Description

Technical Field

[0001] The present invention relates to the technical field of spraying, and particularly relates to a spraying method and system for the side plate of a T-shaped profile. Background Art

[0002] Currently, during the processing of metal products, an anti-corrosion coating is usually sprayed on 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 in which a spray gun or a butterfly atomizer is used to disperse into uniform and fine droplets by means of pressure or centrifugal force and apply them to the surface of the object to be coated. The spraying operation has high production efficiency, is suitable for manual operation and industrial automation production, and has a wide range of applications, mainly in the fields of hardware, plastics, furniture, military, ships, etc. It is the most commonly used coating method today.

[0003] The patent document with the patent number CN205791308U discloses a spliced three-way cable tray, including a horizontal through port and a vertical through port arranged in a T shape, and further including a T-shaped bottom plate. The T-shaped bottom plate is fixed with an outer horizontal side plate along the outside of the horizontal through port, an inner horizontal left side plate is fixed at the left end along the inside of the horizontal through port, and an inner horizontal right side plate is fixed at the right end. The T-shaped bottom plate is fixed with a left vertical side plate and a right vertical side plate along both sides of the vertical through port. Among them, the inner horizontal left side plate is connected to the left vertical side plate, and the inner horizontal right side plate is connected to the right vertical side plate. The inner horizontal left side plate, the inner horizontal right side plate, and the outer horizontal side plate are fixed on the transverse edge of the T-shaped bottom plate along the horizontal through port by riveting. The left vertical side plate and the right vertical side plate are fixed on the vertical edge of the T-shaped bottom plate along the vertical through port by riveting. The utility model has a simple and environmentally friendly structure, low disassembly and assembly difficulty, and strong practicability.

[0004] However, during the actual production and spraying process of the side plate of the T-shaped profile, the inventor found that the existing spraying process has the following problems: the existing support structure has poor support effect on the special-shaped plate such as the side plate of the T-shaped profile, manual feeding is required, and the non-spraying surface cannot be covered while supporting, resulting in poor spraying effect. Before spraying, the non-spraying surface is mainly covered by manual shielding, which requires a large amount of manual labor, low automation degree, low production efficiency, and due to the complex shape of the non-spraying surface of the side plate of the T-shaped profile, the covering object does not fit tightly with the base material, and paint will penetrate, causing material waste. Summary of the Invention

[0005] The object of the present invention is to address the deficiencies of the prior art. By precisely shielding the longitudinal and transverse openings while supporting the side plate with the support rod and the sealing block of the support mechanism during the support process, the support stability is high and the support effect is good. In cooperation with the first conveying component and the second conveying component of the conveying mechanism in the spraying process, the support mechanism automatically switches the support points to perform two-stage spraying. The side plate lifted by the connecting rope is suspended without contact, which not only avoids missed spraying or uneven coating during secondary spraying but also ensures uniform heating and curing of the coating during the drying process. At the same time, in the recycling process, the support mechanism automatically returns to the first conveying component through the recycling component, forming a seamless automated production line. Thus, the problems of poor support effect, poor covering effect, and low automation degree in the existing spraying process are solved.

[0006] For the above technical problems, the following technical solution is adopted: A method for spraying the side plate of a T-shaped profile, comprising the following steps: Step 1: Support process. After the support rod of the support mechanism supports the longitudinal opening of the side plate, the two sealing blocks on the support rod respectively move to both ends of the transverse opening of the side plate, thereby shielding the longitudinal opening and the transverse opening. Step 2: Spraying process. First, connect the support rod through the first conveying component of the conveying mechanism to support and convey the side plate for surface spraying. Then, connect the two sealing blocks through the second conveying component of the conveying mechanism to support and convey the surface of the side plate blocked by the first conveying component for secondary spraying.

[0007] Preferably, the method for spraying the side plate of the T-shaped profile further comprises the following steps: Step 3: Drying process. The second conveying component connects the two sealing blocks through a connecting rope to facilitate lifting the side plate for drying, avoiding the side plate being blocked during drying. Step 4: Recycling process. After separating the support mechanism on the second conveying component and the dried side plate through the recycling component on the conveying mechanism, the recycling component reclaims the separated support mechanism onto the first conveying component and outputs the processed side plate.

After the recycling component is separated from the driving rod, the first elastic member forces the mounting seat to move away from the support rod while the second elastic member forces the two connecting rods to rotate out of the support rod, so that the two sealing blocks first move into the bending area between the longitudinal through - opening and the transverse through - opening, and then move to both ends of the transverse through - opening.

[0011] Preferably, the support rod is provided with a position - fixing hole that can be contracted; the first conveying component includes a first guide rail arranged at the bottom inside the spraying mechanism, a first sliding seat slidably arranged on the first guide rail, two clamping plates rotatably arranged on the first sliding seat and used for clamping the side plate, a positioning rod movably arranged on the first sliding seat and inserted into the position - fixing hole, and a pushing rod movably arranged on the first sliding seat and used for pushing the driving rod.

And in cooperation with the bending area of the side plate itself, a moving path for the sealing block and a rotating space for the connecting rod are provided, preventing jamming at the edge of the through port during movement. (3) In the present invention, by clamping the side plate with a clamping plate, the positioning rod can be inserted into the positioning hole for positioning connection, realizing detachable connection and facilitating the subsequent connection and support of the second conveying assembly to the sealing block. In addition, the pushing rod can push and threadedly connect to the driving rod to force the mounting seat to move, which not only pushes the sealing block to avoid incomplete sealing occlusion caused by jamming during movement, but also forces the driving rod to move towards the direction close to the support rod. Then, after the side plate and the support rod are separated, with the assistance of the recovery guide rail, the support rod can be re-conveyed to the first track for recovery.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Embodiment 1 As Figures 1 - 4 shown, a spraying method for the side plate of a T-shaped profile includes the following steps: Step 1: Support process. After the longitudinal through-port 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 respectively move to both ends of the transverse through-port 12 of the side plate 1, thereby shielding the longitudinal through-port 11 and the transverse through-port 12. Step 2: Spraying process. First, the first conveying component 22 of the conveying mechanism 2 is connected to the support rod 31 to support and convey the side plate 1 for surface spraying, and then the second conveying component 23 of the conveying mechanism 2 is connected to the two sealing blocks 32 to support and convey the surface of the side plate 1 blocked by the first conveying component 22 for secondary spraying.

[0031] In this embodiment, by accurately shielding the longitudinal through-port 11 and the transverse through-port 12 while the support rod 31 and the sealing blocks 32 support the side plate 1 in the support process, the support stability is high, the support effect is good, preventing the paint from entering the internal channels, ensuring the cleanliness and functionality of the through-ports, and supplemented by the cooperation of the first conveying component 22 and the second conveying component 23 of the conveying mechanism 2 with the support mechanism 3 to automatically switch the support points in the spraying process, for two-stage spraying, first surface spraying, and then spraying of the blocked area, reducing manual intervention, improving the continuous operation efficiency, ensuring uniform coverage of all areas of the side plate 1 including the edge of the longitudinal through-port 11, and avoiding missed spraying or uneven coating.

[0032] Further, as Figure 1 and Figure 4 shown, the spraying method for the side plate 1 of the T-shaped profile further includes the following steps: Step 3: Drying process. The second conveying component 23 is connected to the two sealing blocks 32 through the connecting rope 233, facilitating lifting the side plate 1 for drying and avoiding the side plate 1 being blocked during drying. Step 4: Recycling process. After the support mechanism 3 on the second conveying component 23 is separated from the side plate 1 after drying by the recycling component 24 on the conveying mechanism 2, the recycling component 24 recycles the separated support mechanism 3 back onto the first conveying component 22 and outputs the processed side plate 1.

[0033] In this embodiment, during the drying process, the side plate 1 is lifted by the connecting rope 233, so that the side plate 1 is suspended and has no contact during drying, avoiding the shielding phenomenon of traditional brackets, ensuring that the coating is evenly heated and cured, and the sealing block 32 serves as a lifting fulcrum to avoid directly clamping the sprayed surface, protecting the integrity of the coating. In addition, in the recycling process, the recycling component 24 quickly separates the support mechanism 3 from the finished side plate 1. The support mechanism 3 automatically returns to the initial station of the first conveying component 22 through the recycling component 24, forming a seamless automated production line, significantly improving production capacity, reducing coating scratches or contamination caused by manual handling, realizing the recycling of the support mechanism 3 to reduce consumable costs, avoiding frequent replacement of tooling, and reducing manual disassembly and installation time.

[0034] Embodiment 2 As Figures 2 - 7 shown, the present application also provides a side plate 1 spraying system, based on a T-shaped profile side plate spraying method in Embodiment 1, including: A conveying mechanism 2, a plurality of support mechanisms 3 detachably arranged at intervals on the conveying mechanism 2 and used to support the side plate 1, a spraying mechanism 4 and a drying mechanism 5 arranged in sequence along the conveying direction of the conveying mechanism 2; The support mechanism 3 includes a support rod 31 detachably arranged on the conveying mechanism 2 and used to support the longitudinal through hole 11, two sealing blocks 32 movably arranged on both sides of the support rod 31 and respectively used to block both ends of the transverse through hole 12, and a driving component 33 arranged on the support rod 31 and used to drive the sealing block 32 to move. The outer walls of the support rod 31 and the sealing block 32 are both made of elastic materials.

[0035] In this embodiment, the support rod 31 of the support mechanism 3 is set to support and block the longitudinal through hole 11 of the side plate 1, and the driving component 33 is used to drive the sealing block 32 to move and block both ends of the transverse through hole 12. The support has high stability and good support effect. The support rod 31 and the sealing block 32 are made of elastic materials, which can not only closely fit the edges of the longitudinal through hole 11 and the transverse through hole 12 to achieve zero-leakage shielding, but also adapt to the tolerance fluctuations of through holes of different sizes, avoiding rigid contact from damaging the workpiece. At the same time, the conveying mechanism 2 is used to convey the plug board to enter the spraying mechanism 4 and the drying mechanism 5 in sequence with the support mechanism 3, realizing the full-process automatic transfer of the side plate 1 from spraying to drying, reducing manual intervention. During the spraying process, the conveying mechanism 2 first connects to the support rod 31 and then to the sealing block 32, automatically switching the support points for two-stage spraying to avoid missed spraying or uneven coating.

[0036] It should be noted that the detachable structure between the support mechanism 3 and the conveying mechanism 2 enables 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 both prior arts and will not be elaborated here in detail.

[0037] Furthermore, as Figures 4 - 5 shown, the conveying mechanism 2 includes a loading component 21 arranged outside the spraying mechanism 4 and used for positioning and conveying the side plate 1 onto the support mechanism 3, a first conveying component 22 arranged inside the spraying mechanism 4 and connected and conveying the side plate 1 through the support rod 31, a second conveying component 23 arranged inside the spraying mechanism 4 and the drying mechanism 5 and connected and conveying the side plate 1 through the sealing block 32, and a recycling component 24 arranged outside the spraying mechanism 4 and the drying mechanism 5 and used for recycling the support mechanism 3 on the second conveying component 23 to the first conveying component 22.

[0038] In this embodiment, the side plate 1 is loaded onto the support rod 31 of the first conveying component 22 through the loading component 21, so as to support and convey the side plate 1 for surface spraying inside the spraying mechanism 4. Then, in cooperation with the second conveying component 23 to connect the sealing block 32, it realizes supporting and conveying the side plate 1 for secondary spraying inside the spraying mechanism 4 and drying inside the drying mechanism 5 in sequence. With the assistance of the recycling component 24, the support mechanism 3 separated from the finished side plate 1 automatically returns to the initial working position of the first conveying component 22, forming a seamless automated production line.

[0039] It should be noted that the number of the first conveying component 22, the second conveying component 23 and the recycling component 24 is multiple, which improves the production efficiency. And the multiple first conveying components 22, second conveying components 23 and recycling components 24 are divided into two groups arranged alternately, realizing alternate production, improving the continuity of production, further improving the production efficiency, and while improving the compactness of the structure, the grouped production avoids interference and shielding between adjacent structures, avoids affecting the smooth operation of the equipment, and also avoids uneven spraying.

[0040] Furthermore, as Figure 4 and Figures 6 - 10 shown, the driving component 33 includes a mounting seat 331 movably arranged on the support rod 31, a driving rod 332 with one end arranged on the mounting seat 331 and the other end extending outside the support rod 31, two connecting rods 333 with both ends rotatably connected to the mounting seat 331 and the two sealing blocks 32 respectively, a first elastic member 334 arranged on the support rod 31, a second elastic member arranged on the mounting seat 331, and a guiding inclined surface 335 arranged on the support rod 31; When the mounting seat 331 is driven by the recycling component 24 to move along the driving rod 332 towards the support rod 31, the guiding inclined surface 335 forces the two connecting rods 333 to rotate into the support rod 31. After the recycling component 24 is separated from the driving rod 332, the first elastic member 334 forces the mounting seat 331 to move away from the support rod 31, and at the same time, the second elastic member forces the two connecting rods 333 to rotate out of the support rod 31. As a result, the two sealing blocks 32 first move to the bending area 13 between the longitudinal through-port 11 and the transverse through-port 12, and then move to both ends of the transverse through-port 12.

[0041] In this embodiment, by arranging the mounting seat 331 in cooperation with the connecting rod 333, the first elastic member 334, the second elastic member and the guiding inclined surface 335, the mechanical linkage and elastic reset functions between the sealing block 32 and the driving rod 332 are realized. Furthermore, by the one-way linear drive of the driving rod 332 by the recycling component 24, the retraction and extension of the sealing block 32 can be triggered, simplifying the control system. The connecting rod 333 pushes the sealing block 32 to move in the transverse through-port 12 similar to a piston structure, and cooperates with the bending area 13 of the side plate 1 itself to provide the moving path of the sealing block 32 and the rotating space of the connecting rod 333, preventing jamming at the edge of the through-port during movement.

[0042] It should be noted that the second elastic member is not shown in the drawings. The first elastic member 334 and the second elastic member are spiral springs, torsion springs, etc. Their structures and installation methods are all prior arts and will not be elaborated here in detail.

[0043] Furthermore, as Figures 6 - 10 shown, the support rod 31 is provided with a retractable positioning hole 311; the first conveying component 22 includes a first guide rail 221 arranged at the inner bottom of the spraying mechanism 4, a first sliding seat 222 slidably arranged on the first guide rail 221, two clamping plates 223 rotatably arranged on the first sliding seat 222 and used for clamping the side plate 1, a positioning rod 224 movably arranged on the first sliding seat 222 and inserted into the positioning hole 311, and a pushing rod 225 movably arranged on the first sliding seat 222 and used for pushing the driving rod 332.

[0044] In this embodiment, by arranging the clamping plates 223 to clamp the side plate 1, the positioning rod 224 can be inserted into the positioning hole 311 for positioning connection, realizing detachable connection and facilitating the subsequent connection and support of the second conveying component 23 to the sealing block 32, and enabling the pushing rod 225 to push the driving rod 332 to force the mounting seat 331 to move away from the support rod 31, avoiding incomplete sealing caused by jamming during the movement of the sealing block 32.

[0045] It should be noted that the number of the positioning holes 311 is preferably two to adapt to the limited space and improve the positioning stability.

[0046] Further, as Figures 4 - 10 shown, the push rod 225 is rotatably arranged on the first sliding seat 222; the recovery assembly 24 includes a recovery 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 thread groove 242 formed in the push rod 225 and threadedly connected to the outer circumferential surface of the driving rod 332, an output member 243 arranged below the recovery guide rail 241, and a discharge plate 244 movably arranged on the output member 243.

[0047] In this embodiment, during the process of arranging the thread groove 242 to be threadedly connected to the driving rod 332, it is realized to force the driving rod 332 to move towards the direction close to the support rod 31. Furthermore, in cooperation with the discharge plate 244, after the side plate 1 is pushed to be separated from the support rod 31 onto the output member 243 for output, with the assistance of the recovery guide rail 241, the support rod 31 can be re-conveyed onto the first track to achieve recovery.

[0048] Specifically, during use, the recovery guide rail 241 conveys the first sliding seat 222 to the second conveying assembly 23. After the side plate 1 on the second conveying assembly 23 is clamped by the clamping plate 223, the second conveying assembly 23 can be separated from the sealing block 32. Secondly, the moving positioning rod 224 is inserted into the positioning hole 311, and the push rod 225 is moved and rotated to force the outer wall of the positioning rod 224 to deform, so that the thread groove 242 can be threadedly connected to the outer circumferential surface of the driving rod 332. Then, the mounting seat 331 is driven to move towards the direction close to the support rod 31 along with the driving rod 332. At this time, the guiding inclined surface 335 forces the two sealing blocks 32 to move into the support rod 31 respectively along with the rotation of the connecting rod 333. Then, after the recovery guide rail 241 conveys the first sliding seat 222 to directly above the output member 243 and separates the clamping plate 223 from the side plate 1, the discharge plate 244 is moved to push the processed side plate 1 on the support rod 31 to be separated onto the output member 243 for output. Then, the recovery guide rail 241 conveys the first sliding seat 222 onto the first guide rail 221. After the side plate 1 is loaded onto the support rod 31 by the feeding assembly 21, the push rod 225 is moved and rotated to separate the thread groove 242 from the driving rod 332. The first elastic member 334 forces the mounting seat 331 to move away from the support rod 31, and at the same time, the second elastic member forces the two connecting rods 333 to rotate out of the support rod 31, so that the two sealing blocks 32 move towards both ends of the transverse through-port 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 driving rod 332. Until the two sealing blocks 32 move to both ends of the transverse through-port 12, the driving rod 332 can be hidden inside the support rod 31.

[0049] It should be noted that the output member 243 can be a conveyor belt, and its itself and the installation method are both prior arts, and will not be elaborated in detail here.

[0050] Furthermore, as Figure 13 shown, the loading component 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 corresponding longitudinal through-port 11 of 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 towards the first conveying component 22.

[0051] In this embodiment, by providing the storage channel 211 in cooperation with the positioning groove 212, the positioning storage and conveying of the side plate 1 are realized, and in cooperation with the feeding plate 214, the side plate 1 can be pushed to be positioned and fed onto the first conveying component 22 through the discharge port 213.

[0052] 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 part is an arc structure, which is convenient for the side plate 1 to be loaded in the vertical direction through the vertical section, and after passing through the arc structure, it enters the horizontal section to be positioned and aligned with the first conveying component 22.

[0053] Furthermore, as Figure 7 and Figures 10 - 12 shown, a shrinkage hole 321 is formed on the sealing block 32; the second conveying component 23 includes a second guide rail 231 disposed at the inner top of the spraying mechanism 4 and the drying mechanism 5, a second sliding seat 232 slidably disposed on the second guide rail 231, a connecting rope 233 disposed on the second sliding seat 232, an insertion needle 234 disposed at one end of the connecting rope 233 and guiding the connecting rope 233 to be connected to the shrinkage hole 321, and two sets of clamping arms 235 opened and closed on the second sliding seat 232 and respectively used to clamp both ends of the insertion needle 234.

[0054] In this embodiment, by providing two sets of clamping arms 235 to clamp both ends of the insertion needle 234 respectively, during the process of the first guide rail 221 conveying and supporting the mechanism 3, the insertion needle 234 is controlled to pass through the shrinkage hole 321, so that the connecting rope 233 can be connected to the sealing block 32, and the side plate 1 is lifted.

[0055] Specifically, during use, one clamping arm 235 is separated from the front end of the insertion needle 234. The first guide rail 221 conveys the side plate 1, and the first sliding seat 222 moves in the direction of the insertion needle 234, causing the front end of the insertion needle 234 to be inserted into the shrinkage hole 321. Then, with the conveyance of the first guide rail 221, when the insertion needle 234 extends out of the shrinkage hole 321, one clamping arm 235 clamps the front end of the insertion needle 234, and the other clamping arm 235 is separated from the rear end of the insertion needle 234. Then, with the conveyance of the first guide rail 221, the insertion needle 234 fully extends out of the sealing block 32, the shrinkage hole 321 is connected to the connecting rope 233 to lift the side plate 1. Finally, multiple side plates 1 are hung on the connecting rope 233 in this way, and after the positioning rod 224 is moved to be separated from the positioning hole 311, the second guide rail 231 conveys the second sliding seat 232 to move within the spraying mechanism 4 and the drying mechanism 5.

[0056] It should be noted that the elastic material for making the outer walls of the support rod 31 and the sealing block 32 can be rubber or latex, which is prior art and not shown in the drawings. Its own elastic deformation ability enables the automatic shrinkage and sealing of the positioning hole 311 and the shrinkage hole 321. In addition, insertion needles 234 are provided at both ends of the connecting rope 233. Correspondingly, four clamping arms 235 for clamping the two ends of the two insertion needles 234 are provided on the second sliding seat 232 respectively. This facilitates the recovery assembly 24 to recover the support mechanism 3 from the end of the connecting rope 233 far from the first conveying assembly 22, improves the continuity of production, and also facilitates the replacement of the connecting rope 233.

[0057] Furthermore, as Figure 5 shown, the spraying mechanism 4 includes a spraying chamber 41, a plurality of first spraying guns spaced apart and disposed on both sides of the spraying chamber 41 corresponding to the position of the first conveying assembly 22, and a plurality of second spraying guns 42 spaced apart and disposed at the bottom of the spraying chamber 41 corresponding to the position of the second conveying assembly 23.

[0058] In this embodiment, by setting the first spraying gun in cooperation with the second spraying gun 42, two-stage spraying of the side plate 1 is achieved in the spraying chamber 41.

[0059] It should be noted that the first spraying gun and the second spraying gun 42 themselves and their installation methods are prior art and will not be elaborated in detail here. In addition, a plurality of openable chamber doors are provided in the spraying chamber 41 to separate each process and avoid interference with each other during production. The chamber doors are prior art and not shown in the drawings, and will not be elaborated in detail here.
