Description

1 TARIFF FIBER HAUL OFF DEVICE TECHNICAL FIELD The invention relates to the production of fibers in pultrusion, fiber-reinforced filament and / or composite production lines. It relates to a low-cost fiber pulling device that performs the orientation. PREVIOUS TECHNIQUE Today, composites are used primarily in the aerospace industry, as well as in the automotive sector. It is increasingly used in transportation and medical sectors. (Owner 10) Thanks to their high strength and low weight, they are an alternative to metals. On the other hand, due to production costs, their areas of use are limited. It is restricted. There are multiple methods for producing composite materials. However, this production... Fiber handling is crucial in these methods. Fibers are generally processed in 15 Although they possess quite high mechanical properties in the normal direction, shear It can be easily damaged under these forces. For this reason, during production... It should be controlled as carefully as possible, should not be touched, and Precise equipment must be used during the haul-off process. The devices also comply with these rules, especially in pultrusion lines, by drawing the fibers to 20 It ensures the direction of movement. However, there is a point or linear pull on the fiber. If the required force is applied, it is obvious that the fiber will be damaged. For this reason, Haul- Off-road devices use belts made of special materials to create a track system. It is being installed and the force is transmitted by these belts. The belt and track Due to the position of the rollers and the precision of the forces they apply, 25 Haul-off devices require an investment in the millions of dollars, depending on their application. is happening. THE PURPOSE OF THE INVENTION Haul-off devices utilize a wide belt length and distributed load of 30 for pulling the fiber. It uses a pallet system to create this. It applies force precisely. The position and adjustment of each shaft are crucial for the application and for pulling without damaging the fiber. It needs to be perfect. The main purpose of our invention is to fit into a very small space. It provides a long contact angle and enables highly precise pulling. 2 The goal is to establish a fiber drawing system. The results obtained for this purpose... The technical effects can be listed as follows: - The cost has been significantly reduced. - The length of the fiber production line has been significantly shortened. - The load applied to the highly sensitive fiber is easily transferred via a mechanism of 5 It is adjustable.

Adjustable Guiding Roller DETAILED DESCRIPTION OF THE INVENTION 20 The invention is a fiber haul-off apparatus through which a fiber (1) can pass; guide roller (2), belt (3), fiber pulling pulley (4), motor (5) and adjustable The guiding roller consists of (6) parts. The production starts by compressing the fiber (1) between the pulley (4) and the belt (3). Gluing, coating, drying, polymer 25 before or after the fiber (1) drawing zone It can be subjected to various treatments such as feeding. Within the scope of the invention The fiber to be used (1) is of the desired fiber size (1K, 3K, 12K etc.) and the desired fiber type. Materials can include carbon, glass, Kevlar, natural materials, etc. Belt (3), guide roller (2) and adjustable guide roller (6) It winds around the pulley (4) by passing through it. As the pulley (4) rotates, the belt 30 (3) also rotates. The rotational movement is provided by the motor (5). Motor (5), It can be an electric, stepper, servo, or any type of motor. The belt is moved forward or backward by moving the adjustable guide roller (6). (3) increases the stress value on the fiber. With this increase in stress value, the fiber 3 (1) the necessary tensile force between the belt (3) and the pulley (4) without damaging the fiber (1). A friction force is generated that can be given. Belt (3) and pulley (4) contact angles The force value and fiber (1) orientation can be achieved by increasing or decreasing it. Increased contact angle results in higher friction on the fiber / filament. This is done in such a way that the tension / load ratio on the fiber is 5. By adjusting the settings, pulling can be performed without damaging the fibers. Furthermore, the invention... By using multiple units in succession, the fiber direction can be adjusted as desired. Normally, fiber drawing lines need to be long. In this case, a large workshop is required. This area is needed. Thanks to this system, the fiber can be given direction and angle. In this way, the production line can be routed appropriately within the workshop, saving space. can be provided. 20 30
