Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a sealing mechanism for the top cover of a dough mixer. Background Technology

[0002] Traditional dough mixers typically use a rotating or separate lid design, leaving a gap between the lid and the mixing hopper. This gap is particularly pronounced in dough mixers with a hopper that can be flipped to the sides. During the initial mixing stage, after adding water and stirring, some dry flour that hasn't been mixed with water will spray out from the gap between the lid and the hopper as it rotates and is stirred. This not only wastes flour but also creates dust and negatively impacts the workshop environment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sealing mechanism for the top cover of a dough mixer. This mechanism uses an upper-pressing method combined with a B-shaped sealing strip to seal the open end of the dough hopper, ensuring that flour does not escape from the hopper and cause dust when adding flour and water for kneading.

[0004] This utility model is achieved through the following technical solution:

[0005] A sealing mechanism for the top cover of a dough mixer is provided, comprising a dough hopper rotatably mounted on the dough mixer frame and a top cover matching the open end of the dough hopper. The two sides of the top cover are connected to the frame by vertically mounted lifting cylinders. A dough inlet is provided through the top surface of the top cover and connected to a dough inlet pipe. A water inlet and an exhaust port are provided through the top surface of the top cover on both sides of the dough inlet. A water inlet pipe is connected to the water inlet, and a flour filter screen is installed at the exhaust port. A sealing strip with a B-shaped cross-section and connected end to end is installed on the open end face of the dough hopper. The sealing strip is fixed to the open end face of the dough hopper by a strip plate provided in the middle and screws.

[0006] Furthermore, long, right-angled bent plates are welded and fixed to the upper front and back of the flour hopper. The upper plane of the long, bent plates is flush with the front and back of the flour hopper, respectively, and sealing strips are fixed to the upper surface of the long, bent plates.

[0007] The upper part of the top and the upper part of the back of the noodle bucket are fixed with sealing strips by long bent plates. On the one hand, the upper part of the long bent plates can increase the contact area between the noodle bucket and the top cover, which can be used in conjunction with the sealing strip to complete the front and back sealing. On the other hand, it can reduce the pressure of the noodle bucket and improve the stability of the top cover when it is pressed down.

[0008] Furthermore, the front edge and the back edge of the top cover are both bent upwards to form pressure plates for pressing and engaging with the sealing strips on the upper part of the front and back surfaces of the hopper.

[0009] The top and back edges of the cover are bent to form pressure plates. The pressure plates increase the contact area between the cover and the hopper, ensuring the stability of contact with the sealing strip and improving the stability of downward pressure.

[0010] Preferably, the top cover has baffles extending downwards from both sides of the lifting cylinder to separate the two sides of the bucket.

[0011] The top cover has baffles on both sides. When the top cover is pressed down, the baffles on both sides can be used to seal the sides of the container, which can enhance the sealing effect on the container and improve the sealing performance.

[0012] Furthermore, each baffle has a support plate vertically connected to its bottom surface at both ends for connection with the piston rod of the lifting cylinder.

[0013] Both ends of the baffle are vertically connected to the support plate. The support plate is connected to the piston rod of the lifting cylinder. The lifting cylinder can be used to drive the upper cover to move up and down, thereby realizing the opening and closing operation of the bucket.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a lifting cylinder to control the up-and-down movement of the top cover, enabling the opening and closing of the dough container. When the top cover is pressed down, the sealing strip on the bottom surface of the top cover and the open end of the dough container press against each other to seal the open end of the dough container. When adding water and flour for kneading, the flour-containing air that rises in the dough container can be discharged through the exhaust port, and the flour will be filtered by the flour filter screen and will not escape, thus not affecting the progress of adding water and flour. By pressing down the top cover, the open end of the dough container can be sealed, preventing dust from rising and flour from escaping during kneading, thereby improving the cleanliness of the kneading workshop.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figures 1-3 As shown, a sealing mechanism for the top cover of a dough mixer includes a dough hopper 2 rotatably mounted on the dough mixer frame 1 and a top cover 4 that matches the open end of the dough hopper 2. The two sides of the top cover 4 are connected to the frame 1 by vertically mounted lifting cylinders 3. A dough feeding port 6 is opened through the top surface of the top cover 4 and connected to a dough feeding pipe. A water feeding port 5 and an exhaust port 7 are respectively opened through the top surface of the top cover 4 on both sides of the dough feeding port 6. A water feeding pipe is connected to the water feeding port 5, and a flour filter screen is installed at the exhaust port 7. A sealing strip 11 with the ends connected and the cross section in the shape of a B is installed on the open end face of the dough hopper 2. The sealing strip 11 is fixed to the open end face of the dough hopper 2 by a strip plate 13 set in the middle and screws 12.

[0023] The upper front and upper back of the noodle bucket 2 are both welded and fixed with long strip bent plates 14 with right angles in cross section. The upper plane of the long strip bent plates 14 is flush with the front and back of the noodle bucket 2, respectively, and the sealing strips 11 are fixed to the upper surface of the long strip bent plates 14.

[0024] To improve the stability of the press-fit between the top cover 4 and the noodle hopper 2, the front edge and the back edge of the top cover 4 are both bent upward to form a pressure plate 9 for pressing and fitting with the sealing strip 11 on the upper part of the front and back surfaces of the noodle hopper 2.

[0025] The upper cover 4 has baffles 10 extending downwards from both sides of the lifting cylinder 3 to separate the two sides of the bucket 2. After the upper cover 4 is pressed down, the baffles 10 can be located outside the two sides of the bucket 2 and in contact with the two sides of the bucket 2, which can further improve the sealing of the sides.

[0026] Each baffle 10 has a support plate 8 vertically connected to its two bottom ends for connecting to the piston rod of the lifting cylinder 3.

[0027] The working process of this utility model:

[0028] By controlling the lifting cylinder 3, the piston rod is retracted, and the lifting cylinder 3 drives the upper cover 4 to press down, so that the bottom edge of the upper cover 4 is pressed down to the open end face of the noodle hopper 2. The pressure plates 9 on the front and back edges of the upper cover 4 abut against the upper edges of the long strip bent plates 14 on the front and back of the noodle hopper 2. At this time, the sealing strip 11 is compressed and deformed, so that the front and back of the noodle hopper 2 are sealed at the joint with the upper cover 4. Similarly, the sealing strips 11 on the upper edges of the two sides of the noodle hopper 2 are pressed down by the bottom surfaces of the two sides of the upper cover 4, which also ensures the sealing performance. There are also baffles extending downward on both sides of the upper cover 4 to block the two sides of the noodle hopper 2. 10 can further isolate the flour. Then, a certain amount of flour is added to the flour hopper through the addition pipe using the elevator and the addition pipe. At the same time, a certain amount of purified water is added to the flour hopper 2 through the water addition pipe. The mixing shaft of the dough mixer is started to mix and knead the dough. During the process of adding water and flour, the flour-containing air mixture in the flour hopper 2 will escape to the outside of the flour hopper 2 through the exhaust port 7. The flour is filtered through the flour filter screen at the exhaust port 7 to ensure that the air is discharged while the flour does not escape. This ensures that the flour does not escape when the flour hopper 2 is kneading, thus ensuring the cleanliness of the dough kneading workshop and avoiding flour dust.

[0029] After the dough is kneaded, the piston rod of the lifting cylinder 3 is extended to lift the top cover 4 and separate it from the dough hopper 2. The dough hopper 2 is then rotated forward to remove the kneaded dough from the hopper 2.
