Description

Technical Field

[0001] The utility model relates to the technical field of an automatic cigarette cut - filler boxing system, and particularly relates to a film feeding component of an automatic bag - sleeving machine for formulated cigarette cut - filler. Background Art

[0002] At present, in a series of numerous processes such as carton opening, carton bag - sleeving, cigarette cut - filler boxing, weighing, plastic bag sealing, and carton sealing in a cigarette factory, manual operation is mainly adopted. The economic benefit of a cigarette factory depends on the production volume, so production efficiency is very important for a cigarette factory. Manual operations such as carton opening, bag - sleeving, boxing, and sealing have low technical content and are time - consuming and labor - intensive. The automatic cigarette cut - filler bag - sleeving and sealing system is a technological process to replace manual operations such as carton opening, bag - sleeving, boxing, and sealing.

[0003] In the automatic cigarette cut - filler bag - sleeving and sealing system, the film feeding component of the bag supply system of the bag - sleeving machine is mainly used to supply packaging film (i.e., plastic film or other types of packaging materials). During the film feeding process, a roll of continuous plastic film is usually used, and this plastic film forms a tubular structure inside the bag - sleeving machine. This tubular plastic film is continuously input through the film feeding component and then undergoes a series of processes of cutting and heat - sealing to finally form individual packaging bags.

[0004] At present, the film feeding component of the automatic bag - sleeving machine for formulated cigarette cut - filler lacks the function of pre - stratifying the plastic film. Since the plastic film may be tightly stacked together during winding, or be squeezed during transportation and storage, the inner walls of its tubular structure are usually closely attached to each other. The excessive adhesion between the inner walls of the plastic film will lead to poor bag - opening effect in the subsequent process, affecting the bag - sleeving quality. Secondly, the film storage capacity of the film feeding component of the current automatic bag - sleeving machine for formulated cigarette cut - filler is poor, and the plastic film is prone to slipping between the conveying rollers during the film feeding process, resulting in displacement and folding of the plastic film, which hinders the continuous supply of plastic bags.

[0037] Embodiment 1:

[0038] Please refer to Figure 1-7 , this embodiment provides a film feeding component for an automatic bagging machine for formulated cut tobacco. The main function of the film feeding component is to supply the plastic film 211 for the automatic bagging machine for formulated cut tobacco. The film feeding component of this embodiment includes a mounting frame 10, and the mounting frame 10 is mainly composed of several profiles and sheet metal materials. The mounting frame 10 of this embodiment consists of several independent structural frames, which are not distinguished here, and their functions are to provide support and installation basis for each component, and the film feeding component is installed on the bagging machine frame through the mounting frame 10.

[0039] A film storage device 20, a film opening device 30 and a film guiding device 40 are sequentially arranged on the mounting frame 10;

[0040] Film storage device 20, the film storage device 20 is fixed to the bottom of the mounting frame 10, the film storage device 20 includes a film storage roller 21, and a roll of plastic film 211 to be conveyed is sleeved on the film storage roller 21;

[0041] Film opening device 30, the film opening device 30 is arranged between the film storage device 20 and the film guiding device 40, the film opening device 30 includes a film opening partition rod 31, and the film opening partition rod 31 is used to be placed inside the plastic film 211 to separate the inner layer of the plastic film 211;

[0042] The film guiding device 40 includes a film guiding driving member 41, a conveying and guiding roller 42, a film pressing assembly 43 and a film guiding plate 44; the film guiding driving member 41 is a servo motor, the film guiding driving member 41 has an output shaft, and the output shaft of the film guiding driving member 41 is connected to the conveying and guiding roller 42 through a synchronous pulley transmission assembly; the film pressing assembly 43 is arranged on one side of the conveying and guiding roller 42, the film pressing assembly 43 is used to press the plastic film 211 against the surface of the conveying and guiding roller 42, and the film guiding plate 44 is arranged on one side of the film outlet direction of the conveying and guiding roller 42; the conveying and guiding roller 42 is driven by the film guiding driving member 41 to rotate so that the plastic film 211 is sent to a preset area through the film guiding plate 44.

[0043] Based on the above structure, during the use process, a roll of plastic film 211 is sleeved on the film storage roller 21, and the film opening partition rod 31 is placed inside the plastic film 211. Through the blocking effect of the film opening partition rod 31 between the inner walls of the plastic film 211, the layers of the plastic film 211 that are closely attached together are separated; after being stratified by the film opening partition rod 31, the plastic film 211 is wound around the circumferential direction of the conveying guide roller 42. The pressing film assembly 43 provides pressure to press the plastic film 211 against the surface of the conveying guide roller 42, increasing the friction between the plastic film 211 and the surface of the conveying guide roller 42. The pressing film assembly 43 ensures that the plastic film 211 does not slip during the conveying process; the film guiding driving part 41 is started, and the film guiding driving part 41 provides power to drive the conveying guide roller 42 to rotate, and the plastic film 211 is sent to a preset area through the film guiding plate 44, so as to realize that the film layers of the plastic film 211 can be independently and smoothly conveyed to the subsequent processing stage without interruption. Through the pre-stratification of the plastic film 211 during the film feeding process, the subsequent bag opening efficiency of the bagging machine is greatly improved, thereby improving the success rate of bagging of the bagging machine.

[0044] Specifically, the film storage device 20 of this embodiment further includes a film feeding driving part 22, a film feeding driving roller 23, a film feeding supporting roller 24 and a film storage support frame 25;

[0045] Both ends of the film storage roller 21 are respectively connected to the top of the film storage support frame 25 through sliding bearing seats, so that the film storage roller 21 can rotate relative to the film storage support frame 25, and the film storage roller 21 can move relative to the film storage support frame 25 in the vertical direction.

[0046] The film feeding driving roller 23 and the film feeding supporting roller 24 are respectively arranged on the opposite sides at the bottom of the film storage support frame 25; so that the film storage roller 21 is located above the gravity direction of the film feeding driving roller 23 and the film feeding supporting roller 24. During the operation of the equipment, as the plastic film 211 on the film storage roller 21 is consumed, under the action of its own mass and gravity, the film storage roller 21 can slide downward, so that the surface of the plastic film 211 at the bottom of the film storage roller 21 can always be in contact with the tops of the film feeding driving roller 23 and the film feeding supporting roller 24.

[0047] The film feeding driving part 22 is a servo motor. The film feeding driving part 22 has an output shaft, and the output shaft of the film feeding driving part 22 is connected to the film feeding driving roller 23 through a synchronous pulley transmission assembly; through the power provided by the film feeding driving part 22, the film feeding driving roller 23 is driven to rotate to send the plastic film 211 into the film opening device 30.

[0048] The film opening partition rod 31 of this embodiment is a slender cylindrical rod, and the number of the film opening partition rods 31 is 2;

[0049] The film opening device 30 further includes a first limiting component and a second limiting component. The first limiting component and the second limiting component are respectively arranged on opposite sides of the film opening partition rod 31, and are used to limit the film opening partition rod 31 between the first limiting component and the second limiting component. The first limiting component is arranged below the second limiting component in the direction of gravity; the plastic film 211 sent by the film storage device 20 passes through the first limiting component and the second limiting component in sequence from bottom to top. The film opening partition rod 31 is wrapped between the first limiting component and the second limiting component by the plastic film 211, and always approaches the lower second limiting component under the action of gravity, effectively preventing deviation.

[0050] Specifically, the first limiting component includes a first limiting fixed roller 32 and a first limiting movable roller 33. The first limiting fixed roller 32 and the first limiting movable roller 33 are arranged in parallel. A first limiting gap is formed between the first limiting fixed roller 32 and the first limiting movable roller 33. The first limiting gap allows the plastic film 211 to pass through. The maximum width of the first limiting gap is smaller than the diameter of the film opening partition rod 31 to prevent the film opening partition rod 31 from slipping out of the first limiting gap; the second limiting component includes a second limiting fixed roller 34 and a second limiting movable roller 35. The second limiting fixed roller 34 and the second limiting movable roller 35 are arranged in parallel. A second limiting gap is formed between the second limiting fixed roller 34 and the second limiting movable roller 35. The second limiting gap allows the plastic film 211 to pass through.

In this way, the film opening partition rod 31 is controlled between the first limiting component and the second limiting component.

[0051] A number of tension guiding rollers 50 are arranged between the film storage device 20 and the film opening device 30 in this embodiment, and a number of tension guiding rollers 50 are arranged between the film opening device 30 and the film guiding device 40; by winding the plastic film 211 around the circumferences of the respective tension guiding rollers 50 in sequence, the running direction of the plastic film 211 is guided, and at the same time, the wrap angle of the plastic film 211 on the tension guiding rollers 50 is increased. In this way, the tension of the plastic film 211 is adjusted to ensure that the plastic film 211 will not be damaged or distorted during the transmission process, maintaining the stability and cleanliness of the plastic film 211. At the same time, the plastic film 211 can also have a certain film storage function through the winding of many rollers, ensuring the continuous and stable supply of the plastic film 211 during the operation of the equipment.

[0052] The film pressing assembly 43 of this embodiment includes a rotating rod 431 and a pressing rod 432; both ends of the rotating rod 431 are rotatably connected to the mounting frame 10, the pressing rod 432 is fixed to one side of the rotating rod 431 through a connecting piece, and a pressing wheel 433 is arranged on the pressing rod 432, and a plurality of the pressing wheels 433 are evenly distributed along the axial direction of the pressing rod 432; by rotating the rotating rod 431, the pressing wheels 433 on the pressing rod 432 are driven to approach or move away from the conveying guide roller 42. The pressing wheel 433 can provide pressure for the plastic film 211 under its own gravity to press it on the surface of the conveying guide roller 42.

[0053] A rocker 434 is arranged on the rotating rod 431, and the rotating rod 431 is driven to rotate through the rocker 434; by swinging the rocker 434 to make the rotating rod 431 rotate counterclockwise, the pressing wheel 433 can be driven to move away from the conveying guide roller 42, creating a passage between the pressing wheel 433 and the conveying guide roller 42 for the loading of the plastic film 211; by swinging the rocker 434 to make the rotating rod 431 rotate clockwise, the pressing wheel 433 presses the plastic film 211 against the conveying guide roller 42; by applying pressure through a plurality of pressing wheels 433 arranged at intervals on the pressing rod 432, the layered plastic film 211 can be prevented from being squeezed and adhered together again.

[0054] Further, an elastic member 435 is arranged at the end of the rocker 434. The elastic member 435 can be a tension spring. One end of the elastic member 435 is connected to the end of the rocker 434, and the other end of the elastic member 435 is fixed to the mounting frame 10; by providing an elastic force through the tension spring, the pressing wheel 433 is stably pressed against the surface of the conveying guide roller 42.

[0055] The film guiding plate 44 of this embodiment includes two relatively arranged film guiding units. The film guiding unit includes a connecting rod 441. Both ends of the connecting rod 441 are respectively fixed to the mounting frame 10, and a plurality of elastic plates 442 are arranged at intervals on one side of the connecting rod 441; a film guiding channel that gradually narrows from wide to narrow is formed between the opposite elastic plates 442 on the two film guiding units. The wide end is arranged close to the film outlet direction of the conveying guide roller 42. After the plastic film 211 is sent out by the conveying guide roller 42, it enters the film guiding channel from the wide end. Through the guiding and automatic adjustment by a plurality of elastic plates 442 arranged at intervals on both sides, the plastic film 211 is kept flat, ensuring that it accurately enters the preset working area of the bagging machine.

[0056] The film feeding component of the automatic plastic bagging machine for formulated cut tobacco in this embodiment can effectively supply the plastic film 211. Even when using large rolls or multi-layer composite films, it can accurately unwind and layer the plastic film 211 and stably feed it into the working area of the bagging machine. This is particularly important for complex packaging requirements, can ensure the success rate of subsequent bag opening processes, avoid misalignment or pulling between the layers of the plastic film 211, improve the operating stability and production efficiency of the bagging machine, avoid bag breakage or excessive consumption caused by poor plastic film 211 feeding, thereby improving the control and management of production costs, improving production efficiency and packaging quality, and bringing greater flexibility and reliability to the production process.
