Description

Technical Field

[0001] This utility model relates to an antistatic spraying device, and more particularly to an automatic antistatic spraying device for unwinding fiberglass yarn. Background Technology

[0002] Unwinding of fiberglass yarn is a core step in fiberglass processing, directly determining the stability of subsequent processes and the quality of the finished product. The core function of unwinding is to orderly unfold the yarn from the bobbin and adjust it into a shape suitable for pultrusion, weaving, or composite material production. Due to the smooth surface and high brittleness of fiberglass, in addition to avoiding increased yarn hairiness and breakage rates through tension control and yarn guide path optimization, the unwinding process also requires addressing the entanglement problem caused by static electricity accumulation.

[0003] Currently, most mainstream antistatic devices use fixed antistatic bars or ion fans, relying on the principle of passive charge neutralization. This has the following shortcomings: First, the equipment layout is simple and cannot dynamically compensate for static distribution along the unwinding path, resulting in static residue in some areas of the yarn. Second, there is a lack of an active control mechanism linked to the unwinding action, which cannot adjust the antistatic intensity in real time according to changes in yarn speed and tension, resulting in energy waste or incomplete antistatic elimination. Third, existing devices are mostly independent additional structures, not integrated with the unwinding equipment, occupying space and easily interfering with the yarn guiding path, causing yarn misalignment or friction damage. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the objective is to provide an automatic anti-static spraying device for unwinding glass fiber yarn.

[0005] The technical solution is: an automatic anti-static spraying device for unwinding fiberglass yarn, comprising a housing, a quick-release cover, a mounting frame, a fixing plate, wire blocks, a mounting plate, a fixing seat, a lead wheel, a fan, a blower, a nozzle, a spray head, a spray nozzle, a liquid container, and a pump. A lead-wire window is opened on the front side of the housing, and a quick-release cover is installed at the lead-wire window. A mounting frame is installed at the rear of the housing. Fixing plates are fixed to the top of the housing and the lower front side of the housing. Multiple wire blocks are arranged horizontally on each fixing plate. Lead-wire notches are opened on the top of the housing and the lower part of the quick-release cover. The housing contains... The upper part is equipped with a mounting plate, and the lower part of the mounting plate is equipped with multiple fixing seats at horizontal intervals. The number of fixing seats is the same as the number of wire blocks on a single fixing plate. Each fixing seat is equipped with a lead wheel. A fan is installed at the upper rear of the box, and an air box is installed at the air outlet of the fan. The front of the air box extends into the upper part of the box. A nozzle is installed at the front of the air box, and several nozzles are evenly spaced on the nozzle. A liquid container is installed at the upper left of the box. A liquid pump is installed on the left side of the box near the liquid container. The input end of the liquid pump extends into the lower part of the liquid container, and its output end is connected to the internal space of the air box.

[0006] Furthermore, it also includes a wire frame and a winding sleeve. Multiple wire frames are arranged horizontally on the mounting plate, and the number of wire frames is the same as the number of lead wheels. Wire holes are opened at the top and bottom of the wire frames, and winding sleeves are vertically installed inside each wire frame.

[0007] Furthermore, it also includes conductive bolts and conductive modules. The winding sleeves are made of conductive material, and each conductor frame is equipped with conductive bolts. The conductive bolts are all connected to the winding sleeves on the same conductor frame. The rear of the mounting plate is equipped with conductive modules, and the conductive bolts are all connected to the conductive modules through conductors.

[0008] Furthermore, it also includes a collection box, which is located in the lower part of the box.

[0009] Furthermore, it also includes a filter element, a reflux pump, and a reflux pipe. The filter element is installed on the lower left side of the housing, and the reflux pump is installed on the left side of the housing near the filter element. The output end of the reflux pump is connected to and communicates with the filter element, and the input end of the reflux pump extends into the lower part of the collection frame. The reflux pipe is installed on the upper part of the filter element, and the other end of the reflux pipe is connected to and communicates with the liquid container.

[0010] Furthermore, the quick-release cover is equipped with a transparent protective plate.

[0011] The beneficial effects are as follows: 1. This utility model sets up a closed spray-type antistatic device on the transmission path of the yarn unwinding process. During the yarn unwinding process, an antistatic liquid atomization layer is evenly sprayed into the closed space of the device, which directly wraps the yarn surface, quickly neutralizes the static charge, and avoids the fibers from tangling, breaking, or dust adhesion caused by static adsorption. At the same time, the closed design blocks external airflow interference, ensuring that the yarn is stably transmitted along the guide path, making the unwinding process continuous and smooth, and improving the quality and efficiency of subsequent processing.

[0012] 2. This utility model incorporates a winding sleeve within the housing. During yarn routing, the yarn naturally winds along its outer surface to form an arc-shaped guide path. Utilizing the inherent geometric characteristics of the sleeve, it evenly releases the internal tension of the yarn, eliminating localized twisting or shrinkage caused by stress concentration. Simultaneously, the smooth and gentle contact surface of the winding sleeve guides the yarn to extend smoothly, reducing fiber damage caused by friction and vibration. This ensures that the yarn maintains stable shape and balanced tension during subsequent processing, fundamentally preventing problems such as yarn breakage and loosening.

[0013] 3. This utility model collects sprayed droplets in a collection frame, removes impurities with a filter component, and then returns the liquid to the liquid container via a reflux mechanism, thus realizing the recycling and reuse of antistatic liquid. This avoids liquid residue from contaminating equipment or the environment, maintains the cleanliness of the working area, reduces the frequency of manual cleaning, and ensures the stable purity of the recycled liquid to avoid secondary pollution. This reduces resource consumption and improves the sustainability of system operation. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] An automatic anti-static spraying device for unwinding fiberglass yarn, such as Figure 1-6 As shown, the device includes a housing 1, a quick-release cover 2, a mounting bracket 21, a fixing plate 3, a wire block 4, a mounting plate 41, a fixing base 42, a lead wire wheel 43, a fan 5, a blower box 51, a nozzle 52, a spray nozzle 53, a liquid container 6, and a liquid pump 61. The housing 1 has a lead wire window on the front side, and a quick-release cover 2 is provided at the lead wire window of the housing 1. The quick-release cover 2 is detachably connected to the housing 1 by a hinge or snap-fit ​​structure, which facilitates quick opening and closing during wiring and improves operating efficiency. The rear of the housing 1 is equipped with a mounting bracket 21, which is fixedly connected to the housing 1 by bolts or welding, providing a stable mounting base for other components.

[0024] A fixing plate 3 is fixedly installed on the top of the housing 1 and the lower front side of the housing 1. The fixing plate 3 is firmly connected to the housing 1 by welding or screws. Multiple wire guide blocks 4 are arranged horizontally on the fixing plate 3. The wire guide blocks 4 are evenly distributed on the fixing plate 3 to guide the direction of the yarn, ensuring that the yarn remains orderly during transmission and avoiding tangling. There are wire guide notches on the top of the housing 1 and the lower part of the quick-release cover 2. These two wire guide notches correspond to each other and provide a channel for the yarn to enter the housing from the outside, ensuring that the yarn can pass smoothly through the housing for subsequent processing. The upper part of the housing 1 is provided with a mounting plate 41, which is connected to the inner wall of the housing 1 by screws or welding. Multiple fixing seats 42 are provided at horizontal intervals at the lower part of the mounting plate 3. The number of fixing seats 42 is the same as the number of wire blocks 4 on a single fixing plate 3. Each fixing seat 42 is equipped with a guide wheel 43. The guide wheel 43 can rotate freely. When the yarn passes around the lower part of the guide wheel 43, the friction between the yarn and the fixing parts can be reduced, the yarn wear can be reduced, and the yarn can maintain a certain tension during transmission to ensure the transmission stability of the yarn.

[0025] A fan 5 is provided at the upper rear of the housing 1. The fan 5 is fixedly connected to the housing 1 by bolts or brackets. An air box 51 is provided on the air outlet of the fan 5. The air box 51 is tightly connected to the air outlet of the fan 5. The front part of the air box 51 extends into the upper part of the housing 1, which can guide the airflow generated by the fan 5 into the interior of the housing 1. A nozzle 52 is installed at the front of the air box 51. The nozzle 52 is connected to the air box 51 by threads or snaps. Several nozzles 53 are evenly spaced on the nozzle 52. When the fan 5 is working, the airflow enters the nozzle 52 through the air box 51 and then sprays out from the nozzle 53, forming a uniform airflow distribution, which helps to evenly atomize and disperse the liquid agent in the housing 1. A liquid container 6 is installed on the upper left side of the housing 1. The liquid container 6 is fixedly connected to the housing 1 by a bracket or bolts and is used to store antistatic liquid. A liquid pump 61 is provided on the left side of the housing 1 near the liquid container 6. The liquid pump 61 is fixedly connected to the housing 1 by bolts or clips. The input end of the liquid pump 61 extends into the lower part of the liquid container 6 and can fully extract the liquid in the liquid container 6. Its output end is connected to the internal space of the air box 51. When the liquid pump 61 is working, it can extract the liquid from the liquid container 6 and transport it into the air box 51.

[0026] During wiring, the quick-release cover 2 is removed from the housing 1, fully opening the lead-in window and providing ample space for wiring operations. A single yarn is passed through a guide block 4 at the top. The smooth inner wall of the guide block 4 reduces friction between the yarn and the block, protecting the yarn fibers from damage. The yarn enters the housing 1 through the lead-in notch, then passes under a lead-in reel 43 inside the housing 1. The free rotation of the lead-in reel 43 allows the yarn to smoothly change direction, preventing breakage due to excessive bending. The yarn is then passed forward through a guide block 4 at the front of the housing 1, and the above operation is repeated to lay multiple yarns sequentially, completing the wiring on the device. This wiring method ensures that multiple yarns are arranged orderly within the device without interference, guaranteeing the smooth progress of the subsequent unwinding and static elimination process.

[0027] During the dewinding and static elimination stage, liquid agent is intermittently drawn into the air box 51 by the liquid pump 61. The intermittent operation of the liquid pump 61 can be adjusted according to actual production needs to avoid waste. The blower 5 operates, generating a strong airflow that sprays the liquid agent in droplet form from the nozzle 53 of the nozzle 52, dispersing it within the box 1. The airflow generated by the blower 5 enables more uniform atomization of the liquid agent, allowing the droplets to more comprehensively cover the yarn surface. The droplets dispersed within the box 1 fully contact the yarn, quickly neutralizing the static charge on the yarn surface and preventing fibers from tangling, breaking, or adhering to dust due to electrostatic adsorption, thus ensuring yarn quality and smooth subsequent processing. At the same time, the uniform airflow and droplet distribution also help to evenly adhere the liquid agent to the yarn, improving the static elimination effect.

[0028] Example 2

[0029] Based on Example 1, such as Figure 2 and Figure 5As shown, it also includes a conductor frame 8 and a winding sleeve 81. Multiple conductor frames 8 are arranged horizontally on the mounting plate 41. The number of conductor frames 8 is the same as the number of lead wheels 43, ensuring that each yarn has a corresponding guiding structure. The conductor frames 8 have conductor holes at the top and bottom to provide channels for the yarn to enter and exit. Each conductor frame 8 is vertically equipped with a winding sleeve 81. When the yarn enters through the lead wire notch in the housing 1, the yarn end is threaded through the upper part of the conductor frame 8 and then wound around the winding sleeve 81 once. The outer surface of the winding sleeve 81 is smooth, which can reduce the friction between the yarn and the winding sleeve 81 and prevent the yarn from being damaged during the winding process. By allowing the yarn to naturally wind around the outer surface of the winding sleeve to form an arc-shaped guide path during transmission, the internal tension of the yarn is evenly released using its own geometric characteristics, eliminating local twisting or shrinkage caused by stress concentration. At the same time, the smooth and soft contact surface of the winding sleeve can guide the yarn to stretch gently, reduce fiber damage caused by friction and vibration, and ensure that the yarn maintains shape stability and tension balance in subsequent processing. The yarn end is then threaded out from the conductor hole at the bottom of this conductor frame 8 and then wound onto a lead wire wheel 43 at the corresponding position.

[0030] like Figure 2 and Figure 5 As shown, it also includes conductive bolts 82 and conductive modules 83. The winding sleeve 81 is made of conductive material, and each wire frame 8 is equipped with conductive bolts 82. The conductive bolts 82 are threadedly connected to the wire frame 8 to ensure a firm connection. The conductive bolts 82 are all connected to the winding sleeves 81 on the same wire frame 8, forming a good conductive path. The rear of the mounting plate 41 is equipped with a conductive module 83. The conductive bolts 82 are all connected to the conductive module 83 through conductors. When the yarn is wound on the winding sleeve 81, the yarn comes into contact with the winding sleeve 81. If the yarn carries static electricity, the static electricity can be conducted through the winding sleeve 81 and the conductive bolts 82 to the conductive module 83, and finally conducted to the ground, thereby cooperating with the spray component to further eliminate static electricity on the yarn.

[0031] like Figure 3 and Figure 4 As shown, it also includes a collection frame 71. The collection frame 71 is provided in the lower part of the box body 1. The collection frame 71 is used to collect droplets in the box body 1. The internal space of the collection frame 71 is gradually transitioned from large at the top to small at the bottom, which allows the droplets to naturally converge to the bottom of the collection frame 71 under the action of gravity, which is convenient for subsequent recycling and processing, avoids droplets remaining in the collection frame 71, and improves the droplet collection efficiency.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a filter element 7, a reflux pump 72, and a reflux pipe 73. The filter element 7 is installed on the lower left side of the housing 1. The filter element 7 has a multi-layer filtration structure inside, which can effectively filter impurities in the droplets. The reflux pump 72 is installed on the left side of the housing 1 near the filter element 7. The reflux pump 72 is fixedly connected to the housing 1 by bolts or brackets. The output end of the reflux pump 72 is connected to and communicates with the filter element 7. The input end of the reflux pump 72 extends into the lower part of the collection frame 71, which can extract the droplets in the collection frame 71. The reflux pipe 73 is installed on the upper part of the filter element 7. The other end of the reflux pipe 73 is connected to and communicates with the liquid container 6. The liquid extracted by the reflux pump 72 is filtered by the filter element 7 and then flows back to the liquid container 6 through the reflux pipe 73, realizing the recycling of the liquid and reducing production costs.

[0033] In a preferred embodiment: such as Figure 1 As shown, the quick-release cover 2 is equipped with a transparent protective plate, which is connected to the quick-release cover 2 by a snap or adhesive. The transparent protective plate allows the operator to observe the wiring and spraying status of the yarn inside the box 1 without opening the quick-release cover 2, so as to discover and solve problems in time and improve the convenience and safety of operation.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
