In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The current open mixing mill requires manual shoveling and turning of materials when preparing thermal conductive materials, and the resulting products are not highly consistent and are difficult to meet customer needs.

[0036] The present application intends to provide an open refining device, which can reduce manual involvement and make the consistency of the produced products higher.

[0037] Figure 1 A schematic diagram of the structure of the device provided in the embodiment of the present application, such as Figure 1 As shown, an embodiment of the present application provides an open refining device, and the open refining device 1000 includes: a frame 100, an open refining unit 200, a material shoveling unit 300, a material receiving and turning unit 400 and a control unit.

[0038] The frame 100 is installed on the working platform. Usually, the frame 100 is U-shaped (or forms a U-shape together with the working platform), and the notch is used to install the open refining unit 200.

[0039] The open refining unit 200 is used to perform open refining treatment on the material to be refined; the open refining unit 200 includes a pair of open refining rollers 210, and the open refining rollers 210 are installed on the frame 100. Usually, the pair of open refining rollers 210 rotate in opposite directions, and their driving devices can usually be selected from motors, etc. Generally speaking, components such as reducers are also arranged between the open refining rollers 210 and their driving devices, which will not be described in detail here.

[0040] Among them, the shoveling unit 300 is used to separate the material from the refining roller 210 during the refining process; the shoveling unit 300 is installed on the frame 100, and the shoveling unit 300 includes a scraper 310, one end of which is in contact with the refining roller 210 to scoop the material on the refining roller 210.

[0041] It should be noted that during the refining process, the material usually only adheres to one of the refining rollers 210, so only one shoveling unit 300 is required. If some materials or some refining equipment cannot achieve the material adhering to only one refining roller 210, then one shoveling unit 300 can be respectively provided on the two refining rollers 210.

[0042] In some embodiments, the scraper 310 is installed on the frame 100 so as to be movable along the axis direction of the open refining roller 210, and the length of the scraper 310 is less than the length of the open refining roller 210. The displacement path of the scraper 310 at least covers the adhesion area of ​​the material on the open refining roller 210, and the displacement path is usually equivalent to the length of the open refining roller 210. By making the scraper 310 movable along the axis direction of the open refining roller 210, the scraper 310 cuts off the material on the open refining roller 210 at different positions, which is more conducive to the open refining process of the material.

[0043] In some embodiments, the method for moving the scraper 310 along the axis direction of the open refining roller 210 can be: the scraper unit 300 also includes a first driving mechanism 320, the first driving mechanism 320 includes a screw nut 321, a guide rod 322 and a first driving member 323, the screw of the screw nut 321 is rotatably mounted on the frame 100, the screw and the open refining roller 210 are arranged in parallel, the scraper 310 is mounted on the nut of the screw nut 321, the guide rod 322 is mounted on the frame 100 and arranged in parallel with the screw, the nut is provided with a guide hole (not shown in the figure), the guide rod 322 is penetrated in the guide hole, the first driving member 323 is mounted on the frame 100, and the output end of the first driving member 323 is transmission-connected with the screw. The first driving member 323 can be specifically selected from a servo motor. The first driving member 323 drives the screw rod to rotate back and forth, so that the nut can reciprocate on the screw rod, thereby driving the scraper 310 to reciprocate on the side wall of the open refining roller 210 along the axial direction of the open refining roller 210 .

[0044] Among them, the material receiving and turning unit 400 is used to realize the turning of materials during the refining process; the material receiving and turning unit 400 is installed on the frame 100, and the material receiving and turning unit 400 includes a material receiving and turning bucket 410, and the material receiving and turning bucket 410 can be installed on the frame 100 rotatably around the refining roller 210, so that the material receiving and turning bucket 410 receives the material scooped by the scraper 310 at the material receiving station, and turns it to the feeding station to feed the material to the refining roller 210. The material receiving station is usually set at the lower end of the refining roller 210, and the material falls into the material receiving station due to gravity. The feeding station is usually set at the upper end of the refining roller 210, connected with the feeding channel of the refining roller 210, and the material falls onto the refining roller 210 due to gravity.

[0045] In this embodiment, the shape of the material receiving tipping bucket 410 is not limited, and can be an elliptical cylinder, a cube, etc. Its open end is usually larger than the area corresponding to the refining roller 210 so as to fully receive the material, and the open end is usually larger than its lower end so as to pour out the material.

[0046] In some embodiments, the material receiving and flipping unit 400 includes a second driving mechanism 420, which includes a pair of rails 421, a pair of moving parts 422 and a second driving member 423. The pair of rails 421 are relatively installed on the frame 100, and the two moving parts 422 are respectively installed on the two rails 421, and the moving parts 422 can move along the rails 421. The output end of the second driving member 423 is connected to the moving part 422 by transmission, and the material receiving and flipping bucket 410 is connected to the moving part 422 to drive the material receiving and flipping bucket 410 to switch between the material receiving station and the feeding station. The second driving member 423 can be specifically selected from a servo motor. The second driving member 423 drives the moving part 422 to move on the rail 421, thereby driving the material receiving and flipping bucket 410 to move along the rail 421, so as to realize the switching of the material receiving and flipping bucket 410 between the material receiving station and the feeding station.

[0047] In some embodiments, the track 421 is a circular track 421, and the open refining roller 210 is disposed in the circular track 421. The circular track 421 is used as the track 421, and the open refining roller 210 is disposed in the circular track 421. When the material receiving and turning bucket 410 moves along the circular track 421, the switching between the material receiving station and the material feeding station is naturally realized.

[0048] It should be noted that the annular track 421 may be a circular track 421 , an elliptical track 421 , etc. The open refining roller 210 is disposed in the annular track 421 , which means that the open refining roller 210 is located in the annular track 421 from the perspective of the extending direction of the open refining roller 210 .

[0049] In some embodiments, a limit switch 424 is provided in the annular track 421, and the limit switch 424 is connected to the second driving member 423 by signal, so as to control the start and stop of the second driving member 423 to realize the switching between the receiving station and the feeding station. By setting the limit switch 424, the movement path of the material transfer bucket 410 is restricted, so as to accurately realize the receiving and feeding of materials.

[0050] It is understandable that in other embodiments, only the section of the annular track 421 where the limit switch 424 is provided may be cut off as the track 421, and both ends may be closed to further reduce the material usage of the device, thereby helping to reduce the cost of the device.

[0051] In some embodiments, the moving member 422 is a gear, and a rack meshing with the gear is provided in the track 421. It is understandable that in other embodiments, the movement of the moving member 422 in the track 421 may be achieved without the cooperation of the gear and the rack. For example, a large friction force between the moving member 422 and the track 421 may also be used to achieve the movement of the moving member 422 in the track 421.

[0052] Figure 2 The structural diagram of the material receiving and turning unit provided in the embodiment of the present application is as follows: Figure 2 As shown, in some embodiments, the second driving member 423 is a double-shaft motor, and the two output shafts of the double-shaft motor are respectively connected to the moving member 422. The material receiving and turning bucket 410 is hinged to the double-shaft motor through a connecting rod 425. The material receiving and turning bucket 410 is provided with at least two limiting posts 426, and the two limiting posts 426 are respectively provided on both sides of the connecting rod 425 to cooperate with the connecting rod 425 to limit the position of the material receiving and turning bucket 410. By hingedly connecting the material receiving and turning bucket 410 to the two output shafts, it is easier to feed materials at the feeding station. At the same time, the material receiving and turning bucket 410 is provided with limiting posts 426, which can prevent the material receiving and turning bucket 410 from being excessively tilted and falling materials before reaching the feeding station, thereby effectively reducing the loss of materials.

[0053] It should be noted that, since the motor housing is heavy and the speed of driving the material receiving and tipping bucket 410 is slow (i.e., the output shaft has a slow rotation speed), after the second driving member 423 is started, basically only the moving member 422 moves along the track 421, and the motor housing will not rotate. Of course, in other embodiments, a limit groove can be provided on the track 421, and a limit rod can be connected to the motor housing, and the limit rod cooperates with the limit groove to limit the rotation of the housing.

[0054] Among them, the control unit is respectively connected to the open refining unit 200, the shoveling unit 300 and the receiving and turning unit 400 by signal, so as to control the start and stop of the open refining unit 200, the shoveling unit 300 and the receiving and turning unit 400. Through the setting of the control unit, the automatic start and stop of the open refining unit 200, the shoveling unit 300 and the receiving and turning unit 400 in the open refining equipment can be realized, which further reduces the manual participation and is more conducive to the uniformity of the product. Specifically, the control unit is respectively electrically connected to the driving mechanism in the open refining unit 200, the shoveling unit 300 and the receiving and turning unit 400, such as the first driving member 323, the second driving member 423, etc. The control unit can specifically adopt a PLC control unit.

[0055] In some embodiments, the device further comprises a plurality of baffle plates 500, which are mounted on the frame 100 and are located above the open refining roller 210. The plurality of baffle plates 500 enclose a feeding channel. By providing a plurality of baffle plates 500 and enclosing them to form a feeding channel, the feeding accuracy can be effectively improved and the loss of materials can be further reduced.

[0056] Usually, there are four guide plates, two of which are disposed on both sides of the open refining roller 210 , and the other two are disposed on both ends of the open refining roller 210 .

[0057] The implementation process of the entire device is as follows: the material to be refined is put into the refining unit 200 for refining treatment, and then the shoveling unit 300 is started, and the scraper 310 moves on the refining roller 210 to shovel the material from the refining roller 210, and the material falls into the material receiving and turning bucket 410, and the second driving mechanism 420 of the material receiving and turning unit 400 is started, and the material receiving and turning bucket 410 is moved from the material receiving station to the material feeding station to realize the turning of the material, and then moved from the material feeding station to the material receiving station, and the refining treatment, material shoveling and material receiving and turning are repeated until the preparation is completed.

[0058] The device can realize automatic material shoveling and automatic material turning by setting the material shoveling unit 300 and the material receiving and turning unit 400, avoiding the unstable factors of manual labor, effectively improving the consistency of products, and at the same time reducing the labor intensity, reducing the labor cost, and improving the efficiency of the mill.

[0059] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0060] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
