Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to an easy-to-maintain embroidery machine. Background Technology

[0002] An embroidery machine is an automated textile machinery device mainly used to embroider various patterns, texts and designs on various fabrics. The embroidery machine uses a computer control system to precisely control components such as motors. The motor drives the embroidery needles up and down through a transmission mechanism. At the same time, the fabric feeding mechanism precisely controls the movement of the fabric according to a preset program, so that the embroidery needles can embroider on the fabric according to the designed pattern.

[0003] Currently, the use of embroidery machines on the market requires selecting the appropriate embroidery needle based on the thickness of the fabric being processed. This is to ensure the quality of the embroidery work. By using embroidery needles that match the fabric thickness, problems such as broken needles and skipped threads during the embroidery process can be effectively reduced. Embroidery needles are usually removed and replaced manually. When replacing them, appropriate tools, such as screwdrivers, are generally required to loosen the device that fixes the embroidery needle, remove the old needle, and then correctly install and fix the new needle. This process takes a lot of time and effort. Manual operation may result in improper installation due to operator negligence or lack of skill. For example, the embroidery needle may not be installed vertically or fixed tightly, which may lead to problems such as needle breakage and thread tangling during the embroidery process, affecting the embroidery quality and even potentially damaging other parts of the embroidery machine. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-maintain embroidery machine that can automatically replace embroidery needles as needed, without the need for manual disassembly and installation, thereby improving the efficiency of embroidery needle replacement and reducing the possibility of improper installation during the replacement process.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses an easy-to-maintain embroidery machine. By incorporating a rotating replacement assembly, a drive motor rotates a round rod, which in turn drives a cylindrical gear. The cylindrical gear meshes with the round gear, causing the round gear to rotate as well. This allows the round gear to move the needle bar downwards, moving the embroidery needle at the bottom of the needle bar to the outside of the needle storage box. The round gear circulates on the round gear, driving the needle bar up and down. As the needle bar moves downwards, the embroidery needle, carrying the embroidery thread, pierces the fabric, forming a needle hole. When the rod moves upward, the embroidery needle is pulled out of the fabric, completing the piercing action. If embroidering on different fabrics, the insert rod is pulled upward, and then the rotating handle is rotated as needed. The rotation of the rotating handle moves the round hole, allowing different embroidery needles to be pushed to the use position through the round hole. The insert rod is then inserted into the round hole for positioning and fixation, thus completing the quick replacement of the embroidery needle. This device can automatically replace embroidery needles as needed, without the need for manual disassembly and installation, improving the efficiency of embroidery needle replacement and reducing the possibility of improper installation during the replacement process.

Detailed Implementation

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, an easy-to-maintain embroidery machine includes a needle storage box 1, a presser foot 2 installed at the bottom of the needle storage box 1, a cylindrical shell 3 fixedly connected to one side of the needle storage box 1, a rotating rod 4 rotatably connected inside the needle storage box 1, a needle plate 5 fixedly connected to the surface of the rotating rod 4, a plurality of fixed rods 6 fixedly connected to the top of the needle plate 5, a needle bar 7 slidably connected in each fixed rod 6, an embroidery needle 8 fixedly connected to the bottom of the needle bar 7, and a rotating replacement assembly provided inside the needle storage box 1.

[0022] The design of the needle storage box 1 and the presser foot 2 is used to protect multiple embroidery needles 8. By manually operating the handle 14, the rotating rod 4 is driven to rotate. Then, the rotating rod 4 drives the needle bar 7 and the embroidery needle 8 on the needle plate 5 to rotate to the appropriate position, so as to facilitate the replacement of the embroidery needle 8 and improve the replacement speed of the embroidery needle 8. The rotating replacement component includes a power unit installed inside the needle storage box 1 of the embroidery machine body to facilitate the quick replacement of the embroidery needle 8.

[0023] like Figure 1 and Figure 2As shown, the rotating replacement assembly includes two annular plates 9 fixedly connected to the inner wall of the needle storage box 1. Multiple cylindrical gears 10 are slidably connected to one side of the two annular plates 9 that are close to each other. Each cylindrical gear 10 is rotatably connected to the surface of the needle bar 7. A cylindrical gear 11 is meshed with the surface of one of the cylindrical gears 10. A round rod 12 is fixedly connected to the inner side of the round gear 11. The two ends of the round rod 12 are rotatably connected to the inner wall of the cylindrical shell 3. A motor 13 is fixedly installed on the top of the cylindrical shell 3, and the output end of the motor 13 is fixedly connected to the round rod 12.

[0024] Specifically, the drive motor 13 drives the round rod 12 to rotate, which in turn drives the cylindrical gear 11 to rotate. The cylindrical gear 11 meshes with the cylindrical gear 10, thus driving the cylindrical gear 10 to rotate. This allows the cylindrical gear 10 to move the needle bar 7 downward, moving the embroidery needle 8 at the bottom of the needle bar 7 to the outside of the needle storage box 1. The cylindrical gear 10 circulates on the cylindrical gear 11, driving the needle bar 7 to move up and down. As the needle bar 7 moves downward, the embroidery needle 8, carrying the embroidery thread, pierces the fabric. The needle bar 7 forms a needle hole in the fabric. When the needle bar 7 moves upward, the embroidery needle 8 is pulled out from the fabric, completing one piercing action. If embroidering on different fabrics, the insert bar 17 is pulled upward, and then the rotating handle 14 is rotated as needed. At this time, the rotating handle 14 drives the round hole 16 to move, so that different embroidery needles 8 can be pushed to the use position through the round hole 16. The insert bar 17 is inserted into the round hole 16 for limiting and fixing, thereby completing the quick replacement of the embroidery needle 8. The operation is simple and convenient, which increases the practicality of the embroidery machine.

[0025] like Figure 1 and Figure 4 As shown, a rotating handle 14 is installed on the top of the needle storage box 1, and the bottom end of the rotating handle 14 is fixedly connected to the top of the rotating rod 4. Multiple cross grooves 15 are opened around the top of the needle storage box 1. Circular holes 16 are opened around the top of the rotating handle 14 and the needle storage box 1, and a rod 17 is inserted into one of the circular holes 16.

[0026] The rotating handle 14 is used by the operator to manually grip and rotate the rotating rod 4, so as to rotate and change the embroidery needles 8 inside the needle storage box 1. The cross groove 15 is used to mark the position of the embroidery needles 8, so that the staff can quickly find and locate the required position of the embroidery needles 8, improve work efficiency, and improve the consistency of embroidery patterns and production efficiency. The design of the round hole 16 and the insertion rod 17 makes it easy for the insertion rod 17 to be pulled out from the round hole 16 to rotate the rotating handle 14. The insertion rod 17 is inserted into the round hole 16 to limit and fix the rotating handle 14, making the entire replacement process simpler and faster, and further enhancing the ease of use and practicality of the embroidery machine.

[0027] like Figure 2 As shown, two sponge wiping blocks 18 are fixedly connected to the bottom of the inner cavity of the needle storage box 1, and the inner side of the two sponge wiping blocks 18 has a convex structure.

[0028] Specifically, the sponge wiping block 18 is designed so that when the embroidery needle 8 is rotated and changed, the embroidery needle 8 can be wiped between the two sponge wiping blocks 18. During the embroidery process, the embroidery needle 8 will come into contact with various fabrics and threads, and may pick up fabric fibers, dust, oil and other impurities. If these impurities accumulate on the embroidery needle 8, they may affect the smoothness of the embroidery needle 8 piercing the fabric, resulting in uneven stitches, skipped stitches, broken threads and other problems, which will affect the quality and effect of the embroidery. Therefore, the sponge wiping block 18 is used to wipe the needle body and needle tip of the embroidery needle 8 in order to remove fabric fibers, dust and other impurities attached to the surface.

[0029] like Figure 4 As shown, two arc-shaped protective plates 19 are fixedly connected to the bottom of the inner cavity of the needle storage box 1, and the bottom of the embroidery needle 8 is slidably connected to the side of the two arc-shaped protective plates 19 that are close to each other.

[0030] The arc-shaped guard plate 19 is used to protect the tip of the embroidery needle 8. When the embroidery machine is not in operation or needs maintenance, the arc-shaped guard plate 19 can effectively prevent the needle tip from colliding with hard objects, thereby greatly extending the service life of the needle tip and ensuring the stability of embroidery quality.

[0031] like Figure 3 and Figure 4 As shown, a plurality of cleaning brushes 20 are fixedly connected to the inner wall of the needle storage box 1, and one side of each cleaning brush 20 is in contact with the surface of the embroidery needle 8.

[0032] Specifically, during embroidery, the needle eye may become obstructed due to tangled thread ends or clogged fabric fibers, thus affecting the needle's piercing effect. Through the ingenious design of the cleaning brush 20, when the embroidery needle 8 slides or rotates, its surface generates slight friction with the cleaning brush 20. This friction effectively removes impurities such as thread ends and fabric fibers adhering to the area around the needle eye, ensuring unobstructed passage.

[0033] The working principle of this utility model is as follows: First, the operator manually pulls the insert rod 17 upwards, and then rotates the handle 14 as needed. At this time, the rotation of the handle 14 drives the circular hole 16 to move, so that the required embroidery needle 8 can be pushed to the use position through the circular hole 16. The insert rod 17 is inserted into the circular hole 16 for limiting and fixing, thus completing the quick replacement of the embroidery needle 8. Then, the drive motor 13 drives the circular rod 12 to rotate, and the rotation of the circular rod 12 in turn drives the cylindrical gear 11 to rotate. The cylinder gear 10 rotates to drive the needle bar 7 downward, moving the embroidery needle 8 at the bottom of the needle bar 7 to the outside of the needle storage box 1. The cylinder gear 10 circulates on the cylindrical gear 11, driving the needle bar 7 to move up and down. The embroidery needle 8 passes through the fabric. When the needle bar 7 moves downward, the embroidery needle 8, carrying the embroidery thread, pierces into the fabric, forming a needle hole. When the needle bar 7 moves upward, the embroidery needle 8 is pulled out of the fabric, completing the piercing action and thus completing the rapid replacement of the embroidery needle 8.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
