Description

Technical Field

[0001] This invention relates to the field of glass shearing and forming technology, and more specifically, to a glass shearing and extrusion forming apparatus. Background Technology

[0002] When manufacturing glass products using a molding machine, a stream of molten glass flows downwards from the feeder guide in the front furnace area of ​​the glass furnace, heading towards the working area of ​​the molding machine. The glass stream is sheared into a series of separate glass globules by a shearing device located between the feeder guide and the working area of ​​the molding machine. After the glass globules fall into a pre-set mold, they are then extruded to obtain the corresponding glass product.

[0003] In order to ensure sufficient material, existing glass manufacturing machines usually add more molten glass to the forming mold when producing glass products. However, in this case, there is usually a portion of glass left over at the top of the mold, which means that the glass products need more time for further processing. Summary of the Invention

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0044] Example:

[0045] See Figures 1 to 10 This invention discloses a glass shearing and extrusion forming apparatus, comprising a worktable 100, a support 200, a control panel 300, a forming disc 400, a molten glass shearing structure 500, an extrusion forming structure 600, a chipping structure 700, and a discharge structure 800. The forming disc 400 and the control panel 300 are both mounted on the support 200, and the forming disc 400 is rotatable. A ring of forming holes 410 is provided on the forming disc 400, and a notch 310 is provided at a corresponding position on the control panel 300. The molten glass shearing structure 500 is used to shear the molten glass, the extrusion forming structure 600 is used to extrude and form the molten glass within the forming holes 410, the chipping structure 700 is used to chip excess glass, and the discharge structure 800 is used to remove the pre-formed blank from the forming hole 410 corresponding to the notch 310.

[0046] The glass shearing and extrusion forming apparatus disclosed in this embodiment has a chipping structure 700 in front of the unloading structure 800. When the glass product is still fixed in the forming hole 410, the protruding part of the glass product can be directly cut to obtain a blank that is closer to the product, thereby reducing the difficulty and time of subsequent processing.

[0047] See Figures 1 to 5A bracket 200 is installed on the top of the workbench 100, and the bracket 200 is located in the middle of the workbench 100. A control panel 300 is installed on the bracket 200, and the control panel 300 is fixedly connected to the bracket 200. A notch 310 and a slide 320 are provided on the control panel 300. The slide 320 is located on the top surface of the control panel 300, and the slide 320 is annular along the circumference of the control panel 300. The notch 310 penetrates the control panel 300 along its height direction, and the control panel 300 communicates with the slide 320.

[0048] The forming disc 400 is also mounted on the bracket 200, and the forming disc 400 is rotatably connected to the bracket 200. The forming disc 400 is located above the control disc 300. Multiple forming holes 410 are provided on the forming disc 400, spaced apart circumferentially. Rotating the forming disc 400 causes each forming hole 410 to pass sequentially through a notch 310. When a forming hole 410 passes through a notch 310, the corresponding forming hole 410 connects with the notch 310. At this time, the glass product inside the forming hole 410 can be discharged from the notch 310.

[0049] The glass melt shearing structure 500, extrusion molding structure 600, chip cutting structure 700 and unloading structure 800 are all installed on the worktable 100, and the glass melt shearing structure 500, extrusion molding structure 600, chip cutting structure 700 and unloading structure 800 are arranged sequentially around the forming disk 400, wherein the position of the unloading structure 800 corresponds to the position of the notch 310.

[0050] See Figure 6 The molten glass shearing structure 500 includes a first support platform 510, a funnel 520, and a shearing assembly 530. The first support platform 510 is mounted on the worktable 100. The funnel 520 and the shearing assembly 530 are both mounted on the side of the first support platform 510 facing the forming plate 400. The funnel 520 is located above the forming plate 400, and the bottom of the funnel 520 is close to the forming hole 410 on the forming plate 400. When the forming plate 400 rotates, the forming hole 410 on the forming plate 400 passes under the funnel 520 in sequence. The shearing assembly 530 is located above the funnel 520. A molten glass container (not shown in the figure) is also provided above the shearing assembly 530. The bottom of the molten glass container is provided with an outlet, through which the molten glass can flow out. Since all liquids have surface tension, and the glass liquid has a high density and high surface tension, the glass liquid will slowly condense at the outlet and will not fall immediately. When the glass liquid container condenses to a large enough size at the outlet, the glass liquid is cut off by the shearing component 530. At this time, the cut glass liquid can fall into the forming hole 410 along the funnel 520.

[0051] See Figure 7The extrusion molding structure 600 includes a second support platform 610 and an extrusion block 620. The second support platform 610 is mounted on the worktable 100, and the extrusion block 620 is mounted on the side of the second support platform 610 facing the molding disc 400, and the extrusion block 620 is slidably engaged with the second support platform 610. The extrusion block 620 can move along the height direction of the second support platform 610. When the extrusion block 620 moves downward, it can move to the corresponding molding hole 410, and extrude the molten glass in the molding hole 410 by extruding the molten glass, so that the temporarily softened molten glass fills all the gaps in the molding hole 410, thereby shaping the molten glass into the shape of the molding hole 410.

[0052] See Figure 8 The chip-cutting structure 700 includes a third support platform 710 and a chip-cutting blade 720. The third support platform 710 is mounted on the worktable 100, and the chip-cutting blade 720 is mounted on the side of the third support platform 710 facing the forming disk 400. The chip-cutting blade 720 is slidably engaged with the third support platform 710, and the chip-cutting blade 720 can move radially relative to the third support platform 710 along the forming disk 400. As the molten glass rotates with the forming disk 400, the molten glass gradually cools and solidifies. (See reference...) Figure 1 When the forming disc 400 rotates clockwise, the molten glass will have enough cooling time. Therefore, when the molten glass reaches the chip structure 700 along with the forming hole 410, it has basically solidified. At this time, the chip cutter 720 can be moved to cut off the part of the glass product exposed outside the forming hole 410, leaving only the part inside the forming hole 410.

[0053] Please continue reading. Figure 8 The unloading structure 800 includes a fourth support platform 810, a push rod 8220, and an unloading block 830. The fourth support platform 810 is mounted on the third support platform 710, and the push rod 8220 is mounted on the fourth support platform 810, located above the forming disc 400. The unloading block 830 is mounted at the output end of the push rod 8220, and its position corresponds to the position of the notch 310. The shape of the unloading block 830 corresponds to the shape of the forming hole 410. When the push rod 8220 pushes the unloading block 830 to move, the unloading block 830 can push the glass product out of the forming hole 410.

[0054] Since the control panel 300 is fixed, while the forming plate 400 rotates relative to the control panel 300 (meaning the bottom of the forming hole 410 rotates relative to the control panel 300), if molten glass is directly dripped into the forming hole 410, the bottom of the molten glass will rub against the control panel 300 as the forming plate 400 rotates, causing wear and even causing the molten glass to adhere to the upper surface of the control panel 300. (See reference...) Figure 4 , Figure 5 as well as Figure 9 and Figure 10 To address the above issues, the molding disc 400 disclosed in this embodiment is provided with a baffle 910 at each molding hole 410, which can rotate with the molding disc 400. The baffle 910 is slidably connected to the molding disc 400 and can move along the axial direction of the molding hole 410. In this way, the baffle 910 can isolate the molten glass from the control disc 300, thereby preventing the molten glass from adhering to the control disc 300.

[0055] The baffle 910 is larger than the forming hole 410 to ensure complete isolation between the forming hole 410 and the control panel 300. The baffle 910 is smaller than or equal to the size of the notch 310 to ensure that the baffle 910 can move downward smoothly, and the size of the baffle 910 is adapted to the size of the slide groove 320, and the bottom of the baffle 910 can slide along the slide groove 320.

[0056] See Figure 9 and Figure 10 This embodiment also includes a first pusher 920, a slider 930, an elastic element, and a second pusher 940. The first pusher 920 is located at the notch 310. When the baffle 910 moves downward along the axis of the forming hole 410, the first pusher 920 can move radially outward along the control disk 300 to push the glass out of the baffle 910. The slider 930 is slidably connected to the control disk 300 and can move along the axis of the control disk 300. The first end of the slider 930 extends to the notch 310, and the first end of the slider 930 cooperates with the baffle 910 so that when the baffle 910 moves downward, the slider 930 can move radially outward along the control disk 300; the second end of the slider 930 is connected to the first pusher 920 so that when the slider 930 can move, it can drive the first pusher 920 to move synchronously. The two ends of the elastic element are connected to the control disk 300 and the slider 930 respectively. The elastic element causes the slider 930 to have a tendency to move inward along the radial direction of the control disk 300, that is, the elastic element causes the slider 930 and the first push block 920 to have a tendency to move away from the notch 310.

[0057] The second pusher 940 is slidably engaged with the baffle 910. The second pusher 940 can move relative to the baffle 910 along the radial direction of the forming disc 400, and the moving direction of the second pusher 940 is parallel to the moving direction of the first pusher 920. The second pusher 940 is disposed at the end of the baffle 910 facing the first pusher 920. A limiting groove and an inlet are provided on the side of the second pusher 940 facing the first pusher 920. The limiting groove extends along the height direction of the second pusher 940, and the inlet is located at the bottom end of the limiting groove. When the first push block 920 moves outward along the radial direction of the forming disc 400, the locking part on the first push block 920 will engage with the limiting groove from the entrance. When the first push block 920 continues to move outward, the second push block 940 will move downward, and the locking part will move relative to the second push block 940 within the limiting groove until the glass product is removed from the baffle 910. Since the locking part is engaged within the limiting groove, when the first push block 920 retracts, it will also drive the second push block 940 to move inward along the radial direction of the forming disc 400.

[0058] The height of the second pusher 940 is greater than the height of the forming hole 410. This way, when unloading, the unloading block 830 will abut against the second pusher 940 instead of pressing directly on the glass product. On the one hand, this can prevent the glass product from being deformed by pressure. On the other hand, it can also reduce the friction between the glass product and the baffle 910 when the glass product leaves the baffle 910, thereby avoiding wear on the glass product.

[0059] In this embodiment, the limiting groove can be set as a T-groove or a dovetail groove, and the shape of the snap-fit ​​part corresponds to the shape of the limiting groove. This ensures that the first push block 920 can drive the second push block 940 to retract when it retracts, thereby ensuring that the second push block 940 will not affect the next time the molten glass enters the forming hole 410, thus ensuring the accuracy of the shape of the glass product.

[0060] In this embodiment, to ensure the flatness of the bottom of the glass product, a groove 320 for guiding and restricting the second pusher 940 is not provided on the baffle 910. Since the unloading block 830 does not directly contact the glass product, a guide groove can be provided at the bottom of the unloading block 830. The guide groove is arranged radially along the forming disc 400. When the unloading block 830 moves up and down, the top of the second pusher 940 can exit or enter the guide groove.

[0061] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
