Abstract
Description
Technical Field
[0001] This utility model belongs to the field of woven fabric production technology, and in particular relates to an automatic heat sealing mechanism for PE woven fabric. Background Technology
[0002] PE woven fabric (polyethylene woven fabric) is a plastic fabric made primarily of polyethylene (PE) through a weaving process. Due to its durability, water resistance, and low cost, it is widely used in agriculture, industry, construction, logistics, and other fields.
[0003] Most existing PE woven fabric heat sealing mechanisms use heating rollers to raise the temperature. However, during the process of the woven fabric moving from the heating roller to the rolling assembly, the temperature of the woven fabric will be reduced by heat transfer from the outside air, thus affecting the heat sealing effect of the PE woven fabric.
[0004] To address this issue, we propose an automatic heat-sealing mechanism for PE woven fabrics. Utility Model Content
[0005] The purpose of this invention is to solve the problem that external temperature affects the heat sealing effect in the prior art, and to propose an automatic heat sealing mechanism for PE woven fabric.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic heat-sealing mechanism for PE woven fabric includes a fixed frame. Two first heating rollers are symmetrically rotatably mounted on the upper part of the fixed frame. An arc-shaped heat reflector is rotatably mounted on the fixed frame below the first heating rollers. A locking assembly for fixing the heat reflector is mounted on the fixed frame above the first heating rollers. A second heating roller is rotatably mounted on the fixed frame below the first heating rollers. The mechanism also includes a first woven fabric, a second woven fabric, and a roller pressing assembly fixedly mounted on the lower part of the fixed frame. The first woven fabric and the second woven fabric are symmetrically arranged and sequentially wound around the first heating rollers and the second heating rollers, respectively, and are heat-sealed by the roller pressing assembly.
[0008] Preferably, the locking assembly includes a fixing plate fixedly connected to both sides of the upper part of the fixing frame, a wing bolt threaded through the fixing plate, and a threaded hole for the wing bolt to be fitted on the outer side of the heat reflector plate.
[0009] Preferably, the fixing plate has a limiting block that matches the heat reflector plate extending downwards on one side facing the middle of the fixing frame.
[0010] Preferably, the lower two sides of the fixing frame are fixedly connected with limiting plates that cooperate with the heat reflector.
[0011] Preferably, the diameter of the first heating roller is larger than that of the second heating roller, and the distance between the two second heating rollers is smaller than the distance between the two first heating rollers.
[0012] Preferably, a heating plate is fixedly connected to the fixing frame between the second heating roller and the rolling assembly, and the heating plate is located between the first woven fabric and the second woven fabric.
[0013] In summary, the technical effects and advantages of this utility model are as follows: This automatic heat sealing mechanism for PE woven fabric achieves rapid heating of the woven fabric through a heat reflector plate in conjunction with a first heating roller, while improving energy utilization efficiency. The second heating roller provides heating and heat preservation of the woven fabric after it leaves the first heating roller. Compared with existing devices, this avoids the problem of cooling of the woven fabric during its movement from the heating roller to the roller pressing assembly, thus improving the heat sealing effect.
[0014] In addition, the heat reflector can be detachably fixed on the frame by using wing bolts and threaded holes, and the heat reflector can be rotated after being unlocked by the limiting plate. This provides convenience for the first winding of the woven fabric onto the first heating roller and facilitates subsequent maintenance. Compared with the existing device, it avoids the problem of the heat reflector affecting the winding of the woven fabric and improves its practicality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-3An automatic heat-sealing mechanism for PE woven fabric includes a fixed frame 1. Two first heating rollers 2 are symmetrically rotatably mounted on the upper part of the fixed frame 1. An arc-shaped heat reflector plate 3 is rotatably mounted on the fixed frame 1 below the first heating rollers. A locking assembly for fixing the heat reflector plate 3 is mounted on the fixed frame 1 above the first heating rollers. A second heating roller 4 is rotatably mounted on the fixed frame 1 below the first heating rollers. The mechanism also includes a first woven fabric 5, a second woven fabric 6, and a roller pressing assembly 7 fixedly mounted on the lower part of the fixed frame 1. The first woven fabric 5 and the second woven fabric 6 are symmetrically arranged and sequentially wound around the first heating rollers 2 and the second heating rollers 4, respectively, and are heat-sealed by the roller pressing assembly 7. The first heating rollers 2 and 4, as well as the roller pressing assembly 7, are all existing technologies. Heat-conducting oil heating rollers, electric heating rollers, or electromagnetic heating rollers can be used. Each of the first heating rollers 2 and the roller pressing assembly 7 should be equipped with a power drive assembly to drive their rotation. These solutions are all existing technologies and are common in the heat-sealing field, and will not be elaborated further.
[0021] Reference Figure 1-3 In the automatic heat-sealing mechanism for PE woven fabric, during hot pressing, the first woven fabric 5 first passes through the first heating roller 2, which, together with the heat reflector plate 3, achieves heating. After heating, the first woven fabric 5 then passes through the second heating roller 4 to achieve heating and heat preservation. The second woven fabric 6 is symmetrically arranged with the first woven fabric 5. The second woven fabric 6 is also heated by the first heating roller 2 and the second heating roller 4. After the first woven fabric 5 and the second woven fabric 6 pass through the roller pressing assembly 7 to complete the heat sealing.
[0022] The locking assembly includes a fixing plate 8 fixedly connected to both sides of the upper part of the fixing frame 1. A wing bolt 9 is threaded through the fixing plate 8. A threaded hole 10 is opened on the outer side of the heat reflector 3 to match the wing bolt 9. The heat reflector 3 is fixed on the fixing plate 8 by the wing bolt 9 matching the threaded hole 10.
[0023] Reference Figure 1-3 The fixing plate 8 extends downward on one side facing the middle of the fixing frame 1, with a limiting block 11 that matches the heat reflector 3. The limiting block 11 provides the upper limit of rotation of the heat reflector 3. When the heat reflector 3 is in contact with the limiting block 11, the threaded hole 10 is located directly below the wing bolt 9, which facilitates operation and improves practicality.
[0024] The lower sides of the fixed frame 1 are fixedly connected with limiting plates 12 that cooperate with the heat reflector plate 3. The limiting plates 12 provide the lower limit of the rotation of the heat reflector plate 3, so as to avoid the heat reflector plate 3 from colliding with other components such as the roller pressing assembly 7 and improve safety.
[0025] Reference Figure 3The diameter of the first heating roller 2 is larger than that of the second heating roller 4, and the distance between the two second heating rollers 4 is smaller than the distance between the two first heating rollers 2. This allows the first heating roller 2 to perform the main heating work, while the second heating roller 4 performs the auxiliary heating work. Since the first heating roller 2 is the main heating roller, it requires a larger diameter. However, the angle between the first woven fabric 5 and the second woven fabric 6 entering the rolling assembly 7 needs to be small to ensure the rolling effect. The setting of the second heating roller 4 can reduce the angle between the first woven fabric 5 and the second woven fabric 6 before rolling. At the same time, the auxiliary heating can also prevent the woven fabric from cooling down. Here and in the following text, "woven fabric" refers to the first woven fabric 5 and the second woven fabric 6.
[0026] An auxiliary roller 14 is rotatably mounted on the fixed frame 1 above the first heating roller 2, thereby increasing the wrap angle and contact area between the woven fabric and the first heating roller 2, thus improving the heating efficiency.
[0027] Since there is a distance between the second heating roller 4 and the rolling assembly 7, in order to prevent the woven fabric from cooling down when it leaves the second heating roller 4, a heating plate 13 is fixedly connected to the fixing frame 1 between the second heating roller 4 and the rolling assembly 7. The heating plate 13 is located between the first woven fabric 5 and the second woven fabric 6. The heating plate 13 heats and keeps the woven fabric warm before rolling, thereby further improving the heat sealing efficiency.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
