Description

Technical Field

[0001] This application relates to the field of I-beam roller technology, and more specifically, to an I-beam roller for a semi-steel curtain trolley. Background Technology

[0002] In the semi-steel tire production line, the semi-steel cord fabric trolley is the core tooling equipment for transferring and winding strip materials such as cord fabric and padding fabric. The rationality of its I-beam structure directly affects production efficiency and tooling versatility. After the tractor accurately transports the semi-steel cord fabric trolley to the designated machine position, it releases the brake disc on the trolley and drives the material roll I-beam to rotate at high speed through the power mechanism, thereby completing the winding operation of the cord fabric or padding fabric. After the winding is completed, the brake disc brakes again.

[0003] In related technologies, in order to facilitate the transportation of I-beam reels, for example, the prior art patent with publication number CN205328378U provides an I-beam reel. The I-beam reel uses the cooperation of the end flange of the drum body, the first notch groove, the through hole in the middle of the baffle and the second notch groove to make the baffle separate from the drum body, thereby reducing transportation costs.

[0004] While the existing technical solutions described above separate the I-beams into a roll body and baffles to facilitate their transport, the side flanges on both sides of the I-beams cannot be adjusted in position. This means that a single I-beam can only be matched with a fixed width of padding roll. In actual production scenarios, different specifications of tire products correspond to different widths of padding materials. To meet production needs, companies need to equip themselves with various specifications of semi-steel cord fabric trolleys to accommodate different widths of I-beams, increasing equipment procurement costs and warehousing space requirements. Furthermore, dedicated tooling trolleys cannot be used across workstations. When a trolley at one workstation malfunctions, trolleys at other workstations cannot be used as substitutes due to incompatible specifications, further reducing production flexibility and fault tolerance.

[0005] In view of this, we propose a semi-steel curtain fabric trolley with an I-beam wheel. Utility Model Content

[0006] The purpose of this application is to provide a semi-steel curtain trolley with an I-beam wheel, which can effectively solve the problem in the prior art that the I-beam wheel side rails cannot be adjusted and can only be adapted to a single width of padding roll. It achieves the effect of horizontally adjusting the side rails through a split structure design, which can be adapted to padding rolls of various widths.

[0007] This application provides a semi-steel cord fabric trolley I-beam wheel, comprising: The core is rotatably mounted on the top of the trolley body; There are two side retaining rings, and the two side retaining rings are located on both sides of the winding core; The side retaining ring has a threaded hole on its circumference, an internal hexagon bolt is threaded on the inner side of the threaded hole, a nut is threaded on the outer side of the internal hexagon bolt, and the end of the internal hexagon bolt abuts against the outer side of the core.

[0008] As an optional solution to the technical solution of this application, a pressure plate is provided on the outer side of the core, and end caps are provided on both sides of the core. The core, pressure plate and end caps are fixed together by a number of screws.

[0009] As an optional solution to the technical solution of this application, a mandrel is fixedly provided on the inner side of the core, and the mandrel is driven to rotate by an external force.

[0010] As an optional solution to the technical solution of this application, a power disk is fixedly provided on both sides of the mandrel, and the power disk is driven to rotate by an external driving device.

[0011] As an optional solution to the technical solution in this application, a brake band is provided on the outer side of the power disc on one side.

[0012] As an optional solution to the technical solution of this application, a bearing is provided between the end cover and the power plate, the outer side of the spindle is fixedly disposed with the inner ring of the bearing, and the bottom of the bearing is fixedly disposed with the outer side of the trolley body through a base plate.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: (1) This application adopts the separate manufacturing of the core and two side retaining rings. The side retaining rings are provided with threaded holes around the perimeter. The threaded holes are provided with internal hex bolts to hold the core and are tightened in the opposite direction with nuts to fix it. The size of the middle hole of the side retaining ring is basically the same as that of the core. The side retaining rings can be adjusted horizontally by internal hex bolts. Therefore, it effectively solves the problem in the prior art that the side retaining rings cannot be adjusted and can only be adapted to a single width of padding roll. It realizes the effect of horizontal adjustment of the side retaining rings through the split structure design, which can be adapted to a variety of widths of padding rolls. It realizes the effect of the semi-steel curtain trolley and the semi-steel inner lining trolley being interchangeable at the workstation. Thus, it realizes the effect of one tooling trolley being interchangeable at multiple workstations, effectively solving the problem of too many types of tooling trolleys on site.

[0014] (2) By setting a bearing at the contact part between the side retaining ring and the trolley body and fixing the bearing to the base plate, the base plate is fixed to the trolley body, which can greatly reduce the frictional resistance between the H-beam and the trolley when the H-beam rotates, avoid the wear of parts caused by friction, and improve the rotational stability and smooth operation of the H-beam.

Detailed Implementation

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 and Figure 4 This application discloses a semi-steel cord fabric trolley I-beam wheel, including a core 1, which is rotatably mounted on the top of the trolley body 100. Side retaining rings 2 are provided on both sides of the core 1. The side retaining rings 2 have threaded holes 21 on their periphery. The inner thread of the threaded hole 21 is provided with an internal hexagon bolt 22, and the outer thread of the internal hexagon bolt 22 is provided with a nut 23. The end of the internal hexagon bolt 22 abuts against the outer side of the core 1.

[0018] By loosening the nut 23 and then rotating the socket head cap screw 22, the socket head cap screw 22 is moved horizontally along the threaded hole 21, moving away from the outer side of the core 1. This allows the side retaining ring 2 to move along the axial direction of the core 1. After the distance between the two side retaining rings 2 is adapted to the current width of the padding roll, the socket head cap screw 22 is rotated so that the end of the socket head cap screw 22 abuts against the core 1. Then, the nut 23 is tightened in the opposite direction to fix the side retaining ring 2 and the core 1 relative to each other, thus completing the width adjustment to adapt to the target padding roll.

[0019] Reference Figure 1 and Figure 3 A pressure plate 11 is provided on the outer side of the core 1, and end caps 12 are provided on both sides of the core 1. The core 1, pressure plate 11 and end caps 12 are fixed by a number of screws 111.

[0020] First, the pressure plate 11 is attached to the outer wall of the core 1 to ensure a tight fit between the pressure plate 11 and the core 1, thereby enhancing the structural strength of the core 1. Then, the end caps 12 are respectively attached to both ends of the core 1, aligning the edges of the end caps 12 with the ends of the core 1 to prevent the edge of the padding cloth from rubbing against other components. Finally, the screws 111 are screwed into the corresponding mounting holes on the end caps 12, the core 1, and the pressure plate 11 in sequence, so that the three form a stable overall structure, preventing the core 1 from becoming loose or deformed during high-speed rotation.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A spindle 3 is fixedly installed on the inner side of the core 1. The spindle 3 is driven to rotate by an external force. A power disk 4 is fixedly installed on both sides of the spindle 3. The power disk 4 is driven to rotate by an external drive device. A brake band 5 is installed on the outer side of one side of the power disk 4. A bearing 6 is installed between the end cover 12 and the power disk 4. The outer side of the spindle 3 is fixedly installed with the inner ring of the bearing 6. The bottom of the bearing 6 is fixedly installed on the outer side of the trolley body 100 through the base plate 61.

[0022] By first fixing the inner ring of the bearing 6 to the outer wall of the spindle 3, then fixing the bottom of the outer ring of the bearing 6 to the base plate 61, and then installing the base plate 61 on the top of the trolley body 100, the spindle 3 and the trolley body 100 can be rotated and supported. When the external drive device drives the power disk 4 to rotate, the power disk 4 drives the spindle 3 to rotate synchronously, and the spindle 3 in turn drives the core 1 to rotate to complete the padding cloth winding operation. After winding is completed, the brake band 5 is controlled to adhere to the outer wall of the power disc 4 on one side. Through the friction between the brake band 5 and the power disc 4, the power disc 4, the spindle 3 and the core 1 are quickly stopped from rotating. At the same time, the bearing 6 can reduce the frictional resistance when the core 1 rotates, ensuring that the entire rotation process is smooth and without jamming.

[0023] In summary, when using the semi-steel curtain trolley I-beam wheel disclosed in this application embodiment, first adjust the distance between the two side retaining rings 2 according to the width of the padding cloth to be rolled: loosen the nut 23, then rotate the hexagonal bolt 22 to move the hexagonal bolt 22 horizontally along the threaded hole 21, so that the hexagonal bolt 22 moves away from the outer side of the core 1, thereby allowing the side retaining rings 2 to move along the axial direction of the core 1. After the distance between the two side retaining rings 2 is adapted to the current width of the padding cloth roll, rotate the hexagonal bolt 22 to make the end of the hexagonal bolt 22 press against the core 1, then tighten the nut 23 in the opposite direction to fix the side retaining rings 2 and the core 1 relative to each other, thus completing the width adjustment to adapt to the target padding cloth roll; Then, the bearing 6 is fixed to the trolley body 100 through the base plate 61 to realize the rotation support of the spindle 3. When the tractor transports the trolley body 100 to the designated machine position, the external drive equipment drives the power plate 4 to rotate, and drives the core 1 to rotate through the spindle 3 to wind up the padding cloth. After the winding is completed, the brake band 5 is used to brake the power plate 4 to stop the core 1. Throughout the process, the I-beam wheel not only flexibly adapts to various widths of padding rolls, but also achieves the effect of horizontal adjustment of the side guards through the split structure design, adapting to various widths of padding rolls. This enables the semi-steel curtain trolley and the semi-steel lining trolley to be used interchangeably at multiple workstations, thus achieving the effect of one tooling trolley being usable at multiple workstations and effectively solving the problem of too many types of tooling trolleys on site.
