Description

Technical Field

[0001] The present invention relates to the technical field of chocolate production equipment, and in particular to a three-dimensional transmission device for chocolate production. Background Art

[0002] A chocolate production line is a system of machines and equipment that processes the raw materials of chocolate (such as cocoa beans, sugar, milk, etc.) into the final product. The design of the production line usually includes multiple links to ensure that the production of chocolate is efficient, stable and meets quality standards. Raw materials such as cocoa beans, sugar, milk, etc. first need to go through processing steps such as washing, grinding and crushing. Cocoa beans need to be roasted, shelled and ground to extract cocoa liquor. Different raw materials (such as sugar, milk, cocoa liquor, emulsifiers, etc.) are mixed together according to the recipe to ensure uniform ingredients. This process is usually carried out under heating conditions to make the chocolate smoother. After mixing, the chocolate slurry needs to go through a refining process to reduce the size of the particles, improve the fineness of the chocolate, and make the taste smoother. The chocolate needs to go through a tempering process to ensure that its crystal structure is stable, the surface is smooth, and it has a good taste and appearance. Tempering usually includes multiple heating and cooling. The tempered chocolate slurry is fed into a molding machine and formed into chocolate products of different shapes, such as chocolate blocks, chocolate bars, chocolate hearts, etc. through molds. After molding, the chocolate is cooled and solidified. Modern chocolate production lines usually use highly automated equipment, which can greatly improve production efficiency and reduce manual operations.

[0003] However, existing chocolate production often encounters the following problems: traditional chocolate production lines have bottlenecks in space utilization and material transportation efficiency, resulting in slow production speeds and a large footprint. Production equipment and conveyor belts occupy too much ground space, limiting the layout and expansion of the production line. If adjustments or expansions are required, most of the production processes or equipment may need to be redesigned, which is costly and time-consuming. Summary of the invention

The present invention uses the mutual cooperation of the ascending transport mechanism and the descending transport mechanism, and the three-dimensional lifting device can automatically lift or lower the chocolate from one position to another position, and then push the independent conveyor belt filled with chocolate between the ascending transport mechanism and the descending transport mechanism through the conveying cylinder, thereby completing the lifting cycle in the three-dimensional space and fully releasing the ground space.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1-5 As shown, the present invention provides a three-dimensional transmission device for chocolate production, and the three-dimensional conveyor includes a bracket 1, a slide rail 2, an independent conveyor belt 3, a three-dimensional lifting device 4, and a conveying cylinder 5. Two groups of slide rails 2 are provided, and the two groups of slide rails 2 are laid side by side on the bottom frame legs of the bracket 1. The slide rails 2 and the conveyor belt constitute the basic structure of the entire transmission system. By setting the slide rails 2, the stable operation of the conveyor belt in all directions can be ensured. At the same time, the conveyor belt system improves the transmission efficiency and distribution capacity of the material by setting multiple groups of conveyor belts side by side. Two groups of independent conveyor belts 3 are provided, and each group of independent conveyor belts 3 is composed of multiple conveyor belts arranged longitudinally side by side. The three-dimensional lifting device 4 includes an ascending transport mechanism 41 and a descending transport mechanism 42, and the ascending transport mechanism 41 and the descending transport mechanism 42 are installed side by side on the bracket 1. The composition structure of the ascending transport mechanism 41 and the descending transport mechanism 42 is the same, and the ascending transport mechanism 41 and the descending transport mechanism 42 correspond to the two groups of independent conveyor belts 3 one by one. The lifting device includes an ascending and descending transport mechanism 42, the purpose of which is to ensure that the chocolate can be transported at different heights in the production line to avoid cross interference and improve the space utilization efficiency of the production line.

[0043] There are two groups of conveying cylinders 5, which are respectively located at the upper and lower sides of the three-dimensional lifting device 4. The output ends of the two groups of conveying cylinders 5 are output in opposite directions. The output end of the conveying cylinder 5 at the top of the independent conveyor belt 3 contacts the top independent conveyor belt 3, and the output end of the conveying cylinder 5 at the bottom of the independent conveyor belt 3 contacts the bottom independent conveyor belt 3. The roller of the bottom independent conveyor belt 3 is slidably connected to the slide rail 2. The cylinder acts as a driving force to control the docking of the conveyor belt with other equipment during the lifting process to ensure a smooth transition during the transmission process. The retraction and output end adjustment mechanism of the cylinder can accurately control the movement of the conveyor belt to avoid collision or unstable transportation.

When the screw rod 34 is twisted, one end of the screw rod 34 will push the roller connected to it through the bayonet 35, pull the gap between the two rollers 31, so as to adjust the tension of the conveyor belt 32. The independent conveyor belt 3 adjusts the tension of the conveyor belt through the tensioning frame and the tensioning screw 34, thereby ensuring that the conveyor belt can maintain the best tension under different working environments to avoid slippage or excessive stretching of the conveyor belt during transmission. The screw 34 and the tensioning frame can be made of corrosion-resistant alloy steel or engineering plastics to improve durability.

The rotating shaft rod 411 sleeved at the other end of the linkage chain 416 is parallel to the rotating shaft rod 411 installed on the driving gear 414, and multiple driving plates 417 are installed side by side and in parallel on the transmission chain 412, and the driving plates close to the independent conveyor belt 3 are in contact with the tensioning frame.

When multiple driving plates 417 are driven by the chain to start circulating operation, some driving plates in contact with the tensioning frame will push down the corresponding independent conveyor belts 3 one by one through the tensioning frame, and the output end of the conveying cylinder 5 at the bottom retracts, and its output end pushes the bottom independent conveyor belt 3 toward the ascending conveying mechanism 41. Then, the conveyor belt will be lifted by the ascending conveying mechanism 41 to complete the cycle.
