Description

Technical Field

[0001] This invention relates to the field of waterproof membrane processing technology, and in particular to an ultrasonic welding device and method for assembling waterproof membranes and suspension hooks. Background Technology

[0002] Waterproofing design is an essential part of underground engineering construction and subsequent use. Therefore, good waterproofing is necessary for environmental protection, water resource protection, and to avoid geological disasters.

[0003] Polyethylene materials have good chemical stability, are suitable for melt molding, have low processing temperature, and good fluidity. In addition, they have good impact resistance and puncture resistance. Therefore, they are particularly suitable as waterproof membranes for use in waterproof design of underground engineering projects.

[0004] When installing waterproof membranes, they need to be laid on the inner wall of underground tunnels. Existing technologies typically use a suspension method for installation, thus requiring the use of suspended waterproof membranes. During the production of suspended waterproof membranes, plastic suspension plates need to be welded onto the membrane to facilitate assembly of the membrane and suspension hooks during construction. While ultrasonic plastic welding machines are commonly used for welding the waterproof membrane and plastic suspension plates, traditional plastic welding processes often involve manual operation of the ultrasonic welding machine after the membrane is extruded. This makes it difficult to simultaneously perform automatic welding of the plastic suspension plates during the membrane extrusion process, resulting in lower production efficiency. Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in traditional welding processes, welding is often carried out manually using an ultrasonic welding machine after the roll material is extruded, which is not convenient for the simultaneous automatic welding of the suspension piece during the roll material extrusion process, and the production efficiency needs to be further improved. The invention proposes an ultrasonic welding device for assembling waterproof roll material and suspension hook.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic welding device for assembling waterproof membrane and suspension hooks, comprising an installation frame and a conveying assembly, wherein the conveying assembly is installed on the installation frame, the waterproof membrane is wound around the conveying assembly, and first limiting grooves are symmetrically provided on both sides of the installation frame, with sliders symmetrically slidably connected within the first limiting grooves, and support rods fixedly connected to the sliders, further comprising: a top plate fixedly connected to the upper end of the support rods; reciprocating telescopic cylinders symmetrically fixedly connected to both sides of the top plate; a lifting plate disposed above the conveying assembly and fixedly connected to the telescopic end of the reciprocating telescopic cylinders; an ultrasonic welding machine fixedly connected at equal intervals to the lower side of the lifting plate; and a pressure block fixedly connected to the ultrasonic welding machine. The welding head of the receiving machine includes a cavity inside the pressure block, a groove on the lower side of the pressure block near the cavity, and the cavity and groove connected by an air hole. Multiple cavities on the pressure blocks are connected by connecting air pipes. A negative pressure assembly for adsorbing the suspension plates into the grooves of the pressure blocks is mounted on the top plate. A support plate is fixedly connected to the front side of the mounting frame. Suspension plate storage cylinders are fixedly connected to the support plate at equal intervals, with each storage cylinder positioned on the same horizontal line as each pressure block. A feeding assembly for ejecting the suspension plates from the storage cylinders is mounted on the side of the support plate away from the pressure blocks. A transmission unit for driving the support rod to reciprocate is mounted on the lower side of the mounting frame.

[0007] To facilitate stable conveying of the roll material, the conveying assembly further includes a first drive roller and a second drive roller. The first drive roller is symmetrically rotatably connected to both sides of the lower end of the mounting frame via a first fixed plate. The second drive roller is symmetrically rotatably connected to both ends of the mounting frame and located between the two first drive rollers. The waterproof roll material is wound around the first drive roller and the second drive roller.

[0008] To facilitate support of the roll material, a plurality of third drive rollers are rotatably connected to the mounting frame between the two second drive rollers. Belts are fitted onto the plurality of third drive rollers and are in contact with the waterproof roll material. A support block is fixedly connected to the mounting frame between every two third drive rollers, and the upper surface of the support block is in slidable contact with the belt.

[0009] To facilitate the adsorption of the roll material, the negative pressure assembly further includes a first air cylinder, a first piston rod with a piston, and a first air pipe. The first air cylinder is symmetrically fixedly connected to both sides of the top plate, and the first piston rod is slidably connected inside the first air cylinder. The lower end of the first piston rod is fixedly connected to the lifting plate. One of the pressure blocks has symmetrically opened air extraction holes on both sides of its cavity. The two air extraction holes are respectively connected to the air inlets of the adjacent first air cylinders through the first air pipe. The upper and lower ends of the first air cylinder away from the air inlet are respectively provided with a first exhaust port and a second exhaust port. A one-way valve is installed in the first exhaust port.

[0010] To facilitate the ejection of the suspension plate from the suspension plate storage cylinder, the feeding assembly further includes a second air cylinder, a second piston rod with a piston, a third air cylinder, a third piston rod with a piston, a push plate, and an elastic rope. The second air cylinder is symmetrically fixedly connected to both sides of the mounting frame near the support plate. The second piston rod is slidably connected inside the second air cylinder, and the end of the second piston rod near the support rod is fixedly connected to the support rod. A first air box is fixedly connected to the bottom of the support plate away from the support rod. A through opening is laterally provided at the bottom of the suspension plate storage cylinder. The third air cylinder is fixedly connected to the support plate near the support rod. Behind the through-hole, the third piston rod is slidably connected inside the third air cylinder, and the push plate is slidably connected to the support plate. The height of the push plate is the same as the height of the through-hole. The third piston rod and the push plate are fixedly connected. The elastic rope is set inside the third air cylinder, and the two ends of the elastic rope are fixedly connected to the inner wall of the third air cylinder and the piston on the third piston rod, respectively. The first air box and the second air cylinder are connected through a second air pipe. The first air box and multiple third air cylinders are connected through third air pipes, respectively. The interiors of the second air cylinder, the first air box, and the third air cylinder are filled with saturated gas.

[0011] To prevent the suspension plate from getting stuck between the third air cylinder and the push plate, a further step is to fix a baffle plate to the upper end of the push plate near the third piston rod.

[0012] To facilitate the stable adsorption of the suspension plate within the groove, a plurality of tension springs are fixedly connected to the side of the support plate near the pressure block. A buffer plate is fixedly connected to the upper end of each tension spring, and the upper surface of the buffer plate is flush with the upper surface of the support plate.

[0013] To facilitate rapid cooling of the roll material, two sets of second air cylinders and second piston rods are symmetrically fixedly connected to the mounting frame. Another set of second air cylinders is symmetrically fixedly connected to both sides of the end of the mounting frame away from the support plate. A second air box is fixedly connected to the inner wall of the mounting frame away from the support plate. The second air box is connected to the two adjacent second air cylinders through a fourth air pipe. One-way valves are installed in the air inlet and outlet of the second air cylinder near the second air box. Multiple air jets are evenly spaced on the side of the second air box near the waterproof roll material.

[0014] This facilitates the synchronous movement of the ultrasonic welding machine and pressure block with the rolled material. Furthermore, the transmission unit includes a sprocket, a half-tooth gear, a rectangular frame, and a rack. The mounting frame is fixedly connected to a second fixed plate between two first fixed plates. A rotating shaft is rotatably connected to both the first and second fixed plates. The rotating shaft on the first fixed plate is fixedly connected to a first transmission roller. The sprocket is fixedly connected to the rotating shaft. The sprocket on the first fixed plate and the sprocket on the second fixed plate are connected by a chain. The half-tooth gear is fixedly connected to the rotating shaft near the second fixed plate. The rectangular frame is fitted onto the half-tooth gear. The upper end of the rectangular frame is fixedly connected to a support rod. The racks are symmetrically installed on the inner side of the rectangular frame, and the two racks intermittently mesh with the half-tooth gear.

[0015] The method for using an ultrasonic welding device for assembling waterproof membrane and suspension hooks includes the following steps:

[0016] S1: Before welding, the workers first place multiple suspension plates into the suspension plate storage cylinder, and then install a set of suspension plates in the groove of the pressure block in advance;

[0017] S2: When the coil material is being moved, the reciprocating telescopic cylinder will drive the ultrasonic welding machine downward through the lifting plate, thereby pressing the suspension plate placed on the pressure block down onto the surface of the coil material.

[0018] S3: When the pressure block presses the suspension plate onto the roll material, the high-frequency vibration generated by the ultrasonic vibrator in the ultrasonic welding machine will be transmitted to the contact surface of the suspension plate and the roll material under a certain pressure, causing high-frequency friction between the two on the contact surface, thereby generating local high temperature. The suspension plate and the roll material at the contact surface melt under the action of high temperature and are held under pressure to solidify, thus achieving welding.

[0019] S4: When the roll material moves, the roll material will drive the transmission part to move through the conveying component, thereby driving the ultrasonic welding machine, pressure block and the roll material to move synchronously, so that the roll material, suspension plate, pressure block and ultrasonic welding machine can be relatively stationary during the welding process, thereby achieving synchronous welding without stopping the machine.

[0020] S5: When the transmission unit drives the pressure block to move back, the suspension plate can be pushed out of the suspension plate storage cylinder by the feeding assembly;

[0021] S6: When the pressure block moves downward to pick up the material, the suspension plate will be adsorbed into the groove by the negative pressure component. Then, the above operation is repeated to continuously weld the suspension plate on the roll.

[0022] Compared with the prior art, the present invention provides an ultrasonic welding device and method for assembling waterproof membrane and suspension hooks, which has the following beneficial effects:

[0023] 1. The ultrasonic welding device for assembling waterproof membrane and suspension hooks, through the coordinated use of the mounting frame, transmission part and conveying components, allows the reciprocating telescopic cylinder, ultrasonic welding machine and pressure block to move synchronously with the membrane when the external winding roller moves the membrane. This ensures that the membrane, suspension plate, pressure block and ultrasonic welding machine can remain relatively stationary during the welding process, thus achieving synchronous welding without stopping the machine. Compared with the existing technology, it can avoid the tedious operation of manual welding after the membrane is extruded. This not only greatly saves labor costs and improves production efficiency, but also improves product quality and enhances brand competitiveness.

[0024] 2. The ultrasonic welding device for assembling waterproof membrane and suspension hooks is also equipped with a suspension plate storage cylinder, support plate, negative pressure component, and feeding component. When a set of suspension plates is welded, the ultrasonic welding machine and pressure block retract, and the suspension plate can be automatically placed on the pressure block without manual operation, which further reduces labor costs and effectively improves welding efficiency.

[0025] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention enables the reciprocating telescopic cylinder, ultrasonic welding machine, and pressure block to move synchronously a distance with the coil material, ensuring that the coil material, suspension plate, pressure block, and ultrasonic welding machine can remain relatively stationary during the welding process. This allows for synchronous welding without stopping the machine. Compared with existing technologies, this invention avoids the tedious manual welding operation after the coil material is extruded. It can not only greatly save labor costs and improve production efficiency, but also improve product quality and enhance brand competitiveness. Attached Figure Description

[0040] Example 1:

[0041] Reference Figures 1-11An ultrasonic welding device for assembling waterproof membrane and suspension hooks includes an installation frame 1 and a conveying assembly.

First limiting grooves 102 are symmetrically provided on both sides of the installation frame 1. A slider 103 is symmetrically slidably connected within the first limiting grooves 102. A support rod 12 is fixedly connected to the slider 103. The device also includes: a top plate 13 fixedly connected to the upper end of the support rod 12; reciprocating telescopic cylinders 14 symmetrically fixedly connected to both sides of the top plate 13; a lifting plate 15 positioned above the conveying assembly and fixedly connected to the telescopic end of the reciprocating telescopic cylinders 14; an ultrasonic welding machine 16 fixedly connected at equal intervals to the lower side of the lifting plate 15; and pressure blocks 17 fixedly connected to the welding head of the ultrasonic welding machine 16.

The lower end of the first piston rod 20 is fixedly connected to the lifting plate 15. The cavity 22 of one of the pressure blocks 17 has symmetrically opened air extraction holes on both sides. The two air extraction holes are respectively connected to the air inlet of the adjacent first air cylinder 19 through the first air pipe 40. The upper and lower ends of the first air cylinder 19 away from the air inlet are respectively opened with a first exhaust port and a second exhaust port. A one-way valve is installed in the first exhaust port.

[0044] The feeding assembly includes a second air cylinder 31, a second piston rod 32 with a piston, a third air cylinder 33, a third piston rod 34 with a piston, a push plate 35, and an elastic rope 36. The second air cylinder 31 is symmetrically fixedly connected to both sides of the mounting frame 1 near the support plate 27. The second piston rod 32 is slidably connected inside the second air cylinder 31. The end of the second piston rod 32 near the support rod 12 is fixedly connected to the support rod 12. A first air box 2701 is fixedly connected to the bottom of the support plate 27 away from the support rod 12. A through opening is laterally opened at the bottom of the suspension plate storage cylinder 28. The third air cylinder 33 is fixedly connected to the rear side of the support plate 27 near the through opening. The third piston rod... 34 is slidably connected inside the third air cylinder 33, and push plate 35 is slidably connected to support plate 27. The height of push plate 35 is the same as the height of the through opening. The third piston rod 34 is fixedly connected to push plate 35. Elastic rope 36 is set inside the third air cylinder 33. The two ends of elastic rope 36 are fixedly connected to the inner wall of the third air cylinder 33 and the piston on the third piston rod 34, respectively. The first air box 2701 is connected to the second air cylinder 31 through the second air pipe 38. The first air box 2701 is connected to multiple third air cylinders 33 through the third air pipes, respectively. The interiors of the second air cylinder 31, the first air box 2701, and the third air cylinder 33 are filled with saturated gas.

[0045] The transmission unit includes a sprocket 8, a half-tooth gear 10, a rectangular frame 11, and a rack 18. The mounting frame 1 is located between two first fixed plates 101 and a second fixed plate is fixedly connected thereto.

The sprocket 8 is fixedly connected to the rotating shaft 7. The sprocket 8 on the first fixed plate 101 and the sprocket 8 on the second fixed plate 101 are connected by a chain 9. The half-tooth gear 10 is fixedly connected to the rotating shaft 7 near the second fixed plate. The rectangular frame 11 is sleeved on the half-tooth gear 10. The upper end of the rectangular frame 11 is fixedly connected to the support rod 12. The racks 18 are symmetrically installed on the inner side of the rectangular frame 11. The two racks 18 intermittently mesh with the half-tooth gear 10.

[0046] When it is necessary to weld suspension plates onto waterproof membranes to facilitate the assembly of the membranes and suspension hooks for rapid waterproofing operations in underground projects, workers can install this device on the waterproof membrane production line. This allows the suspension plates to be automatically installed during the extrusion molding process. After extrusion molding, workers first wind the membrane around the first drive roller 2 and the second drive roller 3, and then fix the ends of the membrane to the external take-up roller. Driving the external take-up roller then allows the membrane to move smoothly and finally be wound up for use during waterproofing operations. Before welding, an encoder is first used to... The length of the roll material passing through the two second drive rollers 3 is calculated, and the ultrasonic welding machine 16 and its accessories are automatically triggered to work after each set interval, thus realizing automatic welding. Before welding, the operator first places multiple suspension plates into the suspension plate storage cylinder 28, and then pre-installs a set of suspension plates in the groove 21 of the pressure block 17. When the roll material is driven, the reciprocating telescopic cylinder 14 will drive the ultrasonic welding machine 16 downward through the lifting plate 15, so that the suspension plates placed on the pressure block 17 are pressed down onto the surface of the roll material. After the pressure block 17 presses the suspension plates tightly onto the roll material, the ultrasonic welding is started. In the ultrasonic welding machine 16, the high-frequency vibration generated by the ultrasonic vibrator is transmitted to the contact surface of the suspension plate and the roll material under a certain pressure, causing high-frequency friction between the two at the contact surface, thereby generating local high temperature. The suspension plate and the roll material at the contact surface melt under the action of high temperature and are then solidified under pressure, thus achieving welding. When the roll material moves, it drives the first transmission roller 2 to rotate. The first transmission roller 2 then drives the sprockets 8 on both sides to rotate through the rotating shaft 7. The sprockets 8 on both sides then drive the sprocket 8 at the middle position to rotate through the chain 9. The sprocket 8 at the middle position then drives the half-tooth gear 10 through the rotating shaft 7. The device rotates, and then the lower rack 18 drives the rectangular frame 11 to move synchronously one distance in the direction of the coil movement. The rectangular frame 11 can then drive the top plate 13 to move via the support rod 12, thereby enabling the ultrasonic welding machine 16, pressure block 17 and the coil to move synchronously. This ensures that the coil, suspension plate, pressure block 17 and ultrasonic welding machine 16 can remain relatively stationary during the welding process, thus achieving synchronous welding without stopping the machine. Compared with the existing technology, this avoids the tedious operation of manual welding after the coil is extruded. It can not only greatly save labor costs and improve production efficiency, but also improve product quality and enhance brand competitiveness.

[0047] When the half-gear 10 separates from the lower rack 18 and meshes with the upper rack 18, it can move the rectangular frame 11 towards the side closer to the support plate 27. Then, the support rod 12 can drive the second piston rod 32 to compress the gas in the second air cylinder 31 into the third air cylinder 33. Since the second air cylinder 31, the first air box 2701, and the third air cylinder 33 are interconnected and filled with gas, when the internal space of the second air cylinder 31 is compressed, the gas will be delivered into the third air cylinder 33. Then, the third piston rod 34 will move against the tension of the elastic rope 36 under the pushing force of the gas. The third piston rod 34 will then push a suspension plate through the push plate 35. When the pressure block 17 moves to its maximum distance, it is positioned directly above the suspended piece. Then, the reciprocating telescopic cylinder 14 moves the pressure block 17 downward, placing the suspended piece in the groove 21 of the pressure block 17. As the reciprocating telescopic cylinder 14 moves the pressure block 17 downward via the lifting plate 15, it also moves the first piston rod 20 downward. Then, the first air pipe 40 can be used to evacuate the cavity 22 inside the pressure block 17. After the suspended piece is placed in the groove 21, it will be adsorbed in the groove 21 under the action of negative pressure, thus enabling automatic material handling of the suspended piece and effectively improving the automation of the device.

[0048] When the half gear 10 meshes with the rack 18 below again, the ultrasonic welding machine 16 and the pressure block 17 can move synchronously with the roll material again. After the pressure block 17 leaves the support plate 27, the pressure block 17 can be controlled to move downward so that the suspension plate is in close contact with the roll material. Then the ultrasonic welding machine 16 can be started again to perform welding work.

[0049] When the pressure block 17 moves to the bottom, the first piston rod 20 also moves to the bottom of the first air cylinder 19. Then, the piston on the first piston rod 20 will be located below the second exhaust port on the first air cylinder 19. Since the cavity 22 of the first air cylinder 19 and the pressure block 17 is under negative pressure, after the second exhaust port is opened, the outside gas will enter the first air cylinder 19 and the cavity 22 through the second exhaust port, thereby eliminating the adsorption force on the suspension plate. When the welding is completed and the pressure block 17 moves upward, it can prevent the pressure block 17 from pulling the suspension plate upward, which would result in the suspension plate and the coil not being welded firmly enough. This effectively ensures the welding quality of the device for welding the coil and the suspension plate. Due to repetition, the suspension plate can be continuously welded on the coil.

[0050] Example 2:

[0051] Reference Figures 1-11The ultrasonic welding device for assembling waterproof membrane and suspension hooks is basically the same as in Example 1, but with a further improvement: multiple third transmission rollers 4 are rotatably connected to the mounting frame 1 between two second transmission rollers 3, and belts 5 are sleeved on the multiple third transmission rollers 4. The belts 5 are in contact with the waterproof membrane. A support block 6 is fixedly connected to the mounting frame 1 between every two third transmission rollers 4. The upper surface of the support block 6 is in contact with the belt 5. Since the waterproof membrane and the belt 5 are in contact, when the waterproof membrane moves, it can drive the belt 5 to rotate synchronously. When the pressure block 17 applies pressure to the suspension plate, so that the suspension plate and the waterproof membrane are tightly in contact for welding, the waterproof membrane can always be on the same plane under the support of the third transmission rollers 4, belt 5, and support block 6, which avoids the waterproof membrane from bending and affecting the welding effect, and effectively ensures the welding quality.

[0052] Example 3:

[0053] Reference Figures 1-11 The ultrasonic welding device for assembling waterproof membrane and suspension hook is basically the same as in Example 3, but further: a baffle plate 37 is fixedly connected to the upper end of the push plate 35 near the third piston rod 34. With the setting of the baffle plate 37, when the third piston rod 34 drives the push plate 35 to push out the lowermost suspension piece of the suspension piece storage cylinder 28, it can block the upper suspension piece, preventing the upper suspension piece from falling onto the third piston rod 34 when the push plate 35 retracts, thus causing the suspension piece to get stuck between the third air cylinder 33 and the push plate 35, making the push plate 35 unable to return to its original position, effectively ensuring the stable output of the suspension piece;

[0054] Multiple tension springs 29 are fixedly connected to the side of the support plate 27 near the pressure block 17. A buffer plate 30 is fixedly connected to the upper end of the tension spring 29. The upper surface of the buffer plate 30 is flush with the upper surface of the support plate 27. When the reciprocating telescopic cylinder 14 drives the pressure block 17 to move downward to pick up the material, the pressure block 17 can drive the buffer plate 30 to overcome the tension of the tension spring 29 and move downward a distance. Since the buffer plate 30 is in close contact with the pressure block 17 under the action of the tension spring 29, the suspension plate can be in close contact with the pressure block 17. Thus, under the action of the negative pressure component, the pressure block 17 can adsorb the suspension plate in the groove 21, which makes it easy for the pressure block 17 to stably pick up the suspension plate.

[0055] Two sets of second air cylinders 31 and second piston rods 32 are symmetrically fixedly connected to the mounting frame 1. Another set of second air cylinders 31 are symmetrically fixedly connected to both sides of the end of the mounting frame 1 away from the support plate 27. A second air box 39 is fixedly connected to the inner wall of the side of the mounting frame 1 away from the support plate 27. The second air box 39 is connected to the two adjacent second air cylinders 31 through a fourth air pipe. One-way valves are installed in the inlet and outlet of the second air cylinders 31 near the second air box 39. Multiple air jets are evenly spaced on the side of the second air box 39 near the waterproof membrane. When the rectangular frame 11 moves the support rod 12 towards the support plate 27, the support rod 12 will move the second air cylinders 31 near the second air box 39. The piston rod 32 moves, thereby drawing air into the adjacent second air cylinder 31. When the support rod 12 drives the second piston rod 32 to retract, the gas in the second air cylinder 31 is delivered into the second air box 39. Then, the gas in the second air box 39 is sprayed onto the waterproof membrane through the jet nozzle, thereby blowing air to cool the area where the waterproof membrane is connected to the suspension plate. This rapidly cools the area where the waterproof membrane is connected to the suspension plate, effectively improving the tightness between the waterproof membrane and the suspension plate. It also prevents the first drive roller 2 from contacting the area where the waterproof membrane is connected to the suspension plate, thus avoiding squeezing damage to the waterproof membrane and effectively improving the protection effect of the waterproof membrane.

[0056] Example 4:

[0057] Reference Figures 1-11 The ultrasonic welding device for assembling waterproof membrane and suspension hook is basically the same as in Example 3, but further: two sets of T-shaped rods 24 are symmetrically slidably connected on both sides of the lifting plate 15. The bottom of the T-shaped rod 24 is fixedly connected to the limit frame 26. The T-shaped rod 24 is sleeved with a tension spring 25 above the lifting plate 15. The two ends of the tension spring 25 are fixedly connected to the upper ends of the lifting plate 15 and the T-shaped rod 24, respectively. The inner walls of both sides of the rectangular frame 11 are symmetrically provided with second limiting grooves. The rack 18 is slidably connected in the second limiting groove. The second limiting groove is fixedly connected with a limit rod 41. The rack 18 is slidably connected to the limit rod 41. The two sides of the limit rod 41 are sleeved with telescopic springs 42. The two ends of the telescopic springs 42 are fixedly connected to the inner wall of the second limiting groove and the rack 18, respectively.

[0058] When the reciprocating telescopic cylinder 14 drives the ultrasonic welding machine 16 downward via the lifting plate 15, the limiting frame 26 first contacts the waterproof membrane. Then, as the ultrasonic welding machine 16 continues to move downward, the tension spring 25 is stretched under the action of the lifting plate 15. Consequently, the T-shaped rod 24 applies pressure to the limiting frame 26 under the tension of the tension spring 25, thus tensioning the area of ​​the waterproof membrane welding suspension piece. This prevents wrinkles in the waterproof membrane when the ultrasonic welding machine 16 welds the suspension piece through the pressure block 17, effectively ensuring welding stability. When the half-tooth gear 10 drives the pressure block 17 back to directly above the buffer plate 30 via the rack 18, at this time… The teeth of the half-gear 10 will mesh with the teeth on the other rack 18. Since the rack 18 is slidably connected to the limiting rod 41 and has extension springs 42 at both ends, the rack 18 will not move the rectangular frame 11 a short distance. After the pressure block 17 finishes picking up the material, the rack 18 will start to move the rectangular frame 11, so that the ultrasonic welding machine 16 and the waterproof membrane can move synchronously. By making the rack 18 slidably connected in the second limiting groove of the rectangular frame 11, when the half-gear 10 meshes with the other rack 18, the pressure block 17 can stay on the buffer plate 30 for a period of time, so that the pressure block 17 can stably pick up the suspended piece through the negative pressure component, effectively ensuring the stability of picking up the material.

[0059] This invention, through the coordinated use of the mounting frame 1, transmission unit, and conveying assembly, allows the reciprocating telescopic cylinder 14, ultrasonic welding machine 16, and pressure block 17 to move synchronously with the coil material when the external winding roller moves the coil. This ensures that the coil material, suspension plates, pressure block 17, and ultrasonic welding machine 16 remain relatively stationary during the welding process, achieving synchronous welding without stopping the machine. Compared with existing technologies, this avoids the tedious manual welding operation after the coil material is extruded, significantly saving labor costs, improving production efficiency, enhancing product quality, and strengthening brand competitiveness. Furthermore, the invention includes a suspension plate storage cylinder 28, support plate 27, negative pressure assembly, and feeding assembly. When a set of suspension plates is welded and the ultrasonic welding machine 16 and pressure block 17 retract, the suspension plates are automatically placed on the pressure block 17 without manual operation, further reducing labor costs and effectively improving welding efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
