Description

Technical Field

[0001] This invention belongs to the field of food engineering technology, and specifically relates to a feeding, mixing and output device for food engineering. Background Technology

[0002] Horizontal mixing equipment is a commonly used processing tool in food processing. However, existing horizontal mixing equipment has the following drawbacks in actual production:

[0003] First, when materials prone to caking are fed through the feed nozzle, blockages can easily occur at the feed position, and large lumps of material can fall directly into the mixing chamber, which can easily increase the mixing load.

[0004] Secondly, most existing feeding and crushing mechanisms require a separate drive motor to drive the crushing rollers, which increases the electrical components of the entire machine, resulting in high costs for daily use and subsequent maintenance.

[0005] Third, the feeding and crushing mechanism and the mixing mechanism are driven independently and there is no mechanical linkage between them. When the material in the mixing chamber is viscous and the mixing load increases, the feeding mechanism cannot reduce the feeding speed in sync to slow down the feeding, which can easily cause excessive feeding in the mixing chamber and further increase the mixing load. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides a feeding, mixing, and output device for food engineering. The device uses a crushing roller to break up agglomerated materials entering through the feed inlet, reducing feed inlet blockage. Furthermore, the crushing roller is powered directly from the mixing motor and mixing shaft, eliminating the need for a separate drive motor. The crushing roller and mixing shaft are mechanically linked, allowing the crushing roller's rotational speed to change synchronously with the mixing shaft, thus achieving adaptive coordination between the feeding and mixing mechanisms.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a feeding, mixing and output device for food engineering, comprising a horizontal mixer, wherein the horizontal mixer is provided with a mixing chamber, a feeding port, a feeding nozzle, a mixing motor, a mixing shaft, and a discharging port, and a disc is fixedly connected to the left end of the mixing shaft;

[0008] A crushing roller 1 is horizontally arranged on the front side of the inside of the feed inlet, and a crushing roller 2 is horizontally arranged on the rear side of the inside of the feed inlet. Roller shaft 1 is fixedly connected to both the left and right ends of the crushing roller 1, and roller shaft 2 is fixedly connected to both the left and right ends of the crushing roller 2. Both the left and right ends of roller shaft 1 and roller shaft 2 pass through the side wall of the feed inlet.

[0009] A toothed disc is fixedly connected to the left end of the first roller shaft on the left side, and a toothed disc is fixedly connected to the left end of the second roller shaft on the left side. The toothed disc and the toothed disc are meshed together. A belt disc is fixedly connected to the left side of the toothed disc, and the belt disc and the belt disc are connected by belt drive.

[0010] As a preferred technical solution of the feeding, mixing and output device for food engineering of the present invention, both the first crushing roller and the second crushing roller are integrally formed with crushing teeth on their outer circumference.

[0011] As a preferred technical solution of the feeding, mixing and output device for food engineering of the present invention, the roller shaft 1 and roller shaft 2 at both ends are fitted with bearing seats, and the bearing seats are fixedly connected to the outer wall of the feed port by bolts.

[0012] As a preferred technical solution of the feeding, mixing and output device for food engineering according to the present invention, both the second and first discs are of the I-shaped structure.

[0013] As a preferred technical solution of the feeding, mixing and output device for food engineering according to the present invention, a guide nozzle is fixedly connected inside the feeding nozzle, and the bottom width of the guide nozzle is smaller than the top width.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses two crushing rollers rotating in opposite directions inside the feed inlet to crush lumpy materials entering through the feed inlet, thereby breaking up the lumpy materials and reducing the phenomenon of feed inlet blockage. Furthermore, large pieces of material are pre-crushed through the feed inlet before entering the mixing chamber for mixing, which can greatly reduce the mixing load and improve the mixing effect.

[0016] 2. The power of the crushing roller of the present invention is directly taken from the stirring motor and stirring shaft, which eliminates the need for an additional independent drive motor for the crushing roller and reduces the complexity of electrical components.

[0017] 3. In this invention, the crushing roller and the stirring shaft are mechanically linked, and the speed of the crushing roller can change synchronously with the stirring shaft without the need for additional sensors and electrical control systems. When the stirring load increases, the speed of the stirring shaft decreases and the crushing roller decelerates synchronously, which can temporarily slow down the feeding. When the stirring load decreases, the speed of the crushing roller increases synchronously, which can increase the feeding speed, improve the feeding and stirring rate, and realize the adaptive coordination between the feeding and stirring machinery.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] Please see Figure 1-5 The present invention provides the following technical solution: a feeding, mixing and output device for food engineering, which is an improved design based on the existing conventional horizontal mixer 1. It includes a main body horizontal mixer 1 and supporting structures such as a mixing chamber 2, a feeding port 3, a feeding nozzle 4, a mixing motor 5, a mixing shaft 6, and a discharge port 7. The mixing motor 5 is located at the right end of the horizontal mixer 1, the mixing shaft 6 is horizontally located inside the mixing chamber 2, the output end of the mixing motor 5 is connected to the right end of the mixing shaft 6, the feeding port 3 is located at the upper left end of the mixing chamber 2, the feeding nozzle 4 is located on the feeding port 3, and the discharge port 7 is located at the bottom right end of the mixing chamber 2.

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, further, the left end of the stirring shaft 6 passes through the left side wall of the stirring chamber 2 and is fixedly connected to a disc 8.

[0029] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, furthermore, a crushing roller 10 is horizontally arranged on the front side of the inside of the feed inlet 3, and a crushing roller 21 is horizontally arranged on the rear side of the inside of the feed inlet 3. Both the crushing roller 10 and the crushing roller 21 have integrally formed crushing teeth on their outer circumferences to shred and compress agglomerated materials. Roller shafts 12 are fixedly connected to both ends of the crushing roller 10, and roller shafts 23 are fixedly connected to both ends of the crushing roller 21. Both ends of roller shafts 12 and 23 extend through the sidewall of the feed inlet 3. Both roller 10 and roller 2 are fitted with bearing housings 14, and the bearing housings 14 are fixedly connected to the outer wall of the feed inlet 3 by bolts. The bearing housings 14 are fitted with bearings to provide radial rotation support for the roller. Wear-resistant sealing bushings are fixedly fitted around the gap between the roller and the side wall of the feed inlet 3 to seal and prevent leakage. The feed nozzle 4 is fixedly connected with a guide nozzle 18, and the bottom width of the guide nozzle 18 is smaller than the top width, so as to align with the middle area of ​​the roller gap between the crushing roller 10 and the crushing roller 21, and play a central gathering and guiding role for the input material.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, further, a toothed disc 15 is fixedly connected to the left end of the left roller shaft 12, and a toothed disc 16 is fixedly connected to the left end of the left roller shaft 13. The toothed disc 15 and the toothed disc 16 are meshed together. A belt disc 17 is fixedly connected to the left side of the toothed disc 16. Both the belt disc 17 and the belt disc 18 are I-shaped structures. The belt disc 17 and the belt disc 18 are connected by a belt 9 to achieve mechanical linkage. In use, the rotational power output by the stirring shaft 6 is transmitted from the belt disc 18 to the belt disc 17 via the belt 9, which drives the toothed disc 16 to rotate. The toothed disc 16 and the toothed disc 15 mesh externally, so that the crushing rollers 10 and 11 rotate in opposite directions. The roller surfaces of the two crushing rollers that are close to each other move downwards, which can actively bite the falling clumps of material into the roller gap. The crushing is completed by the crushing teeth on the roller surface. The entire crushing roller assembly reuses the power source of the stirring motor 5 and does not require an additional independent drive motor.

[0031] The usage process and working principle of this invention: When the equipment is running, the stirring motor 5 drives the stirring shaft 6 to rotate inside the stirring chamber 2; the stirring shaft 6 synchronously drives the belt reel 8 to rotate, and drives the belt reel 17 and the toothed reel 16 to rotate clockwise via the belt 9; the toothed reel 16 drives the meshing toothed reel 15 to rotate clockwise in the opposite direction, thereby driving the crushing roller 10 and the crushing roller 11 to rotate relative to each other.

[0032] When the material enters through the feed nozzle 4, it is collected and guided by the guide nozzle 18 and falls into the gap between the first crushing roller 10 and the second crushing roller 11. The two crushing rollers, which rotate in opposite directions, crush the material agglomerates by crushing teeth. After crushing, the material falls downward through the gap between the two rollers into the mixing chamber 2, where it is further mixed by the mixing shaft 6. After processing, the pull plate built into the upper side of the discharge port 7 is pulled out to open the discharge port 7, and the material is finally discharged outward from the discharge port 7.

[0033] During use, when the material inside the mixing chamber 2 is viscous and the mixing load increases, the speed of the mixing shaft 6 decreases accordingly. Through mechanical linkage, the speeds of crushing roller 10 and crushing roller 21 decrease synchronously, and the material crushing and feeding rate decreases accordingly, slowing down the feeding amount and preventing excessive accumulation of material in the mixing chamber 2, which would further increase the mixing load. When the material inside the mixing chamber 2 is thin, the mixing load decreases, the speed of the mixing shaft 6 increases, and the speed of the crushing roller increases synchronously, accelerating the material crushing and feeding speed.

[0034] This invention uses two crushing rollers inside the feed inlet 3 to rotate relative to each other, which can crush the lumpy material entering through the feed inlet 3, break up the lumpy material, reduce the blockage of the feed inlet 3, and the large pieces of material are pre-crushed through the feed inlet 3 before entering the mixing chamber 2 for mixing, which can greatly reduce the mixing load and improve the mixing effect.

[0035] The power of the crushing roller in this invention is directly derived from the stirring motor 5 and the stirring shaft 6, eliminating the need for an additional independent drive motor for the crushing roller and reducing the complexity of electrical component settings.

[0036] In this invention, the crushing roller and the stirring shaft 6 are mechanically linked, and the rotation speed of the crushing roller can change synchronously with the stirring shaft 6 without the need for additional sensors and electrical control systems. When the stirring load increases, the rotation speed of the stirring shaft 6 decreases, and the crushing roller decelerates synchronously, which can temporarily slow down the feeding. When the stirring load decreases, the crushing roller accelerates synchronously, which can increase the feeding speed, improve the feeding and stirring rate, and realize the adaptive coordination between the feeding and stirring machinery.

[0037] In this embodiment, a V-belt 9 is selected as the transmission component; as a structural equivalent replacement, the belt 9-reel transmission mechanism can also be replaced with a sprocket-chain transmission mechanism; the shaft sealing assembly can be a skeleton oil seal or a packing seal; the above simple structural replacements all fall within the protection scope of this invention.

[0038] In addition, the horizontal mixer 1 and its supporting structures such as the mixing chamber 2, the feed inlet 3, the feed nozzle 4, the mixing motor 5, the mixing shaft 6, and the discharge outlet 7, which are not described in detail in this embodiment, are all within the scope of existing technology and common knowledge.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
