[0031] 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.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] like Figures 1 to 4 As shown, this utility model embodiment provides a conveying device for tobacco processing, which includes a frame 1, a conveyor belt 2, a drive motor 3, a feed hopper 6, and two limiting frames 19. A main drive roller 4 and a driven drive roller are rotatably arranged on the left and right sides of the top of the frame 1, respectively, and the main drive roller 4 and the driven drive roller are connected by the conveyor belt. The drive motor 3 is mounted on the front side plate of the frame 1, and the output shaft of the drive motor passes through the front side plate of the frame and is coaxially connected to the front end of the main drive roller 4. The feed hopper 6 is located on the left side of the top of the frame, and a filter frame 8 is provided in the feed hopper. The two limiting frames 19 are arranged opposite each other on the front and rear sides of the frame, and a guide plate 25 is horizontally arranged on the top of each of the two limiting frames. The opposite sides of the two guide plates are both inclined surfaces 26, and the distance between the two inclined surfaces 26 gradually decreases from left to right.

[0036] The tobacco conveying device provided in this embodiment of the invention utilizes a filter frame 8 installed in the feed hopper to perform a screening function, filtering out impurities from the tobacco material and improving product quality. Simultaneously, because the distance between the inclined surfaces 26 on the two guide plates 25 gradually decreases from left to right, these two inclined surfaces effectively guide the tobacco material towards the center of the conveyor belt, achieving centered conveying of the tobacco material and thus improving the processing efficiency of subsequent processes, thereby increasing overall production efficiency. Therefore, this invention effectively achieves the screening and guidance of tobacco material.

[0037] Furthermore, an opening 7 is provided on the front side plate of the feed hopper 6, and the filter frame 8 is slidably engaged with the opening 7, thus slidably disposed within the feed hopper 6. This design allows for convenient removal of the filter frame 8 from the feed hopper 6 for replacement or repair.

[0038] Specifically, a handle 10 is provided on the front side of the filter frame 8, so that the filter frame can be easily pulled using the handle 10. It can be understood that the bottom of the filter frame has filter holes 9, which can realize the preliminary screening of tobacco materials and effectively prevent large-sized impurities from falling onto the conveyor belt.

[0039] Furthermore, the front side plate of the feed hopper 6 is provided with a locking component for locking the filter frame, thereby effectively preventing the filter frame from falling out of the feed hopper.

[0040] Specifically, the locking assembly includes a pull plate 16, two limiting blocks 14, and two fixing blocks 11. The two fixing blocks 11 are arranged opposite each other below the opening, and the two limiting blocks are slidably disposed in the two fixing blocks 11 respectively. The pull plate 16 is located below the fixing blocks. The lower ends of the two limiting blocks are vertically provided with pull rods 15. The lower ends of the two pull rods pass through the bottom of the two fixing blocks and are connected to the pull plate. A spring 13 is provided between the bottom of the limiting block and the bottom of the fixing block. Using this design, pulling down the pull plate 16 causes the two pull rods 15 to move the two limiting blocks downwards, so that the upper ends of the two limiting blocks 14 are respectively located within the two fixed blocks. This releases the lock on the filter frame, allowing it to be easily pulled out of the hopper. Once the filter frame is inserted into the hopper, releasing the pull plate causes the spring's restoring force to push the two limiting blocks upwards within the two fixed blocks until their upper ends protrude from the upper ends of the fixed blocks, thus locking the filter frame. The blocking action between the upper ends of the two limiting blocks and the front end of the filter frame effectively prevents the filter frame from slipping out of the opening. This locking assembly enables quick locking and unlocking of the filter frame, ensuring its stable installation while greatly facilitating cleaning and maintenance. It is understood that the upper ends of the limiting blocks are used to block the front side of the filter frame.

[0041] Preferably, a through hole 23 is provided at the center of the pull plate 16, so that the pull plate can be easily pulled through the through hole. It is understood that the fixed block has a receiving groove 12 for the limit block to slide up and down. Multiple support rollers can be evenly arranged between the main drive roller and the driven roller, with the front and rear ends of each support roller rotatably connected to the frame, so as to better support the conveyor belt. From left to right, the inclined surface of the guide plate extends gradually towards the center of the conveyor belt.

[0042] Furthermore, a vibrator 21 is provided on the left side of the feed hopper 6. This design utilizes the vibrator to drive the feed hopper to vibrate, effectively preventing the accumulation of tobacco material and promoting its uniform distribution, thus ensuring a smooth and efficient screening process.

[0043] Specifically, a brush plate 22 can be fixedly connected to the right end of the frame 1. The brush plate is provided with bristles for contacting the conveyor belt 2. With this solution, the bristles can effectively remove residual materials on the conveyor belt, keep the conveyor belt 2 clean, and prevent cross-contamination between different materials.

[0044] Furthermore, the tobacco processing conveying device also includes a drive assembly. The lower ends of the two limiting frames are slidably mounted on the bottom of the frame, and the drive assembly is used to drive the two limiting frames 19 to move closer or further apart. This design allows the two limiting frames to move closer or further apart according to the processing requirements of subsequent processes, flexibly adjusting the distance between the inclined surfaces of the two guide plates. This, in turn, flexibly adjusts the degree of tobacco material aggregation, ensuring that the tobacco material is evenly concentrated in the middle of the conveyor belt, thereby facilitating subsequent processing and improving overall production efficiency.

[0045] Specifically, the drive assembly includes a drive motor 18 and a double-ended reverse screw 17. The rear end and middle portion of the double-ended reverse screw 17 are rotatably mounted on the rear end and middle portion of the bottom of the frame, respectively. The lower ends of the two limiting brackets are respectively provided with threaded holes for engaging with the front and rear sections of the double-ended reverse screw. The drive motor is mounted on the front side plate of the frame, and the output shaft of the drive motor is coaxially connected to the front end of the double-ended reverse screw. With this design, when the drive motor 18 starts, it drives the double-ended reverse screw 17 to rotate. Since the lower ends of the two limiting brackets are threadedly engaged with the double-ended reverse screw, the two limiting brackets will move along the double-ended reverse screw 17 when the double-ended reverse screw rotates, thereby causing the two limiting brackets to move closer or further apart, and thus adjusting the distance between the inclined surfaces 26 of the two diverting plates 25. Understandably, the threads of the front and rear sections of the double-ended reverse screw rotate in opposite directions. The threaded hole on the limit frame located on the front side of the frame engages with the threaded section of the front section of the double-ended reverse screw, and the threaded hole on the limit frame located on the rear side of the frame engages with the threaded section of the rear section of the double-ended reverse screw.

[0046] Preferably, a control panel 5 is fixedly connected to the front side plate of the frame 1. The control panel 5 is equipped with buttons for controlling the drive motor 3, drive motor 18 and vibrator 21 respectively.

[0047] Specifically, two stabilizing plates 27 are arranged opposite each other on the bottom of the frame 1. Each stabilizing plate has an elongated stabilizing hole 20 extending in the front-to-back direction. The lower end of the limiting frame has two sliders that slide in a one-to-one correspondence with the two elongated stabilizing holes. This design, utilizing the cooperation between the sliders and the elongated stabilizing holes, effectively prevents the limiting frame from shifting or wobbling during movement, enhancing its operational stability. Preferably, the sliders have a T-shaped structure, which better prevents them from detaching from the elongated stabilizing holes.

[0048] The general working principle of this utility model is as follows: During use, the degree of aggregation of tobacco material is adjusted according to the needs of subsequent processing. Specifically, by operating the corresponding button on the control panel 5, the drive motor 18 is started, which drives the double-headed reverse screw 17 to rotate. The double-headed reverse screw 17 drives the two limit frames 19 to move along the elongated stabilizing hole 20. After the two guide plates are adjusted to the appropriate position, the drive motor 18 is turned off. Then, by operating the corresponding button on the control panel, the drive motor 3 is started, which drives the main drive roller to rotate, causing the conveyor belt 2 to run. Then, the tobacco material is added from the top of the feed hopper 6. Subsequently, the tobacco material will be screened by the filter frame 8 and fall onto the conveyor belt 2. When the tobacco material is conveyed to the right by the conveyor belt, it will be guided by the inclined surfaces of the two guide plates to the middle position of the conveyor belt 2, thereby transporting it to the next... The process involves several steps. During the feeding process, tobacco material may accumulate on top of the filter frame 8. At this time, the vibrator 21 can be activated to generate vibration, thereby promoting the even distribution of tobacco material onto the conveyor belt 2. After a period of use, the filter frame 8 needs to be cleaned to prevent excessively large tobacco material from clogging it. During cleaning, first press down on the pull plate 16. The pull plate 16 drives the limiting blocks 14 downward through the pull rods 15 on both sides. When the upper surfaces of the two limiting blocks 14 are below the opening 7, the limiting blocks will not interfere with the forward and backward movement of the filter frame in the opening. This allows the filter frame 8 to be easily removed for cleaning. After cleaning, the filter frame 8 is installed into the feed hopper along the opening 7. Then, the pull plate 16 is released, and the restoring force of the spring 13 will reset the two limiting blocks 14 to lock the filter frame 8.

[0049] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
