Detailed implementation manners

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0020] Please refer to Figures 1 - 3 , a plastic packaging bag cutting device, including a workbench 1.

[0021] In the specific implementation process, as Figure 1 , Figure 2 and Figure 3 shown, a cleaning component 2 is provided at the bottom of the workbench 1, a lifting plate 3 is provided above the workbench 1, a pressing component 4 is provided outside the lifting plate 3, a cutting knife 5 is provided at the bottom of the lifting plate 3, a collection box 6 is provided at the bottom of the workbench 1, baffles 7 are fixedly connected to both sides of the top of the workbench 1, a fixing frame 8 is fixedly connected to the top of the workbench 1, an electric push rod 9 is provided at the top of the fixing frame 8, and the top rod of the electric push rod 9 is fixedly connected to the top of the lifting plate 3. The cleaning component 2 includes a cutting groove 21 provided at the top of the workbench 1, a discharge groove 22 is opened at the top of the collection box 6, a first spring 23 is fixedly connected to the inner wall of the collection box 6, the number of the first springs 23 is set to two, one end of the first spring 23 is fixedly connected to a moving plate 24, a scraping plate 25 is fixedly connected to one side of the moving plate 24, a collection cabinet 26 is slidably arranged inside the collection box 6, the cutting groove 21 is communicated with the discharge groove 22, and one side of the scraping plate 25 is attached to one side of the cutting knife 5.

[0022] The pressing component 4 includes connecting blocks 41 provided on both sides of the lifting plate 3, a connecting seat 42 is slidably arranged outside the connecting block 41, a second spring 43 is arranged inside the connecting seat 42, and a pressing plate 44 is fixedly connected to the bottom of the connecting seat 42.

[0023] It should be noted that: Stack the packaging bags neatly and pass them under the cutter 5 and place them on the top of the workbench 1. The part to be cut corresponds to the position under the cutter 5. The electric push rod 9 at the top of the fixing frame 8 drives the lifting plate 3 to move downward. The lifting plate 3 drives the cutter 5 to move downward to cut the packaging bag. While the lifting plate 3 moves downward, the connecting blocks 41 on both sides thereof drive the connecting seat 42 and the pressing plate 44 to move downward. Under the elastic force of the second spring 43, the bottom of the pressing plate 44 is closely attached to the top of the packaging bag, so as to press and fix the packaging bag at both sides of the cutter 5, making the packaging bag not prone to deviation during cutting. When the cutter 5 cuts the packaging bag, it enters the cutting groove 21 and the discharge groove 22 to cut off the packaging bag. When the cutter 5 enters the discharge groove 22, the scraping plate 25 fits with the two side surfaces of the cutter 5 under the elastic force of the moving plate 24 and the first spring 23 to scrape the debris on the cutter 5 once. When the cutter 5 moves upward, the scraping plate 25 still fits with the two side surfaces of the cutter 5 under the elastic force of the moving plate 24 and the first spring 23 to scrape the debris on the cutter 5 a second time, making the cutter 5 cleaner without residual debris. The debris scraped off for the first time falls into the cutting groove 21 and is discharged into the collection cabinet 26 in the collection box 6 through the discharge groove 22. The debris scraped off for the second time will directly be discharged into the collection cabinet 26 through the discharge groove 22 to collect the scraped debris, thus achieving the effect of not only cleaning and collecting the residual debris on the cutter 5, but also improving the stability and flatness of the packaging bag during cutting and improving the product quality.

[0024] Limit slots 10 are provided on both sides of the fixing frame 8, and limit blocks 11 are slidably connected in the limit slots 10. One side of the limit block 11 is fixedly connected to one side of the lifting plate 3.

[0025] Sliders 12 are fixedly connected to both sides of the pressing plate 44, and the outer sides of the sliders 12 are slidably matched with the inner wall of the baffle 7.

[0026] A handle 13 is fixedly connected to one side of the collection cabinet 26, and fixing legs 14 are fixedly connected to the four corners of the bottom of the workbench 1.

[0027] A reinforcing rod 15 is fixedly connected to one side of the fixing leg 14, and a moving wheel 16 is fixedly connected to the bottom of the fixing leg 14.

[0028] It should be noted that during the lifting process of the lifting plate 3, the limit blocks 11 on both sides thereof slide in the limit grooves 10 opened on both sides of the fixed frame 8 to guide and limit the lifting plate 3, improving the stability of the lifting plate 3 during the lifting process. When the pressing plate 44 moves up and down, the sliders 12 on both sides thereof slide on the inner wall of the baffle 7 to guide and limit both sides of the pressing plate 44, keeping the pressing plate 44 horizontal during lifting and improving the pressing effect on the packaging bag. The collection cabinet 26 can be conveniently pushed and pulled through the handle 13. The workbench 1 is supported and fixed by the fixed legs 14 and the reinforcing rods 15, improving the stability of the workbench 1. The device can be conveniently moved through the moving wheels 16.

[0029] The working principle of a plastic packaging bag cutting device provided by the present utility model is as follows:

[0030] During use, the plastic packaging bag is laid flat and passed under the cutter 5 and under the pressing plate 44 and placed on the top of the workbench 1. The part to be cut corresponds to the position under the cutter 5. The electric push rod 9 at the top of the fixed frame 8 drives the lifting plate 3 to move downward, and the lifting plate 3 drives the cutter 5 to move downward to cut the packaging bag. While the lifting plate 3 moves downward, the connecting blocks 41 on both sides thereof drive the connecting seats 42 and the pressing plate 44 to move downward. Under the elastic force of the second spring 43, the bottom of the pressing plate 44 closely adheres to the top of the packaging bag, thereby pressing and fixing the packaging bag on both sides of the cutter 5, making the packaging bag not prone to deviation during cutting. When the cutter 5 cuts the packaging bag, it enters the cutting groove 21 and the discharge groove 22 to cut off the packaging bag. When the cutter 5 enters the discharge groove 22, the scraping plate 25 fits with the two side surfaces of the cutter 5 under the elastic force of the moving plate 24 and the first spring 23 to scrape the debris on the cutter 5 once. When the cutter 5 moves upward, the scraping plate 25 still fits with the two side surfaces of the cutter 5 under the elastic force of the moving plate 24 and the first spring 23 to scrape the debris on the cutter 5 a second time, making the cutter 5 cleaner without residual debris. The debris scraped off for the first time falls into the cutting groove 21 and is discharged into the collection cabinet 26 in the collection box 6 through the discharge groove 22. The debris scraped off for the second time will directly be discharged into the collection cabinet 26 through the discharge groove 22 to collect the scraped debris, thus achieving the effect of not only cleaning and collecting the residual debris on the cutter 5, but also improving the stability and flatness of the packaging bag during cutting and improving the product quality.

[0031] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
