[0042] The first connecting seat 431 is provided with a first rotating shaft 433 rotatably connected with the third driving mechanism 42, one end of the first rotating shaft 433 is rotatably connected with a bearing with a seat 434 arranged on the first connecting seat 431, the other end of the first rotating shaft 433 is connected with the first connecting plate 422 installed on the first linear sliding table 421, the first connecting plate 422 can also be provided with a bearing matched with the first rotating shaft 433, and the working bottom plate 8 is further provided with an angle adjusting plate 44 matched with the third driving mechanism 42, the angle adjusting plate 44 is provided with an arc-shaped adjusting groove 441 matched with the third driving mechanism 42, the center of the arc-shaped adjusting groove 441 is on the axis of the first rotating shaft 433, and corresponding connecting members such as screws lock the third driving mechanism 42 and the angle adjusting plate 44 through the arc-shaped adjusting groove 441. When it is necessary to adjust the inclination angle of the material clamping mechanism 41, the third driving mechanism 42 is swung up and down about the first rotating shaft 433 to a suitable angle, and then the third driving mechanism 42 and the angle adjusting plate 44 are locked through the arc-shaped adjusting groove 441 by using connecting members such as screws, so that the material clamping mechanism 41 can be adjusted to a suitable angle position, so that the material clamping mechanism 41 can better clamp the material belt, and the stability and reliability are higher.

[0043] The bottom of the working base plate 8 is equipped with adjustable feet 81, typically located at each of the four corners of the bottom. These adjustable feet facilitate leveling of the entire device, making operation convenient and improving the stability and reliability of the equipment. A protective cover 7, corresponding to the shearing device 5, can also be installed on the working base plate 8. The protective cover 7 is located between the air-cooling assembly 3 and the material-pulling device 4. The protective cover 7 can be made of metal or plastic such as acrylic, providing better protection and enhancing safety and reliability.

[0044] During use, the clamping mechanism 41 of the feeding device 4 clamps the end of the strip, and the third drive mechanism 42 drives the clamping mechanism 41 to move, thereby pulling the strip forward through the first channel 101 of the feeding component 1, the heating and forming mold 22 of the heating and forming device 2, and the second channel 301 of the air cooling component 3. The heating and forming mold 22 of the heating and forming device 2 continuously heats and forms the corresponding products on the strip. The air cooling component 3 blows air to cool the formed strip. The distance of each feeding is usually the length of one product or a group of products. Then, the second drive mechanism 54 of the shearing device 5 drives the first drive mechanism 53 and the scissors 52 to move as a whole to the appropriate cutting position of the strip. The first drive mechanism 53 of the shearing device 5 then drives the scissors 52 to cut the strip.

Moreover, the first channel 101 of the feeding component 1 can ensure that the material strip enters the heating and forming device 2 stably. The formed material strip passes through the second channel 301 of the air cooling component 3. The corresponding external air supply device blows air to cool the formed material strip through the air hole 302 above the second channel 301. In this way, it is not easy to cause product misalignment and breakage, material waste, product contamination, etc. during the material pulling and forming process. The height adjustment component 43 and the angle adjustment plate 44 can also adjust the overall height and tilt angle of the clamping mechanism 41 and the third drive mechanism 42, which makes it easier to adjust the clamping mechanism 41 to a suitable position to better clamp the material strip. The stability and reliability are higher, thereby improving the overall quality and yield of the product.
