[0015] The beneficial effects of the present invention are:

[0016] 1. In the embodiment of the present invention, the distance between two adjacent groups of exhaust pipes 2 gradually decreases from the middle to the sides. Due to the change in distance, the corresponding exhaust intensity above the windshield gradually increases from the middle to the sides. When the screen printing mechanism quickly presses down to print, an offset force is generated from above. The gradual change of the exhaust intensity at different positions below can smooth the clothing, quickly offsetting the offset force and ensuring the flatness of the clothing, thereby improving the actual screen printing operation effect.

[0017] 2. In the embodiment of the present invention, the circulation cavity in the windshield maintains the circulation of cold air, which continuously cools the interior of the support box and the lower part of the garment, while hot air is blown downward from the bottom of the movable blower pipe to smooth the garment, thereby creating a relative temperature difference between the upper and lower parts of the garment. The temperature difference between the upper and lower parts increases the downward airflow movement effect, thereby reducing the impact of the upward rebound squeezing airflow generated by the rapid descent of the screen printing mechanism on the garment, thereby further ensuring the flatness and stability of the garment during the screen printing operation.

[0018] 3. In the embodiment of the present invention, after the garment is in place, the rapid movement of the blower tube and the rapid sequential energization of the two electromagnetic blocks cause the extrusion bars at both ends to press down the garment in a variable speed manner, thereby avoiding wrinkle deviation at the extrusion position. The variable speed downward pressure at both ends ensures the flatness of the garment at the middle position corresponding to the screen film, thereby cooperating with the suction airflow from below to improve the actual overall screen printing operation effect.

DETAILED DESCRIPTION

[0035] Example 1

[0036] Reference Figure 1-Figure 3 A clothing screen printing device includes a base 1, a liftable screen printing mechanism 2 is provided above the base 1, the screen printing mechanism 2 is set to the two ends of the reciprocating printing direction, a support box 7 is provided in the middle position of the top of the base 1, and an air suction hole 10 is opened on the top of the support box 7;

[0037] Figure 3-Figure 6 The bottom end of the support box 7 is provided with a detachably connected bottom plate 701, and partitions 8 are fixed at both ends of the support box 7. The partitions 8 are extended in both directions. A plurality of horizontally placed wind shields 9 are fixed between the two partitions 8. The wind shields 9 are extended in both directions. The width of the wind shields 9 gradually decreases from the middle position to both sides, and the distribution area of ​​the air suction holes 10 is adapted to the cross-section of the wind shield 9.

[0038] Reference Figure 7 , a plurality of exhaust pipes 11 are connected to the middle position of the bottom of the support box 7, and the plurality of exhaust pipes 11 are extended and distributed along the two ends. A plurality of exhaust pipes 12 are provided at the positions on both sides of the wind shield 9 at the bottom of the support box 7. The exhaust pipe 11 and the exhaust pipe 2 12 are connected to the exhaust fan through a plurality of air ducts. Control valves are provided on the plurality of air ducts. The exhaust intensity of the exhaust pipe 11 is greater than the exhaust intensity of the exhaust pipe 2 12.

[0039] Reference Figure 1-Figure 2In actual use, the garment to be printed is laid on the base 1 at a position corresponding to the support box 7, and the suction holes 10 at the top of the support box 7 close to the garment position are used to draw air downward to generate negative pressure suction to ensure the stability of the garment, and the equipment directly blocks the air through the wind shield 9 at the position corresponding to the suction hole 10, and uses the exhaust pipe 2 12 between the wind shields 9 to extract air to generate negative pressure, thereby avoiding direct extraction from the position corresponding to the suction hole 10, which may cause wrinkles on the garment at the position of the suction hole 10 and affect the screen printing effect;

[0040] In addition, by setting the width of the windshield 9 to gradually decrease from the middle to the sides, the distance between the two adjacent groups of exhaust pipes 12 is gradually reduced from the middle to the sides. Due to the change in distance, the corresponding exhaust intensity above the windshield 9 gradually increases from the middle to the sides. By setting the exhaust pipe 11 in the middle position, the air flow in the middle area below the windshield 9 is gathered to the middle; thereby, negative pressure suction is used to ensure the stability of the clothing, and when the screen printing mechanism 2 is quickly pressed down to print, an offset force is generated from above, and the clothing is smoothed by the gradual change of the exhaust intensity at different positions below, so as to quickly offset the offset force and ensure the flatness of the clothing, thereby improving the actual screen printing operation effect.

[0041] Reference Figure 3 The top of the conveyor belt 3 is flush with the top of the base 1, and the support box 7 is arranged in the mounting groove 101. The top of the support box 7 is slidably connected to the conveyor belt 3. In actual use, the conveyor belt 3 is rotated step by step by the driving mechanism 6 to continuously send the garment to be printed to the bottom of the screen printing mechanism 2 and the top of the support box 7. Negative pressure is used to pump air to stabilize the garment and lower the screen printing mechanism 2 for screen printing. The gradual change of the airflow under the conveyor belt 3 is used to ensure the flatness of the garment when the screen printing mechanism 2 is quickly lowered, and the air pressure below is restored after the screen printing is completed to send the garment out, so as to achieve continuous and efficient processing.

[0042] Example 2

[0043] Example 2 includes all the structures and methods of Example 1, refer to Figure 1-Figure 2A clothing screen printing device also includes: horizontally placed movable guide rails 15 are provided on both sides above the base 1, and the movable guide rails 15 extend along the directions of both ends. The extending direction of the movable guide rails 15 is the same as that of the wind shield 9. The bottom of the movable guide rail 15 is connected to a fixed plate 16 facing the side direction, and a horizontally placed blowing pipe 17 is fixed between two adjacent fixed plates 16. One end of the blowing pipe 17 is connected to a connecting air pipe 20, and the connecting air pipe 20 is made of a hose material. The end of the connecting air pipe 20 away from the blowing pipe 17 extends upward, and the end of the connecting air pipe 20 away from the blowing pipe 17 is connected to a hair dryer. Figure 9 , the bottom of the blowing pipe 17 is provided with air holes 18 distributed at equal distances in the middle position along the axial direction, and the bottom of the blowing pipe 17 is provided with air holes 19 on both sides of the air hole 18. In actual use, after the clothing is moved to the screen printing station, the lower support box 7 starts to pump air downward, and the moving guide rail 15 is used to make the blowing pipe 17 move quickly from one end to the other end, while blowing air downward from the bottom end of the blowing pipe 17 above the clothing. On the one hand, the air extraction from the bottom and the blowing from the top are combined to expel the air gap with the bottom of the clothing to ensure the stability of the clothing adsorption;

[0044] On the other hand, the clothes are smoothed by the wind hole 18 that blows air vertically downward and the wind hole 2 19 that blows air obliquely to the two ends, and the bottom gradual airflow is combined with the bottom gradual airflow to smoothen the clothes. In the process of gradually weakening airflow, the screen printing mechanism 2 descends to offset the offset force caused by the rapid descent, thereby improving the stability and flatness of the clothes during the continuous screen printing operation, thereby improving the actual screen printing operation effect.

[0045] Reference Figure 2-Figure 3 The present invention provides that hot air is blown into the blowing pipe 17, the hair dryer is configured as a hot air blower, a circulation cavity with openings at both ends is provided in the middle position of the wind shield 9, both ends of the circulation cavity are connected to a cold air pipe 13 provided through the partition 8, the circulation cavity is connected to the circulation fan and the refrigeration mechanism through the cold air pipes 13 at both ends, and cold air circulates in the circulation cavity, the wind shield 9 is made of heat exchange material, and in the actual process of continuous screen printing, the circulation cavity in the wind shield 9 maintains the circulation of cold air and continuously cools down the support box 7 and the lower position of the clothing, and when the clothing is screen printed, hot air is blown downward from the bottom of the movable blowing pipe 17 to smooth it, thereby generating a relative temperature difference between the upper and lower parts of the clothing; and the downward airflow movement effect is increased due to the temperature difference between the upper and lower positions in the clothing, so as to reduce the influence of the upward rebound squeezing airflow generated when the screen printing mechanism 2 is quickly lowered on the clothing, thereby further ensuring the flatness and stability of the clothing during the screen printing operation, and further improving the actual screen printing effect.

[0046] Reference Figure 8The heat exchange fins 14 are arranged at the top and bottom of the windshield 9, and the heat exchange fins 14 are arranged at the top and bottom of the windshield 9. The heat exchange fins 14 are arranged at the top and bottom of the windshield 9. The heat exchange fins 14 are arranged at the top and bottom of the windshield 9. The heat exchange fins 14 are arranged at equal distances along the two end directions. The heat exchange fins 14 face the side positions. In actual use, the heat exchange fins 14 distributed at intervals are used to increase the heat exchange effect between the inside and outside of the circulation cavity. The heat exchange fins 14 are facing the side and distributed. When the exhaust pipe 12 guides the airflow downward, the airflow at the top of the windshield 9 flows from the middle to the two sides, and is partially blocked by the distributed heat exchange fins 14 to reduce the strong flow at the position of the suction hole 10. The suction airflow at intervals hits the heat exchange fins 14, thereby increasing the vibration effect of the heat exchange fins 14 to improve the internal and external heat exchange effect, thereby further improving the actual operation effect to improve the screen printing effect on clothing.

[0047] Reference Figure 10-11 In the present invention, a dispersion piece 21 is provided on both sides of the axis of the blowing pipe 17. The dispersion piece 21 is arranged parallel to the axis direction of the blowing pipe 17. The dispersion piece 21 is arranged between the air hole 18 and the air hole 2 19. The top of the blowing pipe 17 is detachably connected to an auxiliary plate 1701. A fixing block 22 is fixed between the top of the dispersion piece 21 and the auxiliary plate 1701 to facilitate the disassembly, replacement and cleaning of the dispersion piece 21. The dispersion piece 21 is made of a spring material. An extrusion air cavity is opened in the dispersion piece 21. A plurality of bulges 23 are provided on both sides of the dispersion piece 21. The bulges 23 are made of silicone material. In actual use, the blowing pipe 17 is connected from the position close to the air pipe 20. Hot air is injected at one end, and when air flow difference occurs at the two end positions of the blowing pipe 17 due to temperature difference, or when the blowing pipe 17 has different internal air flow differences due to rebound air flow difference caused by different air outlet positions at the air holes due to different distances between the bottom end and the clothing, the air flow at the extrusion position is squeezed inwardly to the bulge 23 and the position of the dispersion member 21 at the corresponding position, and the air flow inside the dispersion member 21 is diffused to other positions and opened outward to squeeze the air flow at the surrounding positions, thereby increasing the pressure difference and making the air flow quickly and evenly dispersed in the blowing pipe 17, and facilitating the blowing when adjusting according to the differences on the top of the clothing, thereby improving the flatness and stability of the actual clothing, and further improving the actual screen printing operation effect.

[0048] Example 3

[0049] Reference Figure 1 and Figure 12Based on Examples 1 and 2, a clothing screen printing device further includes: upwardly extending support frames 24 are fixed to the four corners of the top of the base 1, and lifting guide rails 25 are embedded in the sides of the support frames 24. The four lifting guide rails 25 are connected to the same horizontally placed top plate 26. The screen printing mechanism 2 is provided with a machine box 28 located below the top plate 26, and a lifting cylinder 27 is connected between the top of the machine box 28 and the top plate 26;

[0050] Reference Figure 1 A connecting slot 2601 is provided at the top of the top plate 26 corresponding to the support frame 24. The inner wall of the connecting slot 2601 is slidably connected to the outer wall of the support frame 24. A lifting block is detachably connected between the connecting slot 2601 and the lifting guide rail 25.

[0051] Reference Figure 13 , an inner cavity 2801 with openings on both sides is provided in the middle position of the machine box 28, and cover plates 2802 are detachably connected to both sides of the inner cavity 2801, and a through groove is provided in the middle area of ​​the bottom of the inner cavity 2801, in which a silk screen membrane 31 is fixed, and a scraper 34 is provided at a position corresponding to the silk screen membrane 31 in the inner cavity 2801, and the scraper 34 moves back and forth along the direction between the two ends of the base 1, and a grouting pipe 37 is provided at a position corresponding to the inner cavity 2801 and the silk screen membrane 31. In actual use, the lifting guide rail 25 is used to move the machine box 28 to adjust the initial position, so as to adjust the lowering height according to the actual environmental wind conditions and clothing quality; and in the process of screen printing, the lifting cylinder 27 is used to lower the machine box 28 and then move the scraper 34 to perform printing operations, and cooperate with the conveyor belt 3 and the exhaust operation below to ensure the continuous operation effect of silk screen printing on clothing.

[0052] Reference Figure 13 In the present invention, vertically arranged electric guide rails 32 are fixed at both ends of the inner cavity 2801, one end of the electric guide rail 32 is connected to a mounting plate 33, an electric push rod 35 is connected between the scraper 34 and one of the mounting plates 33, and a grouting pipe 37 is connected between the other end face of the scraper 34 and the mounting plate 33 at the corresponding position. The grouting pipe 37 is located between the scraper 34 and the mounting plate 33 and adopts a retractable hose. A limiting slide rod 36 is fixed between the two mounting plates 33, and sliding holes are opened at the corresponding positions of the scraper 34 and the limiting slide rod 36 to facilitate the adjustment of the downward pressure of the scraper 34 and ensure the uniformity of the silk screen printing by grouting to the middle position.

[0053] Reference Figure 13-14In the present invention, the bottom of the machine box 28 is provided with an upwardly concave groove 39 at both ends of the screen film 31. The concave groove 39 extends along the two sides. The bottom of the inner wall of the concave groove 39 is slidably connected with an extrusion bar 40. A spring 41 is connected between the top of the extrusion bar 40 and the concave groove 39. The bottom end of the extrusion bar 40 is provided with a magnetic adsorption sheet. The position corresponding to the extrusion bar 40 on the top of the support box 7 is embedded with an electromagnetic block 42. In fact, during continuous screen printing, the bottom of the machine box 28 is close to the clothing and has a moving area. The distance is greater than the height of the blowing pipe 17, and the bottom end of the extrusion bar 40 is also above the blowing pipe 17. After the clothing reaches the position, Air is extracted from under the garment to generate a gradient airflow negative pressure to maintain the garment's stability. The blow pipe 17 moves from one end to the other to blow air to smooth and ensure the garment's flatness. After the blow pipe 17 passes a squeeze bar 40, the electromagnetic block 42 at the corresponding position is energized to attract the corresponding squeeze bar 40 downward. At this time, there is still a gap between the bottom end of the squeeze bar 40 and the garment, but no direct contact is made. After both electromagnetic blocks 42 are energized and the blow pipe 17 moves to the other end, the machine box 28 is lowered. At this time, the squeeze bars 40 at both ends increase their magnetic attraction when approaching the electromagnetic block 42, and quickly descend from the end to press the garment. Then, the bottom of the machine box 28 is lowered to press the garment flat.

[0054] Therefore, after the clothes are in place, the blowing tube 17 moves quickly, and the two electromagnetic blocks 42 are energized quickly and in sequence, so that the extrusion bars 40 at the two ends successively press down the clothes in a variable speed manner, thereby avoiding the deviation of wrinkles at the extrusion position, and ensuring the flatness of the clothes at the middle position corresponding to the screen film 31 through the variable speed downward pressure at both ends, thereby cooperating with the airflow below to improve the actual overall screen printing operation effect.

[0055] Reference Figure 15 In the present invention, dispersion holes 45 are provided at both ends of the bottom of the extrusion bar 40 at equal distances, and the top ends of the dispersion holes 45 penetrate from the end face of the extrusion bar 40. The top of the extrusion bar 40 is provided with connecting holes 43 at equal distances, and the bottom ends of the connecting holes 43 are provided with extension holes 44 extending and penetrating to the two end faces of the extrusion bar 40. In fact, when the extrusion bar 40 descends, the extruded airflow pressed down by the middle position of the bottom end of the extrusion bar 40 is dispersed upward from the dispersion holes 45 and from the end face to offset the extruded airflow from the outside to the inside and avoid wrinkles on the clothes. When the extrusion bar 40 descends, the air cavity above it increases, and the connecting holes 43 are filled with air from the extension holes 44 at both ends and out from above the connecting holes 43. In combination with the dispersion holes 45, the airflow around the extrusion bar 40 is relatively stable, and the direct extruded airflow movement during rapid descent can be avoided, thereby further enhancing the actual effect of continuous screen printing on clothes.

[0056] Example 4

[0057] Based on Example 3, a clothing screen printing device is provided, wherein the moving distance of the blowing pipe 17 is greater than the width between the ends of the machine box 28, so that the machine box 28 does not contact the blowing pipe 17 when it is lowered, thereby ensuring effective movement of the device.

[0058] Example 5

[0059] Reference Figure 1 On the basis of Example 3, a clothing screen printing device is provided, in which the moving distance of the blowing pipe 17 is less than the width between the ends of the machine box 28, and embedding grooves 38 are provided at both ends of the bottom of the machine box 28. The embedding grooves 38 extend along the two side directions, and the two sides of the embedding grooves 38 are penetrated. The distance between the two embedding grooves 38 is greater than the distance between the two recessed grooves 39, so that the blowing pipe 17 moves between the two embedding grooves 38. When the machine box 28 is lowered for screen printing, the stationary blowing pipe 17 just extends into the embedding groove 38 at the bottom of the machine box 28, ensuring the effective movement of the equipment while reducing the overall width of the equipment in the end face direction compared to the comparative document 4.

[0060] Example 6
