Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery and equipment in the tobacco industry, in particular to an automatic cleaning device for cigarette foam in a lower cigarette channel of a packaging machine. Background Art
[0002] In current cigarette manufacturing enterprises, YB25 soft box packaging machines are widely used in cigarette production. The cigarettes produced by the cigarette making machine pass through the storage tank bridge, and then enter the lower cigarette channel of the packaging machine through the cigarette conveying channel, and then are pushed into the cigarette mold box by the cigarette squeezer and the cigarette pusher before entering the packaging process.
[0003] In the actual production of cigarettes, after the cigarettes enter the packaging machine, they need to be conveyed downward from the lower cigarette channel under the action of gravity. During this process, a certain amount of tobacco foam will fall off due to the squeezing and collision between the cigarettes, and scatter and fall on the surface of the parts at the connection position of the upper conveying channel and the lower conveying channel, and accumulate on the surface of the parts. When the tobacco foam accumulates to a certain amount, it will overflow and fall into the lower conveying channel, thereby adhering to the surface of the cigarette, causing process quality problems such as cigarette foam.
[0004] In addition, before the cigarettes enter the cigarette squeezer process from the lower smoke channel, they need to pass through the cigarette clapper, which flattens the cigarettes so that they can enter the cigarette squeezer process accurately and smoothly. However, the cigarette clapper needs to keep moving back and forth to achieve the flattening of the cigarettes. During this process, when the cigarette clapper is opened, the cigarette foam will be brought out. Due to the effect of gravity, the brought-out cigarette foam will fall on the back plate of the cigarette clapper and accumulate at this position. When it accumulates to a certain amount, it will come into contact with the normal cigarettes moving downward, changing the original movement direction of the normal cigarettes, resulting in the generation of horizontally arranged cigarettes. The horizontally arranged cigarettes entering the cigarette squeezer process will cause the flue to be blocked, causing unnecessary downtime and failures.
[0005] Therefore, in the actual production process, the amount of tobacco foam accumulation will continue to increase with the continuous operation of the equipment. In the process of tobacco foam accumulation, tobacco foam will fall at any time or even fall off in clumps. These tobacco foams will fall into the cigarette equipment in the downstream process, resulting in process quality problems such as cigarette foam stuck in the cigarettes. Therefore, the staff must frequently stop the machine and then use cleaning tools to clean the tobacco foam accumulated on both sides of the conveying channel and the cigarette beater position. This not only increases the workload of the staff, but also reduces the continuous operation rate of the cigarette conveying equipment, causing a certain degree of waste of raw and auxiliary materials.
[0006] Based on this, the utility model provides an automatic smoke foam cleaning device for a smoke lowering channel which has a simple structure, is convenient to install and maintain, and has a low cost. Utility Model Content
[0007] In view of the above problems, the utility model provides an automatic cleaning device for smoke foam in the lower smoke channel, which uses a guide plate to collect the smoke foam that falls from the upper conveying channel of the cigarette and guide it to the smoke foam guide plate. The blowing holes on the surface of the gas pipe spray out the internal gas. With the regular reciprocating motion of the cigarette clapper, the lower position of the cigarette clapper and the smoke foam guide plate can be sprayed and cleaned in real time, so that the smoke foam moves obliquely downward along the smoke foam guide plate and falls to the smoke foam collection plate, thereby completing the automatic cleaning and collection and recovery of the smoke foam. The device has a simple structure and is easy to install and maintain. During the continuous operation of the cigarette conveying equipment, it can clean and collect the smoke foam generated during the cigarette conveying process in real time, with high work efficiency, and the staff can recover the smoke foam without stopping the machine, reducing the workload of the staff.

[0050] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0051] Example 1
[0052] As attached Figure 1 As shown, the automatic cleaning device for smoke foam in the lower smoke channel is mainly composed of a guide plate 1, a cigarette beater 2, an air pipe 3 and a cigarette guide plate 4. The guide plate 1 is installed at the connecting position of the upper cigarette conveying channel and the lower cigarette conveying channel, and the cigarette guide plate 4 is installed at the end position of the lower conveying channel. The smoke foam scattered from the upper conveying channel is guided by the guide plate 1 and falls onto the cigarette guide plate 4. The smoke foam generated by the reciprocating motion of the cigarette beater 2 can directly fall onto the cigarette guide plate 4. The gas sprayed from the air pipe 3 blows the smoke foam scattered on the cigarette guide plate 4 to the smoke foam collecting plate 41 located at the tip of the cigarette guide plate 4.
[0053] The present embodiment provides an automatic cleaning device for smoke foam in a lower smoke channel, comprising: a guide plate 1, a cigarette slapping plate 2, an air pipe 3 and a smoke foam guide plate 4, wherein the guide plate 1 is obliquely installed at the top position of the lower cigarette conveying channel, tightly fitting at the top of the lower conveying channel, and can effectively receive the smoke foam scattered inside the upper conveying channel. The cigarette slapping plate 2 is located at the rear position of the discharge end of the lower conveying channel, and the regular reciprocating motion is used to slap the cigarettes in real time, so that the cigarettes can enter the smoke squeezer process accurately and smoothly. The air pipe 3 is fixedly installed thereon, and follows the regular reciprocating motion of the cigarette slapping plate 2. The gas inside the air pipe 3 is blown out through the blowing hole 31, and is used to clean the smoke foam scattered on the smoke foam guide plate 4 in real time. The smoke foam guide plate 4 is arranged directly below the cigarette beater 2 and is installed at an angle. It has a V-shaped structure or a W-shaped structure. Its open end is fixedly connected to the bottom of the discharge end of the lower conveying channel to form a larger smoke foam receiving area. The pointed end collects and guides the smoke foam to fall into the smoke foam collection tray 41, thereby realizing automatic cleaning and collection and recovery of the smoke foam.
[0054] Specifically, as attached Figure 2-3As shown, the left and right sides of the guide plate 1 are semi-cylindrical structures, and the middle part is in an inverted V-shaped structure. The semi-cylindrical structure is fixedly connected at the end position by bolts, and the inverted V-shaped structure fits the back of the top of the lower cigarette conveying channel. When the cigarette is conveyed downward from the lower cigarette channel, a certain amount of cigarette foam will fall off due to the squeezing and collision between the cigarettes. The fallen cigarette foam can be guided along the fixed direction of the guide plate 1 and concentratedly fall on the cigarette foam guide plate 4 below.
[0055] As attached Figure 4-7 As shown, the cigarette clapper 2 includes: a fixing member 21 and a connecting member 22, wherein the fixing member 21 is an L-shaped structure, fixedly connected to the cigarette clapper 2 by bolts, and an opening is provided at the middle position thereof for passing through the gas pipe 3 and fixedly connected. The connecting member 22 is provided at the left and right ends of the cigarette clapper 2, and the cigarette clapper 2 is fixed to the two ends of the discharge end of the lower cigarette conveying channel in a movable and rotatable manner.
[0056] The gas pipe 3 includes: blowing holes 31, which are evenly arranged on the surface of the gas pipe 3. The blowing direction of the blowing holes 31 is at a certain inclination angle with the arrangement direction of the smoke foam guide plate 4 below. When the gas pipe 3 follows the cigarette beater 2 to make reciprocating motion, the gas blown out of the blowing holes 31 can blow the scattered smoke foam to the sharp corner position of the smoke foam guide plate 4 and drop it into the smoke foam collection tray 41.
[0057] The air guide tube 32 has one end spirally connected to the end of the air supply pipe 3, and the other end connected to the positive air pressure main channel of the packaging machine, so as to introduce the positive pressure air path of the packaging machine into the air supply pipe 3, thereby avoiding the addition of other energy sources and achieving energy saving.
[0058] The regulating valve 33 is arranged at the connection between the air guide pipe 32 and the air delivery pipe 3, and is used to control and adjust the air flow rate of the blowing hole 31, so that the staff can control and adjust the air flow rate according to the actual working requirements of the smoke lowering channel.
[0059] The adjustable connection assembly 34 is arranged at the end of the gas delivery pipe 3 and is connected to the rotating part 5 of the packaging machine through the adjustable connection assembly 34. The adjustable connection assembly 34 includes a joint 341 and a pin 342. One end of the joint 341 is provided with a threaded hole, which is used to connect the rotating part 5 of the packaging machine. The other end is a cylindrical shape with a threaded through hole, which is used in conjunction with the threaded end of the pin 342. The hexagonal nut provided at the threaded end of the pin 342 is used to flexibly adjust the thread length of the pin 342 inserted into the joint 341 and to lock the pin 342 when it is in place. The other end of the pin 342 is a cylindrical shape with a through hole, which is used to connect the gas delivery pipe 3.
[0060] The smoke foam guide plate 4 is arranged directly below the cigarette clapper 2 and is installed obliquely. It is V-shaped and includes a smoke foam collecting plate 41 and a placing tray 42. The placing tray 42 is fixedly connected to the bottom of the pointed end of the smoke foam guide plate 4 with bolts and is used to flexibly place the smoke foam collecting plate 41 so that the staff can replace or repair the smoke foam collecting plate 41 in real time. A movable handle is provided on the end surface of the smoke foam collecting plate 41 for quickly installing or removing the smoke foam collecting plate 41.
[0061] Example 2
[0062] As attached Figure 8 As shown, the shape of the smoke guide plate 4 can be set to a W-shaped structure, with two sharp corners symmetrically provided and arranged at the side, so that the smoke is diverted to both sides and falls into the smoke collection tray 41 below. In a narrow and crowded environment, the staff can replace the smoke collection tray 41 more quickly from the side, and a new smoke collection tray 41 is added, which reduces the frequency and number of times the staff replaces the smoke collection tray 41, and reduces the work intensity of the staff.
[0063] Finally, it should be noted that the above has been combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the utility model, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, the connection relationship mentioned in the text does not only refer to the direct connection of components, but refers to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.
