[0030] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0032] Spiral filter elements are widely used in various industrial fields, including oil and gas transportation, agricultural irrigation, medical equipment, aerospace and navigation, chemical production, and food processing. These fields place extremely stringent performance requirements on spiral filter elements, especially when used for long periods of time, under high intensity, and in corrosive environments. These requirements place extremely high standards on the filter element's strength, corrosion resistance, filtration accuracy, and durability. To meet these requirements, the filter element's structural design and manufacturing process must ensure high strength and precision, especially in terms of pressure resistance, corrosion resistance, and long-term operation. Spiral filter elements must exhibit excellent performance. As market demand continues to expand, the demand for high-performance spiral filter elements continues to grow.

[0033] Chinese patent application publication number CN117862279A discloses a rigid tube blank and its skeleton structure. The spiral filter element described in this application utilizes a welding process for its manufacturing. The primary manufacturing process involves spirally winding the filter membrane and supporting skeleton. After forming, the skeleton and filter membrane are secured by welding to ensure overall structural stability and forming stability. Prior art welding equipment typically includes a lead-out roller and a welding plate, which are used to weld the formed filter element.

[0034] However, the applicant discovered during actual production and use that, with the long-term use of the auxiliary components, maintenance issues gradually became apparent. Specifically, the removal of the auxiliary components presented significant difficulties, primarily due to the need to pay close attention to the direction of removal. Because one side of the auxiliary component abuts the channel of the spiral filter element, any careless operation during removal could result in the incorrect removal of the auxiliary component, thereby affecting the channel position of the spiral filter element.

[0035] Specifically, if the auxiliary parts accidentally come into contact with the spiral filter element's channel during disassembly, causing the spiral filter element's extraction path to shift, this could alter the spiral filter element's extraction position, affecting the weld quality between the frame and the filter membrane, and ultimately impacting the overall product performance and reliability. This issue not only complicates maintenance but can also reduce production efficiency, increasing production costs and potential losses.

[0036] Therefore, the technical problem mainly arises from insufficient consideration of the positional relationship between the auxiliary parts and the spiral filter element, as well as the lack of effective disassembly guidance and design improvements in actual operation.

[0037] Based on this, the present application provides a welding auxiliary adjustment mechanism and a welding device. The welding auxiliary adjustment mechanism is provided on the welding device. Figure 1The welding equipment includes a frame (not shown), a take-off roller 600, a conveyor belt 700, and a welding pad 800. The take-off roller 600 is rotatably mounted on the frame, the conveyor belt 700 is partially wound around the inlet end of the take-off roller 600, and the welding pad 800 is rotatably mounted on the frame at the outlet end of the take-off roller 600. After spiral winding, the filter membrane and the frame are wound onto the take-off roller 600 via the conveyor belt 700 and then moved out of the outlet end of the take-off roller 600 along the length of the take-off roller 600. At the same time, since the welding pad 800 is located near the outlet end of the take-off roller 600, during its rotation, part of its surface can rotate to be located in the moving path of the filter membrane and the frame, thereby forming a welding point. In this way, the mutually contacting portion of the filter membrane and the frame during spiral winding passes through the welding point, and the contacting portion of the two is continuously welded at the outlet end of the take-off roller 600 to achieve the final welded state.

[0038] Please refer to Figures 1 to 6 In some embodiments, the welding auxiliary adjustment mechanism includes a mounting frame 100, an adjustment base plate 200, and a mounting base 300. The mounting frame 100 is detachably mounted on the adjustment base plate 200 and is used to mount auxiliary components (not shown). It is worth noting that the mounting base 300 is mounted on a frame, but the frame is not shown in the figure.

[0039] Exemplarily, the auxiliary component is provided with a lead-out channel on the side facing away from the mounting frame 100, which is used to allow the filter element to spiral through. Furthermore, the connection 510 between the mounting frame 100 and the auxiliary component is located at the back of the lead-out channel, so that the connection between the mounting frame 100 and the auxiliary component does not affect the normal extraction of the spiral filter element. Exemplarily, the lead-out channel is formed between the lead-out roller 600 and the auxiliary component.

[0040] Meanwhile, the mounting base 300 is provided with a sliding groove 310. The length of the sliding groove 310 is perpendicular to the axis of the filter element and extends horizontally away from the filter element. Furthermore, the adjustment base 200 is provided with a positioning guide assembly 400. The positioning guide assembly 400 slidably engages with the sliding groove 310 and has a first state and a second state. Exemplarily, the first and second states can be switched by adjustment.

[0041] When the positioning guide assembly 400 is in the first state, the positioning guide assembly 400 can slide along the length direction of the sliding groove 310. When the positioning guide assembly 400 is in the second state, the positioning guide assembly 400 is locked in the current position in the sliding groove 310.

[0042] On this basis, the sliding groove 310 on the mounting base 300 is perpendicular to the axis of the filter element and extends horizontally away from the filter element, ensuring that the positioning guide assembly 400 can slide freely within the sliding groove 310, facilitating adjustment of its position. Furthermore, when the auxiliary component needs to be removed, the positioning guide assembly 400 can be moved away from the spiral filter element, that is, along the length of the sliding groove 310, away from the spiral filter element. This allows the positioning guide assembly 400 to move the auxiliary component along the length of the sliding groove 310, away from the spiral filter element. In this case, when the auxiliary component is removed, its removal orientation is toward the side of the extraction channel away from the spiral filter element. Therefore, the removal of the auxiliary component will not affect the original extraction path of the spiral filter element. That is, the auxiliary component will not contact the extraction roller 600 during removal, thus preventing the auxiliary component from contacting the extraction roller 600 during removal, thereby preventing the position of the extraction roller 600 from shifting. In summary, with such an arrangement, the auxiliary parts can be disassembled more conveniently, and the positions of other parts in the welding device are not easily affected during maintenance, which is beneficial to improving the convenience of maintaining the welding device.

[0043] In some embodiments, reference Figure 3 、 Figure 4 The positioning guide assembly 400 includes a sliding member 410 and a locking member 420. The sliding member 410 is installed on the adjustment base plate 200, and the sliding member 410 slides with the sliding groove 310. The locking member 420 is detachably connected between the sliding member 410 and the mounting base 300.

[0044] At the same time, when the locking member 420 is disconnected from the sliding member 410, the sliding member 410 can slide directionally along the length of the sliding groove 310, so that the positioning guide assembly 400 is in the first state. When the locking member 420 remains connected to the sliding member 410 and the mounting base 300, the movement of the sliding member 410 along the length of the sliding groove 310 is restricted, so that the positioning guide assembly 400 is in the second state.

[0045] Furthermore, the design of sliding member 410 allows it to slide freely when locking member 420 is disconnected, significantly facilitating user convenience. When auxiliary components require adjustment or maintenance, the user simply releases locking member 420, allowing sliding member 410 to freely move along the length of sliding slot 310. This flexibility allows operators to quickly adapt to varying welding requirements and ensures precise positioning during the welding process. Particularly in complex production environments, where the actual operating state of the filter element may vary depending on the specific process requirements, the free sliding of sliding member 410 effectively reduces operational inconveniences caused by the fixed structure.

[0046] Secondly, when the locking member 420 remains connected to the sliding member 410 and the mounting base 300, the movement of the sliding member 410 is restricted, locking the positioning guide assembly 400 and ensuring that the assembly's position remains stable during the welding process. This design is crucial to welding accuracy, as any slight movement can affect the weld and, in turn, the quality of the final product. Through this locking mechanism, the system can resist external interference, providing a more reliable welding environment.

[0047] Furthermore, the removable connection between the sliding member 410 and the locking member 420 not only improves the system's adaptability but also simplifies maintenance. When the positioning guide assembly 400 needs to be replaced or repaired, the user can easily remove the locking member 420 and make appropriate adjustments without disturbing the entire welding equipment structure. This design approach not only ensures safety but also improves maintenance efficiency and reduces the risk of production downtime caused by equipment failure.

[0048] In some embodiments, reference Figure 3 、 Figure 4 The sliding member 410 includes a stopper 411 and a sliding portion 412. The adjustment base plate 200 is provided with a through-hole that plugs into the sliding portion 412. The sliding portion 412 extends downward through the through-hole into the sliding groove 310. The stopper 411 is provided at the upper end of the sliding portion 412 and engages with the upper surface of the adjustment base plate 200.

[0049] Exemplarily, the locking member 420 includes a screw 421 and a nut 422. A thread groove 4121 is provided at the lower end of the sliding portion 412, and the screw 421 is threadedly engaged with the thread groove 4121. Furthermore, the length direction of the thread groove 4121 is consistent with the length direction of the sliding portion 412. The nut 422 is provided at the end of the screw 421 away from the thread groove 4121, and the outer diameter of the nut 422 is greater than the width of the sliding groove 310. Exemplarily, the sliding groove 310 is a waist-shaped hole, and the contour of the sliding groove 310 near its own end matches the outer periphery of the sliding portion 412. This prevents the sliding portion 412 from being scratched and damaged when it slides to the end of the sliding groove 310.

[0050] With this arrangement, when the sliding member 410 needs to be locked in the sliding groove 310, the screw rod 421 is directly rotated, causing the screw rod 421 to move inward along the length of the thread groove 4121. This allows the nut 422 on the screw rod 421 to gradually approach the outer surface of the adjustment base plate 200. Because the outer diameter of the nut 422 is greater than the width of the sliding groove 310, the nut 422 directly abuts the outer surface of the adjustment base plate 200 and does not enter the sliding groove. At this time, the friction resistance generated by the abutment between the nut 422 and the outer surface of the adjustment base plate 200 limits the further movement of the sliding portion 412 in the sliding groove 310. Combined with the coordinated abutment of the limit portion 411 on the other surface of the adjustment base plate 200, the sliding member 410 is locked. Similarly, when it is necessary to contact the locked state of the sliding member 410 and the sliding groove 310, the screw 421 is directly rotated in the opposite direction again, so that the screw 421 gradually disengages from the thread groove 4121, and then the nut 422 is moved away from the outer surface of the adjustment base plate 200. In this way, the sliding part 412 can be contacted and locked, so that the sliding part 412 can move normally along the length direction of the sliding groove.

[0051] In some embodiments, combined with Figure 2 、 Figure 5 The mounting frame 100 includes a clamping post 110, one end of which includes a clamping portion 111. The adjustable base plate 200 is provided with a clamping slot 210 that engages with the clamping portion 111. For example, the clamping slot 210 extends perpendicularly to the length of the sliding slot 310 in a horizontal plane, and the cross-section of the clamping slot 210 is dovetail-shaped or T-shaped. Furthermore, the sliding entrance of the clamping slot 210 faces a side perpendicular to the sliding direction of the adjustable base plate 200. This allows the clamping portion 111 to slide into the clamping slot 210 from a side perpendicular to the sliding direction of the adjustable base plate 200. Simultaneously, the inner sidewalls of the clamping slot 210 limit the clamping portion 111, ensuring that the clamping portion 111 remains stably within the clamping slot 210 during movement of the adjustable base plate 200, thereby improving the connection stability between the clamping post 110 and the adjustable base plate 200 during movement.

[0052] In some embodiments, Figure 2 、 5 As shown, at least two groups of clamping posts 110 are provided in parallel on the mounting frame 100 , and a connecting piece 500 is provided between two adjacent clamping posts 110 . The connecting piece 500 is used to connect the two adjacent clamping posts 110 to confine the clamping posts 110 in the clamping slot 210 .

[0053] Exemplarily, the connector 500 includes a connecting portion 510 and a connecting bolt 520. The connecting portion 510 is located between two adjacent clamping posts 110. Furthermore, the length of the connecting portion 510 is horizontally perpendicular to the direction of movement of the adjustment base 200. A first screw hole 511 is defined through the connecting portion 510 along its axial direction, and a second screw hole 112 is defined through the clamping posts 110. The connecting bolt 520 is threadedly inserted into both the first and second screw holes 511 and 112.

[0054] With such a configuration, after the connecting bolt 520 is passed through the second screw hole 112 and the first screw hole 511 in sequence, the connecting part 510 and the clamping column 110 can be stably connected, and then the two clamping columns 110 can be simultaneously restricted in the clamping groove 210, so that the clamping column 110 can be more stably located in the clamping groove 210, thereby improving the connection stability between the clamping column 110 and the adjustment substrate 200.

[0055] In some embodiments, combined Figure 2 The mounting frame 100 further includes a mounting portion 120, which is located above the clamping post 110 and is used to provide a mounting location for an auxiliary component. For example, the mounting location is located on the side of the mounting portion 120 facing away from the adjustment base plate 200. The mounting location formed by the mounting portion 120 allows the auxiliary component to be mounted on the side facing away from the adjustment base plate 200 and close to the lead-out roller 600.

[0056] In some embodiments, combined Figure 5 、 Figure 6 The mounting base 300 is provided with a rolling groove 320, the length of which is consistent with the length of the sliding groove 310. Multiple sets of rolling pulleys 330 are provided along the length of the rolling groove 320. The adjustment base 200 has a rolling contact surface 220, and the rolling pulleys 330 roll in engagement with the rolling contact surface 220. For example, a vertical rod is vertically provided on the mounting base 300, and the rolling pulleys 330 are slidably and rotatably disposed on top of the vertical rod. That is, the rolling surface of the rolling pulleys 330 is horizontal, while the rolling contact surface 220 of the adjustment base 200 is vertical. This configuration allows the adjustment base 200 to move more smoothly, thereby reducing frictional resistance during movement of the adjustment base 200.

[0057] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
