Description

Technical Field

[0001] The present application relates to the technical field of high-barrier plastic packaging bag processing, and specifically to a die-cutting device for high-barrier plastic packaging bag processing. Background Art

[0002] High-barrier plastic packaging bags are made of special materials and technologies, with excellent barrier properties. Through the combination of different materials, they can block a variety of substances such as oxygen, water vapor, fragrance, grease, etc.; at the same time, the multi-layer structure also gives the packaging bags good physical properties such as compression resistance, drop resistance, and tensile resistance, ensuring the stability and safety of the packaging bags during transportation, storage and use. They are widely used in food, medicine, chemical and other fields.

[0003] High-barrier plastic packaging bags require die-cutting knives to produce specific shapes and sizes. During cutting, the high-barrier plastic packaging bags need to be straightened to spread out their surfaces, so as to ensure the size during cutting. However, existing die-cutting devices simply straighten the plastic film of the packaging bag during cutting. During cutting, the plastic film will shrink toward the center due to the tension, resulting in wrinkles, which affects the cutting effect. Utility Model Content

[0004] The purpose of this application is to provide a die-cutting device for processing high-barrier plastic packaging bags, which solves the problem in the background technology that the existing die-cutting device simply straightens the plastic film of the packaging bag during cutting. During cutting, the plastic film will shrink toward the center due to the tension, thereby generating wrinkles and affecting the cutting effect.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a die-cutting device for processing high-barrier plastic packaging bags, comprising a base, an adjustment slot, a mounting bracket, a rotating rod and a fixed wheel, wherein the left and right sides of the center of the top of the base are fixedly connected with an adjustment slot, the inner side of the adjustment slot is rotatably connected with a bidirectional screw rod, the surface of the bidirectional screw rod is threadedly connected with threaded blocks on both sides, the top of the threaded block is fixedly connected with a vertical rod, and the surface of the vertical rod facing the center of the base is fixedly connected with two upper and lower parallel mounting brackets, the two ends of the rotating rod are respectively rotatably connected to the left and right inner wall surfaces of the mounting bracket, and the surface of the rotating rod is fixedly connected with several fixed wheels.

[0006] In this technical solution, the two side edges of the plastic film pass through between the upper and lower mounting frames, and the fixed wheel contacts the upper and lower surfaces of the plastic film. At this time, after the No. 2 motor is started, it will drive the rotating dry fixed wheel to rotate. During the rotation process, the fixed wheel will push the surface of the plastic film outward, so that the surface of the plastic film remains straight, reducing the generation of wrinkles, ensuring the die-cutting effect, and improving the die-cutting efficiency of the device; when different plastic films are pushed, the No. 2 motor starts and drives the double screw to rotate, so that the surface thread block and the vertical rod move relative to each other, thereby changing the distance between the mounting frames on both sides, thereby adapting to plastic films of different widths and improving the practicality of the device.

[0007] As an optional solution to the technical solution of the present application, the outer surface of one end of the adjustment slot of the horizontal position of the bidirectional screw is fixedly connected to motor No. 1, and the outer end of the transmission shaft of motor No. 1 is fixedly connected to one end of the bidirectional screw.

[0008] As an optional solution of the technical solution of the present application, a No. 2 motor is fixedly connected to the outer wall of the mounting frame at the horizontal position of the rotating rod, and the outer end of the transmission shaft of the No. 2 motor is fixedly connected to one end of the rotating rod.

[0009] As an optional solution of the technical solution of the present application, a support frame is fixedly connected to the center of the side wall of the base, an electric push rod is fixedly connected to the lower surface of the top of the support frame, the bottom of the electric push rod is fixedly connected to the base plate, and the bottom of the base plate is fixedly connected to a die-cutting knife.

[0010] As an optional solution of the technical solution of the present application, support plates are fixedly connected to the front and rear edges of both sides of the top of the base, and two groups of upper and lower parallel transmission rollers are rotatably connected between the support plates.

[0011] As an optional solution of the technical solution of the present application, a die-cutting table is fixedly connected to the center of the top of the base, and the die-cutting table is located directly below the die-cutting knife.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This application can move both sides of the plastic film through the mounting frame, the rotating rod and the fixed wheel. The two side edges of the plastic film pass through the upper and lower mounting frames, and the fixed wheel contacts the upper and lower surfaces of the plastic film. At this time, after the No. 2 motor is started, it will drive the rotating and fixed wheel to rotate. During the rotation process, the fixed wheel will move the surface of the plastic film outward, so that the surface of the plastic film remains straight, reducing the generation of wrinkles, ensuring the die-cutting effect, and improving the die-cutting efficiency of the device.

[0014] 2. This application can adjust the distance between the mounting brackets on both sides through the adjustment slot, bidirectional screw rod, threaded block and vertical rod. When different plastic films are moved, the No. 2 motor starts to drive the double screw rod to rotate, causing the threaded block and the vertical rod on the surface to move relative to each other, thereby changing the distance between the mounting brackets on both sides, thereby adapting to plastic films of different widths and improving the practicality of the device.

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0020] A die-cutting device for processing high-barrier plastic packaging bags, see Figures 1 to 2 , including a base 1, an adjusting slot 8, a mounting bracket 12, a rotating rod 13 and a fixed wheel 14. The left and right sides of the top center of the base 1 are fixedly connected with the adjusting slot 8, the inner side of the adjusting slot 8 is rotatably connected with a bidirectional screw rod 9, and both sides of the surface of the bidirectional screw rod 9 are threadedly connected with threaded blocks 10. The top of the threaded block 10 is fixedly connected with a vertical rod 11, and the surface of the vertical rod 11 facing the center of the base 1 is fixedly connected with two upper and lower parallel mounting brackets 12. The two ends of the rotating rod 13 are respectively rotatably connected to the left and right inner wall surfaces of the mounting bracket 12, and the surface of the rotating rod 13 is fixedly connected with several fixed wheels 14.

[0021] Specifically, such as Figure 1As shown, the outer surface of one end of the adjustment slot 8 in the horizontal position of the bidirectional screw rod 9 is fixedly connected to the No. 1 motor 901, and the outer end of the transmission shaft of the No. 1 motor 901 is fixedly connected to one end of the bidirectional screw rod 9. After the No. 1 motor 901 is started, it drives the rotating rod 13 to rotate, so that the fixed wheel 14 can move the plastic film, and the motor speed can be controlled to handle wrinkles of different degrees, which is very practical.

[0022] It is worth noting that if Figure 2 As shown, the outer wall of the mounting frame 12 in the horizontal position of the rotating rod 13 is fixedly connected to the No. 2 motor 15, and the outer end of the transmission shaft of the No. 2 motor 15 is fixedly connected to one end of the rotating rod 13. After the No. 2 motor 15 is started, it will drive the bidirectional screw 9 to rotate, so that the threaded block 10 moves with the upper mounting frame 12, thereby adjusting the spacing to adapt to plastic films of different widths.

[0023] It is worth noting that if Figure 1 and Figure 2 As shown, a support frame 5 is fixedly connected to the center of the side wall of the base 1, an electric push rod 6 is fixedly connected to the lower surface of the top of the support frame 5, the bottom of the electric push rod 6 is fixedly connected to the bottom of the base plate 7, and the bottom of the base plate 7 is fixedly connected to a die-cutting knife 701. The shape of the die-cutting knife 701 is set according to actual needs, so as to cut plastic films of different shapes and sizes.

[0024] It is worth noting that if Figure 1 As shown, support plates 2 are fixedly connected to the front and rear edges of both sides of the top of the base 1, and two sets of upper and lower parallel transmission rollers 3 are rotatably connected between the support plates 2. After the transmission rollers 3 rotate, they will drive the plastic film to move, thereby completing automatic loading, and the transmission rollers 3 are driven by corresponding motors. The technology is very mature, so it will not be described in detail.

[0025] It is worth noting that if Figure 1 As shown, a die-cutting table 4 is fixedly connected to the center of the top of the base 1. The die-cutting table 4 is located directly below the die-cutting knife 701. The die-cutting table 4 mainly provides support from below during the die-cutting process, and its height is located between the upper and lower sets of fixed wheels 14, so that the plastic film has no undulations, reduces pulling, and avoids large wrinkles during the die-cutting process.

[0026] It should be noted that the die-cutting means and corresponding equipment are relatively mature in the market. The die-cutting mechanism in this application does not make any structural and functional improvements to it, so it will not be described in detail.

[0027] In actual use, the plastic film for producing high-barrier plastic packaging bags moves between the upper and lower transmission rollers 3. When passing through the die-cutting table 4, the die-cutting knife 701 will be driven down by the powered push rod 6 to die-cut the plastic film. In this process, the two side edges of the plastic film pass between the upper and lower mounting frames 12, and the fixed wheel 14 contacts the upper and lower surfaces of the plastic film. At this time, after the No. 2 motor 15 is started, it will drive the rotating and drying fixed wheel 14 to rotate. During the rotation, the fixed wheel 14 will push the surface of the plastic film outward, so that the surface of the plastic film remains straight, reducing the generation of wrinkles, ensuring the die-cutting effect, and improving the die-cutting efficiency of the device; when moving different plastic films, the No. 2 motor 15 starts and drives the double screw to rotate, so that the surface thread block 10 and the vertical rod 11 move relative to each other, thereby changing the spacing between the mounting frames 12 on both sides, thereby adapting to plastic films of different widths and improving the practicality of the device.
