Description

Technical Field

[0001] This utility model relates to the field of electric melting furnace technology, specifically a large-diameter glass rod electric melting furnace. Background Technology

[0002] An electric melting furnace for glass rods is a device used to heat and melt glass rods, commonly used in glass manufacturing, glass processing, and scientific research. The furnace operates on the principle of electric heating, using resistance heating to heat the glass rod to its melting point, thus melting the glass. Compared to traditional fuel-heated furnaces, electric melting furnaces offer advantages such as high heating precision, accurate temperature control, and uniform heating.

[0003] When melting glass rods in an electric melting furnace, the rods cannot be directly and completely placed into the furnace to prevent thermal stress breakage. Therefore, operators must hold the rods and slowly lower them into the furnace. However, holding the rods for extended periods causes muscle soreness in the operator's arms, making it difficult to push the rods slowly and evenly. Furthermore, the high temperature at the furnace's inlet also affects the operator's work. Therefore, to address these issues, a large-diameter glass rod electric melting furnace is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a large-diameter glass rod electric melting furnace.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The large-diameter glass rod electric melting furnace of this utility model includes an electric melting furnace body, a feed port is provided at the top of the electric melting furnace body, and a discharge port is provided at the bottom of the electric melting furnace body; a hollow fixed frame is fixedly installed at the top of the electric melting furnace body, electric push rods are fixedly installed on both sides of the fixed frame, and through slots are provided on both sides of the electric melting furnace body. A rectangular frame is slidably connected in the through slots, and the output end of the electric push rod is fixedly connected to the rectangular frame. A servo motor is fixedly installed in one end of the two rectangular frames that are close to each other, and a rotating column is fixedly installed at the output end of the servo motor.

[0006] Furthermore, several anti-slip convex balls are fixedly installed on the surface of the rotating column.

[0007] Furthermore, two symmetrically arranged sliding grooves are provided in the fixed frame, a sliding plate is slidably connected in the sliding groove, and an elastic element is fixedly installed in the sliding groove, with one end of the elastic element fixedly connected to the sliding plate.

[0008] Furthermore, an arc-shaped guide plate is fixedly installed on the top of the skateboard, and a guide post is rotatably connected to one side of the guide plate.

[0009] Furthermore, the slide plate and the slide groove are connected in a sealed sliding connection, the elastic element is a hollow elastic ball, the surface of the elastic element is provided with a shrinkage hole, a hollow rectangular block is fixedly installed on the top of the fixed frame, one side of the rectangular block is provided with an air outlet, and the rectangular block and the slide groove are connected by an air guide pipe.

[0010] Furthermore, a sealing gasket, made of flexible material, is fixedly installed at one end of the two slide plates that are close to each other.

[0011] The advantages of this utility model are:

[0012] 1. When a glass rod needs to be placed into the electric melting furnace for processing, this utility model activates two electric push rods, causing them to move two rectangular frames away from each other, thus facilitating the passage of one end of the glass rod through the frames. The downward movement of the glass rod is then temporarily halted, and the two electric push rods are activated again to move the two rectangular frames closer together. Two rotating columns and several protruding balls on the surface clamp the glass rod, allowing the operator to release it. A servo motor within the rectangular frames drives the rotating columns and protruding balls, moving the glass rod towards the furnace's feed inlet. This eliminates the need for the operator to hold the glass rod for extended periods, allowing it to move slowly and steadily into the furnace, preventing thermal stress breakage and reducing the time the operator spends at the high-temperature feed inlet. Furthermore, to maximize the processing of glass rods, this product features a large-diameter feed inlet, accommodating a wider range of glass rods.

[0013] 2. This utility model closes the feed inlet of the electric melting furnace body by installing two sliding plates, reducing the entry of impurities. When processing with a glass rod, the glass rod first contacts the arc-shaped guide plate and several guide posts, squeezing and pushing open the two guide plates and two sliding plates, thereby increasing the gap between the two sliding plates and facilitating the glass rod to enter the fixed frame. The flexible sealing gasket at one end of the sliding plate is always in contact with the glass rod, preventing the hard material of the sliding plate from damaging it. The sliding plates block a large amount of dust and impurities, preventing them from affecting the quality of the glass rod after melting and forming. They also allow the glass rod to enter the fixed frame and prevent heat dissipation from the feed inlet from affecting the workers. When there are many impurities on the fixed frame, sliding the sliding plates causes the gas in the elastic element to be squeezed through the constriction orifice and sprayed into the groove. Pushed by the sliding plates, the gas enters the rectangular block through the air guide pipe and is then blown towards the top of the fixed frame through the air outlet of the rectangular frame, thus blowing off the impurities at the top of the fixed frame and preventing them from falling into the electric melting furnace body through gaps.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a large-diameter glass rod electric melting furnace includes a furnace body 1. The furnace body 1 has a feed inlet 2 at its top and a discharge outlet 3 at its bottom. A hollow fixed frame 4 is fixedly installed on the top of the furnace body 1. Electric push rods 5 are fixedly installed on both sides of the fixed frame 4. Through slots 6 are opened on both sides of the furnace body 1, and rectangular frames 7 are slidably connected within the through slots 6. The output ends of the electric push rods 5 are fixedly connected to the rectangular frames 7. A servo motor 8 is fixedly installed in one end of the two rectangular frames 7 that is close to each other. A rotating column 9 is fixedly installed at the output end of the servo motor 8. Several anti-slip protruding balls 10 are fixedly installed on the surface of the rotating column 9.

[0023] During operation, when a glass rod needs to be placed into the electric melting furnace body 1 for processing, two electric push rods 5 are activated, causing them to move two rectangular frames 7 away from each other, thus facilitating the passage of one end of the glass rod through the two rectangular frames 7. The downward movement of the glass rod is then temporarily halted, and the two electric push rods 5 are activated again, moving the two rectangular frames 7 closer together. The glass rod is then clamped by two rotating columns 9 and several protruding balls 10 on the surface (which act as anti-slip devices). At this point, the operator can release the glass rod. A servo motor 8 inside the rectangular frame 7 drives the rotating columns 9 and the protruding balls 10, moving the glass rod towards the feed inlet 2 of the electric melting furnace body 1 (glass rods of the same diameter can continuously use the two rectangular frames 7 with pre-set gaps, eliminating the need for frequent adjustments). This frees the operator's hands from prolonged holding of the glass rod, allowing it to move slowly and evenly into the electric melting furnace body 1, preventing thermal stress breakage and reducing the time the operator spends at the high-temperature feed inlet 2. In order to process glass rods as much as possible, the feed inlet 2 of this product is designed to be a large diameter feed inlet 2, which can be adapted to a wider range of glass rods.

[0024] Two symmetrically arranged sliding grooves 11 are provided inside the fixed frame 4. A slide plate 12 is slidably connected in the sliding groove 11. An elastic element 13 is fixedly installed in the sliding groove 11, and one end of the elastic element 13 is fixedly connected to the slide plate 12. An arc-shaped guide plate 14 is fixedly installed on the top of the slide plate 12, and a guide post 15 is rotatably connected to one side of the guide plate 14.

[0025] Specifically, the slide plate 12 and the slide groove 11 are connected in a sealed sliding manner. The elastic element 13 is a hollow elastic ball with a shrinkage hole on its surface. A hollow rectangular block 17 is fixedly installed on the top of the fixed frame 4. One side of the rectangular block 17 has an air vent. The rectangular block 17 and the slide groove 11 are connected by an air guide pipe. A sealing gasket 16 is fixedly installed at one end of the two slide plates 12 that is close to each other. The sealing gasket 16 is made of flexible material.

[0026] During operation, due to the relatively large size of the feed inlet 2 of the electric melting furnace body 1, dust and other impurities easily enter through it, affecting the melting and processing of glass rods. By installing two sliding plates 12, the feed inlet 2 of the electric melting furnace body 1 is closed, reducing the entry of impurities. When processing the glass rod, it first contacts the curved guide plate 14 and several guide posts 15, squeezing and pushing the two guide plates 14 and the two sliding plates 12 apart, thereby increasing the gap between the two sliding plates 12 and facilitating the glass rod's entry into the fixed frame 4. Furthermore, the flexible sealing gasket 16 at one end of the sliding plate 12 remains in contact with the glass rod, preventing the rigid material of the sliding plate 12 from damaging it. The sliding plates 12 effectively block a large amount of dust and impurities, preventing them from affecting the quality of the melted and processed glass rod, while also allowing the glass rod to enter the fixed frame 4 and preventing heat dissipation from the feed inlet 2 from affecting the workers.

[0027] When there are many impurities on the fixed frame 4, the sliding plate 12 is used to squeeze the gas in the elastic member 13 through the shrinkage hole into the slide groove 11. Under the push of the sliding plate 12, the gas enters the rectangular block 17 through the air guide pipe and is blown to the top of the fixed frame 4 through the air outlet of the rectangular frame 7, thereby blowing off the impurities on the top of the fixed frame 4 and preventing the impurities from falling into the electric melting furnace body 1 through the gap.

[0028] Working principle: When a glass rod needs to be placed into the electric melting furnace body 1 for processing, two electric push rods 5 are activated, causing them to move two rectangular frames 7 away from each other, thus facilitating one end of the glass rod to pass through the two rectangular frames 7. At this point, the downward movement of the glass rod is temporarily halted, and the two electric push rods 5 are activated again to move the two rectangular frames 7 closer together. The glass rod is then clamped by two rotating columns 9 and several protruding balls 10 on the surface, at which point the operator can release the glass rod. The servo motor 8 inside the rectangular frame 7 drives the rotating columns 9 and the protruding balls 10, thus moving the glass rod towards the feed inlet 2 of the electric melting furnace body 1.

[0029] Because the feed inlet 2 of the electric melting furnace body 1 is relatively large, dust and other impurities can easily enter through it, affecting the melting and processing of glass rods. By installing two sliding plates 12, the feed inlet 2 of the electric melting furnace body 1 is closed, reducing the entry of impurities. When processing with glass rods, the glass rods first contact the curved guide plate 14 and several guide posts 15, squeezing and pushing the two guide plates 14 and the two sliding plates 12 apart, thereby increasing the gap between the two sliding plates 12 and facilitating the entry of the glass rod into the fixed frame 4. When there are many impurities on the fixed frame 4, sliding the sliding plate 12 causes the gas in the elastic element 13 to be squeezed through the constriction orifice and sprayed into the slide groove 11. Pushed by the sliding plate 12, the gas enters the rectangular block 17 through the air guide pipe and is then blown towards the top of the fixed frame 4 through the air outlet of the rectangular frame 7, thus blowing off the impurities at the top of the fixed frame 4 and preventing them from falling into the electric melting furnace body 1 through gaps.
