Description

Technical Field

[0001] The invention relates to the technical field of automatic cooking equipment, in particular to a film cutting and feeding device for an automatic cooking machine. Background Art

[0002] With the gradual promotion and application of automatic cooking equipment such as automatic cooking machines, people are increasingly concerned about the device for removing the film from the material box and automatically feeding the material.

[0003] Most existing film-removing and feeding devices for automatic cooking machines use a film-tearing mechanism to feed the ingredients. These mechanisms typically involve a motor-driven rotating shaft to rotate and tear the film. These film-tearing mechanisms have the following drawbacks: The shaft and other components are exposed to the upper surface of the pot for extended periods, which can easily accumulate grease over time. This affects both the stability of the film-tearing process and the hygiene of the dishes, while also increasing the workload of removing the grease. Furthermore, these film-tearing mechanisms require the edge of the film to be secured to the shaft before use, requiring manual intervention to secure the film to the container. This creates a negative user experience when manually securing the edge of the film.

[0004] Some existing film-cutting and feeding devices for automatic cooking machines use film-cutting to feed the food. Typically, a motor, driven by gears, drives a slider equipped with a blade to move along a guide rail. These film-cutting devices have the following drawbacks: They typically require separate cutting devices for both the X and Y directions, resulting in a relatively complex structure with numerous components. Furthermore, the blades are typically exposed, which can easily accumulate oil and dirt, affecting the stability of the film-cutting process and the hygiene of the food. They also increase the workload of removing oil and dirt, and pose a safety hazard.

[0005] The above two types of existing technologies have a common shortcoming: the film tearing device or the film cutting device requires a fixed frame or a mounting frame to be set on the top surface of the cooking pot body, and the frame must span the diameter of the cooking pot body in both directions and extend out of the edge of the pot, that is, the area and volume are large, and the space occupied is relatively large; the frame located above the cooking pot body is also prone to accumulate oil and dirt, which affects the working stability, affects the hygiene of the dishes, and increases the workload of removing the oil and dirt. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a film cutting and feeding device for an automatic cooking machine which does not require manual intervention in the film removal process, can ensure the hygiene of dishes, and has a relatively simple structure and a relatively small volume.

[0007] The technical solution of the present invention is to provide a film cutting and feeding device for an automatic cooking machine, including a material box that is covered and detachably fixed to the top of the pot body, and a plurality of partitions radiating from the center to the periphery divide the material box into a plurality of triangular cavities of the same size; one side of the pot body of the automatic cooking machine is provided with a fixing frame with a pair of guide grooves; the fixing frames at the outer ends of the pair of guide grooves are each provided with a linear drive mechanism, the driving ends of the pair of linear drive mechanisms are connected to the outer ends of a pair of sliding rods that slide in their respective slide grooves, and the inner ends of the pair of sliding rods are equipped with film cutting knives for linear reciprocating motion along the inner sides of each two adjacent partitions to cut the film on the bottom surfaces of the two partitions and make the material in the triangular cavity fall into the pot body.

[0008] After adopting the above structure, the film cutting and feeding device for the automatic cooking machine of the present invention has the following advantages:

[0009] Since the material box cover is fixed to the top of the pot body in a detachable manner and a fixing frame is provided on one side of the pot body, except for the inner end of the sliding rod extending into the top of the pot body and some parts of the film cutting knife, there is basically no oil accumulation on the outer end of the fixing frame and the sliding rod, which greatly reduces the interference of oil and water vapor, can not only ensure the stability and reliability of the film cutting process, but also greatly reduce the impact of oil on the hygiene of dishes and the workload of removing oil.

[0010] Since the film cutting process of this film cutting and feeding device does not require human intervention, customers have a relatively good psychological experience when using it.

[0011] Since the film cutting and feeding device does not require a large-area and large-volume fixing frame or mounting frame to be set on the top of the cooking machine pot body, but only requires a small-area and small-volume fixing frame to be set on one side of the pot body, it has the advantages of the first point mentioned above, and at the same time has the advantages of small area, small volume and relatively small space occupied.

[0012] Furthermore, the sliding rod is an inner and outer rectangular sleeve; the inner end of the outer rectangular tube is provided with a first end plate, and the top plate of the inner end of the outer rectangular tube is provided with a rectangular long through hole extending along the length direction and used for the film cutting knife to extend, and the inner end surface of the first end plate is a guide surface for the film cutting knife to extend upward; the inner end of the inner rectangular tube is provided with a second end plate, and the second end plate is hinged to one end of the film cutting knife, and the free end of the film cutting knife is a blade; the film cutting knife is horizontally lying in a retracted state inside the outer rectangular tube or in a cutting state with the blade extending from the top end of the outer rectangular tube. After adopting the above structure, the inner and outer rectangular sleeves, under the driving force of the linear drive mechanism and the guide surface at the inner end of the outer rectangular tube, cause the blade or the cutting edge to extend upward from the rectangular through hole of the outer rectangular tube and move straight inward to cut the film; and when the linear drive mechanism pulls back, the inner rectangular tube drives the film cutting knife to retract to lie horizontally in the outer rectangular tube and automatically hide the blade or the cutting edge, which not only ensures that the blade can cut the film flexibly, stably and reliably when it moves straight inward, but also hides the blade or the cutting edge or the blade in the outer rectangular tube when the blade is not in use and moves straight outward through the inner and outer rectangular sleeves, avoiding the blade or the cutting edge being exposed to injure people and accumulate oil stains, and avoiding the safety hazards that may be caused by the exposed blade.

[0013] Furthermore, the second end plate features a pair of vertical lugs. The film cutter is curved, with the free end of the arc serving as a blade. A horizontal first circular hole is located at the connection between the curved and vertical lugs. Each vertical lug features a second horizontal circular hole. A hinge passes through each of the three circular holes and is axially limited. This design makes the hinge more flexible, stable, and reliable. The curved shape of the film cutter allows for more flexible, quick, and smooth raising and retraction.

[0014] Furthermore, the linear drive mechanism is a push-pull electromagnet, the movable slide of the push-pull electromagnet is connected to the outer end of the inner rectangular tube, and a tension spring connects the outer shell of the push-pull electromagnet to the outer end of the outer rectangular tube; the inner and outer rectangular sleeves are in a state where the static iron core of the push-pull electromagnet is energized and repel the magnet of the movable slide to push the blade of the film cutting knife of the inner rectangular tube to extend upward, thereby driving the outer rectangular tube to move linearly inward and cut the film, or in a state where the static iron core of the push-pull electromagnet is de-energized and has the properties of iron, and attracts the magnet of the movable slide to pull the blade of the film cutting knife of the inner rectangular tube to retract and pull the outer and inner rectangular tubes linearly outward through the tension spring. After the linear drive mechanism adopts the above specific structure, its structure is simple, the cost of the drive mechanism is relatively low, and the electricity cost of the film cutting process is relatively low, ensuring that the blade is flexible, stable and reliable when moving linearly back and forth.

[0015] Furthermore, the fixing frame is not fixed to the pot body but to the frame of the automatic cooking machine or the stove; the pot body is fixed to the frame of the automatic cooking machine. With the above structure, the fixing frame itself is stable and reliable, and the pot body is also stable and reliable. In this way, when the film cutting and feeding device, the pot body and the material box move or move relative to each other in a straight line, the working flexibility, stability and reliability are improved.

[0016] Furthermore, the pot body is circular, and the container is a circular container of the same size as the top of the pot body. The bottom of the circular container is provided with multiple pairs of notches for accommodating two pairs of sliding rods. With this structure, the pot body and container are more conveniently secured and removably secured, providing a better sealing effect and facilitating the rotation around the center described below.

[0017] Furthermore, the film cutting and feeding device for an automatic cooking machine of the present invention includes a lifting and rotating device that lifts the circular material box, rotates it coaxially with the circular pot body, and then lowers it so that the adjacent pair of notches align with the pair of sliding rods; the detachable fixation is a press-fit fixation of the lifting and rotating device. With this structure, after cutting the film on the bottom surfaces of the two partitions of a triangular cavity, there is no need for manual rotation and closing of the material box, making the film cutting and feeding device more automated, more convenient and faster to operate, and the closing and detachable fixation more stable and reliable.

[0026] The following is a further description of specific embodiments of the present invention with reference to the accompanying drawings. It should be noted that the description of these specific embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. Furthermore, the technical features involved in the various specific embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 shown.

[0028] The present invention relates to a film cutting and feeding device for an automatic cooking machine. It includes a material box 7, which is covered and removably fixed to the top of a pot body 9. Multiple partitions 13 radiating from the center to the periphery divide the material box 7 into a plurality of triangular cavities 12 of equal size. A fixed frame 20 with a pair of guide slots is provided on one side of the pot body 9 of the automatic cooking machine. Each of the fixed frame 20, located at the outer ends of the guide slots, has a linear drive mechanism. The drive ends of the linear drive mechanisms are connected to the outer ends of a pair of sliding rods that slidably fit within their respective slots. The inner ends of the sliding rods are mounted with a film cutting blade 25 that reciprocates linearly along the inner sides of each pair of adjacent partitions 13, cutting the film from the bottom surfaces of the partitions 13, i.e., the bottom surfaces of the triangular cavities 12, and allowing the material within the triangular cavities 12 to fall into the pot body 9. It will be appreciated that a recessed step 17 can be provided on the fixed frame 20 at the outer ends of the guide slots, and the housing 3 of the linear drive mechanism, such as the push-pull electromagnet 11 described below, can be located on the recessed step 17. A film cutting knife 25 is mounted on the inner end of each sliding rod.

[0029] The fixing frame 20 can be a fan-shaped frame, and the two straight sides of the fan-shaped frame are horizontal rectangular guide bodies 10 that are angled with each other. The rectangular guide body 10 is provided with a rectangular guide groove 6 with an upward opening. The two rectangular guide bodies 10 are connected by a horizontal arc-shaped connector 1, and the cross-sectional shape of the arc-shaped connector 1 can be rectangular.

[0030] The angle between the two partitions 13, that is, the angle between the two sliding rods (such as the inner and outer rectangular sleeves 5 described below) can be 45°-72°, preferably 60°.

[0031] The sliding rod is preferably an inner and outer rectangular sleeve 5. The inner end of the outer rectangular tube 16 is provided with a first end plate 27. The top plate 29 at the inner end of the outer rectangular tube 16 has a rectangular long through hole 28 extending in the longitudinal direction and for the film cutting knife 25 to extend. The inner end surface of the first end plate 27 is a guide surface 30 for the film cutting knife 25 to extend upward. The guide surface 30 can be an arcuate surface or an inclined surface inclined upward. The inner end of the inner rectangular tube 18 is provided with a second end plate 22. The second end plate 22 is hinged to one end of the film cutting knife 25. The free end of the film cutting knife 25 is a blade 26. The film cutting knife 25 is in a retracted state lying horizontally in the outer rectangular tube 16 or in a cutting state with the blade 26 extending from the top of the outer rectangular tube 16, such as above the top plate 29.

[0032] The hinge preferably has the following specific structure: a pair of vertical ear plates 23 are provided on the second end plate 22, the film cutting knife 25 is arc-shaped, the free end of the arc is a blade 26, a first horizontal circular through hole is provided on the connecting end of the arc and the vertical ear plate 23, i.e., the outer end, and the two vertical ear plates 23 have respective second horizontal circular through holes 24, a hinge shaft 19 passes through the three circular through holes, i.e., a first circular through hole and two second circular through holes 24, one by one, and is axially limited. The inner and outer rectangular sleeves 5 can also be replaced by inner and outer circular sleeves, but are preferably inner and outer rectangular sleeves 5. The axial limit of the hinge shaft 19 can be that one end of the hinge shaft can be a shaft shoulder or a big head, and the other end of the hinge shaft can be provided with a cotter pin. The circular through hole is also called a circular through hole.

[0033] A specific embodiment of the linear drive mechanism is a push-pull electromagnet 11, which can be commercially available. A movable slide 21, or push-pull rod, of the push-pull electromagnet 11 is connected to the outer end of the inner rectangular tube 18, and a tension spring 4 connects the outer housing 3 of the push-pull electromagnet 11 to the outer end of the outer rectangular tube 16. The inner and outer rectangular sleeves 5 are either in a state where the static iron core of the push-pull electromagnet 11 is energized and repel the magnet of the movable slide 21, pushing the blade 26 of the film cutting knife 25 of the inner rectangular tube 18 upward, thereby moving the outer rectangular tube 16 linearly inward and causing the blade 26 to cut the film; or in a return state where the static iron core of the push-pull electromagnet 11 is de-energized and attracts the magnet of the movable slide 21, pulling the blade 26 of the film cutting knife 25 of the inner rectangular tube 18 inward and, through the tension spring 4, pulling the outer and inner rectangular tubes 16 linearly outward. In other words, when the static iron core of the push-pull electromagnet 11 is energized and repels the magnet of the movable slide bar 21 with the same polarity to push the blade 26 of the inner rectangular tube 18 to extend upward and thereby drive the outer rectangular tube 16 to move linearly inward, the inner and outer rectangular sleeves 5 are in a state where the blade 26 of the film cutting knife 25 is cutting the film; and when the static iron core of the push-pull electromagnet 11 is de-energized and has the properties of iron, it is attracted to the magnet of the movable slide bar 21 to pull the blade 26 of the film cutting knife 25 of the inner rectangular tube 18 to retract and pull the outer rectangular tube 16 and the inner rectangular tube 18 to move linearly outward through the tension spring 4, the inner and outer rectangular sleeves 5 are in a return state, and at this time the film cutting knife 25 is located inside the outer rectangular tube 16.

[0034] Another specific embodiment of the linear drive mechanism may be an electric push-pull rod, which is also called an electric push rod, and a commercially available electric push rod may be used. The movable rod of the electric push rod, or the push-pull rod, is connected to the outer end of the inner rectangular tube, and a tension spring connects the outer shell of the electric push rod to the outer end of the outer rectangular tube. One end of the tension spring connected to the outer rectangular tube may be connected via a rectangular connecting block. The inner and outer rectangular sleeves are in a state where the coil of the electric push rod is energized and the movable rod pushes the blade of the film cutting knife of the inner rectangular tube to extend upward, thereby driving the outer rectangular tube to move linearly inward and cut the film, or in a return state where the coil of the electric push rod is energized and the movable rod pulls the blade of the film cutting knife of the inner rectangular tube inward, and the tension spring pulls the outer and inner rectangular tubes to move linearly outward. In other words, when the coil of the electric push rod is energized and the movable rod pushes the blade of the film cutting knife of the inner rectangular tube to extend upward and then drives the outer rectangular tube to move linearly inward, the inner and outer rectangular sleeves are in a state where the blade of the film cutting knife is cutting the film; and when the coil of the electric push rod is energized and the movable rod pulls the blade of the film cutting knife of the inner rectangular tube inward and pulls the outer rectangular tube and the inner rectangular tube to move linearly outward through the tension spring, the inner and outer rectangular sleeves are in a return state, and at this time the film cutting knife is located inside the outer rectangular tube.

[0035] Another specific embodiment of the linear drive mechanism can be a pneumatic cylinder, which can be commercially available. The free end of the cylinder piston rod is connected to the outer end of the inner rectangular tube, and a tension spring connects the cylinder housing to the outer end of the outer rectangular tube. The inner and outer rectangular tubes are either in a state where the cylinder piston rod extends, pushing the blade of the inner rectangular tube's film cutting knife upward, thereby driving the outer rectangular tube to move linearly inward and cut the film, or in a return state where the cylinder piston rod retracts, pulling the blade of the inner rectangular tube's film cutting knife inward and, via the tension spring, pulling the outer and inner rectangular tubes linearly outward. In other words, when the piston rod of the cylinder extends and pushes the blade of the film cutting knife of the inner rectangular tube to extend upward and thereby drives the outer rectangular tube to move linearly inward, the inner and outer rectangular sleeves are in a state where the blade of the film cutting knife is cutting the film; and when the piston rod of the cylinder retracts and pulls the blade of the film cutting knife of the inner rectangular tube to retract and pulls the outer rectangular tube and the inner rectangular tube to move linearly outward through the tension spring, the inner and outer rectangular sleeves are in a return state, and at this time the film cutting knife is located inside the outer rectangular tube.

[0036] The fixing frame 20 may not be fixed to the pot body 9 but may be fixed to the frame of the automatic cooking machine or to the stove; the pot body 9 may be fixed to the frame of the automatic cooking machine.

[0037] The pot body 9 is circular, and the container 7 is a circular container of the same dimensions as the top of the circular pot body. The bottom of the circular container is provided with multiple pairs of notches for accommodating two pairs of sliding rods, such as rectangular notches 14 for accommodating outer rectangular tube 16. Only two of these rectangular notches 14 are shown schematically; the remaining rectangular notches are not shown. While it is readily apparent that a polygonal pot body, such as an octagonal, decagonal, or dodecagonal, could also be used, a circular pot body is preferred. Polygonal containers, such as an octagonal, decagonal, or dodecagonal, could also be used, but a circular container is preferred.

[0038] The film cutting and feeding device of the automatic cooking machine of the present invention may also include a lifting and rotating device that lifts the circular material box, rotates it coaxially with the circular pot body, and then puts it down, aligns a pair of adjacent rectangular notches with a pair of sliding rods such as an outer rectangular tube, and presses the material box as described below, such as: including a lifting and rotating bracket fixed to a fixed frame, the lifting and rotating bracket is located directly above the material box, a rotating motor is provided on the lifting and rotating bracket, a turntable coaxially provided on the rotating motor, a lifting motor is fixed on the turntable, a screw rod of a nut and screw rod pair is coaxially connected to the lifting motor shaft, the nut of the screw rod and nut pair is fixed on the lifting and rotating bracket, and the bottom end of the screw rod is fixed with an electric suction cup for adsorbing the top surface of the material box.

[0039] The detachable fixation is preferably a pressing fixation of the lifting and rotating device, such as the electric suction cup at the bottom end of the screw is pressed against the top of the material box.

[0040] The film cutting and feeding device may further include a main controller, and the linear drive mechanisms such as the push-pull electromagnet 11, the rotating motor, the lifting motor and the electric suction cup are all electrically connected to the main controller and controlled by the main controller.

[0041] It is not difficult to understand that after the plastic wrap on the bottom of the two partitions is cut off, it is still adhered to the bottom surface 15 of the curved edge of the material box 7 and can be blown out of the material box 7 by the hot air in the pot body 9 after being lifted by the lifting and rotating device or manually. After all the materials in the material box 7 are put into the pot body 9, they are taken away together with the material box 7.

[0042] The other side of the pot body 9 away from the fixing frame 20 can be provided with a handle 8 or a handle for facilitating the lifting of the pot body 9. The triangular cavity 12 can also be called a triangular space. The connection described above can be welding or the like.

[0043] The above unmarked parts, structures, quantities, etc. are not shown in the drawings. The drawings are for illustration only. If there is any inconsistency between the drawings and the text description or between the drawings, the text description shall prevail.

[0044] Automatic cooking machines are also called automatic cooking machines. Therefore, if there is a device with the same structure as the above film cutting and feeding device for automatic cooking machines of the present invention, but it is not used in automatic cooking machines but in "automatic cooking machines", it also falls within the protection scope of the present invention.

[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
