Description

Technical Field

[0001] The invention relates to the technical field of vibration screen mesh welding, and in particular to a welding device for vibration screen mesh processing. Background Art

[0002] The welding device for vibrating screen mesh processing is a device specially used for welding vibrating screen mesh, which plays a vital role in the process of screen mesh manufacturing and maintenance.

[0003] In the processing of vibrating screen mesh, rolling welding is a commonly used welding device and technology. The principle of rolling welding is to use the rolling effect of the rolling wheel to press the screen materials to be welded together tightly, and melt the welding wire through the high-temperature arc generated by the welding gun, so as to achieve the welding of the screen mesh. After searching, the patent with the announcement number CN115070318B discloses an adjustable circular screen welding device, including a frame, a slide, a telescopic structure, an auxiliary plate, a driving component and a welding structure, wherein the frame has a horizontally arranged guide rail, the slide is arranged on the guide rail along the slide, a rotating seat is arranged on the slide, the telescopic structure drives the slide to slide, and the auxiliary plate drives the slide to slide. The auxiliary plate is horizontally arranged above the slide table and is detachably connected to the rotating seat. The top of the auxiliary plate is provided with a receiving groove. The driving assembly is arranged on the frame and is dynamically connected to the rotating seat to drive the rotating seat to rotate. The welding structure is arranged on the frame and located above the auxiliary plate, and is used to weld each circular mesh to be welded in the receiving groove during the rotation of the auxiliary plate. The adjustable circular screen welding device provided by the above scheme changes the manual welding method, realizes the automatic welding of the circular screen, and can ensure the welding quality, improve the welding efficiency, and has strong adaptability and practicality. However, the above scheme still has the following shortcomings when it is actually used:

[0004] During the roll welding of the circular screen by the above-mentioned scheme, the device lacks the flattening treatment for the screen, which makes it difficult for the screen to be in a flat state. During the welding process, the uneven screen is prone to form low-lying areas, which are prone to accumulate particulate matter. Over time, these particulate matter may gradually clog the screen and reduce the screening efficiency. In addition, the uneven screen may cause the liquid to form high-speed flow in sharp or raised parts during the filtration process. This high-speed flow will accelerate the wear of the screen and shorten its service life. At the same time, the uneven screen is also more difficult to clean and maintain.

[0005] Therefore, it is necessary to design a welding device for vibrating screen mesh processing to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0064] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0065] Reference Figure 1 , 2 , 4, 5, 6 and Fig. 9 A welding device for processing a vibrating screen mesh comprises a frame 1, on which a circular metal welding plate is arranged; a vertical rod 2, fixed to the top surface of the frame 1; a lifting seat 3, which is escalably arranged on the vertical rod 2; and a mounting seat 4, which is fixed to an end of the lifting seat 3 away from the vertical rod 2;

[0066] The vibration screen mesh processing welding device also includes a rolling welding structure, which is arranged on the mounting seat 4. The rolling welding structure includes a rolling welding module 55. The rolling welding structure also includes: a bracket 51 (such as Figure 5 As shown), fixed on the side of the mounting seat 4; the servo motor 52 is mounted on the bracket 51; the rotating seat 53 is rotatably mounted on the mounting seat 4, the rotating seat 53 is fixedly connected to the end of the output shaft of the servo motor 52, and the rotating seat 53 is a columnar structure; the mounting rod 54, one end of the mounting rod 54 is fixedly connected to the outer peripheral surface of the rotating seat 53, and the other end of the mounting rod 54 is fixedly connected to the roll welding module 55;

[0067] The welding device for processing the vibrating screen mesh also includes a flattening structure, which is arranged on the mounting seat 4. The flattening structure is arranged opposite to the metal welding plate. The flattening structure includes: an outer cylinder 61, which is fixed to the bottom surface of the mounting seat 4, and the bottom end of the outer cylinder 61 is open; an inner rod 62 (such as Figure 6 As shown, the inner rod 62 is slidably disposed in the outer cylinder 61, and the bottom end of the inner rod 62 extends to the outside of the outer cylinder 61; the booster spring 63 (as shown Fig.10As shown in the figure, one end of the booster spring 63 is connected to the inner top surface of the outer cylinder 61, and the other end of the booster spring 63 is connected to the inner rod 62; the flattening plate 64 is fixed to one end of the inner rod 62 located outside the outer cylinder 61. When the flattening plate 64 presses the screen, the flattening plate 64 and the inner rod 62 cannot move, and the lifting seat 3 will continue to move downward. At this time, the inner rod 62 will be inserted into the outer cylinder 61 and squeeze the booster spring 63. At the same time, the roll welding module 55 continues to move downward until the roll welding wheel on the roll welding module 55 presses the edge of the screen. Further, the servo motor 52 is turned on to drive the rotating seat 53 to rotate. During the rotation of the roll welding module 55, the roll welding wheel on it cooperates with the metal welding plate to roll weld the screen; four flattening members are all arranged on the outer cylinder 61, and the flattening members include: a rotating ring 71 (as shown in the figure Figure 6 As shown in the figure, the rotating sleeve is arranged on the outer cylinder 61, the output shaft of the servo motor 52, the outer cylinder 61, the inner rod 62, the flattening disk 64 and the four rotating rings 71 are arranged along the same axis; the flattening plate 72 is placed on the side of the flattening disk 64, the flattening plate 72 is located above the metal welding disk, the bottom surface of the flattening plate 72 and the bottom surface of the flattening disk 64 are located on the same plane, and the four flattening plates 72 are arranged in a circumferential array around the outer cylinder 61, each flattening plate 72 is fixed with a fixed magnetic sheet 74, and the outer peripheral surface of the flattening disk 64 is fixed with four positioning magnetic sheets 75, and the four fixed magnetic sheets 74 are respectively adsorbed on the four positioning magnetic sheets 75. When the screen is placed on the metal welding disk, the staff controls the lifting seat 3 to move downward, and the lifting seat 3 can drive the installation when it moves downward. As the mounting seat 4 moves downward, the rolling welding structure and the flattening structure will move downward accordingly. In this process, the flattening plate 64 and the four flattening plates 72 first contact the screen, and the flattening plate 64 can press the middle position of the screen, and the four flattening plates 72 can flatten the outer edge position of the screen. The flattening plate 64 and the four flattening plates 72 work together to flatten the screen and keep the screen in a flat state. This design can avoid the presence of concave and convex areas in the screen after welding, and can maintain the flatness of the screen; the connecting rod 73 has an L-shaped structure, one end of the connecting rod 73 is fixedly connected to the outer peripheral surface of the rotating ring 71, and the other end of the connecting rod 73 is fixedly connected to the top surface of the flattening plate 72; the slot 76 (such as Fig.10 As shown in the figure), the bottom surface of the pressing plate 72 is provided, and the slot 76 is arranged opposite to the outer edge of the metal welding plate. The arrangement of the slot 76 can prevent the bottom surface of the pressing plate 72 from contacting the welding position of the screen, and prevent the friction loss of the welding position of the screen when the pressing plate 72 rotates, thereby preventing the pressing plate 72 from affecting the welding effect of the device on the screen;

[0068] The vibration screen mesh processing welding device also includes a push structure, which is arranged on the roll welding module 55, and the push structure includes: a cross bar 81 (such as Figure 4As shown in the figure, one end of the cross bar 81 is fixed to the housing of the roll welding module 55; a push rod 82 is fixed to the end of the cross bar 81 away from the roll welding module 55, and the push rod 82 is arranged in the vertical direction; a ball 83 is rotatably arranged at the bottom end of the push rod 82, and the push rod 82 is located in the forward direction of the roll welding module 55. Before the roll welding wheel in the roll welding module 55 contacts the screen, the ball 83 on the push rod 82 will first contact the screen. In this case, the push rod 82 will rotate along the outer edge of the screen. The push rod 82 contacts one of the pressure plates 72 and pushes it to rotate. The four pressure plates 72 gather together under the push of the push rod 82 and rotate synchronously under the push of the push rod 82 until the rolling welding wheels in the rolling welding module 55 travel a circle along the outer edge of the screen. By setting the push rod 82, it is possible to prevent the rolling welding wheels in the rolling welding module 55 from contacting the pressure plate 72 during the movement, thereby preventing the pressure plate 72 from causing adverse effects on the welding of the rolling welding module 55, thereby ensuring the welding effect of the rolling welding module 55 on the screen.

[0069] When the vibration screen mesh processing welding device proposed by the present invention is used, in the initial state, the flattening plate 64 and the four flattening plates 72 are all located directly above the metal welding plate, and the four flattening plates 72 are distributed in a circumferential array around the outer cylinder 61. At this time, the four fixed magnetic sheets 74 on the four flattening plates 72 are respectively adsorbed on the four positioning magnetic sheets 75. When welding the screen mesh, the staff first stacks the multiple layers of screen mesh together and places them on the metal welding plate. The metal welding plate is provided with a positioning member for positioning the screen mesh. The role of the positioning member is to ensure that the screen mesh and the metal welding plate are in a coaxial state. The specific structure and positioning principle of the positioning member are conventional means, which are not shown in the figure and will not be described in detail here.

[0070] When the screen is placed on the metal welding plate, the staff controls the lifting seat 3 to move downward. When the lifting seat 3 moves downward, it can drive the mounting seat 4 to move downward. When the mounting seat 4 moves downward, the rolling welding structure and the flattening structure will move downward accordingly. In this process, the flattening plate 64 and the four flattening plates 72 first contact the screen, and the flattening plate 64 can press the middle position of the screen, and the four flattening plates 72 can flatten the outer edge position of the screen. The flattening plate 64 and the four flattening plates 72 jointly flatten the screen to keep the screen in a flat state. This design can avoid the presence of concave and convex areas in the screen after welding, and can maintain the flatness of the screen. It is worth mentioning that when the flattening plate 72 presses the screen, the end of the flattening plate 72 away from the flattening plate 64 is just aligned with the outer edge position of the screen, which enables the four circumferentially arrayed flattening plates 72 to comprehensively flatten the screen, which can ensure the flattening effect of the screen, and thus ensure the flatness of the screen during the welding process.

[0071] When the flattening plate 64 and the four flattening plates 72 press the screen, the flattening plate 64 and the inner rod 62 cannot move, and the lifting seat 3 will continue to move downward. At this time, the inner rod 62 will be inserted into the outer cylinder 61 and squeeze the booster spring 63. At the same time, the roll welding module 55 continues to move downward until the roll welding wheel on the roll welding module 55 presses the edge of the screen. When the roll welding wheel presses the edge of the screen, the ball 83 in the pushing structure will also come into contact with the screen. Further, the servo motor 52 runs to drive the rotating seat 53 to rotate. When the rotating seat 53 rotates, it can drive the roll welding module 55 to rotate around the outer cylinder 61 through the mounting rod 54. The roll welding module 55 rotates. During the process, the rolling welding wheel thereon cooperates with the metal welding disk to roll-weld the screen. The specific structure and working principle of the rolling welding module 55 are not the innovative part of the present technical solution, and are not shown in the figure. No further elaboration will be made here. During the process of the rolling welding module 55 welding the screen, the pushing structure plays a role. Specifically, the push rod 82 is located in the forward direction of the rolling welding module 55. Before the rolling welding wheel in the rolling welding module 55 contacts the screen, the ball 83 on the push rod 82 will first contact the screen. In this case, during the process of the push rod 82 rotating along the outer edge of the screen, it will contact one of the pressing plates 72 and push it to rotate. Fig. 9 As shown, for ease of understanding and expression, the flat plate 72 provided with the fixed plate 78 is named flat plate a, the flat plate 72 adjacent to the flat plate a counterclockwise is named flat plate b, the flat plate 72 adjacent to the flat plate b counterclockwise is named flat plate c, and the flat plate 72 adjacent to the flat plate c counterclockwise is named flat plate d. In the process of the rolling welding module 55 and the push rod 82 moving along the outer edge of the screen, the push rod 82 will first contact the flat plate a and push the flat plate a to rotate. When the flat plate a contacts the flat plate b, the flat plate a will push the flat plate b to rotate. By analogy, the four flat plates 72 will gather together under the pushing action of the push rod 82 and rotate synchronously under the pushing action of the push rod 82. , until the rolling welding wheel in the rolling welding module 55 moves along the outer edge of the screen. By setting the push rod 82, the rolling welding wheel in the rolling welding module 55 can be prevented from contacting the pressing plate 72 during the movement, and the pressing plate 72 can be prevented from causing adverse effects on the welding of the rolling welding module 55, thereby ensuring the welding effect of the rolling welding module 55 on the screen. It is worth noting that each pressing plate 72 is provided with a slot 76 on the bottom surface, and the slot 76 is arranged at the outer edge of the screen. The arrangement of the slot 76 can prevent the bottom surface of the pressing plate 72 from contacting the welding position of the screen, and prevent the friction loss of the pressing plate 72 on the welding position of the screen when the pressing plate 72 rotates, thereby preventing the pressing plate 72 from affecting the welding effect of the device on the screen.

[0072] After welding is completed, the lifting seat 3 moves upward, and the outer cylinder 61, the inner rod 62 and the flattening plate 64 will also move upward. When the outer cylinder 61 moves upward, the four flattening plates 72 will also move upward, which separates the flattening plate 64 and the four flattening plates 72 from the welded screen. The staff can remove the welded screen from the metal welding plate. Furthermore, the staff can manually rotate the four flattening plates 72 so that the four fixed magnetic sheets 74 on the four flattening plates 72 contact with the four positioning magnetic sheets 75, and manually reset the four flattening plates 72 to facilitate subsequent operations of the device. Example

[0073] Reference Figure 2 , 3 , 7, 8, 9 and Fig.10 A welding device for processing a vibrating screen mesh, wherein three connecting ropes 77 are arranged between four flattening plates 72, and two adjacent flattening plates 72 are connected by connecting ropes 77, and a fixing plate 78 (such as Fig. 9 shown);

[0074] A reset structure is provided on the frame 1, and the reset structure includes a sliding member and a driving member. The sliding member includes: two first support rods 91, both of which are fixed on the frame 1, and the two first support rods 91 are respectively located on both sides of the metal welding plate; an annular guide rail 92, fixed between the two first support rods 91, and the inner ring and the outer ring of the annular guide rail 92 are both provided with an annular groove 93; a sliding frame 94, which is slidably sleeved on the annular guide rail 92, and the sliding frame 94 is composed of a U-shaped frame and two blocks, and the opening of the U-shaped frame faces upward and is sleeved on the annular guide rail 92. Both blocks are fixed on the U-shaped frame, and the two blocks are respectively placed in two annular grooves 93; the push plate 95 is fixed on the side of the sliding frame 94, and the driving part includes: two second support rods 101, both fixed on the frame 1, and the two second support rods 101 are respectively located on both sides of the metal welding plate; the ring gear 102 is fixed between the two second support rods 101; the motor 103 is installed on the bottom surface of the sliding frame 94; the gear 104 is fixedly sleeved on the output shaft of the motor 103, and the gear 104 and the ring gear 102 are meshed with each other.

[0075] On the basis of Example 1, a reset structure for automatically resetting the four flattening plates 72 is provided on the frame 1. Specifically, when the flattening plate 64 and the four flattening plates 72 are reset to the initial position, the fixed plate 78 on the flattening plate a is located on the same plane as the pushing plate 95 on the sliding frame 94, that is, the fixed plate 78 on the flattening plate a is located on the rotation path of the pushing plate 95. When resetting, the motor 103 runs and drives the gear 104 to rotate. Since the gear 104 and the ring gear 102 are meshed with each other, the gear 104 can generate a rotation under the action of the ring gear 102 when rotating. The gear ring 102 rotates and rotates clockwise around the center of the gear ring 102. The meshing action of the gear ring 102 and the gear 104 enables the motor 103 to drive the sliding frame 94 to move, so that the sliding frame 94 moves on the annular guide rail 92. When the sliding frame 94 moves on the annular guide rail 92, it rotates clockwise around the outer cylinder 61. In this process, the pushing plate 95 contacts the fixed plate 78 and pushes the fixed plate 78 to move. When the fixed plate 78 moves, it can drive the pressing plate a to rotate. The pressing plates a and b, the pressing plates b and c, and the pressing plates a and b are pressed together. Plate c and pressing plate d are connected by connecting ropes 77. When pressing plate a is pushed, when the connecting rope 77 between pressing plate a and pressing plate b is stretched tight, pressing plate a can drive pressing plate b to rotate through the connecting rope 77. When the connecting rope 77 between pressing plate b and pressing plate c is stretched tight, pressing plate b can drive pressing plate c to rotate through the connecting rope 77. When the connecting rope 77 between pressing plate c and pressing plate d is stretched tight, pressing plate c can drive pressing plate d to rotate through the connecting rope 77. When the three connecting ropes 77 are all in When in the stretched state, the four pressing plates 72 are in a circumferential array distribution state. When the pressing plate a rotates to the initial position, the four fixed magnetic sheets 74 on the four pressing plates 72 are in contact with the four positioning magnetic sheets 75. At this time, the four fixed magnetic sheets 74 and the four positioning magnetic sheets 75 play a role in positioning the four pressing plates 72. The motor 103 is powered off and the reset structure stops running. In summary, the setting of the reset structure realizes the automatic reset of the four pressing plates 72. The automatic reset function does not require manual operation, thereby improving the working efficiency of the device and providing convenience for the actual use of the device.
