Description

Technical Field

[0001] This utility model relates to the field of embroidery machines, and in particular to an integrated structure of shuttle box and base for small embroidery machines. Background Technology

[0002] As an important type of automated embroidery equipment, the small embroidery machine is widely used in home workshops, small garment factories, and handicraft production due to its compact structure, ease of operation, and relatively low cost. It can efficiently and accurately complete complex embroidery patterns on various fabrics, meeting the market demands for personalized customization and small-batch production.

[0003] A small embroidery machine mainly consists of the following core components: a base, which serves as the basic support structure for the entire machine, providing a mounting platform and stability for other components; a shuttle box, mounted on the base, whose core function is to house and drive the embroidery shuttle, ensuring reliable interweaving of the bobbin thread and the needle thread to form stitches; and an embroidery head, located above or in front of the base in the working area, containing a mechanism for driving the needle bar up and down, a thread supply system, and a control system. The head drives the needle to penetrate the fabric, cooperating with the shuttle in the shuttle box to complete the embroidery action.

[0004] In traditional small embroidery machine designs, the base machining mainly involves two directions: top and bottom. This includes machining the top surface, drilling mounting holes, and machining the bottom support structure. The process is relatively simple and straightforward. However, to fulfill its function, especially for mounting the crucial thread-locking electromagnet, the traditional shuttle box typically requires mounting holes machined on the side wall of the neck. This prevents the base and shuttle box from being machined together in a single, simple top-bottom process. Separate manufacturing not only increases the number of parts, machining steps, and costs, but also requires additional assembly steps. Accumulated assembly errors can affect the overall machine's accuracy and reliability. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides an integrated structure of shuttle box and base for small embroidery machine, which can effectively solve the technical problem that the base and shuttle box need to be processed separately and then assembled.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The shuttle box and base of the small embroidery machine are integrated into one structure, including the embroidery machine base. The embroidery machine base is provided with a first receiving cavity with an upward opening. A support platform is provided in the receiving cavity. A working area is provided in front of the embroidery machine base. The surface of the embroidery machine base is integrally formed with a shuttle box, which includes a base and a neck. The base is located on the surface of the support platform. The neck extends horizontally into the working area and is provided with an upward-opening groove. The base is provided with a second receiving cavity with an upward opening. The bottom surface of the second receiving cavity is provided with a mounting hole for installing a thread-attaching electromagnet. The mounting hole penetrates the bottom surface of the base and the top surface of the support platform.

[0008] Furthermore, the edge of the first receiving cavity is provided with a recessed positioning step, and the surface of the positioning step is evenly distributed with a number of threaded holes.

[0009] Furthermore, both the base portion and the neck portion are provided with shaft holes for mounting the shuttle shaft, and all shaft holes are coaxially arranged.

[0010] Furthermore, the bottom surface of the embroidery machine base is provided with symmetrically distributed support feet.

[0011] Furthermore, the surface of the suspension neck is provided with wiring grooves.

[0012] Furthermore, the bottom surface of the support platform is provided with reinforcing ribs.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: By moving the mounting hole for installing the electromagnet from the side wall of the neck of the traditional shuttle box to the bottom surface of the second receiving cavity of the base, the shuttle box can be completed only through vertical machining. This is fully compatible with the process characteristics of the base itself, which mainly relies on vertical machining. Therefore, the entire base, including the shuttle box structure, can be integrally formed through vertical machining in a single clamping process. This eliminates the assembly step between the base and the shuttle box, significantly reducing material, processing, and assembly costs, and improving production efficiency. The integrated structure eliminates the connection interface between separate parts, making the base and shuttle box a robust whole. This greatly enhances the overall rigidity and mechanical strength, reduces vibration and deformation that may occur during high-speed operation, and improves the stability and embroidery accuracy of the embroidery machine.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is combined with Figures 1-5 The integrated shuttle box and base structure of the small embroidery machine of this utility model is described in detail below:

[0022] The shuttle box and base of the small embroidery machine are integrated into one structure, including the embroidery machine base 1. The bottom surface of the embroidery machine base 1 is provided with symmetrically distributed support feet 10. The embroidery machine base 1 is provided with an upward-facing first receiving cavity 101. A support platform 102 is provided inside the receiving cavity. A working area 2 is provided in front of the embroidery machine base 1. The surface of the embroidery machine base 1 is integrally formed with a shuttle box 3. The shuttle box 3 includes a base part 301 and a neck 302. The base part 301 is located on the surface of the support platform 102. The neck 302 extends horizontally into the working area 2. The neck 302 is provided with an upward-facing groove 4. The base part 301 is provided with an upward-facing second receiving cavity 5. The bottom surface of the second receiving cavity 5 is provided with a mounting hole 6 for installing a thread-attaching electromagnet. The mounting hole 6 penetrates the bottom surface of the base part 301 and the top surface of the support platform 102.

[0023] By moving the mounting hole 6 for installing the thread-fastening electromagnet from the side wall of the neck 302 of the conventional shuttle box to the bottom surface of the second receiving cavity 5 of the base 301, the shuttle box 3 can be completed solely through vertical machining. This is fully compatible with the process characteristics of the base itself, which primarily relies on vertical machining. Therefore, the entire base, including the shuttle box 3 structure, can be integrally formed through vertical machining in a single clamping operation. This eliminates the assembly step between the base and the shuttle box 3, significantly reducing material, processing, and assembly costs, and improving production efficiency. The integrated structure eliminates the connection interface between separate parts, making the embroidery machine base 1 and the shuttle box 3 a robust whole. This greatly enhances the overall rigidity and mechanical strength, reduces vibration and deformation that may occur during high-speed operation, and improves the stability and embroidery accuracy of the embroidery machine.

[0024] The first receiving cavity 101 has a recessed positioning step 103 at its edge. The surface of the positioning step 103 is evenly distributed with several threaded holes 104. The positioning step 103 provides a precise positioning reference for the base cover plate, ensuring that the cover plate can be accurately and quickly installed in place and completely cover the first receiving cavity 101. The evenly distributed threaded holes 104 facilitate the use of bolts to securely and reliably lock the cover plate onto the embroidery machine base 1, preventing the cover plate from loosening or shifting during equipment operation. This design simplifies the cover plate installation process, improves assembly efficiency and reliability, and protects the components inside the receiving cavity from dust or foreign matter intrusion.

[0025] Both the base 301 and the neck 302 are provided with shaft holes 7 for mounting the shuttle shaft. All shaft holes 7 are coaxially arranged, providing uniform and stable multi-point support for the shuttle shaft that is installed through it. This significantly reduces the radial runout and vibration of the shuttle shaft during high-speed rotation, ensuring extremely smooth and stable operation of the embroidery shuttle, effectively reducing noise and wear, thereby greatly improving embroidery accuracy and extending the service life of the shuttle shaft and related moving parts. The surface of the neck 302 is provided with wiring grooves 8, providing a dedicated and orderly routing channel for power lines, signal lines, etc., leading to the inside of the shuttle box 3, such as the thread-locking electromagnet or components near the working area 2. This design effectively avoids the risk of cables scattering or getting tangled on the high-speed moving neck 302 or nearby mechanisms, greatly improving the safety of equipment operation, reducing the risk of accidental cable breakage, wear, or interference, and making the internal wiring of the equipment neat and orderly, facilitating maintenance.

[0026] The bottom surface of the support platform 102 is provided with reinforcing ribs 9. These reinforcing ribs 9 can greatly enhance the rigidity of the support platform 102 against bending and torsional deformation, ensuring that it maintains excellent shape stability when subjected to complex dynamic loads from the shuttle box 3 and the embroidery machine head, such as the driving force of the rotary shuttle, the force of the electromagnet and the vibration of the equipment.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
