A packaging bag sealing and conveying device is shown in figure 1 and comprises a conveying device and the packaging bag sealing device;

the conveying end part of the conveying device is opposite to the plastic sealing position of the sealing mechanism.

The conveying device comprises a conveying belt 215, a rear side baffle 218, a second pressing plate 2181, two guide rails 217, two sliding blocks and two second air cylinders 216, and the conveying belt 215 can be replaced by a chain or a synchronous belt to convey the packaging bags;

The conveyor further comprises two conveyor belt flanges 221, the two conveyor belt flanges 221 being symmetrically arranged above the conveyor belt.

As shown in fig. 5, the extension and retraction of the second cylinder 216 causes the rear side dam 218 to move up and down. The conveyor belt 215 is provided with a first position sensor 19 and a second position sensor 20 on one side. The rear end of the conveyor belt 215 is provided with a conveyor belt rib 221.

As shown in fig. 6, the rear side barrier 218 is designed in such a structure that when the second cylinder 16 is contracted to move the rear side barrier 218 downward, the rear side barrier 218 can either block a product-containing bag pushed from one side or press the bag by the upper second pressing plate 2181 when the rear side barrier 216 moves to the lowermost end.

Working mode of the example

As shown in fig. 7, the driving wheel 21 rotates clockwise by an angle a, so that the supporting rod 3 is driven to move to the topmost end of the stroke, and the rod sleeve 6 moves to the bottommost end of the stroke, so that the distance between the heating plate 24 and the backing plate structure 27 is maximized. With the rotation of the driving wheel 21 to a certain angle, the guiding grooves 2101 on both sides, the first guiding rod 211 and the second guiding rod drive the two pulling hooks and the lateral positioning plate 213 to move inwards and keep a certain distance. The first cylinder 214 is now retracted, which rotates the retractor rod 212 to the position shown in the figure.

As shown in fig. 8, before the bag is sealed, the second cylinder 216 is contracted, and the rear flap 218 is lowered to the lowest position along the guide rail 217.

As shown in fig. 9, when the pusher 904 pushes the unsealed packaging bag B filled with the product onto the conveyor belt 215 of the conveyor, the rear side fence 218 of the conveyor is already dropped to position the rear side of the product-filled packaging bag, and the pushed-in product-filled packaging bag can be pressed. The distance between the side positioning plates 213 is slightly larger than the width of the product packaging bag (the distance is adjustable), and two sides of the package filled with the product are positioned. The upper end of the rear side barrier 218 has pressed the bag filled with the product, so the pusher 904 can be withdrawn to avoid bringing back the bag when withdrawing.

As shown in fig. 10, when the bag filled with the product is positioned, the first cylinder 214 extends forward, the draw hook is driven by the cylinder to rotate to the position shown in the figure, and the claw of the draw hook just enters the space at the front end of the bag, which is not occupied by the product.

As shown in fig. 11, after the hook claw of the drag hook enters the front end of the packaging bag, the driving wheel 21 rotates counterclockwise by the same angle a, and the two drag hooks and the two lateral positioning plates 213 are driven to move to both sides by the two positioning transmission mechanisms, at the same time, the sealing transmission mechanism drives the heating plate 24 and the first pressing plate 25 to move downward, and the rod sleeve 26 drives the backing plate structure 27 to move upward. The first press plate 25 then compacts the bag filled with product, and the heating plate 24 and the backing plate structure 27 just touch each other when the two hooks are moved to the maximum stroke distance, thereby sealing the mouth of the bag.

The bag now does not require rear positioning so the rear flap 218 is raised. Then, the driving wheel 21 rotates clockwise by an angle a, the two pulling hooks and the two lateral positioning plates 213 move inwards, and when the pulling hooks move to the minimum stroke, the first air cylinder 214 retracts, and the pulling hooks rotate. At the same time, the heating plate 24 and the backing plate structure 27 move up and down to the maximum stroke distance. The components of the sealing portion return to the positional relationship before the sealing as shown in fig. 7.

As shown in fig. 12, when the packaging bag of the product is sealed, the packaging bag needs to be conveyed away by a conveyor belt, the position of the current packaging bag is vacated, and the next unsealed packaging bag is conveyed to continue sealing.

As shown in fig. 13, the conveyor 215 of the conveyor starts to convey the sealed package to the right, and if the first position sensor 19 and the second position sensor 20 can detect the signal at this time, it means that the package has not completely entered the conveyor rib 221, the rear flap 218 cannot fall, and the next unsealed package cannot be fed into the seal. When the first position sensor 19 and the second position sensor 20 do not detect the signal, it indicates that the sealed package enters the conveyor belt rib 221, and then the package can be smoothly conveyed under the constraint of the rib. If either of the first position sensor 19 and the second position sensor 20 can detect a signal for a period of time, indicating that the bag is in a problem during the transport process, the system alarms.

When the second position sensor 20 does not detect the signal, the belt 215 stops conveying, the rear side stop 218 falls, and the next unsealed packaging bag can be continuously conveyed into the sealing conveying equipment for positioning and sealing.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
