[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0026] The following description, in conjunction with the accompanying drawings, describes the processing equipment for high-gloss PET film according to an embodiment of the present invention.
[0027] like Figures 1 to 4 As shown, the processing equipment for high-gloss PET film according to this utility model embodiment may include a base plate 100, an unwinding rack 200, a side plate 300, a slitting assembly 400, a heating assembly 500, and a winding assembly 600.
[0028] The unwinding frame 200 is mounted on the base plate 100, and the two side plates 300 are mounted opposite each other on the base plate 100. The slitting assembly 400, the heating assembly 500, and the two winding assemblies 600 are respectively mounted between the two side plates 300, wherein the two winding assemblies 600 are respectively staggered on the two side plates 300.
[0029] The roll of high-gloss PET film 700 is placed on the unwinding rack 200, and one end of the high-gloss PET film 700 passes between the slitting assembly 400 and the two heating assemblies 500 in sequence before being wound onto the two winding assemblies 600.
[0030] In one embodiment of this utility model, such as Figure 6 As shown, the slitting assembly 400 includes a cutting device 410 and a support roller 420 arranged vertically opposite each other.
[0031] To clearly illustrate the previous embodiment, in one embodiment of this utility model, the cutting device 410 includes a first drive motor 411, a transmission structure 412, a rotating shaft 413, and a cutting blade 414.
[0032] The first drive motor 411 is mounted on the side plate 300, the rotating shaft 413 is rotatably mounted between the two side plates 300 and is connected to the first drive motor 411 through the transmission structure 412, and the cutting blade 414 is mounted on the rotating shaft 413.
[0033] It should be noted that when the high-gloss PET film 700 is being cut, the high-gloss PET film 700 passes between the cutting blade 414 and the support roller 420. The relevant personnel start the first drive motor 411, which drives the rotating shaft 413 to rotate through the transmission structure 412, thereby realizing the rotation of the cutting blade 414. Through the rotation of the cutting blade 414, the high-gloss PET film 700 is cut.
[0034] like Figure 5 As shown, the heating assembly 500 includes a support rod 510, a heating plate 520, a connecting line 530, and a control panel 540.
[0035] The support rod 510 is fixedly installed between the two side plates 300, and the back of the heating plate 520 is slidably installed on the support rod 510 through the mounting buckle 521. The heating plate 520 is electrically connected to the control panel 540 through the connecting line.
[0036] It should be noted that the cut of the high-gloss PET film 700 passes between the two heating plates 520.
[0037] like Figure 7As shown, the winding assembly 600 includes a pressing device 610 and a winding device 620. The cut high-gloss PET film 700 is heated by the heating assembly 500 and then wound onto the winding device 620 after passing through the pressing device 610.
[0038] To clearly illustrate the previous embodiment, in one embodiment of this utility model, the pressing device 610 includes a connecting rod 611 and a pressing roller 612.
[0039] Two connecting rods 611 are respectively positioned vertically opposite each other between the two side plates 300, and two pressing rollers 612 are respectively rotatably mounted on the two connecting rods 611.
[0040] Among them, the high-gloss PET film 700, after being heated by the heating component 500, is squeezed by two pressure rollers 612.
[0041] To clearly illustrate the previous embodiment, in one embodiment of this utility model, the winding device 620 includes a second drive motor 621 and a winding roller 622.
[0042] The second drive motor 621 is mounted on the side plate 300, and the take-up roller 622 is connected to the output end of the second drive motor 621.
[0043] Specifically, when the relevant staff cut the high-gloss PET film 700, the staff first place the roll of high-gloss PET film 700 on the placement rack, pull out one end of the high-gloss PET film 700 and pass it between the cutting blade 414 and the support roller 420, and then pass through two heating plates 520. Then, the two sections of high-gloss PET film 700 cut out are respectively passed through two pressing devices 610 and then wound onto the corresponding winding device 620.
[0044] When the slitting assembly 400 is started, i.e., when the relevant personnel start the first drive motor 411, the first drive motor 411 drives the rotating shaft 413 to rotate through the transmission structure 412, and the cutting blade 414 rotates with the rotating shaft 413 and slits the high-gloss PET film 700.
[0045] After the cut edges of the high-gloss PET film 700 pass through the heating assembly 500, the relevant personnel control the control panel 540 to make the heating plate 520 heat the cut edges of the high-gloss PET film 700, so that the protruding burrs at the cut edges of the high-gloss PET film 700 melt.
[0046] After being heated, the high-gloss PET film 700 is pressed by two pressure rollers 612, which presses it against the edge of the high-gloss PET film 700, making the cut of the high-gloss PET film 700 smoother. Then it is wound up separately by the winding device 620.
[0047] In summary, the high-gloss PET film processing equipment according to the present invention heats the cut edge of the high-gloss PET film using a heating component, melting the protruding burrs, and then presses the melted burrs against the cut edge using a pressing device, ensuring a smooth cut and improving product quality.
