Description

Technical Field

[0001] The utility model relates to the technical field of silica gel sheet production, in particular to a silica gel sheet material calender. Background Art

[0002] Silica gel, also known as silica gel, is a granular porous silicon dioxide hydrate, an amorphous substance with a transparent or milky white appearance. It is made by washing and drying sodium silicate after adding acid. It has stable chemical properties and is non-flammable.

[0003] The calender is composed of two or more rollers arranged in a certain form, which can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite film, graphite sheet, absorbing material, shielding material, magnetic material, non-ferrous metal material, etc. Hot pressing is a machine that presses and stretches rubber, silicone, silicone rubber, phase change material, PTFE or plastic into a film with a certain thickness and surface shape at a certain temperature, and can also coat fiber curtain canvas or steel cord fabric with glue;

[0004] When processing silicone sheets, a calender is required for calendering. However, before the existing silicone sheets are conveyed to the calender, the outer surface of the silicone sheets is easily adhered to particulate impurities such as granular dust. When the silicone sheets are conveyed to the heating equipment for heat treatment and calendering, the surface is easily dented due to the particles, which will reduce the quality of the silicone sheets and affect the production quality of the silicone sheets. Utility Model Content

[0005] The purpose of the utility model is to provide a silica gel sheet calender to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a silicone sheet calender comprises a workbench, two groups of symmetrically arranged primary columns are fixedly installed on one side of the upper surface of the workbench, a material guide roller is rotatably installed between the two groups of the primary columns through bearings, two groups of symmetrically arranged secondary columns are fixedly installed on one side of the primary column and located on the upper surface of the workbench, empty grooves are opened above the two groups of the secondary columns, a lower scraper is fixedly installed below the empty groove and between the two groups of the secondary columns, a smooth rod is fixedly installed in the empty groove on one side, and a primary screw is rotatably installed in the empty groove on the other side through bearings, a movable plate is sleeved on the outside of the smooth rod and the primary screw, the movable plate on the smooth rod is slidably connected to the smooth rod, and the movable plate on the other side is threadedly connected to the primary screw, an upper scraper is fixedly installed between the two groups of the movable plates, and two groups of symmetrically arranged side plates are fixedly installed at one end of the secondary column and located on the upper surface of the workbench.

[0007] Preferably, a feed guide roller is rotatably mounted between the front ends of the two groups of side plates via a bearing.

[0008] Preferably, square grooves are provided on the side walls of the two groups of side panels, and movable guide rods are fixedly installed on both sides of the two groups of square grooves.

[0009] Preferably, a primary pressure plate is slidably sleeved between the movable guide rods on one side, and a secondary pressure plate is sleeved between the movable guide rods on the other side.

[0010] Preferably, a plurality of evenly distributed pressure rollers are rotatably mounted between the primary pressure plate and the secondary pressure plate via bearings, and the lengths of the plurality of pressure rollers increase sequentially from the feed end to the discharge end of the feed guide roller.

[0011] Preferably, a threaded hole is opened in the middle of the secondary pressure plate, a secondary screw is threadedly connected in the threaded hole, and a secondary hand wheel is fixedly connected to a side plate on one side through the top end of the secondary screw.

[0012] Preferably, a primary handwheel is fixedly mounted on the top end of the primary screw.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model can scrape and clean the upper and lower surfaces of the silica gel by means of the upper scraper and the lower scraper, thereby effectively removing impurities on the outer surface of the silica gel, improving the subsequent calendering quality, avoiding particle depression, and effectively improving the subsequent production quality of the silica gel sheet. The upper scraper is driven to adjust its position by the up and down movement of the movable plate. In this way, the distance between the two scrapers can be adjusted, so that it can be used for scraping silica gels of different thicknesses. At the same time, the pressure applied by the scraper can be adjusted to prevent the silica gel from being torn and damaged by excessive pressure, thereby greatly improving the scope of application of the utility model and reducing the limitations of use.

[0015] The utility model can perform calendering on the silicone material by means of the pressure roller, and the pressure roller can be adjusted up and down at the same time. The calendering pressure of the pressure roller can also be adjusted during the up and down height adjustment process, and has dual dynamic use characteristics. While adjusting the pressure, it can also be used for silicone materials of different thicknesses, which greatly improves the processing quality and application range of calendering and has a good use effect.

[0016] Moreover, the lengths of the plurality of pressure rollers increase successively from the feed end to the discharge end of the feed guide roller, thereby realizing time-difference rolling of the silicone material, facilitating the escape and overflow of bubbles in the flowing thermally conductive silicone, reducing the bubbling problem generated after the sheet is rolled, improving the processing quality, and having a better use effect.

[0027] In actual use, please refer to the instructions for details. Figure 5 As shown, the heat-treated silicone sheet can be conveyed by being closely attached to the bottom of the guide roller 3, thereby improving the conveying and feeding quality;

A primary hand wheel 19 is fixedly installed on the top of the primary screw rod 9. The outer parts of the polished rod 8 and the primary screw rod 9 are both sleeved with a moving plate 10. The moving plate 10 on the polished rod 8 is slidably connected to the polished rod 8, and the moving plate 10 on the other side is threadedly connected to the primary screw 9. An upper scraper 7 is fixedly installed between the two groups of moving plates 10;

[0029] According to the above structural design, the silicone material conveyed by the guide roller 3 enters between the upper scraper 7 and the lower scraper 6. During the continuous conveying process, the upper scraper 7 and the lower scraper 6 will perform scraping and cleaning treatment on the upper and lower surfaces of the silicone, thereby effectively removing impurities on the outer surface of the silicone, improving the subsequent calendering quality, avoiding particle depression, and effectively improving the subsequent production quality of silicone sheets;

[0030] A primary screw rod 9 is provided on one side of the upper scraper plate 7, and the primary screw rod 9 can be rotated by a primary hand wheel 19. When the primary thread 9 rotates, the movable plate 10 connected to the same side thread will move up and down, thereby driving the upper scraper plate 7 to adjust its position by the up and down movement of the movable plate 10. In this way, the distance between the two scrapers can be adjusted, so that it can be used for scraping silicone with different thicknesses, which greatly improves the scope of application of the utility model and reduces the limitations of use.

[0031] In this embodiment, two sets of symmetrically arranged side plates 11 are fixedly installed at one end of the secondary column 4 and located on the upper surface of the workbench 1, and a feed guide roller 12 is rotatably installed between the front ends of the two sets of side plates 11 through bearings, and the feed guide roller 12 can be used for calendering feeding;

[0032] Furthermore, square grooves 13 are provided on the side walls of the two sets of side plates 11, and movable guide rods 14 are fixedly installed on both sides of the two sets of square grooves 13. A primary pressure plate 15 is slidably sleeved between the movable guide rods 14 on one side, and a secondary pressure plate 16 is sleeved between the movable guide rods 14 on the other side;

[0033] Furthermore, a plurality of uniformly distributed pressure rollers 17 are rotatably mounted between the primary pressure plate 15 and the secondary pressure plate 16 via bearings, and the lengths of the plurality of pressure rollers 17 increase sequentially from the feed end to the discharge end of the feed guide roller 12 .

[0036] At the same time, a secondary screw 18 is arranged on the secondary pressure plate 16 of the pressure roller 17, and the secondary screw 18 can be rotated under the drive of the secondary hand wheel 20. When the secondary screw 18 rotates, the secondary pressure 16 threadedly connected thereto will drive a plurality of pressure rollers 17 to adjust up and down, so that it can be applied to silicone materials of different thicknesses for pressurization. At the same time, the up and down height adjustment can also adjust the calendering pressure of the pressure roller 17, which has dual dynamic use characteristics. While adjusting the pressure, it can also be applied to silicone materials of different thicknesses, which greatly improves the processing quality and application range of calendering and has a good use effect.

[0037] Moreover, the lengths of the plurality of pressure rollers 17 increase successively from the feeding end to the discharging end of the feeding guide roller 12, thereby realizing time-difference rolling of the silicone material, facilitating the escape and overflow of bubbles in the flowing thermally conductive silicone, reducing the bubbling problem generated after the sheet is rolled, improving the processing quality, and having a better use effect.

[0038] Working principle: The heat-treated silicone material is attached to the instruction manual. Figure 5The feeding and conveying posture shown is continuously conveyed and passed through the calender of the utility model under the drive of the external winding or conveying equipment;

[0039] During the continuous feeding and conveying process of the silicone sheet, the silicone sheet passes through the upper scraper 7 and the lower scraper 6. During the continuous conveying process, the upper scraper 7 and the lower scraper 6 will perform scraping and cleaning treatment on the upper and lower surfaces of the silicone, thereby effectively removing impurities on the outer surface of the silicone, improving the subsequent calendering quality, avoiding particle depression, and effectively improving the subsequent production quality of the silicone sheet;

[0040] A primary screw 9 is provided on one side of the upper scraper 7, and the primary screw 9 can be rotated by a primary hand wheel 19. When the primary thread 9 rotates, the movable plate 10 connected to the same side thread moves up and down, thereby driving the upper scraper 7 to adjust its position by the up and down movement of the movable plate 10. In this way, the distance between the two scrapers can be adjusted, so that it can be used for scraping silicone with different thicknesses, which greatly improves the scope of application of the utility model and reduces the limitations of use.

[0041] The clean silicone material after scraping can be fed through the feed guide roller 12 for calendering. The silicone material passes through the feed guide roller 12 and enters under each pressure roller 17, so that the silicone material can be calendered by the set pressure roller 17.

[0042] At the same time, a secondary screw 18 is arranged on the secondary pressure plate 16 of the pressure roller 17, and the secondary screw 18 can be rotated under the drive of the secondary hand wheel 20. When the secondary screw 18 rotates, the secondary pressure 16 threadedly connected thereto will drive a plurality of pressure rollers 17 to adjust up and down, so that it can be applied to silicone materials of different thicknesses for pressurization. At the same time, the up and down height adjustment can also adjust the calendering pressure of the pressure roller 17, which has dual dynamic use characteristics. While adjusting the pressure, it can also be applied to silicone materials of different thicknesses, which greatly improves the processing quality and application range of calendering and has a good use effect.

[0043] Moreover, the lengths of the plurality of pressure rollers 17 increase successively from the feeding end to the discharging end of the feeding guide roller 12, thereby realizing time-difference rolling of the silicone material, facilitating the escape and overflow of bubbles in the flowing thermally conductive silicone, reducing the bubbling problem generated after the sheet is rolled, improving the processing quality, and having a better use effect.
