[0012] Furthermore, the elastic buffer assembly includes a sliding seat, which is slidably mounted inside the mounting chamber, a sliding connection block is fixedly mounted on one side of the sliding seat, the sliding connection block is slidably mounted in the slide groove, and two ear plates are fixedly mounted on the outer side of the sliding connection block, a connecting shaft is rotatably mounted between the two ear plates, a connecting block is fixedly mounted on the connecting shaft, and one end of the connecting block is fixedly connected to the buffer plate;

[0013] An end plate is fixedly mounted on the end of the connecting shaft, and a torsion spring is also sleeved on the end of the connecting shaft and is located between the end plate and the ear plate. One end of the torsion spring is fixedly connected to the ear plate, and the other end of the torsion spring is fixedly connected to the end plate. A limit stopper located on the back of the buffer plate is also fixedly mounted on the outer side of the sliding connection block, and the buffer plate can abut against the limit stopper under the torsional elastic force of the torsion spring.

[0014] Driven by the spacing adjustment assembly, the plurality of sliding seats can move and expand along the installation chamber toward the loading end of the roller frame, or move and shrink toward the unloading end of the roller frame.

[0015] Furthermore, the spacing adjustment assembly includes two screw rods, two sets of cross-links and a rotation drive unit. The two screw rods are rotatably installed in the installation chambers inside the cross beams on both sides respectively. A through hole for the screw rods to pass through is opened on the sliding seat in the installation chamber, and a threaded sleeve connected to the screw rod thread transmission is fixedly installed in the through hole of the rightmost sliding seat. The rotation drive unit can drive the two screw rods to rotate synchronously.

[0016] The two groups of cross-links are respectively arranged in the installation chambers inside the cross beams on both sides, and the multiple sliding seats in the installation chambers are evenly distributed along the cross-links and are rotatably connected to the cross fulcrums of the cross-links in turn. The left end of the cross-link is positioned on a connecting plate, and the positioning connecting plate is fixedly installed on the left end wall of the installation chamber.

[0017] Furthermore, the rotation drive unit includes a motor, an intermediate shaft and two transmission shafts. The intermediate shaft is rotatably installed inside the unloading end of the roller frame. Driven bevel gears are fixedly installed at both ends of the intermediate shaft. The transmission shaft is rotatably installed on one side of both ends of the intermediate shaft. A transmission bevel gear that is meshed and transmission-connected with the driven bevel gear is fixedly installed on the transmission shaft. Synchronous wheels are fixedly installed on one end of the transmission shaft and the screw rod. The corresponding two synchronous wheels are connected by a synchronous belt transmission.

[0019] The present invention also discloses a method for refrigerating raw materials for preparing fish and rice cake rolls, which comprises the following specific steps:

[0020] The spacing between the buffer plates is adjusted by the spacing adjustment component so that the spacing between the buffer plates is slightly larger than the length of the cargo box loaded with the raw materials for preparing fish and rice cake rolls. When the raw materials are refrigerated, the cargo box loaded with raw materials is placed on the roller rack from the loading end of the roller rack by a forklift, and then the cargo box can slide to the other end along the inclined roller rack. When the cargo box moves past the buffer plate position, the cargo box can abut and rotate the buffer plate. At this time, the elastic buffer component can provide torsional buffer elastic force for the buffer plate and the cargo box to buffer the cargo box, and when the cargo box passes the buffer plate position, the buffer plate can rotate and reset under the torsional elastic force of the elastic buffer component to buffer the next round of cargo boxes until the cargo box moves to the unloading end of the roller rack, and the cargo box is abutted and stopped by the material blocking member, and this reciprocating process is continued, and the cargo boxes are continuously placed from the loading end, so that the cargo boxes are moved and arranged in sequence on the roller rack until the raw materials are put into storage and refrigerated.

[0021] When raw materials need to be taken, the cargo box at the unloading end of the roller rack is first unloaded by a forklift. At this time, the cargo box on the roller rack moves down along the roller rack until the cargo box again abuts against the material blocking piece at the unloading end of the roller rack. Then the cargo box at the unloading end of the roller rack is unloaded again by a forklift, and this process is repeated until the unloading and material taking process is completed.

[0022] The present invention has the following beneficial effects:

[0023] The refrigerated shelves of the cold storage are provided with an inclined roller rack, and when the goods need to be refrigerated and stored, the goods can be placed on the roller rack in sequence at the inclined upward end of the roller rack, and then the goods can be slid along the roller rack to the inclined downward end in sequence until the shelves are full of goods. The goods can be placed on the roller rack from one end of the roller rack by the inclined roller rack, so that there is no need to move along the refrigerated shelves during the placing process, which not only makes the goods placing process more convenient and quick, but also improves the refrigeration efficiency of goods placing and storing, and at the same time, no operating space is required between adjacent shelves, which can improve the shelf placement density and space utilization rate of the refrigerated room, thereby improving the refrigeration capacity of the refrigeration equipment; and when taking out goods, all the goods on the roller rack can be taken out in sequence at the inclined downward end of the roller rack, making the taking out process more convenient, and at the same time, loading and taking out are respectively carried out at both ends of the roller rack, so that the goods placed first can be taken out first, which is convenient for controlling the refrigeration taking out time of the goods.

[0024] 2. In the present invention, buffer plates and elastic buffer components are evenly distributed at both ends of the roller frame. When the goods move past the buffer plate position, the goods can abut the buffer plate and rotate. At this time, the elastic buffer component can provide torsional buffering elastic force for the buffer plate and the goods to buffer and slow down the goods, thereby preventing the goods from being damaged by impact due to excessive speed when being transported on the roller frame.

[0025] 3. In the present invention, the spacing of the buffer plates can be adjusted through the spacing adjustment component, so that the spacing between the buffer plates is slightly larger than the length of the goods, so that when the goods are placed on the roller rack, multiple buffer plates can be isolated between the corresponding goods in turn, preventing collisions between adjacent goods when the goods are moved and transported to the storage position, thereby further improving the safety of the goods during transportation and storage.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0044] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention. Example 1

[0045] See also Figure 1-Figure 3 As shown, the present invention is a refrigeration device, including a refrigeration room 1, wherein a refrigeration shelf 2 is installed inside the refrigeration room 1, and the refrigeration shelf 2 includes a main frame 21, and a plurality of inclined roller frames are installed on the main frame 21, the upward inclined end of the roller frame is the loading end, and the downward inclined end of the roller frame is the unloading end, and the roller frame can transport the goods stacked from the loading end to the unloading end, and the unloading end is fixedly installed with a material blocking member; a buffer mechanism 3 is also installed on the main frame 21 and is located on the side of the roller frame, and the buffer mechanism 3 includes a plurality of buffer plates 32, a plurality of elastic buffer components and a spacing adjustment component, and the plurality of buffer plates 32 are equidistantly installed above the side of the roller frame through a plurality of elastic buffer components, and the elastic buffer component can provide a torsional buffering elastic force when the buffer plate 32 is impacted, and the spacing adjustment component can simultaneously drive the plurality of buffer plates 32 to move to adjust the spacing between adjacent buffer plates 32, and the plurality of buffer plates 32 always maintain an equidistant distribution during movement and adjustment;

[0046] Specifically, when the goods need to be refrigerated and stored by the refrigeration device, the spacing between the buffer plates 32 is first adjusted by the spacing adjustment component so that the spacing between the buffer plates 32 is slightly larger than the length of the cargo box loaded with goods. Then, the cargo box is placed on the roller rack from the loading end of the roller rack by a loading tool such as a forklift. Then, the cargo box slides to the other end along the inclined roller rack. When the cargo box moves past the position of the buffer plates 32, the cargo box abuts against the buffer plates 32 and rotates. At this time, the elastic buffer component can provide torsional buffering elastic force for the buffer plates 32 and the cargo box to buffer and decelerate the cargo box. When the cargo box passes the position of the buffer plates 32, the buffer plates 32 can rotate and reset under the torsional elastic force of the elastic buffer component to buffer the next round of cargo boxes until the cargo boxes move to the unloading end of the roller rack and are stopped by the material stopper, and the cargo boxes are placed from the loading end continuously, so that the cargo boxes are moved and arranged in sequence on the roller rack until the goods are put into storage and refrigerated; when the raw materials need to be taken, the cargo boxes at the unloading end of the roller rack are first unloaded by a forklift, and the cargo boxes on the roller rack move downward along the roller rack until the cargo boxes again abut against the material stopper at the unloading end of the roller rack, and then the cargo boxes at the unloading end of the roller rack are unloaded by a forklift again, and the process of unloading and taking materials is repeated.

[0047] The goods can be placed on the roller rack by an inclined arrangement, and all the goods on the roller rack can be placed from one end of the roller rack without moving along the refrigerated shelf 2. This not only makes the goods placement process more convenient and quick, but also improves the refrigeration efficiency of goods placement. At the same time, there is no need to leave operating space between adjacent shelves, which can increase the shelf placement density and space utilization rate of the refrigerated room 1, thereby increasing the refrigeration capacity of the refrigeration equipment. When taking out goods, all the goods on the roller rack can be taken out in turn at the unloading end of the roller rack, making the taking out process more convenient. At the same time, loading and unloading can be carried out at both ends of the roller rack, so that The goods that are placed first can be taken out first, which is convenient for controlling the refrigerated retrieval time of the goods; the buffer plates 32 and the elastic buffer components are used to buffer and slow down the goods being placed and transported, preventing the goods from being damaged by impact due to excessive speed when being transported on the roller rack; the spacing of the buffer plates 32 is adjusted by the spacing adjustment component, so that the spacing between the buffer plates 32 is slightly larger than the length of the goods, so that when the goods are placed on the roller rack, multiple buffer plates 32 can be isolated between the corresponding goods in turn, preventing collisions between adjacent goods when the goods are moved and transported to the storage position, further improving the safety of the goods during transportation and storage. Example 2

[0048] See also Figure 1 、 Figure 14As shown, the difference between this embodiment and the above embodiment is that a refrigerator 11 is installed at the top of the cold storage room 1, and sealed doors 12 are installed at both ends of the cold storage room 1; wherein, the refrigerator 11 is used to cool the cold storage room 1, and the two sealed doors 12 are respectively located at the loading end and unloading end of the refrigerated shelf 2, so as to facilitate entering the corresponding loading and unloading positions in the cold storage room 1 through the sealed doors 12. Example 3

[0049] See also Figure 2 、 Figure 3 As shown, the difference between this embodiment and the above embodiment is that the roller frame includes a support frame 22, which is obliquely mounted on the main frame 21, and a plurality of supporting conveying rollers 23 arranged in sequence are rotatably mounted on the inner ring of the support frame 22; the material blocking member includes a plurality of material blocking plates 24, which are symmetrically distributed and fixedly mounted on the top surface of the support frame 22 inclined downward;

[0050] When placing goods for refrigeration, the goods are placed in sequence from the upward end of the support frame 22 to the top surface of the support conveyor roller 23. At this time, the goods are transported along the support conveyor roller 23 to the downward end of the support frame 22 under the action of their own gravity until the goods abut against the baffle plate 24. After that, the subsequent goods are transported and abutted on the support conveyor roller 23 in sequence until the placement of the goods is completed or the support conveyor roller 23 is full of goods; and when driving the goods, the goods abutting on the baffle plate 24 are first lifted up and removed, and then the goods on the support conveyor roller 23 continue to be transported toward the baffle plate 24, so that the goods can be continuously lifted and removed at the position of the baffle plate 24, realizing the fixed-point unloading of goods. Example 4

[0051] See also Figure 4-Figure 7 As shown, the difference between this embodiment and the above embodiment is that the buffer mechanism 3 also includes a crossbeam 31, which is fixedly mounted on the main frame 21 and located on both sides above the roller frame, and an installation chamber 35 is provided inside the crossbeam 31, and a slide groove 34 communicating with the installation chamber 35 is opened on the inner side of the crossbeam 31, and the elastic buffer component is slidably mounted inside the installation chamber 35 and extends to the inner side of the crossbeam 31 through the slide groove 34; the elastic buffer component includes a sliding seat 36, which is slidably mounted inside the installation chamber 35, and a sliding connecting block 33 is fixedly mounted on one side of the sliding seat 36, and the sliding connecting block 33 is slidably clamped in the slide groove 34, and two ear plates 37 are fixedly mounted on the outer side of the sliding connecting block 33, and a connecting shaft 310 is rotatably mounted between the two ear plates 37, and a connecting block 311 is fixedly mounted on the connecting shaft 310, and one end of the connecting block 311 is fixedly connected to the buffer plate 32;

[0052] An end plate 38 is fixedly mounted on the end of the connecting shaft 310. A torsion spring 39 is also mounted on the end of the connecting shaft 310 between the end plate 38 and the ear plate 37. One end of the torsion spring 39 is fixedly connected to the ear plate 37, and the other end of the torsion spring 39 is fixedly connected to the end plate 38. A limit stopper 316 located on the back of the buffer plate 32 is also fixedly mounted on the outer side of the sliding connection block 33. The buffer plate 32 can abut against the limit stopper 316 under the torsional elastic force of the torsion spring 39. The multiple sliding seats 36 can move and expand along the installation chamber 35 toward the loading end of the roller frame, or move and contract toward the unloading end of the roller frame under the drive of the spacing adjustment component.

[0053] When the goods are transported along the supporting conveyor roller 23 in an inclined downward direction and pass through the position of the buffer plate 32, the goods abut the buffer plate 32 through the side and rotate. At the same time, the buffer plate 32 drives the connecting shaft 310 and the end plate 38 to rotate synchronously, so that the end plate 38 drives the torsion spring 39 to torsion deformation, thereby buffering the buffer plate 32 and the goods through the torsional elastic force of the torsion spring 39. After the goods pass through the buffer plate 32, the connecting shaft 310 and the end plate 38 rotate and reset under the action of the torsional elastic force of the torsion spring 39, and drive the buffer plate 32 to reset until the back side of the buffer plate 32 abuts against the back side of the limit block 316 again. Example 5

[0054] See also Figure 4-11 As shown, the difference between this embodiment and the above embodiment is that the spacing adjustment assembly includes two screw rods 318, two groups of cross links 320 and a rotation drive unit, the two screw rods 318 are rotatably installed in the installation chambers 35 inside the cross beams 31 on both sides, the sliding seat 36 in the installation chamber 35 is provided with a through hole 319 for the screw rod 318 to pass through, and a threaded sleeve 317 that is threadedly connected to the screw rod 318 is fixedly installed in the through hole 319 of the rightmost sliding seat 36, and the rotation drive unit can drive the two screw rods 318 to rotate synchronously; the two groups of cross links 320 are respectively arranged in the installation chambers 35 inside the cross beams 31 on both sides, and the multiple sliding seats 36 in the installation chamber 35 are equidistantly distributed along the cross links 320 and are rotatably connected to the cross fulcrums of the cross links 320 in turn, the left end of the cross links 320 is positioned at a connecting plate 322, and the positioning connecting plate 322 is fixedly mounted on the left end wall of the installation chamber 35;

[0055] When the distance between adjacent buffer plates 32 needs to be adjusted according to the length of the cargo, the two screw rods 318 are driven to rotate synchronously by the rotary drive assembly. When the screw rod 318 rotates, the threaded sleeve 317 thereon is driven to move left or right through the threaded transmission. When the threaded sleeve 317 moves to the left, the threaded sleeve 317 drives the rightmost sliding seat 36 and the buffer plate 32 to move to the left. At this time, the rightmost sliding seat 36 drives the cross link 320 to move to the left and retract, thereby driving the other sliding seats 36 in the installation chamber 35 to move to the left synchronously through the cross link 320, thereby making The multiple buffer plates 32 on the inner side of the beam 31 move synchronously to the left and shrink to adjust and reduce the spacing between adjacent buffer plates 32; accordingly, when the threaded sleeve 317 moves to the right, the threaded sleeve 317 drives the rightmost sliding seat 36 and the buffer plate 32 to move to the right. At this time, the rightmost sliding seat 36 drives the cross-link 320 to move to the right and expand, thereby driving the other sliding seats 36 in the installation chamber 35 to move synchronously to the right through the cross-link 320, thereby making the multiple buffer plates 32 on the inner side of the beam 31 move synchronously to the right and expand to adjust and increase the spacing between adjacent buffer plates 32.

[0056] Furthermore, the rotation drive unit includes a motor 321, an intermediate shaft 325 and two transmission shafts 327. The intermediate shaft 325 is rotatably mounted inside the discharge end of the drum frame. Driven bevel gears 328 are fixedly mounted on both ends of the intermediate shaft 325. Transmission shafts 327 are rotatably mounted on one side of both ends of the intermediate shaft 325. Transmission bevel gears 326 that are meshed and transmission-connected with the driven bevel gears 328 are fixedly mounted on the transmission shaft 327. Synchronous wheels 324 are fixedly mounted on one end of the transmission shaft 327 and the lead screw 318. The corresponding two synchronous wheels 324 are transmission-connected via a synchronous belt 323. The motor 321 is fixedly mounted in the main frame 21 and transmission-connected to one of the lead screws 318.

[0057] When the rotation drive unit is working, the motor 321 drives one of the screw rods 318 to rotate, and the screw rod 318 drives the transmission shaft 327 to rotate synchronously through the transmission of the synchronous wheel 324 and the synchronous belt 323. Then, the transmission shaft 327 drives the intermediate shaft 325 to rotate synchronously through the meshing transmission of the transmission bevel gear 326 and the driven bevel gear 328. The intermediate shaft 325 then drives the transmission shaft 327 at the other end to rotate synchronously through the meshing transmission of the transmission bevel gear 326 and the driven bevel gear 328. The transmission drives the other screw rod 318 to rotate synchronously, so that through the coordinated transmission of the synchronous wheel 324, the synchronous belt 323, the transmission shaft 327, the intermediate shaft 325, the transmission bevel gear 326 and the driven bevel gear 328, the two screw rods 318 can be driven to rotate synchronously when the motor 321 is working, thereby driving the buffer plates 32 on both sides of the top of the support frame 22 to move and adjust synchronously, and due to the setting of the intermediate shaft 325, the arrangement of the rotation drive unit can bypass the unloading position above the support frame 22, so as not to affect the normal unloading of goods on the support frame 22. Example 6

[0058] See also Figure 4 、 Figure 5 、 Figure 12 、 Figure 13 As shown, the difference between this embodiment and the above embodiment is that a reversing block 313 is fixedly mounted on the end of the connecting shaft 310, a protrusion 315 is provided on the side of the reversing block 313 facing the crossbeam 31, an abutting limit surface 314 is provided on the front side of the reversing block 313, and a limit bar 312 corresponding to the reversing block 313 is fixedly mounted on the side of the crossbeam 31 located at the discharge end of the roller frame;

[0059] When the refrigerated goods to be stored are light in weight and have small gravitational potential energy, and do not need to be buffered by the buffer plate 32, the buffer plate 32 is driven by the rotary drive unit to move toward the unloading end of the roller rack and shrink and gather. When the buffer plate 32 moves to the position of the limit bar 312, the protrusion 315 at the inner end of the reversing block 313 abuts the end of the limit bar 312. Then, as the buffer plate 32 and the reversing block 313 continue to move, the reversing block 313 rotates under the abutment of the protrusion 315 and the end of the limit bar 312, and drives the connecting shaft 310 and the buffer plate 32 to rotate synchronously until the abutment limit surface 314 on one side of the reversing block 313 rotates and abuts the surface of the limit bar 312. At this time, the buffer plate 32 is folded on one side of the beam 31 to make the buffer plate 32 avoid the goods stored on the roller rack. Example 7

[0060] This embodiment discloses a method for refrigerating raw materials for preparing fish and rice cake rolls, and the specific steps are as follows:

[0061] When the container moves past the buffer plate 32, the buffer plate 32 can be rotated and reset under the torsional elastic force of the elastic buffer assembly to buffer the next round of container, until the container moves to the unloading end of the roller rack, and the container is stopped by the material stopper. In this way, the container is continuously placed from the loading end, so that the container moves and is arranged in sequence on the roller rack until the raw materials are put into storage and refrigerated.

[0062] When raw materials need to be taken, the cargo box at the unloading end of the roller rack is first unloaded by a forklift. At this time, the cargo box on the roller rack moves down along the roller rack until the cargo box again abuts against the material blocking piece at the unloading end of the roller rack. Then the cargo box at the unloading end of the roller rack is unloaded again by a forklift, and this process is repeated until the unloading and material taking process is completed.
