Technical Field
[0001] The utility model relates to the field of glass cup processing equipment, in particular to a lifting type heating furnace. Background Art
[0002] Before the double-layer glass cup is sealed, the inner and outer shells need to be placed in an ordinary round furnace for heating. The air in the inner and outer shells of the heated inner and outer shells will expand due to heat. After the glass cup is sealed and cooled, a certain negative pressure will be formed in the inner and outer shells, which plays a role in heat insulation and anti-scalding when pouring boiling water.
[0003] For the double-layer glass cup sealing process, each group of machines requires 2 ordinary round furnaces. One round furnace contains the inner liner, and the other round furnace contains the outer shell. Due to the unreasonable structure of the round furnace, on the one hand, it is inconvenient for the operator to clamp the inner and outer shells, and scratches will be generated on the inner and outer shells; on the other hand, the heating time of the inner liner and the outer shell is different, which easily causes an increase in the defective rate, and the floor area of the 2 round furnaces is relatively large, affecting the reasonable layout of the workshop; in addition, when the ordinary round furnace opens to take out the inner liner and the outer shell, heat is released, and the heat directly hits the operator, and the temperature in the worker's working area rises rapidly, which is relatively dangerous. Content of the Utility Model
[0004] In order to make up for the deficiencies of the existing technology problems, the purpose of the utility model is to provide a lifting type heating furnace, which is convenient for the operator to clamp the inner and outer shells, the inner and outer shells are not easy to generate scratches, the heating time of the inner and outer shells is the same, the defective rate is reduced, the floor area is saved, and it is convenient for the layout of the production workshop;
[0005] At the same time, it solves the problem that when the ordinary round furnace opens to take out the inner liner and the outer shell, heat is released, and the heat directly hits the operator, and the temperature in the worker's working area rises rapidly, which is relatively dangerous.

[0034] A workbench 4 is provided inside the fuselage 2, and an operation area is formed between the workbench 4 and the heating furnace 3. The operation area is in a semi-surrounded state and faces the working direction of the operator. Inside the fuselage below the workbench 4, there are several groups of lifting components 5 distributed at annular intervals.

[0035] A heating port 8 corresponding to the cup fixing mold 7 is provided on the lower end surface of the heating furnace 3. All the heating ports 8 are distributed in an arc shape in two rows, and the two arcs are concentric;
[0036] An electric control box 9 is provided on the outer wall of the fuselage. The PLC controller of the electric control box 9 controlling the lifting component is electrically connected, and its on and off are controlled by an operation button. This kind of electric control connection belongs to a conventional connection method.
[0037] Furthermore, several support legs 10 are provided at the bottom of the frame 1, and an adjusting base foot 11 is installed at the bottom of each support leg, which can adjust the height of each support leg to ensure the level of the entire fuselage and the workbench.
[0038] Furthermore, the entire fuselage 2 is a hollow shell, and heat insulation cotton (not shown in the figure) is attached or filled inside the shell, which can ensure that the temperature of the outer periphery of the fuselage does not rise too high during operation and affect the working environment.
[0039] Furthermore, referring to the appendix Figure 5, the lifting assembly 5 includes a cylinder 5-1, the upper end of the cylinder 5-1 is fixed to the workbench 4, the upper end of the piston rod of the cylinder passes through the workbench and is provided with a heat insulation rod 5-2, and a support plate 6 is installed at the upper end of the heat insulation rod 5-2. The heat insulation rod 5-2 can ensure that heat is transferred to the fuselage through heat conduction, thereby increasing the ambient temperature around the fuselage.
[0040] Furthermore, guide rods 5-3 are respectively provided on both sides of the cylinder 5-1. The piston rod of the cylinder and the lower ends of the two guide rods are suspended, and the upper ends of the two guide rods are fixed to the lower end surface of the support plate 6.
[0041] Furthermore, heat insulation sleeves 5-4 are installed on the workbench at the corresponding positions of the guide rods 5-3. The guide rods 5-3 pass through the heat insulation sleeves 5-4 up and down. The heat insulation sleeves 5-4 can ensure that heat is transferred to the workbench and then to the entire fuselage through heat conduction, thereby increasing the ambient temperature around the fuselage.
[0042] Furthermore, the cup fixing mold 7 includes an inner cup mold 7-1 and an outer cup mold 7-2. Figure 5 Among them, the inner liner (inner cup) and the outer shell (outer cup) are sleeved on the inner cup mold 7-1 and the outer cup mold 7-2. The inner cup mold and the outer cup mold have the same shape. Both of them include a barrel body, and a column body is provided at the bottom of the barrel body. The gap between the column body and the barrel body matches the mouth of the inner cup or the outer cup; the bottom of the barrel body uses a graphite material base, and the column body can also use graphite material. This structure will not have too high a temperature during the heating process, and thick-bottom products can be directly placed on the base and sent to the furnace for heating without preheating.
[0043] Furthermore, the inner cup mold 7-1 and the outer cup mold 7-2 are arranged along the front-rear direction, and the inner cup molds 7-1 and the outer cup molds 7-2 at the upper ends of several cup fixing molds are distributed on two concentric circles.

After being taken out, they are placed on the sealing machine of the next process for sealing, and the defective rate of the produced products is relatively low; compared with the initial single circular furnace for mixed heating of the inner cup and the outer cup, during the picking process, it is easy to scratch other cups (which may be the inner cup or the outer cup) during the clamping process; compared with two circular furnaces for separately firing the inner cup and the outer cup, there is also a situation where other cups (either the inner cup or the outer cup) are scratched during the clamping process. In both of the above two methods, the heating time cannot be controlled to be the same, which will also increase the defective rate for subsequent sealing.
[0045] In summary, compared with the traditional prior art, the present invention has many advantages in the actual use process as follows:
[0046] 1. Energy saving and cost reduction:
[0047] Replacing the ordinary round furnace with a lifting furnace can reduce the number of round furnaces for each group of machines by one. The total heating power of the original two ordinary round furnaces is 30KW, while the heating power of the lifting furnace is only 12KW, which can significantly reduce energy consumption. This process can reduce the production cost of each product by about 0.04 yuan.
[0048] 2. Reduce the heating-up time:
[0049] Compared with the ordinary round furnace, the furnace chamber space is much smaller. When the set temperature of the heating furnace is the same (510°C), the heating-up time is reduced from the original 40 minutes to 5 minutes.
[0050] 3. Reduce the scratches on the bladder shell:
[0051] Adopting a semi-circular design and moving the furnace chamber upward, and using a lifting method in the structure, which facilitates the operator to horizontally pick up the bladder shell and reduces the scratch problem generated during the picking process.
[0052] 4. Sufficient and uniform heating time:
[0053] The lifting furnace has 10 working stations (which can be set to multiple according to the actual situation, depending on the proficiency of the operator and the factory space layout). Each working station can place 2 sets of bladder shells. Press the operation button, and the first working station will automatically rise to send the bladder shell into the furnace chamber for heating; press the operation button again, and the heated bladder shell on the first working station will automatically descend, be taken out and placed on the sealing machine for firing, then 2 sets of bladder shells are placed on the first working station again, and then circulated in turn. The operation is simple, the picking order will not be chaotic, and the heating time of the bladder shells is synchronous, sufficient and uniform.
[0054] 5. No preheating for thick-bottom products:
[0055] When using an ordinary round furnace, all thick-bottom products need to be preheated and then placed in the round furnace for heating to prevent the phenomena of bottom breakage and bottom dropping due to excessive temperature difference. The working station of the lifting furnace is specially designed and uses a graphite bottom tray. This structure will not have too high a temperature during the heating process, and thick-bottom products can be directly placed on the bottom tray and sent into the furnace chamber for heating without preheating.
[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
