TECHNICAL FIELD

[0001] The utility model relates to the packaging field especially a kind of packing material bottle cap blanking mechanism. BACKGROUND

[0002] In cosmetic packing material production, bottle cap as supporting product needs to be produced with packing material in production line, and the timed and quantitative blanking of bottle cap is necessary link of production, and currently, the blanking mechanism of bottle cap is complex in structure, large in size, and not suitable for small-scale packing material production line. SUMMARY

[0003] The utility model provides a kind of packing material bottle cap blanking mechanism, simple structure, small size.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: a kind of packing material bottle cap blanking mechanism, including material box, the baffle being arranged at the bottom of material box, the swing lever being pivotally connected at one side of material box, the driving rod being cooperated with swing lever and the cylinder driving driving rod;The upper end of the material box is provided with inlet, and the lower end of the material box is provided with outlet;Half of the baffle forms shielding part and is arranged at outlet, and the other half of the baffle forms connecting part and extends out the back side of material box and is hinged with material box by hinged seat;The swing lever is hinged with material box by pivot, and one end of swing lever is provided with counterweight, and the other end of swing lever is provided with first protruding column, and C-shaped connecting rod is arranged between the connecting part of baffle and swing lever, one end of C-shaped connecting rod is fixedly connected with connecting part, and the other end of C-shaped connecting rod is cooperated with first protruding column;The back side of the material box is provided with mounting plate, and the cylinder is arranged on mounting plate, and the cylinder drives one end of driving rod by transmission shaft, and the other end of driving rod is provided with second protruding column cooperated with swing lever.The utility model principle: when the cylinder contracts, the cylinder drives driving rod to rotate upwards by transmission shaft, and second protruding column leaves swing lever, at this time, swing lever is swung upwards at one end counterweight, and first protruding column acts on C-shaped connecting rod, and C-shaped connecting rod drives baffle to overturn around hinged seat, and the lower end outlet of material box is opened to carry out blanking;When the cylinder extends, the cylinder drives driving rod to rotate downwards by transmission shaft, and second protruding column acts on swing lever, and the force is greater than the counterweight of swing lever, at this time, swing lever is swung downwards, and first protruding column leaves C-shaped connecting rod, and because the counterweight of C-shaped connecting rod and connecting part is greater than shielding part, baffle cannot overturn, and shielding part closes the lower end outlet of material box.

[0005] As an improvement, the first protruding column is arranged below the end of C-shaped connecting rod, and the second protruding column is arranged above the swing lever.

[0006] As an improvement, the mounting plate is horizontally set, one end of the mounting plate is welded to the material box, the mounting plate is provided with a bearing seat, the drive shaft passes through the bearing seat, the cylinder is connected to one end of the drive shaft through a connecting rod, and the other end of the drive shaft is connected to the drive rod.

[0007] The beneficial effects of this utility model compared with the prior art are:

[0008] The baffle is opened by using a cylinder, drive rod, swing rod and C-shaped connecting rod, and the baffle is closed by using the counterweight of the C-shaped connecting rod and the connecting part. The overall structure is simple, low cost and small size, and it is especially suitable for use in small-scale packaging material production lines. Attached Figure Description

[0009] Fig. 1 This is a perspective view of the present utility model.

[0010] Fig. 2 This is a side view of the present invention.

[0011] Fig. 3 This is a top view of the present invention. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figs. 1 to 3As shown, a bottle cap feeding mechanism for packaging materials includes a material box 1, a baffle 2 located at the bottom of the material box 1, a swing rod 3 pivotally connected to one side of the material box 1, a drive rod 4 cooperating with the swing rod 3, and a cylinder 8 driving the drive rod 4. The material box 1 is used to store bottle caps, with an inlet at the upper end and an outlet at the lower end. One half of the baffle 2 forms a blocking part 21 located at the outlet, and the other half forms a connecting part 22 extending from the rear side of the material box 1 and hinged to the material box 1 via a hinge seat. The blocking part 21 is flipped by the hinge seat to open and close the outlet. The middle part of the swing rod 3 is pivotally connected to the material box 1 via a pivot shaft. One end of the swing rod 3 is provided with a counterweight 31, and the other end of the swing rod 3 is provided with a first protrusion 32. When no external force is applied, the end of the swing rod 3 with the counterweight 31 faces downwards, and the end with the first protrusion 32 faces upwards. A C-shaped connecting rod 6 is provided between the connecting part 22 of the baffle 2 and the swing rod 3. One end of the C-shaped connecting rod 6 is fixedly connected to the connecting part 22, and the other end of the C-shaped connecting rod 6 cooperates with the first protrusion 32, which is located below the end of the C-shaped connecting rod 6. A mounting plate 9 is provided on the rear side of the material box 1. The mounting plate 9 is horizontally set, and one end of the mounting plate 9 is welded to the material box 1. The cylinder 8 is mounted on the mounting plate 9. The cylinder body of the cylinder 8 is hinged. The telescopic rod of the cylinder 8 is connected to one end of the transmission shaft 7 through a connecting rod. The other end of the transmission shaft 7 is connected to one end of the drive rod 4. The cylinder 8 drives one end of the drive rod 4 through the transmission shaft 7. A bearing seat is provided on the mounting plate 9, and the transmission shaft 7 passes through the bearing seat. The other end of the drive rod 4 is provided with a second protrusion 41 that cooperates with the swing rod 3. The second protrusion 41 is located above the swing rod 3.

[0014] The principle of this utility model is as follows: When the cylinder 8 retracts, the cylinder 8 drives the drive rod 4 to rotate upward through the transmission shaft 7. The second protrusion 41 leaves the swing rod 3. At this time, the swing rod 3 is under the counterweight at one end, causing the first protrusion 32 to swing upward at one end. The first protrusion 32 acts on the C-shaped connecting rod 6, which drives the baffle 2 to flip around the hinge seat. The material box 1's lower outlet is opened for material feeding. When the cylinder 8 extends, the cylinder 8 drives the drive rod 4 to rotate downward through the transmission shaft 7. The second protrusion 41 acts on the swing rod 3, and the force is greater than the counterweight of the swing rod 3. At this time, the swing rod 3 swings downward, and the first protrusion 32 leaves the C-shaped connecting rod 6. Since the counterweight of the C-shaped connecting rod 6 and the connecting part 22 is greater than that of the blocking part 21, the baffle 2 cannot flip. The blocking part 21 closes the material box 1's lower outlet.
