Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a wire feeder. Background Art

[0002] During the welding process, the wire feeder transports the welding wire to the outside by rotating the internal wire reel. The wire feeder is usually equipped with a handle. In the welding scene, after one of the work tasks is completed, the worker needs to hold the handle to lift the wire feeder and adjust the working position.

[0003] The handle on the wire feeder under the existing technology is relatively short. When the wire reel is full of welding wire, the weight of the wire reel is relatively large. At this time, the center of gravity of the entire wire feeder is close to the position of the wire reel. The wire reel is located at the tail of the wire feeder, and the handle is generally located in the middle of the wire feeder. This will cause the worker to be far away from the center of gravity when holding the handle, and the wire feeder will fall backward and tilt in the worker's hand, resulting in difficulty in carrying. The tilting problem will occur in the process of moving the wire feeder. Similarly, if there is no welding wire on the wire reel, the weight of the entire wire feeder will be concentrated on the position of the electronic components on the front panel of the wire feeder. Similarly, the center of gravity at this time is far away from the handle in the middle, causing the wire feeder to tilt forward during movement, resulting in difficulty in carrying. In addition, today's handles are usually injection molded, which will make the handle weaker and may break. Utility Model Content

[0004] The purpose of the utility model is to provide a wire feeder, which solves the problems of tilting and laborious transportation during the transportation of the wire feeder in the prior art.

[0005] To achieve this object, the present invention adopts the following technical solution: the present invention provides a wire feeder, comprising a body, a front panel being installed on one side of the body, a bracket being installed on the side of the body away from the front panel, a wire reel cover being installed on the bracket, a rotating shaft being installed inside the wire reel cover, a welding wire reel being rotatably installed on the rotating shaft, welding wire being wound around the welding wire reel, and the welding wire being fed out along the front panel, the bottom of the rotating shaft being installed on a connecting rib, the connecting rib being connected to a handle sheet metal, the other end of the handle sheet metal being connected to the front panel, the outer periphery of the handle sheet metal being wrapped with an outer shell, and the hand is gripping the outer side of the outer shell.

[0006] Preferably, a first screw hole is formed at the bottom of the rotating shaft, a first through hole is opened on the connecting rib, a second through hole is formed on the wire reel cover, and a third through hole is formed on the bracket. The screw passes through the first through hole, the second through hole and the third through hole in sequence and is screwed into the first screw hole.

[0007] Preferably, the outer shell includes a first shell and a second shell, the first shell and the second shell are connected to each other to form a cavity, and the handle sheet metal is inserted into the cavity.

[0008] Preferably, the first shell and the second shell are made of plastic.

[0010] Preferably, the handle sheet metal is provided with a first connecting hole, the connecting rib is provided with a second connecting hole, and the bolt passes through the first connecting hole and the second connecting hole and is fastened with a nut.

[0011] Preferably, a slope is formed on a side of the housing close to the front panel, the slope is parallel to and connected to the front panel, and the top surface of the housing is tangent to the wire reel cover.

[0012] Beneficial effects: By extending the handle sheet metal and increasing the grip length, the hand can be positioned close to the center of gravity during the change of the wire feeder's center of gravity, thereby improving the stability of the mobile wire feeder. The handle sheet metal is connected to the front panel at the front end, so that the handle sheet metal can be close to the front panel, and the operator's hand can be closer to the front panel. When the wire reel is empty, the center of gravity moves forward, so that the hand coincides with the center of gravity, thereby improving the stability of the mobile wire feeder; the handle sheet metal is connected to the rotating shaft through connecting ribs, so that the gripping area of ​​the hand on the handle sheet metal is closer to the wire reel. When the wire reel is fully loaded, the hand moves backward close to the wire reel, so that the hand is tightened from the wire feeder, thereby improving the stability of the mobile wire feeder during movement and making it easier to carry.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0018] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0021] Under the existing technology, the length of the handle on the wire feeder is relatively short. When there is more or less welding wire on the wire reel, the center of gravity of the wire feeder will change, causing the worker's hand to be far away from the center of gravity. In this way, the wire feeder will shake during the process of carrying it, and there is a risk of falling.

[0022] In order to solve the above problems, Figures 1 to 3As shown, the utility model provides a wire feeder, which includes a body 1, a front panel 2 is installed on one side of the body 1, a bracket 3 is installed on the side of the body 1 away from the front panel 2, a wire reel cover 4 is installed on the bracket 3, a rotating shaft 5 is installed in the wire reel cover 4, a welding wire reel 6 is rotatably installed on the rotating shaft 5, the welding wire is wound around the wire reel 6, the welding wire is fed out along the front panel 2, a wire feeding hole is provided on the front panel 2, the welding wire is fed out along the wire feeding hole, the bottom of the rotating shaft 5 is installed on the connecting rib 7, the connecting rib 7 is connected to the handle sheet metal 8, the other end of the handle sheet metal 8 is connected to the front panel 2, the outer periphery of the handle sheet metal 8 is wrapped with an outer shell 9, and the hand holds the outer side of the outer shell 9.

[0023] By extending the length of the handle sheet metal 8 and adding connecting ribs 7, the rotating shaft 5 and the front panel 2 are connected. At the same time, since the handle sheet metal 8 and the front panel 2 are connected, when the center of gravity of the wire feeder moves toward the front panel 2 because the welding wire is not wound on its rotating shaft 5, the worker's hand can move forward along the handle sheet metal 8 so that the hand is placed directly above the center of gravity, shortening the horizontal distance between the hand and the center of gravity, reducing the degree of shaking of the wire feeder during movement, and reducing the torque received by the hand.

[0024] If there is a lot of welding wire on the wire reel 6, the center of gravity will move to one side of the wire reel 6, and the hand will move to the side close to the connecting rib 7, shortening the horizontal distance between the hand and the center of gravity of the wire feeder, reducing the torque applied to the hand, and improving stability during movement.

[0025] At the same time, the handle sheet metal 8 is connected to the rotating shaft 5 through the connecting rib 7, and the handle sheet metal 8 is directly connected to the front panel 2, so as to improve the integrity of the wire feeder, improve the structural strength of the wire feeder, and make the handle sheet metal 8 have a higher load-bearing capacity.

[0026] A first screw hole is formed at the bottom of the rotating shaft 5 of the present invention, a first through hole is opened on the connecting rib 7, a second through hole is formed on the wire reel cover 4, and a third through hole is formed on the bracket 3. The screw passes through the first through hole, the second through hole and the third through hole in sequence and is screwed into the first screw hole.

[0027] The wire reel cover 4 is fixed to the bracket 3 with screws, and then the connecting rib 7 is fixed to the bracket 3 with screws. The connecting rib 7 is installed with a rotating shaft 5, which facilitates subsequent disassembly and maintenance, and can reduce the difficulty of disassembly. The handle sheet metal 8 of this utility model is a 2mm thick steel plate to improve the load-bearing capacity. At the same time, the bracket 3 is a 1.5mm thick steel plate, which can also improve the load-bearing capacity.

[0028] The outer shell 9 includes a first shell 91 and a second shell 92. The first shell 91 and the second shell 92 are connected to each other to form a cavity. The handle sheet metal 8 is passed through the cavity. The worker's hands directly hold the outside of the first shell 91 and the second shell 92, which makes the grip feel better.

[0029] The first shell 91 and the second shell 92 of the present invention are made of plastic material, which makes the hand feel more comfortable, and the front panel 2 and the wire reel cover 4 are also made of plastic material, which can resist external impact and improve the structural strength of the wire feeder.

[0030] An opening 41 is provided on the side of the wire reel cover 4, and the handle sheet metal 8 is connected to the connecting rib 7 after passing through the opening 41, so that the pulling force of the handle sheet metal 8 can directly act on the position of the rotating shaft 5. When there is a lot of welding wire on the rotating shaft 5, moving the hand to the side close to the connecting rib 7 can stabilize the wire feeder and reduce the shaking amplitude.

[0031] The handle sheet metal 8 is provided with a first connecting hole, and the connecting rib 7 is provided with a second connecting hole. The bolts pass through the first connecting hole and the second connecting hole and are fastened with nuts. The connecting rib 7 and the handle sheet metal 8 are connected by bolts, so that the connecting rib 7 and the handle sheet metal 8 are easy to disassemble and connect, and are convenient for subsequent disassembly, inspection and installation.

[0032] A slope 93 is formed on one side of the shell 9 close to the front panel 2. The slope 93 is parallel to and connected to the front panel 2. Visually, the slope 93 is more integrated because it is connected to the front panel 2. The integrated slope 93 also makes the wire feeder more beautiful when viewed visually.

[0033] The top surface 94 of the housing 9 is tangent to the wire reel cover 4, so that the shape of the housing 9 is more compatible with the wire feeder and more aesthetically pleasing.

[0034] The above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to provide an exhaustive list of all possible embodiments.
