Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for filter cloth production. Background Technology

[0002] In the production of activated carbon filter cloth, cutting is a key step to ensure product specifications. However, existing cutting devices for filter cloth production generally have problems with missing or imperfect cleaning functions, which reduces the quality of filter cloth production.

[0003] Because activated carbon filter cloth is usually made by loading activated carbon particles onto the surface of a base fabric, and activated carbon particles themselves are somewhat brittle, some particles may break due to friction and vibration during processing (such as impregnation, drying, calendering, etc.), producing fine carbon ash. This carbon ash is easily adsorbed on the surface of the filter cloth, especially in areas where the activated carbon coating is thicker or the bonding is not strong enough. In addition, the base fabric of the filter cloth is woven from fibers. During the winding process, friction between filter cloths and between the filter cloth and the equipment may cause some fibers to be hooked, pulled, and broken off, especially at the edges of the base fabric or in areas with lower weave density, where fibers are more likely to fall off and adhere to the surface. Existing cutting devices often directly transport the filter cloth to be cut to the cutting structure for cutting, ignoring the problem of impurities such as fibers and carbon ash easily adhering to the surface of the filter cloth during the initial processing and transportation. In order to meet the requirements of subsequent use, additional cleaning equipment is required to clean the filter cloth a second time after the cutting process. This not only increases equipment investment and production costs, but also makes the production process cumbersome. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 The existing technology requires additional cleaning equipment to clean the filter cloth after the cutting process, which increases equipment investment and production costs, and also makes the production process cumbersome. This invention addresses the problem of simultaneously performing cleaning and cutting, ensuring the quality of the cut filter cloth, eliminating the need for additional cleaning equipment to remove carbon ash and fibers from the surface of the cut filter cloth, and improving filter cloth production efficiency. This embodiment provides a cutting device for filter cloth production. This cutting device for filter cloth production, according to the attached... Figure 1-7 As shown, the system includes a support frame 1 and a cutting structure 2 on top of it. A feeding structure 3 and a pulling structure 4 are respectively located on both sides of the cutting structure 2. A sealing box 5, fixedly installed on the top of the support frame 1, is located between the feeding structure 3 and the cutting structure 2. A cleaning component 6 is installed inside the sealing box 5. During use, the activated carbon filter roll is first connected to the feeding roller 31. Then, one end of the filter cloth is passed through the sealing box 5 and the cutting structure 2 and flattened. The pulling structure 4 then clamps and pulls the end of the filter cloth. After the pulling structure 4 pulls the filter cloth to a certain length, the cutting structure 2 cuts the filter cloth. After cutting, the pulling structure 4 releases the material, causing the cut filter cloth to fall onto the top of the bottom platform for collection.

[0019] To address the issue of improving filter cloth production efficiency by eliminating the need for additional cleaning equipment to remove carbon ash and fibers from the cut filter cloth surface, such as... Figure 3 - Figure 5As shown, the cleaning component 6 includes a lower cleaning roller 61 and an upper cleaning roller 62 disposed inside the sealed box 5 for scraping and limiting the filter cloth surface. Air knives 63 are respectively disposed on one side of the lower cleaning roller 61 and the upper cleaning roller 62 for cleaning carbon ash from the filter cloth surface. The air knives 63 are respectively disposed at the top and bottom of the filter cloth. The air knives 63 blow airflow simultaneously onto both sides of the filter cloth, thereby removing the carbon ash adhering to both sides of the filter cloth under the action of the airflow. Under the action of the dust pump 65, a negative pressure state is formed inside the sealed box 5, thereby allowing the cleaned fibers and carbon ash to be sucked in together through the dust collection hoods 64 and dust collection pipes 67 on both sides and collected inside the dust collection box 66, realizing the cleaning of carbon ash and fibers on the surface of the filter cloth before cutting. Figure 1 - Figure 7 As shown, dust collection hoods 64 are fixedly installed on the inner walls of both sides of the sealed box 5, and a dust pump 65 and a dust collection box 66 are fixedly installed at the bottom of the sealed box 5. Dust collection pipes 67 communicating with the interior of the dust collection box 66 are fixedly installed on the outer walls of both sides. The other end of the dust collection pipe 67 is fixedly installed with the dust collection hood 64. During the material pulling and cutting process, the cleaning component 6 inside the sealed box 5 can clean the residual fibers and carbon ash on the surface of the filter cloth, thereby ensuring the quality of the cut filter cloth and avoiding the need to use additional cleaning equipment to clean the cut filter cloth after cutting. This ensures that the cutting and cleaning work can be carried out simultaneously, improving the production efficiency of the filter cloth.

[0020] The cutting structure 2 includes a crossbeam 21 fixedly installed between the vertical beams on both sides of the support frame 1. A cutting blade 22 is slidably connected to the outer wall of the crossbeam 21. A pressure plate 23 is provided at the bottom of the crossbeam 21, and a cylinder 24 is fixedly installed at the top to drive the pressure plate 23 to move. During the process of cutting the filter cloth, the cylinder 24 drives the pressure plate 23 to move down and press one end of the filter cloth against the top of the support platform, so that the cutting blade 22 can cut the filter cloth. When the pulling structure 4 moves to the pressure plate 23 to clamp the filter cloth, the pressure plate 23 moves up, so that the pulling structure 4 can pull the filter cloth.

[0021] The feeding structure 3 includes a feeding roller 31 set on the top of the support frame 1, and multiple sets of traction rollers 32 set on one side of the feeding roller 31. The traction rollers 32 are used to guide the movement of the filter cloth.

[0022] Example 2 Based on Example 1, such as Figure 1 - Figure 5As shown, due to the limited internal space of the sealing box 5, in order to facilitate the insertion of the filter cloth between the two sets of cleaning rollers, the sealing box 5 is designed as a split unit. This makes it easy to open the sealing cover 52 on the top of the sealing box 5, and to move the upper cleaning roller 62 away from the top of the lower cleaning roller 61. This allows the operator to easily pass one end of the filter cloth through the inside of the sealing box 5 and flatten it on the top of the lower cleaning roller 61, facilitating the installation of the filter cloth inside the sealing box 5 for processing. This improves the convenience of installing the filter cloth inside the sealing box 5. The sealing box 5 consists of a box body 51 and a sealing cover 52. One outer wall of the sealing cover 52 is fixedly installed with a rotating connection to the inner walls on both sides of the box body 51. The connecting shaft 521 is connected, and the other side of the sealing cover 52 is threadedly connected to the box body 51 by a fixing bolt 522. First, the fixing bolt 522 is removed from the sealing cover 52 and the box body 51. Then, the top sealing cover 52 is pulled to flip it, so that the sealing cover 52 can be opened, making it easy for the staff to flatten the filter cloth and pass it through the inside of the sealing box 5. Then, the sealing cover 52 is closed, which can automatically drive the upper cleaning roller 62 to be installed on the top of the lower cleaning roller 61, so that the filter cloth is clamped between the two sets of cleaning rollers. The two sets of cleaning rollers clean the limiting and carbon ash on the surface of the filter cloth before cutting, improving the quality of the filter cloth after cutting.

[0023] Because the base fabric of the filter cloth is woven from fibers, friction between filter cloths and between the filter cloth and the equipment during the winding process can cause some fibers to be hooked, pulled, and broken off, especially at the edges of the base fabric or in areas with lower weave density, where fibers are more likely to detach and adhere to the surface. The use of two sets of cleaning rollers can scrape off the fibers adhering to the filter cloth surface. Figure 3 - Figure 4 The lower cleaning roller 61 is located directly below the upper cleaning roller 62, and clamping components 7 for elastically holding the filter cloth are respectively provided on the opposite side of the lower cleaning roller 61 and the upper cleaning roller 62. The top of the sealing cover 52 is provided with an adjustment component 8 for adjusting the distance between the lower cleaning roller 61 and the upper cleaning roller 62 to accommodate filter cloths of different thicknesses. It should be noted that both sets of cleaning rollers are made of nylon roller brushes, which are relatively soft, to avoid abrasion on the surface of the filter cloth during the cleaning process.

[0024] To prevent the two sets of cleaning rollers from rigidly clamping the filter cloth during its movement, a clamping assembly 7 is installed to protect the filter cloth during movement, avoiding rigid clamping that could easily cause wear on the filter cloth surface and improving the quality of the filter cloth surface cleaning process. Figure 6 The clamping assembly 7 includes a second fixing plate 73 disposed at the bottom of the sealing cover 52 and fixedly installed at the bottom of the box body 51. Multiple sets of drive springs 72 are fixedly installed on the top of the second fixing plate 73 along its own length direction. A first fixing plate 71 is fixedly installed on the top of the drive springs 72. The two sets of first fixing plates 71 are rotatably connected to the lower cleaning roller 61 and the upper cleaning roller 62 respectively between the top two side plates of the top of the first fixing plates 71.

[0025] To improve the cleaning performance of the two sets of cleaning rollers on filter cloths of varying thicknesses, an adjustment component 8 is installed on the top of the sealing cover 52. This allows for adjustment of the height of the upper cleaning roller 62 and the distance between the two sets of cleaning rollers, thus enabling the cleaning of filter cloths of different thicknesses. Figure 4 - Figure 6 As shown, the adjustment assembly 8 includes an adjustment screw 81 threaded inside the sealing cover 52 and a drive knob 82 located on its top. The drive knob 82 is fixedly installed on the top of the adjustment screw 81, and the bottom end of the adjustment screw 81 is rotatably connected to the top of the second fixing plate 73 at the upper cleaning roller 62. Rotating the drive knob 82 causes the adjustment screw 81 to be threaded inside the sealing cover 52, so that the bottom end of the adjustment screw 81 rotates to the top of the second fixing plate 73, pushing or pulling the upper cleaning roller 62 to move, thereby adjusting the distance between the two sets of cleaning rollers.
