Description

Technical Field

[0001] The invention relates to the technical field of glass forming, in particular to a glass tube forming device with an angle self-adjusting function. Background Art

[0002] In our daily life, there are various kinds of lamps, especially glass lampshades are widely used in ceiling lamps. The main reasons are that glass lampshades have good light output, long life, easy cleaning and relatively high quality of life. Among them, more and more home decorations use ceiling lamps as indoor lighting fixtures. Unlike plastic, which will turn yellow after a long time of use, in order to solve the existing shape of glass lamps, glass forming technology is usually used. Glass forming is the process of transforming molten glass into products with geometric shapes. This process is called one-time forming of glass or hot end forming.

[0003] During this processing, the glass tube needs to be heated for a long time so that the operator can make various shapes. Although there are various casting methods now, the cast lampshades are usually rough and easily mixed with impurities, which has a significant impact on subsequent processing work. Therefore, the operation of hot-melt glass forming cannot be replaced. However, this operation is usually cumbersome and also puts a great test on the operator's level. Many defective products often appear, resulting in a large amount of material waste. The reason for these defective products is mostly due to uneven heating and large differences in thickness during molding. Summary of the Invention

[0004] The object of the present invention is to provide a glass tube forming device with an angle self-adjusting function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the forming device includes a forming chassis, a feed box is provided on the forming chassis, a feed motor is provided in the feed box, a transmission assembly is provided on the output end of the feed motor, a positioning plate is provided at the output end of the transmission assembly, a locking mold is provided on the positioning plate, a softening seat is also provided on the forming chassis, a softening spray gun and a pressurized spray gun are provided on the softening spray gun, an igniter is provided on the softening spray gun, a flame corrector is provided on the end of the softening seat away from the softening spray gun, a forming frame is provided on the side of the softening seat away from the positioning plate, the forming frame is slidably connected to the forming chassis, teeth are provided at the bottom end of the forming frame, a feed motor is provided in the forming chassis, the output end of the feed motor is meshed with the bottom end of the forming frame, a mounting seat is provided on the forming frame, and a forming Molding tool, a protective cover is provided on the molding chassis, and a control microcomputer is provided on the molding chassis. When the glass tube is formed, the glass primary tube is first fed into the feed box and passes through the positioning plate. The locking mold on the positioning plate will lock the glass primary tube, and then the feeding motor is started by the control microcomputer. The feeding motor will drive the transmission component to rotate, and the rotation of the transmission component drives the positioning plate to rotate. Then the feed motor will drive the molding frame to move toward the glass primary tube, and the molding tool is extended into the glass primary tube. Under the action of the molding seat, it is offset, and the igniter on the softening seat is started. The softening spray gun and the pressurized spray gun work to spray combustible gas, and then the processing area is heated. Wait until the molding tool is completely separated from the glass primary tube, and the glass primary tube will be processed.

[0006] The transmission assembly includes a transmission column, which is rotatably connected to the feed box. The transmission column is connected to the output end of the feed motor through a pulley. A transmission gear is provided on the transmission column, and a through-hole gear is provided on the feed box. The through-hole gear is engaged with the transmission gear, and the through-hole gear is rotatably connected to the feed box. When the feed motor is working, the feed motor will drive the transmission gear on the transmission column to rotate, and the transmission column will drive the transmission column to rotate, and the transmission column will also drive the through-hole gear to rotate, and the through-hole gear will drive the positioning disk to rotate, and the glass outlet tube will pass through the through-hole gear.

[0007] A feed port is provided on the positioning plate, and the axis of the feed port is the same as the rotation axis of the through-hole gear. The through-hole gear is connected to the positioning plate. A plurality of locking grooves are provided on the positioning plate. The locking molds are slidably connected with the corresponding locking grooves respectively. A locking column is provided on the positioning plate. The locking column is in sliding contact with the corresponding locking mold. After the glass outlet tube passes through the through-hole gear and the positioning plate, the locking mold will slide in the locking groove. After waiting for the locking mold to stick to the glass primary tube, the locking column is tightened. The end of the locking column away from the wrench will stick to the locking mold, and the locking mold will complete the positioning operation.

[0008] The locking mold includes a sliding frame, which is embedded in the locking groove and slidably connected to the locking groove. A side applicator is installed on the sliding frame, and a protective rubber sleeve is provided on the side applicator. A locking spring is provided in the sliding frame, and both ends of the locking spring are respectively against the sliding frame and the side applicator. A spring receiving nut is provided in the sliding frame, and the locking spring is embedded in the spring receiving nut and engaged with the thread of the spring receiving nut. Slide the sliding frame in the locking groove and wait for the protective rubber sleeve on the side applicator to stick to the glass primary tube. Then continue to move the sliding frame and the sliding frame will be locked by the locking column. Since the elastic force of glass primary tubes of different thicknesses is different, it is necessary to adjust the length of the locking spring according to different specifications of glass primary tubes. By adjusting the position of the spring receiving nut, the length of the locking spring will be limited, and the distance of its elastic deformation will also change, which can adapt to the qualitative operation of glass primary tubes of different thicknesses.

[0009] A softening frame is provided on the softening seat, and the softening frame is rotatably connected to the softening seat. A softening motor is provided on the forming chassis. A swing frame is provided on the output end of the softening motor, and the swing frame is slidably connected to the bottom end of the softening frame. The flame corrector is provided on the softening frame, and the softening motor is inductively connected to the feed motor. In the process of softening the glass primary tube, when the flame is sprayed, the direction of the flame needs to be adjusted. The softening motor will drive the swing frame to rotate, and the swing frame will adjust the position of the flame corrector. When the position of the flame corrector changes, the angle of the flame spray will be deflected. At the same time, the spray angle of the pressurized spray gun and the softening spray gun can also be rotated, and the angle deflection effect can also be achieved, thereby realizing the multi-angle heating effect of the glass primary tube, and its progress corresponds to the progress of the feed motor.

[0010] The flame corrector includes a first correction ring and a second correction ring, each of which is slidably connected to a softening frame. The softening frame is provided with an adjustment servo, and an adjustment gear is provided at the output end of the adjustment servo. The first correction ring and the second correction ring are respectively provided with teeth, and the teeth on the first correction ring and the second correction ring respectively mesh with the adjustment gear. The adjustment motor is inductively connected to the feed motor, and the adjustment motor and the feed motor are electrically connected to the control microcomputer. During the adjustment of the glass primary tube, the adjustment servo will drive the adjustment gear to rotate, and the adjustment gear drives the first correction ring and the second correction ring to adjust their positions on the softening frame, thereby changing the arc of the attracted flame, so that the flame can better cover the entire portion of the glass primary tube that needs to be softened, avoiding uneven deformation or cracking due to temperature differences. The position change corresponds to the progress of the feed motor. When the turning angle is large, the distance between the first correction ring and the second correction ring will be reduced. When the turning angle is small, the distance between the first correction ring and the second correction ring will be reduced.

[0011] A correction motor and a correction ring are respectively provided in the first correction ring and the second correction ring. Teeth are provided on the correction ring. The output end of the correction motor meshes with the teeth of the correction ring. Anti-damage rings and multiple adjustment blades are respectively provided on the inner circle of the correction ring. Each adjustment blade is connected to the anti-damage ring. The correction motor is electrically connected to the control microcomputer. During the flame correction process, the correction motor will drive the correction ring to rotate. The adjustment blades in the correction ring generate negative pressure, which will drive air flow, thereby extending the length of the flame, thereby changing the distance and curvature of the flame extension, and the anti-damage ring prevents long-term flame heating from damaging the adjustment blades, thereby extending the service life of the adjustment blades.

[0012] The forming frame includes a forming sub-frame and a support seat. The forming sub-frame is slidably connected to the support seat. The support seat is engaged with the output end of the feed motor. A forming cylinder is installed on the forming frame. The output end of the forming cylinder is connected to the forming sub-frame. The forming cylinder is electrically connected to the control microcomputer. The mounting seat is set on the forming sub-frame. During forming, the cooperation of the forming frame is required to form a specific angle. The forming cylinder will pull the forming sub-frame to move. The movement of the forming sub-frame can adapt to the bending angle of the glass tube, and is used in conjunction with the feed motor to determine the forming length and forming position of the glass tube.

[0013] A forming motor is provided on the forming sub-frame, and the output end of the forming motor is connected to the mounting base. A temperature scanner is provided on the mounting base. The temperature scanner is connected to the forming cylinder and the forming motor inductor through a wire. The temperature scanner is set between the softening frame and the mounting base. During the forming operation, the forming motor will drive the mounting base to swing, so as to adapt to the full angle of the glass primary tube forming, and the temperature scanner will scan the temperature of the glass primary tube, thereby detecting the temperature information at different positions and providing timely feedback to avoid the problem of burning leakage caused by the workpiece being too thin.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention adopts a buffer-type locking mold, which has a very good clamping effect on glass tubes of different models. It can not only reduce scratches on the glass, but also avoid the problem of glass tube breakage due to large shaping force, and can adapt to the performance of glass tubes of different specifications.

[0016] 2. The present invention adopts a structural component with automatic flame adjustment. By predicting the forming angle of the glass tube during the forming process, the flame clamping range of the glass tube is adjusted, so that the glass tube forming effect is better. At the same time, it can also avoid the problem of uneven thickness of the product due to uneven softening and can also significantly reduce the problem of breakage.

[0017] 3. The present invention adopts a structural component with automatic scanning of the forming speed. By scanning the temperature of the glass tube after scanning and forming, and then adjusting the speed of the feed motor, the problem of glass tube cracking due to excessive forming angle can be fully avoided.
