Description

Technical Field

[0001] The present invention relates to an improved invention of a vertical corrugated paper core machine. Background Art

[0002] The invention patent with publication number CN1990224A and invention name "Method for manufacturing vertical corrugated paper core" discloses the processing from paper roll to vertical corrugated paper core; after the paper tape is longitudinally cut and glued, it is changed from horizontal to vertical upright, and the gathered paper tape is kept at a certain pressure by the paper guide wheel to make the paper tapes fully bonded to each other and shaped into a vertical corrugated paper core.

[0003] The above invention patent has the following problems: 1. The width of the single-sided corrugated paper core is greatly narrowed from the vertical corrugated paper core. The width of the base paper is limited. The width of the formed vertical corrugated paper core is only 80 cm, and the output is low. 2. The longitudinal slitting, gluing and side-standing, compounding, drying and shaping of the single-sided corrugated paper core are arranged vertically. The overall structure of the equipment is cumbersome, occupies a large space, and increases the difficulty of side-standing the paper tape, affecting the forming of the side-standing corrugated paper core. 3. The use of a paper guide wheel to gather the paper tape results in insufficient pressing force and uneven pressure, resulting in large differences in the width of the vertical corrugated paper core and low bonding strength. In addition, the two sides of the vertical corrugated paper core are relatively loose, and wrinkles may occur, resulting in a high scrap rate for the vertical corrugated paper core. Summary of the Invention

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a vertical corrugated paper core machine with high output and good processing quality.

In addition, two groups of longitudinal slitting mechanisms and gluing mechanisms are matched with one group of side standing mechanisms, side standing compounding mechanisms, and drying and shaping mechanisms to double the production capacity.

The left and right transmission belts act on the paper tape continuously and the conveying speed of the left and right transmission belts is consistent with that of the lower transmission roller, so that the paper tapes on both sides keep moving forward synchronously with the paper tape in the middle. Therefore, the tension and relaxation of the paper tapes in the side composite area are balanced, and the vertical corrugated paper core after composite is flat and of better quality.

The utility model adjusts the gap between the left and right transmission belts according to the width of the vertical corrugated paper core, thereby meeting the production requirements of vertical corrugated paper cores of different widths.

[0015] Preferably, the spiral directions of the two ends of the screw are opposite; the rotation of the screw can enable the left slide and the right slide to move simultaneously, and move towards or in opposite directions, which has a simpler structure, lower cost, and faster adjustment speed.

[0016] The circumferential surfaces of the left and right transmission wheels are provided with mesh patterns, which increase the friction between the transmission wheels and the transmission belt, thereby ensuring stable output of kinetic energy.

[0020] The frame is provided with a limiting seat, the limiting seat is provided with a limiting groove, and the two ends of the upper pressing roller are placed in the limiting groove. The giving groove plays a longitudinal limiting role on the upper pressing roller, so that the upper pressing roller is kept in the working position.

[0021] Preferably, the second guide rail is provided with a guide groove, the movable seat is provided with a locking bolt, the lower end of the locking bolt passes through the guide groove and is connected to the nut. After the left and right limit members are adjusted, the left and right limit members are locked on the frame by the locking bolt.

[0022] Preferably, the starting ends of the left and right limiters at the entrance of the side-standing composite area are arc-shaped, and the gap between the arc-shaped sections of the left and right limiters gradually narrows along the paper tape pulling direction;

[0023] The gap between the left limiting member and the right limiting member is smaller than the gap between the left transmission wheel and the right transmission wheel.

[0024] The left and right limiters open the entrance of the side-standing laminating area, guiding the paper tape into the narrow side-standing laminating area to improve the laminating quality.

[0025] Preferably, the side-standing mechanism is longitudinally arranged with at least two sets of needle plates. The spacing between the isolation needles on the front needle plate is smaller than that on the rear needle plate, causing the paper web to gradually converge toward the center along the paper web's conveying direction. The spacing between the needle plates adjacent to the side-standing lamination zone is no greater than the width of the side-standing paper web, and the width of the multiple paper webs on the needle plates is greater than the width of the side-standing lamination zone.

[0035] The following describes the details and working principle of the embodiments and examples of the present invention in conjunction with the accompanying drawings. This vertical corrugated paper core machine is provided with a longitudinal slitting mechanism 21, a gluing mechanism 22, a side-standing mechanism 23, a side-standing composite mechanism 24 and a drying and shaping mechanism 25 in sequence along the traction direction; see the attached drawings. Figure 2 The longitudinal slitting mechanism 21, the gluing mechanism 22, and the side standing mechanism 23 are provided with two groups, and are arranged side by side laterally. The side standing compounding mechanism 24 and the drying and shaping mechanism 25 are arranged longitudinally in the center relative to the two groups of longitudinal slitting mechanisms 21, the gluing mechanism 22, and the side standing mechanism 23. The various mechanisms of the utility model are arranged longitudinally in sequence along the traction direction, so that the single-faced corrugated paper core is longitudinally transported from longitudinal slitting to vertical corrugated paper core without the need for 90-degree corner transportation. Not only is the structural distribution more reasonable, it is also more conducive to equipment placement and equipment. Moreover, the two groups of longitudinal slitting mechanisms 21 and gluing mechanisms 22 are matched with a group of side standing mechanisms 23, the side standing compounding mechanism 24, and the drying and shaping mechanism 25 to double the production capacity. However, the overall occupied area and equipment cost of the equipment are not much different from those of the existing vertical corrugated paper core machine, which reduces the production cost overall.

[0036] The side-standing mechanism 23 includes a needle plate 29 and a plurality of spacer pins 30 vertically disposed on the needle plate 29. The spacer pins 30 are arranged in a horizontal line. There are gaps between adjacent spacer pins 30 on the needle plate 29 for the vertically upright paper strip 1 to pass through. In other words, the vertically upright paper core strips after longitudinal slitting pass between adjacent spacer pins 30. To improve the side-standing effect, the side-standing mechanism 23 is longitudinally provided with at least two sets of needle plates 29. The gaps between the spacer pins 30 on the front needle plate 29 are smaller than those on the rear needle plate 29. In the accompanying drawings, three sets of needle plates 29 are provided. As the paper strip 1 is conveyed, the gaps between the spacer pins 30 on the three sets of needle plates 29 gradually narrow, causing the paper strip 1 to gradually converge toward the center. The side-standing composite mechanism 24 includes a traction component and a side pressing component. The side pressing component has a side-standing composite area. The gap on the needle plate 29 adjacent to the side-standing composite area is not greater than the width of the side-standing paper tape 1, and the width of several paper tapes 1 on the needle plate 29 is greater than the width of the side-standing composite area. From longitudinal cutting to entering the side-standing composite area, the isolation needle 30 keeps the paper tape 1 upright vertically, and gradually narrows and tightens the width of the paper tape 1 until the paper tape 1 enters the side-standing composite area, thereby improving the quality of side standing and side-standing composite.

[0037] The traction component includes an upper pressure roller 4 and a lower transmission roller 6, and the lower transmission roller 6 is connected to a first motor that drives it to rotate; the side clamping component includes an annular left transmission belt 3 and a right transmission belt 9, and the left transmission belt 3 and the right transmission belt 9 are upright and wound around the left transmission wheel 2 and the right transmission wheel 8 respectively. The circumferential surfaces of the left transmission wheel 2 and the right transmission wheel 8 are provided with a mesh pattern. The setting of the mesh pattern increases the friction between the transmission wheel and the transmission belt, so that the kinetic energy is output stably. The left transmission wheel 2 is connected to the second motor, and the right transmission wheel 8 is connected to the third motor. The two motors drive the left transmission wheel 2 and the right transmission wheel 8 to rotate respectively, which is convenient for adjustment, assembly and control of the transmission speed. The conveying speed of the left transmission belt 3 and the right transmission belt 9 is the same as the conveying speed of the lower transmission roller 6, that is, the linear speed of the left transmission belt 3, the right transmission belt 9 and the lower transmission roller 6 is the same. The left transmission belt 3 and the right transmission belt 9 are located between the side composite area. The section where the left transmission belt 3 and the right transmission belt 9 contact the paper tape is the transmission section. The inner side 15 of the transmission section of the left transmission belt 3 and the right transmission belt 9 is provided with a left limiter 7 and a right limiter 10, that is, the left transmission belt The transmission sections of the left and right transmission belts 3 and 9 are respectively covered on the outside of the left limit member 7 and the right limit member 10 and remain in a fitted state. The left and right limit members provide support for the transmission sections, so that the width of the side composite area is stable. The paper tape 1 entering the side composite area is gathered and bonded together under the extrusion of the left and right transmission belts and the left and right limit members. The paper tape 1 is subjected to balanced force during the forward movement, and the formed paper core has a stable width; and the conveying speed of the left and right transmission belts is consistent with that of the lower transmission roller, so that the paper tapes 1 on both sides and the middle paper tape 1 keep moving forward synchronously. In this way, the paper tapes 1 in the side composite area are balanced in tension and relaxation, and the composited vertical corrugated paper core is flat. Compared with the background technology, the quality of the composite of the vertical corrugated paper core is greatly improved.

[0038] In order to make the paper tape 1 after cutting enter the side laminating area smoothly, see the attached Figure 5 The starting ends of the left limiter 7 and the right limiter 10 at the entrance of the side-standing composite area are arc-shaped, and the gap between the arc sections 14 of the left limiter 7 and the right limiter 10 gradually narrows along the pulling direction of the paper tape 1; the gap between the left limiter 7 and the right limiter 10 is smaller than the gap between the left transmission wheel 2 and the right transmission wheel 8. The left and right limiters and the left and right transmission belts wrapped around the left and right limiters open the entrance of the side-standing composite area, guiding the paper tape 1 into the narrower side-standing composite area.

[0039] In order to meet the production requirements of vertical corrugated paper cores of different widths, the side pressing component also includes an adjustment assembly for adjusting the gap between the left transmission belt 3 and the right transmission belt 9. The adjustment assembly includes a transversely arranged first guide rail 19 and a screw 13. The screw 13 is rotatably mounted on the frame. The left transmission wheel 2 and the right transmission wheel 8 are rotatably mounted on a left slide 18 and a right slide 20, respectively. The left slide 18 and the right slide 20 are slidably mounted on the first guide rail 19. The left slide 18 and the right slide 20 are threadedly connected to the screw 13, and the two ends of the screw 13 have opposite spiral directions. By rotating the screw 13, the left slide 18 and the right slide 20 move simultaneously along the first guide rail 19, and the two move toward each other, and the width of the side composite area becomes narrower, or the left slide 18 and the right slide 20 move in opposite directions along the first guide rail 19, and the two move away from each other, and the width of the side composite area becomes wider. In this way, the gap between the left and right transmission belts 9 is adjusted according to the width of the vertical corrugated paper core to meet the production requirements of vertical corrugated paper cores of different widths.

[0040] The frame is also provided with a second guide rail for guiding the lateral movement of the left and right limit members 7 and 10; the left and right limit members 7 and 10 are movable seats, and the frame is provided with a support plate 12, and the movable seat is arranged on the support plate 12. The left and right limit members 10 move laterally along the second guide rail to meet the production requirements of vertical corrugated paper cores of different widths. The second guide rail is provided with a guide groove 16, which is arranged on the support plate in the figure. The movable seat is provided with a locking bolt, the lower end of which passes through the guide groove 16 and is connected to a nut. Loosening the nut allows the left and right limit members 7 and 10 to move laterally along the second guide rail. After the left and right limit members 10 are adjusted, the left and right limit members 10 are locked to the frame by the locking bolt and nut, which is easy to operate. The upper pressing roller 4 is provided with a plurality of them, and the entrance of the side composite area is provided with an upper pressing roller 4, the upper pressing roller 4 spans the side pressing component, the movable seat is provided with a make way groove 11, the two ends of the upper pressing roller 4 are placed in the make way groove 11, the lower transmission roller 6 and the upper pressing roller 4 correspond to each other up and down, see the attached Figure 6 , several lower drive rollers 6 are synchronously driven by a transmission chain 17. When the paper strip 1 enters the side-standing lamination zone, it is squeezed and tends to arch upward. The upper pressing roller 4 prevents this upward arching, keeping the vertical corrugated paper core flat. The clearance groove 11 acts as a longitudinal limiter for the upper pressing roller 4, keeping it in its working position. To further limit the upper pressing roller 4, a limit seat 5 is provided on the frame. The limit seat 5 has limit slots. The ends of the upper pressing roller 4 are placed in the limit slots. The limit seat 5 restricts the lateral and longitudinal movement of the upper pressing roller 4, so that the upper pressing roller 4 can only rotate.

[0041] The drying and shaping mechanism 25 includes an oven 27 and a conveyor belt 26. The conveyor belt 26 extends through the oven 27 and is flanked by side baffles 28. The spacing between baffles 28 corresponds to the width of the side laminating area. The laminated vertical corrugated paper cores are conveyed by the conveyor belt 26 through the oven 27. Inside the oven 27, baffles 28 keep the vertical corrugated paper cores compacted and laminated until they are dried and shaped, and then discharged by the conveyor belt 26.

[0042] The working principle of the preferred embodiment is further described below with reference to the accompanying drawings: the continuous single-face corrugated paper core is longitudinally cut into a continuous paper strip 1 by the longitudinal slitting mechanism 21, and then the paper strip 1 is glued by the gluing mechanism 22. After gluing, the paper strip 1 turns from horizontal to vertical and passes through the gap between the isolation needles 30. The paper strip 1 passes through the three groups of isolation needles 30 in sequence, and the adjacent paper strips 1 gradually gather together to form an isosceles trapezoid from the top view. The gathered paper strips 1 enter the side-standing laminating area of the side-standing laminating mechanism 24, and the left transmission belt 3 and the right transmission belt 3 are used to press the paper strips 1 together. Under the compression of the belt 9, the left limiter 7 and the right limiter 10, the paper tape 1 is stably bonded together to form a vertical corrugated paper core. The vertical corrugated paper core is stably conveyed forward under the traction of the upper pressure roller 4 and the lower transmission roller 6 and the conveyance of the left and right transmission belts 9. The vertical corrugated paper core after side compounding enters the oven 27 of the drying and shaping mechanism 25 and is conveyed by the conveyor belt 26. The baffle 28 inside the oven 27 keeps the vertical corrugated paper core in a compressed and compounded state until it is dried and shaped, and finally sent out by the conveyor belt 26.
