Description

Technical Field

[0001] This utility model belongs to the field of static electricity elimination technology, and more specifically, it relates to an adjustable static electricity elimination device. Background Technology

[0002] In the production process of latex filaments, static electricity needs to be eliminated by using an ion fan. An ion fan is mostly composed of a fan, a high-voltage power generator, and a discharge electrode. The air is ionized into a large number of positive and negative ions by the discharge of the high-voltage power at the tip. Then, the fan blows the positive and negative ions onto the surface of the latex filaments to neutralize the static electricity.

[0003] For example, CN221688881U discloses an ion fan, including a front shell, a rear shell, and a discharge structure. The front shell and the rear shell are connected to form a mounting cavity. A front air window is detachably provided on the front side of the front shell, and a rear air window is fixedly provided on the rear side of the rear shell. The discharge structure includes a fan box, a fan, a mounting plate, and a discharge needle assembly disposed in the mounting cavity. The fan box has an inner cavity that runs through its front and rear sides. The fan is disposed in the inner cavity. The mounting plate is located in front of the inner cavity. Multiple connectors are spaced apart on the outer circumferential surface of the mounting plate. The end of the connector away from the mounting plate is disposed on the front side of the fan box. An air duct communicating with the inner cavity is formed between two adjacent connectors. The discharge needle assembly includes a placement plate, a clamping sheet metal part, multiple discharge needles, and a cover. An annular boss is formed on the front side of the mounting plate, and the placement plate is placed inside the boss. This utility model facilitates the cleaning, maintenance, and replacement of the discharge needles, greatly satisfying the usage requirements.

[0004] Based on the above, most ion blowers are fixed to the frame of the production equipment with bolts. When the bolts become loose, it will cause the ion blower to vibrate violently during operation. The bolts need to be tightened in time. Otherwise, the bolts are prone to falling off when exposed to vibration for a long time. Therefore, it is necessary to check the looseness of the bolts regularly. However, frequent bolt checks will result in a heavy workload for the staff and will take a long time, affecting the efficiency of the inspection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable electrostatic eliminator. This addresses the issue that ion blowers are mostly fixed to the frame of production equipment with bolts. When these bolts loosen, the ion blower will vibrate violently during operation, requiring timely tightening. Otherwise, the bolts may fall off due to prolonged exposure to vibration. Therefore, regular inspections of bolt looseness are necessary. However, frequent bolt inspections place a heavy workload on workers and are time-consuming, impacting inspection efficiency.

[0006] The purpose and effect of this adjustable static electricity elimination device are achieved by the following specific technical means: An adjustable electrostatic eliminator includes an ion fan body, a positioning mounting frame, buffer rubber pads, a filter structure, a detection structure, damping elastic elements, metal contact rings, and positioning mounting seats. The positioning mounting frame is rotatably connected to the outside of the ion fan body. Multiple buffer rubber pads are evenly distributed and fixedly connected to the lower end face of the positioning mounting frame. The filter structure is located on the front side of the ion fan body. Multiple damping elastic elements are evenly distributed and located on the inner sides of the buffer rubber pads. Multiple metal contact rings are evenly distributed and adhered to the inner sides of the buffer rubber pads. Multiple positioning mounting seats are fixedly connected to the lower parts of the damping elastic elements. The detection structure is located on the outside of the positioning mounting frame.

[0007] Furthermore, the filter structure includes a limiting mounting box and a second winding shaft; two limiting mounting boxes are provided, and the two limiting mounting boxes are respectively bolted to the upper and lower sides of the ion fan body; the second winding shaft is rotatably connected to the middle of the lower limiting mounting box.

[0008] Furthermore, the filter structure also includes a first winding shaft and a tension spiral spring; the first winding shaft is rotatably connected to the middle of the upper limiting mounting box; two tension spiral springs are provided, and the first winding shaft is elastically connected to the upper limiting mounting box through the two tension spiral springs.

[0009] Furthermore, the filter structure also includes a direction-limiting ratchet and a direction-limiting pawl; the direction-limiting ratchet is fixedly connected to the outside of the second take-up shaft; the direction-limiting pawl is hinged to the inside of the lower limiting mounting box by a torsion spring, and the direction-limiting ratchet and the direction-limiting pawl together constitute a ratchet transmission mechanism.

[0010] Furthermore, the filter structure also includes antistatic nonwoven fabric and limiting fastening bolts; the two ends of the antistatic nonwoven fabric are respectively fixedly connected to the outside of the first winding shaft and the outside of the second winding shaft; two limiting fastening bolts are provided, and the two limiting fastening bolts are respectively threaded to the left and right sides of the ion fan body.

[0011] Furthermore, the detection structure includes an audible and visual alarm and metal contact pins; the audible and visual alarm is bolted to the upper part of the ion fan body; multiple metal contact pins are provided, and the multiple metal contact pins are evenly distributed and fixedly connected to the outside of multiple positioning mounting seats; the multiple positioning mounting seats are connected in series with the control circuit of the audible and visual alarm through wires; and the multiple metal contact rings are connected in series with the control circuit of the audible and visual alarm through wires.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention allows for flexible angle adjustment to adapt to the positional requirements of latex threads in different production scenarios, enhancing the equipment's adaptability to diverse production environments and shortening downtime during angle adjustments. The combination of buffer rubber pads and damping elastic components significantly reduces the possibility of bolt loosening, minimizing equipment vibration caused by loose bolts. This reduces the workload of frequent bolt checks by staff and avoids long-term vibration-induced wear on equipment components, ensuring stable equipment operation. Furthermore, the antistatic non-woven fabric intercepts large dust particles in the ion airflow, preventing dust from adhering to the latex thread surface and causing contamination, thus improving product cleanliness and quality. The first and second take-up shafts enable convenient replacement of the antistatic nonwoven fabric. The tensioning spiral spring keeps the nonwoven fabric taut, ensuring filtration efficiency. Directional limiting ratchet and pawl prevent contaminated antistatic nonwoven fabric from shifting back, avoiding secondary contamination. Operation is simple and efficient, reducing the time spent replacing antistatic nonwoven fabric. An audible and visual alarm automatically activates when bolts become loose, promptly reminding staff to tighten them. This prevents increased equipment vibration, reduced static elimination efficiency, or component damage caused by loose bolts, reducing staff workload, saving significant time, improving inspection efficiency, and extending equipment lifespan.

[0023] The filter structure also includes a directional limiting ratchet 105 and a directional limiting pawl 106. The directional limiting ratchet 105 is fixedly connected to the outside of the second take-up shaft 104. The directional limiting pawl 106 is hinged to the inside of the lower limiting mounting box 101 by a torsion spring. The directional limiting ratchet 105 and the directional limiting pawl 106 together constitute a ratchet transmission mechanism.

[0024] The filter structure also includes antistatic nonwoven fabric 107 and limiting fastening bolts 108; the two ends of the antistatic nonwoven fabric 107 are respectively fixedly connected to the outside of the first winding shaft 102 and the outside of the second winding shaft 104; there are two limiting fastening bolts 108, and the two limiting fastening bolts 108 are respectively threaded to the left and right sides of the ion fan body 1.

[0025] The specific usage and function of this embodiment are as follows: When installing the ion fan, first attach the positioning mounting bracket 2 to the appropriate position of the equipment frame, and then screw the bolts into the mounting holes to press the positioning mounting bracket 2. At this time, the buffer rubber pad 3 and the damping elastic element 4 are compressed, and the restoring force of the buffer rubber pad 3 and the damping elastic element 4 can apply a reverse thrust to the positioning mounting bracket 2, reducing the possibility of bolt loosening. When it is necessary to adjust the angle of the ion fan, loosen the limiting fastening bolt 108 to directly rotate the ion fan body 1. After adjustment, tighten the limiting fastening bolt 108 to fix the angle of the ion fan body 1. At this time, the ion fan will blow the ion airflow towards the latex filaments to neutralize the static electricity on the surface of the latex filaments.

[0028] The specific usage and function of this embodiment are as follows: When the bolts become loose, the pressure on the buffer rubber pad 3 and the damping elastic element 4 will decrease. At this time, the restoring force of the damping elastic element 4 will push the positioning mounting seat 6 to move. At the same time, the part of the buffer rubber pad 3 subjected to the pressure of the positioning mounting seat 6 will deform accordingly. At this time, the metal contact pin 601 will contact the metal contact ring 5, so that the control circuit of the metal contact pin 601, the metal contact ring 5 and the audible and visual alarm 109 forms a circuit, so that the audible and visual alarm 109 is activated and sounds an alarm, reminding the staff to tighten the bolts in time.
