[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a polypropylene film cutting device of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, a polypropylene film cutting device of the utility model comprises an operating table 19 and a cutting knife 13. The cutting knife 13 is arranged on the top of the operating table 19. The operating table 19 is connected to a plate body 6 via a rotating shaft. The top of the plate body 6 is fixedly connected to a frame body 7. A slider 11 is embedded in the interior of the frame body 7. A shaft seat 12 is arranged on the side of the slider 11. Due to the installation of the shaft seat 12, it is convenient to connect the slider 11 and the cutting knife 13. The shaft seat 12 is connected to the cutting knife 13 via a bearing. A frame body 18 is arranged on the outside of the shaft seat 12. A pull rod 8 is arranged on one side of the frame body 18. Due to the provision of the pull rod 8, it is convenient to pull the cutting knife 13 to move inside the frame body 7.

[0027] A sliding rod 3 is provided at the bottom of the operating table 19, and the number of the sliding rods 3 is provided in four groups. The outside of the sliding rod 3 is sleeved with a sleeve 2, and a base plate 1 is provided at the bottom of the sleeve 2. The outside of the sleeve 2 is fixedly connected to an internal threaded seat 4, and the internal threads of the internal threaded seat 4 are connected to a threaded pressure rod 5. Due to the installation of the internal threaded seat 4 and the threaded pressure rod 5, it is convenient to fix the position of the sliding rod 3 with the adjusted height.

[0028] A short rod 20 is provided on one side of the sliding rod 3, and a long rod 21 is provided on the other side of the sliding rod 3. The short rod 20 and the long rod 21 are respectively provided in two groups. The installation of the short rod 20 and the long rod 21 can play a role of fixed support for the connection between the sliding rods 3.

[0029] The frame 7 has a slide groove 10 disposed inside. The slide groove 10 is symmetrically distributed. A slider 11 is embedded inside the slide groove 10. The installation of the slider 11 and the slide groove 10 makes it convenient for the cutting knife 13 to move.

[0030] A handle 17 is provided on one side of the frame 7, a magnetic block 15 is fixedly connected to the bottom of the frame 7, a metal plate 14 is provided on the top of the operating table 19, and the magnetic block 15 absorbs the metal plate 14 through magnetic force. Since the metal plate 14 and the magnetic block 15 are installed, the position of the frame 7 is easily fixed through magnetic absorption.

[0031] The top of the operating table 19 is inlaid with a backing plate 9, and the outside of the pull rod 8 is sleeved with an anti-slip sleeve 16. Due to the installation of the backing plate 9, the cutting knife 13 can play a protective role when cutting back and forth on the top of the operating table 19.

[0032] The working principle of the polypropylene film cutting device is as follows: when using the film cutting device, the device body needs to be moved to a suitable position first, and then according to the staff's requirements for the operating height, when the height requirement is not high, only the frame body 7 needs to hold the handle 17, and then the frame body 7 is slightly lifted to allow the film to pass through the bottom of the cutting knife 13, and then the frame body 7 is put down to allow the magnetic block 15 at the bottom to magnetically absorb the top of the metal plate 14, and then the film can be cut, and the anti-slip sleeve 16 outside the pull rod 8 needs to be held, and the cutting knife 13 inside the frame body 18 is pulled back and forth, so that The film can be cut. Since the slider 11 is embedded inside the frame 7, it is faster to move and is not easily affected by foreign objects during cutting. It is simpler to operate, saves time and effort. Secondly, when the staff needs to change the height of the operating table 19, first reverse the external fastening plate of the internal threaded seat 4, then lift the operating table 19 to a suitable position, and then turn the threaded pressure rod 5 to fix its position on the sliding rod 3. This not only facilitates the staff's need to adjust the height of the operating table 19, but also makes it more convenient to adjust the height and is more firmly fixed.

[0033] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
