[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model allows for the ironing of laid PE fabric via the bottom of the ironing box. Through ironing preheating, the fibers in the PE fabric will shrink and stabilize to a certain extent, which helps to reduce dimensional changes after cutting and improve cutting accuracy. Furthermore, ironing can eliminate wrinkles and uneven parts in the fabric, making the fabric surface smoother.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figure 1 , Figure 3 and Figure 4 A PE fabric cutting device includes a cutting platform 1, a support frame 2 fixedly installed at the middle position of the top surface of the cutting platform 1, an electric cylinder 3 fixedly installed at the middle position of the support frame 2, and a carrier frame 4 fixedly installed at the telescopic end of the electric cylinder 3; a pre-treatment component 5 is provided at the rear end of the carrier frame 4, the pre-treatment component 5 includes a carrier ironing box 502 fixedly installed at the rear end of the carrier frame 4, a hot steam pipe 501 passing through the upper end of the carrier ironing box 502, a high-temperature steam chamber 503 is opened inside the carrier ironing box 502, and a plurality of penetration holes 504 are opened at the bottom end surface of the carrier ironing box 502, and the penetration holes 504 are interconnected with the high-temperature steam chamber 503. Two symmetrically distributed pressure supports 7 are fixedly installed at the bottom front side of the support frame 4. The bottom surface of the pressure support 7 is on the same plane as the bottom surface of the ironing box 502. Support rods 11 are fixedly installed on both sides of the front end of the cutting platform 1. A pressing rod 9 is movably installed on the inner side of the support rod 11. The pressing rod 9 can press the PE fabric laid on the cutting platform 1, which can prevent the PE fabric laid on the cutting platform 1 from detaching from the cutting platform 1 excessively. A take-up roller 10 is also rotatably installed on the inner side of the support rod 11. The take-up roller 10 is detachably connected to the support rod 11. The take-up roller 10 can be replaced after the take-up is completed by disassembly.

[0029] By adopting the above technical solution, in use, the PE fabric to be cut is laid on the cutting platform 1, and the fabric is passed through the support frame 2, attached to the pressure rod 9, and wrapped around the take-up roller 10 of the support rod 11. The rotation of the take-up roller 10 can take up the fabric to be cut. The electric cylinder 3 is activated, and the operation of the electric cylinder 3 can push the support frame 4 to move up and down. The support frame 4 can drive the pressure tray 7 to move up and down, and the pressure tray 7 can press the laid fabric. At the same time, the ironing box 502 will move up and down with the support frame 4. The upper end of the ironing box 502 is connected to the hot steam pipe 501, and the high-temperature steam chamber 503 can supply steam to the ironing box 502. A large amount of hot steam is injected into the high-temperature steam chamber 503 of component 2. The heat transfer of the hot air in the high-temperature steam chamber 503 can heat up the ironing box 502, so that the bottom of the ironing box 502 can iron the laid PE fabric. Through the ironing preheating treatment, the fibers in the PE fabric will shrink and stabilize to a certain extent, which helps to reduce the dimensional changes after cutting and improve the cutting accuracy. In addition, ironing can eliminate wrinkles and uneven parts in the fabric, making the fabric surface smoother. In this way, during the cutting process, the cutter can cut more accurately along the predetermined lines, reducing the cutting error caused by uneven fabric.

[0030] Specifically, such as Figures 1 to 4 As shown, a cutting component 6 is fixedly installed at the middle position of the bottom end face of the cutting platform 1. The cutting component 6 includes a speed-regulating motor 601 fixedly installed at the middle position of the bottom end face of the cutting platform 1. A cutting circular blade 602 is fixedly installed at the output end of the speed-regulating motor 601. The cutting circular blade 602 is located between two pressure supports 7. A cutting groove 603 is provided above the cutting circular blade 602 and is opened inside the cutting platform 1. A cleaning component 8 is provided at the rear bottom end of the support frame 4. The cleaning component 8 includes two symmetrically distributed brackets 801 fixedly installed at the rear bottom end of the support frame 4. A cleaning brush roller 802 is rotatably installed on the inner side of the brackets 801. The lowest point of the outer periphery of the cleaning brush roller 802 is lower than the bottom end face of the ironing box 502.

[0031] By adopting the above technical solution, when in use, the speed-regulating motor 601 is started, which drives the cutting circular blade 602 to rotate. The cutting circular blade 602 can contact the PE fabric through the cutting groove 603, thereby cutting the PE fabric. At the same time, the support frame 4 can drive the cleaning component 8 to move up and down. Before the ironing box 502 is used for ironing, the cleaning brush roller 802 in front of the ironing box 502 can rotate and clean the laid fabric. The friction generated by the contact and rotation of the cleaning brush roller 802 with the PE fabric effectively removes dust, impurities and other dirt from the surface of the PE fabric. This physical cleaning method is fast and direct, and can significantly improve the cleanliness of the fabric in a short time. At the same time, the high-temperature steam inside the high-temperature steam chamber 503 can condense into liquid water droplets. The water droplets can seep into the end face of the PE fabric through the permeation hole 504, thus providing suitable humidity around the PE fabric. With the increase of humidity, water molecules in the air can more effectively combine with charged particles, promoting charge neutralization. This neutralization effect helps reduce the accumulation and discharge of static electricity, thus effectively neutralizing the static electricity generated when the cleaning brush roller 802 rubs against the fabric, the static electricity generated when the pressure support 7 squeezes the fabric, and the static electricity generated during cutting, thereby reducing the impact of static electricity accumulation during cutting.

[0032] Working principle: In use, the PE fabric to be cut is laid on the cutting platform 1, and the fabric is passed through the support frame 2, adhered to the pressure rod 9, and wound around the take-up roller 10 of the support rod 11. The rotation of the take-up roller 10 can take up the fabric to be cut. The electric cylinder 3 is activated, which pushes the support frame 4 to move up and down. The support frame 4 can drive the pressure tray 7 to move up and down, and the pressure tray 7 can press the laid fabric. At the same time, the ironing box 502 will move up and down with the support frame 4. The upper end of the ironing box 502 is connected to the hot steam pipe 501. A large amount of hot steam can be injected into the high-temperature steam chamber 503 of the ironing box 502 through the high-temperature steam chamber 503. Through the heat transfer of the hot air in the high-temperature steam chamber 503, the ironing box 502 can be ironed. The heat generated allows the bottom of the ironing box 502 to iron the laid PE fabric. Activating the speed-regulating motor 601 drives the cutting blade 602 to rotate. The cutting blade 602 contacts the PE fabric through the cutting groove 603, cutting the fabric. Simultaneously, the support frame 4 moves the cleaning component 8 up and down. Before ironing, the cleaning brush roller 802 in front of the ironing box 502 rotates and cleans the fabric. The friction generated by the rotating cleaning brush roller 802 effectively removes dust, impurities, and other dirt from the PE fabric surface. This physical cleaning method is fast and direct, significantly improving the cleanliness of the fabric in a short time. Meanwhile, the high-temperature steam inside the high-temperature steam chamber 503 condenses into small water droplets, which seep into the end face of the PE fabric through the permeation holes 504, thus providing suitable humidity around the PE fabric.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
