A special glass uniform distribution forming system based on a centrifugal mold

Abstract

The present invention relates to the technical field of glass production, and discloses a special glass uniform distribution forming system based on a centrifugal mold, which includes a chassis. Above the chassis, there is a first mold tray with a plurality of circular through holes pre-opened. Above the first mold tray, there is a telescopic cylinder. A transmission part is jointly arranged on the chassis and the first mold tray, and a centrifugal part is jointly arranged on the first mold tray and the telescopic cylinder. This special glass uniform distribution forming system based on a centrifugal mold can solve the problems in existing glass centrifuges. Most of them use non-closed molds and an open production environment. After the centrifugal mold is heated, the heat dissipates relatively quickly, and the cooling temperature changes too fast, resulting in defects such as uneven heating of the glass melt and cracks. Moreover, when the glass melt is centrifuged while exposed to the air, rotation may cause surface disturbance and entrap a small amount of air to form bubbles. During the high-speed centrifugation process of an open centrifugal mold, it is easy to have problems such as leakage of the glass melt, causing fires or equipment damage.

Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and particularly relates to a special glass uniform distribution forming system based on a centrifugal mold. Background Art

[0002] Special glass is a high-performance glass material made by adjusting the composition of traditional glass or adopting special processes, and has physical properties, optical properties and chemical stability that traditional glass does not have. The application of a centrifugal mold in glass manufacturing is to generate centrifugal force by rotating the mold at high speed, so that the glass melt is evenly distributed on the surface of the mold, and after cooling, a glass product with uniform forming is obtained.

[0003] In this regard, the present application designs a special glass uniform distribution forming system based on a centrifugal mold. Existing glass centrifuges are mainly used for ordinary glass products, and mostly use non-closed molds and open production environments. Since special glass has high requirements for temperature control, the heat of the centrifugal mold dissipates quickly after being heated, and the temperature changes too fast during the cooling process, which will cause internal stress, resulting in defects such as uneven heating of the glass melt and cracks; and the viscosity of special glass in the molten state is significantly higher than that of ordinary glass, so it is necessary to increase the rotation speed to enhance the centrifugal force to evenly fill the mold. During the centrifugation of the glass melt exposed to the air, although the high speed rotation can discharge the bubbles in the glass melt, it will also cause surface disturbance and entrain a small amount of air to form micron-sized bubbles; in addition, during the high-speed centrifugation of an open centrifugal mold, the glass melt is likely to leak, causing fires or equipment damage. Summary of the Invention

[0004] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a special glass uniform distribution forming system based on a centrifugal mold, which can effectively solve the problems that most existing glass centrifuges use non-closed molds and open production environments, the heat of the centrifugal mold dissipates quickly after being heated, and the temperature changes too fast during the cooling process, resulting in defects such as uneven heating of the glass melt and cracks; and when the glass melt is centrifuged in the air, the high speed rotation may cause surface disturbance and entrain a small amount of air to form micron-sized bubbles; in addition, during the high-speed centrifugation of an open centrifugal mold, the glass melt is likely to leak, causing fires or equipment damage.

During this period, as the centrifugal force generated by the rotation of the multiple lower molds and the upper mold increases from small to large, the multiple counterweight plates will gradually extend outward from the outer side of the circular support column, jointly driving the corresponding upper mold to move downward. When the centrifugal force required for the formation of the special glass melt is reached, the multiple counterweight plates will also extend to the maximum distance. At this time, the corresponding upper mold and the corresponding lower mold will gradually change from a semi-open state to a tightly fitting sealed state, avoiding the problem that when the centrifugal force is enhanced at a high speed to uniformly fill the mold, the glass melt is exposed to the air during centrifugation, resulting in air being wrapped on the surface to form bubbles, and avoiding the problems of glass melt leakage causing fires or equipment damage.

An annular plate two 572 is rotatably installed at the upper end of the mold tray two 53 corresponding to the position of the annular plate one 571.

A compression spring is sleeved on the outer wall of the circular support column 54 between the annular plate one 571 and the annular plate two 572. And a plurality of limit chutes evenly distributed in a circumferential manner are formed on the outer wall of the circular support column 54 corresponding to the installation through holes. A weight plate 573 is slidably connected in the limit chutes through a compression spring, and the outer end of the weight plate 573 is movably abutted against the inner wall of the installation through hole.

[0042] The upper and lower ends of the ball screw 42 are smooth shaft sections, and the middle part is a spiral section. An auxiliary tray 45 is arranged on the upper side of the turntable 41 and is movably sleeved on the outer wall of the smooth shaft section of the ball screw 42. The upper end of the auxiliary tray 45 is movably fitted against the lower end face of the mold tray two 53. A compression spring is sleeved on the outer wall of the ball screw 42 between the turntable 41 and the auxiliary tray 45.

[0043] The driving member 44 includes a forward and reverse motor 441 installed in the middle of the machine case 1 through a motor base. The output shaft of the forward and reverse motor 441 rotatably penetrates through the machine case 1 and is fixedly connected to the turntable 41. A support shaft rotatably connected to the turntable 41 is installed on the inner wall of the upper end of the outer cylinder of the telescopic cylinder 3. The outer wall of the support shaft is rotatably fitted against the inner wall of the ball screw 42. The outer walls on the left and right sides of the outer cylinder of the telescopic cylinder 3 are fixedly connected to the machine case 1 through connecting plates.

[0044] The driving member 44 further includes a servo motor 442 installed on the right side of the forward and reverse motor 441 in the chassis 1 through a motor base. The output shaft of the servo motor 442 rotates through the chassis 1 and is fixedly connected with a transmission gear 443. At the position corresponding to the transmission gear 443 on the upper end of the chassis 1, an internal gear ring and an external gear ring are respectively rotatably installed. The external gear ring is fixedly sleeved on the outer wall of the internal gear ring. The transmission gear 443 meshes with the internal gear ring. The lower ends of a plurality of stepped support columns 51 are all fixedly sleeved with driven gears 444, and a plurality of driven gears 444 all mesh with the external gear ring.

[0045] A plurality of avoidance holes evenly distributed in a circumferential manner are formed at the lower end of the outer cylinder of the telescopic cylinder 3. Avoidance holes are also formed at the positions of the left and right two connecting plates on the outer wall of the telescopic cylinder 3 corresponding to the avoidance holes. Automatic blowtorches 6 are installed through the outer wall of the inner cylinder of the telescopic cylinder 3 corresponding to the plurality of avoidance holes.

[0046] During specific implementation:

[0047] In the present application, the inner cylinder of the telescopic cylinder 3 is initially retracted to the upper side and is in an open state. At this time, a plurality of automatic blowtorches 6 are also located at the upper side position. The mold tray two 53 together with a plurality of upper molds 55 are all located at the upper side position. When feeding the glass melt, first, the forward and reverse motor 441 is used to control the turntable 41 to drive the mold tray one 2 to rotate intermittently in the forward direction. The mold tray one 2 drives a plurality of lower molds 52 to rotate intermittently. It should be noted that since the lead screw nut 43 is also located at the upper side and is in a state of being disengaged from the ball screw 42, when the turntable 41 drives the ball screw 42 to rotate forward, it will not restore the screw connection with the lead screw nut 43 to drive the lead screw nut 43 to move. And at this time, the balls in the lead screw nut 43 are blocked by the outer wall of the optical axis section at the upper end of the ball screw 42 and will not be scattered, so as to restore the screw connection with the ball screw 42 subsequently. Then, the external glass melt automatic feeding device sequentially conveys a fixed amount of glass melt into a plurality of lower molds 52.

[0048] When the molten glass is heated, after the feeding of the molten glass is completed in the multiple lower molds 52, the forward and reverse motors 441 are used to control the turntable 41 to rotate in the opposite direction. Under the gravity of the mold tray 2 53 and the multiple upper molds 55, the lead screw nut 43 will resume the spiral connection with the ball screw 42, so as to achieve the effect of controlling the ball screw 42 to drive the mold tray 2 53 to move downward through the lead screw nut 43. At this time, the mold tray 2 53 will drive the inner cylinder of the telescopic cylinder 3 to move downward to a position fitted on the mold tray 1 2, and the multiple upper molds 55 will also move downward with the mold tray 2 53, so that the multiple arc slides 565 Insert it into the corresponding arc-shaped sliding hole to achieve the docking effect of the upper mold 55 and the lower mold 52. During this period, when the screw nut 43 moves downward to the position of the lower optical axis section of the ball screw 42, the auxiliary tray 45 is squeezed to make it move downward synchronously until the screw nut 43 is disengaged from the ball screw 42 again, and as the ball screw 42 continues to rotate in the opposite direction, it will not restore the spiral connection with the screw nut 43 to drive the screw nut 43 to move, and then control multiple automatic flamethrowers 6 to heat the glass melt in the multiple lower molds 52, and keep the temperature of the lower mold 52 and the upper mold 55 at a suitable temperature.

[0049] When the temperatures of the glass melts in multiple lower molds 52 are all appropriate during the centrifugal forming of the glass melt, the servo motor 442 is used to control the rotation of the transmission gear 443. Through the transmission of the transmission gear 443 with the internal gear ring and the external gear ring, multiple driven gears 444 are driven to rotate synchronously. The multiple driven gears 444 drive the corresponding lower molds 52 and upper molds 55 to rotate through the corresponding stepped support columns 51. It should be noted that at this time, the multiple lower molds 52 and upper molds 55 are in a semi-open state. First, the servo motor 442 is used to control the multiple lower molds 52 and upper molds 55 to rotate at a lower speed. When the glass melt is slowly and evenly distributed under the centrifugal force and the gas in the glass melt is discharged, the servo motor 442 is then used to control the multiple lower molds 52 and upper molds 55 to rotate at a high speed to achieve the centrifugal force required for the forming of the special glass melt. During this period, as the centrifugal force generated by the rotation of the multiple lower molds 52 and upper molds 55 increases from small to large, the multiple counterweight plates 573 will gradually extend outward from the outside of the circular support column 54. Under the cooperation of the installation through holes, they will jointly drive the corresponding upper mold 55 to move downward, and through the multiple arc-shaped sliding plates 565, they will jointly squeeze the corresponding annular abutting plate 564 to make it retract into the corresponding receiving chute. When the centrifugal force required for the forming of the special glass melt is reached, at this time, the multiple counterweight plates 573 will also extend to the maximum distance. At this time, the corresponding upper mold 55 will be tightly attached to the corresponding lower mold 52 for sealing. Until the glass melt is gradually formed, the multiple automatic blowtorches 6 can be controlled to stop working first and wait for the formed glass products to be preliminarily cooled. Then, the servo motor 442 is used to control the multiple lower molds 52 and upper molds 55 to gradually reduce the speed and then stop working. It should be noted that when the servo motor 442 controls the multiple lower molds 52 and upper molds 55 to gradually reduce the speed, under the action of the compression spring, the multiple counterweight plates 573 will retract into the corresponding limit chutes, and the circular support column 54 will drive the upper mold 55 to move upward to return to its original position.

[0050] When removing the formed glass products, the turntable 41 needs to be controlled to rotate forward again by the forward and reverse motor 441. Under the action of the compression spring, the auxiliary tray 45 will push the lead screw nut 43 upward, and the auxiliary lead screw nut 43 will be restored to the screw connection with the ball screw 42, so as to achieve the effect of controlling the ball screw 42 to drive the mold tray two 53 upward through the lead screw nut 43. At this time, the multiple upper molds 55 will also move upward to return to their original positions, making the lower molds 52 in an open state for cooling and material taking work. Then, the forward and reverse motor 441 is used to control the turntable 41 to drive the mold tray one 2 to change from continuous forward rotation to intermittent forward rotation. The multiple lower molds 52 will drive the corresponding formed glass products to rotate intermittently forward. Then, the formed glass products are sequentially cooled twice by the external cooling equipment. After they are cooled to room temperature, the multiple formed glass products are sequentially taken out by the external automatic material taking equipment.

[0051] When installing the lower mold 52 and the upper mold 55, the staff rotates the corresponding annular rotating plate 562 by 45 degrees, so that the arc magnets 563 on the annular rotating plate 562 are respectively disengaged from the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54. Under the action of the compression spring, multiple insertion rods 561 will slide towards the inner wall direction of the corresponding annular rotating plate 562. Then, the staff inserts the installation rods 56 on the lower mold 52 or the upper mold 55 into the corresponding installation slots respectively. During this period, the multiple insertion rods 561 are controlled to slide along the guiding chute on the outer wall of the installation rod 56 until the insertion end of the installation rod 56 on the lower mold 52 or the upper mold 55 is closely attached to the inner wall of the corresponding installation slot. Finally, the staff rotates the corresponding annular rotating plate 562 by 45 degrees again, so that the arc magnets 563 on the annular rotating plate 562 are respectively restored to magnetic attraction connection with the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54, and the multiple insertion rods 561 will be respectively inserted into the corresponding circular slots, thus realizing the effect of quickly inserting the lower mold 52 and the upper mold 55. When disassembling, the staff rotates the corresponding annular rotating plate 562 by 45 degrees, so that the arc magnets 563 on the annular rotating plate 562 are respectively disengaged from the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54, and then the lower mold 52 and the upper mold 55 can be directly pulled out.

[0052] In summary, the present application has the following advantages:

[0053] Advantage 1: When heating the glass melt, by controlling the forward and reverse rotation of the turntable 41 through the forward and reverse motor 441, the screw nut 43 can be controlled to disengage from or restore the screw connection with the ball screw 42. During this period, whenever the screw nut 43 moves to the position of the upper or lower optical axis section of the ball screw 42, the screw nut 43 will disengage from the ball screw 42, and as the ball screw 42 continues to rotate forward or backward, it will not restore the screw connection with the screw nut 43 to drive the screw nut 43 to move, so as to freely control the rise or fall of the inner cylinder of the telescopic cylinder 3, and continue to control the mold tray 1 to drive the multiple lower molds 52 to rotate intermittently forward or backward.

[0054] Advantage 2: At the same time, the multiple upper molds 55 can also be controlled to rise or fall following the mold tray 2, so that the multiple arc-shaped sliding plates 565 are inserted into the corresponding arc-shaped sliding holes, thus realizing the effect of controlling the docking or disengagement of the upper mold 55 and the lower mold 52. Then, the multiple automatic blowtorches 6 are controlled to heat the glass melt in the multiple lower molds 52, and in the closed environment of the telescopic cylinder 3, the temperatures of the lower mold 52 and the upper mold 55 are maintained at an appropriate temperature, avoiding the rapid dissipation of heat after the centrifugal mold is heated, resulting in defects such as uneven heating of the glass melt and cracks.

[0055] Advantage 3: When the glass solution is heated, the turntable 41 driven by the forward and reverse motor 441 controls the second mold tray 53 to rotate in the reverse direction. Under the driving action of multiple driven gears 444 and the external tooth ring, multiple lower molds 52 and upper molds 55 will slowly rotate while rotating around the turntable 41. Thus, when multiple subsequent automatic blowtorches 6 heat multiple lower molds 52, upper molds 55, and the glass melt, the effect of improving the uniformity of heat absorption can be achieved.

[0056] Advantage 4: When the glass melt is centrifugally formed, the servo motor 442 controls multiple lower molds 52 and upper molds 55 to rotate at a lower speed. When the glass melt is slowly and evenly distributed under the centrifugal force and the gas in the glass melt is discharged, the servo motor 442 then controls multiple lower molds 52 and upper molds 55 to rotate at a higher speed to achieve the centrifugal force required for the forming of special glass melt. During this period, as the centrifugal force generated by the rotation of multiple lower molds 52 and upper molds 55 increases from small to large, multiple counterweight plates 573 will gradually extend outward from the outside of the circular support column 54. Under the cooperation of the installation through holes, they will jointly drive the corresponding upper mold 55 to move downward, and through multiple arc-shaped sliding plates 565, they will jointly squeeze the corresponding annular contact plate 564 to make it retract into the corresponding accommodation chute. When the centrifugal force required for the forming of special glass melt is reached, at this time, multiple counterweight plates 573 will also extend to the maximum distance, and at this time, the corresponding upper mold 55 will gradually change from a semi-open state to a tightly fitting sealed state with the corresponding lower mold 52. This can avoid the problem that when the centrifugal force is enhanced at a high speed to evenly fill the mold, air may be wrapped on the surface when the glass melt is centrifuged in the air, forming bubbles, and can also avoid the problems of glass melt leakage causing fires or equipment damage.

[0057] Advantage 5: When removing the formed glass product, first control the formed glass product to be preliminarily cooled in the closed environment of the telescopic cylinder 3, and then the forward and reverse motor 441 controls the ball screw 42 to drive the second mold tray 53 to move upward through the screw nut 43. At this time, the inner cylinder of the telescopic cylinder 3 and multiple upper molds 55 will also move upward and return to their original positions, making the lower mold 52 in an open state for secondary cooling and material taking work. At the same time, it can avoid the problem that the rapid temperature change during the cooling process of the lower mold 52 and the upper mold 55 causes internal stress and affects the quality of the glass product.

[0058] Advantage Six: When installing the lower mold 52 and the upper mold 55, rotate the corresponding annular rotating plate 562 by 45 degrees to release the magnetic attraction connection between the arc magnets 563 on the annular rotating plate 562 and the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54. Insert the mounting rods 56 on the lower mold 52 or the upper mold 55 into the corresponding mounting slots respectively. Then rotate the corresponding annular rotating plate 562 by 45 degrees again to restore the magnetic attraction connection between the arc magnets 563 on the annular rotating plate 562 and the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54. Multiple plugging rods 561 will be inserted into the corresponding circular slots respectively. When disassembling, rotate the corresponding annular rotating plate 562 by 45 degrees to release the magnetic attraction connection between the arc magnets 563 on the annular rotating plate 562 and the arc magnets 563 on the corresponding stepped support column 51 or circular support column 54, and then the lower mold 52 and the upper mold 55 can be directly pulled out, thus achieving the effect of rapid loading and unloading of the lower mold 52 and the upper mold 55.
