Description

Technical Field

[0001] This invention relates to the field of glass molding equipment technology, and more specifically, to a glass softening and molding equipment. Background Technology

[0002] In the field of glass molding, traditional softening molding equipment usually uses a high-temperature oven to heat and soften the glass block, and then rolls the softened glass block into the desired shape (such as a column) through a roll forming structure. In the existing technology, in order to ensure that the glass remains in a softened state during the roll forming process, it is usually necessary to provide auxiliary heating for the roll forming components. The conventional practice is to set up a gas heating device below the roll forming structure, and use the open flame generated by igniting natural gas to directly heat the roll forming components (such as rollers) above.

[0003] However, this heating method has significant drawbacks. First, because the flame tongue continuously flickers, the tail flame unevenly heats different points on the roll forming piece, resulting in uneven temperature distribution across the roll forming surface. This makes it difficult for the glass block to achieve uniform heating when in contact with these surfaces. Second, the tail flame directly contacts the glass block surface during heating, causing localized thermal stress concentration. During subsequent roll forming, some areas are difficult to deform, leading to pits and dents on the finished product surface. Furthermore, the accumulated stress can cause cracks in the glass block after roll forming, severely impacting the quality of the finished glass product.

[0004] Furthermore, during the aforementioned roll forming process, the glass block gradually decreases in diameter and increases in length to form a columnar shape. However, the extension of the glass block towards both ends is often inconsistent (due to uneven stress on different parts during roll forming), resulting in poor length consistency in the finished columnar glass product. Simultaneously, the shapes of the glass ends cannot be fixed after deformation, leading to irregularities at both ends of the formed columnar glass product, affecting the quality of the glass molding and typically requiring subsequent cutting and polishing. In existing technologies, to address this issue, workers typically use hand-held pressure rollers inserted into the roll forming space to manually squeeze both ends of the glass block to maintain length consistency and end regularity. However, this manual operation method struggles to guarantee length accuracy, and the high-temperature environment at the roll forming structure severely impacts the worker's efficiency, making long-term stable operation impossible. Summary of the Invention

[0005] The purpose of this application is to provide a glass softening and shaping device that solves the technical problems of low heat transfer efficiency, easy scaling, unstable energy efficiency and poor waste heat recovery in traditional heating furnaces.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0007] A glass softening and molding device is installed at the discharge port of a high-temperature oven, which is connected to multiple sets of roller pressing structures via guide slides.

[0008] The multiple sets of roller pressing structures include a bottom roller pressing structure, a top roller pressing structure, and a side roller pressing structure.

[0009] The bottom roller pressing structure includes a bottom roller shaft, both ends of which are rotatably mounted on a support frame. The support frame is connected to a high-temperature oven, and one end of the bottom roller shaft is coaxially and fixedly connected to a rotation drive component.

[0010] The top roller pressing structure includes a top roller shaft, which is connected to the driving end of a displacement driving component, and the displacement direction of the displacement driving component is vertical.

[0011] The side roller pressing structure includes a driven roller shaft, with both ends of the driven roller shaft slidably mounted on the support frame. One end of the driven roller shaft is rotatably connected to the driving end of the displacement driving component two, and the displacement direction of the displacement driving component two is consistent with the guiding direction of the guide slide plate.

[0012] Each of the driven roller, bottom roller, and top roller is equipped with an electric heating element, which is electrically connected to an external power switch.

[0013] The lateral rolling structure also has a molding structure on the side away from the guide slide.

[0014] The plastic structure includes crossbars.

[0015] Two sliders are slidably mounted on the crossbar. Each slider is rotatably connected to one end of a clamping rod. The other end of the clamping rod passes through the gap between the top roller and the driven roller.

[0016] A torsion spring is fixedly sleeved between the rotational connection point of the clamping rod and the slider, and the clamping rod elastically contacts the roller surface of the driven roller shaft.

[0017] Each slider is fixedly connected to the displacement end of a displacement drive component three at its lower part. The displacement drive component is laterally fixed to the displacement end of the displacement component, and the sliding direction of the slider is consistent with the length direction of the crossbar.

[0018] The two ends of the crossbar are respectively fixed to the displacement ends of two displacement components, which are fixed on the support frame. The displacement direction of the displacement components is vertical.

[0019] The end of the clamping rod near the driven roller shaft has a planar cross-section.

[0020] A limit block is fixedly installed at the center of the crossbar, and two sliders are respectively installed on both sides of the limit block.

[0021] Contact sensors are fixed on both sides of the limiting block, and the sensing ends of the contact sensors face the two ends of the crossbar length.

[0022] The contact sensor is electrically connected to the external alarm light.

[0023] The driven roller is located on the side of the bottom roller away from the guide slide, and the top roller is located above the bottom roller.

[0024] When the glass block is in a high-temperature oven or when the glass block is being rolled, the gap width between the driven roller, the bottom roller, and the top roller is less than the width of the glass block.

[0025] The driven roller, bottom roller, and top roller are made of heat-conducting metal, and the roller surfaces of the three rollers are smooth.

[0026] One end of the top roller is rotatably mounted on one end of the transmission plate, the middle part of the transmission plate is rotatably mounted on the support frame, and the other end of the transmission plate is rotatably connected to one end of the hinge plate. The other end of the hinge plate is hinged to the driving end of the displacement driving component one. The displacement driving component one is fixed on the support frame, and the displacement direction of the displacement driving component one is vertical.

[0027] The displacement driving component is configured as a cylinder.

[0028] The technical solution of this application has at least the following advantages and beneficial effects:

[0029] To address the defects of pits and cracks on the surface of finished glass products caused by open-flame heating of rollers in existing glass molding processes, this invention replaces traditional open-flame heating by installing electric heating elements (such as electric heating copper rods) inside the bottom roller, top roller, and driven roller. The electric heating elements can directly and uniformly heat the rollers, reducing uneven roller surface temperature caused by flame movement and minimizing localized thermal stress concentration on the glass block surface.

[0030] This invention, through a molding structure comprising a clamping rod, sliders, a displacement drive component, and a crossbar, enables automatic clamping and compression of the softened glass block at both ends during the rolling process. This structure precisely maintains the distance between the two sliders via the displacement drive component, thereby improving the length accuracy of the finished cylindrical glass product; the end of the clamping rod near the driven roller shaft is designed with a planar cross-section, maintaining a flat end-face compression effect.

[0042] Example

[0043] Please refer to Figures 1-8 This embodiment provides a glass softening and shaping device, which is installed at the discharge port of a high-temperature oven 1. It is used to stabilize and shape the softened glass and maintain the shaping effect. It includes multiple sets of roller pressing structures, which are connected to the high-temperature oven 1 through guide slides 3. The roller pressing structures are used to feed the softened glass in the high-temperature oven 1 into the multiple sets of roller pressing structures for roller pressing and shaping. The multiple sets of roller pressing structures include a bottom roller pressing structure 4, a top roller pressing structure 5, and a side roller pressing structure, which simultaneously roll the three contact surfaces of the glass block 2, rolling the softened glass block 2 into a cylindrical glass product.

[0044] Please refer to Figure 2 and Figure 8A heating base 11 is fixedly installed inside the high-temperature oven 1. A glass block 2 to be softened is placed on the heating base 11. A pushing structure 12 is also installed on the heating base 11, with the pushing direction facing the discharge port of the high-temperature oven 1. The heating structure inside the high-temperature oven 1 softens the glass. A layer of flexible heat insulation cloth 13 is fixed to the edge of the discharge port of the high-temperature oven 1 to reduce the speed at which the high temperature inside the high-temperature oven 1 dissipates to the outside and protects the safe operation of external equipment. The guide slide plate 3 is inclined. The top of the inclined plate is fixedly connected to the discharge port of the high-temperature oven 1, and the bottom of the inclined plate extends to the space between the three roller pressing structures. After the glass is softened, the pushing structure 12 pushes the glass out and guides it through the guide slide plate 3 into the space between the three roller pressing structures, where it contacts the roller pressing surface for roller pressing. The high-temperature drying oven is a common heating device in glass molding, so the specific structure and principle of the device are not described in detail in this manual.

[0045] In traditional glass molding equipment, when using a roller pressing structure for rolling, it is necessary to heat each rolling component (such as the roller shaft) to maintain the softened state of the glass during the rolling process. Currently, gas heating equipment is generally installed below the rolling structure. Natural gas is ignited to generate an open flame, which directly heats the rolling components above. However, because the flame tongue is constantly flickering, the tail flame heats different rolling points on the rolling surface of the rolling components, resulting in uneven temperature rise at various locations. When the glass block 2 comes into contact with these rolling surfaces, it is difficult to heat them evenly. Moreover, the tail flame also directly contacts the surface of the glass block 2, causing localized thermal stress concentration. During the rolling molding process, some areas are difficult to deform, making the finished product prone to pits and dents. Furthermore, with the accumulation of stress, the glass block 2 is also prone to cracks after rolling, affecting the quality of the finished glass product.

[0046] To solve the above problems, please refer to Figures 2-6 In this embodiment, electric heating elements 7 are provided inside the bottom rolling structure 4, the top rolling structure 5 and the side rolling structure to directly heat the rolling parts internally, reducing the occurrence of uneven heating when using open flame heating.

[0047] The bottom roller pressing structure 4 includes a bottom roller shaft 41, a support frame 42, and a rotation drive component 43.

[0048] The top roller pressing structure 5 includes a top roller 51, a transmission plate 52, a hinge plate 53, and a displacement driving component 54.

[0049] The side roll forming structure includes a driven roller shaft 61 and a displacement drive component 62.

[0050] Specifically, the bottom roller 41 is rotatably mounted on the support frame 42 at both ends. The support frame 42 is fixedly connected to the high-temperature oven 1. One end of the bottom roller 41 is coaxially fixedly connected to the rotation drive component 43. The rotation drive component 43 is a motor and is fixed on the support frame 42. The rotation drive component 43 can drive the bottom roller 41 to rotate.

[0051] Specifically, one end of the top roller 51 is rotatably mounted on one end of the transmission plate 52, the middle part of the transmission plate 52 is rotatably mounted on the support frame 42, and the other end of the transmission plate 52 is rotatably connected to one end of the hinge plate 53. The other end of the hinge plate 53 is hinged to the driving end of the displacement driving component 54. The displacement driving component 54 is fixed on the support frame 42, and the displacement direction is vertical. The displacement driving component 54 is set as a cylinder. The displacement driving component 54 can drive the transmission plate 52 to rotate around its own middle axis, so that the top roller 51 at one end of the transmission plate 52 can move up and down.

[0052] Specifically, the driven roller shaft 61 is slidably mounted on the support frame 42 at both ends, with the sliding direction along the guiding direction of the guide slide plate 3. One end of the driven roller shaft 61 is rotatably connected to the driving end of the displacement drive component 62, so that the driven roller shaft 61 can rotate freely under external force. The displacement drive component 62 is fixed on the support frame 42, with the displacement direction along the guiding direction of the guide slide plate 3. The displacement drive component 62 is set as a cylinder, which can drive the driven roller shaft 61 to move closer to or away from the bottom roller shaft 41.

[0053] Preferably, the driven roller 61 is located on the side of the bottom roller 41 away from the guide slide plate 3, and the top roller 51 is located above the bottom roller 41.

[0054] When the glass block 2 is still being heated in the high-temperature oven 1 and has not been pushed out, the rotation drive 43, displacement drive one 54, and displacement drive two 62 are not working, and the gap width between the driven roller 61, the bottom roller 41, and the top roller 51 is less than the width of the glass block 2.

[0055] When the push structure pushes out the glass block 2, the displacement drive component 54 also moves down synchronously, driving the top roller 51 to move up, increasing the gap width between the top roller 51 and the bottom roller 41, so that the softened glass block 2 can pass through the gap and enter between the bottom roller 41 and the driven roller 61. Then, after a certain period of time, the displacement drive component 54 automatically resets, the top roller 51 resets, the gap width between the top roller 51 and the bottom roller 41 is reduced, and it contacts the surface of the glass block 2, so that the three rollers synchronously clamp the glass block 2.

[0056] Specifically, the driven roller 61, bottom roller 41, and top roller 51 are hollow inside, and each of them is fixedly equipped with an electric heating element 7. The electric heating element 7 is an electric heating copper rod, which is easy to match with the cylindrical roller. The electric heating element 7 is electrically connected to an external power switch. When the glass block 2 is clamped by the three rollers, the power is turned on and the electric heating element 7 starts to heat up, so that the surface of the three rollers begins to heat up evenly, maintaining the softening temperature of the clamped glass block 2.

[0057] Preferably, when the electric heating element 7 heats, the rotation drive 43 is activated, driving the bottom roller 41 to rotate. The bottom roller 41 drives the glass block 2 to rotate, while the top roller 51 and the driven roller 61, which apply clamping force to the glass block 2, also rotate under the action of frictional resistance, synchronously rolling the surface of the glass block 2. Under the rolling pressure, the sharp edges of the surface of the glass block 2, which has softened at high temperature, are gradually squeezed and rounded, and gradually become columnar. During this process, the driving end of the displacement drive 54 is always in a vertically extended state. At this time, the top roller 51 is always under the pushing action of the displacement drive 54 (the cylinder pushes pneumatically, so the displacement end has a certain pneumatic elasticity). When the diameter of the glass block 2 gradually shrinks and forms a long columnar shape during the rolling process, the top roller 51 will also be synchronously displaced under the elastic air pressure thrust of the displacement drive 54, so that the roller surface of the top roller 51 can always contact the surface of the glass block 2, thereby realizing the processing of the glass column formed product.

[0058] Preferably, after the glass is rolled (i.e. after the rolling time is fixed), the displacement drive component 62 is activated, driving the driven roller 61 to move away from the bottom roller 41, increasing the gap width between the driven roller 61 and the bottom roller 41, so that the formed columnar glass leaks out through the gap and leaves the rolling position of the three rollers. Below the bottom roller 41, there is also a discharge trough 31, which is fixed on the support frame 42 and is used to collect the finished columnar glass. After the columnar glass leaks out, the displacement drive component 62 is reset, driving the driven roller 61 to reset, and then the rotation drive component 43 stops working, completing the entire processing process.

[0059] It is worth noting that in some feasible embodiments, for some harder glass materials (lower softening degree), the top roller 51 and the driven roller 61 can also be connected to the rotation drive 43 separately, so that all three rollers have rolling force. Specifically, one end of the top roller 51 is coaxially fixedly connected to the drive end of the rotation drive 43, and the rotation drive 43 is fixed on the transmission plate 52. One end of the driven roller 61 is coaxially fixedly connected to the drive of the rotation drive 43, and the rotation drive 43 is fixed to the drive end of the displacement drive 62.

[0060] Although the softened glass block 2 can be rolled into shape using the three roller pressing structures mentioned above, in the actual processing, the diameter of the glass block 2 gradually decreases and its length gradually increases to form a column. However, the length of the glass block 2 extending towards both ends is inconsistent (due to inconsistent force on different parts during rolling), which easily leads to inconsistent lengths of each formed columnar glass product. Moreover, after the ends of the glass block 2 are deformed, the shape of the ends cannot be fixed, resulting in irregular ends of the formed columnar glass product, which affects the molding quality of the glass and requires subsequent cutting and grinding by personnel.

[0061] In traditional molding processes, additional workers are usually stationed outside the roll forming structure. As the softened glass block 2 is gradually rolled into a cylindrical shape, the workers hold two pressure rollers and insert them into both ends of the glass block 2 in the roll forming space to manually squeeze both ends of the glass block 2. This is done to maintain the consistent length of the cylindrical glass product and to keep the two ends of the cylindrical glass product neat. However, manual squeezing makes it difficult to maintain the length accuracy of the cylindrical glass product, and the high temperature at the roll forming structure also affects the processing efficiency of the workers, making it impossible for them to work for long periods of time.

[0062] To solve the above problems, please refer to Figures 1-8 In this embodiment, a molding structure 8 is also provided on the side of the lateral rolling structure 6 away from the guide slide plate 3, which can automatically squeeze the two ends of the softened glass block 2 in the rolling process to maintain the length accuracy and the regularity of the two ends of the columnar glass product.

[0063] The molding structure 8 includes a clamping rod 81, a slider 82, a torsion spring 83, a displacement drive component, a crossbar 85, a cut surface 86, a limiting block 87, and a contact sensor 88.

[0064] Specifically, the two ends of the crossbar 85 are fixed to the displacement ends of two displacement members 9, which are fixed to the support frame 42. The displacement direction of the displacement members 9 is vertical. Two sliders 82 are slidably arranged on the crossbar 85. One end of the clamping rod 81 is rotatably connected to the upper part of each slider 82. The other end of the clamping rod 81 passes through the gap between the top roller shaft 51 and the driven roller shaft 61 and extends into the rolling space. A torsion spring 83 is also fixedly sleeved between the rotational connection point of the clamping rod 81 and the slider 82, so that the clamping... The rod 81 is subjected to the torsion force of the torsion spring 83, thereby elastically contacting the roller surface of the driven roller 61. The driven roller 61 is used to limit the insertion position of the clamping rod 81, preventing the clamping rod 81 from touching the movable top roller 51 and interfering with the movement of the top roller 51. Each slider 82 is fixedly connected to the displacement end of a displacement drive component 84 at its lower part. The displacement drive component is laterally fixed to the displacement end of the displacement component 9. The slider 82 can slide laterally along the crossbar 85 through the displacement drive component 84.

[0065] Preferably, the two sliders 82 on the crossbar 85 can be displaced laterally, allowing the two clamping rods 81 to slide towards each other, forming a clamping effect. When the glass block 2 is not being shaped, the two sliders 82 are located near the two ends of the crossbar 85, away from the center of the crossbar 85, to avoid the clamping rods 81 interfering with the entry of the glass block 2 at the driven roller shaft 61. When the glass block 2 is being rolled, the two sliders 82 move towards each other through the displacement drive member 3 84, gradually approaching the center of the crossbar 85, and extruding and shaping the two ends of the glass block 2 during rolling. The distance between the two sliders 82 can be maintained by the displacement of the displacement drive member 3 84 to maintain the clamping distance accuracy, thereby maintaining the length accuracy and the regularity of the two ends of the columnar glass product.

[0066] It is worth noting that the end of the clamping rod 81 near the driven roller shaft 61 is set as a planar cut surface 86, so that the surfaces of the clamping rod 81 in contact with the two ends of the columnar glass product are flat, maintaining a flat effect.

[0067] It is worth noting that all three rollers are made of heat-conducting metal, which facilitates heat conduction and temperature rise, and maintains the smoothness of the roller surface, which facilitates the shaping of the glass block 2 and the smooth sliding of the clamping rod 81 on its roller surface.

[0068] Preferably, a limit block 87 is fixedly installed at the center of the crossbar 85, and two sliders 82 are respectively installed on both sides of the limit block 87 and slide respectively. Contact sensors 88 are fixed on both sides of the limit block 87. The sensing ends of the contact sensors 88 face the two ends of the length of the crossbar 85. When the displacement drive 84 drives the slider 82 to move, and there is no glass block 2 between the three rollers due to a processing fault (such as material leakage), without the obstruction of the two ends of the glass block 2, the displacement drive 84 will continue to move towards the center of the crossbar 85 until it touches the contact sensor 88. The contact sensor 88 is electrically connected to an external alarm light. When the contact sensor 88 receives the touch signal, it will send an electrical signal to trigger the alarm light to remind the staff that there is no glass block 2 between the three rollers.

[0069] Preferably, the displacement element 9 is set as an electric cylinder. In the actual processing, in order to match softened glass blocks 2 of different diameters, the distance between the top roller 51 and the bottom roller 41 will also change synchronously so as to fit the glass block 2. At this time, the insertion angle of the clamping rod 81 inserted between the three rollers may interfere with the top roller 51 with different spacing. Therefore, by activating the displacement element 9, the entire crossbar 85 is moved vertically upward, so that the clamping rod 81 swings with the contact point of the driven roller 61 as the fulcrum, so that the insertion end of the clamping rod 81 swings down, reducing the contact probability between the insertion end of the clamping rod 81 and the top roller 51 with reduced spacing above, and maintaining the normal operation of each roller pressing structure.

[0070] The various embodiments of the present invention have now been described in detail. To avoid obscuring the concept of the invention, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solutions of this invention based on the above description, and the scope of the invention is defined by the appended claims.
