Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a high-efficiency slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide films into multiple narrow films. It is widely used in industries such as packaging, printing, and electronics. Its emergence has greatly improved production efficiency and product quality, making it an indispensable tool in modern industrial production.

[0003] Currently, plastic film needs to be cut into pieces using a slitting machine during the processing.

[0004] The lithium battery film slitting machine frame disclosed in the prior art (CN222628017U) includes a support frame, a U-shaped scrap box fixed between two support frames, a first motor installed on the outer wall of one of the support frames, a pusher auger fixed inside the U-shaped scrap box on the output shaft of the first motor, and a discharge pipe fixed through the outer wall of the other support frame.

[0005] While this slitting machine allows for easy replacement of the slitting rollers, its slitting blades are typically fixed to the roller surface using welding or other methods, forming a single, integrated design. The drawback of this structure is that when the blades become dull or their cutting accuracy decreases due to prolonged use, the entire slitting roller must be disassembled and replaced, resulting in high maintenance costs. Furthermore, the spacing between the blades is a fixed parameter, which cannot be flexibly adjusted according to actual production needs (such as different film widths or slitting specifications), greatly limiting the equipment's applicability.

[0006] Therefore, improvements are proposed. Utility Model Content

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency slitting machine, comprising a slitting machine frame, a take-up roller installed inside the slitting machine frame, and a PLC controller installed on the outer wall of the slitting machine frame, wherein a guide roller assembly is installed inside the slitting machine frame;

[0009] Two electric lifting components are fixedly installed on the inner walls of both sides of the slitting machine frame. The four electric lifting components are arranged in pairs. In one pair, the two electric lifting components are rotatably connected to a first adjusting roller, and in the remaining pair, the two electric lifting components are rotatably connected to a second adjusting roller.

[0010] The slitting machine frame is equipped with a first electric spline and a second electric spline, and multiple rubber wheels are slidably sleeved on the outer surface of the first electric spline.

Both sides of the outer surfaces of the multiple mounting sleeves are provided with locking bolts that penetrate into the interior, and the locking bolts are threadedly connected to the mounting sleeves. Each of the multiple mounting sleeves is rotatably sleeved with a connecting plate together with an adjacent rubber wheel. Each of the multiple mounting sleeves is fixedly sleeved with a mounting plate. Each of the multiple mounting plates is provided with an assembly shaft that penetrates through it.

The drive end of the first motor is fixedly connected to a first spline shaft, which completely penetrates the slitting machine frame and is rotatably connected to it. Rubber wheels are slidably sleeved on the outer surface of the first spline shaft. The arrangement of the first spline shaft facilitates the synchronous driving of multiple rubber wheels.

[0014] Furthermore, the second electric spline includes a second motor, which is fixedly mounted on one side of the outer wall of the slitting machine frame. The drive end of the second motor is fixedly connected to a second spline shaft, which completely penetrates the slitting machine frame and is rotatably connected to it. The mounting sleeve is slidably fitted onto the outer surface of the second spline shaft, and the locking bolt abuts against the outer wall of the second spline shaft. The locking bolt facilitates the mounting sleeve to be squeezed and limited on the outer surface of the second spline shaft.

[0015] Furthermore, each of the aforementioned cutting tools includes a square base, which is inserted into and positioned on the assembly shaft. The square base and the assembly shaft are fixed together by connecting bolts. A tool holder is fixedly connected to one end of the square base, and an annular cutter is fixedly connected to the mounting end of the tool holder. The square base facilitates the tool's installation with the assembly shaft positioned on it.

[0016] Furthermore, the guide roller assembly includes a first guide roller, a second guide roller, and a third guide roller, and both ends of the first guide roller, the second guide roller, and the third guide roller are rotatably connected to the slitting machine frame, which can guide the film.

[0017] Furthermore, all of the assembly shafts are rotatably connected to adjacent mounting plates, and the mounting plates provide support for the assembly shafts, which facilitates their installation.

[0032] Multiple mounting sleeves 15 are slidably fitted onto the outer surfaces of multiple second electric splines. Each mounting sleeve 15 has a locking bolt 16 extending through to the interior on both sides of its outer surface, and the locking bolt 16 is threadedly connected to the mounting sleeve 15. The second electric spline includes a second motor 3, which is fixedly mounted on one side of the outer wall of the slitting machine frame 1. The drive end of the second motor 3 is fixedly connected to a second spline shaft 21, which completely penetrates the slitting machine frame 1 and is rotatably connected to it. The mounting sleeves 15 are slidably fitted onto the outer surface of the second spline shaft 21, and the locking bolts 16 abut against the outer wall of the second spline shaft 21.

These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that this hardware structure improvement can achieve in conjunction with common knowledge.

[0035] Working principle: Segmentation path (e.g.) Figure 4 As shown, the film enters the slitting machine frame 1 through the first guide roller 7, and then passes through the first adjusting roller 24, the second guide roller 23, the cutter, the second adjusting roller 4, the third guide roller 6 in sequence, and finally is wound up on the take-up roller 5.

[0036] Before using the equipment, loosen all the locking bolts 16 with a tool, then move the mounting sleeve 15, and adjust the position of the rubber wheel 20 and the cutter through the connecting plate 14 until the desired position is achieved. Then tighten the locking bolts 16.

[0037] When the equipment is running normally, the operator can insert the square base 18 of the new cutter into the limiting groove of the empty assembly shaft 11 in advance to ensure that the cutter base 17 and the annular cutter 13 are in the correct position. Then, use the connecting bolts 12 to fix the square base 18 to ensure that the cutter is installed firmly.

[0038] During tool changing, the second motor 3 starts, driving the second splined shaft 21 to rotate. This rotation, via the mounting sleeve 15, causes the mounting plate 10 to rotate synchronously, thereby adjusting the tool on the assembly shaft 11 to the working position. Simultaneously, the electric push rods 8 intelligently adjust: one set of electric push rods 8 raises the first adjusting roller 24 via the bearing seat 19, while the other set synchronously lowers the second adjusting roller 4, dynamically adjusting the film material's travel path and tension distribution. This coordinated action ensures that the film material maintains a stable cutting state during tool switching, achieving truly uninterrupted production.
