The discharged materials fall on the conveyor belt, and then the unsolidified candies are transported to the cooling room by the conveyor belt. The candies are cooled by the cold air blower in the cooling room to solidify the candies. Finally, the solidified candies are transported to the packaging machine, and the packaging machine is used to package the materials.

The cooled candy cans are cooled and shaped, and finally are packaged by a packaging machine.

[0004] In the above-mentioned related technologies, although the materials on the conveyor belt can be cooled by the air cooler, in order to increase the cooling time of the materials, a very long conveyor belt needs to be set up.

[0041] Reference Figures 1 to 3 A driving assembly (not shown in the figure) for connecting with the rotating roller is arranged on the frame 01. The driving assembly is used to drive the rotating roller to rotate, so as to rotate the first conveyor belt 11, the second conveyor belt 12 and the third conveyor belt 13.

[0043] Reference Figures 1 to 3 A buffer assembly 4 is provided between the first conveyor belt 11 and the second conveyor belt 12. The buffer assembly 4 is used to buffer the material falling from the first conveyor belt 11. The material falling on the buffer assembly 4 is then conveyed to the second conveyor belt 12, thereby preventing the material from being deformed when falling.

[0044] Reference Figures 1 to 3The buffer assembly 4 includes a mounting plate 41 fixed on the frame 01, a plurality of movable plates 42 slidably connected to the mounting plate 41, and a buffer conveyor belt 43 rotatably connected to the movable plate 42. The buffer conveyor belt 43 is wound on the mounting roller. A plurality of buffer conveyor belts 43 are provided, and the plurality of buffer conveyor belts 43 correspond to the plurality of movable plates 42 one by one. In this embodiment, three buffer conveyor belts 43 are provided, and a limit block 5 is fixedly installed on each movable plate 42. At the same time, a limit groove 51 for limiting the limit block 5 is provided on the mounting plate 41, and the limit block 5 is slidably connected in the limit groove 51. A control motor is provided on the mounting plate 41, and the control motor is connected to the mounting roller, and the buffer conveyor belt 43 is driven to rotate through the mounting roller, so that the material on the buffer conveyor belt 43 can be transported to the second conveyor belt 12.

[0045] Reference Figures 1 to 3 The limiting groove 51 includes a first sliding portion 511, a first connecting portion 512, a second sliding portion 513 and a second connecting portion 514. The first sliding portion 511, the first connecting portion 512, the second sliding portion 513 and the second connecting portion 514 are connected end to end, and the first sliding portion 511 is arranged above the second sliding portion 513. When the limiting block 5 is in the first sliding portion 511, the buffer conveyor belt 43 is below the first conveyor belt 11. At this time, the material on the first conveyor belt 11 falls onto the buffer conveyor belt 43; when the limiting block 5 is in the second sliding portion 513, the material on the buffer conveyor belt 43 can be transported to the second conveyor belt 12.

[0046] Reference Figures 1 to 3 , a first control assembly 2 and a second control assembly are arranged on the mounting plate 41, the first control assembly 2 is used to drive the limit block 5 to move in the first sliding part 511, and the second control assembly is used to drive the limit block 5 to move in the second sliding part 513; at the same time, a first pushing assembly 3 and a second pushing assembly are arranged on the mounting plate 41, the first pushing assembly 3 pushes the limit block 5 at the connection point between the first sliding part 511 and the first connecting part 512 to move to the connection point between the second sliding part 513 and the first connecting part 512, and the second pushing assembly pushes the limit block 5 at the connection point between the second connecting part 514 and the second sliding part 513 to move to the connection point between the first sliding part 511 and the second connecting part 514, and finally, the first control assembly 2 drives the limit block 5 at the connection point between the first sliding part 511 and the second connecting part 514 to move in the first sliding part 511. The structures and working principles of the first control assembly 2 and the second control assembly are the same, and in this embodiment, only the specific structure of the first control assembly 2 is described.

[0047] Reference Figures 2 to 5The first control component 2 includes a mounting roller rotatably connected to the mounting plate 41, a control conveyor belt 21 wound around the mounting roller, and a plurality of control panels 22 fixed on the control conveyor belt 21. The plurality of control panels 22 are arranged at intervals along the circumference of the control conveyor belt 21. The control panel 22 is used to abut against the limit block 5. At the same time, a control motor is arranged on the mounting plate 41. The control motor is used to connect with the mounting roller, thereby driving the mounting roller to rotate. When the mounting roller rotates, the control conveyor belt 21 and the control panel 22 are driven to rotate. Then the control panel 22 pushes the limit plate to move in the limit groove 51, so that the moving speed of the buffer conveyor belt 43 is the same as the rotation speed of the first conveyor belt 11, so that the material on the first conveyor belt 11 falls evenly onto the buffer conveyor belt 43. The control panel 22 on the second control assembly pushes the limit block 5 in the second sliding part 513 to move. At this time, the buffer conveyor belt 43 below will move along the length direction of the second sliding part 513, and the buffer conveyor belt 43 below will rotate at the same time, which makes it easier for the buffer conveyor belt 43 below to transport the material to the second conveyor belt 12.

[0048] In the initial state, two limit blocks 5 are provided in the first sliding part 511, and one limit block 5 is provided in the second sliding part 513, so that two buffer conveyor belts 43 are at the top and one buffer conveyor belt 43 is at the bottom, and the moving speed of the upper buffer conveyor belt 43 is the same as the rotation speed of the first conveyor belt 11. When the first conveyor belt 11 rotates, the control board 22 on the first control component 2 drives the two upper buffer conveyor belts 43 to move simultaneously, and at the same time, the control board 22 on the second control component drives the lower buffer conveyor belt 43 to move in the opposite direction, and the upper limit block 5 away from the molding component moves to the first sliding part. When the connecting part 511 and the first connecting part 512 are connected, the lower limit block 5 moves to the connecting part of the second sliding part 513 and the second connecting part 514, and then under the action of the first pushing component 3, the upper buffer conveyor belt 43 is pushed to move downward, and the second pushing component moves the lower buffer conveyor belt 43 upward. The buffer conveyor belt 43 moved to the bottom is loaded with materials, and then under the action of the control motor, the buffer conveyor belt 43 is driven to rotate. At this time, the materials will fall onto the second conveyor belt 12 and be transported by the second conveyor belt 12. Then the materials on the second conveyor belt 12 are transported to the third conveyor belt 13.

[0049] Reference Figures 1 to 5Under the action of the first control component 2, the second control component, the first pushing component 3 and the second pushing component, the three buffer conveyor belts 43 can be reciprocated along the direction of the limit groove 51, so that the buffer conveyor belt 43 with materials on the top can move to the bottom through the first connecting part 512, and the buffer conveyor belt 43 without materials on the bottom can move to the top through the second connecting part 514, and finally the materials falling from the first conveyor belt 11 can be buffered. Since the control board 22 is arranged on the control conveyor belt 21 at intervals, when the limit block 5 moves to the connecting part of the second connecting part 514 and the second sliding part 513, the control board 22 just abuts against the limit block 5, and when the limit block 5 moves to the connecting part of the first connecting part 512 and the second sliding part 513, the control board 22 also just abuts against the limit block 5, so that it is convenient to push the limit block 5 to move in the first sliding part 511 and the second sliding part 513.

[0050] Reference Figures 2 to 5 The first pushing assembly 3 includes a pushing block 31 slidably connected to the first connecting portion 512, a pushing frame 32 fixed on the pushing block 31, a pushing spring 33 fixed on the pushing frame 32, and a pushing rod 34 fixed on the limiting block 5. The pushing frame 32 is slidably connected to the mounting plate 41. One end of the pushing spring 33 away from the pushing frame 32 is fixed on the mounting plate 41, and is used to drive the pushing block 31 to move in a direction close to the second sliding portion 513, so that the end face of the pushing rod 34 abuts against the pushing frame 32.

[0051] Reference Figures 2 to 5 The pushing frame 32 includes a mounting portion 312 and an inclined portion 322, the mounting portion 312 and the inclined portion 322 are arranged at an angle, the mounting portion 312 is connected to the pushing block 31, and the pushing spring 33 is installed on the mounting portion 312, and the inclined portion 322 gradually inclines in a direction away from the mounting portion 312 toward a direction away from the limit block 5.

[0052] Reference Figures 2 to 5 When the limit block 5 slides in the first sliding portion 511, the pushing rod 34 will abut against the inclined portion 322, and then push the inclined portion 322 and the mounting portion 312 to move, so that the mounting portion 312 drives the pushing block 31 to move in the direction away from the second sliding portion 513, and the pushing spring 33 is gradually compressed. When the pushing rod 34 abuts against the mounting portion 312, the pushing block 31 is above the limit block 5, and then it is convenient for the pushing block 31 to abut against the limit block 5. When the limit block 5 corresponds to the first connecting portion 512, the pushing spring 33 drives the pushing block 31 to move, and the pushing block 31 drives the limit block 5 to move, so that the buffer conveyor belt 43 at the top moves to the bottom. At this time, the control motor drives the buffer conveyor belt 43 at the bottom to move, and then it is convenient for the material on the buffer conveyor belt 43 to move to the second conveyor belt 12.

[0053] In order to facilitate the lower limit block 5 to drive the push block 31 to move, a push rod 34 is fixed on both the upper and lower sides of each limit block 5, and the side of the push rod 34 close to the inclined portion 322 is set to an arc structure. In addition, the lower second push component and the upper first push component 3 are symmetrically arranged. The lower second push component is used to push the lower limit block 5 to move upward. Since the first push component 3 and the second push component have the same structure, the specific structure of the second push component is not repeated in this embodiment. In addition, a buffer component 4 is also provided between the second conveyor belt 12 and the third conveyor belt 13, so as to avoid deformation of the material falling on the third conveyor belt 13. Finally, the material transported by the third conveyor belt 13 is not easy to be deformed after being separated from the third conveyor belt 13 because the material has been cooled and the material is completely shaped.

[0054] The implementation principle of a material conveying device in an embodiment of the present application is as follows: the first conveyor belt 11 rotates, and the control panel 22 on the first control component 2 drives the two buffer conveyor belts 43 to move simultaneously, and at the same time, the control panel 22 on the second control component drives the lower buffer conveyor belt 43 to move in the opposite direction, and the material on the first conveyor belt 11 will fall onto the upper buffer conveyor belt 43, and finally the buffer conveyor belt 43 with the material will move downward and correspond to the second sliding part 513, and then, under the action of the control motor, drive the buffer conveyor belt 43 to rotate, and at this time the material will fall onto the second conveyor belt 12 and be transported by the second conveyor belt 12, and then the material on the second conveyor belt 12 will be transported to the third conveyor belt 13, thereby preventing the material from falling directly from the first conveyor belt 11 to the second conveyor belt 12, and reducing the deformation of the material when falling.

[0055] Embodiment 2:
