Description

Technical Field

[0001] The utility model belongs to the technical field of cutting for tape processing, and particularly relates to a cutting machine for processing flame-retardant acetate cloth tape. Background Art

[0002] The acetate cloth tape is mainly prepared by evenly coating the configured acrylic acid on the surface of the treated acetate cloth, putting it into a drying room to remove volatile solvents and reacting at a high temperature of 150 degrees, so as to generate a sticky polymer material, which is the tape we usually use. In the production of the tape, after the finished tape is wound by a winding device, it is cut by a tape cutting machine.

[0003] When cutting the existing tape, the tape is first put in, then the tape is pressed by a pressing component, and finally cut. However, when cutting, the blade contacts the tape, and a part of the tape will adhere to the surface of the blade. After long-term use, the adhesive liquid on the tape adheres to the surface of the blade, resulting in an uneven cross-section of the tape after cutting and affecting the quality of the cut tape.

[0004] Therefore, we propose a cutting machine for processing flame-retardant acetate cloth tape to solve the above problems. Content of the Utility Model

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0021] Referring to Figures 1 - 3 , a cutting machine for processing flame-retardant acetate cloth tape includes a workbench 1. A U-shaped frame 2 is fixedly connected to the center of the top surface of the workbench 1. A cylinder 6 is fixedly installed on the top surface of the U-shaped frame 2. A connecting plate 10 is provided at the moving end of the cylinder 6. The connecting plate 10 is located inside the U-shaped frame 2. A pressing plate 11 is provided below the connecting plate 10. The pressing plate 11 is in contact with the adhesive tape roller. A connecting component is provided between the connecting plate 10 and the pressing plate 11. A blade 15 penetrating through the pressing plate 11 is fixedly connected to the bottom of the connecting plate 10. The blade 15 passes through the pressing plate 11. Rotating seats 18 are rotatably installed on both sides of the top surface of the pressing plate 11. Scraping blades 17 for scraping the adhesive liquid on both sides of the blade 15 are installed on both rotating seats 18. The top ends of the scraping blades 17 are abutted against both ends of the blade 15. When there is adhesive liquid on the scraping blades 17, first, the rotating seats 18 are flipped to turn the scraping blades 17 to the other side for cleaning. An installation groove 21 is opened on one side of the top surface of the workbench 1. A guiding component is provided in the installation groove 21. And a feeding component for pushing the adhesive tape under the U-shaped frame 2 is provided on the top surface of the workbench 1. A discharge groove 9 is opened on the other side of the workbench 1. A baffle 13 in sliding connection with one end of the adhesive tape is installed in the discharge groove 9. The length of the adhesive tape to be cut is determined by the position of the baffle 13. The connecting plate 10 is pushed downward by the cylinder 6. Then, when the connecting plate 10 descends, the blade 15 descends synchronously. The pressing plate 11 presses the adhesive tape, and then cutting is performed. When the blade 15 rises, the blade 15 contacts the scraping blades 17 on the top surface of the pressing plate 11, so as to scrape the adhesive liquid on the blade 15, make the cross-section of the cut adhesive tape flat, and improve the quality after cutting.

[0022] Referring to Figure 3 , the connecting component includes two telescopic rods 16 and two springs 12. The two telescopic rods 16 are respectively fixedly connected between the two ends of the connecting plate 10 and the pressing plate 11. The two telescopic rods 16 are located on both sides of the blade 15. The two springs 12 are fixedly connected between the connecting plate 10 and the pressing plate 11 and are respectively sleeved outside the two telescopic rods 16. By pushing the connecting plate 10 to descend by the cylinder 6, the pressing plate 11 below the connecting plate 10 fixes the adhesive tape roller. Due to the continuous movement of the connecting plate 10, the telescopic rods 16 are contracted and the springs 12 are compressed, so as to fix the adhesive tape roller. At the same time, the blade 15 passes through the pressing plate 11 to cut the fixed adhesive tape roller.

[0023] Referring to Figure 4, the guiding assembly includes two guiding side plates 3. The installation groove 21 is connected with a moving groove 14. A bidirectional threaded rod 20 is rotatably installed in the moving groove 14. The two guiding side plates 3 are respectively installed at both ends of the bidirectional threaded rod 20. One end of the bidirectional threaded rod 20 extends out of the side surface of the workbench 1, and the extended end of the bidirectional threaded rod 20 is fixedly connected with a handwheel 7. By rotating the handwheel 7, the bidirectional threaded rod 20 rotates synchronously at the same time, driving the guiding side plates 3 on both sides to lift the adhesive tape roller from the top surface of the workbench 1, so that the adhesive tape roller slides between the two guiding side plates 3.

[0024] Refer to Figure 2 , the material pushing assembly includes a push plate 4. A lead screw 19 is rotatably installed in the installation groove 21. The push plate 4 is installed on the lead screw 19. A motor 5 connected to the lead screw 19 is fixedly installed on one side of the workbench 1. By driving the lead screw 19 with the motor 5, the rotation of the lead screw 19 pushes the push plate 4 towards the U-shaped frame 2. At the same time, due to the movement of the push plate 4, the adhesive tape roller placed between the two guiding side plates 3 is pushed.

[0025] Refer to Figure 4 , the moving groove 14 is located below the installation groove 21, so that the moving groove 14 and the installation groove 21 are staggered and do not interfere with each other, and the moving groove 14 is perpendicular to the installation groove 21, and the intersecting part is communicated.

[0026] Refer to Figure 2 , a receiving box 8 is provided below the discharge chute 9 to facilitate the collection of the cut adhesive tape.

[0027] Working principle:

[0028] First, place the adhesive tape roller on the top surface of the workbench 1, and then rotate the handwheel 7. Driven by the rotation of the handwheel 7, the bidirectional threaded rod 20 rotates synchronously at the same time, driving the guiding side plates 3 on both sides to lift the adhesive tape roller from the top surface of the workbench 1. The motor 5 drives the lead screw 19, and the rotation of the lead screw 19 pushes the push plate 4 towards the U-shaped frame 2. At the same time, due to the movement of the push plate 4, the adhesive tape roller placed between the two guiding side plates 3 is pushed. The air cylinder 6 pushes the connecting plate 10 to descend, and the pressing plate 11 below the connecting plate 10 fixes the adhesive tape roller. Due to the continuous movement of the connecting plate 10, the telescopic rod 16 is contracted and the spring 12 is compressed to fix the adhesive tape roller. At the same time, the blade 15 passes through the pressing plate 11 to cut the fixed adhesive tape roller. When the blade 15 rises, the blade 15 contacts the scraping blade 17 on the top surface of the pressing plate 11, realizing the scraping of the glue on the blade 15, making the cross-section of the cut adhesive tape flat and improving the quality after cutting.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
