Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric cutting devices, in particular to a non-woven fabric cutting device. Background Art

[0002] At present, non-woven fabric machine workers place non-woven fabrics on a hydraulic cutting device and cut the non-woven fabrics into specific shapes through a mold to facilitate subsequent textile processing.

[0003] Most existing nonwoven cutting machines typically feature a frame, a drive belt mounted on top of the frame to transport the nonwoven fabric. A hydraulic press is installed on top of the frame, perpendicular to the direction of the drive belt's movement, and a pressure plate is located at the bottom of the hydraulic press. The nonwoven fabric is laid flat on the bottom of the hydraulic press, where it is pressed and fixed by the pressure plate, and then cut using other cutting mechanisms.

[0004] However, with this existing method, if the non-woven fabric has wrinkles or is not in a completely flat state, directly pressing the non-woven fabric will cause the non-woven fabric to be cut into an irregular shape, thereby reducing the quality rate of the finished product. Utility Model Content

[0005] The utility model mainly provides a non-woven fabric cutting device to solve the problem that in the existing method, if the non-woven fabric has wrinkles or is not in a completely flat state, directly pressing the non-woven fabric will cause the cutting shape of the non-woven fabric to be irregular, thereby reducing the quality rate of the finished product.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A non-woven fabric cutting device includes a hydraulic press and a pressing plate, including two pressing plates symmetrically arranged at the bottom of the hydraulic press, a connecting block is provided at the upper end of the outer side of each pressing plate, an L-shaped mounting block is vertically slidably connected to the connecting block, a driving displacement mechanism is provided on the L-shaped mounting block, a scraping strip is provided at the inner end of the driving displacement mechanism, and the scraping strip is driven by the driving displacement mechanism to scrape the surface of the non-woven fabric. During use, the hydraulic press drives the pressure plate, connecting block and other components to descend. When the two scraping bars descend and contact the surface of the non-woven fabric, they stop descending. At this time, the two pressure plates do not press the non-woven fabric. Then, the two scraping bars exert a certain pressure on the non-woven fabric under the influence of gravity. Then, the driving displacement mechanisms on both sides drive the respective scraping bars to move from the middle of the non-woven fabric to the other side, so that the scraping bars are used to flatten the surface of the non-woven fabric. When the scraping bar reaches the L-shaped mounting block, the hydraulic press continues to drive the corresponding components to descend, and at the same time, the L-shaped mounting block slides vertically on the connecting block until the two pressure blocks press and fix the non-woven fabric. Then, other mechanisms are used to cut the non-woven fabric. By adopting this structure, the displacement mechanism can drive the respective scrapers to move from the middle of the non-woven fabric to the other side, so that the scraper bar can be used to flatten the surface of the non-woven fabric, thereby preventing the non-woven fabric from being pressed and fixed by the pressure plate when there are wrinkles and it is not completely flattened, thereby ensuring the high quality rate of the non-woven fabric cut products; and when the two scraper bars are scraped at the same time, the non-woven fabric can be prevented from being displaced to one side; and the L-shaped mounting block is vertically slidably connected to the connecting block, which can cause the scraper bar to move upward when the pressure plate moves downward, and after the scraper bar moves, it is located on the inner side of the L-shaped mounting block, thereby avoiding damage to the scraper bar.

[0008] Furthermore, multiple slide bars are provided on the upper side of the L-shaped mounting block, and the connecting block is provided with sliding holes that fit the slide bars. Anti-slip blocks are provided on the upper ends of the slide bars. This structure allows the L-shaped mounting block to slide on the connecting block using the slide bars, and the anti-slip blocks prevent the L-shaped mounting block and corresponding components from falling off after the pressure plate is raised.

[0009] Furthermore, an elastic member is provided between the lower portion of the connecting block and the L-shaped mounting block. With this structure, after the elastic member is compressed, the scraping strip can have a certain pressing effect on the non-woven fabric, thereby better flattening the non-woven fabric.

[0010] Furthermore, the elastic member is a spring and is sleeved on the slide rod. The use of a spring has a low cost, and the sleeved installation on the slide rod is simple and practical.

[0011] Furthermore, the displacement mechanism adopts a cylinder, and the scraper is arranged at the output end of the cylinder. The cylinder is used to directly drive the scraper to move, which is simple and practical.

[0012] Beneficial effects: With this structure, the displacement mechanism can drive the respective scrapers to move from the middle of the non-woven fabric to the other side, so that the scraper bar can be used to flatten the surface of the non-woven fabric, thereby preventing the non-woven fabric from being pressed and fixed by the pressure plate when there are wrinkles and it is not completely flattened, thereby ensuring the high quality rate of the non-woven fabric cut products; and when the two scrapers are scraped at the same time, the non-woven fabric can be prevented from being displaced to one side; and the L-shaped mounting block is vertically slidably connected to the connecting block, which can cause the scraper bar to move upward when the pressure plate moves downward, and after the scraper bar moves, it is located on the inner side of the L-shaped mounting block, thereby avoiding damage to the scraper bar.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 、 Figure 2As shown, a non-woven fabric 9 cutting device of this embodiment includes a hydraulic press and a pressing plate 1, including two pressing plates 1 symmetrically arranged at the bottom of the hydraulic press. A connecting block 2 is provided on the upper outer end of each pressing plate 1. An L-shaped mounting block 3 is vertically slidably connected to the connecting block 2. A driving displacement mechanism 4 is provided on the L-shaped mounting block 3. A scraper 5 is provided at the inner end of the driving displacement mechanism 4. The scraper 5 scrapes the surface of the non-woven fabric 9 through the drive of the driving displacement mechanism 4. A plurality of sliding rods 6 are provided on the upper side of the L-shaped mounting block 3. The connecting block 2 is provided with sliding holes that match the sliding rods 6. The upper end of the sliding rod 6 is provided with an anti-slip block 7. An elastic member 8 is provided between the lower position of the connecting block 2 and the L-shaped mounting block 3. The elastic member 8 is a spring and is sleeved on the sliding rod 6. The driving displacement mechanism 4 is a cylinder, and the scraper 5 is provided at the output end of the cylinder. During use, the hydraulic press drives the pressure plate 1 and the connecting block 2 and other components to descend. When the two scraper strips 5 descend to contact the surface of the non-woven fabric 9, they stop descending. At this time, the two pressure plates 1 do not press the non-woven fabric 9. Then, the two scraper strips 5 have a certain pressure on the non-woven fabric 9 under the influence of gravity. Then, the driving displacement mechanisms 4 on both sides drive the respective scraper strips 5 to move from the middle of the non-woven fabric 9 to the other side, so that the scraper strips 5 are used to flatten the surface of the non-woven fabric 9; when the scraper strip 5 reaches the L-shaped mounting block 3, the hydraulic press continues to drive the corresponding components to descend, and at the same time, the L-shaped mounting block 3 slides vertically on the connecting block 2 until the two pressure blocks press and fix the non-woven fabric 9; then other mechanisms are used to cut the non-woven fabric 9. By adopting this structure, the displacement mechanism 4 can drive the respective scrapers 5 to move from the middle of the non-woven fabric 9 to the other side, so that the scraper 5 can be used to scrape the surface of the non-woven fabric 9 flat, thereby preventing the non-woven fabric 9 from being pressed and fixed by the pressing plate 1 when there are wrinkles and it is not completely flattened, thereby ensuring the high quality rate of the finished product of the non-woven fabric 9; and when the two scraper bars 5 are scraped at the same time, the non-woven fabric 9 can be prevented from being displaced to one side; and the L-shaped mounting block 3 is vertically slidably connected to the connecting block 2, which can cause the scraper 5 to move upward when the pressing plate 1 moves downward, and after the scraper bar 5 moves, it is located on the inner side of the L-shaped mounting block 3, thereby preventing the scraper bar 5 from being damaged.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
