Abstract
Description
Technical Field
[0001] This application relates to the field of testing equipment for candy production, and more specifically to a screening structure for empty candy packages. Background Technology
[0002] Candy is a food whose main ingredient is sugar. Currently, candy is packaged, stored, and transported, and candy is sealed in candy bags.
[0003] There is a candy packaging machine, such as Figure 1 As shown, the device includes a feeding tray 90, a conveyor belt 91, and a packaging device 92. The two ends of the conveyor belt 91 are connected to the feeding tray 90 and the packaging device 92, respectively. The conveyor belt 91 has multiple grooves 911. It should be noted that candy blocks are placed in the feeding tray 90 and are fed one by one to the end of the conveyor belt 91 near the feeding tray 90 through the spiral channel of the feeding tray 90. When a candy block falls from the output channel of the feeding tray 90 to the end of the conveyor belt 91 near the feeding tray 90, the candy block falls into the groove 911 and moves towards the packaging device 92 with the conveyor belt 91. Finally, the packaging device 92 packages the candy block in the groove 911. However, during the process of feeding the feeding tray 90 into the groove 911, there may be instances where candy pieces do not fall into the groove 911. In such cases, when the packaging device 92 seals the groove 911 where no candy has fallen in, an "empty bag" phenomenon will occur, meaning that there is no candy in the candy bag.
[0004] If empty candies are also included in the packaging process, customers will eventually find them during the purchase and consumption process, which will raise questions about the candy brand's quality control.
[0005] Therefore, there is a need for a candy empty package screening structure that can batch-screen empty candies. Summary of the Invention

[0028] Schematic diagram of empty candy packaging screening structure, for reference. Figures 2 to 3 According to a preferred embodiment of the present invention, a candy empty bag screening structure includes a material feeding bin 10 and a blower 20.
[0029] Specifically, the material discharge hopper 10 includes an inlet cavity 101, an air inlet cavity 102, an empty package outlet cavity 103, a free fall cavity 104, and a candy outlet cavity 105. The top of the free fall cavity 104 is connected to the inlet cavity 101, the bottom of the free fall cavity 104 is connected to the candy outlet cavity 105, and the two sides of the free fall cavity 104 are connected to the air inlet cavity 102 and the empty package outlet cavity 103, respectively. The air outlet of the blower 20 faces the air inlet cavity 102.
[0030] It should be noted that the sealed candy bag falls into the inlet 101 and, under the influence of gravity, falls along the inlet 101 into the free fall chamber 104. When the candy bag contains candy, its weight is relatively large, and the air blown by the fan 20 into the free fall chamber 104 cannot blow the candy bag towards the empty bag outlet 103. The candy bag containing candy falls into the candy outlet 105 under the influence of gravity and is discharged from the outside. When the candy bag does not contain candy, i.e., it is an "empty" candy bag, since the candy bag itself is made of plastic and is lightweight, when it falls into the free fall chamber 104, it will be blown by the fan 20 towards the empty bag outlet 103 and discharged from the empty bag outlet 103. This distinguishes between "empty" candy bags and candy bags that normally contain candy, and has the advantage of being able to screen out empty candies in batches.
[0031] Furthermore, in order to ensure that the sealed candy bags are orderly fed into the inlet cavity 101, the candy empty bag screening structure also includes a feeding device 30, one end of which is close to the inlet cavity 101.
[0032] Specifically, the feeding device 30 includes a first conveyor belt 301, a second conveyor belt 302, and a third conveyor belt 303. The second conveyor belt 302 is arranged at an angle, and one end of the first conveyor belt 301 is located above one end of the second conveyor belt 302. The other end of the second conveyor belt 302 is located above one end of the third conveyor belt 303 away from the inlet 101. The second conveyor belt 302 has a plurality of spaced support strips 3021 on its belt body.
[0033] It should be noted that the operator pours the candy bag to be inspected onto the first conveyor belt 301. As the first conveyor belt 301 moves, the candy bag is fed onto the support bar 3021 of the second conveyor belt 302, and moves along the second conveyor belt 302 toward the third conveyor belt 303. As the second conveyor belt 302 circulates to the back, the candy bag rolls from the support bar 3021 onto the third conveyor belt 303, moves along the third conveyor belt 303, and finally falls into the inlet cavity 101.
[0034] Furthermore, to facilitate the blowing of a candy bag without any candy inside into the empty package outlet 103, such as... Figure 3As shown, the top wall of the empty cavity 103 has a first expanding inclined surface 1031, and the bottom wall of the empty cavity 103 has a second expanding inclined surface 1032. By setting the first expanding inclined surface 1031 and the second expanding inclined surface 1032, the connection between the empty cavity 103 and the free-falling cavity 104 is arranged in an enlarged hole configuration. More specifically, in this embodiment, the slope of the second expanding inclined surface 1032 is less than the slope of the first expanding inclined surface 1031.
[0035] It should be noted that another function of setting the second expansion ramp 1032 is that when the wind force of the fan 20 is large, even if the candy bag containing the candy is blown towards the second expansion ramp 1032, because the low point of the second expansion ramp 1032 faces the free fall cavity 104, the candy bag containing the candy is not easily blown along the second expansion ramp 1032 into the deeper part of the empty bag outlet cavity 103, but is more likely to roll back to the free fall cavity 104 along the second expansion ramp 1032.
[0036] Furthermore, to prevent the empty candy wrapper from being blown towards the empty package outlet 103 by the wind, but instead slightly deviating and falling into the free fall cavity 104 after colliding with the connecting boundary between the empty package outlet 103 and the free fall cavity 104, the second expansion slope 1032 has an extension end 1033 at the end near the fan 20, and the extension end 1033 extends from the empty package outlet 103 into the free fall cavity 104.
[0037] It should be noted that by setting the extension end 1033, the possibility of the "empty" candy bag falling into the extension end 1033 and being blown deeper into the empty bag outlet 103 by the wind is increased.
[0038] Furthermore, to further reduce the probability that a candy bag containing candy will fall into the depth of the empty bag outlet 103 along the second expansion ramp 1032 when the wind force of the fan 20 is large, the end of the second expansion ramp 1032 facing away from the fan 20 has an arc-shaped protrusion 1034. It is worth mentioning that, since the "empty" candy bag is greatly affected by the wind force, it can overcome the obstacle set by the arc-shaped protrusion 1034.
[0039] Furthermore, to facilitate the discharge of air blown toward the empty package outlet 103 to the outside, the side wall of the empty package outlet 103 away from the fan 20 has a number of air outlet holes 1035.
[0040] Furthermore, the candy empty bag screening structure includes a discharge storage platform 40, which is located on the side of the discharge bin 10 away from the feeding device 30, and one end of the candy outlet 105 away from the free fall cavity 104 is located above the discharge storage platform 40.
[0041] It should be noted that the candy bags containing candy, tested by the wind force of the fan 20, fall into the candy outlet 105 under their own weight and roll down the cavity wall of the candy outlet 105 onto the discharge storage platform 40. Additionally, the empty bag outlet 103, located away from the free-fall cavity 104, is a vertical chamber with an open bottom, and a collection basket 50 is located below its opening. Empty candy bags blown into the empty bag outlet 103 fall downwards into the collection basket 50 under gravity.
[0042] In summary, the candy empty package screening structure described in the embodiments of this application has been clarified, which provides advantages such as the ability to screen out empty candies in batches.
[0043] It is worth mentioning that, in this embodiment, the candy empty package screening structure is simple in structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the candy empty package screening structure provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further beneficial to product promotion and use.
[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
