Description

Technical Field

[0001] This invention belongs to the field of safety protection for glass fiber production equipment, specifically relating to an emergency stop device for a glass fiber primary twisting machine and its installation method. Background Technology

[0002] The glass fiber primary twisting machine is a long, multi-spindle structure with a large overall length and numerous twisting spindle positions, making it the core equipment in glass fiber twisting production. Currently, most glass fiber primary twisting machines on the market use a single-point fixed emergency stop button, which is only installed at the end of the machine.

[0003] In actual production, there are many defects: First, the machine body is long, and when operators encounter sudden failures such as yarn breakage, roller entanglement, or equipment jamming in the middle or far end of the machine body, they cannot quickly touch the emergency stop button, resulting in delayed emergency shutdown and easily causing equipment damage and personnel safety accidents; Second, the glass fiber production workshop has a large amount of dust and a complex environment, and the traditional button-type emergency stop structure is prone to dust accumulation, resulting in problems such as poor contact and malfunction; Third, some simple pull-rope emergency stop structures do not have protective designs, and are prone to entanglement with yarn and yarn breakage detection components, or false triggering, affecting normal production.

[0004] Therefore, considering the structural characteristics and production conditions of glass fiber initial twisting machines, designing an emergency stop device that is triggerable across the entire range, dustproof, interference-proof, and reliable in use has become a practical need in this field. Summary of the Invention

[0005] The purpose of this invention is to provide an emergency stop device for a glass fiber initial twisting machine and its installation method, so as to solve the problems of existing initial twisting machines having a single emergency stop point, slow emergency response, easy dust accumulation and failure, and easy to be accidentally triggered by yarn interference.

[0006] According to one objective of the present invention, an emergency stop device for a glass fiber primary twisting machine is provided, comprising two sets of emergency stop switches, a pull rope body, and multiple fixed supports; the two sets of emergency stop switches are respectively fixedly disposed at the left and right ends of the glass fiber primary twisting machine; the pull rope body is arranged horizontally along the length of the primary twisting machine, and both ends of the pull rope body are respectively connected to the two sets of emergency stop switches, and pulling the pull rope body can trigger the emergency stop switches to operate; the multiple fixed supports are distributed at intervals along the length of the primary twisting machine on the side wall of the machine, for supporting and limiting the pull rope body.

[0007] Furthermore, the emergency stop switch is externally covered with a dustproof cover, which is used to prevent fiberglass dust from entering the interior of the emergency stop switch.

[0008] Furthermore, a tension adjustment component is provided at the connection position between the pull rope body and the emergency stop switch, and the tension adjustment component is used to adjust the tension of the pull rope body.

[0009] Furthermore, the fixed bracket separates the pull rope body from the spindle position, yarn guiding component, and yarn breakage detection component of the initial twisting machine to prevent the yarn from tangling around the pull rope body.

[0010] Furthermore, the two sets of emergency stop switches are connected in series to the main control emergency stop circuit of the primary twisting machine. When any set of emergency stop switches is triggered, the power to the entire primary twisting machine is cut off, and all spindles stop operating synchronously.

[0011] Furthermore, the main body of the pull rope is a wear-resistant flexible pull rope, and a red safety rope is used.

[0012] Furthermore, the main body of the pull rope is arranged on the operating side of the primary twisting machine, and runs through the entire spindle area of ​​the primary twisting machine.

[0013] Furthermore, the tension adjustment assembly includes an adjustment bolt and a locking nut. The tension of the rope body is adjusted by turning the adjustment bolt and then fixed by the locking nut.

[0014] The present invention also provides a method for installing an emergency stop device for a glass fiber initial twisting machine, comprising the following steps: S1. Fix the left emergency stop switch and the right emergency stop switch on the frame at both ends of the glass fiber primary twisting machine body respectively, and install dustproof covers on the outside of the two emergency stop switches. S2. Multiple sets of fixed brackets are horizontally installed along the operating side of the primary twisting machine, and the multiple sets of fixed brackets are evenly distributed at intervals along the length direction of the primary twisting machine. S3. Pass the pull rope body through all the fixed brackets in sequence. The two ends of the pull rope body are connected to the left emergency stop switch and the right emergency stop switch respectively through the tension adjustment component. S4. Connect the left-end emergency stop switch and the right-end emergency stop switch in series to the original emergency stop control circuit of the initial twisting machine to complete the circuit wiring.

[0015] Furthermore, after step S4, a debugging step is also included: adjusting the tension of the pull rope body through the tension adjustment component to ensure that the pull rope body is horizontal without sagging or tightness; manually pulling the pull rope body to test that both the left-end emergency stop switch and the right-end emergency stop switch can be triggered normally and the entire initial twisting machine stops synchronously; checking the distance between the pull rope body and the spindle, yarn guide, and yarn breakage detection component to ensure no contact or interference.

[0016] The technical solution of this invention involves setting up an emergency stop switch at each of the left and right ends of the initial twisting machine, and connecting the two sets of switches in series with a pull rope arranged horizontally along the length of the machine. This allows the emergency stop to be triggered by pulling the pull rope from any position on the machine, completely eliminating the blind spots in operation of traditional single-point button-type emergency stops on long machine bodies. This significantly shortens the emergency stop response time in the event of sudden failures such as yarn breakage, roller entanglement, and jamming, effectively reducing the risk of equipment damage and personal injury. Simultaneously, fixed supports spaced along the length support and limit the pull rope, ensuring that the pull rope runs horizontally throughout its length, without sagging or deviating. This ensures that the triggering force of the pull rope is uniform and consistent throughout its length, guaranteeing that pulling at any point reliably triggers the switches at both ends, thus improving the reliability and consistency of the emergency stop device.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1 like Figures 1-3 As shown, this embodiment provides an emergency stop device for a glass fiber initial twisting machine, mainly composed of a pull rope body 1, an emergency stop switch 2, a fixed bracket 3, a tension adjustment component 4, a dustproof cover 5, and an equipment control circuit. The entire structure is installed on the existing initial twisting machine frame 6 without altering the main structure of the equipment, and does not affect normal routine operations such as yarn threading, splicing, and equipment maintenance.

[0024] There are two sets of emergency stop switches 2, including a left emergency stop switch 21 and a right emergency stop switch 22, which are fixed on the primary twisting machine frame 6 at the left and right ends of the primary twisting machine, respectively. The emergency stop switch 2 has a built-in mechanical triggering structure, and pulling the pull rope will trigger the switch to operate. The emergency stop switch 2 is externally covered with a dustproof cover 5, which prevents fiberglass dust from entering the switch and ensures good contact of the circuit contacts, making it suitable for the high-dust working environment of the fiberglass workshop.

[0025] The pull rope body 1 is made of wear-resistant flexible pull rope, specifically a red safety rope, which is arranged horizontally along the length of the glass fiber primary twisting machine and on the operating side, running through all spindle positions of the equipment, serving as a triggering component for the entire area. When the operator encounters sudden malfunctions such as yarn breakage, roller entanglement, or equipment jamming at any position on the machine, they can directly pull the nearest pull rope body 1 to trigger an emergency stop.

[0026] Fixed supports 3 are evenly distributed on the side wall of the machine to support and limit the pull rope body 1, ensuring that the pull rope runs horizontally. At the same time, fixed supports 3 separate the pull rope body 1 from the spindle, yarn guide component, and yarn breakage detection component to prevent yarn from getting tangled in the pull rope and avoid accidental triggering.

[0027] The tension adjustment component 4 is assembled at the connection point between the pull rope body 1 and the emergency stop switch 2, and is used to adjust the tension of the pull rope. Figure 3 As shown, the tension adjustment component 4 includes an adjustment bolt 41 and a locking nut 42. After adjusting the tension of the pull rope body 1 by turning the adjustment bolt 41, it is fixed by the locking nut 42 to prevent the pull rope from drooping due to being too loose or getting stuck due to being too tight, and to prevent accidental triggering caused by non-human touch.

[0028] In the equipment control circuit, two sets of emergency stop switches 2 are connected in series to the main control emergency stop circuit of the primary twisting machine. When either switch is triggered, the entire machine immediately cuts off the power, and all spindles stop operating synchronously.

[0029] The installation and debugging process of this invention is as follows: Installation steps: First, fix the left emergency stop switch 21 and the right emergency stop switch 22 to the frame 6 at both ends of the glass fiber primary twisting machine body, and install dustproof covers 5 on the outside of the two switches. Second, install multiple sets of fixed brackets 3 horizontally along the operating side of the equipment, with the brackets evenly spaced to ensure stable support. Then, pass the red pull rope body 1 through all the fixed brackets 3 in sequence, and connect the two ends of the pull rope to the emergency stop switches 2 at both ends through the tension adjustment components 4. Finally, connect the two emergency stop switches 2 in series to the original emergency stop control circuit of the primary twisting machine to complete the circuit wiring.

[0030] Debugging steps: Adjust the tension of the pull rope using the tension adjustment component 4 to ensure that the pull rope is horizontal without sagging or tightness; manually pull the pull rope to test that the emergency stop switches 2 at both ends can be triggered normally and the entire machine stops synchronously; check the distance between the pull rope and the spindle, yarn guide, and yarn breakage detection components to ensure that there is no contact or interference.

[0031] Use and Maintenance: During normal production, the pull rope is in a static tensioned state and does not affect the normal operation of the equipment. When a malfunction or safety hazard occurs at any position, the operator can directly pull the nearest pull rope to trigger an emergency stop, and the entire machine will immediately stop running. During routine maintenance, regularly clean the fiberglass dust from the dust cover and switch surface, and regularly check the wear and tension of the pull rope. Replace the pull rope in time if it is severely worn.

[0032] This invention features an emergency stop device for a glass fiber initial twisting machine with a pull rope structure along the entire length of the equipment. The emergency stop can be quickly triggered from any position on the machine, eliminating blind spots and ensuring rapid emergency shutdown. The emergency stop switch is covered with a dustproof cover, suitable for glass fiber dusty working environments. The switch operates stably, with good contact and is not prone to failure. The fixed bracket supports the limiting pull rope to ensure horizontal yarn routing and separates the pull rope from the spindle, yarn guide components, and yarn breakage detection components, preventing yarn tangling and accidental triggering. The tension adjustment component of this invention can adjust the tension of the pull rope, preventing excessive looseness and sagging or excessive tightness and jamming, eliminating accidental triggering due to non-human contact. The entire structure of this invention is installed on the existing machine frame without altering the main body of the equipment, making installation and maintenance convenient and reducing operating costs.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
