technical solution, the rear pressure component is set at the feeding end of the guide slot frame, and the pressure roller corresponds vertically to the slot body. This allows the diaphragm coating doctor blade to be laterally clamped and pressed down by the lower pressure component and the rear pressure component. During automatic feeding, the pressure roller automatically descends to assist in pressing the diaphragm coating doctor blade entering the guide slot frame. This effectively prevents the diaphragm coating doctor blade from curling, folding, or tilting upwards due to gravity or conveying inertia in the early stage of feeding. It ensures that the diaphragm coating doctor blade can enter the subsequent clamping and cutting stations smoothly and evenly, greatly improving the reliability of feeding and the yield rate.

[0026] Preferably, the lifting groove is inclinedly opened at the lower end of the sliding seat, and limiting grooves are extended on both sides inside the lifting groove.

[0027] By adopting the above technical solution, namely, the lifting groove adopts an inclined opening structure, the horizontal rolling driving force of the transmission wheel can be efficiently converted into the vertical lifting driving force of the sliding seat; at the same time, the limiting grooves extending on both sides inside the lifting groove limit and constrain the axial movement of the transmission wheel, preventing the transmission wheel from lateral deviation or derailment during rolling, ensuring the accuracy of the lifting stroke of the sliding seat and the safety of operation, so that the lifting action of the rear pressure component is always smooth, reliable and without jamming.

[0028] In summary, this application includes the following beneficial technical effects: 1. This application achieves real-time high-precision measurement of cutting length by setting up a sliding cutting mechanism, in which the roller of the rotary encoder is pressed against the scraper surface and rolls when the sliding blade holder moves, accurately converting the number of rotations into the moving distance; at the same time, the Hall sensor and magnet work together to output a pulse signal to automatically accumulate the number of cut pieces when the cutter body is reset; the built-in microcontroller in the intelligent control box completes the automatic accumulation and display of data, and supports power-off data saving, solving the problems of large errors in manual measurement and easy omissions in the ledger, and significantly improving the intelligent management level of cutting operations.

[0029] 2. This application achieves automatic clamping, pulling out, and flattening of the scraper by setting up a feeding conveyor device, that is, the drive motor drives the screw to rotate, and the side clamping assembly moves linearly from left to right along the placement guide slot frame through the thread transmission. This completely replaces the traditional manual operation of pulling the scraper, which not only greatly reduces the labor intensity of the operators, but also ensures the consistency of the feeding length each time, providing a stable and reliable material foundation for subsequent precise cutting.

[0030] 3. This application sets up a side clamping assembly, in which a cylinder drives the transmission plate to move within the bracket. By means of the sliding cooperation between the transmission groove and the bottom shaft of the slide bar, the horizontal movement is smoothly converted into the synchronous linear sliding of the two slide bars. Then, through the connecting seat and the push-pull rod, the two side plates are symmetrically clamped to clamp the scraper, ensuring that the scraper is always centered and aligned and subjected to uniform force. This effectively avoids material deviation or tilting caused by unilateral clamping and greatly improves the repeatability of the cutting position.

[0031] 4. This application sets up a downward pressing component, that is, when the side plate clamps and moves, the moving piece fixed to its top moves synchronously. The pressure groove inside the moving piece pushes the crossbar down through the inclined surface. The crossbar transmits the downward pressure to the pressure arm through the elastic shaft, so that the rubber pad at the bottom of the pressure arm applies a uniform and controllable clamping force to the scraper feed end. This realizes the mechanical linkage between lateral clamping and feed end pressing, without the need for an additional power source. It effectively prevents the scraper feed end from tilting up during the conveying process, and enhances the stability and reliability of the feeding.

[0032] 5. This application incorporates a rear-pressure component. When the bracket moves to the right, the fixing strip on its side drives the transmission wheel to move out of the lifting groove inside the sliding seat. After the lifting effect is released, the compressed return spring releases its elasticity, pushing the series plate and the sliding seat downward as a whole. This causes the pressure roller at the top of the upright to automatically press against the upper surface of the scraper tail. Combined with the lateral clamping of the side plate, this forms a double constraint on both ends of the scraper, effectively preventing the scraper tail from tilting or sliding due to gravity or inertia during transport. This ensures that the scraper always maintains a flat and unfolded posture within the guide slot frame, laying a good foundation for subsequent precise cutting. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 11 This application will be described in further detail below.

[0036] A diaphragm coating scraper cutting device with length and quantity measuring functions, as shown in the reference. Figures 1-3 The system includes a base platform 1 and a sliding cutting mechanism. A length scale 2 is horizontally mounted on the front side of the upper end of the base platform 1. A scraper box clamp 3 for adjustable clamping of the scraper box is installed on the left side of the upper end of the base platform 1. A scraper guide block 4 is fixed on the upper right side of the scraper box clamp 3. A guide opening is integrally opened in the middle of the scraper guide block 4 for positioning and guiding the scraper. A guide groove frame 5 is installed in the middle of the upper end of the base platform 1. A sliding cutting mechanism is slidably connected to the upper right side of the base platform 1. An intelligent control box 12 is provided on the right side of the base platform 1. The system also includes a feeding conveyor device 13 installed on the outside of the guide groove frame 5. The sliding cutting mechanism includes a sliding blade holder 6, which is slidably connected to the outer side of the upper end of the base platform 1. A cutting blade body 7 is installed inside the sliding blade holder 6, and a magnet 8 is provided at the outer gripping end of the cutting blade body 7. A Hall sensor 9 is provided on the front side of the upper end of the sliding blade holder 6. A buzzer 10 is locked in the middle of the left side of the sliding blade holder 6, and a rotary encoder 11 is locked in the lower left side of the sliding blade holder 6. The rotary encoder 11 rotates and contacts the counting end, which abuts against the inner groove of the guide slot 5.

[0037] The sliding cutting mechanism includes a sliding blade holder 6, which is slidably connected to the outer side of the upper end of the base platform 1. A cutting blade body 7 is installed inside the sliding blade holder 6, and a magnet 8 is provided at the outer gripping end of the cutting blade body 7. A Hall sensor 9 is provided on the front side of the upper end of the sliding blade holder 6. A buzzer 10 is locked in the middle of the left side of the sliding blade holder 6, and a rotary encoder 11 is locked in the lower left side of the sliding blade holder 6. The rotary encoder 11 rotates and contacts the counting end, which abuts against the inner groove of the guide slot 5.

[0038] Furthermore, when the operator pushes the sliding blade holder 6 along the base platform 1, the measuring roller of the rotary encoder 11 rolls against the scraper surface, converting the number of rotations into the distance traveled in real time, thereby accurately measuring the cutting length. Simultaneously, the Hall sensor 9 works in conjunction with the magnet 8 on the cutter body 7. Each time the cutter body 7 completes a cut and returns to the starting point, the Hall sensor 9 senses the magnet 8 and outputs a pulse signal, automatically incrementing the cut count by 1. The intelligent control box 12, with its built-in microcontroller, receives the encoder and Hall signals and automatically performs the following: displaying the cutting length and adding it to the total length register; incrementing the cut count; allowing the user to set a target length, which is then indicated by a buzzer 10. In addition, the intelligent control box 12 also has a data storage module, which can save the total meters and total cut count even after a power outage, solving the problem of errors and omissions in manual record keeping.

[0039] Reference Figures 4-6 The feeding conveying device 13 includes a drive motor 131, which is installed inside the left side of the base platform 1. The output end of the drive motor 131 is connected to a screw 132. The screw 132 is installed inside the base platform 1 and rotates laterally. The outside of the screw 132 is threadedly connected to the upper end of the side clamping assembly 133. That is, when the drive motor 131 and the screw 132 drive, the side clamping assembly 133 will move laterally from left to right along the outside of the placement guide slot frame 5. The upper right side of the side clamping assembly 133 is provided with a pressing assembly 134, and the left side of the side clamping assembly 133 is connected to a rear pressing assembly 135. The rear pressing assembly 135 is installed at the scraper feeding support end of the placement guide slot frame 5.

[0040] Furthermore, the drive motor 131 drives the screw 132 to rotate, and the rotational power is converted into linear feed motion of the side clamping assembly 133 along the base platform 1 through the threaded transmission. During this process, the side clamping assembly 133 simultaneously drives the pressing assembly 134 and the rear pressing assembly 135 to achieve multiple coordinated actions of lateral clamping of the diaphragm coating doctor blade, pressing down at the feed end, and pressing at the tail end, ensuring that the material always maintains a straight and stable posture during the conveying process, providing a basic guarantee for subsequent precise cutting.

[0041] Reference Figures 7-8The side clamping assembly 133 includes a bracket 1331, which slides against the upper end of the base platform 1. The bottom of the bracket 1331 is threadedly connected to the screw 132. A transmission plate 1332 is laterally slidably mounted inside the upper end of the bracket 1331. Cylinders 1333 are connected to the front and rear ends of the bottom left side of the transmission plate 1332. The two cylinders 1333 are connected to the inner side of the bracket 1331. That is, when the two cylinders 1333 push and pull the transmission plate 1332, the transmission plate 1332 will slide left and right along the inner side of the upper end of the bracket 1331. Transmission grooves 1 are opened on the front and rear sides of the upper end of the transmission plate 1332. 334, the transmission grooves on both sides 1334 are slidably connected to the bottom shafts of the slide bars 1335 on both sides, and the slide bars 1335 on both sides are slidably connected to the front and rear external limiters of the guide rods 1336 on both sides. The guide rods 1336 on both sides are longitudinally inserted into the left and right sides of the upper end of the bracket 1331 to achieve guiding cooperation. The upper end of the slide bars 1335 on both sides is bolted to the connecting seat 1337. The upper end of the connecting seat 1337 on both sides is longitudinally inserted with the push-pull rod 1338. The push-pull rods 1338 on both sides extend longitudinally through into the front and rear sides of the guide groove frame 5, and the through end of the push-pull rods 1338 on both sides is connected to the side plate 1339.

[0042] Furthermore, the transmission plate 1332 is driven by the cylinder 1333 to move left and right within the bracket 1331. The horizontal movement is converted into the linear sliding of the slide bar 1335 along the guide rod 1336 by the sliding engagement of the transmission grooves 1334 on both sides of the upper end of the transmission plate 1332 with the bottom shaft of the slide bar 1335. The slide bar 1335 then drives the push-pull rod 1338 and the side plate 1339 to move through the connecting seat 1337, realizing the rapid lateral clamping or loosening of the material inside the guide slot frame 5. The guide rod 1336 ensures the straightness and stability of the slide bar movement. In this way, combined with the lateral clamping effect, the automatic clamping, conveying, feeding and cutting preparation of the diaphragm coating scraper can be realized with the drive of the drive motor 131 and the screw 132.

[0043] The transmission plate 1332 has both sides that are internally limited and slidably connected to the upper sides of the bracket 1331, and the transmission grooves 1334 on both sides of the upper end of the transmission plate 1332 are opened in opposite inclined directions.

[0044] Furthermore, the transmission grooves 1334 on both sides of the transmission plate 1332 adopt opposite inclination directions. When the transmission plate 1332 moves left and right under the drive of the cylinder 1333, the slide bars 1335 on both sides will move in opposite directions or in opposite directions along the guide rod 1336, thereby driving the side plates 1339 on both sides to clamp or release the material synchronously and symmetrically, ensuring that the material is always centered and aligned, avoiding material deviation due to uneven force on one side, significantly improving the concentricity of clamping, the accuracy of cutting position, and the stability of clamping, conveying and feeding process.

[0045] Among them, the connecting seat 1337, the push-pull rod 1338 and the side plate 1339 are symmetrically arranged between the two guide rods 1336, and the size of the side plate 1339 matches the size of the internal groove of the guide groove frame 5.

[0046] Furthermore, the connecting seat 1337, push-pull rod 1338, and side plate 1339 are symmetrically arranged between the two guide rods 1336, ensuring that the force on both ends of the push-pull rod 1338 is completely balanced, and the side plate 1339 can fit against both sides of the scraper to be fed and conveyed in a parallel and uniform surface contact manner, avoiding material bending caused by unilateral gaps or pressure differences; at the same time, the size of the side plate 1339 is precisely matched with the size of the internal groove of the guide groove frame 5, which not only ensures the tightness of the clamping, but also provides a precise straight guide channel for the material.

[0047] Reference Figure 9 The pressing assembly 134 includes a support 1341, which is locked to the outer end of the middle of the right guide rod 1336. A pressure arm 1342 is rotatably connected to the upper end of the support 1341, and the pressure arm 1342 is arranged laterally to the left, facing the feed end of the diaphragm coating doctor blade. Three rubber pads 1343 are installed at the bottom of the pressure arm 1342 to improve the clamping firmness with the feed end of the diaphragm coating doctor blade. A connecting piece 1344 in the shape of an inverted L is locked to the outside of the support 1341. An elastic shaft 134 is movably inserted into the left side of the connecting piece 1344. 5. The elastic shaft 1345 is consistent with the existing elastic rod structure, that is, it is elastically pressed together by an internal spring. The bottom of the elastic shaft 1345 is rotatably connected to the pressure arm 1342, and the top of the elastic shaft 1345 is fixedly connected to the crossbar 1346. The elastic shaft 1345 and the crossbar 1346 form a T-shaped strip. The front and rear sides of the crossbar 1346 are inserted into the pressure groove 1347, and the pressure groove 1347 is respectively opened in the front and rear moving pieces 1348. The moving pieces 1348 are fixed to the top of the front and rear side plates 1339 and move synchronously with them.

[0048] Furthermore, when the two side plates 1339 move laterally, the movable piece 1348 fixed to the top of the side plate 1339 moves synchronously. The pressure groove 1347 inside the movable piece 1348 pushes the crossbar 1346 down through the inclined plane. The crossbar 1346 moves down, causing the elastic shaft 1345 to squeeze the pressure arm 1342, lifting the rubber pad 1343 at the bottom of the pressure arm 1342 to smoothly press the feed end of the diaphragm coating scraper. Thus, while achieving lateral clamping, the feed end is automatically pressed down and fixed, which enhances the stability of subsequent scraper feeding and conveying and avoids the problem of insufficient clamping force.

[0049] The horizontal bar 1346 has inclined surfaces on both sides, and the pressing grooves 1347 that meet on both sides of the horizontal bar 1346 have opposite inclined surfaces.

[0050] Furthermore, the inclined surfaces on both sides of the horizontal bar 1346 cooperate with the opposite inclined surfaces of the pressure groove 1347. When the moving piece 1348 moves with the side plate 1339, the horizontal linear motion is precisely and smoothly converted into the vertical lifting motion of the horizontal bar 1346 through the wedge action of the inclined surfaces. This double inclined surface cooperation effectively increases the contact area, avoids stress concentration, and ensures the smoothness and gentleness of the pressing action. At the same time, it can linearly control the pressing force according to the moving stroke of the side plate, so that the pressing force of the rubber pad 1343 on the material is automatically adjusted synchronously with the clamping action.

[0051] Reference Figures 10-11 The rear pressure assembly 135 includes a sliding seat 1351, which is slidably mounted on both sides of the lower left end of the guide slot frame 5. That is, the two sliding seats 1351 can slide up and down along the lower left side of the guide slot frame 5. Each of the two sliding seats 1351 has a lifting groove 1352 inside. A connecting plate 1353 is connected to the top of each of the two sliding seats 1351. Vertical rods 1354 are vertically inserted into the front and rear sides of the upper end of the connecting plate 1353. The vertical rods 1354 on both sides... Both ends are vertically inserted into the guide slot frame 5, and the two side uprights 1354 are provided with return springs 1355. The lower and upper ends of the two side return springs 1355 are respectively connected to the series plate 1353 and the guide slot frame 5. The top of the upright 1354 is rotatably equipped with a pressure roller 1356. The lifting slot 1352 is embedded with a transmission wheel 1357. The transmission wheel 1357 is rotatably mounted on the upper end of the fixing strip 1358, and the fixing strip 1358 is fixed to the side of the bracket 1331.

[0052] Furthermore, when the bracket 1331 moves under the drive of the screw 132, the fixing strip 1358 fixed to the side of the bracket 1331 drives the transmission wheel 1357 to move synchronously. That is, when the transmission wheel 1357 moves out of the lifting groove 1352 inside the sliding seat 1351, it will release the lifting effect, so that the upright 1354, in conjunction with the return spring 1355 in the external compressed state, will move automatically downward. In this way, the upright 1354 drives the pressure roller 1356 connected at the top to press the diaphragm coating scraper that enters the feed end of the guide slot frame 5. If the fixing strip 1358 drives the transmission wheel 1357 to move into the lifting groove 1352, the upright 1354 will be lifted synchronously, releasing the pressure roller 1356 from pressing the diaphragm coating scraper, ensuring that the subsequent feeding of the diaphragm coating scraper is not obstructed, and effectively preventing the material from warping or sliding at the tail during the conveying process.

[0053] The rear pressure assembly 135 is installed at the feeding end of the guide slot frame 5, and the pressure roller 1356 installed inside the rear pressure assembly 135 is vertically opposite to the slot opened inside the guide slot frame 5.

[0054] Furthermore, the rear pressure component 135 is positioned at the feed end of the guide slot frame 5, and the pressure roller 1356 corresponds vertically to the slot body. This allows the diaphragm coating doctor blade to be laterally clamped and pressed down by the lower pressure component 134 and the rear pressure component 135. During automatic feeding, the pressure roller 1356 automatically descends to assist in pressing the diaphragm coating doctor blade entering the guide slot frame 5. This effectively prevents the diaphragm coating doctor blade from curling, folding, or tilting upwards due to gravity or conveying inertia in the early stages of feeding. This ensures that the diaphragm coating doctor blade can smoothly and evenly enter the subsequent clamping and cutting stations, significantly improving the reliability and yield of feeding.

[0055] The lifting groove 1352 is inclinedly opened at the lower end of the sliding seat 1351, and the lifting groove 1352 is extended to both sides of the interior to form limiting grooves.

[0056] Furthermore, the lifting groove 1352 adopts an inclined opening structure, which can efficiently convert the horizontal rolling driving force of the transmission wheel 1357 into the vertical lifting driving force of the sliding seat 1351. At the same time, the limiting grooves extending on both sides inside the lifting groove 1352 limit and constrain the axial movement of the transmission wheel 1357, preventing the transmission wheel 1357 from laterally deviating or derailing during rolling, ensuring the accuracy of the lifting stroke of the sliding seat 1351 and the safety of operation, so that the lifting action of the rear pressure assembly 135 is always smooth, reliable and without jamming.

[0057] The working principle of this application is as follows: First, in the initial positioning stage, the operator installs the scraper box in the scraper box clamp 3 on the upper end of the base platform 1, and adjusts the scraper box clamp 3 to firmly clamp the scraper box to accommodate scrapers of different widths. After the scraper is pulled out of the scraper box, it is guided by the guide opening in the middle of the scraper guide block 4 fixed on the upper right side of the scraper box clamp 3, so that the scraper is accurately aligned and enters the feed end slot on the left side of the guide slot frame 5. At the same time, the base platform 1 serves as the supporting foundation of the entire device, and the length scale 2 installed horizontally at the front end of it allows the operator to visually refer to the scraper extension length, realize the initial length reference, and provide assistance for subsequent precise cutting. The scraper is conveyed to the right along the inner slot of the guide slot frame 5 and enters the subsequent clamping and pressing station. Secondly, during the clamping and conveying stage, the feeding conveyor 13 is started, and the drive motor 131 drives the screw 132 to rotate. Through the threaded transmission, the side clamping assembly 133 moves linearly from left to right along the base platform 1. Before the side clamping assembly 133 moves, the cylinder 1333 inside it first drives the transmission plate 1332 to move to the right within the bracket 1331. By utilizing the transmission grooves 1334 opened in opposite inclined directions on both sides of the upper end of the transmission plate 1332 and the sliding engagement with the bottom shaft of the slide bar 1335, the horizontal movement of the transmission plate 1332 is converted into the linear sliding of the two slide bars 1335 along the guide rod 1336 in opposite or opposite directions. In this way, the slide bars 1335 drive the push-pull rod 1338 and the side plate 1339 to move synchronously and symmetrically through the connecting seat 1337, realizing the rapid clamping of the front and rear sides of the scraper inside the guide slot frame 5. While the side plate 1339 clamps the scraper, the movable piece 1348 fixed to the top of the side plate 1339 moves synchronously with the side plate. The pressure groove 1347 inside the movable piece 1348 pushes the horizontal bar 1346 down through the inclined plane. The horizontal bar 1346 further squeezes the pressure arm 1342 through the elastic shaft 1345, so that the downward pressure of the rubber pad 1343 at the bottom of the pressure arm 1342 on the scraper feed end is increased from the pre-pressure to the working clamping force, realizing the synchronous linkage of lateral clamping and feed end downward pressure. After that, the drive motor 131 and the screw 132 continue to drive the side clamping assembly 133 to move to the right, clamping and pulling the scraper to unfold flat along the groove at the upper end of the guide groove frame 5. After the scraper is fully unfolded to the preset cutting position, the side clamping assembly 133 stops moving and maintains the clamping state, preparing for subsequent precise cutting. As the side clamp assembly 133 moves to the right, the fixing strip 1358 fixed to the side of the bracket 1331 drives the transmission wheel 1357 to move synchronously. When the transmission wheel 1357 gradually moves out of the lifting groove 1352 opened inside the sliding seat 1351, the lifting effect is released. At this time, the return spring 1355, which is in a compressed state, releases its return force, pushing the series plate 1353 and the sliding seat 1351 to move down as a whole, thereby driving the upright 1354 and the pressure roller 1356 to automatically descend, so that the pressure roller 135... 6. Press the upper surface of the scraper tail and, together with the lateral clamping of the side plate 1339, effectively prevent the scraper tail from tilting or sliding during the conveying process, ensuring that the scraper always maintains a straight posture within the guide slot frame 5. When the fixing bar 1358 moves to the left and resets with the bracket 1331, it will drive the transmission wheel 1357 to move into the lifting slot 1352. Then, the horizontal thrust is converted into the vertical lifting force of the sliding seat 1351 through the inclined surface, releasing the pressing effect of the pressure wheel 1356 and ensuring that the subsequent scraper feeding is not obstructed. Next, in the cutting and measurement stage, after the scraper is fully extended and held in position, the operator presets the target cutting length on the intelligent control box 12, and then manually pushes the sliding blade holder 6 to slide from left to right along the base platform 1. The cutter body 7 installed inside the sliding blade holder 6 can cut the scraper. During the movement of the sliding blade holder 6, the rotary encoder 11 installed on the lower left side of the sliding blade holder 6 rolls against the scraper surface through its measuring roller, converting the number of roller rotations into the moving distance in real time, and accurately measuring the cutting length. At the same time, the operator can preset the target cutting length on the intelligent control box 12. When the actual moving distance reaches the preset value, the built-in microcontroller of the intelligent control box 12 issues a command to trigger the buzzer 10 to emit a prompt sound, reminding the operator that the cutting is in place. Finally, during the reset counting phase, when the operator holds the cutting blade body 7 to perform cutting activities, each time the cutting blade body 7 completes a full cut and returns to the starting point, when the magnet 8 approaches the Hall sensor 9 on the front side of the upper end of the sliding blade holder 6, the Hall sensor 9 senses the magnet signal and outputs a pulse signal to the intelligent control box 12. After receiving the signal, the microcontroller automatically performs the following operations: adding the current cutting length to the total length register, automatically incrementing the number of cut pieces by 1, and simultaneously displaying the current cutting length and the current cumulative data on the display screen of the intelligent control box 12. If the cutting blade body 7 does not return to the starting point before the next cut, the Hall sensor 9 will not output a new pulse, and the piece counter will not count repeatedly, thus preventing errors. In addition, the intelligent control box 12 also has a data storage module inside, which can still save the cumulative total meters and total number of pieces after power failure, completely solving the problem of easy errors and omissions in manual ledger recording.

[0058] This application provides a diaphragm coating scraper cutting device with length and quantity measurement functions. It includes a base platform 1, a sliding cutting mechanism, and a feeding conveyor 13. The scraper is positioned by the scraper box clamp 3 and the scraper guide block 4 before entering the placement guide slot 5. A drive motor 131 and a screw 132 drive the side clamping assembly 133 of the feeding conveyor 13 to move from left to right. This, in conjunction with the pressing assembly 134 and the rear pressing assembly 135, achieves lateral clamping of the scraper, pressing down on the feeding end, and tightening at the tail, automatically pulling out and flattening the scraper. Subsequently, in conjunction with the sliding cutting mechanism and the intelligent control box 12, it automatically completes the total meter and total piece counting activities. After cutting, the data is automatically accumulated and displayed on the intelligent control box 12, supporting power-off data saving. This application features automatic measurement of cutting length and quantity, automatic data accumulation to prevent errors, stable feeding clamping, and high cutting accuracy.
