[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0028] A rolling test bench for rubber rollers, see Figures 1 to 4 , comprising a base 1, a driving mechanism 2 is arranged inside the base 1, a guide rod 3 is inserted inside the side of the base 1, a limit frame 4 is fixedly connected to the top of the guide rod 3, a group of auxiliary components 5 are symmetrically arranged on the top of the limit frame 4, a limit mechanism 6 is arranged inside the limit frame 4, and a rubber roller body 7 is clamped at the bottom of the limit mechanism 6;

[0029] The limiting mechanism 6 includes a small motor 601, and the movable end of the small motor 601 is connected to a forward and reverse screw rod 602. A group of threaded frames 603 are movably sleeved on the surface of the forward and reverse screw rod 602, and a limiting rod 604 is fixedly connected to the rear of the threaded frame 603. Among them, the small motor 601 forms a threaded transmission structure with the threaded frame 603 through the forward and reverse screw rod 602, and the threaded frame 603 and the limiting rod 604 are fixedly connected. The outer side of the end of the limiting rod 604 away from the threaded frame 603 is fitted with a limiting groove 605. A group of clamping rods 606 are symmetrically arranged at the bottom of a group of threaded frames 603. Furthermore, the clamping rod 606 is L-shaped, and the clamping rod 606 and the threaded frame 603 are fixedly connected. A limiting ring plate 607 is fixedly sleeved on the surface of the clamping rod 606. The utility model effectively drives the forward and reverse screw rods 602 to rotate through a small motor 601, and a group of threaded frames 603 on the surfaces of the forward and reverse screw rods 602 move horizontally due to the influence of the limiting rod 604, so that the group of threaded frames 603 are separated from or approached by each other, which makes it easier for a group of clamping rods 606 and limiting ring plates 607 to adapt to and clamp rubber roller bodies 7 of different sizes, thereby improving adaptability.

[0030] It is worth noting that the driving mechanism 2 includes a driving roller 201, and shafts 202 are fixedly connected on both sides of the driving roller 201. The end of the shaft 202 away from the driving roller 201 is connected to a flange seat 203, a left rotating frame 204 is attached to the surface of the left flange seat 203, and a right rotating frame 205 is attached to the surface of the right flange seat 203. The end of the right rotating frame 205 away from the flange seat 203 is connected to a driving motor 206, and a number of bolts 207 are evenly penetrated inside the flange seat 203, wherein the flange seat 203 forms a detachable structure with the left rotating frame 204 and the right rotating frame 205 through the bolts 207. In the utility model, the right rotating frame 205 is effectively driven to rotate by the driving motor 206, thereby driving the flange seat 203, the shaft rod 202, the driving roller 201, and the left rotating frame 204 connected to the right rotating frame 205 to rotate, so that the driving roller 201 can drive the rubber roller body 7 to rotate by means of friction, and the driving roller 201 can be disassembled, inspected and replaced by removing the bolts 207.

[0031] It is worth noting that the auxiliary component 5 includes a vertical rod 501, and a plurality of weights 502 are sleeved on the outside of the vertical rod 501, wherein the vertical rod 501 is fixedly connected to the limit frame 4, and the weights 502 are movably engaged with the vertical rod 501. The utility model adjusts the pressure on the rubber roller body 7 by adding or reducing the weights 502 outside the vertical rod 501, so as to simulate different load conditions during use.

[0032] Working principle: firstly, empty the weight 502 on the device, and weigh the guide rod 3, the limit frame 4, the vertical rod 501, and the limit mechanism 6 as a whole, which is the initial load-bearing capacity of the rubber roller body 7. After weighing, insert the guide rod 3 into the base 1 to complete the assembly, and then drive the positive and negative screw rods 602 to rotate through the small motor 601. Under the influence of the limit rod 604, a group of threaded frames 603 on the surface of the positive and negative screw rods 602 move horizontally, so that a group of threaded frames 603 are moved away from or close to each other, so that a group of clamping rods 606 and the limit ring plate 607 are adapted to clamp the rubber roller body 7. The positioned rubber roller body 7 is in contact with the driving roller 201 under the influence of gravity. The pressure on the rubber roller body 7 is adjusted by adding a weight 502 outside the vertical rod 501, so as to simulate different load conditions during use. Then, the right rotating frame 205 is driven to rotate by the driving motor 206, thereby driving the flange seat 203, the shaft 202, the driving roller 201 and the left rotating frame 204 connected to the right rotating frame 205 to rotate, so that the driving roller 201 can drive the rubber roller body 7 to rotate with the help of friction. After testing for a period of time, the rubber roller body 7 is removed to observe its wear degree, and the rolling detection of the rubber roller body 7 is completed.
