Description

Technical Field

[0001] This utility model relates to the technical field of steaming machine components, specifically a magnetic levitation chainless long ring steaming machine guide ring structure. Background Technology

[0002] The traditional long-ring steaming machine's guide transmission system mainly consists of a "chain drive unit + needle plate / cloth clip traction assembly," employing a double-row roller chain structure. The chain pitch is typically 25-50mm, and each chain link is composed of alloy steel chain plates, pins, and rollers. A motor drives the drive sprocket, causing the chain to circulate along the upper and lower circular tracks of the steaming machine. The chain tension is controlled by an adjustable tension wheel at the tail. The needle plates are fixed to the outer side of each chain link with bolts, and guide needles are evenly distributed on the surface of the needle plates. The cloth clips are fixed to the fabric edge by a spring clamping mechanism. The circulating movement of the chain drives the fabric to complete the steaming process.

[0003] However, under long-term high temperature and heavy load conditions, the wear between the chain plate and the pin will cause the chain elongation to accumulate gradually, which can easily lead to chain skipping and running jams, resulting in uneven fabric tension, wrinkles or stretching deformation. It is necessary to stop the machine regularly to adjust the tension, which affects the continuity of production. In order to reduce chain wear, high temperature lubricating oil needs to be added to the chain pin regularly. However, in the high temperature environment of the steaming machine, the lubricating oil is easy to evaporate and form oil mist, or drip due to chain vibration, which contaminates the fabric surface. Especially for light-colored, high-count and high-density fabrics, the oil stains are difficult to remove. Utility Model Content

[0004] The purpose of this invention is to provide a guide ring structure for a magnetically levitated chainless long-ring steamer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide ring structure for a magnetically levitated chainless long-ring steamer, comprising a magnetically levitated drive, a guide ring body, an electromagnetic drive coil, a mounting frame, a fastening bolt, and a fixing frame. The guide ring body is installed inside the magnetically levitated drive, the electromagnetic drive coil is located on the back of the magnetically levitated drive, the mounting frame is installed at one end of the guide ring body, the fastening bolt is located inside the mounting frame, and the fixing frame is installed on the outside of the magnetically levitated drive.

[0006] The magnetic levitation drive includes a track body, a U-shaped groove, and a permanent magnet array. The U-shaped groove is formed inside the track body, and the permanent magnet array is disposed inside the U-shaped groove.

[0007] The guide ring body includes a circular frame, a soft magnetic stainless steel strip, a connecting plate, and a rotating block. The soft magnetic stainless steel strip is disposed on the outside of the circular frame, the connecting plate is fixedly connected to the inside of the circular frame, and the rotating block is fixedly connected to the other end of the connecting plate. When the electromagnetic drive coil is energized to generate a traveling wave magnetic field, the soft magnetic stainless steel strip induces an eddy current magnetic field, which interacts with the traveling wave magnetic field to form a non-contact propulsion force, driving the guide ring body to levitate and run along the inside of the track body.

[0008] Preferably, the fixing frame includes a connecting block, a mounting rod, a fixing hole, and a movable groove. The connecting block is fixedly connected to the outside of the track body, the mounting rod is installed at one end of the connecting block, the fixing hole is opened at one end inside the mounting rod, and the movable groove is opened at the other end inside the mounting rod. The design of the fixing hole and the movable groove makes it easier to install the equipment in the steaming machine, reduces the installation difficulty, and improves the efficiency of disassembly and replacement.

[0009] Preferably, air floats are evenly installed on both sides of the U-shaped groove. The surface of the air floats is provided with micro air jet holes. The air floats are connected to a high-pressure air source through air pipes. When the magnetic levitation drive and the guide ring body are running, the air floats spray high-pressure airflow to form an air film between the magnetic levitation drive and the guide ring body, thereby achieving radial limiting, avoiding left and right deviation during operation, and eliminating mechanical friction.

[0010] Preferably, the permanent magnet array consists of neodymium iron boron permanent magnets embedded in a U-shaped groove along the circumferential direction. The permanent magnets have a fan-shaped structure, with the magnetic poles of each permanent magnet arranged radially alternately. The spacing between adjacent permanent magnets is 5-8 mm, forming a continuous radial magnetic field.

[0011] Preferably, the size of the electromagnetic drive coil is the same as the size of the track body. The coil uses high-temperature resistant copper enameled wire and multiple sets of coils are set. Each set of coils is powered by a programmable controller to form a traveling wave magnetic field that moves along the circumference of the track.

[0012] Preferably, the track body is made of lightweight aerospace aluminum alloy to form a ring frame, which is lighter than traditional chains.

[0013] Preferably, the soft magnetic stainless steel strip is polished and the gap between it and the permanent magnet array inside the track is controlled at 2-3mm to ensure stable operation.

[0014] Preferably, a Hall sensor is installed inside the track body to detect the gap between the track and the permanent magnet array in real time. The data is fed back to the PLC, and the current intensity of the electromagnetic drive coil is adjusted to ensure the stability of the suspension gap.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The magnetic levitation chainless long ring steamer has a guide ring structure, non-contact drive and air flotation limit, no mechanical wear, extended service life of the guide ring, reduced maintenance costs, low frictional resistance during use, and reduced motor energy consumption.

[0016] 2. The magnetic levitation chainless long ring steaming machine has a guide ring structure that completely eliminates the chain, solving the problems of chain elongation and oil shedding, and improving the fabric qualification rate. Attached Figure Description

Air floats are evenly installed on both sides of the U-shaped groove 102. The surface of the air floats has micro-jet holes. The air floats are connected to a high-pressure air source through air pipes. When the magnetic levitation drive 1 and the guide ring body 2 are running, the air floats eject high-pressure airflow, forming an air film between the magnetic levitation drive 1 and the guide ring body 2, achieving radial limiting and preventing lateral deviation during operation. To eliminate mechanical friction, the permanent magnet array 103 consists of neodymium iron boron permanent magnets embedded in the U-shaped groove 102 along the circumferential direction. The permanent magnets have a fan-shaped structure, with the magnetic poles of each permanent magnet arranged radially alternately. The spacing between adjacent permanent magnets is 5-8mm, forming a continuous radial magnetic field. The track body 101 is made of lightweight aerospace aluminum alloy to form a ring frame, which is lighter than traditional chains.
