[0003] Because the membrane sheet material is cut into pieces, each layer is glued, and then stacked together, after being stacked to the required number of layers, the membrane sheet material is rolled together, if the outermost layer of the membrane sheet material is not tensioned, the rolled membrane element will be loose, which will result in poor air tightness and excessive outer diameter, and the product quality is unqualified. In order to solve this problem, the bottom guide cloth needs to be counterweighted to ensure that the bottom guide cloth has a certain tension.

[0004] Method 1: a recess is made in the lifting platform support plate, a counterweight block or a counterweight rod is added at the position, and the guide cloth is pressed to counterweight. Disadvantages: the counterweight block will jump during the rolling process, and the counterweight force cannot be changed. The tension cannot be adjusted.

[0005] Method 2: a torsion motor is added behind the lifting platform, a counterweight clamp plate is added to the platform surface, and the bottom guide cloth is clamped by the clamp plate. Disadvantages: the upper membrane sheet will be pushed backward during the membrane sheet rolling process, and will be raised after hitting the clamp plate, which will cause the membrane sheet to wrinkle, and the tension is a fixed value during the rolling process, and will not change with the process. The effect is poor.

Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 And Figure 4The application discloses an industrial film tension counterweight device, which comprises a counterweight platform 2 arranged on one side of a film winding platform 1, a support frame 3 fixedly connected to the top of the counterweight platform 2, a platform plate 4 fixedly connected to the top of the support frame 3, a plurality of slot-shaped holes 5 formed in the upper surface of the platform plate 4, a sliding plate 6 slidably connected to the top of the counterweight platform 2, a plurality of clamping air cylinders 7 fixedly connected to the sliding plate 6, the clamping air cylinders 7 being arranged in a number corresponding to the number of the slot-shaped holes 5, a counterweight clamping jaw 8 connected to the output end of the clamping air cylinder 7, the counterweight clamping jaw 8 being capable of clamping the guide cloth, and the number of the clamping air cylinders 7 and the counterweight clamping jaw 8 being designed according to the width of the guide cloth in actual use. The wider the guide cloth, the more the clamping air cylinders 7 and the counterweight clamping jaw 8 are arranged, so that the stability of clamping the guide cloth can be ensured, a torsion motor 9 is fixedly installed on one side of the top of the counterweight platform 2 and below the support frame 3, a winding roller 10 is fixedly connected to the output end of the torsion motor 9, the winding roller 10 is driven to rotate by the torsion motor 9, so that the pull rope 11 can be wound on the winding roller 10, the tension of the pull rope 11 can be changed, the pulling force of the sliding plate 6 can be changed, the control of the tension of the guide cloth can be realized, the pull rope 11 is wound on the outer surface of the winding roller 10, and one end of the pull rope 11 is fixedly connected to one side of the front surface of the sliding plate 6.

[0027] The specific debugging principle is as follows: for example, the initial value is an initial tension of 10 kg, the final tension is 12 kg, the winding number from the beginning to the end is 2, if the control sends 10,000 pulses for winding one circle of the film, then 20,000 pulses are needed for rotating 2 circles; the tension output range of the torsion motor is 0 kg-20 kg corresponding to 0 V-10 V, so that the voltage received is 5 V when the tension is 10 kg, the voltage is 6 V when the tension is 12 kg, and the value in the controller is converted to 0-10,000 corresponding to 0 V-10 V. Then the controller calculates the tension change relationship as follows: the initial tension value + the pulse sending amount of the film motor from the beginning to the end ÷ (the final tension value - the initial tension value); that is to say, (5000 + the real-time pulse amount of the film) / (6000-5000), the initial tension output value (5000 + 0 / (6000-5000) - the final tension output value (5000 + 20000 / (6000-5000), after the controller processing, it is an output relationship such that the tension size and the winding diameter size are linearly increased or decreased, and the ideal and set change tension value is achieved.
