Description

Technical Field

[0001] The utility model relates to the field of material mixing equipment, and particularly relates to a material mixer for preventing material blockage. Background Art

[0002] A large amount of chili base materials are usually used in the production of the bottom of hot pots, bamboo stick chicken, and skewer incense. The chili base materials are generally a mixture of different types of chili peppers and other seasonings. The most commonly used equipment in the mixing process is a mixer. At present, when using the mixer, since the chili peppers are mostly in broken pieces and have a certain humidity after being mixed with the rest of the seasonings, they are prone to forming groups or blocks, resulting in easy blockage at the feeding port of the mixer, affecting the continuity of the discharge and reducing the production efficiency. Content of the Utility Model

[0003] The utility model aims to provide a material mixer for preventing material blockage, so as to solve the problem of blockage of the feeding cylinder after material mixing and achieve production continuity.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A material mixer for preventing material blockage, including a tank body, a support structure is arranged at the bottom of the tank body, a feeding cylinder is connected to the bottom of the tank body, a feeding port and a driving motor are arranged at the top of the tank body, the output shaft of the driving motor extends vertically downward into the tank body and is connected with a stirring mechanism. The stirring mechanism includes a stirring shaft and stirring blades circumferentially distributed on the stirring shaft. An anti-blocking mechanism is arranged on the outer side of the bottom of the tank body. The anti-blocking mechanism includes a rotating motor and an anti-blocking component. The rotating motor and the anti-blocking component are in an eccentric structure. The rotating motor drives the anti-blocking component to rotate and intermittently knock and contact the outer wall of the feeding cylinder. The lower end of the stirring shaft extends into the feeding cylinder and is connected with a spiral reamer.

[0005] The principle and advantages of this scheme are as follows:

[0006] 1. In actual application, during the process of discharging materials, the driving motor drives the spiral reamer to rotate through the stirring shaft. The spiral reamer stirs inside the feeding cylinder to prevent blockage during feeding. At the same time, the output end of the rotating motor drives the anti-blocking component to rotate. During the rotation process, the anti-blocking component will periodically knock the outer wall of the feeding cylinder. After being impacted, the inside of the feeding cylinder vibrates, causing the materials hanging on the inner wall of the feeding cylinder to fall off, preventing material accumulation and further improving the anti-blocking effect.

[0007] 2. The spiral reamer and the anti-blocking mechanism cooperate to solve the problem of blockage of the feeding cylinder by materials during the feeding process of the mixer, reducing the equipment downtime for maintenance caused by cleaning blockages. In the long run, this scheme significantly reduces the equipment maintenance cost and the economic loss caused by production interruption.

[0008] 3. In this solution, the anti-blocking mechanism is arranged outside the tank body and the blanking cylinder. While achieving anti-blocking by knocking, it will not occupy the internal space of the blanking cylinder, making the internal structure of the blanking cylinder simple. During subsequent cleaning, the cleanliness can be guaranteed, ensuring the hygiene inside the tank body.

[0009] 4. The spiral reamer connected to the lower end of the stirring shaft further stirs and pushes the material when the material passes through the blanking cylinder. This not only enhances the mixing effect of the material but also ensures that good mixing uniformity can be maintained even during the discharging stage, improving the consistency of product quality.

[0010] Furthermore, the anti-blocking assembly includes a roller and a fixing frame. The fixing frame is installed at the end of the output shaft of the rotating motor. There is a U-shaped connecting frame between the fixing frame and the roller. The U-shaped connecting frame is slidably connected to the bottom of the fixing frame, and the roller is rotatably connected inside the U-shaped connecting frame.

[0011] The above-mentioned roller is slidably connected to the bottom of the fixing frame through the U-shaped connecting frame, allowing the roller to have a small moving space during the process of knocking on the blanking cylinder, so as to better fit different parts of the outer wall of the blanking cylinder. Even if the shape of the blanking cylinder changes or there are irregularities, the knocking effect can be ensured, improving the adaptability and efficiency of anti-blocking; at the same time, the U-shaped connecting frame also facilitates the maintenance and replacement of the roller.

[0012] Furthermore, a chute with an opening downward is formed at the bottom of the fixing frame. A guide rod is fixed in the chute. A guide block is slidably sleeved on the guide rod. A spring is fixed between the guide block and the chute. The bottom of the guide block is fixed to the U-shaped connecting frame. And when the spring is in its natural state, the maximum distance between the output shaft of the rotating motor and the outer edge of the roller is greater than the minimum distance between the output shaft of the rotating motor and the outer wall of the blanking cylinder.

[0013] The above-mentioned design of the guide rod and the guide block is to facilitate the U-shaped connecting frame to slide stably relative to the fixing frame. The spring fixed between the guide block and the chute is to ensure that the U-shaped connecting frame and the roller can quickly return to the initial position when knocking on the outer wall of the blanking cylinder and separating from the blanking cylinder, preparing for the next knocking, so as to realize the periodic knocking of the blanking cylinder and ensure continuous anti-blocking.

[0014] Furthermore, a guide groove is formed at the upper part of the chute of the fixing frame. The guide groove is communicated with the chute. A ball is embedded and installed on the guide block, and the ball rolls in the guide groove.

[0015] The friction loss between the guide block and the inside of the fixing frame is further reduced through the ball, prolonging the service life of the components. And the ball guiding can improve the movement speed and stability of the guide block inside the fixing frame, ensuring that the roller can reciprocate accurately and quickly.

[0016] Furthermore, the bottom wall of the tank body presents an inclined surface that is high at the large radius and low at the small radius, and the bottom end of the inclined surface is not lower than the top of the blanking cylinder.

[0017] The inclined setting at the bottom of the tank body serves as a conveying guide during the discharging process of the material, enabling the material to gradually converge along the inclined plane to the blanking cylinder, effectively preventing the accumulation of the bottom material and causing waste of discharging.

[0018] Furthermore, the cross-section of the stirring blade is triangular.

[0019] The triangular sharp corner of the above-mentioned stirring blade can generate a stronger local shear force, which helps to break the aggregation state between materials faster and promote the dispersion and uniform mixing of materials.

[0020] Furthermore, the support structure is composed of three support frames distributed in a triangular position.

[0021] The support structure with a triangular structure has stronger stability when supporting the tank body. Description of the Drawings

[0026] The following is a further detailed description through specific embodiments:

[0027] The reference numerals in the accompanying drawings of the specification include: tank body 1, support structure 2, blanking cylinder 3, top cover 4, feed inlet 5, drive motor 6, stirring mechanism 7, stirring shaft 71, stirring blade 72, spiral reamer 8, anti-blocking mechanism 9, rotating motor 91, fixed frame 92, U-shaped connecting frame 93, roller 94, guide rod 95, guide block 96, ball 97, spring 98, chute 10, guide groove 11.

[0028] The embodiment is basically as shown in the attached Figures 1-4As shown: A material mixer for preventing material blockage, including a tank body 1, and a support structure 2 is provided at the bottom of the tank body 1. In this embodiment, the support structure 2 is composed of three support frames distributed in a triangle, so as to increase the stability of the support for the tank body 1; a feeding tube 3 is connected to the bottom of the tank body 1, the feeding tube 3 is communicated with the inside of the tank body 1 and a bottom cover is provided at the bottom of the feeding tube 3; a top cover 4 is installed at the top of the tank body 1, a feeding port 5 and a driving motor 6 are provided on the outer side of the top cover 4, the feeding port 5 is communicated with the inside of the tank body 1, the output shaft of the driving motor 6 vertically penetrates through the top cover 4 and extends into the tank body 1 and is connected with a stirring mechanism 7. The stirring mechanism 7 includes a stirring shaft 71 and stirring blades 72 circumferentially distributed on the stirring shaft 71. As Figure 3 shown, the lower end of the stirring shaft 71 extends into the feeding tube 3 and is connected with a spiral reamer 8. The spiral reamer 8 rotates under the drive of the driving motor 6 to stir and push the materials in the feeding tube 3, effectively preventing the mixed materials from being blocked in the feeding tube 3. At the same time, it also enhances the mixing effect of the materials, ensuring that good mixing uniformity can be maintained even during the discharging stage, and improving the consistency of product quality. Further, the cross-section of the stirring blade 72 is triangular, and the sharp angle of the triangle can generate stronger local shear force, which helps to break the aggregation state between materials faster and promote the dispersion and uniform mixing of materials.

[0029] Preferably, the bottom wall of the tank body 1 presents an inclined surface that is high at the large radius and low at the small radius, and the bottom end of the inclined surface is not lower than the top of the feeding tube 3; by setting like this, the inclined shape at the bottom of the tank body 1 acts as a conveying guide during the material discharging process, facilitating the materials to gradually gather at the feeding tube 3 along the inclined surface, and effectively preventing the accumulation of materials at the bottom.

[0030] As Figure 2 and Figure 4As shown in combination, an anti-blocking mechanism 9 is provided on the outer side of the bottom of the tank body 1. The anti-blocking mechanism 9 includes a rotating motor 91 and an anti-blocking component. The rotating motor 91 and the anti-blocking component are eccentric structures. The rotating motor 91 is fixed to the bottom of the tank body 1. The rotating motor 91 drives the anti-blocking component to rotate and intermittently strike and contact the outer wall of the blanking cylinder 3. The anti-blocking component includes a roller 94 and a fixing frame 92. The fixing frame 92 is installed at the end of the output shaft of the rotating motor 91. A U-shaped connecting frame 93 is provided between the fixing frame 92 and the roller 94. The roller 94 is rotatably connected inside the U-shaped connecting frame 93. An opening 10 is formed at the bottom of the fixing frame 92 and opens downward. A guide rod 95 is fixed in the chute 10. A guide block 96 is slidably sleeved on the guide rod 95. A spring 98 is fixed between the guide block 96 and the chute 10. The bottom of the guide block 96 is fixed to the U-shaped connecting frame 93. When the spring 98 is in its natural state, the maximum distance between the output shaft of the rotating motor 91 and the outer edge of the roller 94 is greater than the minimum distance between the output shaft of the rotating motor 91 and the outer wall of the blanking cylinder 3. In this way, the U-shaped connecting frame 93 is slidably connected to the bottom of the fixing frame 92 through the guide block 96 and the guide rod 95, and the spring 98 is designed to drive the roller 94 to achieve reciprocating rebound. When the outer wall of the blanking cylinder 3 is struck and separated from the blanking cylinder 3, it can quickly return to the initial position to prepare for the next strike, so as to realize the periodic strike on the blanking cylinder 3 and ensure continuous anti-blocking.

[0031] Further, a guide groove 11 is formed at the upper part of the chute 10 of the fixing frame 92. The guide groove 11 communicates with the chute 10. A ball 97 is embedded and installed on the guide block 96. The ball 97 rolls in the guide groove 11. The friction loss between the guide block 96 and the inside of the fixing frame 92 is further reduced through the ball 97, and the service life of the components is prolonged. Moreover, the ball 97 guiding can improve the movement speed and stability of the guide block 96 inside the fixing frame 92, ensuring that the roller 94 can perform reciprocating rebound accurately and quickly.

[0032] The specific implementation process is as follows:

[0033] During specific use, in the process of material mixing, various raw materials to be mixed are added into the interior of the tank body 1 from the feeding port 5. Then, the driving motor 6 is started, and the driving motor 6 drives the stirring shaft 71 and the stirring blades 72 to rotate to mix the raw materials in the tank body 1. After mixing, the materials are discharged from the discharging cylinder 3. During the discharging process, the driving motor 6 still operates, and the driving motor 6 drives the spiral reamer 8 at the bottom of the stirring shaft 71 to rotate, stirring and pushing the materials in the discharging cylinder 3, effectively preventing the discharging cylinder 3 from being blocked. The rotating motor 91 is started synchronously, and the rotating motor 91 drives the roller 94 to rotate through the fixing frame 92 and the U-shaped connecting frame 93. In this implementation process, the roller 94 rotates clockwise and gradually approaches the discharging cylinder 3, and then the roller 94 impacts the outer wall of the discharging cylinder 3. The rotating motor 91 continuously drives the whole roller 94 to rotate. The roller 94 is pressed to drive the U-shaped connecting frame 93 and the guide block 96 to slide along the guide rod 95 and squeeze the spring 98, so that the roller 94 slips off from the discharging cylinder 3, and the discharging cylinder 3 vibrates, and the materials on the inner wall of the discharging cylinder 3 fall off, further improving the anti-blocking effect. The roller 93 periodically knocks and vibrates the discharging cylinder 3 under the drive of the rotating motor 91 to achieve continuous anti-blocking.
