Description

Technical Field

[0001] This utility model relates to the technical field of slitting machines, specifically a high-precision slitting machine. Background Technology

[0002] A high-precision slitting machine is a specialized machine used to cut continuous materials into strips. With its high efficiency and precision, it plays a crucial role in numerous industries such as textiles, apparel, packaging, construction, and printing.

[0003] After slitting thin sheets, existing slitting machines require multiple take-up rollers to rewind the slit sheets. These rollers typically rotate synchronously. However, during the rewinding process, issues such as abnormal tension control, tension wheel malfunction, or other reasons can cause the roll to be wound too loosely or too tightly. In such cases, all take-up rollers must be stopped to resolve the problem. This approach severely reduces the rewinding efficiency of thin sheets, greatly limiting the flexibility and continuity of production. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision slitting machine to solve the problem mentioned in the background art that existing slitting machines need to stop all take-up rollers when the roll material is wound too loosely or too tightly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision slitting machine, including a frame,

[0006] A take-up rack is fixed to the side of the frame, and a master stock and a support roller are respectively installed at both ends inside the frame. A slitting roller is installed above the support roller. A rotating rod is installed inside the take-up rack, and a driver is installed outside the take-up rack. Several sets of annular grooves are opened on the rotating rod, and gears are fixed in the annular grooves. Several sets of bushings are sleeved on the rotating rod, and the bushings are located outside the annular grooves. A take-up roller is sleeved on the bushing, and fasteners are installed at both ends of the bushing.

[0007] Preferably, the driver is a motor, and the output end of the motor is connected to one end of the rotating rod.

[0008] In the above technical solution, the motor can drive the rotating rod, bushing and take-up roller to rotate for winding.

[0009] Preferably, several sets of positioning rollers are also provided on both sides of the slitting roller.

[0010] In the above technical solution, the positioning roller can position the thin plate before and after cutting, thus preventing the thin plate from becoming loose and causing the cutting line to be skewed.

[0011] Preferably, the fastener is a limiting bolt, and one end of the limiting bolt is located in the gear tooth groove.

[0012] In the above technical solution, when the limiting bolt is inserted into the size of the gear, it will lock the bushing and make it rotate with the rotating rod. After the limiting bolt is separated from the gear, the bushing will not rotate with the rotating rod when the rotating rod rotates. This makes it convenient to repair the winding roller with problems without affecting the winding operation of other winding rollers.

[0013] Preferably, the take-up roller and the bushing are engaged.

[0014] In the above technical solution, the snap-fit ​​connection method allows for easy disassembly and installation from the bushing after the take-up roller has taken up the thin sheet.

[0015] Preferably, a movable pusher is provided inside the frame, and the masterbatch roll is mounted on the movable pusher.

[0016] In the above technical solution, the movable pusher frame facilitates the replacement of the master stock roll, eliminating the need for disassembly during continuous operation, thus shortening downtime for replacement and improving operational efficiency.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this high-precision slitting machine,

[0018] 1. During use, when the limit bolt engages with the gear, it locks the bushing, causing it to rotate with the rotating rod. After the limit bolt separates from the gear, the bushing will not rotate with the rotating rod, facilitating the maintenance of the malfunctioning take-up roller without affecting the winding operation of other take-up rollers. This effectively reduces the overall downtime caused by a single take-up roller failure, significantly improving production efficiency. Furthermore, maintenance and upkeep can be flexibly arranged according to the actual operating conditions of each take-up roller, eliminating the need to halt the entire production line due to the maintenance of a single take-up roller. This makes equipment maintenance more flexible and further increases the effective operating time of the equipment. Secondly, compared to independent driving of each take-up roller, this technical solution also reduces the need for a drive source, lowering production costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a high-precision slitting machine, such as... Figure 1 , Figure 2 and Figure 3 As shown, a take-up rack 2 is fixed to the side of the frame 1, and a master material roll 3 and a support roller 4 are respectively set at both ends inside the frame 1. A slitting roller 5 is set above the support roller 4. A rotating rod 7 is set inside the take-up rack 2, and a driver is set outside the take-up rack 2. Several sets of annular grooves 9 are opened on the rotating rod 7. Gears 10 are fixed in the annular grooves 9. Several sets of bushings 11 are sleeved on the rotating rod 7, and the bushings 11 are located outside the annular grooves 9. A take-up roller 12 is sleeved on the bushings 11, and fasteners are set at both ends of the bushings 11.

[0025] like Figure 1 and Figure 2 As shown, the driver is motor 8, and the output end of motor 8 is connected to one end of the rotating rod 7.

[0026] like Figure 1 As shown, several sets of positioning rollers 6 are also provided on both sides of the slitting roller 5.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the fastener is a limit bolt 13, and one end of the limit bolt 13 is located in the tooth groove of the gear 10.

[0028] The winding roller 12 and the bushing 11 are engaged.

[0029] The frame 1 is equipped with a movable pusher, and the master material roll 3 is installed on the movable pusher.

[0030] Working principle: In use, first unwind the sheet from the master stock roll 3 and fix one end of the sheet to the take-up roller 12. Then, turn on the motor 8 to drive the rotating rod 7 to rotate. The rotating rod 7 will drive the bushing 11 and the take-up roller 12 to rotate and take up the slit sheet. During the take-up process, if the sheet on one of the take-up rollers 12 is too loose or too tight, first stop the motor 8, then rotate the limiting bolt 13 on the bushing 11 corresponding to the take-up roller 12 to separate the limiting bolt 13 from the gear 10 on the rotating rod 7. At this time, the bushing 11 can be unlocked. Then, start the motor 8 again. The bushing 11 will not rotate with the rotating rod 7, while the other bushings 11 on the rotating rod 7 and the take-up roller 12 will continue to rotate and take up the sheet. After that, the operator can inspect and repair the take-up roller 12 with the problem.

[0031] This completes the entire operation, and anything not described in detail in this specification is prior art known to those skilled in the art.
