DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A protective film winding device comprises a winding frame 1, a winding roller 2 is connected to the inner side of the winding frame 1, and a film roll 3 is sleeved on the outer side of the winding roller 2. A motor is installed inside the winding frame 1 to drive the winding roller 2 to rotate, thereby completing the winding operation. The specific principle is the existing technology and will not be described in detail here. A mounting groove 4 is opened at the bottom of the winding frame 1, and a cylinder 5 is installed inside the mounting groove 4, and the end of the cylinder 5 extends to the outside of the cylinder 5 and is connected to a movable plate 6. The extension and retraction principle of the cylinder 5 is the existing technology and will not be described in detail here. Through the extension and retraction of the cylinder 5, the movable plate 6 and the winding roller 2 can be driven to move closer or farther away, so that it is convenient for the staff to remove the film roll 3 on the winding roller 2 and replace it with a new set of winding cores.

[0023] Further, see Figure 2 It can be known that a slot is provided at the bottom end of the movable plate 6, and rollers 7 are installed equidistantly inside the slot. The rollers 7 installed inside the slot can ensure smooth sliding of the movable plate 6.

[0024] Further, see Figure 2 and Figure 3 It can be known that a cross bar 8 is provided at the top of the movable plate 6, and a limiting plate 9 is symmetrically distributed on the lower side of the cross bar 8, and the front and rear ends of the limiting plate 9 are respectively connected with fixed blocks 10, and the side of the fixed blocks 10 close to each other is in contact with the cross bar 8, and the interior of the front fixed block 10 is respectively inserted with insertion rods 11, and the front of the insertion rod 11 is connected with a linkage block 12, and the interior of the cross bar 8 is laterally equidistantly provided with positioning grooves that are compatible with the insertion rods 11. When in use, through the mutual cooperation of the insertion rods 11 and the linkage block 12, the spacing between the two groups of limiting plates 9 can be appropriately adjusted according to the width of the film roll 3, so as to realize the limiting operation on the two ends of the film roll 3, thereby effectively ensuring the neatness of the film roll 3 during the winding process.

[0025] Further, see Figure 3 and Figure 4 It can be seen that the bottom end of the cross bar 8 is connected to a guide bar 14, and the top end of the limit plate 9 is provided with a sliding groove adapted to the guide bar 14. The mutual cooperation between the guide bar 14 and the spring 13 can ensure the stability of the limit plate 9 during the lateral movement.

[0026] Further, see Figure 3 It can be known that a spring 13 is connected to the inner side of the linkage block 12, and the other end of the spring 13 is connected to the fixed block 10. When in use, the spring 13 connected to the inner side of the linkage block 12 can ensure that the inserted rod 11 is tightly engaged in the positioning groove inside the cross bar 8.

[0027] Further, see Figure 2 and Figure 4It can be known that an extension rod 15 is connected to the lower side of the cross bar 8, a receiving groove adapted to the extension rod 15 is provided at the top of the movable plate 6, a positioning rod 16 is laterally inserted at the top of the movable plate 6, and limiting grooves adapted to the positioning rod 16 are equidistantly provided inside the extension rod 15. When in use, the height of the cross bar 8 and the limiting plate 9 can be adjusted by the mutual cooperation of the extension rod 15 and the positioning rod 16, thereby meeting the winding requirements of the film roll 3 with a larger diameter, so as to effectively improve the applicability of the device during use.

[0028] Further, see Figure 1 It can be known that a circular ring is connected to the side of the movable plate 6 at a position corresponding to the winding roller 2, and balls are evenly distributed on the inner wall of the circular ring. By setting the circular ring and the balls, the right end of the winding roller 2 can be supported. When winding, the right end of the winding roller 2 will be engaged in the circular ring and will contact with the balls during the rotation, thereby effectively ensuring the stability of the winding roller 2 during the winding process.

[0029] Working principle: When the utility model is in use, the staff can first start the cylinder 5, so that it pushes the movable plate 6 to move to the right and away from the winding roller 2. At this time, the staff can insert the winding core to the outside of the winding roller 2. After the insertion is completed, the staff can drive the movable plate 6 to reset again through the operation of the cylinder 5, and then according to the length of the film roll 3, by pulling the linkage block 12 in sequence, the insertion rod 11 can be driven to be pulled out from the inside of the cross bar 8. At this time, the staff can move the limiting plate 9 laterally to make it close to the end of the film roll 3, and then the staff can stop pulling the linkage block 12, so that the insertion rod 11 is reset by the elastic force of the spring 13 and embedded in the cross bar. The corresponding limit groove inside the rod 8 is used to realize the limiting operation of the limit plate 9. When the spacing between the two groups of limit plates 9 is adjusted to a distance that matches the width of the film roll 3, the staff can start the work of the machine body, and the motor arranged inside it can drive the rotation of the winding roller 2 to realize the winding operation of the protective film. During the winding process, the two groups of limit plates 9 are set to achieve the limiting of both sides of the winding film. In addition, after use, the staff can start the cylinder 5 again to make the film roll 3 pulled out from the outside of the winding roller 2, and engage a new group of winding cores to the outside of the winding roller 2 to complete the subsequent winding operation. The above is the entire working principle of the utility model.
