Description

Technical Field

[0001] This utility model relates to the field of television casing processing technology, and more specifically, to a packaging and film covering device for processing the back shell of a television. Background Technology

[0002] A television set is an electronic device used to receive television signals and convert them into visible images and sound. It typically consists of a display screen, speakers, and internal circuitry, and can play film and television programs obtained through various means such as antennas, satellite, cable television, or the internet. During television production, the back cover of the television set is packaged and laminated. This lamination is primarily for product protection, preventing damage from moisture, dust, and scratches during transportation and storage, while also reducing the impact of static electricity on electronic components. Furthermore, the lamination enhances the aesthetics of the packaging, facilitates identification and management, and ensures the product arrives at the consumer undamaged.

[0003] A search revealed that Chinese patent application number CN220447238U discloses a molding device for a protective film on a television casing. The molding device includes: a slide rail at the bottom of the molding device, a roller on the slide rail, a plastic film roll outside the roller, the plastic film roll collecting and winding plastic film, a cutting strip on one side of the molding device, a molding base and a molding top cover inside the molding device, and a telescopic device at the top of the molding device, the telescopic device being connected to a vacuum conduit.

[0004] Although the aforementioned patent uses a telescopic device to pre-place the vacuum conduit within the sealing base area and then activates it before the sealing process of the sealing top cover, effectively improving the lamination quality of subsequent products by extracting the gas between the two layers of plastic film, the following shortcomings still exist during use: 1. The plastic film roll of this device is not easy to disassemble and replace; 2. The method of laminating by repeatedly moving the plastic film roll is cumbersome and has low lamination efficiency.

[0005] Therefore, there is an urgent need for a packaging and film coating device for processing the back cover of a television set to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a packaging and film coating device for processing the back cover of a television set, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A packaging and film-coating device for processing the back cover of a television set includes a base, symmetrically distributed support columns fixedly connected to the outer wall of the base, a shelf fixedly connected to the end of each support column away from the base, symmetrically distributed first strong springs fixedly connected to the inner wall of the base, and a placement plate fixedly connected to the end of each first strong spring away from the base; the device also includes:

[0009] A connecting plate is fixedly connected to the outer wall of the base, and a drive motor is fixedly connected to the end of the connecting plate away from the base.

[0010] A coating assembly includes a main support symmetrically fixedly connected to the outer wall of a base, a secondary support fixedly connected to the outer wall of the main support, a drive rod rotatably connected to the inner wall of the secondary support, a pulley fixedly connected to the outer wall of the drive rod, the symmetrical pulleys being connected via a belt body for transmission, a rotating rod slidably connected to the outer wall of the drive rod, and the drive rod located on the left side being fixedly connected to the output end of a drive motor.

[0011] The components are designed for easy disassembly and are located on the outer wall of the base.

[0012] As a preferred technical solution of this application, the detachable component is symmetrically fixedly connected to the fixed bracket on the outer wall of the base. The outer wall of the fixed bracket is slidably connected to a slide rod, and the end of the slide rod away from the fixed bracket is fixedly connected to a movable bracket. The inner walls of the movable bracket, the fixed bracket, and the main bracket are all provided with symmetrically distributed rotating grooves. The outer wall of the slide rod is fitted with a second strong spring, and the second strong spring is fixedly connected to the fixed bracket. The end of the second strong spring away from the fixed bracket is fixedly connected to the slide rod.

[0013] As a preferred technical solution of this application, the outer wall of the rotating rod is fixedly connected with symmetrically distributed rotating blocks, and the rotating blocks are located on the inner wall of the rotating groove.

[0014] As a preferred technical solution of this application, the top wall of the shelf is provided with symmetrically distributed spare rollers, and the end of the shelf away from the support column is fixedly connected with symmetrically distributed support feet.

[0015] As a preferred technical solution of this application, a working frame is fixedly connected to the outer wall of the base, a hydraulic cylinder is fixedly connected to the end of the working frame away from the base, and a film-coating plate is fixedly connected to the output end of the hydraulic cylinder through the working frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. The movable bracket slides on the fixed bracket via a slide bar, and the second strong spring pushes the slide bar to make the movable bracket fit tightly against the fixed bracket and squeeze to install the rotating rod. This allows for flexible disassembly of the rotating rod, making it easy to disassemble and replace the plastic film roller. It has high flexibility and solves the problem that the plastic film roll is not easy to disassemble and replace in the prior art.

[0019] 2. By setting two rotating rods and installing two rollers, which are used for conveying and recycling plastic film respectively, the plastic film is squeezed and cut in the coating area by the coating plate during the conveying process. Multiple coatings can be performed without repeated movement, simplifying the operation steps and improving the coating efficiency. This solves the problem that the existing technology of coating by repeatedly moving the plastic film roll is cumbersome and has low coating efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1 As shown, this embodiment proposes a packaging and film-coating device for processing the back cover of a television set, including a base 1. Symmetrically distributed support columns 2 are fixedly connected to the outer wall of the base 1. A shelf 3 is fixedly connected to the end of each support column 2 away from the base 1. Symmetrically distributed first strong springs 8 are fixedly connected to the inner wall of the base 1. A placement plate 7 is fixedly connected to the end of each first strong spring 8 away from the base 1. When the film-coating plate 12 presses against the back cover of the television set, the back cover is subjected to pressure, which in turn presses against the placement plate 7 and the first strong springs 8, causing them to contract and deform. Simultaneously, the first strong springs 8 exert a reaction force on the placement plate 7, thereby achieving a slow descent and preventing excessive pressure from damaging the back cover of the television set. The device also includes:

[0029] A connecting plate 6 is fixedly connected to the outer wall of the base 1, and a drive motor 9 is fixedly connected to the end of the connecting plate 6 away from the base 1.

[0030] The coating assembly includes a main support 13 symmetrically fixedly connected to the outer wall of the base 1. A secondary support 14 is fixedly connected to the outer wall of the main support 13. A drive rod 15 is rotatably connected to the inner wall of the secondary support 14. A pulley 16 is fixedly connected to the outer wall of the drive rod 15. The symmetrical pulleys 16 are connected via a belt body 17. A rotating rod 18 is slidably connected to the outer wall of the drive rod 15. The drive rod 15 on the left side is fixedly connected to the output end of the drive motor 9. When the drive motor 9 is started, the drive rod 15 connected to the output end of the drive motor 9 rotates through the output end of the drive motor 9, thereby driving the belt. Wheel 16 rotates and drives the other pulley 16 through belt body 17, thereby achieving synchronous rotation of drive rods 15 on both sides. Furthermore, the drive rod 15 and the rotating rod 18 are slidably nested, so the rotation of the drive rod 15 drives the rotating rod 18 to rotate. Since the rotating rod 18 rotates in the rotating groove 23 through the rotating block 24, it cannot be displaced. Thus, the rotating rod 18 drives the coating roller (not shown in the figure) installed on the rotating rod 18 to rotate. The coating roller on one side releases unused film, and the coating roller on the other side recycles and wraps the used film.

[0031] The components are designed for easy disassembly and are located on the outer wall of the base 1.

[0032] like Figure 5As shown, in a preferred embodiment, based on the above method, a further step is to detach the component and fix the bracket 21 symmetrically fixed to the outer wall of the base 1. The outer wall of the fixed bracket 21 is slidably connected to the slide rod 20, and the end of the slide rod 20 away from the fixed bracket 21 is fixedly connected to the movable bracket 19. The inner walls of the movable bracket 19, the fixed bracket 21 and the main bracket 13 are all provided with symmetrically distributed rotating grooves 23. The outer wall of the slide rod 20 is fitted with a second strong spring 22, and the second strong spring 22 is fixedly connected to the fixed bracket 21. The end of the second strong spring 22 away from the fixed bracket 21 is fixedly connected to the slide rod 20. Pulling the movable bracket 19 and sliding it on the fixed bracket 21 through the slide rod 20, while the slide rod 20 compresses the second strong spring 22, at which point the rotating rod 18 and the coating roller can be detached.

[0033] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the outer wall of the rotating rod 18 is further provided with symmetrically distributed rotating blocks 24, and the rotating blocks 24 are located on the inner wall of the rotating groove 23. The rotating rod 18 rotates in the rotating groove 23 through the rotating blocks 24, and can be disassembled. The rotating blocks 24 are used for limiting the rotation.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, the top wall of the shelf 3 is further provided with symmetrically distributed spare rollers 5, and the end of the shelf 3 away from the support column 2 is fixedly connected with symmetrically distributed support feet 4, so that the spare rollers 5 can be replaced at any time, reducing the time to take out new coating rollers.

[0035] like Figure 2 As shown, in a preferred embodiment, based on the above method, a work frame 10 is fixedly connected to the outer wall of the base 1, and a hydraulic cylinder 11 is fixedly connected to the end of the work frame 10 away from the base 1. The output end of the hydraulic cylinder 11 passes through the work frame 10 and is fixedly connected to a film-coating plate 12. The film-coating operation on the back cover of the TV is achieved by squeezing the film through the film-coating plate 12.

[0036] Specifically, when using this packaging and laminating device for processing the back cover of a television set: First, place the back cover of the television set to be processed on the base 1. Then, start the drive motor 9. The output of the drive motor 9 drives the drive rod 15 connected to the output of the drive motor 9 to rotate, which in turn drives the pulley 16 to rotate. The pulley 16 on the other side is then driven by the belt body 17, thus achieving synchronous rotation of the drive rods 15 on both sides. Furthermore, the drive rod 15 and the rotating rod 18 are slidably nested, so the rotation of the drive rod 15 drives the rotating rod 18 to rotate. Since the rotating rod 18 rotates within the rotating groove 23 through the rotating block 24, it cannot be displaced. This allows the rotating rod 18 to drive the laminating roller (not shown in the figure) mounted on the rotating rod 18 to rotate. One side of the laminating roller releases unused film, while the other side recycles and wraps the used film. When the film is on both sides... When a connection is formed on the coating roller, the output end of the hydraulic cylinder 11 drives the coating plate 12 to rise and fall, and the coating plate 12 squeezes the film onto the back cover of the TV. When the coating plate 12 squeezes the back cover of the TV, the back cover of the TV is subjected to the squeezing force, which squeezes the placement plate 7 and squeezes the first strong spring 8 to shrink and deform. At the same time, the first strong spring 8 has a reaction force on the placement plate 7, thereby achieving a slow descent and preventing excessive squeezing force from damaging the back cover of the TV. When the coating plate 12 squeezes the film, it works with the base 1 to squeeze and cut the film coating area. This operation can be performed multiple times to achieve multiple coatings on the back cover of the TV. If it is necessary to disassemble the coating roller, the movable bracket 19 can be pulled and the slide rod 20 can be slid on the fixed bracket 21. At the same time, the slide rod 20 squeezes the second strong spring 22. At this time, the rotating rod 18 and the coating roller can be disassembled, and the spare roller 5 can be replaced at any time, reducing the time to take out a new coating roller.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
