DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0016] A smoke discharging device of the present invention is mainly used in the preparation of cigars, and is used in conjunction with a cigar wrapping machine 8 to assist in the transportation and transfer of the produced cigars. The cigar wrapping machine 8 is mainly used to process cigar wrappers, complete the cutting and wrapping of cigar wrappers, and deliver the rolled cigars. However, during the delivery process of cigars, due to the vibration of the equipment or the height difference and instability at the outlet, the placement angle and spacing of the cigars on the conveying equipment cannot remain consistent, which affects subsequent packaging production and other processes. The smoke discharging device of the present invention is mainly used to receive and convey the cigars delivered by the cigar wrapping machine 8, and to adjust the placement posture and spacing of the cigars during the delivery process, so that the cigars remain neatly arranged and enter the next process.

[0017] Specifically, the main structure and working principle of the cigar wrapping machine 8 can be referred to many documents represented by the application number CN112641128A. Among them, due to the structure and process design of the cigar wrapping machine 8 itself, the processed cigars are delivered one by one from the cigar wrapping machine 8, so there is a time interval between two adjacent cigars delivered by the cigar wrapping machine 8 and falling on the smoke outlet device of the present invention.

[0018] A smoke outlet device of the present invention, such as Figure 1-3 As shown, it includes a conveyor belt 1 for conveying cigarettes, a baffle 2 arranged on the belt surface of the conveyor belt 1 perpendicular to the conveying direction of the conveyor belt 1, and a transmission assembly, the transmission assembly drives the baffle 2 to reciprocate so that the cigarettes are moved by the baffle 2 to change the transportation posture of the cigarettes on the conveyor belt 1. Specifically, the conveyor belt 1 is used to receive the cigars transmitted by the cigar skinning machine 8 and drive the cigarettes to move along the conveying direction; the baffle 2 reciprocates in a plane perpendicular to the belt surface direction of the conveyor belt 1. When the cigarette approaches the baffle 2, the baffle 2 is located near the belt surface of the conveyor belt 1, and the cigarette is stopped by the baffle 2 until the cigarette is aligned with the baffle 2 as a whole under the friction of the conveyor belt 1 and is aligned, and then the baffle 2 rotates so that a gap appears between the baffle 2 and the belt surface of the conveyor belt 1, and the aligned cigarettes continue to be transported forward through the gap between the baffle 2 and the conveyor belt 1, and the subsequent cigarettes are stopped by the baffle 2 one by one and pass through the baffle, so that the transported cigarettes are arranged neatly one by one.

[0019] In order to make the smoke outlet device of the present invention more compact, reduce the number of power elements, and reduce the cost, in this embodiment, the conveyor belt 1 and the baffle 2 are respectively connected to the same power source 7 through a transmission assembly. The power source 7 needs to drive the conveyor belt 1 to move in one direction to keep the cigarettes transported forward; and for the baffle 2, the power source 7 needs to drive the baffle 2 to move back and forth so that the baffle 2 stops the cigarettes or lifts up. Therefore, the transmission assembly needs to coordinate the power transmission mode of the power source 7 to ensure that the power source 7 can drive the baffle 2 to move back and forth while driving the conveyor belt 1 to move in one direction.

[0020] In this embodiment, the transmission assembly includes a main shaft 3 driven by a power source 7, and the main shaft 3 reciprocates under the drive of the power source. The conveyor belt 1 includes a belt 11 for receiving cigarettes, and a driving wheel 12 for driving the belt 11 to move. The driving wheel 12 is connected to the main shaft 3 through a one-way bearing (not shown in the figure), and the main shaft 3 rotates to drive the driving wheel 12 to drive the belt 11 to move. Under the action of the one-way bearing, when the main shaft 3 rotates forward, the driving wheel 12 of the conveyor belt 1 can rotate with the main shaft 3, driving the belt 11 to move in the conveying direction. When the main shaft 3 reverses, the driving wheel 12 of the conveyor belt 1 stops rotating, and the belt 11 remains stationary to ensure that the transportation direction of the conveyor belt 1 is always consistent. Among them, the one-way bearing is a commonly used mechanical component, and its structure and working principle are not repeated here.

[0021] In this embodiment, the baffle 2 is a long thin plate, which is perpendicular to the surface of the belt 11 and is arranged above the belt 11. The transmission assembly also includes a swing rod 5 connecting the baffle 2 and the main shaft 3. The baffle 2 is fixedly connected to the swing rod 5, and the swing rod 5 reciprocates synchronously with the main shaft 3, so that the baffle 2 approaches or moves away from the surface of the belt 11 with the rotation of the main shaft 3. When the baffle 2 approaches the surface of the belt 11, the cigarettes are stopped by the baffle 2 and aligned with the baffle, thereby changing the placement of the cigarettes on the belt 11; when the baffle 2 is away from the surface of the belt 11, the neatly placed cigarettes can pass through the gap between the baffle 2 and the belt 11 and continue to be transported forward over the baffle 2.

[0022] The specific working process of the smoke discharging device of the present invention is as follows: the processed cigarettes are transmitted from the cigar wrapping machine 8 and roll toward the conveyor belt 1. At this time, the main shaft 3 reverses, and the baffle 2 is driven to move toward the surface of the belt 11 close to the conveyor belt 1. The conveyor belt 1 remains stationary under the action of the one-way bearing until the cigarette rolls to the position of the baffle 2 and remains aligned with the baffle 2; then the main shaft 3 rotates forward, and the baffle 2 is driven to move away from the conveyor belt 1. A gap appears between the baffle 2 and the surface of the belt 11 of the conveyor belt 1. At the same time, the conveyor belt 1 starts to move in the transportation direction, driving the cigarette whose placement posture has been corrected to pass over the baffle 2, thereby completing the adjustment of the transportation posture of a cigarette.

[0023] In this embodiment, if Figure 3As shown, the belt surface of the conveyor belt 1 is slightly lower than the smoke outlet of the cigar wrapping machine 8. The conveyor belt 1 and the cigar wrapping machine 8 are connected by an inclined slide plate 9. The baffle 2 is arranged at the end of the conveyor belt 1 close to the smoke outlet of the cigar wrapping machine 8. The cigarettes are transmitted from the smoke outlet of the cigar wrapping machine 8 and roll from the slide plate 9 to the conveyor belt 1 under the action of gravity until they abut against the baffle 2.

[0024] In this embodiment, the conveyor belt 1 further comprises a tensioning wheel 13 for tensioning the belt 11 to prevent the belt 11 from slipping. A one-way bearing is also arranged on the rotating shaft of the tensioning wheel 13.

[0025] In this embodiment, in order to ensure the coordination of the movement of the baffle 2 and the conveyor belt 1, it is necessary to debug the conveying speed of the conveyor belt 1 and the rotation speed of the baffle 2. Among them, if the swing rod 5 is directly fixedly connected to the main shaft 3, the rotation speed of the baffle 2 is consistent with the rotation speed of the main shaft 3. At this time, the conveying speed of the conveyor belt 1 can only be adjusted by adjusting the diameter of the driving wheel 12 of the conveyor belt 1 to meet the coordination relationship requirements of the movement speed of the conveyor belt 1 and the baffle 2. The debugging is relatively cumbersome when changing the parameters. Therefore, a transmission assembly of a smoke outlet device of the present invention is also provided with a cam 4 fixedly connected to the main shaft 3, and the swing rod 5 is installed on the frame 6 of the smoke outlet device of the present invention, and is rotatably connected to the frame 6, and one end is fixedly connected to the baffle 2, and the other end is abutted against the cam 4. The rotation of the main shaft 3 drives the cam 4 to rotate synchronously, so that the position of the outer contour of the cam 4 abutting against the swing rod 5 changes, thereby driving the swing rod 5 to rotate. At this time, the rotation speed of the swing rod 5 can be adjusted by changing the shape parameter setting of the outer contour of the cam 4, thereby realizing the debugging of the rotation speed of the baffle 2.

[0026] In this embodiment, the swing rod 5 includes a side plane 51 that abuts against the cam 4, and the outer contour of the cam 4 includes a straight segment 41 and an arc segment 42, and the straight segment 41 can fit against the side plane 51. Specifically, there are two straight segments 41, which are arranged on both sides of the arc segment 42. In the initial state, the arc segment 42 abuts against the side plane 51 of the swing rod 5. When the main shaft 3 starts to rotate, the cam 4 rotates through a certain angle together with the main shaft 3, so that the arc segment 42 rotates away from the side plane 51 of the swing rod 5, and one of the straight segments 41 of the cam 4 gradually approaches the side plane 51 until it fits against the side plane 51. At this time, the main shaft 3 drives the cam 4 to continue to rotate, and the straight segment 41 of the cam 4 applies pressure to the side plane 51 of the swing rod 5, so that the swing rod 5 rotates around the connection point between the swing rod 5 and the frame 6; when the main shaft 3 rotates in the opposite direction until the other straight segment 41 of the cam 4 abuts against the side plane 51 of the swing rod 5, the swing rod 5 can rotate in the opposite direction. Among them, by changing the setting angle of the straight section 41 of the cam 4 and the angle between the side plane 51 of the rocker arm 5 and the horizontal plane, the rotation speed of the rocker arm 5 and the pause interval of the rocker arm 5 can be adjusted to adapt to the smoke output speed of the cigar wrapping machine 8, while ensuring the consistency of the arrangement spacing between cigarettes.

[0027] In this embodiment, the power source 7 is a motor, and the output shaft of the motor is connected to the main shaft 3 through a reducer. The reciprocating rotation of the output shaft of the motor drives the main shaft 3 to reciprocate.

[0028] As another implementation of this embodiment, the power source is a motor, and the output shaft of the motor is connected to the main shaft 3 through a cam connecting rod mechanism (not shown in the figure). The output shaft of the motor rotates unidirectionally, and the cam connecting rod mechanism converts the unidirectional rotation of the motor into the reciprocating rotation of the main shaft 3. Specifically, the cam connecting rod mechanism includes a first cam fixedly connected to the output shaft of the motor, a connecting block fixedly connected to the main shaft 3, and a connecting rod connected to the first connecting block at one end and abutted against the first cam at the other end. The first cam rotates under the drive of the motor, so that the connecting rod abutting against the first cam moves up and down, thereby driving the connecting block to swing left and right, that is, realizing the reciprocating rotation of the main shaft 3.
