Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber stitched felt processing equipment, specifically a glass fiber stitched felt rough edge cutting device. Background Technology

[0002] Fiberglass stitch-bonded mat is a composite material made of fiberglass using a stitch-bonding technique rather than traditional weaving. It consists of multiple layers of fiberglass mesh or yarn arranged in a specific direction, then bound together using heat-resistant and high-strength stitching to form a monolithic structure.

[0003] The fiberglass stitched felt edge trimming device is a specialized piece of equipment designed to process the edges of fiberglass stitched felt, aiming to achieve efficient and precise edge removal, thereby improving material utilization and product quality. This device is typically equipped with high-precision cutting tools and a sensing system that automatically identifies the edges of the stitched felt and performs precise cutting according to preset parameters, avoiding errors and irregularities that may occur with manual operation.

[0004] Although existing burr shearing devices can efficiently and accurately remove burrs, they do not have the function of trimming burrs on the surface of fiber felt. This limitation may result in unwanted fiber protrusions remaining on the surface, affecting the overall quality and performance of the product. It may also pose health risks to operators and limit the applicability of the device in application scenarios with high requirements for surface smoothness. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass stitched felt burr trimming device to solve the problem mentioned in the background art of being unable to repair the burrs on the surface of fiberglass stitched felt, which affects the overall quality and performance of the product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glass fiber stitched felt burr shearing device, comprising a frame, a burr orientation mechanism fixedly installed on the top of the frame, a burr repair mechanism fixedly installed inside the burr orientation mechanism, a burr collection mechanism fixedly installed on one side of the burr orientation mechanism, an edge trimming device fixedly installed on the top of the frame, the burr orientation mechanism comprising a first mounting frame, an electrostatic activation module fixedly installed on the top of the first mounting frame, a first control module fixedly installed on one side of the electrostatic activation module, a positive electrode plate fixedly installed on one side of the first control module, a negative electrode plate fixedly installed on one side of the first control module, and the positive electrode plate being disposed on top of the negative electrode plate;

[0007] The burr repair mechanism includes a second mounting bracket, on the bottom of which an electrothermal cutting wire is fixedly mounted. The electrothermal cutting wire is disposed between the positive electrode plate and the negative electrode plate. On the top of the second mounting bracket, a second control module for controlling the operating status of the electrothermal cutting wire is fixedly mounted.

[0008] Preferably, the burr repair mechanism further includes a third mounting bracket, on the top of which a drive assembly is fixedly mounted. The telescopic shaft of the drive assembly is fixedly connected to the top of a second mounting bracket. An extension rod is fixedly mounted on one side of the second mounting bracket, and a distance sensor is fixedly mounted on one end of the extension rod.

[0009] Preferably, the electric field strength between the positive and negative electrode plates decreases along the direction of fiber felt movement.

[0010] Preferably, a drying module is provided on the side of the electrostatic activation module away from the first control module, and a humidity sensor is provided on the side of the drying module away from the electrostatic activation module.

[0011] Preferably, the burr collection mechanism includes a filter and a suction hood. The suction hood is disposed on top of the electrothermal cutting line. A fan is fixedly installed on one side of the filter. A material removal box is movably connected to the bottom of the filter. A connecting pipe is fixedly connected to the top of the filter. The filter is fixedly connected to one side of the suction hood through the connecting pipe.

[0012] Preferably, a plurality of brackets are fixedly installed on the top of the suction hood, and the connecting tube is disposed on the top of the brackets.

[0013] Preferably, the burr orientation mechanism further includes a surface potentiometer and a plurality of insulating pillars, wherein the plurality of insulating pillars are disposed between the positive electrode plate and the negative electrode plate, and the surface potentiometer is disposed between the first control module and the electrostatic activation module.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the fiberglass stitch-woven felt rough edge cutting device;

[0015] 1. The fiber felt is trimmed on both sides by the edge trimming device and the surface of the fiber felt is uniformly attached with negative charge by the electrostatic activation module. Then, the loose fibers are driven to stand upright by the electric field force between the positive and negative plates. Finally, the loose fibers are cut by the high-temperature electrothermal cutting line. It has the advantages of both processing rough edges and repairing surface burrs.

[0016] 2. By setting the electric field strength between the positive and negative plates to decrease along the direction of fiber felt movement to form a gradient field for traction and shaping, an asymmetric electrode structure is adopted. The electric field strength gradient changes along the conveying direction, realizing the two-step action of traction and shaping, improving the stability of upright fibers. The initial high electric field strength quickly overcomes the adhesion force between the fiber and the substrate, and the reduced electric field strength suppresses fiber rebound. Compared with the high electric field strength throughout the process, energy consumption is reduced.

[0017] 3. By using the fan and connecting pipes to create negative pressure inside the suction hood, the cut fibers are drawn into the filter and stored inside the material collection box. This process collects and treats the cut fibers, preventing them from scattering and protecting workers from harm, thus providing safer working conditions. Attached Figure Description

[0027] Please see Figure 1-3This utility model provides a technical solution: a fiberglass stitched felt edge trimming device, including a frame 1, a burr orientation mechanism 2 fixedly installed on the top of the frame 1, a burr repair mechanism 3 fixedly installed inside the burr orientation mechanism 2, a burr collecting mechanism 4 fixedly installed on one side of the burr orientation mechanism 2, and an edge trimming device 5 fixedly installed on the top of the frame 1. The edge trimming device 5 trims the edges of both sides of the fiber felt. The burr orientation mechanism 2 includes a first mounting frame 201, an electrostatic activation module 202 fixedly installed on the top of the first mounting frame 201, and a first control module 203 fixedly installed on one side of the electrostatic activation module 202. A positive electrode plate 204 is fixedly installed on one side of module 203, and a negative electrode plate 205 is fixedly installed on one side of the first control module 203. The positive electrode plate 204 is located on top of the negative electrode plate 205. A drying module 209 is located on the side of the electrostatic activation module 202 away from the first control module 203. A humidity sensor 208 is located on the side of the drying module 209 away from the electrostatic activation module 202. The humidity sensor 208 detects the surface humidity of the fiber felt, and the drying module 209 dries the surface of the fiber felt to prevent excessive surface humidity from causing rapid leakage of static charge. The burr orientation mechanism 2 also includes a surface potentiometer 207 and several insulating pillars 206. Several insulating pillars 206 are disposed between the positive electrode plate 204 and the negative electrode plate 205. A surface potentiometer 207 is disposed between the first control module 203 and the electrostatic activation module 202. The surface potentiometer 207 ensures that the positive electrode plate 204 and the negative electrode plate 205 are parallel to each other and monitors the charge density in real time. The burr repair mechanism 3 includes a second mounting bracket 301. An electrothermal cutting wire 303 is fixedly mounted at the bottom of the second mounting bracket 301 and is disposed between the positive electrode plate 204 and the negative electrode plate 205.

The burr repair mechanism 3 also includes a third mounting bracket 306. A drive assembly 307 is fixedly mounted on the top of the third mounting bracket 306. The telescopic shaft of the drive assembly 307 is fixedly connected to the top of the second mounting bracket 301. An extension rod 304 is fixedly mounted on one side of the second mounting bracket 301. A distance sensor 305 is fixedly mounted on one end of the extension rod 304. The distance between the electrothermal cutting wire 303 and the surface of the fiber felt is calculated by the distance sensor 305. Then, the distance between the electrothermal cutting wire 303 and the surface of the fiber felt is controlled by the drive assembly 307 controlling the up and down displacement of the second mounting bracket 301, thereby achieving the purpose of accurately controlling the trimming height.

[0028] This utility model's fiberglass stitched felt edge trimming device can trim unwanted fiber protrusions on both sides and the surface of the fiber felt. The edge trimming device 5 trims the edges of the fiber felt, and the electrostatic activation module 202 evenly attaches a negative charge to the surface of the fiber felt. Then, the electric field between the positive electrode plate 204 and the negative electrode plate 205 drives the loose fibers to stand upright. Finally, the high-temperature electrothermal cutting wire 303 cuts the loose fibers, providing the advantage of both trimming rough edges and surface burrs. Specifically: the edge trimming device 5 trims the edges of the fiber felt. When the fiber felt enters the electrostatic activation module 202, the DC high voltage ionization of the air generates a negative ion cloud. The negative ions attach to the fiber surface, forming a uniformly distributed electrostatic charge. Then, the positive electrode plate 204 attracts the negatively charged fibers upwards, while the lower negative electrode plate 205 repels them. The combined force makes the loose fibers stand upright, facilitating the cutting by the electrothermal cutting wire 303.

[0029] Example 2

[0030] See Figure 1-3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the electric field strength between the positive electrode plate 204 and the negative electrode plate 205 decreases along the direction of fiber felt movement. The gradient field formed by the above setting adopts an asymmetric electrode structure, and the electric field strength gradient changes along the conveying direction to realize the two-step action of traction and shaping, improve the stability of upright fibers, and the initial high electric field strength quickly overcomes the adhesion force between the fiber and the substrate. The reduced electric field strength suppresses fiber rebound. Compared with the high electric field strength throughout the process, the energy consumption is reduced.

[0031] Example 3

[0032] See Figure 1-4 In another preferred embodiment of this utility model, the difference from embodiment 1 is that the burr collection mechanism 4 includes a filter 401 and a suction hood 405.

A material removal box 403 is movably connected to the bottom of the filter 401. A connecting pipe 404 is fixedly connected to the top of the filter 401.

The connecting pipe 404 is set on the top of the brackets 406. The connecting pipe 404 is fixed by several brackets 406 to ensure the overall neatness and aesthetics of the equipment. The negative pressure generated inside the suction hood 405 by the cooperation between the fan 402 and the connecting pipe 404 draws the cut fibers into the filter 401 and stores them inside the material removal box 403. The cut fibers are collected and processed to prevent the fibers from flying around, thereby protecting the workers from harm and providing safer working conditions.
