[0002] Glass fiber felt is a non-woven fabric product made of glass fiber through a wet-laid web process. It has good insulation, heat insulation, fire resistance, and corrosion resistance. In the process of producing glass fiber felt, the glue on the surface of the glass fiber felt needs to be dried. After drying, the temperature of the glass fiber felt after drying needs to be lowered to improve its quality and performance and prevent it from thermal aging and deformation.

[0003] When the existing cooling device is in use, the hot glass fiber felt is wound around the cooling roller, and the high-temperature glass fiber felt continuously exchanges heat with the cooling roller, thereby reducing the temperature of the glass fiber felt and achieving cooling. However, since the heat exchange area between the glass fiber felt and the cooling roller is small, in order to achieve a good cooling effect, the number of cooling rollers needs to be increased accordingly. The existing glass fiber felt is folded back and forth between multiple groups of cooling rollers, resulting in the installation position of some cooling rollers being relatively high, making it difficult to conveniently install the glass fiber felt on the cooling roller, and it is difficult to meet the use requirements.

DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-5 As shown, a cooling device for glass fiber mat production includes an outer barrel 1, and the two ends of the outer barrel 1 are respectively provided with extension ends 2 that penetrate the interior of the outer barrel 1, and the interior of the outer barrel 1 is provided with a center tube 3, and the outer surface of the center tube 3 is connected to the inner surface of the outer barrel 1 through a spiral plate 4, and a cooling channel is formed between the spiral plate 4 and the outer barrel 1 and the center tube 3, and the two ends of the cooling channel are respectively connected with the extension ends 2 at the two ends of the outer barrel 1. It also includes symmetrically arranged support seats 5, and the extension ends 2 at the two ends of the outer barrel 1 are respectively rotatably connected to the support seats 5, and also includes a motor 6, and the output end of the motor 6 and one of the extension ends 2 in the outer barrel 1 are respectively provided with pulleys 7, and the two pulleys 7 are connected to each other. The transmission is transmitted by a belt 8, and extrusion mechanisms are respectively arranged on both sides of the two support seats 5, and the extrusion mechanism includes a rocker arm 9, the lower end of the rocker arm 9 is located in the middle position of the support seat 5 and is rotatably connected to the support seat 5, and the upper end of the rocker arm 9 is provided with a mounting groove 10, and also includes a hydraulic cylinder 12, the bottom end of the hydraulic cylinder 12 is located at the bottom position of the support seat 5 and is rotatably connected to the support seat 5, the output end of the hydraulic cylinder 12 is located in the middle position of the rocker arm 9 and is rotatably connected to the rocker arm 9, and also includes an extrusion roller 13, the two ends of the extrusion roller 13 are respectively arranged in two mounting grooves 10 located on the same side of the two support seats 5, and the extrusion roller 13 is rotatably connected to the rocker arm 9 through the mounting groove 10.

[0020] The extension ends 2 at both ends of the outer barrel 1 are respectively connected to the water inlet pipe and the water outlet pipe, and the extension ends 2 are rotatably connected to the water inlet pipe and the water outlet pipe respectively. The water inlet pipe enters the interior of the outer barrel 1 through one of the extension ends 2, and the cooling water flows to the other extension end 2 through the cooling channel and is discharged from the outer barrel 1 through the extension end 2. The outer wall of the outer barrel 1 is in direct contact with the glass fiber felt 18, and heat exchange is achieved with the cooling water in the outer barrel 1, thereby reducing the temperature of the glass fiber felt 18 and cooling the glass fiber felt 18. The central tube 3 can reduce the volume of the cooling channel in the outer barrel 1, reduce water consumption, and ensure that the inner wall of the outer barrel 1 has sufficient contact with the cooling water.

[0021] A bearing 11 is disposed between the support base 5 and the extension end 2 of the outer barrel 1 to reduce the friction between the support base 5 and the extension end 2 .

[0022] The hydraulic cylinder 12 can control the swing of the rocker arm 9 by controlling the extension and retraction of its output end. When the output end of the hydraulic cylinder 12 is extended, the upper end of the rocker arm 9 moves toward the upper end of the outer barrel 1. When the output end of the hydraulic cylinder 12 is retracted, the upper end of the rocker arm 9 moves away from the upper end of the outer barrel 1. When the glass fiber felt 18 needs to be placed on the outer wall of the outer barrel 1, it is necessary to control the output end of the hydraulic cylinder 12 first. Then, when the glass fiber felt 18 passes through the outer barrel 1 from the bottom of the outer barrel 1, the output end of the hydraulic cylinder 12 is controlled to extend, and the glass fiber felt 18 is attached to the outer wall of the outer barrel 1 through the squeezing roller 13.

[0023] Working principle: By controlling the output end of the hydraulic cylinder 12 to retract, the distance between the squeezing roller 13 and the outer barrel 1 is increased, and then the glass fiber felt 18 passes through the bottom of the outer barrel 1. After the glass fiber felt 18 completely passes through the outer barrel 1, the output end of the hydraulic cylinder 12 is controlled to extend, and the squeezing roller 13 is driven by the rocker 9 to apply pressure to the glass fiber felt 18, so that the glass fiber felt 18 is attached to the outer wall of the outer barrel 1. At the same time, cooling water is continuously injected into and out of the outer barrel 1, and then the motor 6 is started. The motor 6 drives the outer barrel 1 to rotate through the pulley 7 and the belt 8, and through the extension end 2. During the rotation of the outer barrel 1, the outer wall of the outer barrel 1 and the glass fiber felt 18 achieve heat exchange, thereby reducing the temperature of the glass fiber felt 18 and achieving cooling of the glass fiber felt 18. , and during the movement of the glass fiber felt 18, the friction between the outer barrel 1 and the glass fiber felt 18 can be reduced through the active rotation of the outer barrel 1, and the squeezing roller 13 will also rotate with the glass fiber felt 18, which can effectively protect the glass fiber felt 18 and prevent it from friction and breakage, thereby improving product quality. Since the contact area between the glass fiber felt 18 and the outer barrel 1 can be increased by the squeezing roller 13, the number of outer barrels 1 can be reduced to achieve the same cooling effect, and the glass fiber felt 18 can enter the cooling device in a horizontal manner and leave the cooling device in a horizontal manner, so the cooling device can be paved on the ground, reducing the height of the cooling device, and making it easier for workers to place the glass fiber felt 18 on the cooling device.

[0024] Furthermore, follow-up friction rings 14 are respectively provided at both ends of the extrusion roller 13, and the two follow-up friction rings 14 are located between the two rocker arms 9. Active friction rings 15 that cooperate with the follow-up friction rings 14 are respectively provided at both ends of the outer barrel 1. When the outer barrel 1 rotates driven by the motor 6, the friction connection between the active friction ring 15 and the follow-up friction ring 14 can drive the two extrusion rollers 13 to rotate with the outer barrel 1. When there are no follow-up friction rings 14 and the active friction rings 15, there is a large friction force between the glass fiber felt 18 and the extrusion roller 13. The glass fiber felt 18 drives the extrusion roller 13 to rotate through the friction force. When there are follow-up friction rings 14 and the active friction rings 15, the friction between the glass fiber felt 18 and the extrusion roller 13 can be reduced, which is beneficial to improving the product quality of the glass fiber felt 18.

[0025] Furthermore, an abutment rod 16 is provided on one side of the rocker arm 9. When the follower friction ring 14 cooperates with the active friction ring 15, one end of the abutment rod 16 is located on the outer surface of the support seat 5. When the rocker arm 9 moves, when one end of the abutment rod 16 contacts the outer surface of the support seat 5, it indicates that the extrusion roller 13 reaches the predetermined position, and the output end of the hydraulic cylinder 12 stops extending. Through the support of the abutment rod 16 and the hydraulic cylinder 12, the stability of the extrusion roller 13 can be improved.

[0026] Furthermore, an abutment plate 17 is provided at one end of the abutment rod 16 close to the support seat 5, and the contact area between the abutment plate 17 and the support seat 5 is larger than the contact area between the abutment rod 16 and the support seat 5. The abutment plate 17 can increase the contact area with the support seat 5 relative to the abutment rod 16, thereby reducing the local pressure of the abutment rod 16 on the support seat 5 and improving the abutment stability between the abutment rod 16 and the support seat 5.

[0027] Furthermore, the interior of the central tube 3 is in a hollow state, and the weight of the cooling device can be reduced by the central tube 3.

[0028] The device can increase the heat exchange area between the glass fiber felt 18 and a single outer barrel 1 by providing the squeezing roller 13, thereby reducing the number of cooling rollers, and the squeezing roller 13 can make the direction of the glass fiber felt 18 when entering the cooling device and the direction when leaving the cooling device remain the same, so that there is no need to fold the glass fiber felt 18 back and forth between multiple cooling rollers, thereby reducing the height of the cooling device and improving the installation convenience of the glass fiber felt 18.
