Description

Technical Field

[0001] This invention relates to the field of frozen dumpling production equipment technology, and in particular to a frozen dumpling feeding and pushing mechanism. Background Technology

[0002] Quick-frozen dumplings are dumplings that have been wrapped and then frozen to make them easier to refrigerate.

[0003] The entrance to a freezer compartment is usually located at a high position. When quick-freezing dumplings, the trays containing the dumplings need to be manually pushed into the freezer compartment from the entrance. However, because the entrance to the freezer compartment is high, the trays need to be manually lifted during the process of pushing them into the freezer compartment. After a long period of work, this consumes a lot of labor and reduces work efficiency. Moreover, the dumplings are not in a quick-freezing state during the lifting process. If they slip, they will clump together and stick together. If they are then quick-frozen, they will clump together. Summary of the Invention

[0004] In view of this, the present invention provides a quick-frozen dumpling feeding and pushing mechanism to solve the problem that if the dumplings are not in a quick-frozen state during the lifting process, they will clump together and stick together once they slip, and then they will clump together when quick-frozen.

[0005] This invention provides a feeding and pushing mechanism for quick-frozen dumplings, specifically comprising: a supporting base frame; a central support plate horizontally welded to the middle of the four supporting columns of the supporting base frame, and a quick-frozen dumpling conveyor mounted above the central support plate; a rectangular box-shaped feeding and pushing box vertically mounted on the central support plate at the front end of the quick-frozen dumpling conveyor; a vertical feeding frame below the feeding and pushing box; pre-freezing atomizing boxes embedded in the middle of the left and right side walls of the feeding and pushing box; a longitudinal pushing frame fixedly mounted near the upper middle of the front end of the feeding and pushing box; a control box fixedly hung near the front of the right side wall of the central support plate; and a dumpling tray vertically slidably placed inside the inner cavity of the feeding and pushing box.

[0006] Optionally, a self-sealing door is rotatably installed on the lower part of the front side wall of the feeding box via a hinge. A magnetic sticker is affixed to the lower outer wall of the self-sealing door. A stop magnetic plate is fixedly affixed to the feeding box on the lower outer side. The stop magnetic plate and the magnetic sticker have opposite magnetic properties. An indicator light is connected to the lower end of the stop magnetic plate. An indicator light squeeze switch is embedded in the inner cavity of the feeding box at the lower inner side of the self-sealing door. The indicator light squeeze switch is electrically connected to the control circuit of the indicator light. When the indicator light squeeze switch is squeezed, the indicator light lights up. A feeding port is opened at the upper back of the feeding box corresponding to the upper position of the quick-frozen dumpling conveyor. A horizontal docking support plate is provided at the lower edge of the feeding port. The rear end of the docking support plate is seamlessly connected to the front end of the conveyor belt of the quick-frozen dumpling conveyor. Longitudinal limiting strips are provided on the left and right side walls of the inner cavity of the feeding box above the lower edge of the feeding port. A pressure sensor is embedded in the bottom of the limiting strip.

[0007] Optionally, a vertical feeding motor is fixedly installed at the bottom of the feeding frame, and guide rods are vertically upward at the four corners of the upper end of the feeding frame. A lead screw is vertically rotatably installed in the middle of the feeding frame, and the lower end of the lead screw is fixedly connected to the rotating shaft of the feeding motor through a coupling. The upper ends of the four guide rods pass through the middle support plate and are connected to a rectangular support plate. The support plate slides vertically in the inner cavity of the feeding push box. The upper end of the lead screw is screwed through the support plate and rotatably connected to the lower end of the support plate. A pressing protrusion is fixedly installed in the middle of the front end of the support plate. A pressing groove inclined downward and backward is opened in the middle of the pressing protrusion. When the support plate is at the lowest position, the pressing groove presses against the signal light pressing switch.

[0008] Optionally, a pusher electric cylinder is vertically installed at the middle of the outer end of the pusher frame. A pusher plate is fixedly connected to the end of the piston rod of the pusher electric cylinder. The pusher plate is slidably built into the inner cavity of the feeding and pushing box. After the pressure sensor at the bottom of the limit bar is triggered, the piston rod of the pusher electric cylinder is pushed out.

[0009] Optionally, the pre-freezing atomizing box is in an outward and upward inclined insertion state. An atomizing spray base is fixedly encapsulated in the upper part of the inner cavity of the pre-freezing atomizing box. An atomizing buffer box is provided above the atomizing spray base. Atomizing nozzles are distributed on the atomizing spray base at the lower end of the atomizing buffer box. The upper end of the atomizing buffer box is connected to a pre-freezing atomizing gas inlet pipe, and a solenoid valve is provided on the pre-freezing atomizing gas inlet pipe. The solenoid valve opens when the pressure sensor triggers the pressure sensor that drives the feeding motor to move the pallet up to the limit bar. A sunken recovery storage tank is provided at the lower end of the pre-freezing atomizing box. The connection between the recovery storage tank and the feeding pusher box is an inclined structure. A drain pipe is embedded in the lower end of the recovery storage tank.

[0010] This invention provides a feeding and pushing mechanism for quick-frozen dumplings, which has the following advantages: 1. This invention enables dumplings to automatically enter the freezing equipment for freezing, realizing the lifting and transfer of dumplings. Only staff need to be stationed at both ends of the equipment, eliminating the intermediate operation process, saving labor, and pre-freezing can also be carried out during the transfer of dumplings, effectively improving the integrity of the dumplings, avoiding the problem of sticking together, and ensuring the yield of finished dumplings.

[0011] 2. In this invention, the signal light squeeze switch is electrically connected to the signal light control circuit. When the signal light squeeze switch is squeezed, the signal light is lit, which can indicate that the tray is at the bottom position and the dumpling tray can be put in. The self-sealing door can be automatically closed by the magnetic attraction of the stop magnetic plate and the magnetic sticker, which helps to maintain the hygiene inside the feeding box and the pre-freezing effect of the dumplings, and avoids the problem of the dumplings opening and leaking during the conveying and transfer process.

[0012] 3. In this invention, the connection between the recovery storage tank and the feeding and pushing box is an inclined structure. The lower end of the recovery storage tank is embedded with a drain pipe, which can recover the condensate generated by the pre-freezing atomizing box and prevent it from flowing onto the dumpling tray and damaging the dumplings.

[0025] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0026] Please refer to Figures 1 to 9 As shown: Example 1: This invention provides a quick-frozen dumpling feeding and pushing mechanism, including a support base frame 1; a middle support plate 2 is horizontally fixedly welded at the middle position of the four support columns of the support base frame 1, and a quick-frozen dumpling conveyor 3 is provided above the middle support plate 2; a rectangular box-shaped feeding and pushing box 5 is vertically installed on the middle support plate 2 at the front end of the quick-frozen dumpling conveyor 3; a vertical feeding frame 6 is provided below the feeding and pushing box 5; pre-freezing atomizing boxes 8 are respectively embedded in the middle positions of the left and right side walls of the feeding and pushing box 5; a longitudinal pushing frame 7 is fixedly installed at the upper middle position of the front end of the feeding and pushing box 5; a control box 4 is fixedly hung at the front end of the right side wall of the middle support plate 2; and a dumpling tray 9 is vertically slidably placed in the inner cavity of the feeding and pushing box 5.

[0027] The feeding and pushing box 5 has a self-sealing door 501 mounted on the lower part of the middle of its front side wall via a hinge. A magnet 50101 is attached to the lower outer wall of the self-sealing door 501. A stop magnetic plate 505 is fixedly attached to the lower outer side of the feeding and pushing box 5. The stop magnetic plate 505 and the magnet 50101 have opposite magnetic properties. A signal light 50501 is connected to the lower end of the stop magnetic plate 505. A signal light squeeze switch 506 is embedded in the inner cavity of the feeding and pushing box 5 at the lower inner side of the self-sealing door 501. The control circuit of the pressure switch 506 is electrically connected to the signal light 50501. When the pressure switch 506 is pressed, the signal light 50501 lights up, which can indicate that the tray 604 is at the bottom position and the dumpling tray 9 can be put in. The self-sealing door 501 can be automatically closed by the magnetic attraction of the stop magnetic plate 505 and the magnetic sticker 50101, which helps to maintain the hygiene inside the feeding box 5 and the pre-freezing effect of the dumplings, and avoids the problem of the dumplings opening and leaking during the conveying and transfer process. A feeding port 502 is provided at the upper back of the feeding box 5, corresponding to the upper position of the quick-frozen dumpling conveyor 3. A docking support plate 503 is horizontally provided at the lower edge of the feeding port 502. The rear end of the docking support plate 503 is seamlessly connected to the front end of the conveyor belt of the quick-frozen dumpling conveyor 3. Longitudinal limiting strips 504 are provided on the left and right side walls of the inner cavity of the feeding box 5 above the lower edge of the feeding port 502. A pressure sensor is embedded in the bottom of the limiting strip 504.

[0028] The feeding frame 6 has a vertically mounted feeding motor 601 at its bottom. Guide rods 603 are vertically mounted at the four corners of the upper part of the feeding frame 6, while a lead screw 602 is rotatably mounted vertically upwards in the middle of the feeding frame 6. The lower end of the lead screw 602 is fixedly connected to the shaft of the feeding motor 601 via a coupling. The upper ends of the four guide rods 603 pass through the central support plate 2 and are connected to a rectangular support plate 604. The support plate 604 slides vertically within the inner cavity of the feeding and pushing box 5. The upper end of the lead screw 602 is screwed through the support plate 2 and rotatably connected to the lower end of the support plate 604; a pressing protrusion 60401 is fixedly provided in the middle of the front end of the support plate 604, and a pressing groove 60402 inclined downward and backward is opened in the middle of the pressing protrusion 60401. When the support plate 604 is in the lowest position, the pressing groove 60402 is pressed against the signal light pressing switch 506. At this time, the signal light 50501 can be lit to remind the staff that the dumpling tray 9 can be placed. After 601 is started, the lead screw 602 rotates, driving the feeding frame 6 to move upward through the guide rod 603. The pallet 604 drives the dumpling tray 9 to move upward. At the same time, the solenoid valve 80202 is activated, and the atomizing nozzle 80101 sprays low-temperature gas to pre-freeze the dumplings on the dumpling tray 9. After the dumpling tray 9 comes into contact with the pressure sensor at the lower end of the limit bar 504, the pushing electric cylinder 701 is activated, and the solenoid valve 80202 is closed. At this time, the pushing electric cylinder 701 pushes the dumpling tray 9 from the pallet 604 onto the conveyor belt of the quick-freezing dumpling conveyor 3 through the push plate 702, thus completing one feeding and pushing process of quick-freezing dumplings. This allows the dumplings to automatically enter the freezing equipment for freezing, realizing the lifting and transfer of dumplings. Only personnel need to be arranged at both ends of the equipment, which can save the intermediate operation process and labor. Furthermore, pre-freezing can be carried out during the transfer of dumplings, which effectively improves the integrity of the dumplings and ensures the yield of finished dumplings.

[0029] Among them, a pusher electric cylinder 701 is vertically installed at the middle of the outer end of the pusher frame 7. The piston rod of the pusher electric cylinder 701 is fixedly connected to a pusher plate 702. The pusher plate 702 is slidably built into the inner cavity of the feeding pusher box 5. After the pressure sensor at the bottom of the limit bar 504 is triggered, the piston rod of the pusher electric cylinder 701 is pushed out.

[0030] The pre-freezing atomizing box 8 is in an outward and upward inclined insertion state. An atomizing spray base 801 is fixedly encapsulated in the upper part of the inner cavity of the pre-freezing atomizing box 801. An atomizing buffer box 802 is provided in the upper part of the atomizing spray base 801. Atomizing nozzles 80101 are distributed on the atomizing spray base 801 at the lower end of the atomizing buffer box 802. The upper end of the atomizing buffer box 802 is connected to the pre-freezing atomizing gas inlet pipe 80201, and a solenoid valve 80202 is provided on the pre-freezing atomizing gas inlet pipe 80201. When the feeding motor 601 works, it drives the pallet 604 to move up to the pressure sensor of the limit strip 504, during which the solenoid valve 80202 is opened.

[0031] Example 2: The present invention provides a quick-frozen dumpling feeding and pushing mechanism, which also includes a sunken recovery storage tank 803 at the lower end of the pre-freezing atomizing box 8. The connection between the recovery storage tank 803 and the feeding and pushing box 5 is an inclined structure. The lower end of the recovery storage tank 803 is embedded with a drain pipe 804, which can recover the condensate generated by the pre-freezing atomizing box 8 and prevent it from flowing onto the dumpling tray 9 and damaging the dumplings.

[0032] The specific usage and function of this embodiment: During use, the signal light squeeze switch 506 is electrically connected to the control circuit of the signal light 50501. When the signal light squeeze switch 506 is squeezed, the signal light 50501 lights up, indicating that the tray 604 is at its lowest position and the dumpling tray 9 can be placed in. The self-sealing door 501 automatically closes due to the magnetic attraction of the stop magnetic plate 505 and the magnetic sticker 50101. Longitudinal limiting strips 504 are respectively provided on the left and right side walls of the inner cavity of the feeding box 5 above the lower port of the feeding port 502. A pressure sensor is embedded in the bottom of the limiting strip 504. A squeezing protrusion 60401 is fixedly provided in the middle of the front end of the tray 604. A squeezing groove 60402 inclined downwards and backwards is opened in the middle of the squeezing protrusion 60401. When plate 604 is at its lowest position, the extrusion groove 60402 is pressed against the signal light extrusion switch 506. At this time, the signal light 50501 can be lit to remind the staff that dumpling tray 9 can be placed. After the feeding motor 601 starts, the lead screw 602 rotates, driving the feeding frame 6 to move upward through the guide rod 603. The pallet 604 drives the dumpling tray 9 to move upward. At the same time, the solenoid valve 80202 is activated, and the atomizing nozzle 80101 sprays low-temperature gas to pre-freeze the dumplings on the dumpling tray 9. After the dumpling tray 9 comes into contact with the pressure sensor at the lower end of the limit bar 504, the pushing electric cylinder 701 is activated, and the solenoid valve 80202 is closed. At this time, the pushing electric cylinder 701 pushes the dumpling tray 9 from the pallet 604 onto the conveyor belt of the quick-freezing dumpling conveyor 3 through the pushing plate 702.
