Description

Technical Field

[0001] The utility model relates to the field of manufacturing buffer air cushions, in particular to an anti-sticking structure for the discharge of an air cushion machine and an air cushion machine. Background Art

[0002] In logistics transportation, it is necessary to protect some fragile and easily scratched items to reduce the probability of damage. Currently, it is generally done by placing paper pads or air cushions in a logistics box or a courier box for filling and laying around the items to play a role in shock absorption, impact resistance and other protection.

[0003] An air cushion machine is a device for producing buffer air cushions. By filling gas into a film material and performing heat sealing through a heating structure, a three-dimensional series of connected buffer air cushions are produced.

[0004] The heat sealing structure in an air cushion machine generally uses a heating wheel with heating wires to heat the opening of the film material to seal the opening. During the process of the heating wheel heating and heat-sealing the film material, since the melted part of the film material has a certain viscosity, the film material will be wound by the heating wheel, thereby increasing the heating time of the film material, resulting in overheating, damage to the film material, and there will also be a situation of film material jamming and accumulation. As a result, the subsequent film material will also be overheated and damaged, and at the same time, the film material cannot be discharged normally. On the one hand, it causes waste of the film material, on the other hand, it reduces the production efficiency of the film material, and at the same time, the stacking and extrusion of the film material may also increase the probability of equipment failure.

[0005] Therefore, how to avoid the film material after heat sealing from being wound is a technical problem that those skilled in the art need to solve urgently. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an anti-sticking structure for the discharge of an air cushion machine and an air cushion machine to solve at least one of the above technical problems.

[0007] According to one aspect of the utility model, an anti-sticking structure for the discharge of an air cushion machine is provided, including:

[0008] A rotatable heating wheel for heat-sealing a film material;

[0009] A rotatable wheel body for jointly pressing and heat-sealing the film material with the heating wheel; and

[0010] A guiding part for restricting the discharge direction of the film material, the guiding part is arranged on the side of the heating wheel and / or the wheel body, and the guiding part is located in the downstream direction of the heating wheel and the wheel body.

[0011] The anti - sticking structure for the discharge of the air cushion machine of the present utility model is installed on the air cushion machine. After the air cushion machine fills the air chamber in the film material with gas, the heating wheel and the wheel body jointly press on the inflation port of the film material for press - fitting heat - sealing and at the same time traction the film material to be conveyed downstream. When the heating wheel and the wheel body perform press - fitting heat - sealing on the film material, the guiding part can limit the discharge direction of the film material, guide the film material after inflation heat - sealing to discharge forward (the downstream direction of the film material conveyance), reduce the possibility that the film material is wound and bent by the heating wheel and / or the wheel body, so as to resist the film material being wound by the heating wheel and / or the wheel body.

[0012] In some embodiments, it may further include an upper shield. The upper shield covers the heating wheel, and the upper shield is provided with an extension part to form a guiding part. Thus, the guiding part formed by the extension part on the upper shield can limit the discharge direction of the film material, guide the film material after inflation heat - sealing to discharge forward, reduce the possibility that the film material is wound and bent by the heating wheel, can resist the tendency of the film material to be wound upward, and the upper shield can also protect the heating wheel and avoid the operator from being injured by contacting the heating wheel.

[0013] In some embodiments, the extension part may extend from the side of the upper shield close to the wheel body in the downstream direction of the film material conveyance. Thus, in this way, the guiding part formed by the extension part can guide the film material after inflation heat - sealing to discharge forward, reducing the possibility that the film material is wound and bent by the heating wheel.

[0014] In some embodiments, the side of the upper shield close to the wheel body may be inclined. Thus, in this way, the guiding part formed by the extension part can further guide the film material after inflation heat - sealing to discharge forward, greatly reducing the possibility that the film material is wound and bent by the heating wheel.

[0015] In some embodiments, it may further include a lower guard plate. The lower guard plate is arranged on the mounting shaft for mounting the wheel body. The wheel body is rotatably connected to the mounting shaft, and the lower guard plate is provided with a limiting part to form a guiding part. Thus, the guiding part formed by the limiting part on the lower guard plate can limit the discharge direction of the film material, guide the film material after inflation heat - sealing to discharge forward, reduce the possibility that the film material is wound and bent by the wheel body, can resist the tendency of the film material to be wound downward, and the lower guard plate can also protect the wheel body.

[0016] In some embodiments, the guiding part is an upper guiding strip. At least one first annular groove is provided on the heating wheel along the circumferential direction, and the upper guiding strip extends into the first annular groove on the heating wheel. The upper guiding strip is located in the downstream direction of the heating wheel. Thus, the upper guiding strip can limit the discharge direction of the film material, guide the film material after inflation heat - sealing to discharge forward, guide the film material away from the heating wheel, and avoid the film material from adhering to the heating wheel.

[0017] In some embodiments, the guiding part is a lower guiding strip. At least one second annular groove is provided on the wheel body in the circumferential direction. The lower guiding strip extends into the second annular groove on the wheel body, and the lower guiding strip is located in the downstream direction of the wheel body. Thus, the lower guiding strip can limit the discharging direction of the film material, guide the film material after inflation and heat sealing to discharge forward, guide the film material to leave the wheel body, and prevent the film material from adhering to the wheel body.

[0018] In some embodiments, a longitudinal baffle can be provided on the upper shield. The longitudinal baffle is located on the side of the heating wheel and the extending part is formed by extending from the side of the longitudinal baffle close to the wheel body in the downstream direction of the film material conveyance. Thus, in this way, the extending part (guiding part) formed by extending from the side of the longitudinal baffle close to the wheel body in the downstream direction of the film material conveyance can guide the film material after inflation and heat sealing to discharge forward, reduce the possibility that the film material is wound and bent by the heating wheel, and moreover, the longitudinal baffle can protect the heating wheel and also prevent the operator from being injured by contacting the heating wheel.

[0019] In some embodiments, the side of the longitudinal baffle close to the wheel body can be inclined. Thus, in this way, the guiding part formed by the extending part can further guide the film material after inflation and heat sealing to discharge forward, greatly reducing the possibility that the film material is wound and bent by the heating wheel.

[0020] According to another aspect of the present invention, an air cushion machine is further provided, which includes an air cushion machine body and an anti-sticking structure for the air cushion machine discharging. The heating wheel and the wheel body are both arranged on the air cushion machine body.

[0021] For the air cushion machine of the present invention, after the air cushion machine fills the air chamber on the film material with gas, the heating wheel and the wheel body jointly press and seal at the inflation port of the film material for pressing and heat sealing and simultaneously traction the film material to convey and discharge in the downstream direction. When the heating wheel and the wheel body perform pressing and heat sealing on the film material, the guiding part can limit the discharging direction of the film material, guide the film material after inflation and heat sealing to discharge forward (in the downstream direction of the film material conveyance), reduce the possibility that the film material is wound and bent by the heating wheel and / or the wheel body, so as to resist the winding of the film material by the heating wheel and / or the wheel body.

In addition, the anti-sticking structure for the discharge of the air cushion machine may further include an upper shield 4 and a lower guard plate 5.

[0030] Reference Figure 1 , the heating wheel 1 is fixed on a driving shaft 103. The driving shaft 103 rotates under the driving action of the driving component on the air cushion machine, so as to realize the rotation of the heating wheel 1. Heating wires are arranged on the heating wheel 1, and the rotating heating wheel 1 can heat-seal the film material.

[0031] Reference Figure 1 and Figure 2 , the wheel body 2 is installed on an installation shaft 21. The installation shaft 21 is installed on the air cushion machine. The wheel body 2 can be installed on the installation shaft 21 through a bearing component. The wheel body 2 can rotate freely on the installation shaft 21. The wheel body 2 is located below the heating wheel 1. The wheel body 2 and the heating wheel 1 can jointly press and heat-seal the film material. After the air cushion machine fills the air chamber on the film material with gas, the edge of the film material passes through between the heating wheel 1 and the wheel body 2. The heating wheel 1 and the wheel body 2 jointly press and heat-seal at the air inlet of the film material and at the same time pull the film material to be conveyed downstream ( Figure 1 the opposite direction of direction A in

[0032] Reference Figures 1 to 3, the upper shield 4 covers the heating wheel 1. Specifically, the upper shield 4 can be installed on the air cushion machine and cover the heating wheel 1. The upper shield 4 can protect the heating wheel 1 and prevent the operator from being injured by contacting the heating wheel 1.

[0033] Reference Figure 1 , in this embodiment, an extension 41 is formed on the upper shield 4 to form a guiding portion. That is, the extension 41 on the upper shield 4 in this embodiment is a guiding portion. Specifically, it can be: Reference Figure 1 And Figure 2 , a longitudinal baffle 42 is formed on the upper shield 4. The longitudinal baffle 42 is located at the side of the heating wheel 1. A gap is left between the longitudinal baffle 42 and the heating wheel 1 to not affect the normal rotation of the heating wheel 1. The extension 41 extends from the side of the longitudinal baffle 42 close to the wheel body 2 in the downstream direction of the film material conveyance. The extension 41 is the pointed corner position of the longitudinal baffle 42 on the upper shield 4 facing the downstream direction of the film material conveyance. The side of the longitudinal baffle 42 close to the wheel body 2 is inclined, that is, the extension 41 has a tendency to extend obliquely downward in the downstream direction of the film material conveyance. In this way, the extension 41 on the longitudinal baffle 42 can limit the discharging direction of the film material, guide the film material after inflation heat sealing to discharge forward (the downstream direction of the film material conveyance), reduce the possibility of the film material being wound and bent by the heating wheel 1, and the extension 41 on the longitudinal baffle 42 can resist the tendency of the film material to be wound upward.

[0034] Reference Figure 2 , the lower guard plate 5 is fixed on the mounting shaft 21 for mounting the wheel body 2, and the lower guard plate 5 does not rotate with the wheel body 2. In this embodiment, a limiting portion 51 is formed on the lower guard plate 5 to form another guiding portion. That is, the limiting portion 51 on the lower guard plate 5 in this embodiment is another guiding portion. The limiting portion 51 is located below the downstream direction of the extension 41. The limiting portion 51 is the upper corner position of the lower guard plate 5 facing the downstream direction of the film material conveyance. The limiting portion 51 on the lower guard plate 5 can limit the discharging direction of the film material, guide the film material after inflation heat sealing to discharge forward, reduce the possibility of the film material being wound and bent by the wheel body 2, and the limiting portion 51 on the lower guard plate 5 can resist the tendency of the film material to be wound downward. Moreover, the lower guard plate 5 can also protect the wheel body 2.

[0035] In other embodiments, the guiding portion can also be only the extension 41 on the upper shield 4.

[0036] Reference Figure 1 , a gap is left between the bottom of the longitudinal baffle 42 on the upper shield 4 and the top of the lower guard plate 5 for the film material to pass through.

[0037] Reference Figure 1, the air cushion machine includes an air cushion machine body 10 and the above-mentioned anti-sticking structure for the discharge of the air cushion machine. The heating wheel 1 is fixed on the drive shaft 103, and the drive shaft 103 is installed on the air cushion machine body 10. The drive component in the air cushion machine body 10 can drive the drive shaft 103 to rotate, and the drive shaft 103 drives the heating wheel 1 to rotate. The wheel body 2 is installed on the mounting shaft 21 ( Figure 2 as shown), the mounting shaft 21 is installed on the air cushion machine body 10, the wheel body 2 is installed on the mounting shaft 21 through a bearing component, and the wheel body 2 can rotate freely on the mounting shaft 21. The wheel body 2 is located below the heating wheel 1, and the wheel body 2 and the heating wheel 1 can jointly press and heat-seal the film material. The roller 101 on the air cushion machine body 10 is used to carry the original film roll in a roll shape. The film material sent out from the original film roll is inflated through the inflation nozzle 102 on the air cushion machine body 10 and then clamped by the heating wheel 1 and the wheel body 2. The heating wheel 1 and the wheel body 2 jointly press and heat-seal at the inflation port of the film material and at the same time traction the film material to be conveyed downstream for discharging. When the heating wheel 1 and the wheel body 2 press and heat-seal the film material, a guiding portion formed by the extension portion 41 on the upper shroud 4 can limit the discharging direction of the film material, guiding the film material after inflation and heat-sealing to discharge forward (the downstream direction of the film material conveyance), reducing the possibility that the film material is curled and bent by the heating wheel 1, and resisting the upward curling trend of the film material. Another guiding portion formed by the limiting portion 51 on the lower guard plate 5 can also limit the discharging direction of the film material, guiding the film material after inflation and heat-sealing to discharge forward (the downstream direction of the film material conveyance), reducing the possibility that the film material is curled and bent by the wheel body 2, and resisting the downward curling trend of the film material.

[0038] Embodiment 2:

[0039] Figure 3 Schematically shows the structure of the anti-sticking structure for the discharge of the air cushion machine in another embodiment of the present utility model.

[0040] Refer to Figure 3 , an anti-sticking structure for the discharge of an air cushion machine, including a heating wheel 1, a wheel body 2 and a guiding portion. In addition, the anti-sticking structure for the discharge of the air cushion machine may further include an upper guiding strip 6 and a lower guiding strip 7.

[0041] In this embodiment, the installation manners of the heating wheel 1 and the wheel body 2 are the same as those in Embodiment 1, and will not be elaborated here.

[0042] The difference between this embodiment and Embodiment 1 is that in this embodiment, the anti-sticking structure for the discharge of the air cushion machine does not include the upper shroud 4 and the lower guard plate 5, that is, the guiding portion is not the extension portion 41 on the upper shroud 4 and the limiting portion 51 on the lower guard plate 5. The guiding portion is the upper guiding strip 6 and the lower guiding strip 7. Of course, in other embodiments, the upper guiding strip 6 and the lower guiding strip 7 may also be installed on the basis of installing the upper shroud 4 and the lower guard plate 5. That is, in other embodiments, the guiding portion may include the extension portion 41 on the upper shroud 4, the limiting portion 51 on the lower guard plate 5, the upper guiding strip 6 and the lower guiding strip 7.

[0043] Reference Figure 3 In this embodiment, the upper guide strip 6 is a guiding portion. At least one first annular groove 11 is formed on the heating wheel 1 in the circumferential direction. In this embodiment, the number of the first annular grooves 11 is one. The left end of the upper guide strip 6 is fixed on the upper mounting plate 61 (or can be integrally formed). The right end of the upper guide strip 6 extends into the first annular groove 11 on the heating wheel 1. The right end of the upper guide strip 6 does not contact the heating wheel 1 to ensure that it does not affect the normal rotation of the heating wheel 1. The upper mounting plate 61 can be fixed on the air cushion machine. The upper guide strip 6 is located in the downstream direction of the heating wheel 1. The upper guide strip 6 can limit the discharging direction of the film material, guide the film material after inflation and heat sealing to discharge forward, guide the film material away from the heating wheel 1, and prevent the film material from adhering to the heating wheel 1. In other embodiments, the number of the first annular grooves 11 can be adjusted according to its width dimension. If the width of the first annular groove 11 is narrow, multiple first annular grooves 11 can be provided on the heating wheel 1. If the width of the first annular groove 11 is wide, only one first annular groove 11 needs to be provided on the heating wheel 1. The number of the upper guide strips 6 is the same as the number of the first annular grooves 11, and one upper guide strip 6 correspondingly extends into one first annular groove 11.

[0044] Reference Figure 3 In this embodiment, the lower guide strip 7 is another guiding portion. At least one second annular groove 22 is formed on the wheel body 2 in the circumferential direction. In this embodiment, the number of the second annular grooves 22 is one. The left end of the lower guide strip 7 is fixed on the lower mounting plate 71 (or can be integrally formed). The right end of the lower guide strip 7 extends into the second annular groove 22 on the wheel body 2. The right end of the lower guide strip 7 does not contact the wheel body 2 to ensure that it does not affect the normal rotation of the wheel body 2. The lower mounting plate 71 can be fixed on the air cushion machine. The lower guide strip 7 is located in the downstream direction of the wheel body 2. The lower guide strip 7 is located below the upper guide strip 6. The film material after heat sealing passes through the gap between the upper guide strip 6 and the lower guide strip 7. The lower guide strip 7 can limit the discharging direction of the film material, guide the film material after inflation and heat sealing to discharge forward, guide the film material away from the wheel body 2, and prevent the film material from adhering to the wheel body 2. In other embodiments, the number of the second annular grooves 22 can be adjusted according to its width dimension. If the width of the second annular groove 22 is narrow, multiple second annular grooves 22 can be provided on the wheel body 2. If the width of the second annular groove 22 is wide, only one second annular groove 22 needs to be provided on the wheel body 2. The number of the lower guide strips 7 is the same as the number of the second annular grooves 22, and one lower guide strip 7 correspondingly extends into one second annular groove 22.

[0045] Reference Figure 3, the anti-sticking structure for the air cushion machine in this embodiment is installed on the air cushion machine body. When the heating wheel 1 and the wheel body 2 press and heat-seal the film material, the upper guide strip 6 can restrict the discharging direction of the film material, guide the film material after inflation and heat-sealing to discharge forward, guide the film material away from the heating wheel 1, and prevent the film material from adhering to the heating wheel 1. The lower guide strip 7 can also restrict the discharging direction of the film material, guide the film material after inflation and heat-sealing to discharge forward, guide the film material away from the wheel body 2, and prevent the film material from adhering to the wheel body 2.

[0046] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
