Further, the relatively slidable plates may have at least four layers, and the at least four layers of the relatively slidable plates may form at least two telescopic units 100; the at least two telescopic units 100 include a first telescopic unit and a second telescopic unit adjacent to each other, the middle plate of the first telescopic unit is formed as the upper plate of the second telescopic unit, and the lower plate of the first telescopic unit is formed as the middle plate of the second telescopic unit.
For example, when the relatively slidable plate has four layers, the four layers of relatively slidable plate are sequentially a first layer plate, a second layer plate, a third layer plate and a fourth layer plate from top to bottom, and the four layers of relatively slidable plate can form two telescopic units, namely: the first layer plate, the second layer plate and the third layer plate form a first telescopic unit, and the second layer plate, the third layer plate and the fourth layer plate form a second telescopic unit; the first layer plate is an upper plate of the first telescopic unit, the second layer plate is a middle plate of the first telescopic unit and is also an upper plate of the second telescopic unit, the third layer plate is a lower plate of the first telescopic unit and is also a middle plate of the second telescopic unit, and the fourth layer plate is a lower plate of the second telescopic unit.

In addition, a structure for taking the food may be provided on the lowermost plate of the food taking and placing device, for example, a shovel or a claw may be provided, or the food may be taken directly by the lowermost plate of the food taking and placing device.
In order to improve the mechanical efficiency of the food taking and placing device, the extending directions of the first pulling rope 101 and the second pulling rope 102 may be parallel to the sliding direction of the middle plate 120, and the sliding direction of the middle plate 120 is the extending or retracting direction of the food taking and placing device, so that the pulling directions of the first pulling rope 101 and the second pulling rope 102 on the lower plate 130 are parallel to the extending or retracting direction of the food taking and placing device, and the mechanical efficiency of the pulling force of the first pulling rope 101 or the second pulling rope 102 on the lower plate 130 when the lower plate 130 is pulled to extend or retract is relatively high.
In order to make the first pulling rope 101 pull the lower plate 130 to extend out and the second pulling rope 102 pull the lower plate 130 to retract more stably, two first pulling ropes 101 may be provided, and the two first pulling ropes 101 are symmetrically distributed on two sides of the middle plate 120; two second pulling ropes 102 are arranged at the same time, and the two second pulling ropes 102 are symmetrically distributed on two sides of the middle plate 120.
In other embodiments, two first pulling ropes 101 and one second pulling rope 102 may be provided according to actual situations, wherein the two first pulling ropes 101 may be symmetrically distributed on two sides of the middle plate 120 or asymmetrically distributed; alternatively, one first pulling rope 101 and two second pulling ropes 102 may be provided, wherein the two second pulling ropes 102 may be symmetrically distributed on both sides of the middle plate 120 or asymmetrically distributed.
In order to make the food taking and placing device of the present embodiment have a more stable posture during the use process, when there is one telescopic unit 100, the upper plate of the telescopic unit may be set as the fixing plate 210; alternatively, when there are at least two telescopic units 100, the upper plate of the telescopic unit located at the uppermost end is set as the fixed plate 210.
In concrete implementation, the upper plate of the telescopic unit 100 positioned at the uppermost end in the food taking and placing device is set as the fixed plate 210, at this time, the middle plate 220 below the fixed plate can slide forwards and extend out under the action of driving force, and drives the lower plate to extend forwards, so that the food taking and placing device finally extends into the food container 400 and takes the food 401; then, the middle plate 220 under the fixing plate can slide backwards and retract under the driving force, and drives the lower plate to retract backwards, so that the food 401 taken by the food taking and placing device can be taken out of the food container 400, and due to the existence of the fixing plate 210, the relatively slidable plate under the fixing plate 210 can be more stable and reliable in the extending and retracting processes.
Further, the food taking and placing device of the present embodiment may further include a driving member, and the driving member may be configured to drive the middle plate 220 below the fixing plate to slide.
Specifically, the driving member may include a motor 211 disposed on the fixing plate 210, a gear (not shown) disposed on an output shaft of the motor 211, and a rack 221 disposed on the middle plate 220 below the fixing plate, and the rack 221 is engaged with the gear, so that during operation of the motor 211, the gear on the output shaft of the motor 211 can be engaged with the rack 221 on the middle plate 220 below the fixing plate to drive the middle plate 220 below the fixing plate to slide.
The motor 211 may be a stepping motor, or may be another type of motor as long as the requirements of the present embodiment regarding the motor 211 can be satisfied.
One possible mounting of the drive element is: a through hole for the output shaft of the motor 211 to pass through may be formed in the fixing plate 210, the output shaft of the motor 211 may pass through the through hole in the fixing plate 210 toward the middle plate 220 below the fixing plate, then a gear may be disposed on the output shaft of the motor exposed below the fixing plate 210, and a rack 221 engaged with the gear may be disposed on the middle plate 220 below the fixing plate, and an extending direction of the rack 221 may be parallel to a sliding direction of the middle plate 220 below the fixing plate, so that the middle plate 220 below the fixing plate may slide under the driving force of the motor 211; during concrete implementation, the driving piece can be further provided with other installation modes according to actual needs and space requirements, and the details are not repeated here.
In other embodiments, the driving member may also be another device capable of driving the middle plate 220 under the fixing plate to slide, which is described herein in detail.
In order to make the middle plate 120 of the telescopic unit 100 save more labor when the first traction rope 101 provided at the front edge of the middle plate 120 is driven and the second traction rope 102 provided at the rear edge of the middle plate 120 is driven, a first pulley 121 may be provided at the front edge of the middle plate 120 and a second pulley 122 may be provided at the rear edge of the middle plate 120; the first traction rope 101 is wound around the first pulley 121, and the second traction rope 102 is wound around the second pulley 122.
In a specific implementation, when the middle plate 120 of the telescopic unit 100 slides forwards to extend under the driving force, the first pulling rope 101 is pushed by the front edge of the middle plate 120, so that the portion of the first pulling rope 101 located below the middle plate 120 gradually winds above the middle plate 120 and pulls the lower plate 130 to extend out, because the front edge of the middle plate 120 is provided with the first pulley 121, and the first pulling rope 101 winds on the first pulley 121, the portion of the first pulling rope 101 located below the middle plate 120 can be gradually transmitted to above the middle plate 120 along the first pulley 121 and pulls the lower plate 130 to extend forwards, the transmission through the first pulley 121 not only saves labor in the process that the first pulling rope 101 pulls the lower plate 130 to extend out, but also reduces the wear between the first pulling rope 101 and the middle plate 120; when the middle plate 120 of the telescopic unit 100 is slid backward to retract by the driving force, the second traction rope 102 and the second pulley 122 are the same as the first traction rope 101 and the first pulley 121, and thus, the description thereof is omitted.
In order to make the direction between two adjacent relatively slidable plates during the sliding process better, at least one guide rail 300 may be disposed between two adjacent relatively slidable plates, and the guide rail 300 may be disposed along the sliding direction of the relatively slidable plates so that the relatively slidable plates slide along the guide rail.
One possible arrangement of the guide 300 is: one guide rail 300 may include an upper guide rail portion and a lower guide rail portion that are matched with each other, the upper guide rail portion being disposed on a lower surface of a plate located at an upper layer among two adjacent relatively slidable plates, the lower guide rail portion being disposed on an upper surface of a plate located at a lower layer among the two adjacent relatively slidable plates, the upper guide rail portion and the lower guide rail portion being slidably coupled to each other to achieve relative sliding between the two adjacent relatively slidable plates.
Further, in order to make the sliding between the upper rail portion and the lower rail portion smoother, rolling members, such as balls, may be provided between the upper rail portion and the lower rail portion to reduce the frictional force between the upper rail portion and the lower rail portion.
In order to make the sliding between two adjacent plates capable of sliding relatively more stable and reliable, and the directionality is better, two guide rails 300 can be arranged between two adjacent plates capable of sliding relatively, and the two guide rails 300 can be symmetrically arranged at two sides of the plates capable of sliding relatively, so that the plates capable of sliding relatively have more accurate directionality in the sliding process, and are more stable and reliable. In other embodiments, the number of the guide rails may also be set according to actual needs, and will not be described herein.
In order to enable the food taking and placing device to be accurately stopped in a preset retraction state in the retraction process, so as to achieve the purpose of saving space, a stopping assembly can be additionally arranged in the food taking and placing device, the stopping assembly can comprise a detection structure 212 arranged on a fixing plate 210 and a stopping block 222 arranged on a middle plate 220 below the fixing plate, and when the detection structure 212 detects that the stopping block 222 returns to a preset position, a driving part stops working, so that the food taking and placing device stops retracting; the preset position is a position of the stopping block 222 when the food taking and placing device is in a preset retraction state.
In concrete implementation, after the food taking and placing device extends out and takes food, the middle plate 220 below the fixing plate slides backwards and retracts under the action of the driving force, and drives the slidable plate below the middle plate 220 below the fixing plate to retract backwards until the detection structure 212 on the fixing plate 210 detects that the stop block 222 on the middle plate 220 below the fixing plate returns to the preset position, the driving part stops driving the middle plate 220 below the fixing plate, and at this time, the food taking and placing device retracts completely.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
