Description

Technical Field

[0001] This utility model relates to the field of welding wire spool technology, specifically to an adjustable welding wire spool for winding welding wire. Background Technology

[0002] In modern industrial production, welding wire, as an indispensable key material in the welding process, is widely used in various metal processing fields. Whether in the production stage or the subsequent packaging process, the connection between the welding wire spool and the rotating shaft of the winding device is involved. Welding wire is typically wound on a spool for easy storage, transportation, and use.

[0003] For example, a welding wire spool disclosed in patent application CN217102530U on August 2, 2022, features an innovative structural design. This spool consists of two opposing supports, with the inner and outer rings of the supports connected and fixed by support rods. The two inner rings are securely connected by multiple second crossbars, and a first crossbar connects the support rods of the two supports, with all first crossbars arranged on the same circumferential surface. A connecting plate is positioned on the outer end face of one of the supports, outside the inner ring, and an insertion hole is formed on the connecting plate. This frame-like metal component design not only saves on mold costs and reduces overall weight through the frame structure, but also extends the service life of the metal material, effectively reducing production costs. Furthermore, the connecting plate and its insertion hole match the pins on the wire-drawing fixture, forming a structure where the welding wire spool and the baffle rotate synchronously, ensuring the quality of the welding wire spool.

[0004] However, this welding wire spool has a drawback: its inner diameter is fixed and cannot be adjusted. This makes it extremely inconvenient to mount the spool onto the rotating shaft during actual operation, especially when the inner diameter of the rotating shaft is close to that of the welding wire spool, which further increases the difficulty of installation.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an adjustable wire spool for winding welding wire, which solves the technical problem that the inner diameter of the wire spool in the related art is fixed and cannot be adjusted. This makes the process of mounting the wire spool on the rotating shaft in actual operation extremely inconvenient, especially when the inner diameter of the rotating shaft is close to that of the wire spool, which further increases the difficulty of installation.

[0007] According to one aspect, at least one embodiment of this disclosure provides an adjustable wire spool for winding welding wire, comprising:

[0008] The welding wire spool body and the supporting inner shell, wherein the supporting inner shell is disposed inside the welding wire spool body;

[0009] A support connection assembly is disposed inside the welding wire spool body;

[0010] Several columns and clamping assemblies, wherein the columns are fixed to the bottom of the inner supporting shell and the clamping assemblies are disposed on the columns;

[0011] The support connection assembly includes several grooves, all of which are formed on the top of the welding wire spool body. The support inner shell is located inside the welding wire spool body. A locking block is provided around the side surface of the support inner shell, and the locking block is inserted into the groove.

[0012] As a further technical solution, a number of rectangular openings are provided around the side surface of the inner supporting shell, and a number of inner columns are provided on the side surface of the inner supporting shell, with the inner columns corresponding to the rectangular openings.

[0013] As a further technical solution, a support block is slidably connected to the inner column, the outer end of the support block is located inside the rectangular opening, and a stud is screwed to the top of the inner support shell, with a push block provided at the lower end of the stud.

[0014] As a further technical solution, the clamping assembly includes several circular grooves, all of which are formed on the side end face of the column. A pressure spring is provided in each circular groove, and the output end of the pressure spring is connected to a clamping frame.

[0015] As a further technical solution, the clamping frame is movably mounted on the outside of the column, and the surface of the clamping frame is provided with a number of anti-slip protrusions, the lower end face of the anti-slip protrusions being an inclined transition structure.

[0016] As a further technical solution, the clamping frame has an overall U-shaped structure, and the surface of the clamping frame located at the anti-slip convex layer is a concave structure surface.

[0017] As a further technical solution, a sliding plate is provided on the lower end face of the clamping frame, and the sliding plate is fixed at an inclined angle.

[0018] As a further technical solution, the anti-slip raised layer is made of hard rubber.

[0019] As a further technical solution, the grooves are arranged in a cross shape with relatively opposite points.

[0020] As a further technical solution, the outer end face of the support block is an arc-shaped structural surface.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. In this disclosure, through the design of the support connection component, the inner support shell and the welding wire spool body are connected by a plug-in type of clip and groove, which is convenient for installation. The support block on the side surface of the inner support shell is adjustable and can be adjusted according to the inner diameter of the welding wire spool body with different inner diameters. This solves the problem of fixed inner diameter of welding wire spool and inconvenient installation in related technologies. In particular, when the rotation shaft is close to the inner diameter of the welding wire spool, the installation difficulty is reduced and the installation efficiency is improved.

[0023] 2. In this disclosure, the clamping assembly utilizes the elastic force provided by the pressure spring to tightly clamp the clamping frame onto the shaft of the winding equipment. In conjunction with the anti-slip protrusion, the friction is increased to ensure that the welding wire spool is tightly connected to the winding equipment during the winding process, preventing loosening and ensuring the smooth progress of the winding process.

[0038] like Figures 1-6 As shown, an adjustable wire spool for winding welding wire is illustrated in one embodiment of this disclosure, comprising:

[0039] The welding wire spool body 1 and the supporting inner shell 2 are arranged inside the welding wire spool body 1.

[0040] Support connection component 4 is disposed inside the welding wire spool body 1;

[0041] Several columns 3 and clamping components 5 are provided. The columns 3 are fixed to the bottom of the inner supporting shell 2, and the clamping components 5 are provided on the columns 3.

[0042] The support connection assembly 4 includes several grooves 4-1, all of which are formed on the top of the welding wire spool body 1. The support inner shell 2 is located inside the welding wire spool body 1. A locking block 4-2 is provided around the side surface of the support inner shell 2, and the locking block 4-2 is inserted into the groove 4-1. Several rectangular openings 4-3 are formed around the side surface of the support inner shell 2. Several inner posts 4-4 are provided on the side surface of the support inner shell 2, and the inner posts 4-4 are positioned corresponding to the rectangular openings 4-3. A support block 4-5 is slidably fitted onto the inner post 4-4, and the outer end of the support block 4-5 is located inside the rectangular opening 4-3. A stud 4-6 is screwed to the top of the support inner shell 2, and a push block 4-7 is provided at the lower end of the stud 4-6.

[0043] In some examples, to achieve a stable and flexible connection between the inner support shell 2 and the wire spool, a support connection component 4 is designed. Multiple grooves 4-1 are evenly distributed on the top of the wire spool body 1. These grooves 4-1 are arranged in a regular pattern and match the locking blocks 4-2 set around the side surface of the inner support shell 2. When installing the inner support shell 2, simply place the inner support shell 2 accurately into the wire spool body 1, ensuring that the locking blocks 4-2 are precisely aligned with the grooves 4-1. With a gentle press, the locking blocks 4-2 will lock into the grooves 4-1. This plug-in connection method is not only simple and convenient to operate, but also stable and reliable. It effectively restricts the radial and circumferential movement of the inner support shell 2 inside the wire spool body 1. Even when the wire spool rotates at high speed or is subjected to a certain external force impact, the inner support shell 2 can remain stable.

[0044] The inner shell 2 has several rectangular openings 4-3 around its circumference. These rectangular openings 4-3 are evenly distributed along the circumference of the inner shell 2. The inner shell 2 also has several inner pillars 4-4 on its side surface. Each inner pillar 4-4 corresponds to one of the rectangular openings 4-3, and the position of the inner pillars 4-4 is precise to ensure a tight fit with the rectangular openings 4-3, facilitating the sliding of the support block 4-5. The support block 4-5 has a special block structure. One end of the support block 4-5 has a through hole that fits the inner pillar 4-4 and is fitted onto the inner pillar 4-4. The other end is located inside the rectangular opening 4-3. This design allows the support block 4-5 to slide flexibly on the inner pillar 4-4. During the sliding process, the rectangular openings 4-3 can limit and guide the support block 4-5, ensuring that the support block 4-5 always moves in the correct direction.

[0045] The support connection assembly 4 demonstrates strong adaptability when dealing with welding wire spools of different sizes. Since the inner diameter of the rotating shaft varies for different welding wire spools, the position of the support block 4-5 can be flexibly adjusted according to the actual diameter of the rotating shaft when supporting welding wire spools of different sizes is required. For example, when encountering a welding wire spool rotating shaft with a larger inner diameter, the operator can manually slide the support block 4-5 outward along the inner post 4-4 to increase the extension length of the support block 4-5, allowing the support block 4-5 to better fit against the inner wall of the rotating shaft and provide more stable support. Conversely, when encountering a rotating shaft with a smaller inner diameter, the support block 4-5 is slid inward to shorten its extension length, so as to avoid interference between the support block 4-5 and the rotating shaft, while ensuring good contact between the support block 4-5 and the rotating shaft and providing appropriate support.

[0046] In addition, a stud 4-6 is threadedly connected to the top of the inner support shell 2. The threads on the top of the inner support shell 2 are precision machined with a uniform pitch, ensuring that the stud 4-6 can move smoothly up and down during rotation. A push block 4-7 is provided at the lower end of the stud 4-6. Its bottom is a flat surface or a specific curved surface that matches the top of the support block 4-5, which can evenly transmit the force of the stud 4-6 to the support block 4-5. When the position of the support block 4-5 needs to be adjusted, the operator rotates the stud 4-6. When the stud 4-6 is rotated clockwise, the stud 4-6 gradually moves downward under the action of the threads on the top of the inner support shell 2, thereby driving the push block 4-7 to move downward. During the downward movement, the pushing block 4-7 contacts the top of multiple support blocks 4-5 and applies pressure, causing the support blocks 4-5 to slide outward along the inner column 4-4, thereby supporting the rotating shafts of welding wire reels with different inner diameters. Conversely, rotating the stud 4-6 counterclockwise moves the stud 4-6 upward, and the pushing block 4-7 also rises. Under its own weight or other auxiliary external forces, the support blocks 4-5 slide inward, shortening their extension length. In this way, the extension length of the support blocks 4-5 can be precisely controlled, ensuring that the inner shell 2 can achieve good matching with the rotating shafts of welding wire reels with different inner diameters, effectively improving the versatility and practicality of the equipment.

[0047] like Figures 1-6 As shown, this embodiment proposes a clamping assembly 5 including several circular grooves 5-1, all of which are opened on the side end face of the column 3. A pressure spring 5-2 is provided in the circular groove 5-1, and the output end of the pressure spring 5-2 is connected to a clamping frame 5-3. The clamping frame 5-3 is movably fitted on the outside of the column 3. Several anti-slip protrusions 5-4 are provided on the surface of the clamping frame 5-3, and the lower end face of the anti-slip protrusions 5-4 has an inclined transition structure.

[0048] In some examples, to achieve adjustable clamping connections for different workpieces, ensuring a stable connection and adaptability to various working scenarios, a clamping assembly 5 is designed. In terms of specific structure, several circular grooves 5-1 are evenly distributed on the side end face of the column 3. The depth, diameter, and other parameters of these circular grooves 5-1 are precisely calculated and designed to ensure that the pressure springs 5-2 can be placed tightly and stably within them. Each circular groove 5-1 is equipped with a pressure spring 5-2. The pressure springs 5-2 are made of high-elasticity, high-strength alloy material and undergo a special heat treatment process to give them good elasticity and a long service life. One end of the pressure spring 5-2 is firmly fixed to the bottom of the circular groove 5-1, and the other end is connected to the clamping frame 5-3. The clamping frame 5-3 is movably fitted onto the outside of the column 3, and its inner diameter matches the outer diameter of the column 3. This ensures that the clamping frame 5-3 can move flexibly on the column 3 and also ensures the fitting accuracy between the two, preventing shaking or displacement.

[0049] In its natural state, the pressure spring 5-2 generates an outward elastic force. This elastic force acts on the clamping frame 5-3, causing it to exert pressure on the surrounding workpieces. When the device needs to be clamped onto the winding equipment, this pressure allows the clamping frame 5-3 to be firmly fitted onto the winding equipment and maintain a tight connection during the rotation of the winding equipment, without any loosening or falling off. Even when the winding equipment is rotating at high speed or subjected to a certain external impact, the elastic force of the pressure spring 5-2 can ensure that the clamping frame 5-3 is tightly attached to the surface of the winding equipment, achieving stable rotation.

[0050] To further enhance the clamping effect, several anti-slip protrusions 5-4 are provided on the surface of the clamping frame 5-3. These anti-slip protrusions 5-4 are tightly integrated with the clamping frame 5-3. The lower end face of the anti-slip protrusion 5-4 is designed with an inclined transition structure, which increases the contact area between the anti-slip protrusion 5-4 and the workpiece surface, enabling it to produce a better anti-slip effect when in contact with the workpiece. When the clamping frame 5-3 clamps the workpiece, the anti-slip protrusions 5-4 are in close contact with the workpiece surface, increasing the friction between the two and effectively preventing the clamping frame 5-3 from sliding on the workpiece surface, further improving the stability of the clamping. The anti-slip protrusions 5-4 can all play their anti-slip role, ensuring a more reliable connection between the clamping frame 5-3 and the workpiece.

[0051] For example, such as Figure 4 As shown, the clamping frame 5-3 has an overall U-shaped structure, and the surface of the clamping frame 5-3 located at the anti-slip convex layer 5-4 is a concave structure surface.

[0052] In some examples, a U-shaped structure is used to fit the clamping frame 5-3 onto the outside of the column 3, allowing the clamping frame 5-3 to move while maintaining a constant angle.

[0053] For example, such as Figure 2As shown, a sliding plate 6 is provided on the lower end face of the clamping frame 5-3, and the sliding plate 6 is fixed at an inclined angle.

[0054] In some examples, by providing a slide plate 6, the winding device can slide in and smoothly open the clamping frames 5-3 upon insertion.

[0055] For example, such as Figure 3 As shown, the anti-slip raised layer 5-4 is made of hard rubber.

[0056] In some examples, a rigid rubber material structure can increase the anti-slip effect, allowing the wire spool to remain rotating with the winding equipment without slipping.

[0057] For example, such as Figure 1 As shown, the grooves 4-1 are distributed in a cross shape with opposite points.

[0058] In some examples, a cross-shaped distribution of points provides relatively more stable support.

[0059] For example, such as Figure 5 As shown, the outer end face of support block 4-5 is an arc-shaped structural surface.

[0060] In some examples, the curved structural surface makes the support block 4-5 fit more closely to the surface of the welding wire spool body 1, resulting in a better firmness.

[0061] When installing the inner support shell 2 to the welding wire spool body 1, align the locking block 4-2 on the side surface of the inner support shell 2 with the groove 4-1 on the top of the welding wire spool body 1, and then insert it to stably install the inner support shell 2 inside the welding wire spool body 1. Rotate the stud 4-6 on the top of the inner support shell 2. The stud 4-6 will move up and down during rotation, driving the lower push block 4-7 to move downward. The push block 4-7 pushes the support block 4-5 on the inner post 4-4 to move outward, supporting the inner support shell 1. When the shaft of the winding equipment is inserted, it slides along the inclined surface of the slide plate 6, smoothly opening the clamping frame 5-3. The pressure spring 5-2 in the circular groove 5-1 on the side end face of the column 3 is compressed. When the shaft of the winding equipment is in place, the elastic force of the pressure spring 5-2 pushes the clamping frame 5-3, making it tightly fitted on the shaft of the winding equipment. During the winding process, the anti-slip convex layer 5-4 made of hard rubber can effectively prevent slippage between the welding wire spool and the winding equipment, ensuring that the welding wire spool rotates stably with the winding equipment.
