[0126] The folding of the bag opening of the tote bag is an important link in the production process of the tote bag. It not only can increase the aesthetic degree of the tote bag, but also can improve the practicability and durability of the tote bag. Specifically, the tote bag with folded edge is more solid and not easy to deform, which can better maintain the shape of the tote bag. Moreover, through the folding treatment, the bag opening part of the tote bag is strengthened, thereby improving the load-bearing capacity of the tote bag. In addition, the folding can make the edge of the bag opening of the tote bag more neat and beautiful, and improve the overall visual effect. However, the procedure of folding the bag opening inside is complex, and in the traditional production process, the procedure of folding and bonding the bag opening inside is still completed by hand, which has high labor cost and low production efficiency.

[0127] Of course, in the prior art, there is also a device for folding the bag opening inside by inserting a plate. In order to fold the bag opening inside, the tote bag must be completely unfolded, which increases the complexity and time cost of the operation. Moreover, the unfolded tote bag will occupy more space, especially when a large number of tote bags are processed, this problem is particularly prominent. In addition, the unfolded tote bag is not easy to be quickly and neatly stored, which may bring difficulties to the subsequent storage and management work, thereby greatly affecting the production efficiency of the tote bag.

[0128] Therefore, the utility model provides a bag opening folding device for tote bag production equipment, this bag opening folding device includes frame and transport component which is arranged on frame, still be provided with traction component, bag opening outer folding component, folding edge glue spraying component, bag opening inner folding component and folding edge pressing component which are arranged in turn along the conveying channel of transport component on frame, traction component places outside tote bag in folding posture in transport component, transport component linkage tote bag passes through traction component, bag opening outer folding component, folding edge glue spraying component, bag opening inner folding component and folding edge pressing component in turn, make tote bag complete bag opening folding process in folding posture, and, the tote bag which completes whole bag opening folding process still is in folding posture, convenient for the storage and transportation of finished product tote bag, improve the production efficiency of tote bag.

[0129] In order to make the purpose, technical scheme and advantage of the utility model more clear, the embodiment of the utility model will be described in further detail below in conjunction with the drawings.

[0130] To facilitate the description of the working principle of the bag opening hemming device, the overall structure of the tote bag will be described first.

[0131] As shown in Figure 1 , the tote bag 10 includes a bottom surface 110, a pair of first side surfaces 120 extending along a first direction Y and arranged opposite to each other, and a pair of second side surfaces 130 extending along a second direction X and arranged opposite to each other, each first side surface 120 has two side edges in the first direction Y connected with respective edges of the pair of second side surfaces 130, and the tote bag 10 can be folded along the respective center lines of the pair of second side surfaces 130. Moreover, in order to improve the strength of the bag opening of the tote bag 10, a bag opening hem 140 can be provided at the bag opening of the tote bag 10, and a predetermined hem crease 150 extending around the tote bag 10 can be formed at the lower side of the bag opening edge of the tote bag 10, and the bag opening of the tote bag 10 can be folded inward along the predetermined hem crease 150 to strengthen the strength of the bag opening of the tote bag 10.

[0132] The tote bag 10 can be made of any one of non-woven fabric, paper material or paper-like material, and the present application does not make a unique limitation thereto.

[0133] The non-woven fabric has high durability due to its fiber interlaced structure and can withstand a certain degree of stretching and tearing. For occasions that require high durability and environmental friendliness, non-woven fabric material can be selected. The paper material has good printing performance and can easily print various characters, patterns and logos, and has low cost. For occasions that focus on cost-effectiveness and printing performance, paper material or paper-like material can be selected to meet different use requirements. It should be noted that Figure 1 The handle of the tote bag 10 is not shown in the figure, and in fact, the two ends of the handle are fixed between the bag opening hem 140 and the first side surface 120 to ensure the connection strength between the handle and the bag body. Of course, the connection mode between the handle and the bag body can be designed by the person skilled in the art according to the actual situation and specific requirements, and the present embodiment does not make a specific limitation thereto.

[0134] The specific structure and working principle of the bag opening hemming device will be described below.

[0135] In the tote bag production equipment, the sheet-shaped base material (such as paper material) cut and formed will be transported to the lower side of the mold and extruded by the mold to form the shape of the bag body (such as the cuboid shown in Figure 1 , and further, in order to reduce the occupied space of the bag body, the unfolded tote bag 10 will pass through the bag folding device and be compressed and folded. At this time, the basic bag body of the tote bag 10 is formed, and in order to further strengthen the strength of the bag opening of the tote bag 10, the bag opening of the tote bag 10 needs to be folded inward to form the bag opening hem 140. Therefore, the bag body output from the bag folding device needs to be sent into the bag opening hemming device provided by the present application.

[0151] The specific structure and working principle of the conveying component 200 will be described below.

[0152] As shown in Figure 3 The conveying component 200 includes a pair of conveying belts 210 arranged on the table surface of the rack 100 and spaced apart along the second direction X, and the lower end of the pair of conveying belts 210 is attached to the table surface of the rack 100. Among them, the table surface of the rack 100 refers to the middle part of the rack 100 in the vertical direction, which forms a platform for fixing the conveying component 200.

[0153] A conveying channel is formed between the pair of conveying belts 210, and the inlet end of the conveying channel is a "V" type inlet, and the width of the inlet end of the conveying channel downstream is matched with the thickness of the handbag 10 in the folded state. It should be noted that the inside of the pair of conveying belts 210 forms a transmission wheel 220, which is connected with a transmission motor. When the transmission motor drives the transmission wheel 220 to rotate, the pair of conveying belts 210 move from the inlet end to the outlet end of the conveying channel along the first direction Y on the wall surface facing each other.

[0154] Moreover, the inside of the pair of conveying belts 210 and the wall surface facing each other are also provided with a plurality of tensioning wheels 230, which abut on the wall surface of the conveying belt 210, so that the conveying belt 210 is in a taut state, thereby preventing the conveying belt 210 from slipping relative to the first side surface 120 of the handbag 10 during movement.

[0155] Moreover, the side of the conveying belt 210 is also provided with a jitter prevention plate 240 to prevent the conveying belt 210 from shaking, the jitter prevention plate 240 is installed on the rack 100, and the jitter prevention plate 240 has an extension plate extending in the horizontal direction and abutting on the side edge of the conveying belt 210, thereby limiting the jitter of the conveying belt 210 and ensuring the stability of the conveying process. The specific structure of the jitter prevention plate 240 is not limited in this embodiment.

[0156] The pair of conveying belts 210 arranged along the folding direction of the transport component 200 can drive the carrier bag 10 to move, and the conveying channel with the "V" type entrance can guide the carrier bag 10 to move in the second direction X until the interval between the pair of conveying belts 210 is suitable for the thickness of the carrier bag 10 in the folded state, so that the folded state of the carrier bag 10 can be maintained during the transportation. In the vertical direction, the lower end of the pair of conveying belts 210 is attached to the upper surface of the table, and the table of the rack 100 can assist in supporting the carrier bag 10 when the pair of conveying belts 210 is used to transport the carrier bag 10, so as to avoid the carrier bag 10 from shaking in the vertical direction.

[0157] In addition, at the entrance end of the conveying channel, an adjusting component for adjusting the interval between the pair of conveying belts 210 is arranged, and the adjusting component has a sliding groove extending along the second direction X, and the lower edge of the pair of conveying belts 210 has a sliding block matched with the sliding groove. By adjusting the interval between the sliding blocks of the pair of conveying belts 210 in the sliding groove, the interval between the pair of conveying belts 210 at the exit end can be changed. The specific structure of the adjusting component is not uniquely limited in the utility model.

[0158] The specific structure and working principle of the traction component 300 will be described below.

[0159] As shown in Figure 4 The traction component 300 includes a guide rail 320 arranged on the rack 100 and extending along the first direction Y, and a jaw driving member 330 in driving connection with the jaw 310. The jaw 310 is slidably arranged on the guide rail 320, and the jaw driving member 330 drives the jaw 310 to move along the guide rail 320.

[0160] The jaw 310 is arranged as a fixed plate 311 and a movable plate 312 arranged along the second direction X, and a clamping driving member 313 in driving connection with the movable plate 312 and capable of driving the movable plate 312 to move along the second direction X. The bottom end of the fixed plate 311 has a supporting portion extending along the horizontal direction. The clamping driving member 313 can be arranged as a motor and fixed to the supporting portion of the fixed plate 311, and the bottom of the supporting portion is slidably connected to the guide rail 320. The jaw driving member 330 is arranged as a pneumatic cylinder, and the output end of the pneumatic cylinder has a tank chain extending along the first direction Y. The supporting portion of the movable plate 312 is connected to the tank chain. When the clamping driving member 313 drives the tank chain to move along the first direction Y, the jaw 310 is driven to move along the guide rail 320.

[0161] Specifically, the clamping jaw 310 is arranged as a fixed plate 311 and a movable plate 312 which are arranged at intervals along the second direction X, the clamping driving member 313 drives the movable plate 312 to move towards the fixed plate 311, and clamps the bag opening edge of the handbag 10, so as to avoid the handbag 10 from being opened from the bag opening. Then, the clamping jaw 310 moves along the guide rail 320 which extends along the first direction Y under the action of the clamping jaw driving member 330, so as to ensure that the handbag 10 can be moved to the inlet end of the conveying channel in the folded posture.

[0162] The specific structure of the bag opening folding member 400 will be described below.

[0163] As shown in the drawings, in the embodiment, the bag opening folding member 400 comprises a folding assembly 410, a first opening assembly 420 and an auxiliary folding assembly 430.

[0164] The connecting plate 413 extending along the horizontal direction is connected to the folding driving member 414, so as to ensure the stability of the connection between the folding plate 411 and the folding driving member 414, and the vertical plate 412 extending along the vertical direction is capable of pushing the bag opening folding edge outward when the folding plate 411 moves downward along the vertical direction.

[0165] Optionally, in another embodiment, a transverse air cylinder 415 is arranged between the pair of folding plates 411, the transverse air cylinder 415 is arranged at the output end of the folding driving member 414, and the two ends of the transverse air cylinder 415 along the second direction X are connected to the connecting plates 413 of the corresponding folding plates 411 respectively, so as to drive the pair of folding plates 411 to move towards or away from each other along the second direction X.

[0166] Of course, in another alternative embodiment, the pair of folding plates 411 can also be an integral structure, the vertical plates 412 of the two folding plates 411 are arranged at intervals along the horizontal direction and are connected by the connecting plate 413 extending along the horizontal direction, and in this case, the transverse air cylinder 415 is not required to be arranged between the pair of folding plates 411, and the present application is not limited to this.

[0167] In the present embodiment, as shown in Figure 7 The pair of first suction members 421 of the first opening assembly 420 includes a pair of first swing arms 422 and a first mounting bracket 423 arranged at the upper end of the first swing arms 422, and a plurality of first suction nozzles 424 are arranged at the first mounting bracket 423 along the first direction Y. The number of the first suction nozzles 424 can be two, three, four, five, six or other numbers, which are not uniquely limited in the present embodiment.

[0168] In an embodiment, as shown in Figure 6 The first opening assembly 420 further includes a first base 425 arranged on the rack 100 below the handbag 10 in the conveying channel, the lower ends of the first swing arms 422 of the pair of first suction members 421 intersect below the conveying channel and are hinged to the first base 425, and the lower ends of the pair of first swing arms 422 are provided with first transmission gears 426 engaged with each other.

[0169] A first swing arm driving member 427 is arranged on one side of the first base 425 along the second direction X, and the first swing arm driving member 427 is in transmission connection with the first swing arm 422 on the one side of the second direction X and drives the pair of first swing arms 422 to swing towards or away from each other around the respective lower ends. The output end of the first swing arm driving member 427 is provided with an intermediate linkage wheel, the first linkage rod is eccentrically hinged on the intermediate linkage wheel, and the other end of the first linkage rod is hinged to the lower side of the first swing arm 422.

[0170] As shown in Figure 6 In an embodiment, the auxiliary outer folding assembly 430 includes two pairs of first auxiliary pressing plates 431 arranged along the first direction Y, and each pair of first auxiliary pressing plates 431 is arranged on the two sides of the bag opening of the handbag 10 in the conveying channel in the second direction X. In the first direction Y, the two pairs of first auxiliary pressing plates 431 are respectively aligned with the inner sides of the two ends of the first side surface 120, and in the vertical direction, the upper edge of the first auxiliary pressing plate 431 is flush with the predetermined folding crease 150 at the upper end of the first side surface 120. Of course, the auxiliary outer folding assembly 430 can also be provided with three pairs of first auxiliary pressing plates 431 or other pairs of first auxiliary pressing plates 431, which are not uniquely limited in the present embodiment.

[0171] It should be noted that in order to enable the two pairs of first auxiliary pressing plates 431 to clamp the handbag 10 of different bag types, the two pairs of first auxiliary pressing plates 431 are arranged in the adjusting sliding grooves extending along the first direction Y, and the spacing between the two first auxiliary pressing plates 431 on the same side is adjusted to adapt to the width of the first side surface 120 of the handbag 10.

[0172] Furthermore, on the frame 100, an auxiliary outward folding drive 432 is provided on the side of each first auxiliary pressure plate 431 away from the conveying channel. The auxiliary outward folding drive 432 is connected to a corresponding first auxiliary pressure plate 431 and moves the first auxiliary pressure plate 431 along the second direction X in conjunction with it.

[0173] When the tote bag 10 is vertically pushed and squeezed by a pair of outer push plates 411, and then bent outward at an angle greater than 90 degrees, the two pairs of first auxiliary pressure plates 431, which are spaced apart along the first direction Y, move toward the outwardly folded bag opening edge 140 under the drive of the auxiliary outward folding drive member 432, and fit tightly against the corresponding bag opening edge 140 of the tote bag 10, thereby applying an outward force to the bag opening part of the tote bag 10, ensuring that the bag opening edge 140 of the tote bag 10 can be folded outward neatly and in a standardized manner.

[0174] Optionally, such as Figure 7 As shown, in one embodiment, the bag opening folding component 400 further includes a pre-compression component 440 on both sides of a pair of first side surfaces 120 of the tote bag 10, which is movably disposed in the conveying channel along the second direction X. The pre-compression component 440 is located outside the pair of first side surfaces 120 in the second direction X, and in the vertical direction, the pre-compression component 440 is lower than the first suction component 421.

[0175] In this process, the lower end of one pair of outward push plates 411 moves vertically into the tote bag 10 whose opening is sucked in by a pair of first suction components 421. The pair of first suction components 421 release the first side 120 of the tote bag 10, and the pre-pressing component 440 moves along the second direction X toward the corresponding first side 120 so that the inner walls of the pair of first side 120 fit together. The outward push plates 411 continue to push the upper edge of the first side 120 vertically downward, and the first auxiliary pressure plate 431 moves along the second direction X so that the upper part of the first side 120 bends downward along the predetermined fold line 150 to form the bag opening fold 140.

[0176] When the lateral cylinder 415 is arranged between the pair of the outward pushing plates 411, the pre-pressing assembly 440 moves along the second direction X towards the corresponding first side face 120, so that the inner walls of the pair of the first side faces 120 are attached to each other, the lateral cylinder 415 can drive the pair of the outward pushing plates 411 to move in the second direction X in opposite directions, push the bag opening flaps 140 outward along the second direction X, and better make the bag opening flaps 140 of the first side face 120 outward fold along the predetermined bag opening crease 150 by less than ninety degrees. When the pair of the outward pushing plates 411 continue to vertically push the upper part of the first side face 120 downward, and the lateral cylinder 415 drives the pair of the outward pushing plates 411 to move in the second direction X in opposite directions, push the bag opening flaps 140 inward along the second direction X, so that the bag opening flaps 140 of the first side face 120 outward fold along the predetermined bag opening crease 150 by more than ninety degrees, so that the outward pushing plates 411 better push the bag opening flaps 140 outward.

[0177] Therefore, the bag opening outward folding component 400 provided by the embodiment can make the pair of the first suction components 421 relax the first side face 120 of the tote bag 10, and then the pre-pressing assembly 440 moves along the second direction X towards the corresponding first side face 120, so that the inner walls of the pair of the first side faces 120 are attached to each other, and ensure that the tote bag 10 can return to the folded state, and then when the outward pushing plates 411 continue to vertically push the upper end edge of the first side face 120 downward, the bag opening flaps 140 can accurately outward fold along the predetermined bag opening crease 150.

[0178] Optionally, in an embodiment, the pre-pressing assembly 440 includes two pairs of pre-pressing cylinders 441 arranged at intervals along the first direction Y, and each pair of the pre-pressing cylinders 441 is oppositely arranged outside the pair of the first side faces 120 of the tote bag 10 in the conveying channel in the second direction X.

[0179] Each pre-pressing cylinder 441 has an output end facing the conveying channel, and the output end has a pressing head 442, which is below the predetermined bag opening crease 150 on the first side face 120 in the vertical direction.

[0180] It should be noted that in order to enable the two pairs of the pre-pressing cylinders 441 to clamp different bag-shaped tote bags 10, the two pairs of the pre-pressing cylinders 441 are arranged in the adjusting sliding grooves extending along the first direction Y, and the spacing between the two adjusting pre-pressing cylinders 441 on the same side is adjusted to adapt to the width of the first side face 120 of the tote bag 10.

[0181] The pressing head 442 of the pre-pressing cylinder 441 can well clamp the first side face 120 of the tote bag 10, and does not have a large contact area with the first side face 120 of the tote bag 10, thereby avoiding damage to the bag body.

[0182] Of course, the specific structure of the bag mouth outer folding member 400 is not limited to the structure in the above embodiment, and can be designed according to actual conditions and specific requirements by those skilled in the art, and the embodiment does not make specific limitations.

[0183] The working process of the bag mouth outer folding member 400 on the handbag 10 will be described below.

[0184] When the handbag 10 is clamped by the clamping jaw 310 of the traction member 300 and placed on the conveying member 200, the handbag 10 is conveyed to the corresponding position of the pair of first suction members 421 by the pair of conveying belts 210, the first swing arm driving member 427 drives the pair of first swing arms 422 to swing towards each other around the lower ends thereof, so that the plurality of first suction nozzles 424 on the first mounting bracket 423 approach the first side surface 120 of the handbag 10. At this time, the plurality of first suction nozzles 424 suck and adsorb the first side surface 120. Further, the first swing arm driving member 427 drives the pair of first swing arms 422 to swing away from each other around the lower ends thereof under the action of the suction force of the plurality of first suction nozzles 424, so that the upper portions of the pair of side surfaces are opened by a predetermined angle (for example, thirty degrees). At this time, the outer pushing driving member 414 drives the pair of outer pushing plates 411 to move vertically downward, so that the pair of outer pushing plates 411 extend into the bag mouth, and the lower edges of the pair of outer pushing plates 411 are higher than the predetermined fold line 150 of the first side surface 120 in the vertical direction.

[0185] When the pair of outer pushing plates 411 extend into the bag mouth of the handbag 10 in the vertical direction, the plurality of first suction nozzles 424 on the pair of first mounting brackets 423 stop sucking, and the pair of first side surfaces 120 of the handbag 10 are folded under the action of the elasticity thereof. The inner surface of the first side surface 120 will be in contact with the outer pushing plate 411 during the folding process, and is pushed by the outer pushing plate 411 to be folded outward along the predetermined fold line 150 by less than ninety degrees.

[0186] Further, during the folding process of the pair of first side surfaces 120, the two pairs of pre-pressing cylinders 441 arranged outside the second direction X move towards the pair of first side surfaces 120 by driving the pressing head 442 and act on the upper portions of the first side surfaces 120, so as to accelerate the folding degree of the pair of first side surfaces 120, and until the pressing head 442 completely presses the first side surfaces 120, so as to ensure that the upper portions of the first side surfaces 120 can be folded outward along the predetermined fold line 150.

[0187] Subsequently, the outer pushing driving member 414 drives the pair of outer pushing plates 411 to continue moving vertically downward, and the bag mouth fold edge 140 of the pair of first side surfaces 120 continues to be folded outward under the action of the outer pushing plate 411, until the included angle with the vertical direction is close to ninety degrees. At this time, the pressing head 442 of the pre-pressing cylinder 441 is withdrawn.

[0188] In order to increase the outward folding speed of the bag opening fold 140, when the upper part of the first side 120 moves outward at less than 90 degrees along the predetermined fold line 150, the transverse cylinder 415 disposed between a pair of outer push plates 411 can move in conjunction with the pair of outer push plates 411 in opposite directions along the second direction X, and apply a force to the first side 120 in the second direction X towards the outside.

[0189] The outward push drive 414 continues to move the outward push plate 411 vertically downward, causing the bag opening fold 140 of the first side 120 to fold outward at an angle greater than 90 degrees along the predetermined fold line 150. Furthermore, the transverse cylinder 415 can move the outward push plate 411 in opposite directions along the second direction X, applying a force to the first side 120 inward along the second direction X, further causing the bag opening fold 140 of the first side 120 to fold outward.

[0190] At the same time, the auxiliary outward folding drive 432 drives the first auxiliary pressure plate 431 to move toward the outward folded edge 140 of the bag opening, so that the bag opening edge 140 is tightly attached to the corresponding outer surface of the first side 120, thus completing the outward folding of the bag opening.

[0191] Finally, the auxiliary outward folding drive component 432 retracts in conjunction with the first auxiliary pressure plate 431, and a pair of outer push plates 411 reset. The tote bag 10 moves toward the folding and glue spraying component 500 under the drive of the transport component 200.

[0192] The specific structure of the folded edge adhesive spraying component 500 is described below.

[0193] like Figure 8 As shown, in this embodiment, a pair of glue spray heads 510 are located on the outer side of the bag opening on the corresponding side in the second direction X. The frame 100 is provided with a slide rail 103 extending along the first direction Y at the corresponding position of the glue spray head 510. The glue spraying component also includes a glue spraying mounting seat 511 corresponding to and assembled with the glue spray head 510. The lower part of the glue spraying mounting seat 511 is slidably connected to the slide rail 103.

[0194] Furthermore, the frame 100 is also provided with a glue spraying drive 530 and a drive belt 531 that is connected to the glue spraying drive 530 and extends along the second direction X. The glue spraying mounting base 511 is connected to the drive belt 531.

[0195] Among them, the glue spraying drive component 530 drives the transmission belt 531 to move, and the glue spraying mounting base 511 moves along the slide rail 103 in the first direction Y. The glue spraying head 510 sprays glue onto the bag opening fold 140 that is pressed and attached to the outer wall of the first side 120 by the auxiliary pressing component 520.

[0196] Optionally, in another embodiment, the glue spraying component further comprises an auxiliary pressing assembly 520 movably arranged in the conveying channel horizontally outside the bag opening of the handbag 10 in the second direction X.

[0197] The auxiliary pressing assembly 520 moves along the second direction X towards the corresponding first side face 120, so that the folded bag opening hem 140 is attached to the outer wall of the first side face 120.

[0198] The auxiliary pressing assembly 520 can make the folded bag opening hem 140 attached to the outer wall of the first side face 120, ensuring that the bag opening hem 140 of the pair of first side faces 120 is in a consistent and stable state during the glue spraying process, ensuring the accuracy and stability of the glue spraying.

[0199] Specifically, the auxiliary pressing assembly 520 comprises two pairs of second auxiliary pressing plates 521 arranged in the first direction Y, each pair of second auxiliary pressing plates 521 is arranged on both sides of the bag opening of the handbag 10 in the conveying channel in the second direction X; in the first direction Y, the interval between the two pairs of second auxiliary pressing plates 521 is matched with the width of the first side face 120, and in the vertical direction, the upper edge of the second auxiliary pressing plate 521 is flush with the predetermined bag opening crease 150 at the upper end of the first side face 120.

[0200] It should be noted that in order to enable the two pairs of pre-pressing cylinders 441 to clamp different bag-shaped handbags 10, the two pairs of pre-pressing cylinders 441 are also arranged in the slide rail 103 through the bracket, and the interval of the two pairs of pre-pressing cylinders 441 in the slide rail 103 is adjusted through the lead screw, so as to match the width of the first side face 120 of the handbag 10.

[0201] The auxiliary pressing assembly 520 is arranged on the rack 100 on the side of each second auxiliary pressing plate 521 away from the conveying channel, and the auxiliary pressing driving member 522 is drivingly connected to the corresponding second auxiliary pressing plate 521 and drives the second auxiliary pressing plate 521 to move in the second direction X.

[0202] In addition, the contact area of the second auxiliary pressing plate 521 with the bag opening hem 140 is smaller than the contact area of the first auxiliary pressing plate 431 with the bag opening hem 140.

[0203] The two pairs of second auxiliary pressing plates 521 can be tightly clamped on the first side face 120 under the driving of the first pressing driving member, and the contact area of the second auxiliary pressing plate 521 with the bag opening hem 140 is smaller than the contact area of the first auxiliary pressing plate 431 with the bag opening hem 140, which makes the area for spraying glue liquid avoid.

[0204] The working process of the fold hem glue spraying component 500 of the handbag 10 will be described below.

[0205] The pair of conveying belts 210 convey the drawstring bag 10 with the bag opening flaps completed by the bag opening flapping component 400 to the corresponding positions of the edge gluing component 500. The glue spraying driving member 530 drives the transmission belt 531 to move, and the glue spraying mounting base 511 moves along the slide rail 103 in the first direction Y. The glue spraying head 510 sprays glue on the bag opening flaps 140 of the outer wall of the first side face 120.

[0206] Further, in order to improve the stability and accuracy of glue spraying, the auxiliary pressing driving member 522 drives the second auxiliary pressing plate 521 to move in the second direction X before glue spraying. After the first side face 120 is pressed and adhered by the second auxiliary pressing plate 521, the glue spraying head 510 sprays glue on the bag opening flaps 140 of the outer wall of the first side face 120 pressed and adhered by the auxiliary pressing assembly 520. Finally, a glue strip extending in the first direction Y is formed on the inner surface of the bag opening flaps 140, and the glue spraying is completed.

[0207] Finally, the auxiliary pressing driving member 522 drives the second auxiliary pressing plate 521 to retreat, and the drawstring bag 10 is moved towards the bag opening flapping component 600 under the driving of the conveying component 200.

[0208] Of course, the specific structure of the edge gluing component 500 is not limited to the structure in the above embodiment. In another alternative embodiment, a pair of glue spraying heads 510 are located above the corresponding side of the bag opening in the vertical direction.

[0209] Further, the edge gluing component 500 further comprises a glue spraying base corresponding to the glue spraying head 510. The lower part of the glue spraying base is in sliding connection with the slide rail, and the glue spraying base is provided with an auxiliary glue spraying motor which can drive the glue spraying head 510 to move in the second direction X.

[0210] The auxiliary glue spraying motor drives the glue spraying head 510 to move in the second direction X above the corresponding bag opening flaps, and the glue spraying head 510 sprays glue on the bag opening flaps 140.

[0211] In this embodiment, since the glue spraying head 510 is located above the bag opening on the corresponding side in the vertical direction, the bag opening hem 140 does not need to be pressed tightly against the outer wall of the first side 120, and the bag opening hem will reset to be close to horizontal under the action of the elastic force. Of course, a guide table can be provided to guide the bag opening hem 140 to return to the horizontal position, and the glue spraying head 510 is moved above the bag opening hem 140 by the auxiliary glue spraying motor in linkage to spray glue on the bag opening hem 140. In order to more conveniently spray glue on the bag opening hem 140, the glue spraying base can also be provided on the slide rail 103, the glue spraying driving member 530 drives the transmission belt 531 to move, and the glue spraying mounting seat 511 moves in the first direction Y along the slide rail 103, thereby forming a glue strip extending in the first direction Y on the bag opening hem 140. This structure does not need an auxiliary pressing assembly 520, and the structure of the hem glue spraying component 500 is simpler and occupies less space. The specific structure of the hem glue spraying component 500 can be designed according to the actual situation and specific needs by those skilled in the art, and this embodiment does not make specific limitations.

[0212] The specific structure of the bag opening folding component 600 will be described below.

[0213] As shown in Figure 10 The bag opening folding component 600 also includes a folding mounting frame 601 and a folding pushing driving member 602 provided on the folding mounting frame 601. The output end of the folding pushing driving member 602 is transmissionally connected to a linkage belt 603 extending in the first direction Y. A pair of folding pushing plates 611 are spaced apart in the first direction Y on the linkage belt 603. The folding pushing driving member 602 drives the linkage belt 603 to move, and the linkage belt 603 drives the pair of folding pushing plates 611 to move towards or away from each other in the first direction Y.

[0214] In addition, each of the pair of folding pushing plates 611 includes a pair of insertion plates 612 spaced apart in the second direction X and a hook plate 613 provided between the pair of insertion plates 612. The pair of insertion plates 612 and the hook plate 613 extend vertically downward.

[0215] In another alternative embodiment, the pair of insertion plates 612 extend downward in the vertical direction, and the hook plate 613 extends obliquely in the vertical direction away from the pair of insertion plates 612, thereby increasing the spacing between the pair of insertion plates 612 and the hook plate 613. When the pair of insertion plates 612 are inserted into the bag opening, the hook plate 613 can avoid interference with the inner wall of the tote bag 10.

[0216] The lower part of the hook plate 613 of the pair of inner push plates 611 forms a hook part facing each other, and the outer side edges of the pair of insertion plates 612 correspond to the folding edges of the pair of first side faces 120 and second side faces 130 respectively. The inner folding mounting frame 601 is provided with a lower insertion driving element 614 opposite to the pair of insertion plates 612 and driving the pair of insertion plates 612 to move along the vertical direction.

[0217] Further, above the inner folding mounting frame 601 on the rack 100, an inner folding lifting driving element 604 is provided in transmission connection with the inner folding mounting frame 601.

[0218] In use, the inner push driving element 602 drives the linkage belt 603 to move and link the pair of inner push plates 611 to move along the first direction Y towards or away from each other, so that the hook plate 613 on the inner push plate 611 can push the bag opening folding edge 140 on the second side face 130 to bend through the hook part. The inner folding lifting driving element 604 can drive the pair of inner push plates 611 to move along the vertical direction, so that the hook plate 613 of the inner push plate 611 can better hook the bag opening folding edge 140 of the second side face 130 to bend.

[0219] The outer side edges of the pair of insertion plates 612 correspond to the folding edges of the pair of first side faces 120 and second side faces 130 respectively. The lower insertion driving element 614 drives the insertion plate 612 to move downward along the vertical direction, so that the bag opening folding edge 140 of the first side face 120 and the second side face 130 can be bent towards the bag opening.

[0220] Further, as shown in the embodiment, the auxiliary inner folding assembly 630 includes two pairs of auxiliary push plates 631 arranged on both sides of the bag opening of the tote bag 10 in the conveying channel. Figure 11

[0221] Further, the rack 100 is provided with an auxiliary push plate driving element 632 opposite to the two auxiliary push plates 631 on the same side, and the auxiliary push plate driving element 632 is in transmission connection with the two auxiliary push plates 631. The auxiliary push plate driving element 632 is arranged on the guard plate 102 of the rack 100.

[0222] The auxiliary inner folding assembly 630 further includes a mounting plate 635 arranged on both sides of the tote bag 10 in the conveying channel. The mounting plate 635 is arranged with two push plate lifting driving elements 636 corresponding to the two auxiliary push plates 631 and in transmission connection with the auxiliary push plates 631 along the first direction Y. The output end of the auxiliary push plate driving element 632 is provided with a transmission wheel 633, and the linkage rod 634 is arranged between the transmission wheel 633 and the mounting plate 635. One end of the linkage rod 634 is eccentrically hinged to the transmission wheel 633, and the other end is connected to the mounting plate 635.

[0223] ​The second pair of suction members 621 comprises a second pair of swing arms 622 and a second mounting bracket 623 arranged at the upper end of the second pair of swing arms 622, and the second mounting bracket 623 is arranged with a plurality of second suction nozzles 624 in the first direction Y.

[0224] The second opening assembly 620 further comprises a second base 625 arranged on the frame 100 below the conveying channel and below the handbag 10, the lower end of the second pair of swing arms 622 of the second pair of suction members 621 is connected to the second base 625 below the conveying channel, and the lower end of the second pair of swing arms 622 is arranged with the second transmission gears 626 engaged with each other.

[0225] The second base 625 is arranged with a second swing arm driving member 627 on one side in the second direction X, the second swing arm driving member 627 is in transmission connection with the second swing arm 622 on the one side in the second direction X, and drives the second pair of swing arms 622 to swing towards or away from each other around the lower end. Wherein, the output end of the first swing arm driving member 427 is arranged with an intermediate linkage wheel, the first connecting rod is eccentrically connected to the intermediate linkage wheel, and the other end of the first connecting rod is connected to the lower side of the first swing arm 422.

[0226] Of course, the specific structure of the bag opening folding assembly 600 is not limited to the structure in the above embodiment, and those skilled in the art can design according to the actual situation and specific needs, and this embodiment does not make specific limitation.

[0227] The working process of the bag opening folding assembly 600 on the handbag 10 will be described below.

[0228] The pair of conveying belts 210 convey the tumbler bag 10, which has completed the edge folding and glue spraying, to the corresponding positions of the pair of second suction members 621. The second swing arm driving member 627 drives the pair of second swing arms 622 to swing toward each other around the lower ends thereof, so that the plurality of second suction nozzles 624 on the second mounting bracket 623 are close to the first side surface 120 of the tumbler bag 10. At this time, the plurality of second suction nozzles 624 suck and adsorb the first side surface 120. Further, the second swing arm driving member 627 drives the pair of second swing arms 622 to swing away from each other around the lower ends thereof, so that the upper portions of the pair of side surfaces are opened by a preset angle (for example, forty-five degrees) under the action of the suction force of the plurality of second suction nozzles 624. At this time, the inner folding lifting driving member 604 drives the hook plates 613 of the pair of inner push plates 611 to move in the vertical direction to between the bag opening folding edges 140 of the pair of second side surfaces 130. The inner pushing driving member 602 drives the hook plates 613 of the pair of inner push plates 611 to move away from each other in the first direction Y from the outside of the second side surface 130, so as to push the bag opening folding edges 140 of the second side surface 130 to fold outward. In the process of folding outward, the bag opening folding edges 140 of the second side surface 130 pull the bag opening folding edges 140 of the first side surface 120, so that the bag opening of the first side surface 120 has a tendency to fold inward.

[0229] Then, the push plate lifting driving member 636 drives the auxiliary push plate 631 to push the outwardly folded bag opening folding edges 140 of the first side surface 120 upward in the vertical direction until the push plate is flush with the predetermined bag opening folding crease 150 in the height direction. The auxiliary push plate driving member 632 drives the transmission wheel 633 to rotate, and the connecting rod 634 drives the mounting plate 635 and the auxiliary push plate 631 to push the bag opening folding edges 140 of the first side surface 120 horizontally inward in the second direction X.

[0230] Subsequently, the inner pushing driving member 602 drives the hook plates 613 of the pair of inner push plates 611 to push the bag opening folding edges 140 of the second side surface 130 toward each other in the first direction Y from the outside of the second side surface 130, and the inner folding lifting driving member 604 drives the hook plates 613 of the pair of inner push plates 611 to push the bag opening folding edges 140 of the second side surface 130 upward in the vertical direction from below the bag opening folding edges 140 of the second side surface 130, so that the bag opening folding edges 140 of the second side surface 130 are folded horizontally inward above the bag opening folding edges 140 of the first side surface 120.

[0231] The downward insertion driving member 614 drives the pair of insertion plates 612 to push the bag opening folding edges 140 downward in the vertical direction, so that the bag opening folding edges 140 of the first side surface 120 and the second side surface 130 in the horizontal state are bent inward toward the bag opening, and the inward folding of the bag opening folding edges 140 is completed.

[0232] Finally, the downward insertion driving member 614 drives the insertion plate 612 to withdraw from the bag opening, and the tumbler bag 10 is moved toward the edge pressing member 700 under the driving of the conveying member 200.

[0233] The specific structure of the folding and clamping component 700 is described below.

[0234] like Figure 12 As shown, in one embodiment, the folding and pressing component 700 further includes a pressing drive component 730 disposed on the frame 100 and capable of moving a pair of main pressing plates 710 toward the first side 120.

[0235] Optionally, in another embodiment, the folding and pressing component 700 further includes an intermediate component 720 disposed between a pair of main pressing plates 710 and vertically movable above the opening of the tote bag 10 in the conveying channel. The intermediate component 720 is cuboid and forms an inwardly inclined guide surface at the part where the side wall and bottom wall of the intermediate component 720 meet in the second direction X. An intermediate lifting drive component 740 that links the intermediate component 720 is provided on the frame 100.

[0236] The pressing drive 730 drives the main pressure plate 710 to move along the second direction X, so as to push the corresponding first side 120 and the inwardly folded bag opening edge 140 toward the intermediate piece 720, which is driven by the intermediate lifting drive 740 to move vertically into the bag opening of the tote bag 10.

[0237] An intermediate component 720 is provided between a pair of main pressure plates 710. When the pressing drive component 730 drives the main pressure plate 710 to move along the second direction X, the intermediate component 720 is driven by the intermediate lifting drive component 740 to move vertically into the bag opening of the tote bag 10, thereby pressing the first side 120 and the inwardly folded bag opening edge 140 onto the side wall of the intermediate component 720, ensuring that the first side 120 and the inwardly folded bag opening edge 140 are smoothly bonded by adhesive strips, and avoiding misalignment between the first side 120 and the inwardly folded bag opening edge 140.

[0238] Of course, the specific structure of the folding and pressing component 700 is not limited to the structure in the above embodiment. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not make specific limitations in this regard.

[0239] The following explanation will focus on the working process of the folding and pressing component 700 of the tote bag 10.

[0240] A pair of conveyor belts 210 transport the tote bag 10, which has undergone inward folding of the bag opening by the bag opening folding component 600, to the corresponding position of the folding edge pressing component 700. The pressing drive component 730 drives the main pressure plate 710 to move along the second direction X, so that the first side 120 and the inward folded bag opening edge 140 fit together.

[0241] Further, before the pressing driving member 730 drives the main pressing plate 710 to move along the second direction X, the intermediate piece 720 arranged between the pair of main pressing plates 710 can be driven by the intermediate lifting driving member 740 to move along the vertical direction into the bag opening of the handbag 10, so that the pressing driving member 730 drives the main pressing plate 710 to move along the second direction X, and the first side surface 120 and the inwardly folded bag opening hem 140 are pressed on the side wall of the intermediate piece 720, ensuring that the first side surface 120 and the inwardly folded bag opening hem 140 are flatly bonded by the adhesive tape.

[0242] Finally, the pressing driving member 730 drives the main pressing plate 710 to withdraw, and the intermediate lifting driving member 740 drives the intermediate piece 720 to move along the vertical direction to withdraw from the bag opening, and the handbag 10 is driven by the conveying member 200 to move towards the outlet end of the conveying channel.

[0243] Optionally, in an embodiment, as shown in the figure, the bag opening hem device 20 further comprises a feeding table 800 arranged at the inlet end side of the conveying channel and a discharging table 900 arranged at the outlet end side of the conveying channel, and the feeding table 800 and the discharging table 900 both extend along the second direction X and convey the handbags 10 in the folded state. Figure 2

[0244] In the figure, the clamping jaw 310 of the pulling member 300 moves the handbags 10 on the feeding table 800 to the inlet end of the conveying channel one by one, and the conveying member 200 drives the handbags 10 to pass through the bag opening outer folding member 400, the hem adhesive spraying member 500, the bag opening inward folding member 600 and the hem pressing member 700 in sequence, and then the handbags 10 are discharged from the outlet end of the conveying channel to the discharging table 900.

[0245] The bag opening hem device 20 can conveniently convey the handbags 10 to the conveying member 200 and collect the handbags 10 with completed hem through the arrangement of the feeding table 800 and the discharging table 900, thereby reducing the labor intensity and improving the production efficiency.

[0246] It should be noted that the feeding table 800 and the discharging table 900 have similar structures, and the feeding table 800 is taken as an example for description.
