Description

Technical Field

[0001] This invention relates to the field of sewing technology, specifically to a method for blowing and shaping the hem of cylindrical fabrics. Background Art

[0002] Currently, the hem of cylindrical fabrics is typically sewn using a cylindrical hem rolling machine. The process of folding the raw edges of the cylindrical fabric inwards before sewing is called hemming. This makes the garment's edge outline smoother and more aesthetically pleasing, and also prevents the fabric from fraying; it's a common garment processing method. Cylindrical fabrics typically have seams on one or both sides. During the hemming process, the seams need to be bent before sewing them.

[0003] Current hemming devices generally use a direct airflow hemming method, where an air inlet is fixed at a predetermined position on the hem rolling machine to directly blow air into the seam. This type of hemming device is currently used in the hemming process of cylindrical fabrics. Because the hemming seam is folded along with the cylindrical fabric, hemming the seam is difficult, especially with thick fabrics. Furthermore, when blowing air into the hemming seam, most of the airflow flows outwards along the seam, which can easily lead to unsuccessful hemming in some areas, particularly in folded areas, thus affecting the sewing quality.

[0004] For example, Chinese Patent Publication No. CN216040137U, entitled "An Automatic Air Blowing and Bending Device for Sewing Machines," includes a fixedly installed bending plate with air blowing pipes fixedly installed at both ends of the bending plate. The air blowing pipes are used to blow air directly into the seam to soften the bone. However, when applied to the process of hemming and sewing to blow air directly into the seam to soften the bone, it also suffers from the aforementioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a method for air-blowing bone repositioning of rolled edges that can effectively improve the success rate of bone repositioning in rolled edges, thereby effectively solving the problem of affecting sewing quality due to unsuccessful bone repositioning in some bone positions.

[0006] The technical solution of this invention is: A method for defrosting sutures by blowing air, employing an air defrosting device, comprising: The inverted bone plate is equipped with an air blowing channel and an air blowing hole connected to the air blowing channel; The reverse bone plate translation mechanism drives the reverse bone plate to translate. The method of inflating and repositioning the rolled-edge bone joints includes the following steps. First, the reverse plate translation mechanism drives the reverse plate to insert between the upper and lower layers of fabric of the rolled edge, so that the air blowing hole is close to the folded part of the rolled edge. Second, pressurized gas is introduced into the air blowing channel, and air is blown into the bone seam of the rolled edge through the air blowing hole for a set time t1 to reverse the bone seam of the rolled edge fold. Third, the reverse plate translation mechanism drives the reverse plate to translate outward from the rolled edge, moving the reverse plate outside the rolled edge. During this process, air is blown into the seams of the rolled edge through the air inlet to reverse the seams of the remaining parts of the rolled edge. In the first step of the rolled edge seam air reversal method of this scheme, the reverse plate is inserted between the upper and lower layers of fabric of the rolled edge by the reverse plate translation mechanism, so that the air inlet is close to the folded part of the rolled edge; then in the second step, air is blown into the seams of the rolled edge through the air inlet for a set time t1 to reverse the seams of the folded part of the rolled edge. During this process, the air inlet is close to the folded part of the rolled edge fabric, which can effectively improve the success rate of reversing the seams of the folded part of the rolled edge, so that the seams of the folded part of the rolled edge fabric are successfully reversed. Next, in the third step, the rebar plate translation mechanism drives the rebar plate to move outward from the rolled edge, so that the rebar plate is moved outside the rolled edge. During this process, air is blown into the bone seams of the rolled edge through the air blowing holes, and the bone seams of the remaining parts of the rolled edge are rebarned in sequence, thereby effectively improving the success rate of rebarning the bone seams of the remaining parts of the rolled edge. Therefore, the rolled edge bone seam air blowing rebar method of this solution can effectively improve the success rate of rebarning the bone seams of the rolled edge, thereby effectively solving the problem of affecting the sewing quality due to unsuccessful rebarning of some bone positions.

[0007] Preferably, the air-blowing bone-setting device also includes: The fixed support plate blocks the folded part of the rolled edge. The bony plate is located on one side of the support plate, and the air hole is located on the side of the bony plate, with the air hole close to one end of the bony plate. The deflector plate is located on one side of the inverted bone plate where the air blowing hole is located. The air blowing hole is located between the deflector plate and the backing plate, and the deflector plate is close to the air blowing hole.

[0008] In the first step, there is a set distance between the guide plate and the bone seam of the rolled edge; In the second step, during the blowing of air through the air holes towards the seam, the airflow is guided by the support plate and the deflector. When the airflow encounters the seam, the airflow along the seam direction is reduced, while the airflow across the seam is increased. This causes the seam to flip, thus achieving the deboning of the seam at the folded part of the rolled edge. Based on this, due to the obstruction and guidance of the support plate and the deflector, most of the airflow during the second step will flow across the seam, rather than flowing outwards along the seam. This airflow can drive the seam to flip, achieving deboning and further effectively improving the success rate of deboning the seam at the folded part of the rolled edge, ensuring the successful deboning of the seam at the folded part of the rolled edge fabric. Simultaneously, during this process, the air holes are close to the folded part of the rolled edge fabric, the distance between the deflector and the support plate is minimal, and the airflow velocity across the seam is greater, further improving the deboning success rate and ensuring the successful deboning of the seam at the folded part of the rolled edge fabric. Similarly, in the third step, blowing air into the bone seam of the rolled edge through the air hole can also be blocked and guided by the deflector plate, so that most of the airflow flows in the direction of passing over the bone seam, rather than flowing outward along the bone seam. In this way, the airflow can drive the bone position to flip, thereby achieving bone reversal and further effectively improving the success rate of bone reversal of the remaining bone seams of the rolled edge.

[0009] Preferably, the spacing between the guide plate and the suture of the rolled edge in the first step is set to 3-15 mm.

[0010] Preferably, the distance between the guide vane and the air inlet is 4-12 mm. This distance provides the best airflow guidance effect.

[0011] Preferably, the air-blowing bone-setting device also includes: The guide plate and the reverse bone plate are located on the same side of the mountain. The air blowing hole blows air towards the guide plate. The gap between the guide plate and the reverse bone plate forms a channel to accommodate the bone suture. The gauge plate translation mechanism drives the gauge plate to translate, and the direction of movement of the gauge plate is parallel to the direction of movement of the reverse bone plate.

[0012] The first step also includes a guide plate translation mechanism driving the guide plate to translate, inserting it into a designated position between the upper and lower layers of fabric of the rolled edge. The guide plate spreads the two layers of the rolled edge apart, reducing airflow resistance between them. Thus, in the second step, when air is blown towards the bone suture through the air holes, this reduces airflow resistance between the upper and lower layers, increasing the airflow along the direction across the bone suture and improving the success rate of the bone suture incision.

[0013] The third step is followed by the following steps: Fourth, the gauge plate translation mechanism drives the gauge plate to translate outward from the rolled edge, so that the gauge plate moves outward from the rolled edge.

[0014] As a preferred option, the time t1 is set to 0.5-2 seconds.

[0015] Preferably, when the reverse plate translation mechanism drives the reverse plate to translate outward from the rolled edge, a continuous translation method is used to move the reverse plate outward to the rolled edge.

[0016] Preferably, in the third step, when the reverse plate translation mechanism drives the reverse plate to translate outward from the rolled edge, the reverse plate is moved outward to the rolled edge using a gap translation method. The gap translation method means that the reverse plate translation mechanism drives the reverse plate to translate outward from the rolled edge by a set distance L1 and stops for a set time t2.

[0017] The beneficial effects of this invention are as follows: In the first step, the reverse plate is driven by the reverse plate translation mechanism to insert between the upper and lower layers of fabric of the rolled edge, so that the air blowing hole is close to the folded part of the rolled edge; then in the second step, air is blown into the seam of the rolled edge through the air blowing hole for a set time t1, and the seam of the folded part of the rolled edge is reversed. During this process, the air blowing hole is close to the folded part of the rolled edge fabric, which can effectively improve the success rate of reversing the seam of the folded part of the rolled edge, so that the seam of the folded part of the rolled edge fabric is successfully reversed. Next, in the third step, the reverse plate translation mechanism drives the reverse plate to translate outward from the rolled edge, so that the reverse plate moves out of the rolled edge. During this process, air is blown into the seam of the rolled edge through the air blowing hole, and the seams of the remaining parts of the rolled edge are reversed in sequence, thereby effectively improving the success rate of reversing the seams of the remaining parts of the rolled edge. Therefore, the method of air blowing and rebar insertion for hemmed seams in this solution can effectively improve the success rate of rebar insertion for hemmed seams, thereby effectively solving the problem of affecting sewing quality due to unsuccessful rebar insertion at some seams.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Specific Implementation Example 1, such as Figure 1 As shown, a method for defrosting bone seams by blowing air is used, which involves defrosting the bone using an air-blowing device. The air-blowing device includes a defrosting plate 2 and a defrosting plate translation mechanism 4.

[0025] The reverse bone plate 2 is provided with an air blowing channel and an air blowing hole 2.1 connected to the air blowing channel. In this embodiment, the air blowing channel is located inside the reverse bone plate 2, and the air blowing hole 2.1 is located on the side of the reverse bone plate 2, with the air blowing hole 2.1 close to one end of the reverse bone plate 2.

[0026] The reverse plate translation mechanism 4 drives the reverse plate 2 to translate. The reverse plate translation mechanism 4 is a pneumatic cylinder, an electric cylinder, or a linear module. Of course, the reverse plate translation mechanism 4 can also be other translation mechanisms available on the market.

[0027] The method of inflating and repositioning the rolled-edge bone joints includes the following steps. First, the reverse plate translation mechanism 4 drives the reverse plate 2 to be inserted between the upper and lower layers of fabric of the rolled edge 1, so that the air hole 2.1 is close to the folded part 1.0 of the rolled edge 1.

[0028] Second, pressurized gas is introduced into the air blowing channel and blown through the air blowing hole 2.1 toward the bone seam 1.1 of the rolled edge 1 for a set time t1, thereby reshaping the bone seam 1.1 of the folded part 1.0 of the rolled edge 1. The set time t1 is 0.5-2 seconds. For example, the set time t1 is 0.5 seconds, 0.8 seconds, or 1 second.

[0029] Third, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1 to reverse bone of the remaining bone seams 1.1 of the rolled edge 1. When the reverse bone plate 2 moves outward from the rolled edge 1, the repositioning is completed, and the input of pressurized gas into the air blowing channel stops.

[0030] In the first step of the hem seam blowing and debossing method of this embodiment, the debossing plate 2 is driven to be inserted between the upper and lower layers of fabric of the hem 1 by the debossing plate translation mechanism 4, so that the blowing hole 2.1 is close to the folded part 1.0 of the hem 1.

[0031] Next, in the second step, air is blown through the air hole 2.1 toward the seam 1.1 of the rolled edge 1 for a set time t1, and the seam 1.1 of the folded part 1.0 of the rolled edge 1 is bent. During this process, the air hole 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, which can effectively improve the success rate of bending the seam 1.1 of the folded part 1.0 of the rolled edge 1, so that the seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully bent.

[0032] Next, in the third step, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1, and the bone seams 1.1 of the remaining parts of the rolled edge 1 are reverse boned in sequence, thereby effectively improving the success rate of reversing the bone seams 1.1 of the remaining parts of the rolled edge 1. Therefore, the bone seam blowing reversing method of this embodiment can effectively improve the success rate of reversing the bone seams 1.1 during the sewing process of the rolled edge 1, thereby effectively solving the problem of affecting the sewing quality due to unsuccessful reversing of some bone positions.

[0033] Specific embodiment two, such as Figures 1-4 As shown, a method for defrosting sutures by blowing air is used, which involves defrosting the sutures using an air-blowing defrosting device. The air-blowing defrosting device includes a defrosting plate 2, a defrosting plate translation mechanism 4, a guide plate 3, and a fixed support 7.

[0034] The support plate 7 is used to block the folded part 1.0 of the rolled edge 1. The reinforcing plate 2 is located on one side of the support plate 7.

[0035] The reverse bone plate 2 is provided with an air blowing channel and an air blowing hole 2.1 connected to the air blowing channel. In this embodiment, the air blowing channel is located inside the reverse bone plate 2, and the air blowing hole 2.1 is located on the side of the reverse bone plate 2, with the air blowing hole 2.1 close to one end of the reverse bone plate 2.

[0036] The guide plate 3 is disposed on one side of the inverted plate 2 where the air hole 2.1 is located. The air hole 2.1 is located between the guide plate 3 and the backrest 7, and the guide plate 3 is close to the air hole 2.1. In this embodiment, the distance between the guide plate 3 and the air hole 2.1 is 4-12 mm.

[0037] The reverse plate translation mechanism 4 drives the reverse plate 2 to translate. In this embodiment, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate so that the air inlet 2.1 is closer to or further away from the backing 7. The translation direction of the reverse plate 2 is parallel to the length direction of the bone seam 1.1 of the rolled edge 1. The reverse plate translation mechanism 4 is a cylinder, an electric cylinder, or a linear module. Of course, the reverse plate translation mechanism 4 can also be other translation mechanisms available on the market.

[0038] The method of inflating and repositioning the rolled-edge bone joints includes the following steps. First, such as Figure 1 , Figure 4 As shown, the reverse plate translation mechanism 4 drives the reverse plate 2 to insert between the upper and lower layers of fabric of the rolled edge 1, so that the air inlet 2.1 is close to the folded part 1.0 of the rolled edge 1. The guide plate 3 has a set distance between it and the seam 1.1 of the rolled edge 1, which is 3-15 mm. For example, the distance between the guide plate 3 and the seam 1.1 of the rolled edge 1 is 3 mm, 5 mm, 6 mm or 8 mm.

[0039] Second, such as Figure 1 As shown, pressurized gas is input into the air blowing channel and blown through the air blowing hole 2.1 toward the bone seam 1.1 of the rolled edge 1 for a set time t1, thereby reshaping the bone seam 1.1 of the folded part 1.0 of the rolled edge 1. The set time t1 is 0.5-2 seconds. For example, the set time t1 is 0.5 seconds, 0.8 seconds, or 1 second. In this step, during the blowing of air through the air blowing hole 2.1 toward the bone seam 1.1, under the guiding effect of the backrest 7 and the guide plate 3, when the airflow encounters the bone seam 1.1, the airflow flowing along the direction of the bone seam 1.1 can be reduced, and the airflow flowing across the direction of the bone seam 1.1 can be increased (so that most of the airflow flows across the direction of the bone seam 1.1), thereby causing the bone position to flip, so as to realize the reshaping of the bone seam 1.1 of the folded part 1.0 of the rolled edge 1. Based on this, due to the blocking and guiding effect of the support plate 7 and the guide plate 3, most of the airflow will flow in the direction of passing through the bone seam 1.1, rather than flowing outward along the bone seam 1.1. In this way, the airflow can drive the bone position to flip, realizing the reverse bone, thereby further effectively improving the success rate of reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1, and ensuring that the reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully completed. At the same time, during this process, the air hole 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, the distance between the guide plate 3 and the support plate 7 is the smallest, and the airflow velocity across the bone seam 1.1 is greater, thereby further improving the success rate of reverse bone, and ensuring that the reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully completed.

[0040] In the text, the airflow flowing along the direction of suture 1.1 refers to the airflow flowing along the length direction of suture 1.1 under the guidance of suture 1.1; Airflow flowing in the direction passing through suture 1.1 refers to airflow flowing in a direction perpendicular to the length of suture 1.1.

[0041] Third, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1 to reverse bone seam 1.1 in the remaining parts of the rolled edge 1. When the reverse bone plate 2 moves outward from the rolled edge 1, the repositioning is completed, and the input of pressurized gas into the air blowing channel stops. In this step, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1. Alternatively, the obstruction and guiding effect of the guide plate 3 can cause most of the airflow to flow in the direction of passing over the bone seam 1.1, rather than flowing outward along the bone seam 1.1. In this way, the airflow can drive the bone position to flip, thereby achieving repositioning and further effectively improving the success rate of repositioning the bone seam 1.1 in the remaining parts of the rolled edge 1.

[0042] In the first step of the hem seam blowing and debossing method of this embodiment, the debossing plate 2 is driven to be inserted between the upper and lower layers of fabric of the hem 1 by the debossing plate translation mechanism 4, so that the blowing hole 2.1 is close to the folded part 1.0 of the hem 1.

[0043] Next, in the second step, air is blown through the air inlet 2.1 towards the seam 1.1 of the rolled edge 1 for a set time t1, and the seam 1.1 of the folded part 1.0 of the rolled edge 1 is re-bonded. During this process, the air inlet 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, which can effectively improve the success rate of re-bonding the seam 1.1 of the folded part 1.0 of the rolled edge 1, so that the seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully re-bonded. On the other hand, due to the blocking and guiding effect of the backrest 7 and the guide plate 3, most of the airflow will flow in the direction of passing the seam 1.1, rather than flowing outward along the direction of the seam 1.1. In this way, the airflow can drive the bone position to flip, thereby realizing the re-bonding, and further effectively improving the success rate of re-bonding the seam 1.1 of the folded part 1.0 of the rolled edge 1, so that the seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully re-bonded. At the same time, during this process, the air blowing hole 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, the distance between the guide plate 3 and the backing 7 is the smallest, and the airflow speed across the bone seam 1.1 is greater, which can further improve the success rate of the reverse bone, so that the bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric can be successfully reversed.

[0044] Next, in the third step, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1, and the remaining bone seams 1.1 of the rolled edge 1 are deboned in sequence, thereby effectively improving the success rate of deboning the remaining bone seams 1.1 of the rolled edge 1. At the same time, the obstruction and guidance effect of the guide plate 3 can also make most of the airflow flow in the direction of passing over the bone seam 1.1, rather than flowing outward along the bone seam 1.1, thereby further effectively improving the success rate of deboning the remaining bone seams 1.1 of the rolled edge 1.

[0045] Therefore, the method of blowing and deboning the seam of the rolled edge in this embodiment can effectively improve the success rate of deboning the seam 1.1 during the rolling edge 1 sewing process, thereby effectively solving the problem of affecting the sewing quality due to the failure of deboning some seam positions.

[0046] In one embodiment of this invention, in the third step, when the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1, a continuous translation method is used to move the reverse plate 2 outwards from the rolled edge 1. For example, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 at a uniform speed.

[0047] In another embodiment of this invention, in the third step, when the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1, a gap translation method is used to move the reverse plate 2 outwards from the rolled edge 1. The gap translation method means that the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 for a set distance L1, and then stops for a set time t2. For example, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 at a constant speed for a set distance L1, where the set distance L1 is 1 cm; and stops for a set time t2, which is 0.2-1 second.

[0048] Specific embodiment three, such as Figures 1-4 As shown, a method for air-blowing and deboning a rolled-edge bone seam uses an air-blowing and deboning device. The air-blowing and deboning device includes a deboning plate 2, a deboning plate translation mechanism 4, a gauge plate 5, a gauge plate translation mechanism 6, a guide plate 3, and a fixed support 7.

[0049] The support plate 7 is used to block the folded part 1.0 of the rolled edge 1. The reinforcing plate 2 is located on one side of the support plate 7.

[0050] The reverse bone plate 2 is provided with an air blowing channel and an air blowing hole 2.1 connected to the air blowing channel. In this embodiment, the air blowing channel is located inside the reverse bone plate 2, and the air blowing hole 2.1 is located on the side of the reverse bone plate 2, with the air blowing hole 2.1 close to one end of the reverse bone plate 2.

[0051] The guide plate 3 is disposed on one side of the inverted plate 2 where the air hole 2.1 is located. The air hole 2.1 is located between the guide plate 3 and the backrest 7, and the guide plate 3 is close to the air hole 2.1. In this embodiment, the distance between the guide plate 3 and the air hole 2.1 is 4-12 mm.

[0052] The reverse plate translation mechanism 4 drives the reverse plate 2 to translate. In this embodiment, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate so that the air inlet 2.1 is closer to or further away from the backing 7. The translation direction of the reverse plate 2 is parallel to the length direction of the bone seam 1.1 of the rolled edge 1. The reverse plate translation mechanism 4 is a cylinder, an electric cylinder, or a linear module. Of course, the reverse plate translation mechanism 4 can also be other translation mechanisms available on the market.

[0053] The guide plate 5 and the reverse bone plate 2 are located on the same side as the backrest 7. Air is blown into the guide plate 5 once through the air inlet 2.1. The gap between the guide plate 5 and the reverse bone plate 2 forms a receiving channel to accommodate the bone suture 1.1. In this embodiment, the guide plate 5 and the reverse bone plate 2 are parallel, and the reverse bone plate 2 is horizontally distributed.

[0054] The gauge plate translation mechanism 6 drives the gauge plate 5 to translate, and the direction of movement of the gauge plate 5 is parallel to the direction of movement of the reverse plate 2. In this embodiment, the reverse plate 2 moves horizontally. The gauge plate translation mechanism 6 is a pneumatic cylinder, an electric cylinder, or a linear module. Of course, the gauge plate translation mechanism 6 can also be other translation mechanisms available on the market.

[0055] The method of inflating and repositioning the rolled-edge bone joints includes the following steps. First, such as Figure 1 , Figure 4 As shown, the reverse plate translation mechanism 4 drives the reverse plate 2 to insert between the upper and lower layers of fabric of the rolled edge 1, so that the air inlet 2.1 is close to the folded part 1.0 of the rolled edge 1. The guide plate 3 has a set distance between it and the seam 1.1 of the rolled edge 1, which is 3-15 mm. For example, the distance between the guide plate 3 and the seam 1.1 of the rolled edge 1 is 3 mm, 5 mm, 6 mm or 8 mm.

[0056] The guide plate translation mechanism 6 drives the guide plate 5 to translate, so that the guide plate 5 is inserted into the designated position between the upper and lower layers of fabric of the hem 1. The guide plate 5 opens up the two layers of the hem 1 to reduce the flow resistance of air between the upper and lower layers of fabric of the hem 1. The suture 1.1 of the hem 1 is located in the receiving channel between the guide plate 5 and the reverse suture plate 2.

[0057] Second, such as Figure 1As shown, pressurized gas is input into the air blowing channel and blown through the air blowing hole 2.1 toward the bone seam 1.1 of the rolled edge 1 for a set time t1, thereby reshaping the bone seam 1.1 of the folded part 1.0 of the rolled edge 1. The set time t1 is 0.5-2 seconds. For example, the set time t1 is 0.5 seconds, 0.8 seconds, or 1 second. In this step, during the blowing of air through the air blowing hole 2.1 toward the bone seam 1.1, under the guiding effect of the backrest 7 and the guide plate 3, when the airflow encounters the bone seam 1.1, the airflow flowing along the direction of the bone seam 1.1 can be reduced, and the airflow flowing across the direction of the bone seam 1.1 can be increased (so that most of the airflow flows across the direction of the bone seam 1.1), thereby causing the bone position to flip, so as to realize the reshaping of the bone seam 1.1 of the folded part 1.0 of the rolled edge 1. Based on this, due to the blocking and guiding effect of the support plate 7 and the guide plate 3, most of the airflow will flow in the direction of passing through the bone seam 1.1, rather than flowing outward along the bone seam 1.1. In this way, the airflow can drive the bone position to flip, realizing the reverse bone, thereby further effectively improving the success rate of reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1, and ensuring that the reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully completed. At the same time, during this process, the air hole 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, the distance between the guide plate 3 and the support plate 7 is the smallest, and the airflow velocity across the bone seam 1.1 is greater, thereby further improving the success rate of reverse bone, and ensuring that the reverse bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully completed.

[0058] Third, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1 to reverse bone seam 1.1 in the remaining parts of the rolled edge 1. When the reverse bone plate 2 moves outward from the rolled edge 1, the repositioning is completed, and the input of pressurized gas into the air blowing channel stops. In this step, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1. Alternatively, the obstruction and guiding effect of the guide plate 3 can cause most of the airflow to flow in the direction of passing over the bone seam 1.1, rather than flowing outward along the bone seam 1.1. In this way, the airflow can drive the bone position to flip, thereby achieving repositioning and further effectively improving the success rate of repositioning the bone seam 1.1 in the remaining parts of the rolled edge 1.

[0059] Fourth, the gauge plate translation mechanism 6 drives the gauge plate 5 to translate outward from the rolled edge 1, so that the gauge plate 5 moves outward from the rolled edge 1.

[0060] In the first step of the hem seam blowing and repositioning method of this embodiment, the repositioning plate 2 is driven by the repositioning plate translation mechanism 4 to be inserted between the upper and lower layers of fabric of the hem 1, so that the air blowing hole 2.1 is close to the folded part 1.0 of the hem 1. The guide plate translation mechanism 6 drives the guide plate 5 to translate, so that the guide plate 5 is inserted into a designated position between the upper and lower layers of fabric of the hem 1. The guide plate 5 opens up the two layers of the hem 1 to reduce the flow resistance of airflow between the upper and lower layers of fabric of the hem 1.

[0061] Next, in the second step, air is blown through the air inlet 2.1 towards the seam 1.1 of the rolled edge 1 for a set time t1, and the seam 1.1 of the folded part 1.0 of the rolled edge 1 is re-bonded. During this process, the air inlet 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, which can effectively improve the success rate of re-bonding the seam 1.1 of the folded part 1.0 of the rolled edge 1, so that the seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully re-bonded. On the other hand, due to the blocking and guiding effect of the backrest 7 and the guide plate 3, most of the airflow will flow in the direction of passing the seam 1.1, rather than flowing outward along the direction of the seam 1.1. In this way, the airflow can drive the bone position to flip, thereby realizing the re-bonding, and further effectively improving the success rate of re-bonding the seam 1.1 of the folded part 1.0 of the rolled edge 1, so that the seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric is successfully re-bonded. At the same time, during this process, the air blowing hole 2.1 is close to the folded part 1.0 of the rolled edge 1 fabric, the distance between the guide plate 3 and the backing 7 is the smallest, and the airflow speed across the bone seam 1.1 is greater, which can further improve the success rate of the reverse bone, so that the bone seam 1.1 of the folded part 1.0 of the rolled edge 1 fabric can be successfully reversed.

[0062] Next, in the third step, the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to translate outward from the rolled edge 1, so that the reverse bone plate 2 moves outward from the rolled edge 1. During this process, air is blown into the bone seam 1.1 of the rolled edge 1 through the air blowing hole 2.1, and the remaining bone seams 1.1 of the rolled edge 1 are deboned in sequence, thereby effectively improving the success rate of deboning the remaining bone seams 1.1 of the rolled edge 1. At the same time, the obstruction and guidance effect of the guide plate 3 can also make most of the airflow flow in the direction of passing over the bone seam 1.1, rather than flowing outward along the bone seam 1.1, thereby further effectively improving the success rate of deboning the remaining bone seams 1.1 of the rolled edge 1.

[0063] Therefore, the method of blowing and deboning the seam of the rolled edge in this embodiment can effectively improve the success rate of deboning the seam 1.1 during the rolling edge 1 sewing process, thereby effectively solving the problem of affecting the sewing quality due to the failure of deboning some seam positions.

[0064] In one embodiment of this invention, in the third step, when the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1, a continuous translation method is used to move the reverse plate 2 outwards from the rolled edge 1. For example, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 at a uniform speed.

[0065] In another embodiment of this invention, in the third step, when the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1, a gap translation method is used to move the reverse plate 2 outwards from the rolled edge 1. The gap translation method means that the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 for a set distance L1, and then stops for a set time t2. For example, the reverse plate translation mechanism 4 drives the reverse plate 2 to translate outwards from the rolled edge 1 at a constant speed for a set distance L1, where the set distance L1 is 1 cm; and stops for a set time t2, which is 0.2-1 second.

[0066] In specific embodiment four, the method of inflating and retracting the bone along the rolled edge refers to specific embodiment one, two, or three, with the difference being... like Figure 2 , Figure 3 As shown, the air-blowing bone-setting device also includes a frame. The support 7 is fixed to the frame. For example, the support 7 is fixed to the frame by bolts. This facilitates the installation and fixation of the support 7.

[0067] The side of the support plate 7 facing the reversed plate 2 has vertically distributed support surfaces 7.1. Support surfaces 7.1 are perpendicular to the moving direction of the reversed plate 2. Support surfaces 7.1 are used to block the folded portion 1.0 of the rolled edge 1. Air inlets 2.1 blow air along the direction of the support surfaces 7.1. The guide plate 3 is parallel to the support surfaces 7.1. Support surfaces 1.1 are perpendicular to the moving direction of the reversed plate 2.

[0068] Furthermore, the air-blowing bone-reversing device also includes a support frame. The support frame and the machine frame are manufactured separately and then connected as a single unit by welding or studs; alternatively, the support frame and the machine frame can be integrally formed. A horizontal guide rail 8 is provided on the support frame, and a bone-reversing plate slide seat 9 is slidably mounted on the horizontal guide rail 8. The bone-reversing plate 2 is fixedly mounted on the bone-reversing plate slide seat 9. A bone-reversing plate translation mechanism 4 is mounted on the support frame. The bone-reversing plate translation mechanism 4 drives the bone-reversing plate slide seat 9 to slide along the horizontal guide rail 8, thereby causing the bone-reversing plate 2 to translate.

[0069] In this embodiment, as Figure 2 As shown, there are two horizontal guide rails 8, which are parallel to each other. A reverse bone plate slide 9 is slidably mounted on one horizontal guide rail 8; a gauge plate slide 10 is slidably mounted on the other horizontal guide rail 8, and the gauge plate 5 is fixedly mounted on the gauge plate slide 10. The gauge plate translation mechanism 6 drives the gauge plate slide 10 to slide along the horizontal guide rail 8, thereby causing the gauge plate 5 to translate.

[0070] Furthermore, such as Figure 2 As shown, the boning plate 2 is elongated, and its length direction is parallel to its moving direction. An air inlet 2.1 is located on one side of the end of the boning plate 2. This facilitates the insertion of the boning plate 2 between the upper and lower layers of fabric of the hem 1.

[0071] Furthermore, the air blowing channel is a smoothly transitioned channel, with a pipe interface at one end connecting to an air supply pipe. This allows for smoother airflow within the air blowing channel, reducing flow resistance. The air supply pipe introduces pressurized gas into the air blowing channel.

[0072] Furthermore, such as Figure 2 As shown, the lower surface of the guide plate 5 is provided with a guide notch 5.1. The guide notch 5.1 is located on the side of the guide plate 5 near the aforementioned support 7 and extends through the lower surface of the guide plate 5. The air blowing hole 2.1 blows air in the direction of the guide notch 5.1. In this way, after the guide plate 5 is inserted between the upper and lower layers of fabric of the hem 1, the space for airflow can be further increased through the guide notch 5.1 without affecting the guide plate 5's ability to support the fabric of the hem 1. This further reduces the flow resistance of airflow between the upper and lower layers of fabric of the hem 1, so that subsequent airflow can flow in the direction of passing through the bone seam 1.1, thereby helping to further improve the success rate of bone seam 1.1.

[0073] Furthermore, such as Figure 5 As shown, the air-blowing bone-setting device also includes: A guide hole 3.1 is provided inside the guide plate 3 and connected to the air blowing channel. The guide hole 3.1 extends along the air blowing direction of the inverted bone air blowing hole 2.1. The reverse bone pusher 12 is slidably disposed within the guide through hole 3.1; The magnet 11 is fixedly installed; In the first step, before the reverse bone plate translation mechanism 4 drives the reverse bone plate 2 to move, the reverse bone plate 2 is located outside the rolled edge 1. At this time, the magnet 11 and the reverse bone pusher 12 are distributed opposite each other. The reverse bone pusher 12 moves into the guide through hole 3.1 under the attraction of the magnet.

[0074] The reverse plate translation mechanism 4 drives the reverse plate 2 to be inserted between the upper and lower layers of fabric of the rolled edge 1, so that the air hole 2.1 is close to the folded part 1.0 of the rolled edge 1; at this time, the magnet 11 and the reverse pusher 12 are staggered.

[0075] In the second step, when pressurized gas is introduced into the air blowing channel, the reverse bone pusher 12 moves outward along the guide hole 3.1 under the action of the pressurized gas, and pushes the bone seam 1.1 to rotate at a set angle. Based on this, in the first step, since the reverse bone pusher 12 is located inside the guide hole 3.1, the reverse bone pusher 12 will not contact the bone seam 1.1, and therefore will not affect the normal insertion of the reverse bone plate 2 between the upper and lower layers of fabric of the rolled edge 1, and will not affect the position of the rolled edge 1 and the bone seam 1.1.

[0076] In the second step, the reverse-bone pusher 12 moves outward along the guide hole 3.1 under the action of pressurized gas. In this way, on the one hand, the reverse-bone pusher 12 can directly push the bone seam 1.1 to flip a certain angle, and the reverse-bone pusher 12 abuts against the bone seam 1.1. At the same time, some airflow blows towards the bone seam 1.1 through the gap between the guide hole 3.1 and the reverse-bone pusher 12. On the other hand, the reverse-bone pusher 12 can also block and guide the airflow in conjunction with the guide plate 3, so that most of the airflow flows in the direction of passing over the bone seam 1.1, rather than flowing outward along the bone seam 1.1. This, together with the airflow, drives the bone position to flip, further improving the success rate of reverse-boneing the bone seam 1.1 of the folded part 1.0 of the rolled edge fabric.

[0077] In the third step, the reverse bone pusher 12 can directly push the bone joint 1.1 to rotate at a certain angle. At the same time, some airflow blows towards the bone joint 1.1 through the gap between the guide hole 3.1 and the reverse bone pusher 12, causing the bone joint 1.1 to fold up, so as to avoid the reverse bone pusher 12 pressing on the bone joint 1.1. On the other hand, the reverse bone pusher 12 can also block and guide the airflow in conjunction with the guide plate 3, so that most of the airflow flows in the direction of passing over the bone joint 1.1, rather than flowing outward along the bone joint 1.1. This, in conjunction with the airflow, drives the bone position to rotate, further improving the success rate of the reverse bone joint 1.1. When the reverse plate translation mechanism 4 drives the reverse plate 2 to move away from the backing 7 and into position, the reverse plate 2 moves out to the outside of the rolled edge 1, the reverse plate is finished, and then the pressure gas is stopped entering the air blowing channel; at this time, the magnet and the reverse plate pusher 12 are distributed opposite each other, and the reverse plate pusher 12 moves into the guide hole 3.1 under the attraction of the magnet, in preparation for the next reverse plate.

[0078] Specifically, such as Figure 5 As shown, the guide hole 3.1 extends along the blowing direction of the air blowing hole 2.1. The guide hole 3.1 is horizontally distributed. The guide hole 3.1 is parallel to the backing surface 7.1. The magnet 11 is fixedly mounted on the frame, and the magnet 11 is displaced at the same height as the guide hole 3.1. The magnet 11 is located on the outside of the reverse plate 2, and the magnet and the guide plate 3 are located on opposite sides of the reverse plate 2. The magnet 11 is an electromagnet or a permanent magnet. The magnet can attract the reverse pusher 12, for example, the reverse pusher 12 is provided with a magnetic attraction element, which is a permanent magnet or an iron part; or the reverse pusher 12 is entirely made of iron.

[0079] Furthermore, such as Figure 5 As shown, a guide groove 13 extending axially along the guide through hole 3.1 is provided on the inner wall of the guide through hole 3.1. The reverse bone pusher 12 is provided with a limiting slider 14 that cooperates with the guide groove. The limiting slider extends into the guide groove to limit the sliding stroke of the reverse bone pusher 12 along the guide through hole 3.1.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
