Description

Technical Field

[0001] The invention relates to the technical field of glass production equipment, and in particular to a sealing box with independent transmission and a roller changing method. Background Art

[0002] With the adjustment of my country's industrial structure, under the requirements of energy conservation, environmental protection and low-carbon economy, the domestic glass production lines under construction and planned to be built are all developing towards high-end float glass. High-end float glass production lines represented by electronic glass, automotive glass, solar photovoltaic glass, etc. have put forward more stringent requirements on the surface quality of glass. The sealing box is located between the outlet end of the tin bath and the first kiln body of the annealing furnace. Its function is to seal the end of the tin bath to prevent external air from entering the tin bath and affecting the atmosphere of the tin bath, and to send the glass plate into the annealing furnace through multiple transition rollers. The transition roller transmission of the existing sealing box is introduced from the main transmission of the annealing furnace through the bridge gear box, and then distributed to multiple transition rollers by the transmission gear box. If the bridge gear box or the transmission gear box fails and needs to be replaced and maintained, the transition roller cannot rotate, and the entire production line will be disconnected, resulting in interruption of glass production operations.

[0003] The glass ribbon is still in a softened state in the sealed box. The temperatures inside the sealed box and the annealing kiln are different. The diameter of the roller will be different after thermal expansion. When rotating, the linear speeds of the front and rear rollers are inconsistent, which will cause tiny scratches under the plate. Such micro scratches have little effect on architectural glass, but will cause downgrading or scrapping of high-end float glass such as electronic glass.

[0004] During production, the tin liquid brought out of the tin bath by the glass is converted into tin ash in the sealing box and adheres to the surface of the transition roller, which will scratch the lower surface of the glass plate and affect the quality of the glass plate. The roller surface needs to be cleaned online in time. If the roller surface defects are serious and cannot be cleaned online, the roller needs to be pulled out and replaced in time. The existing roller changing method is for non-independent transmission sealing boxes, and the shortest roller changing time is about 2 hours.

[0005] Therefore, how to realize the online replacement of the transition roller has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0049] Examples, such as Figure 1-Figure 6As shown, a sealing box with independent transmission includes: a lower box body 107, a roller unit 110, a main transmission station 101, a connecting bracket 116 and an auxiliary transmission station 115.

[0050] The lower box body 107 is horizontally arranged along the transverse direction.

[0053] The connecting bracket 116 is disposed on the operating side of the lower box body 107 , and the connecting bracket 116 is detachably fixedly connected to the lower box body 107 .

[0054] The auxiliary transmission station 115 is installed above the connecting bracket 116 , and the auxiliary transmission station 115 is detachably fixedly connected to the operating end of the roller unit 110 .

[0055] The present invention adopts an independent driving mode, and a plurality of main transmission stations 101 are installed in parallel on the transmission side of the lower box body 107, and an auxiliary transmission station 115 is installed on the operating side of the lower box body 107. The plurality of main transmission stations 101 are connected to the transmission ends of the plurality of roller units 110 in a one-to-one transmission manner, and each roller unit 110 can be driven to rotate independently by the main transmission station 101. When the main transmission station 101 is disconnected from the roller unit 110, the auxiliary transmission station 115 can be quickly connected to the operating end of the roller unit 110 to drive the roller unit 110 to continue to rotate, thereby avoiding the occurrence of a phenomenon in which the plurality of roller units 110 stop rotating due to a failure of the bridge gear box or the transmission gear box.

[0056] Specific embodiment 1, as Figure 1-Figure 6 As shown, a sealing box with independent transmission includes: a lower box body 107, a roller unit 110, a main transmission station 101, a connecting bracket 116 and an auxiliary transmission station 115.

[0057] The lower box body 107 is horizontally arranged along the transverse direction.

[0058] Preferably, Figure 1 and Figure 2 As shown, a glass bin 108 is formed on the lower box body 107, and the glass bin 108 is located directly below the roller unit 110, and the top opening of the glass bin 108 is located directly below the two roller units 110; a bin door 109 connected to the glass bin 108 is provided on one side of the lower box body 107 for cleaning materials falling into the glass bin 108.

[0059] The number of the roller units 110 is three. The three roller units 110 are arranged in parallel in the longitudinal direction, and the roller units 110 are fixedly installed directly above the lower box body 107 .

[0060] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the roller unit 110 includes a transition roller 111, a roller base 112, a shaft end sealing structure 113 and a support bearing seat 114; the roller base 112 is arranged in parallel in the transverse direction just above the lower box body 107, and the roller base 112 is fixedly connected to the lower box body 107; the number of the support bearing seats 114 is two, and the two support bearing seats 114 are fixedly connected to the two ends of the roller base 112 in a one-to-one correspondence, that is, one support bearing seat 114 is fixedly connected to the left end of the roller base 112, and the other support bearing seat 114 is fixedly connected to the right end of the roller base 112; the number of the shaft end sealing structures 113 is two, the two shaft end sealing structures 113 are arranged between the two support bearing seats 114, and the shaft end sealing structure 113 is fixedly connected to the roller base 112, so as to block the gas exchange and heat exchange inside and outside the sealing box. The transition roller 111 is arranged in parallel above the roller base 112 in the transverse direction, and both ends of the transition roller 111 axially extend through the shaft end sealing structure 113 and are fixedly connected to the supporting bearing seat 114 .

[0061] At the transmission end of the transition roller 111 , the shaft neck and the retaining ring 105 are respectively pressed against the two sides of the supporting bearing seat 114 to limit the expansion of the transition roller 111 in the transmission side direction of the lower box body 107 , so that the transition roller 111 can only expand toward the operating side of the lower box body 107 .

[0062] The water cooling jacket 106 is installed between the side of the lower box body 107 and the support bearing seat 114. Softened water is introduced into the interior of the water cooling jacket 106. Multiple water cooling jackets 106 are arranged at both ends of the lower box body 107. The water inlet interface and the water outlet interface can be connected in series or can be independently fed in and out of water. The function of the water cooling jacket 106 is to block the heat radiated from both sides of the lower box body 107 to the support bearing seat 114, so as to prevent the support bearing seat 114 from being damaged or having its service life shortened due to high temperature.

[0063] It should be noted that the shaft end sealing structure 113 and the supporting bearing seat 114 are both existing technologies and will not be described in detail here.

[0064] Preferably, the fixed connection between the lower box 107 and the roller unit 110 is achieved as follows: three transverse through grooves (not shown in the figure) are formed on the top of the lower box 107, and the transverse through grooves penetrate the lower box 107 in the transverse direction; each roller unit 110 includes a transition roller 111 and a roller base 112, and the transition roller 111 is installed on the roller base 112 through the support bearing seats 114 at both ends, and the roller base 112 is installed on the upper surface of the lower box 107, and a key groove is provided at the bottom of each roller base 112, and the key groove corresponds to the position of the transverse through groove at the top of the lower box 107. When the roller base 112 is adjusted to the right position on the lower box 107, a key (not shown in the figure) is inserted into the key groove and the transverse through groove to provide a limit for the roller unit 110 in the advancing direction of the glass plate, so as to ensure the parallelism of the multiple transition rollers 111.

[0065] The number of the main transmission stations 101 is three, and the main transmission stations 101 are fixedly installed on the transmission side of the lower box 107, that is, the lower box 107 is located on the transmission side of the annealing kiln roller, and the main transmission stations 101 are fixed on the ground on the transmission side of the annealing kiln roller through support legs. The three main transmission stations 101 are connected to the transmission ends of the three roller units 110 in a one-to-one corresponding manner.

[0066] Specifically, Figure 2 and Figure 5 As shown, a main transmission mechanism is connected between the main transmission station 101 and the transition roller 111, and the main transmission mechanism includes an overrunning clutch 104, a coupling 102 and a protective cover 103. The overrunning clutch 104 is fixedly connected to the transmission end of the transition roller 111, and the coupling 102 is connected between the overrunning clutch 104 and the main transmission station 101. The protective cover 103 is arranged on the outside of the coupling 102 to protect the personal safety of the operator.

[0067] The connecting bracket 116 is installed on the operating side of the lower box body 107 , and the connecting bracket 116 is detachably fixedly connected to the lower box body 107 . The auxiliary transmission station 115 is fixedly installed above the connecting bracket 116 .

[0068] Specifically, Figure 6As shown, the connecting bracket 116 includes a plug-in plate 124 and a rotating hook 123. The plug-in plate 124 is arranged in the horizontal direction. A horizontal plug-in slot 127 matching the plug-in plate 124 is provided at the end of the roller base 112. The number of the rotating hooks 123 is two, and the rotating hooks 123 are relatively rotatably installed above one end of the plug-in plate 124. When one end of the plug-in plate 124 is transversely inserted into the horizontal plug-in slot 127, the rotating hook 123 is rotated so that the rotating hook 123 is hooked on the screw head 122 on the side of the roller unit 110, and then the jacking bolt 121 at the end of the plug-in plate 124 is screwed. Through the lifting and lowering of the jacking bolt 121 and the contact with the roller base 112, the connecting bracket 116 is lifted upward, so that the plug-in plate 124 of the connecting bracket 116 is in close contact with the roller base 112, and finally the connecting bracket 116 and the lower box body 107 are fixedly connected by bolts.

[0069] A sliding support 125 is fixedly installed above the other end of the plug board 124, and the sliding support 125 can move along the axial direction of the transition roller 111; a lifting support 126 is fixedly installed on the sliding support 125, and the vertical height of the lifting support 126 can be adjusted, and the auxiliary transmission station 115 is fixedly installed on the lifting support 126.

[0070] Specifically, a long hole is opened in the horizontal direction on the sliding support 125, and when the transition roller 111 expands, the sliding support 125 can be moved away from the roller unit 110; the lifting support 126 is installed on the vertical plate of the sliding support 125, and a long hole is opened in the vertical direction on the lifting support 126 to adjust the center line height of the power output shaft of the auxiliary transmission station 115.

[0071] The auxiliary transmission station 115 is detachably fixedly connected to the operating end of the roller unit 110 .

[0072] Specifically, Figure 4 and Figure 5As shown, an auxiliary transmission mechanism is connected between the auxiliary transmission station 115 and the transition roller 111, and the auxiliary transmission mechanism includes an overrunning clutch 104, a roller end flange 120, a connecting rod 119, a connecting plate 117 and a connecting pipe 118; the connecting pipe 118 is coaxial with the power output shaft of the auxiliary transmission station 115, and one end of the connecting pipe 118 is fixedly installed on the power output shaft of the auxiliary transmission station 115, and two steel connecting plates 117 are fixedly connected to the end of the connecting pipe 118 away from the auxiliary transmission station 115, and the connecting plate 117 is arranged along the radial direction of the connecting pipe 118, and one end of the connecting plate 117 is fixedly connected to the connecting pipe 118, and the other end of the connecting plate 117 is located between the two connecting rods 119 arranged in parallel, that is, the other end of the connecting plate 117 is inserted between the two connecting rods 119 arranged in parallel. The connecting rod 119 is arranged parallel to the transition roller 111 but not coaxially, and one end of the connecting rod 119 is vertically fixedly connected to the roller end flange 120, and the roller end flange 120 is fixedly connected to the operating end of the transition roller 111 through the overrunning clutch 104. When installing the auxiliary transmission station 115, it is only necessary to insert the connecting plate 117 at the front end of the connecting pipe 118 between the two connecting rods 119 connected to the roller end flange 120, which can ensure that the auxiliary transmission station 115 is quickly connected when a problem occurs and adapt to the height change of the transition roller 111.

[0073] It should be noted that: under normal production conditions, the auxiliary transmission station 115 can be dismantled and stored in a warehouse; the auxiliary transmission station 115 is connected to the transition roller 111 only when the main transmission station 101 needs maintenance, servicing, failure or roller replacement.

[0074] Specific embodiment 2, as Figure 7 and Figure 8 As shown, a roller changing method is used to perform online roller changing operation on the above-mentioned sealing box with independent transmission; the roller changing method comprises the following steps:

[0075] Before carrying out the specific roll changing operation, the following process preparations need to be made to ensure that the roll changing operation can be carried out quickly and safely:

[0076] 1. The new roller unit is placed near the sealing box for use.

[0077] 2. Adjust the thickness of the glass plate (the thickness of the glass plate after adjustment is about 6 to 8 mm) and make the width of the glass plate as narrow as possible (this item is optional and the manufacturer will determine whether to use it based on actual production conditions and operating habits).

[0078] 3. Prepare operating tools, including adjustable wrench, ratchet wrench, forklift and lifting tools, etc.

[0079] 4. Check whether the auxiliary transmission station, the roll transmission station of the roll changing vehicle and the electric control cabinet are functioning normally.

[0080] 5. Lower the height of the graphite block of the tin-wiping device of the roller unit to be replaced to the lowest point and pull out the tin-wiping device.

[0081] 6. After recording the roller surface elevation of each transition roller, lower the roller surface height of the transition roller to be replaced, and adjust the roller surface elevation of the remaining transition rollers upward.

[0082] Step 1: Release the fixed connection between the roller base 112 and the lower box 107, and fix one lateral end of the roller changing vehicle 128 to the operating side of the lower box 107

[0083] Specifically, the fixing bolts and positioning keys between the roller base 112 and the lower box body 107 of the roller unit 110 (also called the old roller unit) that needs to be replaced are removed.

[0084] First, install the hook 138 on the operating side of the lower box 107; then push the roll-changing cart 128 to move to the operating side of the lower box 107, so that the center line of the roll-changing cart 128 is aligned with the center line of the horizontal through groove of the lower box 107 directly below the roll-changing unit 110 that needs to be replaced; finally, lift the supporting foot 136 to align the upper surface of the body 129 of the roll-changing cart 128 with the bottom surface of the horizontal through groove of the lower box 107, and the connecting pin 133 at the end of the body 129 is stuck on the hook 138 to prevent the body 129 from moving during the roll changing process.

[0085] Step 2: The disc roller transmission station 130 on the roller changing vehicle 128 is connected to the operating end of the transition roller 111 by transmission.

[0086] Specifically, Figure 5 , Figure 7 and Figure 8 As shown, a roller end flange 120 is installed at the end of the transition roller 111, and a connecting pipe 118 is installed on the power output shaft of the disc roller transmission station 130; the power output shaft of the disc roller transmission station 130 and the axis of the transition roller 111 are aligned by adjusting the height of the lifting support 126 on the vehicle-mounted lifting bracket 131; the vehicle-mounted lifting bracket 131 is moved, and the plug-in plate 124 of the vehicle-mounted lifting bracket 131 is inserted into the horizontal plug-in groove 127 at one end of the roller base 112. After it is in place, the jacking bolt 121 on the plug-in plate 124 is rotated to make the jacking bolt 121 press against the bottom plate of the roller base 112, and the rotating hook 123 is rotated to make the rotating hook 123 hook the screw head 122 on the side of the roller unit 110; the disc roller transmission station 130 is started to drive the transition roller 111 to rotate.

[0087] Step three: release the transmission connection between the main transmission station 101 and the transition roller 111 , and install the auxiliary lifting bracket 139 on the transmission side of the lower box body 107 .

[0088] Specifically, first remove the protective cover 103 and the coupling 102 between the main transmission station 101 and the transition roller 111 that needs to be replaced in sequence; then install the auxiliary lifting bracket 139 on the transmission side of the lower box 107, and align the upper surface of the auxiliary lifting bracket 139 with the bottom surface of the transverse through groove of the lower box 107; then insert the plug-in plate 124 of the auxiliary lifting bracket 139 into the horizontal plug-in groove 127 on the transmission side of the roller base 112. After it is in place, rotate the jacking bolt 121 on the plug-in plate 124 to make the jacking bolt 121 press against the bottom plate of the roller base 112, and rotate the rotating hook 123 to make the rotating hook 123 hook the screw head 122 on the side of the roller unit 110.

[0089] Step 4: The roller unit 110 is driven to move laterally by the roller changing vehicle 128 .

[0090] Specifically: operate the lift 132 installed on the vehicle-mounted lifting bracket 131 and the auxiliary lifting bracket 139 to lift the vehicle-mounted lifting bracket 131 and the auxiliary lifting bracket 139 upwards, so that the roller unit 110 is completely separated from the lower box body 107; operate the hand wheel on the roller changing vehicle 128 to drive the roller unit 110 to move horizontally through the chain drive assembly 135, so as to drag the transition roller 111 out of the lower box body 107.

[0096] 3. Arrange the installation tools, and store the roller changing cart, auxiliary transmission station, etc. properly for next use.

[0097] 4. Check the usage of the removed roller unit wearing parts. If the quality does not meet the standards, they must be replaced. The old rollers must be cleaned of surface defects and can be used again only after the surface quality meets the standards.

[0098] It should be noted that the roller changing vehicle 128 includes a vehicle body 129, a vehicle-mounted lifting bracket 131, a disc roller transmission station 130, a supporting foot 136, a moving wheel 137, a lift 132 and a chain transmission assembly 135; the vehicle body 129 is rectangular in shape as a whole, and supporting feet 136 and moving wheels 137 are fixedly installed at both ends and the lower middle part of the vehicle body 129; the vehicle-mounted lifting bracket 131 is arranged above one end of the vehicle body 129, and the vehicle-mounted lifting bracket 131 includes a plug-in plate 124 and a rotating hook 123; the lift 132 is installed on the vehicle-mounted lifting bracket 131, and the bottom end of the lift 132 passes through the plug-in plate 124 and is equipped with wheels, so that the vehicle-mounted lifting bracket 131 and the vehicle body 129 can move relative to each other. There are two groups of chain transmission assemblies 135, which are installed one by one on both sides of the vehicle body 129, and the two sides of the plug-in plate 124 are fixedly connected by a limiting connecting plate 134, so as to drive the vehicle-mounted lifting bracket 131 to move back and forth horizontally through the chain transmission assembly 135.

[0099] A connecting pin 133 is fixedly connected to one end of the vehicle body 129 for being fixedly connected to the lower box body 107, and the disc-roller transmission station 130 is fixedly connected to the other end of the plug-in board 124, and the connection method between the disc-roller transmission station 130 and the plug-in board 124 is the same as the connection method between the auxiliary transmission station 115 and the plug-in board 124; a handwheel for driving the chain transmission assembly 135 is fixedly connected to the other end of the vehicle body 129.

[0100] Specific embodiment 3, as Figure 6 , Figure 7 and Fig. 9 As shown, a roller changing method is used to perform online roller changing operation on the above-mentioned sealing box with independent transmission; the roller changing method comprises the following steps:

[0101] Step 1: Release the fixed connection between the roller base 112 and the lower box body 107 , and fix one lateral end of the roller changing vehicle 128 to the operating side of the lower box body 107 .

[0102] Specifically, the fixing bolts and positioning keys between the roller base 112 of the roller unit 110 that needs to be replaced and the lower box 107 are removed; the hook 138 is first installed on the operating side of the lower box 107; then the roller changing cart 128 is pushed to the exit side of the roller unit 110 to align the center line of the roller changing cart 128 with the center line of the horizontal through groove of the lower box 107 directly below the roller changing unit 110 that needs to be replaced; finally, the supporting foot 136 is lifted to align the upper surface of the body 129 of the roller changing cart 128 with the bottom surface of the horizontal through groove of the lower box 107, and the connecting pin 133 is stuck on the hook 138 to prevent the body 129 from moving during the roller changing process.

[0103] Step 2: The disc roller transmission station 130 on the roller changing vehicle 128 is connected to the operating end of the transition roller 111 by transmission.

[0104] Specifically, a roller end flange 120 is installed at the axial end of the transition roller 111, and a connecting pipe 118 is installed on the power output shaft of the disc roller transmission station 130; the power output shaft of the disc roller transmission station 130 and the axis of the transition roller 111 are aligned by adjusting the height of the vehicle-mounted lifting bracket 131; the vehicle-mounted lifting bracket 131 is moved and the plug-in plate 124 of the vehicle-mounted lifting bracket 131 is inserted into the horizontal plug-in groove 127 at one end of the roller base 112. After it is in place, the jacking bolt 121 on the plug-in plate 124 is rotated to make the jacking bolt 121 press against the bottom plate of the roller base 112, and the rotating hook 123 is rotated to make the rotating hook 123 hook the screw head 122 on the side of the roller unit 110; the disc roller transmission station 130 is started to drive the transition roller 111 to rotate.

[0105] Step three: release the transmission connection between the main transmission station 101 and the transition roller 111 , and fix another roll-changing vehicle 128 with the new roller unit 110 mounted thereon to the transmission side of the lower box 107 .

[0106] Specifically, first remove the protective cover 103 and the coupling 102 between the main transmission station 101 and the transition roller 111 that needs to be replaced in sequence; push the other roll-changing vehicle 128 to move to the transmission side of the lower box 107, lift the supporting foot 136 of the roll-changing vehicle 128, and align the center line of the vehicle body 129 of the roll-changing vehicle 128 with the center line of the horizontal through groove of the lower box 107 directly below the roller unit 110 that needs to be replaced; the connecting pin 133 is stuck on the hook 138 to prevent the vehicle body 129 from moving during the roll-changing process.

[0107] It should be noted that the lifting brackets 131 on the two roll-changing vehicles 128 are oriented in opposite directions.

[0108] Step 4: The new roller unit 110 on the roller changing vehicle 128 is axially fixedly connected to the old roller unit 110 .

[0109] Specifically, the new roller unit 110 is hoisted onto the roller changing vehicle 128, and the roller lifting bracket 141 is fixedly connected to the roller bases of the two roller units, that is, the right end of the plug-in plate 124 of the roller lifting bracket 141 is inserted into the horizontal plug-in slot 127 of the old roller unit 110, and the left end of the roller lifting bracket 141 is inserted into the horizontal plug-in slot 127 of the new roller unit 110. After it is in place, the jacking bolts 121 at both ends of the plug-in plate 124 are rotated to make the jacking bolts 121 press against the bottom plates of the two roller bases 112, and the rotating hook 123 is rotated to make the rotating hook 123 hang on the screw head 122 on the sides of the two roller units 110.

[0110] Insert the right end of the plug-in plate of the vehicle-mounted lifting bracket 131 on the other end of the roller changing vehicle 128 into the horizontal plug-in slot 127 of the new roller unit 110. After it is in place, rotate the jacking bolts 121 at both ends of the plug-in plate 124 to make the jacking bolts 121 press against the bottom plates of the two roller bases 112, and rotate the rotating hook 123 to make the rotating hook 123 hook the screw head 122 on the sides of the two roller units 110.

[0111] Step 5: The roller unit 110 is driven to move laterally by the roller changing vehicle 128 .

[0112] Specifically, the lift 132 installed on the vehicle-mounted lifting bracket 131 and the roller-connected lifting bracket 141 is operated to lift the vehicle-mounted lifting bracket 131 and the roller-connected lifting bracket 141 upward, so that the new roller unit 110 is completely separated from the roller-changing vehicle 128, and the old roller unit 110 is completely separated from the lower box 107.

[0113] The hand wheel on the roller changing vehicle 128 is operated to drive the two roller units 110 to move synchronously laterally through the chain drive assembly 135 , thereby dragging the old roller unit 110 out of the lower box 107 and bringing the new roller unit 110 into the lower box 107 .

[0114] The working principle of the sealing box of the present invention is as follows:

[0115] Each transition roller 111 of the sealing box is driven by the main transmission station 101. When the main transmission of the transition roller 111 fails, the auxiliary transmission station 115 can quickly access the transmission of the transition roller 111. Overrunning clutches 104 are installed on both sides of the transition roller 111 to effectively protect the personal safety of the operator. The bottom of the lower box 107 is provided with a glass bin 108, and broken glass and tin ash will fall into the glass bin 108, which will not cause broken glass to accumulate inside the lower box 107, and can be cleaned by opening the bin door 109 in the tin tank pit.

[0116] The two roller changing methods in the present invention can perform roller changing operations from the transmission side and the non-transmission side. In these two roller changing methods, the time for the transition roller 111 to pass through the lower box body 107 is less than 1 minute, and when changing the roller, the roller unit 110 is guided when entering and exiting the lower box body 107, and will not deviate. While shortening the roller changing time, it also ensures the safety of the roller changing operation. The corresponding roller changing method can be selected according to the on-site conditions and one's own requirements.

[0117] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
