Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a wiring structure of an edge drawing machine used in a one-kiln multi-line float glass production line. Background Art

[0002] The float glass process is a process that uses the floating characteristics of the metal tin liquid surface and the influence of the tin liquid temperature field to gradually flatten, polish, and shape the molten glass under the combined effects of gravity, surface tension, viscosity, and pulling force, and to make the glass ribbon have a balanced thickness value. This process needs to be carried out in a specific temperature control area to ensure the molten state of the glass liquid and the stability of the tin liquid temperature field. Under natural conditions, the equilibrium thickness of the glass ribbon is 6.85mm. If you need to manufacture a glass plate with a thickness exceeding or below the equilibrium thickness, you must use a side drawing machine. In this way, you can control the thickness of the glass by changing the stretching speed of the glass during the forming process.

[0003] The glass edge drawing machine is a main forming equipment dedicated to the float glass production line. Its main function is to pull the glass ribbon floating on the tin bath liquid surface forward through the edge drawing wheel, and to control the thickness of the glass ribbon and stabilize the width of the glass plate by adjusting the linear speed of the edge drawing wheel and its horizontal deflection angle, plane inclination, etc. During the use of the edge drawing machine, the swing of its tail is part of its daily activities. Therefore, it is necessary to set a cable that can move synchronously with the edge drawing machine.

[0004] In a one-kiln-one-line float glass production line, the wiring method is: a steel wire rope is set diagonally above the tail, and the cables coming out of the cable tray are wrapped into a wire harness through a buckle-type cable end belt, and a pulley hook is installed at a suitable position in the middle of the wire harness, and then the pulley of the pulley hook is set on the steel wire rope, so that when the tail of the edge drawing machine swings, the pulley hook also moves left and right on the steel wire rope, driving the cable to move with the edge drawing machine. However, this wiring method takes up a lot of space. In a one-kiln-one-line float glass production line, there is enough space at the tail of the edge drawing machine, so the above method can be used.

[0005] However, following the large-scale development of float glass melting furnaces, in order to meet the rapid changes in the glass market, the one-kiln-one-line float glass production line has undergone major technological innovations to form a float glass one-kiln-multiple-line production line. One-kiln-multiple-line has been widely used for its advantages of low energy consumption, good product quality, a full range of glass thicknesses and stable production. However, based on the production requirements of one-kiln-multiple-line float glass, in general, the edge drawing machines between the two tin baths are very close to each other, especially after the installation of cables and air pipes, the movement of the swing angle of a single edge drawing machine is very easy to scratch the cables and air pipes of the adjacent edge drawing machines, which can easily cause damage to the cables and air pipes. In more serious cases, the cables may be broken due to cable entanglement. Therefore, how to ensure the normal operation of the edge drawing machine in the limited space between the tin baths in the one-kiln-multiple-line float glass production line has become a problem that needs to be faced now. Summary of the invention

[0006] The technical problem solved by the present invention is: how to ensure the normal swinging operation of the edge drawing machine in the limited space between the tin baths in a multi-line float glass production line with one kiln.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A wiring structure of a side drawing machine for a multi-line float glass production line in one kiln, comprising:

[0009] Cable tray;

[0010] A support member, wherein the support member is arranged at an obliquely upper position of the edge drawing machine;

[0011] An automatic wire take-up device, the automatic wire take-up device being slidably disposed on the support member;

[0012] The cable is led out through the cable tray and then rolled into the automatic wire take-up device, and then led out through the outlet of the automatic wire take-up device and connected to the tail of the edge drawing machine.

[0013] In one embodiment of the present invention, the support member is a steel wire rope.

[0014] In one embodiment of the present invention, the automatic wire take-up device is a spring-type automatic wire take-up device.

[0015] In one embodiment of the present invention, a through hole is provided at the center of the automatic wire take-up device, and the support member is inserted into the through hole.

[0016] In one solution of the present invention: a protective structure is provided on the cable.

[0017] In one embodiment of the present invention, the protective structure is a three-dimensional drag chain.

[0018] The wiring structure of the edge drawing machine for a multi-line float glass production line in one kiln according to the present invention has at least one of the following technical effects:

[0019] Beneficial effects of the present invention:

[0020] By reserving the length of the cable in the spring-type automatic wire take-up device and the cable length from the outlet to the tail of the edge drawing machine during the installation process, when the tail of the edge drawing machine moves, the reserved cable in the wire take-up device can be easily pulled out or retracted to ensure that there is no excess cable at the tail of the edge drawing machine, preventing the edge drawing machine that is very close to it from scratching and causing damage to the cable and causing accidents.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The glass edge drawing machine is a main forming equipment dedicated to the float glass production line. Its main function is to pull the glass ribbon floating on the tin bath liquid surface forward through the edge drawing wheel, and to control the thickness of the glass ribbon and stabilize the width of the glass plate by adjusting the linear speed of the edge drawing wheel and its horizontal deflection angle, plane inclination, etc. During the use of the edge drawing machine, the swing of its tail is part of its daily activities. Therefore, it is necessary to set a cable that can move synchronously with the edge drawing machine.

[0031] See also Figure 1 In the existing float glass production line, the routing method is as follows: a steel wire rope is arranged obliquely above the tail, and the cable 2 coming out of the cable tray 1 is wrapped into a wire harness through the buckle cable 2 end belt, and then a pulley hook 3 is installed at a suitable position in the middle of the wire harness, and then the pulley of the pulley hook 3 is arranged on the steel wire rope, so that when the tail of the edge drawing machine makes a swinging motion, the pulley hook 3 also moves on the steel wire rope, driving the cable 2 to move with the edge drawing machine. However, this routing method takes up a lot of space. In the production line of float glass with one kiln and multiple lines, based on the production requirements of float glass with one kiln and multiple lines, in general, the distance between the edge drawing machines between the two tin baths is very close to each other, especially after the cables and air pipes are installed, the movement of the swing angle of a single edge drawing machine is very easy to scratch the cables and air pipes of the adjacent edge drawing machines, which is easy to cause damage to the cables and air pipes. In more serious cases, the cable 2 may be pulled apart due to the entanglement of the cable 2. Therefore, how to ensure the normal operation of the edge drawing machine in the limited space between the tin baths in a multi-line float glass production line in one kiln has become a problem that needs to be faced now.

[0032] See also Figure 2-3In the present application, a wiring structure of a drawer for a multi-line float glass production line in one kiln is provided, comprising a cable tray 1, a support, an automatic wire take-up device 4 and a cable 2; the cable 2 is drawn out from the cable tray 1 and then inserted into a three-dimensional drag chain, and then the cable 2 is rolled into a spring-type automatic wire take-up device 4 together with the three-dimensional drag chain, and after retaining a suitable length of the cable 2, the cable 2 is drawn out from the outlet of the wire take-up device and directly connected to the tail of the drawer. During the use of the drawer, the swing of its tail is part of daily activities. At this time, the three-dimensional drag chain is used to supply energy, safely guide and protect the drawer cable 2. At the same time, thanks to its high tensile force absorption (mechanical stress) and high flexibility, the three-dimensional drag chain can carry the cable 2 and rotate each link by about ±10° in complex movements. Furthermore, the sliding connection between the automatic wire take-up device 4 and the support can also provide a follow-up space for the cable 2 to a certain extent. The supports on both sides are arranged in parallel, and when the redundant cables 2 are gathered by the automatic wire take-up device 4, there is no confusion or entanglement of the cables 2. Through the setting of this application, firstly, it can ensure that each edge drawing machine can be used normally, secondly, it can prevent the cable 2 from being broken on site when the operator is remotely controlling in the control room, and thirdly, the cable 2 on site is in order instead of being chaotic.

[0033] See also Figure 2-3 The present invention is a wiring structure for a drawer for a multi-line float glass production line in one kiln, comprising a cable tray 1, a support, an automatic wire take-up device 4 and a cable 2; the cable tray 1 is fixedly arranged on a column for supporting the laying of the cable 2. The support is arranged at an obliquely upper position of the drawer; it can be a steel wire rope. A support rod can also be selected. Both ends of the support are fixedly arranged.

[0034] See also Figure 2-3 In one embodiment of the present invention, the automatic wire take-up device 4 is slidably arranged on the support member; thus, it can slide along the support member, and then when the edge drawing machine moves, the automatic wire take-up device 4 can move a certain distance with the edge drawing machine through the movable arrangement. The automatic wire take-up device 4 can be a spring-type automatic wire take-up device 4. The automatic wire take-up device 4 can be slidably arranged on the support member through a bracket structure. A through hole can also be arranged in the center of the automatic wire take-up device 4, and the support member is penetrated in the through hole. Thereby, the sliding of the automatic wire take-up device 4 is realized, and the through hole arranged in the center can ensure the stability and smoothness of the wire take-up device when it rotates.

[0035] See also Figure 2-3In one embodiment of the present invention, the cable 2 is drawn out through the cable tray 1 and then rolled into the automatic wire take-up device 4, and then drawn out through the outlet of the automatic wire take-up device 4 and connected to the tail of the edge drawing machine so as to power the edge drawing machine. The cable 2 is rolled into the automatic wire take-up device 4, so that the cable 2 of the edge drawing machine can automatically retract under the action of the wire take-up device during the movement, ensuring the use of the edge drawing machine while avoiding the possibility of overlapping of the cable 2 at the tail of the edge drawing machine in space. A protective structure may be provided on the cable 2 to protect the cable 2. The protective structure may be a flexible sleeve, a belt insulation sleeve, etc. Preferably, the protective structure is a three-dimensional drag chain. During the use of the edge drawing machine, the swing of its tail is part of daily activities. At this time, the edge drawing machine cable 2 is safely guided and protected by using a three-dimensional drag chain for energy supply. At the same time, thanks to its high tensile force absorption (mechanical stress) and high flexibility, the three-dimensional drag chain can carry the cable 2 and each link can rotate about ±10° in complex movements.
