Description

Technical Field

[0001] This utility model relates to the field of tobacco stem processing technology, specifically to a visual inspection and removal device for tobacco stem debris. Background Technology

[0002] Tobacco stems are a part of the stem of the tobacco plant, usually located at the base of the tobacco leaves. During tobacco processing, the stems are separated from the leaves for different uses. Tobacco stems can be processed for use in the manufacture of cigarettes, cigars, shredded tobacco, and other tobacco products. Through processes such as shredding and grinding, tobacco stems can increase the filling capacity of tobacco products and reduce costs.

[0003] Existing methods for removing debris from tobacco stems typically involve manual removal. However, manual removal requires workers to perform repetitive manual operations for extended periods, leading to physical exhaustion and fatigue. Furthermore, manual operations are prone to omissions or misjudgments, especially after prolonged work when attention decreases and the error rate increases. Therefore, a visual detection and removal device for tobacco stem debris is proposed. Utility Model Content

[0004] This utility model proposes a visual detection and removal device for tobacco stem debris, which solves the problem that in the existing related technologies, the debris in tobacco stems is usually removed manually. However, manual removal of debris requires workers to perform repetitive manual operations for a long time, which is physically demanding, easy to get tired, and prone to omissions or misjudgments. Especially after working for a long time, attention decreases and the error rate increases.

[0005] The technical solution of this utility model is as follows:

[0006] A visual inspection and removal device for tobacco stems and other debris includes: a conveyor and a controller;

[0007] A feed hopper is fixedly installed on one side of the top of the conveyor. Two rotating rods are rotatably connected to one side of the inner wall of the feed hopper. Multiple material feeding plates are fixedly installed on the outer walls of the two rotating rods. One end of the two rotating rods passes through the feed hopper and is fixedly connected to two synchronous pulleys. The two synchronous pulleys are tensioned and connected by a synchronous belt. A motor is fixedly installed on one side of the feed hopper. The output end of the motor is connected to one of the two synchronous pulleys.

[0008] An L-shaped plate is fixedly installed on the top of the conveyor. A vision module is provided on the inner top wall of the L-shaped plate. A cylinder is provided on the rear side of the conveyor. The output end of the cylinder extends into the conveyor and is fixedly connected to a push plate. The controller is electrically connected to the vision module and the cylinder respectively.

[0009] Preferably, two fixing plates are fixedly installed on one side of the inner wall of the L-shaped plate, and a lighting lamp is fixedly connected to one end of the two fixing plates.

[0010] Preferably, a through groove is provided on the front side of the conveyor, and a guide plate is fixedly installed on the inner wall of the through groove.

[0011] Preferably, a collection box is provided on the front side of the conveyor, and the collection box is located below the guide plate.

[0012] Preferably, four casters are fixedly installed at the bottom of the collection box, and the four casters are distributed at the four corners of the bottom of the collection box.

[0013] Preferably, a push rod is fixedly installed on one side of the collection box, and an anti-slip sleeve is provided on the outer side wall of the push rod.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In use, tobacco stems are placed inside the feed hopper, and then the conveyor is started to transport the tobacco stems. The motor is started, and the motor drives a synchronous pulley to rotate, which in turn drives a synchronous belt to rotate. At the same time, the synchronous belt drives another synchronous pulley to rotate, causing the material-pulling plate on the rotating rod to rotate inside the feed hopper. This causes the tobacco stems to fall intermittently onto the conveyor, making it easier for the vision module to detect the tobacco stems and remove impurities from them.

[0016] 2. When the conveyor transports the tobacco stems to the area below the L-shaped plate, the camera in the vision module takes a picture of the tobacco stems during transport and sends the information to the controller. The information is then detected and analyzed by remote equipment. When a pre-defined object is detected, the information is transmitted to the controller, which then activates a cylinder to push the pusher plate to remove the object. If the object is not a pre-defined object, the conveyor continues to transport the tobacco stems. This process removes the object from the tobacco stems without the need for manual removal, effectively preventing omissions or misjudgments and reducing the error rate. Attached Figure Description

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1 to 4 A visual detection and removal device for tobacco stems and debris includes: a conveyor 1 and a controller.

[0026] A feed hopper 2 is fixedly installed on one side of the top of the conveyor 1. Two rotating rods 3 are rotatably connected to one side of the inner wall of the feed hopper 2. Multiple material feeding plates 4 are fixedly installed on the outer walls of the two rotating rods 3. One end of the two rotating rods 3 passes through the feed hopper 2 and is fixedly connected to two synchronous pulleys 5. The two synchronous pulleys 5 are connected by a synchronous belt. A motor 6 is fixedly installed on one side of the feed hopper 2. The output end of the motor 6 is connected to one of the two synchronous pulleys 5.

[0027] An L-shaped plate 7 is fixedly installed on the top of the conveyor 1. A vision module 8 is provided on the inner top wall of the L-shaped plate 7. A cylinder 9 is provided on the rear side of the conveyor 1. The output end of the cylinder 9 extends into the conveyor 1 and is fixedly connected to a push plate 10. The controller is electrically connected to the vision module 8 and the cylinder 9 respectively.

[0028] In operation, tobacco stems are placed inside the feed hopper 2, and then conveyor 1 is started to transport the tobacco stems. Motor 6 is also started, driving a synchronous pulley 5 to rotate, which in turn drives a synchronous belt. Simultaneously, the synchronous belt drives another synchronous pulley 5 to rotate, causing the material-pushing plate 4 on the rotating rod 3 to rotate inside the feed hopper 2. This causes the tobacco stems to fall intermittently onto the conveyor 1, facilitating the detection and removal of impurities by the vision module 8. When the conveyor 1 transports the tobacco stems to below the L-shaped plate 7, the camera in the vision module 8 takes a picture of the transported tobacco stems and sends the information to the controller. The information is then analyzed by remote equipment. If a pre-defined impurity is detected, the information is transmitted to the controller, which activates cylinder 9 to push the pusher plate 10 to eject the impurity. If the impurity is not pre-defined, the conveyor 1 continues to transport the tobacco stems, thus achieving the purpose of removing impurities from the tobacco stems without manual removal. This effectively prevents omissions or misjudgments, reducing the error rate.

[0029] In this application, two fixing plates 11 are fixedly installed on one side of the inner wall of the L-shaped plate 7, and a lighting lamp 12 is fixedly connected to one end of the two fixing plates 11.

[0030] Specifically, the lighting lamp 12 is used to provide auxiliary lighting when the lighting conditions are poor, so that the vision module 8 can detect better.

[0031] In this application, a through groove 13 is provided on the front side of the conveyor 1, a guide plate 14 is fixedly installed on the inner wall of the through groove 13, and a collection box 15 is provided on the front side of the conveyor 1, with the collection box 15 located below the guide plate 14.

[0032] Specifically, when the debris is pushed out, it passes through the channel 13 and the guide plate 14 into the interior of the collection box 15 for collection.

[0033] In this application, four casters 16 are fixedly installed at the bottom of the collection box 15. The four casters 16 are distributed at the four corners of the bottom of the collection box 15. A push rod 17 is fixedly installed on one side of the collection box 15. An anti-slip sleeve 18 is fitted on the outer wall of the push rod 17.

[0034] Specifically, by holding the push rod 17, the collection box 15 is pushed, causing the casters 16 to rotate, which is used to move the collection box 15. At the same time, the anti-slip sleeve 18 on the push rod 17 is used to prevent slipping when holding the push rod 17.

[0035] Working principle of this utility model:

[0036] In operation, tobacco stems are placed inside the feed hopper 2, and then conveyor 1 is started to transport the tobacco stems. Motor 6 is also started, driving a synchronous pulley 5 to rotate, which in turn drives a synchronous belt. Simultaneously, the synchronous belt drives another synchronous pulley 5 to rotate, causing the material-pushing plate 4 on the rotating rod 3 to rotate inside the feed hopper 2. This causes the tobacco stems to fall intermittently onto the conveyor 1, facilitating the detection and removal of impurities by the vision module 8. When the conveyor 1 transports the tobacco stems to below the L-shaped plate 7, the camera in the vision module 8 takes a picture of the transported tobacco stems and sends the information to the controller. The information is then analyzed by remote equipment. If a pre-defined impurity is detected, the information is transmitted to the controller, which activates cylinder 9 to push the pusher plate 10 to eject the impurity. If the impurity is not pre-defined, the conveyor 1 continues to transport the tobacco stems, thus achieving the purpose of removing impurities from the tobacco stems without manual removal. This effectively prevents omissions or misjudgments, reducing the error rate.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
