[0037] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 12 As shown.

[0042] Example 1: See Figure 1 A spraying device includes a frame, an XYZ moving mechanism 10 connected to the upper end of the frame, a spray gun assembly 30 connected to the lower end of the XYZ moving mechanism 10, the XYZ moving mechanism 10 being able to drive the spray gun assembly 30 to move laterally, longitudinally, and vertically; the frame is connected to at least two fitting mechanisms 20 for fitting trousers.

[0043] In this technical solution, the pants are first fitted onto the fitting mechanism 20, and then the XYZ moving mechanism 10 drives the spray gun assembly 30 to move and spray each pair of pants with color. After one pair of pants is finished being sprayed, the XYZ moving mechanism 10 moves the spray gun assembly 30 to the next workstation to spray another pair of pants. At the same time, the manually replaced pants after they have been sprayed. In this embodiment, the frame is connected to two fitting mechanisms 20, and two processing workstations are set on the frame. During processing, the pants, such as jeans, are fitted onto the fitting mechanism 20 by hand, and the XYZ moving mechanism 10 drives the spray gun assembly 30 to move to the first workstation to spray and color the pants. After the operation is completed, the XYZ moving mechanism 10 drives the spray gun assembly 30 to move to the second workstation, and the manually replaced the pants at the first workstation. After the pants at the second workstation are finished being dyed, the XYZ moving mechanism 10 moves the spray gun assembly 30 back to the first workstation, and the manually replaced the pants at the second workstation again. This process is repeated. There is no need to set up a large conveyor line, and spraying requires no manual operation; only a processing program needs to be set, and the movement of the XYZ moving mechanism 10 and the spray gun assembly 30 can be controlled by a control device. The control device can be a PLC system, etc. This is existing technology and will not be described in detail.

[0044] See Figures 2 to 5 The XYZ moving mechanism 10 includes a transverse moving mechanism 1 connected to the frame. The transverse moving mechanism 1 includes a transverse base block 11 arranged transversely. The upper surface of the transverse base block 11 is provided with several transverse guide rails 12. Each transverse guide rail 12 is slidably connected to several transverse sliders 17. The transverse sliders 17 are connected to a transverse moving plate 18. The transverse moving plate 18 is connected to a transverse driving mechanism for driving the transverse moving plate 18 to move laterally.

[0045] Preferably, the upper end surface of the horizontal base block 11 is provided with a horizontally arranged horizontal belt 13, and the two ends of the horizontal belt 13 are respectively fixed to the horizontal base block 11. The horizontal driving mechanism includes a horizontal motor 14 fixed to the horizontal moving plate 18. The horizontal motor 14 drives and connects to the horizontal upper pressure roller 15. The horizontal moving plate 18 is rotatably connected to the horizontal lower pressure roller 16. The horizontal belt 13 is wound around the horizontal upper pressure roller 15 and the horizontal lower pressure roller 16.

[0046] The lateral movement mechanism 1 in the XYZ movement mechanism 10 uses a lateral guide rail 12 and a lateral slider 17 for lateral guidance; then a lateral drive mechanism is used to drive the lateral movement plate 18 so that it can move linearly along the lateral guide rail 12 along with the lateral slider 17; the lateral drive mechanism can be a lateral linear module, such as a lead screw and nut structure, or it can directly use a combination of a lateral motor 14 and a lateral roller. The lateral motor 14 drives the lateral roller to rotate, and the lateral roller rolls along the lateral base block 11. Under the drive of friction, the lateral movement plate 18 is driven to move. In this embodiment, a combination of a belt and a transverse upper pressure roller 15 and a transverse lower pressure roller 16 is used. The transverse motor 14 drives the transverse upper pressure roller 15 to rotate, and the transverse upper pressure roller 15 and the transverse lower pressure roller 16 drive the belt to move relative to each other. Since the belt is fixed to the transverse bottom block 11, the transverse upper pressure block and the transverse lower pressure block move with the transverse moving block. Secondly, this structure has a limiting effect. When the transverse moving block moves close to the end of the belt, the friction between the belt and the transverse upper pressure block and the transverse lower pressure block suddenly increases, and the friction increases as it gets closer, until the driving force of the transverse motor 14 is insufficient to overcome the friction, so that the transverse moving block cannot continue to approach the end of the belt, thus achieving a limiting effect.

[0047] See Figures 3 to 5 The XYZ moving mechanism 10 includes a longitudinal moving mechanism 2 connected to the transverse moving plate 18. The longitudinal moving mechanism 2 includes a longitudinally arranged longitudinal base block 21 and a vertically arranged longitudinal moving plate 25. One end of the longitudinal base block 21 is fixed to the transverse base block 11. A plurality of longitudinal guide rails 27 are connected to one side of the longitudinal base block 21. A plurality of longitudinal sliders 26 are slidably connected to each longitudinal guide rail 27. The longitudinal moving plate 25 is fixedly connected to all the longitudinal sliders 26. The longitudinal moving plate 25 is connected to a longitudinal driving mechanism for driving the longitudinal moving plate 25 to move.

[0048] Preferably, the longitudinal drive mechanism includes a longitudinal rack 22 disposed on the longitudinal base block 21, a longitudinal moving plate 25 connected to a longitudinal motor 24, and a longitudinal gear 23 driven by the longitudinal motor 24, which meshes with the longitudinal rack 22.

[0049] In this embodiment, the longitudinal moving mechanism 2 also adopts a combination of slide rail and slider to guide the longitudinal moving plate 25 to move longitudinally linearly; the longitudinal moving plate 25 moves under the drive of the longitudinal driving mechanism; the longitudinal driving mechanism can adopt existing technology, such as using a longitudinal motor 24 to drive a longitudinal roller, the longitudinal roller moves along the surface of the longitudinal bottom block 21, and the longitudinal motor 24 and the longitudinal moving block move by friction.

[0050] In this embodiment, the longitudinal drive mechanism adopts a rack and pinion structure. A longitudinal rack 22 is set on the longitudinal base block 21, and the longitudinal motor 24 drives the longitudinal gear 23 to rotate. Since the longitudinal rack 22 is fixed, the longitudinal gear 23 moves longitudinally along with the longitudinal motor 24 and the longitudinal moving plate 25. The transverse drive mechanism can also adopt this structure. This structure has the characteristics of high movement accuracy and slow movement. When driving the spray gun assembly 30 to move longitudinally, only its position needs to be finely adjusted so that the spray gun assembly 30 is kept at a good distance from the pants to be sprayed.

[0051] See Figure 6 , Figure 5 The XYZ moving mechanism 10 includes a lifting mechanism 3 connected to the longitudinal moving plate 25. The lifting mechanism 3 includes a vertically arranged lifting block 31. The lifting block 31 is connected to a vertical guide rail 32. The vertical guide rail 32 is slidably connected to a vertical slider 33. The vertical slider 33 is connected to the transverse moving plate 18. A vertical driving mechanism is provided between the lifting block 31 and the longitudinal moving plate 25 to drive the vertical moving plate to move up and down.

[0052] In practical applications, the lifting block 31 moves up and down over a relatively large range, requiring the spray gun assembly 30 to move along the length of the pants. If a longitudinal moving plate 25 is used to connect to the vertical guide rail 32, the vertical length of the longitudinal moving plate 25 is large, resulting in a large overall volume and high cost. In this embodiment, a vertical guide rail 32 is set on the lifting block 31, which allows the width of the lifting block 31 to be relatively small, which is beneficial for miniaturization and cost reduction. During movement, the lifting block 31 is driven to move up and down by a vertical drive mechanism, and the vertical guide rail 32 slides relative to the vertical slider 33.

[0053] See Figure 6 The vertical drive mechanism includes a vertical belt 37 disposed on the side of the lifting block 31, a vertical motor 36 connected to the longitudinal moving plate 25, the vertical motor 36 driving the upper vertical wheel 35, the longitudinal moving plate 25 being connected to the lower vertical wheel 34, and the middle part of the vertical belt 37 being wound around the upper vertical wheel 35 and the lower vertical wheel 34.

[0054] Secondly, the vertical drive mechanism employs a combination of an upper vertical wheel 35, a lower vertical wheel 34, and a vertical belt 37. A vertical motor 36 drives the upper vertical wheel 35 to rotate, causing relative movement between the upper vertical wheel 35 and the belt. Since the belt is fixed to the lifting block 31, the belt carries the lifting block 31 up and down. The combination of the upper vertical wheel 35 and the lower vertical wheel 34 results in an S-shaped section in the middle of the belt, maximizing the contact area with both the upper and lower vertical wheels and preventing slippage. Furthermore, this structure also achieves an automatic limit function.

[0055] See Figure 6 , Figure 7 as well as Figures 10 to 12 The spray gun assembly 30 includes a connecting frame 4, which is connected to a first rotating mechanism 61. The first rotating mechanism 61 drives a first rotating plate 63 to rotate. The first rotating plate 63 is connected to a second rotating mechanism 65, which drives a second rotating plate 67 to rotate. The second rotating plate is connected to a third rotating motor 68, which drives a spray gun 50. The length directions of the output shafts of the first rotating mechanism 61, the second rotating mechanism 65, and the third rotating motor 68 are all perpendicular to each other.

[0056] The connecting frame can be connected to the lifting block 31 of the lifting mechanism 3. To enable the spray gun 50 to have greater flexibility, posture adjustment, and multi-directional operation, this embodiment uses three rotational dimensions for adjustment. Three rotary motors 51 drive the spray gun 50 to rotate in three different directions. The first rotary mechanism 61, the second rotary mechanism 65, and the third rotary motor 68 can rotate vertically, horizontally, and longitudinally. For example, the output shaft of the first rotary mechanism 61 is vertically set, the output shaft of the second rotary mechanism 65 is horizontally set, and the output shaft of the third rotary motor 68 is longitudinally set. The first rotary mechanism 61 can drive the spray gun 50 to rotate in the horizontal plane, the second rotary mechanism 65 can drive the spray gun 50 to rotate in a vertical plane perpendicular to the horizontal plane, and the third rotary motor 68 can drive the spray gun 50 to rotate in a vertical plane perpendicular to the longitudinal plane. It can be understood that the rotation direction of the first rotary mechanism 61, the second rotary mechanism 65, and the third rotary motor 68 can be arbitrary and not limited; it is only necessary that the output shafts of the three rotary motors 51 are perpendicular to each other.

[0057] Furthermore, the first rotating mechanism 61 includes a first rotating motor 612, and the second rotating mechanism 65 includes a second rotating motor 652.

[0058] The output shaft of the first rotary motor 612 is connected to the first rotating plate 63, and the output shaft of the second rotary motor 652 is connected to the second rotating plate 67. In this embodiment, to control the rotation speed, the first rotating mechanism 61 further includes a first reducer 611, with the first rotary motor 612 connected to the first reducer 611, and the output shaft of the first reducer 611 connected to the first rotating plate via a first rotating base 62. The second rotating mechanism 65 further includes a second reducer 651, with the second rotary motor 652 connected to the second reducer 651, and the output shaft of the second reducer 651 connected to the second rotating plate via a second rotating base 66. A third rotary motor 68 is connected to the second rotating plate, and the third rotary motor 68 is connected to the spray gun 50 and controls the spray speed of the spray gun 50.

[0059] See Figures 10 to 12The first rotating plate includes a first horizontal section 631 and a first vertical section 632 fixedly connected. The first horizontal section 631 is connected to a first rotating mechanism 61, which drives the first horizontal section 631 to rotate. The first vertical section 632 is fixedly connected to a second rotating mechanism 65. The second rotating plate includes a second horizontal section 672 and a second vertical section 671 fixedly connected. The second vertical section 671 is driven by a second rotating mechanism 65, which drives the second vertical section 671 to rotate. The second horizontal section 672 is fixedly connected to a third rotating motor 68.

[0060] Secondly, see Figure 13 The third rotary motor 68 is connected to the spray gun 50 and controls the spray speed of the spray gun 50. When controlling it, refer to... Figure 13 The shaft of the third rotary motor 68 is connected to a cam 81 or a deflector wheel. The cam 81 or deflector wheel is connected to a control valve stem 84, which is inserted into the liquid flow channel of the spray gun. The flow rate of the liquid is controlled by the depth of the control valve stem 84 inserted into the liquid flow channel 83, thereby controlling the spray speed and the spray volume per unit time. Secondly, the control valve stem is connected to an elastic element 83 to facilitate its reset.

[0061] To facilitate the fixed connection of the first rotating mechanism 61, the second rotating mechanism 65, and the third rotating motor 68, the first rotating plate 63 and the second rotating plate 67 are respectively set as L-shaped in this embodiment. Secondly, for ease of wiring, the first vertical section 632 and the second vertical section 671 can both be set as hollow structures. In a specific configuration, the first horizontal section 631 is fixedly connected to the first rotating base 62, and the second vertical section 671 is connected to the second rotating base 66. Reinforcing plates 64 are connected to both sides of the first rotating plate 63 and the second rotating plate 67 to improve structural strength.

[0062] Preferably, the second horizontal segment 672 is also connected to a sensor 69 for sensing whether there is an operating handle 60, so as to facilitate adjusting the position of the spray gun 50.

[0063] See Figure 7 , Figure 8The connecting mechanism 20 includes: a housing, with a rotating mechanism connected to the upper end of the housing for driving the housing to rotate; the housing has an upper top plate 513 and a lower bottom plate 518, with a side plate 53 connected between the upper top plate 513 and the lower bottom plate 518; the upper top plate 513 has telescopic cylinders 510 via two connecting seats 514; the piston of the telescopic cylinder 510 is hinged to a connecting block 57; one end of the connecting block 57 is connected to a support rod 517; the two support rods 517 are located between the two telescopic cylinders 510; the lower bottom plate 518 has a movable groove 520 for the support rod 517 to pass through; the lower end of the support rod 517 extends out of the housing; the support rod 517 is hollow; the lower end of the support rod 517 is sealed; the middle part of the support rod 517 has a connecting part and a flexible capsule 512 is fitted thereon; the connecting part has multiple air holes 521; and the upper end of the support rod 517 is connected to an air inlet valve 511.

[0064] In this embodiment, the housing protects the upper end of the support rod 517 and the telescopic cylinder 510 from external interference. Simultaneously, the top plate 513 can be connected to the frame to support the support rod 517, etc. During use, the air inlet valve 511 connects to an air source or inflation device, such as a high-pressure gas cylinder, air compressor, or air pump, via an air pipe. After inflation, the capsule 512, fitted onto the outside of the support rod 517, inflates. The two inflated capsules 512 abut against each other to simulate the lower body of a human body. At this time, trousers are placed over the two capsules 512. When spraying color onto the trousers, both sides need to be colored separately. To facilitate the operation of the spray gun 50, both sides of the trousers need to be straightened, i.e., in a vertical position. Therefore, the trousers need to be tilted, and the two support rods 517 need to swing slightly. In controlling the swing of the support rod 517, this embodiment uses a combination of the telescopic cylinder 510 and the housing. Since one end of the connecting block 57 is hinged to the piston, the connecting block 57 can rotate relative to the piston. Due to the weight of the support rod 517 itself, as well as the weight of the capsule 512 and the pants, the other end of the connecting block 57 bears a large force. Therefore, the other end of the connecting block 57 abuts against the lower base plate 518. At the same time, the connecting block 57 and the support rod 517 are fixedly connected, and the included angle between the support rod 517 and the connecting block 57 is fixed, generally 90 degrees. At this time, if it is necessary to color the left side of the pants, the piston of the left telescopic cylinder 510 can push the left connecting block 57 downward. Since the right end of the left connecting block 57 abuts against the lower base plate 518, the left connecting block 57 rotates, causing the left support rod 517 to swing. At the same time, the support rod 517 moves in the movable groove 520 until the left support rod 517 is straight and in a vertical state. Meanwhile, in order to maintain the included angle of the two support rods 517, the piston of the right telescopic cylinder 510 pulls the right connecting block 57 upward. The left end of the right connecting block 57 abuts against the lower base plate 518, the right connecting block 57 rotates, and drives the right support rod 517 to swing. The tilt angle of the support rod 517 increases and it moves along the corresponding movable groove 520.

[0065] Furthermore, the upper end of the support rod 517 is also connected to an exhaust valve 58 and a pressure sensor 59.

[0066] By setting an exhaust valve 58 and an air pressure sensor 59, the air pressure inside the capsule 512 can be controlled. When the internal air pressure is higher than the first threshold, the exhaust valve 58 opens; when the air pressure is lower than the second threshold, the exhaust valve 58 closes, so that the air pressure inside the capsule 512 is kept within a reasonable range, which can inflate while avoiding the risk of bursting.

[0067] Furthermore, the connecting seat 514 is hinged to the telescopic cylinder 510, one end of the connecting block 57 is connected to the rotating shaft 55, and the box body is also provided with a rear baffle, with the rotating shaft 55 rotatably connected to the rear baffle.

[0068] When driving the connecting block 57 to rotate, the length of the movable groove 520 needs to be set relatively large to avoid the support rod 517 abutting against the end of the movable groove 520 and bearing gravity, which would affect the state of the support rod 517. To avoid this situation, in this embodiment, a rotating shaft 55 is set on the connecting block 57. The rotating shaft 55 can be rotatably connected to the rear baffle through a bearing. When the telescopic cylinder 510 drives the connecting block 57 to move downward, the connecting block 57 rotates around the rotating shaft 55, and drives the support rod 517 to rotate. Since one end of the connecting block 57 is restricted, the end of the connecting block 57 connected to the piston moves in an arc shape when moving; the telescopic cylinder 510 needs to adjust its posture, so the telescopic cylinder 510 is hinged to the connecting seat 514 so that the telescopic cylinder 510 can swing.

[0069] In a specific configuration, the upper end of the telescopic cylinder 510 is provided with two lugs 515, and the lower end of the connecting seat 514 extends between the two lugs 515. Both the lugs 515 and the connecting seat 514 are provided with shaft holes, and the lugs 515 are rotatably connected to the connecting seat 514 through a shaft.

[0070] Furthermore, the lower end of the piston is connected to an extension block 516, the lower end of the extension block 516 is inverted U-shape, the upper end of the extension block 516 is provided with a threaded hole, the lower end of the piston is provided with an external thread, the extension block 516 is threadedly connected to the piston, the other end of the connecting block 57 extends into the interior of the extension block, and the extension block is rotatably connected to the connecting block 57 through a connecting shaft.

[0071] To facilitate the hinge connection between the piston and the connecting block 57, an extension block 516 is connected to the lower end of the piston. The extension block 516 is connected to the piston via a threaded connection, which allows for adjustment of the position of the extension block 516. Furthermore, the extension block 516 and the connecting block 57 are rotatably connected via a connecting shaft, allowing the connecting block 57 to rotate relative to the extension block 516.

[0072] Furthermore, the connecting block 57 clamps and connects the upper end of the support rod 517 via the clamping block 56. This connection method can achieve both clamping and position adjustment. To facilitate the connection of the capsule 512, a sleeve 519 is fitted onto the upper middle part of the support rod 517. The sleeve 519 has a tube in the middle, which is fitted onto the support rod 517 and connected to the upper end of the capsule 512 to facilitate the connection of the upper end of the capsule 512.

[0073] Furthermore, the rotating mechanism includes a rotary motor 51 and a rotary reducer, with the rotary motor 51 connected to the upper top plate 513 of the housing via the rotary reducer.

[0074] The rotating mechanism is fixed to the frame by a fixed plate 52. The rotating motor 51 is connected to the rotating reducer, and the rotating reducer is connected to the fixed plate 52. At the same time, the rotating reducer is connected to the top plate 513 of the housing and drives it to rotate.

[0075] See Figure 1 , Figure 6 , Figure 7 as well as Figure 10 The second horizontal section 672 is connected to an operating handle 60; the connecting frame includes an adjusting block 43, the adjusting block 43 is connected to a vertical auxiliary guide rail 42, the auxiliary guide rail 42 is slidably connected to an auxiliary slider 41, and the auxiliary slider 41 is fixed to the lifting block 31; an elastic element is connected between the adjusting block 43 and the lifting block 31; the box is connected to an annular body 522.

[0076] This embodiment primarily focuses on automatic spraying. When manual operation is required, this embodiment includes an operating handle 60 and a manual lifting mechanism 3. When the XYZ moving mechanism 10 moves the spray gun 50 closer to the user, the operator can hold the operating handle 60 and perform up-and-down operations, or operate the annular body 522 and rotating capsule 512 with one hand. It is understood that the XYZ moving mechanism 10 cannot be manually operated; manual operation is limited to up-and-down movements. During these movements, the elastic element changes, adjusting the up-and-down movement of the adjusting block 43, thereby adjusting the up-and-down movement of the spray gun 50. The elastic element can be a spring, etc.

[0077] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
