Description

Technical Field

[0001] The invention relates to the technical field of clothing production, and in particular to a proofing device for clothing production. Background Art

[0002] The modern clothing production process includes design, procurement, pre-processing, proofing, sewing and quality inspection. In the clothing production process, machine processing is generally used as the main method and manual processing as the auxiliary method. Among them, proofing (i.e. marking and cutting) is usually completed by a proofing machine. The staff inputs the corresponding data into the terminal of the proofing machine, so that the proofing machine draws the shape of the fabric to be cut on the sample paper, and then uses a cutting knife to cut the fabric to complete the proofing work.

[0003] During the use of the cutting knives, the blade will gradually wear, resulting in increased resistance between the cutting knives and the fabric. Since the existing proofing device lacks a detection mechanism for the tool status, the tool will continue to be used after it is worn, causing the following problems to easily occur during the use of the proofing machine: the worn cutting knives cannot provide a clean and sharp cutting edge, resulting in rough or uneven edges of the fabric. At the same time, during the cutting process, the worn cutting knives will cause the fabric to move, causing an offset between the fabric and the sample paper, affecting the accuracy of subsequent processes, and thus affecting the normal progress of clothing production.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0021] A proofing device for garment production, such as Figure 1-Figure 7 As shown, it includes: a support platform 1; a feeding roller 2, which is arranged on the support platform 1, and the support platform 1 is provided with an electric slide rail; a sliding frame 3, which is slidably connected to the electric slide rail of the support platform 1 through an electric slider, and the sliding frame 3 is slidably connected to a moving frame 4, and a driving module for driving it to move is arranged in the moving frame 4; a lifting motor 5, which is fixed to the moving frame 4, and the output shaft of the lifting motor 5 is fixedly connected to a lead screw 6, and the lead screw 6 is rotatably connected to the moving frame 4; a rotating frame 7, which is threadedly connected to the lead screw 6, and the rotating frame 7 is slidably connected to the moving frame 4; an adjusting shell 8, which is rotatably connected to the rotating frame 7; a connecting shell 9, which is slidably connected to the adjusting shell 8, and the connecting shell 9 is spline-connected with a cutting knife 10, and a first tension spring 11 is fixedly connected between the two; an adjusting mechanism, which is arranged on the connecting shell 9, and is used to control the movement of the cutting knife 10 after the resistance it encounters increases; a rotating component, which is arranged on the rotating frame 7, and is used to drive the adjusting shell 8 to rotate.

[0022] The above scheme provides a method for checking the wear of the tool and separating the tool from the cloth when the tool is severely worn; the support table 1 is provided with a control terminal for controlling the movement of all electrical components below, and a conveyor belt is provided on the support table 1, and the conveyor belt is used to drive the cloth to move; the electric slide rail of the support table 1 is used to drive the sliding frame 3 to move forward and backward, and the driving module of the mobile frame 4 is used to drive it to move left and right; the mobile frame 4 is provided with a marking device not shown, which is an existing device and its use method will not be described in detail. The marking device is used to draw the shape of the cloth to be cut on the sample paper, and the screw 6 is used to drive the rotating frame 7 The movable frame 4 moves up and down and is used to limit the position of the rotating frame 7 to prevent the rotating frame 7 from rotating on its own; the adjusting shell 8 is provided with an elliptical groove, and the connecting shell 9 is located in the elliptical groove of the adjusting shell 8 and slides. Initially, the central axis of the connecting shell 9 is coaxial with the central axis of the adjusting shell 8; the cutting knife 10 is an existing device and is not described in detail. Its specific shape can be adjusted according to actual use. Initially, the first tension spring 11 in the connecting shell 9 is in a stretched state, which is used to provide the cutting knife 10 with a force to move upward; the adjusting mechanism is used to fix the position of the cutting knife 10, and the rotating assembly is used to drive the adjusting shell 8 to rotate and adjust the angle of the cutting knife 10.

[0023] Further, such as Figure 5-Figure 7 As shown, the adjustment mechanism includes: a sealing ring 12, which is slidably connected to the connecting shell 9, the connecting shell 9 is provided with a sliding cavity 901, the connecting shell 9 is provided with an exhaust hole connected to the sliding cavity 901, and the sealing ring 12 is used to block the exhaust hole of the connecting shell 9; a sealing plate 13, which is fixed to the cutting knife 10, the sealing plate 13 is slidably connected to the connecting shell 9, and the sealing plate 13 is located in the sliding cavity 901, and a first spring 14 is fixed between the connecting shell 9 and the sealing ring 12; a limiting assembly, which is arranged on the adjusting shell 8, and is used to limit the movement of the sealing ring 12.

[0024] The above scheme provides a way to separate the tool from the cloth when the tool is severely worn; the sealing ring 12 is in contact with the adjusting shell 8, and the exhaust hole of the connecting shell 9 is used to discharge the gas in the sliding cavity 901 thereon; the sealing plate 13 is used to push the gas in the sliding cavity 901 to move, and a rubber ring may be provided on the edge of the sealing plate 13 to increase the sealing between the sealing plate 13 and the connecting shell 9. Initially, the first spring 14 is in a compressed state, and the first spring 14 is used to provide a downward thrust for the sealing ring 12.

[0025] Further, such as Figure 5 As shown, the limiting assembly includes: a limiting rod 15, which is slidably connected to the adjusting shell 8, a second spring 16 is fixedly connected between the limiting rod 15 and the adjusting shell 8, and the sealing ring 12 is provided with a limiting hole, and the limiting rod 15 limits the position of the sealing ring 12 through the limiting hole of the sealing ring 12.

[0026] The above scheme provides a method for limiting the movement of the sealing ring 12; the limiting rod 15 is hemispherical, which is convenient for it to enter the limiting hole of the sealing ring 12. Initially, the second spring 16 on the limiting rod 15 is in a force storage state, and the depth of the upper limiting hole of the sealing ring 12 is smaller than the radius of the upper hemisphere of the limiting rod 15, so that the sealing ring 12 can directly squeeze the limiting rod 15 into the limiting hole thereon.

[0027] Further, such as Figure 2-Figure 4 As shown, the rotating assembly includes: a rotating motor 17, which is fixed to the rotating frame 7, and the output shaft of the rotating motor 17 is rotatably connected to the rotating frame 7; a first gear 18, which is fixed to the output shaft of the rotating motor 17; and a second gear 19, which is fixed to the adjusting housing 8, and the second gear 19 is meshed with the first gear 18.

[0028] The above scheme provides a method for adjusting the angle of the cutting knife 10; the number of teeth of the first gear 18 is smaller than the number of teeth of the second gear 19, which is used to reduce the transmission ratio between the two and to increase the stability when the second gear 19 drives the adjusting shell 8 to rotate, thereby facilitating the adjustment of the angle of the cutting knife 10.

[0029] Workflow: When it is necessary to proofread the fabric, the staff starts the feeding roller 2 through the control terminal, releases the fabric on the feeding roller 2 and places it on the support table 1, flattens the fabric and places the sample paper on the upper side of the fabric, and then fixes the edges of the fabric and the sample paper through the existing device (for the convenience of expression, the fabric is only referred to as fabric below). After the fabric is fixed, the staff inputs the shape of the fabric to be cut into the control terminal, and then controls the electrical components in the control device of the terminal to move, the electric slide rail on the support table 1 drives the sliding frame 3 to move forward and backward, and the driving module in the moving frame 4 drives it to move left and right. During this process, the marking device is started and The shape of the cloth to be cut is drawn on the sample paper. After the sample paper is marked, the movable frame 4 and the sliding frame 3 are reset and stop moving. The control terminal starts the lifting motor 5. The output shaft of the lifting motor 5 drives the rotating frame 7 to move downward through the screw 6. The rotating frame 7 drives the cutting knife 10 to move downward through the adjusting shell 8 and the connecting shell 9. After the cutting knife 10 moves to a suitable position (that is, the position where the cutting knife 10 can cut the cloth and the sample paper), the lifting motor 5 is turned off, and the sliding frame 3 and the movable frame 4 drive the cutting knife 10 to move to cut the cloth. In this process, the limiting rod 15 limits the sealing ring 12, so that the connecting shell 9 will not move relative to the adjusting shell 8.

[0030] In the process of the above-mentioned cutting knife 10 cutting the cloth, when the angle of the cutting knife 10 needs to be adjusted, the control terminal starts the rotating motor 17, and the output shaft of the rotating motor 17 drives the second gear 19 to rotate through the first gear 18, so that the second gear 19 drives the cutting knife 10 to rotate through the adjustment shell 8 and the connecting shell 9, thereby adjusting the angle of the cutting knife 10 so that the direction of the cutting knife 10 corresponds to the cutting direction of the cloth.

[0031] As the cutting knife 10 gradually cuts the cloth, after the cutting knife 10 is worn, the following text will refer to the cutting knife 10 moving backward, and the resistance encountered by the cutting knife 10 when cutting the cloth gradually increases. When the resistance of the cloth to the cutting knife 10 is greater than the limiting force of the limiting rod 15 on the sealing ring 12, the connecting shell 9 moves forward relative to the adjusting shell 8, and the sealing ring 12 moves forward relative to the limiting rod 15, so that the limiting rod 15 is separated from the limiting hole of the sealing ring 12 and compresses the adjacent second spring 16, until the limiting rod 15 is separated from the sealing ring 12, the limiting rod 15 releases the limiting of the sealing ring 12, and the sealing ring 12 moves downward under the thrust of the adjacent first spring 14. When the sealing ring 12 is separated from the exhaust hole on the connecting shell 9, the sealing ring 12 is released. To seal the exhaust hole on the sliding chamber 901, the first tension spring 11 in the connecting shell 9 drives the cutting knife 10 to move upward, and the cutting knife 10 drives the sealing plate 13 to move upward. The sealing plate 13 squeezes the gas in the sliding chamber 901, and the gas is discharged from the exhaust hole of the connecting shell 9. At the same time, the cutting knife 10 is separated from the cloth to prevent the cutting knife 10 from continuing to cut the cloth after being severely worn, resulting in uneven edges of the cloth and affecting the subsequent normal use of the cloth. After the first tension spring 11 stops shrinking, the cutting knife 10 stops moving, and the staff replaces the cutting knife 10 and repeats the above reverse process to reset the device, so that the first tension spring 11 is stretched and reset again, and at the same time, the sealing ring 12 seals the exhaust hole on the sliding chamber 901 again, and then continues to cut the cloth.

[0032] Further, such as Figure 3-Figure 6 , Figure 8 and Fig. 9 As shown, it also includes: a fixing component, which has two components, both of which are arranged on the adjusting shell 8, and are used to fix the cloth cutting position, and the fixing component includes: a connecting frame 20, which is fixed to the adjusting shell 8; a first arc frame 21, which is fixed to the connecting frame 20, and the first arc frame 21 is slidably connected to the first guide frame 22; a second arc frame 23, which is fixed to the connecting frame 20, and the second arc frame 23 is slidably connected to the second guide frame 24, and the first guide frame 22 and the second guide frame 24 are rotatably connected to the fixed material roller 25, and the fixed material roller 25 is used to squeeze the cloth; a pushing component, which is arranged on the sealing ring 12, and is used to adjust the angle of the fixed material roller 25.

[0033] Further, such as Figure 8 and Fig. 9 As shown, the diameter of the metering roller 25 gradually increases as the distance between the metering roller 25 and the cutting blade 10 gradually increases.

[0034] Further, such as Figure 3 , Figure 8 and Fig. 9 As shown, the radius of the circle corresponding to the first arc frame 21 is smaller than the radius of the circle corresponding to the second arc frame 23, and the central axes of the two corresponding circles are coaxial.

[0035] The above scheme provides a method for fixing the cut edge of the cloth during the process of cutting the cloth; the two connecting frames 20 are respectively located on the left and right sides of the adjustment shell 8, and the initial position is referenced Figure 3 As shown; the second arc frame 23 and the second guide frame 24 are both composed of a round rod and an arc plate, and the two arc plates are used to limit the positions of the second arc frame 23 and the second guide frame 24 respectively. The fixed material roller 25 is made of rubber and is used to reduce the degree of squeezing of the cloth by the fixed material roller 25 to prevent the cloth from being deformed due to excessive squeezing, which affects the normal use of the cloth. The fixed material roller 25 is used to fix the cutting edge of the cloth. The diameter of the left side of the fixed material roller 25 is greater than the diameter of the right side thereof (reference Fig. 9 As shown in the figure, during the process of the cutting knife 10 cutting the cloth, the fixed material roller 25 rotates along the surface of the cloth, so as to reduce the friction between the fixed material roller 25 and the cloth during the movement.

[0036] Further, such as Figure 4 , Figure 8 and Fig. 9 As shown, the pusher assembly includes: an extrusion plate 26 fixed to the sealing ring 12; a transmission rod 27 fixed to the second guide frame 24, the transmission rod 27 is in extrusion contact with the extrusion plate 26, and a second tension spring 28 is provided between the second guide frame 24 and the second arc frame 23.

[0037] Further, such as Figure 4 , Figure 8 and Fig. 9 As shown, the angle between the extension line of the upper axis of the transmission rod 27 and the horizontal plane is greater than the angle between the lower side of the dosing roller 25 and the horizontal plane.

[0038] After the cutter is worn, as the cutter moves, the cloth will accumulate on the upper side of the cutter, and the accumulated cloth is not in sufficient contact with the cutter. As the cutter moves upward, the cutter cannot quickly cut the cloth completely, causing the cutter to easily move the cloth. The following solutions are provided: The extrusion plate 26 is used to push the transmission rod 27 to move downward. The degree of the central angle corresponding to the arc plate on the second guide frame 24 is greater than half of the degree of the central angle corresponding to the second arc frame 23, so that the second guide frame 24 has sufficient space to move. The second tension spring 28 is located between the upper part of the second guide frame 24 and the upper part of the second arc frame 23. Initially, the second tension spring 28 on the second guide frame 24 is initially in a stretched state, which is used to maintain the stability of the second guide frame 24. The extrusion plate 26 is provided with a U-shaped groove. The U-shaped groove of the extrusion plate 26 is used to limit the position of the transmission rod 27. The angle difference between the transmission rod 27 and the fixed material roller 25 and the horizontal plane is used to make the lower side of the fixed material roller 25 fit with the cloth after rotating, thereby increasing the contact area between the fixed material roller 25 and the cloth, thereby increasing the fixing force of the fixed material roller 25 on the cloth.

[0039] Working process: in the process of the above-mentioned rotating frame 7 moving downward, the adjusting shell 8 drives the first arc frame 21 and the second arc frame 23 to move downward through the connecting frame 20, and the first arc frame 21 and the second arc frame 23 respectively drive the fixing roller 25 to move downward through the first guide frame 22 and the second guide frame 24, until the rotating frame 7 stops moving, the connecting frame 20 and the parts thereon all stop moving, at this time the fixing roller 25 is in contact with the surface of the cloth (the position where the diameter of the fixing roller 25 is larger), the cutting position of the cloth is fixed, and the cutting position of the cloth is prevented from moving during the cutting process, resulting in uneven edges of the cloth, affecting the normal use of the cloth, and in the process of the cutting knife 10 cutting the cloth, the fixing roller 25 rotates along the surface of the cloth, reducing the friction between the fixing roller 25 and the cloth, thereby preventing the fixing roller 25 from driving the cloth to move, causing the cloth and the sample paper to be misaligned, affecting the accuracy of cloth proofing.

[0040] In the process of the second gear 19 driving the adjusting shell 8 to rotate, the adjusting shell 8 drives the connecting frame 20 and the parts thereon to rotate synchronously, so that the two fixing rollers 25 are always located on both sides of the moving direction of the cutting knife 10, so that the two fixing rollers 25 can always fix the edge of the cloth being cut.

[0041] In the process that the first spring 14 pushes the sealing ring 12 to move downward, the sealing ring 12 drives the extrusion plate 26 to move downward. Taking the moving direction of the left extrusion plate 26 and its adjacent parts as an example, the extrusion plate 26 presses the transmission rod 27 downward, and the transmission rod 27 drives the second guide frame 24 to rotate clockwise along the second arc frame 23 (viewed from front to back), and the second guide frame 24 swings clockwise ( Fig. 9 Looking from the front to the back, the adjacent second tension spring 28 is stretched (swinging downward), and at the same time, the second guide frame 24 drives the dosing roller 25 to swing synchronously, and the dosing roller 25 drives the first guide frame 22 to swing clockwise (swinging upward), and the area with a larger diameter of the dosing roller 25 rotates clockwise ( Fig. 9 Looking from the front to the back), the dosing roller 25 exerts a force on the adjacent cloth to move to the left, and the cloth in the cutting area is stretched and away from the cutting knife 10 (the cutting knife 10 has not moved upward at this time), and the amount of cloth accumulated on the upper side of the cutting knife 10 is reduced, so that the cloth contacts the cutting knife, thereby facilitating the cutting knife 10 to move upward to cut the cloth, reducing the tendency of the cutting knife 10 to drive the cloth to move upward, until the sealing ring 12 stops moving downward, the second guide frame 24 stops rotating, and the dosing roller 25 stops rotating. At this time, the side surface (gradient surface) of the dosing roller 25 is in contact with the cloth, completing the final fixation of the cloth, and then the cutting knife 10 is replaced, and the above reverse process is repeated after the replacement of the cutting knife 10 is completed to reset the device.

[0042] Further, such as Figure 5-Figure 7As shown, it also includes: a sliding mechanism, which is arranged on the adjusting shell 8 and is used to drive the connecting shell 9 to move in the opposite direction. The sliding mechanism includes: a guide ring 29, which is slidably connected to the adjusting shell 8, the guide ring 29 is fixedly connected to the connecting shell 9, and a third tension spring 30 is arranged between the guide ring 29 and the adjusting shell 8.

[0043] The above scheme provides a method for driving the tool to move in the opposite direction when the tool is separated from the cloth; the guide ring 29 is used to drive the connecting shell 9 to move in the opposite direction, so that the cutting knife 10 is separated from the cutting position of the cloth. Initially, the third tension spring 30 on the guide ring 29 is in a stretched state, providing power for the guide ring 29 to move to the side away from the movable frame 4.

[0044] Working process: In the process of the above-mentioned cutting knife 10 cutting the cloth, taking the cutting knife 10 moving backward as an example, as the degree of wear of the cutting knife 10 gradually increases, the resistance encountered by the cutting knife 10 gradually increases. When the limiting force of the limiting rod 15 on the sealing ring 12 is less than the sum of the resistance of the cloth to the cutting knife 10 and the limiting force of the third tension spring 30 on the guide ring 29, the limiting rod 15 releases the limiting force on the sealing ring 12, and the third tension spring 30 pushes the connecting shell 9 forward through the guide ring 29, and the connecting shell 9 drives the parts thereon to move forward, so that the cutting knife 10 is separated from the cloth accumulation place, so as to avoid the cutting knife 10 moving upward at the cloth accumulation place, and the cutting knife 10 drives the cloth to move upward, causing damage to the cloth and affecting its subsequent normal use. After that, the staff replaces the cutting knife 10 and resets the device.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
