[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a precision polyester film slitting device provided by this utility model.

[0026] Example 1:

[0027] Combination Figure 1-5 As shown, the present invention provides a precision slitting device for polyester film, comprising: a slitting machine body 100 and a curing component 200; the slitting machine body 100 includes a slide 101 movably mounted on one side, a slitting cylinder 102 fixedly mounted on the upper end of the slide 101, a slitting motor 103 fixedly mounted on the front end of the slitting cylinder 102, a slitting blade 104 fixedly mounted on the front end of the slitting motor 103, a mounting base 105 mounted on the front end of the slitting motor 103, and a polyester film roll 106 movably mounted on the outer end of the mounting base 105; the curing component 200 includes a curing box 201 movably mounted on the bottom of the slitting blade 104, a U-shaped tube 202 fixedly mounted inside the curing box 201, spray holes 203 arranged inside the U-shaped tube 202, a connecting pipe 204 fixedly connected to the bottom of the U-shaped tube 202, a cleaning liquid box 205 fixedly mounted on the outer end of the connecting pipe 204, and a curing component 206. The cleaning cotton 206 is movably installed inside the box 201. The lifting cylinder 207 is fixedly installed at the bottom of the maintenance box 201. An infusion pump 208 is also fixedly installed on the connecting pipe 204 and is fixed between the maintenance box 201 and the cleaning liquid box 205. A fixing plate 209 is also fixedly installed at the outer end of the cleaning cotton 206. A drain port 210 is also opened at the bottom of the maintenance box 201. A drain pipe 211 is fixedly installed at the bottom of the drain port 210. A fixing bracket 212 is also fixedly installed at the outer end of the lifting cylinder 207 and is fixed to the front end of the slide 101. A threaded hole 213 and a mounting hole 214 are respectively opened on one end of the maintenance box 201 and the fixing plate 209. Screws 215 are movably installed in both the threaded hole 213 and the mounting hole 214. A filling cap 216 is also threadedly connected to the top of the cleaning liquid box 205.

[0028] Specifically, the polyester film precision slitting device, also known as a polyester film slitting machine, is a precision mechanical device specifically used for cutting polyester film rolls. After the slitting blade 104 at the upper end of the slide 101 cuts the polyester film roll 106 on the mounting base 105, residues, glue, or other impurities from the polyester film will adhere to its outer end during the slitting process. The lifting cylinder 207 at the front end of the slide 101 can move the top curing box 201 to the bottom of the slitting blade 104. Through the slow rotation of the slitting blade 104 and the cleaning fluid delivered to both ends of the slitting blade 104 by the infusion pump 208, the slitting blade 104 is automatically, conveniently, and promptly cleaned and maintained after use. This ensures the slitting effect of the slitting blade 104 in subsequent uses and ensures that the slitting blade 104 remains clean. The cleaning solution in the maintenance box 201 is convenient to use. After cleaning, the cleaning solution can be easily discharged through the drain port 210 and drain pipe 211 at the bottom. The cleaning cotton 206 used to wipe the slitting blade 104 in the maintenance box 201 can also be easily disassembled and replaced through the front end of the maintenance box 201 if it is damaged. The spray holes 203 arranged inside the U-shaped tube 202 in the maintenance box 201 can ensure the uniformity of the cleaning solution sprayed on the lower two ends of the slitting blade 104, thereby ensuring a good cleaning effect. The cleaning cotton 206 installed in the maintenance box 201 is mainly used for wiping the sides of the slitting blade 104 after spray cleaning. The filling cap 216 installed on the top of the cleaning solution box 205 is mainly used for filling the cleaning solution after use.

[0029] Working principle and usage process of this utility model:

[0030] After the slitting blade 104 at the front end of the slitting cylinder 102 in the slitting machine body 100 has finished slitting the polyester film roll 106 at the outer end of the mounting base 105, the slitting cylinder 102 will drive the slitting blade 104 back to its initial position. The slitting motor 103 will slowly drive the front slitting blade 104 to rotate. At this time, the lifting cylinder 207 at the front end of the slide block 101 will be activated to drive the top curing box 201 to rise. After the curing box 201 is raised to the lower part of the slitting blade 104, the lower part of the slitting blade 104 will be in the U-shaped tube 202 and the cleaning cotton 206 inside the curing box 201. The infusion pump 208 between the maintenance box 201 and the cleaning solution box 205 will be activated to evenly spray the cleaning solution in the cleaning solution box 205 through multiple sets of spray holes 203 inside the U-shaped tube 202 to both ends of the lower part of the slitting blade 104, so as to clean the residue, glue or other impurities of the polyester film stuck to both ends of the slitting blade 104. After the lower ends of the slitting blade 104 are sprayed, they will be wiped through the cleaning cotton 206 while rotating slowly, thereby wiping away the impurities after cleaning, so as to ensure timely cleaning and maintenance of the slitting blade 104 after use and the cleaning and maintenance effect.
