Description
Technical Field
[0001] The utility model relates to the field of seasoning production equipment, in particular to a powdery seasoning mixing device. Background Technique
[0002] During the production process of powdery seasonings, in order to make the taste of the seasonings rich and diverse, multiple seasoning powders are generally mixed, usually through a seasoning mixing device. During the mixing process of the seasoning powders, to ensure uniform mixing, the stirring structure of traditional seasoning mixing devices generally performs a relatively fast circular motion, resulting in a large amount of dust generated. Moreover, when the lid is opened after mixing, due to the sudden change in air pressure inside and outside the seasoning mixing device, a large airflow is generated, blowing the dust inside the seasoning mixing device into the outside air, thus having an adverse impact on the production environment and operating personnel.
[0003] Therefore, it is necessary to design a powdery seasoning mixing device to alleviate the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a powdery seasoning mixing device to overcome the above-mentioned defects in the prior art.
[0005] According to a powdery seasoning mixing device of the utility model, it includes a housing. The interior of the housing is hollow and open at the upper end. A mixing component that rotates reciprocally in both forward and reverse directions is arranged inside the housing, and a cover component that reduces the escape of dust through negative pressure is slidably connected inside the housing.
[0006] Through the above technical solution, the mixing component rotates inside the housing to mix the seasonings inside the housing evenly. During the mixing process of the seasonings, the cover component can reduce the escape of seasonings to the outside. At the same time, during the process of opening the cover, since the chamber space formed by the cover component and the inner cavity of the housing becomes larger, a negative pressure is formed, so that the outside air is inhaled into the housing through the cover component, avoiding the sudden change in air pressure when opening the cover component and generating an airflow, and further preventing the seasoning dust from escaping to the outside.
[0007] The utility model is further arranged as follows: The mixing component includes a central rotating shaft, and a plurality of mixing rods that are circumferentially and evenly distributed around the central rotating shaft are fixed on the outer periphery of the central rotating shaft.
[0008] Through the above technical solution, the plurality of mixing rods rotate with the rotation of the central rotating shaft, so as to mix and stir the seasonings inside the housing.
[0009] The present utility model is further configured as follows: The middle part of the mixing rod is a vertical part, and its upper and lower ends are horizontal parts. One end of the horizontal part of the mixing rod is fixed on the outer periphery of the central rotating shaft, and a mixing plate is rotatably connected to the vertical part of the mixing rod.
[0010] Through the above technical solution, the mixing plate increases the contact area with the mixing rod and the seasoning dust, thereby increasing the stirring effect.
[0011] The present utility model is further configured as follows: The position where the mixing plate is rotatably connected to the mixing rod is far from the central axis of the mixing plate, and the mixing rod reciprocates forward and backward in the shell with the central rotating shaft as the center.
[0012] Through the above technical solution, as the mixing rod reciprocates forward and backward, the mixing plate will swing back and forth, thereby further increasing the stirring effect of the mixing assembly, so that the mixing assembly can ensure the uniform mixing of the seasoning under slow rotation and reduce the generation of dust.
[0013] The present utility model is further configured as follows: The cover assembly includes a cover plate and a plurality of air pipes arranged in the cover plate. The air pipes are slidably matched with the internal cavity of the shell. A limiting ring protruding inward is fixed on the inner side wall of the shell, and the lower end of the cover plate can be abutted against the limiting ring. The plurality of air pipes are circumferentially and evenly distributed with the axis of the cover plate as the center. The air pipes penetrate through the cover plate, and the central rotating shaft penetrates through the cover plate.
[0014] Through the above technical solution, when the cover plate is opened, the space formed by the cover plate and the internal cavity of the shell increases to form a negative pressure, and the outside air enters the shell through the air pipes, so that the air pressure in the internal cavity of the shell is balanced with the outside air pressure, reducing the air pressure change when the shell is opened, and further reducing the influence of the air flow on the seasoning dust.
[0015] The present utility model is further configured as follows: A filter element is fixed in the air pipe, a convex block is slidably connected inside the upper end of the air pipe, and a connecting ring is arranged on the upper side of the cover plate. A plurality of the convex blocks are all fixed on the lower end of the connecting ring.
[0016] Through the above technical solution, the filter element can slow down the flow rate of the air passing through the air pipe, thereby reducing the air flow rate entering the shell. At the same time, the convex block blocking the air pipe can prevent the seasoning dust from being discharged through the air pipe.
[0017] The present utility model is further configured as follows: Two symmetrically arranged bayonets are opened at the upper end of the shell, a limiting plate that can be clamped into the bayonets is arranged on the upper side of the shell, a connecting block is fixedly connected between the limiting plate and the cover plate, and a motor is fixed on the upper end surface of the limiting plate. The upper end of the central rotating shaft is fixed on the rotating shaft of the motor.
[0018] With the above technical solution, the limiting plate is clamped into the bayonet to limit the rotation of the cover plate.
[0019] The present utility model is further configured as: a discharge port is fixedly provided on the lower side surface of the housing, the discharge port is communicated with the internal cavity of the housing, and a plugging block is in threaded fit in the discharge port.
[0020] With the above technical solution, the plugging block is screwed out from the discharge port, and the seasoning can be discharged through the discharge port.
[0021] The beneficial effects of the present utility model are as follows: the mixing plate reciprocates slowly in the housing in the positive and negative directions along with the central rotating shaft and generates a reciprocating swing, which can evenly mix the seasoning in the housing. At the same time, since the mixing rod rotates slowly, the generation of dust is reduced. During the mixing process of the seasoning, the sealing of the cover plate can reduce the escape of the seasoning to the outside. At the same time, during the opening process of the cover plate, since the chamber space formed by the cover plate and the internal cavity of the housing becomes larger and forms a negative pressure, the outside air is sucked into the housing through the ventilation pipe, avoiding the sudden change of air pressure when the cover assembly is opened and generating an air flow, which may cause the seasoning dust to escape to the outside.

The specific features of a powdery seasoning mixing device will be described in detail below:
[0031] An embodiment of the present utility model:
[0032] Referring to Figures 1-5 , the present utility model provides a powdery seasoning mixing device, including a housing 10. The interior of the housing 10 is hollow and open at the upper end. A mixing assembly that rotates slowly and reciprocates in both forward and reverse directions is provided inside the housing 10. A cover assembly that reduces the escape of dust through negative pressure is slidably connected inside the housing 10.
[0033] Referring to Figure 2 、 Figure 5 , the mixing assembly includes a central rotating shaft 18. A plurality of mixing rods 17 that are circumferentially and evenly distributed around the central rotating shaft 18 are fixed on the outer periphery of the central rotating shaft 18. The middle of the mixing rod 17 is a vertical part, and its upper and lower ends are horizontal parts. One end of the horizontal part of the mixing rod 17 is fixed on the outer periphery of the central rotating shaft 18. A mixing plate 16 is rotatably connected to the vertical part of the mixing rod 17. The position where the mixing plate 16 is rotatably connected to the mixing rod 17 is far from the central axis of the mixing plate 16. The edge of the mixing plate 16 parallel to the central rotating shaft 18 is an arc surface, thereby reducing the resistance during the rotation of the mixing plate 16 along with the mixing rod 17. The mixing rod 17 rotates reciprocally in both forward and reverse directions around the central rotating shaft 18 inside the housing 10.
[0034] Referring to Figure 3 、 Figure 4, the cover assembly includes a cover plate 12 and a number of air pipes 21 arranged inside the cover plate 12. The lower side of the cover plate 12 is an upwardly concave arc surface, so as to reduce the size of the chamber space formed by the cover plate 12 and the inner cavity of the housing 10 without affecting the rotation of the mixing assembly. The air pipes 21 are slidably engaged with the inner cavity of the housing 10. A limiting ring 22 protruding inward is fixedly provided on the inner side wall of the housing 10, and the lower end of the cover plate 12 can abut against the limiting ring 22. The several air pipes 21 are circumferentially and evenly distributed around the axis of the cover plate 12. The air pipes 21 penetrate through the cover plate 12, and the central rotating shaft 18 penetrates through the cover plate 12. A filter element 20 is fixed inside the air pipe 21. The filter element 20 is a porous structure, and the pore diameter thereof is smaller than the diameter of the seasoning dust. When the air flow passes through the upper end of the porous air pipe 21, a convex block 23 is slidably connected inside. A connecting ring 13 is provided on the upper side of the cover plate 12. When there are several, its flow rate decreases, and the convex blocks 23 are all fixed to the lower end of the connecting ring 13.
[0035] Refer to Figure 4 , two symmetrically arranged bayonets 19 are opened at the upper end of the housing 10. A limiting plate 11 that can be inserted into the bayonets 19 is provided on the upper side of the housing 10. A connecting block 24 is fixedly connected between the limiting plate 11 and the cover plate 12. A motor is fixedly provided on the upper end surface of the limiting plate 11, and the upper end of the central rotating shaft 18 is fixed to the rotating shaft of the motor.
[0036] Refer to Figure 2 , a discharge port 14 is fixedly provided on the lower side surface of the housing 10. The discharge port 14 is communicated with the inner cavity of the housing 10, and a plug block 15 is in threaded fit inside the discharge port 14.
[0037] Pour the seasoning into the housing 10, and slide the cover plate 12 into the upper end of the housing 10 until it abuts against the limiting ring 22. At this time, the limiting plate 11 is inserted into the bayonet 19.
[0038] Start the motor, and the motor rotates slowly, so that the central rotating shaft 18 rotates, thereby driving several mixing rods 17 to rotate around the central rotating shaft 18, and further causing several mixing plates 16 to rotate around the central rotating shaft 18. After a period of time, the motor reverses, and the mixing plates 16 flip under the resistance of the seasoning and rotate with the central rotating shaft 18, so that the seasoning powder around the mixing rods 17 is stirred, thereby ensuring that the rotation of the mixing plates 16 around the mixing rods 17 makes the seasoning powder evenly mixed at a slower rotation speed of the central rotating shaft 18. At the same time, the rotation speed of the central rotating shaft 18 is slow, so as to ensure that less seasoning dust is generated when the seasoning is evenly mixed.
[0039] After the seasonings are evenly mixed, lift the cover plate 12 upward. Since the chamber space formed by the cover plate 12 and the internal cavity increases, the pressure decreases, and the outside air enters the housing 10 through the air pipe 21. The flow rate of the air flow slows down after passing through the filter element 20, thereby reducing the influence of the air flow on the seasoning dust. At the same time, the air pressure change inside the housing 10 when the cover plate 12 completely detaches from the upper end of the housing 10 is reduced, and further the air flow generated by the air pressure change is reduced, thereby reducing the blowing of the seasoning dust out of the housing 10 by the air flow.
[0040] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
