[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0022] Please see Figure 1-4 The present invention provides the following technical solution: a wire stretching device, including a base 1, a motor 4 installed at one end of the base 1, a bidirectional lead screw 5 provided at the output end of the motor 4, a slide plate 6 threadedly connected to both sides of the surface of the bidirectional lead screw 5, a movable frame 8 fixed at the upper end of the slide plate 6, a groove 7 corresponding to the slide plate 6 opened at the upper end of the base 1, telescopic rods 9 installed on both sides of the upper end of the movable frame 8, a pressure plate 10 provided at the output end of the telescopic rod 9, a chip collection assembly 3 provided at the upper end of the base 1, and a monitoring assembly 2 provided at the rear side between the two movable frames 8;
[0023] The monitoring component 2 includes a folding plate 21, a sliding rod 22, a fixed plate 23, a movable plate 24, a tension gauge 25, and a connecting ring 26. The folding plate 21 is fixed to the rear side of one end of the movable frame 8, and the sliding rod 22 is fixed to one end of the movable frame 8 at a position corresponding to the folding plate 21. The fixed plate 23 is fixed to one side of the upper end of the folding plate 21, and the movable plate 24 is fixed to one end of the sliding rod 22. The tension gauge 25 is installed on the fixed plate 23 near the movable plate 24, and the tension gauge 25 is connected to the movable plate 24 through the connecting ring 26.
[0024] Specifically, the monitoring component 2 also includes a limiting block 27 and a buzzer 28. The limiting block 27 is fixed on the upper end of the folding plate 21 away from the fixed plate 23, and the buzzer 28 is installed on the end of the limiting block 27 near the moving plate 24.
[0025] By adopting the above technical solution, the limit block 27 set at the upper end of the folding plate 21 can limit the moving plate 24, so as to avoid excessive pulling force and damage to the tension gauge 25. When the moving plate 24 contacts the buzzer 28 at one end of the limit block 27, the moving plate 24 triggers the switch at one end of the buzzer 28 to make the buzzer 28 alarm, thereby reminding the staff to shut down the equipment and avoid excessive pulling force and damage to the tension gauge 25.
[0026] Specifically, one end of the folding plate 21 has a sliding hole corresponding to the slide rod 22, the front end of the tension gauge 25 is equipped with a display screen, and the folding plate 21 and the movable frame 8, as well as the slide rod 22 and the movable frame 8, are all welded by spot welding.
[0027] By adopting the above technical solution, the slide bar 22 can slide in one end of the folding plate 21, and the display screen is set to facilitate the reading of the tension force on the tension gauge 25. Spot welding makes the folding plate 21 and the moving frame 8, as well as the slide bar 22 and the moving frame 8, more secure.
[0028] Specifically, the upper end of the limit block 27 is lower than the lower end of the slide bar 22, the buzzer 28 is equipped with a switch at the end away from the slide groove 7, and a silicone pad is glued to the position of the movable plate 24 corresponding to the switch.
[0029] By adopting the above technical solution, the slide bar 22 will not rub against the upper end of the limit block 27. When the switch is set so that the moving plate 24 contacts the switch, the buzzer 28 can be triggered to alarm. A silicone pad is glued to one end of the moving plate 24 at the position corresponding to the switch so that the moving plate 24 can be buffered and protected when it contacts the switch.
[0030] In this embodiment, when using the enameled wire stretching device, the device is installed in a suitable position, and both ends of the enameled wire are placed in the movable frame 8. The telescopic rod 9 is activated to push the pressure plate 10 to hold and fix the enameled wire. Then, the motor 4 is turned on to drive the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the two slide plates 6 to move away from each other in the slide groove 7 in the base 1. The movement of the two slide plates 6 causes the two movable frames 8 to move and stretch the enameled wire. By setting the monitoring component 2, when the two movable frames 8 move to stretch the enameled wire, the slide rod 22 slides in the folding plate 21. The movement of the slide rod 22 causes the movable plate 24 to move. The movable plate 24 is connected to... The ring 26 pulls the tension gauge 25, and the tension on the tension gauge 25 can be observed through the display screen on the tension gauge 25, thus knowing the tension on the enameled wire. The tension on the enameled wire can be monitored and observed by setting the monitoring component 2. The limit block 27 set at the upper end of the folding plate 21 can limit the moving plate 24 to avoid damage to the tension gauge 25 due to excessive tension. When the moving plate 24 contacts the buzzer 28 at one end of the limit block 27, the moving plate 24 triggers the switch at one end of the buzzer 28 to make the buzzer 28 sound an alarm, thereby reminding the staff to shut down the equipment and avoid damage to the tension gauge 25 due to excessive tension.

The collection box 31 is provided on the upper end of the base 1, and the positioning plate 32 is fixed on one side of the upper end of the base 1 at a position corresponding to the collection box 31. The collection box 31 and the positioning plate 32 are connected by the fixing bolt 35. One end of the collection box 31 is provided with a fixing hole 36 corresponding to the fixing bolt 35. The lower end of the movable frame 8 is provided with a through groove 33 corresponding to the collection box 31, and the side of the through groove 33 is provided with an arc-shaped edge 34.
[0032] By adopting the above technical solution, the collection box 31 is placed on the base 1 and inserted into the through groove 33 at the lower end of the movable frame 8. The through groove 33 has an arc-shaped edge 34 on its side to facilitate the insertion of the collection box 31 into the through groove 33 at the lower end of the movable frame 8. When one end of the collection box 31 contacts the side of the positioning plate 32, the fixing bolt 35 is passed through the positioning plate 32 and screwed into the fixing hole 36 at one end of the collection box 31 to achieve the effect of limiting and fixing the collection box 31. By setting the chip collection component 3, the waste chips that fall off due to the stretching of the enameled wire can be collected to avoid the waste chips from contaminating the upper end of the base 1.
[0033] Specifically, after the collection box 31 is installed on the base 1, the side of the collection box 31 is tangent to the inner wall of the positioning plate 32, and the positioning plate 32 has through holes corresponding to the fixing bolts 35.
[0034] By adopting the above technical solution, after the collection box 31 is installed on the base 1, there will be no scraping between the side of the collection box 31 and the inner wall of the positioning plate 32, and the fixing bolt 35 can be screwed into the fixing hole 36 at one end of the collection box 31 through the positioning plate 32.
[0035] In this embodiment, by setting the chip collection assembly 3, the collection box 31 is placed on the base 1 and inserted into the through groove 33 at the lower end of the movable frame 8. The through groove 33 has an arc-shaped edge 34 on its side to facilitate the insertion of the collection box 31 into the through groove 33 at the lower end of the movable frame 8. When one end of the collection box 31 contacts the side of the positioning plate 32, the fixing bolt 35 is passed through the positioning plate 32 and screwed into the fixing hole 36 at one end of the collection box 31 to achieve the effect of limiting and fixing the collection box 31. By setting the chip collection assembly 3, the waste chips that fall off due to the stretching of the enameled wire can be collected, avoiding the waste chips from contaminating the upper end of the base 1.
[0036] In this utility model, the force gauge 25 is a previously disclosed technology, and the selected model is NK-50.
[0037] The buzzer 28 in this utility model is a previously disclosed technology, and the selected model is AD16-22SM.
[0038] The structure and working principle of the base 1, motor 4, bidirectional lead screw 5, slide plate 6, slide groove 7, moving frame 8, telescopic rod 9, and pressure plate 10 in this utility model have been disclosed in an automatic enameled wire stretching device disclosed in Chinese patent application number 2022200159427. Its working principle is to place both ends of the enameled wire into the moving frame 8, activate the telescopic rod 9 to push the pressure plate 10 to press and fix the enameled wire, and then activate the motor 4 to drive the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the two slide plates 6 to move away from each other in the slide groove 7 in the base 1. The movement of the two slide plates 6 causes the two moving frames 8 to move and stretch the enameled wire.
[0039] The working principle and usage process of this utility model are as follows: When using the enameled wire stretching device, install the device in a suitable position, place both ends of the enameled wire into the movable frame 8, activate the telescopic rod 9 to push the pressure plate 10 to press and fix the enameled wire, then activate the motor 4 to drive the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the two slide plates 6 to move away from each other in the slide groove 7 in the base 1. The movement of the two slide plates 6 causes the two movable frames 8 to move and stretch the enameled wire. By setting the monitoring component 2, when the two movable frames 8 move to stretch the enameled wire, the slide rod 22 slides in the folding plate 21. The movement of the slide rod 22 causes the movable plate 24 to move. The movable plate 24 pulls the tension gauge 25 through the connecting ring 26. The tension on the tension gauge 25 can be observed through the display screen on the tension gauge 25, thus knowing the tension applied to the enameled wire. By setting the monitoring component 2, the tension applied to the enameled wire can be monitored and observed. By setting the limit block 27 at the upper end of the folding plate 21, the tension applied to the enameled wire can be monitored and observed. The moving plate 24 can be limited to prevent excessive tension from damaging the tension gauge 25. When the moving plate 24 contacts the buzzer 28 at one end of the limiting block 27, the moving plate 24 triggers the switch at one end of the buzzer 28 to make the buzzer 28 sound an alarm, thereby reminding the staff to shut down the equipment and prevent excessive tension from damaging the tension gauge 25. By setting the chip collection assembly 3, the collection box 31 is placed on the base 1 and inserted into the through groove 33 at the lower end of the moving frame 8. The through groove 33 has an arc edge 34 on its side to facilitate the insertion of the collection box 31 into the through groove 33 at the lower end of the moving frame 8. When one end of the collection box 31 contacts the side of the positioning plate 32, the fixing bolt 35 is passed through the positioning plate 32 and screwed into the fixing hole 36 at one end of the collection box 31 to achieve the effect of limiting and fixing the collection box 31. By setting the chip collection assembly 3, the waste chips that fall off during the stretching of the enameled wire can be collected to prevent the waste chips from contaminating the upper end of the base 1.
