The flow of molten glass is specifically regulated by adjusting the distance between the runner gate and the bottom surface of the runner.

[0003] In actual production, the gate will be worn out due to long-term erosion by the glass liquid.

For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0049] In order to illustrate the technical solution of the present invention, the following is a description with reference to specific drawings and embodiments.

[0050] An embodiment of the present application provides a gate adjustment device, which uses a lifting rod assembly to adjust the distance between the gate and the bottom surface of the flow channel. At the same time, when the lifting rod assembly reaches the lowering limit position, an adjustment bracket is used to temporarily support the hanging beam and adjust the relative position between the lifting rod assembly and the hanging beam, so that the lifting rod assembly can continue to drive the hanging beam to descend.

[0051] refer to Figures 1 to 3 The gate plate adjustment device provided in this embodiment includes a suspension beam 1, a lifting rod assembly 2 and an adjustment bracket 3.

[0052] A gate plate 5 is provided on the side of the hanging beam 1 facing the flow channel 4. The hanging beam 1 is used to provide a fixed foundation for the gate plate 5. A sling 11 is provided on the hanging beam 1. The sling 11 is located on the side of the hanging beam 1 facing the flow channel 4. The hanging beam 1 drives the gate plate 5 to rise and fall synchronously through the sling 11. The hanging beam 1 is located above the flow channel 4.

[0053] One end of the lifting rod assembly 2 is placed on a fixed foundation, which can be the ground, a workbench or other similar fixed foundations. The hanging beam 1 is detachably connected to the other end of the lifting rod assembly 2. The lifting and lowering of the lifting rod assembly 2 can drive the hanging beam 1 to rise and fall synchronously.

[0054] Because the gate plate 5 is usually higher and the suspension beam 1 is usually located at a higher position, the lifting rod assembly 2 is a variety of commonly used retractable devices that cooperate with the rod 25 to provide support for the suspension beam 1. The retractable device can be an electric retractable cylinder, a pneumatic cylinder, a hydraulic cylinder or other similar retractable devices.

[0055] The adjusting bracket 3 is used to temporarily support the hanging beam 1 when the lifting rod assembly 2 descends to the extreme position. One end of the adjusting bracket 3 is placed on a fixed foundation, which can be the ground, a workbench, the side wall of the flow channel 4 or other similar fixed foundations. The adjusting bracket 3 and the other end are against the hanging beam 1.

[0056] Because the lifting rod assembly 2 has an extreme lifting position due to structural limitations, when the lifting rod assembly 2 drives the suspension beam 1 to descend to the extreme position, the lifting rod assembly 2 cannot continue to descend, and as the glass liquid is eroded and corroded, the gate plate 5 will continue to wear and become shorter, and the flow rate of the glass liquid cannot be further controlled at this time; therefore, when the lifting rod assembly 2 drives the suspension beam 1 to descend to the extreme position, the adjustment bracket 3 is used to temporarily support the suspension beam 1, and the suspension beam 1 is removed from the lifting rod assembly 2, and then the lifting rod assembly 2 is controlled to rise and the suspension beam 1 is reinstalled on the lifting rod assembly 2. At this time, the distance between the suspension beam 1 and the top of the lifting rod assembly 2 becomes larger, and the lifting rod assembly 2 can drive the suspension beam 1 to further descend.

[0057] The adjusting bracket 3 is a retractable bracket. The adjusting bracket 3 can be firstly in a retracted state so that it can be placed between the hanging beam 1 and the fixed foundation. Then, the adjusting bracket 3 can be controlled to extend and abut against the hanging beam 1 to provide support for the hanging beam 1.

[0058] The adjusting bracket 3 can be any type of retractable device, such as an electric retractable cylinder, a pneumatic cylinder, a hydraulic cylinder or other similar retractable devices.

[0059] The operation process and principle of this embodiment are as follows: in the initial state, the suspension beam 1 is located at the end of the lifting rod assembly 2. As the gate plate 5 is worn and corroded, the lifting rod assembly 2 drives the suspension beam 1 to gradually drop as it is worn and maintains the distance between the gate plate 5 and the bottom surface of the flow channel 4. When the lifting rod assembly 2 drops to the limit position, the lifting rod assembly 2 cannot continue to drop; the adjustment bracket 3 is put into a retracted state and placed between the suspension beam 1 and the fixed foundation of the adjustment bracket 3, the adjustment bracket 3 is controlled to extend and abut against the suspension beam 1, at this time, the adjustment bracket 3 can support the suspension beam 1 and keep the suspension beam 1 stable; the suspension beam 1 is removed from the lifting rod assembly 2, the lifting rod assembly 2 is controlled to extend to the limit position, and then the suspension beam 1 is installed on one side of the lifting rod assembly 2. At this time, the lifting rod assembly 2 can continue to drop and drive the suspension beam 1 to drop, and the relative position adjustment between the suspension beam 1 and the lifting rod assembly 2 is completed, and then the adjustment bracket 3 is controlled to retract and be taken out.

[0060] The beneficial effects of this embodiment are as follows: the lifting beam 1 is supported by the liftable lifting rod assembly 2, and the height of the lifting beam 1 can be adjusted according to the wear of the gate plate 5, thereby improving the utilization rate of the gate plate 5; an adjustment bracket 3 for temporary support is provided, which temporarily supports the lifting beam 1 when the lifting rod assembly 2 reaches the lowering limit position, so as to facilitate the adjustment of the relative position of the lifting beam 1 and the lifting rod assembly 2, thereby expanding the lifting range of the lifting rod assembly 2 without stopping the machine, thereby further improving the utilization rate of the gate plate 5.

[0061] refer to Figure 4 , Figure 5 In one embodiment, the adjusting bracket 3 includes a bracket body 31 , a top rod 32 and a telescopic rod 33 .

[0062] The support body 31 is placed on the ground, a workbench, a side wall of the flow channel 4 or other fixed foundations, and the support body 31 is used to provide a fixed foundation for the top rod 32 and the telescopic rod 33.

[0063] The top rod 32 is slidably connected to the bracket body 31, and the top rod 32 can slide toward the bracket body 31 or away from the bracket body 31. When the adjustment bracket 3 is placed under the suspension beam 1, the top rod 32 slides toward the direction away from the bracket body 31, that is, gradually approaches the suspension beam 1, and the top rod 32 can be supported by the suspension beam 1.

[0064] The sliding connection method of the push rod 32 can be: fix the guide cylinder 36 on the bracket body 31, and fix the guide rod 35 on the push rod 32, so that the guide rod 35 is slidably connected in the guide cylinder 36, thereby realizing the sliding connection between the push rod 32 and the bracket body 31.

[0065] It can be understood that the above structure is only one embodiment of the sliding connection between the top rod 32 and the bracket body 31, and the sliding connection between the top rod 32 and the bracket body 31 can also be other sliding connection structures.

[0066] One end of the telescopic rod 33 is disposed on the bracket body 31 and the other end is connected to the top rod 32 . The telescopic rod 33 can drive the top rod 32 to move relative to the bracket body 31 .

[0067] The telescopic rod 33 is any commonly used telescopic device, such as an electric telescopic cylinder, a pneumatic cylinder, a hydraulic cylinder or other similar telescopic devices.

[0068] Optionally, the telescopic rod 33 is a screw rod, one end of the telescopic rod 33 is rotatably connected to the bracket body 31 and the other end is threadedly engaged with the top rod 32. The threaded engagement of the telescopic rod 33 and the top rod 32 can be specifically that a second threaded hole is opened on the top rod 32, one end of the telescopic rod 33 is placed in the second threaded hole and threadedly engaged with the second threaded hole. Since the top rod 32 and the bracket body 31 are slidingly connected and cannot rotate, the rotation of the telescopic rod 33 can drive the top rod 32 to move along the telescopic rod 33 toward or away from the bracket body 31.

[0069] Furthermore, the top rod 32 is fixedly connected to the second threaded sleeve 321, and the telescopic rod 33 and the second threaded sleeve 321 are threadedly matched. Compared with the second threaded hole, the matching length between the telescopic rod 33 and the second threaded sleeve 321 is longer, which can ensure that the structure is more stable and smooth. At the same time, when not in use, the telescopic rod 33 can also be accommodated in the second threaded sleeve 321, thereby protecting the telescopic rod 33.

[0070] The beneficial effects of this embodiment are: the use of a screw and a threaded sleeve to control the extension and retraction of the push rod 32 relative to the bracket body 31 can achieve stepless control of the extension and retraction of the push rod 32; the displacement of the push rod 32 driven by each rotation of the screw is small, which is convenient for fine control of the feed of the push rod 32; and the cost is low.

[0071] Optionally, the telescopic rod 33 is a double-headed screw, and the two ends of the telescopic rod 33 are respectively threadedly engaged with the bracket body 31 and the top rod 32. The specific method of the threaded engagement can be that a first threaded hole is opened on the bracket body 31, and a second threaded hole is opened on the top rod 32. The two ends of the telescopic rod 33 are respectively threadedly engaged with the first threaded hole and the second threaded hole. Because the bracket body 31 is fixed, the top rod 32 and the bracket body 31 are slidingly connected and cannot rotate. Therefore, rotating the telescopic rod 33 can drive the top rod 32 to move along the telescopic rod 33 in the direction of approaching the bracket body 31 or away from the bracket body 31, and the telescopic rod 33 itself will also move synchronously with the top rod 32 in the same direction.

[0072] Furthermore, a first threaded sleeve 311 is fixedly connected to the bracket body 31, and a second threaded sleeve 321 is fixedly connected to the top rod 32. Both ends of the telescopic rod 33 are threadedly matched with the first threaded sleeve 311 and the second threaded sleeve 321 respectively. Compared with the first threaded hole and the second threaded hole, the matching length between the telescopic rod 33 and the first threaded sleeve 311 and the second threaded sleeve 321 is longer, which can ensure a more stable and smooth structure. At the same time, when not in use, the two ends of the telescopic rod 33 can also be received in the first threaded sleeve 311 and the second threaded sleeve 321, thereby protecting the telescopic rod 33.

[0073] On the basis that the telescopic rod 33 is a screw rod, the present embodiment has the further beneficial effect that: the use of a double-headed screw rod can increase the feed amount of the push rod 32 each time the telescopic rod 33 rotates.

[0074] Optionally, a handle 34 is provided on the telescopic rod 33 , and the user can rotate the handle 34 to drive the telescopic rod 33 to rotate.

[0075] The handle 34 can be a disc handle 34 directly. In this case, the handle 34 and the telescopic rod 33 are coaxial, and the user can directly drive the telescopic rod 33 to rotate by rotating the handle 34 .

[0076] The handle 34 can also drive the telescopic rod 33 to rotate through the worm gear lifting mechanism. At this time, the rotating shaft of the handle 34 is perpendicular to the telescopic rod 33. This arrangement makes it easier for the user to rotate the handle 34.

[0077] The beneficial effect of this embodiment is that a variety of handle 34 structures that are convenient for users to use are provided, so that users can rotate the telescopic rod 33 more easily.

[0078] refer to Figure 1 , Figure 2 In one embodiment, the lifting rod assembly 2 includes a power assembly 24 and a rod 25 .

[0079] The power assembly 24 is connected to the rod 25 and can drive the rod 25 to rise and fall. The power assembly 24 is various commonly used retractable devices, such as an electric retractable cylinder, a pneumatic cylinder, a hydraulic cylinder or other similar retractable devices.

[0080] The rod 25 is detachably connected to the hanging beam 1 , and the rod 25 is used to provide support for the hanging beam 1 and drive the hanging beam 1 to move synchronously.

[0081] Optionally, there are at least two rods 25. When there are two rods 25, the two rods 25 are respectively located at both ends of the suspension beam 1, so that the suspension beam 1 is subjected to balanced force. When there are multiple rods 25, the rods 25 need to be evenly spaced and connected to the suspension beam 1, and do not interact with the flow channel 4.

[0082] The power assembly 24 includes a driving member 241 and at least two elevators 242 .

[0083] The number of the lifts 242 is the same as the number of the rods 25 , and each rod 25 is connected to a corresponding lift 242 , and the lift 242 can drive the rod 25 to move up and down.

[0084] There is one driving member 241, which is connected to each elevator 242 and provides power for it. The driving member 241 can drive each elevator 242 to rise and fall synchronously, thereby driving each rod 25 to rise and fall synchronously, so that each part of the suspension beam 1 can be subjected to force at the same time, thereby ensuring the balance of the suspension beam 1.

[0085] If the lift 242 is a cylinder, the driving member 241 is an air pump, and the driving member 241 and each lift 242 are connected by a pipeline; if the lift 242 is a hydraulic cylinder, the driving member 241 is a hydraulic pump, and the driving member 241 also includes an oil tank, and the driving member 241 and each lift 242 are connected by a pipeline; there can also be other similar combinations between the lift 242 and the driving member 241.

[0086] This embodiment provides a variety of specific structures of lifting rod assemblies 2, and its beneficial effect is: using a driving member 241 to simultaneously control multiple elevators 242 and control the synchronous lifting and lowering of multiple rods 25, so that various parts of the suspension beam 1 can be subjected to force at the same time, ensuring the balance of the suspension beam 1.

[0087] Furthermore, the rod 25 includes a middle portion 252 and a second end portion 253 which are connected in sequence.

[0088] The middle portion 252 is a bare rod for providing support.

[0089] The second end 253 is a screw, and the elevator 242 is a worm gear elevator. The second end 253 and the elevator 242 are connected via a coupling 243. The driving member 241 is a motor. The worm gear elevator can convert horizontal input into vertical output to drive the rod 25 to move up and down. The input shafts of multiple elevators 242 are linked by a long connecting rod and a coupling, so that the driving member 241 can drive multiple elevators 242 to move synchronously at the same time. At the same time, the worm gear elevator 242 has the advantages of compact structure, small size, light weight, low noise, easy installation, flexible use, high reliability and long service life.

[0090] The beneficial effects of this embodiment are: providing a specific structure of a rod 25, a lift 242 and a driving member 241, which has a long service life, is easy to control, has high reliability and is easy to install, so that the power component 24 can better control the lifting and lowering of the suspension beam 1.

[0091] refer to Figure 1 , Figure 2 In one embodiment, the rod 25 passes through the suspension beam 1 , and a pressing member 21 and a supporting member 22 are sleeved on the rod 25 and are respectively located on two sides of the suspension beam 1 and abut against the suspension beam 1 .

[0092] The support member 22 is located on the side of the suspension beam 1 facing the flow channel 4. The support member 22 is used to provide support for the suspension beam 1. When the lifting rod assembly 2 is lowered to the extreme position and the adjustment bracket 3 supports the suspension beam 1, the support member 22 is first lowered, and then the rod 25 is controlled to rise, so that the support member 22 is again against the suspension beam 1 and provides support for the suspension beam 1. At this time, the rod 25 can drive the suspension beam 1 to descend again.

[0093] The pressing member 21 is located at a side of the hanging beam 1 away from the flow channel 4 . The pressing member 21 is used to fix the hanging beam 1 . Under the action of the pressing member 21 and the supporting member 22 , the hanging beam 1 is fixed on the lifting rod assembly 2 .

[0094] The supporting member 22, the pressing member 21 and the rod member 25 may be matched in a bolt-type, thread-type or other similar matching manners.

[0095] Furthermore, the rod 25 further includes a first end portion 251 , which is fixedly connected to an end of the middle portion 252 away from the second end portion 253 , and an external thread is formed on the first end portion 251 .

[0096] The supporting member 22 and the pressing member 21 are both nuts and cooperate with the external threads.

[0097] A disc portion may be added to the side of the support member 22 facing the suspension beam 1 to increase the contact area between the support member 22 and the suspension beam 1. A stop nut threadedly matched with the first end portion 251 may be added to the side of the support member 22 away from the suspension beam 1 to ensure stable support for the suspension beam 1.

[0098] This embodiment provides a specific structure in which a support member 22, a clamping member 21 and a rod member 25 cooperate, and its beneficial effect lies in: arranging a threaded fit to facilitate the user to adjust the position of the support member 22 and the clamping member 21, and at the same time utilizing the self-locking ability of the threaded fit so that the support member 22 can stably support the suspension beam 1.

[0099] Optionally, a spring 23 is provided between the clamping member 21 and the suspension beam 1, one end of the spring 23 is against the suspension beam 1 and the other end is against the clamping member 21, and the spring 23 is always in a compressed state. During normal use, the spring 23 can stably hold the suspension beam 1 against the support member 22. If an erroneous operation causes the gate plate 5 to touch the bottom surface of the flow channel 4, the spring 23 will continue to compress, thereby preventing the gate plate 5 from continuously squeezing the flow channel 4 and causing damage to the flow channel 4, the gate plate 5 and the power assembly 24.

[0100] The beneficial effect of this embodiment is that a spring 23 is arranged between the clamping member 21 and the suspension beam 1, which effectively prevents damage to the flow channel 4, the gate plate 5 and the power assembly 24 due to misoperation, ensures that the device can have a longer service life, and can also reduce the impact on the entire processing process.

[0101] refer to Figure 6 In one embodiment, a gate adjustment method for a gate adjustment device is provided, comprising:

[0102] S1: Use the lifting rod assembly 2 to adjust the height of the gate 5;

[0103] In the initial state, the hanging beam 1 is located at the end of the rod 25. As the gate plate 5 is worn and corroded, the elevator 242 and the driving member 241 drive the hanging beam 1 through the rod 25 to gradually descend as it is worn and maintain the distance between the gate plate 5 and the bottom surface of the flow channel 4. When the rod 25 descends to the limit position, the rod 25 cannot continue to descend.

[0104] S2: When the lifting rod assembly 2 is lowered to the limit position, the control adjustment bracket 3 is extended to support the hanging beam 1;

[0105] The rotating handle 34 drives the telescopic rod 33 to rotate, thereby driving the top rod 32 to move toward the hanging beam 1. When the top rod 32 is against the hanging beam 1, the adjustment bracket 3 completes the temporary support.

[0106] S3: Remove the hanging beam 1 from the lifting rod assembly 2, control the lifting rod assembly 2 to rise, and reinstall the hanging beam 1 on the lifting rod assembly 2;

[0107] The position of the support member 22 is adjusted downward, and then the control rod 25 is extended to the limit position, and the position of the support member 22 is adjusted so that the support member 22 is against the suspension beam 1. At this time, the support member 22 can support the suspension beam 1 again.

[0108] It can be understood that in this step, the extension length of the rod 25 can be any length, but extending it to the extreme position can reduce the number of times the relative position of the suspension beam 1 is adjusted.

[0109] S4: Control and adjust the bracket 3 to retract;

[0110] Turn the handle 34 to drive the push rod 32 to move toward the bracket body 31, so that the push rod 32 and the hanging beam 1 are out of contact. In order to facilitate the further descent of the hanging beam 1, the push rod 32 can be adjusted to the position closest to the bracket body 31;

[0111] The adjusting bracket 3 can be taken out afterwards, or the adjusting bracket 3 can be left under the suspension beam 1 .

[0112] When the lifting rod assembly 2 descends to the limit position again, steps S1 to S4 are repeated.

[0113] It should be noted that, due to the heavy weight of the suspension beam 1 and the gate plate 5, when the push rod 32 contacts and supports the suspension beam 1, continuing to turn the handle 34 will obviously feel a greatly increased resistance. At this time, you can stop turning the handle 34 to prevent the push rod 32 from continuing to extend and lift the suspension beam 1 and cause the position of the suspension beam 1 to change. On this basis, you can also insert a feeler gauge between the push rod 32 and the suspension beam 1 when you feel resistance, and use the feeler gauge to determine whether the push rod 32 is firmly pushed.

[0114] It should be noted that when the rod 25 is extended again and the support member 22 is adjusted to be against the suspension beam 1, it is also possible to determine whether the support member 22 is firmly pressed by adjusting the resistance and the feeler gauge.

[0115] The beneficial effects of this application are:

[0116] 1. Use the liftable lifting rod assembly 2 to support the hanging beam 1, and adjust the height of the hanging beam 1 through the lifting rod assembly 2 according to the loss of the gate plate 5 to improve the utilization rate of the gate plate 5;

[0117] 2. An adjustment bracket 3 for temporary support is provided to temporarily support the hanging beam 1 when the lifting rod assembly 2 reaches the lowering limit position, so that the lifting rod assembly 2 can be removed from the hanging beam 1 and reconnected with the hanging beam 1 after lifting, thereby realizing the adjustment of the relative position of the hanging beam 1 and the lifting rod assembly 2, expanding the lifting range of the lifting rod assembly 2 without stopping the machine, and further improving the utilization rate of the gate plate 5.
