Description

Technical Field

[0001] The present invention relates to the technical field of food conveying devices, and in particular to a food conveying device for nutrition bars. Background Art

[0002] Nutrition bars are a type of bar-shaped or strip-shaped food made from a mixture of various grains, nuts and other ingredients. They are also called energy bars or protein bars. There are various types and flavors of nutrition bars, including nutrition bars that are simply made from a mixture of multiple ingredients, and nutrition bars that are coated with chocolate or cream. During processing, the processing steps are generally mixing, pressing and cutting into shape (or forming with a mold), coating and pouring (chocolate or cream), cooling and finally packaging, and each step requires a specific conveying device for transportation.

[0003] In the coating pouring process, the conveying device is generally a mesh belt conveyor. The pouring device is set above the mesh belt conveyor, and the nutrition bar passes under the pouring device via the mesh belt conveyor. During this process, the pouring device evenly pours the cream or melted chocolate, so that the coating medium adheres to the surface of the nutrition bar, and the remaining coating medium will seep through the mesh belt and flow into the receiving equipment below.

[0004] However, after the coating medium is poured onto the nutrition bar, it will flow from the nutrition bar to the mesh belt of the mesh belt conveyor and seep through the mesh belt and fall down. This causes the bottom of the nutrition bar to be unable to fully contact with the pouring liquid, which can easily lead to incomplete coating on the surface of the nutrition bar. Therefore, it is necessary to propose a conveying device that can be applied to the coating pouring equipment to enable the surface coating of the nutrition bar to be more comprehensive and complete. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a food conveying device for nutrition bars.

[0006] The present invention is implemented by the following technical solutions: a frame, the frame is provided with a conveyor belt composed of a plurality of crawler plate assemblies hingedly connected and capable of lifting the nutrition bar and driving the nutrition bar to swing, so that the bottom of the nutrition bar can be more fully in contact with the coating medium, the frame is also provided with two transmission wheels for driving the conveyor belt transmission, the crawler plate assembly includes a plate shell, both ends of the plate shell are rotatably installed with chain links connected to the frame for sliding, the chain links are hinged to each other to form a conveyor belt, the plate shell is provided with a top frame which can be lifted and lowered and the top of which can pass through the plate shell, Two hemispherical top blocks are fixedly installed at the bottom of the top frame, and pad rails are fixedly installed on the inner walls of both sides of the frame, so that when the track shoe assembly moves to the pad rails, the pad rails can lift the top frame through the hemispherical top blocks, and then the top frame lifts the nutrient bars placed on the plate shell, allowing the coating medium to flow through the bottom of the nutrient bars. A wavy guide groove is provided on the side wall edge of the pad rail, and a guide rod adapted to the wavy guide groove is fixedly installed on one side of the hemispherical top block, so that the wavy guide groove can control the guide rod to drive the track shoe assembly to swing when the track shoe assembly moves.

[0007] As a further improvement of the above solution, axles are fixedly installed at both ends of the plate shell, the axles pass through the chain links and are rotatably connected to the chain links, and the two transmission wheels are respectively engaged with the corresponding axles.

[0008] As a further improvement of the above solution, conveying rail grooves are provided on both sides of the frame, two guide shafts are fixedly installed on the chain links, the guide shafts extend into the conveying rail grooves and are slidably connected to the conveying rail grooves, and the wheel axles pass through the conveying rail grooves and are slidably connected to the conveying rail grooves.

[0009] As a further improvement of the above solution, the top frame is composed of a bottom plate slidably installed in the plate shell and a plurality of spacers fixedly installed on the top of the bottom plate.

[0010] As a further improvement of the above solution, the partition bar is a concave structure with high ends and low middle, so that after the nutrition bar is lifted up, it can limit the nutrition bar and prevent the nutrition bar from falling off the plate shell when swinging.

[0011] As a further improvement of the above scheme, the track plate assembly is also provided with a self-locking structure for controlling the plate shell to switch between limitation and flipping. The self-locking structure includes ear buckles fixedly installed at both ends of the top frame, and two chain links at both ends of the plate shell are provided with two limiting grooves that can cooperate with the ear buckles. In this way, when the top frame is not lifted up, the ear buckles cooperate with the limiting grooves to ensure the stability of the plate shell and prevent it from tilting by itself. When the top frame is lifted up, the ear buckles exit the limiting grooves to release the limitation on the plate shell, so that it can drive the nutrition bar to swing.

[0012] As a further improvement of the above solution, the ear clip is composed of a vertical bar and a limiting shaft fixedly arranged on the vertical bar, and the limiting shaft extends into the limiting groove and is slidably connected to the limiting groove.

[0013] As a further improvement of the above solution, mesh strips for arranging the nutrition bars are hinged on both sides of the plate shell, and a plurality of tooth rollers engaged with the conveyor belt and used to control the tilting of the mesh strips are rotatably installed in the frame, so that the messy nutrition bars can be pushed onto the plate shell.

[0014] As a further improvement of the above solution, two pairs of arc-shaped blocks are provided at both ends of the plate shell for controlling the tilting amplitude of the mesh strips, so as to avoid the mesh strips from being unable to reset normally due to excessive tilting angles.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] A track assembly is formed by structures such as a plate shell, chain links, a top frame, and a hemispherical top block, which can lift the nutrition bar and drive the nutrition bar to swing. These track assembly assemblies are combined into a conveyor belt, and with the upper pad rail, the conveyor belt can not only cooperate with the pouring device to realize the conveying and pouring of the nutrition bar, but also can lift the nutrition bar from the plate shell so that the poured coating medium can flow through the bottom of the nutrition bar, thereby solving the problem that the bottom of the nutrition bar is difficult to be covered by the coating medium. In addition, the nutrition bar can fully improve the pouring effect of the coating medium by swinging left and right during the pouring process, so that the coating medium can flow better to the bottom of the nutrition bar.

[0017] By setting up reversible mesh strips on both sides of the plate shell and setting up tooth rollers that can tilt the mesh strips, the nutrition bars that fall on the conveyor belt can be sorted so that they can be regularly deployed on the top of the plate shell, pre-paving the way for the subsequent lifting of the nutrition bars. At the same time, the mesh strips can also fill the gaps between the crawler shoe components without affecting the seepage of the coating medium.

[0018] By arranging limiting grooves on the chain links and arranging ear buckles composed of vertical bars and limiting shafts on the top frame that can cooperate with the limiting grooves, when the top frame is not lifted up, the ear buckles can limit the plate shell, so that the swingable plate shell can remain flat, allowing the nutrition bar to fall smoothly onto the plate shell; when the top frame is lifted up, the limitation on the plate shell can be released, so that the plate shell can meet the conditions for swinging left and right, thereby making the entire conveyor belt have the ability of adaptive adjustment.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Please combine Figures 1 to 15 A food conveying device for nutrition bars comprises a frame 1, a conveyor belt comprising a plurality of hinged track shoe assemblies, which is provided on the frame 1 and is capable of lifting the nutrition bars and driving the nutrition bars to swing, thereby allowing the bottom of the nutrition bars to more fully contact the coating medium. The frame 1 is also provided with two drive wheels 5 for driving the conveyor belt. Two side guards 25 are fixedly mounted on the frame 1 above the conveyor belt to limit the distribution range of the nutrition bars, thereby preventing the nutrition bars from falling onto the edge of the conveyor belt.

[0038] The track shoe assembly includes a plate shell 6, both ends of which are fixedly installed with wheel axles 8, and both ends of the plate shell 6 are rotatably installed with chain links 9 that are slidably connected to the frame 1. The wheel axles 8 pass through the chain links 9 and are rotatably connected to the chain links 9. The two transmission wheels 5 are respectively engaged with the corresponding wheel axles 8, and the chain links 9 are hinged to each other to form a conveyor belt. A top frame 11 that can be lifted and lowered and the top of which can pass through the plate shell 6 is provided in the plate shell 6. The top frame 11 is composed of a bottom plate slidably installed in the plate shell 6 and a plurality of partitions 12 fixedly installed on the top of the bottom plate. A plurality of slits 7 that are adapted to the partitions 12 are provided on the top of the plate shell 6. The partitions 12 can extend to the outside of the plate shell 6 through the slits 7 and lift up the nutrient bars. The partitions 12 are concave structures with high ends and low middle, so that when the nutrient bars are lifted up, the top frame 11 can be lifted and lowered. After the bar is lifted up, the nutrient bar can be restricted to prevent it from falling off the plate shell 6 during swinging. Two hemispherical top blocks 16 are fixedly installed at the bottom of the top frame 11, and pad rails 18 are fixedly provided on the inner walls of both sides of the frame 1, so that when the track shoe assembly moves to the pad rails 18, the pad rails 18 can lift the top frame 11 through the hemispherical top blocks 16, and then the top frame 11 lifts the nutrient bar placed on the plate shell 6, allowing the coating medium to flow through the bottom of the nutrient bar, and a wavy guide groove 181 is provided on the side wall edge of the pad rail 18, and a guide rod 17 adapted to the wavy guide groove 181 is fixedly installed on one side of the hemispherical top block 16, so that the wavy guide groove 181 can control the guide rod 17 to drive the track shoe assembly to swing when the track shoe assembly moves.

[0039] Through the above technical solution, the conveyor belt can not only cooperate with the pouring device to realize the conveying and pouring of the nutrition bar, but also can lift the nutrition bar from the plate shell 6 so that the poured coating medium can flow through the bottom of the nutrition bar, thereby solving the problem that the bottom of the nutrition bar is difficult to be covered by the coating medium. In addition, the nutrition bar can fully improve the pouring effect of the coating medium by swinging left and right during the pouring process, so that the coating medium can better flow into the bottom of the nutrition bar.

[0040] Combine Figures 3 to 7 , conveying rail grooves 3 are provided on both sides of the frame 1, two guide shafts 10 are fixedly installed on the chain link 9, the guide shafts 10 extend into the conveying rail groove 3 and are slidably connected to the conveying rail groove 3, and the wheel shaft 8 passes through the conveying rail groove 3 and is slidably connected to the conveying rail groove 3;

[0041] The side wall of the frame 1 is provided with a long opening and a guide plate 101 arranged in the long opening, and the gap between the two forms a conveying rail groove 3. In addition, a cover shell 2 fixedly connected to the guide plate 101 for maintaining the stability of the guide plate 101 is fixedly installed on the side wall of the frame 1. The cover shell 2 and the guide plate 101 are respectively provided with a positioning cylinder and a positioning shaft for alignment to ensure the stability between the two, and the two are fixed by bolts.

[0042] At the same time, the shaft of the transmission wheel 5 and the shaft of the gear roller 21 are both rotatably connected to the guide plate 101, and one end of the shaft of the transmission wheel 5 also passes through the corresponding cover shell 2 and extends to the outside of the cover shell 2;

[0043] A motor 4 for driving the transmission wheel 5 to rotate is fixedly installed in the frame 1. The motor 4 and the corresponding transmission wheel 5 are connected through a synchronous wheel and a synchronous belt. At the same time, the two transmission wheels 5 are also driven by a synchronous wheel and a synchronous belt.

[0044] Combine Figures 10 and 11 The track plate assembly is also provided with a self-locking structure for controlling the plate shell 6 to switch between limitation and flipping. The self-locking structure includes ear buckles 13 fixedly mounted on both ends of the top frame 11. The ear buckles 13 are composed of vertical bars and limiting shafts 14 fixedly arranged on the vertical bars. The limiting shaft 14 extends into the limiting groove 15 and is slidably connected with the limiting groove 15. Two limiting grooves 15 that can cooperate with the ear buckles 13 are provided on the two chain links 9 at both ends of the plate shell 6. In this way, when the top frame 11 is not lifted up, the ear buckles 13 cooperate with the limiting grooves 15 to ensure the stability of the plate shell 6 so that it will not tilt by itself. When the top frame 11 is lifted up, the ear buckles 13 exit the limiting grooves 15 to release the limitation on the plate shell 6, so that it can drive the nutrition bar to swing.

[0045] Through the above technical solution, when the top frame 11 is not lifted up, the ear buckle 13 can limit the plate shell 6, so that the swingable plate shell 6 can remain flat, allowing the nutrition bar to fall smoothly onto the plate shell 6. When the top frame 11 is lifted up, the restriction on the plate shell 6 can be released, so that the plate shell 6 can meet the conditions for swinging left and right, thereby enabling the entire conveyor belt to have the ability of adaptive adjustment.

[0046] Combine Figure 9 and Figure 14 , both sides of the plate shell 6 are hinged with mesh strips 19 for arranging the nutrition bars. The mesh strips 19 are composed of a plate body and a plurality of evenly distributed leaks arranged on the plate body, so as to ensure that the remaining coating medium can be filtered out more smoothly. A plurality of tooth rollers 21 that engage with the conveyor belt and are used to control the flipping of the mesh strips 19 are rotatably installed in the frame 1, so that the messy nutrition bars can be pushed onto the plate shell 6. Two pairs of arc-shaped blocks 20 for controlling the flipping amplitude of the mesh strips 19 are provided at both ends of the plate shell 6, so as to avoid the mesh strips 19 from flipping over too large an angle and being unable to reset normally.

[0047] Through the above technical solution, the nutrition bars that fall on the conveyor belt can be sorted so that they can be regularly deployed above the plate shell 6, pre-paving for the subsequent top frame 11 to lift the nutrition bars. At the same time, the mesh strips 19 can also fill the gaps between the track plate assemblies without affecting the seepage of the coating medium.

[0048] Combine Figures 4 and 5 The frame 1 is respectively provided with a first receiving hopper 22 located in the conveyor belt interlayer and a second receiving hopper 23 located under the conveyor belt. The first receiving hopper 22 and the second receiving hopper 23 are fixedly connected with the same conduit 24. The first receiving hopper 22 is in the coating pouring area, and the pad rail 18 is within the range of the first receiving hopper 22, so that the remaining coating medium can be received, and the second receiving hopper 23 is connected to the material box of the pouring device to recycle the received coating medium. Heaters are also provided on the first receiving hopper 22 and the second receiving hopper 23, so that the coating medium can be continuously heated to prevent the coating medium from cooling and solidifying.

[0049] The implementation principle of a food delivery device for a nutrition bar in the embodiment of the present application is as follows:

[0050] This device is mainly used in conjunction with the nutrition bar coating pouring device. The pouring device support plate is horizontally mounted above the device and aligned with the first receiving hopper 22 area, so that the poured medium can seep through the conveyor belt and fall into the first receiving hopper 22;

[0051] During use, the formed nutrition bars will be transported to the conveyor belt of this device by other conveying devices. When this device is in operation, the motor 4 drives the two transmission wheels 5 to rotate. When the two transmission wheels 5 rotate, they drive the entire conveyor belt to transport through the wheel shaft 8 on the crawler shoe assembly. In addition, the multiple tooth rollers 21 engaged with the conveyor belt will also rotate synchronously under the drive of the conveyor belt, and continuously lift the mesh strips 19 on the conveyor belt during the rotation process, so that the nutrition bars that fall in the area of the mesh strips 19 can be arranged on the plate shell 6.

[0052] Then, when the track plate assembly with the nutrition bar on the top moves to the pad rail 18 (pouring area), when the two hemispherical top blocks 16 at the bottom of the top frame 11 enter the pad rail 18, the entire top frame 11 rises and lifts the nutrition bar (the nutrition bar is lifted and limited by the partition bar 12, and the length of the partition bar 12 is slightly larger than the diameter and width of the nutrition bar, and the two are adapted to each other), and during the movement, under the guidance of the guide rod 17 and the wavy guide groove 181, the top frame 11 drives the plate shell 6 and the nutrition bar to swing left and right with the wheel axle 8 as the axis, so that not only the coating medium can be poured more evenly on the nutrition bar, but also the coating medium can flow through the bottom of the nutrition bar and cover the bottom of the nutrition bar. Then the remaining coating medium will be filtered out through the mesh bar 19 and fall into the first receiving hopper 22.

[0053] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
