Description

Technical Field

[0001] The invention relates to the technical field of printed matter bonding, in particular to a bonding device for printed matter processing. Background Art

[0002] The bonding device for printed matter processing is a device specially used for post-processing of printed matter. Its main function is to bond printed paper, cardboard and other materials with adhesive to realize processes such as book binding and paper box forming. The device is mainly composed of a glue supply system, a glue coating device, a pressing mechanism, a conveying device and a control system. The glue supply system is responsible for providing an appropriate amount of adhesive, and the glue coating device evenly applies the adhesive to the specified position of the printed matter. The pressing mechanism applies appropriate pressure to make the bonding parts fit tightly to ensure a firm bond. The conveying device is responsible for smoothly feeding the printed matter into the bonding device to complete the bonding process. The control system accurately regulates the entire bonding process to ensure product quality.

[0003] Traditional adhesive devices for printing processing are widely used in the printing industry, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, the gluing method is single. These devices can only use a certain gluing method, lacking flexibility and diversity, and it is difficult to meet the different requirements for gluing methods in different printing processing processes. This singleness limits the application of adhesive devices in complex processes and affects the quality and aesthetics of the products. Another problem is the inconvenience of adjusting the gluing width and thickness. In traditional adhesive devices, the adjustment of the gluing width and thickness usually needs to be achieved by replacing the gluing roller. Such an operation process is cumbersome. When it is necessary to frequently change product specifications or carry out small batch production, this adjustment method is not only time-consuming and labor-intensive, but also easy to cause material waste and increase production line downtime. In addition, due to the inconvenience of adjustment, it is difficult for operators to quickly and accurately adjust the gluing parameters according to the material and bonding requirements of different printed products, resulting in unstable bonding effects. Sometimes there will be problems such as weak bonding or excessive glue. These problems not only affect production efficiency, but also increase the operating costs of enterprises.

[0019] 2. Through the setting of the glue spraying mechanism, flexible conversion of the glue coating method is realized, so that the device can switch from the traditional rolling glue mode to the glue spraying mode, which improves the applicability of glue coating and can evenly spray adhesive according to the surface conditions of different printed products. This switching ability enables the bonding device to better adapt to thin paper, special materials or printed products with complex patterns, reducing paper damage and adhesive waste during the gluing process. Through the setting of the glue spraying mechanism, the gluing method of the bonding device is more diversified, meeting the market's diversified needs for post-processing of printed products.

[0020] 3. The closed unit is set up so that the nozzle can automatically remain closed when the air source is not connected, avoiding the problem of glue leakage and eliminating the tedious steps of manually operating the nozzle. When the air source is disconnected, the valve automatically closes to form a sealed environment to prevent the glue from flowing out due to gravity or external pressure. This not only reduces the waste of glue, but also keeps the working environment clean. In addition, the design of the closed unit also reduces the risk of accidental injury to operators due to contact with glue, as well as the time cost during operation. Through this automatic closing mechanism, the operation of the bonding device becomes safer and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a bonding device for printed matter processing, including a machine table 1, a bracket 2 fixedly connected to the top of the machine table 1, a conveyor belt 3 rotatably connected to the bottom of the bracket 2, a hopper 4 fixedly connected to the top of the bracket 2, and also includes a glue rolling mechanism 5 fixedly connected to the bottom of the hopper 4, and a glue spraying mechanism 6 fixedly connected to the bottom of the hopper 4; the glue rolling mechanism 5 includes a transverse movement unit and a width adjustment unit fixedly connected to the bottom of the transverse movement unit; the transverse movement unit includes a material roller 51 rotatably connected to the middle of the bracket 2, a corrugated sleeve 52 fixedly connected to the bottom of the hopper 4, and a material nozzle 53 fixedly connected to the bottom of the corrugated sleeve 52, two A guide rail 54 is symmetrically fixedly connected to both sides of the nozzle 53, a fixed frame 55 is fixedly connected to the bottom of the hopper 4, two slide grooves 56 are symmetrically opened on both sides of the fixed frame 55, the inner wall of the slide groove 56 is slidably connected to the outer wall of the guide rail 54, a screw hole 57 is opened at the bottom of the fixed frame 55, an adjusting rod 58 is meshed and connected to the inside of the screw hole 57, the middle part of the knob 519 is meshed and connected to the inner wall of the screw hole 57, a limit block 59 is fixedly connected to the side of the nozzle 53 close to the fixed frame 55, a stepped hole 510 is opened on the side of the limit block 59 close to the fixed frame 55, and the end of the adjusting rod 58 close to the nozzle 53 is rotatably connected to the stepped hole 510.

[0039] Specifically, the limit block 59 is driven to move by rotating the adjustment rod 58, and the movement of the limit block 59 drives the material nozzle 53 to move at the same time. By rotating the adjustment rod 58 in different directions, the material nozzle 53 can be driven to move in different directions. When the material nozzle 53 moves toward the direction close to the material roller 51, the glue applied on the material roller 51 will become thinner, and when the material nozzle 53 is away from the material roller 51, the glue attached to the material roller 51 will become thicker. The setting of the glue rolling mechanism 5 provides greater flexibility for printed product processing, allowing the operator to adjust the width and thickness of the glue coating according to different production requirements. This adjustment function enables the bonding device to adapt to printed products of various specifications and ensure the consistency and stability of the bonding effect. Through simple operation, the glue rolling mechanism 5 can realize glue control and avoid waste of glue. At the same time, it also improves the appearance quality of the product, so that the bonding device can cope with diverse production tasks and improve production efficiency.

[0040] Reference Figure 8-Figure 10 A thread is provided in the middle of the adjusting rod 58, and the shape of the adjusting rod 58 at one end close to the nozzle 53 matches the stepped hole 510, and the cross section of the corrugated sleeve 52 is wavy.

[0041] Specifically, the adjusting rod 58 will move along its own axis under the action of the thread while rotating, and the end of the adjusting rod 58 close to the nozzle 53 can rotate inside the stepped hole 510 , and the corrugated sleeve 52 can be deformed as the nozzle 53 moves.

[0042] Reference Figure 3-Figure 9 The width adjustment unit includes a orifice plate 511 fixedly connected to the bottom of the nozzle 53, a long hole 1 512 opened at the top of the orifice plate 511, a guide hole 513 opened at the bottom of the material port, an arc plate 514 slidably connected to the inside of the guide groove, a long hole 2 515 opened at the top of the arc plate 514, the top of the arc plate 514 is slidably connected to the bottom of the orifice plate 511, a rack 516 fixedly connected to the side of the arc plate 514 away from the long hole 2 515, a support shaft 517 fixedly connected to the side of the nozzle 53 close to the rack 516, a gear 518 rotatably connected to the outside of the support shaft 517, and a knob 519 fixedly connected to the gear 518 away from the side of the nozzle 53.

[0043] Specifically, by rotating the gear 518, the rack 516 can be driven to move, the rack 516 drives the arc plate 514 to move, and the long hole 2 515 moves together with the arc plate 514. The overlapping part of the long hole 1 512 and the long hole 2 515 can allow the glue to flow through. By controlling the relative positions of the long hole 1 512 and the long hole 2 515, the width of the glue output can be adjusted.

[0044] Example 2, reference Figure 5-Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the top of the arc plate 514 and the bottom of the orifice plate 511 have the same curvature, and the long hole 1 512 and the long hole 2 515 have the same size and shape.

[0045] Specifically, the arc plate 514 is constrained by the guide hole 513 and thus remains in contact with the bottom plate while moving.

[0046] Reference Fig.11 and Fig.15 The glue spraying mechanism 6 includes a glue supply unit, a closing unit fixedly connected to the inside of the glue supply unit, and a ventilation unit fixedly connected to the top of the glue supply unit; the glue supply unit includes two through holes 61 symmetrically opened at the bottom of the hopper 4, a cross bar 62 rotatably connected to the bottom of the hopper 4, the two ends of the cross bar 62 are rotatably connected to the two through holes 61, a flow channel 63 opened on the inner side of the through hole 61, a plurality of linear arrays fixedly connected to the elbow 64 on the side of the cross bar 62 away from the hopper 4, a ratchet 65 fixedly connected to the side of the cross bar 62 close to the gear 518, a claw 66 abutting against the side of the material port close to the ratchet 65, a positioning shaft 67 rotatably connected to the middle of the claw 66, and a torsion spring 68 fixedly connected to the outside of the positioning shaft 67, and the two ends of the torsion spring 68 are respectively fixedly connected to the positioning shaft 67 and the claw 66.

[0047] Specifically, the glue liquid in the hopper 4 enters the flow channel 63 through the through hole 61, and then enters the bend 64, and enters the inside of the nozzle 69 through the bend 64. The setting of the glue spraying mechanism 6 realizes the flexible conversion of the glue coating method, so that the device can switch from the traditional rolling glue mode to the glue spraying mode, which improves the applicability of glue coating and can evenly spray adhesive according to the surface conditions of different printed products. This switching capability enables the bonding device to better adapt to thin paper, special materials or printed products with complex patterns, reducing paper damage and adhesive waste during the gluing process. Through the setting of the glue spraying mechanism 6, the gluing method of the bonding device is more diversified, meeting the market's diversified needs for post-processing of printed products.

[0048] Reference Fig.13 The closed unit includes a nozzle 69 fixedly connected to the bottom of the curved pipe 64, a reducing hole 610 opened at the top of the nozzle 69, a lifting block 611 slidably connected to the inside of the reducing hole 610, a ring plate 612 fixedly connected to the middle of the lifting block 611, a spring 613 fixedly connected to the top of the ring plate 612, the bottom and top of the spring 613 are respectively fixedly connected to the inner wall of the ring plate 612 and the reducing hole 610, a special-shaped hole 614 opened at the top of the lifting block 611, and a round rod 615 fixedly connected to the bottom of the lifting block 611.

[0049] Specifically, the spring 613 presses the ring plate 612 downward, and the ring plate 612 drives the lifting block 611 to move together. When the lifting block 611 moves downward, it drives the round rod 615 to move, so that the round rod 615 blocks the bottom of the variable diameter hole 610. The closing unit can make the nozzle 69 automatically maintain a closed state when the air source is not connected, thereby avoiding the problem of glue leakage and eliminating the tedious steps of manually operating the nozzle 69. When the air source is disconnected, the valve automatically closes to form a sealed environment to prevent the glue from flowing out due to gravity or external pressure. This not only reduces the waste of glue, but also keeps the working environment clean. In addition, the design of the closing unit also reduces the risk of accidental injury that may occur to the operator due to contact with the glue, as well as the time cost during operation. Through this automatic closing mechanism, the operation of the bonding device becomes safer and more efficient.

[0050] Reference Figure 1-Figure 9 The ventilation unit includes an air pipe 616 fixedly connected to the top of the cross bar 62, an air chamber 617 opened inside the nozzle 69, a top plate 618 slidably connected to the top of the air chamber 617, two short rods 619 symmetrically fixedly connected to the top of the top plate 618, and the top of the short rod 619 is fixedly connected to the ring plate 612.

[0051] Specifically, the top of the air pipe 616 is connected to the air source, and the high-pressure gas enters the air chamber 617 through the air pipe 616, so that the air pressure in the air chamber 617 increases, thereby moving the top plate 618 upward, and the top plate 618 pushes the ring plate 612 upward through the short rod 619. After the ring plate 612 moves up, the spring 613 is compressed and drives the lifting block 611 to rise. After the lifting block 611 moves up, it drives the round rod 615 upward, thereby releasing the blockage of the reducing hole 610 by the round rod 615.

[0052] Reference Figure 1-Figure 10 The inner diameter and outer diameter of the ring plate 612 are the same as those of the top plate 618, and the top plate 618 of the air chamber 617 has two symmetrical straight holes.

[0053] Specifically, the straight hole passes through the variable diameter hole 610 and the air chamber 617, and can accommodate the short rod 619 to move inside. The rest of the structure is the same as that of the first embodiment.

[0054] In summary, the working principle of the present invention is as follows: put the glue into the hopper 4, and then turn the knob 519 to drive the gear 518 to rotate. The gear 518 rotates and drives the arc plate 514 to move. The arc plate 514 is constrained by the guide hole 513, so it will move along the guide hole 513. The arc plate 514 is controlled to drive the long hole 2 515 to move, so that the long hole 2 515 overlaps with the long hole 1 512. The more the long hole 1 512 overlaps with the long hole 2 515, the greater the width of the glue that can be discharged. After the glue passes through the long hole 1 512 and the long hole 2 515 in turn, it falls onto the surface of the material roller 51. After the material roller 51 rotates, its outer edge will be coated with glue, so that the glue is scraped onto the surface of the material roller 51 through the nozzle 53, and the printed matter passes through. The gap between the conveyor belt 3 and the material roller 51, the material roller 51 will contact the upper surface of the printed matter, so that the glue liquid is rolled on the upper surface of the printed matter. When the glue coating thickness needs to be increased, the adjusting rod 58 is rotated to move it in the direction away from the hopper 4. The adjusting rod 58 drives the material nozzle 53 to move in the same direction through the limit block 59. After the distance between the material nozzle 53 and the material roller 51 increases, the thickness of the glue liquid that can be scraped onto the material roller 51 will also increase. By moving the arc plate 514, the long hole 1 512 and the long hole 2 515 are completely misaligned, so that the material port can be blocked to prevent the glue liquid from falling. When it is necessary to spray glue, the hook claw 66 is pressed down away from one end of the cross bar 62, and the hook claw 66 will rotate around the positioning shaft 67 as the center to store force in the torsion spring 68. After the hook claw 66 rotates, it will release The meshing with the ratchet 65 enables the ratchet 65 and the cross bar 62 to rotate freely. The rotating cross bar 62 drives the elbow 64 and the nozzle 69 to rotate together, and the nozzle 69 is adjusted to the position aligned with the conveyor belt 3. Then, the downward pressure on the hook 66 is released. The hook 66 will be reset and meshed with the ratchet 65 under the action of the torsion spring 68, so that the ratchet 65 and the cross bar 62 can no longer rotate downward. After the glue liquid is put into the hopper 4, the glue liquid enters the flow channel 63 inside the cross bar 62, and enters the elbow 64 through the flow channel 63, and then enters the reducing hole 610 inside the nozzle 69 through the elbow 64, and then the glue liquid enters the bottom of the reducing hole 610 through the special-shaped hole 614. After the air source connected to the air pipe 616 is connected, the high-pressure airflow enters the air chamber 617 through the air pipe 616, and is discharged from the air chamber The bottom of 617 is sprayed out, and the air pressure in the air chamber 617 will rise during this process, pushing the top plate 618 to move up, and the top plate 618 drives the short rod 619 to move up. When the short rod 619 moves up, it drives the ring plate 612 to move up. When the ring plate 612 moves, it squeezes the spring 613 and drives the lifting block 611 to move up together. The lifting block 611 drives the round rod 615 to move up. After the round rod 615 moves up, the blockage on the bottom of the variable diameter hole 610 is released, so that the glue can flow out from the bottom of the variable diameter hole 610. After the glue flows out, it is impacted and broken by the high-pressure gas at the bottom of the air chamber 617 to form a spray, which is sprayed onto the surface of the printed matter on the transmission belt. When the air source is turned off, the pressure in the air chamber 617 is balanced with the outside world, and the spring 613 will push the round rod 615 to reset through the lifting block 611.The round rod 615 blocks the bottom of the variable diameter hole 610 again to prevent the glue from flowing out.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
