Description

Technical Field

[0001] The utility model relates to the field of bag making machines, in particular to a paper bag sheet material stringing machine with a string body turned outward and reinforced. Background Art

[0002] In the production process of paper bags, the string threading process is a key step. Traditional string threading methods for paper bags have problems such as low efficiency and loose string threading. In particular, when the string body and the bag body are fixed by gluing, the traditional string body is directly fixed to the inner surface of the bag body's main sheet after stringing. Therefore, it is necessary to use a quick-drying glue to quickly fix the string body and the bag body to facilitate the subsequent process. Regardless of whether the subsequent folding piece is glued separately, after the bag is loaded with materials, the force-bearing surface between the string body and the bag body is mainly between the string body and the bag body's main sheet on both sides. However, due to the characteristics of quick-drying glue, its adhesion strength and aging resistance are poor, resulting in insufficient fixation between the string body and the bag body's main sheet. Especially after being placed for a long time, the rope is easy to fall off when the bag is bearing weight. In addition, when stringing bags of different sizes, it is difficult to flexibly adjust the rope removal position according to their size and the position of the string threading hole.

[0003] Therefore, a paper bag sheet material stringing machine with a rope body turned outward and reinforced is needed to solve the problem that the fixation between the rope body and the bag body main body sheet is not firm enough. Utility Model Content

[0004] The utility model aims at the shortcomings of the prior art and provides a paper bag sheet material stringing machine with a string body that is turned outward and reinforced.

[0005] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0008] The gluing device also includes a rope reinforcement device, which includes a reinforcement gluing head. The reinforcement gluing head corresponds to the upper surface of the outward-turned bag rope or the main bag body sheet. The gluing area of the outward-turned gluing head and the gluing area of the reinforcement gluing head both pass through the centerline of the bag rope threading hole in the y-axis direction, and are used to adhere the two sides of the bag rope to the folding piece and the main bag body sheet, respectively, when the bag is folded. The upper surface of the outward-turned bag rope refers to the gluing position on the bag rope. If the reinforcement gluing head 81 corresponds to the main bag body sheet, this position is located after the outward-turned bag rope is folded, where the side of the bag rope that is not attached to the folding piece contacts the main bag body sheet.

[0009] Preferably, the outward-turning gluing head for pre-gluing the folding piece is a quick-drying glue gluing head. The glue can dry quickly, so that the rope body and the folding piece of the bag body are quickly bonded, making it easy for the bag body and the rope body to enter the next process in a fixed state, thereby improving production efficiency.

[0010] Preferably, the gluing position of the reinforcement gluing head, the gluing position of the external gluing head, and the center line of the rope hole of the bag body are located on the same straight line in the y-axis direction. This ensures the accuracy of the glue application position, makes the connection between the rope body and the bag body more secure, and helps to increase the load-bearing capacity of the rope and bag.

[0011] Preferably, the rope reinforcing device is arranged on the rope threading device or downstream of the rope threading device.

[0012] Preferably, the rope body reinforcement device includes a gluing seat, the gluing seat is provided with a gluing adjustment guide rail extending along the x-axis direction, a gluing slider is slidably provided on the gluing adjustment guide rail, and the reinforcement gluing head is connected to the gluing slider.

[0013] Preferably, the gluing slider is provided with an adjusting nut, the adjusting nut thread is engaged with an adjusting screw extending in the x direction, and an adjusting hand wheel is installed at the end of the adjusting screw. The adjusting hand wheel can be used to conveniently adjust the position of the reinforcement gluing head to meet the gluing requirements of bags of different sizes.

[0014] Preferably, the outward-turning mechanism includes an outward-turning mounting beam extending along the x-axis and connected to an outward-turning power source. The outward-turning pusher slidably engages the outward-turning mounting beam and is capable of rising and falling relative to the outward-turning mounting beam. This structural design enables the outward-turning pusher to accurately push or clamp the bag rope passing through the rope threading hole to the side of the pre-glued flap of the bag body, ensuring smooth rope threading and gluing processes.

[0015] Preferably, the outward-turning mounting beam is connected to the outward-turning power source through a connecting rod, which is a rotating power source. One end of the connecting rod is hinged to the output end of the outward-turning power source, and the other end of the connecting rod is hinged to the rotating shaft fixed on the outward-turning mounting beam.

[0016] Preferably, at least one of the left and right rope-taking chucks is connected to an internal driving force source, which drives the left and right rope-taking chucks to move closer or farther apart to adjust the rope-taking position. This facilitates adjustment of the rope-taking position according to the bag size and the position of the rope-passing hole, thereby improving the versatility of the device.

[0017] Preferably, the rope-pulling mechanism further includes a rope-positioning member for positioning one end of the rope, with the other end of the rope being pulled out by a rope-pulling clamp connected to a translational force source. The rope-positioning member positions one end of the rope, while the rope-pulling clamp pulls out the other end, thereby ensuring the accuracy of the rope length.

[0018] Preferably, the internal driving force source includes left and right synchronous wheels and an internal pushing belt mounted on the synchronous wheels on both sides, and the left and right rope taking clamps are respectively connected to different front and rear sides of the internal pushing belt.

[0022] Preferably, the rope chuck and the rope threading mechanism are separately mounted on a rotating swing arm, with the rope threading member located below the rope chuck. The rope chuck and the rope threading mechanism may share a power source, and the rope threading mechanism may rotate along with the rope chuck. When the rope chuck grips the rope and rotates below the rope threading hole, the rope threading member is also located below the rope threading hole. Furthermore, when the bag size or the position of the rope threading hole changes, the internal driving force source may also synchronously adjust the rope threading member and the rope chuck.

[0023] Preferably, the rope cutting device is an ultrasonic cutting device, which can quickly and accurately cut the bag rope with a smooth cut, which is beneficial for the subsequent rope threading and gluing processes.

[0024] Preferably, the processing platform is equipped with an anti-deviating component for fixing the bag sheet by adsorption or pressure.

[0025] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0026] By setting up a rope reinforcement device, the rope is turned outward and then coated with reinforcement glue, so that both sides of the bag body and the rope body are in contact, and the glue between the rope body and the bag body main body sheet is stronger, which greatly increases the load-bearing capacity of the rope and bag.

[0027] In addition, the internal driving force source drives the left and right rope-taking clamps to move closer or away, and the rope-taking position can be flexibly adjusted according to the size of the bag body and the position of the rope hole, thereby improving the versatility and applicability of the equipment.

[0037] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] Paper bag sheet material stringing machine with rope outer folding reinforcement, such as Figure 1-5As shown, it includes a bag conveying device, and a rope threading device 3 is provided on the conveying path of the bag conveying device, which is characterized in that the rope threading device 3 includes a processing platform 31, a rope pulling mechanism 32, a rope cutting device 33, a rope rotating mechanism, a rope threading mechanism 36, and an eversion mechanism 38. The processing platform 31 is used to lay out the bag sheet 90, and a rope threading station is provided on the processing platform 31; the rope pulling mechanism 32 is arranged on both sides of the y-axis direction of the processing platform 31, and the rope pulling mechanism 32 includes a rope pulling clamp 321 movable along the x-axis direction, for pulling the bag rope to a preset length; the rope cutting device 33 is used to cut the bag rope pulled to a preset length; the rope rotating mechanism includes left and right rope taking clamps 34, the rope taking clamp 34 is connected to a clamp rotation power source 35, and the left and right rope taking clamps 34 are respectively close to the rope pulling clamp 321 and the rope cutting device 33 The bag rope is clamped at the bag body, and the chuck rotating power source 35 drives the rope taking chuck 34 to clamp the bag rope cut by the rope cutting device 33 and rotate it to the bottom of the bag body sheet 90, corresponding to the position of the bag body rope threading hole 97; the rope threading mechanism 36 includes a rope threading part 361, and the rope threading part 361 corresponds to the bag body rope threading hole 97 opened on the folding piece 96 on the outside of the bag body main sheet 93 on the processing platform 31. The rope threading part 361 clamps or pushes the bag rope end from the bottom of the bag body sheet 90 through the rope threading hole 97 and is above the bag body sheet 90; the outward turning mechanism 38 includes an outward turning pusher 381, which can move inward and outward to push the bag rope passing through the rope threading hole to the gluing position outside the rope threading hole 97, wherein the inward and outward movement can be a lateral movement, a downward pressure or a folding line movement of rising, lateral movement, and downward pressure, or a hinge-like flipping movement.

[0040] like Figure 6-7 As shown, a gluing device 7 is also provided, which includes an outward-turned gluing head for pre-gluing the gluing portion of the bag body folding piece 96 corresponding to the outer side of the rope threading hole 97, and the gluing area of the outward-turned gluing head passes through the center line of the bag body rope threading hole 97 in the y-axis direction;

[0041] The gluing device 7 also includes a rope reinforcement device 8, which includes a reinforcement gluing head 81. The reinforcement gluing head 81 corresponds to the upper surface of the bag rope or the main bag sheet 93. The gluing area of the reinforcement gluing head 81 passes through the centerline of the bag rope threading hole 97 in the y-axis direction, and is used to adhere the two sides of the bag rope to the folding piece 96 and the main bag sheet 93 respectively when the bag is folded. The upper surface of the bag rope refers to the gluing position on the bag rope. If the reinforcement gluing head 81 corresponds to the main bag sheet 93, this position is the position where the side of the bag rope not attached to the folding piece contacts the main bag sheet 93 after the fold.

[0042] The outward-turning gluing head for pre-gluing the folding piece 96 is a quick-drying glue gluing head. The glue can dry quickly, so that the rope body and the bag folding piece 96 can be quickly bonded, making it easy for the bag body and the rope body to enter the next process in a fixed state, thereby improving production efficiency.

[0043] In one embodiment of the invention, the gluing position corresponding to the reinforcement gluing head 81, the gluing position corresponding to the outward-turned gluing head, and the center line of the rope hole 97 of the bag body are located on the same straight line in the y-axis direction. This ensures the accuracy of the glue application position, making the connection between the rope body and the bag body more secure, which is beneficial to increasing the load-bearing capacity of the rope and the bag. The rope body can be fixed by local gluing. If the bag body is to be folded later, the outward-turned gluing head can only glue the part corresponding to the rope body, and additionally glue the folding part close to the entire folding part to fix the bag body folding. As another embodiment, the outward-turned gluing head can also directly glue the entire folding.

[0044] The rope reinforcing device 8 is arranged on the rope threading device 3 or located downstream of the rope threading device 3 .

[0045] The rope reinforcement device 8 includes a gluing seat 82 , on which a gluing adjustment guide rail 83 extending along the x-axis is provided. A gluing slider 84 is slidably provided on the gluing adjustment guide rail 83 , and the reinforcement gluing head 81 is connected to the gluing slider 84 .

[0046] The gluing slider 84 is provided with an adjusting nut 85, which is threadedly matched with an adjusting screw 86 extending in the x direction, and an adjusting handwheel 87 is installed at the end of the adjusting screw 86. The position of the reinforcement gluing head 81 can be easily adjusted by adjusting the handwheel 87 to adapt to the gluing requirements of bags of different sizes.

[0047] like Figure 3-5 As shown, the outward-turning mechanism 38 includes an outward-turning mounting beam 382 extending along the x-axis and connected to an outward-turning power source 383. An outward-turning pusher 381 slidably engages with the outward-turning mounting beam 382 and is capable of rising and falling relative to the outward-turning mounting beam 382. This structural design enables the outward-turning pusher 381 to accurately push or clamp the bag rope passing through the rope threading hole to the side of the pre-glued folding piece 96 of the bag body, ensuring smooth rope threading and gluing processes.

[0048] The outward-turning mounting beam 382 is connected to the outward-turning power source 383 through a connecting rod 384. The outward-turning power source 383 is a rotational power source. One end of the connecting rod 384 is hinged to the output end of the outward-turning power source 383, and the other end of the connecting rod 384 is hinged to the rotating shaft fixed on the outward-turning mounting beam 382.

[0049] At least one of the left and right rope-taking chucks 34 is connected to an internal driving force source 37, which drives the left and right rope-taking chucks 34 to move toward or away from each other to adjust the rope-taking position. This facilitates adjustment of the rope-taking position according to the bag size and the location of the rope-taking hole, thereby improving the versatility of the device.

[0050] The rope-pulling mechanism 32 also includes a rope-positioning member 322 for positioning one end of the rope. The other end of the rope is pulled out by a rope-pulling clamp 321, which is connected to a translational force source 323. The rope-positioning member 322 positions one end of the rope, while the rope-pulling clamp 321 pulls out the other end, ensuring the accuracy of the rope length.

[0051] The internal driving force source 37 includes left and right synchronous wheels 371 and an internal pushing belt 372 sleeved on the two synchronous wheels 371 . The left and right rope taking clamps 34 are respectively connected to different front and rear sides of the internal pushing belt 372 .

[0052] An inward push mounting seat 373 is provided below the processing platform 31 . The inward push mounting seat 373 is slidably provided on an inward push slide rail 375 via an inward push slider 374 . The chuck rotation power source 35 is installed on the inward push mounting seat 373 .

[0053] The chuck rotation power source 35 is connected to a rotating swing arm 376 that is rotatable relative to the inward push mounting seat 373 .

[0054] The left and right inner push mounting seats 373 are connected to different front and rear sides of the inner push belt 372 through clamping blocks 377 respectively.

[0055] The rope chuck 34 and rope threading mechanism 36 are separately mounted on a rotating swing arm 376, with the rope threading member 361 located below the rope chuck 34. The rope chuck 34 and the rope threading mechanism 36 can share a common power source, allowing the rope threading mechanism 36 to adjust synchronously with the adjustment of the rope chuck 34. When the rope chuck grasps the rope and rotates below the rope threading hole, the rope threading member also moves below the rope threading hole. Furthermore, if the bag size or the position of the rope threading hole changes, the internal driving force source can also synchronously adjust the rope threading member and the rope chuck.

[0056] The rope cutting device 33 is an ultrasonic cutting device. The ultrasonic cutting device can quickly and accurately cut the bag rope, and the cut is smooth, which is beneficial to the subsequent rope threading and gluing process.

[0057] The processing platform 31 is equipped with an anti-drifting component 311 that secures the bag sheet by suction or pressure. After being conveyed by the bag conveyor, the bag sheet 90 is laid flat on the processing platform 31 and secured by the anti-drifting component 311 to prevent it from shifting during processing. The anti-drifting component 311 can be a suction head or plate with a nozzle below the bag sheet, or a pressure plate or other object above the bag sheet that can hold the bag sheet in place.

[0058] Working principle:

[0059] After the bag sheet 90 is laid flat on the processing platform 31 , the hand rope positioning member 322 of the rope pulling mechanism 32 positions one end of the hand rope, and the rope pulling clamp 321 pulls the other end of the hand rope to a preset length under the drive of the translational force source 323 .

[0060] The rope cutting device 33 pulls out the bag rope to a preset length and cuts it. The rope cutting device 33 can be a traditional knife, scissors, or hot cutter. As one possible implementation, the rope cutting device 33 is an ultrasonic cutting device, which can quickly and accurately cut the bag rope without problems such as sticking or uneven cuts. The left and right rope chucks 34 of the rope rotating mechanism first clamp the ends of the bag rope. Driven by the chuck rotation power source 35, the bag rope cut by the rope cutting device 33 is clamped and rotated to the position below the bag body sheet 90 corresponding to the bag body rope hole 97. Simultaneously, the internal driving force source 37 adjusts the position of the left and right rope chucks 34 according to the bag body size and the rope hole position. The string threading member 361 of the string threading mechanism 36 corresponds to the string threading hole 97 defined in the folding piece 96 on the outside of the bag body sheet 93 on the processing platform 31. The string threading member 361 clamps or pushes the end of the bag string through the string threading hole 97 from below the bag body sheet 90 and onto the top of the bag body sheet 90. The clamping method involves clamping the bag string from below the bag body and feeding it upward. In this method, the string threading member 361 can choose to pass through the string threading hole 97 or not, simply feeding the ends of the string on both sides to the top of the bag body sheet. The pushing method involves the string threading member 361 pushing the string below the string threading hole 97 from bottom to top. The string threading member 361 carries the string through the string threading hole 97 in a partially folded state. After passing through the string threading hole, the end of the string, due to insufficient length, naturally passes through the string threading hole 97, appearing upright or inwardly tilted.

[0061] Driven by the outward-turning power source 383, the outward-turning pusher 381 of the outward-turning mechanism 38 pushes the end of the bag string, which has passed through the string threading hole, to the side of the bag body's pre-glued flap 96. The outward-turning gluing head of the gluing device 7 pre-applies quick-drying glue to the area of the bag body flap 96 corresponding to the string threading hole 97, securing the bag string to the flap 96 and facilitating subsequent operations. The other side of the bag string can then be secured to the main bag body sheet with slow-drying reinforcement glue, ensuring greater adhesion and durability to the bag body's primary stress-bearing surface.

[0062] The reinforcement glue head 81 of the rope reinforcement device 8 applies glue to the upper surface of the outward-turned bag rope or the main bag sheet 93 to ensure a secure connection between the rope and the bag. Using the reinforcement glue to additionally reinforce the other side of the bag rope makes the primary stress-bearing surface of the connection between the rope and the bag more secure and durable. This localized glue application saves glue costs, ensures sufficient glue in that area, and accurately applies glue, thereby improving the bag yield rate.
