DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0033] Reference Figure 1 The wrapping film device 100 in the embodiment comprises a support frame 10 and a wrapping film cylinder fixing part 20.

[0034] The support frame 10 is provided with a roller 11 at the bottom.

[0035] Reference Figure 2 The wrapping film cylinder fixing part 20 is used for sleeving the wrapping film cylinder 200 and is fixedly arranged in the support frame 10 and comprises first cylinder shafts 21 and second cylinder shafts 22 arranged vertically and spaced apart.

[0036] Specifically, the film winding cylinder 200 can be quickly assembled and taken by the first cylinder shaft 21 and the second cylinder shaft 22. When the goods are wound with the film, the operator can hold the support frame 10 and move around the goods to wrap the film around the goods on the side of the goods.

[0037] The bottom of the first cylinder shaft 21 and the second cylinder shaft 22 is also provided with a pad 23. In this embodiment, the pad 23 is made of nylon material. When the film winding cylinder 200 is assembled on the first cylinder shaft 21 and the second cylinder shaft 22, the bottom of the film winding cylinder 200 is correspondingly placed on the pad 23. When the film is wound around the goods to drive the film winding cylinder 200 to rotate around the first cylinder shaft 21 and the second cylinder shaft 22, the pad 23 can reduce the rotating resistance of the bottom of the film winding cylinder 200, so that the film can be smoothly pulled out to ensure the smooth operation of the film winding operation.

[0038] Reference Figure 2 and Figure 3 The film winding cylinder fixing part 20 is provided with a plurality of film winding cylinder fixing parts 20 which are sequentially fixed in the support frame 10 along the height direction.

[0039] Specifically, the number of film winding cylinder fixing parts 20 in the support frame 10 can be set according to the height of the goods to be wound, so that a plurality of film winding cylinders 200 can be correspondingly assembled on the film winding cylinder fixing parts 20 arranged along the height direction to cover the goods at the corresponding height. Then, the support frame 10 can be moved around the goods to simultaneously perform the film winding operation on the entire goods, and the operator does not need to stretch his hand to operate at a high place or bend down to operate at a low place, which can greatly improve the film winding efficiency and effectively reduce the working time and fatigue of the operator.

[0040] In this embodiment, the film winding cylinder fixing part 20 is provided with three film winding cylinder fixing parts 20 which are correspondingly arranged at different heights to assemble three film winding cylinders 200 to perform the overall film winding on the goods at the corresponding height.

[0041] Reference Figure 2 and Figure 4 The film winding cylinder 200 is assembled outside the first cylinder shaft 21 and the second cylinder shaft 22, and the first cylinder shaft 21 and the second cylinder shaft 22 are provided with a tension adjusting unit 30 which is configured to adjust the spacing between the first cylinder shaft 21 and the second cylinder shaft 22.

[0042] Specifically, the spacing between the first cylinder shaft 21 and the second cylinder shaft 22 is adjusted by the tension adjusting unit 30, so that the friction resistance between the first cylinder shaft 21 and the second cylinder shaft 22 and the inner wall of the film winding cylinder 200 can be correspondingly adjusted to adjust the tightness of the winding.

[0043] When the spacing distance increases, the inner wall of the film winding cylinder 200 sleeved in the film winding cylinder fixing portion 20 will be more closely attached to the outer side of the first cylinder shaft 21 and the second cylinder shaft 22, the contact pressure increases, and the frictional resistance increases. When the goods are wound, a greater resistance needs to be overcome to rotate the film winding cylinder 200 to pull out the film around the film winding cylinder 200, thereby increasing the tension of the film during winding, and the winding tightness is improved. Conversely, when the spacing distance decreases, the tension of the film during winding can be correspondingly reduced, and the winding tightness is reduced. The tension adjusting unit 30 can quickly adjust the tension of the film during winding, flexibly adapt to the differentiated needs of different goods for the film winding tightness, and effectively improve the applicability of the film winding device.

[0044] Reference Figure 6 The tension adjusting unit 30 includes a screw 31, a disc nut 32, and a positioning block 33.

[0045] The positioning block 33 is fixedly arranged in the inside of the first cylinder shaft 21, the screw 31 is fixedly connected to the second cylinder shaft 22 at the screw cap end, the threaded screw rod of the screw 31 is arranged through the first cylinder shaft 21 and is movably inserted into the positioning block 33.

[0046] The disc nut 32 is screwed on the exposed threaded screw rod and is tightly arranged on the outer surface of the first cylinder shaft 21. The axial movement of the threaded screw rod is controlled by screwing the disc nut 32, and the spacing distance between the first cylinder shaft 21 and the second cylinder shaft 22 is correspondingly increased or decreased.

[0047] In this embodiment, the tension adjusting unit 30 is composed of the screw 31, the disc nut 32, and the plastic positioning block 33. By screwing the disc nut 32 tightly on the outer surface of the first cylinder shaft 21, the rotation of the thread between the disc nut 32 and the threaded screw rod is converted into axial movement, thereby driving the threaded screw rod to move axially and driving the second cylinder shaft 22 to move away from or close to the first cylinder shaft 21, so as to increase or decrease the spacing distance between the first cylinder shaft 21 and the second cylinder shaft 22.

[0048] The tension adjusting unit 30 in this embodiment has a simple structure, low cost, and is easy to maintain. The operator only needs to rotate the disc nut 32 to quickly adjust the film winding tightness without the need for additional tools or complex operations.

[0049] Further, the tension adjusting unit 30 is arranged at the top position of the first cylinder shaft 21 and the second cylinder shaft 22. The length of the first cylinder shaft 21 and the second cylinder shaft 22 in the height direction is greater than that of the film winding cylinder 200. When the film winding cylinder 200 is sleeved on the first cylinder shaft 21 and the second cylinder shaft 22, the tension adjusting unit 30 remains exposed. Therefore, after the film winding cylinder 200 is sleeved and installed, the spacing distance between the first cylinder shaft 21 and the second cylinder shaft 22 can also be quickly adjusted by the tension adjusting unit 30.

[0050] The bottom of the support frame 10 is also provided with a power boosting unit, including a drive wheel 41 arranged at the bottom of the support frame 10, a driver 42 in communication connection with the drive wheel 41 and controlling the action of the drive wheel 41, and a battery (not shown in the figure) in electrical connection with the drive wheel 41 and the driver 42.

The driver 42 is in communication connection with the drive motor through cable or wireless communication, etc., and correspondingly controls the power and rotation direction of the drive motor, so as to correspondingly control the boost size and rotation direction of the drive wheel 41.

[0052] Further, the outer side of the support frame 10 is also provided with a control handle 50, which is in communication connection with the driver 42. The control handle 50 is provided with a boost size control unit and a boost direction control unit, which correspondingly generate control signals and send them to the driver 42. The driver 42 controls the boost size and boost direction of the drive wheel 41 according to the control signals, so as to meet the needs of different application scenarios.

[0053] In this embodiment, the bottom of the control handle 50 is provided with a mounting seat, which is fixed to the outer side of the support frame 10. The control handle 50 is arranged at the middle position of the support frame 10 in the height direction, so as to be convenient for the operator to hold and use.

[0054] Further, the mounting seat is arranged in a detachable structure, so as to be convenient for the operator to adjust the mounting position of the control handle 50 according to different holding operation needs.

[0055] In this embodiment, the boost size control unit is arranged as follows: a rotating shaft is arranged in the control handle 50, so that the control handle 50 can be held and rotated. At the same time, an angle sensor is arranged inside the control handle 50 to detect the rotation degree, which is linearly corresponding to the output power of the drive motor, i.e. the boost size of the drive wheel 41. The driver 42 controls the boost size of the drive wheel 41 according to the received rotation degree, so that the boost size of the drive wheel 41 can be quickly controlled by rotating the control handle 50.

[0058] It can be understood that the structure of the assist force direction control unit in the control handle 50 can meet the corresponding control of the assist force direction of the driving wheel 41, and the setting form of the assist force direction control unit is not limited specifically. For example, the switching button can be set as an arch-shaped flip button, and by pressing different ends, a forward / reverse signal can be triggered accordingly; or the switching button can also be set as two independent buttons corresponding to forward assist force or reverse assist force, and the assist force direction is selected by pressing different buttons; or it can also be set as a touch screen form, and the assist force direction selection interface is set in the touch screen, and the corresponding assist force direction can be selected by the touch screen.
