Description

Technical Field

[0001] This utility model relates to the field of PE yarn splicing devices, and in particular to an ultrasonic splicing device for PE yarn. Background Technology

[0002] Polyethylene (PE) yarn is widely used in the processing of textile products such as car floor mats and household carpets due to its excellent abrasion resistance, moisture resistance and easy cleaning properties.

[0003] In existing technologies, when PE yarn breaks or needs to be replaced, it is usually necessary to butt-connect two PE yarns to make them a single, usable yarn. The traditional method of splicing is manual soldering with a soldering iron, which involves using an electric heating element to locally heat and melt the ends of the yarns before pressing them together. However, PE yarn has a low melting point and poor thermal stability, and soldering with a soldering iron can easily lead to uneven melting and carbonization, thus affecting the connection strength of the PE yarn. Furthermore, this hot-melt operation is cumbersome, inconvenient to use, and has a long curing time, which affects the splicing efficiency of PE yarn.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an ultrasonic splicing device for PE yarn that is easy to use and improves splicing efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: an ultrasonic splicing device for PE yarn, comprising a base, a lifting and adjusting mechanism, a lifting seat, a rotary table, a dual-axis moving mechanism, an ultrasonic welding head, a cooling air pipe, and a splicing platform;

[0007] The lifting adjustment mechanism is located on the top of the base, and the movable end of the lifting adjustment mechanism is connected to the lifting base. The lifting adjustment mechanism is used to drive the lifting base to move vertically up and down.

[0008] The rotating platform is located at the side end of the lifting seat, and the movable end of the rotating platform is connected to the dual-axis moving mechanism. The ultrasonic welding head is located on the dual-axis moving mechanism, and the rotating platform is used to rotate and adjust the angle of the ultrasonic welding head.

[0009] The wiring platform is located on the base below the ultrasonic welding head. The top surface of the wiring platform is provided with a wire clamping groove, which is used to place two PE yarns to be ultrasonically welded. The ultrasonic welding head is used to weld the two PE yarns in the wire clamping groove together.

[0010] The cooling air pipe is inclined at the side end of the ultrasonic welding head. The cooling air pipe is used to output cooling airflow. The outlet of the cooling air pipe is set towards the bottom of the ultrasonic welding head. The cooling air pipe is used to cool and solidify the weld joint of the PE yarn.

[0011] Using the above technical solution, in the ultrasonic splicing device for PE yarn, the dual-axis moving mechanism includes a horizontal linear module and a vertical linear module.

[0012] The horizontal linear module is connected to the movable end of the rotary table, the vertical linear module is connected to the movable end of the horizontal linear module, and the movable end of the vertical linear module is connected to the ultrasonic welding head. The horizontal linear module is used to adjust the horizontal position of the ultrasonic welding head, and the vertical linear module is used to drive the ultrasonic welding head to press down and abut against the clamping groove.

[0013] The PE yarn ultrasonic splicing device using the above technical solution further includes a swing clamp, one end of which is rotatably connected to the side wall of the ultrasonic welding head, and the other end of which is provided with a clamp for clamping and fixing the cooling air pipe.

[0014] In the PE yarn ultrasonic splicing device described above, the clamping groove has an arc-shaped structure.

[0015] In the PE yarn ultrasonic splicing device described above, the splicing platform is made of aluminum alloy.

[0016] Using the above technical solution, in the ultrasonic splicing device for PE yarn, the inner wall of the clamping groove is coated with a Teflon coating.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The clamping groove of this invention can limit and align two PE yarns, preventing them from sliding or misaligning during welding, thereby improving the welding accuracy. The rotating table can adjust the angle of the ultrasonic welding head to ensure it is always perpendicular to the yarn, thus improving the welding quality. After welding, the cooling pipe can directionally cool the yarn weld joint through the cooling airflow to shorten the curing time and effectively improve the splicing efficiency and joint strength.

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and Figure 2As shown, this utility model embodiment provides an ultrasonic splicing device for PE yarn, including a base 1, a lifting and adjusting mechanism 2, a lifting seat 3, a rotary table 4, a dual-axis moving mechanism 5, an ultrasonic welding head 6, a cooling air pipe 7, and a splicing platform 8; the lifting and adjusting mechanism 2 is located on the top of the base 1, and its movable end is connected to the lifting seat 3, which drives the lifting seat 3 to move vertically; the rotary table 4 is located on the side of the lifting seat 3, and its movable end is connected to the dual-axis moving mechanism 5; the ultrasonic welding head 6 is located on the dual-axis moving mechanism 5, and the rotary table 4 is used to rotate and adjust the angle of the ultrasonic welding head 6; due to the ultrasonic welding head The vibration direction of the ultrasonic welding head 6 needs to be perpendicular to the yarn axis. However, errors in the structure, preset installation angle, or replacement of the ultrasonic welding head 6 often cause deviations between its working surface and the yarn clamping line, thus affecting the welding quality. Therefore, by setting a rotating table 4 on the lifting base 3, the ultrasonic welding head 6 can be angled around the vertical axis. The angle can be calibrated after the ultrasonic welding head 6 is replaced to keep it perpendicular to the yarn mating surface. In addition, the rotating table 4 also makes it easier for engineers to set the optimal welding angle according to different specifications or materials of PE yarn to meet diverse welding process requirements. Furthermore, the lifting adjustment mechanism 2 can adjust the distance between the ultrasonic welding head 6 and the wiring platform 8 to adapt to the installation height requirements of different specifications of ultrasonic welding heads 6.

[0027] The junction box 8 is located on the base 1 below the ultrasonic welding head 6. The top surface of the junction box 8 has a wire clamping groove 81 for holding two PE yarns to be ultrasonically welded. The ultrasonic welding head 6 is used to weld the two PE yarns together in the wire clamping groove 81. Because PE yarns are relatively soft and easily slide, the wire clamping groove 81 allows the two yarns to be aligned before welding and prevents them from shifting or lifting during the welding process, thereby improving the welding effect. During ultrasonic welding, the ultrasonic welding head 6 is pressed downwards under the drive of the dual-axis moving mechanism 5, contacting the PE yarns in the wire clamping groove 81 to locally melt and bond the ends of the PE yarns through high-frequency vibration.

[0028] The cooling air pipe 7 is inclinedly disposed on the side end of the ultrasonic welding head 6. The cooling air pipe 7 is used to output cooling airflow, and the outlet of the cooling air pipe 7 is set towards the bottom of the ultrasonic welding head 6. The cooling air pipe 7 is used to cool and solidify the weld joint of the PE yarn. After welding, the weld joint of the PE yarn is still in a high temperature state. The cooling air pipe 7 blows the weld joint with cooling airflow to cool and solidify it, which not only improves the forming quality of the weld joint of the PE yarn, but also effectively shortens the cooling waiting time and improves the welding efficiency.

[0029] like Figure 2As shown, the dual-axis moving mechanism 5 further includes a horizontal linear module 51 and a vertical linear module 52. The horizontal linear module 51 is connected to the movable end of the rotary table 4, and the vertical linear module 52 is connected to the movable end of the horizontal linear module 51. The movable end of the vertical linear module 52 is connected to the ultrasonic welding head 6. The horizontal linear module 51 is used to adjust the horizontal position of the ultrasonic welding head 6, and the vertical linear module 52 is used to drive the ultrasonic welding head 6 to press down and abut against the wire clamping groove 81. The horizontal linear module 51 can adjust the position of the ultrasonic welding head 6 in the horizontal direction, so that it is aligned with the fusion point with the PE yarn, thereby improving the welding accuracy. The vertical linear module 52 can drive the ultrasonic welding head 6 to press down in the vertical direction, so that the ultrasonic welding head 6 contacts the PE yarn in the wire clamping groove 81 and applies appropriate pressure to complete the ultrasonic welding.

[0030] Furthermore, it also includes a swing clamp 9, one end of which is rotatably connected to the side wall of the ultrasonic welding head 6, and the other end of which is provided with a clamp 91 for clamping and fixing the cooling air pipe 7. With this configuration, the swing angle of the cooling air pipe 7 can be adjusted, so that when changing different ultrasonic welding heads 6, the output direction of the cooling airflow can be adjusted by adjusting the rotation angle of the swing clamp 9, thereby improving the cooling effect.

[0031] Furthermore, the clamping groove 81 has an arc-shaped structure. This design allows the clamping groove 81 to fully fit with the PE yarn, preventing the yarn from rolling or shifting during the welding process.

[0032] Furthermore, the junction box 8 is made of aluminum alloy.

[0033] Furthermore, the inner wall of the clamping groove 81 is coated with a Teflon coating (not shown). During the ultrasonic welding process, the end of the PE yarn will melt under high-frequency vibration. The molten PE yarn is easy to adhere to the metal surface. By coating the inner wall of the clamping groove 81 with a Teflon coating, the adhesion force between the molten material and the metal surface can be reduced, so that the cooled PE yarn can be easily demolded and adhesive residue can be avoided.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
