DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] Combine Figure 1-Figure 7 , a plastic wrap cutting device includes a frame 1, a fixing frame 2 and a bracket 3 are fixedly provided at the upper end of the frame 1, a motor 4 is fixedly provided on one side of the fixing frame 2, a connecting seat 5 is fixedly installed at the output end of the motor 4, a winding drum 6 is fixedly provided at one end of the connecting seat 5, a cutting structure 7 is provided inside the bracket 3, the cutting structure 7 includes a stable plate 8 slidingly arranged inside the bracket 3, buffer grooves 9 are provided on both sides of the front end of the bracket 3, a vertical rod 10 is fixedly provided inside the buffer groove 9, two ends of the stable plate 8 are respectively connected to the inside of the two buffer grooves 9 and are sleeved on the outer wall of the vertical rod 10, a spring 11 is fixedly provided at the lower end of the stable plate 8 located on the outer wall of the vertical rod 10, a cylinder 12 is fixedly provided at the upper end of the bracket 3, a cutting knife 13 is fixedly provided at the output end of the cylinder 12, a groove 14 is provided at the upper end of the stable plate 8 located at the lower end of the cutting knife 13, and the corner above the rear end of the stable plate 8 is arc-shaped.

[0026] See Figure 3 and Figure 7 , it is further obtained that the internal thread of the fixed frame 2 is provided with a second screw rod 19, one end of the second screw rod 19 is rotatably installed with a movable plate 20, one side of the movable plate 20 is rotatably installed with an insertion rod 21, the shape of the groove 14 is rectangular, two sets of limit cylinders 15 are rotatably installed inside the bracket 3, and one end of the second screw rod 19 is fixedly provided with a handle.

[0027] Specifically, the second screw 19 is used to rotate and install the movable plate 20, and the movable plate 20 is used to rotate and install the insertion rod 21. The insertion rod 21 enters the inner wall of the winding drum 6, and the two sets of limiting cylinders 15 are used to limit the cling film to be rolled up.

[0028] Example 2

[0029] See Figure 6 On the basis of Example 1, it is further obtained that a clamping column 16 is fixedly provided on one side of the connecting seat 5, a first screw rod 17 is threadedly provided on the upper end of the connecting seat 5, the lower end of the first screw rod 17 is rotatably connected to the extrusion plate 18, and the winding drum 6 is sleeved on the outer wall of the clamping column 16.

[0030] Specifically, the clamping column 16 facilitates the sleeve installation of one end of the winding drum 6, and the first screw rod 17 is used to adjust the position of the extrusion plate 18, and the extrusion plate 18 is used to squeeze to the outer wall of the winding drum 6 to achieve a stable installation of the winding drum 6 and the connecting seat 5.

[0031] In the actual operation process, the cling film to be wound passes through between the two sets of limiting cylinders 15 and is fixed on the upper end of the winding drum 6. At this time, due to the action of the spring 11, the upper end of the stabilizing plate 8 contacts the lower end of the cling film, and the motor 4 is started, so that the motor 4 drives the connecting seat 5 to rotate, thereby driving the winding drum 6 to rotate, and the cling film is wound. When it needs to be cut after the winding is completed;

[0032] The cylinder 12 is started, so that the cylinder 12 drives the cutting knife 13 to move downward, so that the cutting knife 13 cuts the plastic wrap and enters the groove 14, thereby achieving automatic and quick cutting. Even if the cutting knife 13 contacts the stabilizing plate 8, the stabilizing plate 8 presses the spring 11, so that the stabilizing plate 8 moves downward, which can protect the cutting knife 13.

[0033] After the cutting is completed, the second screw rod 19 is rotated to move the insertion rod 21 out from the inside of the winding drum 6, and the first screw rod 17 is rotated so that the first screw rod 17 drives the extrusion plate 18 to move upward, thereby separating the extrusion plate 18 from the winding drum 6, pulling the winding drum 6, and realizing the rapid removal of the winding drum 6.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
