Description

Technical Field

[0001] This utility model belongs to the field of membrane material production and processing technology, and specifically relates to a device for improving the uniformity of membrane material heating temperature. Background Technology

[0002] During the production of membrane materials, different types of films are bonded together to form a composite film according to different usage requirements. When processing membrane materials for composite, a composite device with a heating mechanism is generally required. The film is heated and then pressure is applied to the film so that the films can be bonded together to form a composite film.

[0003] For example, Chinese Patent Publication No. CN 219947321 U discloses a composite heating device for EPE and PET film materials, which includes a base, a fixed frame and a control cabinet disposed on the upper surface of the base, two material rolls, and a composite roller. The inner side of the fixed frame is provided with two fixed plates, and the same side surface of the two fixed plates is provided with a U-shaped frame through a first adjustment mechanism. The two fixed plates are connected by a connecting frame. The fixed frame and the U-shaped frame are connected by a second adjustment mechanism. The outer side of the fixed frame is provided with a box with openings at both ends. The inside of the box is provided with an adjustment frame through a double-headed screw. The outer side of the adjustment frame is provided with an installation rod. The control cabinet is located on the side of the fixed frame away from the box. The device controls the motor of the first adjustment mechanism and the electric telescopic rod of the second adjustment mechanism through the control cabinet to quickly realize the correction of EPE and PET and the tension adjustment of EPE and PET, respectively, to ensure processing quality.

[0004] In the prior art described in the aforementioned patent, when heating the film, only one side of each film is heated. Furthermore, since the edges of the film dissipate heat faster and the edge temperature of the heating device is generally lower than the temperature at the center, it is easy to cause uneven heating of the film.

[0029] Please see the appendix Figure 1 and Figure 2As shown, this utility model provides a device for improving the uniformity of heating temperature of a membrane material, including a heating mechanism 1, an auxiliary heating mechanism 2, and a pressing mechanism 3. The heating mechanism 1 includes a heating component 11 and a heating component 2 symmetrically arranged vertically. The heating component 11 includes a heating plate 111 and a heating plate 212 symmetrically arranged vertically. The heating component 22 includes a heating plate 321 and a heating plate 422 symmetrically arranged vertically. Heating tubes 14 are laid in the heating plate 111, the heating plate 22, the heating plate 321, and the heating plate 422. The auxiliary heating mechanism 2 includes auxiliary heating frames 21 symmetrically arranged horizontally. Each auxiliary heating frame 21 has an auxiliary heating plate 22 on the side closest to the membrane material. The pressing mechanism 3 includes a pressing roller 31 and a pressing roller 32 arranged vertically. The pressing roller 31 is rotatably connected to a support frame 35, and the pressing roller 32 is slidably connected to the support frame 35 through a sliding sleeve 34.

[0030] In this embodiment, when the film is laminated, the film material flows through the heating mechanism 1, where heating components 11 and 12 can simultaneously heat both the top and bottom surfaces of each film. After being heated by the heating mechanism 1, the film flows through the auxiliary heating mechanism 2 before being pressed by the pressing mechanism 3. While flowing through the auxiliary heating mechanism 2, the edges of the film material are heated by the auxiliary heating plates 22 on both sides of the auxiliary heating mechanism 2, thereby improving the uniformity of heating the film material. Then, the films are bonded together by the pressing rollers 31 and 32 in the pressing mechanism 3 to form a composite film material.

[0031] When heating the film material, the heating components 11 and 12 in the heating mechanism 1 can heat both the top and bottom surfaces of each film simultaneously. An auxiliary heating mechanism 2 is provided between the heating mechanism 1 and the pressing mechanism 3. When the film material flows through the auxiliary heating mechanism 2, the two edges of the film material can be heated by the auxiliary heating mechanism 2. This can prevent the pressing between films from being affected by the excessive heat dissipation at the edges of the film material, increase the heating effect on the edges of the film material, and make the heating of the film material more uniform. It is worth noting that in this embodiment, the heating of the film in the heating mechanism 1 is mainly achieved by heating pipes 14 laid in the heating plates 111, 112, 121, and 122.

[0032] Guide wheels 113 are rotatably provided at the front and rear ends of heating plate 111 and heating plate 212, respectively; guide wheels 2123 are provided at the front and rear ends of heating plate 3121 and heating plate 4122, respectively.

[0033] In this embodiment, guide wheels 113 are rotatably provided at the front and rear ends of heating plate 111 and heating plate 212, respectively, and guide wheels 223 are provided at the front and rear ends of heating plate 3121 and heating plate 4122, respectively. This allows the guide wheels 113 and 223 to guide the film material when it flows between heating plate 111 and heating plate 212, and between heating plate 3121 and heating plate 4122, preventing the film from being scratched by the heating plates and causing damage.

[0034] Telescopic rods 114 are respectively provided on the left and right sides of heating plate 111. The upper end of telescopic rod 114 is connected to heating plate 111, and the lower end of telescopic rod 114 is connected to heating plate 112. Guide rods 115 are also provided at the four corners of heating plate 111. The lower end of guide rod 115 is fixedly connected to heating plate 112, and heating plate 111 is slidably connected to guide rod 115. Telescopic rods 124 are respectively provided on the left and right sides of heating plate 321. The upper end of telescopic rod 124 is connected to heating plate 321, and the lower end of telescopic rod 124 is connected to heating plate 422. Guide rods 125 are respectively provided at the four corners of heating plate 321. The upper end of guide rod 125 is fixedly connected to heating plate 321, and heating plate 422 is slidably connected to guide rod 125.

[0035] In this embodiment, the distance between heating plate 111 and heating plate 112 can be adjusted by extending and retracting the telescopic rod 114, thereby adjusting the distance between the heating plate and the film material and adjusting the heating effect on the film material as needed. The guide rod 115 makes the up-and-down movement between heating plate 111 and heating plate 112 more stable and prevents heating plate 111 and heating plate 112 from shaking.

[0036] The distance between heating plate 3 121 and heating plate 4 122 can be adjusted by extending and retracting telescopic rod 3 124. This allows for adjustment of the distance between the heating plate and the film material, thus adjusting the heating effect on the film material as needed. The function of guide rod 3 125 is to make the vertical movement of heating plate 3 121 and heating plate 4 122 more stable and prevent them from shaking.

[0037] The upper end of heating plate 111 is connected to telescopic rod 116, the upper end of telescopic rod 116 is fixedly connected to bracket 13, the upper end of heating plate 111 is fixedly connected to guide rod 117, and guide rod 117 is slidably connected to bracket 13, the lower end of heating plate 122 is connected to telescopic rod 126, the lower end of telescopic rod 126 is fixedly connected to bracket 13, and guide rod 127 is fixedly connected to the lower end of heating plate 122, and guide rod 127 is slidably connected to bracket 13.

[0038] In this embodiment, the extension and retraction of the telescopic rod 116 can drive the heating component 11 to move up and down as a whole, and the extension and retraction of the telescopic rod 126 can drive the heating component 12 to move up and down as a whole, so that the equipment can be flexibly adjusted to meet different heating needs of the film material. The function of the guide rod 117 is to improve the stability of the heating component 11 when it moves up and down on the support 13. Similarly, the function of the guide rod 127 is to improve the stability of the heating component 12 when it moves up and down on the support 13.

[0039] Please see Figure 1 and Figure 3 As shown, each auxiliary heating frame 21 has a slider 23 connected to its lower outer side. The slider 23 is slidably mounted on the slide rail 24. A lead screw 25 is also rotatably mounted inside the slide rail 24. The lead screw 25 and the slider 23 are threadedly engaged. One end of the lead screw 25 is connected to a drive motor 26. Each auxiliary heating frame 21 also has a connecting rod 27 at both ends on its outer side. The lower end of the connecting rod 27 is provided with a sliding sleeve 28, which is slidably connected to a sliding rod 29.

[0040] In this embodiment, when the film flows through the auxiliary heating mechanism 2, the auxiliary heating plates 22 on both sides of the auxiliary heating frame 21 heat the two edges of the film to improve the uniformity of heating. In addition, the drive motor 26 drives the lead screw 25 to rotate in the slide rail 24, and the lead screw 25 is threadedly engaged with the slider 23. The threads in the two sliders 23 are arranged in opposite directions. The rotation of the lead screw 25 can drive the two sliders 23 to move away from or closer to each other along the slide rail 24, thereby adjusting the distance between the auxiliary heating plates 22 on the two auxiliary heating frames 21 to meet the auxiliary heating needs of films of different widths. In addition, the distance between the auxiliary heating plates 22 on the auxiliary heating frame 21 and the edge of the film can also be adjusted flexibly as needed. When the auxiliary heating frame 21 moves, it will drive the sliding sleeve 28 at the lower end of the connecting rod 27 to slide along the sliding rod 29, thereby improving the stability of the auxiliary heating frame 21 when it moves.

[0041] Please see Figure 1 and Figure 4As shown, one end of the pressing roller 31 is connected to the drive motor 33, and both ends of the pressing roller 32 are connected to the telescopic adjustment rods 36. The lower end of the telescopic adjustment rods 36 is fixedly connected to the support frame 35.

[0042] In this embodiment, after the film is heated, it is pressed together by the pressure roller 31 and the pressure roller 32. During the pressing of the film, the pressure roller 31 is powered by the drive motor 33, which facilitates the flow of the film under the pressure of the pressure roller 31 and the pressure roller 32. The extension and retraction of the telescopic adjustment rod 36 can drive the pressure roller 32 to move up and down, and adjust the distance between the pressure roller 32 and the pressure roller 31 to adjust the pressing force on the film. This can also meet the pressing needs of films of different thicknesses. When the pressure roller 32 moves up and down, it slides up and down along the support frame 35 through the sliding sleeve 34, which can improve the stability of the pressure roller 32 during the up and down movement.

[0043] The working principle of this utility model is as follows: When the film is laminated, the film material flows through the heating mechanism 1, and the heating components 11 and 12 can heat the upper and lower surfaces of each film simultaneously. After being heated by the heating mechanism 1, before flowing through the pressing mechanism 3 for pressing, it flows through the auxiliary heating mechanism 2. When flowing through the auxiliary heating mechanism 2, the auxiliary heating plates 22 on the left and right sides of the auxiliary heating mechanism 2 can heat the edges of the film material, thereby improving the uniformity of heating the film material. Then, through the extrusion of the pressing rollers 31 and 32 in the pressing mechanism 3, the films are bonded together to form a composite film material.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
