[0032] The intelligent cooking machine for continuously serving dishes of the present invention is an intelligent cooking device that can be used in large canteens and can continuously serve hot stir-fried dishes, thereby achieving the continuity of the cooking process and ensuring that the cooked dishes are both fresh and full of flavor, while saving labor and making cooking more intelligent.

[0033] like Figure 1 As shown, the cooking tube 1 has a tunnel-like cooking channel 1, which is shaped like a cylindrical hollow channel. Both ends of the cooking channel 1 are closed end surfaces. An electromagnetic heating device or a resistance wire heating device (not shown in the figure) is arranged on the outer wall of the cooking channel 1 from the head end to the tail end. Figure 1 For example, the top is the top of the cooking pipe 1, the bottom is the bottom of the cooking pipe 1, the left is the head end of the cooking pipe 1, and the right is the tail end of the cooking pipe 1, the same below) is provided near the head end area with a food inlet 11 for various ingredients required for cooking dishes to enter the cooking pipe 1. After the ingredients are cooked in the cooking pipe 1, the cooked dishes are output from the food outlet 12 arranged near the tail end. When the ingredients continuously enter the cooking pipe 1 from the food inlet, the cooked dishes are continuously output from the food outlet 12 accordingly.

[0034] The improvement of the present invention is mainly aimed at the food pushing device arranged in the cooking pipe 1 for pushing the food put into the cooking pipe 1 from the head end to the tail end. The food pushing device includes a pusher 2, a positioning component and a rotating drive device.

[0035] like Figure 2 As shown, the number of the pushers 2 is at least two, and they are arranged in sequence from the head end to the tail end in the cooking pipe 1. Specifically, the pusher 2 includes the rotating drum 21 and a spiral blade 22 arranged on the outer wall of the rotating drum 21 and used to stir-fry and push the ingredients up and down. The rotating drum 21 is cylindrical, and the spiral blade 22 extends from one end of the rotating drum 21 to the other end. The rotating drum 21 is coaxially arranged with the cooking pipe 1.

[0036] The positioning component is relatively fixed to the shell of the cooking pipe 1, and the rotating drum 21 and the rotation driving device are both installed on the positioning component. The rotating drum 21 and the positioning component are driven by the rotation driving device to perform relative rotational motion.

[0037] The rotary drive device is used to realize the reverse rotation of the drums 21 on two adjacent pushers 2 (reverse rotation means that the rotation directions of the two drums are opposite). The rotation speeds of the two adjacent drums 21 can be the same or different, and the spiral directions of the spiral blades 22 on the two adjacent drums 21 are opposite so that when the two drums 21 rotate in reverse, the pushing directions of the dishes are consistent; when the cooking pipe 1 is an uncoated pot, the spiral blades 22 are in contact with the inner wall of the cooking pipe 1, and when the cooking pipe 1 is a coated pot, the spiral blades 22 are preferably at a distance of 1mm-5mm from the pot wall.

[0038] Compared with the existing push rod with an integrated structure, the food pushing device of the present invention adopts multiple independent pushers 2 arranged in sequence from the head end to the tail end of the cooking pipe 1 to form a food pushing chain, and the rotation directions of the rotating drums 21 on two adjacent pushers 2 are opposite, so that the food can be alternately stir-fried up and down during the process of being pushed from the head end to the tail end of the cooking pipe 1, so that the food can be stir-fried more evenly. At the same time, the rotation speed of the two adjacent rotating drums 21 can also be intelligently controlled according to the specific cooking process requirements, which can better meet the requirements of intelligent cooking and further improve the quality of cooked dishes.

[0039] The food pushing device is preferably of the following structures. In each structure, the structure of the pusher 2 is the same or similar, and the main difference lies in the different structures of the positioning component and the rotating drive device. The positioning component and the rotating drive device in each food pushing device are described in detail below in conjunction with specific embodiments:

[0040] 1. The first structure of the food pushing device

[0041] like Figure 3-4 As shown, the rotation driving device in this structure uses a driving main shaft combined with different gear transmission mechanisms arranged in two adjacent rotating drums to realize the reverse rotation of the adjacent rotating drums. The specific structure is as follows:

[0042] 1. Positioning components

[0043] like Figure 3 As shown, the positioning component is an end cover 31 a arranged on the end surface of the drum 21 and at least one positioning rod 32 a for fixing the end cover 31 a to the shell of the cooking pipe 1 .

[0044] 1) End cap 31a

[0045] The end cap 31a is disc-shaped and connected to the drum 21 via a bearing (the bearing can be directly installed by copper rod and manual hammering). Preferably, the end cap 31a is provided on both end surfaces of the drum 21. The drum is supported by providing the end caps 31a on both end surfaces of the drum 21, which has a simple structure and is easy to assemble.

[0046] 2) Positioning rod 32a

[0047] The positioning rod 32a passes through all the end covers 31a in sequence and is fixedly connected to the end covers 31a. The two ends of the positioning rod 32a are fixedly connected to the two end surfaces of the cooking pipe 1, so that the end covers 31a and the cooking pipe 1 are relatively fixed. All the end covers 31a are placed in a fixed position in the cooking pipe 1 through the positioning rod 32a to support the rotation of the drum 21. Preferably, in the present invention, the number of the positioning rods 32a is two.

[0048] The positioning rod 32a fixes and supports the end cover 31a inside the cooking pipe 1 to install the rotating drum 21, and at the same time facilitates the positioning and installation of the rotating drive device, which has the advantages of simple structure and convenient assembly.

[0049] 2. Rotation drive device

[0050] like Figure 2-3 The rotary drive device includes a driving spindle 41a, a motor 42a, a forward gear transmission mechanism and a reverse gear transmission mechanism.

[0051] 1) Driving spindle 41a and motor 42a

[0052] The driving main shaft 41a passes through all the end covers 31a, and one end thereof passes through one end surface of the cooking pipe 1 and is connected to the output end of the motor 42a installed on the end surface, and the other end is mounted on the other end surface of the cooking pipe 1 through a bearing. The rotation direction and rotation speed of the driving main shaft 41a are controlled by the motor 42a. The axis of the driving main shaft 41a overlaps with the axis of the drum 21. Under the action of the motor 42a and the driving main shaft 41a, the drum 21 rotates around the driving main shaft 41a as the axis.

[0053] In the present invention, the driving main shaft 41a and the end cover 31a are preferably connected by a bearing.

[0054] 2) Forward gear transmission mechanism and reverse gear transmission mechanism

[0055] The forward gear transmission mechanism and the reverse gear transmission mechanism are used to transmit the power of the driving main shaft 41 a to the rotating drum 21 so that the rotation directions of two adjacent rotating drums 21 are opposite.

[0056] For the convenience of description, in the cooking pipe 1, with the end face facing the head end of the cooking pipe 1 as a reference, when the driving main shaft 41a rotates counterclockwise, the rotating drum rotating clockwise is called the forward rotating drum 211a, and the rotating drum rotating counterclockwise is called the reverse rotating drum 212a. The forward gear transmission mechanism is arranged in the forward rotating drum 211a, and the reverse gear transmission mechanism is arranged in the reverse rotating drum 212a.

[0057] By arranging a forward gear transmission mechanism and a reverse gear transmission mechanism on a driving main shaft 41a to realize reverse rotation between adjacent rotating drums, the structure is simple, the stability is high, and the maintenance cost is low. At the same time, using a driving main shaft 41a can increase the shaft diameter of the driving main shaft 41a, thereby improving the strength of the driving main shaft 41a.

[0058] Specifically, the forward gear transmission mechanism is composed of a first gear 43a and a second gear 44a. The first gear 43a is sleeved on the driving main shaft 41a and fixedly connected to the driving main shaft 41a. The second gear 44a is externally meshed with the first gear 43a and is internally meshed with the forward gear ring 45a provided on the inner wall of the forward rotating cylinder 211a. The second gear 44a can be fixedly installed on the corresponding end cover 31a (it can be installed on one end cover 31a or mounted between the two end covers 31a) through a gear shaft. The gear shaft and the second gear 44a are connected through a bearing. The positioning rod 32a can also be set at a position opposite to the second gear 44a, and the second gear 44a is sleeved on the positioning rod 32a through a bearing.

[0059] The reverse gear transmission mechanism is composed of a third gear 46a, a fourth gear 47a and a fifth gear 48a meshing with each other. The third gear 46a is sleeved on the driving main shaft 41a and fixedly connected to the driving main shaft 41a. The fourth gear 47a is between the third gear 46a and the fifth gear 48a, and is externally meshed with the third gear 46a and the fifth gear 48a respectively. At the same time, the fifth gear 48a is internally meshed with a reverse gear ring 49a arranged on the inner wall of the reverse rotating drum. The fourth gear 47a and the fifth gear 48a are respectively installed on the corresponding end cover 31a through the gear shaft 471a, and the fourth gear 47a and the fifth gear 48a are connected to the corresponding gear shaft 471a through bearings.

[0060] The third gear 46a, the fourth gear 47a and the fifth gear 48a are all cylindrical gears. At this time, the relationship between the number of teeth of each gear corresponding to the ratio of the speed of the forward rotating drum 211a and the reverse rotating drum 211a can be deduced from the following:

[0061] Set the angular velocity ω of the driving spindle 41a 10 , speed V 10 ;

[0062] Angular velocity ω of the forward rotating drum 211a 正 , speed V 正 , the number of teeth Z of the positive rotation ring gear 45a 正 ;

[0063] Angular velocity ω1 of the first gear 43a = angular velocity ω of the drive spindle 41a 10 , speed V1 = speed V of the driving spindle 41a 10 , number of teeth Z1;

[0064] Angular velocity ω2, rotation speed V2, number of teeth Z2 of the second gear 44a;

[0065] Angular velocity ω of the reverse rotating drum 212a 反 , speed V 反 , the number of teeth Z of the counter gear ring 49a 反 ;

[0066] Angular velocity ω3 of the third gear 46a = angular velocity ω of the drive spindle 41a 10 , speed V3 = speed V of the driving spindle 41a 10 = speed V1, number of teeth Z3;

[0067] The angular velocity ω4, rotation speed V4, and number of teeth Z4 of the fourth gear 47a;

[0068] The angular velocity ω5, rotation speed V5, and number of teeth Z5 of the fifth gear 48a;

[0069] The transmission ratio between the first gear 43a and the forward rotating drum 211a is: ω1 / ω 正 =V1 / V 正 =Z 正 / Z1; the speed of the forward rotating drum 211a is: V 正 =(V1*Z1) / Z 正 ;

[0070] The transmission ratio between the third gear 46a and the reverse rotating drum 212a is derived from the following three steps:

[0071] Step 1: The transmission ratio of the third gear 46a and the fourth gear 47a: ω3 / ω4=V3 / V4=Z4 / Z3;

[0072] Then V4=(V3*Z3) / Z4;

[0073] Step 2: The transmission ratio of the fourth gear 47a and the fifth gear 48a: ω4 / ω5=V4 / V5=Z5 / Z4;

[0074] Then V5=(V3*Z3 / Z4)*(Z4 / Z5)=(V3*Z3) / Z5;

[0075] Step 3: Transmission ratio of the fifth gear 48a and the reverse rotating drum 212a: ω5 / ω 反 =V5 / V 反 =Z 反 / Z5;

[0076] V 反 =(V5*Z5) / Z 反 ={[(V3*Z3) / Z5]*Z5} / Z 反 =(V3*Z3) / Z 反 ;

[0077] Finally, the relationship between the number of teeth of each gear corresponding to the speed ratio of the forward rotating drum 211a and the reverse rotating drum 212a is obtained as follows: 正 / V 反 =(Z1*Z 反 ) / (Z 正 *Z3).

[0078] It can be deduced from the above formula that the speed ratio between the forward rotating drum 211a and the reverse rotating drum 212a can be controlled by setting the number of teeth of the forward rotating ring gear 45a, the reverse rotating ring gear 49a, the first gear 43a and the third gear 46a.

[0079] The structure adopts cylindrical gears entirely, and has a simple structure, high stability and high control accuracy.

[0080] Preferably, Figure 4 As shown, the third gear, the fourth gear and the fifth gear may also be of the following structure:

[0081] The third gear 46b is a cylindrical gear, the fourth gear 47b and the fifth gear 48b are gears with shaft teeth and disc teeth (the shaft teeth and disc teeth are preferably an integrated structure), the third gear 46b is externally meshed with the shaft teeth 471b of the fourth gear 47b, the disc teeth 472b of the fourth gear 47b are externally meshed with the shaft teeth 481b of the fifth gear 48b, and the disc teeth 482b of the fifth gear 48b are internally meshed with the reverse gear ring 49b. At this time, the relationship between the number of teeth of each gear corresponding to the speed ratio of the forward rotating drum 211a and the reverse rotating drum 212b can be deduced from the following:

[0082] Set the angular velocity ω of the reverse rotating drum 212b 反 , , speed V 反 , , the number of teeth Z of the counter gear ring 49b 反 , ;

[0083] Angular velocity ω3 of the third gear 46b , = angular velocity ω of the driving spindle 41a 10, speed V3 , = Speed ​​V of the driving spindle 41a 10 =Speed ​​V1, number of teeth Z3 , ;

[0084] The angular velocity ω of the shaft tooth 471b of the fourth gear 47b 41 , speed V 41 , number of teeth Z 41 ;

[0085] The angular velocity ω of the disc tooth 472b of the fourth gear 47b 42 , speed V 42 , number of teeth Z 42 ;

[0086] Angular velocity ω of the shaft tooth 481b of the fifth gear 48b 51 , speed V 51 , number of teeth Z 51 ;

[0087] Angular velocity ω of the disc tooth 482b of the fifth gear 48b 52 , speed V 52 , number of teeth Z 52 ;

[0088] The transmission ratio between the third gear 46b and the reverse rotating drum 212b in the structure is deduced by the following three steps:

[0089] Step 1: Transmission ratio of the third gear 46b and the shaft tooth 471b of the fourth gear 47b: ω3 , / ω 41 =V3 , / V 41 =Z 41 / Z3 , , then V 41 =(V3 , *Z3 , ) / Z 41 =V 42 ;

[0090] Step 2: The transmission ratio between the disc teeth 472b of the fourth gear 47b and the shaft teeth 481b of the fifth gear 48b: ω 42 / ω 51 =V 42 / V 51 =Z 51 / Z 42 , then V 51 =(V 42 *Z 42 ) / Z 51 ={

(V3 , *Z3 , ) / Z 41

[0091] Step 3: The transmission ratio between the disc teeth 482b of the fifth gear 48b and the reverse rotating drum 212b: ω 52 / ω 反 , =V 52 / V 反 , =Z 反 , / Z 52 , then V 反 , =(V 52 *Z 52 ) / Z 反 , ={[(V1*Z3 , *Z 42 ) / (Z 41 *Z 51 )】*Z 52} / Z 反 , =(V1*Z3 , *Z 42 *Z 52 ) / (Z 41 *Z 51 *Z 反 , )

[0092] It is known from the above that the transmission ratio between the first gear 43a and the forward rotating drum 211a is: 正 =(V1*Z1) / Z 正 ;

[0093] Then, the relationship between the number of teeth of each gear corresponding to the ratio of the speed of the forward rotating drum 211a and the reverse rotating drum 212b in this structure can be deduced as follows: 正 / V 反 , =

(V1*Z1) / Z 正

(V1*Z3 , *Z 42 *Z 52 ) / (Z 41 *Z51 *Z 反 , )

[0094] The reverse gear transmission mechanism in the structure adopts gears with shaft teeth and disc teeth, which has higher space utilization rate, simple structure, high stability and high control accuracy.

[0095] 2. The second structure of the food pushing device

[0096] like Figure 5-10 As shown, the rotation driving device in the structure adopts a transmission gear sleeved on the driving shaft 41c to mesh with the inner gear ring on the inner wall of the rotating drum 21c at the corresponding position to realize direct transmission. In this structure, the number of driving shafts 41c can be set to be consistent with the number of rotating drums 21c, so as to realize the individual control of the speed and rotation direction of each rotating drum 21c. It is also possible to use two driving shafts 41c to drive all the forward rotating drums 211c and all the reverse rotating drums 212c (in the cooking pipe 1, the end surface facing the head end of the cooking pipe 1 is used as a reference, the rotating drum rotating clockwise is called the forward rotating drum, and the rotating drum rotating counterclockwise is called the reverse rotating drum) to realize the rotation direction and speed control of the forward rotating drum 211c and the reverse rotating drum 212c. The specific scheme is as follows:

[0097] 1. Positioning components

[0098] like Figure 5-6 As shown, the positioning component is a cylindrical support column 31c, and at least two long grooves 311c are arranged along the circumferential direction on the support column 31c and pass through the head and tail of the support column 31c and are used to install the drive shaft 41c. The cross-section of the long groove 311c along the vertical axis direction of the support column 31c is arc-shaped, preferably semicircular, the two ends of the support column 31c are fixedly connected to the two end surfaces of the cooking pipe 1, and the support column 31c and the cooking pipe 1 are coaxially arranged, and the number of the long grooves 311c is the same as the number of the drive shaft 41c.

[0099] By configuring the positioning component as a support column 31c connected to the central axis of the cooking pipe 1, the support strength is high and the overall assembly is convenient.

[0100] All the rotating drums 21c are arranged in sequence and sleeved on the support column 31c through bearings so that the rotating drum 21c can rotate relative to the support column 31c. Preferably, each rotating drum 21c is connected to the support column 31c through two bearings. The provision of two bearings can ensure the stability of the rotating drum 21c during the rotation around the axis and avoid eccentric movement.

[0101] 2. Rotation drive device

[0102] In this structure, the rotary drive device has the following two structures:

[0103] 1) Solution of multiple drive shafts 41c:

[0104] like Figure 5-7 As shown, the rotation driving device includes at least two driving shafts 41c, driving motors correspondingly connected to the driving shafts 41c, and the transmission gears.

[0105] In this structure, the number of the driving shafts 41c is consistent with the number of the rotating drums 21c, all the driving shafts 41c are parallel to the central axis of the rotating drum 21c, and each driving shaft 41c independently controls the rotation of a rotating drum 21c.

[0106] like Figure 8 As shown, the driving motor is preferably a DC reduction motor 42c, which is fixedly connected to the outer surface of the head end of the cooking pipe 1 near the outer periphery in a horizontal manner, and its output shaft 421c finally extends outward in a manner perpendicular to the outer surface through a turbine worm structure (the direction perpendicular to the end face of the cooking pipe 1 pointing to the outside of the cooking pipe 1 is the outside), one end of the driving shaft 41c is placed outside the outer end face and parallel to the output shaft 421c (for the convenience of description, the end placed outside the cooking pipe 1 is called the head end 411c of the driving shaft, and the end placed inside the cooking pipe 1 is called the tail end 412c of the driving shaft, the same below), the output shaft 421c and the head end 411c of the driving shaft 41c are connected by a belt 44c, and the driving shaft 41c is connected to the head end of the cooking pipe 1 by a bearing. Driven by the DC reduction motor 42c, the driving shaft 41c can rotate relative to the cooking pipe 1.

[0107] The tail end 412c of the driving shaft 41c enters the cooking pipe 1 and is placed in the corresponding long groove 311c and is rotatably supported in the long groove 311c by a bearing. Preferably, the tail end 412c of the driving shaft 41c is located in the corresponding driven drum 21c.

[0108] By horizontally arranging the DC reduction motor 42c on the end face of the cooking pipe 1, the end face position of the cooking pipe 1 is fully utilized to avoid directly connecting the output shaft 421c of the DC reduction motor 42c with the drive shaft 41c, which would cause the overall length of the intelligent cooking machine to be too long.

[0109] To facilitate quick installation of the bearing, Figure 7-9 As shown, a stopper 45c in the shape of a long rod and made of aluminum profile is provided in the long groove 311c. The end surface of the stopper 45c is divided into two parts, one part is used to fix the outer ring of the bearing 454c, and the other part is a hollow channel for the driving shaft 41c to pass through. The inner ring of the bearing 454c is sleeved on the driving shaft 41c. The number of bearings 454c can be one or two. When there are two bearings 454c, they are respectively installed on the two end surfaces of the stopper 45c. The peripheral wall of the member 45c is surrounded by a first arc surface 452c and a second arc surface 453c. The first arc surface 452c is adapted to the arc surface of the long groove 311c. The curvature of the second arc surface 453c is similar to the curvature of the outer peripheral wall of the support column 31c. Thin slide rails 451c extending along the length direction of the limiting member 45c are provided on the sides where the two arc surfaces meet, and correspondingly, slide grooves 312c are provided on both sides of the long groove 311c to allow the thin slide rails 451c to be inserted therein.

[0110] Assembly relationship: first install the bearing 454c on the limiting member 45c to form an assembly, and then insert the limiting member 45c into the slide groove 312c by means of a thin slide rail 451c to carry the bearing 454c and place it in the position corresponding to the rotating drum 21c in the long groove 311c, the first arc 452c surface fits with the inner wall of the long groove 311c, and is fixedly connected therebetween, and the drive shaft 41c passes through the through hole of the inner ring of the bearing 454c and fits tightly with it.

[0111] The limiting member 45c can be assembled with the bearing 454c into a component, and then quickly inserted into the long groove 311c in the form of a slide groove 312c to achieve the positioning and installation of the bearing 454c in the long groove 311c, thereby achieving the circumferential limitation of the tail end 412c of the drive shaft 41c and supporting the drive shaft 41c in the long groove 311c, which simplifies the assembly and facilitates modular production.

[0112] In this structure, the transmission gear is a disc gear 43c, which is sleeved on the driving shaft 41c. Preferably, the disc gear 43c is arranged at a position close to the limit member 45c, and the inner ring gear is an annular ring gear 213c, which is arranged on the inner wall of the rotating drum 21c corresponding to the disc gear 43c. The driving shaft 41c rotates synchronously with the disc gear 43c to drive the rotating drum 21c to rotate around the axis of the rotating drum 21c.

[0113] The structure adopts a one-to-one correspondence between the DC reduction motor 42c, the drive shaft 41c and the rotating drum 21c, and the speed and rotation direction of each rotating drum 21c can be controlled individually, so that the level of intelligent cooking is higher.

[0114] Preferably, in this structure, in order to reduce the process requirements for the support column 31c and save costs, the support column 31c is made of aluminum profiles, and the bearing connecting the rotating drum 21c and the support column 31c is positioned and installed on the support column 31c through a transition connector. The advantage of the transition connector is that there is no need to open a bearing installation position on the support column 31c, thereby avoiding increasing the processing difficulty of the support column 31c. Moreover, since the precision requirements for bearing installation are relatively high, the support column 31c is a long strip and an integrally molded structure, which cannot meet the precision requirements for bearing installation, or the material of the support column 31c needs to be changed, which increases costs.

[0115] Preferably, the transition connector has the following two structures:

[0116] a. Figure 5 and Figure 7 As shown, the transition connector is a rigid sleeve 46c, the length of which is less than the length of the rotating cylinder 21c and is close to the length of the stopper 45c, the rigid sleeve 46c is sleeved on the support column 31c and wraps the stopper 45c therein, and is fixed to the stopper 45c by screws to be fixed to the support column 31c, the outer walls of both ends of the rigid sleeve 46c are provided with bearing clamping positions, the inner ring of the bearing is sleeved in the bearing clamping position and is positioned and connected between the rigid sleeve 46c by clamping (the clamping method can be a retaining spring, etc.), the outer ring of the bearing is tightly fitted with the inner wall of the rotating cylinder, and the rigid sleeve 46c is located in the middle of the rotating cylinder. The annular gear ring 213c is arranged on the inner wall of the rotating cylinder 21c outside the rigid sleeve 46c.

[0117] By setting a rigid sleeve 46c, two bearings are pre-installed on both ends of the rigid sleeve to form an assembly, and then the entire assembly is fixed to the support column 31c. This structure is easy to assemble, helps to improve production efficiency and save production costs.

[0118] b. The transition connector is two independent cylindrical sleeves (not shown in the figure), which are respectively arranged near the two ends of the drum. The bearing is installed on the sleeve in the same way as the rigid sleeve. Similarly, the sleeve is also made of a rigid material with high strength.

[0119] Two bearings are installed near the two ends of the drum through two independent rings to support the two ends of the drum, and a position for installing the disc gear 43c and the inner teeth is reserved in the middle to form a stable structure with central drive and two-end support, so that the transmission force on the drum is more balanced and the movement of the drum is smoother during rotation.

[0120] Furthermore, in order to prevent the food from getting stuck in the gap between the rotating drum and the support column 31c when the rotating drum is pushing the food, sealing rings are provided on the support column 31c at positions corresponding to the two end surfaces of the rotating drum to seal the support column 31c and the rotating drum.

[0121] By setting the positioning component as a support column 31c to install and support the drum 21c and the rotary drive device, the support strength is high, the assembly is simple, and modular production and assembly are convenient.

[0122] In this structure, the positioning component may also be an end cover provided on the end surface of the rotating drum 21c, and the end cover is connected to the rotating drum 21c via a bearing. Preferably, end covers are provided on both side end surfaces of the rotating drum 21c.

[0123] When the positioning component is an end cover, the installation method of the driving shaft 41c, the cooking pipe 1 and the driving motor 42c is the same as the above structure, which will not be repeated here.

[0124] The at least two drive shafts 41c are staggered and parallel to the central axis of the rotating drum 21c, and all pass through the end cover to limit the position of the end cover in the circumferential direction. At the same time, all the drive shafts 41c are connected to the end cover through bearings, and the drive shaft 41c and the inner ring of the bearing are interference fit to limit the position of the end cover in the axial direction, thereby supporting the rotating drum 21c in a fixed position in the axial direction in the cooking pipe 1.

[0125] The disc gear 43c is arranged at any position on the driving shaft 41c located in the drum and rotates synchronously with the driving shaft. The disc gear 43c is externally meshed with the annular gear ring 213c arranged on the inner wall of the drum 21c.

[0126] The support of the rotating drum 21c is achieved by arranging end covers on both end surfaces of the rotating drum 21c, and the rotary drive device can be supported and installed on the end covers at the same time, which has a simple structure and is easy to assemble.

[0127] 2) Two drive shafts:

[0128] The transmission principle of this structure is the same as that of the above structure, and the connection and installation method of the drive shaft and the motor are the same as those of the above structure, which will not be repeated here.

[0129] like Fig.10 As shown, the difference lies in that there are two drive shafts, namely a forward drive shaft 413c and a reverse drive shaft. Preferably, the forward drive shaft 413c and the reverse drive shaft are symmetrical with respect to the central axis of the drum. The forward drive shaft 413c controls the rotation of all forward drums 211c (in the cooking pipe 1, the drum rotating clockwise is called the forward drum 211c, and the drum rotating counterclockwise is called the reverse drum, with the end face facing the head end of the cooking pipe 1 as a reference), and the reverse drive shaft controls the rotation of all reverse drums.

[0130] Correspondingly, there are two long grooves 311c on the support column 31c, and the forward driving shaft 413c and the reverse driving shaft both pass through the forward rotating drum 211c and the reverse rotating drum arranged crosswise from the head end to the tail end of the cooking pipe 1 in sequence, so that the tail end 4131c of the forward driving shaft 413c is placed in the last forward rotating drum 211c, and the tail end of the reverse driving shaft is placed in the last reverse rotating drum.

[0131] In this structure, the transmission gear is divided into a forward drive gear 4132c (hereinafter the forward drive gear is referred to as the forward drive gear) and a reverse drive gear (hereinafter the reverse drive gear is referred to as the reverse drive gear), and the inner ring gear is divided into a forward ring gear 2111c and a reverse ring gear, and the forward drive shaft 413c corresponding to the forward rotating cylinder 211c is provided with the forward drive gear 4132c meshing with the forward ring gear 2111c on the inner wall of the forward rotating cylinder 211c; and the reverse drive shaft corresponding to the reverse rotating cylinder is provided with a reverse drive gear meshing with the reverse ring gear on the inner wall of the reverse rotating cylinder.

[0132] Similarly, in order to ensure the tightness of the meshing between the forward gear ring 2111c and the forward drive gear 4132c (or the meshing between the reverse gear ring and the reverse drive gear) during the transmission process between the drive shaft and the rotating drum, the limiting member 45c in the above-mentioned structure is used to install bearings near the forward drive gear 4132c and the reverse drive gear to provide limited support for the forward drive shaft 413c and the reverse drive shaft, so as to limit the forward drive shaft 413c and the reverse drive shaft in the long groove 311c, so as to avoid gear transmission dislocation during the transmission process, resulting in the inability to drive the rotating drum to rotate.

[0133] Compared with the solution with multiple drive shafts, this structure can realize the reverse rotation of two adjacent drums on all pushers in the cooking pipe 1 through two drive shafts, which has a simple structure and saves costs. At the same time, the fewer the number of drive shafts, the larger the shaft diameter of the drive shaft can be in the same installation space, so that the strength of the drive shaft is higher.

[0134] 3. The third structure of the food pushing device

[0135] The structure is that each drum is provided with a rotation drive device, so that the rotation drive device directly drives the drum to rotate, and the rotation direction and speed of each drum can be controlled individually. The specific structure is as follows:

[0136] 1. Positioning components

[0137] like Figure 11-13As shown, the positioning component includes a fixing member 31d and at least two positioning beams 32d. The fixing member 31d is cylindrical in shape, with a length less than the length of the drum 21d and a diameter less than the inner diameter of the drum 21d. A mounting position 311d for mounting a high-temperature resistant motor 41d of a rotating drive device is provided near the outer edge of the circumference of the fixing member 31d. Hollow channels 312d parallel to the central axis of the fixing member 31d and used for mounting the positioning beams 32d are evenly distributed in the circumferential direction of the fixing member 31d.

[0138] Preferably, the fixing member 31d is arranged in the middle of the rotating drum 21d and is connected to the rotating drum 21d through the supporting bearing 22d, and steps are arranged at both ends of the fixing member 31d, and the inner ring of the supporting bearing 22d is sleeved on the slope of the step with a tight fit therebetween. Correspondingly, an annular first step 211d and a second step 212d are arranged on the inner wall of the rotating drum 21d, and the first step 211d is arranged near one end surface of the rotating drum 21d, and the height of the second step 212d does not exceed half of the total height of the rotating drum 21d (taking the one end surface as the bottom surface and the other end surface as the top surface, the height of the step refers to the vertical distance from the step surface to the bottom surface, and the height of the rotating drum refers to the distance from the top surface to the bottom surface of the rotating drum). vertical distance), the fixing member 31d fixed with the support bearing 22d is pressed into the rotating drum 21d from the other end of the rotating drum 21d in a coaxial manner with the rotating drum 21d, so that the side surface of the outer ring of the support bearing 22d at one end of the fixing member 31d is pressed against the table surface of the second step 212d, and then abutted against the outer ring side wall of the support bearing 22d at the other end through an annular pressing member 24d, the pressing member 24d is fixedly connected to the rotating drum 21d to limit the fixing member 31d to a fixed position in the middle of the rotating drum 21d, the outer ring circumferential wall of the support bearing 22d is tightly fitted with the inner wall of the rotating drum 21d, and the rotating drum 21d can rotate relative to the fixing member 31d.

[0139] 2. Rotation drive device

[0140] The rotary drive device includes the high temperature resistant motor 41d, the main drive gear 42d and the driven gear ring 23d. The driven gear ring 23d is a ring structure with internal teeth, which is fixed on the table of the first step 211d. The high temperature resistant motor 41d is preferably a DC planetary reduction motor, which has the advantages of small size and large output torque. The main body of the high temperature resistant motor 41d is accommodated in the installation position 311d, and its output shaft 411d extends beyond the end surface of the fixing member 31d and Pointing to the area enclosed by the inner teeth of the driven gear ring 23d, the high temperature resistant motor 41d is provided with an output shaft 411d, one end face of which is placed outside the fixing member 31d or flush with the end face of the fixing member 31d and fixed to the end face of the fixing member 31d through a base, and the main drive gear 42d is sleeved on the end of the output shaft 411d and meshed with the driven gear ring 23d. The high temperature resistant motor 41d drives the main drive gear 42d to rotate to drive the rotating drum 21d to rotate around the axis of the rotating drum 21d.

[0141] This structure adopts one rotating drum 21d corresponding to one rotating drive device, and the speed and rotation direction of each rotating drum 21d can be controlled individually, which has a higher degree of intelligent cooking. At the same time, this structure embeds all the rotating drive devices in the corresponding rotating drum 21d, so that the distance between the driving component (high temperature resistant motor) and the driven component (rotating drum) is reduced, thereby reducing the lever arm, increasing the torque, and saving energy consumption.

[0142] Through the above structure, the fixing part 31d, the high temperature resistant motor 41d and the rotating drum 21d are assembled into a module, and then the positioning beam 32d is sequentially inserted into the hollow channel 312d to connect the modules in series to form a food pushing device. The two ends of the positioning beam 32d are fixedly connected to the two end surfaces of the cooking pipe 1 to mount the food pushing device in the cooking pipe 1.

[0143] Preferably, the number of the positioning beams 32d is three, and the three positioning beams 32d are used to fix the fixing member 31d in a tripod structure to limit its position in the circumferential direction, thereby preventing the fixing member 31d from generating rotational movement in the circumferential direction due to the resistance of the rotating drum 21d when the high-temperature resistant motor 41d drives the rotating drum 21d to rotate.

[0144] Preferably, the positioning beam 32d is a hollow structure, and the wires of the high temperature resistant motor 41d can be led out through the positioning beam 32d to the outside of the cooking pipe 1 and electrically connected to the controller of the intelligent cooking machine. Similarly, the high temperature resistant motor 41d can be cooled by blowing low-temperature gas into the positioning beam 32d to ensure the service life of the high temperature resistant motor 41d.

[0145] Furthermore, to facilitate installation, a central channel is provided at the central axis position of the fixing member 31d, a positioning screw 33d is passed through the central channel, and nuts are screwed on the positions where the positioning screw 33d passes through the two end surfaces of the cooking pipe 1 to press against the end surfaces of the cooking pipe 1 so as to fix the fixing member 31d to the cooking pipe 1. This structure uses the positioning screw 33d for fixed installation and the positioning beam 33d for positioning and routing, which is more stable in structure and more convenient to assemble.

[0146] In order to make the pushing module easier to modularize and assemble, a first connecting member 34d and a second connecting member 35d are respectively provided at both ends of the rotating drum 21d, and the first connecting member 34d and the second connecting member 35d are in a male-female connection relationship. That is, when two adjacent pushing modules are connected end to end, the second connecting member 35d of the previous pushing module and the first connecting member 34d of the subsequent pushing module are quickly connected through the male-female structure.

[0147] Specifically, the first connecting member 34d is a disc structure with a certain thickness. The first connecting member 34d is accommodated in the rotating drum 21d in a coaxial manner with the rotating drum 21d, and the outer end face of the first connecting member 34d is flush with the end face of the rotating drum 21d. An inwardly recessed cylindrical position is provided in the middle of the first connecting member 34d (the direction pointing into the rotating drum is inward), and a through hole for the positioning beam 32d or the positioning screw 33d to pass through is provided at the bottom of the cylindrical recess and at a position opposite to the hollow channel 312d and the center channel on the fixing member 31d. At least two protrusions 351d extending toward the outer end face are provided at the bottom of the cylindrical recess and offset from the through holes, and a blind hole is provided inside the protrusion 351d.

[0148] Correspondingly, the second connecting member 35d is a cylindrical structure, which is coaxially arranged with the rotating drum 21d, and part of it is placed inside the rotating drum 21d, and the other part is exposed from the rotating drum 21d and placed outside the rotating drum 21d. The outer diameter of the second connecting member 35d is slightly smaller than the diameter of the cylindrical recess. Similarly, a through hole for the positioning beam 32d or the positioning screw 33d to pass through is provided at the bottom of the second connecting member 35d and at a position opposite to the hollow channel 312d and the center channel on the fixing member 31d. At least two connecting columns 351d extend upward from the inner bottom surface of the second connecting member 35d, and the diameter of the connecting column 351d is adapted to the blind hole.

[0149] The first connecting member 34d and the second connecting member 35d are connected to the corresponding fixing member 31d through a connecting rod 36d, and a sealing ring is provided between the outer peripheral wall of the first connecting member 34d and the second connecting member 35d and the rotating drum 21d.

[0150] When two adjacent pushing modules are assembled, the second connecting member 35d of the previous pushing module is inserted into the circular recess of the first connecting member 34d of the subsequent pushing module, and at the same time, the connecting column 351d on the second connecting member 35d is inserted into the blind hole of the protruding column 341d of the first connecting member 34d for quick positioning and connection. At this time, the hollow channel 312d on the fixing member 31d is directly corresponding to the through holes on the first connecting member 34d and the second connecting member 35d, and the positioning beam 32d and the positioning screw 33d can pass through all the pushing modules in turn to fix the pushing modules on the cooking pipe 1.

[0151] The structure can be produced in a modular manner, is easy to assemble, is conducive to improving production efficiency, and the rotation direction and rotation speed of each drum can be freely set.

[0152] 4. The fourth structure of the food pushing device

[0153] The number of driving spindles in the rotary drive device in this structure is consistent with the number of drums, and one driving spindle drives one drum to rotate. This structure has the same driving principle as the second structure. The drum and the driving spindle are connected by gear transmission. The difference is that in this structure, all driving spindles are installed in a coaxial sleeve manner, which has the advantage of saving the internal space of the drum. The specific structure is as follows:

[0154] 1. Positioning components

[0155] like Figure 14-16 As shown, the positioning component is a cylindrical positioning beam 31e. Preferably, the positioning beam 31e is an aluminum profile. A mounting groove 311e is provided on the positioning beam 31e along the axial direction and used to install the rotating drive device. Both ends of the positioning beam 31e are fixedly connected to the two end surfaces of the cooking pipe 1, and the positioning beam 31e is coaxially arranged with the cooking pipe 1.

[0156] 2. Rotation drive device

[0157] like Fig.15 As shown, the rotary drive device is composed of a plurality of sleeve shafts 41e with increasing diameters, coaxially arranged and partially overlapping, and a drive shaft motor 42e for driving the sleeve shafts 41e to rotate. The length of the sleeve shaft 41e with a smaller diameter is greater than the length of the sleeve shaft 41e with a larger diameter. Among two adjacent sleeve shafts 41e, the sleeve shaft 41e with a larger diameter is all sleeved on the sleeve shaft 41e with a smaller diameter. One end of all the sleeve shafts 41e is positioned and installed in the cooking pipe 1 through the positioning beam 31e, and the other end is placed outside the cooking pipe 1 and connected to the corresponding drive shaft motor 42e.

[0158] Specifically, the ends of all sleeve shafts 41e placed outside the cooking pipe 1 (hereinafter, the end of the sleeve shaft placed outside the cooking pipe is referred to as the head end, and the end placed inside the cooking pipe is referred to as the tail end) are distributed in steps, a transmission wheel 46e is sleeved on the head end of each sleeve shaft 41e, and a bearing for rotationally supporting the sleeve shaft 41e is sleeved at a position near the transmission wheel 46e, the outer ring of the bearing is directly or indirectly fixed to the end face of the cooking pipe 1, and the same number of drive shaft motors 42e as the number of the sleeve shafts 41e are staggered along the circumferential direction of the sleeve shaft 41e. The drive shaft motor 42e is fixedly installed on the outer end face of the cooking pipe 1 through a mounting frame in a manner such that the height of its output shaft 421e is at a position corresponding to the position of the transmission wheel 46e on the sleeve shaft 41e driven by it, and the output shaft 421e of the drive shaft motor 42e is connected to the transmission wheel 46e through a belt 47e to drive the sleeve shaft 41e to rotate.

[0159] Each sleeve shaft 41e placed in the cooking pipe 1 is installed in the installation groove 311e, and the end of each sleeve shaft 41e is placed in the corresponding driven drum 21e. Specifically, the ends of the sleeve shafts 41e with diameters from large to small correspond to the drums 21e arranged from the head end to the tail end of the cooking pipe 1, that is, the end of the sleeve shaft 41e with the largest diameter is located in the first drum 21e arranged from the head end to the tail end in the cooking pipe 1, and the end of the sleeve shaft 41e with the smallest diameter is located in the last drum 21e arranged from the head end to the tail end in the cooking pipe 1.

[0160] All the rotating drums 21e in the cooking pipe 1 have the same outer diameter, and the spiral blades extend from one end of the rotating drum 21e to the other end. To facilitate production and processing, the structure of the rotating drum 21e is a cylindrical structure, and the rotating drum 21e can be rotatably positioned in the cooking pipe 1 through the positioning beam 31e. The positioning beam 31e and the rotating drum 21e use the same transition connector as in the second structure to install the bearing to achieve the rotational connection between the positioning beam 31e and the rotating drum 21e. The installation method and function are the same, and will not be repeated here.

[0161] like Figure 15-16 As shown, for the convenience of assembly, the sleeve shaft 41e is positioned and supported by the kit 45e in the mounting groove 311e. Specifically, the outer layer of the kit 45e is a cylindrical structure, and an arched tunnel 451e is provided on the inner wall of the kit 45e along the axial direction of the kit 45e. The cross-sectional shape of the area enclosed by the inner wall of the kit 45e and the upper surface of the arched tunnel 451e is adapted to the cross-sectional shape of the positioning beam 31e, and the diameter of the kit 45e is slightly larger than the diameter of the positioning beam 31e, so that the kit 45e can be placed on the positioning beam 31e in a manner that the arched tunnel 451e is inserted into the mounting groove 311e.

[0162] Furthermore, a hollow cylinder 452e for fixing and installing a bearing 44e is provided in the arched tunnel 451e. The bearing 44e is first fixed in the hollow cylinder 452e, and then the sleeve 45e is sleeved on the positioning beam 31e at a position corresponding to the tail end of the corresponding sleeve shaft 41e, so that the tail end of the sleeve shaft 41e is inserted into the inner ring of the bearing 44e to rotatably support the sleeve shaft 41e in the cooking pipe 1. By providing the sleeve 45e, the positioning and installation between the bearing 44e and the sleeve shaft 41e can be facilitated.

[0163] All the rotating drums 21e are arranged in sequence from the head end to the tail end of the positioning beam 31e and are rotatably connected to the positioning beam 31e through bearings. A driving gear 43e is sleeved on the sleeve shaft 41e located in the rotating drum 21e. Correspondingly, a passive gear ring 23e meshing with the driving gear 43e is provided on the inner wall of the rotating drum 21e. Preferably, the driving gear 43e is arranged near the bearing 44e supporting the corresponding sleeve shaft 41e, and the transmission point is set near the supporting point, which is more conducive to stability during the transmission process.

[0164] In this structure, the driving main shaft is set as multiple sleeve shafts 41e in a stepped shape, so that the driving main shafts are coaxially sleeved, which reduces the volume occupied by the driving main shaft in the rotating drum, thereby reducing the volume of the entire pusher, so that the internal volume of the cooking pipe 1 of the same size becomes larger.
