Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically to a tobacco pipe belt feeding mechanism. Background Technology

[0002] In the tobacco processing industry, the automated feeding and conveying of tobacco tubes is a key link in ensuring efficient and continuous production. With the rapid development of the tobacco industry and the continuous growth of market demand, improving production efficiency, reducing labor costs, and optimizing production processes have become the focus of attention for all manufacturers. However, in traditional tobacco processing, the feeding and conveying methods for tobacco tubes still have many shortcomings, especially in the conveying process from the unloading bin to the fixture, where this problem is particularly prominent.

[0003] Currently, the widely used tobacco tube feeding and conveying equipment mainly relies on a distribution disc system. The working principle of this system is to pre-place a large number of tobacco tubes in a feeding hopper, and then guide them onto a conveyor belt one by one or in batches through a distribution disc structure located at the bottom of the hopper. The conveyor belt then transports these tobacco tubes to the fixture for subsequent tobacco filling operations. Although this distribution disc system achieves a certain degree of automation in tobacco tube conveying, its inherent limitations severely restrict the improvement of production efficiency. Specifically, because the design principle of the distribution disc dictates that tobacco tubes must pass through one by one or in batches, the number of tobacco tubes that can be conveyed per unit time is limited. In a high-speed, large-scale tobacco processing environment, this inefficient conveying method directly affects the speed of the overall production line, increasing production cycles and costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a smoke pipe belt feeding mechanism, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cigarette pipe belt feeding mechanism, comprising a fixedly connected rear support plate and a front support plate. The rear support plate has a first driving synchronous pulley, several first driven synchronous pulleys, a second driving synchronous pulley, and several second driven synchronous pulleys rotatably connected inside. A first synchronous belt is fitted around the first driving synchronous pulley and several first driven synchronous pulleys. A second synchronous belt is fitted around the second driving synchronous pulley and several second driving synchronous pulleys. The adjacent end faces of the first and second synchronous belts are designated as the cigarette pipe conveying area. A drive motor is mounted on the back of the rear support plate. The drive end of the drive motor is connected to the first and second driving synchronous pulleys via a gear set. The driving of the first and second driving synchronous pulleys causes the first and second synchronous belts to rotate in opposite directions.

[0006] Furthermore, a feeding hopper is installed on the top of the front side of the rear support plate, and a smoke pipe buffer is symmetrically connected inside the feeding hopper. The smoke pipe buffer has a semi-circular structure, and the outlet of the feeding hopper corresponds to the conveying inlet of the first synchronous belt and the second synchronous belt.

[0007] Furthermore, the drive end of the drive motor is connected to the power input end of the reducer, and the power output end of the reducer is connected to the power input end of the gear set.

[0008] Furthermore, an adaptive limiting module is installed on the surface of both the rear support plate and the front support plate, and the inlet of the adaptive limiting module corresponds to the conveying outlet of the first synchronous belt and the second synchronous belt.

[0009] Furthermore, the adaptive limiting module includes an upper baffle plate and a side baffle plate installed on the front of the front support plate. The rear support plate and the front support plate are rotatably connected to a rotating seat. The front end of the rotating seat extends to the front of the front support plate and is connected to a movable baffle plate. The rear end of the rotating seat extends to the back of the rear support plate and is connected to a swing arm. A convex shaft is connected to the back of the rear support plate. A spring is connected between the convex shaft and the bottom end of the swing arm.

[0010] Furthermore, limit shafts and gas springs are installed on both sides of the back of the rear support plate and on both sides within the rotation range of the top of the swing arm.

[0011] This utility model provides a conveyor belt feeding mechanism for flue pipes. Compared with the prior art, it has the following advantages:

[0012] Compared to traditional material distribution disc feeding systems, this flue pipe belt feeding mechanism, by adopting a design with two synchronous belts (i.e., the first synchronous belt and the second synchronous belt) rotating in parallel and in opposite directions, can simultaneously utilize the friction between the uppermost and lowermost layers of the flue pipe and the synchronous belts to achieve continuous and stable movement of the flue pipe within the conveying area. This design greatly increases the number of flue pipes conveyed per unit time, significantly shortens the production cycle, and improves overall production efficiency. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-6This utility model provides a technical solution: a flue gas pipe belt feeding mechanism, comprising a rear support plate 1, a front support plate 2, a first driving synchronous pulley 3, several first driven synchronous pulleys 4, second driving synchronous pulleys 5, several second driven synchronous pulleys 6, a first synchronous belt 7, a second synchronous belt 8, a drive motor 9, a gear set 10, a feeding bin 11, a reducer 12, an adaptive limit module 13, and a flue gas pipe conveying area 14. The rear support plate 1 and the front support plate 2 are fixedly connected by several tie bolts. The first driving synchronous pulley 3, several first driven synchronous pulleys 4, second driving synchronous pulleys 5, and several second driven synchronous pulleys 6 are all rotatably connected to the front of the support plate 1. The first driving synchronous pulleys 3 and 5 are located at the flue gas pipe conveying area. The starting point of the conveying position is where several first driven synchronous pulleys 4 and several second driven synchronous pulleys 6 are distributed according to the conveying path of the smoke pipe. The first synchronous belt 7 is fitted outside the first driving synchronous pulley 3 and several first driven synchronous pulleys 4, and the second synchronous belt 8 is fitted outside the second driving synchronous pulley 5 and several second driven synchronous pulleys 6. That is to say, when the first driving synchronous pulley 3 and the second driving synchronous pulley 5 rotate, the corresponding first synchronous belt 7 and the second synchronous belt 8 will rotate synchronously. The smoke pipe conveying area 14 is located between the first synchronous belt 7 and the second synchronous belt 8. Several smoke pipes being conveyed are stacked in the smoke pipe conveying area 14. When the first synchronous belt 7 and the second synchronous belt 8 rotate, the several smoke pipes will move in the same direction.

[0022] In addition, to facilitate the rotation of the first driving synchronous pulley 3 and the second driving synchronous pulley 5, the output end of the drive motor 9 is connected to the reducer 12. The driving force generated by the drive motor 9 is then transmitted to the gear set 10 via the reducer 12. It should be noted that the gear set 10 consists of four gears, one of which is connected to the second driving synchronous pulley 5, and the last gear is connected to the first driving synchronous pulley 3. Therefore, when the gear set 10 rotates, the first driving synchronous pulley 3 and the second driving synchronous pulley 5 will rotate in opposite directions (see attached diagram). Figure 3 Taking the perspective of the first synchronous belt 7 as an example, the second active synchronous wheel 5 rotates clockwise, while the first active synchronous wheel 3 rotates counterclockwise. Therefore, the rotation directions of the first synchronous belt 7 and the second synchronous belt 8 are also opposite (the second synchronous belt 8 rotates clockwise, and the first synchronous belt 7 rotates counterclockwise). Thus, when the flue pipe in the flue pipe conveying area 14 needs to be conveyed, the flue pipe will move inside the flue pipe conveying area 14 by relying on the friction between the uppermost and lowermost layers of the flue pipe and the first synchronous belt 7 and the second synchronous belt 8.

[0023] In addition, both the upper and lower ends of the feed hopper 11 are open. The outlet of the feed hopper 11 corresponds to the conveying inlet of the first synchronous belt 7 and the second synchronous belt 8. Then, the flue pipe discharged from the lower opening of the feed hopper 11 will enter the flue pipe conveying area 14 for conveying. In addition, in order to slow down the descent speed of the flue pipe in the feed hopper 11, a flue pipe buffer 111 is symmetrically connected inside the feed hopper 11. The flue pipe buffer 111 has a semi-circular structure. In this way, the descent path of the flue pipe inside the feed hopper 11 is "S" shaped, which helps to buffer and slow down, thereby avoiding blockage of the inlet of the flue pipe conveying area 14.

[0024] An adaptive limiting module 13 is installed on the surface of the rear support plate 1 and the front support plate 2. The inlet of the adaptive limiting module 13 corresponds to the conveying outlet of the first synchronous belt 7 and the second synchronous belt 8. Specifically, the adaptive limiting module 13 includes an upper baffle plate 131 and a side baffle plate 132 installed on the front of the front support plate 2. The interior of the rear support plate 1 and the front support plate 2 are rotatably connected to a rotating seat 133. The front end of the rotating seat 133 extends to the front of the front support plate 2 and is connected to a movable baffle plate 134. The rear end of the rotating seat 133 extends to the back of the rear support plate 1 and is connected to a swing arm 135. A convex shaft 136 is connected to the back of the rear support plate 1. A spring 137 is connected between the bottom end of the convex shaft 136 and the swing arm 135. Limiting shafts 138 and gas springs 139 are installed on both sides of the back of the rear support plate 1 and within the rotation range of the top of the swing arm 135.

[0025] When the adaptive limit module 13 is in operation, when the flue pipe is conveyed to the conveying outlet of the first synchronous belt 7 and the second synchronous belt 8 (that is, the outlet of the flue pipe conveying area 14), in order to prevent the flue pipes from becoming loose (conversely, to maintain the compact structure between the flue pipes for easy final discharge), the adaptive limit module 13 is set up. In the structure of the adaptive limit module 13, the upper baffle 131, the side baffle 132, and the movable baffle 134 together form an approximately triangular area. In the structure of the triangular area, the top side is set as the inlet, which connects with the outlet of the flue pipe conveying area 14, and the bottom side is set as... The outlet, which is the final outlet of the flue pipe, will continuously squeeze the movable baffle 134 as it is conveyed to the outlet of the flue pipe conveying area 14. The movable baffle 134 will swing around the rotating seat 133 as the center. As the amount of flue pipe increases, the swing of the movable baffle 134 will also increase. However, due to the tension of the spring 137 at the bottom, the movable baffle 134 will always exert force on the flue pipe, thereby preventing the flue pipe from loosening. The swing of the movable baffle 134 also has an amplitude. Limiting shafts 138 and gas springs 139 are set on both sides of the swing amplitude to effectively prevent the movable baffle 134 from overstepping and failing.
