Description

Technical Field

[0001] The present application relates to the technical field of cutting machines, and in particular to a needle felt cutting machine. Background Art

[0002] Needle felt is a material formed by consolidating short or filament fibers into a felt-like form through a needle-punching process. It is a sheet-like material formed by directly entanglement of fibers through friction and cohesion between the fibers, as well as the action of needle punching, without going through the spinning and weaving steps. When needle-punched felt products are mass-produced, such as carpets or floor mats, a cutting machine is used to cut the felt horizontally into blocks.

[0003] After searching, a Chinese patent with publication number CN220099498U discloses a needle felt cutting machine, which can adapt to needle felts of different thicknesses and flatten the needle felts to reduce wrinkles on the surface of the needle felts. However, when the cutter is working, since the cutting blade is in direct contact with the fibers of the needle felt, the fibers may adhere to the cutting edge or surface of the cutting blade. The fibers adhered to the cutting blade will change the shape of the cutting edge of the cutting blade. The originally sharp cutting edge may become irregular due to the attached fibers, which will directly affect the cutting accuracy. Therefore, a needle felt cutting machine is proposed to solve the above problem. Summary of the Invention

[0026] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0028] See also Figure 1-8 , the utility model provides a technical solution for a needle felt cutting machine:

[0029] A needle felt cutting machine includes a body 1, a feeding channel 2 is formed on the upper surface of the body 1, a bracket 3 is fixedly connected to the upper surface of the body 1, a cutting push rod 4 is fixedly connected to the upper surface of the bracket 3, the output end of the cutting push rod 4 passes through the inner top wall of the bracket 3 and is fixedly connected to a cutting knife 5, two dust removal parts 6 are respectively provided on the inner wall of the bracket 3, the two dust removal parts 6 are respectively located on the front and rear sides of the cutting knife 5, a scraping protrusion 8 is formed on the top of the dust removal part 6 close to the cutting knife 5, and the scraping protrusion 8 can remove fibers when the cutting knife 5 moves.

[0030] Specifically, the output end of the cutting push rod 4 drives the cutting knife 5 to descend to cut and reset the needle felt. By providing two scraping members and a scraping protrusion 8, the fibers on the surface of the cutting knife 5 are scraped off when the cutting knife 5 is raised or lowered, thereby solving the problem of the cutting accuracy being affected by the adhesion of the fibers.

[0031] A cavity 9 is formed inside the debris removing piece 6, and a through opening is provided on the side of the debris removing piece 6 away from the cutting knife 5, and a collecting box 10 is provided in the through opening. A feed port 11 is provided on the top of the debris removing piece 6. By providing the feed port 11 and the collecting box 10, it is convenient to collect the fiber scraps scraped when the cutting groove is lowered to prevent them from falling on the needle-punched felt.

[0032] The cross section of the scraping protrusion 8 is triangular, and a slanted opening 12 is provided at the top of the scraping protrusion 8. By setting the cross section of the scraping protrusion 8 to be triangular, it is convenient for it to be close to the cutting knife 5 for scraping. By providing the slanted opening 12, it is convenient for the cutting knife 5 to enter between the two scraping protrusions 8 when it descends.

[0033] A through-hole 13 is provided on the upper surface of the bracket 3, and a slide rod 14 is fixedly connected to the inner wall of the through-hole 13. A slider 15 is fixedly connected to the upper surface of the debris removing component 6. A sliding hole is provided on the front of the slider 15, and the inner wall of the sliding hole is slidably connected to the surface of the slide rod 14. By setting the slide rod 14 and the slider 15, the two debris removing components 6 can be movable to adapt to the shape of the cutting knife 5.

[0034] The surface of the slide rod 14 is sleeved with a spring 16, and the two ends of the spring 16 are fixedly connected to the opposite surfaces of the front and rear sliders 15 respectively. By setting the spring 16, a pulling force is generated on the springs 16 on both sides of the front side, so that they tend to approach each other, and then the two scraping members tend to approach each other, so that when the cutting knife 5 descends, the scraping protrusion 8 can be close to the surface of the cutting knife 5, thereby improving the cleaning effect. At the same time, the two springs 16 are used to automatically reset the two debris removing members 6.

[0035] A driving push rod 17 is fixedly connected to the upper surface of the bracket 3, and a trapezoidal push block 18 is fixedly connected to the output end of the driving push rod 17. The top of the slider 15 extends to the outside of the through-opening 13, and the push block 18 is located between the front and rear sliders 15. The output of the driving push rod 17 drives the push block 18 to move outward, so that the two sliders 15 overcome the force of the spring 16 and move away from each other, thereby driving the two debris removing parts 6 to move away from each other, preventing them from scraping fibers when the cutting knife 5 rises, and reducing fiber debris falling on the needle-punched felt.

[0036] The inner wall of the feeding channel 2 is rotatably connected to a feed roller 19, and a motor 7 is fixedly connected to one side of the machine body 1. The output end of the motor 7 is fixedly connected to the feed roller 19, and the surface of the feed roller 19 is provided with friction protrusions. The feed roller 19 is driven to rotate by the output end of the motor 7, so that the needle-punched felt located under the feed roller 19 moves forward under the action of friction force, wherein the inner bottom of the feeding channel 2 and the position corresponding to the feed roller 19 are also provided with friction protrusions.

[0037] Working principle: When the needle felt cutting machine is used, the user first lays the needle felt on the feeding channel 2 and places its end under the feeding roller 19, then starts the motor 7. The output end of the motor 7 drives the feeding roller 19 to rotate, so that the needle felt under the feeding roller 19 moves forward under the action of friction. After reaching the specified length, the motor 7 stops, the cutting push rod 4 starts, and the output end of the cutting push rod 4 drives the cutting knife 5 to descend to cut the needle felt and reset it. Then the motor 7 starts again to feed the needle felt. In this way, the needle felt is cut into blocks. Under normal circumstances, the output end of the driving push rod 17 is in a retracted state. At this time, the spring 16 generates a pulling force on the springs 16 on both sides of the front side, so that they have a tendency to approach each other, and the needle felt is cut into blocks. This makes the two scraping members tend to approach each other. When the cutting knife 5 descends, the scraping protrusion 8 can be close to the surface of the cutting knife 5, scraping the fibers on the surface of the cutting knife 5, and the scraped fibers fall into the collection box 10 from the feed port 11, thereby improving the cleaning effect. When the cutting knife 5 needs to be reset, the output of the push rod 17 is first driven to drive the push block 18 to move outward. The push block 18 enables the two sliders 15 to overcome the force of the spring 16 and move away from each other, thereby driving the two debris removing members 6 away from each other. At this time, the scraping protrusion 8 is away from the cutting knife 5, and will not scrape the fibers on its surface when the cutting knife 5 rises and resets, thereby reducing the fiber debris falling on the needle-punched felt, thereby solving the problem of the cutting accuracy affected by the adhesion of fibers in the prior art.
