Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a feeder for bead embroidery. Background Art

[0002] Bead embroidery refers to an embroidery process in which beads are fixed on fabric with an embroidery machine. In the prior art, beads are transported by a feeding mechanism, and the principle is to place the beads in a material cup and, by stirring, etc., allow the beads to pass through a vertical bead guide rod, the upper end of which is connected to the material cup.

[0003] The beads on the bead guide rod slide down along the bead guide rod under the action of gravity, and multiple clamps are arranged on the sliding path of the bead guide rod to clamp the bead guide rod. The multiple clamps are driven to open and close by a motor. When the clamps are open, the beads can pass through the clamps, and when the clamps are closed, the beads will be blocked by the clamps and cannot continue to fall.

[0004] The chuck driving mechanism in the prior art is usually arranged inside a mounting frame surrounded by mounting plates, and the chucks are arranged in sequence up and down and installed parallel to the mounting plates on both sides. The chuck driving mechanism is provided with a driving shaft, and the driving shaft is provided with driving handles corresponding to a plurality of chucks one by one. Since the driving handles need to rotate 360 ​​degrees when driven, the inner cavity of the mounting frame must be large enough to provide sufficient space for the rotation of the driving handles. This will increase the space occupied by the feeding mechanism, and the mounting frame is composed of a plurality of mounting plates, which requires more profiles.

[0005] As the density of machine heads continues to increase, the space between machine heads becomes narrower and narrower, and the existing structure of the bead embroidery feeder cannot adapt well to the multi-bead conveying device. Summary of the invention

[0006] In order to solve the above problems of the prior art, the utility model provides a bead embroidery feeder, which uses a single mounting frame to mount a chuck and a driving mechanism of the feeder, thereby saving materials and space.

[0007] The technical solutions adopted are as follows:

[0008] A bead embroidery feeder comprises a plurality of chuck assemblies for clamping a bead guide rod, a driving mechanism for driving the chucks of the chuck assemblies to open, and a mounting frame for installation, wherein the projection of the mounting frame toward the embroidery frame is provided with a first length direction and a second length direction, the first length direction and the second length direction are perpendicular to each other, the plurality of chuck assemblies are successively and obliquely installed on one side of the mounting frame along the direction of the bead guide rod, the oblique direction is a dividing line L of the chuck assembly dividing two chucks and is provided with an angle α not equal to 0° with the first length direction or the second length direction, the driving shaft of the driving mechanism is provided on the other side of the mounting frame, the driving shaft is installed close to the mounting frame, and the mounting frame is provided with a receiving groove for accommodating part of the chuck assembly or / and the driving handle at a position corresponding to the driving handle provided on the chuck assembly or / and the driving shaft.

[0009] Furthermore, the clamp assembly includes two clamps that cooperate with each other to clamp, and one of the clamps is provided with an extension arm.

[0010] Furthermore, the driving mechanism also includes a beaded barrel arranged above the mounting frame, a driving motor of the driving shaft, the barrel can be rotatably arranged relative to the mounting frame, and the upper end of the driving shaft is connected to the barrel or is provided with a driving structure for driving the barrel to rotate.

[0011] Furthermore, the driving motor is provided with a motor mounting plate for mounting the driving motor, and the mounting plate is mounted on one side of the mounting frame.

[0012] Furthermore, the drive shaft is directly connected to the motor shaft of the drive motor, or is connected to the drive motor through a synchronous belt assembly.

[0013] Furthermore, the motor mounting plate is installed on the mounting frame in the first or second length direction.

[0014] Furthermore, the upper and lower end plates of the mounting frame are provided with extension parts for mounting the drive shaft.

[0015] Furthermore, a return spring is provided between the two clamps.

[0016] Furthermore, the angle α is 15°-75°.

[0017] Furthermore, the projection of the mounting frame toward the embroidery frame is a rectangle, and the first and second length directions are corresponding adjacent sides of the rectangle.

[0018] Compared with the prior art, the beneficial effects produced by the utility model are:

[0019] The utility model provides a bead embroidery feeder, wherein a chuck assembly and a driving mechanism are arranged on the same mounting frame, and a receiving groove is arranged on the mounting frame, providing sufficient space for the chuck assembly and the driving mechanism to be installed, so as to ensure that the driving mechanism can drive the chuck jaw to open. The receiving groove can be arranged by mechanical processing, and the processing precision is high. A single mounting frame is used to replace the mounting frame composed of multiple mounting plates in the prior art, saving materials and space.

[0020] In addition, the chuck assembly is installed obliquely, which not only reduces the size of the mounting frame, but also can adapt to the relatively densely installed heads in the prior art. At the same time, the drive shaft is as close to the mounting frame as possible, further reducing the space occupied. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with specific implementation methods.

[0029] refer to Figure 1-6A bead embroidery feeder comprises a plurality of chuck assemblies 1 for clamping a bead guide rod, a driving mechanism 2 for driving the chucks of the chuck assemblies 1 to open, and a mounting frame 3 for installation. The projection of the mounting frame 3 toward the embroidery frame is provided with a first length direction and a second length direction, and the first length direction and the second length direction are perpendicular to each other. The plurality of chuck assemblies 1 are successively installed obliquely on one side of the mounting frame 3 along the direction of the bead guide rod. The oblique direction is a dividing line L of the chuck assembly that divides two chucks, and is provided with an angle α that is not 0° with the first length direction or the second length direction. The driving shaft 202 provided by the driving mechanism is provided on the other side of the mounting frame, and the driving shaft is installed close to the mounting frame 3. The mounting frame is provided with a receiving groove 4 for accommodating part of the chuck assembly 1 or / and the driving handle 204 provided on the chuck assembly or / and the driving shaft. See Figure 6 The dividing line L is usually a line that naturally divides the two chucks through the clamping openings of the two chucks.

[0030] It is best to set the receiving groove 4 to accommodate the chuck assembly 1 and the driving handle 204 to save space. The receiving groove 4 can be machined with higher processing accuracy.

[0031] The chuck assembly 1 comprises two chucks 101 that cooperate with each other to clamp, and one of the chucks is provided with an extension arm 102. The two chucks 101 are provided with teeth that mesh with each other so that the two can be rotatably connected, and the extension arm 102 is driven to move, that is, one of the two chucks 101 is driven to move, so that the two chucks are opened at the clamping mouth.

[0032] The driving mechanism 2 includes a driving motor 201 , a driving shaft 202 , and a plurality of driving handles 204 disposed on the driving shaft for driving the extension arm 102 .

[0033] The oblique direction is that the dividing line L of the chuck assembly that divides the two chucks is provided with an angle α that is not 0° with the first length direction or the second length direction, and the angle α is 15°-75°, that is, the chuck assembly 1 is installed obliquely, which is more space-saving than the chuck assembly installed parallel to the mounting plate in the prior art. The projection of the mounting frame 3 toward the embroidery frame is a rectangle, and the first and second length directions are the corresponding adjacent sides of the rectangle. The first length direction is set to be the shorter side of the rectangle, and the second length is set to be the longer side of the rectangle. If the dividing line L that divides the two chucks is installed parallel to the first length direction of the mounting frame 3, the extension arm 102 is too long and the width of the rectangular mounting frame needs to be increased; if the dividing line L that divides the two chucks is installed parallel to the second length direction of the mounting frame 3, the width of the rectangular mounting frame must be greater than or equal to the width of the two chucks (the width refers to the distance between the two farthest points on both sides of the dividing line L in the direction of the center connection line of the two chuck shafts). Both installation methods will increase the width of the mounting frame. When the chuck assembly 1 is installed obliquely, the width of the chuck just acts as the hypotenuse of a right angle of the rectangular mounting frame, forming a triangle. Since the hypotenuse of a triangle is larger than the right angle side, the oblique installation of the chuck can make the mounting frame 3 as small as possible, which not only saves materials but also saves space.

[0034] Moreover, the oblique installation of the chuck assembly 1 also makes the length of the chuck 101 extending relative to the mounting frame 3 shorter, which can occupy a smaller space. When installing multiple feeders, the installation distance can be closer, which can adapt to the more densely installed machine heads in the prior art.

[0035] The receiving groove 4 is provided to receive the chuck assembly and the driving mechanism, so that the driving shaft can be installed close to the mounting frame 3, which greatly saves space and materials, and ensures that the driving handle 204 has enough space when rotating.

[0036] The driving mechanism 2 further comprises a barrel 8 with beads arranged above the mounting frame 3, a driving motor 201 of a driving shaft 202, the barrel can be rotatably arranged relative to the mounting frame 3, and the upper end of the driving shaft 202 is connected to the barrel 8 or is provided with a driving structure for driving the barrel to rotate. The driving shaft 202 can directly drive the barrel or drive the barrel to rotate through a driving structure, and the driving structure can be a transmission gear set arranged between the barrel and the driving shaft, that is, a driving gear is arranged on the driving shaft 202, and a passive gear matched with the driving gear is arranged on the barrel 8. The barrel 8 provided with the transmission gear set is rotatably arranged on the mounting frame 3.

[0037] As an example, Figure 2 , the driving motor 201 is directly mounted on the lower end of the driving shaft 202;

[0038] As another example, Figure 1The upper end of the mounting frame 3 is provided with a motor mounting plate 6, the driving motor 201 is mounted on the lower end of the motor mounting plate 6, and the driving motor 201 is connected to the driving shaft 202 through a synchronous belt assembly 203;

[0039] As another embodiment, Figure 3 A motor mounting plate 6 is disposed at the upper end of the mounting plate 3 , and the driving motor 201 is mounted at the upper end of the motor mounting plate 6 . The driving motor 201 is connected to the driving shaft 202 via a synchronous belt assembly 203 .

[0040] In practical applications, the installation method and position of the driving motor 201 can be determined according to actual needs.

[0041] The synchronous belt assembly 203 includes a first synchronous pulley 2031 provided on the driving motor 201, a second synchronous pulley 2032 provided on the driving shaft 202, and a synchronous belt 2033 provided on the first and second synchronous pulleys. The driving motor 201 drives the first synchronous pulley 2031 to rotate, and through the transmission of the synchronous belt, the second synchronous pulley 2032 drives the driving shaft 202 to rotate. Since a plurality of driving handles 204 are provided on the driving shaft 202, the driving handles 204 can drive the extension arm 102 on the chuck assembly 1 as the driving shaft rotates, so that the chuck 101 opens at the chuck mouth.

[0042] Furthermore, a reset spring 5 is provided between the two clamps 101. When the driving handle 204 is away from the extension arm 102, the clamp 101 is reset under the driving of the reset spring 5 to clamp the guide ball rod.

[0043] The upper and lower base plates of the mounting frame 3 are provided with extension parts 7 for mounting the drive shaft.

[0044] The utility model only has one mounting frame to mount the clamping head assembly and the driving mechanism, and the clamping head assembly is installed obliquely, so the size of the mounting frame is reduced as much as possible, and materials and space are saved.

[0045] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
