Description

Technical Field

[0001] This utility model relates to the field of paper rope bundling technology, and more specifically to a semi-automatic paper rope bundling machine. Background Technology

[0002] With increasing environmental awareness, people around the world are actively exploring effective ways to reduce plastic pollution. Against this backdrop, governments around the world have successively introduced various plastic bans to completely prohibit the production and sale of single-use plastic products in order to promote green and sustainable development.

[0003] Therefore, manufacturers are now using kraft paper rope with adhesive on the surface to bundle and package various products with cardboard signs. The bundling process usually involves pre-punching holes in the cardboard sign, placing the product between the two holes, and finally using kraft paper rope to wrap around the product and pass through the two holes to join them, thus completing the bundling and packaging of the product and cardboard sign. However, the above process is generally done manually, which results in a long bundling and packaging time and is not convenient.

[0004] Therefore, in order to solve the above problems, a semi-automatic paper rope bundling machine is needed. Utility Model Content

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model includes a binding assembly. First, the paper rope is inserted between the limit wheel and the drive wheel through the feeding channel on the outer plate. After the feeding sensor detects the insertion, the servo motor drives the drive wheel to rotate. The rotation of the drive wheel causes the paper rope to move. The paper rope enters the bottom rope channel through the lower guide groove of the channel plate, then passes through the bottom surface of the partition plate, and extends out from the guide channel through the guide plate. The end of the extended paper rope is passed through the left hole of the cardboard label. Then, the cardboard label is placed on the movable baffle, and then the product is placed on the cardboard label. The end of the paper rope is then passed through the right hole of the cardboard label and passed to the top of the partition plate. At this time, the partition plate connects the end of the paper rope with the bottom... The paper ropes are separated by a fourth cylinder, which then drives the pressure block to move upward and press the paper ropes together. The servo motor then drives the drive wheel to rotate in the opposite direction to tighten the paper ropes. The third cylinder drives the isolation plate to retract, allowing the upper and lower paper ropes to contact each other. The first cylinder then drives the lifting plate to move upward, which in turn drives the ultrasonic welding joint and the cutter to move upward. The ultrasonic welding joint performs ultrasonic welding on the overlapping part of the upper and lower paper ropes, and the cutter cuts the paper ropes. The second cylinder then drives the movable baffle to retract, so that the movable baffle no longer contacts the limit strip, thereby opening its channel and making it easy to remove the bundled products and cardboard labels. The above structure and method can achieve a convenient bundling effect for products and cardboard labels. Attached Figure Description

[0030] In this embodiment, the paper rope is first inserted into the feed channel on the outer plate 234 between the limiting wheel 241 and the drive wheel 236. After the feed sensor 242 senses the rope, the servo motor 235 drives the drive wheel 236 to rotate. The rotation of the drive wheel 236 drives the paper rope to move. The paper rope enters the bottom rope channel 233 through the lower guide groove of the upper channel plate 245, then passes through the bottom rope channel 233, passes through the bottom surface of the isolation plate 227, and extends out from the guide channel 204 through the guide plate 205. The end of the paper rope is then passed through the left hole of the cardboard label.

The end of the paper rope is then passed through the right hole of the cardboard label and passed above the isolation plate 227. At this time, the isolation plate 227 separates the end of the paper rope from the bottom rope body. The process begins with the fourth cylinder 230 driving the pressure block 232 upward to press the paper rope tightly. Then, the servo motor 235 drives the drive wheel 236 to rotate in the opposite direction to tighten the paper rope. The third cylinder 225 drives the isolation plate 227 to retract, causing the upper and lower paper ropes to contact each other. Then, the first cylinder 207 drives the lifting plate 209 to move upward. The lifting plate 209 simultaneously drives the ultrasonic welding joint 215 and the cutter 216 to move upward. The ultrasonic welding joint 215 performs ultrasonic welding on the overlapping part of the upper and lower paper ropes, and the cutter 216 cuts the paper ropes. Then, the second cylinder 218 drives the movable baffle 220 to retract, so that the movable baffle 220 no longer contacts the limiting strip 223, thereby opening its channel and making it convenient to remove the bundled products and cardboard labels. The above structure and method can achieve a convenient bundling effect for products and cardboard labels.

[0031] The working principle of this utility model is as follows: First, the paper rope is inserted into the feed channel on the outer plate 234 between the limit wheel 241 and the drive wheel 236. After the feed sensor 242 senses the paper rope, the servo motor 235 drives the drive wheel 236 to rotate. The rotation of the drive wheel 236 drives the paper rope to move. The paper rope enters the bottom rope channel 233 through the lower guide groove of the upper plate 245, then passes through the bottom rope channel 233, passes through the bottom surface of the partition plate 227, and extends out from the guide channel 204 through the guide plate 205. The end of the paper rope is then passed through the left hole of the cardboard label. The cardboard label is then placed on the movable baffle 220, and then the product is placed on the cardboard label. The end of the paper rope is then passed through the right hole of the cardboard label and passed to the top of the partition plate 227. At this time, the partition plate 227 connects the end of the paper rope with the bottom rope. The paper ropes are separated by a fourth cylinder 230, which drives the pressure block 232 to move upward and press it tightly. Then, the servo motor 235 drives the drive wheel 236 to rotate in the opposite direction and pull the paper ropes tight. The third cylinder 225 drives the isolation plate 227 to retract, so that the upper and lower paper ropes come into contact. Then, the first cylinder 207 drives the lifting plate 209 to move upward. The lifting plate 209 simultaneously drives the ultrasonic welding joint 215 and the cutter 216 to move upward. The ultrasonic welding joint 215 performs ultrasonic welding on the overlapping part of the upper and lower paper ropes. The cutter 216 cuts the paper ropes. Then, the second cylinder 218 drives the movable baffle 220 to retract, so that the movable baffle 220 no longer comes into contact with the limiting strip 223, thereby opening its channel and making it convenient to remove the bundled products and cardboard labels. The above structure and method can achieve a convenient bundling effect for products and cardboard labels.
