Description

Technical Field

[0001] This invention relates to the field of filter element metal frame welding technology, and more specifically to a welding equipment for the metal frame of a melt filter element. Background Technology

[0002] Melt filters are indispensable key equipment in industries such as chemical fiber, plastics, and petrochemicals. They are widely used in the impurity filtration stage of melt production processes such as polyester, PBT, and recycled plastics. Because melt filters operate under high temperature (up to 300℃) and high pressure (up to 40MPa) conditions for a long time, their design conditions and manufacturing process requirements are extremely stringent. As the core component of melt filters, the performance and quality of the filter element are directly related to the quality of the final product.

[0003] Melt filter cartridges typically consist of a metal frame and a filter medium covering the frame. The metal frame generally consists of a cylindrical wire mesh and end caps welded to both ends. To ensure the long-term stable operation of the filter cartridge under high temperature and high pressure conditions, the quality of the circumferential weld between the end caps and the cylindrical wire mesh is crucial. However, in current methods, the cylindrical wire mesh and the end caps are typically welded manually. When welding by visually approximating the position, the relative positional accuracy between the end caps and the cylindrical wire mesh cannot be guaranteed, and the perpendicularity between the end cap face and the wire mesh axis is also difficult to reliably ensure. Since the wire mesh itself is a thin-walled metal wire mesh structure with poor rigidity, it is prone to radial displacement and ellipticity changes due to thermal stress and human vibration during welding, resulting in poor concentricity between the end caps and the wire mesh. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal skeleton welding device for melt filter cartridges, so as to solve the problem in the background art that manual welding of cylindrical wire mesh and its end caps at both ends cannot guarantee the relative positional accuracy between the end caps and the cylindrical wire mesh.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-13 The present invention provides a metal skeleton welding equipment for a melt filter element, including a workbench 1 and a workbench 2. The workbench 1 is higher than the workbench 2, and the workbench 1 and the workbench 2 are arranged in a stepped manner. The upper surface of the workbench 2 is provided with a welding component 3 for welding the metal skeleton body 9. The equipment also includes a table surface 4, an inner support component 5, a scaling drive component 6, an outer wrapping component 7, and a conical end mounting component 8. Welding component 3 is driven by a ball screw linear module to move the welding robot arm laterally along the worktable. The base of the ball screw linear module is fixedly connected to the upper surface of the worktable 2 by bolts. The ball screw linear module is arranged along the length of the worktable 2 and its position corresponds to the position of the circumferential seam to be welded on the metal frame body 9. The mounting base of the welding robot arm is fixedly connected to the upper surface of the slider of the transverse module by bolts. A welding gun is installed at the free end of the welding robot arm.

[0033] The metal frame body 9 consists of three parts: a cylindrical filter screen 901, a front cover 902, and a rear cover 903. During welding, the front cover 902 is at one end of the cylindrical filter screen 901, and the rear cover 903 is at the other end of the cylindrical filter screen 901. The internal support 5 provides internal support, and the external wrapping 7 limits external positioning. The welding is completed in conjunction with the welding component 3.

[0034] like Figures 1 to 2 As shown, the tabletop 4 is fixedly connected to the upper surface of the workbench 1 near one end by bolts, serving as the installation base; like Figures 3 to 7 As shown, the inner support 5 is installed on the upper surface of the table 4 and is used to provide multi-point support for the inside of the cylindrical filter screen 901 in a ring shape. The inner support 5 includes a fixed tube 501, an intermediate tube 502 and a core rod 503. The fixed tube 501 is installed on the table 4 by a clamp. The end of the fixed tube 501 extends horizontally towards the middle of the workbench 1. The intermediate tube 502 is slidably installed inside the fixed tube 501. The core rod 503 is slidably installed inside the intermediate tube 502. The fixed tube 501, the intermediate tube 502 and the core rod 503 form a three-stage sleeve structure.

[0035] The outer circumferential wall of the fixed tube 501 is provided with an annular recess 505 and a side notch 506. The annular recess 505 is annularly recessed along the circumferential direction of the fixed tube 501, and the side notch 506 is opened in the circumference of the annular recess 505 and along the length direction of the annular recess 505, providing clearance space for the movement of the intermediate tube 502 and the core rod 503.

[0036] The outer circumferential wall of the fixed tube 501 is also detachably fitted with a threaded mounting sleeve 504 by bolts. The threaded mounting sleeve 504 is used to fix the front end cover 902. The first garland seat 5022 and the second garland seat 5032 are slidably installed outside the annular recess 505. The inner side notches 506 of the first garland seat 5022 and the second garland seat 5032 are respectively fixed to the ends of the intermediate tube 502 and the core rod 503. The other ends of the intermediate tube 502 and the core rod 503 are respectively fixedly connected to the end block 5021 and the second end block 5031 by bolts. The first garland seat 5022 and the second garland seat 5032 are both in the form of a multi-notch annular structure.

[0037] The folding inner support 507 is the core actuator for achieving multi-point support. Multiple folding inner supports 507 are arranged in a ring array and installed in the annular notches on the outer circumference of the wreath seat 1 5022 and the wreath seat 2 5032. Each folding inner support 507 includes two diagonal support rods 5071 and one horizontal support rod 5072. One end of each of the two diagonal support rods 5071 is rotatably installed in the annular notches of the wreath seat 1 5022 and the wreath seat 2 5032, and the diagonal support rods 5071 on the wreath seat 1 5022 and the wreath seat 2 5032 correspond one-to-one. A horizontal support rod 5072 is rotatably installed between the top ends of each pair of corresponding diagonal support rods 5071. The relative movement of the wreath seat 1 5022 and the wreath seat 2 5032 causes the folding inner support 507 to fold or lift.

[0038] When the first wreath seat 5022 and the second wreath seat 5032 move closer to each other along the annular recess 505, the angle between the diagonal support rod 5071 and the horizontal support rod 5072 increases, and the horizontal support rod 5072 extends radially outward, tightening the inner wall of the cylindrical filter screen 901; conversely, when the first wreath seat 5022 and the second wreath seat 5032 move further apart, the horizontal support rod 5072 retracts radially inward, loosening the cylindrical filter screen 901. When the inner support 507 is fully folded, it is stored in the annular notch on the outer circumference of the first wreath seat 5022 and the second wreath seat 5032. The diameter of the first wreath seat 5022 and the second wreath seat 5032 is smaller than the diameter of the fixed tube 501, which facilitates the removal of the metal skeleton body 9 and realizes multi-point uniform support from inside the cylindrical filter screen 901.

[0039] To enable the folding and unfolding of the inner support 507 and the synchronous lateral movement and relative sliding of the intermediate tube 502 and the core rod 503, a scaling drive 6 is provided on the upper surface of the platform 4, such as... Figure 8 and Figure 9As shown, the scaling drive unit 6 includes a rack frame 601, a rack frame 602, a guide rod frame 603, a slide block 604, a mounting base 605, a drive motor 606, a gear 607, and a ball screw linear module 608. Rack frame 1 601 is fixedly connected to the upper surface of end block 1 5021 by bolts, and rack frame 2 602 is fixedly connected to the lower surface of end block 2 5031 by bolts. The rack parts of rack frame 1 601 and rack frame 2 602 are arranged parallel to each other and the tooth surfaces are opposite each other. Rack frame 1 601 and rack frame 2 602 together form a rack assembly, which cooperates with gear 607 to achieve bidirectional drive.

[0040] The slide 604 is located above the table 4 and below the rack carrier 602. The mounting base 605 is fixedly connected to the upper surface of the slide 604 by bolts. The drive motor 606 is fixedly connected to one side of the mounting base 605 by bolts. The output shaft of the drive motor 606 passes through the mounting base 605. The gear 607 is keyed to the output end of the drive motor 606. The gear 607 meshes with the tooth surfaces of both the rack carrier 601 and the rack carrier 602.

[0041] The drive motor 606 is a servo motor with an encoder. The number of rotations and rotation angle of the output shaft of the drive motor 606 are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0042] Two rod holders 603 are arranged in parallel and fixed to the upper surface of the table 4 by bolts. The two rod holders 603 pass through the two ends of the slide block 604 respectively. The slide block 604 is slidably connected to the rod holders 603 through a sliding sleeve, which provides guidance for the movement of the slide block 604.

[0043] The ball screw linear module 608 is fixedly connected to the upper surface of the platform 4 by bolts. A connecting bracket 609 is fixedly connected to the upper surface of its slider by bolts, and the other end of the connecting bracket 609 is fixed to one end of the slide block 604. The ball screw linear module 608 is used to drive the entire slide block 604 to move along the length of the guide rod frame 603.

[0044] When the folding inner support 507 needs to be unfolded, the drive motor 606 starts, driving the gear 607 to rotate. Since the gear 607 meshes with both rack frame one 601 and rack frame two 602 at the same time, and their tooth surfaces are opposite each other, the rotation of the gear 607 drives rack frame one 601 and rack frame two 602 to move in opposite directions. Specifically, rack frame one 601 drives end block one 5021, wreath seat one 5022 and intermediate tube 502 to move in one direction, while rack frame two 602 drives end block two 5031, wreath seat two 5032 and core rod 503 to move in opposite directions. Wreath seat one 5022 and wreath seat two 5032 move away from each other, and the folding inner support 507 unfolds.

[0045] When the support position needs to be adjusted laterally, the ball screw linear module 608 drives the slide 604 to move along the length of the smooth rod frame 603 through the connecting frame 609, which drives the entire rack assembly and the drive motor 606 to move laterally synchronously, thereby realizing the axial positioning adjustment of the inner support 5.

[0046] like Figure 10 and Figure 11 As shown, the outer wrapping component 7 is installed in the middle of the upper surface of the workbench 1 to wrap the cylindrical filter screen 901 in a ring-like manner. The outer wrapping component 7 works in conjunction with the inner support component 5 to limit the outer part while supporting the inner part, preventing the cylindrical filter screen 901 from deforming due to excessive force. The outer wrapping component 7 includes a bearing seat 701, two vertical frames 702, two outer arc plates 704, and a transverse drive part 707. The support seat 701 is mounted on the workbench 1 via the transverse drive unit 707. Two vertical frames 702 are respectively fixedly connected to both ends of the upper surface of the support seat 701 by bolts. Electric push rods 703 are fixedly connected to the opposite sides of the two vertical frames 702 by bolts. Two outer arc plates 704 are arranged opposite each other. The center of the outer arc of the outer arc plate 704 is fixed to the telescopic end of the electric push rod 703. Each outer arc plate 704 is also fixedly connected to multiple guide rods 705 by bolts. The other end of the guide rod 705 passes through the vertical frame 702 and is slidably connected to the vertical frame 702 through a sliding sleeve, providing guidance for the movement of the outer arc plate 704.

[0047] It should be noted that the electric push rod 703 in this application is a linear motion power actuator that converts electrical energy into mechanical energy. It can be connected to an external power supply and control switch and drive the push rod to perform linear reciprocating motion by controlling the forward and reverse rotation of the motor. It can be used in conjunction with limit switches or Hall sensors to achieve safety protection and position control of the push rod's extension and retraction stroke. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0048] like Figure 11 As shown, the transverse drive unit 707 includes two guide rails 7071 and a ball screw linear module 7072. The two guide rails 7071 are arranged in parallel and are fixedly connected to the lower surface of the table 4 by bolts. A clearance opening 706 is provided on the upper surface of the table 4 between the two guide rails 7071 to provide clearance space for the connection between the bearing seat 701 and the guide rail slider. The sliders of the two guide rails 7071 are respectively fixed to the lower surface of the bearing seat 701 by bolts. The ball screw linear module 7072 is fixedly connected to the surface of the table 4 by bolts and is located between two guide rails 7071. It is used to drive the bearing seat 701 to move laterally along the length of the guide rails 7071.

[0049] In use, the ball screw linear module 7072 drives the bearing seat 701 to move along the guide rail 7071, so that the two outer arc plates 704 are aligned with the outer wall of the cylindrical filter screen 901. Then, the two electric push rods 703 extend synchronously, pushing the two outer arc plates 704 to move towards each other, wrapping the cylindrical filter screen 901 from the outside. The guide rod 705 slides in the vertical frame 702 to ensure that the outer arc plates 704 move smoothly. After wrapping, a small gap is maintained between the inner wall of the outer arc plate 704 and the outer wall of the cylindrical filter screen 901, which serves as a limit and prevents the cylindrical filter screen 901 from deforming due to excessive compression.

[0050] like Figure 12 As shown, the conical end mounting component 8 is installed on the upper surface of the workbench 1 and is used to place the rear end cover 903. The conical end mounting component 8 includes a ball screw linear module 801, a connecting shaft 803, a conical plate 804, and a limiting ring 805. The ball screw linear module 3 801 is fixedly connected to the upper surface of the worktable 1 by bolts, and the right angle bracket 802 is fixedly connected to the upper surface of the slide of the ball screw linear module 3 801 by bolts. The connecting shaft 803 is fixedly connected to the side of the right angle bracket 802 facing the middle of the workbench 1 by bolts. The tapered plate 804 is fixedly connected to the free end of the connecting shaft 803 by bolts. The limiting ring 805 is integrally formed on the outer edge of the opening end of the tapered plate 804. The limiting ring 805 and the inside of the tapered plate 804 form a cavity to accommodate the rear end cover 903.

[0051] The rear end cover 903 is placed inside the tapered plate 804, and the limiting ring 805 circumferentially limits the rear end cover 903. The ball screw linear module 801 drives the right angle frame 802 to move as a whole, bringing the rear end cover 903 closer to the end of the cylindrical filter screen 901, thus completing the assembly and positioning.

[0052] It should be noted that all ball screw linear modules in this application achieve precise linear motion through the coordinated operation of various components: the slide table is the moving component, the ball screw and guide rail constitute the transmission core, the motor and coupling provide power, and the aluminum alloy profile and support base ensure structural stability. Furthermore, by cooperating with magnetic switches, proximity switches, or photoelectric switches, the displacement of the slide table can be precisely controlled. Those skilled in the art can set these parameters according to actual needs, which will not be elaborated here.

[0053] The working principle of the present invention is as follows: First, the front end cover 902 is fixed to one end of the fixed tube 501 by the threaded mounting sleeve 504. Then, the cylindrical filter screen 901 is fitted onto the outside of the folded inner support 507 of the inner support member 5, so that the front end cover 902 is connected to one end of the cylindrical filter screen 901. Start the drive motor 606, and the gear 607 drives the rack frame 1 601 and rack frame 2 602 to move relative to each other, causing the wreath seat 1 5022 and wreath seat 2 5032 to move away from each other. The folding inner support 507 unfolds, and the horizontal support rod 5072 supports the front edge of the cylindrical filter screen 901 from multiple points inside. The ball screw linear module 7072 drives the bearing seat 701 to move to the working position. The two electric push rods 703 extend synchronously, pushing the two outer arc plates 704 to wrap around the cylindrical filter screen 901 from the outside. Together with the internal support, they prevent deformation. Then, the welding component 3 performs the first welding on the gap between the cylindrical filter screen 901 and the front cover 902. After the first welding is completed, the outer wrapping 7 remains stationary, the inner support 5 retracts, the drive motor 606 is started, the gear 607 drives the rack frame 1 601 and rack frame 2 602 to move in opposite directions, causing the garland seat 1 5022 and garland seat 2 5032 to move closer to each other, the inner support 507 is folded, the cross support rod 5072 is disengaged from the cylindrical filter screen 901, and then the ball screw linear module 1 608 is started to drive the entire inner support 5 to move laterally, and then to the rear end of the cylindrical filter screen 901 to reopen and internally pre-position and support the rear edge of the cylindrical filter screen 901 at multiple points. Subsequently, the outer wrapping component 7 moves, and the ball screw linear module 2 7072 drives the bearing seat 701 to move along the guide rail 7071, so that the two outer arc plates 704 are aligned with the outer wall of the rear end of the cylindrical filter screen 901, and wrap the rear end of the cylindrical filter screen 901 from the outside. Then the inner support component 5 internally supports and tightens the rear end of the cylindrical filter screen 901 at multiple points. After the rear end of the cylindrical filter screen 901 is tightened, the rear end cover 903 is placed in the cavity of the conical plate 804.
