Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to an assembled rubber roller. Background Art

[0002] Rubber rollers are roll-shaped products made of a metal or other material core covered with vulcanized rubber. They can be classified in various ways, such as by application: papermaking rubber rollers, dyeing and printing rubber rollers, printing rubber rollers, rice hulling rubber rollers, metallurgical rubber rollers, and mimeograph rubber rollers; by surface morphology: flat rollers and patterned rubber rollers; and by material: butyl rubber rollers, nitrile rubber rollers, polyurethane rubber rollers, and silicone rubber rollers.

[0003] There is a Chinese patent application number CN202111682912.8, which is a length-adjustable assembled textile rubber roller. It belongs to the field of textile equipment technology and is used to solve the technical problem that the existing textile rubber roller cannot freely adjust the length and has a small scope of application. It includes multiple splicing tubes, the outer side of the splicing tubes is provided with a plurality of slide grooves, the slide grooves are provided with an arc-shaped plate, the interior of the splicing tubes is provided with a plurality of sliding mechanisms, the slide grooves are provided with a locking mechanism, the inner side of the end of the arc-shaped plate away from the locking mechanism is provided with a groove, the side end of the groove is provided with two locking grooves, and the groove is provided with an unlocking mechanism; the present invention can control the length of the textile rubber roller by controlling the number of splicing tubes, and has a wider range of use; the splicing seams are not on the same cross-section, which prevents wrinkles in the cloth and improves the quality of the finished product; the two splicing tubes can be quickly and conveniently assembled and disassembled, the operation is simple, and the connection is stable. When not assembled, the arc plate overlaps with the slide groove, the splicing tube is small in size, and is convenient for storage and transportation.

[0004] The assembled textile rubber roller is relatively complex in structure due to the inclusion of multiple components such as splicing tubes, chutes, curved plates, sliding mechanisms, locking mechanisms, and unlocking mechanisms, which may increase manufacturing and assembly costs and also increase maintenance difficulties.

[0005] Therefore, we propose a kind of assembled rubber roller, in order to solve the problem raised in above-mentioned. Utility Model Content

[0006] The present invention aims to provide an assembled rubber roller to solve the problem in the above-mentioned background art that the assembled textile rubber roller comprises a plurality of assembled tubes, chutes, curved plates, sliding mechanisms, locking mechanisms, and unlocking mechanisms, resulting in a relatively complex structure, which may increase the cost of manufacturing and assembly and increase the difficulty of maintenance.

[0011] Preferably, a positioning rod is slidably connected to the interior of the storage cavity, and a tension spring is fixedly connected between the positioning rod and the cavity.

[0012] With this technical solution, the positioning rod slides within the storage cavity under the action of a tension spring and extends into the positioning slot, thereby securing the fixed block to the fixed shaft. The tension spring provides the necessary elastic force and reset function, allowing the positioning rod to automatically return to its initial position.

[0019] 2. Through the fixed shaft and fixed block, the fixed shaft and the fixed block are slidably connected, which can be quickly disassembled and installed.

[0020] 3. Through the provided positioning groove, storage cavity, positioning rod and tension spring, the positioning rod can slide in the storage cavity under the action of the tension spring, extend into the positioning groove, and be slidably connected with the positioning groove, thereby achieving fixation between the fixed block and the fixed shaft.

[0021] 4. Through the provided placement cavity, limit rod and reset spring, pulling the limit rod can drive the reset spring to contract, loosening the limit rod, and the reset spring can drive the limit rod to reset, so that the limit rod can press against the positioning rod for preliminary positioning connection.

[0022] 5. By providing the threaded groove and locking screw sleeve, when the limiting rod extends to the outside of the fixed shaft, the locking screw sleeve is threadedly connected to the limiting rod through the threaded groove, thereby facilitating locking of the limiting rod.
