A stainless steel random pattern PVC film laminating device

Abstract

This utility model discloses a stainless steel random-pattern PVC film laminating device, specifically relating to the field of stainless steel processing technology. It includes a frame base, a driving component slidably mounted horizontally on the frame base, a scraping component mounted on the driving component, and an atomizing spray component at the front of the scraping component. This stainless steel random-pattern PVC film laminating device pre-washes the stainless steel sheet placed on the support platform with the atomizing spray component, effectively cleaning dust and other impurities from the stainless steel sheet. This prevents air bubbles from forming at the interface during lamination or reducing the bonding strength between the PVC film and the sheet due to residual impurities, thus improving the durability and reliability of the lamination layer. After the PVC film is laminated onto the stainless steel sheet, the driving component drives the scraping component to scrape away the cleaning liquid between the lamination interfaces, effectively preventing residual cleaning liquid from forming a water film at the lamination interface and causing air bubbles.

Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, and in particular to a stainless steel random pattern PVC film lamination device. Background Technology

[0002] In modern industrial production, stainless steel random-patterned PVC film, with its unique textured appearance, good wear resistance and corrosion resistance, is widely used for surface decoration and protection of products such as building decoration, home appliance shells, and kitchen and bathroom equipment. As the market continues to improve the requirements for product appearance quality and functionality, the bonding process of stainless steel random-patterned PVC film with various substrates has become particularly critical.

[0003] In the bonding process of stainless steel random pattern PVC film and substrate, the problem of air bubbles at the bonding interface has always been a key factor restricting the improvement of product quality. With the increasingly stringent requirements for product surface quality in industries such as building decoration and home appliance manufacturing, air bubbles at the bonding interface not only destroy the integrity and aesthetics of the unique texture of stainless steel random pattern PVC film, but also significantly reduce the durability and reliability of the bonding layer due to stress concentration caused by air bubbles, thus shortening the product's service life. Utility Model Content

[0004] The main objective of this invention is to provide a stainless steel random-pattern PVC film laminating device, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stainless steel random pattern PVC film laminating device includes a frame base, four support legs symmetrically fixed at the four corners of the bottom end of the frame base, a drive assembly slidably mounted on the frame base in the horizontal direction, a support platform fixedly connected to the middle of the inner cavity of the frame base, and multiple liquid lowering grooves symmetrically and equidistantly opened on both sides of the top of the support platform away from the middle, a scraping assembly mounted on the drive assembly, and an atomizing spraying assembly provided in front of the scraping assembly.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-5 As shown, a stainless steel random pattern PVC film bonding device includes a frame base 1, four support legs 2 are symmetrically fixed at the four corners of the bottom end of the frame base 1, a drive assembly 3 is slidably arranged in the horizontal direction on the frame base 1, a support platform 4 is fixedly connected to the middle of the inner cavity of the frame base 1, and multiple liquid grooves 41 are symmetrically opened at equal intervals on both sides of the top of the support platform 4 away from the middle, a scraping assembly 5 is installed on the drive assembly 3, and an atomizing spraying assembly 6 is arranged in front of the scraping assembly 5.

[0024] In actual use, the stainless steel plate placed on the support platform 4 is pre-sprayed and rinsed by the atomizing spray component 6, which can effectively clean the dust and other impurities on the stainless steel plate and avoid the formation of bubbles at the interface or the reduction of the bonding strength between the PVC film and the plate due to the residue of impurities.

[0025] After the PVC film is applied to the stainless steel sheet, the scraping component 5 is driven by the driving component 3 to scrape off the cleaning liquid between the bonding interfaces, effectively preventing residual cleaning liquid from forming a water film at the bonding interface and causing bubbles.

[0026] Specifically, the atomizing spraying assembly 6 includes a liquid storage box 61, which is fixedly installed at the front end of the fixed frame 51. Multiple atomizing nozzles 63 are equidistantly installed on the inclined surface at the front end of the liquid storage box 61. An upper liquid pipe 62 is installed through the middle of the top of the liquid storage box 61. The upper liquid pipe 62 protrudes from the outer surface of the inner cavity of the liquid storage box 61 and is fixedly connected to the external liquid supply pipe 64 by a clamp.

[0027] The water pump injects cleaning fluid into the storage box 61 through the external liquid supply pipe 64. As the amount of cleaning fluid in the storage box 61 increases, the internal pressure increases. The high-pressure cleaning fluid is atomized and sprayed onto the stainless steel plate placed on the support platform 4 through the atomizing nozzle 63. The drive component 3 drives the storage box 61 to move back and forth to repeatedly flush the stainless steel plate.

[0028] Furthermore, the drive assembly 3 includes a servo motor 31, a slide block 34 and two connecting blocks 32. The servo motor 31 is fixedly installed on the front side of the middle of the bottom end of the inner cavity of the frame 1. The two connecting blocks 32 are symmetrically installed on the front and rear sides of the middle of the inner cavity of the frame 1. The slide block 34 is slidably connected to the lower side of the bottom end of the frame 1.

[0029] A lead screw 33 is rotatably connected between the opposing surfaces of the two connecting blocks 32. The output shaft of the servo motor 31 is fixedly connected to the lead screw 33 via a coupling. A lead screw nut 35 is threaded on the outer surface of the lead screw 33. The bottom end of the lead screw nut 35 is fixedly connected to the middle of the inner cavity of the slide block 34.

[0030] When the servo motor 31 is started, the output shaft of the servo motor 31 drives the lead screw 33 to rotate forward through the coupling, causing the threaded nut 35 on the outer surface of the lead screw 33 to drive the slide 34 and the scraping assembly 5 and atomizing spray assembly 6 on the upper part of the slide 34 to slide forward. Conversely, when the output shaft of the servo motor 31 drives the lead screw 33 to rotate backward through the coupling, the scraping assembly 5 and atomizing spray assembly 6 on the upper part of the slide 34 will slide backward.

[0031] Specifically, the scraping component 5 includes a first fixing frame 51, which is fixedly installed on the top of the slide block 34. A guide hole 52 is provided through the middle of the top of the first fixing frame 51. A guide rod 53 is slidably installed on the inner surface of the guide hole 52. A second fixing frame 54 is fixedly connected to the bottom of the guide rod 53. A spring 531 is sleeved on the outer surface of the guide rod 53. The two ends of the spring 531 are respectively held between the top of the inner cavity of the first fixing frame 51 and the second fixing frame 54.

[0032] A connecting rod 55 is fixedly connected between the two ends of the fixed frame 54 in the height direction, and multiple positioning pressure rollers 56 are equidistantly rotatably connected to the outer surface of the connecting rod 55;

[0033] Two upper rods 57 are symmetrically installed on the top of the fixed frame 54 away from the middle. Two L-shaped slide rods 58 are slidably connected to the outer surfaces of the two upper rods 57 respectively. A rubber scraper 59 is fixedly connected to the bottom of the two L-shaped slide rods 58.

[0034] The tension of spring 531 pushes guide rod 53 closer to support platform 4, thereby causing positioning pressure roller 56 rotatably connected to connecting rod 55 to come into contact with stainless steel plate placed on support platform 4. As drive assembly 3 is driven, multiple positioning pressure rollers 56 roll and press the front part of PVC film on stainless steel plate. Subsequently, rubber scrapers 59 on the rear side of multiple positioning pressure rollers 56 press against PVC film on stainless steel plate due to their own weight. As driven by multiple drive assemblies 3, rubber scrapers 59 push and extrude cleaning liquid between the interface of stainless steel plate and PVC film through their own weight.

[0035] It should be noted that the specific installation method, circuit connection method and control method of the servo motor 31 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
