Description

Technical Field

[0001] The invention relates to the field of trouser button processing, and in particular to a method for adjusting the punching stroke of a trouser button binding machine. Background Art

[0002] In the production process of pants, there is generally a production process of binding pants buttons. With the development of technology, many pants button binding jobs have begun to be completed by machines. However, the pants button binding equipment in the prior art generally sets a sewing needle and a pants button binding platform, positions the pants button on the binding platform, and then manually aligns the pants and the pants button, and then the sewing needle drives the sewing thread to sew the pants button on the binding platform onto the pants. The efficiency is low, and the sewing thread is easy to loosen and break, the service life is short, the sewing is difficult, and the qualified rate is low.

[0003] In addition, there are also some devices that use stamping to bind trouser buttons. However, in the prior art, the upper die of the stamping-type trouser button binding device uses a fixed stamping pressure drop to perform the stamping operation. The upper die is provided with a pressure detection mechanism. When the upper die squeezes the trouser button, the pressure will gradually increase. When the pressure detection mechanism detects that the pressure reaches a certain level, the upper die rises and returns to complete the stamping operation. However, the quality of the incoming trouser buttons is unstable, and the pressure bearing capacity of different trouser buttons is different. For example, some trouser buttons are thicker, or the trouser buttons form a certain fold on the edge during manufacturing, which will affect the pressure bearing capacity of the trouser buttons. The fixed stamping pressure of the upper die may over-punch or under-punch trouser buttons with different pressure bearing capacities, resulting in uneven quality of the trouser buttons after binding, low binding qualification rate, and low overall efficiency.

[0004] Therefore, it is necessary to provide a method for adjusting the punching stroke of a trouser button binding machine to solve the above technical problems. Summary of the invention

[0066] The following is an embodiment of a method for adjusting the punching stroke of a trouser button binding machine provided by the present invention, which can solve the above technical problems.

[0067] Please refer to Figure 1 and Fig.10 ,in Figure 1 The present invention is a schematic structural diagram of a trousers button binding machine in a method for adjusting a punching stroke of the trousers button binding machine. Fig.10 The present invention is a flow chart of a method for adjusting the punching stroke of a trouser button binding machine.

[0068] In the figures, structurally similar elements are denoted by the same reference numerals.

[0069] The present embodiment provides a method for adjusting the punching stroke of a trouser button binding machine, which is used to bind male and female buttons to two sides of trouser cloth, wherein the female button is provided with an insertion hole, and both sides of the male button are provided with inserts for plugging into the insertion hole.

[0070] The trouser button binding machine of this embodiment comprises an upper die assembly 11 and a lower die assembly 12 . The upper die assembly 11 is arranged above the lower die assembly 12 in a liftable manner.

[0071] Among them, the upper mold assembly 11 includes an upper module 111 and a positioning member 112. The positioning member 112 can be elastically rotatably connected to the bottom of the upper module 111. A clamping space 116 is formed between the positioning member 112 and the upper module 111. The positioning member 112 clamps the male buckle in the clamping space 116 through elastic rotation, and the insert protrudes from the bottom surface of the positioning member 112.

[0072] The lower die assembly 12 includes: a base 121, a lower die plate 127 and a punch 126. The lower die plate 127 is elastically slidably connected to the base 121, the sliding direction of the lower die plate 127 is consistent with the lifting direction of the upper die assembly 11, the punch 126 is fixedly connected to the base 121, the lower die plate 127 is provided with a female buckle positioning groove for positioning the female buckle, a punch hole 1231 is provided on the bottom surface of the female buckle positioning groove, the punch 126 extends in the punch hole 1231, and the punch 126 is opposite to the insert of the male buckle in the clamping space 116.

[0073] When the upper mold assembly 11 descends, the insert of the male buckle is inserted into the insertion hole of the female buckle, and at the same time, the lower mold plate 127 is pushed down together, and the male buckle, trouser cloth, and female buckle descend together. The punch 126 punches the insert to bend the insert, thereby binding the male buckle and the female buckle to the two sides of the trouser cloth.

[0074] Please refer to Figure 1 The trouser button binding machine in this embodiment also includes a frame, an upper mold assembly 11 is arranged at the upper end of the frame, an operating platform is arranged at the bottom of the frame, and a lower mold assembly 12 is arranged on the operating platform. Specifically, the upper mold assembly 11 is driven to rise and fall by a corresponding lifting drive mechanism, and the lifting drive mechanism is arranged in a device box 14, and the device box 14 is arranged at the upper end of the frame. The outer surface of the device box 14 is provided with a touch screen control panel 15, a power switch 16 and an emergency stop switch 17.

[0075] The stamping stroke adjustment method includes the following steps:

[0076] Step S11: fix the female buckle on the lower mold assembly 12 and fix the male buckle on the upper mold assembly 11.

[0077] Step S12: The user sets the target stamping pressure, and performs stamping operations on the female buckle and the male buckle based on the target stamping pressure. The pressure sensor detects the actual stamping pressure, and the displacement sensor records the stamping distance and uses it as the debugging stamping distance. When the pressure sensor detects that the actual stamping pressure is greater than or equal to the target stamping pressure, the lifting drive mechanism can control the upper mold assembly 11 to rise and return.

[0078] Step S13: The user adjusts the target stamping pressure based on the result of the stamping operation and the actual stamping pressure detected by the pressure sensor until the result of the stamping operation meets the preset requirements.

[0079] It should be noted that the preset requirement refers to whether the degree of bonding between the female buckle and the male buckle meets the requirement. If the bonding between the female buckle and the male buckle is weak, the target stamping pressure is increased. If the bonding between the female buckle and the male buckle is strong, the target stamping pressure is reduced. If the stamping result does not meet the preset requirement, the new male buckle and female buckle are replaced for stamping again.

[0080] Step S14: When the result of the punching operation meets the preset requirements, the debugging punching distance recorded by the displacement sensor in the punching operation that meets the preset requirements is used as the working punching distance. That is, a plurality of different target punching pressures are used for punching debugging, and debugging is performed to know which punching distance can punch out a trouser button that meets the preset requirements.

[0081] Step S15: Based on the working punching distance, the lifting and lowering drive mechanism is controlled to complete the punching and binding operation of the male buckles and female buckles of the same batch. In this way, it is no longer necessary to monitor the punching pressure in real time during the punching process, and the work efficiency is high.

[0082] In this embodiment, step S11 may specifically include: clamping the male buckle in the clamping space 116, with the insert protruding out of the bottom surface of the positioning member 112, and positioning the female buckle in the female buckle positioning groove.

[0083] In this embodiment, step S13 may include: the user may adjust the target stamping pressure through the touch screen control panel 14, and click the "+" or "-" button on the touch screen control panel 15 to increase or decrease the target stamping pressure.

[0084] The binding pressure of the upper mold assembly 11 pressed downward can be adjusted on the touch screen control panel 15, which can be used to adapt to the binding operations of male buckles and female buckles of different models.

[0085] In this embodiment, step S13 may include: after determining the working punching distance, using the target punching pressure corresponding to the current punching operation whose result meets the preset requirements as the basic punching pressure, and using the punching pressure greater than the basic punching pressure as the working punching pressure to control the lifting and lowering drive mechanism to complete the subsequent punching and binding operations of the male and female buckles of the same batch. After determining the working punching distance, a larger working punching pressure can ensure that the trousers buttons can be punched in place every time, and because the punching distance is limited, even if the punching pressure is large, it will not be over-punched and affect the punching quality of the trousers buttons. In this way, the bound trousers buttons have good quality, the bound products are more standardized, the binding pass rate is high, and the overall efficiency is high.

[0086] Please refer to Fig. 9 In this embodiment, the lifting drive mechanism includes a motor 181, a belt transmission assembly, a cylinder 183, a screw rod, and a piston rod 184. The belt transmission assembly is arranged in a transmission box 182.

[0087] The motor 181 and the cylinder body 183 are fixedly arranged in the equipment box 14, the screw is rotatably arranged in the cylinder body 183, and the piston rod 184 is slidably arranged in the cylinder body 183. One end of the piston rod 184 is connected to the screw drive sleeve, and the other end of the piston rod 184 extends to the outside of the cylinder body 183 for connection with the fixed frame 133 of the upper mold assembly 11. The output end of the motor 181 is connected to the screw drive through a belt drive assembly.

[0088] The trouser button binding machine of this embodiment also includes a pressure sensor for detecting the punching pressure and a displacement sensor for detecting the punching distance. The displacement sensor is arranged on the cylinder body 183 and is used to detect the movement of the piston rod 184. The displacement of the piston rod 184 is equal to the punching distance. The pressure sensor can be arranged between the upper mold assembly 11 and the output end of the lifting drive mechanism.

[0089] It should be noted that there are many types of displacement sensors, which can be grating rulers, wire displacement sensors, etc. Different sensors have different installation and connection methods with the cylinder 183. For example, the grating ruler includes a scale grating and a grating reading head. The scale grating is arranged on the inner wall of the cylinder 183, and the grating reading head is arranged on the piston rod 184. The piston rod 184 drives the grating reading head to move, and the movement of the grating reading head can be detected by the scale grating.

[0090] Step S12 in this embodiment includes: the motor 181 drives the screw rod to rotate, thereby causing the piston rod 184 to rise and fall, thereby realizing the punching operation on the female buckle and the male buckle, and the displacement sensor detects the movement of the piston rod to record the punching distance.

[0091] The trouser button binding machine of this embodiment can be compatible with the binding of the first model male button 21a and the first model female button 22a, and the binding of the second model male button 21b and the first model female button 22b.

The first positioning groove 1221 and the second positioning groove 1222 are both opposite to the punching hole 1231. The width of the first positioning groove 1221 is greater than the width of the second positioning groove 1222. The length of the second positioning groove 1222 is greater than the length of the first positioning groove 1221. That is, the second positioning groove 1222 will form a groove on the inner wall surface of the first positioning groove 1221.

In step S11, it also includes: when placing the first type of male buckle 21a, the first type of male buckle 21a is inserted until it contacts the inner wall of the positioning recess 1121 and stops.

[0097] Please refer to Figure 5 In addition, a notch 1122 is provided on the bottom surface of the positioning member 112 near one end of the plug of the male buckle, so that the thickness of the positioning member at the position of the notch 1122 is smaller to adapt to the bending work of the plug, while the thickness of the positioning member at other positions is larger, so that the overall strength and stability of the positioning member 112 are higher.

[0098] Please refer to Figure 4 and Figure 5In this embodiment, a matching groove 1113 is provided on the upper module 111. When the positioning member 112 clamps the male buckle, the positioning member 112 is located in the matching groove 1113.

[0104] The outer periphery of the cylinder 124 is provided with a spring 125, which is compressed between the lower die plate 127 and the bottom plate 1211, and the spring 125 makes the lower die plate 127 slide away from the bottom plate 1211. When the upper die assembly 11 descends, the lower die plate 127 can be pushed to slide away from the bottom plate 1211, so that the punch 126 can punch the insert.

[0105] A limit block 1213 is provided on the fixed column 1212, and a limit groove 1241 is provided on the cylinder 124, and the limit block 1213 is slidably fitted in the limit groove 1241. The cooperation between the limit block 1213 and the limit groove 1241 ensures that the spring 125 will not drive the cylinder 124 to be disconnected from the fixed column 1212.

[0106] Please refer to Figure 3 In this embodiment, one clamping space 116 corresponds to one female buckle positioning groove as one processing group, and multiple processing groups can be set between the upper die assembly 11 and the lower die assembly 12. Specifically, multiple upper die blocks 111 are connected to the same fixing frame 113, and the fixing frame 113 is connected to the output end of the lifting drive mechanism. The fixing frame 113 is provided with a connection groove for connecting multiple upper die blocks 111, and the lower die plate 127 is provided with multiple female buckle positioning grooves. A corresponding number of punches 126 are provided on the fixing column 1212.

[0107] The pressure sensor may be disposed between the fixing frame 113 and the output end of the lifting drive mechanism.

[0108] A gasket 1131 may be provided between the upper module 111 and the fixing frame 113. The stamping distance of the upper module 111 may be changed by providing gaskets 1131 of different numbers or thicknesses. The top of the fixing frame 113 is connected to the output end of the lifting drive mechanism.

[0109] Step 15 also includes:

[0110] Determine the working stamping distances corresponding to different upper modules 111 on the same fixed frame 113 in sequence, calculate the difference in the working stamping distances corresponding to different upper modules 111, fix one upper module 111, and adjust the number or thickness of gaskets 1131 between other upper modules 111 and the fixed frame 113 to eliminate the difference in the working stamping distances corresponding to different upper modules 111, so that when the lifting drive mechanism drives the fixed frame 113 to descend the same distance, multiple upper modules 111 can reach their respective required working stamping distances.

[0111] Based on the fixed working punching distance corresponding to one upper module 111, the lifting drive mechanism is controlled to complete the punching and binding operations of the male buckles and female buckles of the corresponding batches of the subsequent upper modules 111. In this way, the upper modules 111 can punch and bind male buckles and female buckles of different batches and models at the same time, and the binding compatibility is strong.

[0112] Of course, it should be noted that several upper modules 111 can also punch and bind multiple male buckles and female buckles of the same model at the same time.

[0113] Please refer to Figure 1 In this embodiment, the trouser button binding machine also includes a control box 131, and a manual working switch 132, a first manual mode switch 133 and a second manual mode switch 134 arranged on the top surface of the control box 131, and the control box 131 is arranged around the lower template 127.

[0114] When the manual working switch 132 and the first manual mode switch 133 are turned on, the upper mold assembly 11 and the lower mold assembly 12 are brought close to each other to perform binding operations on the first model of male buckle 21a and the first model of female buckle 22a. When the manual working switch 132 and the second manual mode switch 134 are turned on, the upper mold assembly 11 and the lower mold assembly 12 are brought close to each other to perform binding operations on the second model of male buckle 21b and the second model of female buckle 22b. By operating different manual mode switches to control the upper mold assembly 11 to descend and bind the trouser buttons with different binding pressures, different models of trouser buttons can be bound with suitable binding pressures, with high processing compatibility and good processing quality.

[0115] In this embodiment, the trouser button binding machine further includes a foot-controlled switch.

[0116] When the manual operation switch 132, the first manual mode switch 133, and the foot switch are turned on, the upper mold assembly 11 and the lower mold assembly 12 are close to each other to perform binding operations on the first type of male buckle 21a and the first type of female buckle 22a, and when the manual operation switch 132, the second manual mode switch 134, and the foot switch are turned on, the upper mold assembly 11 and the lower mold assembly 12 are close to each other to perform binding operations on the second type of male buckle 21b and the second type of female buckle 22b. This can effectively prevent users from causing damage due to misoperation.

[0117] The working principle of the present invention is as follows: first, the trouser button binding machine is powered on, the power switch 16 is pressed, and the indicator light and the touch screen control panel 15 are powered on and displayed. Before the binding work, the mode adjustment operation can be performed, and before the mode adjustment operation, the lower template 127 is loose and adjustable.

[0118] The specific mode adjustment operations are as follows:

[0119] Click the "mold adjustment page" button on the touch screen control panel 15 and enter the mold adjustment control mode, install the male buckle in the clamping space 116, and install the female buckle in the female buckle positioning groove. Then click the "manual descent" button on the touch screen control panel 15 to slowly descend the upper mold assembly 11, and when the male buckle and the female buckle are close, fine-tune the lower mold plate 127 so that the center positions of the male buckle and the female buckle are aligned, and then tighten the screws on the first plate body 122 to fix the first plate body 122, the second plate body 123 and the cylinder body 124.

[0120] Then, click the "return to origin" button on the touch screen control panel 15, and the upper mold assembly 11 rises to perform the return to origin procedure until the display on the touch screen control panel 15 changes from "need to return to origin" to "return to origin completed", indicating that the return to origin procedure has been completed.

[0121] Then, press the manual working switch 132 and the first manual mode switch 133, and step on the foot switch within the set time, or press the manual working switch 132 and the second manual mode switch 134, and step on the foot switch within the set time. The set time is 2 seconds, for example, the upper mold assembly 11 will automatically descend with the set torque. When the preset torque value is reached, the controller saves the position data and the upper mold assembly 11 automatically returns to the origin.

[0122] Finally, the operator observes whether the bound trouser buttons are qualified. If qualified, the operator clicks the "automatic page" button on the touch screen control panel 15 to return to the automatic working mode. Then the actual binding work can be carried out. If unqualified, the operator can click the "+" or "-" button on the touch screen control panel 15 to fine-tune the pressing position to meet the quality requirements of the trouser button binding.

[0123] The specific binding work of the trouser button binding machine is:

[0124] Install the first type of male buckle 21a or the second type of male buckle 21b in the clamping space 116, install the first type of female buckle 22a or the second type of female buckle 22b in the female buckle positioning groove, place the trouser cloth on the lower template 127, and align the target binding position of the trouser cloth with the female buckle.

[0125] When binding the first model male buckle 21a and the first model female buckle 22a, the hand presses the manual working switch 132 and the first manual mode switch 133 at the same time, and the foot switch is stepped on within the set time, the upper mold assembly 11 descends, and the insert of the first model male buckle 21a is inserted into the insert hole of the first model female buckle 22a, and at the same time, the lower mold plate 127 is pushed down together, the male buckle, trouser cloth, and female buckle descend together, and the punch 126 punches the insert to bend the insert, so that the first model male buckle 21a and the first model female buckle 22a are bound and connected on both sides of the trouser cloth, and the binding action is automatically completed.

[0126] When binding the second model of male buckle 21b and the second model of female buckle 22b, the hand presses the manual working switch 132 and the second manual mode switch 134 at the same time, and the foot switch is stepped on within the set time, the upper mold assembly 11 descends, and the insert of the second model of male buckle 21b is inserted into the insert hole of the second model of female buckle 22b, and at the same time, the lower mold plate 127 is pushed down together, the male buckle, trouser cloth, and female buckle descend together, and the punch 126 punches the insert to bend the insert, so that the second model of male buckle 21b and the second model of female buckle 22b are bound and connected to the two sides of the trouser cloth, and the binding action is automatically completed.

[0127] When an emergency occurs, the emergency stop switch 17 is pressed, and the upper mold assembly 11 automatically returns to the original point, effectively preventing safety accidents.

[0128] This has completed the binding process of the trouser button binding machine of this preferred embodiment.

[0129] The trouser button binding machine of this embodiment is connected by elastically rotating the positioning piece on the upper module. Before the trouser button is bound, the male button is clamped in the clamping space. After binding, the male button insert is inserted into the female button insertion hole, and the insert is bent so that the male button and the female button are fixedly connected to the two sides of the trouser cloth. At the same time, because the positioning piece can be rotated, the male button can slide out of the clamping space when the upper mold assembly rises. The male button and the female button are connected tightly, not easy to be damaged and have a long service life. At the same time, the processing efficiency is high and the qualified rate is high.

[0130] In addition, the stamping stroke adjustment method of the trouser button binding machine of the present embodiment debugs the stamping operation by adjusting the target stamping pressure, and uses the debugging stamping distance recorded by the displacement sensor in the current stamping operation when the result meets the preset requirements during the debugging process as the working stamping distance, and then based on the working stamping distance, controls the driving of the lifting and lowering drive mechanism to complete the subsequent stamping and binding operations of the male and female buttons of the same batch. In this way, the upper mold assembly will descend to the set position each time to complete the stamping, and trouser buttons with different pressure-bearing capacities can be stamped and bound with high quality, with good stamping effect, more standardized products after binding, and high binding qualification rate, high control accuracy, strong stability, easy operation, and safety and reliability.

[0131] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
