[0002] At present, the development of my country's packaging bag industry has entered a mature stage, shifting from quantitative expansion and rapid development to optimized structure and steady improvement. As an important member of the packaging field, bag making machines play a vital role in the food, medicine, chemical and other industries. Their high efficiency and stability have become important indicators for measuring their performance. Improving the cutting process in the bag making process is of great significance to ensuring the high efficiency and stability of the work. When cutting hard chemical bags, most cutting equipment on the market adopts a "guillotine-type" cutting method, which has a relatively backward structure, high failure rate and low efficiency. Therefore, how to provide a high-efficiency cutting mechanism and improve the stability of the equipment is particularly important. Utility Model Content

[0003] The purpose of the utility model is to provide a packaging bag cutting mechanism to improve the packaging bag cutting efficiency and stability.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a packaging bag cutting mechanism comprising a conveyor platform, a first support frame fixedly connected to the rear of the conveyor platform, a conveyor roller connected to the first support frame via a rotating shaft, a second support frame fixedly connected to the front of the conveyor platform, a motorized push rod fixedly connected to the top of the second support frame, a hot cutter fixedly connected to the lower end of the motorized push rod, and a bag stacking basket provided at the front of the conveyor platform. When the device is activated, the conveyor roller delivers the packaging bag under the hot cutter, the motorized push rod drives the hot cutter downward to complete the cutting, and the cut packaging bag falls into the bag stacking basket for sequential stacking.

[0005] Preferably, two exhaust gas absorption pipes are fixedly connected to the inner side of the second support frame, and the two exhaust gas absorption pipes are respectively located on the front and rear sides of the hot cutter and have drainage holes at the bottom.

[0006] Preferably, an oil-soaked sponge strip is fixedly connected to the inner side of the second support frame, and a gap is left in the middle of the oil-soaked sponge strip. When the electric push rod is activated, the hot cutter moves up and down, passing through the gap in the oil-soaked sponge strip, and generates contact friction. The surface of the hot cutter is cleaned and a layer of oil film is attached to the surface of the blade. The oil film can prevent the hot cutter from sticking to the packaging bag during cutting.

[0007] Preferably, the hot cutter adopts an inclined blade. The design of the inclined blade improves the cutting effect and improves the quality of the cut part.

[0008] Preferably, the bag stacking basket includes a support platform, with baffles fixedly connected to the rear and right sides of the support platform, a first movable baffle connected to the left side of the support platform via a slide rail, and a second movable baffle connected to the front of the support platform via a slide rail, so that the size of the bag stacking basket can be adjusted according to packaging bags of different sizes.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The utility model adopts the cutter structure, and with the cooperation of the support frame, the electric push rod and the hot cutter, it can reduce the movement stroke of the cutter while maintaining the original cutting strength, thereby improving the cutting efficiency and the quality of the cutting part, reducing the failure rate of the equipment, and at the same time improving the bag stacking and collecting device, which can be adjusted according to the size of packaging bags of different sizes, and the neatness of the stacking of packaging bags is regularized, which reduces the time of workers in sorting and improves work efficiency.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3A packaging bag cutting mechanism includes a conveyor platform 1, a first support frame 8 fixedly connected to the rear of the conveyor platform 1, which is connected to a conveyor roller 7 via a rotating shaft. The front end of the conveyor platform 1 is fixedly connected to a second support frame 2, the top of the second support frame 2 is fixedly connected to an electric push rod 3, and the lower end of the electric push rod 3 is fixedly connected to a hot cutter 4. A bag stacking basket 9 is provided at the front of the conveyor platform 1. When the device is started, the conveyor roller 7 feeds the packaging bag under the hot cutter 4, and the electric push rod 3 drives the hot cutter 4 downward to complete the cutting. The cut packaging bags fall into the bag stacking basket 9 and are stacked in sequence.

[0018] Two exhaust gas absorption pipes 5 are fixedly connected to the inner side of the second support frame 2. The two exhaust gas absorption pipes 5 are respectively located on the front and rear sides of the hot cutter 4 and have drainage holes at the bottom. When the exhaust gas absorption device is started, the exhaust gas is sucked into the exhaust gas absorption device through the drainage holes for collection and purification.

[0019] An oil-soaked sponge strip 6 is fixedly connected to the inner side of the second support frame 2, with a gap in the middle of the oil-soaked sponge strip 6. When the electric push rod 3 is activated, the hot cutter 4 moves up and down, passing through the gap in the oil-soaked sponge strip 6, generating contact friction. The surface of the hot cutter 4 is cleaned and a layer of oil film is attached to the surface of the blade, which prevents the hot cutter from sticking to the packaging bag during cutting.

[0020] The hot cutting knife 4 has an inclined blade, which improves the cutting effect and the quality of the cut part.

[0021] The bag stacking basket 9 includes a support platform 903, with baffles fixedly connected to the rear and right sides of the support platform 903. A first movable baffle 901 is connected to the left side of the support platform 903 via a slide rail 906, and a second movable baffle 902 is connected to the front of the support platform 903 via a slide rail 907. This allows the bag stacking basket 9 to be adjusted in size according to packaging bags of different sizes, ensuring neat stacking of the bags.

[0022] During use, first pass the packaging bag through the bottom of the conveying roller 7 and align it with the hot cutter 4. The bag stacking basket 9 moves the first movable baffle 901 and the second movable baffle 902 according to the size of the packaging bag to limit the position, start the controller 10, and the conveying roller 7 drives the packaging bag to move forward. The packaging bag moves to the specified size, and the electric push rod 3 drives the hot cutter 4 to move downward to cut the packaging bag from left to right. The hot cutter 4 constantly contacts and rubs with the oil-soaked sponge strip 6 during the up and down movement to clean the residue on the surface of the hot cutter 4. The exhaust gas generated during the hot cutting process is sucked away by the exhaust gas absorption pipe 5. The cut packaging bag falls into the bag stacking basket 9 to complete the cutting process.

[0023] In summary, the packaging bag cutting mechanism, through the coordinated use of the conveying pressure roller 7, the hot cutting knife 4, the exhaust gas absorption tube 5, the electric push rod 3, and the bag stacking basket 9, solves the problem in the market that when cutting chemical bags with relatively hard texture, most of them adopt the "guillotine-type" cutting method, which has a relatively backward structure, a high failure rate, and low efficiency. At the same time, it improves the packaging bag stacking device and reduces the problem of uneven stacking of packaging bags.
