Description

Technical Field

[0001] This utility model relates to the field of monkey machine technology, specifically to a spray control handle used during the drag teaching of a monkey machine. Background Technology

[0002] To meet customers' demands for aesthetics and individuality in jeans, a process called "monkey spraying" is often used during the jeans manufacturing process. Monkey spraying is a garment washing process that mainly uses liquids such as potassium permanganate solution on the jeans to cause the original color of the jeans to fade in certain areas according to the design requirements.

[0003] Regarding spray guns, authorization announcement number CN108435451B discloses an automatic spray gun, which specifically discloses a gun body, a horizontal through-tube in the center of the gun body, a nozzle assembly at the front end of the gun body, and a spray pattern air passage and an atomizing air passage on the nozzle assembly; a flow divider cover is installed between the nozzle assembly and the front end of the gun body, and an air outlet hole communicating with the spray pattern air passage is opened on the circular surface of the flow divider cover; the hollow part of the flow divider cover corresponds to the position of the horizontal through-tube; a paint control assembly is installed at the rear end of the gun body, and a ejector pin assembly controlled by the paint control assembly is installed on the horizontal through-tube; a piston chamber is formed between the ejector pin assembly and the rear end of the gun body, and the front end of the ejector pin assembly is inserted into the nozzle assembly; a paint inlet pipe, a main air inlet pipe, and a spray pattern air inlet are provided on the outer wall of the gun body. The gun body includes a paint inlet pipe and an atomizing air inlet pipe. The paint inlet pipe is connected to the horizontal passage pipe. The main air inlet pipe has an opening at the rear end of the gun body and is connected to the piston chamber. The spray pattern air inlet pipe has an opening at the rear end of the gun body and is connected to the piston chamber. After passing through control knob I, the spray pattern air inlet pipe has an opening at the front end of the gun body on the back side of the air outlet. The atomizing air inlet pipe has an opening at the rear end of the gun body and is connected to the piston chamber. After passing through control knob II, the atomizing air inlet pipe has an opening at the front end of the horizontal passage pipe on one side and is connected to the atomizing air passage. The ejector pin assembly includes an ejector pin clamping member inserted into the horizontal passage pipe, an ejector pin inserted into the ejector pin clamping member, and an ejector pin clamping seat for fixing the ejector pin. The ejector pin clamping seat is located at the rear end of the gun body and closes the rear end of the gun body. The ejector pin moves horizontally in the horizontal passage pipe under the action of the ejector pin clamping seat. The paint control assembly includes a knob guide seat threaded to the rear end of the gun body, a knob pin mounted on the knob guide seat and cooperating with the ejector pin assembly, and an ejector pin spring installed between the ejector pin assembly and the knob pin.

[0004] To ensure the machine can accurately execute the monkey spraying operation along the preset path and to verify the rationality of the process parameters, a manual test spray is generally required when using the monkey spraying machine for the first time to perform the monkey spraying process on jeans. This test spray confirms the movement path of the spray gun during subsequent automated production. Manual test spraying allows operators to visually observe the spraying effect of the potassium permanganate solution. This manual verification process effectively avoids batch process defects caused by improper program settings and is a crucial step in ensuring product quality. During the manual test spraying stage, the operator manually controls the automatic spray gun to move along the preset path and spray the corresponding amount of potassium permanganate solution, while recording the optimal movement trajectory and dwell time. This data is input into the control center of gravity as the benchmark parameters for subsequent automated production, ensuring that every pair of jeans achieves a consistent monkey spraying effect. This process is called "drag teaching."

[0005] During the drag-and-drop teaching process using the aforementioned automatic spray gun, if the operator wants to adjust the flow rate of the sprayed liquid, it is often necessary to manually rotate the ejector pin assembly to control the liquid flow rate. However, this operation method is rather cumbersome. If the liquid flow rate needs to be changed frequently, the operator will have to frequently rotate the ejector pin assembly with their other hand during the drag-and-drop teaching process, which is not only inconvenient but may also affect the teaching quality of the "drag-and-drop teaching".

[0006] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a spray control handle for use during the drag teaching of a monkey sprayer. This handle allows the operator to hold and move the main body of the handle by hand, and the operator can adjust the flow rate of the sprayed liquid by pressing and releasing the pressing part on the main body of the handle.

[0031] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0032] like Figures 1-3 As shown, a spray control handle is used during the drag teaching of a monkey machine. The spray control handle used during the drag teaching of the monkey machine is used to cooperate with the automatic spray gun of the monkey machine to control the automatic spray gun of the monkey machine to achieve flow rate adjustment.

[0033] like Figures 1-3As shown, the spray control handle used during the teaching of the monkey machine includes a handle body 1 with an internal mounting cavity 101, an encoder 2, a pressing member 3, an elastic reset member 4, and a sensor 5; the encoder 2 is installed in the mounting cavity 101 and its rotating shaft 21 extends horizontally; the upper end of the pressing member 3 is connected to the rotating shaft 21 of the encoder 2, and the lower end extends outward through a through hole 102 on the side wall of the handle body 1; the elastic reset member 4 is installed in the mounting cavity 101 and is used for the outward reset of the lower end of the pressing member 3; the sensor 5 is installed in the mounting cavity 101 and is used to cooperate with the pressing member 3. Furthermore, when using the spray control handle, during the pressing and releasing of the lower end of the pressing element 3, the pressing element 3 drives the rotating shaft 21 of the encoder 2 to rotate, causing the encoder 2 to generate corresponding pulse data through the rotation distance of its shaft 21. Simultaneously, during the movement of the pressing element 3, it is sensed by the sensor 5, indicating that the equipment has been activated and the pulse data is sent to the control center (not shown in the figure). The control center then sends an electrical signal based on the received pulse data and controls the automatic spray gun of the sprayer to adjust the liquid flow rate (i.e., adjust the spray volume) accordingly. The greater the rotation distance of the encoder shaft 21 driven by the pressing element 3, the greater the liquid flow rate of the automatic spray gun; the smaller the rotation distance of the encoder shaft 21 driven by the pressing element 3, the smaller the liquid flow rate of the automatic spray gun. Therefore, both the encoder 2 and the sensor 5 are electrically connected to the control center.

[0034] like Figure 3 As shown, in a preferred embodiment, the elastic reset member 4 is a torsion spring; the middle part of the elastic reset member 4 is sleeved on the rotating shaft 21 of the encoder 2, the first end of the elastic reset member 4 is fixedly set, and the second end is connected to the upper end of the pressing member 3. Therefore, after the torsion spring is set, when the lower end of the pressing member 3 is pressed, the second end of the torsion spring will be pulled accordingly. Then, when the pressing member 3 is released, the reset extension force of the torsion spring can be used to drive the pressing member 3 to reset.

[0035] like Figures 2-3 As shown, in order to facilitate the limiting of the first end of the elastic reset member 4, a horizontally extending stop post 6 is fixedly provided in the mounting cavity 101; the first end of the elastic reset member 4 is connected to the stop post 6, so that the stop post 6 can be used to limit and position the first end of the elastic reset member 4.

[0036] like Figures 2-3 As shown, in this embodiment, a mounting block 7 is fixed on the encoder 2; the mounting block 7 is fixed to the inner wall of the mounting cavity 101 by a connecting post 8; the stop post 6 is installed on the mounting block 7. The above arrangement makes it easy to install the stop post 6.

[0037] like Figures 2-3As shown, in a preferred embodiment, a bearing 9 is also fixed in the mounting cavity 101; the outer end of the encoder 2's rotating shaft 21 is mounted in the inner ring of the bearing 9. Therefore, by setting the bearing 9, the stability of the encoder 2's rotating shaft 21 during rotation can be ensured, and it is not easy for it to become skewed.

[0038] like Figures 2-3 As shown, in this embodiment, the sensor 5 is mounted on the side wall of the mounting cavity 101 by a positioning block 10, so that the sensor 5 can be installed conveniently and stably.

[0039] In this embodiment, sensor 5 is a proximity switch. However, those skilled in the art should know that other sensing devices can be used for sensor 5, as long as they can be used to detect the pressing member 3. No further examples will be given here.

[0040] like Figures 1-3 As shown, in this embodiment, a limiting post 31 is provided on each of the inner sides of the lower end of the pressing member 3; the limiting post 31 is located in the mounting cavity 101; the maximum distance between the two limiting posts 31 is greater than the width of the through hole 102; a protrusion 33 is provided on each of the outer sides of the lower end of the pressing member 3; the protrusion 33 is located outside the handle body 1; the maximum distance between the two protrusions 33 is greater than the width of the through hole 102. Therefore, by providing two limiting posts 31 and two protrusions 33, the pressing member 3 can be prevented from coming out of the through hole 102 or completely entering the mounting cavity 101, that is, it can be ensured that the pressing member 3 can only enter and exit in the through hole 102, effectively ensuring the movement stroke of the pressing member 3 and preventing it from coming out of the preset stroke.

[0041] like Figure 1 As shown, a concave arc-shaped groove 32 is provided on the outer wall of the lower end of the pressing member 3, which facilitates user operation. During use, the user's fingers can be placed directly in the arc-shaped groove 32 before pressing, resulting in high comfort.

[0042] like Figure 1 As shown, in this embodiment, a rotary button 103 is also provided on the handle body 1. Since monkey knitting machines typically have a rotating mechanism (not shown) for driving the jeans to rotate 180° during the drag teaching process, the rotary button 103 is used in conjunction with this rotating mechanism via a control center. For example, pressing the rotary button 103 drives the rotating mechanism to rotate the jeans 180°, allowing the operator to easily drag and teach both sides of the jeans separately. Therefore, by providing the rotary button 103 on the handle body 1, the operator can greatly facilitate the rotation of the jeans, making it highly practical.

[0043] like Figure 4 and Figure 5As shown, the spray control handle used during the teaching of the monkey machine is generally used to adjust the flow rate of liquid sprayed by the automatic spray gun of the monkey machine.

[0044] Regarding how to adjust the flow rate, the structure of the automatic spray gun of the monkey sprayer will be introduced below:

[0045] like Figures 6-9 As shown, the automatic spray gun of the monkey machine includes a spray gun body 11 and a stepless flow rate adjustment device 12. The spray gun body 11 is connected to the top of the handle body 1 so that the automatic spray gun can be moved synchronously when the operator moves the handle body 1.

[0046] like Figures 6-9 As shown, specifically, the spray gun body 11 includes a gun body 111, a ejector pin 112, and a nozzle 113; the gun body 111 has a horizontal channel 1111 extending back and forth inside; the nozzle 113 is located at the front end of the gun body 111; the ejector pin 112 can be used to move back and forth in the horizontal channel 1111 in a matching manner and its back and forth movement can open or close the outlet of the nozzle 113.

[0047] like Figures 6-9 As shown, the stepless flow regulating device 21 includes a connecting seat 211, a piston 212, a lead screw motor 213, and a spring assembly; the connecting seat 211 is installed at the rear end of the gun body 111; a push chamber 1112 communicating with the rear end of the horizontal channel 1111 is provided at the rear end of the gun body 111, the piston 212 is movably matched and installed in the push chamber 1112, and the front end of the push chamber 1112 is connected to an air intake channel (not shown in the figure) located on the spray gun body 111. In addition, the inlet of the air intake channel... The end can be used to connect to an external air supply device; the rear end of the ejector pin 112 is movably inserted into the piston 212, and a stop block 1121 for abutting against the rear end face of the piston 212 is installed on the outer side of the rear end of the ejector pin 112; the body of the lead screw motor 213 is connected to the connecting seat 211, and the lead screw output shaft 2131 of the lead screw motor 213 is located behind the ejector pin 112 and can move back and forth to cooperate with the ejector pin 112; the spring assembly is installed on the connecting seat 211 and is used for the forward reset of the ejector pin 112 and the piston 212. The air supply device, the lead screw motor 213, and the encoder 2 are all used for electrical connection to the control center.

[0048] As can be seen, after the pressure chamber 1112 is filled with gas through the air intake channel, it can correspondingly push the piston 212 and the ejector pin 112 to move backward until they abut against the lead screw output shaft 2131. Since the lead screw motor 213 can control the lead screw output shaft 2131 to stop at any position during the backward movement, the nozzle 113 can form multiple orifices during the opening process, that is, there are multiple flow rate levels that can be adjusted to adjust the flow rate of the ejected liquid.

[0049] Of course, the spray gun body 11 may also have other structures, such as a liquid inlet channel for inputting liquid and an atomizing channel for using gas to blow the liquid out in a mist form in the nozzle 113, etc. However, since the structures of these parts are all prior art, and these structures are not related to the corresponding technical solutions proposed in this application to solve the technical problems, they will not be described in detail here.

[0050] like Figure 7 As shown, Figure 3 As shown, in this embodiment, a movable cavity 2111 is provided in the connecting seat 211; the lead screw output shaft 2131 of the lead screw motor 213 passes through the movable cavity 2111.

[0051] like Figures 6-9 As shown, in a preferred configuration, the spring assembly includes a first spring 214 and a second spring 215; a limiting cavity 1113 communicating with the pressing chamber 1112 is also provided at the rear end of the gun body 111; both the first spring 214 and the second spring 215 are located in the limiting cavity 1113; the first spring 214 and the second spring 215 are respectively sleeved on the front end of the lead screw output shaft 2131 of the lead screw motor 213 and the rear end of the ejector pin 112; the first end of the first spring 214 and the first end of the second spring 215 are both fixedly set, the second end of the first spring 214 abuts against the rear end face of the piston 212, and the second end of the second spring 215 abuts against the rear end face of the stop block 1121. Therefore, with the above configuration, the first spring 214 can be used to drive the piston 212 to return to its original position, while the second spring 215 can be used to drive the ejector pin 112 to return to its original position.

[0052] like Figures 6-9 As shown, in this embodiment, the first end of the first spring 214 and the first end of the second spring 215 are respectively connected to the connecting seat 211, so that the first end of the first spring 214 and the first end of the second spring 215 both form a positioning effect, which helps to use the second ends of the two to drive the piston 212 and the ejector pin 112 forward to reset.

[0053] Combination Figure 4 and Figure 5The following describes the working principle of the spray control handle of the monkey spraying machine when used in conjunction with the automatic spray gun, in order to better understand this utility model:

[0054] First, to open the nozzle 113 outlet, the user presses the pressing member 3 and moves it inward a certain distance. During this movement, the sensor 5 detects the pressing member 3, indicating that the device is activated. Simultaneously, the pressing member 3 drives the encoder 2's shaft 21 to rotate, causing the encoder 2 to generate corresponding pulse data based on the rotation distance of its shaft 21. This pulse data is transmitted to the control center, which then sends an electrical signal to the lead screw motor 213 based on the received pulse data. This causes the lead screw motor 213 to control the lead screw output shaft 2131 to move backward a corresponding distance. Simultaneously, the control center controls the air supply device to fill the pressure chamber 1112 with the corresponding gas, thereby pushing the piston 212 backward. The piston 212, using the stop block 1121, synchronously pushes the ejector pin 112 backward until the rear end face of the ejector pin 112 abuts against the lead screw output shaft 2131, thus the lead screw output shaft 2131 effectively blocks the ejector pin 112. As a result, at this point, the front end of the ejector pin 112 opens the outlet of the nozzle 113, that is, the outlet of the nozzle 113 is opened to a certain extent and the liquid is sprayed out accordingly. If the outlet of the nozzle 113 is to be opened even more, the pressing member 3 can be pressed inward. In this way, due to the change of pulse data, the control center controls the lead screw motor 213 to continue to drive the lead screw output shaft 2131 backward, and the gas supply device continues to drive the piston 212 and the ejector pin 112 to move backward until they abut against the lead screw output shaft 2131. That is, the more the pressing member 3 is pressed inward, the farther the ejector pin 112 moves backward, the larger the outlet of the nozzle 113 is opened, and the greater the flow rate of the liquid sprayed out. Under this design, the degree of pressing of the pressing member 3 can be used to control the lead screw motor 213 to drive the lead screw output shaft 2131 to move to the corresponding position to achieve stepless flow adjustment and form a multi-level flow adjustment effect.

[0055] Similarly, if a smaller flow rate is desired, the pressing element 3 can be released accordingly. The lower end of the pressing element 3 will then move outward a certain distance under the restoring force of the elastic restoring element 4, simultaneously driving the encoder 2's rotating shaft 21 to reset a certain distance. At the same time, the encoder 2 transmits pulse data generated by the rotation of its shaft 21 to the control center. The control center reduces the gas supply in the pressure chamber 1112 based on the received pulse data. Then, the first spring 214 and the second spring 215 use their extension force to drive the piston 212 and the ejector pin 112 forward a certain distance, thereby reducing the nozzle flow rate. The effect of the outlet of 113 is that the control center will also send an electrical signal to the lead screw motor 213 through the received pulse data, so that the lead screw motor 213 controls the lead screw output shaft 2131 to move forward a corresponding distance, so as to limit the endpoint when the ejector pin 112 and the piston 212 move backward. That is, the further the lower end of the pressing member 3 is, the farther the ejector pin 112 moves forward, the smaller the outlet of the nozzle 113 is opened, and the smaller the flow rate of liquid spraying will be, until the lead screw output shaft 2131 of the lead screw motor 213 moves to the preset origin, then the ejector pin 12 will completely close the outlet of the nozzle 113 to prevent liquid leakage.

[0056] In summary, this invention, through the design of the handle body 1, encoder 2, pressing element 3, elastic reset button 4, and sensor 5, allows the operator to hold and move the handle body 1 by hand. The flow rate of the sprayed liquid can be adjusted by pressing and releasing the pressing element 3. This is very convenient even when frequent changes in the flow rate of the liquid on the automatic spray gun are needed, and is beneficial for use during drag-and-drop teaching. Furthermore, this invention allows for convenient one-handed operation, eliminating the need for two hands to adjust the flow rate.

[0057] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
