Description

Technical Field

[0001] The utility model relates to the technical field of glass substrates, in particular to a traction roll replacement device. Background Art

[0002] Glass substrates are mainly produced in an annealing furnace by the overflow down-draw forming method. In this method, the glass substrates are pulled down by traction rolls to produce qualified thin-film liquid crystal panels. However, since the traction rolls are in contact with the glass substrates for a long time, the surfaces of the traction rolls are prone to wear after being used for a period of time, which in turn affects the quality of the glass substrates. Therefore, new traction rolls need to be replaced regularly.

[0003] Because the traction roll is more than 4 meters long and is in direct contact with high-temperature glass during operation, the temperature is very high. And during the replacement process, the traction roll cannot be knocked to cause damage to the effective surface. Therefore, currently, the replacement work of the traction roll requires multiple operators to operate simultaneously, but there are still great difficulties and relatively large potential safety hazards.

[0004] When replacing the traction roll, the operators at the far end and the near end respectively put sleeves on the traction roll, and slowly move the traction roll from the far end to the near end under unified command. After the whole traction roll is moved out of the annealing furnace, the operator at the near end is responsible for lifting the traction roll out of the forming area. At this time, the states of the operators at the near end are that one person holds the short sleeve to lift the traction roll, and the other two wear high-temperature gloves and lift the traction roll sent from the far end on both sides of the traction roll.

[0005] Since most of the operations in the replacement process need to be directly carried out by the operators by hand, the replacement time is long, the stability is poor, and there is a risk of scalding. At the same time, the output is affected. The reliability of the existing auxiliary devices for replacing the traction roll during the lifting process is not high, or the locking operation is relatively cumbersome. The operator's hands need to adjust the height, lock the height, and also need to support the traction roll, which increases the difficulty of replacing the traction roll.

[0006] Therefore, it is urgent to design a traction roll replacement device to solve the above problems. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a traction roll replacement device, which can be quickly locked without manual operation during the lifting process, reduces the difficulty of replacing the traction roll, and ensures the stability of the traction roll replacement device maintained at a preset height.

[0017] As an optional solution, the locking mechanism further includes an unlocking member, which is connected to the frame and is used to apply a force toward the elastic member to the rotating portion to disengage the locking portion from the slot.

[0018] As an optional solution, the unlocking member is pivotally connected to the frame and is located beside the rotating part. The unlocking member includes a connected handle and a pressing part. The handle is protruded from the outside of the frame.

[0019] As an optional solution, the pivot position of the unlocking member is higher than the rotating portion, the pressing portion is arranged in a straight line, and the hand-held portion is inclined downward from the connection position between the hand-held portion and the pressing portion to the free end of the hand-held portion.

[0027] The present utility model provides a traction roller replacement device. When a traction roller needs to be replaced, generally, the supporting member is at the bottom. The lifting member is driven by the driving assembly to rise to a suitable height. During the rising process, the locking portion in the card slot is smoothly disengaged from the card slot and rotates around the pivotal connection position with the frame body and compresses the elastic member, without affecting the normal rising of the lifting member. When the height of the supporting member is appropriate, the driving assembly stops driving. If the lifting member has a tendency to descend, the rotating portion makes the locking portion press into the card slot under the elastic force of the elastic member, and the lifting member cannot descend, thereby locking the height of the lifting member. This process does not require manual operation, and the locking is fast, reducing the difficulty of transferring the traction roller. Description of the Drawings

[0039] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include that the first and second features are not in direct contact but through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.

[0040] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] This embodiment provides a traction roller replacement device that can be quickly locked without manual operation during the lifting process, reducing the difficulty of replacing the traction roller and ensuring the stability of the traction roller replacement device at a preset height. Figure 1 and Figure 2 As shown, the traction roller replacement device includes a frame 10, at least two driving mechanisms 20, a supporting member 30 and a locking mechanism 40. At least two driving mechanisms 20 are arranged at intervals along a first direction (X direction in the figure). The driving mechanism 20 includes a driving component 21 and a lifting component 22. The driving component 21 is installed on the frame 10. The lifting component 22 and the frame 10 slide in a vertical direction (Z direction in the figure, which is perpendicular to the X direction). The driving component 21 can drive the lifting component 22 to move in the vertical direction. A plurality of card slots 2211 are provided on the side wall of the lifting component 22. The plurality of card slots 221 1 are arranged at intervals along the vertical direction; the top of each lifting member 22 is connected to the supporting member 30; the locking mechanism 40 is arranged in a one-to-one correspondence with the driving mechanism 20, and the locking mechanism 40 includes a locking member 41 and an elastic member 42. The locking member 41 is pivotally connected to the frame 10, and the locking member 41 includes a rotating portion 411 and a locking portion 412 arranged at an angle. The free end of the rotating portion 411 is arranged toward the multiple slots 2211, and the two ends of the elastic member 42 respectively abut against the side of the rotating portion 411 away from the locking portion 412 and the frame 10 to drive the rotating portion 411 to abut against any slot 2211.

[0042] The above-mentioned traction roller replacement device, when the traction roller needs to be replaced, generally the supporting member 30 is at the bottom, and the driving component 21 drives the lifting member 22 to an appropriate height. During the rising process, the locking portion 412 in the slot 2211 is disengaged from the slot 2211 and rotates around the pivot position with the frame 10 and compresses the elastic member 42, which does not affect the normal rise of the lifting member 22. When the height of the supporting member 30 is appropriate, the driving component 21 is no longer driven. If the lifting member 22 has a downward trend, the rotating portion 411 is pressed into the slot 2211 by the elastic force of the elastic member 42, and the lifting member 22 cannot descend, thereby locking the height of the lifting member 22. This process does not require manual operation, and the locking is fast, which reduces the difficulty of transferring the traction roller.

[0043] After the height is locked, personnel at the proximal and distal ends of the traction roller respectively sleeve the traction roller and, under unified command, slowly move the traction roller from the distal end to the proximal end. Once the proximal end of the traction roller is out of the annealing furnace, the proximal end personnel place one end of the traction roller on top. After the distal end personnel confirm that the proximal end personnel have placed the traction roller, they continue to push the traction roller toward the proximal end, controlling the direction until the traction roller is completely out of the annealing furnace and at least two supporting members 30 support the traction roller stably. The frame 10 can then be transferred.

[0044] In this embodiment, three driving mechanisms 20, supporting members 30, and locking mechanisms 40 are provided. In other embodiments, the quantity can be flexibly adjusted according to the length of the traction roller.

[0045] As Figure 1 shown, the frame body 10 has four legs 13, and roller wheels 50 are provided at the bottom of each leg 13. At least two of the roller wheels 50 are universal wheels, which can facilitate the transfer of the frame body 10, that is, facilitate the transfer of the traction roller. Optionally, a braking structure is provided on at least one of the roller wheels 50 to facilitate the braking of the frame body 10.

[0046] Optionally, as Figure 1 shown, a handle 60 is connected to one side of the frame body 10, which facilitates the operator to push the frame body 10.

[0047] Optionally, the groove wall of the card slot 2211 spreads from the bottom of the card slot 2211 to the opening, so that during the rising process of the lifting member 22, it is convenient for the locking portion 412 to disengage from the card slot 2211.

[0048] Optionally, as Figure 2 and Figure 3 shown, the locking portion 412 includes a connecting portion 4121 and a protrusion 4122. The connecting portion 4121 is arranged at an angle with the rotating portion 411; the protrusion 4122 protrudes from the free end of the connecting portion 4121 toward the lifting member 22, and the protrusion 4122 can be inserted into any card slot 2211. Through the above settings, the protrusion 4122 can be inserted into the card slot 2211 to achieve locking.

[0049] Optionally, as Figure 3 shown, the lower side of the protrusion 4122 is inclined or arc-shaped, so that during the rising process of the lifting member 22, the protrusion 4122 can smoothly disengage from the card slot 2211.

[0050] It should be noted that when unlocking is required, manually press the rotating portion 411, and the elastic member 42 is compressed, so that the locking portion 412 rotates in a direction away from the card slot 2211, and the protrusion 4122 disengages from the card slot 2211, and the driving assembly 21 drives the lifting member 22 to descend.

[0051] Optionally, as Figure 2 shown, the locking mechanism 40 further includes an unlocking member 43. The unlocking member 43 is connected to the frame body 10 and is used to apply a force to the rotating portion 411 toward the elastic member 42 to disengage the locking portion 412 from the card slot 2211. By operating the unlocking member 43, the locking portion 412 is moved in a direction away from the card slot 2211, and the operation is more convenient, avoiding the operator from reaching into the interior of the frame body 10.

[0052] Optionally, as Figure 2As shown, the unlocking member 43 is pivotally connected to the frame 10 and is located beside the rotating portion 411. The unlocking member 43 includes a connected handle 431 and a pressing portion 432. The handle 431 is protruding from the outside of the frame 10. The free end of the pressing portion 432 can be driven by the handle 431 to press against the side of the rotating portion 411 facing away from the elastic member 42. With this arrangement, the operator lifts the handle 431 from the outside of the frame 10, and the unlocking member 43 rotates around the frame 10, causing the pressing portion 432 to press downward, thereby pressing the rotating portion 411 and the elastic member 42. At the same time, the protrusion 4122 is released from the slot 2211, completing the unlocking process. This makes the operation more convenient and labor-saving for the operator.

[0053] Alternatively, as Figure 2 As shown, the pivot point of the unlocking member 43 is higher than the rotating portion 411, the pressing portion 432 is arranged in a straight line, and the handle portion 431 is tilted downward from its connection with the pressing portion 432 to the free end of the handle portion 431. It is understood that if the unlocking member 43 is an entire straight line, the handle portion 431 will be tilted higher. This arrangement makes the handle portion 431 more horizontal, making the appearance more aesthetically pleasing and providing sufficient operating space when lifted upward.

[0054] Alternatively, as Figure 1 As shown, a rack 221 is provided on the side wall of the lifting member 22. The rack 221 extends vertically and defines a plurality of slots 2211. The drive assembly 21 includes a driving member 211 and a transmission gear 212. The output shaft of the driving member 211 is pivotally connected to the frame 10. The transmission gear 212 is coaxially fixed to the output shaft and meshes with the rack 221. This arrangement makes the rack 221 easier to purchase and, when combined with the lifting member 22, eliminates the need for additional slots 2211 on the lifting member 22, making the manufacturing of the lifting member 22 more convenient.

[0055] Alternatively, as Figure 1 As shown, the driving member 211 comprises a crank handle. Specifically, the operator rotates the crank handle, causing the transmission gear 212 to rotate, driving the lifting member 22 to ascend or descend. As the lifting member 22 ascends, the crank handle stops rotating, and the locking member 41 immediately locks the lifting member 22, preventing the crank handle from reversing when the lifting member 22 descends under the action of gravity. In other embodiments, the driving member 211 may also be a rotary motor. If the rotary motor fails to brake in time, the locking member 41 can still forcibly lock the motor.

[0056] Alternatively, as Figure 1As shown, the frame body 10 includes an upper layer frame 11 and a lower layer frame 12 which are connected and arranged at intervals. The support legs 13 are connected to the lower layer frame 12. The output shaft of the driving member 211 penetrates and is pivotally connected to the upper layer frame 11 along the second direction (the Y direction in the figure, and the Y direction is perpendicular to the X direction and the Z direction respectively). The locking member 41 is pivotally connected to the lower layer frame 12. The two ends of the elastic member 42 respectively abut against the rotating portion 411 and the lower layer frame 12. Through the above arrangement, the driving mechanism 20 and the locking mechanism 40 are reasonably arranged and installed, and the double-layer space of the frame body 10 is cleverly utilized.

[0057] It should be noted that the upper layer frame 11 and the lower layer frame 12 are connected by a plurality of longitudinal beams 14. As Figure 2 shown, the unlocking member 43 is pivotally connected to one of the longitudinal beams 14.

[0058] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
