Description

Technical Field

[0001] This utility model relates to the field of pinch roller technology, specifically a combined wear-resistant pinch roller. Background Technology

[0002] There are two types of pinch rolls: centralized drive and individual drive. Centralized drive is a DC motor that drives the upper and lower pinch rolls together through a combined reducer. The speed ratio of the transmission shaft gearbox is usually slightly smaller than the ratio of the upper and lower roll diameters to adapt to the downward bending trend of the strip. In order to ensure that the linear speed of the upper and lower rolls is the same, they must always be regrinded according to a certain diameter ratio.

[0003] In response, Chinese Patent Application Publication No. CN218453819U discloses a high-chromium wear-resistant alloy pinch roll, belonging to the field of pinch roll technology. A high-chromium wear-resistant alloy pinch roll includes a pinch roll body, with transmission sleeves at both ends of the pinch roll body. The transmission sleeves are connected to the pinch roll body by screws. An air valve is installed inside the transmission sleeve, and the air valve is rotatably connected to the transmission sleeve via a bearing. To address the problem that traditional adjustment mechanisms require adjusting the pinch roll according to the thickness of the object being pinched, which is inconvenient due to the need for coordinated speed control, the pinch roll design addresses this issue. When pressurized gas is introduced through the air valve, the expanding blades on the roll surface are pushed out, reducing the gap between the pinch roll bodies and expelling the gas. The expanding blades then retract inward, widening the gap between the roll bodies.

[0004] However, in actual use, the pinch rollers cannot be installed in combination. When the outer surface of the pinch roller is damaged, the whole thing needs to be replaced. The damaged parts of the pinch roller cannot be replaced individually. At the same time, the combined pinch rollers need to be limited as a whole during installation. Therefore, improving and perfecting the above problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a combined wear-resistant pinch roll to solve the problems mentioned in the background art, such as the inability to install the pinch roll in combination during use, the need to replace the entire pinch roll when the outer surface of the pinch roll is damaged, the inability to replace the damaged parts of the pinch roll individually, and the need for overall positioning during the installation of the combined pinch roll.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined wear-resistant pinch roller, comprising a first connecting shaft, a convex ring provided on the outer surface of the first connecting shaft, a first wear-resistant sleeve installed on the surface of the first connecting shaft, a semi-circular groove provided on the inner sidewall of the first wear-resistant sleeve, the semi-circular groove and the convex ring being mutually adapted to each other, and a stabilizing groove provided on the front surface of the first connecting shaft.

[0007] A stabilizing column is installed inside a stabilizing groove. A fitting ring is installed on the front surface of the stabilizing column, a fitting ring is installed on the outer surface of the fitting ring, a top block is installed on the upper surface of the fitting ring, and a stabilizing block is provided on the lower surface of the top block.

[0008] Preferably, a connecting ring is installed on the front surface of the fitting ring, and the stabilizing column and the stabilizing groove are mutually adapted.

[0009] Preferably, a fixing sleeve is installed inside the back of the first connecting shaft, and a fixing post is installed on the back of the fixing sleeve.

[0010] Preferably, the outer surface of the fixing sleeve is equipped with inserts, and three sets of inserts are provided.

[0011] Preferably, a second connecting shaft is installed on the outer surface of the fixing column, and a fixing groove is formed on the front surface of the second connecting shaft, and the fixing groove is adapted to the fixing column.

[0012] Preferably, the outer surface of the second connecting shaft is provided with a slot, the slot and the plug are adapted to each other, and a second wear-resistant sleeve is installed on the surface of the second connecting shaft.

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

[0014] 1. This combined wear-resistant pinch roller, through the setting of a first connecting shaft, a convex ring, a first wear-resistant sleeve, a semi-circular groove, a stabilizing groove, a stabilizing column, a bonding ring, a bonding ring, a top block, a stabilizing block, and a connecting ring, is installed by first installing the stabilizing column into the inside of the stabilizing groove. Then, the back of the bonding ring will adhere to the front surface of the first connecting shaft and the first wear-resistant sleeve, resulting in a good overall limiting effect. At the same time, the first wear-resistant sleeve is slidably installed onto the outer surface of the convex ring and the first connecting shaft through the semi-circular groove, resulting in a good overall installation effect. Subsequently, the lower surfaces of the top block and the stabilizing block will abut against the outer surface of the first wear-resistant sleeve. The stabilizing block can clamp and stabilize the outer surface of the first wear-resistant sleeve as a whole, resulting in a good overall clamping effect. Moreover, the stabilizing block can be connected to the drive device. The first wear-resistant sleeve after the overall combination installation has good stability, demonstrating the practicality of the design.

[0015] 2. This combined wear-resistant pinch roller, through the setting of a first connecting shaft, a fixed sleeve, a fixed column, an insert column, a second connecting shaft, a fixed groove, a slot, and a second wear-resistant sleeve, when the first connecting shaft and the second connecting shaft are combined, firstly, the fixed sleeve and the fixed column are inserted into the fixed groove as a whole, so the connection between the first connecting shaft and the second connecting shaft is relatively stable. Then, the insert column is also inserted into the slot. Then, the outer surface of the second connecting shaft can also be fitted with the second wear-resistant sleeve. Moreover, the back of the first connecting shaft and the second connecting shaft after installation also have the same fitting ring and connecting ring design. Therefore, the overall combined installation can avoid the need to replace the whole thing after subsequent damage, which reflects the practicality of the design. Attached Figure Description
