Detailed Implementation
[0032] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0033] This utility model discloses a powder spraying device, such as... Figure 1 and Figure 2 As shown, it includes a powder spraying unit 1 and a guiding unit 2 connected to each other. The guiding unit 2 is a sheet workpiece guiding mechanism, including a correction component 3, a guide roller group 4 and a fixed seat. The fixed seat includes a first side seat 51 and a second side seat 52 arranged opposite to each other, forming a correction channel between them.
[0034] The correction assembly 3 includes a first arc-shaped guide 31, a first mounting bracket 32, a second arc-shaped guide 33, and a second mounting bracket 34, each disposed within the correction channel. The first arc-shaped guide 31 is vertically adjustable and mounted on the first mounting bracket 32. The first mounting bracket 32 is horizontally adjustable and mounted on the first side seat 51. The second arc-shaped guide 33 is vertically adjustable and mounted on the second mounting bracket 34. The second mounting bracket 34 is horizontally adjustable and mounted on the second side seat 51. A workpiece movement channel is formed between the first arc-shaped guide 32 and the second arc-shaped guide 33. The first arc-shaped guide 32 and the second arc-shaped guide 33 are mirror-oriented with respect to the workpiece's movement direction and are arranged in a figure-eight shape, forming a flared end 35 and a narrow end 36. The direction from the flared end 35 to the narrow end 36 is the workpiece movement direction. After the workpiece is input through the flared end 35, it is corrected and output through the narrow end 36. The size of the narrow end 36 is adapted to the thickness of the workpiece.
[0035] The guide roller group 4 is connected to the narrow end 36, and the guide roller group 4 forms a workpiece clamping gap 41. The workpiece moving channel and the workpiece clamping gap 41 are located on the same straight line.
[0036] This utility model discloses a powder spraying device, applicable to sheet-like workpieces such as those traditionally hung. The sheet-like workpiece is hung on a hook, which is mounted on a sliding block on a moving track. The sliding block moves within a set track, which is located at the top, allowing the workpiece to be hoisted and moved. In use, when the sheet-like workpiece moves to the powder spraying device, it enters through the flared end 35. Along the workpiece's movement direction (i.e., from the flared end 35 to the narrow end 36), the workpiece movement channel gradually narrows. If the workpiece is misaligned, the guiding unit 2 corrects and guides it, ensuring that the workpiece exiting from the narrow end 36 is in a basically upright position. Then, the corrected workpiece enters the guide roller group 4, which slightly clamps the workpiece, allowing it to enter the powder spraying unit 1 flat for powder spraying, thus improving the uniformity of powder spraying.
[0037] In a preferred embodiment, the first arc-shaped guide 31 is an arc-shaped strip or an arc-shaped plate, and the second arc-shaped guide 33 is an arc-shaped strip or an arc-shaped plate. The structure of the second arc-shaped guide 33 is the same as that of the first arc-shaped guide 31. In this embodiment, the first arc-shaped guide 31 is an arc-shaped strip, comprising two arc-shaped strips arranged vertically; the second arc-shaped guide 33 is an arc-shaped strip, comprising two arc-shaped strips arranged vertically.
[0038] The first arc-shaped guide 31 and the second arc-shaped guide 33 constitute a guide group. Furthermore, the correction component 3 is provided with several guide groups, which are arranged back and forth along the workpiece movement direction.
[0039] In a preferred embodiment, the first mounting bracket 32 has a first insertion hole 321 and a first guide post 322 protruding from it. The first side seat 51 has a first threaded hole 511 and a first guide groove 512. A first screw 61 is fitted into the first threaded hole 511. One end of the first screw 61 is threaded into the first threaded hole 511, and the other end of the first screw 61 is inserted into the first insertion hole 321 and locked with a first nut 513. The first nut 513 is threaded into the first screw 61 and can be secondary sealed with adhesive to prevent loosening during use.
[0040] The first guide post 322 is inserted into the first guide groove 512 to form a sliding fit;
[0041] A first reset spring (not shown in the figure) is assembled between the first mounting bracket 32 and the first side seat 51. When encountering a thicker plate, the first arc-shaped guide 31 and the second arc-shaped guide 33 can be adaptively adjusted. When the relative distance between the two increases due to the thickness of the plate, a reset action can be performed.
[0042] The connection structure and connection relationship between the second arc-shaped guide 33 and the second mounting bracket 34, and between the second mounting bracket 34 and the second side seat 52, are the same as the connection structure and connection relationship between the first arc-shaped guide 31 and the first mounting bracket 32, and between the first mounting bracket 32 and the first side seat 51.
[0043] In this way, the first arc-shaped guide 31 and the second arc-shaped guide 33 can move relative to each other along the width direction of the workpiece movement channel (i.e., the thickness direction of the workpiece), and can thus be adaptively adjusted according to the thickness of the workpiece. In addition, the width of the workpiece movement channel can be adjusted to match the width of the workpiece by the relative position of the first screw 61.
[0044] In a preferred embodiment, the first mounting bracket 32 includes a first plate 326 and a second plate 327. The first plate 326 has a vertical slot 323. A connecting rod 324 (two rods arranged vertically in this embodiment) is connected to a first arc-shaped guide 31 (specifically, an arc-shaped strip). The end of the connecting rod 324 has a protrusion and a threaded section. A second nut (not shown in the figure) is fitted onto the threaded section. The threaded section passes through the vertical slot 323, and the second nut is locked onto the threaded section. The sidewall of the hole in the first plate 326 is confined between the protrusion and the second nut. Similarly, the connection structure and method between the other arc-shaped strip and the first plate 326 are the same and will not be described further here. The two arc-shaped strips are connected to the two ends of the vertical slot 323, forming two action points, which not only facilitates the workpiece alignment operation but also adapts to workpieces of different widths (with the vertical direction as the width direction).
[0045] Furthermore, the second plate 327 has a first horizontal bar hole 325, and a first fastener (not shown in the figure) is fitted into the first horizontal bar hole 325. The first plate 326 has a first locking hole, and the first fastener passes through the first locking hole and the first horizontal bar hole 325 in sequence. The first plate 326 is locked together with the second plate 327 by the first fastener. In this way, the position of the first plate 326 relative to the second plate 327 can be adjusted by adjusting the relative position of the first locking hole with respect to the first horizontal bar hole 325, thereby realizing the distance between several guide groups (arc-shaped guides) to accommodate workpieces of different lengths (with the length direction along the workpiece movement direction as the length direction).
[0046] In this utility model, the connection structure and connection method between each arc-shaped guide component of each guide group and the corresponding mounting bracket, as well as the connection structure and connection method between the corresponding mounting bracket and the corresponding fixed base, are all the same and will not be described in detail here.
[0047] In this embodiment, there are two sets of guiding groups, and two first plates 326 are correspondingly arranged in the two sets of guiding groups. The two first plates 326 share a second plate 327. Specifically, the two first plates 326 located on the same side are locked together with the same second plate 327. The first insertion hole 321 and the first guide post 322 are both provided on the second plate 327.
[0048] Furthermore, the working surface of the first arc-shaped guide 31 is a rough surface for easy clamping, and can be provided with cotton strips, plastic strips, etc.
[0049] In a preferred embodiment, the guide roller group 4 includes at least two sets of guide rollers, each pair including a first guide roller 42 and a second guide roller 43 arranged opposite to each other and positioned back and forth along the workpiece movement direction. A workpiece clamping gap is formed between the first guide roller 42 and the second guide roller 43, which may be slightly larger than the workpiece thickness. Rubber sleeves may be fitted onto the first guide roller 42 and the second guide roller 43.
[0050] Specifically, refer to Figure 1 As shown, the axial ends of the first guide roller 42 are mounted on the third mounting bracket 7, for reference. Figure 2 As shown, the third mounting bracket 7 has a second threaded hole 71 and a second guide post 72 protruding from it. The first side seat 51 has a second insertion hole 514 and a second guide groove 515. The second threaded hole 71 is fitted with a second screw 62, which is inserted into the second insertion hole 514 and threadedly connected to the second threaded hole 71.
[0051] The second guide post 72 is inserted into the second guide groove 515 to form a sliding fit;
[0052] A second return spring (not shown in the figure) is assembled between the second mounting bracket 7 and the first side seat 51.
[0053] The second mounting bracket 7 includes a third plate 73 and a fourth plate 74. The axial ends of the first guide roller 42 are rotatably connected to the third plate 73. The fourth plate 74 has a second horizontal bar hole 741, which is fitted with a second fastener (not shown in the figure). The third plate 73 has a second fastening hole, and the second fastener passes through both the second fastening hole and the second horizontal bar hole 741 in sequence. The third plate 73 is locked together with the fourth plate 74 by the second fastener. Thus, by adjusting the relative position of the second fastening hole with respect to the second horizontal bar hole 741, the position of the third plate 73 relative to the fourth plate 74 can be adjusted, thereby achieving the roller distance between several guide rollers to accommodate workpieces of different lengths.
[0054] The installation structure and installation method of the second guide roller 43 are the same as those of the first guide roller 42, and will not be described again here.
[0055] In a preferred embodiment, the powder spraying unit 1 includes an outer cover 11 and a powder spraying mechanism 12. The powder spraying mechanism 12 includes a first nozzle assembly and a second nozzle assembly. The first nozzle assembly and the second nozzle assembly are arranged opposite to each other, and a powder spraying channel is formed between them. The powder spraying channel and the workpiece clamping gap are located on the same straight line.
[0056] The first nozzle assembly includes a nozzle body 121 and a fourth mounting bracket 122. The fourth mounting bracket 122 has a third horizontal bar hole 123. The third horizontal bar hole 123 is fitted with a third fastener. The nozzle body 121 is locked together with the fourth mounting bracket 122 by the third fastener.
[0057] The fourth mounting bracket 122 has a third insertion hole and a third guide post 124 protruding from it. The side wall of the outer cover 11 has a third guide groove and a third threaded hole. A third screw 63 is fitted into the third threaded hole, passing through it and threadedly connected to it. A third nut is locked at the end of the third screw 63. Preferably, the third nut is threaded to the third screw 63 and can be further sealed with adhesive to prevent loosening during use.
[0058] The third guide post 124 is inserted into the third guide groove to form a sliding fit.
[0059] The nozzle body 121 includes a plurality of nozzles and a nozzle connecting body. In this embodiment, the nozzles are arranged in two rows.
[0060] The third horizontal bar hole 123 allows for adjustment of the lateral spacing between different nozzle assemblies, which can be adjusted according to the length of the workpiece.
[0061] In this invention, the powder spraying unit can also adopt a conventional powder spraying mechanism to achieve the powder spraying operation of the corresponding workpiece.
[0062] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
