Description

Technical Field

[0001] This invention belongs to the field of irregular refractory material flipping technology, specifically relating to a device and method for changing the structure of a flipping machine to achieve irregular material flipping. Background Art

[0002] In the substrate glass industry, a large amount of refractory materials are required. These materials have unique properties, including high density, brittleness, large volume, heavy weight, and irregular shape. Processing often requires multiple flipping and clamping operations. Due to the characteristics of the materials, flipping is difficult and requires specialized flipping tools. Especially when flipping irregularly shaped materials, the shift in the center of gravity after flipping often causes them to tilt and fall off. Because the materials are heavy and brittle, this fall can result in breakage and render them unusable.

[0003] The existing turning machine has a circular rotating wheel on each side. When turning irregular materials after leveling them in one state, the length of the slings on both sides of the turning machine changes. At this time, the center of gravity of the material will shift, causing the material to tilt to one end and fall off the sling, resulting in damage to the material. Summary of the Invention

[0004] This invention provides a device and method for changing the structure of a flipping machine to flip irregular materials, in order to solve the technical problem in the prior art that the center of gravity of irregular materials shifts during the flipping process, causing material damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for changing the structure of a flipping machine to achieve the flipping of irregular materials includes a flipping machine, on which circular wheels are provided on the rotating shafts at both ends of the flipping machine, and an elliptical wheel is provided at one end of the flipping machine. Slings are fixed on the elliptical wheel on one side and the circular wheel on the other side, and irregular materials are fixed on the slings.

[0006] The rotating shaft is located on the central axis of the tilting machine, and both elliptical and circular wheels are mounted on the rotating shaft.

[0007] The circular wheel includes a first circular wheel and a second circular wheel. The first circular wheel is fixed on a rotating shaft on one side of the elliptical wheel, and the second circular wheel is fixed on a rotating shaft on the other side.

[0008] Both the elliptical wheel and the second circular wheel have grooves, and the sling is fixed in the grooves of the elliptical wheel and the second circular wheel.

[0009] The groove of the elliptical wheel is connected to the rotating shaft via a connecting key.

[0010] The sling includes a first sling and a second sling. The first sling is placed in the groove of the elliptical wheel, and the second sling is placed in the groove of the second circular wheel.

[0011] The calculation method for the minor axis diameter B of the elliptical wheel is: B=C; the semicircular arc length L on the major axis side of the elliptical wheel is L1+DE; Where C: diameter of the second circular wheel; L1: semi-circular arc length of the first circular wheel; D: length of the second sling occupied by the irregular material; E: length of the first sling occupied by the irregular material.

[0012] The groove depth of the second circular wheel and elliptical wheel is greater than 5mm and less than 10mm, and the groove width is greater than 100mm and less than 160mm.

[0013] A method for flipping irregular materials by modifying the structure of a flipping machine includes the following steps: Step 1: Lay the irregular material horizontally and level it, then tie one end of each of the two straps to both ends of the irregular material. Step 2: Tie the other ends of the two slings from Step 1 to the elliptical wheel on one side and the round wheel on the other side of the tilting machine, respectively; Step 4: The rotation of the turning machine drives the elliptical wheel and the circular wheels on both sides of the turning machine to turn. The turning of the elliptical wheel and the circular wheels drives the irregular material to turn through the sling, turning the irregular material into an upright state.

[0014] Before the flipping machine flips, the major axis of the elliptical wheel is vertical and the minor axis is horizontal. When flipping, the drive motor rotates the rotating shaft 8, and the elliptical wheel rotates 90°. The major axis of the elliptical wheel rotates to a horizontal position, and the minor axis is in the vertical direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a device for flipping irregular materials by modifying the structure of a flipping machine. By adding an elliptical wheel to one end of the machine, which is based on circular wheels at both ends, the center of gravity of the irregular material can be better balanced, reducing offset during the flipping process. This structure can adapt to irregular materials of different shapes and sizes. Simultaneously, the circular wheels at both ends can also flip regular materials, improving the versatility of the equipment.

[0016] Furthermore, the elliptical and circular wheels are mounted on the rotating shaft to ensure that they rotate synchronously, guaranteeing the smoothness and consistency of the flipping process; the design of the central axis makes the entire device more compact, facilitating installation and maintenance.

[0017] Furthermore, the two circular wheels distributed on both sides of the rotating shaft help to distribute the load evenly and reduce imbalance caused by excessive force on one side; the double circular wheel design improves the stability of the entire system and reduces vibration and shaking during the flipping process.

[0018] Furthermore, the groove design on the round and oval wheels can effectively secure the slings, preventing them from slipping during the flipping process and ensuring safety; the grooves also serve as guides, keeping the slings on the correct path during flipping and preventing tangling or misalignment.

[0019] Furthermore, the groove of the elliptical wheel is connected to the rotating shaft by a connecting key. The connecting key increases the connection strength between the groove and the rotating shaft, ensuring stable operation even under high loads. The connecting key design makes the connection between the elliptical wheel and the rotating shaft easier to disassemble and maintain.

[0020] Furthermore, the two straps are fixed to elliptical and circular wheels respectively, allowing for independent adjustment based on different parts of the material to better balance the center of gravity; this design provides greater flexibility and is suitable for irregular materials of different shapes and sizes.

[0021] Furthermore, by precisely calculating the dimensions of the elliptical wheel, it is ensured that it can compensate for changes in the sling length during the flipping process and maintain the balance of the material. This calculation method optimizes the design of the elliptical wheel, making it more suitable for actual use and improving the stability and safety of the flipping process.

[0022] Furthermore, the grooves on the elliptical and circular wheels are designed to accommodate a variety of straps of different widths and thicknesses, improving the device's versatility; the appropriate groove depth and width ensure that the straps will not easily slip out during flipping, enhancing the fixing effect.

[0023] Furthermore, this invention discloses a method for changing the structure of a flipping machine to achieve the flipping of irregular materials. This method is simple to operate, has clear steps, and is easy to implement. Through reasonable binding and flipping steps, it ensures the safety and reliability of the flipping process and is applicable to a variety of irregular materials, thus having wide applicability.

[0024] Furthermore, by rotating the elliptical wheel, the length of the sling is dynamically adjusted to ensure that the center of gravity of the material remains in a balanced state during the flipping process. This rotation method can effectively reduce the shift of the center of gravity of the material during the flipping process and avoid material damage. Dynamic adjustment makes the flipping process more stable and efficient, improving work efficiency. Attached Figure Description

[0027] To further understand the content of this invention, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 , Figure 2 and Figure 3 A rotating shaft 8 is located on the central axis of the turning machine 7. An elliptical wheel 5 is mounted on one end of the rotating shaft 8. A first circular wheel 4 and a second circular wheel 6 are mounted on opposite ends of the rotating shaft 8. The first circular wheel 4 and the second circular wheel 6 are identical. All three wheels—elliptical wheel 5, first circular wheel 4, and second circular wheel 6—have grooves. The groove of the elliptical wheel 5 is connected to the rotating shaft 8 via a connecting key 9. One end of a first sling 2 is tied to the small end face of the irregular material 1, and one end of a second sling 3 is tied to the large end face of the irregular material 1. The other end of the first sling 2 is connected to the groove of the elliptical wheel 5, and the other end of the second sling 3 is connected to the groove of the second circular wheel 6. The minor axis diameter of the elliptical wheel 5 is the same as the diameter of the first circular wheel 4.

[0030] This embodiment provides a device and method for changing the structure of a flipping machine to achieve the flipping of irregular materials. The specific implementation method is as follows: First, the structure of the flipping machine 7 needs to be modified. A rotating shaft 8 is set on the axis of the flipping machine 7. An elliptical wheel 5 is set on the rotating shaft 8 at one end of the flipping machine 7. Then, a first circular wheel 4 and a second circular wheel 6 are fixed at both ends of the flipping machine, so that one side of the flipping machine 7 has a first circular wheel 4 with an elliptical wheel 5, and the other side of the flipping machine 7 has a second circular wheel 6. Grooves are provided on the elliptical wheel 5, the first circular wheel 4 and the second circular wheel 6. The groove of the elliptical wheel 5 is connected to the rotating shaft 8 through a connecting key 9. The groove depth is greater than 5mm and less than 10mm, and the groove width is greater than 100mm and less than 160mm. Elliptical wheel 5 has a major axis A and a minor axis B, such as Figure 5As shown, when making the elliptical wheel 5, the arc length L of the major axis A of the elliptical wheel should be equal to the semi-arc length L1 of the circular wheel plus the length D of the second sling 3 occupied by the irregular material 1 minus the length E of the first sling 2 occupied by the irregular material 1, that is, L = L1 + DE. When flipping irregular material 1, the following steps are included: Step 1: Level the irregular material 1 in a horizontal position. Irregular material 1 has a large end face and a small end face, and the width of the large end face is greater than the width of the small end face. Tie one end of the first sling 2 to the small end face of the irregular material 1, and tie one end of the second sling 3 to the large end face of the irregular material 1, as follows. Figure 1 and Figure 2 As shown, the length of the second sling 3 occupied by the large end face of the irregular material 1 is greater than the length of the first sling 2 occupied by the small end face; Step 2: Place the other end of the second sling 3 into the groove of the second circular wheel 6 on one side of the flipping machine 7, and place the other end of the first sling 2 into the groove of the elliptical wheel 5 on the other side of the flipping machine 7; the groove depth of the elliptical wheel 5 and the second circular wheel 6 is greater than 5mm and less than 10mm, and the groove width is greater than 100mm and less than 160mm. Step 3: With the irregular material 1 in a horizontal position, adjust its balance and then flip it over. Drive the motor to rotate the rotating shaft 8. The rotating shaft 8 drives the elliptical wheel 5 and the second circular wheel 6 to rotate. The elliptical wheel 5 and the second circular wheel 6 rotate 90°. The major axis of the elliptical wheel 5 rotates from the vertical direction to the horizontal direction, and the minor axis of the elliptical wheel 5 rotates from the horizontal direction to the vertical direction. The state when the flip is successful is as follows. Figure 2 As shown, complete the flipping of irregular material 1.

[0031] During the aforementioned flipping process, the length occupied by both ends of the irregular material 1 in the first strap 2 is less than that in the second strap 3. However, since the arc length on the major axis side of the elliptical wheel 5 is equal to the half-arc length of the circular wheel plus the length D occupied by the irregular material 1 in the second strap 3 minus the length E occupied by the irregular material 1 in the first strap 2, when the major axis of the elliptical wheel 5 is flipped to the horizontal direction, the contact surface between the first strap 2 and the irregular material 1 is compensated by the flipping of the major axis of the elliptical wheel 5. After the flipping, the lengths occupied by the two ends of the irregular material 1 in the first strap 2 and the second strap 3 are the same. Figure 1 and Figure 2 As shown, this avoids the center of gravity shifting due to changes in the slings during the material flipping process, thus preventing the risk of material tilting and falling off.

[0032] More preferably, there are a first circular wheel 4 and a second circular wheel 6 at both ends of the flipping machine 7. The first circular wheel 4 is also provided with a groove. When flipping regular materials, the first sling 2 and the second sling 3 can be placed in the grooves of the first circular wheel 4 and the second circular wheel 6 respectively. By driving the rotating shaft 8 to rotate, the two circular wheels will be driven to rotate. The circular wheels will drive the material to flip through the slings.
