After the end of the packaging bag and the rubber strip are blown up by the bag sealing air blowing seat, the rubber strip is folded at the side pressing support rod through the bag sealing push roller and the rubber strip is adhered to the packaging bag. After the bag sealing is completed, the packaged socks can also be transferred to the next process through the transfer device.

The packaging bag I is transferred between the adhesive tape tearing mechanism B and the bag loading mechanism C through the second transfer suction cup assembly. The packaging bag I is transferred between the bag loading mechanism C and the bag sealing mechanism D through the third transfer suction cup assembly.

[0096] Specifically, the working process of this sock bagging machine is successively to take the packaging bag I, tear off the adhesive tape I1 on the packaging bag I, put the socks into the packaging bag I, and seal the packaging bag I with the adhesive strip I2.

[0097] The process of taking the packaging bag I is as follows: Place the packaging bag I in the bagging bin A1 formed by two symmetrically arranged long baffles A17 and two symmetrically arranged short baffles A18. Press the pressing plate on the topmost packaging bag I so that the lowermost packaging bag I contacts the bin supporting wheel A15. Drive the bag-taking bracket A22 to rise through the bag-taking cylinder A21, so that the bag-taking suction cup A23 sucks the lowermost packaging bag I. Drive the bag-taking bracket A22 to descend through the bag-taking cylinder A21, and pull the lowermost packaging bag I out of the bagging bin A1 between the two bin supporting wheels A15. The bin supporting wheel A15 is provided to reduce the friction between the bagging bin A1 and the packaging bag I, facilitating the pulling out of the packaging bag I.

[0098] The process of tearing off the sticker I1 on the packaging bag I is as follows: After taking out the packaging bag I, suck the packaging bag I by rising the lifting cylinder E6 in the first transfer suction cup assembly. Drive the transfer sliding frame E2 to move on the transfer fixed frame E1 through the transfer sliding cylinder E5, and place the packaging bag I under the bag-pressing device B1; when the packaging bag I is placed under the bag-pressing device B1, drive the bag-pressing base B13 to move downward through the bag-pressing cylinder B12, and press the packaging bag I tightly on the substrate F through the provided bag-pressing block B14 and bag-pressing plate B15. The bag-pressing spring B17 is provided to keep the bag-pressing block B14 and bag-pressing plate B15 in contact with the packaging bag I all the time. Blow up the edge of the sticker I1 of the packaging bag I through the paper-clamping air valve B33, control the movement of the paper-clamping block B32 through the paper-clamping cylinder B31, so that the blown-up sticker I1 is clamped between the first chuck B34 and the second chuck B35. Drive the sticker-tearing base B22 to move through the sticker-tearing cylinder B21, tear off the sticker I1 clamped between the first chuck B34 and the second chuck B35, and place the torn-off sticker I1 in the sticker-tearing trough B23. Thus, the tearing off of the sticker I1 on the packaging bag I is completed.

[0099] The process of loading the socks into the packaging bag I is as follows: After tearing off the adhesive tape I1 on the packaging bag I, the lifting cylinder E6 in the second transfer suction cup assembly rises to suck the packaging bag I. The transfer sliding cylinder E5 drives the transfer sliding frame E2 to move on the transfer fixing frame E1, and places the packaging bag I below the bag suction device C1 and the positioning device C3. With the packaging bag I placed below the bag suction device C1 and the positioning device C3, the positioning cylinder C32 drives the positioning pressure plate C33 to move downward, so that the two positioning heads C35 press the left and right side edges of the packaging bag I on the substrate F. The bag suction cylinder C12 drives the upper bag suction suction cup C13 to move downward. The upper bag suction suction cup C13 and the lower bag suction suction cup C14 provided respectively suck and combine the upper and lower sides of the packaging bag I. At this time, the bag suction cylinder C12 drives the upper bag suction suction cup C13 to move upward, and the opening of the packaging bag I can be opened in the up and down directions. The bag opening moving cylinder C21 drives the bag opening cylinder C22 to move forward, so that the bag opening guide frame C23 is inserted into the opening of the packaging bag I. The bag opening cylinder C22 drives the two bag opening guide frames C23 to move outward, and the opening of the packaging bag I can be opened in the left and right directions. The upper clamping cylinder C45 and the lower clamping cylinder C46 respectively drive the upper clamping plate C43 and the lower clamping plate C44, so that the upper clamping plate C43 and the lower clamping plate C44 clamp the socks. The sock clamping moving module C41 drives the sock clamping moving frame C42 to move, so that the upper clamping plate C43 and the lower clamping plate C44 pass through the bag opening guide groove C24 formed by the two bag opening guide frames C23, and place the socks in the packaging bag I. Thus, the process of loading the socks into the packaging bag I can be completed.

[0100] The process of sealing the packaging bag I with the adhesive strip I2 is as follows: After the socks are loaded into the packaging bag I, the lifting cylinder E6 in the third transfer suction cup assembly rises to suck the packaging bag I. The transfer sliding cylinder E5 drives the transfer sliding frame E2 to move on the transfer fixed frame E1, and places the packaging bag I under the pressing device D1; The packaging bag I containing socks is placed under the pressing device D1. The pressing cylinder D12 drives the pressing block D13 to press the opening of the packaging bag I tightly on the substrate F. The side pressure telescopic cylinder D33 drives the side pressure support rod D34 to extend, and the side pressure lifting cylinder D32 drives the side pressure telescopic cylinder D33 to move downward, so that the side pressure support rod D34 presses between the adhesive strip I2 of the packaging bag I and the opening of the packaging bag I. The sealing bag blowing seat D27 blows air upward to make the adhesive strip I2 and the end of the packaging bag I blow upward and warp. The sealing bag cylinder D21 drives the sealing bag support D22, and the sealing bag push roller D24 pushes the warped end of the packaging bag I, and makes the warped end of the packaging bag I fold at the side pressure support rod D34. Thus, the adhesive strip I2 can be pasted on the packaging bag I. The provided sealing bag torsion spring D25 can drive the sealing bag push roller D24 to always be in tight contact with the substrate F, so that the folded adhesive strip I2 can be pressed tightly on the packaging bag I. Thus, the sealing of the packaging bag I is completed. After the sealing is completed, after the side pressure support rod D34, the sealing bag push roller D24, and the pressing block D13 are reset, the transfer lifting cylinder D42 is driven to drive the transfer suction cup support D44 to move downward. The transfer suction cup D43 sucks the packaging bag I containing socks after sealing, and the transfer rotating cylinder D41 transfers the socks to the next station.
