Description

Technical Field

[0001] The utility model relates to the technical field of tobacco impurity removal, and more specifically to a tobacco foreign body detection device. Background Art

[0002] The silk-making process involves many process equipment and auxiliary equipment. Various debris can be found in the process, such as rubber, cardboard, hemp rope, etc. These debris may come from the impurities in the leaf group formula, the packaging materials are not cleaned up, the equipment falls off, or people accidentally drop them. Once mixed into the finished tobacco, it may affect the intrinsic quality and safety of the product. Things like belts, rubber, and metal sheets may damage certain components or parts of the rolling equipment, causing equipment safety hazards.

[0003] At present, after the tobacco leaf air selection process, chromatographic impurity removal equipment is used: the normal tobacco leaf and thin sheet colors are pre-set in the system's "color lookup table", so that the system can use the "color lookup table" to distinguish normal materials from foreign matter and remove foreign matter. However, the chromatographic impurity removal rate is ≥85%, and it is in the leaf processing section. The leaf shred processing section is not equipped with relevant equipment. In the actual production process, conveyor belts, side guard belts, plastic blocks, etc. can be found in the cigarette machine trough. Once they are wrapped in cigarettes, the cigarettes at the corresponding time end need to be treated with residual tobacco, that is, tobacco shreds are recycled, and operators are required to sort the recycled tobacco online to ensure the purity of the tobacco shreds.

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0023] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0024] according to Figure 1 As shown, the utility model provides a tobacco foreign body detection device, including a finished tobacco cabinet 1, a conveyor belt 2, an industrial camera 4, a rejection cylinder 6 and a controller;

[0025] The finished tobacco cabinet 1 is located at the starting end of the conveyor belt 2, and the industrial camera 4 is arranged above the middle of the conveyor belt 2 to collect pictures of the tobacco on the conveyor belt 2 and transmit the collected pictures to the controller;

[0026] The reject cylinder 6 is arranged on the transmission path of the conveyor belt 2 and is located on the rear side of the industrial camera 4. A push plate is provided at the output end of the reject cylinder 6, which is 6 mm away from the upper surface of the conveyor belt 2. When the controller identifies foreign matter, the controller can drive the reject cylinder 6 to start so as to remove the foreign matter from the conveyor belt 2.

[0027] The utility model identifies finished tobacco and removes obviously abnormal foreign matter, thereby reducing the debris flowing into the cigarette making machine process. The industrial camera 4 and controller used in the utility model are both existing technologies. The image acquisition card transmits the pictures collected by the industrial camera 4 to the controller, and the controller identifies foreign matter by color and volume. When the controller identifies foreign matter, the controller calculates the time from image acquisition to the removal port according to the frequency of the conveyor belt 2 motor, and the electromagnetic valve connects to the high-speed cylinder, and the push scraper pushes the defective tobacco mass out of the conveying channel, and then the electromagnetic valve is switched, and the cylinder returns to wait for the next cycle.

[0028] Furthermore, an arc plate 3 is fixed on the conveying path of the conveyor belt 2 by bolts. The arc plate 3 is located in front of the industrial camera 4, and the arc direction of the arc plate 3 is tangent to the conveying direction of the conveyor belt 2 to flatten the tobacco.

[0029] Furthermore, in order to improve the clarity of pictures taken by the industrial camera 4, the utility model also provides a light source generator 5 next to the industrial camera 4. The light source generator 5 is a strip light source, and its length is greater than or equal to the width of the conveyor belt 2 to ensure that the tobacco on the conveyor belt 2 is clear enough.

[0030] Furthermore, a waste cabinet 7 is provided on the conveying path of the conveyor belt 2. The waste cabinet 7 is located on one side of the push plate of the rejecting cylinder 6 and is used to collect the rejected foreign matter and tobacco.

[0031] Furthermore, baffles 8 are provided on both sides of the conveying path of the conveying belt 2, and the baffles 8 are located at the rear side of the rejecting cylinder 6. The baffles 8 are retracted toward the inner side of the conveying belt 2 to gather the scattered tobacco shreds.

[0032] In this embodiment, the baffle 8 is also bolted 250mm behind the push plate. Since the push plate of the rejection cylinder 6 needs to reject the tobacco containing foreign matter, it will inevitably disrupt some of the tobacco on the conveyor belt 2 during the pushing process. At this time, the tobacco on both sides is gathered toward the middle through the baffle 8 contracting in an eight-shaped shape and the continuous conveying of the conveyor belt 2.

[0033] Furthermore, a metering tube 9 is provided at the rear end of the conveyor belt 2, and the metering tube 9 is used to receive and meter the shredded tobacco.

[0034] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
