Description

Technical Field

[0001] The utility model relates to the technical field of moon cake making, in particular to a hot air rotary furnace for making moon cakes. Background Art

[0002] Mooncakes are a traditional Mid-Autumn Festival food. The production of mooncakes is divided into the steps of making dough, preparing fillings, wrapping and shaping, and baking. In order to meet market demand, the baking step in the existing mooncake processing process often uses a hot air rotary oven to bake the mooncakes.

[0003] Most of the existing hot air rotary ovens for making mooncakes first put the prepared mooncakes into the multi-layer trays of the baking cart, and then push the cart into the hot air rotary oven with a turntable inside, and the mooncakes on the trays are hot-baked by the multiple baking structures inside the hot air rotary oven. However, after the cart is pushed in, the existing hot air rotary oven is only stabilized by locking the cart wheels, and the bottom tray is aligned with the stainless steel structure with a smooth surface. When the turntable at the bottom of the cart starts to rotate, the cart will move due to inertia, causing the cart body to hit the internal structure of the hot air rotary oven, thereby causing damage to the hot air rotary oven. Therefore, we have proposed a hot air rotary oven for making mooncakes to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a hot air rotary oven for making mooncakes, so as to solve the problem of poor fixing effect of hot air rotary ovens for making mooncakes on the current market as proposed in the background art.

[0006] Preferably, the vertical transmission rod forms a gear movable structure at the center of the turntable through the first gear and the second gear respectively with the first rack rod and the second rack rod.

[0007] Preferably, the first elastic pieces are distributed on the extrusion plate at equal intervals, and limiting rods are provided at both ends of the extrusion plate.

[0008] Preferably, the bottom plate is connected to the limiting groove through a sliding groove structure, and the bottom plates on both sides are fixedly connected to the inclined ladder.

[0010] Preferably, the second elastic piece is fixed to the bottom of the upper rotating plate through an extrusion rod, and the extrusion rod is arranged inside the upper rotating plate through a spring.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the hot air rotary furnace for making mooncakes:

[0012] (1) A gear movable structure consisting of a transmission rod, a first gear, a second gear, a first rack rod, and a second rack rod is arranged at the bottom of the turntable, so that the extrusion plate in the outer limiting groove is movable through the extension of the first rack rod and the second rack rod, thereby squeezing the cart moving wheel entering the limiting groove, thereby fixing the gears on both sides through the extrusion force. At the same time, a first spring plate is arranged on the extrusion plate. The elastic force of the spring plate can make the left and right moving wheels have different positions in the limiting groove. After one side is squeezed, there is still a certain moving distance, thereby squeezing both sides. At the same time, it can also avoid the connection structure on both sides of the moving wheel from being affected by the extrusion plate, thereby increasing the extrusion area and improving stability.

[0013] (2) At the bottom of the limit slot, the bottom plate is connected to the bottom of the turntable by a fixed structure formed by the fixing block of the inclined ladder and the bolts and fixing slots. After a long period of use, the inclined ladder and the bottom plate can be replaced through the fixing structure at the bottom of the turntable to avoid excessive accumulation of oil stains on the inclined ladder and the bottom plate, which may cause the moving wheels of the cart to slip. At the same time, on the upper rotating plate at the top of the oven, a deformation structure is formed by the squeezing rod and the second spring sheet. After the cart enters the oven, the deformation structure can squeeze the cart, thereby improving the stability of the cart in the oven. BRIEF DESCRIPTION OF THE DRAWINGS

A turntable 2 is provided at the bottom of the oven 1, and a limiting slot 3 is provided on the turntable 2, and a vertical transmission rod 4 is provided in the turntable 2, a first gear 5 is provided on the vertical transmission rod 4, and the first gear 5 is connected to the first rack rod 6 below, and the first gear 5 is connected to the first rack rod 6 below. A second gear 7 is provided at the rear, and a second rack rod 8 is connected to the bottom of the second gear 7. Extrusion plates 9 are connected to the ends of both sides of the first rack rod 6 and the second rack rod 8, and a first elastic piece 10 is provided on the extrusion plate 9. A bottom plate 11 is provided at the bottom of the limiting groove 3, and an inclined ladder 12 is connected to the front end of the bottom plate 11, and a fixed block 13 is provided on the rear side of the inclined ladder 12. The fixed block 13 is connected to the first fixed groove 19 of the turntable 2, and a bolt 14 is provided in the first fixed groove 19. An upper rotating plate 15 is connected to the top of the oven 1, and an extrusion rod 16 is connected to the bottom of the upper rotating plate 15, and a spring 17 is provided at the end of the extrusion rod 16, and a second elastic piece 18 is provided at the bottom of the extrusion rod 16.

[0025] The vertical transmission rod 4 forms a gear movable structure with the first rack rod 6 and the second rack rod 8 at the center of the turntable 2 through the first gear 5 and the second gear 7 respectively, and the first rack rod 6 and the second rack rod 8 are arranged up and down, so that the first gear 5 and the second gear 7 are driven to rotate by the rotation of the vertical transmission rod 4, and the first rack rod 6 and the second rack rod 8 are driven to extend to both sides through the gear structure, so that the extrusion plate 9 is extruded outward to squeeze the cart wheels, and the vertical transmission rod 4 is driven by the motor for easy control, and the turntable 2 rotates back and forth inside the oven 1, so that it is convenient to energize the motor through wires.

[0026] The first spring pieces 10 are evenly spaced on the extrusion plate 9. The deformation of the first spring pieces 10 improves the coverage of the moving wheel, thereby avoiding obstruction by the connecting structure on the moving wheel. At the same time, the deformation of the spring pieces can make the left and right moving wheels in different positions in the limit groove 3. After one side is squeezed, there is still a certain moving distance, which facilitates the other side to be squeezed. Limiting rods are provided at both ends of the extrusion plate 9 to improve stability during movement.

[0027] The bottom plate 11 is connected to the limiting groove 3 through a sliding groove structure, so that the bottom plate 11 can be moved through the sliding groove, and the bottom plates 11 on both sides are fixedly connected to the inclined ladder 12, so that the bottom plate 11 can be quickly taken out through the inclined ladder 12.

[0028] The inclined ladder 12 is fixedly connected to the first fixing groove 19 at the bottom of the turntable 2 by a fixing block 13 and a bolt 14, and the fixing block 13 and the first fixing groove 19 are threadedly connected to the bolt 14, so that the inclined ladder 12 can be fixed to the bottom of the turntable 2 by the bolt 14, making it convenient to replace the inclined ladder 12 and the base plate 11.

[0029] The second elastic piece 18 is fixed to the bottom of the upper rotating plate 15 by the squeezing rod 16, and the squeezing rod 16 is arranged inside the upper rotating plate 15 by the spring 17, so that the squeezing rod 16 and the second elastic piece 18 can contract when squeezed, thereby squeezing the cart by the reaction force of the second elastic piece 18 and the spring 17. At the same time, the spring 17 and the second elastic piece 18 will not produce excessive deformation under each external force, so that after being pushed under the second elastic piece 18, it can continue to be squeezed by the reaction force of the second elastic piece 18 and the spring 17 without loosening due to rotation.

[0030] Working principle: When using the hot air rotary oven for making mooncakes, first, push the mooncake-carrying cart into the limit slot 3 on the turntable 2 through the inclined ladder 12 at the bottom of the turntable 2, then lock the moving wheel, and then start the motor in the turntable 2, so that the motor drives the vertical transmission rod 4 at the center of the turntable 2 to rotate, thereby driving the first gear 5 and the second gear 7 on the vertical transmission rod 4 to rotate, and the rotation of the first gear 5 and the second gear 7 will drive the first rack rod 6 and the second rack rod 8 at the bottom to extend outward, thereby pushing the extrusion plate 9 outside the first rack rod 6 and the second rack rod 8 outward, and the extrusion plate 9 moves outward. At the same time, the first elastic sheet 10 on the surface of the extrusion plate 9 will wrap the moving wheels on both sides, thereby squeezing the locked moving wheels outward, so that the bottom of the cart is fixed on the turntable 2;

[0031] As the cart enters the oven 1, the squeezing rod 16 and the second elastic piece 18 on the lower side of the upper rotating plate 15 on the top of the oven 1 also contract and deform due to the squeezing of the top of the cart. The spring 17 at the end of the squeezing rod 16 and the second elastic piece 18 then squeeze the top of the cart, thereby fixing the cart in the oven 1.

[0032] The cam 12 is then released from the locking mechanism 13 and the locking mechanism 14 is engaged, and the cam 12 is engaged with the locking mechanism 13. The cam 12 is engaged with the locking mechanism 13 and the locking mechanism 13 is engaged, and the cam 12 is engaged with the locking mechanism 13.
