Description

Technical Field

[0001] This utility model relates to a high-speed multi-specification rotary cutter slitting machine. Background Technology

[0002] Paper slitting machines are key pieces of equipment in the papermaking, printing, and packaging industries. They are mainly used to slit wide-width rolls of paper into multiple narrow-width rolls. Their core functional modules typically include an unwinding device, a longitudinal slitting device, a traction device, and a cross-cutting device. The unwinding device provides the raw paper rolls to be slit; the longitudinal slitting device cuts the paper longitudinally using a set of circular blades; the traction device uses rollers to control paper tension and transport speed; and the cross-cutting device cuts the paper laterally to a set length using rotating blades or a flying shear mechanism. In existing technologies, the layout of the longitudinal and cross-cutting devices is problematic; they are usually installed far apart along the paper transport direction, resulting in a significant increase in the overall machine length. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a high-speed multi-specification roller slitting machine with a more reasonable structure.

[0004] This high-speed, multi-specification rotary slitting machine includes, in sequence along the material feeding direction, an unwinding device, a longitudinal cutting device, a traction device, and a transverse cutting device. The unwinding device includes an unwinding frame, the longitudinal cutting device includes a longitudinal cutting blade, the traction device includes two traction rollers and a traction power source for driving the traction rollers to rotate, and the transverse cutting device includes a transverse cutting blade. Its key feature is that it includes a slitting frame, on which the longitudinal cutting device, traction device, and transverse cutting device are all mounted. The longitudinal cutting device and the transverse cutting device are located on the front and rear sides of the traction device, respectively, and are close to the traction device. The transverse cutting device includes a first transverse cutting roller and a second transverse cutting roller arranged vertically, each with a transverse cutting blade. The two transverse cutting blades can cooperate to achieve rotary cutting.

[0005] The unwinding device is provided in two units, which are arranged one after the other. A feeding frame is provided above the first unwinding device, and a feeding roller is provided on the feeding frame. A converging roller is provided between the first unwinding device and the slitting device, and the converging roller is lower than the feeding roller and the slitting device.

[0006] The unwinding device includes an unwinding base, on which a guide rail extends to the left and right. An adjusting side plate is slidably mounted on the guide rail. One end of the unwinding frame is rotatably connected to the adjusting side plate. A lifting cylinder is connected to the unwinding frame, and the piston rod of the lifting cylinder is hinged to the adjusting side plate.

[0007] The front of the cross-cutting device is provided with a stacking conveying mechanism, a stacking lifting mechanism, a blocking mechanism, and a supporting mechanism. The rear end of the stacking conveying mechanism is connected to the cross-cutting device for conveying. The blocking mechanism and the supporting mechanism are both located in front of the stacking conveying mechanism. The stacking lifting mechanism is located between the stacking conveying mechanism and the blocking mechanism.

[0008] The stacking conveyor mechanism includes an upper belt and a lower belt; the stacking lifting mechanism includes a stacking discharge belt and a stacking power source that drives the stacking discharge belt to move up and down; the material blocking mechanism includes a material blocking rod; the material supporting mechanism includes a material supporting plate and a pushing power source that drives the material supporting plate to move back and forth, and the material supporting plate has a notch for the material blocking rod to enter.

[0009] According to the present invention, a high-speed multi-specification roller slitting machine can shorten the length of the equipment, make the equipment more compact, and reduce the floor space by placing the traction device between the longitudinal cutting device and the transverse cutting device and bringing them close to each other.

Detailed Implementation

[0011] like Figure 1 As shown, this high-speed multi-specification rotary slitting machine includes, in sequence along the feeding direction, an unwinding device 1, a longitudinal cutting device 3, a traction device 4, and a transverse cutting device 5. The unwinding device 1 is used to release the paper roll, the longitudinal cutting device 3 is used to cut the paper longitudinally, the traction device 4 pulls the paper forward, and the transverse cutting device 5 is used to cut the paper transversely, thus cutting off individual sheets of paper.

[0012] The unwinding device 1 includes an unwinding frame 13, which is existing technology; the slitting device 3 includes a slitting blade, which is fixedly installed (the slitting blade is mounted on a crossbeam, and its left and right positions can be adjusted on the crossbeam to meet the slitting requirements of different paper specifications). As the traction device 4 pulls the paper forward, the slitting blade performs longitudinal slitting on the paper; the traction device 4 includes two traction rollers and a traction power source that drives the traction rollers to rotate. Driven by the traction power source, the traction rollers of the traction device rotate to move the paper forward; Figure 6 As shown, the cross-cutting device 5 includes a cross-cutting blade 52 and a first cross-cutting roller 50 and a second cross-cutting roller 51 arranged vertically. Both the first cross-cutting roller 50 and the second cross-cutting roller 51 have cross-cutting blades 52. Driven by the cross-cutting power source, the first cross-cutting roller 50 and the second cross-cutting roller 51 roll relative to each other (both the first cross-cutting roller 50 and the second cross-cutting roller 51 are connected to gears, and the two gears mesh, so that the first cross-cutting roller 50 and the second cross-cutting roller 51 can rotate synchronously). In this way, the two cross-cutting blades 52 can cooperate to cut the paper (when rotating, the tips of the two cross-cutting blades 52 can cut the paper).

[0013] To make the equipment more compact, such as Figure 2 As shown, the high-speed multi-specification rotary slitting machine includes a slitting frame 19. The longitudinal cutting device 3, the traction device 4, and the transverse cutting device 5 are all installed on the slitting frame 19. The longitudinal cutting device 3 and the transverse cutting device 5 are located on the front and rear sides of the traction device 4, respectively, and are close to the traction device 4. The traction device 4 pulls the paper forward, allowing the longitudinal cutting device 3 to perform longitudinal slitting, while the traction device 4 feeds the paper forward, allowing the transverse cutting device 5 to cut the paper into individual sheets. Since the longitudinal slitting process and the transverse slitting process are very close, not only is the equipment footprint reduced, but the paper cutting accuracy is also higher (if the two processes are too far apart, it will affect the paper feeding direction, resulting in a decrease in slitting accuracy).

[0014] In order to improve the slitting efficiency, such as Figure 1 As shown, there are two unwinding devices 1, arranged one after the other. A feed rack 18 is located above the first unwinding device 1, and a feed roller 17 is mounted on the feed rack 18. The paper from the first unwinding device 1 passes over the second unwinding device 1 via the feed roller 17. Figure 1 and Figure 2 As shown, a material-combining roller 2 is provided between the first unwinding device 1 and the longitudinal cutting device 3. The material-combining roller 2 is lower than the feed roller 17 and the longitudinal cutting device 3. The paper from the first unwinding device 1 and the paper from the second unwinding device 1 are bonded together under the action of the material-combining roller 2, and then enter the longitudinal cutting device 3 together.

[0015] In order to adjust the left and right position of the material roll, such as Figure 3As shown, the unwinding device 1 includes an unwinding base 10, on which a guide rail 12 extends left and right. An adjusting side plate 11 is slidably mounted on the guide rail 12. One end of an unwinding frame 13 is rotatably connected to the adjusting side plate 11. A lifting cylinder 14 is connected to the unwinding frame 13, and the piston rod of the lifting cylinder 14 is hinged to the adjusting side plate 11. By moving the adjusting side plate 11 to its left and right position on the guide rail 12, the left and right position of the unwinding frame 13 can be adjusted. Since the material roll is placed on the unwinding frame 13 (which is equipped with an expansion shaft to support the material roll), the left and right position of the material roll can be adjusted.

[0016] In order to stack the cut-out papers, such as Figure 4 As shown, the front of the cross-cutting device 5 is equipped with a stacking conveyor 6, a stacking lifting mechanism 8, a blocking mechanism 7, and a supporting mechanism 9. The rear end of the stacking conveyor 6 is connected to the cross-cutting device 5. The blocking mechanism 7 and the supporting mechanism 9 are both located in front of the stacking conveyor 6. The stacking lifting mechanism 8 is located between the stacking conveyor 6 and the blocking mechanism 7. The paper cut by the cross-cutting device 5 enters the stacking conveyor 6, which conveys the paper forward. The paper stops moving under the obstruction of the blocking mechanism 7 and falls onto the stacking lifting mechanism 8. As the stacking lifting mechanism 8 gradually descends, the paper is stacked on it and then sent out manually or by a conveyor belt. During this process, the supporting mechanism 9 is used to temporarily support the paper. After the paper is removed, the stacking lifting mechanism 8 rises again to receive the paper, and the supporting mechanism 9 returns to its original position.

[0017] like Figure 4 The stacking conveyor 6 includes an upper belt and a lower belt, which are attached to the paper and convey it forward. The stacking lifting mechanism 8 includes a stacking discharge belt and a stacking power source that drives the stacking discharge belt to move up and down. Driven by the stacking power source, the stacking discharge belt moves up and down, and the paper is stacked on the stacking discharge belt (the stacking discharge belt allows the paper to be automatically fed out). The blocking mechanism 7 includes a blocking rod 70, which can block the paper from moving forward. Figure 5 As shown, the material support mechanism 9 includes a material support plate 90 and a pushing power source that drives the material support plate 90 to move back and forth. The material support plate 90 has a notch 91 into which the baffle rod 70 enters. Driven by the pushing power source, the material support plate 90 can move to the outlet of the stacking conveyor 7. The baffle rod 70 can enter the notch 91 of the material support plate 90. After the material support plate 90 temporarily receives the paper, the material support plate 90 moves backward, and the baffle rod 70 can block the paper to prevent the paper on the material support plate 90 from moving backward with the material support plate 90. When the material support plate 90 moves backward into place, the paper on the material support plate 90 falls onto the stacking lifting mechanism 8.
