Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a telescopic arm winding device for a winding machine. Background Technology

[0002] Tank winding machines are mainly used to produce fiberglass storage tanks, pipes, and other products. They achieve rapid forming of anti-corrosion or protective layers through automated winding processes. The core of their operation lies in precisely controlling the fiber winding angle and tension to improve production efficiency and ensure quality. Existing winding machines' telescopic arm winding mechanisms generally suffer from the following defects:

[0003] (1) Poor vibration resistance of the winding arm: The integral bracket needs to be manufactured by mold, which is costly and easily deformed under high frequency operation;

[0004] (2) The telescopic arm has weak rigidity: the traditional sleeve structure is fixed only at the end, and radial swing occurs during the telescopic process;

[0005] (3) Insufficient structural stability: Existing telescopic arm winding devices for large tanks generally suffer from insufficient structural stability.

[0006] The present invention aims to solve the above-mentioned technical pain points and provide a telescopic arm winding device for a winding machine that is structurally stable, rigid, and highly vibration resistant. Summary of the Invention

Example 1

[0028] See Figures 1-7 , Figure 1 A schematic diagram of the structure of this utility model has been drawn. As shown in the figure, this utility model relates to a telescopic arm winding device for a winding machine, which includes a frame 1 and a winding assembly 2 disposed on the frame 1.

[0029] The frame 1 is a well-type frame 1, including four support columns 1.1. The top and bottom of two adjacent support columns 1.1 are connected by side crossbeams 1.2. The top and bottom of the two front support columns 1.1 are connected by front crossbeams 1.3. The top of the two rear support columns 1.1 are connected by a lifting motor mounting crossbeam 1.4. The middle of the lifting motor mounting crossbeam 1.4 is provided with a motor mounting seat 1.5 for mounting the lifting motor.

[0030] The lifting assembly includes a lifting platform, an adjustment platform, and a lifting motor. A support guide rail is provided on the inner side of each of the two support columns 1.1 of the lifting motor mounting beam 1.4. The lifting platform comprises a rectangular frame consisting of two sets of lifting beams and two sets of lifting side beams. Two parallel lifting center beams connect the two sets of lifting beams, and the lifting center beams are parallel to the lifting side beams. The left and right ends of one of the lifting beams are slidably mounted on the support guide rails of the two support columns 1.1 via sliders.

[0031] Two lifting beams are each equipped with a hot-rolled light rail. An adjustment platform slides on each hot-rolled light rail. A first ball screw and a second ball screw are arranged in parallel on the inner sides of the two hot-rolled light rails. The adjustment platform is driven by an adjustment motor, which is mounted on the lifting beam via an adjustment mounting base 1.5. The output end of the adjustment motor is connected to one end of the first ball screw. A synchronous pulley is provided at the other end of the first ball screw. Another synchronous pulley is provided at the same end of the second ball screw. A synchronous belt connects the two synchronous pulleys, so that the first ball screw and the second ball screw move synchronously. The ball nuts on the first ball screw and the second ball screw are respectively connected to the two ends of the adjustment platform.

[0032] A boom motor is located above the adjustment platform. The boom motor is connected to the top of the boom via a connecting shaft. The lower part of the connecting shaft is tapered and threadedly tightened to the top of the boom to avoid the use of a coupling, which is prone to detachment. The bottom end of the boom is connected to the tank to be wound via a rotatable fitting, allowing the tilt angle of the tank to be wound to be adjusted. A through hole is provided in the center of the adjustment platform for the boom to pass through the platform.

[0033] The outer side of the lifting beam is provided with a chain guide lug at one end near the lifting motor mounting beam 1.4, and a chain connecting lug at the other end.

[0034] On the left and right sides of the lifting motor mounting beam 1.4, sprocket assemblies are symmetrically arranged. Each sprocket assembly includes a lifting motor drive shaft assembly, a lifting active bearing assembly, a lifting passive bearing assembly, a drive wheel, a passive wheel, a first guide wheel, a second guide wheel, a long chain assembly, and a short chain assembly. The drive wheel is connected to the lifting motor drive shaft assembly through the lifting active bearing assembly, and the passive wheel is connected to the lifting passive bearing assembly. The lifting active bearing assembly and the lifting passive bearing assembly are respectively fixed on the side beam 1.2 at the top of the frame 1.

[0035] Below the drive wheel is a first guide wheel, which is located on the bottom surface of the side beam 1.2 below the lifting drive bearing assembly. The second guide wheel is located on the side beam 1.2 at the bottom of the frame 1. The drive wheel is connected to the driven wheel after passing around the first guide wheel via a long chain assembly. The long chain assembly is connected to the chain connecting lug of the lifting platform after passing around the driven wheel. The long chain assembly passes through the drive wheel and then goes around to the second guide wheel. The long chain assembly wound on the second guide wheel is connected to the first guide wheel via a short chain assembly. The short chain assembly passes through the chain guide lug of the lifting platform.

[0036] The lifting motor drive shaft assembly is connected to the lifting motor, and the lifting motor is mounted on the lifting motor mounting beam 1.4 via the motor mounting base 1.5;

[0037] This allows the lifting motor to drive the lifting motor drive shaft assemblies on both sides, which in turn drive the drive wheel, which in turn drives the driven wheel, thus enabling the lifting platform to move up and down.

[0038] In this embodiment, the existing inner chain is placed on the outer side to prevent chain interference.

[0039] The winding assembly 2 includes a winding arm fixing frame 2.1, a servo electric cylinder 2.2, a winding angle adjustment motor 2.3, a slewing bearing 2.4, a cylindrical gear 2.5, a winding arm bracket 2.6, a telescopic arm connector 2.7, a telescopic arm 2.8, and an arm extension servo drive assembly 2.9;

[0040] Below the top crossbeam 1.3 of the frame 1, a winding arm fixing frame 2.1 is provided. The winding arm fixing frame 2.1 is located between two left and right support columns 1.1. The winding arm fixing frame 2.1 is equipped with a servo electric cylinder 2.2 and a winding angle adjustment motor 2.3. The output end of the servo electric cylinder 2.2 is connected to a slewing bearing 2.4. The slewing bearing 2.4 meshes with a cylindrical gear 2.5. The slewing bearing 2.4 is connected to a telescopic arm connector 2.7. Two telescopic arms 2.8 are symmetrically connected to the left and right sides of the telescopic arm connector 2.7. An arm extension servo drive assembly 2.9 is provided between the two telescopic arms 2.8. The arm extension servo drive assembly 2.9 is used to drive the extension and retraction of the telescopic arms 2.8.

[0041] The servo cylinder 2.2 is also externally equipped with a winding arm bracket 2.6 to increase stability. The winding arm bracket 2.6 is connected and fixed to the servo cylinder 2.2 by a clamp. The bottom of the winding arm bracket 2.6 is hinged to the winding arm fixing frame 2.1 by a hydraulic cylinder mounting accessory and a bearing. The output end of the winding angle adjustment motor 2.3 is hinged to the servo cylinder 2.2 by a connector, so that the winding angle adjustment motor 2.3 drives the servo cylinder 2.2 to adjust, thereby driving the telescopic arm 2.8 to adjust the tilt angle. The winding angle adjustment motor 2.3 is connected to a reducer.

[0042] In this embodiment, the telescopic arm 2.8 is made of seamless steel pipe with inner and outer sleeves: an inner tube and an outer tube. The outer tube is fixed with only six screws around its circumference to prevent shaking.
