Description

Technical Field

[0001] This invention relates to the field of spraying technology, and in particular to a spraying method and system for T-shaped profile side panels. Background Technology

[0002] Currently, in the metal product processing process, anti-corrosion coatings are usually sprayed onto the metal surface to protect the metal products. The anti-corrosion coating can form a protective film, effectively isolating the metal surface from contact with the external environment, preventing metal corrosion, and extending the service life of the metal. Spraying is a coating method that uses a spray gun or butterfly atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object to be coated. Spraying operations have high production efficiency, are suitable for manual operations and industrial automated production, and have a wide range of applications, mainly in hardware, plastics, furniture, military, shipbuilding and other fields. It is the most widely used coating method today.

[0003] Patent document CN205791308U discloses a splicing T-shaped cable tray, including a T-shaped arrangement of horizontal and vertical openings, and a T-shaped base plate. An outer horizontal side plate is fixed to the outer side of the horizontal opening of the T-shaped base plate, and an inner horizontal left side plate is fixed to the left end of the inner side of the horizontal opening, while an inner horizontal right side plate is fixed to the right end. A left and right longitudinal side plate are fixed to both sides of the longitudinal opening of the T-shaped base plate. The inner horizontal left side plate is connected to the left longitudinal side plate, and the inner horizontal right side plate is connected to the right longitudinal side plate. The inner horizontal left side plate, inner horizontal right side plate, and outer horizontal side plate are riveted to the horizontal edge of the T-shaped base plate along the horizontal opening. The left and right longitudinal side plates are riveted to the vertical edge of the T-shaped base plate along the longitudinal opening. This utility model has a simple and environmentally friendly structure, is easy to assemble and disassemble, and is highly practical.

[0004] However, in the actual production and spraying process of T-profile side panels, the inventors found the following problems with the existing spraying process: the existing support structure is not effective in supporting irregularly shaped materials like T-profile side panels, requiring manual loading, and it cannot cover the non-sprayed surfaces while providing support, resulting in poor spraying results; before spraying, the non-sprayed surfaces are mainly covered manually, which requires a lot of manpower, has a low degree of automation, and low production efficiency. In addition, the complex shape of the non-sprayed surfaces of the T-profile side panels causes the masking material to not adhere tightly to the substrate, resulting in paint penetration and material waste. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. By using a support mechanism in the support process where the support rod and sealing block precisely shield the longitudinal and transverse openings while supporting the side plate, high support stability and excellent support effect are achieved. Furthermore, in the spraying process, the first and second conveying components of the conveying mechanism work in conjunction with the support mechanism to automatically switch support points for two-stage spraying. The side plate, suspended by connecting ropes, avoids contact and prevents missed areas or uneven coating during secondary spraying, while ensuring uniform heat curing of the coating during the drying process. Additionally, in the recycling process, the support mechanism automatically returns to the first conveying component via a recycling component, forming a seamless automated production line. This solves the problems of poor support effect, poor shielding effect, and low automation in existing spraying processes.

[0006] To address the above technical problems, the following technical solution is adopted: A method for spraying T-profile side panels, comprising the following steps:

[0007] Step 1: Support process. After the longitudinal opening of the side plate is supported by the support rod of the support mechanism, the two sealing blocks on the support rod move to both ends of the transverse opening of the side plate, thereby shielding the longitudinal opening and the transverse opening.

[0008] Step 2: Spraying process. First, the support rod is connected to the first conveying component of the conveying mechanism to support and convey the side plate for surface spraying. Then, the two sealing blocks are connected to the second conveying component of the conveying mechanism to support and convey the side plate whose surface is blocked by the first conveying component for secondary spraying.

[0009] Preferably, the T-profile side panel spraying method further includes the following steps:

[0010] Step 3: Drying process. The second conveying component connects the two sealing blocks with a connecting rope to facilitate the lifting of the side plate for drying and to prevent the side plate from being blocked during drying.

[0011] Step 4: Recycling process. After the support mechanism on the second conveying component is separated from the dried side plate by the recycling component on the conveying mechanism, the recycling component will recycle the separated support mechanism back onto the first conveying component and output the processed side plate.

[0012] This application also provides a side panel spraying system, based on the above-described T-profile side panel spraying method, comprising:

[0013] The system includes a conveying mechanism, multiple support mechanisms that are detachably mounted on the conveying mechanism and used to support the side plates, a spraying mechanism and a drying mechanism arranged sequentially along the conveying direction of the conveying mechanism;

[0014] The support mechanism includes a support rod detachably mounted on the conveying mechanism for supporting the longitudinal opening, two sealing blocks movably mounted on both sides of the support rod for blocking the two ends of the transverse opening, and a drive assembly mounted on the support rod for driving the sealing blocks to move. The outer walls of the support rod and the sealing blocks are both made of elastic material.

[0015] Preferably, the conveying mechanism includes a feeding assembly disposed outside the spraying mechanism and used to position and convey the side plate to the support mechanism; a first conveying assembly disposed inside the spraying mechanism and connected to the support rod to convey the side plate; a second conveying assembly disposed inside the spraying mechanism and the drying mechanism and connected to the sealing block to convey the side plate; and a recovery assembly disposed outside the spraying mechanism and the drying mechanism and used to recover the support mechanism on the second conveying assembly to the first conveying assembly.

[0016] Preferably, the drive assembly includes a mounting base movably disposed on the support rod, a drive rod with one end disposed on the mounting base and the other end extending to the outside of the support rod, two connecting rods with their ends rotatably connected to the mounting base and the two sealing blocks respectively, a first elastic element disposed on the support rod, a second elastic element disposed on the mounting base, and a guide ramp disposed on the support rod.

[0017] When the mounting base is driven by the recycling assembly to move towards the support rod along with the drive rod, the guide ramp forces the two connecting rods to rotate into the support rod. When the recycling assembly separates from the drive rod, the first elastic element forces the mounting base to move away from the support rod, while the second elastic element forces the two connecting rods to rotate out of the support rod. This causes the two sealing blocks to first move into the bending area between the longitudinal opening and the transverse opening, and then move the two sealing blocks to both ends of the transverse opening.

[0018] Preferably, the support rod is provided with a retractable positioning hole; the first conveying assembly includes a first guide rail disposed at the bottom of the spraying mechanism, a first slide block slidably disposed on the first guide rail, two clamping plates rotatably disposed on the first slide block and used to clamp the side plate, a positioning rod movably disposed on the first slide block and inserted into the positioning hole, and a push rod movably disposed on the first slide block and used to push the drive rod.

[0019] Preferably, the push rod is rotatably mounted on the first slide block; the recycling assembly includes a recycling guide rail with one end connected to the front end of the first guide rail and the other end extending to the rear end of the second conveying assembly, a threaded groove formed in the push rod and threadedly connected to the outer ring surface of the drive rod, an output component disposed below the recycling guide rail, and a discharge plate movably disposed on the output component.

[0020] Preferably, the feeding assembly includes a storage channel disposed outside the spraying mechanism, a positioning groove formed on the storage channel for positioning the side plate corresponding to one end of the longitudinal opening, a discharge port formed on the storage channel, and a feeding plate movably disposed on the storage channel for pushing the side plate toward the first conveying assembly.

[0021] Preferably, a shrinkage hole is formed on the sealing block; the second conveying assembly includes a second guide rail disposed at the top of the spraying mechanism and the drying mechanism, a second slide block slidably disposed on the second guide rail, a connecting rope disposed on the second slide block, an insertion needle disposed at one end of the connecting rope and guiding the connecting rope to the shrinkage hole, and two sets of clamping arms that are openable and closable on the second slide block and are respectively used to clamp the two ends of the insertion needle.

[0022] Preferably, the spraying mechanism includes a spraying chamber, a plurality of first spray guns spaced apart on both sides of the spraying chamber corresponding to the positions of the first conveying component, and a plurality of second spray guns spaced apart on the bottom of the spraying chamber corresponding to the positions of the second conveying component.

[0023] The beneficial effects of this invention are:

[0024] (1) In this invention, the support rod and sealing block of the support mechanism in the support process accurately cover the longitudinal and transverse openings while supporting the side plate, so that the support stability is high and the support effect is good, preventing the paint from entering the internal channel. In the spraying process, the first and second conveying components of the conveying mechanism work together with the support mechanism to automatically switch the support points for two-stage spraying, improving the efficiency of continuous operation. The side plate is suspended by the connecting rope, so that the side plate is suspended without contact, protecting the integrity of the coating and avoiding the blocking phenomenon of traditional brackets. This avoids missed spraying or uneven coating during secondary spraying and ensures that the coating is uniformly heated and cured in the drying process. In addition, the support mechanism automatically returns to the first conveying component through the recycling component in the recycling process, forming a seamless automated production line, significantly improving the production capacity and realizing the recycling of the support mechanism to reduce the cost of consumables.

[0025] (2) In this invention, by setting up a mounting base in conjunction with a connecting rod, a first elastic element, a second elastic element and a guide slope, the mechanical linkage and elastic reset function between the sealing block and the drive rod are realized. Then, the unidirectional linear drive of the drive rod by the recycling component can trigger the opening and closing of the sealing block, simplifying the control system. In addition, the bending area of ​​the side plate itself provides the moving path of the sealing block and the rotation space of the connecting rod, preventing it from getting stuck at the edge of the opening during movement.

[0026] (3) In this invention, by setting a clamping plate to clamp the side plate, the positioning rod can be inserted into the positioning hole for positioning connection. This realizes disassembly and connection, while facilitating the subsequent connection of the second conveying component and supporting the sealing block. In addition, the push rod can be pushed and the threaded connection drive rod forces the mounting base to move. This not only pushes the sealing block to avoid jamming during movement and causing incomplete sealing, but also forces the drive rod to move closer to the support rod. After pushing the side plate and the support rod to separate, the support rod can be re-transported to the first track for recycling with the help of the recycling guide rail.

[0027] In summary, this application has the advantages of good support, good covering effect, and high degree of automation, and is especially suitable for the field of spraying technology. Attached Figure Description

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1-4 As shown, a method for spraying T-shaped profile side panels includes the following steps:

[0042] Step 1: Support process. After the longitudinal opening 11 of the side plate 1 is supported by the support rod 31 of the support mechanism 3, the two sealing blocks 32 on the support rod 31 move to both ends of the transverse opening 12 of the side plate 1, thereby shielding the longitudinal opening 11 and the transverse opening 12.

[0043] Step 2: Spraying process. First, the support rod 31 is connected to the first conveying component 22 of the conveying mechanism 2 to support and convey the side plate 1 for surface spraying. Then, the two sealing blocks 32 are connected to the second conveying component 23 of the conveying mechanism 2 to support and convey the surface of the side plate 1 that is blocked by the first conveying component 22 for secondary spraying.

[0044] In this embodiment, by precisely shielding the longitudinal opening 11 and the transverse opening 12 while supporting the side plate 1 during the support process, the support rod 31 and the sealing block 32 provide high support stability and good support effect, preventing paint from entering the internal channels and ensuring the cleanliness and functionality of the openings. In addition, the first conveying component 22 and the second conveying component 23 of the conveying mechanism 2 work together with the support mechanism 3 to automatically switch the support points for two-stage spraying. First, the surface is sprayed, and then the shielded area is sprayed. This reduces manual intervention, improves continuous operation efficiency, and ensures that all areas of the side plate 1, including the edge of the longitudinal opening 11, are evenly covered, avoiding missed spraying or uneven coating.

[0045] Furthermore, such as Figure 1 as well as Figure 4 As shown, the spraying method for the T-profile side panel 1 also includes the following steps:

[0046] Step 3: Drying process. The second conveying component 23 is connected to two sealing blocks 32 via connecting rope 233, which facilitates the lifting of the side plate 1 for drying and prevents the side plate 1 from being blocked during the drying process.

[0047] Step 4: Recycling process. After the support mechanism 3 on the second conveying component 23 is separated from the dried side plate 1 by the recycling component 24 on the conveying mechanism 2, the recycling component 24 will recycle the separated support mechanism 3 back to the first conveying component 22 and output the processed side plate 1.

[0048] In this embodiment, by suspending the side plate 1 with the connecting rope 233 during the drying process, the side plate 1 is suspended in the air without contact during the drying process, avoiding the obstruction phenomenon that occurs with traditional supports, ensuring that the coating is uniformly heated and cured. The sealing block 32 serves as a lifting fulcrum, avoiding direct clamping of the sprayed surface and protecting the integrity of the coating. In addition, the recycling component 24 in the recycling process quickly separates the support mechanism 3 from the finished side plate 1. The support mechanism 3 automatically returns to the initial position of the first conveying component 22 through the recycling component 24, forming a seamless automated production line, which significantly improves production capacity, reduces coating scratches or contamination caused by manual handling, realizes the recycling of the support mechanism 3 to reduce consumable costs, avoids frequent tooling changes, and reduces manual disassembly and installation time.

[0049] Example 2

[0050] like Figures 2-7 As shown, this application also provides a side panel 1 spraying system, based on a T-profile side panel spraying method in Embodiment 1, comprising:

[0051] The conveying mechanism 2, multiple support mechanisms 3 that are detachably mounted on the conveying mechanism 2 and used to support the side plate 1, a spraying mechanism 4 and a drying mechanism 5 arranged sequentially along the conveying direction of the conveying mechanism 2;

[0052] The support mechanism 3 includes a support rod 31 detachably mounted on the conveying mechanism 2 for supporting the longitudinal opening 11, two sealing blocks 32 movably mounted on both sides of the support rod 31 for blocking the two ends of the transverse opening 12, and a drive assembly 33 mounted on the support rod 31 for driving the sealing blocks 32 to move. The outer walls of the support rod 31 and the sealing blocks 32 are both made of elastic material.

[0053] In this embodiment, the support rod 31 of the support mechanism 3 supports and blocks the longitudinal opening 11 of the side plate 1, and the sealing block 32 is moved by the drive component 33 to block both ends of the transverse opening 12. The support has high stability and good support effect. The support rod 31 and the sealing block 32 are made of elastic material, which can not only fit tightly with the edges of the longitudinal opening 11 and the transverse opening 12 to achieve zero leakage, but also adapt to the tolerance fluctuations of different sized openings, avoiding rigid contact damage to the workpiece. At the same time, the conveying mechanism 2 conveys the insert plate into the spraying mechanism 4 and the drying mechanism 5 in sequence with the support mechanism 3, realizing the automatic flow of the side plate 1 from spraying to drying, reducing manual intervention. During the spraying process, the conveying mechanism 2 first connects the support rod 31 and then connects the sealing block 32, automatically switching the support point to perform two-stage spraying, avoiding missed spraying or uneven coating.

[0054] It should be noted that the detachable structure between the support mechanism 3 and the conveying mechanism 2 allows the support mechanism 3 to be disassembled, replaced, and cleaned after a period of production. In addition, the drying mechanism 5 itself and its installation method are existing technologies and will not be described in detail here.

[0055] Furthermore, such as Figures 4-5 As shown, the conveying mechanism 2 includes a feeding assembly 21 disposed outside the spraying mechanism 4 and used to position and convey the side plate 1 to the support mechanism 3; a first conveying assembly 22 disposed inside the spraying mechanism 4 and connected to and conveying the side plate 1 via a support rod 31; a second conveying assembly 23 disposed inside the spraying mechanism 4 and the drying mechanism 5 and connected to and conveying the side plate 1 via a sealing block 32; and a recovery assembly 24 disposed outside the spraying mechanism 4 and the drying mechanism 5 and used to recover the support mechanism 3 on the second conveying assembly 23 to the first conveying assembly 22.

[0056] In this embodiment, by setting the feeding component 21 to feed the side plate 1 onto the support rod 31 of the first conveying component 22, the side plate 1 is supported and conveyed to the spraying mechanism 4 for surface spraying. Then, in conjunction with the second conveying component 23 and the sealing block 32, the side plate 1 is supported and conveyed to the spraying mechanism 4 for secondary spraying and drying in the drying mechanism 5. With the help of the recycling component 24, the support mechanism 3 after being separated from the finished side plate 1 automatically returns to the initial position of the first conveying component 22, forming a seamless automated production line.

[0057] It should be noted that there are multiple first conveying components 22, second conveying components 23, and recycling components 24 to improve production efficiency. Furthermore, the multiple first conveying components 22, second conveying components 23, and recycling components 24 are all divided into two alternating groups to achieve alternating production, improve production continuity, further improve production efficiency, and improve the compactness of the structure. Group production avoids interference and obstruction between adjacent structures, avoids affecting the smooth operation of the equipment, and also avoids uneven spraying.

[0058] Furthermore, such as Figure 4 as well as Figures 6-10 As shown, the drive assembly 33 includes a mounting base 331 movably disposed on the support rod 31, a drive rod 332 with one end disposed on the mounting base 331 and the other end extending to the outside of the support rod 31, two connecting rods 333 rotatably connected at both ends to the mounting base 331 and two sealing blocks 32 respectively, a first elastic element 334 disposed on the support rod 31, a second elastic element disposed on the mounting base 331, and a guide slope 335 disposed on the support rod 31.

[0059] When the mounting base 331 is driven by the recycling component 24 to move towards the support rod 31 along with the drive rod 332, the guide ramp 335 forces the two connecting rods 333 to rotate into the support rod 31. After the recycling component 24 separates from the drive rod 332, the first elastic element 334 forces the mounting base 331 to move away from the support rod 31, while the second elastic element forces the two connecting rods 333 to rotate out of the support rod 31. This causes the two sealing blocks 32 to first move into the bending area 13 between the longitudinal opening 11 and the transverse opening 12, and then move the two sealing blocks 32 to both ends of the transverse opening 12.

[0060] In this embodiment, by setting the mounting base 331 in conjunction with the connecting rod 333, the first elastic element 334, the second elastic element, and the guide slope 335, the mechanical linkage and elastic reset functions between the sealing block 32 and the drive rod 332 are realized. Then, the unidirectional linear drive of the drive rod 332 by the recycling component 24 can trigger the opening and closing of the sealing block 32, simplifying the control system. The connecting rod 333 pushes the sealing block 32 to move in the transverse opening 12 in a piston-like structure. The bending area 13 of the side plate 1 itself provides the moving path of the sealing block 32 and the rotation space of the connecting rod 333, preventing it from getting stuck at the edge of the opening during movement.

[0061] It should be noted that the second elastic element is not shown in the attached drawings. The first elastic element 334 and the second elastic element are helical springs, torsion springs, etc., and their installation methods are all existing technologies, which will not be described in detail here.

[0062] Furthermore, such as Figures 6-10As shown, the support rod 31 is provided with a retractable positioning hole 311; the first conveying assembly 22 includes a first guide rail 221 disposed at the bottom of the spraying mechanism 4, a first slide block 222 slidably disposed on the first guide rail 221, two clamping plates 223 rotatably disposed on the first slide block 222 and used to clamp the side plate 1, a positioning rod 224 movably disposed on the first slide block 222 and inserted into the positioning hole 311, and a push rod 225 movably disposed on the first slide block 222 and used to push the drive rod 332.

[0063] In this embodiment, by setting the clamping plate 223 to clamp the side plate 1, the positioning rod 224 can be inserted into the positioning hole 311 for positioning connection. This facilitates disassembly and connection, while also making it easier for the subsequent second conveying component 23 to connect and support the sealing block 32. The pushing rod 225 can push the driving rod 332 to force the mounting base 331 to move away from the support rod 31, thus avoiding jamming when the sealing block 32 moves, which would result in incomplete sealing.

[0064] It should be noted that the number of positioning holes 311 is preferably two, in order to adapt to the limited space and improve the stability of positioning.

[0065] Furthermore, such as Figures 4-10 As shown, the push rod 225 is rotatably mounted on the first slide block 222; the recycling assembly 24 includes a recycling guide rail 241 with one end connected to the front end of the first guide rail 221 and the other end extending to the rear end of the second conveying assembly 23, a threaded groove 242 formed in the push rod 225 and threadedly connected to the outer ring surface of the drive rod 332, an output component 243 disposed below the recycling guide rail 241, and a discharge plate 244 movably disposed on the output component 243.

[0066] In this embodiment, by setting the threaded groove 242 to be threadedly connected to the drive rod 332, the drive rod 332 is forced to move closer to the support rod 31. Then, in conjunction with the discharge plate 244, the side plate 1 is pushed to separate from the support rod 31 and output onto the output component 243. With the help of the recycling guide rail 241, the support rod 31 is re-transported to the first track for recycling.

[0067] In detail, during use, the recovery guide rail 241 transports the first slide block 222 to the second conveying assembly 23, and after the clamping plate 223 clamps the side plate 1 on the second conveying assembly 23, the second conveying assembly 23 can be separated from the sealing block 32; next, the moving positioning rod 224 is inserted into the positioning hole 311, and the moving and rotating push rod 225 forces the outer wall of the positioning rod 224 to deform, so that the threaded groove 242 is threadedly connected to the outer ring surface of the drive rod 332, thereby driving the mounting base 331 to move towards the support rod 31 with the drive rod 332. At this time, the guide slope 335 forces the two sealing blocks 32 to move into the support rod 31 with the rotation of the connecting rod 333; then the recovery guide rail 241 transports the first slide block 222 to the top of the output component 243 and separates the clamping plate 223 from the side plate 1, and the moving discharge plate 244 pushes... The side plate 1, which is machined on the moving support rod 31, is separated from the output component 243 for output. Then, the guide rail 241 is used to transport the first slide block 222 to the first guide rail 221. After the side plate 1 is loaded onto the support rod 31 by the feeding component 21, the push rod 225 is moved and rotated to separate the threaded groove 242 from the drive rod 332. The first elastic element 334 forces the mounting seat 331 to move away from the support rod 31, while the second elastic element forces the two connecting rods 333 to rotate out of the support rod 31, thereby moving the two sealing blocks 32 to both ends of the transverse opening 12. Finally, the clamping plate 223 clamps the side plate 1, and the push rod 225 is moved to push the mounting seat 331 to move away from the support rod 31 along with the drive rod 332 until the two sealing blocks 32 move to both ends of the transverse opening 12, after which the drive rod 332 is hidden inside the support rod 31.

[0068] It should be noted that the output component 243 can be a conveyor belt, and both the belt itself and its installation method are existing technologies, which will not be described in detail here.

[0069] Furthermore, such as Figure 13 As shown, the feeding assembly 21 includes a storage channel 211 disposed outside the spraying mechanism 4, a positioning groove 212 formed on the storage channel 211 and used to position one end of the longitudinal opening 11 corresponding to the side plate 1, a discharge port 213 formed on the storage channel 211, and a feeding plate 214 movably disposed on the storage channel 211 and used to push the side plate 1 to move toward the first conveying assembly 22.

[0070] In this embodiment, the side plate 1 is positioned, stored and transported by setting up a storage channel 211 in conjunction with a positioning groove 212, and is pushed by a feeding plate 214 to be positioned and fed onto the first conveying assembly 22 through the discharge port 213.

[0071] It should be noted that the storage channel 211 is an L-shaped structure composed of a vertical section and a horizontal section, and the connection is an arc-shaped structure. This facilitates the side plate 1 to be loaded through the vertical section in the up-down direction, and after passing through the arc-shaped structure, it enters the horizontal section and is positioned and aligned with the first conveying component 22.

[0072] Furthermore, such as Figure 7 as well as Figures 10-12 As shown, a shrinkage hole 321 is formed on the sealing block 32; the second conveying assembly 23 includes a second guide rail 231 disposed at the top of the spraying mechanism 4 and the drying mechanism 5, a second slide block 232 slidably disposed on the second guide rail 231, a connecting rope 233 disposed on the second slide block 232, an insertion needle 234 disposed at one end of the connecting rope 233 and guiding the connecting rope 233 to connect to the shrinkage hole 321, and two sets of clamping arms 235 that are openable and closable on the second slide block 232 and are respectively used to clamp the two ends of the insertion needle 234.

[0073] In this embodiment, by setting two sets of clamping arms 235 to clamp the two ends of the insertion needle 234 respectively, the insertion needle 234 is controlled to pass through the contraction hole 321 during the process of conveying the support mechanism 3 on the first guide rail 221, so that the connecting rope 233 can be connected to the sealing block 32 and the side plate 1 is lifted.

[0074] In detail, during use, a clamping arm 235 separates from the front end of the insertion needle 234. The first guide rail 221 transports the side plate 1 along the direction of the first slide 222 toward the insertion needle 234, causing the front end of the insertion needle 234 to insert into the shrinkage hole 321. Then, as the first guide rail 221 transports the insertion needle 234 out of the shrinkage hole 321, a clamping arm 235 clamps the front end of the insertion needle 234, and the other clamping arm 235 separates from the rear end of the insertion needle 234. Then, as the first guide rail 221 transports the insertion needle 234, it can fully extend out of the sealing block 32. The shrinkage hole 321 can be connected to the connecting rope 233 to lift the side plate 1. Finally, this process is repeated to suspend multiple side plates 1 on the connecting rope 233. After the positioning rod 224 separates from the positioning hole 311, the second guide rail 231 transports the second slide 232 to move within the spraying mechanism 4 and the drying mechanism 5.

[0075] It should be noted that the elastic material used to make the outer wall of the support rod 31 and the sealing block 32 can be rubber or latex, which is existing technology and not shown in the attached figure. Its own elastic deformation ability enables the automatic shrinkage and sealing of the positioning hole 311 and the shrinkage hole 321. In addition, both ends of the connecting rope 233 are provided with insertion needles 234. Correspondingly, the second slide 232 is provided with four clamping arms 235 that clamp the two ends of the two insertion needles 234 respectively. This makes it easy for the recovery component 24 to recover the support mechanism 3 from the end of the connecting rope 233 away from the first conveying component 22, improves the continuity of production, and also facilitates the replacement of the connecting rope 233.

[0076] Furthermore, such as Figure 5 As shown, the spraying mechanism 4 includes a spraying chamber 41, a plurality of first spray guns spaced apart on both sides of the spraying chamber 41 corresponding to the positions of the first conveying component 22, and a plurality of second spray guns 42 spaced apart on the bottom of the spraying chamber 41 corresponding to the positions of the second conveying component 23.

[0077] In this embodiment, a first spray gun is used in conjunction with a second spray gun 42 to achieve two-stage spraying of the side panel 1 in the spraying chamber 41.

[0078] It should be noted that the first spray gun and the second spray gun 42 themselves and their installation methods are existing technologies and will not be described in detail here. In addition, the spraying chamber 41 is equipped with multiple doors that can be opened and closed to separate the various processes and avoid interference between them during production. The doors are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.
