Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass production equipment, and more specifically, to a fiber tow output system. Background Technology

[0002] Fiberglass is a plastic-based composite material made of glass fiber and resin. It has advantages such as high strength and good bending and shear resistance, so it is often produced into profiles of various shapes and widely used in construction, transportation, environmental protection and other fields.

[0003] Glass fiber initially forms filament rolls and undergoes a series of processes, including fiber extrusion, resin coating, hot extrusion, cooling, and slitting, before it can be used to produce fiberglass profiles. Fiber extrusion is the first step in the production process, which refers to outputting glass fiber bundles at a reasonable rate and in an orderly manner. The fiber extrusion process is crucial to the smooth progress of subsequent production steps. Therefore, designing and applying a reasonably structured fiber bundle output system is an urgent need for enterprises, and this case arises from this need. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fiber bundle output system. This invention achieves orderly separation and output of glass fiber bundles by designing a fiber sorting plate, and detects and judges the rate deviation in production by installing a rate detection frame. When the deviation exceeds the standard, the deviation can be smoothed out by adjusting the fiber output speed of the fiber output device, thus realizing the need for rational adjustment of the fiber output speed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A yarn output system includes a raw yarn frame and a yarn guide frame. The raw yarn frame contains a plurality of yarn rolls, and a yarn output device is installed on the side of the raw yarn frame. The yarn bundles of all the yarn rolls are guided to the yarn output device for synchronous yarn output. A yarn guide plate is installed on the yarn guide frame, and a yarn path is formed between the yarn output device and the yarn guide plate. The yarn bundles are output after passing through the yarn guide plate. A speed detection frame is installed between the raw yarn frame and the yarn guide frame, and the yarn bundles pass through the speed detection frame.

[0007] Furthermore, the filament board has several through holes with spacing between adjacent through holes, and each through hole can only accommodate a single filament bundle.

[0008] Furthermore, the raw yarn frame, the rate detection frame, and the yarn sorting frame are arranged in a straight line.

[0009] Furthermore, an upper detection element and a lower detection element are installed inside the rate detection frame. The upper detection element is located directly above the lower detection element, and a filament passage space is formed between the upper detection element and the lower detection element.

[0010] Furthermore, the installation height of the filament outputter and the filament sorting plate is higher than that of the upper detection element, and the filament bundle forms a V-shaped motion trajectory between the upper and lower detection elements.

[0011] Furthermore, the wire-arranging frame includes an H-shaped frame and two insert plate seats. The two insert plate seats are symmetrically installed on the inner side of the H-shaped frame. The insert plate seats have vertical grooves that run vertically through the frame. One side of the vertical groove is open. The width of the vertical groove matches the thickness of the wire-arranging plate. The wire-arranging plate can be inserted into the two insert plate seats. The left and right sides of the wire-arranging plate are connected to positioning stops. The two positioning stops are symmetrically arranged and can rest on the insert plate seats.

[0012] Furthermore, the lower detection element is a horizontally mounted sensing plate.

[0013] Furthermore, the upper detection element includes two symmetrically mounted triangular supports, with two sensing rollers installed between the two triangular supports, and the two sensing rollers are symmetrically arranged on both sides of the filament bundle in and out direction.

[0014] The beneficial effects of this utility model are:

[0015] This invention features a fiber sorting plate, which allows glass fiber bundles to be orderly separated and output after passing through the fiber sorting plate, ensuring proper coordination with subsequent grease application. A speed detection frame is installed between the raw fiber frame and the fiber sorting frame. This frame can detect and determine the speed deviation during production based on the fiber sag. When the deviation exceeds the standard, the fiber output speed can be adjusted to smooth out the deviation, thus achieving a rational adjustment of the fiber output speed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 The illustrated fiber tow output system includes a raw fiber frame 1 and a fiber sorting frame 3. Fiberglass tow is one of the raw materials for producing fiberglass profiles. For ease of storage and transportation, the purchased fiberglass tow is in roll form. The raw fiber frame 1 is used to install the fiberglass rolls 11 required for production. A fiber ejector 2 is installed on the side of the raw fiber frame 1, from which one fiber tow is drawn out from each roll 11. All the fiber tows from the rolls 11 are guided to the fiber ejector 2 for synchronous output. The fiber ejector 2 functions similarly to a roller in textiles, actively pulling out the fiber tow. A fiber sorting plate 31 is installed on the fiber sorting frame 3, forming a fiber path between the fiber ejector 2 and the fiber sorting plate 31. The fiber tow passes through the fiber sorting plate 31 before being output. The fiber sorting plate 31 can organize the fiber tow, allowing it to be output in an orderly manner to meet the needs of subsequent resin coating operations. In the production process of fiberglass profiles, the movement of the fiber tow is driven by two factors: the output power at the fiber ejector 2 and the mold. The pulling force during the extrusion of the end profile, with two forces forming a push-pull effect, meets the needs of the filament bundle's movement. Ideally, the pulling speed of the filament bundle needs to be consistent with the filament output speed of the filament feeder 2 to ensure stable filament feeding. However, in reality, there will be a certain error between the two speeds. Accumulated errors will cause a large speed deviation. If the filament output speed of the filament feeder 2 is less than the pulling speed of the filament bundle, the filament bundle will be broken, affecting production. If the filament output speed of the filament feeder 2 is consistently greater than the pulling speed of the filament bundle, the filament bundle will gradually droop and drag on the ground, causing contamination on the surface of the filament bundle. Neither of these situations is acceptable. Therefore, this utility model installs a speed detection frame 4 between the original filament frame 1 and the filament sorting frame 3. The filament bundle passes through the speed detection frame 4, and the speed detection frame 4 detects and judges the speed deviation during production. When the deviation exceeds the standard, the deviation can be smoothed out by adjusting the filament output speed of the filament feeder 2, thus achieving the need for reasonable adjustment of the filament output speed.

[0023] like Figure 3As shown, the wire arrangement plate 31 has several wire passage holes 311, with spacing between adjacent wire passage holes 311. Each wire passage hole 311 can only accommodate a single wire bundle. The wire arrangement plate 31 is designed to solve the problem of orderly arrangement of wire bundles during output. Without the wire arrangement plate 31, the output wire bundles may clump together. Clumped wire bundles entering the coating tank will cause unstable coating quality. Only when the wire bundles are output in an orderly and separated manner can the outer surface of the wire bundles be fully exposed. Only when the outer surface of the wire bundles is fully exposed can a uniform and stable coating be formed in the coating tank. In actual production, the wire arrangement plate 31 needs to be selected according to the number of wire bundles and the required wire bundle spacing. Therefore, the wire arrangement plate 31 of this invention adopts an installation structure that facilitates disassembly and replacement. The wire arrangement frame 3 of this invention includes an H-shaped frame body 32 and two insert plate seats 33, which are symmetrically installed on the inner side of the H-shaped frame body 32. Figure 4 As shown, the insert plate holder 33 has a vertical groove 331 that runs vertically through it. One side of the vertical groove 331 is open. The width of the vertical groove 331 matches the thickness of the fiber-refining plate 31. The insert plate holder 33 is used to install the fiber-refining plate 31. The distance between two insert plate holders 33 corresponds to the width of the fiber-refining plate 31. The fiber-refining plate 31 can be inserted into two insert plate holders 33, such as... Figure 3 As shown, the left and right sides of the wire-arranging plate 31 are connected to the positioning stops 312. The two positioning stops 312 are symmetrically arranged. The positioning stops 312 can rest on the insert plate seat 33 so that the wire-arranging plate 31 cannot fall down and achieve positioning and fixation.

[0024] like Figure 1 As shown, to facilitate the movement of the filament bundle, this invention arranges the raw filament frame 1, the rate detection frame 4, and the filament sorting frame 3 in a straight line, as follows: Figure 2As shown, this utility model has an upper detection element (41) and a lower detection element (42) installed in the speed detection frame 4. The upper detection element 41 is located directly above the lower detection element 42, and a filament passage space is formed between the upper detection element 41 and the lower detection element 42. The normally moving filament passes through this space. In this utility model, the installation height of the filament output device 2 and the filament sorting plate 31 are both set to be higher than the upper detection element 41, and the filament is set to a naturally drooping state to pass through the space between the upper detection element 41 and the lower detection element 42. Therefore, the filament forms a V-shaped motion trajectory 5 between the upper detection element 41 and the lower detection element 42. The advantage of the filament naturally drooping in the speed detection frame 4 is that, firstly, when there is an error in the speed at both ends of the filament, the filament itself can have a tolerance space; secondly, the drooping state of the filament can be used to detect and judge the cumulative amount of speed deviation. The specific method is as follows: if If the filament output speed of the filament feeder 2 is consistently greater than the filament pulling rate, the filament will gradually droop until it contacts the lower detection element 42. The lower detection element 42 then sends a trigger signal to slow down the filament output speed of the filament feeder 2, making it less than the filament pulling rate. This gradually eliminates the drooping deviation. If the filament output speed of the filament feeder 2 is consistently less than the filament pulling rate, the filament will gradually rise. The risen filament will then contact the upper detection element 41, which then sends a trigger signal to increase the filament output speed of the filament feeder 2, making it greater than the filament pulling rate. This gradually eliminates the rising deviation. Due to the presence of the upper and lower detection elements 41, the degree of filament drooping is controlled within a reasonable range, and the production of fiberglass profiles is not affected.

[0025] The lower detection element 42 is mainly intended to contact the bottom of the drooping filament bundle, therefore, as Figure 2 As shown, the lower detection element 42 adopts a horizontally mounted sensing plate 421, and the plate-shaped sensing element is more suitable for the filament bundle to sink to the bottom for contact.

[0026] The upper detection element 41 mainly needs to contact the raised outer wall of the filament bundle, therefore, if Figure 2 As shown, the upper detection element 41 adopts a roller structure design. The upper detection element 41 includes two symmetrically installed triangular supports 411. Two sensing rollers 412 are installed between the two triangular supports 411. The two sensing rollers 412 are symmetrically arranged on both sides of the yarn feed direction (the direction of the yarn feed rate detection frame 4). The raised outer wall of the yarn feed will contact the sensing rollers 412 to form a sensing signal. The sensing rollers 412 have a circular cross section. When the yarn feed contacts, it will not cause damage to the yarn feed. The purpose of setting two symmetrical sensing rollers 412 is to detect deviations exceeding the standard in a timely manner. A sensing signal will be generated regardless of which one contacts.
