Description

Technical Field

[0001] This utility model relates to the technical field of film winding machines, specifically, to a heating and bonding device for RO membranes and filter cartridges. Background Technology

[0002] Existing RO membrane filter cartridges consist of an RO membrane filter cartridge tube and an RO membrane wound around the RO membrane filter cartridge tube as an axis. In existing winding equipment, the end of the guide cloth is typically fed to the filter cartridge tube, and then the filter cartridge tube and the guide cloth are clamped between an ultrasonic welding machine and an upper pressure plate, so that the filter cartridge tube and the guide cloth are welded together. For example, Chinese patent document CN105479732A discloses an RO membrane center tube and gauze bonding mechanism, which includes a winding mechanism for fixing and rotating the RO membrane center tube and an ultrasonic welding mechanism for ultrasonically welding the gauze and the RO membrane center tube.

[0003] However, this ultrasonic welding mechanism can only perform welding by moving up and down. But for filter tubes of different lengths, after the filter tube is fixed on the winding mechanism, some positions of the ultrasonic welding mechanism cannot correspond to the filter tube. This means that after the ultrasonic welding mechanism rises, it can only weld a part of the filter tube, but cannot weld the other part. This makes the equipment less adaptable. Moreover, the ultrasonic welding equipment is relatively expensive, which makes the equipment cost high. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a heating and bonding device for RO membrane and filter tube to solve the problems in the existing technology.

[0017] Combination Figures 1 to 3 The RO membrane and filter tube heating and bonding device shown includes a support base 1, a left-right movable support seat 3 mounted on the side of the support base 1, a liftable heater mounting bracket 7 provided on the upper end of the support seat 3, a heater 9 mounted on the upper end of the heater mounting bracket 7, a heating rod installed inside the heater 9, the upper end surface of the heater 9 being the heating surface, and the heating rod contacting the heating surface; in this embodiment, the heater 9 and heating rod can be raised and lowered, so that the heating surface presses the guide cloth 18 onto the surface of the filter tube 19 for heating, causing the guide cloth 18 to melt and bond to the filter tube 19, thus completing the bonding. Moreover, the support base 3 can drive the heater mounting bracket 7 to move left and right, and for filter tubes 19 of different lengths, the position of the heater 9 can be adjusted so that the heating surface can better complete the bonding process, making it more adaptable. Compared with the ultrasonic welding structure in the prior art, the equipment cost is also relatively lower.

[0018] Specifically, the heating surface is a concave arc-shaped heating groove 10. The filter tube 19 can be placed in the arc-shaped heating groove 10. After the arc-shaped heating groove 10 is raised by the heater mounting bracket 7, the filter tube 19 and the guide cloth 18 located below the filter tube 19 are placed in the arc-shaped heating groove 10, so that the guide cloth 18 can contact the surface of the filter tube 19. Moreover, the arc-shaped heating groove 10 can better contact and heat the guide cloth 18, so that the guide cloth 18 can quickly melt and adhere to the filter tube 19.
