Description

Technical Field

[0001] This utility model relates to the field of sealant production technology, and in particular to a sealant production equipment. Background Technology

[0002] Silicone sealant is a paste made by mixing polydimethylsiloxane as the main raw material with crosslinking agents, fillers, plasticizers, coupling agents and catalysts under vacuum. It cures at room temperature by reacting with water in the air to form elastic silicone rubber. During the preparation of silicone sealant, the raw materials need to be ground by a grinding device.

[0003] In the prior art, patent number CN221832529U discloses a raw material grinding device for silicone sealant production, including a grinding barrel, a grinding column, and a grinding disc. Three support legs are evenly arranged around the bottom of the grinding barrel, and a discharge pipe is correspondingly located on one side of the bottom of the grinding barrel. A motor is installed on the bottom wall of the grinding barrel, and a rotating shaft is connected to the output end of the motor. The top of the rotating shaft is connected to the grinding column and the grinding disc. The grinding barrel is divided into a first grinding barrel and a second grinding barrel. The raw material is first initially ground using the grinding column in the first grinding barrel, then further ground using the inclined plate of the second grinding barrel and the grinding protrusions on the inclined plate of the grinding disc, and finally ground a third time using the side plate of the second grinding barrel and the grinding protrusions on the side plate of the grinding disc. This process allows the raw material to be ground finer and finer, improving the grinding effect for subsequent sealant preparation.

[0004] While this technical solution allows for finer grinding of raw materials, improving grinding efficiency for subsequent sealant preparation, the large space occupied by the grinding discs inside the grinding barrel results in low space utilization and reduced efficiency in grinding polydimethylsiloxane, the raw material for sealant, thus hindering economic benefits in sealant production. Therefore, we propose a sealant production equipment. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, a sealant production device includes a grinding cylinder 1, with a feed cylinder 2 fixedly installed at the upper end of the grinding cylinder 1. A first grinding roller 8 is rotatably installed inside the grinding cylinder 1. The first grinding roller 8 is a frustum-shaped structure, narrower at the top and wider at the bottom. Multiple third grinding protrusions 12 are fixedly installed on the outer wall of the first grinding roller 8, and the third grinding protrusions 12 on the first grinding roller 8 decrease in size from top to bottom, with the spacing between adjacent third grinding protrusions 12 decreasing sequentially. Multiple second grinding rollers are also rotatably installed inside the grinding cylinder 1 around the feed cylinder 2. The grinding roller 9 has multiple first grinding protrusions 10 fixedly installed on it, and the multiple first grinding protrusions 10 and multiple third grinding protrusions 12 are arranged alternately. The inner wall of the grinding cylinder 1 also has multiple second grinding protrusions 11 that are arranged alternately with the first grinding protrusions 10. The lower end of the grinding cylinder 1 is fixedly installed with a collection bin 4. The outer wall of the collection bin 4 is provided with a discharge chute. The upper end of the collection bin 4 is fixedly installed with a screen 15. The lower ends of the first grinding roller 8 and multiple second grinding rollers 9 are rotatably connected to the screen 15.

[0026] In use, the polydimethylsiloxane raw material required for sealant production is fed into the grinding cylinder 1 through the feed cylinder 2. The polydimethylsiloxane raw material enters the interior of the grinding cylinder 1 and falls between the first grinding roller 8 and multiple second grinding rollers 9. The first grinding roller 8 and multiple second grinding rollers 9 inside the grinding cylinder 1 are always rotating. The third grinding protrusions 12 of different sizes on the first grinding roller 8 can grind the polydimethylsiloxane raw material more finely as the raw material falls from top to bottom. In addition, the multiple first grinding protrusions 10 fixedly installed on the outer wall of the second grinding roller 9 and the multiple second grinding protrusions 11 fixedly installed on the inner wall of the grinding cylinder 1 interact with each other to assist in grinding the polydimethylsiloxane. After grinding, the polydimethylsiloxane raw material falls into the interior of the collection bin 4 through the screen 15 and is then discharged outward from the discharge chute opened on the collection bin 4.

[0027] like Figure 2 As shown, a mounting box 5 is fixedly installed at the lower end of the collection bin 4. A servo motor 18 is fixedly installed at the center of the mounting box 5. The output end of the servo motor 18 passes through the center of the collection bin 4 and the screen 15 and is fixedly connected to the lower end of the first grinding roller 8. A first gear 16 is fixedly installed on the outer wall of the output end of the servo motor 18 inside the collection bin 4. The upper surface of the first gear 16 is in contact with the bottom surface of the screen 15. The bottom surface of the screen 15 and the corresponding positions of multiple second grinding rollers 9 are each rotatably installed with a second gear 17 that meshes with the first gear 16. The centers of the second grinding rollers 9 and the second gear 17 are fixedly connected. The servo motor 18 drives the first grinding roller 8 to rotate. The output end of the servo motor 18 drives the first gear 16 to rotate synchronously. The second gear 17 is meshed on the periphery of the first gear 16. When the first gear 16 rotates, multiple second gears 17 rotate synchronously, thereby driving multiple second grinding rollers 9 to rotate synchronously. The simultaneous rotation of the first grinding roller 8 and the second grinding roller 9 can enhance the grinding effect on the polydimethylsiloxane raw material.

[0028] like Figure 3 As shown, the outer wall of the output end of the servo motor 18 located inside the collection bin 4 is also fixedly installed with a collection plate 19, the bottom surface of the collection plate 19 is in contact with the bottom surface of the collection bin 4; the lower end of the collection plate 19 is provided with a flexible cleaning cotton, and when the collection plate 19 rotates, it can collect the polydimethylsiloxane raw material inside the collection bin 4 after grinding.

[0029] like Figure 2 As shown, a guide plate 6 is fixedly installed inside the discharge trough, and the guide plate 6 is inclined inside the discharge trough; the inclined guide plate 6 can guide the ground polydimethylsiloxane raw material to the outside of the protective cover 3.

[0030] like Figure 2As shown, two symmetrically arranged vibration sensors 7 are fixedly installed on the upper outer wall of the grinding cylinder 1, and a protective cover 3 is fixedly installed on the upper outer wall of the grinding cylinder 1 outside the two vibration sensors 7. The vibration sensors 7 can drive the upper end of the grinding cylinder 1 to vibrate, thereby preventing blockage between the extension block 13 and the first grinding roller 8. The protective cover 3 can protect the vibration sensors 7.

[0031] like Figure 3 As shown, an extension block 13 is fixedly installed on the upper inner wall of the grinding cylinder 1, and a plurality of fourth grinding protrusions 14 are fixedly installed on the outer wall of the extension block 13, which are interposed with the third grinding protrusion 12 on the first grinding roller 8. The extension block 13 is elastically arranged to protrude outward. When the polydimethylsiloxane raw material passes through the position of the extension block 13, the first grinding can be performed through the interaction between the extension block 13 and the first grinding roller 8.

[0032] like Figure 3 As shown, the end of the collecting plate 19 is in contact with the inner wall of the collecting bin 4, and a cleaning cotton is fixedly installed at the lower end of the collecting plate 19. The length limitation of the collecting plate 19 allows it to clean the bottom surface of the collecting bin 4 more thoroughly, and the flexible cleaning cotton allows the collecting plate 19 to better concentrate the polydimethylsiloxane raw material gathered on the bottom surface of the collecting bin 4.

[0033] The working principle of this utility model is as follows: In use, the polydimethylsiloxane raw material required for sealant production is fed into the grinding cylinder 1 through the feed cylinder 2. An extension block 13, located at the upper end of the grinding cylinder 1, protrudes outwards and is elastically designed. A fourth grinding protrusion 14 is fixedly installed on the outer wall of the extension block 13. The upper end of the first grinding roller 8 is not lower than the upper surface of the extension block 13. Multiple third grinding protrusions 12 fixedly installed on the upper end of the first grinding roller 8 are staggered with the fourth grinding protrusion 14. When the polydimethylsiloxane raw material passes the position of the extension block 13, it undergoes the first grinding process through the interaction between the extension block 13 and the first grinding roller 8. After the first grinding, the polydimethylsiloxane raw material enters the interior of the grinding cylinder 1 and falls between the first grinding roller 8 and multiple second grinding rollers 9. The first grinding roller 8 and multiple second grinding rollers 9 inside the grinding cylinder 1 are always rotating. The third grinding protrusions 12 of varying sizes on the first grinding roller 8 can... As the material falls from top to bottom, it grinds the polydimethylsiloxane raw material more finely. The multiple first grinding protrusions 10 fixedly installed on the outer wall of the second grinding roller 9 and the multiple second grinding protrusions 11 fixedly installed on the inner wall of the grinding cylinder 1 interact with each other to assist in grinding the polydimethylsiloxane. After grinding, the polydimethylsiloxane raw material falls into the inside of the collection bin 4 through the screen 15. When the servo motor 18 drives the first grinding roller 8 to rotate, the first gear 16 fixedly installed on the outer wall of the output end of the first grinding roller 8 can drive multiple second gears 17 to rotate synchronously under the action of meshing transmission, thereby driving multiple second grinding rollers 9 to rotate synchronously. During this process, the collection plate 19 fixedly connected to the outer wall of the output end of the first grinding roller 8 can rotate synchronously with the first grinding roller 8 as the axis. When the collection plate 19 rotates, it can clean the ground polydimethylsiloxane raw material collected on the bottom surface of the collection bin 4. After cleaning, the polydimethylsiloxane raw material is concentrated at the discharge trough and discharged outward.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
