Description

Technical Field

[0001] The utility model particularly relates to a biscuit strip-forming and stacking machine. Background Art

[0002] After the biscuits are baked, they need to be sorted and packaged. The biscuits are placed in the feeding device of the packaging machine, and the biscuits are fed into the conveying device in batches according to a fixed number through the feeding device. The conveying device conveys the batches of biscuits to the packaging device in sequence. After the biscuits are packaged, they are finally made. In this process, the biscuits need to be sorted into strips and groups, which requires the use of a biscuit strip stacking machine, such as the biscuit strip sorting mechanism announced with the authorization announcement number CN207328916U. The biscuits on the temporary storage tray are pushed to the biscuit turning channel of the biscuit track plate by the push plate, and the horizontal biscuits are turned over to stand or tilt. Combined with the attached drawings, it can be seen that the biscuits must first be manually sorted into a stack and then placed on the temporary storage tray (the biscuits are stacked in the vertical direction). The manual sorting reduces the production efficiency and increases the production cost; in addition, for small or irregular biscuits, the difficulty of sorting increases. Since one end of the biscuits is generally flat and the other end is uneven, the push plate is prone to biscuits slipping when pushing the stacked biscuits. Utility Model Content

[0026] Furthermore, a photoelectric switch device 5 is provided on the conveying device. The biscuits 3 are conveyed to the photoelectric switch device 5. The photoelectric switch device 5 drives the four-cornered star wheel 43 to rotate through the servo motor 41 so that the gear teeth 431 on the four-cornered star wheel 43 flip the biscuits 3 during the rotation process.

[0027] Furthermore, a cantilever connecting plate 6 is rotatably provided on the base 1, the four-cornered star wheel 43 is provided on the cantilever connecting plate 6, a swing arm connecting plate 7 is hingedly provided on the cantilever connecting plate 6, and the swing arm connecting plate 7 is connected to an adjustment structure, and the adjustment structure is used to drive the swing arm connecting plate 7 to link the cantilever connecting plate 6 to adjust the position of the four-cornered star wheel 43 at the opening 2.

[0028] Furthermore, the adjustment structure includes a fisheye connecting rod 81 rotatably arranged on the swing arm connecting plate 7, and a screw sleeve 82 is connected to the fisheye connecting rod 81. A bearing seat fulcrum 83 is arranged on the base 1, and an adjusting screw 84 is connected to the bearing seat fulcrum 83. One end of the adjusting screw 84 is threadedly connected to the screw sleeve 82. Under the action of external force, the adjusting screw 84 is threadedly matched with the screw sleeve 82 to link the swing arm connecting plate 7.

[0029] Furthermore, the adjusting screw rod 84 is provided with an adjusting handle 841 at one end away from the swing arm connecting plate 7 .

[0030] Furthermore, the conveying device includes a first conveying channel 91 arranged to be inclined downward and a second conveying channel 92 arranged in a horizontal direction.

[0031] The working principle of the utility model is:

[0032] As Example 1, Figure 1The conveying device is used as an example to illustrate the design concept of the present application. Under the action of gravity, the biscuits slide down one by one along the first conveying channel 91 to the second conveying channel 92. In order to better explain the design principle of the present application, the biscuits conveyed in sequence along the conveying direction are defined as the first biscuit, the second biscuit, and the third biscuit. When the first biscuit slides to the photoelectric switch device 5, the photoelectric switch device 5 will drive the four-cornered star wheel 43 to rotate through the servo motor 41 when it detects the presence of the first biscuit. At this time, the first biscuit will continue to be conveyed to the four-cornered star wheel 43 located at the opening 2. When the gear 431 on the four-cornered star wheel 43 drives the first biscuit to rotate during the rotation process, the first biscuit is rotated to an inclined state. As the four-cornered star wheel 43 continues to rotate, the first biscuit continues to slide in the second conveying channel 92 under the push of the gear 431. However, since the first biscuit only has the bottom support of the second conveying channel 92, the first biscuit will appear to be lying flat in the second conveying channel 92; the conveying principle of the second biscuit is the same as above. Under the action of the four-cornered star wheel 43, it will also flip over to form an inclined state. When the second Under the push of the gear 431, the second biscuit will slide in the second conveying channel 92 (when the second biscuit slides in the second conveying channel 92, it will also push the first biscuit to slide forward), but because the first biscuit has a supporting function, the lower end of the second biscuit is abutted against the bottom of the second conveying channel 92, and the upper end of the second biscuit is abutted against the first biscuit, so the second biscuit can maintain an inclined state, and thus reciprocate, the third, fourth... can all be arranged one by one at an inclined angle along the conveying direction in the second conveying channel 92 (in this process, since the second conveying channel 92 has a limiting effect on the biscuits, when the biscuits are arranged one by one in the second conveying channel 92 in an inclined state, they can eventually present neatly combed biscuits arranged in strips). In the above technology, the rotation speed of the four-cornered star wheel 43 can be adjusted according to the conveying speed of the biscuits in the first conveying channel 91. When the photoelectric switch detection device detects the biscuits, the four-cornered star wheel 43 starts to rotate. As long as the biscuits slide onto the gear 431 during the rotation of the four-cornered star wheel 43, the gear 431 drives the biscuits to rotate during the rotation, thereby adjusting the tilt angle of the biscuits. As the four-cornered star wheel 43 continues to rotate, the biscuits are pushed to the second conveying channel 92. In the above technical solution, the flip mechanism can also be set on the first conveying channel 92.

[0033] The present application replaces the existing technology of manually stacking biscuits. The flipping mechanism of the present application can flip the biscuits one by one to an inclined state, and can automatically arrange the biscuits in strips; while reducing labor costs, it improves production efficiency; in addition, since the biscuits do not need to be manually stacked from a height, even small biscuits will not fall during the production process.

[0034] On the basis of the above technical solution, considering the flipping process of biscuits of different sizes, the present application sets the flipping mechanism as follows Figure 2 As shown, when the position of the four-corner star wheel 43 at the opening 2 needs to be adjusted, the adjusting handle 841 is rotated. At this time, the adjusting handle 841 drives the adjusting screw 84 to rotate. The adjusting screw 84 adjusts the length of the adjusting screw 84 in the screw sleeve 82 through the threaded fit of the screw sleeve 82. The screw sleeve 82 is connected to the fisheye connecting rod 81, so the fisheye connecting rod 81 can be pulled, and the fisheye connecting rod 81 drives the swing arm connecting plate 7 to swing, thereby driving the cantilever connecting plate 6 to rotate relative to the base 1. The four-corner star wheel 43 is set on the cantilever connecting plate 6, so it can drive the four-corner star wheel 43 to rotate, thereby changing the position of the four-corner star wheel 43 at the opening 2. As an embodiment 1, a servo motor 41 can be selected to drive the four-corner star wheel 43 to rotate, and a star wheel shaft 42 can be connected to the servo motor 41, and the star wheel shaft 42 is connected to the four-corner star wheel 43.
