Description

Technical Field

[0001] This invention relates to the field of corrugated board production technology, specifically to a gluing device for corrugated board production. Background Technology

[0002] Corrugated cardboard is a sheet-like material made by bonding face paper and corrugated paper formed by corrugating rollers. It is generally divided into single-wall corrugated cardboard and double-wall corrugated cardboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability and convenient storage and handling. In the process of corrugated cardboard processing, a corrugated cardboard gluing device is used to apply glue to the two crests of the corrugated core paper so as to bond the corrugated paper and face paper together to form a complete corrugated cardboard.

[0003] In existing technology, corrugated cardboard production typically involves using two forming rollers to press the cardboard into a corrugated shape. A glue roller is located on one side of the forming rollers, and glue is applied to one side of the corrugated paper before lamination. However, during production, different shapes of corrugated core paper are usually required. Since the shape of the forming rollers cannot be changed, they need to be replaced, which is a cumbersome and time-consuming process that affects production progress. Furthermore, when applying glue to the other side of the corrugated core paper, it needs to be glued again, increasing the production process and affecting production efficiency.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0019] Please refer to Figures 1-9As shown, a gluing device for corrugated cardboard production includes a machine body 1. A conveyor 101 is arranged on the top left side of the machine body 1. A first forming roller 102, a second forming roller 103, and a first guide roller 104 are arranged on the top of the conveyor 101. The first forming roller 102 and the second forming roller 103 cooperate to form the corrugated core paper 109. A first upright plate 105 and a second upright plate 107 are also fixedly installed on the top right side of the machine body 1. Two sets of second guide rollers 106 and two sets of third guide rollers 108 are respectively arranged on the front side of the first upright plate 105 and the second upright plate 107. The two sets of second guide rollers 106 and the two sets of third guide rollers 108 are respectively used to transport the top paper 110 and the bottom paper 111. A bonding mechanism 2 is installed on the top rear side of the machine body 1. A gluing mechanism 3 is arranged on the bonding mechanism 2. A drive mechanism 4 and two sets of switching mechanisms 5 are also installed on the top front side of the machine body 1. Example 2

[0020] Please refer to Figure 3 As shown, the bonding mechanism 2 includes a fixed frame 201, a first lead screw 202, and a first guide rod 203. The fixed frame 201 is provided with two sets of components, both of which are fixedly installed on the rear side of the top of the machine body 1. The first lead screw 202 is rotatably connected inside the fixed frame 201, and the first guide rod 203 is fixedly connected inside the fixed frame 201. The top of the first lead screw 202 extends above the fixed frame 201 and is fixedly installed with a first bevel gear 204.

[0021] Please refer to Figure 3 As shown, the bonding mechanism 2 also includes a lifting plate 207, which is threadedly connected to the outer wall of the first lead screw 202 and slidably connected to the outer wall of the first guide rod 203. A fourth guide roller 208 is rotatably connected to the outer side of the lifting plate 207. A dual-axis motor 205 is also provided on the top of the fixed frame 201. A second bevel gear 206 is fixedly connected to both output ends of the dual-axis motor 205. The second bevel gear 206 meshes with the first bevel gear 204.

[0022] Those skilled in the art will understand that the output of the dual-axis motor 205 drives the second bevel gear 206 to rotate, causing the first bevel gear 204 and the first lead screw 202 to rotate as a whole, which in turn drives the lifting plate 207 to move up and down along the outer wall of the first guide rod 203, thereby driving the fourth guide roller 208 to move up and down. The fourth guide roller 208 on the right is used to transport the top paper 110, and the fourth guide roller 208 on the left is used to transport the bottom paper 111. The dual-axis motor 205 has two outputs that can be controlled separately, thereby enabling the top paper 110 or the bottom paper 111 to be bonded to the corrugated core paper 109 separately. Example 3

[0023] Please refer to Figure 4 and Figure 5As shown, the glue application mechanism 3 includes a rotating gear ring 301 rotatably connected to the outside of the fourth guide roller 208. A drive motor 302 is also provided on the outside of the fourth guide roller 208. A drive gear 303 is fixedly installed at the output end of the drive motor 302. The drive gear 303 meshes with the rotating gear ring 301. A connecting frame 304 is fixedly connected to the outside of the rotating gear ring 301.

[0024] Please refer to Figure 4 and Figure 5 As shown, a second lead screw 305 is rotatably connected inside the connecting frame 304. The outer end of the second lead screw 305 is fixedly connected to the output end of the first stepper motor 307. The first stepper motor 307 is set on the outer wall of the connecting frame 304. A moving plate 308 is threadedly connected to the outer surface of the second lead screw 305. A multi-functional roller 309 is threadedly connected to the outer wall of the moving plate 308. The moving plate 308 is slidably connected to the second guide rod 306. The second guide rod 306 is fixedly connected inside the connecting frame 304. The multi-functional roller 309 is hollow inside and has uniform through holes. The multi-functional roller 309 is connected to the external air pump and glue applicator.

[0025] Those skilled in the art will understand that by controlling the output end of the first stepper motor 307 to rotate, the second lead screw 305 rotates, causing the moving plate 308 to reciprocate along the outer wall of the second guide rod 306, thereby enabling the multifunctional roller 309 to move closer to or away from the fourth guide roller 208; and by driving the output end of the drive motor 302 to rotate, the rotating gear ring 301 rotates, thereby enabling the multifunctional roller 309 to rotate around the center of the rotating gear ring 301 as the "center". Example 4

[0026] Please refer to Figure 6 As shown, the drive mechanism 4 includes a support plate 401, a third lead screw 404, and a lifting block 407. The support plate 401 is welded to the top front side of the body 1. The support plate 401 has a first mounting groove 402 and a second mounting groove 403 on both sides. The third lead screw 404 is rotatably connected to the inside of the first mounting groove 402. The lifting block 407 is threadedly connected to the outer wall of the third lead screw 404. A third guide rod 405 is also fixedly installed inside the first mounting groove 402. The lifting block 407 is slidably connected to the outer wall of the third guide rod 405.

[0027] Please refer to Figure 6 As shown, a second stepper motor 406 is fixedly connected to the top of the support plate 401. The output end of the second stepper motor 406 extends into the interior of the first mounting groove 402 and is fixedly connected to the outer end of the third lead screw 404. A first pressing plate 408 and a drive rod 409 are fixedly installed on the outer side of the lifting block 407.

[0028] Please refer to Figure 7 As shown, a fixing rod 410 is fixedly connected inside the second mounting groove 403, and a lifting frame 412 is slidably connected to the outer wall of the fixing rod 410. A first spring 411 is fixedly installed on the top of the lifting frame 412, and the other end of the first spring 411 is fixedly installed on the inner top wall of the second mounting groove 403. The inner wall of the lifting frame 412 is fixedly connected to the first inclined block 414 through the second spring 413. A first sliding rod 415 is fixedly connected to the outer side of the first inclined block 414. The first sliding rod 415 is slidably connected to the lifting frame 412, and a second pressing plate 416 is fixedly installed on the outer side of the lifting frame 412. A second inclined block 417 is also provided on the outer top of the support plate 401.

[0029] Those skilled in the art will understand that the output of the second stepper motor 406 drives the third lead screw 404 to rotate, causing the lifting block 407 to move upward along the outer wall of the third guide rod 405, which in turn drives the drive rod 409 to move upward. The drive rod 409 supports the bottom of the first inclined block 414 and moves upward, causing the first spring 411 to be in a contracted state. When the inclined surface of the first inclined block 414 contacts the inclined surface of the second inclined block 417, the first inclined block 414 is driven to retract into the interior of the lifting frame 412, causing the second spring 413 to be in a contracted state. The drive rod 409 then no longer contacts the bottom of the first inclined block 414. Under the action of the first spring 411 restoring its deformation, the lifting frame 412 and the second pressing plate 416 are driven to move upward as a whole. When the second pressing plate 416 moves downward, it can press the switch mechanism 5 on its bottom side. Next, the output end of the second stepper motor 406 is driven to rotate in the opposite direction, so that the lifting block 407 begins to move downward along the outer wall of the third guide rod 405, driving the drive rod 409 to move downward as well. When the drive rod 409 contacts the inclined surface of the first inclined block 414, it can also drive the first inclined block 414 to retract into the interior of the lifting frame 412. In this way, the lifting block 407 can bypass the first inclined block 414 and return to below the first inclined block 414. When the lifting block 407 is below the first inclined block 414 and continues to move downward, it drives the first pressing plate 408 to move downward, and also presses the set of switch mechanisms 5 on its bottom side. Example 5

[0030] Please refer to Figure 8 and Figure 9As shown, the switch mechanism 5 includes a frame 501 fixedly installed on the top of the body 1. A third spring 502 is fixedly installed at the bottom of the inner part of the frame 501. The other end of the third spring 502 is connected to the switch 503. A false heart-shaped groove 504 is provided on the front side of the switch 503. A second sliding rod 507 is fixedly connected to the top of the switch 503. The second sliding rod 507 is slidably connected to the frame 501. A rotating part 505 is rotatably connected to the bottom front side of the frame 501. A sliding part 506 is provided at the other end of the rotating part 505. The sliding part 506 is slidably connected to the false heart-shaped groove 504. The two sets of second sliding rods 507 are located directly below the first pressing plate 408 and the second pressing plate 416, respectively. The two sets of switch mechanisms 5 are used to control the external air pump and the glue applicator, respectively.

[0031] Those skilled in the art will understand that, through the above description of the drive mechanism 4, the switch mechanism 5 can be pressed, that is, the second sliding rod 507 can be pressed, causing the switch 503 to move downward, the third spring 502 to be in a contracted state, the rotating part 505 to rotate, and the sliding part 506 to rotate clockwise in the false heart-shaped groove 504. The sliding part 506 moves from the bottom of the false heart-shaped groove 504 to the middle position of the top of the false heart-shaped groove 504 and stops there, thereby pressing down the switch 503 and fixing it at that height, and connecting the external air pump or glue applicator to start working; Subsequently, if the second sliding rod 516 is pressed again by the drive mechanism 4, the third spring 502 will restore its deformation, causing the sliding member 506 to rotate clockwise from the middle position of the top of the false heart-shaped groove 504 and move to the reset state. The switch 503 will then move upward to disconnect the circuit of the external air pump or glue applicator, and stop it from working.

[0032] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. Initially, the output end of the drive motor 302 is rotated, causing the rotating gear ring 301 to rotate, thereby driving the multi-functional roller 309 to rotate around the center of the rotating gear ring 301, so that the multi-functional roller 309 is directly above the fourth guide roller 208. Then, the output end of the first step motor 307 is controlled to rotate, causing the second lead screw 305 to rotate, driving the moving plate 308 to reciprocate along the outer wall of the second guide rod 306, thereby driving the multi-functional roller 309 to move closer to or away from the fourth guide roller 208, so that the distance between the two sets of multi-functional rollers 309 and the fourth guide roller 208 is exactly matched with the thickness of the top paper 110 and the bottom paper 111 to be conveyed. S2. Under the combined action of the first forming roller 102 and the second forming roller 103, the paper roll forms a corrugated core paper 109 with a wavy pattern, and pulls it to the platform located on the right side of the top of the machine body 1. The upper paper 110 is conveyed by the action of two sets of second guide rollers 106 and reaches the distance between the right multi-functional roller 309 and the fourth guide roller 208, while the lower paper 111 is conveyed by the action of two sets of third guide rollers 108 and reaches the distance between the left multi-functional roller 309 and the fourth guide roller 208. S3. At this time, the lifting block 407 is located below the first inclined block 414. The output end of the second stepper motor 406 drives the third lead screw 404 to rotate, causing the lifting block 407 to move downward along the outer wall of the third guide rod 405. This causes the first pressing plate 408 to move downward, pressing the switch mechanism 5 at its bottom for the first time. This connects the multi-functional roller 309 to the external air pump, allowing the multi-functional roller 309 to adsorb the upper paper 110 and the lower paper 111. Furthermore, under the action of the output end of the drive motor 302... This causes the multi-functional roller 309 to rotate around the center of the rotating gear ring 301. The multi-functional roller 309 pulls the adsorbed upper paper 110 and lower paper 111 to a position directly below the fourth guide roller 208. The bottom of the fourth guide roller 208 is also a vacuum suction plate, which also adsorbs the upper paper 110 and lower paper 111 pulled to this position. After that, the lifting block 407 moves upward a certain distance and then presses the switch mechanism 5 at its bottom a second time to disconnect the multi-functional roller 309 from the external air pump. S4. Conversely, the output of the second stepper motor 406 rotates in the opposite direction, causing the lifting block 407 to move upward along the outer wall of the third guide rod 405, driving the drive rod 409 to move upward as well. The drive rod 409 supports the bottom of the first inclined block 414 and moves upward, causing the first spring 411 to be in a contracted state. When the inclined surface of the first inclined block 414 contacts the inclined surface of the second inclined block 417, the first inclined block 414 is driven to retract into the interior of the lifting frame 412, causing the second spring 413 to be in a contracted state. The drive rod 409 no longer contacts the bottom of the first inclined block 414. Under the action of the first spring 411 restoring its deformation, the lifting frame 412 and the second pressing plate 416 move downward as a whole. When the second pressing plate 416 moves downward, the switch mechanism 5 on its bottom side can be pressed, connecting the multi-functional roller 309 to the external glue applicator. The output of the drive motor 302 is then connected. The rotation causes the rotating gear ring 301 to rotate, thereby driving the multi-functional roller 309 to rotate around the center of the rotating gear ring 301. The multi-functional roller 309 applies glue to the surfaces of the adsorbed upper paper 110 and lower paper 111. When the glue application is about to be completed, the output end of the second stepper motor 406 is immediately driven to rotate in the opposite direction, causing the lifting block 407 to start moving downward along the outer wall of the third guide rod 405, driving the drive rod 409 to move downward as well. When the drive rod 409 contacts the inclined surface of the first inclined block 414, it can also drive the first inclined block 414 to retract into the interior of the lifting frame 412. In this way, the lifting block 407 can bypass the first inclined block 414 and return to the bottom of the first inclined block 414. Repeat the above steps, and quickly press the switch mechanism 5 on its bottom side a second time to quickly disconnect the external glue applicator from the multi-functional roller 309. S5. After the glue is applied, the output end of the dual-axis motor 205 drives the second bevel gear 206 to rotate, causing the first bevel gear 204 and the first lead screw 202 to rotate as a whole. This causes the top paper 110, which is held in place, to move downward and contact the top of the corrugated core paper 109 on the platform. It also causes the bottom paper 111, which is held in place, to move upward and contact the bottom of the corrugated core paper 109. This automates the connection of the ends of the top paper 110 and the bottom paper 111 to the corrugated core paper 109. S6. Secondly, under the action of the output end of the drive motor 302, both sets of multi-functional rollers 309 are rotated to the bottom directly below the two sets of fourth guide rollers 208 respectively, and the second pressing plate 416 is driven to connect with the external glue applicator, so that both sets of multi-functional rollers 309 are bonded to the surface of the top paper 110 and the bottom paper 111 and glued. S7 controls the conveyor 101 to continue conveying the corrugated core paper 109, and also controls the two sets of second guide rollers 106 and two sets of third guide rollers 108 to continue conveying the top paper 110 and the bottom paper 111. This achieves automated continuous lamination of the top paper 110 and the bottom paper 111 with the corrugated core paper 109, thereby automating the production of corrugated board. The entire process is automated, convenient, fast, and improves production efficiency, meeting the needs of the staff.
