Technical Field

[0001] The utility model relates to the technical field of cloth opening machines, in particular to a control system of a full-automatic cloth opening machine. Background Art

[0002] In the artificial leather production process, a fabric opening machine is typically used. This machine is a processing device used to flatten and cut fabric (base fabric), loosening and cutting wrinkled and tangled fabric materials. The fabric opening machine is typically equipped with multiple horizontal rollers, over which the fabric is conveyed and flattened. The flattened fabric moves to the end of the machine, where it is cut by a cutting mechanism.

[0003] The cloth opening machine needs to maintain appropriate cloth tension during operation. Excessive tension may cause the cloth to stretch and deform, while too little tension may cause the cloth to loosen, affecting the cloth opening effect. Although the existing cloth opening machine has a cloth tension adjustment module, it is easily affected by factors such as cloth material, thickness, and speed during the cloth conveying process, resulting in tension fluctuations. The existing adjustment module cannot adjust the tightness of the cloth in real time according to the cloth conveying situation, affecting the cloth opening quality.

[0004] Therefore, it is necessary to invent a control system of a fully automatic cloth-opening machine to solve the above problems. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The utility model provides Figure 1 、 Figure 2 and Figure 6 The control system of a fully automatic cloth opening machine shown in the figure includes an equipment frame 1 and a control module 6. Positioning rollers 11 are rotatably connected on the left and right sides of the equipment frame 1. A tension roller 21 is provided in the middle of the equipment frame 1. An adjustment mechanism is provided on the lower side of the tension roller 21. The adjustment mechanism includes a positioning block 2, a support frame 22, an electric cylinder 3, a support plate 31, and a pressure sensor 32. A speed sensor 46 and a detection camera 45 are respectively provided on the left and right sides of the upper end of the equipment frame 1. The electric cylinder 3, the pressure sensor 32, the speed sensor 46 and the detection camera 45 are all connected to the control module 6 through signal lines. A cloth body 5 is provided between the positioning roller 11 and the tension roller 21.

[0033] Among them, the fabric body 5 passes through the lower side of the positioning rollers 11 on the left and right sides, and the electric cylinder 3 pushes the tension roller 21 upward, pushes the middle part of the fabric body 5 upward, and adjusts the tension of the fabric body 5. In the process of opening the cloth, the traction module drives the fabric body 5 to move, and the fabric body 5 is opened. At the same time, the speed sensor 46 and the detection camera 45 are used to detect the speed of the cloth movement and whether there are wrinkles on the surface.

[0034] In addition, when the tension roller 21 supports the fabric body 5 upward, the fabric body 5 will apply a certain pressure to the tension roller 21. At this time, the pressure sensor 32 detects the pressure generated by the fabric body 5. First, the pressure generated under the standard tension of the fabric body 5 of different materials is set as a threshold in the control module 6. When the pressure generated during the movement of the fabric is higher than the threshold, the control module 6 controls the electric cylinder 3 to move the tension roller 21 downward to relax the fabric body 5. When the pressure generated during the movement of the fabric is lower than the threshold, the control module 6 controls the electric cylinder 3 to move the tension roller 21 upward to tighten the fabric body 5, so that the fabric body 5 maintains a suitable tension.

[0035] See Figures 2 to 4 , positioning grooves 12 are provided on the front and rear surfaces of the equipment frame 1, and positioning blocks 2 are slidably connected inside the two groups of positioning grooves 12. The front and rear ends of the tension roller 21 are rotatably connected to the front and rear two groups of positioning blocks 2 respectively, and the front and rear ends of the support frame 22 are fixedly connected to the front and rear two groups of positioning blocks 2 respectively. The left and right sides of the support frame 22 are fixedly connected with two groups of first connecting blocks 23, and the lower end of the first connecting block 23 is fixedly connected with a positioning rod 24. The electric cylinder 3 is installed on the lower side of the tension roller 21, and the upper end of the telescopic rod in the electric cylinder 3 is fixedly connected to the support plate 31. Two groups of second connecting blocks 33 are fixedly connected on the left and right sides of the support plate 31, and a positioning hole 34 is provided on the surface of the second connecting block 33, and the positioning rod 24 is slidably connected to the positioning hole 34.

[0036] Specifically, during the process of tightening the tension roller 21, the telescopic rod in the electric cylinder 3 pushes the support plate 31 upward. At this time, the support plate 31 pushes the support frame 22 upward. The support frame 22 drives the positioning blocks 2 on the front and rear sides to slide upward inside the positioning groove 12, thereby driving the tension roller 21 to move upward to tighten the fabric body 5.

[0037] See Figure 2 and Figure 5 The left and right sides of the upper end of the equipment rack 1 are fixedly connected to the first adjusting block 41, the side of the first adjusting block 41 is rotatably connected to the first adjusting rod 4, the end of the first adjusting rod 4 away from the first adjusting block 41 is rotatably connected to the second adjusting rod 42, the end of the second adjusting rod 42 away from the first adjusting rod 4 is rotatably connected to the second adjusting block 43, and the end of the second adjusting block 43 away from the second adjusting rod 42 is fixedly connected to the mounting block 44, the detection camera 45 is fixedly mounted on the lower surface of the right mounting block 44, and the speed sensor 46 is fixedly mounted on the lower surface of the left mounting block 44.

[0038] It should be added that the first adjusting rod 4 rotates around the first adjusting block 41, the second adjusting rod 42 rotates around the first adjusting rod 4, and the second adjusting block 43 rotates around the second adjusting rod 42, thereby adjusting the position and angle of the mounting block 44. During use, according to actual needs, the angle and position of the mounting block 44 are adjusted, and the position and angle of the detection camera 45 and the speed sensor 46 are adjusted. When the detection speed is too fast, the control module 6 reduces the cloth movement speed. At the same time, when wrinkles are detected on the surface of the cloth body 5, the control module 6 issues a warning to remind the staff to adjust the cloth in time.

[0039] The working principle of the present invention is as follows: the cloth body 5 is supported by the tension roller 21. At this time, the cloth body 5 will generate a certain pressure on the tension roller 21. The pressure sensor 32 detects the pressure generated by the cloth body 5, and then determines whether the tension of the cloth body 5 is normal through the control module 6, and adjusts the height of the tension roller 21 in real time through the electric cylinder 3, thereby effectively maintaining the tension of the cloth body 5 and improving the quality of cloth opening.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
