DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figure 1 and 2As shown, a circulating food sample box storage device includes a shell (not shown in the figure), and a circulating conveying mechanism installed in the shell. The side of the shell is provided with an access port for depositing and removing the food sample box 4. Depositing and removing can share the same access port, or two independent access ports can be used respectively. The access port is provided with a lockable access door. The access door can be locked after being closed to prevent unauthorized persons from opening the access port to deposit or remove the food sample box 4 and tampering with the sample retention results. The circulating conveying mechanism is used to store multiple food sample boxes 4, and to transport the designated food sample box 4 to the access port of the shell, so that the user can take out the food sample box 4.

[0028] The circulating conveying mechanism includes a frame 1, a tray circulation mechanism 2 and a material transport tray 3. The frame 1 is fixed in the shell. The frame 1 includes a bottom plate and two columns. The two vertical columns are arranged at intervals from each other, and the bottom ends are fixed to the bottom plate. The tray circulation mechanism 2 is installed between the two columns of the frame 1, and is used to store the material transport tray 3 with the food sample box 4, and drive the material transport tray 3 to move in the frame 1, so that any material transport tray 3 can be moved to a position aligned with the access port of the shell. Four sample box installation positions 3-1 arranged in sequence are provided on the material transport tray 3. The sample box installation position 3-1 is a groove-shaped structure, and its shape corresponds to the shape of the outer side surface of the food sample box 4, and can provide positioning for the food sample box 4. The food sample box 4 includes a box body 4-1 and a box cover 4-2. The box cover 4-2 is plugged into the opening of the box body 4-1.

[0029] The tray circulation mechanism 2 includes a circulating transmission component 2-1, a driving component 2-2 and a tray installation component 2-3. Two circulating transmission components 2-1 are respectively installed on opposite sides of two columns in the frame 1. The two circulating transmission components 2-1 are opposite to each other and are arranged at intervals. Multiple tray installation components 2-3 are installed between the two circulating transmission components 2-1 and can circulate under the drive of the circulating transmission component 2-1. There is a position on the moving path of the tray installation component 2-3 that is aligned with the access port of the shell.

[0030] like Figure 3 and 4 As shown, the circulating transmission component 2-1 includes a first transmission belt 2-1-2 and two first transmission wheels 2-1-3. The two first transmission wheels 2-1-3 are arranged at intervals up and down, and are both rotatably connected to the frame 1. The two first transmission wheels 2-1-3 are connected by the first transmission belt 2-1-2. In this embodiment, the first transmission belt 2-1-2 adopts a synchronous belt; the first transmission wheel 2-1-3 adopts a synchronous wheel; in addition, the first transmission belt 2-1-2 can also adopt a chain, and correspondingly, the first transmission wheel 2-1-3 adopts a sprocket. On this basis, the first transmission belt 2-1-2 and the first transmission wheel 2-1-3 can also adopt other existing structures that achieve the same function.

[0031] The two circulating transmission components 2-1 are driven by the driving component 2-2 to move synchronously. The driving component 2-2 includes a motor, a driving shaft 2-2-1 and a power transmission component 2-2-2. The motor is fixed on the frame 1. The two ends of the driving shaft 2-2-1 are respectively fixed to the first transmission wheels 2-1-3 located above in the two circulating transmission components 2-1. The power transmission component 2-2-2 includes a second transmission wheel and a second transmission belt. The two second transmission wheels are respectively fixed to the driving shaft 2-2-1 and the output shaft of the motor. The two second transmission wheels are connected by the second transmission belt, thereby enabling the motor to drive the two first transmission belts 2-1-2 to move synchronously.

[0032] A plurality of tray mounting assemblies 2-3 are arranged in sequence at equal intervals along the length direction of the first transmission belt 2-1-2. The tray mounting assembly 2-3 includes a tray bracket 2-3-1 and two connecting brackets. The tray bracket 2-3-1 is installed between the two connecting brackets. The two connecting brackets are respectively connected to the two first transmission belts 2-1-2. Each connecting bracket includes two connecting rods 2-3-2 and two mounting seats 2-3-3. The two mounting seats 2-3-3 are fixed to the corresponding first transmission belts 2-1-2.

[0033] One end of the two connecting rods 2-3-2 and the two mounting seats 2-3-3 respectively form a rotation pair with a common axis that is not colinear. The other ends of the two connecting rods 2-3-2 and the top middle position of the end surface of the tray bracket 2-3-1 form a rotation pair through the same pin shaft; the pin shaft and the tray bracket 2-3-1 and the two connecting rods 2-3-2 are not fixed, or the pin shaft and the tray bracket 2-3-1 and any one of the two connecting rods 2-3-2 are fixed. The center of gravity of the tray bracket 2-3-1 is located directly below the pin shaft.

[0034] The two connecting rods 2-3-2 are both arc-shaped rods, and the opposite side edges of the two connecting rods 2-3-2 are concave edges, thereby reducing the space occupied by the two connecting rods 2-3-2, making it easier to pull out the material transport tray 3.

[0035] Since the first transmission belt 2-1-2 will be deformed (from a straight line to an arc or from an arc to a straight line) at the position where it passes through the first transmission wheel 2-1-3; if a rigid bracket is directly used to provide support for the tray bracket 2-3-1, the rigid bracket will limit the deformation of the first transmission belt 2-1-2; resulting in the first transmission belt 2-1-2 being difficult to deform freely when passing through the first transmission wheel 2-1-3, causing a large force to be generated between the rigid bracket and the first transmission belt 2-1-2, affecting the movement stability of the tray bracket 2-3-1 and the service life of the first transmission belt 2-1-2.

[0036] To this end, in the present embodiment, the connecting bracket is designed as an articulated double-rod structure. When the first transmission belt 2-1-2 is not deformed, a stable triangular structure is formed between the two connecting rods 2-3-2 and the first transmission belt 2-1-2, which can provide stable support for the pallet bracket 2-3-1. When the first transmission belt 2-1-2 is deformed, resulting in a change in the distance between the two mounting seats 2-3-3, the two connecting rods 2-3-2 can rotate accordingly without resisting the deformation of the first transmission belt 2-1-2, thereby improving the movement stability of the pallet bracket 2-3-1 and the service life of the first transmission belt 2-1-2.

[0037] At the same time, since the pallet bracket 2-3-1 can rotate freely relative to the two connecting rods 2-3-2, when the pallet mounting assembly 2-3 passes through the turning areas at the top and bottom of the first transmission belt 2-1-2, the pallet bracket 2-3-1 can maintain a horizontal posture under the action of gravity.

[0038] A pallet mounting slide with one end open is provided on the pallet bracket 2-3-1. The length direction of the pallet mounting slide is parallel to the arrangement direction of the two circulating transmission components 2-1. The shape of the pallet mounting slide corresponds to the shape of the material transport pallet 3. The material transport pallet 3 can slide in the pallet mounting slide; the end of the pallet mounting slide close to the access port on the outer shell is open, so that the material transport pallet 3 can be easily loaded into the pallet bracket 2-3-1, and the material transport pallet 3 can be taken out from the pallet bracket 2-3-1. When the pallet bracket 2-3-1 reaches the middle access position of the frame 1 driven by the circulating transmission component 2-1, the access mechanism 3 can take out the material transport pallet 3 on the pallet bracket 2-3-1, or put the material transport pallet 3 on the pallet bracket 2-3-1.

[0039] This embodiment provides a preferred non-essential technical solution: a refrigeration module is installed in the housing. The refrigeration module is used to reduce the temperature in the housing and extend the shelf life of the sample food in the food sample box 4.

[0040] By using a controller to control the rotation angle of the motor, the designated tray bracket 2-3-1 can be controlled to move to a position aligned with the access port.

[0041] The working principle of the utility model is as follows:

[0042] When the food sample box 4 needs to be stored, the circulating transmission component 2-1 in the tray circulation mechanism 2 circulates to move one of the empty tray brackets 2-3-1 to the position of the access port. The user with storage authority opens the access door on the access port and sends the transport tray 3 with the food sample box 4 into the empty tray bracket 2-3-1 to complete the sample storage action.

[0043] When it is necessary to take out the designated food sample box 4, the circulating transmission component 2-1 in the tray circulation mechanism 2 circulates, so that the tray support 2-3-1 containing the designated food sample box 4 moves to the position of the access port; the user or supervisor with the taking-out authority opens the access door on the access port, reaches into the access port and pulls out the transport tray 3 containing the designated food sample box 4. The user can only take out the food sample boxes within his authority (for example, the food sample boxes whose retention period has expired).
