Description

Technical Field

[0001] The utility model relates to the technical field of printing processing, in particular to a local adhesive backing component for paper. Background Art

[0002] The gluing process is widely used in life and production, such as self-adhesive stickers, posters, adhesive tapes, and paper binding, etc., and the equipment used varies according to the gluing location, gluing format, and gluing amount. At present, in the printing industry, the gluing process on the market is mainly used in the production of finished products, and is rarely used in the printing process.

[0003] A Chinese patent with announcement number CN220825026U discloses a paper corner glue coating machine, which applies glue through a glue head and a colloid under a rotating drum. However, in current printing factories, during the production of multi-copy forms and multiple printed products, multiple sheets of paper printed at the same time are converged by paper feed rollers and then sent to a cutting position for cutting, which can easily cause slight displacement of the paper, misalignment of the same printed part of multiple layers of paper, uneven cutting, and defects in subsequent operations, thereby affecting the quality of printed products and causing production losses. Utility Model Content

[0004] In view of the above problems, the utility model provides a paper local adhesive backing component.

[0010] The first bearing is inserted into the glue box, and the first bearing can drive the glue application mechanism to rotate.

[0011] Optionally, the driving mechanism further includes a connecting platform and a motor mounting seat;

[0012] The connecting platform is connected to one side of the plastic box;

[0013] The motor mounting seat is arranged on the connecting platform, a motor is fixed on the motor mounting seat, and a power output end of the motor is connected to the center of the driving wheel.

[0014] Optionally, the driven wheel is arranged above the driving wheel, and the driven wheel is mounted on the part of the first bearing located outside the rubber box.

[0015] Optionally, the gluing mechanism includes a rubber rolling wheel, a gluing wheel and a second bearing;

[0016] The rubber rolling wheel is arranged in the rubber box and sleeved on the first bearing, and the circumference of the rubber rolling wheel is in contact with the circumference of the rubber upper wheel;

[0017] The second bearing is arranged on the top of the plastic box;

[0023] 2. Transferring glue from the rubber roller to the upper rubber wheel is helpful to control the amount of glue. At the same time, the rubber roller rotates continuously to prevent glue crusting, coagulation, and impurities, thereby improving the gluing quality of printed products and preventing the paper from being too hard and too thick after gluing, which is not conducive to cutting and thus affects the quality of printed products.

[0024] 3. It solves the problem that in the existing printing factories, during the production process of multi-copy forms and multiple printed products, multiple sheets of paper printed at the same time are mostly sent to the cutting part for cutting after being intersected by the paper feed roller, which easily causes the paper to shift slightly, and the same printing part of multiple layers of paper is misplaced and cut unevenly, and solves the problem of defects in subsequent operations, thus affecting the quality of printed products and causing production losses.

[0034] The purpose of such a design is to provide a local back-gluing component of the paper including a gluing mechanism and a driving mechanism, wherein the driving mechanism can drive the gluing mechanism to work, and at the same time, an O-shaped rubber ring is provided on the gluing mechanism so that the glue in contact with the paper forms a convex point contact, and is evenly coated on the gluing part through operation, so as to prevent the glue from flowing due to excessive thickness and affecting the quality of the printed matter. This solves the problem that in the existing printing factories, in the production process of multi-copy forms and multiple printed matters, most of the multiple sheets of paper printed at the same time are sent to the cutting part for cutting after being intersected by the paper feed roller, which easily causes the paper to shift slightly, the same printing part of multiple layers of paper is misaligned, and the cutting is uneven, and the defects in subsequent operations are solved, thereby affecting the quality of printed matters and causing production losses.

[0035] In this embodiment, Figure 3 and Figure 4 As shown, the driving mechanism includes a driven wheel 9 and a driving wheel 8;

[0036] The driving wheel 8 rotates driven by the motor;

[0037] The driven wheel 9 is arranged on the first bearing 11, and the driven wheel 9 is connected to the driving wheel 8, and the first bearing 11 is driven to rotate under the rotation of the driving wheel 8;

[0038] The first bearing 11 is inserted into the glue box 1, and the first bearing 11 can drive the glue application mechanism to rotate.

[0039] The driving mechanism also includes a connecting platform 6 and a motor mounting seat 7;

[0040] The connecting platform 6 is connected to one side of the plastic box 1;

[0041] The motor mounting seat 7 is arranged on the connecting platform 6 , a motor is fixed on the motor mounting seat 7 , and a power output end of the motor is connected to the center of the driving wheel 8 .

[0042] Meanwhile, the driven wheel 9 is arranged above the driving wheel 8 , and the driven wheel 9 is mounted on the portion of the first bearing 11 located outside the rubber box 1 .

[0043] Furthermore, the gluing mechanism includes a rubber rolling wheel 12, a gluing wheel 10 and a second bearing 13;

[0044] The rubber rolling wheel 12 is arranged in the rubber box 1 and is sleeved on the first bearing 11. The circumference of the rubber rolling wheel 12 is in contact with the circumference of the rubber-applying wheel 10.

[0045] The second bearing 13 is arranged on the top of the plastic box 1;

[0046] The rubberizing wheel 10 is sleeved on the second bearing 13 .

[0047] At the same time, a photoelectric sensor switch 5 is arranged on the side of the rubber box 1 , and the lower limit position of the photoelectric sensor switch 5 is higher than the lowest point of the curved surface of the rubber rolling wheel 12 .

[0048] In actual use, the glue injection port is located on the wall of one side of the glue box, the photoelectric sensor switch is located inside the glue box to monitor the upper and lower limits of the glue, the rubber roller is located inside the glue box, and an O-shaped rubber ring is installed on the wheel surface of the upper rubber wheel, which is fixed to the upper side of the inside of the glue box through the second bearing and frictionally fits with the rubber roller. The driving mechanism is located outside the glue box, and the driven wheel of the driving mechanism is located on the wall of one side of the glue box and is connected to the internal rubber roller through the first bearing.

[0050] The motor is engaged with the driving wheel, which is connected to the driven wheel gear. The motor drives the driving wheel to rotate, thereby driving the driven wheel to rotate. The bearing of the driven wheel drives the rubber roller to rotate, and the friction force drives the glue roller to rotate. The glue roller contacts the paper and glue is applied to the paper through the rotation of the glue roller.

[0051] In this way, the glue is transferred from the rubber roller to the upper rubber roller, which is conducive to controlling the amount of glue. At the same time, the rubber roller rotates continuously to prevent the glue from crusting, solidifying, and impurities, thereby improving the gluing quality of printed products and preventing the paper from being too hard and too thick after gluing, which is not conducive to cutting and thus affects the quality of printed products. The invention solves the problem that in the production process of multi-copy forms and multiple printed products in existing printing factories, most of the multiple sheets of paper printed at the same time are sent to the cutting part for cutting after the paper feed rollers are intersected, which easily causes the paper to shift slightly, the same printing part of multiple layers of paper is misaligned, and the cutting is uneven, and solves the problem of defects in subsequent operations, thereby affecting the quality of printed products and causing production losses.
