Description

Technical Field

[0001] The invention belongs to the technical field of conveying devices, and in particular relates to a tobacco shred anti-adhesion conveying device for a tobacco shred drying machine. Background Art

[0002] Baking tobacco shreds can further loosen and deform the shredded tobacco, increase the expansion and shaping of the leaf and stem shreds, thereby improving the filling capacity of the cigarette and making the tobacco aroma more intense; at the same time, through baking, the aroma components in the tobacco are released and revealed, improving the overall flavor of the tobacco.

[0003] At present, the tobacco drying process is that the front conveyor belt sends the tobacco into the tobacco drying machine, and the tobacco dried in the tobacco drying machine is sent to the subsequent processing equipment through the rear conveyor belt.

[0004] Tobacco drying machines usually use high-temperature airflow to quickly dehydrate tobacco, and their internal temperature is relatively high. The temperature of tobacco at the outlet of the tobacco drying machine can generally reach 40-60°C. During the transportation process of tobacco after baking, the tobacco on the conveyor belt is relatively static, making it difficult for the inner layer of tobacco to dissipate heat, and the temperature of the outer layer of tobacco is relatively low. This temperature difference also indirectly leads to inconsistent moisture content of the inner and outer layers of tobacco, thus affecting the sensory quality of cigarettes; at the same time, the high-temperature tobacco in the inner layer is easy to adhere to the rear conveyor belt, which is difficult to clean, resulting in waste of tobacco.

[0005] There are two existing methods for cooling tobacco after drying:

[0006] 1. Add a vibration structure to the conveyor belt at the rear end of the tobacco drying machine to turn the tobacco on the conveyor belt through vibration to increase the contact with air, thereby playing a certain cooling role. If the amplitude is small, the cooling effect on the middle and lower layers of tobacco is average; if the amplitude is large, it will cause the tobacco to break.

[0007] 2. A fan is installed above the rear conveyor belt to achieve the purpose of cooling through convection between air and tobacco. However, it is still difficult for the tobacco on the bottom layer to dissipate heat. At the same time, the aroma components of the upper layer of tobacco are easily lost after being blown by the wind, thus affecting the sensory quality of the cigarette.

[0008] Therefore, there is an urgent need for a conveying device for the rear end of the tobacco drying machine, which can help cool the tobacco after drying, prevent the tobacco from sticking, and improve the quality of the tobacco after drying. Summary of the invention

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 12 , the present invention provides a technical solution:

[0043] like Figure 1-Figure 12 As shown, a tobacco shreds anti-adhesion conveying device for a tobacco shreds drying machine is located at one side of a discharge port 1 of the shreds drying machine, and comprises a cooling conveying mechanism 2, a turning mechanism 3, a rear-end conveying belt 4 and a lifting mechanism 5. The cooling conveying mechanism 2 comprises a chain conveyor belt 21 and a cooling box 22. The cooling box 22 is clamped with the chain conveyor belt 21. The cooling box 22 moves horizontally through the chain conveyor belt 21. The cooling box 22 is located at the bottom of the discharge port 1 of the shreds drying machine. The cooling box 22 is opened on both sides along the conveying direction of the chain conveyor belt 21. The cooling box 22 is used to receive the dried shreds of tobacco. The bottom of the cooling box 22 is provided with heat dissipation fins 23.

[0044] The flip mechanism 3 is located on one side of the discharge end of the chain conveyor 21, and the flip mechanism 3 includes a driving base 33, a flip cylinder 31 and a baffle assembly 32. The flip cylinder 31 is provided with a slot 38 for clamping the cooling box 22, one end of the baffle assembly 32 is located in the slot 38, and a telescopic assembly 39 is provided in the slot 38 away from the baffle assembly 32. The cooling box 22 is abutted against the baffle assembly 32 through the telescopic assembly 39, and the cooling box 22 is flipped by the flip cylinder 31;

[0045] The rear conveyor belt 4 is located on the side of the flipping mechanism 3 away from the chain conveyor belt 21, and the tobacco in the cooling box 22 falls into the rear conveyor belt 4 after flipping;

[0046] The lifting mechanism 5 is located at the bottom of the cooling conveying mechanism 2 and the turning mechanism 3. The lifting mechanism 5 includes a lifting belt 51 and a horizontal positioning platform 52. The horizontal positioning platform 52 is located at the bottom of the front end side of the chain conveyor belt 21. The high point side of the lifting belt 51 is connected to the horizontal positioning platform 52. The bottom horizontal section of the lifting belt 51 is located at the bottom of the turning mechanism 3. The turned cooling box 22 enters the horizontal positioning platform 52 through the lifting belt 51. A lifting component 53 is provided in the horizontal positioning platform 52. The cooling box 22 on the horizontal positioning platform 52 is connected to the chain conveyor belt 21 through the lifting component 53.

[0047] Through the above technical solution, the tobacco shreds after drying fall into the cooling box 22 through the discharge port 1 of the tobacco drying machine. The cooling box 22 moves to the turning mechanism 3 through the chain conveyor belt 21. During the movement, the upper layer of tobacco shreds in the cooling box 22 contacts the air for rapid cooling. The high-temperature tobacco shreds at the bottom of the cooling box 22 contacts the bottom plate of the cooling box 22. The heat is extracted through the heat dissipation fins 23. At the same time, the fans 28 on both sides of the chain conveyor belt 21 blow away the heat extracted by the heat dissipation fins 23, so that the cold wind does not directly blow the tobacco shreds, thereby avoiding the loss of the aroma in the tobacco shreds and improving the cooling effect. When the cooling box 22 enters the slot 38 of the turning mechanism 3, the telescopic component 39 lifts the cooling box 22 and contacts the baffle component 32, so that the baffle component 32 blocks the cooling box 22 to avoid the leakage of tobacco shreds during the subsequent turning process. When the turning mechanism 3 turns over, the tobacco shreds in the cooling box 22 fall into the rear conveyor belt 4. At this time, the tobacco shreds are turned upside down, and the original bottom layer of tobacco shreds face upward, and the cooling effect is further improved by contact with the air. As the turning mechanism 3 turns over, the cooling box 22 falls vertically into the lifting mechanism 5, and is reconnected to the chain conveyor belt 21 through the lifting mechanism 5, so that the cooling box 22 is located below the tobacco drying machine outlet 1 again, and the tobacco is continuously cooled and conveyed.

[0048] The specific process of this program is as follows:

[0049] like Figure 1-Figure 3 As shown, the chain conveyor 21 includes two groups of chain belts 24 arranged symmetrically. A mounting box 25 is provided outside the chain belt 24 for protecting the internal chain belt 24. The chain belt 24 is driven by corresponding gears (not shown in the figure). The two groups of chain belts 24 are connected by a transmission shaft and rotate synchronously. At the same time, a plurality of support shafts are provided between the transmission shafts to support the chain belts 24 and prevent them from falling (not shown in the figure). It can be known that no support shaft is provided at the position corresponding to the horizontal positioning platform 52 to keep the upper and lower parts unobstructed, so as to facilitate the subsequent lifting of the cooling box 22.

[0050] The chain belt 24 is composed of a plurality of hinged chain blocks, each of which is provided with a V-shaped block 26 on the top. At the same time, there are side walls on both sides of the width of the cooling box 22, which prevent the tobacco from falling from both sides. The cooling box 22 has no side wall obstruction along the length direction, which facilitates the tobacco to fall out of the opening after flipping. A spring rod 29 is provided on the side wall along the width direction of the cooling box 22, and the spring rod 29 can be retracted. The V-shaped groove size of the V-shaped block 26 matches the diameter of the spring rod 29, so the spring rod 29 is clamped on the V-shaped block 26, and the cooling box 22 is supported on the V-shaped block 26 through the spring rod 29, so when the V-shaped block 26 is driven with the chain belt 24, the V-shaped block 26 drives the spring rod 29 and the cooling box 22 to move together.

[0051] Continue as Figure 1 and Figure 2 As shown, the discharge port 1 of the wire drying machine is close to the front end of the chain conveyor 21. The discharge port 1 of the wire drying machine is provided with a solenoid valve and a visual sensor. When the front end of the cooling box 22 is located at the lower end of the discharge port 1 of the wire drying machine, the solenoid valve is opened to allow the roasted tobacco to fall into the cooling box 22. During the falling process of the tobacco, the cooling box 22 moves to the right. Since a scraper 210 is provided on the right side of the discharge port 1 of the wire drying machine, the scraper 210 can be used to scrape the accumulated tobacco flat, ensuring that the height of the tobacco does not exceed the height of the cooling box 22, so that the subsequent baffle assembly 32 can directly cover the cooling box 22 to prevent the tobacco from falling out. At the same time, the scraper 210 can flatten the tobacco, increase the surface area of ​​the tobacco, and improve the cooling effect.

[0052] At the same time, a fan 28 is provided on the inner side of the mounting box 25. The height of the fan 28 is the same as that of the heat dissipation fins 23. The fan 28 is located away from the horizontal positioning platform 52. When the cooling box 22 after receiving the material moves along the chain conveyor 21, the tobacco on the upper layer of the cooling box 22 contacts with the air for rapid cooling, and the high-temperature tobacco on the bottom layer of the cooling box 22 contacts with the cooling box 22. The heat is discharged through the heat dissipation fins 23. At the same time, the heat discharged from the heat dissipation fins 23 is blown away by the fans 28 on both sides of the chain conveyor 21, so that the cold wind does not directly blow the tobacco, thereby avoiding the loss of aroma in the tobacco and improving the cooling effect.

[0053] like Figure 4 As shown, after receiving the materials, the cooling box 22 moves to the front of the turning mechanism 3 along the chain conveyor 21 , and at this time, the baffle assembly 32 is horizontally located above the cooling box 22 .

[0054] like Figure 5 As shown, the cooling box 22 is fed into the slot 38 of the flipping cylinder 31 through the chain conveyor 21. Since the V-groove of the V-block 26 is movably connected to the spring rod 29, the spring rod 29 can be easily separated from the V-block 26. As one end of the cooling box 22 presses against the inner wall of the slot 38, the flipping mechanism 3 starts the flipping operation.

[0055] like Figure 6 As shown, one end of the cooling box 22 is pressed against the inner wall of the slot 38. Since the telescopic assembly 39 includes a telescopic cylinder, a support plate and a sensor, the cylinder body of the telescopic cylinder is located in the slot, the support plate is connected to the piston rod of the telescopic cylinder, and the sensor is located in the support plate. Therefore, when the sensor in the telescopic assembly 39 detects the cooling box 22 above, the telescopic cylinder drives the support plate to contact the heat dissipation fins 23 of the cooling box 22. As the telescopic cylinder continues to rise, the upper surface of the cooling box 22 contacts the baffle assembly 32 to complete the sealing, and at the same time, the spring rod 29 of the cooling box 22 also comes off the V-block 26.

[0056] like Figure 7 As shown, the cooling box 22 is fixed as a whole with the turning cylinder 31 through the telescopic assembly 39, and the turning cylinder 31 rotates clockwise through the driving base 33 at the bottom. After the turning, one end of the cooling box 22 faces downward and is located above the rear conveying belt 4. Since the length of the cooling box 22 is adapted to the length of the fixing plate 36 and the second folding plate 35, the first folding plate 34 extends out of the cooling box 22. The first folding plate 34 is used as a material receiving plate to facilitate the transition of the tobacco in the cooling box 22 to the rear conveying belt 4 to prevent the tobacco from falling. At the same time, the rear conveying belt 4 is continuously driven, and the tobacco in the cooling box 22 continuously falls on the rear conveying belt 4. At the same time, the width of the rear conveying belt 4 is greater than the width of the cooling box 22, so the tobacco will be concentrated on the rear conveying belt 4 and will not fall out. At this time, the tobacco is turned upside down after turning, and the tobacco at the original bottom layer faces upward, which can further improve the cooling effect after contacting with the air. At the same time, the rear conveying belt 4 is also provided with a scraper 210 to ensure that the tobacco is spread evenly and increase the contact area with the air to improve the cooling effect.

[0057] like Figure 8 As shown, as the turning cylinder 31 turns, the cooling box 22 passes over the rear conveying belt 4. At this time, the tobacco in the cooling box 22 has been completely poured into the rear conveying belt 4. The end of the cooling box 22 does not contact the rear conveying belt 4. Only the first folding plate 34 abuts against the front end of the rear conveying belt 4. Therefore, when the first folding plate 34 abuts against the rear conveying belt 4, since the first folding plate 34 is hinged to the second folding plate 35, the first folding plate 34 is folded under contact with the rear conveying belt 4 to ensure that the first folding plate 34 can pass through the rear conveying belt 4. After passing, the first folding plate 34 is reset under the action of the torsion spring.

[0058] like Fig. 9 As shown, the cooling box 22 is in a vertical downward position as it is flipped. At this time, the telescopic assembly is reset, and the cooling box 22 falls out of the slot 38 and falls vertically onto the lifting belt 51 below. Since the heat dissipation fins 23 of the cooling box 22 face right, the center of gravity of the cooling box 22 also leans to the right. At the same time, the lifting belt 51 moves to the left, and the cooling box 22 as a whole will fall to the right.

[0059] Since the lifting belt 51 is provided with an inclined slide plate 54, the cooling box 22 contacts the slide plate 54 before falling down, thereby preventing the cooling box 22 from falling down and playing a certain buffering role. At the same time, the highest point of the slide plate 54 can ensure that the first folding plate 34 passes through without interference when the turning cylinder 31 turns over.

[0060] The cooling fins 23 of the fallen cooling box 22 face downwards. Since the lifting belt 51 is provided with a convex strip 55, the width of the convex strip 55 is the same as the gap between two adjacent cooling fins 23, so the cooling fins 23 can be engaged with the convex strip 55, and the cooling box 22 is driven to move by the convex strip 55 to prevent the cooling box 22 from shaking during the lifting process. With the movement of the lifting belt 51, the cooling box 22 enters the horizontal positioning platform 52, and the front end and both sides of the horizontal positioning platform 52 are provided with baffles, so that the cooling box 22 is completely limited after entering and no longer moves, which facilitates the subsequent lifting assembly 53 to be lifted to a suitable position.

[0061] like Fig.10 As shown, since the lifting assembly 53 includes a lifting cylinder and a push plate, the cylinder body of the lifting cylinder is located below the horizontal positioning platform 52, the push plate is flush with the upper surface of the horizontal positioning platform 52, and the push plate is fixed to the piston rod of the lifting cylinder. When the cooling box 22 is in place on the horizontal positioning platform, the lifting cylinder in the lifting assembly 53 drives the push plate to lift the cooling box 22, and the spring rods 29 on both sides of the cooling box 22 abut against the side walls on the horizontal positioning platform to play a limiting role. As the lifting cylinder moves, the cooling box 22 approaches the installation box 25 above. Since the top of the installation box 25 is an inwardly contracted inclined surface 27, the spring rod 29 will be compressed. As the cooling box 22 moves to the position of the V-block 26, the spring rod 29 is reset and inserted into the V-block 26 to complete the positioning, and the cooling box 22 is connected to the chain conveyor 21.

[0062] like Fig.11 As shown, during the process of the cooling box 22 being lifted by the lifting belt 51 , the turning mechanism 3 continues to turn over, and at this time, the second folding plate 35 contacts the roller 211 at the front end of the chain conveyor belt 21 .

[0063] like Fig.12 As shown, as the turning cylinder 31 continues to rotate, the second folding plate 35 is hinged with the fixed plate 36, and the second folding plate 35 is turned over to facilitate the second folding plate 35 and the first folding plate 34 to pass through. Since the first folding plate 34 and the fixed plate 36 are also connected by a tension spring 37, the second folding plate 35 is reset under the action of the tension spring 37 after passing through. Figure 1 After the turnover mechanism 3 is reset, the slot 38 is aligned with the discharge port of the chain conveyor belt 21, and the baffle assembly 32 is in a horizontal state.

[0064] Furthermore, the bottom and side walls of the cooling box 22 and the rear conveying belt 4 are coated with an anti-stick coating, and the anti-stick coating can be a PFA anti-stick coating to prevent the tobacco from sticking during cooling and conveying, thereby reducing waste during tobacco conveying.

[0065] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
