TECHNICAL FIELD

[0001] The utility model relates to the production technical field of release paper, especially relates to a kind of release paper membrane machine's anti-sticking device. BACKGROUND

[0002] Release paper is a kind of special paper with anti-sticking performance, and is widely used in adhesive label, medical supplies and other fields. In the production process of release paper, the membrane process is a key link, which requires coating release agent on the surface of the substrate. However, the release agent is easy to adhere to the surface of the equipment during high-temperature curing, resulting in low production efficiency and unstable product quality. At present, the industry mainly solves this problem by improving the formula of release agent or increasing the cleaning frequency of the equipment. However, these methods are either costly or affect production efficiency. In recent years, with the rapid growth of demand for release paper, the development of efficient and low-cost anti-sticking technology has become an urgent need in the industry.

[0003] After searching, Chinese patent literature publication number CN214831523U discloses a kind of release paper membrane machine's anti-sticking device, including mounting plate, the upper surface middle part of mounting plate is provided with rubber roller, the upper surface one side of mounting plate is provided with sliding slot, two-way screw rod is arranged in sliding slot, sliding block is arranged in sliding slot, the middle part of sliding block is provided with screw groove, the top of sliding block is fixedly connected with support rod, the top of support rod is fixedly connected with extension rod, one end of extension rod is fixedly connected with arc block. The utility model discloses that the sliding block is arranged in the sliding slot opened in the upper surface of mounting plate, the sliding block drives the arc block to move through support rod, the sponge block on one side of arc block is attached to rubber roller, the liquid plastic adhered to the outside of rubber roller is wiped off by sponge block, to avoid affecting the subsequent membrane work, the anti-sticking agent arranged in the cavity of arc block enters sponge block through through hole, so that the adhesion of sponge block to liquid plastic during work is ensured.

[0004] The above-mentioned patent has the beneficial effect of: "by arranging a sliding block in the sliding slot opened on the upper surface of the mounting plate, the sliding block drives the arc block to move through the support rod, the sponge block on one side of the arc block is attached to the rubber roller, the liquid plastic adhered to the outside of the rubber roller is wiped off by the sponge block, to avoid affecting the subsequent membrane work, the anti-sticking agent arranged in the cavity of the arc block enters the sponge block through the through hole, so that the adhesion of the sponge block to the liquid plastic during work is ensured". Although the above-mentioned scheme can solve the problem, the air jet structure in the anti-sticking device of some release paper membrane machines in the prior art cannot effectively jet air to both sides of the anti-sticking roller during air jet cleaning, which makes it difficult to timely remove the sticky substances on the edge of the anti-sticking roller, affecting the production quality of release paper and the working efficiency of the anti-sticking device. Therefore, there is a problem of incomplete cleaning and insufficient area coverage, and a kind of release paper membrane machine's anti-sticking device is proposed to solve the above-mentioned problem. UTILITY MODEL CONTENTS

[0005] To overcome the above shortcomings, this utility model provides an anti-sticking device for a release paper coating machine. It aims to improve the existing technology where the air jet structure cannot effectively spray air onto both sides of the anti-sticking roller when cleaning it, resulting in the sticky material on the edge of the anti-sticking roller being difficult to remove in time. This affects the production quality of the release paper and the working efficiency of the anti-sticking device, and there are problems of incomplete cleaning and insufficient area coverage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-sticking device for a release paper coating machine includes a base frame, a first fixing plate fixedly connected to the top of the base frame, a second fixing plate fixedly connected to the top of the base frame, an adjustment mechanism fixedly connected to the front side of the second fixing plate, a dust removal mechanism fixedly connected to the rear side of the first fixing plate, a lifting mechanism fixedly connected to the bottom inner wall of the base frame, and a conveying roller fixedly connected to the rear side of the second fixing plate.

[0008] The adjustment mechanism includes a motor, the rear side of which is fixedly connected to the front side of the second fixed plate. A rotating rod is fixedly connected to the drive end of the motor, and a gear is fixedly connected to the rear side of the rotating rod. A guide plate is fixedly connected to the inner wall of the second fixed plate. A rack is fixedly connected to the bottom of the guide plate. A connecting plate is fixedly connected to the top of the rack. An air jet assembly for blowing air is fixedly connected to the top of the connecting plate.

[0009] Through the above technical solution: when the anti-sticking roller is running, the high-pressure air pump and negative pressure fan are started to clean the anti-sticking roller. Then, the motor drives the gear to rotate, which moves the rack and pinion, thereby moving the connecting plate to adjust the hose and allowing the nozzle to be adjusted left and right.

[0010] As a further description of the above technical solution:

[0011] The lifting mechanism includes a hydraulic cylinder, the bottom of which is fixedly connected to the bottom inner wall of the base frame, a push block is fixedly connected to the drive end of the hydraulic cylinder, a limit block is fixedly connected to the top of the push block, a force-bearing block is slidably connected to the top of the base frame, and a scraper assembly for cleaning the surface is fixedly connected to the top of the force-bearing block.

[0012] The above technical solution works as follows: when the scraper needs to be adjusted up and down, the hydraulic cylinder moves the push block so that the force-bearing block receives force. Both the push block and the force-bearing block have inclined surfaces on their adjacent sides, which causes the force-bearing block to move upward, thereby driving the scraper assembly at the top center to move.

[0013] As a further description of the above technical solution:

[0014] The jet assembly includes a hose, the bottom of which is fixedly connected to the top of the connecting plate, a nozzle fixedly connected to the rear side of the hose, a connecting shell fixedly connected to the front side of the second fixing plate, a transmission pipe fixedly connected to the front side of the hose, and a high-pressure air pump fixedly connected to the other side of the transmission pipe.

[0015] The above technical solution involves a high-pressure air pump delivering gas through a transmission pipe into a flexible hose. A connecting shell secures the hose, allowing it to rotate around the shell. The nozzle receives the gas from the high-pressure air pump and discharges it from there.

[0016] As a further description of the above technical solution:

[0017] The scraper assembly includes a blade holder, the bottom of which is fixedly connected to the top of the force-bearing block, and an adjustable scraper is slidably connected to the top of the blade holder.

[0018] The above technical solution involves a threaded connection between the blade holder and the adjustable scraper. The blade holder supports the adjustable scraper, while the scraper cleans the surface of the anti-stick roller.

[0019] As a further description of the above technical solution:

[0020] The dust removal mechanism includes a fixed plate three, the front side of the fixed plate three is fixedly connected to the rear side of the fixed plate one, a negative pressure fan is fixedly connected to the rear side of the fixed plate three, and a dust collection hood is fixedly connected to the front side of the fixed plate three.

[0021] Through the above technical solution: the negative pressure fan is fixed on the fixed plate three. When the negative pressure fan is started, the dust collection hood receives the negative pressure airflow, which removes dust from the anti-stick roller, allowing the dust to be absorbed in the dust collection hood.

[0022] As a further description of the above technical solution:

[0023] The rack is meshed with the gear, and the rotating rod is rotatably connected to the inner wall of the fixed plate.

[0024] Through the above technical solution: the gear receives the rotational power of the rotating rod, thereby driving the rack to move, which in turn drives the hose to move; the rotating rod receives the power of the motor, thereby rotating, which in turn drives the gear to rotate.

[0025] As a further description of the above technical solution:

[0026] The bottom inner wall of the base frame is fixedly connected to a guide plate two, the bottom of the pushing block is slidably connected to the inside of the guide plate two, and the bottom of the limiting block is slidably connected to the top of the guide plate two.

[0027] Through the above technical solution: the second guide plate allows the push block to move linearly. The push block receives the pushing force of the hydraulic cylinder, which ultimately drives the limit block to apply force to the force plate, causing the force plate to move.

[0028] As a further description of the above technical solution:

[0029] The left side of the limiting block is in contact with the right side of the force-bearing block, and a slot is provided on the top of the base frame.

[0030] Through the above technical solution: the limiting block moves along with the pushing block, thereby driving the force plate to move upward; the slot allows the force plate to move here, thereby raising and lowering the scraper assembly at the top.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the motor drives the gear to rotate, which in turn causes the rack to move the hose left and right under the action of the guide plate. Under the high-pressure air pump of the jet assembly, high-pressure air is jetted onto the anti-stick roller, thereby realizing the adjustment of the jet head angle. In addition, the jet angle can be flexibly adjusted to accurately target the easily sticky area of ​​the release paper, enhance the airflow scouring effect, and thus improve the targeting and effectiveness of the anti-sticking.

[0033] 2. In this utility model, the cylinder causes the pushing block to move under the action of the guide plate, thereby pushing the limiting block against the force plate, causing the force plate to move upward, thereby raising and lowering the scraper assembly, thus realizing the adjustment of the scraper angle. In addition, the coating uniformity can be optimized by adjusting the scraper angle, reducing the risk of local adhesion caused by fixed angle, thereby improving the stability of the anti-adhesion effect.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 2 and Figure 3This utility model provides an embodiment of an anti-sticking device for a release paper coating machine, comprising a base frame 1, which is the foundation of the entire equipment and protects it. A first fixing plate 2 and a second fixing plate 3 are fixedly connected to the top of the base frame 1. Both fixing plates 2 and 3 are used to fix adjusting rollers. An adjusting mechanism 4 is fixedly connected to the front side of the second fixing plate 3, and a dust removal mechanism 6 is fixedly connected to the rear side of the first fixing plate 2. A lifting mechanism 8 is fixedly connected to the bottom inner wall of the base frame 1, and a conveying roller 7 is fixedly connected to the rear side of the second fixing plate 3. The first fixing plate 2 is used to fix the dust removal assembly, allowing it to operate. The first fixing plate 2 also fixes the adjusting mechanism 4, allowing the adjusting assembly to operate. The lifting mechanism adjusts the scraper in the equipment, allowing it to move up and down. The adjusting mechanism 4 includes a motor 41. The rear side of the motor 41 is fixedly connected to the front side of the fixed plate 2 3. The drive end of the motor 41 is fixedly connected to the rotating rod 42. The motor 41 is the drive source of the adjustment mechanism 4, thereby driving the rotating rod 42 to rotate. The rear side of the rotating rod 42 is fixedly connected to the gear 43. The inner wall of the fixed plate 2 3 is fixedly connected to the guide plate 1 44. The bottom of the guide plate 1 44 is fixedly connected to the rack 45. The top of the rack 45 is fixedly connected to the connecting plate 46. The gear 43 receives the rotational force of the rotating rod 42 and rotates. The rack 45 receives the rotational force of the gear 43 and rotates. The guide plate 1 44 allows the rack 45 to move linearly under the rotation of the gear 43. The connecting plate 46 connects the top jet assembly 5 and the bottom rack 45 and transmits the moving force of the rack 45 to the jet assembly 5. The top of the connecting plate 46 is fixedly connected to the jet assembly 5 for blowing air.

[0042] Specifically, the core component of the adjustment assembly is the connecting plate 46. The bottom of the connecting plate 46 receives the moving force of the rack 45 and transmits the moving force to the top jet assembly 5. The motor 41 causes the rotating rod 42 to rotate, thereby guiding the gear 43 to rotate, causing the rack 45 to rotate, which in turn drives the connecting plate 46 to move. The guide plate 44 inside the fixed plate 2 allows the rack 45 to move linearly when it moves under the action of the gear 43.

[0043] The jet assembly 5 includes a hose 51, the bottom of which is fixedly connected to the top of the connecting plate 46. The hose 51 is flexible and rotates as the connecting plate 46 moves. A nozzle 55 is fixedly connected to the rear side of the hose 51. The nozzle 55 is the main source of the jet assembly 5, from which gas is discharged. A connecting shell 52 is fixedly connected to the front side of the fixing plate 3. The connecting shell 52 is used to fix a part of the front side of the hose 51. A transmission pipe 53 is fixedly connected to the front side of the hose 51. A high-pressure air pump 54 is fixedly connected to the other side of the transmission pipe 53. The transmission pipe 53 receives the gas transmitted by the high-pressure air pump 54 and transmits it to the transmission pipe 53. The high-pressure air pump 54 generates gas and then transmits the gas to the transmission pipe 53. It is also the gas source of the jet assembly 5.

[0044] Specifically, the core component of the jet assembly 5 is the hose 51. The hose 51 receives the moving force of the connecting plate 46. The gas transmitted by the high-pressure air pump 54 is discharged at the nozzle 55 after passing through the transmission pipe 53. The connecting shell 52 allows the hose 51 to rotate around the inside of the connecting shell 52, thereby limiting the hose 51.

[0045] Reference Figure 2 and Figure 4 The lifting mechanism 8 includes a hydraulic cylinder 81. The bottom of the hydraulic cylinder 81 is fixedly connected to the bottom inner wall of the base frame 1. The driving end of the hydraulic cylinder 81 is fixedly connected to a push block 82. The hydraulic cylinder 81 is the driving source of the lifting mechanism 8, thereby driving the push block 82 to move. The top of the push block 82 is fixedly connected to a limit block 83. The top of the base frame 1 is slidably connected to a force-bearing block 84. The limit block 83 moves with the push block 82, thereby driving the force-bearing block 84 to move, causing its force plate to be impacted and move upward. The top of the force-bearing block 84 is fixedly connected to a scraper assembly 9 for cleaning the surface. The scraper assembly 9 receives the pushing force of the force plate and moves upward. The scraper assembly 9 includes a blade bracket 91. The bottom of the blade bracket 91 is fixedly connected to the top of the force-bearing block 84. The top of the blade bracket 91 is slidably connected to an adjustable scraper 92. The blade bracket 91 is used to fix the scraper to prevent the scraper from moving randomly. The adjustable scraper 92 is used to facilitate the disassembly of the scraper, thereby facilitating the replacement of the scraper.

[0046] Specifically, the core of the lifting mechanism 8 is the push block 82, which receives the pushing force of the hydraulic cylinder 81, thereby causing the limit block 83 to move, which in turn causes the force plate to move, allowing the force plate to slide up and down on the top of the base frame 1, thus moving the top scraper assembly 9. The adjustable scraper 92 and the blade bracket 91 are connected by bolts, making it convenient for the operator to replace the scraper.

[0047] Reference Figures 1 to 3The dust removal mechanism 6 includes a fixed plate 3 62, the front of which is fixedly connected to the rear of the fixed plate 1 2. The fixed plate 3 62 is the connecting component of the dust removal mechanism 6, serving as a connecting pipe that fixes the negative pressure fan 61 and the internal dust collection hood 63. The negative pressure fan 61 is fixedly connected to the rear of the fixed plate 3 62. The negative pressure fan 61 receives the power signal from the equipment and thus sucks dust from the dust collection hood 63. The dust collection hood 63 is fixedly connected to the front of the fixed plate 3 62. The dust collection hood 63 absorbs dust from the anti-stick roller. The outside of the rack 45 meshes with the outside of the gear 43. The rack 45 receives the rotational force from the gear 43 and thus moves. The outside of the rotating rod 42 is rotatably connected to the inner wall of the fixed plate 2 3. The rotating rod 42 receives power from the motor 41 and rotates inside the fixed plate 2 3. The bottom inner wall of the base frame 1 is fixedly connected to the guide plate 2 85. The bottom of the pushing block 82 is slidably connected to the inside of the guide plate 2 85. The guide plate 2 85 allows the pushing block 82 to move linearly when it receives the pushing force of the hydraulic cylinder 81. The bottom of the limiting block 83 is slidably connected to the top of the guide plate 2 85. The limiting block 83 moves linearly under the movement of the pushing block 82. The left side of the limiting block 83 contacts the right side of the force-bearing block 84. After the limiting block 83 receives the force-bearing block 84, it drives the force-bearing block 84 to move upward. The top of the base frame 1 has a slot, which allows the force-bearing plate to move here.

[0048] Working principle: The operator turns on the high-pressure air pump 54, allowing the air from the high-pressure air pump 54 to enter the transmission pipe 53, then enter the hose 51 and exit through the nozzle 55. At this time, the operator starts the motor 41, which drives the rotating rod 42 to rotate, thereby driving the gear 43 to rotate, which guides the rack 45 to move under the action of the guide plate 44. This causes the rack 45 to drive the top hose 51 to adjust its angle, which in turn drives the nozzle 55 to adjust its angle. At the same time, the operator also turns on the negative pressure fan 61, which draws air into the dust collection hood 63. Under the action of the jet assembly 5 and the dust removal assembly, and the action of the adjusting mechanism 4, the surface of the anti-sticking roller is cleaned, thereby achieving the adjustment of the jet head angle. In addition, the jet angle can be flexibly adjusted to accurately target the easily sticking areas of the release paper, enhancing the airflow scouring effect and improving the targeting and effectiveness of the anti-sticking.

[0049] The cylinder drives the push block 82 to move, which in turn drives the top limiting block 83 to move, thus subjecting the force block 84 to force. Under the action of the limiting block 83, the force block 84 moves upward, thereby driving the entire scraper assembly 9 to move upward. This achieves the adjustment of the scraper angle. In addition, adjusting the scraper angle can optimize the coating uniformity, reduce the risk of local adhesion caused by a fixed angle, and thus improve the stability of the anti-adhesion effect.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
