Description

Technical Field

[0001] The present invention belongs to the technical field of hand-held paper bags, and particularly relates to a production device and production process for hand-held paper bags. Background Art

[0002] The production process of hand-held paper bags includes printing, laminating, surface finishing, die-cutting and box gluing of paper; among them, the laminating process of hand-held paper bags is the most important. After laminating, the hand-held paper bags have the functions of waterproofing and stain resistance, and the patterns printed on the paper bags can be maintained for a longer time and look more beautiful in color; after the hand-held bags are laminated, the film can protect the paper from wear and tear, making the printed content not easily damaged, thereby extending the service life of the paper hand-held bags; secondly, it can increase the bearing capacity of the paper and enhance the load-bearing capacity of the hand-held bags.

[0003] In the prior art, during the printing process of hand-held paper bags, in order to avoid the phenomenon of back rubbing and soiling caused by the ink on the printed sheet not being dry yet and piling up, powder is often sprayed on the surface of the printed sheet to form an isolation layer, which is conducive to the air flow between the printed sheets and speeds up the drying of the ink. Spraying powder can not only effectively prevent back rubbing and soiling of the printed sheet, but also reduce the friction between the printed sheets during paper collection, which helps to collect the paper neatly. For small hand-held paper bag production factories, before laminating, workers often use pure cotton towels to wipe the surface of the paper, but often due to excessive wiping force, the printed surface of the paper is scratched, and due to too light wiping force, the dust on the paper surface cannot be cleaned thoroughly; during the laminating process, the dust remaining on the paper surface blocks between the covered film and the paper, which not only reduces the adhesion effect of the film, but also generates air in the film covered on the paper surface, thus causing quality accidents such as demolding and blistering of the covered film products, reducing the quality of the laminated products, and further resulting in the limitations of the prior art.

[0004] In view of this, the present invention proposes a production device and production process for hand-held paper bags, which solve the above technical problems. Summary of the Invention

[0017] A production process of a hand-held paper bag shown in the present invention is applicable to the above-mentioned hand-held paper bag production equipment; the steps of the process are as follows:

[0018] S1: First, the paper for making the hand-held paper bag is printed by a printing machine, and then the printed surface of the printed paper is evenly sprayed with plant starch and stacked and left standing to dry the printed surface. When it is necessary to laminate the printed paper, the staff places the stacked paper on the feeding mechanism and cleans the paper on the top layer of the stack. The feeding mechanism sends the paper to the dust removal mechanism.

[0019] S2: When the top layer of paper is sent to the previous dust removal plate, the previous electric push rod pushes the previous dust removal plate to contact the paper. When the surface of the previous dust removal plate is about to be covered with dust, the latter electric push rod pushes the latter dust removal plate to contact the printed surface of the paper. At this time, the previous electric push rod pulls the previous dust removal plate to rise, and the driving motor pulls the U-shaped scraper through the steel wire rope to scrape off the dust on the surface of the dust removal plate.

[0020] S3: After the current dust removal plate is cleaned, control the electromagnet to be energized so that the electromagnet adsorbs the scraper, and the scraper is reset under the action of the suction force of the electromagnet. At this time, the previous electric push rod pushes the previous dust removal plate to descend and contact the printed surface of the paper. At this time, the latter dust removal plate rises and is cleaned, and so on until all the papers are laminated.

[0021] S4: Before laminating the printed paper, first adjust the scraping angle of the scraping blade on the dust removal belt by rotating the mounting rod. When the printed surface of the top layer of paper slides into contact with the lower end surface of the dust removal belt, start the servo motor so that the servo motor drives the dust removal belt through the rotating shaft. As the feeding mechanism continuously conveys the paper, the dust will be blocked on one side of the dust removal belt and continuously accumulate in the dust storage groove, and the transmission of the dust belt causes the dust removal belt to drive the dust in the dust storage groove to fall from the upper end of the machine body.

[0022] S5: The part of the dust removal belt passing over the machine body contacts the scraping blade, so that the scraping blade scrapes the dust on the blocking surface of the dust removal belt and in the dust storage groove, so that the dust adhering to the blocking surface of the dust removal belt and the dust storage groove is scraped off by the scraping blade. At this time, the paper after dust removal is conveyed by the feeding mechanism to the laminating mechanism for lamination.

[0023] S6: After the film coating is completed, the staff first perform surface finishing on the film-coated paper through processes such as bronzing, UV coating, and varnishing, then perform die-cutting on the finished paper, then paste the die-cut paper into bags, and finally punch holes and thread ropes through the pasted paper bags to obtain the required hand-held paper bags.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. In the paper bag film coater used in the present invention, through the setting of the dust removal mechanism, the dust removal mechanism can handle and collect the dust on the printing surface of the paper, reducing the dust on the printing surface of the paper, improving the adhesion effect between the film and the paper, and improving the quality of the film-coated product; moreover, there is no need for staff to wipe the stacked paper before film coating, reducing the labor intensity of the staff and improving the production efficiency.

[0026] 2. In the paper bag film coater used in the present invention, through the setting of at least two dust removal plates, the dust removal plates can alternately block the dust on the printing surface of the paper, so that the dust cleaning module can clean the dust removal plates without stopping the operation of the entire device, thereby improving the film coating efficiency of the entire film coating device and effectively improving the actual application effect of the present invention.

[0027] 3. In the paper bag film coater used in the present invention, through the setting of the dust storage tank, the dust can enter the dust storage tank and be taken out of the machine body driven by the dust storage tank, thereby improving the effect of the dust removal belt on driving the dust, accelerating the separation of the dust from the paper and the upper end of the machine body, effectively improving the dust removal effect of the dust removal belt, and further improving the actual application effect of the present invention.

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] As Figures 1 to 5 shown, a hand-held paper bag production device of the present invention includes a paper bag laminating machine; the laminating machine further includes a machine body 1, a laminating mechanism, a feeding mechanism and a controller; the laminating mechanism and the feeding mechanism are installed above the machine body 1; the laminating mechanism is used to cover a film on the printed surface of the paper; the feeding mechanism is used to convey the paper to the laminating mechanism; the controller is used to control the automatic operation of the entire paper bag laminating machine;

[0037] A dust removal mechanism is provided between the laminating mechanism and the feeding mechanism; the dust removal mechanism is used to remove the dust remaining on the printed surface of the paper;

[0038] A dust cleaning module is provided at the lower end of the dust removal mechanism; the dust cleaning module is used to clean and collect the dust adhering to the surface of the dust removal mechanism;

[0039] In the prior art, it is necessary for workers to wipe the stacked papers before laminating to remove the dust on the printed surface of the papers. On the one hand, it increases the labor intensity of the workers and reduces the production efficiency. On the other hand, due to the workers' negligence or excessive powder spraying on the printed surface of the papers, the papers are not wiped clean, resulting in the dust remaining on the paper surface being located between the covered film and the paper during the laminating process. This not only reduces the adhesion effect of the film, but also generates air in the film covered on the paper surface, thus causing quality accidents such as demolding and blistering of the covered film products and reducing the quality of the laminated products;

[0040] During operation, the staff stack the printed paper on the feeding mechanism with the printed side of the stacked paper facing up. The feeding mechanism conveys the stacked paper one by one to the film laminating mechanism. At this time, the paper slides side by side along the upper end of the machine body 1 under the action of the feeding mechanism. When the paper slides to the dust removing mechanism, the dust removing mechanism removes the dust remaining on the printed side of the paper. The paper with the dust removed is conveyed by the feeding mechanism to the film laminating mechanism, and the film on the film laminating mechanism covers the paper. At this time, the film laminating mechanism presses and cuts the film covering the surface of the paper, and finally completes the film lamination of the paper. As the dust removing mechanism removes the dust, the dust will continuously accumulate at the dust removing mechanism. At this time, the dust cleaning module will clean and collect the dust accumulated at the dust removing mechanism, so that the dust removing mechanism can stably and effectively remove the dust on the surface of the paper.

[0041] Through the setting of the dust removing mechanism in the present invention, the dust removing mechanism can process and collect the dust on the printed side of the paper, reduce the dust on the printed side of the paper, improve the adhesion effect between the film and the paper, and improve the quality of the product after film lamination. Moreover, it is not necessary for the staff to wipe the stacked paper before film lamination, which reduces the labor intensity of the staff and improves the production efficiency.

[0042] As an implementation manner of the present invention;

[0043] The dust removing mechanism includes a mounting frame 2 and a dust removing plate 21. The lower end of the mounting frame 2 is installed with an electric push rod 22. The lower end of the electric push rod 22 is fixedly installed with a dust removing plate 21. The dust cleaning module is installed at the lower end of the dust removing plate 21. During operation, the staff wipe the topmost paper of the stacked paper. When the feeding mechanism slides the topmost paper along the upper end of the machine body 1 to the dust removing mechanism, the topmost paper is located at the lower end of the dust removing plate 21. At this time, the controller controls the electric push rod 22 to extend, so that the dust removing plate 21 contacts the topmost paper under the push of the electric push rod 22, and the printed side of the topmost paper slides relative to the lower end surface of the dust removing plate 21. As the feeding mechanism continues to transport, the dust removing plate 21 blocks the dust on the printed side of the next paper. After the film lamination of the stacked paper is completed, the controller controls the electric push rod 22 to contract. At this time, the user cleans the dust accumulated at the upper end of the machine body 1, and the controller controls the dust cleaning module to clean the dust adhered to the surface of the dust removing plate 21.

[0044] The dust removal plate 21 is made of silica gel material, and the lower end of the dust removal plate 21 is made of PE material; the number of the dust removal plates 21 is at least two; at least two of the dust removal plates 21 are arranged in parallel; during operation, the dust removal plate 21 is made of silica gel material, so that the dust adhesion effect of the dust removal plate 21 made of silica gel material on the blocked dust is stronger, so that the blocked dust can adhere to the blocking surface of the dust removal plate 21. Since the PE material feels like wax and is smooth, by setting the lower end of the dust removal plate 21 to be made of PE material, the friction between the lower end of the dust removal plate 21 and the printing surface of the paper is reduced, so that the wear caused by the lower end of the dust removal plate 21 to the paper is weakened, and the quality of the printing surface of the paper is improved. And by setting the dust removal plate 21 to be at least two, when the surface of the previous dust removal plate 21 is about to be covered with dust, the controller controls the latter electric push rod 22 to push the latter dust removal plate 21 to contact the printing surface of the paper, and the controller controls the previous electric push rod 22 to pull the previous dust removal plate 21 to rise, and controls the dust cleaning module to clean and collect the dust adhered to the surface of the dust removal plate 21. After the previous dust removal plate 21 is cleaned, the controller controls the previous dust removal plate 21 to descend and contact the printing surface of the paper. At this time, the latter dust removal plate 21 rises, and so on; through the setting of at least two dust removal plates 21 in the present invention, the dust removal plates 21 can alternately block the dust on the printing surface of the paper, so that the dust cleaning module can clean the dust removal plates 21 without stopping the operation of the whole device, thereby improving the film laminating efficiency of the whole film laminating device and effectively improving the practical application effect of the present invention.

[0045] The dust cleaning module includes a U-shaped scraping plate 23; the scraping plate 23 is slidably installed at the lower end of the dust removal plate 21; a driving motor 24 is installed on one side of the mounting frame 2; the output shaft of the driving motor 24 is fixedly connected to the scraping plate 23 through a steel wire rope 25; an electromagnet 26 is installed at one end of the dust removal plate 21 away from the driving motor 24; during operation, when the controller controls the electric push rod 22 to pull the dust removal plate 21 to rise, the controller controls the driving motor 24 to pull the U-shaped scraping plate 23 to slide along the surface of the dust removal plate 21 through the steel wire rope 25, so that the scraping plate 23 scrapes off the dust adhered to the surface of the dust removal plate 21, so that the dust adhered to the surface of the dust removal plate 21 falls onto the lower end surface of the U-shaped scraping plate 23. When the scraping plate 23 reaches the other end of the dust removal plate 21 under the pull of the steel wire rope 25, the controller controls the driving motor 24 to stop and controls the electromagnet 26 to be energized, so that the electromagnet 26 adsorbs the scraping plate 23, so that the scraping plate 23 is reset under the suction force of the electromagnet 26. When the dust accumulation amount on the lower end surface of the scraping plate 23 is relatively large, the staff cleans the dust accumulated on the lower end surface of the scraping plate 23, so as to ensure the continuous use of the scraping plate 23.

[0046] As another implementation manner of the present invention;

[0047] The dust removal mechanism includes a rotating shaft 3 and a dust removal belt 31; the number of the rotating shafts 3 is two; the two rotating shafts 3 are respectively installed on both sides of the machine body 1; the dust removal belt 31 is sleeved on the two rotating shafts 3; a servo motor 32 is installed on one side of the machine body 1; the output end of the servo motor 32 is fixedly connected to the rotating shaft 3; the powder cleaning module is installed on one side of the machine body 1, and the powder cleaning module is in sliding contact with the dust removal belt 31; during operation, when the feeding mechanism slides the wiped topmost paper along the upper end of the machine body 1 to the dust removal mechanism, the printing surface of the topmost paper is in sliding contact with the lower end surface of the dust removal belt 31. At this time, the controller controls the servo motor 32 to drive the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the dust removal belt 31 to drive, so that the dust removal belt 31 blocks the dust on the printing surface of the next paper. And as the dust removal belt 31 drives, the dust accumulated on one side of the dust removal belt 31 falls from one side of the machine body 1 under the drive of the dust removal belt 31, and the dust adhering to the surface of the dust removal belt 31 is removed by the powder cleaning module, so that the dust falls from the surface of the dust removal belt 31.

[0048] The powder cleaning module includes an L-shaped scraping blade 33; the scraping blade 33 is fixedly installed on one side of the machine body 1; the scraping blade 33 is in sliding contact with the outer wall of the dust removal belt 31; during operation, the dust removal belt 31 drives the dust to fall from the machine body 1. At this time, the part where the dust removal belt 31 crosses the machine body 1 contacts the scraping blade 33, so that the scraping blade 33 scrapes the blocking surface and the lower end surface of the dust removal belt 31, so that the dust adhering to the blocking surface and the lower end surface of the dust removal belt 31 is separated from the blocking belt under the scraping of the scraping blade 33. As the scraping blade 33 continuously scrapes the dust removal belt 31, the scraping surface of the scraping blade 33 for scraping the dust removal belt 31 adheres to dust. When there is more dust adhering to the scraping surface of the scraping blade 33, the staff uses tools to clean the dust adhering to the surface of the scraping blade 33, so as to improve the use effect of the scraping blade 33.

[0049] An installation rod 34 is installed on one side of the machine body 1; a groove 341 is formed on the surface of the installation rod 34; the scraping blade 33 is slidably connected in the groove 341; the scraping blade 33 is fixedly connected to the bottom of the groove 341 through a spring 342; during operation, when installing the installation rod 34, first make the scraping surface of the scraping blade 33 contact the dust removal belt 31, push the installation rod 34, so that the scraping blade 33 compresses the spring 342 and enters the groove 341 under the block of the dust removal belt 31, and then install the installation rod 34. At this time, the scraping blade 33 abuts against the dust removal belt 31 under the restoring force of the spring 342, so as to make the scraping force of the scraping blade 33 on the dust on the surface of the dust removal belt 31, avoid the dust adhering to the surface of the dust removal belt 31 and being difficult to fall off in humid rainy weather, and further improve the scraping effect of the scraping blade 33 on the dust removal belt 31, so that the actual application effect of the present invention is effectively improved.

[0050] One side of the body 1 is fixedly connected with a straight rod 4; the mounting rod 34 is cylindrical; the mounting rod 34 is rotatably connected to the straight rod 4; one end of the straight rod 4 away from the body 1 is provided with a limiting rod 41; the surface of the mounting rod 34 is circumferentially provided with a limiting groove 42; the limiting rod 41 passes through the straight rod 4 and is slidably connected in the limiting groove 42; during work, during the installation process of the mounting rod 34, first rotatably connect the mounting rod 34 in the straight rod 4. At this time, the scraping blade 33 contacts the powder removing belt 31 and the included angle between the two is the smallest. By rotating the mounting rod 34, the mounting rod 34 drives the scraping blade 33 to rotate, so that the scraping blade 33 slides along the powder removing belt 31. At this time, the included angle between the scraping blade 33 and the powder removing belt 31 increases, and the scraping blade 33 continuously compresses the spring 342 into the groove 341 under the block of the powder removing belt 31. When the included angle between the scraping blade 33 and the powder removing belt 31 reaches the requirement, at this time, the limiting groove 42 is aligned with the limiting rod 41. By pushing the limiting rod 41, the limiting rod 41 is inserted into the limiting groove 42 to limit the mounting rod 34; through the mutual cooperation between the straight rod 4 and the mounting rod 34 of the present invention, the mounting rod 34 is rotated, so as to adjust the included angle between the scraping blade 33 and the powder removing belt 31, thereby adjusting the scraping force and scraping effect of the scraping blade 33 on the dust on the surface of the powder removing belt 31. On rainy days, the scraping force of the scraping blade 33 on the powder removing belt 31 is increased, and the scraping effect on the dust with increased adhesiveness is improved. On dry sunny days, the scraping force of the scraping blade 33 on the powder removing belt 31 is reduced, the wear of the scraping blade 33 on the powder removing belt 31 is reduced, the service life of the powder removing belt 31 is improved, and the actual application effect of the present invention is effectively improved.

[0051] A dust storage groove 311 is provided on the outer wall of the powder removing belt 31; during work, as the feeding mechanism continuously conveys the paper, the dust is continuously blocked by the powder removing belt 31, so that the blocked dust continuously accumulates in the dust storage groove 311, and the dust storage groove 311 moves with the powder removing belt 31, so that the dust in the dust storage groove 311 moves synchronously under the block of the groove wall of the storage groove until the dust storage groove 311 drives the dust therein to cross the body 1, and the dust falls from the dust storage groove 311. And as the dust storage groove 311 contacts the scraping blade 33, the scraping blade 33 enters the dust storage groove 311 under the elastic force of the spring 342, so that the scraping blade 33 scrapes off the dust in the dust storage groove 311; through the setting of the dust storage groove 311 of the present invention, the dust can enter the dust storage groove 311 and be separated from the body 1 under the drive of the dust storage groove 311, so that the effect of the powder removing belt 31 on driving the dust is improved, the dust is accelerated to be separated from the paper and the upper end of the body 1, the powder removing effect of the powder removing belt 31 is effectively improved, and the actual application effect of the present invention is further improved.

[0052] The present invention shows a production process of a hand-held paper bag, which is applicable to the above-mentioned hand-held paper bag production equipment; the steps of the process are as follows:

[0053] S1: First, print the paper for making the hand-held paper bag through a printing press, then evenly spray plant starch on the printed surface of the printed paper, stack and let it stand still to dry the printed surface. When it is necessary to laminate the printed paper, the staff places the stacked paper on the feeding mechanism, and cleans the paper on the top layer of the stack. The feeding mechanism sends the paper to the dust removal mechanism;

[0054] S2: When the top layer of paper is sent to the previous dust removal plate 21, the previous electric push rod 22 pushes the previous dust removal plate 21 to contact the paper. When the surface of the previous dust removal plate 21 is about to be covered with dust, the latter electric push rod 22 pushes the latter dust removal plate 21 to contact the printed surface of the paper. At this time, the previous electric push rod 22 pulls the previous dust removal plate 21 to rise, and the drive motor 24 pulls the U-shaped scraper 23 through the steel wire rope 25 to scrape off the dust on the surface of the dust removal plate 21;

[0055] S3: After the current dust removal plate 21 is cleaned, control the electromagnet 26 to be energized, so that the electromagnet 26 adsorbs the scraper 23, so that the scraper 23 resets under the suction force of the electromagnet 26. At this time, the previous electric push rod 22 pushes the previous dust removal plate 21 to descend and contact the printed surface of the paper. At this time, the latter dust removal plate 21 rises and is cleaned, and so on, until all the papers are laminated;

[0056] S4: Before laminating the printed paper, first adjust the scraping angle of the scraping blade 33 on the dust removal belt 31 by rotating the mounting rod 34. When the printed surface of the top layer of paper slides into contact with the lower end surface of the dust removal belt 31, start the servo motor 32, so that the servo motor 32 drives the dust removal belt 31 to drive through the rotating shaft 3. As the feeding mechanism continuously conveys the paper, the dust will be blocked on one side of the dust removal belt 31 and continuously accumulate in the dust storage tank 311. The transmission of the dust belt makes the dust removal belt 31 drive the dust in the dust storage tank 311 to fall from the upper end of the machine body 1;

[0057] S5: The part of the dust removal belt 31 that crosses the machine body 1 contacts the scraping blade 33, so that the scraping blade 33 scrapes the dust on the blocking surface of the dust removal belt 31 and in the dust storage tank 311, so that the dust adhering to the blocking surface of the dust removal belt 31 and at the dust storage tank 311 is scraped off by the scraping blade 33. At this time, the dust-removed paper is conveyed by the feeding mechanism to the laminating mechanism for lamination;

[0058] S6: After laminating, the staff first performs surface finishing on the laminated paper through processes such as bronzing, UV, and varnishing, then performs die-cutting processing on the finished paper, then pastes the die-cut paper into a bag, and finally punches and strings the pasted paper bag to obtain the required hand-held paper bag.

[0059] The specific working process is as follows:

[0060] The staff stacks the printed paper on the feeding mechanism, with the printed side of the stacked paper facing up, and the feeding mechanism conveys the stacked paper to the film laminating mechanism one by one. At this time, the paper slides side by side along the upper end of the machine body 1 under the action of the feeding mechanism. When the paper slides to the dust removing mechanism, the dust removing mechanism removes the dust remaining on the printed side of the paper. The paper with the removed dust is conveyed by the feeding mechanism to the film laminating mechanism, so that the film on the film laminating mechanism covers the paper. At this time, the film laminating mechanism presses and cuts the film covering the surface of the paper, and finally completes the film lamination of the paper. As the dust removing mechanism removes the dust, the dust will continuously accumulate at the dust removing mechanism. At this time, the dust cleaning module will clean and collect the dust accumulated at the dust removing mechanism, so that the dust removing mechanism can stably and effectively remove the dust on the paper surface. The staff wipes the topmost paper of the stacked paper. When the feeding mechanism slides the topmost paper along the upper end of the machine body 1 to the dust removing mechanism, the topmost paper is located below the dust removing plate 21. At this time, the controller controls the electric push rod 22 to extend, so that the dust removing plate 21 contacts the topmost paper under the push of the electric push rod 22, and the printed side of the topmost paper slides relative to the lower end surface of the dust removing plate 21. As the feeding mechanism continues to transport, the dust removing plate 21 blocks the dust on the printed side of the next paper. After the film lamination of the stacked paper is completed, the controller controls the electric push rod 22 to contract. At this time, the user cleans the dust accumulated on the upper end of the machine body 1, and the controller controls the dust cleaning module to clean the dust adhering to the surface of the dust removing plate 21.

[0061] To verify the film laminating efficiency and film laminating effect of the paper bag film laminating machine manufactured in the present invention, the following experiments are now carried out:

[0062] A comparative experiment is carried out between the paper bag film laminating machine of the present invention and the commercially available paper bag film laminating machine. By measuring the number of papers laminated by the paper bag film laminating machine of the present invention and the commercially available paper bag film laminating machine within the same time, the papers are required for the production of large folio handbags, and the papers laminated by the paper bag film laminating machine of the present invention and the papers laminated by the commercially available paper bag film laminating machine are extracted for comparison and observation, so as to distinguish the film laminating effects of the two paper bag film laminating machines. And in order to ensure the accuracy of the experimental data, 5 groups of comparative experiments are carried out synchronously on the papers laminated by the paper bag film laminating machine of the present invention and the commercially available paper bag film laminating machine. Since the commercially available paper bag film laminating machine requires manual wiping of the paper with a pure cotton dry towel, 5 additional staff members are added to each commercially available paper bag film laminating machine to wipe the papers to be laminated, and the number of papers laminated by the two paper bag film laminating machines after 1 hour, 2 hours and 3 hours is measured and recorded:

[0063]

[0064] As can be seen from the above experimental data, with the increase of the usage time, the film laminating efficiency of the paper bag film laminating machine of the present invention is higher than that of the commercially available paper bag film laminating machine. Since the commercially available paper bag film laminating machine requires manual wiping of the paper; with the increase of the usage time, the physical strength of the staff decreases, resulting in a lower and lower speed of the staff wiping the paper, thus making the production efficiency of the commercially available paper bag film laminating machine lower and lower. And by comparing and observing the papers laminated by the paper bag film laminating machine of the present invention and the papers laminated by the commercially available paper bag film laminating machine, and by checking the film laminating quality, it is found that the quality of the papers laminated by the commercially available paper bag film laminating machine becomes worse and worse with the increase of the usage time. After analysis, it can be seen that due to the long-term work, the physical strength of the staff decreases, resulting in a worse and worse cleanliness of the paper after wiping, which further confirms the application effect of the paper bag film laminating machine of the present invention.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.

A hand-held paper bag production process, which is applicable to the hand-held paper bag production device described in any one of claims 1-2, characterized in that: The steps of this process are as follows: S1: First, print the paper for making the hand-held paper bag through a printing machine, then evenly spray plant starch on the printed surface of the printed paper, stack and stand still to make the printed surface dry. When it is necessary to laminate the printed paper, the staff places the stacked paper on the feeding mechanism, and cleans the paper on the top layer of the stack. The feeding mechanism sends the paper to the dust removal mechanism; S2: When the top layer of paper is sent to the previous dust removal plate (21), the previous electric push rod (22) pushes the previous dust removal plate (21) to contact the paper. When the surface of the previous dust removal plate (21) is about to be covered with dust, the latter electric push rod (22) pushes the latter dust removal plate (21) to contact the printed surface of the paper. At this time, the previous electric push rod (22) pulls the previous dust removal plate (21) to rise, and the driving motor (24) pulls the U-shaped scraper (23) through the steel wire rope (25) to scrape off the dust on the surface of the dust removal plate (21); S3: After the current dust removal plate (21) is cleaned, control the electromagnet (26) to be energized, so that the electromagnet (26) adsorbs the scraper (23), so that the scraper (23) is reset under the suction of the electromagnet (26).

At this time, the latter dust removal plate (21) rises and is cleaned, and so on until all the papers are laminated; S4: After lamination, the staff finishes the surface of the laminated paper, then performs die-cutting processing on the finished paper, then pastes the die-cut paper into a bag, and finally punches and threads the pasted paper bag to obtain the required hand-held paper bag.

8. A hand-held paper bag production process, which is applicable to the hand-held paper bag production device described in claim 6, characterized in that: The steps of this process are as follows: S1: First, print the paper for making the hand-held paper bag through a printing machine, then evenly spray plant starch on the printed surface of the printed paper, stack and stand still to make the printed surface dry. When it is necessary to laminate the printed paper, the staff places the stacked paper on the feeding mechanism, and cleans the paper on the top layer of the stack. The feeding mechanism sends the paper to the dust removal mechanism; S2: Before laminating the printed paper, first rotate the mounting rod (34) to adjust the scraping angle of the scraping blade (33) against the dust removal belt (31). When the printed surface of the topmost paper makes sliding contact with the lower end surface of the dust removal belt (31), start the servo motor (32) so that the servo motor (32) drives the dust removal belt (31) to rotate through the rotating shaft (3). As the feeding mechanism continuously conveys the paper, the dust will be blocked on one side of the dust removal belt (31) and continuously accumulate in the dust storage groove (311). The rotation of the dust belt causes the dust removal belt (31) to drive the dust in the dust storage groove (311) to fall from the upper end of the machine body (1); S3: The part of the dust removal belt (31) that crosses the machine body (1) contacts the scraping blade (33), so that the scraping blade (33) scrapes the dust on the blocking surface of the dust removal belt (31) and in the dust storage groove (311), so that the dust adhering to the blocking surface of the dust removal belt (31) and at the dust storage groove (311) is separated from the blocking belt under the scraping of the scraping blade (33). At this time, the paper after dust removal is conveyed by the feeding mechanism to the laminating mechanism for laminating; S4: After laminating, the staff finishes the surface of the laminated paper, then performs die-cutting on the finished paper, then pastes the die-cut paper into bags, and finally punches and threads the pasted paper bags to obtain the required hand-held paper bags.
