[0056] Specifically, the weighing device 5 includes a heating plate 51 and a weighing device 52; the dish placement station is set on the heating plate 51, and the serving bowl 2 is placed on the heating plate 51; the heating plate 51 is placed at the weighing detection station of the weighing device 52, and the weighing device 52 is set in the weighing placement slot 10, for weighing the weight of the dishes in the serving bowl 2.

[0057] The heating plate 51 is used to heat the serving bowl 2 so that the serving bowl 2 can be maintained at a suitable temperature to improve the consumption experience of customers.

[0058] The weighing device 52 can refer to the existing smart restaurant weighing device, which can weigh the weight of the dishes in real time. According to the weight loss of the dishes and the unit price per gram of the dishes, the price required by the customer can be calculated, and then the amount can be deducted from the customer's electronic account in conjunction with the wireless radio frequency identification system and the electronic consumption system.

[0059] Specifically, the weighing device 5 further includes a support platform 53 and a translation module 54, and the support platform 53 is placed in the weighing placement slot 10;

[0060] The translation module 54 includes a translation module housing 541, a weighing drive member 542, a translation screw 543, a translation sliding nut 544, a moving guide rail 545 and a moving plate 546;

[0061] The translation module housing 541 is arranged on the support platform 53; a translation accommodating chamber 540 is arranged in the translation module housing 541, and the translation screw 543 is located in the translation accommodating chamber 540; the weighing drive member 542 is arranged at one end of the translation module housing 541; one end of the translation screw 543 is transmission-connected with the driving end of the weighing drive member 542, and the other end of the translation screw 543 is rotationally assembled on the translation module housing 541; the translation sliding nut 544 is threadedly assembled with the translation screw 543; the moving plate 546 is connected with the translation sliding nut 544, and the weighing device 52 is placed on the moving plate 546;

[0062] The translation sliding nut 544 is provided with a moving guide 547, and the moving guide rail 545 is provided in the translation accommodating cavity 540, and the moving guide rail 545 and the moving guide 547 are slidably assembled;

[0063] The weighing drive member 542 drives the translation screw 543 to rotate about its own axis, so that the translation sliding nut 544 moves along the axis of the translation screw 543 to drive the weighing device 5 to approach or move away from the outer edge of the annular bar 1.

[0064] The support platform 53 is used to support the weighing device 52 and the translation module 54. The transmission principle of the translation screw 543 and the translation sliding nut 544 can refer to the ball screw, which converts the rotational motion into linear motion. The spiral groove on the translation screw 543 guides the translation sliding nut 544 to move along the axial direction. Due to the restrictions of the moving guide 547 and the moving guide rail 545, the translation sliding nut 544 moves along the screw, thereby driving the serving bowl 2 and the weighing device 5 to approach or move away from the transfer device 3.

[0065] The translation module 54 moves the weighing device 5 closer to the transfer device 3 so that the transfer device 3 can transfer the serving bowl 2 to the weighing device 5. Then, the translation module 54 moves the serving bowl 2 and the weighing device 5 away from the transfer device 3 so that the serving bowl 2 is closer to the customer so that the customer can take the food.

[0069] The baffle connecting member 416 is connected to the lifting sliding nut 415, and the baffle connecting member 416 is provided with a baffle installation station, and the baffle 42 is detachably connected to the baffle installation station.

[0070] The transmission principle of the lifting screw 414 and the lifting sliding nut 415 can refer to the ball screw, which converts rotational motion into linear motion. The spiral groove on the lifting screw 414 guides the lifting sliding nut 415 to move axially. Due to the restrictions of the limiting protrusion 417 and the sliding groove 418, the lifting sliding nut 415 moves along the lifting screw 414.

[0071] The transmission structure can transmit torque with higher efficiency, lower friction resistance, higher precision and repeatability, and can withstand larger axial and radial loads and have a longer service life.

[0072] Specifically, the lifting assembly 41 also includes a lifting guide assembly; lifting guide assemblies are respectively provided on both sides of the baffle 42; the lifting guide assembly includes a lifting guide rail 43 and a lifting guide member 44; the lifting guide rail 43 is arranged on the annular bar 1, and the lifting guide rail 43 is provided with a guide groove 430; one end of the lifting guide member 44 is connected to the baffle 42, and the other end of the lifting guide member 44 is slidably assembled in the guide groove 430.

[0073] By adopting the above structure, through the cooperation of the lifting guide rail 43 and the lifting guide member 44, it can be ensured that the baffle 42 maintains an accurate position and direction during the movement, optimizes the movement trajectory and stability, and avoids the baffle 42 from swinging during the lifting process, thereby improving the movement accuracy and efficiency of the entire system and making the lifting process of the baffle 42 smoother.

[0074] In a specific embodiment of the present invention, the lifting guide member 44 includes a guide member body 441, a guide block 442, a first fixed plate 443 and a second fixed plate 444; the first fixed plate 443 and the second fixed plate 444 are respectively vertically arranged on one side of the guide member body 441, and the first fixed plate 443 and the second fixed plate 444 cooperate to form a baffle clamping station for clamping the baffle 42; the guide block 442 is arranged on the other side of the guide member body 441, and the guide block 442 is slidably assembled in the guide groove 430.

[0075] By adopting the above structure, the purpose of clamping the baffle 42 is achieved through the cooperation of the guide body 441, the first fixed plate 443 and the second fixed plate 444, and the guide block 442 is slidably assembled with the guide groove 430, so that the lifting guide 44 can follow the movement of the baffle, thereby achieving the purpose of limiting.

[0076] Specifically, the lifting assembly 41 further includes a connecting plate 419 and a sensor assembly 410;

[0077] The connecting plate 419 is arranged between the baffle connecting piece 416 and the lifting sliding nut 415; the sensor assembly 410 includes a baffle 4101, a first in-position sensor 4102 and a second in-position sensor 4103 arranged on the same side; the baffle 4101 is arranged on the side wall of the connecting plate 419, and the first in-position sensor 4102 and the second in-position sensor 4103 are respectively arranged on the side walls of the lifting assembly housing 412;

[0078] The first in-place sensor 4102 and the second in-place sensor 4103 are electrically connected to the lifting drive 413 respectively; when the blocking piece 4101 passes through the detection end of the first in-place sensor 4102 or the second in-place sensor 4103, the first in-place sensor 4102 or the second in-place sensor 4103 controls the lifting drive 413 to stop operating.

[0079] The connecting plate 419 serves to connect the lifting sliding nut 415 and the baffle connecting piece 416, and provides an installation position for the baffle 4101. With the above structure, the sensor assembly 410 can detect whether the first in-position sensor 4102 or the second in-position sensor 4103 rises or falls to a specific position, which can improve the safety of the mechanical system, ensure that the lifting sliding nut 415, the connecting plate 419 and the baffle connecting piece 416 move within the set vertical movement range, and avoid damage to the structure caused by the movement range of the baffle 42 exceeding the limited range.

[0080] In a specific embodiment of the present invention, the first in-place sensor 4102 is located above the second in-place sensor 4103 , and the first in-place sensor 4102 and the second in-place sensor 4103 may refer to existing in-place sensors.

[0081] When the baffle 4101 passes the detection end of the first in-place sensor 4102, the first in-place sensor 4102 is triggered, and the first in-place sensor 4102 controls the lifting drive 413 to stop operating in the form of an electrical signal, thereby preventing the lifting sliding nut 415, the connecting plate 419 and the baffle connecting member 416 from continuing to move upward. Similarly, when the lifting sliding nut 415, the connecting plate 419 and the baffle connecting member 416 move downward, the baffle 4101 moves synchronously with the connecting plate 419.

[0082] When the baffle 4101 passes the detection end of the second in-place sensor 4103, the second in-place sensor 4103 is triggered, and the second in-place sensor 4103 controls the lifting drive 413 to stop operating in the form of an electrical signal to prevent the lifting sliding nut 415, the connecting plate 419 and the baffle connecting member 416 from continuing to move downward.

[0083] Specifically, the lifting drive member 413 is arranged at the bottom of the connecting seat 411, and the driving end of the lifting drive member 413 passes through the connecting seat 411. The driving end of the lifting drive member 413 and one end of the lifting screw 414 are sleeved with a transmission belt 402.

[0084] By adopting the above structure, the vertical length of the lifting component 41 can be shortened, and the lifting component 41 can be hidden in the frame of the annular bar 1, making the overall structure of the lifting baffle more beautiful and simple; avoiding direct contact between the lifting component 41 and the juice or oil of the dishes, thereby extending the service life of the lifting component 41.
