Description

Technical Field

[0001] The utility model relates to the technical field of bar loading machines, in particular to a full-automatic bar loading machine. Background Art

[0002] An automatic bar feeder refers to a feeding machine that cooperates with equipment capable of continuously and circularly processing bar materials to achieve automatic feeding, thereby improving the processing efficiency and automation degree of the equipment.

[0003] In the process of loading bars by a common bar loading machine, when loading a large number of bars at one time, the bars cannot pass smoothly, and it is easy to have a problem of accumulation. Moreover, there are large differences in the diameter or length of the bars, which may cause a problem of jamming during the conveying process. This will not only reduce the overall production efficiency, but also may cause damage to the loading machine itself.

[0004] Therefore, for the above-mentioned bar loading machine, in the process of loading bars, it may cause problems of jamming or accumulation during the conveying process, which will not only reduce the overall production efficiency, but also may cause damage to the loading machine itself. It is urgently needed to be solved to improve the use scenario of the bar loading machine. Summary of the Utility Model

[0005] In order to overcome the problems of jamming or accumulation that occur during the conveying process when a common bar loading machine loads bars.

[0006] The technical solution of the utility model is as follows: a full-automatic bar loading machine, including a chassis. The front surface of the chassis is fixedly provided with a mounting frame. The rear end surface of the chassis is fixedly welded with a support frame. The upper end surface of the chassis is fixedly provided with a plurality of guiding plates. A placing frame is connected to the plurality of guiding plates through a rotating shaft. An electric push rod I is installed at the middle position inside the support frame. The top of the output end of the electric push rod I is fixedly connected to the placing frame. Two fixing rods are installed in the mounting holes of the plurality of guiding plates through bearings. A plurality of rotating rollers are fixedly provided on the surface of the fixing rods. Two pushing plates are fixedly provided on the surface of the rotating rollers. The pushing plates are symmetrically arranged up and down. Two sliding rails are fixedly provided on the right end surface of the guiding plates. A slider is slidably connected to the outside of the two sliding rails. An electric push rod II is fixedly provided on the right end surface of the slider. The output end of the electric push rod II is fixedly connected to a bar pushing block. The height of the front end of the top surface of the bar pushing block is lower than that of the rear end. A plurality of limiting rings are fixedly provided on the upper end surface of the chassis near the mounting frame side. One end of a conveying roller is movably installed on the upper end surface of the chassis near the mounting frame side through a mounting member.

[0007] Preferably, the staff only needs to place the bar on the placement rack to complete the feeding work. The inclination angle of the placement rack is controlled by the first electric push rod to control the rolling speed of the bar. The bar will roll onto the guide plate. The surface of the guide plate is serrated. The bar will stop rolling at the high ridge of the serrations. The rotating roller is driven to rotate, and the rotating roller drives the push plate to rotate. The push plate will rotate around the rotating roller, thereby helping the bar to cross the high ridge. The bar will roll to the high ridge of the next guide plate and stop rolling, and the push plate will help the bar cross the high ridge again. At this time, the bar has been adjusted twice in position to ensure that the bar can correctly enter the subsequent processing process. At the same time, the push plate drives one bar to cross the high ridge each time, enabling the bars to be continuously fed in sequence, effectively solving the problem that the accumulation of bars affects production and processing. The bar will roll to the third high ridge of the guide plate and stop rolling. At the same time, multiple second electric push rods are started, so that multiple bar push blocks move upward at the same time, driving the bar to move upward, thereby helping the bar cross the third high ridge. The multiple bar push blocks need to maintain the same height to avoid affecting the conveying quality of the bar. The bar will roll into the limit ring and onto the upper surface of the conveying roller. The limit ring guides and positions the bar. The conveying roller is driven to rotate to transport the bar. The center of the conveying roller is concave inward, making the bar more stable during transportation.

[0008] Preferably, two first motors are installed at the position near the front end of the top of the chassis. The output end of the first motor is fixedly provided with a first driving gear. The right end surface of the fixed rod is fixedly provided with a driven gear. Starting the first motor can drive the first driving gear to rotate.

[0009] Preferably, one end of a first chain is meshed and connected with the first driving gear, and the other end of the first chain is meshed and connected with the driven gear. The rotation of the first driving gear can drive the first chain to rotate, thereby driving the driven gear to rotate. The driven gear will drive the fixed rod to rotate, thereby driving the rotating roller and the push plate to rotate, helping the bar cross the high ridge.

The second driving gear will drive the driven rack and the second electric push rod to move back and forth, thereby adjusting the position of the bar push block. The slide rail and the slider enable the second electric push rod to have good stability during movement.

[0012] Preferably, a support rod is fixedly arranged on the upper end surface of the mounting frame. The upper end surface of the support rod is fixedly provided with a mounting plate. The upper end surface of the mounting plate is fixedly provided with a second motor. The output end of the second motor is fixedly connected to the front side of the rightmost conveying roller. Tooth grooves are formed on the surface of the rotating shaft of the conveying roller. One end of a second tooth chain is meshed with the rotating shaft of the rightmost conveying roller. The other end of the second tooth chain is meshed with the rotating shaft of the rightmost conveying roller. The second tooth chain is meshed with the rotating shafts of multiple conveying rollers. Starting the second motor drives the second tooth chain to rotate, and the second tooth chain drives multiple conveying rollers to rotate, thereby conveying the bars on the conveying rollers.

[0013] Preferably, a plurality of retaining rods are fixedly arranged on the upper end surface of the side of the placing frame away from the bottom frame. A placing strip is fixedly arranged on the upper end surface of the placing frame. A rubber pad is sleeved on the upper end surface of the placing strip. The arrangement of the retaining rods can prevent the bars from slipping off from the retaining rods. Placing the bars on the placing strip can complete the feeding work, thereby improving the feeding work efficiency and reducing the workload of the staff. A rubber pad is sleeved on the upper end surface of the placing strip, so that the bars will roll and move on the placing strip, reducing the occurrence of sliding movement, greatly reducing the friction force, well protecting the surface of the bars, and having a good buffering effect, not only reducing the impact on the device, but also protecting the bars.

[0014] The beneficial effects of the present utility model:

[0015] 1. The staff only needs to place the bars on the placing frame to complete the feeding work. By controlling the inclination angle of the placing frame through the first electric push rod, the rolling speed of the bars is controlled. The bars will roll onto the guiding plate.
