[0032] The embodiment of the present utility model provides a lifting and conveying mechanism and a food processing device, which can realize the continuous conveying of materials such as naked cakes and can make full use of the three-dimensional space to reduce the floor area.

[0033] The following combines Figures 1-6 to elaborate on the technical solutions provided by the present utility model in more detail.

[0034] Embodiment 1:

[0035] The lifting and conveying mechanism provided by the utility model comprises a frame, a first chain 1, a second chain 2, chain plates (the chain plates include an upper layer chain plate 3 and a lower layer chain plate 4), an upper sprocket, a reversing sprocket and a lower sprocket which are rotatably connected to the frame in sequence from top to bottom. Among them: on one side of the frame, the first chain 1 is wound around all the upper sprockets, one of the reversing sprockets and all the lower sprockets, and the second chain 2 is wound around one of the upper sprockets, the other reversing sprocket and all the lower sprockets; the chain plates are used for supporting the objects to be conveyed, and the chain plates include an upper layer chain plate 3 and a lower layer chain plate 4. Both ends of the upper layer chain plate 3 and both ends of the lower layer chain plate 4 are respectively fixedly connected to the first chain 1 and the second chain 2. Both the upper layer chain plate 3 and the lower layer chain plate 4 can be wound around the corresponding upper sprocket or reversing sprocket or lower sprocket, and thus vertically lift along with the movement of the first chain 1 and the second chain 2.

[0036] Specifically, as shown in Figure 1 the lifting and conveying mechanism of this embodiment has a symmetrical structure on both sides of the frame, that is, both opposite sides of the frame are Figure 1 the structure shown in. Both opposite sides of the upper layer chain plate 3 and the lower layer chain plate 4 are fixed to the corresponding chains.

[0037] In this embodiment, one side of the frame has two chains, and the whole has four chains. There are at least two upper layer chain plates 3 and lower layer chain plates 4 in total, and three, four, etc. can also be set. When a larger number of chain plates are set, the conveying efficiency of materials can be further improved.

[0038] In the lifting and conveying mechanism of this embodiment, both the upper layer chain plate 3 and the lower layer chain plate 4 can be wound around the corresponding upper sprocket or reversing sprocket or lower sprocket, and thus vertically lift along with the movement of the first chain 1 and the second chain 2. The upper layer chain plate 3 can receive multiple rows of naked cakes 300 of the feeding belt conveying mechanism 100, and the lower layer chain plate 4 throws the multiple rows of naked cakes 300 to the discharging belt conveying mechanism 200. Since the upper layer chain plate 3 and the lower layer chain plate 4 can vertically lift along with the movement of the first chain 1 and the second chain 2, therefore, the upper layer chain plate 3 and the lower layer chain plate 4 can be mutually converted to alternately complete the material receiving and feeding work, so as to realize the continuous conveying of materials such as the naked cakes 300. And this lifting and conveying mechanism can make full use of the three-dimensional space and reduce the floor area.

[0039] The lifting and conveying mechanism of this embodiment can be applied to the production and manufacture of biscuits, such as soft-core stuffed cookies. Hereinafter, taking the conveying of biscuits as an example for illustration, but this mechanism is not limited to being applied to biscuits.

[0040] As shown in Figure 1 , on one side of the frame, the upper sprocket includes a first upper sprocket 51 and a second upper sprocket 52, and the first upper sprocket 51 and the second upper sprocket 52 are arranged at intervals in the same horizontal plane. As shown in Figure 1, on one side of the frame, the reversing sprockets include a first reversing sprocket 61 and a second reversing sprocket 62. The first reversing sprocket 61 and the second reversing sprocket 62 are located in the same horizontal plane and are arranged in parallel, and the wheel bodies of the first reversing sprocket 61 and the second reversing sprocket 62 are located in different vertical planes; the first reversing sprocket 61 is located on the front side of the conveyance of the first upper sprocket 51, and the second reversing sprocket 62 is located on the front side of the conveyance of the second upper sprocket 52. See Figure 1 , on one side of the frame, the lower sprockets include a first lower sprocket 71 and a second lower sprocket 72. The first lower sprocket 71 and the second lower sprocket 72 are arranged at intervals in the same horizontal plane; the first lower sprocket 71 is located on the front side of the conveyance of the first reversing sprocket 61, the second lower sprocket 72 is located below the first upper sprocket 51, the first chain 1 is wound around the first lower sprocket 71 after being reversed by the first reversing sprocket 61, and the second chain 2 is wound around the first lower sprocket 71 after being reversed by the second reversing sprocket 62.

[0041] Among them, "front side of conveyance" refers to the direction along the conveyance of the biscuits. See Figure 1 , Figure 1 The direction of the hollow arrow in the figure indicates the conveyance direction of the biscuits, and the direction of the solid arrow indicates the moving direction of the chain.

[0042] See Figure 1 and Figure 2 As shown in and, the lifting and conveying mechanism of this embodiment further includes a driving shaft 7. The lower sprockets are fixed on the opposite sides of the driving shaft 7. A driving device such as a motor drives the driving shaft 7 to rotate, so as to drive the lower sprockets to rotate. Specifically, the first lower sprocket 71 and the second lower sprocket 72 are the driving shaft 7, the first upper sprocket 51, the second upper sprocket 52, the first reversing sprocket 61 and the second reversing sprocket 62 are all driven wheels.

[0043] See Figure 1 and Figure 2 As shown in and, the first chain 1 is wound around the first upper sprocket 51, the first reversing sprocket 61, the first lower sprocket 71, the second lower sprocket 72, and the second upper sprocket 52, and the second chain 2 is wound around the second upper sprocket 52, the second reversing sprocket 62, the first lower sprocket 71, and the second lower sprocket 72; the second upper sprocket 52, the first lower sprocket 71, and the second lower sprocket 72 around which the first chain 1 and the second chain 2 are commonly wound are all double sprocket structures, so as to allow the first chain 1 and the second chain 2 to be wound.

[0044] See Figure 2 As shown in, the double sprocket structure means that the wheel body includes two sprockets for the chain to be wound.

[0045] In this embodiment, both the upper chain plate 3 and the lower chain plate 4 can be wound around the corresponding upper sprocket, reversing sprocket or lower sprocket. Specifically, see Figure 3As shown, the chain plate includes a chain side portion 31 and plate bodies 32. The number of plate bodies 32 is multiple, and all the plate bodies 32 are arranged at intervals along the length direction of the chain side portion 31. Both opposite sides of the plate bodies 32 are connected to the corresponding chain side portion 31. A traction block is fixed on the chain side portion 31, and the traction block is fixedly connected to the first chain 1 or the second chain 2.

[0046] The chain side portion 31 can be a structure such as a chain and should be bendable. Both opposite sides of the plate bodies 32 are fixed to the corresponding chain side portion 31. Since the entire chain plate includes multiple long strip-shaped plate bodies 32, adjacent plate bodies 32 are not fixed. Therefore, the entire chain plate can be wound. Specifically, see Figure 2 As shown, a roller 70 is also fixed on the driving shaft 7, and the roller 70 is used to support the winding of the chain plate.

[0047] The plate bodies 32 can be wound along with the roller 70. See Figure 1 As shown, the upper chain plate 3 descends along with the first chain 1 and the second chain 2 to the positions of the first reversing wheel 61 and the second reversing wheel 62. After the first chain 1 is reversed by the first reversing wheel 61 and the second chain 2 is reversed by the second reversing wheel 62, they move horizontally. When the first chain 1 and the second chain 2 are reversed by the first lower sprocket 71, the chain plate is wound accordingly, and the cakes on it are thrown onto the blanking belt conveying mechanism 200 during the winding process.

[0048] The side portion of the chain plate continues to move horizontally under the drive of the first chain 1 and the second chain 2. At this time, the upper chain plate 3 moves to the position of the lower chain plate 4 and becomes the new lower chain plate 4, and the original lower chain plate 4 rises along with the first chain 1 and the second chain 2 and becomes the new upper chain plate 3.

[0049] As an alternative implementation manner, see Figure 4 and Figure 5 As shown, the traction block includes a front-end traction block 8 and a rear-end traction block 9. The front-end traction block 8 fixedly connects the front end of the plate body 32 and the first chain 1, and the rear-end traction block 9 fixedly connects the rear end of the plate body 32 and the second chain 2; a relief groove 81 is provided on the front-end traction block 8, and the relief groove 81 is used for the second chain 2 to pass through, as Figure 2 shown.

[0050] The above structure of the chain plate, as Figure 2 shown, can enable the chain plate to move smoothly under the traction of the first chain 1 and the second chain 2.

[0051] The working process of the lifting and conveying mechanism in this embodiment is as follows:

[0052] See Figure 6As shown in the figure, the driving shaft 7 rotates counterclockwise driven by the motor, and the first chain 1 and the second chain 2 move driven by each sprocket. The belt of the feeding belt conveying mechanism 100 conveys the bare cakes 300 and throws the cakes to the upper layer of chain plates 3. Both sides of the upper layer of chain plates 3 are fixed on the first chain 1 and the second chain 2. The upper layer of chain plates 3 synchronously descends with the first chain 1 and the second chain 2. When reaching the positions of the first reversing wheel 61 and the second reversing wheel 62, the first chain 1 is reversed by the first reversing wheel 61 and the second chain 2 is reversed by the second reversing wheel 62 and then moves horizontally. When the first chain 1 and the second chain 2 are reversed by the first lower sprocket 71, the chain plates are wound accordingly, and the cakes on them are thrown to the discharging belt conveying mechanism 200 during the winding process. The bare cakes 300 are conveyed by the discharging belt conveying mechanism 200 to the next process.

[0053] See Figure 1 As shown in the figure, the side part of the chain plate continues to move horizontally driven by the first chain 1 and the second chain 2. At this time, the upper layer of chain plates 3 moves to the position of the lower layer of chain plates 4 and becomes the new lower layer of chain plates 4, and the original lower layer of chain plates 4 rises with the first chain 1 and the second chain 2 and becomes the new upper layer of chain plates 3. Thus, it circulates repeatedly, so as to realize continuous feeding, achieve uninterrupted production, and improve the production efficiency of biscuits.

[0056] The feeding belt conveying mechanism 100 includes a conveying belt.
