[0023] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.

[0024] Example 1, such as Figure 1 , 2 As shown in Figures 3 and 4, an unwinding device for a rubber raw material roll includes a support 10, a first fixing member 20, a second fixing member 30, and a transmission structure 40. The first fixing member 20 is rotatably mounted on the support 10 and is used to fix the rubber raw material roll. The second fixing member 30 is rotatably mounted on the support 10 and is located on the side of the first fixing member 20. The second fixing member 30 is used to receive the protective film of the rubber raw material roll, and the protective film of the rubber raw material roll can be wound around the second fixing member 30. The transmission structure 40 is installed between the first fixing member 20 and the second fixing member 30 so that the first fixing member 20 and the second fixing member 30 move synchronously.

[0025] The bracket 10 includes a base frame 11 and a first connecting frame 12 that are connected to each other. A first fixing member 20 is disposed on the base frame 11, and a second fixing member 30 is disposed on the first connecting frame 12. The base frame 11 is supported on the ground, thereby effectively supporting the first fixing member 20. The first connecting frame 12 can fix the second fixing member 30, thereby making the position of the second fixing member 30 more stable.

[0026] The first fixing member 20 includes a first disc 21, and the second fixing member 30 includes a second disc 31. The axis of the first disc 21 and the axis of the second disc 31 are arranged parallel to each other. The structure of the first disc 21 and the second disc 31 is simple and easy to set up, and can effectively fix the rubber raw material roll and the protective film.

[0027] The area of ​​the first disc 21 is larger than the area of ​​the second disc 31, which can fix a larger rubber raw material roll and avoid the second disc 31 occupying a large space.

[0028] The first disc body 21 includes a first baffle 211 and a second baffle 212 installed at intervals, and a first connecting shaft 213 connected between the first baffle 211 and the second baffle 212. The first baffle 211 and the first connecting shaft 213 are detachably installed. The first baffle 211 and the second baffle 212 can effectively stop the rubber raw material roll, thereby making the position of the rubber raw material roll more stable.

[0029] The second disc 31 includes a third baffle 311 and a fourth baffle 312 spaced apart, and a second connecting shaft 313 connected between the third baffle 311 and the fourth baffle 312. The third baffle 311 and the second connecting shaft 313 are detachably installed. The third baffle 311 and the fourth baffle 312 can position the protective film so that it can be wound around the second connecting shaft 313.

[0030] In the direction from near the second connecting shaft 313 to away from the second connecting shaft 313, the distance between the third baffle 311 and the fourth baffle 312 gradually increases, which can show a larger amount of protective film wrapped around it.

[0031] The transmission structure 40 includes a first gear 41, a second gear 42, and a chain 43 connected to the first gear 41 and the second gear 42. The first gear 41 is connected to the first connecting shaft 213, and the second gear 42 is connected to the second connecting shaft 313. The motor drives the first gear 41 to rotate, thereby driving the second gear 42 to rotate. The structure of the first gear 41, the second gear 42, and the chain 43 is simple and can effectively achieve linkage.

[0032] The diameter of the first gear 41 is larger than the diameter of the second gear 42, which ensures that the protective film can be peeled off from the rubber raw material roll.

[0033] It should be noted that the chain 43 can be a chain or belt drive; the first gear 41 and the second gear 42 can be guide wheels.

[0034] Example 2, as Figure 1 , 2 As shown in Figures 3, 4, and 5, similar to Embodiment 1, an unwinding device for a rubber raw material roll includes a second connecting frame 13 in the support 10. The second connecting frame 13 is connected to the base frame 11 and spaced apart from the first connecting frame 12. A correction structure 50 is installed on the second connecting frame 13. The correction structure 50 includes a first roller 51 and a second roller 52, with a gap between them. The axes of the first roller 51, the second roller 52, and the first fixing member 20 are arranged parallel to each other. The rubber strip of the rubber raw material roll passes through the gap between the first roller 51 and the second roller 52. The second connecting frame 13 can fix the correction structure 50. The correction structure 50 can guide and position the torn rubber strip on the rubber raw material roll, thereby preventing it from twisting and deforming, thus improving production efficiency.

[0035] The second connecting frame 13 is provided with a strip hole and a connecting hole. The second roller 52 is fixed in the connecting hole, and the first roller 51 is movably disposed in the strip hole. The correction structure 50 also includes an elastic element, which is connected between the first roller 51 and the second roller 52 so that the first roller 51 and the second roller 52 can be brought closer to each other, thereby enabling the extrusion of rubber raw materials.

[0036] The first connecting frame 12 and the second connecting frame 13 can rotate relative to the base frame 11, so that the positions of the first connecting frame 12 and the second connecting frame 13 can be adjusted, thereby allowing the straightening structure 50 and the second fixing member 30 to be adjusted to a suitable position.

[0037] This utility model discloses an unwinding device for rubber raw material rolls. A first fixing member is rotatably mounted on a support, and the rubber raw material roll is fixed to the first fixing member. A second fixing member is rotatably mounted on the support and located to the side of the first fixing member, and a protective film of the rubber raw material roll can be wound around the second fixing member. A transmission structure is disposed between the first and second fixing members, enabling the first and second fixing members to move together. The rubber raw material roll is fixed to the first fixing member and can rotate with the first fixing member, thereby achieving unwinding. When the second fixing member rotates, it can wind the protective film, thereby collecting the protective film together. The transmission structure enables the first and second fixing members to move together, thereby avoiding the situation where the protective film cannot be separated from the rubber raw material roll. This effectively solves the problem in related technologies where the protective film on the rubber raw material roll needs to be manually processed, resulting in high production costs.
