Description

Technical Field

[0001] This application relates to the technical field of coil welding machines, and specifically discloses a forward-type waterproof coil welding machine. Background Art

[0002] During the laying process of waterproof coils, it is necessary to weld the gaps between adjacent waterproof coils to improve the overall waterproof performance. A waterproof coil welding machine is a device that can automatically weld the gaps between adjacent waterproof coils, replacing the manual welding process, and has advantages such as high welding efficiency and low labor intensity.

[0003] The principle of a waterproof coil welding machine is based on hot air welding technology. The materials at the joint of the coils are heated to a molten state by high-temperature hot air or a hot wedge structure. After melting, the coils are tightly combined under the extrusion of the pressure wheel to form a uniform weld seam. The molten material solidifies after natural or assisted cooling to form a high-strength seamless connection.

[0004] However, during the use of current waterproof coil welding machines, there are the following drawbacks: First, most existing waterproof coil welding machines use a backward movement method to maintain the stability of the welding position, which is not convenient for workers to directly observe whether there are defects in the weld seam after welding. Second, existing waterproof coil welding machines generally have a single-pressure wheel structure. Each time welding is performed, the gap edges of the waterproof coils to be welded must be strictly aligned. Otherwise, there will be problems with poor welding quality, resulting in higher requirements for construction workers and greater labor intensity during the welding process. Third, existing waterproof coil welding machines generally lack a structure for cooling the pressure wheel and the welded waterproof coils. As a result, the temperature of the pressure wheel during welding and the weld seam after welding is relatively high, which is likely to cause burns to workers. At the same time, it also increases the danger of the working environment during the construction of waterproof coils and is prone to causing safety accidents. In view of this, the present invention provides a forward-type waterproof coil welding machine to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that traditional waterproof coil welding machines use a single-pressure wheel structure, and during the welding process, the gap edges of the waterproof coils to be welded must be strictly aligned, resulting in greater labor intensity for construction workers.

[0006] To achieve the above purpose, the basic solution of the present invention provides a forward-type waterproof coil welding machine, including: A traveling mechanism, including a vehicle frame, wheels symmetrically and rotatably installed at the bottom of the vehicle frame, and a handrail provided on one side of the vehicle frame; A hot melting mechanism, including a mounting frame provided on the vehicle frame, a wind cylinder provided on the mounting frame, a blower for supplying air into the wind cylinder, a heater for heating the air in the wind cylinder, and a nozzle for guiding the heated air to the welding area of the waterproof coil; The pressing mechanism includes a front pressing wheel, a rear pressing wheel arranged on the vehicle frame in sequence along the traveling direction of the traveling mechanism, and a driving assembly arranged on the vehicle frame and driving the rear pressing wheel to rotate.

[0007] The principle and effect of this basic solution are as follows: Compared with the prior art, the present invention uses both ends of the front pressing wheel and the rear pressing wheel to press tightly, preventing the situation of curled edges at the gaps between adjacent two coiled materials, being able to reduce the requirement for whether the gap edges of the waterproof coiled materials to be welded are suitable, effectively reducing the requirements for construction workers and the labor intensity of construction workers. And on this basis, due to the reduction of the requirement for whether the gap edges of the waterproof coiled materials are suitable, during the welding process of the waterproof coiled materials, the waterproof coiled material welding machine can adopt a forward movement. Not only is it more convenient during the operation process, but also it is convenient to directly observe whether there are welding defects in the gaps between adjacent two waterproof coiled materials. Obviously, the present invention has stronger applicability, higher error tolerance, and more convenient construction, effectively solving the problem that the traditional waterproof coiled material welding machine uses a single pressing wheel structure and requires strict control of the gap edges of the waterproof coiled materials to be welded during the welding process, resulting in a relatively large labor intensity for construction workers.

[0008] Furthermore, it further includes a temperature reduction mechanism. The temperature reduction mechanism includes a water tank arranged on the vehicle frame and sprayers respectively arranged above the front pressing wheel and the rear pressing wheel. Water pipes are provided between the sprayers and the water tank, and water pumps are arranged on the water pipes. The temperature reduction mechanism cools the front pressing wheel and the rear pressing wheel in real time, making the front pressing wheel and the rear pressing wheel keep moist, avoiding the waterproof coiled materials from being adhered to the front pressing wheel and the rear pressing wheel due to heat, resulting in inconvenient subsequent cleaning problems. At the same time, it can effectively improve the service life of the front pressing wheel and the rear pressing wheel. At the same time, it also reduces the temperature of the welded waterproof coiled materials, accelerates the cooling and forming of the waterproof coiled materials, avoids the weld seam temperature being too high and scalding the staff, and improves the safety during the construction process of the waterproof coiled materials.

[0009] Furthermore, the pressing mechanism further includes a telescopic frame arranged on the vehicle frame and capable of horizontal expansion and contraction. The front pressing wheel is rotatably connected to the side of the telescopic frame far from the vehicle frame. The telescopic frame is convenient for adjusting the position of the front pressing wheel, so that the distance between the front pressing wheel and the rear pressing wheel can be flexibly adjusted according to the on-site construction needs.

[0010] Furthermore, the telescopic frame includes sleeves symmetrically connected to the vehicle frame, sliding rods respectively slidably connected to the sleeves, and a mounting seat arranged at the end of the sliding rod and for rotatably mounting the front pressing wheel. The sleeves and the sliding rods cooperate with each other, which is convenient for adjusting the position of the front pressing wheel.

[0011] Furthermore, the width of the front pressing wheel is smaller than the width of the rear pressing wheel. So as to eliminate the curled edge when there is a curled edge situation at the gap between adjacent two waterproof coiled materials after the front pressing wheel presses tightly.

[0012] Furthermore, the lowest level of the wheels is higher than the lowest level of the front and rear pressure wheels. This allows the front and rear pressure wheels to be in contact with the waterproofing coiled material during welding, while the wheels do not. After welding is completed, the front and rear pressure wheels can be manually adjusted to tilt upwards, using the wheels as fulcrums and the handrails as support points, so that the wheels are in contact with the ground, while the front and rear pressure wheels do not.

[0013] Furthermore, the device includes a recovery mechanism comprising a roller rotatably connected to a frame, a plurality of water-absorbing strips disposed at the circumference of the roller, and a recovery bin disposed on the frame. The recovery bin has an opening at the top, and the distance between the edge of the opening and the roller, as well as the distance between the roller and the waterproofing membrane, is less than the thickness of the water-absorbing strips. As the roller rotates, the water-absorbing strips absorb water and oil stains from the surface of the waterproofing membrane. The water-absorbing strips are squeezed by the opening edge of the recovery bin during rotation, so that the water and oil stains absorbed by the water-absorbing strips are squeezed into the recovery bin, thereby recovering the water sprayed by the cooling mechanism and the oil stains generated during welding.

[0014] Furthermore, the recycling mechanism also includes a scraper mounted on the frame and scraping along the surface of the waterproof roll, and the roller is rotatably connected to the side of the scraper close to the pressure wheel, so as to more comprehensively scrape off the accumulated water and oil stains on the waterproof roll.

[0015] Furthermore, the recovery mechanism also includes an adjustment assembly for adjusting the vertical height of the scraper. The adjustment assembly includes a fixed plate mounted on the frame, a screw threadedly connected to the fixed plate, and a guide rod slidably connected to the fixed plate. The guide rod is fixedly connected to the scraper, and the screw is rotatably connected to the scraper. By rotating the screw, the scraper is raised and lowered by the screw and the fixed plate. The guide rod limits and guides the scraper during the lifting process to adjust the height of the scraper.

[0016] Furthermore, a partition is provided inside the water tank, which divides the water tank into a water storage chamber and a recovery chamber. A recovery pipe is provided between the bottom of the recovery chamber and the recovery chamber to facilitate the centralized recovery of the water sprayed by the cooling mechanism and the oil stains during the welding process.
