Description

Technical Field

[0002] Glass corner beads are a common decorative accessory, and their market demand is steadily increasing. Traditional multi-faceted polishing processes are time-consuming and labor-intensive, but are now becoming increasingly unsuitable for current production needs. Consequently, automated glass corner bead processing machines, such as the one disclosed in ZL201010537088.2, have emerged on the market.

The rotation driving gear 54 and the rotation driven gear 55 are provided with a transmission chain 56 for driving the glass rod clamping tube to rotate. A plurality of gears are provided in the transmission chain 56 at a position corresponding to the position between the rotation driving gear 54 and the rotation driven gear 55 for ejecting the transmission chain 56 from the rotation transmission gear.

The stopper rod 59 is fixed to the frame 1, and the distance between the top of the stopper rod 59 and the bottom of the glass rod clamping tube is 0 to 10 mm.

[0036] Working principle: The driving motor 2 on the frame 1 rotates and drives the No. 1 driving shaft 3 to rotate continuously. The continuously rotating No. 1 driving shaft 3 drives the two mutually meshing revolution driving gears 6 to rotate intermittently after passing through the intermittent divider 4, and makes the two revolution driving shafts 5 on the two revolution driving gears 6 rotate intermittently synchronously; the revolution driving shaft 5 can drive the multiple driving gears 9 connected thereto to drive the corresponding chains 8, driven gears 10 and revolution driven shafts 7 to rotate intermittently; because each glass rod clamping tube on each chain 8 is connected to a connecting plate 11, and the connecting plate 11 is rotatably sleeved on the glass rod through a sleeve hole. Outside the glass rod clamping tube, this enables the multiple vertically distributed chains 8 to drive the glass rod clamping tube to maintain a vertical shape and perform intermittent orbital conversion during intermittent revolution; a missing positioning plate 14 is connected between two adjacent connecting plates 11 on each chain 8, which can prevent the chain 8 from being loose, thereby reducing the swing of the glass rod clamping tube and improving the operation stability; the connecting plate 11 connected to the uppermost chain 8 can be slidably mounted on the top of the frame 1, and the top of the glass rod clamping tube is connected to a clamping ring 13 clamped above the uppermost connecting plate 11, so that the connecting plate 11 can stably hold up and drive the glass rod clamping tube, and the operation stability is high.

[0037] During the synchronized intermittent revolution of the two groups of glass rod holding tubes spaced apart in a racetrack-like annular pattern, the bottom ends of the glass rods held in the multiple glass rod holding tubes on one side of the shared side are heated to a molten state by the heating device. Specifically, the bottom ends of the glass rods move from one end of the heat collecting tank 53 in the heat collecting furnace 51 toward the other end, gradually approaching the flame spray gun 52, causing the temperature of the glass rods to gradually increase until they are heated to a molten state. When the glass rods approach the end where the flame spray gun 52 is located, the rotation mechanism drives the glass rod holding tubes to rotate. Specifically, the rotation motor 62 on the frame 1 drives the rotation driving gear 54 to rotate, and drives the transmission chain 56 and the rotation driven gear 55 to rotate. When the rotation transmission gear 50 at the top end of the glass rod holding tube passes the adjustment bearing 57, it engages with the transmission chain 56. The transmission chain 56 drives the glass rod holding tubes and the glass rods held therein to rotate via the rotation transmission gear 50, so that the bottom ends of the glass rods are uniformly heated by the flame spray gun 52.

[0038] As each set of glass rod clamping tubes continues to perform intermittent revolution, the bottom end of the glass rod is heated to melt, and the glass rod clamping tube moves to the corresponding die-casting device, and the two die-casting devices perform glass corner bead pressing operations synchronously; that is, the No. 1 drive shaft 3 drives the No. 4 drive shaft 32 to rotate synchronously through the No. 2 drive shaft 15, and when the raised portion of the retraction cam 33 on the No. 4 drive shaft 32 pushes the retraction power rod group 41, the retraction power rod group 41 stretches the positioning tension spring 40 to drive the No. 1 slide 35 to move relative to the frame 1, so that when the glass rod clamping tube revolves, the molten portion of the bottom end of the glass rod can move unhindered between the die-casting die 37 and the die-casting punch 38; subsequently, the raised portion of the retraction cam 33 is misaligned with the retraction power rod group 41, and the positioning tension spring 40 can pull a The No. 1 slide 35 and the retracting power rod group 41 are reset. At this time, the die-casting die 37 on the No. 1 slide 35 is tightly attached to the molten part of the bottom end of the glass rod, and the positioning groove 61 on the positioning piece 39 on the die-casting die 37 is engaged with the glass rod clamping tube to prevent the glass rod clamping tube from shaking during the die-casting process; then, the reciprocating drive structure 60 on the No. 1 slide 35 drives the No. 2 slide 36 to perform a reciprocating motion relative to the No. 1 slide 35 (the motor vertically connected to the No. 1 slide 35 drives the turntable to rotate, and the swing rod eccentrically connected on the turntable drives the No. 2 slide 36 to slide along the slide rail relative to the No. 1 slide 35). The die-casting punch 38 on the No. 2 slide 36 can press the molten part of the bottom end of the glass rod into the die-casting die 37 and then withdraw to its original position to realize the die-casting operation.

[0039] After the die-casting operation is completed, the raised portion of the retracting cam 33 pushes the No. 1 slide 35 to move again. At this time, the raised portion of the demoulding cam 34 on the No. 4 driving shaft 32 pushes the demoulding power rod group 43 to drive the demoulding head 42 to move toward the die-casting die 37, and the glass corner bead blank remaining in the die-casting die 37 is ejected for unloading.

[0040] Subsequently, each group of annularly distributed glass rod clamping tubes continues to perform intermittent revolution. After the current glass rod clamping tube can drive the horizontal knocking rod 58 to swing to the maximum angle and separate, the reset spring 63 can drive the knocking rod 58 to swing back and reset and knock on the bottom of the subsequent glass rod clamping tube, so that the bottom of the glass rod clamping tube produces a certain vibration, which helps to separate and discharge the glass corner beads adhered to the bottom of the glass rod; after the glass rod clamping tube is separated from the knocking rod 58, it can also pass through the horizontal blocking rod 59, which can block and separate the glass corner beads adhered to the bottom of the glass rod, thereby completing the glass corner bead separation and discharge action (a collecting hopper can be connected under the knocking rod 58, the blocking rod 59 and the die-casting die 37 to collect the glass corner beads).

[0041] When the glass rod clamping tube is located at the zipper material mechanism, the bottom of the glass rod has been fully cooled after a period of time. At this time, the zipper material mechanism pulls the glass rod clamped in the glass rod clamping tube downward a certain distance, making it convenient for the bottom end of the glass rod to continue heating and die-casting operations. That is, the No. 1 driving shaft 3 drives the No. 3 driving shaft 16 to rotate synchronously through the No. 2 driving shaft 15, and the convex parts of the opposite sides of the two opposite clamping side cams 19 on the No. 3 driving shaft 16 are misaligned with the two driving rods 25. At this time, the springs 24 at the bottom of the two pulling material connecting rods 22 can push the bottoms of the two pulling material connecting rods 22 outward; because the middle parts of the two pulling material connecting rods 22 are rotatably connected to the pulling material connecting block 21, when the bottoms of the two pulling material connecting rods 22 are pushed outward, the clamps 23 at the tops of the two pulling material connecting rods 22 can move inward to clamp the glass rod protruding from the bottom of the hoop tube 46; as the No. 3 driving shaft 16 rotates, the convex part of the clamping cam 17 on the No. 3 driving shaft 16 moves downward The unclamping power rod 31 is pushed and the unclamping tension spring 64 is stretched downward. The unclamping link 28 connected to the unclamping power rod 31 can drive the other unclamping link 28 to move downward synchronously through the unclamping connecting block 30. At this time, the unclamping blocks 29 at the top of the two unclamping links 28 move downward synchronously, and the two unclamping blocks 29 pull the hoop tube 46 downward through the raised outer edge 47 at the bottom end of the hoop tube 46, so that the elastic collet 45 releases the glass rod and stretches the compression spring 49 downward; then, the convex part of the pulling cam 18 on the third drive 16 pushes the pulling power rod 26 downward and stretches the pulling tension spring 27 downward, and the pulling link 22 connected to the pulling power rod 26 can drive the pulling connecting block 21 to move vertically. The straight guide block 20 moves downward and drives the other drawing connecting rod 22 on the drawing connecting block 21 to move downward synchronously (rollers can be set at the bottom of the two drawing connecting rods 22 and the corresponding parts of the driving rod 25, and clamps can be connected to the ends of the two driving rods, so that when the two drawing connecting rods 22 move downward, the rollers can slide relative to the clamps, thereby reducing the wear between the drawing connecting rods 22 and the driving rods 25 and improving durability); at this time, the two drawing connecting rods 22 that clamp the bottom of the glass rod through the top clamp 23 pull the glass rod downward relative to the hollow tube 44 for a certain distance during the downward movement; then, the raised part of the loosening cam 17 is misaligned with the loosening power rod 31, and the loosening tension spring 64 The loosening power rod 31, the two loosening connecting rods 28 and the loosening connecting block 30 are pulled upward and reset; the compression tension spring 49 pulls the sleeve tube 46 upward and resets it, and the elastic collet 45 re-clamps the glass rod through the annular constriction opening 48 on the inner side of its bottom end; then, the raised parts of the two clamping side cams 19 face and push the two driving rods 25 inward, so that the compression spring 24 pushes the bottom of the two pulling connecting rods 22 inward, so that the two clamps 23 at the top of the two pulling connecting rods 22 release the glass rod; then, the raised part of the pulling cam 18 is misaligned with the pulling power rod 26, and the pulling tension spring 27 pulls the pulling power rod 26, the two pulling connecting rods 22 and the pulling connecting block 21 upward and resets them.

[0042] The two sets of glass rod clamping tubes perform intermittent revolution synchronously, passing through the heating device, die-casting device, unloading mechanism and zipper mechanism in sequence, thereby realizing automatic heating, die-casting, unloading and loading operations of the glass rod.
