Detailed implementation manners

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] An embodiment of the present invention provides a mechanical device for preparing cigarette paper tubes, and the structure is as Figure 1 shown. A mechanical device for preparing cigarette paper tubes includes a blanking device 1, an intermittent cigarette conveyor belt 4, a first driving device 11, a sample gripper 6, a sensor 15, a compressed air blowing pipe 7, and a control unit (not shown in the figure). The blanking device 1 has a material leakage port 14, and the shape and size of the material leakage port 14 are adapted to the shape and size of the cigarette 3, so that only one cigarette 3 can pass through the material leakage port 14 each time, and the blanking device 1 is used to hold the cigarette 3; a plurality of cigarette grids 13 are provided on the intermittent cigarette conveyor belt 4, d < the width of the cigarette grid 13 < 2d, where d is the diameter of the cigarette 3, so that each cigarette grid 13 can only hold one cigarette 3; the intermittent cigarette conveyor belt 4 is located below the blanking device 1; at the same time, d < the distance from the material leakage port 14 to the bottom of the cigarette grid 13 < 2d, where d is the diameter of the cigarette 3, so that during the process of the intermittent cigarette conveyor belt 4 transporting the cigarette 3 forward, only one cigarette 3 falls from the material leakage port 14 into the cigarette grid 13 each time; the first driving device 11 is used to drive the intermittent cigarette conveyor belt 4 to rotate; the sample gripper 6 is arranged above the intermittent cigarette conveyor belt 4 and is used to clamp and fix the cigarette 3; the sensor 15 is arranged on the sample gripper 6 and is used to sense whether there is a cigarette 3 passing below the sample gripper 6, and the sensor 15 can be an infrared sensor or a microwave sensor; the compressed air blowing pipe 7 is arranged beside the sample gripper 6 and is used to blow air on the filter tip of the cigarette 3 clamped and fixed by the sample gripper 6; the control unit receives the sensing signal of the sensor 15 and controls the actions of the sample gripper 6 and the compressed air blowing pipe 7; the sensor 15, the compressed air blowing pipe 7, and the control unit are electrically connected. It should be understood that the sample gripper 6 and the compressed air blowing pipe 7 are also equipped with support devices for some related equipment, Figure 1 which are not fully shown in the figure.

[0028] In use, the cigarette 3 is placed into the blanking device 1. After starting the intermittent cigarette conveyor belt 4, the cigarette 3 successively falls into the cigarette cell 13 of the intermittent cigarette conveyor belt 4 from the material leakage opening 14 of the blanking device 1. The intermittent cigarette conveyor belt 4 transports the cigarette 3 to the sample clamping device 6. After the inductor 15 senses that the cigarette 3 is in place, the inductor 15 sends an induction signal to the control unit. The control unit controls the sample clamping device 6 to move downward to clamp the filter tip of the cigarette 3, fixing the cigarette 3. Then, the control unit controls the compressed air blowing pipe 7 to approach and align with the filter tip of the cigarette 3 in close contact, and blows out the tobacco shreds. After the tobacco shreds are blown out, the control unit controls the sample clamping device 6 and the compressed air blowing pipe 7 to return to their original positions, preparing for the clamping and purging operation of the next cigarette 3.

[0029] A mechanical device for preparing cigarette paper tubes according to the present invention uses the blanking device 1 to store the cigarette 3, the intermittent cigarette conveyor belt 4 to transport the cigarette 3 and fix the position of the cigarette 3, the sample clamping device 6 to clamp the filter tip of the cigarette 3, and the compressed air blowing pipe 7 to align with the filter tip and blow out the tobacco shreds. The mechanical device for preparing cigarette paper tubes according to the present invention changes the current situation that cigarette paper tubes can only be prepared manually, realizing the automation of cigarette paper tube preparation; and the mechanical device for preparing cigarette paper tubes according to the present invention has a simple structure, is convenient to operate, improves the preparation efficiency of cigarette paper tubes, and saves more time and labor.

[0030] Preferably, the material leakage opening 14 and the cigarette cell 13 are arranged in a staggered manner; after the cigarette 3 falls from the material leakage opening 14 into the cigarette cell 13, the filter tip portion of the cigarette 3 can protrude outside the cigarette cell 13. In this way, due to the staggered arrangement, the cigarette 3 cannot completely fall into the interior of the cigarette cell 13 after falling from the blanking device 1, and the filter tip portion of the cigarette 3 protrudes outside the cigarette cell 13, facilitating the sample clamping device 6 to clamp and fix the filter tip portion of the cigarette 3.

[0031] Preferably, the mechanical device for preparing cigarette paper tubes of the present invention further comprises a cigarette pressing device, which is arranged above the interspaced cigarette conveyor belt 4 and is used to press the cigarettes 3 conveyed on the interspaced cigarette conveyor belt 4. The depth of the cigarette grid 13 is <d,且1.1d<烟支格的宽度<1.3d,d为烟支3的直径,这样可以使得烟支3有一部分裸露在烟支格13的外部,便于烟支按压装置对烟支3进行按压。烟支按压装置包括传动履带5、和第二驱动装置12,第二驱动装置12用于驱动传动履带5转动。当1.1d<烟支格的宽度<1.3d时,在传动履带5的转动带动下,烟支3会很容易地在烟支格13内转动,使得传动履带5可以对烟支3的外周进行均匀地按压,可以提高烟支3内烟丝的松散程度,更利于后续过程中烟丝的吹出操作。可将烟支格13的内壁打磨至光滑状,更利于烟支3在烟支格13内转动。烟支按压装置对烟支3进行按压后,可以对包覆在烟支3内的烟丝进行松散,经过松散处理后的烟丝在后续的压缩空气吹管7的吹扫下更容易被吹出,这样可以使用较低压力的压缩空气对烟支3的过滤嘴部分进行吹扫,可以避免卷烟纸筒制备过程中卷烟纸经常被吹破,或嘴棒从过滤嘴中吹出的现象,减少烟支3的浪费。同时,滚动的传动履带5对烟支3的外周进行均匀按压,可以避免烟支3的外包装纸磨破、损坏。应该理烟支按压装置还配备有一些相关设备的支撑装置, Figure 1 Not fully shown.

[0032] More preferably, the transmission track 5 is a rubber track. The rubber transmission track has greater friction with the cigarettes 3, which can better drive the cigarettes 3 to rotate evenly in the cigarette grid 13, and then evenly press the outer periphery of the cigarettes 3.

[0033] More preferably, 1.1d<the distance from the leakage port 14 to the bottom of the cigarette grid 13≤1.5d, 1 / 2d≤the depth of the cigarette grid 13 <d,d为烟支3的直径。这样可以使得每次从漏料口14中刚好下落一支烟支3到烟支格13中,且烟支格13内的烟支3在传动履带5的带动下,均匀转动。例如,单只烟支3的直径为8mm,过滤嘴部分长为3cm时,可以将烟支格13的宽度设置为1cm,烟支格13的深度设置为5mm,漏料口14到烟支格13底部的距离设置为9mm,漏料口14与烟支格13错位设置3cm,使得烟支3的过滤嘴部分突出在烟支格13的外部。

[0034] Preferably, the upper part of the blanking device 1 is in the shape of a cabinet, and a cabinet door 2 is provided on the blanking device 1. When in use, the cabinet door 2 of the blanking device 1 is opened, and the cigarette sticks 3 are placed in a staggered manner from bottom to top in sequence. After the cigarette sticks 3 are placed, the cabinet door 2 of the blanking device 1 is closed again. In this way, the cigarette sticks 3 are stored inside the blanking device 1, and the filter tip ends of the cigarette sticks 3 abut against the inner side surface of the cabinet door 2 after being placed, so that the cigarette sticks 3 can be kept neat at their original placement positions inside the blanking device 1.

[0035] Preferably, a mechanical device for preparing cigarette paper tubes according to the present invention further includes a tobacco shred collecting box 8, a ramp 9, and a paper tube collecting box 10. One end of the ramp 9 is smoothly abutted against one end of the spaced cigarette stick conveyor belt 4, and the other end of the ramp 9 is abutted against the entrance of the paper tube collecting box 10. The tobacco shred collecting box 8 is used for collecting the blown tobacco shreds. In this way, the compressed air blowing pipe 7 blows the tobacco shreds out and drops them into the tobacco shred collecting box 8, and the spaced cigarette stick conveyor belt 4 transports the empty paper tubes to the ramp 9, and the empty paper tubes fall into the paper tube collecting box 10 through the ramp 9.

[0036] The present invention is not limited to the above specific embodiments, and various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made based on the technical essence of the present invention to the above embodiments shall be included within the protection scope of the present invention.
