The driving device 25 is turned on to drive the protective shell 26 to move to the bottom, so that the protective shell 26 drives the sealing and cutting blade 27 to seal and cut the cloth on the top of the sealing cut 21. During the sealing and cutting process, as the protective shell 26 moves to the bottom, the protective shell 26 drives the protective isolation plate 29 to be squeezed on the top of the workbench 1. As the protective shell 26 continues to move downward, the protective isolation plate 29 is squeezed and retracted to the inside of the slide groove 28 to squeeze the first spring 31 to generate elastic force. When the sealing and cutting blade 27 finishes sealing and cutting and moves upward, the first spring 31 generates elastic force to push the protective isolation plate 29 to pop out from the inside of the slide groove 28, so as to protect and isolate the sealing and cutting blade 27, reduce the problem of cutting injuries to the hands of the staff caused by the sealing and cutting blade 27 during the sealing and cutting process, and effectively improve the safety and efficiency of the staff.
[0025] Further, such as Figure 1-Figure 4 As shown, a fixing plate 41 is fixedly connected to the end of the top plate 24; an electric push rod 42 is fixedly connected to the bottom of the fixing plate 41; an extrusion plate 4 is fixedly connected to the bottom of the electric push rod 42; a guide cavity 43 is opened at the end of the workbench 1; a guide plate 44 is slidably connected inside the guide cavity 43; a guide rod 45 is fixedly connected to the side end of the guide plate 44; a clamping plate 46 is fixedly connected to the end of the guide rod 45; during operation, when it is necessary to seal and cut the cloth, since the material of the cloth is relatively soft, the cloth is moved forward and placed on the surface of the clamping plate 46, and then the electric push rod 42 is opened to drive the guide plate 44 to slide to the bottom, so that the extrusion plate 4 is pressed on the surface of the clamping plate 46, so as to clamp and fix the cloth, thereby reducing the problem of the cloth being offset and sliding during the cutting process by the sealing and cutting blade 27.
[0026] Further, such as Figure 1-Figure 4As shown, a third spring 47 is fixedly connected to the bottom of the guide plate 44, and the other end of the third spring 47 is fixedly connected to the inner wall of the guide cavity 43; during operation, when the cloth is clamped, the electric push rod 42 is opened to push the extrusion plate 4 to continuously slide toward the bottom, so that the extrusion plate 4 squeezes the clamping plate 46 to slide toward the bottom to squeeze the third spring 47 to generate elastic force, so that the extrusion plate 4 squeezes the cloth to slide toward the bottom, thereby stretching the cloth and straightening the cloth, which is convenient for continuous sealing and cutting by the sealing and cutting blade 27.
[0027] Further, such as Figure 1-Figure 4 As shown, a guide groove 51 is provided at the end of the clamping plate 46; a guide block 52 is slidably connected to the end of the guide groove 51, and the end of the guide block 52 is semi-arc-shaped; a pull plate 54 is fixedly connected to the side end of the guide block 52; a second spring 55 is fixedly connected to both ends of the pull plate 54, and the other end of the second spring 55 is fixedly connected to the inner side wall of the clamping plate 46; a push column 53 is fixedly connected to the bottom of the guide block 52; when working, when the extrusion plate 4 slides toward the bottom, the guide block 52 is squeezed, so that the guide The block 52 is subjected to the force to slide toward the side end to squeeze the pull plate 54. When the pull plate 54 slides toward the side end due to the squeezing force, the second spring 55 is pulled to generate elastic force, so that the guide block 52 drives the pushing column 53 to extend and retract to the inside of the guide groove 51. When the cloth sealing and cutting is completed, the squeezing plate 4 is driven to slide upward by opening the electric push rod 42, so that the guide block 52 is ejected by the elastic force generated by the second spring 55, and drives the pushing column 53 to push the cloth involved in the surface of the clamping plate 46 to the outside, so as to achieve a cleaning effect.
[0028] Further, such as Figure 1-Figure 4 As shown, a collecting box 6 is installed at the end of the workbench 1 by bolts and is located at the bottom of the clamping plate 46; during operation, when the sealing and cutting blade 27 finishes sealing and cutting the excess cloth, the electric push rod 42 is opened to drive the extrusion plate 4 to slide upward, so that the guide block 52 is pushed to the side by the elastic force generated by the second spring 55, driving the pushing column 53 to slide to the side, so as to push the fabric out to the bottom and drop it into the collection box 6 for collection, thereby reducing the problem of resource waste.
[0029] Further, such as Figure 1-Figure 4 As shown, the bottom of the workbench 1 is fixedly connected with supporting legs 7, and a plurality of supporting legs 7 are provided; when working, a collecting box 6 is installed at the bottom of the workbench 1 to increase the overall supporting effect of the workbench 1.

The driving device 25 is opened to drive the protective shell 26 to move to the bottom, so that the protective shell 26 drives the sealing and cutting blade 27 to seal and cut the cloth at the top of the sealing cut 21. During the sealing and cutting process, as the protective shell 26 moves to the bottom, the protective shell 26 drives the protective isolation plate 29 to be squeezed on the top of the workbench 1. As the protective shell 26 continues to move downward, the protective isolation plate 29 is squeezed and retracted to the inside of the slide 28 for squeezing. The first spring 31 generates elastic force. When the sealing and cutting blade 27 moves upward after sealing and cutting, the first spring 31 generates elastic force to push the protective isolation plate 29 to pop out from the inside of the slide groove 28, so as to protect and isolate the sealing and cutting blade 27, reduce the problem of cutting injuries to the hands of the staff during the sealing and cutting process, and effectively improve the safety and efficiency of the staff; when it is necessary to seal and cut the cloth, since the cloth is relatively soft, the cloth is moved forward and placed on the surface of the clamping plate 46, and then the electric push rod 42 is turned on to drive the guide plate 44 to slide to the bottom, so that the squeezing plate 4 is squeezed on the surface of the clamping plate 46 to clamp and fix the cloth, reducing the cloth from being injured by the cloth. During the cutting process of the sealing and cutting blade 27, there is a problem of offset and sliding; when the cloth is clamped, the electric push rod 42 is opened to push the extrusion plate 4 to slide continuously toward the bottom, so that the extrusion plate 4 squeezes the clamping plate 46 to slide toward the bottom to squeeze the third spring 47 to generate elastic force, so that the extrusion plate 4 squeezes the cloth to slide toward the bottom to stretch the cloth, so that the cloth is straightened, which is convenient for the continuous sealing and cutting of the sealing and cutting blade 27; when the extrusion plate 4 slides toward the bottom, it squeezes the guide block 52, so that the guide block 52 is forced to slide toward the side end to squeeze the pull plate 54, and when the pull plate 54 is squeezed and slides toward the side end, it pulls the second spring 55 to generate elastic force, so that the guide block 52 drives the push column 53 to retract to the inside of the guide groove 51, and when the cloth When the sealing and cutting is completed, the electric push rod 42 is opened to drive the extrusion plate 4 to slide upward, so that the guide block 52 is pushed out by the elastic force generated by the second spring 55, and the pushing column 53 is driven to push the cloth on the surface of the clamping plate 46 to the outside, so as to achieve a cleaning effect; when the sealing and cutting blade 27 finishes sealing and cutting the excess cloth, the electric push rod 42 is opened to drive the extrusion plate 4 to slide upward, so that the guide block 52 is pushed to the side by the elastic force generated by the second spring 55, and the pushing column 53 is driven to slide to the side, so that the fabric is pushed out to the bottom and falls into the collection box 6 for collection, thereby reducing the problem of resource waste; by installing the collection box 6 at the bottom of the workbench 1, the overall support effect of the workbench 1 is increased.
