Description

Technical Field

[0001] This invention relates to the field of sewing equipment, and more specifically, to an adaptive correction device. Background Technology

[0002] Overlock sewing equipment typically requires a correction device at its front end to correct the positional deviation of the fabric sewing edge in real time during the sewing process, ensuring that the sewing stitches maintain a constant distance from the fabric edge, thereby improving sewing quality and consistency.

[0003] Existing correction devices generally include an upper correction mechanism and a lower correction mechanism arranged opposite each other. During the sewing process, the two are in a closed state, pressing and correcting the upper and lower layers of fabric respectively; while when the fabric is fed, the upper and lower correction mechanisms are separated and in an open state to provide sufficient space for the fabric to pass through.

[0004] However, since the overlock sewing device is typically narrower at the top and wider at the bottom, there is a risk of interference with the lower body of the overlock sewing device when the lower correction mechanism moves downwards away from the upper correction mechanism during opening. To avoid collisions, existing correction mechanisms have to be positioned horizontally at a considerable distance from the overlock sewing device, resulting in a larger distance between the correction mechanism and the sewing needle. This makes the fabric susceptible to pulling or shifting during transport from the correction position to the needle, hindering the effective transfer of correction and consequently affecting sewing quality. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive correction device that can be arranged close to the overlock sewing device and prevent the lower correction mechanism from interfering with the machine body below the overlock sewing device during the opening process, thereby significantly improving the sewing quality.

[0010] In an optional embodiment, the connecting seat is provided with a limiting part, and the correcting body is provided with a mating part. The limiting part is used to stop the mating part to limit the angle at which the correcting body deflects toward the overlocking device.

[0011] In an optional embodiment, the guiding assembly includes a cantilever and a guiding shaft. One end of the cantilever is connected to the correction body, and the other end extends near the overlock device and is suspended in the air.

[0014] In an optional embodiment, the adaptive correction device further includes a partition plate disposed on the main body of the device and positioned between the upper correction mechanism and the lower correction mechanism.

Therefore, the beneficial effects of the adaptive correction device provided by this invention include: it can be arranged close to the overlock sewing device and prevents the lower correction mechanism from interfering with the machine body below the overlock sewing device during opening, thus significantly improving sewing quality.

[0026] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a schematic representation of the adaptive correction device 100 provided in this embodiment in a practical application. Figure 2 As shown Figure 1 An enlarged schematic diagram of region A in the middle.

[0028] The adaptive correction device 100 provided in this embodiment is set on the front side of the overlock sewing device 200 in practical applications. It can correct the positional deviation of the fabric sewing edge in real time during the sewing process, ensuring that the sewing stitch and the fabric edge maintain a constant distance, thereby improving the sewing quality and consistency.

[0029] The adaptive correction device 100 includes an upper correction mechanism 120 and a lower correction mechanism 130 arranged opposite each other, and a partition 150 located between the upper correction mechanism 120 and the lower correction mechanism 130. In practical applications, the upper fabric is located between the partition 150 and the upper correction mechanism 120, and the upper correction mechanism 120 corrects the deviation of the upper fabric; the lower fabric is located between the partition 150 and the lower correction mechanism 130, and the lower correction mechanism 130 corrects the deviation of the lower fabric. The overlock sewing device 200 sews the corresponding seam edges of the upper and lower fabrics together.

[0030] During the sewing process, the upper correction mechanism 120 and the lower correction mechanism 130 move closer to each other, as if... Figure 2 The closed state shown corrects the deviation of the upper and lower fabric layers respectively. When the fabric is fed, the upper correction mechanism 120 and the lower correction mechanism 130 move separately to the open state, that is, the upper correction mechanism 120 moves upward and forms a space between itself and the partition 150 for the upper fabric layer to pass through; the lower correction mechanism 130 moves downward and forms a space between itself and the partition 150 for the lower fabric layer to pass through.

[0031] Please refer to the following: Figures 3 to 6 , Figure 3 The diagram shown is a structural schematic of the adaptive correction device 100. Figure 4 As shown Figure 3 Enlarged diagram of region B in the middle. Figure 5 The diagram shown is a schematic representation of the lower correction mechanism 130 from one perspective. Figure 6 The diagram shown is a structural schematic of the lower correction mechanism 130 from another perspective.

[0032] In this embodiment, the adaptive correction device 100 further includes a device body 110 and a drive mechanism 140. The upper correction mechanism 120 and the lower correction mechanism 130 are rotatably mounted on the device body 110. The drive mechanism 140 is mounted on the device body 110 and is drively connected to the upper correction mechanism 120 and the lower correction mechanism 130. In practical applications, the drive mechanism 140 can drive the upper correction mechanism 120 and the lower correction mechanism 130 to simultaneously deflect in opposite directions in the vertical direction, so that the upper correction mechanism 120 and the lower correction mechanism 130 move closer to each other to achieve a closed state, or move further apart to achieve an open state.

[0033] Since the overlock sewing device 200 typically has a structure that is narrower at the top and wider at the bottom, there is a risk of interference with the lower body of the overlock sewing device 200 when the lower correction mechanism 130 moves downward away from the upper correction mechanism 120 during the opening process. In order to ensure that the adaptive correction device 100 is positioned as close as possible to the overlock sewing device 200 and to avoid collision between the lower correction mechanism 130 and the overlock sewing device 200 during the movement from the closed state to the open state, in this embodiment, the lower correction mechanism 130 includes a connecting seat 131 and a correction body 132. The correction body 132 is rotatably mounted on the connecting seat 131, and the connecting seat 131 is rotatably mounted on the device body 110 and is connected to the drive mechanism 140 for transmission. Under the drive of the drive mechanism 140, the correction body 132 is driven to deflect in a direction closer to or away from the upper correction mechanism 120.

[0034] Furthermore, the correction body 132 is provided with a guide component 133, which is configured to slide in contact with the overlock device 200 during the process of the correction body 132 deflecting away from the upper correction mechanism 120, and drive the correction body 132 to deflect away from the connecting seat 131 in a direction away from the overlock device 200 under the contact reaction force.

[0035] Understandably, during the downward deflection of the connecting seat 131 driven by the driving mechanism 140, the guiding component 133 is closer to the overlock sewing device 200 than the correcting body 132 along the deflection path. That is, the guiding component 133 contacts the overlock sewing device 200 before the correcting body 132 and slides on the surface of the overlock sewing device. During this process, the guiding component 133 receives a contact reaction force from the overlock sewing device 200, and under this contact reaction force, drives the correcting body 132 to deflect away from the connecting seat 131 in a direction away from the overlock sewing device 200, thus achieving avoidance of the overlock sewing device 200 by the correcting body 132 and preventing collision.

[0036] Specifically, the upper correction mechanism 120 is provided with a drive gear 121, and the connecting seat 131 is provided with a driven gear 135 that meshes with the drive gear 121. The drive mechanism 140 is connected to the connecting seat 131 through the upper correction mechanism 120.

[0037] It is understandable that the rotation center line of the driving gear 121 and the upper correction mechanism 120 are set coaxially, and the rotation center line of the driven gear 135 and the connecting seat 131 are set coaxially. When the driving mechanism 140 drives the upper correction mechanism 120 to rotate, the upper correction mechanism 120 drives the driving gear 121 and the driven gear 135 to rotate synchronously. The driven gear 135 then drives the connecting seat 131 to rotate synchronously, thereby causing the correction body 132 to deflect in the direction of approaching or moving away from the upper correction mechanism 120.

[0038] The upper correction mechanism 120 is equipped with an upper correction motor 122, an upper correction wheel 123, an upper fabric feeding motor 124, and an upper fabric feeding wheel 125. The upper correction motor 122 is connected to the upper correction wheel 123, and the upper fabric feeding motor 124 is connected to the upper fabric feeding wheel 125.

[0039] In practical applications, both the upper correction wheel 123 and the upper feed wheel 125 press against the surface of the upper fabric. The upper feed motor 124 drives the upper feed wheel 125 to rotate, thereby feeding the upper fabric to the overlock sewing device 200. The upper correction motor 122 drives the upper correction wheel 123 to rotate. The rotation plane of the upper correction wheel 123 forms an angle with the feeding direction of the upper fabric, thereby causing the upper fabric to swing during the feeding process, thus achieving correction of the upper fabric.

[0040] The correction body 132 is equipped with a lower correction motor 136, a lower correction wheel 137, a lower fabric feeding motor 138, and a lower fabric feeding wheel 139. The lower correction motor 136 is connected to the lower correction wheel 137, and the lower fabric feeding motor 138 is connected to the lower fabric feeding wheel 139.

[0041] Similarly, in practical applications, both the lower correction wheel 137 and the lower feed wheel 139 press against the surface of the lower fabric. The lower feed motor 138 drives the lower feed wheel 139 to rotate, thereby feeding the lower fabric to the overlock sewing device 200. The lower correction motor 136 drives the lower correction wheel 137 to rotate. The rotation plane of the lower correction wheel 137 forms an angle with the feeding direction of the lower fabric, thereby causing the lower fabric to swing during the feeding process, thus achieving correction of the lower fabric.

[0042] Preferably, the driving device in this embodiment includes a cylinder, with its fixed end hinged to the main body 110 and its telescopic end hinged to the upper correction mechanism 120. During the switching process between the upper correction mechanism 120 and the lower correction mechanism 130 from a closed state to an open state, the cylinder pulls the upper correction mechanism 120 to rotate upward; during the switching process between the upper correction mechanism 120 and the lower correction mechanism 130 from an open state to a closed state, the cylinder pushes the upper correction mechanism 120 to rotate downward.

[0043] In practical applications, the main body 110 of the device is located on one side of the overlock sewing device 200 in the first horizontal direction, that is, the overlock sewing device 200 is located on one side of the upper correction mechanism 120 and the lower correction mechanism 130 in the first horizontal direction. Figure 1 The direction indicated by the X-arrow is the first horizontal direction.

[0044] The rotation center line of the connecting seat 131 relative to the device body 110 extends in the first horizontal direction and is parallel to the rotation center line of the upper correction mechanism 120 relative to the device body 110, as well as parallel to the rotation center line of the fixed end of the cylinder relative to the device body 110 and parallel to the rotation center line of the telescopic end relative to the upper correction mechanism 120.

[0045] The rotation center line of the correction body 132 relative to the connecting seat 131 extends in the second horizontal direction. Figure 3 The direction indicated by the Y-arrow is the second horizontal direction. In this embodiment, the first horizontal direction is perpendicular to the second horizontal direction. In fact, in... Figure 1 In the state shown, the first horizontal direction is the left-right direction, and the second horizontal direction is the front-back direction. The adaptive correction device 100 is located on the left side of the overlock sewing device 200.

[0046] In other words, when the cylinder pulls the correction mechanism 120 upward, the connecting seat 131 is driven to deflect downward through the meshing of the driving gear 121 and the driven gear 135. During this process, under the contact reaction force applied by the overlock device 200, the guide assembly 133 drives the correction body 132 to deflect to the right relative to the connecting seat 131 to avoid the overlock device 200 located to its left.

[0047] In this embodiment, a rotating shaft portion 1321 extending in the second horizontal direction is provided on one side of the correction body 132. A bearing is provided on the connecting seat 131. The bearing is sleeved on the outer side wall of the rotating shaft portion 1321 and connected to the rotating shaft portion 1321.

[0048] Furthermore, an elastic reset member 134 is provided between the connecting seat 131 and the correction body 132. The elastic reset member 134 is configured to drive the correction body 132 to deflect relative to the connecting seat 131 toward the direction of the correction body 200 when the guide component 133 disengages from the overlock device 200.

[0049] Preferably, in this embodiment, the elastic reset member 134 is a torsion spring, which is sleeved on the rotating shaft 1321, and the two ends of the torsion spring abut against the connecting seat 131 and the correction body 132 respectively.

[0050] In order to limit the rotation of the correction body 132, in this embodiment, the connecting seat 131 is provided with a limiting part 1311 and the correction body 132 is provided with a mating part 1322. The limiting part 1311 is used to stop the mating part 1322 to limit the angle of the correction body 132 deflection toward the direction of the overlock sewing device 200.

[0051] In practical applications, after the fabric is fed, when the cylinder pushes the upper correction mechanism 120 to deflect downwards, the connecting seat 131 is driven to deflect upwards through the meshing of the driving gear 121 and the driven gear 135. During this process, the contact reaction force on the guide component 133 gradually decreases, and the torsion spring gradually releases its elastic potential energy, driving the correction body 132 to gradually deflect to the left relative to the connecting seat 131. When the contact reaction force on the guide component 133 is zero, the limiting part 1311 and the mating part 1322 abut against each other, thereby positioning the correction body 132. At this time, the correction body 132 is in the initial angular position when moving from the closed state to the open state.

[0052] In this embodiment, the guide component 133 includes a cantilever 1331 and a guide shaft 1332. One end of the cantilever 1331 is connected to the correction body 132, and the other end extends close to the overlock sewing device 200 and is suspended in the air. The guide shaft 1332 is rotatably disposed at the end of the cantilever 1331 away from the correction body 132 for sliding contact with the overlock sewing device 200. The guide shaft 1332 extends in the second horizontal direction.

[0053] It is understandable that during the sliding contact between the guide shaft 1332 and the overlock device 200, the guide shaft 1332 can rotate relative to the cantilever 1331, thereby reducing the friction between the guide shaft 1332 and the overlock device 200 and ensuring that the adaptive correction device 100 can smoothly switch between the closed state and the open state.

[0054] In summary, the adaptive correction device 100 provided in this embodiment can be positioned close to the overlock sewing device 200, thereby significantly improving the sewing quality.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
