Description

Technical Field

[0001] The utility model relates to the technical field of bulb manufacturing, in particular to a wire-releasing device with an alarm device applied to a coreless wire winding machine. Background Art

[0002] In order to solve the problem of winding long filaments, existing manufacturers have invented a dual-power wire winding machine. The traditional wire-releasing device does not have an alarm prompt function. Even if the tungsten wire in the wire-releasing device is consumed, other mechanisms are still running. Workers cannot replace the tungsten wire reel or stop the machine in time, resulting in a waste of resources.

[0003] The existing patent (Announcement No.: CN205211707U) discloses a wire feeding machine with an alarm device applied to a coreless wire winding machine. A sensor is installed next to the tungsten wire disc. When the sensor detects that the tungsten wire disc is not rotating or the rotation speed is abnormal, it will feedback a signal to the alarm device. The alarm device will send different warning signals according to the feedback signal of the sensor, so that workers can find the abnormality of the wire feeding device of the wire winding machine at the first time, and then effectively deal with it, thereby improving production efficiency. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:

[0004] It is sensed by sensors during use, but direct sensing by sensors is prone to false sensing or slow response, affecting use, and the rotating shaft is prone to shaking when idling, causing damage and bringing unnecessary losses to the production work. Utility Model Content

In addition, by arranging a driven rod and an auxiliary block on the outer side of the rotating shaft, the auxiliary block touches the sensor when the rotating shaft shakes, thereby quickly realizing the alarm work and reminding the staff that the tungsten wire disk needs to be replaced.

[0013] Through the above technical solution, it is convenient to use the support block to limit the sensor, which facilitates the sensing work of the auxiliary block.

[0017] Through the above technical solution, it is convenient to use the auxiliary spring to drive the limit block to move, prevent the limit block from being fixed in position and causing damage to the rotating shaft, while achieving buffering and shock absorption work.

[0018] Optionally, in the above-mentioned wire unwinding device with an alarm device applied to a coreless wire winding machine, the wear-resistant blocks are evenly and equidistantly distributed on the inner side of the limit block, and adsorption magnets are symmetrically distributed on both sides of the limit block, and the adsorption magnets are adsorbed to each other with the adsorption magnets on the other side.

[0019] Through the above technical solution, it is convenient to use the adsorption magnet to strengthen the fixing effect of the limit block and avoid the limit block from shaking.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] By arranging a fixed block and a limit block on the left side of the bracket body, when the rotating shaft is about to shake, it abuts against and contacts the limit block, and the auxiliary spring and shock absorber on the rear side of the limit block cooperate to reduce the shaking amplitude of the rotating shaft, thereby achieving the purpose of protecting the rotating shaft and extending the service life of the rotating shaft;

[0022] By arranging a driven rod and an auxiliary block on the outside of the rotating shaft, the auxiliary block is driven to rotate by the driven rod when the rotating shaft rotates. Once the tungsten wire disk idles, the rotation speed of the rotating shaft is accelerated, so that the auxiliary block touches the sensor and an emergency alarm is issued, so that an alarm will be issued in the event of idling or overload, and the alarm is highly accurate without false alarms.

[0030] A driven rod 7 is also connected to the outside of the rotating shaft 2, and the driven rod 7 drives the auxiliary block 9 to move to improve the effect. An elastic rope 8 is connected to the outside of the driven rod 7, and the auxiliary block 9 is connected to the outside of the elastic rope 8. The auxiliary block 9 cooperates with the sensor 6 to issue an alarm when the rotating shaft 2 is detected to be shaking or rotating too fast. A sensor 6 is provided on the other side of the auxiliary block 9, and the outside of the sensor 6 is connected to the support block 5.

[0031] See the attached drawings in the specification Figure 1-4 The connection method between the bracket body 1 and the fixed block 3 is hot-melt connection. The fixed block 3 is an "L"-shaped structure. The fixed block 3 and the auxiliary spring 10 are installed in an integrated manner. The fixed block 3 is fixed by the bracket body 1, so that the fixed block 3 cooperates with the auxiliary spring 10 to perform subsequent limiting work.

[0032] See the attached drawings in the specification Figure 1-4 The support block 5 is installed integrally with the bracket body 1, the center of the support block 5 coincides with the center of the sensor 6, the center of the sensor 6 and the center of the auxiliary block 9 are on the same horizontal line, and the support block 5 is used to limit the sensor 6 to facilitate the sensing work of the auxiliary block 9.

[0033] See the attached drawings in the specification Figure 1-4 The driven rod 7 is symmetrically distributed on both sides of the rotating shaft 2. The driven rod 7 rotates integrally with the rotating shaft 2. The driven rod 7 forms an integrated rotating structure with the auxiliary block 9 through the elastic rope 8. The elastic rope 8 is used to drive the auxiliary block 9 to move, so that when the rotating shaft 2 speeds up or shakes, the auxiliary block 9 hits the top of the sensor 6.

[0034] See the attached drawings in the specification Figure 1-4 The auxiliary spring 10 and the limit block 11 are installed in an integrated manner. The limit block 11 has a semicircular structure. The limit blocks 11 are symmetrically distributed on both sides of the center of the rotating shaft 2.

The adsorption magnets 13 are used to strengthen the fixing effect of the limit block 11 to prevent the limit block 11 from shaking.

[0036] Working principle: When in use, first, when releasing the wire, the rotating shaft 2 drives the tungsten wire disc 4 to rotate, so as to release the wire. When the rotating shaft 2 rotates stably, it drives the auxiliary block 9 to rotate through the support block 5 and the elastic rope 8, so that the auxiliary block 9 rotates stably inside the sensor 6. When the rotating shaft 2 speeds up or shakes, the centrifugal force of its rotation increases, so that the elastic rope 8 is extended, so that the auxiliary block 9 hits the top of the sensor 6, thereby triggering the alarm;

[0037] As mentioned above, when the rotating shaft 2 rotates smoothly, it does not contact the limit block 11. When the rotating shaft 2 shakes, it hits the top of the limit block 11. The auxiliary spring 10 on the other side of the rear limit block 11 cooperates with the shock absorber to buffer the limit block 11 to prevent the rotating shaft 2 from vibrating too strongly. At the same time, the adsorption magnets 13 adsorb each other, so that the limit block 11 quickly resets, and the above work is repeated.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
