Technical Field

[0001] This utility model relates to the field of hand-rolled rice ball technology, and in particular to an automatic double-row transfer and discharge device for hand-rolled rice balls. Background Technology

[0002] Hand-rolled rice balls are a convenient, delicious, and versatile food suitable for breakfast, bento boxes, or snacks. They combine ingredients such as rice, vegetables, and meat, wrapped in seaweed or plastic wrap into a roll shape, making them easy to carry and eat.

[0003] Hand-rolled rice balls are made by steaming rice in a rice cooker with water according to the specified ratio, ensuring the rice is cooked to the right consistency. Meat is added after being marinated, grilled, or pan-fried and then cut into pieces. Vegetables are washed, shredded, or diced. Other ingredients are prepared as needed. Then, a rice ball machine or a custom mold is used to press the rice into a cylindrical or triangular basic shape.

[0004] The existing rice balls, after being shaped, cannot be automatically placed into packaging boxes. Operators need to manually put them into the packaging boxes and send them to the packaging machine for packaging, resulting in low packaging efficiency and thus affecting production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, rice balls cannot be automatically put into the packaging box after being formed. Operators need to manually put them into the packaging box and send them to the packaging machine for packaging, which results in low packaging efficiency and thus affects production efficiency.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 4 As shown, this utility model provides an automatic double-row transfer and discharge device for hand-rolled rice balls, including a double-row transfer conveyor belt 1. A movable discharge assembly 2 is connected to one side of the double-row transfer conveyor belt 1. The movable discharge assembly 2 includes a discharge plate 201, with symmetrically arranged discharge grooves 202 on the surface of the discharge plate 201. A movable platform 203 is connected to the lower end of the discharge plate 201. A one-way screw 204 is inserted inside the movable platform 203. One end of the one-way screw 204 is connected to a bearing 205, and the other end is connected to the output end of a motor 206. A movable frame 207 is provided on the surface of the one-way screw 204. A threaded hole 208 is provided through the interior of the 7. A placement rack 209 is provided directly above the moving frame 207. Two sets of packaging boxes 210 are placed on the surface of the placement rack 209. A PLC controller 211 is connected to the front end of one side of the double-row transfer conveyor belt 1. A packaging machine 3 is connected to the upper end of one side of the moving table 203. The PLC controller 211 is electrically connected to an external power supply through a control switch. The PLC controller 211 is electrically connected to the double-row transfer conveyor belt 1, the motor 206, and the packaging machine 3. Two sets of pressure sensors are also provided on the top of the placement rack 209. The one-way screw 204 and the bearing 205 form a rotatable connection.

[0024] The overall effect of Embodiment 1 is as follows: After the rice balls are produced, they can be placed on the double-row transfer conveyor belt 1. Then, the PLC controller 211 is turned on, enabling the PLC controller 211 to start the double-row transfer conveyor belt 1, causing the rice balls to move to the lower plate 201, slide down through the feeding chute 202, and fall into the two sets of packaging boxes 210 in the placement rack 209. After being detected, the two sets of gravity sensors in the placement rack 209 send an electrical signal to the PLC controller 211, causing the PLC controller 211 to activate the forward rotation function of the motor 206, so that the motor 206 can drive the unidirectional screw through the output end. 204 rotates forward, allowing the one-way screw 204 to send forward screw rotation through the threaded hole 208 and the moving frame 207. This movement of the moving frame 207 drives the placement rack 209 and the packaging box 210 into the packaging machine 3. After being packaged by the packaging machine 3, the packaging continues to move forward. After the packaging personnel remove the packaged box 210, the motor 206 automatically activates the reverse function, allowing the moving frame 207 to move the placement rack 209 to the bottom position of the feeding plate 201. Then, the new packaging box 210 is placed on the surface of the placement rack 209, ready for the next packaging, thus improving the production efficiency of rice balls.

[0025] Example 2, as Figure 1 and Figure 5 As shown, shock-absorbing and protective components 4 are provided at the four corners of the interior of the movable frame 207. Each shock-absorbing and protective component 4 includes a slot 401. A spring 402 is provided inside each slot 401. A top block 403 is connected to the top of the spring 402. A top rod 404 is connected to the top of the top block 403. A rubber pad 405 is provided on the upper surface of the movable frame 207. The outer surface of the top block 403 is in contact with the inner wall of the slot 401. An elastic structure is formed between the top block 403 and the spring 402.

[0026] The effect achieved by the entire embodiment 2 is that when the rice ball falls into the packaging box 210, the placement rack 209 will be impacted, which will cause the placement rack 209 to push the top rod 404 to drive the top block 403 to squeeze the spring 402, thus playing a shock absorption role. When the bottom of the placement rack 209 contacts the rubber pad 405, it can play a secondary shock absorption role, thus protecting the rice ball and avoiding the problem of the rice ball breaking due to large impact force.

[0027] Working principle: Through the double-row conveyor belt 1 and the feeding plate 201, the rice balls can automatically fall into the packaging box 210. Then, under the action of the motor 206, they are transported to the packaging machine 3 for automatic packaging. No manual operation is required, which improves the production efficiency of rice balls. When the rice balls fall into the packaging box 210, the springs 402 between the placement frame 209 and the moving frame 207 can reduce the impact force when the rice balls fall into the packaging box 210, thus protecting the rice balls and avoiding the problem of rice balls breaking due to large impact force.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
