Description

Technical Field

[0001] This utility model relates to the field of silicone rubber impression material production technology, specifically to a feeding device for silicone rubber impression material production. Background Technology

[0002] Silicone rubber impression materials have high precision and stability, and can accurately replicate the shape of teeth, ensuring the accuracy of restorations. The feeding device for silicone rubber impression material production can significantly improve production efficiency through automation and intelligent design.

[0003] Patent CN212736644U discloses a feeding device for the production of silicone rubber molding materials, including a base. A fixing frame is fixedly welded to the upper end of the base. A stirring tank is fixedly installed at one end of the fixing frame. A motor is fixedly installed at the bottom of the stirring tank via a fixing bracket. A rotating roller is fixedly connected to one end of the motor shaft. A second rotating bearing is embedded and fixedly installed in the top of the stirring tank. One end of the rotating roller is fixedly inserted into the inner ring of the second rotating bearing. A spiral blade is installed on the rotating roller. The rotating roller is driven by the rotation of the motor, and the rotating roller drives the spiral blade to stir the raw material particles. The stirring tank, which is connected to the heating tank, is heated by an electric heating tube set on one side of the heating tank, so that the temperature inside the stirring tank rises and heats the raw material particles. This improves to some extent the situation where it is impossible to preheat the raw material particles of silicone rubber molding materials, the raw material particles of silicone rubber molding materials melt slowly, and the production efficiency is low.

[0004] The above solution uses an electric heating element to heat the mixing tank connected to the heating tank. However, heating with an electric heating element requires a long time to reach a constant temperature, and the heating element has a limited lifespan and is a consumable. It needs to be replaced after a certain period of use, which increases costs and reduces the practicality of the feeding device for silicone rubber molding material production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a feeding device for the production of silicone rubber impression materials. This device allows for a large heating area inside the mixing tank, enabling the material to reach a constant temperature more quickly. The use of water bath heating reduces costs and facilitates widespread adoption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of silicone rubber impression material, comprising a base, a heating seat fixedly installed on the top of the base, and a mixing tank fixedly installed on the top of the heating seat; A heating box is fixedly installed on the top of the heating base at the outer end of the mixing tank. A heat-conducting plate is fixedly installed on the outer end of the heating box. The heat-conducting plate is in contact with the outer end of the mixing tank.

Track blocks 64 are slidably connected to the outer ends of the two electric slide rails 63. An inner protective shell 65 is fixedly installed between the two track blocks 64. The inner protective shell 65 is located at the outer end of the heating box 4.

[0020] The height of the protective component 6 is adjustable. The protective component 6 can protect the outer end of the heating box 4 to prevent workers from being burned by the heating box 4, thus facilitating the protection of workers.

[0021] Please see Figure 1 , Figure 2 and Figure 4 The crushing assembly 8 includes an L-shaped plate 81, which is fixedly installed on one side of the feed pipe 7. A drive motor 82 is fixedly installed on one side of the L-shaped plate 81. A main gear 83 is fixedly installed at the output end of the drive motor 82. A driven gear 84 is meshed with one side of the main gear 83. Movable seats 85 are fixedly installed on one side of both the driven gear 84 and the main gear 83. The movable seats 85 are rotatably connected to the inner wall of the feed pipe 7. A crushing roller 86 is fixedly installed on one side of the movable seat 85.

[0022] The crushing component 8 can crush the mixed materials required for silicone rubber molding materials, preventing larger materials from being transferred into the mold and affecting the molding effect, thus protecting the quality of silicone rubber molding material production.

[0023] Please see Figure 1 , Figure 2 and Figure 5 The stirring assembly 9 includes a servo motor 91, which is fixedly installed on the top of the mixing tank 3.
