Description

Technical Field

[0001] This utility model relates to the field of needle-punched felt processing technology, specifically to a fiber-laminated needle-punched felt processing device. Background Technology

[0002] Fiber needle-punched felt is a type of fiber felt mat material used for filtration, heat insulation, insulation, and fireproofing. It is widely used in various industrial and environmental protection fields. Fiber needle-punched felt is suitable for different application scenarios, such as high-efficiency filters, ordinary filters, and dust filters. Fiber needle-punched felt is a high-efficiency, durable, and easy-to-use filter material. It has the characteristics of good air permeability, moisture resistance, corrosion resistance, high filtration efficiency, and long service life. It is widely used in air filtration, chemical, pharmaceutical, food, and defense industries. Proper use and maintenance of fiber needle-punched felt can ensure its long-term stable operation and achieve the expected filtration effect.

[0003] In the processing of fiber needle-punched felt, poor multi-layer rolling results can lead to many drawbacks and disadvantages. Multi-layer rolling is a common method to improve the quality and performance of needle-punched felt. If the rolling effect is poor, production efficiency will be affected, leading to production delays. Due to the poor rolling effect, more materials and time will be needed to achieve the expected results, which will increase production costs. Moreover, uneven rolling or misalignment will result in inconsistent dimensions and performance of the needle-punched felt, affecting the overall quality and consistency of the product. It will be unable to achieve better waterproof, anti-slip, and filtration functions, which will directly affect the performance of the needle-punched felt in practical applications, such as poor filtration effect and easy slippage, resulting in a decline in user experience. In some high-requirement scenarios (such as waterproof filtration), it will be unable to meet safety requirements.

[0004] In summary, to address the multi-layer rolling problem in the fiber needle-punched felt processing, we propose a fiber-laminated needle-punched felt processing device to improve the rolling process and enhance product quality and performance. Utility Model Content

[0005] The purpose of this invention is to provide a fiber-laminated needle-punched felt processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber-laminated needle-punched felt processing device, comprising two support plates arranged vertically symmetrically. Hydraulic cylinders are symmetrically fixedly connected between the inner sidewalls of the two support plates. A frame is fixedly connected at the center of the inner sidewall of each support plate. A servo motor is fixedly connected to the outer sidewall of the frame, and the output end of the servo motor penetrates through the sidewall of the frame. A grooved roller is fixedly connected to the output end of the servo motor. The other end of the grooved roller is rotatably connected to the inner wall of the frame. A pressure plate is attached to the sidewall of the grooved roller, and the inner sidewalls of the two pressure plates are in contact with each other.

[0007] Preferably, a concave frame is fixedly connected to the side wall of the bottom support plate, a bracket is fixedly connected to the center of the upper surface of the concave frame, and a small round roller is rotatably connected between the inner side walls of the bracket, with the upper surface of the small round roller in contact with the lower surface of the bottom pressure plate.

[0008] Preferably, the sidewall of the pressure plate is symmetrically provided with protrusions, and the outer ring wall of the grooved roller is symmetrically provided with grooves, and the protrusions of the pressure plate are in contact with the grooves on the sidewall of the grooved roller.

[0009] Preferably, the number of hydraulic cylinders is four, and they are arranged symmetrically.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When processing fiber-laminated needle-punched felt, the circular roller is modified to have symmetrical annular grooves, and pressure plates are clamped on both sides of the needle-punched felt layer. The pressure plates can engage with the grooves of the circular roller, maintaining the stability of the upper and lower pressure plates and preventing displacement during rolling. Simultaneously, a hydraulic cylinder is used to adjust the roller spacing. By using the circular roller with symmetrical annular grooves and corresponding pressure plates, the needle-punched felt can be better fixed, preventing displacement and loosening during rolling, thus improving processing stability and precision. The hydraulic cylinder adjustment of the roller spacing allows for precise control of the roller spacing, ensuring tight bonding and uniform rolling between fibers, improving the filtration performance and strength of the needle-punched felt. A stable and uniform rolling process ensures that the needle-punched felt has good filtration performance and strength, improving product quality, adapting to multi-layer rolling processes, improving overall processing quality, and better leveraging the advantages of needle-punched felt.

[0015] 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.

[0016] Please see Figure 1-3 This utility model provides a fiber-laminated needle-punched felt processing device, including two support plates 1, which are arranged vertically symmetrically. Hydraulic cylinders 2 are symmetrically fixedly connected between the inner sidewalls of the two support plates 1. A frame 3 is fixedly connected at the center of the inner sidewall of the support plate 1. A servo motor 5 is fixedly connected to the outer sidewall of the frame 3, and the output end of the servo motor 5 passes through the sidewall of the frame 3. A grooved roller 4 is fixedly connected to the output end of the servo motor 5. The other end of the grooved roller 4 is connected to the inner wall of the frame 3 in a rotatable connection. A pressure plate 6 is attached to the sidewall of the grooved roller 4, and the inner sidewalls of the two pressure plates 6 are attached to each other.

[0017] A concave frame 7 is fixedly connected to the side wall of the bottom support plate 1. A bracket 8 is fixedly connected to the center of the upper surface of the concave frame 7. A small round roller 9 is rotatably connected between the inner side walls of the bracket 8. The upper surface of the small round roller 9 is in contact with the lower surface of the bottom pressure plate 6.

[0018] The sidewall of the pressure plate 6 is symmetrically provided with protrusions, and the outer ring wall of the grooved roller 4 is symmetrically provided with grooves. The protrusions of the pressure plate 6 are in contact with the grooves on the sidewall of the grooved roller 4.

[0019] There are four hydraulic cylinders 2, which are arranged symmetrically.

[0020] During the processing of fiber-laminated needle-punched felt, the hydraulic cylinder 2 is used to raise and lower the layers, adjusting the gap between the two side frames 3. Then, the needle-punched felt layer is placed between the pressure plates 6. The needle-punched felt layer adopts a four-layer design, with the bottom fiber layer being a PTFE fiber layer and the upper layer being a PTFE base fabric. The pressure plates 6 are then placed between the grooved rollers 4. The protrusions on the surface of the pressure plates 6 interlock with the grooves of the grooved rollers 4 to maintain the stability of the upper and lower pressure plates 6 and prevent displacement during rolling. The grooved rollers 4 are driven to rotate by the servo motor 5 to perform the first layer rolling process. Then, the gap is adjusted again by the hydraulic cylinder 2. Finally, a layer of PTFE fiber is laid on the upper surface of the base fabric. The TFE fiber layer is bonded into a felt, and then a thin P84 fiber layer is attached to its surface. During the operation, it needs to be rolled multiple times, and some materials are in the form of threads. Adhesive is also applied. During the rolling process, the pressure plate 6 is used to clamp and fix it to ensure the vertical symmetry of the grooved rollers. At the same time, the operator cooperates and slowly feeds the pressure plate 6 with the rotation of the servo motor 5 to ensure that the pressure plate 6 enters the grooved rollers 4 stably for another rolling process. As the pressure plate 6 is fed in, a bracket 8 is set at the other end. The bracket 8 supports a small roller 8, which lifts the bottom of the pressure plate 6. The above operation completes the fiber-laminated needle-punched felt processing.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
