Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a powder spraying and curing device. Background Technology

[0002] Powder coating equipment is a core component of the powder coating process, consisting mainly of two key parts: a powder spraying system and a curing system. The powder spraying system is responsible for uniformly spraying powder coating onto the workpiece surface, while the curing system heats and cures the sprayed workpiece, causing the powder coating to melt and adhere to the workpiece surface to form a coating film.

[0003] However, traditional operating methods often separate powder coating and curing into two separate devices. In the powder coating stage, due to insufficient equipment sealing, dust often scatters everywhere, affecting the working environment, potentially threatening the health of operators, and reducing the uniformity and quality of the coating. Therefore, we propose a powder coating and curing device. Utility Model Content

[0012] Furthermore, the first baffle has four arc-shaped grooves on the side near the negative pressure suction device, and several blowers are mounted on the arc-shaped grooves. The blowers are fixedly connected to the first baffle. The second baffle has a limit block fixedly connected on the side near the connecting column.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figure 1-10 This utility model provides a technical solution:

[0031] A powder spraying and curing device includes a frame assembly 2, a top plate assembly 1 on the frame assembly 2, lifting doors 3 fixedly connected to both sides of the frame assembly 2, and an opening and closing baffle 4 inside the frame assembly 2.

[0032] The top plate assembly 1 includes a top plate 12, a movable assembly 11 is provided on the top plate 12, and powder spraying assemblies 13 are provided on both sides of the movable assembly 11, with the powder spraying assemblies 13 located below the movable assembly 11.

[0033] The moving assembly 11 includes a top cover 111, which is fixedly connected to a top plate 12. A first motor 112 is housed inside the top cover 111 and is fixedly connected to the top of the top cover 111. The drive shaft of the first motor 112 is fixedly connected to a first track wheel 113. A second track wheel 114 is located on the front side of the first track wheel 113 and is connected to the top plate 12 via a rotating shaft. A movable track 115 is fitted over the first track wheel 113 and the second track wheel 114. Several connecting parts 116 are mounted on the track 115. A first limiting block 117 is located below the connecting parts 116. A chain 118 is fixedly connected below the first limiting block 117, and an S-shaped hook 119 is hung below the chain 118. Two rows of infrared radiation lamps 121 are fixedly installed under the top plate 12. A first limiting groove 122 is provided under the top plate 12 for the first limiting block 117 to slide. The first motor 112, installed inside the top cover 111, drives the first track wheel 113 to rotate. This action, in turn, causes the track 115 to move smoothly along the track of the first track wheel 113 and the second track wheel 114. The movement of the track 115 drives the connected connecting piece 116 to move synchronously, and the connecting piece 116 pulls the first limiting block 117 to slide smoothly along the preset first limiting groove 122. As the first limiting block 117 slides, it further drives the chain 118 to move, and the transmission of the chain 118 ultimately drives the movement of the S-shaped hook 119. The user only needs to suspend the workpiece on the S-shaped hook 119, and through this series of linked mechanical actions, the workpiece can be easily sent into the equipment, realizing the automation and convenience of workpiece transportation.

[0034] The powder spraying assembly 13 includes a cylinder 131, which is fixedly connected to the top plate 12. A crossbar 132 is fixedly connected to the piston rod of the cylinder 131. Several first connecting rods 133 are fixedly connected to the side of the crossbar 132 near the S-shaped hook 119. Each first connecting rod 133 is fixedly connected to a nozzle 134. The cylinder 131 drives the crossbar 132 to move linearly through the extension and retraction of its piston rod. This movement, in turn, causes the first connecting rods 133 connected to the crossbar 132 to move accordingly, and the movement of the first connecting rods 133 directly causes a change in the position of the nozzle 134. In other words, the piston rod of the cylinder 131, through this series of mechanical linkages, drives the nozzle 134 to move up and down. During this up-and-down movement, the nozzle 134 can complete uniform and multiple powder spraying operations, ensuring the uniformity and efficiency of the spraying effect.

[0035] The frame component 2 includes a base plate 21, with side plates 22 fixedly connected to both sides of the base plate 21, and two rows of negative pressure suction devices 211 installed on the base plate 21.

[0036] The lifting door 3 includes a first baffle 31, which is fixedly connected to the base plate 21. A second baffle 32, which can be raised and lowered, is provided inside the first baffle 31. A lifting assembly 33 is fixedly connected to the right side of the second baffle 32, and a connecting column 34 is provided on the left side of the second baffle 32. Four arc-shaped sliding grooves 311 are provided on the side of the first baffle 31 near the negative pressure suction device 211. Several blowers 35 are mounted on the arc-shaped sliding grooves and are fixedly connected to the first baffle 31. A limit block 321 is fixedly connected to the side of the second baffle 32 near the connecting column 34. A second limiting groove 341, which allows the limit block 321 to move up and down, is provided on the side of the connecting column 34 near the second baffle 32. The lifting assembly 33 includes a second connecting rod 331. A second motor 332 is fixedly connected to the inner bottom plate of the second connecting rod 331. A lead screw 333 is fixedly connected to the drive shaft of the second motor 332. Two lead screw nuts 335 are sleeved on the lead screw 333. The lead screw nuts 335 are fixedly connected to a second baffle 32. A lifting groove 334 is provided on the side of the second connecting rod 331 near the second baffle 32, allowing the lead screw nuts 335 to move up and down. The second motor 332 installed inside the second connecting rod 331 drives the lead screw 333 to rotate. This rotation further causes the lead screw nuts 335 to move linearly along the lifting groove 334. As the lead screw nuts 335 move, they drive the limiting block 321 on the second baffle 32, allowing the limiting block 321 to slide up and down along the pre-set second limiting groove 341 inside the connecting column 34. This design not only allows the second baffle 32 to move flexibly up and down within the range of the first baffle 31, but also effectively prevents the lead screw nut 335 from slipping on the lead screw 333 through the cooperation of the limiting block 321 and the second limiting groove 341, thus ensuring the stability and reliability of the entire mechanism.

[0037] The opening / closing baffle 4 includes two first rotating shafts 41, with a second rotating shaft 47 positioned between them. Both the first and second rotating shafts 41 are fixedly connected to the first baffle 31. A baffle 42 is rotatably mounted between the first and second rotating shafts 41 and 47. A second limiting block 48 is fixedly connected to the side of the baffle 42 away from the first and second rotating shafts 41 and 47, and the second limiting block 48 is located on the side closer to the first baffle 31. A fixing block 46 is fixedly connected to the side of the baffle 42 closer to the first baffle 31. The opening / closing baffle 4 includes two symmetrical third motors 43, which are fixedly connected to the base plate 21. The drive shafts of the third motors 43 are fixedly connected to a first rotating rod 44. The first rotating rod 44 is rotatably connected to two second rotating rods 45, which are V-shaped. The second rotating rods 45 are rotatably connected to the fixing block 46. An arc-shaped slide groove 311 matches the second limiting block 48. When the third motor 43 starts and drives the first rotating rod 44 to rotate, this rotation causes the second rotating rod 45 to move downwards via mechanical linkage. Subsequently, the second rotating rod 45, through the connection of the fixing block 46, causes the baffle 42 to rotate around the first rotating axis 41 and the second rotating axis 47, thereby realizing the opening operation of the baffle 42. Conversely, by adjusting the rotation direction of the third motor 43, the first rotating rod 44 can be driven to rotate in the opposite direction, thereby closing the baffle 42. During the rotation of the baffle 42, the second limiting block 48 installed on it slides along the preset arc-shaped slide groove 311 on the first baffle 31. This design not only makes the opening and closing action of the baffle 42 smoother, but also precisely limits the opening and closing angle of the baffle 42 through the cooperation of the second limiting block 48 and the arc-shaped slide groove 311. In particular, when the second limiting block 48 moves to the top of the arc-shaped slide groove 311, the baffle 42 will be in a completely closed state.

[0038] It should be noted that when the baffle 42 is open, it takes on a V-shape. This design facilitates the collection of excess powder along the V-shaped structure during powder spraying, thereby improving powder collection efficiency. When the baffle 42 is closed, it effectively isolates the heat source, protecting the powder below from melting at high temperatures and ensuring powder quality and stability.

[0039] The second motor 332, installed inside the second connecting rod 331, is activated, driving the lead screw 333 to rotate. This rotation further causes the lead screw nut 335 to move linearly along the lifting groove 334. As the lead screw nut 335 moves, it actuates the limiting block 321 on the second baffle 32, allowing the limiting block 321 to slide up and down along the pre-set second limiting groove 341 inside the connecting column 34. This design not only allows the second baffle 32 to move flexibly up and down within the range of the first baffle 31, but also effectively prevents the lead screw nut 335 from slipping on the lead screw 333 through the cooperation of the limiting block 321 and the second limiting groove 341, ensuring the stability and reliability of the entire mechanism. The second motor 332 then lowers the second baffle 32 into the first baffle 31.

[0040] The first motor 112 installed inside the top cover 111 is activated, driving the first track wheel 113 to rotate. This action, in turn, causes the track 115 to move smoothly along the track of the first track wheel 113 and the second track wheel 114. The movement of the track 115 drives the connected connecting piece 116 to move synchronously, and the connecting piece 116 pulls the first limiting block 117 to slide smoothly along the preset first limiting groove 122. As the first limiting block 117 slides, it further drives the chain 118 to move, and the transmission of the chain 118 ultimately drives the movement of the S-shaped hook 119. The user only needs to suspend the workpiece on the S-shaped hook 119, and through this series of linked mechanical actions, the workpiece can be easily sent into the equipment, realizing the automation and convenience of workpiece transportation.

[0041] The lifting door 3 is then closed, sealing the interior of the equipment. The third motor 43 is started, driving the first rotating rod 44 to rotate. This rotation, through mechanical linkage, moves the second rotating rod 45 downwards. Subsequently, the second rotating rod 45, connected by the fixing block 46, causes the baffle 42 to rotate around the first rotating axis 41 and the second rotating axis 47, thus opening the baffle 42. During the rotation of the baffle 42, the second limiting block 48 installed on it slides along the pre-set arc-shaped groove 311 on the first baffle 31. This design not only makes the opening and closing of the baffle 42 smoother but also precisely limits the opening and closing angle of the baffle 42 through the cooperation of the second limiting block 48 and the arc-shaped groove 311. When the baffle 42 is open, its shape forms a V-shape. This design facilitates the collection of excess powder along the V-shaped structure during powder spraying, thereby improving powder collection efficiency.

[0042] Then, cylinder 131 is activated, which drives the horizontal bar 132 to move linearly through the extension and retraction of its piston rod. This movement, in turn, causes the first connecting rod 133 connected to the horizontal bar 132 to move accordingly, and the movement of the first connecting rod 133 directly causes the position change of the nozzle 134. That is, through this series of mechanical linkages, the piston rod of cylinder 131 realizes the up-and-down reciprocating drive of the nozzle 134. During the up-and-down movement, the nozzle 134 can complete uniform and multiple powder spraying operations, ensuring the uniformity and efficiency of the spraying effect. During the powder spraying process, the negative pressure suction device 211 works continuously, continuously sucking up powder from the V-shaped port and collecting it at the bottom of the equipment for subsequent recycling.

[0043] After the powder spraying is completed, the negative pressure suction device 211, cylinder 131 and nozzle 134 are turned off. Then, by adjusting the rotation direction of the third motor 43, the first rotating rod 44 is driven to rotate in the opposite direction, thereby closing the baffle 42. When the second limit block 48 moves to the top of the arc-shaped slide groove 311, the baffle 42 will be in a fully closed state.

[0044] Then, the infrared radiation lamp 121 is turned on to heat the workpiece with infrared radiation, completing the powder curing. Meanwhile, the blower 35 continuously blows air to rapidly circulate the hot air and accelerate the curing speed.

[0045] Once the workpiece has cured, the lifting door is opened, and the first motor 112 is started. It drives the workpiece to move to the lifting door on the other side, where the worker removes the processed workpiece, completing the powder coating and curing operation.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
