Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment equipment, in particular to a surface treatment equipment for a PVC decorative film. Background Art

[0002] PVC decorative film is a new type of decorative material made from high molecular polymers, various additives, calendering and compounding. It can be compounded with metals, wood, plastics and other materials, and is widely used in home appliances, interior decoration, billboards and other fields.

[0003] During the production process of PVC decorative film, a layer of liquid UV coating is sometimes sprayed on its surface. The UV coating is then irradiated with ultraviolet light to solidify it on the surface of the PVC decorative film. In this way, the UV coating is used to increase the hardness, wear resistance and other properties of the PVC decorative film, thereby comprehensively improving the performance of the PVC decorative film.

[0004] During the UV treatment of PVC decorative film, the UV coating first adheres to the surface of the PVC decorative film in the form of droplets. However, in the prior art, the PVC decorative film is generally in a state of continuous motion during the processing. At this time, the UV coating located at the edge of the PVC decorative film surface is very easy to slide off, resulting in poor UV coating coverage at the edge of the PVC decorative film. Utility Model Content

[0005] The purpose of the utility model is to provide a PVC decorative film surface treatment device, which blocks the middle part of the three front ultraviolet lamps through a shading component, so that the UV coating on the edges of both sides of the PVC decorative film is irradiated and cured first, thereby improving the coverage effect of the UV coating at the edge position.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a PVC decorative film surface treatment device, comprising two first racks and two second racks, the second racks being located behind the first rack, the PVC decorative film to be treated being located between the two first racks and between the two second racks, and the two second racks being directly provided with a plurality of ultraviolet lamps for curing UV coatings.

[0007] A cover plate is provided on the top of the ultraviolet lamp tube, and both ends of the cover plate are respectively connected to the two second frames. A shading assembly is provided on the cover plate, and the shading assembly includes two clamping rods located at the bottom of the cover plate. The rear ends of the clamping rods are rotatably connected to the cover plate. Three shading cloth covers are provided at the bottom of the cover plate, and the three shading cloth covers are respectively covered on the outer ends of the three ultraviolet lamp tubes located at the front, and end tubes are fixed at both ends of the shading cloth cover.

[0008] The top end of the end tube is rotatably connected to a first sliding sleeve, which is sleeved on the outer end of the clamping rod on the corresponding side. The two clamping rods can be rotated to open and close and control the distance between the two end tubes at both ends of the shading cloth cover.

[0009] Furthermore, a sliding groove is provided on the cover plate, an adjusting rod is provided on the top of the sliding groove, both ends of the adjusting rod are rotatably connected to end plates, the end plates are fixed on the top of the cover plate, and both ends of the adjusting rod pass through the two end plates and are fixed with knobs.

[0012] The unprocessed PVC decorative film is rolled up on the outer end of the fixed shaft. The damping bearing allows the PVC decorative film to be straightened due to the damping during the pulling process. The reason for setting up four fixed shafts at the same time is that when the PVC decorative film on one of the fixed shafts is pulled and processed, a new unprocessed PVC decorative film can be fixed on the outer end of the other fixed shafts. When the PVC decorative film on one of the fixed shafts is processed, the cross end plate is rotated to continue processing the PVC decorative film on the other fixed shafts. In this way, the PVC decorative film can be processed alternately, which is more efficient.

[0013] Furthermore, a dust removal assembly is provided between the second rack and the first rack, and the dust removal assembly includes an air duct, and both ends of the air duct are detachably connected to the rear sides of the two first racks.

[0014] A dust suction groove is provided at the bottom end of the air duct, and detachable fans are provided at both ends of the air duct. The dust suction groove faces the PVC decorative film at the bottom thereof, so as to absorb dust and impurities on the surface thereof.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] The utility model provides Figure 1-9 The PVC decorative film surface treatment equipment shown includes two first racks 1 and two second racks 5, wherein the second racks 5 are located at the rear side of the first rack 1, and the PVC decorative film to be treated is located between the two first racks 1 and between the two second racks 5. The two second racks 5 are directly provided with multiple ultraviolet lamps 12 for curing UV coatings.

[0036] A cover plate 6 is provided on the top of the ultraviolet lamp tube 12, and both ends of the cover plate 6 are respectively connected to the two second frames 5. A shading assembly 8 is provided on the cover plate 6, and the shading assembly 8 includes two clamping rods 805 located at the bottom of the cover plate 6. The rear ends of the clamping rods 805 are rotatably connected to the cover plate 6. Three shading cloth covers 808 are provided at the bottom of the cover plate 6. The three shading cloth covers 808 are respectively covered on the outer ends of the three ultraviolet lamp tubes 12 located at the front, and end tubes 809 are fixed at both ends of the shading cloth cover 808.

[0037] The top end of the end tube 809 is rotatably connected to a first sliding sleeve 804 , which is sleeved on the outer end of the clamping rod 805 on the corresponding side. The two clamping rods 805 can rotate open and close and control the distance between the two end tubes 809 at both ends of the shading cloth cover 808 .

[0038] The PVC decorative film that has been dusted and sprayed with UV paint moves between the two second racks 5. When it reaches the bottom of the ultraviolet lamp tube 12, the ultraviolet light emitted by the ultraviolet lamp tube 12 can cure the UV paint on the surface of the PVC decorative film and form a coating. However, the three ultraviolet lamp tubes 12 at the front are blocked by the shading cloth cover 808. The shading cloth cover 808 blocks the middle part of the ultraviolet lamp tube 12. Therefore, only the light at the edge positions on both sides of the blocked ultraviolet lamp tube 12 can irradiate the surface of the PVC decorative film, which makes the UV paint on the edges of both sides of the PVC decorative film be irradiated and cured first, and the UV paint in the middle position be irradiated and cured later. Among the three shading cloth covers 808, the closer the shading cloth cover 808 is, the more parts of the outer end of the ultraviolet lamp tube 12 it blocks. This makes the ultraviolet light gradually irradiate from the edge positions on both sides of the PVC decorative film to the center position. In this way, the edges on both sides of the PVC decorative film will be cured first, thereby reducing the risk of UV paint at the edge positions dripping during movement.

[0039] In order to adjust the distance between the end tubes 809 at both ends of the shade cloth cover 808, as shown in FIG. Figure 3 、 5As shown, a sliding groove is provided on the cover 6, and an adjusting rod 802 is provided on the top of the sliding groove. Both ends of the adjusting rod 802 are rotatably connected to end plates 807, and the end plates 807 are fixed on the top of the cover 6. Both ends of the adjusting rod 802 pass through the two end plates 807 and are fixed with knobs.

[0040] The outer end of the adjusting rod 802 is sleeved with two adjusting seats 801 and is movably connected to the adjusting seat 801 through a thread. The bottom end of the adjusting seat 801 is rotatably connected to a connecting shaft 803. The bottom end of the connecting shaft 803 extends to the bottom of the cover plate 6 through a sliding groove and is fixed with a second sliding sleeve 806. The two second sliding sleeves 806 are respectively sleeved on the outer ends of the two clamping rods 805.

[0041] The adjusting rod 802 is driven to rotate by the knob, and under the action of the thread, the adjusting seat 801 will slide on the outer end of the adjusting rod 802. The two adjusting seats 801 move in opposite directions at the outer end of the adjusting rod 802. Therefore, the rotation of the adjusting rod 802 will make the two adjusting seats 801 approach each other or move away from each other, and the movement of the adjusting seat 801 will make the connecting shaft 803 move inside the sliding groove, thereby driving the second sliding sleeve 806 and the corresponding adjusting seat 801 to move synchronously. The two second sliding sleeves 806 approach each other, and the angle between the two clamping rods 805 will decrease. Conversely, the angle between the two clamping rods 805 will increase. The two end tubes 809 at both ends of the same blackout cloth cover 808 are respectively connected to the two clamping rods 805. The opening and closing of the angle of the clamping rod 805 will drive the end tube 809, thereby adjusting the distance between the two end tubes 809.

[0042] The change in the spacing between the end tubes 809 will control the stretching or contraction of the shading cloth cover 808. When the shading cloth cover 808 stretches, the ultraviolet lamp tube 12 will be blocked more. When the shading cloth cover 808 contracts, the ultraviolet lamp tube 12 will be blocked less. By adjusting the spacing between the two end tubes 809, the width of the ultraviolet lamp tube 12 blocked can be adjusted to adapt to PVC decorative films of different widths.

[0043] The untreated PVC decorative film is fixed between the two first racks 1, as shown in FIG. Figure 1 、 2 As shown in 8, the two first frames 1 are rotatably connected with a cross end plate 2, the two cross end plates 2 are located between the two first frames 1, and four fixed shafts 3 are provided between the two cross end plates 2. The cross end plate 2 has four branches, and each fixed shaft 3 corresponds to a branch of the cross end plate 2. Both ends of the fixed shaft 3 are movably connected to the two cross end plates 2 through damping bearings.

[0044] The unprocessed PVC decorative film is rolled up on the outer end of the fixed shaft 3, and the damping bearing allows the PVC decorative film to be stretched straight due to the damping during the pulling process. The reason for setting four fixed shafts 3 at the same time is that when the PVC decorative film on one of the fixed shafts 3 is pulled for processing, a new unprocessed PVC decorative film can be fixed on the outer end of the other fixed shafts 3. When the PVC decorative film on one of the fixed shafts 3 is processed, the cross end plate 2 is rotated to continue processing the PVC decorative film on the other fixed shafts 3, so that the PVC decorative film can be processed alternately, and the processing efficiency is higher.

[0045] Before spraying UV coating, it is also necessary to deal with the dust on the surface of the PVC decorative film, such as Figure 1 、 9 As shown, a dust removal assembly 4 is provided between the second rack 5 and the first rack 1 . The dust removal assembly 4 includes an air duct 401 . Both ends of the air duct 401 are detachably connected to the rear sides of the two first racks 1 .

[0046] A dust suction groove 403 is provided at the bottom of the air duct 401 , and detachable fans 402 are provided at both ends of the air duct 401 . The dust suction groove 403 faces the PVC decorative film at the bottom thereof to absorb dust and impurities on the surface thereof.

[0047] After the PVC decorative film is pulled out from the outer end of the fixed shaft 3, it first passes through the bottom of the dust removal component 4. At this time, the fan 402 is turned on to drive the air flow and discharge the air inside the air duct 401. This will create suction at the dust suction groove 403. Under the action of the suction force, the dust on the surface of the PVC decorative film is sucked into the inside of the air duct 401 through the dust suction groove 403 and is finally discharged to the outside by the fan 402.

[0048] UV coating is first sprayed on the surface of PVC decorative film in liquid form. Figure 2 、 4 As shown in FIG. 7 , a protective cover 10 and a collecting pool 11 are provided between the two second racks 5 . The collecting pool 11 is located at the bottom of the protective cover 10 . Both the protective cover 10 and the collecting pool 11 are located in front of the ultraviolet lamp 12 .

[0049] A delivery pipe 13 is provided inside the protective cover 10, and a plurality of atomizing nozzles 14 are fixedly provided at the bottom end of the delivery pipe 13. One end of the delivery pipe 13 passes through the second frame 5 on the corresponding side. The second frame 5 is also provided with a recovery pipe passing through the second frame 5, and the recovery pipe is communicated with the inside of the collection tank 11.

[0050] After the dust removal treatment, the PVC decorative film moves and passes through the position between the protective cover 10 and the collection tank 11. At this time, the liquid UV paint flows into the delivery pipe 13, and is atomized by the atomizing nozzle 14 and then sprayed downward onto the surface of the PVC decorative film. The UV paint adheres to the surface of the PVC decorative film in the form of small droplets, and the droplets that do not fall on the surface of the PVC decorative film fall into the collection tank 11 and are collected, and can eventually be recycled through the recovery pipe.

[0051] In order to prevent UV coating from dripping from the edge of PVC decorative film, Figure 4 、 6 As shown, two side support assemblies 9 are provided between the ultraviolet lamp tube 12 and the protective cover 10, and the side support assembly 9 includes a boss 901. The two bosses 901 are respectively fixed on the two second frames 5. Fixed rods 902 are fixed on both sides of the boss 901. The outer ends of the fixed rods 902 are sleeved with fixed nuts 903 and mounting plates 904. The fixed nuts 903 are movably connected to the fixed rods 902 through threads, and the mounting plates 904 are clamped between the fixed nuts 903 and the bosses 901.

[0052] An isolation piece 905 is fixedly provided at one end of the mounting piece 904, and a roller shaft 906 is rotatably connected to the isolation piece 905. A supporting roller 907 is fixedly provided at the outer end of the roller shaft 906. The supporting roller 907 is in an inclined state. The supporting rollers 907 of the two side support assemblies 9 lift the PVC decorative film upward from both sides, so that the edges on both sides of the PVC decorative film are slightly bent upward.

[0053] The PVC decorative film after spraying continues to move and passes through the side support assembly 9. The two side support assemblies 9 are respectively located on both sides of the PVC decorative film. The inclined support roller 907 on the side support assembly 9 contacts the edge position of the PVC decorative film on the corresponding side and lifts the edge position of the PVC decorative film upward, so that its two side edges bend upward, resulting in the UV paint at the edge position unable to flow further toward the edge direction, thereby avoiding the dripping of paint at the edge position, and the mounting piece 904 is clamped and fixed on the outer end of the fixing rod 902. The angle of the mounting piece 904 at the outer end of the fixing rod 902 can be adjusted when fixed, thereby adjusting the inclination angle of the support roller 907, thereby adjusting the degree of upward bending of the edge position of the PVC decorative film.

[0054] The treated PVC decorative film needs to be rolled up. Figure 1 、 3 As shown, a driving assembly 7 is provided at the rear side of the ultraviolet lamp 12 . The driving assembly 7 includes two central shafts 701 distributed up and down. An elastic roller 702 is fixed to the outer end of the central shaft 701 , and the PVC decorative film is sandwiched between the two elastic rollers 702 .

[0055] Gears 703 are fixed to the outer ends of the two central shafts 701, and the two gears 703 are meshed with each other. Mounting plates are fixed to the rear sides of the two second frames 5. The two ends of the central shaft 701 are respectively rotatably connected to the two mounting plates. One of the gears 703 is provided with a motor 704 for driving the central shaft 701 to rotate.

[0056] A winding shaft is provided on the rear side of the driving component 7, and the processed PVC decorative film is rolled up and fixed on the outer end of the winding shaft. Both ends of the winding shaft are rotatably connected to vertical plates, and a handwheel for driving the winding shaft to rotate is provided on one side of one vertical plate. One end of the winding shaft passes through the vertical plate and is fixedly connected to the handwheel. The device also has a base, and the first frame 1 and the second frame 5 are both fixed on the base, and the bottom end of the vertical plate is also connected to the base.

[0057] One of the central shafts 701 is driven to rotate by the motor 704. Since the gears 703 at the outer ends of the two central shafts 701 are engaged with each other, after one of the central shafts 701 rotates, the two central shafts 701 can rotate synchronously, thereby driving the two elastic rollers 702 to rotate synchronously. The PVC decorative film is clamped between the two elastic rollers 702. After the two rotate, the PVC decorative film is pulled, so that the PVC decorative film moves continuously and is surface-treated during the movement. The treated PVC decorative film is pulled backward from between the two second frames 5. While the driving component 7 pulls out the PVC decorative film, the hand wheel is used to drive the winding shaft to rotate, and the pulled PVC decorative film is wound and rolled up on the outer end of the winding shaft.

[0058] The reason for adopting the above-mentioned method for winding instead of directly using electricity to drive the winding shaft to rotate for winding is that if the winding shaft is directly driven by electricity to rotate, under the premise of constant angular velocity, the linear speed when pulling the PVC decorative film will continue to increase due to the gradual thickening of the wound PVC decorative film, which will cause the moving speed of the PVC decorative film to gradually increase during the processing process, which may cause the UV coating on its surface to be insufficiently exposed for time and unable to fully solidify. However, using the drive component 7 to drive and then manually winding can ensure that the PVC decorative film always moves at a uniform speed.

[0059] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
