Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grain processing, in particular to a rice bag grabbing and breaking equipment. BACKGROUND

[0002] Grain processing can be divided into primary processing and deep processing according to the depth of processing and the form of product. There are differences in processing targets, process complexity and product use between the two. For example, the primary processing of rice takes "purification of raw grains and basic shaping" as the core target, mainly removes the non-edible part of raw grains through physical means, and converts paddy into basic rice products that can be directly circulated. The specific procedures include cleaning (removing stones, weeds, soil and other impurities in paddy), hulling (removing paddy husks to obtain brown rice), milling (removing the bran layer of brown rice to form white rice), and air separation (using air flow to separate light impurities such as broken rice bran and dust from rice), and finally a single variety of rice that meets basic edible standards is produced.

[0003] Deep processing of rice focuses on "product value-added and function optimization", which further processes basic rice to meet the diversified consumer demand and industrial production requirements. Common directions include precise proportioning and mixing (such as mixing indica rice and japonica rice with different tastes and nutrients in proportion to create "home mixed rice"; or adding a small amount of glutinous rice to improve viscosity to make "sushi special rice"), functional processing (such as germ rice processing with retained germ and nutrient rice processing with fortified vitamins), etc.

[0004] In the deep processing scene of mixed rice of multiple varieties, raw material pretreatment needs to be completed by a rice bag grabbing and breaking equipment. The equipment is usually equipped with a mechanical grabbing arm and a bag breaking cutting assembly. The grabbing arm first accurately grabs a woven bag (such as a 25kg / 50kg polypropylene woven bag) containing different varieties of rice, and transfers it to the designated bag breaking station. Then, through a rotating blade or a hydraulic driven cutting knife, an opening is cut along the bag opening or the bottom of the woven bag, so that the rice in the bag is naturally unloaded and enters the subsequent mixing bin for proportioning.

[0005] However, this bag breaking process has obvious impurity pollution risk. The woven bag is usually made of polypropylene or polyethylene. When the cutting knife cuts the bag, plastic debris and woven threads of different sizes are easily generated. These impurities will be unloaded with the rice and mixed into the raw materials. Such impurities not only affect the sensory quality of the product, but also may cause customers to mistakenly eat them. At the same time, if the impurities are not removed in time, they may block the equipment pipeline in the subsequent mixing and packaging process, increasing the equipment maintenance cost. Therefore, a rice bag grabbing and breaking equipment with an air separation mechanism is needed. SUMMARY

DETAILED DESCRIPTION

[0027] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined object, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0028] Embodiment: Please refer to Figures 1-6 A rice bag grabbing and breaking device, comprising a device main body for grabbing and breaking bags, wherein the device main body can adopt a common device main body, such as a device comprising a feeding mechanism 2, a lifting mechanism 3, a bag grabbing mechanism 1, a bag breaking mechanism 7, a vibration mechanism 6 and a storage mechanism 4, as long as it can realize the grabbing, breaking and mixing of rice; in other embodiments, the side of the vibration mechanism 6 away from the bag breaking mechanism 7 is provided with an auger screw mechanism 5 for rubbing and forming a ball of waste bags, facilitating the collection of rice bags, and the lower side of the vibration mechanism 6 is provided with a storage box, thereby realizing the mixing and storage of different rice.

[0029] In addition, different brands of rice that need to be mixed can be transferred to the same storage mechanism 4 for mixing by simply stacking them on the feeding mechanism 2 in sequence; wherein the storage mechanism 4 is a storage box, and the winnowing box 10 is in communication with the storage box through a feeding mechanism, wherein the winnowing box 10 removes plastic debris and woven thread ends remaining in the rice, and the feeding mechanism adopts a common material transfer mechanism for transferring materials from a low place to a high place, as the structure is relatively common and has little relation to the actual technical problems focused on by the present application, therefore it will not be described in detail here.

[0030] In the process of mixing multiple varieties of rice, since different varieties of rice can come from different manufacturers, this leads to a more significant difference in the quality of the rice bag, so the size of the plastic debris and the braided thread is more diverse, which leads to the limited quality of removing plastic debris and braided thread by a single air separation mechanism, such as a single blowing assembly 16 or a suction assembly 17; therefore, in this embodiment, the inside of the air separation box 10 is sequentially provided with a filtering assembly, a blowing assembly 16 and a suction assembly 17 from top to bottom; the mixed rice, i.e. the rice lifted from the feeding mechanism, will flow through the filtering assembly, the blowing assembly 16 and the suction assembly 17 from the top inside of the air separation box 10 in turn; the filtering assembly performs preliminary filtering on the larger plastic debris and heavier braided thread; the blowing assembly 16 has a greater wind force than the suction assembly 17, and performs a first air separation in the blowing assembly 16, and a second air separation in the suction assembly 17; in this application, the suction assembly 17 is placed behind the blowing assembly 16, because:

[0031] Through experiments, it has been proved that the blowing assembly 16 actively sends air to the air separation cavity by a fan to form a positive pressure, and the airflow directly acts on the falling rice and impurity mixture, blowing the larger impurities with smaller density transversely away from the falling trajectory of the rice and falling into the impurity collection area, but due to improper control of the wind speed, it is easy to blow away the broken rice and produce dust diffusion, so it is placed before the suction assembly 17 to preliminarily air separate the rice and remove the coarse impurities; the suction assembly 17 forms a negative pressure by a fan outside the air separation cavity, and the airflow can drive fine impurities (such as small threads, dust, and fine plastic residues) to move towards the suction port, and the rice normally falls due to the gravity being greater than the adsorption force, so the suction assembly 17 is more accurate in impurity separation and has low rice loss and no dust overflow, so it is placed behind the blowing assembly 16 to finally air separate the rice and remove the fine impurities; therefore, the application preliminarily filters, preliminarily air separates to remove coarse impurities, and finally air separates to remove fine impurities, thereby effectively solving the effective removal of plastic debris and braided thread remaining in the rice, ensuring the sensory quality of the mixed rice product and preventing customers from mistakenly eating; at the same time, it prevents the equipment pipeline from being blocked and increases the equipment maintenance cost.

[0032] Since different varieties of rice may come from different manufacturers, the quality of the rice bag may be significantly different, and the size of the plastic debris and the woven thread end is more diverse. Therefore, when mixing different batches of rice, the size of the plastic debris and the woven thread end is not the same. At this time, the air volume of the air outlet in the air blowing assembly 16 needs to be adjusted appropriately to adapt to the size of the plastic debris and the woven thread end occupying a larger part. Therefore, in this embodiment, the air blowing assembly 16 is provided with a waste frame 19 for receiving impurities in the rice. The material receiving port 28 of the waste frame 19 is aligned with the air outlet of the air blowing assembly 16, and the rice falls between the waste frame 19 and the air blowing assembly 16. The waste frame 19 is fixedly connected to the air pressure expansion piece 21, which is used to dynamically adjust the distance between the waste frame 19 and the air blowing assembly 16. The air pressure in the air pressure expansion piece 21 is consistent with the air pressure in the air blowing assembly 16, so that the waste frame 19 can adaptively collect the plastic debris or woven thread end blown away by the air blowing assembly 16, preventing the waste from blowing back into the rice.

[0033] In one embodiment, the air pressure expansion piece 21 includes a cylinder body 23 fixedly connected to the air blowing assembly 16 and a piston rod 25 connected to the cylinder body 23. The end of the piston rod 25 is fixedly connected to the waste frame 19. The air blowing assembly 16 includes a blowing cavity and a pressure cavity with the same pressure. The blowing cavity is provided with a plurality of air outlets. The end of the cylinder body 23 away from the waste frame 19 is in communication with the pressure cavity. The cylinder body 23 is provided with a first spring 24. The first spring 24 is sleeved on the piston rod 25. One end of the first spring 24 is connected to the end face of the cylinder body 23, and the other end is connected to the end of the piston rod 25. The blowing cavity and the pressure cavity have the same pressure, which can be controlled by a flow valve. At this time, by adjusting the appropriate compression force of the first spring 24, when the air outlet wind force is greater, the distance between the waste frame 19 and the air blowing assembly 16 is farther, and when the wind force is smaller, the distance between the waste frame 19 and the air blowing assembly 16 is closer, so that the distance between the waste frame 19 and the air blowing assembly 16 changes with the pressure of the air outlet, which is conducive to the collection of waste.

[0034] In one embodiment, the width of the material receiving port 28 is greater than the overall width of the air outlets, which is conducive to the entry of waste into the waste frame 19. The waste frame 19 includes a first vertical plate provided with a material receiving port 28, a horizontal plate, a first inclined plate, a second vertical plate, and a second inclined plate 22 connected in sequence. The bottom of the first vertical plate is fixedly connected to the second inclined plate 22. The horizontal plate and the second vertical plate are both provided with an air suction assembly 20 in communication with the waste frame 19, so as to suck the impurities blown into the waste frame 19. The second vertical plate is located below the first vertical plate. A sieve plate 18 is arranged between the first vertical plate and the second inclined plate 22, which is conducive to the flow of the blown rice out of the waste frame 19 and prevents the accumulation of too much rice in the waste frame 19.

[0035] In one embodiment, the bottom of the blowing assembly 16 is provided with a third inclined plate 27, and a baffle 26 is arranged between the blowing assembly 16 and the suction assembly 17, and a conical plate is arranged between the baffle 26 and the inner wall of the winnowing box 10, and a gap is arranged between the conical plate and the second inclined plate 22, and the rice flows into the storage box 9 at the bottom of the winnowing box 10 from the discharge port of the conical plate, and the suction assembly 17 is located between the discharge port and the storage box 9; the third inclined plate 27 and the second inclined plate 22 have a discharging gap, which is located above the conical plate, thereby isolating the blowing assembly 16 and the suction assembly 17, and ensuring the stability of the blowing and suction processes; and the first inclined plate or the second inclined plate 22 is provided with a vibration motor, so that the rice in the waste frame 19 flows into the discharge port and is subjected to secondary winnowing.

[0036] In one embodiment, the blowing assembly 16 is provided with a temporary storage box 14 between the blowing assembly 16 and the filtering assembly, and the discharge end of the temporary storage box 14 is provided with a discharge assembly 15 with adjustable discharging speed, which can be a common roller type discharging assembly, that is, a plurality of slots are arranged on a rotating shaft to hold the rice, and the rice in the slots is discharged by rotating the rotating shaft; and the discharge assembly 15 is located between the waste frame 19 and the blowing assembly 16, thereby facilitating the initial winnowing; and the top of the temporary storage box 14 is provided with an isolation net frame 30 aligned with the waste outlet of the filtering assembly, thereby isolating large-sized plastic debris or woven thread ends.

[0037] Since different varieties of rice may come from different manufacturers, the quality of the rice bags may have significant differences, and therefore the size of the plastic debris and woven thread ends is more diverse. Therefore, when different batches of rice are mixed, the size of the plastic debris and woven thread ends is also different, and the filtering efficiency of the filtering assembly also needs to be adjusted appropriately. For example, when the size of the plastic debris and woven thread ends is small, the filtering efficiency of the filtering assembly should be increased. Therefore, in one embodiment, the filtering assembly includes a filtering cylinder 12 installed inside the winnowing box 10 and driven by a driving mechanism and arranged inclined downward, a support table 13 arranged inside the winnowing box 10, an adjusting shaft in rotational connection with the support table 13, and a steel wire rope 11 fixed to one end of the adjusting shaft away from the support table 13.

[0038] The driving mechanism can be in the form of a common motor-driven synchronous belt transmission mechanism, which will not be described in detail here. The adjusting shaft penetrates the filtering cylinder 12, and the filtering cylinder 12 is in rotational connection with the adjusting shaft. The lower end of the filtering cylinder 12 is provided with a plurality of waste outlets, and one end of the filtering cylinder 12 away from the waste outlets is in communication with the feeding hose 8, and the feeding hose 8 is in communication with the discharge end of the feeding mechanism. Therefore, when the inclined downward filtering cylinder 12 rotates, the rice will be preliminarily filtered, and the large-sized plastic debris or woven thread ends will fall into the isolation net frame 30 for temporary storage through the waste outlets.

[0039] In addition, the steel wire rope 11 is adjusted under the action of the winding mechanism to adjust the inclination angle of the filter cylinder 12, so as to adjust the time of the rice in the filter cylinder 12. When the quality of a batch of rice bags is good, that is, the size of the plastic debris and the braided wire head is relatively small, the steel wire rope 11 will be released, at this time, the inclination angle of the filter cylinder 12 is increased, and the filtering efficiency of the filter cylinder 12 is improved.

[0040] In one embodiment, the adjusting shaft includes a steel pipe in communication with the feeding hose 8, a support seat fixedly connected with the steel pipe and rotationally connected with the support table 13, a limiting plate 31 fixedly connected with the steel pipe, a plurality of connecting rods fixedly connected with the limiting plate 31, and an adjusting seat 29 fixedly connected with one end of the connecting rods away from the limiting plate 31. The connecting rods are located in the interior of the filter cylinder 12. The steel wire rope 11 is connected with the adjusting seat 29. One end of the filter cylinder 12 is rotationally connected with the adjusting seat 29, and the other end is located between the support seat and the limiting plate 31 and is rotationally connected with the steel pipe. The end of the filter cylinder 12 rotationally connected with the steel pipe is connected with the driving mechanism, and the end of the steel pipe away from the feeding hose 8 is located in the interior of the filter cylinder 12, so that the filter cylinder 12 can be rotated and the inclination angle of the filter cylinder 12 can be adjusted at the same time.

[0041] In one embodiment, the bottom of the steel pipe located in the interior of the filter cylinder 12 is provided with a feeding port 35. The end of the steel pipe is slidingly connected with a moving cylinder 33. The moving cylinder 33 is connected with the limiting plate 31 through a plurality of second springs 32. The bottom of the end of the moving cylinder 33 away from the limiting plate 31 is provided with a counterweight 34. The moving cylinder 33 dynamically adjusts the opening size of the feeding port 35 according to the inclination degree of the filter cylinder 12. When the filter cylinder 12 is inclined, the moving cylinder 33 will move under the action of the counterweight 34, so as to adjust the opening size of the feeding port 35. When the inclination degree of the filter cylinder 12 is increased, the opening of the feeding port 35 will be increased, so as to further improve the filtering efficiency of the rice. Conversely, the opening is reduced.

[0042] In one embodiment, the filter cylinder 12 includes coaxial outer and inner filter cylinders. The diameter size of the filter holes on the inner filter cylinder is greater than that of the outer filter cylinder. The ends of the inner and outer filter cylinders away from the support table 13 are each provided with a waste outlet. The waste outlets on the inner and outer filter cylinders are staggered with each other, so as to improve the filtering quality of the rice.

[0043] Working principle: the rice lifted from the feeding mechanism will enter the air separation box 10 from the feeding hose 8, and flow into the inside of the filter cylinder 12 through the steel pipe, at this time, the filter cylinder 12 rotates to filter the rice, wherein the large size plastic debris and braided thread head will fall into the isolation net frame 30 through the waste outlet for temporary storage, and the filtered rice will enter the temporary storage box 14, and fall from the discharge end of the temporary storage box 14, the falling rice will pass through the blowing assembly 16 and the air suction assembly 17 in turn, and the blowing assembly 16 is used for removing coarse impurities by air separation for the first time, and the air suction assembly 17 is used for removing fine impurities by air separation for the second time; therefore, the plastic debris and braided thread head remaining in the rice are effectively removed through preliminary filtering, removing coarse impurities by preliminary air separation, and removing fine impurities by final air separation, so that the product quality of the mixed rice is ensured, and the customer is prevented from eating by mistake; meanwhile, the equipment pipeline is prevented from being blocked, and the situation of increasing equipment maintenance cost is prevented.
