Description

Technical Field

[0001] This application belongs to the field of garment processing technology, specifically relating to a thread end receiving box for a sewing machine. Background Technology

[0002] The buttonhole machine is a specialized automated sewing equipment used in the garment and home textile industries. It can process round or oval buttonholes on fabrics and simultaneously reinforce the edges of the buttonholes with overlock to prevent fabric fraying and unraveling, while ensuring that the buttonholes are aesthetically pleasing and durable. During use, excess thread ends need to be trimmed to prevent them from getting tangled in the needle and to ensure the smooth operation of subsequent work.

[0003] Existing thread ends are typically collected after being cut, usually using a fan and a collection cylinder. The fan draws the thread ends into the collection cylinder, where they are then filtered through a screen. However, during use, some of the collected thread ends accumulate on the filter, clogging the mesh and affecting its breathability. Regular cleaning is required, necessitating the shutdown of the fan and taking approximately half an hour per cleaning cycle. This regular shutdown and maintenance impacts overall processing efficiency. In industrial workshops, multiple sewing machines typically operate simultaneously, requiring multiple fans to meet the demands and increasing purchase costs. Furthermore, the fans must remain running continuously during sewing machine operation, increasing energy consumption and further raising processing costs. Utility Model Content

[0004] This application provides a wire end receiving box for a sewing machine, which aims to solve the technical problem in the prior art where the use of a fan to collect wire ends requires regular cleaning of the filter screen, which increases processing costs and affects the working efficiency of the sewing machine.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A wire end receiving box for a sewing machine is provided, comprising: The main body of the storage unit has an inlet and an outlet at its top and bottom ends, respectively. The main body of the storage unit is slidably disposed at the bottom of the worktable of the eyelet machine, and the horizontal cross-sectional area of ​​the inner cavity of the main body of the storage unit gradually decreases from top to bottom. Flip the cover plate and rotate it to cover the feed inlet; and A receiving bag is placed over the discharge port to collect thread ends that fall from the receiving body.

[0006] In one possible implementation, the wire end receiving box of the eyelet sewing machine further includes two vertically arranged mounting plates, which are installed at intervals on the bottom of the eyelet sewing machine's workbench, and the two sides of the receiving body are respectively slidably attached to the corresponding mounting plates.

[0007] In one possible implementation, a sliding plate is connected to the bottom of the mounting plate, the surface of the sliding plate being perpendicular to the surface of the mounting plate, and the bottom sides of the storage body slidingly engage with the corresponding sliding plates.

[0008] In one possible implementation, pulleys are rotatably provided on both sides of the storage body, and the pulleys are in rolling cooperation with the corresponding sliding plates.

[0009] In one possible implementation, the storage body includes a first side plate, a second side plate, a third side plate, a fourth side plate, and a feed plate; the first side plate, the second side plate, the third side plate, and the fourth side plate are connected sequentially and enclose to form a rectangular structure, and the top of the first side plate, the second side plate, the third side plate, and the fourth side plate enclose to form the feed inlet; The surface of the feeding plate gradually slopes away from the first side plate from top to bottom. The feeding plate is connected to the first side plate, the second side plate and the fourth side plate respectively, and cooperates with the third side plate to form the discharge port.

[0010] In one possible implementation, the opening of the receiving bag and the bottom opening of the storage body are connected by a connector.

[0011] In one possible implementation, the connector includes: A connecting ring is fixed to the outside of the discharge port, and the upper surface of the connecting ring is provided with a connecting protrusion; The fixing ring has a fixing groove at the bottom, which is inserted and fixed to the connecting protrusion to clamp the opening of the receiving bag.

[0012] In one possible implementation, the flip cover includes a cover body and a rotating shaft, with the two ends of the rotating shaft connected to the second side plate and the fourth side plate, respectively, and the middle part of the cover body rotatably sleeved on the outer periphery of the rotating shaft.

[0013] In one possible implementation, a handle is mounted on the outer side of the first side plate.

[0014] In one possible implementation, the receiving bag has a pull rope at its opening for lifting the receiving bag.

[0015] The eyelet sewing machine provided in this application has a wire end receiving box. Compared with the prior art, when the eyelet sewing machine is working, the wire ends produced are manually opened by the operator using a flip-top cover. The wire ends are placed into the receiving body, and they fall downwards under gravity. Because the horizontal cross-sectional area of ​​the inner cavity of the receiving body gradually decreases from top to bottom, forming a guide structure that is wider at the top and narrower at the bottom, the wire ends will slide naturally along the inner cavity wall and finally fall into the covered receiving bag from the bottom outlet for collection. When a certain amount of wire ends are collected in the receiving bag, the receiving bag can be directly removed for cleaning or replacement without the need for complex disassembly of the receiving body. This receiving box requires no fan or filter; it collects threads directly from the receiving bag via gravity guidance, eliminating the problem of thread buildup and filter clogging. Therefore, regular filter cleaning and maintenance are unnecessary, shortening the processing cycle and improving overall efficiency. The receiving box and receiving bag are cost-effective; each box can be hung one-to-one on the bottom of the workbench of each eyelet machine, eliminating the need for an additional fan and significantly reducing equipment purchase costs. Furthermore, unlike a fan, it doesn't need to be constantly running, reducing energy expenditure during processing. The flip-up cover automatically closes when no threads are flowing, blocking the feed inlet and preventing threads from escaping from the receiving box, ensuring all threads are collected within the receiving box and receiving bag. The receiving bag cover is located at the discharge port, allowing for convenient replacement after a certain amount of threads have been collected, simplifying the replacement process.

[0025] Please refer to the following: Figures 1 to 6 The present application describes the thread-hanging receiving box for the eyelet sewing machine. The thread-hanging receiving box includes a main body 1, a flip-top cover 2, and a receiving bag 3. The main body 1 has an inlet 101 and an outlet 102 at its upper and lower ends, respectively. The main body 1 is slidably disposed at the bottom of the worktable 61 of the eyelet sewing machine 6, and the horizontal cross-sectional area of ​​the inner cavity of the main body 1 gradually decreases from top to bottom. The flip-top cover 2 is rotated and placed over the inlet 101. The receiving bag 3 is placed over the outlet 102 and is used to collect thread ends falling from the main body 1.

[0026] The working process of this embodiment is as follows: When the eyelet machine is working, the thread ends produced by cutting are manually opened by the employee using the flip cover 2, and the thread ends are placed into the collection body 1. The thread ends fall downwards under the action of gravity. Since the horizontal cross-sectional area of ​​the inner cavity of the collection body 1 gradually decreases from top to bottom, forming a guide structure that is wider at the top and narrower at the bottom, the thread ends will slide down naturally along the inner cavity wall and finally fall into the covered receiving bag 3 from the discharge port 102 at the bottom for collection. When a certain amount of thread ends are collected in the receiving bag 3, the receiving bag 3 can be directly removed for cleaning or replacement without the need for complicated disassembly of the collection body 1.

[0027] It should be noted that the receiving bag 3 can be a regular plastic bag. Plastic bags are low in cost, widely available, and can hold a certain amount of thread ends to meet usage needs.

[0028] The thread collection box provided in this embodiment for the eyelet machine eliminates the need for a fan and filter. It collects threads directly from the receiving bag 3 via gravity guidance, preventing thread accumulation and filter clogging. This eliminates the need for regular filter cleaning and maintenance, shortening the processing cycle and improving overall efficiency. The collection body 1 and receiving bag 3 are cost-effective. Each collection box can be hung one-to-one on the bottom of the workbench of each eyelet machine, eliminating the need for an additional fan and significantly reducing equipment purchase costs. Furthermore, unlike a fan, it doesn't need to be constantly running, reducing energy expenditure during processing. The flip-top cover 2 automatically closes when no threads are flowing, blocking the feed inlet 101 and preventing threads from escaping from the collection body 1, ensuring all threads are collected within the collection body 1 and receiving bag 3. The design of the receiving bag 3 covering the discharge port 102 allows for easy replacement after a certain amount of threads have been collected, reducing the difficulty of replacement.

[0029] In some embodiments, see Figure 1 and Figure 3 The wire end receiving box for the eyelet sewing machine also includes two vertically arranged mounting plates 4. The two mounting plates 4 are spaced apart and installed at the bottom of the worktable 61 of the eyelet sewing machine 6. The two sides of the storage body 1 slide and adhere to the corresponding mounting plates 4. The sliding and adhering fit between the two sides of the storage body 1 and the mounting plates 4 ensures that the storage body 1 moves in a fixed direction when pulled out and adjusted, avoiding deviation and shaking, and improving collection accuracy. The spaced arrangement of the mounting plates 4 provides lateral restraint for the storage body 1, enhancing the overall structural stability. At the same time, the presence of the mounting plates 4 simplifies the installation process of the storage body 1, eliminating the need for complex fixing structure design at the bottom of the worktable, reducing installation difficulty, and facilitating the disassembly and maintenance of the storage body 1 later.

[0030] In some embodiments, see Figure 3 A sliding plate 41 is connected to the bottom of the mounting plate 4. The surface of the sliding plate 41 is perpendicular to the surface of the mounting plate 4. The bottom sides of the storage body 1 slide in cooperation with the corresponding sliding plates 41. The sliding plates 41 are perpendicularly connected to the mounting plate 4, forming an "L"-shaped support structure that supports the storage body 1 from the bottom. The sliding cooperation between the bottom sides of the storage body 1 and the sliding plates 41 ensures that the pulling action of the storage body 1 is simultaneously guided by the side mounting plate 4 and supported by the bottom sliding plate 41. This makes the sliding process smoother and more stable, reduces jamming, lowers the operating resistance when adjusting or maintaining the device, and improves ease of use.

[0031] In some embodiments, see Figure 1 and Figure 2The storage body 1 has rotatable pulleys 16 on both sides, which roll in cooperation with the corresponding sliding plates 41. The pulleys 16 convert the sliding friction between the storage body 1 and the sliding plates 41 into rolling friction, greatly reducing the frictional resistance between them and making it easier for the operator to pull out the storage body 1. Rolling friction causes less wear on the parts than sliding friction, which can extend the service life of the storage body 1 and the sliding plates 41 and reduce the cost of replacing parts later. In addition, the rolling cooperation of the pulleys 16 is more stable, which can further prevent the storage body 1 from deviating or jamming when it is pulled out, ensuring smooth operation.

[0032] In some embodiments, see Figures 1 to 3 The main body 1 includes a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, and a feed plate 15. The first side plate 11, the second side plate 12, the third side plate 13, and the fourth side plate 14 are connected in sequence and enclose to form a rectangular structure. The top of the first side plate 11, the second side plate 12, the third side plate 13, and the fourth side plate 14 enclose to form a feed inlet 101. The surface of the feed plate 15 gradually slopes away from the first side plate 11 from top to bottom. The feed plate 15 is connected to the first side plate 11, the second side plate 12, and the fourth side plate 14 respectively, and cooperates with the third side plate 13 to form a discharge outlet 102.

[0033] The storage body 1 provided in this embodiment has a simple structure. The rectangular side panel enclosure design gives the inlet 101 a large opening area, which can more comprehensively receive the thread ends falling from the eyelet machine, improve the collection coverage, and keep the workshop clean. The inclined discharge plate 15 can guide the thread ends to slide down quickly, avoiding the accumulation of thread ends inside the storage body 1, ensuring that the thread ends flow smoothly to the discharge port 102, improving collection efficiency. The discharge port 102 formed by the discharge plate 15 and the third side plate 13 is more concentrated and can be accurately aligned with the opening of the receiving bag 3, further reducing the leakage of thread ends and ensuring the collection effect.

[0034] In some embodiments, see Figure 4 The opening of the receiving bag 3 and the bottom opening of the storage body 1 are connected by a connector 5. The connector 5 makes the connection between the receiving bag 3 and the bottom opening of the storage body 1 more secure, avoiding gaps that may occur if only a cover is used, preventing thread ends from leaking out from the connection point, and ensuring the airtightness of the collection. When the receiving bag 3 is full of thread ends, the operator can easily remove the receiving bag 3 through the connector 5 for cleaning. It can also be quickly fixed when replacing with a new receiving bag 3. The whole process does not require complicated tools, is simple and efficient, and will not damage the receiving bag 3 or the storage body 1 due to improper disassembly, thus extending the service life of the components.

[0035] In some embodiments, see Figure 4The connector 5 includes a connecting ring 51 and a fixing ring 52. The connecting ring 51 is fixed to the outside of the discharge port 102, and a connecting protrusion 511 is provided on the upper surface of the connecting ring 51. The fixing ring 52 has a fixing groove 521 at the bottom, which is inserted into the connecting protrusion 511 to clamp the opening of the receiving bag 3. The plug-in connection structure does not require any tools. The operator only needs to align the fixing groove 521 of the fixing ring 52 with the connecting protrusion 511 of the connecting ring 51 and insert it to complete the fixation, while clamping the opening of the receiving bag 3. The installation and disassembly process is quick and convenient, which greatly shortens the replacement time of the receiving bag 3 and further reduces interference with the working process of the eyelet machine. The clamping fixing method can tightly fit the opening of the receiving bag 3, which not only prevents the thread end from leaking out, but also avoids the receiving bag 3 from tearing due to excessive force, thus extending the service life of the receiving bag 3. Moreover, the connector 5 has a simple structure, low manufacturing cost, and is easy to mass-produce.

[0036] As another embodiment of the connector 5, the connector 5 includes double-sided adhesive, the two sides of which are respectively bonded to the side of the discharge port 102 and the opening side of the receiving bag 3, so that the receiving bag 3 and the discharge port 102 are bonded and sealed.

[0037] In some embodiments, see Figure 1 , Figure 2 as well as Figure 6 The flip cover 2 includes a cover body 21 and a rotating shaft 22. The two ends of the rotating shaft 22 are respectively connected to the second side plate 12 and the fourth side plate 14. The middle part of the cover body 21 is rotatably sleeved on the outer periphery of the rotating shaft 22.

[0038] It should be noted that, for reference Figure 3 The cover plate body 21 and the worktable 61 are spaced apart in the vertical direction, which makes it convenient for employees to push the cover plate body 21 to rotate around the rotation axis 22. Due to the existence of the space, the cover plate body 21 can rotate freely, and the worktable 61 will not hinder the rotation of the cover plate body 21.

[0039] It should be noted that the main storage unit 1 can slide directly under the workbench 61. If only half of the main storage unit 1 needs to be exposed, a cover plate 2 that only covers the exposed part can be installed as needed. (See reference...) Figure 1 and Figure 2 Alternatively, a cover plate body 21 can be installed to completely cover the feed inlet 101, see reference. Figure 6 .

[0040] In this embodiment, the rotating shaft 22 is connected to the second side plate 12 and the fourth side plate 14 at both ends, making the installation of the flip cover 2 more stable and preventing the cover body 21 from loosening or falling off during use. The middle part of the cover body 21 is sleeved on the outer periphery of the rotating shaft 22, and can rotate flexibly around the rotating shaft 22. When the wire ends fall, only an impact force is needed from the employee to push the cover body 21 open, without obstructing the falling wire ends and ensuring smooth collection. At the same time, when there are no falling wire ends, the cover body 21 can automatically reset around the rotating shaft 22 under its own gravity, closing the feed port 101. There is no need for the operator to manually close the cover, saving labor costs and improving ease of use.

[0041] In some embodiments, see Figure 2 A handle 17 is installed on the outer side of the first side plate 11. The handle 17 provides the operator with a clear point of force application. When it is necessary to pull out and store the main body 1, the operator can directly hold the handle 17 to operate, making the pulling action more effortless and stable.

[0042] In some embodiments, see Figure 5 The receiving bag 3 has a lifting rope 31 at its opening, which is used to lift the receiving bag 3. The lifting rope 31 makes it convenient for operators to lift the receiving bag 3. When the receiving bag 3 is full of thread ends, the operator can easily lift the receiving bag 3 through the lifting rope 31, ensuring hygiene and convenience in operation.

[0043] It should be noted that the lifting rope 31 is a thin line and does not affect the normal use of the connector 5.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
