Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass product manufacturing, in particular to a fusion machine and process for hollow glass brick processing. BACKGROUND

[0002] In the current building material market, hollow glass bricks are widely used due to their aesthetic and energy-saving characteristics. Hollow glass bricks, also known as glass bricks or glass blocks, are a type of building material composed of an upper concave glass half and a lower concave glass half combined through fusion welding or other bonding methods. The interior is typically hollow. In the production process of hollow glass bricks, a fusion machine is a core and essential equipment. Its main function is to fuse two pre-pressed or blow-formed upper concave glass halves and lower concave glass halves together to form a sealed hollow cavity.

[0003] In order to improve the thermal and sound insulation performance of hollow glass bricks, it is sometimes necessary to fill them with inert gas or achieve a vacuum state. However, the current fusion process usually involves first fusing the two glass bricks under normal pressure, then drilling or leaving a hole for vacuum pumping and gas filling, which not only increases the process and prolongs the production cycle, but also may introduce secondary pollution or affect the sealing. If fusion and cavity environment control can be performed simultaneously, it will be a significant technical breakthrough. SUMMARY

[0014] Preferably, the heating assembly is arranged on the upper side of the fusion platform, the heating assembly is an annular induction heater which surrounds the joint area of the upper clamp and the lower clamp to achieve local preheating.

[0015] Preferably, based on the above-mentioned fusion machine for processing hollow glass bricks, the processing steps include:

[0016] S1: raw material preparation and mixing:

[0017] To ensure the uniformity of the glass composition, the carefully selected core raw materials such as quartz sand, soda ash, limestone, and feldspar, as well as a small amount of additives, must be precisely weighed and thoroughly mixed according to the precise formula.

[0018] S2: Melting

[0019] The mixed raw materials are fed into a high-temperature glass furnace and completely melted at a temperature of 1500-1600°C to obtain a clear and homogeneous glass melt.

[0020] S3: Compression molding:

[0021] After the molten glass is poured out of the furnace, it is cut into droplets of a specific weight, which are then pressed into molds and shaped by a press into upper and lower concave glass blanks of uniform size.

[0022] S4: Joint preheating treatment:

[0023] The newly formed upper concave glass half-bulb and lower concave glass half-bulb are stacked on the preheating input conveying device in an alternating pattern of one positive and one negative through the transfer equipment. During the process of conveying to the welding platform, the inner concave part is preheated by the heating device on the conveying device.

[0024] S5: Positioning and clamping:

[0025] T1: Positioning and clamping of the upper concave glass half-form;

[0026] The lower clamp is guided by rollers and limited by locking pins to achieve rapid and accurate positioning of the concave glass half blank; then, the upper clamp is driven by cylinders and electric push rods, and its slots precisely engage with the flared edge of the half blank to complete efficient clamping.

[0027] T2: Concave glass preform positioning and clamping;

[0028] Subsequently, the glass half-form with the flared edge facing down is quickly positioned by the rollers and clamping shafts of the lower clamp and the continuous transfer of the input conveyor. Then, the lower clamp's irregular plate is rotated by the electric push rod, and its slot precisely engages with the flared edge of the half-form, completing the rapid clamping.

[0029] S6: Welding pretreatment;

[0030] The second cylinder drives the lower clamp to move the lower concave glass half-blank upward. When the distance between it and the upper concave glass half-blank is 1cm, the heating component on the support frame locally heats the concave parts of both to a hot-melt state. The second cylinder continues to advance until the lower concave glass half-blank and the upper concave glass half-blank come into contact. At this time, the front and rear seams of the lower concave glass half-blank and the upper concave glass half-blank are first fused together, and then the left and right seams are fused together until a vacuum cavity is formed inside the lower concave glass half-blank and the upper concave glass half-blank.

[0031] S7: Vacuumizing and air-filling treatment:

[0032] The electric telescopic rod drives the metal plug-in plate to be inserted into the vacuum cavity between the glass half blanks, and the bent connecting pipe is pressed to make the sealing cavity expand, and the sealing plate is tightly attached to the inner recess of the glass by the folding frame, forming a local sealing micro-environment at the joint. Then, the air exhaust device evacuates the cavity, and the air supply device injects inert gas;

[0033] S8: Fusion treatment;

[0034] When the air exhaust device is started, the second cylinder synchronously drives the lower clamp to push the upper and lower glass half blanks together, and the expanded edge is pressed and combined by high temperature to form a sealed cavity to realize the synchronous operation of vacuumizing, air-filling and fusion. After fusion, the electric telescopic rod moves reversely to pull out the metal plug-in plate, and the inert gas needs to be continuously injected and the sealing plate still abuts against the inner recess of the glass during this period;

[0035] Then, the electric push rod drives the lower clamp to release the lower concave glass half blank, and the roller continues to press to promote the alignment and heat fusion of the protruding strips and the recessed grooves of the upper and lower half blanks, and finally obtain the hollow glass brick filled with inert gas;

[0036] S9: Loosening, pushing and feeding treatment;

[0037] After the upper clamp releases the hollow glass brick to the lower clamp, the second cylinder drives it to descend to be flush with the fusion platform. Immediately, the third cylinder on the support frame drives the clamping assembly to push it out of the lower clamp, and continuously pushes it through the feeding port to the output conveying device to complete the finished product conveying;

[0038] S10: Annealing;

[0039] The hollow glass brick conveyed by the output conveying device enters the annealing furnace and is slowly cooled under a controlled temperature curve to eliminate internal stress, prevent cracking, and improve its mechanical strength and thermal stability;

[0040] S11: Cooling and inspection;

[0041] The hollow glass brick after annealing is cooled to room temperature, and then strict quality inspection is carried out, including appearance, dimensional accuracy and impact resistance performance test, to ensure that the product meets the established quality standards;

[0042] S12: Packaging;

[0043] The hollow glass brick that passes the quality detection will be cleaned, stacked and properly packaged for convenient transportation and storage.

[0044] In summary, the present application has the following beneficial effects:

[0045] 1. In the process of hollow glass brick welding, first, the upper concave glass half blank and the lower concave glass half blank are clamped and positioned by the upper clamp and the lower clamp respectively, and under the driving action of the power device, the upper concave glass half blank and the lower concave glass half blank are pressed together, and before pressing, two metal inserts are inserted into the joint between the upper clamp and the lower clamp, and through the vacuum pumping device and the gas supply device connected to the air hole and the gas hole in the metal insert, the operation of vacuum pumping and gas injection is realized, while clamping the two glass bricks, based on the sealing assembly and through mechanical linkage, the upper clamp and the lower clamp form a local sealed microenvironment on the wall surface of the hollow glass brick; the vacuum inside the vacuum cavity and the filling of inert gas can be completed synchronously at the moment of welding combination of the upper concave glass half blank and the lower concave glass half blank, and the long-term stable sealing of the internal environment of the vacuum cavity is realized, thereby simplifying the production process and improving the functionality of the glass brick.

[0046] 2. By synchronously driving the two electric push rods, the two groups of special-shaped plates are relatively rotated on the fixed block around the center axis of the rotating shaft, so that the fixed clamping shaft at the bottom of the special-shaped plate moves relatively and pushes the upper concave glass half blank, so that the upper concave glass half blank is positioned and centered, and with the continuous relative movement of the clamping shaft, the clamping groove on the clamping shaft is positioned and clamped on the flared edge of the upper concave glass half blank; thereby realizing the automatic centering and accurate clamping of the glass half blank.

[0047] 3. Further, the roller shaft arranged on the lower clamp plays a crucial role in the clamping and disengaging process between the lower concave glass half blank and the lower clamp. On the one hand, it helps to disengage the lower concave glass half blank, and on the other hand, with the continuous advancement of the electric push rod on the lower clamp, the roller shaft moves upward and continuously presses the bottom of the lower concave glass half blank, thereby merging and welding the upper concave glass half blank and the lower concave glass half blank, ensuring the stability and precision of the merged and welded glass after the following vacuum pumping and gas filling steps. On the other hand, during the following process of loading the lower concave glass half blank on the conveying belt, the rotation angle of the special-shaped plate is adjusted by the electric push rod, so that the top surface of the roller shaft is higher than the top surface of the clamping shaft, and the rotatable arrangement of the roller shaft can effectively guide the lower concave glass half blank and reduce the wear of the lower concave glass half blank.

[0048] 4. When the electric telescopic rod drives the insertion block and the metal insertion plate towards the joint, the insertion block moves towards the L-shaped block, at this time, the curved connecting pipe is compressed, the air inside is squeezed into the sealing cavity in the high-temperature sealing capsule, the internal volume of the sealing cavity increases, and under the directional movement of the folding skeleton, the sealing plate abuts against the concave part of the hollow glass brick, so as to realize the synchronous movement of the metal insertion plate and the sealing plate, so as to realize vacuumizing, gas injection and sealing at the same time, and the deeper the metal insertion plate is inserted, the better the air extraction effect is, at the same time, the greater the pressure of the sealing plate on the hollow glass brick is, so the sealing effect is better;

[0049] On the contrary, when the electric telescopic rod moves reversely, when the metal insertion plate is separated from the hollow glass brick joint and realizes fusion, the inside of the curved connecting pipe is under negative pressure and attracts the air in the sealing cavity in the high-temperature sealing capsule; so that the high-temperature sealing capsule is compressed, and under the action of the folding skeleton, the reset action is realized.

[0050] 5. The metal insertion plate with the shaped groove and the shaped strip preforms the complementary convex strip and the recessed groove on the upper concave glass half blank and the lower concave glass half blank, greatly improving the accuracy of the final upper concave glass half blank and lower concave glass half blank alignment; and after the metal insertion plate is pulled out, the shaped groove and the shaped strip form a corrugated fusion joint on the two opposite sides of the hollow glass brick; the corrugated fusion joint means that the actual bonding interface length and the contact area are much larger than the straight line connection; the larger contact area means more intermolecular forces, thereby significantly improving the strength of the fusion; in addition, the corrugated structure helps to disperse the stress that may be generated on the fusion joint to a longer curve, avoiding stress concentration at a certain point, thereby enhancing the toughness and crack resistance of the joint.

[0062] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0063] This invention discloses a welding machine and process for processing hollow glass bricks, used to process and weld hollow glass bricks 1, such as... Figure 1 As shown, it is worth noting that the hollow glass brick 1 is composed of two symmetrical upper concave glass half blanks 101 and lower concave glass half blanks 102. After being precisely joined and fused together, a sealed vacuum cavity 103 will be formed between the upper concave glass half blank 101 and the lower concave glass half blank 102.

[0064] The hollow glass brick 1 is concave in the middle and forms an inner recess 104 in the middle and flared edge portions 105 on both sides. Specifically, the cross-sectional size of the flared edge portions 105 of the hollow glass brick 1 is larger than that of the inner recess 104 of the hollow glass brick 1, and the surface of the flared edge portions 105 of the hollow glass brick 1 is provided with die cast patterns 106 for the purpose of balancing the light transmittance and the decorative effect.

[0065] Specifically, a hollow glass brick 1 processing welding machine comprises a support frame 2 and a welding platform 3 fixed in the support frame 2, as shown in Figure 2 and Figure 3 The top of the support frame 2 is fixedly installed with a top plate 4, and the top plate 4 is provided with a first air cylinder 5. The bottom output of the first air cylinder 5 is connected with an upper clamp 6 for positioning and holding the upper concave glass half 101. A positioning groove 7 is formed in the center of the welding platform 3 and located in the area directly below the first air cylinder 5. The inside of the positioning groove 7 is fixedly installed with a second air cylinder 8, and the top output end of the second air cylinder 8 is connected with a lower clamp 9 for positioning and holding the lower concave glass half 102. When welding is needed, the first air cylinder 5 moves downward, and the upper clamp 6 at the bottom output of the first air cylinder 5 moves downward with the preheated upper concave glass half 101 in a molten state. At the same time, the second air cylinder 8 moves upward, and the lower clamp 9 at the top of the second air cylinder 8 moves upward with the lower concave glass half 102.

[0066] As shown in Figure 2 and Figure 3 The coordinated action of the first air cylinder 5 and the second air cylinder 8 makes the upper concave glass half 101 and the lower concave glass half on the upper clamp 6 and the lower clamp 9 gradually close, and finally makes them in a predetermined contact position, ensuring that the molten edges can be accurately aligned.

[0067] As shown in Figure 2 and Figure 3 Once the molten end faces of the upper concave glass half 101 and the lower concave glass half come into contact, the first air cylinder 5 and the second air cylinder 8 will not stop moving. The first air cylinder 5 and the second air cylinder 8 will continue to output force according to the pre-set pressure value, and apply a certain pressure to the glass half that has been in contact. This continuous pressure will promote the molten glass material to fully fuse, fill the tiny gaps, and expel the possible bubbles, forming a dense welding layer. The size and duration of the pressure are key parameters to ensure the quality of the welding, which are realized through precise control of the first air cylinder 5 and the second air cylinder 8.

[0068] As shown in Figure 4 and Figure 5As shown, further, the upper clamp 6 and the lower clamp 9 are of the same structure, the upper clamp 6 comprises a pressing plate 601, the middle part of the pressing plate 601 is bolted between the output end of the first air cylinder 5 through a thickened steel plate 602, the two ends of the pressing plate 601 are symmetrically bent upwards and form bent parts 603, the inside of the pressing plate 601 is symmetrically provided with two electric push rods 604, the corners of the pressing plate 601 are symmetrically provided with two fixed blocks 605, the bottom of the fixed block 605 is rotatably connected with a special-shaped plate 607 through a rotating shaft 606, the output end of the electric push rod 604 is hinged to the upper surface of the special-shaped plate 607, the middle part of the cross section of the special-shaped plate 607 forms a 135° obtuse angle, the bottom of the special-shaped plate 607 is fixedly installed with a clamping shaft 608, the inner surface of the clamping shaft 608 is provided with a clamping groove 609 matched with the flared edge part 105 of the upper concave glass half-billet 101.

[0069] As shown in Figure 4 and Figure 5 , the two electric push rods 604 synchronously output power, and their output ends are hinged to the upper surfaces of the two groups of special-shaped plates 607. Since the bottom of the special-shaped plate 607 is connected with the fixed block 605 through the rotating shaft 606, the linear thrust of the electric push rod 604 is converted into the rotary motion of the special-shaped plate 607 around the rotating shaft 606. When the electric push rod 604 is synchronously pushed, the two groups of special-shaped plates 607 will produce relative internal rotation on the fixed block 605 around the central axis of the rotating shaft 606.

[0070] As shown in Figure 4 and Figure 5 , the clamping shaft 608 fixed at the bottom of the special-shaped plate 607 will relatively move to the central area with the internal rotation of the special-shaped plate 607. This inward gathering motion will first contact the outer edge of the upper concave glass half-billet 101 and exert a guiding force on it, so that it is pushed to the geometric center of the clamp to realize accurate positioning and centering.

[0071] As shown in Figure 4 and Figure 5 , with the continuous internal movement of the clamping shaft 608, the clamping groove 609 on the inner surface of the clamping shaft 608, which is pre-set to be accurately matched with the shape of the flared edge part 105 of the upper concave glass half-billet 101, will finally accurately clamp and tightly hold the flared edge part 105 of the glass half-billet, thereby completing the stable clamping.

[0072] As shown in Figure 4 and Figure 5As shown, by the synchronous driving of the two electric push rods 604, in combination with the rotation of the special-shaped plate 607 and the inward movement of the clamping shaft 608, the glass semi-rough can be accurately and stably positioned to the center of the clamp, which is crucial for the accuracy of subsequent processing. The clamping groove 609 on the inner surface of the clamping shaft 608 precisely matches the shape of the flared edge part 105 of the glass semi-rough, providing a large area and uniform contact and clamping, effectively preventing the glass semi-rough from loosening or shifting during processing.

[0073] As shown in Figure 4 and Figure 5 , the opening cross-sectional size of the clamping groove 609 is larger than its own groove bottom cross-sectional size, and the wide opening can more easily guide the flared edge part 105 of the glass semi-rough into the clamping groove 609, improving the alignment efficiency. Once it enters, with the continuous movement of the clamping shaft 608, the flared edge part 105 will be further pushed into and tightly fit with the inner wall of the clamping groove 609, achieving accurate radial and axial positioning. When the flared edge part 105 of the upper concave glass semi-rough 101 enters and is pressed into such a clamping groove 609, the flared edge part 105 will be locked inside the clamping groove 609 due to the width of the groove bottom being smaller than the slot. This forms a mechanical interlocking structure, greatly improving the stability of clamping, preventing the glass semi-rough from accidentally falling off or loosening during processing due to vibration, external force or its own gravity. Since the flared edge part 105 of the glass is caught by the barb part of the clamping groove 609, the glass semi-rough is not easy to be pulled out vertically from the clamp, which is crucial for applications that need to withstand upward pulling force or need to ensure that it does not fall off in any posture.

[0074] As shown in Figure 4 and Figure 5 , when the flared edge of the glass semi-rough enters the clamping groove 609 with a wider opening and is pressed into the narrower part of the groove bottom, the flared part of the glass is clamped inside the clamping groove 609, and its geometry makes it impossible to slide out directly in the vertical direction.

[0075] As shown in Figure 4 and Figure 5 , the contact surface between the inner wall of the clamping groove 609 and the flared edge is beveled, and the clamping force is transmitted through these bevels. This beveled force not only provides radial clamping force, but also generates a downward component, which helps to stably fix the glass semi-rough in the clamp and prevent it from floating or shaking.

[0076] In summary, the design of the clamping groove 609 with a large opening and a small groove bottom is to take advantage of the special shape of the flared edge of the glass semi-rough, and to achieve more stable, safer and more accurate clamping of fragile glass products by forming a mechanical interlocking of barb or dovetail type.

[0077] As shown in Figure 4 and Figure 5As shown, secondly, the top of the special-shaped plate 607 is provided with a roller 6010. When the upper concave glass half 101 is fixed on the clamping shaft 608, the roller 6010 is in a non-contact state with the upper concave glass half 101 and is located directly above the upper concave glass half 101. The reverse driving of the electric push rod 604 causes the upper concave glass half 101 to be separated from the clamping groove 609 on the roller 6010. At this time, the roller 6010 moves towards the upper surface of the upper concave glass half 101 until it is in contact with the upper concave glass half 101 and exerts pressure thereon, thereby assisting the separation of the upper concave glass half 101.

[0078] It is worth further explaining that when the upper concave glass half 101 is separated from the clamping groove 609, the electric push rod 604 is reversely driven to preliminarily separate the upper concave glass half 101. At this time, the roller 6010 moves downward from the non-contact state, actively approaches and contacts the upper surface of the upper concave glass half 101, and exerts pressure thereon. This utilizes the rotatability and pressure exerting capability of the roller 6010 to assist the separation in a smooth and controlled manner.

[0079] The roller 6010 effectively assists the smooth and successful separation of the upper concave glass half 101 from the clamping groove 609 through contact and pressure exertion, thereby avoiding damage caused by jamming or improper operation.

[0080] Similarly to the principle of separating the upper concave glass half 101, the roller 6010 also plays an assisting role here by contacting and exerting pressure to help the lower concave glass half 102 separate from the clamped state. This ensures the smoothness of the lower concave glass half 102 during the separation process and reduces potential damage. Under the premise that the first air cylinder 5 and the second air cylinder 8 are not driven, the roller 6010 is driven to move upward through the continuous advancement of the electric push rod 604 on the lower clamp 9. The roller 6010 continuously exerts pressure on the bottom of the lower concave glass half 102, pushes the lower concave glass half 102 upward, and makes the lower concave glass half 102 accurately align with and tightly contact the upper concave glass half 101, thereby realizing the merging and fusion. The continuous and controlled pressure exerted by the roller 6010 ensures the stability of the merging and fusion of the upper and lower concave glass halves 102 and the accuracy of the alignment, thereby ensuring the fusion quality, which is crucial for the subsequent vacuum extraction and inflation steps and can ensure the sealing and performance of the final product.

[0081] The rotation angle of the special-shaped plate 607 is adjusted by the electric push rod 604, so that the top section of the roller 6010 is higher than the top section of the clamping shaft 608. The rotatable arrangement of the roller 6010 enables it to smoothly guide the lower concave glass half 102.

[0082] The roller 6010 can effectively guide the concave glass half 102 to enter the conveying belt accurately and smoothly, avoiding position deviation. The rotatability of the roller 6010 makes the glass half mainly roll in the guiding process, significantly reducing the friction and potential wear of the concave glass half 102, protecting the integrity of the product.

[0083] In summary, the roller 6010 greatly improves the efficiency, stability and product yield of the automatic production line in the key links of glass half separation, merging and welding, and feeding guidance, while effectively reducing the damage to the glass half during processing.

[0084] As shown in Figure 4 and Figure 5 , the axial surface of the shaft 608 is fixedly installed with an L-shaped block 10, the vertical axis of the L-shaped block 10 passes through the center line of the shaft 608 and coincides with the center axis of the clamping groove 609, and the inside of the L-shaped block 10 is provided with a metal plug plate 11 along the transverse axis. After the upper clamp 6 clamps the upper concave glass half 101, the metal plug plate 11 is located at the bottom of the upper concave glass half 101, which is used for further positioning and reinforcing the upper concave glass half 101, and during the alignment of the upper concave glass half 101 and the lower concave glass half 102, the metal plug plate 11 is located at the joint between the upper concave glass half 101 and the lower concave glass half 102 and penetrates into the inside of the vacuum cavity 103.

[0085] As shown in Figure 5 and Figure 6 , the pressing plate 601 is fixedly installed with an air extraction device 12 and a gas supply device 13 for introducing inert gas, and the air extraction device 12 and the gas supply device 13 are fixed on the bent portions 603 at both ends of the pressing plate 601.

[0086] As shown in Figure 5 and Figure 6 , specifically, the inside of the metal plug plate 11 is provided with a plurality of gas filling holes 16 for flushing inert gas into the vacuum cavity 103, the inside of the gas filling hole 16 is provided with a first micro electromagnetic valve, and the gas filling hole 16 and the gas supply device 13 are communicated through a flexible gas supply pipe 15. The inside of the other metal plug plate 11 is provided with a plurality of air extraction holes for extracting air in the vacuum cavity 103, and the air extraction holes and the air extraction device 12 are communicated through a flexible air extraction pipe 14.

[0087] As shown in Figure 5 and Figure 6As shown, when two oppositely arranged metal inserts 11 are located at the joint between the upper concave glass half 101 and the lower concave glass half 102 and are inserted into the interior of the vacuum cavity 103, first start the air extraction device 12 to extract the air in the vacuum cavity 103, then turn off the air extraction device 12, open the first micro electromagnetic valve, and start the gas supply device 13 to inject inert gas into the interior of the vacuum cavity 103. Thus, the vacuum extraction or inert gas filling in the cavity can be completed simultaneously at the moment of the fusion bonding of the upper concave glass half 101 and the lower concave glass half 102, and the long-term stable sealing of the internal environment of the cavity is achieved, thereby simplifying the production process and improving the functionality of the glass brick.

[0088] The vacuum extraction and injection points are arranged on the opposite sides of the vacuum cavity 103 of the hollow glass brick 1, so that a push-pull type airflow can be formed to ensure that the air in the cavity is more thoroughly and effectively extracted and completely replaced by inert gas. This can more effectively eliminate dead angles and residual air than single-point air extraction or injection, and ensure the purity and uniformity of the internal inert gas filling.

[0089] Specifically, the L-shaped block 10 and the internal metal inserts 11 are first used to accurately fix and position the upper concave glass half 101, so that it can be accurately aligned with the lower concave glass half 102. During the alignment of the upper concave glass half 101 and the lower concave glass half 102, two oppositely arranged metal inserts 11; one for air extraction and one for air injection; will be inserted into the joint of the vacuum cavity 103 to be formed or being formed. Before or at the initial stage of glass fusion, the air extraction device 12 connected to one of the metal inserts 11 is started. Through the air extraction hole in the metal insert 11, the air in the glass brick cavity is rapidly extracted to form a vacuum or near-vacuum state. After the vacuum extraction is completed, the air extraction device 12 is turned off. Then, the first micro electromagnetic valve connected to the air injection hole 16 in the other metal insert 11 is opened, and the gas supply device 13 is started. The inert gas is delivered to the metal insert 11 through the flexible gas supply pipe 15, and then injected into the vacuum cavity 103 through the air injection hole 16 to replace the original air.

[0090] Traditionally, the vacuum extraction or gas filling of a glass brick may need to be performed in a separate process or a complex sealed cabin. However, the device integrates and synchronizes these key steps with the glass fusion process. This means that at the moment when the glass halves are combined into a complete glass brick, the internal environment is also simultaneously processed. This reduces the need for additional equipment and operation steps, improves production efficiency, and reduces production costs.

[0091] As shown in FIG. 6, the glass brick 1 is formed by the fusion bonding of the upper concave glass half 101 and the lower concave glass half 102. The L-shaped block 10 and the internal metal inserts 11 are used to accurately fix and position the upper concave glass half 101, so that it can be accurately aligned with the lower concave glass half 102. During the alignment of the upper concave glass half 101 and the lower concave glass half 102, two oppositely arranged metal inserts 11; one for air extraction and one for air injection; will be inserted into the joint of the vacuum cavity 103 to be formed or being formed. Before or at the initial stage of glass fusion, the air extraction device 12 connected to one of the metal inserts 11 is started. Through the air extraction hole in the metal insert 11, the air in the glass brick cavity is rapidly extracted to form a vacuum or near-vacuum state. After the vacuum extraction is completed, the air extraction device 12 is turned off. Then, the first micro electromagnetic valve connected to the air injection hole 16 in the other metal insert 11 is opened, and the gas supply device 13 is started. The inert gas is delivered to the metal insert 11 through the flexible gas supply pipe 15, and then injected into the vacuum cavity 103 through the air injection hole 16 to replace the original air. Figure 5As shown, the inside of the L-shaped block 10 is provided with a limiting hole for the metal plug-in plate 11 to pass through and slide, one end of the metal plug-in plate 11 is towards the hollow glass brick 1, the other end of the metal plug-in plate 11 is fixedly installed with an insertion block 17, the insertion block 17 is provided between the outer wall of the L-shaped block 10 and the electric telescopic rod 18, the electric telescopic rod 18 is fixed on the outer wall of the L-shaped block 10, and the output end of the electric telescopic rod 18 is connected to the insertion block 17, through the electric telescopic rod 18, the insertion block 17 drives the metal plug-in plate 11 to slide inside the limiting hole, after the metal plug-in plate 11 is vacuumized and aerated, the metal plug-in plate 11 is separated from the vacuum cavity 103 through the electric telescopic rod 18.

[0092] As shown in the figure, Figure 6 As shown, the upper surface of the metal plug-in plate 11 is provided with a plurality of shaped grooves 19 at equal intervals, and the lower surface of the metal plug-in plate 11 is provided with a plurality of shaped strips 20 matched with the shaped grooves 19, it is worth noting that the upper surface of the metal plug-in plate 11 is in contact with the lower surface of the upper concave glass half blank 101 at the joint, and under the action of pressure and preheating, a plurality of raised strips can be formed at the joint of the lower surface of the upper concave glass half blank 101, and when the lower surface of the metal plate is in contact with the upper surface of the lower concave glass half blank 102 at the joint, a plurality of recessed grooves matched with the raised strips can be formed at the joint of the upper surface of the lower concave glass half blank 102 under the action of pressure and preheating, after the metal plug-in plate 11 is separated from the vacuum cavity 103, the raised strips on the upper concave glass half blank 101 are aligned with the recessed grooves on the lower concave glass half blank 102 by continuously pressing the upper concave glass half blank 101 and the lower concave glass half blank 102, and the raised strips on the upper concave glass half blank 101 are fused and formed into a fusion joint; This step ensures that the upper concave glass half blank 101 and the lower concave glass half blank 102 have complementary, accurately aligned geometric structures at the joint.

[0093] As shown in the figure, Figure 7 As shown, by preforming complementary raised strips and recessed grooves on the two upper concave glass half blanks 101 and the lower concave glass half blank 102, the accuracy of the final alignment of the upper concave glass half blank 101 and the lower concave glass half blank 102 is greatly improved. In addition, traditional simple plane fusion or bonding may not achieve the desired strength and air tightness. However, this preformed fusion method can form a physically continuous and chemically uniform fusion joint by increasing the effective contact area of the joint and ensuring sufficient mutual melting of the materials, thereby providing high joint strength and excellent air tightness to effectively prevent leakage. Moreover, compared with simple plane butt joint, the fusion joint with complex occlusion structure can help to more evenly distribute the stress at the joint, thereby reducing stress concentration points and improving the durability of the product under thermal cycling or mechanical stress.

[0094] As shown in the figure, Figure 8As shown, the cross section of the forming groove 19 matches the cross section of the forming strip 20, and the cross section of the forming groove 19 is a semicircular structure, which ensures close fitting and effective stress transfer during bonding. The protruding strips on the upper concave glass half 101 are aligned with the recessed grooves on the lower concave glass half 102 and are hot melted, forming corrugated fusion seams; the corrugated fusion seams mean that the actual bonding interface length and contact area are much larger than that of a straight line connection. A larger contact area means more intermolecular forces, thereby significantly improving the strength of the fusion. In addition, the corrugated structure helps to disperse the stress that may occur at the joint to a longer curve, avoiding stress concentration at a certain point, thereby enhancing the toughness and crack resistance of the joint.

[0095] The metal insert plate 11 is made of austenitic stainless steel with high temperature resistance, specifically, the austenitic stainless steel contains a high content of nickel and chromium, which has good oxidation resistance and creep strength at high temperatures. 310S stainless steel is particularly suitable for continuous use at temperatures of 900-1150°C, and the surface of the metal insert plate 11 is sprayed with a release coating, specifically, the release coating is a boron nitride coating, the thickness of the boron nitride coating is 0.05-0.1 millimeters; boron nitride is an excellent high-temperature lubricant and release agent, especially suitable for glass and metal melts. It has extremely high heat resistance (more than 2000°C in an inert atmosphere, about 1000°C in an oxidizing atmosphere) and excellent non-wetting properties; thereby preventing hot-melt glass from adhering to the surface of the metal insert plate 11 during cooling or extraction. Thus reducing surface defects and damage caused by the adhesion of glass raw materials to the metal insert plate 11, ensuring the integrity and aesthetics of the hot-melt glass product.

[0096] Further, the L-shaped block 10 is fixed with a sealing assembly 21 on one side of the inner concave portion 104 of the hollow glass brick 1, and the sealing assembly 21 is symmetrically arranged about the center axis of the metal insert plate 11. During the vacuum-filling process of the metal insert plate 11, the sealing assembly 21 is used to form a local sealed microenvironment near the metal insert plate 11 and at the joint between the upper concave glass half 101 and the lower concave glass half 102.

[0097] Specifically, the sealing assembly 21 includes a rectangular plate 2101 and a sealing plate 2102, one side of the rectangular plate 2101 is fixedly connected with the L-shaped block 10, the other side of the rectangular plate 2101 is provided with a folding framework with a reset function between the other side of the rectangular plate 2101 and one side of the sealing plate 2102, the outside of the folding framework is provided with a high-temperature-resistant sealing capsule 2103, the high-temperature-resistant sealing capsule 2103 is sealingly connected to the rectangular plate 2101 and the sealing plate 2102, the other side of the sealing plate 2102 is attached to the outer wall of the inner recess 104 of the hollow glass brick 1, the folding framework is arranged to support and connect the rectangular plate 2101 and the sealing plate 2102, and can have a self-resetting function, and under the effect of extension, the spacing between the sealing plate 2102 and the rectangular plate 2101 is extended and changed, so that the sealing plate 2102 abuts against the outer wall of the inner recess 104 of the hollow glass brick 1, and under the overall effect of the high-temperature-resistant sealing capsule 2103, a locally sealed micro-environment is formed.

[0098] Specifically, the rectangular plate 2101 is first fixedly and stably connected to the L-shaped block 10, providing a solid foundation for the entire sealing assembly 21. The rectangular plate 2101 and the sealing plate 2102 are connected by the folding framework, which is not as fixed as rigid connection. This folding framework has a reset function and an extension effect. When sealing is needed, the folding framework can extend and change the spacing between the rectangular plate 2101 and the sealing plate 2102 through its extensibility. This extension allows the sealing plate 2102 to extend outward and tightly abut against the outer wall of the inner recess 104 of the hollow glass brick 1. When the sealing plate 2102 tightly abuts against the inner wall of the glass brick, the entire body formed by the sealing plate 2102, the high-temperature-resistant sealing capsule 2103, and the rectangular plate 2101, together with the L-shaped block 10 and possibly the metal insert plate 11, encloses a micro-space. This micro-space is the desired locally sealed micro-environment, which precisely surrounds the joint between the upper concave glass half 101 and the lower concave glass half 102 near the metal insert plate 11.

[0099] After the vacuum-filling process is completed, the reset function of the folding framework allows it to automatically or through external force return to the initial state, allowing the sealing plate 2102 to be separated from the inner wall of the glass brick, facilitating subsequent operations or removal.

[0100] In short, by using a folding mechanism with extension and self-resetting capabilities, the sealing plate 2102 is actively pressed against the target surface, creating a controlled locally sealed area. Performing vacuum and inflation in a smaller, controlled micro-environment allows for more precise control of environmental parameters, ensuring the quality of the joint sealing.

[0101] As Figure 8 and Figure 8As shown, further synergy, high-temperature-resistant sealing capsule 2103, rectangular plate 2101 and sealing plate 2102 form a sealed cavity, rectangular plate 2101 is provided with a connecting hole, the connecting hole is in communication with the sealed cavity in the high-temperature-resistant sealing capsule 2103, and the connecting hole of the rectangular plate 2101 is connected with the insertion block 17 through the foldable bend connecting pipe 2104. When the electric telescopic rod 18 drives the insertion block 17 and the metal plug-in plate 11 to move forward and approach the L-shaped block, the foldable bend connecting pipe 2104 connecting the insertion block 17 and the rectangular plate 2101 is compressed. The air (or gas) in the bend connecting pipe 2104 is extruded into the sealed cavity formed by the high-temperature-resistant sealing capsule 2103, the rectangular plate 2101 and the sealing plate 2102. The increase in the amount of gas in the sealed cavity causes the internal volume of the sealing capsule to increase and generates an expansion pressure outward. The expansion of the sealing capsule acts on the folding framework, which converts the expansion force into a precise directional movement of the sealing plate 2102. The sealing plate 2102 tightly abuts against the inner recess 104 of the hollow glass brick 1 under the guidance of the folding framework, thereby achieving sealing.

[0102] The above process is synchronized with the insertion of the metal plug-in plate 11; the deeper the metal plug-in plate 11 is inserted, the more fully the bend connecting pipe 2104 is compressed, the more air is extruded into the sealed cavity, and the greater the pressure exerted by the sealing plate 2102 on the hollow glass brick 1, and the better the sealing effect. The sealing pressure and the air extraction effect are positively correlated with the insertion depth of the metal plug-in plate 11. This means that the system can automatically adjust the tightness of the sealing and the strength of the air extraction according to actual needs, ensuring that each operation can achieve the best effect.

[0103] When the electric telescopic rod 18 moves in reverse, the metal plug-in plate 11 is pulled away from the joint, and the bend connecting pipe 2104 is no longer compressed, and a negative pressure is generated inside it. This negative pressure will attract the air in the sealed cavity of the high-temperature-resistant sealing capsule back into the bend connecting pipe 2104. The high-temperature-resistant sealing capsule loses internal pressure and is compressed under the action of high external pressure. The folding framework again plays a role in guiding the sealing plate 2102 to return to its original position as the sealing capsule is compressed, preparing for the next operation. The insertion, sealing, vacuuming and gas injection of the metal plug-in plate 11 are carried out simultaneously. This integrated design greatly improves work efficiency and reduces the number of operation steps.

[0104] It also includes a heating assembly arranged on the upper side of the fusion platform 3. The heating assembly is a ring-shaped induction heater that surrounds the joint area of the upper clamp 6 and the lower clamp 9 to achieve local preheating.

[0105] Also included is a third cylinder 23 disposed on the support frame 2 and used to drive in the horizontal direction, the output end of the third cylinder 23 being connected with a clamping assembly 24, the clamping assembly 24 being used to clamp the upper concave glass half blank 101, the lower concave glass half blank 102 and the final hollow glass brick, and a drive rotating shaft being disposed between the clamping assembly 24 and the output end of the third cylinder 23, used to realize a 180° flip between the clamping assembly 24 and the output end of the third cylinder 23, specifically, through the third cylinder 23, the clamping assembly 24 connected with the output end of the third cylinder 23 is moved towards the hollow glass brick 1 direction until the hollow glass brick 1 falls into the inside of the clamping assembly 24 and clamps the upper and lower surfaces of the hollow glass brick 1 through the clamping assembly 24.

[0106] In addition, through the third cylinder 23, the clamping assembly 24 connected with the output end of the third cylinder 23 is moved towards the upper concave glass half blank 101 and the lower concave glass half blank 102 direction, and the clamping assembly 24 is flipped 180° through the drive rotating shaft, so that the clamping assembly 24 is in a horizontal state and is clamped horizontally on the flared edge part 105 of the upper concave glass half blank 101 and the lower concave glass half blank 102, and the front and back positions of the upper concave glass half blank 101 and the lower concave glass half blank 102 are adjusted through the third cylinder 23.

[0107] As shown in Figure 7 and Figure 8 Figure 9 Figure 10 , based on the above hollow glass brick 1 processing welding machine, the process of the hollow glass brick 1 processing welding machine, the processing steps include:

[0108] S1: raw material preparation and mixing:

[0109] Select high-quality glass raw materials, mainly including quartz sand, soda ash, limestone, feldspar, and add a small amount of other additives, and the glass raw materials are weighed and mixed according to the accurate formula ratio to ensure the uniformity of the glass composition;

[0110] S2: melting:

[0111] The mixed raw materials are sent into a high-temperature glass furnace, and at a temperature as high as about 1500-1600°C, the glass raw materials are completely melted to form clear and uniform glass liquid;

[0112] S3: press forming:

[0113] The molten glass liquid flows out of the furnace and is cut into glass drops of a certain weight and shape; and each drop is sent into a mold and pressed into a hollow glass brick 1 half by a press, and finally the upper concave glass half blank 101 and the lower concave glass half blank 102 with the same size are obtained;

[0114] S4: joint preheating treatment:

[0115] The just-formed upper concave glass half 101 and lower concave glass half 102 are still in a high-temperature state, and the upper concave glass half 101 and lower concave glass half 102 are placed on the input conveying device 22 by the transfer device in an alternating manner, for continuously conveying the upper concave glass half 101 and lower concave glass half 102 to the fusion platform 3, and during the operation of the input conveying device 22, the inner concave portions 104 of the upper concave glass half 101 and lower concave glass half 102 are preheated by the heating device on the input conveying device 22;

[0116] S5: positioning and clamping:

[0117] T1: positioning and clamping of the upper concave glass half 101;

[0118] The height of the lower clamp 9 is adjusted by the second air cylinder 8, so that the top surface of the roller shaft 6010 on the lower clamp 9 is lower than the top surface of the clamping shaft 608, the rolling of the roller shaft 6010 is used to guide the upper concave glass half 101 on the input conveying device 22, and the area between the two clamping shafts 608 defines the position of the upper concave glass half 101, so as to position the upper concave glass half 101 left and right, and adjust the clamping assembly 24 to a horizontal state, so that the clamping assembly 24 clamps the flared edge portion 105 of the upper concave glass half 101 and lower concave glass half 102 horizontally, and the front and rear positions of the upper concave glass half 101 are adjusted by the infrared positioning assembly on the clamping assembly 24 and the third air cylinder 23, so as to position the upper concave glass half 101 front and rear; therefore, the upper concave glass half 101 is quickly positioned by the lower clamp 9 and the clamping assembly 24;

[0119] The height of the upper clamp 6 is adjusted by the first air cylinder 5, so that the upper clamp 6 moves towards the positioned upper concave glass half 101, when the roller shaft 6010 on the upper clamp 6 abuts against the upper surface of the upper concave glass half 101, the special-shaped plate 607 is rotated around the rotating shaft 606 by driving the electric push rod 604, until the clamping groove 609 on the clamping shaft 608 clamps the flared edge portion 105 of the upper concave glass half 101, and the upper concave glass half 101 is quickly clamped by the upper clamp 6;

[0120] T2: positioning and clamping of the lower concave glass half 102;

[0121] Subsequently, the lower concave glass half 102 is continuously transferred by the input conveying device 22, at this time, the flared edge portion 105 on the lower concave glass half 102 faces downward, the front and rear positions of the lower concave glass half 102 are adjusted by the infrared positioning assembly and the third air cylinder 23, so as to position the lower concave glass half 102 front and rear, and the lower concave glass half 102 is positioned left and right by the roller shaft 6010 and clamping shaft 608 on the lower clamp 9;

[0122] By driving the electric push rod 604 on the lower clamp 9, the special-shaped plate 607 rotates around the rotating shaft 606 until the clamping groove 609 on the clamping shaft 608 is clamped on the flared edge part 105 of the lower concave glass half 102, and the lower concave glass half 102 is quickly clamped by the lower clamp 9;

[0123] It is worth noting that at this time, the upper concave glass half 101 and the lower concave glass half 102 are arranged in an up-down alignment;

[0124] S6: fusion pretreatment;

[0125] The second cylinder 8 is driven, so that the lower clamp 9 and the lower concave glass half 102 move upward and toward the upper concave glass half 101. When the joint between the lower concave glass half 102 and the upper concave glass half 101 is 1 cm, the heating assembly on the support frame 2 is used for local heating, so that the bottom of the inner concave part 104 of the upper concave glass half 101 and the top of the inner concave part 104 of the lower concave glass half 102 are in a hot fusion state; and the second cylinder 8 is continuously pushed until the lower concave glass half 102 contacts the upper concave glass half 101. At this time, the front and rear joints of the lower concave glass half 102 and the upper concave glass half 101 are first fused, and then the left and right joints are fused, until the vacuum cavity 103 is formed inside the lower concave glass half 102 and the upper concave glass half 101;

[0126] S7: vacuumizing and air charging treatment:

[0127] The insertion block 17 is moved toward the center of the upper concave glass half 101 by the electric telescopic rod 18 until the insertion block 17 with the metal insertion plate 11 is inserted into the 1 cm joint and penetrates into the vacuum cavity 103. At the same time, the bent connecting pipe 2104 is compressed, and the air inside is extruded into the sealing cavity in the high-temperature sealing capsule. The internal volume of the sealing cavity increases, and under the directional movement of the folding framework, the sealing plate 2102 abuts against the inner concave part 104 of the upper concave glass half 101 and the lower concave glass half 102. The upper and lower sealing assemblies 21 form a local sealing microenvironment at the joint;

[0128] Then the air in the vacuum cavity 103 is pumped out by starting the air pumping device 12, and then the air pumping device 12 is closed, the first micro electromagnetic valve is opened, and the air supply device 13 is started to inject inert gas into the inside of the vacuum cavity 103;

[0129] S8: fusion treatment;

[0130] At the same time of starting the air extraction device 12, the lower clamp 9 is driven upward by the second cylinder 8, so that the lower concave glass half blank 102 on the lower clamp 9 abuts against the upper concave glass half blank 101, and the lower concave glass half blank 102 and the upper concave glass half blank 101 are firmly fused by high-temperature welding and pressing, so as to form a closed vacuum cavity 103 for realizing synchronous operation of vacuumizing, inflating and welding;

[0131] After the lower concave glass half blank 102 and the upper concave glass half blank 101 are fused, the metal plug plate 11 is separated from the joint of the hollow glass brick 1 by reverse movement of the electric telescopic rod 18. It should be noted that when the metal plug plate 11 is completely separated from the hollow glass brick 1, the inert gas needs to be continuously injected and the sealing plate 2102 still abuts against the inner concave part 104 of the hollow glass brick 1;

[0132] Subsequently, the electric push rod 604 on the lower clamp 9 is driven, so that the clamping groove 609 on the clamping shaft 608 is separated from the lower concave glass half blank 102, the roller shaft 6010 moves upward and continuously presses the bottom of the lower concave glass half blank 102, so that the protruding strips formed by the upper concave glass half blank 101 and the recessed grooves formed by the lower concave glass half blank 102 are aligned and hot fused, and finally the hollow glass brick 1 filled with inert gas is obtained;

[0133] S9: loosening, pushing and feeding treatment;

[0135] T2: pushing: the third cylinder 23 on the support frame 2 is started, so that the clamping assembly 24 connected to the output end of the third cylinder 23 moves toward the hollow glass brick 1 until the hollow glass brick 1 falls into the inside of the clamping assembly 24, and the hollow glass brick 1 is pushed away from the lower clamp 9 by the third cylinder 23;

[0137] S10: annealing;

[0138] The hollow glass brick 1 delivered by the output delivery device 25 is sent to an annealing furnace and slowly cooled under a controlled temperature curve for eliminating the internal stresses of the glass, preventing the hollow glass brick 1 from cracking during use and improving its mechanical strength and thermal stability;

[0139] S11: cooling and inspection;

7. A process for a welding machine for processing hollow glass bricks (1), based on the welding machine for processing hollow glass bricks (1) as described in any one of claims 1-6, characterized in that, Its processing steps include: S1: Raw material preparation and mixing: To ensure the uniformity of the glass composition, the carefully selected core raw materials such as quartz sand, soda ash, limestone, and feldspar, as well as a small amount of additives, must be precisely weighed and thoroughly mixed according to the precise formula. S2: Melting: The mixed raw materials are fed into a high-temperature glass furnace and completely melted at a temperature of 1500-1600°C to obtain a clear and homogeneous glass melt. S3: Compression molding: After the molten glass is poured out of the furnace, it is cut into droplets of a specific weight and then pressed into a mold. The press then shapes the droplets into upper concave glass blanks (101) and lower concave glass blanks (102) of uniform size and aligned vertically. S4: Joint preheating treatment: The newly formed upper concave glass half blank (101) and lower concave glass half blank (102) are stacked on the preheating input conveying device (22) in an alternating pattern of positive and negative through the transfer equipment. During the process of conveying to the welding platform (3), the inner concave part (104) is preheated by the heating device on the conveying device. S5: Positioning and clamping: T1: Positioning and clamping of the upper concave glass half blank (101); The lower clamp (9) is guided by the roller (6010) and limited by the locking shaft (608) to achieve rapid and accurate positioning of the upper concave glass half blank (101); then, the upper clamp (6) is driven by the cylinder and electric push rod (604), and its slot (609) accurately engages the flared edge of the half blank to complete efficient clamping; T2: Positioning and clamping of concave glass half-form (102); Subsequently, the glass blank (102) with the flared edge facing down is quickly positioned by the roller (6010) and the clamping shaft (608) of the lower clamp (9) through continuous transfer via the input conveying device (22); then the shaped plate (607) of the lower clamp (9) is rotated by the electric push rod (604), and its slot (609) precisely engages with the flared edge of the blank to complete the rapid clamping. S6: Welding pretreatment; The second cylinder (8) is driven to move the lower clamp (9) upward with the lower concave glass half blank (102). When the distance between it and the upper concave glass half blank (101) is 1cm, the heating component on the support frame (2) locally heats the concave part (104) of both to a hot-melt state. The second cylinder (8) continues to advance until the lower concave glass half blank (102) and the upper concave glass half blank (101) come into contact. At this time, the front and rear seams of the lower concave glass half blank (102) and the upper concave glass half blank (101) are first fused together, and then fused together from side to side, until a vacuum cavity (103) is formed inside the lower concave glass half blank (102) and the upper concave glass half blank (101). S7: Vacuuming and inflation process: The electric telescopic rod (18) drives the insert block (17) to carry the metal insert plate (11) into the vacuum cavity (103) in the gap between the glass half blanks. At the same time, the bent connecting pipe (2104) is compressed, causing the sealed cavity to expand. The folded frame pushes the sealing plate (2102) to fit tightly against the concave part (104) of the glass, forming a local sealed microenvironment at the joint. Subsequently, the pumping device (12) empties the cavity, and the gas supply device (13) injects inert gas. S8: Welding process; When the vacuum equipment (12) is started, the second cylinder (8) synchronously drives the lower clamp (9) to push the upper and lower glass half blanks together. The flared edge is pressed together by high temperature welding to form a sealed cavity to realize the synchronous operation of vacuuming, gas filling and welding. After fusion, the electric telescopic rod (18) moves in the opposite direction to pull away the metal insert (11). During this period, inert gas needs to be continuously injected and the sealing plate (2102) still abuts against the concave part (104) of the glass. Subsequently, the electric push rod (604) drives the lower clamp (9) to release the concave glass half-bulb (102), while the roller (6010) continues to apply pressure to promote the alignment and heat fusion of the upper and lower half-bulb protrusions and the concave groove, and finally obtain the hollow glass brick (1) filled with inert gas. S9: Loosening, pushing and feeding processing; After the upper clamp (6) releases the hollow glass brick (1) to the lower clamp (9), the second cylinder (8) drives it to descend to be flush with the welding platform (3); then, the third cylinder (23) on the support frame (2) drives the clamping assembly (24) to push it out of the lower clamp (9) and continuously push it through the feeding port to the output conveying device (25) to complete the finished product conveying; S10: Annealing; Hollow glass bricks (1) conveyed by output conveyor (25) enter the annealing furnace and are slowly cooled under a controlled temperature curve to eliminate internal stress, prevent cracking, and improve their mechanical strength and thermal stability. S11: Cooling and Inspection; After annealing, the hollow glass bricks (1) are cooled to room temperature and then subjected to strict quality inspection, covering performance tests such as appearance, dimensional accuracy and impact resistance, to ensure that the products meet the established quality standards. S12: Packaging; Hollow glass bricks (1) that have passed quality inspection will be cleaned, stacked and properly packaged for transportation and storage.
