Description

Technical Field

[0001] The utility model relates to film production equipment, in particular to an automatic film winding device. Background Art

[0002] Existing agricultural film production equipment generally uses a blowing device to first blow out a circular film, then uses a guide device to fold the circular film into a double-layer film, and finally rewinds it using a traction device and a rewinding device. However, existing rewinding devices can only drive a single rewinding roller for rewinding. When the rewinding roller is full, the machine must be stopped to manually remove the full rewinding roller and then manually replace it with a new rewinding roller to continue rewinding. However, each rewinding process takes a considerable amount of time, and the frequent downtime results in a low film rewinding rate, making continuous film rewinding impossible. Furthermore, the low degree of automation requires high labor intensity and low production efficiency. Utility Model Content

[0003] The utility model aims to provide a film automatic winding device which can automatically change rolls, continuously wind up, has a high degree of automation and high production efficiency.

[0004] In order to achieve the above-mentioned purpose, the automatic film winding device provided by the utility model includes a winding roller, a first winding mechanism, a second winding mechanism, a driving mechanism, a film cutting mechanism and a transfer robot. The film passes through the first winding mechanism and the second winding mechanism in sequence along the conveying direction, and the driving mechanism drives the first winding mechanism and the second winding mechanism to move synchronously; the winding roller is arranged at one of the first winding mechanism and the second winding mechanism to wind the film under the drive of the winding mechanism; the film cutting mechanism is arranged below the second winding mechanism to cut the film after winding; the transfer robot is arranged above the first winding mechanism and the second winding mechanism, and can transfer the winding roller to place the winding roller on the first winding mechanism before winding, or transfer the winding roller from the first winding mechanism to the second winding mechanism during the winding process, or unload the winding roller after winding.

[0005] Compared to the prior art, the present invention sequentially arranges a first winding mechanism and a second winding mechanism in the film conveying direction, and arranges a transfer robot above both, and a film cutting mechanism below the second winding mechanism. The transfer robot is used to load and unload the winding roller, and during the winding process, the winding roller is transferred from the first winding mechanism to the second winding mechanism. This allows the first winding mechanism to load another winding roller while the second winding mechanism drives the winding roller to rewind. Furthermore, when the winding roller on the second winding mechanism is fully wound, the film cutting mechanism can automatically cut the film, while the other winding roller of the first winding mechanism continues to rewind. The two do not affect each other, thereby achieving the purpose of automatic loading and unloading, automatic roll changing, and continuous winding, avoiding downtime for roll changing. Furthermore, through the automatic operation of the transfer robot and the film cutting mechanism, the degree of automation is high, eliminating the need for manual operation, and greatly improving production efficiency.

[0006] Preferably, each of the first and second winding mechanisms includes two parallel rotating shafts, each of which supports the winding roller, such that the winding roller is in rolling contact with the two rotating shafts. Providing two rotating shafts for supporting the winding rollers not only drives the winding rollers to rotate, but also facilitates the transfer robot to grasp or place the winding rollers from above, resulting in a simple structure and easy control.

[0007] Preferably, the drive mechanism includes a drive motor, a driving pulley, a belt, and a plurality of driven pulleys, wherein the driven pulleys are disposed one-to-one on the respective rotating shafts of the first and second winding mechanisms; the belt is wound between the driving and driven pulleys; and the output end of the drive motor is connected to the driving shaft. By using a single drive motor to simultaneously drive multiple rotating shafts, the rotation speeds of the rotating shafts are made uniform, thereby ensuring that the winding shafts can rewind stably.

[0008] Preferably, the film cutting mechanism includes a lifting device and a cutter. The output end of the lifting device is connected to the cutter to drive the cutter from bottom to top, passing between the two rotating shafts of the second winding mechanism and cutting the film. By using the lifting device to drive the cutter upward to cut the film, the film can be quickly cut without interfering with the film winding, ensuring continuous film winding and rewinding.

[0009] Preferably, the transfer robot includes a transverse movement mechanism, a longitudinal movement mechanism, a vertical movement mechanism, and a clamping claw. The clamping claw is used to clamp the winding roller and is located at the output end of the vertical movement mechanism. The vertical movement mechanism is located at the output end of the longitudinal movement mechanism, and the longitudinal movement mechanism is located at the output end of the transverse movement mechanism. This allows the clamping claw to flexibly move in the transverse, longitudinal, and vertical directions, thereby quickly and conveniently transferring the winding roller, with easy control and fast and flexible operation.

[0012] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0013] like Figure 1 As shown in the figure, the structure of the automatic film winding device 100 of the first embodiment of the present utility model is shown. The automatic film winding device 100 of this embodiment is used for winding and changing single-layer film, and includes a transfer robot 1, a winding roller 2, a first winding mechanism 3, a second winding mechanism 4, a driving mechanism 5 and a film cutting mechanism 6. The film 200 passes through the first winding mechanism 3 and the second winding mechanism 4 in sequence along the conveying direction, and the driving mechanism 5 drives the first winding mechanism 3 and the second winding mechanism 4 to move synchronously. The winding roller 2 is arranged at one of the first winding mechanism 3 and the second winding mechanism 4 to wind the film 200 under the drive of the winding mechanism; the film cutting mechanism 6 is arranged below between the first winding mechanism 3 and the second winding mechanism 4 to cut the film 200 after winding. The transfer robot 1 is arranged above the first winding mechanism 3 and the second winding mechanism 4, and can transfer the winding roller 2 to place the winding roller 2 on the first winding mechanism 3 before winding, or transfer the winding roller 2 from the first winding mechanism 3 to the second winding mechanism 4 during the winding process, or unload the winding roller 2 after winding.

[0014] For example Figure 1As shown, the first winding mechanism 3 and the second winding mechanism 4 have identical structures. Taking the first winding mechanism 3 as an example, the first winding mechanism 3 includes two side-by-side rotating shafts 31, spaced apart and of equal diameter. The two rotating shafts 31 support the winding roller 2, causing the winding roller 2 to be in rolling contact with the two rotating shafts 31. The film passes between the rotating shafts 31 and the winding roller 2 and is wound by the winding roller 2. The provision of two rotating shafts 31 to support the winding roller 2 not only drives the winding roller 2 to rotate, but also facilitates the transfer robot 1 to grasp or place the winding roller 2 from above, resulting in a simple structure and easy control.

[0015] See also Figure 1 The driving mechanism 5 includes a driving motor 51, a driving wheel 52, a belt 53, and a plurality of driven wheels 54. The driven wheels 54 are respectively arranged on the respective rotating shafts 31 of the first winding mechanism 3 and the second winding mechanism 4 in a one-to-one correspondence; the belt 53 is wound between the driving wheel 52 and the driven wheels 54; and the output end of the driving motor 51 is connected to the driving shaft. By using a driving motor 51 to simultaneously drive multiple rotating shafts 31 to rotate, the rotation speed of each rotating shaft 31 is made the same, thereby ensuring that the winding shaft can be stably wound. The driving wheel 52, the driven wheel 54, and the belt 53 can also be a driving gear, a driven gear, and a chain, respectively, which can also drive the rotating shaft 31 to rotate.

[0016] See also Figure 1 The film cutting mechanism 6 includes a lifting device 61 and a cutter 62. The output end of the lifting device 61 is connected to the cutter 62, driving the cutter 62 to cut the film from bottom to top. In the present invention, the lifting device 61 is a cylinder connected to an air pressure generator to enable the cylinder's telescopic end to extend and retract upward. By using the lifting device 61 to drive the cutter 62 upward to cut the film, the film can be quickly cut without interfering with the film rewinding, ensuring continuous film rewinding and rewinding.

[0017] See also Figure 1The transfer robot 1 is arranged on the frame 8, and the transfer robot 1 includes a transverse moving mechanism 11, a longitudinal moving mechanism 12, a vertical moving mechanism 13 and a clamping claw 14. The clamping claw 14 is used to clamp the winding roller 2 and is arranged at the output end of the vertical moving mechanism 13. The vertical moving mechanism 13 is arranged at the output end of the longitudinal moving mechanism 12, and the longitudinal moving mechanism 12 is arranged at the output end of the transverse moving mechanism 11. In this way, the clamping claw 14 can be flexibly moved in the transverse, longitudinal and vertical directions, so that the winding roller 2 can be quickly and conveniently transferred, and the control is convenient, and the operation is fast and flexible. In this embodiment, the transverse moving mechanism 11, the longitudinal moving mechanism 12 and the vertical moving mechanism 13 can all adopt a motor-driven belt to drive the slider to move on the slide rail, or a motor-driven screw slider. In addition, the vertical moving mechanism 13 can also be driven by a cylinder.

[0018] Combining the above and Figure 1 The working principle of the automatic film winding device 100 of the present invention is described in detail below:

[0019] First, the drive mechanism 5 is activated, driving the rotating shafts 31 on the first and second winding mechanisms 3 and 4. Then, the transfer robot 1 grabs one of the winding rollers 2 and places it on the first winding mechanism 3. At this point, the first winding mechanism 3 drives the winding roller 2 to rotate. The film 200 passes through the first winding mechanism 3 and is wound up by the winding roller 2. When the winding roller 2 is almost fully wound (the radius of the film on the winding roller 2 can be instantly detected using the detector 11, or the length of the film wound up by the winding roller 2 can be calculated by the control system based on the film's conveying speed and time to determine whether a roll change is needed), the transfer robot 1 grabs the winding roller 2 on the first winding mechanism 3 and transfers it to the second winding mechanism 4. Since the film 200 has not been cut, the winding roller 2 continues to be wound on the second winding mechanism 4. At the same time, the transfer robot 1 grabs another winding roller 2 and places it on the first winding mechanism 3. At this time, the winding roller 2 on the first winding mechanism 3 can only rotate along with the rotating shaft 31 on the first winding mechanism 3 and cannot be wound. When the winding roller 2 is fully wound, the film cutting mechanism 6 starts and cuts the film 200. At this time, because the winding roller 2 on the first winding mechanism 3 is rotating, the film 200 will adhere to the winding roller 2 on the first winding mechanism 3 and automatically wind up as the winding roller 2 rotates, while the winding roller 2 with the film on the second winding mechanism 4 only rotates along with the winding roller 2 of the second winding mechanism 4. Afterwards, the transfer robot 1 grabs the winding roller 2 of the second winding mechanism 4 to unload the film. According to the above steps, the film 200 can be continuously and automatically changed and wound up.

[0020] Compared to the prior art, the present invention sequentially arranges a first winding mechanism 3 and a second winding mechanism 4 in the conveying direction of the film 200, and arranges a transfer robot 1 above both, and a film cutting mechanism 6 below the second winding mechanism 4. The transfer robot 1 is used to load and unload the winding roller 2, and during the winding process of the winding roller 2, the winding roller 2 is transferred from the first winding mechanism to the second winding mechanism 4. This allows the first winding mechanism 3 to load another winding roller 2 while the second winding mechanism 4 drives the winding roller 2 to rewind. Furthermore, when the winding roller 2 on the second winding mechanism 4 is fully wound, the film cutting mechanism 6 can automatically cut the film, while the other winding roller of the first winding mechanism 3 continues to rewind. The two mechanisms do not affect each other, thereby achieving the goals of automatic loading and unloading, automatic roll changing, and continuous winding, avoiding downtime for roll changing. Furthermore, the automatic operation of the transfer robot 1 and the film cutting mechanism 6 achieves a high degree of automation, eliminating the need for manual operation and greatly improving production efficiency.

[0021] like Figure 2As shown in the figure, the structure of the second embodiment of the present invention is illustrated. The automatic film winding device of this embodiment can separate a double-layer film before winding two single-layer films 200. There are two automatic film winding devices 100 in this embodiment, each of which is provided with a transition roller 300. A traction roller 400 is also provided before the transition roller 300. The traction roller 400 actively pulls the double-layer film, allowing the double-layer film to pass through the transition roller 300. After passing through the transition roller 300, the double-layer film is separated and transported to its respective automatic film winding device 100. The structure and operating principle of the two automatic film winding devices 100 are the same as those of the first embodiment described above and will not be repeated here.

[0022] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
