Description

Technical Field

[0001] The present invention relates to the technical field of a wire catcher and its application, and in particular to a wire catcher and its application. Background Art

[0002] The production of enameled wire is a continuous process. When a wire reel is full of wire, it needs to be replaced with an empty reel without stopping the machine. For a long time, this operation has been achieved by operators pulling the wire manually. With the improvement of enameled wire process and baking technology, the production speed of enameled wire is getting faster and faster, which increases the labor intensity of operators manually changing reels. Moreover, the higher the production speed, the lower the success rate of manual reel change, which causes a lot of waste in production.

[0003] In order to increase production speed and meet production needs, wire companies have begun to use automatic reel changers. Although the wire catchers on the current automatic reel changers can achieve the purpose of catching wires, most of them are only suitable for small wires, and are not suitable for some large-sized wires (diameter of 3mm and above).

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1-9 As shown, a wire catcher comprises a mounting seat 1, an upper clamping block 2, a lower clamping block 3, a first elastic member 4 and a second elastic member 5;

[0043] The surface of the mounting seat 1 is raised to form a pivot boss 11, and the mounting seat 1 is divided by the pivot boss 11, with a mounting groove 12 on one side and a second lower mounting cylindrical groove 14 on the other side; the bottom surface of the mounting groove 12 is downwardly provided with a first lower mounting cylindrical groove 13, and the first lower mounting cylindrical groove 13 and the second lower mounting cylindrical groove 14 do not pass through the mounting seat 1;

[0044] The lower clamping block 3 is movably mounted in the mounting groove 12, and a first upper mounting cylindrical groove 31 is formed on the lower bottom surface of the lower clamping block 3, the first upper mounting cylindrical groove 31 does not penetrate the lower clamping block 3, the first upper mounting cylindrical groove 31 is arranged corresponding to the first lower mounting cylindrical groove 13, the first elastic member 4 is mounted in the first lower mounting cylindrical groove 13 and the first upper mounting cylindrical groove 31, and the two ends of the first elastic member 4 are respectively against the first lower mounting cylindrical groove 13 and the first upper mounting cylindrical groove 31;

[0045] The upper clamp block 2 is installed above the lower clamp block 3, and a second upper mounting cylindrical groove 21 is provided on the lower bottom surface of the upper clamp block 2. The second upper mounting cylindrical groove 21 does not penetrate the upper clamp block 2, and the second upper mounting cylindrical groove 21 is correspondingly arranged with the second lower mounting cylindrical groove 14. The second elastic member 5 is installed in the second upper mounting cylindrical groove 21 and the second lower mounting cylindrical groove 14, and the two ends of the second elastic member 5 are respectively against the groove surfaces of the second upper mounting cylindrical groove 21 and the second lower mounting cylindrical groove 14;

[0046] The upper clamping block 2 and the lower clamping block 3 form a wire catching opening, and the upper clamping block 2 performs pitch rotation relative to the mounting seat 1 with the pivot boss 11 as the axis.

[0047] The present invention captures the wire through the wire entry formed by the upper clamp block 2 and the lower clamp block 3, and at the same time, the second elastic member 5 presses on the tail of the upper clamp block 2, so that the clamping space between the upper clamp block 2 and the lower clamp block 3 has sufficient pressing force, so that the captured wire will not get loose. At the same time, by arranging the first elastic member 4 between the mounting seat 1 and the lower clamp block 3, when clamping a wire with a larger diameter, there can also be an elastic distance between the lower clamp block 3 and the mounting seat 1 to adapt to the clamping of the wire with a larger diameter, further preventing the captured wire from getting loose.

[0048] Further explanation, it also includes an upper bite part 6, which is a metal wire. Two mounting holes 22 are vertically opened on the lower bottom surface of the upper clamping block 2. The two ends of the upper bite part 6 are bent and fixedly installed in the mounting holes 22 respectively. The upper bite part 6 is attached to the lower bottom surface of the upper clamping block 2.

[0049] To further illustrate, the lower clamping block 3 is provided with a bite groove 32 matching the upper bite piece, the cross section of the bite groove 32 is "V" shaped, and the upper bite piece 6 is accommodated in the bite groove 32 in a natural state;

[0050] The upper clamp block 2 and the lower clamp block 3 are combined in a state of being close to each other, and the wire catching opening formed by the upper clamp block 2 and the lower clamp block 3 is trumpet-shaped. In order to better capture the wire, the upper bite piece 6 cooperates with the bite groove 32, and the upper bite piece 6 has good elasticity, which can further enhance the clamping force.

[0051] Furthermore, it also includes a fixing bolt 7; the lower clamping block 3 is provided with a third upper mounting cylindrical groove 33, the third upper mounting cylindrical groove 33 does not pass through the lower clamping block 3, and the inner groove surface of the third upper mounting cylindrical groove 33 is provided with an internal thread; the mounting seat 1 is provided with a third lower mounting cylindrical groove 15, the third lower mounting cylindrical groove 15 passes through the mounting seat 1, and the groove diameter of the third lower mounting cylindrical groove 15 is larger than the diameter of the fixing bolt 7; the fixing bolt 7 passes through the third lower mounting cylindrical groove 15 and the third upper mounting cylindrical groove 33 in sequence, and the fixing bolt 7 is spirally connected with the internal thread of the third upper mounting cylindrical groove 33. Since the first elastic member 4 is squeezed and stressed between the mounting seat 1 and the lower clamping block 3, in order to ensure that the wire catching opening between the upper clamping block 2 and the lower clamping block 3 maintains a fixed opening distance, the fixing bolt 7 is spirally connected to the internal thread of the third upper mounting cylindrical groove 33, and the lower end of the fixing bolt 7 is stuck in the third lower mounting cylindrical groove 15, thereby fixing the position height between the mounting seat 1 and the lower clamping block 3.

[0052] Further explanation, the upper clamp block 2 is provided with a pivot hole 23, the pivot hole 23 penetrates the upper clamp block 2, the pivot boss 11 is provided in the pivot hole 23, the pivot boss 11 and the upper clamp block 2 are correspondingly provided with a pivot hole 23 in the transverse direction, the pivot hole 23 is provided with a pivot pin 24, and the pivot pin 24 enables the upper clamp block 2 to perform pitch rotation relative to the mounting seat 1. The upper clamp block 2 rotates around the hinge point between it and the mounting seat 1 to achieve pitch action, and at the same time, the rotation angle range is limited by the telescopic contact of the first elastic member 4 and the second elastic member 5, and its structure is simple, the cost is low, and it is easy to implement.

[0053] To further explain, the upper clamp block 2 has a first inclined surface 24, and the lower clamp block 3 has a second inclined surface 34. The inclination directions of the first inclined surface 24 and the second inclined surface 34 are opposite. The first inclined surface 24 is inclined downward from left to right, and the second inclined surface 34 is inclined upward from left to right.

[0054] Further explanation, the inclination angle α of the first inclined surface 24 and the inclination angle δ of the second inclined surface 34 are both not greater than 15°. In this embodiment, the wire catching opening formed by the combination of the upper clamping block 2 and the lower clamping block 3 is trumpet-shaped, and its opening and closing angle is limited to within 30° to improve the success rate of catching the wire.

[0055] Further explanation, the number of the first elastic member 4 and the fixing bolt 7 is two, and the first lower mounting cylindrical groove 13, the first upper mounting cylindrical groove 31, the third upper mounting cylindrical groove 33 and the third lower mounting cylindrical groove 15 are all provided with two. In order to better adapt to wires of different wires, especially large wires with a diameter greater than 3 mm, this embodiment is provided by cooperating with two first elastic members 4, two fixing bolts 7 and one second elastic member 5, which can further avoid problems such as loosening of the wire reel.

[0056] like Fig.10 As shown, an automatic reel-changing device includes a wire feeding mechanism 101 and two wire-receiving mechanisms 102. The two wire-receiving mechanisms 102 are arranged side by side horizontally, and the rotation directions of the two wire-receiving mechanisms 102 are opposite. A wire grabbing mechanism 103 is provided between the two wire-receiving mechanisms 102, and the edges of the two wire-receiving mechanisms 102 are fixedly installed with a wire catcher 100 as described above. During the specific use of the automatic reel-changing device, when one of the wire-receiving mechanisms 102 needs to be replaced, the wire feeding mechanism 101 moves horizontally to one end of the thread, pushes the wire through the wire grabbing mechanism 103, and causes the wire to be caught by the wire catcher 100 on the wire-receiving mechanism 102 on the other side, and then the wire begins to be wound on the other wire-receiving mechanism 102. The present invention overcomes the disadvantages of high quality risks, high failure rate and slow speed of manual reel-changing, speeds up production, significantly improves production efficiency, and effectively reduces labor intensity and labor costs.

[0057] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way.
