Description

Technical Field

[0001] The present application belongs to the technical field of material conveying equipment, and relates to the unloading of hot pot base materials, and is specifically related to a multi-layer cold chain unloading device for hot pot base materials. Background Art

[0002] Cold chain technology refers to the process in which food raw materials, food, special biological products or medicines, etc., after being inactivated, are kept in a specific low-temperature environment required by the product during processing, storage, transportation, distribution, retail and use to prevent them from spoiling and ensure food and drug safety. In the process of processing hot pot base, after the hot pot base is fried, it is generally shaped, packaged, packed, tested and other processes in the cold chain system, and finally sent out of the cold chain for temporary storage or boxing. Because the processing and transportation efficiency of hot pot base is low when a single cold chain is set up, and the hot pot base is easy to dissipate heat, the current hot pot base processing line is generally equipped with multiple layers of parallel cold chains. This not only improves the processing and transportation efficiency of the hot pot base, but also the parallel setting of multiple layers of cold chains can reduce the heat exchange area between the hot pot base and the outside world, making it difficult to dissipate heat and saving refrigeration energy consumption. However, when multiple cold chains are set up in parallel, if conventional manual unloading is continued as the hot pot soup base exits the cold chain, the unloading efficiency will not keep up with the transportation efficiency of multiple cold chains. In addition, the hot pot soup base is at a low temperature right after exiting the cold chain, and prolonged manual unloading can easily cause frostbite to the operators. The prior art also shows some mechanical devices that can be used to unload the hot pot soup base after it exits the cold chain, but these mechanical devices are generally only capable of unloading the hot pot soup base from a single cold chain, or there is a problem that the hot pot soup base is easily bumped during unloading, and they cannot match the unloading capacity required for processing and transporting the hot pot soup base in multiple cold chains.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] like Figure 1 、 Figure 2 、 Figure 4 As shown, this embodiment provides a multi-layer cold chain unloading device for hot pot base, including a conveyor belt 1, a material rack rod 2, and a lifting plate 3.

[0030] Specifically, such as Figure 1 As shown, the conveyor belt 1 is horizontally arranged at the outlet of the cold chain warehouse, and one end thereof extends out of the cold chain warehouse, which is used to convey the hot pot base out of the cold chain; in this example, three groups of conveyor belts 1 are provided at the outlet of the cold chain warehouse, and the three groups of conveyor belts 1 are arranged in an array along the vertical direction.

[0031] Specifically, such as Figure 2As shown, there are multiple pairs of material rack rods 2, and a pair of material rack rods 2 matches a conveyor belt 1. In this example, three groups of conveyor belts 1 are provided at the outlet of a single cold chain warehouse, so there are three pairs of conveyor belts 1; a horizontal bar 21 parallel to the width direction of the conveyor belt 1 is provided at a predetermined distance below the outlet end of each conveyor belt 1, and the predetermined distance should be small enough to enable the conveyor belt 1 to smoothly convey the hot pot base to the material rack rods 2, and the hot pot base can be placed flat on the material rack rods 2; the front side of the horizontal bar 21 is flush with the outlet end of the conveyor belt 1, and this design is also used to enable the conveyor belt 1 to smoothly convey the hot pot base to the material rack rods 2, and the horizontal bar 21 will not contact the hot pot base during transportation; the horizontal bar 21 has two first through holes arrayed along the width direction of the conveyor belt 1, and each pair of material rack rods 2 slides along the length direction of the conveyor belt 1 through the two first through holes on the corresponding horizontal bar 21.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, there are four lifting plates 3. In this example, the lifting plates 3 are all horizontally arranged outside the outlet end of the conveyor belt 1 to stably carry the hot pot base. The four lifting plates 3 are arranged in a circular array around a first rotating axis arranged in the vertical direction, and are rotated around the first rotating axis. The lifting plates 3 are all moved in the vertical direction. The vertical distances between the first rotating axis and the two side surfaces of the lifting plates 3 are equal, and the vertical distances between the first rotating axis and the material rack rod 2 are equal. The radius of the circular array of the lifting plates 3 matches the spacing between the horizontal bar 21 and the first rotating axis. This design is used to enable each lifting plate 3 to rotate to the bottom of the hot pot base on the material rack rod 2.

[0033] When working, the conveyor belt 1 conveys the hot pot soup base from one end thereof to the corresponding material rack rod 2, rotates the lifting plate 3, makes the lifting plate 3 be located just below the material rack rod 2, moves the lifting plate 3 upward, makes the upper surface of the lifting plate 3 contact with the material rack rod 2 located at the bottom, moves the material rack rod 2, reduces the length of the material rack rod 2 extending out of the side of the horizontal bar 21, until the protruding end of the material rack rod 2 enters the first through hole in the horizontal bar, in this process, the hot pot soup base first follows the material rack rod 2 to move, and contacts with the horizontal bar 21 during the movement. After the contact, the horizontal bar 21 will restrict the hot pot soup base to continue to move with the rack rod 2. At the same time, the hot pot soup base will be adjusted during the restriction process so that the side edges of the hot pot soup base are correspondingly parallel to the length and width directions of the conveyor belt 1. After the protruding end of the rack rod 2 completely enters the first through hole in the horizontal bar, the hot pot soup base is completely transferred from the rack rod 2 to the lifting plate 3; move the lifting plate 3 upward again so that the hot pot soup base on the lifting plate 3 contacts the rack rod 2 in the middle, and move the rack rod 2 in the middle. The material rod 2 is used to transfer the hot pot soup base on the material rack rod 2 in the middle to the lifting plate 3. At this time, the hot pot soup base on the lifting plate 3 is stacked and static; the lifting plate 3 is moved upward again to make the hot pot soup base on the upper layer of the lifting plate 3 contact the material rack rod 2 on the uppermost layer, and the material rack rod 2 on the uppermost layer is moved to transfer the hot pot soup base on the material rack rod 2 on the uppermost layer to the lifting plate 3 and stacked and static with the hot pot soup base already on the lifting plate 3; the lifting plate 3 is rotated to make the lifting plate carrying the hot pot soup base Plate 3 moves to the unloading point, and at the same time, another lifting plate 3 moves to the bottom of the rack rod 2 to unload again; the unloading of hot pot base at the unloading point can be completed by a simple mechanical device with a pushing or clamping function. The entire process of unloading the hot pot base from the conveyor belt 1 to the unloading point does not require manual participation, and can unload multiple layers of cold chain at one time, and the unloading of hot pot base at the unloading point can be carried out simultaneously with the unloading of hot pot base on the conveyor belt, which greatly improves the overall unloading efficiency.
