Description

Technical Field

[0001] This utility model relates to the technical field of paper feeding equipment for bag making machines, specifically a paper feeding mechanism for a bag making machine guide belt. Background Technology

[0002] In the packaging and printing industries, bag-making machines are key pieces of equipment that turn rolls of paper packaging materials into various bags. The paper feeding mechanism is the starting station of the bag-making machine, and its function is to accurately transport the rolls of paper to subsequent processing units.

[0003] However, many equipment's subsequent processing units require the paper to be in a vertical position to facilitate subsequent processing. This requires the paper feeding mechanism to complete the orientation change of the paper from horizontal to nearly vertical during the conveying process.

[0004] However, existing technologies still have shortcomings in use: in the curved area where the paper changes from horizontal to vertical transport, traditional paper feeding mechanisms lack effective support for the paper, especially for paper with a large basis weight or brittle material. Under the action of its own weight and traction force, the curved part will generate large internal stress. This stress concentration can easily cause the paper to tear or crease at the turning point, which seriously affects the strength and appearance of the finished bag, resulting in material waste and production interruption. Moreover, due to the lack of guidance and restraint, the paper in a free state is very likely to rub against other equipment next to the paper feeding mechanism when turning. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a paper feeding mechanism for a bag making machine. In the curved area where the paper changes from horizontal to vertical, the guide belt can not only effectively support the paper and prevent it from tearing and creases at the turning point, but also guide and constrain the paper to prevent it from rubbing against other equipment next to the paper feeding mechanism. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding mechanism for a bag making machine, comprising a paper feeding platform, a template beam vertically arranged on the paper feeding platform, an mounting plate arranged at the end of the paper feeding platform away from the template beam, an upper conveyor roller and a lower conveyor roller respectively arranged on the mounting plate via a rotating shaft one and a rotating shaft two, a motor arranged on the mounting plate, and the output shaft of the motor being fixedly connected to the rotating shaft one, a pressing groove being formed on the template beam, a guide belt pressing assembly being arranged on the pressing groove, the guide belt pressing assembly fixing one end of the guide belt in the pressing groove, a fixing groove being formed on the upper surface of the paper feeding platform away from the template beam, and the fixing groove being close to the edge of the paper feeding platform, a guide belt fixing assembly being arranged in the fixing groove, the guide belt fixing assembly fixing the other end of the guide belt in the fixing groove, the guide belt being soft.The guide belt is made of flexible PVC roll material. Different lengths of PVC roll material can be cut according to the actual needs. During use, the guide belt needs to be fixed first, ensuring one end is between the guide belt clamping plate and the clamping groove. Because paper widths vary, the guide belt needs to be set at different heights on the template beam to effectively support the paper. The guide belt clamping plate has limit strips of different heights, which can hold the guide belt between two guide belts, keeping it at different heights and preventing displacement. Holding the handle and turning it rotates the handle, which drives the turntable to rotate. The turntable then drives the clamping screw to rotate, which in turn drives... The movable plate moves, causing the guide column to move, which in turn moves the guide belt clamping plate until it is fully inserted into the clamping groove. The clamping plate then presses and fixes one end of the guide belt, placing the other end between the guide belt fixing plate and the fixing groove. Turning the handwheel rotates the fixing screw, which in turn moves the movable plate downwards. The movable plate then moves the sliding column downwards, which in turn moves the guide belt fixing plate downwards until it is fully inserted into the fixing groove. This clamps and fixes the other end of the guide belt, thus securing the guide belt and placing the paper to be conveyed between the upper and lower conveyor rollers. The paper is then manually moved from horizontal to vertical... The paper gradually bends to a vertical position, fixing the vertically positioned paper onto the next processing equipment. At this point, the paper is pressed against the template beam. The motor is then turned on, and its output shaft drives the upper conveyor roller to rotate counter-clockwise via a rotating shaft. With the cooperation of the upper and lower conveyor rollers, the paper is conveyed forward. In actual use, the guide belt effectively supports the paper, preventing tearing or creases at bends, thus protecting the strength and appearance of the finished bags. It also prevents material waste and production interruptions caused by paper tearing or creases. Furthermore, it guides and restrains the paper, preventing it from rubbing against other equipment next to the paper feeding mechanism. Because the paper... The paper surface is covered with paper scraps. To clean the paper scraps, the connecting pipe is connected to an external vacuum cleaner. The motor's output shaft can also drive the driven gear to rotate clockwise via the active gear on the rotating shaft. The driven gear drives the cleaning roller to rotate clockwise via the cleaning shaft. The soft cleaning bristles on the cleaning roller sweep the paper scraps from the paper surface to the suction nozzle of the suction strip. The paper scraps then enter the external vacuum cleaner through the suction strip and connecting pipe, thus completing the cleaning and collection of paper scraps. The motor can not only transport the paper, but also clean the paper scraps with the cleaning roller through the cooperation of the active and driven gears, enhancing the utilization of the motor and saving costs.

[0007] Furthermore, the guide belt pressing assembly is a movable plate movably disposed on the side of the template beam away from the pressing groove. A guide post is horizontally disposed on the side of the movable plate facing the template beam. The guide post passes through a guide hole opened in the pressing groove, and a guide belt pressing plate that cooperates with the pressing groove is disposed at the end of the guide post passing through the guide hole. A pressing screw is rotatably disposed on the side of the template beam facing the movable plate through a bearing. The pressing screw passes through the movable plate and is threadedly connected to the movable plate. The gap between the guide belt pressing plate and the pressing groove is less than the thickness of the guide belt.

[0008] Furthermore, the guide belt pressing plate has several limiting strips evenly spaced on one side facing the pressing groove. The gap between two adjacent limiting strips is equal to the width of the guide belt, and the thickness of the limiting strip is less than the thickness of the guide belt. The limiting strips can hold the guide belt in place, preventing displacement of the guide belt during long-term use.

[0009] Furthermore, the guide belt pressing plate has friction protrusions evenly spaced on one side facing the pressing groove, and the pressing groove has friction recesses evenly spaced inside, corresponding to the friction protrusions. When the guide belt pressing plate is fully inserted into the pressing groove, the friction protrusions press the guide belt into the friction recesses, thereby enhancing the tightness of the guide belt.

[0010] Furthermore, a turntable is provided at the outer end of the clamping screw. The turntable increases the rotation radius, making rotation easier.

[0011] Furthermore, a handle is provided at an off-center position on the turntable. Holding the handle and turning it allows the turntable to rotate more quickly.

[0012] Furthermore, the guide belt fixing assembly is a movable plate movably disposed below the paper feeding platform, and the movable plate corresponds to the fixing groove. A sliding column is vertically disposed on the movable plate, and the sliding column passes through a sliding hole opened in the fixing groove. A guide belt fixing plate is disposed at the end of the sliding column passing through the sliding hole. The guide belt fixing plate cooperates with the fixing groove, and the gap between the guide belt fixing plate and the fixing groove is less than the thickness of the guide belt. A fixing screw is rotatably disposed on the lower surface of the paper feeding platform through a bearing. The fixing screw passes through the movable plate, and the fixing screw is threadedly connected to the movable plate. A handwheel is disposed at the lower end of the fixing screw.

[0013] Furthermore, the mounting plate is equipped with a cleaning roller via a cleaning shaft, and the cleaning roller is evenly provided with soft cleaning bristles. The mounting plate is provided with a suction strip that cooperates with the cleaning roller, and the suction nozzle of the suction strip is close to the lower end of the soft cleaning bristles on the cleaning roller. One end of the suction strip is provided with a connecting pipe. The rotating shaft and the cleaning shaft are respectively provided with a driving gear and a driven gear, and the driving gear and the driven gear mesh with each other.

[0014] Based on the above technical solution, the beneficial effects achieved by the paper feeding mechanism of the bag making machine guide belt after practical application are as follows: 1. This utility model utilizes a guide belt, which changes from horizontal to vertical, to effectively support the paper and prevent quality problems such as tearing or creases at bends. This prevents the strength and appearance of the finished bag from being affected, avoids material waste and production interruption caused by paper tearing or creases, and can also guide and restrain the paper to prevent it from rubbing against other equipment next to the paper feeding mechanism.

[0015] 2. This utility model utilizes a limiting strip to hold the guide belt at different heights. The guide belt mainly supports the paper near the edge to provide effective support. Therefore, for paper of different widths, guide belts of different heights provide effective support for the paper.

[0016] 3. This utility model utilizes the cooperation between the active gear and the passive gear, enabling the motor to not only transport paper, but also to clean paper scraps with the cleaning roller through the cooperation of the active gear and the passive gear, thereby enhancing the utilization of the motor and saving costs.

Detailed Implementation

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This embodiment provides a technical solution: a paper feeding mechanism for a bag making machine, including a paper feeding platform 1, a template beam 2 vertically arranged on the paper feeding platform 1, an mounting plate 20 arranged at the end of the paper feeding platform 1 away from the template beam 2, an upper conveying roller 13 and a lower conveying roller 29 respectively arranged on the mounting plate 20 through a first rotating shaft 21 and a second rotating shaft 22, a motor 12 arranged on the mounting plate 20, and the output shaft of the motor 12 is fixedly connected to the first rotating shaft 21, a pressing groove 24 is opened on the template beam 2, a guide belt pressing assembly is arranged on the pressing groove 24, the guide belt pressing assembly fixes one end of the guide belt 8 in the pressing groove 24, a fixing groove 27 is opened on the upper surface of the paper feeding platform 1 away from the template beam 2, and the fixing groove 27 is close to the edge of the paper feeding platform 1, a guide belt fixing assembly is arranged in the fixing groove 27, the guide belt fixing assembly fixes the other end of the guide belt 8 in the fixing groove 27, and the guide belt 8 is soft.The guide belt 8 is made of soft PVC roll material. Different lengths of PVC roll material can be cut according to the actual needs. During use, the guide belt 8 needs to be fixed first, with one end positioned between the guide belt clamping plate 18 and the clamping groove 24. Since the width of the paper varies, the height of the guide belt 8 on the template beam 2 needs to be different for each width of paper to effectively support it. The guide belt clamping plate 18 is equipped with limit strips 32 of different heights, which can hold the guide belt 8 between two guide belts 8, ensuring that the guide belt 8 is at different heights and preventing displacement. Holding the handle 7 and turning it causes the turntable 6 to rotate, which in turn rotates the clamping screw 5, which in turn moves the movable plate 4. The movable plate 4 moves the guide column 3, which in turn moves the guide belt pressing plate 18 until it is fully inserted into the pressing groove 24. The guide belt pressing plate 18 then presses and fixes one end of the guide belt 8, placing the other end of the guide belt 8 between the guide belt fixing plate 9 and the fixing groove 27. Turning the handwheel 31 rotates the fixing screw 30, which in turn moves the movable plate 11 downwards. The movable plate 11 then moves the sliding column 10 downwards, which in turn moves the guide belt fixing plate 9 downwards until it is fully inserted into the fixing groove 27. The guide belt fixing plate 9 then presses and fixes the other end of the guide belt 8, thus fixing the guide belt 8 and placing the paper to be conveyed between the upper conveyor roller 13 and the lower conveyor roller 29. The paper is manually bent from horizontal to vertical, and then fixed in the vertical position on the equipment for the next process. At this time, the paper is close to the template beam 2. The motor 12 is turned on, and the output shaft of the motor 12 drives the upper conveyor roller 13 to rotate counterclockwise through the rotating shaft 21. With the cooperation of the upper conveyor roller 13 and the lower conveyor roller 29, the paper is conveyed forward. In actual use, the guide belt 8 can effectively support the paper, avoiding tearing or creases at the bends, preventing quality problems such as affecting the strength and appearance of the finished bag. It also prevents material waste and production interruption caused by paper tearing or creases. It can also guide and restrain the paper, preventing it from rubbing against other equipment next to the paper feeding mechanism. Because the paper has a coating on its surface during production... To clean paper scraps from the paper surface, the connecting pipe 17 is connected to an external vacuum cleaner. The output shaft of the motor 12 can also drive the driven gear 16 to rotate clockwise via the active gear 15 on the rotating shaft 21. The driven gear 16 drives the cleaning roller 14 to rotate clockwise via the cleaning shaft 23. The soft cleaning bristles on the cleaning roller 14 sweep the paper scraps from the paper surface to the suction nozzle of the suction strip 19. The paper scraps enter the external vacuum cleaner through the suction strip 19 and the connecting pipe 17, thus completing the cleaning and collection of paper scraps. The motor 12 can not only transport paper, but also enable the cleaning roller 14 to clean paper scraps through the cooperation of the active gear 15 and the driven gear 16, which enhances the utilization of the motor 12 and saves costs.

[0026] Furthermore, the guide belt clamping assembly is a movable plate 4 movably disposed on the side of the template beam 2 away from the clamping groove 24. A guide post 3 is horizontally disposed on the side of the movable plate 4 facing the template beam 2. The guide post 3 passes through the guide hole 26 opened in the clamping groove 24, and the end of the guide post 3 passing through the guide hole 26 is provided with a guide belt clamping plate 18 that cooperates with the clamping groove 24. A clamping screw 5 is rotatably disposed on the side of the template beam 2 facing the movable plate 4 through a bearing. The clamping screw 5 passes through the movable plate 4 and is threadedly connected to the movable plate 4. The gap between the guide belt clamping plate 18 and the clamping groove 24 is less than the thickness of the guide belt 8.

[0027] Furthermore, a plurality of limiting strips 32 are evenly and equidistantly arranged on the side of the guide belt pressing plate 18 facing the pressing groove 24. The gap between two adjacent limiting strips 32 is equal to the width of the guide belt 8, and the thickness of the limiting strip 32 is less than the thickness of the guide belt 8. The limiting strips 32 can hold the guide belt 8 in place, preventing the guide belt 8 from shifting during long-term use.

[0028] Furthermore, friction protrusions 33 are evenly and equidistantly arranged on the side of the guide belt pressing plate 18 facing the pressing groove 24, and friction recesses 25 corresponding to the friction protrusions 33 are evenly and equidistantly opened inside the pressing groove 24. When the guide belt pressing plate 18 is fully inserted into the pressing groove 24, the friction protrusions 33 press the guide belt 8 into the friction recesses 25, thereby enhancing the tightness of the guide belt 8.

[0029] Furthermore, a turntable 6 is provided at the outer end of the clamping screw 5. The turntable 6 increases the rotation radius, making rotation easier.

[0030] Furthermore, a handle 7 is located at an off-center position on turntable 6. By gripping and turning handle 7, turntable 6 can be rotated more quickly.

[0031] Furthermore, the guide belt fixing assembly is a movable plate 11 movably disposed below the paper feeding platform 1, and the movable plate 11 corresponds to the fixing groove 27. A sliding column 10 is vertically disposed on the movable plate 11, and the sliding column 10 passes through the sliding hole 28 opened in the fixing groove 27. A guide belt fixing plate 9 is disposed at the end of the sliding column 10 passing through the sliding hole 28. The guide belt fixing plate 9 cooperates with the fixing groove 27, and the gap between the guide belt fixing plate 9 and the fixing groove 27 is less than the thickness of the guide belt 8. A fixing screw 30 is rotatably disposed on the lower surface of the paper feeding platform 1 through a bearing. The fixing screw 30 passes through the movable plate 11, and the fixing screw 30 is threadedly connected to the movable plate 11. A handwheel 31 is disposed at the lower end of the fixing screw 30.

[0032] Furthermore, the mounting plate 20 is equipped with a cleaning roller 14 via the cleaning shaft 23. The cleaning roller 14 is evenly provided with soft cleaning bristles. The mounting plate 20 is equipped with a suction strip 19 that cooperates with the cleaning roller 14. The suction nozzle of the suction strip 19 is close to the lower end of the soft cleaning bristles on the cleaning roller 14. One end of the suction strip 19 is equipped with a connecting pipe 17. The rotating shaft 21 and the cleaning shaft 23 are respectively equipped with a drive gear 15 and a driven gear 16, and the drive gear 15 and the driven gear 16 mesh with each other.

[0033] The working principle of the paper feeding mechanism of the bag making machine provided by this utility model is as follows: During use, the guide belt 8 needs to be fixed first, with one end of the guide belt 8 positioned between the guide belt clamping plate 18 and the clamping groove 24. Since different paper widths exist, the guide belt 8 needs to be positioned at different heights on the template beam 2 to effectively support the paper. The guide belt clamping plate 18 is equipped with limit strips 32 of varying heights, which can hold the guide belt 8 between two guide belts 8, ensuring they are at different heights and preventing displacement. Holding the handle 7 and turning it rotates the handle, which in turn rotates the turntable 6. The turntable 6 then rotates the clamping screw 5, which in turn moves the movable plate 4. The movable plate 4 moves the guide column 3, which in turn moves the guide belt clamping plate 18 until... After the guide belt clamping plate 18 is fully inserted into the clamping groove 24, it clamps and fixes one end of the guide belt 8, so that the other end of the guide belt 8 is between the guide belt fixing plate 9 and the fixing groove 27. Turning the handwheel 31 drives the fixing screw 30 to rotate, which in turn moves the movable plate 11 downwards. The movable plate 11 then moves the sliding column 10 downwards, which in turn moves the guide belt fixing plate 9 downwards until the guide belt fixing plate 9 is fully inserted into the fixing groove 27. The guide belt fixing plate 9 then clamps and fixes the other end of the guide belt 8, thus completing the fixation of the guide belt 8. This places the paper to be conveyed between the upper conveyor roller 13 and the lower conveyor roller 29. The paper is then manually bent from horizontal to vertical. The paper is fixed on the equipment for the next process. At this time, the paper is close to the template beam 2. The motor 12 is turned on, and the output shaft of the motor 12 drives the upper conveyor roller 13 to rotate counterclockwise through the rotating shaft 21. With the cooperation of the upper conveyor roller 13 and the lower conveyor roller 29, the paper is conveyed forward. In actual use, the guide belt 8 can effectively support the paper, avoiding tearing or creases at the turning points, preventing quality problems such as affecting the strength and appearance of the finished bag. It will not cause material waste or production interruption due to paper tearing or creases. It can also guide and restrain the paper, preventing the paper from scratching other equipment next to the paper feeding mechanism. Since paper scraps are attached to the surface of the paper during production, the paper scraps on the surface of the paper need to be cleaned. The connecting pipe 17 is connected to an external vacuum cleaner. The output shaft of the motor 12 can also drive the driven gear 16 to rotate clockwise through the active gear 15 on the rotating shaft 21. The driven gear 16 drives the cleaning roller 14 to rotate clockwise through the cleaning shaft 23. The soft cleaning bristles on the cleaning roller 14 sweep the paper scraps on the paper surface to the suction nozzle of the suction strip 19. The paper scraps enter the external vacuum cleaner through the suction strip 19 and the connecting pipe 17, thus completing the cleaning and collection of paper scraps. The motor 12 can not only transport the paper, but also clean the paper scraps of the cleaning roller 14 through the cooperation of the active gear 15 and the driven gear 16. This enhances the utilization of the motor 12, eliminates the need for multiple motors, and saves costs.
