Technical Field

[0001] The invention relates to a paper bag machine, in particular to a pointed bottom bag making machine. Background Art

[0002] Pointed bottom bags are mainly used as food bags, mainly as packaging bags for instant foods such as toast or French fries. The existing bag making machines for making pointed bottom bags are arranged in the order of bag making with a paper tube unwinding component, an edge gluing component, a paper bag folding component, a traction component, a bag cutting component, a bag pressing and conveying component, a bag bottom gluing and forming component and a paper bag collecting component. The bag bottom gluing and forming component includes a drum transmission mechanism and a gluing mechanism. The drum in the drum transmission mechanism is provided with a plurality of bottom sealing grooves for the pointed bottom bag to be inserted. The pointed bottom bag is inserted into the drum through the bag pressing and conveying component, and then the gluing mechanism above the drum is used to glue and seal the bottom. The drum in the bag bottom gluing and forming component rotates to glue and seal the pointed bottom bag and then transport it to the paper bag collecting component. The gluing mechanism includes a glue holding component for storing glue and a glue coating roller for applying glue to the bottom of the pointed bottom bag in the drum. However, the existing pointed bottom bag making and manufacturing components also have the following defects:

[0003] The existing drum wheel is made by integral casting. Such a drum wheel needs to have multiple bottom sealing grooves, so the manufacturing cost is high and the entire drum wheel needs to be replaced when damaged. At the same time, there is still room for improvement in the bottom sealing process of the existing drum wheel.

[0004] The existing glue holding assembly needs to put glue into the glue holding box and then convey the glue to the glue coating roller through the bottom glue roller and then glue the pointed bottom bag. However, the glue flow of this glue holding assembly cannot be controlled and the glue holding box needs to be cleaned frequently, which is very troublesome. Summary of the invention

[0005] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0006] Provided is a pointed bottom bag making machine, wherein a glue containing device of the bag making machine can conveniently control the glue flow rate and is simple to clean; a drum wheel of the bag making machine is assembled, has low cost, and parts can be replaced individually during maintenance, which is more convenient for maintenance; and a bag clamping mechanism is arranged in the drum wheel so that the pointed bottom bag can be automatically clamped or released when the drum wheel rotates, thereby ensuring stability of the pointed bottom bag during the bottom sealing process.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pointed bottom bag making machine, comprising a frame, on which a paper roll unwinding component, an edge gluing component, a paper bag folding component, a traction component, a bag cutting component, a bag pressing and conveying component, a bag bottom gluing forming component and a paper bag collecting component are arranged in sequence according to the bag making order, the bag bottom gluing forming component comprises a drum wheel transmission mechanism and a gluing mechanism, the drum wheel transmission mechanism comprises a drum wheel and a driving component for driving the drum wheel to rotate, the gluing mechanism comprises a glue holding component for storing glue and a A glue coating roller is used to apply glue to the bottom of the pointed bottom bag in the drum wheel, and its characteristics are as follows: the drum wheel includes at least three drum wheel supporting plates and drum wheel side plates arranged on both sides of the drum wheel supporting plates and detachably connected to the drum wheel supporting plates, the drum wheel supporting plates are assembled into a drum wheel with the drum wheel side plates on both sides through connecting parts, a bottom sealing groove is provided between two adjacent drum wheel supporting plates, a glue-applying surface lower than the drum surface of the drum wheel is provided on the side of the bottom sealing groove corresponding to the rotation direction of the drum wheel, and a bag clamping mechanism for clamping or opening the pointed bottom bag entering the bottom sealing groove is provided at one end of the drum wheel corresponding to the bottom sealing groove.

[0008] By adopting the above technical scheme, the drum wheel that was originally integrally formed in the bag bottom gluing molding component is changed to be composed of multiple drum wheel supporting plates and two drum wheel side plates, so that the two ends of the drum wheel supporting plates can be fixedly connected to the drum wheel side plates by screws, thereby reducing the manufacturing difficulty and cost of the drum wheel. Since the bottom sealing groove on the drum wheel is used to glue the bottom of the pointed bottom bag during use, the glue will inevitably block the bottom sealing groove after a long time of use, so that the drum wheel loses the gluing and bottom sealing function. After the drum wheel supporting plate and the drum wheel side plates are assembled, when cleaning the glue, the drum wheel supporting plate that needs to be replaced or cleaned can be removed separately so that the drum wheel can continue to be used. By arranging a bag clamping mechanism in the bottom sealing groove, the drum wheel During rotation, the bag clamping mechanism can open and close in an orderly manner to help the pointed bottom bag to be transmitted and sealed, and ensure the stability of the pointed bottom bag during the sealing process. A gluing surface lower than the drum surface is set on the side of the bottom sealing groove corresponding to the rotation direction of the drum wheel. Since the gluing surface is lower than the surface of the drum wheel, the gluing mechanism will slightly fold the bottom of the pointed bottom bag with the bottom sealing groove as the folding line and send it into the bottom sealing groove, so that this part of the folded pointed bottom bag is located between the bag clamping mechanism and the bottom sealing groove, and the extended end is in contact with the gluing surface, which is convenient for gluing the bottom of the pointed bottom bag in the bottom sealing groove. At the same time, the rotation of the drum wheel cooperates with the bag clamping mechanism to swing in the bottom sealing groove to clamp the bottom plate of the pointed bottom bag in the bottom sealing groove to seal the bottom.

[0009] The above-mentioned pointed bottom bag making machine can be further configured as follows: the glue holding assembly includes a bottom glue frame, a glue holding plate and a bottom glue roller, the bottom glue frame is provided with a fixed support plate, the fixed support plate presses the glue holding plate onto the surface of the fixed support plate through a pressing device so that the glue holding plate can move on the surface of the fixed support plate, glue baffles are provided at both ends of the glue holding plate, and an arc-shaped contact surface for the bottom glue roller to rotate and apply glue is provided at one end of the glue baffle corresponding to the bottom glue roller, and an adjustment device for adjusting the distance between the arc-shaped contact surface and the bottom glue roller is provided between the fixed support plate and the glue holding plate.

[0010] The above technical scheme is adopted, by arranging a pressing device to fix the glue holding plate on the fixed support plate, that is, to ensure that the glue holding plate does not separate from the fixed support plate during operation, and the glue holding plate can be moved horizontally on the fixed support plate through the pressing device, and by arranging a glue baffle plate, the glue is fixed in the glue baffle plate, which is convenient for gluing and cleaning, and by arranging an arc contact surface, the bottom glue roller can stick to the glue from the glue baffle plate when rolling, so that the glue is transferred to the pointed bottom bag, and by arranging an adjusting device between the fixed support plate and the glue holding plate, the glue holding plate can adjust the distance between the arc contact surface and the bottom glue roller through the adjusting device, so as to control the glue flow rate and meet the different specifications of pointed bottom bags. The requirements for different dosages of glue when gluing the bottom, because the glue holding plate and the fixed support plate can be disassembled and separated by the pressing mechanism, it is also convenient for subsequent cleaning of glue, and at the same time, an automatic glue injection mechanism can be provided above the glue holding plate to cooperate with the glue holding assembly for gluing, so that cleaning after gluing is more convenient.

[0011] The above-mentioned pointed bottom bag making machine can be further configured as follows: the bag clamping mechanism includes a bag clamping shaft passed through the side plate of the drum wheel, and the bag clamping shaft is provided with a bag clamping blade that extends into the bottom sealing groove and cooperates with the glue upper surface to clamp or open the pointed bottom bag. One end of the bag clamping shaft extends out of the side plate of the drum wheel to form a driving end, and the driving end drives the bag clamping shaft to rotate, thereby driving the bag clamping blade to swing back and forth in the bottom sealing groove.

[0012] By adopting the above technical scheme, the drum transmission mechanism includes a drum and a driving assembly, and the driving assembly includes a main shaft driving the drum to rotate and a cam driving the driving end of the bag clamping shaft to rotate. The cam is fixed, and a small swing arm mounted on the driving end rotates together with the drum. The small swing arm swings the bag clamping shaft back and forth with the convex and concave movement of the cam, thereby controlling the bag clamping blade to cooperate with the gluing surface to complete the closing and opening action. This arrangement is ingenious and the driving end can adopt different driving methods to realize the back and forth rotation of the bag clamping shaft, thereby ensuring the stability of the pointed bottom bag during the bottom sealing process.

[0013] The above-mentioned pointed bottom bag making machine can be further configured as follows: the adjusting device includes movable baffles arranged at both ends of the glue holding plate, the fixed support plate is provided with an adjusting bolt at one end corresponding to the movable baffle, and a spring fixing seat at the other end, a spring is provided between the spring fixing seat and the movable baffle, one end of the movable baffle is abutted against the adjusting bolt, and the other end is abutted against the spring, and the glue holding plate adjusts the distance between the arc contact surface and the bottom glue roller through the adjusting bolt.

[0014] By adopting the above technical solution, by setting movable baffles at both ends of the glue containing plate and setting adjusting bolts and springs on the fixed support plate, when it is necessary to adjust the glue flow, it is only necessary to turn the adjusting bolt to move the movable baffle down and compress the spring to retract, thereby reducing the distance between the arc contact surface and the bottom glue roller, thereby achieving the purpose of reducing the glue flow.

[0015] The above-mentioned pointed bottom bag making machine can be further configured as follows: the pressing device includes a fixing seat fixed on one end of the fixed support plate corresponding to the glue baffle plate and a spring sheet detachably connected to the fixing seat, one end of the spring sheet is connected to the fixing seat, and the other end is against the glue baffle plate, and the glue containing plate is pressed against the surface of the fixed support plate through the glue baffle plate.

[0016] By adopting the above technical solution, a fixing seat is set on the fixed support plate, and a spring sheet is connected to the fixing seat by screws, so that the spring sheet is pressed onto the rubber baffle plate, thereby pressing the rubber plate onto the surface of the fixed support plate. At the same time, due to the use of the spring sheet, when disassembling the rubber plate, there is no need to frequently disassemble the spring sheet, and the loading and unloading can be completed by the elastic force of the spring sheet.

[0017] The above-mentioned pointed bottom bag making machine can be further configured as follows: a movable groove adapted to the spring sheet is opened at one end of the glue baffle plate corresponding to the spring sheet, and the glue containing plate can be adjusted forward and backward along the spring sheet through the movable groove.

[0018] By adopting the above technical scheme, a movable groove is opened on the glue baffle plate for the spring sheet to move forward and backward, so that when the glue plate adjusts the glue flow through the adjustment device, the glue plate can be guided by the spring sheet without shifting left and right, so that the gap between the glue plate and the bottom glue roller remains level, making the gluing more uniform.

[0019] The above-mentioned pointed bottom bag making machine can be further configured as follows: the bottom glue frame plate is provided with a leak-proof disk, the leak-proof disk is arranged at the bottom of the glue containing plate, one end of the leak-proof disk extends to the bottom of the bottom glue roller, and the length of the extended end is longer than the gap between the arc contact surface and the bottom glue roller.

[0020] By adopting the above technical solution, when the bottom glue roller rotates to apply glue, a small part of the glue is easy to drip. By arranging a leak-proof tray at the bottom of the glue containing plate, one end of the leak-proof tray extends to the bottom of the bottom glue roller, and the extended part is longer than the glue part of the glue containing plate corresponding to the bottom glue roller, so that the dripping glue can be collected, making the glue cleaning more convenient, and part of the glue can be recovered for continued use.

[0021] The above-mentioned pointed bottom bag making machine can be further configured as follows: bearings for rotating the bag clamping shaft are provided at both ends of the drum side plates corresponding to the bag clamping shaft.

[0022] By adopting the above technical solution, bearings are arranged at both ends of the bag clamping shaft so that the bag clamping shaft does not directly contact the drum side plate when rotating, thereby reducing friction, improving transmission effect and extending service life.

[0023] The above-mentioned pointed bottom bag making machine can be further configured as follows: a sealing cover is provided at one end of the drum side plate corresponding to the bearing to prevent the bearing from falling out.

[0024] With the above technical solution, since the bearing is arranged on the drum side plate, it is easy to fall out during the rotation process. A cover is arranged at one end of the drum side plate corresponding to the bearing to prevent the bearing from falling out of the drum side plate.

[0025] The above-mentioned pointed bottom bag making machine can be further configured as follows: at least two drum support blocks are provided between the drum side plates.

[0026] By adopting the above technical solution, in order to ensure the overall strength of the drum structure, a drum support is provided between the drum side plates at both ends so that the drum side plates support each other through the drum support.

[0027] The beneficial effects of the present invention are as follows: 1. A plurality of drum support plates and drum side plates are assembled into a drum, thereby reducing the manufacturing cost of the drum. At the same time, when the drum is damaged, parts can be replaced individually without replacing the entire drum, which is more convenient for repair and maintenance. A bag clamping mechanism is provided so that the pointed bottom bag can be automatically clamped or released when the drum rotates, thereby ensuring the stability of the pointed bottom bag during the bottom sealing process.

[0028] 2. The glue plate is fixed to the surface of the fixed support plate by a spring sheet, so that the glue plate can be loaded, unloaded and cleaned more conveniently. An adjustment device is set on the glue plate and the fixed support plate to adjust the distance between the arc contact surface and the bottom glue roller, thereby controlling the glue flow. A leak-proof plate is set to prevent glue from dripping.
