Technical Field

[0001] This application relates to the field of garment production technology, specifically to a fabric cutting device used in garment production. Background Technology

[0002] When processing garments, the original fabric wound on the fabric reel needs to be cut to the required length for subsequent processing. Existing fabric cutting devices require operators to manually pull the fabric to the appropriate length before activating the cutting blade. This type of fabric cutting machine has excessively high labor costs. There are also automatic fabric cutting machines available, such as the intelligent fabric cutting device for garment processing disclosed in patent number CN201810402051.5. This device uses the cooperation of a first clamping mechanism and a second clamping mechanism to pull out the fabric, reducing the labor intensity of manually pulling the fabric. However, in actual use, when the fabric ends alternate between the first and second clamping mechanisms, fabric ends are prone to falling off, resulting in a high equipment failure rate. Utility Model Content

[0003] In view of the above problems, this application provides a fabric cutting device for garment production, which can reduce labor costs and has higher equipment stability and a lower failure rate.

[0004] According to one aspect of the embodiments of this application, a fabric cutting device for garment production is provided. A fabric cutting device for garment production includes a mounting bracket. The top of the mounting bracket is sequentially provided with a first support platform, a second support platform, and a third support platform. The top of the first support platform is rotatably equipped with a roll device for winding fabric strips. The top of the second support platform is equipped with a clamping device for holding the fabric strips. The third support platform includes two symmetrically arranged mounting plates. A strip-shaped support frame is provided in the middle of the two mounting plates. One end of the strip-shaped support frame is equipped with a driving device for rotating the strip-shaped support frame. Strip-shaped grooves are formed on opposite sides of the strip-shaped support frame. Mounting grooves are formed on the two inner sidewalls of each strip-shaped groove. A first telescopic component is fixed within the mounting groove. Two extrusion plates are arranged parallel within the mounting groove. The free end of the first telescopic component extends into the mounting groove and connects to the opposite side of the two extrusion plates. The tops of the two mounting plates are connected to a lifting platform via a vertically arranged second telescopic component. A strip-shaped extrusion protrusion is provided at the bottom of the lifting platform. A cutting component is provided on one side of the extrusion protrusion at the bottom of the lifting platform.

[0005] In some embodiments, the top of the extrusion protrusion is connected to the bottom of the lifting platform by a plurality of elastic elements, and the bottom of the extrusion protrusion is lower than the bottom of the cutting component.

[0006] In some embodiments, the cutting component includes a cutting blade, a strip-shaped hole is provided at the lifting platform, a vertical plate is connected to the top of the cutting blade, the vertical plate extends upward through the strip-shaped hole, and a first limiting slide rail and a second limiting slide rail are respectively provided on the outer side wall of the vertical plate on the upper and lower sides of the lifting platform, the first limiting slide rail and the second limiting slide rail abut against the upper and lower sides of the lifting platform respectively.

[0007] In some embodiments, one end of the vertical plate is connected to the inner wall of the strip hole by a spring, and a notch is provided at the top of the vertical plate. A cam corresponding to the notch is connected to the lifting platform by a cutting motor.

[0008] In some embodiments, a triangular-section groove is formed on the outer wall of the strip support frame on one side of the strip groove.

[0009] In some embodiments, a belt conveyor is provided on the mounting support, and the belt conveyor is located below the strip support frame.

[0010] The beneficial effects of this application are as follows: By setting up a strip support frame to pull the fabric strip, the fabric strip is tightly wrapped around the outer perimeter of the strip support frame.

Figure 6This is a partial structural diagram of the cutting component provided in an embodiment of this application. The fabric cutting device 100 applied to garment production includes a mounting bracket. A first support platform 110, a second support platform 120, and a third support platform 130 are sequentially arranged on the top of the mounting bracket. The first support platform 110, the second support platform 120, and the third support platform 130 are located on the same straight line and are used to support and mount each component. They can be an integral structure with the mounting bracket. A roll device 111 for winding fabric strips is rotatably provided on the top of the first support platform 110. The fabric strip to be cut is wound around the roll device 111. A clamping device 121 for clamping the fabric strip is provided on the top of the second support platform 120. After the fabric strip on the roll device 111 is pulled and passes through the clamping device 121, the clamping device 121 provides a certain frictional force to clamp the fabric strip, so that the fabric strip can be kept taut when the strip support frame 140 pulls the fabric strip subsequently. The clamping device 121 can be configured with reference to existing technology. The third support platform 130 includes two symmetrically arranged mounting plates 131. A strip support frame 140 is jointly arranged in the middle of the two mounting plates 131. The cross-section of the strip support frame 140 can be square, and the material of the strip support frame 140 can be aluminum alloy or metal. One end of the strip support frame 140 is provided with a drive device 132 for driving the strip support frame 140 to rotate. The drive device 132 can be a motor or other forms. Strip grooves 141 are respectively opened on the two opposite sides of the strip support frame 140. Mounting grooves 142 are opened on the two inner side walls of the strip grooves 141. A first telescopic component 143 is fixed in the mounting groove 142. Two extrusion plates 144 are arranged in parallel in the mounting groove 142. The free end of the first telescopic component 143 extends into the mounting groove 142 and connects to the opposite side of the two extrusion plates 144. The first telescopic component 143 can be an electric telescopic rod, and its power source can be a battery. The battery will be placed inside the strip support frame 140. The tops of the two mounting plates 131 are connected to a lifting platform 150 via a vertically arranged second telescopic component 151. The bottom of the lifting platform 150 is provided with a strip-shaped extrusion protrusion 160. A cutting component 170 is provided on one side of the extrusion protrusion 160 at the bottom of the lifting platform 150. During the descent of the lifting platform 150, the extrusion protrusion and the cutting component 170 will move down together. The extrusion protrusion 160 is used to press the fabric strip into the strip groove 141, and the cutting component 170 is used to cut the fabric strip.

[0023] In this embodiment, during operation, the strip of fabric wound on the rolling device 111 is pulled through the pressing device 121 and clamped at one end between the two pressing plates 144 in one of the mounting slots 142. Then, the driving device 132 is turned on, and the driving device 132 drives the strip support frame 140 to rotate 180°. During this process, due to the friction of the pressing device 121 on the strip of fabric, the strip of fabric will be tightened and wrapped around the strip support frame 140 for one and a half turns. Then, the second telescopic component 151 drives the lifting platform 150 to fall. Simultaneously, the pressing protrusion 160 will fall and... The fabric strip is pressed into another mounting groove 142. In this mounting groove 142, the first telescopic component 143 drives the pressing plate 144 to move towards each other and clamp the fabric strip again. Then the cutting component 170 completes the cutting of the fabric strip. Simultaneously, the two pressing plates 144 in the lower mounting groove 142 are reset under the action of the first telescopic component 143 and no longer clamp the fabric end. The cut fabric end will fall naturally under the action of gravity. Then the second telescopic component 151 is reset, and the driving device 132 drives the strip support frame 140 to rotate 180° again. The fabric strip can be continuously cut in this cycle.

[0024] As can be seen from the above, in this embodiment, a strip support frame 140 is set up to pull the fabric strip. After the fabric strip is taut, it is wrapped around the outer periphery of the strip support frame 140. The length of the cut fabric strip can be controlled by controlling the perimeter of the strip support frame 140. Compared with measurement methods such as infrared rangefinders, it is less affected by external interference and the measurement is more accurate, making it easier to control the length of the cut fabric strips to be consistent. In this embodiment, a lifting platform 150 is also connected to the cutting component 170 and the extrusion protrusion 160. The extrusion protrusion 160 cooperates with the extrusion plate 144 inside the strip groove 141 of the strip support frame 140. Before cutting the fabric strip, the extrusion protrusion 160 can press the fabric strip into the strip groove 141 during the downward movement. Subsequently, the extrusion plate 144 completes the clamping of the fabric strip. Finally, the cutting component 170 completes the cutting of the fabric strip. The cutting process clamps first and then cuts, the working process is stable, and the scrap rate caused by equipment failure is low.

[0025] In some embodiments, the top of the extrusion protrusion 160 is connected to the bottom of the lifting platform 150 via multiple elastic members 161, and the bottom height of the extrusion protrusion 160 is lower than the bottom height of the cutting member 170. In this embodiment, with the above-mentioned arrangement, the bottom height of the extrusion protrusion 160 is lower than the bottom height of the cutting member 170, so the extrusion protrusion 160 will contact the fabric strip above the strip support frame 140 before the cutting member 170 and press the fabric strip into the strip groove 141. After the extrusion protrusion 160 moves to the bottom of the strip groove, the elastic members 161 will be compressed, and the lifting platform 150 can continue to press down, thereby ensuring that the cutting member 170 can always stick to the fabric strip to complete the cutting.

[0026] In some embodiments, the cutting component 170 includes a cutting blade 171, a strip-shaped hole 152 is provided at the lifting platform 150, a vertical plate 172 is connected to the top of the cutting blade 171, the vertical plate 172 extends upward through the strip-shaped hole 152, and a first limiting slide rail 173 and a second limiting slide rail 174 are respectively provided on the upper and lower sides of the lifting platform 150 on the outer side of the vertical plate 172. The first limiting slide rail 173 and the second limiting slide rail 174 abut against the upper and lower sides of the lifting platform 150 respectively. This application embodiment provides a specific arrangement of the cutting component 170. Under the restriction of the first limiting slide rail 173 and the second limiting slide rail 174, the vertical displacement of the cutting blade 171 relative to the lifting platform 150 will be restricted, thereby preventing the cutting blade 171 from falling off.

[0027] In some embodiments, one end of the vertical plate 172 is connected to the inner wall of the strip hole 152 via a spring 153. A notch 172a is provided at the top of the vertical plate 172. A cam 154 corresponding to the notch 172a is connected to the lifting platform 150 via a cutting motor. In this embodiment, with the above configuration, when the lifting platform 150 moves to the lowest end, the cutting blade 171 will press the fabric strip, and the cutting motor will drive the cam 154 to rotate. The free end of the cam 154 pushes the vertical plate 172 and the cutting blade 171 to move horizontally under the limitation of the strip hole 152 through the notch 172a. After the cam 154 slides past the notch 172a, the vertical plate 172 returns to its original position under the action of the spring 153, thereby ensuring that the fabric strip is cut neatly.

[0028] In some embodiments, a triangular-section cutting groove 145 is formed on one side of the strip groove 141 on the outer wall of the strip support frame 140. In this embodiment, with the above arrangement, the cutting blade 171 will preferentially press the fabric strip into the cutting groove 145 before cutting, ensuring stability during the cutting process.

[0029] In some embodiments, a belt conveyor 180 is provided on the mounting support, and the belt conveyor 180 is located below the strip support frame 140. In this embodiment, with the above arrangement, after the fabric strip is cut, it will slide down to the top of the belt conveyor under the action of gravity, and then be transported by the belt conveyor to the next process.
