Description

Technical Field

[0001] This utility model relates to the technical field of paper bag rope handle bonding equipment, specifically a bag making machine rope handle forming and bonding machine. Background Technology

[0002] In the manufacturing process of paper bags, drawstring handles are usually added for easy carrying. In modern bag-making processes, the attachment of the drawstring handle is typically completed in two stages: First, the drawstring handle is initially positioned and pre-attached to the predetermined location on the paper using methods such as gluing or heat sealing; then, to ensure a strong, durable, and aesthetically pleasing connection between the drawstring handle and the paper, the pre-attached drawstring handle must be rolled and tightened. This tightening process is crucial to the overall quality and durability of the paper bag.

[0003] Currently, the mainstream fastening process uses a two-roller pressing mechanism. This mechanism typically consists of a smooth-surfaced pressure roller (glossy roller) and a pressure roller with a semi-circular groove on its surface (grooved roller). Paper with a pre-attached cord passes between these two rollers. The semi-circular groove on the grooved roller serves to precisely accommodate and position the cord during the pressing process, preventing it from rolling, shifting, or deforming during the final pressing. The glossy roller provides uniform support to the back of the paper. Together, they precisely concentrate strong pressure on the bonding area between the cord and the paper, expelling air and promoting adhesive penetration, thereby achieving a secure and permanent bond for the cord.

[0004] During the fastening and bonding stage, the matching degree between the grooved roller radius and the rope handle diameter is extremely important. If a grooved roller with an excessively large radius is used to press a thin rope handle, the pressing pressure cannot be effectively and concentrated on the rope handle, resulting in insufficient fastening force, weak bonding, and other defects. The rope handle is very likely to fall off during use. Conversely, if a grooved roller with an excessively small radius is used to press a thick rope handle, it will cause excessive compression to the rope handle, which may lead to deformation, damage, or even crushing of the paper, similarly affecting the product's strength and appearance.

[0005] However, existing technology still has shortcomings in use: the radius of the semi-circular groove of the groove roller on a machine is fixed. This design is based on the assumption of producing a single specification of product. However, in the actual market, paper bags have various specifications and uses, and the required rope handle diameters are also different. When the production task needs to switch from one diameter of rope handle to another, the operator must stop the machine and perform a cumbersome roller replacement process: disassemble the current fixed groove roller and install a new groove roller whose groove radius is precisely matched with the new rope handle diameter. This seriously affects the production efficiency and continuity of the equipment. Each replacement leads to a long downtime and cannot meet the flexible production needs of small batches and multiple varieties. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide a bag making machine rope handle forming and bonding machine. It can quickly switch the groove rollers of semi-circular grooves with different radii according to rope handles of different diameters. It is easy to operate, saves time, has little impact on the production efficiency and continuity of the equipment, and adapts to the flexible production needs of small batches and multiple varieties. It can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bag-making machine rope handle forming and bonding machine, comprising a rope handle bonding worktable, a support plate provided on the upper surface of one end of the rope handle bonding worktable, a paper guide roller rotatably mounted on the support plate via a paper guide rod, two corresponding fixing plates provided on the upper surface of the other end of the rope handle bonding worktable, a pressing rod rotatably mounted on the fixing plate via a bearing, a smooth roller mounted on the pressing rod, and an adjusting cylinder rotatably mounted on the fixing plate via a bearing, the adjusting cylinder being hollow inside, an adjusting rod slidably mounted inside the two adjusting cylinders, a plurality of grooved rollers evenly spaced at equal intervals on the adjusting rods, and a plurality of semi-circular grooves of different radii evenly opened at equal angles on the grooved rollers, the grooved rollers cooperating with the smooth rollers, a rope handle grooved roller adjusting assembly provided inside the adjusting cylinders, and the rope handle grooved roller adjusting assembly connected to the end of the adjusting rods, a driving assembly provided on the fixing plate, and the driving assembly being drivenly connected to the adjusting cylinders, and the adjusting cylinders being drivenly connected to the pressing rods. The paper with the pre-attached rope handle passes around the guide roller and is guided to the pressing area between the smooth roller and one of the grooved rollers. At this time, the geared motor starts, driving the transmission gear meshing with it through the drive gear, thereby rotating the adjusting cylinder. Since the two transmission gears are meshed, the pressing rod and the adjusting cylinder rotate synchronously in opposite directions. The grooved roller and the smooth roller in the pressing area rotate together, pressing the paper with the pre-attached rope handle passing between them. The rope handle is precisely embedded in the semi-circular groove of the corresponding radius on the grooved roller, and the tight bonding is completed under strong pressure. When it is necessary to produce paper bags with a different diameter rope handle, the operator does not need to disassemble any rollers, but only needs to rotate the adjusting screw to achieve rapid bonding. Switching is achieved by the operator rotating the adjusting screw. Since the adjusting screw is threadedly connected to the mounting bracket, rotation causes the adjusting screw to move axially. The inner end of the adjusting screw is connected to the circular groove at the end of the adjusting rod through a bearing. Therefore, the axial movement of the adjusting screw directly pushes or pulls the entire adjusting rod to slide within the adjusting cylinder. As the adjusting rod moves axially, the multiple grooved rollers installed at equal intervals on it also move. The operator moves the adjusting rod until the grooved roller with the required radius semi-circular groove is aligned with the pressing position of the smooth roller. Once the target grooved roller is in place, the switching is complete. The entire process is simple to operate, saves time, and has minimal impact on the production efficiency and continuity of the equipment, making it suitable for flexible production needs of small batches and multiple varieties.

[0008] Furthermore, the rope handle groove roller adjustment assembly is a guide block set on the adjustment rod. The adjustment cylinder has an adjustment guide groove that cooperates with the guide block. The end of the adjustment rod has a circular groove, and the inside of the circular groove is rotatably connected to the inner end of the adjustment screw through a bearing. The fixed plate is provided with a mounting bracket corresponding to the adjustment screw. The adjustment screw passes through the mounting bracket, and the adjustment screw is threadedly connected to the mounting bracket through a thread.

[0009] Furthermore, the drive component is a geared motor mounted on a fixed plate, and the geared motor is fixedly connected to the fixed plate via a connecting plate.

[0010] Furthermore, the output shaft end of the geared motor is provided with a drive gear, and both the pressing rod and the adjusting cylinder are provided with transmission gears, with the two transmission gears meshing with each other, and the drive gear meshing with one of the transmission gears.

[0011] Furthermore, a molding gasket is provided in the semi-circular groove. The molding gasket can be made of wear-resistant or elastic material, which can protect the surface of the rope handle from scratches and increase the clamping force during pressing, making the fit more secure.

[0012] Furthermore, the paper guide roller is provided with an anti-deviation film. The anti-deviation film can increase the friction between the paper and the pre-attached rope handle, effectively preventing the paper from deviating during the feeding process.

[0013] Furthermore, a turntable is provided at the outer end of the adjusting screw. The turntable increases the rotation radius, making rotation easier.

[0014] Furthermore, a rotating rod is provided at an eccentric position on the turntable. The rotating rod allows the turntable to rotate more quickly.

[0015] Based on the above technical solution, the beneficial effects achieved by this utility model bag making machine rope handle forming and bonding machine through practical application are as follows: This invention comprises an axial adjustment system consisting of an adjusting screw, a threaded pair of a mounting bracket, a bearing rotatably connected to the end of the adjusting rod, and a sliding engagement between a guide block on the adjusting rod and an adjusting guide groove on the adjusting cylinder. The operator only needs to rotate the adjusting screw to drive the entire adjusting rod to slide axially within the adjusting cylinder, thereby quickly moving any one of the multiple pre-set grooved rollers to the pressing position corresponding to the smooth roller. The entire process requires no disassembly of any parts, is simple to operate, and can be completed in a very short time, with minimal impact on the equipment's production efficiency and continuity. It achieves rapid connection of pressing processes for rope handles of different diameters, meeting the flexible production needs of small batches and multiple varieties. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a bag-making machine rope handle forming and bonding machine, including a rope handle bonding worktable 1. A support plate 2 is provided on the upper surface of one end of the rope handle bonding worktable 1. A paper guide roller 4 is rotatably mounted on the support plate 2 via a paper guide rod 3. Two corresponding fixing plates 6 are provided on the upper surface of the other end of the rope handle bonding worktable 1. A pressing rod 8 is rotatably mounted on the fixing plate 6 via a bearing 1. A smooth roller 9 is mounted on the pressing rod 8. An adjusting cylinder 16 is rotatably mounted on the fixing plate 6 via a bearing 2. The adjusting cylinder 16 is hollow inside. Two adjusting cylinders 16 are slidably equipped with adjusting rods 11. Several grooved rollers 12 are evenly arranged at equal intervals on the adjusting rods 11, and several semi-circular grooves 13 with different radii are evenly opened at equal angles on the grooved rollers 12. The grooved rollers 12 cooperate with the smooth rollers 9. A rope handle grooved roller adjusting assembly is provided inside the adjusting cylinders 16, and the rope handle grooved roller adjusting assembly is connected to the end of the adjusting rods 11. A driving assembly is provided on the fixed plate 6, and the driving assembly is connected to the adjusting cylinders 16 in a driving connection. The adjusting cylinders 16 are connected to the pressing rods 8 in a driving connection. The paper with the pre-attached rope handle passes around the guide roller 4 and is guided to the pressing area between the smooth roller 9 and one of the groove rollers 12. At this time, the geared motor 18 starts, driving the transmission gear 10 meshing with it through the drive gear 17, thereby rotating the adjusting cylinder 16. Since the two transmission gears 10 mesh with each other, the pressing rod 8 and the adjusting cylinder 16 rotate synchronously in opposite directions. The groove roller 12 and the smooth roller 9 in the pressing area rotate together, pressing the paper with the pre-attached rope handle passing between them. The rope handle is precisely embedded in the semi-circular groove 13 of the corresponding radius on the groove roller 12, and the fastening is completed under strong pressure. When it is necessary to produce paper bags with a different diameter rope handle, the operator does not need to disassemble any rollers, but can quickly switch by simply rotating the adjusting screw 20. The operator rotates the adjusting screw 20. Since the adjusting screw 20 is threadedly connected to the mounting bracket 19, the rotation will cause the adjusting screw 20 to move axially. The inner end of the adjusting screw 20 is connected to the circular groove at the end of the adjusting rod 11 through the bearing 3. Therefore, the axial movement of the adjusting screw 20 will directly push or pull the entire adjusting rod 11 to slide inside the adjusting cylinder 16. As the adjusting rod 11 moves axially, the multiple grooved rollers 12 installed at equal intervals on it also move. The operator moves the adjusting rod 11 to align the grooved roller 12 of the semi-circular groove 13 of the required radius with the pressing position of the smooth roller 9. When the target grooved roller 12 is in place, the switching is completed. The whole process is simple to operate, saves time, and has little impact on the production efficiency and continuity of the equipment. It is suitable for flexible production needs of small batches and multiple varieties.

[0023] Furthermore, the rope handle groove roller adjustment assembly is a guide block 15 set on the adjustment rod 11. The adjustment cylinder 16 is provided with an adjustment guide groove 14 that cooperates with the guide block 15. The end of the adjustment rod 11 is provided with a circular groove, and the inside of the circular groove is rotatably connected to the inner end of the adjustment screw 20 through a bearing 3. The fixing plate 6 is provided with a mounting bracket 19 corresponding to the adjustment screw 20. The adjustment screw 20 passes through the mounting bracket 19, and the adjustment screw 20 is threadedly connected to the mounting bracket 19.

[0024] Furthermore, the drive component is a geared motor 18 mounted on the fixed plate 6, and the geared motor 18 is fixedly connected to the fixed plate 6 via a connecting plate.

[0025] Furthermore, the output shaft end of the geared motor 18 is provided with a drive gear 17, and both the pressing rod 8 and the adjusting cylinder 16 are provided with transmission gears 10, and the two transmission gears 10 mesh with each other, with the drive gear 17 meshing with one of the transmission gears 10.

[0026] Furthermore, a molding gasket 23 is provided in the semi-circular groove 13. The molding gasket 23 can be made of wear-resistant or elastic material, which can protect the surface of the rope handle from scratches and increase the clamping force during pressing, making the fit more secure.

[0027] Furthermore, an anti-deviation film 5 is provided on the paper guide roller 4. The anti-deviation film 5 can increase the friction between the paper and the pre-attached rope handle, effectively preventing the paper from deviating during the feeding process.

[0028] Furthermore, a turntable 21 is provided at the outer end of the adjusting screw 20. The turntable 21 increases the rotation radius, making rotation easier.

[0029] Furthermore, a rotating rod 22 is provided at an eccentric position on the turntable 21. The rotating rod 22 allows the turntable 21 to be rotated more quickly.

[0030] The working principle of the bag making machine rope handle forming and bonding machine provided by this utility model is as follows: In use, the paper with the pre-attached rope handle passes around the guide roller 4 and is guided to the pressing area between the smooth roller 9 and one of the groove rollers 12. At this time, the geared motor 18 starts, driving the transmission gear 10 meshing with it through the drive gear 17, thereby rotating the adjusting cylinder 16. Since the two transmission gears 10 mesh with each other, the pressing rod 8 and the adjusting cylinder 16 rotate synchronously in opposite directions. The groove roller 12 located in the pressing area rotates together with the smooth roller 9, pressing the paper with the pre-attached rope handle passing between them. The rope handle is precisely embedded in the semi-circular groove 13 of the corresponding radius on the groove roller 12, and the tight bonding is completed under strong pressure. When it is necessary to produce paper bags with a rope handle of a different diameter, the operator does not need to disassemble any rollers, but only needs to rotate the adjusting screw 20 to achieve rapid bonding. Switching is performed by the operator rotating the adjusting screw 20. Since the adjusting screw 20 is threadedly connected to the mounting bracket 19, rotation will cause the adjusting screw 20 to move axially. The inner end of the adjusting screw 20 is connected to the circular groove at the end of the adjusting rod 11 through the bearing 3. Therefore, the axial movement of the adjusting screw 20 will directly push or pull the entire adjusting rod 11 to slide inside the adjusting cylinder 16. As the adjusting rod 11 moves axially, the multiple grooved rollers 12 installed at equal intervals on it also move. The operator moves the adjusting rod 11 to align the grooved roller 12 of the semi-circular groove 13 of the required radius with the pressing position of the smooth roller 9. When the target grooved roller 12 is in place, the switching is completed. The whole process is simple to operate, saves time, and has little impact on the production efficiency and continuity of the equipment, adapting to the flexible production needs of small batches and multiple varieties.
