Description

Technical Field

[0001] The present invention relates to the technical field of hot melt adhesive film preparation, and specifically to a preparation method for jelly glue pore glue hot melt adhesive film. Background Art

[0002] The main component of jelly glue is industrial gelatin, with water as the solvent. Its appearance is similar to jelly. As a raw material, the prepared hot melt adhesive film has the effects of high elasticity and breathability. The reason is that when producing the adhesive film, the plain roller is replaced with an uneven pattern roller. The cooperation of the grooves and convex surfaces enables the formed hot melt adhesive film to have pores, thereby achieving the effects of high elasticity and breathability.

[0003] In the existing preparation method of jelly glue pore glue hot melt adhesive film, when applying glue, the glue liquid is attached by an applicator roller and then rolled onto the pattern roller. However, for different pattern rollers, the depth dimensions of the surface grooves and convex surfaces are different. If the groove depth is relatively deep, it is easy for the glue liquid to not be completely filled into its interior during rolling, resulting in defects or unqualified final products. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a preparation method for jelly glue pore glue hot melt adhesive film, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A preparation method for jelly glue pore glue hot melt adhesive film, the preparation method for the jelly glue pore glue hot melt adhesive film includes the following steps:

[0006] Step 1: A glue delivery hose is connected to the top surface of the glue outlet press head. The glue liquid flows out from the bottom of the glue outlet press head and is injected into the coating box. The pattern roller body rotates while being attached to the coating box, so that the glue liquid adheres to the surface of the pattern roller body. The surface of the pattern roller body is designed with grooves and convex surfaces, and the grooves are used to accommodate the glue liquid;

[0007] Step 2: When the pattern roller body rotates, it drives the driving gear to rotate, thereby causing the transmission gear to rotate. The transmission gear rotates and drives the electric telescopic transmission rod, so that the glue outlet press head makes a lifting piston movement along the inside of the coating box, thereby continuously pressing down the glue liquid to fully fill the grooves on the surface of the pattern roller body with the glue liquid;

[0008] Step 3: As the pattern roller body rotates and passes by the blade body, the blade body scrapes off the glue liquid that is higher than the convex surface. Then, as the pattern roller body continues to rotate, the glue liquid in the grooves is carried out together with the release paper surface during transmission, thus completing the production of the porous hot melt adhesive film;

[0009] Step 4: While the driving gear rotates, it will also drive the force-bearing gear to make the reciprocating lead screw rotate. The reciprocating lead screw rotates to carry the moving seat sleeve, which drives the hollow scraper to slide back and forth along the outer wall of the pattern roller body and the glue applicator box. By the back-and-forth movement of the hollow scraper and in cooperation with the vision camera to detect whether there is glue liquid inside, it is judged whether there is glue leakage at the bottom side of the glue applicator box;

[0010] If glue leakage occurs, the electric telescopic drive rod is controlled to contract to adjust the pressing distance of the glue outlet press head, so as to reduce the pressure on the glue liquid inside the glue applicator box.

[0011] Further, the preparation method of the jelly glue hole hot melt adhesive film is applied with a pattern roller assembly. The pattern roller assembly includes a drive shaft, a pattern roller body, a glue applicator box, a driving gear, a transmission gear, an electric telescopic drive rod, a glue outlet press head, a force-bearing gear, a reciprocating lead screw, a moving seat sleeve and a hollow scraper. The surface of the drive shaft is fixed with the pattern roller body, and the glue applicator box is arranged on the top surface of the pattern roller body. The two ends of the drive shaft are sleeved with driving gears, and the top of the driving gear is meshed with a transmission gear. The side of the transmission gear is rotatably connected with an electric telescopic drive rod, and the top of the electric telescopic drive rod is rotatably connected with a glue outlet press head. One side of the driving gear is meshed with a force-bearing gear, and the side of the force-bearing gear is fixed with a reciprocating lead screw. The surface of the reciprocating lead screw is sleeved with a moving seat sleeve, and the side of the moving seat sleeve is fixed with a hollow scraper. The bottom of the pattern roller body conveys a release paper.

[0012] Further, the glue outlet press head is located inside the glue applicator box and is slidably connected with the glue applicator box.

[0013] Further, the side of the hollow scraper is attached to the connection part between the bottom side of one side of the glue applicator box and the surface of the pattern roller body, and a vision camera is arranged inside the hollow scraper.

[0014] Further, an L-shaped slot is opened inside the side of the glue applicator box away from the hollow scraper, and a first piston rod penetrates through one side of the L-shaped slot.

[0015] Further, a first micro oil cylinder is arranged on the outer wall of the end of the first piston rod, and the end of the first micro oil cylinder is connected with a transmission channel.

[0016] Further, the end of the transmission channel is connected with a second micro oil cylinder, and a second piston rod penetrates through the end of the second micro oil cylinder.

[0017] Further, the end of the second piston rod penetrates into the L-shaped slot, and the second piston rod and the first piston rod are respectively located on both sides of the L-shaped slot.

[0018] Furthermore, a scraper assembly is inserted into the L-shaped slot. The scraper assembly includes an L-shaped plug, a scraper housing, and a scraper body. The end of the L-shaped plug is fixed with the scraper housing, and the scraper body is arranged inside the scraper housing and the scraper body is attached to the surface of the pattern roller body.

[0019] Furthermore, the side of the scraper housing is attached to the bottom of the side of the glue application box away from the hollow scraper, and rubber sealing strips are arranged at both the inner bottom of the bottom of the scraper housing and the inner wall bottom of the side of the glue application box close to the hollow scraper.

[0020] The present invention provides a preparation method for a jelly glue hole glue hot melt adhesive film, which has the following beneficial effects:

[0021] 1. In the preparation method of the jelly glue hole glue hot melt adhesive film, the rotation of the pattern roller body itself drives the glue outlet press head to perform a piston motion inside the glue application box, and at the same time, the glue liquid is continuously injected, so that the glue liquid is fully attached to the surface of the pattern roller body under the action of the piston. It is applicable to grooves and convex surfaces with different size designs on the surfaces of different pattern roller bodies to prevent the product forming quality from being reduced due to insufficient filling of the glue liquid. Moreover, the rotation of the pattern roller body also drives the hollow scraper to slide back and forth along the pattern roller body and the outer wall of the glue application box, and a vision camera is used to detect whether there is glue overflow or leakage problem. If a glue leakage problem occurs, the electric telescopic transmission rod is controlled to contract to adjust the pressing distance of the glue outlet press head, so as to reduce the pressure on the glue liquid inside the glue application box and avoid the glue liquid from leaking out.

[0022] 2. In the preparation method of the jelly glue hole glue hot melt adhesive film, the scraper housing and the glue application box are assembled together, so that the scraper body is located inside the glue application box to scrape off the excess glue liquid, and the excess glue liquid still remains inside the glue application box for continued use. At the same time, by using oil hydraulic transmission and the on-off control of the solenoid valve, the firm clamping and quick disassembly and assembly of the scraper housing and the scraper body can be realized, so as to facilitate the replacement and maintenance of the scraper body in the later stage and reduce the time-consuming for replacement and maintenance.

[0029] The following further describes the implementation manners of the present invention in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] As Figures 1 - 5 shown, the present invention provides a technical solution: A preparation method of a jelly glue - hole glue hot - melt adhesive film, and the preparation method of the jelly glue - hole glue hot - melt adhesive film includes the following steps:

[0031] Step 1: A glue - conveying hose is connected to the top surface of the glue - discharging press head 107, and the glue liquid flows out from the bottom of the glue - discharging press head 107 and is injected into the glue - coating box 103. The pattern roller body 102 rotates while being attached to the glue - coating box 103 so that the glue liquid adheres to the surface of the pattern roller body 102. The surface of the pattern roller body 102 is designed with grooves and convex surfaces, and the grooves are used to accommodate the glue liquid;

[0032] Step 2: When the pattern roller body 102 rotates, it drives the driving gear 104 to rotate, thereby causing the transmission gear 105 to rotate. The transmission gear 105 rotates and drives the electric telescopic transmission rod 106 so that the glue - discharging press head 107 makes a lifting piston movement along the inside of the glue - coating box 103, thereby continuously pressing down the glue liquid and making the glue liquid fully fill the grooves on the surface of the pattern roller body 102;

[0033] Step 3: As the pattern roller body 102 rotates and passes by the scraper body 803, the scraper body 803 scrapes off the glue liquid that is higher than the convex surface. Then, as the pattern roller body 102 continues to rotate, the glue liquid in the grooves is carried out together with the surface of the release paper during transmission, thus completing the production of the hole - shaped hot - melt adhesive film;

[0034] Step 4: While the driving gear 104 rotates, it will also drive the force-bearing gear 108 to rotate the reciprocating lead screw 109. The reciprocating lead screw 109 rotates to carry the moving seat sleeve 110, which drives the hollow scraping plate 111 to slide back and forth along the outer walls of the pattern roller body 102 and the glue application box 103. By the back-and-forth movement of the hollow scraping plate 111 and in cooperation with the vision camera to detect whether there is glue liquid inside, it is determined whether there is glue leakage at the bottom side of the glue application box 103;

[0035] If glue leakage occurs, the electric telescopic transmission rod 106 is controlled to contract to adjust the pressing distance of the glue outlet press head 107, so as to reduce the pressure on the glue liquid inside the glue application box 103.

[0036] As Figures 1 - 5 shown, the preparation method of the jelly glue hole hot melt adhesive film is applied with a pattern roller assembly 1. The pattern roller assembly 1 includes a driving shaft 101, a pattern roller body 102, a glue application box 103, a driving gear 104, a transmission gear 105, an electric telescopic transmission rod 106, a glue outlet press head 107, a force-bearing gear 108, a reciprocating lead screw 109, a moving seat sleeve 110 and a hollow scraping plate 111. The surface of the driving shaft 101 is fixed with the pattern roller body 102, and the top surface of the pattern roller body 102 is provided with the glue application box 103. Both ends of the driving shaft 101 are sleeved with the driving gear 104, and the top of the driving gear 104 is meshed with the transmission gear 105. The side of the transmission gear 105 is rotatably connected with the electric telescopic transmission rod 106, and the top of the electric telescopic transmission rod 106 is rotatably connected with the glue outlet press head 107. One side of the driving gear 104 is meshed with the force-bearing gear 108, and the side of the force-bearing gear 108 is fixed with the reciprocating lead screw 109. The surface of the reciprocating lead screw 109 is sleeved with the moving seat sleeve 110, and the side of the moving seat sleeve 110 is fixed with the hollow scraping plate 111. A release paper is conveyed at the bottom of the pattern roller body 102. The glue outlet press head 107 is located inside the glue application box 103 and is slidably connected with the glue application box 103. The side of the hollow scraping plate 111 is attached to the connection between the bottom side of one side of the glue application box 103 and the surface of the pattern roller body 102, and a vision camera is arranged inside the hollow scraping plate 111;

[0037] The specific operation is as follows. A glue delivery hose is connected to the top surface of the glue outlet nozzle 107. The glue flows out from the bottom of the glue outlet nozzle 107 and is injected into the inside of the glue coating box 103. The pattern roller body 102 is attached to the glue coating box 103 and rotates, causing the glue to adhere to the surface of the pattern roller body 102. The surface of the pattern roller body 102 is designed with grooves and convex surfaces. The grooves are used to hold the glue, and the specific dimensions and spacing of the grooves and convex surfaces are designed according to requirements. When the pattern roller body 102 rotates, it drives the driving gear 104 to rotate, thereby causing the transmission gear 105 to rotate. The transmission gear 105 rotates and drives the electric telescopic transmission rod 106, causing the glue outlet nozzle 107 to perform a lifting piston movement inside the glue coating box 103. Thus, the glue is continuously pressed down, enabling the glue to fully fill the grooves on the surface of the pattern roller body 102. As the pattern roller body 102 rotates and passes by the blade body 803, the blade body 803 scrapes off the glue that is higher than the convex surface. Then, as the pattern roller body 102 continues to rotate, the glue in the grooves is carried out together with the surface of the transfer release paper during transmission, thereby completing the production of the porous hot melt adhesive film. While the driving gear 104 rotates, it also drives the force-bearing gear 108, causing the reciprocating lead screw 109 to rotate. The reciprocating lead screw 109 rotates to carry the moving seat sleeve 110, causing it to drive the hollow-out scraper 111 to slide back and forth along the outer walls of the pattern roller body 102 and the glue coating box 103. By the back-and-forth movement of the hollow-out scraper 111 and in cooperation with the vision camera to detect whether there is glue inside, it is determined whether there is glue leakage at the bottom of the side of the glue coating box 103. If glue leakage occurs, the electric telescopic transmission rod 106 is controlled to contract to adjust the pressing distance of the glue outlet nozzle 107, so as to reduce the pressure on the glue inside the glue coating box 103;

[0038] Based on the above description, the present invention utilizes the rotation of the pattern roller body 102 itself to drive the glue outlet nozzle 107 to perform a piston movement inside the glue coating box 103, while continuously injecting glue, so that the glue is fully adhered to the surface of the pattern roller body 102 under the action of the piston. It is applicable to grooves and convex surfaces with different size designs on the surfaces of different pattern roller bodies 102, to prevent the product forming quality from being reduced due to incomplete glue filling. Moreover, the rotation of the pattern roller body 102 also drives the hollow-out scraper 111 to slide back and forth along the outer walls of the pattern roller body 102 and the glue coating box 103, and the vision camera is used to detect whether there is glue overflow or leakage. If glue leakage occurs, the electric telescopic transmission rod 106 is controlled to contract to adjust the pressing distance of the glue outlet nozzle 107, so as to reduce the pressure on the glue inside the glue coating box 103, to avoid glue leakage.

[0039] Such as Figures 1 - 5As shown in the figure, an L-shaped slot 2 is provided inside the glue application box 103 on the side far from the hollow scraping blade 111. A first piston rod 3 penetrates through one side of the L-shaped slot 2. A first micro oil cylinder 4 is arranged on the outer wall of the end of the first piston rod 3. A transmission channel 5 is connected to the end of the first micro oil cylinder 4. A second micro oil cylinder 6 is connected to the end of the transmission channel 5. A second piston rod 7 penetrates through the end of the second micro oil cylinder 6. The end of the second piston rod 7 penetrates into the L-shaped slot 2. The second piston rod 7 and the first piston rod 3 are respectively located on both sides of the L-shaped slot 2. A scraping blade assembly 8 is inserted into the L-shaped slot 2. The scraping blade assembly 8 includes an L-shaped plug-in 801, a scraping blade housing 802, and a scraping blade body 803. The end of the L-shaped plug-in 801 is fixed with the scraping blade housing 802. The scraping blade body 803 is arranged inside the scraping blade housing 802. The scraping blade body 803 is attached to the surface of the pattern roller body 102. The side of the scraping blade housing 802 is attached to the bottom of the glue application box 103 on the side far from the hollow scraping blade 111. Rubber sealing strips are arranged on the inner side of the bottom of the scraping blade housing 802 and the inner wall bottom of the glue application box 103 close to the hollow scraping blade 111 side;

[0040] The specific operation is as follows. When the scraping blade body 803 receives glue on the surface of the pattern roller body 102 and continues to rotate, the excess glue outside the convex surface of its surface is scraped off. The installation process of the scraping blade body 803 is as follows. First, the L-shaped plug-in 801 is inserted into the L-shaped slot 2. At this time, the scraping blade housing 802 and the glue application box 103 are misaligned. By pushing the scraping blade housing 802, the L-shaped plug-in 801 is translated, so that the scraping blade housing 802 and the glue application box 103 are flush. At this time, because the L-shaped plug-in 801 is translated, the first piston rod 3 is pushed into the first micro oil cylinder 4. The transmission medium such as oil in the first micro oil cylinder 4 enters the second micro oil cylinder 6 along the transmission channel 5, so as to push the second piston rod 7 to extend to abut against the side of the L-shaped plug-in 801 far from the first piston rod 3. Then the solenoid valves at the ends of the first micro oil cylinder 4 and the second micro oil cylinder 6 are closed. Thus, the scraping blade housing 802 carries the scraping blade body 803 and is firmly fixed at the bottom of one side of the glue application box 103. When it is necessary to disassemble and replace the scraping blade body 803 later, just open the solenoid valve and push the scraping blade housing 802 in the reverse direction. Then pull the scraping blade housing 802 outwards to quickly remove it, so as to facilitate the replacement of the scraping blade body 803;

[0041] Based on the above description, the scraping blade housing 802 of the present invention is assembled with the glue application box 103, so that the scraping blade body 803 is located inside the glue application box 103 to scrape off the excess glue, and the excess glue still remains inside the glue application box 103 for continued use. At the same time, by using oil transmission and the on-off control of the solenoid valve, the firm clamping and quick disassembly and assembly of the scraping blade housing 802 and the scraping blade body 803 can be realized, so as to facilitate the later replacement and maintenance of the scraping blade body 803 and reduce the time-consuming of replacement and maintenance.

[0042] In summary, for the preparation method of the jelly glue hole glue hot melt adhesive film, during use, first, a glue delivery hose is connected to the top surface of the glue outlet nozzle 107. The glue liquid flows out from the bottom of the glue outlet nozzle 107 and is injected into the inside of the glue-coating box 103. The pattern roll body 102 is attached to the glue-coating box 103 and rotates, causing the glue liquid to adhere to the surface of the pattern roll body 102;

[0043] When the pattern roll body 102 rotates, it drives the driving gear 104 to rotate, thereby causing the transmission gear 105 to rotate. The transmission gear 105 rotates and drives the electric telescopic transmission rod 106, causing the glue outlet nozzle 107 to perform a lifting piston movement along the inside of the glue-coating box 103. Thus, the glue liquid is continuously pressed down, enabling the glue liquid to fully fill the grooves on the surface of the pattern roll body 102. As the pattern roll body 102 rotates and passes by the blade body 803, the blade body 803 scrapes off the glue liquid that is higher than the convex surface. Then, as the pattern roll body 102 continues to rotate, the glue liquid in the grooves is carried out together with the surface of the transfer release paper during transmission, thus completing the production of the hole-shaped hot melt adhesive film;

[0044] While the driving gear 104 rotates, it also drives the force-bearing gear 108, causing the reciprocating lead screw 109 to rotate. The reciprocating lead screw 109 rotates to carry the moving seat sleeve 110, causing it to drive the hollow-out scraper 111 to slide back and forth along the outer walls of the pattern roll body 102 and the glue-coating box 103. By the back-and-forth movement of the hollow-out scraper 111 and in cooperation with the vision camera to detect whether there is glue liquid inside, it is determined whether there is glue leakage at the bottom side of the glue-coating box 103. If glue leakage occurs, the electric telescopic transmission rod 106 is controlled to contract to adjust the pressing distance of the glue outlet nozzle 107, so as to reduce the pressure on the glue liquid inside the glue-coating box 103;

[0045] When the blade body 803 receives glue on the surface of the pattern roll body 102 and continues to rotate, it scrapes off the excess glue liquid outside the convex surface of its surface. The installation process of the blade body 803 is as follows. First, the L-shaped plug-in 801 is inserted into the inside of the L-shaped slot 2. At this time, the blade housing 802 is misaligned with the glue-coating box 103. By pushing the blade housing 802, the L-shaped plug-in 801 is translated, so that the blade housing 802 is flush with the glue-coating box 103. And at this time, due to the translation of the L-shaped plug-in 801, the first piston rod 3 is pushed into the first micro-cylinder 4. The transmission medium in the first micro-cylinder 4, such as oil, enters the second micro-cylinder 6 along the transmission channel 5, thereby pushing the second piston rod 7 to extend and abut against the side of the L-shaped plug-in 801 away from the first piston rod 3. Then, the solenoid valves at the ends of the first micro-cylinder 4 and the second micro-cylinder 6 are closed, thereby causing the blade housing 802 to firmly fix the blade body 803 to the bottom side of the glue-coating box 103;

[0046] When the blade body 803 needs to be disassembled and replaced later, just open the solenoid valve and push the blade housing 802 backward, and then pull the blade housing 802 outward to quickly remove it, thus facilitating the replacement of the blade body 803.

Many modifications and variations are obvious to those of ordinary skill in the art.
