Description

Technical Field

[0001] The present invention belongs to the technical field of PET film surface treatment equipment, and particularly relates to an intelligent oiling device for PET film surface treatment. Background Art

[0002] The intelligent oiling device for PET film surface treatment coats a layer of silicone oil on the surface of the PET film to reduce the adhesion on the surface of the PET film, achieving a release effect, thereby forming a PET release film. The PET release film is also called a PET silicone oil film. The PET release film has now been widely applied in industries such as packaging, printing, screen printing, pad printing, nameplates, membrane switches, flexible circuits, insulation products, circuit boards, laser anti-counterfeiting, lamination, electronics, films for sealing materials, reflective materials, waterproof materials, medicine (paper for medical ointments), toilet paper, adhesive products, die-cutting and stamping processing, etc.

[0003] Currently, the intelligent oiling device for PET film surface treatment mainly performs coating by roll coating. Roll coating is a common oiling method. Its basic principle is that the rotation of the oiling roll drives the silicone oil, the amount of silicone oil transfer is adjusted through the gap of the doctor blade, and the rotation of the oiling roll is used to transfer the silicone oil to the substrate. During roll coating, the rotation of the oiling roll drives the silicone oil to form a silicone oil layer with a certain thickness through the gap of the metering roll. When the PET film passes through this gap, the silicone oil layer adheres to its surface to complete the oiling.

[0004] When using an oiling roll for oiling, the situation of uneven oiling may occur. Since the existing doctor blade is fixedly installed outside the oiling roll, its position and angle are not adjustable. When a thicker coating is required, if the doctor blade is too close to the oiling roll, it is easy to scrape away the required coating, resulting in unqualified products. When a thinner coating is required, if the doctor blade is too far away, it is difficult to scrape off the excess coating, and the uniformity of the coating outside the oiling roll cannot be guaranteed either, which will also lead to unqualified products. At the same time, during the production process of PET release film, since the silicone oil contains solvents, these solvents need to be volatilized in subsequent steps to ensure the drying and adhesion of the silicone oil coated on the PET film. Currently, the cooling of the PET film after heating mainly uses air cooling. Although air cooling can quickly reduce the temperature on the surface of the PET film and contribute to the curing of the silicone oil, if the wind speed is too high during the air cooling process, it may cause certain stress on the PET release film, thereby causing jitter or deformation, further reducing its production quality.

[0005] Therefore, it is particularly important to urgently design an intelligent oiling device for PET film surface treatment to solve the above defects. Summary of the Invention

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an intelligent oiling device for PET film surface treatment, which aims to solve the technical problems that when the PET film surface is oiled in the prior art, the position and angle of the scraper on the outer side of the oiling roller cannot be adjusted, the uniformity of the paint on the outer side of the oiling roller cannot be guaranteed, resulting in unqualified products, and the shaking or deformation caused by the air-cooling cooling method will reduce the production quality.

[0008] (2) Technical solution

[0009] To solve the above technical problems, the present invention provides such an intelligent oiling device for PET film surface treatment, which includes an oiling frame. The inner side of the oiling frame is rotatably connected with an oiling roller. A storage oil box is installed below the oiling roller. A lifting mechanism is installed below the storage oil box. The left and right ends of the oiling frame and above the oiling roller are both slidably connected with adjusting frames. A guide roller and a metering roller are respectively rotatably connected between the two groups of adjusting frames. A scraping component is installed on the inner side of the oiling frame and on the back of the oiling roller. A heating cover is fixedly installed on the front of the oiling frame, and a cooling box is fixedly installed on the front of the heating cover;

[0010] The scraping component includes sliding seats slidably connected to the left and right ends of the back of the oiling frame. A connecting rod is fixedly installed at the top between the two groups of sliding seats. Installation frames are fixedly installed at the left and right ends of the connecting rod. The inner sides of the two groups of installation frames are rotatably connected with first oil cylinders. The outputs of the two groups of first oil cylinders are rotatably connected with adjusting seats, and the bottom ends of the two groups of adjusting seats are rotatably connected with the connecting rod. The top ends of the two groups of adjusting seats are both threadedly connected with adjusting screws. An adjusting plate is installed between the two groups of adjusting screws, and the front ends of the two groups of adjusting screws are rotatably connected with the adjusting plate. A scraper is fixedly installed at the front end of the adjusting plate and on the outer side of the oiling roller.

[0011] When using the equipment of the present technical solution, the PET film is introduced from the back of the oil coating rack, and then the PET film is S-shaped and passes around the guide roller and the metering roller in turn, and finally passes between the metering roller and the oil coating roller. When the oil coating roller rotates, it adheres to the silicone oil inside the oil storage box for oiling. By adjusting the height of the adjustment rack, the distance between the metering roller and the oil coating roller can be adjusted to ensure the thickness of the silicone oil coated on the surface of the PET film.

After the silicone oil is coated on the surface of the PET film, it is removed from the oil coating rack. The PET film is guided out from the front side of the heating cover, then passes through the front end of the heating cover and goes around the outside of the winding roller in a "J" shape, and finally goes out from the front side of the heating cover, so that the PET film is fully heated between the winding roller and the heating tube, the volatilization of the solvent is accelerated, and the silicone oil is quickly dried.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Through the cooperative design of the oiling rack, oiling rollers, oil storage box and lifting mechanism in the equipment of the present invention, the oiling rollers can be quickly disassembled and assembled from the inside of the oiling rack, which is convenient for disassembling, assembling and maintaining the oiling rollers. By using the lifting mechanism to adjust the height of the oil storage box, the contact area between the silicone oil in the oil storage box and the oiling rollers can be adjusted. At the same time, the oil storage box can be lowered to facilitate adding silicone oil and cleaning its interior, further improving the use convenience of the equipment.

[0024] 2. Through the design of the scraping component, when the PET film is oiled on the surface, the PET film is introduced from the back of the oiling rack. Subsequently, the PET film bypasses the guide roller and the metering roller in an S shape, and finally passes through between the metering roller and the oiling roller. When the oiling roller rotates, silicone oil inside the oil storage box adheres to it for the oiling operation. By adjusting the height of the adjusting frame, the distance between the metering roller and the oiling roller can be adjusted, thereby ensuring the thickness of the silicone oil coated on the surface of the PET film. At this time, when the two groups of adjusting screws are rotated simultaneously, the position of the adjusting plate can be adjusted, and the distance between the scraper and the oiling roller can be adjusted according to the oiling thickness. At the same time, starting the first oil cylinder can drive the adjusting seat to rotate outside the connecting rod, and then the angle of the scraper can be adjusted, so that the scraper can meet different processing requirements and ensure the oiling quality of the PET film.

[0025] 3. Through the combined design of the heating cover and the cooling box, after the silicone oil is coated on the surface of the PET film, it is exported from the front of the oiling rack. Subsequently, it enters the inside of the heating cover from the front end of the heating cover, bypasses the outside of the winding roller in a "Ji" shape, and finally exits from the front of the heating cover, so that the PET film is fully heated between the winding roller and the heating tube, accelerating the volatilization of the solvent and quickly drying the silicone oil. After the PET film is heated by the heating cover, it enters the cooling box, and then bypasses the first cooling plate and the second cooling plate in a Z shape. The cooling water in the cooling box is introduced into the second cooling plate, and the first cooling plate and the second cooling plate are connected by multiple groups of connecting pipes, so that the PET film can be quickly cooled down after contacting the first cooling plate and the second cooling plate. Compared with the existing air-cooled heat dissipation method, it not only has higher efficiency, but also will not be affected by wind to cause jitter or deformation, improving the production efficiency and production quality of the PET film.

An oiling roller 2 is rotatably connected to the inner side of the oiling rack 1. An oil storage box 3 is installed below the oiling roller 2. A lifting mechanism 4 is installed below the oil storage box 3. Adjusting frames 5 are slidably connected to the left and right ends of the oiling rack 1 and above the oiling roller 2.

A scraping component 8 is installed on the inner side of the oiling rack 1 and on the back of the oiling roller 2. A heating cover 9 is fixedly installed on the front of the oiling rack 1. A cooling box 10 is fixedly installed on the front of the heating cover 9.

[0041] First, in this embodiment, the specific structure of the scraping component 8 is as follows:

[0042] The scraping component 8 includes sliding seats 801 slidably connected to the left and right ends of the back of the oiling rack 1. A connecting rod 802 is fixedly installed at the top between the two groups of sliding seats 801. Installation frames 803 are fixedly installed at the left and right ends of the connecting rod 802. A first oil cylinder 804 is rotatably connected to the inner side of each of the two groups of installation frames 803. An adjusting seat 805 is rotatably connected to the output of each of the two groups of first oil cylinders 804. And the bottom ends of the two groups of adjusting seats 805 are rotatably connected to the connecting rod 802. Adjusting screws 806 are threadedly connected to the top ends of the two groups of adjusting seats 805. An adjusting plate 807 is installed between the two groups of adjusting screws 806. And the front ends of the two groups of adjusting screws 806 are rotatably connected to the adjusting plate 807. A scraper 808 is fixedly installed at the front end of the adjusting plate 807 and outside the oiling roller 2. When performing oiling treatment on the PET film surface, the PET film is introduced from the back of the oiling rack 1, and then the PET film sequentially bypasses the guide roller 6 and the metering roller 7 in an S shape, and finally passes through between the metering roller 7 and the oiling roller 2. When the oiling roller 2 rotates, silicone oil inside the oil storage box 3 adheres to it for the oiling operation. By adjusting the height of the adjusting frame 5, the distance between the metering roller 7 and the oiling roller 2 can be adjusted, so as to ensure the thickness of the silicone oil coated on the PET film surface. At this time, rotating the two groups of adjusting screws 806 simultaneously can adjust the position of the adjusting plate 807, and the distance between the scraper 808 and the oiling roller 2 can be adjusted according to the oiling thickness. At the same time, starting the first oil cylinder 804 can drive the adjusting seat 805 to rotate outside the connecting rod 802, and then the angle of the scraper 808 can be adjusted, so that the scraper 808 can meet different processing requirements and ensure the oiling quality of the PET film.

[0043] Furthermore, the upper and lower ends of the two groups of sliding seats 801 are slidably connected to the oiling rack 1 through sliding rods 809. A second oil cylinder 810 is fixedly installed on the left side of the oiling rack 1, and the output end of the second oil cylinder 810 is connected to one of the sliding seats 801. The second oil cylinder 810 can push the sliding seat 801, so that the sliding seat 801 slides outside the sliding rod 809, thereby enabling left - right adjustment of the scraper 808, which is convenient for the scraper 808 to play a role in alignment with the oiling roller 2.

[0044] Then, the top of the back side of the oiling rack 1 is rotatably connected with two groups of entry rollers 101, the front end of the left side of the oiling rack 1 is fixedly installed with a first reduction motor 201, and the end of the oiling roller 2 located on the left side of the oiling rack 1 is fixedly installed with a first transmission gear 202, and the left side of the oiling rack 1 is rotatably connected with a second transmission gear 203, and the second transmission gear 203 is meshed with the first transmission gear 202, and the driving end of the first reduction motor 201 is transmission-connected with the second transmission gear 203 through a synchronous pulley set 204. When the surface of the PET film is oiled, the PET film passes through the two groups of entry rollers 101 and goes around the inner side of the oiling rack 1, and then the PET film is S-shaped and successively bypasses the guide roller 6 and the metering roller 7, and finally passes between the metering roller 7 and the oiling roller 2, and the first reduction motor 201 is started to drive the second transmission gear 203 to rotate through the synchronous pulley set 204, and then the oiling roller 2 is driven to rotate under the transmission of the first transmission gear 202, and when the oiling roller 2 rotates, it adheres to the silicone oil inside the oil storage box 3 for oiling operation.

[0045] Furthermore, both left and right ends of the oiling roller 2 are rotatably connected to the oiling frame 1 through bearings 205, and both left and right ends of the oiling frame 1 are provided with mounting grooves 206 at positions corresponding to the bearings 205, and a fixing seat 207 is installed inside the mounting groove 206 and outside the bearing 205, and a positioning plate 208 is movably installed on the front of the oiling frame 1 and outside the mounting groove 206, and the top of the positioning plate 208 is fixedly connected to the oiling frame 1 through screws, and the internal thread of the positioning plate 208 is connected with a positioning screw 20 9, and the rear end of the positioning screw 209 is rotatably connected to the fixing seat 207, and the oiling roller 2 can rotate on the inner side of the oiling rack 1 through the bearing 205. After fixing the positioning plate 208 with screws, the positioning screw 209 is rotated to move the fixing seat 207 backward, so that the outer ring of the bearing 205 is fixed by the fixing seat 207 to install the oiling roller 2 on the inner side of the oiling rack 1. Correspondingly, after unscrewing the screws and removing the positioning plate 208, the oiling roller 2 can also be quickly disassembled and assembled, thereby facilitating the disassembly and assembly and maintenance of the oiling roller 2.

[0046] Among them, the lifting mechanism 4 includes lifting racks 401 fixedly installed at the left and right ends of the bottom of the oil storage box 3. Transmission boxes 402 are fixedly installed on both the left and right sides inside the oiling rack 1 and below the oil storage box 3, and the lifting racks 401 extend into the interior of the transmission boxes 402. A linkage rod 403 is rotatably connected between the two transmission boxes 402, and both the left and right ends of the linkage rod 403 are engaged with the lifting racks 401 through linkage gears 404. A worm gear 405 is fixedly installed at the right end of the linkage rod 403 and outside the oiling rack 1. An operating shaft 406 is rotatably connected to the right side of the oiling rack 1, and the rear end of the operating shaft 406 is engaged with the worm gear 405 through a worm 407. By rotating the operating shaft 406, the linkage rod 403 is driven to rotate under the transmission of the worm 407 and the worm gear 405. Subsequently, under the transmission of the linkage gears 404, the lifting racks 401 are driven to move up and down inside the transmission boxes 402, thereby adjusting the height of the oil storage box 3, being able to adjust the contact area between the silicone oil in the oil storage box 3 and the oiling roller 2, and at the same time being able to lower the oil storage box 3 to facilitate the addition of silicone oil and the cleaning inside it, further improving the use convenience of the equipment.

[0047] Furthermore, third oil cylinders 501 are fixedly installed at the left and right ends of the top of the oiling rack 1, and the output ends of the two third oil cylinders 501 are fixedly connected to the top ends of the adjusting frames 5. The backs of the two adjusting frames 5 are slidably connected to the oiling rack 1 through guide rails 502. Starting the third oil cylinders 501 can adjust the height of the adjusting frames 5 under the connection of the guide rails 502, thereby being able to adjust the distance between the metering roller 7 and the oiling roller 2 according to the oiling thickness.

[0048] Moreover, the outside of the heating cover 9 is fixedly connected to the cooling box 10 through a connecting frame 901. Heating tubes 902 are fixedly installed on the inner side wall of the heating cover 9. A winding roller 903 is rotatably connected to the bottom end inside the connecting frame 901. A second reduction motor 904 is fixedly installed on the left side of the connecting frame 901, and the driving end of the second reduction motor 904 is fixedly connected to the left end of the winding roller 903. After the PET film is coated with silicone oil, it is led out from the front of the oiling rack 1, then wound into the inside of the heating cover 9 through the front end of the heating cover 9, bypasses the outside of the winding roller 903 in a "zigzag" shape and finally winds out from the front of the heating cover 9, so that the PET film is fully heated between the winding roller 903 and the heating tubes 902, accelerating the volatilization of the solvent and quickly drying the silicone oil.

[0049] Furthermore, a first cooling plate 1001 and a second cooling plate 1002 are respectively and fixedly installed at the upper and lower ends inside the cooling box 10. The first cooling plate 1001 and the second cooling plate 1002 are connected and communicated through multiple groups of connecting pipes 1003. A water cooling box 1004 is fixedly installed on the left side of the cooling box 10, and a radiator 1005 is fixedly installed on the left side of the water cooling box 1004. An inlet is provided at a position on the back of the cooling box 10 corresponding to the heating hood 9. The PET film enters the cooling box 10 after being heated by the heating hood 9, and then bypasses the first cooling plate 1001 and the second cooling plate 1002 in a Z shape. The cooling water in the cooling box 10 is introduced into the second cooling plate 1002, and the first cooling plate 1001 and the second cooling plate 1002 are connected and communicated through multiple groups of connecting pipes 1003, so that the PET film can be quickly cooled and temperature-reduced after contacting the first cooling plate 1001 and the second cooling plate 1002. Compared with the existing air-cooled heat dissipation method, it not only has higher cooling efficiency, but also will not be affected by wind force to cause jitter or deformation, thereby improving the production efficiency and production quality of the PET film.

[0050] Secondly, rotating cylinders 1006 are rotatably connected to the front and rear ends of both the first cooling plate 1001 and the second cooling plate 1002. Limiting plates 1007 are fixedly installed at the left and right ends of both the first cooling plate 1001 and the second cooling plate 1002. When the PET film bypasses the first cooling plate 1001 and the second cooling plate 1002, the rotating cylinders 1006 are used to avoid friction damage, and at the same time, the limiting plates 1007 are used to limit both ends of the PET film to prevent deviation.

[0051] Finally, cooling cavities are provided on the inner sides of the first cooling plate 1001 and the second cooling plate 1002. A first water pump 1008 is installed at one end between the water cooling box 1004 and the second cooling plate 1002, and a first water return pipe 1009 is installed at the other end between the water cooling box 1004 and the second cooling plate 1002. A second water pump 1010 is installed between the water cooling box 1004 and the radiator 1005, and a second water return pipe 1011 is installed between the bottom end of the radiator 1005 and the water cooling box 1004. The input end of the first water pump 1008 reaches directly to the bottom end inside the water cooling box 1004. The cooling water is sent into the second cooling plate 1002 through the first water pump 1008, and then is introduced into the first cooling plate 1001 through the connecting pipe 1003, so as to provide a cooling function for the first cooling plate 1001 and the second cooling plate 1002. At the same time, the heated water flows back into the water cooling box 1004 through the first water return pipe 1009 to form a water cycle, continuously ensuring the cooling effect. The input end of the second water pump 1010 also reaches directly to the bottom end inside the water cooling box 1004. The cooling water inside the water cooling box 1004 is continuously sent into the radiator 1005 through the second water pump 1010. The multi-group of heat dissipation fins on the outer side of the radiator 1005 quickly cool the cooling water, and then the cooled water is re-introduced into the water cooling box 1004 through the second water return pipe 1011, further continuously ensuring the cooling effect.

[0052] When using the device of this technical solution, during the oil coating treatment on the surface of the PET film, the PET film is introduced from the back of the oil coating rack 1, and then the PET film sequentially bypasses the guide roller 6 and the metering roller 7 in an S shape, and finally passes through between the metering roller 7 and the oil coating roller 2. When the oil coating roller 2 rotates, silicone oil inside the oil storage box 3 adheres to it for the oil coating operation. By adjusting the height of the adjusting frame 5, the distance between the metering roller 7 and the oil coating roller 2 can be adjusted, thereby ensuring the thickness of the silicone oil coated on the surface of the PET film. At this time, when rotating the two groups of adjusting screws 806 simultaneously, the position of the adjusting plate 807 can be adjusted, and the distance between the scraper 808 and the oil coating roller 2 can be adjusted according to the oil coating thickness. At the same time, starting the first oil cylinder 804 can drive the adjusting seat 805 to rotate outside the connecting rod 802, and then the angle of the scraper 808 can be adjusted, so that the scraper 808 can meet different processing requirements. After the silicone oil is coated on the surface of the PET film, it is exported from the front of the oil coating rack 1, and then enters the inner side of the heating hood 9 by bypassing the front end of the heating hood 9, bypasses the outside of the winding roller 903 in a "ji" shape and finally exits from the front of the heating hood 9, so that the PET film is fully heated between the winding roller 903 and the heating tube 902, accelerating the volatilization of the solvent and quickly drying the silicone oil. After the PET film is heat-treated by the heating hood 9, it enters the cooling box 10, and then bypasses the first cooling plate 1001 and the second cooling plate 1002 in a Z shape. The cooling water in the cooling box 10 is introduced into the second cooling plate 1002, and the first cooling plate 1001 and the second cooling plate 1002 are connected by multiple groups of connecting pipes 1003, so that the PET film can be quickly cooled down after contacting the first cooling plate 1001 and the second cooling plate 1002. Compared with the existing air-cooled heat dissipation method, it not only has higher efficiency, but also will not be affected by wind to cause jitter or deformation. The whole operation process is simple and convenient. The present invention can design to make the scraper 808 meet different processing requirements, ensure the oil coating quality of the PET film, accelerate the volatilization of the solvent, quickly dry the silicone oil, can quickly cool down, and improve the production efficiency and production quality of the PET film.

[0053] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
