The working principle of the basic scheme is as follows:
the conveying part is used for conveying the packaging bag to the supporting platform, the packaging part is used for filling the packaging bag, and the sealing part is used for thermally sealing the opening of the packaging bag for packaging food.
The working principle of the packaging part is as follows: when the device is in an initial state, the wedge surfaces of the first wedge block and the second wedge block are attached, and the upper surface of the first wedge block is parallel to the horizontal plane. The wrapping bag is placed on a supporting table, and when food weight in the wrapping bag increases gradually, the supporting table gliding is pushed down, and first piston rod drives first piston along with the supporting table gliding, and the space of first piston barrel lower part reduces, and atmospheric pressure increases, and is gaseous through the pipeline discharge in the second piston barrel.
The working principle of the sealing part is as follows: gas is introduced into the second piston barrel, the air pressure in the second piston barrel is increased, the second piston is pushed to move towards the direction close to the supporting table, the second piston rod drives the hot pressing blocks to move along with the second piston, the two hot pressing blocks move in opposite directions, and the opening of the packaging bag positioned in the middle is heat-sealed when the two hot pressing blocks are attached to each other.
When the device is in an initial state, the wedge surfaces of the first wedge block and the second wedge block are attached, and the upper surface of the first wedge block is flush with the horizontal plane. When the first electromagnet moves along with the second piston rod towards the direction close to the support table, the first electromagnet repels the eccentric block to move towards the direction far away from the first electromagnet, the eccentric block slides in the annular groove, the eccentric block drives the first wedge block to rotate on the second wedge block, and the upper surface of the first wedge block inclines gradually. When the wedge surfaces at the high ends of the first wedge block and the second wedge block are attached to each other and the wedge surfaces at the low ends of the first wedge block and the second wedge block are also completely attached to each other, the inclination degree of the upper surface of the first wedge block is the largest, and the packaging bag slides from the upper surface of the first wedge block.
After the wrapping bag slided, gravity on the brace table disappeared, and first piston relies on the reset action of first spring to drive first piston rod and brace table upward movement and resets, and first piston bucket lower part space increases, extracts the gas in the second piston bucket to first piston bucket in, the gas escape in the second piston bucket, and the second piston drives second piston rod and the first electro-magnet of hot pressing piece and resets. After the first electromagnet resets, the first wedge block rotates to reset by means of the reset action of the torsion spring.
The working principle of the conveying part is as follows: according to the lever principle, the first piston rod drives one end of the connecting rod to move downwards, the other end of the connecting rod drives the rack to move upwards, the rack moves upwards to drive the driving gear to rotate positively, and the driven gear cannot rotate under the influence of the one-way bearing. When the first piston rod drives the supporting table to move upwards and reset, one end of the connecting rod is driven to move upwards, the other end of the connecting rod drives the rack to move downwards, the rack moves downwards to drive the driving gear to rotate reversely, the driving gear drives the driven gear meshed with the driving gear to rotate positively, the driven gear drives the driving roller to rotate, and the driving roller and the driven roller transmit new packaging bags to the supporting table through belt transmission.
The beneficial effect of this basic scheme lies in:
1. food gravity in the wrapping bag makes the brace table gliding, and the gas of first piston bucket lower part passes through the pipeline and discharges simultaneously to two second piston buckets in, and atmospheric pressure in the second piston bucket increases for two second piston rods move in opposite directions, and the hot briquetting is along with being close to each other of second piston rod, accomplishes the heat-seal automatically to the opening of wrapping bag.
2. When the food in the packaging bag reaches a certain weight, the two second piston rods can drive the hot-pressing blocks to mutually approach and stick together. Since each heat-sealing requires the food in the package to reach the set weight, quantitative packaging can be achieved.
3. When the hot pressing piece is moved to the direction close to the packaging bag to complete the heat sealing, the first electromagnet is also moved to the direction close to the supporting table along with the second piston rod, the repulsion action of the first electromagnet on the eccentric block is utilized, the first wedge block is rotated, the upper surface of the first wedge block is inclined, and the packaging bag slides from the upper surface of the first wedge block. Namely, the automatic discharging of the packaging bag can be realized while the heat sealing is finished.
4. After the wrapping bag slided from the brace table, the brace table upward movement resets, and according to lever principle, brace table upward movement makes the rack glide, and the rack drives the driving gear and rotates to realize that the drive roll rotates, drive roll and driven voller pass through belt transmission, convey new wrapping bag to brace table department, realize continuous packing in batches.
Furthermore, a retaining sheet is arranged on the edge of the side wall at the position where the thickness of the first wedge block is maximum. In the rotation process of the first wedge block, the retaining sheet plays a certain role in blocking the packaging bag, the packaging bag is prevented from sliding off the first wedge block after the heat sealing is not finished, and the packaging bag can slide off the upper surface of the first wedge block only when the upper surface of the first wedge block inclines to the maximum degree.
Furthermore, a magnetic baffle is connected to the position of the discharge port in a sliding mode, a second electromagnet used for attracting the baffle is arranged on the rack, and a second spring is fixedly connected between the baffle and the bottom of the storage bin. When the second electromagnet is started, the suction baffle slides to open the discharge hole, food in the storage bin falls into the packaging bag, and when the second electromagnet is closed, the baffle is reset under the action of the spring to block the discharge hole.
Furthermore, a limit switch is fixedly connected to the rack above the supporting plate and used for starting the second electromagnet. Backup pad upward movement and limit switch offset and trigger limit switch, start the second electro-magnet, and the discharge gate is opened, and new wrapping bag conveys to a supporting bench at this moment, and food can be followed the storage silo and inwards dropped to the wrapping bag.
Further, the lower part of the storage bin is in an inverted cone shape. The food in the storage bin is convenient to discharge.
