Therefore, the problems that the roller body shakes in the grinding process due to a gap existing when the roller shaft and the roller body are fixed through a bolt or a pin shaft, and the rotating stability of the ironing roller cannot be guaranteed due to the fact that only two tips are used for positioning the whole ironing roller are solved, and the grinding precision of the roller body is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil production equipment, in particular to an ironing roller grinding and positioning device. Background Art

[0002] In the production process of aluminum foil strips, due to factors such as high running speed when the strips are coiled and fluctuations in coiling tension control, there will be slight slippage between the layers of the strips, causing surface damage to the strips, affecting product quality, or causing problems such as coiling misalignment. In order to solve these problems, when the strips are coiled, it is necessary to install an ironing roller device on the exit side of the aluminum foil rolling mill to allow the ironing roller to press the strips tightly to reduce slippage and strip misalignment and ensure good coiling.

[0003] After long-term use, the cylindricity of the ironing roller will not meet the use requirements, so the roller body of the ironing roller needs to be ground. The existing ironing roller grinding is to place the ironing roller on a grinding machine for grinding. The operation is: let the top of the grinder support the roller shaft to achieve the stability of the roller shaft, and the roller shaft and the roller body are fixedly connected (such as the utility model patent with the authorization publication number CN218052072U), and then the power output end of the grinder is fixedly connected to the roller shaft, thereby driving the ironing roller to rotate on the grinder. At this time, the roller body of the ironing roller can be ground.

[0004] The roller shaft and roller body are fixedly connected with bolts or pins, and there is a gap. The roller body shakes during the grinding process, and only two centers are used to position the roller shaft. There will be slight vibration during the roller body grinding process, which reduces the grinding accuracy of the roller body. Summary of the invention

[0005] In order to solve the problem that the roller body of the existing ironing roller will shake and vibrate during grinding, thereby reducing the grinding accuracy of the roller body, the utility model proposes an ironing roller grinding positioning device, which makes the connecting rod on the outer side of the pressure cover abut against the claws on the grinder dial, so that the power mechanism of the grinder drives the dial claws to rotate and then drives the roller body to rotate, and the roller shaft is limited by the top of the grinder so that it does not rotate synchronously with the roller body, thereby avoiding the gap between the roller shaft and the roller body when they are fixed by bolts or pins, causing the roller body to shake during the grinding process, and the problem that only two tops can position the entire ironing roller and cannot ensure the stability of the ironing roller positioning, thereby improving the grinding accuracy of the roller body.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A grinding and positioning device for an ironing roller comprises a roller shaft and a roller body, wherein the roller shaft is located at the center of the roller body, the roller shaft is inserted into the roller body, and pressure caps are provided at both ends of the roller body, a connecting rod is fixed on one of the pressure caps, the connecting rod is located on the side of the pressure cap away from the roller body, one side of the connecting rod abuts against the side of the claw of the grinder dial, and a center hole is provided at both ends of the roller shaft, and the center hole matches the center on the grinder. The output end of the motor on the grinder is fixedly connected to the dial, thereby driving the dial to rotate along its center point, and a gap is provided between the center and the dial, and the center is installed on the grinder, and the center has no power source and will not rotate actively, and mainly plays a role in limiting the roller shaft.

[0008] Furthermore, the pressure cover on one side of the roller body includes a first positioning ring, a connecting plate and a second positioning ring, the first positioning ring and the second positioning ring are respectively fixed on both sides of the connecting plate, the first positioning ring is inserted into the inner side of the roller body, the connecting plate is fixedly connected to the roller body, the connecting plate and the second positioning ring are located on the outer side of the roller shaft, and a gap is provided between the inner side surface of the connecting plate and the second positioning ring and the outer side surface of the roller shaft. A gap is provided between the connecting plate and the second positioning ring and the outer side surface of the roller shaft to reduce the influence of the roller shaft's own precision on the roller body wear.

[0009] Furthermore, the gland on the other side of the roller body includes a first positioning ring and a connecting plate, wherein the first positioning ring is inserted into the inner side of the roller body, and a gap is provided between the inner side of the connecting plate and the outer side of the roller shaft. While reducing the influence of the roller shaft's own precision on the roller body wear, the center of the roller body, the center of the roller shaft and the top of the grinder are in a highly coincident state.

[0010] Furthermore, the connecting plate is a flange, and the connecting plate is connected and fixed to the roller body by a first bolt. The gland and the roller body are fixed together by the flange.

[0011] Furthermore, a bearing is provided in the roller body, the bearing sleeve is arranged outside the roller shaft, and the outer wall of the bearing is in contact with the inner wall of the roller body. The bearing avoids direct contact between the roller shaft and the roller body.

[0012] Furthermore, a skeleton oil seal is provided inside the roller body, the skeleton oil seal sleeve is arranged outside the roller shaft, the outer wall of the skeleton oil seal is in contact with the inner wall of the roller body, and the skeleton oil seal is located on the side of the bearing away from the gland, so as to ensure the sealing inside the roller body.

[0013] Furthermore, the top hole is conical.

[0014] Furthermore, two connecting rods are fixed on the gland, the two connecting rods are symmetrical about the axis center of the roller shaft, and one side of the connecting rod abuts against the side of the claw of the grinder dial. The two claws on the dial are symmetrically arranged, and the two connecting rods on the gland are symmetrical about the axis center of the roller shaft, and the two connecting rods abut against the opposite side of the two claws, respectively, to ensure that the claws can stably drive the connecting rods to rotate.

[0015] Furthermore, the connecting rod is fixedly connected to the connecting plate.

[0016] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model fixes the connecting rod on the side of the pressure cover away from the roller body, and then the connecting rod is pressed against the claw on the grinder dial, and the top holes at both ends of the roller shaft cooperate with the top on the grinder to limit the roller shaft. When the motor on the grinder drives the dial claw to rotate, the roller body is driven to rotate through the connecting rod. At this time, the roller shaft will not rotate synchronously with the roller body, thereby avoiding external influences on the roller body during grinding, and improving the grinding accuracy of the roller body.
