Description
Technical Field
[0001] The utility model relates to the technical field related to shearing components, in particular to a shearing component for a reflective film. Background Art
[0002] The existing announcement number is: CN220431806U, a shearing assembly for reflective film. The reflective film is supported by a roller, so that the reflective film is prevented from contacting with the lower blade when the reflective film is rapidly moved and rolled up, thereby preventing the lower blade from scratching the reflective film. At the same time, the spring is slidably connected with the first slide groove and the first slider, so that the roller can give the roller space to make way, so that the roller can be displaced, so that the upper blade and the lower blade are closed to cut off the reflective film, effectively solving the problem in the prior art that when the winding shaft rotates at a high speed, the reflective film will be scratched when it contacts with the lower blade, thereby damaging the reflective film.
[0003] Although the above-mentioned existence can avoid the lower blade from contacting the reflective film during rapid winding by setting a roller, the reflective film is a flexible material and the properties of the material cause the reflective film to bend downward. When the reflective film is conveyed to the side of the upper blade body, it may bend downward due to the properties of the material, and the reflective film falls, resulting in the upper and lower blades being unable to cut the reflective film, affecting the cutting work and the cutting efficiency. Utility Model Content

[0012] Preferably, a motor is mounted on the first base, and an output end of the motor is mounted on the unwinding roller.
[0013] The beneficial effects of the utility model are:
[0014] 1. Through the cooperation between the double-headed threaded rod, the plate body and the frame body, the reflective film is transported to the upper blade and the lower blade through the first roller, and the double-headed threaded rod is rotated to drive the two sets of sliders connected by the thread to move horizontally. The two sets of sliders drive the corresponding blocks to move downward through the connecting rods respectively, and the blocks drive the second roller connected to the frame body to move downward until it fits with the reflective film. When the reflective film slides out of the plate body onto the slideway after being transported by the first roller and the second roller, an opening is opened on the slideway, and the top of the opening is at the same horizontal line as the top of the lower blade, so as to avoid the reflective film from contacting the lower blade to a certain extent. The first electric push rod is started to drive the upper blade to move downward, and the upper blade cooperates with the lower blade placed horizontally at the opening opened on the slideway to complete the cutting of the reflective film. The cut reflective film slides down and is collected through the inclined slideway. The design of the first roller, the second roller and the slideway prevents the reflective film from bending due to the nature of the material during transportation, which affects the cutting work of the upper and lower blades on the reflective film. At the same time, it also avoids the reflective film from contacting the lower blade after bending, thereby improving the cutting efficiency to a certain extent.
[0015] 2. Through the cooperation between the second electric push rod, the first base and the second base, the second electric push rod is started to drive the connected second base to slide upward. After the second base moves a certain distance, the sliding connected unwinding roller can be removed, which makes it more convenient to replace and install the unwinding roller and improve the cutting work efficiency.

DETAILED DESCRIPTION
[0022] 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.

The two groups of blocks 10 are connected to the frame 3. The blocks 10 drive the second roller 6 on the frame 3 to move downward until it fits with one end of the reflective film. Two groups of first electric push rods 11 are installed on the frame 3. The two groups of first electric push rods 11 are connected to the upper blade 12. The first electric push rods 11 drive the upper blade 12 to move up and down. A slideway 14 is connected to one end of the plate 4, and a lower blade 13 is connected to one end of the slideway 14. The cutting work of the reflective film is completed by cooperating with the downwardly moved upper blade 12. When the reflective film moves on the slideway 14 and is cut, the failure to cut the reflective film due to downward bending can be avoided, thereby improving work efficiency.
[0024] In this embodiment, a first base 15 is connected to the bottom plate 1, and a reel 19 is slidably connected to one end of the first base 15. A second base 17 is slidably connected to the bottom plate 1, and the second base 17 is slidably connected to the reel 19. A second electric push rod 18 is installed on the bottom plate 1, and one end of the second electric push rod 18 is connected to the second base 17. When the second electric push rod 18 is started, the connected second base 17 is driven to slide upward. After the second base 17 moves a certain distance, the slidably connected reel 19 can be removed, and the reel 19 that has been cut can be replaced more conveniently. A groove is provided on the plate body 4, and the frame body 3 is slidably connected to the groove. The groove serves as a guide for the frame body 3. One end of the slideway 14 is designed to be inclined and a baffle is installed. When the cut reflective film slides down and is collected through the slideway 14, the reflective film is prevented from sliding down from one end and the other end of the slideway 14. The slideway 14 is designed with an opening, and the top of the lower blade 13 is at the same horizontal line as the top of the opening, which can avoid the reflective film from contacting the lower blade 13 to a certain extent, causing damage to the reflective film. Multiple groups of first rollers 5 are evenly distributed on the plate body 4, and multiple groups of second rollers 6 are evenly distributed on the frame body 3. A motor 16 is installed on the first base 15, and the model of the motor 16 can be selected according to actual conditions. The output end of the motor 16 is installed with the unwinding roller 19, and the motor 16 drives the unwinding roller 19 to rotate.
[0025] The working principle of this embodiment is as follows: when in use, the motor 16 is started to drive the unwinding roller 19 to work, and the reflective film is transported to the slideway 14 through the first roller 5. At the same time, the double-headed threaded rod 7 is rotated to drive the slider 8 to move horizontally. Through the transmission cooperation of the slider 8, the connecting rod 9 and the block 10, the frame 3 is driven to move downward, and the second roller 6 connected thereto also moves downward until it fits with one end of the reflective film, which can make the process of conveying the reflective film more stable. When the reflective film moves to the slideway, according to the actual required length of the reflective film to be sheared, the first electric push rod 11 is started to drive the upper blade 12 to move downward, and cooperate with the lower blade 13 to shear the reflective film. The sheared reflective film slides down through the inclined slide 14, which is convenient for collecting the reflective film. When replacing the unwinding roller 19, the second electric push rod 18 can be started to drive the second base 17 to move longitudinally. After moving to a certain position, the unwinding roller 19 slidably connected to the first base 15 and the second base 17 can be removed, and the removal and installation of the unwinding roller 19 are more convenient.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
