Description

Technical Field

[0001] The utility model relates to the technical field of enameling machines, in particular to a lead tensioning device for an enameling machine. Background Technique

[0002] The enameling machine is an important device for producing enameled wires in the electromagnetic wire industry. Its function is to evenly coat a layer of insulating paint on the outside of the processed copper wire (or aluminum wire). During the processing, it is necessary to first tension the leads for coordinated processing, and at this time, a tensioning device will be used.

[0003] The existing tensioning device controls the tension of the lead through a tensioning spring. When in use, some springs will cause different tension control of the lead due to their own quality or deviation during installation, and at the same time, it is impossible to individually adjust the tension degree of the problematic lead, thus reducing the quality of lead production. Therefore, we need to propose a lead tensioning device for an enameling machine. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-6 , the present utility model provides a technical solution: a lead wire tensioning device for an enameling machine, including a support plate 1. Limiting mechanisms 2 are installed on both the front and rear sides of the top of the support plate 1. U-shaped brackets 3 are equidistantly installed between the limiting mechanisms 2 on the top of the support plate 1. A U-shaped support plate 4 is slidably connected to the inner side of the U-shaped bracket 3. A moving wheel 5 is rotatably connected to the inner side of the U-shaped support plate 4 through a bearing seat. A lead screw 6 is rotatably connected to the top of the U-shaped support plate 4 through a bearing seat. The top of the lead screw 6 penetrates through the U-shaped bracket 3 and extends to the outside of the U-shaped bracket 3 and is connected to a crank 7. An adjusting mechanism 8 and a supporting mechanism 9 are respectively equidistantly arranged at the bottom of the support plate 1;

[0023] Through the settings of the limiting mechanism 2, U-shaped support plate 4, moving wheels 5, lead screw 6, crank 7 and adjustment mechanism 8, during use, the height can be adjusted according to requirements through the adjustment mechanism 8. After adjusting to the appropriate height, the lead is limited by the limiting mechanism 2 to prevent the lead from shifting during movement. When there is a problem with the tension of the lead, turn the crank 7. The crank 7 drives the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the U-shaped bracket 3, the lead screw 6 drives the U-shaped support plate 4 to move. The U-shaped support plate 4 drives the moving wheels 5 to move. The moving moving wheels 5 can adjust the tension of the lead, improving the quality of lead production and the practicality of the device at the same time.

[0024] Please refer to Figure 1-6 , the limiting mechanism 2 includes a fixed tube 21. The bottom end of the fixed tube 21 is connected to the top of the support plate 1. A telescopic rod 22 is slidably connected to the inner cavity of the fixed tube 21. The top end of the telescopic rod 22 penetrates through the fixed tube 21 and extends to the outside of the fixed tube 21 and is connected to a limiting bracket 23. A limiting wheel 24 is rotatably connected to the inner side of the limiting bracket 23 through a bearing seat. The bottom of the inner cavity of the fixed tube 21 is connected to a return spring 25. The top end of the return spring 25 is connected to the bottom end of the telescopic rod 22. When the lead passes through the limiting wheel 24, the lead can be limited by the limiting wheel 24 to avoid the lead from shifting during movement. At the same time, the tension of the lead can be regulated through the return spring 25 to keep the lead in a tensioned state all the time.

[0025] The adjustment mechanism 8 includes a bottom plate 81. The front and rear sides of the top of the bottom plate 81 are both slidably connected with moving plates 82. The top ends of the moving plates 82 are equally spaced and hinged with support rods 83. The top ends of the support rods 83 are hinged to the bottom of the support plate 1. A first support plate 84 and a second support plate 85 are respectively installed on the top of the bottom plate 81 and outside the moving plates 82. A threaded rod 86 is rotatably connected to the front of the first support plate 84 through a bearing seat. The front end of the threaded rod 86 penetrates through the moving plate 82 and the second support plate 85 in sequence and extends to the outside of the second support plate 85 and is connected to a turntable. When it is necessary to adjust the height according to actual requirements, turn the turntable. The turntable drives the threaded rod 86 to rotate. Since the threaded rod 86 is threadedly connected to the moving plate 82, the rotating threaded rod 86 drives the moving plate 82 to approach. The moving plate 82 drives the bottom ends of the support rods 83 to approach. Since the support rods 83 are arranged in a cross shape, when the bottom ends of the support rods 83 move, they simultaneously support the support plate 1 to move it upward. The support plate 1 can drive the limiting mechanism 2, U-shaped bracket 3, U-shaped support plate 4, moving wheels 5, lead screw 6 and crank 7 to move, which is convenient for use and facilitates height adjustment.

[0026] The support mechanism 9 includes a support tube 91. The bottom end of the support tube 91 is connected to the top of the bottom plate 81. A moving rod 92 is slidably connected to the inner cavity of the support tube 91. The top end of the moving rod 92 penetrates through the support tube 91 and extends to the outside of the support tube 91 to be connected to the bottom of the support plate 1, which can support the support plate 1 and increase the stability of the support plate 1 during movement. Limit sliders are installed on both sides of the U-shaped support plate 4. Limit chutes are provided on the inner side of the U-shaped bracket 3 at positions corresponding to the limit sliders. The surface of the limit slider is slidably connected to the inner cavity of the limit chute, which can limit the U-shaped support plate 4 and prevent the U-shaped support plate 4 from shifting when the lead screw 6 rotates, thus affecting the normal operation of the moving wheels 5 inside the U-shaped support plate 4.

[0027] Support sliders are equidistantly installed at the bottom of the moving plate 82. Support chutes are provided on the top of the bottom plate 81 at positions corresponding to the support sliders. The surface of the support slider is slidably connected to the inner cavity of the support chute, which can support the moving plate 82 and at the same time reduce the friction between the moving plate 82 and the bottom plate 81, facilitating the movement of the moving plate 82. Limit blocks are installed on both sides of the telescopic rod 22. Limit grooves are provided in the inner cavity of the fixed tube 21 at positions corresponding to the limit blocks. The surface of the limit block is slidably connected to the inner cavity of the limit groove, which can limit the telescopic rod 22 and prevent the telescopic rod 22 from rotating, thus affecting the normal use of the limit wheel 24.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
