[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1 and Figure 2 This utility model discloses a device for reducing the size of the roller shaft head, which includes a base 100. A fixing component 200 is provided at the upper end of the base 100. The fixing component 200 includes a fixing block 201 rotatably connected to the upper end of the base 100.

An abutment ring 207 is fixedly connected to the end of the second connecting plate 206 away from the fixing block 201. A support frame 300 is fixedly connected to the lower end of the base 100. A first motor 400 is fixedly connected to the upper end of the support frame 300. A rotating shaft 500 is fixedly connected to the output end of the first motor 400. The upper end of the rotating shaft 500 is fixedly connected to the lower end of the fixing block 201.

[0023] Specifically, the idler roller shaft to be processed is placed horizontally inside the positioning ring 205. The operator must simultaneously hold the handles of the first connecting plate 204 and the second connecting plate 206 and pull it smoothly out of the guide groove of the fixed plate 203. At this time, the first connecting plate 204 moves upward along the guide rail structure of the sliding groove 202, causing the positioning ring 205 to rise synchronously; at the same time, the second connecting plate 206 moves downward along the guide rail structure of the sliding groove 202, driving the abutment ring 207 to slide downward along the vertical guide rod. When the arc-shaped contact surface of the abutment ring 207 is completely in contact with the upper surface of the idler roller shaft, the first connecting plate 204 and the second connecting plate 206 are reinserted into the fixed plate 203, thereby firmly clamping the idler roller shafts of different diameters. After the shaft head reduction processing is completed, the first motor 400 is started, which drives the rotating shaft 500 to rotate, and the fixed block 201 rotates accordingly, causing the idler roller shaft to rotate 180° around its axis. Operators can follow the same procedure to reduce the diameter of the other end of the shaft to ensure that the machining dimensions of both ends are consistent.

[0024] Reference Figure 1 , Figure 3 and Figure 4 A limiting component 600 is provided at the upper end of the base 100. The limiting component 600 includes two limiting grooves 601 formed at the upper end of the base 100. One limiting groove 601 includes a reciprocating screw 602 rotatably connected inside the limiting groove 601. A limiting plate 603 is threadedly connected to the outer side of the reciprocating screw 602. A mounting bracket 604 is fixedly connected to the top of the limiting plate 603. A mounting groove 605 is formed at the upper end of the base 100. A second motor 606 is fixedly connected inside the mounting groove 605. The output end of the second motor 606 is fixedly connected to the reciprocating screw 602. A traction tube 607 is fixedly connected inside the other limiting groove 601. A traction block 608 is slidably connected to the outer side of the traction tube 607. The upper end of the traction block 608 is fixedly connected to the mounting bracket 604. The lower end of the mounting bracket 604 is fixedly connected to the multi-stage electric telescopic column 609. The lower end of the multi-stage electric telescopic column 609 is fixedly connected to the abutment ring 610. The upper end of the base 100 is provided with a pushing assembly 700. The pushing assembly 700 includes a fixing frame 701 fixedly connected to the upper end of the base 100. The upper end of the fixing frame 701 is fixedly connected to a threaded ring 702. The threaded ring 702 is internally threaded with a threaded rod 703. The end of the threaded rod 703 away from the abutment ring 610 is fixedly connected to a turntable 704. The end of the threaded rod 703 away from the turntable 704 is fixedly connected to a pushing plate 705. The upper end of the base 100 is provided with a scale 800.

[0025] Specifically, after the idler roller shaft is fixed, the electric telescopic column 609 is activated to drive the abutment ring 610 downwards, aligning its center with the idler roller shaft head. Then, the second motor 606 is activated to drive the reciprocating screw 602 to rotate, causing the limit plate 603 to move, allowing the mounting bracket 604 to push the abutment ring 610 closer to the shaft head via the electric telescopic column 609. The distance between the abutment ring 610 and the shaft head is measured and adjusted to the required distance using the scale 800. Next, the turntable 704 is rotated to rotate the threaded rod 703, causing the push plate 705 to move and push the shaft head into place. Finally, a necking mechanism is used inside the idler roller shaft to complete the compression and necking operation.

[0026] Working principle: The idler roller shaft to be processed is placed horizontally inside the positioning ring 205. The operator must simultaneously hold the handles of the first connecting plate 204 and the second connecting plate 206 and pull it out smoothly from the guide groove of the fixed plate 203. At this time, the first connecting plate 204 moves upward along the guide rail structure of the sliding groove 202, driving the positioning ring 205 to rise synchronously; at the same time, the second connecting plate 206 moves downward along the guide rail structure of the sliding groove 202, driving the abutment ring 207 to slide downward along the vertical guide rod. When the arc-shaped contact surface of the abutment ring 207 is completely in contact with the upper surface of the idler roller shaft, the first connecting plate 204 and the second connecting plate 206 are reinserted into the fixed plate 203, thereby firmly clamping the idler roller shafts of different diameters. Then, the electric telescopic column 609 is activated to drive the abutment ring 610 to slide down, aligning its center with the head of the idler roller shaft. Then, the second motor 606 is started to drive the reciprocating screw 602 to rotate, which in turn moves the limit plate 603, causing the mounting bracket 604 to push the abutment ring 610 closer to the shaft head via the electric telescopic column 609. The distance between the abutment ring 610 and the shaft head is measured and adjusted to the required distance using the scale 800. Next, the turntable 704 is rotated to rotate the threaded rod 703, which moves the push plate 705 and pushes the shaft head into place. Finally, the necking mechanism is used inside the idler roller shaft to complete the compression and necking operation. The first motor 400 is started, which drives the rotating shaft 500 to rotate, and the fixed block 201 rotates accordingly, causing the idler roller shaft to rotate 180° around its axis. The operator can follow the same process to perform diameter reduction machining on the other end of the shaft head to ensure that the machining dimensions at both ends are consistent.
