Description

Technical Field

[0001] This utility model relates to the field of needle transmission equipment, and in particular to a multi-track parallel transmission device for needles. Background Technology

[0002] As a slender and precise component, the needle is widely used in the textile and garment industries. It comes in a variety of specifications and in large quantities. In the assembly line operation of needle production, processing and assembly, the needle transmission link is crucial and directly affects the overall production efficiency and product quality.

[0003] Traditional needle transport devices mostly use a single track for conveying needles, which has obvious limitations: on the one hand, a single track can only transport a small number of needles at a time, resulting in low transport efficiency and making it difficult to meet the needs of large-scale production; on the other hand, when it is necessary to transport needles of different specifications, the positioning mechanism of the traditional device often cannot be well adapted, which can easily lead to needle shaking, deviation, or even falling, seriously affecting the stability of the transport. Therefore, it is necessary to improve these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figure 1-6 This utility model discloses a multi-track parallel transmission device for machine needles, comprising a mounting frame 1 and a first conveyor belt 2 located at the lower end of the mounting frame 1. The mounting frame 1 facilitates the installation of guide rails 3. Multiple sets of guide rails 3 are installed on the inner side of the mounting frame 1, which facilitate the coordination with transport positioning blocks 11. Each set of guide rails 3 has a second conveyor belt on its inner side, and each second conveyor belt has a positioning mechanism. The positioning mechanism includes multiple positioning blocks 11 installed on the second conveyor belt and mounting grooves opened inside the positioning blocks 11, which facilitate the placement of machine needles. A V-shaped flexible plate 14 is hinged at the opening of the mounting groove, which facilitates the clamping of the machine needles. Two guide plates 12 are installed at an angle downward inside the mounting groove, which restrict the movement trajectory of the gravity ball 13. Two gravity balls 13 are also installed inside the mounting groove, which facilitate the compression of the malleable soft sheet 14. The positioning block 11 is slidably connected to the inner side of the guide rail 3. The mounting frame 1 consists of a first support frame 4 at the front end and a second support frame 5 at the rear end. The length of the mounting frame 1 can be easily adjusted through the first support frame 4 and the second support frame 5. Two connecting plates are fixedly connected to the inner sides of the first support frame 4 and the second support frame 5. The two sets of corresponding connecting plates are connected by threads. Support legs 6 are installed in the middle of both sides of the mounting frame 1, which helps to improve the stability of the device.

[0022] In this utility model, two limiting blocks 7 are installed on the support leg 6. The limiting blocks 7 have a through groove. The connecting plate is located in the limiting groove. The limiting blocks 7 have a threaded hole for cooperating with the connecting plate. A motor 8 is installed on one side of the second support frame 5. The motor 8 can drive the first gear 9 and the first conveyor belt 2 to rotate. One end of the output shaft of the motor 8 is connected to the transmission roller of the first conveyor belt 2. The first gear 9 is installed on the output shaft of the motor 8. The first gear 9 can drive the second gear 10 to rotate. The upper end of the first gear 9 is engaged with the second gear 10. The second gear 10 can drive the second conveyor belt to rotate. The second gear 10 is connected to the transmission roller of the second conveyor belt through a rotating shaft. Each set of second conveyor belts corresponds to a set of second gears (10). Multiple sets of guide rails 3 are connected to each other in sequence by bolts. The sides of the guide rails 3 on both sides are fixedly connected to the inner side of the mounting frame 1.

[0023] Working Principle: When using this invention, first connect the power supply to the device and start the motor 8. The output shaft of the motor 8 begins to rotate. One end of the output shaft of the motor 8 is connected to the transmission roller of the first conveyor belt 2, thereby driving the first conveyor belt 2 to rotate. At the same time, the first gear 9 installed on the output shaft of the motor 8 rotates accordingly. The first gear 9 meshes with the second gear 10 for transmission. The second gear 10 is connected to the transmission roller of the second conveyor belt, thereby driving multiple sets of second conveyor belts to rotate synchronously. Place the needle on the V-shaped flexible plate 14 of the positioning mechanism. Since two guide plates 12 are installed downwards at the top of the mounting groove, and two gravity balls 13 are installed in the mounting groove, the gravity balls 13 roll along the guide plates 12 under the action of gravity, compressing the V-shaped flexible plate. Plate 14 is used to fit the surface of the needle, achieving stable clamping of the needle. The first conveyor belt 2 and the second conveyor belt operate synchronously, driving the needle placed on the positioning mechanism to move. The positioning block 11 slides into contact with the inner side of the guide rail 3, ensuring that the positioning mechanism moves stably along the guide rail 3 during transmission and preventing the needle from deviating. When the positioning block reaches above the first conveyor belt 2 and rotates, the center of gravity of the gravity ball 13 changes, and the needle falls to the first conveyor belt 2. If it is necessary to adjust the length of the mounting frame 1, the threaded hole on the limit block 7 can be loosened, and the first support frame 4 and the second support frame 5 can be moved so that the two sets of corresponding connecting plates move relative to each other. After adjusting to the appropriate length, the threaded hole on the limit block 7 is tightened to fix the connecting plate, thus completing the adjustment of the length of the mounting frame 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
