Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolt processing, in particular to an automatic tooth bar unloading device. Background Art
[0002] When processing tooth bars, it is necessary to put the tooth bar blank into the thread rolling machine, and use the thread rolling plate to roll the thread on the end of the tooth bar. At present, the tooth bars are piled up in the discharge bin. During the discharge process of the tooth bars, the tooth bars may be squeezed against each other, and the discharge port may be blocked, which will interrupt the automatic discharge of the tooth bars, affect the subsequent work of the thread rolling plate, and reduce production efficiency. After the discharge port is blocked, the tooth bar may tilt. After the tilted tooth bar is rolled, the thread position on the tooth bar will also be offset, making the tooth bar quality non-compliant. Utility Model Content
[0003] In order to solve the above problems, the utility model provides an automatic tooth stick unloading device, which can quickly complete the unloading of tooth sticks and the unloading position of the tooth sticks is accurate.
[0004] To this end, the technical solution of the utility model is: an automatic feeding device for tooth sticks, comprising a feeding bin, in which a continuous S-shaped feeding channel is provided; a discharge port is provided on the side of the feeding bin near the bottom, and a feeding block that can swing toward the discharge port is provided inside the discharge port, and a first arc-shaped groove is provided on the upper side of the feeding block, and the first arc-shaped groove faces the discharge port or away from the discharge port; a feeding chute is provided on the outer side of the discharge port, and the lowest point of the feeding chute is connected to an arc-shaped support block; a feeding push rod is provided on the side of the arc-shaped support block, and the feeding push rod extends toward one side of the arc-shaped support block.
[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: the unloading channel is provided with an opening toward the discharge port, and the unloading block is rotatably installed in the opening; it also includes an electric push rod, which is rotatably installed at the bottom of the unloading bin, and the output end of the electric push rod is rotatably connected to the bottom of the unloading block, and the electric push rod can drive the unloading block to swing toward one side of the discharge port.
[0006] On the basis of the above solution and as a preferred solution of the above solution: the inner diameter of the first arc-shaped groove of the blanking block matches the outer diameter of the tooth bar.
[0007] On the basis of the above solution and as a preferred solution of the above solution: a second arc-shaped groove is provided above the arc-shaped support block, and the inner diameter of the second arc-shaped groove matches the outer diameter of the tooth stick.
[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: a feed port is provided above the feed bin, and the feed port corresponds to the entrance position of the feed channel.
[0009] When in use, the tooth stick is put into the feeding port above the feeding bin, and the tooth stick rolls along the S-shaped feeding channel. The height of the S-shaped feeding channel is controlled so that only a single row of tooth sticks can roll, and the tooth sticks roll to the bottom. In the initial state, the first arc groove of the feeding block is tilted away from the discharge port, so that the lowest tooth stick rolls into the first arc groove, and the tooth stick can also be prevented from being discharged; when the tooth stick is discharged, the electric push rod drives the feeding block to swing toward the discharge port, so that the tooth stick in the first arc groove is pushed into the feeding chute, and falls into the second arc groove of the arc support block along the feeding chute; then the feeding push rod is started to push the tooth stick in the second arc groove into the thread rolling plate. At the same time, when the feeding block swings toward the discharge port, it can just block the second tooth stick below; then the electric push rod drives the feeding block to swing away from the discharge port and reset, and then the second tooth stick below rolls into the first arc groove, waiting for the next feeding, and the tooth sticks are sent out one by one by the feeding block, and there will be no blockage problem.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: a continuous S-shaped feeding channel is arranged in the feeding bin, so that the tooth sticks roll in a single row in the feeding bin and are sent out one by one by the feeding block without clogging problems, thereby ensuring smooth and automatic feeding of the tooth sticks. After feeding, the tooth sticks fall into the arc-shaped support block and are pushed out by the feeding push rod, thereby ensuring that the tooth sticks fall into the thread rolling plate one by one for thread rolling, thereby ensuring the working efficiency of thread rolling.
