Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, and specifically relates to a buttonholing machine for clothing processing. Background Technique

[0002] Clothing processing refers to the process of making clothing from clothing materials through a series of technological processes such as cutting, sewing, and ironing. This process can be divided into three methods: light processing, processing with provided materials and auxiliary materials, and full distribution processing. Light processing means that both the fabric and auxiliary materials are provided by the processing party, and only the processing fee is agreed upon between the two parties; processing with provided materials and auxiliary materials means that the fabric is provided by the processing party, and the auxiliary materials are provided by the processing factory, including the processing fee; full distribution processing means that both the fabric and auxiliary materials are the responsibility of the processing factory. Clothing processing not only involves the design and manufacture of clothing, but also includes quality control of clothing, inspection of finished products, and final packaging and transportation.

[0003] For certain specific clothing, buttonholes need to be made on the fabric, such as shirts. After retrieval, the Chinese patent application number: CN201911179448.3 discloses a buttonholing machine for clothing processing, including a workbench, a pulling component, a punching component, and a total driving component; there is a punching hole on the workbench, and the clothing material is laid on the workbench; the pulling component is arranged on the workbench, pressing the clothing material on the workbench and capable of pulling the material to advance at intervals along the width direction of the workbench; the punching component is arranged on the workbench, and the punching knife of the punching component is aligned with the punching hole, and the punching knife punches the clothing material during the interval when the pulling component toggles the clothing material; the total driving component includes a rotating motor, a pulling transmission wheel, and a punching transmission wheel, and the total driving component can drive the punching knife to punch the clothing material during the interval when the pulling component pulls the clothing material. This buttonholing machine for clothing processing can make the clothes move smoothly during the punching process, and then punch accurately, improving the quality of buttonhole processing.

[0004] The above technical solution still has defects. After punching buttonholes in the clothing fabric, since sewing has not been carried out yet, the buttonhole part is prone to phenomena such as fraying and burrs, making the knitted or woven fabric prone to problems such as thread shedding and pilling, reducing the quality of the final product. Therefore, we need to propose a buttonholing machine for clothing processing. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-2 , the present utility model provides a technical solution:

[0030] A buttonhole-making machine for clothing processing, comprising:

[0031] Base 1; a processing table 3 for making buttonholes on garment fabrics is provided on the base 1. Rounded slopes are provided at both ends of the processing table 3. A side plate 2 is provided on one side of the base 1 where the processing table 3 is located. A lifting plate 5 is provided on one side of the side plate 2 in a liftable manner;

[0032] An opening mechanism provided on the lifting plate 5; the opening mechanism includes an ultrasonic transducer 6 and a cutting knife 7. The ultrasonic transducer 6 is installed on the lifting plate 5. The cutting knife 7 is installed at the output end of the ultrasonic transducer 6 and the cutting knife 7 is located at the bottom of the lifting plate 5. A knife groove 8 corresponding to the cutting knife 7 is provided on the processing table 3. Support plates 4 are symmetrically provided at the upper end of the side plate 2. The support plates 4 are in an inverted L shape. Two sets of cylinders 19 are installed on the two sets of support plates 4. The lower ends of the piston rods of the two sets of cylinders 19 penetrate through the support plates 4 and are fixedly connected to the surface of the lifting plate 5. The two sets of cylinders 19 are arranged synchronously.

[0033] By providing a processing table 3 with a knife groove 8 on the base 1, a side plate 2 is provided on one side of the processing table 3, support plates 4 are provided at the upper end of the side plate 2, the cylinders 19 on the support plates 4 drive the lifting plate 5 to lift and lower, and an ultrasonic transducer 6 with a cutting knife 7 is installed on the lifting plate 5. The cutting knife 7 corresponds to the knife groove 8. During actual use, the fabric to be processed is placed on the processing table 3, and one side of the fabric is attached to the side plate 2. After placement, the cylinder 19 is started to drive the lifting plate 5 to descend. The ultrasonic transducer 6 works and outputs through the cutting knife 7. The cutting knife 7 contacts the fabric to form a buttonhole. The cutting surface forms smooth, neat and durable edges, and it will not cause the textile to change color. It can also cut and sew the edge at the same time, which prevents the knitted or woven material from forming loose threads. At the same time, the sewn edge has a taper, which can avoid pilling, thus solving the problems proposed in the background technology.

[0034] Generally speaking, the structure of this device is simple and easy to use. The buttonholes are made on the fabric by ultrasonic cutting. While cutting the buttonholes, there is a fusing effect at the cutting part, and the cutting part is perfectly sealed, which can prevent the cut fabric from having a phenomenon of flying edges, ensuring that the final product has good quality.

[0035] Among them, the opening mechanism in this application specifically includes an ultrasonic transducer 6, a horn, a cutting tool 7 (tool head), and a driving power supply. The ultrasonic driving power supply converts the commercial power into a high-frequency and high-voltage alternating current and supplies it to the ultrasonic transducer 6. The ultrasonic transducer 6 is actually an energy conversion device that can convert the input electrical energy into mechanical energy, that is, ultrasonic waves. Its manifestation is that the transducer makes a reciprocating telescopic motion longitudinally. The frequency of the telescopic motion is the same as the frequency of the high-frequency alternating current supplied by the driving power supply. The horn has two functions. One is to fix the entire ultrasonic vibration system, and the other is to amplify the output amplitude of the transducer. The cutting tool 7 (tool head) further amplifies the amplitude on the one hand and focuses the ultrasonic waves on the other hand. On the other hand, it outputs ultrasonic waves and uses the similar cutting edge of the cutting tool 7 to concentrate the ultrasonic energy input into the cutting part of the material to be cut. Under the action of the huge ultrasonic energy, this part is instantly softened, melted, and the strength is greatly reduced. At this time, as long as a very small cutting force is applied, the purpose of cutting the material can be achieved.

[0036] It is worth mentioning that, please refer to Figure 2-3 :

[0037] It includes two groups of positioning mechanisms arranged on both sides of the lifting plate 5;

[0038] The positioning mechanism includes a first connecting rod 11 slidably inserted into the lifting plate 5, a fixed seat 9, and a rubber roller 10. Two groups of the first connecting rod 11 are symmetrically arranged at both ends of the lifting plate 5. The upper end of the first connecting rod 11 penetrates through the lifting plate 5 and is connected with a limit block, and a first compression spring 14 is sleeved on the first connecting rod 11. First sliding grooves 12 are symmetrically opened on both sides of the lifting plate 5, and the first connecting rod 11 is slidably inserted into the interior of the first sliding groove 12. Two rubber gaskets 13 are sleeved between the fixed seat 9 and the lifting plate 5 on the first connecting rod 11, and the first compression spring 14 is located between the two gaskets 13.

[0039] By slidably inserting the first connecting rod 11 into the lifting plate 5, sleeving the gasket 13 and the first compression spring 14 on the first connecting rod 11, and arranging the fixed seat 9 with the rubber roller 10 at the lower end of the first connecting rod 11, when the cylinder 19 drives the lifting plate 5 to descend for buttonholing, the rubber roller 10 first contacts the fabric on the processing table 3, and with the cooperation of the first connecting rod 11 and the first compression spring 14, it plays a good positioning function. Then, the cutting tool 7 contacts the fabric for buttonholing, which can position and fix the fabric before buttonholing, avoid the displacement and deflection of the fabric during the cutting process, and ensure the accuracy of the equipment for buttonholing.

[0040] Furthermore, please refer to Figure 3-4 :

[0041] A second connecting rod 15 is arranged between the inner walls on both sides of the first sliding groove 12. An arc-shaped push plate 16 is slidably sleeved on the second connecting rod 15, and a second compression spring 17 is sleeved on the second connecting rod 15 on one side of the arc-shaped push plate 16. A second sliding groove 18 is formed in the first connecting rod 11, and the second connecting rod 15 is slidably inserted into the inside of the second sliding groove 18, and the arc surface of the arc-shaped push plate 16 abuts against the outer wall of the first connecting rod 11. The height of the rubber roller 10 is 0.5 - 1 cm lower than the lower end of the cutting tool 7, and the lower end of the rubber roller 10 faces the slope of the processing table 3.

[0042] By arranging the second connecting rod 15 in the first sliding groove 12, sleeving the arc-shaped push plate 16 and the second compression spring 17 on the second connecting rod 15, slidingly inserting the second connecting rod 15 into the second sliding groove 18 on the first connecting rod 11, and making the arc-shaped push plate 16 abut against the outer wall of the first connecting rod 11, before buttonholing, the rubber roller 10 first contacts the fabric on the processing table 3. Since the rubber roller 10 is directly above the inclined plane and with the cooperation of the second connecting rod 15, the second sliding groove 18 and the second compression spring 17, the rubber roller 10 rolls along the slope while pressing down. In this process, not only can the fabric be pressed and positioned, but also a tensioning effect can be achieved, avoiding wrinkles on the fabric and further improving the quality of the equipment for buttonholing.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
