Abstract
Description
Technical Field
[0001] The utility model relates to the field of battery diaphragm production lines, in particular to a split film guide roller. Background Art
[0002] The film guide roller in the battery separator production line is usually a stainless steel roller. There are acids and alkalis in the production environment of battery separators. Stainless steel rollers are not resistant to acids and alkalis and are easily corroded and damaged, so they need to be replaced frequently. They are also prone to generating static electricity, which makes the battery separator easily adsorbed and difficult to separate from the film guide roller. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a split film guide roller which is not easy to be damaged, is not easy to generate static electricity, has good self-lubrication and is low in cost.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a split film guide roller, which is characterized in that it includes: a PEEK outer tube, a steel inner tube, a left mounting shaft, a right mounting shaft, a left-spinning cover, and a right-spinning cover, the left mounting shaft is located on the outside of the left-spinning cover and is coaxially connected to the left-spinning cover, the inside of the left-spinning cover is coaxially provided with a left stud section, the left mounting shaft, the left-spinning cover, and the left stud section are made of PEEK as a whole, the right mounting shaft is located on the outside of the right-spinning cover and is coaxially connected to the right-spinning cover, and the inside of the right-spinning cover is coaxially provided with a left stud section. A right stud section is provided, and the right mounting shaft, right screw cap, and right stud section are made of PEEK in one piece. The steel inner tube is coaxially assembled with interference fit and inserted into the PEEK outer tube. The two ends of the steel inner tube are aligned with the two ends of the PEEK outer tube. Internal threads are respectively processed in the two ends of the steel inner tube. The left stud section and the right stud section are respectively screwed into the ports of the steel inner tube on their respective sides until the left screw cap and the right screw cap respectively abut against the two ends of the steel inner tube, and the outer ring walls of the left screw cap and the right screw cap are respectively flush with the outer wall of the PEEK outer tube.
[0005] Furthermore, the aforementioned split film guide roller, wherein: a left sealing groove is respectively provided on the two opposite surfaces of the left rotating cover and the left end of the PEEK outer tube, the two left sealing grooves are arranged oppositely, and a sealing ring is provided between them, and a right sealing groove is respectively provided on the two opposite surfaces of the right rotating cover and the right end of the PEEK outer tube, the two right sealing grooves are arranged oppositely, and a sealing ring is also provided between them.
[0006] Furthermore, in the aforementioned split film guide roller, the steel inner tube is a seamless steel tube.
[0007] Furthermore, in the aforementioned split film guide roller, the sealing ring is a PEEK sealing ring.
[0008] The advantages of the present invention are as follows: since the PEEK outer tube, left mounting shaft, left rotary cover, right mounting shaft and right rotary cover exposed to the outside of the split film guide roller are all made of PEEK material, the split film guide roller has the characteristics of acid and alkali resistance, is not easy to generate static electricity, and has good self-lubrication, so that it can pull the diaphragm well. In addition, if the entire film guide roller is made of PEEK, it will greatly increase the cost, so a hollow PEEK outer tube is provided to reduce the amount of PEEK, and a steel inner tube is installed in the PEEK outer tube to increase the weight and rigidity of the roller, so that the roller is not easy to bend and produce deflection, and at the same time, the weight of the roller can meet the requirements of the battery diaphragm production line, so that the battery diaphragm can maintain a certain tension under the guide tension of the film guide roller; when the left mounting shaft or the right mounting shaft is damaged, it can also be replaced separately, saving maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
