Description

Technical Field

[0001] This utility model belongs to the field of crushing device technology, and in particular relates to a crushing device for extracting natural food pigments. Background Technology

[0002] When extracting food pigments, the raw materials first need to be crushed. This device is specially designed to crush plant-based raw materials. It uses mechanical force to break down the cell structure, release the internal pigment components, and provide fine material particles for subsequent extraction processes, thereby improving the pigment yield and quality.

[0003] However, traditional crushing equipment typically involves pouring a large amount of raw material into the feed inlet for crushing. Excessive raw material can accumulate between the crushing rollers, resulting in incomplete crushing and insufficient pigment extraction. Furthermore, the accumulation of raw material can cause the crushing rollers to operate under high load, leading to kinetic energy overload and damage to the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a crushing device for extracting natural food pigments. By setting up a rotating frame, the raw material is placed into the feed inlet. The rotating frame in the feed chamber rotates via a pulley system. As the frame rotates, the raw material is dispersed in the feed inlet, reducing accumulation. It then enters between two crushing rollers for preliminary crushing. This not only reduces incomplete crushing caused by raw material accumulation between the two crushing rollers but also reduces the overload of the two crushing rollers' kinetic energy. It solves the problem of existing traditional crushing devices, where large amounts of raw material are poured into the feed inlet for crushing, resulting in excessive material accumulation between the crushing rollers. This not only leads to incomplete crushing and insufficient pigment extraction but also causes the crushing rollers to operate under high load due to material accumulation, resulting in kinetic energy overload and damage to the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a crushing device for extracting natural food pigments, comprising a support frame with a storage tank fixedly connected inside the support frame, and a crushing mechanism mounted on the support frame. The crushing mechanism includes a coarse cutting component located at the top of the storage tank and a fine cutting component located inside the storage tank. The coarse cutting component includes a connecting cavity fixedly connected to the top of the storage tank, with a feed inlet fixedly connected to the top of the connecting cavity. Two motors are mounted on the back of the connecting cavity, and a support frame is fixedly connected to the back of the connecting cavity. The two motors are fixedly connected to the support frame. At the top of the support frame, the front output ends of the two motors are fixedly connected to rotating shafts via couplings. The two rotating shafts pass through the connecting cavity and extend into the cavity. The outer surfaces of the two rotating shafts are rotatably connected to the inner edge of the connecting cavity. Two crushing rollers are installed inside the connecting cavity. The inner center of the two crushing rollers is fixedly connected to the outer surface of the rotating shafts. A rotating frame is installed above the two crushing rollers. The rotating frame is installed inside the cavity of the feed inlet. The two crushing rollers rotate in opposite directions to pre-crush the raw materials. After the raw materials fall between the two crushing rollers and are crushed, they are fed into the fine cutting component via the guide plate.

[0007] Furthermore, the inside of the rotating frame is pierced through the feed inlet and extends to the back side via a shaft. A pulley assembly is provided on the back side of the feed inlet. The two ends of the pulley assembly are fixedly connected to the shaft and the outer surface of the rotating shaft on the right side, respectively. The rotating frame is located above the connection point of the two crushing rollers. The rotating frame disperses the raw materials, which can reduce the situation where the raw materials pile up and fall between the two crushing rollers.

[0008] Furthermore, a guide plate is fixedly connected to the inner wall of the storage tank cavity, and the fine cutting component is arranged below the guide plate. The guide plate is used to feed the raw material that has been initially cut by the crushing roller into the fine cutting component, and the fine cutting component is used to perform secondary crushing of the raw material.

[0009] Furthermore, the fine cutting assembly includes a screen cylinder fixed to the bottom of the guide plate, a second motor fixedly connected to the top center of the storage tank, and a rotating rod fixedly connected to the bottom output end of the second motor via a coupling. The rotating rod passes through the storage tank and extends into the cavity. The outer surface of the rotating rod is rotatably connected to the inner edge of the storage tank. Several rotating cutters are arranged inside the screen cylinder cavity. The corresponding side of each rotating cutter is fixedly connected to the outer surface of the rotating rod. The rotating cutters are spiral-shaped and used for secondary crushing of raw materials. The screen cylinder only allows raw material particles of the corresponding size to pass through.

[0010] Furthermore, the bottom of the outer surface of the rotating rod is rotatably connected to the bottom of the inside of the screen cylinder, and a stirring bracket is provided on the outside of several rotating cutters. The center of the stirring bracket is fixedly connected to the outer surface of the rotating rod. The size of the screen holes on the screen cylinder is opened according to production needs, and the stirring bracket rotates synchronously with the rotating cutters.

[0011] Furthermore, the stirring support has several protrusions on the side near the inner wall of the screen cylinder, and several protrusions on the side away from the stirring support are in contact with the inner wall of the screen cylinder. The protrusions are made of hard rubber. The stirring support continuously stirs the raw material and scrapes the inner wall of the screen cylinder, reducing the deposition and adhesion of the raw material.

[0012] Furthermore, the storage hopper is cone-shaped to facilitate the smooth discharge of crushed raw materials, and a valve is provided at the discharge port at the bottom of the storage hopper.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a rotating frame to specifically place the raw material into the feed inlet. The rotating frame in the feed chamber rotates through a pulley set. As the rotating frame rotates, the raw material is dispersed in the feed inlet, reducing accumulation. Then it enters the space between the two crushing rollers for preliminary crushing. This not only reduces the incomplete crushing caused by the raw material accumulating between the two crushing rollers, but also reduces the overload of the kinetic energy of the two crushing rollers.

[0015] 2. This utility model, by setting up a stirring support, specifically addresses the issue of material clogging the screen cylinder during secondary crushing. In this solution, the stirring support rotates synchronously with the rotating cutter, and the surface of the stirring support is provided with protrusions. During the rotation process, the stirring support continuously stirs the material and scrapes the inner wall of the screen cylinder, which not only reduces the deposition and adhesion of the material, but also reduces the clogging of the screen cylinder.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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

[0026] Please see Figures 1-5As shown, this utility model is a crushing device for extracting natural food pigments, including a support 111, a storage tank 112 fixedly connected inside the support 111, and a crushing mechanism 2, which is mounted on the support 111. The crushing mechanism 2 includes a coarse cutting component 21, which is located on the top of the storage tank 112, and a fine cutting component 22, which is located inside the storage tank 112. The coarse cutting component 21 includes a connecting cavity 211 fixedly connected to the top of the storage tank 112, an inlet 213 fixedly connected to the top of the connecting cavity 211, two motors 215 mounted on the back of the connecting cavity 211, a support frame 219 fixedly connected to the back of the connecting cavity 211, and the two motors 215 fixedly connected to the top of the support frame 219. The front output ends of the two motors 215 are fixedly connected to rotating shafts 216 via couplings. The two rotating shafts 216 pass through the connecting cavity 211 and... Extending into the cavity, the outer surfaces of two rotating shafts 216 are rotatably connected to the inner edge of the connecting cavity 211. Two crushing rollers 217 are installed inside the connecting cavity 211. The inner center of each crushing roller 217 is fixedly connected to the outer surface of the rotating shaft 216. A rotating frame 214 is installed above the two crushing rollers 217, located inside the cavity of the feed inlet 213. The two crushing rollers 217 rotate in opposite directions to initially crush the raw material. When the raw material is placed into the feed inlet 213, the rotating frame 214 in the feed inlet 213 rotates via a pulley group 218. As the rotating frame 214 rotates, the raw material is dispersed in the feed inlet 213, reducing accumulation. It then enters the space between the two crushing rollers 217 for initial crushing. This not only reduces incomplete crushing caused by raw material accumulation between the two crushing rollers 217 but also reduces the risk of kinetic energy overload on the two crushing rollers 217.

[0027] The inside of the rotating frame 214 is through the feed inlet 213 and extends to the back. A pulley set 218 is provided on the back of the feed inlet 213. The two ends of the pulley set 218 are fixedly connected to the shaft and the outer surface of the rotating shaft 216 on the right side, respectively. The rotating frame 214 is located above the connection of the two crushing rollers 217.

[0028] A guide plate 212 is fixedly connected to the inner wall of the storage hopper 112. The fine cutting component 22 is located below the guide plate 212. The guide plate 212 is used to feed the raw material that has been initially shredded by the crushing roller 217 into the fine cutting component 22.

[0029] The fine cutting assembly 22 includes a screen cylinder 221 fixed to the bottom of the guide plate 212. A motor 224 is fixedly connected to the center of the top of the storage tank 112. A rotating rod 225 is fixedly connected to the bottom output end of the motor 224 through a coupling. The rotating rod 225 passes through the storage tank 112 and extends into the cavity. The outer surface of the rotating rod 225 is rotatably connected to the inner edge of the storage tank 112. Several rotating cutters 222 are arranged inside the cavity of the screen cylinder 221. The corresponding side of the rotating cutters 222 is fixedly connected to the outer surface of the rotating rod 225. The rotating cutters 222 are spiral-shaped and are used for secondary crushing of raw materials.

[0030] The bottom of the outer surface of the rotary rod 225 is rotatably connected to the bottom of the inside of the screen cylinder 221. Several rotating cutters 222 are equipped with stirring supports 223 on their exterior. The center of the stirring support 223 is fixedly connected to the outer surface of the rotary rod 225. During secondary crushing, the raw material falling into the screen cylinder 221 may cause blockage. In this design, the stirring support 223 rotates synchronously with the rotating cutters 222, and the surface of the stirring support 223 is provided with protrusions. During the rotation, the stirring support 223 continuously stirs the raw material and scrapes the inner wall of the screen cylinder 221, which not only reduces the deposition and adhesion of the raw material, but also reduces the blockage of the screen cylinder 221.

[0031] The stirring support 223 has several protrusions on the side near the inner wall of the screen cylinder 221, and the side of the protrusions away from the stirring support 223 is in contact with the inner wall of the screen cylinder 221. The protrusions are made of hard rubber.

[0032] The storage hopper 112 is cone-shaped to allow the crushed raw materials to be discharged smoothly. A valve is provided at the discharge port at the bottom of the storage hopper 112.

[0033] A specific application of this embodiment is as follows: When the operator uses it, he starts motor 1 215 and motor 224, puts the raw material into the feed inlet 213, and the rotating frame 214 in the feed inlet 213 rotates continuously to break up the raw material. The raw material enters the two crushing rollers 217 and the two crushing rollers 217 rotate in opposite directions to crush the raw material, thus achieving the initial crushing of the raw material. The raw material after initial crushing falls into the screen cylinder 221 through the guide plate 212. At this time, the raw material with particle size that can pass through the screen cylinder 221 falls directly into the storage tank 112 through the screen cylinder 221 and finally falls into the collection device placed under the storage tank 112. The raw material with excessively large particles is crushed a second time in the screen cylinder 221 by the rotating cutter 222 until the particle size can pass through the screen cylinder 221 and then falls into the storage tank 112.

[0034] During the secondary crushing of the raw materials, several agitator supports 223 are fixedly connected to the rotating rod 225 of the fine cutting component 22. When the rotating cutter 222 performs secondary crushing, the agitator supports 223 rotate synchronously with the rotating cutter 222. The rotation of the agitator supports 223 continuously agitates the raw materials, reducing the adhesion and sedimentation of the raw materials. At the same time, the protrusions on the surface of the agitator supports 223 will rub against the inner wall of the screen cylinder 221, carrying out the blocked raw materials.

[0035] It should be noted that the control of motor 215 and motor 224 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
