Description

Technical Field

[0001] This invention relates to the field of bottle cap conveying equipment technology, and in particular to the discharge mechanism of a disc-type cap sorting machine. Background Technology

[0002] To achieve large-scale automated production, high speed and stability of bottle cap material flow are required. Bottle cap sorting machines are typically used to organize randomly arranged round bottle caps so that the openings face the same direction and are output sequentially to meet the requirements of subsequent production or filling equipment. However, existing bottle cap sorting equipment has a complex structure; the posture adjustment slides must be strictly matched to the corresponding bottle cap specifications, making it incompatible with multiple bottle cap sizes. Changing bottle caps requires changing the corresponding sorting mechanism, resulting in low equipment utilization. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the main objective of this invention is to provide a simple and efficient discharge mechanism for a disc-type cap sorting machine.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a discharge mechanism for a disc-type cap feeder, comprising a cap feed channel, wherein a plurality of feeding nozzles are provided on the cap feed channel to blow caps along the cap feed channel, a return pipe is provided below the cap feed channel, and a notch is provided above the return pipe in the cap feed channel, wherein a tongue is provided at the notch, and when the cap opening is facing upward, the cap passes normally through the cap feed channel along the tongue; when the cap opening is facing downward, the cap falls obliquely along the tongue into the return pipe below, wherein a plurality of return nozzles are provided on the return pipe.

[0005] Preferably, an air booster nozzle is provided on the bottle cap feed channel above the gap between the tongue and the notch.

[0006] Preferably, a counter is provided at the tail end of the bottle cap feed channel.

[0007] Preferably, a limiting plate is provided at the top of the bottle cap feed channel.

[0008] This invention has the following advantages over existing technologies. Its core principle is to automatically sort bottle caps by utilizing the cooperation of a tongue and a notch: bottle caps with the opening facing upwards slide normally along the tongue and are output; bottle caps with the opening facing downwards fall obliquely from the tongue into the return pipe, and are then circulated through the return pipe via a return air nozzle. The advantages are: 1. Simplified structure and strong compatibility: It eliminates the need for traditional vibratory feeders and customized slides, combining centrifugal rotation with pneumatic conveying to adapt to various bottle cap specifications without replacing parts. The diameter of the bottle cap does not need to be exactly the same as the internal width of the bottle cap channel; it only requires that the bottle cap with the opening facing downwards can fall as it passes the tongue. 2. Highly efficient sorting: The mechanical sorting by the tongue, combined with the booster air nozzle accelerating the forward sliding of the bottle caps and the automatic return air nozzle, improves output efficiency and continuity.

[0011] The invention will now be further described with reference to the accompanying drawings.

[0012] like Figure 1 As shown, the discharge mechanism of a disc-type cap feeding machine includes a cap feeding channel 1. The cap feeding channel 1 is provided with a plurality of feeding air nozzles 2 that blow caps to slide along the cap feeding channel 1. A return pipe 3 is provided below the cap feeding channel 1. The cap feeding channel 1 is provided with a notch 4 above the return pipe 3. A tongue 5 is provided at the notch 4. When the cap opening is facing upward, the cap passes normally through the cap feeding channel 1 along the tongue 5. When the cap opening is facing downward, the cap falls obliquely along the tongue 5 into the return pipe 3. The return pipe 3 is provided with a plurality of return air nozzles 6.

[0013] This solution presents a discharge mechanism for a disc-type cap sorting machine. Its core principle is to automatically sort bottle caps based on the interaction of a tongue 5 and a notch 4: caps with upward-facing openings slide normally along the tongue 5 for output; caps with downward-facing openings fall obliquely from the tongue 5 into the return pipe 3, and are then circulated through a return air nozzle 6 to the return box. The advantages are: 1. Simplified structure and strong compatibility: eliminating the need for traditional vibratory feeders and customized tracks, it combines centrifugal rotation with pneumatic conveying to adapt to various cap sizes without requiring component replacement. The diameter of the caps does not need to be exactly the same as the internal width of the cap channel 1; only caps with downward-facing openings need to fall as they pass the tongue 5. 2. Highly efficient sorting: the mechanical screening by the tongue 5, combined with the booster air nozzle 7 accelerating the forward sliding of the caps and the automatic return air nozzle 6, improves output efficiency and continuity. The tongue 5 is right-angled, facilitating connection and replacement with bolts at the notch 4.

[0014] Preferably, a booster nozzle 7 is provided on the bottle cap feed channel 1 above the gap between the tongue 5 and the notch 4. The booster nozzle 7 can increase the speed at which the bottle cap falls into the return pipe 3, thereby increasing the conveying speed.

[0015] Preferably, a counter 8 is provided at the tail end of the bottle cap feeding channel 1. The counter 8 facilitates the counting of bottle caps.

[0016] Preferably, a limiting plate 9 is provided at the top of the bottle cap feeding channel 1. The limiting plate 9 can confine the bottle cap inside the bottle cap feeding channel 1 and prevent it from being squeezed out.

[0017] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
