Description

Technical Field

[0001] This invention relates to the field of oven technology, specifically to a structure for an oven specifically designed for stretch film. Background Technology

[0002] The transverse stretching machine uses a two-sided fan-blowing structure in each zone, consisting of a fan support, two fans, and eight to twelve static pressure boxes. Baffles are added between zones. The static pressure boxes change the direction and speed of the airflow. The fans on both sides of the oven blow air in opposite directions to achieve a pressure equalization effect. However, the existing oven structure cannot fully mix hot and cold air, and cannot guarantee uniform airflow and temperature, resulting in uneven thickness of the finished film and affecting the quality of the finished product.

[0003] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a special oven structure for stretch film. Summary of the Invention

[0004] The purpose of this invention is to provide a special oven structure for stretch film to solve the common problems mentioned in the background art.

However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example

[0021] Please see Figure 1-2As shown, the present invention provides a structural technical solution for a special drying oven for stretch film: including a base 11, a base frame 12 is provided on the base 11, and an oven assembly is provided on the base frame 12. The oven assembly includes a plurality of fan chambers 22, and heaters 24 are provided on both sides of the plurality of fan chambers 22. A filter 25 is provided on the outside of the heaters 24, and the filter 25 is connected to the fan chambers 22.

[0022] One of the fan rooms 22 is adjacent to a fan room 21. Both fan rooms 21 are equipped with coolers 23 on both sides, and filters 25 are installed on the outside of the coolers 23. The filters 25 are connected to the fan room 21.

[0023] Both fan room 1 21 and fan room 22 are equipped with a base 26 on their back sides. A fan 27 is installed on the base 26 and is connected to it. Both fan room 1 21 and fan room 22 are equipped with air ducts 28 on their end faces. Several air holes 282 are provided on the air ducts 28.

[0024] In this embodiment, the heater 24 and the fan 27 are started. The fan 27 draws in the outside air and the hot air on the surface of the heater 24. The hot air is then discharged through the air duct 28 and blown out evenly through the air holes 282. The multiple air holes 282 can ensure that the hot air flows evenly, forming a uniform temperature field and pressure field, so that the stretch film deforms evenly and improves the thickness uniformity of the stretch film.

[0025] After stretching, the cooler 23 is activated to generate cooling. The fan 27 draws in outside air, along with the cold air, which is then discharged through the air hole 282 on the air duct 28, thus cooling the membrane.

[0026] Please see Figure 1-2 As shown, several fan rooms 1 21 and fan room 22 are arranged in a relative manner, and the air ducts 28 on the several fan rooms 1 21 and fan room 22 are arranged in a staggered manner.

[0027] In this embodiment, the staggered air ducts 28 can uniformly discharge air, forming a uniform temperature field and pressure field, which causes the stretch film to deform uniformly and improves the thickness uniformity of the stretch film.

[0028] Please see Figure 1-2 As shown, a damper 281 is installed between the fan room 1 21, the fan room 22 and the air duct 28. A sealing ring is installed between the damper 281 and the interface of the air duct 28, the fan room 1 21 and the fan room 22, and they are fastened together by bolts.

[0029] In this embodiment, the use of sealing rings can improve the sealing effect between interfaces.

[0030] Please see Figure 1-2As shown, the air ducts 28 on the fan room 1 21 and the fan room 22 are arranged symmetrically along the vertical plane, and a partition plate 13 is provided between the air ducts 28. Several air holes 282 on the outer wall of the air ducts 28 are arranged in a staggered manner.

[0031] In this embodiment, the multiple air holes 282 can exert uniform force on the membrane surface, thereby achieving uniform deformation.

[0032] Please see Figure 1-2 As shown, a number of air ducts 28 are provided with fixed pipe supports 31 at their top, and a number of clamping blocks 32 are provided on the fixed pipe supports 31, which are pressed against the air ducts 28.

[0033] In this embodiment, the fixed pipe bracket 31 and the clamping block 32 can be used to assemble and position the air duct 28, thereby improving its stability.

[0034] Please see Figure 1-2 As shown, both the bottom of fan room 1 21 and fan room 22 are provided with several support seats 211.

[0035] In this embodiment, the support base 211 can provide stable support for the fan room 1 21 and the fan room 22.

[0036] The working principle and usage process of this invention: After the invention is installed, it is operated according to the above implementation method until all working steps are completed.
