Description

Technical Field

[0001] The utility model relates to the technical field of machine needle management, in particular to a needle outlet box. Background Art

[0002] In the current sewing industry, factories generally implement strict needle management procedures to ensure smooth production and worker safety. This process typically includes the distribution and registration of needles, as well as the recovery of broken needles, and these tasks are often performed by dedicated personnel. This series of measures not only improves production quality but also effectively prevents safety accidents that may arise from improper needle management.

[0003] In order to further optimize the needle management process and improve management efficiency, a variety of technical solutions have been proposed and applied in actual production. For example, patent CN202322335867.X discloses a sewing machine needle management cabinet, which integrates modules such as a power switch, face recognition, an operation display, and a needle disk mechanism to realize the automated management of machine needles. Among them, a needle removal platform is provided under the needle disk mechanism, and its needle removal method draws on the principle of a handwheel gun. However, this management method has significant shortcomings: the needles need to be placed one by one in the needle holes of the needle disk, which is not only cumbersome and inefficient, but also prone to omissions, resulting in employees being unable to obtain new needles smoothly when they receive needles. In addition, since the number of needles that can be placed on a needle disk is limited, when the demand for needles is relatively frequent, managers need to frequently perform needle replenishment operations, which undoubtedly reduces overall work efficiency. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a needle ejection box, which can solve the problem of cumbersome and inefficient needle insertion.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A needle ejection box, comprising:

[0007] A box body, wherein the interior of the box body is a hollow structure, and a needle outlet is provided on one side of the box body;

[0008] A needle feeding member, the needle feeding member is slidably arranged in the cavity structure, and a needle groove is provided on the top surface of the needle feeding member;

[0009] A driving member is connected to the needle feeding member in a transmission manner so as to drive the needle feeding member to slide out of the cavity structure and into the cavity structure along the needle outlet, and when the needle feeding member slides out of the cavity structure, the needle groove slides out of the needle outlet.

[0010] By adopting the above solution, when adding needles, the needles can be directly placed into the cavity structure, which effectively improves the efficiency of loading needles. The number of needles loaded can be effectively increased according to the size of the cavity structure, thereby reducing the frequency of needle delivery. In addition, the needle feeding part of the needle box carries the needles through the needle groove on the top surface. When the needle feeding part slides along the slide in the cavity structure, the needle groove slides out of the needle outlet, thereby realizing the automatic delivery of the needle. Compared with the cumbersome steps of needle removal and placing needles one by one in the prior art, this structure greatly improves the efficiency of needle management.

[0011] Furthermore, the driving member includes a first lever, a second lever, a transfer lever and a return spring, the first lever and the second lever are assembled on the transfer lever, the second lever is located at both ends of the transfer lever, one end of which is rotatably connected to the needle feeding member, and the other end is connected to one end of the return spring, and the other end of the return spring is connected to the box body, the first lever is located outside the box body, and the two ends of the transfer lever are rotatably assembled in the cavity structure;

[0012] When the first lever is moved, the transfer lever rotates along with the rotation of the first lever, and the second lever is driven by the transfer lever to rotate about the axis of the transfer lever to drive the needle feed member to slide out of the needle outlet, and when the second lever rotates, the return spring is stretched;

[0013] During reset, the reset spring contracts, driving the second lever to rotate with the axis of the transfer rod as the rotation axis, and at the same time driving the needle feeding member to be retracted from the needle outlet into the cavity structure. During the reset movement of the transfer rod, the first lever is driven to reset.

[0014] By adopting the above solution, the entire needle feeding process can be triggered by only moving the first lever located outside the box body. The degree of automation is high, the operation steps are greatly simplified, and the needle removal efficiency and stability are improved.

[0015] Furthermore, the needle groove is arranged on the side close to the needle outlet, the needle feeding member is provided with a rotating shaft pull rod on the side away from the needle groove, the second shift rod is provided with a fork head toward one end of the rotating shaft pull rod, the middle of the fork head has a rotating groove, and the rotating shaft pull rod is rotatably assembled in the rotating groove.

[0016] By adopting the above scheme, the fork on the second lever and the rotating shaft pull rod are linked to ensure that when the second lever is driven to rotate by the transfer rod, the needle feed part can be reliably driven to slide out of or into the cavity structure along the needle outlet. The linkage structure is not only simple, but also convenient for the assembly of the second lever and the rotating shaft pull rod.

[0017] Furthermore, assembly grooves are provided on both sides of the box body, and both ends of the adapter rod are rotatably assembled in the assembly grooves.

[0018] By adopting the above scheme, by providing assembly grooves on both sides of the box body and assembling both ends of the adapter rod in the assembly grooves, on the one hand, it is convenient for the assembly of the adapter rod, and on the other hand, it ensures the stability of the adapter rod during operation, reducing the displacement of the adapter rod caused by mechanical vibration or improper operation, thereby ensuring the reliability and accuracy of the movement of the needle feeding member.

[0019] Furthermore, there are two second shift rods, which are respectively assembled on both sides of the adapter rod. The needle feeding member is provided with pivot pull rods on both sides, and the second shift rods and the pivot pull rods are connected in one-to-one correspondence.

[0020] By adopting the above scheme, by providing two second shift rods and connecting them in one-to-one correspondence with the pivot pull rods on both sides of the needle feeding member, it is possible to ensure the balance of the needle feeding member during the sliding process, reducing the skew phenomenon that may be caused by unilateral force, making the needle feeding action more stable and reliable.

[0021] Furthermore, a hook-shaped portion is provided at one end of the second shift rod away from the needle feeding member, and one end of the return spring is hung on the hook-shaped portion.

[0022] By adopting the above scheme, the design of the hook-shaped portion enables one end of the return spring to be easily hung on it, simplifying the installation process of the return spring, completing the assembly without complex fixing means, and also preventing the return spring from easily slipping out from the hook-shaped portion.

[0023] Furthermore, a limiting block is provided at the bottom of the box body. The limiting block is provided on the side of the hook-shaped portion away from the needle outlet. When the needle feeding member moves to the outside of the cavity structure in place, the hook-shaped portion fits with the limiting block.

[0024] By adopting the above scheme, the function of the limiting block is to prevent the needle feeding member from continuing to move outward when it completely slides out of the cavity structure to the predetermined position, preventing damage to the needle or the needle feeding member caused by overshoot. This ensures the position accuracy and safety of the needle when it is sent out.

[0025] Furthermore, the box body further includes a bottom plate. The hook-shaped portion extends out of the bottom plate, and the limiting block is provided on the bottom plate.

[0026] By adopting the above scheme, the design that the hook-shaped portion extends out of the bottom plate makes the installation of the return spring more compact, reduces the occupied space, makes the overall structure more compact, and is conducive to realizing the functions of the equipment in a limited space.

[0027] Furthermore, a transition surface is provided on the side of the needle groove away from the needle outlet, and the slope of the transition surface is lower than the slope of the inclined surface on the side of the needle groove close to the needle outlet.

[0028] By adopting the above solution, the needle groove is designed to have a volume that can accommodate more than one needle but less than two needles, enabling the needle outlet box to be compatible with machine needles of different diameters, improving the versatility and adaptability of the device. When the needle feeding member moves outward, since the slope of the transition surface is lower than the slope of the inclined surface on the side close to the needle outlet, this can ensure that during the needle feeding process, the second needle exits the needle groove more smoothly, reducing jamming and resistance, enabling the machine needle to smoothly remain in the cavity structure, and avoiding the problem of the machine needle getting stuck in the needle groove.

[0029] Furthermore, a stopper is provided on the side of the box body at the needle outlet. One end of the stopper is connected above the needle outlet, and the other end is connected to the end face of the needle feeding member facing the needle outlet, for preventing the needle from popping out of the needle groove.

[0030] By adopting the above solution, the design of the stopper can effectively prevent the machine needle from popping out of the needle groove due to vibration or other external forces during the feeding process, ensuring the safe feeding of the machine needle. By setting the stopper, the operation process of feeding the machine needle is simplified, enabling the operator not to worry about the accidental popping out of the machine needle during use, and improving the simplicity of the operation.

[0031] In summary, the needle outlet box provided by the present utility model has the following technical effects:

[0032] 1. When adding needles, simply place the needles directly into the cavity structure, effectively improving the efficiency of loading machine needles, and effectively increasing the number of machine needles loaded according to the size of the cavity structure, thereby reducing the frequency of machine needle delivery;

[0033] 2. The needle feeding member of the needle outlet box carries the machine needle through the needle groove on the top surface. When the needle feeding member slides along the slideway in the cavity structure, the needle groove slides out of the needle outlet, thus realizing the automatic delivery of the machine needle. This structure greatly improves the efficiency of machine needle management compared to the cumbersome steps of the prior art for delivering needles and placing machine needles one by one.

DETAILED DESCRIPTION

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See Figures 1 - 5The utility model discloses a needle outlet box, including a box body 1, a needle feeding member 2 and a driving member. The interior of the box body 1 is a cavity structure 11, and a needle outlet 12 is provided on one side of the box body 1. The needle feeding member 2 is slidably arranged in the cavity structure 11, and a needle groove 21 is provided on the top surface of the needle feeding member 2. The driving member is transmission-connected with the needle feeding member 2 to drive the needle feeding member 2 to slide out of the cavity structure 11 and into the cavity structure 11 along the needle outlet 12, and in the process of the needle feeding member 2 sliding out of the cavity structure 11, the needle groove 21 slides out of the needle outlet 12.

[0045] Specifically, the interior of the box body 1 is a cavity structure 11, which is convenient for loading the machine needle. A needle outlet 12 is provided on one side of the box body 1, and the needle outlet 12 connects the inside and outside of the box body 1. The needle feeding member 2 is slidably arranged in the cavity structure 11 and can slide to the outside of the box body 1 through the needle outlet 12. The top surface of the needle feeding member 2 is provided with a needle groove 21 for accommodating the machine needle, and the needle groove 21 moves to the outside of the box body 1 as the needle feeding member 2 moves, and the needle groove 21 also moves to the outside of the box body 1. Then, by tilting the needle feeding member 2 and / or the box body 1 relative to the horizontal plane, the machine needle slides out of the needle groove 21 under the action of gravity, completing the automatic removal of the machine needle. Alternatively, the machine needle can be directly grabbed by other means. It should also be noted that the volume of the needle groove 21 can be freely set as needed. For example, if one needle needs to be removed at a time, the volume of the needle groove 21 can be set to be larger than the volume of one needle and smaller than the volume of two needles. This design of the volume of the needle groove 21 can be used to remove needles with larger diameters when the needle model is changed. Of course, other volumes of the needle groove 21 can also be used and freely set according to user needs. The driving member is connected to the needle feeding member 2 for driving the needle feeding member 2 to reciprocate along the needle outlet 12.

[0046] In addition, the needle outlet 12 set on one side of the box body 1 can also be set at the top of the box body 1. The driving part pushes the needle feeding part 2 to move upward until the needle groove 21 is pushed out of the needle outlet 12. Subsequently, the box body 1 or the needle feeding part 2 is tilted, or other structures are used to facilitate the removal of the needle in the needle groove 21 to complete the needle removal operation.

[0047] See Figures 1 - 4 As shown, in some embodiments, the driving member includes a first lever 31, a second lever 32, a transfer lever 33 and a return spring 34. The first lever 31 and the second lever 32 are assembled on the transfer lever 33. The second lever 32 is located at both ends of the transfer lever 33, one end of which is rotatably connected to the needle feeding member 2, and the other end is connected to one end of the return spring 34. The other end of the return spring 34 is connected to the box body 1. The first lever 31 is located outside the box body 1, and both ends of the transfer lever 33 are rotatably assembled in the cavity structure 11.

[0048] When the first lever 31 is toggled, the transfer lever 33 rotates along with the rotation of the first lever 31. The second lever 32 is driven by the transfer lever 33 to rotate about the axis of the transfer lever 33, thereby driving the needle feeding member 2 to slide out from the needle outlet 12. When the second lever 32 rotates, the return spring 34 is stretched.

[0049] During reset, the return spring 34 contracts, driving the second lever 32 to rotate about the axis of the transfer lever 33. At the same time, it drives the needle feeding member 2 to retract from the needle outlet 12 into the cavity structure 11. During the reset movement of the transfer lever 33, the first lever 31 is driven to reset.

[0050] In some embodiments, for the convenience of assembling the needle feeding member 2 and the fork head 321, the needle groove 21 is provided on one side close to the needle outlet 12. A rotating shaft pull rod 22 is provided on the side of the needle feeding member 2 away from the needle groove 21. The fork head 321 is provided at one end of the second lever 32 facing the rotating shaft pull rod 22. A rotating groove 3211 is provided in the middle of the fork head 321, and the rotating shaft pull rod 22 is rotatably assembled in the rotating groove 3211.

[0051] Specifically, through the linkage between the fork head 321 on the second lever 32 and the rotating shaft pull rod 22, it is ensured that when the second lever 32 is driven to rotate by the transfer lever 33, the needle feeding member 2 can be reliably driven to slide out or slide into the cavity structure 11 along the needle outlet 12. This linkage structure is not only simple but also facilitates the assembly of the second lever 32 and the rotating shaft pull rod 22.

[0052] In some embodiments, assembly grooves 13 are provided on both sides of the box body 1. The two ends of the transfer lever 33 are respectively rotatably assembled in the assembly grooves 13, and the transfer lever 33 can rotate in the assembly grooves 13.

[0053] Specifically, by providing the assembly grooves 13 on both sides of the box body 1 and assembling the two ends of the transfer lever 33 in the assembly grooves 13, on the one hand, it is convenient for the assembly of the transfer lever 33, and on the other hand, it ensures the stability of the transfer lever 33 during operation, reducing the displacement of the transfer lever 33 caused by mechanical vibration or improper operation, thereby ensuring the reliability and accuracy of the movement of the needle feeding member 2.

[0054] In some embodiments, to improve the stability when driving the needle feeding member 2, two second levers 32 are provided and are respectively assembled on both sides of the transfer lever 33. Rotating shaft pull rods 22 are provided on both sides of the needle feeding member 2, and the second levers 32 and the rotating shaft pull rods 22 are connected in a one-to-one correspondence.

[0055] Specifically, by providing two second levers 32 and connecting them to the rotating shaft pull rods 22 on both sides of the needle feeding member 2 in a one-to-one correspondence, it can ensure the balance of the needle feeding member 2 during the sliding process, reduce the skew phenomenon that may be caused by unilateral force, and make the needle feeding action more stable and reliable.

[0056] In some embodiments, in order to facilitate the assembly of the return spring 34 and the stability of the return spring 34 after assembly, a hook portion 322 is provided at one end of the second lever 32 away from the needle feeding member 2, and one end of the return spring 34 is hung on the hook portion 322.

[0057] Specifically, the design of the hook portion 322 enables one end of the return spring 34 to be easily hung thereon, simplifying the installation process of the return spring 34. The assembly can be completed without complex fixing means, and it can also prevent the return spring 34 from easily slipping out of the hook portion 322.

[0058] In some embodiments, a limiting block 141 is provided at the bottom of the box body 1. The limiting block 141 is provided on the side of the hook portion 322 away from the needle outlet 12. When the needle feeding member 2 moves to the outside of the cavity structure 11 in place, the hook portion 322 abuts against the limiting block 141.

[0059] Specifically, the function of the limiting block 141 is to prevent the needle feeding member 2 from continuing to move outward when the needle feeding member 2 completely slides out of the cavity structure 11 to reach the predetermined position, preventing damage to the machine needle or the needle feeding member 2 due to overshoot. This ensures the position accuracy and safety of the machine needle when it is sent out.

[0060] In some embodiments, the box body 1 further includes a bottom plate 14. The hook portion 322 extends out of the bottom plate 14, and the limiting block 141 is provided on the bottom plate 14.

[0061] Specifically, the design that the hook portion 322 extends out of the bottom plate 14 makes the installation of the return spring 34 more compact, reducing the occupied space, making the overall structure more compact, and facilitating the realization of the functions of the device in a limited space.

[0062] Refer to Figure 5 As shown, in some embodiments, in order to facilitate the smooth retraction of the redundant machine needles in the needle slot 21, a transition surface 23 is provided on the side of the needle slot 21 away from the needle outlet 12, and the slope of the transition surface 23 is lower than the slope of the inclined surface on the side of the needle slot 21 close to the needle outlet 12.

[0063] Specifically, in order to improve the versatility and adaptability of the device, the needle slot 21 is generally designed to have a volume that can accommodate more than one needle but less than two needles, so that the needle outlet box can be compatible with machine needles of different diameters. When the needle feeding member 2 moves outward, since the slope of the transition surface 23 is lower than the inclined surface on the side close to the needle outlet 12, this can ensure that during the needle feeding process, the second needle exits the needle slot 21 more smoothly, reducing jamming and resistance, enabling the machine needle to smoothly remain in the cavity structure 11, and avoiding the problem of the machine needle getting stuck in the needle slot 21.

[0064] In some embodiments, in order to avoid the influence of the jumping needle on the needle ejection, a baffle 15 is provided on one side of the needle ejection port 12 of the cartridge body 1. One end of the baffle 15 is connected above the needle ejection port 12, and the other end is connected to the end face of the needle feeding member 2 facing the needle ejection port 12 to prevent the needle from popping out of the needle groove 21.

[0065] Specifically, the design of the baffle 15 can effectively prevent the sewing needle from popping out of the needle groove 21 due to vibration or other external forces during the feeding process, ensuring the safe feeding of the sewing needle. By setting the baffle 15, the operation process of feeding the sewing needle is simplified, so that the operator does not have to worry about the accidental ejection of the sewing needle during use, improving the simplicity of the operation.

[0066] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
