DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the prior art, when the welding machine is working, the air in the general factory contains impurities such as dust and moisture. Dust particles accumulate on the electrical components and wire loosening mechanism of the welding machine for a long time. The dust and other impurities cause poor heat dissipation of the electrical components, thereby causing the temperature of the electrical components to rise, thereby causing damage to the multi-directional inverter carbon dioxide gas shielded welding machine;

[0046] In order to solve the above problems, the main concept adopted in this embodiment is: by cooperating with the driving mechanism 5 and the cleaning mechanism 6, the driving mechanism 5 is used to squeeze the cleaning mechanism 6, so that the cleaning mechanism 6 can blow off the dust accumulated on the electronic components 4 in the box, so that the electronic components 4 can be cleaned in time, the temperature of the electronic components 4 is reduced, and the probability of damage to the welding machine is reduced.

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods;

[0048] The present invention provides a multi-directional inverter carbon dioxide gas shielded welding machine, comprising a body 1, a box 2 fixedly connected to the body 1, a wire feeding wheel 3 arranged in the box 2, and an electronic component 4 arranged on one side of the box 2; and further comprising:

[0049] Driving mechanism 5; the driving mechanism 5 is located in the box 2 and is used to provide power;

[0050] Cleaning mechanism 6; the cleaning mechanism 6 is located in the box 2 and is used to clean the electronic components 4;

[0051] When the multi-directional inverter carbon dioxide gas shielded welding machine starts working, the staff starts the wire feeding wheel 3. After the wire feeding wheel 3 is started, the driving mechanism 5 is driven to follow the wire feeding wheel 3 to make a circular motion; in the process of the driving mechanism 5 making a circular motion, the driving mechanism 5 squeezes and restores the cleaning mechanism 6, so that the cleaning mechanism 6 blows off the dust accumulated on the electronic components 4 in the air, thereby reducing the dust accumulated on the electronic components 4 that are continuously working; improving the heat dissipation effect of the electronic components 4, reducing the probability of damage to the welding machine, and increasing the service life of the welding machine, thereby improving the efficiency of the multi-directional inverter carbon dioxide gas shielded welding machine when welding products;

[0052] In the prior art, when the welding machine is working, there are impurities such as dust and moisture in the air in the factory, and the dust particles are accumulated on the electrical components of the welding machine for a long time, causing the temperature of the electrical components to rise continuously, thereby causing the multi-directional inverter carbon dioxide gas shielded welding machine to be damaged, thereby reducing the service life of the multi-directional inverter carbon dioxide gas shielded welding machine;

[0053] The present invention cooperates with the driving mechanism 5 and the cleaning mechanism 6, and utilizes the driving mechanism 5 to squeeze the cleaning mechanism 6, so that the cleaning mechanism 6 blows off the dust accumulated on the electronic components 4 in the box body 2, so that the electronic components 4 are cleaned in time, the temperature of the electronic components 4 is reduced, and the probability of damage to the welding machine is reduced.

[0054] As a specific implementation of the present invention, the driving mechanism 5 includes:

[0055] Rotating rod 51; one end of the rotating rod 51 is fixedly connected to one side of the wire feeding wheel 3;

[0056] Rotating wheel 52; the rotating wheel 52 is rotatably connected to the end of the rotating rod 51 away from the wire feeding wheel 3, and the rotating wheel 52 is in contact with the cleaning mechanism 6;

[0057] As a specific embodiment of the present invention, the cleaning mechanism 6 includes:

[0058] Support plate 61; the support plate 61 is fixedly connected to the inner wall of the box body 2;

[0059] Spherical airbag 62; the spherical airbag 62 is fixedly connected to the support plate 61, and the number is more than two and evenly distributed on the support plate 61 at the same radius with the axial direction of the wire feeding wheel 3 as the center, and the radius is the same as the radius from the rotating rod 51 to the axis of the wire feeding wheel 3;

[0060] One-way air intake valve 63; the one-way air intake valve 63 is arranged outside the spherical airbag 62 and is connected to the spherical airbag 62, and the number of the one-way air intake valve 63 is more than one;

[0061] One-way exhaust valve 64; the one-way exhaust valve 64 is disposed on a side of the support plate 61 away from the spherical airbag 62, penetrates the support plate 61, and is connected to the spherical airbag 62. The number of the one-way exhaust valve 64 is more than one;

[0062] Before the multi-directional inverter carbon dioxide gas shielded welding machine starts working, the spherical airbags 62 and the rotating wheel 52 are evenly distributed on the support plate 61 on the same radius with the axial direction of the wire feeding wheel 3 as the center, and the radius is the same as the radius from the rotating rod 51 to the axis of the wire feeding wheel 3. They are distributed in the same vertical plane, but are located at different radial positions. At this time, the rotating wheel 52 is not in contact with the spherical airbags 62. At this time, the staff starts the wire feeding wheel 3. After the wire feeding wheel 3 is started, it drives the rotating rod 51 to rotate, and at the same time, the rotating rod 51 drives the rotating wheel 52 to rotate. Since the wire feeding wheel 3 makes a circular motion in the process of conveying the welding wire, the rotating rod 51 and the rotating wheel 52 also make a circular motion under the action of the wire feeding wheel 3. In the process of the rotating wheel 52 making a circular motion, the rotating wheel 52 rotates During the process, it contacts with a spherical airbag 62 located in the same vertical plane and with the same radius. The contact point between the spherical airbag 62 and the rotating wheel 52 will be deformed, which reduces the volume of the spherical airbag 62, thereby increasing the internal air pressure of the spherical airbag 62. The one-way exhaust valve 64 opens under the action of the air pressure to allow the gas in the spherical airbag 62 to be ejected from the one-way exhaust valve 64. The ejected gas blows off the dust on the electronic component 4, thereby reducing the accumulation of dust and improving the surface cleanliness of the electronic component 4. At the same time, the exhausted gas speeds up the gas circulation rate in the box 2, reduces the large amount of heat generated by the continuous operation of the electronic component 4, reduces the probability of damage to the welder, and increases the service life of the welder, thereby improving the efficiency of the multi-directional inverter carbon dioxide gas shielded welder when welding products.

[0063] At the same time, a one-way air inlet valve 63 is provided on the outer side of the spherical airbag 62. When the rotating wheel 52 squeezes the spherical airbag 62, the one-way air inlet valve 63 is closed, and the gas in the spherical airbag 62 only flows out from the one-way exhaust valve 64 and blows toward the electronic component 4. When the rotating wheel 52 leaves the spherical airbag 62, the one-way exhaust valve 64 is closed. At this time, the spherical airbag 62 at the squeezed position gradually returns to its original state, and the one-way air inlet valve 63 opens. External gas enters from the one-way air inlet valve 63 and fills the spherical airbag 62, so that when the rotating wheel 52 squeezes the spherical airbag 62 again, sufficient gas can flow out, thereby achieving the effect of automatic opening and closing.

[0064] As a specific embodiment of the present invention, a dust removal mechanism 7 is provided in the box body 2, and the dust removal mechanism 7 includes:

[0065] Slide 71; the slide 71 is sleeved on the welding wire; it is used to remove dust on the welding wire;

[0066] A connecting rod 72; the connecting rod 72 is fixedly connected to one side of the slide cylinder 71;

[0067] A push rod 73; one end of the push rod 73 is fixedly connected to an end of the connecting rod 72 away from the slide cylinder 71;

[0068] A push rod 74; one end of the push rod 74 is fixedly connected to an end of the push rod 73 away from the connecting rod 72;

[0069] Support column 76; the support column 76 is fixedly connected to the bottom of the box body 2; a slide groove 761 is formed at one end of the support column 76 away from the bottom; the first push rod 74 is sleeved in the slide groove 761 and is slidably connected to the slide groove 761;

[0070] The second push rod 77 is hinged to the end of the first push rod 74 away from the push rod 73;

[0071] Cam 75; one end of the cam 75 is hinged to one end of the No. 2 push rod 77 away from the No. 1 push rod 74; the other end of the cam 75 is fixedly connected to one side of the wire feeding wheel 3 away from the rotating rod 51; used to drive the cam 75 to move;

[0072] When the wire feeding wheel 3 transports the welding wire, the rotating wire feeding wheel 3 drives the cam 75 to rotate, and the rotating cam 75 drives the hinged No. 2 push rod 77 and the wire feeding wheel 3 to perform circular motion together, and the No. 2 push rod 77 drives the No. 1 push rod 74 to reciprocate along the slide groove 761 on the support column 76, and the reciprocating No. 1 push rod 74 drives the push rod 73 and the connecting rod 72 to move, so that the connecting rod 72 drives the slide cylinder 71 to reciprocate along the surface of the welding wire, and the reciprocating slide cylinder 71 removes dust and moisture that falls on the surface of the welding wire in the air, thereby improving the cleanliness of the surface of the welding wire, reducing the dust from entering the wire feeding hose with the welding wire, reducing the possibility of dust clogging the wire feeding hose, reducing the friction of the welding wire against the inner wall in the wire feeding hose, and improving the service life of the welding machine; at the same time, during welding, the hydrogen content in the weld is reduced, thereby improving the quality of the finished weld.

[0073] As a specific embodiment of the present invention, a brush 78 is adhered to the inner wall of the slide cylinder 71;

[0074] When the wire feeding wheel 3 delivers the welding wire, dust in the air will fall on the wire. When the dust removing mechanism 7 makes a reciprocating motion, the slide cylinder 71 in the dust removing mechanism drives the brush 78 fixed to the inner wall of the slide cylinder 71 to make a reciprocating motion. The reciprocating brush 78 brushes away the dust falling on the welding wire in the air, thereby improving the cleanliness of the welding wire surface, reducing the hydrogen content in the weld, and thus improving the quality of the finished weld. At the same time, it reduces the content of dust entering the tube with the movement of the welding wire, reduces the possibility of dust clogging the welding wire tube, and further improves the service life of the welding machine.

[0075] As a specific embodiment of the present invention, the brush 78 is made of PBT wire;

[0076] Since the brush 78 is in direct contact with the welding wire, the material of the brush 78 is PBT wire, which is relatively soft. When cleaning the surface of the welding wire, the brush 78 made of PBT wire avoids scratching the cleaned area of ​​the welding wire, thereby improving the quality of the welding wire.

[0077] As a specific embodiment of the present invention, a No. 1 spring 8; the No. 1 spring 8 is fixedly connected to one side of the wire column;

[0078] No. 2 spring 9; the No. 2 spring 9 is fixedly connected to the inner wall of the box body 2;

[0079] When the dust removal mechanism 7 makes reciprocating motion, in order to reduce the possibility of damage to the wire post and the inner wall of the box body 2 caused by the impact force of the dust removal mechanism 7, a No. 1 spring 8 and a No. 2 spring 9 are provided, so that the dust removal mechanism 7 can avoid direct collision with the wire post and the inner wall of the box body 2 when making reciprocating motion. At the same time, the spring provides a buffering effect to the dust removal mechanism, thereby reducing the probability of damage to the dust removal mechanism 7, thereby increasing the service life of the multi-directional inverter carbon dioxide gas shielded welding machine.

[0080] As a specific embodiment of the present invention, a clamping plate 11 and a tripod 12 are fixedly connected to the top of the main body for fixing the carbon dioxide tank; a rubber 15 is provided between the clamping plate 11 and the tripod 12 and the carbon dioxide tank;

[0081] The carbon dioxide tank is placed on the clamping plate 11 and the tripod 12. When the staff moves the welding machine, the carbon dioxide tank may be offset or slide off the main body, affecting the working efficiency of the welding machine. Therefore, an anti-slip rubber 15 is provided between the contact surface of the carbon dioxide tank and the clamping plate 11 to increase the friction between the two, improve the safety of the device, avoid the displacement of the carbon dioxide tank or the impact of falling off the main body, thereby avoiding unnecessary dangers, thereby improving the safety of the staff and improving the working efficiency of the welding machine.

[0082] As a specific embodiment of the present invention, a universal wheel 13 is provided at the bottom of the body 1;

[0083] As a specific embodiment of the present invention, a telescopic plate 14 is provided around the universal wheel 13;

[0084] Since the position of the multi-directional inverter carbon dioxide gas shielded welding machine needs to change during use, the universal wheel 13 can make the welding machine more sensitive when moving; at the same time, when the welding machine moves to the specified position, the staff lightly steps on the telescopic plate 14, and the telescopic plate 14 moves down, so that the universal wheel 13 is wrapped front and back, and then the welding machine is in a fixed position, which increases the stability of the work; after the work is completed, the staff lightly steps on the telescopic plate 14 again, so that the telescopic plate 14 is lifted, and then the welding machine can be moved to the next location, which improves the practicality of the welding machine.

[0085] The specific workflow is as follows:

[0086] Before the multi-directional inverter carbon dioxide gas shielded welding machine starts working, the rotating wheel 52 is in the middle of the spherical airbag 62, where the rotating wheel 52 is not in contact with the spherical airbag 62. At this time, the staff starts the wire feeding wheel 3. After the wire feeding wheel 3 is started, it drives the rotating rod 51 to rotate, and at the same time, the rotating rod 51 drives the rotating wheel 52 to rotate. Since the wire feeding wheel 3 makes a circular motion in the process of conveying the welding wire, the rotating rod 51 and the rotating wheel 52 also make a circular motion under the action of the wire feeding wheel 3. In the process of the rotating wheel 52 making a circular motion, the rotating wheel 52 squeezes the spherical airbag 62 during the rotation process, and the contact between the rotating wheel 52 and the spherical airbag 62 will be deformed, so that the spherical airbag The volume of the spherical airbag 62 is reduced, thereby increasing the air pressure inside the spherical airbag 62. When the air pressure inside the spherical airbag 62 reaches the pressure value set by the one-way exhaust valve 64, the one-way exhaust valve 64 opens to allow the gas inside the spherical airbag 62 to be ejected from the one-way exhaust valve 64. The exhausted gas blows off the dust on the electronic component 4, thereby reducing the accumulation of dust and improving the surface cleanliness of the electronic component 4. At the same time, the exhausted gas speeds up the gas circulation rate inside the box 2, reduces the large amount of heat generated by the continuous operation of the electronic component 4, reduces the probability of damage to the welder, and increases the service life of the welder, thereby improving the efficiency of the multi-directional inverter carbon dioxide gas shielded welder when welding products.

[0087] At the same time, a one-way air inlet valve 63 is provided on the outer side of the spherical airbag 62. When the rotating wheel 52 squeezes the spherical airbag 62, the one-way air inlet valve 63 is closed, and the gas in the spherical airbag 62 only flows out from the one-way exhaust valve 64 and blows toward the electronic component 4. When the rotating wheel 52 leaves the spherical airbag 62, the pressure of the spherical airbag 62 does not reach the pressure value of the one-way exhaust valve 64, and the one-way exhaust valve 64 is closed. At this time, the spherical airbag 62 at the squeezed position gradually returns to its original state, and the one-way air inlet valve 63 is opened. External gas enters from the one-way air inlet valve 63 and fills the spherical airbag 62, so that when the rotating wheel 52 squeezes the spherical airbag 62 again, sufficient gas can flow out, thereby achieving the effect of automatic opening and closing.

[0088] When the wire feeding wheel 3 transports the welding wire, the rotating wire feeding wheel 3 drives the cam 75 to rotate, and the rotating cam 75 drives the hinged No. 2 push rod 77 and the wire feeding wheel 3 to make a circular motion together, and the No. 2 push rod 77 drives the No. 1 push rod 74 to reciprocate along the slide groove 761 on the support column 76, and the reciprocating No. 1 push rod 74 drives the push rod 73 and the connecting rod 72 to move, so that the connecting rod 72 drives the slide cylinder 71 to reciprocate along the surface of the welding wire, and the reciprocating slide cylinder 71 removes the dust and moisture that falls on the surface of the welding wire in the air, thereby improving the cleanliness of the welding wire surface, reducing the dust from entering the wire feeding hose along with the welding wire, and reducing the possibility of dust clogging the wire feeding hose. In order to reduce the friction between the welding wire and the inner wall of the wire feeding hose, a No. 1 spring 8 and a No. 2 spring 9 are provided, so that the dust removal mechanism 7 can avoid direct collision with the wire column and the inner wall of the box body 2 when making reciprocating motion. At the same time, the spring provides a buffering effect to the dust removal mechanism, thereby reducing the probability of damage to the dust removal mechanism 7 and improving the service life of the welding machine; at the same time, during welding, the hydrogen content in the weld is reduced, thereby improving the quality of the finished weld; at the same time, a slider 77 is sleeved on the push rod 73, and the slider 77 is rotatably connected to the support column 76, which can change with the swing of the push rod 73, giving the push rod 73 an additional support point, thereby avoiding the connection rod 72 from rotating and contacting the bottom of the box body 2;

[0089] The carbon dioxide tank is placed on the clamping plate 11 and the tripod 12. When the worker moves the welding machine, the carbon dioxide tank may be offset or slide off the main body 1, affecting the efficiency of the welding machine. Therefore, an anti-skid rubber 15 is provided between the contact surface of the carbon dioxide tank and the clamping plate 11 to increase the friction between the two, improve the safety of the device, avoid the displacement of the carbon dioxide tank or the impact of falling off the main body 1, and generate unnecessary dangers, thereby improving the safety of the workers and improving the working efficiency of the welding machine;

[0090] Since the position of the multi-directional inverter carbon dioxide gas shielded welding machine needs to change during use, the universal wheel 13 can make the welding machine more sensitive when moving; at the same time, when the welding machine moves to the specified position, the staff lightly steps on the telescopic plate 14, and the telescopic plate 14 moves down, so that the universal wheel 13 is wrapped front and back, and then the welding machine is in a fixed position, which increases the stability of the work; after the work is completed, the staff lightly steps on the telescopic plate 14 again, so that the telescopic plate 14 is lifted, and then the welding machine can be moved to the next location, which improves the practicality of the welding machine.
