Description

Technical Field

[0001] This utility model relates to the field of fabric processing machinery technology, specifically a fabric burr trimming mechanism. Background Technology

[0002] In the manufacturing and processing of textiles and finished fabrics, exposed threads and burrs are common problems at the edges of fabrics due to cutting, sewing, or transportation. This not only affects the appearance quality of the finished product but may also cause problems such as unraveling and breakage during subsequent use, and in severe cases, it can reduce the product grade or require rework. Therefore, efficient trimming of threads and burrs at the edges of fabrics has become an indispensable process in the textile industry.

[0003] Currently, the most common fabric burr trimming tools in the industry can be categorized as follows:

[0004] Manual shear-type trimming tools: These tools are simple to operate and easy to trim by hand, but they have low cutting efficiency and the cutting quality is highly dependent on human experience, resulting in poor consistency and low efficiency.

[0005] Electric rotary trimming equipment: This type of device usually uses a motor to drive a rotating blade to cut the fabric edge. Although it can achieve continuous cutting, due to the complex gear or motor transmission components involved in the structure, the following problems exist: complex structure, high failure rate, and frequent maintenance; fixed blade rotation direction, poor adaptability to fabric edges with different orientations; large mechanical noise generated by the motor operation, and vibration affecting operational stability.

[0006] Some products suffer from low cutting precision, especially when dealing with fine structures like fiber ends, resulting in "missed cuts" or "broken cuts." Therefore, this paper researches and improves upon existing technologies to provide a fabric burr trimming mechanism, aiming to solve current problems and enhance practical value. Summary of the Invention

It has a reasonable structure and high cutting efficiency, and can perform high-frequency and stable cutting of fabric edge threads and burrs, thereby improving the cleanliness of the fabric edges. It is suitable for textile post-processing scenarios.

[0008] This utility model provides a fabric burr trimming mechanism, comprising a handle, a trimming assembly, and a guide. The handle is a handheld structure, internally equipped with an electromagnetic coil and a fixedly mounted shaft. A swing head is movably mounted on the shaft, sleeved on the shaft surface, and can reciprocate around the shaft. Springs are symmetrically mounted on both sides of the swing head and connected to the inner wall of the handle to provide a restoring elastic force. A permanent magnet is mounted at one end of the swing head, driven by the alternating magnetic field of the electromagnetic coil to achieve high-speed reciprocating motion. The trimming assembly includes a fixed fixed shear head, a slidingly fitted movable shear head, and a pressure head seat connected to the handle at one end. A shear head rod is connected to one side of the movable shear head 220, and this rod structure is inserted into the V-shaped shear groove of the fixed shear head to achieve a shearing engagement. The guide includes a guide seat and rollers symmetrically arranged at its two ends. A clamping rod is fixedly connected to one side of the guide seat, and the rollers are rotatably mounted on the surface of the clamping rod.

[0009] Technical benefits: This structural design can achieve stable shearing action through electromagnetic excitation, providing precise guidance and convenient operation, making it suitable for quickly cleaning burrs on the edges of fabrics.

[0010] In a preferred embodiment, the present invention can be further configured such that: the end of the electromagnetic coil is electrically connected to a control switch, which is embedded in the grip surface, so that the user can operate the electromagnetic drive system with one hand to turn it on / off;

[0011] The handle features an ergonomic grip groove structure on its outer contour and anti-slip ridges on the surface, enhancing grip comfort and anti-slip performance.

[0012] Technical benefits: It can improve the operational stability and comfort of the equipment during long-term use and reduce the risk of misoperation.

[0013] In a preferred embodiment, the present invention can be further configured such that the scissor head has a V-shaped scissor groove and its edge is provided with a precision cutting edge;

[0014] The cutting head bar on the moving head slides into contact with the blade surface of the cutting groove, forming a cutting structure that can stably guide the wire end into the cutting zone and achieve precise cutting.

[0015] Technical benefits: Improves shearing alignment accuracy and cutting smoothness, and reduces residual burrs.

[0016] In a preferred embodiment, the present invention can be further configured such that: the pressure head seat is a flexible metal component with an overall arc-shaped structure, one end of which is fixedly installed at the end of the handle, and the other end slides against the surface of the moving shear head to provide shearing and bonding force. This structure can automatically adjust the bonding strength according to the operation of the shear head.

[0017] Technical effect: Significantly reduces the gap between the moving and stationary shear heads, improving shearing efficiency and uniformity.

[0018] In a preferred embodiment, this invention can be further configured such that the width of the end of the cutting bar is smaller than the width of the cutting groove entrance, so that when the fabric edge thread or burr enters, it can be smoothly guided into the cutting area, avoiding jamming or omission.

[0019] Technical effect: Improves the efficiency of introducing and cutting small burrs or tiny thread ends.

[0020] In a preferred embodiment, this utility model can be further configured as follows: the clamping rods are symmetrically arranged at both ends of the guide seat and are made of elastic material; two rollers are rotatably mounted on the clamping rods through bushings, and when the fabric is placed into the clamping gap, an elastic clamping force is formed between the two rollers to ensure that the fabric adheres to the surface during the guiding process.

[0021] Technical effect: Improves the stability of fabric guidance and avoids shearing deviation caused by slippage.

[0022] In a preferred embodiment, this utility model can be further configured such that: after the oscillating head is energized by the electromagnetic coil, a magnetic field force is formed between it and the permanent magnet, causing the oscillating head to reciprocate on the shaft; the oscillation action is transmitted through the movable connection structure between one end of the oscillating head and the movable shear head, driving the movable shear head to perform high-frequency sliding shearing on the surface of the fixed shear head.

[0023] Technical benefits: High-frequency reciprocating motion of the shearing component can be achieved without complex mechanical transmission, simplifying the structure and reducing energy consumption.

[0024] The beneficial effects achieved by this utility model are as follows:

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0037] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0038] The following is in conjunction with the appendix Figures 1-5 This invention describes a fabric burr trimming mechanism provided by some embodiments of the present invention. Example 1:

[0039] like Figures 1 to 5 As shown, this utility model provides a fabric burr trimming mechanism, including a handle 100, a trimming component 200, and a guide 300 fixedly disposed at one end of the handle 100.

[0040] The grip 100 is a handheld structure with an ergonomic design. Its surface is provided with grip grooves and anti-slip ridges to improve grip stability. An electromagnetic coil 110 is installed inside the grip 100, and a shaft 101 is fixedly installed along the central axis.

[0041] A sway head 120 is sleeved on the outer side of the shaft 101, and the sway head 120 can reciprocate around the shaft 101. Springs 121 are symmetrically arranged on both sides of the sway head 120. One end of each spring 121 is connected to the sway head 120, and the other end is fixed to the inner wall of the handle 100 to provide a restoring force. A permanent magnet 130 is installed at one end of the sway head 120, which drives the sway head 120 to oscillate at high frequency through interaction with the on / off magnetic field of the electromagnetic coil 110.

[0042] The trimming assembly 200 includes a fixed shear head 210, a movable shear head 220, and a pressure head seat 230. The pressure head seat 230 is an elastic metal component with an arc-shaped structure. One end is fixed to the end of the handle 100, and the other end abuts against the surface of the movable shear head 220. The pressure head seat 230 provides elastic clamping force and also guides the movable shear head 220 to slide.

[0043] The movable shear head 220 is slidably connected to the surface of the fixed shear head 210. The fixed shear head 210 has a V-shaped cutting groove 211 on its surface, and its edge has a cutting edge. The movable shear head 220 slides against the cutting groove 211 through a shear rod 221 provided on its side, thereby forming a shearing structure. When the swing head member 120 drives the movable shear head 220 to slide back and forth, burrs and thread ends can be cut and removed within the cutting groove 211. The end width of the shear rod 221 is smaller than the port width of the cutting groove 211, so that thread ends and burrs can enter the working area inside the cutting groove 211.

[0044] The guide 300 includes a guide seat 310 and rollers 320 symmetrically arranged at both ends thereon. A clamping rod 311 is fixedly connected to one side of the guide seat 310. The clamping rod 311 is an elastic structure that can elastically clamp the edge of the fabric. The rollers 320 are installed at the ends of the clamping rod 311. By rolling the edge of the fabric, the burrs are smoothly guided into the shearing zone.

[0045] When in use, the operator holds the handle 100 and aligns the guide 300 with the edge of the fabric. The roller 320 rolls on the surface of the fabric, guiding the edge thread into the cutting groove 211 area. After being powered on, the electromagnetic coil 110 generates a magnetic field, which drives the permanent magnet 130 and the swing head 120 to reciprocate, thereby driving the moving cutter head 220 to slide along the surface of the fixed cutter head 210 and form a shearing action with the cutting groove 211, achieving efficient trimming of thread ends and burrs.

[0046] Through the combination of the above structure and actions, the overall device has the advantages of compact structure, simple operation and high cutting accuracy, and is particularly suitable for thread trimming in the post-processing of textile fabrics. Example 2:

[0047] In this embodiment, the overall structure is basically the same as that in Embodiment 1. The main difference is that the guide 300 adopts a modular design, and the roller 320 can be installed on the clamp rod 311 through a quick-release buckle structure, which makes it easy to replace rollers of different materials and sizes according to different fabric thicknesses, thereby adapting to the edge shape of different fabrics.

[0048] In addition, the fixed shear head 210 in this embodiment has a nano-level anti-adhesion coating on its surface to reduce fiber adhesion during shearing, improve shearing smoothness, and extend the service life of the component.

[0049] The cutting rod 221 of the moving cutting head 220 is made of high-strength alloy material, and its end width is precisely smaller than the entrance width of the cutting groove 211, which can effectively guide the thread end into the cutting groove and avoid accidentally damaging the fabric.

[0050] In addition to providing elastic clamping force, the pressure head seat 230 has an adjustable curvature angle, which makes it easy to adapt to moving shear heads 220 of different lengths and realize more customized use scenarios.

[0051] In terms of operation, the operator still holds the handle 100, aligns the guide 300 with the edge of the fabric to be trimmed, and the roller 320 guides the thread end through the cutting groove 211 into the cutting area. After the electromagnetic coil 110 is energized, the swing head 120 is excited to generate reciprocating motion, thereby driving the moving cutter head 220 and the stationary cutter head 210 to form a high-frequency cutting action, achieving burr removal. It is particularly suitable for trimming needs of fabrics of different thicknesses or with more complex edges.

[0052] Supplementary Explanation

[0053] This utility model can also be modified in various ways according to actual needs, such as the slide rail telescopic form of the guide structure, the multi-angle adjustable design of the cutter head combination module, and the frequency modulation and amplitude modulation control of the electromagnetic drive structure. These modifications do not exceed the spirit and scope of protection of this utility model and the claims.

[0054] Working principle and usage process of this utility model:

[0055] In use, the fabric burr trimming mechanism of this invention involves holding the handle 100 to guide the guide 300 towards the edge of the fabric and pushing the device along the edge. During this pushing process, the roller 320 rolls forward in contact with the edge of the fabric, achieving stable guidance of the trimming path.

[0056] During the rolling process, loose threads and burrs from the fabric edge are drawn into the inner side of the cutting groove 211 on the surface of the fixed shear head 210. This cutting groove has a V-shaped structure and serves as a limiting and guiding function, accurately guiding the burrs into the shearing working area.

[0057] When the device is powered on, the electromagnetic coil 110 built into the inside of the handle 100 and the permanent magnet 130 generate an electromagnetic driving force, causing the oscillating head component 120 to reciprocate at a high frequency on the fixed shaft 101. Since one end of the oscillating head component 120 is movably connected to the surface of the moving cutter head 220, this reciprocating oscillation drives the moving cutter head 220 to reciprocate synchronously on the surface of the fixed cutter head 210.

[0058] During the sliding process, a shearing action is formed between the moving shear head 220 and the fixed shear head 210, especially through the surface contact between the shear head rod 221 and the V-shaped shear groove 211, which achieves efficient shearing of burrs and thread ends entering the working area.

[0059] In addition, the pressure head seat 230 set on the moving shear head 220 has an elastic pressing function, which can effectively reduce the gap between the shear heads and improve the cutting accuracy.

[0060] The entire process requires no complicated operation. The operator only needs to steadily push the device along the edge of the fabric to achieve fast and accurate burr trimming, improving the cleanliness and aesthetics of the fabric edge. It is suitable for scenarios such as garment processing and post-cut fabric finishing.
