Description

Technical Field

[0001] This utility model relates to a high-speed thin material slitting machine. Background Technology

[0002] High-speed paper slitting machines are core equipment in the printing, packaging, and paper processing industries, used to continuously slit, cross-cut, and stack wide-width rolls of paper into stacks of specified dimensions. Traditional slitting machines typically employ a linear series layout, consisting of an unwinding device, a slitting device (longitudinal slitting blade assembly), a traction device, a cross-cutting device, and a stacking conveyor. The overall length of the machine is quite long. While this design can meet the demands of high-speed continuous production, it presents the following technical problems: the linear layout of existing slitting machines leads to a direct conflict between the equipment length and the workshop width. In small to medium-sized production sites, the equipment occupies a significant amount of effective working space, forcing companies to compress material storage areas, employee operating areas, and logistics channels, and even violating fire safety regulations regarding equipment spacing. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a high-speed thin material slitting machine that can achieve a reasonable layout.

[0004] This high-speed thin-material slitting machine includes, in sequence along the material feeding direction, a first unwinding device, a slitting device, a first traction device, a second traction device, and a cross-cutting device. The first unwinding device includes a first unwinding frame, the slitting device includes a slitting blade, the first traction device includes two first traction rollers and a first traction power source for driving the first traction rollers to rotate, the second traction device includes two second traction rollers and a second traction power source for driving the second traction rollers to rotate, and the cross-cutting device includes a cross-cutting blade. The machine is characterized in that: a corner feeding device is provided between the first traction device and the second traction device. The corner feeding device includes a feeding support and multiple first inclined rollers and a corresponding number of first straight rollers mounted on the feeding support. The first inclined rollers and the first straight rollers are arranged vertically.

[0005] A second unwinding device is provided in front of the first unwinding device. The second unwinding device includes a second unwinding frame. A plurality of second inclined rollers and a corresponding number of second straight rollers are installed on the feeding support. The second inclined rollers and the second straight rollers are arranged vertically. The inclination direction of the second inclined rollers is at an angle to the traction direction of the first traction device. The axial direction of the second straight rollers is the same as the traction direction of the first traction device. The traction direction of the second traction device is perpendicular to the axial direction of the second straight rollers. The first inclined roller and the second inclined roller are located at the upper and lower ends of the feeding support, respectively. The first straight roller is located below the first inclined roller, and the second straight roller is located above the second inclined roller and below the first straight roller.

[0007] The cross-cutting device includes a first cross-cutting roller and a second cross-cutting roller arranged vertically.

The first cross-cutting roller and the second cross-cutting roller rotate relative to each other under the drive of the cross-cutting power source, and the two cross-cutting blades can cooperate to achieve rolling cut.

[0008] A stacking conveyor is provided in front of the cross-cutting device.

Detailed Implementation

[0014] like Figure 1 As shown, this high-speed thin-sheet slitting machine includes, in sequence along the feeding direction, a first unwinding device 1, a slitting device 3, a first traction device 4, a second traction device 6, and a cross-cutting device 7. The first unwinding device 1 is used to release the paper roll, the slitting device 3 is used to longitudinally slit the paper, the first traction device 4 pulls the paper forward so that the slitting device 3 can perform slitting normally, and the second traction device 6 continues to pull the paper forward so that the subsequent cross-cutting device 7 can perform transverse slitting, thus cutting off individual sheets of paper; "thin-sheet" in the high-speed thin-sheet slitting machine refers to relatively thin paper.

[0015] like Figure 1 As shown, the first unwinding device 1 includes a first unwinding frame, which is prior art; the slitting device 3 includes a slitting blade, which is fixedly installed. As the first traction device 4 pulls the paper forward, the slitting blade cuts the paper longitudinally; the first traction device 4 includes two first traction rollers and a first traction power source that drives the first traction rollers to rotate. Driven by the first traction power source, the two first traction rollers rotate and cooperate to move the paper forward; the second traction device 6 includes two second traction rollers and a second traction power source that drives the second traction rollers to rotate. Driven by the second traction power source, the two second traction rollers rotate and cooperate to move the paper forward; the cross-cutting device 7 includes a cross-cutting blade, which can be a roller cutter or a straight cutter. The cross-cutting blade cuts the paper laterally.

[0016] To make the overall layout more reasonable, such as Figure 1 As shown, a corner feeding device 5 is provided between the first traction device 4 and the second traction device 6, such as... Figure 2 and Figure 3 As shown, the corner feeding device 5 includes a feeding support 50 and multiple first inclined rollers 51 and a corresponding number of first straight rollers 52 mounted on the feeding support 50. The first inclined rollers 51 and the first straight rollers 52 are arranged vertically. The inclination direction of the first inclined rollers 51 forms an angle (generally 45°) with the traction direction of the first traction device 4. The axial direction of the first straight rollers 52 is the same as the traction direction of the first traction device 4, and the traction direction of the second traction device 6 is perpendicular to the axial direction of the first straight rollers 52. During feeding, the paper first wraps around the first inclined rollers 51, then around the first straight rollers 52, and then enters the second traction device 6 and the cross-cutting device 7, thus forming a corner path for the paper. With this structure, the slitting device 3, the first traction device 4, the second traction device 6, and the cross-cutting device 7 can form an L-shaped layout, thereby significantly shortening the overall length of the machine and improving site adaptability.

[0017] In order to improve the slitting efficiency, such as Figure 1 As shown, a second unwinding device 2 is provided in front of the first unwinding device. The second unwinding device 2 includes a second unwinding frame. The second unwinding device 2 is prior art. Figure 2 and Figure 3 As shown, multiple second inclined rollers 53 and a corresponding number of second straight rollers 54 are installed on the material feeding support 50. The second inclined rollers 53 and the second straight rollers 54 are arranged vertically. The inclination direction of the second inclined rollers 53 forms an angle with the traction direction of the first traction device 4, the axial direction of the second straight rollers 54 is the same as the traction direction of the first traction device 4, and the traction direction of the second traction device 6 is perpendicular to the axial direction of the second straight rollers 54. Figure 3 As shown, the first inclined roller 51 and the second inclined roller 53 are located at the upper and lower ends of the feeding support 50, respectively. The first straight roller 52 is located below the first inclined roller 51, and the second straight roller 54 is located above the second inclined roller 53 and below the first straight roller 52. The corner feeding method of the upper and lower continuous sheets of paper is the same. Finally, the upper and lower continuous sheets of paper are merged together under the action of the guide roller 57 and enter the second traction device 6 and the cross-cutting device 7, which can improve the paper cutting efficiency.

[0018] In order to adjust the left and right positions of the first inclined roller 51 to meet the slitting requirements of different sizes of paper, such as Figure 2 As shown, a first guide rail 55 is installed on the material feeding support, and a first slide block 56 is slidably provided on the first guide rail 55. A first inclined roller 51 is connected to the first slide block 56. By moving the first slide block 56 to the left and right position on the first guide rail 55, the left and right position of the first inclined roller 51 can be adjusted. Similarly, in order to adjust the left and right position of the second inclined roller 53, a second guide rail is installed on the material feeding support 50, and a second slide block is slidably provided on the second guide rail. The second inclined roller 53 is connected to the second slide block.

[0019] like Figure 2 As shown, the cross-cutting device 7 includes a first cross-cutting roller 70 and a second cross-cutting roller 71 arranged vertically, as follows: Figure 5 As shown, both the first cross-cutting roller 70 and the second cross-cutting roller 71 have cross-cutting blades 72. Driven by the cross-cutting power source, the first cross-cutting roller 70 and the second cross-cutting roller 71 rotate relative to each other (both the first cross-cutting roller 70 and the second cross-cutting roller 71 are connected to gears, and the two gears mesh, so the first cross-cutting roller 70 and the second cross-cutting roller 71 can rotate synchronously). The two cross-cutting blades 72 can cooperate to roll and cut the paper (when rotating, the blade tips of the two cross-cutting blades 72 cooperate to cut the paper), thus cutting off sheets of paper from a continuous sheet of paper.

[0020] In order to stack the cut-out papers, such as Figure 1 As shown, a stacking conveyor 8 is provided in front of the cross-cutting device 7. Figure 4 As shown, the stacking conveyor 8 includes a belt conveyor 80, a stacking lifting mechanism 81, a blocking mechanism 82, and a supporting mechanism 83. The rear end of the belt conveyor 80 is connected to the cross-cutting device 7. The blocking mechanism 82 and the supporting mechanism 83 are both located in front of the belt conveyor 80, and the stacking lifting mechanism 81 is located between the belt conveyor 80 and the blocking mechanism 82. The paper, after being cut by the cross-cutting device 7, enters the belt conveyor 80, which conveys the paper forward. The paper stops moving under the obstruction of the blocking mechanism 82 and falls onto the stacking lifting mechanism 81. As the stacking lifting mechanism 81 gradually descends, the paper is stacked on it and then sent out manually or by a conveyor belt. During this process, the supporting mechanism 83 temporarily supports the paper. After the paper is removed, the stacking lifting mechanism 81 rises again to receive the paper, and the supporting mechanism 83 returns to its original position.

[0021] The belt conveyor mechanism 80 includes an upper conveyor belt and a lower conveyor belt, which are attached to the paper and convey it forward. The stacking and lifting mechanism 81 includes a stacking surface and a stacking power source that drives the stacking surface to move up and down. Driven by the stacking power source, the stacking surface moves up and down, and the paper is stacked on the stacking surface. The material blocking mechanism 82 includes a material blocking rod that can block the paper from moving forward. The material supporting mechanism 83 includes a material supporting plate and a pushing power source that drives the material supporting plate to move back and forth. Driven by the pushing power source, the material supporting plate can move to the discharge port of the belt conveyor mechanism 80 for temporary paper receiving.

[0022] To enable automatic feeding of paper from the stacked surface, such as Figure 3The stacking surface is a stacking conveyor belt, which is connected to a stacking conveyor power source that drives the stacking conveyor belt. Driven by the stacking conveyor power source, the stacking conveyor belt can deliver the stacked papers.

[0023] To reduce the overall footprint of the machine in the horizontal direction, such as Figure 3 As shown, the conveying direction of the stacking conveyor belt is perpendicular to the conveying direction of the belt conveyor mechanism 80. This allows the stacking conveyor belt to feed the paper longitudinally. A discharge conveyor device 9, which includes a discharge conveyor belt, is connected to the front of the stacking conveyor belt. After the stacking conveyor belt conveys the paper, it enters the discharge conveyor belt, which then transports the stacked paper to the outside for easy handling by workers or direct connection to the boxing conveyor line for boxing.
