Description

Technical Field

[0001] This application relates to the technical field of surface pretreatment of decorative strip profiles, and more particularly to a pretreatment device for surface texture processing of decorative strip profiles. Background Technology

[0002] In the fields of architectural decoration, furniture manufacturing, and industrial profiles, surface decoration technology for strip profiles (such as aluminum alloy profiles and PVC profiles) is receiving increasing attention. Among them, pattern transfer printing has become one of the mainstream surface treatment methods because it can give profiles realistic wood grain, stone grain, or other textured patterns, and also has excellent properties such as wear resistance and weather resistance. Its basic principle is as follows: transfer paper with a preset pattern is tightly wrapped around the surface of the strip profile, and then a plastic bag is placed on the outside. Vacuum treatment is used to make the transfer paper adhere tightly to the surface of the profile, and then the whole thing is placed in an oven for high-temperature baking. Under the combined action of heat and negative pressure, the ink pattern on the transfer paper sublimates and penetrates into the coating or substrate on the surface of the profile, thereby forming a permanent decorative layer.

[0003] Currently, in the pre-processing steps of the aforementioned pattern transfer printing process, after the strip profile is covered with transfer paper, it needs to be sealed with a plastic bag to achieve vacuum sealing. This bagging operation is mostly done manually. However, the strip profiles are usually quite long (common specifications range from several meters to six meters), and operators must hold the plastic bag and gradually cover it from one end of the profile to the other, ensuring that the bag remains flat and undamaged while preventing the already covered transfer paper from shifting or wrinkling. Due to the length and weight of the profiles, single-person operation is extremely inconvenient, often requiring multiple people to work together, resulting in high labor intensity, low bagging efficiency, and difficulty in meeting the needs of mass production. Summary of the Invention

[0005] Therefore, one objective of this application is to provide a pre-treatment device for surface texture processing of decorative strip profiles. The bagging mechanism can cover the outside of the strip profile with a plastic bag, which effectively avoids problems such as wrinkles and damage to the plastic bag caused by differences in technique or excessive length of the profile when bagging manually, thereby improving the efficiency of pre-treatment.

[0006] To achieve the above objectives, a first aspect of this application provides a pre-processing device for surface texture processing of decorative strip profiles, comprising a base plate, a feeding assembly, and a bagging mechanism. The base plate has a support box on one side, and multiple guide plates at the bottom of the support box. The feeding assembly is disposed inside the support box.

[0017] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0018] The following description, in conjunction with the accompanying drawings, describes a pre-processing apparatus for surface texture processing of decorative strip profiles according to an embodiment of this application.

[0019] like Figures 1 to 7 As shown in the figure, a pre-processing device for surface texture processing of decorative strip profiles according to an embodiment of this application may include a base plate 1, a feeding assembly 2, and a bagging mechanism 3.

[0020] Among them, a support box 9 is provided on one side of the base plate 1, and multiple guide plates 8 are provided at the bottom of the support box 9. The feeding component 2 is set inside the support box 9, and multiple support components 4 are provided in pairs on the base plate 1. The support components 4 are used to support the strip profile.

[0021] In the embodiments of this application, multiple strip profiles are stacked inside the support box 9. The guide plate 8 includes a horizontal part and an inclined part. The horizontal part is used to support the strip profiles, and the inclined part is used to guide the feeding of the strip profiles. The support surface of the support component 4 is lower than the height of the guide plate 8. The feeding component 2 can push out the bottommost strip profile and slide it down the inclined part onto the support component 4.

[0022] Furthermore, each pair of support components 4 forms a group, and the two support components 4 are symmetrically arranged. Multiple support components 4 support the strip profile simultaneously, forming multiple support points. When one group of support components 4 rotates to separate from the strip profile (no longer supporting the strip profile), the remaining support components 4 can still stably support the strip profile.

[0023] The bagging mechanism 3 includes a linear movement mechanism 31, a support frame 32, multiple bag-supporting components 33, and a connecting component 34. The linear movement mechanism 31 is disposed on the upper surface of the base plate 1, and a first mounting plate is provided on its slide. The support frame 32 is connected to the first mounting plate. Multiple bag-supporting components 33 are disposed on the side wall of the support frame 32. The bag-supporting components 33 can expand the plastic bag. The side wall of the support frame 32 is provided with a first groove 321. The connecting component 34 is disposed in the first groove 321, and the multiple bag-supporting components 33 are connected to each other through the connecting component 34.

[0024] In the embodiments of this application, the linear movement mechanism 31 may be a linear guide or a lead screw pair structure, used to drive the support frame 32 to move linearly along the length direction of the base plate 1. The support frame 32 is a rectangular frame structure, which supports the bag support assembly 33 and the connecting assembly.

[0025] Furthermore, the bag-supporting assembly 33 can expand the flat plastic bag so that it can be fitted over the outside of the strip profile.

[0026] Understandably, since the plastic bags are initially rolled up, they are difficult to unfold due to static electricity. To address this, multiple air-blowing pipes 12 can be installed on the inner wall of the support frame 32. These pipes 12 are connected to a main pipe inside the support frame 32, which is externally connected to an air pump 16. When the air pump is activated, air is introduced through the main pipe and ejected from each air-blowing pipe 12, further assisting in unfolding the plastic bags with the help of airflow.

[0027] To facilitate cutting plastic bags, a cutting assembly is provided on the base plate 1. The cutting assembly includes two hydraulic cylinders 13. The output end of the hydraulic cylinder 13 is provided with a lifting plate 14. The lower surface of the lifting plate 14 is provided with a cutting blade 15. The upper surface of the base plate 1 is provided with a base. The base is provided with a blade groove corresponding to the cutting blade 15. When the hydraulic cylinder 13 is started, it drives the lifting plate 14 and the cutting blade 15 to move down to cut the plastic bag.

[0028] The slide table is provided with avoidance components 5 on both sides. When the support frame 32 moves with the slide table, the avoidance components 5 are used to drive the corresponding support components 4 to rotate 90 degrees so as to automatically avoid the support frame 32.

[0029] In the embodiments of this application, when the support frame 32 moves to the vicinity of the support component 4, the avoidance component 5 first drives the corresponding support component 4 to rotate 90 degrees, thereby separating the support component 4 from the strip profile, avoiding interference with the movement of the support frame 32, and realizing automatic avoidance.

[0030] Further, see Figure 7 In order to facilitate the wrapping of the strip profile with transfer paper, a transfer paper rewinding shaft is provided on one side of the base plate 1 so that the transfer paper can be laid flat on the support component 4.

[0031] In one embodiment of this application, such as Figure 5 As shown, the bag support assembly 33 includes a slide rail 331, a slide plate 333, an opening column 334, a first toothed plate 335, and a first gear 336. The slide rail 331 is fixedly mounted on the side wall of the support frame 32, and a first slider 332 is slidably connected to the slide rail 331. The slide plate 333 is mounted on the first slider 332. The opening column 334 is vertically mounted on the slide plate 333. The first toothed plate 335 is mounted on the side wall of the slide plate 333. A first support shaft 337 is rotatably connected to the support frame 32. The first gear 336 is mounted on the first support shaft 337 and meshes with the first toothed plate 335.

[0032] In the embodiments of this application, there are four bag support components 33, which are respectively arranged at the four right angles of the support frame 32. The slide rail 331 guides the movement of the slide plate 333. The opening of the plastic bag is respectively fitted onto the four expansion columns 334. When the four expansion columns 334 expand outward at the same time, the bag opening can be opened, and the maximum opening of the bag opening is greater than the cross-section of the strip profile, so as to facilitate the plastic bag to be fitted onto the outside of the strip profile.

[0033] Furthermore, such as Figure 4As shown, the connecting assembly 34 includes multiple pairs of pulleys 341 and belts 342. The slide plate 333 is symmetrically provided with a first support shaft 337 and a second support shaft 343 on both sides. Each pair of pulleys 341 forms a group and is respectively set on the first support shaft 337 and the second support shaft 343. The multiple pulleys 341 are connected by belts 342.

[0034] It should be noted that one of the first support shafts 337 is connected to an external motor (not shown in the figure), which can drive it to rotate. Then, through the cooperation between the pulley 341 and the belt 342, the other first support shafts 337 and the second support shaft 343 are driven to rotate synchronously.

[0035] When the first support shaft 337 rotates, it can drive the corresponding first gear 336 to rotate. With the cooperation of the first toothed plate 335, the slide plate 333 moves accordingly, thereby driving the spreading column 334 to move outward or inward.

[0036] During the process of opening the plastic bag, to prevent the plastic bag from slipping off the opening post 334, such as... Figure 5 As shown, a second mounting plate 6 is provided on the slide plate 333, and a first spring 7 is provided on the second mounting plate 6. A limiting block 10 is provided at the end of the first spring 7. Electromagnetic blocks are embedded in the opposite surfaces of the limiting block 10 and the supporting column 334. When the electromagnetic blocks are energized, they generate magnetic attraction and attract each other, which can clamp the plastic bag between the limiting block 10 and the supporting column 334, effectively preventing the plastic bag from falling off.

[0037] Furthermore, the side of the limiting block 10 adjacent to the supporting column 334 is curved, which provides a better fixing effect for the plastic bag.

[0038] In one embodiment of this application, such as Figure 1 As shown, the support assembly 4 includes a rotating shaft 41, a support plate 42, a second gear 43, a second toothed plate 44, and a second spring 45. The base plate 1 has two symmetrically arranged second grooves 11. The bottom of the rotating shaft 41 is rotatably disposed in the second groove 11. The support plate 42 and the second gear 43 are both fixedly disposed on the rotating shaft 41, and the support plate 42 is located at the top of the rotating shaft 41. The second toothed plate 44 is slidably disposed in the second groove 11 and meshes with the second gear 43. A fixing plate is provided in the second groove 11. The two ends of the second spring 45 are respectively connected to the fixing plate and the second toothed plate 44.

[0039] In the embodiments of this application, the support plate 42 can rotate with the rotating shaft 41. When the support plate 42 rotates to be parallel to the long side of the strip profile, the support plate 42 no longer contacts the strip profile, making it easier for the support frame 32 to pass through.

[0040] Furthermore, when the support frame 32 moves towards the strip profile, the third toothed plate 52 on the slide first engages with the second gear 43. During this process, the second gear 43 rotates, and with the cooperation of the second toothed plate 44, the second spring 45 is stretched. At the same time, the support plate 42 rotates 90 degrees, separating from the strip profile. The strip profile at this position is in a suspended state, facilitating the passage of the support frame 32. When the third toothed plate 52 moves to the point of separating from the second gear 43, under the elastic action of the second spring 45, the second toothed plate 44 drives the second gear 43 to rotate in the opposite direction, the support plate 42 resets, and continues to support the strip profile.

[0041] In one embodiment of this application, such as Figure 2 As shown, the avoidance component 5 includes a connecting plate 51 connected to the side wall of the slide and a third toothed plate 52 connected to the connecting plate 51. The third toothed plate 52 is slidably disposed inside the second groove 11 and has a meshing relationship with the second gear 43.

[0042] In the embodiments of this application, the inner wall of the second groove 11 is provided with a sliding groove, the third toothed plate 52 is slidably connected to the sliding groove, the connecting plate 51 is an L-shaped plate, the third toothed plate 52 is connected to the slide table, and the third toothed plate 52 is moved by the movement of the slide table.

[0043] In one embodiment of this application, such as Figure 4 As shown, the feeding assembly 2 includes a drive component 21 and a push plate 22. The drive component 21 is installed on the outer wall of the support box 9, and its telescopic end passes through the support box 9 and is connected to the push plate 22. One side wall of the support box 9 is provided with an opening, and the push plate 22 corresponds to the opening.

[0044] It should be noted that the driving component 21 described in this embodiment can be an electric push rod. The position of the push plate 22 can be easily adjusted by the electric push rod. The push plate 22 can push out the bottommost strip profile. The pushed-out strip profile will slide down along the guide plate 8 onto the support plate 42.

[0045] Specifically, the relevant personnel first lay the transfer paper on the support plate 42, then activate the drive unit 21 to push out the bottom strip, allowing it to slide down the inclined guide plate 8 onto the transfer paper. After that, the relevant personnel wrap the transfer paper around the outside of the strip and seal both ends.

[0046] Next, the opening of the plastic bag is placed on the expansion column 334, and the electromagnetic block is energized to generate a magnetic attraction force, which attracts the limiting block 10 to stick tightly to the expansion column 334. The plastic bag is clamped between the limiting block 10 and the expansion column 334, and at this time the first spring 7 is stretched.

[0047] Subsequently, personnel activate the linear movement mechanism 31, which moves the support frame 32, dragging the plastic bag forward. During this process, the air blowing pipe 12 continuously blows air into the plastic bag, forcing it to unfold. As the slide moves, the connecting plate 51 and the third toothed plate 52 move synchronously. When the third toothed plate 52 engages with the second gear 43, the second gear 43 rotates. With the cooperation of the second toothed plate 44, the second spring 45 is stretched, driving the support plate 42 to rotate 90 degrees. The support plate 42 separates from the strip profile, leaving the strip profile suspended, allowing the support frame 32 to pass through smoothly. When the third toothed plate 52 separates from the second gear 43, under the elastic action of the second spring 45, the second toothed plate 44 drives the second gear 43 to rotate in the opposite direction, and the support plate 42 resets, continuing to support the strip profile. In this way, the strip profile can be continuously bagged, which is more convenient and efficient than manual bagging.

[0048] After the plastic bag is completely wrapped around the profile strip, the hydraulic cylinder 13 is activated to cut it using the cutting blade 15. Then, a vacuum is applied to the plastic bag to ensure the transfer paper adheres tightly to the profile surface. Finally, the entire profile is placed in an oven or transfer furnace for heating. After baking, the profile strip is removed and allowed to cool. Then, the outer plastic bag is removed, and the transfer paper is peeled off or removed. The surface of the transferred profile is then cleaned.

[0049] In summary, the pre-processing device for surface texture processing of decorative strip profiles according to the embodiments of this application has a bagging mechanism that can cover the outside of the strip profile with a plastic bag, effectively avoiding problems such as bag wrinkles and damage caused by differences in technique or excessive length of the profile when bagging manually, thus improving the efficiency of pre-processing.
