Technical Field

[0001] The present application relates to the technical field of strip food feeding equipment, and in particular to a feeding mechanism for a strip food filling machine. Background Art

[0002] Bar food filling is a processing method that fills food into packaging containers in the form of bars. This method is usually used to produce bar foods. This filling method is usually suitable for automated production lines, which can improve production efficiency and product quality.

[0003] Since strip food is in the shape of a long strip, it needs to be inserted into the can upside down during filling. Before filling, a feeding counting and sorting mechanism is required. Among the feeding counting mechanisms, according to traditional mechanisms of this type, most of them are conveyed by conveyor belts and counted by multiple electric eyes. Because the strip food packaging bags are in a mess when they are conveyed, there is no pattern. Therefore, when counting at the end, multiple electric eyes, multiple algorithms and multiple processes are required to accurately calculate the specific number, which will increase the cost of the machine.

[0004] According to the above problem description, a feeding mechanism for a strip food filling machine is proposed, which can straighten the strip food being fed, thereby reducing the cost increased by the electric eye counting algorithm. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] See also Figure 1-4 In this embodiment, a feeding mechanism of a strip food filling machine includes a conveying device for transmission and a straightening device for proportioning ingredients, wherein the straightening device is located at the upper part of one end of the conveying device and completes the uniform distribution of the strip food by dropping the ingredients.

[0027] Furthermore, the conveying device includes a machine base 1 and a chain feeding structure located in the machine base 1 .

[0028] Preferably, the straightening device includes a batching bin 2 located above the machine base 1 and a conveying device 3 connected to the batching bin 2 .

[0029] Specifically, the conveying device 3 uses a pulley conveyor belt to transport the strip foods from the conveying device 3 to the ingredient bin 2.

[0030] Preferably, the batching bin 2 specifically includes an installation bin 21 and a limiting bin 22 integrally connected to the installation bin 21 , and the lower end of the limiting bin 22 transitions into an arc shape toward the bottom of the installation bin 21 .

[0031] With this design, the cross-sections of the upper and lower ends of the limiting bin 22 are both rectangular, but the diameter of the transition from the upper end to the lower end of the limiting bin 22 can be gradually shortened, so that the strip food that drops onto the machine base 1 through the ingredient bin 2 can avoid being arranged in a messy manner, and the direction of the strip food can be roughly consistent.

[0032] In addition, in actual production and use, it is necessary to adjust the distance between the ingredient bin 2 and the upper surface of the machine base 1 according to the size of the strip food, on the one hand to reduce the damage to the strip food caused by high-altitude delivery, and on the other hand to reduce the disorder caused by the strip food falling from a high altitude.

[0033] In this embodiment, a delivery opening 23 is formed through the outer wall of the installation bin 21 , and one end of the conveying device 3 extends to the delivery opening 23 , so that the conveyed food can directly fall into the limiting bin 22 .

[0034] In this embodiment, the chain feeding structure includes a driving member, a chain 7 connected to the driving member, and a positioning column 8, wherein the positioning column 8 is trapezoidal in shape, and an extension groove 9 is provided on the upper surface of the machine base 1. By passing through the extension groove 9, the positioning column 8 can extend to the surface of the machine base 1 and complete the transmission along with the chain 7.

[0035] In this embodiment, the driving member includes a motor 5 fixed in the machine base 1 and a sprocket 6 fixedly connected to the power end of the motor 5 , two sprockets 6 form a group, and a chain 7 is meshed on the outside of the two sprockets 6 .

[0036] In a specific implementation, the trapezoidal lower end of the locking post 8 and a single chain shaft of the sprocket 6 are connected to each other, so that the locking post 8 moves along the direction of the extension slot 9 under the traction of the motor 5 .

[0037] Preferably, the chain feeding structure includes two groups symmetrically arranged on the machine base 1.

[0038] With this design, the four symmetrical positioning posts 8, i.e., the two positioning posts 8 on the single chain 7 symmetrical on both sides, can provide a limiting space for the long strip of food, so that it can be transported in a direction perpendicular to the chain 7, thereby reducing the difficulty of counting.

[0039] It should be noted that a limit fence 10 located outside the extension groove 9 is fixedly installed on the top of the base 1. The limit fence 10 includes two limit fences. Under the obstruction of the two limit fences 10, the positions of the two ends of the strip food can be restricted so that it can be maintained in the position between the positioning columns 8 for transportation.

[0040] The base 1 in this embodiment is also provided with an anti-fall structure, which includes a mounting frame 14 fixedly mounted on the outer side of the base 1 , a connecting pin 16 located on the mounting frame 14 , and a limiting rod 17 fixedly connected to the connecting pin 16 .

[0041] Furthermore, the mounting frame 14 is L-shaped and extends to the top of the machine base 1 . A slide groove 15 is provided on the upper surface of the mounting frame 14 , and a connecting pin 16 is slidably connected to the slide groove 15 .

[0042] By sliding the connecting pin 16 relative to the slide slot 15, the limiting rod 17 connected to the connecting pin 16 can be movably adjusted relative to the machine base 1. At the same time, a locking nut is threadedly installed on the outside of the connecting pin 16 to limit the position of the connecting pin 16 relative to the mounting frame 14 after adjustment.

[0043] Preferably, the limiting rod 17 is suspended above the machine base 1 in a Y shape, and the limiting rod 17 can slide up and down relative to the connecting pin 16 to adjust the height, so as to prevent the strip food bag from falling after the material is dropped by the straightening device.

[0044] In this embodiment, a collecting bin 11 is fixedly mounted on one end of the base 1, a door panel 12 is arranged inside the collecting bin 11, and a cylinder 13 connected to the door panel 12 is fixedly mounted outside the collecting bin 11, and the cylinder 13 is used to control the opening of the door panel 12.

[0045] In addition, an electric control box 4 is fixedly mounted on one side of the base 1 for controlling the operation of equipment on the base 1 .

[0046] In the specific implementation, the structures of the door panel 12, the cylinder 13 and the collecting bin 11 are all conventional strip food feeding equipment. An electric eye 18 is installed at the end position where the base 1 transitions to the collecting bin 11 for counting. When the count reaches 10 or 20, the door panel 12 is pulled open by the cylinder 13, so that the quantitative feeding of the strip food can be completed. Then the cylinder 13 controls the door panel 12 to close again, and the above feeding process is repeated.

[0047] The working principle of the above embodiment is:

[0048] The strip food is uniformly fed into the batching bin 2 through the conveying device 3, and the strip food in the batching bin 2 is adjusted to fall in a direction through the narrow opening of the batching bin 2. At this time, the strip food falls into the accommodation space between the four positioning columns 8 on the surface of the machine base 1. The positioning columns 8 rotate with the chain, and the positioning columns 8 move with the strip food toward the collecting bin 11. During the displacement process, they are limited by the upper end of the limiting rod 17, so that the strip food is not easy to fall to the outside of the machine base 1. At this time, the sprocket 6 pulled by the motor 5 drives the chain 7 to convey, and the positioning columns 8 fixed on the chain 7 move along the extension groove 9 to realize the strip food. The strip food is conveyed, and the counting judgment is completed after the electric eye 18 at the end of the machine base 1 is passed. When the count meets the set value, the cylinder 13 is controlled by the electric control box 4 to drive the door panel 12 to open, and the strip food falling into the collection bin 11 falls uniformly to complete the feeding process. The strip food after falling enters the next round of canning process, and then the door panel 12 is controlled to close by the cylinder 13, and the feeding mechanism enters the next feeding cycle. The motor driving the sprocket to rotate in the feeding mechanism and the conveyor belt or conveying equipment of the straightening device are all controlled by the main control board. Such synchronization will not cause the strip food to accumulate in a certain link.

[0049] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
