[0001] The present invention relates to the technical field of zipper head spraying, in particular to a clean and reduced-volume paint spraying machine capable of spraying by turning and spraying, and a method for using the same. Background Art

[0002] The zipper head is the main component used with the zipper. During the production and processing, the zipper head needs to be painted according to production requirements, so that the zipper head can have different colors and can be used on different clothes.

[0003] There are many existing technologies for zipper head spray painting, such as:

[0004] Chinese patent publication number CN110064555B discloses an automated production device for cleaning, drying and painting zipper heads. The key points of its technical solution include a frame, on which a rotating component, a moving component, a flushing component, a spraying component and a baking component are respectively provided. The frame is provided with a hanger for fixing the zipper head, the hanger is fixed on the rotating component, and the flushing component and the spraying component are respectively located on both sides of the baking component; the zipper head is installed on the hanger, the hanging rack is driven to move by the moving component, the cleaning component flushes the hanger, the rotating component rotates the hanger, the baking component dries the zipper head, the spraying component paints the zipper head, the rotating component rotates the hanger, and the spraying component sprays the zipper head again. After spraying, the moving component drives the rotating component to return and move to the bottom of the baking component, the baking component dries the zipper head, and finally the zipper head is output, thereby reducing the workload of workers in carrying zipper heads and improving work efficiency.

[0005] The existing structure for spraying paint on zipper heads mostly adopts a combination of hoisting spraying and hanger rotation to ensure that the zipper head can be sprayed evenly. Among them, when the zipper is fixed, an expansion spring sheet is usually inserted into the zipper head to fix the zipper head. Chinese Patent Publication No. CN110064555B is horizontally mounted, and Chinese Patent Publication No. CN113385333B is vertically mounted. Since the zipper head is fixed during the rotation of the hanger, the zipper head and the pull tab are in an active state. When the horizontally mounted zipper head rotates to the top, the pull tab contacts the zipper head and blocks the surface of the zipper head, resulting in a shadow area. Similarly, the vertically mounted pull tab will also cause obstruction, thereby affecting the uniformity of spraying on the zipper head surface. Summary of the Invention

[0006] The object of the present invention is to provide a clean and reduced-weight paint sprayer that sprays by flipping and a method of use to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention aims to provide a clean and reduced-volume paint sprayer by flipping and spraying, comprising a base, a spray bracket and a rotating bracket vertically on the rotating bracket, wherein a paint supply device is provided on the spray bracket, and the bottom of the rotating bracket is driven to rotate by a motor, and a plurality of convex plates are fixedly connected to the outer ring of the rotating bracket, and each convex plate is provided with a mounting mechanism for fixing the zipper head, and a toggle plate and an auxiliary rod are sequentially provided at the bottom of the convex plate from top to bottom, wherein the auxiliary rod is fixedly connected to the spray bracket, and a magnetic attraction mechanism for attracting the pull tab is provided inside the auxiliary rod. When the rotating bracket rotates, the toggle plate is used to squeeze the magnetic attraction mechanism to break the balance state of the mounting mechanism, so that a spray angle is formed between the zipper head and the pull tab, and the adsorption mechanism pulls the air guide plate slidingly arranged inside the convex plate to move, and the air guide plate gradually forms an inclined shape and guides the paint to the spray angle, so as to realize spraying on the surface of the zipper nozzle.

[0008] As a further improvement of this technical solution, the mounting mechanism includes an elastic ring, which is fixed on the movable plate. The elastic ring is U-shaped, with the open end contracted inward and the two sides of the bent end being flat and resting against the seam of the cloth bag to limit the shaking of the zipper head.

[0009] As a further improvement of this technical solution, the bottom of the movable plate is rotatably connected to a support seat, an arc spring is elastically connected between the support seat and the movable plate, the bottom of the support seat is fixedly connected to the convex plate, and a through groove is formed on the convex plate between the support seats on both sides for the air guide plate to escape.

[0010] As a further improvement of this technical solution, the upper end of the toggle plate is fixed to the bottom of the convex plate, and the bottom of the toggle plate away from the convex plate is inclined, so that the magnetic attraction mechanism slides downward along the inclined surface during the rotation of the toggle plate.

[0011] As a further improvement of the present technical solution, the magnetic attraction mechanism includes a first magnet slidably arranged inside the auxiliary rod, the first magnet is connected to one end of the first traction rope, the other end of the first traction rope is connected to a reciprocating rod slidably connected to the auxiliary rod, and a protruding rod extending outward is fixedly provided on the outer ring at the top of the reciprocating rod. The protruding rod is located on the path of rotation of the inclined surface of the toggle plate, so as to provide downward force for the protruding rod to move downward when the inclined surface of the toggle plate contacts the protruding rod.

[0012] As a further improvement of the present technical solution, compression springs are provided at both ends of the first traction rope. Under normal conditions, the compression spring close to the reciprocating rod is in a released state, and the compression spring close to the first magnet is in a compressed state.

[0013] As a further improvement of the present technical solution, it also includes an adsorption mechanism, which includes two second magnets that are magnetically attracted to each other, and the lower second magnet is fixed to the reciprocating rod, wherein an elastic rope for limiting the second magnet is elastically connected between the upper second magnet and the toggle plate, and the upper second magnet is fixedly connected to one end of the V-shaped second traction rope, and the other end of the second traction rope is fixedly connected to the inside of the convex plate.

[0014] As a further improvement of this technical solution, a reset spring is elastically connected between one side of the air guide plate and the inner wall of the convex plate. The two sides of the air guide plate are rotatably connected to the baffle rod, and the baffle rod is close to the reset spring. Under normal circumstances, the two ends of the second traction rope expand outward, and the bending position bypasses the baffle rod on the side of the air guide plate.

[0015] As a further improvement of the present technical solution, a wedge block is provided at one end of the air guide plate away from the return spring, and the wedge block is fixedly connected to the inside of the convex plate. When the end of the air guide plate slides beyond the top of the wedge block, the air guide plate guides the paint sprayed onto the back of the pull tab to the shadow area of ​​the zipper head and the inside of the zipper head, so that the paint is evenly covered in the shadow area of ​​the zipper head and the inside of the zipper head.

[0016] The second object of the invention is to provide a method for operating the above-mentioned clean-reduction paint sprayer by flip spraying, comprising the following method steps:

[0017] S1. Place a zipper head on each mounting mechanism. The zipper head is supported by the mounting mechanism to prevent the zipper head from loosening. Then, the motor drives the rotating frame to rotate to achieve the spraying of the zipper head.

[0018] S2. When the toggle plate applies pressure to the magnetic attraction mechanism, the magnetic attraction mechanism is used to break the balance between the zipper head and the pull tab, so that a jet angle is formed between the zipper head and the pull tab, exposing the shadow area;

[0019] S3. As the magnetic attraction mechanism moves downward, the air guide plate moves and guides the paint sprayed from the nozzle on the back of the zipper head to the shadow area and the inside of the zipper head one by one, so that the paint evenly covers its surface.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the clean and reduced-volume paint sprayer that sprays by flipping, the first magnet is used to break the balance between the zipper head and the pull tab, so that a spray angle is formed between the zipper head and the pull tab. At the same time, the movement of the first magnet will indirectly drive the second traction rope to push the air guide plate to move. The end of the air guide plate slides along the wedge block. When the end of the air guide plate slides beyond the top of the wedge block, the air guide plate guides the paint sprayed onto the back of the pull tab to the shadow area of ​​the zipper head and the inside of the zipper head, so that the paint is evenly covered in the shadow area of ​​the zipper head and the inside of the zipper head.

[0022] 2. In the clean and reduced-volume paint sprayer that sprays by flipping, the two sides of the bent end are flat-shaped and pressed against the seam of the cloth bag. This not only restricts the zipper head to prevent it from shaking during spraying, but also the flat position can reduce the contact area with the zipper head and increase the adhesion area of ​​the paint.

[0037] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] 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 the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0040] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, a clean and reduced-volume paint sprayer that sprays by flipping is provided, comprising a base 100, a spraying bracket 101, and a rotating bracket 102 disposed on the spraying bracket 101. A paint supply device is disposed on the spraying bracket 101, and the bottom of the rotating bracket 102 is driven by a motor to rotate so as to achieve uniform spraying of the zipper head.

[0041] A plurality of convex plates 120 are fixedly connected to the outer ring of the rotating frame 102, and each convex plate 120 is provided with a mounting mechanism 110 for fixing the zipper head. A toggle plate 121 and an auxiliary rod 103 are sequentially provided at the bottom of the convex plate 120 from top to bottom, wherein the auxiliary rod 103 is fixedly connected to the spray bracket 101, and a magnetic attraction mechanism 130 for attracting the pull tab is provided inside the auxiliary rod 103. When the rotating frame 102 rotates, the toggle plate 121 is used to squeeze the magnetic attraction mechanism 130 to break the balance state of the mounting mechanism 110, so that a spray angle is formed between the zipper head and the pull tab, and the adsorption mechanism pulls the air guide plate 140 slidingly arranged inside the convex plate 120 to move, and the air guide plate 140 gradually forms an inclined shape and guides the paint to the spray angle, so as to realize spraying on the surface of the zipper nozzle.

[0042] First, when spraying the zipper head, the zipper head is first fixed on the mounting mechanism 110, and then the multiple rotating frames 102 are rotated by the motor. When the zipper head on each mounting mechanism 110 rotates between the nozzles, the paint supply device delivers paint to the nozzle and sprays the front and back sides of the zipper head. The double-sided one-time spraying method can save spraying time and improve work efficiency.

[0043] It should be noted that the front and back sides of the zipper head mentioned above are Figure 5 For example, the position of the pull tab is the front side, and vice versa.

[0044] Therefore, based on the above diagram, combined with Figure 3 As shown, the structure of the mounting mechanism 110 is first described. The mounting mechanism 110 includes an elastic ring 111, which is fixed to the movable plate. The elastic ring 111 is U-shaped, with the open end contracted inward and the two sides of the bent end being flat and pressed against the seam of the bag to limit the shaking of the zipper head. Figure 4 As shown, the bottom of the movable plate is rotatably connected to a support seat 112, an arc spring 113 is elastically connected between the support seat 112 and the movable plate, the bottom of the support seat 112 is fixedly connected to the convex plate 120, and a through groove is formed on the convex plate 120 between the support seats 112 on both sides for the air guide plate 140 to escape.

[0045] When in use, first press the cloth bag seam of the zipper head against the flat position of the bent end, so that the bent end contacts the upper and lower base plates of the zipper head. In other words, using the flat ends on both sides of the bent end to press against the cloth bag seam can not only restrict the zipper head and prevent it from shaking during spraying, but also the flat position can reduce the contact area with the zipper head and increase the adhesion area of ​​the paint.

[0046] As the rotating frame 102 rotates, when the zipper head on the elastic ring 111 rotates to the spraying area (that is, Figure 2During this process, the toggle plate 121 at the bottom of the convex plate 120 will press the magnetic attraction mechanism 130 inside the auxiliary rod 103 to break the balance between the zipper head and the pull tab. It is worth noting that when the zipper head has not yet rotated to the spraying area, the state of the zipper is Figure 5 As shown, the pull tab is in a vertical state, that is, the chain head and the pull tab are in a balanced state.

[0047] Then, the nozzle sprays the front and back sides of the zipper head. At the same time, the paint sprayed by the front nozzle can also cover the surface of the pull tab, and the upper end of the toggle plate 121 is fixed to the bottom of the convex plate 120. The bottom of the toggle plate 121 away from the convex plate 120 is inclined, so that when the toggle plate 121 rotates, the magnetic attraction mechanism 130 slides downward along the inclined surface.

[0048] Furthermore, the specific structure of the magnetic mechanism 130 is disclosed. The magnetic mechanism 130 includes a first magnet 131 slidably arranged inside the auxiliary rod 103, the first magnet 131 is connected to one end of the first traction rope 134, and the other end of the first traction rope 134 is connected to a reciprocating rod 133 slidably connected to the auxiliary rod 103, and a protruding rod 133a extending outward is fixedly provided on the top outer ring of the reciprocating rod 133. The protruding rod 133a is located on the path of the inclined surface of the toggle plate 121 to provide downward pressure for the protruding rod 133a to move downward when the inclined surface of the toggle plate 121 contacts the protruding rod 133a.

[0049] In addition, when the reciprocating rod 133 moves downward, in order to make the pull tab change from a vertical state to an inclined state so as to form a spray angle between the zipper head and the pull tab, so as to block the zipper head surface paint from the pull tab later, compression springs 135 are provided at both ends of the first traction rope 134. Under normal conditions, the compression spring 135 close to the reciprocating rod 133 is in a released state, and the compression spring 135 close to the first magnet 131 is in a compressed state. Therefore, the toggle plate 121 presses the reciprocating rod 133 downward and overcomes the elastic potential energy of the compression spring 135 at the bottom of the reciprocating rod 133, and the reciprocating rod 133 moves downward (refer to FIG. Figure 5 The compression spring 135 close to the first magnet 131 pushes the first magnet 131 to move in the horizontal direction (pointed by the arrow g). As the first magnet 131 moves, the state of the zipper head and the pull tab gradually changes to Figure 8 In the state shown in , a jet angle is formed between the zipper head and the pull tab, and the vertical angle corresponding to the jet angle is Q.

[0050] At the same time, the first magnet 131 overcomes the attraction of the pull tab during the movement. Figure 4 The elastic potential energy of the middle arc spring 113 causes the elastic ring 111 to rotate clockwise, and the slider is blocked and a shadow area is generated on the surface of the zipper slider (refer to Figure 8 as shown) to facilitate subsequent paint adhesion.

[0051] In order to improve the adhesion of the paint, when spraying, use the reverse nozzle to spray the reverse side of the zipper head while spraying the inside of the zipper head and the shadow area. This not only saves the number of spraying times and reduces paint waste, but also improves the adhesion of the paint, so that the paint can be evenly attached to the zipper head. Figure 7 Combined with Figure 6 As shown, the device also includes an adsorption mechanism, which includes two second magnets 132 that magnetically engage each other. The lower second magnet 132 is fixed to a reciprocating rod 133. An elastic cord 137 is elastically connected between the upper second magnet 132 and the toggle plate 121 to restrain the second magnet 132. The upper second magnet 132 is fixedly connected to one end of a V-shaped second traction cord 136, the other end of which is fixedly connected to the interior of the protruding plate 120. Meanwhile, a return spring 141 is elastically connected between one side of the air guide plate 140 and the inner wall of the protruding plate 120. Both sides of the air guide plate 140 are rotatably connected to a barrier rod, which is close to the return spring 141. Under normal conditions, the two ends of the second traction cord 136 expand outward, and the bent position bypasses the barrier rod on the side of the air guide plate 140.

[0052] Working Principle: When the upper and lower second magnets 132 are not yet attracted, the upper second magnet 132 maintains a balanced state under the combined action of the second traction rope 136 and the protruding rod 133a. As the protruding plate 120 rotates, the upper and lower second magnets 132 attract each other, and the toggle plate 121 applies pressure to the protruding rod 133a, causing the reciprocating rod 133 to move downward. To increase the attraction between the second magnets 132, the lower second magnet 132 can also be configured as an electromagnet to enhance the attraction between the two. In this way, the mutually attracted second magnets 132 overcome the elastic potential energy of the elastic rope 137 and the return spring 141.

[0053] Because one end of the second traction rope 136 is fixed to the convex plate 120 , according to the force decomposition, the second traction rope 136 has a component force in the horizontal direction to push the air guide plate 140 to move, thereby providing power for the movement of the air guide plate 140 .

[0054] Considering that the paint sprayed from the nozzle on the back of the zipper head will not be completely sprayed onto the surface of the zipper head, there will be a waste of paint. If it is utilized, it can ensure the accurate use of paint and save resources. Therefore, a wedge block 120a is provided at one end of the air guide plate 140 away from the return spring 141. The wedge block 120a is fixedly connected to the inner part of the convex plate 120, and then combined with the Figure 7 As shown, the air guide plate 140 gradually moves from the horizontal state to the state shown by the dotted line position, and Figure 8The spraying state is displayed, that is, the first magnet 131 is used to break the balance state of the zipper head and the pull tab, so that a spray angle is formed between the zipper head and the pull tab. At the same time, the movement of the first magnet 131 will also indirectly drive the second traction rope 136 to push the air guide plate 140 to move. The end of the air guide plate 140 slides along the wedge block 120a. When the end of the air guide plate 140 slides to exceed the top of the wedge block 120a, the air guide plate 140 guides the paint sprayed to the back of the pull tab to the shadow area of ​​the zipper head and the inside of the zipper head, so that the paint is evenly covered in the shadow area of ​​the zipper head and the inside of the zipper head.

[0055] Finally, when the second magnets 132 are separated, the air guide plate 140 is pulled in the reverse direction to return to its original position under the action of the return spring 141 , and then the spraying work of the next zipper head is carried out.

[0056] A second object of the present invention is to provide a method for using a clean, weight-reducing paint sprayer by flipping and spraying, comprising the following steps:

[0057] S1. Place a zipper head on each mounting mechanism 110. The zipper head is supported by the mounting mechanism 110 to prevent the zipper head from loosening. Then, the motor drives the rotating frame 102 to rotate to achieve the spraying of the zipper head.

[0058] S2. When the toggle plate 121 applies pressure to the magnetic attraction mechanism 130, the magnetic attraction mechanism 130 breaks the equilibrium between the zipper head and the pull tab, forming a jet angle between the zipper head and the pull tab, exposing the shadow area;

[0059] S3. When the magnetic attraction mechanism 130 moves downward, the air guide plate 140 moves and guides the paint sprayed from the nozzle on the back of the zipper head to the shadow area and the inside of the zipper head one by one, so that the paint evenly covers the surface.

[0060] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
