Description

Technical Field

[0001] The invention relates to the field of self-adhesive film waterproof coiled materials, and in particular to an automatic coating device and process for producing the self-adhesive film waterproof coiled materials. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to prevent external rainwater and groundwater leakage. As a leak-proof connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. Waterproof membrane can be mainly divided into asphalt waterproof membrane and polymer waterproof membrane according to its material and use purpose. Among them, polymer self-adhesive film waterproof membrane, as an optimized version of polymer waterproof membrane, is composed of polymer sheet (PVC, PE, EVA, ECB, TPO, etc.), self-adhesive rubber asphalt adhesive, granular anti-sticking layer and isolation film, and can be reinforced with composite fabric on the polymer sheet as needed. This membrane combines the advantages of polymer waterproof membrane and self-adhesive membrane, greatly improving the puncture resistance, weather resistance, self-healing, high and low temperature resistance and other properties, with better physical properties and more stable chemical properties.

[0003] During the production and processing of polymer self-adhesive waterproof membranes, the hot-melt adhesive must be melted in advance and then applied to the surface of the polymer sheet. The particle anti-sticking layer and the isolation film are then attached and fixed. During the process of applying glue and coating on the surface of the polymer sheet, the following problems often occur:

[0004] (1) When the glue coating adheres to the surface of the polymer sheet after heating, the traditional continuous polymer sheet conveying method makes it difficult for the glue to maintain its appropriate self-flow ability during the adhesion process, and it is difficult to quickly and adaptively fill the blank areas of the polymer sheet surface, thereby reducing the effective coating adhesion area of ​​the glue;

[0005] (2) During the coating and transportation process of polymer sheets, it is difficult to actively oscillate and eliminate the trace bubbles generated by heating the glue, which reduces the uniformity of the glue coating adhesion thickness. It is also difficult to clean and wipe the redundant residual glue generated during the transportation of polymer sheets, which increases the workload of subsequent cleaning and maintenance operations.

[0018] In addition, the present invention also provides a production process of an automatic coating device for producing self-adhesive film waterproof coiled materials, comprising the following steps:

[0019] S1. Operation inspection: First, the staff connects the glue coating seat with the existing self-adhesive water storage tank through the glue delivery pipeline, and tests the glue output of the glue outlet at the bottom of the glue coating seat to ensure that the glue output of multiple glue outlets is uniform. Then, temporarily close the glue outlet and maintain a constant temperature. After that, make the pushing mechanism in the initial position at the front of the base frame, start the warm air pipe in the middle of the defoaming chamber for intermittent work, and preheat the pushing mechanism through the warm air pipe. After that, the staff will pass the glue layer polymer sheet in the waterproof membrane along the gap between the pressing shafts. The soft wool layer arranged on the outer wall of the pressing shaft can prevent the surface of the polymer sheet from producing wrinkles or deformation that are difficult to recover through flexible contact during the process of pressing the polymer sheet. After that, the end of the polymer sheet is passed through the glue coating seat and the pushing mechanism in sequence until the end of the polymer sheet passes through the through slot of the guide bin. After the end of the polymer sheet passes through the guide bin, the staff will install the particle anti-sticking layer and the isolation film in the waterproof roll to the predetermined position, and use the existing laminating equipment to carry out the next step of laminating and pressing operation.

[0020] S2, glue conveying: after the polymer sheet is installed in place, the pushing mechanism is started to work forward, and the polymer sheet at the position just above the defoaming bin is clamped by the pushing mechanism, and the polymer sheet is pulled to move synchronously to the rear of the base frame. During the movement of the polymer sheet, the guide roller is started to operate to perform active conveying operation at the rear of the polymer sheet, and during the forward working of the pushing mechanism, the glue outlet at the bottom of the glue coating seat is started to work synchronously, and the glue is continuously sprayed onto the upper end surface of the polymer sheet through the glue outlet. Subsequently, the glue adhering to the upper surface of the polymer sheet moves synchronously with the polymer sheet. In the process of passing through the scraper, the glue is limited and blocked by the scraper. The glue within the reserved thickness immediately passes through the bottom of the scraper and moves continuously with the polymer sheet. A small amount of redundant glue is blocked by the front of the scraper and gradually flows to the two ends of the scraper, and after flowing to the end position of the scraper, it falls from the leakage grooves on both sides of the base frame 1 to the waste bin;

[0021] S3, Oscillation cooling: After the polymer sheet is coated with glue and forward conveyed, the bottom of the glue-coated area of ​​the polymer sheet is intermittently and continuously tapped by the pushing mechanism to further enhance the uniformity of the glue thickness attached to the upper end surface of the polymer sheet. At the same time, the rapid vibration can also cool the glue, slowing its flow ability, so that the glue's fluidity falls within the preset range required for subsequent lamination operations;

[0022] S4, laminating and collecting: During steps S2 and S3, the laminating operation among the polymer sheet, the isolation film and the particle anti-sticking layer in the waterproof roll is completed by the existing laminating equipment, and the waterproof roll is rolled up and stored after the laminating is completed.

[0023] Beneficial effects

[0024] 1. The automatic coating device and process for the production of self-adhesive film waterproof coiled materials described in the present invention are characterized by a soft fur layer arranged on the outer wall of the pressing shaft, which can flexibly press the polymer sheet. Through the flexible support of multiple staggered clamping rods and elastic pads, the effective clamping area of ​​the polymer sheet can be increased within a certain range. The flexible contact avoids the formation of difficult-to-recover wrinkles or deformation on the surface of the polymer sheet. In the subsequent conveying process, the inclined barrier effect of the scraper can improve the uniformity of glue adhesion on the surface of the polymer sheet.

[0025] 2. The automatic coating device and process for producing self-adhesive waterproof membranes described in the present invention, through the intermittent preheating effect of the warm air duct, while keeping the glue's own temperature and fluidity within the optimal range, causes the glue attached to the upper surface of the polymer sheet to produce torsional vibration within a certain degree of freedom through the blowing of airflow. The vibration can cause the upper surface of the glue on the polymer sheet to shake in multiple directions. Combined with the intermittent conveying operation of the waterproof membrane, it can facilitate the rapid adaptive filling of tiny bubbles or blank areas of the glue on the surface of the polymer sheet, thereby improving the uniformity of the glue thickness.

[0026] 3. The automatic coating device and process for producing self-adhesive film waterproof coil materials described in the present invention can intermittently wipe the contact points of the pushing mechanism with the glue through the active staggered replacement and wiping action of the wiping cloth during the conveying operation after the polymer sheet is coated with glue, thereby avoiding wrinkles or deflections of the polymer sheet caused by residual glue adhering to the contact points during the continuous conveying process, and also improving the linear alignment between the polymer sheet, the isolation film and the particle anti-sticking layer during the subsequent bonding operation, while reducing the workload of the subsequent cleaning and maintenance operations.

[0044] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an automatic coating device for the production of self-adhesive film waterproof coil, including a base frame 1, a pressing shaft 2, an extension plate 3, a gluing seat 4, a defoaming bin 5, a pushing mechanism 6, a gluing mechanism 7, a guide bin 8, a scraper 9, a waste bin 10 and a supporting foot 11, wherein the base frame 1 is a double-layer structure, the lower end of the base frame 1 is evenly equipped with supporting feet 11, the upper front end of the base frame 1 is symmetrically equipped with a pressing shaft 2 by rotating cooperation, the outer wall of the pressing shaft 2 is provided with a soft fur layer 21, and the upper and lower two pressing shafts 2 soft fur layers 21 The gap between the outer contours is slightly smaller than the thickness of the waterproof membrane. An extension plate 3 is fixedly installed on the front of the upper end of the base frame 1. A glue coating seat 4 is fixedly installed on the front of the extension plate 3. The glue coating seat 4 is located above the base frame 1 and the glue coating seat 4 is located behind the pressing shaft 2. The lower end of the glue coating seat 4 is evenly installed with glue outlets, and the glue outlets are connected to the existing glue box through the glue coating seat 4. A scraper plate 9 is fixedly installed on the lower end face of the front of the extension plate 3. The scraper plate 9 is tilted and the bottom of the scraper plate 9 is tilted toward the middle position of the base frame 1. , a glue erasing mechanism 7 is installed in the middle of the extension plate 3, a leakage groove is symmetrically provided on the left and right sides of the front upper end of the base frame 1, and the leakage groove is respectively located at the end positions of the scraper plate 9, a waste bin 10 is symmetrically installed on the left and right sides of the front of the base frame 1, and the waste bin 10 is connected to the leakage groove, a defoaming bin 5 is fixedly installed on the front upper end of the base frame 1, a warm air pipe 51 is fixedly installed in the middle of the defoaming bin 5, and an air outlet is evenly provided on the upper end of the warm air pipe 51, and the position height of the air outlet is lower than the position height of the upper end surface of the base frame 1, the base frame 1 A pushing mechanism 6 is movably installed in the middle of the upper end, and the pushing mechanism 6 is located above the defoaming bin 5. A guide bin 8 is fixedly installed at the rear upper end of the base frame 1. A through slot is provided in the middle of the guide bin 8. A guide roller 81 is evenly installed on the bottom of the through slot by rotating cooperation. The guide roller 81 is a prior art means, and the upper end position height of the guide roller 81 is equal to the height of the upper end surface position of the base frame 1. An air nozzle 82 is evenly provided on the top of the through slot, and the air nozzle 82 faces the upper end surface position of the base frame 1.

[0045] During the specific work, the staff first connects the glue coating seat 4 with the existing self-adhesive water storage tank through the glue delivery pipeline, and tests the glue output of the glue outlet at the bottom of the glue coating seat 4, so that the glue output of multiple glue outlets arranged evenly remains uniform. Then, the glue outlet is temporarily closed and a constant temperature state is maintained. After that, the pushing mechanism 6 is placed in the initial position at the front of the base frame 1, and the warm air pipe 51 in the middle of the defoaming bin 5 is started for intermittent work. The pushing mechanism 6 is preheated through the warm air pipe 51. After that, the staff inserts the glue-coated polymer sheet 00 in the waterproof coil along the gap between the pressing shafts 2. The soft hair layer 21 arranged on the outer wall of the pressing shaft 2 can avoid the formation of wrinkles or cracks on the surface of the polymer sheet 00 that are difficult to recover through flexible contact during the process of pressing the polymer sheet 00. After deformation, the end of the polymer sheet 00 is passed through the glue coating seat 4 and the pushing mechanism 6 in sequence until the end of the polymer sheet 00 passes through the through slot of the guide bin 8. At this time, the bottom of the polymer sheet 00 is against the guide roller 81. Subsequently, the air is continuously delivered to the air nozzle 82 through the existing air pump. After the air flow flows out of the air nozzle 82, it is blown vertically to the upper end surface of the polymer sheet 00, increasing the contact pressure between the polymer sheet 00 and the guide roller 81, and realizing the compaction of the polymer sheet 00 in a contactless manner within the preset pressure range. After the end of the polymer sheet 00 passes through the guide bin 8, the staff installs the granular anti-sticking layer and the isolation film in the waterproof membrane to the predetermined position, and performs the next step of bonding and compacting operation through the existing bonding equipment.

[0046] See Figure 4 、 Figure 5 、 Figure 7 and Figure 11 The pushing mechanism 6 includes a shift slide 61, an alignment magnet 62, a pushing slide rod 63, meshing teeth 64, a pushing shaft 65, a pushing gear 66 and a pushing motor 67. The shift slide 61 is installed on the middle part of the upper end of the base frame 1 by a sliding fit. The front end of the shift slide 61 and the front part of the base frame 1 are symmetrically provided with alignment magnets 62 that attract each other. The two end portions of the guide magazine 8 are both installed with a pushing slide rod 63 by a sliding fit, and the ends of the two pushing slide rods 63 are respectively slidably connected to the two ends of the shift slide 61. The rear part of the upper end of the base frame 1 is provided with a pushing shaft 65 through a bearing. Both ends of the pushing shaft 65 are provided with a pushing gear 66 by a key connection. The lower end of the pushing slide rod 63 is evenly provided with meshing teeth 64, and the meshing teeth 64 are meshed with the pushing gear 66 for transmission. The rear part of the base frame 1 is fixedly provided with a pushing motor 67 through a motor seat, and the output shaft of the pushing motor 67 is connected to the pushing shaft 65 through a coupling.

[0047] In specific operation, after the polymer sheet 00 is installed in place, the pushing motor 67 is started to run forward, and the pushing shaft 65 is driven to rotate by the pushing motor 67, and the pushing gear 66 is driven to rotate by the pushing shaft 65, and the pushing slide 63 is driven to slide in the horizontal direction through the meshing transmission between the pushing gear 66 and the meshing teeth 64. The magnetic attraction between the positioning magnets 62 is overcome by the pulling of the pushing slide 63, and the shift slide 61 is made to slide on the base frame 1, and in the process of the shift slide 61 moving from the front to the rear of the base frame 1, the high pressure at the position just above the defoaming bin 5 is moved. The polymer sheet 00 is clamped and pulled to move synchronously to the rear of the base frame 1. During the movement of the polymer sheet 00, the guide roller 81 is started to operate to actively convey the rear of the polymer sheet 00. In the process of the forward operation of the push motor 67, the glue outlet at the bottom of the glue coating seat 4 is synchronously started to work, and the glue is continuously sprayed to the upper end surface of the polymer sheet 00 through the glue outlet. Subsequently, the glue adhering to the upper surface of the polymer sheet 00 moves synchronously with the polymer sheet 00. In the process of the glue passing through the scraper 9, it is limited and blocked by the scraper 9. The glue within the reserved thickness then passes through the bottom of the scraper plate 9 and moves continuously with the polymer sheet 00. A small amount of redundant glue gradually flows to the two ends of the scraper plate 9 after being blocked by the front of the scraper plate 9. After flowing to the end position of the scraper plate 9, it falls from the leakage grooves on both sides of the base frame 1 to the waste bin 10. When the shift slide 61 drives the polymer sheet 00 to move, the shift slide 61 moves out of the upper position of the defoaming bin 5. The glue attached to the upper surface of the polymer sheet 00 is blown by the intermittent airflow of the warm air pipe 51 in the process of passing through the position of the defoaming bin 5. Its own temperature remains stable, and its own flow capacity is also within the optimal range. Under the intermittent blowing action of the airflow, the polymer sheet 00 above the defoaming chamber 5 produces a slight vibration, which further causes the glue attached to the upper surface of the polymer sheet 00 to produce torsional vibration within a certain degree of freedom. The vibration can cause the upper surface of the glue on the surface of the polymer sheet 00 to shake in multiple directions. When there are tiny bubbles or blank areas of glue on the upper surface of the polymer sheet 00, the active oscillation and shaking action of the glue can adaptively fill them, while keeping the thickness of the glue in various areas on the upper surface of the polymer sheet 00 uniform.

[0048] See Figures 5 to 11The middle part of the shift slide 61 is fixedly installed with a support plate 611, and the warm air pipe 51 is located below the support plate 611. The upper end surface of the support plate 611 is fixedly installed with an elastic pad 6111. The material of the elastic pad 6111 can be rubber, silicone or sponge, and the upper end surface height of the elastic pad 6111 is slightly lower than the upper end surface position height of the base frame 1. The middle part of the shift slide 61 is symmetrically installed with a shift shaft 612 by rotating cooperation. The shift shaft 612 is respectively located on the left and right sides of the elastic pad 6111. The upper end of the shift shaft 612 is at the same height as the upper end of the base frame 1. A vertical rod 613 is symmetrically installed on the middle of the shift slide 61. The upper end of the vertical rod 613 is jointly installed with a clamping frame 6131 by sliding cooperation. The clamping frame 6131 is located above the base frame 1 and the clamping frame 6131 is connected to the shift slide 61 through a clamping spring 6132. The end of the push slide 63 is fixedly installed with a connecting rope 631, and the other end of the connecting rope 631 is fixedly connected to the clamping frame 6131. On the holding frame 6131, the middle of the left and right ends of the shift slide 61 are fixedly installed with a bogie 614, the middle of the connecting rope 631 slides against the side wall of the bogie 614, and the connecting rope 631 is bent into an L shape under the action of the spacing of the bogie 614. The front half of the connecting rope 631 is parallel to the vertical rod 613, and the rear half of the connecting rope 631 is parallel to the pushing slide 63. The clamping frame 6131 and the shift slide 61 are symmetrically provided with mutually adsorbed clamping magnets 615, and the two ends of the guide bin 8 are connected. The staggered rods 83 are fixedly connected to the parts, the ends of the staggered rods 83 are tapered inclined surface structures and the ends of the staggered rods 83 are located above the bogie 614, and the clamping rods 6133 are evenly installed on the lower bottom surface of the clamping frame 6131. ​​The lower ends of the clamping rods 6133 are arc structures and the two adjacent clamping rods 6133 are staggered with each other front and back on the clamping frame 6131. ​​The clamping rods 6133 are all located above the support plate 611 and the maximum span distance between the clamping rods 6133 is less than the width of the elastic pad 6111.

[0049] During specific operation, at the initial stage when the push motor 67 is running in the forward direction and the push slide 63 is moving in the horizontal direction, the magnetic attraction between the alignment magnets 62 is relatively strong. At this time, the shift slide 61 is still attached to the front position of the base frame 1, and the push slide 63 and the shift slide 61 produce relative sliding displacement. In the process of the push slide 63 moving and gradually moving away from the shift slide 61, the end of the push slide 63 pulls the connecting rope 631 to move synchronously. The connecting rope 631 is turned against the steering frame 614. After the action, the clamping frame 6131 is further pulled to slide downward on the vertical rod 613, and the clamping spring 6132 is gradually compressed during the sliding process, and the downward movement of the clamping frame 6131 can drive the clamping rod 6133 to move downward synchronously. When the clamping rod 6133 moves down to a predetermined height position, the arc surface of its lower end contacts the upper end surface of the polymer sheet 00, and then the clamping rod 6133 continues to move downward, and in the process of moving, the contact of the polymer sheet 00 is made by the abutment effect. When the amount of depression of the polymer sheet 00 reaches a predetermined range, the lower surface of the polymer sheet 00 is synchronously in contact with the elastic pad 6111 above the support plate 611, and at this time, the clamping magnets 615 at both ends of the clamping frame 6131 and the clamping magnets 615 at both ends of the shift slide 61 are attached to each other. At this time, under the adsorption effect of the clamping magnets 615, the clamping frame 6131 and the shift slide 61 form a whole, and the position of the connecting rope 631 is also relatively fixed. Afterwards, under the further pulling action of the push slide 63, the magnetic attraction between the alignment magnets 62 is overcome, so that the shift slide 61 and the clamping frame 6131 move as a whole, and the clamping movement of the polymer sheet 00 is realized during the overall movement. Through the flexible support of the multiple clamping rods 6133 arranged in a staggered manner and the elastic pad 6111, the effective clamping area of ​​the polymer sheet 00 can be increased within a certain range, and the synchronization degree of each area of ​​the polymer sheet 00 during the subsequent pulling movement is improved;

[0050] When the shift slide 61 drives the polymer sheet 00 to the predetermined position in front of the guide bin 8, the operation of the push motor 67 is stopped. Afterwards, under the action of inertia and the active conveying action of the guide roller 81, the shift slide 61 and the push slide rod 63 are relatively displaced again and continue to move a distance toward the guide bin 8. During the buffering displacement of the shift slide 61, the conical inclined surface at the end of the dislocation rod 83 is inserted into the position between the shift slide 61 and the clamping frame 6131 along the top of the bogie 614. The shift slide 61 is decelerated, and then, under the blocking action of the dislocation rod 83, the clamping frame 6131 begins to overcome the magnetic attraction of the clamping magnet 615 and moves upward along the vertical rod 613. After that, the clamping frame 6131 releases the pressing effect on the polymer sheet 00 and moves to the initial position above the vertical rod 613 under the elastic force of the clamping spring 6132. At this time, the shift slide 61 stops moving synchronously, and then controls the push motor 67 to move in the reverse direction. The push slide 63 is rotated, and the meshing transmission between the pushing gear 66 and the meshing teeth 64 is further used to make the pushing slide 63 displace and slide in the opposite direction. After that, the shift slide 61 is pushed by the pushing slide 63 to perform the reverse reset movement, and in this process, the clamping frame 6131 is always in the initial position, and the shift shaft 612 set in the middle of the shift slide 61 can be in rolling contact with the lower end surface of the polymer sheet 00 during the reset movement, reducing the friction between the polymer sheet 00 and the polymer sheet 00. In this process, the polymer sheet 00 is in a stationary state, and the work of the glue coating seat 4 is stopped during the reverse movement of the shift slide 61. When the shift slide 61 moves to the initial position in front of the base frame 1, the positioning magnet 62 works again and completes the locking of the position of the shift slide 61. At this time, the shift slide 61 is again located above the warm air pipe 51, and the shift slide 61 is preheated by the work of the warm air pipe 51. This reciprocating process realizes the intermittent gluing and conveying operation of the polymer sheet 00.

[0051] See Figure 5 、 Figure 9 、 Figure 11 and Figure 13 The rear part of the shift slide 61 is equipped with a vibration shaft 616 through a bearing. The two end portions of the vibration shaft 616 are connected to the shift slide 61 through a torsion spring 6161. The middle part of the vibration shaft 616 is evenly equipped with a vibration frame 6162 along its axial direction. The vibration frame 6162 is tilted, and the inclined upper end of the vibration frame 6162 is evenly equipped with an elastic rod 6163. The material of the elastic rod 6163 can be rubber, silicone or foam, and the upper end position height of the elastic rod 6163 is less than the upper end surface position height of the base frame 1. The middle part of the base frame 1 is evenly equipped with a vibration protrusion 12. The vibration protrusion 12 is a semi-teardrop-shaped structure, and the teardrop-shaped tip position of the vibration protrusion 12 is facing the front of the base frame 1. The inclined lower end of the vibration frame 6162 is pressed against the vibration protrusion 12 by sliding fit.

[0052] During specific operation, when the shift slide 61 moves from the front of the base frame 1 to the rear of the base frame 1, the vibration frame 6162 is abutted by the teardrop-shaped front end of the vibration protrusion 12. In the process of following the horizontal movement of the shift slide 61, it synchronously performs intermittent positive rotation around the axis of the vibration shaft 616 as the center. Since the vibration frame 6162 is tilted, the positive rotation direction of the vibration frame 6162 at this time is tilted downward. The elastic rod 6163 set at the upper end of the vibration frame 6162 gradually moves away from the lower end surface of the polymer sheet 00 during the positive rotation. In the process of the shift slide 61 returning to the front of the base frame 1 from the rear of the base frame 1, the vibration frame 6162 is abutted by the teardrop-shaped rear end of the vibration protrusion 12, which further causes the vibration frame 6162 to perform intermittent rotation in the opposite direction. At this time, the elastic rod 6163 set at the upper end of the vibration frame 6162 During the reverse rotation, the elastic rod 6163 gradually approaches the lower end surface of the polymer sheet 00, and contacts the lower end surface of the polymer sheet 00 after rotating through a predetermined angle, and through the beating action, the contact part of the polymer sheet 00 is bent with a certain degree of freedom, further enhancing the uniformity of the thickness of the glue attached to the upper end surface of the polymer sheet 00. At the same time, the glue can be cooled down and its flow ability can be delayed through the rapid vibration action, so that the fluidity of the glue enters the preset range required for the subsequent bonding operation. The evenly arranged vibration protrusions 12 can prompt the vibration frame 6162 to continuously and completely beat the polymer sheet 00 located between the guide bin 8 and the defoaming bin 5, and the active conveying operation of the guide roller 81 can be coordinated with the intermittent beating of the elastic rod 6163, so that the polymer sheet 00 is horizontally reset in the intervals between the beatings.

[0053] See Figures 7 to 12, the wiping mechanism 7 includes a fixed frame 71, a wiping slide bar 72, a wiping slide bar 73, a conveying roller 74, a wiping cloth 75 and a wiping cylinder 76. The fixed frame 71 is symmetrically installed at the middle of the left and right sides of the extension plate 3. The wiping slide bar 72 is fixedly installed on the fixed frame 71. The wiping slide bar 72 and the fixed frame 71 are jointly installed with the wiping slide bar 73 by sliding cooperation. The conveying roller 74 is installed in the wiping slide bar 73 by rotating cooperation. The conveying roller 74 is a conventional technical means, and the wiping cloth 75 is jointly sleeved between the conveying rollers 74 on the left and right sides of the extension plate 3. The wiping cloth 75 is located below the clamping rod 6133. The wiping cylinder 76 is fixedly installed on the extension plate 3, and the output shaft of the wiping cylinder 76 is connected to the wiping slide bar 73. The rear part of the fixed frame 71 is provided with a boss with gradually increasing thickness. The thickness of the boss is greater than the straight-line distance between the rubber cloth 75 and the lower end of the clamping rod 6133. The upper end surface of the boss is evenly installed with a cross bar 711. The end of the rubber slide 73 is symmetrically provided with a give-way slide groove 731. The give-way slide groove 731 is jointly installed with a give-way rod 732 by a sliding fit. The give-way rod 732 is connected to the rubber slide 73 by a give-way spring 733. The central axis of the give-way rod 732 is parallel to the central axis of the conveying roller 74, and the rubber cloth 75 passes through the middle of the give-way rod 732 by a sliding fit. The lower end of the give-way rod 732 is fixedly installed with a toggle rod 734, and the lower end of the toggle rod 734 is against the upper end surface of the fixed frame 71 by a sliding fit.

[0054] When the shift slide 61 and the clamping frame 6131 are reset, the eraser cylinder 76 is started to work, and the eraser slide 73 is pushed on the eraser slide rod 72 to move toward the clamping frame 6131 through the eraser cylinder 76. The conveying roller 74 and the yield rod 732 are driven to move synchronously through the eraser slide 73, and the eraser cloth 75 is driven to move synchronously through the conveying roller 74. When the yield rod 732 moves to the boss position of the fixed frame 71, the toggle rod 734 is lifted by the tilt of the boss and begins to move upward. The rubbing tape 75 is moved upward synchronously by the action of the limiting mechanism, and the rubbing tape 75 moves upwardly in the direction of the clamping frame 6131 along an inclined upward movement path as a whole. After moving to a predetermined position, the rubbing tape 75 contacts the arc surface at the lower end of the clamping rod 6133 and completes the wiping and cleaning operation of the residual glue on the end of the clamping rod 6133. As the toggle rod 734 moves further, its bottom contacts the cross bar 711. The intermittent lifting action of the cross bar 711 can make the toggle rod 734 vibrate intermittently, and the limiting action of the yielding rod 732 can make the wiping cloth 75 vibrate intermittently during the wiping process, further improving the cleaning effect of the residual glue at the end of the clamping rod 6133. After the cleaning and wiping operation is completed, the wiping slide 73 is reset by the wiping cylinder 76, further restoring the conveying roller 74, and in the process of resetting the conveying roller 74 , start the conveying roller 74 to operate, and the wiping cloth 75 is rolled up when the conveying roller 74 rotates, so that the area of ​​the wiping cloth 75 with residual glue is misaligned with the clamping rod 6133. After that, stop the operation of the conveying roller 74, and the lower end of the clamping rod 6133 set through the arc surface can reduce the amount of residual glue after each clamping and conveying operation. The active winding and misalignment of the wiping cloth 75 can make the wiping area on the clean cloth surface each time, further improving the cleanliness of the wiping operation and reducing the workload of the subsequent cleaning and maintenance operations.

[0055] In addition, the present invention also provides a production process of an automatic coating device for producing self-adhesive film waterproof coiled materials, comprising the following steps:

[0056] S1. Operation inspection: First, the staff connects the glue coating seat 4 with the existing self-adhesive water storage tank through the glue delivery pipeline, and tests the glue output of the glue outlet at the bottom of the glue coating seat 4 to ensure that the glue output of multiple glue outlets arranged evenly remains uniform. Then, the glue outlet is temporarily closed and a constant temperature is maintained. After that, the pushing mechanism 6 is in the initial position at the front of the base frame 1, and the warm air pipe 51 in the middle of the defoaming bin 5 is started for intermittent work. The pushing mechanism 6 is preheated through the warm air pipe 51. After that, the staff inserts the glue-coated polymer sheet 00 in the waterproof coil along the gap between the pressing shafts 2. The soft hair layer 21 arranged on the outer wall of the pressing shaft 2 can avoid the surface of the polymer sheet 00 from being compressed by flexible contact during the process of pressing the polymer sheet 00. After the surface produces wrinkles or deformations that are difficult to recover, the end of the polymer sheet 00 is passed through the glue coating seat 4 and the pushing mechanism 6 in sequence until the end of the polymer sheet 00 passes through the through slot of the guide bin 8. At this time, the bottom of the polymer sheet 00 is against the guide roller 81. Subsequently, the existing air pump is used to continuously deliver air to the air nozzle 82. After the air flow flows out of the air nozzle 82, it is blown vertically to the upper end face of the polymer sheet 00, increasing the contact pressure between the polymer sheet 00 and the guide roller 81, and achieving contactless compression of the polymer sheet 00 within the preset pressure range. After the end of the polymer sheet 00 passes through the guide bin 8, the staff installs the particle anti-sticking layer and the isolation film in the waterproof membrane to the predetermined position.

[0057] S2. Glue coating and conveying: After the polymer sheet 00 is installed in place, the push motor 67 is started to run forward, and the push shaft 65 is driven to rotate by the push motor 67, and the push gear 66 is driven to rotate by the push shaft 65. The push slide 63 is further driven to slide in the horizontal direction through the meshing transmission between the push gear 66 and the meshing teeth 64. In the initial stage when the push motor 67 runs forward and causes the push slide 63 to move in the horizontal direction, the magnetic attraction between the alignment magnets 62 is strong. At this time, The shift slide 61 is still attached to the front position of the base frame 1, and the push slide 63 and the shift slide 61 produce relative sliding displacement, and in the process of the push slide 63 moving and gradually moving away from the shift slide 61, the end of the push slide 63 pulls the connecting rope 631 to move synchronously, and the connecting rope 631 further pulls the clamping frame 6131 to slide downward on the vertical rod 613 after the abutment and steering action of the steering frame 614, and in the process of sliding, the clamping spring 6132 is gradually compressed, and through the clamping frame 6131 The downward movement of the clamping rod 6133 can drive the clamping rod 6133 to move downward synchronously. When the clamping rod 6133 moves down to a predetermined height, the arc surface of its lower end contacts the upper end surface of the polymer sheet 00. Subsequently, the clamping rod 6133 continues to move downward, and in the process of movement, the contact part of the polymer sheet 00 is slightly depressed by the abutment effect. When the depression amount of the polymer sheet 00 reaches a predetermined range, the lower bottom surface of the polymer sheet 00 is synchronously contacted with the elastic pad 6111 above the support plate 611, and at this time the clamping frame 6133 is in contact with the elastic pad 6111 above the support plate 611. The clamping magnets 615 at both ends of the shifting carriage 61 are attached to and attracted by each other. At this time, under the adsorption action of the clamping magnets 615, the clamping frame 6131 and the shifting carriage 61 form a whole, and the position of the connecting rope 631 is relatively fixed. Thereafter, under the further pulling action of the push slide 63, the magnetic attraction between the alignment magnets 62 is overcome, and the shifting carriage 61 and the clamping frame 6131 move as a whole. During the overall movement, the polymer sheet 00 is clamped and moved.

[0058] During the movement of the polymer sheet 00, the guide roller 81 is started to operate, and the rear part of the polymer sheet 00 is actively conveyed, and during the forward operation of the push motor 67, the glue outlet at the bottom of the glue coating seat 4 is synchronously started to work, and the glue spraying operation is continuously performed to the upper end surface of the polymer sheet 00 through the glue outlet. Subsequently, the glue adhering to the upper surface of the polymer sheet 00 moves synchronously with the polymer sheet 00. In the process of passing through the scraper 9, the glue is limited and blocked by the scraper 9. The glue within the reserved thickness immediately passes through the bottom of the scraper 9 and moves continuously with the polymer sheet 00. A small amount of redundant glue gradually flows to the two ends of the scraper 9 after being blocked by the front of the scraper 9, and after flowing to the end position of the scraper 9, it falls from the leakage grooves on both sides of the base frame 1 to the waste bin 10, and when the shift slide 61 drives the polymer sheet 00 to move, the glue is continuously sprayed to the upper end surface of the polymer sheet 00. During the movement of the polymer sheet 00, the shift slide 61 moves out of the upper position of the defoaming chamber 5, and the glue attached to the upper surface of the polymer sheet 00 is subjected to the intermittent airflow blowing of the warm air pipe 51 during the process of passing through the position of the defoaming chamber 5. The temperature of the glue itself remains stable, and its own flowability is also within the optimal range. Under the intermittent blowing of the airflow, the polymer sheet 00 above the defoaming chamber 5 generates a slight vibration, which further causes the glue attached to the upper surface of the polymer sheet 00 to generate a torsional vibration within a certain degree of freedom. The vibration can cause the upper surface of the glue on the surface of the polymer sheet 00 to shake in multiple directions. When there are tiny bubbles or blank areas of glue on the upper surface of the polymer sheet 00, they can be adaptively filled through the active oscillation and shaking of the glue, and at the same time, the thickness of the glue in each area on the upper surface of the polymer sheet 00 is kept uniform.

[0059] When the shift slide 61 drives the polymer sheet 00 to the predetermined position in front of the guide bin 8, the operation of the push motor 67 is stopped. Afterwards, under the action of inertia and the active conveying action of the guide roller 81, the shift slide 61 and the push slide rod 63 are relatively displaced again and continue to move a distance toward the guide bin 8. During the buffering displacement of the shift slide 61, the conical inclined surface at the end of the dislocation rod 83 is inserted into the position between the shift slide 61 and the clamping frame 6131 along the top of the bogie 614. The shift slide 61 is decelerated, and then, under the blocking action of the dislocation rod 83, the clamping frame 6131 begins to overcome the magnetic attraction of the clamping magnet 615 and moves upward along the vertical rod 613. After that, the clamping frame 6131 releases the pressing effect on the polymer sheet 00 and moves to the initial position above the vertical rod 613 under the elastic force of the clamping spring 6132. At this time, the shift slide 61 stops moving synchronously, and then controls the push motor 67 to move in the reverse direction. The push slide 63 is rotated, and the meshing transmission between the pushing gear 66 and the meshing teeth 64 is further used to make the pushing slide 63 displace and slide in the opposite direction. After that, the shift slide 61 is pushed by the pushing slide 63 to perform the reverse reset movement, and in this process, the clamping frame 6131 is always in the initial position, and the shift shaft 612 set in the middle of the shift slide 61 can be in rolling contact with the lower end surface of the polymer sheet 00 during the reset movement, reducing the friction between the polymer sheet 00 and the polymer sheet 00. In this process, the polymer sheet 00 is in a stationary state, and the work of the glue coating seat 4 is stopped during the reverse movement of the shift slide 61. When the shift slide 61 moves to the initial position in front of the base frame 1, the positioning magnet 62 works again and completes the locking of the position of the shift slide 61. At this time, the shift slide 61 is again located above the warm air pipe 51, and the shift slide 61 is preheated by the work of the warm air pipe 51. This reciprocating process realizes the intermittent gluing and conveying operation of the polymer sheet 00.

[0060] S3, oscillation cooling: in the process of the shift slide 61 moving from the front of the base frame 1 to the rear of the base frame 1, the vibration frame 6162 is subjected to the abutment of the teardrop-shaped front end of the vibration protrusion 12, and in the process of following the horizontal movement of the shift slide 61, it synchronously performs intermittent positive rotation around the axis of the vibration shaft 616. Moreover, since the vibration frame 6162 is tilted, the positive rotation direction of the vibration frame 6162 at this time is tilted downward. The elastic rod 6163 provided at the upper end of the vibration frame 6162 gradually moves away from the lower end surface of the polymer sheet 00 during the positive rotation. In the process of the shift slide 61 returning to the front of the base frame 1 from the rear of the base frame 1, the vibration frame 6162 is subjected to the abutment of the teardrop-shaped front end of the vibration protrusion 12. The abutting effect of the teardrop-shaped rear end of the vibration protrusion 12 further causes the vibration frame 6162 to rotate intermittently in the opposite direction. At this time, the elastic rod 6163 arranged at the upper end of the vibration frame 6162 gradually approaches the lower end surface of the polymer sheet 00 during the reverse rotation, and contacts the lower end surface of the polymer sheet 00 after rotating through a predetermined angle. The contact part of the polymer sheet 00 is bent with a certain degree of freedom through the patting effect, further enhancing the uniformity of the thickness of the glue attached to the upper end surface of the polymer sheet 00. At the same time, the glue can be cooled by the rapid vibration effect, slowing down its flow ability, so that the fluidity of the glue enters the preset range required for the subsequent bonding operation.

[0061] S4, laminating and cleaning: after the shifting slide 61 and the clamping frame 6131 are reset, the eraser cylinder 76 is started to work, and the eraser slide 73 is pushed on the eraser slide rod 72 to move toward the clamping frame 6131 through the eraser cylinder 76, and the conveying roller 74 and the yield rod 732 are driven to move synchronously through the eraser slide 73, and the eraser cloth 75 is driven to move synchronously through the conveying roller 74. When the yield rod 732 moves to the boss position of the fixed frame 71, the toggle rod 734 is lifted by the tilt of the boss. The rubbing tape 75 is moved upward synchronously by the action of the lever 734, and the rubbing tape 75 moves upward synchronously. At this point, the rubbing tape 75 moves in an inclined upward direction toward the clamping frame 6131, and contacts the arc surface at the lower end of the clamping rod 6133 after moving to the predetermined position, completing the clamping of the clamping rod 6131. The wiping and cleaning operation of the residual glue at the end of the clamping rod 6133 is carried out, and in the process of further moving the toggle rod 734, its bottom contacts the cross bar 711, and the intermittent lifting effect of the cross bar 711 can make the toggle rod 734 vibrate intermittently, and further through the limiting effect of the yield rod 732, the wiping cloth 75 vibrates intermittently during the wiping process, further improving the cleaning effect of the residual glue at the end of the clamping rod 6133. After the cleaning and wiping operation is completed, the wiping slide 73 is reset by the wiping cylinder 76, and further The conveyor roller 74 is restored, and during the process of resetting the conveyor roller 74, the conveyor roller 74 is started to operate. The rubber tape 75 is rolled up by the rotation of the conveyor roller 74, so that the area of ​​the rubber tape 75 with residual glue is misaligned with the clamping rod 6133. After that, the operation of the conveyor roller 74 is stopped. In this process, the bonding operation between the polymer sheet 00, the isolation film and the particle anti-sticking layer in the waterproof roll is completed by the existing bonding equipment, and the waterproof roll is rolled up and stored after the bonding is completed.

8. A production process for an automatic coating device for producing self-adhesive film waterproofing coil, using the automatic coating device for producing self-adhesive film waterproofing coil according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1. Operation inspection: First, the staff connects the glue coating seat (4) with the existing self-adhesive water storage tank through the glue delivery pipeline, and tests the glue output of the glue outlet at the bottom of the glue coating seat (4) to ensure that the glue output of the multiple glue outlets is uniform. Then, the glue outlet is temporarily closed and the temperature is kept constant. After that, the pushing mechanism (6) is placed in the initial position at the front of the base frame (1), and the warm air pipe (51) in the middle of the defoaming chamber (5) is started to work intermittently. The pushing mechanism (6) is preheated through the warm air pipe (51). After that, the staff pushes the polymer sheet of the glue layer in the waterproof membrane along the pressing shaft (2). The soft fur layer (21) provided on the outer wall of the pressing shaft (2) can prevent the surface of the polymer sheet from producing wrinkles or deformations that are difficult to recover during the process of pressing the polymer sheet through flexible contact. After that, the end of the polymer sheet is passed through the glue coating seat (4) and the pushing mechanism (6) in sequence until the end of the polymer sheet passes through the through slot of the guide bin (8). After the end of the polymer sheet passes through the guide bin (8), the staff installs the particle anti-sticking layer and the isolation film in the waterproof roll to the predetermined position, and performs the next step of laminating and pressing operation through the existing laminating equipment. S2, glue conveying: After the polymer sheet is installed in place, the pushing mechanism (6) is started to work in the forward direction, and the polymer sheet at the position above the defoaming chamber (5) is clamped by the pushing mechanism (6), and the polymer sheet is pulled to move synchronously to the rear of the base frame (1). During the movement of the polymer sheet, the guide roller (81) is started to operate to carry out the active conveying operation of the rear of the polymer sheet, and during the forward working process of the pushing mechanism (6), the glue outlet at the bottom of the glue coating seat (4) is started to work synchronously, and the glue is discharged to the upper end surface of the polymer sheet through the glue outlet. Continuous glue spraying operation is performed, and then the glue adhering to the upper surface of the polymer sheet moves synchronously with the polymer sheet. In the process of passing through the scraper (9), the glue is subject to the limiting and blocking effect of the scraper (9). The glue within the reserved thickness then passes through the bottom of the scraper (9) and moves continuously with the polymer sheet. A small amount of redundant glue gradually flows to the two ends of the scraper (9) after being blocked by the front of the scraper (9). After flowing to the end position of the scraper (9), it falls from the leakage grooves on both sides of the base (1) to the waste bin (10); S3, oscillation cooling: After the polymer sheet is coated with glue and forwardly transported, the bottom of the glue-coated area of ​​the polymer sheet is intermittently and continuously patted by the pushing mechanism (6), further enhancing the uniformity of the thickness of the glue attached to the upper end surface of the polymer sheet. At the same time, the glue can be cooled by the rapid vibration, slowing down its flow ability, so that the fluidity of the glue enters the preset range required for the subsequent bonding operation; S4, laminating and cleaning: During the process of steps S2 and S3, the residual glue generated during the pushing process of the pushing mechanism (6) is cleaned by the glue wiping mechanism (7), and the laminating operation between the polymer sheet, the isolation film and the particle anti-sticking layer in the waterproof roll is completed by the existing laminating equipment. After the laminating is completed, the waterproof roll is rolled up and stored.
