Description

Technical Field

[0001] The invention belongs to the technical field of paper tube processing, in particular to a paper tube forming machine. Background Art

[0002] Paper tube is a commonly used item in life. Paper tube has the advantages of being light, durable and environmentally friendly. The cylinder for badminton and the tube for wrapping cloth in textile production are all made of paper tube. During the forming process of paper tube, the paper roll will be formed by a paper tube forming machine, which includes the steps of unwinding, tensioning, gluing and rolling paper.

[0003] A patent application with the existing publication number CN112549657A discloses a paper tube processing equipment, including a base, a bracket fixed above the base, a tape unwinding mechanism arranged on one side of the top of the bracket, the paper in the tape unwinding mechanism is rotated and unrolled out by a first reduction motor, a counterweight mechanism is arranged in the center above the bracket, a tensioning mechanism is arranged on the bracket on one side of the counterweight mechanism, a driving paper feeding mechanism is arranged on the bracket below the tensioning mechanism, and a gluing mechanism, a cutting mechanism and a tube pressing and winding mechanism are arranged in front of the paper feeding mechanism.

[0004] During use of the above-mentioned technical solution, the paper needs to be laid out, tensioned, and coated with glue. During the gluing process, the glue is applied to the surface of the paper, and the glue may be unevenly applied, which will cause unstable bonding in some areas. The different thicknesses of the paper tapes will also cause changes in the thickness of the glue application, which will affect the bonding effect. The amount of glue applied may be large, which will cause the glue layer to be too thick. During the paper rolling process, glue overflows, which can easily cause the paper tube to adhere to the machine, making it inconvenient to remove the formed paper tube.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4As shown, a paper tube forming machine described in an embodiment of the present invention includes a workbench 1, a support plate 11 is installed on the top of the workbench 1, a reeling assembly 2 is installed on one side of the support plate 11, a tensioning assembly 3 is arranged on one side of the reeling assembly 2, the tensioning assembly 3 is installed on one side of the support plate 11, a paper roll assembly 5 is arranged below the reeling assembly 2, the paper roll assembly 5 is also installed on one side of the support plate 11, and a glue brushing structure is arranged below the tensioning assembly 3; the glue brushing structure includes a top plate 4 arranged below the tensioning assembly 3, one side of the top plate 4 is fixedly connected to the support plate 11, a pressure roller 41 is arranged on the side of the top plate 4 away from the tensioning assembly 3, a brush roller 42 is arranged below the pressure roller 41, and a brush roller 42 is arranged below the brush roller 42 There is a scraper plate 43, the outside of the pressure roller 41 is rotatably connected to a moving frame 411, the brush roller 42 is rotatably connected to the moving frame 411, the two sides of the scraper plate 43 are fixedly connected to the moving frame 411 through connecting plates, a slider 414 is fixed to the side of the moving frame 411 close to the support plate 11, a slide groove 412 is provided inside the support plate 11, the slider 414 is slidably connected to the inside of the slide groove 412, a first spring 415 is fixed to one side of the slider 414, the other side of the first spring 415 is fixedly connected to the inside of the slide groove 412, a guide rod is passed through the inside of the first spring 415, one end of the guide rod passes through the inside of the slider 414, and both ends of the guide rod are fixedly connected to the inner wall of the slide groove 412;

[0032] During the production of paper tubes, it is necessary to wind the paper roll into a paper tube. At this time, it is necessary to install the paper roll to be unwound on the unwinding component 2, then pull out the paper tape and pass the paper tape through the tensioning component 3, the glue brushing structure, and finally fix it on the reel surface of the paper winding component 5, then start the motor of the paper winding component 5 to drive the reel to rotate, and at this time the reel winds and winds the paper tape. In this process, the paper tape will be tensioned after passing through the unwinding component 2, which can make the paper tape in a taut state. Then the paper tape will pass through the surface of the top plate 4. At this time, the movable frame 411 drives the pressure roller 41 and the top plate 4 to be in a state of being separated. When the paper tape passes through the surface of the top plate 4, the movable frame 411 is released. At this time, the elastic force of the first spring 415 pushes the slider 414 to slide inside the slide groove 412. At this time, the movable frame 411 pushes the pressure roller 41 to be close to the direction of the top plate 4. At this time, the pressure roller 41 can push the paper tape to be attached to the surface of the top plate 4, and at the same time The thickness of the paper tape will limit the pressure roller 41. At this time, the pressure roller 41 drives the brush roller 42 to stick to the surface of the paper tape through the movable frame 411. At this time, the scraper plate 43 will automatically move with the movable frame 411. When the purpose of the processed paper tube is different, the thickness of the paper tape will also be different. When the thickness of the processed paper tape changes, the distance between the pressure roller 41 and the top plate 4 will be pushed by the paper tape to change. At this time, the distance between the pressure roller 41, the brush roller 42 and the scraper plate 43 and the paper tape can be automatically adjusted. Then the brush roller 42 rotates to apply glue to the paper tape passing through the surface of the top plate 4. After gluing, the paper tape passes through the scraper plate 43. At this time, there is a certain gap between the scraper plate 43 and the paper tape. The position with too much glue will be scraped off by the scraper plate 43. At this time, the glue on the surface of the paper tape can be in a more uniform state. Subsequently, the glue-coated paper tape is wound up by the paper roll assembly 5, and the paper tape can form a paper tube on the surface of the paper roll assembly 5.

[0033] like Figures 1 to 4 As shown, a first motor 413 is provided on the side of the slider 414 away from the pressure roller 41, and the first motor 413 is installed inside the support plate 11. A winding wheel is fixed to the end of the rotating shaft of the first motor 413, and a first pull rope 416 is wound around the outside of the winding wheel. The other end of the first pull rope 416 is fixedly connected to the slider 414;

[0034] In the initial state before work starts, the pressure roller 41 is in a position close to the top plate 4. When work needs to start, the first motor 413 is started to drive the winding wheel to reel in the first pull rope 416. At this time, the first pull rope 416 pulls the slider 414 to slide inside the slide groove 412. At this time, the slider 414 drives the movable frame 411 away from the top plate 4, and then keeps the movable frame 411 in the current position. When the paper tape is placed on the surface of the top plate 4, the first motor 413 is controlled to rotate in the opposite direction. At this time, the winding wheel of the first motor 413 unwinds the first pull rope 416. At this time, the elastic force of the first spring 415 pushes the slider 414, and the slider 414 drives the movable frame 411 to move, and at the same time pulls the first pull rope 416 to make it tight, and the movable frame 411 can be moved to adjust its position.

[0035] like Figures 3 to 5 As shown, a glue box 423 is fixed to the top of the workbench 1 near the top plate 4, a glue outlet plate 421 is provided on the side of the brush roller 42 away from the pressure roller 41, a plurality of glue outlet holes are opened inside the glue outlet plate 421, a plurality of glue delivery pipes 422 are fixed to the side of the glue outlet plate 421 near the glue box 423, a plurality of glue suction pipes are inserted inside the glue box 423, and the other ends of the plurality of glue delivery pipes 422 are respectively fixedly connected to the top ends of the plurality of glue suction pipes;

[0036] When in use, the glue box 423 stores the glue needed for brushing. During use, the glue inside the glue box 423 is output through the glue delivery pipe 422 and input into the glue outlet plate 421. The bottom of the glue suction pipe inside the glue box 423 is close to the bottom end of the inner wall of the glue box 423. At this time, the glue outlet hole of the glue outlet plate 421 outputs glue. When the brush roller 42 rotates, the brush head on the surface will contact the glue on the surface of the glue outlet plate 421, and the glue will adhere to the surface of the brush roller 42. Then the brush roller 42 smears the glue on the surface of the paper tape, thereby realizing the supply of glue.

[0037] like Figures 3 to 6 As shown, a second motor 44 is installed below the side of the movable frame 411 close to the slider 414, an output gear is fixed to the end of the rotating shaft of the second motor 44, a toothed plate is fixed to the end of the rotating shaft of the brush roller 42 close to one end of the second motor 44, the toothed plate is meshed with the output gear of the second motor 44, a rotating wheel 425 is fixed to the end of the rotating shaft of the brush roller 42 away from the toothed plate, a shell 426 is fixed to one side of the rotating wheel 425, the shell 426 is fixedly connected to the movable frame 411, a push rod 427 runs through the interior of the shell 426, a piston is fixed to the end of the push rod 427 close to the shell 426, a second spring 428 is fixed to the end of the piston away from the push rod 427, the other end of the second spring 428 is fixedly connected to the inner wall of the shell 426, the air inlet and the air outlet of the shell 426 are both provided with a one-way valve sheet, an air pipe 424 is fixed to the air outlet of the shell 426, and the bottom end of the air pipe 424 is connected to the rubber box 423;

[0038] When the brush roller 42 rotates, the second motor 44 is started to drive the toothed disc of the brush roller 42 to rotate through the output gear. At this time, the brush roller 42 is driven to rotate. During the rotation of the brush roller 42, the rotating wheel 425 is driven to rotate. Every time the rotating wheel 425 rotates 60°, it pushes the push rod 427. At this time, the push rod 427 pushes the piston to move inside the shell 426. At this time, the piston can input the air inside the shell 426 into the inside of the rubber box 423 through the air supply pipe 424. At this time, the rubber box As the amount of air inside 423 increases, the air pressure inside the glue box 423 will increase. At this time, the air pressure will press the glue in the glue box 423 downward, and the glue will be squeezed into the glue suction tube. The glue can be filled into the glue delivery tube 422 by rotating the brush roller 42 for several turns before brushing the glue, which is convenient for subsequent glue supply. During the glue brushing process, the brush roller 42 can brush the glue on the paper tape once every 60° rotation. At this time, the shell 426 will be driven to continuously input air into the glue box 423, so that automatic glue supply can be achieved according to the number of times the glue is brushed.

[0039] like Figure 7 As shown, a glue inlet 431 is fixed on one side of the scraper plate 43 away from the top plate 4, a guide tube 45 is fixed on the other side of the glue inlet 431, and a glue storage tank 432 is fixed on the bottom end of the guide tube 45;

[0040] After the brush roller 42 has brushed glue on the surface of the paper tape, there may be some uneven areas. At this time, the paper tape passes through the front end of the scraper plate 43, and the scraper plate 43 maintains a certain gap with the paper tape. When the thickness of the glue is greater than the size of the gap, it will contact the scraper plate 43, and the scraper plate 43 will scrape the glue off. The scraped glue will contact the subsequent paper tape, and can automatically fill the position where the subsequent paper tape has insufficient glue. Long-term scraping will result in more glue gathering inside the scraper plate 43, and the scraped glue enters the inside of the glue inlet 431. The glue inlet 431 will be stored in the glue storage tank 432 through the guide tube 45, so that the excess glue can be recovered and can be continued to be used in subsequent processing.

[0041] like Figures 3 to 7 As shown, a liquid spraying frame 433 is fixed to the bottom end of the scraper plate 43, and a plurality of water spraying heads are arranged on the top of the liquid spraying frame 433. A liquid storage tank 436 is fixed to the side of the glue box 423 away from the support plate 11, and a liquid pump 435 is installed on the top of the liquid storage tank 436. The water inlet end of the liquid pump 435 is connected to the liquid storage tank 436, and the water outlet end of the liquid pump 435 is fixed to a liquid infusion pipe 434, and the other end of the liquid infusion pipe 434 is connected to the liquid spraying frame 433.

[0042] After a long period of stopping gluing, a lot of glue may remain on the surface of the brush roller 42. After the glue solidifies, it will affect the subsequent use. Therefore, after each use, the first motor 413 drives the movable frame 411 away from the top plate 4, and then the brush roller 42 continues to rotate. At this time, the liquid pump 435 extracts the cleaning liquid mixed with the glue remover inside the liquid storage tank 436 and inputs it into the interior of the liquid spray frame 433 through the infusion tube 434. The liquid spray frame 433 sprays the cleaning liquid through the water spray head. The rotation of the brush roller 42 can clean the outside of the brush roller 42 to prevent the glue from solidifying on the surface of the brush roller 42. The glue inside the glue storage tank 432 can be taken out during the cleaning process.

[0043] like Figure 8 As shown, a drainage pipe 451 is fixed to one side of the flow guide pipe 45, a first flip plate 452 is rotatably connected to the interior of the drainage pipe 451, and a second flip plate 455 is rotatably connected to the bottom end of the interior of the flow guide pipe 45;

[0044] When the spray rack 433 cleans the brush roller 42, the cleaning liquid that falls down will be gathered by the scraper plate 43, and the gathered cleaning liquid will enter the interior of the guide tube 45. At this time, in order to prevent the cleaning liquid from entering the glue storage tank 432, the second flip plate 455 and the guide tube 45 are closed, and the first flip plate 452 and the drain pipe 451 are opened. At this time, the cleaning liquid will be discharged from the drain pipe 451 to the outside. At the same time, the drain pipe 451 can support the air pipe 424, so as to realize the extraction of the cleaning liquid.

[0045] like Figures 7 and 8 As shown, an elastic plate 453 is fixed to one end of the first flip plate 452 close to the second motor 44, a flip block 456 is fixed to one end of the second flip plate 455 close to the elastic plate 453, and limiting frames 457 are arranged on both sides of the flip block 456. The maximum rotation angle of the flip block 456 between the two limiting frames 457 is 90°. A transmission gear is fixed to one end of the first flip plate 452 away from the elastic plate 453, and a transmission gear is also fixed to one end of the second flip plate 455 away from the flip block 456. A lever 454 is arranged on one side of the elastic plate 453 away from the scraper plate 43, and the lever 454 is fixedly connected to the support plate 11.

[0046] When cleaning the brush roller 42, the movable frame 411 is away from the top plate 4. At this time, the movable frame 411 drives the guide tube 45 to move. During the movement, the elastic plate 453 contacts the lever 454. Under the limit of the lever 454, the elastic plate 453 can be driven to rotate 90°. At the same time, the elastic plate 453 is elastic and can be deformed and separated from the lever 454 after rotating 90°. At this time, the elastic plate 453 drives the first flip plate 452 to rotate 90°. At this time, the inside of the drain pipe 451 is opened. At the same time, the first flip plate 452 drives the second flip plate 455 to rotate synchronously through the transmission gear. The second flip plate 455 rotates 90°. 0° can block the bottom end of the guide tube 45, and the second flip plate 455 and the first flip plate 452 can only rotate up to 90° through the flip block 456 and the limit frame 457, at this time, cleaning can be carried out, and when in use, the movable frame 411 moves toward the direction of the top plate 4. During this process, the lever 454 will push the elastic plate 453 to rotate in the opposite direction. At this time, the directions of the first flip plate 452 and the second flip plate 455 change, so that the inside of the drainage pipe 451 can be closed and the inside of the guide tube 45 can be opened, so that the on and off states of the guide tube 45 and the drainage pipe 451 can be automatically controlled according to the usage status.

[0047] like Figures 3 to 5 As shown, a scraper 46 is provided above the glue discharging plate 421, and a slide bar 461 is fixed to the top and bottom of the scraper 46, and guide grooves 466 are provided on both sides of the movable frame 411, and the slide bar 461 is slidably connected to the inside of the guide groove 466;

[0048] After use, there will be residual glue on the surface of the glue discharge plate 421. At this time, the residual glue needs to be cleaned, and the scraper 46 moves. At this time, the sliding rod 461 moves inside the guide groove 466 to make the bottom of the scraper 46 move close to the glue discharge plate 421. At this time, the glue on the top of the glue discharge plate 421 can be scraped off. In this state, the scraper 46 can block the top of the glue discharge plate 421. When the brush roller 42 is rinsed with cleaning liquid, it will turn to the glue discharge plate 421. At this time, the scraper 46 blocks the brush roller 42 to prevent the cleaning liquid on the surface of the brush roller 42 from dripping into the glue discharge hole of the glue discharge plate 421, so that the surface of the glue discharge plate 421 can be cleaned.

[0049] like Figures 3 to 5 As shown, tension springs 462 are arranged above both ends of the top slide bar 461, one end of the tension spring 462 is fixedly connected to the mobile frame 411 through a connecting block, a second pull rope 463 is fixed to the other end of the tension spring 462, the other end of the second pull rope 463 is fixedly connected to the end of the top slide bar 461, a guide column 465 is arranged below the second pull rope 463, the guide column 465 is fixedly connected to the mobile frame 411, a push plate 464 is fixed to the side of the support plate 11 close to the mobile frame 411, and the push plate 464 is arranged on the side of the scraper 46 away from the brush roller 42;

[0050] During cleaning, the movable frame 411 moves, and during the movement, the movable frame 411 drives the scraper 46 to move at the same time. At this time, the extension block at one end of the top slide bar 461 will contact the push plate 464. At this time, under the push of the push plate 464, the scraper 46 can be moved to clean the surface of the glue outlet plate 421. At the same time, the slide bar 461 pulls the second pull rope 463. Under the action of the guide column 465 changing direction, the second pull rope 463 stretches the tension spring 462. After the cleaning is completed, the push plate 464 and the slide bar 461 are separated when the movable frame 411 is close to the top plate 4. At this time, the tension of the tension spring 462 pulls the second pull rope 463.
