Description

Technical field

[0001] The invention relates to the technical field of coil edge sealing equipment, in particular to coil welding edge sealing equipment. [Background Technology]

[0002] Waterproof membranes, especially ABS waterproof membranes, are widely used in waterproof construction of infrastructure, housing construction, etc. due to their excellent waterproof performance. Due to production and transportation needs, the membranes are generally made into fixed sizes. Therefore, when carrying out large-scale construction, it is often necessary to overlap and weld two adjacent membranes together. Therefore, the edge sealing at the overlap of the two membranes is particularly important for the quality control of waterproof construction.

[0003] Existing technology typically uses a simple edge-sealing device, typically a liquefied gas tank combined with a spray gun. The liquefied gas stored in the tank is sprayed through the spray gun to create a flame that heats the coiled material, thereby fusing the overlapping sections of the two coils together. This construction method and equipment presents challenges, not only in large cities where liquefied gas is difficult to obtain, but also in construction sites where open flames pose a significant safety hazard, potentially causing injury to workers and, in severe cases, fires, resulting in irreparable damage. Furthermore, manual operation based on experience makes it difficult to accurately control the amount of liquefied gas released, leading to potential leaks and excessive combustion, compromising the quality of waterproofing. [Summary of the invention]

Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figure 1 to the attached Figure 6 , this embodiment provides a coil welding and edge sealing equipment, including:

[0030] Frame 1;

[0031] Hot air component 2, provided on the frame 1, for heating the overlapping edge of the coil;

[0032] Pressing component 3, provided on the frame 1, for pressing the heated overlapping edge of the coil and welding and sealing the edge;

[0033] The traveling mechanism 4 is provided on the frame 1 and is used to drive the frame 1 to move, thereby driving the hot air component 2 and the pressing component 3 to move along the overlapping edge of the coil to heat and seal the passing coil.

[0034] For the coil welding and sealing equipment provided in this embodiment, the overlapping edge of the coil is heated by the hot air component 2, and the heated overlapping edge of the coil is pressed by the pressing component 3 and welded and sealed. There is no need for open flame operation, greatly reducing potential safety hazards. Moreover, the construction operation is simple, the degree of mechanization is high, the dependence on workers' experience is low, the temperature and speed of heating and welding are adjustable and controllable, and the welding and sealing effect is good, which is beneficial to ensuring the quality of waterproof construction.

[0035] Further, the pressing component 3 includes a pressing wheel 31. Its structure is simple, and the heated overlapping edge of the coil is pressed by the pressing wheel 31, and the operation is convenient.

[0036] Further, the pressing component 3 further includes a driving mechanism 32 for driving the pressing wheel 31 to rotate. The driving mechanism 32 drives the pressing wheel 31 to rotate, so that the moving speed of the pressing wheel 31 can be controlled more precisely, and the heating time of the hot air component 2 on the overlapping edge of the coil can be controlled more precisely, obtaining a better hot melting effect. In this embodiment, the driving mechanism 32 is a motor combined with a sprocket drive. The motor is fixed on the frame 1, the sprocket is fixed on the pressing wheel 31, and the motor drives the sprocket to rotate to drive the pressing wheel 31 to rotate. The structure is simple and the operation is convenient.

[0037] Further, the traveling mechanism 4 includes a first traveling wheel 41 and a second traveling wheel 42. The first traveling wheel 41 is located at one end of the frame 1 away from the pressing component 3, and the second traveling wheel 42 is hinged to one end of the frame 1 close to the pressing component 3, and the second traveling wheel 42 can rotate along the hinge axis to adjust the distance between the second traveling wheel 42 and the working plane. When welding and sealing are required, the second traveling wheel 42 rotates along the hinge axis to disengage from the working plane, so that the pressing wheel 31 contacts the working plane. The driving mechanism 32 drives the pressing wheel 31 to move, and the first traveling wheel 41 serves as a guiding wheel to guide the movement of the pressing wheel 31. When welding and sealing are not required, the driving mechanism 32 stops driving the pressing wheel 31, and the second traveling wheel 42 rotates along the hinge axis to contact the working plane, so that the pressing wheel 31 is kept at a distance from the working plane, avoiding the pressing wheel 31 contacting the working plane for a long time, which is beneficial to improving the service life of the pressing wheel 31. At this time, the second traveling wheel 42 serves as an auxiliary wheel to drive the coil welding and sealing equipment to move quickly together with the first traveling wheel 41. In this embodiment, the second traveling wheel 42 is a universal wheel, so as to drive the coil welding and sealing equipment to move quickly in multiple directions.

[0038] Further, the hot air component 2 includes a hot melt device 21 for the lap joint of the coil and a hot air conveying device 22 for supplying hot air to the hot melt device 21 for the lap joint of the coil. The hot melt device 21 for the lap joint of the coil includes a wind guiding and hot melting member 211 for contacting the lap joint of the coil. A hot air cavity 2111 and a plurality of hot air holes 2112 are provided on the wind guiding and hot melting member 211. The plurality of hot air holes 2112 are closely arranged. The hot air cavity 2111 is communicated with the hot air conveying device 22 so that hot air enters the hot air cavity 2111 from the hot air conveying device 22 and is discharged through the hot air holes 2112 to realize the heating and hot melting of the lap joint of the coil. In the hot air component provided in this embodiment, during operation, hot air enters the hot air cavity in the wind guiding and hot melting member through the hot air conveying device and is discharged through the hot air holes, thereby realizing the fusion welding of the lap joint of the coil. Compared with the traditional method of using a liquefied gas tank combined with a spray gun to form a simple edge sealing device for combustion heating, the present invention does not require open fire operation, greatly reduces potential safety hazards, and has high hot air efficiency and good hot melting effect.

[0039] Further, a baffle 5 is provided outside the hot air component 2 on the frame 1 to prevent an operator from accidentally touching the high-temperature hot air component 2 and causing scalding, reducing the safety risk of the equipment.

[0040] Further, a hot air outlet 2113 communicated with the hot air cavity 2111 is provided at the end of the wind guiding and hot melting member 211. In this embodiment, the end of the wind guiding and hot melting member 211 away from the pressing component 3 is the front end of the wind guiding and hot melting member 211, and the end close to the pressing component 3 is the end of the wind guiding and hot melting member 211. The hot air outlet 2113 is provided at the end of the wind guiding and hot melting member 211. After the wind guiding and hot melting member 2111 hot melts the coil, before the pressing component 3 presses the lap joint of the coil, hot air is discharged from the hot air outlet 2113, so as to promote the heated coil to remain in a hot melt state. Through the cooperation of the hot air holes 2112 and the hot air outlet 2113, a good hot melting effect is achieved.

[0041] Further, the wind guiding and hot melting member 211 includes an upper end plate and a lower end plate, and the hot air holes 2112 are provided on both the upper end plate and the lower end plate. During operation, the wind guiding and hot melting member 211 is placed between the lap joints of two coils, so that the upper end plate of the wind guiding and hot melting member 211 faces the upper coil, and the lower end plate of the wind guiding and hot melting member 211 faces the lower coil. Hot air is discharged from the hot air holes 2112 on the upper end plate and the lower end plate to heat the upper coil and the lower coil at the same time, and the hot melting efficiency is high.

[0042] Further, the thickness of the air guiding and heat melting member 211 gradually decreases from the front end to the end of the air guiding and heat melting member 211, which is beneficial to reducing the distance between the overlapping edges of the upper and lower coils after heat melting, and facilitating the fusion of the heat-melted coils together. Preferably, in this embodiment, the lower end plate of the air guiding and heat melting member 211 is parallel to the working plane, and the upper end plate of the heat conducting and welding member 211 slopes downward from the front end to the end of the air guiding and heat melting member 211, so that the thickness of the air guiding and heat melting member 211 gradually decreases from the front end to the end of the air guiding and heat melting member 211, making it more convenient to use.

[0043] Further, a notch 2114 is provided on one side of the end of the air guiding and heat melting member 211, which is beneficial to preventing the end of the air guiding and heat melting member 211 from sticking to the heat-melted coil and affecting the quality of the coil welding and sealing edge.

[0044] Further, a coil guiding member 213 is provided at the front end of the air guiding and heat melting member 211. During operation, the coil is guided to the air guiding and heat melting member 211 through the coil guiding member 213, which is beneficial to keeping the coil flat and improving the heat melting efficiency. The coil guiding member 213 includes a coil guiding wheel and a guiding wheel mounting bracket for mounting the coil guiding wheel. The lower end surface of the guiding wheel mounting bracket slopes downward from the end connected to the air guiding and heat melting member 211 to the end away from the air guiding and heat melting member 211. The upper surface of the coil guiding wheel is higher than the upper end plate of the air guiding and heat melting member 211, so that when two coils respectively placed at the upper and lower ends of the air guiding and heat melting member 211 are welded and sealed at the edge, the end far from the pressing wheel 31 maintains a certain distance from the air guiding and heat melting member 211, facilitating the hot air to be discharged from the hot air holes 2112 for heating and heat melting, and at the same time preventing the heat-melted coil from sticking to the air guiding and heat melting member 211 and blocking the hot air holes 2112, thus affecting the quality of the coil welding and sealing edge. The end of the coil at the upper end of the air guiding and heat melting member 211 close to the pressing wheel 31 is connected to the lower coil under the force of the pressing wheel 31, and the end close to the coil guiding member 213 is pressed against the lower coil under the force of the first traveling wheel 41, making it easy for the side of the end of the air guiding and heat melting member 211 far from the coil sealing edge to be close to the heat-melted coil. In this embodiment, the notch 2114 of the air guiding and heat melting member 211 is provided on the side of the end of the air guiding and heat melting member far from the coil sealing edge, which is beneficial to preventing the end of the air guiding and heat melting member 211 from sticking to the heat-melted coil and affecting the quality of the coil welding and sealing edge.

[0045] Further, the coil overlapping edge heat melting device 21 further includes a connecting member 212 provided on one side of the air guiding and heat melting member 211 and communicating with the coil overlapping edge heat melting device 21. A hot air inlet 2121 communicating with the hot air conveying device 22 is provided on the connecting member 212. The hot air enters the connecting member 212 through the hot air inlet 2121 and then enters the hot air cavity 2111 of the air guiding and heat melting member 211.

[0046] Furthermore, an installation plate 214 is provided on the connecting member 212. A strip-shaped hole 2141 is provided on the installation plate 214. The connecting member 212 is fixed to the frame 1 by connecting with the strip-shaped hole 2141 through a bolt. Thus, the coiled material lapping edge hot-melting device 21 is fixed to the frame 1. At the same time, the height of the coiled material lapping edge hot-melting device 21 relative to the working plane can be adjusted by adjusting the matching position of the bolt and the strip-shaped hole 2141, which is convenient to adjust and more convenient to use.

[0047] Furthermore, the lower end surface of the connecting member 212 is inclined upward from the end connected to the air-guiding hot-melting member 211 to the end far away from the air-guiding hot-melting member 211. Since the heat of the hot air is easily transferred to the connecting member 212 when passing through the inner cavity of the connecting member 212, the heated connecting member 212 is likely to transfer the heat to the coiled material at the lower end during the movement along with the air-guiding hot-melting member 211, causing the coiled material to be hot-melted. In this embodiment, the lower end surface of the connecting member 212 is inclined upward from the end connected to the air-guiding hot-melting member 211 to the end far away from the air-guiding hot-melting member 211, which can effectively prevent the heat of the connecting member 212 from being transferred to the coiled material and causing unnecessary hot-melting of the corresponding coiled material, and is beneficial to ensuring the quality of the waterproof construction.

[0048] Furthermore, the hot air conveying device 22 includes a heating mechanism 221 for heating air to form hot air, and an air extraction mechanism 222 for driving air into the heating mechanism 221 and conveying the hot air formed in the heating mechanism 221 to the hot air inlet 2121. One end of the heating mechanism 221 is connected to the hot air inlet 2121, and the other end is connected to the air extraction mechanism 222. The structure is simple and the hot air conveying effect is good.

[0049] Furthermore, the heating mechanism 221 includes a heating mechanism body 2211. A ventilation hole 2212 is provided in the heating mechanism body 2211, and a heating element 2213 is provided in the ventilation hole 2212. In this embodiment, the number of the ventilation holes 2212 is multiple, and the multiple ventilation holes 2212 are arranged in a honeycomb shape in the heating mechanism body 2211. Each ventilation hole 2212 is correspondingly provided with the heating element 2213. The heating element 2213 used in this embodiment is a heating wire, and the heating mechanism body 2211 used is made of ceramic material. When the air extraction mechanism 222 drives air through the ventilation hole 2212, the heating element 2213 heats the air, with high heating efficiency, quickly forming hot air and conveying it to the hot air inlet 2121, then entering the hot air cavity 2111, and finally being discharged through the hot air holes 2112 to heat the coiled material, achieving a good hot-melting effect.

[0050] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention.
