Description

Technical Field

[0001] The present application relates to the technical field of foaming agent filling, and in particular to a fusing mechanism, a foaming agent filling device and a filling method. Background Art

[0002] Polyurethane foam filler is a specialized polyurethane product containing a polyurethane prepolymer, a blowing agent, and a catalyst in a pressure-resistant aerosol can. When the material is sprayed from the can, the foamy polyurethane rapidly expands and solidifies with the air or moisture in the substrate it comes into contact with, forming a foam. The cured foam provides various benefits, including caulking, bonding, sealing, thermal insulation, and sound absorption. It is an environmentally friendly, energy-saving, and easy-to-use building material suitable for sealing leaks, filling gaps, fixing bonds, and providing thermal insulation and sound insulation. It is particularly suitable for sealing and waterproofing between plastic-steel or aluminum alloy doors and windows and walls.

[0003] At present, a Chinese utility model application with a publication date of July 12, 2022 and publication number CN216942075U proposes an H-shaped paper strip forming device for a polyurethane foaming machine, comprising a feeding device, a forming device and a traction member arranged in sequence on a frame, characterized in that the forming device comprises an upper forming roller, which is rotatably arranged on the frame, and has arc-shaped bosses on both sides of the upper forming roller, and a lower forming roller, which is rotatably arranged on the frame and is located below the upper forming roller, and the lower forming roller has a first groove, and the upper forming roller abuts against the inner wall of the first groove, and the arc-shaped groove is arranged on both sides of the bottom of the first groove, and the boss abuts against the arc-shaped groove, and is pressed into an H-shaped paper strip by the forming device, and then sent into the interior of the filling profile through the traction member via the guide member.

[0004] With regard to the relevant technologies in the above-mentioned documents, the inventor believes that, in this design, a shaping mechanism and a conveying mechanism for the H-shaped paper strips are designed, but there is no equipment for how to cut the H-shaped paper strips after the conveying is completed. Assuming that the H-shaped paper strips are cut manually after the conveying is completed, due to the particularity of the H-shaped paper strips, some foaming agent will overflow outside the profile. When the manual cutting operation is performed, this part of the foaming agent will be wasted and the ground will be polluted, resulting in unnecessary cleaning costs in the later stage. Summary of the Invention

[0005] In order to improve the working efficiency of the foaming agent filling equipment, the purpose of this application is to provide a fusing mechanism, a foaming agent filling equipment and a filling method.

[0006] To achieve the above objectives, in a first aspect, the present application provides a fuse mechanism, which adopts the following technical solution:

[0007] A fuse mechanism comprises a clamping mechanism and a supporting mechanism, the clamping mechanism comprises an upper fuse frame, a pressure block is connected in the middle of the upper fuse frame, a conical block is connected below the pressure block, the supporting mechanism comprises a lower fuse rear frame, a fuse base plate is fixedly installed on the lower fuse rear frame, a lower fuse front frame is fixedly installed in the middle below the fuse base plate, an oblique support block is fixedly connected to the fuse base plate, a coil mounting groove is provided at the upper end of the rear side of the oblique support block, a raised strip is fixedly installed on the high point of the oblique support block, a fuse coil is fixedly installed on the top of the coil mounting groove, a guide groove is provided on the oblique support block, the top of the guide groove is close to the raised strip, a guide member is fixedly installed at the front end of the fuse base plate, and the guide member is close to the bottom end of the oblique support block, the fuse mechanism also comprises an upper fuse transmission mechanism and a lower fuse transmission mechanism.

[0008] By adopting the above scheme, the fusing mechanism is lifted and lowered by the fusing upper transmission mechanism and the fusing lower transmission mechanism, the foaming bag is pressed against the raised strip by the conical block, the raised strip is heated by the fusing coil so that the temperature of the raised strip reaches a temperature capable of melting the foaming bag, and at the same time, the viscosity generated when the foaming bag is melted is used to seal the two ends of the melt, making cutting easier. At the same time, the sealing process also avoids waste of foaming agent.

[0009] Optionally, the upper fuse transmission mechanism includes a first drive mechanism and a first slide rail, the first motor drive mechanism is slidably connected to the upper fuse frame, the lower fuse transmission mechanism includes a second drive mechanism and a second slide rail, the second drive mechanism is slidably connected to the lower fuse rear frame, the first slide rail is slidably connected to both ends of the upper fuse frame, and the second slide rail is slidably connected to both ends of the lower fuse rear frame and the lower fuse front frame.

[0010] By adopting the above solution, the first slide rail and the second slide rail cooperate with the upper fuse transmission mechanism and the lower fuse transmission mechanism to provide guidance and support assistance for the movement of the fuse mechanism, so that the fuse mechanism can operate more stably while obtaining sufficient support, and solves the problem of the position of the conical block and the raised strip being offset due to the excessively fast lifting speed during the lifting process.

[0011] Optionally, the width of the raised strip is greater than the width of the lower side of the conical block, and the depth of the guide groove is greater than the radius of the foaming bag.

[0012] By adopting the above solution, the lower side width of the conical block is 2mm, the width of the raised strip is 5mm, and the depth of the guide groove is 4mm. The width of the raised strip is greater than the width of the lower side of the conical block, so that the contact area between the raised strip and the conical block is larger during melting. At the same time, in the event of a slight mechanical deviation, the melting effect is not affected. The depth of the guide groove is greater than the radius of the foaming bag, so that the foaming bag does not fall out of the guide groove when moving and fall.

[0013] In a second aspect, the present application provides a foaming agent filling device, which adopts the following technical solution:

[0014] A foaming agent filling device includes a mounting frame and a fuse mechanism.

A foaming agent filling mechanism is fixedly mounted on the rear end of the base plate, and the foaming agent filling mechanism is connected to a foaming bag transfer tube. The front end of the foaming bag transfer tube passes through the back plate of the mounting frame and is close to the rear end of the fuse mechanism. A foaming bag is sleeved on the foaming bag transfer tube. The foaming bag is injected into the profile through the fuse mechanism and the conveying mechanism. A linear module mechanism is fixedly installed on the upper outer side of the front of the mounting frame, a cutting mechanism is installed on one side of the front of the linear module mechanism, and an air injection mechanism is installed on the other side of the front of the linear module mechanism. The air injection mechanism includes a pen-shaped electric cylinder, the front end of the pen-shaped electric cylinder is fixedly connected to a needle fixing block, the front end of the needle fixing block is fixedly installed with a needle buckle, and an air injection needle is fixedly connected inside the needle buckle. The front end of the air injection needle is an oblique surface, and the electrical signals of the fusing mechanism, conveying mechanism, linear module mechanism, cutting mechanism, air injection mechanism and foaming agent filling mechanism are connected to a controller.

[0015] By adopting the above solution, the bevel design at the front end of the injection needle allows the needle to be easily inserted into the elbow cover, making injection faster. The injection needle is fixed by the needle buckle, so that the injection needle is firmly fixed, reducing the bending of the injection needle when inserting into the elbow cover, thereby reducing the probability of damage to the injection needle.

[0016] Optionally, the mounting frame includes an outer support plate and an inner vertical plate, the outer support plate and the top plate are fixedly installed on the top of the inner vertical plate, the front vertical plate is fixedly installed in the middle of the inner vertical plate, the support plate is fixedly installed in the middle of the front vertical plate, the bottom of the support plate is fixedly installed with a reinforcing rib connected to the front vertical plate, the top of the support plate is fixedly connected to a guide limit groove, the tail end of the guide limit groove is close to the conveying mechanism, the foam bag is slidably placed on the guide limit groove, and the first slide rail and the second slide rail are fixedly installed on the rear of the inner vertical plate.

[0017] By adopting the above solution, the outer support plate, the inner vertical plate and the top plate are connected into one, making the frame more solid, the support plate supports the guide limit groove, and the reinforcing ribs support the support plate, so that the support plate and the guide limit groove are more firmly fixed on the front vertical plate, avoiding the support plate and the guide limit groove from falling due to long-term use, thereby affecting the conveying effect of the foam bag.

[0018] Optionally, the conveying mechanism includes an active conveying mechanism and a driven conveying mechanism, the active conveying mechanism includes a main conveying shaft, one side of the main conveying shaft is connected to the conveying motor, the middle of the main conveying shaft is fixedly connected to the main conveying wheel, the driven conveying mechanism includes a driven conveying shaft, one side of the driven conveying shaft is connected to the lifting connecting seat, the side of the driven conveying shaft away from the lifting connecting seat is connected to the driven shaft slide, the middle of the driven conveying shaft is slidably connected to the driven conveying wheel, the lifting connecting seat is connected to the driven shaft lifting mechanism, the lifting connecting seat and the driven shaft slide are slidably connected to the third slide rail, the driven shaft lifting mechanism includes a lifting motor and a lifting screw, the front end of the lifting motor is connected to the first cone Gear, the lifting screw is slidably connected to the inner vertical plate on one side, the lifting screw is slidably connected to the driven shaft slide, the top of the lifting screw is connected to the second bevel gear, the first bevel gear and the second bevel gear are meshed, the main conveying wheel and the outer ring of the driven conveying wheel are connected to the rubber wheel rim, the main conveying wheel and the driven conveying wheel are slidably connected to the foaming bag in the middle, the active conveying mechanism and the driven conveying mechanism are connected to the front end of the inner vertical plate, the third slide rail is fixedly installed on the front part of the inner vertical plate, the conveying motor is fixedly installed on one side of the front of the inner vertical plate, the main conveying wheel shaft is slidably connected to the inner vertical plate away from the conveying motor, and the lifting motor is fixedly installed on the top plate.

[0019] By adopting the above solution, the lifting motor and the lifting screw cooperate to complete the lifting and lowering of the driven conveying mechanism, thereby adjusting the distance between the main conveying wheel and the driven conveying wheel. The rubber wheel rim increases the friction, making the conveying of the foam bag smoother, and avoiding the problem of insufficient friction between the contact surface between the foam bag and the active conveying mechanism and the driven conveying mechanism.

[0020] Optionally, the linear module mechanism includes a linear module, a module connecting plate is fixedly installed on the front of the linear module, a cutting mounting plate is fixedly installed on one side of the front of the module connecting plate, an air injection mounting plate is fixedly installed on the side of the front of the module connecting plate away from the cutting mounting plate, the air injection mounting plate is fixedly installed on the pen-type electric cylinder, and the cutting mechanism includes a cutting motor, the cutting motor is fixedly installed on the cutting mounting plate, and the front end of the cutting motor is fixedly connected to the cutting knife.

[0021] By adopting the above solution, the linear module provides power for the lifting and lowering of the cutting mechanism and the gas injection mechanism, and the cutting force of the cutting knife is controlled by controlling the speed of the cutting motor. The cutting depth of the foaming bag is the thickness of the foaming bag wall, which is convenient for filling the interior of the aluminum profile when the foaming agent is foaming, avoiding excessive foaming force that may cause the foaming agent to burst.

[0022] Optionally, the foam bag includes a foam bag body, a filling area and an air injection area are arranged inside the foam bag body, a diaphragm is arranged between the filling area and the air injection area, an air inlet elbow is arranged on the outer side of the tail end of the foam bag body close to the diaphragm, and the front end of the air inlet elbow is connected to the elbow cover.

[0023] By adopting the above solution, the foam bag is made of degradable material, the filling area is used to fill the foaming agent, the gas injection area is used to inject carbon dioxide gas, the diaphragm thickness is 0.2mm, and the diaphragm is arranged at a position 0.3mm away from the inner wall of the foam bag on the side close to the air inlet elbow. The elbow cover is used to prevent carbon dioxide leakage during the gas injection process. Using a foam bag instead of the original H-shaped paper strip effectively avoids the problem of excessive filling and leakage of the foaming agent, and water vapor may be generated inside the profile or the conveying equipment after a period of time. If the H-shaped paper strip encounters water vapor, it is easy to break, which will cause the foaming agent to be unable to be completely filled into the profile. Using a foam bag can effectively avoid this situation.

[0024] Optionally, an air supply mechanism is installed on the base plate near the side of the mounting frame, and the air supply mechanism includes a fixed base, an air supply tank is placed on the fixed base, a fixing strap is connected to the fixed base, and the air supply tank is connected to the air injection needle through an air pipe.

[0025] By adopting the above solution, the lower half of the fixed base is the supporting leg, and the upper half is the arc-shaped placing table. The gas tank is placed on the arc-shaped placing table. The fixing straps are fixedly installed on the outside of the arc-shaped placing table. The fixing straps are used to fix the gas tank, and the gas tank is filled with carbon dioxide gas.

[0026] In a third aspect, the present application provides a foaming agent filling method, which adopts the following technical solution:

[0027] A foaming agent filling method comprises the following steps:

[0028] Position adjustment: manually adjust the position of the fuse lower transmission mechanism and the driven shaft lifting mechanism through the controller to ensure that the upper surface of the raised strip fits the foam bag, and by adjusting the driven shaft lifting mechanism, the radius between the active conveying mechanism and the driven conveying mechanism is consistent with the radius of the foam bag;

[0029] Filling and conveying: The foaming agent filling equipment fills the foaming agent into the foam bag filling area. The filled foam bag passes through the oblique support block and enters between the active conveying mechanism and the driven conveying mechanism. The conveying motor is started to drive the main conveying wheel to rotate in the reverse direction, driving the foam bag to move forward through the guide limit groove and enter the interior of the profile.

[0030] Melt and seal, stop the foaming agent injection, start the fusing coil, heat the raised strip, and at the same time press the conical block down through the upper fusing transmission mechanism to press the foam bag tightly onto the raised strip. The foam bag is melted by high heat and the melted part is sealed at the same time.

[0031] Cutting: When the sealing part of the foam bag is close to the end of the guide limit groove, the linear module mechanism is started, the cutting mechanism is lowered, and the surface of the foam bag is cut. The cutting depth is the thickness of the foam bag wall, and the cutting length is 5mm. After the cutting is completed, the linear module mechanism returns to the initial position;

[0032] Gas injection: When all the foaming bags are sent into the profile, start the linear module mechanism, lower the gas injection needle in the gas injection mechanism to a position horizontal to the center of the gas inlet elbow of the foaming bag, start the pen-shaped electric cylinder, insert the gas injection needle into the gas inlet elbow, open the air valve of the gas supply tank, and inject gas into the gas injection area of ​​the foaming bag until the diaphragm inside the foaming bag ruptures. Stop gas injection, the pen-shaped electric cylinder shrinks to its initial position, the linear module mechanism returns to its initial position, and the gas inlet elbow is unplugged;

[0033] Foaming: Let the profile stand still to allow the injected gas to fuse with the foaming agent and then foam. After the foaming agent foams, it overflows from the cut and the foaming bag is torn at the same time, so that the foaming agent fills the internal area of ​​the profile.

[0034] By adopting the above scheme, position adjustment can ensure that the foam bag can smoothly enter the subsequent position during the conveying process. After the adjustment is completed, the foaming agent filling equipment is started to fill the filling area of ​​the foam bag, and the conveying motor is started at the same time to convey the foam bag and convey the filled foam bag to the inside of the profile. When the filling is completed, the upper transmission mechanism of the fuse is started to make the pressing mechanism press the foam bag on the raised strip, and the fuse coil is started to heat the raised strip to melt and seal the foam bag. When the foam bag after melting is conveyed to the front end of the guide limit slot, the linear module and the cutting motor are started at the same time to drive the cutting knife to descend and cut the surface of the foam bag. Cut a small hole with a length of 5mm. After cutting, feed the last section of the foaming bag into the profile, start the linear module again, align the air injection needle with the center of the air inlet elbow, start the pen-shaped electric cylinder, insert the air injection needle into the elbow cover, open the air inlet valve of the air supply tank, and inject air into the air injection area of ​​the foaming bag until the diaphragm ruptures and the injected carbon dioxide and the foaming agent are fused. Retract the air injection needle, return the linear module to the initial position, unplug the air inlet elbow, and finally let the profile stand. When the injected carbon dioxide and the foaming agent are completely fused, foaming is carried out. The above filling method makes the foaming agent filling effect inside the aluminum profile better and the foaming more complete.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1. This application uses a fusing mechanism to fuse the foaming bag, thereby solving the problem of manual cutting of H-shaped paper strips, which causes waste of foaming agent and impacts the surrounding environment, and eliminates unnecessary cleaning costs. At the same time, the fusing mechanism itself seals the foaming bag to prevent the foaming agent inside from prematurely foaming due to premature contact with air, which would lead to unsatisfactory foaming results or foaming agent overflow.

[0037] 2. This equipment injects carbon dioxide gas into the foaming bag through the gas injection mechanism. The fusion of carbon dioxide and foaming agent increases the foaming speed, shortens the foaming time, and improves the foaming efficiency.

[0038] 3. The foaming bags in this equipment are made of degradable materials. After foaming, the foaming bags will completely degrade over time to avoid harm to the environment. At the same time, the front end of the air inlet elbow is sealed with an elbow cover to prevent carbon dioxide from overflowing during the gas injection process, avoiding harm to the surrounding environment and personnel.

[0039] 4. This equipment improves the efficiency of filling the foaming agent inside the profile through the combination of the fusing mechanism, the conveying mechanism, the cutting mechanism and the gas injection mechanism. At the same time, it solves the problem of foaming agent waste after the H-shaped paper strip is conveyed into the profile. In addition, by injecting carbon dioxide gas, the foaming time of the foaming agent is shortened and the foaming is made more uniform, avoiding the incomplete foaming caused by external air during foaming.

[0062] The implementation principle of the foaming agent filling device in the embodiment of the present application is:

[0063] Each mechanism is controlled by a controller, and the operating status of each mechanism is known through the feedback of the sensor signal of each mechanism. First, the foaming agent filling mechanism 1000 is started to fill the filling area 712 of the foaming bag 700. The filled foaming bag 700 slides along the support mechanism 240 into the conveying mechanism 300, and the conveying motor 311 is started to make the main conveying wheel 313 rotate counterclockwise to bring the foaming bag 700 into the middle of the conveying mechanism 300. The driven conveying wheel 324 rotates counterclockwise with the main conveying wheel 313 to bring the foaming bag 700 into the middle of the conveying mechanism 300. The bag 700 is conveyed into the guide limit groove 170, and the foaming bag 700 enters the interior of the profile through the guide limit groove 170. When the sensor of the fusing mechanism 200 detects the elbow cover 730, the controller stops the filling of the foaming agent filling mechanism 1000 and the operation of the conveying motor 311, starts the fusing upper transmission mechanism 210, and causes the pressing mechanism 220 to descend. The foaming bag 700 is pressed against the raised strip 244 through the conical block 223, and the fusing coil 245 is started to heat the raised strip 244, so that the two sides of the raised strip 244 are The foam bag 700 is melted and sealed, and then the conveying motor 311 is restarted to send the remaining foam bag 700 to the guide limit groove 170. When the tail of the foam bag 700 approaches the front end of the guide limit groove 170, the conveying motor 311 is stopped, the linear module 410 is started, and the cutting mechanism 500 is lowered to the foam bag 700. The cutting motor 510 is started to drive the cutting knife 520 to cut the surface of the foam bag 700. After the cutting is completed, the linear module 410 drives the cutting mechanism 500 to return to the initial position and the conveying is started. The motor 311 sends the remaining part into the interior of the profile, starts the linear module 410, aligns the gas injection needle 630 with the center of the elbow cover 730, starts the pen-shaped electric cylinder 610, inserts the gas injection needle 630 into the elbow cover 730, opens the gas supply valve of the gas supply tank 820, and injects gas into the gas injection area 711 of the foaming bag 700 until the diaphragm 713 ruptures. After the gas injection is completed, the pen-shaped electric cylinder 610 is recovered, the linear module 410 returns to the initial position, unplug the air inlet elbow 720, and seal the unplugged position to prevent carbon dioxide gas and foaming agent from overflowing.

[0064] Example 2:

[0065] The present application discloses a foaming agent filling method, referring to Figure 11 , including the following steps:

[0066] S1: Position adjustment. The position of the lower fuse transmission mechanism 230 and the driven shaft lifting mechanism 330 is manually adjusted and positioned through the controller to ensure that the upper surface of the raised strip 244 is in contact with the foam bag 700, and the radius between the active conveying mechanism 310 and the driven conveying mechanism 320 is made consistent with the radius of the foam bag 700 by adjusting the driven shaft lifting mechanism 330. The support mechanism 240 is lifted by the lower fuse transmission mechanism 230, and the position signal is transmitted by the sensor until the position of the raised strip 244 coincides with the lower surface of the foam bag 700. The lifting motor 331 drives the lifting screw 334 to move, and at the same time drives the driven shaft slide 322 connected to the lifting screw 334 to descend, so that the distance between the main conveying wheel 313 and the driven conveying wheel 324 is equal to the diameter of the foam bag 700. The linear module 410 and the pen-type electric cylinder 610 are all in zero position as the initial position;

[0067] S2: Filling and conveying. The foaming agent filling device fills the foaming agent into the filling area 712 of the foam bag 700. The filled foam bag 700 passes through the oblique support block 243 and enters between the active conveying mechanism 310 and the driven conveying mechanism 320. The conveying motor 311 is started to drive the main conveying wheel 313 to rotate in the opposite direction, driving the foam bag 700 to move forward through the guide limit groove 170 and enter the interior of the profile. The foam bag 700 slides down from the guide groove 2432 of the oblique support block 243 and enters In the middle of the conveying mechanism 300, the main conveying wheel 313 drives the foaming bag 700 to continue to move forward, and the driven conveying wheel 324 rotates counterclockwise following the main conveying wheel 313.

The foaming bag 700 passing through the conveying mechanism 300 is conveyed to the guide limit groove 170. Finally, after leaving the conveying mechanism 300, the thrust of the subsequent foaming agent injection is used to push the remaining part into the profile.

The cutting depth is equal to the wall thickness of the foam bag 700, and the length of the cut is 5 mm. After the cutting is completed, the linear module mechanism 400 returns to the initial position. During the cutting process, the foam bag 700 maintains a low speed movement, so that a 5 mm long cut is formed on the surface of the foam bag 700.

[0070] S5: Gas injection. After all the foaming bags 700 are fed into the profile, the linear module mechanism 400 is started, and the gas injection needle 630 in the gas injection mechanism 600 is lowered to a position horizontal to the center of the gas inlet elbow 720 of the foaming bag 700. The pen-shaped electric cylinder 610 is started, and the gas injection needle 630 is inserted into the gas inlet elbow 720. The air valve of the gas supply tank 820 is opened, and the carbon dioxide gas in the gas supply tank 820 enters the gas inlet elbow 720 through the air pipe to inject gas into the gas injection area 711 of the foaming bag 700 until the diaphragm 713 inside the foaming bag 700 ruptures. The gas injection is stopped, the pen-shaped electric cylinder 610 is retracted to the initial position, the linear module mechanism 400 returns to the initial position, and the gas inlet elbow 720 is unplugged. The position after the gas inlet elbow 720 is unplugged is sealed with sealing tape to prevent leakage of carbon dioxide gas and foaming agent.

[0071] S6: Foaming: The profile is left to stand to allow the injected gas to fuse with the foaming agent and then foam. After foaming, the foaming agent overflows from the cut and simultaneously tears the foaming bag 700 so that the foaming agent fills the interior area of ​​the profile.

After completion, start the foaming agent filling device to fill the filling area 712 of the foam bag 700. At the same time, start the conveying motor 311 to convey the foam bag 700 and convey the filled foam bag 700 to the inside of the profile. When filling is completed, start the upper fuse transmission mechanism 210 to make the pressing mechanism 220 press the foam bag 700 on the raised strip 244, start the fuse coil 245 to heat the raised strip 244, and fuse and seal the foam bag 700. When the foam bag 700 after melting is conveyed to the front end of the guide limit groove 170, the linear module 410 and the cutting motor 510 At the same time, it is started, driving the cutting knife 520 to descend and cut the surface of the foaming bag 700, cutting a small hole with a length of 5 mm.

The gas injection needle 630 is aligned with the center of the circle of the air inlet elbow 720, and the pen-shaped electric cylinder 610 is started. The gas injection needle 630 is inserted into the elbow cover 730, and the air inlet valve of the air supply tank 820 is opened. The gas injection area 711 of the foaming bag 700 is injected with gas until the diaphragm 713 breaks and the injected carbon dioxide and the foaming agent are fused. The gas injection needle 630 is retracted, the linear module 410 returns to the initial position, the air inlet elbow 720 is pulled out, and finally the profile is left to stand. When the injected carbon dioxide and the foaming agent are completely fused, foaming is carried out.
