Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a four-bead feeding device. Background Art

[0002] The embroidery machine includes a machine base, a beam and a machine head. In order to improve work efficiency, a plurality of machine heads are generally arranged side by side on the beam. The more machine heads are arranged, the higher the efficiency is, and the smaller the spacing between the machine heads is. A bead feeding device needs to be set on the machine head used for bead embroidery for feeding beads, and the bead feeding device includes a bead feeding mechanism, a bead feeding drive mechanism and other necessary mechanisms, which need to occupy a large space. However, the distance between the machine heads is small, and it is difficult to install and accommodate a larger bead feeding device. Therefore, it is urgent to reduce the space of the bead feeding device on the machine head, especially the horizontal space should be reduced as much as possible, so that the bead feeding device can be easily installed and used in the case of machine heads with small spacing.

[0003] The existing four-bead feeding device has to feed four beads, has a complex structure, and occupies a lot of space. In order to facilitate installation and use, it is necessary to reasonably install various mechanisms and components. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with specific embodiments.

[0031] refer to Figure 1-11 A four-bead feeding device comprises first to fourth groups of bead feeding mechanisms 1 for feeding beads to the same needle 5.

[0032] The first group of bead feeding mechanisms includes a corresponding first bead feeding mechanism 101, a corresponding first bead feeding driving mechanism 201, a first motor mounting plate and a corresponding first motor 801;

[0033] The second set of bead feeding mechanisms includes a corresponding second bead feeding mechanism 102, a corresponding second bead feeding driving mechanism 202, a second motor mounting plate and a corresponding second motor 802;

[0034] The third group of bead feeding mechanisms includes a corresponding third bead feeding mechanism 103, a corresponding third bead feeding driving mechanism 203, a third motor mounting plate and a corresponding third motor 803;

[0035] The fourth group of bead feeding mechanisms includes a corresponding fourth bead feeding mechanism 104, a corresponding fourth bead feeding driving mechanism 204, a fourth motor mounting plate and a corresponding fourth motor 804;

[0036] The fourth motor 804 is installed on the fourth motor plate, the fourth motor 804 is arranged toward the inner side of the machine head and is arranged in the distance between two adjacent machine heads 7, the third motor 803 is installed on the third motor plate and is arranged toward the outer side of the machine head, and the second motor mounting plate, or the first motor mounting plate and the second motor mounting plate are provided with a recess 6 for accommodating the third motor 803 at a position corresponding to the third motor.

[0037] The first motor 801 and the second motor 802 can be arranged in an interlaced manner up and down as required. And they are installed on the corresponding motor mounting plate, which can further optimize the overall structure. According to the attached figure, the first motor 801 is arranged at the upper end, and the second motor 802 is arranged at the lower end. The two are arranged up and down and arranged in an interlaced manner, which only increases the longitudinal extension space and occupies little lateral space.

[0038] The fourth motor 804 is arranged in the interval between two adjacent machine heads 7 and is arranged toward the inside of the machine heads to free up installation space on the other side for the third motor 803. The first and second bead feeding drive mechanisms are installed obliquely to free up space for the third motor 803. An avoidance recess 6 is provided to accommodate the third motor 803. The position setting is reasonable, space is saved, and the structure is compact.

[0039] like Figure 6 The lower end of the bead feeding mechanism 1 is provided with a bead feeding groove 3 for the bead feeding mechanism 1 to slide, and the angle α between the central axes of the bead feeding grooves 3 corresponding to two adjacent bead feeding mechanisms 1 is 20~22 degrees, for example, 20.8 degrees, 21.2 degrees, 21.6 degrees, etc.

[0040] Preferably, the angle α between the central axes of the bead feeding grooves 3 corresponding to the two adjacent bead feeding mechanisms 1 is 21 degrees. This angle can not only reasonably install each bead feeding mechanism, but also minimize the space occupied by each bead feeding mechanism, especially the horizontal space between the two heads. The "horizontal" means the direction of installation toward the head.

[0041] It also includes a bead feeding bottom plate 4, and the bead feeding bottom plate 4 includes a first bead feeding bottom plate 401 and a second bead feeding bottom plate 402. The first bead feeding bottom plate 401 is provided with a first bead feeding groove 301 corresponding to the first bead feeding mechanism 101, and a second bead feeding groove 302 corresponding to the second bead feeding mechanism 102. The second bead feeding bottom plate 402 is provided with a third bead feeding groove 303 corresponding to the third bead feeding mechanism 103, and a fourth bead feeding groove 304 corresponding to the fourth bead feeding mechanism 104. The two bead feeding grooves are arranged on the same bottom plate, and there is no need to set up a separate bottom plate for combined installation. In this way, the matching accuracy is high, the error is small, and the cost is low. There will be no gap between two adjacent bead feeding structures, and it will not affect the position of the bead feeding mechanism to deliver beads, and the beads are delivered more accurately.

[0042] The bead feeding mechanism 1 and the bead feeding driving mechanism can both adopt existing technologies. The bead feeding mechanism 1 includes a bead feeding clamp for sliding bead feeding, a bead clamp driving block for driving the bead feeding clamp to clamp and release beads, and a bead guide block arranged above the bead feeding clamp's bead clamping position. The bead clamp driving block drives the bead feeding clamp to slide to clamp beads or slide to release beads, and the bead guide block is provided with a bead guide hole for guiding beads. The bead feeding driving mechanism includes a driving motor and a driving arm, one end of the driving arm is connected to the output shaft of the driving motor, and the other end is connected to a driving cam, and the driving cam is arranged on a slider for driving the bead feeding clamp to slide. The driving motor drives the driving arm to swing, and the driving arm drives the slider to slide, and further drives the bead feeding clamp to slide on the bead feeding groove.

[0043] In the utility model, the inner side is the side where the head is located on the machine body when the embroidery machine is working normally, and the side where the head faces away from the machine body (i.e. the front of the head, facing the operator) is the outer side.

[0044] The utility model provides a four-bead feeding device, four bead feeding mechanisms and a bead feeding driving mechanism are reasonably arranged, compact in structure, easy to install, and occupy a small lateral space, thus meeting the installation requirement of a small head spacing.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
