Description

Technical Field

[0001] This invention belongs to the technical field of release membrane dust removal equipment, specifically relating to a release membrane dust removal device that is easy to clean. Background Technology

[0002] Release film, also known as release liner, is typically made by treating plastic films with plasma, coating them with fluorine, or applying silicone release agents to the surface of the film material to increase their release force. This allows the film to exhibit extremely light and stable release force against various organic pressure-sensitive adhesives. Release film is now widely used in packaging, printing, insulation products, sealing materials, reflective materials, waterproof materials, pharmaceuticals, sanitary paper, adhesive products, die-cutting and stamping processes, and other industries. After production, dust removal equipment is needed to remove dust adhering to the surface of the release film, eliminating floating dust and ensuring product quality, while also ensuring the smooth operation of subsequent roll forming.

[0003] Existing dust removal technologies typically utilize electrostatic adsorption. However, after prolonged use, the dust adhering to the electrostatic roller will re-adhere to the release film. Directly pressing the release film with the electrostatic roller for dust removal will affect the film. Furthermore, the electrostatic roller requires shutdown and cleaning after prolonged operation, which is time-consuming and inconvenient, resulting in low dust removal efficiency. Summary of the Invention

[0008] Furthermore, the centerline of the second roller is parallel to the centerline of the third roller, and the second roller is located above the third roller.

[0009] Furthermore, the cleaning mechanism comprises: a first fixed cylinder fixedly installed on a support frame, gel placed inside the first fixed cylinder, the open end of the first fixed cylinder in contact with a rubber belt, a first rotating shaft rotatably installed on the support frame, a second gear provided at one end of the first rotating shaft, the second gear being connected to the dust removal component via a chain, slots provided on the chain engaging with the second gear, a fourth pulley provided at the other end of the first rotating shaft, the fourth pulley being connected to the second pulley via a second belt, stirring rods located inside the first fixed cylinder being evenly arranged in the circumferential direction on the outer side wall of the first rotating shaft, and fixed rods being evenly arranged on the inner side wall of the first fixed cylinder, the fixed rods and stirring rods being staggered.

[0011] Furthermore, the film winding mechanism is as follows: a fifth rotating shaft is provided on the support frame, and a sixth pulley is provided at both ends of the fifth rotating shaft.

[0013] The beneficial effects of the present invention are as follows: (1) The present invention uses a release film through a first adsorption mechanism and a second adsorption mechanism. The first adsorption mechanism and the second adsorption mechanism simultaneously remove dust from the upper and lower surfaces of the release film. During the transportation of the release film, the dust on the release film will accumulate in the groove between the rubber belt and the electrostatic adsorption belt. The stirring rod and the fixing rod in the cleaning mechanism can knead the gel, and the gel can better clean the dust in the groove. The brush on the first slide can better clean the dust in the groove between the rubber belt and the electrostatic adsorption belt during the sliding process, which improves the dust removal efficiency of the release film. At the same time as removing dust, the dust on the first adsorption mechanism and the second adsorption mechanism can be cleaned, which avoids the dust on the first adsorption mechanism and the second adsorption mechanism from re-attaching to the release film; ( 2) In this invention, each fourth rotating shaft drives the second eccentric shaft to rotate eccentrically through the disc in sequence. Each second eccentric shaft slides vertically in the fourth groove of the slide bar. Each slide bar slides horizontally in the third groove of the second support plate. The two slide bars drive the second connecting rod to move horizontally. The two pressure plates on the second connecting rod flatten the two sides of the moving release film respectively to prevent the release film from curling up during the transmission process. (3) In this invention, the release film is wound on the fourth roller. When the release film wound on the fourth roller comes into contact with the contact plate, the contact plate comes into contact with the position sensor. The position sensor detects that the contact plate has reached the predetermined position. The position sensor converts the received information into an electrical signal and sends it to the controller. The controller controls the motor to shut down to prevent the fourth roller from winding too much material and causing an accident. Attached Figure Description

During the transportation process, the dust on the release film 7 will accumulate in the groove 202 between the rubber belt 201 and the electrostatic adsorption belt 203.

[0064] During the transmission process of the rubber belt 201 and the electrostatic adsorption belt 203, the gel in the first fixed cylinder 305 cleans the dust in the groove 202.

The fourth pulley 307 drives the first rotating shaft 303 to rotate, and the first rotating shaft 303 drives the stirring rod 306 to rotate. The stirring rod 306 and the fixed rod 308 can knead the gel, and the gel can better clean the dust.

[0065] The second gear 304 on the first rotating shaft 303 drives the chain 301 to rotate, the chain 301 drives the third gear 405 to rotate, the third gear 405 drives the second rotating shaft 406 to rotate, the second rotating shaft 406 drives the fifth gear 415 to rotate, the fifth gear 415 drives the fourth gear 413 to rotate, the fourth gear 413 drives the third rotating shaft 418 to rotate, the third rotating shaft 418 drives the first eccentric shafts 417 at both ends to rotate eccentrically, each first eccentric shaft 417 slides horizontally in the second groove 416 of the second slide plate 408, each second slide plate 408 slides vertically between the two second fixed plates 411, each second slide plate 408 drives the side plate 404 to slide horizontally on the second rotating shaft 406 through the first connecting rod 407, each side plate 404 drives the first slide plate 403 to slide horizontally in the first groove 410 of the first fixed plate 409, the brush 401 on the first slide plate 403 can better clean the dust in the groove 202 between the rubber belt 201 and the electrostatic adsorption belt 203 during the sliding process.

[0066] Flattening the release film: The first pulley 206 drives one of the fifth pulleys 501 to rotate via the first belt 209, and the third pulley 213 drives the other fifth pulley 501 to rotate via the third belt 214. The two fifth pulleys 501 drive the two fourth shafts 502 to rotate respectively. Each fourth shaft 502 drives the disc 506 to rotate. Each disc 506 drives the second eccentric shaft 513 to rotate eccentrically. Each second eccentric shaft 513 slides vertically in the fourth groove 512 of the slide rod 503. Each slide rod 503 slides horizontally in the third groove 508 of the second support plate 507. The two slide rods 503 drive the second connecting rod 505 to move horizontally. The two pressure plates 504 on the second connecting rod 505 flatten the two sides of the moving release film 7 to prevent the release film 7 from curling up during the transmission process.

[0067] Release film winding: During operation, the second adsorption mechanism drives the sixth pulley 604 to rotate via the fourth belt 603. The sixth pulley 604 drives the fifth rotating shaft 605 to rotate, and the fifth rotating shaft 605 drives the first turntable 606 to rotate. The locking rod 612 on the first turntable 606 engages with the locking hole 611 on the second turntable 607, causing the second turntable 607 to rotate. The second turntable 607 drives the fourth roller 608 to rotate, and the release film 7 is wound around the fourth roller 608. When the release film 7 wound around the fourth roller 608 comes into contact with the contact plate 602, the contact plate 602 comes into contact with the position sensor 601. The position sensor 601 detects that the contact plate 602 has reached the predetermined position and converts the received information into an electrical signal, which is sent to the controller. The controller controls the motor 208 to shut down, and the entire device stops working to prevent the fourth roller 608 from overwinding and causing an accident.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
