Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent equipment for clothing production, and specifically relates to an intelligent punching device for clothing production. Background Art

[0002] Clothing production is to cut the fabric according to the template after proofing, and then splice and sew the cut fabric together. In addition, some clothing also needs to punch holes on the edges (such as button holes on denim jackets or suits), and fix the buttons on the clothing through the buttonholes to improve the functionality and decorativeness of the clothing. Punching holes requires a punching device.

[0003] When punching holes in clothing fabrics, the existing punching device usually requires the staff to hold the fabric to fix it and move the part to be punched under the punching knife, and complete the punching by moving the punching knife downward. However, the scraps generated during the punching process will remain inside the punching knife, and the punching knife cannot push out the scraps accumulated inside it. If the punching knife continues to work, the scraps inside will accumulate more and more, causing the punching knife to be unable to completely penetrate the fabric, and thus unable to complete the punching. The staff needs to manually remove the scraps accumulated in the punching knife, resulting in low work efficiency. Summary of the invention

[0007] Furthermore, the limiting groove is divided into a wave groove part and a circumferentially distributed straight groove part, and the straight groove is connected to the wave groove. In the same vertical direction, the distance between the lowest point of the wave groove and the highest point of the straight groove is equal to the height between the connecting hole and the side of the adjacent third passage away from the fixed sleeve.

A protective shell is fixedly connected to the side of the processing bed close to the fixed rod. Two rotating shafts are rotatably connected in the protective shell. A belt is wound between the two rotating shafts through a pulley. The transmission roller away from the second driving member is connected to the adjacent rotating shaft through a transmission device, and the transmission ratio of the transmission device is 1:1.

[0009] Furthermore, the belt between the two rotating shafts is detachably connected to a first plate that is evenly distributed, the first plate is slidably connected to a second plate, a spring is connected between the first plate and the adjacent second plate, through holes are provided on the first plate and the second plate, and the aperture of the through hole of the first plate is smaller than the aperture of the through hole of the second plate.

[0010] Furthermore, the processing bed is fixedly connected to a fixed frame, the fixed frame is slidably connected to a sliding frame, and a spring is connected between the two.

[0013] Furthermore, a support plate is fixedly connected to one side of the processing bed close to the protective shell, and the support plate is in contact and cooperation with the adjacent first plate.

[0014] Furthermore, the processing bed is fixedly connected with a collection box, the collection box is connected with a temporary storage sleeve, the central axis of the temporary storage sleeve coincides with the central axis of the fixed sleeve, and a sensor is installed on the outer side of the temporary storage sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention blows off the scraps remaining inside the punching knife by introducing air into the punching knife, thereby preventing the scraps generated during the punching process from entering the punching knife, making it impossible for the punching knife to be inserted into the fabric again, and affecting subsequent punching operations;

[0017] The punching knife of the present invention rotates while moving downward, and rubs the cloth while squeezing it, which helps to cut the cloth, thereby improving the punching efficiency;

[0018] The present invention clamps and fixes the cloth by relative movement of the first plate and the adjacent second plate, and drives the cloth to move, so that the punching position can be replaced as needed, and the contact area between the fixing member and the cloth is increased by making the first plate and the adjacent second plate contact the cloth, thereby enhancing the stability during the punching process and further improving the punching efficiency.

[0019] The present invention controls the height of the limit frame by making the moving distance of the smoothing roller correspond to the thickness of the cloth, so that the limit frame applies a suitable squeezing force to the second plate, thereby ensuring the clamping force of the second plate and the adjacent first plate on the cloth, and ensuring that both drive the cloth to move;

[0020] The present invention uses a smoothing roller to continuously squeeze the cloth using adjacent springs, flattens the passing cloth, and keeps the cloth in a taut state during the punching process, thereby ensuring the accuracy of the punching position and preventing the cloth from wrinkling and causing the punching position to deviate.

[0021] The present invention enables the first plate and the adjacent second plate to move along the support plate, and the support plate provides a supporting force to the first plate and the adjacent second plate on its upper side, thereby preventing the first plate and the adjacent second plate from deflecting in the upper and lower directions during the movement, thereby preventing the first plate and the adjacent second plate from causing the fabric to deviate.

DETAILED DESCRIPTION

[0035] 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.

[0036] The existing punching device does not have a structure for pushing the material outward inside the punching knife. The scraps generated during the punching process will remain inside the punching knife, causing the punching knife to be unable to penetrate the fabric, affecting subsequent punching operations.

[0037] Embodiment 1: An intelligent punching device for clothing production, combined with Figure 1-Figure 8As shown, it includes a processing bed 1, a fixing rod 2 is fixedly connected to the upper side of the processing bed 1, a control terminal (not shown in the figure) is installed on the processing bed 1, a first driving member 3 is installed on the fixing rod 2, the first driving member 3 is electrically connected to the control terminal, the first driving member 3 is an electric push rod, a fixing sleeve 4 is fixedly connected to the first driving member 3, a first passage 41 is arranged in the fixing sleeve 4, the first passage 41 is a horizontal channel, an air pump is externally connected to the first passage 41, the air pump is used to pump air into the first passage 41, the air pump is electrically connected to the control terminal, a solenoid valve for exhaust is arranged at the connecting pipe between the air pump and the first passage 41, a sliding rod 5 is fixedly connected to the power output end of the first driving member 3, and the sliding rod 5 It is slidably connected to the fixed sleeve 4, and a second passage 51 is provided in the sliding rod 5. The second passage 51 is an L-shaped channel. The second passage 51 is communicated and cooperated with the first passage 41. The second passage 51 moves downward and is communicated with the first passage 41. Four circumferentially distributed third passages 52 are provided in the sliding rod 5. The third passage 52 is an arc-shaped channel. The third passage 52 is communicated with the second passage 51. A punching knife 6 is slidably connected to the sliding rod 5, and a spring is provided therebetween. The punching knife 6 is used to punch holes in the cloth, and the spring is used to reset the punching knife 6. Four circumferentially distributed communicating holes 61 are provided on the upper side of the punching knife 6, and the communicating holes 61 are communicated and cooperated with the lower side of the adjacent third passage 52.

[0038] Combination Figure 8 As shown, the inner wall of the sliding rod 5 is fixed with four circumferentially distributed fixed balls 53, and the outer side of the punch 6 is provided with a limiting groove 62, which is divided into a wave groove part and a circumferentially distributed straight groove part, and the straight groove is connected with the wave groove. In the same vertical direction, the distance between the lowest point of the wave groove and the highest point of the straight groove is equal to the height between the connecting hole 61 and the lower side of the adjacent third passage 52. When the fixed ball 53 moves to the uppermost side of the straight groove part of the limiting groove 62, the connecting hole 61 is connected with the lower side of the adjacent third passage 52, and the four fixed balls 53 are all squeezed and matched with the limiting groove 62. The limiting groove 62 moves downward and rotates under the action of the adjacent fixed balls 53, and the rotation angle is 45°.

[0039] When using the present invention to punch holes in clothing fabric, firstly, the fabric to be punched is placed on the processing bed 1 and fixed by hand, the part of the fabric to be punched is aligned with the lower side of the punching knife 6, and then the first driving member 3 is started through the control terminal, the power output end of the first driving member 3 drives the sliding rod 5 to move downward, and the sliding rod 5 drives the parts inside it to move downward synchronously, when the lower side of the sliding rod 5 contacts and squeezes the fabric, the power output end of the first driving member 3 stops moving, at which time the second passage 51 is connected to the first passage 41, and then the control terminal controls the external air pump to open, the air pump pumps air into the first passage 41, the gas enters the second passage 51 through the first passage 41, the air pressure in the second passage 51 increases, and the air in the second passage 51 pushes the punching knife 6 to move downward, so that the spring between the sliding rod 5 and the punching knife 6 is compressed.

[0040] When the punching knife 6 moves downward, the punching knife 6 drives all the connecting holes 61 and the limiting groove 62 thereon to move downward, and the limiting groove 62 squeezes the adjacent fixed ball 53, and the fixed ball 53 moves from the lowest side of the wave groove of the limiting groove 62 to the highest side of the wave groove (the punching knife 6 rotates 45°). When the fixed ball 53 is located at the highest side of the wave groove, the connecting hole 61 is aligned with the adjacent third passage 52 in the vertical direction. When the punching knife 6 moves downward, it will punch holes in the fabric below it, and it will rotate synchronously during the downward movement, squeezing the fabric while rubbing it, thereby improving the fabric punching efficiency. As the punching knife 6 continues to move downward, the fixed ball 53 slides along the adjacent straight groove on the limiting groove 62 until the fixed ball 53 contacts the highest side of the straight groove on the limiting groove 62, and the punching knife 6 stops moving. At this time, the connecting hole 61 is connected with the lower side of the adjacent third passage 52. When the lower side of the punching knife 6 passes through the fabric, the punching operation is completed.

[0041] When the connecting hole 61 is connected with the lower side of the adjacent third passage 52, the air in the second passage 51 enters the adjacent connecting holes 61 through the four third passages 52 respectively, and enters the punching knife 6 through the four connecting holes 61. The air pressure in the punching knife 6 increases, and the air passing through the punching knife 6 blows off the residual scraps inside it, thereby preventing the punched scraps from entering the punching knife 6 and affecting the subsequent punching operation.

[0042] After completing a punching operation, the control terminal controls the external air pump to close, the gas pressure in the sliding rod 5 is reduced, and the punching knife 6 moves upward under the action of the adjacent spring to push out the gas on its upper side. In the process of pushing out the gas, the gas enters the first passage 41 through the second passage 51, and then the control terminal controls the solenoid valve at the air pump connecting pipe to open, and the gas in the first passage 41 is discharged through the solenoid valve. In the process of the punching knife 6 moving upward, the fixed ball 53 first slides along the straight groove of the limiting groove 62 (at this time, the connecting hole 61 is no longer connected to the adjacent third passage 52), and then the fixed ball 53 slides along the wave groove of the limiting groove 62 (in this process, the punching knife 6 rotates 45° in the opposite direction). When the punching knife 6 is reset upward, the control terminal controls the power output end of the first driving member 3 to be retracted, and drives the sliding rod 5 to move upward. When the sliding rod 5 and the punching knife 6 are reset, the cloth is moved, and the next punching part of the cloth is aligned with the punching knife 6. The above operation is repeated until the punching operation on the cloth is completed.

[0043] The existing punching device fixes the cloth by hand, and even if there is laser assisted positioning, during the punching process, the extrusion force of the punch 6 acts on the cloth. Since the force area at the cloth fixing point is small, the cloth is easily shifted, resulting in inconsistent buttonhole positions, affecting subsequent use.

[0044] Embodiment 2: Based on Embodiment 1, Figure 2-Figure 4 and Fig. 9 As shown, it also includes a second driving member 201, which is composed of a stepping motor and a reduction box. The stepping motor is used to drive the conveyor belt to move forward in stages to facilitate punching holes in the cloth. The second driving member 201 is electrically connected to the control terminal. The second driving member 201 is installed on the front side of the processing bed 1. The processing bed 1 is rotatably connected to two transmission rollers 202. A conveyor belt is wound between the two transmission rollers 202. The conveyor belt is used to drive the other part of the cloth to move to the left to avoid deviation of the front and rear parts of the cloth during the process of punching holes in the cloth, causing wrinkles in the cloth and affecting the punching operation. The second driving member 201 is electrically connected to the control terminal. The second driving member 201 is installed on the front side of the processing bed 1. The processing bed 1 is rotatably connected to two transmission rollers 202. A conveyor belt is wound between the two transmission rollers 202. The conveyor belt is used to drive the other part of the cloth to move to the left to avoid deviation of the front and rear parts of the cloth during the process of punching holes in the cloth, causing wrinkles in the cloth, and affecting the punching operation. The power output end of the component 201 is fixedly connected to the transmission roller 202 on the right side, and a protective shell 203 is fixedly connected to the rear side of the processing bed 1. The protective shell 203 is used to protect the belt and other parts therein. Two rotating shafts 204 are rotatably connected inside the protective shell 203, and a belt is wound around the two rotating shafts 204 through a pulley. The transmission roller 202 on the left side is connected to the adjacent rotating shaft 204 through a transmission device. The transmission device is composed of a pulley, a belt and a gear set, and the transmission ratio of the transmission device is 1:1, which ensures that the moving speed of the belt is consistent with the moving speed of the conveyor belt to avoid wrinkles on the cloth.

[0045] Combination Fig. 9 and Fig.10As shown, the belt between the two rotating shafts 204 is detachably connected with a plurality of evenly distributed first plates 205, and the shell controls the spacing between two adjacent first plates 205 according to the spacing between two adjacent holes required to be punched on the actual cloth, so that the spacing between two adjacent holes is consistent with the spacing between two adjacent first plates 205, and a through hole is provided in the middle of the first plate 205, which is used for the sliding rod 5 to pass through, and the first plate 205 is slidably connected with the second plate 206, and a through hole is provided in the middle of the second plate 206 for the punching knife 6 to pass through, and a spring is connected between the first plate 205 and the adjacent second plate 206 for driving the adjacent second plate 206 to reset, and the first plate 205 and the adjacent second plate 206 move relative to each other to squeeze and fix the cloth, and the aperture of the through hole of the first plate 205 is smaller than the aperture of the through hole of the second plate 206.

[0046] Combination Figure 9-11 As shown, the processing bed 1 is fixedly connected to a fixed frame 301, and a sliding frame 302 is slidably connected to the right side of the fixed frame 301, and a spring is connected between the two. The spring is used to provide downward pressure for the sliding frame 302, so that the smoothing roller 303 is always close to the cloth. The sliding frame 302 is rotatably connected to the smoothing roller 303, and the right side of the processing bed 1 is rotatably connected to two symmetrically distributed supporting rollers 304. The smoothing roller 303 and the two supporting rollers 304 squeeze each other, so that the cloth is flattened and the cloth is always kept taut.

[0047] Combination Figure 9-11 As shown, the fixed frame 301 is slidably connected to the limiting frame 401, and the left and right sides of the limiting frame 401 are provided with inclined parts, and the distance between the two inclined parts of the limiting frame 401 gradually decreases from top to bottom, the limiting frame 401 is slidably connected to the sliding frame 302, the limiting frame 401 is squeezed and matched with the adjacent second plate 206, the second plate 206 contacts and squeezes the left side of the limiting frame 401, the second plate 206 moves downward and clamps the fabric, the right side of the sliding frame 302 is rotatably connected to the locking rod 402, the lower side of the locking rod 402 is provided with two protrusions, and the right side of the limiting frame 401 A cavity is provided, and the locking rod 402 is limitedly matched with the limit frame 401. The limit frame 401 is threadedly connected with two symmetrically distributed limit nuts 403, and the limit nuts 403 are threadedly matched with the fixing frame 301. When the limit nuts 403 are inserted into the fixing frame 301 and the limit frame 401, the distance between the fixing frame 301 and the limit frame 401 will not change. A support plate 404 is fixedly connected to the side of the processing bed 1 close to the protective shell 203, and the support plate 404 is in contact with the adjacent first plate 205. The support plate 404 is used to support the adjacent first plate 205 to keep the first plate 205 in a horizontal state.

[0048] Combination Figure 3 and Fig.12As shown, the processing bed 1 is fixedly connected with a collecting box 501, and the collecting box 501 is used to collect the scraps after punching. The collecting box 501 is connected with a temporary storage sleeve 502. The central axis of the temporary storage sleeve 502 coincides with the central axis of the fixed sleeve 4, ensuring that the punching knife 6 can smoothly enter the temporary storage sleeve 502 when moving downward. A sensor 503 is installed on the outer side of the temporary storage sleeve 502. The sensor 503 is an existing device, which is used to detect whether the scraps enter the temporary storage sleeve 502. The sensor 503 is electrically connected to the control terminal.

[0049] When using the present invention to punch holes in clothing fabric, firstly, the distance between two adjacent first plates 205 is adjusted according to the spacing of the fabric buttonholes, so that the distance between the two adjacent first plates 205 is the same as the distance between two adjacent holes. After the adjustment, the locking rod 402 is pressed downward, and the locking rod 402 drives the sliding frame 302 to move downward, and the sliding frame 302 drives all the parts thereon to move downward synchronously. When the lower side of the locking rod 402 enters the limiting frame 401, the locking rod 402 is rotated, and the limiting frame 401 and the locking rod 402 are locked. At this time, the limiting frame 401 and the locking rod 402 can be regarded as a whole, and then the limiting nut 403 is rotated to separate it from the fixing frame 301.

[0050] After completing the above preparations, pass the starting position of the cloth through the smoothing roller 303 and the two supporting rollers 304 (the cloth can be a single layer or multiple layers stacked and punched at the same time, and the specific choice is made based on the actual situation), and align the first buttonhole position of the cloth between the adjacent first plate 205 and the adjacent second plate 206 (the first one on the left side of the front), so that the buttonhole position of the cloth is aligned with the through hole of the first plate 205, and the rest of the cloth is laid flat on the transmission belt between the two transmission rollers 202.

[0051] When the cloth enters between the smoothing roller 303 and the two supporting rollers 304, the smoothing roller 303 is squeezed, and the smoothing roller 303 moves upward under pressure, and the spring on it is compressed, and the smoothing roller 303 drives the sliding frame 302 to move upward, and the sliding frame 302 drives the limiting frame 401 to move upward through the locking rod 402. When the cloth is placed between the smoothing roller 303 and the two supporting rollers 304, the limiting frame 401 stops moving, and the limiting nut 403 is rotated downward and made to enter the fixed frame 301, and the distance between the limiting frame 401 and the fixed frame 301 is limited by the limiting nut 403, so that the distance between the limiting frame 401 and the fixed frame 301 will not change, thereby completing the position adjustment of the limiting frame 401.

[0052] When the position adjustment of the limiting frame 401 is completed, the control terminal controls the second driving member 201 to start, and the power output end of the second driving member 201 drives the right transmission roller 202 to rotate, and the right transmission roller 202 drives the conveyor belt thereon to move, and the conveyor belt drives the left transmission roller 202 to rotate, and the left transmission roller 202 drives the left rotating shaft 204 to rotate through the transmission device, and the rotating shaft 204 drives the belt thereon to rotate through the pulley, and the belt drives the right rotating shaft 204 to rotate synchronously, and in the process of the belt moving, it drives the first plate 205 evenly distributed thereon to move, and the first plate 205 drives the adjacent second plate 206 to move, and in this process, the starting part of the dragged cloth moves with the adjacent first plate 205 and the adjacent second plate 206 (hereinafter referred to as the left side of the front part) Taking the first one as an example), as the first plate 205 moves, when the second plate 206 contacts and squeezes the limit frame 401, the second plate 206 moves downward along the inclined surface of the limit frame 401 and compresses the adjacent spring, and the distance between the second plate 206 and the adjacent first plate 205 is shortened. When the second plate 206 contacts the horizontal part of the lower side of the limit frame 401, the second plate 206 stops moving downward and clamps the cloth through the adjacent first plate 205. By making the moving distance of the smoothing roller 303 correspond to the thickness of the cloth, the height of the limit frame 401 is controlled, so that the limit frame 401 applies a suitable squeezing force to the second plate 206 to ensure the clamping force of the second plate 206 and the adjacent first plate 205 on the cloth, thereby ensuring that the two drive the cloth to move.

[0053] After the first group of second plates 206 and the adjacent first plates 205 clamp the fabric, the fabric is released and driven to move to the left by the first group of first plates 205 and the adjacent second plates 206. At the same time, the transmission belt drives the other parts of the fabric to move to the left synchronously. During this process, the subsequent first plates 205 and the adjacent second plates 206 rotate forward and contact the limiting frame 401 in turn, thereby clamping the fabric and fixing it, and determining the position of the buttonhole.

[0054] The cloth continuously squeezes the smoothing roller 303 while moving to the left. Meanwhile, the smoothing roller 303 continuously squeezes the cloth through the adjacent spring to flatten the passing cloth and keep the cloth taut during the punching process to ensure the accuracy of the punching position and avoid wrinkles in the cloth causing the punching position to shift. Meanwhile, the first plate 205 and the adjacent second plate 206 pass through the support plate 404. The support plate 404 provides support for the first plate 205 and the adjacent second plate 206 on its upper side to avoid the first plate 205 and the adjacent second plate 206 from deflecting in the up-and-down direction during the movement, thereby preventing the first plate 205 and the adjacent second plate 206 from causing the cloth to shift.

[0055] In the process of the first plate 205 and the adjacent second plate 206 driving the cloth to move to the left, when the through hole of the first plate 205 is aligned with the punching knife 6 (the second driving member 201 is in an intermittent state and stops working), the control terminal controls the first driving member 3 to start, and the power output end of the first driving member 3 drives the sliding rod 5 to move downward, and repeats the operation steps of punching holes in the cloth in the above embodiment. In the process of punching holes, the contact area between the clamping member and the cloth is increased by clamping the cloth by the first plate 205 and the second plate 206 to ensure the stability of the cloth, and avoid the position of the cloth between the layers being offset when punching holes in the cloth, resulting in inconsistent punching positions.

[0056] When the lower side of the sliding rod 5 contacts and squeezes the cloth, the cloth is further fixed by the squeezing force of the sliding rod 5 to ensure the accuracy of the punching position, ensure the stability of the cloth during the punching process, and prevent the cloth from being squeezed by the punching knife 6 and shifted, resulting in inconsistent buttonhole positions and affecting subsequent use.

[0057] After completing the punching of the cloth, the first plate 205 and the adjacent second plate 206 drive the cloth to continue to move to the left, and when the second plate 206 contacts the inclined surface on the left side of the limiting frame 401, the second plate 206 moves upward along the inclined surface and separates from the cloth. When the cloth is separated from all the first plates 205 and the second plates 206, the cloth will fall to the left side of the present invention, so that the cloth with holes punched can be collected.

[0058] After the cloth is separated from the smoothing roller 303, if the thickness of the cloth is inconsistent with that of the previous cloth, all the above steps need to be repeated, and the relative position of the limiting frame 401 and the fixing frame 301 is adjusted before the punching operation; if the thickness of the cloth is consistent with that of the previous cloth, there is no need to rotate the locking rod 402, and thus there is no need to adjust the relative position of the limiting frame 401 and the fixing frame 301, and the next piece of cloth can be directly placed between the smoothing roller 303 and the two supporting rollers 304, and the above punching process can be repeated later.

[0059] After the present invention has been used for a period of time, the punching blade 6 will be worn due to repeated use, resulting in a decrease in the sharpness of the punching blade 6, which is unable to penetrate the cloth, and the sensor 503 does not sense that there is any scrap falling. The specific solution is as follows:

[0060] The control terminal controls the external air pump to turn off and controls the power output end of the first driving member 3 to move upward. When the sliding rod 5 and the punching knife 6 are reset, the control terminal controls the power output end of the first driving member 3 to move downward and turns on the external air pump, and repeats the punching operation. At the same time, during this process, the control terminal controls the second driving member 201 to stop working, so that the cloth stops moving to the left, ensuring the accuracy of the punching position when the cloth is punched for the second time. At the same time, by punching the cloth for the second time, it is avoided that the cloth continues to move when the punching knife 6 is damaged and cannot penetrate the cloth, resulting in incomplete punching of the cloth, affecting subsequent use, and the punching knife 6 repeats the punching operation. After the operation, when the punching knife 6 penetrates the cloth, the lower side of the punching knife 6 enters the temporary storage sleeve 502. According to the above operation process, the air pressure in the punching knife 6 increases and blows out the scraps inside it. The blown scraps enter the temporary storage sleeve 502 and continue to move downward under the action of the air in the punching knife 6, and finally fall into the collection box 501 below. After the scraps enter the temporary storage sleeve 502, the control terminal senses it through the sensor 503. When the punching operation is completed, the scraps in the collection box 501 can be collected. After completing the punching operation of the cloth, the worn punching knife 6 can be replaced and subsequent punching operations can be carried out.
