Description

TECHNICAL FIELD

[0001] The utility model relates to the field of patchwork embroidery cutting, especially to a cutting device for patchwork embroidery. BACKGROUND

[0002] "Cutting" in patchwork embroidery refers to the process of cutting fabric during production. This process is very important for patchwork embroidery as it helps to form the patterns and shapes of the final work.

[0003] According to the cloth cutting device disclosed in Chinese patent CN218643034U, one of the problems mentioned is that the fabric will spread to both sides during the cutting process, affecting the cutting quality. The solution of this device is to press the fabric down with a press wheel to make the cutting more stable. Although the design of the press wheel can solve this problem to some extent, manual intervention is still needed to ensure the accuracy of the cutting. Moreover, when cutting fabrics of different sizes, the horizontal and transverse moving assemblies need to be adjusted manually to adapt to different size requirements. However, this method is time-consuming and prone to human error.

[0004] Therefore, we propose a cutting device for patchwork embroidery that can automatically adjust the cutting size. SUMMARY

[0005] To overcome the shortcomings of operators needing to use a ruler or tape measure to measure the fabric size to ensure cutting accuracy, and manual measurement may lead to cumulative errors, especially when cutting a large number of fabrics of the same size, which may affect the quality of the work, the utility model provides a cutting device for patchwork embroidery that can automatically adjust the cutting size.

[0024] like Figure 1 and Figure 5As shown, the clamping mechanism comprises: electric sliding rail Ⅰ3, sliding block Ⅰ31 and clamp block 32, the top front side of the outer frame 1 is fixedly installed with electric sliding rail Ⅰ3 in a left and right distributed manner, and the electric sliding rail Ⅰ3 is vertically arranged, so that the sliding block Ⅰ31 can move up and down, and the sliding block Ⅰ31 is slidably connected to the electric sliding rail Ⅰ3, and the clamp block 32 is welded between the two sliding blocks Ⅰ31.

[0025] As shown in Figure 1 and Figure 3 The cutting mechanism comprises: electric sliding rail Ⅱ4, sliding block Ⅱ41, air cylinder 42, electric sliding rail Ⅲ43 and laser cutting machine 44, the top of the conveying belt 21 is fixedly installed with electric sliding rail Ⅱ4 at both ends, and the electric sliding rail Ⅱ4 is horizontally arranged, so that the sliding block Ⅱ41 can move left and right, and the sliding block Ⅱ41 is slidably connected to the electric sliding rail Ⅱ4, and the air cylinder 42 is fixedly installed at the top of the sliding block Ⅱ41, and the electric sliding rail Ⅲ43 is fixedly connected between the piston rods of the two air cylinders 42, for driving the electric sliding rail Ⅲ43 to move up and down, and the laser cutting machine 44 is slidably installed on the electric sliding rail Ⅲ43, for cutting the cloth.

[0026] As shown in Figure 3 and Figure 4 The flattening mechanism comprises: connecting rod 5, fixed rod 51, spring 52, pressing block 53 and pressing wheel 54, the connecting rod 5 is slidably connected to the electric sliding rail Ⅲ43 at the front middle position in a left and right distributed manner, the fixed rod 51 is welded to the rear side of the connecting rod 5, the spring 52 is arranged around the fixed rod 51, the spring 52 is located between the bottom of the electric sliding rail Ⅲ43 and the lower part of the fixed rod 51, the pressing block 53 is fixedly connected between the bottoms of the connecting rods 5 on the two sides, and the pressing wheel 54 is rotatably connected to the bottom of the pressing block 53 in an embedded manner, so that the pressing wheel 54 can slide while smoothing the wrinkles of the cloth.

[0027] As shown in Figure 1 It also comprises a measuring panel 7, and the right part of the right electric sliding rail Ⅱ4 is provided with the measuring panel 7, for measuring the length of the cloth to be cut.

[0028] When the operator uses the device to cut the embroidered cloth, first, the cloth to be cut is sleeved on the cloth hanging frame 24, and then the cloth is pulled out and inserted into the gap at the bottom of the conveying shaft 23, and after ensuring that the conveying shaft 23 presses the cloth, the motor 2 is started through the controller 6, the motor 2 drives the conveying belt 21 to operate, at this time the conveying belt 21 conveys the cloth to the lower side of the clamp block 32, then the motor 2 is turned off, and the conveying belt 21 stops operating, then the electric sliding rail Ⅰ3 is started through the controller 6, at this time the sliding block Ⅰ31 drives the clamp block 32 to slide downward to press the cloth, and after ensuring that the cloth is pressed, the electric sliding rail Ⅰ3 is turned off.

[0029] When the cloth needs to be smoothed, the controller 6 is started again to start the air cylinder 42, the piston rod of the air cylinder 42 drives the electric sliding rail III 43 to move downward, and the pressing block 53 is driven to move downward to press the cloth. When the cloth to be cut is thicker, the spring 52 will be compressed during the downward movement of the pressing block 53, so as to increase the pressure on the thicker cloth, so that the cloth can be better pressed. After completion, the air cylinder 42 is closed, and then the controller 6 is started again to start the electric sliding rail II 4. At this time, the sliding block II 41 will drive the pressing block 53 to slide to the rear side on the electric sliding rail II 4. At the same time of sliding, the pressing wheel 54 will smooth the wrinkles of the cloth to prevent the wrinkles from causing errors in the cutting length of the cloth. At the same time, the data on the visual measurement panel 7 is measured to measure the required cutting length. When the required cutting length is reached, the electric sliding rail II 4 is immediately closed. At this time, the electric sliding rail II 4 and the pressing block 53 stop at the position of the required cutting length. Then the controller 6 is started again to start the laser cutting machine 44 and the electric sliding rail III 43. The laser cutting machine 44 will move on the electric sliding rail III 43 and cut the cloth at the same time. After the cutting is completed, the electric sliding rail III 43 and the laser cutting machine 44 are closed, and the cloth with the required cutting length can be obtained. If it needs to be cut again, the above operation can be repeated.
