Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a machine head structure that facilitates the disassembly and assembly of the slitting cutter shaft. Background Technology

[0002] A slitting machine is a mechanical device specifically designed to cut wide-width paper, mica tape, or film into multiple narrow strips. It plays an important role in many industries, especially in papermaking, wire and cable manufacturing, and printing and packaging. The main feature of this equipment is its efficient and precise cutting of materials into the required specifications to meet different production needs. It is widely used in the processing of non-woven fabrics, mica tape, various types of paper, lithium battery coating, insulating materials, and film materials. Its design is particularly suitable for processing narrow strip materials, thus achieving higher output and utilization rates during production. Slitting machines are usually equipped with advanced cutting tool systems, which achieve precise cutting by adjusting the cutting pressure and speed, ensuring smooth edges of the cut materials and reducing unnecessary waste.

[0003] Existing slitting machines typically use a cutter shaft to slit materials. To facilitate adjustment of the cutter shaft's position, both ends of the cutter shaft are connected to the machine frame in an adjustable manner. For example, Chinese Patent Publication No. CN221936943U discloses a "cutter shaft positioning mechanism for a lithium battery aluminum foil slitting machine," which connects two bearing seats on the machine headstock into a single structure. One of the bearing seats on the machine headstock is mounted on a mounting plate and slidably connected to a support plate. A lead screw is installed on the support plate and connected to the mounting plate. By selecting the position of the mounting plate on the support plate through the lead screw, the position of the bearing seat can be moved, thereby facilitating the adjustment of the cutter shaft's level. Using this positioning mechanism enables rapid adjustment of the cutter shaft's level, effectively reducing the operator's labor intensity and improving production efficiency.

[0004] However, in actual use, the cutter shaft of the slitting machine needs to be replaced or repaired after long-term use, which requires disassembling the entire machine head or performing complex operations, increasing maintenance time and costs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need to replace or repair the cutter shaft of a slitting machine after long-term use, requiring the disassembly of the entire machine head or complex operations, which increases maintenance time and costs. This invention proposes a machine head structure that facilitates the disassembly and assembly of the slitting cutter shaft.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a machine head structure that facilitates the disassembly and assembly of the slitting cutter shaft, including support columns and a connecting seat for hydraulically connecting the cutter shaft. A sliding groove is formed between the two support columns, and the connecting seat is slidably disposed in the sliding groove. Limiting structures that cooperate with the support columns are provided on both sides of the connecting seat.

[0008] The limiting structure includes a fixed plate and a movable plate. The fixed plate and the movable plate are respectively disposed on both sides of the support column. The fixed plate is fixedly connected to the connecting seat. The connecting seat has a slot. The movable plate is fixedly disposed with a plug that cooperates with the slot.

[0009] Furthermore, the connector is provided with a positioning component that cooperates with the insert block, and the connector is also provided with a receiving groove that cooperates with the positioning component.

[0010] Furthermore, the positioning component includes a positioning block slidably disposed within the receiving groove, a positioning post fixedly disposed on the positioning block, and a through groove corresponding to the positioning post being provided on the receiving groove.

[0011] Furthermore, a spring is provided on one side of the positioning block, and the spring abuts against the receiving groove.

[0012] Furthermore, the connecting seat is provided with a positioning groove, and a limiting block corresponding to the slot is slidably disposed in the positioning groove, and the limiting block is fixedly connected to the positioning block.

[0013] Furthermore, the movable plate is provided with mounting holes, the positioning post is provided with threaded holes, and a bolt is provided in the mounting holes. The bolt passes through the insert block and is threadedly connected to the positioning post.

[0014] The present invention proposes a machine head structure that facilitates the disassembly and assembly of the slitting cutter shaft, the advantages of which are:

[0015] In this utility model, by setting limiting structures on both sides of the connecting seat, the connecting seat is fixed so that it will not separate from the slide groove when it moves up and down to adjust its position, thus preventing the cutter shaft from falling off during use.

[0016] Secondly, in this utility model, the limiting structure includes a fixed plate and a movable plate. When replacing the cutter shaft, the movable plate can be removed to disassemble the connecting seat, making it convenient to take out the cutter shaft for maintenance and replacement.
