Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to a hem guiding device. Background Technology

[0002] The raw fabric of clothing usually has raw edges after being cut. In order to make the finished garment neater and more beautiful, the raw edge of the fabric needs to be rolled up before sewing.

[0003] Currently, most fabric hemming operations are completed automatically by hemming machines. However, traditional hemming machines are usually only suitable for a single hemming width. If different hemming widths are required, a hemming machine of the corresponding size and specifications needs to be replaced. Furthermore, when hemming fabrics with high stiffness and thickness (such as denim and workwear fabrics), the hemming machine has difficulty hemming the fabric smoothly and reliably due to the stiffness of these fabrics. This results in unstable hemming quality and fails to meet the needs of automated continuous production. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a curling edge guiding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hemming guide device includes a mounting base and a folded fabric block and a hemming plate distributed on the mounting base. The folded fabric block is provided with an inclined guide plate, a downwardly distributed air blowing hole one, and a horizontally distributed air blowing hole two in sequence. The guide plate is provided with a guide slope for inclined downward guidance. The air blowing hole two is arranged towards the hemming groove of the hemming plate.

[0007] Preferably, a support plate is fixed on the mounting base, and a fabric groove is formed between the support plate and the folded fabric block. The upper end of the guide plate is set higher than the support plate.

[0008] Preferably, the number of the second type of air holes is multiple and they are spaced apart on the folded cloth block.

[0009] Preferably, speed control valves are installed on the first and second air inlets.

[0010] Preferably, the guide ramp is arranged in a stepped manner at the lower end of the guide plate, and the guide ramps distributed in an adjacent stepped manner are arranged with the inner side higher than the outer side.

[0011] Preferably, the mounting base is provided with a side plate for mounting the folded fabric block, and a through groove for conveying the fabric edge rolling is formed between the side plate and the edge rolling plate. The edge rolling plate is slidably mounted on the mounting base and can be driven to move relative to the side plate.

[0012] Preferably, a partition plate is installed on the rolled edge plate within the through groove, the partition plate being disposed between the upper and lower ends of the arc-shaped rolled edge groove and spaced apart from the rolled edge groove.

[0013] Preferably, a drive plate is connected to the rolled edge plate, and the drive plate is driven by a drive component to move the rolled edge plate laterally.

[0014] Preferably, the driving component includes a motor, and a lead screw for driving the displacement of the drive plate is connected to the drive end of the motor.

[0015] Preferably, the rolled edge plate is fixed with a slider that can slide laterally along the mounting base.

[0016] The beneficial effects of this invention are:

[0017] A guide plate, air hole one, and air hole two are sequentially arranged on the folding block. The guide plate's inclined surface guides the rolled edge of the fabric to be folded downwards at an angle. Air is blown downwards through air hole one to straighten the folded rolled edge. Then, air is blown horizontally through air hole two to fold the rolled edge horizontally and blow it towards the rolling plate. The rolled edge is then guided by the rolling groove of the rolling plate to achieve the hemming operation of the fabric. Thus, this invention uses the guide plate, air hole one, and air hole two on the folding block to perform multiple folding transitions on the fabric to be rolled, which can adapt to the stable and reliable hemming of thick and hard fabrics, and ensure the smoothness of the fabric hemming operation, greatly improving production quality and efficiency.

Detailed Implementation

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1-10 As shown, this embodiment discloses a hemming guide device, including a mounting base 1 and folding fabric blocks 32 and hemming plates 4 distributed front and rear on the mounting base 1. A support plate 2 is fixed on the mounting base 1, and the support plate 2 is used to support and convey the fabric 6 to be hemmed. (Refer to...) Figure 1 As shown, the fabric 6 can be conveyed from front to back along the support plate 2.

[0033] The folded fabric block 32 is provided with an inclined extending guide plate 33, a downwardly distributed air blowing hole 34, and a horizontally distributed air blowing hole 35. The guide plate 33, the air blowing hole 34, and the air blowing hole 35 are arranged in sequence from front to back. A fabric groove 31 is formed between the support plate 2 and the folded fabric block 32. The rolled edge 61 on the side of the fabric 6 can pass through the fabric groove 31 and be folded downward.

[0034] The upper end of the guide plate 33 is set higher than the support plate 2 so that the rolled edge 61 on one side of the fabric 6 can stably abut against the lower end surface of the guide plate 33, and the rolled edge 61 is tilted downward by the guide plate 33. At the same time, it avoids the side of the thicker and harder fabric 6 from curling up (i.e. the rolled edge 61 curls up higher than the upper end of the guide plate 33, causing the fabric 6 to be unable to tilt downward and fold), which would affect the subsequent rolling edge operation of the fabric 6, making the rolling edge operation of this embodiment more stable and reliable.

[0035] Specifically, the guide plate 33 is provided with a guide slope 331 for inclined downward guidance. The guide slope 331 is set with the front end higher than the rear end, and the rear end height of the guide slope 331 is lower than that of the support plate 2. During the process of conveying the fabric 6 from front to back, the rolled edge 61 is tilted and folded downward by the guide slope 331 (see reference). Figure 6 (The state shown in fabric 6).

[0036] Furthermore, the guide slope 331 is arranged in a stepped manner at the lower end of the guide plate 33. That is, there are multiple guide slopes 331 arranged adjacent to each other at the lower end of the guide plate 33. The adjacent stepped guide slopes 331 are arranged with the inner side higher than the outer side. Thus, the rolled edge portion 61 that is tilted downward can be tilted against the multiple stepped guide slopes 331. That is, the multiple guide slopes 331 also form a tilted downward folding guide in the lateral direction, so that the rolled edge portion 61 can be folded downward more smoothly. Thus, through the combined action of multiple stepped guide slopes 331 and the tilted downward folding of the rolled edge portion 61, the rolled edge portion 61 of the thicker and harder fabric 6 can be tilted downward and folded downward, and a transition is provided for the subsequent vertical folding of the rolled edge portion 61.

[0037] After the rolled edge 61 is tilted downward by the guide slope 331, air is blown downward through the air blowing hole 34 and acts on the tilted downward rolled edge 61 to blow the rolled edge 61 into a vertical state (see reference). Figure 7 (The state shown in fabric 6).

[0038] The second air hole 35 is positioned toward the hemming groove 41 of the hemming plate 4, so that the second air hole 35 can blow air horizontally to blow the vertical hemmed part 61 horizontally toward the hemming groove 41, so that the hemmed part 61 can move with the fabric 6 and hem the fabric 6 through the hemming groove 41.

[0039] Furthermore, there are multiple air holes 35 distributed at intervals on the folded cloth block 32. In this embodiment, two air holes 35 are provided at the front and back of the folded cloth block 32 (or more than two air holes 35 can be provided according to actual needs).

[0040] In this embodiment, air is blown laterally onto the vertically positioned rolled edge portion 61 through the first air blowing hole 35, so that the rolled edge portion 61 can gradually tilt and transition towards the side of the rolled edge plate 4 (see reference). Figure 8 (as shown in the state of the middle fabric 6), and then horizontal air blowing is performed on the inclined transition rolled edge 61 through the second air blowing hole 35 to shape it (refer to) Figure 9 (as shown in the state of fabric 6), so that even the thicker and stiffer fabric 6 can be folded stably, in order to ensure the reliability of the subsequent hemming of fabric 6.

[0041] Furthermore, speed control valves are installed on the first air hole 34 and the second air hole 35 to control the airflow speed at the first air hole 34 and the second air hole 35, thereby meeting the processing needs of fabrics 6 with different thicknesses and hardnesses.

[0042] The mounting base 1 is provided with a side plate 3 for mounting the folded fabric block 32. A through groove 42 for conveying the fabric edge rolling is formed between the side plate 3 and the edge rolling plate 4. The edge rolling part 61 can be conveyed back and forth along the through groove 42 and the edge rolling groove 41 rolls the edge of the fabric 6 (see reference). Figure 10 (The state shown in fabric 6).

[0043] Furthermore, a partition plate 43 located in the through groove 42 is installed on the rolled edge plate 4. The partition plate 43 is located between the upper and lower ends of the arc-shaped rolled edge groove 41 and is spaced apart from the rolled edge groove 41, so as to guide and position the rolled edge of the rolled edge part 61 through the partition plate 43. That is, the rolled edge part 61 is attached to the upper and lower ends of the partition plate 43, and the left and right sides of the rolled edge part 61 are attached to the left and right sides of the partition plate 43.

[0044] In this embodiment, the guide slope 331 on the guide plate 33 guides the hem portion 61 of the fabric 6 to tilt downwards and folds it. Air is blown downwards through the first air blown hole 34 to make the tilted and folded hem portion 61 of the fabric 6 vertical. Then, air is blown horizontally through the second air blown hole 35 to fold the hem portion 61 horizontally and blow it towards the hem plate 4. The hem portion 61 is then guided by the hem groove 41 of the hem plate 4 to achieve the hem operation of the fabric 6. In this embodiment, the guide plate 33, the first air blown hole 34, and the second air blown hole 35 on the folding block 32 can work together to fold the fabric 6 to be hem multiple times, so as to adapt to the stable and reliable hem of the thick and hard fabric 6, and ensure the smoothness of the hem operation of the fabric 6, which greatly improves the production quality and efficiency.

[0045] Furthermore, the hem plate 4 is slidably mounted on the mounting base 1 and can be driven to move relative to the side plate 3. Specifically, a drive plate 5 is connected to the hem plate 4. The drive plate 5 is fixedly mounted on the lower end of the hem plate 4. The drive plate 5 is driven by the drive component 52 to move the hem plate 4 laterally, so as to adjust the width of the through groove 42 and thus adapt to the hem of fabrics 6 of different widths.

[0046] The driving component 52 includes a motor, and a lead screw 51 for driving the displacement of the driving plate 5 is connected to the driving end of the motor so as to drive the driving plate 5 to move laterally through the lead screw 51. A slider 44 that can slide laterally along the mounting base 1 is fixed on the rolled edge plate 4. The slider 44 is slidably connected to the slide rail of the mounting base 1. The slide rail of the mounting base 1 is laterally distributed and fixed on the mounting base 1.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
