Description

Technical Field

[0001] The invention relates to the technical field of filter cloth cutting equipment for filter presses, in particular to a filter cloth cutting auxiliary device for filter presses. Background Art

[0002] A filter press is a filtering and separation equipment commonly used in the industrial field, in which the filter cloth is an important component of the filter press. Generally, for a plate filter press, the frame is generally composed of multiple filter plates and filter frames stacked together to form a filter chamber, and the filter cloth is used to separate the filter chambers. Under the squeezing action of the filtering driving force, the filter cloth can separate the solid particles in the liquid into the filter chamber. The filter cloth usually includes a first cloth body and a second cloth body, which are cut from a raw mesh cloth. The first cloth body and the second cloth body have exactly the same shape and structure, and are square. A circular feed hole is opened at the center of the square cloth body, and the external filtrate can be injected into the filter chamber through the circular feed hole and connected in series with the next filter chamber. In addition, a mesh cloth cylinder is passed between the two circular feed holes of the first cloth body and the second cloth body, and is respectively sewed with the feed holes at both ends. The sewn first cloth body and the second cloth body are respectively covered on both sides of the filter plate, and the mesh cloth cylinder of the sewed connection part is sleeved in the feed port of the filter plate to form a filter cloth.

[0003] The existing filter cloth for filter presses is generally cut by moving a laser knife driven by three coordinates to cut the plane of the mesh cloth raw material, that is, the overall edge of the square filter cloth is first cut, and then the circular feed hole of the filter cloth is partially cut. However, for the cutting trajectory of the filter cloth for filter presses, which has basically the same structure and shape and a small size range, if a three-coordinate cutting machine is used, it is necessary to first program and calculate the cutting route, and then cut in the order of the periphery first and then the middle.

[0042] Please combine Figure 8As shown, the first mounting seat mechanism and the second mounting seat mechanism both include a mounting plate 27, one side of the two mounting plates 27 are fixedly connected with a clamping table 29, and the two sides of the two clamping tables 29 are respectively provided with limiting slide bars 30 fixedly connected to the upper and lower sides of the clamping tables 29, and the clamping table 29 and the two limiting slide bars 30 on each mounting plate 27 are simultaneously slidably connected with a third slider 28, and the limiting slide bars 30 located on both sides of the third slider 28 are sleeved with springs 31, and one end of the plurality of springs 31 is respectively fixedly connected to the mounting plate 27, and the other end of the plurality of springs 31 is respectively fixedly connected to one side of the third slider 28;

[0043] The third slider 28 on the first mounting seat mechanism is fixedly connected to one side of the first fixing sleeve 32, and the mounting plate 27 on the first mounting seat mechanism is fixedly connected to one end of the push rod 22 and the adjusting rod 12 respectively;

[0044] The third slider 28 on the second mounting seat mechanism is fixedly connected to one side of the second fixing sleeve 33 , and the mounting plate 27 on the second mounting seat mechanism is fixedly connected to the lower side of the first slider 18 .

[0045] Please combine Figure 1 and Figure 3 As shown, the frame shell mechanism includes a plurality of limit sleeves 5 fixedly connected to the upper side of the shaping pressure plate 9, each limit sleeve 5 is connected to the shaping pressure plate 9, and the inner side of each limit sleeve 5 is slidably connected with a load-bearing rod 1, and the upper ends of the plurality of load-bearing rods 1 are commonly fixedly connected with a dust cover 2, and the outer side of the dust cover 2 is fixedly connected with a control module 4. The dust cover 2 can prevent external dust from entering the interior of the cutting auxiliary device, and at the same time helps to improve the cutting accuracy of the device and reduce the error of the cutting system. The upper side of the dust cover 2 is provided with a lifting drive mechanism that pulls the shaping pressure plate 9 in or out from the bottom of the dust cover 2.

[0046] Please combine Figure 1 As shown, the lifting drive mechanism includes an oil cylinder 3 fixedly connected to the upper side of the dust cover 2, and the output end of the oil cylinder 3 passes downward through the dust cover 2 and is fixedly connected to the upper side of the fixing plate.

[0047] Working principle: Start the oil cylinder 3 to push the fixed plate 16, the shaping plate 9 and the main limit frame 8 to move downward as a whole, wherein each limit sleeve 5 slides downward along the surface of the load-bearing rod 1, and the outer edge of the shaping plate 9 slides downward along the inner side of the dust cover 2. When the shaping plate 9 drops to the height preset by the control module 4, it stops descending. At this time, the raw material mesh for cutting the filter cloth is already located at the lower side of the shaping plate 9. At this time, the servo motor 15 starts to push the dovetail slide 19 and the limit table 21 to rotate;

[0048] For the second laser cutter 14, the second positioning bolt 24 can be rotated forward. At this time, the first slider 18 can slide left and right along the dovetail slide 19, and drive the second mounting seat mechanism, the second fixing sleeve 33 and the second laser cutter 14 to slide left and right along the dovetail slide 19, thereby realizing the function of cutting the round hole feed openings of different sizes;

[0049] For the first laser cutter 13, when the limit table 21 swings, the card slot 20 can push the push rod 22 to rotate and move. At this time, the second slider 25 can slide back and forth along the inside of the card slot 20. The lower part of the push rod 22 is fixedly connected to the first mounting seat mechanism. When the first mounting seat mechanism, the first fixed sleeve 32 and the first laser cutter 13 are pushed to rotate, the adjusting rod 12 and the connecting tube 11 are driven to rotate. By operating the No. 1 positioning bolt 23, the telescopic distance of the adjusting rod 12 inside the connecting tube 11 can be adjusted, thereby achieving cutting without In accordance with the requirements of the outer square size of the filter cloth, under the driving action of the connecting tube 11, one end of the connecting tube 11 pushes the connecting plate 6 to move along the No. 1 slide groove 10 inside the main limit frame 8, and the two ends of the connecting plate 6 are rotatably connected to the shuttle 7. Due to the special structure of its head, the shuttle 7 can drive the connecting plate 6 to slide smoothly along the inner wall of the No. 1 slide groove 10. The main limit frame 8 adopts rounded corners at each turning joint of the No. 1 slide groove 10, thereby ensuring that the connecting plate 6 and the two shuttles 7 can pass smoothly inside the No. 1 slide groove 10;

[0050] For the first mounting seat mechanism and the second mounting seat mechanism, when the first laser knife 13 or the second laser knife 14 interferes with external objects, no matter it comes from the cutting table below or the interference from the mesh cloth, the first laser knife 13 is used as a representative to interpret its mechanical movement principle. When the first laser knife 13 is interfered, the first laser knife 13 can directly push the first fixed sleeve 32 and the third slider 28 upward, wherein the third slider 28 slides upward and downward along the card table 29 and the limit slide bar 30, the two springs 31 at the top are deformed and compressed, and the two springs 31 at the bottom are deformed and stretched, thereby converting the kinetic energy generated by the interference into the elastic potential energy of the spring 31, so that the spring 31 plays a buffering role and plays a role in protecting the structural safety of the two laser knives.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
