Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production and processing, in particular to a cigarette conveying channel buffer device. Background Art

[0002] In the production process of cigarettes, the cigarette carton packaging machine is used to pack cigarettes into cigarette cartons. The cigarette cartons are output from the cigarette carton packaging machine's outlet flipping device and transported to the next process, such as testing, packing, etc.

[0003] The existing cigarette strip separator of the conveying channel of the cartoning machine is mainly composed of two pairs of rubber rollers and motors. The lower rubber rollers on both sides are driven by motors and fixed on the brackets. The main function is to separate the cigarette strips that are continuously close to each other in the conveying channel so that the cigarette strips will not be kicked by mistake when entering the cigarette strip appearance detector. The position distance adjustment between the upper and lower rubber rollers is a key factor in the performance of the separator. If the distance is too large, the cigarette strips will not be separated due to the lack of sufficient restraint force when passing through. The two unseparated cigarette strips will be removed when entering the strip box appearance inspection, and the cigarette strips will collide during the removal, causing quality problems and reducing the production efficiency of the machine. If the distance is too small, the cigarette strips will be deformed or damaged due to excessive squeezing. Therefore, it is necessary to properly adjust the position and distance of the separator rubber rollers to ensure that the cigarette strips are separated without causing cigarette strip deformation when the upstream machine is supplying cigarettes normally or the collector is releasing cigarettes.

[0004] When the collector releases cigarettes, the continuous intake of cigarettes in the conveying channel is large, and the force of the cigarettes squeezing forward is greater than when the machine is operating normally. The existing separator cannot play a good separation role. The distance between the two pairs of rubber rollers of the separator is too close, which easily causes the cigarettes to be wrinkled. If the distance is too large, the separation effect is not good. Continuous cigarettes passing through the cigarette detection device will cause accidental kicking and collision. Therefore, a cigarette conveying channel buffer device is urgently needed to solve the above problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] like Figure 1-Figure 5As shown, in this embodiment, a cigarette conveying channel buffer device includes a fixed frame 1, a driving member 2, a buffer member 3 and a guide assembly 4. Among them, the fixed frame 1 is installed on the conveying channel, the driving member 2 is arranged on the fixed frame 1, the buffer member 3 is located above the conveying channel, and the buffer member 3 is detachably connected to the output end of the driving member 2, and the buffer member 3 is used to fit and slow down the cigarette in the conveying channel. The guide assembly 4 includes a guide rod 41 and an elastic member 42, the guide rod 41 is slidably inserted into the through hole of the fixed frame 1 and connected to the buffer member 3, the elastic member 42 is sleeved on the guide rod 41, and the two ends of the elastic member 42 are respectively connected to the end of the guide rod 41 and the fixed frame 1, and the guide rod 41 is detachably connected to the buffer member 3. Specifically, the fixed frame 1 is an inverted U-shaped structure, the fixed frame 1 is installed on the two side walls of the conveying channel, the driving member 2 is installed at the lower part of the fixed frame 1, the output end of the driving member 2 is connected to the buffer member 3, and the buffer member 3 is located above the conveying channel. Under the driving action of the driving member 2 , the buffer member 3 can gradually approach the conveying channel. One end of the guide rod 41 is connected to the buffer member 3 , and the other end is slidably inserted into the through hole of the fixing frame 1 . The elastic member 42 is sleeved on the guide rod 41 .

[0040] The working process of the buffer device is as follows: in the initial state, the buffer 3 is suspended above the conveying channel and separated from the cigarettes. When the collector needs to release the cigarettes, the driving member 2 is started, and the driving member 2 drives the buffer 3 to overcome the elastic member 42 and gradually approach the conveying channel. The elastic member 42 is compressed. At the same time, the guide rod 41 slides relative to the fixed frame 1, and the guide rod 41 and the buffer 3 move downward synchronously until the buffer 3 is close to the surface of the cigarette and generates friction. The friction between the buffer 3 and the cigarette not only slows down the conveying speed of the cigarette, ensuring that the cigarette reaches a suitable speed before entering the separation process, and plays the effect of preliminary separation of the cigarettes, but also reduces the collision and stacking between the cigarettes. This helps the separator to more accurately identify and separate each cigarette, and improves the separation efficiency and accuracy. The guide rod 41 has a certain guiding effect, preventing the buffer 3 from offsetting and reducing the contact area with the cigarette, thereby reducing the friction between the buffer 3 and the cigarette and affecting the mitigation effect. When it is not necessary to release cigarettes, the driving member 2 stops, and under the elastic action of the elastic member 42, the guide rod 41 slides upward relative to the fixed frame 1, and drives the buffer member 3 to move synchronously to the initial position until the elastic member 42 returns to its original state, thereby avoiding interference with the normal operation of the production line. The driving member 2 and the guide rod 41 are both detachably connected to the buffer member 3, which is convenient for quick replacement of the buffer member 3 and easy maintenance. The cigarette conveying channel buffer device is mainly used before the appearance inspection of the cigarette conveying channel box of the cartoning machine, and can also be used on other conveying channels that require buffering and separation. Optionally, to ensure that the device does not cause harm to the human body during operation, measures such as installing a protective cover and setting an emergency stop button are required.

[0041] Further, continue to refer to Figure 1-Figure 5, the outer circumference of one end of the guide rod 41 is provided with an external thread, the buffer 3 is provided with a first threaded hole 31, and the guide rod 41 is threadedly connected to the buffer 3. The outer circumference of the output end of the driving member 2 is provided with an external thread, and the buffer 3 is also provided with a second threaded hole 32, and the driving member 2 is threadedly connected to the buffer 3. Specifically, the guide rod 41 is slidably matched with the through hole of the fixed frame 1, and the guide rod 41 is rotated counterclockwise, and the guide rod 41 rotates relative to the fixed frame 1, and the guide rod 41 is threadedly matched with the first threaded hole 31 of the buffer 3, that is, the guide rod 41 rotates and separates relative to the buffer 3, and the buffer 3 is not restricted by the guide rod 41. The buffer 3 is rotated, and the second threaded hole 32 of the buffer 3 is threadedly matched with the output end of the driving member 2, that is, the buffer 3 rotates and separates relative to the driving member 2, and the buffer 3 can be disassembled, which is convenient for maintenance and replacement.

[0042] Further, continue to refer to Figure 1-Figure 5 , a stopper 5 is convexly provided at the other end of the guide rod 41, and the stopper 5 is connected to the elastic member 42. Specifically, the stopper 5 is integrally formed with one end of the guide rod 41, one end of the elastic member 42 abuts against the stopper 5, and the other end abuts against the end surface of the fixing frame 1. When the guide rod 41 and the buffer member 3 move synchronously toward the conveying channel, the elastic member 42 is compressed, and the stopper 5 plays a role of limiting, preventing the guide rod 41 from being separated from the through hole of the fixing seat and becoming ineffective.

[0043] Further, continue to refer to Figure 1-Figure 5 There are two guide assemblies 4, and along the length direction of the buffer 3, the two guide assemblies 4 are spaced apart on both sides of the driving member 2. Specifically, the two guide rods 41 are respectively penetrated through the corresponding through holes of the fixing frame 1 and connected to the two ends of the buffer 3. During the movement of the buffer 3, the two guide rods 41 and the output end of the driving member 2 can make the buffer 3 close to the surface of the cigarette in the conveying channel. The two guide rods 41 not only play a guiding role, but also can ensure that the end surface of the buffer 3 is completely in contact with the cigarette, thereby fully ensuring the friction effect between the cigarette and the buffer 3.

[0044] Further, continue to refer to Figure 1-Figure 5The buffer device for the cigarette conveying channel also includes a first connecting member. The fixed frame 1 includes two support seats 11 and a crossbeam 12. The two support seats 11 are respectively arranged at the two ends of the crossbeam 12. The support seat 11 is provided with a mounting hole. The crossbeam 12 is provided with a connecting hole 121. The first connecting member passes through the connecting hole 121 and is connected to the mounting hole. Specifically, the crossbeam 12 and the support seat 11 are both made of stainless steel. The first connecting member is a bolt. The side wall of the conveying channel is provided with a screw hole. The two support seats 11 are respectively fixed by screws through the screw holes of the conveying channel. Then, the crossbeam 12 passes through the connecting hole 121 of the crossbeam 12 through the first connecting member and is fixed to the mounting hole of the support seat 11. It is necessary to ensure that the connection between the two support seats 11 is firm to support the weight of the horizontally long strip object and the force generated when it moves.

[0045] Further, continue to refer to Figure 1-Figure 5 , the buffer 3 is a brush. Specifically, the brush is made of a flexible material and is in flexible contact with the surface of the cigarette strip, which will not cause the cigarette strip to wrinkle, reducing the impact of downtime caused by wrinkling of the cigarette strip, thereby improving production efficiency and cigarette strip quality. At the same time, due to the softness of the brush, it does not affect the quality of the cigarette strip, and the precision requirement for the height of the brush is lower than the distance between the rubber roller position on the separator. The influence of the height difference between the soft and hard box cigarette strips can be ignored, reducing maintenance work and improving production efficiency. Optionally, the buffer 3 can also be a sponge or cotton cloth, both of which can have the effect of slowing down the cigarette strip.

[0046] Further, continue to refer to Figure 1-Figure 5 The buffer device for the cigarette conveying channel also includes a second connecting member. The support seat 11 includes a supporting portion 111 and a mounting portion 112 connected to the supporting portion 111. The mounting portion 112 is an L-shaped structure. The mounting portion 112 is provided with a waist-shaped hole 6. The second connecting member passes through the waist-shaped hole 6 and is connected to the side wall of the conveying channel. Specifically, the second connecting member is a bolt. The support seat 11 passes through the waist-shaped hole 6 of the mounting portion 112 through the second connecting member and is fixedly connected to the side wall of the conveying channel, so that the fixing frame 1 is fixed on the conveying channel. The initial height of the fixing seat and the buffer 3 can be adjusted through the waist-shaped holes 6 of the two support seats 11 to adapt to conveying channels of different depths, ensuring that the buffer 3 can be close to the surface of the cigarette.

[0047] Further, continue to refer to Figure 1-Figure 5 There are multiple waist-shaped holes 6, and along the conveying direction of the cigarette in the conveying channel, multiple waist-shaped holes 6 are arranged at intervals. Specifically, multiple connecting pieces pass through the corresponding waist-shaped holes 6 and are fixed to the side walls of the conveying channel, so that the installation is more firm and not easy to loosen.

[0048] Further, continue to refer to Figure 1-Figure 5The support seat 11 further includes a reinforcing portion 113. The mounting portion 112 has a first end face and a second end face, the first end face and the second end face are vertically arranged, and the reinforcing portion 113 is fixedly connected to the first end face and the second end face. Specifically, the reinforcing portion 113 is a reinforcing rib, and the support seat 11 plays a certain supporting role. When the mounting portion 112 of the support seat 11 is fixedly connected to the side wall of the conveying channel, the reinforcing rib can strengthen the structural strength of the mounting portion 112 and extend the service life.
