Description

Technical Field

[0001] This utility model relates to a vacuum dough mixer, belonging to the technical field of food machinery and equipment. Background Technology

[0002] Currently, with the booming development of the food processing industry, the demand for pasta products is experiencing explosive growth. From traditional pastries to industrialized frozen foods, the market demand for dough and other raw materials is rising sharply. However, traditional dough mixers are limited by their equipment structure and technology, resulting in limited capacity per batch and long production cycles. They generally suffer from low mixing efficiency and poor dough uniformity, leading to low output per unit time and making it difficult to meet the mass production needs of large-scale food enterprises and large catering establishments. Existing dough mixers can no longer meet the needs of customers with high-volume requirements, and their limitations in output are becoming increasingly apparent, necessitating the development of high-capacity dough mixers to meet customer demands. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problems existing in the prior art and provide a vacuum dough mixer that can improve work efficiency and meet the demand for large production.

[0004] The technical solution of this utility model to solve its technical problem is as follows: A vacuum dough mixer includes a frame and a main shaft assembly mounted on the frame. The main shaft assembly is provided with a cylinder, and the cylinder is provided with a flip-out cylinder cover assembly. The cylinder cover assembly is provided with a cylinder cover water channel. One end of the main shaft assembly is connected to the main shaft motor through a sprocket transmission mechanism, and the other end is connected to the flip motor through a belt transmission mechanism.

[0005] The further improved technical solution of this utility model is as follows:

[0006] Preferably, a bearing is provided between the spindle assembly and the cylinder.

[0007] Preferably, the sprocket transmission mechanism includes a main shaft sprocket, a transmission chain, and a motor sprocket. One end of the main shaft assembly passes through the cylinder wall and is connected to the main shaft sprocket. The main shaft sprocket is connected to the motor sprocket via the transmission chain. The motor sprocket is installed at the output end of the main shaft motor.

[0008] With the above structure, the main spindle motor drives the motor sprocket to rotate, and the motor sprocket drives the main spindle sprocket to rotate through the chain. The main spindle assembly is connected to the spindle housing through bearings, and the main spindle sprocket drives the main spindle beater to rotate and knead the dough.

[0009] Preferably, the belt drive mechanism includes a rotary reducer, a pulley, a belt, and a drive pulley. The other end of the main shaft assembly passes through the cylinder wall and is connected to the rotary reducer. The rotary reducer is connected to the pulley. The pulley is connected to the drive pulley via the belt. The drive pulley is installed at the output end of the reversing motor.

[0010] With the above structure, the tilting motor drives the pulley to rotate through the drive pulley and V-belt. The pulley then drives the rotary reducer to tilt, and the rotary reducer drives the cylinder to tilt, thus completing the turning action.

[0011] Preferably, the cylinder cover assembly includes a cylinder, a cylinder cover water passage, and a flip cover, wherein the cylinder is connected to the flip cover, and the cylinder cover water passage is fixed on the flip cover main shaft.

[0012] Preferably, the cylinder piston rod is connected to the flip cover main shaft of the flip cover via a rocker arm.

[0013] In this way, the flipping motion of the cover is completed by a cylinder, realizing the opening and closing of the flipping cover.

[0014] Preferably, the water inlet of the cylinder cover water passage is connected to a water source through a water supply pipeline, and the water outlet is connected to the interior of the cylinder.

[0015] Preferably, the water supply pipeline is connected to a ball valve.

[0016] In this way, as the flour tumbles inside the drum, a certain amount of water is injected into the drum through the water passage in the lid. When water needs to be added during the kneading process, the ball valve is opened, and water enters the drum through the water passage to mix with the flour. This, combined with the rotation of the main shaft and the beater, completes the kneading operation.

[0017] Preferably, a shaft housing is installed at each end of the spindle assembly, the shaft housing is connected to the cylinder, and a bearing is provided between the spindle, the shaft housing, and the cylinder.

[0018] Preferably, the interior of the cylinder is connected to a vacuum pump via a vacuum tube.

[0019] The advantages of this utility model are that the overall structure is compact, it is installed on the frame, occupies little space, and facilitates the installation and disassembly of the equipment within the effective space. Through structural optimization, the production cost is reduced and the capacity is large, which significantly improves work efficiency. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the examples given.

[0027] like Figures 1 to 3 As shown, a vacuum dough mixer includes a frame 4 and a spindle assembly 3 mounted on the frame 4. Shaft housings 11 are mounted at both ends of the spindle assembly 3, and the shaft housings 11 are fixedly connected to a cylinder 2 by screws. The interior of the cylinder 2 is connected to a vacuum pump via a vacuum tube. A pneumatic ball valve 6 is installed on the vacuum tube and mounted on a cylinder cover assembly 5 to control the exhaust of the exhaust channel, thereby achieving a vacuum inside the cylinder 2. A flip-up cylinder cover assembly 5 is provided on the cylinder 2, movably connected to the cylinder 2. The cylinder cover assembly 5 has a cylinder cover water passage 503. The spindle assembly 3 is driven to rotate by a spindle motor 8. One end of the spindle assembly 3 is connected to the spindle motor 8 via a sprocket transmission mechanism. The spindle motor 8 includes a spindle sprocket 10, a transmission chain, and a motor sprocket 9. One end of the spindle assembly 3 passes through the cylinder wall of the cylinder 2 and is connected to the spindle sprocket 10. The spindle sprocket 10 is connected to the motor sprocket 9 via the transmission chain. The motor sprocket 9 is mounted on the output end of the spindle motor 8. The main spindle motor 8 is connected to the main spindle assembly 3 via a motor sprocket 9, a transmission chain, and a main spindle sprocket 10, driving the main spindle assembly 3 to rotate within the cylinder 2 for dough kneading. The main spindle motor 8 is a variable frequency speed control motor. Additionally, the frame 4 is a single load-bearing structure formed by welding several sheet metal plates. A sheet metal assembly 1 is also installed on the frame 4; this assembly is a protective cover made of sheet metal and located on the outside of the frame 4, used to protect the entire dough kneading machine from external interference.

[0028] like Figure 5As shown, the other end of the main shaft assembly 3 is connected to the tilting motor 7 via a belt drive mechanism. The other end of the main shaft assembly 3 passes through the cylinder wall of the cylinder 2 and is connected to the rotary reducer 12. The rotary reducer 12 is connected to the pulley 13, which is connected to the drive pulley via a belt. The drive pulley is installed at the output end of the tilting motor 7, causing the tilting motor 7 to drive the rotary reducer to rotate. Meanwhile, bearings (which can be rolling or sliding bearings) are installed between the main shaft assembly 3, the shaft housing 11, and the cylinder 2. These bearings allow the main shaft assembly 3 to rotate independently relative to the shaft housing 11 and the cylinder 2, while also ensuring a rigid connection between the main shaft assembly 3 and the shaft housing 11. Thus, when the main shaft motor 8 drives the main shaft assembly 3, it rotates relative to the cylinder 2 and the shaft housing 11, rotating within the cylinder 2. When the tilting motor 7 drives the main shaft assembly 3, it can drive the cylinder 2 to tilt together via the shaft housing 11. During the rotation, the rotation motor 7 drives the rotary reducer 12 via the drive pulley, belt, and pulley 13. The rotary reducer 12 transmits power to the main shaft assembly 3. The main shaft assembly 3, through the shaft housing 11, rotates around the axis of the cylinder 2. At this time, there is no relative movement between the main shaft assembly 3 and the cylinder 2; they rotate synchronously, achieving rotational unloading. The main shaft assembly 3 includes a main shaft and a set of stirring blades mounted on the main shaft. When the main shaft motor 8 operates, power is transmitted to the main shaft assembly 3 via a chain. The main shaft assembly 3 rotates independently relative to the cylinder 2 under the support of bearings, driving the stirring blades on the main shaft. At this time, the cylinder 2 can remain stationary.

[0029] The tilting motor 7 and the main shaft motor 8 are connected to the control output terminals of the control box, and the signal input terminal of the control box is connected to the control box. A vacuum sensor is installed inside the cylinder 2, and the vacuum sensor is connected to the signal acquisition terminal of the control box.

[0030] The cap assembly 5 is movably connected to the upper port of the cylinder 2, and the cap assembly 5 and the cylinder 2 are sealed together by a sealing strip. During dough kneading, the cap assembly 5 is sealed to the upper port of the cylinder 2; during material feeding, the cap assembly 5 separates from the upper port of the cylinder 2. Figure 4As shown, the cylinder cover assembly 5 includes a cylinder 501, a ball valve 502, a cylinder cover water passage 503, and a flip cover 504. The ball valve 502 is mounted on the flip cover 504. The flip cover 504 consists of a flip cover body and a flip cover spindle 505. The flip cover body can rotate around the flip cover spindle 505. The cylinder 501 is connected to the flip cover 504. The rotation of the flip cover 504 is achieved by the extension and retraction of the cylinder 501, thereby realizing the automatic opening and closing of the flip cover 504. The cylinder body of the cylinder 501 is connected to the frame 4 through a hinge, and the piston rod of the cylinder 501 is connected to the flip cover spindle 505 of the flip cover 504 through a rocker arm. During operation, compressed air is introduced into cylinder 501, and the piston rod extends under the action of air pressure, pushing the rocker arm to swing upward around the main shaft 505 of the flip cover, causing the flip cover body to rotate around the main shaft 505 of the flip cover until the preset angle is reached, and the flip cover 504 is opened; when air is introduced into cylinder 501 in the opposite direction, the piston rod retracts under the action of air pressure, pulling the rocker arm to swing downward around the main shaft 505 of the flip cover, and the flip cover body rotates in the opposite direction with the main shaft 505 of the flip cover, resetting from the open state to the closed state, completing the closing.

[0031] In addition, the water passage 503 of the cylinder cover is fixed on the main shaft 505 of the flip cover. The water inlet of the water passage 503 is connected to the water source through a water supply pipe, and the water outlet is connected to the inside of the cylinder body 2. Water is added to the inside of the cylinder body 2 through the water passage 503 to ensure the quality of the dough. The water supply pipe is connected to the ball valve 502 to facilitate the control of the amount of water added and prevent the failure of the kneading process due to excessive water addition. The water passage 503 of the cylinder cover includes a main water passage and several branch outlets evenly arranged on the main water passage. The branch outlets are water outlets, one end of which is connected to the main water passage, and the other end of the branch outlet is connected to the inside of the cylinder body 2. The main water passage is provided with a water inlet connected to the water supply pipe. The ball valve 502 and the start ball valve 6 are integrated in the control box installed on the cylinder cover assembly 5. A vacuum butterfly valve is also provided on the flip cover 504, which can realize the addition of flour in the vacuum mixing drum or the vacuum sealing under the negative pressure working state of the vacuum mixing drum in a limited space. For the specific structure, see CN221323304U.

[0032] Before operating the vacuum dough mixer, flour is fed into the drum 2. When a certain amount of flour has been added, the drum cover assembly 5 is closed, and water is supplied to the drum 2 in a measured amount. The water enters the drum 2 through the water passage 503 in the drum cover. After the flour and water are mixed in a certain proportion, the main shaft motor 508 is turned on to drive the main shaft assembly 3 to rotate. Simultaneously, the rotation of the main shaft assembly 3 causes the flour to rotate inside the drum 2. When additional mixture needs to be added, the cylinder 501 is vented and extended to rotate the drum cover assembly 5, opening it. After the mixture has been added, the cylinder 501 retracts to close the drum cover assembly 5. The drum cover assembly 5 and the drum 2 are sealed together by a sealing strip. After the dough mixer has finished kneading, the cylinder 501 is vented again to rotate the drum cover assembly 5, opening it. After the lid assembly 5 is opened, the flipping motor 7 is activated. The flipping motor 7 drives the rotary reducer 12 via a pulley and belt. The rotary reducer 12 drives the drum 2 to flip, so that the flour is poured out of the drum 2. After the flour is poured out, the drum 2 returns to its original position, and the lid assembly 5 closes. Thus, the dough mixer works in this cycle.

[0033] The device of this utility model is installed on the frame 4, and the continuous and smooth kneading is achieved through frequency conversion speed regulation control, which significantly improves the working efficiency of the dough kneading machine.

[0034] The device of this invention replaces the complex square tube welding structure of the original dough mixer with a plate welding structure, resulting in a simpler and easier-to-manufacture structure, reducing manual production time and thus lowering production costs. Furthermore, because the frame structure of the dough mixer is now plate welded, the absence of square tubes restricting the space on both sides of the cylinder allows for a slightly larger cylinder design, increasing its capacity. In addition, this invention employs automatic water and powder supply, eliminating the need for manual pouring, reducing the time spent opening and closing the cylinder lid and pouring water and powder, thereby improving work efficiency. Besides the above embodiments, this invention can also have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this invention.
