Description

A type of expansion roller mounting structure Technical Field

[0001] This utility model relates to the field of fiberglass cloth production technology, and in particular to an expansion roller mounting structure. Background Technology

[0002] With social development, the demand for high-performance fiberglass cloth is increasing. Some products require thinner fiberglass cloth, but existing production equipment is prone to folding when winding thinner fiberglass cloth. Therefore, it is necessary to install a widening roller on the existing equipment to widen the fiberglass cloth before winding. Since the widening roller is not required when producing other fiberglass cloth products, the installation structure of the widening roller needs to be easy to disassemble and adjust. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned problems in the existing technology and provide an expansion roller mounting structure.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] An expanding roller mounting structure includes two symmetrically arranged fixed support plates. Each fixed support plate is bolted with a first seated bearing and a second seated bearing. A winding pressure roller is installed between the two sets of first seated bearings, and a guide roller is installed between the two sets of second seated bearings. The structure also includes two sets of height-adjustable movable supports and an expanding roller. The expanding roller is mounted on the inner side of the fixed support plates by bolts that mount the first and second seated bearings. The shafts at both ends of the expanding roller are respectively mounted in the two sets of movable supports.

[0006] Each set of movable supports includes an upper support block, a lower support block, a mounting block, four support screws, a third bearing housing, and a third ball bearing. The upper support block is mounted on the inner side of the fixed support plate by bolts for mounting a first bearing housing, and the lower support block is mounted on the inner side of the fixed support plate by bolts for mounting a second bearing housing. Two support screws perpendicular to the lower support block are screwed onto the lower support block, and two support screws perpendicular to the upper support block are screwed onto the upper support block. The mounting block is sandwiched between the support screws screwed onto the lower support block and the support screws screwed onto the upper support block. The third bearing housing is mounted on the inner side of the mounting block, and the third ball bearing is sandwiched between the third bearing housing and the mounting block. The shaft of the expansion roller is interference-fitted into the inner ring of the third ball bearing.

[0007] The mounting block has two spherical limiting grooves at its top and bottom, and the end of the support screw that contacts the mounting block is a hemispherical pressing block that is inserted into the limiting groove.

[0008] The end of the support screw furthest from the mounting block is provided with an internal hexagonal hole.

[0009] The mounting block has a circular clearance groove at its center, and the inner diameter of the clearance groove is larger than the outer diameter of the inner ring of the third ball bearing.

[0010] The beneficial effects of this utility model are as follows: the movable bracket is installed inside the fixed bracket plate by bolts for installing the first and second seated bearings, and the shafts at both ends of the expansion roller are installed in the two sets of movable brackets respectively. There is no need to cut, weld, or drill to modify the original equipment, which facilitates the installation and disassembly of the expansion roller; the mounting block is clamped by the support screw in cooperation with the upper and lower support blocks, which facilitates the adjustment of the position of the expansion roller.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] As shown in Figures 1 to 5, a widening roller mounting structure includes two symmetrically arranged fixed support plates 1. Each fixed support plate 1 is equipped with a set of first seated bearings 2 and a set of second seated bearings 3 by bolts 6. A winding pressure roller 4 is installed between the two sets of first seated bearings 2, and a guide roller 5 is installed between the two sets of second seated bearings 3.

[0020] The first mounted bearing 2 includes a first bearing housing and a first ball bearing, with the first ball bearing installed in the first bearing housing.

[0021] The second bearing 3 includes a second bearing housing and a second ball bearing, with the second ball bearing installed in the second bearing housing.

[0022] The expansion roller mounting structure also includes two sets of height-adjustable movable supports 7 and one expansion roller 8. Each set of movable supports 7 includes an upper support block 71, a lower support block 72, a mounting block 73, four support screws 74, a third bearing seat 75, and a third ball bearing 76. The end of the support screw 74 away from the mounting block 73 is provided with an internal hexagonal hole 742.

[0023] The movable bracket 7 is installed on the inner side of the fixed bracket plate 1 by bolts 6 for installing the first bearing 2 and the second bearing 3. Specifically, the upper support block 71 is installed on the inner side of the fixed bracket plate 1 by bolts 6 for installing the first bearing 2, and the lower support block 72 is installed on the inner side of the fixed bracket plate 1 by bolts 6 for installing the second bearing 3.

[0024] Two support screws 74 perpendicular to the lower support block 72 are screwed onto the lower support block 72, and two support screws 74 perpendicular to the upper support block 71 are screwed onto the upper support block 71. The mounting block 73 is sandwiched between the support screws 74 screwed onto the lower support block 72 and the support screws 74 screwed onto the upper support block 71. The height of the mounting block 73 can be adjusted by rotating the support screws 74.

[0025] To improve the stability of the mounting block 73 clamped between the support screw 74, two spherical limiting grooves 731 are provided at the top and bottom of the mounting block 73, and the end of the support screw 74 that contacts the mounting block 73 is a hemispherical pressing block 741, which is inserted into the limiting groove 731.

[0026] The shafts at both ends of the expansion roller 8 are respectively installed in two sets of movable brackets 7. Specifically, the third bearing housing 75 is installed inside the mounting block 73, and the third ball bearing 76 is sandwiched between the third bearing housing 75 and the mounting block 73. The shaft of the expansion roller 8 is interference-fitted into the inner ring of the third ball bearing 76.

[0027] A circular clearance groove 732 is provided in the center of the mounting block 73. The inner diameter of the clearance groove 732 is larger than the outer diameter of the inner ring of the third ball bearing 76. The clearance groove 732 avoids obstructing the rotation of the inner ring of the third ball bearing 76.

[0028] The movable bracket is installed inside the fixed bracket plate by bolts for installing the first and second seated bearings. Then, the shafts at both ends of the expansion roller are installed in the two sets of movable brackets respectively. There is no need to cut, weld, or drill to modify the original equipment, which facilitates the installation and disassembly of the expansion roller.
