Description

Technical Field

[0001] This invention relates to the field of fabric preparation technology, specifically to an apparatus for preparing flame-retardant and breathable fabrics. Background Technology

[0002] Currently, certain fields require fabrics with flame-retardant and breathable properties. Therefore, flame-retardant and breathable fabrics are widely used in these fields. Traditionally, flame-retardant and breathable fabrics are sewn together. Currently, when sewing flame-retardant and breathable fabrics, sewing devices are used to sew the edges together. However, this requires manual assistance to tighten the flame-retardant and breathable fabrics to ensure edge alignment and prevent misalignment, skewing, or unevenness during fabric movement. This ensures the strength of the seam and the stability of the overall structure. However, manual assistance is cumbersome, increases labor intensity, and reduces work efficiency. Therefore, we propose a device for preparing flame-retardant and breathable fabrics. Summary of the Invention

One side of the sewing device is provided with a winding device for winding the flame-retardant and breathable fabric. A sewing auxiliary assembly is provided on the base between the unwinding device and the sewing device. The sewing auxiliary assembly includes:

[0006] A two-way slide rail module is mounted on the base and is parallel to the width direction of the base;

[0007] The mounting plate has two sets, mounted on the bidirectional slide rail module, and is driven by the bidirectional slide rail module to move in opposite directions; and...

[0008] The clamping part, located on the mounting plate, is used to clamp the edges of flame-retardant and breathable fabrics.

[0009] A further improvement is that the clamping part includes:

[0010] The lower support roller plate is provided in several groups, which are arranged parallel to each other on the mounting plate, and the several groups of lower support roller plates are respectively attached to the bottom of the flame retardant fabric and the breathable fabric.

[0011] The upper support roller plate has several sets, which are movably mounted on the mounting plate. Each set of upper support roller plates is respectively attached to the top of the flame-retardant fabric and the breathable fabric. The ends of the upper support roller plates are slidably connected to vertical sliding openings on the mounting plate via sliders. A lead screw is rotatably mounted within the vertical sliding opening, and the lead screw thread passes through the slider.

[0012] The drive unit, mounted on the mounting plate, is used to drive the lead screw to rotate.

[0013] A further improvement is that the sewing auxiliary assembly further includes an adhesive application assembly disposed on the mounting plate facing the sewing device, the adhesive application assembly comprising:

[0014] Adhesive supply device, mounted on mounting plate; and,

[0015] The glue-applying roller is connected to the mounting plate via a bracket and communicates with the output end of the glue supply device. The glue-applying roller is located at the edge between the flame-retardant fabric and the breathable fabric, and is located outside the sewing end of the sewing device.

[0016] A further improvement is that the sewing auxiliary assembly further includes a pressing assembly disposed on the base and located between the adhesive application assembly and the sewing device, the pressing assembly comprising:

[0017] A frame is mounted on a base and is fitted over the flame-retardant fabric and the breathable fabric. The upper and lower ends of the frame are equipped with telescopic devices. The output end of the telescopic device extends into the frame and is connected to a hot press roller for pressing the flame-retardant fabric and the breathable fabric together.

[0018] A further improvement is that the sewing aid assembly also includes a cleaning component located on the side of the mounting plate away from the adhesive application assembly and at the edge between the flame-retardant fabric and the breathable fabric, the cleaning component comprising:

[0019] A mounting frame, connected to a mounting plate, is T-shaped. Rollers are symmetrically arranged on the vertical section of the mounting frame. Each roller has a cavity, and a take-up roller and an unwind roller are rotatably mounted at opposite ends within the cavity. The take-up roller is driven to rotate by a miniature rotating device located within the cavity. A dust-adhesive film is wound around the outer wall of the take-up roller, with one end of the film penetrating through the roller body, wrapping around the outer wall of the roller body, and then penetrating the roller body again to wrap around the outer wall of the unwind roller.

[0020] The battery is located in a cavity inside the roller body, and a micro controller is also installed in the cavity.

[0021] A further improvement is that the roller body is detachably and fixedly sleeved on the outer wall of the rotating shaft, the rotating shaft is rotatably mounted on the sliding seat, and the sliding seat is slidably mounted in a vertical opening on the outer wall of the vertical section of the mounting frame. The inner wall of one end of the vertical opening and the sliding seat are connected by an elastic element, which is used to drive the sliding seat to move vertically away from the center of the mounting frame. The inner wall of the other end of the vertical opening is provided with a distance sensor for detecting the position of the sliding seat. When the sliding seat moves to a preset position, the distance sensor controls the micro-rotating device to work through a microcontroller.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1) The present invention is equipped with a sewing auxiliary component. After the edges of the breathable fabric and the flame-retardant fabric are aligned in advance, they are pressed together by the pressing part, and the two mounting plates are driven to move away from each other simultaneously to tighten the breathable fabric and the flame-retardant fabric. This allows the breathable fabric and the flame-retardant fabric to maintain tension and stable alignment during the sewing process, reducing problems such as misalignment, skewing, and unevenness of the fabric during the process. At the same time, it reduces wrinkles, ensures the firmness of the stitches and the stability of the overall structure, and thus improves the durability of the prepared flame-retardant and breathable fabric.

[0028] 2) The sewing auxiliary component of the present invention is further provided with an adhesive application component and a pressing component, so that the edges of the breathable fabric and the flame-retardant fabric are bonded together for pre-positioning before sewing, which further reduces the problems of misalignment, skewing and unevenness of the fabric during the process of movement, and ensures that the edges of the breathable fabric and the flame-retardant fabric are stably aligned for sewing.

[0029] 3) The sewing auxiliary component of the present invention is also provided with a cleaning component, which cleans the edge bonding area of ​​the breathable fabric and the flame-retardant fabric before the glue application component and the pressing component, so as to ensure the quality of the subsequent bonding of the two.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see the appendix Figure 1

[0039] An apparatus for preparing flame-retardant and breathable fabric includes a base 1, and an unwinding device for unwinding flame-retardant fabric 3 and breathable fabric 5 is provided on one side of the top of the base 1.

[0040] A sewing device 7 is provided on the other side of the top of the base 1. The sewing device 7 is used to sew the edges of the flame-retardant fabric 3 and the breathable fabric 5 to form a flame-retardant and breathable fabric. The sewing device 7 is a conventional structure in the art and will not be described in detail here. For example, it is a sewing machine.

[0041] One side of the sewing device 7 is provided with a winding device 8 for winding flame-retardant and breathable fabric. The winding device 8 is a conventional structure in the art, including, for example, a winding roller and a winding motor that drives the winding roller to rotate.

[0042] A sewing auxiliary component 6 is provided on the base 1 between the unwinding device and the sewing device 7. The sewing auxiliary component 6 includes:

[0043] The bidirectional slide rail module 62 is disposed on the base 1 and parallel to the width direction of the base 1. The bidirectional slide rail module 62 includes, for example, a guide rail, a bidirectional lead screw rotatably disposed in the guide rail, a slider threaded on both ends of the outer wall of the bidirectional lead screw and slidably connected to the guide rail, and a motor that drives the bidirectional lead screw to rotate. Of course, it is not limited to this structure.

[0044] Mounting plates 61, comprising two sets, are mounted on a bidirectional slide rail module 62. The bidirectional slide rail module 62 drives the two sets of mounting plates 61 to move in opposite directions, i.e., the two sets of mounting plates 61 move closer to or further apart from each other; and...

[0045] A pressing part, located on the mounting plate 61, is used to press the edges of the flame-retardant fabric 3 and the breathable fabric 5.

[0046] When preparing the flame-retardant and breathable fabric, after the edges of the flame-retardant fabric 3 and the breathable fabric 5 are aligned, the two ends of the flame-retardant fabric 3 and the breathable fabric 5 are pressed by two pressing parts respectively. At the same time, the two mounting plates 61 are driven away from each other by the bidirectional slide rail module 62, which tightens the flame-retardant fabric 3 and the breathable fabric 5. In this way, wrinkles will not occur when sewing the edge area of ​​the fabric later, and the neatness of the sewn fabric edge is also guaranteed, reducing the burden of later fabric processing.

[0047] Please see the appendix Figure 2

[0048] Preferably, the clamping part in this embodiment includes:

[0049] The lower support roller plate 63 is provided in several groups and is arranged parallel to the mounting plate 61. The several groups of lower support roller plates 63 are respectively attached to the bottom of the flame-retardant fabric 3 and the breathable fabric 5. The lower support roller plate 63 includes a plate body and several groups of rollers embedded in the top of the plate body so that the flame-retardant fabric 3 and the breathable fabric 5 can move relative to the lower support roller plate 63.

[0050] The upper support roller plate 64, comprising several sets, is movably mounted on the mounting plate 61. These sets of upper support roller plates 64 are respectively attached to the top of the flame-retardant fabric 3 and the breathable fabric 5. The upper support roller plate 64 has the same structure as the lower support roller plate 63, and together they press the edges of the flame-retardant fabric 3 or the breathable fabric 5 together. The end of the upper support roller plate 64 is slidably connected to a vertical sliding opening on the mounting plate 61 via a slider. A lead screw 65 is rotatably mounted within the vertical sliding opening, threaded through the slider. Rotating the lead screw 65 adjusts the position of the upper support roller plate 64, ensuring it engages with the corresponding lower support roller plate 63 to press the edges of the flame-retardant fabric 3 or the breathable fabric 5.

[0051] A drive component 66 is mounted on a mounting plate 61 and is used to drive the lead screw 65 to rotate.

[0052] The drive component 66 can be, for example, a servo motor and a reducer, or it can be a drive handwheel and a sprocket drive assembly that connects the drive handwheel to the lead screw 65.

[0053] Preferably, the sewing auxiliary component 6 in this embodiment further includes an adhesive application component 68 disposed on the mounting plate 61 facing the sewing device 7. The adhesive application component 68 includes:

[0054] A glue supply device 681 is mounted on a mounting plate 61. The glue supply device 681 is a conventional device in the art, including, for example, a glue supply hopper and a pump body connected to the output end of the glue supply hopper; however, the glue supply device 681 is not limited to this type.

[0055] The glue-applying roller 682 is connected to the mounting plate 61 via a bracket and communicates with the output end of the glue supply device 681. The glue-applying roller 682 is located at the edge between the flame-retardant fabric 3 and the breathable fabric 5, and is situated outside the sewing end of the sewing device 7. Figure 5 As can be seen, the coating area a formed at the edge between the flame-retardant fabric 3 and the breathable fabric 5 is located outside the sewing area b of the sewing device 7, which makes the edge of the prepared flame-retardant and breathable fabric less prone to cracking and damage during later use. The coating roller 682 is a conventional structure in this field and will not be described in detail here.

[0056] Before sewing flame-retardant fabric 3 and breathable fabric 5, adhesive is applied to their edges by adhesive application component 68, so that the edges of flame-retardant fabric 3 and breathable fabric 5 are pre-bonded and positioned to ensure that the edges of flame-retardant fabric 3 and breathable fabric 5 are stably aligned for sewing.

[0057] Preferably, the sewing auxiliary component 6 in this embodiment further includes a pressing component 69 disposed on the base 1 and located between the adhesive application component 68 and the sewing device 7. The pressing component 69 includes:

[0058] A frame 691 is mounted on a base 1 and is fitted over the outer side of the flame-retardant fabric 3 and the breathable fabric 5. Both the upper and lower ends of the frame 691 are provided with telescopic devices 692, such as cylinders. The output end of the telescopic device 692 extends into the frame 691 and is connected to a hot press roller 693 for pressing the flame-retardant fabric 3 and the breathable fabric 5 together. The hot press roller 693 is a conventional structure in the art and will not be described in detail here.

[0059] After the flame-retardant fabric 3 and the breathable fabric 5 are coated with adhesive and before sewing, they pass through the pressing component 69. The telescopic device 692 drives the hot pressure roller 693 to press the upper and lower flame-retardant fabric 3 toward the breathable fabric 5. At the same time, the hot pressure roller 693 generates heat, so that the edges of the flame-retardant fabric 3 and the breathable fabric 5 are pre-bonded and positioned together.

[0060] Please see the appendix Figure 3 -Appendix Figure 4

[0061] Preferably, the sewing auxiliary component 6 in this embodiment further includes a cleaning component 67 disposed on the side of the mounting plate 61 away from the adhesive application component 68 and located at the edge between the flame-retardant fabric 3 and the breathable fabric 5. The cleaning component 67 includes:

[0062] Mounting bracket 671 is connected to mounting plate 61. Mounting bracket 671 is T-shaped, and rollers 674 are symmetrically arranged on the vertical section of mounting bracket 671, that is, there are two sets of rollers 674. Figure 3 As can be seen, one roller 674 is in contact with the flame-retardant fabric 3, and the other roller 674 is in contact with the breathable fabric 5. A cavity 676 is provided inside the roller 674. A take-up roller 677 and an unwind roller 6710 are rotatably mounted at both ends of the cavity 676. The take-up roller 677 is driven to rotate by a miniature rotating device 679 located within the cavity 676. The miniature rotating device 679 is, for example, a miniature motor. An adhesive film 6714 is wound around the outer wall of the take-up roller 677. The adhesive film 6714 is used to remove dust from the opposite edges of the flame-retardant fabric 3 and the breathable fabric 5 to ensure the subsequent bonding strength of the edges of the flame-retardant fabric 3 and the breathable fabric 5, and also to improve the subsequent sewing quality of the fabric. One end of the adhesive film 6714 movably penetrates the roller 674 and wraps around the outer wall of the roller 674 before penetrating the roller 674 and wrapping around the outer wall of the unwind roller 6710. Figure 3 It can be seen that the upper part of the roller body 674 has two sets of openings for the two ends of the adhesive film 6714 to pass through and exit respectively; and,

[0063] The storage battery 6713 is located in a cavity inside the roller body 674, and a micro controller is also installed in the cavity.

[0064] During use, the roller 674 rotates under the drive of the flame-retardant fabric 3 and the breathable fabric 5. When rotating, the dust removal film 6714 removes dust from the edges of the flame-retardant fabric 3 and the breathable fabric 5. After long-term use, the take-up roller 677 is rotated by controlling the micro-rotating device 679, so that the unwinding roller 6710 unwinds the dust removal film 6714. This allows the dust removal film 6714 without dust or other adhering parts to be wrapped around the outer wall of the roller 674, ensuring the cleaning effect of the cleaning component 67 for long-term use.

[0065] It should be noted that one end of the roller body 674 may have an opening that communicates with the cavity 676, and the cover of the opening can be removed in order to maintain the internal structure of the cavity 676.

[0066] Preferably, in this embodiment, the roller 674 is detachably and fixedly sleeved on the outer wall of the rotating shaft 6712, for example, by means of a snap-fit ​​connection. The rotating shaft 6712 is rotatably mounted on the sliding seat 672 via a bearing. The sliding seat 672 is slidably mounted in a vertical opening on the outer wall of the vertical section of the mounting frame 671. The inner wall of one end of the vertical opening and the sliding seat 672 are connected by an elastic member 673. The elastic member 673 is used to drive the sliding seat 672 to move vertically away from the center of the mounting frame 671, so that the roller 674 is in close contact with the flame-retardant fabric 3 or the breathable fabric 5. The inner wall of the other end of the vertical opening is provided with a distance sensor 675 for detecting the position of the sliding seat 672. The distance sensor 675 is a conventional structure in the art and will not be described in detail here. When the sliding seat 672 moves to a preset position, the distance sensor 675 controls the micro-rotating device 679 to work through a microcontroller.

[0067] As more and more dust adheres to the adhesive film 6714, its thickness changes. This causes the elastic element 673 to move, thus changing the distance between the distance sensor 675 and the sliding seat 672. When the distance between them reaches a preset threshold, the distance sensor 675 sends a control signal to the microcontroller, causing the micro-rotating device 679 to operate. The portion of the adhesive film 6714 without dust or other adhering material then wraps around the outer wall of the roller 674. At this point, the thickness of the adhesive film 6714 returns to its initial state, and the sliding seat 672 resets under the action of the elastic element 673. The micro-rotating device 679 then stops operating.

[0068] Preferably, in this embodiment, the take-up roller 677 and the unwind roller 6710 are connected by a linkage component. The linkage component includes a drive gear 678 sleeved on the outer wall of the roller shaft of the take-up roller 677. A driven gear set meshes with one side of the drive gear 678. The driven gear set includes a shaft and a driven gear rotatably mounted on the shaft and meshing with the drive gear 678 to change the direction of rotation. The driven gear set is rotatably disposed within the cavity 676. The shaft of the driven gear set and the unwind roller 6710 are connected. The shaft of 10 is connected by a sprocket drive assembly 6711, which includes two sets of sprockets and a chain. This ensures that when the take-up roller 677 takes up the adhesive film 6714, the unwind roller 6710 unwinds the adhesive film 6714 simultaneously. When the micro-rotating device 679 stops working, the take-up roller 677 and the unwind roller 6710 cannot rotate, which makes it difficult for the adhesive film 6714 on the outer wall of the roller body 674 to move relative to the roller body 674 when it rotates.

[0069] Preferably, the unwinding device of this embodiment includes:

[0070] Unwinding device 2, consisting of two sets, is symmetrically positioned on base 1 via supports, and is used for unwinding flame-retardant fabric 3; and,

[0071] Unwinding device 2 4 is mounted on base 1 and located on one side of unwinding device 1 2. It is used to unwind breathable fabric 5, which is located between two sets of flame-retardant fabric 3. Unwinding device 1 2 and unwinding device 2 4 are both conventional structures in this field and will not be described in detail here. The flame-retardant breathable fabric prepared by this device consists of two sets of breathable fabric 5 and a breathable fabric 5 sewn between the two sets of breathable fabric 5.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
