Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and more specifically, to a thread collection device and a sewing machine. Background Technology

[0002] In the field of sewing machine thread handling, the thread collection device is a key component to ensure smooth sewing operations and stable equipment operation. However, existing thread collection devices have some obvious limitations, especially in the design of the thread collecting plate and the thread suction component.

[0003] In existing technologies, the thread collecting plate and the thread suction device are separate structures. While this can achieve the function of collecting thread ends to a certain extent, in actual use, because the thread collecting plate and the thread suction device are separate, their fit is not tight enough, causing thread ends to easily scatter during collection. This not only reduces the efficiency of thread end cleaning but also allows thread ends to accumulate inside the sewing machine, causing problems such as equipment jamming and decreased sewing accuracy. Moreover, most existing thread end collection devices simply collect thread ends. During the thread cutting process, the thread ends are not effectively fixed and guided, resulting in unstable cutting quality and uneven thread lengths.

[0004] Therefore, how to solve the problems of unstable wire cutting quality and low wire cleaning efficiency of existing wire end collection devices is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a thread end collection device that can effectively fix and guide the thread ends during the cutting process, so that the cut thread ends are of uniform and neat length. At the same time as cutting the thread, the thread ends are sucked into the suction device and discharged, thereby improving the efficiency of thread end cleaning.

[0006] Another objective of this invention is to provide a sewing machine that includes the aforementioned thread collection device, thereby improving overall work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wire end collection device includes: a wire suction component, which has a suction channel that runs through it, a boss for fixing itself on the outside of the wire suction component, a wire suction structure for sucking up the wire end at the wire cut notch at one end of the wire suction component, and a wire suction tube connected to an external vacuum generator at the other end of the wire suction component. The wire suction component is an integral structure.

[0009] Preferably, the suction structure is configured as an annular groove communicating with the suction channel, the annular groove corresponding to the wire cutting notch, and the other end of the suction component has a chamfered structure that connects to the suction tube.

[0010] Preferably, the boss is connected to the housing via a connecting bracket, and the connecting bracket is provided with an adjustment elongated hole for adjusting the installation position of the boss.

[0011] Preferably, the boss has at least two mounting holes, and the mounting holes are equipped with connecting screws. The connecting screws connect the boss and the connecting bracket through a fixing plate.

[0012] Preferably, the connecting bracket includes two horizontally arranged horizontal plates and one vertically arranged vertical plate, the vertical plate being perpendicular to the horizontal plates and used to connect the two horizontal plates.

[0013] Preferably, the housing is provided with a cutting assembly, which is located below the wire cutting notch.

[0014] Preferably, the cutter assembly includes a cutter holder assembly and a cutter. The cutter holder assembly is disposed on the machine housing, and the cutter is vertically disposed on the cutter holder assembly with the cutting edge facing the wire cutting notch.

[0015] Preferably, the wire suction structure is located on one side of the cutter.

[0016] A sewing machine includes a housing, on which a thread collection device as described in any of the preceding claims is provided.

[0017] Preferably, it also includes a tabletop located on the housing, the tabletop having a wire-cutting notch and a scissor assembly, the scissor assembly being located on one side of the wire-cutting notch.

[0018] The thread-collecting device provided by this utility model includes a thread-suction component. Specifically, the thread-suction component has a suction channel that runs through it, allowing the suction force to act directly on the thread end at the cutting notch, ensuring efficient transmission of suction force and allowing the thread end to be quickly sucked into the channel. By setting up the suction channel, the suction force is more concentrated and stable, enabling more thorough cleaning of thread ends and keeping the sewing machine's interior clean. The thread-suction component has a boss on its exterior for fixing itself, making the installation of the thread-suction component more stable and reliable. One end of the thread-suction component has a suction structure for sucking up the thread end at the cutting notch, straightening the thread end before cutting, ensuring that the scissors can accurately cut from the root of the thread end, improving the cutting quality, and making the cut thread ends uniform and neat. The other end of the thread-suction component is connected to a suction tube of an external vacuum generator, so that the suction tube can provide a stable and strong negative pressure suction force to the thread-suction component, ensuring that the thread end can be quickly and effectively sucked into the suction channel of the thread-suction component. The wire suction device is an integrated structure that combines wire collection and wire cutting into one unit, enabling the wire cutting and cleaning to be completed simultaneously. While cutting the wire, the wire end is sucked into the suction channel and discharged and collected with the suction tube, which improves the wire cutting quality and wire cleaning efficiency of the wire collection device.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] It should be noted that the directional terms such as "down" in the following text are based on the definitions in the accompanying drawings of the instruction manual.

[0040] The core of this invention is to provide a thread end collecting device that effectively fixes and guides the thread ends during the cutting process, ensuring that the cut thread ends are of uniform and neat length. Simultaneously, the thread ends are sucked into the suction device 1 and discharged, improving thread end cleaning efficiency. Another core aspect of this invention is to provide a sewing machine incorporating the aforementioned thread end collecting device, thereby improving overall work efficiency.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 A thread collection device includes a thread suction element 1.

[0042] Specifically, the thread suction unit 1 has a suction channel running through it, allowing the suction force to directly act on the thread end at the thread cutting notch 9, ensuring efficient transmission of suction force and allowing the thread end to be quickly sucked into the channel. By setting up the suction channel, the suction force is more concentrated and stable, enabling more thorough cleaning of the thread end and keeping the sewing machine's interior clean. The thread suction unit 1 has a boss 11 on its exterior for fixing itself, making the installation of the thread suction unit 1 more stable and reliable. One end of the thread suction unit 1 has a thread suction structure 12 for sucking up the thread end at the thread cutting notch 9, straightening the thread end before cutting, ensuring that the scissors can accurately cut from the root of the thread end, improving the quality of thread cutting, and making the cut thread end uniform and neat. The other end of the thread suction unit 1 is connected to the suction tube 2 of an external vacuum generator, so that the suction tube 2 can provide a stable and strong negative pressure suction force to the thread suction unit 1, ensuring that the thread end can be quickly and effectively sucked into the suction channel of the thread suction unit 1. The suction device 1 is an integrated structure that combines the wire end collection and wire cutting actions into one, so as to achieve the simultaneous completion of wire end cutting and cleaning. While cutting the wire, the wire end is sucked into the suction channel and discharged and collected with the suction pipe 2, which improves the wire cutting quality and wire end cleaning efficiency of the wire end collection device.

[0043] The thread collection device designed in the above manner, through the integrated thread suction component 1, can improve the quality of thread cutting and increase the efficiency of thread cleaning, effectively meeting the requirements of modern sewing production for high quality, high efficiency and high stability.

[0044] In the above embodiment, the suction structure 12 is configured as an annular groove communicating with the suction channel, the annular groove corresponding to the wire cutting notch 9, and the other end of the suction component 1 is provided with a chamfered structure 13 connected to the suction tube 2.

[0045] It should be noted that the chamfered structure 13 is used to connect the suction tube 2, making the connection between the suction tube 2 and the suction component 1 smoother, reducing airflow resistance at the connection point, and ensuring that the suction force can be efficiently transferred to the annular groove, improving the suction speed and collection efficiency of the thread end. Simultaneously, the chamfered structure 13 also helps reduce thread bounce or scattering caused by airflow impact, further improving the stability of thread end collection. The annular groove is used to collect thread ends. The annular groove corresponds to the thread cutting notch 9, allowing the suction structure 12 to accurately align with the thread end generated at the thread cutting notch 9, ensuring that the thread end is quickly sucked into the annular groove the moment it is generated, avoiding the scattering and accumulation of thread ends inside the sewing machine, and improving the efficiency and thoroughness of thread end collection. The design of the annular groove allows the suction force to be evenly distributed around the thread cutting notch 9, forming an all-around suction field, which can more effectively suck in and fix the thread end in the annular groove, reducing the problem of thread end residue or loosening caused by uneven suction force, further improving the thread end collection effect.

[0046] Furthermore, the design of the annular groove straightens and fixes the thread end in a specific position, ensuring the thread end is stable before cutting. This guarantees that the scissors can accurately cut from the root of the thread, avoiding uneven or incomplete cuts caused by loose thread ends, significantly improving the quality and precision of thread cutting. The corresponding design of the annular groove and the thread cutting notch 9 allows the thread suction structure 12 and the thread cutting action to work in perfect coordination. Before cutting, the annular groove straightens and fixes the thread end; during cutting, the thread end is stable, ensuring accurate cutting by the scissors; after cutting, the thread end is sucked into the suction channel along the annular groove and discharged for collection. This coordinated working method makes the thread cutting and thread end collection process more orderly and efficient, reducing sewing defects caused by thread end problems and improving the operating efficiency and stability of the sewing machine.

[0047] The design of connecting the annular groove with the suction channel and the chamfered structure 13 make the entire suction component 1 more compact and integrated, reducing the size and weight of the device, saving valuable space inside the sewing machine, and allowing it to be more flexibly adapted to different models and specifications of sewing machines, thus improving the device's versatility and adaptability. The chamfered structure 13 makes the connection between the suction tube 2 and the suction component 1 simpler and faster, saving time and effort, improving equipment maintenance efficiency, and reducing production downtime caused by equipment repairs.

[0048] Please refer to Figure 4 , Figure 5 and Figure 6 The boss 11 is connected to the housing 4 via a connecting bracket 3. The connecting bracket 3 is provided with an adjustment elongated hole 31 for adjusting the installation position of the boss 11.

[0049] Understandably, the adjustable elongated hole 31 on the connecting bracket 3 allows the mounting position of the boss 11 to be flexibly adjusted according to different sewing needs. Especially when sewing products with different buttonhole lengths, the thread suction component 1 can adjust its position through the adjustable elongated hole 31 on the connecting bracket 3, ensuring that the thread suction structure 12 can accurately follow the scissor assembly 10, thereby improving the efficiency and quality of thread collection. This flexibility allows the thread collection device to better adapt to diverse sewing tasks and meet the needs of different users.

[0050] Furthermore, different sewing machines may have different internal structures and spatial layouts. The design of the adjusting elongated hole 31 allows the connecting bracket 3 to flexibly adjust the position of the boss 11, thereby ensuring that the thread collection device can be adapted to various models and specifications of sewing machines, improving the device's versatility and market applicability, and reducing user operating costs. The design of the adjusting elongated hole 31 makes the installation and removal of the boss 11 simpler and faster. Maintenance personnel or operators can quickly fix the boss 11 to the connecting bracket 3 through the adjusting elongated hole 31, or easily remove it when maintenance or replacement is required. This quick installation and removal method greatly saves time and effort, improves equipment maintenance efficiency, and reduces production downtime caused by equipment repairs.

[0051] Furthermore, the boss 11 is provided with at least two mounting holes 14, and a connecting screw 5 is provided in the mounting hole 14. The connecting screw 5 connects the boss 11 and the connecting bracket 3 through the fixing plate 6.

[0052] It should be noted that the boss 11 has at least two mounting holes 14, which are connected to the fixing plate 6 and the connecting bracket 3 by connecting screws 5. This multi-point fixing method significantly enhances the structural stability of the boss 11. Compared with single-point fixing, multi-point fixing can distribute external forces more evenly, reduce loosening or deformation caused by external forces or long-term use, and ensure that the wire suction component 1 maintains a stable position and posture during operation. As a key structure for fixing the wire suction component 1, the boss 11 is assembled and fixed to the connecting bracket 3 and the fixing plate 6 by two connecting screws 5 and mounting holes 14, ensuring the stability of the wire suction component 1 during wire cutting and suction processes. It will not be displaced or vibrated due to suction or shearing forces, thereby improving the efficiency and quality of wire collection.

[0053] The suction tube 2 is angled upwards relative to the line connecting the two fixing holes, allowing the suction to act more smoothly on the thread end, reducing airflow resistance at the connection point, and improving the efficiency of suction utilization. It also helps reduce thread bounce or scattering caused by airflow impact, further improving the stability of thread collection.

[0054] In the above embodiment, the connecting bracket 3 includes two horizontally arranged horizontal plates and one vertically arranged vertical plate. The vertical plate is perpendicular to the horizontal plates and is used to connect the two horizontal plates.

[0055] Understandably, the connecting bracket 3 consists of two horizontally arranged horizontal plates and one vertically arranged vertical plate. The vertical plate is perpendicular to the horizontal plates and is used to connect the two horizontal plates. This frame structure provides stable support, allowing the connecting bracket 3 to provide sufficient support while minimizing its space occupation. It can effectively utilize the limited space inside the sewing machine, making it adaptable to various models and specifications of sewing machines, thus improving its versatility and adaptability.

[0056] An adjustment elongated hole 31 is provided at the mounting position of the connecting bracket 3 and the thread suction component 1. The adjustment elongated hole 31 is an elongated hole used to adjust the front and back position of the thread suction component 1, allowing the thread suction component 1 to be flexibly adapted and optimized according to different sewing needs and equipment specifications. For example, when sewing products with different buttonhole lengths, the front and back position of the thread suction component 1 can be adjusted to ensure that the thread cutting position is always kept above the annular groove, thereby improving the efficiency and quality of thread collection and meeting diverse sewing production needs.

[0057] During installation, the suction tube 2 on one side is fitted into the chamfered structure 13. Then, the connecting screws 5 are passed through the suction piece 1, the connecting bracket 3, and the fixing plate 6 in sequence, adjusted to the appropriate position, and then fixed. This design optimizes the airflow guidance path, allowing the suction to act more smoothly on the cord end, reducing airflow resistance at the connection point, and improving the efficiency of suction utilization. At the same time, this design also helps to reduce cord rebound or scattering caused by airflow impact, further improving the stability of cord collection.

[0058] Based on the above embodiment, the housing 4 is provided with a cutter assembly 7, which is located below the wire cutting notch 9.

[0059] It should be noted that positioning the cutter assembly 7 below the thread-cutting notch 9 ensures that the scissors can precisely cut from the root of the thread end, avoiding uneven or incomplete cuts caused by loose thread ends. This results in uniform and neatly cut thread ends, meeting the requirements of high-precision sewing. It also ensures that the thread ends can be quickly removed from the sewing area after cutting, preventing them from scattering and accumulating inside the sewing machine. Simultaneously, due to the close spatial fit between the cutter assembly 7 and the thread end collection device, the thread end is immediately sucked in and discharged by the suction device 1 after cutting, achieving seamless integration of thread cutting and thread end collection, improving the efficiency and thoroughness of thread end collection. The location of the cutter assembly 7 below the thread-cutting notch 9 ensures that the thread end will not fall into other parts of the sewing machine due to gravity after cutting, reducing thread residue inside the machine, lowering the risk of equipment jamming and malfunction, and ensuring the continuous and stable operation of the sewing machine.

[0060] The placement of the cutter assembly 7 below the thread-cutting notch 9 makes the entire thread-collecting device more compact, reducing its size and weight, saving valuable space inside the sewing machine, and allowing it to be more flexibly adapted to different models and specifications of sewing machines, thus improving its versatility and adaptability. The close integration of the cutter assembly 7 and the thread-collecting device enables a unified design, reducing the number of parts and connection points, simplifying the structure, lowering complexity and manufacturing costs, while also improving reliability and lifespan.

[0061] In the above embodiment, the cutter assembly 7 includes a cutter holder assembly 71 and a cutter 72. The cutter holder assembly 71 is disposed on the housing 4, and the cutter 72 is disposed vertically on the cutter holder assembly 71, with the cutting edge of the cutter 72 facing the wire cutting notch 9.

[0062] Understandably, the cutter 72 is vertically mounted on the cutter holder assembly 71, with its blade facing the thread cutting notch 9, ensuring that the cutter 72 can accurately cut from the root of the thread end. The vertically mounted cutter 72 provides stable cutting force, ensuring that the thread end is neatly cut off, avoiding problems such as loose thread ends or incomplete cutting caused by improper cutting angles, and significantly improving the quality and accuracy of thread cutting.

[0063] In a preferred embodiment, the wire suction structure 12 is disposed on one side of the cutter 72.

[0064] It should be noted that the thread suction structure 12 is located on one side of the cutter 72, allowing for precise alignment with the cutting position. This ensures that the thread end is quickly sucked into the channel of the thread suction component 1 at the moment of cutting, preventing the thread end from scattering and accumulating inside the sewing machine. The side suction design allows the suction force to act directly on the cutting position, reducing the possibility of the thread end scattering due to external force during cutting. This ensures that the thread end is sucked in and discharged along a predetermined path, further improving the stability and reliability of thread end collection. Compared to traditional thread suction designs, side suction can more effectively capture thread ends, improving the efficiency and thoroughness of thread end collection.

[0065] A sewing machine includes a housing 4, on which the aforementioned thread collection device is provided.

[0066] Understandably, the thread end collecting device precisely aligns with the thread cutting notch 9, ensuring that the thread end is straightened and fixed in a specific position before cutting. This allows the scissors to cut precisely from the root of the thread, avoiding uneven or incomplete cuts caused by loose thread ends, significantly improving the quality and precision of thread cutting. The efficient collection function of the thread end collecting device reduces the scattering and accumulation of thread ends inside the sewing machine, lowering the risk of equipment jamming and malfunctions, and ensuring the continuous and stable operation of the sewing machine. Simultaneously, it allows the thread ends to be more easily sucked in and discharged by the suction element 1, improving the efficiency and thoroughness of thread end collection.

[0067] In the above embodiment, a table 8 is also provided on the housing 4. The table 8 is provided with a thread cutting notch 9 and a scissor assembly 10, with the scissor assembly 10 located on one side of the thread cutting notch 9. The scissor assembly 10 is installed on the table 8. The thread suction component 1 is assembled with the connecting bracket 3 and then installed and fixed on the housing 4, and is tightly installed and fixed to the cutter 72. The cutter 72 is installed on the cutter holder assembly 71. The thread suction component 1 can adjust its own position through the adjustment elongated hole 31 on the connecting bracket 3. When sewing different buttonhole lengths, the thread suction structure 12 can follow the scissor assembly 10 to achieve the purpose of sucking up the straight thread head for easy cutting and collecting the cut thread head.

[0068] It should be noted that the scissor assembly 10 is located on one side of the thread-cutting notch 9, allowing for precise alignment with the cutting position. The close fit between the scissor assembly 10 and the thread-cutting notch 9 ensures that the thread end can be quickly removed from the sewing area after cutting, reducing the scattering and accumulation of thread ends inside the sewing machine, lowering the risk of equipment jamming and malfunction, and ensuring continuous and stable operation of the sewing machine. The location of the scissor assembly 10 on one side of the thread-cutting notch 9 makes the entire device more compact, saving valuable space inside the sewing machine and allowing for more flexible adaptation to different models and specifications of sewing machines, improving the device's versatility and adaptability.

[0069] In addition to the sewing machines disclosed in the above embodiments, the structures of other parts of the sewing machine are described in the prior art and will not be repeated here.

[0070] In summary, the thread collection device provided by this utility model generates negative pressure in the vacuum generator before the scissor assembly 10 operates, thereby creating negative pressure in the suction tube 2 and the suction component 1 to straighten the thread end. Then, the scissor assembly 10 operates, cutting the thread end. Because the thread end is straightened vertically downward relative to the table surface 8, and the scissor assembly 10 operates parallel to the table surface 8, the scissor assembly 10 cuts the thread end almost at its root. The thread is straightened during cutting, ensuring the quality of the cut. The thread end is ultimately collected from the suction structure 12, improving thread cleaning efficiency. The integrated suction design allows for simultaneous cutting and cleaning, reducing manual intervention and lowering equipment failure rates. This device has a compact structure, occupies little space, and is suitable for industrial and household sewing machines.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0072] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] The thread collection device and sewing machine provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
