Description

Technical Field

[0001] The utility model relates to the field of carbon fiber production, in particular to a constant tension film collecting and taking device. Background Art

[0002] As we all know, the fiber laying and tape laying equipment in the field of carbon fiber molding has the characteristics of high efficiency and stable quality. Compared with the traditional manual production process, it has a higher yield rate and a high degree of automation. With the breakthrough of technology, the localization of equipment is becoming more and more popular. In the use of thermosetting prepreg, the role of the recovery and winding mechanism of PE isolation film is also particularly important. Whether this mechanism can be used normally is directly related to whether the fiber laying and winding can operate normally. The existing isolation film recovery and winding mechanism has unstable tension, which can easily cause the isolation film to break. In addition, the operation of the mechanism is complicated, the maintenance cost is high, and the failure rate is high, which reduces the production efficiency. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a constant tension film collecting and taking device to solve the problem that the tension of the traditional isolation film recovery and winding mechanism is unstable, which easily causes the isolation film to break. It also solves the problems of complex mechanism operation, high maintenance cost, and high failure rate that reduces production efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a constant tension film collecting and taking device, provided with a base, characterized in that the base is connected to a DC torque motor through a bearing, the left side of the rotating shaft is supported by the inner ring of the bearing and connected to the DC torque motor, the fixed disk is fixed on the rotating shaft, the left sides of the four groups of support plates are connected to the fixed disk through a pin shaft, the fixed sleeve and the dial are connected to each other and installed on the right side of the center of the rotating shaft, the right sides of the four groups of support plates are connected to the connecting arm and the dial in turn through a pin shaft, and a spring and a nut are installed in turn on the rotating shaft on the right side of the dial.

[0005] The beneficial effects of the utility model are that a DC torque motor is installed in conjunction with a support plate, a dial and a fixed plate to ensure constant tension when collecting the film, and an installed connecting arm is used to facilitate film removal, simple operation, low debugging and maintenance costs, and low failure rate.

[0011] like Figure 1 and Figure 2 , a base 2 is provided, the base 2 is connected to the DC torque motor 1 through a bearing 2, the left side of the rotating shaft 10 is supported by the inner ring of the bearing 2 and connected to the DC torque motor 1, the fixed plate 4 is fixed to the rotating shaft 10 by a screw 13, the left side of the four groups of support plates 5 are connected to the fixed plate 4 through a pin 11, the fixed sleeve 12 and the dial 7 are connected to each other and installed on the right side of the center of the rotating shaft 10, the right side of the four groups of support plates 5 are connected to the connecting arm 6 and the dial 7 in turn through the pin 11, and the spring 8 and the nut 9 are installed in sequence on the rotating shaft 10 on the right side of the dial 7.

[0012] When the utility model is used, the DC torque motor 1 drives the rotating shaft 10 and all the mechanisms installed on the rotating shaft 10 to rotate to take the film. A quadrilateral connecting rod mechanism is formed between the support plate 5, the connecting arm 6 and the dial 7. This mechanism is in an expanded state under the spring force of the spring 8. The size of the compression force of the spring 8 is adjusted by the rear end nut 9. The positioning sleeve 12 at the front section of the rotating shaft 10 is adjusted to a fixed position by a set screw to ensure the expanded angle of the connecting rod mechanism. When the film collection work is completed, it is only necessary to press the index finger and middle finger on the dial 7 and the thumb on the end face of the rotating shaft 10. The three fingers are subjected to force at the same time to pull the dial 7 to the right. Under the action of the connecting rod, the four sets of support plates 5 produce a slope with a high left and a low right. At this time, the PE film can be easily taken off.
