Description

Technical Field

[0001] This invention relates to the field of fabric winding technology, and more particularly to a nonwoven fabric winding mechanism for nonwoven fabric processing equipment. Background Technology

[0002] Nonwoven fabric, a new type of fiber product made by directly arranging and binding fibers together in a directional or random manner through physical or chemical methods without traditional spinning and weaving processes, has been widely used in many fields such as medical and sanitary materials, home decoration, clothing accessories, agricultural coverings, and industrial wiping due to its outstanding advantages such as short production process, relatively low cost, and high plasticity. With the continuous upgrading and segmentation of the consumer market, the requirements for the appearance and function of nonwoven fabric products are also increasing.

[0003] In order to enhance the aesthetics and added value of products, various patterns are processed on the edges of non-woven fabrics, especially scallop-shaped lace that imitates the natural form, which has become a common post-processing technique.

[0004] When using traditional winding mechanisms to process nonwoven fabrics with scalloped lace, the following problems arise: uneven winding and edge bulging. The scalloped lace is not a straight edge, but rather consists of continuous curved protrusions and indentations. During winding, the flat fabric portion can be evenly stretched and wound, but due to its non-linear geometry, the lace portion experiences uneven stress at different points under the same tension. The crests are relatively easy to stretch and wind up, while the troughs tend to remain slack due to a lack of effective radial constraint.

[0005] This slackness prevents the lace from adhering tightly to the inner layer during winding, unlike a flat selvage. With each turn, the loose lace accumulates slightly. As the number of winding layers increases, this accumulation amplifies, causing the diameter of the lace area at both ends of the roll to be significantly larger than the diameter of the flat fabric area in the middle, resulting in a non-cylindrical roll that is bulging at both ends and concave in the middle. This irregular shape is not only unsightly but, more importantly, causes serious problems in subsequent processes. The folded lace itself may also develop permanent creases, affecting the final product's appearance. Summary of the Invention

[0006] This application provides a nonwoven fabric winding mechanism for nonwoven fabric processing equipment, solving the problem in the prior art where, when conventionally winding nonwoven fabric with lace trim, the lace trim, being not straight, tends to expand during winding due to lack of tension, resulting in a non-cylindrical shape after winding and causing problems for subsequent transportation. The mechanism achieves this by having multiple rotating rods arranged in a C-shape around the outside of the roll, constantly pressing against the outermost layer of the fabric roll during winding. This provides continuous radial pressure to the uneven lace trim, forcing it to wrap snugly around the roll, effectively preventing the lace trim from uncomfortably unraveling and avoiding edge expansion. A guide plate positioned above the multiple rotating rods has its beveled edge that first contacts and catches the moving nonwoven fabric lace trim. The beveled edge acts as a smooth transition surface, guiding any folded or sagging lace trim to a flat state.

[0007] This application provides a nonwoven fabric winding mechanism for a nonwoven fabric processing equipment, including a winding assembly, which includes an expansion member, an adjustment member, and a roll. The expansion component includes a rotating rod; The adjusting components include a guide plate and a bevel; There are multiple expansion components, and the rotating rods inside the multiple expansion components are arranged in a C-shape on the outer ring of the drum. The opening of the C-shaped rotating rods is located above the drum. The rotating rod is used to press the non-woven fabric, and the drum is used to wind up the non-woven fabric. The non-woven fabric is wound between the rotating rod and the drum. The guide plate is positioned above the topmost rotating rod, and a bevel is formed on one side of the guide plate; The end of the guide plate away from the inclined side is located at the opening of the rotating rod, which is set in a C-shape. During winding, the nonwoven fabric is placed above the guide plate, with the slanted edge of the guide plate abutting against the scalloped lace of the nonwoven fabric; The winding assembly also includes a base plate, a vertical plate, and a mounting plate; The upright plate is installed on the base plate, and the mounting plate is cylindrical and fixed to one side of the upright plate; The expansion components also include an electric slide, a motor, and a mounting rod; Multiple electric sliding tables are fixed in a C-shape at even intervals on one side of the mounting plate; Motor 1 is fixed on the slider of the electric slide table, and the mounting rod is fixed to the output end of motor 1; The rotating rod is fixed at the end of the mounting rod furthest from the motor.

Motor 2 is fixed to one side of the mounting plate, and Motor 2 is located at the center of multiple expansion components; One end of the rotating drum is rotatably connected to a rotating rod, and the end of the rotating drum away from the rotating rod is fixedly connected to a fixing rod. The fixing rod at one end of the rotating drum is fixed to the second output end of the motor. The rotating drum, rotating rod, and fixed rod are all cylindrical, and the axis of the rotating drum, the axis of the rotating rod, and the axis of the fixed rod are on the same straight line as the rotation axis of the two output ends of the motor. There are multiple telescopic poles and multiple contact balls, and they correspond one-to-one. The telescopic rod is in the shape of a ring and is arranged in an array along the axis of the rotating cylinder, with the abutment ball fixed at the output end of the telescopic rod. The ball is made of rubber. The drum is sleeved on the rotating drum, and the contact ball abuts against the inner wall of the drum; The lower end of the telescopic rod is fixed to the base plate, and the placement frame is V-shaped and fixed to the output end of the telescopic rod. Telescopic rod two is located on the same side of the mounting plate that fixes motor two; In the initial state, the rotating rod is placed on the mounting bracket.

[0010] As an improvement, when winding up the nonwoven fabric, the rotation direction of the roll is opposite to that of the rotating rod; When winding up nonwoven fabric, the linear velocity of the outermost ring of the roll and the surface of the rotating rod are the same.

[0011] As an improvement, the adjusting components also include mounting plate one, mounting plate two, telescopic rod three, fixing plate, connecting plate and lifting plate; Mounting plate one is fixed to the base plate, mounting plate two is fixed to the side of mounting plate one near the drum, mounting plate two is located above the expansion member, and telescopic rod three is fixed to the lower side of mounting plate two. The fixing plate is fixed to the lower three sides of the telescopic pole; There are two connecting plates, which are fixed at both ends of the fixed plate along its length. The lifting plate is fixed between the two connecting plates, and the lifting plate is located below the fixed plate; The lower side of the lifting plate is always in close contact with the rotating rod inside the uppermost expansion member; A gap of five to ten centimeters is left between the lifting plate and the fixing plate.

[0012] As an improvement, the lifting plate is an electromagnet structure; The end of the guide plate away from the inclined side is made of iron. The iron material at one end of the guide plate is adsorbed onto the lifting plate of the electromagnet structure; There are multiple guide panels; When the nonwoven fabric is wound up, it passes through the gap between the fixed plate and the lifting plate.

[0013] As an improvement, an expansion assembly is also included, which comprises an air pump II and an airbag II; The number of airbags is the same as the number of guide plates, and they correspond one-to-one.

The output end of air pump 1 is connected to airbag 1.

[0015] As an improvement, when the nonwoven fabric passes through the gap between the fixed plate and the lifting plate, the airbag inflates and adheres to the upper side of the nonwoven fabric.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: Firstly, multiple rotating rods are arranged in a C-shape around the outside of the roll, pressing against the outermost layer of the fabric roll throughout the winding process. This provides a continuous radial pressure to the uneven lace, forcing it to wrap neatly around the roll and effectively preventing the lace from uncomfortably unraveling, thus avoiding edge swelling. The guide plate above the multiple rotating rods has its beveled edge that can first contact and catch the moving non-woven lace. The beveled edge acts as a smooth transition surface, guiding any lace that may fold or sag to a flat state. Secondly, the second airbag is set on the inclined side of the guide plate, and its periodic expansion and contraction are controlled by the second air pump; this reciprocating motion can shake and loosen those laces that are stuck together or folded, realizing dynamic and active sorting of the laces. Thirdly, to prevent the lace from curling up or flipping over, the pressing plate and the airbag below it are located above the nonwoven fabric before it enters the winding area. When the airbag inflates, it gently presses down on the upper surface of the nonwoven fabric, especially those laces that have curled up or flipped over onto the fabric surface, pushing them back to their normal position and ensuring effective straightening; whether the lace sags, curls up, or flips over, it can be effectively corrected.

[0019] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0020] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Example 1: As Figures 1-10 As shown, this application discloses a nonwoven fabric winding mechanism for nonwoven fabric processing equipment, including a winding assembly 100. The winding assembly 100 includes a base plate 110, a vertical plate 120, a mounting plate 130, an expansion member 140, a positioning member 150, an adjusting member 160, and a roll 170. The expansion member 140 includes an electric slide 141, a motor 142, a mounting rod 143, and a rotating rod 144; The adjusting component 160 includes mounting plate 161, mounting plate 2 162, telescopic rod 3 163, fixing plate 164, connecting plate 166, lifting plate 167, guide plate 168, and inclined side 169. There are multiple expansion members 140, and the rotating rods 144 inside the multiple expansion members 140 are arranged in a C-shape on the outer ring of the drum 170. The opening of the C-shaped rotating rods 144 is located above the drum 170. The rotating rod 144 is used to press the non-woven fabric, and the drum 170 is used to wind up the non-woven fabric. The non-woven fabric is wound between the rotating rod 144 and the drum 170. The drum 170 is a cylindrical shape that runs through its axis; The rotating rod 144 is cylindrical, and its axis is parallel to the axis of the drum 170. In the initial state, the outer ring of the rotating rod 144 is in contact with the outer ring of the drum 170.

[0023] When winding up the nonwoven fabric, the rotation direction of the roll 170 is opposite to the rotation direction of the rotating rod 144; When winding up the nonwoven fabric, the outermost ring of the roll 170 and the surface linear velocity of the rotating rod 144 are the same.

[0024] Specifically, during the winding operation, the non-woven fabric is wound onto the roll 170, and the rotating rod 144 always abuts against the outermost layer of the non-woven fabric on the roll 170. The scallop-shaped lace edge of the non-woven fabric is pressed and wrapped by the mutual clamping between the rotating rod 144 and the roll 170. Furthermore, when winding up the nonwoven fabric, the outermost ring of the roll 170 and the surface linear velocity of the rotating rod 144 are consistent, so as to avoid the nonwoven fabric from wrinkling or shifting due to inconsistent rotation speeds between the two during the rotation process. Furthermore, since the diameter of the nonwoven fabric wound on the drum 170 changes continuously when the drum 170 is winding up the nonwoven fabric, it is necessary to continuously adjust the rotation speed of the drum 170 or the rotating rod 144 to keep the linear velocity of the outermost ring of the drum 170 and the surface of the rotating rod 144 consistent.

[0025] The guide plate 168 is positioned above the uppermost rotating rod 144, and a bevel 169 is formed on one side of the guide plate 168; The end of the guide plate 168 away from the inclined side 169 is located at the opening of the C-shaped rotating rod 144; During winding, the nonwoven fabric is placed above the guide plate 168, and the inclined edge 169 of the guide plate 168 abuts against the scalloped lace of the nonwoven fabric.

[0026] Specifically, when winding the nonwoven fabric, the inclined edge 169 of the guide plate 168 abuts against the scallop-shaped lace at the edge of the nonwoven fabric, so that the scallop-shaped lace of the nonwoven fabric is gradually guided to the upper side of the guide plate 168, which can facilitate winding and avoid the scallop-shaped lace being folded together during the winding process, which would cause the edge to expand and the winding to deviate.

[0027] The upright plate 120 is installed on the base plate 110, and the mounting plate 130 is cylindrical and fixed to one side of the upright plate 120. Multiple electric slides 141 are fixed in a C-shape at even intervals on one side of the mounting plate 130; Motor 142 is fixed on the slider of electric slide table 141, and mounting rod 143 is fixed on the output end of motor 142; The rotating rod 144 is fixed to the end of the mounting rod 143 away from the motor 142; Specifically, when the electric slide table 141 drives the rotating rod 144 to move to the farthest point from the drum 170, the inner scallop arc width of the non-woven fabric scallop-shaped lace to be wound is smaller than the distance between two adjacent rotating rods 144; the inner scallop arc width of the non-woven fabric scallop-shaped lace refers to the straight-line distance between the scallop from one trough to the next; this can prevent the distance between adjacent rotating rods 144 from being too large when the rotating rod 144 gradually expands outward, which would prevent the non-woven fabric scallop-shaped lace from being unable to resist.

[0028] The rotation axis of the output end of motor 142 is on the same straight line as the axis of the corresponding rotating rod 144.

[0029] Specifically, when the roll 170 is winding up the nonwoven fabric, the diameter of the nonwoven fabric wound on the roll 170 is constantly changing. It is necessary to continuously adjust the distance between the rotating rod 144 and the outermost ring of nonwoven fabric on the roll 170 by the electric slide table 141. When winding up the next ring of nonwoven fabric, the gap of the expansion member 140 that first contacts the nonwoven fabric is adjusted, and the distance between the rotating rod 144 and the outermost ring of nonwoven fabric on the roll 170 is adjusted by the electric slide table 141 so that the distance can accommodate the new ring of nonwoven fabric for winding. After the first expansion member 140 that contacts the nonwoven fabric adjusts the gap, the subsequent expansion members 140 adjust the gap between themselves and the outermost ring of the roll 170 in turn to facilitate the winding of new nonwoven fabric.

[0030] During the winding of the nonwoven fabric, the nonwoven fabric is placed at the C-shaped points of multiple rotating rods 144 and adhered to the roll 170, as shown below. Figure 2 In the state shown, the nonwoven fabric is wound up by rotating the roll 170 clockwise.

[0031] The positioning component 150 includes a second motor 151, a rotating drum 152, a rotating rod 153, a first telescopic rod 154, a contact ball 155, a second telescopic rod 156, and a placement frame 157. Motor 2 151 is fixed to one side of mounting plate 130, and motor 2 151 is located at the center of multiple expansion parts 140; One end of the rotating drum 152 is rotatably connected to the rotating rod 153, and the other end of the rotating drum 152 away from the rotating rod 153 is fixedly connected to the fixing rod 158. The fixing rod 158 at one end of the rotating drum 152 is fixed to the output end of the motor 151. The rotating drum 152, rotating rod 153 and fixed rod 158 are all cylindrical. The axis of the rotating drum 152, the axis of the rotating rod 153 and the axis of the fixed rod 158 are on the same straight line as the rotation axis of the output end of the motor 151. There are multiple telescopic rods 154 and multiple contact balls 155, and they correspond one-to-one. The telescopic rod 154 is in the shape of a ring and is arranged in an array along the axis of the rotating cylinder 152. The contact ball 155 is fixed at the output end of the telescopic rod 154. The 155 contact ball is made of rubber. The drum 170 is sleeved on the rotating drum 152, and the contact ball 155 abuts against the inner wall of the drum 170; The lower end of the telescopic rod 156 is fixed on the base plate 110, and the placement frame 157 is V-shaped and fixed to the output end of the telescopic rod 156. Telescopic rod 2 156 is located on the same side of mounting plate 130 where motor 2 151 is fixed; In the initial state, the rotating rod 153 is placed on the placement rack 157.

[0032] Specifically, during the winding operation, the drum 170 is fitted onto the rotating drum 152, and the contact ball 155 is pressed against the inner wall of the drum 170 by the operation of the telescopic rod 154 to fix the position of the drum 170; the rotation of the motor 151 drives the drum 170 to rotate as a whole, and the height of the telescopic rod 156 can be raised to place the rotating rod 153 inside the placement frame 157 for support. After a single drum 170 completes its winding operation, the expander 140 is moved away from the drum 170, and the telescopic rod 154 and telescopic rod 156 are fully retracted. Then, the wound drum 170 is removed from the rotating drum 152, a new drum 170 is replaced, and the winding operation is performed again.

[0033] Mounting plate 161 is fixed on the base plate 110, mounting plate 2 162 is fixed on the side of mounting plate 161 near the drum 170, mounting plate 2 162 is located above the expansion member 140, and telescopic rod 3 163 is fixed on the lower side of mounting plate 2 162. Fixing plate 164 is fixed to the lower side of telescopic rod 163; There are two connecting plates 166, which are respectively fixed at both ends of the fixed plate 164 along its length. The lifting plate 167 is fixed between the two connecting plates 166, and the lifting plate 167 is located below the fixed plate 164; The lower side of the lifting plate 167 is always in close contact with the rotating rod 144 inside the uppermost expansion member 140; A gap of five to ten centimeters is left between the lifting plate 167 and the fixing plate 164.

[0034] The lifting plate 167 is an electromagnet structure; The end of guide plate 168 away from the inclined side 169 is made of iron. The iron material at one end of the guide plate 168 is attached to the lifting plate 167 of the electromagnet structure; Specifically, since the end of the guide plate 168 away from the inclined side 169 is located at the opening of the C-shaped rotating rod 144, the flat non-woven fabric edge scalloped lace falling from the guide plate 168 can directly land on the roll 170 or the outermost non-woven fabric of the roll 170. The scalloped lace that lands on the roll 170 or the outermost non-woven fabric of the roll 170 can be directly pressed and fixed in position by the rotating rod 144 inside the subsequent expansion member 140.

[0035] There are multiple guide plates 168; When the nonwoven fabric is wound up, it passes through the gap between the fixing plate 164 and the lifting plate 167.

[0036] Specifically, the position of the guide plate 168 can be adjusted according to the needs so that the inclined edge 169 can contact the scallop-shaped lace of the non-woven fabric. There are multiple guide plates 168, and the appropriate number of guide plates 168 can be selected according to the needs. When a single roll 170 needs to wind up a non-woven fabric with a small width, it may wind up two non-woven fabrics at the same time. In this case, the position and number of guide plates 168 can be adjusted so that the inclined edge 169 can contact the scallop-shaped lace of the non-woven fabric. Furthermore, during the winding operation, the diameter of the nonwoven fabric wound with the roll 170 continuously increases, requiring continuous adjustment of the height of the guide plate 168 and the lifting plate 167 via the telescopic rod 163; while raising the height, it is also necessary to keep the lower side of the lifting plate 167 in close contact with the rotating rod 144 inside the uppermost expansion member 140.

[0037] The electric slide table 141, telescopic rod one 154, telescopic rod two 156 and telescopic rod three 163 are all existing technologies and will not be described in detail here.

[0038] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: Multiple rotating rods 144 are arranged in a C-shape around the outside of the roll 170, and are always pressed against the outermost layer of the fabric roll during the winding process. This provides a continuous radial pressure to the uneven lace, forcing it to wrap neatly around the roll 170, effectively preventing the lace from uncomfortably unraveling and avoiding edge swelling problems. The guide plate 168 set above the multiple rotating rods 144 has a beveled edge 169 that can first contact and catch the non-woven lace in motion. The beveled edge 169 acts as a smooth transition surface, guiding the lace that may fold or sag to a flat state.

[0039] Example 2: During use, the above-mentioned device smooths the scalloped lace edge of the non-woven fabric by using the inclined edge 169 on one side of the guide plate 168. During conveying, it is conveyed smoothly on the guide plate 168. However, the smoothing effect is poor during use. Therefore, the solution of Example 1 is improved, such as... Figures 11-12 As shown: It also includes an expansion assembly 200, which includes an air pump 230 and an airbag 240; The number of airbags 240 is the same as the number of guide plates 168, and they correspond one-to-one. The number of air pumps 230 and airbags 240 are the same, and they correspond one-to-one. Airbag 240 is fixed on the inclined side 169, and air pump 230 is fixed on the lower side of the guide plate 168. Air pump 230 is connected to airbag 240. Specifically, when the scalloped lace edge of the non-woven fabric is smoothed by the inclined edge 169 on one side of the guide plate 168, the airbag 240 is expanded and contracted by the operation of the air pump 230. In this process, the drooping and folded scalloped lace is smoothed.

[0040] When the guide plate 168 is set on the lifting plate 167, the air pump 230 is connected to an external power supply.

[0041] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: Airbag 240 is positioned on the inclined side 169 of guide plate 168 and is periodically expanded and contracted by air pump 230; this reciprocating motion can shake and loosen the lace that is stuck together or folded, realizing dynamic and active sorting of the lace.

[0042] Example 3: When the above device is in use, the guide plate 168 and airbag 240 are used to arrange the scalloped edges of the nonwoven fabric. However, during the winding process, due to the tension, the nonwoven fabric is always under tension. Under the tension, the scalloped edges at the edge of the nonwoven fabric may curl upwards. Furthermore, airflow in the factory can blow the scalloped edges of the nonwoven fabric upwards, causing them to flip to the upper side of the nonwoven fabric. During use, the guide plate 168 and airbag 240 fail to arrange the edges. Therefore, the solution in Example 2 is improved, such as... Figure 1 , Figure 13 As shown: Adjustment component 160 also includes a pressing plate 165; The pressing plate 165 is fixed to the side of the fixing plate 164 away from the mounting plate 161; The side of the pressing plate 165 away from the fixing plate 164 is arc-shaped; The expansion assembly 200 also includes an air pump 210 and an airbag 220; Airbag 220 is fixed to the lower side of the pressing plate 165, and air pump 210 is fixed to the upper side of the pressing plate 165. The output end of air pump 210 is connected to airbag 220.

[0043] When the nonwoven fabric passes through the gap between the fixed plate 164 and the lifting plate 167, the airbag 220 inflates and adheres to the upper side of the nonwoven fabric.

[0044] Specifically, during the conveying of nonwoven fabric, the operation of air pump 210 causes airbag 220 to expand and press against the upper side of the nonwoven fabric. As the nonwoven fabric is continuously rolled up, airbag 220 presses against and flips to the scallop-shaped lace on the upper side of the nonwoven fabric, and the scallop-shaped lace that has flipped to the upper side of the nonwoven fabric presses against and falls back onto guide plate 168.

[0045] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: To prevent lace from curling up or flipping, the pressure plate 165 and the airbag 220 below it are located above the nonwoven fabric before it enters the winding area. When the airbag 220 inflates, it gently presses down on the upper surface of the nonwoven fabric, especially those laces that have curled up or flipped over, pushing them back to their normal position and ensuring effective straightening; whether the lace is sagging, curling up, or flipping over, it can be effectively corrected.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
