Description
Technical Field
[0001] The utility model relates to the technical field of slitting machine equipment, in particular to a knife arrangement structure which is convenient for accurately adjusting the knife distance. Background Art
[0002] A slitter is a machine used to slit wide rolls of material, such as film, paper, and foil, into multiple narrow strips. Slittering is crucial in the film production process, enabling it to slit large rolls into smaller rolls of varying widths for subsequent processing and use. The working principle of a slitter typically involves a set of blades, which can be fixed or adjustable to accommodate varying slitting widths.
[0003] In the film processing industry, the performance of slitting machines directly impacts product quality and production efficiency. However, existing slitting machines present operational difficulties. In particular, when adjusting blade spacing, operators must individually adjust each blade to ensure accurate slitting. This process is not only time-consuming and labor-intensive, but also requires the use of measuring tools to ensure consistent spacing between each blade, which undoubtedly increases the difficulty and complexity of blade spacing adjustment.
[0004] Furthermore, existing slitting machines often require cumbersome disassembly and installation procedures when blades need replacing. Blade replacement not only requires specialized technicians, but improper operation can also lead to equipment damage or production accidents. These issues not only reduce production efficiency but also increase operating costs.
[0005] In response to the above problems, it is urgent to carry out innovative design based on the original slitting machine. Utility Model Content
[0006] The technical solution of the present invention aims to solve the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technology and has a knife arrangement structure that is convenient for accurately adjusting the knife spacing, so as to solve the problems raised in the above background technology.
[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a knife arrangement structure that is convenient for precise adjustment of the knife distance, comprising a frame, the frame is provided with an auxiliary roller for cooperating with slitting, and the frame is rotatably connected to a winding roller for winding, the frame is installed with a cylinder, and the cylinder is provided with an adjustment structure for adjusting the knife distance, the adjustment structure is connected to a mounting structure, and the mounting structure is connected to a blade.
[0008] Preferably, the cylinder is configured as a hollow structure, and the inner wall of the cylinder is engaged and limitedly connected with the adjustment structure, and the outer wall of the cylinder is provided with scale values.
[0009] Preferably, the adjustment structure includes a bidirectional threaded shaft and a sliding sleeve. The bidirectional threaded shaft is rotatably connected inside the cylinder, and a number of sliding sleeves are evenly spaced on the outer wall of the bidirectional threaded shaft, and each end of the sliding sleeve passes through the outer wall of the cylinder and is connected to a corresponding mounting structure.
[0010] Preferably, the thread pitch of the bidirectional threaded shaft decreases from tight to sparse from the middle to both ends, and the bidirectional threaded shaft and the sliding sleeve are threadedly connected.
[0011] Preferably, the mounting structure includes a fixed seat, a height adjustment screw, a movable seat, a control rotating rod, a full gear, a double gear rod, a gear block cylinder, an extrusion rod, and a knife groove. The end of the sliding sleeve is connected to a fixed seat, and the fixed seat is attached to the outer wall of the cylinder. The fixed seat is rotatably connected to the height adjustment screw and the limit rod, and the height adjustment screw and the limit rod are connected to the movable seat. The two end surfaces inside the movable seat are rotatably connected to the control rotating rod, and the control rotating rod is located in the outer wall of the movable seat and is connected to the full gear. The outer side of the full gear is meshed with a double gear rod, and the other end of the double gear rod is meshed with a gear block cylinder. The gear block cylinder is rotatably connected to one side of the inner wall of the movable seat, and the gear block cylinder is connected to the extrusion rod. The end of the extrusion rod is located in the knife groove, and the knife groove is opened at the end of the movable seat.
[0012] Preferably, the movable seat is configured as a "convex" hollow structure, and the knife groove is opened at the convex end of the movable seat.
[0013] Preferably, tooth blocks are provided at both ends of the double-toothed rod, and the tooth blocks at both ends of the double-toothed rod are not staggered on the same end surface.
[0014] Compared with the prior art, the beneficial effects of the present invention are: the blade arrangement structure is convenient for precise adjustment of the blade spacing, and when the blade spacing needs to be adjusted, the precise coordination of key parts such as the cylinder and the adjustment structure enables synchronous adjustment of the blade spacing. The core of this mechanism lies in the unique design of the two-way threaded shaft, whose threads change from tight to sparse from the middle to the two ends. When the blade spacing needs to be reduced, the threaded shaft enables the sleeves to maintain a consistent moving speed and distance as they approach each other, ensuring the uniformity of the spacing between the blades. Similarly, when the blade spacing needs to be increased, the sleeves on the threaded shaft also maintain precise spacing control as they move away from each other. This design cleverly utilizes the physical properties of the thread to achieve simultaneous and synchronous adjustment of the spacing between multiple blades.
[0015] Furthermore, this adjustment mechanism offers the advantages of convenience and efficiency. Operators no longer need to manually adjust each blade individually, nor do they need additional measuring tools for repeated calibration. This process not only significantly saves time and labor, but also improves adjustment accuracy and productivity.
[0016] By setting up the mounting structure, the blade can be fixed in a limited position without the aid of additional tools, bolts and other components, eliminating the tedious process of installing and disassembling the blade, making the fixing of the blade quick and easy, and significantly improving the installation efficiency.
