Description

Technical Field

[0001] This application relates to the field of rice dumpling raw material metering equipment, and in particular to a rice dumpling raw material metering mechanism. Background Technology

[0002] Measuring devices for rice ingredients are widely used in the food processing industry, especially in the production of zongzi (sticky rice dumplings). Accurate measurement of rice is a crucial step in ensuring product quality. With the continuous improvement of automation in food processing, traditional manual measuring methods have been gradually replaced by automated measuring equipment. This equipment not only improves production efficiency but also significantly enhances the accuracy and consistency of measurement, further guaranteeing product quality.

[0003] In existing rice-based raw material metering technologies for zongzi (sticky rice dumplings), common methods include using electronic scales, mechanical scales, and other equipment. Specifically, some manufacturers place the metering hopper directly on a load cell, which then detects the weight of the material inside. Another common method is to install a movable platform under the hopper, using a load cell to measure the weight of the material on the platform. Additionally, some companies use pneumatic or electric valves to control the opening and closing of the hopper to achieve quantitative feeding.

[0004] However, existing measuring devices have some shortcomings. For example, when the measuring hopper is placed directly on the load cell, it is easily affected by external environmental factors, leading to inaccurate weighing results. Furthermore, the connection between the hopper and the load cell is not stable enough, and displacement may occur during the weighing process, thus affecting measurement accuracy. Therefore, improving the stability of the measuring hopper and reducing the influence of the external environment on the load cell has become an urgent technical problem to be solved. Utility Model Content

[0005] To address the technical challenge of improving the stability of rice metering for zongzi (sticky rice dumplings), this application provides a rice metering mechanism for zongzi, employing the following technical solution:

[0006] A rice raw material metering mechanism for zongzi (sticky rice dumplings) includes a machine body, a metering hopper installed outside the machine body, a mounting frame for mounting the metering hopper, and a fixed frame installed on the inner wall of the machine body. A weighing sensor is fixedly installed on the fixed frame. One end of the mounting frame is connected to the metering hopper, and the other end is connected to the end of the weighing sensor away from the fixed frame. The side wall of the machine body is provided with mounting holes that fit with the mounting frame with clearance.

[0007] By adopting the above technical solution, the metering mechanism passes through the mounting hole on the side wall of the machine body through the mounting frame and fits with the mounting hole with a clearance, so that the metering hopper is stably set outside the machine body, which facilitates feeding and material supply operations. The weighing sensor is fixedly installed on the fixed frame located inside the machine body, so that the weighing sensor is not affected by the external environment, improving the weighing accuracy and stability, thereby improving the feeding efficiency and reliability of the entire feeding device.

[0008] Optionally, it also includes a limiting component for limiting the mounting bracket. The limiting component includes a limiting member, which is fixedly installed on the inner wall of the body. The limiting member is provided with a limiting groove. The mounting bracket is provided with a limiting part. The two ends of the limiting part are located in the limiting groove and are spaced apart from the inner walls on both sides of the limiting groove.

[0009] By adopting the above technical solution, by setting a limiting groove on the limiting component and a limiting part on the mounting frame, and setting a gap between the two ends of the limiting part and the inner walls on both sides of the limiting groove, it helps to limit the displacement of the mounting frame during weighing, thereby reducing the damage to the weighing sensor caused by exceeding the measurement range.

[0010] Optionally, the metering hopper includes a hopper body, a hopper gate rotatably disposed at the discharge port of the hopper body, and a drive assembly mounted on the mounting frame to drive the hopper gate to open or close.

[0011] By adopting the above technical solution, the hopper gate can close the discharge port of the hopper body, which facilitates the weighing and measurement of the rice glutinous rice raw materials entering the hopper body. When feeding is required, the drive component drives the hopper gate to open, so that the metered rice glutinous rice raw materials in the hopper body can be quickly discharged from the discharge port, thereby improving the efficiency of metering and feeding.

[0012] Optionally, the outer wall of the hopper body is provided with two support parts, the support parts are provided with positioning holes, the mounting frame is provided with a support frame at one end near the metering hopper, the support frame is provided with a positioning pin that matches the positioning hole, and the positioning pin passes through the positioning hole on the support part.

[0013] By adopting the above technical solution, the mounting frame is equipped with two positioning pins on the support frame and two support parts on the outer wall of the hopper body. The support parts are equipped with positioning holes, and the two positioning pins pass through the two positioning holes. Under the premise of ensuring the reliability of the connection between the mounting frame and the hopper body, it helps to improve the convenience of installation and disassembly of the hopper body and the mounting frame.

[0014] Optionally, the hopper gate includes a gate body and a rotating part. The rotating part is disposed at one end of the gate body, and a rotating shaft is provided at the end of the rotating part away from the gate body. The rotating shaft is rotatably mounted on the mounting frame.

[0015] By adopting the above technical solution, the hopper gate has a rotating part on the gate body, and a rotating shaft on the rotating part. The rotating shaft is rotatably connected to the mounting frame, which helps the drive assembly to drive the rotating shaft to rotate, thereby opening or closing the hopper gate.

[0016] Optionally, the drive assembly includes a cylinder and a push rod, one end of the push rod being fixedly connected to the end of the rotating shaft away from the rotating part, and the other end being hinged to the piston rod of the cylinder, and the cylinder body being hinged to the mounting bracket.

[0017] By adopting the above technical solution, when the piston rod of the cylinder extends, the push rod pushes the rotating shaft to rotate, causing the hopper gate to disengage from the discharge port of the hopper body, and the rice raw materials for zongzi in the hopper body are fed from the discharge port. When the piston rod of the cylinder retracts, the hopper gate closes the discharge port of the hopper body, and the weighing sensor weighs and measures the rice raw materials entering the hopper body, thereby improving the efficiency of metering and feeding.

[0018] Optionally, it also includes a buffer hopper, which is fixedly installed on the outer wall of the machine body, and the discharge end of the buffer hopper passes through the inlet of the metering hopper.

[0019] By adopting the above technical solution, the buffer hopper is installed on the outer wall of the machine body, and the discharge end of the buffer hopper passes through the inlet of the metering hopper. In this way, the rice raw material to be measured is first buffered by the buffer hopper and then falls into the metering hopper for measurement. This helps to reduce the impact of the rice raw material to be measured on the metering hopper and improve the accuracy of the metering hopper in measuring the rice raw material.

[0020] Optionally, it also includes a feeding hopper, which is fixedly installed on the outer wall of the machine body, and the feeding port of the feeding hopper is located directly below the discharge port of the metering hopper, and the cross-sectional area of ​​the feeding port of the feeding hopper is smaller than the cross-sectional area of ​​the discharge port of the metering hopper.

[0021] By adopting the above technical solution, the metering hopper puts the metered rice raw material into the feeding hopper. Under the restriction of the feeding port of the feeding hopper, the rice raw material is fed into the zongzi mold cavity from the feeding port with a smaller cross-sectional area, which helps to improve the accuracy of feeding into the zongzi mold cavity.

[0022] Optionally, a sealing assembly is provided between the mounting bracket and the mounting hole. The sealing assembly includes a flexible seal and a compression flange. The flexible seal is installed on the inner wall of the body through the compression flange. The flexible seal has a sealing port. The mounting bracket passes through the sealing port and is sealed to the flexible seal.

[0023] By adopting the above technical solution, a sealing component is set between the mounting bracket and the mounting hole. The sealing component presses the flexible seal onto the inner wall of the machine body through the clamping flange, which facilitates quick disassembly of the flexible seal and convenient replacement and maintenance of the flexible seal. The flexible seal has a sealing port, and the mounting bracket passes through the sealing port and is flexibly connected to the flexible seal, which helps to prevent external moisture and waste from entering the machine body, improves the protection effect of the components installed inside the machine body, and extends the service life of the components. At the same time, the flexibility of the flexible seal allows for a flexible connection between the flexible seal and the mounting bracket, which can ensure the accuracy of the weighing sensor in measuring the rice raw material in the metering hopper.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The metering hopper is fitted with the mounting holes on the side wall of the machine body through a mounting bracket, so that it can be stably set outside the machine body, which facilitates feeding and material supply operations. At the same time, the weighing sensor is fixedly installed on the fixed bracket located inside the machine body, which effectively avoids the influence of the external environment, improves the weighing accuracy and stability, and thus improves the feeding efficiency and reliability of the entire feeding device.

[0026] 2. The mounting bracket is limited by the limiting groove and limiting part in the limiting component, which helps to limit the displacement of the mounting bracket during weighing, thereby reducing the risk of damage to the weighing sensor due to exceeding the measurement range, and further improving the measurement accuracy and system safety.

[0027] 3. The drive assembly drives the hopper gate to open and close via cylinders and push rods, enabling rapid feeding and accurate metering, thus improving the efficiency of metering and feeding. At the same time, the closed state of the hopper gate helps to weigh the rice raw material entering the hopper, ensuring the accuracy of metering. Attached Figure Description

The metering mechanism passes through the mounting frame 3 through the mounting hole 11 on the side wall of the body and fits with the mounting hole 11 with a clearance, so that the metering hopper 2 is stably set outside the body 1, which facilitates feeding and material supply operations. The weighing sensor 5 is fixedly installed on the fixing frame 4 located inside the body 1, so that the weighing sensor 5 is not affected by the external environment, improving the weighing accuracy and stability, thereby improving the feeding efficiency and reliability of the entire feeding device.

[0038] Reference Figure 2The measuring mechanism also includes a limiting component 6 for limiting the mounting frame 3. The limiting component 6 includes a limiting member 61, which is fixedly installed on the inner wall of the machine body 1. The limiting member 61 is provided with a limiting groove 611, and the mounting frame 3 is provided with a limiting part 31. By providing a limiting groove 611 on the limiting member 61 and a limiting part 31 on the mounting frame 3, and by providing a gap between the two ends of the limiting part 31 and the inner walls on both sides of the limiting groove 611, the displacement of the mounting frame 3 during weighing is limited, thereby reducing the load cell 5. Damage caused by exceeding the measurement range; In this embodiment, the limiting part 31 is a bolt that is threadedly fixed to the mounting bracket 3. The two ends of the bolt are located in the limiting groove 611 and are separated from the inner walls on both sides of the limiting groove 611.

In other embodiments of this application, the limiting part 31 can also be a limiting rod that is fixedly installed on the mounting bracket 3. The two ends of the limiting rod are located in the limiting groove 611 and are separated from the inner walls on both sides of the limiting groove 611.

[0039] Reference Figure 1 and Figure 2 The metering hopper 2 includes a hopper body 21, a hopper door 22 rotatably disposed at the discharge port of the hopper body 21, and a drive assembly 23 mounted on the mounting frame 3 to drive the hopper door 22 to open or close. The hopper door 22 can close the discharge port of the hopper body 21, which facilitates the weighing and metering of the rice glutinous rice raw material entering the hopper body 21. When feeding is required, the drive assembly 23 drives the hopper door 22 to open, so that the metered rice glutinous rice raw material in the hopper body 21 can be quickly discharged from the discharge port, thereby improving the efficiency of metering and feeding.

[0040] Reference Figure 4 and Figure 5 The outer wall of the hopper body 21 is provided with two support parts 211, and the two support parts 211 are respectively provided with positioning holes 2111. The mounting frame 3 is provided with a support frame 32 at one end near the metering hopper 2. The support frame 32 can be fixed to the mounting frame 3 by screw fastening or welding. The support frame 32 is provided with two positioning pins 321 that are adapted to the two positioning holes 2111. The two positioning pins 321 pass through the two positioning holes 2111. By providing two positioning pins 321 on the support frame 32 and two support parts 211 on the outer wall of the hopper body 21, and providing positioning holes 2111 on the support parts 211, and having two positioning pins 321 pass through the two positioning holes 2111, the mounting frame 3 helps to improve the convenience of installation and disassembly of the hopper body 21 and the mounting frame 3, while ensuring the reliability of the connection between the mounting frame 3 and the hopper body 21.

[0041] Reference Figure 1 and Figure 2The hopper gate 22 includes a gate body 221 and a rotating part 222. The rotating part 222 is located at one end of the gate body 221, and a rotating shaft 223 is provided at the end of the rotating part 222 away from the gate body 221. The rotating shaft 223 is rotatably mounted on the mounting frame 3 through a bearing. By setting the rotating part 222 on the gate body 221 and the rotating shaft 223 on the rotating part 222, and the rotating shaft 223 is rotatably connected to the mounting frame 3, the hopper gate 22 can be quickly opened or closed by the drive assembly 23 driving the rotating shaft 223 to rotate, thereby improving the working efficiency of the metering hopper 2 in metering or feeding conversion.

[0042] Reference Figure 1 and Figure 2 The drive assembly 23 includes a cylinder 231 and a push rod 232. One end of the push rod 232 is fixedly connected to the end of the rotating shaft 223 away from the rotating part 222, and the other end is hinged to the piston rod of the cylinder 231. The cylinder body of the cylinder 231 is hinged to the mounting bracket 3. When the piston rod of the cylinder 231 extends, the push rod 232 pushes the rotating shaft 223 to rotate, causing the hopper gate 22 to disengage from the discharge port of the hopper body 21, and the rice raw material of the zongzi in the hopper body 21 is fed from the discharge port. When the piston rod of the cylinder 231 retracts, the hopper gate 22 closes the discharge port of the hopper body 21. The weighing sensor 5 weighs and measures the rice raw material entering the hopper body 21, thereby improving the efficiency of measurement and feeding.

[0043] Reference Figure 1 It also includes a buffer hopper 7, which is fixedly installed on the outer wall of the machine body 1, and the discharge end of the buffer hopper 7 passes through the inlet of the metering hopper 2. With the buffer hopper 7 installed on the outer wall of the machine body 1 and the discharge end of the buffer hopper 7 passing through the inlet of the metering hopper 2, the rice raw material to be measured first passes through the buffer hopper 7 for buffering, and then falls into the metering hopper 2 for metering. This helps to reduce the impact of the rice raw material to be measured on the metering hopper 2 and improve the accuracy of the metering hopper 2 in measuring the rice raw material.

[0044] Reference Figure 1 It also includes a feeding hopper 8, which is fixedly installed on the outer wall of the machine body 1. The inlet of the feeding hopper 8 is located directly below the outlet of the metering hopper 2. The cross-sectional area of ​​the feeding inlet of the feeding hopper 8 is smaller than the cross-sectional area of ​​the outlet of the metering hopper 2. The metering hopper 2 feeds the metered rice raw material into the feeding hopper 8. Under the restriction of the feeding inlet of the feeding hopper 8, the rice raw material is fed into the zongzi mold cavity from the feeding inlet with a smaller cross-sectional area, which helps to guide the rice raw material smoothly into the zongzi mold cavity and improves the accuracy of feeding into the zongzi mold cavity.

[0045] Reference Figure 2A sealing assembly 9 is provided between the mounting bracket 3 and the mounting hole 11. The sealing assembly 9 includes a flexible seal 91 and a clamping flange 92. The flexible seal 91 is installed on the inner wall of the machine body through the clamping flange 92. The flexible seal 91 has a sealing port 911. The mounting bracket 3 passes through the sealing port 911 and is sealed to the flexible seal 91. The flexible seal 91 is made of silicone material, which has good flexibility and sealing performance. The thickness of the flexible seal 91 is 2mm, ensuring its effectiveness under sealing conditions. The sealing assembly 9 is provided between the mounting bracket 3 and the mounting hole 11. The sealing assembly 9 is connected to the machine body through the clamping flange 92. The flexible seal 91 is pressed and installed on the inner wall of the machine body, which facilitates quick disassembly of the flexible seal 91 and makes it convenient to replace and maintain the flexible seal 91. The flexible seal 91 has a sealing port 911, and the mounting bracket 3 passes through the sealing port 911 and is flexibly connected to the flexible seal 91. This helps to prevent external moisture and waste from entering the machine body, improves the protection effect of the components installed inside the machine body, and extends the service life of the components. At the same time, the flexibility of the flexible seal 91 allows for a flexible connection between the flexible seal 91 and the mounting bracket 3, which can ensure the accuracy of the weighing sensor 5 in measuring the rice raw material in the metering hopper 2.

[0046] The implementation principle of a rice raw material metering mechanism for zongzi (sticky rice dumplings) is as follows: By installing the metering hopper 2 outside the machine body 1, and with the mounting frame 3 and mounting hole 11 in clearance fit, the metering hopper 2 is stably positioned outside the machine body 1, facilitating feeding and material supply operations. The weighing sensor 5 is fixedly installed on the fixed frame 4 located inside the machine body 1, avoiding the influence of the external environment and improving weighing accuracy and stability. Simultaneously, by setting the limiting component 6, driving component 23, support part 211, positioning pin 321, sealing component 9, buffer hopper 7, and feeding hopper 8, the reliability and working efficiency of the metering mechanism are further improved, solving problems existing in related technologies and significantly enhancing the accuracy and efficiency of metering and feeding.
