Description

Technical Field

[0001] The invention relates to the technical field of spraying, in particular to a sewing machine head hoisting spraying device. Background Art

[0002] The sewing machine head is a special processing device for fabric products. It consists of four parts: head, base, transmission and accessories. The head is the core component of the sewing machine. It mainly sews single or multiple sewing threads along the trajectory to make finished fabric products.

[0003] Due to the special structure of the sewing machine head nowadays, the head and base of most sewing machines are an integrated structure. When the head and base are directly sprayed in an exposed environment, they are affected by the ambient airflow and the airflow formed at the moment of paint mist spraying. The paint mist will first be printed on the parts close to the head and base. As the paint spraying equipment turns along the head and base, the printed paint film will produce pores due to construction, and then form pit defects. At the same time, the thickness of the paint layer will also produce a gradient texture due to the residence time of the paint spraying equipment, thereby affecting the surface finish of the head and base.

[0004] In view of this, the present invention designs a sewing machine head hoisting spraying device to solve the above problems. Summary of the invention

[0014] The anti-skid pad is made of rubber material, and the inner end of the anti-skid pad is provided with an anti-skid rough surface.

[0015] In a preferred example, the present invention can be further configured as follows: the limit frame plate is in a U-shaped structure as a whole, and two scale rulers are installed on the plate surface at the top of the limit frame plate.

[0016] In a preferred example, the present invention can be further configured as follows: the spray assembly includes a high-pressure end tube, a compression spring arranged outside the high-pressure end tube, and a clamp installed on the high-pressure end tube;

[0017] The inner cavity of the high-pressure end pipe is equipped with an atomizing nozzle.

[0018] In a preferred example, the present invention can be further configured as follows: two symmetrically distributed feet are installed on both sides of the chuck, two beams are respectively installed in the two groups of the feet, and a nozzle is connected to the outer end of the high-pressure end pipe.

[0027] 2. The present invention sets up two independent molds that can accurately package the machine head and the machine base. As the molds are closed, the auxiliary pressure component can press the two closed molds. At this time, the inner cavities of the two closed molds can provide anti-seepage protection for the ventilation airflow. When the inside of the mold is in a pressurized state, the paint mist in a vacuum state will be guided outward by the airflow sequence, thereby reducing the problem of uneven thickness of the local paint layer on the machine head and the machine base.

[0041] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0042] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0043] A sewing machine head hoisting spraying device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] Combination Figure 1-Figure 8 As shown, the present invention provides a sewing machine head hoisting spraying device, which includes a sewing machine head 400, a paint mist drainage and evenly coating mechanism 300 arranged outside the sewing machine head 400, a mold opening and closing mechanism 200 installed on the paint mist drainage and evenly coating mechanism 300, and an anti-seepage pressing mechanism 100 installed on the mold opening and closing mechanism 200.

[0046] The anti-seepage pressing mechanism 100 includes a limit frame 110, an end column 120, an auxiliary pressure assembly 130, a base 140, a hydraulic component 150, a clamp seat 160, a traction frame 170 and a bracket 180, and the auxiliary pressure assembly 130 also includes a top support rod 131, an anti-slip gasket 132 and a reinforcing compression spring 133. The mold opening and closing mechanism 200 includes a spray assembly 210, a base 220, a hexagonal nut 230, a pull rod 240, a nozzle 250, a pad 260 and a crossbeam 270, and the spray assembly 210 also includes a high-pressure end pipe 211, a compression spring 212 and a chuck 213. The paint mist drainage and evenly covering mechanism 300 includes a first mold 310, a second mold 320, a cushion block 330, an adapter 340, a protective tube 350 and an exhaust pipe 360, and the sewing machine head 400 is arranged in two rectangular cavities of the first mold 310 and the second mold 320 after closing.

[0047] The anti-seepage pressing mechanism 100 includes two limit frame plates 110, two end columns 120 installed in the two limit frame plates 110, an auxiliary pressure assembly 130 installed in the end column 120, a base 140 installed in the middle of the two limit frame plates 110, a hydraulic component 150 installed inside the base 140, a clamping seat 160 installed on a hydraulic sub-rod in the hydraulic component 150, two traction frames 170 movably connected to the clamping seat 160, and a bracket 180 movably installed on the top of the traction frame 170;

[0048] The mold opening and closing mechanism 200 includes a spraying assembly 210 for guiding the spraying of paint, a base 220 disposed on the spraying assembly 210, and two pull rods 240 movably connected to the base 220;

[0049] The paint mist drainage and uniform coating mechanism 300 includes a first mold 310 and a second mold 320 which are arranged in two limiting frame plates 110 .

[0050] Since the head and base of most sewing machines nowadays are an integrated structure, and the structures of the head and base are different, when painting is carried out directly in the paint spraying room, airflow will be generated around the head and base at the moment when the paint spraying equipment releases the paint mist instantly. At the same time, interfering airflow is also likely to be generated in the paint spraying room. When the paint spraying equipment sprays on the head and base, it will be affected by the airflow and cause the paint mist to form a paint layer of gradually varying thickness on the surface of the head and base. At the same time, the paint layer is also prone to produce bubbles due to sputtering, which will further affect the smoothness of the paint layer on the surface of the head and base.

[0051] When the device is in use, the first mold 310 and the second mold 320 are set as independent molds for spraying paint on the sewing machine head 400. After the first mold 310 and the second mold 320 of the filing cabinet are closed, the two sets of auxiliary pressure components 130 can cooperate with the two limit frame plates 110 to press and fix the closed first mold 310 and the second mold 320. When the two nozzles 250 inject paint into the two high-pressure end pipes 211, the paint mist in the supercharged state will be released to the inner cavity of the first mold 310 and the second mold 320 after closing. When the exhaust pipe 360 ​​initially discharges air to the outside, the inner cavity of the first mold 310 and the second mold 320 will be in a vacuum state, and the paint mist subsequently released into the vacuum cavity will be evenly sprayed on the surface of the sewing machine head 400, thereby avoiding the problem of pores in the paint film due to the interference of airflow, and at the same time reducing the paint splashing and spraying to cause a gradual change in the thickness of the paint layer on the surface of the sewing machine head 400.

[0052] Embodiment 2:

[0053] Combination Figure 3-Figure 8 As shown, on the basis of embodiment 1, the auxiliary pressure assembly 130 includes a top support rod 131 movably installed in the end column 120, an anti-slip pad 132 fixedly installed at the inner end of the top support rod 131, and a reinforcing compression spring 133 connected to the end column 120 and the top support rod 131;

[0054] The anti-skid pad 132 is made of rubber material, and the inner end of the anti-skid pad 132 is provided with an anti-skid rough surface;

[0055] The limiting frame plate 110 is in a U-shaped structure as a whole, and two scale rulers are installed on the plate surface at the top of the limiting frame plate 110;

[0056] Two locking bolts are installed in two end plates at the bottom of the base 140 , and the two locking bolts are used to fasten the hydraulic component 150 .

[0057] By fixing one end of the reinforcing compression spring 133 on the inner end of the end column 120 and installing the other end of the reinforcing compression spring 133 on the column head at the inner end of the top support rod 131, when the first mold 310 and the second mold 320 extend outward along the inner sides of the two limit frame plates 110, the two compressed reinforcing compression springs 133 can accumulate elastic potential energy for restoration. When the sewing machine head 400 is placed inside the first mold 310 and the second mold 320, the two reinforcing compression springs 133 can press and fix the closed first mold 310 and the second mold 320. At this time, the inner cavity of the first mold 310 and the second mold 320 can facilitate the exhaust of the exhaust pipe 360 ​​to the outside to form a vacuum state, thereby facilitating the rapid coating of the sewing machine head 400 surface with paint mist.

[0058] Embodiment 3:

[0059] Combination Figure 5-Figure 8 As shown, based on Example 1, the spray assembly 210 includes a high-pressure end pipe 211, a compression spring 212 disposed outside the high-pressure end pipe 211, and a clamp 213 installed on the high-pressure end pipe 211;

[0060] The inner cavity of the high-pressure end pipe 211 is equipped with an atomizing nozzle;

[0061] Two symmetrically distributed feet 260, two crossbeams 270 respectively installed in the two groups of feet 260, and a nozzle 250 connected to the outer end of the high-pressure end pipe 211 are installed on both sides of the clamp 213;

[0062] The base 220 is composed of a threaded tube, a sliding column, two end plates, and two plug rods installed in the two end plates, and a hexagonal nut 230 for locking and fastening the bracket 180 is movably installed outside the threaded tube.

[0063] By setting the two high-pressure end tubes 211 in the middle of the closed path of the first mold 310 and the second mold 320, when the first mold 310 and the second mold 320 are in a closed state, the inner ends of the two high-pressure end tubes 211 can be connected with the inner cavities of the first mold 310 and the second mold 320. After the two nozzles 250 inject high-pressure paint, the paint mist sprayed from the atomizing nozzle inside the high-pressure end tube 211 can be evenly released to the vacuumed cavity of the first mold 310 and the second mold 320. When the paint mist diffuses in the vacuumed cavity, the subsequent exhaust pipe 360 ​​can guide the diffused paint mist to the outside, so that the paint can be evenly sprayed on the surface of the sewing machine head 400, thereby ensuring the smoothness of the paint layer after spraying.

[0064] Embodiment 4:

[0065] Combination Figure 2-Figure 8 As shown, in the above embodiment, the paint mist drainage and uniform coating mechanism 300 further includes two protective tubes 350, and one of the protective tubes 350 is fixedly mounted on the first mold 310, and the other protective tube 350 is fixedly mounted on the second mold 320;

[0066] An exhaust pipe 360 ​​for discharging air is installed in the two protective tubes 350;

[0067] A rectangular cavity is formed inside the first mold 310 and the second mold 320, and two sets of cushion blocks 330 are installed in the rectangular cavity;

[0068] Both ends of the first mold 310 and the second mold 320 are installed with studs and nuts;

[0069] The paint mist drainage and uniform coating mechanism 300 further includes four adapters 340 , two of which are mounted on multiple studs at both ends of the first mold 310 , and the other two adapters 340 are mounted on multiple studs at both ends of the second mold 320 .

[0070] By movably connecting the four pull rods 240 to the four adapters 340 respectively, when the bracket 180 is compressed and drives the base 220 to move horizontally along the rod body of the high-pressure end tube 211, the two adjacent pull rods 240 will expand at the same speed, thereby prompting the first mold 310 and the second mold 320 to move at the same speed inside the two limit frame plates 110, and cooperate with the scale ruler on the top plate of the limit frame plate 110 to monitor the distance after movement, thereby ensuring that the sewing machine head 400 is placed in the center of the inner cavity of the first mold 310 and the second mold 320 after closing, so as to facilitate the subsequent spraying of paint mist on the surface of the centered sewing machine head 400.

[0071] The working principle and use process of the present invention are as follows: the hydraulic component 150 is operated in advance, and after the internal hydraulic sub-rod thereof extends downward, the clamp seat 160 installed at the bottom end of the hydraulic sub-rod will simultaneously drive the two traction frames 170 to expand downward, and at this time, the traction frame 170 will cooperate with the bracket 180 to drive the base 220 and the hexagonal nut 230 to move inwardly, and at this time, the two pull rods 240 movably installed on the base 220 will respectively open the closed first mold 310 and the second mold 320 outward until the first mold 310 and the second mold 320 expose the largest gap, and then place the sewing machine head 400 to be painted along the gap in the groove on the inner side of the first mold 310 or the second mold 320, and then control the hydraulic component 150 to run in the reverse direction until the internal hydraulic sub-rod thereof extends upward, and at this time, the bottom end of the hydraulic sub-rod is installed The clamping seat 160 will drive the two traction frames 170 to lift upwards. At the same time, the two compressed brackets 180 will drive the base 220 and the hexagonal nut 230 to extend outwards along the rod body of the high-pressure end tube 211. At this time, the two pull rods 240 movably installed on the base 220 can apply a balanced closing force to the first mold 310 and the second mold 320 until the first mold 310 and the second mold 320 are completely closed. At this time, the sewing machine head 400 will be in the cavity inside the first mold 310 and the second mold 320 after closing. At this time, the two high-pressure end tubes 211 will be connected with the inner cavity of the first mold 310 and the second mold 320 after closing, and the exhaust pipe 360 ​​installed in the two protective tubes 350 can guide the paint mist entering the inner cavity of the first mold 310 and the second mold 320 to ventilate outwards;

[0072] After the two nozzles 250 transfer the paint to the inside of the two high-pressure end tubes 211, the paint in a high-pressure state will be sprayed by the nozzle in the inner cavity of the high-pressure end tube 211 toward the inner cavities of the first mold 310 and the second mold 320 after closing, and the incoming paint mist will be guided outward by the ventilation of the exhaust pipe 360. According to the ventilation path planned in the internal cavities of the first mold 310 and the second mold 320 after closing, the paint mist can be evenly coated on the surface of the sewing machine head 400, thereby avoiding the gradual bulge of the local paint layer due to the head being exposed to the external environment and being affected by the airflow.

[0073] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
