Description

Technical Field

[0001] The utility model relates to the technical field of disk belt embroidery, in particular to a belt picking mechanism for disk belt embroidery. Background Art

[0002] The applicant has previously disclosed a patent. After in-depth thinking, it is found that the rope swinging mechanism is controlled by a separate motor and is in an idle state during the process of disk belt embroidery. The belt picking component can be arranged at the position where the rope swinging mechanism moves up and down to drive the belt picking component to pick the belt. Summary of the Invention

[0003] In order to solve the problems of the above-mentioned prior art, the utility model provides a belt picking mechanism for disk belt embroidery, which does not require a separate driver to pick the belt, saving costs and space.

[0004] The adopted technical solution is as follows:

[0005] A belt picking mechanism for disk belt embroidery includes a machine head, a rope swinging mechanism arranged on the machine head, a rope swinging driving mechanism, and a rope swinging transmission component capable of making a lifting motion. It further includes a first belt picking rod. A transmission arm for picking the belt is arranged on the rope swinging transmission component, which can make the first belt picking rod move along with the lifting action of the rope swinging transmission component.

[0006] The first belt picking rod can be directly arranged on the transmission arm.

[0007] The first belt picking rod can also be arranged on a first belt picking component. The first belt picking component includes a driving arm. The first belt picking rod is arranged on the driving arm. The driving arm is rotatably arranged on a fixed frame to form a lever. The fixed frame is connected to the outer shaft of a transmission shaft arranged on a material rack or the rope swinging transmission component.

[0008] Furthermore, a driving structure is arranged between the transmission arm and the driving arm.

[0009] Furthermore, the driving structure includes a convex block arranged at the upper end of the driving arm and an extension arm arranged at the lower end of the transmission arm, which can drive the convex block to make the driving arm rotate. A return spring is arranged between the convex block and the fixed frame.

[0010] Furthermore, at least one guiding shaft and / or guiding wheel for the belt is arranged on the fixed frame.

[0011] Furthermore, it further includes a second belt picking component. The second belt picking component includes a second belt picking rod and a connecting frame for installing the second belt picking rod. The connecting frame is installed and connected to a presser foot and / or a presser foot lifting sleeve.

[0012] Furthermore, rollers are arranged on the first and second belt picking rods, or the belt picking rods can be rotatably arranged.

[0013] Further, the rope pendulum transmission assembly includes a transmission shaft, a sliding sleeve that slides outside the presser foot lifting sleeve, and a sliding rod that connects the sliding sleeve and the rope pendulum mechanism.

[0014] Further, the transmission arm is arranged on the transmission shaft and / or the sliding sleeve.

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

[0016] The present utility model provides a tape picking mechanism for disk embroidery. The rope pendulum driving mechanism arranged on the disk embroidery machine head drives the rope pendulum transmission assembly to make a lifting motion, so as to drive the rope pendulum mechanism to make a rope pendulum motion. A transmission arm is arranged on the rope pendulum transmission assembly, and a first tape picking rod can be arranged on the transmission arm. When making a lifting motion along with the rope pendulum transmission assembly, the first tape picking rod can be driven to pick the tape. Or the first tape picking rod is arranged on a first tape picking rod assembly. The first tape picking rod assembly includes a driving arm and a first tape picking rod arranged on the driving arm. A driving structure is arranged between the transmission arm and the driving arm. The driving arm is rotatably arranged on a fixed frame or other mounting structures. When the rope pendulum transmission assembly makes a lifting motion, the driving arm can be driven to rotate through the transmission arm, so as to drive the first tape picking rod to perform a tape picking action.

[0017] Since the rope pendulum driving mechanism is idle during disk embroidery, it can drive the first tape picking rod to pick the tape alone. Compared with the prior art of driving through the lifting motion of the presser foot, the motion range of the first tape picking rod is determined by the lifting of the presser foot, which is limited to a certain extent. However, the separate driving method adopted by the present utility model has a larger controllable range and more precise control. At the same time, by using the idle rope pendulum driving mechanism, there is no need to separately set up a motor for driving, which not only saves space but also reduces costs.

Specific embodiments

[0028] The following further describes the present utility model in conjunction with specific embodiments.

[0029] Refer to Figures 1-9 , a tape picking mechanism for disk embroidery, comprising a machine head 1, a rope pendulum mechanism 2 provided on the machine head 1, a rope pendulum driving mechanism 3, and a rope pendulum transmission assembly 4 capable of performing lifting motion, further comprising a first tape picking rod 12. A transmission arm 6 for picking the tape is provided on the rope pendulum transmission assembly 4, and the first tape picking rod 12 can move along with the lifting action of the rope pendulum transmission assembly 4.

[0030] The rope pendulum mechanism 2, the rope pendulum driving mechanism 3, and the rope pendulum transmission assembly 4 all adopt existing technologies. The rope pendulum transmission assembly 4 includes a transmission shaft 401, a sliding sleeve 402 that slides outside the presser foot lifting sleeve, and a sliding rod 403 connecting the sliding sleeve 402 and the rope pendulum mechanism 2. The rope pendulum driving mechanism 3 includes a motor that independently drives the rope pendulum mechanism 2, and a driving component is provided between the motor and the transmission shaft for driving the transmission shaft to perform lifting motion.

[0031] The transmission arm 6 is provided on the transmission shaft 401 or / and the sliding sleeve 402. Of course, the transmission arm 6 can also be provided on the sliding rod 403, as long as it can drive the transmission arm 6 to perform lifting motion.

[0032] Embodiment 1

[0033] Refer to Figure 1 , 2 , as an embodiment, the first tape picking rod 12 can be directly provided on the transmission arm 6. The transmission arm 6 is provided on the rope pendulum transmission assembly 4. When the rope pendulum transmission assembly moves up and down, it can drive the transmission arm 6 to move up and down, that is, drive the first tape picking rod 12 to move up and down to pick the tape.

[0034] Embodiment 2

[0035] Refer to Figure 3 , 4, preferably, in order to further increase the amplitude of tape picking, the first tape picking rod 12 can be arranged on the first tape picking assembly 5. The first tape picking assembly 5 includes a driving arm 502 rotatably arranged on a fixed frame 501 to form a lever, and the first tape picking rod 12 can be arranged on the resistance arm of the driving arm 502. The fixed frame 501 is connected to the outer shaft of the material rack 10 or the transmission shaft 401 of the rope pendulum transmission assembly. The driving arm 502 can be arranged on the fixed frame 501 or on other mounting structures.

[0036] The driving arm 502 is arranged on the fixed frame 501, and its rotation fulcrum is arranged on the fixed frame 501 and can rotate around the fulcrum and rotate relative to the fixed frame 501. A first tape picking rod is arranged on the driving arm 502, and when the driving arm 502 rotates, it drives the first tape picking rod to generate a tape picking action.

[0037] A driving structure 7 is arranged between the transmission arm 6 and the driving arm 502.

[0038] The driving structure 7 includes a convex block 701 arranged at the upper end of the driving arm 502 and an extension arm 702 arranged at the lower end of the transmission arm 6 that can drive the convex block 701 to rotate the driving arm 502. A return spring (not shown in the figure) is arranged between the convex block 701 and the fixed frame 501. When the transmission arm 6 is lifted, the extension arm 702 will drive the convex block 701 to rotate the driving arm 502 and drive the first tape picking rod to generate a tape picking action; when the transmission arm 6 descends, under the drive of the return spring, the extension arm 702 resets.

[0039] Embodiment 3

[0040] Reference Figure 5 、 6 , the first tape picking rod 12 is arranged on the first tape picking rod assembly 5. In this embodiment, the first tape picking rod assembly 5 can adopt the same structure as that in Embodiment 2 and will not be described in detail here. When the length of the tape pulled by a single tape picking rod cannot meet the needs of tape embroidery, preferably, in order to further increase the output of the tape, a second tape picking assembly 8 can also be arranged. The second tape picking assembly 8 includes a second tape picking rod 801 and a connecting frame 802 for installing the second tape picking rod 801. The connecting frame 802 is installed to connect the presser foot or / and the presser foot lifting sleeve. The connecting frame 802 is arranged on the presser foot or the presser foot lifting sleeve and can move up and down with the presser foot. Since the second tape picking rod 801 is arranged on the connecting frame 802, when the connecting frame 802 moves up and down, it will drive the second tape picking rod 801 to move up and down, thereby realizing the tape picking action.

[0041] Preferably, in order to smoothly pick up the tape 11, at least one guide shaft or / and guide wheel 9 for the tape is provided on the fixing frame 501. The tape 11 passes through the gap between the guide shaft or / and guide wheel 9 and is sewn to the needle bar. The fixing frame 501 can be directly or indirectly installed on the material rack 10 or / and the outer shaft of the transmission shaft 401 provided in the rope pendulum transmission assembly through an intermediate connection structure. At the same time, a guide frame for guiding the tape can also be provided separately, and at least one guide shaft and guide wheel are provided on the guide frame for guiding the tape.

[0042] Preferably, rollers are provided on the first and second tape picking rods, or the tape picking rods are rotatably arranged. Since the first and second tape picking assemblies can perform tape picking actions separately, when one tape picking rod is stationary, the lifting movement of the other tape picking rod will drive the tape to move. At this time, if rollers are provided or rotatably arranged, the tape will move more smoothly and faster, which can improve the efficiency of the embroidery tape.

[0043] Embodiment 4

[0044] Reference Figure 7 、 8 The first tape picking rod 12 is provided on the transmission arm 6, and further includes a second tape picking assembly 8. The second tape picking assembly 8 can have the same structure as that in Embodiment 3 and will not be described in detail here.

[0045] When the embroidery machine embroiders the tape, the rope pendulum mechanism and the rope pendulum drive mechanism are in an idle state and not working. At this time, the motor provided in the rope pendulum drive mechanism can drive the rope pendulum transmission assembly to perform a lifting movement, thereby driving the transmission arm 6 to lift and drive the first tape picking rod to pick up the tape. When the motor provided in the rope pendulum drive mechanism drives the first tape picking rod to move, it is not affected by other structures and can drive the first tape picking rod to move alone. Therefore, the controllable range of the drive is larger and the control is more accurate. At the same time, directly using the rope pendulum drive mechanism to drive does not require an additional motor to drive the tape picking rod to pick up the tape alone, saving space and cost.

[0046] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
