Description

Technical Field

[0001] This utility model relates to the field of baking rack technology, and in particular to a raw material baking rack. Background Technology

[0002] In the processing of fish bait, drying, maturation, or hot air setting are key technological steps. These steps are usually completed in large drying ovens or baking ovens, which are equipped with multi-layer baking racks to hold the feed trays, enabling the batch and continuous production of fish bait.

[0003] Currently, the baking racks commonly used in the fish bait processing industry are mostly fixed-layer rack structures. That is, multiple parallel support racks are fixed within a main frame by welding or bolts, and the vertical spacing between each layer cannot be adjusted after manufacturing.

[0004] This fixed-gap structure is unsuitable for adapting to the complex and diverse processing needs of fish bait, as it cannot accommodate fish bait products of different physical states and sizes. Fish bait comes in a wide variety of types, with vastly different shapes and physical properties. For example, powdered baits with low density that require fluffy shaping need thinner layers and occupy less height; while larger, pellet or block baits require greater interlayer space. The fixed-gap baking rack cannot achieve flexible adaptation, resulting in low utilization of the oven's internal space and increased energy consumption when processing low-profile products; while when processing taller products, problems such as contact and deformation due to pressure may occur, leading to a higher defect rate.

[0005] Secondly, it severely restricts the optimization of production processes and the flow of hot air. Fish baits with different compositions and moisture contents have strict requirements for the uniformity of temperature and airflow during drying. Fixed-gap shelf structures create fixed air ducts, which may lead to uneven distribution of hot air inside the tank, causing localized overheating or dead air zones. This can result in some fish baits being under-dried or over-charred, affecting the consistency of product quality. Operators cannot optimize the hot air circulation efficiency within the tank by adjusting the gaps between shelves.

[0006] Therefore, the inherent problems of existing technologies limit the flexibility, energy economy, and product quality stability of fish bait processing and production. There is an urgent need for a baking rack that can flexibly adjust the interlayer spacing according to product type to improve the overall efficiency of fish bait processing lines. Utility Model Content

[0007] The purpose of this invention is to provide a raw material baking rack that allows for adjustment of the spacing between baking rack layers.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A raw material baking rack includes a base with four vertically fixed support columns at the four vertices of a rectangular plane. Placement plates are spaced parallel to each other on the four support columns, and material frames are placed on the placement plates. Locking devices are provided between the placement plates and the support columns to lock the placement plates at different heights to the support columns. A buffer is provided inside each support column to cushion the placement plates when the locking device is released.

[0009] As a further feature of this utility model, the locking component includes a locking bolt, and the support column is provided with a plurality of vertically spaced connecting holes. The placement plate has a threaded hole on the side facing the connecting holes, and the locking bolt is inserted into the connecting holes and threadedly connected to the placement plate through the threaded holes.

[0010] As a further feature of this utility model, the support column has an installation space inside, the buffer includes an airbag disposed in the installation space, the support column has a vertical groove on its side facing the placement plate, the groove communicates with the installation space, the placement plate has a connecting rod extending to the installation space, the connecting rod is fixedly connected to a collar, and the collar is sleeved on the airbag.

[0011] As a further feature of this invention, the airbag is connected to an inflation tube, and the air inlet of the inflation tube is equipped with a valve.

[0012] As a further feature of this invention, the locking element is disposed on a set of support columns located diagonally, and the buffer element is disposed on another set of support columns located diagonally.

[0013] As a further feature of this utility model, the placement plate is provided with first limiting plates on both sides, and the placement plate is provided with a second limiting plate on one side of the two first limiting plates. The two first limiting plates and the second limiting plate form a placement space for placing the material frame.

[0014] As a further feature of this invention, the placement plate is rotatably provided with a support rod on the side opposite to the second limiting plate, and one end of the support rod abuts against the material frame.

[0015] As a further feature of this utility model, the support rod includes an integrally formed long rod, a short rod, and a fixed rod. The long rod and the short rod are arranged in parallel and aligned at one end. The fixed rod is used to connect the aligned ends of the long rod and the short rod. The short rod is rotatably connected to the placement plate. One end of the long rod abuts against the material frame.

[0016] As a further feature of this invention, the base is provided with several omnidirectional wheels at its bottom.

[0017] The beneficial effects of this utility model are: This invention provides a baking rack with adjustable interlayer spacing. By setting multiple connection holes on the support column, each connection hole corresponds to an adjustable height. After the placement plate is moved to the target height, the placement plate and the support column are connected by locking bolts. The adjustment is convenient and the connection is stable.

[0018] This invention also includes a buffer component, which provides cushioning through the inflation and deflation of the airbag. Without the buffer component, the placement plate would fall directly when the height needs to be adjusted, potentially colliding with the lower placement plate and causing damage to the entire baking rack. The airbag prevents the placement plate from falling quickly. After removing the locking bolt, the airbag is deflated, causing the placement plate to descend slowly, reducing its descent speed. Once the placement plate has descended, it is adjusted to the desired height, locked with the locking bolt, the deflated airbag is stretched and then inflated again to complete the height adjustment of the placement plate.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] A raw material baking rack, reference Figure 1 and Figure 2 The baking rack includes a base 1 with casters 18 underneath for easy movement. Four support columns 2 are located on top of the base 1 at the four vertices of a rectangular plane. The four support columns 2 are connected to multi-layer placement boards 3, which are arranged in parallel and spaced apart. Material boxes 4 are placed on the placement boards 3 for placing baking materials.

[0023] A locking element is provided between the placement plate 3 and the support column 2 to lock the placement plate 3 and the support column 2. Specifically, the locking element includes a locking bolt 5. The support column 2 has several vertically spaced connecting holes 6. The placement plate 3 has a threaded hole on the side facing the connecting holes 6. The locking bolt 5 is inserted into the connecting hole 6 and threadedly connected to the placement plate 3 through the threaded hole. When it is necessary to adjust the position of the placement plate 3 to adjust the interlayer spacing of the baking rack, loosen the locking bolt 5 and remove it. Then adjust the height of the placement plate 3 to a suitable height, align the threaded hole on the placement plate 3 with the corresponding connecting hole 6 on the support column 2, and then insert the locking bolt 5 to fix it.

[0024] After removing the locking bolt 5, without external support, the placement plate 3 will fall directly and crash into the lower placement plate 3. Long-term impact will damage the baking rack. To further facilitate spacing adjustment, a buffer is installed in the support column 2. When the locking mechanism is released, the buffer cushions the placement plate 3. Specifically, the support column 2 has an installation space inside. The buffer includes an airbag 7 installed in the installation space. The support column 2 has a vertical groove 8 on its side facing the placement plate 3, which communicates with the installation space. The placement plate 3 has a connecting rod 9 extending into the installation space. A collar 10 is fixedly connected to the connecting rod 9 and fits onto the airbag 7. When the airbag 7 is fully inflated, the collar 10 is in close contact with the airbag 7, and the diameter of the collar 10 is smaller than the diameter of the airbag 7 at this time. This prevents slippage between the airbag 7 and the collar 10 when the locking mechanism is released, thus allowing the airbag 7 to support the placement plate 3 and preventing it from falling immediately. The airbag 7 was then deflated, causing it to collapse and become unable to support the placement plate 3. The placement plate 3 then descended slowly, thus providing a cushioning effect.

[0025] In this embodiment, among the four support columns 2, two support columns 2 that are opposite each other along the diagonal are grouped together. One group of support columns 2 is provided with a connecting hole 6 for connecting locking bolts 5, and the other group of support columns 2 is provided with an installation space for installing airbags 7. This diagonal grouping arrangement can achieve a higher fixing effect and a buffering effect.

[0026] Based on this, the two airbags 7 are connected to an inflation tube 11. A valve is provided at the end of the inflation tube 11. When the valve is open, the airbags 7 can be deflated or inflated; when the valve is closed, the airbags 7 remain inflated. In other embodiments, the valve can be replaced with a plug, which can also achieve the effect of closing and opening the inflation tube 11. A material frame 4 is placed on a placement plate 3. To ensure the stability of the material frame 4, first limiting plates 12 are provided on both sides of the placement plate 3. A second limiting plate 13 is provided on one side of the placement plate 3, located between the two first limiting plates 12. The two first limiting plates 12 and the second limiting plate 13 form a placement space for placing the material frame 4. The first limiting plates 12 and the second limiting plates 13 prevent the material frame 4 from moving, thus ensuring the stability of the material frame 4.

[0027] Furthermore, a support rod 14 is rotatably mounted on the side of the placement plate 3 opposite to the second limiting plate 13, with one end of the support rod 14 abutting against the material frame. The support rod 14 includes an integrally formed long rod 15, a short rod 16, and a fixing rod 17. The long rod 15 and the short rod 16 are arranged parallel to each other and aligned at one end. The fixing rod 17 is used to connect the aligned ends of the long rod 15 and the short rod 16. The short rod 16 is rotatably connected to the placement plate 3, and one end of the long rod 15 abuts against the material frame 4. When it is necessary to push the material frame 4 onto the placement plate 3, the support rod 14 is rotated to move the long rod 15 away from the entrance of the placement space, and then the material frame 4 is pushed in. The support rod 14 is rotated again to rotate the long rod 15 into the placement space. At this time, one end of the long rod 15 abuts against one side of the material frame 4. Through the support of the support rod 14, the four sides of the material frame 4 are supported, further ensuring the stability of the material frame 4.

[0028] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
