Abstract
Description
Technical Field
[0001] This utility model relates to a melting device for heating adhesive blocks on both sides. Background Technology
[0002] The first step in the production of high-performance fiber prepregs is coating. In the traditional process, a low-temperature solid resin is placed in an oven and heated to a molten state. Then, it is manually poured into the glue tank of the coating line and coated with glue to produce a film.
[0003] The wire mesh melting device is an online melting device used in coating production lines. Low-temperature solid resin is placed on the device to melt, and the melted resin is then transported to the glue tank of the coating machine for the production of the adhesive film.
[0004] There are various methods for melting adhesive, including offline oven melting, online dispensing rack melting, online double-roller melting, and online mesh curtain melting. Optimal process requirements necessitate melting capacity matching the production line requirements and precise control of the adhesive temperature to achieve early melting and use. Furthermore, it should facilitate cleaning and replacement of easily damaged parts such as the mesh curtain. This necessitates improving melting capacity, controlling the dispensing speed, and overcoming the problems of material accumulation and roll-up in traditional mesh curtain melting tanks. Against this backdrop, a new enhanced mesh curtain melting system has emerged.
[0005] Existing screen glue melting systems have the following problems: 1. In traditional screen glue melting systems, a heating plate is installed at the bottom of the screen, and there is a baffle at the resin outlet. During processing, the resin softens and overflows the baffle, causing the system to malfunction. 2. After the molten resin exits the outlet, it is transferred to the glue tank along with the screen. The traditional transfer path is open, making it difficult to control the resin temperature. Utility Model Content
[0006] The purpose of this invention is to provide a melting device for heating adhesive blocks on both sides, so as to solve the technical problems mentioned in the background art.
[0007] The technical solution to achieve the purpose of this utility model is: a glue melting device for double-sided heating of glue blocks, including a frame and a heat conduction system disposed on the frame. A glue melting tank is disposed on the frame. The heat conduction system includes a first heating component and a second heating component. The first heating component is adapted to heat and melt the glue block at the bottom and convey the melted glue to the coating device. The second heating component is disposed at the outlet of the glue melting tank.
[0008] Furthermore, the first heating assembly includes a circulating mesh curtain, a mesh curtain driving device, a heating plate assembly, and multiple conveying rollers. The circulating mesh curtain passes around the multiple conveying rollers in sequence. The mesh curtain driving device drives at least one conveying roller to rotate, thereby moving the circulating mesh curtain. The heating plate assembly is disposed inside the circulating mesh curtain.
[0009] Furthermore, the heating plate assembly includes a first heating plate disposed at the bottom of the melting tank, a second heating plate disposed at the front end of the first heating plate along the conveying direction of the circulating mesh curtain, and a third heating plate disposed at the rear end of the first heating plate.
[0010] Furthermore, the third heating plate is provided with a heat-insulating cover that cooperates with the third heating plate.
[0011] Furthermore, the second heating component includes a heating roller, which is rotatably disposed above the circulating mesh curtain.
[0012] Furthermore, a scraper is provided on the side of the heating roller away from the melting tank.

[0037] (Example 1)
[0038] See Figure 1-3 A melting device for heating glue blocks on both sides includes a frame and a heat conduction system mounted on the frame. A melting tank 1 is mounted on the frame. The heat conduction system includes a first heating component 2 and a second heating component 3. The first heating component 2 is adapted to preheat, melt the glue block, and convey the melted glue to the coating device. The second heating component 3 is located at the outlet of the melting tank 1.
[0039] Specifically, the first heating component 2 includes a circulating mesh curtain 2-1, a mesh curtain driving device (not shown in the figure), a heating plate assembly, and multiple conveying rollers 2-2. The circulating mesh curtain 2-1 passes around the multiple conveying rollers 2-2 in sequence. The mesh curtain driving device drives at least one conveying roller 2-2 to rotate so as to move the circulating mesh curtain 2-1. The heating plate assembly is located inside the circulating mesh curtain 2-1.
[0040] The heating plate assembly includes a first heating plate 2-3 disposed at the bottom of the melting tank 1, a second heating plate 2-4 disposed at the front end of the first heating plate 2-3 along the conveying direction of the circulating screen 2-1, and a third heating plate 2-5 disposed at the rear end of the first heating plate 2-3, to ensure that the temperature of the circulating screen 2-1 in contact with the resin is constant and controllable.
[0041] The bottom of the melting tank 1 is a first heating plate 2-3, and baffles 6 are provided on both sides. The baffles 6 are made of PTFE and the spacing between the baffles 6 is adjustable to adjust the melting width.
[0042] A heat insulation cover 4 is provided at the third heating plate 2-5 to cooperate with the third heating plate 2-5. Hot air can be passed through the heat insulation cover 4 or heating elements can be installed inside to further insulate the heat.
[0043] The second heating component 3 includes a heating roller 3-1, which is rotatably mounted above the circulating mesh curtain 2-1. In this embodiment, the heating roller 3-1 can heat the side of the resin. The rotation of the heating roller 3-1 can prevent the molten resin from overturning over the heating roller 3-1. As shown in the figure, the heating roller 3-1 rotates clockwise. At the same time, a scraper 3-2 is provided on the side of the heating roller 3-1 away from the melting tank 1 to scrape the resin off the heating roller 3-1.
[0044] The second heating component 3 also includes a lifting device 5. The lifting device 5 can use a handwheel and screw lifting mechanism or other mechanisms to control the lifting of the heating roller 3-1, adjust the distance between the heating roller 3-1 and the circulating screen 2-1, and effectively control the resin output.
[0045] In this embodiment, a second heating component 3 is provided at the outlet of the melting tank 1. The bottom and sides of the resin are heated by the first heating plate 2-3 and the heating roller 3-1 respectively, which enhances the melting capacity, ensures that the resin melts and is used as soon as possible, and prevents the resin from overturning the partition when it reaches the resin outlet, thus affecting the normal operation of the entire device.
[0046] (Example 2)
[0047] The difference between this embodiment and Embodiment 1 is that the second heating component 3 includes a fourth heating plate instead of a heating roller 3-1, and the fourth heating plate is obliquely positioned above the circulating mesh curtain 2-1. Similarly, the second heating component 3 also includes a lifting device 5, which can use a handwheel and screw lifting mechanism or other mechanisms to control the lifting and lowering of the fourth heating plate, adjusting the distance between the fourth heating plate and the circulating mesh curtain 2-1. This embodiment, by using a fourth heating plate, can also heat the side of the resin, and at a lower cost.
[0048] (Example 3)
[0049] The difference between this embodiment and Embodiment 2 is that the second heating component 3 further includes a rotating device, which drives the fourth heating plate to rotate. Not only can the distance between the fourth heating plate and the circulating mesh curtain 2-1 be adjusted via the lifting device 5, but the distance can also be adjusted by driving the heating plate to rotate via the rotating device. Alternatively, both the lifting device 5 and the rotating device can be used to achieve the same effect.
[0050] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
