Description

Technical Field

[0001] This utility model belongs to the field of glass production and conveying technology, and specifically relates to a side guide wheel for a glass substrate conveying line. Background Technology

[0002] The guide rollers on the glass substrate conveyor line are core components ensuring the precise transport of glass substrates in panel manufacturing. They prevent substrates from deviating or colliding during high-speed transport by limiting and guiding them, directly affecting production yield and equipment stability. However, traditional rigid support structures cannot effectively absorb impact when glass substrates are transported at an angle (such as 5°), resulting in hard collisions between the substrate and the guide rollers, which can easily cause micro-cracks or even fragments at the edges. Moreover, the fixed damping design usually cannot adapt to changes in substrate size, transport speed, or vibration amplitude, and is prone to guide roller oscillation and deviation due to vibration imbalance, exacerbating substrate position deviation and abnormal equipment vibration. In addition, the guide rollers need to be replaced as a whole after wear, resulting in long downtime and high spare parts costs. Summary of the Invention

[0003] To address the problems of insufficient buffering and poor damping adjustment flexibility in existing edge guide wheels, a new edge guide wheel for glass substrate conveying lines is proposed. This utility model provides the following technical solution:

[0004] A guide wheel for a glass substrate conveying line includes a fixed base for connecting a frame. A hinge plate is fixedly connected to the fixed base, and a hinge hole is provided on the hinge plate. A support rod is hinged to the hinge hole through a hinge shaft. A guide wheel assembly is mounted on the support rod. Adjustment components for adjusting the swing damping of the support rod are symmetrically arranged on both radial sides of the hinge shaft. The adjustment components include a screw seat, a screw, a sleeve, and a compression spring. The screw seat is fixedly connected to the fixed base, the screw is threadedly connected to the screw seat, the sleeve is fixedly connected to the end of the screw near the support rod, and the compression spring is disposed in the sleeve with one end abutting against the bottom wall of the sleeve and the other end abutting against the support rod.

[0005] Preferably, the upper end of the support rod is fixedly connected to a pin, and the bottom of the guide wheel assembly is provided with a slot. The cross-section of both the pin and the slot is a regular polygon, and the pin is inserted into the slot.

[0006] Preferably, a limiting platform is provided around the pin, and a buffer pad is provided on the outer sleeve of the pin. The upper and lower ends of the buffer pad abut against the guide wheel assembly and the limiting platform, respectively.

[0007] Preferably, the support rod is provided with a positioning groove for installing a compression spring.

[0008] Preferably, a limiting cylinder is fixedly connected to both the positioning groove and the sleeve, and the compression spring is sleeved on the outside of the limiting cylinder.

[0009] Preferably, the guide wheel assembly includes a support shaft, on which a limiting platform and an annular groove are provided. A bearing is installed on the limiting platform, and an upper end cover and a lower end cover are respectively connected to the upper and lower sides of the bearing. An elastic retaining ring for limiting the bearing is embedded in the annular groove.

[0010] Preferably, the upper end cover is fitted with a wear-resistant ring.

[0011] Preferably, the fixed base is provided with a limiting hole, and the lower end of the support rod can be detachably connected to a counterweight after passing through the limiting hole.

[0012] Preferably, the fixed base includes two parallel vertical plates, which are vertically connected to a horizontal plate. The hinge hole and screw seat are both provided on the horizontal plate. The horizontal plate is connected to the middle of the vertical plate. The vertical plate has mounting holes for connecting the frame on both the upper and lower sides of the horizontal plate. The mounting holes are arranged in a rectangular shape.

[0013] Preferably, a rib is fixedly connected between the vertical plate and the horizontal plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The stepless adjustment function of the swing damping of the support rod is realized through the adjustment components arranged symmetrically on both sides. The operator can precisely control the compression amount of the compression spring by rotating the screw, thereby dynamically matching different glass substrate thicknesses, conveying speeds and process requirements.

[0016] 2. The dual compression spring layout forms a two-way buffer mechanism, ensuring that the support rod is subjected to balanced force, effectively suppressing the transmission of abnormal vibration to the guide wheel assembly, and ensuring the stability of the glass substrate conveying process. It is especially suitable for production scenarios with multiple varieties and changing working conditions.

[0017] 3. The symmetrically arranged positioning grooves on both sides of the support rod and the limiting cylinder inside the sleeve form a ring-shaped guide structure, which makes the lateral deviation of the compression spring smaller, reduces abnormal wear caused by spring deviation, and improves its stability.

[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] like Figure 1-3 As shown, a guide wheel for a glass substrate conveyor line includes a fixed base 1 for connecting to a frame. A hinge plate 111 is fixedly connected to the fixed base 1. The hinge plate 111 has a hinge hole. A support rod 2 is hinged to the hinge hole through a hinge shaft 1111. A guide wheel assembly 3 is mounted on the support rod 2. Adjustment components 4 for adjusting the swing damping of the support rod 2 are symmetrically arranged on both radial sides of the hinge shaft 1111. The adjustment components 4 include a screw seat 41, a screw 42, a sleeve 43, and a compression spring 44. The screw seat 41 is fixedly connected to the fixed base 1. The base 1 and screw 42 are threadedly connected to screw seat 41. Sleeve 43 is fixedly connected to one end of screw 42 near support rod 2. Compression spring 44 is set in sleeve 43, with one end abutting against the bottom wall of sleeve 43 and the other end abutting against support rod 2. By rotating screw 42, the compression amount of compression spring 44 can be changed, thereby realizing stepless adjustment of damping force on support rod 2 to adapt to different working conditions. At the same time, the symmetrical layout of double compression springs 44 can provide bidirectional buffering, ensuring that the force is balanced when support rod 2 swings and effectively suppressing abnormal vibration.

[0024] Furthermore, a pin 21 is fixedly connected to the upper end of the support rod 2, and a slot 311 is provided at the bottom of the guide wheel assembly 3. Both the pin 21 and the slot 311 have square cross-sections. The pin 21 can be inserted into the slot 311 to achieve rotational limitation, and the entire guide wheel assembly 3 can be quickly replaced.

[0025] The guide wheel assembly 3 can directly adopt the existing structure, and can be modified by adding a slot 311. In this embodiment, the guide wheel assembly 3 includes a support shaft 31, on which a limiting platform 312 and an annular groove 313 are provided. A bearing 32 is installed on the limiting platform 312. An upper end cover 33 and a lower end cover 34 are respectively connected to the upper and lower sides of the bearing 32. The upper end cover 33 and the lower end cover 34 are threaded together. An elastic retaining ring 36 for limiting the bearing 32 is embedded in the annular groove 313. The limiting platform 312 and the elastic retaining ring 36 form a double axial fixing structure to ensure the operating accuracy of the bearing 32. The combined design of the upper end cover 33 and the lower end cover 34 forms a closed lubrication chamber to reduce the risk of grease leakage. A wear-resistant ring 35 is provided on the upper end cover 33 to improve durability, and the wear-resistant ring 35 can be replaced separately.

[0026] Furthermore, a limiting platform 211 is provided on the periphery of the pin 21, and a buffer pad 212 is provided on the outer sleeve of the pin 21. The upper and lower ends of the buffer pad 212 abut against the support shaft 31 and the limiting platform 211 respectively. The elastic buffer pad 212 can absorb the vertical impact energy and effectively protect the connection part from hard impact damage.

[0027] Furthermore, the support rod 2 is symmetrically provided with positioning grooves 22 for installing compression springs 44 on both sides. Limiting cylinders 221 are fixedly connected inside the positioning grooves 22 and the sleeve 43. The compression spring 44 is sleeved on the outside of the limiting cylinders 221, which can reduce the offset of the compression spring 44 during operation and improve its stability. At the same time, the annular space formed by the positioning grooves 22, the sleeve 43 and the limiting cylinders 221 can facilitate the quick positioning and installation and removal of the compression spring 44.

[0028] Furthermore, the fixed base 1 is provided with a limiting hole 112. The lower end of the support rod 2 passes through the limiting hole 112 and is detachably connected to a counterweight 5 to balance the torque above the hinge shaft 1111. Specifically, the upper middle part of the counterweight 5 is provided with a connecting hole, and the counterweight 5 is symmetrically provided with connecting grooves 51 on both horizontal sides. The lower end of the support rod 2 is provided with a connecting hole, and a connecting secondary hole is horizontally provided in the connecting groove 51. After the support rod 2 is inserted into the connecting hole, the connecting secondary hole and the connecting hole are kept coaxial, and then connected by bolts and nuts.

[0029] Furthermore, the fixed base 1 includes two parallel vertical plates 12 spaced apart, with the space between them providing horizontal space for the screw 42 to facilitate its adjustment. A horizontal plate 11 is vertically connected to both vertical plates 12. Hinge holes and screw seats 41 are located on the horizontal plate 11, which is connected to the middle of the vertical plates 12. Mounting holes 121 for connecting to the frame are provided on both the upper and lower sides of the horizontal plate 11 on the vertical plates 12. These mounting holes 121 are arranged in a rectangular pattern to improve the installation's firmness and the overall structural stability. To further improve the bending resistance of the horizontal plate 11 and the overall structural stability, a rib plate 13 is fixedly connected between the vertical plates 12 and the horizontal plate 11.
