Description

Technical Field

[0001] The present application relates to the field of glass fiber cloth composite, and in particular to a glass fiber cloth composite coating machine. Background Art

[0002] Safety shoes are shoes used to protect the wearer's feet from hazards in the work area or to keep the work area safe.

[0003] Safety shoe toes are usually made of composite fiberglass cloth to ensure the compressive strength and impact resistance of the toes.

[0004] Reference Figure 1 The composite glass fiber cloth is composed of a glass fiber cloth layer 70 and two PE film layers 80, and the two PE film layers are located on both sides of the glass fiber cloth layer. When the glass fiber cloth is composited, it is necessary to use a composite device to unwind the glass fiber cloth and the PE film respectively through three unwinding mechanisms, then apply glue on the PE film, and then the glass fiber cloth and the two PE films are extruded, bonded and composited, and finally rolled into shape.

[0005] When gluing the PE film, a gluing roller is used for gluing. The amount of glue adhering to the gluing roller is not fixed. Therefore, when the gluing roller contacts the PE film for gluing, the amount of glue on the surface of the PE film is not uniform, which affects the composite effect. Summary of the invention

[0006] In order to improve the composite effect and ensure the normal transportation of the PE film, the present application provides a glass fiber cloth composite coating machine.

[0007] The glass fiber cloth composite coating machine provided in this application adopts the following technical solution:

[0008] A glass fiber cloth composite coating machine comprises a machine body, on which a glass fiber cloth unwinding mechanism, two PE film unwinding mechanisms, two glue coating mechanisms, an extrusion composite mechanism and a winding mechanism are arranged, and a plurality of guide rollers are also arranged on the machine body, which play a conveying and guiding role for the conveying of the glass fiber cloth and the PE film, and the glue coating mechanism is used to glue the PE film, and the glue coating mechanism comprises a glue coating roller and a scraper, the glue coating roller is rotatably connected to the machine body, the scraper is arranged on one side of the glue coating roller, and the lower end of the scraper is formed with an inclined The scraper part is arranged obliquely upward along the conveying direction of the PE film, the scraper plate is provided with a glue inlet on the upper side of the scraper part, a mounting groove is provided in the scraper plate, the glue inlet is communicated with the mounting groove, the scraper plate is provided with a conveyor belt in a closed loop in the mounting groove, the conveyor belt extends out of the scraper plate, a scraper plate is provided on one side of the machine body in the length direction of the scraper plate in the vertical direction, the scraper plate abuts against the lower side of the conveyor belt extending out of the scraper plate end, and a glue box is provided on the machine body at the lower side of the scraper plate.

[0009] By adopting the above technical scheme, the glass fiber cloth unwinding mechanism unwinds the glass fiber cloth, the two PE film unwinding mechanisms unwind the PE films, the two glue coating structures correspond to the two PE films one by one, the glue coating mechanism coats the corresponding PE films with glue, and finally the glass fiber cloth and the two PE films are bonded and composited at the extrusion and composite mechanism to form a composite glass fiber cloth, which is finally formed and rolled up on the rewinding mechanism; after the glue coating roller has finished gluing the PE film, the scraper will scrape the glue on the surface of the PE film to make the glue liquid evenly distributed, which is helpful to improve the subsequent composite effect; in the process of continuous scraping, the glue liquid will gradually accumulate, and will gradually fall from the glue inlet onto the conveyor belt along the inclined scraping part, the conveyor belt drives the glue liquid to be transported to the outside of the scraper plate, and is scraped off the conveyor belt at the scraper plate, at this time, the glue liquid will fall from the scraper plate into the glue box, and in this way, the glue liquid can be prevented from accumulating on the PE film, and the glue box collects the glue liquid for secondary use to prevent the glue liquid from being wasted.

[0010] Preferably, a glue delivery shaft is provided on the machine body, the glue coating roller is rotatably connected to the glue delivery shaft, a glue delivery hole is provided in the glue delivery shaft, one end of the glue delivery hole is connected with external glue, a plurality of glue outlets are provided on the glue delivery shaft, a plurality of glue extrusion outlets are provided in an array on the circumference of the glue coating roller, a glue extrusion plate is slidably provided at the glue extrusion outlet of the glue coating roller, and a driving member for driving the glue extrusion plate to slide is provided on the glue delivery shaft; when the glue coating roller rotates, before the glue extrusion outlet contacts the PE film, the driving member drives the glue extrusion plate at the glue extrusion outlet to slide inward, and when the glue extrusion outlet contacts the PE film, the glue extrusion plate slides outward and squeezes the glue onto the surface of the PE film.

[0011] By adopting the above technical scheme, the glue enters the glue coating roller from the glue outlet on the glue delivery shaft. When the glue coating roller rotates, before the glue coating outlet on the glue coating roller contacts the PE film, that is, at this time, the glue coating outlet is at a certain tilt angle, the driving member drives the glue squeezing plate to slide inward, and the glue squeezing outlet is exposed. At this time, the glue in the glue coating roller will converge to the glue squeezing outlet, and then when the glue squeezing outlet contacts the PE film, the glue squeezing plate slides outward to squeeze the glue onto the surface of the PE film to achieve the gluing action. During the rotation of the glue coating roller, the PE film can be continuously glued. Because the glue squeezing outlets are distributed at intervals, the glue on the PE film will also be distributed at intervals. Subsequently, under the action of the scraper plate, the glue can be continuously and evenly distributed on the PE film.

[0012] Preferably, the driving member is configured as a driving wheel, which is coaxially fixed on the rubber delivery shaft, and the driving wheel is provided with a concave wheel portion, and the concave wheel portion is located on a side close to the unwinding end of the PE film, a sliding sleeve is provided in the glue coating roller, and the rubber extrusion plate slides in the sliding sleeve, and sliding grooves are provided on both side walls of the sliding sleeve, and sliding blocks are provided on both side edges of the rubber extrusion plate, and the sliding blocks slide in the corresponding sliding grooves, and the sliding sleeve is provided with an abutment spring in the sliding groove, one end of the abutment spring is connected to the sliding block, and the other end of the sliding block is connected to the inner wall of the sliding groove, and a connecting rod is provided on the rubber extrusion plate, the connecting rod is located on a side close to the rubber delivery shaft, and the connecting rod passes through the sliding sleeve, and the end of the connecting rod is rotatably connected to an abutment wheel, and the abutment wheel is always abutted against the driving wheel.

[0013] By adopting the above technical solution, in practice, the glue coating roller is driven by the motor and the pulley mechanism to rotate slowly to adapt to the conveying rate of the PE film. The glue coating roller rotates, but the glue delivery shaft does not rotate. Therefore, the abutment wheel moves around the driving wheel. When the abutment wheel moves to the concave part, under the action of the abutment spring, the sliding block drives the glue squeezing plate to slide inward. When the abutment wheel is disengaged from the concave part, the glue squeezing plate is reset, that is, it slides outward to realize the glue squeezing action.

[0014] Preferably, the extrusion composite mechanism includes a lower pressure roller and an upper pressure roller, the lower pressure roller is rotatably connected to the machine body, and the upper pressure roller is lifted and lowered at the upper side of the lower pressure roller, and the machine body is provided with vertical mounting plates on both sides of the upper pressure roller, and a sliding groove is provided on the mounting plate in the vertical direction, and the mounting plate is slidably connected with a sliding block in the sliding groove, and the two ends of the upper pressure roller are rotatably connected to the two sliding blocks, and the mounting plate is also slidably connected with a connecting block in the sliding groove, and the connecting block and the sliding block are connected by a compression spring, and a driving cylinder is installed on the machine body, and the driving cylinder is vertically arranged downward, and the piston rod end of the driving cylinder is fixedly connected to the connecting block.

[0015] By adopting the above technical solution, the glass fiber cloth and the two PE films enter between the upper pressure roller and the lower pressure roller for extrusion and compounding. The connecting block is driven to descend by the driving cylinder. When the connecting block descends, the compression spring is compressed, that is, the force acting on the sliding block changes, so that the extrusion pressure of the lower pressure roller changes, and the extrusion pressure can be adjusted to ensure the compounding effect.

[0016] Preferably, a driving motor is fixedly mounted on the machine body, a first pulley is coaxially fixed on the output shaft of the driving motor, both ends of the rubber coating roller are fixedly connected with a rotating shaft, the rotating shaft rotates with the machine body, a second pulley is coaxially fixed on one of the rotating shafts, and belts are wound around the first pulley and the second pulley.

[0017] By adopting the above technical solution, the motor is driven to operate, and the rotation of the glue coating roller can be achieved through the first pulley, the second pulley and the belt.

[0018] Preferably, the body is provided with fixed plates in the vertical direction at both ends of the glue coating roller, a floating groove is opened on the fixed plate in the vertical direction, a rotating plate is slidably provided in the floating groove, the two rotating shafts correspond one to one with the two rotating plates, and the rotating shaft is connected to the corresponding rotating plates, a floating wheel is coaxially fixed on the rotating shaft, a plurality of cam portions are arranged in a circular array on the floating wheel, the number of the cam portions is the same as the number of the glue extrusion ports and corresponds one to one, a supporting wheel is rotatably connected to the fixed plate, and the supporting wheel is always in contact with the floating wheel.

[0019] By adopting the above technical scheme, during the rotation of the glue coating roller, the floating wheel rotates synchronously therewith, and when the cam portion on the floating wheel contacts the supporting wheel, the floating wheel will drive the glue coating roller to move upward, and when the cam portion is separated from the supporting wheel, the floating wheel will reset, and when the glue coating roller moves upward, the glue extrusion port is just facing downward, that is, the glue extrusion operation is carried out at this time; if the glue coating roller is always in contact with the PE film, then when the glue extrusion plate slides to squeeze glue, part of the glue liquid will flow back into the glue coating roller, resulting in a small amount of glue output, and there will be glue liquid adhering to the surface of the glue coating roller, affecting the glue coating effect. In this application, the glue liquid can be recovered by scraping glue later, so during the glue coating process, even if the amount of glue applied is large, there will be no waste of glue liquid; therefore, when the glue extrusion port is facing downward and glue is squeezed onto the PE film, the glue coating roller rises, and a certain space is generated between the glue coating roller and the PE film, thereby ensuring the amount of glue applied.

[0020] Preferably, the scraper plate is located in the installation groove and is rotatably connected to the first conveying roller, the scraper plate is rotatably connected to the second conveying roller outside, the conveyor belt is wound around the first conveying roller and the second conveying roller, and a drive motor is installed on the scraper plate, and the drive motor drives the first conveying roller to rotate.

[0021] By adopting the above technical solution, the driving motor drives the first conveying roller to rotate, and the first conveying roller cooperates with the second conveying roller to drive the conveyor belt to move, thereby conveying the glue liquid.

[0022] Preferably, the scraper plate is located in the installation groove and is also provided with an inclined guide plate, and the guide plate is located at the glue inlet, and the guide plate is inclined downward from the glue inlet toward the conveyor belt, and the bottom of the guide plate shields the edge of the conveyor belt.

[0023] By adopting the above technical solution, when the glue enters the installation groove from the glue inlet, the glue will gradually slide from the guide plate to the conveyor belt. The lower bottom of the guide plate shields the edge of the conveyor belt, which can prevent the glue on the guide plate from dripping to the edge of the conveyor belt, causing the glue to accumulate in the installation groove.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. After applying glue on the PE film, the glue can be evenly scraped by the scraper to ensure the subsequent composite effect, and the excess glue can be scraped off. The excess glue will gradually enter the installation groove from the glue inlet along the scraper part, and finally fall onto the conveyor belt. The conveyor belt conveys the glue, and the scraper scrapes the glue on the conveyor belt and makes the glue fall into the glue box, so as to realize the recycling of the glue;

[0026] 2. When the glue roller rotates, when the abutment wheel rotates to the concave part of the driving wheel, under the action of the abutment spring, the abutment wheel enters the concave part, and the glue extrusion plate slides inward, and the glue liquid gradually gathers to the glue extrusion port. When the glue extrusion port contacts the PE film, the glue extrusion plate slides outward to squeeze the glue liquid to the surface of the PE film;

[0027] 3. When the glue coating roller rotates, the floating wheel rotates accordingly. When the cam part of the floating wheel contacts the supporting wheel, the floating wheel drives the glue coating roller to rise. At this time, the glue squeezing plate slides and squeezes the glue to the surface of the PE film. In this way, the glue can be prevented from flowing back and the glue on the PE film can be prevented from adhering to the surface of the glue coating roller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following is combined with Figure 2-Figure 10 This application is described in further detail.

[0040] The embodiment of the present application discloses a glass fiber cloth composite coating machine.

[0041] Reference Figure 2 The glass fiber cloth composite coating machine includes a body 1, on which are arranged a glass fiber cloth unwinding mechanism 2, two PE film unwinding mechanisms 3, two glue coating mechanisms 4, an extrusion composite mechanism 5 and a winding mechanism 6, wherein the glass fiber cloth unwinding mechanism 2 and the two PE film unwinding mechanisms 3 are the same, and both perform unwinding operations through unwinding reels, and the winding mechanism 6 performs winding operations through a winding reel. Since the unwinding mechanism and the winding mechanism 6 are conventional means, they are not described in detail in this application. A plurality of guide rollers 11 are also arranged on the body 1 to guide and convey the glass fiber cloth and the PE film.

[0042] An upper space 12 and a lower space 13 are formed on the machine body 1, wherein a PE film unwinding mechanism 3 is located in the lower space 13, and another PE film unwinding mechanism 3 is located in the upper space 12, and a glass fiber cloth unwinding mechanism 2 is located in the upper space 12, and two gluing mechanisms 4 correspond to two PE films respectively, and perform gluing operations on the corresponding PE films respectively, wherein one gluing mechanism 4 is located in the lower space 13, and the other gluing mechanism 4 is located in the upper space 12; after gluing, the glass fiber cloth and the two PE films are compounded at the extrusion compounding mechanism 5 to form a composite glass fiber cloth, and the extrusion compounding mechanism 5 and the winding mechanism 6 are both located in the lower space 13.

[0043] Reference Figure 2 and Figure 3 The structures and principles of the two glue coating mechanisms 4 are the same. One of them is now used as an example for explanation. The glue coating mechanism 4 includes a glue coating roller 41 and a scraper plate 42. The body 1 is provided with a fixing plate 14 on both sides of the glue coating roller 41. The glue coating roller 41 is rotatably connected to the fixing plate 14. The scraper plate 42 is located on one side of the glue coating roller 41. An inclined scraper portion 421 is formed at the lower end of the scraper plate 42. The scraper portion 421 is inclined upwardly arranged along the conveying direction of the PE film. The scraper plate 42 is located on the upper side of the scraper portion 421. There is a glue inlet 422, and a mounting groove 7 is opened in the scraper plate 42. The glue inlet 422 is connected to the mounting groove 7. A conveyor belt 71 is arranged in a closed loop in the mounting groove 7. One end of the conveyor belt 71 extends out of the scraper plate 42. A scraper plate 81 is arranged on one side of the body 1 in the length direction of the scraper plate 42. The scraper plate 81 is arranged vertically, and the scraper plate 81 abuts against the lower side of one end of the conveyor belt 71 extending out of the scraper plate 42. A glue box 8 is fixedly installed on the body 1. In practice, the scraper plate 81 is fixedly installed at the opening of the glue box 8.

[0044] Reference Figure 3 and Figure 4 The scraper plate 42 is located in the installation groove 7 and is rotatably connected to the first conveying roller 72. The outer side of the scraper plate 42 is rotatably connected to the second conveying roller 73. The conveying belt 71 is wound around the first conveying roller 72 and the second conveying roller 73. The scraper plate 42 is installed with a driving motor 423, which drives the first conveying roller 72 to rotate. The driving motor 423 runs to drive the first conveying roller 72 to rotate, and cooperates with the second conveying roller 73 to realize the movement of the conveying belt 71.

[0045] During the scraping process of the scraper 42, the glue liquid will accumulate at the scraper portion 421, and will gradually fall from the glue inlet 422 along the inclined scraper portion 421 onto the conveyor belt 71. The conveyor belt 71 drives the glue liquid to be transported outside the scraper 42, and is scraped off the conveyor belt 71 at the scraper plate 81. Thereafter, the glue liquid falls from the scraper plate 81 into the glue box 8 to be recycled for secondary utilization, thereby preventing the glue liquid from being wasted.

[0046] Reference Figure 3 and Figure 5 The scraper plate 42 is located in the installation groove 7 and is also integrally formed with an inclined guide plate 74. The guide plate 74 is located at the glue inlet 422. The guide plate 74 is inclined downward from the glue inlet 422 to the direction of the conveyor belt 71, and the bottom of the guide plate 74 shields the edge of the conveyor belt 71. When the glue enters the installation groove 7 from the glue inlet 422, the glue will slide along the inclined surface of the guide plate 74 to the conveyor belt 71. The bottom of the guide plate 74 shields the edge of the conveyor belt 71, which can prevent the glue from dripping to the edge of the conveyor belt 71 and then falling from the conveyor belt 71 to the installation groove 7.

[0047] Reference Figure 3 and Figure 6 , a rotating shaft 9 is integrally formed at both ends of the glue coating roller 41, and a floating groove 141 is opened on the two fixed plates 14 in the vertical direction. The fixed plate 14 is located in the floating groove 141 and is slidably matched with a rotating plate 142. The two rotating shafts 9 and the two rotating plates 142 correspond to each other one by one, and the rotating shaft 9 is rotatably connected with the corresponding rotating plates 142; a driving motor 15 is installed on the body 1, and a first pulley 151 is coaxially fixed on the output shaft of the driving motor 15, and a second pulley 91 is coaxially fixed on one of the rotating shafts 9, and a belt 92 is wound around the first pulley 151 and the second pulley 91, and a tensioning mechanism for tensioning the belt 92 is installed on the body 1. The tensioning mechanism is a conventional technology and is not shown in the figure; when the driving motor 15 is running, the slow rotation of the glue coating roller 41 can be achieved through the first pulley 151, the second pulley 91 and the belt 92.

[0048] Reference Figure 3 , Figure 7 and Figure 8 The body 1 is provided with a glue feeding shaft 10, which is lifted and lowered on the fixed plate 14, and a square shaft portion is formed on the glue feeding shaft 10, which forms a sliding fit with the fixed plate 14, and the glue feeding shaft 10 can only be lifted and lowered but not rotated; the glue feeding shaft 10 is inserted into the glue coating shaft from the rotating shaft 9, and the glue feeding shaft 10 and the glue coating roller 41 are rotated in cooperation. A glue feeding hole 101 is provided in the glue feeding shaft 10, and one end of the glue feeding hole 101 is connected to the external glue liquid. The glue feeding shaft 10 is also provided with a plurality of glue outlets 102 along the length direction, and the glue outlets 102 are connected to the glue feeding hole 101, and the glue liquid is introduced into the glue feeding hole 101, and the glue liquid enters the glue coating roller 41 from the glue outlet 102.

[0049] The glue coating roller 41 is provided with a glue extrusion port 411 in a circumferential array, and a glue extrusion plate 20 is slidably arranged at the glue extrusion port 411 of the glue coating roller 41, and a driving member for driving the glue extrusion plate 20 to slide is arranged on the glue delivery shaft 10. When the glue coating roller 41 rotates, before the glue extrusion port 411 contacts the PE film, the driving member drives the glue extrusion plate 20 of the glue extrusion port 411 to slide inwards, and at this time, the glue extrusion port 411 is open, and the glue liquid in the glue coating roller 41 will converge to the glue extrusion port 411, and in the process of the rotation of the glue coating roller 41, due to the action of centrifugal force, the glue liquid will be given a force to converge to the glue extrusion port 411, thereby ensuring that the glue extrusion port 411 is full of glue liquid, and when the glue extrusion port 411 is facing downward, the driving member drives the glue extrusion plate 20 to slide outwards, and the glue extrusion plate 20 squeezes the glue liquid out of the glue extrusion port 411 and squeezes it onto the surface of the PE film, thereby realizing the gluing operation. Since the glue extrusion ports 411 are distributed at intervals, the glue on the PE film is also distributed at intervals, and then under the action of the scraper 42, the glue can be distributed continuously and evenly on the PE film.

[0050] Reference Figure 8 and Fig. 9 The driving member is configured as a driving wheel 30, which is coaxially fixed on the rubber delivery shaft 10. A concave wheel portion 301 is provided on the driving wheel 30, and the concave wheel portion 301 is located on a side close to the unwinding end of the PE film. A sliding sleeve 40 is installed in the glue coating roller 41. The number of the sliding sleeves 40 is the same as the number of the rubber extrusion plates 20 and corresponds one to one. The rubber extrusion plates 20 slide in the sliding sleeve 40. Sliding grooves 401 are provided on both side walls of the sliding sleeve 40. Sliding blocks 201 are formed on both sides of the rubber extrusion plates 20. The sliding blocks 201 slide in the corresponding sliding grooves 401. The sliding sleeve 40 is located in the sliding groove 401 and is installed with an abutting spring 402. One end of the abutting spring 402 is connected to the sliding block 201, and the other end of the abutting spring 402 is connected to the inner wall of the sliding groove 401. The rubber squeezing plate 20 is also fixedly connected with a connecting rod 202 , which is located on a side close to the rubber delivery shaft 10 . The connecting rod 202 passes through the sliding sleeve 40 , and the end of the connecting rod 202 is rotatably connected with an abutment wheel 203 , which is always in abutment with the driving wheel 30 .

[0051] The glue roller 41 rotates, the glue delivery shaft 10 does not rotate, and the abutting wheel 203 rotates around the driving wheel 30. When the abutting wheel 203 moves to the concave wheel portion 301, under the action of the abutting spring 402, the sliding block 201 drives the glue extruding plate 20 to slide inward. When the abutting wheel 203 is separated from the concave wheel portion 301, the glue extruding plate 20 is reset, that is, it slides outward to achieve the glue extrusion action. The abutting spring 402 can be protected by the cooperation of the sliding sleeve 40 and the glue extruding plate 20. In practice, the glue liquid will be heated in advance and then passed into the glue roller 41. At this time, the glue liquid has strong fluidity. The closer the glue liquid is to the glue delivery shaft 10, the higher the temperature of the glue liquid is. The glue liquid squeezed onto the PE film is the glue liquid on the outer peripheral side of the glue roller 41, which has a relatively low temperature and is not very fluid.

[0052] Reference Figure 6 A floating wheel 93 is coaxially fixed to the rotating shaft 9, and a plurality of cam portions 931 are arranged in a circular array on the floating wheel 93. The number of the cam portions 931 is the same as the number of the glue extrusion ports 411 and corresponds one to one. A supporting wheel 143 is rotatably connected to the fixed plate 14, and the supporting wheel 143 is always in contact with the floating wheel 93.

[0053] When the cam portion 931 on the floating wheel 93 contacts the supporting wheel 143, the floating wheel 93 will drive the glue coating roller 41 to move upward. When the cam portion 931 is separated from the supporting wheel 143, the floating wheel 93 will reset. When the glue coating roller 41 moves upward, the glue extrusion port 411 is just facing downward, that is, the glue extrusion operation is performed at this time; if the glue coating roller 41 is always in contact with the PE film, then when the glue extrusion plate 20 slides to squeeze glue, part of the glue will flow back into the glue coating roller 41, resulting in a small amount of glue output, and there will be glue adhering to the surface of the glue coating roller 41, affecting the glue coating effect. In this application, the glue can be recovered by scraping glue later. Therefore, during the glue coating process, even if the amount of glue applied is large, there will be no waste of glue; therefore, when the glue extrusion port 411 faces downward and glue is squeezed onto the PE film, the glue coating roller 41 rises, and a certain space is generated between it and the PE film, so that the glue application amount can be guaranteed.

[0054] Reference Figure 2 and Fig.10 The extrusion composite mechanism 5 includes a lower pressing roller 51 and an upper pressing roller 52. Two vertical mounting plates 50 are symmetrically installed on the machine body 1. The lower pressing roller 51 is rotatably connected to the mounting plate 50. The upper pressing roller 52 is lifted and lowered on the upper side of the lower pressing roller 51. A sliding groove 501 is opened on the mounting plate 50 in the vertical direction. The mounting plate 50 is slidably connected with a sliding block 502 in the sliding groove 501. Both ends of the upper pressing roller 52 are rotatably connected with the two sliding blocks 502. The mounting plate 50 is also slidably connected with a connecting block 503 in the sliding groove 401. The sliding block 502 and the connecting block 503 are connected by a compression spring 504. A driving cylinder 60 is installed on the mounting plate 50. The driving cylinder 60 is vertically arranged downward, and the piston rod end of the driving cylinder 60 is fixedly connected to the connecting block 503.

[0055] The glass fiber cloth and the two PE films are extruded and compounded between the upper pressure roller 52 and the lower pressure roller 51. The cylinder 60 is driven to drive the connecting block 503 to descend. When the connecting block 503 descends, the compression spring 504 is compressed, that is, the force acting on the sliding block 502 changes, so that the extrusion force of the lower pressure roller 51 changes, that is, the adjustment of the extrusion force is achieved.

[0056] The implementation principle of a glass fiber cloth composite coating machine in an embodiment of the present application is as follows: the glass fiber cloth and two PE films are unwound synchronously, and the glass fiber cloth is transported to the extrusion composite mechanism 5 after unwinding. After the PE film is unwound, it is glued by the gluing mechanism 4, and then transported to the extrusion composite mechanism 5. The three are extruded and composited at the extrusion composite mechanism 5, and finally rolled up; in the gluing process, the gluing roller 41 squeezes the glue liquid onto the PE film, and then the scraper plate 42 scrapes the glue liquid on the PE film evenly, and the excess accumulated glue liquid will gradually fall from the glue inlet 422 along the inclined scraper portion 421 onto the conveyor belt 71, and then during the conveying process of the conveyor belt 71, the scraper plate 81 scrapes the glue liquid on the conveyor belt 71 and collects it in the glue box 8, and the glue liquid is collected and then reused.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
