Description

Technical Field

[0001] This application belongs to the field of cover glass production equipment, and specifically relates to a cover glass traction roller clamping angle adjustment device. Background Technology

[0002] In the production of cover glass, the traction roller is a key device for achieving uniform speed extraction of the glass from the annealing furnace. Its contact with the glass directly affects the glass's shape (BOW), warpage, and overall forming quality. In existing technologies, traction roller devices are typically fixedly installed, making multi-directional angle adjustment impossible. This leads to poor contact issues during production due to various factors. On the one hand, uneven heating of the traction roller shaft leads to different expansion amounts in different sections, and there are assembly gaps in the clearance fit between the bearing and the shaft. In addition, uneven wear of the traction roller boss after long-term use and deformation of the boss caused by human wiping will reduce the contact area between the traction roller boss surface and the glass, and even cause fitting deviations such as "inward" or "outward". On the other hand, during the glass pulling and forming process, the traction roller needs to be adjusted downward in the vertical direction to adapt to the forming requirements, but the existing device cannot meet the adjustment in this direction, which further leads to quality problems such as glass cracks and poor forming. Utility Model Content

[0003] The purpose of this application is to provide a cover glass traction roller clamping angle adjustment device. This addresses the problems mentioned in the background art, such as poor adhesion between the existing traction roller and the glass due to factors like shaft thermal expansion, assembly gaps, boss wear, and deformation caused by manual wiping, leading to glass cracks, poor forming, and the need for frequent traction roller replacements that affect production progress and increase costs.

[0004] To achieve the above objectives, this application adopts the following technical solution: A cover glass traction roller clamping angle adjustment device includes a traction roller, a bearing seat, a composite plate, a composite plate base, and a connecting pin. The traction roller is assembled on the bearing housing via a bearing; The bearing housing is connected to the composite plate, and the bearing housing can rotate relative to the composite plate to adjust the left and right angles of the traction roller; The plywood and the plywood base are connected by a coupling pin, and the plywood can open and close relative to the plywood base to adjust the vertical angle of the traction roller; The assembly plate is equipped with a positioning pin, and the bearing seat is quickly positioned with the assembly plate through the positioning pin; The plywood base has a positioning groove in the middle for positioning and engaging with the traction roller base; The plywood and the plywood base are also provided with matching positioning grooves for positioning and engagement between the two.

[0005] In one possible implementation, the bearing housing and the composite plate are connected by bolts, and the bearing housing has an arc-shaped hole through which the bolts pass to fix the bearing housing and the composite plate; the arc-shaped hole is centered on the locating pin on the composite plate.

[0006] In one possible implementation, the left and right angle range of the bearing housing relative to the mating plate for rotation adjustment is -4° to 4°.

[0007] In one possible implementation, the tail end of the composite plate is provided with a threaded hole, and an adjusting bolt is fitted in the threaded hole. By tightening or loosening the adjusting bolt, the tail end of the composite plate can be raised or lowered, thereby realizing the opening and closing adjustment of the composite plate relative to the composite plate base.

[0008] In one possible implementation, the vertical angle range of the opening and closing adjustment of the laminate relative to the laminate base is 0° to -4°.

[0009] In one possible implementation, the positioning groove of the plywood base is adapted to the protrusion structure on the traction roller base, and the positioning and installation of the plywood base on the traction roller base is achieved through the cooperation of the positioning groove and the protrusion structure.

[0010] In one possible implementation, the positioning groove between the plywood and the plywood base includes a first positioning groove disposed at the bottom of the plywood and a second positioning groove disposed at the top of the plywood base, wherein the first positioning groove and the second positioning groove are adapted to achieve positioning and engagement between the plywood and the plywood base.

[0011] In one possible implementation, the bottom of the bearing housing is provided with at least one oblong hole, which is used to cooperate with bolts to realize the connection between the bearing housing and the assembly plate and to compensate for position during angle adjustment.

[0012] In one possible implementation, the number of arc-shaped holes is 2-4, and they are evenly distributed along the circumference of the locating pin.

[0013] In one possible implementation, there are two traction rollers, each mounted on a corresponding bearing seat via bearings, and the angles of the two traction rollers can be adjusted independently to achieve the fit between the boss surface and the glass.

[0014] Compared with the prior art, this application has the following beneficial effects: This application provides a cover glass traction roller clamping angle adjustment device. This device can adapt to positional deviations caused by factors such as uneven thermal expansion of the shaft, assembly clearance between the bearing and the shaft, wear of the boss, and deformation caused by human wiping during production. By flexibly adjusting the angle of the traction roller, it ensures that the boss surface of the traction roller is in close contact with the glass, reducing problems such as glass cracks and poor forming caused by poor contact. At the same time, the device can be directly connected to the original traction roller base without modifying other parts. While ensuring the adjustment function, it reduces the cost of modifying existing production equipment, which is conducive to maintaining production continuity and reducing production interruptions and cost increases caused by replacing traction rollers.

[0015] In one possible implementation, an arc-shaped hole centered on a locating pin is used in conjunction with a bolt connection, which makes the left and right angle adjustment of the bearing housing more precise and stable within the range of -4° to 4°. This can effectively correct the deviation in the contact between the traction roller and the glass caused by the thermal expansion of the shaft, assembly gaps, or wear of the boss, ensuring that the boss surface is in close contact with the glass and reducing quality problems such as glass cracks.

[0016] In one possible implementation, the vertical angle is limited to 0° to -4°, which can meet the forming requirements of the traction roller adjusting downward during the glass pulling process, while avoiding abnormal stress on the glass due to excessive angle, effectively reducing glass cracks and poor forming, and ensuring product quality stability.

[0017] In one possible implementation, the lifting or lowering of the tail end of the plywood is directly driven by adjusting bolts, and the opening and closing angle can be adjusted without disassembling parts. This is convenient and efficient, and can quickly respond to the adjustment needs of the traction roller angle in production, reduce downtime, and ensure production continuity.

[0018] In one possible implementation, the independent adjustment design of the two traction rollers can address individual deviations caused by wear, expansion, etc., ensuring that the boss surface of each traction roller can fit tightly with the glass, avoiding poor overall fit due to limited adjustment on one side, and further improving the quality of glass forming.

Obviously, the described embodiments are only some embodiments of this application, and 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.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this application discloses a cover glass traction roller clamping angle adjustment device, which may include a traction roller 1, a bearing seat 4, a composite plate 5, a composite plate base 3, and a connecting pin 7.

[0028] The traction roller 1 is mounted on the bearing housing 4 via a bearing. Optionally, the positioning groove at the bottom of the plywood base 3 can be matched with the protrusion of the traction roller 1 base to achieve overall positioning and installation.

[0029] The bearing seat 4 is connected to the composite plate 5, and the bearing seat 4 can rotate relative to the composite plate 5 to adjust the left and right angles of the traction roller 1.

[0030] Optionally, one side of the plywood 5 is hinged to the plywood base 3 via a connecting pin 7, and the other side is engaged and fixed with the concave positioning groove of the plywood base 3 via a matching convex positioning groove.

[0031] The plywood 5 is connected to the plywood base 3 by a connecting pin 7. The plywood 5 can open and close relative to the plywood base 3 to adjust the vertical angle of the traction roller 1.

[0032] The plywood 5 is provided with a positioning pin 6. The bearing seat 4 is quickly positioned with the plywood 5 through the positioning pin 6. The plywood base 3 is provided with a positioning groove in the middle for positioning and cooperating with the base of the traction roller 1. The plywood 5 and the plywood base 3 are also provided with a matching positioning groove for positioning and cooperating between the two.

[0033] Optionally, a cylindrical locating pin 6 is welded to the top of the plywood base 3, and an arc-shaped hole 8 with the locating pin 6 as the center is opened on the bearing seat 4. Bolts pass through the arc-shaped hole 8 to fix the bearing seat 4 to the plywood base 3.

[0034] Two traction rollers 1 are respectively assembled on corresponding bearing seats 4 via deep groove ball bearings, with the boss surfaces facing each other to clamp the glass 2.

[0035] In this embodiment, the device can adapt to positional deviations of the traction roller 1 caused by factors such as uneven thermal expansion of the shaft, assembly clearance between the bearing and the shaft, wear of the boss, and deformation caused by manual wiping during production. By flexibly adjusting the angle of the traction roller 1, it ensures that the boss surface of the traction roller 1 is in close contact with the glass 2, reducing problems such as cracks and poor forming of the glass 2 caused by poor contact. At the same time, the device can be directly connected to the original traction roller 1 base without modifying other parts. While ensuring the adjustment function, it reduces the modification cost of existing production equipment, which is conducive to maintaining the continuity of production and reducing production interruptions and cost increases caused by replacing the traction roller 1.

[0036] In one possible embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, the bearing housing 4 is connected to the composite plate 5 by bolts. The bearing housing 4 has an arc-shaped hole 8. The bolt passes through the arc-shaped hole 8 to fix the bearing housing 4 and the composite plate 5. The opening direction of the arc-shaped hole 8 is centered on the positioning pin 6 on the composite plate 5.

[0037] Specifically, the bearing seat 4 is connected to the composite plate 5 by bolts. The bearing seat 4 has an arc-shaped hole 8, and the direction of the arc-shaped hole 8 is centered on the positioning pin 6 on the composite plate 5. When it is necessary to adjust the left and right angles of the traction roller 1, the bolts are loosened, and the bearing seat 4 can rotate around the positioning pin 6 along the direction of the arc-shaped hole 8. Its rotation range is limited to 4° on the left and 4° on the right. After adjustment, the bolts are tightened to fix the bearing seat 4 and the composite plate 5, so as to realize the corresponding adjustment of the left and right angles of the traction roller 1.

[0038] In this embodiment, the arc-shaped hole 8 with the positioning pin 6 as the center is connected with bolts, so that the left and right angle adjustment of the bearing seat 4 in the range of -4° to 4° is more precise and stable. This can effectively correct the deviation between the traction roller 1 and the glass 2 caused by the thermal expansion of the shaft, assembly gap or wear of the boss, ensure that the boss surface is in close contact with the glass 2, and reduce quality problems such as cracks in the glass 2.

[0039] In one possible embodiment, the left and right angle range of the bearing housing 4 relative to the mating plate 5 is -4° to 4°.

[0040] Specifically, the bearing housing 4 is bolted to the composite plate 5 via a bottom slotted hole, and the positioning pin 6 on the composite plate 5 is inserted into the middle circular hole of the bearing housing 4 for positioning. When it is necessary to adjust the left and right angles of the traction roller 1, the connecting bolts are loosened, and the bearing housing 4 can rotate around the positioning pin 6. The rotation range is limited to 4° to the left and 4° to the right by the cooperation of the slotted hole and the bolt. After adjustment, the bolts are tightened to fix it, thereby driving the traction roller 1 to adjust the corresponding angle in the left and right directions. Other larger angles can also be adjusted as needed.

[0041] In this embodiment, the left and right angle adjustment range of the bearing seat 4 is limited to -4° to 4°, which can accurately correct the "inward" or "outward" deviation of the traction roller 1 caused by uneven thermal expansion of the shaft, assembly gap or wear of the boss, ensure that the boss surface of the traction roller 1 is in close contact with the glass 2, reduce the cracks in the glass 2 caused by insufficient contact surface, and improve production quality.

[0042] In one possible embodiment, the tail end of the composite plate 5 is provided with a threaded hole, and an adjusting bolt is fitted in the threaded hole. By tightening or loosening the adjusting bolt, the tail end of the composite plate 5 can be raised or lowered, thereby realizing the opening and closing adjustment of the composite plate 5 relative to the composite plate base 3.

[0043] Optionally, the tail end of the composite plate 5 is provided with a threaded hole, which mates with an adjusting bolt. The end of the bolt's threaded end contacts the top surface of the composite plate base 3. When it is necessary to adjust the opening angle of the composite plate 5 relative to the composite plate base 3, tightening the adjusting bolt clockwise will push the tail end of the composite plate 5 upward, causing the composite plate 5 to rotate upward around the connecting pin 7; loosening the adjusting bolt counterclockwise will cause the tail end of the composite plate 5 to fall downward under its own weight, thereby realizing the opening and closing adjustment between the composite plate 5 and the composite plate base 3.

[0044] In this embodiment, the lifting or lowering of the tail end of the composite plate 5 is directly driven by adjusting the bolts, and the opening and closing angle adjustment can be completed without disassembling the parts. The operation is convenient and efficient, and it can quickly respond to the adjustment needs of the traction roller 1 angle in production, reduce downtime, and ensure production continuity.

[0045] In one possible embodiment, the vertical angle range of the opening and closing adjustment of the plywood 5 relative to the plywood base 3 is 0° to -4°.

[0046] Optionally, when the plywood 5 is opened and closed relative to the plywood base 3, the vertical angle is limited to between 0° and -4°. For example, by controlling the screwing depth of the adjusting bolt, the maximum descent of the tail end of the plywood 5 corresponds to a vertical angle of -4°, ensuring that the adjustment range precisely matches the requirements of the glass 2's pull-down forming.

[0047] In this embodiment, the vertical angle is limited to 0° to -4°, which can meet the forming requirements of the traction roller 1 adjusting downward during the glass 2 pulling process, and avoid abnormal force on the glass 2 due to excessive angle, effectively reducing cracks and poor forming of the glass 2, and ensuring product quality stability.

[0048] In one possible embodiment, the positioning groove of the plywood base 3 is adapted to the protrusion structure on the traction roller 1 base, and the positioning and installation of the plywood base 3 on the traction roller 1 base is achieved through the cooperation of the positioning groove and the protrusion structure.

[0049] Optionally, the bottom of the plywood base 3 is provided with an elongated positioning groove, the cross-sectional shape of which matches the protruding structure on the traction roller 1 base. During installation, the positioning groove of the plywood base 3 is aligned with the protruding structure on the traction roller 1 base and inserted, which quickly achieves the positioning of the plywood base 3 on the traction roller 1 base, and then it is further fixed by bolts.

[0050] In this embodiment, the matching design of the positioning groove and the protrusion structure can quickly and accurately position the plywood base 3 on the traction roller 1 base, avoid misalignment during installation, ensure the overall assembly accuracy of the device, simplify the installation process, and improve the efficiency of equipment assembly or maintenance.

[0051] In one possible embodiment, the positioning groove between the plywood 5 and the plywood base 3 includes a first positioning groove disposed at the bottom of the plywood 5 and a second positioning groove disposed at the top of the plywood base 3. The first positioning groove and the second positioning groove are adapted to achieve positioning and engagement between the plywood 5 and the plywood base 3.

[0052] Optionally, the plywood 5 has a first positioning groove at its bottom, and the plywood base 3 has a second positioning groove at a corresponding position at its top. The size and shape of the first positioning groove are perfectly matched with the second positioning groove. When the plywood 5 and the plywood base 3 are assembled, the first positioning groove is embedded in the second positioning groove. When the opening and closing angle is adjusted, the two slide relative to each other along the groove, and after adjustment, they fit tightly together.

[0053] In this embodiment, the cooperation between the first positioning groove and the second positioning groove can effectively limit the lateral displacement of the plywood 5 and the plywood base 3 during the adjustment process, ensure the accuracy of the opening and closing angle adjustment, enhance the stability of the connection between the two, and reduce the impact of vibration during operation on the angle of the traction roller 1.

[0054] In one possible embodiment, the bottom of the bearing housing 4 is provided with at least one oblong hole, which is used to cooperate with bolts to realize the connection between the bearing housing 4 and the composite plate 5 and to compensate for position during angle adjustment.

[0055] Optionally, the bearing housing 4 has four oblong holes at its bottom, with the length of the oblong holes extending along the rotational adjustment direction of the bearing housing 4. The connecting bolts pass through the oblong holes and connect to the threaded holes on the composite plate 5. When the bearing housing 4 rotates around the locating pin 6 to adjust the angle, the oblong holes provide movement space for the bolts, preventing the bolts from obstructing the adjustment. After adjustment, tightening the bolts will fix the bearing housing 4 to the composite plate 5.

[0056] In this embodiment, the design of the waist-shaped hole not only meets the position compensation requirements when the bearing seat 4 is adjusted, but also enables the bearing seat 4 to be firmly connected to the assembly plate 5 through bolts, preventing the bearing seat 4 from loosening and shifting after adjustment, ensuring the stability of the traction roller 1 angle, and guaranteeing the bonding effect of the glass 2.

[0057] In one possible embodiment, the number of arc-shaped holes 8 is 2-4, and they are evenly distributed along the circumference of the locating pin 6.

[0058] Optionally, the top positioning pin 6 of the plywood base 3 has three arc-shaped holes 8 evenly distributed around its circumference. The center of each arc-shaped hole 8 coincides with the axis of the positioning pin 6, and the arc length of the arc-shaped hole 8 corresponds to the horizontal adjustment angle range. A bolt is inserted into each arc-shaped hole 8, and the bolt engages with the threaded hole of the plywood base 3. During adjustment, the bearing seat 4 can be rotated by loosening the bolt, and locked after it is in place.

[0059] In this embodiment, 2-4 evenly distributed arc-shaped holes 8 can evenly distribute the locking force of the bolts, preventing the bearing seat 4 from tilting or deforming due to uneven force, thus enhancing the structural stability of the device. At the same time, the multiple bolts can improve the firmness of the connection between the bearing seat 4 and the composite base 3, ensuring the accuracy and reliability of the horizontal angle adjustment.

[0060] In one possible embodiment, there are two traction rollers 1, which are respectively mounted on corresponding bearing seats 4 via bearings, and the angles of the two traction rollers 1 can be adjusted independently to achieve the fit between the boss surface and the glass 2.

[0061] Optionally, the device may include two traction rollers 1, each with an independent bearing seat 4 mounted at both ends, and each traction roller 1 having an independent structure for components such as the mating plate 5 and the mating plate base 3. When the left traction roller 1 experiences a misalignment due to wear, the horizontal angle of its corresponding bearing seat 4 and the vertical angle of the mating plate 5 can be adjusted independently; similarly, the right traction roller 1 can be adjusted independently to ensure that the boss surfaces of the two traction rollers 1 are tightly fitted to both sides of the glass 2.

[0062] In this embodiment, the independent adjustment design of the two traction rollers 1 can specifically solve the individual deviations caused by wear, expansion, etc., and ensure that the boss surface of each traction roller 1 can be tightly fitted with the glass 2, avoiding poor overall fitting due to limited adjustment on one side, and further improving the forming quality of the glass 2.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
