Description

Technical Field

[0001] The utility model generally relates to the technical field of glass production technology, and in particular to a steering device for glass production. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt, which is an amorphous solid with irregular structure. It is widely used in buildings to block wind and transmit light, and is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass.

[0003] At present, in an ultra-thin glass production process, the glass will have a process of being transferred from the hot end to the cold end finishing section after being formed. During the transfer, the flow direction of the glass changes from vertical to parallel. According to the requirements of process quality control, the curvature of the glass needs to be gradually controlled so that the curvature of the glass has a gradual control process from the beginning of the flow to the glass state when it is stable. However, the existing steering device has the technical problem of being unable to accurately and effectively control the transfer state of ultra-thin glass, resulting in a low yield rate of the product. For example, the patent application for a glass linear steering mechanism with application number 201310566590.X. Utility Model Content

[0004] The present application provides a steering device for glass production to solve the technical problem in the prior art that the transmission state of ultra-thin glass cannot be accurately and effectively controlled, resulting in a low product yield.

[0005] The present application provides a steering device, comprising: a bracket, an upper pressure roller and a movable support, wherein the upper pressure roller is arranged above the bracket; the movable support can be rotatably arranged on the bracket, and the angle of the movable support relative to the upper pressure roller is adjusted by a driving system.

[0006] Furthermore, transmission rollers are provided at both ends of the movable support, and the two transmission rollers are connected by a conveyor belt.

[0007] Furthermore, the rotating shaft of one of the transmission rollers is connected to the bracket via a bearing.

[0008] Furthermore, the rotating shaft is driven by a first servo motor.

[0009] Furthermore, the upper pressing roller is driven by a second servo motor, or the upper pressing roller is connected to the rotating shaft via a transmission mechanism.

[0010] Furthermore, the driving system includes a connecting shaft, a driving member, a mounting seat and a fixed base plate, the movable end of the driving member is rotatably connected to the movable support via the connecting shaft, and the fixed end of the driving member is mounted on the fixed base plate via the mounting seat.

[0011] Furthermore, the mounting seat is connected to the fixed base plate via a bearing, and the mounting seat can rotate relative to the fixed base plate.

[0012] Furthermore, the driving member adopts an electric cylinder, and the extension and retraction of the electric cylinder is adjusted by a control system.

[0013] Furthermore, the position of the upper pressing roller can be adjusted relative to the bracket.

[0014] Furthermore, the diameters at both ends of the upper pressing roller are larger than the center diameter.

[0015] It can be seen from the above technical scheme that the advantages and positive effects of a steering device of the utility model are: when the ultra-thin glass flows down in the early stage of production, the glass belt is incomplete because the process parameters and equipment status have not yet reached the best. At this time, the movable support is adjusted by the drive system to make the movable support to the highest position, so that the glass can flow directly into the broken glass groove below, avoiding poorly formed glass from entering the production line. When the glass forming state gradually improves, the movable support is adjusted by the drive system so that the conveyor belt on the movable support and the glass are connected and matched to a certain extent. The upper pressure roller gradually matches the preset position of the glass and the movable support as the glass flows, so that the glass maintains a certain angle and contact strength during the transmission process, so that the glass has a good steering. The above scheme effectively solves the technical problem that the existing steering device cannot accurately and effectively control the transmission state of ultra-thin glass, resulting in a low product yield.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] like Figure 1 As shown, a steering device of the embodiment includes: a bracket 1, an upper pressure roller 2 and a movable support 3, wherein the upper pressure roller 2 is arranged above the bracket 1; the movable support 3 is rotatably arranged on the bracket 1, and the angle of the movable support 3 relative to the upper pressure roller 2 is adjusted by the driving system 4. It is particularly noted that a broken glass trough can be arranged below the bracket 1 to facilitate the collection of early production waste; regarding the movable support 3, a triangular structure is adopted in the drawings of the present application. Since the triangular structure has stability, it is used as the best implementation scheme of the present application, but it does not mean that implementation schemes such as squares, rectangles and other shapes are excluded, and structures equivalent to the above principles should be included in the protection scope of the present application; the movable support 3 is rotatably arranged on the bracket 1, that is, the movable support 3 can rotate around the bracket 1, and the movable support 3 and the bracket 1 can be connected by a bearing.

[0030] like Figure 1As shown, in the technical solution of the first embodiment, the movable support 3 adopts an inverted triangle structure, and its vertices are divided into a left vertex, a right vertex and a lower vertex. The right vertex is connected to the bracket 1 through a revolute pair, and the lower vertex is connected to the drive system 4. When the drive system 4 is extended, the left vertex is lifted upward, and when the drive system 4 is retracted, the left vertex moves downward. In production, when the ultra-thin glass flows down at the initial stage of production, the glass ribbon is incomplete because the process parameters and equipment status have not yet reached the best. At this time, the movable support 3 is adjusted by the drive system 4 to make the movable support 3 to the highest position, that is, the left vertex is lifted upward. At this time, the conveyor belt 31 on the movable support 3 does not contact the glass, allowing the glass to flow directly into the broken glass tank below to prevent poorly formed glass from entering the production line. When the glass forming state gradually improves, the movable support 3 is adjusted through the driving system 4, that is, the left vertex moves downward, so that the conveyor belt 31 on the movable support 3 and the glass are connected and matched to a certain extent, and the upper pressure roller 2 gradually matches the preset position of the glass and the movable support 3 as the glass flows, so that the glass maintains a certain angle and contact strength during the conveying process, and the glass has a good steering, which effectively solves the technical problem that the existing steering device cannot accurately and effectively control the conveying state of ultra-thin glass, resulting in a low product yield.

[0031] like Figure 2 As shown, in the technical solution of Example 1, transmission rollers 30 are provided at both ends of the movable support 3, and the two transmission rollers 30 are connected by a conveyor belt 31. The conveyor belt 31 can better assist the glass in conducting, realize fast and efficient transportation, and reduce damage during transportation, and can realize continuous, high-efficiency, and large-angle transportation. Moreover, the use of the conveyor belt 31 can avoid contamination or damage to the material, ensure the quality of the material, and the conveyor belt 31 is safe to operate, easy to use, and easy to maintain. It is particularly noted that the conveyor belt 31 is the best implementation scheme of the present application, but it does not mean that implementation schemes such as conveyor rollers are excluded, and structures equivalent to the above principles should be included in the protection scope of the present application.

[0032] like Figure 2 As shown, in the technical solution of the first embodiment, the shaft 32 of one of the driving rollers 30 is connected to the bracket 1 through a bearing. Since the shaft 32 and the bracket 1 are directly provided with bearings, and since the bracket 1 only supports the shaft 32, there is no driving effect between the two, so the rotation of the shaft 32 will not affect the state change of the movable support 3.

[0033] like Figure 2As shown, in the technical solution of embodiment 1, the rotating shaft 32 is driven by the first servo motor 33. The servo motor can control the speed, and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases at a uniform speed as the torque increases. By using a servo motor, the speed of the conveyor belt 31 can be accurately controlled to meet the needs of the production rhythm. It is particularly noted that the servo motor is the best implementation scheme of this application, but it does not mean that implementation schemes such as stepper motors are excluded. Structures equivalent to the above principles should be included in the protection scope of this application.

[0034] like Figure 1 As shown, in the technical solutions of some embodiments, the upper pressure roller 2 is driven by the second servo motor, or the upper pressure roller 2 is connected to the rotating shaft 32 through a transmission mechanism. When the upper pressure roller 2 is driven by the second servo motor, the rotation speed of the upper pressure roller 2 and the rotation speed of the conveyor belt 31 are synchronized by adjusting the rotation speeds of the first servo motor 33 and the second servo motor respectively. When the upper pressure roller 2 is connected to the rotating shaft 32 through a transmission mechanism, the rotation speed of the upper pressure roller 2 and the rotation speed of the conveyor belt 31 are synchronized by adjusting the speed ratio of the transmission mechanism. The transmission mechanism is a component or mechanism that transfers power from one part of the machine to another part to make the machine or machine parts move or operate. The above transmission mechanism refers to a transmission that uses mechanical means to transfer power and motion. It includes two categories: one is to transmit power and friction transmission by friction between machine parts, and the other is meshing transmission that transmits power or motion by meshing of the active part and the driven part or by meshing of the intermediate part.

[0035] like Figure 3 As shown, in the technical solution of the first embodiment, the driving system 4 includes a connecting shaft 40, a driving member 41, a mounting seat 42 and a fixed base plate 43. The movable end of the driving member 41 is rotatably connected to the movable support 3 through the connecting shaft 40, and the fixed end of the driving member 41 is mounted on the fixed base plate 43 through the mounting seat 42. It is particularly noted that the connecting shaft 40 and the movable support 3 can also be connected through a bearing, that is, the connecting shaft 40 only acts on the movable support 3 to adjust the angle around the rotation point with the bracket 1, and will not rotate with the movable support 3; the mounting seat 42 also adopts a triangular structure in the best embodiment of the present application. Since the triangular structure has stability, it is used as the best implementation scheme of the present application, but it does not mean that implementation schemes such as squares, rectangles and other shapes are excluded. Structures equivalent to the above principles should be included in the protection scope of the present application.

[0036] like Figure 3 As shown, in the technical solution of the first embodiment, the mounting seat 42 is connected to the fixed base plate 43 through a bearing, and the mounting seat 42 can rotate relative to the fixed base plate 43. The mounting seat 42 can rotate relative to the fixed base plate 43 according to the activity requirements of the driving member 41. It is particularly noted that the fixed base plate 43 and the bracket 1 can be connected to the frame to form a whole.

[0037] like Figure 3 As shown, in the technical solution of the first embodiment, the driving member 41 adopts an electric cylinder, and the extension and retraction of the electric cylinder is adjusted by the control system. It is particularly noted that the driving member 41 can also adopt an electric push rod, a precision hydraulic telescopic member, etc., and the push rod control system adjusts the extension and retraction so that the movable support 3 can adjust the angle according to the working conditions.

[0038] like Figure 1 As shown, in the technical solution of embodiment 1, the position of the upper pressing roller 2 can be adjusted relative to the bracket 1. Regarding the setting of the upper pressing roller 2, in the prior art, the upper pressing roller 2 can be set on the frame through a movable shaft and adjusted relative to the bracket 1 according to production needs, which will not be described in detail here.

[0039] like Figure 1 As shown, in the technical solution of the first embodiment, the diameters of the upper pressure roller 2 at both ends are larger than the central diameter. The shape of the upper pressure roller 2 is similar to that of a dumbbell, which can effectively reduce the contact with the glass and avoid defects on the glass surface due to contact. It is particularly noted that the above shapes are not unique, for example, in multi-step design and transitional design, as long as they can meet the above functions, they should be included in the protection scope of this application.

[0040] Usage process:

[0041] In Example 1, the upper pressure roller 2 is mechanically connected to the driving roller 30 of the conveyor belt 31 to move at the same speed. When the ultra-thin glass flows down in the early stage of production, the glass belt is incomplete because the process parameters and equipment status have not yet reached the best. At this time, the control system electrically controls the electric cylinder to advance, so that the movable support 3 reaches the highest position, and the glass flows directly into the broken glass groove below to prevent the poorly formed glass from entering the conveyor belt 31. When the glass forming state gradually improves, the control system electrically controls the electric cylinder to retreat to a certain position, and the servo motor is started to start the conveyor belt 31. When the glass approaches the conveyor belt 31 by a certain distance, the control system electrically links the electric cylinder to push the movable support 3, so that the conveyor belt 31 and the glass are connected and matched to a certain extent. As the glass flows, the position of the upper pressure roller 2 gradually matches the preset position of the glass and the conveyor belt 31, so that the glass maintains a certain angle and contact strength during the conveying process. The two ends of the upper pressure roller 2 contact the edge of the glass, so that the glass maintains a relatively fixed state. The glass not only has a good turn, but also provides a good measurement environment for installing various related measurement sensors near the turn.
