Description

Technical Field

[0001] This utility model relates to a food production equipment, and more particularly to an automatic filling device for an egg dumpling forming machine. Background Technology

[0002] Egg dumplings are a type of hot pot ingredient, made with fillings of fresh shrimp, pork, or chicken, wrapped in an egg skin. Because eggs are rich in protein, fat, vitamins, and minerals such as iron, calcium, and potassium, they are widely popular among consumers.

[0003] Currently, the filling mechanism of most dumpling machines on the market generally uses a cylinder combined with a filling nozzle and other components to form an air blowing device. This device has two through-holes on either side of the filling nozzle; the larger one is for filling, and the smaller one is for air blowing. During operation, the cylinder compresses gas to push the filling through the filling tube to the filling nozzle. Simultaneously, a solenoid valve controls the air blowing tube to compress air, which is then delivered through the air blowing tube to the air blowing hole. The air is further compressed and ejected, causing the filling to land on the dumpling skin, completing the filling process. While this filling method allows for automated production, the shape of the sprayed filling is irregular, and precise metering is impossible, leading to quantity deviations. Additionally, some filling can stick to the outlet, easily breeding bacteria and causing contamination, affecting the quality of the dumpling product. Furthermore, during the filling process, operators need to clean the filling nozzle and dumpling mold of loose filling periodically, increasing downtime for maintenance and impacting production efficiency and output, thus hindering the orderly operation of daily dumpling production.

[0004] To address the aforementioned issues, this application presents an automatic filling device for an egg dumpling forming machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic filling device for an egg dumpling forming machine, including: a filling feeding mechanism, a filling filling mechanism, and a filling pushing mechanism.

[0006] The filling feeding mechanism includes: a hopper, a lever base, a rotating shaft, and a rotating drive device. A filling box is provided below the hopper, and the bottom of the filling box is provided with several filling feeding slots. The lever base is connected to the bottom of the filling box. The lever base is provided with a filling inlet pipe, a filling injection pipe, and a filling push pipe inside. The filling inlet pipe is connected to the filling feeding slots. The rotating shaft is rotatably disposed inside the lever base. A connecting pipe is provided inside the rotating shaft. The rotating drive device can drive the rotating shaft to rotate inside the lever base, thereby connecting the connecting pipe to the filling inlet pipe and the filling injection pipe, or connecting the filling injection pipe and the filling push pipe.

[0007] The filling mechanism is connected to the filling pipe and can provide positive and negative pressure to the connecting pipe through the filling pipe, thereby drawing the filling from the filling pipe into the filling pipe, and then squeezing it from the filling pipe into the pushing pipe and entering the pushing mechanism through the filling guide pipe provided at the bottom of the pushing pipe.

[0008] The filling pushing mechanism is connected to the lever base and includes: a filling pushing cylinder, a filling pushing cavity component, a filling pushing slider, and a pneumatic component. The filling pushing cavity component is connected to the filling pushing pipe. The filling pushing cylinder is driven by the filling pushing slider, causing the filling pushing slider to move up and down within the filling pushing cavity component. The pneumatic component is slidably disposed within the filling pushing slider. The filling pushing slider is connected to a compressed air valve for pushing the pneumatic component. The compressed air valve pumps in compressed air to push the pneumatic component to move inside the filling pushing slider, and causes the compressed air to be released downward along the air guide gap of the filling pushing slider, spraying the filling downward.

[0009] The filling mechanism includes a filling cylinder, a fixed plate, and an adjusting screw. The fixed plate is connected to the lever seat through the adjusting screw. The fixed plate is provided with a piston through hole. The piston rod of the filling cylinder passes through the piston through hole and extends into the filling pipe, thereby creating positive and negative air pressure inside the filling pipe when the piston rod performs telescopic movement.

[0010] The hopper is equipped with a stirring device above it via a support frame. The stirring device includes a stirring motor, a stirring shaft, and stirring blades. The output shaft of the stirring motor is connected to the stirring shaft, and the stirring blades are installed at the end of the stirring shaft.

[0011] The filling-pushing cavity is connected to one side of the lever seat. The filling-pushing cavity is provided with a filling inlet hole on the side of the lever seat. The bottom of the filling-pushing pipe is provided with a filling guide pipe that connects to the filling inlet hole, so that the filling can enter the interior of the filling-pushing cavity along the filling guide pipe.

[0012] The pusher slider has a cavity inside, which includes a sealing section, a limiting section, and an air guiding section. The sealing section has an air vent at its top, which is connected to the compressed air valve. The limiting section has a lateral width greater than the sealing section and the air guiding section. The inner wall of the pusher slider has an air guiding gap at the position of the air guiding section.

[0013] The pneumatic component has a U-shaped air storage recess on its upper part, which can cooperate with the sealing section to form an airtight chamber.

[0014] The pneumatic component has an air guide hole at its lower part, and an air guide pipe is provided inside the air guide hole, which connects to the bottom of the pneumatic component. The compressed air valve can push the pneumatic component and make the air storage recess reach the air guide section. At this time, the air storage recess and the air guide gap overlap. The compressed air can enter the air guide hole along the air guide gap and be sprayed downward along the air guide pipe.

[0015] The pneumatic component has limit stroke holes on both sides of the air storage recess, and a limit pin passes through the limit stroke hole, thereby limiting the up and down movement of the pneumatic component through the limit pin.

[0016] A return spring is connected to the pneumatic component. One end of the return spring is connected to the limiting pin, and the other end is connected to the upper inside of the pushing slider.

[0017] The rotating shaft extends to the side and forms a rotating transmission shaft that is connected to it. The rotating transmission shaft extends and is rotatably mounted on the suspension. The rotating drive device is a drive cylinder mounted on the suspension. The piston rod of the drive cylinder is connected to a spherical joint and drives the rotating transmission shaft to rotate axially through the spherical joint, thereby causing the rotating shaft to rotate inside the lever seat.

[0018] The hopper is provided with a filling box below it, and the bottom of the filling box is provided with a filling feeding channel, which is connected to the filling inlet pipe.

[0019] The filling box is equipped with a transparent cover on top.

[0020] Implementing this utility model has the following beneficial effects: ① The filling injection mechanism can push the filling into the filling cavity, and the filling slider can simultaneously deliver the filling out of the filling cavity. Then, the filling is sprayed out using a compressed air valve and pneumatic components, ensuring that no filling remains in the filling cavity, thus preventing bacterial growth and contamination that could affect product quality. ② The filling slider and pneumatic components allow the high-pressure gas generated by the compressed air valve to accurately spray the filling, avoiding inaccurate feeding. ③ The filling injection mechanism can control the amount of filling entering the filling mechanism, ensuring quantitative and consistent filling, and improving the stability of the finished product.

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, an automatic filling device for an egg dumpling forming machine includes: a filling feeding mechanism 1, a filling filling mechanism 2, and a filling pushing mechanism 3.

[0030] like Figure 2 , Figure 3 As shown, the filling feeding mechanism 1 includes: a hopper 11, a lever base 12, a rotating shaft 13, and a rotating drive device 14. A filling box 111 is provided below the hopper 11, and a filling feeding channel 1111 is provided at the bottom of the filling box 111. The lever base 12 is connected to the bottom of the filling box 111. The lever base 12 is provided with a filling inlet pipe 121, a filling injection pipe 122, and a filling push pipe 123. The filling inlet pipe 121 is connected to the filling feeding channel 1111. The rotating shaft 13 is rotatably disposed inside the lever base 12. A connecting pipe 131 is provided inside the rotating shaft 13. The rotating drive device 14 can drive the rotating shaft 13 to rotate inside the lever base 12, thereby connecting the connecting pipe 131 to the filling inlet pipe 121 and the filling injection pipe 122, or connecting the filling injection pipe 122 and the filling push pipe 123.

[0031] like Figure 3 As shown, the filling mechanism 2 includes: a filling cylinder 21, a fixed plate 22, and an adjusting screw 23. The fixed plate 22 is connected to the lever seat 12 through the adjusting screw 23. The fixed plate 22 is provided with a piston through hole. The piston rod of the filling cylinder 21 passes through the piston through hole and extends into the filling pipe 122, so that when the piston rod performs telescopic movement, positive and negative air pressure can be formed inside the filling pipe 122.

[0032] like Figure 4As shown, the rotating shaft 13 extends to the side and forms a rotating drive shaft 132 that is connected to it for transmission. The rotating drive shaft 132 extends and is rotatably mounted on the suspension 141.

[0033] The rotary drive device 14 is a drive cylinder 142 installed on the suspension 141. The piston rod of the drive cylinder 142 is connected to a fisheye connector 143, and the rotary transmission shaft 132 is driven to rotate axially through the fisheye connector 143, thereby causing the rotary shaft 13 to rotate inside the lever seat 12.

[0034] Please combine Figures 1-4 When the filling enters the filling box 111 along the hopper 11, the filling inlet pipe 121 and the filling delivery channel 1111 are aligned and connected. Therefore, the filling can directly enter the L-shaped connecting pipe 131 inside the rotating shaft 13. When the rotating shaft 13 is at the current rotation angle, the filling inlet pipe 121 and the filling pipe 122 are connected to each other. At the same time, the piston rod of the filling cylinder 21 of the filling mechanism 2 moves away from the lever seat 12, thereby creating a negative pressure in the filling pipe 122. The filling is then sucked into the filling pipe 122 from the filling inlet pipe 121 due to the negative pressure.

[0035] When the filling pipe 122 is filled with filling, the drive cylinder 142 is activated, turning the rotary transmission shaft 132 through the fisheye connector 143, thereby causing the rotary shaft 13 to rotate 90° within the lever seat and connecting the filling pipe 122 and the filling pushing pipe 123. At the same time, the piston rod of the filling cylinder 21 of the filling mechanism 2 moves towards the lever seat 12, squeezing the filling in the filling pipe 122 and forming positive pressure. At this time, the filling enters the filling pushing pipe 123 from the filling pipe 122 along the connecting pipe 131, and then enters the interior of the filling pushing cavity 32 through the filling guide pipe 1231 provided at the bottom of the filling pushing pipe 123.

[0036] like Figure 4 , Figure 5 As shown, the filling pushing mechanism 3 is connected to the lever seat 12 and includes: a filling pushing cylinder 31, a filling pushing cavity component 32, a filling pushing slider 33, and a pneumatic component 34.

[0037] like Figure 5 , Figure 6 and Figure 7As shown, the filling-pushing cylinder 31 is driven by the filling-pushing slider 33, which moves the filling-pushing slider 33 up and down within the filling-pushing cavity 32. The pneumatic component 34 is slidably disposed within the filling-pushing slider 33. The filling-pushing slider 33 is connected to a compressed air valve 35 for pushing the pneumatic component 34. The compressed air valve 35 pumps in compressed air to push the pneumatic component 34 to move inside the filling-pushing slider 33, and the compressed air is released downward along the air guide gap set on the air guide section of the filling-pushing slider, spraying the filling downward.

[0038] The filling-pushing cavity 32 is connected to one side of the lever seat 12. The filling-pushing cavity 32 is provided with a filling inlet hole 321 on the side near the lever seat 12. The bottom of the filling-pushing pipe 123 is provided with a filling guide pipe 1231 that connects to the filling inlet hole 321, so that the filling can enter the interior of the filling-pushing cavity 32 along the filling guide pipe 1231.

[0039] The pusher block 33 has a cavity 331 inside, and the cavity 331 includes: a sealing section 3311, a limiting section 3312 and an air guiding section 3313;

[0040] The sealing section 3311 has a vent at its top, which is connected to the compressed air valve 35. The lateral width of the limiting section 3312 is greater than that of the sealing section 3311 and the air guiding section 3313. The inner wall of the pusher slider 33 has an air guiding gap 345 at the position of the air guiding section 3313.

[0041] The pneumatic component 34 is provided with a U-shaped air storage recess 341 above it, and the air storage recess 341 can cooperate with the sealing section 3311 to form an airtight chamber.

[0042] The pneumatic component 34 is provided with an air guide hole 342 at its lower part. An air guide pipe is provided inside the air guide hole 342, which is connected to the bottom of the pneumatic component 34. The compressed air from the compressed air valve 35 can push the pneumatic component 34 and cause the air storage recess 341 to reach the air guide section 3313. At this time, the air storage recess 341 and the air guide gap 345 overlap. Compressed air can enter the air guide hole 342 along the air guide gap 345 and be sprayed downward along the air guide pipe.

[0043] Specifically, the pneumatic component 34 has limit stroke holes on both sides of the air storage recess 341, and a limit pin 343 passes through the limit stroke holes, thereby limiting the up and down movement of the pneumatic component 34.

[0044] Specifically, a return spring 344 is connected to the pneumatic component 34. One end of the return spring 344 is connected to the limiting pin 343, and the other end is connected to the upper interior of the pushing slider 33.

[0045] Reference Figures 5-7 When the filling enters the filling-pushing cavity 32, the filling-pushing cylinder 31 can drive the filling-pushing slider 33 to move downward in the filling-pushing cavity 32, thereby pushing out the filling below.

[0046] During the ejection process, the compressed air valve 35 can pump compressed air into the pusher slider 33. As the amount of gas increases, the compressed gas forms a positive pressure in the sealed chamber and pushes the pneumatic component 34 downward until the air storage recess 341 of the pneumatic component enters the air guide section 3213. At this time, the air storage recess 341 and the air guide gap 345 overlap. The compressed air can enter the air guide hole 342 along the air guide gap 345 and spray downward along the air guide pipe until the filling falls.

[0047] After the filling is ejected, the compressed air is released, and the air pressure in the airtight chamber is equal to the outside air pressure. At this time, the pneumatic component 34 is pulled back into the sealing section 3311 by the force of the return spring 344 to restore its deformation, waiting for the next round of filling pushing operation.

[0048] Please refer to Figure 1 As a preferred configuration, a stirring device 15 is provided above the hopper 11 via a support frame. The stirring device 15 includes a stirring motor 151, a stirring shaft 152, and stirring blades 153. The output shaft of the stirring motor 151 is connected to the stirring shaft 152, and the stirring blades 153 are installed at the end of the stirring shaft 152. Thus, the filling entering the hopper can be fully stirred by the stirring device 15.

[0049] In addition, in this embodiment, the support frame is also provided with a reflector, so that the stirring of the filling in the hopper and the amount of filling fed into the hopper can be observed through the reflector.

[0050] More preferably, a filling box 111 is provided below the hopper 11, and a filling feeding channel 1111 is provided at the bottom of the filling box. The filling feeding channel 1111 is connected to the filling inlet pipe 121. A transparent cover plate 1112 is provided at the top of the filling box 111, so that the amount of filling in the filling box can be observed.

[0051] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
