Description

Technical Field

[0001] This utility model relates to the field of three-roll mills, and in particular to a three-roll mill with a screening function. Background Technology

[0002] Three-roll mills, also known simply as three-roll grinders, can be divided into experimental three-roll mills and production three-roll mills. Three-roll mills are suitable for manufacturing pastes such as paints, inks, pigments, and plastics. The working principle of a three-roll mill is as follows: The three-roll mill achieves the grinding effect by the mutual extrusion and friction at different speeds of the surfaces of three horizontal rollers.

[0003] However, existing three-roll mills have some problems in the grinding process. They require additional equipment to screen the ground materials, which increases the production process and cost. Secondly, after screening, the materials often accumulate in one place due to their viscosity, making collection inconvenient. To solve the above problems, we propose a three-roll mill with screening function. Utility Model Content

[0004] The main purpose of this invention is to provide a three-roll mill with a screening function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A three-roll mill with screening function includes a three-roll mill, a mounting frame at the front end of the three-roll mill, a filter screen on the inner side of the mounting frame, a pull-out assembly on one side of the filter screen, a material slide plate below the filter screen, the material slide plate being fixedly connected to the mounting frame, and multiple elastic rods below the material slide plate, with gravity balls fixedly connected to the outer sides of each of the multiple elastic rods.

[0007] Preferably, the pull-out assembly includes a fixing block, which is fixedly connected to the filter screen. A vertical rod is rotatably connected to the upper end of the fixing block, and a connecting rod is rotatably connected to the upper end of the vertical rod. A connecting block is rotatably connected to the lower end of the connecting rod, and an eccentric disk is fixedly connected to the lower end of the connecting block. A dual-axis motor is fixedly installed on the inner side of the mounting frame, and the eccentric disk is fixedly connected to the upper output end of the dual-axis motor.

[0008] Preferably, the lower output end of the dual-axis motor is connected to a transmission assembly, the transmission assembly includes a rotating shaft, the rotating shaft is rotatably connected to the mounting bracket, and the plurality of elastic rods are fixedly connected to the rotating shaft.

[0009] Preferably, the transmission assembly further includes a round rod, the upper end of which is fixedly connected to the lower output end of the dual-axis motor, the lower end of which is fixedly connected to a main conical wheel, a driven conical wheel meshing with the outer side of the main conical wheel, and the rotating shaft being fixedly connected to the driven conical wheel.

[0010] Preferably, four springs are fixedly connected to the outer side of the filter screen, and the other end of each of the four springs is fixedly connected to the mounting bracket.

[0011] Preferably, the front end of the three-roll mill is fixedly connected to a discharge plate, and the front end of the discharge plate is located above the filter screen.

[0012] Preferably, the front end of the mounting frame is provided with a collection box, and the upper end of the collection box is slightly lower than the lower end of the material slide plate.

[0013] Compared with the prior art, this utility model has the following beneficial effects: This three-roll mill with screening function drives the eccentric disk to rotate through the upper output end of the dual-shaft motor, thereby enabling the connecting block to move the connecting rod, which in turn enables the upright rod to pull the fixed block to move. With the cooperation of springs, the filter screen can swing back and forth inside the mounting frame, which can easily screen the material in the filter screen. The lower output end of the dual-shaft motor drives the round rod to rotate, and with the cooperation of the main cone wheel and the driven cone wheel, the rotating shaft can rotate inside the mounting frame. This enables multiple elastic rods to drive gravity balls to knock on the material slide plate, promoting the material at the top of the material slide plate to slide quickly into the inner cavity of the collection box for collection, preventing the material from accumulating at the top of the material slide plate. The effect is better than the traditional method. Attached Figure Description

[0022] In this embodiment, the pull-out assembly 4 includes a fixing block 45, which is fixedly connected to the filter screen 3. The upper end of the fixing block 45 is rotatably connected to a vertical rod 44, the upper end of the vertical rod 44 is rotatably connected to a connecting rod 43, the lower end of the connecting rod 43 is rotatably connected to a connecting block 42, and the lower end of the connecting block 42 is fixedly connected to an eccentric disk 41. A dual-axis motor 5 is fixedly installed on the inner side of the mounting bracket 2, and the eccentric disk 41 is fixedly connected to the upper output end of the dual-axis motor 5.

[0023] Specifically, the upper output end of the dual-axis motor 5 drives the eccentric disk 41 to rotate. The rotation of the eccentric disk 41 drives the connecting block 42 to rotate. The rotation of the connecting block 42 drives the connecting rod 43 to move, thereby enabling the upright rod 44 to pull the fixed block 45 to move. This, in turn, causes the filter screen 3 to swing back and forth inside the mounting frame 2, which can easily screen the material in the filter screen 3. The screened material will fall onto the upper end of the material slide plate 7.

[0024] In this embodiment, the lower output end of the dual-axis motor 5 is connected to a transmission assembly 6. The transmission assembly 6 includes a rotating shaft 64, which is rotatably connected to the mounting bracket 2. Multiple elastic rods 11 are fixedly connected to the rotating shaft 64. The transmission assembly 6 also includes a round rod 61, the upper end of which is fixedly connected to the lower output end of the dual-axis motor 5. The lower end of the round rod 61 is fixedly connected to a main conical wheel 62. A driven conical wheel 63 meshes with the outer side of the main conical wheel 62. The rotating shaft 64 is fixedly connected to the driven conical wheel 63.

[0025] Specifically, the lower output end of the dual-axis motor 5 drives the round rod 61 to rotate, the rotation of the round rod 61 drives the main cone wheel 62 to rotate, and the rotation of the main cone wheel 62 drives the driven cone wheel 63, which meshes with the main cone wheel 62, to rotate, thereby realizing the rotation of the rotating shaft 64 inside the mounting bracket 2.

[0026] In this embodiment, four springs 9 are fixedly connected to the outer side of the filter screen 3, and the other end of each of the four springs 9 is fixedly connected to the mounting bracket 2.

[0027] Specifically, the design of spring 9 allows the filter screen 3 to vibrate back and forth inside the mounting frame 2.

[0028] In this embodiment, a discharge plate 10 is fixedly connected to the front end of the three-roll mill 1, and the front end of the discharge plate 10 is located above the filter screen 3.

[0029] Specifically, the outlet of the discharge plate 10 is located above the filter screen 3, allowing materials to fall conveniently into the filter screen 3.

[0030] In this embodiment, a collection box 8 is provided at the front end of the mounting frame 2, and the upper end of the collection box 8 is slightly lower than the lower end of the material slide plate 7.

[0031] Specifically, the design of collection box 8 allows for convenient collection of materials.

[0032] It should be noted that this utility model is a three-roll mill with a screening function. The user grinds the material through the three-roll mill 1. The ground material flows through the discharge plate 10 into the upper end of the filter screen 3. At this time, the dual-shaft motor 5 is started. The upper output end of the dual-shaft motor 5 drives the eccentric disk 41 to rotate. The rotation of the eccentric disk 41 drives the connecting block 42 to rotate. The rotation of the connecting block 42 drives the connecting rod 43 to move, thereby realizing that the upright 44 pulls the fixed block 45 to move. With the cooperation of the spring 9, the filter screen 3 can swing back and forth inside the mounting frame 2, which can conveniently filter the material in the filter screen 3. The material is screened and falls onto the upper part of the material slide plate 7. When the dual-axis motor 5 starts, the lower output end of the dual-axis motor 5 drives the round rod 61 to rotate. The rotation of the round rod 61 drives the main cone wheel 62 to rotate. The rotation of the main cone wheel 62 drives the driven cone wheel 63, which meshes with the main cone wheel 62, to rotate. This causes the rotating shaft 64 to rotate inside the mounting frame 2, thereby causing multiple elastic rods 11 to rotate. The rotation of multiple elastic rods 11 drives multiple gravity balls 12 to knock on the material slide plate 7, promoting the material at the upper part of the material slide plate 7 to slide quickly into the inner cavity of the collection box 8, preventing the material from accumulating at the upper part of the material slide plate 7. This is quite practical.

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.
