An automatic riveting machine

Abstract

The present invention discloses an automatic riveting machine. The technical solution of the present invention is to set a first mechanical vibration plate and a second mechanical vibration plate on both sides of the frame. The mechanical vibration plates on both sides respectively transport the collected male and female buckles to their respective first buckle feeding mechanisms and second buckle feeding mechanisms. The first buckle feeding mechanism pushes the transported buckles out from its interior. The male buckle is received by the buckle base after arriving at the upper mold mechanism. After the buckle base receives the buckle, the female buckle arrives at the lower mold mechanism. Thereafter, the upper and lower mold mechanisms rotate the buckle according to a predetermined angle. At the same time, the cloth padding mechanism pads the cloth between the upper and lower mold mechanisms and punches it through the punching mechanism. Then the upper mold mechanism descends and cooperates with the lower mold mechanism to punch and rivet the cloth pad between the male and female buckles. The present invention has the beneficial technical effects of more accurately adjusting the buckle angle during pushing, more accurately rotating the buckle to the required riveting angle during rotation riveting, and more automated cloth padding process operation process.

Description

Technical Field

[0001] The present invention relates to the technical field of automated processing equipment, in particular to an automatic riveting machine. Background Art

[0002] In the clothing automation industry, the automatic riveting machine is a riveting equipment developed based on the cold rolling principle. The equipment has a compact structure, stable performance, and convenient and safe operation. Specifically, the button outlet seat of the first button feeding mechanism receives the buttons transported from the mechanical vibration plate, and then the buttons are pushed from the inside of the button outlet seat to the outside by a cylinder drive, and then the buttons are sent to the upper and lower mold mechanisms equipped with the button base for buttoning. The buttons have angle requirements. In the process flow, the buttons need to be aligned during the pushing process of the button outlet seat to facilitate the buttons to maintain the correct direction during subsequent buttoning to achieve smooth riveting. The existing technology aligns the buttons manually, but the accuracy of manual alignment is poor and needs to be solved; at the same time, the pushed buttons need to be angled according to objective needs. The punching and riveting are performed after rotating the male and female pieces by degrees. The existing technology manually identifies the riveting direction and angle of the male and female pieces, which not only has poor accuracy but also reduces the factory's production efficiency, which needs to be solved. In addition, in order to ensure the stability and safety of the automatic riveting machine during use, the automatic riveting machine often needs to install a pad when buttoning to ensure the service life of the pants. After installing the pad, this position is more resistant to tension, ensuring the tensile strength of the button at this position when the pants are in normal use. In the pad placement operation of the existing technology, the factory often uses manual or mechanical means to grab the cut and formed pad, and after grabbing, the pad is placed under the riveted part for stacking to achieve the buffering purpose during punching and riveting. The existing technology has a low degree of automation in the pad setting, and the pad placement operation cannot be conveniently performed, which needs to be solved. Summary of the Invention

[0003] The main purpose of the present invention is to propose an automatic riveting machine, which aims to solve the technical problems of poor accuracy in manual operation of aligning or adjusting the position of buttons during the pushing process of the automatic riveting machine in the existing technology, and low efficiency in manual operation of placing the pad.

Specifically, the guiding device, feeding device and cutting device of the padding cloth mechanism are used to realize the padding cloth process operation process. The original uncut cloth strip first enters from the guiding device, and then is driven by the feeding device to move the cloth strip.

[0054] The present invention provides an automatic riveting machine.

[0055] In the embodiment of the present invention, Figures 1 to 24As shown, the automatic riveting machine includes a frame 5, a mechanical vibration plate 6, a first button feeding mechanism 1, a button base 2, an upper and lower mold mechanism 3, a cloth pad mechanism 4 and a punching mechanism (not shown). The mechanical vibration plate 6 includes a left mechanical vibration plate 61 and a right mechanical vibration plate 62. The left mechanical vibration plate 61 and the right mechanical vibration plate 62 are respectively arranged on both sides of the frame 5. In order to facilitate the placement of the mechanical vibration plate 6, brackets 52 are provided on both sides of the column 51 of the frame 5. The first button feeding mechanism 1 is arranged inside the frame 5 and connected to the mechanical vibration plate 6. At the same time, the first button feeding mechanism 1 is used to transport the buttons transported by the mechanical vibration plate 6 toward the upper and lower mold mechanisms 3. The lower mold mechanism 3 adopts a rotating structure or a non-rotating structure. When the rotating structure is adopted, the horizontal angle of the male and female buckles can be adjusted. When the non-rotating structure is adopted, the horizontal angle of the male and female buckles cannot be adjusted. It also includes a button base. The button base 2 is arranged at the end of the upper and lower mold mechanisms 3, and is used to collect the buttons pushed out by the first button feeding mechanism 1. The cloth padding mechanism 4 is used to cut the original cloth strips into cloth pads of predetermined sizes and guide them to a predetermined position. The punching mechanism is used to punch holes in the cloth padding. The punching mechanism includes at least one punching head and a driving device for driving the punching head to move. Since the punching mechanism is a prior art, it will not be described here.

[0056] Specifically, the original cloth strip usually refers to a cloth with a fixed width and a length of several meters, tens of meters, or hundreds of meters. It is processed into a roll or a bundle and cut into predetermined sizes by the cloth padding mechanism 4. For example: assuming that the original cloth strip is fixed at 2 cm wide and 50 meters long, and the predetermined size to be cut is assumed to be 2 cm wide and 5 cm long, the original cloth strip will be transported to the front position of 2 cm wide and 5 cm long and will stop. Then the punching mechanism will punch the cloth padding at this position and rivet the buttons (usually male and female buttons). After the riveting is completed, it will be cut and the cycle will be repeated.

[0057] In an embodiment of the present invention, the first button feeding mechanism 1 includes a button ejection seat 11, a button feeding cylinder 12 and a button feeding push rod 13 which is transmission-connected to the button feeding cylinder 12. The button ejection seat 11 is internally provided with a pushing channel 111 which limits a predetermined pushing direction for the button. A feed port 113 is provided on the side of the button ejection seat 11 corresponding to the feeding direction. The feed port 113 is communicated with the pushing channel 111. One end of the pushing channel 111 faces the button feeding cylinder 12, and the other end faces the button base 2. The button feeding push rod 13 is slidably provided in the pushing channel 111. During operation, the button feeding cylinder 12 pushes the button feeding push rod 13, and the button feeding push rod 13 is pushed toward one end of the interface device along the pushing channel 111. In addition, the button feeding push rod 13 is provided with a clamping member 14 for clamping the button at one end close to the button base 2. The clamping member 14 can clamp the button so that it is kept in the correct direction and angle to be fed out.

[0058] In an embodiment of the present invention, the second button feeding mechanism is connected to the second mechanical vibration plate, and the second button feeding mechanism is used to transport the buttons delivered from the second mechanical vibration plate toward the lower mold mechanism.

[0059] In an embodiment of the present invention, the clamping member 14 includes a fixed side 141 for fixing the button and a lifting and pressing side 142 for adjusting the clamping state. The fixed side 141 and the lifting and pressing side 142 are integrally formed at the end of the button delivery push rod 13. In some other embodiments, the fixed side 141 and the lifting and pressing side 142 can be connected in a split manner. The advantage of the integral molding is that the structure is more stable.

[0060] In some preferred embodiments of the present invention, in order to position the pushing distance of the button delivery push rod 13, the top of the pushing channel 111 of the button ejector seat 11 is at least partially opened, and a control pressure block 16 for limiting the moving position of the button delivery push rod 13 is provided at the opening at the top of the pushing channel 111, and the end of the control pressure block 16 at least partially extends from the top of the pushing channel 111.

[0061] Specifically, the control pressing block 16 is preferably provided with two blocks, and the control pressing block 16 includes a first control pressing block 16A and a second control pressing block 16B. The first control pressing block 16A is provided at the lifting and pressing side 142 position at the initial position where the button feeding push rod 13 does not feed the button, and the second control pressing block 16B is provided at the lifting and pressing side 142 position at the end position where the button feeding push rod 13 feeds the button. The movement range of the button feeding push rod 13 is limited between the first control pressing block 16A and the second control pressing block 16B. Figures 4 to 9 As shown, the first control pressing block 16A is set at the lifting and pressing side 142 position at the initial position of the button feeding push rod 13 without feeding the button, and the second control pressing block 16B is set at the lifting and pressing side 142 position at the end position of the button feeding push rod 13 feeding the button.

[0062] Specifically, at the initial position and the end position of the button delivery push rod 13, the lifting and pressing side 142 abuts against the first control pressure block 16A and the second control pressure block 16B respectively, and the control pressure block 16 abuts against one end of the lifting and pressing side 142 and extends into the pushing channel 111, and / or the lifting and pressing side 142 is higher than the fixed side 141 in the horizontal direction. The above structure is used to better realize the clamping function.

[0063] Furthermore, in order to be able to control the use status of the lifting and pressing side 142 and the fixed side 141, the lifting and pressing side 142 is provided with a first inclined surface 1421, a second inclined surface 1422 and a third action surface 1423, the first control pressure block 16A is provided with a third inclined surface 16A1 and a first action surface 16A2 at a position corresponding to the first inclined surface 1421, the second control pressure block 16A is provided with a fourth inclined surface 16B1 at a position corresponding to the second inclined surface 1422, and the second control pressure block 16B is further provided with a second action surface Using surface 16B2, when in the corresponding position, the first inclined surface 1421 abuts against the third inclined surface 16A1, and the second inclined surface 1422 abuts against the fourth inclined surface 16B1. When the first action surface 16A2 or the second action surface 16B2 abuts against the third action surface 1423, the lifting and pressing side 142 is in a downward pressing state. When the first action surface 16A2 or the second action surface 16B2 is out of abutment with the third action surface 1423, the lifting and pressing side 142 is in a lifted state.

[0064] It can be understood that when the aforementioned first inclined surface 1421 abuts against the third inclined surface 16A1, the button feeding push rod 13 stops, and at the same time the lifting and pressing side 142 is pressed down, and the fixed side 141 is in a raised state at this time, for receiving the buttons transported from the feed port 113, and when the aforementioned second inclined surface 1422 abuts against the fourth inclined surface 16B1, the button feeding push rod 13 stops moving after the abutment, and the lifting and pressing side 142 and the fixed side 141 are both in a pressed down state, which is conducive to sending the buttons into the subsequent button base 2.

[0065] Furthermore, in order to control the stable installation of the pressure block 16, a through hole 161 is opened at one end of the control pressure block 16, and a first through hole 112 is opened corresponding to the side of the button seat 11. The pressure block is fixedly connected to the side of the button seat 11 by passing the first through hole 112 and the first through hole 112 through a connecting piece.

[0066] Furthermore, the first control pressing block 16A and the second control pressing block 16B have different areas occupied by the top surface of the pushing channel 111. This is because the size of the area occupied by the control pressing block 16 needs to be adapted to its function. The first control pressing block 16A at the feed port 113 docked with the external mechanical vibration plate 6 is set larger. This is to ensure stable clamping when conveying the buttons, so as to prevent the fixed side 141 from being lifted for too short a time and not getting stuck in the buttons. It is also worth noting that when the control pressing block 16 is set larger, more holes 161 and first through holes 112 can be set on the side, such as Figure 4 As shown, the first control pressing block 16A is provided with two pairs of holes 161 and first vias 112 for fixed connection therewith.

[0067] In an embodiment of the present invention, the button base 2 includes two settings, namely a male button base 21 and a female button base 22. The male button base 21 includes a first seat body 211 and a first accommodating portion 212. The first accommodating portion 212 is a clip. The first seat body 211 and the first accommodating portion 212 are movably connected and after the first seat body 211 and the first accommodating portion 212 are movably separated, a accommodating chamber 213 for receiving the button is defined therebetween. During operation, the button is clamped in the aforementioned accommodating chamber 213. In some other embodiments, the first seat body 211 and the first accommodating portion 212 can be fixedly connected or integrally formed, leaving a portion of the accommodating chamber 213 to achieve the basic placement function of the button.

[0068] In some embodiments of the present invention, Figure 6 As shown, the first seat body 211 and the first accommodating portion 212 are connected by a pin 214, and the two ends of the clip are correspondingly installed at the two ends of the pin 214. The first accommodating portion 212 swings downward and back with the two ends of the pin 214 as fulcrums to expand and shrink the accommodating chamber 213.

[0069] In other embodiments of the present invention, the first base body 211 and the first accommodating portion 212 can also be connected by a lifting shaft, and the two ends of the clip are correspondingly installed at the two ends of the lifting shaft. The first accommodating portion 212 is lifted and lowered with the two ends of the lifting shaft as fulcrums to expand and shrink the accommodating chamber 213. Specifically, by pulling the lifting shaft, the first accommodating portion 212 is separated from the first base body 211. The lifting shaft can be specifically set by mechanical telescopic, elastic telescopic, etc.

[0070] In an embodiment of the present invention, the button feeding push rod 13 further includes a limiting component 15 for placing a specific button, and the limiting component 15 includes a first limiting protrusion 151 and a second limiting protrusion 152. The first limiting protrusion 151 and the second limiting protrusion 152 form an open slot, and the curvature of the top surface of the second limiting protrusion 152 in contact with the button matches the shape of the button. It is worth noting that the characteristic of the limiting component 15 is that it can place special-shaped buttons, such as Figure 9 and Figure 10 As shown, the limiting component 15 of this embodiment is used to place the trousers hook, the first limiting protrusion 151 is placed on the lower part of the trousers hook, and the upper part of the trousers hook falls on the second limiting protrusion 152. In some other embodiments, the limiting component 15 can be set to other shapes that can adapt to specific buttons. This is part of the existing technology and will not be elaborated on.

[0071] For ease of understanding, the following content uses the technical features of the preferred embodiment to illustrate the working principle of the first button feeding mechanism 1: the buttons enter the button outlet seat 11 from the feed port 113 on the button outlet seat 11, and at this time the button feeding push rod 13 is located at the first control pressure block 16A, and the first inclined surface 1421 of the lifting and pressing side 142 abuts against the third inclined surface 16A1 of the first control pressure block 16A, so that the lifting and pressing side 142 is lifted to facilitate the entry of the buttons, and the buttons are fed into the position below the fixed side 141 of the clamping member 14 through the pushing channel 111, and then the button feeding cylinder 12 pushes the button feeding push rod 13 to push it from the first control pressure block 16A to the second control pressure block 16B. During the process, the third action surface 1423 abuts against the first action surface 16A2. The lifting and pressing side 142 is converted from a lifted state to a pressed down state to tighten the button, and the fixed side 141 maintains the angle of clamping the button to ensure the stability of the conveying process. After the button feeding cylinder 12 pushes the button into the accommodating chamber 213 between the first seat body 211 and the first accommodating portion 212, the lifting and pressing side 142 abuts against the fourth inclined surface 16B1 of the second control pressure block 16B from the second inclined surface 1422 until the third action surface 1423 abuts against the second action surface 16B2, so that the lifting and pressing side 142 is lifted to facilitate the discharge or removal of the button. The button feeding push rod 13 completes a back and forth movement between the first control pressure block 16A and the second control pressure block 16B in the pushing channel 111, thereby repeatedly completing the feeding and discharge of the button.

[0072] In an embodiment of the present invention, when the upper and lower mold mechanisms adopt a rotating structure technical solution, the upper and lower mold mechanisms are used to automatically rotate the buttons to a predetermined angle and rivet the buttons to the padding. The upper and lower mold mechanisms 3 include an upper mold mechanism 31 and a lower mold mechanism 32. The upper mold mechanism 31 includes a first rotating motor 316, a push shaft 311 directly or indirectly connected to the first rotating motor 316, a rotating seat 312, a positioning member 314 cooperating with the rotating seat 312, a male button base 21 connected to the rotating seat 312, and a shell 313. The rotating seat 312 is provided with a The cam groove 3121 is used to adjust the rotation angle, and the rotating seat 312 can rotate horizontally relative to the pushing shaft 311. When the first rotating motor 316 indirectly drives the rotating seat 312 to move upward or downward, the positioning member 314 can move within the length range of the cam groove 3121 and, under its action, the rotating seat 312 rotates horizontally, synchronously driving the male button base 21 to rotate. The lower mold mechanism 32 includes a second rotating motor 321, a transmission shaft 322 and a female button base 22. When the second rotating motor 321 rotates, it directly or indirectly drives the female button base 22 to rotate.

[0073] Understandably, if Figure 16 As shown, the upper mold mechanism 31 and the lower mold mechanism 32 can be used in combination to form a double mold set rotation mechanism, and the positions of the upper mold mechanism 31 and the lower mold mechanism 32 are not limited, and which device is used to place the male or female piece of the riveted piece is also not limited. Figure 13 and Figure 16 As shown, it is preferred that the upper mold mechanism 31 is arranged at the top and the lower mold mechanism 32 is arranged at the bottom. This is because the upper mold mechanism 31 is driven by the first rotating motor 316 to push the push shaft 311 and then rotates the rotating seat 312 to rotate the direction of the male button base 21 installed on the upper mold mechanism 31, while the lower mold mechanism 32 is driven by the second rotating motor 321 to rotate the transmission shaft 322 to rotate the direction of the female button base 22. It is more in line with the technical intuition and habit of this technical field to arrange the upper mold mechanism 31 with a pushing function and active riveting at the top, while the lower mold mechanism 32 corresponds to the upper mold mechanism 31 and is arranged at the bottom as the passive riveting party.

[0074] Furthermore, since in the embodiment of the present invention the upper and lower mold mechanisms 3 and the cloth pad mechanism 4 are arranged in an interactive form, the cloth pad mechanism 4 needs to be arranged at the lower position of the upper and lower mold mechanisms 3, so the upper and lower mold mechanisms 3 are arranged at the upper position, and the aforementioned upper mold mechanism 31 is taken as a preferred embodiment of the present invention.

[0075] In an embodiment of the present invention, the upper mold mechanism 31 drives the push shaft 311 by operating the stroke screw rod 317 through the first rotary motor 316, and then the stroke screw rod 317 presses down the crank structure 318. Regarding the driving part, reference can also be made to other driving components of the automatic riveting machine in the prior art.

[0076] In an embodiment of the present invention, the push shaft 311 is at least partially installed inside the rotating seat 312, and the shell 313 is provided with a accommodating chamber 3131 that penetrates the shell 313 body. The rotating seat 312 is placed in the accommodating chamber 3131, and the shell 313 is provided with a second through hole 3132 for installing the positioning member 314.

[0077] In an embodiment of the present invention, the cam groove 3121 is a special-shaped groove, which is arranged vertically along the rotating seat 312. The cam groove 3121 includes an upper groove 3121A and a lower groove 3121B. The upper groove 3121A is connected to the lower groove 3121B, and the upper groove 3121A and the lower groove 3121B are not on the same straight line.

[0078] It can be understood that the setting of the cam groove 3121 is determined by the starting point and landing point of the cam groove 3121 structure to determine the rotation angle. Figure 14 The situation shown is that the cam groove 3121 structure is set with the quarter circle range of the rotating seat 312 as the starting point and the landing point, that is, the setting is connected through the upper groove 3121A to the lower end groove. The setting conditions of other angles can be simply inferred through this embodiment and will not be repeated here.

[0079] In an embodiment of the present invention, in order to enable smoother spiral propulsion, the surface of the pushing shaft 311 is provided with a spiral pattern 3111 for enhancing the smoothness of rotation of the rotating seat 312. The spiral pattern 3111 is a groove body with a spiral direction and an inward concave shape.

[0080] Specifically, the spiral pattern 3111 is a groove that is spirally oriented and inwardly concave. When the rotating seat 312 rotates around the pushing shaft 311, the resistance between the rotating seat 312 and the pushing shaft 311 will be reduced due to the setting of the spiral pattern 3111. In some other embodiments, a smooth material such as gel or fiber can be wrapped between the pushing shaft 311 or the rotating seat 312 to achieve the same effect.

[0081] In an embodiment of the present invention, the positioning member 314 includes a rotor 3141 and a first bearing 3142 abutting against one end of the rotor 3141. One end of the rotor 3141 extends into the cam groove 3121, and the first bearing 3142 extends into the second through hole 3132. The rotor 3141 is fixed by the first bearing 3142 so that one end of the rotor 3141 remains extended into the cam groove 3121.

[0082] Furthermore, in order to better fix the positioning piece 314, a fixing block 315 for fixing the positioning piece 314 is provided on the side of the shell 313, and another second bearing 3143 is provided at the other end of the rotor 3141. The second bearing 3143 is connected to the fixing block 315, and an embedding hole (not shown) is opened on the fixing block 315. The second bearing 3143 is embedded in the embedding hole. The fixing block 315 and the shell 313 are fitted together and fixedly connected.

[0083] In an embodiment of the present invention, the female button base 22 includes a second accommodating portion 222 and a second seat body 221. The second accommodating portion 222 is a clamping portion, which is movably connected to the second seat body 221. The clamping portion clamps the button by performing a lifting movement on the second seat body 221.

[0084] In some other embodiments of the present invention, the aforementioned male button base 21 and female button base 22 can be interchanged, that is, the male button base 21 is set in the lower mold mechanism 32, and the female button base 22 is set in the upper mold mechanism 31. This structure can still achieve basic functions.

[0085] Furthermore, the second accommodating portion 222 is connected to a reset component 223 for resetting. In actual operation, the second accommodating portion 222 is pressed down to make the external nail button fall on the second base body 221, and then the second accommodating portion 222 rebounds to the initial position to clamp the nail button between the second accommodating portion 222 and the second base body 221 to complete the work. Figure 13 and Figure 15As shown, the reset component 223 is preferably a spring. In some other embodiments, the spring can also be replaced by components with elastic properties such as elastic fibers, torsion springs, rubber, sponges, etc.

[0086] The cloth padding mechanism 4 includes a guide device 41 for guiding the cloth strips to move to a predetermined position, a cloth feeding device 42 for transporting the cloth strips, and a cutting device 43 for cutting the cloth strips transported to the predetermined position by the cloth feeding device 42 into cloth pads of predetermined specifications and sizes. The guide device 41 is provided with a cloth strip channel 415, and the cloth feeding device 42 includes a main roller 421, a driving component 422 for driving the main roller 421 to rotate, a pressure wheel 423, and a tension adjustment mechanism 424 for adjusting the gap between the pressure wheel 423 and the main roller 421. The main roller 421 and the driving component 422 are connected by transmission.

[0087] In an embodiment of the present invention, Figure 21 As shown, the guide device 41 includes a guide plate 411 and a cover plate 412. A cloth channel 415 is defined internally between the guide plate 411 and the cover plate 412. The first end of the cloth channel 415 is a cloth inlet 413, and the other end is a cloth outlet 414. The cloth enters the cloth channel 415 through the cloth inlet 413, and is then sent out from the cloth outlet 414 to enter the subsequent cloth feeding device 42.

[0088] Furthermore, if Figures 17 to 21 As shown, the guide device 41 also includes a limit plate 416 arranged on both sides or between the guide plate 411 and the cover plate 412, and the limit plate 416 includes a left limit plate 4161 and a right limit plate 4162. The left limit plate 4161 and the right limit plate 4162 are arranged relative to each other. The limit plate 416 can limit the cloth strip in the cloth strip channel 415 in the horizontal direction to prevent the cloth strip from moving abnormally in the horizontal direction when moving in the cloth strip channel 415, so that the cloth strip can be smoothly moved out from the cloth outlet 414.

[0089] In an embodiment of the present invention, Figure 17 and Figure 22As shown, in the cloth feeding device 42, the driving assembly 422 includes a first driving device 4221 and a transmission mechanism 4222, the transmission mechanism 4222 includes a driving wheel 42221, a driven wheel 42222 and a transmission belt 42223, the driving wheel 42221 is connected to the driven wheel 42222 through the transmission belt 42223, the output shaft of the first driving device 4221 is connected to the driving wheel 42221, during the driving process, the output shaft of the first driving device 4221 rotates the driving wheel 42221, and the driving wheel 42221 then drives the driven wheel 42222 to rotate through the transmission belt 42223, the first driving device 4221 preferably uses a rotating motor, in some other embodiments, the first driving device 4221 can also use a telescopic cylinder, and indirectly produce a rotation effect through a swing arm or other mechanical structures, this is the existing technology and will not be elaborated.

[0090] In an embodiment of the present invention, the tension adjustment mechanism 424 includes a mounting block 4241 for fixing the pressure wheel 423 and an elastic component 4242 for adjusting the swing angle of the mounting block 4241. The elastic component 4242 includes an elastic component 42421 for adjusting the angle of the mounting block 4241 and a top rod 42422 for the elastic component 42421 to abut against. The function of the tension adjustment mechanism 424 is to adjust the gap between the main roller 421 and the pressure wheel 423 when a cloth strip larger or smaller than the predetermined cloth strip passes through the main roller 421 and the pressure wheel 423, so as to be suitable for cloth strips of various sizes.

[0091] Specifically, one end of the mounting block 4241 is mounted on the pressure wheel 423, and the other end is mounted on the elastic component 42421. When the cloth strip is large, the pressure wheel 423 is lifted upward, and the mounting block 4241 is lifted at one end of the pressure wheel 423, and the other end of the mounting block 4241 is pressed down, and then the elastic component 42421 is compressed toward one end of the top rod 42422. When the cloth strip is small, the pressure wheel 423 is pressed down, that is, the above-mentioned components move in opposite directions. The elastic component 42421 is preferably a spring. In some other embodiments, it can also be replaced by rubber, sponge, torsion spring or other components with the same elastic effect. This is part of the prior art and will not be elaborated on.

[0092] In an embodiment of the present invention, the cloth feeding device 42 is provided with a guide 425 at the cloth outlet end of the main roller 421 for aligning the cloth strip with the cutting device 43. The guide 425 is provided with an entrance 4251 and an exit 4252. The position of the knife holder 434 corresponding to the exit 4252 is provided with a third through hole 4342. That is, after the cloth strip is pushed out from the cloth feeding device 42, the exit 4252 of the guide 425 is aligned with the third through hole 4342 of the knife holder 434, and the cloth strip extends from the exit 4252 into the third through hole 4342, and then the cutting device 43 cuts the cloth strip.

[0093] In an embodiment of the present invention, Figure 23 and Figure 24 As shown, the cutting device 43 includes a cutter 433 , a cutter holder 434 for the cutter 433 , and a second driving device 432 for driving the cutter 433 to move relative to the cutter holder 434 .

[0094] Furthermore, the cutting device 43 also includes a push plate 431, and the second drive device 432 is connected to the cutter 433 through the push plate 431. The knife seat 434 is vertically provided with at least one second limiting hole 4341, and the cutter 433 can move up and down in the second limiting hole 4341. At least one first limiting hole 4311 is obliquely provided on the push plate 431, and a transmission component 437 is fixedly installed on the cutter 433. The transmission component 437 passes through the first limiting hole 4311 and the second limiting hole 4341, and the transmission component 437 can move in the first limiting hole 4311 and the second limiting hole 4341 respectively.

[0095] Specifically, the second driving device 432 preferably uses a telescopic cylinder. In some other embodiments, a rotating motor can be selected to cooperate with a swing arm or other mechanical structure to indirectly produce a horizontal pushing effect. This is part of the existing technology and will not be elaborated on.

[0096] It can be understood that the first limiting hole 4311 and the second limiting hole 4341 cooperate to control the movement state of the push plate 431 and the cutter 433. After the aforementioned second driving device 432 pushes the push plate 431, the structural characteristics of the first limiting hole 4311 enable the transmission component 437 to move vertically driven by the push plate 431. At the same time, the structural characteristics of the second limiting hole 4341 are such that the movement trajectory of the transmission component 437 is limited in the vertical direction. The direction of the first limiting hole 4311 is preferably set to an oblique downward direction from left to right. When the second driving component pushes the push plate 431, the transmission component 437 gradually moves to the second limiting hole 4311. The left side of the first limiting hole 4311 is lifted up, and then the cutter 433 extends out to cut the cloth. When the push plate 431 retracts, the transmission component 437 gradually moves to the right side of the first limiting hole 4311 and is pressed down, and the cutter 433 returns to the knife seat 434. In some other embodiments, the direction of the first limiting hole 4311 can be an upward oblique direction from left to right. In this embodiment, the transmission component 437 may fall due to gravity, and the transmission component 437 needs to be fixed to a certain extent. For example, a friction structure such as a sawtooth is provided in the first limiting hole 4311 to increase friction and prevent the transmission component 437 from falling abnormally.

[0097] Furthermore, it also includes at least one third limiting hole 4312 horizontally arranged on the push plate 431, and at least one limiting member 438 passes through the third limiting hole 4312 and is fixedly connected to the knife seat 434. The function of the third limiting hole 4312 is to limit the movement direction of the push plate 431 to the horizontal direction. Furthermore, in order to better limit the horizontal movement of the push plate 431, the limiting member 438 is provided with a fixing portion 4381 for clamping the push plate 431 at one end close to the push plate 431, and the fixing portion 4381 abuts against the push plate 431 to form a limiting effect. Specifically, the push plate 431 is clamped between the fixing portion 4381 and the knife seat 434, and the third limiting hole 4312 abuts against the rod portion 4382 of the limiting member 438.

[0098] In an embodiment of the present invention, the cutting device 43 also includes a spring piece 435 and / or a guide structure 436 for pressing the cutter 433 against the knife seat 434. The spring piece 435 is installed and fixed on the side of the cutter 433 away from the knife seat 434. A movable cavity of the cutter 433 is formed between the spring piece 435 and the knife seat 434. The guide structure 436 is used to guide the padding cut to the required size to a predetermined position. The predetermined position is where the padding needs to be placed below the position where the buttons of the pants need to be riveted.

[0099] Specifically, a fixing hole 4351 is provided on the spring piece 435, and the spring piece 435 is tightly attached to the knife seat 434 through the fixing hole 4351. Through the compression of the spring piece 435, the movement direction of the cutter 433 in the movable chamber during the rising and falling process will be more accurate.

[0100] Specifically, the guide structure 436 is preferably integrally formed on the spring piece 435. The advantage of integral forming is structural stability. The guide structure 436 is a tilted piece, and the guide structure 436 is used to limit the movement direction of the cloth strip after it extends from the active cavity.

[0101] It should be noted that the aforementioned pad can also be called a gasket.

[0102] In the embodiment of the present invention, in order to facilitate the placement of garments to be processed, the frame 5 is provided above the cloth-laying mechanism 4 with a tray 55 for placing the garments to be processed.

[0103] In an embodiment of the present invention, considering the safety during the processing, the frame 5 is connected with a guard 53 at the stamping and riveting position. The guard 53 can be lowered to press the processed fabric, thereby replacing the situation where the staff presses the fabric with their hands. For convenience, the guard 53 can be driven down by a cylinder.

[0104] In an embodiment of the present invention, taking into account the efficiency of the processing process, a red light 54 is connected to the frame 5 at the stamping and riveting position. The function of the red light 54 is to assist in the positioning of the riveting. When in use, the lamp head of the red light 54 can be aligned with the button base 2.
