Description

Technical Field

[0001] This utility model relates to a forming furnace, and more particularly to a glass forming furnace. Background Technology

[0002] The shaping of glass involves placing a flat glass blank onto a mold and heating the mold to soften the glass. Then, through negative pressure or molding, the glass blank is pressed into the mold to form the shape corresponding to the mold. After cooling, a glass component with a specific shape is completed.

[0003] When using a glass forming furnace, different substances need to be added to mix with the glass raw material during the heating and softening process. In existing glass forming furnaces, the glass raw material tends to accumulate during heating, leading to uneven heating, increased heating time, and resource waste, resulting in poor practicality.

[0004] Therefore, a new type of glass forming furnace needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a glass forming furnace.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a glass forming furnace, including a furnace body, a stirring chamber formed in the furnace body, a forming box connected below the stirring chamber, and the forming box moving up and down along the furnace body through a lifting mechanism;

[0007] The lifting mechanism includes a driving shaft and a driven shaft arranged in parallel. A set of driving wheels is sleeved on the driving shaft at intervals, and a set of driven wheels is correspondingly sleeved on the driven shaft. The driving wheels drive the driven wheels to rotate.

[0008] A cavity is formed at the bottom of the molding box, and U-shaped slides are symmetrically formed on the two side walls of the cavity. A connecting plate is inserted into the U-shaped slide. One end of the connecting plate is fixed to the driven shaft and the other end is connected to the molding box. The connecting plate can move up and down along the U-shaped slide.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1The glass forming furnace shown includes a furnace body 10, a stirring chamber 1 formed inside the furnace body 10, a forming box 2 connected below the stirring chamber 1, and the forming box 2 moving up and down along the furnace body via a lifting mechanism 3; a heating tube is provided at the bottom of the forming box 2.

[0026] By setting up a stirring chamber with a stirring shaft and stirring blades, the glass raw materials entering the furnace are first stirred. The mixed raw materials then enter the forming box, where heating tubes heat the glass raw materials until glass is formed. During this process, a lifting mechanism is set up to ensure that the glass raw materials entering the forming box do not pile up. After moving up and down by the lifting mechanism, they are spread flat in the forming box, thereby reducing the heating time.

[0027] like Figure 3 As shown, the lifting mechanism 3 includes a driving shaft 31 and a driven shaft 32 arranged in parallel. A set of driving wheels is spaced on the driving shaft 31, and a set of driven wheels is correspondingly spaced on the driven shaft 32. The driving wheels drive the driven wheels to rotate.

[0028] By setting a drive shaft to drive the drive wheel set on it to rotate, and the drive wheel set to drive the driven wheel set on the driven shaft to rotate, the molding box can be moved up and down during the transmission process.

[0029] like Figure 2 As shown, a cavity 4 is formed at the bottom of the molding box 2. U-shaped slides 5 are symmetrically formed on both sides of the cavity 4. A connecting plate 6 is inserted into the U-shaped slide 5. One end of the connecting plate 6 is fixedly connected to the driven shaft 32, and the other end is connected to the molding box 2. The connecting plate 6 can move up and down along the U-shaped slide 5.

[0030] To ensure that the forming box can move up and down, causing the glass raw material inside to vibrate, the lower part of the furnace body is set as a cavity, so that the lifting mechanism can drive the forming box up and down, thereby vibrating the glass raw material and preventing it from accumulating inside the forming box.

[0031] By creating a U-shaped slide, the connecting plate can move up and down within the U-shaped slide. The connecting plate is connected to the forming box, which in turn drives the forming box to move up and down, allowing the glass raw material inside the forming box to flow and preventing accumulation inside the forming box.

[0032] Furthermore, the driving gear assembly includes a driving gear 33 located at the center of the driving shaft and a driving wheel 34, with driving wheels 34 symmetrically arranged on both sides of the driving gear 33. The driven gear assembly includes a driven gear 35 located at the center of the driven shaft and a driven wheel 36, with driven wheels 36 symmetrically arranged on both sides of the driven gear 35.

[0033] The drive shaft is sequentially equipped with a drive wheel, a drive gear 33, and a drive wheel 34, while the driven shaft is correspondingly equipped with a driven wheel, a driven gear 35, and a driven wheel 36. The drive wheel, drive gear 33, and drive wheel 34 correspond one-to-one with the driven wheel, driven gear 35, and driven wheel 36. The rotation of the drive wheel and drive gear drives the rotation of the driven wheel and driven gear.

[0034] Preferably, the driving gear 33 meshes with the driven gear 35, and the driving wheel 34 contacts the driven wheel 36. The driving gear 33, driving wheel 34, driven gear 35, and driven wheel 36 are all eccentric wheels.

[0035] The motor drives the drive shaft to rotate, which in turn drives the drive wheel, drive gear 33, and drive wheel 34 to rotate. Since the drive wheel, drive gear 33, and drive wheel 34 are connected to the driven wheel, driven gear 35, and driven wheel 36 respectively, the rotation of the drive wheel and drive gear drives the rotation of the driven wheel and driven gear. Because the driven wheel and driven gear are eccentric wheels, their rotation drives the driven shaft to move up and down, thereby driving the connecting plate to move up and down along the U-shaped slide, causing the molding box to move, thus preventing the raw materials from accumulating and reducing the heating time.

[0036] Furthermore, one end of the drive shaft 31 is connected to the output end of the motor 7, which is mounted on the side wall of the furnace body. By setting up the motor, the motor drives the drive shaft to rotate, thereby realizing the lifting operation.

[0037] Furthermore, the drive shaft 31 is located below the U-shaped slide 5, and the two ends of the driven shaft 32 are fitted into the bottom of the connecting plate 6. The motor drives the drive shaft to rotate, generating transmission power, which causes the drive wheel set to drive the driven wheel set to rotate. During the rotation of the driven wheel set, the driven shaft moves up and down, thereby realizing the movement of the molding box.

[0038] Preferably, sliders 61 are symmetrically arranged on both sides of the connecting plate 6, and slide rails 51 are correspondingly provided on the U-shaped slide rail 5. The connecting plate 6 moves up and down along the slide rails 51 via the sliders 61.

[0039] To improve the smoothness of the lifting mechanism's movement, sliders are installed on both sides of the connecting plate, and slide rails are opened on the U-shaped slide. By moving the sliders along the slide rails, the connecting plate can move along a predetermined track within the U-shaped slide, thus increasing the smoothness of the molding box's movement.

[0040] Preferably, the top of the furnace body 10 has a feed inlet 8, which is connected to the stirring chamber 1. A door is hinged to the surface of the furnace body 10, and an observation window 9 is provided on the door. A solenoid valve is provided between the stirring chamber 1 and the molding box 2.

[0041] In use, glass raw materials are poured into the mixing chamber through the feed inlet. The raw materials are stirred by the stirring blades and further conveyed by the stirring blades, so that the raw materials are transported from one side to the other. After the stirring is completed, the solenoid valve is opened, and the various raw materials in the mixing chamber fall into the molding box.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that:

[0044] The drive wheel has a protrusion, and the driven wheel has a recess that matches the protrusion. Therefore, during rotation, when the protrusion and the recess come into contact, the vibration generated on the forming box is enhanced, thereby preventing the glass raw material from accumulating in the forming box.

[0045] The purpose of this utility model is to provide a glass forming furnace. By setting a lifting mechanism at the bottom of the furnace body, the forming box is moved up and down by the lifting mechanism. During the movement of the forming box, the glass raw material entering it will not accumulate and will be spread flat in the forming box. At the same time, it will be heated by heating tubes until it is heated to form glass. This prevents the glass raw material from accumulating, thereby reducing the heating time and avoiding resource waste.

[0046] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
