Technical Field

[0001] The utility model relates to cold storage equipment, in particular to a storage rack for cold storage. Background Art

[0002] The main function of cold storage is to keep perishable foods such as dairy products, meat, vegetables, fruits, flowers, medicines, chemical raw materials, electronic instruments, etc. at a constant temperature. In order to prevent the accumulation of items in the cold storage and the occurrence of backlogs or the inability to cool down the items in the middle, shelves are often used in the cold storage to classify and place the items in layers.

[0003] In the prior art, when the existing cold storage racks are used, the food position is fixed when the food is placed. If the food is placed for a long time, the placement surface that contacts the bottom of the food is likely to freeze, and it is inconvenient to take the food out when it needs to be taken out. In addition, in the cold storage, the food is generally placed directly on the rack, and the cold air in the cold storage cannot be concentrated on the rack to cool the food, resulting in poor food preservation effect. Now there is an urgent need for a cold storage rack to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a storage rack for a cold storage to solve the problems raised in the above-mentioned background technology.

[0009] Furthermore, an air guide plate is arranged at the bottom of the placement plate, a plurality of air blowing holes are opened at the top of the air guide plate, and a fan is arranged at the bottom of the air guide plate.

[0010] Furthermore, a hollow groove is provided inside the air guide plate for connecting the plurality of air blowing holes with the fan.

[0011] Furthermore, the rotating roller is placed between the laterally adjacent blowing holes, and the plurality of blowing holes are evenly distributed.

[0012] Furthermore, threaded holes are symmetrically provided on the top of the placement plate, and fixing bolts are provided on the top of the U-shaped limiting frame, which penetrate the U-shaped limiting frame and are inserted into the threaded holes.

[0013] Furthermore, positioning pins are symmetrically arranged on the top of the placement plate, and positioning holes are opened at positions corresponding to the positioning pins at the bottom of the U-shaped limiting frame, and the positioning pins match the positioning holes.

[0014] According to the utility model, a storage rack for a cold storage is provided, through the action of a belt and a pulley, a motor drives a plurality of rotating rollers to periodically rotate forward and reverse at the same time, and drives the food to reciprocate inside the U-shaped limiting frame, so as to avoid the food being fixed and the contact surface with the bottom of the food being frozen and affecting the subsequent removal.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, the utility model provides a technical solution: a storage rack for cold storage, comprising:

[0025] A plurality of connecting columns 1, at least one placement plate 4 is arranged between the plurality of connecting columns 1, and a moving wheel 101 is arranged at the bottom of the connecting column 1;

[0026] A through slot 41 is provided on the top of the placement plate 4, and a plurality of rotating rollers 6 placed inside the slot 41 are arranged inside the placement plate 4. A pair of pulleys 7 are longitudinally arranged on the side walls of the plurality of rotating rollers 6, and a belt 9 is arranged between the pulleys 7 adjacent to each other in the transverse direction. A motor 3 connected to one of the rotating rollers 6 and capable of periodic forward and reverse rotation is arranged on the side wall of the placement plate 4, and a U-shaped limit frame 5 is arranged on the top of the placement plate 4. This design drives the pulley 7 to rotate under the action of the belt 9 by making the motor 3 perform periodic forward and reverse rotation, and the rotation of the pulley 7 drives the rotating roller 6 to rotate. The belts 9 arranged between the pulleys 7 adjacent to each other in the transverse direction can rotate the pulleys 7 and the rotating rollers 6 rotate. Under the action of the belt 9, the rotational force is transmitted in sequence, so that the adjacent rotating rollers 6 rotate at the same time, so that the multiple rotating rollers 6 simultaneously perform periodic forward and reverse rotation to drive the food to move back and forth inside the U-shaped limit frame 5, so as to avoid the food being fixed and the contact surface with the bottom of the food being frozen and affecting the subsequent removal. Under the action of the rotation of the rotating rollers 6, the contact surface with the food is replaced, so that it will not be frozen, which plays a role in facilitating the subsequent removal of the food. At the same time, under the action of the reciprocating movement of the food, the uniformity of freezing is improved, the phenomenon that the position where the bottom of the food is contacted cannot be frozen is avoided, and the preservation effect of freezing is enhanced.

[0027] Reference Figure 2A material trough 51 connected to the through groove 41 is provided on the side wall of the U-shaped limit frame 5. A baffle 10 for shielding the material trough 51 is provided on the side wall of the U-shaped limit frame 5 through a rotating hinge 13. A butterfly bolt 11 is provided between the baffle 10 and the U-shaped limit frame 5. This design allows the baffle 10 to rotate along the rotating hinge 13 to disengage from the shielding of the material trough 51, thereby facilitating the removal of food from the material trough 51 under the action of the rotating roller 6, further facilitating the removal of food. The butterfly bolt 11 is used to improve the stability of the connection between the baffle 10 and the U-shaped limit frame 5, shield the material trough 51, and prevent food from falling from the material trough 51 during frozen storage. The material trough 51 and the rotating roller 6 are parallel to each other.

[0028] Reference Figure 4 and Figure 5 A wind guide plate 2 is provided at the bottom of the placement plate 4, a plurality of blowing holes 21 are provided at the top of the wind guide plate 2, and a fan 12 is provided at the bottom of the wind guide plate 2. This design enables the fan 12 to work to centrally guide the cold air in the cold storage to the inside of the wind guide plate 2 and blow it out from the blowing holes 21, thereby centrally cooling the food for preservation and enhancing the freezing preservation effect. At the same time, the reciprocating movement of the rotating roller 6 on the food can evenly and fully cool the bottom of the food, further enhancing the preservation effect. A hollow groove is provided inside the wind guide plate 2 for connecting the plurality of blowing holes 21 with the fan 12. This design facilitates the wind generated by the fan 12 to be blown out from the plurality of blowing holes 21 at the same time through the hollow groove.

[0029] Reference Figure 2 and Figure 4 The rotating roller 6 is placed between the laterally adjacent blowing holes 21, and the plurality of blowing holes 21 are evenly distributed, thereby improving the rationality of the design.

[0030] Reference Figure 2 and Figure 3 , threaded holes 14 are symmetrically provided on the top of the placement plate 4, and a fixing bolt 8 is provided on the top of the U-shaped limit frame 5, which passes through the U-shaped limit frame 5 and is inserted into the threaded hole 14. This design improves the stability of the connection between the placement plate 4 and the U-shaped limit frame 5 by threading the fixing bolt 8 with the threaded hole 14, and avoids loosening of the connection. Positioning pins 15 are symmetrically provided on the top of the placement plate 4, and positioning holes are provided at positions corresponding to the positioning pins 15 at the bottom of the U-shaped limit frame 5. The positioning pins 15 match the positioning holes. This design avoids side slipping between the U-shaped limit frame 5 and the placement plate 4 by using the positioning pins 15 to connect with the positioning holes, and at the same time positions the connection between the fixing bolt 8 and the threaded hole 14 to improve the connection accuracy.

[0031] Reference Figure 1-Figure 5As an embodiment of the present invention: when food needs to be placed for cooling and preservation, the staff applies force to the baffle 10 to rotate the baffle 10 along the rotating hinge 13 to disengage the blocking of the material trough 51, and then puts the food into the material trough 51, so that the motor 3 works to drive the rotating roller 6 to rotate, and the rotating roller 6 rotates to drive the pulley 7 to rotate, and the pulley 7 rotates to drive the adjacent rotating roller 6 to rotate under the action of the belt 9, and the adjacent rotating roller 6 rotates under the action of the belt 9 and the pulley 7 to drive the remaining rotating rollers 6 to rotate at the same time, so as to send the food from the material trough 51 to the inside of the U-shaped limit frame 5. When the food is placed, the baffle 10 is closed and the baffle 10 and the U-shaped limit frame 5 are fixed together by the butterfly bolt 11. The connection is fixed to shield the material trough 51 to prevent food from falling from the material trough 51 during frozen storage. Under the action of the periodic forward and reverse rotation of the motor 3, multiple rotating rollers 6 are driven to periodically forward and reverse at the same time, thereby driving the food to reciprocate inside the U-shaped limit frame 5 to prevent the food from being fixed and the contact surface with the bottom of the food from freezing and affecting the subsequent removal. Under the action of the rotation of the rotating roller 6, the contact surface with the food is replaced so that it will not freeze, which plays a role in facilitating the subsequent removal of the food. At the same time, under the action of the reciprocating movement of the food, the uniformity of freezing is improved, the phenomenon that the position where the bottom of the food is contacted cannot be frozen is avoided, and the preservation effect of freezing is enhanced. Among them, the periodic forward and reverse rotation of the motor 3 is a prior art.

[0032] Then, the fan 12 is operated to guide the cold air in the cold storage to the inside of the air guide plate 2, and blown out from the multiple blowing holes 21 through the hollow groove, so as to centrally cool the food for preservation and enhance the freezing preservation effect. At the same time, the reciprocating movement of the rotating roller 6 on the food can evenly and fully cool the bottom of the food, further enhancing the preservation effect.

[0033] When the food needs to be taken out, the butterfly bolt 11 is screwed to loosen the baffle 10 and the U-shaped limit frame 5, and then force is applied to the baffle 10 to make it lose its shielding of the material trough 51, so that the motor 3 works to drive the rotating roller 6 to rotate and deliver the food to the material trough 51, thereby facilitating the food taking out operation and improving the practicality of the utility model.
