Description

Technical Field

[0001] This invention relates to the field of paper rope bundling technology, and more specifically to a fully automatic paper rope bundling machine. Background Technology

[0002] Currently, plastic cable ties (mostly nylon) are commonly used to bind various children's toys, tools, appliances, kitchen and bathroom supplies, and handicrafts with cardboard packaging. Due to the environmentally unfriendly nature of nylon cable ties (difficult to degrade naturally), manufacturers are beginning to consider replacing existing plastic cable ties with kraft paper tape / rope containing adhesive. This paper tape / rope material is easily biodegradable and does not impact the environment, perfectly meeting environmental protection requirements. However, because the properties of paper tape / rope differ from nylon cable ties, its raw materials are generally produced in continuous long rolls, possibly 100 meters, 500 meters, or even longer. Currently, the... The plastic cable ties used are generally custom-made in various lengths, such as 5cm, 10cm, and 20cm. One end of the cable tie has a locking hole, which is inserted into the other end to secure it. The surface of the cable tie has continuous grooves, and the locking hole has a buckle. The cable tie binds the product tightly through the cooperation of the grooves and the buckle. This type of cable tie is currently widely used in various strapping machines on the market. However, for new materials such as kraft paper tape / paper strips / paper rope, this traditional strapping machine is obviously not suitable. Therefore, it is necessary to develop a special device for strapping products made of kraft paper tape / paper strips / paper rope. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fully automatic paper rope binding machine to solve the problems existing in the background art.

[0005] More specifically, the rope loading mechanism includes a first frame fixedly connected to the machine base, on which a carrier motor is mounted, and the output shaft of the carrier motor is driven to a paper rope carrier.

[0006] More specifically, the rope feeding mechanism includes a second frame fixedly connected to the machine base. A Z-axis lifting linear module is installed on the second frame. The Z-axis lifting linear module drives a lifting slide to move along the Z-axis direction. A rope feeding motor is installed on the lifting slide. The output shaft of the rope feeding motor is connected to a rope feeding drive wheel. A rope guide seat is provided on the outer side of the rope feeding drive wheel and is fixedly connected to the lifting slide. A guide channel for the rope to pass through from top to bottom is provided inside the rope guide seat. A rope feeding nozzle communicating with the guide channel is provided at the lower end of the rope guide seat. A rope guide wheel is installed at the upper end of the rope guide seat.

[0007] More specifically, the left and right rope pressing mechanisms include a left cylinder and a right cylinder installed at the bottom of the moving platform plate. The left and right cylinders respectively drive a pair of left and right pressing blocks to move along the X-axis. The moving platform plate is provided with a strip hole parallel to the X-axis. The upper end of the right pressing block is provided with a right pressing head located in the strip hole, and the upper end of the left pressing block is provided with a left pressing head located in the strip hole. The upper ends of the right and left pressing heads are both provided with chamfered bevels.

[0008] More specifically, the baffle mechanism includes a Y-axis cylinder mounted to the moving platform plate, the Y-axis cylinder driving a baffle to move along the Y-axis direction.

[0009] More specifically, the mobile platform mechanism includes a mobile platform plate slidably connected to the X-axis slide rail mounted on the machine base, a mobile platform motor mounted on one side of the mobile platform plate, an output shaft of the mobile platform motor connected to a drive wheel, the drive wheel connected to a driven wheel via a belt, the driven wheel mounted on the machine base, and the mobile platform plate connected to the belt.

[0010] More specifically, the ultrasonic welding mechanism includes an ultrasonic support fixedly connected to the machine base, on which a Z-axis cylinder is mounted, and the Z-axis cylinder drives a vertically upward ultrasonic welding head.

[0011] More specifically, a pressing mechanism is also installed on one side of the rope outlet. The pressing mechanism includes a pressing cylinder installed on the second frame, which drives a pressing head to move along the Z-axis.

[0012] A method for binding rope holes in a fully automatic strapping machine, characterized by comprising the following steps:

[0013] 1) Manually place the packaging card and product onto the moving platform. The packaging card has a left side hole and a right side hole on both sides of the product.

[0014] 2) The controller controls the Z-axis lifting linear module to move. The lifting slide moves downward along the Z-axis, causing the rope outlet to descend and insert into the left hole, and then feeds out a certain length of paper rope downward.

[0015] 3). Subsequently, the controller controls the left cylinder to work, and the left cylinder drives the left pressure block to move to the right, bending the paper rope and pressing down one end of the paper rope. At this time, the baffle mechanism is extended, cooperating with the left pressure block to press down the paper rope.

[0016] 4). Then the lifting slide moves upward along the Z-axis, the rope outlet is raised a certain distance, and at the same time the rope outlet motor drives the rope outlet wheel to move downward to send out a certain length of paper rope;

[0017] 5) The moving platform plate is driven to move to the left by the drive unit until the rope outlet is aligned with the right hole of the packaging card;

[0018] 6) Insert the rope nozzle below the right-side hole and touch the cutter below to cut the paper rope;

[0019] 7) The paper rope nozzle is raised, the right cylinder drives the right pressure block to bend the paper rope and press it down at the same time. The two ends of the paper rope overlap, and the pressing mechanism presses down synchronously to press the paper rope onto the upper surface of the product.

[0020] 8) The Z-axis cylinder of the ultrasonic welding mechanism drives the lifting to weld the overlapping parts of the paper rope to form a welded joint;

[0021] 9) The Y-axis cylinder of the baffle mechanism drives the baffle to retract;

[0022] 10). The packaging card and product are bundled together as a whole. The whole is then manually removed, and a new product and packaging card are placed in. This process is repeated from step 1) to step 10.

[0023] The beneficial effects of this invention are as follows: This equipment can automatically complete the bundling of products and paper cards using kraft paper rope. Manual operation is only required for placing and removing the products and paper cards; all other operations are automated. The bundling efficiency is high. After the product and packaging paper card are placed on the moving platform, the rope tip automatically aligns with the left and right holes on the packaging paper card during operation, performing rope feeding and cutting operations. Finally, ultrasonic welding is performed at the overlapping ends of the kraft paper rope. Because the kraft paper rope has adhesive on its surface, it firmly binds the product and paper card together. The equipment operation process is completely environmentally friendly and can completely replace the existing non-environmentally friendly plastic strapping machine operation process, making it highly versatile.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The fully automatic paper rope binding machine involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-7This invention provides an embodiment of a fully automatic paper rope bundling machine, including a machine base 1. A rope loading mechanism 2 is disposed above the machine base 1, on which a continuous kraft paper rope / paper strip is placed. A rope dispensing mechanism 3 is disposed adjacent to the rope loading mechanism 2. The rope dispensing mechanism 3 provides a driving force to feed / spit out the kraft paper rope / paper strip downwards from a rope dispensing nozzle 37, and enables the rope dispensing nozzle 37 to move up and down to insert into the target hole of a packaging card. A moving platform mechanism 4 is disposed below the rope dispensing mechanism 3. The moving platform mechanism 4 includes a moving platform plate 42 driven by a drive unit. The moving platform plate 42 is used to carry the product to be bundled and the packaging card, and can move along the X-axis to move the position of the product and the packaging card. Below the mobile platform plate 42 are a left rope pressing mechanism 51 and a right rope pressing mechanism 52, used to temporarily fix the ends of the kraft paper rope to the back of the card. Below the mobile platform mechanism 4, there is also a lower cutter 6 and an ultrasonic welding mechanism 7. The lower cutter 6 is used to cut the kraft paper rope, and the ultrasonic welding mechanism 7 is used to weld the two ends of the cut kraft paper rope together. On one side of the mobile platform plate 42, there is also a baffle mechanism 8, which acts as a pad during ultrasonic welding (when the ultrasonic welding head 73 presses the kraft paper rope upward, the baffle 82 extends above the kraft paper rope to support it). It also includes a controller 5, which is electrically connected to the above mechanisms and controls the operation of each mechanism according to a preset program.

[0036] The rope loading mechanism 2 includes a first frame 21 fixedly connected to the machine base 1. A carrier motor 22 is mounted on the first frame 21. The output shaft of the carrier motor 22 is connected to a paper rope carrier 23. Kraft paper rope rolls are loaded on the paper rope carrier 23. As the kraft paper rope is continuously consumed, the carrier motor 22 drives the paper rope carrier 23 to rotate and continuously unload the rope.

[0037] The rope feeding mechanism 3 includes a second frame 31 fixedly connected to the machine base 1. A Z-axis lifting linear module 32 is mounted on the second frame 31. The Z-axis lifting linear module 32 drives a lifting slide 33 to move along the Z-axis. A rope feeding motor 34 is mounted on the lifting slide 33. The output shaft of the rope feeding motor 34 is connected to a rope feeding drive wheel 35. A rope guide seat 36 fixedly connected to the lifting slide 33 is provided on the outer side of the rope feeding drive wheel 35. A guide channel 361 for the rope to pass through from top to bottom is provided inside the rope guide seat 36. A rope feeding nozzle 37 communicating with the guide channel 361 is provided at the lower end of the rope guide seat 36. A rope guide wheel 24 is mounted on the upper end of the rope guide seat 36. One end of the kraft paper rope enters the guide channel 361 of the rope guide seat 36 from the rope guide wheel 24 downwards. The kraft paper rope is fed out from the lower end of the rope outlet 37. A small section of the kraft paper rope inside the rope outlet 37 is in close contact with the rope outlet drive wheel 35. When the rope outlet motor drives the rope outlet drive wheel 35 to rotate, it will drive the kraft paper rope to move downward, thereby being fed out / spit out from the lower end of the rope outlet 37.

[0038] The left rope pressing mechanism 51 and the right rope pressing mechanism 52 include a left cylinder 511 and a right cylinder 521 installed at the bottom of the moving platform plate 42. The left cylinder 511 and the right cylinder 521 respectively drive a pair of left pressing blocks 512 and right pressing blocks 522 to move along the X-axis. The moving platform plate 42 is provided with a strip hole 420 parallel to the X-axis. The upper end of the right pressing block 522 is provided with a right pressing head 522' located in the strip hole. The upper end of the left pressing block 512 is provided with a left pressing head 512' located in the strip hole. The upper ends of the right pressing head 522' and the left pressing head 512' are both provided with chamfered bevels. First, one end of the kraft paper rope extends from the left hole 100A of the packaging card and is bent and pressed against the bottom of the baffle 82 by the moving left pressure block 512. Then, the other end of the kraft paper rope is bent and pressed against the right pressure block 522 to form an overlapping end 103 (the two ends of the kraft paper rope overlap). Finally, the overlapping end 103 is welded by the ultrasonic welding head 73.

[0039] The baffle mechanism 8 includes a Y-axis cylinder 81 mounted on the movable platform plate 42. The Y-axis cylinder 81 drives a baffle 82 to move along the Y-axis. After the paper card and product are placed on the movable platform plate 42, the Y-axis cylinder 81 drives the baffle 82 to extend, positioning it between the left hole 100A and the right hole 100B of the packaging paper card. After the product and packaging paper card are bundled together with kraft paper twine, the Y-axis cylinder 81 drives the baffle 82 to retract, making it easy to remove the bundled product.

[0040] The mobile platform mechanism 4 includes a sliding rail 41 parallel to the X-axis installed on the machine base 1. The mobile platform plate 42 is slidably connected to the X-axis sliding rail 41. A mobile platform motor 43 is installed on one side of the mobile platform plate 42. The output shaft of the mobile platform motor 43 is connected to a drive wheel 44. The drive wheel 44 is connected to a driven wheel 46 via a belt 45. The driven wheel 46 is installed on the machine base. The mobile platform plate 42 is connected to the belt 45. When the mobile platform motor 43 is working, it will drive the mobile platform plate 42 to move back and forth in the X direction via the belt 45. This facilitates the alignment of the left hole 100A and the right hole 100B of the packaging paper card 100 with the rope outlet 37, so that the kraft paper rope at the lower end of the rope outlet 37 can enter downward from the left hole or the right hole of the packaging paper card.

[0041] The ultrasonic welding mechanism 7 includes an ultrasonic support 71 fixedly connected to the machine base 1. A Z-axis cylinder 72 is mounted on the ultrasonic support 71, and the Z-axis cylinder 72 drives a vertically upward ultrasonic welding head 73. When the two ends of the kraft paper rope overlap to form an overlapping end 103, the ultrasonic welding head 73 presses against the overlapping end 103 to form a weld.

[0042] A pressing mechanism 9 is also installed on one side of the rope outlet 37. The pressing mechanism 9 includes a pressing cylinder 91 installed on the second frame. The pressing cylinder 91 drives a pressing head 92 to move along the Z-axis. When the pressing mechanism is working, the pressing head 91 presses against the kraft paper rope on the product, making it fit tightly. This facilitates a tight bond after bundling and prevents the product from becoming loose and falling off due to insufficient bundling.

[0043] A method for binding ropes and straps in a fully automatic strapping machine, the working process of which is as follows: Figures 8 to 10 As shown;

[0044] 1) First, manually place the packaging card 100 and the product 101 (in this example, a toy doll) on the moving platform plate 42. The packaging card 100 has a left hole 100A and a right hole 100B on both sides of the product 101 for the kraft paper rope to pass through.

[0045] 2) Controller 5 controls the Z-axis lifting linear module to move, the lifting slide moves downward along the Z-axis, so that the rope outlet descends and inserts into the left hole 101A and sends out a certain length of paper rope downward;

[0046] 3). Subsequently, controller 5 controls the left cylinder to work, the left cylinder drives the left pressure block to move to the right, bends the kraft paper rope and presses down one end of the kraft paper rope. At this time, the baffle mechanism is extended, and cooperates with the left pressure block to press down one end of the kraft paper rope.

[0047] 4). Then the lifting slide moves upward along the Z-axis, the rope outlet is raised a certain distance, and at the same time the rope outlet motor drives the rope outlet wheel to move downward to send out a certain length of paper rope;

[0048] 5) Move the platform plate to the left until the rope outlet is aligned with the right hole 100B of the packaging card;

[0049] 6) Insert the rope nozzle below the right-side hole and touch the cutter below to cut the paper rope;

[0050] 7) The paper rope nozzle rises, and the right cylinder drives the right pressure block to bend the paper rope and press it down simultaneously, causing the two ends of the paper rope to overlap to form an overlapping end (e.g., Figure 10 (At position 103 in the middle), the pressing mechanism presses down simultaneously, pressing the paper rope onto the upper surface of the product;

[0051] 8) The Z-axis cylinder of the ultrasonic welding mechanism drives the lifting to weld the overlapping parts of the paper rope to form a welded joint 103;

[0052] 9) The Y-axis cylinder of the baffle mechanism drives the baffle to retract;

[0053] 10). The paper card and the packaged product are bundled together as a whole. The whole is removed manually, and then a new product and packaging paper card are put in. The above steps 1) to 10) are repeated to realize the automated bundling function of the device.
