Description

Technical Field

[0001] This utility model relates to the field of industrial embroidery technology, specifically to a non-standard embroidery bead feeding device and an embroidery machine. Background Technology

[0002] Currently, the most commonly used bead shapes on embroidery machines are round or rhomboid, which are symmetrical on both the top and bottom. However, for some special-shaped beads, such as those with a trapezoidal cross-section, it is necessary to distinguish their direction when embroidering them onto the fabric. The existing bead cutting device cannot distinguish the direction of the beads for cutting. Therefore, the embroidery of such irregularly shaped beads can usually only be done by hand, which greatly reduces the production efficiency of enterprises and increases their production costs. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a non-standard bead cutting device and an embroidery machine. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0004] A device for feeding irregularly shaped embroidered beads includes a material cup and a feeding tube. One end of the feeding tube is connected to the inner cavity of the material cup, and the other end is connected to a bead guide plate at the lower end of an embroidery machine. A turntable is provided at the bottom of the material cup, and several guide grooves are arranged circumferentially on the inner side of the lower end of the material cup. The cross-sectional shape of the guide grooves is adapted to the longitudinal section shape when the irregularly shaped embroidered beads are fed in the correct direction. The direction of the irregularly shaped embroidered beads in the material cup is adjusted by rotating the turntable, and the irregularly shaped embroidered beads in the correct direction are fed into the feeding tube through the guide grooves, and then fall onto the bead guide plate through the feeding tube.

[0005] Furthermore, the material cup includes a base and a cup body fixed on the base. The turntable is disposed on the base and can rotate relative to the cup body. The turntable includes a feeding surface located at the circumferential edge and a stirring surface located in the middle. The bottom of the cup body extends towards the center to form an annular bottom surface with a central opening. The annular bottom surface is located above the turntable and has a baffle surface opposite to the feeding surface. A baffle is provided on the inner side of the baffle surface opposite to the circumferential edge of the stirring surface. The guide groove extends laterally through the baffle and its two ends are respectively connected to the inner cavity of the material cup and the feeding channel formed by the baffle surface and the feeding surface. The feeding channel is connected to one end of the discharge pipe and can only accommodate one irregularly shaped bead in both the width and height directions. The irregularly shaped bead in the correct orientation in the material cup enters the feeding channel along the guide groove and then enters the discharge pipe along the feeding channel for discharge.

[0006] Furthermore, the height of the mixing surface gradually decreases from the center to the periphery.

[0007] Furthermore, the feeding surface has friction textures.

[0008] Furthermore, the turntable is provided with a groove, and a stirring rod is provided in the groove.

[0009] Furthermore, the stirring rod is composed of at least two magnets that attract each other from bottom to top, with one magnet located inside the groove and the remaining magnets stacked sequentially at the upper end of the groove.

[0010] Furthermore, the height of the cross-section of the feed tube is adapted to the thickness of the irregular embroidered bead, and the length of the longest side of the upper and lower sides of the cross-section of the cavity is adapted to the length of the longest side of the upper and lower sides of the longitudinal section of the irregular embroidered bead, so that the feed tube can accommodate only one irregular embroidered bead in both the transverse and vertical directions, and the irregular embroidered bead can pass through the feed tube in sequence in a set direction and fall into the bead guide plate.

[0011] Furthermore, the feeding tube includes a first rigid connecting part, a second rigid connecting part, and a flexible connecting part connecting the first rigid connecting part and the second rigid connecting part located at both ends. The first rigid connecting part is disposed on the base and communicates with the feeding channel. The lower end of the second rigid connecting part is fixed to the upper end of the guide bead plate, and the lower end of the second rigid connecting part is provided with a discharge port, which is opposite to the drop port provided on the guide bead plate.

[0012] Furthermore, it also includes an electrical control device and a sensor. The sensor is located at one end of the feed tube near the material cup. When the irregularly shaped beads in the feed tube accumulate to a certain number, the electrical control device controls the turntable to stop rotating.

[0013] This utility model also discloses an embroidery machine, including the aforementioned irregular embroidery bead feeding device.

[0014] The beneficial effects of this utility model are:

[0015] 1. A rotatable turntable flips irregularly shaped beads, adjusting their orientation during the flipping process. The beads are then fed into a feeding channel via a guide trough whose cross-sectional shape matches the correct orientation of the beads, thus adjusting their feeding direction. A feeding pipe, connected to the feeding channel and with a cross-sectional shape matching the cross-sectional shape of the beads as they fall onto the guide plate, then delivers the adjusted beads onto the guide plate. This feeding process prevents beads from falling or getting stuck, ensuring feeding efficiency. The beads on the guide plate are then quickly fed through a feeding plate and work with the embroidery needle for rapid embroidery, reducing production costs and increasing efficiency.

[0016] 2. By dividing the working surface of the turntable into a feeding surface and a stirring surface, and separating the feeding surface and the stirring surface with a baffle, irregularly shaped embroidered beads with the correct orientation and those with the incorrect orientation will not be confused during the feeding process, thus ensuring the accuracy of bead feeding during the unloading process.

[0017] 3. By controlling the dimensions of the guide trough and feeding channel, irregularly shaped beads can be fed in an orderly manner without causing bead jamming.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-9This utility model embodiment provides a non-standard embroidered bead feeding device, specifically including a material cup 1 and a feeding tube 2. One end of the feeding tube 2 is connected to the inner cavity of the material cup 1, and the other end is connected to the bead guide plate 3 at the lower end of the embroidery machine. A turntable 4 is provided at the bottom of the material cup 1, and several guide grooves 5 are arranged circumferentially on the inner side of the lower end of the material cup 1. The cross-sectional shape of the guide groove 5 is adapted to the longitudinal section shape when the non-standard embroidered bead is fed in the correct direction, that is, the cross-sectional shape of the guide groove 5 is the same as the longitudinal section shape when the non-standard embroidered bead is fed in the correct direction, and is slightly larger than the longitudinal section size of the non-standard embroidered bead, so that only one non-standard embroidered bead in the correct direction can pass through. The direction of the non-standard embroidered bead in the material cup 1 is adjusted by rotating the turntable 4, and the non-standard embroidered bead in the correct direction is fed into the feeding tube 2 through the guide groove 5, and then falls onto the bead guide plate 3 through the outlet 2-4 at the lower end of the feeding tube 2.

[0030] By setting a rotatable turntable to flip the irregularly shaped embroidery beads, the direction of the irregularly shaped embroidery beads is adjusted during the flipping process. The irregularly shaped embroidery beads with the correct orientation are then fed out through the guide groove 5, whose cross-section matches the longitudinal section shape when the irregularly shaped embroidery beads are cut in the correct orientation. This achieves the adjustment of the cutting direction of the irregularly shaped embroidery beads. Then, they are fed out through the corresponding feeding pipe 2 to the bead guide plate 3, and then into the jaws of the bead feeding plate 6. Finally, the bead feeding plate 6 provides rapid feeding, and in conjunction with the embroidery needle, rapid bead embroidery is achieved, which reduces the production cost of enterprises and increases production efficiency.

[0031] Further, the cup 1 includes a base 1-1 and a cup body 1-2 fixed on the base 1-1. The turntable 4 is disposed on the base 1-1 and can rotate relative to the cup body 1-2. The turntable 4 includes a feeding surface 4-1 located at the circumferential edge and a stirring surface 4-2 located in the middle. The bottom of the cup body 1-2 extends towards the center of the base 1-1 to form an annular bottom surface 1-2-1 with a central opening. The annular bottom surface 1-2-1 is located above the turntable 4 and has a baffle surface 1-2-2 disposed opposite to the feeding surface 4-1. A baffle 1-2-3 is provided at the bottom of the annular bottom surface 1-2-1 inside the baffle surface 1-2-2, which is opposite to the circumferential edge of the mixing surface 4-2. The guide groove 5 extends horizontally through the baffle 1-2-3, and its two ends are respectively connected to the inner cavity of the material cup 1 and the feeding channel formed by the baffle surface 1-2-2 and the feeding surface 4-1. The feeding channel is connected to one end of the discharge pipe 2. The irregularly shaped beads in the correct orientation in the material cup 1 can enter the feeding channel along the guide groove 5 and enter the discharge pipe 2 along the feeding channel.

[0032] Furthermore, a drive motor 7 is fixed to the bottom of the base 1-1. The motor shaft of the drive motor 7 passes through the base 1-1 and is fixed to the middle of the turntable 4. When the drive motor 7 is working, the motor shaft drives the turntable 4 to rotate relative to the cup body 1-2.

[0033] The turntable 4 is divided into two parts: one for feeding and the other for stirring. The stirring surface 4-2 is used to stir the irregularly shaped beads, causing them to change direction. The irregularly shaped beads with the correct orientation enter the feeding surface 4-1 through the guide groove 5. A baffle 1-2-3 is set on the annular bottom surface 1-2-1 to isolate the feeding surface 4-1 from the stirring surface 4-2, preventing the beads being fed from being mixed with the beads being stirred. At the same time, the distance between the feeding surface 4-1 and the baffle surface 1-2-2, i.e., the height of the feeding channel, is slightly higher than the height of the irregularly shaped beads. That is, the height of one irregularly shaped bead < the height of the feeding channel < the sum of the heights of two irregularly shaped beads stacked together. This ensures that the feeding channel can only accommodate one bead in the height direction, while also ensuring that the bead does not flip in the feeding channel and always maintains the correct orientation.

[0034] In addition, the width of the feeding channel is slightly larger than the maximum width of the irregular embroidery beads, that is, the maximum width of one irregular embroidery bead < the width of the feeding channel < the sum of the maximum widths of two irregular embroidery beads side by side, so that the feeding channel can only accommodate one embroidery bead in the width direction, and the irregular embroidery beads can fall into the feeding tube 2 in sequence without jamming.

[0035] Furthermore, in order to improve the conveying efficiency of irregular embroidered beads, the height of the stirring surface 4-2 is designed to gradually decrease from the center to the periphery, that is, the stirring surface 4-2 is set in a frustum shape. In this way, the irregular embroidered beads always move towards the side closer to the guide groove 5 during rotation, so that the irregular embroidered beads with the correct orientation can quickly enter the guide groove 5.

[0036] Furthermore, in order to improve the conveying efficiency of irregularly shaped beads, the feeding surface 4-1 has friction texture, thereby increasing the friction between the beads and the feeding surface 4-1, preventing them from slipping in the feeding channel and failing to enter the discharge pipe 2 smoothly.

[0037] Furthermore, a groove 4-3 is provided inside the turntable 4, and a stirring rod (not shown in the figure) is provided inside the groove 4-3. The stirring rod is located near the baffle 1-2-3. The rotation of the turntable 4 drives the stirring rod to rotate, thereby stirring the irregular embroidery beads inside the turntable 4, which speeds up the tumbling speed of the irregular embroidery beads. At the same time, irregular embroidery beads that are not oriented correctly near the guide chute 5 will also be carried away by the stirring rod, thereby speeding up the discharge speed.

[0038] Preferably, the stirring rod is composed of at least two magnets attracting each other from bottom to top. One magnet is located inside the groove 4-3, and the remaining magnets are stacked sequentially at the upper end of the groove 4-3. In this embodiment of the invention, the stirring rod is composed of two attracting magnets. One magnet is located inside the groove 4-3 and is flush with the upper surface of the groove 4-3, while the other magnet is located at the upper end of the groove 4-3. When the irregularly shaped bead touches the magnet, the upper magnet can be offset to a certain extent with the movement direction of the irregularly shaped bead, thereby playing a buffering role and avoiding a hard collision with the bead, which could damage the bead.

[0039] Furthermore, the height H of the cavity cross-section of the feed tube 2 is adapted to the thickness of the irregular embroidered bead, and the length L of the longest side of the upper and lower sides of the cavity cross-section is adapted to the length of the longest side of the upper and lower sides of the longitudinal section of the irregular embroidered bead. That is, the height of the cavity cross-section of the feed tube 2 is slightly greater than the thickness of the irregular embroidered bead, and the length of the longest side of the upper and lower sides of the cavity cross-section is slightly greater than the length of the longest side of the upper and lower sides of the longitudinal section of the irregular embroidered bead, so that the feed tube can accommodate only one irregular embroidered bead in both the transverse and vertical directions. The irregular embroidered bead can pass through the feed tube in sequence in a set direction and fall onto the bead guide plate 3.

[0040] During the feeding process through this feeding tube, there will be no problem with the embroidered beads falling off or getting stuck, thus ensuring feeding efficiency and further improving the company's production efficiency. Moreover, the irregular embroidered beads falling into the guide plate are in the correct direction, ensuring the accuracy of feeding.

[0041] Furthermore, the feeding tube 2 includes a first rigid connecting part 2-1, a second rigid connecting part 2-2, and a flexible connecting part 2-3 connecting the first rigid connecting part 2-1 and the second rigid connecting part 2-2 at both ends. The first rigid connecting part 2-1 is disposed on the base 1-1 and communicates with the feeding channel. The lower end of the second rigid connecting part 2-2 is fixed to the upper surface of the bead guide plate 3. The lower end of the second rigid connecting part 2-2 is provided with a discharge port 2-4. The discharge port is opposite to the drop port provided on the bead guide plate 3. The irregular embroidered beads coming out of the discharge port 2-4 can fall directly into the jaws of the bead feeding plate through the drop port, and then be fed quickly by the bead feeding plate 6. Figure 9 The diagram shows a cross-sectional view of the cavity of the first rigid connecting part 2-1. The cross-sectional shapes of the cavities of the second rigid connecting part 2-2 and the flexible connecting part 2-3 are the same as those of the first rigid connecting part 2-1.

[0042] The two ends of the feed pipe 2 are made into rigid connectors to ensure the stability of feeding and discharging. The middle part can be made into a soft and smooth flexible component to facilitate the connection of the two rigid connectors.

[0043] Furthermore, one end of the first rigid connecting part 2-1 is horizontally fixed to the base 1-1 and communicates with the feeding channel, and the other end is bent downward and connected to one end of the flexible connecting part 2-3; one end of the second rigid connecting part 2-2 is horizontally fixed to the guide bead plate 3, and the other end is bent upward and connected to the other end of the flexible connecting part 2-3.

[0044] By bending the opposite ends of the first and second rigid connecting parts that do not deform, the flexible connecting part in the middle that is easily deformed becomes a smooth pipe, which will not deform at the connection with the first and second rigid connecting parts, thus not affecting the discharge efficiency.

[0045] In addition, the portion of the first rigid connection part 2-1 of the feed tube 2 opposite to the base 1-1 can have a complete cavity, or it can form a cavity together with the supporting base 1-1 and / or the feeding surface 4-1.

[0046] In addition, the guide chute 5 is not installed on some of the baffles near the feed pipe 2 to ensure that the irregular embroidered beads can enter the feed pipe 2 in sequence and will not accumulate at the feed pipe 2.

[0047] Furthermore, the feeding device also includes an electrical control device and a sensor (not shown in the figure). The sensor is located at the end of the feeding tube 2 near the material cup 1, and the sensor can be a photoelectric sensor. When the irregularly shaped embroidered beads in the feeding tube 2 accumulate to a certain quantity, the electrical control device controls the drive motor 7 to stop working, thereby controlling the turntable 4 to stop rotating; when the number of irregularly shaped embroidered beads in the feeding tube 2 decreases to a set value, the electrical control device controls the drive motor 7 to restart. Specifically, the electrical control device determines the amount of reduction of irregularly shaped embroidered beads based on the number of times the bead feeding plate 6 it controls feeds beads, thereby controlling the operation of the drive motor 7.

[0048] This utility model embodiment also discloses an embroidery machine, which includes the above-described irregular embroidery bead feeding device.

[0049] The working process of this irregular bead cutting device is as follows:

[0050] When feeding is required, the drive motor 7 is controlled by the electrical control device to start the rotation of the turntable 4. The magnet starts to stir the irregular embroidery beads in the material cup 1. The irregular embroidery beads in the correct orientation enter the feeding channel along the guide groove 5, fall onto the guide plate 3 through the feeding pipe 2, and then fall into the jaws of the feeding plate 6. When the sensor detects that the irregular embroidery beads in the feeding pipe 2 have accumulated to a certain number, the electrical control device controls the drive motor 7 to stop working, thereby controlling the turntable 4 to stop rotating. When the number of irregular embroidery beads in the feeding pipe 2 decreases to the set value, the electrical control device controls the drive motor 7 to restart, driving the turntable 4 to rotate.

[0051] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the protection scope of the present invention.
