Description

Technical Field

[0001] The utility model relates to the technical field of sintered mesh filter elements, in particular to a stainless steel sintered mesh filter element straight seam automatic welding device. Background Art

[0002] Stainless steel sintered mesh filter element is a common type of filter element, usually used for liquid or gas filtration. It is made of stainless steel sintered mesh and has excellent corrosion resistance and high temperature resistance. It is suitable for filtration needs in various harsh environments. It has high filtration accuracy and good filtration efficiency, and can effectively remove particles, impurities, etc. Common application areas include petrochemical, food and beverage, water treatment and other industries.

[0003] When processing stainless steel sintered mesh filter elements, a single filter mesh needs to be rolled into a cylindrical shape and welded together. The current operation is usually for workers to wrap the filter mesh on a shaping column and press and fix its two ends with their hands, and then use a welding gun to weld the junction of the two ends of the filter mesh. However, the hand pressing method not only has a poor fixing effect, but may also cause sliding and offset during the welding process, resulting in a decrease in welding quality. It also poses certain safety hazards and is prone to cause hand injuries. Utility Model Content

[0004] The utility model aims to provide a stainless steel sintered mesh filter element straight seam automatic welding device which is safe to use and can quickly fix the filter screen.

[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0006] A stainless steel sintered mesh filter element straight seam automatic welding device comprises an L-shaped base, wherein the outer surfaces of the vertical plates of the L-shaped base are respectively mounted with a shaping column and a shaping sleeve, wherein the shaping column and the shaping sleeve are coaxially arranged, and a shaping groove is provided between the shaping column and the shaping sleeve, and a second mounting shell is mounted on the upper surface of the horizontal plate of the L-shaped base, wherein L-shaped plates are provided on both sides of the shaping sleeve, and a clamping mechanism is provided inside the second mounting shell that can drive the two L-shaped plates to move in opposite directions simultaneously, and a clamping block is provided at the end of each L-shaped plate. A welding gun is mounted on the upper side of the shaping sleeve via an electric push rod, and a toggle block is mounted on the upper side of the shaping column via a connecting plate, wherein the lower surface of the toggle block is in contact with the outer surface of the shaping column, and a first mounting shell is mounted on the top of the vertical plate of the L-shaped base, wherein two mounting grooves are provided inside the first mounting shell, and a moving mechanism is provided inside each of the two mounting grooves, wherein the two moving mechanisms can respectively drive the electric push rod and the connecting plate to move linearly.

[0007] It can be seen that through the arrangement of the shaping column, the shaping sleeve and the shaping groove, the filter screen can be inserted into the shaping groove and its two ends are extended to the outside respectively. At this time, the shaping groove plays a limiting role on the filter screen, and both ends of the filter screen are inclined inward, and then the two clamping blocks are driven to approach inward at the same time through the clamping mechanism, thereby driving the two ends of the filter screen to gather inward and press them against the outer surface of the shaping column, thereby achieving the purpose of quickly fixing the filter screen. Subsequently, the welding gun is driven by the moving mechanism to weld the junction, which is safer. After the welding is completed, the toggle block can be driven by the moving mechanism to move linearly, and the filter screen welded into a cylindrical shape can be quickly removed from the shaping column, thereby improving the working efficiency.

[0008] Furthermore, the clamping mechanism includes a second mounting shell installed on the upper surface of the L-shaped base horizontal plate, and the interior of the second mounting shell is rotatably connected to a first threaded rod having a pair of reverse threads, a pair of first nut seats are installed on the reverse threads of the first threaded rod, and the two first nut seats are respectively connected to the bottom of the two L-shaped plates, and a first motor is installed on the outer surface of the second mounting shell, and the output shaft of the first motor is connected to the first threaded rod.

[0009] When the first motor is started to drive the first threaded rod to rotate, since the two pairs of threads on the first threaded rod are set in opposite directions, the two first nut seats installed on the opposite threads can be driven to move in opposite directions. By controlling the forward and reverse rotation of the first motor, the two L-shaped plates can be driven to move closer to or away from each other, and the filter screen can be quickly fixed by the clamping block.

[0010] Furthermore, both moving mechanisms include a second threaded rod rotatably connected to the inside of the mounting groove, a second nut seat is installed on the outer surface of the second threaded rod, and the electric push rod and the connecting plate are respectively installed on the bottom of the two second nut seats, and two second motors are installed on the outer surface of the first mounting shell, and the output shafts of the two second motors are respectively connected to the two second threaded rods.

[0011] When the second motor is started to drive the second threaded rod to rotate, the second nut seat can be driven to move along the surface of the second threaded rod, thereby achieving the purpose of driving the electric push rod or the connecting plate to move linearly. The welding gun is driven by the electric push rod to move, and the filter connection can be welded. The toggle block is driven to move by the connecting plate, and the filter welded into a cylindrical shape can be quickly removed from the shaping column.

[0012] Furthermore, a fixed plate is installed at the end of the L-shaped plate, a telescopic rod is connected to the lower surface of the fixed plate, and the end of the telescopic rod is connected to the clamping block. A spring is sleeved on the outer surface of the telescopic rod, and the two ends of the spring are respectively in contact with the fixed plate and the clamping block.

[0013] Through the setting of the telescopic rod and the spring, a downward thrust can be applied to the clamping block. Therefore, when the clamping mechanism drives the two clamping blocks closer to each other, the clamping blocks will be pressed against the surface of the filter screen and move. The friction generated by the compression can pull the filter screen. The two clamping blocks simultaneously pull the two ends of the filter screen inward, so that the filter screen can be tightly wrapped on the outer surface of the shaping column, thereby improving product quality.

[0014] Furthermore, both sides of the outer surface of the L-shaped plate are connected to reinforcement plates, and the ends of the reinforcement plates are connected to the fixing plates.

[0015] By setting the reinforcement plate, the connection points between the fixed plate and the L-shaped plate can be increased, so that the fixed plate is subjected to more uniform force and the structure is more solid.

[0016] Furthermore, supporting feet are installed at the four corners of the bottom of the L-shaped base, and anti-slip pads are provided at the bottom of the supporting feet.

[0017] The provision of the supporting feet and the anti-skid pads can play an anti-skid role, so that the device can be stably placed on the table for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, a stainless steel sintered mesh filter element straight seam automatic welding device includes an L-shaped base 100, including an L-shaped base 100, the outer surfaces of the vertical plates of the L-shaped base 100 are respectively installed with shaping columns 101 and shaping sleeves 102, and the shaping columns 101 and the shaping sleeves 102 are coaxially arranged, and a shaping groove 103 is provided between the shaping columns 101 and the shaping sleeves 102, a second mounting shell 112 is installed on the upper surface of the horizontal plate of the L-shaped base 100, L-shaped plates 104 are provided on both sides of the shaping sleeves 102, and a clamping mechanism 200 that can drive the two L-shaped plates 104 to move in opposite directions at the same time is provided inside the second mounting shell 112, and the ends of the two L-shaped plates 104 are provided with clamping blocks 105. A welding gun 107 is installed on the upper side of the forming sleeve 102 through an electric push rod 106, and a toggle block 108 is installed on the upper side of the forming column 101 through a connecting plate 111. The lower surface of the toggle block 108 fits into the outer surface of the forming column 101, and a first mounting shell 109 is installed on the top of the vertical plate of the L-shaped base 100. Two mounting grooves 110 are provided inside the first mounting shell 109, and a moving mechanism 300 is provided inside the two mounting grooves 110. The two moving mechanisms 300 can respectively drive the electric push rod 106 and the connecting plate 111 to move linearly.

[0025] When in use, first insert the filter into the shaping groove 103 and extend its two ends to the outside. At this time, the shaping groove 103 limits the filter, and both ends of the filter are tilted inward. Then, the two L-shaped plates 104 are driven inward by the clamping mechanism 200, and the L-shaped plates 104 drive the two clamping blocks 105 inward. The two clamping blocks 105 press the two ends of the filter against the outer surface of the shaping column 101, so that the filter can be quickly fixed. Then, the electric push rod 106 is started to drive the welding gun 107. The moving mechanism 300 drives the electric push rod 106 and the welding gun 107 to move linearly, so that the welding gun 107 can perform linear welding at the intersection, and the filter screen is processed into a cylindrical structure. The two clamping blocks 105 are then moved away from each other by the clamping mechanism 200, and the connecting plate 111 and the toggle block 108 are driven by the moving mechanism 300 to move linearly, so that the filter screen welded into a cylindrical shape can be quickly removed from the shaping column 101, thereby improving working efficiency.

[0026] Specifically, the clamping mechanism 200 includes a second mounting shell 112 mounted on the upper surface of the horizontal plate of the L-shaped base 100, and the interior of the second mounting shell 112 is rotatably connected to a first threaded rod 201 having a pair of reverse threads, and a pair of first nut seats 202 are installed on the reverse threads of the first threaded rod 201, and the two first nut seats 202 are respectively connected to the bottoms of the two L-shaped plates 104, and a first motor 203 is installed on the outer surface of the second mounting shell 112, and the output shaft of the first motor 203 is connected to the first threaded rod 201. When the first motor 203 is started to drive the first threaded rod 201 to rotate, since the two pairs of threads on the first threaded rod 201 are set in reverse, the two first nut seats 202 installed on the reverse threads can be driven to move in reverse. By controlling the forward and reverse rotation of the first motor 203, the two L-shaped plates 104 can be driven to move closer or farther away from each other, and the filter screen can be quickly fixed by the clamping block 105.

[0027] Specifically, the two moving mechanisms 300 both include a second threaded rod 301 rotatably connected to the inside of the mounting groove 110, a second nut seat 302 is installed on the outer surface of the second threaded rod 301, and the electric push rod 106 and the connecting plate 111 are respectively installed on the bottom of the two second nut seats 302, and two second motors 303 are installed on the outer surface of the first mounting shell 109, and the output shafts of the two second motors 303 are respectively connected to the two second threaded rods 301. When the second motor 303 is started to drive the second threaded rod 301 to rotate, the second nut seat 302 can be driven to move along the surface of the second threaded rod 301, thereby achieving the purpose of driving the electric push rod 106 or the connecting plate 111 to move linearly. The welding gun 107 is driven to move by the electric push rod 106, and the filter connection can be welded. The toggle block 108 is driven to move by the connecting plate 111, and the filter welded into a cylindrical shape can be quickly removed from the shaping column 101.

[0028] Specifically, a fixed plate 400 is installed at the end of the L-shaped plate 104, and a telescopic rod 401 is connected to the lower surface of the fixed plate 400, and the end of the telescopic rod 401 is connected to the clamping block 105. A spring 402 is sleeved on the outer surface of the telescopic rod 401, and the two ends of the spring 402 are respectively in contact with the fixed plate 400 and the clamping block 105. Through the setting of the telescopic rod 401 and the spring 402, a downward thrust can be applied to the clamping block 105. Therefore, when the clamping mechanism 200 drives the two clamping blocks 105 to approach each other, the clamping blocks 105 will be pressed against the surface of the filter screen and move. The friction force generated by the pressing can pull the filter screen. The two clamping blocks 105 simultaneously pull the two ends of the filter screen inward, so that the filter screen can be tightly wrapped around the outer surface of the shaping column 101, thereby improving product quality.

[0029] Specifically, reinforcement plates 500 are connected to both sides of the outer surface of the L-shaped plate 104, and the ends of the reinforcement plates 500 are connected to the fixed plate 400. By setting the reinforcement plates 500, the connection points between the fixed plate 400 and the L-shaped plate 104 can be increased, so that the fixed plate 400 is subjected to more uniform force and the structure is more solid.

[0030] Specifically, the four corners of the bottom of the L-shaped base 100 are equipped with supporting feet 600, and the bottom of the supporting feet 600 is provided with anti-skid pads. The setting of the supporting feet 600 and the anti-skid pads can play an anti-skid role, so that the device can be stably placed on the table for use.

For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
