Description

Technical Field

[0001] This utility model relates to the field of polyurethane roller technology, specifically a polyurethane roller. Background Technology

[0002] Polyurethane rollers are roller-shaped products made of polyurethane material. They are mainly used in various industrial and mechanical equipment. Polyurethane rollers have excellent properties such as high elasticity, wear resistance, oil resistance and compression resistance, and are suitable for working environments with high linear speed and high pressure.

[0003] For example, the Chinese authorized patent with announcement number CN219529560U (a polyurethane roller) includes: a rotating shaft with fixing parts at both ends, the rotating shaft also including fixing bolts, the fixing parts being connected to the rotating shaft by fixing bolts; a fixing ring, of which there are several, the fixing rings being disposed on the surface of the rotating shaft and located between the fixing parts; a contact ring, the contact rings being disposed around the outer periphery of the corresponding fixing rings; a spring, the spring being disposed between the fixing rings and the contact rings; and a rubber sleeve, the rubber sleeve being sleeved on the outer periphery of the contact rings. The beneficial effect of this utility model is that the elastic force of the spring applied to the contact rings makes the distance from the rotating shaft to the outer periphery of the contact rings variable, and when the roller contacts an object, it can change or recover at any time according to the shape of the object's surface.

[0004] However, the existing polyurethane rollers use friction or adhesive to fix the sleeve to the rotating body. When fixed by friction, the roller is prone to rotational deviation and slippage under stress, affecting the performance. When fixed by adhesive, it is inconvenient to disassemble and replace, resulting in poor flexibility. Therefore, these methods do not meet the current requirements. To address this, we have proposed a new polyurethane roller. Utility Model Content

[0005] The purpose of this utility model is to provide a polyurethane rubber roller to solve the problems mentioned in the background art. The rubber sleeve of the existing polyurethane rubber roller is fixed to the rotating body by friction or fixing glue. When fixed by friction, it is easy to experience rotational displacement and slippage under force, which affects the use effect. When fixed by fixing glue, it is inconvenient to disassemble and replace, resulting in poor flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane roller, comprising: a roller body, with stabilizing components at both ends of the roller body; the roller body includes a rotating body and a rubber sleeve, with the rubber sleeve covering the outside of the rotating body; a second limiting slot is provided on the outer surface of the rotating body, and multiple second limiting slots are provided and distributed in an equidistant array; a second limiting plate is provided on the inner wall of the rubber sleeve, and multiple second limiting plates are provided and inserted along the second limiting slots; a shaft connecting groove is provided on the center surface of both ends of the roller body, and an installation component is inserted into the inside of the shaft connecting groove.

[0007] Preferably, the stabilizing component includes a stabilizing disk with a through-hole groove at its center, and the stabilizing disk is fitted onto the outside of the mounting component through the groove. A force-bearing plate is provided on one side surface of the stabilizing disk, and hand-grip grooves are provided on both sides of the force-bearing plate.

[0008] Preferably, the stabilizing component further includes a threaded ring plate, which is located on the other side surface of the stabilizing disk. Threaded grooves are provided on the surfaces of both ends of the rotating body near the edges, and the threaded ring plate is threadedly connected to the threaded grooves.

[0009] Preferably, the mounting assembly includes a connecting shaft, the outer wall of which is provided with a first limiting plate, and the first limiting plate is thermally fused to the connecting shaft. Multiple first limiting plates are provided, and the inner walls of the connecting groove of the shaft are provided with first limiting slots, and the first limiting plate is inserted into the first limiting slot.

[0010] Preferably, threaded connection holes are provided on the upper surfaces of both ends of the first limiting plate, and bolt holes are provided on the outer wall of the rotating body. The bolt holes penetrate the rotating body, and a fixing bolt is inserted into one end of the bolt hole. The other end of the fixing bolt passes through the bolt hole and is threadedly connected to the threaded connection hole.

[0011] Preferably, the mounting assembly further includes a shaft head, which is mounted on one end of the connecting insert shaft, and one end of the shaft head is provided with a mounting shaft.

[0012] Preferably, the material of the rubber sleeve is polyurethane, and the material of the second limiting insert is also polyurethane.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets stabilizing components at both ends of the roller body and sets a second limiting plate on the inner wall of the rubber sleeve. When installing the rubber sleeve, the second limiting plate is inserted along the second limiting slot, which improves the stability of the connection between the rubber sleeve and the rotating body. It is not easy to deviate or slide when rotating, thus improving stability. Then, the stabilizing components are installed. The stabilizing plate is sleeved on the outside of the installation components through the sleeve groove, and the threaded ring plate is threadedly connected to the threaded groove to fix the stabilizing plate and the rotating body. At this time, the stabilizing plate also has a limiting effect on the end of the rubber sleeve, preventing the rubber sleeve from slipping off the rotating body and improving stability. It replaces the existing method of fixing with adhesive, which is convenient for disassembly and replacement, and improves convenience. The stabilizing plate further reinforces the first limiting plate, preventing it from slipping along the first limiting slot. This solves the problem that the rubber sleeve of the existing polyurethane rubber roller is fixed to the rotating body by friction or adhesive. When fixed by friction, it is easy to rotate and slide under force, which affects the use effect. When fixed by adhesive, it is inconvenient to disassemble and replace, resulting in poor flexibility.

[0015] (2) By setting the insertion shaft connecting groove on the center surface of both ends of the rotating body, the installation component is inserted into the insertion shaft connecting groove. When inserted, the connecting shaft is inserted into the insertion shaft connecting groove, and the first limiting plate is inserted into the first limiting slot to achieve the limiting effect. When the connecting shaft rotates, it drives the rotating body to rotate without rotational offset or slippage, thus improving the stability of rotation. The rotating body and the installation component are fixed by fixing bolts. The detachable installation component is easy to replace. Attached Figure Description

[0023] The mounting assembly 22 includes a connecting shaft 6, with a first limiting plate 8 on its outer wall. The first limiting plate 8 is heat-fused to the connecting shaft 6, and multiple first limiting plates 8 are provided. Each of the four inner walls of the shaft connecting groove 17 has a first limiting slot 7, and the first limiting plate 8 is inserted into the first limiting slot 7. Threaded connection holes 16 are provided on the upper surfaces of both ends of the first limiting plate 8. Bolt holes 18 are provided on the outer wall of the rotating body 3, penetrating the rotating body 3. A fixing bolt 19 is inserted into one end of the bolt hole 18, and the other end of the fixing bolt 19 passes through the bolt hole 18 and is threadedly connected to the threaded connection hole 16. The mounting assembly 22 also includes a shaft head 9, which is installed at one end of the connecting shaft 6. An mounting shaft 10 is provided at one end of the shaft head 9.

Figure 2 and Figure 3 As shown, it serves as a limit switch, ensuring that when the connecting shaft 6 rotates, it drives the rotating body 3 to rotate without any rotational offset or slippage, thus improving the stability of rotation. At this time, the bolt hole 18 and the threaded connection hole 16 are aligned, and one end of the fixing bolt 19 passes through the bolt hole 18 and is threadedly connected to the threaded connection hole 16, thereby fixing the rotating body 3 to the mounting component 22. The detachable mounting component 22 is easy to replace.
