Description

Technical Field

[0001] The present invention relates to the technical field of hollow glass block processing, and particularly relates to a welding semi-finished product system for forming hollow glass blocks. Background Art

[0002] In the production process of hollow glass blocks, the welding process is a key link determining product quality and production efficiency. At present, hollow glass blocks are usually formed by welding two semi-finished products at high temperature. In the traditional welding method, when welding two groups of semi-finished products, there are obvious limitations. When welding the moving semi-finished products, the movement process of the semi-finished products must be paused, and the welding is carried out when the semi-finished products are in a static state. This operation mode that requires pausing the movement for welding greatly reduces the production efficiency. The pause on the production line not only reduces the number of hollow glass blocks produced per unit time, but also increases the idle time of the equipment and energy consumption. Therefore, a welding semi-finished product system for forming hollow glass blocks is proposed, which can complete the welding operation during the continuous movement of the semi-finished products and improve the production efficiency. Summary of the Invention

[0013] Advantages of the present invention: (1) For the welding semi-finished product system for forming hollow glass bricks of the present invention, the rotating cylinder drives the upper clamping die, the lower clamping die and the semi-finished product to continuously rotate, and heating and welding are completed during the movement. When the rotating cylinder rotates, the arc-shaped plate drives the upper clamping die and the lower clamping die to move, so that the semi-finished product sequentially passes through the heating and welding links without pause, greatly improving the production efficiency, increasing the output quantity of hollow glass bricks per unit time, and reducing the idle time of the equipment.

[0014] (2) The welding semi - blank system for forming hollow glass bricks according to the present invention, with the design of a flame - spraying heating plate, a square groove, and multiple groups of flame - spraying holes, in cooperation with an arc - shaped pipe with adjustable gas supply, can heat the semi - blank at specific positions. At the initial stage of heating, the arc - shaped pipe blocks the air supply holes, and the gas supply volume is low; as the arc - shaped pipe extends out of the arc - shaped positioning pipe, the blocking amount decreases, and the gas supply volume increases; after heating is completed, the arc - shaped positioning pipe resets, and the gas supply volume decreases, thereby reducing gas waste, improving energy utilization efficiency, ensuring uniform heating of the semi - blank, and enhancing the welding quality.

[0015] (3) The welding semi - blank system for forming hollow glass bricks according to the present invention can flexibly adjust the distance between the upper clamping die and the lower clamping die according to the thickness of the semi - blank. By driving the first gear to rotate, using the threaded connection between the threaded rod and the arc - shaped plate and the moving ring and the opposite thread rotation directions, the reverse movement of the moving ring and the arc - shaped plate is realized, and then the special - shaped track, the support roller, the lower clamping die, and the upper clamping die move up and down to match the processing requirements of semi - blanks with different thicknesses, enhancing the versatility and adaptability of the equipment.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] In order to complete the welding operation during the continuous movement of the semi-blank and improve the production efficiency, as an embodiment of the present invention, Figure 1 , Figure 2 As shown in the figure, a half-blank welding system for forming hollow glass bricks described in the present invention comprises a support platform 1, and a rotating drum 2 rotatably connected to the support platform 1 and vertically arranged, the outer side of the rotating drum 2 is vertically slidably connected to a plurality of groups of circumferentially distributed arc plates 3, an upper clamping die 4 is installed on the upper outer side of the arc plate 3, a lower clamping die 5 is vertically slidably connected to the lower outer side of the arc plate 3, a supporting roller 6 is installed on the lower part of the lower clamping die 5, a special-shaped track 7 rollingly connected to the supporting roller 6 is movably connected to the support platform 1, and a flame-spraying heating plate 8 is provided on the outer side of the rotating drum 2.

[0020] When in use, place the half blank of the hollow glass brick between the upper clamping mold 4 and the lower clamping mold 5, and the upper clamping mold 4 and the lower clamping mold 5 cooperate to initially fix the position of the half blank; start the equipment, drive the rotating drum 2 to start to rotate stably around the central axis of the support platform 1, and drive the arc plate 3, the upper clamping mold 4, and the lower clamping mold 5 to make a circular motion around the central axis of the rotating drum 2; When the rotating upper clamping die 4 and the lower clamping die 5 drive the semi-blank to move into the action range of the flame-spraying heating plate 8, the flame-spraying heating plate 8 is located between the upper clamping die 4 and the lower clamping die 5, and can heat the side of the semi-blank clamped by the upper clamping die 4 and the lower clamping die 5. During the continuous rotation of the drum 2, the semi-blank is continuously heated in the movement until it reaches the ideal processing temperature, so as to prepare for the subsequent welding operation; As the drum 2 continues to rotate, the support roller 6 rolls along the special-shaped track 7. When the support roller 6 moves to a specific position on the special-shaped track 7, it can drive the lower clamping mold 5 to slide upward. When the lower clamping mold 5 rises to a predetermined position, the half-blank on the lower clamping mold 5 and the half-blank on the upper clamping mold 4 are precisely docked and pressed into contact with each other. The two groups of half-blanks are quickly fused into one, and a hollow glass brick is successfully obtained. After the welding operation is completed, the lower clamp 5 continues to move and move downward along the predetermined path under the continuous guidance of the special-shaped track 7. When the glass brick moves to the pre-set designated position, the upper clamp 4 releases the clamping force on the half-blank, and the operator can easily take out the hollow glass brick for subsequent processing. At the same time, the continuous rotation of the drum 2 drives the next group of upper clamps 4 and lower clamps 5 with half-blanks to move to the welding position, and repeats the above series of operation steps to realize the continuous and efficient production of hollow glass bricks. There is no need to pause the movement of the half-blank, which effectively reduces the pause on the production line and increases the output of hollow glass bricks per unit time.

[0021] In order to facilitate the welding of the two sets of half blanks during the moving process, for example, Figure 1 , Figure 2 As shown, the present invention also includes that the special-shaped track 7 is annular, and a ramp 9 for assisting the lifting support roller 6 to move upward and downward is provided on the special-shaped track 7.

[0022] When in use, as the drum 2 rotates, the upper clamping die 4 and the lower clamping die 5 move while clamping the half-blank, and the flame-spraying heating plate 8 heats the side of the half-blank clamped by the upper clamping die 4 and the lower clamping die 5. During the continuous rotation of the drum 2, the half-blank is continuously heated and gradually reaches the ideal processing temperature. When the support roller 6 moves to the position where the ramp 9 is provided on the special-shaped track 7, the support roller 6 starts to move upward under the action of the ramp 9, and the support roller 6 drives the lower clamping mold 5 to slide upward. When the lower clamping mold 5 rises to a predetermined position, the half blank on the lower clamping mold 5 is butted against the half blank on the upper clamping mold 4 and pressed into contact with each other, and the two groups of half blanks are quickly fused into one, forming a hollow glass brick; After the welding operation is completed, as the drum 2 rotates, the support roller 6 moves down along the ramp 9 and drives the lower clamp 5 to separate from the upper clamp 4. The upper clamp 4 drives the welded glass bricks to continue to move along a predetermined path. When the glass bricks move to a predetermined designated position, the upper clamp 4 opens and the operator takes out the hollow glass bricks.

[0023] In order to ensure the consistency of the heating effect, for example, Figure 1 , Figure 3 , Figure 9 , Figure 10As shown, the present invention also includes that the flame-spraying heating plate 8 is located between the upper clamping die 4 and the lower clamping die 5, a square groove 10 is set through the upper part of the flame-spraying heating plate 8, and the upper edge and the lower edge of the square groove 10 are provided with a plurality of groups of flame-spraying holes 11, the interior of the flame-spraying heating plate 8 is a hollow structure connected with the flame-spraying holes 11, an arc-shaped positioning tube 12 is installed on the side of the flame-spraying heating plate 8 away from the rotating drum 2, and the inner wall of the arc-shaped positioning tube 12 is provided with an air supply hole 13 connected with the hollow structure, and an arc-shaped tube 14 is sealed and slidably connected inside the arc-shaped positioning tube 12, and the end of the arc-shaped tube 14 away from the arc-shaped positioning tube 12 is connected to the gas.

[0024] When in use, the gas source is connected to the end of the arc tube 14 away from the arc positioning tube 12, and as the rotating drum 2 drives the upper clamping die 4 and the lower clamping die 5 to rotate, the half-blank is moved into the range of action of the flame-spraying heating plate 8. At this time, the gas enters the hollow structure of the flame-spraying heating plate 8 from the arc tube 14 through the gas supply hole 13 on the inner wall of the arc positioning tube 12, and then sprays out from the several groups of flame-spraying holes 11 on the upper and lower edges of the square groove 10. After being sprayed out, the gas is ignited to form a flame, which heats the side of the half-blank clamped by the upper clamping die 4 and the lower clamping die 5. The design of the flame-spraying heating plate 8 being located between the upper clamping mold 4 and the lower clamping mold 5, combined with the structure of the square groove 10 and the multiple groups of flame-spraying holes 11, can accurately heat the half-blanks in a specific position, so that the sides of the half-blanks close to each other are evenly heated, thereby ensuring the consistency of the heating effect and improving the quality of the fusion of the hollow glass brick half-blanks; and by adjusting the position of the arc tube 14 in the arc positioning tube 12, the number of air supply holes 13 connected to the arc tube 14 can be adjusted, thereby adjusting the firepower of the flame-spraying holes 11, thereby adjusting the heating temperature of the flame-spraying heating plate 8 according to actual needs.

[0025] In order to automatically adjust the gas supply according to the processing conditions, for example, Figure 1 , Figure 3 , Figure 9 , Figure 10 As shown, the present invention also includes that one end of the arc-shaped positioning tube 12 away from the arc-shaped tube 14 is closed, a first spring 15 is connected between the arc-shaped tube 14 and the arc-shaped positioning tube 12, and one end of the arc-shaped positioning tube 12 away from the arc-shaped tube 14 is fixedly connected to a vertically arranged driving rod 16; The arc plate 3 is connected to a horizontally arranged moving rod 17 , and the moving rod 17 away from the arc plate 3 is connected to a toggle rod 19 via a second spring 18 .

[0026] When in use, before the hollow glass brick half-blank welding operation begins, relying on the elastic force of the first spring 15, the arc tube 14 has a certain degree of shielding on the air supply hole 13 on the air outlet pipe, and the air supply is at a relatively low level; with the rotation of the drum 2, the arc plate 3 is driven to make a circular motion around the central axis of the drum 2, and when the arc plate 3 moves, the moving rod 17 also moves synchronously, and drives the toggle rod 19 to move synchronously; When the arc-shaped plate 3 moves to a specific position, the toggle rod 19 starts to contact and press the upper end of the driving rod 16. As the arc-shaped plate 3 continues to move, the pressing force exerted by the toggle rod 19 on the driving rod 16 gradually increases, driving the arc-shaped positioning tube 12 to move along the rotation direction of the rotating cylinder 2, and causing the flame spraying and heating plate 8 to move synchronously. Multiple groups of flame spraying holes 11 on the square groove 10 start to heat the two groups of semi-finished products. The flame spraying holes 11 only heat specific parts of the semi-finished products, avoiding overall heating, thereby reducing the waste of gas; When the arc-shaped positioning tube 12 moves, the arc-shaped tube 14 slides inside the arc-shaped positioning tube 12, and the shielding amount of the arc-shaped tube 14 on the air supply hole 13 gradually decreases. As the shielding amount decreases, the amount of gas entering the flame spraying and heating plate 8 through the air supply hole 13 increases, thereby increasing the gas supply volume and further improving the heating effect on the semi-finished products. The flame spraying and heating plate 8 gradually increases the firepower during the movement, which can effectively avoid the problem of damage caused by the rapid temperature rise of the semi-finished hollow glass bricks, and ensure the heating efficiency of the semi-finished hollow glass bricks; When the arc-shaped positioning tube 12 moves to a certain position, the heating of the semi-finished hollow glass bricks is completed. At the same time, the arc-shaped positioning tube 12 moves to the limit, and the toggle rod 19 cannot continue to drive the driving rod 16 to move. At this time, when the second spring 18 is squeezed and cannot push the driving rod 16 to move further, the second spring 18 undergoes elastic deformation, causing the toggle rod 19 to gradually cross over the driving rod 16; After the toggle rod 19 crosses over the driving rod 16, the first spring 15 drives the arc-shaped positioning tube 12 to reset. During the reset process of the arc-shaped positioning tube 12, the arc-shaped tube 14 also slides inside the arc-shaped positioning tube 12, and the shielding amount of the arc-shaped tube 14 on the air supply hole 13 gradually increases, thereby reducing the gas supply volume, facilitating the automatic adjustment of the gas supply volume according to the processing situation, effectively reducing resource waste, and preparing for the heating of the next semi-finished product; It should be noted that during the actual working process of the present invention, the arc-shaped tube 14 always remains in a fixed state and does not move, avoiding the synchronous movement of the arc-shaped tube 14 when the arc-shaped positioning tube 12 moves. Once the arc-shaped tube 14 moves, it will cause the gas supply of the flame spraying and heating plate 8 to be unstable, thereby seriously affecting the heating effect on the semi-finished products.

[0027] To facilitate adjusting the positions of the upper clamping die 4 and the lower clamping die 5 according to the thickness of the semi-finished product, exemplarily, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, the present invention further includes that a plurality of groups of circumferentially distributed positioning rods 20 are fixedly connected to the lower surface of the special-shaped track 7, and the lower ends of the positioning rods 20 pass through the support table 1 and are slidably connected to the support table 1; A moving ring 21 is provided on the lower surface of the special-shaped track 7, and vertically penetrating threaded holes are provided on the arc plate 3 and the moving ring 21. The thread groove of the moving ring 21 and the thread groove of the arc plate 3 have opposite rotation directions. The threaded rod 22 is connected to the thread in the thread groove, and the upper end of the threaded rod 22 is fixedly connected to the first gear 23. A roller 24 that is in rolling contact with the lower surface of the special-shaped track 7 is installed on the upper surface of the moving ring 21. A plurality of groups of vertically arranged moving grooves 25 are provided on the outer side of the rotating drum 2, and a moving block 26 that is slidably connected to the moving groove 25 is provided on the inner side of the arc plate 3.

[0028] When in use, the first gear 23 is driven to rotate, and the first gear 23 drives the threaded rod 22 to start rotating, driving the moving ring 21 and the arc plate 3 to move in opposite directions; As the threaded rod 22 continues to rotate, the moving ring 21 moves along the axial direction of the threaded rod 22. The moving ring 21 gradually squeezes the special-shaped track 7 during the movement, pushing the special-shaped track 7 to move upward. The positioning rod 20 ensures that the special-shaped track 7 remains stable during the rising process. The upward movement of the special-shaped track 7 will drive the support roller 6 installed above to rise synchronously, and the lower clamping die 5 will also rise together with the support roller 6, thereby realizing the adjustment of the position of the lower clamping die 5. At the same time, the arc plate 3 moves downward along the axial direction of the threaded rod 22, and the moving block 26 on the inner side of the arc plate 3 slides in the moving groove 25, limiting the arc plate 3 to move only in the vertical direction, thereby ensuring the stability of the movement of the arc plate 3 and enhancing the stability of the connection between the arc plate 3 and the rotating drum 2; the downward movement of the arc plate 3 will drive the upper clamping die 4 to descend synchronously, thereby realizing the adjustment of the position of the upper clamping die 4; According to the change in the distance between the upper clamping die 4 and the lower clamping die 5, until the moving ring 21 and the arc plate 3 move to a suitable position, at this time, the distance between the upper clamping die 4 and the lower clamping die 5 has been adjusted according to the thickness of the half-blank; if the half-blank is thicker, the lower clamping die 5 is lowered and the upper clamping die 4 is raised by rotating the threaded rod 22, thereby increasing the distance between the upper clamping die 4 and the lower clamping die 5; if the half-blank is thinner, the lower clamping die 5 is raised and the upper clamping die 4 is lowered, thereby reducing the distance between the upper clamping die 4 and the lower clamping die 5; During the processing of hollow glass brick welding half-blanks, the driving rod 16 moves synchronously when the rotating drum 2 drives the curved plate 3 to move, thereby driving the moving ring 21 to rotate. When the moving ring 21 rotates, it is squeezed and contacted with the lower surface of the special-shaped track 7 through the roller 24, providing support for the special-shaped track 7. At the same time, the rolling contact of the roller 24 can reduce the wear between the moving ring 21 and the special-shaped track 7.

[0029] In order to facilitate driving the first gear 23 to rotate, for example, Figure 1 , Figure 2As shown in the figure, the present invention further includes that a first driving motor 27 is provided on the upper surface of the rotating cylinder 2. The output shaft of the first driving motor 27 is fixedly connected with a second gear 28. A toothed ring 29 is rotatably connected to the upper surface of the rotating cylinder 2. Tooth structures are provided on both the inner and outer sides of the toothed ring 29. The second gear 28 is in meshing transmission with the inner side of the toothed ring 29, and the first gear 23 is in meshing transmission with the outer side of the toothed ring 29.

[0030] During use, when the first driving motor 27 is turned on, the output shaft of the first driving motor 27 drives the second gear 28 to rotate. When the second gear 28 rotates, through the meshing transmission between gears, it will drive the toothed ring 29 to rotate on the upper surface of the rotating cylinder 2. As the toothed ring 29 rotates, the tooth structure on the outer side will interact with the first gear 23, thereby driving the first gear 23 to rotate. After the first gear 23 rotates, it will drive the threaded rod 22 to rotate, and further drive the moving ring 21 and the arc plate 3 to move up and down, realizing the adjustment of the positions of the equipment components according to the thickness of the semi-finished blank.

[0031] Exemplarily, as Figure 1 , Figure 4 shown in the figure, the present invention further includes that a sliding block 30 is connected to the back of the lower clamping die 5, and a slide rail 31 that is slidably connected to the sliding block 30 is installed at the lower part of the arc plate 3.

[0032] During use, as the rotating cylinder 2 continues to rotate, the rotating cylinder 2 rotates around the central axis of the support table 1. The driving force generated by the rotation of the rotating cylinder 2 will be transmitted to the arc plate 3, driving the arc plate 3 to perform a circular motion around the central axis of the rotating cylinder 2. During the movement of the arc plate 3, the slide rail 31 installed at the lower part will move accordingly. When the slide rail 31 moves, it relies on the sliding block 30 to synchronously move the lower clamping die 5. At the same time, the support roller 6 rolls on the special-shaped track 7; When the support roller 6 gradually moves to the position where the ramp 9 is provided on the special-shaped track 7, it will be subjected to the upward acting force of the ramp 9, causing the lower clamping die 5 to move upward. The lower clamping die 5 will drive the sliding block 30 to start sliding upward on the slide rail 31. The sliding connection between the sliding block 30 and the slide rail 31 ensures that the moving direction of the lower clamping die 5 can only be along the vertical direction of the slide rail 31, ensuring the stability and accuracy of the movement of the lower clamping die 5; When the threaded rod 22 drives the moving ring 21 to move, the moving ring 21 will gradually squeeze the special-shaped track 7 and drive the special-shaped track 7 to move. When the special-shaped track 7 moves upward or downward, it drives the support roller 6 and the lower clamping die 5 to rise or fall synchronously. During the process of the lower clamping die 5 moving with the special-shaped track 7 and the support roller 6, the sliding block 30 will slide on the slide rail 31, ensuring the smoothness and stability of the movement of the lower clamping die 5.

[0033] Exemplarily, as Figure 1 , Figure 2 , Figure 3As shown, the present invention also includes that the upper outer portion of the arc plate 3 is connected to the upper end of the electric telescopic rod 32, the lower end of the electric telescopic rod 32 is fixedly connected to the extrusion plate 33, both sides of the upper clamping die 4 are hinged to the upper end of the clamping plate 34 through a spring axis, and the upper end of the clamping plate 34 is connected to a swing arm 35 that is in extrusion contact with the lower surface of the extrusion plate 33.

[0034] When in use, first, place the semi-blank to be processed under the upper clamping die 4. At this time, drive the electric telescopic rod 32 to drive the extrusion plate 33 to rise. Under the elastic force of the spring shaft, the swing arm 35 drives the clamping plate 34 to swing inward, so that the clamping plate 34 clamps and fixes the semi-blank under the upper clamping die 4, ensuring that the semi-blank remains stable during the processing; After the clamping of the half blank under the upper clamping die 4 is completed, the other half blank to be welded is placed on the upper surface of the lower clamping die 5, and the position is adjusted so that the welding positions of the two groups of half blanks correspond to each other, laying the foundation for the subsequent welding operation; When the two groups of half-blanks are welded and the upper clamping die 4 and the lower clamping die 5 are separated, the electric telescopic rod 32 is driven again to move the extrusion plate 33 downward and squeeze the swing arm 35, and the swing arm 35 drives the clamping plate 34 to expand outward, so that the clamping plate 34 releases the clamping of the half-blanks after welding; when the electric telescopic rod 32 opens the clamping plate 34, the rotation of the drum 2 can be stopped, so that the operator can take out the processed half-blanks, and then the two new groups of half-blanks are placed under the upper clamping die 4 and above the lower clamping die 5 respectively, ready for the next round of welding processing; It should be noted that when the drum 2 stops rotating, the toggle rod 19 is about to be separated from the driving rod 16. At this time, the toggle rod 19 adjusts the firepower of the flame-spraying heating plate 8 to the maximum state, thereby quickly heating the hollow glass brick half-blank.

[0035] For example, Figure 1 , Figure 5 As shown, the present invention also includes that a plurality of groups of circumferentially distributed support legs 38 are fixedly connected to the lower surface of the support platform 1, a support rod 36 is fixedly connected to the support leg 38, a second drive motor 37 is fixedly connected to the upper surface of the support rod 36, and the output shaft of the second drive motor 37 is fixedly connected to the lower surface of the rotating drum 2.

[0036] During use, when the drum 2 needs to start rotating, the second drive motor 37 drives the drum 2 to start rotating around its central axis; the support rod 36 can ensure the stability of the second drive motor 37 and ensure the normal rotation of the drum 2.

[0037] When the present invention is in use, the spacing between the upper clamping die 4 and the lower clamping die 5 can be adjusted according to the thickness of the half-blank. By driving the first gear 23 to rotate, the threaded connection between the threaded rod 22 and the arc-shaped plate 3 and the moving ring 21 and the opposite thread rotation direction are utilized to realize the reverse movement of the moving ring 21 and the arc-shaped plate 3, thereby driving the special-shaped track 7, the supporting roller 6, the lower clamping die 5 and the upper clamping die 4 to move up and down, so as to match the processing requirements of the half-blanks with different thicknesses. The half-blanks of hollow glass bricks are placed under the upper clamping mold 4 and on the upper surface of the lower clamping mold 5 respectively. The half-blanks placed under the upper clamping mold 4 need to drive the electric telescopic rod 32 to drive the extrusion plate 33 to rise, and use the elastic force of the spring shaft to drive the swing arm 35 to drive the clamping plate 34 to swing inward, so as to fix the half-blanks; the half-blanks on the lower clamping mold 5 need to be adjusted to ensure that the welding positions of the two groups of half-blanks correspond, and at the same time, the gas source is connected to the arc tube 14; The second driving motor 37 is turned on to drive the drum 2 to rotate around its central axis. The rotation of the drum 2 drives the arc plate 3, the upper clamping die 4, and the lower clamping die 5 to make a circular motion around the central axis of the drum 2. As the drum 2 rotates, when the semi-blank moves into the action range of the flame-spraying heating plate 8, the gas enters the hollow structure of the flame-spraying heating plate 8 from the arc tube 14 through the gas supply hole 13 on the inner wall of the arc-shaped positioning tube 12, and then sprays out from the flame-spraying holes 11 on the upper and lower edges of the square groove 10 and is ignited. The flame heats the side of the semi-blank clamped by the upper clamping die 4 and the lower clamping die 5 that is close to each other. During the heating process, as the arc plate 3 moves, the extrusion force applied by the toggle rod 19 to the driving rod 16 gradually increases, driving the arc positioning tube 12 to move along the rotation direction of the drum 2, and making the flame-spraying heating plate 8 move synchronously, and the multiple groups of flame-spraying holes 11 on the square groove 10 begin to heat the two groups of half-blanks. The flame-spraying holes 11 only heat specific parts of the half-blanks, avoiding overall heating, thereby reducing the waste of gas; The arc tube 14 slides in the arc positioning tube 12, and the blocking amount of the arc tube 14 on the air supply hole 13 gradually decreases. As the blocking amount decreases, the amount of gas entering the flame-spraying heating plate 8 through the air supply hole 13 increases, thereby increasing the gas supply and further improving the heating effect on the half-blank. The flame-spraying heating plate 8 gradually increases the firepower during the movement, which can effectively avoid the problem of damage to the hollow glass brick half-blank due to rapid heating, and ensure the heating efficiency of the hollow glass brick half-blank; when the arc positioning tube 12 moves to a certain position, the heating of the hollow glass brick half-blank is completed, and at the same time, the arc positioning tube 12 moves to the limit, and the toggle rod 19 can no longer drive the drive rod 16 to move. At this time, when the second spring 18 is squeezed and cannot push the drive rod 16 to move further, the second spring 18 undergoes elastic deformation, causing the toggle rod 19 to gradually pass over the drive rod 16; After the toggle lever 19 passes over the drive lever 16, the first spring 15 drives the arc-shaped positioning tube 12 to reset. During the reset process of the arc-shaped positioning tube 12, the arc-shaped tube 14 also slides within the arc-shaped positioning tube 12, and the amount of occlusion of the air supply hole 13 by the arc-shaped tube 14 gradually increases, thereby reducing the air supply volume, facilitating the automatic adjustment of the gas supply volume according to the processing conditions, effectively reducing resource waste, and preparing for the heating of the next semi-finished blank; The rotating cylinder 2 continues to rotate, and the support roller 6 rolls along the special-shaped track 7. When the support roller 6 moves to the position where the special-shaped track 7 is provided with a ramp 9, it moves upward under the action of the ramp 9, driving the lower clamping die 5 to slide upward. When the lower clamping die 5 rises to a predetermined position, the semi-finished blank on it is butted against and squeezed into contact with the semi-finished blank on the upper clamping die 4, and they are quickly welded into one body to form a hollow glass brick; After the welding is completed, the lower clamping die 5 continues to move and descend under the guidance of the special-shaped track 7, and the upper clamping die 4 drives the welded glass brick to move along a predetermined path. When the glass brick moves to a specified position, the driving electric telescopic rod 32 is driven to move the pressing plate 33 downward, and the pressing swing arm 35 drives the clamping plate 34 to expand outward, releasing the clamping of the semi-finished blank after welding. When the electric telescopic rod 32 opens the clamping plate 34, the rotation of the rotating cylinder 2 can be paused to facilitate the operator to take out the processed semi-finished blank. Subsequently, two new semi-finished blanks are respectively placed below the upper clamping die 4 and above the lower clamping die 5 again, preparing for the next round of welding processing; When the rotating cylinder 2 stops rotating, the toggle lever 19 is about to disengage from the drive lever 16. At this time, the toggle lever 19 adjusts the firepower of the flame spraying heating plate 8 to the maximum state. At this time, the toggle lever 19 adjusts the firepower of the flame spraying heating plate 8 to the maximum state, so as to quickly heat the semi-finished blank of the hollow glass brick.
