DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application.

[0031] Examples of the described embodiments are shown in the drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are intended to explain the application, and cannot be understood as a limitation of the application.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: See Figures 1-3 The present invention provides a technical solution: a colloid mill for producing an antibacterial preparation of oral ulcer gel, comprising a cooling mechanism 1, the cooling mechanism 1 including a support frame 101, a fixing frame 103 fixedly sleeved on the outer surface of the support frame 101, a support foot 104 fixedly connected to the outer wall of the fixing frame 103 away from the support frame 101, and a groove 102 formed on the top outer surface of the support frame 101, and further comprising:

[0034] The grinding mechanism 2 includes a motor 201 fixedly connected to a support frame 101. The top output end of the motor 201 passes through the support frame 101 and is fixedly connected to a rotating shaft 202. A fixing block 208 is fixedly sleeved on the outer surface of the rotating shaft 202. A fan 203 is fixedly connected to the bottom output end of the motor 201. A second connecting frame 209 is fixedly sleeved on the outer surface of the rotating shaft 202. A grinding block 210 is fixedly connected to the end of the second connecting frame 209 away from the rotating shaft 202. A first protrusion 211 is fixedly connected to the top outer wall of the second connecting frame 209. An auxiliary component 212 is provided on the top of the grinding block 210. In the operation of grinding the oral ulcer gel antibacterial preparation colloid, the colloid is first... The solution is injected from the top of the support frame 101 into the interior of the support frame 101. Then, the motor 201 is started, and the fan 203, which is fixedly connected to the bottom output end of the motor 201, starts to rotate. When the fan 203 rotates, it will accelerate the flow of the surrounding air. The air carries away the heat from the bottom of the support frame 101, thereby achieving a cooling effect on the bottom of the support frame 101 and avoiding adverse effects on the properties of the colloid due to excessive temperature during the grinding process. The rotation of the motor 201 is transmitted to the second connecting frame 209 through the rotating shaft 202, which drives the second connecting frame 209 to rotate. The grinding block 210 fixed on the second connecting frame 209 also rotates accordingly. The rotating grinding block 210 grinds the oral ulcer gel antibacterial preparation colloid.

[0035] The support frame 101 has a through hole 108 on its bottom inner wall and a collection groove 109 at its bottom. A discharge pipe 107 is fixedly connected to the outer wall of the support frame 101 near the collection groove 109. The through hole 108 is used to filter larger gel colloidal particles. A cooling groove 105 is provided on the inner wall of the support frame 101. A water inlet pipe 106 is fixedly connected to the outer wall of the support frame 101, and a water outlet pipe 110 is fixedly connected to the outer wall of the support frame 101 away from the water inlet pipe 106. This cooling groove is used to reduce the amount of oral ulcer gel antibacterial material being ground. When the formulation colloid temperature is reached, the water inlet pipe 106 introduces cooling water into the cooling tank 105 of the support frame 101. As the cooling water is continuously injected, the cooling tank 105 is gradually filled with coolant. At this time, the coolant exchanges heat with the colloid being ground, absorbing the heat of the colloid, thereby achieving the cooling effect on the colloid. Afterward, the cooled coolant is discharged from the cooling tank 105 through the water outlet pipe 110. The ground oral ulcer gel antibacterial formulation colloid is filtered and discharged from the discharge pipe 107.

[0036] Example 2: Please refer to Figures 4-8 Based on Embodiment 1, the present invention provides a technical solution: A first connecting frame 204 is fixedly connected to the inner wall of the end of the rotating shaft 202 away from the motor 201. An auxiliary wheel 205 is rotatably connected to the outer wall of the end of the first connecting frame 204 near the support frame 101 via a rotating shaft. When the motor 201 is running, its rotating shaft 202 rotates accordingly and transmits the rotational power to the first connecting frame 204, so that the first connecting frame 204 obtains power and slides along the top outer wall of the support frame 101. During the sliding process of the first connecting frame 204, the auxiliary wheel 205 installed thereon contacts the groove 102 on the top outer wall of the support frame 101. Since the groove 102 has a restrictive and guiding effect on the auxiliary wheel 205, the auxiliary wheel 205 can only roll on the inner wall of the groove 102. This rolling contact method transforms the sliding friction between the first connecting frame 204 and the groove 102 into rolling friction, which greatly reduces the friction force and reduces the shaking and instability factors of the first connecting frame 204 during the sliding process, thereby enhancing the stability of the first connecting frame 204 during the rotation process.

[0037] A first stirring blade 206 is fixedly connected to the inner wall of the first connecting frame 204. An inclined plate 207 is fixedly connected to the inner wall of the first connecting frame 204 away from the first stirring blade 206. When the oral ulcer gel antibacterial preparation is being fed, the first stirring blade 206 stirs the oral ulcer gel antibacterial preparation as the first connecting frame 204 rotates. The inclined plate 207 is set in a circular funnel shape, which can improve the feeding speed of the oral ulcer gel antibacterial preparation.

[0038] The auxiliary component 212 includes a first rotating rod 2121 rotatably connected to a fixed block 208. A second rotating rod 2122 is rotatably connected to the end of the first rotating rod 2121 away from the fixed block 208 via a rotating shaft. A sliding frame 2123 is provided at the end of the second rotating rod 2122 away from the first rotating rod 2121. A first spring 2124 is fixedly connected to the outer wall of the sliding frame 2123 near the rotating shaft 202. The end of the first spring 2124 away from the sliding frame 2123 is fixedly connected to the rotating shaft 202. The inner wall of the sliding frame 2123 is rotatably connected to the second rotating rod 2122 via a rotating shaft. A second protrusion 2129 is fixedly connected to the bottom of the sliding frame 2123. The motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 rotates rapidly, generating centrifugal force. Under the action of centrifugal force, the sliding frame 2123 is pushed outward and begins to move towards the edge of the support frame 101. During this process, the first spring 2124 connecting the sliding frame 2123 is stretched. The first spring 2124 stores elastic potential energy. When the sliding frame 2123 moves, the second protrusion 2129 at its bottom will meet the first protrusion 211 on the support frame 101. Due to the contact and collision between the two, the sliding frame 2123 is subjected to an impact force instantaneously, thereby generating vibration. This vibration will be transmitted to the components associated with the sliding frame 2123 or the material it carries, which may play a role such as preventing material agglomeration and promoting uniform mixing of materials.

[0039] An auxiliary rod 2125 is rotatably connected to the inner wall of the sliding frame 2123 via a rotating shaft. A scraper 2126 is rotatably connected to the end of the auxiliary rod 2125 away from the sliding frame 2123 via a rotating shaft. The scraper 2126 is slidably connected to the inner wall of the support frame 101. A second stirring blade 2128 is fixedly connected to the outer wall of the auxiliary rod 2125, and a second spring 2127 is fixedly connected to the inner wall of the auxiliary rod 2125. The motor 201 drives the rotating shaft 202 to rotate, causing the sliding frame 2123 connected to it to rotate as well. Since the sliding frame 2123 and the scraper 2126 are connected via the auxiliary rod 2125... 5. During rotation, the sliding frame 2123 pushes the scraper 2126 towards both sides of the inner wall of the support frame 101 with the help of the auxiliary rod 2125. During the movement, the scraper 2126 comes into contact with the oral ulcer gel adhering to the inner wall of the support frame 101. The friction between the scraper 2126 and the gel scrapes off the gel adhering to the inner wall of the support frame 101, thereby cleaning the inner wall of the support frame 101. As the auxiliary rod 2125 rotates with the rotating shaft 202, the second stirring blade 2128 fixedly connected to the outer wall of the auxiliary rod 2125 stirs the oral ulcer gel.
