Abstract
Description
Technical Field
[0001] This utility model belongs to the field of needle cutting technology, specifically, it relates to a multi-functional cutting device for needle production. Background Technology
[0002] Needle-punched nonwoven fabric is a type of nonwoven fabric. It utilizes needles with triangular (or other cross-sections) and barbed edges to repeatedly pierce a fiber web. As the barbs penetrate the web, they force the surface and some inner layers of fibers into the web. Due to friction between the fibers, the originally loose web is compressed. When the needle withdraws from the web, the inserted fiber bundles detach from the barbs and remain in the web. This causes many fiber bundles to become entangled, preventing the web from returning to its original loose state. After many needle-punching cycles, a considerable number of fiber bundles are penetrated into the web, causing the fibers to become entangled, thus forming a needle-punched nonwoven material with a certain strength and thickness.
[0003] In the production of needle-punched nonwoven fabric, nonwoven needles are an essential tool. During the processing of nonwoven needles, the steel wires used to make needles need to be cut into sections. After the cut steel wires are sorted, they are then processed by the machine to the next step. In the existing technology, the steel wires are usually wound on a coil frame. The wires are cut by pulling one end. This method has certain drawbacks. First, the steel wires need to be straightened before cutting. Most existing solutions achieve this by passing the steel wires through the inside of the roller. This method has a relatively poor straightening effect. In addition, the end-pulling method requires frequent connection and disconnection of the traction mechanism from the traction end of the steel wire, which is inconvenient and inefficient.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.
[0005] Therefore, in order to solve the above problems, this utility model provides a multi-functional cutting device for needle production. Utility Model Content
[0006] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a multi-functional cutting device for needle production. The device draws the steel wire into the arc-shaped groove, passes it under the first and second straightening rollers, and passes it through the guiding mechanism. The guiding mechanism draws and transports the steel wire. When the steel wire moves to the bottom of the cutting component, the cutting component cuts the steel wire. The cut steel wire segments fall onto the conveyor belt and are then transported away by the conveyor belt.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] A multifunctional cutting device for needle production includes a frame with an arc-shaped groove at the top for accommodating steel wire. A straightening assembly for straightening the steel wire is mounted at the top of the frame, comprising two sets of rotatable first and second straightening rollers. A guide mechanism for conveying the steel wire is also mounted at the top of the frame. A cutting assembly for cutting the steel wire is also mounted on the frame. A conveyor belt for conveying the cut steel wire is also provided on the frame. The steel wire is drawn into the arc-shaped groove, passes under the first and second straightening rollers, and passes through the guide mechanism. The guide mechanism pulls and conveys the steel wire. When the steel wire reaches the cutting assembly, the cutting assembly cuts the wire, and the cut wire segments fall onto the conveyor belt and are then transported away.
[0009] Furthermore, a tray for holding steel wire is installed at the top of the frame.
[0010] Furthermore, the straightening assembly also includes a first mounting bracket, a second mounting bracket, and a motor base fixedly installed on the top of the frame. A first straightening roller is rotatably connected to the first mounting bracket, and a first rotating rod is connected to one end of the first straightening roller. A first sprocket is fixedly installed on the first rotating rod. A second straightening roller is rotatably connected to the second mounting bracket, and a second rotating rod is connected to one end of the second straightening roller. A second sprocket is fixedly installed on the second rotating rod. The first sprocket and the second sprocket are connected by a chain drive. A motor is fixedly installed on the top of the motor base, and the output end of the motor is connected to one end of the first rotating rod.
[0011] Furthermore, the guiding mechanism includes two sets of vertically arranged conveying rollers, which rotate synchronously in opposite directions via a driving mechanism.
[0012] Furthermore, the cutting assembly includes a third mounting bracket fixedly installed at the top of the frame, a hydraulic rod is mounted on the third mounting bracket, a tool holder is mounted at the output end of the hydraulic rod, and a cutting tool is mounted at the bottom end of the tool holder.
[0013] Furthermore, the top of the frame is provided with a top groove, and a conveyor belt is installed inside the top groove.
[0014] Furthermore, a bracket is fixedly installed at the bottom of the frame.
[0015] Furthermore, a cutting groove is provided at the top of the frame, and the position of the cutting groove corresponds to the position of the cutting tool.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, a steel wire is drawn from the reel and passes under the first and second straightening rollers, between two sets of conveying rollers on the guiding mechanism. The steel wire is pulled and conveyed by the two sets of conveying rollers rotating in opposite directions. A motor drives the first rotating rod to rotate, which in turn drives the first straightening roller to rotate. Simultaneously, the first rotating rod drives the first sprocket to rotate, which in turn drives the second rotating rod to rotate via a chain. The second rotating rod drives the second straightening roller to rotate. The rotation of the first and second straightening rollers straightens the steel wire. When the steel wire moves to the bottom of the cutting assembly, a hydraulic rod drives the cutting tool to descend. The descending cutting tool cuts the steel wire, and the cut steel wire segments fall onto the conveyor belt and are then transported away by the conveyor belt. Attached Figure Description
