The securing mechanism 600 is used to secure a roll 900 or stack of wrappers 910 and provide the wrappers 910. The folding assembly 200 is used for folding two opposite sides of the packing material 910. The unfolding structure 400 is used to unfold two sides of the folded packaging material 910, so that the packaging material 910 can be loaded with goods to form an unsealed and uncut package 920. The conveying mechanism 300 includes a power assembly 310, the power assembly 310 is mounted on the frame 100, and the power assembly 310 is used for providing power for conveying the packing material 910. Packaging mechanism 500 is used for cutting the parcel 920 of strutting structure 400 output and heat-sealing the upper edge 921, first side 923 and the lower edge 922 of next parcel 920 of parcel 920, wherein, present parcel 920 is the parcel 920 of being encapsulated, and next parcel 920 is after present parcel 920, needs to encapsulate next time.

The packaging device fixes the packaging material roll 900 or the packaging material 910 on the fixing mechanism 600 during the packaging process, so as to stably supply the material for the packaging process; the power assembly 310 is started, so that the packing material 910 sequentially passes through the folding assembly 200 and the expanding structure 400, and the folded packing material 910 is conveyed to the packaging mechanism 500; then, the packaging mechanism 500 is started, and the folded packaging material 910 is subjected to first sealing and cutting, so that the lower edge 922 of the packaging material 910 is effectively sealed; after sealing, the goods are put into the package material 910 at the position of the spreading structure 400 to form an unsealed and uncut package 920; at this time, only the upper side 921 and the first side 923 of the package 920 are unsealed (the sealing of the second side 924 of the package 920 is completed by the folding assembly 200), and therefore, the power assembly 310 is started to convey the package 920 to the packaging mechanism 500; packaging mechanism 500 is then activated to seal and cut package 920, such that upper edge 921 of package 920, first side edge 923, and lower edge 922 of the next package 920 are heat sealed, and sealed package 920 is cut from wrapper 910, thereby obtaining a complete package 920. So, this scheme combines fixed establishment 600, fifty percent discount subassembly 200, struts structure 400 and packaging mechanism 500 organically for the automatic packing is realized to the goods, has reduced the error rate of manual packaging, guarantees the quality of packing, improves the packing efficiency of goods.

The wrapping material roll 900 is formed by rolling the wrapping material 910 around the axis, and the wrapping material 910 is stacked by folding the wrapping material 910 in a serpentine shape. Meanwhile, the package 920 of the present embodiment is a packing material 910 containing goods. The package 920 has two states, i.e., the loaded goods are not separated from the package material 910 and are not sealed; secondly, separating and sealing the packaging material 910; simultaneously, parcel 920 has four limits, is last limit 921, lower limit 922, first side 923 and second side 924 respectively, because encapsulation mechanism 500 carries out the heat-seal to last limit 921, first side 923 and the lower limit 922 of next parcel 920 of parcel 920 simultaneously, consequently, when packing plant just moved, before need drop into the goods in wrapping material 910, starts encapsulation mechanism 500 once in advance, seals once to wrapping material 910 and cuts to guarantee that the four sides of the parcel 920 of follow-up production all are in the involution state. In addition, through this packaging mechanism 500, also guarantee before throwing into the goods, the lower limb 922 of packing material 910 is all sealed, effectively avoids the goods to spill.

Specifically, power assembly 310 is positioned between folio assembly 200 and distraction structure 400. Because the packing material 910 has a certain flexibility, the power assembly 310 is disposed between the folding assembly 200 and the opening structure 400 in this embodiment, so that the packing material 910 passes through the folding assembly 200 in a pulling manner, and the packing material 910 has a certain tension on the folding assembly 200, which is beneficial to better folding the packing material 910. At the same time, the action of the power assembly 310 is prevented from damaging the cargo within the package 910 before the structure 400 is expanded.

Further, referring to fig. 2 and 5, the power assembly 310 includes a first driving member 313, and a driving roller 311 and a driven roller 312 rotatably mounted on the frame 100. The driving roller 311 is connected with an output shaft of the first driving member 313, the driving roller 311 is in transmission connection with the driven roller 312, and the side surface of the driving roller 311 is in interference fit with the side surface of the driven roller 312 for clamping the folded packing material 910. Therefore, when the action component operates, the first driving component 313 drives the driving roller 311 to rotate on the frame 100, and since the driving roller 311 is in transmission connection with the driven roller 312, the rotating driving roller 311 drives the driven roller 312 to rotate together. Since the side surface of the drive roller 311 and the side surface of the driven roller 312 are in contact engagement with each other, the packing 910 sandwiched between the drive roller 311 and the driven roller 312 is stably conveyed by the rotation of the two.

Specifically, the transmission connection between the drive roller 311 and the driven roller 312 is in meshing connection with a gear through a gear. Meanwhile, the connection between the first driving member 313 and the driving roller 311 may be a gear-to-gear, a transmission belt, or a transmission chain. The first driving member 313 is a motor.

In one embodiment, referring to fig. 3 and 4, the packaging apparatus further includes a deviation correcting mechanism 700 mounted on the frame 100. The folding assembly 200 is mounted on the deviation correcting mechanism 700. The deviation rectifying mechanism 700 is used for rectifying the deviation of the packing material 910 and outputting the packing material 910 to the folding assembly 200. Thus, through the deviation rectifying mechanism 700, the package material 910 can automatically return, the deviation rectifying function of the package material 910 can be effectively realized, and the package effect of goods can be guaranteed.

Further, referring to fig. 5, the folding assembly 200 includes a first folding member 210 and a second folding member 220 mounted on the deviation correcting mechanism 700. The free end of the first folio part 210 is connected with or close to the free end of the second folio part 220. The first folding member 210 and the second folding member 220 are both disposed obliquely relative to the power assembly 310, and the free ends of the first folding member 210 and the second folding member 220 are closer to the power assembly 310 than the connecting ends of the first folding member 210 and the second folding member 220. Therefore, the first folio part 210 and the second folio part 220 are in or approximately in an inclined herringbone structure, and in the actual operation process, one side of the packing material 910 bypasses the first folio part 210; the other side of the packing material 910 is wound around the second folding member 220, and the two wound sides are attached again, at this time, the middle portion of the packing material 910 is supported by the first folding member 210 and the second folded free end, so that the packing material 910 is folded on the folding assembly 200.

It should be noted that the free end of the first folio part 210 is connected to or close to the free end of the second folio part 220, and it should be understood that: the first folding part 210 and the second folding part 220 form an included angle, and the free end of the first folding part 210 and the free end of the second folding part 220 may or may not be connected. The free ends of the first folded part 210 and the second folded part 220 are opposite to the deviation rectifying mechanism 700.

Meanwhile, the first folding member 210 and the second folding member 220 are both disposed obliquely with respect to the axial direction of the driving roller 311.

Further, referring to fig. 3 and 5, the folding element 200 further includes an adjusting member 260 mounted on the deviation correcting mechanism 700. The first folder 210 and the second folder 220 are both rotatably mounted on the deviation correcting mechanism 700. The adjusting member 260 is used for adjusting the rotation angle of the first folding member 210 and the second folding member 220, so that the inclination angles of the first folding member 210 and the second folding member 220 can be adjusted by the adjusting member 260 to compensate for the angle deviation caused by machining and installation.

Specifically, the adjusting member 260 is a threaded rod, the deviation correcting mechanism 700 is provided with an adjusting nut, the cross rod 250 is connected between the first folding member 210 and the second folding member 220, one end of the threaded rod is screwed into the adjusting nut, and the other end of the threaded rod is connected with the cross rod 250.

In one embodiment, referring to fig. 5, the folio assembly 200 further includes a transport roller 240 and a carrier 230. The transfer roller 240 is connected to the carrier 230 at a distance between the first folder 210 and the second folder 220. In this way, in the process of folding, the packing material 910 is wound around the upper side of the conveying roller 240 and penetrates out from between the conveying roller 240 and the carrier 230, and then, the two opposite sides of the packing material 910 are respectively wound around the first folding member 210 and the second folding member 220 to be folded.

In one embodiment, referring to fig. 5, the folding assembly 200 further includes a first pre-clamping roller 270 and a second pre-clamping roller 280 rotatably mounted on the frame 100, the first pre-clamping roller 270 and the second pre-clamping roller 280 are both located between the first folding member 210 and the power assembly 310, and a side surface of the first pre-clamping roller 270 and a side surface of the second pre-clamping roller 280 are in interference fit for clamping the folded package 910, so as to ensure that the folded package 910 is well formed.

In one embodiment, referring to fig. 6, the deviation correcting mechanism 700 includes a deviation correcting frame 710, a first guide roller 720, a second guide roller 730, a deviation correcting assembly 740, a first sensor 750 and a second driving member, the first guide roller 720 and the second guide roller 730 are arranged in parallel and are both rotatably installed on the deviation correcting frame 710, the deviation correcting assembly 740 is located between the first guide roller 720 and the second guide roller 730 and can swing back and forth along the axial direction of the first guide roller 720, the deviation correcting assembly 740 and the second guide roller 730 are sequentially wound around the wrapping material 910, the first sensor 750 is installed on the deviation correcting frame 710, the first sensor 750 is used for obtaining the deviation amount of the wrapping material 910, the second driving member is electrically connected to the first sensor 750, and the output shaft of the second driving member is in driving fit with the deviation correcting assembly 740.

In the above-mentioned deviation rectifying mechanism 700, during the packaging process, one end of the wrapping material 910 is sequentially wound around the first guide roller 720, the deviation rectifying assembly 740 and the second guide roller 730, so that the wrapping material 910 is stably wound around the deviation rectifying mechanism 700, and the wrapping material 910 can be continuously conveyed on the deviation rectifying mechanism 700. Because the deviation rectifying frame 710 is provided with the first sensor 750, when the package material 910 deviates in the conveying process, the first sensor 750 obtains the deviation amount of the package material 910, and triggers the second driving member to act, so as to drive the deviation rectifying assembly 740 to correspondingly swing along the axial direction of the first guide roller 720, and drive the package material 910 to swing along the direction opposite to the deviation, so that the deviation amount of the package material 910 on the deviation rectifying mechanism 700 is effectively offset, the package material 910 output on the second guide roller 730 automatically returns, the deviation rectifying function of the package material 910 is effectively realized, and the packaging effect of the goods is favorably ensured.

It should be noted that the deviation correcting assembly 740 can swing back and forth along the axial direction of the first guide roller 720, which is understood as follows: the deskew assembly 740 is capable of yaw left and right on the deskew frame 710. The deviation correcting assembly 740 can be located above the first guide roller 720 and the second guide roller 730; and may also be positioned below the first guide roller 720 and the second guide roller 730. When the deviation rectifying assembly 740 is located below the first guide roller 720 and the second guide roller 730, the deviation rectifying assembly 740 may be suspended in the deviation rectifying frame 710, or may be configured to swing on the deviation rectifying frame 710. In actual operation, the wrapping material 910 is wound and suspended.

Specifically, referring to fig. 6, the deviation rectifying assembly 740 is located below the first guide roller 720 and the second guide roller 730, and the deviation rectifying assembly 740 is suspended in the deviation rectifying frame 710.

It should be noted that the second driving member is electrically connected to the first sensor 750, which is to be understood as the second driving member is indirectly connected to the first sensor 750. For example, the second driving member is indirectly electrically connected to the first sensor 750 through the control system, and during the deviation correction process, the first sensor 750 detects the operation state of the packing material 910 and obtains the offset of the packing material 910, if the packing material 910 is detected to be offset, the offset information is generated to the control system, and after the control system obtains the information, the control system controls the second driving member to perform corresponding actions.

For this reason, the present embodiment provides two types of sensors, and obtains the stitching status information of the first stamper 540 and the third stamper 560 through the second sensor 581; then, the third sensor 5231 obtains the moving information of the first protection cover 523 along the direction away from the second protection cover 533, so that when the cargo is just at the pressing position, the first protection cover 523 contacts the cargo before the first pressing die 540, and moves along the direction away from the second protection cover 533 under the collision of the cargo, so that the third sensor 5231 cooperates with the sensing piece 5221 and sends out a detection signal, and at this time, because the first pressing die 540 and the third pressing die 560 are not pressed, the second sensor 581 does not detect the information, so it is determined that the sealing and cutting structure is clamped to the cargo, at this time, the first support 520 and the second support 530 are controlled to be away from each other, and the pressing operation is stopped. Of course, when the third sensor 5231 detects information and sends a signal, and the second sensor 581 also detects information, it indicates that the sealing and cutting structure is operating normally.

It should be noted that the elastic movement of the first protection cover 523 on the first support 520 is understood as: the first protection cover 523 moves on the first support 520, and after moving, it can be rebounded to the initial position under the elastic action. In a specific installation manner, an elastic structure such as a spring, a torsion spring, elastic rubber, or the like may be disposed between the first protective cover 523 and the first bracket 520.
