Description

Technical Field

[0001] The utility model relates to the technical field of film edge trimming, in particular to a polyester film edge trimming recovery device. Background Art

[0002] Polyester film, also known as PET film, is a packaging film with a wide range of properties. It offers excellent transparency and gloss, good airtightness and aroma retention, and moderate moisture resistance, though its moisture permeability decreases at low temperatures. PET film also possesses excellent mechanical properties, with the strongest toughness of all thermoplastics, and significantly higher tensile and impact strength than conventional films. It also offers good support and dimensional stability, making it suitable for secondary processing such as printing and paper bags. PET film also exhibits excellent heat and cold resistance, as well as good chemical and oil resistance. However, it is not resistant to strong alkalis and is susceptible to static electricity, for which no effective anti-static method exists. Therefore, care should be taken when packaging powdery items.

[0003] When polyester film is processed and formed, a trimming device is required to trim the polyester film, and the cut corner waste is collected and recycled. Most of the existing polyester film trimming and recycling devices are unable to adjust the position of the fixing device according to the size of the polyester film during the trimming process, so that polyester film of certain sizes cannot be fixed well when trimming, resulting in unsightly and uneven trimming. At the same time, when recycling the trimming waste, the trimmed material may be mistakenly moved to the waste collection box because the polyester film is not fixed.

[0004] Therefore, we propose a polyester film trimming recovery device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figures 1-4 As shown, the embodiment of the present invention provides a polyester film trimming recovery device, comprising:

[0024] The utility model discloses the tool of the present invention is fixedly connected to the edge trimming workbench 1, and two working frames are fixedly connected to the edge trimming workbench 1 at one end of the two working frames, and the working top plate is fixedly connected to the end of the working top plate away from the two working frames. The output end of the telescopic hydraulic press 2 passes through the working top plate, and the output end of the telescopic hydraulic press 2 is fixedly connected to the mounting connecting plate 3, so that the telescopic hydraulic press 2 can drive the mounting connecting plate 3 to rise and fall, and the mounting connecting plate 3 is fixedly connected to the end of the telescopic hydraulic press 2 away from the telescopic hydraulic press 2. A working cutting groove is provided on the edge trimming workbench 1, and the cutting knife 4 and the working cutting groove are installed in coordination, thereby ensuring that the polyester film can be trimmed smoothly and flatly; an adjustment component; the adjustment component includes a working slide 5 opened on the side wall of the edge trimming workbench 1, a working screw 6 is rotatably connected in the working slide 5, and one end of the working screw 6 passes through the edge trimming workbench 1 and is installed; a working handle is fixedly connected to the working screw 6, and the working handle is disc-shaped. The working handle and the working screw 6 are installed in coordination with each other, which makes it more convenient for the staff to rotate the working screw 6;

[0025] The working screw 6 is threadedly connected to a working slide block 7, and the working slide block 7 is slidably connected and installed with the inner wall of the working slide groove 5, thereby limiting the working slide block 7 so that the working slide block 7 can only slide along the direction of the working screw 6. The working slide block 7 is also provided with a downward pressing fixing assembly, which includes a working connecting plate 1 8 fixedly connected to the working slide block 7, and a working connecting plate 2 9 is connected to the side wall of the trimming workbench 1 away from the working slide block 7 through a guide assembly. The guide assembly includes a guide slot 13 opened on the trimming workbench 1, and a guide slider 14 is slidably connected in the guide slot 13. The other end of the guide slider 14 is fixedly connected to the working connecting plate 2 9, thereby ensuring that when the working screw 6 is rotated, the working connecting plate 2 9 can be driven to move together under the cooperation of the guide slot 13 and the guide slider 14;

[0026] Both the working connecting plate 1 8 and the working connecting plate 2 9 are provided with a lifting chute 10, and a lifting slider 11 is slidably connected in the two lifting chutes 10. The two lifting sliders 11 are jointly fixedly connected with a working pressure plate 12. The working pressure plate 12 and the trimming workbench 1 are installed in coordination with each other, so that the polyester film can be pressed and fixed, which is convenient for trimming and recycling waste. The working pressure plate 12 is made of rubber. A pulling handle is fixedly connected to the working pressure plate 12. The pulling handle and the working pressure plate 12 are installed in coordination with each other, which is convenient for the staff to pull the working pressure plate 12 upward. The end of the trimming workbench 1 close to the work frame is in the shape of a bevel. A waste collection box 15 is also fixedly connected to the trimming workbench 1, and the waste collection box 15 and the trimming workbench 1 cooperate with each other, which is convenient for the staff to quickly recycle the trimming waste into the waste collection box 15.

[0027] During the use of the present invention, the staff first places the polyester film raw material on the trimming workbench 1, and aligns the side to be cut with the working cutting groove and places it, and then rotates the working screw 6 according to the length of the polyester film. Due to the characteristics of the threaded connection, the working slider 7 will slide along the direction of the working screw 6 under the limiting action of the working slide groove 5, thereby making the working connecting plate 1 8 fixedly connected to the working slider 7 move together, thereby driving the working connecting plate 2 9 to move under the cooperation of the guide slide groove 13 and the guide slider 14, and then making the working pressure plate 12 move together. When the working pressure plate 12 moves to the polyester film, the staff presses the working pressure plate 12 downward to make it slide downward under the cooperation of the lifting slide groove 10 and the lifting slider 11, and press the polyester film tightly and fix it, and then start the telescopic hydraulic press 2 so that its output end drives the installation connecting plate 3 to move downward, thereby performing the edge trimming work on the polyester film through the trimming knife 4;

[0028] After the trimming is completed, the staff controls the telescopic hydraulic press 2 to drive the trimming knife 4 back to the initial position, and manually moves the waste generated by the trimming, collects it in the knife waste collection box 15, and then pulls the working pressure plate 12 upward to take out the polyester film with the trimmed edges.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
