Description

Technical Field

[0001] This utility model relates to welding machines, and more particularly to a welding machine with a dustproof casing. Background Technology

[0002] Electric welding machines utilize the high-temperature electric arc generated when positive and negative electrodes are momentarily short-circuited to melt the welding rod and the material being welded, thus bonding the objects together. To achieve heat dissipation during operation, an exhaust fan is typically installed on the end face of the welding machine casing, with an air inlet on its side. Activating the exhaust fan forces air out of the casing, creating a negative pressure environment. External air then flows into the casing through the air inlet, cooling the equipment inside, before finally being exhausted back out through the exhaust fan.

[0003] Existing welding machine chassis allow airflow through air inlets on the surface, but these inlets lack dust protection, allowing external dust to enter the chassis. This is especially problematic during welding operations when there is a significant amount of dust in the air. This dust entering the chassis can affect the operation of internal equipment and, in severe cases, pose safety hazards. Furthermore, while the chassis uses fans for cooling, when the welding machine is not in use, dust often adheres to the fans due to airflow, and some dust can even enter the chassis through fan gaps, affecting the machine's continued operation. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a welding machine with a dustproof enclosure to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A welding machine with a dustproof enclosure includes a housing and a cover installed on the outside of the housing. The housing is sealed by the cover, and the cover is connected to the housing by bolts. Several air inlets (I) communicating with the interior of the housing are provided on both sides of the cover. Several air inlets (II) are provided on one side of the housing. Each air inlet (I) and air inlet (II) is covered with a dust cover with its opening facing downwards. Filters are installed inside both the housing and the cover, each filter corresponding to one or more air inlets. Removal components for removing the filters are provided inside both the cover and the housing. Two air outlets are provided on the other side of the housing, and cooling fans are installed on both outlets. A sealing component for sealing the air outlets is provided on the outside of the housing.

[0007] Preferably, the disassembly assembly includes mounting strips and grooves formed on the mounting strips. The mounting strips are symmetrically arranged on the inner walls of the housing and the cover. Each of the first and second air inlets is located between two mounting strips. The grooves are formed on the side of the mounting strips near the housing and the cover. The two grooves are arranged opposite each other. The grooves are through-hole structures on one side. The filter screen is inserted into the groove through one through-hole. The filter screen is installed through the grooves on the two mounting strips. A sealing element is also provided on the side of the filter screen near the first and second air inlets. The filter screen is sealed to the housing and the cover through the sealing element.

[0008] Preferably, the sealing element is made of rubber and is rectangular in shape. The upper and lower ends of the sealing element are slidably disposed in the groove through the filter screen.

[0009] Preferably, the sealing assembly includes two sealing rings and two sealing plugs. The two sealing rings are installed on the outer wall of the housing, and the two sealing rings are respectively opposite to the two air outlets. The two sealing plugs are respectively installed on the side of the sealing ring away from the air outlet, and the sealing rings and sealing plugs are engaged by a snap-fit.

[0010] Preferably, a rubber plug is fixedly installed on the side of the sealing plug near the sealing ring, and the sealing plug achieves a snap-fit ​​engagement with the sealing ring through the rubber plug.

[0011] Preferably, the top of the lid is equipped with two handles, and the bottom of the casing is equipped with multiple casters.

[0012] Beneficial effects: When the welding machine is in use, the two cooling fans will turn on, exhausting the air inside the welding machine and creating a negative pressure inside. The welding machine will then draw in outside air through air inlets one and two to cool the equipment inside the casing. When the outside air enters the welding machine through air inlets one and two, it will first pass through a dust cover for preliminary filtration. The air enters the dust cover from the bottom, which reduces the entry of dust. The air entering through air inlets one and two will also pass through a filter screen for secondary filtration, further removing impurities and preventing dust and particulate matter from entering the welding machine, ensuring the cleanliness of the inside of the welding machine. The filter screen is detachable and can be cleaned regularly to ensure the filtration effect.

[0013] When the welding machine is not in use, a sealing component can be installed on the outside of the air outlet to prevent dust from entering the machine through the gap between the air outlet and the cooling fan. The sealing component seals the air outlet, preventing dust from entering the welding machine. When the welding machine is in use, the sealing component can be opened manually, making the operation convenient. Attached Figure Description

[0021] See Figures 1 to 6 As shown, a welding machine with a dustproof enclosure includes a housing 1 and a cover 2 installed on the outside of the housing 1. The housing 1 is sealed by the cover 2. Several air inlets 3 communicating with the inside of the housing 1 are opened on both sides of the cover 2. Several air inlets 4 are opened on one side of the housing 1. Two air outlets 8 are opened on the other side of the housing 1. Cooling fans 9 are installed on both air outlets 8. When the welding machine is in use, the two cooling fans 9 will be turned on in order to dissipate heat from the welding machine. The cooling fans 9 will exhaust the air inside the welding machine, so that a negative pressure is formed inside the welding machine. The welding machine will draw outside air into the housing 1 through the air inlets 3 and air inlets 4, so as to dissipate heat from the equipment inside the enclosure.

[0022] Dust covers 5 are installed on the outside of each air inlet 3 and air inlet 4. The opening of the dust cover 5 faces downward. When the outside air enters the welding machine through air inlet 3 and air inlet 4, it will first pass through the dust cover 5 for preliminary filtration. The air inlet of the dust cover 5 is located at the bottom, and the air enters the dust cover 5 from the bottom. The dust cover 5 is installed on the outside of the air inlet 3 and air inlet 4 of the welding machine. It can effectively block larger dust particles and impurities, reducing the possibility of dust entering the welding machine. The opening of the dust cover 5 is designed to face downward. This structure can use the principle of gravity to make the dust fall naturally instead of adhering to the surface of the dust cover 5, reducing the possibility of dust accumulation. The dust cover 5 not only filters dust, but also protects the air inlet from external impact or damage.

[0023] Both the housing 1 and the cover 2 are equipped with filters 6. Each filter 6 corresponds to an air inlet 3 and an air inlet 4, respectively. Both the cover 2 and the housing 1 are equipped with a disassembly assembly 7 for removing the filters 6. The air entering the air inlet 3 and the air inlet 4 will be filtered a second time through the filters 6 to further remove impurities from the air and prevent dust and particulate matter from entering the welding machine, thus ensuring the cleanliness of the welding machine. The filters 6 are detachable through the disassembly assembly 7, which allows for regular cleaning of the filters 6.

[0024] The cover 2 and the housing 1 are connected by bolts. When the filter screen 6 needs to be disassembled and cleaned, the cover 2 and the housing 1 can be separated by removing the bolts. After the cover 2 is removed from the housing 1, the operator can remove the filter screen 6 through the disassembly component 7 set on the cover 2. In order to connect with the cover 2, the side wall of the housing 1 will have an extension edge that connects to the cover 2. Therefore, when designing the air inlet 4 and the disassembly component 7 on the housing 1, priority should be given to the positional relationship between the air inlet 4 and the disassembly component 7 and the side wall of the housing 1 to ensure that there is enough room for the filter screen 6 to move when it is disassembled.

[0025] The disassembly assembly 7 includes mounting strips 71 and sliding grooves 72 formed on the mounting strips 71. The mounting strips 71 are symmetrically arranged on the inner walls of the housing 1 and the cover 2. Each air inlet 3 and air inlet 4 is located between the two mounting strips 71. The sliding grooves 72 are formed on the side of the mounting strips 71 near the housing 1 and the cover 2. The two sliding grooves 72 are arranged opposite each other and have a one-way through structure. The filter screen 6 is inserted into the sliding groove 72 through one side. The filter screen 6 is installed through the sliding grooves 72 on the two mounting strips 71. When it is necessary to remove the filter screen 6, the filter screen 6 can be slid and slid towards the opening of the sliding groove 72. The filter screen 6 will gradually detach from the two mounting strips 71 until the filter screen 6 is completely removed from the two mounting strips 71, thereby realizing the removal and cleaning of the installed filter screen 6.

[0026] A sealing element 73 is also provided on the side of the filter screen 6 near the air inlet 1 3 and the air inlet 2 4. The filter screen 6 achieves a sealed installation with the housing 1 and the cover 2 through the sealing element 73. In order to ensure that the filter screen 6 can fit tightly with the housing 1 and prevent dust from flowing out from the gap between the filter screen 6 and the housing 1, the sealing element 73 is installed on the end face of the filter screen 6. During the installation process, the sealing element 73 will fit tightly against the inner wall of the housing 1.

[0027] The seal 73 is made of rubber and is rectangular. The upper and lower ends of the seal 73 are slidably mounted in the groove 72 through the filter screen 6. When the filter screen 6 slides into the groove 72, it will drive the upper and lower ends of the seal 73 to slide into the groove 72. After entering the groove 72, the seal 73 will be squeezed between the groove 72 and the housing 1, thus ensuring the sealing installation between the filter screen 6 and the housing 1. When the filter screen 6 drives the seal 73 to the designated position, each air inlet 1 3 and air inlet 2 4 will be located in the middle of the seal 73. This will block the air entering the housing 1 from the air inlet 1 3 and air inlet 2 4, and the air can only enter the housing 1 through the filter screen 6, thereby achieving air filtration.

[0028] The outer side of the housing 1 is provided with a sealing component 10 for sealing the air outlet 8. When the welding machine is not in use, in order to prevent dust from entering the inside of the welding machine through the gap between the air outlet 8 and the cooling fan 9, the sealing component 10 can be installed on the outside of the air outlet 8. The sealing component 10 seals the air outlet 8 and prevents dust from entering the inside of the welding machine.

[0029] The sealing assembly 10 includes two sealing rings 101 and two sealing plugs 102. Both sealing rings 101 are mounted on the outer wall of the housing 1, corresponding to two air outlets 8. The two sealing plugs 102 are mounted on the side of the sealing rings 101 furthest from the air outlets 8. A rubber plug 103 is fixedly installed on the side of each sealing plug 102 closest to the sealing rings 101. The sealing plugs 102 engage with the sealing rings 101 via the rubber plugs 103. When sealing the air outlets 8 is required, the sealing plugs can be... The plug 102 is aligned with the sealing ring 101, and the rubber plug 103 is inserted into the sealing ring 101 through the sealing plug 102. The sealing plug 102 and the sealing ring 101 are matched through the rubber plug 103, and the sealing plug 102 can be processed to seal the sealing ring 101. This prevents dust from entering the welding machine through the seal between the cooling fan 9 and the air outlet 8 when the welding machine is not in use. When the welding machine is in use, the sealing plug 102 can be directly removed from the sealing ring 101.

[0030] Two handles 11 are installed on the top of the box cover 2, and multiple casters 12 are installed on the bottom of the casing 1. Both the handles 11 on the box cover 2 and the casters 12 on the bottom of the casing 1 facilitate the movement and transportation of the welding machine.
