Description

Technical Field

[0001] The utility model relates to the technical field of needle-punched felt, in particular to a trimming device for producing ultra-fine cotton needle-punched felt. Background Art

[0002] In the fields of textiles, filtration, and environmentally friendly materials, ultra-fine cotton needle-punched felt, a high-performance fiber composite material, has attracted widespread attention and application due to its excellent filtration efficiency, good air permeability, and reusability. Ultra-fine cotton needle-punched felt is typically made from ultra-fine fibers processed through a special process. These fibers are interwoven through a needle-punching technique to form a felt with a three-dimensional mesh structure. This significantly enhances the overall strength and durability of the material while retaining the fibers' original excellent properties.

[0003] Some existing needle felt trimming devices lack an extrusion limiting mechanism when in use, and are unable to constrain the shearing part of the needle felt. As a result, shaking or deviation is likely to occur during the shearing process, thereby affecting the shearing accuracy and smoothness, resulting in burrs, wavy edges, and other phenomena, affecting the quality of the final product.

[0004] For example, the announcement number CN217296623U discloses a trimming device for needle-punched felt processing. The trimming device of this patent is provided with a felt cloth placing roller, a tensioning roller and a felt cloth winding mechanism. The felt cloth wrapped around the outer wall of the felt cloth placing roller is driven by the felt cloth winding mechanism to move along the tensioning roller. During the movement, the excess edge material of the felt cloth is cut by the trimming mechanism, and manual cutting of the edge material is no longer required, which saves manpower and improves cutting efficiency. The trimming mechanism is installed and fixed by an adjusting mounting frame. During the trimming process, the position of the cutting blade of the trimming mechanism can be adjusted according to the different thicknesses of the felt cloth to meet the needs of trimming processing of felt cloths of different thicknesses.

[0005] While this trimming device offers many advantages, some areas still warrant further optimization. Due to the lack of a direct squeeze limiter on the shearing area, the felt, especially thicker or softer felt, can wobble or shift during the shearing process due to uneven elasticity or tension. This can affect shearing accuracy and smoothness, resulting in burrs and wavy edges, impacting the quality of the final product.

[0006] Therefore, it is necessary to invent a cutting device for producing ultra-fine cotton needle felt to solve the above problems. Utility Model Content

[0009] The combination of positive and negative tooth bidirectional modules and electric push rods allows the position and height of the cutting component to be flexibly adjusted. This design can adapt to ultra-fine cotton needle-punched felt materials of different widths and thicknesses, improving the versatility and adaptability of the equipment.

[0010] Preferably, a No. 1 double-roller conveyor is installed at the top input end of the workbench, and a No. 2 double-roller conveyor is installed at the top output end of the workbench.

[0013] The control panel integrates the control of the cutting mechanism, electric push rod, drive motor and double-roller conveyor, making operation easier and improving the overall controllability and ease of use of the equipment.

[0014] Preferably, two tensioning roller groups are installed on the top of the workbench, and the two tensioning roller groups are symmetrically distributed about the cutting mechanism.

[0015] Two tensioning rollers are symmetrically distributed on both sides of the cutting mechanism, which can effectively adjust the tension of the needle felt and ensure the flatness and stability of the material during the cutting process.

[0016] Preferably, a waste discharge trough is provided on the top of the workbench, and the waste discharge trough is arranged directly below the positive and negative tooth bidirectional module.

[0017] The waste discharge chute is set to facilitate the collection of waste and debris generated during the cutting process, reducing the cleaning workload at the production site and keeping the working environment clean.

[0018] Preferably, a receiving groove is provided at the bottom of the workbench, and the bottom of the waste discharge trough is connected to the receiving groove.

[0025] 1. By designing and installing a matching combination of upper and lower pressing rollers, precise limit clamping of the cutting part of the needle felt is achieved.

[0036] In one aspect of this embodiment, a No. 1 double-roller conveyor 12 is installed at the top input end of the workbench 1, and a No. 2 double-roller conveyor 13 is installed at the top output end of the workbench 1. A control panel 14 is installed on one side of one of the support columns 2.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5 When using the utility model, first, one end of the ultra-fine cotton needle felt material to be cut is passed through the No. 1 double-roller conveyor 12, two tensioning roller groups 15 and the No. 2 double-roller conveyor 13 in sequence to ensure that the needle felt is flat and wrinkle-free. The pressure of the tensioning roller group 15 is properly adjusted to maintain appropriate tension in the needle felt during transportation. At this time, the cut part of the needle felt is placed directly above the lower pressure roller 11.

[0039] Use the control panel 14 to operate the forward and reverse bidirectional module 3, adjust the positions of the two cutting assemblies 5 so that they are aligned with the cutting part of the needle felt, start the electric push rod 4, and move the two cutting assemblies 5 downward at the same time until the upper pressing roller 10 and the lower pressing roller 11 limit the clamping of the cutting part of the needle felt. Adjust the thrust of the electric push rod to ensure that the clamping force is moderate, which will not affect the conveying of the needle felt and can effectively prevent shaking or deviation during cutting;

[0040] The drive motor 8 is started to drive the cutting blade 7 to rotate and cut. During the cutting process, the control panel 14 is used to start the first double roller conveyor 12 and the second double roller conveyor 13 to keep the needle felt continuously conveyed, thereby achieving a continuous trimming operation of the needle felt.

[0041] The debris and waste generated during the cutting process will fall into the collection frame 17 below through the waste discharge chute 16. After the cutting is completed, the collection frame 17 is taken out and the waste therein is cleaned.
