Description

Technical Field

[0001] The invention relates to the technical field of quick assembly and disassembly, and in particular to a micro-concave coating head glue tank based on a quick assembly and disassembly structure. Background Art

[0002] Dimple coating heads are precision components commonly used in coating processes, widely used in lithium battery production, optical film coating, adhesive tape manufacturing, and other fields. Their function is to evenly apply glue or other coating materials to the substrate. The glue tank is a crucial component of the dimple coating head, responsible for storing and supplying glue, ensuring a continuous and stable coating process.

[0003] Existing glue troughs usually adopt an one-piece molding design. Although this design has the advantages of simple structure and easy manufacturing, there are some problems that are difficult to ignore during actual use, especially in cleaning. The internal structure of the glue trough with an one-piece molding design is often more complicated, with many small gaps and corners. These places are prone to accumulate glue residues, solidified materials and other impurities during long-term use. Since these gaps and corners are difficult to directly access, dead corners will be formed during cleaning, and the residues in the glue trough cannot be completely removed, causing glue contamination and deterioration. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a micro-concave coating head glue tank based on a quick assembly and disassembly structure, which can effectively solve the problem in the prior art that the internal structure of the one-piece molded glue tank is relatively complex and there are many small gaps and corners. During long-term use, glue residues, solids and other impurities are easily accumulated. Since these gaps and corners are difficult to directly access, dead corners will be formed during cleaning, and the residues in the glue tank cannot be completely removed, causing glue contamination and deterioration.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a micro-concave coating head glue tank based on a quick assembly and disassembly structure, comprising:

[0007] Glue tank body;

[0009] The glue tank body adopts a detachable structure, which is divided into a U-shaped material storage bin and a baffle plate that can be quickly loaded and unloaded with the material storage bin through a quick loading and unloading part. The left and right ends of the baffle plate are each provided with three locking grooves along the front and rear directions.

[0010] Among them, a sieve plate with chamfered front and rear ends is provided inside the material bin and on the upper surface of the material baffle plate through several reset springs, and two U-shaped filter plates with openings facing each other and magnetically connected to the sieve plate through magnetic parts are provided on the upper surface of the sieve plate.

[0011] Furthermore, mounting plates are fixedly provided on the upper surfaces of the two filter plates, and guide grooves are provided on the end faces of the two mounting plates. Cleaning parts that can be used to clean glue impurities inside the silo are slidably provided inside the two guide grooves.

[0012] Furthermore, the cleaning member includes a mounting rod which is always slidably arranged inside the guide groove and one end of which is connected to the external driving member, and the other end of the mounting rod is fixedly connected to a waist-shaped block with an elliptical groove on its end surface.

[0013] Furthermore, the interior of the waist-shaped block is rotatably connected to two symmetrically arranged C-shaped cleaning scrapers through a sliding block. The lower surfaces of the two cleaning scrapers away from one end are respectively connected to counterweight blocks for maintaining the balance of the cleaning scrapers. A cylindrical float is also arranged below the two cleaning scrapers and between the two counterweight blocks.

[0014] Furthermore, a plurality of pressing rotating parts are provided on the upper surface of the baffle plate and below the sieve plate. The pressing rotating parts include a mounting sleeve that is rotatably arranged on the baffle plate and has a plurality of stirring paddles fixedly arranged on the outer wall along the circumferential direction. A serrated groove is provided on the circumferential inner wall of the mounting sleeve along the circumferential direction. A linkage rod fixedly connected to the top end surface of the lower end surface of the sieve plate is provided inside the mounting sleeve through sliding of a compression spring. A plurality of toggle rods that are always located inside the serrated groove are fixedly connected to the circumferential outer wall of the linkage rod.

[0015] Furthermore, three through slots distributed along the front-to-back direction are opened inside the installation cavity, and sliding blocks are slidably arranged inside the through slots. The sliding blocks are fixedly connected to a support plate that slides through the installation cavity through a strip block arranged on its lower surface.

[0016] Furthermore, the limiting part includes a supporting block slidingly arranged on the upper surface of the sliding block along the front-to-back direction, and three trapezoidal clamping blocks distributed in the front-to-back direction are fixedly connected to the side of the supporting block close to the material blocking plate, and the front and rear side walls of the trapezoidal clamping block are fixedly connected with an elastic top plate, and the other end of the supporting block is fixedly provided with two push blocks distributed along the front-to-back direction and with blocking plates fixedly arranged on the outer side walls, and the push block slides through the installation cavity at the end away from the supporting block.

[0017] Furthermore, the internal rotation of the material storage bin is provided with three stirring rollers distributed in the left and right directions and connected to the external driving member at one end. The circumferential outer walls of the three stirring rollers are respectively provided with a number of cams whose outer walls are in contact with the upper surface of the sieve plate in the front and back directions. The cams arranged on adjacent stirring rollers are staggered, and the front and rear side walls of the material storage bin are provided with linkage groups that can be used to achieve the synchronous approach or distance of the support blocks on both sides.

[0018] Furthermore, the linkage group includes an L-shaped sealing plate which is arranged on the side wall of the material storage bin and is rotated by a torsion spring. An active bevel gear is arranged inside the sealing plate and rotates axially. Linkage parts are arranged inside the sealing plate and at both ends of the active bevel gear.

[0019] Furthermore, the linkage part includes a driven bevel gear which is arranged inside the sealing plate through the rotation of a threaded rod and is always engaged with the driving bevel gear for transmission. The threaded rod is located on the outer wall of the circumference inside the sealing plate and is threadedly connected to a U-shaped linkage block for driving the supporting block to move.

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] The glue trough body of the present invention adopts a modular design to achieve a detachable structure, and is divided into two independent modules, a material storage bin and a material baffle plate, which not only significantly improves the maintainability and disassembly of the equipment, but also simplifies the cleaning of the material storage bin and the material baffle plate. Specifically, the modular design of the material storage bin and the material baffle plate allows maintenance personnel to quickly and conveniently disassemble and assemble the equipment, thereby shortening maintenance time and reducing maintenance costs. The detachable design makes it easier to thoroughly clean the material storage bin and the material baffle plate, which can effectively avoid the accumulation of residues inside the equipment. At the same time, during the coating work, when the sieve plate moves up and down, it drives the filter plate and the scraper provided thereon to move synchronously. The scraper provided on the side wall of the filter plate is in close contact with the inner wall of the material storage bin during movement, thereby scraping off glue that may adhere to the wall surface, which not only avoids the adhesion of glue to the inner wall of the material storage bin, but also prevents the reduction in stirring efficiency due to glue accumulation and the accumulation of residues with potential pollution risks.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example:

[0038] See also Figures 1-11 The present invention provides a technical solution: a micro-concave coating head glue tank based on a quick assembly and disassembly structure, comprising:

[0039] Glue tank body 1;

[0040] The quick-install and remove part 2 includes a mounting cavity 21 that is symmetrically arranged below the glue tank body 1 and is integrally formed with the glue tank body 1. A limit member 22 is slidably provided inside the mounting cavity 21.

[0041] The glue tank body 1 adopts a detachable structure, which is divided into a U-shaped material storage bin 11 and a baffle plate 12 that can be quickly loaded and unloaded with the material storage bin 11 through a quick loading and unloading portion 2. The left and right ends of the baffle plate 12 are each provided with three locking grooves 121 along the front-to-back direction.

[0042] Among them, a sieve plate 111 with chamfered front and rear ends is provided inside the material bin 11 and on the upper surface of the material baffle plate 12 through several return springs, and the upper surface of the sieve plate 111 is provided with two U-shaped filter plates 112 with openings facing each other and magnetically connected to the sieve plate 111 through magnetic parts. The two filter plates 112 are close to one end of the inner wall of the material bin 11 and are provided with several scraping knives 113 along the up and down directions that can be used to scrape and clean the inner wall of the material bin 11.

[0043] A mounting plate is fixedly provided on the upper surface of the two filter plates 112 , and a guide groove 1121 is provided on the end surface of the two mounting plates. Cleaning parts 114 for cleaning glue impurities inside the silo 11 are slidably provided inside the two guide grooves 1121 .

[0044] The cleaning member 114 includes a mounting rod 1141 that is always slidably disposed inside the guide groove 1121 and one end of which is connected to the external driving member. The other end of the mounting rod 1141 is fixedly connected to a waist-shaped block 1142 with an elliptical groove formed on its end surface.

[0045] The interior of the waist-shaped block 1142 is rotatably connected to two C-shaped cleaning scrapers 1143 arranged in symmetrical directions through a sliding block. The lower surfaces of the two cleaning scrapers 1143 away from one end are respectively connected to counterweight blocks for keeping the cleaning scrapers 1143 balanced. A cylindrical float 1144 is also provided below the two cleaning scrapers 1143 and between the two counterweight blocks.

[0046] Several pressing rotating parts 122 are provided on the upper surface of the baffle plate 12 and below the sieve plate 111. The pressing rotating part 122 includes a mounting sleeve 1221 which is rotatably set on the baffle plate 12 and has several stirring paddles 1222 fixedly provided on the outer wall along the circumferential direction. A serrated groove is provided on the circumferential inner wall of the mounting sleeve 1221 along the circumferential direction. A linkage rod 1223 is slidingly provided inside the mounting sleeve 1221 with a top end fixedly connected to the lower end surface of the sieve plate 111 through a compression spring. The circumferential outer wall of the linkage rod 1223 is fixedly connected to several toggle rods 1224 that are always located inside the serrated groove.

[0047] The interior of the installation cavity 21 is provided with three through slots distributed along the front-to-back direction. Sliding blocks are slidably arranged inside the through slots. The sliding blocks are fixedly connected to a support plate 211 that slides through the installation cavity 21 through a strip block arranged on the lower surface thereof.

[0048] The limiting member 22 includes a supporting block 221 which is slidably arranged on the upper surface of the sliding block along the front-to-back direction. The supporting block 221 is fixedly connected to one side close to the material blocking plate 12 with three trapezoidal blocks 222 distributed in the front-to-back direction. The front and rear side walls of the trapezoidal block 222 are fixedly connected with an elastic top plate. The other end of the supporting block 221 is fixedly provided with two push blocks 223 which are distributed along the front-to-back direction and have blocking plates fixed on the outer side walls. The push block 223 slides through the installation cavity 21 at the end away from the supporting block 221.

[0049] The internal rotation of the material storage bin 11 is provided with three stirring rollers distributed in the left-right direction and connected to the external driving member at one end. The circumferential outer walls of the three stirring rollers are provided with a plurality of cams 115 whose outer walls are in contact with the upper surface of the sieve plate 111 in the front-to-back direction. The cams 115 arranged on adjacent stirring rollers are staggered. The front and rear side walls of the material storage bin 11 are provided with a linkage group 116 that can be used to achieve the synchronous approach or distance of the support blocks 221 on both sides.

[0050] The linkage group 116 includes an L-shaped sealing plate 1161 which is rotatably arranged on the side wall of the material storage bin 11 by a torsion spring. An axially rotating driving bevel gear is arranged inside the sealing plate 1161. Linkage parts are arranged inside the sealing plate 1161 and at both ends of the driving bevel gear.

[0051] The linkage part includes a driven bevel gear that is rotatably arranged inside the sealing plate 1161 and is always engaged with the driving bevel gear for transmission through a threaded rod 1162. The threaded rod 1162 is located on the outer circumferential wall inside the sealing plate 1161 and is threadedly connected to a U-shaped linkage block 1163 for driving the supporting block 221 to move.

[0052] During the specific work, the quick installation of the baffle plate 12:

[0053] First, move the baffle plate 12 between the left and right installation cavities 21, and align the left and right ends of the baffle plate 12 with the side walls of the two installation cavities 21 respectively (in the initial state, since the material storage bin 11 and the baffle plate 12 are in a separated state, the baffle plate 12 needs to be pushed between the two installation cavities 21 to complete the assembly of the entire glue tank body 1), and then push the baffle plate 12 and slide it into the two installation cavities 21 in the front and rear directions (the upper surface of the baffle plate 12 is provided with a sieve plate 111 by a number of return springs. Therefore, in the process of pushing the baffle plate 12 in, the sieve plate 111 first contacts the material storage bin 11, and in the process of contact, the height of the sieve plate 111 is lowered by the chamfer on the sieve plate 111 and the compression return spring of the material storage bin 11). When the sieve plate 111 moves to the predetermined position, the compression force on the front and rear ends of the return spring under the sieve plate 111 disappears, and the return spring quickly releases its stored elastic potential energy, driving the sieve plate 111 to rebound, and finally making the upper surface of the sieve plate 111 after rebound fit with the outer wall of the cam 115 fixedly connected to the outer wall of the stirring roller. In this process, the sieve plate 111 is pushed into the material bin 11, ensuring that the position between the material bin 11 and the material baffle plate 12 will not be misaligned due to excessive or insufficient force applied during the process of pushing the material baffle plate 12 to work. The automatic return of the sieve plate 111 is achieved by the set return spring, which effectively avoids the problems caused by unstable operating force. On the premise of ensuring precise positioning between the two, the stability and reliability of the equipment are further improved.

[0054] When the material baffle plate 12 reaches the predetermined position and completes the initial positioning, the sealing plates 1161 on the front and rear side walls of the material storage bin 11 are synchronously controlled to flip downward 90 degrees. As the sealing plate 1161 flips, its side walls and lower ends will gradually move and fit respectively with the side walls and lower surface of the material baffle plate 12, thereby completing the support work on the front and rear ends of the material baffle plate 12 (the two sealing plates 1161 are arranged in an L shape and are respectively installed on the side walls of the material storage bin 11. In the initial state, elastic clamping parts are fixedly provided on the side walls where the vertical sections of the two sealing plates 1161 are close to each other. The design purpose is that as the sealing plate 1161 flips, the elastic clamping parts will be blocked by the material baffle plate 12, thereby causing compression deformation. As the elastic clamping parts are gradually compressed, their clamping force on the lower surfaces of the front and rear sides of the material baffle plate 12 will be further increased).

[0055] Specifically, when the sealing plate 1161 is flipped around its rotation axis, its vertical section will gradually approach the material storage bin 11. At this time, the elastic pressing member fixed on the vertical section of the sealing plate 1161 will contact the lower surface of the material baffle plate 12 and will be gradually compressed as the sealing plate 1161 is flipped. Due to the elastic characteristics of the elastic pressing member, a reaction force will be generated during the compression process. The reaction force will act on the lower surface of the material baffle plate 12, thereby generating an upward pressing force on the material baffle plate 12. As the flipping angle of the sealing plate 1161 increases, the compression amount of the elastic pressing member also increases. , its clamping force on the baffle plate 12 also increases accordingly. The elastic clamping member is set to ensure that the baffle plate 12 can maintain a stable position when subjected to material pressure or other external forces, avoiding displacement or tilting. At the same time, due to the presence of the elastic clamping member, the connection between the baffle plate 12 and the sealing plate 1161 is also stronger, thereby improving the reliability and stability of the entire device). At the same time, when the two sealing plates 1161 are synchronously flipped, the U-shaped linkage block 1163 on the same sealing plate 1161 is also synchronously clamped into the two ends of the support block 221 inside the installation cavity 21.

[0056] Then, an electric tool is used to synchronously drive the active bevel gears (not shown in the drawings of the specification) inside the front and rear sealing plates 1161 to rotate. Taking any sealing plate 1161 as an example, the active bevel gears are respectively engaged during the rotation process to drive the driven bevel gears on the left and right sides (not shown in the drawings of the specification) to rotate. During the rotation of the two driven bevel gears, the threaded rods 1162 respectively drive the corresponding linkage blocks 1163 to move, and during the movement of the linkage blocks 1163, the support block 221 and the material blocking plate 12 are tightened (after the sealing plate 1161 completes the flipping action, the support block 221 is accurately locked into the internal space of the linkage block 1163). With the rotation of the threaded rod 1162, the linkage block 1163 will synchronously drive the support block 221 to move along the installation cavity 21. During the movement of the support block 221, the trapezoidal block 222 will enter the corresponding locking groove 121, and the trapezoidal block 222 and the elastic top plate connected thereto will work together When the locking plate 12 is in the unlocking state, the locking plate 12 is locked and the locking plate 12 is locked.

[0057] During the process of injecting glue into the glue tank body 1, a certain pressure will be generated on the material baffle plate 12, trying to push it open. However, through the coordinated action of the sealing plate 1161, the elastic clamping member, the trapezoidal block 222 and the support plate 211, multi-directional support and clamping of the material baffle plate 12 are achieved, ensuring that during the subsequent glue injection process, the material baffle plate 12 can remain stable and avoid shaking or falling off due to the action of glue pressure.

[0058] Specifically, after the sealing plate 1161 is flipped over, the elastic pressure member provided on it will be in close contact with the material blocking plate 12, providing an initial pressure. As the threaded rod 1162 rotates, the linkage block 1163 drives the supporting block 221 to move, and the trapezoidal block 222 enters the locking groove 121, and through its special geometric shape and the action of the elastic top plate, further enhances the pressure of the material blocking plate 12 in the left and right directions. At the same time, under the drive of the sliding block and the bar block, the upper surface of the support plate 211 is tightly fitted with the lower surface of the material blocking plate 12, providing vertical support force. This multi-directional support and pressure mechanism can effectively resist the pressure generated during glue injection. Since the material blocking plate 12 is constrained by the elastic pressure and trapezoidal block 222 in the left and right directions, and supported by the support plate 211 in the vertical direction, it can maintain a stable position during work and will not shake or fall off.

[0059] Installation of the filter plate 112 and use of the glue tank body 1:

[0060] When the baffle plate 12 completes the limiting work, the two filter plates 112 are inserted into the baffle plate 12 in a relative manner from the top of the material bin 11, and the two filter plates 112 are electromagnetically fixed to the baffle plate 12 respectively (the two filter plates 112 are close to the inner wall of the material bin 11. Several scrapers 113 are provided in the up and down directions. When the filter plate 112 is inserted into the baffle plate 12 in the vertical direction, ensure that the blade of the scraper 113 is in contact with the inner wall of the material bin 11 to ensure the smooth progress of the subsequent scraping work). After the two filter plates 112 are installed, glue is injected into the material bin 11. Since a float 1144 is provided under the two cleaning scrapers 1143, the two cleaning scrapers 1143 will not sink into the glue after the glue injection is completed.

[0061] When the glue tank body 1 performs the coating operation, the three stirring rollers configured inside the material storage bin 11 realize synchronous rotation under the power provided by the external driving member. This rotational movement not only effectively prevents the solidification problem of the glue inside the glue tank body 1 due to stillness, and maintains the continuous flow state of the glue, but also realizes the intermittent push of the sieve plate 111 through the synchronous rotation of several cams 115 evenly distributed on the outer wall of the stirring roller. The sieve plate 111 moves downward under the push of the cam 115, and the linkage rod 1223 is also synchronously rotated. The plurality of toggle rods 1224 arranged on the outer wall thereof slide along the serrated grooves. The precise fit between the toggle rods 1224 and the serrated grooves drives the rotation of the mounting sleeve 1221 and the stirring paddle 1222 fixed thereon. The rotational movement of the stirring paddle 1222 installed on the outer wall of the sleeve achieves effective stirring of the glue at the bottom of the glue tank body 1. This stirring action complements the rotational movement of the three stirring rollers, further enhancing the stirring effect of the glue inside the glue tank body 1 and ensuring the uniformity and fluidity of the glue.

[0062] It should be noted that, since the filter plate 112 with two side walls provided with scrapers 113 is fixed on the sieve plate 111 by magnetic connection, when the sieve plate 111 is performing up and down reciprocating motion, the scraper 113 can effectively scrape the inner wall of the material storage bin 11. This design is intended to eliminate dead angles that may exist during the stirring process and prevent glue from adhering to and accumulating on the inner wall of the material storage bin 11. Specifically, the up and down reciprocating motion of the sieve plate 111 drives the filter plate 112 magnetically connected to it to move synchronously. The scraper 113 provided on the side wall of the filter plate 112 is in close contact with the inner wall of the material storage bin 11 during the movement, thereby scraping off the glue adhering to the wall. This scraping action not only avoids the adhesion of glue to the inner wall of the material storage bin 11, but also prevents the reduction of stirring efficiency and potential pollution risks caused by glue accumulation.

[0063] During the coating work, it is inevitable that some impurities or oily materials will contaminate the glue. At this time, the two mounting rods 1141 are synchronously driven by an external driving member to slide along the guide groove 1121, driving the two cleaning scrapers 1143 to move. Since a cylindrical float 1144 is provided under the two cleaning scrapers 1143, the scrapers can always float on the upper surface of the glue inside the glue tank body 1. In the process of moving on the glue surface, the cleaning scrapers 1143 effectively collect the floating impurities and oily substances. As the mounting rod 1141 continues to move backward along the guide groove 1121, the height of the guide groove 1121 gradually increases, and the two cleaning scrapers 1143 are gradually lifted up and finally separated from the glue tank body 1. Since the two cleaning scrapers 1143 are connected to the sliding block in a rotating manner, and the lower surface of the scraper is The surfaces are respectively connected with counterweights, so even if the scraper is separated from the glue, it can still maintain a balanced state to avoid overturning or flipping. When the mounting rod 1141 moves to the rear end of the guide groove 1121, the cleaning scraper 1143 cooperates with the external top plate to trigger the rotation of the scraper. Through the cooperation of the guide groove 1121 and the mounting rod 1141, the cleaning scraper 1143 can continuously collect and automatically clean impurities and oily substances on the surface of the glue. The float 1144 design of the cleaning scraper 1143 ensures that it is always located on the glue surface, and the use of counterweights ensures the stability of the scraper after it is separated from the glue. The variable height design of the guide groove 1121 realizes the automatic lifting and separation of the scraper. Finally, through the cooperation with the external top plate, the rotation of the scraper and the automatic falling of impurities into the collection box are realized, realizing the automatic cleaning and collection of impurities.

[0064] It should be noted that the cleaning scraper 1143 is slidably arranged inside the elliptical groove of the waist-shaped block 1142 through a sliding block, and its purpose is to adapt to the changes in the different heights of the glue inside the glue tank body 1.

[0065] Quick disassembly of the baffle plate 12:

[0066] When the glue tank body 1 needs to be cleaned, it is only necessary to use an electric tool to synchronously drive the driving bevel gears inside the front and rear sealing plates 1161 to rotate, and the driving bevel gears respectively drive the driven bevel gears on both sides to rotate. In the process of rotation of the driven bevel gears, the supporting block 221 and the support plate 211 are synchronously driven away from the material baffle plate 12 through the linkage block 1163, and then the sealing plates 1161 on both sides are flipped to the initial position, and finally the material baffle plate 12 that lacks tightness and support can be taken out downwards.

[0067] It should be noted that the glue tank body 1 adopts a detachable structure and divides the glue tank body 1 into two modules: a material storage bin 11 and a material baffle plate 12. This is not only convenient for assembly and maintenance, but the detachable design also makes the material storage bin 11 and the material baffle plate 12 easier to clean, which can effectively avoid residue accumulation and reduce the risk of pollution.

[0068] The glue tank body 1 adopts a modular design to achieve a detachable structure, and is divided into two independent modules: a material storage bin 11 and a material baffle plate 12. This not only significantly improves the maintainability and disassembly of the equipment, but also simplifies the cleaning of the material storage bin 11 and the material baffle plate 12. Specifically, the modular design of the material storage bin 11 and the material baffle plate 12 allows maintenance personnel to quickly and conveniently disassemble and assemble the equipment, thereby shortening maintenance time and reducing maintenance costs. At the same time, the detachable design makes it easier to thoroughly clean the material storage bin 11 and the material baffle plate 12, which can effectively avoid the accumulation of residues inside the equipment. The accumulation of residues will not only affect the quality of the glue and the coating effect, but may also increase the risk of contamination and even cause equipment failure.

[0069] It is worth emphasizing that the micro-concave coating head glue tank based on the quick loading and unloading structure has the following main advantages:

[0070] Advantage 1: The glue tank body 1 adopts a modular design to achieve a detachable structure, and is divided into two independent modules: a material storage bin 11 and a material baffle 12. This not only significantly improves the maintainability and disassembly of the equipment, but specifically, the modular design of the material storage bin 11 and the material baffle 12 allows maintenance personnel to quickly and conveniently disassemble and assemble the equipment, thereby shortening maintenance time and reducing maintenance costs. The detachable design makes it easier to thoroughly clean the material storage bin 11 and the material baffle 12, and can effectively avoid the accumulation of residues inside the equipment. At the same time, during the coating work, when the sieve plate 111 reciprocates up and down, it drives the filter plate 112 and the scraper 113 arranged thereon to move synchronously. The scraper 113 arranged on the side wall of the filter plate 112 is in close contact with the inner wall of the material storage bin 11 during movement, thereby scraping off the glue that may adhere to the wall surface, which not only avoids the adhesion of glue to the inner wall of the material storage bin 11, but also prevents the reduction of stirring efficiency and the accumulation of residues with potential pollution risks caused by glue accumulation.

[0071] Advantage 2: The three stirring rollers configured inside the material storage bin 11 rotate synchronously under the power provided by the external driving member, maintaining the continuous flow state of the glue. The intermittent push of the sieve plate 111 is achieved through the synchronous rotation of several cams 115 evenly distributed on the outer wall of the stirring roller. The sieve plate 111 and the linkage rod 1223 move downward under the push of the cam 115. Several toggle rods 1224 slide along the zigzag groove and then drive the rotation of the mounting sleeve 1221 and the stirring paddle 1222 fixed thereon, and finally complete the stirring paddle 1222 on the glue tank body 1 The glue at the bottom is effectively stirred. At the same time, when the sieve plate 111 is performing up and down reciprocating motion, the scraper 113 can effectively scrape the inner wall of the silo 11, eliminating the dead angle that may exist during the stirring process, and preventing the glue from adhering to and accumulating on the inner wall of the silo 11. The scraper 113 arranged on the side wall of the filter plate 112 is in close contact with the inner wall of the silo 11 during the movement, thereby scraping off the glue that may adhere to the wall surface, which not only avoids the adhesion of glue to the inner wall of the silo 11, but also prevents the reduction of stirring efficiency and potential pollution risks caused by glue accumulation.

[0072] Advantage three, when the supporting block 221 moves under the drive of the linkage block 1163, due to the special shape of the trapezoidal blocking block 222, after entering the locking groove 121, it will be constrained by the side of the locking groove 121, thereby squeezing the elastic top plate and causing the elastic top plate to retract, and the reaction force of the elastic top plate is pushed against the side of the baffle plate 12, thereby achieving tight support for the baffle plate 12. At the same time, in order to ensure stable support of the baffle plate 12, the supporting block 221 also drives the support plate 211 to slide synchronously through the linkage of the sliding block and the strip block during the movement. During the sliding process, the upper surface of the support plate 211 remains in close contact with the lower surface of the baffle plate 12, thereby achieving effective support for the lower surface of the baffle plate 12.

[0073] Advantage 4: the two mounting rods 1141 are driven to slide along the guide groove 1121, driving the two cleaning scrapers 1143 to move. Since cylindrical floats 1144 are provided below the two cleaning scrapers 1143, the scrapers can always float on the upper surface of the glue inside the glue tank body 1. In the process of moving on the glue surface, the cleaning scrapers 1143 effectively collect floating impurities and oily substances. As the mounting rods 1141 continue to move backward along the guide groove 1121, the height of the guide groove 1121 gradually increases, and the two cleaning scrapers 1143 are gradually lifted up. Finally, it separates from the glue tank body 1. Since the two cleaning scrapers 1143 are connected to the sliding block in a rotating manner, and the lower surfaces of the scrapers are respectively connected to counterweight blocks, even if the scrapers are separated from the glue, they can still maintain a balanced state to avoid overturning or flipping. When the mounting rod 1141 moves to the rear end of the guide groove 1121, the cleaning scraper 1143 cooperates with the external top plate to trigger the rotation of the scraper. Through the cooperation between the guide groove 1121 and the mounting rod 1141, the cleaning scraper 1143 can continuously collect and automatically clean impurities and oily substances on the surface of the glue.
