[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figure 1 to Figure 4 , a metal monofilament online quick splicing device, comprising a frame 1 and two elbow forming devices and two extrusion devices installed together on the frame 1, wherein:

[0025] For each of the elbow forming devices, it includes a motor (not shown in the figure), a turntable 21, a forming wheel group and a first driving cylinder (not shown in the figure). The turntable 21 can be rotatably mounted on the frame 1. The motor is connected to the turntable 21 to drive the turntable 21 to rotate. The output shaft of the motor is coaxially arranged with the turntable 21; the forming wheel group includes a sun gear 22 and a planetary gear 23. The sun gear 22 and the planetary gear 23 are used to cooperate with the bending of the metal monofilament 4. The sun gear 22 and the planetary gear 23 are fixedly mounted on the turntable 21 respectively. And their center lines are parallel to each other, the diameters of the sun gear 22 and the planetary gear 23 are respectively smaller than the diameter of the turntable 21, the sun gear 22 is coaxially arranged with the turntable 21, and the two rotate coaxially, the planetary gear 23 is eccentrically arranged relative to the turntable 21 (the planetary gear 23 and the turntable 21 are not coaxial), and a metal monofilament channel is formed between the planetary gear 23 and the sun gear 22, and the metal monofilament 4 can pass through the metal monofilament channel, so that the planetary gear 23 and the sun gear 22 cooperate to bend the end of the metal monofilament 4 into an elbow. When bending the metal monofilament 4, the sun gear 22 and the planetary gear 23 cooperate to clamp the end of the metal monofilament 4, and then the planetary gear 23 rotates around the sun gear 22, so that the planetary gear 23 can bend the metal monofilament 4. During bending, production can continue without stopping, that is, the metal monofilament 4 can be bent while moving forward under the traction of an external traction mechanism. During the bending process, the first drive cylinder drives the motor and the forming wheel group to move as a whole to prepare for separation from the elbow. After the bending is completed, the forming wheel group is completely separated from the elbow.

[0026] The first driving cylinder is preferably a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, which is mounted on the frame 1. The first driving cylinder is connected to the motor to drive the motor to move to separate the forming wheel group from the elbow, so as to facilitate the movement of the metal monofilament 4 with the elbow under the traction of an external traction mechanism, thereby ensuring the production continuity of the production line.

[0027] The center lines of the two sun gears 22 are perpendicular to each other so that one of the elbows can hook the other elbow when it moves under the traction of the external traction mechanism; in actual production, the metal monofilament 4 on the production line moves horizontally, so that the elbow of the metal monofilament 4 being processed (such as re-twisting) on ​​the production line can be kept vertical, and the elbow of the other metal monofilament 4 to be connected can be kept horizontal, so that the vertical elbow can hook the horizontal elbow when it moves under the traction of the traction mechanism and drive it to move together. The relative positions of the forming wheel groups of the two elbow forming devices need to be arranged so that the two elbows can be hooked smoothly.

[0028] For each of the extrusion devices, it includes a second driving cylinder (not shown in the figure), a pressure plate 31 and a fixed block 32. The second driving cylinder is preferably a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. The second driving cylinder is installed on the frame 1 and the pressure plate 31 is installed on the second driving cylinder so that the pressure plate 31 cooperates with the fixed block 32 to extrude the elbow to make the elbow smaller.

[0029] The output shafts of the driving cylinders of the two extrusion devices are perpendicular to each other, so the moving directions of the two pressing plates 31 are also perpendicular. One of the pressing plates 31 can be moved vertically to cooperate with the fixed block 32 to extrude the vertical elbow, while the other pressing plate 31 can be moved horizontally to cooperate with the fixed block 32 to extrude the horizontal elbow, so that the joint formed by the two elbows can be squeezed and reduced, which is convenient for the joint to pass through the twisting head, traction wheel, etc. The two extrusion devices are preferably arranged in a staggered manner along the advancing direction of the metal monofilament to facilitate the sequential extrusion of the two elbows. When the joint is squeezed and reduced, the machine can be operated without stopping, and the metal monofilament 4 can be squeezed while moving and sliding along the pressing plate 31. As a preferred solution, the roughness Ra of the surface for contacting the elbow on the pressing plate 31 and the fixed block 32 is less than or equal to 1.6μm. , so that the surface of the pressing plate 31 and the fixed block 32 is relatively smooth, and the friction is relatively small, so that when the pressing plate 31 extrudes the metal monofilament 4, the metal monofilament 4 can still move.

[0030] Furthermore, the diameter of the sun gear 22 is larger than the diameter of the planetary gear 23, so as to facilitate the formation of an elbow with a relatively large opening and facilitate the two elbows to be hooked together.

[0031] Furthermore, the sun gear 22 and the planetary gear 23 are both located within the area surrounded by the outer contour of the turntable 21, which can make the structure more compact, prevent the planetary gear 23 from interfering with another metal monofilament 4 after moving, and facilitate the installation layout of the overall structure.

[0032] Furthermore, the output shaft of the second driving cylinder of one of the extrusion devices is vertically arranged and a groove is arranged on the pressing plate 31 of the extrusion device as a moving channel of one of the elbows (vertical elbow) to prevent the elbow from tilting during the downward movement of the pressing plate 31. When the other elbow (horizontal elbow) is extruded, the joint can be supported by the support plate, and the horizontal elbow will not tilt when the pressing plate 31 cooperates with the fixed block 32 for extrusion. Of course, a groove can also be arranged on the other pressing plate 31.

[0033] Furthermore, the groove depth of the groove is 2 mm to 10 mm. The groove depth can be set relatively small, and the height of the elbow can be reduced as much as possible while ensuring that the vertical elbow does not fall, so that the two elbows hooked together are not easy to fall off.

[0034] Furthermore, it also includes a plurality of guide wheels for receiving the metal monofilament 4, so as to ensure that after the forming wheel group withdraws the metal monofilament 4, there are still guide wheels to support the metal monofilament 4, so that the two elbows can be hooked together smoothly.

[0035] Furthermore, the distance between the center lines of the sun gear 22 and the planetary gear 23 is 30 mm to 100 mm, which can make the elbow longer, increase the length of the joint formed by the two elbows, and effectively prevent the two elbows from separating.

[0036] Furthermore, the diameter of the sun gear 22 is 100 mm to 300 mm, and the diameter of the planetary gear 23 is 25 mm to 50 mm, which can be adapted to the bending of the metal monofilament 4 with a diameter of 2 mm to 5 mm.

[0037] The utility model can bend two metal monofilaments 4 without stopping the machine, so that the elbows of the two metal monofilaments 4 are connected, and an extrusion device is used to extrude the elbows to reduce the size of the elbows, thereby ensuring the continuity of production and improving production efficiency.

[0038] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
