Description

Technical Field

[0001] The invention relates to the technical field of building waterproof construction equipment, in particular to a semi-automatic flame edge sealing machine. Background Art

[0002] At present, in the construction of building projects, modified asphalt waterproofing membranes are widely used in roof waterproofing and basement roof waterproofing. In the process of modified asphalt waterproofing membrane construction, after the waterproofing membrane is laid, it needs to be hot-melt sealed before entering the water storage test stage.

[0003] In the existing technology, the construction method of modified asphalt waterproofing membrane is as follows: one person holds a flamethrower connected to a gas tank through an air pipe. After the flame from the flamethrower softens the asphalt waterproofing membrane, another person holds a driving wheel and rolls the driving wheel on the asphalt waterproofing membrane to press out molten slurry from the overlapping edges, thereby fixing the modified asphalt waterproofing membrane on the roof.

[0004] The above-mentioned existing technical solutions have the following defects: two people are required to cooperate in the edge sealing of the modified asphalt waterproofing membrane, which is time-consuming and labor-intensive, requires a lot of labor, and has extremely low work efficiency. In addition, the length of the gas pipe connected to the spray gun is limited, and the gas tank needs to be moved continuously, which is cumbersome to operate and has great safety hazards. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a semi-automatic flame edge banding machine, which can be independently operated by one person to lay modified asphalt waterproof membrane. The driving wheel is driven by electric power assistance to rotate, so as to realize the smoothing and pressing of the overlapping edges of the modified asphalt waterproof membrane, which saves time and labor, is simple to operate, and improves the efficiency and safety of construction.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A semi-automatic flame edge banding machine comprises a movable bracket, an anti-flashback valve, a gas tank and a hand-held pneumatic walking flame gun, wherein the gas tank is detachably fixed in the bracket, and the gas tank is connected to the hand-held pneumatic walking flame gun through a gas pipe and the anti-flashback valve;

[0008] The handheld pneumatic walking flame gun is provided with a flame controller, an air inlet pipe, an air outlet pipe, a driving motor and a power module, the power module is electrically connected to the driving motor and the flame controller respectively, the driving motor is connected to the flame controller, a flame nozzle connected to the air pipe is installed at one end of the handheld pneumatic walking flame gun, and a driving wheel is installed at the other end, and a supporting part for lifting the edge of the coil is installed on the flame nozzle;

[0009] The handheld pneumatic walking flame gun is fixedly connected to a mounting tube, a transmission rod is arranged in the mounting tube, one end of the transmission rod is fixedly connected to the output shaft of the driving motor, and the other end is drivingly connected to the driving wheel, the driving motor is connected to the flame controller, and the driving wheel and the flame nozzle are located on the same horizontal plane.

[0010] Through the above technical solution, during construction, the support part is inserted under the waterproofing membrane to support the overlapping edge, the power module is turned on to power the drive motor and the flame controller, and the flame nozzle sprays flames to spray the overlapping seams of the waterproofing membrane. The operator holds a handheld pneumatic walking flame gun with one hand and pushes the bracket with the other hand. The driving motor assists the driving wheel to rotate. The rotation of the driving wheel presses the overlapping seams of the waterproofing membrane. The advancement speed of the flat membrane hot-melt edge sealing machine is controlled according to the melting speed of the flame sprayed membrane to ensure the quality of the hot-melt edge sealing of the membrane. One person can independently operate the whole process to lay the modified asphalt waterproofing membrane. The electric power assist drives the driving wheel to rotate to achieve the smearing and pressing of the overlapping edges of the modified asphalt waterproofing membrane, which saves time and effort, is simple to operate, and improves the efficiency and safety of construction.

[0011] In a preferred example, the present invention can be further configured as follows: the handheld pneumatic walking flame gun is provided with a flame control button and a driving motor rotation button connected to the flame controller.

[0012] Through the above technical solution, the size of the flame of the flame nozzle can be adjusted by pressing the flame control button, and the driving motor rotation button is pressed to drive the driving motor to drive the transmission rod to rotate, thereby realizing the rotation of the driving wheel, achieving electric power assistance, and improving the laying efficiency of the waterproof membrane.

[0013] In a preferred example, the present invention can be further configured as follows: one end of the handheld pneumatic walking flame gun is fixedly connected to a base, a sliding rod is provided on the base, and the extending direction of the sliding rod is parallel to the rotating shaft of the driving wheel;

[0014] One end of the flame spray nozzle is fixedly connected with a sliding block, the sliding block is rotatably sleeved on the sliding rod and has an interference fit with the sliding rod, and the flame outlet of the flame spray nozzle is consistent with one of the extension directions of the sliding rod along its length.

[0015] Through the above technical solution, when laying the waterproofing coiled material, the sliding block is pushed to make it close to the edge of the coiled material overlap seam, and then the flame spraying nozzle is rotated to be inserted in the middle of the coiled material overlap edge to spray fire, and the driving wheel presses it after the coiled material melts. When the flame spraying is not needed, the sliding block is directly pushed away from the coiled material overlap edge, so that the flame spraying nozzle can be moved out from the coiled material overlap edge, thereby improving practicality.

[0016] In a preferred example, the present invention can be further configured as follows: the flame outlet of the flame spray nozzle is flattened.

[0017] Through the above technical solution, the flattened flame nozzle makes the flames uniform and more suitable for the overlapping edges of the roll materials. After the roll materials are heated evenly, the bonding strength is improved, thereby enhancing the laying effect of the waterproof roll materials.

[0018] In a preferred example, the present invention can be further configured as follows: the supporting portion includes a rotating ring, a connecting rod and a limiting rod, the rotating ring is rotatably connected to the side wall of the flamethrower, one end of the connecting rod is hingedly connected to the rotating ring, and the other end is hingedly connected to the limiting rod;

[0019] A slide groove is provided on the flame spray nozzle, and limiting grooves are provided on two inner side walls of the slide groove. The limiting rod is slidably arranged between the two limiting grooves, and an elastic clamping piece for fixing the limiting rod is arranged inside the limiting rod.

[0020] Through the above technical solution, when laying the waterproof coiled material, the rotating ring is rotated to tilt it to a certain angle, so as to facilitate lifting the overlapping edge of the waterproof coiled material, and the connecting rod is fixed by adjusting the elastic clamping piece, thereby ensuring the stability of the tilting of the rotating ring, and facilitating the continuous laying of the waterproof coiled material. After the laying work is completed, the elastic clamping piece is adjusted to make the connecting rod overlap above the flame-throwing nozzle. Due to the supporting effect of the connecting rod, the extending direction of the rotating ring is consistent with that of the flame-throwing nozzle, which is convenient for storage and arrangement, and improves practicality.

[0021] In a preferred example, the present invention can be further configured as follows: the elastic clip includes a spring arranged in the limiting rod and a clip ball respectively fixedly connected to both ends of the spring, and the bottoms of the two limiting grooves are respectively provided with a plurality of mutually aligned clip grooves, and the clip ball is elastically embedded in the clip groove.

[0022] Through the above technical solution, the limit rod is pushed to slide in the limit groove, and the sliding of the limit rod drives the connecting rod, and the connecting rod drives the rotating ring to rotate within a certain angle range, thereby realizing the adjustment of the lifting angle of the rotating ring. When the limit rod slides, the spring inside it is compressed and tightened to accumulate elastic force. When it needs to be fixed, the limit rod is slid to the position of the clamping groove, and the spring naturally recovers to provide power to drive the clamping ball to be clamped in the clamping groove, thereby realizing the fixation of the limit rod and the connecting rod, which is convenient for the rotating ring to stably lift the overlapping edge of the coil. When the rotating ring needs to be retracted, it is only necessary to push the limit rod horizontally, the spring is compressed and tightened, and the clamping ball shrinks in the limit rod, which is convenient for moving the limit rod and improves practicality.

[0023] In a preferred example, the present invention can be further configured as follows: a reinforcing rod is fixedly connected to the handheld pneumatic walking flame gun.

[0024] Through the above technical solution, the provision of the reinforcing rod increases the structural strength of the handheld pneumatic walking flame gun, thereby extending the service life of the semi-automatic flame edge banding machine.

[0025] In a preferred example, the present invention can be further configured as follows: a plurality of screw rods are threadedly connected to the side wall of the bracket, and an arc-shaped plate is fixedly connected to one end of the screw rod close to the gas tank.

[0026] Through the above technical solution, the screw is rotated to drive the arc plate to move closer to or away from the gas tank. When the screw is tightened, the arc plate is attached to and pressed against the outer wall of the gas tank. The mutual cooperation of multiple screws realizes the fixation of the gas tank on the bracket, which improves the stability of the coil laying work. At the same time, the simple setting of the screw and the arc plate enables the bracket to fix gas tanks of different sizes, thereby improving the practicality of the entire device.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. During construction, insert the support part under the waterproofing membrane to support the overlapping edge, turn on the power module to power the drive motor and the flame controller, and the flame nozzle sprays flames to spray the overlapping seams of the waterproofing membrane.

The rotation of the driving wheel presses the overlapping seams of the waterproofing membrane. The advancement speed of the flat membrane hot-melt edge sealing machine is controlled according to the melting speed of the flame sprayed membrane to ensure the quality of the hot-melt edge sealing of the membrane. One person can independently operate the whole process to lay the modified asphalt waterproofing membrane. The electric power assist drives the driving wheel to rotate to achieve the smearing and pressing of the overlapping edges of the modified asphalt waterproofing membrane, which saves time and effort, is simple to operate, and improves the efficiency and safety of construction.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] Reference Figure 1 , is a semi-automatic flame edge banding machine disclosed in the present invention, comprising a movable bracket 1, an anti-backfire valve, a gas tank 2 and a handheld pneumatic walking flame gun 3. The gas tank 2 can be detachably fixed in the bracket 1, and the gas tank 2 is connected to the handheld pneumatic walking flame gun 3 through an air pipe 21 and an anti-backfire valve. The handheld pneumatic walking flame gun 3 is provided with a flame controller, an air inlet pipe, an air outlet pipe, a driving motor 31 and a power module 32. The power module 32 is electrically connected to the driving motor 31 and the flame controller respectively. The driving motor 31 is connected to the flame controller. A flame nozzle 33 connected to the air pipe 21 is installed at one end of the handheld pneumatic walking flame gun 3, and a driving wheel 34 is installed at the other end. A supporting part 4 for lifting the edge of the coil is installed on the flame nozzle 33.

[0038] Among them, the driving motor 31 can also be configured as a pneumatic driving motor, which is driven by the gas pressure itself. The motor drives the driving wheel to rotate, thereby realizing the smoothing and pressing of the overlapping edges of the modified asphalt waterproofing membrane, saving time and effort, and being simple to operate, thereby improving the efficiency and safety of construction.

[0039] A mounting tube 35 is fixedly connected to the handheld pneumatic walking flame gun 3, and a transmission rod 36 is arranged in the mounting tube 35. One end of the transmission rod 36 is fixedly connected to the output shaft of the driving motor 31, and the other end is transmission-connected to the driving wheel 34. The driving motor 31 is connected to the flame controller, and the driving wheel 34 and the flamethrower 33 are located on the same horizontal plane.

[0040] Among them, the handheld pneumatic walking flame gun 3 is provided with a flame control button 37 connected to the flame controller and a drive motor rotation button 38. By pressing the flame control button 37, the size of the flame of the flamethrower 33 can be adjusted. By pressing the drive motor rotation button 38, the drive motor 31 drives the transmission rod 36 to rotate, thereby realizing the rotation of the drive wheel 34, realizing electric power assistance, and improving the laying efficiency of the waterproof membrane.

[0041] Reference Figure 1 A reinforcing rod 39 is fixedly connected to the handheld pneumatic walking flame gun 3. The setting of the reinforcing rod 39 increases the structural strength of the handheld pneumatic walking flame gun 3, thereby extending the service life of the semi-automatic flame edge banding machine. Furthermore, a plurality of screws 8 are threadedly connected to the side wall of the bracket 1, and an arc plate 81 is fixedly connected to one end of the screw 8 close to the gas tank 2. The screw 8 is rotated to drive the arc plate 81 to approach or move away from the gas tank 2. When the screw 8 is tightened, the arc plate 81 fits and presses against the outer wall of the gas tank 2. The mutual cooperation of the plurality of screws 8 realizes the fixation of the gas tank 2 on the bracket 1, and improves the stability of the coil laying work. At the same time, the simple setting of the screw 8 and the arc plate 81 enables the bracket 1 to fix gas tanks 2 of different sizes, thereby improving the practicality of the entire device.

[0042] Reference Figure 2 One end of the handheld pneumatic walking flame gun 3 is fixedly connected to a base 5, on which a sliding rod 51 is provided, and the extension direction of the sliding rod 51 is parallel to the rotation axis of the driving wheel 34. One end of the flame spray nozzle 33 is fixedly connected to a sliding block 52, which is rotatably sleeved on the sliding rod 51 and has an interference fit with the sliding rod 51, and the flame outlet of the flame spray nozzle 33 is consistent with one of the extension directions of the sliding rod 51 along its length.

[0043] When laying waterproofing coiled materials, the sliding block 52 is pushed to make it close to the edge of the coiled material overlap, and then the flame spraying nozzle 33 is rotated to be inserted in the middle of the coiled material overlap to spray fire. After the coiled material melts, the driving wheel 34 presses it. When it is not necessary to spray fire, the sliding block 52 is directly pushed away from the coiled material overlap, so that the flame spraying nozzle 33 can be moved out from the coiled material overlap, which improves practicality.

[0044] Reference Figure 2 The supporting part 4 includes a rotating ring 41, a connecting rod 42 and a limiting rod 43. The rotating ring 41 is rotatably connected to the side wall of the flame-spraying nozzle 33. One end of the connecting rod 42 is hingedly connected to the rotating ring 41, and the other end is hingedly connected to the limiting rod 43. The flame-spraying nozzle 33 is provided with a slide groove 6, and the two inner side walls of the slide groove 6 are provided with limiting grooves 61. The limiting rod 43 is slidably arranged between the two limiting grooves 61, and an elastic clamping member 7 for fixing the limiting rod 43 is arranged inside the limiting rod 43.

[0045] When laying the waterproofing membrane, the rotating ring 41 is rotated to tilt it to a certain angle, so as to facilitate lifting the overlapping edge of the waterproofing membrane. By adjusting the elastic clamping member 7, the connecting rod 42 is in a fixed state, thereby ensuring the stability of the tilting of the rotating ring 41, and facilitating the continuous laying of the waterproofing membrane. After the laying work is completed, the elastic clamping member 7 is adjusted to make the connecting rod 42 overlap the top of the flame nozzle 33. Due to the supporting effect of the connecting rod 42, the extending direction of the rotating ring 41 is consistent with that of the flame nozzle 33, which is convenient for storage and arrangement, and improves practicality.

[0046] Reference Figure 3 The elastic clamping member 7 includes a spring 71 arranged in the limiting rod 43 and a clamping ball 72 fixedly connected to both ends of the spring 71. The bottoms of the two limiting grooves 61 are respectively provided with a plurality of mutually aligned clamping grooves 62, and the clamping ball 72 is elastically embedded in the clamping groove 62.

[0047] The limit rod 43 is pushed to slide in the limit groove 61. The limit rod 43 slides to drive the connecting rod 42, and the connecting rod 42 drives the rotating ring 41 to rotate within a certain angle range, thereby realizing the adjustment of the lifting angle of the rotating ring 41. When the limit rod 43 slides, the spring 71 inside it is compressed and tightened to accumulate elastic force. When it needs to be fixed, the limit rod 43 is slid to the position of the clamping groove 62. The spring 71 naturally recovers to provide power to drive the clamping ball 72 to be clamped in the clamping groove 62, thereby realizing the fixation of the limit rod 43 and the connecting rod 42, which is convenient for the rotating ring 41 to stably lift the overlapping edge of the coil. When the rotating ring 41 needs to be retracted, it is only necessary to push the limit rod 43 horizontally. The spring 71 is compressed and tightened, and the clamping ball 72 shrinks in the limit rod 43, which is convenient for moving the limit rod 43 and improves practicality.

[0048] Reference Figure 4 The flame outlet of the flame nozzle 33 is flattened, and the flattened flame outlet makes the flame uniform and more suitable for the overlapping edge of the coiled material. After the coiled material is heated evenly, the bonding strength is improved, and the laying effect of the waterproof coiled material is enhanced.

[0049] The implementation principle of this embodiment is: during construction, the supporting part 4 is inserted under the waterproof membrane to support the overlapping edge, the power module 32 is turned on to power the drive motor 31 and the flame controller, and the flame nozzle 33 sprays flame to spray the overlapping seam of the waterproof membrane. The operator holds the handheld pneumatic walking flame gun 3 with one hand and pushes the bracket 1 with the other hand. The driving motor 31 assists the driving wheel 34 to rotate. The rotation of the driving wheel 34 presses the overlapping seam of the waterproof membrane. The advancement speed of the flat membrane hot-melt edge sealing machine is controlled according to the melting speed of the flame-sprayed membrane to ensure the quality of the hot-melt edge sealing of the membrane.

[0050] During the whole process, one person can independently operate to lay the modified asphalt waterproof membrane. The driving wheel 34 is driven by electric power to rotate, so as to realize the smearing and pressing of the overlapping edges of the modified asphalt waterproof membrane, which saves time and labor, is simple to operate, and improves the efficiency and safety of the construction.
