Description

Technical Field

[0001] This invention belongs to the field of soft fabric processing technology, specifically relating to an automated forming jig and processing method for round soft fabrics used in products such as windproof and noise-reducing pom-poms and decorative pom-poms for lapel clip wireless microphones. Background Technology

[0002] Currently, products such as windproof and noise-canceling pom-poms (commonly known as "sweaters") used in lavalier wireless microphones, as well as decorative pom-poms, are mainly produced by hand-sewing. This production method has the following significant problems: 1. High technical difficulty and poor product consistency: Hand sewing requires a high level of skill from the operators. Products sewn by different workers, or even by the same worker at different times, will vary in shape, size, and tightness, resulting in unstable product quality.

[0003] 2. Low production efficiency and limited capacity: Hand-sewing is slow and is a labor-intensive industry. Especially during seasonal surges in market demand, it is difficult to quickly expand production capacity to meet delivery requirements.

[0004] 3. High production costs: It requires a large number of skilled workers, resulting in high labor costs. Furthermore, skilled workers have high turnover rates and are difficult to recruit.

[0005] 4. Limitations on the material of the central support: Traditional hand-sewing methods make it difficult to thread through hard, fragile plastic central supports, and usually only softer silicone parts can be used, which limits the variety of product shapes and appearances.

[0006] Therefore, there is an urgent need for a method and equipment that can achieve automated, standardized, and efficient production of such round soft fabric products. Summary of the Invention

[0007] The purpose of this invention is to provide a circular soft fabric processing fixture and processing method, which solves the problems of low production efficiency, poor product consistency, high cost, and limitations on the material of the central support in the prior art of manual sewing.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention is a circular soft fabric processing fixture, used to quickly shape circular fleece fabric from a planar state into a hollow hemispherical three-dimensional structure. It includes six core components: a base plate, a rotating shaft, a conical guide, a fleece pressing component, an adhesive size limiting component, and a vertical pole. All components are coaxially assembled, precisely positioned, and easy to assemble and disassemble.

[0009] The base plate provides stable support for the overall fixture and is made of hard aluminum alloy or engineering plastic with a flat and non-deformable surface.

[0010] A fixing block is fixedly installed on the left side of the upper surface of the base plate. A funnel-shaped insertion hole is opened in the center of the upper surface of the fixing block. The diameter of the hole is precisely matched with the lower end of the rotating shaft to realize the centering and free rotation of the rotating shaft.

[0011] The base plate has an installation hole on the right side of its upper surface for plugging and unplugging the pole. The hole depth is moderate to ensure that the pole is vertical and does not wobble.

[0012] The rotating shaft is the core rotating and positioning component of the fixture, and it is made of wear-resistant stainless steel.

[0013] The upper center of the rotating shaft is fixed with a positioning pin, preferably with a diameter of 0.5mm, which fits precisely with the positioning hole at the center of the fabric to ensure that the fabric is not eccentric.

[0014] The lower end of the rotating shaft is fitted with a funnel-shaped insertion hole with a gap, resulting in low rotational resistance and enabling the upper component to rotate at a uniform speed, ensuring uniform curing of the UV adhesive.

[0015] The tapered guide provides coaxial guidance for the fabric and the embossed part, and is made of a smooth, rigid material.

[0016] The tapered guide has a guide hole in the middle, which slides with the rotating shaft, allowing it to be quickly put on and taken off.

[0017] The outer cone angle of the tapered guide is matched with the inner guide cone groove of the embossing part to ensure that the fabric is compressed evenly, wrinkled evenly, and enters the embossing cavity without deviation.

[0018] The pressing component is the core component for shaping the fabric, and it is integrally formed by the guiding pressing component and the finishing pressing component.

[0019] The guide groove inside the embossed part is precisely fitted with the outer conical surface of the conical guide to achieve dual axial and radial positioning.

[0020] The pressing part has a through hole inside, which is connected to the guide cone groove. Multiple strip grooves are uniformly machined along the axial direction on the inner wall of the through hole, and the groove wall is mirror-polished smoothly.

[0021] The guide cone groove, through hole, and strip groove together form the embossing cavity, and the cavity size matches the inner diameter of the target product. The strip groove is used to accommodate the fabric fluff, so that the fluff is physically isolated from the glue application area, avoiding the UV glue from sticking to the fluff and the curing high temperature from burning the fluff, and maintaining the fluffy and intact appearance of the finished product.

[0022] The inner wall of the finishing press has a gear-shaped structure, and the strip grooves are evenly distributed along the circumference to ensure that the fabric is subjected to uniform force and the cylinder is shaped and regular.

[0023] The dispensing size limiting component is used to precisely limit the dispensing width and position, ensuring that the annular adhesive ring is uniform and consistent.

[0024] The lower half of the dispensing size limiting component is hollowed out into a cylindrical groove, which moves and fits with the upper part of the rotating shaft without affecting the rotation.

[0025] The upper half of the dispensing size limiting component has a movable through hole for the upper end of the upright to pass through in order to assist in demolding.

[0026] The dispensing size limiting component and the opening end of the finishing pressing component are arranged opposite to each other, forming an annular dispensing groove between them. The groove width is preferably about 1.4mm, which just exposes the edge of the bottom fabric to avoid glue overflow, while ensuring the balance of the strength and elasticity of the rubber ring.

[0027] The upright is an auxiliary demolding component and adopts a rigid straight rod structure.

[0028] The lower end of the upright is inserted into the mounting hole of the base plate for fixation, and the upper end has a receiving groove to cooperate with the positioning pin of the rotating shaft to ensure coaxiality.

[0029] During demolding, the fabric with adhesive applied and the rotating shaft are pushed upwards, allowing the adhesive size limiter to retract downwards, thus demolding the fabric.

[0030] A method for processing circular soft fabric, implemented using the aforementioned fixture, includes the following steps: Step 1: Fabric laser pretreatment Long-pile or short-pile soft fabric is precisely cut into circular fabrics of a preset diameter using a laser cutting machine; at the same time, a positioning hole with a diameter of 0.5mm is laser-processed at the center of the fabric circle. The hole is burr-free and does not damage the pile, ensuring the subsequent centering accuracy.

[0031] Step 2: Fixture assembly and fabric clamping and shaping 1. Insert the tapered guide piece from top to bottom along the rotation axis until it fits the fixing block.

[0032] 2. Take a circular piece of fabric, insert the positioning pin at the top of the rotating shaft from the pile side and out from the bottom fabric side to accurately position the center of the fabric.

[0033] 3. Insert the embossed part and the glue size limiter in sequence, and slowly press down to make the fabric fully enter the embossed cavity.

[0034] 4. Under the action of conical guide and cavity constraint, the planar circular fabric is uniformly compressed and shaped into a regular cylindrical shape, and the bottom edge of the fabric accurately reaches the opening end of the cavity, with uniform folds and no deviation.

[0035] Step 3: Positioning and injecting adhesive into the annular dispensing groove The lower end of the adhesive size limiting component is fitted onto the upper end of the rotating shaft, forming a stable and uniformly wide annular adhesive groove with the opening end of the pressing component. The rotating drive mechanism (electric or manual) is activated, causing the rotating shaft to drive the tapered guide, the pressing component, the adhesive size limiting component, and the fabric to rotate synchronously and uniformly. Using an automatic dispensing valve or a manual dispensing syringe, UV adhesive is injected uniformly along the annular dispensing groove. The adhesive adheres only to the edge of the base fabric, avoiding contact with the nap, ensuring a uniform and controllable dispensing amount.

[0036] Step 4: Rotary drive and rapid curing of UV adhesive 1. Restart the rotary drive mechanism to make the rotary shaft drive the tapered guide, the embossed part, the glue dispensing size limit part and the fabric to rotate synchronously and uniformly.

[0037] 2. Fix the UV curing lamp to the outside of the dispensing tank, keep the irradiation distance constant, turn on the light for 3-5 seconds, and the UV adhesive will quickly cure to form a highly elastic ring.

[0038] 3. Rotation curing ensures consistent thickness and uniform elasticity of the rubber ring in the circumferential direction, providing stable shrinkage force for subsequent self-shrinking molding.

[0039] Step 5: Assisted demolding and automatic shrink molding 1. First, pull the lower end of the rotating shaft out of the funnel-shaped insertion hole of the fixed block, and then place the lower end of the rotating shaft vertically against the base plate; 2. Forcefully remove the guide and crimping parts from the lower end of the rotating shaft. The glued fabric remains between the glued size limiter and the rotating shaft. Turn the rotating shaft, glued size limiter, and fabric over together. Pass the upper end of the upright through the movable through hole of the glued size limiter, with the top end abutting against the end face of the rotating shaft.

[0040] 3. Keep the upright fixed, push the glue dispensing size limit piece downwards simultaneously, remove the glue dispensing size limit piece, and the fabric will be demolded.

[0041] 4. After demolding, the fabric automatically flips inward and shrinks evenly under the uniform elastic shrinkage force of the ring rubber ring, forming a hollow hemispherical fleece with stable dimensions, high sphericity, and fluffy appearance in one go.

[0042] Step 6: Filling and assembling the central support 1. Fill the hollow hemispherical fur ball with sound-absorbing cotton, fluffy cotton and other filling materials to make the fur ball full and three-dimensional.

[0043] 2. Apply structural adhesive to the surface of the central support, insert the support into the central positioning hole of the sleeve, and let it stand until the structural adhesive is completely cured.

[0044] 3. The final product is a microphone windproof pom-pom or decorative pom-pom; the central support can be made of various materials such as silicone, soft plastic, and hard plastic, and is compatible with supports of different diameters and structures, so as to realize flexible co-line production of products of various specifications.

[0045] The present invention has the following beneficial effects: 1. Replaces hand sewing, enabling automated and standardized production. The process of using jigs for shaping, glue application and curing, and automatic shrinkage molding completely replaces traditional hand sewing, eliminating reliance on skilled workers. The product has extremely high consistency in appearance, size and tightness, and the quality is stable and controllable.

[0046] 2. Significantly improve production efficiency and reduce production costs. The process is simplified and can be quickly batch-produced, significantly shortening the processing cycle of a single product and allowing production capacity to be flexibly increased according to market demand; it reduces labor input, significantly lowers labor costs, and solves the problems of difficulty in recruiting workers and high worker turnover.

[0047] 3. Protects the integrity of the pile, resulting in a better appearance of the finished product. The embossing cavity has a strip groove to physically contain the fluff, allowing the UV adhesive to adhere only to the edge of the base fabric. This prevents the adhesive from sticking to the fluff and the high temperature of curing from burning the fluff. The finished product has a fluffiness and appearance integrity that far exceed that of handmade products.

[0048] 4. Compatible with center supports of various materials and specifications, offering strong adaptability. Breaking through the limitations of traditional handcrafting which can only accommodate soft silicone supports, it is compatible with supports made of various materials such as silicone, soft plastic, and hard plastic, and can adapt to supports of different sizes and structures, enabling flexible co-production of products of various specifications on the same production line.

[0049] 5. Precise and stable molding, high process reliability. Relying on the design of conical guide, coaxial positioning, and rotation curing, the fabric is shaped without wrinkles, offset, or stretching. The ring rubber ring has uniform elasticity and automatically shrinks into a regular hollow hemispherical sleeve after demolding, with high sphericity and stable dimensional accuracy.

[0050] 6. Simple and easy-to-use structure, suitable for mass production. The fixture is assembled coaxially from six core components, making it easy to disassemble and assemble with a low operating threshold. It can be paired with automatic dispensing and rotary curing equipment to achieve semi-automatic / fully automated production lines, making it suitable for industrial mass production.

[0051] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0058] Example 1 Please see Figures 1-4 As shown, the present invention is a circular soft fabric processing fixture for processing circular soft fabric into a three-dimensional shape, including a base plate 1, a rotating shaft 2, a conical guide 3, a embossing part 4, an adhesive dispensing size limiting part 5, and a vertical rod 6.

[0059] A fixing block 101 is fixed to the left side of the upper surface of the base plate 1. A funnel-shaped insertion hole 102 matching the rotating shaft 2 is opened in the middle of the upper surface of the fixing block 101. An installation insertion hole 103 is provided on the right side of the upper surface of the base plate 1, and a vertical rod 6 is inserted into the installation insertion hole 103. A receiving groove 601 is opened at the upper end of the vertical rod 6.

[0060] The upper end of the rotating shaft 2 is fixed with a positioning pin 201 that matches the receiving groove 601. The tapered guide 3, the embossing part 4, and the glue dispensing size limiting part 5 are sequentially sleeved on the circumferential side of the rotating shaft 2.

[0061] The tapered guide 3 has a guide hole 301 in the middle that matches the rotating shaft 2.

[0062] The embossing component 4 is integrally formed from a guide embossing component 401 and a finishing embossing component 402. The guide embossing component 401 has a guide conical groove 403 in its center that matches the conical guide component 3. The finishing embossing component 402 has a through hole 404 in its center that communicates with the guide conical groove 403. The inner wall of the through hole 404 is machined with an axially extending strip groove 405. The guide conical groove 403, the through hole 404, and the strip groove 405 on the inner wall together form the embossing cavity. The inner wall of the finishing embossing component 402 has a gear-shaped structure, and the strip grooves 405 are evenly distributed along the circumference and have undergone smooth polishing.

[0063] The lower end of the adhesive dispensing size limiting member 5 has a groove 501 that matches the rotating shaft 2, and a movable through hole 502 that matches the upright 6 is formed in the groove 501. The adhesive dispensing size limiting member 5 and the opening end of the finishing pressing member 402 are arranged opposite to each other, forming an annular adhesive dispensing groove 503 for exposing the edge of the fabric base. In this embodiment, the width of the annular adhesive dispensing groove 503 is preferably 1.4 mm.

[0064] Example 2 This embodiment provides a method for processing circular soft fabric using the above-mentioned fixture, and the specific steps are as follows: Step 1: Fabric Pretreatment The fleece fabric is precisely cut into circular pieces of a preset diameter using a laser cutting machine. At the same time, a positioning hole with a diameter of 0.5mm is laser-processed at the center of the fabric. The hole is burr-free and does not damage the fleece.

[0065] Step 2: Fixture assembly and fabric clamping and shaping Insert the tapered guide 3 along the rotating shaft 2 from top to bottom until it fits against the fixing block 101. Take a circular piece of fabric and insert the positioning pin 201 at the top of the rotating shaft 2 from the pile side to the bottom fabric side to accurately position the center of the fabric. Then, insert the embossing part 4 and the glue dotting size limiter 5 in sequence, and slowly press down to allow the fabric to fully enter the embossing cavity. Under the constraint of the tapered guide and the cavity, the flat circular fabric is uniformly compressed and shaped into a regular cylindrical shape, with the bottom fabric edge accurately reaching the opening end of the cavity. During this process, the strip groove 405 of the embossing cavity accommodates the fabric pile, preventing the subsequent UV glue from contacting the pile.

[0066] Step 3: Positioning and injecting adhesive into the annular dispensing groove The lower end of the adhesive dispensing size limiting component 5 is fitted onto the upper end of the rotating shaft 2, forming a stable and equally wide annular adhesive dispensing groove 503 with the open end of the finishing pressing component 402. The rotating shaft 2 is manually rotated synchronously to drive the tapered guide component 3, the pressing component 4, the adhesive dispensing size limiting component 5, and the fabric. Using an automatic dispensing valve or a manual dispensing syringe, UV adhesive is injected at a uniform speed along the annular adhesive dispensing groove 503, with the adhesive only adhering to the edge of the base fabric.

[0067] Step 4: Rotary drive and rapid curing of UV adhesive Manually rotate shaft 2 again to drive the conical guide 3, the embossing part 4, the dispensing size limit part 5, and the fabric to rotate synchronously. Fix the UV curing lamp to the outside of the annular dispensing groove 503, maintain a constant irradiation distance, and turn on the light for 3-5 seconds. The UV adhesive will quickly cure to form a highly elastic annular adhesive ring. Rotation curing ensures that the thickness of the adhesive ring is consistent and the elasticity is uniform in the circumferential direction.

[0068] Step 5: Assisted demolding and automatic shrink molding First, pull the lower end of the rotating shaft 2 out of the funnel-shaped insertion hole 102 of the fixing block 101. Then, vertically press the lower end of the rotating shaft 2 against the base plate 1. Next, forcefully remove the tapered guide 3 and the pressing part 4 from the lower end of the rotating shaft 2. The glued fabric remains between the glued size limiting part 5 and the rotating shaft 2. Turn the rotating shaft 2, the glued size limiting part 5, and the fabric over together. Pass the upper end of the upright 6 through the movable through hole 502 of the glued size limiting part 5, so that the top receiving groove 601 abuts against the positioning pin 201 of the rotating shaft 2. Simultaneously push the glued size limiting part 5 downward to remove the glued size limiting part 5 and complete the demolding. After demolding, the fabric automatically flips inward and shrinks evenly under the uniform elastic contraction force of the annular rubber ring, forming a hollow hemispherical fleece with stable dimensions, high sphericity, and a fluffy appearance in one go.

[0069] Step 6: Filling and assembling the central support Fill the hollow hemispherical pom-pom with sound-absorbing cotton or fluffy cotton to make the pom-pom full and three-dimensional. Apply structural adhesive to the surface of the central support (which can be a silicone part, a soft plastic part, or a hard plastic part), insert the support into the central positioning hole of the pom-pom, and let it stand until the structural adhesive is completely cured to obtain the final product of microphone windproof pom-pom or decorative pom-pom.
