Description

Technical Field

[0001] This utility model belongs to the technical field of hot melt butt welding machines, and relates to a hot melt butt welding machine with a reinforced heat dissipation structure. Background Technology

[0002] The main drawback of existing hot melt butt welding machines in terms of heat dissipation is that the heat generated during the welding process cannot be dissipated in a timely and effective manner, leading to excessively high welding temperatures and affecting welding quality and equipment lifespan. These shortcomings are primarily due to insufficient consideration of the heat dissipation system in the welding machine design, or limitations in heat dissipation materials and technologies. For example, the size, shape, and material of the radiator may be insufficient to handle the heat generated by prolonged or high-intensity welding operations; the power of cooling devices such as fans may be insufficient or their layout unreasonable, failing to create effective airflow; and inadequate internal thermal insulation measures cause heat to accumulate inside the welding machine.

[0003] Conventional solutions include increasing the size and number of heat sinks, using more efficient fans, and improving internal thermal isolation design. However, these methods have drawbacks: they may increase the size and weight of the welding machine, making it more inconvenient to operate; adding heat sinks and fans may increase costs and energy consumption; and improving thermal isolation design may complicate the welding machine structure, increasing manufacturing difficulty and maintenance costs. Therefore, there is an urgent need for a thermofusion butt welding machine with a reinforced heat dissipation structure to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hot melt butt welding machine with a reinforced heat dissipation structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a hot melt butt welding machine with a reinforced heat dissipation structure, including: a welding pipe and a cooling fan. The welding pipe is provided with two sets. A set of outer clamping rings for clamping and fixing the welding pipe is provided on the outer side of the middle position of the welding pipe on the left and right sides. A set of cooling cover is provided on the right side of the outer clamping ring on the left side for cooling the welding pipe on the left side.

[0006] The cooling cover includes an outer shell and a water exchange pipe. The outer shell has a set of inner support shells at its left and right ends for fitting and positioning with its inner side. Several sets of inner heat-conducting tiles are provided on the outer side of the middle position of the two sets of inner support shells for providing water cooling to the outside of the welded pipe. The inner heat-conducting tiles are made of a ceramic material. Each set of inner heat-conducting tiles has a set of cooling water pipes for circulating and guiding the cooling water inside.

[0007] In a preferred embodiment, the right-side cross-section of the inner heat-conducting tile is a circular structure. The inner heat-conducting tile contains a cooling chamber for cooling the welded pipes, and the lower end of the inner heat-conducting tile contains a water storage chamber for pre-storing cooling water. When the operator places two sets of welded pipes to be welded inside several sets of outer retaining rings, the welded pipes are moved inwards synchronously, maintaining the contact position of the two sets of welded pipes at the middle of the inner side of the docking cover. The operator then opens the docking cover and performs welding operations on the two sets of welded pipes. During welding, the cooling water in the circulating water tank is pumped into the exchange water pipe by a guide water pump, and then guided into the water storage chamber through the exchange water pipe. Subsequently, the cooling water circulates around the inner heat-conducting tile through several sets of cooling water pipes, continuously cooling the inner heat-conducting tile. Simultaneously, the inner heat-conducting tile provides efficient circumferential cooling to the welded pipes inside, reducing heat transfer.

[0008] In a preferred embodiment, the lower left end of the water storage chamber is provided with two sets of exchange water pipes for circulating and extracting the internal cooling water, and the inner side of the outer retaining ring is provided with an inner fitting ring for protecting the outer side of the welded pipe from deformation and paint peeling caused by extrusion.

[0009] In a preferred embodiment, the fitting ring is made of a metal material, and the outer retaining ring is divided into an upper part and a lower part. The upper part is a movable structure, and the lower end of the upper part is provided with a set of lower parts for supporting it. A set of hinge pins for supporting the flipping movement of the upper part is provided at the left connection between the upper part and the lower part.

[0010] In a preferred embodiment, a set of fixing seats is provided at the upper and lower right contact positions to increase the contact surface between the upper and lower parts and fix them. Each of the two sets of fixing seats is provided with an inner hole. A cooling cover is provided on the left side of the outer retaining ring on the right side for cooling the welded pipe on the right side.

[0011] In a preferred embodiment, the first cooling cover and the second cooling cover are of the same specifications. A set of docking covers is provided between the first cooling cover and the second cooling cover for protecting the welding joints of the two sets of welded pipes. The docking covers are detachable structures, and two sets of external retaining rings are provided on the outer sides of the welded pipes on the left and right sides respectively.

[0012] As a preferred embodiment, several sets of outer retaining rings are provided with a set of outer support frames on the front and rear sides for supporting them. The outer support frames are formed into a rectangular structure, and a set of cooling cavities are provided inside the outer support frames. The cooling cavities are provided with a circulating water tank and a guide water pump. The interior of the circulating water tank is connected to the interior of the exchange water pipe through the guide water pump, which provides pumping power to the cooling water inside the circulating water tank.

[0013] As a preferred embodiment, the external support frame is provided with a set of cooling fans on the front and rear sides for exhausting the hot air inside the cooling cavity. Each set of cooling fans is provided with a set of external louvers for guiding the exhaust air. When the cooling cavity generates heat due to the continuous and long-term circulation of cooling water, the staff can use the two sets of cooling fans to exhaust the hot air inside the cooling cavity and change the exhaust path of the hot air through the external louvers to prevent direct exhaust to the bodies of surrounding staff.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the workers place the two sets of welding pipes to be welded inside several sets of outer retaining rings, they move the welding pipes to be welded inwards synchronously, keeping the contact position of the two sets of welding pipes in the middle of the inner side of the docking cover. Then, the workers open the docking cover and perform welding operations on the two sets of welding pipes. During the welding process, the cooling water inside the circulating water tank is pumped into the exchange water pipe by the guide water pump, and then the cooling water is introduced into the storage chamber through the exchange water pipe. Subsequently, it is surrounded by several sets of cooling water pipes and continuously cooled inside the inner heat-conducting tile. At the same time, the inner heat-conducting tile provides efficient surrounding cooling for the welding pipe inside, so as to reduce heat transfer and enhance the heat dissipation effect. When the cooling cavity generates heat due to the continuous long-term circulation supply of cooling water, the workers can use two sets of cooling fans to exhaust the hot air inside the cooling cavity, and change the exhaust path of the hot air through the outer louver door to prevent direct exhaust to the bodies of the surrounding workers.
