In this embodiment, when the channel glass liquid stirring device is used, the bracket 11 of the lifting mechanism 1 and the original upright post of the tin bath are arranged on the upright post, so that when the first power device 13 drives the lifting mechanism 12 to operate, the up-and-down moving end of the lifting mechanism 12 drives the linear reciprocating mechanism 2 to move to a set position along the up-and-down direction relative to the upright post and the tin bath. The molten tin bath is provided with the flow channel, and molten glass flows through the flow channel. In this embodiment, the lifter 12 is a ball screw lifter or a turbine lifter, so that the lifter 12 can drive the linear reciprocating mechanism 2 to move up and down, and meanwhile, the lifter has a simple overall structure and a small volume.
As shown in fig. 1 and 2, in this embodiment, there are two lifters 12, the output shaft of the first power device 13 is connected to one of the lifters 12, and the two lifters 12 are connected by a universal coupling 14.

Under normal conditions, the double-output shaft motor 131 will directly provide power and drive the elevator 12 to run; however, in special situations, such as emergency situations, the manual driving wheel 15 can be manually rotated to drive the output shaft of the double-output shaft motor 131 to rotate, and the output shaft of the double-output shaft motor 131 drives the elevator 12 to operate, so that under the manual action, the output shaft of the double-output shaft motor 131 drives the elevator 12 to operate. Meanwhile, in the embodiment, the manual wheel 15 is a sprocket, and a chain is installed on the manual wheel 15, so that a person can drive the sprocket, namely the manual wheel 15 to rotate by pulling the chain, and further drive the output shaft of the double-output-shaft motor 131 and the lifter 12 to operate; and under the condition that the position of the manual wheel 15 is higher, the manual wheel 15 is driven to rotate by pulling one end of the chain which falls downwards conveniently.
As shown in fig. 4, in this embodiment, a travel switch 41 is installed on the bracket 11, the travel switch 41 is connected with a controller, and the controller is connected with the first power device 13; when the up-down moving end of the lifter 12 drives the linear reciprocating mechanism 2 to move to the set position, the travel switch 41 sends a signal to the controller, and the controller controls the output shaft of the first power device 13 to stop running so as to prevent the moving distance of the lifter 12 driving the linear reciprocating mechanism 2 from exceeding the set travel. In this embodiment, two travel switches 41 are mounted on the bracket 11, and the two travel switches 41 are distributed at intervals in the up-down direction. In the process that the vertical moving end of the lifter 12 drives the linear reciprocating mechanism 2 to move upwards, when the vertical moving end of the lifter 12 drives the linear reciprocating mechanism 2 to move upwards to a set position, the travel switch 41 positioned above senses the linear reciprocating mechanism 2 and sends a signal to the controller, the controller controls the braking action of the double-output-shaft motor 131, the output shaft of the double-output-shaft motor 131 is locked by the braking action, so that the output shaft of the double-output-shaft motor 131 stops rotating, and the lifter 12 stops driving the linear reciprocating mechanism 2 to move upwards to ensure that the linear reciprocating mechanism 2 and the stirring rod 3 can stop at the set position after moving upwards. In the process that the up-and-down moving end of the lifter 12 drives the linear reciprocating mechanism 2 to move downwards, when the up-and-down moving end of the lifter 12 drives the linear reciprocating mechanism 2 to move downwards to a set position, the travel switch 41 positioned below senses the linear reciprocating mechanism 2 and sends a signal to the controller, the controller controls the braking action of the double-output-shaft motor 131, the braking locks the output shaft of the double-output-shaft motor 131, so that the output shaft of the double-output-shaft motor 131 stops rotating, and the lifter 12 stops driving the linear reciprocating mechanism 2 to move downwards to ensure that the linear reciprocating mechanism 2 and the stirring rod 3 can stop at the set position after moving downwards to the set position. The present embodiment ensures that the lifter 12 can reciprocate along a set stroke in the up-down direction by using the above-described two stroke switches 41. The double-output motor 131 in this embodiment is an ac motor.
As shown in fig. 1, 3, 6 and 7, the linear reciprocating mechanism 2 in this embodiment includes a bracket 21 fixedly connected with the lifting mechanism 1, a linear module 22 mounted on the bracket 21, and a second power device 23 connected with the linear module 22, and the linear module 22 includes a guide rail 221 mounted on the bracket 21, a slide block 222 mated with the guide rail 221, and a ball screw 223 screwed with the slide block 222, wherein an output shaft of the second power device 23 is connected with the ball screw 223, and the slide block 222 is fixedly connected with the stirring rod 3. In the stirring process, the second power device 23 drives the ball screw 223 to rotate, and under the action of threaded connection and the cooperation of the sliding block 222 and the guide rail 221, the sliding block 222 drives the stirring rod 3 to slide along the guide rail 221 together, and the stirring rod 3 realizes stirring of molten glass in the sliding process along the guide rail 221.
As shown in fig. 3, the linear reciprocating mechanism 2 in this embodiment further includes a limit stop 24 mounted on the carriage 21, the limit stop 24 being used to limit the travel of the slider 222 sliding along the guide rail 221. When the sliding distance of the sliding block 222 along the guide rail 221 reaches the set travel, the sliding block 222 contacts with the limit stop 24, so that the limit stop 24 limits the sliding block 222 to continue sliding, and the sliding distance of the sliding block 222 and the stirring rod 3 is prevented from exceeding the set travel. The limit stop 24 in this embodiment is used to limit the travel of the slider 222 and the stirring bar 3 in a direction away from the tin bath.
As shown in fig. 3 and 5, in this embodiment, the bracket 21 is provided with the proximity switch 42, and the proximity switch 42 is connected to the controller, and the controller is connected to the second power device 23, and when the slider 222 slides along the guide rail 221 to a set position, the proximity switch 42 sends a signal to the controller, and the controller controls the output shaft of the second power device 23 to stop running, so as to avoid that the sliding distance of the slider 222 driving the stirring rod 3 exceeds the set stroke. The guide rail 221 in this embodiment is a linear guide rail 221, and the guide rail 221 extends in the left-right direction. Meanwhile, in the present embodiment, the second power device 23 is a servo motor 231, and the servo motor 231 is used to provide driving power for the linear reciprocating mechanism 2, so that the sliding block 222 and the stirring rod 3 can be accurately and rapidly positioned in the linear motion process, and the sliding speed of the sliding block 222 can be adjusted. The linear module 22 in this embodiment adopts the above structure, so that the slider 222 can move smoothly and rapidly along the linear direction. In this embodiment, 3 proximity switches 42 are mounted on the bracket 21, and the 3 proximity switches 42 are distributed at intervals in the left-right direction. In the process that the slide block 222 drives the stirring rod 3 to reciprocate in the left-right direction to stir glass liquid, when the slide block 222 drives the stirring rod 3 to move rightwards to a set position, the rightmost proximity switch 42 senses the slide block 222 and sends a signal to the controller, and the controller controls the servo motor 231 to stop driving the ball screw 223 to rotate in the original direction, so that the slide block 222 does not move rightwards any more; when the slide block 222 drives the stirring rod 3 to move leftwards to the set position, the proximity switch 42 in the middle senses the slide block 222 and sends a signal to the controller, and the controller controls the servo motor 231 to stop driving the ball screw 223 to rotate along the original direction, so that the slide block 222 does not move leftwards any more, and the slide block 222 is ensured to drive the stirring rod 3 to reciprocate in the set stroke in the left-right direction. When the stirring rod 3 needs to withdraw from the molten glass, the sliding block 222 drives the stirring rod 3 to move leftwards to a withdraw position, and at the moment, the leftmost proximity switch 42 senses the sliding block 222 and sends a signal to the controller, and the controller controls the servo motor 231 to stop driving the ball screw 223 to rotate along the original direction. The above-described exit position serves as an origin point at which the slider 222 moves in the left-right direction. The proximity switch 42 located in the middle and the proximity switch 42 located at the rightmost side correspond to turning points of the stirring rod 3 for reciprocally stirring the molten glass, respectively.
The slider 222 constitutes a horizontal movement end of the linear reciprocating mechanism 2. The slide block 222 is fixedly connected with the stirring rod 3 through a clamp so as to facilitate quick disassembly and replacement of the stirring rod 3. The bracket 11 of the lifting mechanism 1 is fixed on the original upright post of the tin bath, so that the relative positions of the whole flow channel glass liquid stirring device and the stirring port on the tin bath are fixed, and the influence of displacement generated by thermal deformation on the positioning of the flow channel glass liquid stirring device is reduced. In this embodiment, the flow path glass liquid stirring device is positioned at the left side of the tin bath. The two lifters 12 are spaced apart in the left-right direction, the lifter 12 located at the left is farther from the tin bath, and the lifter 12 located at the right is closer to the tin bath. Meanwhile, in the present embodiment, the output shaft of the double-output shaft motor 131 is specifically directly connected to the lifter 12 far from the tin bath. The lifters 12 are fixed on the bracket 11, and the two lifters 12 are connected through the universal coupling 14, so that the up-and-down moving ends of the two lifters 12 are ensured to synchronously lift, and thus, the up-and-down moving ends of the two lifters 12 synchronously drive the linear reciprocating mechanism 2 to lift, and the linear reciprocating mechanism 2 is prevented from tilting in the lifting process. The lifting mechanism 1 can realize the adjustment of the depth of the stirring rod 3 inserted into the molten glass in the process of driving the linear reciprocating mechanism 2 and the stirring rod 3 to move along the up-down direction. In addition, the double-output-shaft motor 131 can provide driving power in two modes of manual and electric for the lifting mechanism 1, so that the stirring rod 3 can be lifted away from glass liquid in an emergency by manually operating the manual wheel 15.
As shown in fig. 2, the vertically movable end of the lifter 12 has a connection flange 121, the bracket 21 of the linear reciprocating mechanism 2 is fixedly connected to the connection flange 121, and the linear module 22 is fixed to the bracket 21. The linear reciprocating mechanism 2 is suspended and fixed on the lifter 12. Thus, the lifter 12 can move the carriage 21 and the linear reciprocating mechanism 2 in the up-down direction.
As shown in fig. 1 and 3 to 5, the controller, the proximity switch 42, and the travel switch 41 are all part of the control system 4. And the control system 4 further comprises a flashlight switch. The flashlight switch can switch the whole flow passage glass liquid stirring device to be in a manual working mode or an electric working mode. The proximity switch 42 is used to position the origin of the linear reciprocating mechanism 2, and then to position and detect the return point of the working stroke during operation. The control system 4 feeds back the field working signal to the upper computer through the sensor signal, and then the controller sends out the next working instruction of the device. In this embodiment, the limit stop 24 is fixed to the bracket 21, so that the limit stop 24 can prevent the moving distance of the slider 222 and the stirring rod 3 from exceeding the set travel and causing damage when the control system 4 fails. The limit stop 24 is fixed to the side of the bracket 21. In this embodiment, the controller employs a PLC.
The stirring rod 3 comprises two types of choices in the embodiment; a stirring rod 3 is provided with a water cooling structure, so that the heated deformation of a rod body is reduced, and the stirring rod 3 is safer and more durable; the other stirring rod 3 is made of heat-resistant materials, and the stirring rod 3 is simple in integral structure and does not need water.
When in use, the stirring rod 3 needs to extend into the flow channel of the tin bath; therefore, the double-output-shaft motor 131 drives the linear reciprocating mechanism 2 and the stirring rod 3 to be lifted to a position 50mm away from the flow passage edge of the tin bath from the lowest position by driving the lifter 12, and then the servo motor 231 drives the stirring rod 3 to move rightwards from the original position by driving the linear module 22, and the stirring rod 3 stretches into the flow passage of the tin bath; the double-output-shaft motor 131 drives the lifter 12 to act again so as to put the stirring rod 3 into molten glass to the depth required by the process; thus, after the stirring rod 3 is in place, the servo motor 231 drives the linear reciprocating mechanism 2, and the stirring rod 3 makes linear reciprocating motion at a set speed in a set stroke, namely, the stirring rod 3 makes reciprocating motion between two turning points and along a straight line so as to realize stirring of molten glass; during the stirring process, the proximity switch 42 positioned in the middle and at the rightmost direction detects whether the sliding block 222 and the stirring rod 3 reciprocate according to the set reciprocation point, and the movement track of the sliding block 222 is controlled by the controller. Meanwhile, under the condition of power failure, the whole flow channel glass liquid stirring device can be switched to a manual mode through the flashlight switch, so that the manual wheel 15 and the chain can be manually rotated, the height of the stirring rod 3 can be adjusted, or the stirring rod 3 can be lifted out of a tin bath in emergency, and the travel switch 41 can detect and ensure that the travel of the stirring rod 3 does not exceed the set travel when the stirring rod 3 moves up and down so as to avoid interference. When the linear movement station of the stirring rod 3 is required to be manually adjusted or the stirring rod 3 is required to be assembled, disassembled and replaced, the clamp can be manually pulled, so that the position of the stirring rod 3 reaches the required position. The limit stop 24 effectively ensures that the clamp and the stirring rod 3 do not exceed a safety stroke when in linear reciprocating operation when manual misoperation or electrical control fails.
The flow channel molten glass stirring device in the embodiment is specifically used for stirring molten glass in a molten glass tin bath flow channel of the plate glass. The stirring rod 3 of the present flow path glass liquid stirring device is configured to stir glass liquid by reciprocating along the guide rail 221, that is, along a straight line, and the present flow path glass liquid stirring device is also referred to as a glass flow path straight line stirring device. When the glass liquid stirring device for the flow channel is used, the uniformity of glass liquid is further optimized; and the whole structure is simple, and the volume is smaller, thereby overcoming the difficulties of large operation limitation and space constraint encountered by the prior stirring device. The flow channel glass liquid stirring device has higher running stability when in use. By adopting the linear reciprocating mechanism 2 and the stirring rod 3, not only is the stirring of glass liquid realized, but also the whole structure of the glass liquid stirring device with the flow channel is concise, and the device can stably and accurately reciprocate along a straight line according to the requirements of technological parameters in limited space, is convenient for adjusting the working position of the device in real time, and is also convenient for maintaining the device when required.
In summary, the present invention effectively overcomes the disadvantages of the prior art and has high industrial utility value.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
