Description

Technical Field

[0001] This invention relates to the field of coating dust removal technology, specifically a coating dust removal device for digital printing equipment. Background Technology

[0002] Currently, in digital printing equipment, the corresponding pattern needs to be printed on the corresponding label first, and then a PET heat shrink film is applied to the corresponding patterned label to ensure the cleanliness of the finished product and avoid contamination of the finished material.

[0003] Patent publication number CN114643707B discloses a lamination dust removal device for digital printing equipment, including a rotating roller with a label wrapped around it after lamination, and a first rotating roller and a second rotating roller with a label and PET heat shrink film wrapped around them respectively. An L-shaped dust removal plate is arranged between the rotating roller, the first rotating roller, and the second rotating roller, and the L-shaped dust removal plate is connected to the roller via a spacing adjustment device. This patent uses a dust discharge hole that communicates with the space between two adjacent driving rollers through a dust removal cylinder. This design aims to ensure that the side of the PET heat shrink film that is attached to the label contacts the driving roller. This not only causes the vertically arranged PET heat shrink film to rotate the driving roller due to friction, but also allows the continuously rotating piston inside the dust removal cylinder between the two adjacent driving rollers to better remove dust from the PET heat shrink film facing the label. The continuous reciprocating motion of the rotating piston also cleans dust from the side wall of the telescopic cylinder.

[0004] However, the device still has shortcomings: the device removes dust using PET heat shrink film, but the PET heat shrink film is prone to wrinkling during the lamination process, which reduces the regularity of the lamination and the dust removal effect, and to some extent reduces the cleanliness of the finished product. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lamination dust removal device for digital printing equipment, which solves the problem mentioned in the background art that PET heat shrink film is prone to wrinkling during the lamination process, thereby reducing the regularity of the lamination and the dust removal effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coating dust removal device for digital printing equipment, comprising a main body, a fixed plate on the top of the main body, a U-shaped plate on the top of the fixed plate, and further comprising an anti-wrinkle device, an adsorption device, an anti-pollution device, and an anti-adhesion device. The anti-wrinkle device is disposed inside the fixed plate, the adsorption device is disposed on the top of the inner wall of the U-shaped plate, the anti-pollution device is disposed inside the adsorption device, and the anti-adhesion device is disposed on the left and right sides of the inner wall of the U-shaped plate. The anti-wrinkle device comprises an electric rotating shaft, a roller, and a dust removal plate. The back of the electric rotating shaft is rotatably mounted at the center of the front of the fixed plate. When the electric rotating shaft is started, it drives the roller to rotate. The inside of the roller is fixedly mounted on the outer wall surface of the electric rotating shaft, and a PET heat shrink film is sleeved on the outer wall of the roller. The roller drives the PET heat shrink film to automatically coat the material, simplifying the coating process. The back of the dust removal plate is fixedly mounted on the front of the fixed plate, and the bottom of the dust removal plate contacts the top of the PET heat shrink film. When the PET heat shrink film is running, it contacts the bottom of the dust removal plate to scrape off the dust on the surface of the PET heat shrink film.

[0007] According to the above technical solution, the anti-wrinkle device further includes a rotating column, an adhesion wheel, a throbbing plate, and a telescopic rod. The back of the rotating column is rotatably mounted on the front of the fixed plate. The adhesion wheel drives the rotating column to rotate. The adhesion wheel is fixedly mounted on the outer wall surface of the rotating column, and a circular groove is provided on the outer wall of the adhesion wheel. When the PET heat shrink film rotates, it contacts the outer wall of the adhesion wheel, generating frictional resistance that causes the adhesion wheel to rotate. The adhesion wheel drives the rotating column to rotate. When the adhesion wheel rotates, it expands the dust removal range and dust removal quality of the dust removal plate. The bottom of the throbbing plate is fixedly mounted on the inner wall of the circular groove of the adhesion wheel, and the arc surface of the throbbing plate contacts the top of the PET heat shrink film. The adhesion wheel drives the throbbing plate to rotate. When the throbbing plate contacts the PET heat shrink film, it causes friction, and the throbbing plate shrinks and deforms due to the frictional force. The bottom of the telescopic rod is fixedly mounted on the concave surface of the outer wall of the adhesion wheel, and the top of the telescopic end of the telescopic rod is fixedly connected to the bottom of the throbbing plate. A spring is provided at the telescopic end of the telescopic rod. When the throbbing plate recovers its elasticity, it stretches the PET heat shrink film with tension, preventing the material from sticking to the PET heat shrink film during the lamination process.

[0008] According to the above technical solution, the adsorption device includes an electric slide rail, an adsorption component, and a collection bucket. The top of the electric slide rail is fixedly installed on the top of the inner wall of the U-shaped plate. When the electric slide rail is activated, it drives the adsorption component to slide left and right to adsorb flying dust. The outer wall of the adsorption component is slidably installed inside the electric slide rail. The adsorption component drives the collection bucket to move synchronously. The bottom of the collection bucket is through and fixedly installed on the top of the adsorption component, and the bottom of the collection bucket is provided with filter holes. The collection bucket collects the dust adsorbed by the adsorption component in a concentrated manner, which is convenient for staff to clean.

[0009] According to the above technical solution, the adsorption device further includes an electric rotating rod, a round rod, a convex ball block, and a reset plate. The bottom of the electric rotating rod is rotatably installed at the center of the bottom of the inner wall of the collection bucket, and an arc-shaped groove is opened on the outer wall of the electric rotating rod. When the electric rotating rod is started, the electric rotating rod drives the round rod to rotate, and the round rod drives the convex ball block to rotate. The right side of the round rod is fixedly installed on the left side of the outer wall of the electric rotating rod. The convex ball block rotates and agitates the dust inside the collection bucket, causing the dust to be evenly distributed inside the collection bucket. The convex ball block is rotatably installed on the outer wall surface of the round rod, and the outer wall of the convex ball block contacts the inner wall of the filter hole. When the convex ball block contacts the filter hole, it generates resistance and starts to rotate. When the convex ball block rotates, it removes the sticky dust adhering to the inner wall of the filter hole of the collection bucket. The front side of the reset plate is fixedly installed on the back side of the outer wall of the round rod. The round rod drives the reset plate to rotate, and the reset plate contacts and removes the solidified dirt adhering to the bottom of the inner wall of the collection bucket.

[0010] According to the above technical solution, the anti-pollution device includes a connecting rod, a heating ring, and a central arc plate. The right side of the connecting rod is slidably installed inside the arc groove of the electric rotating rod. When the electric rotating rod rotates, the arc groove restricts the connecting rod, enabling it to move up and down. The left side of the inner wall of the heating ring is fixedly installed on the left side of the connecting rod, and the outer wall of the heating ring is slidably connected to the inner wall of the collection bucket. The connecting rod drives the heating ring to slide synchronously along the inner wall of the collection bucket. The heating ring scrapes the inner wall of the collection bucket to reduce dirt adhesion. The central arc plate is fixedly installed between the top of the heating ring and the inner wall of the collection bucket. The heating ring squeezes the central arc plate and deforms synchronously to restore its original shape. The central arc plate pushes the dust in a central position.

[0011] According to the above technical solution, the anti-pollution device further includes a U-shaped pull plate, a purification bag, a spray gun, and an L-shaped baffle. The right outer wall of the U-shaped pull plate is penetrated and fixedly installed inside the convex surface of the central arc plate. The central arc plate drives the U-shaped pull plate to move left and right. The convex surface of the purification bag is fixedly installed at the concave surface of the inner wall of the collection bucket, and the right side of the purification bag is fixedly connected to the left side of the U-shaped pull plate. The U-shaped pull plate pulls the purification bag to deform synchronously and generate spray force. The bottom of the spray gun is fixedly installed at the top of the purification bag. The purification bag sprays the purification agent into the collection bucket through the spray gun to purify the oily and damp bacteria growing inside the collection bucket. The bottom of the L-shaped baffle is fixedly installed at the top of the U-shaped pull plate, and the top left side of the L-shaped baffle is located directly above the spray gun. When the L-shaped baffle is reset, it blocks the nozzle of the spray gun to prevent external dirt from entering the purification bag and contaminating the purification agent.

[0012] According to the above technical solution, the anti-adhesion device includes an elastic plate, a U-shaped pressure roller, and a swing plate. The top left side of the elastic plate is fixedly installed on the left side of the inner wall of the electric slide rail, and the right side of the elastic plate is fixedly connected to the left side of the outer wall of the adsorption component. When the adsorption component slides left and right, it squeezes the elastic plate to deform and return to its original shape. The elastic plate drives the U-shaped pressure roller to move up and down. The top outer wall of the U-shaped pressure roller penetrates through and is fixedly installed inside the convex surface of the elastic plate. The pressure roller is rotatably installed. When the U-shaped pressure roller moves downward, it abuts against the right edge of the swing plate and bends downward. The left side of the swing plate is fixedly installed on the left side of the inner wall of the U-shaped plate, and the top of the swing plate contacts the bottom of the outer wall of the U-shaped pressure roller. When the swing plate returns to its original position through its own elasticity, it swings up and down repeatedly. The swing plate beats the flying dust attracted by the adsorption component.

[0013] According to the above technical solution, the anti-adhesion device further includes a twisting plate, a striking column, a sliding plate, and a telescopic shovel. The top right side of the twisting plate is fixedly installed at the bottom edge of the swing plate. When the swing plate swings, it causes the twisting plate to deform and return to its original shape. The bottom of the striking column is fixedly installed at the concave surface of the inner wall of the twisting plate, and the top of the striking column contacts the bottom of the swing plate. The twisting plate drives the striking column to repeatedly strike the bottom of the swing plate to generate vibration. The swing plate uses vibration force to irregularly beat the dust. The bottom of the sliding plate is fixedly installed at the top left side of the twisting plate, and the top of the sliding plate is slidably connected to the bottom of the swing plate. The twisting plate drives the sliding plate to slide left and right along the bottom of the swing plate. When the sliding plate slides, it agitates the dirt attached to the bottom of the swing plate, preventing the dust from adhering and accumulating with each other. The right side of the telescopic shovel is fixedly installed at the left side of the sliding plate, and the telescopic end of the telescopic shovel is provided with a spring. The telescopic shovel uses stored force to shovel the solidified material at the bottom of the swing plate, preventing the solidified material generated during equipment operation from being corrosive.

[0014] This invention provides a lamination dust removal device for digital printing equipment. It has the following beneficial effects:

[0015] (1) The present invention uses an anti-wrinkle device, which combines an electric rotating shaft, a roller, and a dust removal plate. The roller drives the PET heat shrink film to automatically coat the material, simplifying the coating process. At the same time, the dust removal plate scrapes away dust on the surface of the PET heat shrink film, ensuring the cleanliness of the PET heat shrink film surface. The combination of a rotating column, an adhesion wheel, a drum plate, and a telescopic rod expands the dust removal range and quality of the dust removal plate when the adhesion wheel rotates. At the same time, the rotation of the adhesion wheel makes the PET heat shrink film straighter during coating, avoiding wrinkles. Meanwhile, the telescopic rod provides good support for the drum plate through the elasticity of the spring, preventing the drum plate from being over-deformed and difficult to recover in time. It also allows the PET heat shrink film to be stretched under tension when the drum plate recovers, avoiding mutual adhesion between the material and the PET heat shrink film during the coating process, ensuring the neatness of the coating.

[0017] (3) The present invention, through the setting of the anti-pollution device, through the cooperation of electric rotating rod, connecting rod, heating ring and central arc plate, makes the heating ring scrape the inner wall of the collection bucket to reduce dirt adhesion, and at the same time prevent the dust contaminated with equipment oil from being corroded by moisture and growing mold in rainy weather, ensuring that the inside of the collection bucket is dry; at the same time, the central arc plate pushes the dust in the center, reducing the adhesion area of ​​dust to the inner wall of the collection bucket; through the cooperation of U-shaped pull plate, purification bag, spray gun and L-shaped shield, the purification bag sprays the purification agent into the inside of the collection bucket through the spray gun to purify the oily and moist bacteria, avoiding the health hazards caused by the adsorption of bacteria into the body by maintenance personnel during cleaning, and providing a safe working environment; and the L-shaped shield also blocks the nozzle of the spray gun to prevent external dirt from entering the purification bag and contaminating the purification agent, preventing the purification effect from being reduced.

[0018] (4) The present invention, through the setting of the anti-adhesion device, through the cooperation of the adsorption component, elastic plate, U-shaped pressure roller and swing plate, makes the U-shaped pressure roller resist the deformation of the swing plate, the pressure roller improves the passage of the swing plate, and the swing plate beats the flying dust attracted by the adsorption component, preventing the adsorption component from not absorbing enough and causing secondary adhesion to the PET heat shrink film; through the cooperation of the twisting plate, the striking column, the sliding plate and the telescopic shovel, the striking column strikes the bottom of the swing plate to generate vibration, and the swing plate beats the dust irregularly through the vibration force; at the same time, when the sliding plate slides, it tamps the dirt attached to the bottom of the swing plate, avoiding the dust from sticking and agglomerating with each other and reducing the beating effect of the swing plate; it also makes the telescopic shovel forcefully shovel the solidified material at the bottom of the swing plate, avoiding the solidified material generated during the operation of the equipment being corrosive, preventing the outer wall of the swing plate from being corroded and pitted, and extending the maintenance cycle of the swing plate and other components.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figure 1-8One embodiment of the present invention is: a coating dust removal device for digital printing equipment, comprising a device body 1, a fixing plate 2 on the top of the device body 1, a U-shaped plate 3 on the top of the fixing plate 2, and an anti-wrinkle device 4 and an adsorption device 5. The anti-wrinkle device 4 is disposed inside the fixing plate 2, and the adsorption device 5 is disposed on the top of the inner wall of the U-shaped plate 3. The anti-wrinkle device 4 includes an electric rotating shaft 41, a roller 42, and a dust removal plate 43. The back of the electric rotating shaft 41 is rotatably mounted at the center of the front of the fixing plate 2. The inside of the roller 42 is fixedly mounted on the outer wall surface of the electric rotating shaft 41, and a PET heat shrink film is sleeved on the outer wall of the roller 42. The back of the dust removal plate 43 is fixedly mounted on the front of the fixing plate 2, and the bottom of the dust removal plate 43 is in contact with the top of the PET heat shrink film. When the electric rotating shaft 41 is started, the electric rotating shaft 41 drives the roller 42 to rotate, and the roller 42 drives the PET heat shrink film to automatically coat the material, thus simplifying the coating process. When the PET heat shrink film is running, it contacts the bottom of the dust removal plate 43 to scrape off the dust on the surface of the PET heat shrink film.

[0030] The anti-wrinkle device 4 also includes a rotating column 44, an adhesion wheel 45, a throbbing plate 46, and a telescopic rod 47. The back of the rotating column 44 is rotatably mounted on the front of the fixed plate 2. The adhesion wheel 45 is internally fixedly mounted on the outer wall surface of the rotating column 44, and a circular groove is formed on the outer wall of the adhesion wheel 45. The bottom of the throbbing plate 46 is fixedly mounted on the inner wall of the circular groove of the adhesion wheel 45, and the arc surface of the throbbing plate 46 contacts the top of the PET heat shrink film. The bottom of the telescopic rod 47 is fixedly mounted on the concave surface of the outer wall of the adhesion wheel 45, and the top of the telescopic end of the telescopic rod 47 is fixedly connected to the bottom of the throbbing plate 46. A spring is provided at the telescopic end of the telescopic rod 47. 45 drives the rotating column 44 to rotate. When the PET heat shrink film rotates, it comes into contact with the outer wall of the adhesion wheel 45, generating frictional resistance that causes the adhesion wheel 45 to rotate. The adhesion wheel 45 drives the rotating column 44 to rotate. When the adhesion wheel 45 rotates, it expands the dust removal range and dust removal quality of the dust removal plate 43. The adhesion wheel 45 drives the agitator 46 to rotate. When the agitator 46 comes into contact with the PET heat shrink film, it causes friction. The agitator 46 shrinks and deforms due to the friction force. When the agitator 46 recovers through its own elasticity, it stretches the PET heat shrink film with tension, preventing the material from sticking to the PET heat shrink film during the lamination process.

[0031] The adsorption device 5 includes an electric slide rail 51, an adsorption component 52, and a collection bucket 53. The top of the electric slide rail 51 is fixedly installed on the top of the inner wall of the U-shaped plate 3. The outer wall of the adsorption component 52 is slidably installed inside the electric slide rail 51. The bottom of the collection bucket 53 is through and fixedly installed on the top of the adsorption component 52, and the bottom of the collection bucket 53 is provided with filter holes. When the electric slide rail 51 is activated, the electric slide rail 51 drives the adsorption component 52 to slide left and right to adsorb flying dust. The adsorption component 52 drives the collection bucket 53 to move synchronously. The collection bucket 53 collects the dust sucked up by the adsorption component 52, which is convenient for staff to clean.

[0032] The adsorption device 5 also includes an electric rotating rod 54, a round rod 55, a convex ball block 56, and a reset plate 57. The bottom of the electric rotating rod 54 is rotatably mounted at the center of the bottom of the inner wall of the collection tank 53, and an arc-shaped groove is opened on the outer wall of the electric rotating rod 54. The right side of the round rod 55 is fixedly mounted on the left side of the outer wall of the electric rotating rod 54. The convex ball block 56 is internally penetrated and rotatably mounted on the surface of the outer wall of the round rod 55, and the outer wall of the convex ball block 56 is in contact with the inner wall of the filter holes. The front side of the reset plate 57 is fixedly mounted on the back side of the outer wall of the round rod 55. When the electric rotating rod is started... The electric rotating rod 54 drives the round rod 55 to rotate, and the round rod 55 drives the convex ball block 56 to rotate. The convex ball block 56 rotates and agitates the dust inside the collection bucket 53, causing the dust to be evenly distributed inside the collection bucket 53. When the convex ball block 56 comes into contact with the filter hole, it generates resistance and begins to rotate. When the convex ball block 56 rotates, it removes the sticky dust adhering to the inner wall of the filter hole of the collection bucket 53. The round rod 55 drives the reset plate 57 to rotate, and the reset plate 57 contacts and removes the solidified dirt adhering to the bottom of the inner wall of the collection bucket 53.

[0033] In use, when PET heat shrink film is needed to coat materials, the electric rotating shaft 41 is activated. The electric rotating shaft 41 drives the roller 42 to rotate, and the roller 42 drives the PET heat shrink film to automatically coat the materials, simplifying the coating process. When the PET heat shrink film is in operation, it contacts the bottom of the dust removal plate 43 to scrape away dust on the surface of the PET heat shrink film, ensuring its cleanliness. When the PET heat shrink film is in operation, it contacts the outer wall of the adhesion wheel 45, generating frictional resistance that causes the adhesion wheel 45 to rotate. The adhesion wheel 45 drives the rotating column 44 to rotate. The rotation of the adhesion wheel 45 expands the dust removal range and quality of the dust removal plate 43, further preventing dust from adhering to the outer wall of the PET heat shrink film. Simultaneously, through… The rotation of the adhesion wheel 45 makes the PET heat shrink film flatter during lamination, avoiding wrinkles. The adhesion wheel 45 drives the drum plate 46 to rotate. When the drum plate 46 comes into contact with the PET heat shrink film, it resists and shrinks due to the resistance force. When the drum plate 46 deforms, it squeezes the telescopic rod 47 to deform synchronously. The telescopic end of the telescopic rod 47 provides good support for the drum plate 46 through the elastic force of the spring, preventing the drum plate 46 from being over-deformed and difficult to recover in time. When the drum plate 46 recovers through its own elasticity, it stretches the PET heat shrink film with tension, avoiding mutual adhesion between the material and the PET heat shrink film during the lamination process, ensuring the neatness of the coverage, reducing manual intervention by workers, and further simplifying the workflow.

[0034] When the dust removal plate 43 and the adhesion wheel 45 are working, the electric slide rail 51 is activated. The electric slide rail 51 drives the adsorption component 52 to slide left and right to adsorb flying dust, expanding the adsorption range of the adsorption component 52. The adsorption component 52 drives the collection bucket 53 to move synchronously, and the collection bucket 53 collects the dust sucked up by the adsorption component 52 for easy cleaning by staff. The electric rotating rod 54 is activated, which drives the round rod 55 to rotate. The round rod 55 drives the convex ball block 56 to rotate, and the convex ball block 56 rotates and agitates the dust inside the collection bucket 53, causing the dust to settle in the collection bucket 53. The internal distribution is uniform to avoid reducing the volume of the collection bucket 53; when the convex ball 56 comes into contact with the filter hole, it generates resistance and begins to rotate. When the convex ball 56 rotates, it removes the sticky dust adhering to the inner wall of the filter hole of the collection bucket 53, preventing the dust from adhering and solidifying for a long time and clogging the filter hole, and preventing the dust from having difficulty entering the interior of the collection bucket 53; the round rod 55 drives the reset plate 57 to rotate, and the reset plate 57 comes into contact with the solidified dirt adhering to the bottom of the inner wall of the collection bucket 53. The reset plate 57 deforms through the contact force, and the electric rotating rod 54 continuously outputs force to the reset plate 57, causing the reset plate 57 to store force and bounce, improving the removal effect of the firmly attached dirt.

The right side of the telescopic shovel 77 is fixedly installed at the left side of the sliding plate 76, and the telescopic end of the telescopic shovel 77 is provided with a spring. When the swing plate 73 swings, it drives the torsion plate 74 to deform and return to its original shape. The torsion plate 74 drives the striking column 75 to repeatedly strike the bottom of the swing plate 73 to generate vibration. The swing plate 73 uses vibration force to irregularly beat the dust. The torsion plate 74 drives the sliding plate 76 to slide left and right along the bottom of the swing plate 73. When the sliding plate 76 slides, it agitates the dirt attached to the bottom of the swing plate 73 to prevent the dust from adhering and accumulating. The telescopic shovel plate 77 stores force to shovel the solidified material at the bottom of the swing plate 73 to prevent the solidified material generated during equipment operation from being corrosive.

[0040] In use, when the electric rotating rod 54 rotates, the arc groove restricts the connecting rod 61, enabling the connecting rod 61 to move up and down. The connecting rod 61 drives the heating ring 62 to slide synchronously along the inner wall of the collection bucket 53. The heating ring 62 scrapes the inner wall of the collection bucket 53 to reduce dirt adhesion. Heating the inside of the collection bucket 53 prevents dust contaminated with equipment oil from being corroded by moisture and growing mold during rainy weather, ensuring that the inside of the collection bucket 53 is dry. The heating ring 62 squeezes the central arc plate 63 and deforms synchronously to restore its original shape. The central arc plate 63 pushes the dust in the center, reducing the adhesion area of ​​the dust to the inner wall of the collection bucket 53. The central arc plate 63 drives the U-shaped pull plate 64 to move left and right. The U-shaped pull plate 64 pulls the purification bag 6. 5. Synchronous deformation generates spray force, and the purification bladder 65 sprays the purifying agent into the collection tank 53 through the spray gun 66, purifying the oily and damp bacteria that grow inside the collection tank 53. This prevents maintenance personnel from ingesting the bacteria during cleaning and thus avoids harm to their health, effectively providing a safe working environment for the staff. The U-shaped pull plate 64 drives the L-shaped baffle 67 to move synchronously. When the L-shaped baffle 67 moves towards the center of the collection tank 53, it disengages from blocking the spray gun 66, allowing the purifying agent to be sprayed out normally. When the L-shaped baffle 67 returns to its original position, it blocks the nozzle of the spray gun 66, preventing external dirt from entering the purification bladder 65 and contaminating the purifying agent, thus preventing a reduction in the purification effect.

[0041] When the adsorption component 52 slides left and right, it squeezes the elastic plate 71 to deform and return to its original shape. The elastic plate 71 drives the U-shaped pressure roller 72 to move up and down. When the U-shaped pressure roller 72 moves downward, it bends downward at the right edge of the swing plate 73. The pressure roller rotates due to downward pressure and friction, thereby improving the passage of the swing plate 73. When the swing plate 73 returns to its original shape due to its own elasticity, it swings up and down repeatedly. The swing plate 73 beats the flying dust attracted by the adsorption component 52 to prevent the adsorption component 52 from not absorbing enough dust and causing secondary adhesion to the PET heat shrink film. When the swing plate 73 swings, it drives the torsion piece 74 to deform and return to its original shape. The torsion piece 74 drives the striking column 75 to repeatedly strike the bottom of the swing plate 73 to generate dust. The vibration and oscillation plate 73 irregularly beats the dust with vibration force, further preventing the dust from causing secondary adhesion to the PET heat shrink film. At the same time, the torsion plate 74 drives the slide plate 76 to slide left and right along the bottom of the oscillation plate 73. When the slide plate 76 slides, it agitates the dirt attached to the bottom of the oscillation plate 73, preventing the dust from adhering and agglomerating and reducing the beating effect of the oscillation plate 73. The slide plate 76 drives the telescopic shovel plate 77 to move synchronously. The telescopic shovel plate 77 stores force and shovels the solidified material at the bottom of the oscillation plate 73, preventing the solidified material generated during equipment operation from being corrosive, preventing the outer wall of the oscillation plate 73 from being corroded and pitted, and extending the maintenance cycle of the oscillation plate 73 and other components.
