Description

Technical Field

[0001] This utility model belongs to the field of baking trolley technology, and in particular relates to a flip-type baking trolley capable of flipping and demolding operations. Background Technology

[0002] Most existing baking trolleys only have basic carrying and transport functions and lack auxiliary mechanisms designed for the demolding of baked goods. Therefore, after baking, operators still need to remove the baking trays from the baking trolley one by one and demold them manually, which is not only time-consuming and labor-intensive, but also prone to product deformation or damage due to inconsistent operating techniques.

[0003] Furthermore, since the surface temperature of the baking tray is extremely high when it comes out of the oven, operators must wear protective gloves to work on it. If there is a lack of stable support structure or guiding device during the removal of the baking tray, the baked goods are prone to falling off due to tilting, sliding or collision, which will affect the appearance integrity and product quality.

[0004] In addition, during the cooling process after demolding, if there is a lack of proper cooling support, it is often necessary to find an additional platform or container to place the baked goods, which interrupts the process and increases the risk of product contamination or damage. Summary of the Invention

[0052] Please see Figures 8 to 12As shown, when the baking rack 20 is in the first position, each baked item G is located on each baking tray T; when the baking rack 20 is flipped from the first position to the second position, an external force is used to pull each cooling tray support 60 in the opposite direction to the baking rack 20. Each cooling tray support 60 slides down along the first section 71 of each guide rail 70 to the third section 73 of each guide rail 70, causing each baked item G to separate from each baking tray T and be demolded onto each cooling tray C; the operator can first remove the stop pin P from the stop bar 30, and then remove the stop bar 30 from the assembly 27 and the positioning member 28, so that the cooling tray C carrying the baked item G can be removed from the baking rack 20.

[0053] In summary, this utility model can achieve the following effects:

[0054] 1. This utility model, through the flip-up baking rack 20 and the sliding cooling tray support 60, enables the baked goods G to be quickly demolded from the baking tray T and guided to the cooling tray C after baking, thereby improving the overall demolding efficiency and operational safety. Moreover, the demolding and cooling process is continuous and stable, which can effectively reduce manual intervention and damage risks. It is especially suitable for batch baking processes that require stable output, and has good practical application and industrial promotion value.

[0055] 2. The cooling tray support 60 of this utility model can slide in and out of the baking rack 20 along the guide rail 70, making the operation smoother. Moreover, the guide rail 70 has a three-section design with different heights. When flipped to the second position, the cooling tray support 60 is guided by gravity and external force to automatically slide to the lowest section position, thereby guiding the baked goods G to be successfully demolded into the cooling tray C.

[0056] 3. The base 10 of this utility model includes a bottom part 11 and two upright parts 12. The two upright parts 12 are respectively disposed on both sides of the bottom part 11, so that the overall structure is stable and has load-bearing capacity, which can support the operation of the flip baking rack 20, and at the same time ensure the stability of the baking rack 20 when switching between different angles.

[0057] 4. This utility model uses fastener 40 to lock onto baking rack 20 to prevent it from flipping. In conjunction with three sets of coaxial openings and detachable stop pin P on upright 12, fastener 40 and rotating shaft 26, baking rack 20 can be locked in a specific position to prevent accidental flipping during operation and further improve operational safety.

[0058] 5. When the baking rack 20 of this utility model is in the first position and the second position respectively, the first limiting block 234 and the second limiting block 235 set on the baking rack 20 can respectively abut against the two uprights 12 of the base 10 to form a stable positioning support, so as to prevent the baking rack 20 from tilting or swaying excessively after flipping, thereby effectively limiting the flipping angle and ensuring that each flipping operation can accurately stop at the predetermined position. This not only improves the overall structural stability, but also helps to improve the operational safety and consistency of repetitive operations.

[0059] 6. The first end side 24 and the second end side 25 of the baking rack 20 are respectively provided with a connecting part 27 and a positioning part 28. With the help of the insertable stop bar 30 and the stop pin P, the baking tray T and the cooling tray C can be properly positioned when placed on the support, avoiding slippage during flipping or pulling, protecting the baked goods G from displacement or falling, and increasing structural stability and practicality.

[0060] 7. This utility model precisely engages the second end 32 of the stop bar 30 with the positioning hole 281 of the positioning member 28, ensuring that the stop bar 30 is accurately and stably positioned after insertion, and enhancing the overall engagement stability.

[0061] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
