Description

Technical Field

[0001] This application relates to the field of tobacco processing machinery technology, specifically to a small tobacco leaf feeding device for the rehydration process. Background Technology

[0002] In the rehumidification process of tobacco processing, small tobacco leaves are usually first screened by a vibrating screen and then conveyed into the rehumidification equipment for processing. To ensure the uniformity of rehumidification and the accuracy of product formulation, small tobacco leaves of different grades sometimes need to be blended, which places high demands on the stability and controllability of the feeding process.

[0003] Currently, this process is generally carried out manually, where operators use shovels to scoop the small tobacco leaves from the cardboard boxes and scatter them onto the conveyor belt. This method is not only labor-intensive and inefficient, but more importantly, manual scattering makes it difficult to accurately control the amount of material fed per unit time, which can easily lead to uneven distribution of the material on the conveyor belt. This, in turn, affects the accuracy of the subsequent blending ratio and the uniformity of rehydration, ultimately restricting the stability of product quality.

[0004] Therefore, this application proposes a small tobacco leaf feeding device for the re-moistening process, which can realize the automated and quantitative feeding of small tobacco leaves, ensuring the uniformity and controllability of material conveying from the source, so as to improve the overall processing quality of the re-moistening process. Utility Model Content

[0005] The main purpose of this application is to provide a small tobacco leaf feeding device for the rehydration process, which aims to solve the technical problems of low efficiency and difficulty in ensuring feeding uniformity caused by manual feeding in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A small tobacco leaf feeding device for a re-moistening process includes a support frame;

[0008] A vacuum feeder is mounted on the top of the front side wall of the support frame via a top seat. A connecting rod is mounted on the left side wall of the support frame. A discharge pipe is mounted on the front end wall of the connecting rod via a connecting seat. The right end of the discharge pipe is fixedly connected to the discharge end of the vacuum feeder.

[0009] The front side wall of the support frame and below the top seat is provided with a support rod, and the front side wall of the support rod is provided with a fixing seat;

[0010] The vacuum feeder has a feed pipe at its feed end, a connecting pipe at one end of the bottom wall of the feed pipe, a pipe connector at the other end of the connecting pipe, a circular plate with an interference fit on the outer wall of the pipe connector, a suction head on the top wall of the pipe connector, and an auxiliary suction mechanism on the outer wall of the circular plate.

[0011] As a further improvement of this application, the auxiliary suction mechanism includes a round rod, an extension rod is movably inserted into the round rod, and a threaded fixing seat is provided on the top wall of the extension rod.

[0012] As a further improvement of this application, the bottom of the inner wall of the round rod is provided with threads, and is threadedly matched with the threaded fixing seat.

[0013] As a further improvement to this application, the suction head adopts a duckbill-shaped structure.

[0014] As a further improvement of this application, the outer wall of the fixing seat is provided with a groove, and the length of the groove is greater than the diameter of the pipe connection seat.

[0015] The technical solution provided in this application may include the following beneficial effects:

[0016] This application, through the use of a vacuum feeder combined with a suction head, pipe connector, and support frame, overcomes the problems of cumbersome operation, high labor intensity, and low feeding efficiency associated with manual shovel feeding. It achieves automatic suction and conveying of small tobacco leaves, reducing manual labor and improving feeding continuity. Simultaneously, the stable suction and conveying control of the vacuum feeder ensures quantitative and uniform feeding of small tobacco leaves, avoiding fluctuations in feeding volume caused by manual tipping. This guarantees the re-blending effect and re-moistening quality of the small tobacco leaves during the re-moistening process, improving overall processing stability and product consistency.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] See Figure 1-2 As shown, a small tobacco leaf feeding device for the rehydration process includes a support frame 1. A vacuum feeder 3 is provided on the top of the front side wall of the support frame 1 through a top seat 2. A connecting rod 4 is provided on the left side wall of the support frame 1. A discharge pipe 6 is provided on the front end wall of the connecting rod 4 through a connecting seat 5. The right end of the discharge pipe 6 is fixedly connected to the discharge end of the vacuum feeder 3.

[0024] A support rod 7 is provided on the front side wall of the support frame 1 and below the top seat 2, and a fixing seat 8 is provided on the front side wall of the support rod 7;

[0025] The vacuum feeder 3 has a feed pipe 9 at its feed end, a connecting pipe 10 at one end of the bottom wall of the feed pipe 9, a pipe connector 11 at the other end of the connecting pipe 10, a circular plate 12 with an interference fit on the outer wall of the pipe connector 11, a suction head 13 on the top wall of the pipe connector 11, and an auxiliary suction mechanism on the outer wall of the circular plate 12.

[0026] Furthermore, the auxiliary suction mechanism includes a round rod 14, with an extension rod 15 movably inserted inside the round rod 14. A threaded fixing seat 16 is provided on the top wall of the extension rod 15. The round rod 14 can be telescopically moved to adjust its length. The extension rod 15 drives the threaded fixing seat 16 to the top of the round rod 14, and the threaded fixing seat 16 is tightened. By extending the length of the round rod 14 through the extension rod 15, the worker can hold the round rod 14 and move the suction head 13 to the bottom of the carton.

[0027] Furthermore, the bottom of the inner wall of the round rod 14 is provided with threads, and is threadedly matched with the threaded fixing seat 16. The extension rod 15 is moved to the top of the round rod 14, and the threaded fixing seat 16 is tightened to facilitate the fixing of the extension rod 15.

[0028] Furthermore, the suction head 13 adopts a duckbill-shaped structure. The worker holds the round rod 14 and moves the suction head 13 downward into the carton. After the vacuum feeder 3 is started, the suction head 13 sucks the small tobacco leaves in the carton into the pipe connector 11. The leaves are then transported into the vacuum feeder 3 through the connecting pipe 10 and the feed pipe 9, and then transported to the conveyor belt through the discharge pipe 6 for feeding.

[0029] Furthermore, the outer wall of the fixing seat 8 is provided with a groove, and the length of the groove is greater than the diameter of the pipe connector 11. The suction head 13 is set facing upwards, and the pipe connector 11 is inserted into the fixing seat 8. The pipe connector 11 is placed on the fixing seat 8 by the circular plate 12, thus completing the fixing of the suction head 13.

[0030] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0031] One specific application of this embodiment is:

[0032] In use, the device is securely installed on one side of the small tobacco leaf conveyor line in the re-moistening process using the support frame 1, ensuring that the left end of the discharge pipe 6 is precisely suspended above the conveyor line, providing an accurate landing point for subsequent material conveying. After the carton containing the small tobacco leaves is transported to the bottom of the vacuum feeder 3, the worker holds the round rod 14 and inserts the suction head 13 vertically downward into the inside of the carton. At this time, the vacuum feeder 3 is started, and its built-in negative pressure system quickly generates suction, forming a stable negative pressure area at the suction head 13. Using the principle of air pressure difference, the small tobacco leaves in the carton are quickly sucked into the pipe connection seat 11.

[0033] The small tobacco leaves are continuously conveyed into the vacuum feeder 3 for temporary storage through the sealed channel of the connecting pipe 10 and the feed pipe 9. Then, they are evenly conveyed to the conveyor belt below through the discharge pipe 6, completing the automated feeding operation. It is worth noting that the round rod 14 adopts a telescopic nested structure design. According to the depth of the carton, the worker can move the extension rod 15 along the axial direction of the round rod 14 to the top, and make the threaded fixing seat 16 tightly engage with the round rod 14 by rotating the threaded fixing seat 16. The position of the extension rod 15 is stabilized by the threaded fastening, thereby extending the overall length of the round rod 14. With the help of this structure, the worker does not need to bend over and can insert the suction head 13 into the bottom of the carton while standing. This effectively avoids the physical exhaustion and inconvenience caused by frequent bending over in traditional manual operation, and significantly improves the comfort and flexibility of the feeding operation.

[0034] After the feeding task is completed, flip the suction head 13 upward so that the pipe connector 11 can be accurately inserted into the positioning groove of the fixed seat 8. The round plate 12 and the top of the fixed seat 8 form a stable support structure, which can realize the quick positioning and storage of the suction head 13. This not only facilitates the daily management and maintenance of the equipment, but also effectively prevents the suction head from being accidentally bumped and damaged when idle, ensuring the service life and stability of the device.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
