Description

Technical Field

[0001] This utility model relates to the field of mesh fabric processing technology, specifically a mesh fabric impregnation device. Background Technology

[0002] In the process of impregnating mesh fabric with adhesive, traditional equipment typically uses guide rollers in fixed positions to control the immersion depth of the mesh fabric in the adhesive solution. However, the static impregnation method has significant drawbacks:

[0003] Poor uniformity of adhesive impregnation: When the mesh fabric passes through the static adhesive tank at a constant speed, due to local tension differences or limitations in adhesive flow, the impregnation depth in different areas of the fabric surface is easily inconsistent, resulting in local over-impregnation (excessive adhesive penetration) or under-impregnation (insufficient penetration), which affects the interlayer bonding strength of the composite material.

[0004] Low process adaptability: Fixed rollers cannot dynamically respond to changes in adhesive viscosity or fluctuations in fabric speed, making it difficult to optimize impregnation parameters to match the needs of different mesh fabric specifications.

[0005] While existing technologies attempt to improve uniformity by increasing the number of rollers or adjusting the adhesive tank structure, they have failed to address the core issue of dynamically and in real-time adjusting the impregnation depth. Therefore, there is an urgent need for a device capable of actively controlling the impregnation trajectory of the mesh fabric to achieve uniform penetration of the adhesive into the fiber gaps.

[0023] This utility model embodiment provides a mesh fabric impregnation device, such as... Figure 1-4 As shown, it includes a housing 11, an impregnation chamber 12, an inlet / outlet port 13, a circulation groove 14, a circulation pipe 15, a circulation channel 16, a circulation pump 17, a first drive shaft 18, a guide roller 19, a thermometer 20, a sliding groove 21, a sliding base 22, a second rotating shaft 23, a limiting roller 24, a rotating sleeve 25, a third drive shaft 26, a third drive block 27, a fourth drive shaft 28, and a fourth drive block 29.

[0024] like Figure 1-4 As shown, the outer casing 11 has an impregnation chamber 12. Both ends of the impregnation chamber 12 have inlet / outlet ports 13 and circulation slots 14. A circulation pipe 15 is fixedly connected to the circulation slot 14. A circulation channel 16 is opened in the circulation pipe 15. A circulation pump 17 is fixedly connected in the circulation channel 16. Two transmission roller sets are installed in the impregnation chamber 12. Several temperature measuring instruments 20 are fixedly installed on both sides of the impregnation chamber 12. Several sliding grooves 21 are opened on both sides of the impregnation chamber 12. Impregnation components are slidably installed in the sliding grooves 21. Drive components are installed on both sides of the sliding grooves 21. The drive components are used to drive the impregnation components to slide in the sliding grooves 21.

[0025] Different wetting components are arranged in opposite directions. The wetting component includes two sliding bases 22 and two second rotating shafts 23. The sliding bases 22 are slidably connected to the sliding grooves 21. The two ends of the second rotating shafts 23 are rotatably connected to the two sliding bases 22 respectively. A limiting roller 24 is fixedly sleeved on the outer circular surface of the second rotating shaft 23. Rotating sleeves 25 are rotatably sleeved on both ends of the second rotating shaft 23. The rotating sleeves 25 are rotatably connected to the drive component.

[0026] The drive assembly includes a third drive shaft 26 and a fourth drive shaft 28. A third drive block 27 is fixedly connected to the outer circular surface of the third drive shaft 26, and a fourth drive block 29 is fixedly connected to the outer circular surface of the fourth drive shaft 28. The rotating sleeve 25 is in rolling connection with the third drive block 27 and the fourth drive block 29 respectively.

[0027] It is worth noting that both the third drive block 27 and the fourth drive block 29 are elliptical, and the rotation angles of the third drive block 27 and the fourth drive block 29 differ by 90°. The ratio of the major axis to the minor axis of the third drive block 27 and the fourth drive block 29 is 2 to 1. When the third drive block 27 and the fourth drive block 29 rotate, they push the 23 to move up and down through the rotating sleeve 25.

The transmission roller group includes two first drive shafts 18 and two guide rollers 19. The guide rollers 19 are fixedly sleeved on the outer circular surface of the first drive shafts 18.

[0029] When the mesh fabric is impregnated with adhesive in this patent, firstly, the mesh fabric is fed into the impregnation chamber 12 from the inlet / outlet 13 at one end, and the first drive shaft 18 of the transmission roller group is started, so that the guide roller 19 rotates to drive the mesh fabric to move at a constant speed.

[0030] Then, the third drive shaft 26 and the fourth drive shaft 28 of the drive assembly are started, causing the third drive block 27 and the fourth drive block 29 to rotate. Through their elliptical structure and 90° phase difference, they drive the rotating sleeve 25 and the second drive shaft 23 to move up and down, thereby driving the limiting roller 24 to dynamically adjust the immersion depth of the mesh cloth in the adhesive.

[0031] At the same time, the circulation pump 17 is started to circulate the adhesive through the circulation channel 16 in the impregnation chamber 12 to maintain the uniformity of the adhesive, and the temperature of the adhesive is monitored in real time by the thermometer 20 to ensure that it is within the preset range.

[0032] Finally, after the mesh fabric is fully impregnated with adhesive, it is output from the inlet / outlet 13 at the other end, completing the impregnation process.
