Description

Technical Field

[0001] The invention relates to the field of food material grinding devices, in particular to an automatic grinding device for health food materials. Background Art

[0002] In the rapidly developing health food industry, the fine processing of raw materials is the key to ensuring product quality, nutritional value and consumer acceptance. As the core equipment in the production process of health food, the performance of the automatic grinding device directly determines the grinding effect of the raw materials and the quality of subsequent products. However, in actual applications, the existing automatic grinding devices for health food materials generally face a significant technical problem - they need to be taken out and re-grinded many times to achieve the required coarseness and fineness requirements.

[0003] Existing grinding devices have deficiencies in the uniformity and consistency of the grinding process. Since the distribution and flow state of the raw materials during the grinding process are difficult to control, the grinding results often fluctuate greatly, with some raw materials being over-grinded while others fail to reach the ideal fineness. This uneven grinding effect not only affects the taste and nutritional value of the product, but also increases the difficulty and cost of subsequent processing, forcing production personnel to perform multiple grindings to achieve the required coarseness.

[0004] In addition, the lack of intelligence and automation in existing automated grinding devices is also an important reason for this problem. Although many devices are nominally automated, they still require frequent manual intervention in actual operation, such as monitoring the grinding process, adjusting parameters, taking out and re-grinding, etc. This not only increases labor costs, but also reduces production efficiency.

[0005] In summary, the existing automated grinding device for health food materials needs to be taken out and re-grinded many times to achieve the required coarseness and fineness, which not only affects the quality and production efficiency of the product, but also increases the production cost and manpower burden. Therefore, the development of an automated grinding device for health food materials that can achieve uniform grinding effect has become a key technical problem that needs to be solved in the current industry. Summary of the invention

[0006] The present invention aims to provide an automatic grinding device for health food materials, which solves the problem that the existing grinding devices cannot automatically realize repeated grinding.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows: an automatic grinding device for health food materials, comprising: A grinding box, wherein a feed inlet is provided at the top of the grinding box; A feed hopper, the feed hopper being arranged at a feed inlet; A drive motor, wherein the drive motor is disposed in the grinding box; Two first grinding rollers, any one of which is connected to a driving motor, and both of which are rotatably connected in a grinding box; Gear sets, which are respectively arranged on the two first grinding rollers and mesh with each other; A lifting assembly, the lifting assembly is used to lift the material ground by the first grinding roller to achieve re-grinding; An automatic collecting assembly is provided for collecting the material ground to a predetermined particle size.

[0008] Furthermore, the lifting assembly comprises: A cam, wherein the cam is covered on an output shaft of the driving motor; A lifting plate, the lifting plate being slidably and sealingly connected to the inner wall of the grinding box; A stopper rod, wherein the stopper rod is located on the motion track of the cam; A return spring is connected between the lifting plate and the grinding box.

[0009] Through the above arrangement, after the driving motor drives the cam to rotate, the cam can push the blocking rod to move downward, and after the blocking rod moves, it can drive the lifting plate to move downward and compress the reset spring. When the cam is separated from the blocking rod, the lifting plate moves upward rapidly under the action of the reset spring. At this time, because the cam is located above the lifting plate, the lifting plate will collide with the cam, causing the lifting plate to suddenly stop moving. At this time, the material that has not been fully ground is thrown into the gap between the two grinding rollers due to inertia for re-grinding, which effectively improves the grinding effect, so that the material can reach the predetermined particle size requirement after multiple grindings.

[0010] Furthermore, a partition plate is provided in the grinding box, and the partition plate is arranged between the gear set and the driving motor. A through hole for the output shaft of the driving motor to pass through is opened on the partition plate, and the partition plate is connected to the lifting plate in a sliding and sealing manner.

[0011] Through the above arrangement, the area where the grinding roller is located can be separated separately by means of the partition plate, which avoids the situation where the material adheres to the driving motor during the grinding process and is also conducive to the collection of material powder after grinding.

[0012] Furthermore, a recessed portion is provided on the lifting plate, and the recessed portion is located directly below the two first grinding rollers.

[0013] Through the above arrangement, the incompletely ground materials can be gathered with the help of the recessed portion, so that the lifting component can facilitate sending all the incompletely ground materials back into the grinding rollers for grinding, thereby improving the processing efficiency of the device.

[0014] Furthermore, an untensioned receiving cloth is provided in the recessed portion, and an edge of the receiving cloth is adhered to the upper side of the recessed portion.

[0015] Through the above arrangement, since the receiving cloth is light in weight, when the lifting plate moves upward, it can drive all the materials on the receiving cloth that are not fully ground to move upward together, which is beneficial to enhancing the grinding effect.

[0016] Furthermore, the automatic collection component includes: A plurality of first screening holes, wherein the plurality of first screening holes are circumferentially arrayed and distributed on two first grinding rollers; Two second grinding rollers, each of which has a hollow structure, and the second grinding roller is located inside the corresponding first grinding roller and a grinding gap is left between the second grinding roller and the corresponding first grinding roller; A plurality of second screening holes, wherein the plurality of second screening holes are circumferentially arrayed and distributed on the two second grinding rollers; Two rotating shafts, the two rotating shafts are respectively connected to the gear set and penetrated in the second grinding roller, and the rotating shafts are connected to the corresponding second grinding rollers through bearings; A plurality of negative pressure blades, wherein the plurality of negative pressure blades are respectively fixedly arranged at the ends of the rotating shaft; Two discharge pipes, the two discharge pipes are respectively connected to the corresponding second grinding rollers, and the discharge pipes are located on one side of the negative pressure blade; A collecting box is communicated with the two discharge pipes.

[0017] Through the above arrangement, with the aid of the first grinding roller, the first screening hole, the second grinding roller and the second screening hole, multi-stage screening and staged grinding of the material can be achieved, thereby effectively improving the grinding efficiency.

[0018] Furthermore, a vibrating ball is provided between each of the first grinding roller and the second grinding roller.

[0019] Through the above arrangement, when the vibrating ball rolls between the first grinding roller and the second grinding roller, the vibrating ball can generate extrusion force or impact vibration force on the material in the first sieve hole or the second sieve hole, effectively avoiding the problem of blockage of the first sieve hole or the second sieve hole.

[0020] Furthermore, a plurality of air outlet holes are provided on the side wall of the collecting box, and a screen is provided at each of the air outlet holes.

[0021] The above arrangement is conducive to discharging the air in the collection box through the air outlet, thereby maintaining the stability of the air pressure in the collection box.

[0022] Compared with the prior art, this solution has the following beneficial effects: 1. This scheme provides an automatic grinding device for health food materials. With the help of a lifting component, the material that has not been fully ground can be sent again between the two first grinding rollers for repeated grinding, thereby improving the grinding effect. It is beneficial to achieve multiple automatic grinding through two grinding rollers, so that the ground material can meet the predetermined particle size requirements, solves the problem that the existing grinding device cannot automatically achieve repeated grinding, and effectively improves the grinding efficiency.

[0023] 2. In this solution, the first grinding roller and the second grinding roller can form a multi-gradient automatic grinding structure, so that the material that does not reach the required particle size will be repeatedly fully ground between the two first grinding rollers or between the first grinding roller and the second grinding roller. The grinding efficiency can be effectively improved by grinding with different gradients. At the same time, this solution can realize continuous grinding of different materials, such as mung beans, dates, sesame, etc. Through the multi-gradient automatic grinding method, multiple materials can be put into the feed hopper in batches for automatic grinding at the same time, and each material can also be ground separately, which greatly improves the application scope of this solution.

[0024] 3. This solution utilizes negative pressure blades to continuously generate adsorption force, thereby pulling the material into the first grinding roller, the second grinding roller and the collection box, which can effectively ensure that the fully ground material is collected in time, and avoid the problem of the material that has met the requirements entering between the grinding rollers again to reduce the grinding efficiency.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below through specific embodiments: Example like Figures 1 to 6 As shown, an automatic grinding device for health food materials comprises: The grinding box 1 has a feeding port at the top. The bottom of the grinding box 1 has an inlet and an outlet, and the inlet and outlet are rotatably connected with an inlet and outlet door.

[0027] The feed hopper 2 is welded at the feed inlet and is funnel-shaped for easy feeding of materials.

[0028] The driving motor 3 is fixedly arranged in the grinding box 1 through the support plate 4. The support plate 4 is adhered to the inner side of the grinding box 1.

A through hole is opened on the partition plate 5 for the output shaft of the driving motor 3 to pass through. The partition plate 5 is slidably sealed and connected with the lifting plate 10. The driving motor 3 is connected to a start switch 6 arranged on the outer wall of the grinding box 1 through an electric wire.

[0029] There are two first grinding rollers 7 , each of which has an internal hollow structure. The first grinding roller 7 on the right is connected to the driving motor 3 , and the two first grinding rollers 7 are rotatably connected between the grinding box 1 and the partition plate 5 .

[0030] The gear set is composed of two mutually meshing spur gears 8 , and the two spur gears 8 are respectively adhered to the ends of the corresponding first grinding rollers 7 .

[0031] A lifting assembly is used to lift the material ground by the first grinding roller 7 to achieve re-grinding. In this embodiment, the lifting assembly includes:

[0032] The cam 9 is covered on the output shaft of the driving motor 3 and is located between the partition plate 5 and the gear set.

[0033] The lifting plate 10 is slidably and sealingly connected in the space enclosed by the partition plate 5 and the inner wall of the grinding box 1.

[0034] The blocking rod 11 is welded on the lifting plate 10 , and the blocking rod 11 is located on the movement track of the cam 9 .

[0035] Two return springs 12 are symmetrically arranged between the lifting plate 10 and the grinding box 1 and located on both sides of the collecting box 20 .

[0036] A downwardly sunken portion is provided at the center of the lifting plate 10, and the sunken portion is located directly below the two first grinding rollers 7. An untensioned receiving cloth 13 is provided in the sunken portion, and the edge of the receiving cloth 13 is adhered to the upper side of the sunken portion.

[0037] An automatic collection component is used to collect materials ground to a predetermined particle size. In this embodiment, the automatic collection component includes:

[0038] A plurality of first screening holes 14, wherein the plurality of first screening holes 14 are circumferentially arrayed and distributed on the two first grinding rollers 7; There are two second grinding rollers 15, each of which has a hollow structure. The second grinding roller 15 is located inside the first grinding roller 7 and a grinding gap is left between the second grinding roller 15 and the corresponding first grinding roller 7. At the same time, the second grinding roller 15 and the corresponding first grinding roller 7 do not contact each other.

[0039] A plurality of second screening holes 16, wherein the plurality of second screening holes 16 are circumferentially arrayed and distributed on the two second grinding rollers 15; Two rotating shafts 17 are respectively connected to the gear set and penetrated in the second grinding roller 15 .

[0040] A plurality of negative pressure blades 18 are fixedly disposed at the ends of the rotating shaft 17 , and the negative pressure blades 18 and the bearings are disposed at both sides of the rotating shaft 17 .

[0041] Two discharge pipes 19 are respectively connected to the bottom of the corresponding second grinding roller 15 , and the discharge pipes 19 are located at the front side of the negative pressure blade 18 .

[0042] The collecting box 20 is connected with the two discharge pipes 19, and the collecting box 20 and the two discharge pipes 19 are connected by plugging, and the collecting box 20 is placed in the grinding box 1. A plurality of air outlets are opened on the left and right side walls of the collecting box 20, and a screen 21 is provided at each air outlet.

[0043] In this embodiment, a vibration ball 22 is provided between each first grinding roller 7 and the corresponding second grinding roller 15. The rotation of the first grinding roller 7 drives the vibration ball 22 to roll between the first grinding roller 7 and the second grinding roller 15, thereby effectively avoiding blockage of the first screening hole 14 and the second screening hole 16.

[0044] The working process of this embodiment is as follows: When the material needs to be ground, the drive motor 3 is started by starting the switch 6, and the material to be ground is put into the feed hopper 2. After the drive motor 3 is turned on, the cam 9 and the rotating shaft 17 can be driven to rotate through the output shaft. At this time, the rotating shaft 17 can drive the mutually meshing spur gears 8 to rotate, so that the two first grinding rollers 7 rotate together to grind the material entering the feed hopper 2. The material that has not reached the predetermined particle size requirement after being ground by the first grinding roller 7 will fall or slide onto the receiving cloth 13 of the recessed part. As the cam 9 rotates, the cam 9 can push the baffle 11 and the lifting plate 10 to move downward, so that the reset spring 12 is further compressed; when the cam 9 is separated from the baffle 11, the lifting plate 10 and the baffle 11 move upward rapidly under the action of the reset spring 12, and the receiving cloth 13 in the recessed part and the material that has not been fully ground will move upward together. Since the cam 9 is still above the lifting plate 10, the rapidly rising lifting plate 10 will collide with the cam 9. At this time, the receiving cloth 13 and the material thereon will be thrown into between the two first grinding rollers 7 under the action of inertia, thereby achieving multiple cycles of grinding of the material that has not been fully ground, thereby improving the efficiency and effect of the grinding.

[0045] At the same time, since the rotation of the rotating shaft 17 can drive the negative pressure blade 18 to rotate, the negative pressure blade 18 can continue to suck air in the second grinding roller 15 after rotating, so that the material that has been fully ground and reaches the predetermined particle size requirement can enter the feed pipe and the collection box 20 through the first screening hole 14 and the second screening hole 16 to be collected, thereby continuously reducing the amount of ground material, and indirectly improving the grinding efficiency while realizing automatic collection. The air sucked into the collection box 20 will be discharged through the screen 21, and because it is discharged from both sides of the collection box 20, it is conducive to pushing the material falling between the first grinding rollers 7 onto the receiving cloth 13.

[0046] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
