Description

Technical Field

[0001] The present invention relates to the technical field of automated barbecue, and in particular to an intelligent barbecue device based on dynamic revolution-rotation coupling. Background Art

[0002] Problems with traditional baking uniformity: Traditional equipment uses a single rotation mode and cannot generate heat convection through three-dimensional compound motion, resulting in local carbonization of the food and the coexistence of rawness in the center.

[0004] The integration of the loading and unloading mechanism with the skewer inserter solves the problem of automatic loading and unloading, ensures a continuous baking process, and significantly improves production efficiency. The introduction of the central tube baking design significantly improves heat source utilization efficiency and heat energy distribution uniformity, effectively overcoming the limitations of most existing skewer grills, which are limited to just baking skewers. This broadens the device's scope of application. Adding thermal insulation around the central tube even allows for zoned baking.

[0050] The present invention will be described in further detail below with reference to the accompanying drawings.

[0051] Combined with attachment Figure 1-14 As shown:

[0052] The oven includes an outer frame 1 with an industrial-grade touch display 11 integrated on the front side, through which baking parameters can be monitored in real time and the motion mode can be switched;

[0053] Door assembly: equipped with an insulated door body 31, with a pneumatic auxiliary support rod on the back to achieve the door slow opening function, a double-layer tempered glass window 32 and an anti-scalding door handle 33 embedded on the door body 31;

[0054] An automatic discharge port 4 is provided at the bottom of the outer frame 1, and a central baking tube outlet flap 611 is provided at the left end of the equipment.

[0055] During operation, the conveyor belt 42 is made of food-grade material and features evenly spaced separating protrusions 43 on its surface, forming independent workstation slots. A progressive guide chute 44 is installed at the end, with a certain inclination angle. This allows the skewers to automatically adjust to a predetermined position under the action of gravity, dropping into the attachment 58 that restrains the square end of the skewers. The other end of the skewers, with a rounded end, drops into the hemispherical positioning groove of the driven pulley 6. Ribs 61 are welded between the driving pulley 57 and the driven pulley 6 to transmit power.

[0056] Drive structure:

[0057] The output end of the driving motor 51 is coupled to the central rotating shaft 53 via a speed reducer 52 , and the central rotating shaft 53 realizes torque transmission with the large sprocket 54 and the driving wheel 57 through keyway matching.

[0058] In particular, a detachable support assembly 531 is provided between the central shaft 53 and the planetary gear carrier. The assembly includes an axial positioning bearing assembly and an electromagnetic clutch mounting base 532 to ensure the dynamic balance of the transmission system;

[0059] The large sprocket 54 drives the driven sprocket 55 and the small sprocket 56 of the driven sprocket group through a closed-loop chain 551 to form a transmission chain. Each small sprocket is keyed to form a synchronous rotation pair with the secondary rotating shaft 561. The end of the secondary rotating shaft 561 is connected to the mounting member 58 through a threaded fit to achieve the following compound motion:

[0060] Revolutionary motion: The driving wheel 57 drives the string of sticks to rotate around the central axis;

[0061] Rotational motion: The driven sprocket sets 55 and 56 generate a spinning motion.

[0062] The electromagnetic clutch 59 is axially arranged between the central shaft 53 and the driving wheel, and has two working modes:

[0063] Engaged state: Maintain torque transmission between the central shaft 53 and the driving wheel 57

[0064] Separated state: the mechanical connection between the central shaft 53 and the driving wheel 57 is cut off, and the secondary shaft 561 maintains its self-rotation motion;

[0065] When using:

[0066] When the seasoning process begins, the electromagnetic clutch 59 enters the disengaged state, and the skewers maintain pure rotation when positioned at the top of the gear train, ensuring that the seasoning evenly covers the surface of the food under the action of centrifugal force.

[0067] ② The gear train generates three-dimensional heat convection through compound motion, effectively solving the local overheating problem existing in traditional baking equipment.

[0068] ③The shaft end seal assembly 560 and the shaft sleeve 562 form a double fixed structure to extend the service life of the transmission system

[0069] Through the above modular design, the system realizes the dynamic switching of the skewers' revolution / rotation, and cooperates with the unique motion trajectory of the gear train to make the food heated and spread more evenly.

[0070] In order to achieve the full cycle stable clamping and precise release of the skewers, (such as Figure 7 Part of the driving wheel is hidden to facilitate the display of the structure)

[0071] The support plate 45 is provided with a radial sliding groove inside, and a movable closing card 451 is built in. The card 451 forms an opening and closing transmission with the output shaft of the driving motor 571 through the protrusion 452, and the protrusion 452 is connected to the card 451 through a thread.

[0072] When the strings are pulled up and down, the driving wheel 57 rotates, and the driving motor 571 runs at this time, and its output shaft pushes the sliding protrusion 452 to produce axial displacement, driving the closing card 451 to expand / contract radially along the sliding groove

[0073] When the closing card 451 is closed, it forms a complete limiting ring with the support plate 45. At this time, the limiting card 574 is pressed down by the support plate 45, and a self-locking effect is generated through the wedge-shaped protrusion 572, which constrains the three-dimensional freedom of the square end of the string.

[0074] When the card 451 is opened, the limit card 574 is opened under the action of the torsion spring 573, forming a guide channel to allow the string of labels to slide into the clamping member 58, and the same applies to the blanking end.

[0075] An end positioning mechanism is provided on the right side of the passive wheel 6, and its technical features are:

[0076] The limit card 2 61 adopts a triangular guide structure and is connected to the passive wheel bracket through a rotating shaft.

[0077] When the circular end of the string of sticks contacts the plane of the limit card 61, its gravity component overcomes the preload force of the torsion spring 62, causing the limit card 61 to rotate around the axis to the open position, and the string of sticks accurately falls into the hemispherical damping groove of the passive wheel 6.

[0078] The following structures are included when blanking is used:

[0079] The servo motor 60 is fixed to the side wall of the outer frame 1, and its output shaft is equipped with a paddle 601

[0080] When the roasting is completed, the passive wheel 6 rotates to a preset angle, and the paddle 601 moves in a circular motion to push the circular end of the skewers out of the damping groove.

[0081] The hypotenuse of the triangular limit card 61 and the movement trajectory of the pick 601 form a conjugate relationship, ensuring that the skewers slide out along the tangent direction of the discharge port 4. The triangle can prevent the skewers from getting stuck on the limit card 61 when unloading.

[0082] When the round end of the skewer slides down the conveyor belt and reaches the second stopper 61, gravity compresses the second torsion spring 62, causing the round end of the skewer to fall into the hemispherical positioning groove of the driven wheel 6. The motor 60 is mounted on the outer frame 1. When the grilled food is ready for unloading, the driven wheel rotates to the correct position, the paddle 601 in front of the motor rotates, and the end of the skewer falls into the discharge port 4. The triangular design of the stopper here prevents the end of the skewer from getting stuck when it is lifted.

[0083] When bulk material:

[0084] The high-precision linear guide 25 is fixed to the bottom plate 12 of the equipment, and the composite material spreading box is supported by the slider 26.

[0085] A split vibrating material storage box 23 is installed in the box, and a gradient material dropping channel 231 is opened at the bottom. The end of the channel is connected to an adjustable powder outlet 27. The spreading motor 21 drives the spreading box to perform two-dimensional motion in the plane through the eccentric connecting rod mechanism 22, simulating the random oscillation characteristics of manual spreading.

[0086] Liquid spray module

[0087] The liquid seasoning system includes the following technical features:

[0088] The liquid box 240 is connected to the internal booster pump through a magnetic interface, and the atomizing nozzle 28 is at the outlet end of the pump body, and its spray angle is adjustable.

[0089] Two heating chucks 71 are provided at both ends of the center tube 73, and a plurality of heating tubes 74 are provided in parallel between the chucks. A high-temperature bearing group is provided at the driving wheel end, the inner ring of which is fixed to the center tube 73, and the supporting wheel 710 provides the supporting force of the end. The outer ring is interference-fitted with the driving wheel 57, and the driven wheel end is fixed to the outer frame 1 by welding, thereby ensuring the static state of the center tube 73 and the heating tubes 74, forming a static thermal field basic structure. The center tube (73) contains a baking tray 72 inside, so that corn, sweet potatoes and other ingredients can be baked.

[0090] During the roasting process, the oil dripping from the skewers falls into the oil collecting pan 46. The oil collecting pan (46) has an inclination angle β=8°, and the oil will be quickly discharged from the oil outlet 47.

[0091] The working principle of the present invention is as follows: the automatic loading and unloading mechanism 10 transmits the skewers to achieve precise positioning, the transmission mechanism 20 switches to the revolution-rotation coupling mode, the baking mechanism 40 starts the gradient temperature control program, and the spreading mechanism 30 is responsible for spreading the materials and spraying the liquid.
