In the field of food preparation industry, food machinery is needed to prepare food in batches. The finished product of sugar food is usually in block form. The sugar needs to be stirred and mixed, then pressed into sheets, divided into strips, and finally cut into blocks. In order to achieve sufficient mixing of the materials, high-temperature cooking is required when mixing the sugar, which makes the sheet-shaped sugar have a relatively high viscosity due to the high temperature. The material needs to be cooled and hardened by a cooling system during the molding process.

[0023] Combined with the drawings of the specification, the sheet material cooling system can be used in the field of food preparation to cool and harden sheet materials so that the sheet materials can adapt to the requirements of subsequent processing procedures. The cooling system is used to continuously process sheet materials, which are continuously prepared and formed by the upstream rolling process and continuously fed into the chassis.

[0024] The structure of the cooling system includes a chassis, Figure 1 The internal structure of the chassis is shown in FIG. The chassis is mainly supported by a frame-type rack 1. A box plate is also enclosed on the outside of the rack 1, so that the chassis forms a closed box body. The sheet material moves along a curved path in the chassis. The chassis is provided with an inlet 3 and an outlet 7 at both ends in the horizontal direction. The horizontal direction of the chassis mainly refers to the length direction of the chassis. The sheet material enters the chassis from the inlet 3 of the chassis and leaves the chassis from the outlet 7.

[0025] Several layers of conveyor belts 4 are arranged in the chassis. The conveyor belts 4 are generally mesh belts and have a closed loop structure. The conveyor belts 4 have at least two layers. As shown in the figure, the conveyor belts 4 have three layers. If the length of the chassis is long, the number of layers of the conveyor belts 4 can be shortened accordingly, otherwise the number of layers of the conveyor belts 4 can be increased. These conveyor belts 4 are arranged in parallel and spaced in the vertical direction. Between two adjacent layers of conveyor belts 4, there is a material guide structure between the discharge end of the upper conveyor belt 4 and the feed end of the lower conveyor belt 4. The material guide structure enables the material to enter the feed end of the lower conveyor belt 4 from the discharge end of the upper conveyor belt 4. Among these conveyor belts 4, the feed end of the uppermost conveyor belt 4 is located at the position of the inlet 3, and the discharge end of the lowermost conveyor belt 4 is located at the position of the outlet 7.

[0026] The conveyor belt 4 is connected to the power mechanism by transmission, and the power mechanism includes two transmission rollers, which are arranged in parallel at intervals, one of which is connected to the motor by transmission as an active part, and the other is a passive part. After the conveyor belt 4 is overlapped on the two transmission rollers, the lateral dimension of the conveyor belt 4 in the chassis is slightly smaller than the lateral dimension of the chassis. Driven by the transmission rollers, the conveyor belt 4 moves, and the materials on the conveyor belt 4 are cooled and moved forward in the chassis. By different motor setting positions, the movement directions of the conveyor belts 4 on the two adjacent layers of conveyor belts 4 are opposite to meet the continuous movement of the sheet materials. Since the sheet materials need to communicate with the outside, at the positions of the inlet 3 and the outlet 7 of the chassis, the feed end of the uppermost conveyor belt 4 can be extended to the outside of the chassis, and the discharge end of the lowermost conveyor belt 4 can be extended to the outside of the chassis from the position of the outlet 7 to meet this demand. It is also possible to set a two-belt conveyor device with opposite movement directions at the positions of the inlet 3 and the outlet 7 to realize the entry of materials into the chassis and the guidance of materials from the chassis to the outside.

[0027] A blowing device is also arranged in the chassis, and the blowing device includes a plurality of blowing structures, corresponding to each layer of the conveyor belt 4, and the blowing structures are arranged on the upper side of the conveyor belt 4. The blowing structure is provided with a blowing port 101, and the blowing structure is communicated with the air supply duct, and the blowing port 101 sends high-pressure air into the chassis to blow air inside the chassis. The air supply duct can be externally connected to a refrigerator, so that the air entering the chassis is kept at a low temperature. A transparent window is arranged on the top of the chassis, and the transparent window is long and extends along the length direction of the chassis. A "convex"-shaped shell-shaped air outlet structure 6 is arranged on the transparent window, and the air outlet structure 6 is buckled on the transparent window. After the blowing port 101 blows out high-pressure air, it drives the water vapor in the chassis and is discharged to the outside world from the air outlet structure 6.

[0028] As shown in the figure, the blowing structure includes a blowing pipe 10, which is arranged in the width direction of the conveyor belt 4, and a blowing port 101 is arranged on the wall of the blowing pipe 10. This blowing structure has a large blowing surface, which is compatible with the width of the conveyor belt 4. The blowing port 101 is strip-shaped, and the blowing ports 101 are arranged on opposite sides of the blowing pipe 10. The blowing ports 101 on both sides are located on the horizontal axis section of the blowing pipe 10, and the air outlet direction of the blowing port 101 is located in the horizontal direction. Each layer of the conveyor belt 4 is correspondingly provided with a plurality of blowing pipes 10, and these blowing pipes 10 are evenly spaced along the length direction of the conveyor belt 4.

[0029] The air supply duct includes a plurality of vertical pipes 5, which are arranged vertically. The lower end of the vertical pipe 5 is open, and the upper end is closed. The diameter of the vertical pipe 5 is larger than the diameter of the blowing pipe 10. One blowing pipe 10 is connected and bridged to two vertical pipes 5. Both ends of the blowing pipe 10 are respectively inserted into the vertical pipe 5. The two vertical pipes 5 are arranged on opposite sides of the conveyor belt 4. The height of the vertical pipe 5 is higher than the height of the uppermost conveyor belt 4. The number of blowing pipes 10 arranged on a pair of vertical pipes 5 is the same as the number of layers of the conveyor belt 4. One blowing pipe 10 is arranged on the upper side of one layer of the conveyor belt 4.

[0030] These risers 5 are arranged in two rows in the chassis, and the two rows of risers 5 are arranged on opposite sides of the conveyor belt 4. Two horizontal pipes 2 are respectively provided at the bottom of the chassis corresponding to the two rows of risers 5. The two horizontal pipes 2 are arranged at the two bottom corners of the chassis. The horizontal pipes 2 are arranged along the horizontal direction of the chassis, and a row of risers 5 is connected to one horizontal pipe 2. The horizontal pipe 2 is a hollow rectangular parallelepiped, and the risers 5 are usually inserted into the horizontal pipe 2. A connecting pipe 8 is provided at the middle position of the length of the two horizontal pipes 2. The connecting pipe 8 realizes the internal connection of the two horizontal pipes 2, so that an H-shaped structure is formed at the bottom of the chassis. An air inlet is provided on the horizontal pipe 2, and the air inlet is connected to the air compressor or air pump through a pipeline. The air inlet is located at the position of the connecting pipe 8. For ease of assembly, the blowing pipe 10 is detachably connected to the vertical pipe 5, and outward convex rings 11 are respectively provided at both ends of the blowing pipe 10; the vertical pipe 5 is detachably connected to the horizontal pipe 2, and an outward convex ring 11 is provided at the lower end of the vertical pipe 5. The airtightness requirements between the blowing pipe 10 and the vertical pipe 5, and between the vertical pipe 5 and the horizontal pipe 2 are not high.

[0031] A plurality of vertical shelves 9 are arranged in the chassis. The shelves 9 are sheet-shaped. The shelves 9 are provided with the same number of placement positions 91 as the number of layers of the conveyor belt 4. Two shelves 9 form a pair. The two shelves 9 are arranged on opposite sides of the conveyor belt 4. The lower end of the shelf 9 is generally welded and fixed on the horizontal pipe 2. A frame-type support frame can be arranged on the placement position 91. The conveyor belt 4 is slidably supported on the support frame, so that a large span setting of the conveyor belt 4 can be achieved. A rotatable intermediate roller can also be placed on the placement position 91. The conveyor belt 4 is slidably placed on the intermediate roller. The intermediate roller provides support for the conveyor belt 4.

[0032] In two adjacent layers of conveyor belts 4, the discharge end of the upper conveyor belt 4 and the feed end of the lower conveyor belt 4 are staggered in the transverse direction. The feed end of the lower conveyor belt 4 extends to the outside of the feed end of the upper conveyor belt 4, and the material continues to fall from the discharge end of the upper conveyor belt 4 to the feed end of the lower conveyor belt 4 under the action of gravity. In order to accommodate the sheet material entering and exiting the chassis, the feed end of the uppermost conveyor belt 4 extends from the inlet 3 of the chassis to the outside of the chassis, and the discharge end of the lowermost conveyor belt 4 extends from the outlet 7 of the chassis to the outside of the chassis.
