[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-3As shown, a PVC film winding mechanism with an anti-deviation structure includes a U-shaped frame 1, a winding assembly 6, and a limiting assembly 7. A lifting plate 2 for support is bolted to the inner wall of the U-shaped frame 1. A cylinder 3 for driving the pressure roller 4 to rise and fall is connected through the lifting plate 2. The output end of the cylinder 3 is bolted to the pressure roller 4 for pressing. A support roller 5 for supporting the PVC film is provided below the pressure roller 4. The support roller 5 is connected through the bearing to the inner wall of the U-shaped frame 1. A winding assembly 6 for winding is provided on the back of the U-shaped frame 1. A limiting assembly 7 for limiting is provided on the outer side of the winding assembly 6. The winding assembly 6 includes a variable frequency motor 601 embedded in the inner wall of the U-shaped frame 1. The output end of the variable frequency motor 601 is connected to a drive gear 602 via a coupling. A driven gear 603 is meshed above the drive gear 602. The drive gear 602 and the driven gear 603 are used for transmission. The driven gear 603 is connected to the rear part of the inner wall of the U-shaped frame 1 through a bearing. A conductive slip ring 604 for power transmission is bolted to the outside of the driven gear 603. The conductive slip ring 604 is bolted to the back of the U-shaped frame 1.

[0025] In this embodiment, the pressure roller 4 is composed of a rotating roller connected inside the bracket. The PVC film is placed between the support roller 5 and the pressure roller 4. The cylinder 3 is started to drive the pressure roller 4 to move downward, squeezing the PVC film onto the support roller 5. The squeezing force is adjusted by adjusting the distance between the pressure roller 4 and the support roller 5, thereby adjusting the tension. A PLC controller is installed at the front of the U-shaped frame 1 to link with the electrical components of the entire equipment for central control. The variable frequency motor 601 is started by the motor controller, which drives the drive gear 602 to rotate. The drive gear 602 drives the driven gear 603 to rotate. The driven gear 603 is hollow inside and is used to house the servo motor a606. The inner cylinder of the conductive slip ring 604 is installed on the driven gear 603, and the outer cylinder of the conductive slip ring 604 is installed on the back of the U-shaped frame 1. When the driven gear 603 and the hollow shaft 605 rotate, they provide power to the servo motor a606.

[0026] In one embodiment, such as Figure 5 As shown, the front of the driven gear 603 is bolted to a hollow shaft 605 for supporting components. The back of the hollow shaft 605 is connected to a servo motor a606 for providing power via a motor mount. The servo motor a606 is located inside the driven gear 603, and the output end of the servo motor a606 passes through the inner wall of the hollow shaft 605 and is connected to a bidirectional threaded rod 607 via a coupling. The bidirectional threaded rod 607 is used to drive the two sets of sliders 608 to rotate. The bidirectional threaded rod 607 is connected to the inner wall of the hollow shaft 605 via a bearing.

[0027] The roll is connected to the hollow shaft 605 through the openings at the front and rear of the U-shaped frame 1. One end of the PVC film is attached to the roll. When the driven gear 603 drives the hollow shaft 605 and the roll to rotate, the PVC film is wound up. When winding the PVC film, it is necessary to ensure that the diameter of the wound PVC film is smaller than the opening at the front of the U-shaped frame 1. The servo motor a606 is started through the motor controller. The servo motor a606 drives the bidirectional threaded rod 607 to rotate on the inner wall of the hollow shaft 605.

[0028] In one embodiment, such as Figure 5 and Figure 6 As shown, the outer side of the bidirectional threaded rod 607 is equipped with a slider 608 for driving the connecting plate 609 to move. The connecting plate 609 for transmission is rotatably connected inside the slider 608. The other end of the connecting plate 609 is rotatably connected to a top plate 610 through an ear plate. The top plate 610 is used to limit the movement of the drum. The top plate 610 passes through the inner wall of the hollow shaft 605.

[0029] The top plate 610 and connecting plate 609 are provided in three sets. When the bidirectional threaded rod 607 rotates, it drives the two sets of sliders 608 to move closer to each other. The sliders 608 push the connecting plate 609 to rotate between the top plate 610 and the sliders 608, thereby pushing the top plate 610 to move outward from inside the hollow shaft 605. The extended top plate 610 squeezes the inner wall of the drum, and the drum is tightened from the inside by the top plate 610, thereby fixing the drum on the hollow shaft 605, which facilitates the change of the drum.

[0030] In one embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the limiting component 7 includes a servo motor b701 connected to the back of the U-shaped frame 1 via a motor mount. The servo motor b701 is used to provide power. The output end of the servo motor b701 passes through the inner wall of the U-shaped frame 1 and is connected to a lead screw 702 via a coupling. The lead screw 702 is used to drive the annular shell 703 to move. The lead screw 702 is connected to the inner wall of the U-shaped frame 1 via a bearing. The outer side of the lead screw 702 is driven by an annular shell 703 for supporting components. A guide rod 704 is also provided inside the annular shell 703. The guide rod 704 is connected to the inner wall of the U-shaped frame 1.

[0031] Two sets of servo motors b701, lead screws 702, and slide bars 704 are provided. The two sets of servo motors b701 are controlled to rotate synchronously by the HJ-03A intelligent motion controller, which drives the two sets of lead screws 702 to rotate synchronously, thereby driving the annular shell 703 to move back and forth along the two sets of slide bars 704. The distance between the baffle 707 and the inner wall of the U-shaped frame 1 is adjusted according to the width of the PVC film.

[0032] In one embodiment, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the front of the annular shell 703 is connected to a servo motor c705 for providing power via a motor mount. The output end of the servo motor c705 passes through the inner wall of the annular shell 703 and is connected to a spur gear 706 via bolts. The spur gear 706 is connected to the inner wall of the annular shell 703 via a bearing. The back of the spur gear 706 is connected to a baffle 707 for limiting the PVC film via bolts. The outer side of the spur gear 706 is meshed with an internal gear ring 708 for transmission. The internal gear ring 708 is rotatably connected inside the annular shell 703.

[0033] The servo motor c705 is started by the motor controller, which drives the spur gear 706 and the baffle 707 to rotate. While the spur gear 706 is rotating, it drives the internal gear ring 708 to rotate. The internal gear ring 708 drives the other spur gears 706 and the baffle 707 to rotate together, moving the baffle 707 away from the hollow shaft 605. Then, the roll for winding the PVC film is sleeved on the hollow shaft 605. Then, the servo motor c705 is started to rotate in the opposite direction, so that the baffle 707 abuts against the servo motor c705, thereby blocking the PVC film and keeping the PVC film between the baffle 707 and the inner wall of the U-shaped frame 1, thus limiting the PVC film and preventing it from shifting during the winding process.

[0034] The above embodiment discloses a PVC film winding mechanism with an anti-offset structure. The mechanism involves starting a servo motor c705 to move a baffle 707 away from the hollow shaft 605, then attaching a roll to the hollow shaft 605. A servo motor a606 then drives a bidirectional threaded rod 607 to support the roll. A servo motor b701 then moves the baffle 707 closer to the front of the roll. As the servo motor c705 rotates in the opposite direction, the baffle 707 abuts against the outside of the roll. The PVC film then passes between the pressure roller 4 and the support roller 5 and is adhered to the roll. A cylinder 3 then drives the pressure roller 4 to press the PVC film onto the support roller 5. A variable frequency motor 601 then rotates the hollow shaft 605 and the roll to wind up the PVC film. After winding, the servo motor c705 moves the baffle 707 away from the roll and the PVC film. A servo motor a606 then resets the top plate 610, and the roll with the PVC film wound around it is then unwound.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
