A device for fixing needles and bead tubes

Abstract

This application discloses a fixing pin and bead processing device. The fixing pin includes a guide section and at least one stop section. The minimum radial dimension of the stop section is greater than the radial dimension of the guide section, which has the smallest radial dimension, much smaller than the radial dimension of the feed tube. The guide section acts as a guide, allowing the fixing pin to be quickly and accurately aligned with the opening of the feed tube. The variable-diameter stop section has a locking effect with the opening of the feed tube, providing radial restraint to prevent radial wobbling. Simultaneously, the stop section seals the opening of the feed tube, preventing the molten adhesive material between the guide section and the feed tube from overflowing. A storage section connects to the stop section; this storage section is variable-diameter, with its minimum radial dimension greater than the maximum radial dimension of the stop section. The storage section guides the flow direction of the adhesive material outside the feed tube, preventing the adhesive material from accumulating at the opening of the feed tube and causing adjacent feed tubes to stick together.

Description

Technical Field

[0001] This utility model generally relates to the field of computer embroidery machine technology, and more particularly to a device for fixing needles and bead tubes. Background Technology

[0002] Beaded embroidery is a special embroidery technique used in computerized embroidery machines. It enhances the three-dimensionality and decorative effect of the design by incorporating beads (slender, tubular decorative elements) during the embroidery process. This technique is widely used in high-end clothing, home textiles, and handicrafts. The addition of beads gives the embroidered pattern a distinct three-dimensional effect, enhancing its visual impact; the luster and texture of the beads add a sense of luxury and artistry to the embroidery; furthermore, the beads are made of materials such as metal, plastic, or glass, possessing strong wear resistance and durability.

[0003] In related technologies, glass bead tubes are cut and segmented manually, which is inefficient, time-consuming, labor-intensive, and can easily cause arm injuries and safety accidents. Utility Model Content

[0004] This utility model provides a fixing pin for a bead tube processing device, including a guide section and at least one stop section, wherein the guide section is of equal diameter;

[0005] The stop section is connected to the guide section. The stop section has a variable diameter, and the minimum radial dimension of the stop section is greater than or equal to the radial dimension of the guide section.

[0006] As an alternative implementation, the fixing pin further includes a storage material section connected to the stop section, the storage material section having a variable diameter, and the minimum radial dimension of the storage material section being greater than or equal to the maximum radial dimension of the stop section.

[0007] As one possible implementation, the stop segment includes a cone shape.

[0008] As one possible implementation, the storage section includes a cone shape.

[0009] As an implementation method, the second-direction cross-section of the stop section is a first trapezoid, and the second-direction cross-section of the storage material section is a second trapezoid, wherein the slope of the side of the first trapezoid is greater than the slope of the side of the second trapezoid, and the second-direction cross-section is parallel to the length extension direction of the fixing pin.

[0010] As an implementation method, at least two stop sections and at least two storage material sections are provided, the stop sections and the storage material sections are arranged alternately along the direction from the guide section to the stop section, and the radial dimension of each section gradually increases.

[0011] As an implementation method, the maximum radial dimension of the storage section near the guide section is less than or equal to the minimum radial dimension of the stop section away from the guide section.

[0012] As an implementation, the maximum radial dimension of the stop section near the guide section is smaller than the minimum radial dimension of the stop section away from the guide section; the maximum radial dimension of the storage material section near the guide section is smaller than the minimum radial dimension of the storage material section away from the guide section.

[0013] This utility model also provides a bead tube processing device, including the aforementioned fixing pin.

[0014] In the above-described scheme, the minimum radial dimension of the stop section is greater than that of the guide section, which has the smallest radial dimension, much smaller than that of the feed tube. The guide section acts as a guide, allowing the fixing pin to quickly and accurately align with the opening of the feed tube. Simultaneously, the radial dimension of the guide section is smaller than that of the feed tube, and both radial dimensions can accommodate the molten adhesive material, thus firmly fixing the feed tube to the fixing pin. A locking effect exists between the variable-diameter stop section and the opening of the feed tube, providing radial restraint to prevent radial movement. Simultaneously, the stop section seals the opening of the feed tube, preventing the molten adhesive material between the guide section and the feed tube from overflowing. A storage section connects to the stop section; this storage section is a variable-diameter section, with its minimum radial dimension greater than that of the stop section. The storage section guides the flow direction of the adhesive material outside the feed tube, preventing adhesive material from accumulating at the opening of the feed tube and causing adjacent feed tubes to stick together.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used above to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] like Figure 4 and Figure 5 As shown, the bead processing device includes a first fixed seat assembly 10, a second fixed seat assembly 20 and a pipe cutting assembly 30. The first fixed seat assembly 10 and the second fixed seat assembly 20 are spaced apart in a first direction (i.e., the left-right direction), and the pipe cutting assembly 30 is correspondingly arranged with respect to the second fixed seat assembly 20.

[0027] The first fixing seat assembly 10 includes a first fixing seat 12, on which a plurality of fixing pins 11 are arranged in the same direction. The fixing pins 11 are used to insert into the end of the material tube, and the rotation of the fixing pins 11 causes the material tube to rotate. The first direction is perpendicular to the arrangement direction of the fixing pins 11. The second fixing seat assembly supports the material tube corresponding to each fixing pin 11, so that several material tubes are arranged in the same direction.

[0028] The tube cutting assembly 30 includes multiple cutters arranged in the same direction. Each cutter corresponds to a fixed pin 11. The cutter arrangement direction is parallel to the fixed pin arrangement direction. The cutter cooperates with the second fixed seat assembly 20 to cut the tube and form a tube bead.

[0029] The bead processing device also includes a material box assembly 40, which includes a material box containing adhesive material. The material box cooperates with the fixing pin 11 so that the fixing pin 11 contacts the adhesive material. Thus, before the bead is inserted into the fixing pin 11, the adhesive material on the fixing pin 11 increases the strength of the bead connection, preventing insecure insertion and thus aiding subsequent cutting processes, such as ensuring bead stability, a smooth cut, and accurate bead dimensions.

[0030] The following embodiments provide a detailed description of the fixing pin 11:

[0031] like Figures 1-3 As shown, the fixing pin 11 includes a guide section 111 and at least one stop section 112. The guide section 111 has a constant diameter. The stop section 112 is connected to the guide section 111 and has a variable diameter. The minimum radial dimension of the stop section 112 is greater than the radial dimension of the guide section 111.

[0032] For example, such as Figure 1 As shown, the fixing pin 11 includes a guide section 111, a stop section 112, and a support section 114, which are connected sequentially. The guide section 111 has a constant diameter, and its first-direction cross-section is circular, perpendicular to the extension direction of the fixing pin 11. The stop section 112 has a variable diameter along the direction from the guide section 111 to the stop section 112, with its radial dimension gradually increasing along this direction. The first-direction cross-section of the stop section 112 is circular, and it can be, but is not limited to, tapered or stepped. The minimum radial dimension of the stop section 112 is greater than or equal to the radial dimension of the guide section 111, and the stop section 112 is coaxially arranged with the guide section 111.

[0033] When the fixing pin 11 is inserted into the feed tube, the guide section 111 of the fixing pin 11 is located inside the feed tube. Part of the stop section 112 is located inside the feed tube, while the remaining part is outside the feed tube, abutting against the opening of the feed tube. Since the minimum radial dimension of the stop section 112 is greater than the radial dimension of the guide section 111, and the radial dimension of the guide section 111 is the smallest, it is much smaller than the radial dimension of the feed tube. The guide section 111 acts as a guide, allowing the fixing pin 11 to quickly and accurately align with the opening of the feed tube. Simultaneously, the radial dimension of the guide section 111 is smaller than the radial dimension of the feed tube; the combined radial dimensions of both can accommodate the molten adhesive, thus firmly fixing the feed tube to the fixing pin 11. The variable-diameter stop section 112 has a locking effect with the opening of the feed tube, providing radial restraint to prevent radial movement of the feed tube. At the same time, the stop section 112 can seal the opening of the material tube and prevent the molten adhesive material between the guide section 111 and the material tube from overflowing.

[0034] Optionally, such as Figure 1 As shown, the stop section 112 is tapered, and its radial dimension gradually increases from the guide section 111 to the stop section 112. The second-direction cross-section of the stop section 112 is a first isosceles trapezoid, and the second-direction cross-section is parallel to the length extension direction of the fixing pin 11. This helps to ensure that the axis of the feed tube and the fixing pin 11 are substantially coincident.

[0035] The fixing pin 11 also includes a storage material section 113 connected to the stop section 112. The storage material section 113 is a variable diameter section, and the minimum radial dimension of the storage material section 113 is greater than the maximum radial dimension of the stop section 112.

[0036] like Figure 1 As shown, guide section 111, stop section 112, and storage section 113 are connected in sequence, with storage section 113 located on the outside of the material pipe. Storage section 113 has a variable diameter along the direction from guide section 111 to stop section 112, with its radial dimension gradually increasing along this direction. The first cross-section of storage section 113 is circular, and storage section 113 can be, but is not limited to, conical or stepped shapes. The minimum radial dimension of storage section 113 is greater than the maximum radial dimension of stop section 112, and stop section 112, guide section 111, and storage section 113 are coaxially arranged.

[0037] In practical applications, the vertically positioned fixing pin 11 contacts the adhesive material inside the material box. The amount of adhesive material in the box may fluctuate. When the amount of adhesive material in the box is large, a significant amount of adhesive material adheres to the stop section 112 of the fixing pin 11. During the insertion of the fixing pin 11 into the feed tube, some adhesive material is squeezed out of the feed tube. Combined with the large amount of adhesive material adhering to the stop section 112, such as... Figure 2As shown, there is a risk of adhesion between adjacent feed tubes. Based on this, the storage section 113 can guide the flow direction of the adhesive material located outside the feed tube, avoiding the accumulation of adhesive material at the opening of the feed tube and causing adjacent feed tubes to stick together.

[0038] The storage section 113 is conical, and its radial dimension gradually increases from the guide section 111 to the stop section 112. The cross-section of the storage section 113 in the second direction is a second isosceles trapezoid, and the slope of the side of the first isosceles trapezoid is greater than the slope of the side of the second isosceles trapezoid. This helps the storage section 113 to collect or contain the adhesive material located outside the material pipe.

[0039] As one possible implementation, the fixing pin 11 is provided with at least two stop sections 112 and at least two storage sections 113, with the stop sections 112 and storage sections 113 arranged alternately along the direction from the guide section 111 to the stop sections 112. The radial dimension of each section gradually increases, and the maximum radial dimension of the storage section 113 closer to the guide section 111 is less than or equal to the minimum radial dimension of the stop section 112 farther from the guide section 111.

[0040] like Figure 3 As shown, the fixing pin 11 includes a guide section 111, two stop sections 112, two storage material sections 113, and a support section 114. The guide section 111, the first stop section 112a, the first storage material section 113a, the second stop section 112b, the second storage material section 113b, and the support section 114 are arranged sequentially.

[0041] The radial dimension of the guide section 111 is less than or equal to the radial dimension of the first stop section 112a, the radial dimension of the first stop section 112a is less than or equal to the radial dimension of the first remaining material, the radial dimension of the first remaining material is less than or equal to the radial dimension of the second stop section 112b, and the radial dimension of the second stop section 112b is less than or equal to the radial dimension of the second remaining material. In this way, the fixing pin 11 can fix two different radial dimensions of the material tube, thereby helping to broaden the adaptability of the fixing pin 11.

[0042] In summary, this application achieves this by having a minimum radial dimension greater than that of the guide section 111, which has the smallest radial dimension, significantly smaller than that of the feed tube. The guide section 111 acts as a guide, allowing the fixing pin 11 to quickly and accurately align with the opening of the feed tube. Simultaneously, the smaller radial dimension of the guide section 111 allows for the filling of molten adhesive material, firmly securing the feed tube to the fixing pin 11. The variable-diameter stop section 112 engages with the opening of the feed tube, providing radial restraint and preventing radial movement. Simultaneously, the stop section 112 seals the opening, preventing the molten adhesive material between the guide section 111 and the feed tube from overflowing. A storage section 113 connects to the stop section 112; this storage section 113 is a variable-diameter section, with a minimum radial dimension greater than that of the stop section 112. The storage section 113 can guide the flow direction of the adhesive material located outside the material pipe, and prevent the adhesive material from accumulating at the opening of the material pipe and causing two adjacent material pipes to stick together.

[0043] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
