DETAILED DESCRIPTION

[0022] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings. Embodiment 1:

[0023] This embodiment provides a technical solution: a film winding device for a film blowing machine, such as Figure 1-Figure 9 As shown, it includes a frame 1, multiple guide rollers 2, a winding assembly 3, a control terminal 6 and a placing roller frame 7, the multiple guide rollers 2 are used to limit the position of the moving film, the multiple guide rollers 2 are installed between the frames 1, the winding assembly 3 is used to wind the film, the winding assembly 3 is arranged at the rear side of the frame 1, the control terminal 6 is arranged at one side of the frame 1, a controller is arranged on the control terminal 6, the hydraulic cylinder 501 and the brake motor 3012 are both communicatively connected to the controller, the controller is also communicatively connected to the speed regulating unit of the brake motor 3012, the placing roller frame 7 is used to place the film in the initial state, the placing roller frame 7 is arranged at the bottom front side of the frame 1, the placing roller frame 7 includes two placing plates 701 and a roller shaft rod 702, the two placing plates 701 are respectively installed on both sides of the bottom front side of the frame 1, and the two ends of the roller shaft rod 702 are respectively clamped on the placing plates 701.

[0024] In the specific implementation, such as Figure 1-Figure 3 As shown, the winding assembly 3 is arranged at the rear side of the frame 1, and the winding assembly 3 includes a driving structure 301, two roller handles 302 and a winding roller 303. The two roller handles 302 are respectively installed at both ends of the winding roller 303. The driving structure 301 includes a mounting plate 3011, a brake motor 3012 and a reducer 3013. The brake motor 3012 is an adjustable speed motor. The mounting plate 3011 is installed on one side of the frame 1, the reducer 3013 is installed on the mounting plate 3011, and the brake motor 3012 is installed on the reducer 3 013, the reducer 3013 is braked by the brake motor 3012, one of the roller handles 302 is installed at the output end of the reducer 3013, and the brake motor 3012 can control the rotation of the roller handle 302 and the winding roller 303. The reducer 3013 is used to control the rotation speed not to be too fast. The winding roller 303 has an inner cavity, and a plurality of reducing components 4 for controlling the diameter of the winding roller 303 are arranged in the inner cavity. Adjustment components 5 for controlling the adjustment of the reducing components 4 are arranged in the two roller handles 302.

[0025] In the specific implementation, such as Figure 4 and Figure 5As shown, the reducing assembly 4 includes a reducing block 401, two mounting springs 402 and two connecting pieces 403. A plurality of slots are evenly arranged between the inner cavity and the outer wall of the winding roller 303. The reducing block 401 is mounted in the slots. The two connecting pieces 403 are respectively mounted at both ends of the reducing block 401. The mounting springs 402 are mounted between the connecting pieces 403 and the inner wall of the inner cavity. A through opening is formed at the center of the plurality of connecting pieces 403. The connecting piece 403 is connected to the inner wall of the inner cavity through the mounting springs 402. By controlling the position of the connecting piece 403, the mounting springs 402 can be squeezed and the position of the reducing block 401 can be adjusted to achieve the effect of adjusting the available diameter of the winding roller 303.

[0026] Furthermore, the connecting member 403 includes an arc piece 4031 and an extension piece 4032. The arc piece 4031 is installed on the inner side of the end of the reducing block 401, and the extension piece 4032 is installed on the outer wall of the arc piece 4031 at one end close to the center of the winding roller 303. The adjustment component 5 can adjust the position of the arc piece 4031 and the reducing block 401 by controlling the position of the extension piece 4032.

[0027] In the specific implementation, such as Figure 4 As shown, the adjustment component 5 includes a hydraulic cylinder 501 and a control cone block 502 with a gradually increasing diameter. A mounting groove is provided on one side of the roller handle 302. The hydraulic cylinder 501 is installed on the inner wall of the mounting groove. The control cone block 502 is installed at the output end of the hydraulic cylinder 501. The end of the control cone block 502 corresponds to the through port. When performing variable diameter adjustment, the hydraulic cylinder 501 in the adjustment component 5 can be started to push the control cone block 502 to move into the winding roller 303. The control push block can gradually contact each connecting member 403 and push the connecting member 403 outward. The connecting member 403 can adaptively squeeze the installation spring 402. At the same time, each variable diameter block 401 can be moved out of the card slot. The available diameter of the winding roller 303 increases continuously. After adjusting to the appropriate diameter, closing the hydraulic cylinder 501 can complete the variable diameter adjustment.

[0028] In the specific implementation, such as Figure 4 and Figure 5As shown, at least one light-emitting diode 8 is installed on one side of one of the variable diameter blocks 401, and a photosensitive sensor 9 is installed on one side of the inner wall of the card slot. The photosensitive sensor 9 corresponds to the light-emitting diode 8, and the photosensitive sensor 9 is communicatively connected with the controller. Before use, the controller needs to be used to set the initial rotation speed of the brake motor 3012 under different diameters. The photosensitive sensor 9 cooperates with the light-emitting diode 8 to automatically control the rotation speed of the brake motor 3012 according to the change in the available diameter of the winding roller 303. When the variable diameter block 401 is located in the card slot, the available diameter of the winding roller 303 is small, so the initial rotation speed of the motor is relatively fast during winding, which can ensure that the film is subjected to sufficient initial tension. After the variable diameter block 401 is used for diameter reduction, the light-emitting diode 8 moves to a position aligned with the photosensitive sensor 9, and the photosensitive sensor 9 can sense the light information and transmit it to the controller. The controller can control the speed regulating unit of the brake motor 3012 to change the initial rotation speed of the brake motor 3012. Therefore, the motor speed can be automatically controlled during the diameter reduction adjustment, thereby ensuring that the tension of the film is appropriate when it moves, and preventing the film from being damaged by stretching or having seams in the stack.

[0029] When implementing this embodiment, it is necessary to set the initial speed of the brake motor 3012 under different diameters through the controller before use. The photosensitive sensor 9 cooperates with the light-emitting diode 8 to automatically control the rotation of the brake motor 3012 according to the change of the available diameter of the winding roller 303. When the available diameter of the winding roller 303 is changed without using the diameter-changing component 4, the brake motor 3012 can be directly controlled according to the following example. Fig. 9 After the film is arranged in the state shown, it can be rolled up. When the diameter-changing block 401 is located in the card slot, the available diameter of the winding roller 303 is small. Therefore, the initial speed of the motor is relatively fast during rolling, which can ensure that the film is subjected to sufficient initial tension. After the diameter-changing block 401 is used to change the diameter, the light-emitting diode 8 moves to a position aligned with the photosensor 9. The photosensor 9 can sense the light information and transmit it to the controller. The controller can control the speed regulating unit of the brake motor 3012 to change the initial speed of the brake motor 3012. Therefore, the motor speed can be automatically controlled when the diameter-changing adjustment is performed. After the adjustment is completed, follow the steps as shown in the figure. Fig. 9 The film can be rolled up after being arranged in the state shown, so that the tension of the film can be ensured to be appropriate when it moves, thereby preventing the film from being stretched and damaged or having gaps in the stack. When rolling up, the brake motor 3012 is started, and the brake motor 3012 can drive the reducer 3013 and the winding component 3 to rotate to complete the film rolling. Embodiment 2:

[0030] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 1 , Figure 6 and Figure 7 As shown, in order to better implement the present invention, the following configuration is particularly adopted: In a specific implementation, at least one guide roller 2 is an auxiliary roller 10, and the auxiliary roller 10 includes two arc plates 1001 and two mounting plates 1002. The two arc plates 1001 are mirror-imaged up and down and are mounted in a close fit at one end. The two mounting plates 1002 are mounted at both ends of the two arc plates 1001. There is an internal space inside the arc plates 1001, so it is convenient to arrange the internal structure. A guide groove 12 is formed between the other ends of the two arc plates 1001, and wrinkle removal components 11 that can assist in wrinkle removal of the film are arranged on both sides of the auxiliary roller 10.

[0031] Furthermore, the wrinkle removal component 11 is arranged at a position where it can contact the film. The wrinkle removal component 11 includes a travel electric telescopic rod 1101, a mounting folding piece 1102, an adjustment electric telescopic rod 1103 and a sphere 1104. The travel electric telescopic rod 1101 is installed on the mounting piece 1002, the mounting folding piece 1102 is installed at the output end of the travel electric telescopic rod 1101, and the adjustment electric telescopic rod 1103 is installed on the front side of the mounting folding piece 1102. The movement of the mounting folding piece 1102 can be controlled by the travel electric telescopic rod 1101. The sphere 1104 is located in the guide groove 12 and is installed at the output end of the adjustment electric telescopic rod 1103. The use position of the sphere 1104 can be controlled by adjusting the electric telescopic rod 1103. When the travel electric telescopic rod 1101 is in a fully extended state, the sphere 1104 is located near the center of the auxiliary roller 10. At this time, the adjustment electric telescopic rod 1103 is in a fully retracted state.

[0032] Furthermore, the braking direction of the electric telescopic rod 1103 is adjusted from the inside of the arc plate 1001 toward the outside of the arc plate 1001. When the electric telescopic rod 1103 is in the retracted state, the sphere 1104 is located on the inside of the arc plate 1001, and when the electric telescopic rod is in the extended state, the sphere 1104 is located on the outside of the arc plate 1001. During the retraction of the electric telescopic rod 1101, the electric telescopic rod 1103 is adjusted to be changed from the retracted state to the extended state. Therefore, the sphere 1104 can move from the center position of the guide groove 12 from the inside of the arc plate 1001 to the outside of the arc plate 1001. After the two spheres 1104 move out of the arc plate 1001, they can move from the center position to both sides, and at the same time, they can scrape the film from the center position to both sides, so that the film can be fully unfolded without wrinkles.

[0033] When this embodiment is implemented, the brake motor 3012 is started, and the brake motor 3012 can drive the reducer 3013 and the winding component 3 to rotate to complete the film winding. When winding, the travel electric telescopic rod 1101 and the adjustment electric telescopic rod 1103 are started, the travel electric telescopic rod 1101 begins to retract, and at the same time the adjustment electric telescopic rod 1103 is changed from a retracted state to an extended state. Therefore, the sphere 1104 can start from the center position of the guide groove 12 and move from the inside of the arc plate 1001 to the outside of the arc plate 1001. After the two spheres 1104 move out of the arc plate 1001, they can move from the center position to both sides, and at the same time can scrape the film from the center position to both sides, so that the film can be fully unfolded without wrinkles. Embodiment 3:

[0034] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 2 , Figure 3 and Figure 8 As shown, in order to better implement the present invention, the following configuration is particularly adopted: In a specific implementation, a positioning component 13 for assisting in positioning the winding component 3 is provided on the other side of the frame 1. The positioning component 13 includes a positioning frame 1301, an upper clamping block 1302 and a lower clamping block 1303. A convex plate 14 is extended from the center position of the positioning frame 1301. The upper clamping block 1302 and the lower clamping block 1303 are mirror-imaged and are both rotatably connected to the convex plate 14. A positioning groove 15 for placing the roller handle 302 is provided at the connection between the upper clamping block 1302 and the lower clamping block 1303. A control component 16 for controlling the opening and closing of the upper clamping block 1302 and the lower clamping block 1303 is provided in the positioning frame 1301. By controlling the opening and closing of the upper clamping block 1302 and the lower clamping block 1303 through the control component 16, it is convenient to position the winding roller 303 and remove the wound film.

[0035] Furthermore, the control component 16 includes a control cylinder 1601, a linkage plate 1602, an upper pull plate 1603 and a lower pull plate 1604. The control cylinder 1601 is installed in the positioning frame 1301, and the linkage plate 1602 is installed at the output end of the control cylinder 1601. The positioning frame 1301 is provided with two placement openings 17. The upper pull plate 1603 is arranged in the placement opening 17 and its two ends are rotatably connected to the upper end of the linkage plate 1602 and the upper clamping block 1302 respectively. The lower pull plate 1604 is arranged in the placement opening 17 and its two ends are rotatably connected to the lower end of the linkage plate 1602 and the lower clamping block 1303 respectively. The control component 16 can simultaneously control the upper clamping block 1302 and the lower clamping block 1303 to flip outward or rotate inward through the linkage effect, thereby being able to control the release or clamping of the roller handle 302.

[0036] When this embodiment is implemented, Figure 8 In the state shown, the control cylinder 1601 is in an extended state, and the upper clamping block 1302 and the lower clamping block 1303 are in closed contact. At this time, the roller handle 302 can be clamped and positioned, so that the winding assembly 3 can be ensured to be stable during winding. When the wound film needs to be removed, the control cylinder 1601 is adjusted to retract. Therefore, the control cylinder 1601 can drive the linkage plate 1602 to move when it retracts, thereby driving the upper pull plate 1603 and the lower pull plate 1604 to move through the linkage plate 1602. Since the upper pull plate 1603 is arranged at the placement port 17 and its two ends are rotatably connected with the upper end of the linkage plate 1602 and the upper clamping block 1302 respectively, the lower pull plate 1604 is arranged in the placement opening 17 and its two ends are rotatably connected with the lower end of the linkage plate 1602 and the lower clamping block 1303 respectively, so that the upper pull plate 1603 can drive the upper clamping block 1302 to rotate upward, and the lower pull plate 1604 can drive the lower pull plate 1604 to rotate downward, at this time, the upper clamping block 1302 and the lower clamping block 1303 are opened enough and leave enough space between them and the roller handle 302, so that the film can be easily removed.

[0037] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made to the present invention within the spirit and scope defined by the claims, but they will all fall within the scope of protection of the present invention.
