Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to equipment for producing glass products, and specifically relates to a flame heating device for producing glassware. Background Art

[0002] When producing glassware, it is usually necessary to heat the glass with a flame. For example, when producing glassware, the handle welding process is to weld the handle and the cup body together by melting the glass at the connection part. This requires using different lamp holders (flame heaters) to burn the welding parts of the cup body and the handle at the same time, so that their welding points reach a softened molten state, and then make the melting points of the cup body and the handle contact to connect them as a whole. And when heating parts of glassware of different sizes, it is also necessary to adjust the size, intensity and temperature of the flame sprayed by the flame heater to achieve the melting requirement as soon as possible without wasting energy.

[0003] When welding the cup body and the cup handle, the existing technology is to use different nozzles (also called lamp holders, nozzles, etc.) to spray flames to heat the welding parts of the cup body and the cup handle respectively. In the patent document with the publication number CN215327717U, a new type of heating device for a horizontal ampoule machine is disclosed, including a mounting plate, sleeves are installed at both ends of the top of the mounting plate, a telescopic rod is movably connected inside the sleeve, and the tops of the two telescopic rods are commonly connected to a slide rail, and a plurality of moving blocks are slidably connected to the slide rail, a fixed rod is installed on the top of the moving block, a mounting sleeve is installed on the top of the fixed rod, a flame nozzle is installed inside the mounting sleeve, and a flame outlet sleeve is provided at the outlet of the flame nozzle, a lifting mechanism for adjusting the height of the slide rail is provided at the bottom of the slide rail, and a spacing adjustment component is provided between two adjacent mounting sleeves; each flame outlet sleeve in the patent is connected to an oxygen delivery pipeline and a fuel delivery pipeline.

[0004] Therefore, each nozzle of the existing flame heater for burning the handle and body of the glass cup is connected to a set of gas supply pipelines to provide oxygen and combustible gas for the nozzle. When the size, intensity and temperature of the flame are different, the supply amount and ratio of oxygen and combustible gas are different and need to be adjusted respectively. Therefore, each lamp holder needs to be equipped with an oxygen pipeline and a combustible gas pipeline, and each pipeline needs to be equipped with a valve for controlling the flow. During the production process, after replacing the new glassware, it is necessary to adjust the flow control valve of each nozzle one by one to adjust the ventilation volume and the ratio of oxygen and combustible gas of each nozzle, and control the size, temperature and intensity of the flame sprayed by the nozzle. With such a structure, it takes a lot of time to adjust the equipment before production, especially when multiple glassware are produced on the same equipment at the same time, multiple lamp holders are required at the same time. Adjusting the equipment not only takes a lot of time, but the flames between different lamp holders are often inconsistent, resulting in different quality products produced by different lamp holders. Utility Model Content

[0005] In order to solve the problem in the prior art that each lamp holder needs to be equipped with an oxygen pipeline and a combustible gas pipeline, which is troublesome to adjust, the utility model provides a flame heating device for producing glassware, which can conveniently adjust the flame sprayed from the lamp holder.

[0006] The technical solution adopted by the flame heating device for producing glassware in the utility model is:

[0007] A flame heating device for producing glassware comprises a plurality of flame spraying tubes with flame spraying nozzles, an oxygen tube and a fuel gas tube connected to the flame spraying tubes, the flame spraying tubes are installed on a gas supply main pipe, the gas supply main pipe is connected to an oxygen tube and a fuel gas tube with electromagnetic valves capable of regulating flow respectively, and a valve for adjusting the size of the flame is installed on the flame spraying tubes.

[0008] A further improvement of the technical solution of the utility model is that the main gas supply pipe is connected to a lifting seat that drives the main gas supply pipe to move up and down through a pipe body seat, and the pipe body seat is fixed to the through groove on the lifting seat through a positioning bolt at its bottom.

[0009] A further improvement of the technical solution of the utility model is that the lifting seat moves up and down along the vertical guide rail.

[0010] A further improvement of the technical solution of the utility model is that a vertically arranged cylinder whose telescopic end is connected to the lifting seat is provided on the top of the vertical guide rail.

[0011] A further improvement of the technical solution of the utility model is that the vertical guide rail is connected to the first sliding seat through a horizontal position adjustment mechanism.

[0012] A further improvement of the technical solution of the utility model is that the horizontal position adjustment mechanism includes two fixed plates fixed on the first sliding seat, a horizontal adjustment seat movable left and right is arranged between the two fixed plates through a threaded rod, and the bottom end of the vertical guide rail is fixed on the horizontal adjustment seat.

[0013] A further improvement of the technical solution of the utility model is that: the gas supply main pipe is also connected to a second gas pipe with a check valve for supplying low-pressure gas to the flame-spraying pipe.

[0014] A further improvement of the technical solution of the utility model is that the flame spraying direction of the flame spraying nozzles provided on each flame spraying tube is in the radial symmetric direction of the flame spraying tube; when multiple welding points are required, multiple flame spraying nozzles can be provided which are arranged up and down.

[0015] Due to the adoption of the above technical solution, the technical advances achieved by the utility model include:

[0016] The utility model installs one or more flamethrower tubes on a gas supply main pipe, and supplies oxygen and gas to the gas supply main pipe and all flamethrower tubes through an oxygen pipe and a gas pipe. Compared with the prior art in which each lamp holder is connected to an oxygen pipe and a gas pipe, the oxygen pipe and the gas pipe are saved, the gas supply structure is simplified, and the cost can be reduced. The on-off of the gas and oxygen is controlled by electromagnetic valves respectively installed on the oxygen pipe and the gas pipe, and the flow and proportion of the oxygen and gas entering the gas supply main pipe are adjusted and controlled by a flow regulating valve and the like (it should be noted that if the electromagnetic valve itself has a flow control function, it is not necessary to install a flow regulating valve separately), so that the on-off, size and combustion temperature of the fire can be controlled; a valve for adjusting the size of the flame is installed on the flamethrower tube, so as to achieve the purpose of adjusting the size of the flame sprayed by the flame nozzle. Compared with the prior art that requires the concentration of oxygen in the oxygen pipe connected to each lamp holder and the concentration of gas in the gas pipe separately adjusted, the adjustment method of the utility model is simpler and easier to use.

[0017] The gas supply main pipe of the utility model is connected to the lifting seat, so that all the flamethrower tubes on the gas supply main pipe can be moved up and down at the same time. When the flamethrower tube needs to be replaced, the gas supply main pipe can be replaced as a whole, which simplifies the time for adjusting the equipment. The gas supply main pipe is connected to the through groove on the lifting seat through the pipe body seat, positioning bolts, etc., and is connected through the horizontal position adjustment mechanism. The front, back, left, and right positions of the gas supply main pipe and the flamethrower tube relative to the glassware parts can be adjusted. In addition, the gas supply main pipe can move up and down with the lifting seat, so that the flamethrower tube can leave the heating position without affecting the docking or other operations of the heated parts. The lifting and lowering of the gas supply main pipe or leaving the heating position is faster and more efficient when driven by a cylinder.

[0018] The gas pipe for supplying low-pressure gas connected to the gas supply main of the utility model can keep the flame of the flamethrower of the flamethrower tube without extinguishing the flame when heating is not required, so as to facilitate rapid ignition during the next heating. The check valve on the pipeline for providing low-pressure gas to the gas supply main can prevent flashback into the low-pressure gas pipeline when high-pressure gas and oxygen are introduced into the gas supply main. Different flamethrowers can be provided on each flamethrower tube of the utility model according to the shape or structure of different glassware. When the flame spraying direction is toward both sides, parts in the radially symmetrical direction can be heated simultaneously. When multiple welding points are required, multiple flamethrowers arranged up and down can be provided on the flamethrower tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The flame heating device of the utility model can be referred to in the specific setting Figure 1 , Figure 2 and Figure 3 . refer to Figure 1 , Figure 2 and Figure 3 It can be seen that the utility model includes a flame-spraying tube 71 provided with a flame-spraying nozzle 711, and the flame-spraying direction of the flame-spraying nozzle 711 is toward the welding part of the glassware parts. When welding a glass cup with a C-shaped cup handle, the flame-spraying nozzle 711 should be provided with two pairs of corresponding left and right. The distance between the two pairs of flame-spraying nozzles 711 corresponds to the distance between the upper and lower welding points of the C-shaped cup handle. Figure 1 , Figure 2 and Figure 3 The flame-spraying pipe 71 is vertically arranged on a horizontally arranged gas supply main pipe 716, and the number of flame-spraying pipes 71 connected to the gas supply main pipe 716 can be one or more, and the number of flame-spraying nozzles connected to the flame-spraying pipe can also be several. A valve 715 for adjusting the flame size is provided between each flame-spraying pipe 71 and the gas supply main pipe 716. Figure 1 , Figure 2 and Figure 3 Two gas pipes 714 and one oxygen pipe 713 are arranged on the gas supply main pipe 716. The two gas pipes 714 supply high-pressure gas and low-pressure gas respectively. The gas pipe 714 and the oxygen pipe 713 supplying high-pressure gas are connected to an external gas source through a flow regulating valve and a solenoid valve 717 respectively, and the gas pipe 714 supplying low-pressure gas is connected to an external gas source through a check valve 718. The flow regulating valve on the oxygen pipeline and the high-pressure gas pipe of the utility model is used to adjust the flow and ratio of oxygen and gas entering the gas supply main pipe, and the solenoid valve is used to switch on and off high-pressure oxygen and gas. When the flame heating device of the utility model does not need to heat, the solenoid valve 717 is closed, and only low-pressure gas is supplied to the gas supply main pipe 716 and the flamethrower 71 through the low-pressure gas pipeline and the check valve 718. At this time, the flamethrower 711 sprays out a low-pressure constant-burning flame; when it is necessary to heat the glassware parts, the solenoid valve 717 is opened. At this time, high-pressure gas and high-pressure oxygen are supplied to the gas supply main pipe 716 and the flamethrower 71 through the gas pipe 714 and the oxygen pipe 713. The flamethrower 711 sprays out a high-pressure molten flame, thereby melting the positions of the welding points of the cup handle and the cup body.

[0024] In order to facilitate the adjustment of the position of the gas supply main pipe 716 and the flamethrower nozzle of the flamethrower pipe in the utility model, continue to refer to Figure 1 , Figure 2 and Figure 3 A lifting seat 73 that can move up and down is arranged above the first sliding seat 13, and a pipe body seat 712 for installing a gas supply main pipe 716 is slidably arranged on the lifting seat 73, and valves such as a solenoid valve 717 and a check valve 718 can be respectively installed on the lifting seat 73; continue to refer to Figure 2 and Figure 3 The lifting seat 73 is provided with a slide groove, and a strip hole connected to the slide groove is provided below the slide groove, the tube body seat 712 is slidably arranged in the slide groove, and the bottom of the tube body seat 712 is threadedly connected with a positioning bolt 79 that passes through the strip hole. In this way, the front and rear positions of the flame spray tube can be adjusted so that the flame spray nozzle is aligned with the welding part of the heated part.

[0025] In order to enable the gas supply main pipe to move up and down and leave the heating and docking position of the parts, continue to refer to Figure 1 The lifting seat 73 is slidably connected to the vertical guide rail 77, and the first tube body seat 712 moves up and down along the vertical guide rail 77 as a whole with the lifting seat 73. A cylinder 78 whose telescopic end is connected to the lifting seat 73 is vertically arranged on the top of the vertical guide rail 77; the vertical guide rail 77 can be installed on the first sliding seat 13 through a horizontal position adjustment mechanism, so as to facilitate the horizontal adjustment of the distance between the flamethrower 71 and the parts to be heated.

[0026] The above-mentioned horizontal position adjustment mechanism can continue to refer to the specific setting Figure 1 ,according to Figure 1 It can be seen that the horizontal position adjustment mechanism includes a horizontal adjustment seat 75 installed on the first sliding seat 13, and a fixing plate 74 and a threaded rod 76 can also be installed between the first sliding seat 13 and the horizontal adjustment seat 75, so as to adjust the left and right position relationship of the flamethrower 711 relative to the glassware parts by adjusting the left and right position of the vertical guide rail 77.

[0027] The working principle of the flame heating device for producing glassware of the utility model is as follows: after replacing a new type or model of glassware, before making production preparations, the glassware parts that need to be heated after being clamped are installed, and then the gas supply main pipe with the corresponding flame-spraying tube is installed on the tube body seat 712, and the position of the tube body seat 712 is adjusted so that the flame-spraying nozzle of the flame-spraying tube is aligned with the part that needs to be heated. Then, by rotating the threaded rod 76, the position of the horizontal adjustment seat 75 on the first sliding seat 13 is adjusted left and right, and finally the left and right position relationship of the flame-spraying nozzle of the flame-spraying tube 71 relative to the heated part is adjusted, so that the flame-spraying tube 71 is located between the two heated parts (glass cup body and cup handle). Then adjust the ratio of high-pressure fuel gas and oxygen, and adjust the distance and size of the flame sprayed on each flame-spraying tube.

[0028] Open the low-pressure gas valve, introduce low-pressure gas into the gas supply main and ignite it at the flame nozzle.

[0029] When the utility model is used, the cylinder 78 drives the lifting seat 73, the gas supply main pipe 716, the flame-spraying pipe 71 and the flame-spraying nozzle 711 to move downward along the vertical guide rail 77, and then the solenoid valve 717 is opened, and high-pressure oxygen is supplied to the gas supply main pipe 716 through the oxygen pipe 713, and high-pressure gas is supplied to the gas supply main pipe 716 through the gas pipe 714. Under the action of high-pressure oxygen and high-pressure gas, the flame sprayed by the flame-spraying nozzle 711 becomes larger and the temperature increases, thereby melting the position of the part welding point. When the solenoid valve 717 is opened, the check valve 718 set on the low-pressure gas pipeline can prevent the utility model from backfire, thereby ensuring the safety of the utility model when in use.

[0030] When the welding points of the cup handle and the cup body are completely melted, the electromagnetic valve 718 is closed, and the cylinder 78 drives the lifting seat 73, the gas supply main pipe 716, the flame-spraying tube 71 and the flame-spraying nozzle 711 to move upward along the vertical guide rail 77 to the original position.

[0031] In the above embodiment, the utility model provides a flame heating device for producing glassware. The utility model supplies oxygen and fuel gas to the gas supply main and all flamethrower tubes through an oxygen tube and a fuel gas tube. Compared with the prior art in which each lamp holder is connected to an oxygen tube and a fuel gas tube, the oxygen tube and the fuel gas tube are saved, the gas supply structure is simplified, and the cost can be reduced. At the same time, the utility model can adjust the fuel gas concentration and pressure in the flamethrower tube through the valve provided, so as to achieve the purpose of adjusting the size of the flame sprayed from the flamethrower. Compared with the prior art that needs to separately adjust the concentration of oxygen in the oxygen tube and the fuel gas in the fuel gas tube connected to each lamp holder, the adjustment method of the utility model is simpler and easier to use.
