Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a dual-machine parallel line structure for packaging and bagging. Background Technology

[0002] A bag-making machine is a specialized piece of machinery used to produce various types of plastic bags. It uses processes such as heating, pressing, and cutting to turn plastic film into bags of various sizes. Bag-making machines are mainly used in the plastic packaging industry to produce shopping bags, garbage bags, food bags, and other plastic packaging bags.

[0003] Currently, bag-making equipment generally operates on a single line, unwinding film and producing packaging bags on a single line. This results in low efficiency in the production and processing of packaging bags. To achieve dual-line production, two unwinding mechanisms need to be installed, each matched to a different bag-making machine. This not only increases production and operating costs but also increases the space required for the equipment. Therefore, the structure needs to be improved. Utility Model Content

[0004] This utility model discloses a dual-line packaging and bagging structure. By incorporating a dual-line synchronous unwinding mechanism, two rolls of film can be respectively mounted on two unwinding rollers during operation. These rollers are then positioned by a cap and a second limiting plate. One end of each roll is introduced into the inlet of one of the two bag-making machines. At this point, a dual-head motor is activated. This motor, in conjunction with two second gears and two first gears, stably drives the unwinding shaft to rotate, thereby synchronously and stably driving the two unwinding rollers to rotate, allowing for simultaneous unwinding of the two film rolls. This enables simultaneous bag-making operations on two lines, significantly improving bag-making efficiency. Furthermore, since both unwinding rollers are driven by the same dual-head motor, stability and synchronization are high. Simultaneously, it effectively reduces production and operating costs and minimizes the overall footprint of the dual-line equipment. In summary, this invention solves the problems described in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a dual-machine parallel structure for packaging and bagging, including a processing table, the bottom of which is provided with multiple support legs, two bag-making machines fixedly installed on the top of the processing table, and an mounting frame fixedly installed on the top of the processing table, the mounting frame being in the shape of an inverted U-shape.

[0007] A dual-line synchronous unwinding mechanism includes a mounting base, bearings, an unwinding shaft, and a dual-head motor. The mounting base is fixedly installed on the top of the processing table. A through mounting groove is opened inside the mounting base, and two bearings are fixedly installed in the mounting groove. The unwinding shaft passes through the inside of the two bearings and is fixedly connected to the inner ring of the bearings. An unwinding roller is fixedly connected to each end of the unwinding shaft. A cap is screwed to the end of the unwinding roller away from the unwinding shaft. A first gear is fixedly fitted on the outside of the unwinding shaft. The dual-head motor is fixedly installed on the top of the mounting base. A second gear is fixedly connected to each of the two output ends of the dual-head motor. The second gear meshes with the first gear.

[0008] A cleaning mechanism is installed inside and on one side of the mounting frame.

[0009] Furthermore, the two unwinding rollers are symmetrically designed with the mounting base as the center of symmetry, and the positions of the two unwinding rollers are respectively matched with the inlet positions of the two bag-making machines.

[0010] Furthermore, a first limiting plate is provided at one end of the unwinding roller near the unwinding shaft, and a second limiting plate is fixedly connected to the side of the cover near the unwinding roller.

[0011] Furthermore, the cleaning mechanism includes a brush roller and a drive motor. There are two brush rollers, both of which are rotatably mounted inside the mounting frame. The two brush rollers are installed in an up-down configuration. The outer circumference of each brush roller is provided with a bristle section. One end of each brush roller is provided with a transmission gear, and the two transmission gears are meshed together. The drive motor is fixedly mounted on the outer side of the mounting frame through a mounting component, and the output end of the drive motor is connected to the shaft end of one of the brush rollers.

[0012] Furthermore, the adjacent bristle portions of the two bristle rollers are in contact with each other, and the bristle portions of the bristle rollers are made of microfiber bristle material.

[0013] Furthermore, a dust collection box and an exhaust fan are fixedly installed on the top of the mounting frame, and multiple exhaust fans are provided. The exhaust ends of the multiple exhaust fans are all connected to one side of the dust collection box. Multiple L-shaped ducts are connected to the other side of the dust collection box. The bottom end of the ducts is connected to a dust collection hood. The dust collection hood is located between the unwinding roller and the mounting frame. A filter plate is movably installed inside the dust collection box.

[0014] Furthermore, a door is hinged to one side of the dust collection box, and the door is sealed to the dust collection box when closed.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution features a dual-line synchronous unwinding mechanism, which allows for the simultaneous unwinding of two rolls of film during operation. This enables the simultaneous bag-making process with two bag-making machines, significantly improving bag-making efficiency. Furthermore, the dual-line synchronous unwinding mechanism is driven by the same dual-head motor, resulting in high stability and good synchronization. It also effectively reduces the production and operating costs of the equipment and minimizes the overall footprint of the dual-line equipment, making it highly practical.

[0017] 2. This technical solution incorporates a cleaning mechanism that effectively removes dust particles and film fragments from both the upper and lower surfaces of the film material before it enters the bag-making equipment's feed inlet.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-3 A dual-line packaging and bagging structure includes a processing table 1 with multiple support legs at its bottom. Two bag-making machines 2 are fixedly mounted on the top of the processing table 1, and a mounting frame 3 is fixedly mounted on the top of the processing table 1. The mounting frame 3 is in the shape of an inverted U. A dual-line synchronous unwinding mechanism 4 includes a mounting base 401, bearings 402, an unwinding shaft 403, and a dual-head motor 404. The mounting base 401 is fixedly mounted on the top of the processing table 1, and a through mounting groove 405 is formed inside the mounting base 401. Two bearings 402 are fixedly mounted in the mounting groove 405. The unwinding shaft 402... 03 passes through the interior of two bearings 402 and is fixedly connected to the inner ring of the bearings 402. An unwinding roller 406 is fixedly connected to each end of the unwinding shaft 403. A cover 407 is screwed onto the end of the unwinding roller 406 away from the unwinding shaft 403. A first gear 408 is fixedly fitted on the outside of the unwinding shaft 403. A dual-head motor 404 is fixedly installed on the top of the mounting base 401. A second gear 409 is fixedly connected to each of the two output ends of the dual-head motor 404. The second gear 409 meshes with the first gear 408. A cleaning mechanism 5 is installed inside the mounting frame 3 and on one side of the outside.

[0029] The two unwinding rollers 406 are symmetrically designed with the mounting base 401 as the center of symmetry, and the positions of the two unwinding rollers 406 are respectively matched with the inlet positions of the two bag making machines 2; a first limiting plate 410 is provided at one end of the unwinding roller 406 near the unwinding shaft 403, and a second limiting plate 411 is fixedly connected to the side of the cover 407 near the unwinding roller 406.

[0030] In the specific implementation process, during operation, two rolls of film can be respectively mounted on two unwinding rollers 406, and limited by the cap 407 and the second limiting plate 411. Then, one end of each roll of film is introduced into the feed inlet of the two bag making machines 2. At this time, the double-head motor 404 can be started. The double-head motor 404 can work with the two second gears 409 and the two first gears 408 to stably drive the unwinding shaft 403 to rotate, thereby synchronously and stably driving the two unwinding rollers 406 to rotate synchronously, so as to unwind the two rolls of film synchronously. In this way, the two bag making machines 2 can start bag making work synchronously, which greatly improves the efficiency of bag making processing.

[0031] Among them, the unwinding roller 406 is symmetrically designed with the mounting base 401 as the center of symmetry, and the positions of the two unwinding rollers 406 are matched with the inlet positions of the two bag making equipment 2 respectively. This is so that the unwinding roller 406 can be well matched with the two bag making equipment 2 for use, and ensure the product quality of the packaging bag making process.

[0032] The first limiting plate 410 and the second limiting plate 411 can effectively limit the membrane material, thereby preventing the membrane material from sliding, moving or even slipping off. Specific Implementation Example 2:

[0034] Reference Figure 1 , Figure 4 as well as Figure 5 In a preferred embodiment, the cleaning mechanism 5 includes a brush roller 501 and a drive motor 502. There are two brush rollers 501, both of which are rotatably mounted inside the mounting frame 3. The two brush rollers 501 are mounted in an up-down configuration. The outer circumference of the brush roller 501 is provided with a bristle portion. One end of each of the two brush rollers 501 is provided with a transmission gear 503. The two transmission gears 503 are meshed and connected. The drive motor 502 is fixedly mounted on the outer side of the mounting frame 3 through a mounting component, and the output end of the drive motor 502 is connected to the shaft end of one of the brush rollers 501.

[0035] Two brush rollers 501 have their adjacent brush bristles in contact with each other. The brush bristles of the brush rollers 501 are made of microfiber brush bristle material. A dust collection box 6 and an exhaust fan 7 are fixedly installed on the top of the mounting frame 3. There are multiple exhaust fans 7. The exhaust ends of the multiple exhaust fans 7 are all connected to one side of the dust collection box 6. Multiple L-shaped ducts 8 are connected to the other side of the dust collection box 6. The bottom end of the ducts 8 is connected to a dust collection hood 9. The dust collection hood 9 is located between the unwinding roller 406 and the mounting frame 3. A filter screen plate 10 is movably installed inside the dust collection box 6. A box door 11 is hinged to one side of the dust collection box 6. When the box door 11 is closed, it is sealed to the dust collection box 6.

[0036] In the specific implementation process, during operation, the film material can be introduced into the feed port of the bag making equipment 2 through the two brush rollers 501. This allows the two brush rollers 501 to rotate synchronously through the operation of the drive motor 502 and the two transmission gears 503 before the film material moves into the feed port of the bag making equipment 2. This effectively cleans the upper and lower surfaces of the film material between the two brush rollers 501, removing dust particles and film material fragments, thus preventing dust particles and film material fragments from entering the bag making equipment 2 with the film material and affecting the quality of the finished product.

[0037] The two brush rollers 501 have their adjacent brush bristles in contact with each other to ensure that both the upper and lower surfaces of the film can be cleaned effectively. The brush bristles of the brush rollers 501 are made of microfiber bristles because microfiber bristles have excellent cleaning ability, while being soft and not damaging to the film, making them suitable for cleaning high-quality packaging bag films.

[0038] When cleaning surface dust particles and membrane fragments from the membrane material, multiple exhaust fans 7 can be activated. These fans, in conjunction with the dust collection box 6 and multiple ducts 8, generate suction at multiple dust collection hoods 9. The impurities and membrane fragments generated and dispersed during cleaning are drawn into the dust collection box 6 for centralized collection. The impurities are then intercepted by the filter screen 10 and retained in the dust collection box 6, facilitating subsequent centralized cleaning and preventing them from being dispersed in large quantities and re-attached to the membrane material. This also avoids harming nearby workers and effectively improves the environmental friendliness and safety of the equipment.

[0039] The dust collection box 6 can be cleaned by opening the door 11. The door 11 is sealed to the dust collection box 6 when closed to ensure the overall airtightness of the dust collection box 6, so that the exhaust fan 7 can work with the dust collection box 6 and the duct 8 to generate sufficient suction at the dust collection hood 9.

[0040] Working principle: During operation, two rolls of film can be respectively mounted on two unwinding rollers 406 and limited by the cap 407 and the second limiting plate 411. Then, one end of each roll of film is introduced into the feed inlet of the two bag making machines 2. At this time, the double-head motor 404 can be started. The double-head motor 404 can work with the two second gears 409 and the two first gears 408 to stably drive the unwinding shaft 403 to rotate, thereby synchronously and stably driving the two unwinding rollers 406 to rotate synchronously, so as to unwind the two rolls of film synchronously. In this way, the two bag making machines 2 can start bag making work synchronously, which greatly improves the efficiency of bag making processing.

[0041] Furthermore, during operation, the film material can be introduced into the inlet of the bag making equipment 2 through the space between the two brush rollers 501. This allows the two brush rollers 501 to rotate synchronously via the drive motor 502 and the two transmission gears 503 before the film material moves into the inlet of the bag making equipment 2. This effectively cleans the upper and lower surfaces of the film material between the two brush rollers 501, removing dust particles and film material fragments. This effectively prevents dust particles and film material fragments from entering the bag making equipment 2 with the film material and affecting the quality of the finished product.

[0042] When cleaning surface dust particles and membrane fragments from the membrane material, multiple exhaust fans 7 can be activated. These fans, working in conjunction with the dust collection box 6 and multiple ducts 8, generate suction at multiple dust collection hoods 9. This suction draws the generated and dispersed impurities and membrane fragments into the dust collection box 6 for centralized collection. The impurities are then intercepted by the filter screen 10 and retained in the dust collection box 6, facilitating subsequent centralized cleaning and preventing them from being dispersed and re-attached to the membrane material. This also avoids harming nearby workers and effectively improves the environmental friendliness and safety of the equipment.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
