Description

Technical Field

[0001] This invention relates to the field of film processing equipment technology, specifically to an apparatus for glossy surface treatment of PVC decorative film. Background Technology

[0002] PVC, short for Polyvinyl chloride, is mainly composed of polyvinyl chloride. Other components are added to enhance its heat resistance, toughness, and ductility. Essentially, PVC is a vacuum-formed film used for surface packaging of various panels. PVC decorative film is flexible, easy to shape, not brittle, non-toxic, non-polluting, and has a long shelf life. It has been increasingly accepted and recognized, and has great development and application value.

[0003] Existing PVC decorative films are made of multiple layers of PVC films with different properties. In order to achieve a smooth and glossy finish, a glossy film is usually laminated on the surface, and then high-temperature lamination and embossing are used to increase the gloss.

[0004] Existing processes have certain drawbacks. To achieve a smooth and glossy finish, a glossy coating is typically applied to the surface. However, current glossy surface treatment devices do not clean the film layer before the coating step, making the film layer and coating susceptible to foreign matter interference during coating. This results in small particle protrusions on the film surface, reducing the quality of the PVC decorative film lamination. Therefore, it is necessary to invent a glossy surface treatment device for PVC decorative films to solve the above problems. Summary of the Invention

Detailed Implementation

[0027] This invention provides an apparatus for glossy surface treatment of PVC decorative film, such as... Figure 1-7 As shown, the process of applying a glossy finish to the curved sheet material 2 includes a workbench 1 on which the curved sheet material 2 is placed. A slide bar 4 is positioned above the curved sheet material 2, and clamping strips 3 are symmetrically positioned on the front and back sides of the curved sheet material 2. The two clamping strips 3 are used to hold the curved sheet material 2. The workbench 1 has two through slots 12 located on the left and right sides of the curved sheet material 2, respectively. Support strips 5 are hinged within the through slots 12, and a decorative film is placed on the curved sheet material 2. The decorative film is pre-attached to the curved sheet material 2.

[0028] The top of the slide bar 4 is fixedly equipped with injection nozzle 1 41 and injection nozzle 2 42. The top of the workbench 1 is fixedly equipped with paint tank 8 and air pump 9. Paint tank 8 is connected to injection nozzle 1 41, and air pump 9 is connected to injection nozzle 2 42. A delivery pump is fixedly installed inside paint tank 8.

[0029] The bottom of the support strip 5 is equipped with a bending component, which is connected to the end of the slide bar 4. During operation, the curved plate 2 is fixed on the workbench 1, and the bending component is used to bend the slide bar 4 to fit the surface of the curved plate 2. Then, the bending component drives the slide bar 4 to move back and forth to clean the surface of the plate.

[0030] The bottom of the slide bar 4 has a paint hole 43, which is connected to the first injection nozzle 41. The front and rear sides of the slide bar 4 have air holes 44, which are inclined towards the curved plate 2 and are connected to the second injection nozzle 42. Air is supplied to the second injection nozzle 42 by the air pump 9, and the air is blown out from the air hole 44 to remove foreign objects from the surface of the curved plate 2.

[0031] The bottom of slider 4 has an arc-shaped curved surface that protrudes outwards.

[0032] The bending assembly consists of a motor 52 and a steel wire 53. A bottom groove 51 is formed along the length of the support bar 5. The motor 52 is slidably fitted within the bottom groove 51. The drive shaft of the motor 52 is welded to the steel wire 53. The end of the steel wire 53 away from the motor 52 is fixedly bound to the end of the slide bar 4. When the motor 52 winds the steel wire 53, both ends of the slide bar 4 sink, and the slide bar 4 bends to fit against the arc-shaped plate 2. A drive wheel is fixedly installed on the side of the motor 52, and the drive wheel is slidably fitted with the bottom groove 51.

[0033] The workbench 1 has a through groove 11, and the clamping bar 3 is located in the through groove 11. The upper end of the clamping bar 3 is welded with a protrusion 33, and the edge of the curved plate 2 rests on the protrusion 33. The curved plate 2 is clamped by the clamping bar 3 and the protrusion 33.

[0034] The clamping bar 3 has a vertical groove 31. A sliding plate 32 is fitted over the clamping bar 3, and the sliding plate 32 contacts the top of the worktable 1. A slider 321 is located within the groove 31, and the sliding plate 32 is connected to the slider 321. A spring 34 is welded between the lower ends of the two clamping bars 3. The spring 34 is in a stretched state, causing the two clamping bars 3 to move closer together, achieving a clamping effect.

[0035] The slide bar 4 has a second slide groove 45, which is located between the first injection nozzle 41 and the second injection nozzle 42. One end of the second slide groove 45 is connected to the first injection nozzle 41, and the other end of the second slide groove 45 is connected to the second injection nozzle 42. A blocking block 46 is slidably fitted inside the second slide groove 45. When the blocking block 46 moves toward the first injection nozzle 41, the first injection nozzle 41 is blocked. When the blocking block 46 moves toward the second injection nozzle 42, the second injection nozzle 42 is blocked.

[0036] The slider 4 and the blocking block 46 are made of soft rubber. The center of the second slide groove 45 is open and connected to the outside. The blocking block 46 is in the shape of an inverted T. The lateral end of the blocking block 46 slides in conjunction with the second slide groove 45. The longitudinal end of the blocking block 46 extends to the outside of the slider 4 through the opening.

[0037] During operation, first move the barrier block 46 towards injection nozzle 41 to block it. Start the air pump to clean the surface of the board, ensuring it is free of foreign objects. Then move the barrier block 46 towards injection nozzle 42 to block it. Next, the paint tank 8 begins operation, applying paint to the board.

[0038] A base 7 is provided below the workbench 1. A ball 71 is welded to the top of the base 7. Multiple support rods 14 are welded at equal angles to the bottom of the workbench 1. The lower ends of the multiple support rods 14 converge and are welded to a ball joint 13, which is hinged to the ball 71. Multiple large electric actuators 72 are fixedly installed on the top of the workbench 1. Each large electric actuator 72 corresponds to one of the support rods 14, and the upper end of the large electric actuator 72 contacts the support rod 14.

[0039] Multiple large electric actuators 72 extend and retract in a clockwise direction, causing the workbench 1 to oscillate clockwise, thereby accelerating the spread of the coating. The slider 4 moves back and forth, ensuring that the coating evenly covers the entire curved plate 2.

[0040] A support plate 15 is provided above the ball joint 13. The end of the support plate 15 is welded to the body of the support rod 14. Two small electric actuators 6 are fixedly installed on the top of the support plate 15, and the two small electric actuators 6 correspond one-to-one with the two support bars 5. The lower end of the small electric actuator 6 is welded to the support plate 15, and the upper end of the small electric actuator 6 contacts the bottom of the support bar 5.

[0041] During operation, the small electric actuator 6 extends, lifting the support strip 5, with the top of the support strip 5 contacting the edge of the curved plate 2. This provides support.

[0042] In summary, this device for glossy surface treatment of PVC decorative film uses clamping strips 3 and support strips 5 to fix the sheet material onto the workbench 1. Through the cooperation of a slide bar 4, injection nozzle 1 41, injection nozzle 2 42, paint tank 8, and air pump 9, the surface of the sheet material is first cleaned to remove foreign matter before spraying. This avoids the film layer and paint being easily affected by foreign matter during coating, which could lead to small particle protrusions on the film surface and reduce the quality of the PVC decorative film lamination.
