Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a chemical safety material cutting device. Background Art

[0002] Chemical materials refer to various chemicals and chemical raw materials used for chemical production, laboratory research, industrial processing and other purposes. These materials can be solid, liquid or gas, with various properties and uses. Chemical materials are widely used in various fields, including medicine, agriculture, food processing, chemical industry, material science, etc. However, in the processing of chemical materials, some long strips or special-shaped materials need to be cut, which requires the use of cutting devices.

[0003] After searching, the existing Chinese patent announcement number is: CN219294071U, which provides a chemical safety material cutting device. The patent fixes protrusions at both ends of the lifting plate, and the bottom ends of the two protrusions are elastically inserted with fastening plates located below the cutting knife. During the movement of the lifting plate, the fastening plate at the bottom of the protrusion first contacts the chemical material and squeezes the first spring during the continuous movement, so that the elastic force of the first spring pushes the fastening plate to press and fix the chemical material. After that, the cutting knife contacts the chemical material and completes the cutting of the chemical material during the continuous downward movement, which is convenient for pressing and positioning the chemical material before cutting, thereby improving the stability of chemical material cutting.

[0004] Although the above patent can compress and position chemical materials, the above-mentioned chemical safety material cutting device still has the following problems: although the pressing and positioning part is provided with a corrosion-resistant block, the corrosion-resistant block only reduces the corrosion ability of corrosive chemicals and cannot completely isolate corrosion. Therefore, after long-term use, the pressing and positioning part still needs to be maintained and replaced. However, the fixed installation structure is not conducive to maintenance and replacement, which may waste replacement time and reduce production efficiency.

[0005] In view of the above problems, a chemical safety material cutting device is proposed. Utility Model Content

[0011] As a further description of the above technical solution: a second spring is sleeved on the outside of the telescopic rod, the top of the second spring is fixedly connected to the bottom of the upper fixed plate, and the bottom of the second spring is fixedly connected to the top of the lower fixed plate.

[0012] By adopting the above technical solution, the adaptable movement between the upper fixing plate and the lower fixing plate is achieved by the elasticity of the second spring.

[0013] As a further description of the above technical solution: the bottom of the transverse rotating block is fixedly connected with a positioning block, the bottom of the positioning block is rotatably connected with evenly distributed longitudinal rotating blocks, and the bottom of the longitudinal rotating block is fixedly connected with a corrosion-resistant block.

[0015] As a further description of the above technical solution: a cutting knife is arranged inside the lifting plate, and a hydraulic cylinder is fixedly connected to the top of the lifting plate.

[0016] By adopting the above technical solution, the lifting plate is moved up and down by the hydraulic cylinder, and the chemical material is cut by the cutting knife.

[0017] As a further description of the above technical solution: four evenly distributed clamping holes are opened on the left and right sides of the lifting plate, and the clamping rods are located inside the clamping holes.

[0018] By adopting the above technical solution, the upper fixing plate can be installed by inserting the clamping rod into the clamping hole, and it is convenient to disassemble.

[0019] As a further description of the above technical solution: an extrusion block is fixedly connected to the inner side of the clamping rod, and the outer wall of the extrusion block abuts against the outer wall of the extrusion head.

[0020] By adopting the above technical solution, the extrusion block is squeezed by the extrusion head to make the clamping rod expand outward, thereby completing the installation and fixation of the upper fixing plate.

[0021] As a further description of the above technical solution: a first spring is fixedly connected to the outward side of the clamping rod, and the first spring is fixedly connected to the inner wall of the shell.

[0022] By adopting the above technical solution, the elasticity of the first spring allows the clamping rod to quickly return to its original position when it is not squeezed by the squeezing head.
