Description

Technical Field

[0001] This utility model belongs to the field of roll paper manufacturing, and in particular relates to a roll paper pressing and forming device. Background Technology

[0002] When processing roll paper into paper corner protectors, it is necessary to squeeze it to form the roll paper, that is, to press the prepared cardboard to form a roll shape. The paper roll forming machines on the market all rely on manual placement of paper on heating strips or manual pushing of cardboard and manual pushing of pressing molds for forming, which has high labor costs and low work efficiency.

[0003] For example, a Chinese utility model patent discloses a paper tube forming machine [application number CN201920867257.5], which includes a machine platform, a conveyor belt on the machine platform for conveying flat paper tubes, the flat paper tubes being formed by joining paper sheets end to end and flattening them, a lower guide strip above the conveyor belt that passes longitudinally through the flat paper tube and lightly presses down on the lower part of the flat paper tube, an upper guide strip above the lower guide strip for expanding the flat paper tube upwards, a middle guide rod between the lower and upper guide strips, and a flattening device on the machine platform for pressing the flat paper tube flat again. The forming machine of this utility model has a simple structure, especially since the lower guide strip, upper guide strip, and middle guide rod are all detachably fixed to the clamping block by bolts. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a roll paper pressing and forming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A roll paper pressing and forming device includes a base table, a pressure plate on the base table, a paper feeding channel between the pressure plate and the base table, an outer forming cylinder on the base table, an inner forming cylinder inside the outer forming cylinder, a forming channel between the outer forming cylinder and the inner forming cylinder, the inlet of the forming channel being connected to the outlet of the paper feeding channel, and a pusher plate sliding on the base table at the inlet of the paper feeding channel, the pusher plate being connected to a paper feeding transverse drive.

[0006] In the aforementioned roll paper pressing and forming device, the inner forming cylinder is provided with a fixed structure, part of which can extend into the forming channel and abut against the roll paper, and the inner forming cylinder is also connected to a drive motor.

[0007] In the aforementioned roll paper pressing and forming device, the fixing structure includes an extension rod that slides within an inner forming cylinder. The extension rod is slidably connected to the inner forming cylinder. A pressure block is provided at the end of the extension rod near the forming channel. The pressure block can extend into the forming channel. The fixing structure also includes an unfolding structure connected to the extension rod and disposed within the inner forming cylinder.

[0008] In the aforementioned roll paper pressing and forming device, the unfolding structure includes a transverse block that slides on the inner forming cylinder. The transverse block is provided with a plurality of inclined grooves. The end of the extension rod away from the forming channel extends into the corresponding inclined groove and is slidably connected thereto. The transverse block is rotatably connected to the output shaft of the unfolding transverse drive.

[0009] In the aforementioned roll paper pressing and forming device, the end face of the pressure block that contacts the roll paper is provided with a rubber layer that has deformation capability.

[0010] In the above-mentioned roll paper pressing and forming device, the two ends of the forming channel pass through the outer forming cylinder and the inner forming cylinder, and one end of the forming channel has a paper output frame that is slidably set on the base table. The paper output frame can extend into the forming channel and is connected to the paper output transverse drive.

[0011] In the aforementioned roll paper pressing and forming device, the paper output frame has a notch.

[0012] In the aforementioned roll paper pressing and forming device, the pressure plate is connected to the lifting drive.

[0013] In the aforementioned roll paper pressing and forming device, the upper and lower sides of the forming channel have several rotating rollers respectively arranged on the pressure plate and the base table.

[0014] In the aforementioned roll paper pressing and forming device, the upper and lower sides of the forming channel have several spray heads respectively arranged on the pressure plate and the base table.

[0015] Compared with existing technologies, the advantages of this utility model are: It eliminates the need for manual placement of paper on the heating strip, manual pushing of the cardboard, and manual pushing of the pressing mold for forming.

[0016] The fixed structure presses against and holds the cardboard in place. Then, the drive motor rotates the inner forming cylinder relative to the outer forming cylinder, thereby driving the cardboard to continue moving into the forming channel. This overcomes the limited extension distance of the output shaft of the paper feed transverse drive and the increased friction between the cardboard and the inner wall of the forming channel, and also prevents the cardboard from folding.

[0017] The rubber layer prevents the pressure block from damaging the cardboard and increases the friction between the cardboard and the inner forming cylinder, improving the fixing effect and preventing relative slippage when the inner forming cylinder rotates and moves the cardboard.

[0018] By using rotating rollers, the friction between the cardboard and the inner wall of the paper feed channel is reduced, and the spray head can spray water mist onto the cardboard, increasing the cardboard's deformability. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This embodiment provides a roll paper pressing and forming device, combined with Figure 1-3 As shown, the device includes a base table 10, a pressure plate 11 on the base table 10, a paper feed channel 12 between the pressure plate 11 and the base table 10, an outer forming cylinder 13 on the base table 10, an inner forming cylinder 14 inside the outer forming cylinder 13, a forming channel 15 between the outer forming cylinder 13 and the inner forming cylinder 14, the inlet of the forming channel 15 being connected to the outlet of the paper feed channel 12, a pusher plate 16 sliding on the base table 10 at the inlet of the paper feed channel 12, and the pusher plate 16 being connected to a paper feed transverse drive 17.

[0023] In this embodiment, the cardboard is inserted into the paper feed channel 12. The pusher 16 moves forward under the push of the output shaft of the paper feed traverse driver 17, thereby pushing the cardboard to continue moving along the paper feed channel 12. As the cardboard moves, it moves into the forming channel 15. A heating device can be provided on the inner wall of the forming channel 15. The heating of the cardboard increases its deformability until the cardboard is fully inserted into the forming channel 12 and formed. There is no need for manual placement of paper on the heating strip, manual pushing of the cardboard, or manual pushing of the pressing mold for forming.

[0024] The inner forming cylinder 14 is provided with a fixing structure 18. Part of the fixing structure 18 can extend into the forming channel 15 and abut against the roll of paper. The inner forming cylinder 14 is also connected to a drive motor 19.

[0025] In this embodiment, after the cardboard moves into the forming channel 16, the output shaft of the paper feed transverse drive 17 extends a limited distance and the friction between the cardboard and the inner wall of the forming channel 15 increases. The fixing structure 18 presses against the cardboard and holds it in place. Then, the drive motor 19 operates to make the inner forming cylinder 14 rotate relative to the outer forming cylinder 13, thereby driving the cardboard to continue moving into the forming channel 15. This overcomes the limited extension distance of the output shaft of the paper feed transverse drive 17 and the increased friction between the cardboard and the inner wall of the forming channel 15, and also prevents the cardboard from folding.

[0026] The fixing structure 18 includes an extension rod 20 that slides within the inner forming cylinder 14. The extension rod 20 is slidably connected to the inner forming cylinder 14. A pressure block 21 is provided at the end of the extension rod 20 near the forming channel 15. The pressure block 21 can extend into the forming channel 15. The fixing structure 18 also includes an unfolding structure that is connected to the extension rod 20 and disposed within the inner forming cylinder 14.

[0027] In this embodiment, after the cardboard moves into the forming channel 16, the unfolding structure 18 works to move the extension rod 20 toward the forming channel 15, thereby causing the pressure block 21 to move toward the forming channel 15 and abut against the cardboard. The pressure block 21 presses against the cardboard and fixes the cardboard by friction. As the inner forming cylinder 14 rotates, it continues to move the cardboard.

[0028] The unfolding structure includes a transverse block 22 that slides on the inner forming cylinder 14. The transverse block 22 has several inclined grooves 23. The end of the extension rod 20 away from the forming channel 15 extends into the corresponding inclined groove 23 and is slidably connected to it. The transverse block 22 is rotatably connected to the output shaft of the unfolding transverse driver 24.

[0029] In this embodiment, after the cardboard moves into the forming channel 16, the transverse drive 24 is deployed to cause the transverse block 22 to move laterally relative to the inner forming cylinder 14. The guide action of the inclined groove 23 causes the extension rod 20 to move with the pressure block 21 into the forming channel 15 and abut against the cardboard.

[0030] The pressure block 21 has a rubber layer with deformation capability on the end face that contacts the roll of paper.

[0031] In this embodiment, the rubber layer can prevent the pressure block 21 from crushing the cardboard and can increase the friction between the cardboard and the cardboard, thereby improving the fixing effect and preventing relative sliding when the inner forming cylinder 14 rotates and moves the cardboard.

[0032] The forming channel 15 has an outer forming cylinder 13 and an inner forming cylinder 14 passing through both ends. One end of the forming channel 15 has a paper output frame 25 that is slidably disposed on the base table 10. The paper output frame 25 can extend into the forming channel 15 and is connected to the paper output transverse drive 26.

[0033] In this embodiment, after the cardboard is formed in the forming channel 15, the handling transverse drive 26 operates to push the paper output frame 25 into the forming channel 15, thereby causing the paper output frame 25 to push the formed roll of paper out of the forming channel 15.

[0034] The paper output frame 25 has a notch.

[0035] In this embodiment, the notch is used to prevent collision with the unfolding transverse drive 24.

[0036] The pressure plate 11 is connected to the lifting driver 27.

[0037] In this embodiment, in the initial stage, it is only necessary to place the cardboard on the base table 10, and move the pressure plate 11 downward by operating the lifting drive 27.

[0038] The forming channel 15 has several rotating rollers 28 on the upper and lower sides respectively arranged on the pressure plate 11 and the base table 10.

[0039] In this embodiment, the friction between the cardboard and the inner wall of the paper feed channel 12 is reduced by the rotating roller 28.

[0040] The molding channel 15 has several spray nozzles 29 on its upper and lower sides, respectively mounted on the pressure plate 11 and the base table 10.

[0041] In this embodiment, the spray head 29 can spray water mist onto the cardboard, increasing the cardboard's deformability.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0043] Although this article frequently uses terms such as base table 10, pressure plate 11, paper feed channel 12, outer forming cylinder 13, inner forming cylinder 14, forming channel 15, push plate 16, paper feed transverse drive 17, fixing structure 18, drive motor 19, extension rod 20, pressure block 21, transverse block 22, inclined groove 23, unfold transverse drive 24, paper output frame 25, paper output transverse drive 26, lifting drive 27, rotating roller 28, spray head 29, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
