DETAILED DESCRIPTION

[0028] like Figures 1 to 9 As shown, the present invention provides an impurity removal device for manufacturing tempered glass, comprising an inverted L-shaped bracket installed on the outer side wall of the mold 1; the bracket is connected to a turntable 2 near the side wall of the mold 1; the turntable 2 has a plurality of chutes in a circular array with the center of the turntable 2 as the center on the side near the mold 1; each chute is opened along the radial direction of the turntable 2; a first telescopic mechanism 3 is slidably arranged in each chute along the axial direction of the turntable 2; the fixed end of each first telescopic mechanism 3 is slidably connected to the chute, and its telescopic end is connected to a fixed block 4; the first telescopic mechanism 3 can drive the fixed The block 4 moves along the axis of the turntable 2; a fixed groove is provided on the side wall of each fixed block 4 facing the axis of the turntable 2; an extension plate 6 capable of extending out of the fixed groove is slidably provided in the fixed groove through a second telescopic mechanism 5; the extension plate 6 can be driven to extend out of or retract into the fixed groove by the second telescopic mechanism 5; the turntable 2 is also provided with a receiving box 28 for salvaging the softened glass 27 in the mold 1; the receiving box 28 is connected to the turntable 2 through a fixed cylinder 29; a connected return groove is provided on the circumference of the receiving box 28; a stopper 30 is rotatably connected between the opposite side walls of the return groove through a return axis.

[0029] The principle and beneficial effects of the above technical solution:

[0030] Rotate the turntable 2, select two relatively set fixed blocks 4, drive the receiving box 28 into the mold 1 through the fixed cylinder 29, so that the softened glass 27 containing crystal impurities 26 is loaded into the receiving box 28, and lift the receiving box 28 through the fixed cylinder 29, so that the receiving box 28 is away from the mold 1. Wait for a period of time, so that the softened glass 27 is cooled from the glass liquid to a state with a certain viscosity, and drive the fixed block 4 into the receiving box 28 through the first telescopic mechanism 3, so that the protruding plate 6 is located below the impurities, and let the two first telescopic mechanisms 3 slide close to each other, so that the two fixed blocks 4 will block and limit the softened glass 27 containing crystal impurities 26, and then drive the protruding plate 6 to extend from the fixed groove through the second telescopic mechanism 5, so that the two protruding plates 6 are close to each other, so that the two protruding plates 6 separate the softened glass 27 and the crystal impurities 26 (as shown in FIG. Figure 8 As shown); the extended plate 6 is used to separate the crystallized impurities 26 and the softened glass 27 from two directions, and the other two oppositely arranged first telescopic mechanisms 3 are controlled in turn to approach each other from the other direction, so that the surrounding fixed blocks 4 block and limit the softened glass 27 containing the crystallized impurities 26. In the same way, the extended plate 6 around the crystallized impurities 26 is moved toward the crystallized impurities 26, so that the crystallized impurities 26 and the softened glass 27 are completely separated, and then the crystallized impurities 26 on the extended plate 6 are manually removed, and then the stop block 30 is rotated to allow the softened glass 27 that has not yet completed cooling and has a certain viscosity to flow from the return groove into the mold 1.

[0031] By using multiple pairs of first telescopic mechanisms 3 to cooperate with each other, the crystallized impurities 26 and the softened glass 27 are separated from each other from different directions. During the separation process, the protruding plates 6 on the sides of the crystallized impurities 26 gradually squeeze the softened glass 27 in the direction of gradually approaching the crystallized impurities 26. Since the softened glass 27 has surface tension, as the crystallized impurities 26 gradually leave the softened glass 27, less softened glass 27 adheres to the crystallized impurities 26.

[0032] In this embodiment, Figure 4 As shown, a vertical groove 9 is provided on the side wall of the protruding plate 6 close to the mold 1; a first vertical block 8 that can extend out of the vertical groove 9 slides in the vertical groove 9; the vertical groove 9 vertically penetrates both sides of the protruding plate 6; a second vertical block 10 is provided on one side of the first vertical block 8; the second vertical block 10 is slidably set in the vertical groove 9, and the sliding direction is opposite to that of the first vertical block 8; a starting groove 11 is provided on the opposite side walls of the vertical groove 9, which penetrates to both sides of the protruding plate 6; a starting block 12 is provided in the middle of each starting groove 11; the third telescopic mechanism 7 is respectively provided on the opposite side walls of each starting block 12; the fixed ends of the third telescopic mechanism 7 are respectively vertically connected to the corresponding side walls of the starting block 12, and the telescopic ends of the third telescopic mechanism 7 are respectively connected to the first vertical block 8 and the second vertical block 10 through the corresponding transition blocks 13.

[0033] The principle and beneficial effects of the above technical solution:

[0034] Some crystalline impurities 26 on the surface of the softened glass 27 can be solved by the above solution, but some crystalline impurities 26 exist inside the softened glass 27. In order to remove the crystalline impurities 26 inside the softened glass 27, Figure 9 As shown, the receiving box 28 is used to receive the softened glass 27 with crystallized impurities 26 in the same way, and the protruding plate 6 and the crystallized impurities 26 are located at the same horizontal plane by the first telescopic mechanism 3, and then the protruding plate 6 is controlled to approach the crystallized impurities 26 by the second telescopic mechanism 5. At the same time, the first vertical block 8 and the second vertical block 10 are driven to slide in opposite directions by the third telescopic mechanism 7, so that the distance between the first vertical block 8 and the second vertical block 10 becomes larger, and the second telescopic mechanism 5 is cooperated with, when the position of the crystallized impurities 26 is reached, the first vertical block 8 and the second vertical block 10 are moved relative to each other, so as to clamp the crystallized impurities 26, and under the action of the second telescopic mechanism 5, the protruding plate 6 is driven back to the fixed groove to complete the removal of the crystallized impurities 26; then the stopper 30 is rotated to allow the softened glass 27 that has not yet completed cooling and has a certain viscosity to flow from the return groove into the mold 1.

[0035] Typically, the entire section of the crystalline impurity 26 exists in the softened glass 27. By cooperating with the other first telescopic mechanism 3 and the fixed block 4 connected thereto, the fixed block 4 is allowed to approach the softened glass 27 from different directions, so that the first vertical block 8 and the second vertical block 10 in the other protruding plate 6 can cooperate with each other, and the fixed blocks 4 can move relative to each other, thereby pushing the softened glass 27 to flow, thereby adjusting the position of the entire section of the crystalline impurity 26 located in the softened glass 27, so that the entire section of the crystalline impurity 26 is adjusted from an inclined state to a horizontal state, and can be clamped and removed by the first vertical block 8 and the second vertical block 10 at one time, thereby preventing the crystalline impurity 26 from remaining in the softened glass 27.

[0036] In this embodiment, Figure 5 、 6As shown, the opposite side walls of the first vertical block 8 and the second vertical block 10 are provided with cutting grooves 14; two sliding frames 15 are provided in each cutting groove 14 for sliding in the horizontal direction; a fixing bar 16 capable of vertically extending out of the cutting groove 14 is slidably provided in each sliding frame 15 through a fourth telescopic mechanism, and the fixing bar 16 is provided with a swinging groove 17 along its length direction and opened toward the notch of the cutting groove 14; a plurality of swinging rods 18 distributed along the length direction of the fixing bar 16 are installed between the opposite side walls of the fixing bar 16; a rotating cutting disc 19 is coaxially sleeved on each swinging rod 18, and the cutting disc 19 can move along the axial direction of the swinging rod 18; the notch of each cutting groove 14 is provided with a shielding member that allows the cutting disc 19 to extend out of the cutting groove 14 and can clamp the crystalline impurities 26.

[0037] The principle and beneficial effects of the above technical solution:

[0038] When the entire section of crystalline impurities 26 is clamped and taken out by the first vertical block 8 and the second vertical block 10, since the entire section of crystalline impurities 26 is located inside the softened glass 27, a portion of the softened glass 27 will be taken out. In order to reduce the softened glass 27 that is taken out, the first vertical block 8 and the second vertical block 10 are positioned and close to each other. When the impurities are clamped by the two shielding members, a working plane is provided for the cutting of the cutting disk 19. The cutting disk 19 on the swing rod 18 is slid and the position of the cutting disk 19 is adjusted. The fixing bar 16 is driven to move toward the notch of the cutting groove 14 by the fourth telescopic mechanism and extends out of the notch under the action of the shielding member. The plurality of cutting disks 19 rotate, thereby cutting the softened glass 27 with a certain viscosity around the crystalline impurities 26, so that the softened glass 27 around the crystalline impurities is separated from the crystalline impurities. Then, the first vertical block 8 and the second vertical block 10 that clamped the crystalline impurities are driven to leave by the second telescopic mechanism 5. The setting of the cutting disk 19 can prevent excess softened glass 27 from being taken out when the crystalline impurities 26 are taken out.

[0039] like Figure 9 As shown, by sliding the two sliding frames 15, the positions of the two sliding frames 15 can be adjusted so that the cutting disk 19 is positioned outside the entire section of crystalline impurities 26, and a preliminary position adjustment is performed. Then, by sliding the cutting disk 19 on the swing rod 18, the position of the cutting disk 19 is accurately adjusted so that the cutting disk 19 can be as close to the crystalline impurities 26 as possible, and the softened glass 27 is cut by the cutting disk 19, thereby reducing the softened glass 27 with a certain viscosity that is taken away.

[0040] In this embodiment, Figure 6 、 7As shown, several pairs of horizontally arranged through slots 20 are opened between the opposite side walls of the swing groove 17 and penetrate the outer side walls of the fixed bar 16; several pairs of through slots 20 are distributed along the length direction of the fixed bar 16, corresponding to the swing rod 18; one of the through slots 20 in each pair of through slots 20 has a rotating slot perpendicular to the through slot 20 along the length direction perpendicular to the fixed bar 16; a rotating shaft 21 is coaxially connected to the rotating slot; one end of the rotating shaft 21 extends into one of the through slots 20, and one end of the swing rod 18 is perpendicularly connected to the end of the rotating shaft 21 extending into the through slot 20; the other end of the swing rod 18 is located in the other through slot 20 in the same pair of through slots 20, and the rotation of the rotating shaft 21 can drive the swing rod 18 to swing in the same pair of through slots 20.

[0041] The principle and beneficial effects of the above technical solution:

[0042] By driving the swing rod 18 to rotate through the rotating shaft 21, the angle between two adjacent cutting discs 19 can be adjusted so that the cutting disc 19 can better fit the shape of the entire section of crystalline impurities 26 existing in the softened glass 27. Therefore, when cutting the softened glass 27 around the crystalline impurities 26, more softened glass 27 can be left, and more viscous softened glass 27 can be prevented from being taken away.

[0043] In this embodiment, Figure 4 As shown, each shielding member includes a plurality of shielding strips 22 that are horizontally slidably arranged at the notch of the cutting groove 14; the opposite side walls of the cutting groove 14 are correspondingly provided with shielding grooves (not shown in the figure); the two ends of the shielding strips 22 are respectively located in the corresponding shielding grooves; the sliding direction of the shielding strips 22 is the same as the sliding direction of the sliding frame 15, and when the shielding strips 22 slide, a gap can be formed between the shielding strips 22 to allow the cutting disc 19 to extend out.

[0044] The principle and beneficial effects of the above technical solution:

[0045] By sliding the shielding strips 22, gaps can be left between the shielding strips 22, so that the cutting disc 19 can be exposed through the gaps. When the cutting disc 19 cuts the softened glass 27 through the gaps, the other shielding strips 22 that are bonded to each other can form a complete plate shape, thereby better clamping the entire section of crystalline impurities 26.

[0046] In this embodiment, Figure 1As shown, it also includes a slide rail 23 arranged on the outer side wall of the mold 1 along the length direction of the mold 1; the bracket includes a vertical bar 24 slidably arranged on the slide rail 23 and a transverse telescopic mechanism 25 perpendicularly arranged on the end of the vertical bar 24 away from the slide rail 23; the transverse telescopic mechanism 25 is located directly above the mold 1; the fixed end of the transverse telescopic mechanism 25 is vertically connected to the vertical bar 24, and the turntable 2 is rotatably connected to the telescopic end of the transverse telescopic mechanism 25, and the turntable 2 is located between the telescopic end and the mold 1; the transverse telescopic mechanism 25 can drive the turntable 2 to move, so that the turntable 2 moves to the side away from the slide rail 23.

[0047] The principle and beneficial effects of the above technical solution:

[0048] The position of the first telescopic mechanism 3 on the turntable 2 can be adjusted by the sliding bracket and the transverse telescopic mechanism 25 , thereby facilitating the positioning and clamping of the crystallized impurities 26 .

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
