Description

Technical Field

[0001] The invention relates to the technical field of pre-prepared food processing, and in particular to an automatic feeder for pre-prepared food. Background Art

[0002] "Prepared dishes" are a type of convenient dish that is designed to address the complexities of the preparation process for banquet dishes, wine restaurants and specialty dishes. They use modern standardized assembly line operations to carry out preliminary preparation of dish ingredients, simplify the production steps, and then are hygienically and scientifically packaged, and can then be eaten directly through heating or steaming or frying.

[0003] During the production process, pre-prepared dishes are packaged first and then preserved using rapid freezing technology (minus 18 degrees Celsius) to ensure the freshness and original flavor of the dishes. The current method of loading pre-prepared dishes is to fix the packaging bag on the conveyor belt of the assembly line. The packaging bag is usually fixed by using a clamping structure to clamp the two walls of the open end of the packaging bag, so that it can be fixed while keeping the open end in an open state. The pre-prepared dishes can then be loaded into the packaging bag through the feeding tube.

[0004] Although such a feeding method and bagging method are fast, since the feeding tube is usually located above the conveyor belt of the assembly line, and the clamping position of the fixed packaging bag is at the edge of its open end, and the packaging bag is in an open state, the inner side wall position of the packaging bag will be directly displayed under the feeding tube in an inclined state, which will cause the feeding operation of the pre-prepared dish to generate a direct impact force on the side wall of the packaging bag. In addition, the height difference between the end of the feeding tube of the pre-prepared dish and the packaging bag will cause the edge of the packaging bag to break away from the clamping structure and topple over, which will then cause the pre-prepared dish to spill and be wasted. In view of this, the present invention proposes an automatic feeder for pre-prepared dishes. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Automatic feeder for pre-prepared dishes, reference Figure 1-11 , comprising a base 1, a conveying assembly 2 is installed inside the base 1, the conveying assembly 2 is similar to the effect of a conveyor belt in an existing assembly line operation, a shell 3 is inserted on one side of the top surface of the base 1, a through hole 4 is opened at the lower part of the shell 3, the two side ends of the bottom surface of the through hole 4 are flush with the top surface of the base 1, a cavity 5 is opened on the top surface of the through hole 4, a material discharge assembly 6 is arranged inside the cavity 5, and the material discharge assembly 6 is used to fill the pre-prepared food into the packaging bag;

[0039] The material discharge assembly 6 includes a bellows 7 fixedly provided in the middle of the top surface of the cavity 5. The bellows 7 can be retracted to adapt to the up and down movement of the lifting seat 9. A feed pipe 8 is penetrated through the middle of the top surface of the shell 3. The end of the feed pipe 8 away from the shell 3 is connected to the output end of the external feeding device. The diameter of the end of the feed pipe 8 that penetrates into the cavity 5 is larger than the end of the feed pipe 8 connected to the external feeding device. The two ends are connected by a truncated cone-shaped pipe. The lower part of the bellows 7 is connected to the lifting seat 9. The lifting seat 9 is a mouth-shaped structure with the open end facing the upper and lower sides. The lifting seat 9 can move up and down. Two sealing plates 10 are symmetrically slidably connected to the two sides of the lifting seat 9. The sealing plates 10 can be slidably connected to the lifting seat 9 along The sealing plate 10 is slidably connected to the inner wall of the cavity 5, and the sealing plate 10 will also move up and down with the lifting seat 9. The outer wall of the sealing plate 10 is slidably connected with a movable plate 11, and the inner end of the movable plate 11 is a U-shaped rod structure, and the outer end of the movable plate 11 is a trapezoidal column structure. Two hydraulic rods 12 are symmetrically fixed between the top surface of the movable plate 11 and the inner wall of the cavity 5. The lifting seat 9 can be operated by the extension and retraction of the hydraulic rods 12. The hydraulic rods 12 are used to drive the movable plate 11 to move downward. A side groove 13 is provided on the side wall of the sealing plate 10, and two rotating plates 15 are hinged inside the side groove 13 through a hinge shaft 14. The lower ends of the two rotating plates 15 are rotatably connected with a first magnet 1 through a central axis 16. 7. Two support plates 18 are symmetrically hinged at the lower part of the lifting seat 9. The first magnet 17 is adsorbed and matched with the side wall of the sealing plate 10. The first magnet 17 is a quadrangular prism structure. Such a structure can make the first magnet 17 and the support plate 18 have a larger fitting surface when adsorbed. Compared with a columnar magnet, such a structure can produce a greater clamping force. In this way, when the support plate 18 rotates to expand the opening end of the packaging bag, the first magnet 17 can give a certain clamping force to the side of the opening end of the packaging bag, so that the impact force generated in the process of pouring the pre-prepared food into the packaging bag cannot easily knock down the packaging bag. At the same time, because the lifting seat 9 is lowered, the filling height of the pre-prepared food will also be reduced to avoid a high drop. The amplification of the impact force further reduces the possibility of the packaging bag being knocked over. A pull plate 19 is rotatably connected between the outer wall of the support plate 18 and the bottom surface of the sealing plate 10. When the lifting seat 9 descends, the two sealing plates 10 will descend accordingly. Because they are slidably connected to the front and rear walls of the cavity 5 through the movable plate 11, and they are slidably connected to the movable plate 11, the front and rear sealing plates 10 can be separated from the front and rear sides, thereby opening a passage between the upper and lower sides of the lifting seat 9. Subsequently, the pre-prepared food input into the feed pipe 8 through the external feeding mechanism will enter the lifting seat 9 from the inside of the bellows 7, and then pass through between the two sealing plates 10 and be poured into the packaging bag from the lower opening end of the lifting seat 9;

[0040] A fixing assembly 20 is provided inside the through-port 4, and the fixing assembly 20 is used to fix the packaging bag, and the fixing assembly 20 can rotate with the conveying assembly 2. The fixing assembly 20 includes a moving seat 21, and a vertical groove 49 is provided on the side wall of the through-port 4 to slide with the moving seat 21. The moving seat 21 can move up and down or forward and backward inside the through-port 4. A sleeve 22 is fixed on the top surface of the moving seat 21. The sleeve 22 can limit the space on both sides of the packaging bag, exert a certain supporting force on its side wall, and hold the packaging bag containing pre-prepared dishes to avoid the occurrence of dumping problems. Four fixing rods 23 are symmetrically fixed on the upper end of the inner wall of the sleeve 22. The fixing rods 23 are L-shaped structures, and the bottom surface of the fixing rods 23 is elastically connected with a clamping plate 24. Two second magnets 2 are symmetrically embedded at both ends of the top surface of the moving seat 21. 5. A third magnet 26 that is attracted and matched with the second magnet 25 is embedded in the middle of the top surface of the vertical groove 49. When the movable seat 21 fixed with no pre-prepared food packaging bag is moved to the inside of the through-hole 4, the second magnet 25 and the third magnet 26 are attracted to each other. At this time, the light movable seat 21 and the structure thereon will be sucked into the upper part of the vertical groove 49. In the subsequent process of filling the pre-prepared food, if the pressure exerted on the movable seat 21 by the weight of the pre-prepared food in the packaging bag is greater than the suction force of the third magnet 26, the movable seat 21 will fall down again and be driven out of the housing 3 by the metal soft rope 31. This design can not only accurately control the pre-prepared food filled in each packaging bag, but also further reduce the drop of the pre-prepared food poured into the packaging bag, and further reduce the impact force generated by the unloading of the pre-prepared food.

[0041] A sensing mechanism 27 is also disposed inside the through opening 4 , and the sensing mechanism 27 is used to control the extension of the hydraulic rod 12 after the moving seat 21 reaches a specified position.

[0042] Specifically, refer to Figure 1-11 The conveying assembly 2 includes a motor 28 fixedly mounted on the side wall of the base 1, and the motor 28 is connected to an external power supply through an electric wire. A circular cavity 29 is opened inside the base 1 relative to the output end of the motor 28, and two winding wheels 30 are sleeved on the output end of the motor 28. The winding wheels 30 rotate in cooperation with the circular cavity 29, and a metal soft rope 31 is wound around the middle of the winding wheel 30. The metal soft rope 31 is spirally wound around the middle of the outer wall of the winding wheel 30. The winding wheel 30 is an I-shaped cylinder, which can prevent the metal soft rope 30 from slipping out from the side. Both ends of the metal soft rope 31 penetrate the top surface of the circular cavity 29 and extend to the outside and are slidably connected to the base 1. The positions where the ends of the two sides of the metal soft rope 31 penetrate the top surface of the circular cavity 29 are on the same longitudinal straight line, and the distance between the two is much smaller than the longitudinal width of the moving seat 21. The metal soft rope 31 is used to drag the moving seat 21 to move along the top surface of the base 1 for turnover.

[0043] For further reference, Figure 1-11A first rope groove 32 is provided on the top surface of the base 1, and the bottom surface of the through-opening 4 is an isosceles trapezoidal column structure. A second rope groove 33 is provided on the bottom surface of the through-opening 4 relative to the position of the metal soft rope 31. The two ends of the metal soft rope 31 are connected and fixed to form an annular structure and slide with the first rope groove 32 and the second rope groove 33. The first rope groove 32 and the second rope groove 33 are both two-thirds cylindrical structures, which can prevent the metal soft rope 31 from escaping from the restrictions of the two, so that it can stably rotate along the top surface of the base 1. A positioning groove 34 is provided on the bottom surface of the movable seat 21 relative to the position of the metal soft rope 31. The positioning groove 34 can help the staff quickly determine the position where the movable seat 21 should be placed, so as to avoid the problem that the movable seat 21 is deflected and cannot enter the through-opening 4.

[0044] Further, refer to Figure 1-11 The upper part of the lifting seat 9 is an inverted ladder structure, so that the gap between the upper inner wall of the lifting seat 9 and the sealing plate 10 can form a labyrinth sealing structure to prevent the pre-prepared food from flowing out from the joint. The lifting seat 9 is provided with a plate groove 35 that slides with the sealing plate 10. The inner wall of the plate groove 35 is embedded with a sliding sealing ring 36. The sliding sealing ring 36 can prevent the pre-prepared food temporarily stored in the lifting seat 9 from leaking out of the plate groove 35. The sliding sealing ring 36 is in friction contact with the sealing plate 10. The sliding sealing ring 36 is equivalent to the structure of a piston. Even if the sealing plate 10 moves, the sealing effect can be achieved. One side of the sealing plate 10 is inside A plug plate 37 is fixed to the wall, and a slot 38 that is plugged into and cooperates with the plug plate 37 is opened on the sealing plate 10 on the other side. The two can form a labyrinth sealing structure. In this way, when the two sealing plates 10 do not slide outward, the connection position between the two will be sealed, and the pre-prepared dishes will not be able to drip downward, further reducing the occurrence of waste. A funnel 39 is fixed to the lower end of the lifting seat 9, so that the pre-prepared dishes poured into the packaging bag from the inside of the lifting seat 9 are concentrated in the central position, which is for avoiding spillage and reducing the contact between the pre-prepared dishes and the inner side wall of the packaging bag, further improving the effect of the device in preventing the packaging bag from tipping over.

[0045] Further, refer to Figure 1-11 The lower end of the sealing plate 10 is in a T-shaped structure, and two sliders 40 are symmetrically fixed at the lower ends of the outer walls on both sides of the sealing plate 10. The sliders 40 are hemispherical structures, and the inner wall of the cavity 5 is provided with a slide groove 41 that slidably cooperates with the slider 40. The slide groove 41 is an inclined curved structure with a high inside and a low outside. The movable plate 11 is slidably connected to the side wall of the cavity 5. Under the sliding cooperation of the two, when the lifting seat 9 descends, the sealing plate 10 will be squeezed outward under the curve effect of the slide groove 41. In this way, the dual effects of the descent of the lifting seat 9 and the outward movement of the sealing plate 10 can be achieved without the interference of external force. Conversely, a linkage effect can also be produced, making the operation of the device more coherent and more convenient to use.

[0046] Further, refer to Figure 1-11The inner wall of the side groove 13 is inclined and fits tightly with the inner wall of the rotating plate 15. Such a structural design makes the maximum rotation angle of the rotating plate 15 toward the inner side limited by the side groove 13, so that there is a certain gap between the outer wall and the first magnet 17 when the support plate 18 rotates to the innermost end, so that the first magnet 17 will not continue to clamp the open end of the packaging bag when the movable seat 21 descends, thereby preventing damage to the packaging bag. Two torsion springs 42 are symmetrically sleeved on the outside of the hinge shaft 14, and the two ends of the torsion spring 42 are respectively connected and fixed to the side wall of the rotating plate 15 and the inner wall of the side groove 13. When the support plate 18 is flipped outward, the first magnet 17 will be pushed to rotate outward. When the support plate 18 rotates again, the rotating plate 15 connected with the first magnet 17 will also quickly return to its original position through the rotational force of the torsion spring 42.

[0047] It is worth mentioning that reference Figure 1-11 The support plate 18 is a mountain-shaped structure, and the first magnet 17 is a quadrangular prism structure. Because the first magnet 17 is rotatably connected to the rotating plate 15 through the central axis 16, the support plate 18 can push the first magnet 17 to rotate so that its flat surface can be closely attached to the outer wall of the support plate 18 and clamp the opening end of the packaging bag through adsorption force. The pull plate 19 is arranged in an inclined structure, and the inner side end of the pull plate 19 is rotatably connected to a sliding seat 43. The two sliding seats 43 on the same side are respectively slidably connected to the outer walls of the ends of the support plate 18 on both sides, and the lifting seat When the lifting seat 9 is lowered, the sealing plate 10 will move outward, and then the sealing plate 10 will pull the supporting plate 18 through the pulling plate 19 and make the supporting plate 18 also open outward along the position where it is rotatably connected to the lifting seat 9. The sliding seat 43 is a U-shaped structure, and a groove body that slides with the sliding seat 43 is provided on the side wall of the supporting plate 18. This structure is set to reduce the swing range of the supporting plate 18 to avoid the supporting plate 18 from expanding too much due to the sealing plate 10 opening the internal passage of the lifting seat 9 and moving too far, thereby preventing it from breaking the packaging bag.

[0048] It is worth mentioning that the reference Figure 1-11The lower edge of the vertical groove 49 is an arc structure, and the upper part of the sleeve 22 is a trumpet-shaped structure with a larger top and a smaller bottom. This not only makes it convenient for the staff to fix the packaging bag to the inner side of the sleeve 22, but also provides enough space for the support plate 18 to open the opening end of the packaging bag. The distance between the two fixing rods 23 on the same side in the horizontal direction is greater than the width of the raised end in the middle of the support plate 18. This design is to prevent the fixing rod 23 from hindering the rotation of the support plate 18. A limit block 44 is fixed on the top surface of the clamping plate 24, and a limit groove 45 is provided on the bottom surface of the fixing rod 23 to slide with the limit block 44. The limiting grooves 45 are all T-shaped structures, and a compression spring 46 is fixed between the limiting block 44 and the limiting groove 45. Such a structure can preliminarily fix the open end of the packaging bag, and then the clamping plate 24 can also move along with the process of the support plate 18 opening the open end of the packaging bag. When the support plate 18 returns to its original position, the clamping plate 24 can re-clamp the open end of the packaging bag, and cooperate with the sleeve 22 to support the packaging bag containing pre-prepared dishes. The fixing component 20 can continuously prevent the packaging bag from leaking and tipping over after the unloading operation is completed, thereby ensuring to the greatest extent that the pre-prepared dishes in the packaging bag will not leak out.

[0049] It is worth noting that reference Figure 1-11 The sensing mechanism 27 includes a pressure sensor 47 embedded in the side wall of one of the vertical slots 49. The end of the pressure sensor 47 penetrates the side wall of the vertical slot 49 and extends to the inside of the through-port 4 and is squeezed and matched with the side wall of the moving seat 21. The pressure sensor 47 is electrically connected to the multiple hydraulic rods 12 through multiple wires 48. The middle parts of the multiple wires 48 are commonly connected to a control box 50. After the moving seat 21 rises along the vertical slot 49, its edge position will squeeze the output end of the pressure sensor 47, and then the pressure sensor 49 will transmit the detected pressure to the single-chip microcomputer arranged inside the control box 50 through the wire 48. Subsequently, under the action of the program burned on the single-chip microcomputer, the multiple hydraulic rods 12 will extend to push the lifting seat 9 down.

[0050] Working principle: When using this device, the staff can place the packaging bag for packaging pre-prepared dishes in the fixed component 20 and clamp its open end, and then use the positioning groove 34 on the movable seat 21 to correspond to the position of the two metal soft ropes 31, and then the movable seat 21 will rotate under the drive of the motor 28 on the winding wheel 30. When it moves to the position of the shell 3, it will enter the through-hole 4 along the inclined structure on the bottom of the through-hole 4. The second magnet 25 thereon is attracted by the third magnet 26 to drive the movable seat 21 to lift as a whole, and then the movable seat 21 will trigger the sensing mechanism 27 to control the extension of multiple hydraulic rods 12, and then the unloading component 6 can pour the pre-prepared dishes temporarily stored in the lifting seat 9 and the bellows 7 into the packaging bag through the funnel. In addition, the staff can place multiple fixed components 20 with packaging bags fixed on them at equal intervals on the conveying component 2 according to a certain spacing, and then the effect of automatic filling can be achieved.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
