Abstract

This invention relates to the field of profile spraying technology, specifically an aluminum alloy profile spraying device, comprising: a profile conveying mechanism for conveying aluminum alloy profiles along a predetermined route; and two profile placement conveying mechanisms arranged on either side of the conveying route of the profile conveying mechanism. The unloading mechanism not only precisely guides the conveyed profiles, ensuring they fall into the receiving area, but also, after the bottom support portion receives the profile, the top pre-placement portion is in a receiving state. When the bottom support portion lowers the profile, the top pre-placement portion releases the profile as the bottom support portion rises, thus receiving the profile lowered by the top pre-placement portion. The top pre-placement portion continues to receive profiles, achieving continuous receiving and unloading.

Description

Technical Field

[0001] This invention relates to the field of profile spraying technology, specifically to an aluminum alloy profile spraying equipment. Background Technology

[0002] During the processing of aluminum alloy profiles, a spraying process is required. Longer profiles are suspended on a rack and then transported to the spraying chamber by a conveyor chain. The spraying chamber has spray nozzles that move up and down on both sides, allowing for rapid bidirectional spraying.

[0003] However, in the current operation, the profiles need to be placed manually on the top rods or support plates of the suspension frame. This manual operation requires multiple placements, and since the multiple placed profiles are not in the same vertical direction, there will be uneven spraying. Manual operation will affect the spraying efficiency, and the contact area between the support plate and the profile will become a blind spot for spraying. Therefore, the existing material loading method needs to be optimized. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention proposes an aluminum alloy profile spraying equipment.

[0005] The technical solution of this invention is implemented as follows:

[0006] An aluminum alloy profile spraying equipment, comprising:

[0007] A profile conveying mechanism is used to convey aluminum alloy profiles along a predetermined route;

[0008] The profile placement and conveying mechanism consists of two profile placement and conveying mechanisms, which are arranged on both sides of the conveying route of the profile conveying mechanism. The two profile placement and conveying mechanisms are used to convey profiles from both sides to the position of the profile conveying mechanism.

[0009] The unloading mechanism is located on the side of the profile placement and conveying mechanism near the profile conveying mechanism. The unloading mechanism includes a bottom support part and a top pre-placement part. When the bottom support part does not support the profile, the top pre-placement part is in a retracted state. When the bottom support part supports the profile, the top pre-placement part is in an extended state. When the contact foot block on the profile placement and conveying mechanism contacts the bottom support part, the bottom support part is in a retracted state.

[0010] A placement rack mechanism is disposed outside the profile conveying mechanism and directly below the unloading mechanism. The placement rack mechanism is suspended from one end of the profile placement and conveying mechanism by an internal hanging plate. The placement rack mechanism includes a frame portion. A bottom receiving mechanism is disposed below the inner cavity of the frame portion. Multiple trigger support mechanisms are sequentially disposed inside the frame portion and above the bottom receiving mechanism. The bottom receiving mechanism is disposed on a fixed frame fitted inside an opening on the inner side of the frame portion. The bottom receiving mechanism includes a rotating rod. A fixed sleeve is rotatably disposed on the rotating rod by a torsion spring. A support plate is disposed on one side of the surface of the fixed sleeve. A top plate is fixedly connected to the other side of the surface of the fixed sleeve. An elastic sliding plate is disposed on the top of the top plate, and one end of the elastic sliding plate contacts the bottom of the trigger support mechanism. A clamping mechanism is disposed inside the frame portion. An adjusting mechanism is disposed outside the clamping mechanism. The adjusting mechanism is used to move the clamping mechanism, the trigger support mechanism, and the bottom receiving mechanism in opposite directions.

[0011] Furthermore, the profile placement and conveying mechanism includes a conveying device. The contact feet are evenly spaced at the edge of the conveyor belt surface of the conveying device. A centering plate is fixedly connected to the conveying device near the unloading mechanism, and the contact feet pass through the channel reserved in the centering plate. Two fixed seats are fixedly connected to the conveying device near the profile conveying mechanism, and limit plates are provided on the outer sides of the two fixed seats. The limit plates are used to suspend the hanging plate. A guide side plate is provided on one side of the limit plate located on the unloading mechanism, and a vertical limit plate is provided corresponding to the position of the guide side plate. A force-bearing plate that contacts the contact feet is provided on the unloading mechanism.

[0012] Furthermore, the profile conveying mechanism includes two conveying slide rails that pass through the spraying chamber. A sliding sleeve is provided on the conveying slide rail, and a connecting plate is provided on both sides of the sliding sleeve. An adjusting screw is threadedly connected to the connecting plate, and the bottom end of the adjusting screw is threadedly connected to the lower connecting plate. Frame portions are provided on the upper and lower connecting plates.

[0013] Furthermore, the feeding mechanism includes a guide tilting part, the bottom of which is provided with a vertical side plate, the outer side of which is provided with a side corner baffle, and the bottom support part is provided below the inner cavity of the side plate.

[0014] Furthermore, the bottom support portion includes a support seat, one end of which penetrates the side plate and extends to the outside. A sliding rod is provided in the movable opening at the bottom of the support seat, and a return spring is sleeved on the sliding rod. A linkage guide block is fixedly connected to the top of the support seat, and a movable groove is provided on the linkage guide block. A fixed rod passes through the movable groove, and guide rods are provided at both ends of the fixed rod. A sliding rod is provided at both ends of the support seat, and the sliding rod passes through an inclined sliding groove opened in the side plate. A force-bearing plate is fixedly connected to the sliding rod.

[0015] Furthermore, the top pre-placement portion includes a receiving plate, which slides on a sliding plate. The sliding plate is fixedly connected to one side of the inner wall of the side plate. Guide sleeves are provided on both sides of the bottom of the receiving plate, and the guide roller is sleeved in the guide sleeve.

[0016] Furthermore, the trigger support mechanism includes a rotating sleeve elastically rotatably mounted on a fixed frame, a support plate portion fixedly connected to the rotating sleeve, and the support plate portion being in a retracted state. A clamping plate is fixedly connected to the inner side of the rotating sleeve. The clamping plate includes a U-shaped fixing plate, and a U-shaped toothed plate is elastically rotatably connected inside the U-shaped fixing plate. Two elastic telescopic supports are fixedly connected to the top of the clamping plate. A rotating roller is hinged to the top of the elastic telescopic support, and the rotating roller contacts the bottom of the clamping plate above.

[0017] Furthermore, the elastic telescopic support includes a slide bar, with a sliding sleeve fitted at both the upper and lower ends of the slide bar. The lower sliding sleeve is fixedly connected to the top of the card plate. The slide bar is elastically connected to the bottom of the inner wall of the lower sliding sleeve through a compression spring. A pressure chamber is provided between the top of the slide bar and the upper sliding sleeve.

[0018] Furthermore, the adjustment mechanism includes a fixing bar, which is fixedly connected to one side of the clamping mechanism. An inclined slide is provided on the fixing bar, which passes through the sliding bar. A movable handle is fixedly connected to one side of the sliding bar, and the movable handle passes through a movable groove provided on the frame portion.

[0019] Furthermore, the clamping mechanism includes a movable plate with slots on both sides. The U-shaped toothed plate is located within the slots and meshes with a transmission gear within the slots. The movable plate is provided with a unidirectional rotating shaft at both the support plate and the pallet portion. A fixing block is fixedly connected to one end of the rotating shaft, and a contact rubber is fixedly connected to one side of the fixing block.

[0020] The present invention has the following beneficial effects:

[0021] 1. The profile placement and conveying mechanisms on both sides are used to transport the placed profiles to the center. The profiles are located in the middle of the contact feet on both sides. When the profiles move to the unloading mechanism, the centering plates on both sides correct the position of the profiles, keeping them in the middle position and accurately guiding them to the unloading mechanism. After the contact feet pass through the channels reserved in the centering plates, they contact the force plate and provide power to the unloading mechanism, thus ensuring that the profiles can be unloaded and received automatically whenever the force plate passes by. The guide side plates are used to limit the profiles falling from the conveyor belt, so that they fall to the position of the unloading mechanism, improving the accuracy of the fall. In conjunction with the vertical limit plates, the profiles falling from the unloading mechanism can be stably placed on the placement frame mechanism.

[0022] 2. The feeding mechanism not only accurately guides the conveyed profiles to fall into the receiving area, but also allows the bottom support part to receive the profiles, making the top pre-feeding part ready to receive them. When the bottom support part lowers the profiles, the top pre-feeding part releases the profiles as the bottom support part rises. The bottom support part then receives the profiles lowered by the top pre-feeding part, and the top pre-feeding part continues to receive the profiles, thus achieving continuous feeding.

[0023] 3. The bottom receiving mechanism is initially tilted, allowing the falling profile to be controlled by the vertical limiting plate and fall onto it. Under the weight of the profile, the bottom receiving mechanism flattens out, and one end contacts the trigger support mechanism above it, causing it to tilt from its retracted state. This allows the bottom trigger support mechanism to receive the profile. As the profile continues to be received, the profile causes the trigger support mechanism to change from tilted to horizontal. Simultaneously, after receiving the profile, the trigger support mechanism above the receiving position also becomes capable of receiving the profile. This coordinated action allows for bottom-to-top receiving. After receiving the profile, the adjustment mechanism moves the clamping mechanism towards the profile, clamping it. The trigger support mechanism and the bottom receiving mechanism retract synchronously, disengaging from the profile. The clamping mechanism then holds the profile from both sides, achieving automatic loading and unloading. Furthermore, this improves spraying efficiency and eliminates blind spots during painting.

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] See Figures 1 to 19 As shown, an aluminum alloy profile spraying equipment includes:

[0045] The profile conveying mechanism 4 is used to convey aluminum alloy profiles along a predetermined route. The profile conveying mechanism 4 includes two conveying slide rails 402. The conveying slide rails 402 pass through the spraying chamber. A sliding sleeve 401 is provided on the conveying slide rails 402. A connecting plate 403 is provided on both sides of the sliding sleeve 401. An adjusting screw 404 is threadedly connected to the connecting plate 403. The bottom end of the adjusting screw 404 is threadedly connected to the lower connecting plate 403. A frame part 31 is provided on the upper and lower connecting plates 403.

[0046] There are multiple sliding sleeves 401, which are divided into two groups in the height direction. Two sliding sleeves 401 at the same position move synchronously. Specifically, when the sliding sleeves 401 are conveyed, multiple sliding sleeves 401 are moved synchronously through a conveyor chain. The connecting plate 403 is set up so that it can be finely adjusted up and down on the sliding sleeve 401 to adapt to the adjusting screw 404. This allows the adjusting screw 404 to move in the height direction, so that the upper and lower connecting plates 403 can be in a tensioned state, thereby adjusting the overall stability according to the use.

[0047] There are two profile placement and conveying mechanisms 1. The two profile placement and conveying mechanisms 1 are set on both sides of the conveying route of the profile conveying mechanism 4. The two profile placement and conveying mechanisms 1 are used to convey profiles from both sides to the position of the profile conveying mechanism 4.

[0048] The profile placement and conveying mechanism 1 includes a conveying device. Touching feet 101 are evenly spaced at the edge of the conveyor belt surface of the conveying device. A centering plate 102 is fixedly connected to the conveying device near the unloading mechanism 2, and the touching feet 101 pass through the channel reserved in the centering plate 102. Two fixed seats 103 are fixedly connected to the conveying device near the profile conveying mechanism 4, and a limiting plate 104 is provided on the outer side of the two fixed seats 103. The limiting plate 104 is used to suspend the hanging plate 5. A guide side plate 105 is provided on one side of the limiting plate 104 located in the unloading mechanism 2. A vertical limiting plate 6 is provided at the position corresponding to the guide side plate 105. A force plate 101.1 that contacts the touching feet 101 is provided on the unloading mechanism 2.

[0049] The profile placement and conveying mechanisms 1 on both sides are used to convey the placed profiles towards the center. The profiles are positioned between the contact feet 101 on both sides. When the profiles move to the unloading mechanism 2, the centering plates 102 on both sides correct the position of the profiles, keeping them in the center position and accurately guiding them to the unloading mechanism 2. After the contact feet 101 pass through the reserved channels in the centering plate 102, they come into contact with the force plate 101.1, providing power to the unloading mechanism 2, thereby ensuring that the profiles can be unloaded automatically whenever the force plate 101.1 passes by. The guide side plate 105 is used to limit the profiles falling from the conveyor belt, so that they fall into the position of the unloading mechanism 2, which improves the accuracy of the falling. In conjunction with the vertical limiting plate 6, the profiles falling from the unloading mechanism 2 can be stably placed into the position of the placement frame mechanism 3. The limiting plate 104 is set so that when the placement frame mechanism 3 moves to the position of the profile placement and conveying mechanism 1, the hanging plate 5 is pulled upward, so that the limiting plate 104 is below the hanging plate 5. After the hanging plate 5 is released, the hanging plate 5 is locked onto the limiting plate 104.

[0050] The unloading mechanism 2 is located on the side of the profile placement and conveying mechanism 1 near the profile conveying mechanism 4. The unloading mechanism includes a bottom support part 24 and a top pre-placement part 23. When the bottom support part 24 does not support the profile, the top pre-placement part 23 is in a retracted state. When the bottom support part 24 supports the profile, the top pre-placement part 23 is in an extended state. When the contact foot block 101 on the profile placement and conveying mechanism 1 contacts the bottom support part 24, the bottom support part 24 is in a retracted state.

[0051] The feeding mechanism 2 includes a guide tilting part 21, a vertical side plate 22 is provided at the bottom of the guide tilting part 21, a side corner baffle 25 is provided on the outer side of the side plate 22, and a bottom support part 24 is provided below the inner cavity of the side plate 22.

[0052] The bottom support portion 24 includes a support seat 241. One end of the support seat 241 passes through the side plate 22 and extends to the outside. A sliding rod 242 is provided in the movable opening at the bottom of the support seat 241. A return spring 243 is sleeved on the sliding rod 242. A linkage guide block 245 is fixedly connected to the top of the support seat 241. A movable groove 246 is provided on the linkage guide block 245. A fixed rod 247 passes through the movable groove 246. Guide rods 244 are provided at both ends of the fixed rod 247. Sliding rods are provided at both ends of the support seat 241. The sliding rods pass through the inclined sliding groove 221 opened in the side plate 22. A force plate 101.1 is fixedly connected to the sliding rod.

[0053] The bottom support portion 24 is designed with two side support seats 241 extending outwards. The space between the support seats 241 is less than the length of the profile. The support seats 241 can support the profile falling from above. When the profile falls, the two support seats 241 are subjected to the weight of the profile, and the two side support seats 241 move downwards. This compresses the return spring 243, and the sliding rods at both ends of the support seats 241 move to the middle position of the inclined slide groove 221. When the contact foot block 101 contacts the force plate 101.1, the force plate 101.1 causes the sliding rod to move downwards into the inner cavity of the inclined slide groove 221. In this way, the two side support seats 241 can be retracted into the inner cavity of the side plate 22. The two support seats 241 supporting the profile can place the profile on the placement frame mechanism 3 to realize the loading operation.

[0054] The top pre-placement part 23 includes a receiving plate 231, which slides on a sliding plate 232. The sliding plate 232 is fixedly connected to one side of the inner wall of the side plate 22. Guide sleeves 233 are provided on both sides of the bottom of the receiving plate 231, and guide rollers 244 are fitted inside the guide sleeves 233.

[0055] The top pre-placement portion 23 is located above the bottom support portion 24. When the receiving seat 241 moves to the top of the inclined chute 221, the receiving seat 241 is in the outermost position. At this time, the linkage guide block 245 moves upward, so the guide roller 244 on the linkage guide block 245 moves upward in the guide sleeve 233. The guide roller 244 causes the guide sleeve 233 to move inward. Thus, when the receiving seat 241 moves to the topmost position, the two receiving plates 231 are retracted into the side plate. Inside 22, when the receiving seat 241 is subjected to the weight of the profile, the receiving seat 241 will move to the middle position of the inclined slide 221. At this time, the guide rod 244 on the linkage guide block 245 moves downward in the guide sleeve 233. In this way, the guide rod 244 causes the guide sleeve 233 to move outward, and then the receiving plate 231 moves to the outside of the side plate 22. In this way, the side plates 22 on both sides move in opposite directions, so that the upper receiving plate 231 can receive the dropped profile.

[0056] When the contact foot block 101 contacts the force plate 101.1, the sliding rod on the receiving seat 241 moves to a position below the inclined slide groove 221. When the receiving seats 241 on both sides retract, the receiving seats 241 disengage from the profile, and the profile falls. When the contact foot block 101 separates from the force plate 101.1, under the elastic action of the return spring 243, the receiving seat 241 moves to the uppermost position and extends out of the side plate 22. At this time, the receiving plate 231 retracts into the interior of the side plate 22, so that the profile on the receiving plate 231 can fall to the position of the receiving seat 241, thereby enabling continuous feeding operations.

[0057] The movable groove 246 includes a central inclined groove. The top of the central inclined groove is provided with a first transformation groove protruding towards the profile dropping position, and the bottom of the central inclined groove is provided with a second transformation groove protruding outward. The purpose of this arrangement is that when the linkage guide block 245 moves upward, and the fixed rod 247 switches from the central inclined groove to the second transformation groove position, the fixed rod 247 causes the guide rod 244 to move a wide range within the guide sleeve 233. This allows the guide rod 244 to quickly move the guide sleeve 233 into the side plate 22. When the linkage guide block 245 moves downward, and the guide rod 244 moves from the central inclined groove to the first transformation groove, the guide rod 244 first contacts one side of the inner wall of the guide sleeve 233. When the fixed rod 247 switches from the central inclined groove to the first transformation groove position, the fixed rod 247 causes the guide rod 244 to drive the receiving plate 231 to move outward.

[0058] The placement rack mechanism 3 is located outside the profile conveying mechanism 4 and directly below the unloading mechanism 2. The placement rack mechanism 3 is suspended from one end of the profile placement and conveying mechanism 1 by an internal hanging plate 5. The placement rack mechanism 3 includes a frame portion 31. A bottom receiving mechanism 32 is located below the inner cavity of the frame portion 31. Multiple trigger support mechanisms 33 are sequentially arranged inside the frame portion 31 and above the bottom receiving mechanism 32. A clamping mechanism 35 is located inside the frame portion 31. An adjustment mechanism 34 is located outside the clamping mechanism 35, allowing the clamping mechanism 35 to move in opposite directions relative to the trigger support mechanism 33 and the bottom receiving mechanism 32. The profiles clamped by the placement rack mechanisms 3 on both sides are staggered, ensuring that the profiles on both sides do not obstruct each other during spraying by the spraying equipment on both sides.

[0059] The placement rack mechanism 3 is configured such that, in the material receiving state, the bottom material receiving mechanism 32 is initially tilted. This allows the falling profile to be controlled by the vertical limiting plate 6 and fall onto the bottom material receiving mechanism 32. Under the weight of the profile, the bottom material receiving mechanism 32 flattens out, and then one end of the bottom material receiving mechanism 32 contacts the trigger support mechanism 33 above it, causing it to shift from a stored state to a tilted state. This allows the bottom trigger support mechanism 33 to receive the profile. When continuing to receive profiles, the profile... The trigger support mechanism 33 can be changed from an inclined state to a horizontal state. At the same time, after the lower trigger support mechanism 33 receives the material, the trigger support mechanism 33 above the receiving position can be in a receiving state. This linkage can complete the receiving from bottom to top. After the receiving is completed, the adjustment mechanism 34 is operated, which causes the clamping mechanism 35 to move towards the profile to complete the clamping of the profile. Meanwhile, the trigger support mechanism 33 and the bottom receiving mechanism 32 are retracted synchronously and disengaged from the profile. In this way, the clamping mechanism 35 clamps the profile from both sides.

[0060] The bottom receiving mechanism 32 is set on the fixed frame 311 fitted inside the opening 312 on the inner side of the frame part 31. The bottom receiving mechanism 32 includes a rotating rod 321. The rotating rod 321 is rotatably provided with a fixed sleeve 322 by a torsion spring. A support plate 323 is provided on one side of the surface of the fixed sleeve 322. A top plate 324 is fixedly connected to the other side of the surface of the fixed sleeve 322. An elastic sliding plate 325 is provided on the top of the top plate 324, and one end of the elastic sliding plate 325 contacts the bottom of the trigger support mechanism 33.

[0061] The bottom receiving mechanism 32 is designed to receive the first falling profile. When the bottom receiving mechanism 32 is subjected to gravity after receiving the profile, the support plate 323 will rotate to a horizontal state. Then, the fixing sleeve 322 will cause the torsion spring to be in an elastic tightening state. At this time, the rotation of the fixing sleeve 322 will cause the top plate 324 to gradually become vertical. During this process, the elastic sliding plate 325 on the top plate 324 can cause the upper clamping plate 334 to rotate upward, thereby triggering the support mechanism 33 to switch from the storage state to the receiving state. The advantage of this design is that there is a gap between the profile and the placement frame mechanism 3, which ensures that the paint forms a spray at the gap during spraying, thus better adhering to the surface of the profile.

[0062] The trigger support mechanism 33 includes a rotating sleeve 332 that is rotatably mounted on a fixed frame 311, a support plate portion 331 that is fixedly connected to the rotating sleeve 332 and is in a retracted state, a card plate 334 that is fixedly connected to the inner side of the rotating sleeve 332, two elastic telescopic supports that are fixedly connected to the top of the card plate 334, a rotating roller 338 that is hinged to the top of the elastic telescopic supports, and the rotating roller 338 that contacts the bottom of the upper card plate 334.

[0063] The elastic telescopic support includes a slide bar 333, with slide sleeves 334 fitted at both the upper and lower ends of the slide bar 333. The lower slide sleeve 334 is fixedly connected to the top of the clamping plate 334. The slide bar 333 is elastically connected to the bottom of the inner wall of the lower slide sleeve 334 through a compression spring 336. A pressure chamber 337 is provided between the top of the slide bar 333 and the upper slide sleeve 334. With the elastic telescopic support, when the U-shaped fixing plate 3341 rotates upward, the U-shaped fixing plate 3341 causes the slide sleeves 334 at both ends to slide on the slide bar 333. At this time, the pressure chamber 337 is compressed. By moving within the pressure chamber 337, the upper U-shaped fixing plate 3341 can continue to maintain its retracted state. When the profile falls, when the support plate part 331 at this point rotates to a horizontal state, the slide sleeve 334 compresses the compression spring 336 within the slide bar 333. Under the action of the compression spring 336, the upper U-shaped fixing plate 3341 is lifted up and placed in a receiving state.

[0064] The clamping plate 334 includes a U-shaped fixing plate 3341, and a clamping plate 3342 is elastically rotatably connected inside the U-shaped fixing plate 3341.

[0065] When the bottom receiving mechanism 32 completes receiving the material, the trigger support mechanism 33 switches from the storage state to the tilted state. At this time, the profile falling from above can be contacted by the trigger support mechanism 33, so that the pallet part 331 contacts the bottom of the profile and the pallet part 331 is in a horizontal state. At this time, the rotating sleeve 332 rotates, and then the clamping plate 334 rotates. Since the clamping plate 3342 is engaged with the clamping mechanism 35, the clamping plate 3342 remains in a horizontal state. One end of the U-shaped fixing plate 3341 contacts the upper U-shaped fixing plate 3341, lifting the upper U-shaped fixing plate 3341, and then the upper pallet part 331 switches from the storage state to the tilted state, so that it can be in the receiving state.

[0066] The adjustment mechanism 34 includes a fixing bar 341, which is fixedly connected to one side of the clamping mechanism 35. An inclined slide 342 is provided on the fixing bar 341, which passes through the sliding bar 344. A movable handle 343 is fixedly connected to one side of the sliding bar 344, and the movable handle 343 passes through the movable groove provided on the frame part 31.

[0067] After the profile is loaded, the moving handles 343 on both sides are moved at the same time. The moving handles 343 can drive the sliding bar 344 to move in the inclined slide 342, and then the fixing bar 341 drives the clamping mechanism 35 to move out towards the trigger support mechanism 33, and then the trigger support mechanism 33 can move inward.

[0068] The clamping mechanism 35 includes a movable plate 351, with slots on both sides of the movable plate 351. A clamping plate 3342 is located inside the slots and meshes with a transmission gear 352 inside the slots. The movable plate 351 is provided with a unidirectional rotating shaft 353 at both the support plate 323 and the pallet portion 331. A fixing block 354 is fixedly connected to one end of the rotating shaft 353, and a contact rubber 355 is fixedly connected to one side of the fixing block 354.

[0069] The clamping mechanism 35 is configured such that when the adjusting mechanism 34 moves the clamping mechanism 35 toward the profile, the support plate 323 and the support plate portion 331 gradually move inward. When the contact rubber 355 comes into contact with the profile, the support plate 323 and the support plate portion 331 disengage from the profile. In this way, the contact rubber 355 can clamp the profile, and then the profile can rotate during spraying. This allows the profile to be sprayed evenly. Moreover, during spraying, the profile is clamped from both sides, and the surface of the profile can be fully exposed, thus allowing for comprehensive and even spraying.

[0070] In practical use, the profile is placed in the middle of the two side contact foot blocks 101. When the profile moves to the unloading mechanism 2, the two side center plates 102 correct the position of the profile so that it is kept in the middle position and can be accurately guided to the unloading mechanism 2. After the contact foot block 101 passes through the reserved channel of the center plate 102, it contacts the force plate 101.1 and can provide power to the unloading mechanism 2, thereby ensuring that the profile can be unloaded and received by itself whenever the force plate 101.1 passes by. The guide side plate 105 is used to limit the profile falling up and down of the conveyor belt so that it falls into the position of the unloading mechanism 2.

[0071] Among them, the receiving seats 241 on both sides extend outward, and the space between the receiving seats 241 is less than the length of the profile. The receiving seats 241 can receive the profile falling from above. When the profile falls, the two receiving seats 241 are subjected to the weight of the profile, and the two receiving seats 241 on both sides move downward. This compresses the return spring 243, and the sliding rods at both ends of the receiving seats 241 move to the middle position of the inclined slide groove 221. When the contact foot block 101 contacts the force plate 101.1, the force plate 101.1 causes the sliding rod to move downward into the inner cavity of the inclined slide groove 221. In this way, the two receiving seats 241 on both sides can be retracted into the inner cavity of the side plate 22. The two receiving seats 241 supporting the profile can place the profile on the placement frame mechanism 3 to realize the loading operation.

[0072] When the receiving seat 241 moves to the top of the inclined slide 221, the receiving seat 241 is in the outermost position. At this time, the linkage guide block 245 moves upward, so the guide rod 244 on the linkage guide block 245 moves upward in the guide sleeve 233. The guide rod 244 causes the guide sleeve 233 to move inward. When the receiving seat 241 moves to the top position, the two receiving plates 231 are stored in the side plate 22. When the receiving seat 241 is subjected to the weight of the profile, the receiving seat 241 will move to the middle position of the inclined slide 221. At this time, the guide rod 244 on the linkage guide block 245 moves downward in the guide sleeve 233. The guide rod 244 causes the guide sleeve 233 to move outward, and then the receiving plate 231 moves to the outside of the side plate 22. In this way, the two side plates 22 move in opposite directions, so that the upper receiving plate 231 can receive the falling profile.

[0073] When the contact foot block 101 contacts the force plate 101.1, the sliding rod on the receiving seat 241 will move to the position below the inclined slide groove 221. In this way, when the receiving seats 241 on both sides are retracted, the receiving seats 241 will disengage from the profile and the profile will fall. When the contact foot block 101 separates from the force plate 101.1, under the elastic action of the return spring 243, the receiving seat 241 moves to the uppermost position and extends out of the side plate 22. At this time, the receiving plate 231 is retracted into the interior of the side plate 22. In this way, the profile on the receiving plate 231 can fall to the position of the receiving seat 241, thereby enabling continuous feeding operation.

[0074] The bottom receiving mechanism 32 is initially tilted, allowing the falling profile to be contained by the vertical limiting plate 6 and fall onto it. Under the weight of the profile, the bottom receiving mechanism 32 flattens out, and one end of it contacts the trigger support mechanism 33 above it, causing it to shift from a retracted state to a tilted state. This allows the bottom trigger support mechanism 33 to receive the profile. As the profile continues to be received, it allows the trigger support mechanism 33 to... 3. The material is changed from an inclined state to a horizontal state. At the same time, the trigger support mechanism 33 below can be in the receiving state after receiving the material. This linkage can complete the receiving from bottom to top. After receiving the material, the adjustment mechanism 34 is operated. The adjustment mechanism 34 causes the clamping mechanism 35 to move towards the profile to complete the clamping of the profile. Meanwhile, the trigger support mechanism 33 and the bottom receiving mechanism 32 are retracted synchronously and disengaged from the profile. In this way, the clamping mechanism 35 clamps the profile from both sides.

[0075] When the profile enters the spraying chamber, after the contact rubber 355 comes into contact with the profile, the support plate 323 and the support plate part 331 disengage from the profile. In this way, the contact rubber 355 can clamp the profile, and then the profile can rotate during spraying, so that the profile can be sprayed evenly.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
