Description

Technical Field

[0001] This utility model belongs to the field of automated sewing technology, specifically relating to an adjustable angle pusher mechanism for pocket sewing in a patch pocket sewing machine. Background Technology

[0002] A patch pocket sewing machine is an integrated mechanical device that automatically attaches, conveys, and sews pockets. It is mainly used in the sewing of pockets for denim clothing and children's trousers. Plain stitching and buttonhole stitching can be completed in one pass, suitable for sewing back pockets of various jeans and shirt pockets. The advent of patch pocket sewing machines has greatly reduced manpower and improved garment production efficiency. Patch pocket machines offer precise and fast patching, making them suitable for mass production.

[0003] For example, patent CN220887929U discloses an automatic bag-attaching device, including a frame, a folding section, a material-picking and sewing section, and a material-receiving section. The folding section and the material-picking and sewing section are respectively arranged on the frame, and the material-receiving section is located on the side close to the material-picking and sewing section. In this utility model, the folding section is used to fold the fabric edges to facilitate sewing the fabric into a pocket. The folding section folds the fabric edges at multiple positions, and then the material-picking and sewing section moves the folded fabric to a suitable position for sewing, thus sewing the fabric into a pocket.

[0004] However, existing patch pocket machines fold the pocket fabric inward along the shape of the pocket fabric on a pocket mold before sewing. This inward fold at the pocket opening is prone to being sewn onto the outside of the pocket opening due to operational errors and low precision in automated control, affecting the overall aesthetics of the pocket. Therefore, those skilled in the art have directly flipped the inward folded fabric at the pocket opening 45 degrees before sewing. However, this method is more suitable for thinner pocket fabrics. For denim or thicker fabrics, flipping the inward folded fabric at the pocket opening reveals a significant difference in thickness, increasing the difficulty of sewing. Furthermore, after sewing, this area will have noticeable "bumps," also affecting the pocket's appearance. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable angle pusher mechanism for pocket sewing. Through the coordinated use of a drive component and a conveying component, the angle pusher extends into the pocket to be sewn, pushes the folded fabric at the pocket opening inward, and then moves to the sewing area before withdrawing to begin sewing. This utility model has a simple structure, and the position of the angle pusher can be adjusted forward / backward, left / right, and up / down, making it suitable for pocket fabrics of different sizes and easy for mass production.

[0006] The technical solution disclosed in this utility model is as follows: An adjustable folding pusher mechanism for pocket sewing is fixed on the base plate of a patching machine. It includes a folding pusher, a fixed base, a driving component, and a transmission component. The driving component is connected to the transmission component, and the transmission component is disposed on the fixed base. The driving component drives the transmission component to slide on the fixed base. The folding pusher is fixed on the transmission component and moves in the same direction as the transmission component. The fixed base is also provided with a position adjustment structure, so that the position of the entire mechanism on the base plate is adjustable.

[0007] Preferably, the mounting base is provided with one or more first elongated grooves, and the substrate is provided with several first connecting holes. The screw passes through the first elongated groove and connects with the first connecting hole. The position of the screw in the first elongated groove is adjustable, so that the connection position between the entire mechanism and the substrate is adjustable.

[0008] Preferably, the driving component consists of a motor and a transmission shaft. One end of the transmission shaft is connected to the motor, and the other end is connected to the transmission component. The motor drives the transmission shaft to perform telescopic movements, which in turn drives the transmission component and the angled push knife to slide on the fixed base.

[0009] More preferably, the motor used is a linear motor.

[0010] More preferably, it also includes a support frame in the shape of an "L" with a circular hole at the top through which the motor passes and is fixed. The base plate of the support frame has one or more second elongated grooves, and the mounting base has several second connecting holes. Screws pass through the second elongated grooves and connect to the second connecting holes. The position of the screws in the second elongated grooves is adjustable, so that the installation position of the motor on the mounting base is adjustable.

[0011] More preferably, the transmission component consists of a support plate and a slider. The support plate is mounted on the slider, and a slide rail is provided at a corresponding position on the fixed seat. The slider is locked on the slide rail and slides along the slide rail. The end of the transmission shaft is fixed to the support plate. The motor drives the transmission shaft to perform telescopic movement, which in turn drives the support plate to move in the same direction.

[0012] More preferably, the top of the support plate is provided with an elliptical hole, through which the end of the drive shaft is fixed.

[0013] More preferably, the support plate has an outer side surface, the angle pusher is fixed on the outer side surface, and a third elongated groove is provided on the corresponding connection position on the angle pusher. The support plate has several third connection holes, and the screw passes through the third elongated groove and connects with the third connection hole. The position of the screw in the third elongated groove is adjustable, so that the connection position between the angle pusher and the support plate is adjustable.

[0014] Compared with the prior art, the present invention has the following technical advantages: (1) In order to better achieve the position adjustment of the corner pusher and to be suitable for sewing more pocket fabrics of various sizes, this utility model has made structural innovations in three aspects: ① One or more elongated grooves are provided on the fixed base, and several connectable holes are provided on the base plate. The fixed base is fixed to the base plate on the bag attaching machine by screws, that is, the screws pass through the elongated grooves and connect to the holes on the base plate. The fixed position of the screws in the elongated grooves can be changed, and the position of the fixed base on the base plate can be adjusted left and right. The corner pusher is set on the fixed base, and its left and right position can also be adjusted accordingly. ② A slide rail is provided on the fixed base, and a slider is connected to the support plate and the corner pusher is connected to the support plate. When the slider slides back and forth along the slide rail, it drives the corner pusher to slide back and forth, so as to realize the front and back position adjustment of the corner pusher. ③ In this utility model, a vertical elongated groove is provided on the angle-folding pusher. Correspondingly, a number of connecting holes are provided on the support plate. The screw passes through the elongated groove and connects with the holes on the support plate. The position of the screw in the elongated groove is adjustable, thereby realizing the up and down position adjustment of the angle-folding pusher.

[0015] (2) This utility model innovatively uses a linear motor, which directly converts electrical energy into linear motion without any intermediate conversion mechanism, such as gears, belts, or chains. This eliminates complex mechanical transmission components, making the structure simpler and more compact, and reducing the physical space required. In this utility model, the motor is connected to the fixed base by a support frame. The support frame has an elongated groove, which makes the connection position between the support frame and the fixed base adjustable. This allows the installation position of the motor to be reasonably adjusted according to the size of the area to be installed. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 2As shown, in this utility model, the mechanism is installed on the base plate 1 of the patch pocket sewing machine. Corresponding to the structure of the pocket, one is installed on each side of the base plate 1, as shown. Figure 1 , Figure 3 As shown, this utility model comprises a folding pusher 2, a fixed base 3, a driving component, and a transmission component. The driving component consists of a linear motor 4 and a transmission shaft 5. The fixed base 3 has a support frame 14 mounted vertically, which is L-shaped and has a circular hole 7 at the top. The linear motor 4 passes through the circular hole 7 and is fixed therethrough. The base plate of the support frame 14 has two parallel second elongated grooves 8. The fixed base 3 has several second connecting holes 9. Screws pass through the second elongated grooves 8 and connect to the second connecting holes 9. The position of the screws in the second elongated grooves 8 is adjustable, so that the installation position of the linear motor 4 on the fixed base 3 is adjustable.

[0019] The transmission component consists of a support plate 10 and a slider 11. The support plate 10 is mounted on the slider 11. A slide rail 12 is provided at a corresponding position on the fixed base 3. The slide rail 12 is placed parallel to the second elongated groove 8. The slider 11 is engaged with the slide rail 12 and slides along the slide rail 12. An elliptical hole 13 is provided at the top of the support plate 10. One end of the transmission shaft 5 is connected to a linear motor 4, and the other end passes through the elliptical hole 13 of the support plate 10 and is fixed thereon. The linear motor 4 drives the transmission shaft 5 to perform telescopic movements. The transmission shaft 5 drives the support plate 10 connected to it to slide back and forth on the slide rail 12, and then drives the support plate 10 to move in the same direction. The angled pusher 2 is fixed on the support plate 10, and the support plate 10 also moves the angled pusher 2 back and forth.

[0020] In this utility model, the fixing base 3 is provided with two parallel first elongated grooves 15. The first elongated grooves 15 are arranged in a perpendicular position to the slide rail 12. The base plate 1 is provided with a plurality of first connecting holes 16. The screw passes through the first elongated grooves 15 and connects to the first connecting holes 16. The position of the screw in the first elongated grooves 15 is adjustable. Therefore, the connection position between the entire mechanism and the base plate 1 is adjustable, so that the angle pusher 2 can be adjusted in the left and right positions.

[0021] Meanwhile, the support plate 10 also has an outer side surface, and the angle pusher 2 is fixed on the outer side surface. The angle pusher 2 has a third elongated groove 17 at the corresponding connection position. The support plate 10 has several third connection holes 18. The screw passes through the third elongated groove 17 and connects with the third connection hole 18. The position of the screw in the third elongated groove 17 is adjustable. The connection position between the angle pusher 2 and the support plate 10 is adjustable, so that the angle pusher 2 can be adjusted in the up and down position.

[0022] In practical applications, the mechanism disclosed in this utility model is installed on the base plate 1 of the patch sewing machine, with one on each side. The operator first selects the appropriate folding pusher 2 for the size of the pocket fabric folding edge according to the shape and size of the pocket fabric, and installs it on the support plate 10. At the same time, the position of the folding pusher 2 in the front-back and up-down directions is adjusted according to the position of the pocket mold. After the patch pocket sewing machine is started, the central control module controls the patch module to fold the pocket fabric and then remove it. Then, it controls the pressure block module to press the pocket fabric onto the garment to be sewn. At this time, the central control module controls the linear motor 4 to drive the transmission shaft 5 to extend forward, driving the corner pusher 2 forward and into the bottom of the pocket mold. It pushes the inner folded edge fabric at the pocket opening to the set position and then removes the patch module. At this time, the central control module controls the entire base plate to move to the sewing area and then controls the linear motor 4 to drive the transmission shaft 5 to retract backward, driving the corner pusher 2 to extend out of the pocket fabric. At this time, the inner folded edge fabric at the pocket opening is pushed a certain distance into the pocket (without any protrusions) and will not protrude out of the pocket. Sewing can then begin immediately.
