Description

Technical Field

[0001] This utility model relates to the field of garment production and processing technology, specifically to a high-efficiency shoulder pad cutting device for suit processing. Background Technology

[0002] A suit, also known as a suit jacket, is formal attire worn on formal occasions, and is a way to show politeness and respect for the occasion. With the gradual development of society, economy, and culture, suits have become increasingly integrated into people's lives, becoming professional attire and work clothes in many fields. Shoulder pads are an essential component in the production of suits. Suit shoulder pads are semi-circular or oval-shaped padding placed under the shoulders of the garment, and are an important auxiliary material for shaping the shoulder. The function of shoulder pads is to keep the shoulders level. The correct sewing method for suit shoulder pads requires ensuring a natural fit between the shoulder and the pad. It involves fixing it with coverstitching and adjusting the ease to create a three-dimensional shoulder shape. Specific steps include positioning, trimming, coverstitching, and adjustment, paying attention to differences in the front and back positions and alignment of the armhole unsealing. Covering is a crucial step in the shoulder pad sewing process. Currently, covering shoulder pads are typically done using automatic sewing machines. After sewing, the scrap fabric needs to be trimmed. While existing automatic sewing machines have a cutter on one side of the presser foot, the cutter's fixed position limits its use. The fixed cutting position cannot meet the cutting needs of shoulder pads of different sizes. Furthermore, the fabric scraps from the cutter often fall around the presser foot, requiring manual collection before sewing the next shoulder pad to avoid affecting the sewing quality and thus impacting production efficiency. Therefore, developing a high-efficiency shoulder pad cutting device for suit processing with a reasonable structural design, adjustable cutter position, automatic waste collection, and significantly improved production efficiency is objectively necessary. Summary of the Invention

[0003] The purpose of this utility model is to provide a high-efficiency shoulder pad cutting device for suit processing with reasonable structural design, adjustable cutting blade position, automatic waste collection, and effective improvement of production efficiency.

[0004] The purpose of this utility model is achieved as follows: it includes a support frame and a sewing machine body. The bottom of the sewing machine body is provided with a presser foot and a sewing needle that cooperate with each other. A top beam is detachably mounted on the sewing machine body, and a lifting cylinder is mounted on the top beam. A translation mechanism is mounted on the lower end of the lifting cylinder, and a frame is mounted on the translation mechanism. A drive motor is mounted on the frame, and a cutter shaft is mounted on the output shaft of the drive motor. A ring cutter is mounted at the end of the cutter shaft, facing the presser foot. A sewing platform is fixedly mounted on the support frame below the presser foot. A waste material chute is provided on the side near the sewing platform. The waste material chute is detachably mounted on the support frame via a lifting adjustment frame. A waste material collection box is provided below the lower end of the waste material chute, and a material gripping mechanism is provided above the waste material chute, mounted on the frame.

[0005] Compared with existing technologies, the advantages of this device are as follows: First, this device optimizes the installation mechanism of the ring cutter. The ring cutter can move up and down using the control of the lifting cylinder mechanism, which can adjust the trimming requirements of different thickness shoulder pads in a timely manner. The ring cutter can also move left and right using the translation mechanism, adjusting the relative distance between the ring cutter and the sewing needle. This allows for adjustment of the edge trimming width after the shoulder pad is sewn, improving the ability to trim the edges of different widths after the shoulder pad is sewn, further expanding the applicability of the device and improving the ease of use of the sewing machine. Second, this device has a waste material chute on one side of the sewing platform, where the waste material trimmed and cut by the ring cutter is stored. The material-grabbing mechanism can pick up the waste material and place it into the waste material chute. The waste material chute can then automatically collect the waste material into the waste collection box. During the waste material collection process, the inclination of the waste material chute can be adjusted using a lifting and adjusting frame to facilitate the timely entry of waste material into the waste collection box, preventing waste material from accumulating in the waste material chute. This device not only improves the applicability of the device, meeting the trimming and cutting needs of shoulder pads of different thicknesses, but also solves the shortcomings of manual waste material collection, improving the convenience of waste material collection and significantly increasing production efficiency. It has the advantages of reasonable structural design, convenient and quick use, and is easy to promote and use. Attached Figure Description

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0011] like Figures 1-3 As shown, this utility model includes a support frame 1 and a sewing machine body 2. The bottom of the sewing machine body 2 is equipped with a presser foot 3 and a sewing needle 4 that cooperate with each other. The sewing machine body 2 is existing technology. The sewing machine body 2 can control the sewing needle 4 to sew shoulder pads and armholes. Then, the presser foot 3 is lowered. As the sewing needle 4 continues to sew the shoulder pads, the shoulder pads and armholes move on the sewing platform 11. A top beam 5 is detachably installed on the sewing machine body 2. The cross beam 5 can be fixed by bolt connection. A lifting cylinder 6 is installed on the top beam 5. The lifting cylinder 6 is a structure used in existing technology. The lifting cylinder 6 can be directly purchased as a finished product based on the required stroke. A translation mechanism is installed at the lower end of the lifting cylinder 6. A frame 7 is installed on the translation mechanism, and a drive motor is installed on the frame 7. 8. The drive motor 8 is a structure used in the prior art. It can be directly purchased as a finished product according to the power required. A cutter shaft 9 is installed on the output shaft of the drive motor 8. A ring cutter 10 is installed at the end of the cutter shaft 9. The ring cutter 10 faces the side of the presser foot plate 3 and is located on the rear side of the presser foot plate 2. This makes it convenient for the ring cutter 10 to cut the edge of the sewn shoulder pad. A sewing platform 11 is fixedly installed on the support frame 1 below the presser foot plate 3. A waste material chute 12 is provided on the side near the sewing platform 11. The waste material chute 12 is detachably installed on the support frame 1 via a lifting adjustment frame. A waste material collection box 13 is provided below the lower end of the waste material chute 12. A material gripping mechanism is provided above the waste material chute 12 and is installed on the frame 7.

[0012] The working process of this device is as follows: The top beam 5 is installed on the sewing machine body 2. Then, the armhole to be sewn is placed on the sewing platform 11. The shoulder pad is then attached to the armhole. The presser foot 3 is lowered to position the shoulder pad and armhole. The lifting cylinder 6 controls the overall lifting and lowering of the translation mechanism, frame 7, drive motor 8, cutter shaft 9, and circular cutter 10, adjusting the height between the circular cutter 10 and the shoulder pad to ensure precise contact. After the height adjustment, the lifting cylinder 6 stops. The translation mechanism then moves the frame 7 left and right, which in turn moves the drive motor 8, cutter shaft 9, and circular cutter 10, adjusting the distance between the circular cutter 10 and the edge of the shoulder pad to determine the required shoulder pad edge width. After the distance is adjusted, the sewing machine body 1 controls the sewing needle 2 to automatically sew the shoulder pad and armhole together. During the sewing process, the stitching... After the shoulder pad moves from the back of the presser foot 3, the drive motor 8 is turned on. The drive motor 8 drives the cutter shaft 9 to rotate, which in turn drives the annular blade 10 to rotate. The rotating annular blade 10 can trim the edge of the sewn shoulder pad, ensuring that the edge of the shoulder pad is neat. The shoulder pad edge waste cut off by the annular cutter 10 will generally fall into the waste material chute 12 automatically. If some of the cut shoulder pad waste cannot fall into the waste material chute 12 automatically, a material gripping mechanism can be used to... Waste material is collected and fed into the waste material chute 12, and then transferred to the waste material collection box 13. During the waste material collection process, the inclination of the waste material chute 12 can be adjusted using a lifting adjustment frame to ensure that the waste material entering the waste material chute 13 is promptly transferred to the waste material collection box 13, preventing waste material from accumulating in the waste material chute 12. This solves the shortcomings of manual waste material collection, improves the convenience of waste material collection, and significantly improves production efficiency. The annular cutter 10 of this device can move up and down under the control of the lifting cylinder 6, which can adjust the cutting edge requirements of different thickness shoulder pads in a timely manner. The annular cutter 10 can also move left and right using a translation mechanism to adjust the relative distance between the annular cutter 10 and the sewing needle 2. This allows for adjustment of the edge trimming width after the shoulder pad is sewn, improving the need for different width trimming widths after shoulder pad sewing, further expanding the applicability of the device and improving the ease of use of the sewing machine body 2.

[0013] Furthermore, the translation mechanism includes a top seat 14, a transmission screw 15, and a translation motor 16.

A slide 17 is mounted on the transmission screw 15, and the frame 7 is mounted on the bottom of the slide 17. In use, the translation motor 16 is turned on, and the translation motor 16 drives the transmission screw 15 to rotate. During the rotation of the transmission screw 15, the slide 17 can be moved along the transmission screw 15, thereby driving the frame 7 to move. Preferably, a guide rod 18 is mounted on the top seat 14 on the upper side of the transmission screw 15, and the slide 17 is slidably mounted on the guide rod 18. The guide rod 18 has a guiding function, which can keep the slide 17 in a straight line during the movement and prevent deviation during the movement.

[0014] Furthermore, to facilitate adjustment of the inclination angle of the waste chute, the lifting adjustment frame includes a first base plate 19, a second base plate 20, a first support column 21, and a second support column 22. The first base plate 19 and the second base plate 20 are spaced apart and connected and fixed by a tie rod. The first support column 21 is rotatably mounted on the first base plate 19. A driver connected to the first support column 21 is installed on the first base plate 19. An adjustment threaded cavity is machined along its vertical direction at the center of the upper end of the first support column 21. An adjustment screw 23 is threadedly connected to the adjustment threaded cavity. Two positioning plates 24 are spaced apart at the bottom of the higher end of the waste chute 12. An inclined tube 25 is installed between the two positioning plates 24. A sleeve 26 is slidably mounted on the inclined tube 25. The upper end of the adjustment screw 23 is rotatably mounted below the inclined tube 25. The second support column 22 is fixedly installed on the second base plate 20.

The first support column 21 and the adjusting screw 23 fix the higher end of the waste chute 12, and the second support column 22 fixes the lower end of the waste chute 12. When it is necessary to adjust the tilt angle of the waste chute 12, the driver drives the first support column 21 to rotate. Since the adjusting screw 23 is threadedly connected to the upper end of the first support column 21, the rotation of the first support column 21 can drive the adjusting screw 23 to move. The movement of the adjusting screw 23 can drive the sleeve 26 to move on the inclined tube 25, thereby raising the higher end of the waste chute 12 and thus realizing the adjustment of the tilt angle of the waste chute 12.

[0015] Preferably, the driver includes an adjusting motor 27, a driving gear 28, and a driven gear 29. The adjusting motor 27 is a structure used in the prior art, and finished products are directly purchased according to the power required. The adjusting motor 27 is mounted on the first base plate 19. The driving gear 28 is mounted on the output shaft of the adjusting motor 27. The driven gear 29 is mounted on the first support column 21 and meshes with the driving gear 28. In use, the adjusting motor 27 is turned on, which drives the driving gear 28 to rotate. The driving gear 28 drives the driven gear 29 to rotate, and the driven gear 29 drives the first support column 21 to rotate.

[0016] Preferably, a limiting rod 30 is rotatably mounted on the bottom of the lower end of the sleeve 26, and a fixing plate 31 is installed on the top of the first support column 21 near the limiting rod 30.

Both ends of the air jet pipe 34 are sealed, and multiple air nozzles 35 are installed at equal intervals on the air jet pipe 34. The outlet of the air nozzles 35 faces the lower end of the waste chute 12. A compressed air pipe is provided at the end of the air inlet pipe 33 and connected to it. Compressed air is delivered to the air inlet pipe 33 and the air jet pipe 34 through the compressed air pipe. The compressed air passes through the outlet of the air nozzles 35, and the air jet pressure of the air nozzles 35 can blow the waste into the waste collection box 13 in a timely manner.

[0018] Furthermore, the material gripping mechanism includes a first electric push rod 36 and a second electric push rod 37. The first electric push rod 36 and the second electric push rod 37 are structures used in the prior art. The bracket is procured as a finished product according to the usage requirements.

The fixed end of the second electric push rod 37 is mounted on the horizontal plate 38. A base is mounted on the movable end of the second electric push rod 37. Multiple gripping teeth 39 are mounted on the bottom surface of the base. When… When it is necessary to collect the cut waste material, the first electric push rod 36 drives the horizontal plate 38 and the second electric push rod 37 to move down. When they move down to above the sewing platform 11, the first electric push rod 36 stops working. The second electric push rod 37 drives the base and the gripping teeth 39 to move. The gripping force of the gripping teeth 39 and the drive of the second electric push rod 37 can collect the waste material into the waste material chute 12. After the waste material is collected into the waste material chute 12, the first electric push rod 36 and the second electric push rod 37 will automatically reset, waiting for the next waste material collection operation.
