Description

Technical Field

[0001] This utility model relates to the field of vacuum mixer technology, specifically a thermally conductive silicone vacuum mixer. Background Technology

[0002] In the production process of thermal conductive silicone, silicone oil and alumina powder are usually mixed evenly and then heated and dried. The uniformity of the mixing of silicone oil and alumina powder directly affects the quality of the product. Therefore, the stirring during the processing of thermal conductive silicone is particularly important.

[0003] In traditional mixers, raw materials often migrate outwards during the mixing process, and may even adhere firmly to the inner wall of the mixing drum in the later stages. While using a mixing rod equipped with a wall scraper can clean the adhering material, it generates significant operating resistance and accelerates wear on the inner wall of the mixing drum, significantly shortening its service life. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A thermally conductive silicone vacuum mixer includes a mixing mechanism and an internal scraper mechanism. The mixing mechanism includes a base, a container inserted into the top of the base, a mixing rod rotatably installed inside the container, and a motor connected between the container and the mixing rod. The internal scraper mechanism includes a canopy fixed to the top of the base, a U-shaped plate connected to the top of the canopy's inner cavity, a bidirectional electric push rod extending transversely through the U-shaped plate, two arc plates respectively connected to the two movable ends of the bidirectional electric push rod, a tactile switch fixed to the bottom of the U-shaped plate, and inclined surfaces on both sides of the arc plates. The tactile switch is electrically connected to the bidirectional electric push rod.

[0007] By adopting the above technical solution, silicone oil and alumina powder are placed in the container, and then the motor and stirring rod work together to stir the raw materials. During this process, two bidirectional electric push rods extend and retract synchronously at timed intervals, and then the container moves up and down repeatedly. Two arc plates scrape off the raw materials adhering to the inner wall of the container. Then, the top of the stirring rod presses against the touch switch, and accordingly, the bidirectional electric push rod retracts the two arc plates. The arc plates push the raw materials on the inner wall of the container toward the stirring rod, thus ensuring the stirring efficiency without increasing power consumption.

[0008] In a preferred embodiment, the present invention can be further configured such that: a sleeve is fitted onto the outer side of the motor body, and the sleeve is fixedly connected to the inside of the base.

[0009] In a preferred embodiment, the present invention can be further configured such that: the canopy is composed of a hollow cylinder and multiple support rods, with the multiple support rods arranged in pairs, forming two groups, and the two groups of support rods are respectively fixed to both sides of the hollow cylinder.

[0010] In a preferred embodiment, this utility model can be further configured as follows: two arc plates are symmetrically arranged and fit together, the two arc plates are spliced ​​to form a hollow column, the hollow column is coaxial with the container vertically, the diameter of the hollow column is equal to the inner diameter of the container, and the inner edge of the bottom end of the arc plate is arc-shaped.

[0011] In a preferred embodiment, the present invention can be further configured such that: a vacuum assembly is provided on the top of the base, the vacuum assembly including a sealing cover that is slidably sleeved on the outside of the empty cylinder, a rubber ring that is movably sleeved on the bottom of the sealing cover and fixed to the top of the base, and a vacuum pump that is connected and communicates with the sealing cover.

[0012] In a preferred embodiment, the present invention can be further configured such that a handle is fixedly attached to the front side of the sealing cover, and the handle is located at the bottom of the vacuum pump.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, silicone oil and alumina powder are placed in a container, and then a motor and a stirring rod work together to stir the raw materials. During this process, two bidirectional electric push rods extend and retract synchronously at timed intervals, and then the container moves up and down repeatedly. Two arc plates scrape off the raw materials adhering to the inner wall of the container. Then, the top of the stirring rod presses against a touch switch, and correspondingly, the bidirectional electric push rod retracts the two arc plates. The arc plates push the raw materials on the inner wall of the container toward the stirring rod, thereby ensuring stirring efficiency without increasing power consumption.

[0015] 2. In this utility model, after the sealing cover and rubber ring are closed, the vacuum pump is started, and then the roof and sealing cover cooperate to provide a vacuum stirring environment for the container, which effectively ensures the material forming effect.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a thermally conductive silicone vacuum mixer.

[0030] Example 1:

[0031] Combination Figure 1-7 As shown, the present invention provides a thermally conductive silicone vacuum mixer, which includes a mixing mechanism 100 and an inner scraper mechanism 200. The mixing mechanism 100 includes a base 110, a container 120 inserted into the top of the base 110, a stirring rod 130 rotatably installed inside the container 120, and a motor 140 connected between the container 120 and the stirring rod 130.

[0032] The internal raking mechanism 200 includes a canopy 210 fixedly connected to the top of the base 110, a U-shaped plate 220 connected to the top of the inner cavity of the canopy 210, a bidirectional electric push rod 230 extending transversely through the U-shaped plate 220, two arc plates 240 respectively connected to the two movable ends of the bidirectional electric push rod 230, a tactile switch 250 fixedly connected to the bottom of the U-shaped plate 220, and inclined surfaces 260 provided on both sides of the arc plates 240. The tactile switch 250 is electrically connected to the bidirectional electric push rod 230.

[0033] Furthermore, the canopy 210 is composed of a hollow cylinder and multiple support rods. The multiple support rods are arranged in pairs, forming two groups. The two groups of support rods are respectively fixed to both sides of the hollow cylinder. The structural design of the canopy 210 allows it to stand firmly on the top of the container 120.

[0034] Furthermore, the two arc plates 240 are symmetrically arranged and fit together, and the two arc plates 240 are spliced ​​to form a hollow column. The hollow column is vertically coaxial with the container 120, and the diameter of the hollow column is equal to the inner diameter of the container 120. The inner edge of the bottom of the arc plate 240 is arc-shaped. The size design of the two arc plates 240 allows the arc plates 240 to smoothly scrape the raw material from the inner wall of the container 120.

[0035] Example 2:

[0036] Combination Figure 3 As shown, based on Embodiment 1, a sleeve is fitted on the outer side of the motor 140 body. The sleeve is fixed inside the base 110. The sleeve can reinforce the motor 140, so that it can smoothly drive the stirring rod 130 to rotate.

[0037] Example 3:

[0038] Combination Figure 1 , 2 and Figure 7 As shown, in the above embodiment, the base 110 is provided with a vacuum assembly 300 on top. The vacuum assembly 300 includes a sealing cover 310 that is slidably sleeved on the outside of the empty cylinder, a rubber ring 320 that is movably sleeved on the bottom of the sealing cover 310 and fixed to the top of the base 110, and a vacuum pump 330 that is connected and communicates with the sealing cover 310. After the sealing cover 310 and the rubber ring 320 are closed, the vacuum pump 330 is started. Then, the top 210 and the sealing cover 310 cooperate to provide a vacuum stirring environment for the container 120, which effectively ensures the material forming effect.

[0039] Furthermore, a handle is fixed to the front side of the sealing cover 310. The handle is located at the bottom of the vacuum pump 330 and is provided to facilitate the user to lift the sealing cover 310.

[0040] The working principle and usage process of this utility model are as follows: Silicone oil and alumina powder are placed in the container 120. Then, the motor 140 and the stirring rod 130 work together to stir the raw materials. During this process, the two bidirectional electric push rods 230 extend and retract synchronously at timed intervals. Then, the container 120 reciprocates up and down. The two arc plates 240 scrape off the raw materials adhering to the inner wall of the container 120. Then, the top of the stirring rod 130 presses against the touch switch 250. Correspondingly, the bidirectional electric push rod 230 retracts the two arc plates 240. The arc plates 240 push the raw materials on the inner wall of the container 120 toward the stirring rod 130. Thus, the stirring efficiency is guaranteed without increasing power consumption.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
