Description

Technical Field

[0001] This utility model relates to an auxiliary facility for photovoltaic glass calendering and molding production, specifically to a device for preventing lip brick from collapsing. Background Technology

[0002] Photovoltaic rolled glass is produced by flowing molten glass through the lip brick, a key component of the furnace overflow, and then being pressed and cooled by the rolling mill rolls. The lip of the lip brick and the guard brick on it are inserted between the upper and lower rolling mill rolls. Due to the special requirements of the production process, the gap between the lip and the lower rolling mill roll is very small. During production, due to the continuous flow and impact of the molten glass and the temperature changes during the washing of the lower roll, the state of the lip brick support changes, causing the lip of the lip brick to move towards the lower rolling mill roll. This is known as the lip brick head-carrying phenomenon. As the lip brick head-carrying continues, the gap between the lip and the lower rolling mill roll becomes smaller and smaller. If not handled carefully, the end of the guard brick on the lip brick can touch and damage the lower rolling mill roll, leading to machine replacement and significant economic losses.

[0003] In the current production process, especially when washing the lower calender rolls, it is necessary to pre-divide the calender to increase the gap between the lip and the lower calender rolls, or to divide the machine while operating. After the lower rolls are washed and stabilized, the calender is gradually returned to its original position. Although this is a relatively effective way to prevent damage to the lower calender rolls, continuous division will cause the gap between the middle part of the lip and the lower calender rolls to increase. The glass melt in this area will be more susceptible to external environmental influences and defects will appear. Therefore, other methods should be found to solve this problem. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides a device to prevent the lip brick from falling off.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for preventing lip brick from collapsing is installed between the overflow port wall of a furnace and a lip brick support. The device includes a left tensioning arm and a right tensioning arm arranged in mirror images. One end of the left tensioning arm is a left force-applying end, and the other end is a left connecting end, which is connected to the overflow port wall of the furnace. One end of the right tensioning arm is a right force-applying end, and the other end is a right connecting end, which is connected to the lip brick support. A force-applying mechanism is provided between the left force-applying end and the right connecting end, which is used to adjust the relative distance between the left force-applying end and the right force-applying end.

[0007] Furthermore, the left force-applying end is a left-handed screw, and the right force-applying end is a right-handed screw, with the left-handed and right-handed screws having opposite directions of rotation;

[0008] The force-applying mechanism includes a left-hand screw hole and a right-hand screw hole arranged in a mirror image, and the left-hand screw hole and the right-hand screw hole are fixedly connected by a connecting bracket; wherein the left-hand screw hole is threadedly connected to the left-hand screw rod, and the right-hand screw hole is threadedly connected to the right-hand screw rod.

[0009] Furthermore, the connecting frame is fixedly provided with a force-applying ring coaxial with the left-hand screw hole and the right-hand screw hole, and the force-applying ring is provided with force-applying holes and / or force-applying rods arranged in the circumferential direction.

[0010] Furthermore, the left connecting end is a left tensioning hook; the right connecting end is a right tensioning hook.

[0011] Furthermore, the left tensioning arm and the right tensioning arm are arranged in a straight line.

[0012] Furthermore, an action frame is fixed to the wall of the overflow port of the furnace, and the left connecting end is connected to the action frame; an action rod is fixed to the lip brick support, and the left connecting end is connected to the action rod.

It effectively prevents the lip brick support from deviating during production due to the impact of the glass melt flow or the effect of temperature changes during the washing of the lower roller, thereby avoiding the phenomenon of the lip brick bearing the head. This also avoids the roller damage caused by the guard brick touching the lower rolling roller after the lip brick bearing the head, thus avoiding glass defects and machine replacement events.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1 to 4 As shown, this embodiment provides a device to prevent lip brick from collapsing, which is installed between the overflow port wall 401 of the furnace and the lip brick support 402. The lip brick 403 is installed on the lip brick support 402, and the lip of the lip brick 403 and the guard brick 404 on the lip brick 403 are inserted between the upper calendering roller 405 and the lower calendering roller 406.

[0025] Specifically, the device for preventing the lip brick from collapsing includes a left tensioning arm 101 and a right tensioning arm 102 that are mirror images of each other and arranged in a straight line. The left tensioning arm 101 and the right tensioning arm 102 act on the overflow port wall of the furnace and the lip brick support, respectively, and tighten the two through the action of the force application mechanism.

[0026] One end of the left tensioning arm 101 is the left force-applying end, and the other end is the left connecting end. Specifically, the left force-applying end is the left-hand screw 103, and the left connecting end is the left tensioning hook 105. An actuating frame 301 is fixed at the overflow port wall 401 of the furnace, and the left tensioning hook 105 hooks onto the actuating frame 301.

[0027] One end of the right tensioning arm 102 is the right force-applying end, and the other end is the right connecting end. Specifically, the right force-applying end is a right-hand screw 104, which rotates in the opposite direction to the left-hand screw 103. The right connecting end is a right tensioning hook 106. An actuating rod 302 is fixed at the lip brick bracket 402, and the right tensioning hook 106 hooks onto the actuating rod 302.

[0028] A force-applying mechanism is provided between the left-hand screw 103 and the right-hand screw 104. The force-applying mechanism is used to adjust the relative distance between the left-hand screw 103 and the right-hand screw 104 to achieve tension.

[0029] In this embodiment, the force-applying mechanism includes a left-hand screw hole 201 and a right-hand screw hole 202 arranged in a mirror image. The left-hand screw hole 201 and the right-hand screw hole 202 are fixedly connected by a connecting bracket. The left-hand screw hole 201 is threadedly connected to the left-hand screw 103, and the right-hand screw hole 202 is threadedly connected to the right-hand screw 104.

[0030] The connecting frame is also fixed with a force-applying ring 203 coaxial with the left-hand screw hole 201 and the right-hand screw hole 202. Force-applying holes 205 and force-applying rods 204 are alternately arranged along the circumference on the force-applying ring 203. Both the force-applying holes 205 and the force-applying rods 204 can be used as points of application for adjusting the tension force.

[0031] The installation of this utility model is as follows:

[0032] like Figure 4 As shown, the action frame 301 is welded to the side of the overflow port wall 401 of the furnace, and the action rod 302 is welded to the bottom of the lip brick support 402. The left tension arm 101 and the right tension arm 102 are connected to the left-hand screw hole 201 and the right-hand screw hole 202 of the force application mechanism 2, respectively. The left tension hook 105 and the right tension hook 106 of the left tension arm 101 and the right tension arm 102 are hooked onto the action frame 301 and the action rod 302, respectively. The force application ring 203 is rotated to the right to tighten the entire device. The entire installation is completed. It can be easily disassembled and installed whether the machine is stopped or in normal production.

[0033] Depending on the equipment requirements, one or more sets of devices to prevent the lip brick from falling off can be installed.

[0034] The working principle of this utility model is as follows:

[0035] The right-hand force ring 203, because the left tension arm 101 and the left-hand screw hole 201 are both left-handed structures, and the right tension arm 102 and the right-hand screw hole 202 are both right-handed structures, will gradually apply tension to the anti-head-carrying device, tightly holding the lip brick support 402 so that its position does not change, thereby ensuring the stability of the lip brick and guard brick positions, preventing the occurrence of head-carrying phenomenon, and avoiding the roller damage caused by the guard brick touching the lower pressure roller after the lip brick head-carrying, thus avoiding glass defects and machine replacement events.

[0036] This utility model has a simple structure, is easy to install and disassemble, and is flexible and convenient to adjust during the process. The force ring 203 has a force bar 204 and a force hole 205, which can be used as the point of application for adjusting the tension force.
