Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf drying technology, and in particular to a tobacco sheet drying device. Background Technology

[0002] Tobacco sheets, also known as reconstituted tobacco leaves or homogenized tobacco leaves, are mainly composed of tobacco dust, fragments, tobacco stems or low-grade tobacco leaves with adhesives and other additives. They can be mixed together with a medium and rolled or scattered into sheets of uniform thickness and quality. The manufacturing methods are mostly papermaking, slurry making and rolling.

[0003] Current methods for drying tobacco sheets mostly involve laying the formed but damp tobacco sheets flat on a surface for natural air drying or using a dryer. However, this method requires frequent flipping of the sheets to ensure the drying effect, making the process cumbersome and impractical. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tobacco sheet drying device, which solves the above-mentioned defects of the prior art.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] This utility model provides a tobacco sheet drying device, including a base plate. Vertical plates are fixedly connected to both sides of the upper surface of the base plate. An arc-shaped hopper is provided between the two vertical plates. Connecting plates are fixedly connected to both sides of the middle of the arc-shaped hopper, and the upper ends of the two connecting plates are rotatably connected to the two vertical plates via shafts. One of the vertical plates is equipped with a forward and reverse motor to drive the connecting plate to reciprocate. The upper ends of the two vertical plates are fixedly connected to the same top plate, which is equipped with an air supply component for blowing hot air downwards. Two fixed side plates and two folding side plates are fixedly connected to both sides of the top plate. An L-shaped scraper that abuts against the inner arc surface of the arc-shaped hopper is fixedly connected to the lower ends of both the fixed and folding side plates. The folding side plates can drive the L-shaped scraper below them to switch between a first state and a second state. In the first state, the folding side plates are unfolded, and the L-shaped scraper is located below. In the second state, the folding side plates are folded, and the L-shaped scraper is located above.

[0007] This application employs the aforementioned tobacco sheet drying device. After the tobacco sheets are laid flat on the inner arc surface of the arc-shaped hopper, hot air is supplied to the inner wall of the arc-shaped hopper through the air supply component to pre-dry the surface of the sheets. After the surface of the sheets is pre-dried, the forward and reverse motor is started to drive the connecting plate and the arc-shaped hopper to swing back and forth. As the arc-shaped hopper swings, the fixed L-shaped scraper scrapes the sheets off the arc surface of the inner wall of the arc-shaped hopper and loosens them. Under the action of gravity, they fall to the bottom and continue to dry. After the drying process is completed, the folding side plate is folded so that the L-shaped scraper flips to the top, and the sheets in the arc-shaped hopper can be taken out.

[0008] Preferably, in the above technical solution, the air supply component includes an ion fan fixedly installed on the top plate, the air outlet of the ion fan is located below the top plate, and a heating wire is fixedly installed above the two vertical plates, with the heating wire located at the air outlet of the ion fan.

[0009] Preferably, in the above technical solution, a digital display controller is fixedly installed on the side wall of one of the upright plates, and the output terminal of the digital display controller is electrically connected to the input terminals of the forward and reverse motor, the heating wire and the ion fan respectively.

[0010] Preferably, in the above technical solution, the folding side panel includes an upper side panel and a lower side panel, which are rotatably connected by a hinge, and the upper side panel is provided with a pin assembly for fixing the lower side panel to the unfolded state.

[0011] Preferably, in the above technical solution, the pin assembly includes a pin sleeve fixedly connected to the upper side plate, a pin is inserted into the pin sleeve, and a fixing sleeve that is inserted into the pin is fixedly connected to the lower side plate.

[0012] Preferably, in the above technical solution, a magnetic plate is fixedly connected to the end of the pin, and the magnetic plate is magnetically connected to the iron pin sleeve.

[0013] Preferably, in the above technical solution, both ends of the arc-shaped hopper are fixedly connected with inclined guide plates, and the two inclined guide plates are respectively adapted to two L-shaped scrapers.

[0014] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0015] This application uses an air supply component to deliver hot air to the inner wall of an arc-shaped hopper to initially dry the surface of the tobacco sheet. After the surface of the sheet is initially dry, a forward and reverse motor is started to drive the connecting plate and the arc-shaped hopper to swing back and forth. As the arc-shaped hopper swings, a fixed L-shaped scraper scrapes off and loosens the sheet on the arc surface of the inner wall of the arc-shaped hopper. Under the action of gravity, the sheet falls to the bottom and continues to dry, thus completing the drying process. This avoids frequent turning of the tobacco sheet and improves the drying effect and efficiency. Attached Figure Description

[0022] 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 arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0023] Unless otherwise specified, the experimental methods used in the following examples are conventional methods, and the materials and reagents used are commercially available. Unless otherwise specified, the equipment used in the experiments is well known to those skilled in the art.

[0024] like Figs. 1-3As shown, this application discloses a tobacco sheet drying device, including a base plate 1. Vertical plates 2 are fixedly connected to both sides of the upper surface of the base plate 1. An arc-shaped hopper 4 is provided between the two vertical plates 2. Connecting plates 5 are fixedly connected to both sides of the middle of the arc-shaped hopper 4. The upper ends of the two connecting plates 5 are rotatably connected to the two vertical plates 2 respectively via shafts. One of the vertical plates 2 is equipped with a forward / reverse motor 6 for driving the connecting plate 5 to rotate back and forth. The upper ends of the two vertical plates 2 are fixedly connected to the same top plate 7. The top plate 7 is equipped with an air supply component for blowing hot air downwards. Two fixed side plates 9 and two folding side plates 10 are fixedly connected to both sides of the top plate 7 respectively. Both the folding side plate 10 and the lower end of the folding side plate 10 are fixedly connected to an L-shaped scraper 11 that abuts against the inner arc surface of the arc-shaped hopper 4. The folding side plate 10 can drive the L-shaped scraper 11 below it to switch between a first state and a second state. In the first state, the folding side plate 10 is unfolded and the L-shaped scraper 11 is located below. In the second state, the folding side plate 10 is folded and the L-shaped scraper 11 is located above. It is worth mentioning that the horizontal parts of the two L-shaped scrapers 11 are both designed to be inclined and are on the same axis as the arc-shaped hopper 4. This design allows the horizontal parts of the L-shaped scrapers 11 to always abut against the inner arc surface of the arc-shaped hopper 4 when the arc-shaped hopper 4 is reciprocating, scraping off the thin sheet on its arc surface.

[0025] As an optional implementation, the air supply component includes an ion fan 8 fixedly installed on the top plate 7. The air outlet of the ion fan 8 is located below the top plate 7. A heating wire 12 is fixedly installed above the two vertical plates 2, and the heating wire 12 is located at the air outlet of the ion fan 8. A digital display controller 14 is fixedly installed on the side wall of one of the vertical plates 2. The output terminal of the digital display controller 14 is electrically connected to the input terminals of the forward and reverse motor 6, the heating wire 12, and the ion fan 8, respectively. The ion fan 8 can be controlled to blow air and control the heating temperature of the heating wire 12 through the digital display controller 14. This can realize that the blowing of ion air can drive the hot air around the heating wire 12 to blow onto the inner bottom arc surface of the arc-shaped bottom hopper 4 to dry the thin sheet on the inner bottom. The ion fan 8 can effectively remove the static electricity in the air, realize the yellowing and rapid drying of tobacco sheets, and improve the drying effect. At the same time, the forward and reverse motor 6 is the prior art. The rotation amplitude and rotation frequency of the forward and reverse motor can be realized by simple programming by those skilled in the art. This application mainly protects the mechanical structure, so this application will not explain the control method and circuit connection in detail.

[0026] Reference Fig. 2As shown, the folding side panel 10 includes an upper side panel 101 and a lower side panel 102, which are rotatably connected by a hinge 103. The upper side panel 101 is provided with a pin assembly 3 for fixing the lower side panel 102 to the unfolded state. The pin assembly 3 includes a pin sleeve 3a fixedly connected to the upper side panel 101, in which a pin 3b is inserted. A fastener that is inserted into the pin 3b is fixedly connected to the lower side panel 102. The end of the fixed sleeve 3c and the pin 3b is fixedly connected to a magnetic plate 3d, and the magnetic plate 3d is magnetically connected to the iron pin sleeve 3a. Due to the design of the hinge 103, the lower side plate 102 can only rotate 180 degrees. After the lower side plate 102 is unfolded, the pin 3b is inserted into the pin sleeve 3a and the fixed sleeve 3c at the same time to fix the lower side plate 102 and prevent it from shaking. At the same time, the magnetic force of the magnetic plate 3d can prevent the pin 3b from falling off.

[0027] Furthermore, both ends of the arc-shaped hopper 4 are fixedly connected with inclined guide plates 13, and the two inclined guide plates 13 are respectively adapted to the two L-shaped scrapers 11. When the arc-shaped hopper 4 swings back and forth, the inclined guide plates 13 first abut against the horizontal part of the L-shaped scrapers 11, avoiding the collision between the L-shaped scrapers 11 and the end of the arc-shaped hopper 4, thereby guiding the L-shaped scrapers 11 into the interior of the arc-shaped hopper 4 and continuously contacting its bottom arc surface.

[0028] Using the above structure, after the tobacco sheets are laid flat on the inner arc surface of the arc-shaped hopper 4, hot air is delivered to the inner wall of the arc-shaped hopper 4 through the air supply component to pre-dry the surface of the sheets. After the surface of the sheets is pre-dried, the forward and reverse motor 6 is started to drive the connecting plate 5 and the arc-shaped hopper 4 to swing back and forth. As the arc-shaped hopper 4 swings, the fixed L-shaped scraper 11 scrapes the sheets off the arc surface of the inner wall of the arc-shaped hopper 4 and loosens them. Under the action of gravity, they fall to the bottom and continue to dry. After drying, the drying process is completed. At this time, the folding side plate 10 is folded so that the L-shaped scraper 11 is flipped to the top, and the sheets in the arc-shaped hopper 4 can be taken out.

[0029] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
