Operation principle：

As shown in figure 26, packaging Bag Material is the cylindrical film structure of two open ends, for the ease of storing and transporting, generally Packaging Bag Material is flattened and is wound in Cylindric Packaging Bag material volume 134 as shown in Figure 6, will be separated by packaging bag material volume 134 Packaging Bag Material cut into packaging bag as shown in figure 25 as Len req at the beginning of expect, then by the bottom opening expected at the beginning of packaging bag K1 Sealed, also need to after handware to be packaged is put in packaging bag for the open top expected at the beginning of packaging bag K2 to carry out heat Envelope, after the completion of whole process, is put in conveyer belt 120 and is transmitted.Now detailed packaging process is listed below：

1st, first, packaging bag material volume 134 is sheathed on transfer roller 133, control system is passed through to control transfer roller to drive electricity Machine 135 works or stops controlling rotation or the stopping of packaging bag material volume 134, and packaging Bag Material can turning with packaging bag material volume 134 Move and progressively import in feed controlling mechanism 140；

2nd, secondly, the packaging bag derived by feed controlling mechanism 140 further through guide roller 163 import to drive roll 164 with Between driven voller 165, control system controls the length of packaging Bag Material transmission by the rotation number of turns controlling drive roll 164；

3rd, because motion bar 144 can be along left sliding tray 141a upper and lower sliding with right sliding tray 142a, when position sensor 147 When the least significant end that motion bar 144 is located at left sliding tray 141a and right sliding tray 142a is detected, position sensor 147 is given and is controlled system System feedback signal, control system sends control signal to transmission roll drive motor 135 and active roll drive motor 166, now, bag Pack material volume 134 stops conveying and packaging Bag Material, and connecting gear 160 continues transmission packaging Bag Material, connecting gear 160 and packaging bag Packaging Bag Material between material volume 134 is persistently tightened up, motion bar 144 with packaging tightening up of Bag Material and along left sliding tray 141a with Right sliding tray 142a is gradually increasing, when the packaging Bag Material length that control system detects connecting gear 160 transmission is enough, again Send control signal to transmission roll drive motor 135 and active roll drive motor 166, packaging bag material volume 134 recovers conveying and packaging Bag Material, the packaging Bag Material between connecting gear 160 and packaging bag material volume 134 persistently relaxes, and motion bar 144 is with packaging Bag Material Relax and be gradually reduced, thus complete the transmission of the packaging bag material volume of single cutoff length, so move in circles, until completing to wrap The transmission of Bag Material is all packed in pack material volume 134；

4th, as shown in figure 26, packing work starts the initial stage, when control system detects the packaging bag of connecting gear 160 transmission When material is sent between the movable sealing plate 153 in bottom cutting machine structure 150 and fixing fagging 151, control system sends and controls letter Number give bottom cutting machine structure 150, the movable sealing plate driver 158,159 of bottom cutting machine structure 150 drive movable sealing plate 153 with solid Determine fagging 151 to be harmonious, cutting knife 154 completes while the cutting of lower limb a1 place to packaging Bag Material, movable sealing plate 153 and fixation Fagging 151 completes the heat-sealing at the lower limb A1 of packaging Bag Material is thus completed with cutting and heat of the bottom opening of packaging bag D1 Envelope, when the packaging Bag Material length that control system detects connecting gear 160 transmission is enough, control system sends control letter again Number give bottom cutting machine structure 150, now, the movable sealing plate driver 158,159 of bottom cutting machine structure 150 drives movable sealing plate 153 are harmonious with fixing fagging 151, and cutting knife 154 completes at the top edge a2 of packaging Bag Material while cutting, movable sealing plate 153 complete, to the heat-sealing at the top edge A2 of packaging Bag Material, thus to complete the open-topped of packaging bag D1 with fixing fagging 151 Cut and packaging bag D2 the cutting and sealing of bottom opening, so move in circles, until completing the bottoms of all packaging Bag Materials The cutting and sealing of opening；

5th, after the bottom opening packing Bag Material completes to cut and seal, send the pinch assembly 184,185 in bag mechanism 180 Packaging bag after cutting is sent to the underface of charging enclosed mechanism 170 by the underface of bottom cutting machine structure 150, this When, charging enclosed mechanism 170 in anterior sucker 175 and right sucker 176 hold packaging bag upper shed before and after both sides, clamp assembly , by both sides of the edge clamping before and after packaging bag upper shed, anterior sucker 175 and right sucker 176 are advancing slip for 177 clamping termination 177e The upper shed of packaging bag is strutted by dynamic shrouding cylinder 173a and rear slip shrouding cylinder 174a, now, handware to be packaged by Blanking channel 113 in frame 110 is transported in the feed opening 114 directly over charging enclosed mechanism 170, then by feed opening 114 put in packaging bag, and the bottom of packaging bag is then carried by the carrier 195a in carrier assembly 195, works as packaging bag In when filling enough handwares, front slide shrouding 173 and rear slip shrouding 174 in front slide shrouding cylinder 173a and rear slide It is harmonious under the driving of shrouding cylinder 174a, to complete the heat-sealing to packaging bag upper shed；

6th, after the heat-sealing of packaging bag upper shed completes, the handware after the completion of packaging is inclined by carrier 195a by upset Pour on the conveyer belt 120 immediately below carrier 195a, so far complete the single packaging of handware, so move in circles, Until completing the packaging process of all handwares.

Number of devices described herein and treatment scale are used to simplify explanation of the present utility model.To this utility model Application, modifications and variations will be readily apparent to persons skilled in the art.
