Description

Technical Field

[0001] This utility model belongs to the field of sewing machine needle management equipment, specifically an intelligent needle delivery device for sewing machine needles. Background Technology

[0002] Garment production requires sewing machine needles. During the sewing process, needles may break due to prolonged use or improper operation. Once a needle breaks, it needs to be replaced. If the broken needle is not replaced promptly and left on clothing, it can lead to injuries if the garment is sold. Therefore, it is necessary to replace broken needles promptly at the source to avoid this situation. However, needle breakage is common in large garment manufacturing enterprises, and it is impossible to guarantee the complete retrieval of broken needles manually. In the event of an injury, the broken needle cannot be traced. Therefore, comprehensive management of sewing machine needles is necessary.

[0003] The invention patent with patent number 201920378170.1 discloses a smart sewing machine needle manager, including a cabinet. The front of the cabinet is provided with a switching power supply, a face camera, an operation display screen, and a needle ejection mechanism. A needle receiving platform is provided in front of the needle ejection mechanism. The inside of the cabinet is provided with a main control board and a waste needle recycling mechanism. The face camera, operation display screen, needle ejection mechanism, and waste needle recycling mechanism are all electrically connected to the main control board. The switching power supply provides power to other devices.

[0004] The patent disclosure has certain shortcomings. The needle ejection mechanism in this solution requires a power unit corresponding to the number of needle clamp assemblies to eject the sewing machine needles. Due to the large size of the electromagnets and the excessive gap between adjacent needle clamp assemblies, the number of needle clamp assemblies that can be installed is limited, increasing equipment costs and resulting in low needle ejection efficiency. Furthermore, the solution only mentions one electromagnet driving method, where a stroke electromagnet drives a push rod to eject the sewing machine needle, which limits its application scenarios and leaves considerable room for improvement. Summary of the Invention

[0005] This utility model addresses the aforementioned technical problems by providing an intelligent needle ejection device for sewing machine needles. The needle ejection drive component can move to the selected needle clamp component and remove the needle from the corresponding needle clamp component, thereby saving equipment costs and improving needle ejection efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an intelligent needle ejection device for sewing machine needles, including a needle ejection drive assembly and multiple needle clamp assemblies installed in parallel. The needle clamp assembly includes a needle clamp plate for storing the needle and a needle clamp base. A swing rod that can swing horizontally is provided between the bottom of the needle clamp plate and the needle clamp base. The needle ejection drive assembly includes a sliding plate that is slidably installed on a first mounting base and can move to any needle clamp assembly. The sliding plate is equipped with a linear module and a servo motor for controlling the moving position of the sliding plate. The linear module is equipped with a module motor and a needle ejection drive plate that cooperates with the swing rod to eject the needle.

[0007] To optimize the above technical solution, the present invention also includes the following improved technical solutions.

[0008] The aforementioned swing arm has a drive rod inserted through its rear end, and a protrusion is formed at the front end of the needle drive plate. A first inclined edge is formed on one side of the protrusion to abut against the drive rod.

[0009] The aforementioned first mounting base is provided with a horizontally arranged helical rack and a first slide rail, the servo motor is provided with a helical gear that meshes with the helical rack, and a first slider that cooperates with the first slide rail is provided below the sliding plate.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Figures 1 to 5 The diagram shown is a structural schematic of this utility model.

[0023] The reference numerals in the attached drawings are as follows: first mounting base 1, needle clamp plate 2, first needle groove 2a, needle outlet 2b, needle clamp left plate 2c, needle clamp right plate 2d, first long groove 2e, needle clamp base 3, second needle groove 3a, needle pressing block 4, counterweight block 5, counterweight moving handle 6, swing arm 7, third needle groove 7a, rotating shaft 8, drive rod 9, fastener 10, tension spring 11, sliding plate 12, servo motor 13, linear module 14, module motor 15, needle output drive plate 16, helical rack 17, first slide rail 18, helical gear 19, first slider 20, moving block 21, protrusion 22, first inclined side 23.

[0024] The present invention discloses an intelligent needle ejection device for a sewing machine needle, comprising multiple needle clamp assemblies and a needle ejection drive assembly installed in parallel. The needle ejection drive assembly can move to the selected needle clamp assembly and remove the machine needle from the corresponding needle clamp assembly.

[0025] Multiple needle clip assemblies are arranged side by side at the front end of the first mounting base 1. In this embodiment, the number of needle clip assemblies is thirty sets, and the number of needle clip assemblies can be appropriately adjusted according to the cost and efficiency of the device.

[0026] The needle clamp assembly includes a needle clamp plate 2 for storing machine needles and a needle clamp base 3. The needle clamp plate 2 is fixed on the needle clamp base 3, and the needle clamp base 3 is fixed to the front end of the first mounting base 1. The needle clamp plate 2 has a first needle groove 2a for the machine needle to slide down, and the needle clamp base 3 has a second needle groove 3a. The first needle groove 2a and the second needle groove 3a are offset from each other.

[0027] The needle clamp 2 has a needle insertion port 2b at its upper end for inserting machine needles, and the needle insertion port 2b communicates with the first needle groove 2a. The needle clamp 2 includes a left needle clamp plate 2c and a right needle clamp plate 2d. The left needle clamp plate 2c has a vertically arranged first elongated groove 2e. A needle pressing block 4 for fixing the machine needle is provided in the first needle groove 2a. A counterweight block 5 is provided on the outside of the left needle clamp plate 2c, and the counterweight block 5 is connected to the needle pressing block 4. The counterweight block 5 has a counterweight moving handle 6 for easy installation. As the number of machine needles in the needle clamp 2 gradually decreases, the needle pressing block 4 gradually moves downward along the first elongated groove 2e, and the counterweight moving handle 6 on the left side of the left needle clamp plate 2c moves synchronously with the needle pressing block 4. When it is necessary to add a machine needle to the needle clamp 2, the counterweight moving handle 6 is moved upward, and then the machine needle is inserted through the needle insertion port 2b.

[0028] A horizontally swinging lever 7 is provided between the bottom of the needle clamp plate 2 and the needle clamp base 3. The lever 7 is rotatably mounted on the needle clamp base 3 via a rotating shaft 8. A drive rod 9 that cooperates with the needle delivery drive assembly is provided at the rear end of the lever 7. The lower end of the drive rod 9 is fixed by a fastener 10. The needle delivery drive assembly drives the lever 7 to swing horizontally.

[0029] A tension spring 11 is provided between the swing arm 7 and the needle clamp base 3. One end of the tension spring 11 is connected to the swing arm 7, and the other end of the tension spring 11 is connected to the needle clamp base 3. When the swing arm 7 swings relative to the needle clamp base 3, the swing arm 7 pulls the tension spring 11 to produce deformation, and the tension spring 11 can drive the swing arm 7 to return to the initial state.

[0030] The front end of the lever 7 has a third needle groove 7a, which can coincide with or be offset from the first needle groove 2a, and can also coincide with or be offset from the second needle groove 3a. Initially, the front end of the lever 7 is above the second needle groove 3a, and the third needle groove 7a coincides with the second needle groove 3a. When the front end of the lever 7 swings below the needle clamp 2, the third needle groove 7a coincides with the first needle groove 2a, and the needle in the needle clamp 2 enters the third needle groove 7a along the first needle groove 2a. Subsequently, the lever 7 gradually returns to its initial state, the third needle groove 7a is offset from the first needle groove 2a, and the front end of the lever 7 closes the first needle groove 2a. This continues until the third needle groove 7a coincides with the second needle groove 3a, at which point the needle in the third needle groove 7a falls into the second needle groove 3a, achieving automatic needle ejection.

[0031] The needle-out driving assembly is located at the rear end of the first mounting base 1. The needle-out driving assembly includes a sliding plate 12 slidably mounted on the first mounting base 1, a servo motor 13 mounted on the sliding plate 12, and a linear module 14. The linear module 14 is provided with a module motor 15 and a needle-out driving plate 16 that cooperates with the swing arm 7 to outfeed needles.

[0032] The first mounting base 1 is provided with a horizontally arranged helical rack 17 and a first slide rail 18. The servo motor 13 is provided with a helical gear 19 that meshes with the helical rack 17. Below the sliding plate 12, there is a first slider 20 that cooperates with the first slide rail 18. The servo motor 13 drives the helical gear 19 to rotate, and the helical gear 19 meshes with the helical rack 17, thereby driving the sliding plate 12 to move horizontally along the first slide rail 18 to the corresponding needle clip assembly.

[0033] The module motor 15 is fixed to one end of the linear module 14. The linear module 14 is provided with a moving block 21, and the needle-out driving plate 16 is fixed on the moving block 21. The front end of the needle-out driving plate 16 has a protrusion 22, and one side of the protrusion 22 has a first inclined edge 23 that abuts against the driving rod 9. The module motor 15 drives the needle-out driving plate 16 back and forth, and the driving rod 9 at the rear end of the swing rod 7 moves obliquely along the first inclined edge 23 of the needle-out driving plate 16, thereby driving the swing rod 7 to swing horizontally.

[0034] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
