DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 4 The embodiment of the present application provides a precise trimming device for processing polyester grey cloth, including a frame 1, on which a reel 2 and a reel 3 are installed, both of which are devices for pulling the grey cloth to move in the prior art, a bidirectional threaded rod 4 is rotatably connected to the frame 1, two sliding frames 5 are slidably connected to the frame 1, the two sliding frames 5 are arranged opposite to each other and are both threadedly connected to the bidirectional threaded rod 4, a moving block 6 is slidably connected to the sliding frame 5, a plurality of extrusion wheel grooves 7 are provided at the bottom of the moving block 6, and a spring is installed in the extrusion wheel groove 7 8. An extrusion block 9 is slidably connected in the extrusion wheel groove 7, and an extrusion wheel 10 is rotatably connected to the extrusion block 9. A dividing groove 11 is provided on the sliding frame 5, and the extrusion wheels 10 are evenly distributed on both sides of the dividing groove 11. A cutting device is provided on the moving block 6, and the cutting device is located directly above the dividing groove 11. A limiting groove 12 is provided on the top of the moving block 6, and the same limiting plate 13 is slidably connected in the two limiting grooves 12. A linear actuator 14 is installed on the frame 1, and the linear actuator 14 can be an electric cylinder. The output end of the linear actuator 14 is connected to the limiting plate 13.

[0022] In this embodiment, the untrimmed grey cloth is pulled by the unwinding roller 2 and the winding roller 3 to move, and the two-way threaded rod 4 is rotated to drive the two sliding frames 5 to move in opposite directions, so that when the grey cloth is pulled, the cutting line that needs to be trimmed slides over the dividing groove 11 on the sliding frame 5, thereby being suitable for trimming grey cloth with different width requirements. By extending the output end of the linear actuator 14, the limit plate 13 drives the moving block 6 to slide downward on the sliding frame 5. After sliding, the extrusion wheel 10 rotating on the extrusion block 9 sliding in the extrusion wheel groove 7 on the moving block 6 squeezes the blank cloth. Then, the linear actuator 14 continues to extend, so that the extrusion wheel 10 can cooperate with the surface of the sliding frame 5 to squeeze and fix the blank cloth. As the moving block 6 moves downward, the extrusion wheel 10 gradually presses the extrusion block 9 back into the extrusion wheel groove 7 and squeezes the spring 8. When the moving block 6 drops to a suitable height, the cutting device cooperates with the dividing groove 11 to start trimming and dividing the blank cloth. Under the squeezing of the extrusion wheels 10 on both sides of the dividing groove 11, the blank cloth will not be offset when the cutting device is trimming. The limit plate 13 slides in the two limit grooves 12. When the distance between the two moving blocks 6 is shortened, the length of the limit plate 13 in the two limit grooves 12 increases. When the two moving blocks 6 are away from each other, the length of the limit plate 13 in the two limit grooves 12 decreases, so that the limit plate 13 is always slidably engaged in the limit grooves 12, thereby driving the moving blocks 6 to slide up and down on the sliding frame 5. The setting of the extrusion wheel 10 enables the grey cloth to be normally conveyed while the grey cloth is not easy to move laterally and deviate during trimming.

[0023] In some embodiments, in order to facilitate trimming of the grey cloth, a cutting device is provided including a rotary drive device 15, which can be a motor, a mounting groove 16 is provided in the moving block 6, the mounting groove 16 is located between the two extrusion wheel grooves 7, the rotary drive device 15 is installed in the mounting groove 16, and a cutting blade 17 is installed at the output end of the rotary drive device 15. Through the coordinated arrangement of the cutting blade 17 and the dividing groove 11, the cutting blade 17 can perform trimming work on the grey cloth well.

[0024] In some embodiments, in order to facilitate driving the bidirectional threaded rod 4 to rotate, a second rotation drive device 18 is installed on the frame 1. The second rotation drive device 18 can be a servo motor, and the output end of the second rotation drive device 18 is transmission-connected to the bidirectional threaded rod 4.

[0025] In some embodiments, in order to facilitate the protection of the linear actuator 14 , a plurality of telescopic support rods 19 are installed on the frame 1 , and the plurality of telescopic support rods 19 are evenly distributed on both sides of the linear actuator 14 .

After the grey cloth is trimmed, the waste at the edge will continue to move forward a certain distance under the inertia driven by the unwinding roller 2 and the winding roller 3, so that it can slide down the inclined plane set by the sliding frame 5. After sliding down, under the blocking effect of the side of the sliding frame 5, the waste will gradually accumulate in front of the dividing groove 11, so that it can be blown into the storage box 21 by the fan 20. After working for a period of time, the waste accumulated in the storage box 21 is sucked into the storage groove 22 by the negative pressure generating device 23, so that after the negative pressure generating device 23 has worked for a period of time, the waste can be taken away by the staff.

[0027] In some embodiments, in order to prevent waste from entering the negative pressure generating device 23 and causing damage thereto, a filter screen 24 is installed at the input end of the negative pressure generating device 23 .

[0028] In some embodiments, in order to facilitate the removal of waste materials in the storage tank 22 , a baffle 25 is provided in a sliding connection with the storage tank 22 , and the storage tank 22 is connected to the outside through the baffle 25 .
