[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural schematic diagram of an embodiment of a plastic sealing film winding device, including:

[0034] Please see Figures 1-5 This utility model provides a technical solution:

[0035] A film winding device includes a base 1. A square groove 18 is formed on the top of the base 1. A motor 29 is bolted to the inner wall of the square groove 18. The output shaft of the motor 29 is inserted into a telescopic rod 20. A retaining seat 21 is bolted to the top of the telescopic rod 20. An arc groove 22 is formed on the top of the retaining seat 21. A groove 23 is formed on one side of the retaining seat 21. A retaining plate 25 is engaged with the inner wall of the groove 23. A retaining cavity 26 is formed inside the retaining plate 25. A retaining groove 27 is formed on the inner wall of the retaining cavity 26. A corner block 28 is slidably connected to the inner wall of the retaining groove 27. A vertical block 33 is bolted to the top of the corner block 28. The inner wall of block 33 is connected to a retaining strip 34 via a damping bearing. One end of the retaining strip 34 is connected to a vertical plate 35 via a damping bearing. The side wall of corner block 28 is connected to a damper 32 via bolts. A spring 31 is sleeved on the outer circumference of the damper 32. The inner wall of square groove 18 is provided with a corner groove 29. The inner wall of corner groove 29 is engaged with corner block 28. The retaining seat 21 is lowered by telescopic rod 20, and the vertical rod 36 is pulled to move the retaining strip 34. At the same time, the damper 32 and spring 31 extend and retract, so that corner block 28 can be disengaged from corner groove 29. This facilitates the removal of the plastic seal film on the surface of roller 5, thereby achieving the purpose of convenient removal of plastic seal film.

[0036] The output shaft of motor 219 is coaxially connected to the lead screw via a coupling (rigid / flexible). The rotation of motor 219 drives the lead screw to rotate, which in turn causes the lead screw nut to drive the telescopic rod 20 to move linearly. This is existing technology, so in this article, motor 219 and telescopic rod 20 are used as references only.

[0037] It is worth noting that, in order to facilitate the winding operation of the plastic sealant, the top of the base 1 is bolted to a fixed seat 2, the side wall of the fixed seat 2 is bolted to a motor 3, the output shaft of the motor 3 is inserted into a roller 4, and a winding roller 5 is sleeved on the outer circumference of the roller 4. The motor 3 drives the roller 4, thereby facilitating the rotation of the winding roller 5, which in turn facilitates the winding operation of the plastic sealant.

[0038] Next, in order to maintain a good uniform speed buffering effect during the process of corner block 28 disengaging from corner groove 29, there are multiple springs 31 and dampers 32, which are equidistantly distributed. The top of the vertical plate 35 is connected to a vertical rod 36 by bolts, and a handle 37 is fixed to the top of the vertical rod 36. The inner wall of the locking cavity 26 is connected to a locking rod 30 by bolts, and the corner block 28 is sleeved on the outer circumference of the locking rod 30. There are multiple locking strips 34, which are symmetrically distributed. Through the structural design of dampers 32 and springs 31, it is easy to maintain a good uniform speed buffering effect during the process of corner block 28 disengaging from corner groove 29.

[0039] Meanwhile, in order to achieve the purpose of providing a plastic sealant suitable for various winding requirements, specifically, a fixing ring 7 is sleeved on the outer circumference of the roller 5. A fixing plate 9 is bolted to one side of the fixing ring 7. A fixing strip 10 is connected to the side wall of the fixing plate 9 through a damping bearing. A fixing groove 11 is opened on one side of the fixing strip 10. An installation ring 17 is bolted to one end of the fixing seat 2. An installation plate 16 is bolted to one side of the installation ring 17. An installation strip 15 is connected to the side wall of the installation plate 16 through a damping bearing. A fixing groove 11 is connected to one side of the installation strip 15 through a damping bearing. An installation block 12 is connected to one end of the fixing strip 10 through a damping bearing. Through the damping bearing connection design between the installation strip 15 and the fixing strip 10, and in conjunction with the installation block 12, the cross plate 13 expands its diameter at a uniform speed when the fixing ring 7 is displaced, thereby achieving the purpose of providing a plastic sealant suitable for various winding requirements.

[0040] Furthermore, in order to provide multi-directional support for the rolled-up plastic film, specifically, one end of the mounting block 12 is bolted to a horizontal plate 13. There are multiple horizontal plates 13, which are arranged in a ring shape. The surface of the horizontal plate 13 is adhered with an anti-slip pad 14, which is made of silicone. The ring-shaped horizontal plates 13 facilitate multi-directional support for the rolled-up plastic film.

[0041] It is worth noting that, in order to cooperate with the horizontal plate 13 to fix the plastic sealant, specifically, the outer circumference of the roller 5 is provided with an external thread 6, and the inner wall of the fixing ring 7 is provided with an internal thread 8. The internal thread 8 is threaded to the external thread 6. Through the structural design of the external thread 6 threaded to the internal thread 8, it is easier to make the fixing ring 7 move on the outer circumference of the roller 5, thereby making it easier to drive the fixing strip 10 on the inner wall of the fixing plate 9 to change the angle, which is beneficial to cooperate with the horizontal plate 13 to fix the plastic sealant.

[0042] Finally, in order to cooperate with the card holder 21 to fix the roller shaft 4, specifically, the top of the card holder 21 is connected to the card block 24 by a bearing, the bottom of the card block 24 is provided with an arc groove 22, and the side wall of the card block 24 is provided with a groove 23. Through the structural design of the card block 24, it is easy to cooperate with the card holder 21 to fix the roller shaft 4.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] The device or equipment models mentioned in this article may be as follows:

[0045] Motor 1: Y802-4;

[0046] Motor 2: YMD602.

[0047] Combination Figures 1-5 The specific usage process of the plastic sealing film winding device of this embodiment is as follows:

[0048] 1: When using this type of plastic sealant winding device, after the operator moves the base 1 to a suitable position, the plastic sealant to be wound is placed on the surface of the roller 5, and the motor 3 connected to the side wall of the fixed base 2 by bolts drives the roller shaft 4 to rotate, thereby facilitating the winding operation of the plastic sealant.

[0049] 2: When the inner diameter of the plastic sealant to be wound by the device is multiple, by rotating the fixing ring 7, the internal thread 8 can be threaded to the external thread 6, thereby making it easy to change the position of the fixing ring 7, so that the fixing plate 9 can drive the fixing strip 10 to change the angle. At the same time, the mounting strip 15 connected to the side wall of the mounting plate 16 through the damping bearing changes the angle, thereby driving the horizontal plate 13 to move, so that the diameter formed between the multiple horizontal plates 13 in a ring distribution can be changed, thereby achieving the purpose of plastic sealant suitable for multiple winding requirements.

[0050] 3: When the device needs to remove the plastic sealant, the vertical rod 36 is pulled by the handle 37, so that the vertical plate 35 can move through the damping bearing connected to the locking strip 34. At the same time, the corner block 28 moves on the outer circumference of the locking rod 30, i.e., in the horizontal direction, so that the corner block 28 can be disengaged from the corner groove 29. After the locking plate 25 is removed, the locking block 24 is opened through the bearing. The motor 2 19 connected to the inner wall of the square groove 18 by bolts drives the telescopic rod 20 to drive the locking seat 21 to descend, so that the roller 4 can be disengaged from the inner wall of the arc groove 22. This facilitates the removal of the plastic sealant on the surface of the roller 5, thereby achieving the purpose of convenient removal of the plastic sealant.

[0051] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
