Description

Technical Field

[0001] This application relates to the field of building waterproofing construction equipment technology, and more specifically, to a uniform heating device for self-adhesive asphalt rolls used in building waterproofing construction. Background Technology

[0002] Self-adhesive bitumen membrane is a type of waterproofing material used in construction. It consists of multiple layers, with a high-quality polypropylene or polyester film as the core layer and adhesive bitumen layers on both sides. It exhibits good weather resistance, corrosion resistance, and chemical resistance. Under certain temperatures, it can be applied directly to the substrate surface without the need for heating with a torch; simply removing the protective film is sufficient. However, self-adhesive bitumen membrane hardens at low temperatures, making it difficult to adhere to the substrate. Therefore, it requires pre-treatment with heat before application. Uneven heating during this process can result in inconsistent bitumen layer hardness, hindering adhesion to the substrate and compromising waterproofing effectiveness.

[0003] The prior art publication CN218176672U provides a self-adhesive asphalt roll uniform heating device. This device reduces heat consumption and improves heating uniformity by using multiple heating guns. At the same time, a pressing groove for compacting the roll is set on the heating box, and a counterweight is placed in the pressing groove to ensure a good bonding effect.

[0004] However, the method of compacting the roll material by placing counterweights on the groove suffers from uneven stress distribution. Furthermore, this method is relatively simple and singular, resulting in poor compaction effectiveness and consequently, limited practicality.

[0005] In view of this, we propose a uniform heating device for self-adhesive asphalt rolls used in building waterproofing construction. Summary of the Invention

[0006] To overcome a series of defects in existing technologies, the purpose of this patent is to provide a uniform heating device for self-adhesive asphalt rolls used in building waterproofing construction, comprising: a movable base 1, a roll roll pressing and exhaust mechanism 3, a gas cylinder 4, a heating mechanism 5, and a base treatment mechanism 6. A transmission mechanism 2 is rotatably connected to the movable base 1; two roll roll pressing and exhaust mechanisms 3 are provided and fixedly connected to the movable base 1; the gas cylinder 4 is placed on the movable base 1; the heating mechanism 5 is rotatably connected to the movable base 1; and the base treatment mechanism 6 is fixedly connected to the movable base 1.

[0007] In this process, after the asphalt roll is heated, the transmission mechanism 2 drives the roll roll pressing and exhaust mechanism 3 to continuously press and exhaust air from the middle of the roll to both sides, thereby enhancing the adhesion between the roll and the base layer.

[0008] Furthermore, a placement rack 101 is fixedly connected to the rear side of the top surface of the movable seat 1, and roll material placement seats 102 are fixedly connected to both ends of the front side of the top surface of the movable seat 1. A roll material guide groove 103 is opened in the middle of the movable seat 1.

[0009] An adjusting rod 104 is threadedly connected to the movable seat 1. The lower end of the adjusting rod 104 extends to the lower side of the movable seat 1 and is rotatably connected to a pressure plate 105.

[0010] In the above technical solution, one end of the roll material is pulled out and passed through the roll material guide groove 103, and then the adjusting rod 104 is rotated so that the pressure plate 105 presses onto the roll material.

[0011] Furthermore, the transmission mechanism 2 includes two belts 201, and pulleys 202 are frictionally driven on the inner walls of both ends of the belts 201. The pulleys 202 near the outer side are rotatably connected to the inner wall of the movable seat 1, and the two pulleys 202 near the middle are fixedly connected by a pin. A fixing frame 203 is rotatably connected to the outer wall of the pin, and the fixing frame 203 is fixedly connected to the movable seat 1.

[0012] In the above technical solution, the rotation of the pin shaft can drive the two pulleys 202 to rotate.

[0013] Furthermore, a driven wheel 204 is fixedly sleeved on the pin shaft, and a driving wheel 205 is engaged on one side of the driven wheel 204. A motor 206 is fixedly connected to the movable seat 1, and the output end of the motor 206 is coaxially fixedly connected to the driving wheel 205.

[0014] Furthermore, the roll material roll forming and exhaust mechanism 3 includes a guide rod 301 that is fixedly connected to the movable seat 1. A movable block 302 is slidably fitted on the guide rod 301. A movable frame 303 is slidably fitted through the movable block 302. A connecting rod 304 is rotatably connected to the lower side of the movable frame 303. The other end of the connecting rod 304 is fixedly connected to one of the belts 201.

[0015] In the above technical solution, the belt 201 drives the roll material pressing and exhaust mechanism 3 to move.

[0016] Furthermore, a connecting disc is fixedly connected to the lower end of the movable frame 303, and a limiting frame with an inverted U-shaped structure is fixedly connected to the side of the connecting disc. Two vertical strip holes are symmetrically opened on the limiting frame, and sliding blocks are slidably limited in each of the vertical strip holes. A roller shaft 307 is rotatably connected between the two sliding blocks. A connecting column is connected to the top of each sliding block. The upper ends of the two connecting columns slide upward through the limiting frame and extend to its upper side and are fixedly connected to the same limiting plate 305. Multiple springs 306 are fixedly connected between the limiting plate 305 and the limiting frame.

[0017] In the above technical solution, under the action of spring 306, the limiting plate 305 moves downward, so that the roller 307 can press on the roll material.

[0018] Furthermore, the heating mechanism 5 includes a flame head 501, which is rotatably connected to the movable base 1. One end of the flame head 501 is connected to the gas cylinder 4 through a pipe. A gear 502 is fixedly sleeved on the flame head 501, and a rack 503 is meshed with the gear 502. The rack 503 is slidably engaged with the movable base 1.

[0019] Furthermore, a connecting rod 504 is rotatably connected to the other end of the rack 503; a bent rod 207 is fixedly connected to the shaft of one of the pulleys 202, and the outer wall of the bent rod 207 is rotatably connected to the outer wall of the connecting rod 504.

[0020] In the above technical solution, one of the pulleys 202 drives the bent rod 207 to rotate, and then drives the rack 503 to reciprocate through the connecting rod 504, thereby driving the flame head 501 connected to the gear 502 to reciprocate.

[0021] Furthermore, the base treatment mechanism 6 includes a paint bucket 601 fixedly mounted on the movable base 1, and a spray rod 602 connected to the other end of the paint bucket 601 via a pump body. The spray rod 602 is rotatably connected to one end of the movable base 1. A push-pull mechanism 603 is rotatably connected to the spray rod 602, and the other end of the push-pull mechanism 603 is rotatably connected to one end of the flame head 501.

[0022] In the above technical solution, the flame head 501 drives the spray bar 602 to swing back and forth through the push-pull mechanism 603. At this time, the pump body will draw out the paint in the paint bucket 601 and spray it onto the surface of the base layer.

[0023] The purpose of this application is also to provide a method for using a uniform heating device for self-adhesive bitumen rolls used in building waterproofing construction, including the following steps:

[0024] Place the roll material on the two roll material placement seats 102, pull one end of the roll material out and pass it through the roll material guide groove 103, and rotate the adjusting rod 104 to make the pressure plate 105 press the roll material.

[0025] Open the gas cylinder valve 4, ignite it through the burner head 501, and then spray the flame onto the roll material to heat and melt the asphalt;

[0026] At the same time, starting the motor 206 can drive the bent rod 207 to rotate through one of the pulleys 202, thereby driving the rack 503 to move back and forth through the connecting rod 504, thereby driving the flame head 501 connected to the gear 502 to swing back and forth, thus achieving uniform heating of the roll material.

[0027] At the same time, the oscillating flame head 501 drives the spray bar 602 to oscillate back and forth through the push-pull mechanism 603. Under the action of the pump, the paint in the paint bucket 601 is evenly sprayed onto the surface of the base layer.

[0028] At the same time, the belt 201 drives the roll material roller pressing and exhaust mechanism 3 to move. When the belt 201 drives the roll material roller pressing and exhaust mechanism 3 to move downward, the roller 307 will press on the roll material so that the roll material can stick to the surface of the base layer.

[0029] Compared with the prior art, this application has at least the following technical effects or advantages:

[0030] In this application, driven by the transmission mechanism, the rollers squeeze the roll material from the middle to both sides, allowing the air between the roll material and the base surface to be fully discharged, thus improving the laying efficiency of the roll material. At the same time, the transmission mechanism drives the nozzle to oscillate back and forth, reducing the number of nozzles and lowering the production cost of the device. In addition, a base treatment mechanism is set up, and the spray bar sprays the base treatment agent onto the base surface of the roll material to be laid, enhancing the adhesion between the roll material and the base surface, further improving the waterproof effect of the roll material, and improving the practicality of the device.

[0055] The implementation principle of this application embodiment is as follows: When laying asphalt rolls, the rolls are first placed on the roll placement seat 102, then one end of the roll is pulled out and passed through the roll guide groove 103, and then the adjusting rod 104 is rotated so that the pressure plate 105 presses on the rolls.

[0056] Then open the gas cylinder valve 4, ignite it through the burner head 501, and then spray the flame onto the roll material to heat and melt the asphalt;

[0057] At this time, the starter motor 206 can drive the two pulleys 202 connected to the driven wheel 204 to rotate through the drive wheel 205. At this time, one of the pulleys 202 will drive the bent rod 207 to rotate, and then drive the rack 503 to move back and forth through the connecting rod 504, thereby driving the flame head 501 connected to the gear 502 to swing back and forth, so that the flame head 501 can heat the roll material evenly.

[0058] At the same time, the oscillating flame head 501 will drive the spray bar 602 to oscillate back and forth through the push-pull mechanism 603. At this time, the pump body will draw out the paint in the paint bucket 601 and spray it onto the base surface. Then, the flames sprayed out by the flame head 501 heat the roll material, and the high temperature generated will also accelerate the drying of the paint.

[0059] At the same time, the belt 201 drives the roll material roller pressing and degassing mechanism 3 to move. When the belt 201 drives the roll material roller pressing and degassing mechanism 3 to move downward, the roller 307 will press on the roll material so that the roll material can stick to the base surface, thereby rolling and degassing the roll material from the middle to both sides, so that the roll material can stick to the base surface.

[0060] In summary, in this embodiment, driven by the transmission mechanism 2, the roller 307 will squeeze from the middle of the roll material to both sides, thereby fully expelling the air between the roll material and the base surface, making the squeezing force uniform, and thus improving the laying efficiency of the roll material.
