Description

Technical Field

[0001] The present invention relates to the technical field of food packaging, and particularly to an automatic packaging machine for small pieces of food. Background Art

[0002] With the continuous increase in consumers' demand for food, the types of food in the market are becoming increasingly rich. In particular, small pieces of food such as dried meat, dried fruits, and nuts are deeply loved by consumers because they are convenient to eat and carry. Traditional manual packaging not only has low efficiency, but also easily has problems such as non-standard packaging, food hygiene problems, and high labor costs.

[0003] The Chinese invention patent with the publication number of CN119218510A in the prior art discloses a packaging device for small snacks of dried meat. It includes a self-sealing bag. This device can be used by being slotted and assembled on a conventional operation tabletop, and has high universality in installation and use. Its packing mechanism is located at the notch of the material trough, and includes guide plates symmetrically arranged on both sides of the material trough. The guide plates are connected by a cylinder. A first transfer plate is provided at the top of the packing mechanism, and this transfer plate is connected with a first suction cup. This device can realize the opening, sealing and blanking control of the self-sealing bag, and the operation is simple. Only by feeding the material can the small packaging of the dried meat be completed. Although this device can efficiently complete the feeding and packaging work, during the specific implementation of the device, the continuity of the device cannot be guaranteed. Only one packaging can be carried out for one feeding, which greatly reduces the packaging efficiency.

An air inlet pipe 405 is fixedly installed at the air inlet chamber of the adsorption seat 401, an air exhaust pipe 404 is fixedly installed at the air exhaust chamber of the adsorption seat 401, an adsorption pipe 406 is installed at the adsorption chamber of the adsorption seat 401, a pneumatic transfer block 407 for guiding the air flow is installed at the air flow chamber of the adsorption seat 401, a sliding closing rod 402 is slidably installed at the blocking chamber of the adsorption seat 401, a return spring III 403 is fixedly installed on the sliding closing rod 402. The first end of the return spring III 403 is fixedly installed with the sliding closing rod 402, and the second end of the return spring III 403 is fixedly installed with the blocking chamber of the adsorption seat 401. Both the air exhaust pipe 404 and the air inlet pipe 405 are connected to an air flow system (the system adopts an existing technical solution) for introducing high-pressure air flow into the adsorption seat 401 and discharging the air flow.

[0020] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the support assembly 1 includes a support frame I 101, a support frame II 102, a support frame III 103, and a packaging bag 104. The support frame I 101 is provided with four for installing and fixing a packaging table 201 and a mounting disc 240. The support frame II 102 is used for installing a mounting rotating shaft I 241 and a motor 232.

[0027] During operation, the motor 232 is started to drive the push rotating shaft 234 to rotate, and then drive the intermittent push rod 247 to rotate around the output shaft of the motor 232. After the intermittent push rod 247 rotates into the intermittent groove of the intermittent turntable 233, it drives the intermittent turntable 233 to rotate. After the intermittent push rod 247 disengages from the intermittent groove of the intermittent turntable 233, the intermittent turntable 233 stops rotating, thereby enabling the clamping assembly to rotate intermittently. After the intermittent push rod 247 disengages from the intermittent groove of the intermittent turntable 233, the rotating intermittent push rod 247 contacts the push plate 231 and pushes the push plate 231 to move in the direction of the piston cylinder IV 230, thereby assisting the discharge assembly to open; Four working positions are set for the intermittently transferred clamping assembly. When the clamping assembly moves to the first working position, that is, below the bag placing assembly 6, the packaging bag 104 is placed between the two mounting plates 211 through the bag placing assembly 6 (this bag placing assembly adopts an existing technical solution). After the placement is completed, it moves to the next working position, that is, below the placing assembly 4. During the movement, the gears of the two rotating shafts I 213 rotate respectively under the action of the rack I 235 and the rack II 236 (as Figure 15As shown), the two push rods I 212 are pushed axially inward, and the mounting plate 211 is pushed axially inward, so that the adsorption head I 224 adsorbs the packaging bag 104. After the adsorption is completed, the clamping assembly continues to move, and the rotating shaft I 213 is reset under the action of the torsion spring II 216. The push rod I 212 is reset under the action of the reset spring I 219, so that the mounting plate 211 and the adsorption head I 224 open with the packaging bag 104. The clamping assembly continues to move. When it moves to the rack III 237, the gears of the two rotating shafts II 214 rotate respectively under the action of the two gear teeth of the rack III 237 (as shown). Figure 16 As shown), the push rod I 212 is pushed outwardly, and the mounting plate 211 is driven to move outwardly, and the packaging bag 104 is driven to open completely. After the packaging bag 104 is fully opened, the ratchet 246 cooperates with the arc-shaped ratchet bar 238 so that the rotating shaft II 214 cannot be reset (as shown). Figure 9 As shown), the opening of the packaging bag 104 remains open.

[0028] After the packaging bag 104 is opened, the clamping assembly moves to the second station. After moving to the second station, it stops intermittently and puts small pieces of food from the discharge assembly 5 into the packaging bag 104 through the feeding assembly 4. After the feeding is completed, the transfer continues, and the clamping assembly drives the packaging bag 104 to continue moving. During the movement, the ratchet of the rotating shaft II 214 and the arc-shaped ratchet 238 cooperate with the reset torque of the torsion spring I 215 to make the rotating shaft II 214 swing slightly, thereby causing the mounting plate 211 to drive the two sides of the packaging bag 104 to swing slightly, thereby ensuring that the small pieces of food in the packaging bag 104 fall to the bottom of the packaging bag 104. After ensuring that the small pieces of food fall to the bottom of the packaging bag 104, the ratchet of the rotating shaft II 214 removes the range of the arc-shaped ratchet 238, and the rotating shaft II 214 is reset under the action of the torsion spring I 215. The push rod I 212 is reset under the action of the reset spring I 219, thereby causing the mounting plate 211 to drive the bag openings of the packaging bag 104 to move closer to each other.

[0029] After the approach is completed, the clamping assembly moves to the third station, stops intermittently, and seals the two ends of the packaging bag 104 through the packaging assembly 3 to ensure that the interior of the packaging bag 104 is in a closed state, thereby completing the closed packaging work. After the packaging work is completed, the clamping assembly continues to move. During the movement, the pushing block 239 pushes the top rod 222 to move upward, thereby pushing the sliding push plate 221 to move away from the mounting plate 211, thereby causing the closing plug 223 to break away from the contact with the adsorption head I224, thereby causing the air pressure in the adsorption head I224 to return to normal, thereby causing the adsorption head I224 to separate from the packaging bag 104. After the separation is completed, the top rod 222 is reset under the action of the spring, and at the same time, the closing plug 223 is reset under the action of the spring, thereby releasing the adsorption of the packaging bag 104.

[0030] After the adsorption is released, the clamping assembly moves the packaging bag 104 to the fourth station and stops intermittently. At this time, the two electromagnetic blocks 226 are respectively energized to adsorb the magnet blocks 225 on the sliding discharge door I 217 and the sliding discharge door II 218. At this time, the intermittent push rod 247 pushes the push plate 231 in the direction of the piston cylinder IV 230, so that the gas in the piston cylinder IV 230 is compressed into the piston cylinder III 229, so that the two pulling plates 228 move axially outwards, driving the two electromagnetic blocks 226 to move, and then driving the sliding discharge door I 217 and the sliding discharge door II 218 to move axially outwards. After the sliding discharge door I 217 and the sliding discharge door II 218 are fully opened, the packaging bag 104 falls from the openings of the sliding discharge door I 217 and the sliding discharge door II 218 into the discharge pipe 203 and is finally discharged through the discharge pipe 203. After the discharging work is completed, the intermittent push rod of the driving rotating shaft 234 no longer pushes the push plate 231, and the push plate 231 resets under the action of the spring. The return spring II 227 also resets under the action of the spring, driving the sliding discharge door I 217 and the sliding discharge door II 218 to reset. After the reset, the electromagnetic block 226 is powered off and no longer adsorbs the magnet block 225, so that the sliding discharge door I 217 and the sliding discharge door II 218 are no longer fixed, and the entire packaging discharging work is completed.

[0031] At the same time, when the encapsulation assembly 3 and the feeding assembly 4 need to be started, the air cylinder 204 is started, and the gas in the piston cylinder I 205 is compressed and flows into the piston cylinder V 302 and the piston cylinder II 206, so that the gas in the piston cylinder V 302 increases, so that the piston push rod II 303 drives the encapsulator 304 to move downwards to encapsulate the packaging bag 104. The gas in the piston cylinder II 206 increases, so that the piston push rod I 207 moves axially outwards. At this time, the adsorption seat 401 just moves above the second station, and the piston push rod I 207 pushes the sliding closing rod 402 to close the air flow cavity of the adsorption seat 401, so that the adsorption tube 406 no longer adsorbs the small pieces of food, so that the food falls into the packaging bag 104, and the feeding and encapsulation of the small pieces of food are completed.

[0032] Embodiment 3: As Figure 4 and Figure 5As shown in the figure, the encapsulation component 3 includes a mounting base 301 fixedly installed on the baffle 202. A piston cylinder V 302 is fixedly installed on the mounting base 301. A piston push rod II 303 is slidably installed on the piston cylinder V 302. A spring is fixedly installed on the piston push rod II 303. One end of the spring is fixedly installed with the piston push rod II 303, and the other end is fixedly installed with the mounting base 301. The inner cavity of the piston cylinder V 302 is communicated with the piston cylinder I 205 through the first connecting pipe of the piston cylinder I 205. An encapsulator 304 for encapsulating the packaging bag 104 is also fixedly installed on the piston push rod II 303. During operation, when the clamping component moves the packaging bag 104 to the lower part of the encapsulation component 3, the piston push rod II 303 moves downward under the action of the air cylinder 204, so that the encapsulator 304 approaches the packaging bag 104 downward, and then the encapsulation of the packaging bag 104 is completed through the encapsulator 304.

[0033] The feeding component 4 includes a transfer seat 408 fixedly installed on the support frame III 103. The transfer seat 408 includes a mounting arm and a driving seat. The mounting arm of the transfer seat 408 is used for fixedly installing the adsorption seat 401. The driving seat of the transfer seat 408 is used for driving the adsorption seat 401 to rotate. An air inlet cavity, an air exhaust cavity, an adsorption cavity, an air flow cavity and a blocking cavity are arranged on the adsorption seat 401. An air inlet pipe 405 is fixedly installed at the air inlet cavity of the adsorption seat 401. An air exhaust pipe 404 is fixedly installed at the air exhaust cavity of the adsorption seat 401. An adsorption pipe 406 is installed at the adsorption cavity of the adsorption seat 401. A flat adsorption head for preventing food damage (the flat adsorption head adopts an existing technical solution) is fixedly installed on the adsorption pipe 406. A pneumatic shift block 407 for guiding air flow is installed at the air flow cavity of the adsorption seat 401. A sliding closing rod 402 is slidably installed at the blocking cavity of the adsorption seat 401. A return spring III 403 is fixedly installed on the sliding closing rod 402. One end of the return spring III 403 is fixedly installed with the sliding closing rod 402, and the other end is fixedly installed with the blocking cavity of the adsorption seat 401. Both the air exhaust pipe 404 and the air inlet pipe 405 are communicated with the air flow system for providing air flow to the adsorption seat 401.

[0034] During operation, the adsorption seat 401 is moved to the upper part of the discharging component 5 by starting the transfer seat 408. High-pressure gas is filled into the adsorption seat 401 through the air inlet pipe 405. The air flow is guided by the pneumatic shift block 407, enters from the air inlet pipe 405 and flows out from the air exhaust pipe 404, so that the adsorption pipe 406 is in a negative pressure state. Then, the small snacks are adsorbed through the flat adsorption head on the adsorption pipe 406. After the adsorption is completed, the adsorption seat 401 is driven by the transfer seat 408 to move to the upper part of the second working station. The sliding closing rod 402 is pushed by the piston push rod I 207 to move, so that the air exhaust cavity is closed, and the gas at the adsorption pipe 406 flows back to blow off the small snacks, so that the small snacks fall into the packaging bag 104 to complete the feeding work.
