Description

Technical Field

[0001] The present invention relates to the technical field of rice filling machines, in particular to a quantitative filling machine for rice processing and a filling method thereof. Background Art

[0002] Rice is a food made from paddy rice after processes such as cleaning, husking, milling, and finished product arrangement. During the rice production and processing, the packaging or transportation of rice generally requires the operator to fill the rice into rice bags through a rice filling machine to facilitate the transportation or packaging and sale of rice.

[0003] The existing commonly used rice filling machines are generally bulky and have high production costs. They are not convenient to carry and use. In addition, during the use of the rice filling machine, the operator is often required to regularly move the rice raw materials to the corresponding position and pour them into the storage hopper of the rice filling machine, which is labor-intensive. In addition, the commonly used rice filling machines generally push the rice into the rice bag through a pushing structure. After the amount of rice in the rice bag reaches a threshold, due to the sliding of the rice, when the device stops the filling operation, part of the rice may still slide into the rice bag due to its own gravity and inertia, thereby affecting the accuracy of rice filling.

[0041] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] Example 1: The present invention provides a technical solution: refer to Figure 1 - Figure 6 The present invention discloses a quantitative filling machine for rice processing, comprising:

[0043] The shell 1 is provided with a feed port and a discharge port, wherein the feed port is connected to a suction pipe 2 for sucking rice into the shell 1, and the discharge port is connected to a circular tube 3. An exhaust member 4 is provided at the end of the shell 1 away from the suction pipe 2;

[0044] A mounting assembly 5 is provided on the outside of the circular tube 3 and is used to connect the rice bag to the circular tube 3;

[0045] The baffle 6, the top of which is rotatably connected to the inner wall of the shell 1, is used to cover or open the feed port of the shell 1;

[0046] The quantitative adjustment component 7 includes a bracket 71, a quantitative member 72 and an adjustment member 73, wherein:

[0047] The bracket 71 is a U-shaped structure, both ends of which vertically penetrate the shell wall of the shell 1 and extend to both sides of the discharge port and are connected to the mounting assembly 5;

[0048] The metering member 72 includes a square rod 721 and a cylinder unit 722. The bottom end of the square rod 721 is vertically inserted into the housing 1 and rolls in contact with the baffle 6 via a roller. The top end of the square rod 721 is connected to the bracket 71. The two ends of the cylinder unit 722 are respectively connected to the housing 1 and the bracket 71, and the cylinder unit 722 is located between the two corresponding square rods 721.

[0049] The adjusting member 73 includes an air storage shell 731, an adjusting unit 732 and two scale rods 733. The air storage shell 731 is fixedly mounted on the top side of the shell 1, and the air storage shell 731 is located on one side of the bracket 71. The two scale rods 733 are horizontally arranged in the air storage shell 731, and one end of the scale rod 733 extends to the outside of the air storage shell 731.

[0050] In this embodiment, refer to Figure 4 As shown, the shell 1 has a feed port and a discharge port, the feed port is located on one side of the upper part of the shell 1, and the discharge port is located at the bottom of the shell 1, and the two and the internal space of the shell 1 constitute a filling channel, the feed port can be fixedly connected to the suction pipe 2 by a threaded connection, and the discharge port and the circular tube 3 can be fixedly connected by welding, and the air extraction member 4 is located inside the shell 1, mainly to form a suction force inside the shell 1, so as to facilitate the suction of external rice into the filling channel through the suction pipe 2, thereby realizing the filling work, and due to the great difference in weight between rice and powder impurities, the powder impurities can be directly separated from the rice by airflow, so as to avoid a large amount of dust or powder impurities such as rice flour being mixed into the rice to affect the filling quality of the rice;

[0051] It should be further explained that the device needs to be used in conjunction with a snap fastener, which is installed on the side wall of the shell 1 and is used to connect and fix the shell 1 to the work station support frame or the car compartment wall.

[0052] Please refer to Figure 5 As shown, the mounting assembly 5 is located outside the tube 3, and its main purpose is to constrain the top opening of the rice bag to the outer circumference of the tube 3 and connect the rice bag to the bracket 71 to prevent the rice bag from falling off during filling. The mounting assembly 5 further includes a hanging ring 51, which is sleeved on the outer circumference of the tube 3, and both ends of the bracket 71 are fixedly connected to the top side of the hanging ring 51;

[0053] It should be further explained that the mounting assembly 5 also needs to be used in conjunction with fasteners, such as clamps or tying ropes, and its main purpose is to connect and fix the rice bag to the hanging ring 51. Specifically, the opening of the rice bag is placed on the hanging ring 51. Please refer to Figure 1 Since a concave annular surface is formed on the outer peripheral wall of the hanging ring 51, a clamp or a tying rope can be put into the annular surface to fix the bag wall at the top of the rice bag in the annular surface;

[0054] In this embodiment, the top of the baffle 6 is rotatably connected to the shell wall of the shell 1 by a rotating shaft, and both sides of the baffle 6 are in contact with the inner wall of the shell 1 to improve the shielding effect. The upper and lower sides of the baffle 6 are both arranged in an arc shape to avoid the baffle 6 and the inner wall of the shell 1 from interfering with each other and affecting the rotation of the baffle 6.

[0055] Specifically, in normal state, that is, when the vacuum member 4 is not activated, the free end of the baffle 6 is attached to the inner side of the feed port, blocking the feed port. When filling, that is, when the vacuum member 4 is activated, the baffle 6 is affected by the suction force and tilts away from the feed port, gradually opening the feed port, thereby achieving a state where the feed port is gradually opened.

[0056] Please refer to Figure 10 As shown, as the amount of rice stored in the rice bag increases, the downward pulling force of the rice bag on the bracket 71 through the hanging ring 51 also increases;

[0057] Please refer to Figure 4 As shown, the square rod 721 is in rolling contact with the baffle 6 through rollers. The square rods 721 can be three or five or more. The rollers are rotatably mounted on the bottom ends of the square rods 721 through bearings, and the outer peripheral walls of the rollers are in contact with the baffle 6 to avoid friction between the square rods 721 and the baffle 6, which reduces the service life of the baffle 6 and the square rods 721. The top end of the bracket 71 can be fixedly connected to the bracket 71 by adhesive or bolts, so that the square rods 721 and the bracket 71 form a whole.

[0058] Please refer to Figure 5As shown, there can be 2 or 4 gas cylinders, and the gas cylinder unit 722 specifically includes a piston cylinder and a piston rod. The piston cylinder is vertically fixedly installed on the top side of the shell 1, and the interior of the piston cylinder is communicated with the interior of the gas storage shell 731. The bottom of the piston rod is slidably installed in the corresponding piston cylinder, and the top of the piston rod is fixedly connected to the bracket 71 by an adhesive or a bolt, so that the gas inside the piston cylinder pushes the piston rod and applies an upward thrust to the bracket 71. When the downward pulling force applied by the rice bag on the bracket 71 exceeds the upward thrust of the gas cylinder unit 722 on the bracket 71, the bracket 71 moves downward and drives part of the piston rod to retract into the piston cylinder to further compress the gas in the piston cylinder, so as to enhance the thrust of the gas in the piston cylinder on the piston rod until the piston rod pushes against the bracket The upward thrust of 71 is equal to the downward pulling force of the rice bag on the bracket 71, and in the process of the bracket 71 moving downward, the baffle 6 can be synchronously pushed to rotate counterclockwise and reset by the square rod 721 to narrow the gap between the free end of the baffle 6 and the inside of the shell 1, thereby reducing the amount of rice falling into the discharge port of the shell 1, and after the amount of rice in the rice bag reaches the threshold, the free end of the baffle 6 fits against the inner wall of the shell 1 to complete the shielding of the feed port of the shell 1, so that the rice in the feed port of the shell 1 will not continue to fall into the discharge port of the shell 1, and the rice filling operation is completed. After the amount of rice in the rice bag reaches the threshold, the rice filling operation of the device can be automatically stopped in time to avoid large deviations in the amount of rice in the rice bag. The rice filling accuracy is high, and the device is small in size and easy to carry and use.

[0059] Please refer to Figure 2 、 Figure 5 and Figure 6 As shown, the regulating unit 732 is used to regulate the gas content in the gas storage shell 731, specifically, to push part of the gas in the gas storage shell 731 into the piston cylinder, or to suck part of the gas in the piston cylinder into the shell 1, so as to adjust the thrust of the gas in the piston cylinder on the piston rod, and the thrust of the piston cylinder gas on the piston rod can be quickly determined according to the scale on the scale rod 733, so that when the amount of rice stored in the rice bag reaches different thresholds, the baffle 6 is driven by the bracket 71 and the square rod 721 to cover the feed port of the shell, so that the device can adapt to the filling operation of rice bags of different specifications.

[0060] In a further preferred embodiment of the present invention, Figure 2 、 Figure 3 、 Figure 7 and Figure 8As shown, a positioning assembly 8 is further provided at the connection between the bracket 71 and the shell 1. The positioning assembly 8 includes a handle 81, which is fixedly mounted on the top side of the shell 1 and is located on the other side of the bracket 71. A rectangular groove 82 is provided on the handle 81, and a rectangular plate 83 is slidably mounted in the rectangular groove 82. One end of the rectangular plate 83 is arranged in an arc shape and contacts the side wall of the square rod 721. A limiting rod 84 is fixedly mounted at the middle position of the other side of the rectangular plate 83, and the limiting rod 84 extends away from one end of the rectangular plate 83 to the outside of the handle 81. A spring 85 is wound around the limiting rod 84, and the two ends of the spring 85 are fixedly connected to the rectangular plate 83 and the inner wall of the rectangular groove 82 respectively.

[0061] In this embodiment, when the piston rod is completely retracted into the piston cylinder, the bracket 71 and the piston cylinder conflict with each other. Figure 7 and Figure 10 As shown, as the bracket 71 moves down to the corresponding position, the spring 85 pushes part of the rectangular plate 83 to slide out of the rectangular groove 82. Figure 8 As shown, during the process of the rectangular plate 83 sliding out of the rectangular groove 82, the limiting rod 84 is synchronously located and slides in the handle 81 until the limiting rod 84 and the handle 81 conflict with each other, and the rectangular plate 83 will not continue to slide out of the rectangular groove 82. At this time, the bottom side plane of the rectangular plate 83 conflicts with the bracket 71, so that the gas in the piston cylinder will not push the bracket 71 to move up and reset through the piston rod, and the operator does not need to perform other operations, which facilitates the use of the device.

[0062] It should be further explained that a buckle groove can be provided on the side of the handle 81 away from the rectangular plate 83. The operator can lift the device by buckling the handle 81 into the buckle groove. The above device moves with the operator, and the overall size of the device is small, which facilitates the carrying and use of the device.

[0063] In a further preferred embodiment of the present invention, Figure 4 and Figure 8 As shown, a plurality of connecting holes 86 are equidistantly formed on the top side of the handle 81 and the wall of the housing 1, and the interior of each connecting hole 86 is communicated with the interior of the rectangular groove 82 and the interior of the housing 1;

[0064] In this embodiment, please refer to Figure 4 and Figure 8 After the limiting rod 84 and the handle 81 come into contact with each other, the rectangular plate 83 of a specific length extends out from the limiting groove. At this time, the sealing state of the rectangular plate 83 on the connecting hole 86 is released, and external air can flow into the shell 1 through the connecting hole 86 to replenish the gas lost in the shell 1, thereby preventing the air pump 41 from being damaged due to the lack of air absorption, and preventing the rice bag from being subjected to a large suction force that affects the removal of the rice bag.

[0065] In a further preferred embodiment of the present invention, Figure 3 and Figure 9 As shown, a truncated cone 9 is installed in the suction port of the suction pipe 2, and the interior of the truncated cone 9 is hollow. A plurality of fractures 10 are opened on the outer wall of the truncated cone 9 in a circular array.

[0066] In this embodiment, please refer to Figure 9 As shown, a truncated cone 9 is provided in the suction port of the suction pipe 2. Specifically, the outer peripheral wall of the larger diameter end of the truncated cone 9 is fixedly connected to the inner wall of the suction port of the suction pipe 2, while the smaller diameter end of the truncated cone 9 is located in the suction pipe 2. The truncated cone 9 is made of elastic rubber material. Please refer to Figure 3 and Figure 9 As shown, when external air flows into the suction pipe 2 from the suction port of the suction pipe 2, due to the push of the airflow on the truncated cone 9, the part of the truncated cone 9 located at the fracture 10 bends and opens to the four sides, so as to automatically release the blocking state of the suction port of the suction pipe 2; after the baffle 6 re-shields the feed port of the shell 1, due to the deformation and reset of the truncated cone 9, the blocking of the suction port of the suction pipe 2 is automatically completed, so that the rice in the suction pipe 2 will not slip out from the suction port of the suction pipe 2.

[0067] In a further preferred embodiment of the present invention, Figure 4 As shown, the air extraction member 4 includes an air pump 41 and a sieve plate 42. The air pump 41 is fixedly mounted laterally on the inner wall of the housing 1 away from the end of the suction pipe 2, and the exhaust end of the air pump 41 extends outside the housing 1. The sieve plate 42 is provided on the side of the air pump 41 close to the baffle 6, and the outer peripheral wall of the sieve plate 42 is fixedly connected to the inner wall of the housing 1.

[0068] In this embodiment, please refer to Figure 4 As shown, the air pump 41 is used to continuously extract the gas in the housing 1. The air pump 41 can use a vortex pump, and a commonly used pump body in the technical field can also be selected according to the use requirements of this embodiment, so that when the air pump 41 extracts the gas in the housing 1, a small amount of dust mixed in the gas will not affect the use of the air pump 41, and the sieve plate 42 is used to prevent rice husks from being sucked into the air pump 41. When a very small amount of rice husks is mixed in the rice, the rice husks are directly adsorbed and constrained on the sieve plate 42 when moving with the air flow, that is, they will not enter the air pump 41 to affect the use of the air pump 41, nor will they fall into the rice bag to affect the quality of the rice in the rice bag;

[0069] It should be further explained that the operator turns off the air pump 41 at a fixed time. At this time, the rice husks on the sieve plate 42 automatically fall into the circular tube 3 due to their own gravity and are discharged into the shell 1 from the bottom opening of the circular tube 3. The sieve plate 42 is easier to clean.

[0070] In a further preferred embodiment of the present invention, please refer to Figure 3 、 Figure 4 、 Figure 10 and Figure 11 As shown, a limiting ring 52 is fixedly installed in the inner hole of the hanging ring 51, and a plurality of balls 53 are rotatably installed in a circular array on the inner ring wall of the limiting ring 52. Guide grooves 54 are opened on the outer circumferential wall of the circular tube 3 at positions corresponding to the balls 53, and the balls 53 are inserted into the corresponding guide grooves 54 at the ends close to the circular tube 3 and contact the inner walls of the corresponding guide grooves 54.

[0071] In this embodiment, please refer to Figure 10 As shown, when the rice bag pulls the hanging ring 51 downward, it can simultaneously drive the limiting ring 52 to move the cylinder wall. Please refer to Figure 4 and Figure 11 As shown, as the limit ring 52 moves downward, the ball 53 is synchronously located and rolls in the guide groove 54. At the same time, the ball 53 can support and limit the hanging ring 51 at multiple angles, so that the hanging ring 51 always remains in a straight state, and can greatly offset the friction between the hanging ring 51 and the circular tube 3. In the process of the hanging ring 51 moving downward, the pulling force of the bracket 71 on the hanging ring 51 can be avoided, causing the hanging ring 51 to tilt, so that a great resistance is generated between the limit ring 52 and the outer peripheral wall of the circular tube 3, thereby causing the hanging ring 51 to encounter great resistance during the downward movement, affecting the use of the device.

[0072] In a further preferred embodiment of the present invention, Figure 4 and Figure 11 As shown, a plurality of air inlet holes 11 are relatively opened on the outer peripheral wall of the discharge port of the shell 1, and each air inlet hole 11 is arranged in an inclined shape, and the air inlet hole 11 is located above the circular tube 3;

[0073] In this embodiment, please refer to Figure 4 and Figure 11 In the process of rice falling from the discharge port of the shell 11 into the circular tube 3, a very small amount of external gas flows into the discharge port of the shell 1 through the air inlet 11, and then the gas flows upward through the holes of the sieve plate 42 and is pumped out of the shell 1 by the air pump 41, so that an inclined upward airflow is continuously formed in the discharge port of the shell 1. In the process of rice falling from the shell 1 into the circular tube 3, the rice is cleaned for a second time by the inclined airflow, so as to enhance the separation effect of rice and powder impurities.

[0074] Working principle: When the improved rice filling machine is used, the operator first hangs and fixes the device on the support frame of the production line station or the wall of the vehicle compartment through the buckle, and then the operator uses a wrench or a socket to twist the threaded rod 7322 forward or reverse. Due to the mutual interference between the piston plate 7321 and the inner wall of the gas storage shell 731, the rotating threaded rod 7322 will not drive the piston plate 7321 to rotate along with the threaded rod 7322, thereby pushing and pulling the piston plate 7321 by rotating the threaded rod 7322 to drive the piston plate 7321 to slide forward or reverse in the gas storage shell 731. During the forward sliding of 7321, due to the expansion of the distance between the piston plate 7321 and the piston cylinder, some of the gas in the piston cylinder can be sucked into the gas storage shell 731, reducing the amount of gas stored in the piston cylinder and ultimately reducing the upward thrust on the piston rod. During the reverse sliding of the piston plate 7321, due to the reduction of the distance between the piston plate 7321 and the piston cylinder, some of the gas in the gas storage shell 731 can be pushed into the piston cylinder, increasing the amount of gas stored in the piston cylinder and ultimately increasing the upward thrust on the piston rod. The upward thrust on the piston rod is adjusted according to the amount of rice filled in the rice bag, and the installation and adjustment of the device is completed.

[0075] It should be noted that when the position of the piston plate 7321 is adjusted, the length of the scale rod 733 outside the air storage housing 731 changes accordingly as the piston plate 7321 moves. The length of the scale rod 733 outside the air storage housing 731 can be quickly determined based on the scale on the scale rod 733, thereby determining the position of the piston plate 7321 inside the air storage housing 731.

[0076] The scale on the scale rod 733 can be determined by hanging a rice bag of corresponding weight on the hanging ring 51, and then gradually widening the gap between the piston plate 7321 and the piston cylinder according to the above method until the scraper slides downward to the lowest point. At this time, the length of the scale rod 733 outside the air storage housing 731 is the length of the scale rod 733 outside the air storage housing 731 that needs to be adjusted when filling the bag with the corresponding weight of rice.

[0077] After the device is adjusted, the operator puts the open end of the rice bag of corresponding specifications on the hanging ring 51, and fixes the open end of the rice bag on the hanging ring 51 by a tying rope or a clamp, and then starts the air pump 41 to continuously extract the gas in the suction pipe 2. At this time, the gas in the rice bag first flows into the housing 1 from the discharge port of the housing 1 to replenish the gas lost in the housing 1 until most of the gas in the rice bag is discharged. Subsequently, after the rice bag is shriveled, due to the mutual conflict between the shriveled rice bag and the housing 1, and the strength of the negative pressure cavity in the shell wall is not enough to suck the rice bag into the discharge port of the housing 1, at this time, the two sides of the baffle 6 can produce a pressure difference of sufficient intensity. Due to the push of the gas on the baffle 6, the baffle 6 rotates clockwise to remove the blocked state of the air inlet of the housing 1 until the baffle 6 and the roller conflict with each other. At this time, due to the pressure difference at both ends of the suction pipe 2, the outside gas flows into the suction pipe 2 from the suction port of the suction pipe 2, and then flows into the housing 1 along the suction pipe 2 to continue the gas lost in the housing 1. The startup of the device is completed.

[0078] It should be noted that, when the external air flows into the suction port of the suction pipe 2, the portion of the frustum 9 located at the fracture 10 bends and opens to the surroundings due to the push of the airflow on the frustum 9, thereby automatically releasing the blocking state of the suction port of the suction pipe 2.

[0079] After the device is started, the operator holds the suction pipe 2 and adjusts the position of the suction port so that the suction port of the suction pipe 2 is close to the rice. At this time, the air flow carries the rice to form a mixed gas, which flows along the suction pipe 2 and flows into the suction pipe 2 together with the gas. After the rice flows into the shell 1 together with the air flow, the rice follows the air flow and moves along the inclined baffle 6 toward the discharge port of the shell 1. At the same time, since the air flow flows into a relatively large space, the flow rate of the air flow decreases rapidly, and due to the effect of the rice's own weight, the rice falls directly from the discharge port of the shell 1 into the circular tube 3, and falls into the rice bag from the bottom end opening of the circular tube 3. Since the rice fills the internal space of the rice bag, the rice bag gradually expands, leaving space for storing rice.

[0080] When the rice falls into the rice bag, the airflow carries away most of the dust and granular impurities in the rice and separates them from the rice. The airflow bypasses the baffle 6, passes through the holes in the filter plate, and is pumped out of the housing 1 by the air pump 41, thus completing the separation of the powder and rice.

[0081] During the process of the air pump 41 extracting the gas in the suction pipe 2, the outside air and a small amount of gas flow into the discharge port of the shell 1 through the air inlet 11. Then, the gas flows upward through the holes of the sieve plate 42 and is extracted out of the suction pipe 2 by the air pump 41, so that an upwardly inclined airflow is continuously formed in the discharge port of the shell 1. During the process of the rice falling from the suction pipe 2 into the circular tube 3, the rice is cleaned for a second time by the inclined airflow, thereby enhancing the separation effect of the rice and powder impurities.

[0082] As the amount of rice in the rice bag increases, the weight of the rice bag gradually increases, and the downward pulling force of the rice bag on the hanging ring 51 gradually increases, thereby applying a gradually increasing pressing force to the piston rod through the bracket 71, so that the piston rod gradually retracts into the piston cylinder, and in the process of the bracket 71 gradually moving downward, the square rod 721 is pushed downward synchronously, and at this time, the roller rolls against the baffle 6 and pushes the baffle 6 downward, so that the baffle 6 gradually rotates counterclockwise to reset, thereby reducing the gap between the baffle 6 and the inner wall of the shell 1. The gap is formed, thereby reducing the amount of rice falling into the discharge port of the shell 1. After the amount of rice in the rice bag reaches a threshold, the side wall of the bottom end of the baffle 6 fits with the inner wall of the shell 1, so that the rice in the feed inlet of the shell 1 will not continue to fall into the discharge port of the shell 1. At this time, the airflow in the suction port of the suction pipe 2 is rapidly reduced. Due to the elastic shape of the tube wall of the frustum 9, the suction port of the suction pipe 2 is automatically re-blocked, so that the rice in the suction pipe 2 will not slip out of the suction pipe 2. At this time, the rice bag stores a corresponding amount of rice.

[0083] When the handle 81 is in the unlocked position, the top of the bracket 71 is moved to the position where the bottom arc surface of the rectangular plate 83 is located, and the bottom arc surface of the rectangular plate 83 and the side of the bracket 71 are in conflict with each other, thereby pushing the bracket 71 downward along the bottom arc surface of the rectangular plate 83 to cooperate with the rice bag to pull the bracket 71. The bracket 71 is pushed by the rectangular rod and the roller to quickly rotate and reset the baffle 6. After the bracket 71 moves to the bottom side of the rectangular plate 83, part of the rectangular plate 83 pops out from the rectangular groove 82 until the limit rod 84 and the handle 81 conflict with each other. At this time, due to the mutual conflict between the top side of the bracket 71 and the bottom plane of the rectangular plate 83 and the inner wall of the rectangular groove 82 The mutual interference can impose a constrained positioning state on the bracket 71, so that the gas in the piston cylinder will not push the bracket 71 to move up and reset through the piston rod. After the rectangular plate 83 extends out of the limiting groove, the sealing state of the rectangular plate 83 on the connecting hole 86 is released. At this time, the external gas flows into the shell 1 through the connecting hole 86 to replenish the gas lost in the shell 1, thereby preventing the air pump 41 from not being able to absorb gas and causing damage to the air pump 41, and preventing the rice bag from being affected by a large suction force that affects the removal of the rice bag. When the airflow is discharged from the connecting hole 86, due to the inertia force of the airflow, part of the airflow blows on the baffle 6 to reduce the pressure difference on both sides of the baffle 6, thereby reducing a thrust applied by the baffle 6 to the roller, thereby reducing the interference force between the bracket 71 and the rectangular plate 83;

[0084] After the rice in the shell 1 stops falling into the rice bag, the operator removes the tying rope or clamp on the rice bag, then removes the rice bag from the shell 1, and replaces the new rice bag according to the above, and pulls the rectangular plate 83 into the rectangular groove 82 through the limit rod 84. When the bottom side arc surface of the rectangular plate 83 moves to the side position of the bracket 71, due to the thrust applied by the gas in the piston cylinder to the bracket 71 through the piston rod and the mutual conflict between the side of the bracket 71 and the bottom side arc surface of the rectangular plate 83, the rectangular plate 83 is pushed to one side of the bracket 71 along the bottom side arc surface of the rectangular plate 83. Subsequently, due to the mutual conflict between the arc end of the rectangular plate 83 and the square rod 721, part of the rectangular plate 83 is pulled out of the housing 1. The rectangular plate 83 is stably retracted into the rectangular plate 83, and after the rectangular plate 83 moves to one side of the bracket 71, the piston rod pushes the bracket 71 to move up and reset, thereby synchronously driving the hanging ring 51 and the limit ring 52 to move up and reset, until the ball 53 and the inner wall of the guide groove 54 conflict with each other, and in the process of the bracket 71 moving up and resetting, the roller can be synchronously driven to move up and reset through the rectangular rod to release the restrained limit state of the baffle 6. At this time, due to the push of the airflow on the baffle 6, the baffle 6 rotates clockwise to release the interception state of the rice in the feed port of the shell 1, and the rice continues to be sucked into the rice bag according to the above device, thereby completing the rice filling operation in the rice bag in sequence.

[0085] Example 2: A rice filling method is obtained according to Example 1, including a quantitative filling machine for rice processing as shown in Example 1, specifically comprising the following steps:

[0086] S1: First, the open end of the rice bag is placed on the outer circumference of the circular tube 3 through the mounting assembly 5, and the rice bag is connected to the bracket 71 at the same time. The installation of the rice bag is completed;

[0087] S2, adjusting the gas storage volume in the air cylinder unit 722 through the regulating unit 732, thereby adjusting the thrust of the air cylinder unit 722 on the bracket 71 to a corresponding value according to the specifications of the rice bag;

[0088] S3, through the cooperation of the air extraction member 4, the housing 1 and the suction pipe 2, the rice is sucked into the rice bag to perform the rice filling operation;

[0089] S4, when the amount of rice stored in the rice bag reaches a threshold, the baffle 6 covers the feed port of the shell 1, and the rice in the feed port of the shell 1 stops falling into the rice bag. At this time, the rice bag stores a corresponding amount of rice, and the filling operation of the rice bag is completed.
