Description
Technical Field
[0001] The utility model relates to the technical field of vacuum mixers, in particular to a discharge door device for a vacuum mixer. Background Art
[0002] Vacuum mixer is a kind of equipment used to mix, stir and process various materials. It is widely used in laboratories, industrial production and scientific research. Since the operating environment is in a vacuum state, it can effectively prevent oxidation and contamination, which is especially important for materials that are easily oxidized or contaminated. In order to allow the operator to accurately control the flow of materials, it is ensured that the materials can be taken out as needed after the mixing process. The flow rate and flow of materials can be controlled by the adjustable opening and closing degree of the discharge door to meet different process requirements.
[0003] During the use of the traditional vacuum mixer discharge door device, the movable frame is driven to move along the limit slide rail through the telescopic cylinder so that the movable frame is directly in front of the discharge port, and then the screw is manually rotated, and the screw is pushed inward along the threaded barrel, thereby driving the cover door to advance toward the discharge port and closely contact with the discharge port. The sealing layer is on the inner end surface of the cover, and the sealing layer is in close contact with the side wall around the discharge port under the action of pressure, thereby achieving a sealing effect and having a good sealing effect.
[0004] However, in the use of traditional discharge door devices, the cover door only slides horizontally on the outer wall of the vacuum mixer by driving the movable frame through the telescopic cylinder, which causes the sealing ring to frequently rub against the outer wall of the mixer, causing the sealing ring to wear and affect the sealing effect of the cover door. The sealing ring needs to be replaced frequently, which increases the use cost of the vacuum mixer. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a discharge door device for a vacuum mixer, comprising a vacuum machine housing 1, a limiting groove 3 is provided inside the vacuum machine housing 1, a discharge pipe 2 is fixedly connected inside the vacuum machine housing 1, a slider 4 is provided on one side of the vacuum machine housing 1, the outer wall of the slider 4 is slidably connected inside the limiting groove 3, a connecting rod 1 5 is rotatably connected inside the slider 4, one end of the connecting rod 1 5 is rotatably connected to a connecting rod 2 6, a fixed block 1 7 is fixedly connected to the outer wall of the vacuum machine housing 1, a worm gear 8 is rotatably connected inside the fixed block 1 7, and a connecting rod 3 12 is rotatably connected inside the worm gear 8, One end of the connecting rod three 12 is rotatably connected to the inside of the connecting rod two 6, and one end of the connecting rod two 6 is rotatably connected to the cover door 13, and a sealing component is provided on one side of the cover door 13. The outer wall of the cover door 13 is slidably connected to the inside of the discharge pipe 2, and the outer wall of the vacuum machine housing 1 is fixedly connected to the fixing block two 9, and one side of the fixing block two 9 is fixedly connected to the motor one 10, and the output end of the motor one 10 is fixedly connected to the worm 11, and the worm 11 is meshed with the outer wall of the worm wheel 8. The sealing component includes a sealing ring 14, one side of the sealing ring 14 is fixedly connected to one side of the cover door 13, and the other side of the sealing ring 14 is attached to the inside of the discharge pipe 2;
[0031] Specifically, when operating the vacuum machine, the action of opening the cover door 13 is achieved through a series of precise mechanical transmissions. The motor 10 is used as a power source, and its output end is closely connected to the worm 11. When the motor 10 is started, its power is transmitted through the worm 11, and the special tooth shape design between the worm 11 and the worm wheel 8 enables the worm wheel 8 to be driven to rotate. This rotational motion is converted into linear motion through the connecting rod 3 12, so that the connecting rod 3 12 is lifted. The lifting action of the connecting rod 3 12 is further transmitted to the cover door 13 through the connecting rod 2 6, so that it begins to open. The design of this connecting rod transmission mechanism not only makes the opening action of the cover door 13 more stable and reliable, but also can accurately control the angle of the cover door 13 by changing the angle of the connecting rod 2 6. The other end of the connecting rod 2 6 is connected to the slider 4 through the connecting rod 1 5. The slider 4 is limited inside the limit groove 3. This design ensures the stability and accuracy of the cover door 13 during the opening and closing process. The existence of the limiting groove 3 limits the moving range of the slider 4, thereby preventing the cover door 13 from being over-positioned or under-positioned when opening or closing.
[0032] It is worth mentioning that the sealing design between the cover door 13 and the discharge pipe 2. Through the use of the sealing ring 14, the cover door 13 and the discharge pipe 2 are tightly sealed, ensuring the integrity and stability of the vacuum environment. This sealing design cleverly avoids the friction between the sealing ring 14 and the outer wall of the vacuum machine housing 1 when the cover door 13 is opened and closed, thereby greatly extending the service life of the sealing ring 14 and reducing the frequency of maintenance and replacement.
[0033] Reference Figure 3 A feeding pipe 15 is fixedly connected to the top of the vacuum machine housing 1, and a sealing cover 16 is arranged inside the feeding pipe 15. A motor 2 17 is fixedly connected to the top of the vacuum machine housing 1, and a triangular bracket 20 is fixedly connected to the output end of the motor 2 17. A support rod 18 is fixedly connected to the inside of the vacuum machine housing 1, and a transmission gear 19 is fixedly connected to the bottom of the support rod 18. A driven gear 1 21 is rotatably connected to the inside of the triangular bracket 20, and the driven gear 1 21 is meshed with the outer wall of the transmission gear 19. A driven gear 2 22 is fixedly connected to the inside of the driven gear 1 21. A driven gear 3 23 is rotatably connected to the inside of the triangular bracket 20, and the driven gear 2 22 is meshed with the outer wall of the driven gear 3 23. A connecting rod 24 is fixedly connected to the inside of the driven gear 3 23, and one end of the connecting rod 24 is fixedly connected to a transmission shaft 25. A stirring blade 26 is fixedly connected to the outer wall of the transmission shaft 25, and a stirring shaft 27 is fixedly connected to the outer wall of the transmission shaft 25.
[0034] Specifically, when the mixing process begins, the operator will open the sealing cover 16 to ensure that the raw materials can enter the machine smoothly. Subsequently, the raw materials are put into the vacuum machine housing 1 through the feeding tube 15. At this time, the motor 2 17 starts to work, and its output end drives the triangular bracket 20 to rotate. The rotation of the triangular bracket 20 is not isolated, and there is a close linkage relationship between it and the transmission gear 19. The transmission gear 19 is firmly fixed inside the vacuum machine housing 1 through the support rod 18. When the triangular bracket 20 rotates, it drives the driven gear 1 21 to rotate. The design of the driven gear 1 21 is very clever. It is meshed on the outer wall of the transmission gear 19. Therefore, under the drive of the triangular bracket 20, the driven gear 1 21 will start to rotate. The self-rotation of the driven gear 1 21 is not the end point. It will further drive the driven gear 3 23 to rotate through the driven gear 2 22. The driven gear 3 23 is connected to the connecting rod 24. When the driven gear 3 23 rotates, it drives the connecting rod 24 to move. The other end of the connecting rod 24 is connected to the transmission shaft 25, so the transmission shaft 25 will also start to rotate. The rotation of the transmission shaft 25 is the core of the entire stirring process. Its outer wall is equipped with stirring blades 26, which cooperate with the stirring shaft 27 to efficiently stir the raw materials inside. During the stirring process, the transmission shaft 25 will not only revolve around the transmission gear 19 as the center of the circle, but also cooperate with the stirring through the rotation of the driven gear three 23. This unique design greatly improves the stirring efficiency of the vacuum mixer.
[0035] Working principle: When the discharge door device of the vacuum mixer is used, when the cover door 13 is opened, the output end of the motor 10 drives the worm 11 to rotate, and the worm 11 drives the connecting rod 3 12 to lift through the worm gear 8, and the connecting rod 3 12 drives the cover door 13 to open through the connecting rod 2 6, and the other end of the connecting rod 2 6 is connected to the slider 4 through the connecting rod 1 5, and the slider 4 is limited inside the limit groove 3, and the cover door 13 is sealed with the discharge pipe 2 through the sealing ring 14, so that the cover door 13 does not need to be rubbed with the outer wall of the vacuum machine housing 1 when it is opened and closed, and then the sealing cover 16 is opened during stirring, and the raw materials are put into the vacuum machine housing 1 through the feeding pipe 15, and then the output end of the motor 2 17 drives the triangular bracket 2 0 rotates, when the triangular bracket 20 rotates, since the transmission gear 19 is fixed to the inside of the vacuum machine housing 1 through the support rod 18, when the triangular bracket 20 drives the driven gear 1 21 to rotate, the driven gear 1 21 is meshed with the outer wall of the transmission gear 19, so that the driven gear 1 21 will rotate on its own, and the driven gear 1 21 drives the driven gear 3 23 to rotate through the driven gear 2 22, and the driven gear 3 23 drives the transmission shaft 25 to rotate through the connecting rod 24, and the transmission shaft 25 cooperates with the stirring shaft 27 through the stirring blade 26 on the outer wall to stir, so that when the transmission shaft 25 revolves around the transmission gear 19 as the center, stirring is carried out through the self-rotation cooperation of the driven gear 3 23, thereby improving the stirring efficiency of the vacuum mixer.
