Description

Technical Field

[0001] This utility model relates to the field of nonwoven machinery technology, and in particular to a fiber collection device. Background Technology

[0002] Nonwoven fabric, also known as non-woven textile, is a flexible material made by directly forming and bonding fibers into a web. In the nonwoven fabric manufacturing process, the fiber receiving device is a key piece of equipment affecting fiber forming quality and production efficiency. Currently, fiber receiving devices can be mainly divided into two categories: rotary drum type and moving mesh belt type, which enable continuous production and are suitable for large-scale manufacturing. In nonwoven fabric production, increasing the width of the fiber web is crucial for improving production efficiency and meeting the demand for wide-width products. Existing technologies for increasing fiber web width include designing wide spinnerets, fiber web splicing technology, and cross-laying. Wide spinnerets require a longer spinning nozzle range, placing extremely high demands on spinning equipment; fiber web splicing technology uses mechanical or thermal bonding to splice multiple narrow nonwoven fabrics into wide-width products, but uneven strength or appearance defects may exist at the splicing points, ultimately affecting product quality; cross-laying is mostly used in large-scale spinning equipment, making it difficult to miniaturize and resulting in high costs.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0043] The following is combined with Figures 1-2 This invention describes a fiber collecting device. The fiber collecting device includes: a base 1, a linear reciprocating mechanism, a support unit, and a fiber collecting unit.

[0044] The fixed end of the linear reciprocating mechanism is located on the base 1; the support unit is slidably located on the base 1 and connected to the movable end of the linear reciprocating mechanism, and the support unit is driven to make linear reciprocating motion on the base 1 along the first direction through the linear reciprocating mechanism; the fiber collection unit is located on the support unit and is used to collect fibers.

[0045] Specifically, the base 1 serves as the support and mounting part of this device, and it can be in the form of a flat plate supported on a table. The support unit can slide on the base 1, and is driven to move on the base 1 by a linear reciprocating mechanism. The linear reciprocating motion of the support unit drives the fiber collecting unit to move synchronously. The spinneret can only cover a part of the fiber collecting unit, and the width of the spinneret's coverage is limited. Therefore, this invention uses the swing amplitude of the linear reciprocating mechanism to control the periodic reciprocating motion distance of the fiber collecting unit, so that the collecting unit fully covers the fibers, thereby obtaining a controllable fiber web width and expanding the obtained fiber web width. This device has a simple structure, is easy to operate, and can achieve a large width of nonwoven fabric without relying on the width of the spinneret.

[0046] This utility model provides a fiber collecting device, comprising: a base 1, a linear reciprocating mechanism, a support unit, and a fiber collecting unit. The fixed end of the linear reciprocating mechanism is mounted on the base 1; the support unit is slidably mounted on the base 1 and connected to the movable end of the linear reciprocating mechanism, which drives the support unit to perform linear reciprocating motion on the base 1; the fiber collecting unit is mounted on the support unit and is used to collect fibers. This fiber collecting device utilizes the linear reciprocating mechanism to provide linear reciprocating power, and the support unit drives the fiber collecting unit to perform periodic reciprocating motion. The controllable fiber web width is obtained by adjusting the swing amplitude of the linear reciprocating mechanism. This device has a simple structure, is easy to operate, and can achieve large-width nonwoven fabrics without relying on the spinneret width.

[0047] In one embodiment of this utility model, the fiber collecting device further includes at least two linear guide rails 2. Each linear guide rail 2 extends parallel to the movement direction of the linear reciprocating mechanism, and the support unit is slidably mounted on the base 1 via the linear guide rails 2. Preferably, two linear guide rails 2 are provided, which on the one hand can limit the movement direction of the support unit, and on the other hand can support the support unit through the linear guide rails 2. In this embodiment, the linear guide rails 2 are specified to be arranged along the first direction (i.e., the width direction), that is, parallel to the movement direction of the linear reciprocating mechanism, to ensure the accurate movement direction of the fiber collecting unit.

[0048] In one embodiment of this utility model, the support unit includes a support body 31 and a support member 32. The support body 31 is supported on a linear guide rail 2, and a slider is provided on the side near the linear guide rail 2 for sliding engagement with the linear guide rail 2; the support member 32 is fixed on the support body 31 and located at both ends of the fiber collecting unit for supporting the fiber collecting unit. The support body 31 can be made of, for example, Figure 1 The flat plate structure shown can also be adopted as follows: Figure 2 The support frame structure shown has four sliders installed on the lower surface of the support body 31. Each linear guide rail 2 is slidably engaged with two sliders, thereby enabling the support body 31 to slide along the linear guide rail 2. The support member 32 can be a corner bracket, fixed to the upper surface of the support body 31, and located at both ends of the fiber collection unit to support the fiber collection unit.

[0049] In one embodiment of this utility model, the linear reciprocating mechanism includes a first drive unit 41 and a linkage assembly 42. The first drive unit 41 is mounted on a base 1; one end of the linkage assembly 42 is connected to the first drive unit 41, and the other end is connected to a support unit. Specifically, the first drive unit 41 can be a motor, and the linkage assembly 42 consists of two hinged linkages. One end of one linkage is hinged to the output shaft of the motor, and the other linkage is hinged to the support unit. After the motor rotates, the rotational motion is converted into linear reciprocating motion through the linkage assembly 42, thereby driving the support unit to move reciprocally.

[0050] In one embodiment of this utility model, the linear reciprocating mechanism further includes a guide rod 43 and a guide block 44. One end of the guide rod 43 is connected to the connecting rod assembly 42, and the other end is connected to the support unit. The guide block 44 is fixed on the base 1 and has a guide hole, which is fitted onto the guide rod 43 and slidably connected to it. In this embodiment, the guide block 44 and the guide rod 43 define the direction of movement of the support unit. Specifically, the guide rod 43 is a straight rod extending along a first direction (i.e., the width direction), and the guide block 44 is fixed on the base 1, defining the direction of movement of the guide rod 43 through its guide hole. When the motor rotates, it drives the connecting rod to move, which is converted into the linear reciprocating motion of the guide rod 43, thereby driving the support unit to move synchronously. It is understood that the inner diameter of the guide hole matches the outer diameter of the guide rod 43 to ensure its defining and sliding functions.

[0051] In one embodiment of this utility model, the fiber collecting device further includes: a mounting base 45, which is fixed on the base 1 and has a first mounting position and a second mounting position; a first driving unit 41 is fixed on the first mounting position; and a guide block 44 is fixed on the second mounting position. Specifically, the first mounting position is located at one end of one side of the mounting base 45, and the second mounting position is located at the other end of the other side of the mounting base 45.

[0052] In one embodiment of this utility model, such as Figure 1 As shown, the fiber collection unit includes: a second drive unit 51, multiple first rollers 52, and a base fabric 53. The second drive unit 51 is mounted on a support unit; the multiple first rollers 52 are rotatably mounted on the support unit along a second direction and connected to the second drive unit 51; the base fabric 53 is tensioned on the first rollers 52. Preferably, the second drive unit 51 can be a motor, using two first rollers 52. One first roller 52 is driven to rotate, thereby moving the base fabric 53. The other first roller 52 rotates synchronously. With the movement of the base fabric 53, fibers of a larger length can be collected. After the fibers are collected on the base fabric 53, the first roller 52 rotates, and the fibers move to one end of the first roller 52 and fall off the base fabric 53 due to their own weight. A collection bucket or transport device can be arranged downstream to collect the fibers. In addition, the length of the first roller 52 is less than the length of the first linear guide 2, and is determined according to the required width of the nonwoven fabric, and is greater than or equal to the required width of the nonwoven fabric; the rotational speed of the first roller 52 is controlled by the second drive unit 51 connected to it, and its rotational speed adjustment range is preferably 1-10 rpm.

[0053] Preferably, in the above embodiment, the movement direction of the base fabric 53 driven by the first roller 52 (i.e., the second direction) is perpendicular to the movement direction of the linear reciprocating mechanism (i.e., the first direction), thereby increasing the width and length of the obtained fibers. Additionally, the rotational speed of the second drive unit 51 can be adjusted to regulate the thickness of the obtained fibers; increasing the rotational speed of the second drive unit 51 reduces the fiber thickness, while decreasing the rotational speed increases the fiber thickness.

[0054] In one embodiment of this utility model, the base fabric 53 has a porous structure. Unlike the above embodiments, the porous structure formed on the base fabric 53 allows for the placement of a negative pressure fan below the base fabric 53, enabling it to have a suction function, increasing the fiber stretching speed, and increasing the adhesion between the fiber web and the base fabric 53.

[0055] In one embodiment of this utility model, such as Figure 2 As shown, the fiber collection unit includes a third drive unit 54 and a second roller 55. The third drive unit 54 is mounted on a support unit; the second roller 55 is rotatably mounted on the support unit along a second direction and connected to the third drive unit 54. In this embodiment, fibers are collected directly through the second roller 55. During the collection process, the third drive unit 54 drives the second roller 55 to rotate. The surface of the second roller 55 can be a continuous smooth cylindrical surface. A smooth cylindrical surface is mainly suitable for processes such as electrospinning that do not require airflow stretching.

[0056] In one embodiment of this utility model, the cylindrical surface of the second roller 55 has a porous structure and / or a slotted structure. The aforementioned open cylindrical surface can reduce airflow reflection and significantly improve the adsorption of the fiber web, making it suitable for technologies involving stretching airflow, such as spunbond and meltblown processes. Alternatively, a negative pressure fan can be configured inside the second roller 55 to enable it to have a suction function, thereby increasing the fiber stretching speed and the adhesion between the fiber web and the base fabric 53.

[0057] To achieve miniaturization, the fiber collection device offers the following three design parameters:

[0058] Example 1:

[0059] like Figure 1 The double roller structure shown has a diameter of 20 cm and a length of 40 cm. The roller rotation speed is set to 2 rpm. The swing amplitude of the connecting rod assembly 42 of the linear reciprocating mechanism is 20 cm, the moving speed is 2 rpm, the obtainable fiber width is 38 cm, and the minimum effective length of the fiber web is 60 cm.

[0060] Example 2:

[0061] like Figure 2The single-roller structure shown has a roller diameter of 10 cm and a length of 40 cm. The roller speed is set to 5 rpm. The connecting rod assembly 42 of the linear reciprocating mechanism has an oscillation amplitude of 20 cm and a moving speed of 2 rpm. The obtainable fiber width is 38 cm and the maximum fiber web length is 31 cm. This device can only achieve fiber width control.

[0062] Comparative example:

[0063] In such Figure 2 The linear reciprocating mechanism is removed from the single-roller structure shown. The diameter and length of the roller are 10 cm and 40 cm, respectively. The rotation speed of the roller is set to 5 rpm. The width of the fiber web depends on the spinneret range. The spinneret used has a spinneret range of 20 cm. Therefore, the fiber width on the collection roller is 20 cm and the fiber web length is 31 cm. The fiber width obtained by this device is determined by the spinning nozzle, and the length depends on the roller diameter.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
