Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to a sequined belt reel and an embroidery machine. Background Technology

[0002] Sequin embroidery, with its vibrant colors and shimmering effect, is widely popular in evening gowns, stage costumes, and other settings. Sequins are mostly flat shapes such as round, oval, square, and plum blossom, with a needle eye in the center for embroidery needles and thread to pass through. During embroidery, the needle and thread are passed through the needle eye to sew the sequins onto the fabric surface. Currently, bead embroidery is mainly mass-produced using bead embroidery machines.

[0003] When operating a bead embroidery machine, a continuous high-speed supply of sequins is required. To meet this demand, the industry typically connects the sequins one by one to form a sequin belt, and then winds the sequin belt onto a take-up reel. The take-up reel is installed on the feeding rack of the embroidery machine to achieve stable conveying of the sequins.

[0004] Existing winding reels mainly consist of two baffles, each with a winding half-roller protruding from its inner side. When the two baffles are joined together, the winding half-rollers form a winding wheel for winding sequined tape. The baffles and winding half-rollers are integrally injection-molded. Because the width of this winding wheel is fixed, it can only accommodate sequined tapes of a single width. However, in practical applications, sequins come in various shapes and diameters, such as 2mm and 10mm, requiring the development of winding reels of different specifications. This results in large space requirements, high production costs, and significant material waste. Summary of the Invention

[0005] The purpose of this utility model is to provide a sequined belt reel that improves adaptability, reduces development costs, and saves raw materials through its split structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sequined belt take-up reel includes a left limiting disc, a right limiting disc, and a take-up wheel disposed between the left limiting disc and the right limiting disc;

[0008] The winding reel includes a cylindrical winding section, and several connecting parts are fixed on the inner side of the winding section. The connecting parts include two lugs with internal threaded holes arranged along the length of the winding section. The left and right limiting discs are provided with through holes directly opposite the internal threaded holes. The left limiting disc and the lugs, and the right limiting disc and the lugs are all fixedly connected by screws.

[0009] In the above technical solution, the winding reel is configured with a left limiting plate, a right limiting plate, and a winding wheel. When winding and wrapping sequined strips with different diameter requirements, only the corresponding winding wheel needs to be replaced to achieve adaptation. There is no need to perform corresponding injection molding of the entire winding reel, which can reduce costs and facilitate use.

[0010] The take-up reel is equipped with several take-up sections of different lengths, which can be selected according to actual needs. Here, "length" refers to the length of the take-up section along the axial direction, corresponding to the diameter of the sequins in the sequin belt. For example, for 2mm sequins, the length of the take-up section can be selected as 3mm to avoid wear on the sequins and improve the smoothness of the sequin belt feeding. For 10mm sequins, the length of the take-up section can be selected as 11mm or 12mm, which can accommodate the sequins without affecting their release.

[0011] During assembly, the winding section is placed between the left and right limiting plates and connected with screws, making assembly convenient. During manufacturing, the winding reel is integrally molded, meaning the winding section and the lug are injection molded as a single piece, facilitating processing and allowing the use of any plastic material.

[0012] By replacing different take-up reels, the installation spacing of the left and right limit plates of the take-up reel can be flexibly adjusted according to the width of the sequined strip. This eliminates the need to develop multiple take-up reels for different specifications of sequined strips, effectively reducing equipment space occupation, production costs and material waste, while also simplifying the assembly and maintenance process of the take-up reel.

[0013] Preferably, a reinforcing wheel is provided on the inner side of the winding wheel, and the reinforcing wheel is fixedly connected to the winding wheel by several reinforcing rods. The left and right limiting plates are provided with clearance holes through the inner holes of the reinforcing wheel.

[0014] Preferably, both the left and right limiting discs are provided with outwardly recessed limiting portions, and the two ends of the winding wheel are respectively fixed with limiting plates that cooperate with the limiting portions of the left and right limiting discs.

[0015] Preferably, a positioning block is provided on the outer side of the limiting plate, and the limiting parts of the left and right limiting plates are provided with positioning ports that cooperate with the positioning block.

[0016] Preferably, a positioning cylinder is fixed between the winding reel and the reinforcing reel, and the limiting parts of the left and right limiting discs are both provided with positioning pins that are inserted and engaged with the positioning cylinder.

[0017] Preferably, the outer surfaces of the left and right limiting discs are fixed with reinforcing cylinders facing the outer periphery of the perforation.

[0018] As a preferred option, both the left and right limit plates are equipped with observation windows.

[0019] As a preferred option, reinforcing rings are fixedly installed on the outer sides of both the left and right limiting plates, directly opposite the observation window.

[0020] As a preferred embodiment, reinforcing plates are provided on the outer sides of the left and right limit plates.

[0021] Another objective of this invention is to provide an embroidery machine that utilizes the aforementioned sequined belt reel to improve the efficiency of bead embroidery.

[0022] To achieve another objective of this utility model, the following technical solution is adopted:

[0023] An embroidery machine includes a feeding frame and the aforementioned sequined tape take-up reel, the sequined tape take-up reel being mounted on the feeding frame. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1-6 This utility model provides a sequined tape take-up reel, including a left limiting disc 1, a right limiting disc 11, and a take-up wheel disposed between the left limiting disc 1 and the right limiting disc 11;

[0032] The take-up reel includes a cylindrical take-up section 12. Several connectors are fixed on the inner side of the take-up section 12. The connectors include two lugs 13 with internal threaded holes arranged along the length of the take-up section 12. The left limiting plate 1 and the right limiting plate 11 are provided with through holes 14 directly opposite the internal threaded holes. The left limiting plate 1 and the lugs 13, and the right limiting plate 11 and the lugs 13 are all fixedly connected by screws 15.

[0033] In the above technical solution, the winding reel is configured with a left limiting plate, a right limiting plate, and a winding wheel. When winding and wrapping sequined strips with different diameter requirements, only the corresponding winding wheel needs to be replaced to achieve adaptation. There is no need to perform corresponding injection molding of the entire winding reel, which can reduce costs and facilitate use.

[0034] The take-up reel is equipped with several take-up sections of different lengths, which can be selected according to actual needs. Here, "length" refers to the length of the take-up section along the axial direction, corresponding to the diameter of the sequins in the sequin belt. For example, for 2mm sequins, the length of the take-up section can be selected as 3mm to avoid wear on the sequins and improve the smoothness of the sequin belt feeding. For 10mm sequins, the length of the take-up section can be selected as 11mm or 12mm, which can accommodate the sequins without affecting their release.

[0035] During assembly, the winding section is placed between the left and right limiting plates and connected with screws, making assembly convenient. During manufacturing, the winding reel is integrally molded, meaning the winding section and the lug are injection molded as a single piece, facilitating processing and allowing the use of any plastic material.

[0036] By replacing different take-up reels, the installation spacing of the left and right limit plates of the take-up reel can be flexibly adjusted according to the width of the sequined strip. This eliminates the need to develop multiple take-up reels for different specifications of sequined strips, effectively reducing equipment space occupation, production costs and material waste, while also simplifying the assembly and maintenance process of the take-up reel.

[0037] During implementation, a reinforcing wheel 16 is provided on the inner side of the winding wheel. The reinforcing wheel 16 is fixedly connected to the winding wheel by several reinforcing rods 17. The left limiting plate 1 and the right limiting plate 11 are provided with clearance holes 18 through the inner hole of the reinforcing wheel 16.

[0038] In the above technical solution, by adding a reinforcing wheel to the inside of the winding wheel and fixing it with a reinforcing rod, the structural strength and rigidity of the winding wheel are significantly improved, avoiding deformation of the winding reel due to force when winding the sequin belt at high speed, ensuring the regularity of the sequin belt winding, and also ensuring the stability of the sequins when released.

[0039] The clearance holes on the left and right limit plates are aligned with the inner holes of the reinforcing wheels. When the take-up reel is installed on the feeding rack of the bead embroidery machine, the feeding rack can pass through the clearance holes and the inner holes of the reinforcing wheels, making installation convenient.

[0040] During implementation, both the left limiting plate 1 and the right limiting plate 11 are provided with outwardly recessed limiting parts 19, and the two ends of the winding wheel are respectively fixed with limiting plates 2 that cooperate with the limiting parts 19 of the left limiting plate 1 and the right limiting plate 11.

[0041] In the above technical solution, the recessed limiting parts of the left and right limiting discs cooperate with the limiting plates at both ends of the winding wheel to provide axial positioning for the winding wheel, effectively preventing axial displacement of the winding wheel during the winding process. At the same time, it increases the contact area between the winding wheel and the left and right limiting discs, thereby improving the structural reliability of the winding wheel.

[0042] During implementation, a positioning block 21 protrudes from the outer side of the limiting plate 2, and the limiting part 19 of the left limiting plate 1 and the limiting part 19 of the right limiting plate 11 are both provided with positioning ports 22 that cooperate with the positioning block 21.

[0043] In the above technical solution, the positioning block on the limiting plate and the positioning port of the limiting part cooperate with each other to form a double positioning structure, which improves the assembly accuracy of the left and right limiting plates and the winding wheel, effectively avoids circumferential misalignment during assembly, ensures that the through hole and the internal thread hole are accurately aligned when the screw is installed, simplifies the assembly operation, improves the assembly efficiency, and at the same time ensures the coaxiality of the winding wheel when it is running, reduces the vibration caused by high-speed rotation, and improves the stability of equipment operation.

[0044] During implementation, a positioning cylinder 23 is fixed between the winding wheel and the reinforcing wheel 16. The limiting part 19 of the left limiting plate 1 and the limiting part 19 of the right limiting plate 11 are both provided with positioning pins 24 that are inserted and cooperate with the positioning cylinder 23.

[0045] In the above technical solution, the positioning cylinder between the take-up reel and the reinforcing reel, and the positioning pin of the limiting part, are engaged to further enhance the connection stability and positioning accuracy between the left and right limiting discs and the take-up reel. The engagement of the positioning pin and the positioning cylinder effectively restricts the circumferential rotation of the limiting disc, preventing the screws from loosening due to vibration during the winding process. It also helps to improve the overall structural rigidity of the take-up reel, ensuring stability during high-speed rotation of the take-up reel and guaranteeing the uniformity of the sequined tape winding.

[0046] During implementation, reinforcing cylinders 25 are fixed to the outer surfaces of the left limiting plate 1 and the right limiting plate 11, facing the outer periphery of the through hole 14.

[0047] In the above technical solution, the reinforcing cylinder can enhance the structural strength of the area around the perforation, disperse the pressure generated when the screw is tightened, prevent the limit plate from cracking or deforming due to excessive screw tightening force, extend the service life of the winding reel, and at the same time ensure the firmness of the screw connection, prevent loosening after long-term use, and ensure the structural stability of the winding reel during high-speed operation.

[0048] During implementation, observation windows 26 are provided on both the left limit plate 1 and the right limit plate 11.

[0049] In the above technical solution, the observation window allows operators to observe the amount of sequined tape being wound, its winding status, and the remaining amount in real time. This allows them to monitor the sequined tape usage without disassembling the take-up reel, facilitating timely replenishment of the sequined tape and preventing the embroidery machine from stopping due to the depletion of sequined tape, thus improving production efficiency. At the same time, it allows for the timely detection and handling of abnormalities such as loose or misaligned sequined tape, reducing product defects.

[0050] During implementation, reinforcing rings 27 are fixedly installed on the outer sides of the left limit plate 1 and the right limit plate 11, directly opposite the observation window 26.

[0051] In the above technical solution, the reinforcing ring fixed on the outside of the observation window can compensate for the loss of structural strength of the limiting plate after the observation window is opened, and prevent the edge of the observation window from cracking due to stress concentration during high-speed operation or assembly of the limiting plate. The reinforcing ring not only ensures the normal use function of the observation window, but also maintains the overall structural rigidity of the limiting plate, extends the service life of the winding reel, and ensures the long-term stable operation of the equipment.

[0052] During implementation, reinforcing plates 28 are provided on the outer sides of the left limit plate 1 and the right limit plate 11.

[0053] In the above technical solution, several reinforcing plates can be provided. Specifically, a reinforcing plate can connect two adjacent reinforcing rings. The reinforcing plate can be ring-shaped and set on the inner side of the reinforcing ring, or it can be ring-shaped and set on the outer edge of the left and right limiting plates. The reinforcing plate can improve the overall structural strength and deformation resistance of the limiting plates. When the winding reel rotates at high speed or is subjected to winding tension, the reinforcing plate can effectively disperse stress, avoid bending or deformation of the limiting plates, ensure the operating accuracy of the winding reel, and enhance the limiting effect of the winding reel on the sequined belt, ensuring that the sequined belt is wound neatly and providing a guarantee for stable material supply to the embroidery machine.

[0054] Specifically, the left and right limit plates are designed with slits to hold the head of the sequined belt. The head of the sequined belt can be manually inserted into the slits to prevent it from slipping off the winding wheel.

[0055] This utility model also provides an embroidery machine, including a feeding frame and the aforementioned sequined tape take-up reel, the sequined tape take-up reel being installed on the feeding frame.

[0056] This embroidery machine has the ability to flexibly adjust to beaded ribbons of different widths, ensuring a continuous and stable supply of beaded ribbons, improving the production efficiency and product quality of the embroidery machine, and enhancing the market competitiveness of the equipment.
