Description

Technical Field

[0001] The invention relates to the field of bag making machines, and in particular to a high-efficiency sealing and cutting device for bag making machines. Background Art

[0002] Bags are indispensable items in people's daily lives. People use bags to store and hold things for the convenience of carrying or collecting. With the development of the petrochemical industry, people have gradually developed a variety of plastic bags, which are not only light and thin, but also have certain strength and toughness, thus greatly increasing the convenience of people's use. At the same time, with the development of the express delivery industry, people's frequency of using express bags has also increased.

[0003] The bag making machine is a machine for making various plastic packaging bags or other material packaging bags. The sealing and cutting device is an important component used to seal and cut the continuous roll of bags into independent packaging bags. However, in actual use, the sealing and cutting device has the following defects: 1. The existing Chinese patent application number 2024220425427 discloses a cutter scraper mechanism for a bag making machine, including a sealing and cutting device with a cutter, a scraper mechanism is provided on one side of the cutter, and the scraper mechanism includes a scraper frame, a scraper block arranged on the scraper frame, and a linear transmission mechanism for driving the scraper block to slide relative to the scraper frame. The linear transmission mechanism is used to drive the scraper block to slide back and forth along the outer surface of the cutter. When in use, the scraper steering cylinder drives the driving gear to rotate eccentrically, thereby driving the driven gear to rotate. The driven gear in turn drives the scraper block to enter or leave the bottom of the cutter to realize the steering of the scraper block. At the same time, there is a scraper lifting cylinder that can drive the scraper The block is axially lifted and lowered close to or away from the cutter, thereby realizing the axial lifting and lowering of the scraper block and realizing the multi-directional movement control of the scraper block to meet complex cleaning needs. After this arrangement, the material block steering assembly and the material block lifting assembly do not interfere with each other and can work together to conveniently realize the steering and lifting of the scraper block; and the existing cutter scraper mechanism drives a scraper block to slide on the cutter surface through a linear transmission mechanism to remove residues on the cutter and prevent bag quality problems caused by adhesion. However, with the increase in bag specifications and the increase in the length of the cutter, the sliding scraping stroke of the scraper block becomes longer and longer, which will undoubtedly greatly reduce the production speed of the bag making machine and affect the overall efficiency.

[0004] 2. After cutting materials many times, the blade of the existing cutter will inevitably have a certain degree of wear. In order to increase the service life of the cutter, workers often need to manually apply maintenance oil to the blade of the cutter. However, this method is inefficient, affects production efficiency, has certain risks, causes injuries to workers, and also has the problem of uneven application.

[0005] 3. The existing Chinese patent application number CN201210054551.7 discloses a bag making machine, comprising a frame (10), a bag feeding device (20), a sealing and cutting device (30) and a bag collecting device (40), wherein the frame (10) is provided with a main transmission shaft (102), a secondary transmission shaft (109) and a swing shaft (112); the frame (10) is provided with a sealing and cutting device (30); the sealing and cutting device (30) is flipped and movably connected, and an operator can quickly and conveniently clean the sealing knife; the rotation of the main transmission shaft (102) can drive the sealing and cutting knife to move vertically in the axial direction, the bag pressing plate to move vertically in the axial direction, and the secondary eccentric wheel to rotate, and cooperate with the ejector rod (496) and the cylinder (497) on the side plate (41) of the bag collecting device (40) to make the bag collecting device (40) move vertically in the axial direction. The bag device (40) can swing slightly when making bags, so that the bags are misaligned, so that the sealing lines of the two bags after sealing and cutting will not stick to each other. In the above technical solution, when the bags are collected, the bag collecting needles are driven by the telescopic cylinder to pass through the surface of the plastic bags, and the plastic bags are strung together one by one. This causes the plastic bags to be poked with holes by the bag collecting needles, affecting the use of the bags. At the same time, the bag making machine needs to drive the entire bag collecting device to swing left and right to misalign the product heat sealing lines left and right to avoid the heat sealing lines between the two bags sticking to each other. However, this method has low structural processing efficiency, and because the heat sealing lines have residual temperature for a short time, even if the heat sealing lines are misaligned, a large number of bags are stacked on the bag collecting mechanism, resulting in some bags still sticking to other positions of adjacent bags. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a high-efficiency sealing and cutting device for a bag making machine in view of the deficiencies of the above-mentioned prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-efficiency sealing and cutting device for a bag making machine, comprising a frame, on which a traction and feeding bag mechanism, a sealing and cutting mechanism equipped with a cutter and a bag collecting mechanism are arranged, the traction and feeding bag mechanism is used to pull the bag body to the bottom of the cutting knife of the sealing and cutting mechanism for sealing and cutting, a bag-separating and anti-sticking mechanism is arranged between the sealing and cutting mechanism and the bag collecting mechanism for separating the ends of the bag body with heat-sealing lines after being sealed and cut by the sealing and cutting mechanism one by one, the bag collecting mechanism is used to stack the bag bodies sealed and cut by the sealing and cutting mechanism one by one on the bag collecting mechanism, and the bag bodies on the bag collecting mechanism have heat-sealing lines. One side of the bag separating and anti-sticking mechanism faces one end of the bag separating and anti-sticking mechanism, and a scraper mechanism is provided on one side of the sealing and cutting mechanism, and the scraper mechanism includes a plurality of scraper blocks arranged on one side of the cutter and a scraper sliding assembly driving the scraper blocks to slide along the surface of the cutter, and the bag separating and anti-sticking mechanism includes a bag separating roller rotatably arranged on a frame and a bag separating driving assembly driving the bag separating roller to rotate, and at least one baffle is provided on the outer peripheral surface of the bag separating roller, and the baffle divides the outer periphery of the bag separating roller into a plurality of bag separation areas, and with the drive of the bag separating driving assembly, separates the ends of the bag body with heat sealing lines after being sealed and cut by the sealing and cutting mechanism one by one.

[0008] By adopting the above technical scheme, the scraper block can be made of copper, steel, cloth and other materials to abut against the surface of the cutter, and then the scraper sliding assembly can drive the scraper block to slide along the surface of the cutter, so as to effectively remove the residue on the cutter, prevent the bag quality problems caused by adhesion, and realize efficient cutter scraping. The bag dividing drive assembly can be a separate drive source or can be set as the same drive source as the sealing and cutting mechanism, wherein the roller surface is divided into multiple bag separation areas by the baffles arranged on the outer peripheral surface of the bag dividing roller, and the sealing and cutting mechanism seals and cuts the connected bags one by one into independent bags, and stacks them at the front end of the sealing and cutting mechanism, and the bag dividing drive assembly drives the rotation of the bag dividing roller, and with the frequency of the sealing and cutting mechanism, the ends of the bag body with heat-sealed lines after sealing and cutting are separated one by one by the baffles. Due to the setting of the baffles, the heat-sealed lines with residual temperature will be separated from each other by the baffles first. After cooling, as the bag-splitting roller continues to rotate, the bag-collecting mechanism stacks the sealed and cut bags one by one on the bag-collecting mechanism, so that the bags can be stably collected together through the bag-collecting mechanism for subsequent unified packaging, and the side of the bag with the heat-sealing line can be stably directed toward one end of the bag-splitting roller, which is convenient for the baffle plate of the bag-splitting roller to separate the bags. At the same time, compared with the prior art, the bag-collecting needle is removed to avoid damage to the bag. Due to the short-term isolation of the baffle plate and the vortex caused by the rotation of the baffle plate on the bag-splitting roller, the heat-sealing line can be cooled in the fastest time to avoid adhesion. Compared with the prior art, this structure does not need to swing the bag-collecting mechanism to dislocate the bags, which simplifies the structure and reduces costs, and does not affect the bag processing efficiency, achieving high-speed bag separation and anti-sticking effect, and replacing manual scraping with a scraping mechanism to improve safety and scraping speed to achieve efficient bag sealing and cutting.

[0009] The above-mentioned efficient sealing and cutting device for a bag making machine can be further configured as follows: the bag dividing drive assembly includes a bag dividing deceleration component, and the bag dividing deceleration component is used to decelerate the driving force of the bag dividing drive assembly and drive the bag dividing roller to rotate, and make the speed ratio between the sealing and cutting mechanism and the bag dividing roller n, and n>1, and the number of baffles on the bag dividing roller is n.

[0010] By adopting the above technical scheme, the bag separating deceleration component is set to a gear reducer, a cycloidal reducer or other structures, and its input end can be a separate driving source or can be set to the same driving source as the sealing and cutting mechanism, wherein the bag separating deceleration component decelerates the driving force of the bag separating drive assembly and drives the bag separating roller to rotate, so that the speed ratio n>1, n is an integer, that is, when the sealing and cutting mechanism is n, the bag separating roller completes one circle, and the speed ratio n is preferably set to 9. At this time, the number of baffles is also 9, and the baffles are equidistantly arranged on the outer peripheral surface of the bag separating roller and divide it into 9 bag separation areas. Such a design ensures that the ends of the bag bodies after sealing and cutting can be effectively separated one by one, prevents adhesion between the bag bodies, improves the accuracy and reliability of bag separating, and does not require additional deceleration of the sealing and cutting mechanism to cooperate with the bag separating roller to separate bags, thereby achieving high-speed bag separating and anti-sticking effect.

[0011] The above-mentioned high-efficiency sealing and cutting device of a bag making machine can be further configured as follows: a sealing and cutting drive motor is provided on the frame, the sealing and cutting mechanism and the bag dividing drive assembly share the same sealing and cutting drive motor, the sealing and cutting drive motor drives the sealing and cutting mechanism to cut the bag body, and drives the bag dividing drive assembly to drive the bag dividing roller to rotate after deceleration through the bag dividing deceleration component to separate the ends of the bag body one by one, the sealing and cutting mechanism also includes a cutter drive assembly for driving the cutter to rise and fall axially, one end of the frame corresponding to the cutter is provided with a rotating motor spindle arranged on the frame, the sealing and cutting drive motor drives the motor spindle to rotate, and the motor spindle drives the cutter axially to rise and fall through the cutter transmission assembly linked to the cutter drive assembly, the bag dividing drive assembly also includes an active transmission sprocket arranged at one end of the motor spindle, a deceleration input sprocket arranged at the input end of the bag dividing deceleration component, and a transmission chain wound around the deceleration input sprocket and the active transmission sprocket, the output end of the bag dividing deceleration component is connected to the bag dividing roller, and the transmission chain transmits the power of the motor spindle to the bag dividing roller after deceleration through the bag dividing deceleration component.

[0012] By adopting the above technical scheme, a common sealing and cutting drive motor is used to drive the sealing and cutting mechanism to cut the bag body and the bag dividing drive component at the same time, and the bag dividing roller is driven to rotate after being decelerated by the bag dividing deceleration component to realize the separation of the ends of the bag body, thus ensuring the synchronization rate between the sealing and cutting mechanism and the bag dividing drive component, and ensuring that the machine body after debugging can stably put the end of the bag body into the corresponding bag separation area, so as to realize stable cooperation with the sealing and cutting mechanism, and the sealing and cutting drive motor drives the pulley linked to the motor main shaft through the belt to rotate, so that when the motor main shaft rotates, it can drive the cutter axially to reciprocate and lift to seal and cut the bag body through the cutter transmission component linked to the cutter drive component, and at the same time, the motor main shaft inputs power to the deceleration input sprocket of the bag dividing deceleration component through the active transmission sprocket and the transmission chain, and then drives the bag dividing roller to rotate after being decelerated by the bag dividing deceleration component, so as to realize stable and proportional synchronous operation of the sealing and cutting mechanism and the bag dividing drive component, and realize stable and highly synchronous cooperation.

[0013] The above-mentioned high-efficiency sealing and cutting device for a bag making machine can be further configured as follows: the cutter drive assembly includes a hot knife mounting plate loaded with a cutter, and a hot knife lifting shaft arranged at both ends of the hot knife mounting plate, one end of the hot knife lifting shaft is connected to the hot knife mounting plate, and the cutter transmission assembly includes an eccentric bearing eccentrically mounted on one end of a motor main shaft, the inner ring of the eccentric bearing is eccentrically connected to the motor main shaft, and the outer ring is provided with a hot knife hinge seat hinged to the hot knife lifting shaft, and the eccentric bearing drives the hot knife lifting shaft to rise and fall along the axial direction of the frame as the motor main shaft rotates, thereby driving the cutter to seal and cut the bags one by one.

[0014] By adopting the above technical solution, the inner ring of the eccentric bearing in the cutter transmission assembly is eccentrically connected to the motor main shaft, and the outer ring is hinged to the hot knife lifting shaft through the hot knife hinge seat. In this way, when the motor main shaft continues to rotate, the eccentric bearing of the cam structure will pull the hot knife lifting shaft to rise and fall along the axis of the frame, thereby driving the cutter to seal and cut the bags one by one, realizing a stable sealing and cutting process.

[0015] The above-mentioned high-efficiency sealing and cutting device of the bag making machine can be further configured as follows: a bag shifting mechanism is provided above the bag separating and anti-sticking mechanism corresponding to the frame, the bag shifting mechanism includes an upper bag shifting sprocket and a lower bag shifting sprocket axially arranged on both sides of the frame, a bag shifting chain wound around the upper bag shifting sprocket and the lower bag shifting sprocket, and a bag shifting driving component that drives the shifting chain to rotate, at least one bag shifting rod is correspondingly connected between the chain units of the bag shifting chain, the bag shifting driving component drives the bag shifting rod to rotate around the upper bag shifting sprocket and the lower bag shifting sprocket, and then shifts the bag bodies passing through the bag shifting mechanism and sends them into the bag separation area one by one, the bag shifting driving component includes a driven sprocket arranged on one of the lower bag shifting sprockets, the transmission chain is wound around the driven sprocket, and the bag shifting mechanism is driven by the transmission chain Synchronously linked with the sealing and cutting mechanism, the bag collecting mechanism includes an upper pressing plate, a lower pressing plate and a pressing drive assembly which are relatively arranged on the frame and drive the upper pressing plate axially close to or away from the pressing bottom plate; a collecting channel for bag stacking is formed between the upper pressing plate and the lower pressing plate; the pressing drive assembly includes pressing rods arranged at both ends of the upper pressing plate and a pressing swing arm shaft which is rotatably arranged on the frame; the motor main shaft is connected with the pressing swing arm shaft through a cam transmission assembly and drives the pressing swing arm shaft to rotate back and forth; pressing rod swing arms are provided between the two ends of the pressing rod and the pressing rod; one end of the pressing rod swing arm is hinged to the pressing rod, and the other end is fixedly connected to the pressing swing arm shaft; the pressing drive assembly is synchronously linked with the sealing and cutting mechanism through the pressing swing arm shaft.

[0016] By adopting the above technical scheme, the bag-moving driving assembly can be a separate driving source or can share a driving source with the sealing and cutting mechanism and / or the bag-splitting driving mechanism. Since the bags after being sealed and cut by the sealing and cutting mechanism are still partially connected together, the bag-moving mechanism drives the bag-moving rod to rotate around the upper bag-moving sprocket and the lower bag-moving sprocket through the bag-moving driving assembly, and after the bags passing through the bag-moving mechanism are moved apart into independent bag bodies, most of the bag bodies will fall onto the bag collecting mechanism for stacking, and the ends of the bags with heat-sealed lines will be moved apart by the bag-moving rod and then sent one by one to the corresponding bag separation areas below, thereby improving the bag separation efficiency and bag separation stability, assisting the bags to enter the bag separation areas, and reducing the adhesion between the bags. The bag-moving driving assembly includes a driven sprocket, and the transmission chain of the bag-moving mechanism is synchronously linked with the sealing and cutting mechanism to ensure the coordination of bag-moving and sealing and cutting, thereby improving the coordination of the bag-making process. The tonality and efficiency can ensure the stable synchronization among sealing, cutting, bag shifting and bag separation, and improve the coordination and efficiency of the bag making process. The bag collecting mechanism drives the upper pressing plate axially close to or away from the pressing bottom plate through the pressing drive assembly to form a collecting channel for bag stacking. The cam transmission assembly includes an eccentric bearing eccentrically mounted on the motor main shaft and a pressing swing arm fixedly mounted on the pressing swing arm shaft. The pressing swing arm is hinged to the outer ring of the eccentric bearing, and then drives the pressing swing arm shaft to rotate back and forth with the rotation of the motor main shaft. The rotation of the pressing swing arm also links the pressing rod swing arm to swing, and then drives the upper pressing plate axially to rise and fall back and forth. The cam transmission assembly is synchronously linked with the sealing and cutting mechanism to ensure the orderly stacking of the bags, ensure the stable and synchronous cooperation among sealing, cutting, bag gathering, bag shifting and bag separation, and improve the coordination and efficiency of the bag making process.

[0017] The above-mentioned efficient sealing and cutting device for a bag making machine can be further configured as follows: the bag separating roller includes a bag separating roller body and a plurality of paging sleeves sleeved on the bag separating roller body, the baffles are equidistantly distributed on the paging sleeves, and the baffles between adjacent paging sleeves are on the same horizontal plane.

[0018] By adopting the above technical scheme, the bag separating roller is composed of a bag separating roller body and a plurality of paging sleeves mounted on the bag separating roller body. The partition sheets are evenly distributed on the paging sleeves to ensure that the separation effect of each bag separation area is consistent. By setting the bag separating roller body and the paging sleeve separately, the paging sleeve can be easily processed to reduce the manufacturing cost, and the number of partition sheets on the paging sleeve can be conveniently adjusted to adapt to different bag body processing, and it is convenient for subsequent individual replacement and maintenance.

[0019] The above-mentioned high-efficiency sealing and cutting device of a bag making machine can be further configured as follows: the scraper mechanism also includes a scraper frame, a plurality of scraper assemblies loaded with the scraper blocks arranged on the scraper frame, and a scraper steering assembly that drives the scraper blocks to rotate synchronously so that the scraper blocks and the cutter are abutted against or separated. The scraper steering assembly includes a swing arm, a synchronous rocker rod and a rotation drive source that are arranged on the scraper frame corresponding to each group of scraper assemblies. One end of the swing arm is hinged to the scraper frame, and the other end is connected to the scraper block. The synchronous rocker rods are all connected to the swing arms, one of which is connected to the output end of the rotation drive source. The rotation drive source drives the swing arm to link the synchronous rocker rod so that the scraper blocks all rotate synchronously.

[0020] By adopting the above technical scheme, multiple scraper blocks are arranged on one side of the cutter, and the stroke of the original scraper block is segmented by multiple scraper blocks, and then the scraper sliding component and the scraper steering component of the scraper mechanism drive the multiple scraper blocks to slide and rotate synchronously, thereby improving the scraping efficiency, adapting to the cleaning needs of the long cutter, increasing the production speed of the bag making machine, shortening the original scraping time, and improving the efficiency. The rotation driving source is preferably a cylinder, and the scraper components are connected to one end of the swing arm, and the other end of the swing arm is hinged to the scraper frame. The swing arms are linked to each other through a synchronous rocker rod, so that only one cylinder is needed to drive one swing arm to swing, so as to realize the synchronous rotation of the scraper blocks, make the scraping action more coordinated, and improve the uniformity and efficiency of the scraping.

[0021] The above-mentioned efficient sealing and cutting device for a bag making machine can be further configured as follows: the scraper assembly includes a steering mounting plate mounted on a scraper frame, an active swing block and a driven gear shaft rotatably arranged on the steering mounting plate, one end of the driven gear shaft is provided with a driven gear meshing with the active swing block, and the other end is connected to the scraper block after passing through the steering mounting plate, the active swing block is provided with a connecting rod connected to the swing arm, the swing arm drives the active swing block to rotate and also rotates the scraper block, the connecting rod is eccentrically connected to the active swing block, and the number of teeth of the active swing block is greater than that of the driven gear shaft. The driven gear is connected with the scraper block and the driven gear shaft through a material block swing seat, and a scraper pre-tightening assembly is provided between the steering mounting plate and the scraper block, and the scraper pre-tightening assembly includes a pre-tightening spring sleeved on the outside of the driven gear shaft, a pre-tightening bracket arranged on the steering mounting plate, and an upper pre-tightening snap ring arranged on the outer circumference of the driven gear shaft, one end of the pre-tightening bracket is connected to the steering mounting plate, and the other end extends to the outer circumference of the driven gear shaft, one end of the pre-tightening spring is against the pre-tightening bracket, and the other end is against the upper pre-tightening snap ring, and prompts the scraper block to form a preload force to lift one end of the steering mounting plate.

[0022] The above technical scheme is adopted, the scraper assembly includes a steering mounting plate, an active swing block and a driven gear shaft, the active swing block is connected to the swing arm, and the active swing block is driven to rotate by the swing arm, thereby linking the scraper block to rotate, and through the design of the steering mounting plate and the active swing block, the scraper block and the swing arm are remotely linked to achieve flexible steering of the scraper block, so that the scraper mechanism can adapt to the scraping needs of different positions, and the eccentric connection of the connecting rod and the gear ratio design of the driven gear and the active swing block are improved, so that the swing efficiency and scraping force of the scraper block are improved, thus ensuring that the steering drive source only needs to rotate a small angle to drive the scraper block to rotate a large angle, thereby avoiding interference with the normal operation of the cutter. The setting of the material block swing seat also increases the swing diameter of the scraper block, which is conveniently and stably set at both ends of the cutter blade to improve the scraper efficiency. The design of the parts realizes the constant pre-tightening force of the scraper block on the cutter, so that the scraper block always has an upward pulling force, which ensures that it will automatically move down for buffering when entering the cutter edge, and pull up when below the cutter edge, thereby increasing the friction with the cutter and improving the scraper effect. After the scraper block is worn, it can automatically compensate for the worn area to avoid ineffective scraping, thereby improving the stability and consistency of the scraping effect. A lower pre-tightening clamp is provided on the movable sleeve on the outer peripheral surface of the driven gear shaft, and the pre-tightening spring is against the pre-tightening bracket through the lower pre-tightening clamp, and the upper pre-tightening clamp is detachably connected to the driven gear shaft. The design of the lower pre-tightening clamp avoids contact between the pre-tightening spring and the pre-tightening bracket, avoids the problem of spring loosening and bending, and improves stability. The upper pre-tightening clamp is detachably connected to the driven gear shaft, which is convenient for adjusting the preload force of the adjustment spring to adapt to different scraping environments.

[0023] The above-mentioned high-efficiency sealing and cutting device of a bag making machine can be further configured as follows: the scraper sliding assembly includes a scraper base, a scraper driving source arranged on the scraper base, and a linear guide rail arranged between the scraper base and the scraper frame, the linear guide rail is arranged parallel to the cutter, the scraper steering assembly is fixedly mounted on the scraper frame, the output end of the scraper driving source is connected to the scraper frame, and drives the scraper assembly to move back and forth along the linear guide rail, the scraper base is provided with at least one travel limiter in the sliding direction of the scraper frame, and the scraper frame is provided with a travel limit plate for limiting the position against the travel limiter.

[0024] By adopting the above technical scheme, the scraper driving source is preferably a scraper cylinder, which drives the scraper frame and the scraper steering assembly to slide together, thereby realizing the rapid reciprocating movement of the scraper assembly along the cutter, improving the scraping speed and production efficiency, and realizing precise control of the scraper assembly stroke through the design of the stroke limiter and the stroke limit plate, thereby ensuring the accuracy and safety of the scraping action and avoiding invalid scraping and scraper block slipping out.

[0025] The above-mentioned high-efficiency sealing and cutting device for a bag making machine can be further configured as follows: the scraper mechanism also includes an oiling mechanism, which includes an oil supply valve arranged on the scraper base, a diverter connected to the oil supply valve, and an oil dripping interface arranged on one side of each scraper component. The oil dripping interface is respectively connected to the diverter, and the lubricating oil at the oil supply valve is sent to the corresponding scraper block through the oil dripping interface. One side of the scraper component is provided with an oil receiving head which is respectively connected to the diverter, and the oil receiving head is connected to the oil dripping interface by an infusion tube. The oil receiving head is installed on the scraper frame, and the scraper base is provided with a solenoid valve for controlling the supply of the oiling mechanism.

[0026] By adopting the above technical scheme and designing the oiling mechanism, workers only need to inject lubricating oil at the oil supply valve, and then deliver the lubricating oil to the oil dripping interface of each scraper assembly through the diverter, so that the oil dripping interface drips the lubricating oil onto the corresponding scraper block. In this way, when the scraper block is scraping on the surface of the cutter, the cutter will be automatically oiled and maintained at the same time, thereby improving the service life of the cutter and the maintenance efficiency of the scraper mechanism. The oil supply of the oiling mechanism is controlled by controlling the solenoid valve, so as to achieve accurate oil supply to the scraper block, so that workers do not need to frequently add oil, and the oil supply amount and oil supply time are accurately controlled, thereby improving the stability and efficiency of the oiling mechanism.

[0027] The present invention has the following beneficial effects: 1. Through the integrated sealing, cutting, bag separation, bag shifting and bag collecting mechanisms, continuous automatic production is achieved, which significantly reduces costs and improves the synchronization and production efficiency of the bag making machine.

[0028] 2. The bag separation and anti-sticking mechanism effectively separates the sealed and cut bags one by one through its innovative rotating bag separation roller and baffle plate design to prevent the heat sealing lines from sticking together, thereby improving production efficiency, reducing material waste, and ensuring the independence and quality of the bags. The mechanism has strong adaptability, is easy to operate, reduces maintenance costs, and at the same time improves the stability and environmental performance of bag handling, meeting the modern packaging industry's demand for efficient, stable and environmentally friendly production equipment. The baffle plate design on the bag separation roller effectively separates the newly sealed and cut bags, reduces the adhesion between the heat sealing lines, and solves the problem of bag adhesion in traditional methods.

[0029] 3. The automatic scraping and oiling maintenance functions of the scraping mechanism reduce the need for manual maintenance, reduce maintenance costs and labor intensity. The automatic scraping and oiling mechanism reduces manual operation and reduces the risk of workers being injured during operation.

[0030] 4. By sharing the drive motor and transmission chain, the mechanical structure of the equipment is simplified, the complexity and failure rate of the equipment are reduced. By precisely controlling the synchronous operation of each mechanism, energy waste is reduced, energy saving and consumption reduction are achieved. The synchronous linkage of each mechanism reduces the impact and collision in the production process and improves the stability and reliability of the equipment.

[0031] 5. The number of baffles on the bag-separating roller can be adjusted according to the specifications of the bag body. It has good adaptability and can handle bags of different sizes and specifications, which improves the adaptability of the equipment.

[0032] 6. The bag collecting mechanism achieves orderly stacking through its double-plate stacking design. It is equipped with axial drive and synchronous linkage mechanism to adapt to the stacking requirements of bags of different thicknesses. The automatic adjustment function can adapt to the increasing bag height, avoid bag damage, and improve collection efficiency. It has strong structural stability, simple operation, strong adaptability, reduces manual intervention, and ensures high efficiency and bag integrity in the bag making process.

[0050] like Figure 1-Figure 16 As shown, a high-efficiency sealing and cutting device for a bag making machine comprises a frame 1, on which a traction and feeding bag mechanism 2, a sealing and cutting mechanism 3 equipped with a cutter 31, and a bag collecting mechanism 5 are provided. The traction and feeding bag mechanism 2 is used to pull the bag body C to the bottom of the cutter 31 of the sealing and cutting mechanism 3 for sealing and cutting. A bag-dividing and anti-sticking mechanism 6 is provided between the sealing and cutting mechanism 3 and the bag-dividing and anti-sticking mechanism 6 for separating the ends of the bag body C with a heat-sealing line after being sealed and cut by the sealing and cutting mechanism 3 one by one. The bag-dividing and anti-sticking mechanism 6 is used to stack the bag bodies C sealed and cut by the sealing and cutting mechanism 3 one by one on the bag-dividing and anti-sticking mechanism 6, and the bag bodies C on the bag-dividing and anti-sticking mechanism 6 on the bag-dividing and anti-sticking mechanism 6 are arranged. A scraping mechanism 4 is provided on one side of the sealing and cutting mechanism 3. The scraping mechanism 4 comprises a plurality of scraping blocks 41 arranged on one side of the cutter 31 and a scraping sliding assembly for driving the scraping blocks 41 to slide along the surface of the cutter 31. A bag-dividing mechanism 7 is provided on the frame 1 corresponding to the bag-dividing and anti-sticking mechanism 6 for separating the sealed and cut bag bodies C one by one and sending them to the bag-dividing and anti-sticking mechanism 6.

In order to ensure the efficiency and stability of bag separation, the number of baffles on the paging sleeve 611 is also set to 9, and the 9 bag separation areas 613 at the bag separation roller separation are synchronized with the power of the sealing and cutting mechanism 3 and the bag separation and anti-sticking mechanism 6, and then the speed ratio is converted to 9:1 through the bag separation deceleration component 62, and the end parts of the bag body c with the heat sealing line after sealing and cutting by the sealing and cutting mechanism 3 are sent one by one to the rotating bag separation area 613 to be separated, and the heat is reduced while having a short separation time to avoid adhesion.

[0053] like Figure 1-Figure 12As shown, a sealing and cutting drive motor 30 is provided on the frame 1, and the sealing and cutting mechanism 3 and the bag-dividing drive assembly share a sealing and cutting drive motor 30. The sealing and cutting drive motor 30 drives the sealing and cutting mechanism 3 to cut the bag body c, and drives the bag-dividing drive assembly to decelerate through the bag-dividing deceleration component 62, and then drives the bag-dividing roller 61 to rotate to separate the ends of the bag body c one by one. The sealing and cutting mechanism 3 also includes a cutter drive assembly for driving the cutter 31 to axially rise and fall. One end of the frame 1 corresponding to the cutter 31 is provided with a motor spindle 32 rotatably arranged on the frame 1.

Two staggered bag-moving rods 74 are correspondingly connected between the chain units of the corresponding bag-moving chains 73 on both sides, and the bag-moving driving assembly drives the bag-moving rods 74 to rotate around the upper bag-moving sprocket 71 and the lower bag-moving sprocket 72, thereby moving the bags a passing through the bag-moving mechanism apart and sending them one by one into the bag separation area 613. The bag-moving driving assembly includes a driven sprocket 721 arranged on the lower bag-moving sprocket 72 on one side, and the transmission chain 64 is wound around the driven sprocket 721.

By rotating the adjustment handle 712, the initial positions of the two bag-moving rods 74 can be conveniently adjusted so that the space between the bag-moving rods 74 can just allow the bag body c to pass from the sealing and cutting mechanism 4 to enter the bag collecting mechanism 5. In this way, when the bag-moving mechanism 7 is working subsequently, the bag body a at the sealing and cutting mechanism 3 can be continuously and stably moved through one of the bag-moving rods 74, and the other bag-moving rod 74 can guide the broken bag body c into the bag separation area 613 below, thereby assisting in completing the bag-moving.

The bag collecting mechanism 5 includes an upper pressing plate 51 and a bottom pressing plate 52 which are relatively arranged on the frame 1, and a pressing driving component which drives the upper pressing plate 51 to axially approach or move away from the bottom pressing plate 52. A collecting channel 53 for stacking bags c is formed between the upper pressing plate 51 and the bottom pressing plate 52. The pressing driving component includes pressing rods 54 which are arranged at both ends of the upper pressing plate 51 and a pressing swing arm shaft 55 which is rotatably arranged on the frame 1. The motor main shaft 32 is connected to the pressing swing arm shaft 55 through a cam transmission assembly 56, and drives the pressing swing arm shaft 55 to rotate back and forth. There are pressing rod swing arms on both sides of the pressing swing arm shaft 55 and the pressing rod 54.

[0056] like Fig.11As shown, the bag collecting mechanism 5 also includes a bag stacking assembly arranged at the material pressing bottom plate 52, which can be gradually moved downward relative to the frame 1 to expand the material collecting channel 53. The bag stacking assembly includes bag stacking screw sleeves 58 arranged on both sides of the material pressing bottom plate 52, bag stacking screws 581 inserted in the bag stacking screw sleeves 58, and a bag stacking motor 59 for driving the bag stacking screws 581 to rotate. One end of the bag stacking screw 581 is connected to the bag stacking motor 59 through a synchronous belt 591, and the other end is threadedly connected to the bag stacking screw sleeve 58. The bag stacking motor 59 drives the bag stacking screw 59 to rotate, so that the material pressing bottom plate 52 gradually moves away from the material pressing upper plate 51. When the sealed and cut bags c in the sealing and cutting mechanism 3 enter the material collecting channel 53 one by one, the material pressing driving assembly will drive the material pressing upper plate 51 to press the bags c onto the material pressing bottom plate 52 one by one, so that the bags are stacked one by one. When the bags c are stacked one by one, the material collecting channel 5 3 will gradually become thicker and the bag stacking motor 59 can drive the bag stacking screw 581 to rotate through the synchronous belt 591, and the bag stacking screw 581 will drive the pressing base plate 52 to rise and fall axially when rotating, thereby controlling the pressing base plate 52 to gradually move away from the pressing upper plate 51, and gradually expand the collecting channel 53 during the stacking process of the bag bodies c, so that the bag bodies c can be stably stacked in the collecting channel 53 for subsequent overall discharge. Compared with the prior art, the bag collecting needle is removed to avoid damage to the bag body, and the speed and width of the bag stacking assembly can be controlled according to the bag bodies of different thicknesses. In addition, due to the gradual descent of the pressing base plate 52, the height of the subsequently stacked bag bodies c will not change, so that no matter how many bag bodies c are stacked, the heat sealing lines of the bag bodies c can fall into the bag separation area 613 of the bag separation and anti-sticking mechanism 6 for bag separation, thereby avoiding the occurrence of bag sticking problems to the greatest extent.

[0057] It should be noted that the sprocket chain, synchronous belt, synchronous wheel and pulley belt in the device can be simply interchanged with each other, and such simple interchange should be considered within the protection scope of the present invention.
