Description

Technical Field

[0001] This application relates to the field of glass fiber production equipment technology, and in particular to a roller assembly / disassembly device. Background Technology

[0002] Graphite rollers are an important auxiliary tool in the production of glass fiber. However, graphite rollers are prone to wear and therefore need to be replaced regularly. A graphite roller generally consists of a roller shaft and a cylinder fitted onto the roller shaft, with the cylinder fixedly connected to the roller shaft by fasteners such as nuts.

[0003] Because the roller shaft experiences less wear than the roller cylinder, typically only the roller cylinder needs to be replaced, and a new roller cylinder is then installed on the roller shaft. Currently, both the disassembly and installation of the roller cylinder are done manually, consuming a significant amount of manpower and time, resulting in low production efficiency. Furthermore, manual operation may cause wear or damage to the roller cylinder and may also pose certain safety risks to the operators. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0041] This application provides a roller shaft disassembly and assembly device, including a frame, a disassembly and assembly device mounted on the frame, and an ejection device. The disassembly and assembly device includes a sleeve and a first drive mechanism connected to the sleeve. The sleeve is fitted onto a fastener, which is used to connect a workpiece to a roller and a roller shaft. The first drive mechanism drives the sleeve to rotate, thereby disassembling or installing the fastener. The ejection device ejects the roller shaft from or into the roller. This allows for more convenient and labor-saving disassembly and assembly of the roller shaft and roller, reducing manual labor intensity and improving production efficiency.

[0042] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0043] like Figure 1 and Figure 2 As shown, an exemplary embodiment of this application provides a roller assembly / disassembly device, including a frame 1, an assembly / disassembly device 2 and an ejection device 3 disposed on the frame 1. The assembly / disassembly device 2 includes a sleeve 21 and a first drive mechanism 22 connected to the sleeve 21. The sleeve 21 is sleeved on a fastener 30, which is used to connect the roller 10 and the roller shaft 20 of the workpiece 100. The first drive mechanism 22 is used to drive the sleeve 21 to rotate so as to disassemble or install the fastener 30. The ejection device 3 is disposed on one side of the assembly / disassembly device 2 and is used to eject the roller shaft 20 from the roller 10 or to eject the roller shaft 20 into the roller 10.

[0044] In this embodiment, the workpiece 100 is placed on the frame 1, and the sleeve 21 is fitted onto the fastener 30. The sleeve 21 is driven to rotate in a first direction (e.g., counterclockwise) by the first drive mechanism 22 to loosen and disassemble the fastener 30. The roller shaft 20 is ejected from the roller 10 by the ejection device 3 to separate the roller shaft 20 from the roller 10. After the roller 10 is removed, a new roller 10 is placed on the frame 1. The roller shaft 20 is pushed into the roller 10 by the ejection device 3, and the fastener 30 is placed on the sleeve 21 (or the fastener 30 is placed at the end of the roller shaft 20). The sleeve 21 is driven to rotate in a second direction (e.g., clockwise) by the first drive mechanism 22 to tighten and install the fastener 30. Thus, the roller shaft 20 and the roller 10 can be fixedly connected.

[0045] The workpiece 100 can be, for example, a graphite roller, which includes a roller shaft 20 and a roller 10 sleeved on the roller shaft 20. The fastener 30 can be, for example, a nut. The roller shaft 20 has threaded structures at both ends, and two nuts are threadedly connected to the threaded structures at both ends of the roller shaft 20, with the nuts abutting against the ends of the roller 10 to achieve the connection between the roller shaft 20 and the roller 10. The inner wall shape of the sleeve 21 matches the outer wall shape of the fastener 30. For example, when the fastener 30 is a hexagonal nut, the end of the sleeve 21 is set as a hexagonal groove. In addition, an operating protective plate can be installed on the frame 1 to improve the safety of the overall device.

[0046] In an exemplary embodiment, the first drive mechanism 22 includes a support structure 221 and a drive motor 222 disposed on the support structure 221. The drive motor 222 is connected to the sleeve 21 via a belt drive assembly 223.

[0047] In this embodiment, the support structure 221 can be, for example, a support plate; the belt drive assembly 223 includes a drive wheel 2231 connected to the output shaft of the drive motor 222 and a driven wheel 2233 connected to the drive wheel 2231 via a belt 2232; the first drive mechanism 22 also includes a rotating shaft 23 fixedly connected to the driven wheel 2233 and a spring 24 sleeved on the rotating shaft 23, and a sleeve 21 sleeved on the rotating shaft 23. The drive motor 222 drives the drive wheel 2231 to rotate, thereby driving the driven wheel 2233 to rotate. The driven wheel 2233 drives the sleeve 21 to rotate via the rotating shaft 23. By setting the spring 24, the rotation of the rotating shaft 23 can be buffered, effectively reducing the impact and vibration when the rotating shaft 23 rotates, which is beneficial to protecting the overall device and can reduce the impact damage of the disassembly and assembly device 2 to the graphite roller.

[0048] In an exemplary embodiment, the disassembly and assembly device 2 further includes a second drive mechanism 25 connected to the first drive mechanism 22, the second drive mechanism 25 being used to drive the sleeve 21 to move toward or away from the fastener 30.

[0049] In this embodiment, the second drive mechanism 25 drives the sleeve 21 to move in a direction close to or away from the fastener 30, so that the sleeve 21 can remove the fastener 30 from the roller 20. The second drive mechanism 25 is mounted on the frame 1, and the support structure 221 is mounted on the frame 1 via a linear guide rail. The second drive mechanism 25 is fixedly connected to the support structure 221, and by driving the support structure 221 to move, it moves the sleeve 21 located on the support structure 221. The second drive mechanism 25 can be, for example, a hydraulic cylinder.

[0050] In one exemplary embodiment, the ejection device 3 includes a bracket 31 disposed on the frame 1 and an ejection mechanism 32 disposed on the bracket 31.

[0051] In this embodiment, the ejector mechanism 32 can be raised by the bracket 31, so that the axis of the push rod of the ejector mechanism 32 is on the same horizontal plane as the axis of the roller 20, so that the roller 20 can be ejected or inserted by the ejector mechanism 32. The ejector mechanism 32 can be, for example, a push rod hydraulic cylinder. The bracket 31 has an "L" shaped structure, and a through hole 311 is provided on the vertical section of the bracket 31. The axis of the through hole 311 coincides with the axis of the roller 20. The push rod of the push rod hydraulic cylinder passes through the through hole 311 to eject or insert the roller 20.

[0052] In an exemplary embodiment, the roller assembly / disassembly device further includes a switching device 4, which includes a sliding structure 41 and a third drive mechanism 42 disposed on the frame 1. The assembly / disassembly device 2 and the ejection device 3 are both disposed on the sliding structure 41. The third drive mechanism 42 is connected to the sliding structure 41 and is used to drive the sliding structure 41 to move horizontally along the axis perpendicular to the roller 20.

[0053] In this embodiment, the third drive mechanism 42 is mounted on the frame 1, and the sliding structure 41 is mounted on the frame 1 via a linear guide rail. The third drive mechanism 42 is fixedly connected to the sliding structure 41. By driving the sliding structure 41 to move horizontally along the axis perpendicular to the roller 20, the relative positions of the disassembly / assembly device 2, the ejection device 3, and the workpiece 100 are adjusted. The sliding structure 41 can be a sliding plate, and the third drive mechanism 42 can be, for example, a cylinder.

[0054] In an exemplary embodiment, the switching device 4 further includes a first limiting structure 43, which is disposed on the sliding structure 41 and is used to make the axes of the disassembly and assembly device 2, the ejection device 3 and the roller 20 lie on the same horizontal plane.

[0055] In this embodiment, by setting the first limiting structure 43, the distance between the sleeve 21 of the disassembly and assembly device 2, the ejection mechanism 32 of the ejection device 3, and the sliding structure 41 can be adjusted so that the axis of the sleeve 21, the ejection mechanism 32, and the roller shaft 20 are located on the same horizontal plane, thereby improving the accuracy of disassembly and assembly of the fastener 30 and the roller shaft 20. The first limiting structure 43 can be, for example, a limiting stop.

[0056] In an exemplary embodiment, the switching device 4 further includes a second limiting structure 44, which is disposed at one end of the sliding structure 41 near the workpiece 100, and is used to limit the movement position of the disassembly / assembly device 2 and the ejection device 3.

[0057] In this embodiment, the second limiting structure 44 is disposed at one end of the sliding structure 41 near the workpiece 100, that is, the second limiting structure 44 is disposed at the displacement endpoint of the disassembly / assembly device 2 and the ejection device 3, which can limit the moving position of the disassembly / assembly device 2 and the ejection device 3, thereby improving the accuracy of disassembly / assembly of the fastener 30 and the roller 20. The second limiting structure 44 can be, for example, a position sensor.

[0058] In an exemplary embodiment, the switching device 4 further includes a third limiting structure, which is disposed at one end of the frame 1 away from the third drive mechanism 42, and is used to limit the movement position of the sliding structure 41.

[0059] In this embodiment, a third limiting structure (not shown in the figure) is disposed at the end of the frame 1 away from the drive mechanism, that is, the third limiting structure is disposed at the displacement endpoint of the sliding structure 41, which can limit the movement position of the sliding structure 41 to prevent the sliding structure 41 from sliding off the frame 1. The third limiting structure can be, for example, a vertical bearing seat, which can limit the movement distance of the third drive mechanism 42.

[0060] In one exemplary embodiment, the roller assembly / disassembly device further includes a fixing device 5, which can abut against the roller 10 to fix the roller 10 to the frame 1.

[0061] In this embodiment, the roller 10 is fixed to the frame 1 by the fixing device 5, which can reduce the shaking during the assembly and disassembly of the fastener 30. The fixing device 5 can be, for example, an elbow clamp, and its specific structure can adopt the relevant structure in the prior art, which will not be described in detail here. Since the graphite roller is more brittle than materials such as metal pipes, in order to avoid wear on the graphite roller by the elbow clamp and to improve the stability of the clamping, when fixing the graphite roller with the elbow clamp, a shim block can be set on the frame 1 to adjust the relative height between the clamping head of the elbow clamp and the graphite roller, and to adjust the relative position between the elbow clamp and the graphite roller, so that the clamping head of the elbow clamp can clamp the middle of the roller 10 of the graphite roller.

[0062] In one exemplary embodiment, a support block 11 for supporting the bottom of the workpiece 100 is provided on the frame 1.

[0063] In this embodiment, the support block 11 has a "V" shaped structure, which can support the bottom of the roller 10. With the cooperation of the fixing device 5, the stability between the roller 10 and the frame 1 can be improved. The number of support blocks 11 is not limited; it can be one, two, etc., for example... Figure 2 There are two central support blocks 11.

[0064] In an exemplary embodiment, the frame 1 is provided with a receiving groove 12 for supporting the end of the workpiece 100.

[0065] In this embodiment, the end of the workpiece 100 can be supported by the receiving groove 12 to improve the stability between the roller 10 and the frame 1.

[0066] The frame 1 includes a base frame 13 and two first support plates 14 located at both ends of the base frame 13. Two first rectangular tubes 15 are arranged between the two first support plates 14. A switching base plate 16 is provided at the top of the two first rectangular tubes 15, and a sliding structure 41 is mounted on the switching base plate 16 via a linear guide rail. A second support plate 17 is arranged between the two first rectangular tubes 15, and receiving grooves 12 are respectively provided on the second support plate 17 and one of the first support plates 14. Two second rectangular tubes 18 are arranged between the second support plate 17 and one of the first support plates 14, and a fixing device 5 is provided on one of the second rectangular tubes 18. Two third rectangular tubes 19 are provided at the bottom of the two second rectangular tubes 18, and a support block 11 is provided on the third rectangular tubes 19. This frame 1 structure improves the overall stability of the roller assembly / disassembly equipment.

[0067] An exemplary embodiment of this application provides the working process of a roller assembly / disassembly device. For ease of description, the workpiece 100 in this embodiment is a graphite roller, and the fastener 30 is a nut.

[0068] The graphite roller is placed on the frame 1, supported by the support block 11, supported by the receiving groove 12, and fixed by the fixing device 5. The switching device 4 is activated, and the sliding structure 41 is moved by the third drive mechanism 42 to adjust the relative position of the sleeve 21 on the sliding structure 41 and the graphite roller, so that the axis of the sleeve 21 coincides with the axis of the roller shaft 20. The support structure 221 is moved towards the nut by the second drive mechanism 25, so that the sleeve 21 is fitted onto the nut. The sleeve 21 is rotated by the first drive mechanism 22, and the support structure 221 is moved away from the nut by the second drive mechanism 25, so that the nut is disassembled and separated from the roller shaft 20. Then, the sliding structure 41 is moved by the third drive mechanism 42 to adjust the relative position of the ejector device 3 on the sliding structure 41 and the graphite roller, so that the axis of the push rod of the ejector device 3 coincides with the axis of the roller 20; the ejector device 3 is activated to eject the roller 20 from the roller 10, so as to separate the roller 20 from the roller 10; in this way, the disassembly of the old roller 10 is completed.

[0069] When a new roller 10 needs to be installed on roller shaft 20, the new roller 10 is placed on frame 1 and fixed by fixing device 5; the relative position of ejector device 3 on sliding structure 41 and graphite roller is adjusted by switching device 4 so that the axis of push rod of ejector device 3 coincides with the axis of roller shaft 20; roller shaft 20 is installed on ejector device 3 and ejector device 3 pushes roller shaft 20 into roller 10 by push rod; then the relative position of sleeve 21 on sliding structure 41 and graphite roller is adjusted by switching device 4 so that the axis of sleeve 21 coincides with the axis of roller shaft 20; nut is placed on sleeve 21; second drive mechanism 25 drives support structure 221 to move toward the nut; first drive mechanism 22 drives sleeve 21 to rotate in the opposite direction so that nut is installed on roller shaft 20 and nut abuts against end of roller 10 to achieve assembly of roller shaft 20 and roller 10.

[0070] In summary, the roller assembly / disassembly equipment of this application enables the disassembly and installation of the roller shaft 20 of the graphite roller, effectively solving the problems of complex, time-consuming, and poor installation quality in the graphite roller installation process. The equipment replaces manual operation, reducing labor intensity, improving accessory replacement efficiency, and lowering labor costs. Furthermore, it avoids direct disassembly and assembly by operators, improving operational safety. In addition, the high-precision disassembly and assembly of the equipment effectively prevents damage to the graphite roller, significantly improving its quality after disassembly and assembly, extending its service life, and reducing costs.
