Description

Technical Field

[0001] This utility model relates to a glass fiber needle-punched felt pressing device, belonging to the field of glass fiber needle-punched felt pressing technology. Background Technology

[0002] Glass fiber needle-punched felt is a filter material with a reasonable structure and good performance. It can be used in the automotive industry for sound insulation, sound absorption, vibration reduction, and flame retardancy, and can also be used in industrial filtration and high-temperature flue gas filtration. Multilayer needle-punched felt is a filter material with a reasonable structure and good performance. It is made of glass fiber as raw material. The short-cut glass fiber felt after being combed is needle-punched with needles. The fibers between the glass fibers in the felt layer and between the glass fibers in the felt layer and the reinforcing glass fiber base cloth are entangled by mechanical methods, and the fiber web is reinforced to make a felt-like non-woven filter material. In the production process of multilayer needle-punched felt, a pressing device is needed to press the multilayer needle-punched felt together.

[0003] Existing technologies also include pressing devices for multi-layer needle-punched felt. However, there are some inconveniences in the pressing process. First, the needle-punched felt cannot be conveyed simultaneously during the pressing process. The conveying equipment needs to be paused before the pressing device can complete the pressing. Second, since multi-layer needle-punched felt needs to be pressed, the stacked needle-punched felt needs to be pulled when the multi-layer needle-punched felt is being conveyed. Existing technologies generally use a drive roller for transmission, which drives the entire layer of needle-punched felt by driving the needle-punched felt attached to the side of the drive roller. This driving method results in different tensions between the multi-layer needle-punched felt, leading to poor pressing effect and even slippage between different layers.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a glass fiber needled felt pressing device that can simultaneously pull the upper and lower surfaces of multi-layer glass fiber needled felt, resulting in better pressing effect; at the same time, it can change the edge conveying of the needled felt into pressing, thereby improving work efficiency.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A glass fiber needled felt pressing device includes a frame, with a pressing mechanism at each of the two ends of the lower side of the frame, and the multi-layer glass fiber needled felt is driven between the two pressing mechanisms. A pulling and pressing device is provided between the two pressing mechanisms. The pulling and pressing device includes two traction rollers arranged vertically, and the traction rollers are fixedly installed on the first rotating shaft. Connecting arms are provided at both ends of the first rotating shaft. The first rotating shaft is rotatably mounted at one end of the connecting arm, and the other end of the connecting arm is rotatably mounted on the fixed side plate. The upper end of the fixed side plate is fixed to the top of the frame. The two traction rollers are driven by a drive mechanism to rotate synchronously.

[0007] Furthermore, the drive mechanism includes two meshing transmission gears, which are fixed on a second rotating shaft. A second synchronous pulley is also fixed on the second rotating shaft, and a first synchronous pulley is fixed on a first rotating shaft. The first synchronous pulley and the second synchronous pulley are driven by a synchronous belt.

[0008] Furthermore, the other end of the connecting arm is rotatably mounted on the second rotating shaft, and the outer end of the second rotating shaft is mounted on the fixed side plate.

[0009] Furthermore, a second tension spring is connected to the connecting arm that is connected to the upper traction roller, and the upper end of the second tension spring is hung on the frame.

[0010] Furthermore, one of the transmission gears is driven by a drive gear, which is connected to the drive shaft of the drive motor.

[0011] Furthermore, the pressing device includes a lower pressure roller and an upper pressure roller located above the upper pressure roller. The lower pressure roller is rotatably mounted on a fixed frame, and the upper pressure roller is mounted on an elastic support.

[0012] Furthermore, an installation shaft is installed at the upper end of the elastic bracket, the installation shaft is inserted into the elastic bracket, and a compression spring is provided inside the elastic bracket.

[0013] Furthermore, retaining rings are provided at both ends of the lower pressure roller.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The pulling and pressing device pulls the multi-layer glass fiber needle-punched felt forward through two traction rollers arranged vertically. The two traction rollers are driven by meshing transmission gears. The transmission gears rotate synchronously with the second synchronous wheel, and the traction rollers rotate synchronously with the first synchronous wheel, thus ensuring that the upper and lower traction rollers rotate synchronously. This allows the upper and lower surfaces of the multi-layer glass fiber needle-punched felt to be pulled synchronously, and the traction rollers also play a pressing role, resulting in a better pressing effect.

[0015] Multi-layer glass fiber needled felt is horizontally input from the input side clamping device and horizontally output from the output side clamping device. In the two clamping devices, the upper pressure roller presses against the needled felt conveyed by the lower pressure roller, which plays a clamping role, making the needled felt pressurized while being conveyed, thus improving work efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this utility model provides a glass fiber needle-punched felt pressing device, including a frame 18, with a pressing mechanism provided at each of the two ends of the lower side of the frame 18, and the multi-layer glass fiber needle-punched felt is driven between the two pressing mechanisms. A pulling and pressing device is provided between the two pressing mechanisms. The pulling and pressing device includes two traction rollers 6 arranged vertically, and the traction rollers 6 are fixedly installed on the first rotating shaft 11. The first rotating shaft 11 has connecting arms 10 at both ends. The first rotating shaft 11 is rotatably mounted on one end of the connecting arm 10, and the other end of the connecting arm 10 is rotatably mounted on the fixed side plate 13. The upper end of the fixed side plate 13 is fixed to the top of the frame 18. The two traction rollers 6 are driven by a drive mechanism to rotate synchronously.

[0021] The drive mechanism includes two meshing transmission gears 12, which are fixed on a second rotating shaft 19. A second synchronous pulley 8 is also fixed on the second rotating shaft 19. A first synchronous pulley 7 is fixed on a first rotating shaft 11. The first synchronous pulley 7 and the second synchronous pulley 8 are driven by a synchronous belt 9.

[0022] The other end of the connecting arm 10 is rotatably mounted on the second rotating shaft 19, and the outer end of the second rotating shaft 19 is mounted on the fixed side plate 13.

[0023] A second tension spring 15 is connected to the connecting arm 10, which is connected to the upper traction roller 6. The upper end of the second tension spring 15 is hung on the frame 18.

[0024] One of the transmission gears 12 is driven by a drive gear (not shown in the figure), which is connected to the drive shaft of a drive motor (not shown in the figure).

[0025] The pressing device includes a lower pressure roller 1 and an upper pressure roller 2 located above the upper pressure roller 2. The lower pressure roller 1 is rotatably mounted on a fixed frame, and the upper pressure roller 2 is mounted on an elastic support 3. The upper pressure roller 2 presses against the needle-punched felt conveyed by the lower pressure roller 1, thus achieving a pressing effect.

[0026] The upper end of the elastic bracket 3 is equipped with an installation shaft 4, which is inserted into the elastic bracket 3. A compression spring 5 is provided inside the elastic bracket 3.

[0027] The lower pressure roller 1 has retaining rings 101 at both ends. After the multi-layer glass fiber needle-punched felt is conveyed to the lower pressure roller 1, the retaining rings 101 block the two sides of the multi-layer glass fiber needle-punched felt, so that the two sides of the needle-punched felt are aligned.

[0028] A first guide wheel 16 is provided on the front side of the conveying device on the input side, and a second guide wheel 17 is provided on the rear side of the conveying device on the output side.

[0029] The specific working principle of this utility model: Multi-layer glass fiber needled felt is horizontally input from the input side pressing device and horizontally output from the output side pressing device. In the two pressing devices, the upper pressure roller 2 presses against the needled felt conveyed by the lower pressure roller 1, which plays a pressing role, making the needled felt pressurized while being conveyed, thus improving work efficiency.

[0030] A pulling and pressing device is provided between the two pressing mechanisms. The pulling and pressing device pulls the multi-layer glass fiber needle-punched felt forward through two traction rollers 6 arranged vertically. The two traction rollers 6 are driven by meshing transmission gears 12. The transmission gears 12 rotate synchronously with the second synchronous wheel 8, and the traction rollers 6 rotate synchronously with the first synchronous wheel 7, thereby ensuring that the upper and lower traction rollers 6 rotate synchronously, so that the upper and lower surfaces of the multi-layer glass fiber needle-punched felt are pulled synchronously. Moreover, the traction rollers 6 also play a pressing role, making the pressing effect better.
