Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing technology, and in particular to a raw material screening device for tobacco processing. Background Technology
[0002] A raw material screening device for tobacco processing is a device specifically designed for screening raw materials such as tobacco leaves and stems during the tobacco processing process.
[0003] Existing tobacco raw material screening devices directly use screening plates to screen tobacco raw materials. However, since there are many types of impurities inside tobacco raw materials after cutting, the effect of directly using screening plates to screen is limited, resulting in a decrease in the screening quality of tobacco raw materials.
[0004] An existing patent (publication number: CN222152909U) discloses a raw material screening device for tobacco processing. Its technical solution includes an air classifier and a screening box. A screening box is installed at the bottom of the air classifier via damping rubber. A waste trough is installed on one side of the bottom of the air classifier via a partition. A main material trough is installed at the bottom of the air classifier near the waste trough. The bottom of the main material trough is connected to the top of the screening box via a discharge pipe. A fine material trough is installed at the bottom of the air classifier near the main material trough. An air classifier cylinder is installed inside the air classifier at the top of the waste trough. This raw material screening device for tobacco processing solves the problem that existing tobacco raw material screening devices directly use screening plates to screen tobacco raw materials. Because tobacco raw materials contain many types of impurities after cutting, direct screening using screening plates has limited effectiveness, leading to reduced screening quality. This device reduces internal impurities in tobacco raw materials, thereby ensuring the screening quality of tobacco raw materials.
[0005] To address the aforementioned issues, existing patents offer solutions. However, these solutions have certain limitations in practice. After prolonged use, most raw material screening devices experience clogging of the sieve holes, affecting the screening effect. This necessitates significant time for disassembly, cleaning, and maintenance of the raw material screening device, which is quite inconvenient.
[0006] Therefore, a raw material screening device for tobacco processing is proposed. Utility Model Content

The rotating arc frame is rotatably connected to the connecting pipe via hinges. The top of the connecting block is fixedly connected to the bottom of the vibrating ring.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] A raw material screening device for tobacco processing includes a waste rack 1, a material pipe 3 and a connecting pipe 4 are provided inside the waste rack 1, a screening mechanism 5 and an adjustment mechanism 6 are provided on the top of the connecting pipe 4, and two first electric telescopic columns 8 are fixedly connected inside the waste rack 1.
[0030] The screening mechanism 5 includes a vibrating ring 501, four screening frames 502, four hinges 503, a rotating arc frame 504, four connecting blocks 505, and four sealing gaskets 506. The top of the vibrating ring 501 contacts the bottom of the screening frame 502. The side of the screening frame 502 near the rotating arc frame 504 is fixedly connected to the rotating arc frame 504. The connection between the rotating arc frame 504 and the connecting pipe 4 is rotatably connected by the hinges 503. The top of the connecting block 505 is fixedly connected to the bottom of the vibrating ring 501. The surface of the sealing gasket 506 is fixedly connected to the inside of the rotating arc frame 504.
[0031] In this embodiment: by rotating the arc frame 504 and connecting pipe 4 through hinge 503, the arc frame 504 can easily drive the sealing gasket 506 and screening frame 502 to rotate, so that the top of the vibration ring 501 contacts the bottom of the screening frame 502. This facilitates the connecting block 505 to fix and support the vibration ring 501, and facilitates the vibration ring 501 to vibrate the screening frame 502, thereby facilitating the cleaning of debris blocking the inside of the screening frame 502.
[0032] Specifically, such as Figure 3 , Figure 5 As shown, the adjustment mechanism 6 includes a support frame 601 fixedly connected inside the connecting pipe 4, and an adjustment frame 604 is provided at the bottom of the support frame 601.
[0033] Specifically, such as Figure 5 As shown, four connecting posts 603 are fixedly connected to the top of the adjusting frame 604, and protective pads 602 are fixedly connected to the top of the connecting posts 603.
[0034] Specifically, such as Figure 5 As shown, a movable column 605 is fixed to the bottom of the adjusting frame 604, and a second electric telescopic column 606 is fixedly connected to the bottom of the movable column 605.
[0035] In this embodiment: by fixing the surface of the support frame 601 to the inside of the connecting pipe 4, the support frame 601 can be conveniently positioned to limit the screening frame 502, and the bottom of the protective pad 602 can be fixedly connected to the bottom of the connecting column 603. This makes it convenient for the connecting column 603 to drive the screening frame 502 to rotate through the protective pad 602, thus achieving the effect of conveniently driving the screening frame 502 to rotate.
[0036] Specifically, such as Figure 6As shown, a buffer pad 9 is fixedly connected to the top of the support frame 601, and an elastic pad 10 is fixedly connected to the top of the buffer pad 9.
[0037] Specifically, such as Figure 4 As shown, the top of the first electric telescopic column 8 is fixedly connected to the bottom of the connecting block 505, and the bottom of the first electric telescopic column 8 is fixedly connected to the bottom of the inside of the waste rack 1.
[0038] In this embodiment: by fixing the bottom of the elastic pad 10 to the top of the buffer pad 9, the elastic pad 10 can be conveniently positioned to limit the screening frame 502 through the buffer pad 9, and the top of the first electric telescopic column 8 can be fixedly connected to the bottom of the connecting block 505, thereby facilitating the movement of the connecting block 505 and achieving the effect of facilitating the movement of the connecting block 505.
[0039] Specifically, such as Figure 3 As shown, several limiting springs 7 are fixedly connected to the surface of the connecting pipe 4, and the surface of the limiting springs 7 is in contact with the surface of the rotating arc frame 504.
[0040] Specifically, such as Figure 1 As shown, two mounting brackets 2 are fixedly connected to the surface of the material pipe 3. The side of the mounting bracket 2 closest to the inside of the waste rack 1 is fixedly connected to the inside of the waste rack 1.
[0041] In this embodiment: by making the surface of the limiting spring 7 contact the surface of the rotating arc frame 504, the limiting spring 7 can easily limit the rotating arc frame 504, so that the surface of the mounting frame 2 is fixedly connected to the inside of the waste rack 1, thereby facilitating the fixing of the material pipe 3 and achieving the effect of fixing the material pipe 3.
[0042] Working principle: When cleaning the inside of the screening frame 502, the telescopic end of the second electric telescopic column 606 drives the adjusting frame 604 to move upward inside the connecting pipe 4 via the moving column 605. This causes the adjusting frame 604, through the connecting column 603, to bring the protective pad 602 into contact with the bottom of the screening frame 502. This, in turn, causes the hinge 503 to move the screening frame 502 away from the top of the support frame 601, facilitating the rotation of the rotating arc frame 504, which in turn causes the sealing pad 506 and the screening frame 502 to rotate. This, in turn, causes the first electric telescopic column 8 to move the vibrating ring 501 via the connecting block 505. The top of the vibrating ring 501 contacts the bottom of the screening frame 502, which facilitates the connection block 505 to fix and support the vibrating ring 501. Under the limit of the limiting spring 7, the vibrating ring 501 can vibrate the screening frame 502, which facilitates the cleaning of debris blocking the inside of the screening frame 502. The debris is then collected by the waste rack. This solves the problem that most existing raw material screening devices will experience clogging of the screen holes after long-term use, which affects the screening effect and requires a lot of time to disassemble, clean and maintain the raw material screening device, which is quite inconvenient.
[0043] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
