Description

Technical Field

[0001] This invention relates to the field of paper packing strip processing technology, and in particular to a paper packing strip edge rolling machine. Background Technology

[0002] In areas with strict environmental protection requirements, packing strips must be made from renewable materials. Manufacturers usually choose paper packing strips, but single-layer paper packing strips are more prone to breakage, so two or more layers must be used. Research has found that rolling the edges of single-layer paper packing strips, so that there are two layers on both sides and a single layer in the middle, can also improve the durability of the paper packing strips.

[0003] There is no dedicated equipment for folding rolled-up paper packing strips; they can only be folded manually, which is inefficient. Summary of the Invention

The width of the edge-curling groove gradually decreases from the paper inlet end to the paper outlet end. The pressing plate is installed on the edge-curling seat through a connector. The pressing plate presses down on the paper packing strip located in the edge-curling groove. The end of the pressing plate located at the paper outlet end is used to limit the width of the edge-curling.

[0015] Furthermore, it also includes an edge-curling and pressing mechanism, which is mounted on the edge-curling seat and located at the paper output end of the edge-curling seat. The edge-curling and pressing mechanism is used to press the edge of the paper packing strip. The edge-curling and pressing mechanism includes an upper pressing wheel, an upper mounting shaft, a lower pressing wheel, and a lower mounting shaft.

Detailed Implementation

[0039] The invention will now be further described with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2As shown, a preferred embodiment of the paper packing strip edge-curling machine of the present invention includes a frame 1, an unwinding mechanism 2, a winding mechanism 8, an edge-curling mechanism 3, a conveying device 4, a heating device 5, a shaping and pressing mechanism 6, and a cooling device 7. The unwinding mechanism 2, winding mechanism 8, edge-curling mechanism 3, conveying device 4, heating device 5, shaping and pressing mechanism 6, and cooling device 7 are all mounted on the frame 1. The unwinding mechanism 2 is used to release unprocessed paper packing strips. The edge-curling mechanism 3 is used to fold and curl the paper packing strips released by the unwinding mechanism 2. The conveying mechanism is used to convey the edge-curled paper packing strips. The heating device 5 is used to heat the edge-curled paper packing strips at the rear end. The shaping and pressing mechanism 6 is used to press the heated paper packing strips to achieve a firm shape. The shaping and pressing mechanism 6 is located between the heating device 5 and the cooling device 7. The cooling device 7 is used to cool the pressed paper packing strips to complete the shaping process. The winding mechanism 8 is used to wind up the cooled paper packing strips.

[0041] The unwinding mechanism 2 includes a first reel 21 and a damper 22. The damper 22 is a conventional rotational damper 22, which is coaxially mounted with the first reel 21, which is mounted on the main mounting frame 12. The damper 22 allows the first reel 21 to rotate more smoothly.

[0042] The frame 1 includes a support leg 11, a main mounting frame 12, a first mounting frame 13, and a second mounting frame 14. The main mounting frame 12 is mounted on the support leg 11, the first mounting frame 13 is mounted on one side of the main mounting frame 12, and the second mounting frame 14 is mounted on the other side of the main mounting frame 12. The unwinding mechanism 2 and the edge-rolling mechanism 3 are mounted on the first mounting frame 13. The conveying device 4, the heating device 5, and the cooling device 7 are all mounted on the main mounting frame 12. The conveying device 4 drives the edge-rolled paper packing strip to pass through the heating device 5 and the cooling device 7 successively. The heating device 5 and the cooling device 7 are located on the same horizontal line to facilitate the conveying device 4 to convey the paper packing strip. The winding mechanism 8 is mounted on the second mounting frame 14.

[0043] like Figure 3 and Figure 4As shown, the first mounting bracket 13 is provided with a first weight-reducing hole 130 to reduce the weight of the first mounting bracket 13. The first mounting bracket 13 includes a first reinforcing plate 131 and a first main mounting bracket 13212. The first reinforcing plate 131 is vertically disposed on the first main mounting bracket 13212 and is used to increase the strength of the first main mounting bracket 13212. Both the first reinforcing plate 131 and the first main mounting bracket 13212 are provided with the first weight-reducing hole 130. The second mounting bracket 14 is provided with a second weight-reducing hole 140 to reduce the weight of the second mounting bracket 14. The second mounting bracket 14 includes a second reinforcing plate 141 and a second main mounting bracket 14212. The second reinforcing plate 141 is vertically disposed on the second main mounting bracket 14212 and is used to increase the strength of the second main mounting bracket 14212. Both the second reinforcing plate 141 and the second main mounting bracket 14212 are provided with the second weight-reducing hole 140.

[0044] like Figures 5 to 7 As shown, the edge-curling mechanism 3 includes an edge-curling seat 31, a pressure plate 32, an edge-curling clamping mechanism 33, and an edge-curling clamping adjustment mechanism 34. The pressure plate 32 is mounted on the edge-curling seat 31 via a connector 37. An edge-curling groove 311 is provided on the edge-curling seat 31 for curling both sides of the paper packing strip. The pressure plate 32 is located within the edge-curling groove 311 and is used to limit the curled length of the paper packing strip. The edge-curling clamping mechanism 33 applies clamping force to the curled portion of the paper packing strip exiting the edge-curling seat 31, thus clamping the curled portion of the paper packing strip. The edge-curling clamping adjustment mechanism 34 is located on the edge-curling seat 31 and abuts against the edge-curling clamping mechanism 33 to increase the clamping force of the clamping mechanism.

[0045] like Figure 8 and Figure 9 As shown, the edge-curling groove 311 is arranged along the length of the edge-curling seat 31 and extends through the edge-curling seat 31 in the length direction, thereby maximizing the length of the edge-curling groove 311. The edge-curling groove 311 has a paper inlet end and a paper outlet end. The left and right side walls of the edge-curling groove 311 serve as guide surfaces to guide the two sides of the paper packing strip to curl. The paper inlet end of the edge-curling groove 311 has a rectangular cross-section, and the paper outlet end has an elongated cross-section, meaning the two side walls of the paper outlet end of the edge-curling groove 311 are arc-shaped. The width of the edge-curling groove 311 gradually decreases from the paper inlet end to the paper outlet end, allowing the two sides of the paper packing strip to gradually curl within the edge-curling groove 311 until they are rotated 180°, thus completing the edge curling of the paper packing strip. In other embodiments, such as... Figure 10 As shown, the paper feed end of the crimping groove 311 can also have an arc-shaped cross-section.

[0046] The pressing plate 32 is pressed onto the paper packing strip located in the edge curling groove 311, and the end of the pressing plate 32 located at the paper output end is used to limit the width of the edge curling.

[0047] like Figure 7 As shown, the paper output end of the edge-curling seat 31 is provided with symmetrically arranged mounting portions 35, and the edge-curling pressing mechanism 33 is mounted on the mounting portions 35. Each mounting portion 35 extends towards the output end to form a connecting portion 36, and the pressing plate 32 is connected to the connecting portion 36. The connecting member 37 is mounted on the connecting portion 36 of the edge-curling seat 31 by a shaft pin, connecting the pressing plate 32 to the edge-curling seat 31. The shaft pin facilitates the disassembly and assembly of the connecting member 37, thereby enabling the disassembly and assembly of the pressing plate 32, which is convenient for the initial insertion of the paper packing strip into the edge-curling groove 311. The edge-curling seat 31 is provided with an opening 312, which is vertically downward, so that the opening 312 communicates with the edge-curling groove 311. The pressing plate 32 is located in the opening 312, so that the pressing plate 32 can enter the edge-curling groove 311 through the opening 312 to press the paper packing strip, and can also be installed on the connecting portion 36 of the edge-curling seat 31 by the connecting member 37. The length of the opening 312 is less than the length of the curling groove 311, which facilitates the formation of the positioning end face and quick positioning of the pressing plate 32.

[0048] The connector 37 is fixed to the pressure plate 32 by bolts, which facilitates the replacement of the pressure plate 32.

[0049] like Figure 11 As shown, the edge-curling and pressing mechanism 33 is provided on the edge-curling seat 31. The edge-curling and pressing mechanism 33 is located at the paper output end of the edge-curling seat 31. The edge-curling and pressing mechanism 33 is used to press the edge of the paper packing strip. Specifically, the edge-pressing mechanism 33 includes an upper pressing wheel 331, an upper mounting shaft 332, a lower pressing wheel 333, and a lower mounting shaft 334. The upper mounting shaft 332 and the lower mounting shaft 334 are both mounted on the edge-pressing seat 31. The upper pressing wheel 331 is rotatably mounted on the upper mounting shaft 332, and two upper pressing wheels 331 are mounted on the upper mounting shaft 332. The lower pressing wheel 333 is rotatably mounted on the lower mounting shaft 334, and two lower pressing wheels 333 are mounted on the lower mounting shaft 334. The upper mounting shaft 332 and the lower mounting shaft 334 are located on the same vertical line, ensuring that the upper pressing wheel 331 and the lower pressing wheel 333 at the same end can be aligned, which facilitates pressing the two sides of the paper packing strip.

[0050] The edge-rolling seat 31 is provided with a mounting shaft hole 313 and an adjusting mounting hole. The mounting shaft hole 313 has a certain length, and the upper mounting shaft 332 is located within the mounting shaft hole 313, floating within it. The adjusting mounting hole communicates with the mounting shaft hole 313, and the edge-rolling clamping adjustment mechanism 34 is installed within it. The edge-rolling clamping adjustment mechanism 34 abuts against the upper mounting shaft 332, applying pressure to the upper mounting shaft 332 to keep the upper clamping roller 331 on the upper mounting shaft 332 always in its lowest position. The lowest position of the upper clamping roller 331 changes with the thickness of the paper packing strip; the thinner the paper packing strip, the lower the lowest position of the upper clamping roller 331; the thicker the paper packing strip, the higher the lowest position of the upper clamping roller 331. The floating upper clamping roller 331 can automatically adapt to paper packing strips of different thicknesses.

[0051] like Figure 12 As shown, the hemming and pressing adjustment mechanism 34 includes a spring 341 and an adjusting post 342. Both the spring 341 and the adjusting post 342 are screwed into the adjusting mounting hole. The upper end of the spring 341 abuts against the adjusting post 342, and the lower end of the spring 341 directly abuts against the upper mounting shaft 332. The spring 341 applies a downward pressure to the upper mounting shaft 332. In other embodiments, such as... Figure 10 As shown, the lower end of the spring 341 can also abut against the upper mounting shaft 332 via a clamping post 343. The adjusting post 342 is screwed into the adjusting mounting hole, and the compression of the spring 341 can be adjusted by rotating the adjusting post 342, thereby changing the elastic force of the spring 341 and thus changing the pressure applied by the spring 341 to the upper mounting shaft 332.

[0052] like Figure 1 and Figure 2As shown, the conveying device 4 includes an upper conveyor belt 41, an upper conveyor wheel 42, a lower conveyor belt 43, a lower conveyor wheel 44, a synchronous belt 45, a synchronous pulley 46, and a conveyor motor 47. The upper conveyor wheel 42 and the lower conveyor wheel 44 are both located on the front side of the main mounting frame 12. There are two upper conveyor wheels 42, and the upper conveyor belt 41 is mounted on the two upper conveyor wheels 42. There are also two lower conveyor wheels 44, and the lower conveyor belt 43 is mounted on the two lower conveyor wheels 44. There are two synchronous pulleys 46, which are respectively mounted on the corresponding upper conveyor wheel 42 and lower conveyor wheel 44. That is, one upper conveyor wheel 42 is connected to the synchronous pulley 46 via a rotating shaft, and the lower conveyor wheel 44 corresponding to that upper conveyor wheel 42 is connected to the other synchronous pulley 46 via a rotating shaft. The synchronous belt 45 is mounted on the two synchronous pulleys 46. The conveyor motor 47 is mounted on the rear side of the main mounting frame 12 of the frame 1. The conveyor motor 47 is connected to a synchronous pulley 46, and the conveyor motor 47 drives the synchronous pulley 46 to rotate. The gap between the upper conveyor belt 41 and the lower conveyor belt 43 is basically the same as the thickness of the rolled edge of the paper packing strip, so as to move the paper packing strip. The conveyor motor 47 drives the synchronous pulley 46 to rotate, and the synchronous pulley 46 drives another synchronous pulley 46 to rotate through the synchronous belt 45. The two synchronous pulleys 46 and the synchronous belt 45 drive the upper conveyor wheel 42 and the lower conveyor wheel 44 to rotate. The upper conveyor wheel 42 and the lower conveyor wheel 44 and the synchronous belt 45 drive the upper conveyor belt 41 and the lower conveyor belt 43 to rotate synchronously, thereby conveying the paper packing strip.

[0053] The heating device 5 includes an upper heating plate 51 and a lower heating plate 52, both of which are mounted on the main mounting frame 12. The upper heating plate 51 is used to heat the paper packing strip from above and is located inside the upper conveyor belt 41. The lower heating plate 52 is located inside the lower conveyor belt 43 and is used to heat the paper packing strip from below.

[0054] The shaping and pressing mechanism 6 includes an upper shaping pressure roller 61 and a lower shaping pressure roller 62. Both the upper shaping pressure roller 61 and the lower shaping pressure roller 62 are mounted on the main mounting frame 12. The upper shaping pressure roller 61 and the lower shaping pressure roller 62 cooperate to press the heated paper packing strip.

[0055] The cooling device 7 includes a cooling fan 71, an upper cooling plate 72, and a lower cooling plate 73. The upper cooling plate 72 and the lower cooling plate 73 are both installed on the front side of the main mounting frame 12, and the cooling fan 71 is installed on the rear side of the main mounting frame 12. The main mounting frame 12 is provided with ventilation holes at the corresponding positions of the cooling fan 71. The upper cooling plate 72 and the lower cooling plate 73 are both located at the ventilation holes. The upper cooling plate 72 and the lower cooling plate 73 are both provided with heat dissipation holes 74. The cooling fan 71 blows cooling air into the heat dissipation holes 74 of the upper cooling plate 72 and the lower cooling plate 73 to dissipate heat from the upper cooling plate 72 and the lower cooling plate 73. The upper cooling plate 72 and the lower cooling plate 73 are in contact with the top and bottom surfaces of the paper packing strip, respectively, to dissipate heat from the paper packing strip.

[0056] The winding mechanism 8 includes a second reel 81 and a winding motor 82. The winding motor 82 is connected to the second reel 81 and is mounted on the main mounting frame 12. The winding motor 82 is a torque motor, which facilitates control of the winding force and enables the second reel 81 to rotate smoothly.

[0057] The paper packing strip is released from the first reel 21 and then enters the edge-rolling groove 311. It enters from the feed end of the edge-rolling groove 311. Under the action of the specific structure of the edge-rolling groove 311, the paper packing strip gradually rolls and folds. When the paper packing strip comes out from the discharge end of the edge-rolling groove 311, the folding of both sides of the paper packing strip is completed, that is, the edge rolling is completed. The edge rolling width is limited by the pressure plate 32 to ensure the width of the edge rolling, that is, the edge rolling part is located on both sides of the pressure plate 32. Then, the upper pressure roller 331 and the lower pressure roller 333 are used for initial pressing. After the paper packing strip is edge-rolled, it continues to move between the upper conveyor belt 41 and the lower conveyor belt 43. The upper and lower conveyor belts pull the paper packing strip, which is heated as it passes the upper heating plate 51 and the lower heating plate 52. It is then further compressed between the upper and lower shaping rollers 61 and 62, and finally cooled by the upper and lower cooling plates 72 and 73, completing the final shaping. The shaped paper packing strip is then wound up by the second reel 81. Using mechanical equipment instead of manual edge rolling is highly efficient and produces high-quality rolls.

[0058] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structures made using the contents of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of the present invention.
