DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4 As shown, an automatic feeding structure of a round rod machine provided by an embodiment of the utility model includes a feeding box 1, a pushing area 101 is arranged at the rear end of the feeding box 1, a conveying area 102 is arranged at the front end of the feeding box 1, a limiting mechanism 4 is arranged in the conveying area 102, a feeding table 2 is fixedly connected to the feeding box 1 located at the rear side of the pushing area 101, a plurality of transmission shafts 3 that need to be conveyed are placed on the feeding table 2, and a pushing mechanism 5 is fixedly installed on the feeding box 1 located at the front side of the pushing area 101.

[0024] Furthermore, the unloading surface of the unloading platform 2 is an inclined surface, and the discharge port of the unloading platform 2 corresponds to the pushing area 101 .

[0025] In the present application, the raw material of the transmission shaft 3 to be transported can be transported to the pushing area 101 through the discharge port of the unloading platform 2 so that the pushing mechanism 5 can push it.

[0026] Furthermore, the limiting mechanism 4 includes two limiting rods 402 and a bidirectional screw rod 401, the bidirectional screw rod 401 is located between the two limiting rods 402, the limiting rod 402 is fixedly installed on the feeding box 1, the bidirectional screw rod 401 is rotatably connected to the feeding box 1, both ends of the bidirectional screw rod 401 are threadedly connected with screw rod sleeves 403, a first motor 404 is fixedly installed on the outer wall of the feeding box 1, the output shaft of the first motor 404 is fixedly connected to one end of the bidirectional screw rod 401, limiting plates 405 are arranged on both sides of the conveying area 102, each limiting plate 405 is fixedly sleeved on each screw rod sleeve 403, both ends of the limiting plate 405 slide along the outer surface of the limiting rod 402, and an arc-shaped guide portion 4051 is provided on the lower surface of the limiting plate 405 close to the pushing area 101.

[0027] In the present application, the bidirectional screw 401 is driven to rotate by the first motor 404, thereby driving the screw sleeves 403 at both ends to move simultaneously in the direction of approaching or moving away from each other. The movement of the screw sleeve 403 will synchronously drive the two limit plates 405 to move. Under the limitation of the two limit plates 405, the transmission shaft 3 of different diameters can be limited in the conveying area 102, so that the transmission shaft 3 can maintain linear motion in the conveying area 102, so as to increase the subsequent feeding speed of the transmission shaft 3, thereby improving the processing efficiency. The setting of the arc guide part 4051 is conducive to the transmission shaft raw material to smoothly enter the conveying area 102 under the guidance of the arc guide part 4051.

[0028] Furthermore, the pushing mechanism 5 includes a fixed plate 501, which is fixedly installed on the feeding box 1. The upper outer end of the fixed plate 501 is fixedly connected to the machine base 502, and the second motor 503 is fixedly installed on the machine base 502. The upper inner end of the fixed plate 501 is fixedly connected to the fixed rod 504. The output shaft of the second motor 503 passes through the fixed rod 504 and is fixedly connected to the rotating rod 505 at the left end. The rotating rod 505 is located on the inner side of the fixed rod 504. The rotating rod 505 is fixedly connected to a fixed shaft 506 at one end away from the fixed rod 504. The outer surface of the fixed shaft 506 is rotatably connected to a first linkage rod 507, and the first linkage rod 507 is fixedly connected to a pushing rod 508 at one end away from the rotating rod 505.

[0029] In the present application, after the transmission shaft 3 slides through the unloading table 2 and falls into the pushing area 101, the rotating rod 505 is driven to rotate by the second motor 503. The rotation of the rotating rod 505 will drive the first linkage rod 507 rotatably connected to the fixed shaft 506 to move toward the direction close to the conveying area 102 until the transmission shaft 3 is pushed from the pushing area 101 to the conveying area 102. When the pushing is completed, the pushing rod 508 moves in an arc in the opposite direction under the drive of the first linkage rod 507 until the pushing rod 508 moves to its initial position.

[0030] Furthermore, a slide groove 5071 is opened on the front side of the first linkage rod 507, and the inner side of the first linkage rod 507 moves along the outer wall of the feeding box 1. The right end of the fixed rod 504 is rotatably connected to the second linkage rod 509, and the inner side of the second linkage rod 509 away from one end of the fixed rod 504 is rotatably connected to the slider 510, and the slider 510 slides along the inner wall of the slide groove 5071.

[0031] In the present application, under the movement of the first linkage rod 507, the second linkage rod 509 rotates under the limitation of the slide groove 5071, and the slider 510 supports and limits the first linkage rod 507, so that the first linkage rod 507 moves within a certain plane.

[0032] The working principle of this utility model:

[0033] In the present application, the first motor 404 is first started to drive the bidirectional screw 401 to rotate, thereby driving the two limit plates 405 fixedly connected to the screw sleeve 403 to move towards or away from each other at the same time, until the distance between the two limit plates 405 is adjusted to a distance suitable for the diameter of the transmission shaft 3 raw material, and then a number of transmission shaft 3 raw materials that need to be transported are placed on the unloading table 2. Under the action of gravity, the transmission shaft 3 raw materials will slide into the pushing area 101, and then the second motor 503 is started to rotate the rotating rod 505. Under the rotation of the fixed shaft 506, it will synchronously drive the first linkage rod 507 towards the conveying The first linkage rod 507 moves in the direction of the pushing zone 102 until the raw material of the transmission shaft 3 is pushed from the pushing zone 101 to the conveying zone 102. When the pushing is completed, the pushing rod 508 fixedly connected to the first linkage rod 507 will be driven to make an arc-shaped reverse motion under the continuous drive of the second motor 503 until the pushing rod 508 moves to the initial position. During this process, the second linkage rod 509 rotates under the limit of the slide groove 5071, and the slider 510 supports and limits the first linkage rod 507, so that the first linkage rod 507 moves in a determined plane. Repeat the above steps to continuously convey the raw material of the transmission shaft 3.

[0034] To sum up: this kind of automatic feeding structure of the round rod machine, through the setting of the limiting mechanism 4, is convenient for adjusting the distance between the two limiting plates 405, so as to adapt to the transportation of transmission shafts 3 of different diameters, and at the same time, it can also ensure that the transmission shaft 3 during the transportation process maintains a straight line in the conveying area 102, thereby improving the subsequent loading accuracy and thus improving the processing efficiency; through the setting of the pushing mechanism 5, it is helpful to convey the transmission shaft 3 that slides into the pushing area 101, which not only reduces the tedious process of manual feeding, but also greatly improves the feeding efficiency.
