Description

Technical Field

[0001] This utility model relates to the field of liquid crystal glass forming technology, and specifically to a glass traction roller, which is a traction roller crank arm disassembly device. Background Technology

[0002] Overflow pull-down is an advanced non-contact ultra-thin glass forming technology, mainly used for producing high-precision liquid crystal display substrate glass and ultra-thin flexible glass, and has now become the mainstream production process in the display industry. The core process of overflow pull-down consists of four stages: First, molten glass distribution: after the borosilicate glass raw material is melted in a pure oxygen combustion environment at 1600℃, it flows into a V-shaped overflow channel through a platinum channel; Second, double-sided overflow forming: the melt flows naturally down along both sides of the overflow channel, converging at the bottom of the wedge to form a complete glass strip, only in contact with air throughout the process, avoiding surface damage; Third, precision thickness control: through the synergistic action of the traction roller linear speed and the edge-pulling machine rollers, the thickness can be adjusted from 0.03-0.7mm, while short roller technology is used to eliminate the thermal shrinkage deformation of the glass; Fourth, annealing and strengthening treatment: after the glass strip is stress-relieved in the 550℃ annealing zone, it is chemically tempered to increase the surface hardness to above 7H.

[0003] As a crucial component of glass forming equipment, the glass traction roller has a limited service life and requires periodic disassembly and replacement. Crank arms, installed at both ends of the traction roller to support it, are prone to seizing with the roller's bearings under prolonged high-temperature operation, making disassembly difficult and sometimes requiring damage, which is time-consuming and labor-intensive. To address these technical problems, we propose a traction roller crank arm disassembly device. Utility Model Content

[0004] The purpose of this invention is to provide a traction roller crank arm disassembly device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a traction roller crank arm disassembly device is provided, comprising a disassembly device body, a crank arm installed on one side of the disassembly device body, a bushing provided on the disassembly device body, the bushing being sleeved on the crank arm main shaft, a front top plate fixedly connected to the end of the bushing, an outer guide sleeve fixedly provided at the bottom of the front top plate, and a rear top plate installed on the side of the front top plate away from the bushing, a crossbeam fixedly connected to the back of the rear top plate, pull rods inserted on both sides of the crossbeam, and a pull-out component welded and fixed to the end of the pull rod, the pull-out component being snapped onto the side wall of the crank arm.

[0006] Furthermore, the rear top plate is U-shaped, and an inner guide sleeve is welded to the bottom of the rear top plate. The inner guide sleeve is rectangular and is arranged opposite to the outer guide sleeve. The inner guide sleeve is inserted inside the outer guide sleeve. The length of the outer guide sleeve is 40mm, and the length of the inner guide sleeve is 150mm. The length of the rear top plate is 100mm, and the length of the bushing is 90mm.

[0007] Furthermore, the crossbeam is rectangular, and there are waist holes on both sides of the crossbeam. Tie rods are inserted into the two sets of waist holes, and the length of the crossbeam is 220mm.

[0008] Furthermore, a locking nut is screwed onto the end of the pull rod, and a limiting sleeve is provided on one side of the locking nut, which is sleeved on the outer ring surface of the pull rod.

[0010] Furthermore, the front top plate is square, with a length of 100mm, and the front top plate and the rear top plate surround each other to form a space for accommodating the hydraulic cylinder.

[0011] Compared with the prior art, the advantages of this utility model are: the length of the adjustable pull rod can be fixed firmly by using a C-shaped pull-out part to snap onto both sides of the back of the crank arm, thus preventing the parts from shaking during disassembly; by using a hydraulic jack cylinder to work within the hydraulic jack cylinder's accommodating space, the crank arm can be moved slowly until it is disengaged from the bearing by extending the output end to push the rear top plate, thus achieving quick disassembly and saving a lot of time; and the whole process will not damage the crank arm, effectively protecting the integrity of the crank arm.

[0020] Please see Figure 1-6 This utility model provides a traction roller crank arm disassembly device, including a disassembly device body 100, a crank arm 200 installed on one side of the disassembly device body 100, a bushing 1 provided on the disassembly device body 100, the bushing 1 being sleeved on the main shaft of the crank arm 200, a front top plate 2 fixedly connected to the end of the bushing 1, an outer guide sleeve 3 fixedly provided at the bottom of the front top plate 2, and a rear top plate 5 installed on the side of the front top plate 2 away from the bushing 1, a crossbeam rod 6 fixedly connected to the back of the rear top plate 5, and a pull rod 7 inserted on both sides of the crossbeam rod 6, with a pull member 73 welded and fixed to the end of the pull rod 7, and the pull member 73 being snapped onto the side wall of the crank arm 200.

[0021] Working principle: In actual use, first hold the front top plate 2 and put the bushing 1 on it onto the main shaft of the crank arm 200. At the same time, hold the rear top plate 5 and insert the inner guide sleeve 4 at its bottom into the inner guide sleeve 3. Simultaneously adjust the length of the pull rod 7 and use the C-shaped pull-out parts 73 at the ends of the two sets of pull rods 7 to lock onto the back sides of the crank arm 200. Then, place the hydraulic cylinder inside the hydraulic cylinder receiving space 50. The output end of the hydraulic cylinder abuts against the inner wall of the rear top plate 5. Start the switch of the hydraulic cylinder. The output end begins to extend, pushing the rear top plate 5 backward. With the support of the two sets of pull-out parts 73, the crank arm 200 slowly moves outward until the crank arm 200 is disengaged from the bearing. This achieves the purpose of quickly disassembling the crank arm 200 and the bearing on the first roller, saving time and effort. During the disassembly process, the crank arm 200 will not be damaged.

[0022] In a preferred embodiment, the rear top plate 5 is U-shaped, and an inner guide sleeve 4 is welded to the bottom of the rear top plate 5. The inner guide sleeve 4 is rectangular and is arranged opposite to the outer guide sleeve 3. The inner guide sleeve 4 is inserted inside the outer guide sleeve 3. The length of the outer guide sleeve 3 is 40mm, and the length of the inner guide sleeve 4 is 150mm. The length of the rear top plate 5 is 100mm, and the length of the bushing 1 is 90mm.

[0023] The crossbeam 6 is rectangular, and there are waist holes 61 on both sides of the crossbeam 6. A tie rod 7 is inserted inside the two sets of waist holes 61. The length of the crossbeam 6 is 220mm.

[0024] A locking nut 71 is screwed to the end of the pull rod 7, and a limiting sleeve 72 is provided on one side of the locking nut 71. The limiting sleeve 72 is sleeved on the outer ring surface of the pull rod 7.

[0025] The pull-out part 73 is C-shaped, and the length of the pull rod 7 is 320mm.

[0026] In a preferred embodiment, the front top plate 2 is square and has a length of 100mm. The front top plate 2 and the rear top plate 5 surround each other to form a hydraulic cylinder receiving space 50.

[0027] like Figure 1-6 As shown, when this utility model is in operation, the front top plate 2 is held and the bushing 1 is fitted onto the main shaft. The inner guide sleeve 4 of the rear top plate 5 is inserted into the outer guide sleeve 3, which can accurately position the components and ensure stability during disassembly. The length of the pull rod 7 is adjusted, and the C-shaped pull-out piece 73 is used to snap onto both sides of the back of the crank arm 200, which can firmly fix the components and prevent them from shaking during disassembly. With the help of the hydraulic cylinder, the crank arm 200 can be moved slowly until it is disengaged from the bearing by extending the output end and pushing the rear top plate 5. This achieves quick disassembly and saves a lot of time. Moreover, the whole process will not damage the crank arm 200 and effectively protects the integrity of the crank arm 200.

[0028] The above description is merely an example and illustration of the structure of this utility model.
