[0001] The present application relates to the field of equipment mechanical technology, and in particular to a vacuum bag folding device. Background Art

[0002] There are vacuum bags of various sizes for storing clothes and quilts on the market. When producing and packaging these vacuum bags, the length, width and size are different, and the size specifications after folding are also different. If the folding force of the existing folding equipment is too small, the folded vacuum bag will be loose, easy to scatter and difficult to pack; if the folding force of the folding equipment is too large, the crease will easily damage the sealing chain of the vacuum bag, affecting the use of the product. Utility Model Content

The vacuum bags are loose and easy to be scattered after folding; 3. The sealing chain of the vacuum bags is easily damaged when the folding force is too large. To this end, the application provides a folding device that is easy to fold the vacuum bags neatly without damaging the vacuum bags.

[0004] In order to solve the above technical problems, the utility model provides a vacuum bag folding device, including a feeding platform and a plurality of groups of clamps for folding vacuum bags. The feeding platform feeds from the side of the device, a first material blocking mechanism for adjusting the feeding position is provided under the feeding platform, a transverse movable frame for adjusting the position of the device is provided under the device, and plug plates are provided at the entrance of the clamps parallel to the clamps. The plug plates are connected to the driving mechanism and can perform telescopic movement to insert the front end material into the clamps.

[0005] Furthermore, each channel is composed of two groups of conveyor belts arranged opposite to each other, and two rollers are respectively arranged at the entrance and exit of the channel. The conveyor belts are arranged in parallel and wound around the rollers, and a gap is left when the conveyor belts are arranged to avoid the air valve of the vacuum bag.

[0006] Furthermore, the channel is a first channel, a second channel, a third channel, a fourth channel and a fifth channel which are connected in sequence, and a longitudinal folding platform is provided between the third channel and the fourth channel.

[0007] Furthermore, two rollers at the end of the first clamping channel / the second clamping channel / the third clamping channel are in contact with each other to fold the front end material into a crease.

[0009] Furthermore, the two rollers at the end of the first clamping channel / the second clamping channel / the third clamping channel tend to move closer together, so that the gap between the two rollers can adapt to the thickness of the product.

[0010] Further, the first channel is inclined upward, the second channel is inclined backward, and the third channel is inclined downward and connected to the longitudinal folding platform at the rear end.

[0011] Further, the longitudinal folding platform includes a material receiving platform connected to the third channel and a second material blocking mechanism.

[0026] Embodiment

[0027] As Figure 1 and Figure 9 shown, a vacuum bag folding device includes a feeding platform 1 and multiple chutes 2 for folding. The feeding platform 1 feeds from the side of the device. As Figure 2 shown, a first material blocking mechanism 31 for adjusting the feeding placement position is provided below the feeding platform 1, and a transverse moving frame 41 for adjusting the position of the device is provided below the device. As Figure 3 and Figure 9 shown, insertion plates 5 are provided parallel to the chutes 2 at the entrances of the chutes 2. The insertion plates 5 are connected to the driving mechanism 6 and can perform telescopic movements to insert the front-end materials into the chutes 2. The folding device of the present application is installed at the end of the front-end bag-making machine production line, and the finished vacuum bags of the production line enter from the side of the folding device for folding. When the front-end bag-making machine produces, the sealing chain of the vacuum bag is ultrasonically pressed with the upper and lower plastic films, so the sealing chain end of the finished vacuum bag is on the side of the discharge port and parallel to the direction of the bag-making machine production line. After the finished vacuum bag enters the folding device from the side, the first few folding steps will not involve the sealing chain. The present application places the folding step of the sealing chain at the end, which can effectively avoid damage to the sealing chain when the folded materials are thickened. By adjusting the first material blocking mechanism 31 and the transverse moving frame 41, the placement positions of vacuum bags of different sizes on the feeding platform can be adjusted, which can avoid the position of the air valve and ensure that products of different specifications have the same width after folding.

[0028] As Figure 5As shown, the chute 2 is composed of two sets of conveyer belts 7 arranged oppositely. At the entrance and exit of the chute 2, there are two rollers 8 respectively. The conveyer belts 7 are arranged in parallel and wound around the rollers 8. When the conveyer belts 7 are arranged, an interval is left to avoid the vacuum bag air valve. An interval without a conveyer belt is reserved on the roller 8. By adjusting the first baffle mechanism 31, the vacuum bag air valve is adjusted to the avoidance interval, so that the folding step will not damage the air valve.

[0029] As Figure 3 and Figure 7 As shown, the chute 2 is successively the first chute 21, the second chute 22, the third chute 23, the fourth chute 24 and the fifth chute 25. A longitudinal folding platform 9 is provided between the third chute 23 and the fourth chute 24. The first chute 21 is arranged upward, the second chute 22 is arranged obliquely backward, the third chute 23 is arranged obliquely downward and is connected to the rear longitudinal folding platform 9, the fourth chute 24 is arranged upward, the fifth chute 25 is arranged horizontally, and a structure for receiving the vacuum bag is arranged at the exit of the fifth chute 25.

[0030] As Figure 5 As shown, at the entrance of the first chute, there are a roller a and a roller 1. At the exit of the first chute, there are a roller b and a roller 2. The roller b and the roller 2 are in contact. At the entrance of the second chute, there are a roller c and a roller 2. At the exit of the second chute, there are a roller d and a roller 3. The roller d and the roller 3 are in contact. At the entrance of the third chute, there are a roller e and a roller 3. At the exit of the third chute, there are a roller f and a roller 4. A conveyer belt is wound around the outside of the rollers 1, 2, 3 and 4. Conveyer belts are wound between the roller a and the roller b, between the roller c and the roller d, and between the roller e and the roller f respectively.

[0031] As Figure 5 As shown, the two rollers 8 at the end of the first chute 21 / the second chute 22 / the third chute 23 are in contact to fold a crease on the front-end material. The two rollers 8 in contact with each other at the end of the chute 2 press a crease on the folding part, so that the shape of the folded vacuum bag is relatively fixed and not easy to loosen.

[0032] The first chute 21 / the second chute 22 / the third chute 23 has a large entrance and a small exit. The large entrance is convenient for receiving the folded vacuum bag introduced by the front-end plug board 5. Then the chute 2 becomes narrower to clamp the folded vacuum bag when the plug board 5 exits. The small exit extrudes a crease on the folding edge to make the vacuum bag not easy to disperse.

[0033] There is a tendency for the two rollers 8 at the ends of the first chute 21 / the second chute 22 / the third chute 23 to move closer to each other, so that the gap between the two rollers 8 adapts to the thickness of the product. The tendency to move closer can be achieved through the following structure: When one of the two rollers 8 is installed, a bearing with an adjustable diamond seat is used. One end of the installation hole is fixed, and a spring is fixed on one side of the slot-shaped installation hole at the other end. Under the action of the spring force, this roller leans towards the other roller on the other side. When encountering a folded thick vacuum bag or a sealed chain, the spring is compressed by the force, and the gap between the two rollers slightly increases to adapt to the thickness of the product passing through them.

[0034] As Figure 6 shown, the lower end of the longitudinal folding platform 9 is successively a material receiving platform and a second material blocking mechanism 32. The longitudinal folding platform 9 is provided with a longitudinal moving frame 42, and the longitudinal moving frame 42 can be horizontally adjusted perpendicular to the incoming material direction. By adjusting the second material blocking mechanism 32, the alignment avoidance interval of the vacuum bag air valve can be adjusted, and by adjusting the longitudinal moving frame 42, it can be ensured that products of different specifications have the same length after folding.

[0035] All the above driving mechanisms are driven by servo motors, and the folding position can be controlled more precisely by cooperating with sensors.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Equivalent changes made to the structure, shape, and principle within the knowledge scope of those of ordinary skill in the art all fall within the protection scope of the present invention.
