Description

Technical Field

[0001] This utility model relates to the field of rubber-coated roller technology, and in particular to a rubber-coated roller body structure with adjustable length. Background Technology

[0002] Rubber-coated rollers are rollers with a core made of metal or other materials covered with a layer of rubber or polymer material. They are widely used in various fields of industrial production, such as printing, papermaking, textiles, plastics processing, and logistics transportation. The core function of rubber-coated rollers is to provide specific physical and chemical properties through the outer coating material to meet different process requirements. Rubber-coated rollers have advantages such as significantly improving the wear resistance of the roller, extending its service life, absorbing vibration, reducing equipment operating noise, improving operating comfort, increasing friction to prevent material slippage, and protecting fragile materials from damage. Therefore, rubber-coated rollers are widely used in many fields. However, existing rubber-coated rollers cannot adjust their overall width according to the length of the external device, which limits their mobility. Furthermore, they are relatively long after use, making them inconvenient for users to store and clean. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-6 As shown, this embodiment provides a length-adjustable rubber-coated roller structure, including splicing rollers 1, with connecting components 2 for connecting the splicing rollers 1 between them. A connecting plate 3 is fixedly installed at one end inside both sides of the splicing rollers 1, and a connecting shaft 4 for connecting to an external device is fixedly installed on one side of the connecting plate 3. Both ends of the splicing rollers 1 are provided with snap-fit ​​holes 5 arranged in a circumferential array. The connecting components 2 are snapped into one end of the splicing rollers 1 through the snap-fit ​​holes 5. In use, first select an appropriate number of splicing rollers 1 and connecting components 2 according to the actual use. At this time, there are two splicing rollers 1 with connecting plates 3 and connecting shafts 4 installed, and they are set at both ends of the splicing structure. The splicing rollers 1 are connected through the connecting components 2, thereby completing the assembly of this mechanism. It is used to connect to external equipment through the connecting shafts 4. After use, the splicing rollers 1 can be disassembled through the connecting components 2, which facilitates cleaning and storage by the user.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 2 and Figure 4As shown, the connecting assembly 2 includes a connecting roller 201. Both sides of the connecting roller 201 are fixedly mounted with snap-fit ​​posts 202 in a circumferential array. The connecting roller 201 is snapped onto one end of the splicing roller 1 via the snap-fit ​​posts 202 and snap-fit ​​holes 5. Rubber pads 6 are fixedly mounted on the exterior of both the connecting roller 201 and the splicing roller 1. The rubber pads 6 have the same thickness. During use, the snap-fit ​​posts 202 and snap-fit ​​holes 5 can snap the connecting roller 201 onto one end of the splicing roller 1, thereby improving positioning accuracy and facilitating splicing. The rubber pads 6 increase the friction between the surfaces of the splicing roller 1 and the connecting roller 201 while preventing damage to the goods, thus enabling the transport of goods.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 5 and Figure 6 As shown, a connecting cylinder 203 is fixedly installed inside the connecting roller 201. The connecting cylinder 203 extends to both sides of the outer surface of the connecting roller 201. Rotating grooves 204 are circumferentially formed on both sides of the connecting roller 201. Rotating slots 205 are formed on both sides of the rotating grooves 204. A rotating shaft 206 is rotatably engaged in the rotating grooves 204. Both ends of the rotating shaft 206 are rotatably engaged in the rotating slots 205. A locking rod 207 is fixedly installed on the outside of the rotating shaft 206. A locking protrusion is provided at the other end of the locking rod 207. Locking grooves 7 are circumferentially arrayed at both ends of the splicing roller 1. The locking protrusion on the locking rod 207 cooperates with the locking groove 7, and one side of the locking groove 7 is inclined. One end of the locking rod 207 is fixedly installed on one side. There is a snap-fit ​​spring 208, the other end of which is fixedly connected to the outside of the connecting cylinder 203. During the process of snapping the snap-fit ​​post 202 into the snap-fit ​​hole 5, the snap-fit ​​rod 207 moves in the splicing roller 1 until one end of the snap-fit ​​rod 207 is snapped into the snap-fit ​​groove 7. Under the action of the snap-fit ​​spring 208, the snap-fit ​​rod 207 can be snapped into the snap-fit ​​groove 7, thereby completing the connection between the splicing roller 1 and the connecting roller 201. When disassembling, since one side of the snap-fit ​​groove 7 is inclined, when the user pulls it with force, the snap-fit ​​rod 207 rotates under the action of the rotating shaft 206, causing one end of the snap-fit ​​rod 207 to be pushed away from the snap-fit ​​groove 7 until the splicing roller 1 and the connecting roller 201 are separated, thus facilitating the user to clean and store it.

[0023] In use, this invention involves first selecting an appropriate number of splicing rollers 1 and connecting components 2 based on actual usage. At this point, two splicing rollers 1, each equipped with a connecting plate 3 and a connecting shaft 4, are positioned at both ends of the splicing structure. The connecting roller 201 is secured to one end of the splicing roller 1 via the locking pin 202 and locking hole 5, thereby improving positioning accuracy and facilitating splicing. During the process of locking the locking pin 202 into the locking hole 5, the locking rod 207 moves within the splicing roller 1. Until one end of the locking rod 207 is engaged in the locking groove 7, the locking spring 208 can hold the locking rod 207 in the locking groove 7, thus completing the connection between the splicing roller 1 and the connecting roller 201. When disassembling, since one side of the locking groove 7 is inclined, when the user pulls it, the locking rod 207 rotates under the action of the rotating shaft 206, causing one end of the locking rod 207 to be pushed away from the locking groove 7 until the splicing roller 1 and the connecting roller 201 are separated, thus facilitating cleaning and storage for the user.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
