Description

Technical Field

[0001] This utility model relates to the field of coil feeding technology, and in particular to a feeding mechanism. Background Technology

[0002] In the current flexible printed circuit board industry, the roll feeding method involves mounting one end of a feeding shaft on a bearing and then installing a drive motor at the other end to maintain the position of the feeding shaft. During feeding, the roll of material is placed on the feeding shaft, and the material is released by rolling. However, with the above structure, the feeding angle is fixed because both ends of the feeding shaft are restricted, which cannot adapt well to various production feeding situations. Installing a drive motor at one end of the feeding shaft is to avoid the problem of the feeding shaft rotating due to the lack of bearing restraint during material pulling. However, installing a drive motor increases the overall structural footprint and cost.

[0003] The technical problem to be solved by this application is: to design a feeding mechanism that can adapt to multi-angle feeding and has a simple structure. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: a feeding mechanism, including a feeding shaft and a rotating seat connected to the feeding shaft. The bottom of the rotating seat is provided with a mounting plate rotatably connected thereto. The mounting plate is provided with a limiting block for limiting the rotation angle of the rotating seat. The interior of the rotating seat is provided with an anti-rotation mechanism to prevent the feeding shaft from rotating during feeding.

[0006] In some embodiments, the feeding shaft and the rotating seat are rotatably coupled, the rotating seat is provided with a first bearing, and one end of the feeding shaft is rotatably connected to the first bearing.

[0007] In some embodiments, the positioning device includes a mounting base and a fixed base disposed on the mounting base. The fixed base is provided with a U-shaped groove, and a spring universal ball is provided inside the U-shaped groove for positioning the other end of the feeding shaft. When the feeding shaft is discharging material, the other end of the feeding shaft is in a limiting engagement with the U-shaped groove.

[0008] In some implementations, the feeding shaft is also provided with a handle at one end near the positioning device.

[0009] In some embodiments, the limiting block is provided with a stop connected thereto, the stop being made of a magnet.

[0010] In some embodiments, the rotating seat has a through hole corresponding to the first bearing, and the feeding shaft is rotatably connected to the first bearing and rotates with the through hole.

[0011] In some embodiments, the anti-rotation mechanism includes a spring plate connected to the rotating seat, a compression spring connected to the bottom of the spring plate, and a resistance block connected to the other end of the compression spring.

[0012] In some embodiments, the resistance block is located above the through hole and extends into the interior of the through hole. The resistance block and the rotating seat are in a limiting sliding fit. After the feeding shaft and the through hole are rotated, the resistance block and the feeding shaft abut against each other.

[0013] In some embodiments, the mounting plate is provided with a rotating shaft connected thereto, and the rotating seat and the rotating shaft are in a limiting rotational fit.

[0014] This utility model has the following technical effects: by connecting one end of the feeding shaft to the rotating seat, and the rotating seat is rotatably connected to the mounting plate, the feeding position of the feeding shaft can be changed synchronously by rotating the rotating seat, thus adapting to multi-angle feeding.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a feeding mechanism, including a feeding shaft 1 and a rotating seat 2 connected to the feeding shaft 1. A mounting plate 3 is provided at the bottom of the rotating seat 2 and is rotatably connected thereto. The feeding shaft 1 and the rotating seat 2 are rotatably connected. A first bearing 20 is provided inside the rotating seat 2. One end of the feeding shaft 1 is rotatably connected to the rotating seat 2 by limiting rotatable connection with the first bearing 20. In this way, the position of the feeding shaft 1 can be changed by rotating the rotating seat 2 on the mounting plate 3, thereby changing the feeding angle and realizing multi-angle feeding at different positions.

[0022] To ensure the stability of feeding after the feeding shaft 1 changes position, a limiting block 30 is provided on the mounting plate 3. The limiting block 30 is connected to a stop block 31, which is made of magnet. The rotating seat 2 is also made of metal. So when the rotating seat 2 is rotated to change the position of the feeding shaft 1, until one side of the rotating seat 2 is in contact with the stop block 31, the stop block 31, being made of magnet, will attract the rotating seat 2 and position it, thereby achieving the function of positioning the feeding shaft 1 and ensuring the stability of feeding after the feeding shaft 1 changes position.

[0023] To ensure the stability of the other end of the feeding shaft 1, a positioning device 5 is also included. The positioning device 5 includes a mounting base 50 and a fixed base 51 mounted on the mounting base 50. A U-shaped groove 52 is provided on the fixed base 51, and a spring-loaded universal ball 53 is installed inside the U-shaped groove 52. When feeding material using the feeding shaft 1, the rotating base 2 is first rotated to disengage the feeding shaft 1 from the U-shaped groove 52. Then, the coiled material is placed on the feeding shaft 1. Finally, the rotating base 2 is pushed back, causing the feeding shaft 1 to re-engage in the U-shaped groove 52 for positioning. Because of the U-shaped groove... The U-shaped groove 52 is equipped with a spring universal ball 53. When the feeding shaft 1 is pushed back into the U-shaped groove 52, the spring universal ball 53 will be pressed down. When the feeding shaft 1 is already in the U-shaped groove 52, the spring universal ball 53 will spring back and reset, thereby limiting one end of the feeding shaft 1 in the U-shaped groove 52 and fixing the other end of the feeding shaft 1. In order to facilitate the rotation of the rotating seat 2, a handle 10 is also provided at the end of the feeding shaft 1 near the positioning device 5, so that the feeding shaft 1 can be pushed by the handle 10 to drive the rotating seat 2 to rotate.

[0024] To prevent the feeding shaft 1 from rotating due to inertia during material feeding, thus avoiding overfeeding, an anti-rotation mechanism 4 is provided inside the rotating seat 2. The rotating seat 2 has a through hole 21 corresponding to the first bearing 20. When the feeding shaft 1 is rotatably connected to the first bearing 20, it also rotatably engages with the through hole 21. The anti-rotation mechanism 4 includes a spring plate 40 connected to the rotating seat 2, a compression spring 41 connected to the bottom of the spring plate 40, and a resistance block 42 connected to the other end of the compression spring 41. The resistance block 42 is located above the through hole 21 and extends into the interior of the through hole 21. The resistance block 42 and the rotating seat 2 are in a limiting sliding fit. So when the feeding shaft 1 passes through the through hole 21, it will push the resistance block 42 upward. Since the resistance block 42 is connected to the upper part of the compression spring 41, the resistance block 42 will be subjected to the downward pressure of the compression spring 41 and thus come into contact with the feeding shaft 1. This increases the frictional resistance between the feeding shaft 1 and the resistance block 42. As a result, when the feeding shaft 1 feeds material, it will not rotate due to inertia, and there will be no problem of excessive feeding.

[0025] In order to enable the rotating seat 2 to rotate on the mounting plate 3, a rotating shaft 30 connected to it is provided on the mounting plate 3, wherein the rotating seat 2 and the rotating shaft 30 are in a limited rotational fit, thereby realizing the rotational connection of the rotating seat 2 on the mounting plate 3.

[0026] The working principle of this utility model is as follows: By connecting one end of the feeding shaft 1 to the rotating seat 2, and the rotating seat 2 is rotatably connected to the mounting plate 3, the feeding position of the feeding shaft 1 can be changed synchronously by rotating the rotating seat 2, thereby adapting to multi-angle feeding. Furthermore, an anti-rotation mechanism 4 is provided inside the rotating seat 2, which can prevent the feeding shaft 1 from rotating due to inertia during feeding. The overall structure is simple and occupies little space.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
