Description

Technical Field

[0001] This application relates to the field of release film processing, and more specifically, to a release film preparation oven. Background Technology

[0002] Release film refers to a thin film with a separable surface. When in contact with the film material under limited conditions, the release film has no adhesiveness or only slight adhesiveness, effectively protecting the film material. Release film is widely used in electronics, automotive foam, printing and other fields. Its application is mostly with adhesive materials, especially adhesive tape products. During the production of release film, it needs to be dried to increase the stability of the bond between the different layers of the release film.

[0003] In existing release film preparation ovens, the base film easily absorbs moisture during storage and unwinding (and the higher the ambient humidity, the more obvious the absorption phenomenon). It may also be contaminated with impurities such as dust, debris, and release agent particles. If the device does not pre-treat these impurities and excess moisture, on the one hand, the excessive moisture residue will cause the release film to be not completely dried before being wound up in the oven, thus affecting the drying quality; on the other hand, the impurities that are not cleaned on the film will be rolled into the forming film cylinder layer by layer during the winding process, ultimately affecting the overall quality of the release film. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a release film preparation oven. This oven solves the problem that in existing technologies, the base film easily absorbs moisture during storage and unwinding (and the higher the ambient humidity, the more obvious the absorption phenomenon). It may also be contaminated with impurities such as dust, debris, and release agent particles. If the device does not pre-treat these impurities and excess moisture, on the one hand, excessive moisture residue will cause the release film to be not completely dried before being wound up in the oven, thus affecting the drying quality. On the other hand, the impurities that are not cleaned on the film will be rolled into the forming film cylinder layer by layer during the winding process, ultimately affecting the overall quality of the release film.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An oven for preparing release film includes: an oven body, a door at the front end of the oven body, a winding and drying mechanism inside the oven body, a pre-cleaning mechanism on one side of the oven body, the pre-cleaning mechanism including a side mounting frame, the side mounting frame being disposed on one side of the oven body, a cleaning component being installed in the middle of the side mounting frame, a support side plate being fixedly disposed on one side of the oven body below the side mounting frame, and a collection box being disposed above the support side plate.

[0008] Furthermore, the cleaning assembly includes a servo motor, which is mounted on the upper side of the side mounting frame. The output end of the servo motor is connected to a positive and negative lead screw, and lead screw sleeves are screwed on both sides of the middle of the positive and negative lead screws. A scraper is fixed to the inner side of a pair of lead screw sleeves, and a guide sleeve is fixed to the other end of the pair of scrapers. A guide rod is fixed to the other side of the middle of the side mounting frame. A side guide groove is provided on the same side below the scraper and the side mounting frame. Lead screw protective covers are provided at both ends of the pair of guide sleeves and lead screw sleeves.

[0009] Furthermore, the guide rod is connected to the guide sleeve at one end of the scraper by a lifting guide assembly.

[0010] Furthermore, there are two scraper frames arranged opposite each other, and the two scraper frames are connected by positive and negative lead screws and lead screw sleeves to form a relative displacement connection.

[0011] Furthermore, the winding and drying mechanism includes a winding assembly, which is disposed on one side of the interior of the oven body. A guide roller is disposed on the other side of the interior of the oven body, and a tension roller is disposed at the lower section of the interior of the oven body.

[0012] Furthermore, the winding assembly includes a winding motor, which is mounted on the outer side of the oven body. The output end of the winding motor is connected to a winding roller. A fixing frame is fixedly provided on one side inside the oven body, and a reinforced support bearing is installed in the middle of the fixing frame. Guide edges are provided around the winding roller, and an outer sleeve is fitted around the winding roller. Guide grooves are provided on the inner side of the outer sleeve. Threaded grooves are provided around the same end of the outer sleeve and the winding roller, and a locking screw is threaded into the middle of the threaded groove.

[0013] Furthermore, the outer casing cylinder utilizes guide grooves and guide edges to form an alignment guide connection with the take-up roller.

[0014] The beneficial effects of this application are as follows:

[0015] Before the release film passes through the middle of the side mounting frame and is wound up, the operator can adjust the spacing of a pair of scrapers according to the thickness of the release film. The specific adjustment method is as follows: the operator starts the servo motor to rotate the positive and negative lead screws. At this time, the pair of lead screw sleeves that work with the positive and negative lead screws will carry their respective fixed scrapers and adjust their alignment under the guidance of the guide rod and guide sleeve. This allows the scraping surfaces of the pair of scrapers to fit tightly against the upper and lower surfaces of the release film. In this way, when the release film enters the winding stage, the tightly fitted pair of scrapers can effectively scrape off excess moisture and impurities from the film surface, thereby ensuring the high efficiency of drying of the release film in the main body of the drying oven. The scraped moisture and impurities will flow into the collection box along the side guide groove for centralized collection. The operator can then clean the contents of the collection box periodically.

[0016] The release film to be processed passes sequentially through the side mounting frame, guide roller, tension roller, and take-up roller. During operation, the operator can start the take-up motor to drive the take-up roller to rotate. During this process, the guide roller guides the direction of film transmission, while the tension roller maintains the constant tension of the film. The two work together to drive the release film to stretch and move at a uniform speed inside the oven. At this time, the drying components inside the oven can dry the release film. After the outer casing around the take-up roller has finished drying, receiving, and winding the release film, the operator can first remove the three locking screws used to lock the take-up roller and the outer casing. Then, with the guidance of the guide edge and guide groove, the outer casing of the wound release film can be removed, and a new outer casing can be installed to continue the operation.

[0029] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1-4As shown, this utility model provides a release film preparation oven, including: an oven body 1, a door 2 at the front end of the oven body 1, a winding and drying mechanism 3 installed inside the oven body 1, a pre-cleaning mechanism 4 on one side of the oven body 1, the winding and drying mechanism 3 including a winding assembly 31, the winding assembly 31 being disposed inside the oven body 1, the winding assembly 31 including a winding motor 311, the winding motor 311 being installed outside the oven body 1, and the output end of the winding motor 311 being connected to... The oven body 1 includes a take-up roller 312. A fixed frame 313 is fixedly mounted on one side of the oven body 1, and a reinforced support bearing 314 is installed in the middle of the fixed frame 313. Guide edges 315 are distributed around the periphery of the take-up roller 312, and an outer sleeve 316 is fitted around the outside of the take-up roller 312. Guide grooves 317 are distributed on the inner edge of the outer sleeve 316. Threaded grooves 318 are distributed around the same end of the outer sleeve 316 and the take-up roller 312, and a locking screw 319 is threaded into the middle of the threaded groove 318. The outer sleeve 316 utilizes the guide grooves 317 and... The guide edge 315 and the take-up roller 312 form a positioning guide connection. A guide roller 32 is provided on the other side of the interior of the oven body 1, and a tension roller 33 is provided at the lower section of the interior of the oven body 1. The release film to be processed will sequentially pass through the side mounting frame 41, the guide roller 32, the tension roller 33, and the take-up roller 312. During use, the operator can start the take-up motor 311 to drive the take-up roller 312 to rotate. During this process, the guide roller 32 guides the film's transport direction, while the tension roller 33 maintains the film's constant tension. The two work together to drive the release film... The release film moves at a constant speed inside the oven body 1. At this time, the drying components inside the oven body 1 can dry the release film. After the outer sleeve 316 around the take-up roller 312 has finished drying, receiving and winding the release film, the operator can first remove the three locking screws 319 used to lock the take-up roller 312 and the outer sleeve 316. Then, with the guidance of the guide edge 315 and the guide groove 317, the outer sleeve 316 with the wound release film can be removed, and a new outer sleeve can be replaced to continue the operation.

[0031] The pre-cleaning mechanism 4 includes a side mounting frame 41, which is located on one side of the oven body 1. A cleaning component 42 is mounted in the middle of the side mounting frame 41. The cleaning component 42 includes a servo motor 421, which is mounted on the upper side of the side mounting frame 41. The output end of the servo motor 421 is connected to a positive and negative lead screw 422. Lead screw sleeves 423 are screwed on both sides of the middle of the positive and negative lead screws 422. A scraper 424 is fixed inside the pair of lead screw sleeves 423. Two scrapers 424 are arranged opposite each other. Furthermore, the two scraper frames 424 are connected by positive and negative lead screws 422 and lead screw sleeves 423 to form a relative displacement connection. A guide sleeve 426 is fixed to one end of each scraper frame 424. A guide rod 425 is fixed to the other side of the middle section of the side mounting frame 41. A side guide groove 427 is provided on the same side of the lower scraper frame 424 and the side mounting frame 41. Lead screw protective covers 428 are provided at both ends of each of the guide sleeves 426 and the lead screw sleeve 423. The guide rod 425 is connected to the guide sleeve 426 at one end of the scraper frame 424 by a lifting guide connection. (Oven body) A support plate 43 is fixedly installed below the side mounting frame 41 on one side, and a collection box 44 is placed above the support plate 43. Before the release film passes through the middle of the side mounting frame 41 and is wound up, the operator can adjust the spacing of a pair of scraper frames 424 according to the thickness of the release film. The specific adjustment method is as follows: the operator starts the servo motor 421 to rotate the positive and negative lead screws 422. At this time, the pair of lead screw sleeves 423 that cooperate with the positive and negative lead screws 422 will carry their respective fixed scraper frames 424 between the guide rod 425 and the guide sleeve 426. Under the guidance of the guide, the alignment is adjusted so that the scraping surfaces of the pair of scrapers 424 are in close contact with the upper and lower surfaces of the release film. In this way, when the release film enters the winding stage, the closely attached pair of scrapers 424 can effectively scrape off excess moisture and impurities from the film surface, thereby ensuring the high efficiency of drying of the release film in the oven body 1. The scraped moisture and impurities will flow into the collection box 44 along the guide groove 427 for centralized collection. The collection box 44 can be cleaned periodically by the personnel.

[0032] Working Principle: In this release film preparation oven, the release film to be processed passes sequentially through the side mounting frame 41, guide roller 32, tension roller 33, and take-up roller 312. During operation, the operator starts the take-up motor 311 to rotate the take-up roller 312. During this process, the guide roller 32 guides the film's transport direction, while the tension roller 33 maintains constant film tension. Together, they drive the release film to move at a uniform speed within the oven body 1. The drying components inside the oven body 1 then dry the release film. After the outer mounting cylinder 316 around the take-up roller 312 has finished drying, receiving, and winding the release film, the operator can first remove the three locking screws 319 used to lock the take-up roller 312 and the outer mounting cylinder 316. Then, with the guidance of the guide edge 315 and guide groove 317, the outer mounting cylinder 316 with the wound release film can be removed, and a new outer mounting cylinder can be installed to continue the operation. Before the release film passes through the middle of the side mounting frame 41 and is wound up, the operator can adjust the spacing of a pair of scrapers 424 according to the thickness of the release film. The specific adjustment method is as follows: the operator starts the servo motor 421 to rotate the positive and negative lead screws 422. At this time, the pair of lead screw sleeves 423 that cooperate with the positive and negative lead screws 422 will carry their respective fixed scrapers 424 and adjust their alignment under the guidance of the guide rod 425 and the guide sleeve 426. This allows the scraping surfaces of the pair of scrapers 424 to be in close contact with the upper and lower surfaces of the release film. In this way, when the release film enters the winding stage, the closely attached pair of scrapers 424 can effectively scrape off excess moisture and impurities from the film surface, thereby ensuring the high efficiency of drying of the release film in the oven body 1. The scraped moisture and impurities will flow into the collection box 44 along the side guide groove 427 for centralized collection. The operator can then clean the contents of the collection box 44 periodically.
