Description

Technical Field

[0001] This utility model relates to the technical field of release paper sheets for paper bag making machines, and more particularly to a conveying device for conveying anti-tear and theft release paper sheets into the paper bag making machine. Background Technology

[0002] Currently, in the manufacturing process of takeout paper bags and other takeout tote bags, the paper handle with the handle rope needs to be glued to the bag body. Usually, the paper handle is glued on during the bag-making process. To enhance anti-theft functionality, some takeout paper bags also have a foldable anti-theft paper piece glued to the front of the paper handle. The back of this anti-theft paper piece is glued to the paper handle, while the front is coated with adhesive. Release paper is attached to the adhesive area, and it folds inside the bag or flips up along with the folded portion of the anti-theft paper piece. To load food into this paper bag, first fold up the folded portion of the anti-theft paper piece, then put the food into the bag. After securing the food, remove the release paper and fold the folded portion of the anti-theft paper piece to the other side of the bag, then glue it in place with adhesive. This completes the function of sealing the bag opening and preventing theft. To enhance the anti-theft performance of the paper bag, the applicant developed a new paper bag structure that replaces traditional anti-theft paper with a tear-resistant release liner attached to the bag. Once the tear-resistant release liner is sealed, opening the bag will only damage the release liner, and once damaged, it will be irreversible and unrepairable, reminding consumers that the paper bag has been opened after being sealed with food, thus achieving a high level of anti-theft performance.

[0003] In the aforementioned production of paper bags with handles, regardless of whether traditional tamper-evident paper strips or tear-resistant release liner strips are used, the process of attaching the release liner strip is necessary. Since the production equipment and processes for traditional paper bags (without tamper-evident or tear-resistant release liner strips) are already very mature and well-established, the traditional method for attaching the release liner strip is manual. This involves manually applying the release liner strip to the bag body using glue after bag making. This manual method is inefficient, labor-intensive, and each worker can only produce about 8 bags per minute. Furthermore, manually applying glue to the release liner strip cannot guarantee consistent glue application and placement, easily leading to quality problems and high waste during production. Additionally, to meet production and delivery requirements, sometimes an additional 24 employees are needed for this manual attachment process, resulting in high production costs.

[0004] In existing patent literature, there is no publicly available or technically available solution concerning the automated production of tamper-evident release liner sheets with release paper and foldable design on paper bag machines. Therefore, to avoid the shortcomings of the prior art, it is necessary to improve the existing technology to develop a conveying device that automatically transports the tamper-evident release liner sheets to the paper bag machine for synchronous pasting production. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a conveying device for conveying anti-tear and theft release paper sheets to the paper bag machine for production. This conveying device can realize the addition of anti-tear and theft release paper sheets to the paper bag machine for synchronous pasting on the basis of the original paper bag machine for producing handle paper bags, replacing the traditional manual pasting method, thereby achieving the purpose of reducing labor intensity, improving material safety, and improving product quality. The conveying device unwinds the tamper-evident release liner by placing it on the unwinding frame. Then, the alignment component guides the tamper-evident release liner to ensure that the two sides are aligned after folding. It then enters the folding component to fold the tamper-evident release liner into shape. After folding, it is conveyed to the cutting component and precisely cut into individual tamper-evident modules according to the markings on the tamper-evident release liner. Then, the pusher component pushes the individual tamper-evident modules into the conveying component, which delivers the cut individual tamper-evident modules to the corresponding position in the paper bag making machine for pasting.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a conveying device for conveying anti-tear and theft release paper sheets to a paper bag machine, including a handle attaching frame, an unwinding frame disposed on the handle attaching frame and having the anti-tear and theft release paper sheet roll wound on it for unwinding and output, a deviation correction component for conveying and correcting the output anti-tear and theft release paper sheets, a folding component for folding the anti-tear and theft release paper sheets after deviation correction, a cutting component for cutting the folded anti-tear and theft release paper sheets at a fixed distance to form individual anti-tear and theft modules, a pusher component for pushing the individual anti-tear and theft modules, and a conveying component for conveying the pushed anti-tear and theft modules to the paper bag machine.

[0007] Furthermore, the folding assembly includes an upper folding fixing frame and a lower folding fixing frame fixedly installed on the handle attaching machine frame and arranged vertically, a folding forming clamp plate installed between the upper folding fixing frame and the lower folding fixing frame and arranged vertically, a folding guide positioning plate installed on the lower folding fixing frame and inclined upward towards the folding forming clamp plate, and a folding guide roller fixedly installed on the handle attaching machine frame and located above the folding forming clamp plate.

[0008] Furthermore, the slitting assembly includes a servo roller mounted on the handle attaching frame and facing the folding guide roller, a cutter holder mounted on the handle attaching frame, a servo cutter mounted on the handle attaching frame and located above the cutter holder, and a tracking photocell mounted on the servo cutter for precise positioning and tracking of the marking points on the anti-tear release paper.

[0009] Furthermore, the correction assembly includes a correction servo roller mounted on the handle attaching machine frame and a correction positioning block mounted on the handle attaching machine frame and located at both ends of the correction servo roller to limit and transport the two sides of the anti-tear release paper sheet.

[0010] Furthermore, the pusher assembly includes a pusher fixing seat fixedly installed on the handle frame, and pushers installed on the pusher fixing seat and sequentially pushing the individual anti-tear and theft modules into the conveying assembly.

[0011] Furthermore, the conveying assembly includes a conveyor belt and a pressure roller located above the conveyor belt to press the anti-theft module onto the conveyor belt for conveying.

[0012] Furthermore, the aforementioned handle frame is also equipped with an unwinding conveyor roller located between the unwinding frame and the correction assembly.

[0013] Furthermore, the unwinding frame is equipped with an unwinding support back plate that supports and positions the back of the anti-tear and theft release paper roll.

[0014] In summary, the conveying device of this utility model, which transports anti-tear and burglar-proof release liner to the paper bag machine, can simultaneously convey and paste the anti-tear and burglar-proof release liner onto the paper bag machine, replacing the traditional manual pasting method. This achieves the goals of reducing labor intensity, improving material safety, and enhancing product quality. The conveying device unwinds the anti-tear and burglar-proof release liner by placing it on an unwinding rack. Then, a correction component guides the conveying and positioning of the release liner to ensure that the two sides are aligned after folding. It then enters the folding component to fold the release liner into two folds. After folding, it is conveyed to the cutting component and precisely cut into individual anti-tear and burglar-proof modules according to the markings on the release liner. A pusher component then pushes each individual module into the conveying component, which delivers the cut modules to the corresponding positions in the paper bag machine for pasting.

[0015] The effective effect of the conveying device that transports the anti-tear release paper to the paper bag machine is to achieve automatic conveying to the paper bag machine for pasting production and synchronous production speed, reduce the workload of workers, improve the production efficiency of anti-tear handle paper bags, and produce 78 anti-tear handle paper bags per minute, and only one worker is needed to package the anti-tear handle paper bags after bag making.

[0022] Example 1

[0023] This embodiment 1 describes a conveying device for conveying anti-tear and theft release paper sheets to a paper bag machine for production, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it includes a handle attaching machine frame 9, an unwinding frame 2 mounted on the handle attaching machine frame and unwinding the anti-tear release paper roll 1, a guide component 4 for conveying and correcting the output anti-tear release paper roll 3, a folding component 5 for folding the anti-tear release paper roll after correction, a cutting component 6 for cutting the folded anti-tear release paper roll at a fixed distance to form individual anti-tear modules 27, a pusher component 7 for pushing the individual anti-tear modules, and a conveying component 8 for conveying the pushed anti-tear modules to the paper bag machine. The conveying device that transports the anti-theft release paper to the paper bag machine achieves automated production of the anti-theft module through a series of processes including unwinding, alignment, folding, slitting, pusher, and conveying into the paper bag machine. Each process is implemented through components such as the unwinding frame, alignment roller, folding plate, cutter, pusher, and conveyor belt. These components are also linked by gears and signals with the paper bag machine to achieve synchronized production. The anti-theft module is conveyed to the glued area of ​​the paper bag in the paper bag machine for bonding, meaning the conveyor belt and other components are matched with the running speed of the paper bag machine. The conveying direction of the anti-theft module produced by this device is perpendicular to the conveying direction of the paper bag base paper in the paper bag machine, achieving the purpose of bonding the anti-theft module to the paper bag base paper to produce the entire handle paper bag.

[0024] In this embodiment 1, the folding assembly includes an upper folding fixing frame 10 and a lower folding fixing frame 11 fixedly installed on the handle attaching machine frame and arranged vertically, a folding forming clamping plate 12 installed between the upper folding fixing frame and the lower folding fixing frame and arranged vertically, a folding guide positioning plate 13 installed on the lower folding fixing frame and inclined upward towards the folding forming clamping plate, and a folding guide roller 14 fixedly installed on the handle attaching machine frame and located above the folding forming clamping plate. The upper and lower fixing frames are used to fix and install the vertically set folding forming clamps. The folding forming clamps are formed by bending one clamp to form two clamps on the left and right sides, with a gap between the two clamps to form the fold of the anti-tear and theft release paper. During folding, after unwinding and correction, the anti-tear and theft release paper is vertically conveyed upwards. The bottom corner of the folding guide positioning plate forms a folding seam with the center of the anti-tear and theft release paper. The two sides of the anti-tear and theft release paper gradually narrow inwards with the folding seam as the center of symmetry. Then, it is inserted from the bottom of the folding forming clamp to form the fold and the two sides after folding are aligned. The folded anti-tear and theft release paper is then conveyed by the folding guide roller into the slitting process.

[0025] In this embodiment 1, the slitting assembly includes a servo roller 15 mounted on the handle attaching frame and facing the folding guide roller, a cutter holder 16 mounted on the handle attaching frame, a servo cutter 17 mounted on the handle attaching frame and located above the cutter holder, and a tracking photoelectric sensor 18 mounted on the servo cutter for precise positioning and tracking of the markings on the anti-theft release liner. After the anti-theft release liner is folded and formed, it is conveyed onto the servo roller. The servo roller conveys the anti-theft release liner at a uniform speed. When the anti-theft release liner passes the position of the servo cutter, the tracking photoelectric sensor tracks the markings on the anti-theft release liner and controls the servo cutter to press down precisely to cut the anti-theft release liner, slitting it into individual anti-theft modules, thus completing the slitting process. The servo roller is set in the same direction as the folding guide roller.

[0026] In this embodiment 1, the correction assembly includes a correction servo roller 19 mounted on the handle attaching frame and correction positioning blocks 20 mounted on the handle attaching frame and located at both ends of the correction servo roller to limit and convey the two sides of the anti-tear and theft release liner. After the anti-tear and theft release liner is unwound, it enters the correction servo roller for conveying, and then the correction positioning blocks correct and position the two sides of the anti-tear and theft release liner, ensuring that the two sides of the anti-tear and theft release liner are aligned when it is folded, resulting in a good folding effect.

[0027] In this embodiment 1, the pusher assembly includes a pusher fixing seat 21 fixedly mounted on the handle attaching machine frame, and pushers 22 mounted on the pusher fixing seat to sequentially push the tamper-evident modules, cut into individual pieces, into the conveying assembly. Each tamper-evident module after cutting is pushed into the conveying assembly by the pusher; the pusher pushes the tamper-evident module into the conveying assembly once for each paper bag handle manufactured. The pusher has an open, I-shaped structure, which can fix each tamper-evident module and stably push it into the conveying assembly, achieving precise and stable pushing of the tamper-evident module to the designated position without deviation.

[0028] In this embodiment 1, the conveying assembly includes a conveyor belt 23 and a pressure roller 24 located above the conveyor belt, pressing the anti-theft module firmly onto the conveyor belt for conveying. The belt and pressure roller are conveyed proportionally by the belt and overlapped with the adhesive on the paper bag for bonding. When the anti-theft module enters the conveyor belt for conveying and enters the paper bag machine for synchronous production, the pressure roller presses, conveys, and positions the anti-theft module, ensuring that it is in a flat state and conveyed stably when it exits the conveyor belt and enters the paper bag machine.

[0029] In this embodiment 1, the attached handle frame is also equipped with an unwinding conveyor roller 25 located between the unwinding frame and the web guiding assembly. When the unwinding enters the web guiding assembly, the multiple unwinding conveyor rollers can achieve a stable and non-shaking output of the anti-tear and theft release sheet, improving the stability and tension of the conveying.

[0030] In this embodiment 1, the unwinding frame is provided with an unwinding support back plate 26 for supporting and positioning the back of the anti-tear and theft release paper roll. Since the anti-tear and theft release paper roll has a certain weight, the unwinding support back plate on the unwinding frame can provide a certain back support capacity for the anti-tear and theft release paper roll during unwinding, improving the stability of the anti-tear and theft release paper roll during unwinding and achieving a good unwinding effect.

[0031] In this embodiment 1, the conveying device for transporting tamper-evident release liner sheets to the paper bag machine can simultaneously attach tamper-evident release liner sheets to the paper bag machine, replacing the traditional manual attachment method. This achieves the goals of reducing labor intensity, improving material safety, and enhancing product quality. The conveying device unwinds the tamper-evident release liner sheets by placing them on an unwinding rack. Then, a correction component ensures the release liner sheets are aligned after folding. The sheets are then folded in half by a folding component, and finally conveyed to a cutting component for precise cutting into individual tamper-evident modules according to the markings on the release liner sheets. A pusher component then pushes each module into a conveying component, which delivers the cut modules to the corresponding positions on the paper bag machine for attachment.

[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
