Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of degassing mechanisms, in particular to a degassing mechanism for calendering a heat-conducting silicone gasket. Background Art
[0002] Thermal conductive silicone gaskets are liquid or semi-solid materials before solidification. Their viscosity ranges from mud to paste, and the viscosity is very high. During the calendering process, obvious bubbles will appear. At present, degassing is basically carried out in a vacuum environment. For slurries with high viscosity, it is difficult to quickly discharge the bubbles inside, and the degassing efficiency is low. The vacuum degree must be increased to carry out the degassing. However, when the vacuum degree is increased, the boiling point of water in the slurry is also reduced, resulting in excessive evaporation of water at room temperature, which reduces the quality of the slurry.
[0003] After searching, the Chinese patent application number CN215282996U discloses a thermally conductive silicone gasket calendering molding degassing mechanism, including a degassing component fixedly arranged on the upper part of the working chamber, the degassing component includes a piston cylinder fixedly connected to the middle of the top of the working chamber, a piston is movably arranged inside the piston cylinder, and the bottom of the piston is fixedly connected to a piston rod that passes through the top of the working chamber.
[0004] However, it was found in actual use that in a vacuum environment, the intermolecular interaction force of the thermally conductive silicone raw material would be enhanced. Especially for some thermally conductive silicone raw materials with strong viscosity, the bubbles in the thermally conductive silicone raw materials are filtered out through a conical bubble net. Due to the strong viscosity of the thermally conductive silicone raw materials, the screening time will be too long. Long waiting time for screening will increase the production cycle and reduce production efficiency. Utility Model Content
[0005] The purpose of the utility model is to solve the problem in the prior art that the sieving time is too long due to the strong viscosity of the thermally conductive silicone raw material. The long sieving waiting time will increase the production cycle and reduce production efficiency. A thermally conductive silicone gasket calendering molding degassing mechanism is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A thermally conductive silicone gasket calendering and degassing mechanism comprises a working cylinder, and also comprises: an extension rod rotatably connected to the working cylinder, wherein a filter bubble net is fixedly connected to the bottom of the extension rod, a driving machine is connected to the working cylinder for lifting, and the extension rod is fixedly connected to the output end of the driving machine; a limit plate fixedly connected to the driving machine through a connecting rod, wherein a scraper is fixedly connected to the bottom of the limit plate, the scraper is in contact with the surface of the filter bubble net, an arc-shaped cleaning plate is fixedly connected to the scraper, and the arc-shaped cleaning plate is in contact with the inner wall of the working cylinder.
[0008] In order to facilitate the limiting of the electric push rod, preferably, a mounting cylinder is fixedly connected to the working cylinder, the mounting cylinder is communicated with the working cylinder, the electric push rod is fixedly connected inside the mounting cylinder, and the driving motor is fixedly connected to the output end of the electric push rod.
[0009] In order to facilitate fixing of the scraper, further, a fixing plate is fixedly connected to the bottom of the limiting plate, and the scraper is fixedly connected to the fixing plate.
[0010] In order to facilitate vacuuming of the working cylinder, preferably, a placement box is fixedly connected to the side wall of the installation cylinder, a vacuum pump is fixedly connected inside the placement box, and the vacuum pump is connected to the working cylinder through a pipeline.
[0011] In order to facilitate cooling of the working cylinder, preferably, a cooling component is provided in the working cylinder.
[0012] In order to improve the lifting effect of the electric push rod, preferably, the electric push rod is symmetrically arranged in two groups.
[0013] Compared with the prior art, the utility model provides a thermal conductive silicone gasket calendering molding degassing mechanism, which has the following beneficial effects:
[0014] 1. The thermal conductive silicone gasket is calendered to form a degassing mechanism. The scraper can scrape the surface of the filter bubble net to facilitate scraping of the raw materials with strong viscosity, keep the filter bubble net unobstructed, and prevent the thermal conductive silicone raw materials from clogging the filter mesh holes, thereby improving the screening efficiency of the filter bubble net, reducing the waiting time for screening, reducing the production cycle, and improving production efficiency;
[0015] 2. The degassing mechanism of the thermally conductive silicone gasket calendering molding can indirectly scrape the inner wall of the working cylinder by using an arc-shaped cleaning plate to reduce the adhesion of raw materials.
[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can scrape the raw materials with strong viscosity, keep the filter bubble net unobstructed, and prevent the thermal conductive silicone raw materials from clogging the filter mesh holes, thereby improving the screening efficiency of the filter bubble net, reducing the waiting time for screening, shortening the production cycle, and improving production efficiency.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0024] Example:
[0025] Reference Figure 1-Figure 4 A thermally conductive silicone gasket calendering molding degassing mechanism includes a working cylinder 1, in which a cooling component is installed. The cooling component is wound around the inside of the working cylinder 1 by a spiral pipe, and a coolant or cooling water can be introduced from the outside to cool the raw materials in the working cylinder 1. A mounting cylinder 2 is also installed on the working cylinder 1, and the mounting cylinder 2 is connected to the working cylinder 1, and a placement box 8 is also installed on the side wall of the mounting cylinder 2, and a vacuum pump 801 is also arranged in the placement box 8, and the vacuum pump 801 is connected to the working cylinder 1 through a pipe, and the vacuum pump 801 can be used to evacuate the working cylinder 1.
[0026] In addition, two groups of symmetrical electric push rods 7 are installed in the installation cylinder 2, and a driving machine 3 is installed at the output end of the electric push rod 7. An extension rod 301 is also installed at the output end of the driving machine 3. The driving machine 3 can be used to drive the extension rod 301 to rotate, and the electric push rod 7 can control the lifting and lowering of the driving machine 3. The extension rod 301 is then extended to the inside of the working cylinder 1, and a filter bubble net 101 is installed at the bottom of the extension rod 301. A connecting rod 401 is also installed on the driving machine 3, and the other end of the connecting rod 401 extends to the working cylinder 1 and is fixedly installed with a limit plate 4. A scraper 5 is also installed at the bottom of the limit plate 4 through a fixed plate 501, and the scraper 5 is in contact with the surface of the filter bubble net 101.
[0027] Here, when the follicle net 101 needs to rise, the switch of the driving machine 3 is started so that it can drive the extension rod 301 to rotate, and then the switch of the electric push rod 7 is started so that it drives the driving machine 3 to rise, so that the follicle net 101 can automatically rotate during the rising process. At the same time, during the rising process of the follicle net 101, the limit plate 4 always rises synchronously with the follicle net 101, and during the rotation of the follicle net 101, the scraper 5 is always in a fixed state, so that the surface of the follicle net 101 can be scraped to facilitate the scraping of raw materials with strong viscosity, keep the follicle net 101 unobstructed, and prevent the thermal conductive silicone raw material from clogging the filter mesh holes, thereby improving the screening efficiency of the follicle net 101, reducing the waiting time for screening, reducing the production cycle, and improving production efficiency.
[0028] An arc-shaped cleaning plate 6 is also installed on the scraper 5, and the arc-shaped cleaning plate 6 is in contact with the inner wall of the working cylinder 1. During the movement of the filter bubble net 101, the inner wall of the working cylinder 1 can be indirectly scraped to reduce the adhesion of the raw materials. In a vacuum environment, the thermal conductive silicone raw material may adhere to the inner wall of the working cylinder 1. This is because under vacuum conditions, the interaction force between molecules will be enhanced, causing the substance to adhere more easily to the container wall. In particular, for some thermal conductive silicone raw materials with strong viscosity, it is more likely to produce adhesion in a vacuum environment, and the arc-shaped cleaning plate 6 can scrape the raw materials on the inner wall of the working cylinder 1.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
