Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a three-roll grinding equipment for the production of silicone additives. Background Technology

[0002] Silicone additive production refers to the process of mixing and reacting basic silicone with functional additives to produce silicone additive products with specific properties and applications. In order to facilitate the grinding of raw materials during production and processing, a three-roll milling machine for silicone additive production is required.

[0003] Three-roll milling equipment for silicone additive production refers to specialized equipment designed for the production process of silicone additives. Through the precise cooperation and friction between three horizontally arranged rollers, it efficiently and uniformly grinds and refines silicone raw materials and additives to meet the strict requirements of raw material fineness in production.

[0004] Currently available three-roll milling equipment for silicone additive production uses multiple telescopic rods corresponding to the milling rollers to adjust the distance between them, thereby controlling the milling effect. However, in actual use, this device is difficult to guarantee the stability of the entire milling process when adjusting the degree of milling, resulting in uneven coarseness of the milled material and reducing the reliability of the device. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a three-roll grinding equipment for the production of silicone additives, aiming to improve the problem that it is difficult to ensure the uniformity of the material after grinding when adjusting the grinding rollers in the existing grinding equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-roll grinding device for producing silicone additives, comprising a grinding plate, a threaded rod rotatably connected to the front side of the outer wall of the grinding plate, a U-shaped block threadedly connected to the top of the threaded rod, telescopic plates rotatably connected to the left and right sides of the inner wall of the U-shaped block, a second grinding roller rotatably connected to the rear side of the telescopic plate penetrating the grinding plate, a first grinding roller rotatably connected to the inner side of the grinding plate, gears fixedly connected to the outer sides of both the first and second grinding rollers, and multiple gears meshing and transmitting power between each other, a screening seat connected to the bottom of the grinding plate, a hollow cover connected to the outer side of the grinding plate, a motor fixedly connected to the upper and lower sides of the inner wall of the hollow cover, a rotating column fixedly connected to the output end of the motor, a transmission belt provided on the outer side of the rotating column, and two rotating columns being connected by transmission belts, a motor fixedly connected to the rear side of the grinding plate, the output end of the motor penetrating the grinding plate and fixedly connected to the corresponding gear, and a positioning mechanism provided at the bottom of the screening seat for moving and positioning the device.

[0007] Through the above technical solution: after the motor is started, the gear drives the first grinding roller to start rotating, and through the meshing transmission mechanism, it drives the second grinding roller to grind the material synchronously. At the same time, the threaded rod drives the U-shaped plate to move up and down through the threaded connection. This movement further causes the telescopic plate to rotate, thereby adjusting the position of the second grinding roller relative to the first grinding roller, so as to change the degree and position of grinding as needed. After grinding, the material is discharged after being intercepted by the screening seat, while the unqualified material is sent into the hollow hood. In the hollow hood, the motor drives the rotating column to rotate, and through the transmission belt, these unqualified materials are sent back to the grinding plate for re-grinding, ensuring that the ground material has a high degree of uniformity and stability.

[0008] As a further description of the above technical solution:

[0009] The positioning mechanism includes a hollow plate, which is fixedly connected to the bottom of the screening seat. A worm gear is rotatably connected to the bottom right side of the inner wall of the hollow plate. Worm wheels are rotatably connected to the front and rear sides of the right end of the inner wall of the hollow plate. The worm wheels mesh with the worm gear for transmission. A rotating rod is fixedly connected to the left side of the worm wheel. Fixed blocks are fixedly connected to the left and right sides of the outer wall of the rotating rod. A traveling wheel is rotatably connected to the outer side of the fixed blocks.

[0010] The above technical solution involves rotating a worm gear, which drives the worm wheel to rotate via a meshing mechanism. The rotation of the worm wheel further drives the rotating rod to rotate, which in turn drives the fixed block to move, causing the traveling wheel to contact the ground. This allows the device to move easily, and when the device needs to be fixed, the traveling wheel can be easily retracted to ensure that the device remains stable. This makes it easy to move and position the device.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the screening seat is fixedly connected with handles on all four sides, and the outer side of the handles is fixedly connected with protective sleeves.

[0013] The above technical solution allows for easy handling and storage of the device through the handle and protective sleeve.

[0014] As a further description of the above technical solution:

[0015] A bracket is fixedly connected to the bottom of the motor, and the outer side of the bracket is fixedly connected to the grinding plate.

[0016] The above technical solution can improve the structural strength and installation stability of the device by using a bracket.

[0017] As a further description of the above technical solution:

[0018] The grinding plate is provided with a movable door at the top. Hinges are fixedly connected to the front and rear sides of the top of the movable door. The movable door is rotatably connected to the grinding plate through the hinges. Guide rods are fixedly connected to the left and right sides of the front end of the grinding plate. The U-shaped block is slidably connected to the guide rods.

[0019] The above technical solution allows for the opening and closing of the movable door via hinges, facilitating internal maintenance, and enhances the stability of the U-shaped block's movement via guide rods.

[0020] As a further description of the above technical solution:

[0021] A controller is fixedly connected to the left side of the grinding plate, and the controller is electrically connected to the motor.

[0022] The above technical solution enables the controller to control the starting and switching of the motor.

[0023] As a further description of the above technical solution:

[0024] Positioning blocks are fixedly connected to the front and rear sides of the left end of the hollow plate, and positioning holes are opened on the outer side of the positioning blocks.

[0025] The above technical solution allows for easy device fixation by inserting a threaded component into the positioning hole.

[0026] As a further description of the above technical solution:

[0027] The hollow plate has knobs rotatably connected to both the front and rear sides of its outer wall. The outer side of each knob passes through the hollow plate and is fixedly connected to the worm gear.

[0028] The above technical solution allows the worm gear to be manually operated by turning the knob.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, after starting the motor, the gear drives the first grinding roller to rotate, and through meshing transmission, it drives the second grinding roller to grind the material synchronously. At the same time, the threaded rod moves the U-shaped plate up and down through the threaded connection, drives the telescopic plate to rotate and adjusts the position of the second grinding roller along the first grinding roller, so as to change the degree and position of grinding. The ground material is intercepted and discharged by the screening seat, and the unqualified material is sent into the hollow cover, driven by the motor to rotate the rotating column, and then sent back into the grinding plate for re-grinding through the transmission belt. This can ensure the uniformity and stability of grinding, thereby improving the reliability of the device.

[0031] 2. In this utility model, the rotating worm drives the worm wheel to rotate through the meshing mechanism. This rotation of the worm wheel in turn drives the rotating rod to rotate. As the rotating rod rotates, the fixed block is also driven up, causing the traveling wheel to contact the ground, which facilitates the movement of the device. At the same time, when the traveling wheel needs to be retracted, it can also ensure the stable fixation of the device, which can facilitate the movement and positioning of the device, thereby improving the convenience of the device.

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.

[0040] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a three-roll grinding device for producing silicone additives, comprising a grinding plate 1. A threaded rod 7 is rotatably connected to the front side of the outer wall of the grinding plate 1. A U-shaped block 8 is threadedly connected to the top of the threaded rod 7. Rotating the threaded rod 7 can drive the U-shaped block 8 to move up and down. Telescopic plates 9 are rotatably connected to the left and right sides of the inner wall of the U-shaped block 8. The rear side of the telescopic plate 9 passes through the grinding plate 1 and is rotatably connected to a second grinding roller 6. As the U-shaped block 8 moves, it can drive the telescopic plate 9 to rotate, thereby driving the second grinding roller 6 to rotate. A first grinding roller 5 is rotatably connected to the inner side of the grinding plate 1. Gears 4 are fixedly connected to the outer sides of both the first grinding roller 5 and the second grinding roller 6. Multiple gears 4 mesh and drive each other. Through the meshing of the gears 4, the first grinding roller 5 can rotate. When activated, the second grinding roller 6 is rotated. The bottom of the grinding plate 1 is connected to the screening seat 3. The outer side of the grinding plate 1 is connected to the hollow cover 11. The upper and lower sides of the inner wall of the hollow cover 11 are fixedly connected to the motor 14. The output end of the motor 14 is fixedly connected to the rotating column 12. The outer side of the rotating column 12 is provided with a transmission belt 13. Starting the motor 14 can drive the rotating column 12 to rotate and drive the transmission belt 13 on it to rotate.

[0041] Specifically, the starter motor 15 drives the corresponding gear 4 and the first grinding roller 5 connected to it to start rotating. Through the meshing of multiple gears 4, the second grinding roller 6 will also rotate synchronously to grind the material. At the same time, the rotating threaded rod 7 will use the threaded connection to make the U-shaped block 8 move up and down, thereby driving the telescopic plate 9 to rotate. As the telescopic plate 9 moves, the second grinding roller 6 will adjust its position along the trajectory of the first grinding roller 5, thereby changing the position and degree of grinding. The ground material will be intercepted and discharged by the screening seat 3, while the material that does not meet the requirements will be sent into the hollow cover 11. At this time, the starter motor 14 will drive the rotating column 12 to rotate, and the transmission belt 13 will send the material back to the grinding plate 1 for further grinding.

Fixed blocks 204 are fixedly connected to the left and right sides of the outer wall of the rotating rod 203. A traveling wheel 205 is rotatably connected to the outer side of the fixed block 204. When the traveling wheel 205 contacts the ground, it can facilitate the movement of the device.

[0043] Specifically, the rotating worm 201 drives the worm wheel 202 to rotate through meshing. Subsequently, the rotation of the worm wheel 202 drives the rotating rod 203 to rotate as well. The rotation of the rotating rod 203 further causes the fixed block 204 and the traveling wheel 205 on it to rotate, so that the traveling wheel 205 contacts the ground, which facilitates the movement of the device. When the traveling wheel 205 needs to be retracted, this mechanism also facilitates the fixation of the device.

The worm gear 202 can be manually rotated by operating the knob 20.

[0048] Working principle: Before using the device, the motor 15 is started to drive the corresponding gear 4 and the first grinding roller 5 on it to rotate. At the same time, through the meshing transmission between multiple gears 4, the second grinding roller 6 is driven to rotate synchronously to grind the material. At this time, rotating the threaded rod 7 can drive the U-shaped block 8 to move up and down through the threaded connection, thereby driving the telescopic plate 9 to rotate. As the telescopic plate 9 moves, it can drive the second grinding roller 6 to rotate along the first grinding roller 5 to adjust the grinding position and grinding degree. The ground material will be intercepted and discharged by the screening seat 3. The unqualified material intercepted will be sent into the hollow cover 11, and the motor 14 is started to drive the rotating column 12 to rotate, so that the material is sent back into the grinding plate 1 for re-grinding through the transmission belt 13 on it.

[0049] Furthermore, by rotating the worm 201, the worm wheel 202 can be driven to rotate through meshing transmission. At this time, the rotation of the worm wheel 202 can drive the rotating rod 203 to rotate. As the rotating rod 203 rotates, it can drive the fixed block 204 on it to rotate, so that the traveling wheel 205 contacts the ground, so as to facilitate the movement of the device and to facilitate the fixing of the device when the traveling wheel 205 is retracted.
