Description

Technical Field

[0001] This utility model relates to the technical field of paper tube winding and processing equipment, and in particular to a longitudinal paper and transverse paper composite device for a fireworks paper tube flat winding machine. Background Technology

[0002] Paper tubes are a crucial component of fireworks; good paper tubes ensure both the desired ignition effect and safety during the display. Modern paper tubes are mostly produced using fully automatic rolling machines. These machines primarily consist of a paper roll, a paper feeding roller assembly, a cutting blade assembly, and a rolling mechanism arranged sequentially along the paper feeding direction. They also include a cutting mechanism arranged parallel to the rolling mechanism along the direction of the rolling pin. The raw paper on the paper roll is held and driven by the paper feeding roller assembly to the cutting mechanism for cutting. Glue is applied before cutting. The cut paper is then fed to the rolling mechanism for winding. The rolling mechanism mainly includes a rolling pin and a tightening mechanism. When starting to roll, the end of the paper is first inserted into the paper insertion gap of the rolling pin. Then, three clamping pins tighten the rolling pin, pressing the paper onto it for winding. After the paper tube is wound, multiple parallel circular blades of the cutting mechanism cut the paper tube into several short paper tubes on the rolling pin. After cutting, the unwinding mechanism pushes the short paper tubes out of the rolling pin.

[0003] In existing technologies, the rolling of fireworks paper tubes includes two methods: oblique rolling and flat rolling. Oblique rolling, also known as twill rolling, is used to produce twill paper tubes. This process is complex, costly, and cannot be used to roll paper tubes with pre-printed labels.

[0004] Flat rolling includes two methods: longitudinal rolling and transverse rolling. Longitudinal rolling means that the rolling mechanism rolls the paper along the longitudinal direction (length direction), while transverse rolling means that the paper is rolled along the transverse direction (width direction, width). See "A Fully Automatic Rolling Machine for Small Diameter Fireworks Paper Tubes" published on June 25, 2014, with authorization announcement number CN203666021 U.

[0005] The problem with existing fireworks paper tube rolling equipment is that both longitudinal and transverse rolling methods have their advantages and disadvantages. For example, longitudinally rolled paper tubes have greater structural strength than transversely rolled paper tubes, effectively meeting high load requirements; however, they require water to wet the sealing end (i.e., the end of the roll paper attached to the outer wall of the paper tube), making them only suitable for highly absorbent paper (such as corrugated paper), and the paper tubes are prone to bending and have a long drying cycle. Existing equipment cannot combine the advantages of both methods. Utility Model Content

[0006] To address the aforementioned drawbacks, the technical problem this utility model aims to solve is to provide a longitudinal and transverse paper composite device for a fireworks paper tube flat winding machine, which effectively optimizes paper tube performance through transverse and longitudinal paper feeding and composite winding. To solve the above technical problem, the technical solution adopted by this utility model is a longitudinal and transverse paper composite device for fireworks paper tube winding, comprising a longitudinal paper feeding mechanism, a transverse paper feeding mechanism, and a composite mechanism: the paper feeding direction of the longitudinal paper feeding mechanism is parallel to the paper winding direction of the winding mechanism; the paper feeding directions of the longitudinal paper feeding mechanism and the transverse paper feeding mechanism are perpendicular to each other; the raw paper on the paper rolls of the two paper feeding mechanisms is driven by the paper feeding roller group through the cutting assembly and then sent to the composite mechanism; a gluing mechanism is provided on the raw paper; the longitudinal and transverse paper cut by the cutting assembly is located in the composite mechanism;

[0007] The composite mechanism includes a partition and a paper pulling assembly: the partition is set above the worktable, with longitudinal and transverse paper located below and above the partition respectively, and the longitudinal and transverse paper are stacked in a staggered manner. The end of the stacked area near the winding pin is the front single-layer paper area, and the end of the stacked area away from the winding pin is the rear single-layer paper area; the paper pulling assembly moves linearly back and forth between the composite mechanism and the winding mechanism, pulling the stacked longitudinal and transverse paper to the winding mechanism of the winding machine for winding.

[0008] The beneficial effects of this invention are as follows: by using staggered overlapping adhesive bonding of longitudinally and transversely fed paper, a crisscrossing composite paper is obtained for paper tube rolling, effectively improving the strength of the paper tube and meeting high load requirements; at the same time, the paper tube is wrinkle-free and not easily bent; sealing quality can be ensured without water wetting, and the drying cycle is short; the single-layer paper area at the end facilitates edge grinding and pre-printing of labels. This solves the pain points of traditional paper tube sealing processes, such as difficulty in sealing, insufficient strength, and high cost, reducing production costs for fireworks manufacturers while ensuring safety during fireworks displays.

[0009] In one embodiment, the paper-pulling assembly is selected from a clamp or a lifting pin bar. The pin bar, when lifting, holds the paper and reciprocates linearly between the laminating mechanism and the winding mechanism; the clamp holds the paper and reciprocates linearly between the laminating mechanism and the winding mechanism.

[0010] To improve the reliability of the adhesive bonding process between the longitudinal and transverse paper, ensuring the bonded paper is smooth, flat, and wrinkle-free, an improved method is to include a paper clamping roller assembly between the bonding mechanism and the roll mechanism. The paper clamping roller assembly can be configured in the following preferred embodiments:

[0011] In one embodiment, the pressure roller assembly is positioned in the boundary area between the composite mechanism and the winding mechanism, with the end of the partition located in front of the paper feed side of the pressure roller assembly. The pressure roller assembly is perpendicular to the winding mechanism. The paper pulling assembly holds the front single-layer paper area, and the paper pulling assembly and the pressure roller assembly feed the longitudinal and transverse paper to the winding mechanism for winding. During the pulling process, the overlapping areas of the longitudinal and transverse paper detach from the partition laterally and are then glued together by the pressure roller assembly. The rotational feeding speed of the pressure roller assembly is synchronized with the pulling speed of the paper pulling assembly. This ensures that the longitudinal and transverse paper are smoothly glued together by the pressure roller assembly after detaching from the partition before winding, and that the pressure roller assembly and the paper pulling assembly work together to feed the paper.

[0012] In one embodiment, the end of the partition extends to the winding mechanism; the paper clamping roller assembly is arranged parallel to the winding pin; the paper pulling assembly pulls the stacking area, drawing the longitudinal and transverse paper between the two rollers of the winding mechanism and the paper clamping roller assembly. During winding, the winding pin causes the stacking area of ​​the longitudinal and transverse paper to detach longitudinally from the partition before being glued together by the paper clamping roller assembly. The paper pulling assembly achieves transverse paper feeding, and the winding process of the winding pin causes the stacking area to detach longitudinally from the partition before being glued together by the paper clamping roller assembly, thus strengthening the bonding between the longitudinal and transverse paper through the paper clamping roller assembly.

[0030] Example 1: See Appendix Figure 1-6This describes a specific structure of the present invention. The winding machine includes a winding mechanism consisting of a winding pin 13, a tightening mechanism, etc., with the winding pin 13 having an axial paper insertion gap. It also includes a cutting mechanism 17 arranged side-by-side with the winding mechanism along the axial direction of the winding pin 13. Furthermore, it includes a longitudinal paper feeding mechanism, a transverse paper feeding mechanism, and a compounding mechanism.

[0031] The longitudinal paper feeding mechanism includes a paper roll (not shown in the figure), a longitudinal paper feeding roller group 1, a longitudinal gluing area 2, and a longitudinal cutter assembly 4 arranged sequentially along the paper feeding direction. The raw paper on the paper roll is held and driven by the longitudinal paper feeding roller group 1 through the longitudinal cutter assembly 4 and then enters the laminating mechanism. After the longitudinal paper 3 is fed to the laminating mechanism, the longitudinal cutter assembly 4 is activated to cut it. Before cutting, the raw paper is coated with glue on the top of the longitudinal gluing area 2.

[0032] The transverse paper feeding mechanism also includes a paper roll (not shown in the figure), a transverse paper feeding roller group 5, a transverse glue coating area 6, and a transverse cutter assembly 8 arranged sequentially along the paper feeding direction. The base paper on the paper roll is held and driven by the transverse paper feeding roller group 5 through the transverse cutter assembly 8 and then enters the laminating mechanism. After the transverse paper 7 is fed to the laminating mechanism, the transverse cutter assembly 8 is activated to cut it. Before cutting, the base paper is glued on the transverse glue coating area 6.

[0033] The paper feeding direction of the longitudinal paper feeding mechanism is parallel to the winding direction of the roll mechanism; the paper feeding directions of the longitudinal paper feeding mechanism and the transverse paper feeding mechanism are perpendicular to each other. It can be seen that when the longitudinal paper 3 and the transverse paper 7 are rolled simultaneously, the longitudinal paper 3 is rolled longitudinally, that is, the roll mechanism rolls the paper along the longitudinal direction (length direction) of the paper roll; the transverse paper 7 is rolled transversely, that is, it is rolled along the transverse direction (width direction) of the paper roll.

[0034] The composite mechanism includes a partition 9 and a paper-pulling assembly. In this example, the paper-pulling assembly uses a cylinder-driven, lifting pin array 22. In this example, the longitudinal distance between the pin array 22 and the longitudinal cutter assembly 4 is approximately 7 cm. In this example, the pin array 22 is located below the paper; when it rises, it catches the paper and then drags it in a linear reciprocating motion between the composite mechanism and the winding mechanism. In other embodiments, the pin array 22 can also be located above the paper, catching it when it descends. In other embodiments, the paper-pulling assembly can also use a clamp to hold the paper and reciprocate linearly between the composite mechanism and the winding mechanism.

[0035] In the example, partition 9 is positioned above workbench 12, vertical paper 3 is positioned on workbench 12 below partition 9, and horizontal paper 7 is positioned above partition 9.

[0036] like Figure 1As shown, the longitudinal paper 3 and the transverse paper 7 are staggered and stacked, forming a centrally crisscrossing stacking area 30. The end of the stacking area 30 closest to the roll spool 13 is the front single-layer paper area 31, and the end of the stacking area 30 furthest from the roll spool 13 is the rear single-layer paper area 32. The front single-layer paper area 31 facilitates insertion into the paper slot of the roll spool 13 for winding, while the rear single-layer paper area 32 facilitates proper sealing. In this example, the front single-layer paper area 31 is a single layer of longitudinal paper 3, and the rear single-layer paper area 32 is a single layer of transverse paper 7.

[0037] The needle row 22 reciprocates linearly between the composite mechanism and the winding mechanism, pulling the stacked longitudinal paper 3 and transverse paper 7 to the winding mechanism, and the front single-layer paper area 31 enters the paper insertion gap of the winding needle 13 for winding.

[0038] To improve the reliability of the adhesive bonding of longitudinal and transverse paper and to ensure that the bonded paper is smooth, flat and wrinkle-free, in this example, a paper clamping roller group 10 is also provided between the bonding mechanism and the roll mechanism.

[0039] In the example, the paper clamping roller assembly 10 is disposed within the boundary zone 33 between the composite mechanism and the winding mechanism, and the end of the partition 9 is located in front of the paper feeding side of the paper clamping roller assembly 10 (e.g., Figure 1 As shown, the end of the partition 9 is located on the left side of the paper feeding side of the paper clamping roller group 10 (the partition 9 does not extend beyond the area of ​​the paper clamping roller group 10 into the winding mechanism); the paper clamping roller group 10 and the winding rod 13 are arranged perpendicularly to each other in the axial direction.

[0040] In the example, the right sides of both the transverse paper 7 and the longitudinal paper 3 are driven by the paper feed rollers 1 and 5 to the space between the two rollers of the paper clamping roller assembly 10. At this time, the two rollers are in the open state to facilitate paper entry. In the example, the rollers on the paper clamping roller assembly 10 are driven upwards into the open state by the roller rocker arm 28. In the example, the linear reciprocating motion of the needle bar 22 can be driven by the sprocket and chain mechanism 29, and through the coaxial transmission of the sprocket, it drives the roller rocker arm 28 to move, realizing the timely switching between the open and closed states of the paper clamping roller assembly 10. Figure 4 As shown.

[0041] The paper pulling assembly—needle row 22—rises and inserts into the front single-layer paper area 31, pulling the longitudinal paper 3 and transverse paper 7 until they are wound onto the roll mechanism. During the pulling process of the needle row 22:

[0042] The two rollers of the paper clamping roller assembly 10 enter a closed state, clamping the transverse paper 7 and the longitudinal paper 3, and begin to rotate and feed the paper. The rotational paper feeding speed of the paper clamping roller assembly 10 is synchronized with the pulling paper feeding speed of the needle row 22. The paper clamping roller assembly 10 and the needle row 22 feed the paper together, so that the stacking area 30 is separated from the end of the partition 9 in the transverse direction and then glued by the paper clamping roller assembly 10 to obtain the longitudinal and transverse composite paper 16. Then the longitudinal and transverse composite paper 16 enters the winding mechanism and is located on the worktable 12, in the area where the partition 9 does not enter the winding mechanism. The front single-layer paper area 31 of the longitudinal and transverse composite paper 16 enters the paper insertion gap of the winding rod 13, the needle row 22 descends and resets, and the winding rod 13 is wound.

[0043] The existing drum mechanism mainly includes a drum rod 13 and a clamping mechanism. The clamping mechanism includes two upper clamping rods 18 and one lower clamping rod 19 arranged in an inverted triangular shape. Under the action of the drive motor and transmission mechanism, the clamping rod rocker arm 21 drives the three clamping rods to reciprocate through the lever fulcrum shaft 14 and the clamping rod lever 27 in sequence, thereby switching between the clamping and opening states.

[0044] In the clamped state: the three clamping rods move toward the drum rod 13 and are tangent to the outer periphery of the drum rod 13 respectively, relying on the elastic clamping of each pressure adjusting spring 23 to tightly hold and wrap the drum rod 13.

[0045] In the open state: the three gripping rods move in opposite directions away from the winding rod 13, so as to facilitate the unwinding of the wound paper tube from the winding rod 13.

[0046] When starting to roll, the end of the paper is first inserted into the paper insertion gap of the roll spool 13. Then, the three clamping rods clamp the paper onto the roll spool 13 for winding. The rolled paper tube is cut by the cutter mechanism 17 and pushed out of the roll spool 13 by the pusher mechanism 15. Cutting and pushing are mature technologies of roll winding machines and will not be described in detail.

[0047] In this invention, since the paper is a thickened cross-laminated paper 16, the aforementioned tightening mechanism can be improved. In this example, the tightening structure of the roll mechanism is equipped with a pressure adjusting component, including a retainer 26 mounted above the middle of the two upper retaining rods 18. In this example, the retainer 26 is a "U"-shaped retainer. The retainer 26 moves synchronously with the two upper retaining rods 18, with the upper parts and sides of the two upper retaining rods 18 located within the retainer 26. Four adjusting screws 24 are threadedly connected to the retainer 26 through threaded holes, and the bottom end of each adjusting screw 24 abuts against the upper and side parts of the two upper retaining rods 18.

[0048] Rotating the adjusting screw 24 allows for fine-tuning of the lateral and downward pressure exerted by the clamping seat on the middle of the two upper clamping rods 18 as needed, restraining the swaying of the middle of the two upper clamping rods 18 during the winding process; this causes a slight bend in the middle of the two upper clamping rods 18, increasing the clamping force of the middle of the two upper clamping rods 18 on the winding rod 13, thereby dispersing wrinkles in the middle of the paper tube during the winding process; thus, it can effectively reduce or even eliminate the occurrence of wrinkles. Moreover, the aforementioned fine-tuning can adapt to the pressure changes of the various pressure adjusting springs 23 during paper tube winding, increasing the tightness of the paper tube.

[0049] In this example, the pressure regulating assembly includes a pressure regulating shaft 20 positioned above two upper clamping rods 18. The pressure regulating shaft 20 is axially parallel to the two upper clamping rods 18. The pressure regulating shaft 20 and the two upper clamping rods 18 are mounted at the same end of the clamping rod lever 27 to achieve synchronous movement with the upper clamping rods 18. The retaining seat 26 is suspended in the middle of the pressure regulating shaft 20 via a connecting screw 25. This not only facilitates the suspension and fixation of the retaining seat but also improves its adaptability to pressure changes of the pressure regulating springs 23, resulting in a better regulating effect.

[0050] Example 2: See Figure 7 This describes another specific mechanism of the present invention. The difference from Embodiment 1 lies in the arrangement of the paper clamping roller group. In this example, the end of the partition 9 extends to the winding mechanism; the paper clamping roller group 10 is arranged parallel to the winding pin 13; the pin row 22 inserts into the stacking area 30 to pull the longitudinal paper 3 and the transverse paper 7 between the two rollers of the winding mechanism and the paper clamping roller group 10 (the two rollers are in the open state).

[0051] When the roll bar 13 is winding, it drives the stacking area 30 of the longitudinal paper 3 and the transverse paper 7 to separate from the partition 9 along the longitudinal direction and then completes the gluing through the paper clamping roller group 10.

[0052] Its features are: the paper pulling assembly simultaneously pulls the longitudinal paper 3 and the transverse paper 7 to the roll mechanism, realizing transverse paper feeding without the need for the paper clamping roller group 10 to work together;

[0053] The winding process of the roll rod drives the stacking area 30 to detach from the partition along the longitudinal direction and then completes the gluing through the paper clamping roller group, so that the longitudinal paper and the transverse paper are strengthened by the paper clamping roller group.

[0054] The difference from Embodiment 1 is that the lateral length of the partition 9 is different. In this example, the end of the partition 9 extends to the winding mechanism. That is, the partition 9 is distributed laterally in the entire area of ​​the composite mechanism and the winding mechanism, and maintains the isolation of the stacking area 30 of the longitudinal paper 3 and the transverse paper 7 until the winding rod 13 starts to wind the paper, dragging the stacking area away from the partition along the longitudinal direction.

[0055] In Embodiment 1, the paper clamping roller group is located in the dividing area between the composite mechanism and the winding mechanism. The end of the partition is located in front of the paper feeding side of the paper clamping roller group, and the partition does not enter the area of ​​the winding mechanism.

[0056] Example 3: See Figure 8 This describes another specific mechanism of the present invention. The difference from Embodiment 2 is the absence of the paper-pressing roller assembly. In this example, the paper-pressing roller assembly and its reinforcing gluing function of Embodiments 1 and 2 are omitted, but this does not affect the achievement of the invention's objective. Everything else is the same as Embodiment 2 and will not be repeated.

[0057] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in detail with reference to the accompanying drawings to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is limited only to the claims and their full scope and equivalents, and not to the specific embodiments disclosed.
