The automatic counting and feeding mechanism automatically completes the effect of a single drilling bit falling in a queue by rotating the feeding wheel, can effectively realize the counting into the temporary storage slot, and pushes a fixed number of drilling bits into the inner box by pushing the feeding push block, thereby avoiding the problem of errors and omissions during manual boxing.

Description

Technical Field

[0001] The invention relates to the field of automated packaging, and in particular to an automatic counting and feeding mechanism for drill bit boxing. Background Art

[0002] Traditional drill bit packaging is usually done by manpower. Although some semi-automatic equipment has been added today to improve packaging efficiency to a certain extent, it still has defects compared to fully unmanned automated packaging: the process of packing drill bits into inner boxes has a low degree of automation and is mainly done by manual counting and packing. Since the blade of the drill bit is relatively sharp, there is still a risk of injury to the worker during box packing. In addition, the number of drill bits packed in each box depends on manual counting, which has a certain error rate and reduces the consistency of the product. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and proposes an automatic counting and feeding mechanism for drill bit boxing, comprising a drill bit storage box, a feeding wheel, a temporary storage groove and a feeding cylinder. The side surface of the feeding wheel is evenly provided with drill bit grooves along the circumference, and the drill bit groove is a semicircular groove that can only accommodate one drill bit. The feeding wheel is installed at the lower wall of the drill bit storage box. The lower wall of the drill bit storage box is inclined downward and has a covering wall extending in a clockwise direction. The end of the covering wall is guided to the temporary storage groove through a blanking inclined plate. An inner box is placed on one side of the temporary storage groove, and a feeding push block is provided on the other side; the feeding cylinder is arranged below the temporary storage groove, and the guide rod of the feeding cylinder is horizontally and synchronously connected with the feeding push block.

[0004] Furthermore, the automatic counting and feeding mechanism also includes an inner box alignment floating head, which is installed on the working panel of the packaging machine through a floating head spring. A sinking floating head groove that cooperates with the inner box alignment floating head is provided on the working panel of the packaging machine, and the sinking floating head groove is arranged below the position of the inner box.

[0005] Furthermore, the upper surface of the inner box alignment floating head is thumb-shaped.

[0006] Furthermore, the upper surface of the inner box alignment floating head is divided into two sections, the section close to the temporary storage groove is counterclockwise inclined, and the section away from the temporary storage groove is horizontal.

[0007] Furthermore, the drill bit storage box is provided with an inclined primary inclined plate, and the primary inclined plate is inclined clockwise.

[0008] Furthermore, the feeding wheel is connected to a wheel servo motor, and the wheel servo motor rotates counterclockwise.

[0009] Furthermore, a laser counter (not shown in the figure) is provided in the temporary storage tank.

[0010] Furthermore, the side wall of the drill storage box is an adjustment side plate installed by a handwheel bolt, and the adjustment side plate can be moved inward and outward by loosening or tightening the handwheel bolt to adapt to drill bits of different lengths.

[0011] Beneficial effect: In the present invention, the automatic counting and feeding mechanism automatically completes the effect of a single drill bit falling in a queue through the rotation of the feeding wheel, can effectively realize the counting into the temporary storage slot, and pushes a fixed number of drill bits into the inner box through the push of the feeding push block, avoiding the problem of errors and omissions during manual box loading; the inner box can be kept in a horizontal state by aligning the floating head to facilitate the loading of the drill bits.
