Description

Technical Field

[0001] This application relates to the field of zongzi production equipment technology, and in particular to a zongzi rice raw material feeding mechanism. Background Technology

[0002] The rice feeding mechanism for zongzi (sticky rice dumplings) is a crucial component of food processing equipment, primarily used to evenly deliver the rice raw materials into subsequent processes. With the development of the food industry and the increasing level of automation, the requirements for production equipment are also rising. An efficient material conveying system not only improves production efficiency but also ensures the consistency and stability of product quality. Therefore, developing an efficient and reliable rice feeding mechanism for zongzi is of significant practical importance.

[0003] Currently, the common methods for feeding rice for zongzi (sticky rice dumplings) on the market mainly include screw conveyors, belt conveyors, and vibrating feeders. Among them, screw conveyors are suitable for short-distance, low-speed conveying, but they are prone to clogging and difficult to clean; belt conveyors are suitable for long-distance, high-speed conveying, but they are prone to generating dust when conveying powdery materials and have certain limitations on the moisture content of the materials; vibrating feeders are a more ideal conveying method, which uses a vibrating device to make the material jump forward on the feeding plate. They have the characteristics of simple structure, low energy consumption, and strong adaptability, and are widely used in conveying various powdery and granular materials.

[0004] However, the related vibratory feeding mechanisms generally have some shortcomings. The vibrators are easily contaminated by moisture and waste materials, which leads to a shortened lifespan of the vibrators and requires frequent maintenance, thus limiting the promotion and development of vibratory feeding mechanisms in practical applications. Utility Model Content

[0005] To address the technical issue of improving the service life of vibrators, this application provides a rice feeding mechanism for zongzi (sticky rice dumplings), employing the following technical solution:

[0006] A feeding mechanism for rice for zongzi (sticky rice dumplings) includes a machine body, a feeding tray spaced apart from the table surface of the machine body, a vibrator installed in the machine body, a vibrating part on the top of the vibrator, a vibrating hole on the table surface of the machine body, the vibrating part passing through the vibrating hole and being in clearance fit with the vibrating hole, and the vibrating part being connected to the bottom of the feeding tray through a connecting component.

[0007] By adopting the above technical solution, the feeding tray is placed outside the machine body, and the vibrator is installed inside the machine body. The vibrating part of the vibrator passes through the vibration hole on the machine body table and is connected to the feeding tray through the connecting assembly. Placing the feeding tray outside the machine body facilitates the feeding and unloading of rice raw materials. The connection with the vibrating part through the connecting assembly allows the feeding tray to be disassembled for easy maintenance. Placing the vibrator inside the machine body helps prevent moisture and waste from contaminating the vibrator, improving the vibrator's protective effect and helping to extend its service life.

[0008] Optionally, the connecting assembly includes a ring seat installed on the vibrating part and a plug-in component slidably installed on the bottom of the feeding tray. The ring seat is provided with a plug-in hole that matches the plug-in portion of the plug-in component.

[0009] By adopting the above technical solution, the ring seat is installed on the vibrating part, and the plug-in is slidably installed on the bottom of the feeding tray. The ring seat is provided with a plug-in hole that matches the plug-in part of the plug-in. In this way, by pushing the plug-in to insert the plug-in part into the plug-in hole, the feeding tray and the vibrating part are fixedly connected, which helps the feeding tray receive the vibration force transmitted by the vibrating part and improves the feeding efficiency of the feeding tray. Pushing the plug-in to disengage the plug-in part from the plug-in hole helps the feeding tray to be quickly disassembled from the vibrating part, which facilitates the maintenance of the feeding tray and the vibrator.

[0010] Optionally, a push rod is hinged to one end of the connector away from the connector portion, and a lever is installed at the bottom of the feeding tray. One end of the lever is hinged to the bottom of the feeding tray, and the middle part of the lever is hinged to the end of the push rod away from the connector.

[0011] By adopting the above technical solution, the push rod is pushed by rotating the lever to move relative to the feeding plate, thereby allowing the insertion part of the connector to quickly insert into or detach from the insertion hole. This enables the connector to quickly detach from or lock with the ring seat, improving the operability of installing or disassembling the feeding plate and the vibrating part.

[0012] Optionally, the connecting assembly further includes an elastic sleeve, and the vibration hole is provided with a protective ring protruding from the machine body platform along the circumference. The elastic sleeve is fitted into the ring seat, and one end of the elastic sleeve is sealed to the protective ring, and the other end is sealed to the end of the ring seat away from the insertion hole.

[0013] By adopting the above technical solution, one end of the elastic sleeve is sealed to the end of the ring seat away from the insertion hole, and the other end is sealed to the protective ring. Without affecting the vibration of the vibrating part and ensuring uniform feeding of the feeding disc, it can also prevent moisture or waste from entering the machine body from the vibration hole, which helps to improve the protection effect on the vibrator or other components, thereby increasing the service life of the vibrator and other internal components of the machine body.

[0014] Optionally, the feeding tray includes a tray body, with a discharge port at one bottom and a slope at the other bottom to prevent material from accumulating. The width of the tray body gradually decreases from the slope end to the discharge port end.

[0015] By adopting the above technical solution, a slope is set at the bottom of one end of the feeding tray, which helps to prevent material from being stored after the feeding tray receives the material. The width of the tray gradually decreases from one end of the slope to one end of the discharge port, which helps to make the rice material gather at the discharge port during the conveying process, improves the discharge efficiency, and facilitates the rice material to enter the discharge hopper.

[0016] Optionally, the feeding tray further includes a first liner plate installed on the slope and a second liner plate installed on the bottom surface inside the feeding tray, wherein the side of the first liner plate near the second liner plate is abutted against the side of the second liner plate near the first liner plate.

[0017] By adopting the above technical solution, the feeding tray, by installing a first liner on the slope and a second liner on the inner bottom, helps to prevent rice raw materials from sticking to the slope or inner bottom during the conveying process, thereby improving conveying efficiency. The first liner and the second liner are installed close together, which helps to prevent gaps from forming at the connection between the two, thus preventing rice raw materials from being retained.

[0018] Optionally, the feeding tray may further include a plurality of material leveling components, which are spaced apart and installed on the inner sidewall of the feeding tray.

[0019] By adopting the above technical solution, the feeding tray has several material leveling components installed on its inner wall. When the feeding tray is conveying rice raw materials, the material leveling components scrape the accumulated rice raw materials, which helps to improve the consistency of the rice raw material conveying flow, prevent the rice raw materials from being blocked at the discharge port, and improve the reliability of the operation.

[0020] Optionally, the material equalizer has mounting plates at both ends, and the mounting plates have elongated holes along the width direction of the material equalizer. The side wall of the feeding tray has mounting holes that are adapted to the width of the elongated holes. The elongated holes are threadedly connected to the mounting holes by through screws. Tightening the screws causes the mounting plates to be pressed and fixed on the inner side wall of the feeding tray.

[0021] By adopting the above technical solution, and by setting elongated holes on the mounting plates at both ends of the material equalizer, it is convenient to adjust the height of the scraping side of the material equalizer relative to the bottom surface of the feeding tray, thereby enabling rapid adjustment of the flow rate of rice raw materials conveyed by the feeding tray.

[0022] Optionally, the material equalizer has several serrations on one side near the bottom of the feeding tray.

[0023] By adopting the above technical solution, by setting several serrations on one side of the material leveling component near the bottom of the feeding disc, the resistance generated by the feeding disc during feeding can be reduced. At the same time, it also helps to reduce the blockage of raw materials on one side of the material leveling component during material leveling.

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

[0025] 1. By placing the feeding tray outside the machine body and installing the vibrator inside the machine body, the vibrating part passes through the vibration hole and is connected to the feeding tray through the connecting assembly, making it easy to load and unload materials onto the feeding tray. At the same time, the vibrator is well protected, avoiding contamination by moisture and waste materials, and extending the service life of the vibrator.

[0026] 2. The design of the connecting components, especially the fit between the ring seat and the plug, enables the feeding tray to be quickly disassembled and installed, improving the convenience of maintenance and work efficiency;

[0027] 3. The use of elastic sleeves ensures the sealing of the vibration holes, further enhances the protection of the vibrator and other components, and improves the reliability and service life of the entire system. Attached Figure Description

Detailed Implementation

[0034] The following combination Figures 1 to 4 This application will be described in further detail.

[0035] This application discloses a feeding mechanism for rice ingredients used in making zongzi (sticky rice dumplings).

[0036] A feeding mechanism for rice ingredients for zongzi (sticky rice dumplings), referring to Figure 1 and Figure 2 The system includes a body 1, a feeding tray 2, and a vibrator 3. The feeding tray 2 is spaced apart from the table surface of the body 1. The vibrator 3 is installed inside the body 1, and a vibrating part 31 is provided on the top of the vibrator 3. Vibration holes 11 are provided on the table surface of the body 1. The vibrating part 31 passes through the vibration holes 11 and is clearance-fitted with the vibration holes 11. The vibrating part 31 is connected to the bottom of the feeding tray 2 through a connecting assembly 4. By placing the feeding tray 2 outside the body 1 and installing the vibrator 3 inside the body 1, with the vibrating part 31 of the vibrator 3 passing through the vibration holes 11 on the table surface of the body 1 and connected to the feeding tray 2 through the connecting assembly 4, the feeding tray 2 being placed outside the body 1 facilitates the feeding of rice raw materials. The feeding tray 2 can be disassembled and maintained by connecting the connecting component 4 to the vibrating part 31. The vibrator 3 is located inside the machine body 1, which helps to prevent moisture and waste from contaminating the vibrator 3, improves the protective effect of the vibrator 3, and helps to extend the service life of the vibrator 3. It should be noted that the vibrator 3 in this embodiment is an electromagnetic vibrator 3, while other embodiments of this application are motor-driven eccentric wheel vibrators 3. A fixing plate 13 is provided on the inner wall of the machine body 1, and the vibrator 3 is fixedly installed on the fixing plate 13 by a buffer pad 5, which helps to reduce the vibration of the vibrator 3 transmitted to the machine body 1 and affect the normal operation of other components.

[0037] Reference Figure 2 and Figure 3 The connecting component 4 includes a ring seat 41 and a connector 42. The ring seat 41 is fixedly mounted on the vibrating part 31. A blind hole is provided at one end of the ring seat 41 near the vibrating part 31, and a through hole is provided at the bottom of the blind hole. A screw passes through the through hole and fixes the ring seat 41 to the end face of the vibrating part 31. A connector hole 411 is provided on the ring wall of the ring seat 41, and the connector 42's connector portion 421 is adapted to the connector hole 411. A notch for accommodating the connector 42 is provided at the end of the ring seat 41 away from the vibrating part 31. 2 can be installed at the bottom of the feeding tray 2 by means of a chute or slide rail. In this way, by pushing the plug 42 to insert the plug part 421 into the plug hole 411, the feeding tray 2 is fixedly connected to the vibrating part 31, which helps the feeding tray 2 to receive the vibration force transmitted by the vibrating part 31 and improve the feeding efficiency of the feeding tray 2. Alternatively, by pushing the plug 42 to disengage the plug part 421 from the plug hole 411, the feeding tray 2 can be quickly disassembled from the vibrating part 31, which facilitates the maintenance of the feeding tray 2 and the vibrator 3.

[0038] Reference Figure 3The end of the connector 42 away from the connector portion 421 is hinged to the push rod 43. The bottom of the feeding tray 2 is equipped with a lever 44. One end of the lever 44 is hinged to the bottom of the feeding tray 2, and the middle part of the lever 44 is hinged to the end of the push rod 43 away from the connector 42. By rotating the lever 44, the push rod 43 is pushed to move relative to the feeding tray 2, thereby allowing the connector portion 421 of the connector 42 to quickly insert into or disengage from the connector hole 411. This enables the connector 42 to quickly disengage from or lock with the ring seat 41, improving the operability of installing or disassembling the feeding tray 2 and the vibrating part 31.

[0039] Reference Figure 3 The connecting assembly 4 also includes an elastic sleeve 45. The vibration hole 11 has a protective ring 12 protruding from the machine body platform along its circumference. The elastic sleeve 45 is fitted into the ring seat 41, with one end of the elastic sleeve 45 sealed to the protective ring 12 and the other end sealed to the end of the ring seat 41 away from the insertion hole. The elastic sleeve 45 is made of elastic rubber, and its shape can be corrugated or spherical. The end of the elastic sleeve 45 near the ring seat 41 can be fixedly connected to the ring seat 41 by means of a pipe clamp, or by pressing the wall of the elastic sleeve 45 tightly against the ring seat 41. The ring seat 41 is fixed to the joint end face of the vibrating part 31 in any way that can achieve a firm and sealed connection to one end of the elastic sleeve 45. The end of the elastic sleeve 45 near the protective ring 12 is connected by a pipe clamp. In this way, without affecting the vibration of the vibrating part 31 to make the feeding plate 2 feed evenly, it can prevent moisture or waste from entering the machine body from the vibration hole 11. This helps to improve the protection effect of the vibrator 3 or other internal components of the machine body 1, thereby improving the service life of the vibrator 3 and other internal components of the machine body 1.

[0040] Reference Figure 1 and Figure 2 The feeding tray 2 includes a tray body 21. One end of the tray body 21 has a discharge port 211 at its bottom, and the other end has a slope 212 at its bottom to prevent material accumulation. The width of the tray body 21 gradually decreases from one end of the slope 212 to one end of the discharge port 211. The slope 212 at one end of the feeding tray 2 helps to prevent material accumulation after the feeding tray 2 receives material. The gradual decrease in width of the tray body 21 from one end of the slope 212 to one end of the discharge port 211 helps to concentrate the rice raw material at the discharge port 211 during the conveying process, improving the feeding efficiency and facilitating the entry of the rice raw material into the discharge hopper. It should be noted that the tray body 21 can be installed at a slight tilt, so that the inner bottom surface of the tray body 21 near the discharge port 211 is lower than the inner bottom surface of the side near the slope 212. In this way, during the feeding process, the vibration of the vibrating part 31 of the vibrator 3 and the gravity of the rice raw material improve the feeding efficiency of the rice raw material.

[0041] Reference Figure 2 and Figure 4 The feeding tray 2 also includes a first liner 22 installed on the slope 212 and a second liner 23 installed on the inner bottom surface of the feeding tray 2. The side of the first liner 22 near the second liner 23 is tightly fitted against the side of the second liner 23 near the first liner 22. The feeding tray 2 is constructed by installing the first liner 22 on the slope 212 and the second liner 23 on the inner bottom surface. Both the first liner 22 and the second liner 23 can be made of food-grade nylon or plastic. The contact surface of the second liner 23 with the rice raw material is along the raw material... The conveying direction is provided with toothed corrugations 231. Similarly, the first liner 22 is also provided with similar toothed corrugations. It is fixed to the inner bottom surface of the slope 212 and the feeding tray 2 by screw fastening, which can reduce the weight of the equipment and facilitate replacement and maintenance. The toothed corrugations 231 help reduce the adhesion of rice raw materials to the first liner 22 and the second liner 23 during the conveying process, thereby improving the conveying efficiency. The first liner 22 and the second liner 23 are installed in close contact, which helps to prevent gaps from forming at the connection between the two, causing rice raw materials to remain.

[0042] Reference Figure 1 and Figure 2 The feeding tray 2 also includes several equalizing components 24, which are installed at intervals on the inner wall of the feeding tray 2. By installing several equalizing components 24 on the inner wall of the feeding tray 2, the number of equalizing components 24 in this embodiment is 2 or 3, depending on the length of the feeding tray 2. When the feeding tray 2 is conveying rice raw materials, the several equalizing components 24 scrape the accumulated rice raw materials, which helps to improve the consistency of the rice raw material conveying flow, prevent the rice raw materials from being blocked at the discharge port 211, and improve the reliability of the operation.

[0043] Reference Figure 1 and Figure 2 The material equalizer 24 has mounting plates 241 at both ends. The mounting plates 241 have elongated holes 2411 along the width of the material equalizer 24. The side wall of the feeding tray 2 has mounting holes 213 that are adapted to the size of the elongated holes 2411. Screws 25 pass through the elongated holes 2411 and are threaded into the mounting holes 213. Tightening the screws 25 makes the mounting plates 241 press and fix them on the inner side wall of the feeding tray 2. By setting elongated holes 2411 on the mounting plates 241 at both ends of the material equalizer 24, it is convenient to adjust the height of the scraping side of the material equalizer 24 relative to the inner bottom surface of the feeding tray 2, thereby enabling quick adjustment of the flow rate of raw materials conveyed by the feeding tray 2.

[0044] Reference Figure 1The material leveling component 24 has several serrations 242 on one side near the bottom of the feeding disc 2. By setting several serrations 242 on one side of the material leveling component 24 near the bottom of the feeding disc 2, the resistance generated by the feeding disc 2 during feeding can be reduced. At the same time, it also helps to reduce the problem of raw material blockage on one side of the material leveling component 24 during material leveling.

[0045] The implementation principle of a rice feeding mechanism for zongzi (sticky rice dumplings) is as follows: A vibrator 3 is installed inside the machine body 1, and a feeding tray 2 is located outside the machine body 1. The vibrating part 31 of the vibrator 3 is connected to the feeding tray 2 via a connecting assembly 4, achieving efficient vibration feeding from the feeding tray 2. The connecting assembly 4 adopts a combination design of a ring seat 41, a plug-in part 42, a push rod 43, and a lever part 44, ensuring a reliable connection between the feeding tray 2 and the vibrating part 31 while facilitating the disassembly and maintenance of the feeding tray 2. The design of the elastic sleeve 45 effectively prevents moisture and waste from entering the machine body 1, improving the protective effect of the vibrator 3. The slope 212 design of the feeding tray 2 and the setting of the material equalization part 24 ensure the uniform distribution of rice raw materials on the feeding tray 2, improving feeding efficiency and reliability. The overall design not only solves the problems existing in related technologies but also improves the performance and service life of the vibration feeding mechanism.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
