Description

Technical Field

[0001] This utility model relates to the field of embroidery equipment, specifically to a material cup. Background Technology

[0002] In existing beaded embroidery machines, using a material cup to feed the embroidery beads is a common technique. In this technique, a rotating component is usually set on the bottom inner side of the material cup. The rotating component generally includes at least a horizontal turntable. The drive assembly drives the rotating component to rotate through the transmission process, which is used to stir the embroidery beads in the material cup, so that the moving embroidery beads pass through the guide wire for the subsequent feeding process.

[0003] In the prior art, rotating parts are usually fixed to the drive shaft, making it difficult to replace and maintain the rotating parts in the cup. Utility Model Content

[0004] To address the technical problems identified in the background section of the prior art, this utility model provides a material cup. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0005] A material cup includes: a rotating component and a driving assembly, the driving assembly being used to drive the rotating component to rotate, the rotating component having a vertical shaft hole in the center, and at least one limiting groove being formed on the inner sidewall of the shaft hole;

[0006] The driver components include:

[0007] The power module is used to provide power;

[0008] The rotating shaft is vertically connected to the power module, which drives the rotating shaft to rotate. The upper end of the rotating shaft is movably sleeved in the shaft hole, and the rotating shaft has an installation groove.

[0009] An elastic limiting element is installed in the mounting groove. When the elastic limiting element abuts against the inner wall of the shaft hole, the elastic limiting element can be compressed in the direction of the rotating shaft. When the elastic limiting element is opposite to the limiting groove, the elastic limiting element can enter the limiting groove, thereby restricting the relative rotation between the rotating shaft and the rotating part.

[0010] Furthermore, the mounting groove is vertically arranged, and the inner bottom surface of the mounting groove is inclined. The upper inner bottom surface of the mounting groove is closer to the center of the rotating shaft than the lower inner bottom surface. The elastic limiting component includes a vertical elastic plate and a limiting protrusion. The lower end of the elastic plate is fixedly arranged in the lower end of the mounting groove, and the upper end of the elastic plate is a free end that can enter the upper end of the mounting groove under the action of external force. The limiting protrusion is fixedly connected to the upper part of the elastic plate.

[0011] Furthermore, the lower end of the mounting groove is open, and the lower end of the elastic plate is provided with a horizontal lower limit edge that abuts against the lower end of the elastic plate. The drive assembly also includes a bushing, which is sleeved on the lower part of the rotating shaft. A bolt hole is provided through the horizontal side wall of the bushing. The bolt hole can be aligned with the elastic plate and the mounting groove. A fastening bolt is provided in the bolt hole, and the end of the fastening bolt can press against the side of the elastic plate to fasten the lower part of the elastic plate into the mounting groove.

[0012] Furthermore, auxiliary grooves are provided on both sides of the mounting groove. The auxiliary grooves are connected to the mounting groove and are located in the mounting groove directly opposite the bolt holes. The ends of the fastening bolts can enter the auxiliary grooves to press against the elastic plate.

[0013] Furthermore, the limiting protrusion is a vertically arranged arc-shaped plate, and the side of the arc-shaped plate facing away from the rotating shaft is an arc-shaped surface.

[0014] Furthermore, the upper end of the rotating shaft is provided with a clearance groove, and the clearance groove is connected to the upper end of the mounting groove. The upper end of the elastic plate is provided with a horizontal upper limit edge, which can enter the clearance groove and abut against the bottom surface of the clearance groove.

[0015] Furthermore, a turntable bushing is fixedly and coaxially arranged on the lower side of the center of the rotating part, and the rotating shaft is simultaneously movably sleeved in the shaft hole and the turntable bushing. A limiting groove extends and is provided on the inner side wall of the turntable bushing.

[0016] Furthermore, the drive assembly also includes a bearing, which is located below the turntable bushing. The rotating shaft is simultaneously movably sleeved in the shaft hole, the turntable bushing, and the bearing. The upper and lower ends of the limiting groove are open, and a limiting ring is provided on the rotating shaft, which abuts against the lower side of the bearing.

[0017] The beneficial effects of this utility model are as follows: In the actual use of the material cup of the bead embroidery machine, when installing the rotating part, align the shaft hole of the rotating part with the rotating shaft and insert the rotating shaft into the shaft hole. If the elastic limiting part is not aligned with the limiting groove, the inner wall of the shaft hole will squeeze the elastic limiting part, causing it to compress into the installation groove. At this time, by appropriately rotating the rotating part, the elastic limiting part can be moved to a position opposite to the limiting groove. The elastic limiting part will pop out and enter the limiting groove under its own elastic force, thereby restricting the relative rotation between the rotating shaft and the rotating part. After the power module is started, the rotating shaft can stably drive the rotating part to rotate, ensuring that the embroidery beads in the material cup are fully agitated and then smoothly pass through the guide wire, ensuring the stable progress of the subsequent feeding process.

[0018] When the rotating part needs to be replaced or maintained, simply pull the rotating part upwards, and the elastic limiter will slide out of the limit groove, allowing the rotating part to be removed from the shaft. After maintenance or replacement is completed, repeat the above installation steps to reassemble.

[0019] Compared to the shortcomings of existing technologies where rotating parts are fixedly connected to the drive shaft and require disassembly of a large number of structures for replacement and maintenance, this utility model, through the matching structure of elastic limiting parts and limiting grooves, not only achieves quick assembly and disassembly of rotating parts and shafts, greatly reducing maintenance difficulty and saving maintenance time, but also stably transmits power to ensure the working effect of the material cup agitating the embroidery beads. It takes into account practicality, stability and ease of maintenance, and effectively improves the overall performance and service life of the material cup of the embroidery bead embroidery machine.

[0027] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0028] This utility model provides a material cup, including: a rotating component 1 and a driving assembly. The driving assembly is used to drive the rotating component 1 to rotate. The rotating component 1 has a vertical shaft hole in the center, and at least one limiting groove 11 is provided on the inner side wall of the shaft hole. The driving assembly includes: a power module, a rotating shaft 2, and an elastic limiting component 3. The power module is used to provide power. The rotating shaft 2 is vertically connected to the power module, and the power module drives the rotating shaft 2 to rotate. The upper end of the rotating shaft 2 is movably sleeved in the shaft hole, and an installation groove 21 is provided on the rotating shaft 2. The elastic limiting component 3 is disposed in the installation groove 21. When the elastic limiting component 3 abuts against the inner side wall of the shaft hole, the elastic limiting component 3 can be compressed towards the rotating shaft 2. When the elastic limiting component 3 is opposite to the limiting groove 11, the elastic limiting component 3 can enter the limiting groove 11, thereby restricting the relative rotation between the rotating shaft 2 and the rotating component 1.

[0029] For details, please refer to Figures 1 to 5 In the actual use of the material cup of the bead embroidery machine, when installing the rotating part 1, align the shaft hole of the rotating part 1 with the rotating shaft 2 and insert the rotating shaft 2 into the shaft hole. If the elastic limiting part 3 is not aligned with the limiting groove 11, the inner wall of the shaft hole will squeeze the elastic limiting part 3, causing it to compress into the mounting groove 21. At this time, by appropriately rotating the rotating part 1, the elastic limiting part 3 can be moved to a position opposite to the limiting groove 11. The elastic limiting part 3 will pop out under its own elastic force and enter the limiting groove 11, thereby restricting the relative rotation between the rotating shaft 2 and the rotating part 1. After the power module is started, the rotating shaft 2 can stably drive the rotating part 1 to rotate, ensuring that the embroidery beads in the material cup are fully agitated and smoothly threaded into the guide wire, ensuring the stable progress of the subsequent feeding process. When it is necessary to replace or maintain the rotating part 1, simply pull the rotating part 1 upwards, and the elastic limiting part 3 will slide out of the limiting groove 11, allowing the rotating part 1 to be removed from the rotating shaft 2. After maintenance or replacement is completed, repeat the above installation steps to reassemble.

[0030] Further, refer to Figure 3 and Figure 4 The mounting groove 21 is vertically arranged, and the inner bottom surface of the mounting groove 21 is inclined. The upper inner bottom surface of the mounting groove 21 is closer to the center of the rotating shaft 2 than the lower inner bottom surface. The elastic limiting member 3 includes a vertical elastic plate 31 and a limiting protrusion 32. The lower end of the elastic plate 31 is fixedly arranged in the lower end of the mounting groove 21, and the upper end of the elastic plate 31 is a free end that can enter the upper end of the mounting groove 21 under the action of external force. The limiting protrusion 32 is fixedly connected to the upper part of the elastic plate 31.

[0031] With the above settings, when the elastic plate 31 is squeezed by the inner wall of the shaft hole, its upper end can bend and deform along the inclined surface toward the center of the rotating shaft 2, and be embedded in the space formed by the upper inclined surface of the mounting groove, so that the rotating shaft 2 and the elastic limiting member 3 can smoothly enter the shaft hole.

[0032] The elastic plate 31 can be made of the same material as the rotating shaft 2, such as elastic polymer or alloy materials. The elastic limiting member 3 is configured as a vertical elastic plate 31 and a limiting protrusion 32. When the elastic limiting member 3 pops out under its own elastic force and enters the limiting groove 11, and the rotating shaft 2 drives the rotating member 1 to rotate, the rotational torque is actually transmitted through the elastic limiting member 3. If the side surface area of ​​the elastic limiting member 3 in the rotational circumference direction that abuts against the limiting groove and mounting groove is small, and the structural strength of the torque transmission part is poor, then it will have a poor service life under torque transmission conditions. Therefore, the vertical elastic plate 31 can effectively transmit torque in the vertical limiting groove / mounting groove.

[0033] In other embodiments, the elastic limiting member 3 can also be designed in a similar way. For example, the elastic plate 31 can be set as a vertical block with a certain thickness, which is movably embedded in the mounting groove, and has the ability to elastically deform at the connection between the bottom surface of the mounting groove and the block.

[0034] In other embodiments, a limiting structure can be directly set in the mounting groove, and a spring is connected between the limiting structure and the bottom surface of the mounting groove. The limiting structure enters the limiting groove under the push of the spring.

[0035] Further, refer to Figure 3 and Figure 4 The lower end of the mounting groove 21 is open, and the lower end of the elastic plate 31 is provided with a horizontal lower limit edge 311. The lower limit edge 311 abuts against the lower end of the elastic plate 31. The drive assembly also includes a bushing 4, which is sleeved on the lower part of the rotating shaft 2. A bolt hole 41 is provided through the horizontal side wall of the bushing 4. The bolt hole 41 can be directly aligned with the elastic plate 31 and the mounting groove 21. A fastening bolt is provided in the bolt hole 41. The end of the fastening bolt can press against the side of the elastic plate 31 to fasten the lower part of the elastic plate 31 into the mounting groove 21.

[0036] With the above settings, the lower limit edge 311 provides initial positioning for the elastic plate 31, so that the lower end of the elastic plate 31 can be in a predetermined position. When the limiting protrusion 32 is pressed against and bent, the lower limit edge 311 is fastened to the lower end of the elastic plate 31, so the deformation of the elastic plate 31 will not change the position of the lower end of the elastic plate 31. The cooperation between the bushing 4 and the fastening bolt realizes the adjustable fixation of the lower part of the elastic plate 31. When the end of the fastening bolt presses against the side of the elastic plate 31, it can make the lower part of the elastic plate 31 fit tightly against the inner wall of the mounting groove 21, ensuring that the elastic plate 31 will not loosen during deformation.

[0037] In this embodiment, the drive assembly of the material cup of the beaded embroidery machine before the improvement has a plurality of bushings and bearings on the rotating shaft 2. In order to reduce the modification of the prototype machine before the improvement, reduce the improvement cost, and make use of the existing structure, it is considered to open bolt holes on the bushing 4 to fasten the lower part of the elastic element 31.

[0038] Further, refer to Figure 3 and Figure 4 Auxiliary grooves 22 are also provided on both sides of the mounting groove 21. The auxiliary grooves 22 are connected to the mounting groove 21 and are located in the mounting groove 21 directly opposite the bolt hole 41. The end of the fastening bolt can enter the auxiliary groove 22 to press against the elastic plate 31.

[0039] With the above-described configuration, the auxiliary groove 22 provides space for the end of the fastening bolt to extend, allowing the bolt end to penetrate deep into the mounting groove 21 and contact the elastic plate 31, rather than merely pressing against the opening edge of the mounting groove 21. This increases the contact area between the bolt and the elastic plate 31, resulting in a more secure clamping fixation. In this embodiment, the auxiliary groove 22 is a strip-shaped groove parallel to the mounting groove 21 and symmetrically arranged on both sides of the mounting groove 21. This configuration makes the process of creating the auxiliary groove 22 more convenient and simple. In other embodiments, the auxiliary groove 22 can also be configured as a groove of other shapes, such as a circular or square groove adapted to the end of the fastening bolt.

[0040] Further, refer to Figure 4 The limiting protrusion 32 is a vertically arranged arc-shaped plate, and the side of the arc-shaped plate opposite to the rotating shaft 2 is an arc-shaped surface.

[0041] When the elastic limiting member 3 is not directly aligned with the limiting groove 11, and the elastic limiting member 3 and the rotating shaft 2 enter the shaft hole, the limiting protrusion 32 has a guiding arc-shaped surface, and the inner wall of the shaft hole presses against the limiting protrusion 32, making the deformation process of the elastic plate 31 smoother. When the elastic limiting member 3 enters the limiting groove 11, since the arc-shaped plate is vertical, the vertical plate exhibits good overall rigidity when transmitting torque, and can withstand the torque when the rotating member 1 rotates, thus ensuring a stable limiting effect.

[0042] In this embodiment, the arc shape of the curved surface only serves to guide the elastic limiting member 3 and the rotating shaft 2 when they enter the shaft hole, reducing processing costs to achieve the most basic and necessary guiding function. In other embodiments, the arc shape of the curved surface can also be made into a circular arc transition surface in the horizontal direction, so that it can also serve as a guide when the elastic limiting member 3 enters the limiting groove 11.

[0043] When the elastic plate 31 and the limiting protrusion 32 enter the limiting groove 11 and transmit the rotational torque of the rotating shaft 2 to the rotating member 1, due to the elongated design of the elastic plate 31, the upper end of the elastic plate 31 may detach from the mounting groove 21 and completely enter the limiting groove 11, thereby losing the pressing effect of the inner wall of the mounting groove 21. This may cause the upper part of the elastic plate 31 to deform and bend in the tangential direction of rotation. To avoid this situation, further reference is made to... Figure 4 The upper end of the rotating shaft 2 is provided with a clearance groove 23, and the clearance groove 23 is connected to the upper end of the mounting groove 21. The upper end of the elastic plate 31 is provided with a horizontal upper limit edge 312, which can enter the clearance groove 23 and abut against the bottom surface of the clearance groove 23.

[0044] By setting the upper limit edge 312, when the upper end of the elastic plate 31 disengages from the mounting groove 21 and fully enters the limiting groove 11, the upper limit edge 312 can still remain in the clearance groove 23 located on the rotating shaft 2 or in the connection between the clearance groove 23 and the mounting groove 21. The upper limit edge 312 is still pressed by the inner sidewall of the clearance groove 23 and the mounting groove 21, which avoids the upper part of the elastic plate 31 from deforming and bending in the tangential direction of rotation, and maintains the stability and working life of the elastic limiting member 3 as a whole when transmitting torque.

[0045] Further, refer to Figure 5 A turntable bushing 5 is fixedly and coaxially arranged on the lower side of the center of the rotating part 1. The rotating shaft 2 is simultaneously movably sleeved in the shaft hole and the turntable bushing 5. The limiting groove 11 extends on the inner side wall of the turntable bushing 5.

[0046] Through the above settings, the turntable bushing 5 extends the mating length between the rotating shaft 2 and the rotating component 1, thereby increasing the force-bearing support area of ​​the rotating component 1, enabling it to withstand greater torque and improving transmission reliability.

[0047] Further, refer to Figure 2 The drive assembly also includes a bearing 6, which is located below the turntable sleeve 5. The rotating shaft 2 is simultaneously movably sleeved in the shaft hole, the turntable sleeve 5 and the bearing 6. The upper and lower ends of the limiting groove 11 are open. The rotating shaft 2 is provided with a limiting ring 7, which abuts against the lower side of the bearing 6.

[0048] With the above settings, the limiting ring 7 can conveniently and quickly restrict the position of the bearing 6 on the rotating shaft 2 during the installation of the rotating component 1.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
