Description
Technical Field
[0001] This invention relates to the field of mixer technology, and more particularly to a multi-stage sealed anti-splash food mixer. Background Technology
[0002] The working principle of a food mixer is to mix the mixture in the mixing bowl using a mixer. When kneading dough, it mixes and kneads flour and water to form a dough with a certain gluten network structure.
[0003] Currently, most conventional dough mixers on the market use an open-top structure or a simple closed-top structure. In practical applications, especially when the flour is initially mixed or the dough has a low moisture content, dry flour particles and later dough clumps are easily sprayed outwards along the mixing axis under the action of the high-speed rotating stirring hook, or thrown out from the gap between the bucket opening and the lid. This not only wastes raw materials, but the splashed powder also adheres to the machine surface and motor, which is not only difficult to clean, but long-term accumulation may also cause short circuits or malfunctions in the motor. If flour, water, or improvers need to be added midway through traditional equipment, it is usually necessary to stop the machine, open the bucket lid or top cover, and then add them. Stopping and restarting will affect the continuous gluten formation process, and the temperature difference between the inside and outside of the bucket at the moment of opening the lid will affect the quality of the dough (especially fermented dough). For large commercial dough mixers, the process of opening, aligning, and resealing is time-consuming and laborious. If the lid is forcibly opened before the machine has completely stopped, there is also a very high safety risk.
[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention
[0005] In view of this, the purpose of this invention is to provide a multi-stage sealed anti-splash food mixer to solve the problem that the dried flour particles and later dough flakes are easily sprayed outward along the mixing axis or thrown out from the gap between the bucket mouth and the bucket lid under the action of the high-speed rotating mixing hook.
[0006] To achieve the above objectives, the present invention provides a multi-stage sealed anti-splash food mixer, comprising a support frame and a support plate disposed above the support frame. The support frame is provided with a driver for driving the support plate to rotate. A mixing tank is disposed above the support plate. The support plate is provided with a positioning structure for positioning the mixing tank. A lifting seat is disposed above the mixing tank. The support frame is fixedly connected to several first hydraulic telescopic rods, and the telescopic ends of the first hydraulic telescopic rods are fixedly connected to the lifting seat. The lifting seat is rotatably fitted with a rotating seat. The top of the mixing tank is equipped with a sealing element that matches the rotating seat. The lifting seat is equipped with a feeding and mixing assembly.
[0007] Optionally, the sealing element includes a support ring fixedly fitted outside the mixing tank, a sealing gasket fixedly connected to the bottom of the rotating seat, and the bottom of the sealing gasket and the top of the support ring being in contact.
[0008] Optionally, a plurality of positioning posts are fixedly connected to the support ring, and a positioning sleeve is slidably fitted on the outside of the positioning posts, and the positioning sleeve and the rotating seat are fixedly connected.
[0009] Optionally, the feeding and mixing assembly includes a water inlet pipe fixedly installed on the lifting base, a spray pipe located inside the mixing tank fixedly connected to the bottom end of the water inlet pipe, a number of spray nozzles installed on the spray pipe, and a dough mixer and a sealed feeding structure respectively installed on the lifting base.
[0010] Optionally, the sealed feeding structure includes a feeding shell fixedly installed above the lifting seat. The bottom end of the feeding shell is fixedly connected to a feeding pipe, which passes through the lifting seat and is fixedly connected to the lifting seat. A piston plate is slidably provided inside the feeding shell. A second hydraulic telescopic rod is fixedly connected to the feeding shell. A mounting bracket is fixedly connected to the top of the piston plate, and the telescopic end of the second hydraulic telescopic rod is fixedly connected to the mounting bracket. An opening and closing unit that cooperates with the feeding pipe is installed on the piston plate.
[0011] Optionally, the opening and closing unit includes a first servo motor fixedly mounted on a piston plate, a first rotating shaft rotatably connected to the piston plate, and the output end of the first servo motor and the first rotating shaft fixedly connected. The outside of the first rotating shaft is fixedly fitted with a spiral blade that cooperates with the feed pipe, and the bottom end of the first rotating shaft is fixedly connected with a frustum that cooperates with the feed pipe, and the frustum is located below the feed pipe.
[0012] Optionally, the dough mixer includes a stirring hook rotatably mounted on a lifting base, and the stirring hook is located inside a mixing drum. A second servo motor is fixedly connected to the lifting base, and the output end of the second servo motor is fixedly connected to the stirring hook.
[0013] Optionally, the driver includes a second rotating shaft fixedly mounted on the bottom of the support plate, the second rotating shaft being rotatably connected to the support frame, a third servo motor being fixedly connected to the support frame, and the output end of the third servo motor being fixedly connected to the second rotating shaft.
[0014] Optionally, a number of rollers are fixedly connected to the bottom of the support plate, and the bottom of the rollers is in contact with the top of the support frame.

[0016] The beneficial effects of this invention are as follows: Through the positioning structure on the support plate and the drive of the first hydraulic telescopic rod, precise alignment and automatic sealing of the mixing drum and the rotating seat are achieved, ensuring that the seal is uniformly compacted. This reduces the operator's technical requirements and labor intensity. The lifting seat moves the rotating seat down to a preset position, pressing the seal against the connection between the mixing drum and the rotating seat. Continuous downward pressure is applied hydraulically, ensuring the seal remains in place even under vibration and wear, thus preventing splashing. Flour and water can be added without opening the mixing drum during the kneading process, maintaining stable operating conditions. For fermented dough, opening the lid causes sudden changes in internal temperature and humidity, affecting fermentation quality. This invention improves efficiency and safety, avoids frequent start-ups and shutdowns, and eliminates the safety hazards of reaching out to open the lid and add materials while the machine is running. It ensures the feed inlet is completely sealed when no material is needed, only temporarily opening it when additional material is required. This avoids the large-scale dust leakage caused by traditional equipment requiring the entire lid to be opened. The operator can fine-tune the water-to-flour ratio in real time according to the dough's forming state, ensuring consistent kneading results. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.
[0021] Example 1, by Figure 1 and Figure 2 The present invention includes a support frame 1 and a support plate 2 disposed above the support frame 1. The support frame 1 is provided with a driver for driving the support plate 2 to rotate. A stirring tank 3 is disposed above the support plate 2. The support plate 2 is provided with a positioning structure for positioning the stirring tank 3. A lifting seat 4 is disposed above the stirring tank 3. Several first hydraulic telescopic rods 5 are fixedly connected to the support frame 1, and the telescopic ends of the first hydraulic telescopic rods 5 are fixedly connected to the lifting seat 4. A rotating seat 6 is rotatably sleeved on the outside of the lifting seat 4. A sealing element adapted to the rotating seat 6 is installed on the top of the mixing drum 3. A feeding and mixing component is installed on the lifting seat 4. The operator places the mixing drum 3 containing flour on the support plate 2, positions the mixing drum 3 by the positioning structure on the support plate 2, and then drives the lifting seat 4 and the rotating seat 6 to move down to the preset position by the first hydraulic telescopic rods 5 so that the sealing element seals the connection between the mixing drum 3 and the rotating seat 6. An appropriate amount of water or flour is added to the mixing drum 3 by the feeding and mixing component, and the flour and water in the mixing drum 3 are stirred by the feeding and mixing component. Flour and water can be added without opening the mixing drum 3 during the kneading process. Through the positioning structure on the support plate 2 and the drive of the first hydraulic telescopic rods 5, the precise alignment of the mixing drum 3 and the rotating seat 6 is achieved. The automatic pressing and sealing mechanism ensures that the seal is evenly compacted, reducing the operator's technical requirements and labor intensity. The lifting seat 4 drives the rotating seat 6 to move down to the preset position, pressing the seal against the connection between the mixing tank 3 and the rotating seat 6. Continuous downward pressure is applied hydraulically, ensuring that the seal remains in place even under vibration and wear, thus preventing splashing. Flour and water can be added without opening the mixing tank 3 during the kneading process, maintaining stable operating conditions. For fermented doughs, opening the lid can cause sudden changes in internal temperature and humidity, affecting fermentation quality. This improves efficiency and safety, avoids frequent start-ups and shutdowns, and eliminates the safety hazards of reaching out to open the lid and add materials while the machine is running. The feed inlet is completely sealed when no materials are needed, and is only temporarily opened when additional materials are required. This avoids the large-scale dust leakage caused by opening the entire lid in traditional equipment. The operator can fine-tune the water-to-flour ratio in real time according to the dough's forming state, ensuring consistent kneading results.
[0022] Example 2, based on Example 1, is... Figure 2 , Figure 3 and Figure 5 The sealing element includes a support ring 7 fixedly sleeved on the outside of the mixing tank 3, a sealing gasket 8 fixedly connected to the bottom of the rotating seat 6, and the bottom of the sealing gasket 8 is in contact with the top of the support ring 7. A plurality of positioning pins 9 are fixedly connected on the support ring 7, and a positioning sleeve 10 is slidably sleeved on the outside of the positioning pins 9, and the positioning sleeve 10 is fixedly connected to the rotating seat 6. When the lifting seat 4, rotating seat 6 and sealing gasket 8 move down to the preset height, the bottom of the sealing gasket 8 is in close contact with the top of the support ring 7, and the positioning post 9 passes through the corresponding positioning sleeve 10. When the mixing tank 3 rotates, the mixing tank 3 drives the rotating seat 6 and positioning sleeve 10 to rotate relative to the lifting seat 4 through the support ring 7 and positioning post 9, so as to prevent the support ring 7 from sliding relative to the sealing gasket 8 and ensure the sealing of the connection between the support ring 7 and the sealing gasket 8.
[0023] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 and Figure 4 The feeding and mixing assembly includes a water inlet pipe 11 fixedly installed on the lifting base 4. The bottom end of the water inlet pipe 11 is fixedly connected to a spray pipe 12 located inside the mixing tank 3. Several nozzles are installed on the spray pipe 12. A dough mixer and a sealed feeding structure are respectively installed on the lifting base 4. The sealed feeding structure includes a feeding shell 13 fixedly installed above the lifting base 4. The bottom end of the feeding shell 13 is fixedly connected to a feeding pipe 14, which penetrates the lifting base 4 and is fixedly connected to it. A piston plate 15 is slidably disposed inside the feeding shell 13. A second hydraulic telescopic rod 16 is fixedly connected to the feeding shell 13. A mounting bracket 17 is fixedly connected to the top of the piston plate 15, and the telescopic end of the second hydraulic telescopic rod 16 is fixedly connected to the mounting bracket 17. The plate 15 is equipped with an opening and closing unit that cooperates with the feed pipe 14. The opening and closing unit includes a first servo motor 20 fixedly installed on the piston plate 15. A first rotating shaft 18 is rotatably connected to the piston plate 15, and the output end of the first servo motor 20 is fixedly connected to the first rotating shaft 18. A spiral blade 19 that cooperates with the feed pipe 14 is fixedly sleeved on the outside of the first rotating shaft 18. A frustum 21 that cooperates with the feed pipe 14 is fixedly connected to the bottom end of the first rotating shaft 18, and the frustum 21 is located below the feed pipe 14. The dough mixer includes a stirring hook 22 rotatably installed on the lifting seat 4, and the stirring hook 22 is located inside the mixing tank 3. A second servo motor 23 is fixedly connected to the lifting seat 4, and the output end of the second servo motor 23 is fixedly connected to the stirring hook 22. Water enters the spray pipe 12 through the water inlet pipe 11, and the water can be sprayed into the mixing tank 3 through the nozzles on the spray pipe 12. When the mixing tank 3 and the rotating seat 6 rotate relative to the lifting seat 4, the nozzles can spray water into different positions in the mixing tank 3. At the same time, the second servo motor 23 drives the stirring hook 22 to rotate, and the stirring hook 22 can stir the flour and water in the mixing tank 3. When it is necessary to add flour to the mixing tank 3, it is not necessary to open the mixing tank 3. The second hydraulic telescopic rod 16 drives the mounting bracket 17 and the piston plate 15 to move down, and the first rotating shaft 18 drives the spiral blade 19 and the truncated cone 21 to move down. The truncated cone 21 is no longer in contact with the bottom end of the feed pipe 14, so that the feed pipe 14 is in the open state. The first servo motor 20 drives the first rotating shaft 18 and the spiral blade 19 to rotate, and the flour in the upper shell 13 can be discharged through the feed pipe 14. The flour falls onto the truncated cone 21 and slides down the arc surface of the truncated cone 21 into the mixing tank 3.
[0024] Example 4, based on Example 1, by Figure 1 and Figure 6The drive includes a second rotating shaft 26 fixedly mounted on the bottom of the support plate 2. The second rotating shaft 26 is rotatably connected to the support frame 1. A third servo motor 27 is fixedly connected to the support frame 1, and the output end of the third servo motor 27 is fixedly connected to the second rotating shaft 26. Several rollers 32 are fixedly connected to the bottom of the support plate 2, and the bottom of the rollers 32 is in contact with the top of the support frame 1. The positioning structure includes a loading plate 28 set above the support plate 2. Several positioning holes 25 are opened on the loading plate 28. Positioning blocks 24 are provided in the positioning holes 25, and the top of the positioning blocks 24 is fixedly connected to the bottom of the mixing tank 3. The bottom of the mixing tank 3 is in contact with the top of the loading plate 28. Several guide posts 29 are fixedly connected to the bottom of the loading plate 28. The guide posts 29 penetrate the support plate 2. A fixed plate 30 is fixedly connected to the bottom end of the guide posts 29. A compression spring 31 is sleeved on the outside of the guide posts 29, and the two ends of the compression spring 31 are fixedly connected to the bottom of the loading plate 28 and the top of the support plate 2, respectively. The mixing tank 3 is placed on the carrying tray 28, and the positioning block 24 at the bottom of the mixing tank 3 is inserted into the corresponding positioning hole 25. When the rotating seat 6 drives the sealing gasket 8 to press on the support ring 7, the rotating seat 6 pushes the support ring 7, the mixing tank 3 and the carrying tray 28 to move down relative to the support plate 2. The compression spring 31 is in a compressed state, ensuring that the bottom of the sealing gasket 8 and the top of the support ring 7 are in close contact. When the third servo motor 27 drives the second rotating shaft 26 and the support plate 2 to rotate, the support plate 2 drives the carrying tray 28, the positioning block 24 and the mixing tank 3 to rotate synchronously through the guide column 29. The support plate 2 drives the roller 32 to roll on the support frame 1. The design of the roller 32 reduces the possibility of tilting and swaying during the rotation of the support plate 2, and increases stability.
