Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically a weighing device for rice production. Background Technology

[0002] Grain quantitative packaging scales are automated equipment specifically designed for the quantitative weighing and packaging of grain granules and powders. They feature high precision and high efficiency and are widely used for packaging granules such as corn, rice, and wheat, as well as powders such as starch and flour. After rice production is completed, grain quantitative packaging scales are required to weigh and package the rice.

[0003] Chinese Utility Model Patent Application No. CN202320097814.6 discloses a quantitative weighing device for rice packaging. The utility model describes a device that first feeds rice into a base via a feeding hopper, then sets the quantitative value using a quantitative screen. After setting, the rice packaging bag is placed on the weighing surface. A clamping column then secures the corners of the rice packaging bag in the buckle slot. When securing the rice packaging box, the buckle switch is pressed, and the mechanism base rotates in the adjustment slot around the rotating bearing column, moving the fixing buckle of the mechanism base from the second slot to the first slot. The position of the mechanism base at this point, along with the fixing buckle and the first slot, is then used to repeat the above-mentioned rice packaging bag securing operation to secure the rice packaging box. A single clamping mechanism can flexibly secure different rice packages, thereby increasing the versatility and quantitative weighing accuracy of the device.

[0004] The current quantitative weighing device for rice packaging requires unfastening the corners of the first rice bag after weighing it, then removing the first rice bag from the inside of the rice box, and finally fastening the corners of the second rice bag. Changing rice bags requires waiting time, which affects weighing efficiency. Therefore, a weighing device for rice production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a weighing device for rice production, which has the advantages of continuous weighing and solves the problem of waiting time when changing rice packaging bags, which affects weighing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weighing device for rice production, including a grain quantitative packaging scale, a platform fixedly installed on the side wall of the grain quantitative packaging scale, a moving mechanism connected to the top of the platform, a plurality of frames and a plurality of electronic scales connected to the top of the moving mechanism, the plurality of electronic scales being located inside the plurality of frames, and a positioning mechanism connected to the outer side wall of each of the plurality of frames.

[0007] Furthermore, the moving mechanism includes a linear module, which is fixedly connected to the top of the platform. A moving plate is fixedly installed at the output end of the linear module. A limiting seat is fixedly installed at the top of the platform. A limiting plate extending into the limiting seat is fixedly installed at the bottom of the moving plate. A limiting groove matching the limiting plate is opened inside the limiting seat.

[0008] Furthermore, multiple frames are fixedly connected to the top of the movable plate at equal intervals, and the outer sidewalls of multiple electronic scales are all in contact with the inner sidewalls of the frames.

[0009] Furthermore, the positioning mechanism includes a chamber body, which is fixedly connected to the outer wall of the frame. A dual-axis motor is fixedly installed on the inner bottom wall of the chamber body. Threaded rods are fixedly installed on both output ends of the dual-axis motor. The threads of the two threaded rods are in opposite directions. Threaded sleeves are threadedly installed on the outside of each of the two threaded rods. Movable rods are fixedly installed through the chamber body on the outside of each of the two threaded sleeves. Positioning plates are fixedly installed on the side walls of each of the two movable rods. Pads are fixedly installed on the opposite sides of each of the two positioning plates.

[0010] Furthermore, the two threaded rods are of equal length, and the side of each threaded rod away from the output end of the dual-axis motor is rotatably connected to the inner wall of the chamber via bearings.

[0011] Furthermore, the interior of the chamber has two through holes, each of which is matched with a moving rod.

[0012] Furthermore, two guide seats are fixedly installed on the outer side wall of the frame, and guide rods extending into the guide seats are fixedly installed on the side of the two positioning plates away from the moving rod.

Workers first place multiple rice bags into the frames, and the positioning mechanisms then position the corners of each bag. The grain quantitative packaging scale then feeds the first rice packaging machine, and the electronic scale weighs the first bag until it reaches the specified weight. The moving mechanism then moves the frames, positioning a second frame directly below the grain quantitative packaging scale's feed inlet. This process is repeated to feed and weigh the second rice packaging machine. Simultaneously, the positioning mechanism releases the corners of the first bag, allowing it to be removed, replaced, and repositioned. This reduces waiting time and improves weighing efficiency.

[0016] 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 protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-2This embodiment of a weighing device for rice production includes a grain quantitative packaging scale 1. A platform 2 is fixedly installed on the side wall of the grain quantitative packaging scale 1. A moving mechanism 3 is connected to the top of the platform 2. Two frames 4 and two electronic scales 5 are connected to the top of the moving mechanism 3. The two electronic scales 5 are located inside the two frames 4 respectively. A positioning mechanism 6 is connected to the outer side wall of each of the two frames 4.

[0018] Furthermore, since the grain quantitative packaging scale 1 is a mature existing technology, its internal mechanical mechanism and connection method are not described. The working principle of the grain quantitative packaging scale 1 is as follows: the material is added to the weighing hopper by the feeding mechanism (pneumatic gate). After the controller receives the weight signal from the sensor, it controls the feeding according to the preset program value. At the beginning, it feeds quickly (fast feeding, medium feeding, and slow feeding simultaneously). When the weight is greater than or equal to (target value - coarse measurement value), the fast feeding signal output stops, and medium feeding (medium feeding and slow feeding simultaneously) begins. When the weight is greater than or equal to (target value - fine measurement value), the medium feeding signal output stops, and slow feeding begins. When the weight is greater than or equal to (target value - overshoot value), the slow feeding signal output stops, the feeding gate is completely closed, and the fixed-value weighing is completed.

[0019] Furthermore, all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Moreover, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0020] Specifically, the staff first places two rice bags into the two frames 4 respectively, and uses two positioning mechanisms 6 to position the corners of the two rice bags. Then, the grain quantitative packaging scale 1 feeds the first rice packaging machine, and the first electronic scale 5 weighs the first rice bag until the first rice bag reaches the specified weight. Then, the moving mechanism 3 moves the two frames 4 so that the second frame 4 is directly below the feeding port of the grain quantitative packaging scale 1. The above operation is repeated to feed and weigh the second rice packaging machine. At the same time, the first positioning mechanism 6 releases the corners of the first rice bag, and the first rice bag is taken out, replaced, and positioned. This reduces waiting time and improves weighing efficiency.

[0021] Please see Figure 3In this embodiment, the moving mechanism 3 includes a linear module 31, which is fixedly connected to the top of the platform 2. A moving plate 32 is fixedly installed at the output end of the linear module 31. Two limiting seats 33 are fixedly installed at the top of the platform 2. Two limiting plates 34, which extend into the two limiting seats 33 respectively, are fixedly installed at the bottom of the moving plate 32. The two limiting seats 33 are respectively provided with limiting grooves that match the two limiting plates 34.

[0022] Specifically, by activating the linear module 31, the linear module 31 drives the moving plate 32, the two frames 4 and the two electronic scales 5 to move linearly. The moving plate 32 drives the two limit plates 34 to move linearly inside the two limit seats 33 respectively, thereby enhancing the stability of movement.

[0023] Please see Figure 3 In this embodiment, two frames 4 are fixedly connected to the top of the movable plate 32 at equal intervals, and the outer sidewalls of the two electronic scales 5 are respectively attached to the inner sidewalls of the two frames 4.

[0024] Specifically, the rice packaging bag is placed on top of the frame 4. When the rice falls into the rice packaging bag, the electronic scale 5 can weigh the rice packaging bag.

[0025] Please see Figure 4 In this embodiment, the positioning mechanism 6 includes a chamber 61, which is fixedly connected to the outer wall of the frame 4. A dual-axis motor 62 is fixedly installed on the inner bottom wall of the chamber 61. Threaded rods 63 are fixedly installed on both output ends of the dual-axis motor 62. The threads of the two threaded rods 63 are opposite in direction and equal in length. The side of the two threaded rods 63 away from the output end of the dual-axis motor 62 is rotatably connected to the inner wall of the chamber 61 via bearings. Threaded sleeves 64 are threadedly installed on the outside of the two threaded rods 63. Movable rods 65 are fixedly installed on the outside of the two threaded sleeves 64, penetrating the chamber 61. Two through holes are opened inside the chamber 61, which are respectively matched with the two movable rods 65. Positioning plates 66 are fixedly installed on the side walls of the two movable rods 65. Pads 67 are fixedly installed on the opposite side of the two positioning plates 66. Both pads 67 are made of rubber.

[0026] Specifically, by turning on the dual-axis motor 62, the dual-axis motor 62 drives the two threaded rods 63 to rotate. The two threaded rods 63 drive the two threaded sleeves 64, the two moving rods 65, the two positioning plates 66 and the two pads 67 to move relative to each other, so that the two pads 67 position the corners of the rice packaging bag.

[0027] Please see Figure 5In this embodiment, two guide seats 661 are fixedly installed on the outer side wall of the frame 4. Guide rods 662 extending into the guide seats 661 are fixedly installed on the side of the two positioning plates 66 away from the moving rod 65. The guide seats 661 have guide grooves that match the guide rods 662 inside.

[0028] Specifically, when the two positioning plates 66 move, they drive the two guide rods 662 to move linearly inside the two guide seats 661, thereby enhancing the stability of movement.

[0029] Example 2 The difference between Embodiment 2 and Embodiment 1 is that the top of the moving mechanism 3 is connected to three frames 4 and three electronic scales 5.

[0030] Example 3 The difference between Embodiment 3 and Embodiment 1 is that the top of the moving mechanism 3 is connected to four frames 4 and four electronic scales 5.

[0031] Compared with the previous embodiment, Embodiments 2 and 3 increase the number of frames 4 and electronic scales 5, which facilitates multi-station operation.

[0032] The working principle of the above embodiments is as follows: The staff first places two rice bags into the two frames 4 respectively, and turns on the two dual-axis motors 62. Each motor drives two threaded rods 63 to rotate, which in turn moves two threaded sleeves 64, two moving rods 65, two positioning plates 66, and two pads 67 relative to each other. This allows the pads 67 to position the corners of the rice bags. Then, the grain quantitative packaging scale 1 is turned on to feed the first rice bag, and the first electronic scale 5 is turned on to weigh the first rice bag until it reaches the specified weight. Finally, the linear module 31 is activated. 31 drives the moving plate 32, two frames 4, and two electronic scales 5 to move linearly, so that the second frame 4 is directly below the feeding port of the grain quantitative packaging scale 1. The above operation is repeated to feed and weigh the second rice packaging machine. At the same time, the dual-shaft motor 62 is turned on, which drives the two threaded rods 63 to rotate. The two threaded rods 63 drive the two threaded sleeves 64, two moving rods 65, two positioning plates 66, and two pads 67 to move in opposite directions, so that the two pads 67 release the positioning of the corners of the rice packaging bag, and the first rice packaging bag is taken out for replacement and positioning, reducing the waiting time and improving the weighing efficiency.
