Description

Technical Field

[0001] The present invention relates to the field of button production, and particularly to a button spraying fixture. Background Art

[0002] With the development of society and the gradual improvement of people's living standards, people have a higher pursuit of material culture, and the demand for the beauty and comfort of clothes is also gradually increasing. Most of the clothes people often wear have various button decorations. The richness of button colors provides different aesthetics for clothing. Spraying buttons can meet people's demand for button colors.

[0003] Currently, in the process of button spraying production, if it is necessary to spray both the side and the front of the button, generally, it is padded on the original fixture to make one side of the button protrude, so that the spraying machine can spray ink on the front and side of the button.

[0004] However, the operation of padding on the original fixture to spray the front and side of the button cannot accurately adjust the spraying angle on the one hand, which will result in low spraying accuracy. On the other hand, if different angles need to be adjusted for spraying, it is necessary to re-pad each time, resulting in low spraying efficiency. Summary of the Invention

[0005] Based on this, in view of the problems of low button spraying efficiency and low accuracy, it is necessary to provide a button spraying fixture.

[0006] A button spraying fixture, which is used in cooperation with a spraying machine, includes a rack, at least one rotating gear, a button placing strip, a bottom plate, and a first side plate connected to the bottom plate, wherein:

[0007] The first side plate is provided with at least one first through hole, and the first through hole opens on the side surface of the first side plate;

[0008] The button placing strip is provided with a plurality of accommodating holes for placing buttons;

[0009] The rotating gear passes through the first through hole and is rotatably connected to the first side plate, and the part passing through the first through hole is connected to one end of the button placing strip;

[0010] The rack is arranged on the bottom plate, on the side of the rotating gear away from the button placing strip and meshes with the rotating gear for driving the rotating gear to rotate.

[0011] The above button spraying fixture is connected to the button placing strip through a rotating gear. By pulling the rack that meshes with the rotating gear, the rotating gear can be made to rotate in the direction opposite to the pulling direction of the rack, thereby driving the button placing strip connected to the rotating gear to rotate. This simply and conveniently realizes the angle adjustment of the button placing strip, so that different sides and the front of the buttons on the button placing strip can all be rotated to face the spraying machine directly, facilitating the spraying machine to conveniently spray ink onto the front and sides of the buttons to complete the simultaneous spraying of the front and sides of the buttons. Compared with the previous operation of padding on the original fixture to spray the front and sides of the buttons, pulling the rack can achieve the rotation of the button placing strip at different angles. Thus, when spraying buttons at different angles, there is no need to adjust the height of the fixture each time, improving the spraying efficiency. In addition, when padding the fixture, it is impossible to accurately ensure that the thickness of the padding is exactly the spraying angle required by the button. However, pulling the rack to drive the rotation of the rotating gear can make the button placing strip rotate at any angle to achieve the spraying of buttons at different angles, and corresponding parts of the buttons can be sprayed according to actual needs, improving the spraying accuracy.

[0012] In one embodiment, the rotating gear includes a first runner and a gear sleeved on the first runner. The gear meshes with the rack, and one end of the first runner passes through the first through hole and is rotatably connected to the first side plate.

[0013] In one embodiment, it further includes a second side plate connected to the bottom plate, where:

[0014] The second side plate is spaced from the first side plate and is located on the side of the first side plate away from the button placing strip, and is provided with at least one fourth through hole, and the fourth through hole opens on the side surface of the second side plate;

[0015] The end of the first runner away from the button placing strip passes through the fourth through hole and is rotatably connected to the second side plate.

[0016] In one embodiment, the second side plate is disposed opposite to the first side plate and forms a receiving space for placing the rack with the first side plate, and the fourth through hole is disposed opposite to the first through hole.

[0017] In one embodiment, the pulling direction of the rack is the first direction, the number of the first through holes is multiple, the number of the first through holes is equal to the number of the rotating gear and the fourth through holes, and the multiple first through holes are spaced along the first direction and are in one-to-one correspondence with the fourth through holes.

[0018] In one embodiment, it also includes a positioning pin and a first positioning hole. When the rack drives the gear to rotate to the level of the button bar, the first positioning hole penetrates the second side plate and at least part of the rack. The positioning pin passes through the first positioning hole to connect the second side plate and the rack as a whole.

[0019] In one embodiment, at least one positioning hole group is further included, wherein the positioning hole group includes a second positioning hole and a third positioning hole, wherein:

[0020] The second positioning hole is arranged on a side of the rack close to the second side plate and is spaced apart from the first positioning hole;

[0021] The third positioning hole opens on the surface of the second side plate facing the rack and penetrates through the thickness of the second side plate, and is spaced apart from the first positioning hole;

[0022] The second positioning hole is located at an end of the third positioning hole away from the first direction;

[0023] The distance between the axis of the second positioning hole and the axis of the third positioning hole along the first direction is a set distance;

[0024] When the rack moves the set distance along the first direction, the button bar rotates from a horizontal state to a set angle.

[0025] In one embodiment, there are multiple positioning hole groups, each positioning hole group corresponds to one setting angle, wherein:

[0026] The plurality of positioning hole groups are arranged at intervals along the first direction, and the corresponding setting angles along the first direction gradually increase;

[0027] The difference between the two set distances corresponding to any two of the positioning groups is the distance that the rack moves along the first direction corresponding to the button bar rotating from the first angle to the second angle. The first angle is the set angle corresponding to any two of the positioning groups away from the first direction, and the second angle is the set angle corresponding to the other one.

[0028] In one embodiment, it further includes a second rotating wheel and a third side plate connected to the bottom plate, wherein:

[0029] The third side plate is spaced apart from the first side plate, is located on a side of the first side plate away from the rack, and is provided with at least one fifth through hole, the fifth through hole opening on a side surface of the third side plate;

[0030] The second runner passes through the fifth through-hole and is rotatably connected to the third side plate, and is connected to the other end of the button releasing strip on the side close to the first side plate.

[0031] In one embodiment, the third side plate is disposed opposite to the first side plate, and the fifth through-hole is disposed opposite to the first through-hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The technical solutions provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0058] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, an embodiment of the present invention provides a button painting fixture 10, which is applied to the technical field of button painting and is used in cooperation with a painting machine. The button painting fixture 10 includes a rack 100, at least one rotating gear 200, a button placing bar 300, a bottom plate 500, and a first side plate 400 connected to the bottom plate 500. Specifically, the button painting fixture 10 includes a first fixed through hole 510, and the first fixed through hole 510 penetrates through the bottom plate 500 and the first side plate 400. A fastener passes through the first fixed through hole 510 to connect the bottom plate 500 and the first side plate 400 into a whole. The fastener can be a bolt. The number of rotating gears 200 can be 2, 4, 5, 7, 9 or more, and among them:

[0059] The first side plate 400 is provided with at least one first through hole 410, and the first through hole 410 opens on the side surface of the first side plate 400. When specifically arranged, the first side plate 400 can be a cuboid, and generally the number of the first through holes 410 is set to be equal to the number of the rotating gears 200;

[0060] The button placing strip 300 is provided with a plurality of accommodating holes 310 for placing buttons. When specifically arranged, the button placing strip 300 is generally of a cuboid structure, and the plurality of accommodating holes 310 are arranged at intervals along the length direction of the button placing strip 300. The number of the accommodating holes 310 can be 4, 8, 12, 15, 18 or more. A protrusion 3111 adapted to the buttonhole of the button is arranged in the accommodating hole 310 so that the button is fixed in the accommodating hole 310;

[0061] The rotating gear 200 passes through the first through hole 410 and is rotatably connected to the first side plate 400, and the part of the rotating gear 200 passing through the first through hole 410 is connected to one end of the button placing strip 300. When specifically arranged, the rotating gear 200 and the first through hole 410 can be in an interference fit;

[0062] The rack 100 is arranged on the bottom plate 500, located on the side of the rotating gear 200 away from the button placing strip 300 and meshing with the rotating gear 200, and is used to drive the rotating gear 220 to rotate. When specifically used, the rack 100 is placed on the bottom plate 500, and one end of the rack 100 is pulled so that the rotating gear 200 meshing with the rack 100 rotates in the direction opposite to the pulling direction of the rack 100, thereby driving the button placing strip 300 connected to the rotating gear 200 to rotate, so that different sides and the front of the buttons on the button placing strip 300 can be conveniently rotated to face the inkjet printer directly, facilitating the inkjet printer to conveniently spray ink on the front and side surfaces of the buttons.

[0063] The button printing fixture 10 is connected to the button placing strip 300 by the rotating gear 200. By pulling the rack 100 meshing with the rotating gear 200, the rotating gear 200 can be rotated in the direction opposite to the pulling direction of the rack 100, thereby driving the button placing strip 300 connected to the rotating gear 200 to rotate, and the angle adjustment of the button placing strip is realized simply and conveniently, so that the different sides and front of the buttons on the button placing strip 300 can be rotated to face the inkjet printer, so that the inkjet printer can conveniently spray ink to the front and side of the button to complete the simultaneous printing of the front and side of the button. The original fixture is padded to spray-paint the front and sides of the button. Pulling the rack 100 can realize the rotation of the button strip 300 at different angles. Therefore, when spraying buttons at different angles, there is no need to adjust the height of the fixture each time, which improves the efficiency of spraying. The padded fixture cannot accurately ensure that the padded thickness is the spraying angle required for the button. Pulling the rack 100 to drive the rotation of the rotating gear 200 can rotate the button strip 300 at any angle to realize the spraying of buttons at different angles. The corresponding parts of the buttons can be sprayed according to actual needs, which improves the accuracy of spraying.

[0064] In order to make the rotating gear 200 conveniently meshed with the rack 100 and connected to the second side plate 600, in a preferred embodiment, the rotating gear 200 includes a first rotating wheel 210 and a gear 220 sleeved on the first rotating wheel 210, the gear 220 meshes with the rack 100, and one end of the first rotating wheel 210 passes through the first through hole 410 and is rotatably connected to the first side plate 400. In the specific setting, the gear 220 is sleeved on one side of the first rotating wheel 210, and the side of the first rotating wheel 210 away from the gear 220 passes through the first through hole 410 and is rotatably connected to the first side plate 400. The first rotating wheel 210 can be transitionally matched with the first through hole 410, and the first rotating wheel 210 and the gear 220 can be fixedly connected by interference fit, welding or other methods, and the first rotating wheel 210 and the gear 220 can also be integrally formed, and the rack 100 drives the gear 220 to rotate so that the first rotating wheel 210 also rotates and rotates with the first side plate 400. The button strip 300 connected to the rotating wheel 210 rotates, and the first rotating wheel 210 is also provided with a U-shaped groove 211. The U-shaped groove 211 opens at the end surface where the first rotating wheel 210 and the button strip 300 are connected. The upper and lower groove walls of the U-shaped groove 211 are provided with a second through hole 212 that penetrates its wall thickness. The button strip 300 is also provided with a third through hole 320 that penetrates its thickness. The button strip 300 is inserted into the U-shaped groove 211, and the fastener passes through the second through hole 212 and the third through hole 320 to fix the first rotating wheel 210 and the button strip 300.

[0065] To enable the rotating gear 200 to rotate more stably, specifically, the button spraying fixture 10 further includes a second side plate 600 connected to the bottom plate 500. When specifically arranged, the button spraying fixture 10 includes a second fixing through hole 520, and the second fixing through hole 520 penetrates through the bottom plate 500 and the second side plate 600. A fastener passes through the second fixing through hole 520 to connect the bottom plate 500 and the second side plate 600 into a whole. The fastener can be a bolt, where:

[0066] The second side plate 600 is arranged at an interval from the first side plate 400. The second side plate 600 is located on the side of the first side plate 400 away from the button placing strip 300, and the second side plate 600 is provided with at least one fourth through hole 610. The fourth through hole 610 opens on the side surface of the second side plate 600. When specifically arranged, the second side plate 600 can be a cuboid, and generally the number of the fourth through holes 610 is set to be equal to the number of the rotating gears 200;

[0067] One end of the first rotating wheel 210 away from the button placing strip 300 passes through the fourth through hole 610 and is rotatably connected to the second side plate 600. When specifically arranged, the first rotating wheel 210 can be in transitional fit with the fourth through hole 610. Through the above arrangement, one end of the first rotating wheel 210 is fixed to the first side plate 400, and the other end of the first rotating wheel 210 is fixed to the second side plate 600. The gear 220 between the two ends of the first rotating wheel 210 meshes with the rack 100. When the rack 100 is pulled, the first side plate 400 and the second side plate 600 respectively provide supporting forces for the two ends of the first rotating wheel 210, ensuring the stable rotation of the gear 220.

[0068] To further enhance the rotational stability of the rotating gear 200, the second side plate 600 is arranged opposite to the first side plate 400, and the second side plate 600 and the first side plate 400 form an accommodating space for placing the rack 100. The fourth through hole 610 is arranged opposite to the first through hole 410. Through the above arrangement, when the rack 100 is pulled, the first side plate 400 and the second side plate 600 respectively provide symmetrical supporting forces for the two ends of the first rotating wheel 210, ensuring the more stable rotation of the gear 220.

[0069] In order to ensure the efficiency of spraying buttons, more specifically, the pulling direction of the rack 100 is the first direction a, the number of the first through holes 410 is multiple, the number of the first through holes 410 is equal to the number of the rotating gear 200 and the fourth through holes 610, and the multiple first through holes 410 are arranged at intervals along the first direction a, and the first through holes 410 and the fourth through holes 610 are opposite to each other one by one. In the specific setting, both ends of the rack 100 can be pulled, the number of the first through hole 410 and the fourth through hole 610 can be 2, 4, 5, 7, 9 or more, the length direction of the first side plate 400 and the second side plate 600 is consistent with the first direction a, and in specific use, each rotating gear 200 corresponds to a first through hole 410 and a fourth through hole 610 directly opposite to the first through hole 410, and multiple rotating gears 200 are arranged at intervals along the first direction a, and the rack 100 located between the first side plate 400 and the second side plate 600 is meshed with the gear 220 of each rotating gear 200, and the first rotating wheel 210 of each rotating gear 200 is connected to the button strip 300. When the rack 100 is pulled, multiple gears 220 will be driven to rotate simultaneously in a direction away from the first direction a, and the first rotating wheel 210 connected to the gear 220 will drive the button strip 300 to rotate, so that multiple button strips 300 can rotate at the same time and at the same angle, thereby improving the efficiency of inkjet printing.

[0070] In order to reduce the operating intensity of the workers, the clamp for spraying further includes a positioning pin 700 and a first positioning hole 620. When the rack 100 drives the gear 220 to rotate to the level of the button bar 300, the first positioning hole 620 penetrates the second side plate 600 and at least part of the rack 100, and the positioning pin 700 passes through the first positioning hole 620 to connect the second side plate 600 and the rack 100 as a whole. In specific use, the rack 100 is pulled, and when the rack 100 drives the gear 220 to make the button bar 300 horizontal, the positioning pin 700 is inserted to fix the rack 100 with the second side plate 600, which can eliminate the original method of using manpower to keep the rack 100 in the original position, freeing the workers' hands and reducing the operating intensity of the workers.

[0071] In order to fix the button strip 300 at a set angle, the button printing fixture further includes at least one positioning hole group, the positioning hole group includes a second positioning hole 110 and a third positioning hole 630, wherein:

[0072] The second positioning hole 110 is disposed on a side of the rack 100 close to the second side plate 600 , and the second positioning hole 110 is spaced apart from the first positioning hole 620 ;

[0073] The third positioning hole 630 opens on the surface of the second side plate 600 facing the rack 100 and penetrates the thickness of the second side plate 600. The third positioning hole 630 is spaced apart from the first positioning hole 620.

[0074] The second positioning hole 110 is located at one end of the third positioning away from the first direction a;

[0075] The distance between the axis of the second positioning hole 110 and the axis of the third positioning hole 630 along the first direction a is a set distance;

[0076] When the rack 100 moves a set distance along the first direction a, the corresponding button releasing bar 300 rotates from the horizontal state to a set angle.

[0077] In specific settings, during the inkjet printing process, to achieve a good inkjet printing effect on the button, it is often necessary to inkjet the button at different angles. The angle at which the button releasing bar 300 rotates according to the above actual required angle is the set angle. The set angle can be any angle from 0° to 360°, such as 15°, 30°, 45°, 60°, etc. For example, when the set angle is 15°, pull the rack 100 to drive the gear 220 to rotate so that the button releasing bar 300 rotates from the horizontal state, i.e., 0°, to 15°. Measure the distance that the rack 100 moves. This distance is also the set distance that the rack 100 needs to move when the button releasing bar 300 rotates from 0° to the set angle of 15°. Or calculate the circumference of the gear 220 based on the radius of the gear 220. In this example, 1 / 24 of the circumference is the set distance that the rack 100 needs to move when the button releasing bar 300 rotates from 0° to the set angle of 15°. When the distance between the axis of the second positioning hole 110 and the axis of the third positioning hole 630 along the first direction a is set to the set distance, it is ensured that after the rack 100 moves the set distance, the second positioning hole 110 and the third positioning hole 630 are in a facing state. In specific use, pull out the positioning pin 700 from the first positioning hole 620, pull the rack 100 to move the set distance. When the gear 220 rotates by the set angle of 15° from 0°, at the same time, make the second positioning hole 110 and the third positioning hole 630 face each other. At this time, insert the positioning pin 700 into the second positioning hole 110 and the third positioning hole 630 to fix the rack 100, so that the inkjet printer can inkjet the button at this angle to obtain a good inkjet printing effect.

[0078] To improve the efficiency of button inkjet printing, further, the number of positioning hole groups is multiple, and each positioning hole group corresponds to a set angle. In specific settings, the number of positioning hole groups can be 3, 4, 5 or more. For example, when the number of positioning hole groups is 5, the number of set angles can be 5, where:

[0079] The multiple positioning hole groups are arranged at intervals along the first direction a, and the set angles corresponding to the multiple positioning hole groups along the first direction a gradually increase. In specific settings, both the second positioning hole 110 and the third positioning hole 630 are distributed along the first direction a and the number is equal. In specific use, for example, when the number of positioning hole groups is 4, the set angles corresponding to the positioning hole groups along the first direction a can be 15°, 30°, 45°, 60° in sequence;

[0080] The difference between the two set distances corresponding to any two positioning groups is the distance that the button bar 300 moves along the first direction a when rotating from the first angle to the second angle corresponding to the rack 100.

[0081] The first angle is the set angle corresponding to the one far from the first direction a among any two positioning groups, and the second angle is the set angle corresponding to the other one among two adjacent positioning groups. For example, when the button bar 300 needs to rotate from 15° to 45°, the difference between the set distance when the button bar 300 rotates from 0° to 45° and the set distance when the button bar 300 rotates from 0° to 15° is the distance that the button bar 300 moves along the first direction a when rotating from 15° to 45°. When specifically setting, first measure or calculate the set distances corresponding to various set angles to which the button bar 300 needs to rotate, and then set the distance along the first direction a between the axes of the second positioning holes 110 and the third positioning holes 630 in each group of positioning holes corresponding to each set angle to the obtained set distance. Through the above settings, the rotation angles of the commonly used button bar 300 can be conveniently fixed, and the efficiency of button spraying is improved.

[0082] In order to make the button bar 300 more stable, in a preferred embodiment, the button spraying fixture 10 further includes a second runner and a third side plate 800 connected to the bottom plate 500. When specifically setting, the button spraying fixture 10 includes a third fixing through hole 530, the third fixing through hole 530 penetrates through the bottom plate 500 and the third side plate 800, and a fastener passes through the third fixing through hole 530 to connect the bottom plate 500 and the third side plate 800 into a whole. The fastener can be a threaded rod, and the third fixing through hole 530 is provided with threads, where:
