[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 The embroidery machine for home textiles shown includes a machine head, a support base 1 mounted on the machine head, and further includes:

[0025] The drive mechanism 2 is located at the bottom of the support base 1; preferably, the drive mechanism 2 is a cylinder or a servo motor. By setting the drive mechanism, the lifting mechanism can be moved up and down.

[0026] The limiting cylinder 3 is located below the drive mechanism 2, and the embroidery needle body 4 is installed inside the limiting cylinder 3;

[0027] The embroidery needle can be clamped and fixed by setting a limiting sleeve. Specifically, the center of the limiting sleeve has an insertion hole, and a limiting sleeve is set in the insertion hole. The needle is fixed by setting the limiting sleeve. The limiting sleeve is made of rubber and has a certain degree of elasticity, thereby strengthening the fixing effect on the needle and preventing the needle from shaking during use, thus ensuring the uniformity of the trajectory.

[0028] The lifting mechanism 5, which is connected to the drive mechanism, drives the limit cylinder 3 to reciprocate in the vertical direction.

[0029] By setting up a lifting mechanism, the limiting cylinder is driven to reciprocate in the vertical direction, thereby achieving stable operation of the embroidery needle.

[0030] like Figure 2 As shown, the lifting mechanism 5 includes guide rods 51 symmetrically distributed on both sides of the limiting cylinder 3. A sliding frame 52 is movably sleeved on the guide rods 51. The center of the sliding frame 52 is matched with the limiting cylinder 3. Its top is connected to the output end of the drive mechanism. The drive mechanism drives the sliding frame 52 to reciprocate in the vertical direction, and then drives the limiting cylinder to reciprocate through the sliding frame.

[0031] By setting a guide rod, the sliding frame can move along the guide rod, thereby driving the limiting cylinder to move up and down, ensuring the normal operation of the embroidery needle. The sliding frame also limits and fixes the limiting cylinder, ensuring its movement trajectory does not deviate or wobble, thus ensuring the uniform movement trajectory of the embroidery needle. The limiting cylinder, on the one hand, drives the embroidery needle in reciprocating motion, and on the other hand, limits and fixes the embroidery needle, preventing problems such as needle head wobbling leading to uneven embroidery stitches during high-speed embroidery, thereby ensuring the aesthetics and quality of home textile products. The drive mechanism drives the sliding frame to reciprocate vertically, ensuring the stability of the embroidery process.

[0032] Furthermore, U-shaped grooves 53 are symmetrically provided on opposite sides of the sliding frame 52. The U-shaped grooves 53 are fitted around the guide rod 51, and the sliding frame 52 slides up and down along the guide rod through the U-shaped grooves 53.

[0033] The sliding frame is a cuboid that is open at both the top and bottom. A U-shaped groove is opened in the center of its opposite side. The sliding frame is placed outside the guide rod through the U-shaped groove and can move up and down along the guide rod.

[0034] Specifically, a cylindrical through hole is provided in the center of the sliding frame 52, and the limiting cylinder 3 is fitted into the through hole. A first slide rail 54 and a second slide rail 55 are distributed on the outer wall of the through hole with the horizontal line as the center. A protrusion 31 is symmetrically provided on the outer wall of the limiting cylinder 3, and the protrusion 31 can slide along the first slide rail 54 and the second slide rail 55.

[0035] By opening a through hole in the center of the sliding frame, the limiting cylinder can move up and down along the through hole, thus driving the embroidery needle body to work stably during the movement. In order to ensure the normal movement of the limiting cylinder, two slides are opened on the outer wall of the through hole, and corresponding protrusions are set on the limiting cylinder, so that the protrusions can slide along the first slide and the second slide.

[0036] Specifically, both slides No. 1 and No. 2 are serrated and staggered, allowing the protrusion to rotate along the two slides. During rotation, the limiting cylinder reciprocates in the vertical direction. Initially, the protrusion is located in slide No. 2. When the sliding frame moves downward, it will drive the limiting cylinder downward. When the sliding frame reaches its maximum stroke, the protrusion moves into slide No. 1 and then into slide No. 2 along slide No. 1, thus performing reciprocating motion.

[0037] Preferably, slide 54 is serrated, and slide 54 and slide 55 are staggered.

[0038] By setting two serrated slides that are staggered, the protrusion can move within the space formed by the two slides, and the slides restrict the movement trajectory of the protrusion. In this process, the limiting cylinder is driven to reciprocate.

[0039] Preferably, the top of the guide rod 51 is fastened to the first limiting block 6 and the bottom is fastened to the second limiting block 7. The first limiting block 6 is installed at the bottom of the drive mechanism, and the top surface of the first limiting block 6 is fastened to the support seat through the connecting rod 8. The second limiting block 7 is sleeved outside the limiting cylinder.

[0040] To ensure the smooth movement of the sliding frame, a first limit block and a second limit block are installed at the top and bottom of the guide rod, respectively, to restrict the movement of the sliding frame. The first limit block is installed below the drive mechanism, and the second limit block is installed outside the limit cylinder to ensure both the smooth movement of the sliding frame and the travel of the limit cylinder. The second limit block is movably connected to the limit cylinder, and the first limit block is connected to the support base via a connecting rod, ensuring that the drive mechanism can drive the lifting mechanism to move normally.

[0041] Specifically, a square plate 56 is provided on the top of the sliding frame 52. The bottom corner of the square plate 56 is connected to the sliding frame through a connecting block 57, and the center of the top surface is connected to the output end of the drive mechanism.

[0042] To ensure the normal movement of the sliding frame, a square plate is installed at the top of the sliding frame. The sliding frame is connected to the drive mechanism through the square plate, so that when the drive mechanism is activated, it can move the square plate, which in turn moves the sliding frame along the guide rod. By setting a connecting block, the stability of the connection between the square plate and the sliding frame is ensured, guaranteeing that it can perform normal reciprocating motion under the drive mechanism.

[0043] Example 2

[0044] like Figure 3 As shown, a clamping mechanism is provided inside the limiting cylinder 3. The clamping mechanism clamps and fixes the embroidery needle body to ensure its stability during operation. The clamping mechanism includes oppositely arranged arc-shaped clamps. The other end of the arc-shaped clamps is connected to the protrusion by screws. The arc-shaped clamps clamp and limit the needle body to prevent shaking during use.

[0045] The embroidery needle body is fitted with a shock-absorbing sleeve. This sleeve is composed of three layers of materials with different properties, from the inside out. The innermost layer is a rubber buffer layer made of natural rubber. Natural rubber possesses excellent elasticity, allowing it to rapidly deform elastically when the needle vibrates at high speed, absorbing and dispersing vibrational energy, effectively reducing the impact of vibration on the needle shaft and embroidery stitches. The rubber buffer layer fits tightly against the needle shaft, initially absorbing and buffering the initial energy of the vibration.

[0046] The middle layer is a honeycomb-shaped damping layer, made of aluminum alloy. This honeycomb structure allows it to deform and disperse energy when subjected to external impacts, utilizing its numerous tiny honeycomb units. When vibrations that the rubber buffer layer cannot fully absorb are transmitted to the honeycomb damping layer, the honeycomb structure disperses the vibration energy in three-dimensional space through its elastic deformation, further weakening the vibration intensity and providing a more stable working environment for the needle bar. Simultaneously, the high strength of the aluminum alloy ensures the overall structural stability of the damping sleeve, making it less prone to structural damage even under long-term high-frequency vibration impacts.

[0047] The outermost layer is a wear-resistant ceramic coating, which is uniformly applied to the surface of the honeycomb shock-absorbing layer using a plasma spraying process. This coating has extremely high hardness, allowing the outer surface of the shock-absorbing sleeve to effectively resist frequent friction with fabric, embroidery thread, etc., greatly improving the wear resistance of the sleeve. During embroidery, the fabric and needle constantly rub against each other; the wear-resistant ceramic coating maintains its smoothness and integrity for a long time, reducing the decline in shock absorption performance caused by wear, thereby extending the service life of the shock-absorbing sleeve and the entire needle assembly.

[0048] The purpose of this utility model is to provide an embroidery machine for home textiles. By setting a limiting cylinder, the embroidery needle is limited and fixed. At the same time, the normal operation of the needle is ensured by setting a drive mechanism and a lifting mechanism. The clamping and fixing of the limiting sleeve inside the limiting cylinder ensures that the needle will not move or shake during use, which improves the stability of the needle during operation, makes the embroidery stitches uniform, and ensures the beauty and quality of home textile products.

[0049] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
