Description

Technical Field

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

[0002] The multi-bead feeding device can be used to feed multi-color beads. The existing multi-color beads usually include a bead guide rod for multi-channel bead feeding, a bead feeding clamp mechanism, and a bead switching mechanism arranged above the bead feeding clamp. Each bead guide rod places a corresponding bead into the bead hole waiting for bead feeding. The bead switching mechanism switches the corresponding row of bead guide holes on the block according to the needs of embroidery beads and transfers them to the bead feeding station of the bead feeding clamp. The bead feeding clamp receives the corresponding beads from the bead feeding station for bead feeding.

[0003] In the prior art, a plurality of bead guide holes arranged transversely and front to back are provided on the bead guide block, and a switching mechanism is used to drive the bead guide block to move transversely. If the bead guide holes arranged front to back on the bead guide block need to correspond to the bead feeding position, it is usually necessary to move the bead feeding clamp to change the bead receiving position of the bead feeding clamp. The driving mechanism of the bead feeding clamp needs to adjust the driving distance at any time, and repeatedly change the data of the driving motor to adapt to the bead guide holes in different positions. This is not only easy to produce errors, making it difficult to receive beads, but also more troublesome to operate, increasing the load on the motor. Moreover, this method cannot guarantee that the bead feeding clamp will open the clamping mouth to clamp the beads when it moves to the lower end of the bead guide hole. Utility Model Content

[0004] In order to solve the above problems of the prior art, the utility model provides a multi-bead feeding device, in which a slider corresponding to the corresponding bead guide hole is arranged at the rear end of the bead feeding clamp, so that the bead feeding clamp is opened in the bead clamping position, which reduces the motor load and is simple to operate.

[0005] The technical solutions adopted are as follows:

[0006] A multi-bead feeding device comprises a bead guide rod for supplying a corresponding number of beads, a bead feeding mechanism, a mounting frame, a bead guide block arranged above the bead feeding mechanism, and a switching mechanism for driving the bead guide block to move beads of any path into the bead feeding position. The bead feeding mechanism comprises a bottom plate, a bead feeding clamp sliding on the bottom plate, and a bead clamp driving structure for driving the bead feeding clamp to advance and retreat. The bead guide block is provided with at least two horizontal rows of bead guide holes arranged front and back, and each horizontal row is provided with at least one bead guide hole. One side of the bottom plate is provided with a corresponding slider which can move to the rear end of the bead feeding clamp to block the bead feeding clamp from retreating, open the clamping mouth of the bead clamp and cooperate with the bead guide holes of the corresponding horizontal row, and a slider driving structure for driving the slider to move. The bead guide holes in the same horizontal row correspond to the same slider; the corresponding slider is a corresponding row slider that cooperates with the horizontal row bead guide holes arranged one-to-one in the front and back; or is a corresponding row slider that cooperates with the horizontal row bead guide holes corresponding one-to-one from the second row to the last row from front to back.

[0007] Furthermore, the switching mechanism includes a switching block connected to the guide bead block and a driver for driving the switching block to move laterally.

[0008] Furthermore, the slider driving structure may be an independent driver; or the slider driving structure may be a driver provided by a switching mechanism, and the slider may be provided on a switching block.

[0009] Furthermore, the lengths of the sliders corresponding to different bead guide holes extending toward the rear end of the bead feeding clamp are different, and the extension lengths of the sliders corresponding to the bead guide holes close to the rear row are successively smaller than the extension lengths of the sliders corresponding to the adjacent previous row of bead guide holes.

[0010] Furthermore, a baffle which slides in linkage with the bead feeding clamp is provided above the bead feeding clamp.

[0011] Furthermore, the bead clamp driving structure includes a driving member for driving the bead feeding clamp forward or backward, a bead feeding driving motor, a driving block, a connecting rod assembly and a synchronous belt assembly arranged between the driving block and the driving motor.

[0012] Furthermore, the mounting frame is provided with a slot hole for the slider to extend to the rear end of the bead feeding clamp.

[0013] Furthermore, both sides of the bottom plate are provided with sliding grooves for the bead feeding clamp to slide, and the rear end of the sliding groove is also provided with a boss for stopping the bead feeding clamp from moving backwards.

[0014] Furthermore, the bead guide block is provided with two rows of bead guide holes arranged front and back, each row is provided with a bead guide hole, and the sliding block is provided with a bead guide hole corresponding to the rear row.

[0015] Compared with the prior art, the beneficial effects produced by the utility model are:

[0016] The utility model provides a multi-bead feeding device, wherein a bead guide block is provided at the upper end of the bead feeding mechanism, and at least two horizontal rows of bead guide holes are arranged front and back on the bead guide block, and a switching mechanism is provided on the bead guide block for driving the bead guide block to slide laterally so that the bead guide holes in the corresponding horizontal row cooperate with the clamping openings of the bead feeding clamp, and a slider that can be extended or detached to the rear end of the bead feeding clamp is provided on one side of the bottom plate for the bead feeding clamp to slide, and the slider blocks the bead feeding clamp from retreating so that the clamping openings of the bead feeding clamp open at the bead clamping position corresponding to the bead guide holes in the corresponding horizontal row, so as to clamp the beads accurately. Multiple sliders can be provided, with different lengths, and can also be driven by a driver provided by the switching mechanism. The driver drives the bead guide block and the slider to move at the same time, which saves the driving mechanism, reduces the power output, and simplifies the structure. The use of a slider as a mechanical method instead of an electric control method of a driving motor not only reduces errors, but also reduces the load on the motor, and is more convenient to operate.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments.

[0023] refer to Figure 1-4 A multi-bead feeding device includes a bead guide rod for supplying a corresponding number of beads, a bead feeding mechanism 1, a mounting frame 12, a bead guide block 2 arranged above the bead feeding mechanism, and a switching mechanism 3 for driving the bead guide block 2 to move beads of any path into the bead feeding position. The bead feeding mechanism 1 includes a bottom plate 101, a bead feeding clamp 102 sliding on the bottom plate, and a bead clamp driving structure 6 for driving the bead feeding clamp 102 to move forward and backward. The bead guide block 2 is provided with at least two rows of bead guide holes 5 arranged front and back, and each row is provided with at least one bead guide hole 5. One side of the bottom plate 101 is provided with a corresponding slider 4 that can move to the rear end of the bead feeding clamp 102 to block the bead feeding clamp 102 from retreating, so that the clamping mouth 10 of the bead clamp is opened and cooperates with the bead guide holes 5 of the corresponding row, and a slider driving structure for driving the slider to move. The bead guide holes 5 in the same row correspond to the same slider 4.

[0024] The corresponding sliders 4 are the corresponding rows of sliders 4 that match the corresponding rows of bead guide holes 5 arranged front and back, that is, the number of rows of bead guide holes 5 corresponds to the number of sliders 4. Usually, the bottom plate 101 is provided with a stopper at the bottom end where the bead feeding clamp 102 slides, so the bead guide holes 5 in the front row may not be provided with corresponding sliders 4. Therefore, the corresponding sliders 4 are the corresponding rows of sliders 4 that match the corresponding rows of bead guide holes 5 from the second row to the last row from the front to the back, that is, the number of sliders 4 is one less than the number of rows of bead guide holes 5, and the sliders 4 correspond to each other from the second row of bead guide holes 5 to the last row.

[0025] The mounting frame 12 is used to mount the driving motors provided on the bead feeding mechanism 1 and the switching mechanism 3. The mounting frame 12 is also connected to the bottom plate 101 at the lower end of the bead feeding mechanism 1.

[0026] Preferably, the bead guide block 2 is provided with two bead guide holes 5 which are arranged alternately front and back.

[0027] The bead guide hole 5 is matched with a corresponding bead guide rod (not shown in the figure), and each bead guide hole 5 is matched with a corresponding bead guide rod to guide the beads on the bead guide rod. The bead guide rod can adopt the existing technology. A bead passing baffle 8 that slides in conjunction with the bead feeding clamp 102 is provided above the bead feeding clamp 102. The baffle 8 is located on one side of the bead feeding clamp and is provided with a protruding plate 801 that protrudes forward to stop the bead guide hole 5 in the non-working position. The baffle 8 is mainly used to stop the bead guide hole 5 that has not entered the bead feeding position to prevent the beads in the bead guide hole that has not entered the bead feeding position from falling.

[0028] The bead clamp driving structure 6 can adopt the existing technology. The bead clamp driving structure 6 includes a driving member (not shown in the figure) for driving the bead feeding clamp forward or backward, a bead feeding driving motor 601, a driving block 602, a connecting rod assembly 603 and a synchronous belt assembly 604 arranged between the driving block and the driving motor. The bead clamp driving structure 6 drives the driving block 602 to move forward or backward, and the driving member is arranged on the driving block 602, and the driving block 602 can drive the driving member forward and backward.

[0029] The bottom plate 101 is provided with a slide groove 11 on both sides for the bead feeding clamp 102 to slide, and a boss 9 is also provided at the rear end of the slide groove 11 to stop the bead feeding clamp 102 from moving backward. When the bead feeding clamp 102 moves to the boss 9, the boss 9 will stop the bead feeding clamp 102 from retreating, and the driving member driving the bead feeding clamp 102 continues to retreat under the drive of the driving block 602. Since the bead feeding clamp 102 and the driving member are installed in coordination with each other, the driving member will generate a pulling force on the bead feeding clamp 102 at this time, so that the clamping opening 10 of the bead feeding clamp 102 opens. The bead feeding clamp 102 is in a bead clamping state.

[0030] Similarly, the slider 4 is disposed at the rear end of the bead feeding clamp 102, which will also prevent the bead feeding clamp 102 from retreating, so that the bead feeding clamp 102 opens the clamping opening 10 to clamp the beads.

[0031] Since the bead guide holes 5 are arranged front to back, the bead clamping positions of the bead feeding clamp 102 corresponding to different bead guide holes 5 are also different. It is necessary to set the extended position of the slider 4 according to different bead guide holes 5 so that the bead feeding clamp 102 moves to the corresponding bead guide hole 5 where the clamping mouth 10 is in an open state.

[0032] The bead feeding clamp 102 generally retreats from the bead embroidery position at the lower end of the needle to the bead clamping position at the lower end of the bead guide hole 5. Compared with the bead guide hole 5 at the rear end, the distance required for the bead feeding clamp 102 to move to the front end bead guide hole 5 is shorter, so the slider 4 corresponding to the front end bead guide hole 5 is also closer to the front.

[0033] The bead guide holes 5 in the same horizontal row correspond to the same slider 4, because the bead feeding clamp 102 moves to the lower end of the bead guide holes in the same horizontal row and needs to retreat the same distance.

[0034] The mounting frame 12 is provided with a slot 7 for the slider to extend to the rear end of the bead feeding clamp 102 .

[0035] The switching mechanism 3 includes a switching block 301 connected to the guide bead block 5 and a driver 302 for driving the switching block 301 to move laterally. The driver 302 can completely adopt the existing technology. The slider driving structure can be the driver 302, or it can be set separately.

[0036] Preferably, the slider 4 is directly arranged on the switching block 301, and the switching mechanism 3 drives the switching block 301 to slide laterally, while also driving the slider 4 to enter or leave the rear end of the bead feeding clamp 102. And the length of the slider 4 is set as required. The sliders 4 corresponding to the different bead guide holes 5 extend toward the rear end of the bead feeding clamp at different lengths; usually, the extension length of the slider 4 corresponding to the bead guide holes close to the rear row is successively smaller than the extension length of the slider 4 corresponding to the bead guide holes in the adjacent front row, so as to avoid the slider 4 corresponding to the bead guide holes in the rear row interfering with the retreat position of the bead feeding clamp 102 when the front bead guide holes are in use. The slider 4 is connected to the switching block 301 through a connecting rod, and the bead guide block 2 is also connected to the switching block 301, so when the switching block 301 moves, the bead guide block 2 and the slider 4 will move simultaneously.

[0037] Since the slider 4 and the bead guide hole 5 slide laterally at the same time, the slider 4 corresponding to the front bead guide hole 5 is shorter than the rear bead guide hole 5. It is ensured that when the bead feeding clamp 102 moves to the bead clamping position of the rear bead guide hole, the slider 4 corresponding to the front bead guide hole will not prevent the bead feeding clamp 102 from retreating.

[0038] The utility model does not need to adjust the retreat distance of the driving member on the bead feeding mechanism 1 according to the position of the bead guide hole 5 at all times. The boss 9 and the slider 4 are arranged on the bottom plate 101 to ensure that the bead feeding clamp is in an open state at a specific position. The preferred switching mechanism also drives the bead guide block and the slider to slide laterally at the same time, making the structure simpler and reducing the driving load.

[0039] Referring to the attached drawings, as a simple implementation example, the bead guide block 2 is provided with two horizontal rows of bead guide holes 5 arranged front and back, each horizontal row is provided with a bead guide hole 5, and the slider 4 is provided with one, corresponding to the bead guide hole 5 close to the rear row.

[0040] For the convenience of expression, this application uses directional words such as front, back, and transverse, which are only a custom setting in the field and are not used as a limitation on the protection concept of this application. Among them, when the multi-bead feeding device is normally installed up and down, the direction of the bead clamp moving toward the needle direction to feed the beads is the front, the direction of retreating from the needle station to receive the beads is the rear, the horizontal direction perpendicular to the front and back direction is the transverse direction, and the transversely arranged bead guide holes are the horizontal rows.
