DETAILED DESCRIPTION

[0019] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0020] The freeze-dried food conveying device of the embodiments of the present application is described below with reference to the accompanying drawings.

[0021] As shown in the drawings, Figures 1-7 The freeze-dried food conveying device of the embodiments of the present application can include a conveyor 1, a material distributing mechanism 2, and an auxiliary mechanism 3.

[0022] The conveyor 1 is vertically arranged relative to the ground.

[0023] It should be noted that the conveyor 1 described in this embodiment can be a belt conveyor, which includes a frame body, a plurality of conveying rollers, a belt, and a driving device. The specific connection structure and working principle have been disclosed by the prior art, and therefore will not be described in detail here.

[0024] The frame body can be in contact with the ground through a support leg, which can reduce the contact area between the device and the ground, increase the pressure therebetween, and increase the stability of the device during use.

[0025] The material distributing mechanism 2 includes two material distributing roller assemblies 21, a transmission assembly 22, two linkage assemblies 23, a horizontal driving assembly 24, and a fixing plate 25.

[0026] Two cloth roller assemblies 21 are arranged above the conveyor 1, and each cloth roller assembly 21 comprises a tube body 211, a central rotating shaft 212 and a plurality of poking members 213.

[0027] The tube body 211 is sleeved outside the central rotating shaft 212, and the tube body 211 is in sliding connection with the central rotating shaft 212. The plurality of poking members 213 are arranged equidistantly and staggered on the tube body 211.

[0028] In the above embodiment, referring to Figure 4 , a spline is arranged between the central rotating shaft 212 and the tube body 211 to ensure synchronous rotation between the central rotating shaft 212 and the tube body 211.

[0029] It can be understood that the plurality of poking members 213 are arranged equidistantly and staggered on the tube body 211, which can avoid the situation that two poking members 213 simultaneously act on one end of a product, causing the product to be skewed and resulting in abutment between adjacent two products.

[0030] The transmission assembly 22 is connected with one end of the driving roller of the conveyor 1 and one end of the central rotating shaft 212, and the two linkage assemblies 23 are connected with two ends of the corresponding tube body 211.

[0031] It can be understood that the transmission assembly 22 can drive the central rotating shaft 212 to rotate by the power of the conveyor 1 to guide the product during the conveying process.

[0032] The auxiliary mechanism 3 is connected with the conveyor 1, the conveyor belt of the conveyor 1 penetrates through the auxiliary mechanism 3, and the auxiliary mechanism 3 is used for tensioning the belt of the conveyor 1 and cleaning the surface of the belt.

[0033] Specifically, during the freeze-drying process of food, the conveying device is arranged at the freeze-drying station and the packaging station, and the freeze-dried food (for example, fruits, vegetables, etc.) is conveyed by the conveying device.

[0034] When the device is started, the conveyor 1 runs in the clockwise direction, and the freeze-dried food moves at a constant speed under the action of the conveyor 1. The products stacked together are laid flat on the belt of the conveyor 1 by means of the blocking plate (not shown in the figure).

[0035] It should be noted that the blocking plate is installed on the conveyor 1, and the products with a height within the rated height (between 1-2 product heights) are allowed to pass between the bottom of the blocking plate and the belt of the conveyor 1, so that the products stacked together are laid flat on the conveyor 1.

[0036] The horizontal driving assembly 24 drives the cloth roller assembly 21 to move through the linkage assembly 23, the pipe body 211 slides on the central rotating shaft 212, and the pipe body 211 drives the plurality of shovels 213 to reciprocate.

[0037] At the same time, under the action of the transmission assembly 22, the cloth roller assembly 21 rotates at a constant speed, and guides the product during the conveying process. Especially for products with a certain length, the two ends of the product are spaced apart from other products by a certain distance, thereby ensuring the effect of vacuum drying sublimation and the processing efficiency of the product.

[0042] Specifically, in the process of the cloth roller assembly 21 moving, the electric telescopic rod 242 moves the adjusting rod 244 under the auxiliary action of the guide component 243, the adjusting rod 244 drives the two connecting rods 234 to move, and under the connecting action of the connecting plate 232 and the bearing 231, the pipe body 211 is further pushed to reciprocate outside the central rotating shaft 212.

[0043] When the connecting plate 232 moves, the connecting plate 232 can slide along the first guide rod 233, thereby ensuring the stability of the connecting plate 232 when moving.

[0044] In an embodiment of the present application, as shown in Figure 5 The guide component 243 includes a sliding seat 2431 and a guide rail 2432.

[0049] As a possible case, when it is needed to change the distance between the products on the conveyor 1, the adjusting rod 244 is rotated, the adjusting rod 244 is in threaded connection with the connecting rod 234, the linkage assembly 23 takes the first guide rod 233 as the rotation axis, the cloth roller assembly 21 is close to the surface of the conveyor 1, the rubber rod 2132 on the cloth roller assembly 21 is in contact with the conveyor 1 and is bent, the bent rubber rod 2132 swings left and right with the bent position as the center, and then the products are pushed to the two sides.

[0050] The distance between the two products is substantially the same as the horizontal moving distance of the pushing piece 213 and the horizontal swinging distance of the bent rubber rod 2132.

[0051] In another embodiment of the present application, as shown in the pushing piece 213 includes a sleeve ring 2131, a plurality of rubber rods 2132 and a fixing piece 2133. Figure 6

[0053] As another possible case, because the types of freeze-dried food are different, the time required for vacuum drying sublimation is also different, and the distance between the products on the conveyor 1 can be appropriately reduced, so that the conveyor 1 can transport more products in unit time, so as to improve the processing efficiency of the freeze-dried food.

[0054] By rotating the fixing piece 2133, the positions of the sleeve ring 2131 and the plurality of rubber rods 2132 can be moved. ​​
