Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber chopped short-cut equipment, and specifically relates to an offset transition yarn guide mechanism of an automatic head-up continuous online short-cutting machine. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and comes in many varieties. It is characterized by heat resistance, corrosion resistance, good insulation properties and high mechanical strength. It is usually used as a reinforcing material in composite materials and is widely used in national economic fields such as aerospace, transportation, mechanical electronics, and building materials.

[0003] The glass fiber manufacturing process is briefly described as follows: ore raw materials are formulated and melted in a kiln to form molten glass. The glass then flows through a porous platinum bushing, where it is coated with a sizing agent by a monofilament oiler. The glass is then drawn into ultrafine fibers by various high-speed drawing equipment, such as a wire drawing machine, or processed into chopped strands by a chopper. The bushing, oiler, and bunching wheel are all existing equipment in the industry.

[0004] One of the purposes of chopping is to cut glass fiber yarn into suitable sizes for processing into desired products. For example, the chopped glass fiber yarn segments can be added to cloth or sheet material and then made into glass fiber cloth or glass fiber sheet through adhesives and other raw materials. A chopper is a special equipment used to complete glass fiber chopping. The chopper unit is generally equipped with a rubber roller and a knife roller. The rubber roller and knife roller cooperate to achieve continuous chopping of glass fibers. Continuous chopping machines are generally equipped with a unit turntable and two chopping units. The two chopping units are replaced by rotating the unit turntable to achieve continuous chopping production and to perform maintenance on damaged chopping units.

[0005] For current short-cut equipment, please refer to:

[0006] Chinese patent: A single-sided double-knife roller automatic quick-change online high-speed glass fiber chopping machine, patent number CN202011007628.6.

[0007] Chinese patent: A single-sided automatic reversing continuous online glass fiber chopping machine, patent number CN202011417133.0.

[0008] The existing problem is that since one short-cutting machine is often responsible for the short-cutting of glass fiber yarns of multiple bushings, the yarn leading work of the newly added bushing will affect the continuous production of the bushings that have completed the yarn leading and are in normal production.

[0030] See also Figure 1 The offset transition yarn guide mechanism provided in this application is used in the pulling and short-cutting process of glass fiber yarn. It is responsible for pulling the glass fiber yarn from the leak plate and after oiling and bundling to a position deviating from the normal short-cut yarn line, and then the yarn is pulled up by the yarn-leading robot.

[0031] See also Figure 2 The offset transition yarn guide mechanism provided in this application includes a fixed plate 10, an offset plate 20, and an offset transition yarn guide wheel 30.

[0032] A connecting member 40 is provided on the fixing plate 10 , and the connecting member 40 is used to install the offset transition yarn guide mechanism to the infrastructure (in this embodiment, the column carrying the oiler and the bunching wheel).

[0033] The offset plate 20 includes a primary offset plate 210, a secondary offset plate 220, and a guide wheel mounting frame 230; the secondary offset plate 220 includes a sliding fitting portion 2210 and a guide wheel assembly portion 2220, and the extension directions of the sliding fitting portion 2210 and the guide wheel assembly portion 2220 are perpendicular to each other.

[0034] The primary offset plate 210 is slidably connected to the fixed plate 10 through a guide rail pair, and the sliding matching part 2210 of the secondary offset plate 220 is slidably connected to the primary offset plate 210 through a guide rail pair; the guide wheel mounting frame 230 is fixedly assembled on the guide wheel assembly part 2220 of the secondary offset plate 220.

[0035] The offset transition yarn guide wheel 30 includes two same-direction yarn guide wheels 310 and two reversing yarn guide wheels 320. The reversing yarn guide wheels 320 are arranged below the same-direction yarn guide wheels 310.

[0036] The same-direction yarn guide wheel 310 and the changing yarn guide wheel 320 are both arranged on the yarn guide wheel assembly portion 2220 , and the yarn guiding direction of the changing yarn guide wheel 320 is perpendicular to the yarn guiding direction of the same-direction yarn guide wheel 310 .

[0037] The same-direction yarn guide wheel 310 is used to receive the yarn from the bunching wheel, and the reversing yarn guide wheel 320 is used to adjust the direction of the yarn from the same-direction yarn guide wheel 310 so that the yarn can be pulled by the yarn guiding robot to the end yarn of the short cutting machine.

[0038] Principle and effect description:

[0039] When a new leak plate needs to be added to the short-cutting process, the relative movement between the offset plate and the fixed plate is achieved through manual operation or motor drive, and the offset transition yarn guide wheel is positioned to a suitable position deviating from the normal short-cutting yarn path, and then the yarn-leading robot pulls the yarn to the short-cutting machine to load the yarn. After the yarn is loaded, the offset transition yarn guide wheel is positioned to the normal short-cutting yarn path for short-cutting processing. Therefore, by arranging an offset transition yarn guide mechanism under the leak plate, the present application can pull the yarn from the bunching wheel under the leak plate to the positions on both sides of the yarn path deviating from the normal short-cutting yarn path for yarn loading, thereby avoiding affecting the normal short-cutting work.
