The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0045] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0046] Reference Figure 6 , Figure 7 As shown, during the production of silicone oil, a stirring rod 620 is used to mix the raw materials. To improve the mixing effect and efficiency, some stirring rods 620 are equipped with external features. Figure 7The spiral stirring ring shown is provided with both an inner spiral stirring ring 622 and an outer spiral stirring ring 621. The spiral stirring ring improves the stirring effect, but it also has the problem of its surface being difficult to clean. In addition, the surface of the spiral stirring ring used for stirring silicone oil usually needs to be polished and cleaned, which further increases the cleaning difficulty. For non-spiral stirring rings, manual access through the inspection hole at the top of the vessel 600 allows for grinding and cleaning within the vessel's cavity 610. However, the spiral stirring ring, due to its continuous structure, leaves only a narrow space between its outer wall and the inner wall of the vessel's cavity 610, making manual access impossible. Consequently, the top cover of the vessel 600 often needs to be opened, and the stirring rod 620 completely lifted out for grinding and cleaning. This process typically requires manual work, resulting in low efficiency, high labor costs, and significant time consumption, impacting silicone oil production efficiency. Furthermore, frequent disassembly of the top cover of the vessel 600 and lifting of the stirring rod 620 may affect the seal between the cover and the vessel 600, and between the cover and the stirring rod 620.

[0047] To address the aforementioned technical problems, the first aspect of this utility model discloses a grinding device for a stirring rod 620. This device can extend from the inspection hole of the top cover plate of the vessel body 600 into the cavity 610 of the vessel body 600 to grind and clean the spiral stirring ring. This eliminates the need to open the cover plate and lift out the stirring rod 620, thereby improving grinding and cleaning efficiency, reducing labor costs, increasing the production efficiency of silicone oil, and reducing equipment wear caused by frequent cover opening and lifting of the stirring rod 620.

[0048] Reference Figures 1 to 5 The stirring rod 620 polishing device of this application embodiment includes a base frame 100, a vertical plate 200, a support 300, a first driving structure 400, and a clamping structure 500. The base frame 100 can be installed on the vessel body 600 or not. The vertical plate 200 is movably and vertically installed on the base frame 100. The support 300 is hinged to the vertical plate 200. The first driving structure 400 is installed on the support 300. The clamping structure 500 is connected to the output end of the first driving structure 400. The first driving structure 400 is used to drive the clamping structure 500 to rotate around the axis. The clamping structure 500 includes a first clamping plate 510 and a second clamping plate 520 that can move relative to each other. A polishing layer 530 is installed on the opposite side of the first clamping plate 510 and the second clamping plate 520. The clamping structure 500 has a first position and a second position. The support 300 rotates around the hinge with the upright plate 200 to drive the clamping structure 500 to switch between the first position and the second position. When the clamping structure 500 is in the first position, it is folded into the upright plate 200. When the clamping structure 500 is in the second position, it is perpendicular to the upright plate 200.

[0049] The process of using the polishing device in this embodiment includes the following steps:

[0050] 1. Open the inspection hole of the vessel body 600 and place the base frame 100 above the inspection hole. At this time, the clamping structure 500 is in the first position.

[0051] 2. The drive plate 200 descends relative to the base frame 100, causing the support 300, the first drive structure 400 and the clamping structure 500 to enter the cavity 610 of the vessel body 600;

[0052] 3. When the clamping structure 500 descends to the first set height, the support 300 rotates around the hinge with the upright plate 200 to drive the clamping structure 500 to switch from the first position to the second position.

[0053] 4. The first driving structure 400 drives the clamping structure 500 to rotate axially at a set angle to match the spiral angle of the spiral stirring ring;

[0054] 5. The first clamping plate 510 and the second clamping plate 520 slide in opposite directions to increase the distance between the first clamping plate 510 and the second clamping plate 520.

[0055] 6. Rotate the stirring rod 620. When it is confirmed that the spiral stirring ring has entered between the first clamping plate 510 and the second clamping plate 520, the first clamping plate 510 and the second clamping plate 520 slide towards each other to clamp the spiral stirring ring. The grinding layer 530 installed on the first clamping plate 510 and the second clamping plate 520 grinds and cleans the spiral stirring ring.

[0056] 7. During the rotation of the stirring rod 620, the clamping structure 500 will gradually descend due to the rotation of the spiral stirring ring; when the clamping structure 500 descends to the second set height, the first clamping plate 510 and the second clamping plate 520 slide in opposite directions to increase the distance between the first clamping plate 510 and the second clamping plate 520, and the stirring rod 620 reverses.

[0057] 8. During the reverse rotation of the stirring rod 620, the clamping structure 500 gradually rises to the first set height;

[0058] 9. Repeat steps 5 to 8 as many times as set, and then run steps 1 to 4 in reverse order to complete the grinding of the spiral stirring ring.

[0059] As can be seen from the above polishing process, the polishing device of this embodiment can polish and clean the spiral stirring ring of the stirring rod 620 without lifting the stirring rod 620 out, which greatly improves the cleaning efficiency, reduces manual labor, and lowers maintenance costs and silicone oil production costs.

[0060] Reference Figure 1As shown, to facilitate cleaning of the outer wall of the spiral stirring ring, in this embodiment, the first clamping plate 510 has a first protrusion 511 protruding from one side of its surface facing the second clamping plate 520, and the second clamping plate 520 has a second protrusion 521 protruding from its surface on the side facing the first clamping plate 510. The first protrusion 511 and the second protrusion 521 are correspondingly arranged. A polishing layer 530 is installed on the side of the first protrusion 511 and the second protrusion 521 away from the first drive structure 400. The polishing layer 530 is preferably detachably connected to the first clamping plate 510, the second clamping plate 520, and the second protrusion 521 for easy replacement. The polishing layer 530 can be made of sandpaper or the like. The first protrusion 511 is preferably detachably connected to the first clamping plate 510, and the second protrusion 521 is preferably detachably connected to the second clamping plate 520, so that the first protrusion 511 and the second protrusion 521 can be replaced individually, reducing maintenance costs.

[0061] In the embodiments of this application, the first protrusion 511 is disposed at one end of the first clamping plate 510 near the first driving structure 400, and the second protrusion 521 is disposed at one end of the second clamping plate 520 near the first driving structure 400. The first protrusion 511 and the second protrusion 521 cooperate to polish and clean the outer wall of the outer spiral stirring ring 621.

[0062] Furthermore, referring to Figure 7 As shown, since the stirring rod 620 is provided with an outer spiral stirring ring 621 and an inner spiral stirring ring 622 on its outer periphery, in order to facilitate the simultaneous cleaning of the outer side wall of the inner spiral stirring ring 622, the first clamping plate 510 of this embodiment can refer to... Figure 1 Two first protrusions 511 are provided, one in the middle of the first clamping plate 510 and the other at the end of the first clamping plate 510 near the first drive structure 400. Two second protrusions 521 are provided corresponding to the first protrusions 511, with each second protrusion 521 corresponding to one of the first protrusions 511. The first protrusions 511 at the end of the first clamping plate 510 and the second protrusions 521 at the end of the second clamping plate 520 are used to polish the outer wall of the outer spiral stirring ring 621, while the first protrusions 511 in the middle of the first clamping plate 510 and the second protrusions 521 in the middle of the second clamping plate 520 are used to polish the outer wall of the inner spiral stirring ring 622.

[0063] It should be noted that, referring to Figure 7As shown, since the outer spiral stirring ring 621 and the inner spiral stirring ring 622 are connected by multiple support tubes, the first protrusion 511 located in the middle of the first protrusion 511 will be obstructed by the support tubes during the rotation of the stirring rod 620. In order to avoid the support tubes damaging the first protrusion 511, the first protrusion 511 located in the middle of the first protrusion 511 and the second protrusion 521 located in the middle of the second protrusion 521 are preferably made of flexible material. The first protrusion 511 located at the end of the first clamping plate 510 and the second protrusion 521 located at the end of the second clamping plate 520 can be made of flexible material or hard material.

[0064] It is conceivable that the first clamping plate 510 could also be provided with four first protrusions 511, with two first protrusions 511 located at the ends of the first clamping plate 510, respectively used for polishing the outer and inner walls of the outer spiral stirring ring 621, and the other two first protrusions 511 located in the middle of the first clamping plate 510, respectively used for polishing the outer and inner walls of the inner spiral stirring ring 622. Correspondingly, when the first clamping plate 510 is provided with four first protrusions 511, the second clamping plate 520 is preferably provided with four second protrusions 521.

[0065] In the embodiments of this application, the thickness of the first protrusion 511 may be the same as or different from the thickness of the second protrusion 521. Preferably, the thickness of the first protrusion 511 is greater than the thickness of the second protrusion 521, or the thickness of the second protrusion 521 is greater than the thickness of the first protrusion 511. The different thicknesses of the first protrusion 511 and the second protrusion 521 can prevent the outer wall of the outer spiral stirring ring 621 from contacting the connection between the first protrusion 511 and the second protrusion 521 after the first clamping plate 510 and the second clamping plate 520 clamp the spiral stirring ring, thus affecting the grinding effect.

[0066] In the embodiments of this application, the base frame 100 is equipped with a slide rail 110 and a second drive structure 120. The upright plate 200 is movably and vertically mounted on the slide rail 110 and is connected to the second drive structure 120 for transmission. The second drive structure 120 is used to drive the upright plate 200 to move up and down along the slide rail 110. Specifically, refer to... Figure 2 , Figure 3 As shown, the base frame 100 has a slot 130 that extends axially through the base frame 100, and a slide rail 110 is located at the bottom of the slot 130. The upright plate 200 has a radially protruding first mounting seat 210. The second drive structure 120 includes a drive motor 121 and a lead screw 122. The output end of the drive motor 121 is connected to the lead screw 122. The lead screw 122 passes through the first mounting seat 210 and is connected to the first mounting seat 210 for transmission. The drive motor 121 drives the lead screw 122 to rotate around its own axis, which can drive the upright plate 200 to rise and fall. By driving the upright plate 200 to rise and fall through the lead screw 122 and the drive motor 121, it is easier to control the height of the upright plate 200 more precisely.

[0067] In the embodiments of this application, reference is made to Figure 1 , Figure 4 As shown, the drive motor 121 is mounted on the top of the base frame 100 to reduce the structure and weight of the device entering the vessel body 600 through the inspection hole, thereby improving the portability of the grinding device entering the cavity 610 of the vessel body 600 and the stability of the grinding device during use.

[0068] It is conceivable that the second drive structure 120 is not limited to using a drive motor 121 and a lead screw 122, but can also use a telescopic motor, telescopic hydraulic cylinder, telescopic pneumatic cylinder, etc., depending on the actual situation.

[0069] In the embodiments of this application, reference is made to Figure 4 , Figure 5 As shown, the upright plate 200 also has a radially protruding second mounting seat 220, and the support 300 is hinged to the second mounting seat 220; the first mounting seat 210 is disposed at the top end of the upright plate 200, and the second mounting seat 220 is disposed at the bottom end of the upright plate 200, with the first mounting seat 210 and the second mounting seat 220 protruding from both sides of the upright plate 200 in the thickness direction. The upright plate 200 is connected to the second mounting seat 220 by a pin, and the axis of the pin extends parallel to the width direction of the upright plate 200.

[0070] In the embodiments of this application, reference is made to Figure 3 , Figure 4 As shown, the base frame 100 is provided with a slot 130 that extends axially through the base frame 100. When the clamping structure 500 is in the first position, it is retracted into the slot 130 to reduce the height of the clamping structure 500 protruding from the surface of the base frame 100, thereby facilitating the grinding device of this embodiment to enter the cavity 610 of the vessel body 600 through the inspection hole.

[0071] Reference Figure 6 , Figure 7 As shown, the silicone oil mixing vessel of the second aspect embodiment of this utility model includes a vessel body 600 and a stirring rod 620. The vessel body 600 has a cavity 610, and one end of the stirring rod 620 has a spiral stirring ring, which is installed in the cavity 610. The aforementioned stirring rod 620 polishing device is installed in the vessel body 600 and can extend into the cavity 610 to polish and clean the spiral stirring ring. In this embodiment, the silicone oil mixing vessel can complete the polishing and cleaning of the stirring rod 620 with the spiral stirring ring without opening the lid, resulting in high cleaning efficiency, low cleaning cost, and reduced polishing and cleaning time, thereby improving the production efficiency of silicone oil. Since the silicone oil mixing vessel is equipped with the aforementioned polishing device, it also possesses at least all the beneficial effects of the polishing device, which will not be elaborated further here.
