[0002] A bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. Patent application number: CN202322082509.2 discloses a bag making machine that is easy to collect, including a support frame, on which a bag making machine is installed; one side of the support frame is provided with a collecting mechanism that is easy to collect packaging bags. Among them, the collecting mechanism includes a mounting groove, a collecting groove and a roller. When making film bags, the prepared film bags will be transported to the collecting groove through a conveyor belt after slitting, but after the film bags enter the collecting groove, they will fall from the height to the bottom of the collecting groove, making the film bags entering the collecting groove very chaotic, which is not conducive to later collection.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a hot-cut lifting and collecting device used on a bag making machine.

[0005] The present invention can be implemented by the following technical solutions:

[0006] The present invention discloses a hot-cutting lifting and collecting device used in a bag-making machine, comprising a frame, a hot-cutting transmission shaft is arranged on the frame, and the hot-cutting transmission shaft is driven to rotate by a main motor, and hot-cutting cams are also arranged on both sides of the hot-cutting transmission shaft, and hot-cutting sliding bars slidably connected to the frame are arranged on both sides of the frame, and a knife holder is arranged between the two hot-cutting sliding bars, and a hot-cutting knife is fixed at the bottom of the knife holder, and the hot-cutting cam is connected to the hot-cutting sliding bars at corresponding positions through a hot-cutting pulling plate, and a knife seat roller is also arranged on the frame below the hot-cutting knife. Material pressing support plates are also symmetrically arranged on both sides of the hot-cutting transmission shaft, and material pressing slide bars slidably connected to the material pressing support plates are arranged on the material pressing support plates, a fixing plate is fixed between the material pressing slide bars, a material pressing top plate is arranged under the fixing plate, and a plurality of material pressing positioning rods are fixed on the material pressing top plate, and the material pressing positioning rods The cam is connected to the cam rocker arm on the hot cutting transmission shaft, and the cam rocker arm is connected to the cam rocker arm through a connecting plate, and the cam rocker arm is connected to the cam rocker arm through a connecting plate, and the cam rocker arm is connected to the cam rocker arm through a connecting plate, and the cam push plates are fixed on both sides of the cam push plate, and the cam push plates are connected to the cam slide rod at the corresponding position through a cam push rod.

[0007] Preferably, the frame is also provided with a swing transmission shaft, which is connected to the hot-cut transmission shaft through a synchronous belt, eccentric wheels are fixed on both sides of the swing transmission shaft, and swing push rods are fixed on the press support plate at positions corresponding to the eccentric wheels. Cylinders are also provided on both sides of the frame, and the piston rod ends of the cylinders are connected to the corresponding press support plates. A swing transmission shaft is arranged on the frame, and the swing transmission shaft rotates with the hot cutting transmission shaft. The piston rod on the cylinder is shortened to realize that the end of the pressing push rod on the pressing support plate is against the eccentric wheel and moves on the surface of the eccentric wheel. After the packaging bag is hot-cut, the pressing top plate presses the hot-cut packaging bag onto the pressing support plate. After the eccentric wheel rotates a certain angle, due to the structural characteristics of the eccentric wheel, the eccentric wheel pushes the pressing push rod to move a certain position, and the pressing support plate rotates a certain angle around the hot cutting transmission shaft, so that the pressing top plate and the pressing support plate can rotate a certain angle with the pressing support plate, and the hot-cut packaging bag moves a certain position with the pressing top plate and the pressing support plate, that is, the edge of the hot-cut position of the packaging bag can be moved to a certain position, and when the next packaging bag is hot-cut again, the hot-cut positions of two adjacent packaging bags can be avoided from overlapping, thereby avoiding adjacent packaging bags from sticking together.

[0008] Preferably, two chain drive shafts are arranged between the two pressing support plates, sprockets are fixed on both sides of the chain drive shafts, the sprockets at corresponding positions on the two chain drive shafts are connected by the cutting chain, and multiple cutting push rods are fixed between the two cutting chains, a main sprocket is fixed on one of the chain drive shafts, a slave sprocket is fixed on the hot cutting drive shaft, and the slave sprocket is connected to the main sprocket by a chain.

[0009] Preferably, a mounting plate is fixed between the two pressing support plates, the lifting motor is fixed on the mounting plate, a lifting transmission shaft is arranged below the mounting plate, a first bevel tooth is fixed to the output end of the lifting motor, a second bevel tooth meshing with the first bevel tooth is fixed on the lifting transmission shaft, third bevel teeth are fixed on the lifting transmission shaft at positions corresponding to the screw rod, the screw rod passes through the mounting plate and is rotatably connected to the mounting plate, and fourth bevel teeth meshing with the third bevel teeth at the corresponding position are fixed to the bottom of the screw rod.

[0010] Preferably, a plurality of air tubes are arranged on both sides of the hot cutter, and air holes are evenly arranged on the air tubes. After the packaging bag passes through the air tubes, air is ejected through the air holes on the air tubes to flatten the packaging bag at the position of the hot cutter, which is convenient for hot cutting by the hot cutter, and the packaging bag is hot cut after being flattened, ensuring that the hot cutting position of the packaging bag is flat.

[0011] Working principle: A receiving plate is set on the frame on one side below the pressing support plate. After the packaging bag passes under the hot cutting knife, it passes between the pressing top plate and the pressing support plate, and the end of the packaging bag slides onto the receiving plate. The packaging bag is tilted and leans between the receiving plate and the pressing support plate. The main motor drives the hot cutting transmission shaft to rotate. When the hot cutting transmission shaft rotates, the hot cutting cam at the end of the hot cutting transmission shaft pulls the hot cutting slide bar to move through the hot cutting pull plate. When the hot cutting slide bar descends, the hot cutting knife descends with the hot cutting slide bar. The hot cutting knife cooperates with the knife seat roller to heat-cut the edge of the packaging bag. After the packaging bag is hot-cut, the hot cutting knife rises and the hot cutting knife is heated. The cutter is separated from the packaging bag, and the hot cutting drive shaft drives the pressing drive shaft to rotate back and forth through the pressing cam and the connecting plate. When the pressing drive shaft rotates, the pressing push plate drives the pressing slide bar to move up and down through the pressing push rod. When the pressing slide bar descends, the pressing top plate fixes one end of the packaging bag on the pressing support plate, and the chain drive shaft rotates with the hot cutting active shaft. When the chain drive shaft rotates, the cutting chain rotates. Since multiple cutting push rods are fixed between the two cutting chains, the packaging bag is cut after passing through the two cutting chains. The cutting push rod rotates with the cutting chain and approaches the hot cutting The cutting push rod on one side of the knife rises to separate the packaging bag cut by heat from the packaging bag on the other side of the hot cutting knife. After the cut packaging bag is separated from the packaging bag on the other side of the hot cutting knife, the cutting push rod close to the side of the pressing support plate descends, and the cutting push rod close to the side of the pressing support plate bends the end of the cut packaging bag and covers it on the pressing support plate to collect the packaging bags. After the packaging bags are collected, the lifting motor drives the screw to rotate. When the screw rotates, the threaded tube descends in the direction of the screw, the lifting support plate descends, the pressing support plate descends, and after the hot cutting drive shaft rotates, the pressing top plate is separated from the pressing support plate, and the packaging One end of the bag descends with the pressing support plate, and the next packaging bag to be cut passes between the pressing top plate and the pressing support plate. The end of the packaging bag reaches the receiving plate position again, and the packaging bag is hot cut and collected again, and the cycle operation is carried out. This device can continuously cut and collect the packaging bags, and when the packaging bags are cut, the packaging bags are set at a larger inclination angle, and the end of the packaging bag leans against the pressing support plate. After the packaging bags are collected, the pressing support plate descends to a certain height to facilitate the end of the next packaging bag to slide onto the receiving plate, which can effectively avoid confusion of the packaging bags and facilitate the neat stacking and collection of the packaging bags.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This device can continuously cut and collect packaging bags. When the packaging bags are cut, the packaging bags are set at a larger tilt angle, and the end of the packaging bags leans against the pressing plate. After the packaging bags are collected, the pressing plate drops to a certain height to facilitate the end of the next packaging bag to slide onto the receiving plate, which can effectively avoid confusion of packaging bags and facilitate neat stacking and collection of packaging bags.

[0014] 2. After the packaging bag is cut, the end of the packaging bag is bent downward and leaned against the pressing plate through the action of the cutting push rod, that is, the packaging bag at the pressing plate position can be made the highest position, which can effectively prevent the cut packaging bag from affecting the movement of the next packaging bag.
