For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0019] Referring to Figures 1 to 4 The efficient unwinding device, comprising: a rack 1, a plurality of unwinding drum mechanisms 2 arranged on the rack 1, and a winding drum mechanism 3 arranged on the rack 1, wherein the winding drum mechanism 3 is used for collecting the film on the plurality of unwinding drum mechanisms 2.
[0020] In the above embodiment, the plurality of unwinding drum mechanisms 2 are arranged side by side on the rack 1, which can simultaneously process a plurality of waste film sources. The winding drum mechanism 3 is located on one side of the rack 1 and is designed to collect waste film from each unwinding drum mechanism 2, thereby realizing unified management and processing of waste film, reducing the trouble of manual carrying and classification, and improving the convenience and efficiency of waste processing. It is worth noting that, referring to Figure 1 In the present embodiment, the unwinding drum mechanism 2 is provided with four, and the winding drum mechanism 3 is one. The winding drum mechanism 3 collects the film on the four unwinding drum mechanisms 2 at the same time and concentrates the film on the winding drum mechanism 3.
[0021] Referring to Figures 1 to 4 In another embodiment, the unwinding drum mechanism 2 comprises an unwinding drum 21, an unwinding inflation shaft 22, a tension feedback module 23, and a tension control module 24. The unwinding inflation shaft 22 is arranged on the rack 1, the unwinding drum 21 is arranged on the unwinding inflation shaft 22, the tension feedback module 23 is used to detect the tension during unwinding and feed back the feedback value to the tension control module 24, and the tension control module 24 brakes the unwinding inflation shaft 22 according to the feedback value.
[0022] In the above embodiment, the unwinding inflation shaft 22 is arranged on the rack 1 as a support and driving device of the unwinding drum 21. The two ends of the unwinding drum 21 are respectively mounted on the unwinding inflation shaft 22, and the tight fixation is realized through the inflation force of the inflation shaft, thereby ensuring the stability during unwinding.
[0023] During unwinding, the tension feedback module 23 detects the tension change generated by the unwinding drum 21 during rotation in real time through a sensor. This change is converted into an electrical signal, and the specific tension value is obtained after processing. Subsequently, these tension values are fed back to the tension control module 24 in real time.
[0024] After receiving the value from the tension feedback module 23, the tension control module 24 immediately performs operation analysis to determine whether the current tension meets the preset range. If the tension is too large or too small, the tension control module 24 will issue a braking instruction to adjust the rotation speed or torque of the unwinding inflation shaft 22, thereby realizing accurate control of the unwinding tension. This process ensures that the film can maintain a stable tension state during unwinding, thereby avoiding problems such as film damage or uneven unwinding caused by tension fluctuations.
[0025] Referring toFigures 1 to 4 In another embodiment, the take-up drum mechanism 3 includes a take-up drum 31, a take-up air shaft 32, and a motor 33. The take-up air shaft 32 is disposed on the frame 1, the take-up drum 31 is disposed on the take-up air shaft 32, and the motor 33 is used to drive the take-up air shaft 32 to rotate.
[0026] In the above embodiments, the combined design of the take-up drum 31 and the take-up air shaft 32 ensures stability and reliability during the take-up process. The take-up air shaft 32 is mounted on the frame 1 and expands and contracts through its internal air pressure device, thereby tightly securing take-up drums 31 of different diameters. Collecting the film into a single take-up drum 31 improves the efficiency of film waste collection, eliminating the previous need for manual pulling or cutting, protecting the drums, and improving the convenience and efficiency of waste handling and drum turnover.
[0027] Secondly, the motor 33 serves as the drive source, providing power for the rotation of the take-up air shaft 32. The motor 33 is connected to the take-up air shaft 32 via gear transmission. When the motor 33 starts, it smoothly drives the take-up air shaft 32 to rotate, thereby achieving continuous film winding. The power and speed of the motor 33 can be adjusted according to actual needs to meet the winding requirements of different films.
[0028] As a preferred option, the motor 33 can also be connected to the take-up air shaft 32 via a speed reducer to adjust the speed and increase the torque. The speed reducer can convert the high-speed rotation of the motor 33 into a low-speed, high-torque output, thereby ensuring stability and reliability during the take-up process.
[0029] In addition, a frequency converter can be used to control the speed of motor 33 to achieve more precise winding control.
[0030] Please see Figures 1 to 4 In another embodiment, an encoder 4 is also included, which is used to detect the rotational speed of the unwinding drum 21 and the winding drum 31 and feed the detected value back to the motor 33.
[0031] In the above embodiment, the encoder 4 detects the rotational speed of the unwinding drum 21 and the take-up drum 31, and feeds back the detected value to the motor 33 to adjust the speed of the motor 33, ensuring stable tension and achieving efficient and stable collection of the film.
[0032] Please see Figures 1 to 4 In another embodiment, the tension control module 24 is an unwinding shaft magnetic powder brake.
[0033] In the above embodiment, the tension of the winding is controlled by the braking torque of the unwinding shaft magnetic powder brake during unwinding. As the winding diameter of the winding continuously decreases, the braking torque must be continuously reduced to maintain a constant tension. The tension of the winding is detected by the tension feedback module 23, and when the value is reached, the magnetic powder is magnetized and forms a magnetic powder chain, thereby generating a certain binding force between the stator and the rotor of the unwinding inflatable shaft 22, and then applying a corresponding braking torque to the rotor.
[0034] At the same time, the unwinding inflatable shaft 22 plays a role in fixing and supporting the winding during unwinding. Through inflation and deflation operations, the unwinding inflatable shaft 22 can conveniently realize the feeding and fixing of the winding.
[0035] In summary, the structure principle of the unwinding shaft magnetic powder brake braking the unwinding inflatable shaft 22 involves the electromagnetic effect of the unwinding shaft magnetic powder brake and the inflation and deflation control of the inflatable shaft, which cooperate with each other to realize the smooth progress of the unwinding process.
[0036] Please refer to Figures 1 to 4 In another embodiment, a tension sensor is further included, which is used to detect the tension of the film between the unwinding drum 21 and the winding drum 31 and feed the detection value to the motor 33.
[0037] In the above embodiment, the tension sensor detects the tension of the film between the unwinding drum 21 and the winding drum 31 in real time and feeds the detection value to the motor 33, and the motor 33 adjusts the rotating speed accordingly to ensure the stability of the tension and realize the smooth and efficient collection and processing of the film.
[0038] Please refer to Figures 1 to 4 In another embodiment, the tension control module 24 is a winding shaft power driver.
[0039] In the above embodiment, the motor 33 is started to drive the winding drum 31 to rotate, and at the same time, the tension sensor detects the tension of the film between the unwinding drum 21 and the winding drum 31 in real time and feeds the detection value to the winding shaft power driver. The driver adjusts the power of the winding shaft according to the feedback value, thereby controlling the tension and ensuring the smooth and efficient collection of the film.
[0040] In summary, the working principle is as follows:
[0041] The operator needs to manually wind one end of the film on each unwinding drum 21 to the winding drum 31.
[0042] Then, the motor 33 is started. The motor 33 drives the winding inflatable shaft 32 to rotate, thereby driving the winding drum 31 to rotate. Since the two ends of the winding drum 31 are stably arranged on the winding inflatable shaft 32, the winding drum 31 can rotate smoothly and continuously.
[0043] While the winding drum 31 is rotating, the film from each unwinding drum mechanism 2 is gradually pulled tight and wound onto the winding drum 31. In order to ensure that the tension of the film is stable during unwinding and winding, each unwinding drum mechanism 2 is equipped with a tension feedback module 23, an encoder 4 and a tension control module 24 (unwinding shaft magnetic powder brake). The tension feedback module 23 detects the tension of the film. Once a tension fluctuation is detected, this information is immediately fed back to the unwinding shaft magnetic powder brake. The unwinding shaft magnetic powder brake then dynamically adjusts its braking force according to the fed-back tension value, thereby achieving precise control of the unwinding tension; the encoder 4 detects the unwinding and winding speed, and once the speed is too fast or too slow, signals are fed back to the motor 33 to dynamically adjust the rotation speed.
[0044] As the winding drum 31 continues to rotate, the film is tightly and orderly wound onto the winding drum 31 until all the film on the unwinding drums 21 is completely collected.
[0045] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belong to the scope of the present application.
