Description
Technical Field
[0001] This application relates to the field of flux-cored wire packaging technology, and in particular to an auxiliary tool for vacuum packaging flux-cored wire. Background Technology
[0002] Flux-cored welding wire can be used to weld various steel structural components, including low-carbon steel, high-strength steel, low-temperature steel, heat-resistant steel, stainless steel, and wear-resistant surfacing. The manufacturing methods of flux-cored welding wire can be broadly divided into three types: steel tube method, steel strip method, and coil method. Currently, the more mature manufacturing methods in my country are the steel strip method and the coil method.
[0003] Regardless of the manufacturing method of flux-cored welding wire, a vacuum packaging machine is required when packaging the finished welding wire. The specific operation is as follows: The worker first opens the top cover of the vacuum packaging machine, then takes out an aluminum foil bag and tears open the foil bag with his fingers. To ensure that the finished welding wire roll can be smoothly put into the aluminum foil bag, another worker needs to assist in placing the finished welding wire roll vertically into the aluminum foil bag. Then, the aluminum foil bag is laid down in the vacuum chamber of the vacuum packaging machine, and its opening is placed on the heating strip and leveled. Then, the top cover is pressed down, the equipment is turned on, and the packaged flux-cored welding wire is vacuum sealed. After the vacuuming is completed, the top cover is opened. In order to facilitate subsequent transportation and convenient storage of the packaged flux-cored welding wire, the worker also needs to press the four corners of the aluminum foil bag to be tightly attached to the flux-cored welding wire. Existing vacuum packaging machines lack auxiliary tools to assist workers in packaging finished flux-cored welding wires. Therefore, there is an urgent need to provide an auxiliary tool to assist workers in packaging finished flux-cored welding wires to improve the convenience of the flux-cored welding wire production process. Utility Model Content
[0004] This application provides an auxiliary tool for vacuum packaging of flux-cored welding wire, which can assist workers in their operation when using a vacuum packaging machine to package finished flux-cored welding wire.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: A vacuum packaging auxiliary tool for flux-cored welding wire includes two parallel lateral support frames, the lower ends of which can be installed in the vacuum chamber of a vacuum packaging machine. A support bracket is movably installed at the middle position of the two lateral support frames, and the support bracket can rotate up and down around its connection point with the lateral support frame; Furthermore, when the support frame is in a vertical position, it can be used in conjunction with workers to open the opening of the aluminum foil bag; The support frame is equipped with a support bed on the side near the heating strip of the vacuum packaging machine.
[0006] Furthermore, the support bracket is made of a single metal rod bent into shape. The support bracket is in the shape of a U.S. shape. A rotating shaft is welded to each side of the closed end opposite to the groove end of the support bracket. The two rotating shafts are respectively inserted into the middle of the two lateral support brackets on their close sides, and the rotating shafts are rotatably connected to the lateral support brackets connected to them.
[0007] Furthermore, the overall height of the support bracket is greater than the diameter of the finished flux-cored welding wire.
[0008] Furthermore, the plane containing the groove segment on the support bracket has an angle with the plane containing its main body, and this angle is an acute angle.
[0009] Furthermore, a notch is cut at each end of the two lateral support frames that are close to each other.
[0010] Furthermore, the support bed includes a first mounting plate and a second mounting plate that are parallel to each other and fixedly connected to both of the two lateral support frames. The first mounting plate is located on the upper side of the connection point between the support bracket and the lateral support frame. When the support bracket is in a vertical state, the side of the first mounting plate away from the vacuum packaging machine heating strip is in contact with the support bracket. The second mounting plate is located above the notch on the side of the lateral support frame near the vacuum packaging machine heating strip. Multiple grid strips are evenly installed between the first mounting plate and the second mounting plate, and the grid strips are perpendicular to both the first mounting plate and the second mounting plate.
[0011] Furthermore, one of the lateral support frames has an arc-shaped shaping groove installed on the outer side near the heating strip of the vacuum packaging machine, and a reinforcing diagonal brace is welded to the outer side of the arc-shaped shaping groove.
[0012] In summary, this application includes at least one of the following beneficial technical effects: When a worker needs to package the finished flux-cored welding wire, the opening support frame can be raised first. Using the support frame and one of the worker's hands, the opening of the aluminum foil bag is opened. Then, the worker's other hand can hold the finished flux-cored welding wire and vertically place it into the aluminum foil bag. Next, the opening of the aluminum foil bag is released, allowing it to close naturally, and the bag is detached from the support frame. The support bed provides support for the bagged flux-cored welding wire. The aluminum foil bag is then laid down on the support bed towards the heating strip of the vacuum packaging machine. The opening of the aluminum foil bag is secured with the pressure rod at the heating strip, and the top cover of the vacuum packaging machine is closed. The equipment is then started to perform the final vacuum sealing operation. This auxiliary tool, installed in the item placement chamber of the vacuum packaging machine, allows a single worker to complete the packaging of the finished flux-cored welding wire, reducing labor costs in the production process, improving worker convenience, and offering a simple structure that is easy to manufacture.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0017] like Figures 2-5 As shown, this application discloses a vacuum packaging auxiliary tool for flux-cored welding wire, which includes two parallel lateral support frames 1, the lower ends of which can be installed in the vacuum chamber 3 of the vacuum packaging machine 2. A support bracket 4 is movably installed at the middle position of the two lateral support frames 1. The support bracket 4 can rotate up and down around its connection point with the lateral support frame 1. Furthermore, when the support bracket 4 is in a vertical position, it can work with the worker to open the opening of the aluminum foil bag; A support bed 5 is provided on the side of the support frame 4 near the heating strip 10 of the vacuum packaging machine 2.
[0018] In the above embodiments, the finished flux-cored welding wire is the product after the processed flux-cored welding wire has been fed out by a wire feeding machine, surface treated, and wound onto a special I-beam reel. The diameter of the finished flux-cored welding wire is generally about 20-26 cm. To ensure complete wrapping of the finished flux-cored welding wire, the shorter side of the aluminum foil bag used must be at least greater than the diameter of the finished flux-cored welding wire. Commonly used aluminum foil bag sizes are 30×42 cm. When using the aluminum foil bag, the worker needs to open the bag opening. Because the aluminum foil bag is relatively soft, one worker typically needs to hold the bag open with both hands while another worker inserts the finished flux-cored welding wire through the open opening. If the bottom of the aluminum foil bag is located on the vacuum chamber 3 of the vacuum packaging machine 2 (i.e., the space in the vacuum packaging machine 2 specifically for placing the product to be packaged; if...), Figure 1 As shown in the diagram, which is a structural schematic of a commonly used vacuum packaging machine 2 in the prior art, when the finished flux-cored welding wire slides down the wall of the aluminum foil bag, it is easy to collide with the rigid wall plate of the vacuum chamber 3, causing unnecessary impact to the finished flux-cored welding wire. If the worker who opens the aluminum foil bag suspends the bag in the air, the worker's hand needs to bear the impact force when the finished flux-cored welding wire slides down.
[0019] The specific length of the side support frame 1 in this application can be designed according to the actual length of the vacuum chamber 3 of the vacuum packaging machine 2 used by the enterprise. The two side support frames 1 can be fixed in the vacuum chamber 3 of the vacuum packaging machine 2 by welding or bonding. This avoids drilling holes in the vacuum packaging machine 2, so as to avoid affecting the airtightness of the vacuum packaging machine 2 when it is used due to improper installation.
[0020] After the auxiliary tool of this application is installed in the vacuum packaging machine 2, when the worker needs to perform packaging operations on the finished flux-cored welding wire, the opening support frame 4 between the two lateral support frames 1 can be lifted first. The opening support frame 4 and one of the worker's hands are used to open the opening of the aluminum foil bag. Then, the worker's other hand can hold the finished flux-cored welding wire and vertically put it into the aluminum foil bag. Next, the hand holding the opening of the aluminum foil bag is released, allowing it to close naturally, and the aluminum foil bag is removed from the opening support frame 4. The support bed 5 can provide support for the bagged flux-cored welding wire. The support bed 5 of this application can be made of elastic material or soft material, so that even if the finished flux-cored welding wire suddenly falls under the action of gravity during the bagging process, unnecessary bumps and knocks can be avoided.
[0021] Next, on the support bed 5, the worker lays the aluminum foil bag down towards the heating strip 10 of the vacuum packaging machine 2. After securing the bag opening with the pressure bar at the heating strip 10, the top cover of the vacuum packaging machine 2 can be closed, and the equipment can be started to perform the final vacuum sealing operation. The auxiliary tool of this application, installed in the item placement chamber of the vacuum packaging machine 2, allows a single worker to complete the packaging of finished flux-cored welding wire, reducing labor costs in the production process, improving worker convenience, and featuring a simple structure that is easy to manufacture.
[0022] Furthermore, such as Figure 2 and Figure 3 As shown, the support bracket 4 is made of a single metal rod bent into shape. The support bracket 4 is in the shape of a "U". A rotating shaft 6 is welded to each side of the closed end opposite to the groove end of the support bracket 4. The two rotating shafts 6 are respectively inserted into the middle of the two lateral support brackets 1 on the adjacent sides, and the rotating shafts 6 are rotatably connected to the lateral support brackets 1 connected to them.
[0023] In the above embodiments, the support frame 4 is rotatably connected to the lateral support frame 1 via a pivot 6. This allows the worker to easily straighten the support frame 4 during use and quickly lower it after completing the bagging operation of the finished flux-cored welding wire. The width of the groove section on the support frame 4 is smaller than the width of the aluminum foil bag and not smaller than the diameter of the finished flux-cored welding wire reel to be packaged. This ensures that after one side of the aluminum foil bag is placed over the groove section of the support frame 4, the opening of the aluminum foil bag, which is opened with the worker's assistance, can be smoothly inserted into the finished flux-cored welding wire reel.
[0024] Furthermore, the overall height of the support bracket 4 is greater than the diameter of the finished flux-cored welding wire.
[0025] In the above embodiments, after completing the bagging operation of the finished flux-cored wire, the opening of the aluminum foil bag needs to be removed from the support bracket 4. If the overall height of the support bracket 4 is less than the diameter of the finished flux-cored wire, part of the flux-cored wire will still be located outside the aluminum foil bag during bagging. When the opening of the aluminum foil bag is then removed from the grooved section of the support bracket 4, more of the flux-cored wire will be exposed. This not only increases the wrinkles in the aluminum foil bag but also increases the risk of the finished flux-cored wire detaching from the aluminum foil bag. In this application, the overall height of the support bracket 4 is set to be greater than the diameter of the finished flux-cored wire, and the height of the grooved part of the support bracket 4 is less than half the diameter of the finished flux-cored wire. This effectively solves the above problems when performing the bagging operation in the above manner.
[0026] Furthermore, such as Figure 3 As shown, the plane containing the groove section on the support bracket 4 forms an angle with the plane containing its main body, and this angle is an acute angle.
[0027] In the above embodiments, the opening support frame 4 is set up as described above. When the worker adjusts the opening support frame 4 to a vertical position, the grooved section on the opening support frame 4 will be tilted towards the heating strip 10 of the vacuum packaging machine 2. This facilitates the worker to quickly place one side of the aluminum foil bag opening onto the grooved section of the opening support frame 4. The angle between the plane of the grooved section of the opening support frame 4 and the plane of its main body is generally set within 5°. If the angle is too large, the risk of the aluminum foil bag slipping off the grooved section of the opening support frame 4 will increase during the process of opening the aluminum foil bag in coordination with the worker's hand.
[0028] Furthermore, such as Figure 2 and Figure 5 As shown, each of the two lateral support frames 1 has a notch 7 cut at its two ends that are close to each other.
[0029] In the above embodiments, the notch 7 on the side of the lateral support frame 1 away from the heating strip 10 of the vacuum packaging machine 2 can be used to place the mouth support auxiliary frame 4 before vacuuming. The notch 7 on the side closer to the heating strip 10 of the vacuum packaging machine 2 can make the adjacent side of the support bed 5 as close as possible to the heating strip 10, so as to reduce the suspended section of the aluminum foil bag when it is laid flat.
[0030] Furthermore, such as Figure 4 and Figure 5As shown, the support bed 5 includes a first mounting plate 51 and a second mounting plate 52 that are parallel to each other and fixedly connected to both lateral support frames 1. The first mounting plate 51 is located on the upper side of the connection point between the support auxiliary frame 4 and the lateral support frame 1. When the support auxiliary frame 4 is in a vertical state, the side of the first mounting plate 51 away from the heating strip 10 of the vacuum packaging machine 2 is in contact with the support auxiliary frame 4. The second mounting plate 52 is located above the notch 7 on the side of the lateral support frame 1 near the heating strip 10 of the vacuum packaging machine 2. Multiple grid strips 53 are evenly installed between the first mounting plate 51 and the second mounting plate 52, and the grid strips 53 are perpendicular to both the first mounting plate 51 and the second mounting plate 52.
[0031] In the above embodiments, the first mounting horizontal plate 51 of this application is positioned between the two lateral support frames 1, diagonally above the pivot 6 on the support auxiliary frame 4 near the heating strip 10 of the vacuum packaging machine 2. When the support auxiliary frame 4 is in a vertical state, the two can just abut against each other. Thus, after one side of the aluminum foil bag opening is placed in the groove section of the support auxiliary frame 4, when one of the worker's hands pulls the other side of the aluminum foil bag toward the heating strip 10 of the vacuum packaging machine, the first mounting horizontal plate 51 can limit the support auxiliary frame 4 to keep it in a vertical state, thereby achieving the effect of opening the aluminum foil bag opening. In actual production, the position of the first mounting plate 51 can be adjusted to be directly above the rotating shaft 6. In this way, when the support bracket 4 swings upward, it will not be completely vertical, but will tilt slightly away from the heating strip 10 of the vacuum packaging machine 2. After the bagging operation of the finished core welding wire is completed, the worker removes the aluminum foil bag from the groove section of the support bracket 4. The support bracket 4 will automatically fall down under its own weight at the notch 7 on the side of the side support frame 1 away from the heating strip 10 of the vacuum packaging machine 2, saving the worker the trouble of manually laying it down.
[0032] The second mounting plate 52 of this application is located at the notch 7 on the side of the two lateral support frames 1 near the heating strip 10 of the vacuum packaging machine 2. This allows the first mounting plate 51, the second mounting plate 52, and the grid strip 53 between them to form a full-coverage structure on the side of the support frame 4 near the heating strip 10 of the vacuum packaging machine 2, providing ample support area for the aluminum foil bag. The grid strip 53 of this application can be made of rigid plastic. During bagging, the lower end of the aluminum foil bag is placed on the grid strip 53. When the finished flux-cored wire falls rapidly under gravity, the low hardness of the plastic material reduces the risk of damage even if the wire collides with it. Alternatively, the grid strip 53 can be made of elastic spring strips or high-temperature resistant rubber strips. Similarly, when the finished flux-cored wire falls rapidly under gravity, the spring strips or rubber strips can cushion the wire with their elasticity, thus reducing the risk of the wire colliding with the support due to rapid descent.
[0033] Furthermore, such as Figure 2 and Figure 4 As shown, an arc-shaped shaping groove 8 is installed on the outer side of one of the lateral support frames 1 near the heating strip 10 of the vacuum packaging machine 2, and a reinforcing diagonal brace 9 is welded to the outer side of the arc-shaped shaping groove 8.
[0034] In the above embodiments, after vacuuming and sealing operations are completed using vacuum packaging machine 2, the overall outline of the aluminum foil bag is still rectangular. This structure has many inconveniences when packing, transporting or storing. The traditional method is for workers to bend the four corners of the aluminum foil bag toward the finished flux-cored wire. After bending, pressure must be maintained for a certain period of time to ensure that the overall shape of the finally packaged aluminum foil bag is close to the external shape of the finished flux-cored wire.
[0035] In this application, an arc-shaped shaping groove 8 is set on one of the side support frames 1 in the manner described above. After the vacuuming and sealing operations are completed, the worker can put one end of the aluminum foil bag into the arc-shaped shaping groove 8. The worker can quickly complete the shaping operation of that end of the aluminum foil bag by using its own weight and the pressure of the worker's hand. Then, the other end of the aluminum foil bag is treated in the same way, so that the four corners of the packaged aluminum foil bag can be quickly bent towards the center of the finished flux-cored welding wire.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
