Description

Technical Field

[0001] The present invention belongs to the technical field of sewing machines, and particularly relates to a fabric folding and shaping mechanism for a sleeve placket machine. Background Art

[0002] With the advancement of the automation process in the sewing machine field, in the prior art, there already exists a fabric folding and shaping mechanism for a sleeve placket machine, which replaces manual labor with a machine to perform the folding and shaping process of the sleeve placket. However, in the prior art, generally after the fabric of the sleeve placket is clamped by the folding clip in the folding component, the folding clip is driven by a flipping motor to flip upwards for folding. In this case, the back of the sword head of the sleeve placket faces upwards. If sewn directly, it will result in the sleeve placket being sewn from the back, with neat stitches appearing behind the sleeve placket, while the stitches on the sword head of the sleeve placket that need to be shown will be relatively messy, which does not conform to actual use. In order to ensure that the sleeve placket is sewn from the front, the operator needs to manually turn over the sleeve placket that has been folded upwards so that the sword head faces upwards for sewing. This not only affects the working speed of the sleeve placket machine but also wastes manpower and material resources. Summary of the Invention

[0003] In view of the above defects, the present invention provides a fabric folding and shaping mechanism for a sleeve placket machine. The lifting component controls the lifting operation of the folding component, and the flipping motor can drive the fabric of the sleeve placket to flip downwards for folding. The sword head of the sleeve placket can be kept facing upwards for sewing, which not only improves the working efficiency of the sleeve placket machine but also saves manpower and material resources.

[0004] In order to achieve the above invention object, the present invention provides the following technical solutions:

[0005] A fabric folding and shaping mechanism for a sleeve placket machine, comprising a folding component, a lifting component, and a working cavity, wherein:

[0006] The folding component includes a flipping motor, a flipping motor seat, a first clamping cylinder, a second clamping cylinder, an upper clamping piece, a first lower clamping piece, a positioning piece, and a second lower clamping piece. The flipping motor is installed on the flipping motor seat, and the output end of the flipping motor passes through the flipping motor seat and is connected to the first clamping cylinder. The upper clamping piece and the first lower clamping piece are installed on the first clamping cylinder, the positioning piece and the second lower clamping piece are installed on the second clamping cylinder, and the first clamping cylinder controls one end of the upper clamping piece to tilt up or press down on the first lower clamping piece;

[0007] The lifting component includes a lifting motor, a lifting screw rod seat, a lifting connector, and a folding adjustment seat. The lifting motor is installed on the folding adjustment seat, the lifting screw rod seat is installed on the folding adjustment seat, a screw rod is arranged inside the lifting screw rod seat, the screw rod is connected to the output end of the lifting motor, and the lifting connector is installed on the screw rod;

[0008] The working cavity includes a positioning template and a suction seat, and a negative pressure chamber is arranged inside the suction seat;

[0009] The lifting connector is fixedly connected to the flipping motor base. The flipping motor is installed on the flipping motor base through the folding material adjusting seat, and the positioning piece corresponds to the positioning template.

[0010] Preferably, a drawing component is further arranged below the working cavity. The drawing component includes a support seat, a linear bearing, a linear shaft, and a linear shaft seat. The linear bearing is installed on the support seat. The linear shaft passes through the linear bearing and is connected to the linear shaft seat. The support seat is installed at the bottom of the air suction seat. The linear shaft seat is connected to the folding material adjusting seat. The linear shaft can perform a drawing movement within the linear bearing, thereby driving the linear shaft seat to perform a drawing movement. The linear shaft seat is connected to the folding material adjusting seat, and the folding material adjusting seat drives the folding component to perform a drawing movement. After the folding of the sleeve placket fabric is completed, the drawing component drives the folding component to be withdrawn from the sleeve placket fabric, and the folded sleeve placket fabric proceeds to the next process.

[0011] Preferably, an intermediate separator is further arranged at the bottom of the first lower clamping piece. The intermediate separator is installed on the first clamping air cylinder through the intermediate separator seat. The intermediate separator can separate the first lower clamping piece and the second lower clamping piece during the flipping process, providing a buffering effect.

[0012] Preferably, a clamping air cylinder seat is further arranged on the first clamping air cylinder. The first clamping air cylinder is connected to the output end of the flipping motor through the clamping air cylinder seat, which can ensure a better connection between the first clamping air cylinder and the flipping motor.

[0013] Preferably, a lifting adjustment seat is further installed on the folding material adjusting seat. The lead screw passes through the lifting connector and is connected to the lifting adjustment seat. The lifting adjustment seat is arranged at the top of the lead screw, which can limit the upward movement of the lifting connector after it meets the lifting adjustment seat.

[0014] Preferably, a limiting groove is arranged on the folding material adjusting seat. The flipping motor base passes through the limiting groove and is connected to the lifting connector, ensuring that the flipping motor base only performs a lifting movement within the range defined by the limiting groove.

[0015] Preferably, a lifting motor seat is installed on the lifting motor. The lifting motor is installed on the folding material adjusting seat through the lifting motor seat. Fixing the lifting motor through the lifting motor seat can ensure the stable installation of the lifting motor.

[0016] Preferably, a lifting slide rail is further arranged on the folding material adjusting seat. A slider is arranged on the lifting slide rail. The slider is connected to the flipping motor base. The cooperation between the lifting slider and the slider can improve the smoothness of the upward or downward movement of the flipping motor base.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In the prior art, generally after the upper clip holds the sleeve fork, the folding clip is driven by a flipping motor to flip upwards for folding. The back of the sword head of the sleeve fork faces upwards. If sewn directly, it will result in the sleeve fork being sewn from the back, with neat stitches appearing behind the sleeve fork, while the stitches on the sword head of the sleeve fork that need to be shown will be relatively messy.

[0019] Therefore, in the present invention, a lifting motor drives a lifting connector to perform a lifting movement in the vertical direction. The lifting connector is connected to the flipping motor base, so that the lifting motor drives the folding component to perform a lifting movement. After the lifting motor lifts the folding component, the first clamping cylinder controls the upper clip to tilt upwards, places the sleeve fork fabric above the positioning piece, and places the sleeve fork surface to be flipped above the first lower clip. The first clamping cylinder controls the upper clip to drop and clamp the flipped sleeve fork surface. The flipping motor controls the first clamping cylinder and the clamped flipped sleeve fork surface to flip downwards together to the lower side of the second lower clip. Then the lifting motor drives the flipping motor base to descend to the workbench plane through the lifting connector, and the folding component also returns to the workbench plane. The negative pressure chamber in the suction seat generates negative pressure, which can suck the flipped sleeve fork fabric to prevent it from scattering. The second clamping cylinder controls the second lower clip to clamp the sleeve fork fabric flipped to the back to complete the folding and shaping work of the sleeve fork fabric. During the whole process, the sword head of the sleeve fork is in the state of facing upwards, and there is no need for the operator to manually turn it over. It can directly enter the pressing and sewing process for sewing, and the stitches sewn are located on the front of the sword head of the sleeve fork. The stitches of the sleeve fork are neat and the overall visual effect is good.

[0020] Therefore, the present invention provides a fabric folding and shaping mechanism for a sleeve fork machine. The sword head of the sleeve fork can be kept facing upwards during the flipping and folding process for sewing, which not only improves the working efficiency of the sleeve fork machine but also saves manpower and material resources.

After the sleeve vent fabric is folded, the drawing and moving component drives the folding material component to be drawn out from the sleeve vent fabric, and the folded sleeve vent fabric proceeds to the next process.

[0039] An intermediate separator 19 is also arranged at the bottom of the first lower clamping piece 7. The intermediate separator 19 is installed on the first clamping cylinder 3 through an intermediate separator seat 20.

The cooperation between the lifting slider 26 and the slider can improve the smoothness of the upward or downward movement of the flipping motor seat 2.

[0045] The using and working method of the present invention is as follows:

[0046] When the sleeve slit machine process starts, the lifting motor 9 starts and drives the lifting connector 11 to rise to a certain height through the lead screw. The lifting connector 11 drives the folding component to rise to a certain height. The lifting motor 9 pauses. The first clamping cylinder 3 controls the upper clamping piece 5 to tilt up, places the sleeve slit fabric above the positioning piece 6, and places the sleeve slit surface to be flipped above the first lower clamping piece 7. The first clamping cylinder 3 controls the upper clamping piece 5 to fall and clamp the flipped sleeve slit surface. The flipping motor 1 then controls the first clamping cylinder 3 and the clamped flipped sleeve slit surface to flip downward together below the first lower clamping piece 7. The lifting motor 9 then drives the flipping motor base 2 to descend to the workbench plane through the lifting connector 11, and the folding component also returns to the workbench plane. The negative pressure chamber in the suction seat 14 generates negative pressure, which can suck the flipped sleeve slit fabric to prevent it from scattering. The second clamping cylinder 4 controls the second lower clamping piece 8 to clamp the sleeve slit fabric flipped to the back, completing the folding and shaping work of the sleeve slit fabric.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0048] In the prior art, generally after the upper clamping piece 5 clamps the sleeve slit, the folding clamping piece is driven by the flipping motor 1 to flip upward for folding. The back of the sword head of the sleeve slit faces upward. If directly sewn, it will result in the sleeve slit being sewn from the back, and the neat stitches will appear behind the sleeve slit, while the stitches on the sword head of the sleeve slit that need to be shown will be relatively messy.

[0049] Therefore, in the present invention, the lifting motor 9 drives the lifting connector 11 to perform lifting and lowering movements in the vertical direction. The lifting connector 11 is connected to the flipping motor base 2, so that the lifting motor 9 drives the folding component to perform lifting and lowering movements. After the lifting motor 9 lifts the folding component, the first clamping cylinder 3 controls the upper clamping piece 5 to tilt up, places the sleeve slit fabric above the positioning piece 6, and places the sleeve slit surface to be flipped above the first lower clamping piece 7. The first clamping cylinder 3 controls the upper clamping piece 5 to fall and clamp the flipped sleeve slit surface. The flipping motor 1 controls the first clamping cylinder 3 and the clamped flipped sleeve slit surface to flip downward together below the second lower clamping piece 8. The lifting motor 9 then drives the flipping motor base 2 to descend to the workbench plane through the lifting connector 11, and the folding component also returns to the workbench plane. The negative pressure chamber in the suction seat 14 generates negative pressure, which can suck the flipped sleeve slit fabric to prevent it from scattering. The second clamping cylinder 4 controls the second lower clamping piece 8 to clamp the sleeve slit fabric flipped to the back, completing the folding and shaping work of the sleeve slit fabric. During the whole process, the sword head of the sleeve slit is in the state of facing upward, and the operator does not need to manually turn it over. It can directly enter the pressing and sewing process for sewing, and the sewn stitches are located on the front of the sword head of the sleeve slit. The stitches of the sleeve slit are neat and the overall visual effect is good.

[0050] In summary, the present invention provides a fabric folding and shaping mechanism for a sleeve placket machine. During the flipping and folding process of the sword-shaped head of the sleeve placket, sewing can be carried out with the front side facing up. This not only improves the working efficiency of the sleeve placket machine but also saves manpower and material resources.

[0051] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art of this technology, several improvements and refinements can be made without departing from the spirit and scope of the present invention, and these improvements and refinements should also be regarded as the protection scope of the present invention.
