In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present invention will be described in detail below with reference to the accompanying drawings. Figures 1 to 12 shown.

[0039] Example 1: See Figure 1A spraying device comprises a frame, the upper end of the frame is connected to an XYZ moving mechanism 10, the lower end of the XYZ moving mechanism 10 is connected to a spray gun assembly 30, and the XYZ moving mechanism 10 can drive the spray gun assembly 30 to move horizontally, vertically and up and down; the frame is connected to at least two sleeve mechanisms 20 for sleeved trousers.

[0040] When the technical solution is implemented, the trousers are first sleeved on the sleeve mechanism 20, and then the XYZ moving mechanism 10 drives the spray gun assembly 30 to move, and each trouser is sprayed with color; when the spraying of one trouser is completed, the XYZ moving mechanism 10 moves the spray gun assembly 30 to the next station to spray another trouser; at the same time, the trousers that have been sprayed with color are replaced manually; as in the present embodiment, the frame is connected with two sleeve mechanisms 20, and two processing stations are correspondingly arranged on the frame. During processing, the trousers, such as jeans, are manually sleeved on the sleeve mechanism 20, and the XYZ moving mechanism 10 drives the spray gun assembly 30 to move to the first station to spray and color the trousers; after the operation is completed, the XYZ moving mechanism 10 drives the spray gun assembly 30 to move to the second station for operation, and the trousers on the first station are replaced manually; after the trousers on the second station are dyed, the XYZ moving mechanism 10 moves the spray gun assembly 30 to the first station, and the trousers on the second station are replaced manually; and this is repeated. There is no need to set up a large conveyor line, and spraying does not require manual operation; it only needs to set the processing program and control the movement of the XYZ moving mechanism 10 and the movement of the spray gun assembly 30 through the control device. The control device can adopt a PLC system, etc. This is the existing technology and will not be repeated.

[0041] See also 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 bottom block 11 arranged laterally, a plurality of transverse guide rails 12 are arranged on the upper end surface of the transverse bottom block 11, each transverse guide rail 12 is slidably connected to a plurality of transverse sliders 17, the transverse sliders 17 are connected to a transverse moving plate 18, and the transverse moving plate 18 is connected to a transverse driving mechanism for driving the transverse moving plate 18 to move laterally.

[0042] Preferably, the upper end surface of the transverse bottom block 11 is provided with a transverse belt 13 arranged laterally, and the two ends of the transverse belt 13 are respectively fixed to the transverse bottom block 11. The transverse driving mechanism includes a transverse motor 14 fixed to a transverse movable plate 18. The transverse motor 14 is drivingly connected to an upper transverse pressure wheel 15. The transverse movable plate 18 is rotatably connected to a lower transverse pressure wheel 16. The transverse belt 13 is wound around the upper transverse pressure wheel 15 and the lower transverse pressure wheel 16.

[0043] The transverse moving mechanism 1 in the XYZ moving mechanism 10 adopts a transverse guide rail 12 and a transverse slider 17 for transverse guidance; then a transverse driving mechanism is adopted to drive the transverse moving plate 18 so that it can move linearly along the transverse guide rail 12 along with the transverse slider 17; the transverse driving mechanism can be a transverse linear module, such as a screw nut structure, or it can directly adopt a combination of a transverse motor 14 and a transverse roller, the transverse motor 14 drives the transverse roller to rotate, and the transverse roller rolls along the transverse bottom block 11, and drives the transverse moving plate 18 to move under the drive of friction. In this embodiment, a combination of a belt and an upper transverse pressure wheel 15 and a lower transverse pressure wheel 16 is used. The transverse motor 14 drives the upper transverse pressure wheel 15 to rotate, and the upper transverse pressure wheel 15 and the lower transverse pressure wheel 16 drive the belt to move relative to each other. Since the belt is fixed to the transverse bottom block 11, the upper transverse pressure block and the lower transverse pressure block move with the transverse moving block; secondly, the use of this structure has a limiting effect. When the transverse moving block moves to the terminal end close to the belt, the friction between the belt and the upper transverse pressure block and the lower transverse pressure block suddenly increases, and the closer to the required friction force, the greater it is, until the driving force of the transverse motor 14 is insufficient to overcome the friction force, so that the transverse moving block cannot continue to approach the terminal end of the belt, thereby achieving a limiting effect.

[0044] See also 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 longitudinal bottom block 21 arranged longitudinally and a longitudinal moving plate 25 arranged vertically, one end of the longitudinal bottom block 21 is fixed to the transverse bottom block 11, a side surface of the longitudinal bottom block 21 is connected to a plurality of longitudinal guide rails 27, each longitudinal guide rail 27 is slidably connected to a plurality of longitudinal sliders 26, the longitudinal moving plate 25 is fixedly connected to all the longitudinal sliders 26, and the longitudinal moving plate 25 is connected to a longitudinal driving mechanism for driving the longitudinal moving plate 25 to move.

[0045] Preferably, the longitudinal driving mechanism includes a longitudinal rack 22 arranged on the longitudinal bottom block 21 , the longitudinal movable plate 25 is connected to a longitudinal motor 24 , the longitudinal motor 24 is driven and connected to a longitudinal gear 23 , and the longitudinal gear 23 is meshed with the longitudinal rack 22 .

[0046] The longitudinal moving mechanism 2 in this embodiment also adopts a combination of a slide rail and a slider to guide the longitudinal moving plate 25 to perform longitudinal linear movement; 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 the 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 are driven to move by friction.

[0047] The longitudinal drive mechanism of this embodiment adopts a gear rack structure. A longitudinal rack 22 is arranged on the longitudinal bottom block 21. The longitudinal motor 24 drives the longitudinal gear 23 to rotate. Since the longitudinal rack 22 is fixed, the longitudinal gear 23 moves longitudinally 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 moving accuracy and slow movement. When driving the spray gun assembly 30 to move longitudinally, it is only necessary to fine-tune its position so that the spray gun assembly 30 is kept at a good distance from the trousers to be sprayed.

[0048] See also Figure 6 , Figure 5 The XYZ moving mechanism 10 includes a lifting mechanism 3 connected to the longitudinal moving plate 25, and 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, and a vertical driving mechanism is provided between the lifting block 31 and the longitudinal moving plate 25, which can drive the vertical moving plate to move up and down.

[0049] In actual application, the lifting block 31 has a relatively large range of up and down movement, and needs to drive the spray gun assembly 30 to move along the length direction of the pants. If the longitudinal moving plate 25 is connected to the vertical guide rail 32, the vertical length of the longitudinal moving plate 25 is relatively large, resulting in a larger overall volume of the longitudinal moving plate 25 and a higher cost. In this embodiment, the vertical guide rail 32 is set on the lifting block 31, so the width of the lifting block 31 can be set relatively small, which is conducive to miniaturization and cost reduction. When moving, the lifting block 31 is driven up and down by the vertical driving mechanism, and the vertical guide rail 32 and the vertical slider 33 slide relative to each other.

[0050] See also Figure 6 The vertical driving mechanism includes a vertical belt 37 arranged on the side of the lifting block 31, the longitudinal moving plate 25 is connected to a vertical motor 36, the vertical motor 36 drives the upper vertical wheel 35, the longitudinal moving plate 25 is connected to the lower vertical wheel 34, and the middle part of the vertical belt 37 is connected to the upper vertical wheel 35 and the lower vertical wheel 34.

[0051] Secondly, the vertical drive mechanism adopts a combination of an upper vertical wheel 35, a lower vertical wheel 34 and a vertical belt 37; the vertical motor 36 drives the upper vertical wheel 35 to rotate, and the upper vertical wheel 35 and the belt move relative to each other. Since the belt is fixed to the lifting block 31, the belt moves the lifting block 31 up and down. The combination of the upper vertical wheel 35 and the lower vertical wheel 34 makes the middle part of the belt S-shaped, and the contact area with the upper vertical wheel 35 and the lower vertical wheel 34 is large to avoid slipping. Secondly, this structure also achieves an automatic limit effect. See also Figure 6 , Figure 7 as well as Figures 10 to 12The spray gun assembly 30 includes a connecting frame 4, the connecting frame 4 is connected to a first rotating mechanism 61, the first rotating mechanism 61 is driven and connected to a first rotating plate 63 and drives the first rotating plate 63 to rotate, the first rotating plate 63 is connected to a second rotating mechanism 65, the second rotating mechanism 65 is driven and connected to a second rotating plate 67 and drives the first rotating plate 63 to rotate, the second rotating plate is connected to a third rotating motor 68, and the third rotating motor 68 is driven and connected to the spray gun 50; the length directions of the output shaft of the first rotating mechanism 61, the output shaft of the second rotating mechanism 65 and the output shaft of the third rotating motor 68 are all perpendicular to each other.

[0052] The connecting frame can be connected to the lifting block 31 of the lifting mechanism 3; in order to make the spray gun 50 more flexible, with posture adjustment, and multi-directional work, this embodiment adopts three rotation dimensions for adjustment. Three rotating motors 51 drive the spray gun 50 to rotate in three different directions. The first rotating mechanism 61, the second rotating mechanism 65 and the third rotating motor 68 can rotate in the vertical direction, the horizontal direction and the longitudinal direction, such as: the output shaft of the first rotating mechanism 61 is vertically arranged, the output shaft of the second rotating mechanism 65 is horizontally arranged, and the output shaft of the third rotating motor 68 is longitudinally arranged; the first rotating mechanism 61 can drive the spray gun 50 to rotate in the horizontal plane, the second rotating mechanism 65 can drive the spray gun 50 to rotate in the vertical plane perpendicular to the horizontal direction, and the third rotating motor 68 can drive the spray gun 50 to rotate in the vertical plane perpendicular to the longitudinal direction. It can be understood that: the rotation direction of the first rotating mechanism 61, the second rotating mechanism 65, and the third rotating motor 68 can be arbitrary and not limited; it only needs that the output shafts of the three rotating motors 51 are perpendicular to each other.

[0053] Further, the first rotating mechanism 61 includes a first rotating motor 612 , the second rotating mechanism 65 includes a second rotating motor 652 , and the second rotating mechanism 65 includes a second rotating motor 652 .

The second rotating mechanism 65 also includes a second reducer 651, the second rotary motor 652 is connected to the second reducer 651, and the output shaft of the second reducer 651 is connected to the second rotating plate through the second rotating seat 66.

[0056] Secondly, see Fig.13 The third rotating motor 68 is connected to the spray gun 50 and controls the spray gun 50 spray speed, when the control is performed, see Fig.13 The rotating shaft of the third rotating motor 68 is connected to a cam 81 or a deflection wheel, and the cam 81 or the deflection wheel is connected to a control valve stem 84, and the control valve stem 84 is inserted into the liquid flow channel of the spray gun; by controlling the depth of the control valve stem 84 inserted into the liquid flow channel 83, the flow rate of the liquid is controlled, thereby controlling the injection speed and the injection amount per unit time; secondly, the control valve stem is connected to an elastic member 83 to facilitate its reset.

[0057] In order to facilitate the fixed connection of the first rotating mechanism 61, the second rotating mechanism 65, and the third rotating motor 68, in this embodiment, the first rotating plate 63 and the second rotating plate 67 are respectively set to be L-shaped. Secondly, in order to facilitate the wiring, the first vertical section 632 and the second vertical section 671 can be set to a hollow structure. In the specific setting, the first horizontal section 631 is fixedly connected to the first rotating seat 62, and the second vertical section 671 is connected to the second rotating seat 66. Both sides of the first rotating plate 63 and the second rotating plate 67 are connected with reinforcement sheets 64 to improve the structural strength.

[0058] Preferably, the second horizontal section 672 is also connected to a sensor 69 for sensing whether an operating handle 60 is present, so as to facilitate adjustment of the position of the spray gun 50 .

[0059] See also Figure 7 , Figure 8The sleeve mechanism 20 includes: a box body, the upper end of the box body is connected to a rotating mechanism for driving the box body to rotate; the box body is provided with an upper top plate 513 and a lower bottom plate 518, a side plate 53 is connected between the upper top plate 513 and the lower bottom plate 518, the upper top plate 513 has a telescopic cylinder 510 through two connecting seats 514, the piston of the telescopic cylinder 510 is hinged with 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 is provided with a movable groove 520 for the support rod 517 to pass through, the lower end of the support rod 517 extends out of the box body, the support rod 517 is hollow, the lower end of the support rod 517 is sealed, the middle part of the support rod 517 is provided with a sleeve connection portion and an elastic capsule 512 is sleeved, the sleeve connection portion is provided with a plurality of air holes 521, and the upper end of the support rod 517 is connected with an air intake valve 511.

[0060] In this embodiment, the box body can protect the upper end of the support rod 517 and the telescopic cylinder 510 to prevent external interference. At the same time, the upper top plate 513 can be connected to the frame to support the support rod 517, etc. When in use, the air inlet valve 511 is connected to the air source or the inflation device through the air pipe, such as a high-pressure gas cylinder, an air compressor, an air pump, etc.; after inflation, the capsule 512 sleeved on the outside of the support rod 517 bulges, and the two bulging capsules 512 abut against each other to simulate the lower body of the human body. At this time, the pants are sleeved on the outside of the two capsules 512; when the pants are sprayed and colored, it is necessary to color the two sides of the pants separately. In order to facilitate the operation of the spray gun 50, it is necessary to straighten the two sides of the pants separately, that is, in a vertical state, so the pants need to be tilted, and the two support rods 517 need to swing slightly. When controlling the swing of the support rod 517, this embodiment adopts the combination of the telescopic cylinder 510 and the box body. 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 and the weight of the capsule 512 and the pants, the other end of the connecting block 57 bears a greater force, so the other end of the connecting block 57 abuts against the lower bottom plate 518. At the same time, the connecting block 57 and the support rod 517 are fixedly connected, and the angle between the support rod 517 and the connecting block 57 is fixed, generally 90 degrees. At this time, if the left side of the pants needs to be colored, 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 bottom plate 518, the left connecting block 57 rotates and drives the left supporting rod 517 to swing. At the same time, the supporting rod 517 moves in the movable groove 520 until the left supporting rod 517 is straightened and in a vertical state. At the same time, in order to maintain the angle between the two support rods 517, the piston of the right telescopic cylinder 510 pulls the right connecting block 57 upward, and 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 inclination angle of the support rod 517 increases and moves along the corresponding movable groove 520.

[0061] Furthermore, the upper end of the support rod 517 is also connected to an exhaust valve 58 and an air pressure sensor 59 .

[0062] By providing 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 a first threshold value, the exhaust valve 58 opens; when the air pressure is lower than a second threshold value, the exhaust valve 58 closes, so that the air pressure inside the capsule 512 is maintained within a reasonable range, which allows the capsule to inflate while avoiding the risk of exploding.

[0063] Furthermore, the connecting seat 514 is hinged to the telescopic cylinder 510, one end of the connecting block 57 is connected to a rotating shaft 55, and the box body is also provided with a rear baffle, and the rotating shaft 55 is rotatably connected to the rear baffle.

[0064] 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 from abutting against the end of the movable groove 520 and bearing gravity, which will 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, and 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 with the connecting seat 514 so that the telescopic cylinder 510 can swing.

[0065] In the specific setting, two lugs 515 are provided at the upper end of the telescopic cylinder 510, and the lower end of the connecting seat 514 extends between the two lugs 515. Both the lug 515 and the connecting seat 514 are provided with axial holes, and the lug 515 is rotatably connected to the connecting seat 514 through a shaft rod.

[0066] Furthermore, the lower end of the piston is connected to an extension block 516, the lower end of the extension block 516 is in an 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, and 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.

[0067] In order to facilitate the hinge connection between the piston and the connecting block 57, the lower end of the piston is connected with an extension block 516, which is connected to the piston by a threaded connection, and the position of the extension block 516 can be adjusted by the threaded connection. Secondly, the extension block 516 and the connecting block 57 are rotatably connected by a connecting shaft, and the connecting block 57 can rotate relative to the extension block 516.

[0068] Furthermore, the connecting block 57 clamps and connects the upper end of the support rod 517 through the clamping block 56. This connection method can achieve both clamping and position adjustment. To facilitate the connection of the capsule 512, the middle and upper part of the support rod 517 is sleeved with a sleeve 519, and the middle part of the sleeve 519 is provided with a sleeve, which is sleeved with the support rod 517 and connected to the upper end of the capsule 512, so as to facilitate the connection of the upper end of the capsule 512.

[0069] Furthermore, the rotating mechanism includes a rotating motor 51 and a rotating reducer, and the rotating motor 51 is connected to the upper top plate 513 of the box body through the rotating reducer.

[0070] The rotating mechanism is fixed to the frame through the fixing plate 52, the rotating motor 51 is connected to the rotating reducer, and the rotating reducer is connected to the fixing plate 52; at the same time, the rotating reducer is connected to the upper top plate 513 of the box body and drives it to rotate.

[0071] See also Figure 1 , Figure 6 , Figure 7 as well as Fig.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 member is connected between the adjusting block 43 and the lifting block 31; the box body is connected to a ring body 522.

[0072] This embodiment is mainly for automatic spraying. When manual operation is required, this embodiment is provided with an operating handle 60 and a manual lifting mechanism 3. When the XYZ moving mechanism 10 moves the spray gun 50 close to the trousers, the operator can hold the operating handle 60 and then perform up and down operations, or can operate the annular body 522 to rotate the capsule 512, etc. with one hand. It can be understood that the XYZ moving mechanism 10 cannot be manually operated, and manual operation can only be performed up and down. During the up and down operation, the elastic member is changed, and the up and down movement of the adjustment block 43 is adjusted by the elastic member, thereby adjusting the up and down movement of the spray gun 50. The elastic member can be a spring, etc.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
