Description

Technical Field

[0001] This utility model relates to the field of filter rod detection technology, and in particular to an automatic rejection device for filter rod detection. Background Technology

[0002] Filter rod inspection and rejection is an important part of the tobacco production process. It is mainly used to ensure the quality and stability of filter rods. Through strict inspection and rejection, it is ensured that the filter rods entering the subsequent production stages meet the quality standards, thereby guaranteeing the overall quality of cigarette products. Unqualified filter rods are rejected in time to prevent them from entering the subsequent processing, reducing waste losses and rework costs caused by the use of unqualified filter rods.

[0003] A filter rod detection structure is disclosed in utility model application number 202322821193.4. By setting a detection device on the conveying structure, when there is a missing filter rod material segment after composite assembly loaded on the conveying drum, it is detected and marked. This effectively solves the problem that it is difficult to manually mark and remove the missing parts due to the high production speed, and greatly improves production efficiency and reduces product defect rate.

[0004] However, in the above-mentioned filter rod detection structure, the filter rods rotate end to end on the conveying drum, which can easily carry away qualified filter rods during rejection, resulting in insufficient rejection accuracy and easy waste of filter rods. In the above-mentioned filter rod detection structure, when the filter rods are adsorbed by the negative pressure adsorption holes, the curved shape of the filter rods cannot be fully adsorbed and limited. Therefore, this utility model proposes an automatic rejection device for filter rod detection to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide an automatic rejection device for filter rod inspection. This device uses an air pump to blow air through an air guide tube, and a solenoid valve controls the opening and closing of the air blowing. Compressed air is used to blow out unqualified filter rods through a waste pipe and into a waste bin, thus rejecting unqualified filter rods without affecting normal filter rods. A motor drives a rotating shaft to rotate multiple sets of conveyor rollers synchronously, enabling simultaneous inspection of multiple sets of filter rods and effectively improving inspection efficiency.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: an automatic rejection device for filter rod detection, comprising a detection platform, an airflow rejection mechanism, a rotary feeding mechanism, and a photoelectric detection mechanism.

[0009] Further improvements include: the motor output end is connected to the rotating shaft for drive, and the through hole corresponds to the positions of the air guide pipe and the waste pipe.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides an automatic rejection device for filter rod detection, including a detection platform 1, an airflow rejection mechanism, a rotary feeding mechanism, and a photoelectric detection mechanism. The airflow rejection mechanism includes a detection chamber 2, an air pump 3, an air guide pipe 4, a solenoid valve 5, a waste pipe 6, and a waste bin 7. The detection chamber 2 is fixedly located in the middle of the detection platform 1, and the air pump 3 is located below the detection platform 1. An air guide pipe 4 connects the air pump 3 and the detection chamber 2. Solenoid valves 5 are fixedly arranged on the air guide pipe 4. A waste pipe 6 is arranged and connected to the lower rear side of the detection chamber 2. A waste bin 7 is placed on the rear side of the detection platform 1. There is a waste bin 7, which corresponds vertically to the waste pipe 6. The air guide pipe 4 is connected to multiple branch points at the rear of the detection chamber 2. When a defective filter rod needs to be rejected, the air pump 3 starts and blows air into the filter rod in the limiting groove 11 through the air guide pipe 4. The filter rod is then discharged through the waste pipe 6 and falls into the waste bin 7. The air blowing is controlled by the opening and closing of the solenoid valve 5, which makes it easy to blow out and reject defective filter rods by gas. This solves the problem that insufficient rejection accuracy can easily lead to the waste of qualified filter rods. The detection chamber 2 is equipped with a rotating feeding mechanism, and a photoelectric detection mechanism is installed above the detection chamber 2.

[0020] The rotating feeding mechanism includes a rotating shaft 8, a motor 9, a conveying roller 10, a limiting groove 11, a limiting plate 12, a through hole 13, and a discharge chute 14. The rotating shaft 8 is rotatably mounted in the center of the detection chamber 2. The motor 9 is fixedly mounted on one side of the detection chamber 2. The conveying roller 10 is arranged and fixedly mounted on the rotating shaft 8. The limiting groove 11 is circumferentially formed on the conveying roller 10. Limiting plates 12 are fitted on both sides of the conveying roller 10 and are fixedly connected to the detection chamber 2. Through holes are circumferentially formed on the limiting plates 12. 13. The bottom of the detection chamber 2 is provided with a discharge trough 14. Photoelectric detection mechanisms are provided on both sides of the conveying roller 10. The output end of the motor 9 is connected to the rotating shaft 8. The through hole 13 corresponds to the position of the air guide pipe 4 and the waste pipe. When feeding, the filter rod is poured into the detection chamber 2 through the feed hopper 19. The motor 9 drives the rotating shaft 8 to rotate, which drives the conveying roller 10 to rotate synchronously. The filter rod is inserted into the limiting groove 11 in sequence to drive the filter rod to rotate. The limiting plate 12 limits the front and rear ends of the filter rod.

[0021] The photoelectric detection mechanism includes a bracket 15, a detection lamp 16, and a photoelectric sensor 17. The bracket 15 is fixedly arranged above the detection chamber 2. The detection lamp 16 is fixedly installed inside one side of the bracket 15, and the photoelectric sensor 17 is fixedly installed inside the other side of the bracket 15. The bracket 15 is positioned above both sides of the conveyor roller 10. A receiving box 18 is placed in the middle of the detection table 1. The receiving box 18 corresponds to the vertical position of the detection chamber 2. When detection is performed, the detection lamp 16 is turned on so that the light passes through the filter rod and is received by the photoelectric sensor 17. The intensity of the light received by the photoelectric sensor 17 determines whether the filter rod is qualified. Qualified filter rods fall into the receiving box 18 through the discharge chute 14 after rotating with the conveyor roller 10, completing the detection and rejection of defective products.

[0022] The testing chamber 2 is fixedly equipped with a feeding hopper 19, and a distribution plate 20 is fixedly arranged in an inclined manner inside the feeding hopper 19. The distribution plate 20 guides the filter rods, making it easy for the filter rods to be inserted into the limiting groove 11 in sequence.

[0023] The automatic rejection device for filter rod inspection pours the filter rods into the feed hopper and, guided by the distribution plate, sequentially enters the inspection chamber. A motor-driven shaft rotates, causing the conveyor rollers to rotate counter-clockwise. The filter rods, along with the conveyor rollers, are sequentially inserted into the limiting grooves and rotate synchronously. During inspection, an inspection light illuminates the rotating filter rods sequentially. A photoelectric sensor detects changes in brightness to determine if the filter rod is qualified. When a defective filter rod is encountered, an air pump starts, and the corresponding solenoid valve opens, blowing air through the air pipe to expel the defective filter rod through the waste pipe into the waste bin. When a filter rod is qualified, the solenoid valve closes to prevent air blowing, allowing the filter rod to fall into the receiving bin as it rotates with the conveyor rollers to the discharge chute. This process achieves both filter rod inspection and rejection.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
