Description

Feeding mechanism of short cylindrical material

Technical field

The invention relates to a feeding device for small objects, in particular to a feeding mechanism for short cylindrical materials, belonging to the technical field of loading equipment.

Background technique

The traditional brush for calligraphy, the brush for painting, and the foundation for women's makeup are all short cylindrical. For example, the brush is usually used as the raw material for the hair of the wolf, the sheep and the chest of the poultry. After sorting, a plurality of vellus hair bundles are bundled at the root and glued together, the root is implanted at one end of the sheath sleeve, and the other end of the sheath sleeve is inserted at the end of the sheath.

Although modern industry is very developed, for traditional stationery such as writing brushes, because of its unique personality and style, it is still mainly produced by experienced personnel in hand workshops, and has not entered industrial manufacturing. After receiving the order, assemble the corresponding pen and pen, and print the text or label according to the customer's needs. In recent years, with the growth of the brush market, pure hand-made has shown drawbacks, mainly because of low work efficiency, high labor intensity, and the salary of skilled workers is increasing year by year. Once the delivery time conflicts with the busyness of the farm, festivals, etc., It is difficult to deliver on time.

When the pen tip is assembled with the pen holder, it needs to be dispensed in the pen tip sleeve, and the pen holder needs to be printed, and the worker's long-term contact with the glue and the ink is easy to damage health. Therefore, the assembly of the pen tip and the pen holder is industrialized by using equipment, which not only maintains the traditional style of the product, but also improves the work efficiency, reduces the labor intensity of the worker, and ensures the consistency of the finished product.

Since the pen holder is long, it can be placed in the pen hopper by the operator in advance; the one end of the pen head is a bristles and the other end is a sleeve, and the overall size is relatively short, which is inconvenient for the operator to pre-finish, numerous The pen tip is dumped in the large pen hopper, which is bound to be disordered. The premise of industrial assembly is to take out a lot of messy and disorderly pens one by one from the hopper, and send them in a uniform direction on the production line. A short cylindrical material similar in shape to the tip of the pen encounters the same problem during the loading process.

Summary of the invention

The object of the present invention is to overcome the problems in the prior art and to provide a feeding mechanism for short cylindrical materials, which can smoothly take out the disordered short cylindrical materials one by one from the hopper and correct the direction.

In order to solve the above technical problem, the feeding mechanism of the short cylindrical material of the present invention comprises a hopper supported on the frame, and two rows of parallel chains are arranged on the right side of the hopper, and one pair of corresponding materials are arranged on the two chains.

The upper probe and the lower probe can not only detect the presence or absence of the short cylindrical material, but also judge the positive and negative directions of the short cylindrical material. If the orientation of the short cylindrical material is opposite, the slider of the reversing lifting rodless cylinder is lowered to make the rotary cylinder and the reversing clamp The claw cylinder and the reversing jaw are lowered until the reversing jaw is located on both sides of the short cylindrical material, and then the reversing jaw cylinder acts to clamp the short cylindrical material around the reversing jaw, and then the reversing lifting rodless cylinder When the slider rises, the short cylindrical material is lifted off the material supporting V-shaped frame, and then the rotating cylinder moves to drive the short cylindrical material to rotate 180°, then the slider of the reversing lifting rodless cylinder is lowered to reposition the short cylindrical material in the material supporting V-shaped frame.
