[0056] Description of Reference Numerals

[0057] DETAILED DESCRIPTION

[0058] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0059] Figure 1 This is a structural diagram of a sealing strip welding machine according to one embodiment of the present invention. Figure 7 1 is a structural diagram of a sealing strip welding machine according to an embodiment of the present invention. Figure 1 and Figure 7 In the embodiment, the sealing strip welding machine may include two welding modules, a magnetic adjustment component and a hot melt component. Specifically, the welding module may include a plurality of sealing strip mold notches 6.

[0060] The two welding modules are arranged in parallel, each with two diagonally spaced sealing strip mold slots 6 formed inside. A magnetic adjustment assembly is positioned near the rear of the center region between the two welding modules and is used to move between the two welding modules to adjust the position of the magnetic strips within the sealing strip mold slots 6. A hot melt assembly is positioned outside the center region between the two welding modules and is used to move between the two welding modules to hot melt the opposing ends of the two sealing strips.

[0061] When welding multiple sealing strips, the magnetic adjustment assembly is moved between the two welding modules, and the two sealing strips are then inserted along the notches 6 of the two sealing strip molds. As the sealing strips are inserted along the notches 6 of the sealing strip molds and fit into the magnetic adjustment assembly, the magnetic adjustment assembly adjusts the position of the magnetic strips within the sealing strips. After the magnetic adjustment assembly completes the adjustment, the hot melt assembly enters the middle of the two welding seats 9 and hot melts the opposing ends of the two sealing strips. The hot melt assembly then exits the middle of the two welding modules, driving the two welding modules to close the molds. The two opposing sealing strips are hot melted together, completing the welding of the two sealing strips.

[0062] Traditional sealing strip welding machines generally rely on skilled operators to adjust the position of the magnetic strips inside two relative sealing strips, and sometimes even require operators to reach into the interior of the two welding modules for adjustment. On the one hand, this reduces the efficiency and pass rate of sealing strip welding, and greatly increases production costs for factories with frequent personnel changes. On the other hand, there are certain safety hazards. In this embodiment of the present invention, the use of a magnetic adjustment component and two welding modules to adjust the position of the magnetic strips inside the sealing strip can reduce the dependence of the magnetic strip position adjustment on personnel experience. At the same time, when the operator inserts the sealing head, the position of the magnetic strip is accurately adjusted, which greatly improves the efficiency and pass rate of sealing strip welding, and also reduces the production costs caused by the lack of skill of new operators. In addition, the magnetic adjustment component automatically adjusts the position of the magnetic strip, and does not require the operator to reach into the interior of the welding machine, thereby eliminating safety risks during the sealing strip welding process.

[0063] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the welding module may include a welding seat 9 and a pressing assembly 5. Specifically, the welding seat 9 may include a first connecting block 7, a second connecting block 30 and a third connecting block 8.

[0064] The sealing strip mold notch 6 is defined on the welding base 9. The second connecting block 30 is positioned on the side of the first connecting block 7, and the third connecting block 8 is positioned on the side of the second connecting block 30 away from the first connecting block 7. The second and third connecting blocks 30, 8, and the first connecting block 7 cooperate to form the sealing strip mold notch 6. A pressing assembly 5 is positioned on the side of the welding base 9 to press and secure the two sets of sealing strips outside the sealing strip mold notches 6.

[0065] After the magnetic adjustment assembly adjusts the position of the magnetic strip, the press assembly 5 presses the sealing strip and then withdraws from between the two welding seats 9. The press assembly 5 can stably press and fix the sealing strip during the welding process. After welding is completed, the second connecting block 30 and the third connecting block 8 are separated from the first connecting block 7, and the sealing strip mold notch 6 is opened, making it easier for the operator to remove the welded sealing strip.

[0066] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the sealing strip mold notches 6 on each group of welding modules are provided with multiple layers. Specifically, the multiple layers of sealing strip molds are distributed in a stepped manner from bottom to top.

[0067] When multiple sealing strips need to be welded, the magnetic adjustment component needs to be moved to the middle of the two sets of welding modules, and then the multi-layer sealing strips need to be inserted from bottom to top along the multi-layer sealing strip mold slot 6. Since the multi-layer sealing strip mold slot 6 is distributed in a stepped shape, insertion from bottom to top does not affect the operator's search for the port of the sealing strip mold slot 6.

[0068] In this embodiment of the present invention, considering the convenience and safety of the operator's operation, the intersection of the two groups of diagonal sealing strip mold notches 6 is located at the end away from the operator.

[0069] In this embodiment of the invention, Figure 4 、 Figure 5 As shown in the figure, the magnetic adjustment assembly can include a magnetic adjustment box 11, two magnetic adjustment fixing blocks 21 and a drive assembly. Specifically, the magnetic adjustment box 11 can include multiple magnetic adjustment openings 27; the magnetic adjustment fixing block 21 can include multiple support blocks 22 and multiple magnetic adjustment pins 23.

[0070] The magnetic adjustment box 11 is provided with multiple magnetic adjustment openings 27 on both sides perpendicular to its direction of movement, which mate with the multiple sealing strip mold notches 6. Two magnetic adjustment fixed blocks 21 are rotatably mounted within the magnetic adjustment box 11. Multiple support blocks 22 protrude from the sidewalls of the magnetic adjustment fixed blocks 21, arranged vertically. Magnetic adjustment pins 23 are positioned on the side of the support blocks 22 closest to the corresponding magnetic adjustment openings 27. A drive assembly is positioned between the two magnetic adjustment fixed blocks 21, driving the two magnetic adjustment fixed blocks 21 away from each other and driving the magnetic adjustment pins 23 through the corresponding magnetic adjustment openings 27 to push the magnetic strip within the sealing strip.

[0071] When the position of the magnetic strip inside the sealing strip needs to be adjusted, the drive assembly starts and pushes the two magnetic adjustment fixed blocks 21 to rotate and move away from each other, so that the multiple support blocks 22 distributed vertically drive the corresponding magnetic adjustment needles 23 through the corresponding magnetic adjustment openings 27 and enter along the end of the sealing strip, pushing the magnetic strip to move, thereby adjusting the position of the magnetic strip inside the sealing strip. The multiple support blocks 22 distributed vertically synchronously drive the corresponding magnetic adjustment needles 23 to move, which can achieve synchronous adjustment of the position of the magnetic strips of multiple layers of sealing strips. Using the drive assembly to drive the two magnetic adjustment fixed blocks 21 away from each other can achieve synchronous adjustment of the position of the magnetic strips inside two relative sealing strips, further improving the adjustment efficiency of the magnetic strips inside the sealing strip.

[0072] In this embodiment of the invention, Figure 4 and Figure 5 As shown, the driving assembly may include an inverted U-shaped clamping plate, a round table 25 and a driving cylinder 20.

[0073] An inverted U-shaped clamping plate 24 is mounted on two opposing support blocks 22, with its ends positioned above the corresponding support blocks 22. A truncated platform 25 is mounted below the two opposing support blocks 22 and connected to the inverted U-shaped clamping plate 24. The bottom of each support block 22 features a first inclined surface that mates with the sidewall of the truncated platform 25, while the top of each support block 22 features a second inclined surface 26 that mates with the inverted U-shaped clamping plate 24. A drive cylinder 20 is mounted at the bottom of the magnetic adjustment box 11, with its output end connected to the bottom of the truncated platform 25.

[0074] When the position of the magnetic strip inside the sealing strip needs to be adjusted, the driving cylinder 20 is activated and pushes the circular table 25 and the inverted U-shaped clamp 24 upward. The circular table 25 pushes the support blocks 22 in contact with it away from each other through the first inclined surface and drives the remaining support blocks 22 to rotate and move away from each other. The inverted U-shaped clamp 24 cooperates with the support blocks 22 in contact with it to define the position of the two magnetic adjustment fixing blocks 21, and at the same time cooperates with the circular table 25 to clamp and fix the two magnetic adjustment fixing blocks 21. The method of using the circular table 25 to cooperate with the support blocks 22 can achieve stable pushing and mutual separation of the relative support blocks 22, and the method of using the inverted U-shaped clamp 24 to cooperate with the support blocks 22 can achieve stable limitation and clamping of the support blocks 22.

[0075] In this embodiment of the present invention, the driving device for driving the magnetic adjustment box 11 to enter or move out between the two welding seats 9 can be in various forms known to those skilled in the art, such as a cylinder, a motor that rotates to drive the screw to rotate and thereby drive the magnetic adjustment box 11 to move. However, in a preferred embodiment of the present invention, considering the stability and accuracy of the movement of the magnetic adjustment box 11, the driving device of the magnetic adjustment box 11 can be as follows: Figure 7 and Figure 8 Specifically, Figure 7 and Figure 8 In the embodiment, the driving device may include a bracket 41, a movable cylinder 42 and a second slide rail. Specifically, the second slide rail is arranged at the bottom of the bracket 41, the movable cylinder 42 is slidably connected to the second slide rail, and the output end of the movable cylinder 42 is connected to the magnetic adjustment box 11.

[0076] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the welding module may further include a pushing cylinder 10 , a pushing plate 29 and a pushing column 28 .

[0077] The pushing cylinder 10 is arranged on the side of the third connecting block 8 away from the second connecting block 30; the pushing plate 29 is arranged on the side of the pushing cylinder 10 away from the third connecting block 8, and the output end of the pushing cylinder 10 is connected to the pushing plate 29; one end of the pushing column 28 is connected to the pushing plate 29, and the other end of the pushing column 28 movably passes through the third connecting block 8 and is fixedly connected to the second connecting block 30.

[0078] After the first connecting block 7 and the third connecting block 8 are separated, the pushing cylinder 10 is started and moves through the pushing plate 29 and the pushing column 28 to drive the second connecting block 30 away from the third connecting block 8, thereby causing the welded sealing strip to be dislocated and partially moved out of the sealing strip mold groove 6, further improving the convenience and efficiency of the operator in taking the welded sealing strip.

[0079] In this embodiment of the invention, Figure 7 、 Figure 8 and Figure 9 As shown, the welding machine may further include a workbench 1 , a first support plate 32 , two groups of first support seats 33 , a first slide rail, a mold-parting cylinder 34 and two groups of second support seats 35 .

[0080] A first support plate 32 is disposed below the two sets of first connecting blocks 7. Two sets of first support seats 33 are disposed on top of the first support plate 32. The two sets of first support seats 33 are respectively connected to the bottom of the corresponding first connecting blocks 7. A first slide rail is disposed on top of the workbench 31. The first support plate 32 is slidably connected to the first slide rail. A mold-parting cylinder 34 is disposed on top of the workbench 31. The output end of the mold-parting cylinder 34 is connected to the first support plate 32 and is used to drive the two sets of first connecting blocks 7 to move along the first slide rail to open the sealing strip mold notch 6. Two sets of second support seats 35 are disposed on top of the workbench 31. Two sets of third connecting blocks 8 are respectively disposed on top of the two sets of second support seats 35.

[0081] After the sealing strip is welded, the mold-parting cylinder 34 starts and drives the first support plate 32 to move along the first slide rail, while driving the two groups of first support seats 33 and the corresponding first connecting blocks 7 to move away from the corresponding third connecting blocks 8. The sealing strip mold slot 6 is opened, and the operator can remove the welded sealing strip, which is simple and convenient.

[0082] In this embodiment of the invention, Figure 7 、 Figure 8 and Figure 9 As shown, the welding machine may further include a first connecting seat 36, a second connecting seat 37, a movable shaft 38, a second supporting plate 39 and a mold clamping cylinder.

[0083] A first connecting seat 36 is mounted on the side wall of the second support seat 35, and a second connecting seat 37 is mounted on the side wall of the first support seat 33. A movable shaft 38 flexibly extends through the first connecting seat 36, with one end of the movable shaft 38 fixedly connected to the second connecting seat 37. A second support plate 39 is mounted on top of the adjacent first and second support seats 33 and 35, with one side of the second support plate 39 abutting against the side wall of one set of welding seats 9, facing away from the other set of welding seats 9. A mold clamping cylinder is mounted on top of the workbench 31, with its output end connected to the other side of the second support plate.

[0084] When the mold-parting cylinder 34 opens the mold, the first support seat 33 moves along the movable shaft 38 via the second connecting seat 37, causing one end of the movable shaft 38 to slide along the first connecting seat 36. When the sealing strip needs to be welded together, the mold-closing cylinder is activated and, via the second support plate 39, drives the corresponding first and second support seats 33, 35 until the mold is closed, thus achieving stable mold closing of the welding machine. The second support plate 39 engages the sidewalls of the first and second support seats 33, 35 to prevent damage to the movable shaft 38.

[0085] In this embodiment of the invention, Figure 7 and Figure 9 As shown, the welding machine may further include two sets of abutment plates 40. Specifically, the two sets of abutment plates 40 are respectively arranged on another set of first support seats 33 and second support seats 35, which can abut and buffer the corresponding first connecting block 7 and third connecting block 8, thereby preventing the pins connecting the first connecting block 7 and third connecting block 8 with the corresponding first support seats 33 and second support seats 35 from breaking, thereby increasing the service life of the welding machine. In this embodiment of the present invention, as Figure 1 and Figure 3 As mentioned above, the welding module may further include a plurality of auxiliary base plates 1 and a plurality of baffles 2 .

[0086] One end of each of the auxiliary bottom plates 1 is connected to the end of the corresponding sealing strip mold notch 6 , and each of the baffles 2 is disposed on the top of the corresponding auxiliary bottom plates 1 .

[0087] After the operator inserts the sealing strip along the sealing strip mold notch 6, the pressing assembly 5 presses along the other end of the auxiliary base plate 1 to secure the sealing strip. The auxiliary base plate 1 and the baffle 2 are arranged in cooperation at the end of the sealing strip mold notch 6 to assist the operator in inserting the sealing strip, further improving the operator's operating efficiency. In addition, the pressing assembly 5 presses against the other end of the auxiliary base plate 1, extending the length of the sealing strip outside the sealing strip mold notch 6. At the same time, the auxiliary base plate 1 and the baffle 2 cooperate to limit the two sides of the sealing strip, which helps to reduce the deformation amplitude of the sealing strip inside the sealing strip mold notch 6, thereby improving the stability and reliability of the sealing strip during magnetic adjustment and welding.

[0088] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the pressing assembly 5 may include a plurality of pressing plates 3 , a pressing cylinder 4 and a top plate 12 .

[0089] Multiple pressing plates 3 are distributed in a stepped manner and are respectively located at the top of the other end of the corresponding auxiliary base plate 1. The pressing cylinder 4 is arranged on the side wall of the welding seat 9. A top plate 12 is provided at the output end of the pressing cylinder 4, and the top plate 12 is connected to the ends of the multiple pressing plates 3.

[0090] When multiple layers of sealing strips need to be pressed, the pressing cylinder 4 is activated and drives the multiple pressing plates 3 to descend synchronously through the top plate 12 to achieve synchronous pressing of the multiple layers of sealing strips. Conversely, driving the multiple pressing plates 3 to rise synchronously makes it easier for operators to insert or remove sealing strips.

[0091] In this embodiment of the present invention, the hot melt assembly may include a heating device and a steering assembly.

[0092] The heating device is arranged below the middle of the two welding seats 9, and the steering assembly is arranged on the workbench and connected to the heating device for driving the heating device to rotate to the middle of the two welding seats 9 to heat-melt the two sealing strips.

[0093] When the sealing strips need to be heat-melted, the steering assembly starts and drives the heating device into the middle of the two sealing strips, and heat-melts the opposite sides of the two sealing strips so that the two sealing strips can be bonded during subsequent mold closing. The use of the heating device heat-melt welding method is convenient and efficient.

[0094] In this embodiment of the present invention, the specific structure of the heating device includes but is not limited to a heating plate and the like.

[0095] In this embodiment of the present invention, the specific structure of the steering assembly includes but is not limited to a method in which the cylinder directly rotates the shaft to drive the heating device to rotate, a method in which the motor drives the heating device to rotate, etc.

[0096] In this embodiment of the invention, Figure 2 and Figure 4 As shown, the sealing strip welding machine may further include two fixed plates 14 , a rotating shaft 16 , a scraper 19 , a steering plate 15 and a steering cylinder 13 .

[0097] Two fixed plates 14 are arranged parallel to the side walls of the magnetic adjustment box 11 facing the two welding seats 9. A rotating shaft 16 is arranged between the two fixed plates 14. One end of the rotating shaft 16 is hinged to one of the fixed plates 14, and the other end of the rotating shaft 16 moves through the other fixed plate 14 and is fixedly connected to the steering plate 15. A scraper 19 is fixedly arranged on the outside of the rotating shaft 16. The steering cylinder 13 is arranged on the magnetic adjustment box 11, and the output end of the steering cylinder 13 is rotatably connected to the end of the steering plate 15.

[0098] When the sealing strip needs to be magnetically adjusted, the scraper 19 is in a state of intersecting with the line connecting the two welding seats 9. Therefore, when the magnetic adjustment box 11 moves between the two welding seats 9, the scraper 19 will not affect the magnetic adjustment effect of the two sealing strips. After the sealing strip is welded, a lot of sealing strip waste will remain on the inner walls of the two welding seats 9. The steering cylinder 13 is then driven to move to drive the steering plate 15 to rotate. The steering plate 15 drives the scraper 19 to rotate parallel to the line connecting the two welding seats 9 through the rotating shaft 16. The magnetic adjustment box 11 is then driven to move repeatedly along the middle of the two welding seats 9, so that the scraper 19 can scrape off the sealing strip waste on the opposite inner walls of the two welding seats 9 to facilitate the subsequent welding of the sealing strip.

[0099] In this embodiment of the present invention, the sealing strip welding machine further includes a cylinder 17 and a ring 18. Specifically, the cylinder 17 is positioned at the end of the steering plate 15, and the ring 18 is sleeved outside the cylinder 17 and connected to the output end of the steering cylinder 13. Specifically, when cleaning debris from the inner walls of the two welding seats 9, the steering cylinder 13 rotates the scraper 19 through the cooperation of the ring 18 and the cylinder 17.

[0100] In this embodiment of the present invention, the scraper 19 may be made of various materials known to those skilled in the art, such as steel plates, brushes, etc. However, in a preferred embodiment of the present invention, the scraper 19 may be made of hard plastic in consideration of its effectiveness in scraping off sealing strip waste.

[0101] In this embodiment of the present invention, the number of the sealing strip mold notches 6 on each welding seat 9 can be various forms known to those skilled in the art, such as 2, 4, etc. However, in a preferred embodiment of the present invention, considering the shape of the welding seat 9 and the stability of the sealing strip limit, the number of the sealing strip mold notches 6 on each welding seat 9 can be as follows: Figure 1 and Figure 3 Specifically, Figure 1 and Figure 3 In the embodiment, the number of the sealing strip mold notches 6 on each welding seat 9 is three.

[0102] Through the above technical solution, the present invention provides a sealing strip welding machine. By first moving the magnetic adjustment component between the two sets of welding modules and inserting the sealing strip along the inside of the notch 6 of the two sets of sealing strip molds, the magnetic adjustment component synchronously adjusts the magnetic strip positions of the two sets of sealing strips that form a diagonal relationship, and then drives the magnetic adjustment component to reset. The hot melt component enters between the two welding seats to hot melt the two sealing strips, and finally drives the two hot melt sealing strips to fit together to achieve welding of the two sets of sealing strips. The use of the magnetic adjustment component to synchronously adjust the magnetic strip positions of the two sets of sealing strips greatly improves the efficiency and qualified rate of sealing strip welding and reduces production costs. In addition, it also eliminates certain safety hazards.
