[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This embodiment provides a light strip cutting assembly, including a carrier housing 1 for carrying the light strip and a cutting device 5 for cutting the light strip. The cutting device 5 is fixedly installed on the top of the carrier housing 1. The top of the carrier housing 1 is provided with a transmission component for transmitting light strips of different sizes. A transmission roller 4 is rotatably installed on the top of the carrier housing 1. The transmission roller 4 is located between the cutting device 5 and the transmission component. After passing through the transmission component, the light strip passes under the transmission roller 4. The transmission roller 4 provides power and limits the light strip again, which helps to improve the convenience and stability of light strip transfer.

[0025] The transmission assembly includes a transmission cylinder 8 and a limiting disc 2. The transmission cylinder 8 is installed in the inner cavity of the bearing housing 1 via a chain drive. Both ends of the transmission cylinder 8 are equipped with rotating shafts, one end of which extends to the outside of the bearing housing 1. A drive motor is installed on the outside of the bearing housing 1. Both the power output end of the drive motor and the end of the rotating shaft extending to the outside of the bearing housing 1 are fixedly equipped with transmission gears. The two transmission gears are rotatably connected by a chain. Starting the drive motor will enable the transmission cylinder 8 to rotate.

[0026] The limiting plate 2 is fixedly sleeved on the outer wall of the transmission cylinder 8. The outer wall of the transmission cylinder 8 is slidably sleeved with a positioning plate 3 that matches the limiting plate 2. The top of the bearing housing 1 is provided with a receiving groove that matches the limiting plate 2 and the positioning plate 3. At the end of the limiting plate 2 near the positioning plate 3, multiple support plates 9 for supporting the light strip are fixedly installed in a ring. At one end of the positioning plate 3, an insertion groove that matches the support plate 9 is provided. The outer walls of the positioning plate 3, the limiting plate 2, and the support plate 9 all extend to the top of the bearing housing 1 through the receiving groove. When the light strip is placed between the positioning plate 3 and the limiting plate 2, the bottom of the light strip is in contact with the outer wall of the support plate 9. At the same time, the adjacent ends of the limiting plate 2 and the positioning plate 3 are in close contact with the two sides of the light strip. When the transmission cylinder 8 and the transmission roller 4 rotate simultaneously, they can provide power to the light strip, allowing the light strip to move along a straight line to the bottom of the cutting device 5.

[0027] The end of the support plate 9 away from the limiting plate 2 passes through the insertion slot and extends to the other end of the positioning plate 3. The inside of the transmission cylinder 8 is provided with a limiting component for limiting the positioning plate 3. When it is necessary to cut light strips of different sizes, the distance between the positioning plate 3 and the limiting plate 2 is adjusted by the limiting component. At this time, the support plate 9 slides inside the insertion slot until the distance between the positioning plate 3 and the limiting plate 2 is the same as the width of the light strip. Then, the adjustment of the limiting component is stopped, and the moved positioning plate 3 can be limited, thereby improving the efficiency of cutting light strips of different sizes and reducing the time and effort required for cutting light strips of different sizes.

[0028] Two support plates 9 are fixedly installed at the edge of the limiting plate 2. The outer walls of the two support plates 9 are curved, which helps to increase the contact area between the support plates 9 and the bottom of the light strip, thereby improving the stability and smoothness of the linear movement of the light strip.

[0029] Multiple limit plates 2 and positioning plates 3 are arranged in a straight line on the outer wall of the transmission cylinder 8. The multiple limit plates 2 and multiple positioning plates 3 are staggered. Multiple limit plates 2 and multiple positioning plates 3 can transmit multiple light strips at the same time, which is beneficial to improving the production speed of light strips.

[0030] In a preferred embodiment, the limiting assembly includes a transmission threaded rod 11 and a threaded collar 12. Multiple connecting blocks 14 are fixedly installed in a ring on the inner wall of the positioning disk 3. Multiple sliding grooves 10 that are adapted to the connecting blocks 14 are opened in a ring on the outer wall of the transmission cylinder 8. The end of the connecting block 14 away from the inner wall of the positioning disk 3 passes through the sliding groove 10 and extends into the inner cavity of the transmission cylinder 8. The positioning disk 3 can move along the longitudinal direction of the transmission cylinder 8 and rotate together with the transmission cylinder 8 under the cooperation between the connecting block 14 and the sliding groove 10.

[0031] A threaded collar 12 is rotatably mounted on one end of the connecting block 14 extending into the inner cavity of the transmission cylinder 8. A transmission threaded rod 11 is installed in the inner cavity of the threaded collar 12 via a threaded drive. Both ends of the transmission threaded rod 11 pass through the threaded collar 12 and are rotatably connected to the inner wall of the transmission cylinder 8. When the positioning disk 3 slides along the longitudinal direction of the transmission cylinder 8, the threaded collar 12 moves together with the positioning disk 3. When the positioning disk 3 rotates, the threaded collar 12 and the positioning disk 3 rotate relative to each other. When the transmission threaded rod 11 is rotated, the moving direction of the threaded collar 12 is controlled by the thread engagement, and the positioning disk 3 is positioned after the movement.

[0032] Both ends of the inner cavity of the transmission cylinder 8 are fixedly installed with drive bearings 13. Both ends of the transmission threaded rod 11 extend into the inner cavities of the two drive bearings 13. One end of the transmission threaded rod 11 passes through the drive bearing 13 and extends to the outside of the bearing housing 1. The end of the transmission threaded rod 11 away from the transmission gear extends to the outside of the bearing housing 1. The two drive bearings 13 facilitate the rotational connection between the two ends of the transmission threaded rod 11 and the transmission cylinder 8, allowing relative rotation between the transmission threaded rod 11 and the transmission cylinder 8, while improving the smoothness of the rotation of the transmission threaded rod 11.

[0033] A rocker arm 6 is fixedly installed at one end of the transmission threaded rod 11 that extends to the outside of the bearing housing 1. The transmission threaded rod 11 can be rotated by rotating the rocker arm 6, which increases the hand area of ​​the transmission threaded rod 11 and improves the convenience of rotating the transmission threaded rod 11.

[0034] A damping tube 7 is rotatably sleeved on the outer wall of the rocker arm 6. One end of the damping tube 7 is fixedly connected to the outer wall of the bearing housing 1. The damping tube 7 can increase the resistance when the rocker arm 6 rotates, thereby increasing the stability of the rocker arm 6 when it is stationary.

[0035] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
