Description

Technical Field

[0001] The invention relates to the technical field of clothing production and processing, and in particular to a full-automatic pre-processing atomizing spray machine. Background Art

[0002] Garment spraying is to spray ink on garments to form a specific pattern, making the garment more personalized. Before spraying garments, a layer of pre-treatment liquid needs to be sprayed on the surface of the garment in advance. The purpose of spraying the pre-treatment liquid is to prevent the ink from penetrating and spreading, which is conducive to the formation of the pattern.

[0003] The existing pre-treatment liquid spraying process mainly relies on manual hand-held spraying guns for spraying, and the spraying guns rely on air compressors to provide liquid delivery power, thereby generating mobile hydraulic pressure, which is convenient for effectively spraying the pre-treatment liquid onto the clothing fabric.

[0004] The disadvantages of the existing technical solutions are that: when spraying the pre-treatment liquid, the manual hand-held spraying pot is not convenient enough, the spraying effect is poor and the efficiency is low. Although there are also automated spraying equipment for spraying, such as the pre-treatment liquid spraying equipment and pre-treatment liquid spraying method for the direct spraying process of the ready-made coating with the authorization announcement number CN114836916B, the support frame, the spray trolley and the table are provided, the support frame is provided with a Y-axis slide rail, the spray trolley is driven by the Y-axis moving drive mechanism to move on the Y-axis slide rail, the support frame is provided with a Y-axis slide rail, the table is provided with an X-axis slide rail, and the table is provided with an X-axis slide rail. The mobile driving mechanism drives the movement on the X-axis slide rail, that is, the above-mentioned public scheme can realize automatic control of spraying, but when the spray pipeline is blocked, although it can be repaired, there must be pre-treatment liquid in the pipeline when it is blocked, and the pipeline needs to be disassembled to clear the pipeline, which can easily cause liquid leakage, causing pollution of surrounding equipment and waste of liquid, and after the maintenance is completed, the leaked and wasted liquid needs to be replenished, resulting in inconvenient operation; and the existing spraying equipment is generally directly connected to the liquid storage tank through an air compressor to directly transport liquid, which is not convenient for controlling the spraying amount and affects the spraying effect. Summary of the invention

[0012] As a further solution of the present invention: the automatic liquid return alarm mechanism also includes a hydraulic sensor, a lifting drive mechanism and an alarm, the hydraulic sensor is used to detect the hydraulic pressure in the main pipe head; the lifting drive mechanism is arranged at the bottom of the steering box, and the lifting drive mechanism is electrically connected to the hydraulic sensor, and a start button switch aligned with the lifting drive mechanism is installed at the bottom of the support plate, and the start button switch is electrically connected to the alarm.

[0013] As a further solution of the present invention: the lifting drive mechanism includes a driving motor, a driving gear and a rack. The driving motor is fixedly mounted on the bottom of the steering box, and the driving motor is electrically connected to the hydraulic sensor. The driving gear is fixedly mounted on the main shaft end of the driving motor. A connecting guide rail is fixedly connected to one side of the bottom of the steering box.

[0016] Beneficial effects of the present invention: When the liquid spraying pipeline of the present invention is blocked, the accumulated rising pressure in the pipeline will act on the provided blocking slider, causing the blocking slider to slide along the second connecting pipe head.

[0018] The present invention first uses a peristaltic pump to transport the pretreatment liquid to a quantitative transition tank, and then uses a negative pressure suction pump to suck a fixed amount of pretreatment liquid in the quantitative transition tank for spraying, thereby avoiding excessive or insufficient spraying liquid, and also avoiding uneven spraying due to uncontrollable pressure.

[0019] The present invention realizes automatic mobile spraying by the spray gun relying on the first electric guide rail and the second driving electric guide rail, which can ensure the spraying quality, and after the liquid enters the quantitative transition tank, it can also automatically trigger the negative pressure suction pump to deliver the liquid, reducing the impact of manual operation.

[0020] The pre-treatment liquid sprayed by the spray gun of the present invention is in an atomized state, and has a brighter coverage than the traditional one, a stronger fabric penetration ability, a stronger adsorption force for subsequent digital printing colors, and improved color fastness.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 12 As shown, the fully automatic pre-treatment atomizing spray machine is used to spray the pre-treatment liquid before printing ink patterns on clothes to prevent the ink from penetrating and spreading. The spray machine specifically includes a frame body 1, a spray platform 11 and a spray gun 10 arranged on the spray platform 11. When spraying the pre-treatment liquid, the clothes are laid on the spray platform 11, and then the pre-treatment liquid is sprayed onto the clothes by the spray gun 10; the spray machine also includes a pre-treatment liquid conveying mechanism and an automatic liquid return alarm mechanism; The pretreatment liquid delivery mechanism includes a quantitative transition tank 9 and a suction negative pressure pump 19. The liquid outlet end of the suction negative pressure pump 19 is connected to the spray gun 10, and the two can be connected by a metal corrugated hose to avoid the pipeline being stretched due to excessive internal pressure when blocked. The quantitative transition tank 9 is arranged at the liquid inlet end of the suction negative pressure pump 19, and the suction negative pressure pump 19 is fixedly installed on the frame body 1. The suction negative pressure pump 19 can suck the pretreatment liquid stored in the quantitative transition tank 9 to the spray gun 10 for spraying. The quantitative transition tank 9 is used to make the pretreatment liquid sprayed by the spray gun 10 each time a fixed amount; It should be noted that a one-way valve is installed between the quantitative transition tank 9 and the suction negative pressure pump 19 to ensure that the liquid can only flow from the quantitative transition tank 9 to the suction negative pressure pump 19. In addition, a liquid level sensor is installed in the quantitative transition tank 9, and when the liquid level reaches the set value, the suction negative pressure pump 19 is operated.

[0026] The automatic liquid return alarm mechanism is arranged between the liquid outlet end of the suction negative pressure pump 19 and the liquid inlet end of the quantitative transition tank 9. When the spray gun 10 is blocked, the automatic liquid return alarm mechanism sucks the pretreatment liquid in the pipeline between the suction negative pressure pump 19 and the spray gun 10 back into the quantitative transition tank 9 and sounds an alarm, so as to remind the staff that the current spray gun 10 is blocked and cannot work normally and needs maintenance. At the same time, the pretreatment liquid that has entered the pipeline between the suction negative pressure pump 19 and the spray gun 10 is also drawn back to avoid pollution caused by large-scale liquid leakage when the pipeline is disassembled. At the same time, when the spraying operation is carried out after the maintenance is completed, there is no need to replenish the quantitative transition tank 9 with liquid, and work can be continued directly.

[0027] In some specific embodiments, such as Figure 3 and Figure 4 As shown, the pretreatment liquid delivery mechanism also includes a pretreatment liquid storage box 7 and a delivery pump 8. The pretreatment liquid storage box 7 can be directly placed on one side of the frame body 1. The delivery pump 8 is a peristaltic pump, and its liquid inlet end is connected with the pretreatment liquid storage box 7 through a tube body, and the liquid outlet end is connected with the liquid inlet end of the quantitative transition tank 9 through a pipeline. It should be noted that the bottom of the quantitative transition tank 9 can be used as the liquid inlet end and the top as the liquid outlet end. The pretreatment liquid in the pretreatment liquid storage box 7 is sucked by the delivery pump 8 and delivered to the quantitative transition tank 9. When the set amount is reached, the suction negative pressure pump 19 is started to perform the spraying operation.

[0028] In some specific embodiments, in combination Figure 4 and Figure 5 As shown, the automatic liquid return alarm mechanism includes a liquid return suction pump 16, a main pipe head 18 and a steering box 17. The main pipe head 18 is fixedly connected to the liquid outlet end of the suction negative pressure pump 19, and the main pipe head 18 is connected to the spray gun 10 through a metal corrugated hose. The steering box 17 is arranged on one side of the main pipe head 18, and an elastic sealing mechanism is arranged between the steering box 17 and the main pipe head 18; the side of the steering box 17 away from the main pipe head 18 is connected to a first connecting pipe head 21 connected to the liquid inlet end of the liquid return suction pump 16, and the liquid return suction pump 16 is fixedly installed on the frame body 1, and the liquid outlet end of the liquid return suction pump 16 is connected to the liquid inlet end of the quantitative transition tank 9 through a pipeline.

[0029] Among them, combined Figure 7 and Figure 8As shown, the elastic blocking mechanism includes a second connecting pipe head 20, a blocking slider 26, a supporting plate 28 and a connecting spring 31. The second connecting pipe head 20 is fixedly connected between the steering box 17 and the main pipe head 18, and the second connecting pipe head 20 communicates with the steering box 17 and the main pipe head 18. The blocking slider 26 is slidably connected in the second connecting pipe head 20. The blocking slider 26 is in the second connecting pipe head 20, which can isolate the second connecting pipe head 20. A rubber ring can be set on the outer ring of the blocking slider 26 to ensure sealing; the supporting plate 28 is slidably connected in the steering box 17, and the supporting plate 28 is connected to the steering box 17. A connecting plate 29 is fixedly connected to one side of the support plate 28, and the connecting plate 29 is connected to the blocking slider 26 by a connecting spring 31. It should be noted that when the blocking slider 26 slides in the second connecting pipe head 20, the support support plate 28 is suspended in the steering box 17 and does not touch the bottom. Limit blocks 32 are fixedly provided on both sides of the bottom of the steering box 17, and a pressure sensing switch 33 electrically connected to the starting circuit of the return liquid suction pump 16 is fixedly installed on the limit block 32 on one side, and a stop button switch electrically connected to the stop control circuit of the suction negative pressure pump 19 is fixedly installed on the limit block 32 on the other side.

[0030] It should be noted that when the pressure sensing switch 33 is pressurized, the liquid return suction pump 16 is started, and when there is no pressure, the liquid return suction pump 16 is stopped.

[0031] It should be noted that the connecting spring 31 can overcome the liquid pressure generated by the suction negative pressure pump 19 when normally delivering liquid, and will not be deformed; When the spray gun 10 stops spraying liquid, but the suction negative pressure pump 19 is still delivering liquid, it means that the pipeline for delivering liquid is blocked at this time, and as the suction negative pressure pump 19 continues to deliver liquid, the hydraulic pressure in the pipeline continues to rise, and the rising hydraulic pressure exceeds the safe value range, thereby pushing the blocking slider 26 to slide along the second connecting pipe head 20 toward the direction of the steering box 17, and compressing the connecting spring 31. During this process, if the blockage in the pipeline is automatically unblocked by relying on the accumulated rising hydraulic pressure, the blocking slider 26 can be automatically reset by relying on the connecting spring 31. If automatic unblocking cannot be achieved, the blocking slider 26 will finally slide into the steering box 17, and at the moment of completely detaching from the second connecting pipe head 20, it will fall along the steering box 17 with the supporting plate 28 by relying on its own weight. For details, please refer to Figures 9 and 10In this way, the first connecting pipe head 21, the steering box 17 and the second connecting pipe head 20 are connected, and the falling support plate 28 presses on the limit block 32, which produces a squeezing effect on the pressure sensing switch 33 and the stop button switch. The pressure sensing switch 33 starts the return liquid suction pump 16 to generate a negative pressure effect. At the same time, the stop button switch feeds back a signal, relies on the matching controller to receive the signal, and sends an instruction to control the suction negative pressure pump 19 to stop. In this way, the return liquid suction pump 16 can rely on the negative pressure effect to suck the pretreatment liquid in the pipeline between the suction negative pressure pump 19 and the spray gun 10 back into the quantitative transition tank 9.

[0032] It should be noted that in order to facilitate the support plate 28 to slide down along the steering box 17, the bottom of the steering box 17 is opened, and in order to prevent liquid from leaking from the edge of the support plate 28, a sealing ring is installed on the edge of the support plate 28, and in order to ensure that the support plate 28 slides down, the blocking slider 26 can have an applicable larger weight, so as to facilitate sliding down by relying on weight to overcome friction resistance.

[0033] In some specific embodiments, in order to facilitate the smooth lateral sliding of the blocking slider 26 relative to the supporting plate 28, a telescopic connecting rod 30 is fixedly connected between the blocking slider 26 and the connecting plate 29. The telescopic connecting rod 30 is telescopic and distributed axially along the second connecting pipe head 20, thereby facilitating the smooth lateral sliding of the blocking slider 26.

[0034] In some specific embodiments, such as Figure 8 As shown, a plurality of mounting grooves 34 are evenly distributed on the end of the blocking slider 26 facing the main pipe head 18, and a ball 35 is movably fitted in each mounting groove 34. The groove width of the mounting groove 34 is smaller than the diameter of the ball 35, so that the ball 35 can be prevented from falling out. An elastic ball 36 is also arranged between the ball 35 and the mounting groove 34. When the elastic ball 36 is in a normal state, a part of the ball 35 is exposed outside the mounting groove 34.

[0035] like Fig.12As shown, when the blocking slider 26 slides away from the second connecting pipe head 20 and falls to the bottom of the steering box 17 by gravity, the blocking slider 26 starts to fall at the moment when the end of the blocking slider 26 is separated from the second connecting pipe head 20. At this time, although the ball 35 is in a convex state, it can be squeezed with the edge of the second connecting pipe head 20 in contact, and the ball 35 is squeezed into the installation groove 34 to flatten the elastic ball 36, that is, the ball 35 can be stored to a certain extent, and the connecting spring 31 can also be further compressed, so that the blocking slider 26 can be slightly away from the second connecting pipe head 20, thereby avoiding hindering the blocking slider 26 from falling. During the falling process of the blocking slider 26, due to the rebound force of the connecting spring 31, its end relies on the ball 35 to resist the inner wall of the steering box 17, so that it is easy to fall along the inner wall of the steering box 17, thereby avoiding the end of the blocking slider 26 being pressed against the inner wall of the steering box 17 due to the rebound force of the connecting spring 31 and unable to fall.

[0036] In some specific embodiments, in combination Figure 5 and Figure 6 As shown, the automatic liquid return alarm mechanism also includes a hydraulic sensor 27, a lifting drive mechanism and an alarm. The hydraulic sensor 27 is installed on the main pipe head 18 to detect the hydraulic pressure in the main pipe head 18; the lifting drive mechanism is arranged at the bottom of the steering box 17, and the lifting drive mechanism is electrically connected to the hydraulic sensor 27. A start button switch 37 aligned with the lifting drive mechanism is installed at the bottom of the support plate 28, and the start button switch 37 is electrically connected to the alarm. The alarm can be fixedly installed on the outer wall of the steering box 17.

[0037] After the liquid return suction pump 16 has sucked out all the liquid in the pipeline, the hydraulic sensor 27 detects that the hydraulic pressure in the main pipe head 18 is lower than the set value, and then the lifting drive mechanism starts to rise, thereby pushing the support plate 28 to rise with the blocking slider 26. When the blocking slider 26 rises to a position aligned with the second connecting pipe head 20, it can rely on the rebound force of the connecting spring 31 to reset and slide into the second connecting pipe head 20. At the same time, the lifting drive mechanism also contacts the start button switch 37, and the start button switch 37 activates the alarm to sound an alarm, so as to remind the staff that the pipeline needs to be repaired after the liquid return is completed, so as to avoid the staff not knowing when the liquid return is completed and repairing it in advance, resulting in liquid leakage.

[0038] In some specific embodiments, the lifting drive mechanism includes a driving motor 25, a driving gear 24 and a rack 22. The driving motor 25 is fixedly mounted at the bottom of the steering box 17, and the driving motor 25 is electrically connected to the hydraulic sensor 27. The driving gear 24 is fixedly mounted on the main shaft end of the driving motor 25. A connecting guide rail 23 is fixedly connected to one side of the bottom of the steering box 17. The rack 22 is slidably connected to the connecting guide rail 23, and the rack 22 is meshed with the driving gear 24. When the driving motor 25 is started, it drives the driving gear 24 to rotate, and the driving gear 24 drives the rack 22 to move upward to push the support plate 28 and squeeze it onto the start button switch 37.

[0039] In some specific embodiments, in combination Figure 1 and Figure 2 As shown, in order to prevent the spraying liquid from spreading to the surrounding environment and causing pollution, a cover body 2 is provided on the spray station 11, one side of the cover body 2 is movably connected to the frame body 1 through a hinge, a suspension 3 is fixedly connected to the frame body 1, a hydraulic telescopic rod 5 is fixedly connected to the bottom of the suspension 3, a fixed pulley 4 is installed on the top of the suspension 3, a traction wire 6 is connected between the telescopic end of the hydraulic telescopic rod 5 and the cover body 2, and the traction wire 6 bypasses the fixed pulley 4, when it is necessary to take or put down clothes, the hydraulic telescopic rod 5 is controlled to be extended and retracted, so that the cover body 2 is pulled or lowered by the traction wire 6, and the side of the cover body 2 close to the frame body 1 is an opening, and a long strip opening 12 is opened on the frame body 1, and a cloth curtain 13 is distributed in the long strip opening 12, so that the spray gun 10 can pass into the cover body 2 for spraying operation.

[0040] In some specific embodiments, a first electric guide rail 14 is fixedly installed on the other side of the spray station 11, and a second electric guide rail 15 is slidably arranged on the first electric guide rail 14. The spray gun 10 is slidably connected to the second electric guide rail 15. The first electric guide rail 14 and the second electric guide rail 15 are vertically distributed, corresponding to the X-axis and Y-axis directions respectively, that is, the spray gun 10 can move in the Y-axis direction along the second electric guide rail 15, and then can also rely on the second electric guide rail 15 to slide along the first electric guide rail 14 to move in the X-axis direction. The movements in the two directions are controlled by a program, thereby realizing the automatic movement and spraying of the spray gun 10.

[0041] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios: First, the cover body 2 is opened, and then the clothes are placed on the spray table 11, and then the cover body 2 is closed. Then, the pretreatment liquid in the pretreatment liquid storage box 7 is sucked by the delivery pump 8, and delivered to the quantitative transition tank 9. When the set amount is reached, the suction negative pressure pump 19 starts to suck the pretreatment liquid in the quantitative transition tank 9 and delivers it to the spray gun 10 for spraying. The spray gun 10 is controlled by a computer to move along the second electric guide rail 15 and the first electric guide rail 14 in the X-axis and Y-axis directions to spray a fixed area.

[0042] When the spray gun 10 stops spraying liquid, but the suction negative pressure pump 19 is still delivering liquid, it means that the pipeline for delivering liquid is blocked at this time, and as the suction negative pressure pump 19 continues to deliver liquid, the hydraulic pressure in the pipeline continues to rise, and the rising hydraulic pressure exceeds the safe value range, thereby pushing the blocking slider 26 to slide along the second connecting pipe head 20 toward the direction of the steering box 17, and compressing the connecting spring 31. During this process, if the blockage in the pipeline is automatically unblocked by relying on the accumulated rising hydraulic pressure, the blocking slider 26 can be automatically reset by relying on the connecting spring 31. If automatic unblocking cannot be achieved, the blocking slider 26 will finally slide into the steering box 17 and completely detach from the second connecting pipe head 20 at the moment. The supporting plate 28 falls along the steering box 17 by its own weight, so that the first connecting pipe head 21, the steering box 17 and the second connecting pipe head 20 are connected, and the falling supporting plate 28 presses on the limit stopper 32, exerts a squeezing effect on the pressure sensing switch 33 and the stop button switch, and the pressure sensing switch 33 starts the liquid return suction pump 16 to generate a negative pressure effect, and the stop button switch feeds back a signal, relies on the matching controller to receive the signal, and sends a command to control the suction negative pressure pump 19 to stop, so that the liquid return suction pump 16 can rely on the negative pressure effect to suck the pre-treatment liquid in the pipeline between the suction negative pressure pump 19 and the spray gun 10 back into the quantitative transition tank 9; The blocking slider 26 slides away from the second connecting pipe head 20 and falls to the bottom of the steering box 17 by gravity. At the moment when the end of the blocking slider 26 is separated from the second connecting pipe head 20, the blocking slider 26 begins to fall. At this time, although the ball 35 is in a raised state, it can be squeezed with the edge of the second connecting pipe head 20 in contact, and the ball 35 is squeezed into the installation groove 34 to flatten the elastic ball 36, that is, the ball 35 can be stored to a certain extent, and the connecting spring 31 can also be further compressed, so that the blocking slider 26 can be slightly away from the second connecting pipe head 20, thereby avoiding hindering the blocking slider 26 from falling. In the process of the blocking slider 26 falling, due to the rebound force of the connecting spring 31, its end relies on the ball 35 to resist the inner wall of the steering box 17, so that it is easy to fall along the inner wall of the steering box 17, thereby avoiding the end of the blocking slider 26 being pressed against the inner wall of the steering box 17 due to the rebound force of the connecting spring 31 and unable to fall.

[0043] After the liquid return suction pump 16 has sucked out all the liquid in the pipeline, the hydraulic sensor 27 detects that the hydraulic pressure in the main pipe head 18 is lower than the set value, and then the lifting drive mechanism starts to rise, thereby pushing the support support plate 28 to lift the blocking slider 26. When the blocking slider 26 rises to a position aligned with the second connecting pipe head 20, it can rely on the rebound force of the connecting spring 31 to reset and slide into the second connecting pipe head 20. At the same time, the lifting drive mechanism also contacts the start button switch 37, and the start button switch 37 activates the alarm to sound an alarm, so as to remind the staff that the pipeline needs to be repaired after the liquid return is completed, so as to avoid the staff not knowing when the liquid return is completed and repairing it in advance. At the same time, since the pre-treatment liquid in the pipeline is drawn back into the quantitative transition tank 9, a large amount of liquid leakage and pollution can be avoided when the pipeline is disassembled. At the same time, when the spraying operation is performed after the maintenance is completed, there is no need to replenish the quantitative transition tank 9 with liquid, and work can be continued directly.

[0044] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
