Description

Technical Field

[0001] The utility model relates to the field of calendering processing technology for butyl rubber cloth, in particular to a pre-processing automatic preheating device for butyl rubber cloth with special performance. Background Art

[0002] Butyl rubber is a synthetic rubber raw material formed by the copolymerization of isobutylene and a small amount of conjugated hydrocarbon olefins. It has good stability, air tightness and insulation. Its air permeability is only 1 / 7 of that of natural rubber. Therefore, in order to utilize the special properties of butyl rubber and solve the integration of butyl rubber with other base fabric materials to achieve effective special properties, it is necessary to solve the precise control of ambient temperature during the processing process.

[0003] In the existing technology, the temperature difference between the pressing point of the base cloth and the butyl special performance rubber is too large. The base cloth temperature in the original process is between 10 degrees Celsius and 30 degrees Celsius (basically covering the ambient temperature of the four seasons), and is directly pressed with the butyl special rubber film at a temperature of 100 degrees Celsius to 110 degrees Celsius, resulting in poor peeling performance between the rubber and the cloth.

[0004] Therefore, we propose an automatic preheating device for processing special-performance butyl rubber cloth. Utility Model Content

The support plate 12 is fixedly mounted on the lower part of the inner outer surface of the support frame 2. The two groups of transmission boxes 10 are fixedly mounted on the left and right ends of the outer surface of the upper end of the top plate 3. The dual-output shaft motor 8 is fixedly mounted in the middle of the outer surface of the upper end of the top plate 3. The two groups of driving shafts 9 are connected to the outer surface of one end of the output shaft of the dual-output shaft motor 8, and the end of the driving shaft 9 away from the dual-output shaft motor 8 extends into the transmission box 10; the worm 15 and the worm wheel 16 are both located inside the transmission box 10, the upper end of the ball screw 11 extends into the transmission box 10, the worm 15 is fixedly mounted on the outer wall of the end of the driving shaft 9 away from the dual-output shaft motor 8, and the worm wheel 16 is located on one side outer surface of the worm 15; the worm wheel 16 is fixedly mounted on the outer wall of the top of the ball screw 11, the ball nut 13 is located on the outer wall of the ball screw 11, and the connecting block 1 4 is fixedly installed between the outer surface of one side of the ball nut 13 and the outer surface of one end of the infrared heating plate 5, and the lower end of the ball screw 11 is connected to the support plate 12; a coupling is provided between the driving shaft 9 and the dual-output shaft motor 8, and the outer surface of one end of the driving shaft 9 is fixedly connected to the outer surface of one end of the output shaft of the dual-output shaft motor 8 through the coupling, a sealed bearing is provided between the driving shaft 9 and the transmission box 10, and the driving shaft 9 is rotatably connected to the transmission box 10 through the sealed bearing; sealed bearings are provided between the ball screw 11 and the transmission box 10 and the top plate 3, and the ball screw 11 is rotatably connected to the transmission box 10 and the top plate 3 through the sealed bearings, the ball nut 13 and the outer wall of the ball screw 11 are threadedly connected, a sealed bearing is provided between the ball screw 11 and the support plate 12, and the ball screw 11 is rotatably connected to the support plate 12 through the sealed bearing, and the outer surface of one side of the worm 15 is meshed with the outer surface of one side of the worm wheel 16.

[0027] It should be noted that the present invention is an automatic preheating device for processing special performance butyl rubber cloth. The infrared heating plate 5 is set before the rubber base cloth enters the position before being pressed with the butyl rubber. The base cloth is irradiated and heated from top to bottom. The base cloth is automatically heated during operation to increase the base cloth temperature to 70-80°C, which is close to the calendering temperature of 100-110°C of the special butyl rubber. The infrared heating plate 5 adopts a plurality of groups of infrared heating tubes to form a collective heating plate. The temperature of each group is independently controlled and can be adjusted according to the change of ambient temperature, so that the temperature of the base cloth when entering the butyl special rubber for pressing reaches above 70 to 80 degrees, which solves the problem of excessive temperature difference between the pressing point of the base cloth and the butyl special performance rubber. The base cloth temperature of the original process is between 10 degrees and 30 degrees (basically covering the ambient temperature of the four seasons), while the present invention directly increases the base temperature to 70 to 80 degrees, and then directly presses with the butyl special rubber adhesive at a temperature of 100 to 110 degrees. The sheets are pressed together to achieve the best fusion at high temperature. After the butyl special rubber molecular chain at high temperature is fully opened, it is fully integrated with the colloid in the base fabric, which enhances the peeling performance between the glue and the cloth. The base fabric is preheated to heat the base fabric fibers and the colloid in the fibers, open the fiber and colloid molecular chains, and wait for the special performance rubber at high temperature to be pressed together, thereby extending the service life of the rubber cloth; the height adjustment component 4 is set, and the operation of the dual-output shaft motor 8 drives the two sets of driving shafts 9 to rotate, and the driving shaft 9 drives the worm 15 to rotate. The worm 15 and the worm gear 16 are engaged with each other. The worm 15 drives the ball screw 11 to rotate through the worm gear 16. The ball nut 13 and the ball screw 11 are threadedly connected. Therefore, the rotation of the ball screw 11 can drive the ball nut 13 to rise and fall. The ball nut 13 drives the infrared heating plate 5 to rise and fall through the connecting block 14, thereby adjusting the distance between the infrared heating plate 5 and the cloth to improve applicability.
