Description

Technical Field

[0001] This utility model relates to the field of paper packaging bag processing technology, specifically an automated rope threading device for tote bags. Background Technology

[0002] Tote bags or tote boxes are common household and business items, widely used in holiday gift boxes, high-end goods or clothing customized packaging; they can also be used for exhibition information bags and derivative packaging of cultural and creative products.

[0003] During the processing of tote bags or tote boxes, U-shaped ropes need to be threaded onto the flat bag or box body, and the ropes are glued to the bag or box body. Then, the bag or tote box is folded in half and glued again to form a tote bag or tote box.

[0004] The following technical defects are commonly found in the traditional assembly process of U-shaped drawstrings for tote bags or boxes:

[0005] (1) Manual rope threading is inefficient, with low daily output per person and generally large tolerance for rope length.

[0006] (2) The amount of glue applied manually was uneven. Sampling tests showed that the bonding strength was insufficient, resulting in a high rate of rope and strap detachment.

[0007] (3) The positioning accuracy of the rope is difficult to guarantee. The length of the rope is not uniform during manual operation, resulting in inconsistent left and right heights after the two ropes are glued together.

[0008] (4) Existing semi-automatic equipment uses a multi-link adjustment mechanism. When changing product specifications, multiple positioning modules need to be adjusted simultaneously, which takes a long time to debug. Furthermore, during operation, faults such as belt jamming and misalignment of adhesive bonding are prone to occur, resulting in low overall equipment efficiency.

[0009] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0010] This utility model addresses the above-mentioned technical problems by providing an automated rope threading device for tote bags. It fully automates manual operation, with the entire process of rope conveying, cutting, positioning, threading, and gluing being automated. This results in high production efficiency, reduced product costs, and significantly improved durability and length consistency of the ropes on tote bags, thereby enhancing product quality.

[0011] To achieve the above objectives, the technical solution of this utility model is as follows:

[0012] An automated drawstring threading device for tote bags includes a frame, on which a drawstring conveying mechanism, a U-shaped drawstring forming mechanism, and a drawstring threading mechanism are provided. The drawstring conveying mechanism pulls open a rolled-up drawstring and places the head end horizontally. The U-shaped drawstring forming mechanism clamps and fixes the head end of the drawstring, pulls the drawstring down into a U-shape to a set length, and then cuts it. The drawstring threading mechanism clamps both ends of the U-shaped drawstring and conveys it to the bottom of the flat bag body, so that the two ends of the U-shaped drawstring are aligned and pass through the two drawstring holes of the flat bag body.

[0013] The aforementioned automated drawstring threading device for tote bags is used to thread drawstrings onto flat bags. Four drawstring holes are pre-drilled on the flat bag, and two groups of U-shaped drawstrings are threaded through each hole. The drawstrings can be circular or flat. The drawstring threading mechanism clamps the protruding section of the U-shaped drawstring at both ends; this section has a set length and will pass through the drawstring holes.

[0014] This automated drawstring threading device for tote bags uses a drawstring conveying mechanism, a U-shaped drawstring forming mechanism, and a drawstring threading mechanism to automate the conveying, cutting, and positioning of the drawstrings to the threading holes. This results in high production efficiency, reduced product costs, and significantly improved consistency in drawstring length for tote bag products, thus enhancing product quality.

[0015] In a further optimized design, the frame is also equipped with a rotating rope-retrieving mechanism. This mechanism clamps both ends of the U-shaped rope. After the U-shaped rope is cut, it rotates both ends 90° in opposite directions so that the length extension direction of both ends of the U-shaped rope is consistent with the extension direction of the rope-threading hole in the flat bag. The rotating rope-retrieving mechanism then transfers the rotated U-shaped rope to the rope-threading mechanism, which clamps both ends of the U-shaped rope.

[0016] This rotating rope-taking mechanism is used for threading flat ropes, requiring that the length extension directions of both ends of the flat rope be aligned with the extension direction of the rope-threading holes in the rectangular shape of the flat bag.

[0017] In a further optimized design, the frame is also equipped with a bag conveying mechanism. The bag conveying mechanism transports the flat bag from the previous station to the rope threading station. During the rope threading process of the second set of rope holes of the flat bag, the bag conveying mechanism returns to continue transporting the next flat bag and pushes the flat bag with the rope threaded to the next station, and the process is repeated in a round-trip cycle.

[0018] The bag conveying mechanism operates continuously without waiting time during the conveying of flat bags. It can not only transport flat bags from the previous station to the rope threading station, but also push flat bags with ropes threaded to the next station at the same time, and carry them back and forth in a cyclical manner, thereby improving the efficiency of bag conveying.

[0019] In a further optimized solution, the rope threading station is equipped with a glue spraying and pressing mechanism. The glue spraying and pressing mechanism fixes the flat bag body of the rope threading station, then sprays glue onto the pressing part of the flat bag body and the rope, and then pushes the rope that has passed through the rope hole to the pressing part of the flat bag body and presses the two together.

[0020] The glue spraying and pressing mechanism features smooth and rapid glue spraying, rope pushing, and pressing and fixing actions, resulting in high production efficiency. The amount of glue sprayed is controllable, and the rope and flat bag body are pressed together in time after the glue is sprayed at the pressing part to ensure the bonding effect and strength of the two, significantly improving the durability of the ropes of the tote bag products.

[0021] In a further optimized design, the rope threading mechanism includes a rope clamping assembly, a blade insertion assembly, a left-right moving assembly, and a front-back moving assembly.

[0022] The clamping rope assembly and the inserting knife assembly are respectively disposed on the left and right moving assembly, and the left and right moving assembly is disposed on the front and back moving assembly;

[0023] The clamping rope assembly consists of two sets, which clamp the two ends of the U-shaped rope respectively;

[0024] The left and right moving components simultaneously move the two sets of clamping rope assemblies closer or further apart, so that the distance between the two ends of the U-shaped rope is consistent with the distance between the two rope holes of the flat bag body.

[0025] The forward and backward moving assembly delivers the U-shaped rope to the area directly below the flat bag body;

[0026] The inserter assembly consists of two sets, which are respectively connected to the clamping rope assembly. The two ends of the U-shaped rope are inserted and pass through the two rope holes of the flat bag body.

[0027] In a further optimized version, the clamping rope assembly includes a clamping seat and a rope threading clamping cylinder, wherein the clamping seat is connected to the piston rod end of the rope threading clamping cylinder;

[0028] The inserting knife assembly and the rope threading clamping cylinder are arranged side by side. The rope threading clamping cylinder moves back and forth to bring the clamping seat closer to or away from the side of the inserting knife assembly. The clamping seat clamps or releases one end of the U-shaped rope with the side of the inserting knife assembly.

[0029] In a further optimized design, the inserter assembly includes an inserter blade, an inserter guide seat, and an inserter moving assembly, wherein the inserter guide seat is provided with a vertical inserter moving hole;

[0030] The insert blade is located inside the insert blade moving hole, and the insert blade moving assembly drives the insert blade to move up and down inside the insert blade moving hole;

[0031] The inserter guide seat and the clamping seat clamp or release one end of the U-shaped rope;

[0032] As the forward and backward moving assembly transports the U-shaped rope to below the flat bag body, the portion of the U-shaped rope end exposed by the clamping seat is pushed to cover the insert knife moving hole; when the two ends of the U-shaped rope move to align with the two rope holes of the flat bag body, the insert knife moves upward to push the rope covering the insert knife moving hole and pass through the rope hole.

[0033] In a further optimized design, the left and right moving components include a left drive motor, a left synchronous belt and pulley assembly, a right drive motor, a right synchronous belt and pulley assembly, and left and right guide rail assemblies.

[0034] The two sets of clamping rope assemblies are respectively fixedly connected to the timing belts of the left timing belt and the right timing belt assembly, and the two sets of clamping rope assemblies are also respectively fixedly connected to the sliders of the left and right guide rail assemblies.

[0035] The left drive motor drives the left synchronous belt pulley assembly to rotate, while the right drive motor drives the right synchronous belt pulley assembly to rotate. The two sets of clamping rope assemblies move closer or further away from each other along the guide rails of the left and right guide rail assemblies.

[0036] The further optimized solution includes a front-to-back movement component comprising a front-to-back movement drive motor, a front-to-back movement synchronous belt and synchronous pulley assembly, and two sets of front-to-back movement guide rail assemblies.

[0037] The front and rear moving synchronous belt and synchronous pulley assembly is arranged horizontally front and rear. The two sets of front and rear moving guide rail assemblies are respectively arranged horizontally on both sides of the front and rear moving synchronous belt and synchronous pulley assembly. The left and right moving components are respectively connected to the sliders of the two sets of front and rear moving guide rail assemblies. The sliders of the two sets of front and rear moving guide rail assemblies are fixedly connected to the synchronous belt on one side of the front and rear moving synchronous belt and synchronous pulley assembly.

[0038] The forward and backward movement drive motor drives the forward and backward movement synchronous belt and synchronous wheel assembly to rotate in both directions, thereby driving the left and right movement assembly to move back and forth along the forward and backward movement guide rail assembly.

[0039] In a further optimized design, the bag conveying mechanism includes a bag clamping assembly and a bag conveying moving assembly; the bag clamping assembly clamps one side of the bag and is mounted on the bag conveying moving assembly; the bag conveying moving assembly drives the bag clamping assembly to move back and forth.

[0040] In a further optimized design, the bag clamping assembly includes two bag clamping finger cylinders and a bag clamping cylinder that moves the bag up and down.

[0041] The clamping part of the clamping finger cylinder is provided with bites at the top and bottom to clamp the edge of the bag body;

[0042] The two clamping bag finger cylinders are respectively disposed at the piston rod end of the clamping bag body up and down moving cylinder, and the clamping bag body up and down moving cylinder drives the clamping bag finger cylinder to move up and down;

[0043] When the bag conveying mechanism returns to continue conveying the next flat bag, the clamping bag moving cylinder drives the two clamping bag finger cylinders to move down to avoid the flat bag at the rope threading station.

[0044] The solution is further optimized so that the glue spraying and pressing mechanism includes a hot glue gun assembly, a bag fixing assembly, and a rope pushing and pressing assembly;

[0045] The bag fixing component presses and positions the flat bag at the rope threading station.

[0046] The hot glue gun assembly sprays glue onto the flat bag body at the point where it is pressed against the drawstring;

[0047] The cord pushing and pressing assembly is located on the side of the cord hole on the flat bag body. After the cord threading mechanism passes the cord through the cord hole, the cord remains vertical. The cord threading mechanism retracts from the cord hole, and the cord pushing and pressing assembly pushes the cord to make it flat against the pressing part of the flat bag body. The cord pushing and pressing assembly presses down the cord to make the glue evenly disperse and press and fix it to the flat bag body.

[0048] In a further optimized design, the bag fixing assembly includes two clamping and positioning blocks and a clamping and moving cylinder; the two clamping and positioning blocks are respectively located on both sides of the rope pushing and pressing assembly, and are located at the piston rod end of the clamping and moving cylinder; the clamping and moving cylinder moves up and down to drive the two clamping and positioning blocks to clamp or loosen the flat bag body.

[0049] A further optimized solution includes a flattening block, a pushing cylinder, and a pressing cylinder in the rope and belt flattening and pressing assembly.

[0050] The pressing cylinder is vertically arranged, and the pushing cylinder is horizontally arranged; the flattening block is arranged at the piston rod end of the pressing cylinder, and the pressing cylinder is arranged at the piston rod end of the pushing cylinder;

[0051] The pushing cylinder drives the pressing cylinder and the flattening block to move back and forth, and the pressing cylinder drives the flattening block to move up and down;

[0052] The distance between the bottom surface of the flattening block and the flat bag body is slightly greater than the thickness of the rope. The flattening block is located on the side of the rope hole. After the rope passes through the rope hole, it is vertically located on the front side of the flattening block. The flattening block pushes the rope to make it flat against the pressing part of the flat bag body. The flattening block presses down on the rope to make the glue evenly disperse and press and fix it to the flat bag body.

[0053] Compared with the prior art, the automated drawstring threading device for tote bags of this utility model has the following technical advantages:

[0054] 1. Improved production efficiency and capacity. The conveying of flat bags and the conveying, cutting, positioning, threading and gluing of ropes are all automated. The entire production process is fully automated, replacing manual labor and reducing product production costs.

[0055] 2. The movements of each component in the equipment are smooth and continuous, optimizing the process connection and motion control logic, and the assembly time of a single rope is short;

[0056] 3. The adhesive strength between the rope and the flat bag body is high and stable, and the rope is not easy to fall off after bearing weight, which improves the durability of the rope; the rope length is consistent and the symmetry deviation of the rope on both sides is small, which improves the overall quality of the product.

[0057] 4. The equipment adopts a modular design, which allows for fast installation and commissioning and low maintenance costs. Attached Figure Description

[0093] Frame 700, flat bag body A, rope hole A1, pressing part A2, rope B, pressing rope B1. Detailed Implementation

[0094] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0095] like Figures 1 to 29 As shown, this utility model provides an embodiment of an automated rope threading device for tote bags, which is used to thread flat ropes onto a flat bag body.

[0096] like Figure 3 As shown, the flat bag body A has four rectangular drawstring holes A1 and four pressing parts A2. The four drawstring holes A1 are divided into two groups, and each group is for threading a drawstring. Figure 5 For the U-shaped rope B shown, apply glue to each pair of pressing points A2 first. Figure 5 The medium-pressure composite rope section B1 passes through the rope hole A1 and lies flat on the surface. Figure 3 The pressing part A2 is glued to the flat bag body A.

[0097] like Figure 1 and Figure 2 As shown, the automated drawstring threading device for tote bags in this embodiment includes a frame 700, on which a drawstring conveying mechanism 100, a U-shaped drawstring forming mechanism 200, and a drawstring threading mechanism 300 are provided; the drawstring conveying mechanism 100 pulls open the coiled drawstring B and places the head end horizontally (e.g., Figure 7 The U-shaped rope forming mechanism 200 clamps and fixes the end of the rope, pulling the rope down into a U-shape (e.g., Figure 4After reaching the set length, it is cut; the rope threading mechanism 300 clamps the two ends of the U-shaped rope B and conveys it to the bottom of the flat bag body A, so that the two ends of the U-shaped rope B are aligned and pass through the two rope holes A1 of the flat bag body A.

[0098] The aforementioned automated drawstring threading device for tote bags is used to thread drawstrings onto a flat bag body A. Four drawstring holes A1 are pre-drilled on the flat bag body A, and two groups of holes are used to thread a U-shaped drawstring on each hole. The drawstring threading mechanism 300 clamps the exposed portion of the drawstring at both ends of the U-shaped drawstring. This portion of the drawstring has a predetermined length, such as... Figure 5 The pressed rope strip B1 shown is passed through the rope hole A1.

[0099] This automated rope threading device for tote bags uses a rope conveying mechanism 100, a U-shaped rope forming mechanism 200, and a rope threading mechanism 300 to automatically transport, cut, and position the rope to the threading hole A1. This automated operation results in high production efficiency, reduced product costs, and significantly improved consistency in rope length for tote bag products, thus enhancing product quality.

[0100] like Figure 2 , Figure 6 and Figure 15 As shown, the frame 700 is also equipped with a rotating rope-picking mechanism 400. The rotating rope-picking mechanism 400 clamps both ends of the U-shaped rope. After the U-shaped rope is cut, it rotates both ends 90° in one direction and the other in the opposite direction, so that the length extension direction of both ends of the U-shaped rope is consistent with the extension direction of the rope hole A1 of the flat bag body A (e.g., Figure 3 and Figure 5 The rotating rope-taking mechanism 400 transfers the rotated U-shaped rope to the rope-threading mechanism 300, which clamps both ends of the U-shaped rope.

[0101] The rotating rope-taking mechanism 400 is used for threading flat ropes, and the length extension direction of both ends of the flat rope is required to be consistent with the extension direction of the rope-threading hole A1 of the rectangle of the flat bag body A.

[0102] like Figure 6 As shown, the rope conveying mechanism 100 includes a rope conveying drive assembly 110, several support shafts 120, a counterweight assembly 130, and a fixed rope assembly 140.

[0103] The rope conveyor drive assembly 110 is located above the frame 700 and drives the rope roll to rotate and convey the rope forward. The rope passes around several support shafts 120 and counterweight assembly 130. The counterweight assembly 130 pulls the rope down by its own weight.

[0104] The rope conveyor drive assembly 110 is a fixed-speed reduction motor that drives the rope roll to rotate, and another fixed-speed reduction motor drives an elastically clamped roller to rotate and pull the rope.

[0105] The fixed rope assembly 140 sets the head of the rope horizontally (e.g.) Figure 7 And press and fix it.

[0106] The counterweight component 130 pre-pulls down the rope, so subsequent actions do not need to wait for the supply of the rope. The length of this section of the rope is greater than the length that needs to be cut in the U-shaped rope forming mechanism 200, ensuring the supply of the rope for subsequent actions. Moreover, the force required to pull the rope is small, only needing to overcome the gravity of the counterweight, ensuring smooth and stable rope pulling action.

[0107] like Figure 6 As shown, the counterweight assembly 130 includes a counterweight wheel 131 and two vertical guide rods 132. The rope passes around the counterweight wheel 131, and the two vertical guide rods 132 are arranged vertically side by side. The counterweight wheel 131 moves up and down along the vertical guide rods 132.

[0108] like Figure 7 and Figure 8 As shown, the fixed rope assembly 140 includes a support plate 141 and a clamping block 142. The support plate 141 is horizontally arranged, the rope is horizontally arranged on the support plate 141, and the clamping block 142 is arranged above the support plate 141. The clamping block 142 can move up and down to clamp or loosen the rope.

[0109] like Figure 8 As shown, the clamping block 142 is located at the piston rod end of the clamping cylinder 143, and the clamping cylinder 143 drives the clamping block 142 to move up and down.

[0110] like Figure 9 and Figure 10 As shown, the U-shaped rope forming mechanism 200 includes a rope pulling assembly 210, a rope blocking rod 220, a rope hooking assembly 230, and a rope cutting assembly 240;

[0111] The pull rope assembly 210 moves forward from the starting point to clamp the head of the rope and then returns to the starting point and remains stationary.

[0112] The rope guide rod 220 is located at the lower part of the rope at the front end of the rope assembly 210;

[0113] The hook rope assembly 230 presses down on the upper part of the rope between the rope guide rod 220 and the pull rope assembly 210. The hook rope assembly 230 presses down on the rope and pulls it down to the set length and then stays in place.

[0114] The rope cutting assembly 240 moves downward to cut the rope between the rope guide rod 220 and the rope conveying mechanism 100, at the following position: Figure 11 The position shown is between the support plate 141 and the rope guide rod 220. After the rope is cut, a small section of rope end remains outside the support plate 141 (e.g., Figure 7 This facilitates the clamping of the rope assembly 210 next time.

[0115] The U-shaped rope forming mechanism features 200 consecutive actions of pulling, pressing down, moving, and cutting the rope, resulting in high production efficiency and ensuring consistent rope length.

[0116] like Figure 10 and Figure 12 As shown, the pull cord assembly 210 includes an upper clamping block 211, a lower clamping block 212, a pull cord pneumatic finger 213, and a pull cord moving cylinder 214;

[0117] The upper clamping block 211 and the lower clamping block 212 are respectively fixed to the pneumatic finger 213 of the pull rope. The upper clamping block 211 and the lower clamping block 212 move up and down respectively to clamp or release the head of the rope (e.g. Figure 7 );

[0118] The pneumatic finger 213 is located at the piston rod end of the rope-pulling cylinder 214, which drives the upper clamping block 211 and the lower clamping block 212 to move back and forth.

[0119] like Figure 10 and Figure 13 As shown, the hook rope assembly 230 includes a hook rope rod 231 and a hook rope drive assembly 232. The hook rope rod 231 presses down the rope and moves it downward. The hook rope drive assembly 232 is connected to the hook rope rod 231 and drives it to move up and down reciprocally.

[0120] like Figure 13 As shown, the hook rope assembly 230 is also equipped with a hook rod moving cylinder 233. The hook rope rod 231 is fixed to the piston rod end of the hook rod moving cylinder 233. The hook rod moving cylinder 233 drives the hook rope rod 231 to extend or retract.

[0121] like Figure 10 and Figure 13 As shown, the hook rope drive assembly 232 includes a hook rope servo motor 232a, a hook rope synchronous belt pulley assembly 232b, and an up-and-down moving guide rail assembly 232c. The up-and-down moving guide rail assembly 232c is vertically arranged. The hook rope rod 231 is fixedly connected to the synchronous belt on one side of the hook rope synchronous belt pulley assembly 232b. The hook rope rod 231 is also fixedly connected to the slider of the up-and-down moving guide rail assembly 232c. The hook rope servo motor 232a rotates forward and backward, driving the hook rope rod 231 to move up and down along the guide rail of the up-and-down moving guide rail assembly 232c.

[0122] like Figure 10 and Figure 14 As shown, the rope cutting assembly 240 includes a rope cutting moving cylinder 241 and a hot cutting blade 242. The hot cutting blade 242 is connected to the piston rod end of the rope cutting moving cylinder 241. The rope cutting moving cylinder 241 drives the hot cutting blade 242 to move up and down, thereby cutting the rope.

[0123] like Figure 6 and Figure 15 As shown, the rotating rope-taking mechanism 400 includes a rope-taking moving assembly 410, a rope-taking clamping assembly 420, and a rotating assembly 430.

The rope threading clamping cylinder 312 moves back and forth to bring the clamping seat 311 closer to or away from the side of the inserting knife assembly 320. The clamping seat 311 clamps or releases one end of the U-shaped rope with the side of the inserting knife assembly 320.

[0138] like Figure 22 and Figure 23 As shown, the inserter assembly 320 includes an inserter blade 321, an inserter guide seat 322, and an inserter moving assembly 323. The inserter guide seat 322 is provided with a vertical inserter moving hole 322a.

[0140] One end of the U-shaped rope is clamped or released between the insert guide seat 322 and the clamping seat 311;

[0141] During the process of the forward and backward moving assembly 340 conveying the U-shaped rope to the bottom of the flat bag body A, the part of the U-shaped rope end exposed by the clamping seat 311 is pushed to cover the insert knife moving hole 322a; when the two ends of the U-shaped rope move to align with the two rope holes A1 of the flat bag body A, the insert knife 321 moves up to push the rope covering the insert knife moving hole 322a up and through the rope hole A1.

[0142] like Figure 22 and Figure 23 As shown, the inserter assembly 320 also includes an inserter up-and-down movement cylinder 323a and an inserter seat 323b. The inserter blade 321 is fixed on the inserter seat 323b, and the inserter seat 323b is connected to the piston rod end of the inserter up-and-down movement cylinder 323a.

[0143] like Figure 20 As shown, the left and right moving assembly 330 includes a left drive motor 331, a left synchronous belt and synchronous pulley assembly 332, a right drive motor 333, a right synchronous belt and synchronous pulley assembly 334, and left and right guide rail assemblies 335.

[0144] Two sets of clamping rope assemblies 310 are respectively fixedly connected to the timing belts of the left timing belt timing pulley assembly 332 and the right timing belt timing pulley assembly 334. The two sets of clamping rope assemblies 310 are also respectively fixedly connected to the sliders of the left and right guide rail assemblies 335.

[0145] The left drive motor 331 drives the left synchronous belt pulley assembly 332 to rotate, while the right drive motor 333 drives the right synchronous belt pulley assembly 334 to rotate. The two sets of clamping rope assemblies 310 move closer or further away from each other along the guide rails of the left and right guide rail assemblies 335.

[0146] like Figure 21 As shown, the forward and backward moving assembly 340 includes a forward and backward moving drive motor 341, a forward and backward moving synchronous belt and synchronous pulley assembly 342, and two sets of forward and backward moving guide rail assemblies 343.

The sliders of the two sets of front and rear moving guide rail assemblies 343 are fixedly connected to the synchronous belt on one side of the front and rear moving synchronous belt and synchronous pulley assembly 342.

[0148] The forward and backward movement drive motor 341 drives the forward and backward movement synchronous belt and synchronous pulley assembly 342 to rotate in both directions, which in turn drives the left and right movement assembly 330 to move back and forth along the forward and backward movement guide rail assembly 343.

[0149] like Figure 1 As shown, the frame 700 is also equipped with a bag conveying mechanism 500. The bag conveying mechanism 500 conveys the flat bag A from the previous station to the rope threading station. During the rope threading process of the second set of rope threading holes A1 of the flat bag A, the bag conveying mechanism 500 returns to continue conveying the next flat bag A and pushes the flat bag A with the rope threaded to the next station, and conveys it back and forth in a cycle.

[0150] The bag conveying mechanism 500 operates continuously during the conveying of flat bag A without waiting time. It can not only convey flat bag A from the previous station to the rope threading station, but also push flat bag A with rope threaded to the next station at the same time, and carry it back and forth in a cycle, which improves the efficiency of bag conveying.

[0151] like Figure 1 , Figure 24 and Figure 25 As shown, the bag conveying mechanism 500 includes a bag clamping assembly 510 and a bag conveying moving assembly 520; the bag clamping assembly 510 clamps one side of the bag and is mounted on the bag conveying moving assembly 520; the bag conveying moving assembly 520 drives the bag clamping assembly 510 to move back and forth.

[0152] like Figures 25 to 27 As shown, the bag clamping assembly 510 includes two bag clamping finger cylinders 511 and a bag clamping up-and-down moving cylinder 512.

[0153] The clamping part of the clamping finger cylinder 511 is equipped with bites at the top and bottom to clamp the edge of the bag body;

[0154] Two clamping bag finger cylinders 511 are respectively installed at the piston rod end of the clamping bag body up and down moving cylinder 512. The clamping bag body up and down moving cylinder 512 drives the clamping bag body finger cylinder 511 to move up and down.

[0155] When the bag conveying mechanism 500 returns to continue conveying the next flat bag A, the clamping bag moving cylinder 512 drives the two clamping bag finger cylinders 511 to move down to avoid the flat bag A at the rope threading station.

[0156] like Figures 25 to 27 As shown, the bag conveying and moving assembly 520 includes a bag moving drive motor 521, a bag moving synchronous belt and synchronous wheel assembly 522, and two sets of bag moving guide rail assemblies 523.

[0157] The bag body moving synchronous belt synchronous wheel assembly 522 is set horizontally to the left and right. Two sets of bag body moving guide rail assemblies 523 are respectively set horizontally to the left and right on both sides of the bag body moving synchronous belt synchronous wheel assembly 522. The bag body clamping assembly 510 is connected to the slider of the two sets of bag body moving guide rail assemblies 523. The slider of the two sets of bag body moving guide rail assemblies 523 is fixedly connected to the synchronous belt on one side of the bag body moving synchronous belt synchronous wheel assembly 522.

[0158] The bag body moving drive motor 521 drives the bag body moving synchronous belt synchronous wheel assembly 522 to rotate forward and backward, driving the bag body clamping assembly 510 to move back and forth along the bag body moving guide rail assembly 523.

[0159] like Figure 2As shown, the rope threading station is equipped with a glue spraying and pressing mechanism 600. The glue spraying and pressing mechanism 600 fixes the flat bag body A of the rope threading station, then sprays glue onto the pressing part A2 of the flat bag body A and the rope, and then pushes the rope that has passed through the rope hole A1 to the pressing part A2 of the flat bag body A and presses the two together.

[0160] The glue spraying and pressing mechanism 600 has a smooth and fast action for spraying glue, pushing ropes and pressing and fixing, resulting in high production efficiency. The amount of glue sprayed is controllable. After the glue is sprayed on the pressing part A2, the rope and flat bag body A are pressed in time to ensure the bonding effect and strength of the two, which significantly improves the durability of the ropes of the tote bag products.

[0161] like Figure 2 and Figure 28 As shown, the glue spraying and pressing mechanism 600 includes a hot glue gun assembly 610, a bag fixing assembly 620, and a rope pushing and pressing assembly 630.

[0162] The bag fixing component 620 presses and positions the flat bag A at the rope threading station, keeping it stationary.

[0163] The hot glue gun assembly 610 sprays glue onto the flat bag body A and the pressing part A2 where it meets the drawstring;

[0164] The cord pushing and pressing assembly 630 is located on the side of the cord hole A1 of the flat bag body A. After the cord threading mechanism 300 passes the cord through the cord hole A1, the cord remains vertical. The cord threading mechanism 300 retracts from the cord hole A1, and the cord pushing and pressing assembly 630 pushes the cord to make it flat against the pressing part A2 of the flat bag body A. The cord pushing and pressing assembly 630 presses down the cord to make the glue evenly disperse and press and fix it to the flat bag body A.

[0165] like Figure 28 and Figure 29 As shown, the bag fixing assembly 620 includes two pressing and positioning blocks 621 and a pressing and moving cylinder 622; the two pressing and positioning blocks 621 are respectively arranged on both sides of the rope pushing and pressing assembly 630, and are located at the piston rod end of the pressing and moving cylinder 622; the pressing and moving cylinder 622 moves up and down to drive the two pressing and positioning blocks 621 to press or release the flat bag A.

[0166] like Figure 28 and Figure 29 As shown, the rope flattening and pressing assembly 630 includes a flattening block 631, a pushing cylinder 632, and a pressing cylinder 633;

[0167] The pressing cylinder 633 is set vertically, and the pushing cylinder 632 is set horizontally; the flattening block 631 is set at the piston rod end of the pressing cylinder 633, and the pressing cylinder 633 is set at the piston rod end of the pushing cylinder 632.

[0168] The push cylinder 632 drives the pressing cylinder 633 and the flattening block 631 to move back and forth, and the pressing cylinder 633 drives the flattening block 631 to move up and down;

[0169] The distance between the bottom surface of the flattening block 631 and the flat bag body A is slightly greater than the thickness of the rope. The flattening block 631 is located on the side of the rope hole A1. After the rope passes through the rope hole A1, it is vertically located on the front side of the flattening block 631. The flattening block 631 pushes the rope so that it covers the pressing part A2 of the flat bag body A. The flattening block 631 presses down on the rope so that the glue is evenly dispersed and pressed and fixed to the flat bag body A.

[0170] The operation process of the automated drawstring device for tote bags in this embodiment is as follows:

[0171] 1. For example Figure 6 As shown, a rope reel is installed on the rope conveyor drive assembly 110, and the rope is wound around several support shafts 120 and counterweight wheels 131. A section of the rope head is placed horizontally on the support plate 141, with a small section of the support plate 141 protruding (e.g., Figure 7 The pressing cylinder 143 moves down, causing the pressing block 142 to move down and press and fix the rope to the support plate 141.

[0172] 2. For example Figure 10 As shown, the cable-pulling cylinder 214 moves forward, and the cable-pulling pneumatic finger 213 clamps the cable.

[0173] 3. Move the clamping cylinder 143 upward to release the rope on the support plate 141;

[0174] 4. The moving cylinder 214 moves backward and returns, pulling out the rope;

[0175] 6. For example Figure 10 As shown, the hook rod moving cylinder 233 extends the hook rope rod 231 to be positioned above the pulled-out rope;

[0176] 7. For example Figure 10 As shown, the downward movement of the hook rope lever 231 causes the rope to move downward. One end of the rope is clamped by the pneumatic finger 213, and the other end is pressed against the rope-blocking lever 220, forming a U-shape (as shown). Figure 4 The hook rope and pole 231 move down to the set distance and stop moving;

[0177] 8. The clamping cylinder 143 moves down to clamp the rope on the support plate 141;

[0178] 9. The rotating rope-taking mechanism 400 moves and clamps both ends of the U-shaped rope;

[0179] 10. The moving cylinder 241 for cutting the rope moves downward, driving the hot cutting blade 242 to cut the rope;

[0180] 11. The hook rod moving cylinder 233 retracts the hook rope rod 231, and the hook rope rod 231 moves upward to the starting position;

[0181] 12. Rotate the rope-taking mechanism 400 degrees to rotate both ends of the U-shaped rope, so that the U-shaped rope is as... Figure 15 The shape shown;

[0182] 13. The rotating rope-taking mechanism 400 transfers the U-shaped rope to the rope-threading clamping cylinder 312 for clamping (e.g., Figure 20 );

[0183] 14. The forward and backward moving assembly 340 moves the U-shaped rope forward to the rope threading station. Since the rope clamping assembly 420 is located above the rope clamping assembly 310, the corresponding fixing clamp 421 is located above the clamping seat 311. During the movement of the forward and backward moving assembly 340, the exposed part of the rope is blocked by the fixing clamp 421, thus covering the inserting knife moving hole 322a (e.g., Figure 6 );

[0184] 15. The pressing cylinder 622 drives the pressing positioning block 621 to move down and fix the flat bag body A. The hot glue gun assembly 610 sprays glue onto the pressing part A2.

[0185] 16. The upward movement of the inserter cylinder 323a moves the inserter blade 321 upward, thereby moving the pressing rope belt B1 (e.g.) Figure 5 ) Pass through the rope hole A1;

[0186] 17. Insert blade 321 and move it downwards;

[0187] 18. Push cylinder 632 to drive push block 631 to push pressing rope B1 forward so that it covers pressing part A2 flat;

[0188] 19. The pressing cylinder 633 drives the flattening block 631 to move down, and the flattening block 631 presses down on the pressing rope B1 to make the glue evenly disperse and press and fix it to the flat bag body A.

[0189] 20. After assembling one U-shaped rope belt B, the bag conveying mechanism 500 moves the plane bag A so that the second set of rope holes A1 is located at the rope threading station, and the assembly of the second U-shaped rope belt is completed in sequence.

[0190] 21. When the bag conveying mechanism 500 moves the flat bag A to the second set of rope holes A1 at the rope threading station, the bag conveying mechanism 500 returns to continue conveying the next flat bag A; during the conveying of the next flat bag A, the previous flat bag A with rope threaded is pushed to the next station, and the conveying is carried out in a round trip cycle; thus realizing the automated rope threading of the flat bag A during the processing of the tote bag.

[0191] This utility model relates to an automated rope threading device for tote bags. It fully automates manual operation, with the entire process of rope conveying, cutting, positioning, threading, and gluing being automated. This results in high production efficiency, reduced product costs, and significantly improved durability and length consistency of the ropes on tote bags, thereby enhancing product quality.

[0192] By achieving the above objectives, this patented device can significantly improve the durability, aesthetics, and brand value of tote bag products, and is especially suitable for high-end gifts, luxury packaging, and other scenarios with stringent requirements for process precision. At the same time, it reduces the overall production costs of enterprises and promotes the development of the paper product processing industry towards intelligent automation and sustainability.
