Betel nut packing machine

[0029] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the following embodiments, that is, all simple equivalent changes and modifications made based on the scope of the patent application of the present invention and the content of the description still fall within the scope of the patent of the present invention.

[0030] See attached Figure 1-4 , A betel nut packaging machine, including a frame, the frame is provided with a feeding unit, a counting unit, a filling unit, and a sealing unit in sequence. The feeding unit includes a vibrating plate 11 and a vibrating flow channel 12, the vibrating plate A spiral flow channel is arranged inside, and a plurality of small holes are arranged on the outermost flow channel, and the outlet end of the outermost flow channel extends to the outside of the vibrating plate and is staggered and arranged above the inlet end of the flat vibration flow channel, The outlet end of the flat vibrating flow channel is staggered and arranged above a silo 31; the counting unit includes an optical fiber 32 arranged on one side of the silo 31 for counting the number of betel nuts falling into the silo; The loading unit includes a flap 41 arranged at the bottom of the silo, a flap drive mechanism 42, and a feeding hopper 43 arranged below the flap. The outlet end of the feeding hopper is symmetrically provided with a bag clamping mechanism 44 on both sides The bottom of the bag clamping mechanism is arranged on the upper and lower transmission mechanism 45; the sealing unit includes a pair of pre-sealing bag mechanisms 51 and a pair of heat-sealing mechanisms 52, the pre-sealing bag mechanism includes two sides for clamping the betel nut packaging bag The two clamping jaws 511, and two horizontal cylinders 512 that drive the two clamping jaws to move to the left and right sides of the horizontal plane to flatten the betel nut packaging bag. The heat sealing mechanism includes a pair of heating rods 521 and a pair of heating rods 521 for testing. The thermocouple 522 for the temperature of the heating rod, and the front and rear cylinders 523 for driving a pair of the heating rods to move back and forth to heat-seal the betel nut packaging bag; a finished product collection box is provided under the sealing unit 61.

[0031] Wherein, the base of the horizontal cylinder is fixed on one end of a support block 513, the other end of the support block is provided with a U-shaped groove 514, and a fastening bolt is also provided, and the other end of the support block is tightened by the fastening bolt. Fixed on the U-shaped groove and the frame. Due to the arrangement of the U-shaped groove and the fastening bolts, the distance of the supporting block on the frame can be adjusted, so that the initial distance between the two clamping jaws 511 can be adjusted to adapt to the betel nut packaging bags of different radius sizes.

[0032] The flap drive mechanism includes a stepping motor 421, a motor fixing base 422, and a coupling 423. The stepping motor is fixed on the motor fixing base, and the power output shaft of the stepping motor is connected to the drive through the coupling. The flap is used to drive the flap to rotate to open and close the bottom of the silo.

[0033] The vibrating plate, the flat vibrating flow channel, the silo, the turning plate and the turning plate driving mechanism are all two, and they are arranged symmetrically. The optical fiber is a through-beam optical fiber sensor. The bag clamping mechanism is a clamping jaw cylinder. The upper and lower transmission mechanism includes a motor and a conveyor belt.

[0034] The betel nut packaging machine uses a vibrating plate for feeding. There are multiple small holes in the vibrating plate. Betel nut scum and betel nut stems can fall from these small holes, but betel nut cannot fall from these small holes, thus vibrating The tray realizes the function of removing stems and scum. The betel nuts come out of the circular vibrating plate one by one, and are transported to the counting mechanism through the flat vibration channel one by one, and finally fall into the silo of the flap mechanism. There are two silos in the flap mechanism, and 7 pieces are counted. Then (the corresponding quantity can be set according to the quantity of each pack of betel nuts). The vibration plate and the flat vibrating flow channel will stop feeding. At this time, the 8th betel nut is still on the flat vibrating flow channel, and there are 7 betel nuts on both sides, which is exactly one. Pack the quantity of betel nut.

[0035] Manually put a bag of desiccant into the bag, and then put the bag into the discharge hopper. The person stepped on the foot switch to give a signal, and the bag clamping mechanism 44 clamps the bag (adjusting the distance between the two clamping jaws can be applied to different Packaging bag), the upper flap is turned over under the drive of the flap drive mechanism, so that the full 14 betel nuts fall into the packaging bag through the cutting hopper. At this time, the upper feeding unit starts to count the next For betel nut packaging, the entire group of sealing mechanisms below move to the bottom of the filled betel nut bag after sensing that the hand has left the working area of ​​the mechanism. The clamping jaws on the pre-sealing bag mechanism clamp the packaging bag, and the upper bag clamping mechanism is released Pack the bag, and then the whole group of sealing mechanism clamps the bag to move to the heat-sealing position. The clamping jaws on both sides of the pre-sealing bag mechanism simultaneously pull the bag to make the opening of the bag flat when filling. Finally, the heat sealing mechanism comes out to seal the flat position of the packaging bag. After sealing, the bag clamping mechanism is released, and the packaging bag falls into the finished product flow line, and then falls into the finished product collection box via the conveyor belt.

[0036] The betel nut packaging machine is an automated packaging equipment designed and developed for betel nut packaging in the food industry. It is also suitable for bag-type packaging of various pellets. The simple operation of the machine and high productivity make it very suitable for large-scale and high-volume packaging. Production operation requirements.

[0037] The betel nut packaging machine requires one person to cover the bag, and one person can pack 12 to 15 packs in one minute after a skilled operation, which is equivalent to the manual packaging output of 2 to 2.5 people per minute. This betel nut packaging machine adopts vibrating plate and flat vibrating feeding, which effectively solves the rare problem of betel nut counting. The betel nut packaging machine has a small area and low noise during operation, which is suitable for various food enterprises and individual users. In addition, the investment cost of the betel nut packaging machine is relatively small, and the investment cost is recovered quickly. If the equipment market price is reasonable, it should have a very good application prospect.
