[0001] The invention relates to the technical field of Christmas tree processing, and more specifically, to a branch shaping and cutting device for Christmas tree processing. Background Art

[0002] A Christmas tree is an evergreen tree decorated with candles and ornaments. As one of the important elements of Christmas, the modern Christmas tree originated in Germany and gradually became popular around the world, becoming one of the most famous traditions in Christmas celebrations. Evergreen trees do not exist in all regions. In order to meet people's needs for Christmas, people usually use plastic and steel wire to make fake Christmas trees with decorative effects.

[0003] In the process of making decorative Christmas tree branches and leaves, it is first necessary to cut the sheet plastic into long strips of plastic by a roller with a turning tool, and then send the long strips of plastic to a roller with a smaller turning tool spacing to be cut into a needle shape, and finally wrap the cut plastic sheet around the wire to obtain Christmas tree branches. People can send the Christmas tree branches to a drawing machine to cut them into suitable lengths according to their needs.

[0021] A branch shaping and cutting device for processing Christmas trees, such as Figure 1-Figure 4As shown, it includes a frame 27, on which a raw material roller 1 and a wire roller 2 are rotatably connected, a plastic sheet is rolled up on the raw material roller 1, and a wire is rolled up on the wire roller 2; a moving mechanism is arranged on one side of the frame 27 close to the raw material roller 1 and the wire roller 2, and is used to transport the plastic sheet and the wire. The plastic sheet rolled up on the raw material roller 1 is cut into a needle shape on both sides by a turning tool in advance, and then transported by the moving mechanism, and the moving mechanism includes a moving roller group, which is rotatably connected to the frame 27, and the moving roller group is arranged on the side of the wire roller 2 away from the raw material roller 1, and the moving roller group is located at the wire roller 2. At the bottom, the movable roller group includes a bottom roller 3 and a pressure roller 4. A groove 5 is provided on the outer wall of the bottom roller 3. A protrusion 6 is provided on the outer side of the pressure roller 4. The protrusion 6 is slidably connected to the groove 5. The plastic sheet and the iron wire pass through between the groove 5 and the protrusion 6. The top of the plastic sheet is squeezed by the protrusion 6 and can be tightly attached to the inner wall of the groove 5 to form a V shape. The iron wire is arranged on the top of the plastic sheet and can fall into the depression of the plastic sheet, thereby facilitating the formation of Christmas tree branches. The protrusion 6 can be inserted into the groove 5, which can facilitate the stable transportation of the plastic sheet and the iron wire. The bottom roller 3 and the pressure roller 4 assist in the transportation of the plastic sheet during the rotation process.

[0022] Furthermore, the cutting device includes a rotating mechanism disposed on the frame 27, which can intermittently wrap the plastic sheet around the outside of the iron wire. The rotating mechanism includes a motor 7 and a clamping jaw 8. The frame 27 is fixedly connected to a mounting frame 9, and a through slot 10 is provided on the mounting frame 9. The motor 7 is fixedly connected to the frame 27. The output end of the motor 7 is fixedly connected to a gear 11, and a gear 2 12 is meshed with the gear 11. The gear 2 12 is rotatably connected to the mounting frame 9, and a connecting slot 13 that is in communication with the through slot 10 is provided at the center of the gear 2 12. The clamping jaw 8 is slidably connected to the gear 2 12 through a pneumatic part (not shown in the figure), and the clamping jaw 8 relies on compressed air as a power source. It is used to clamp the iron wire horizontally. When winding the plastic sheet and the iron wire, the clamping claw 8 can clamp one end of the iron wire and the plastic sheet, and then start the motor 7. The motor 7 can drive the gear 11 to rotate.

After the winding is completed, the clamping claw 8 can loosen the iron wire, so that the iron wire drives the plastic sheet to continue to move forward, and intermittent winding of the plastic sheet can be achieved.

[0023] In one embodiment, the cutting device includes a cutting mechanism, which is arranged on a side of the frame 27 away from the raw material roller 1 and the wire roller 2, and is used to cut the wound plastic sheet and wire. The cutting mechanism includes a cutter assembly and a positioning assembly for fixing the wound plastic sheet and wire. The cutter assembly is arranged at the end of the frame 27, and the positioning assembly is arranged at the front side of the cutter assembly. After the plastic sheet and the wire are wound to form Christmas tree branches, the branches can be fixed through the positioning assembly, and then cut through the cutter assembly to obtain branches of the required length.

[0024] The positioning assembly includes two mutually slidably connected positioning blocks 20, a positioning groove 21 is provided on one side of the positioning block 20 close to the plastic sheet, the two positioning blocks 20 are arranged on the upper and lower sides of the plastic sheet, the cross section of the positioning groove 21 is arc-shaped, the upper and lower sides of the frame 27 are fixedly connected with mounting plates 22, the mounting plates 22 are fixedly connected with two cylinders 23, the pistons of the two cylinders 23 are respectively fixedly connected with the upper and lower positioning blocks 20, when the required branch length is reached, the upper and lower cylinders 23 can be started, so that the cylinders 23 push the positioning blocks 20 to move, thereby clamping the wire, so that the cutter assembly can cut the wire, and the cutter assembly includes a blade 1 24 and a blade 2 2 5. The blade 1 24 fits with the side of the positioning block 20, and a connecting plate 26 is fixedly connected to the side wall of the positioning block 20. The blade 25 is fixedly connected to the connecting plate 26. The sides of the blade 1 24 and the blade 2 25 fit with each other. The blade 2 25 is connected to the connecting plate 26 by bolts. The connecting plate 26 can make the blade 2 25 and the blade 1 24 misaligned with each other. In the actual debugging process, the position of the blade 2 25 on the connecting plate 26 can be adjusted to ensure that the blade 1 24 and the blade 2 25 fit together. When cutting is required, only the cylinder 2 23 above the wire needs to be started to complete the cutting while positioning, without additional cutting power, saving production costs.

[0025] In one embodiment, a traction mechanism is provided between the rotating mechanism and the cutting mechanism for assisting in traction of the wound plastic sheet and wire. The traction mechanism includes two staggered clamping jaws 14. Connecting blocks 15 are fixedly connected on both sides of a frame 27. A slide groove 16 is provided on the side of the connecting block 15 close to the plastic sheet. A screw rod 17 is rotatably connected in the slide groove 16. A mounting block 18 is threadedly connected to the screw rod 17. The side wall of the mounting block 18 abuts against the inner wall of the slide groove 16. The two connecting blocks 15 are staggered. The clamping jaws 14 are provided on the mounting block 18. A plurality of cylinders 19 are fixedly connected to the frame 27. The pistons of the plurality of cylinders 19 are respectively fixedly connected to the upper and lower clamping jaws 14. In the process of transporting the wound iron wire and plastic sheet forward, the power for the iron wire and plastic sheet to move forward comes from the iron wire roller 2 and the raw material roller 1. In case of insufficient power, the traction mechanism, that is, the two clamping jaws 14, can be started. During use, one of the clamping jaws 14 is first used to grasp the iron wire, and then the screw 17 is driven to rotate by the power source, so that the connecting block 15 can drive the clamping jaw 14 to move forward and transport the wound plastic sheet and iron wire forward. Then, the clamping jaw 14 is released to reverse the screw 17, thereby driving the clamping jaw 14 back to its original position. At this time, the other clamping jaw 14 is used to clamp the wound plastic sheet and iron wire. Repeating the above actions can enable the wound plastic sheet and iron wire to be continuously transported forward and maintain sufficient power. When not in use, the cylinder 19 can also be used to retract the clamping jaw 14 for standby use, thereby ensuring the continuous production of the device.

[0026] In addition, two conveying rollers 28 are rotatably connected between the mounting plate 22 and the mounting frame 9. An annular groove 29 is provided on the outer peripheral wall of the conveying roller 28. The conveying roller 28 is arranged between the mounting plate 22 and the mounting frame 9, and can provide support for the iron wire and the plastic sheet between the two, thereby reducing the possibility of deformation of the iron wire and the plastic sheet due to gravity, thereby improving the quality of the product. The wound iron wire and the plastic sheet are cylindrical and relatively soft. By providing the annular groove 29 on the two conveying rollers 28, the iron wire and the plastic sheet can pass through stably to prevent them from deformation.

[0027] The use of the present invention is as follows: When in use, first pre-install iron wire and cut plastic sheet on the raw material roller 1 and the iron wire roller 2 respectively, then put the plastic sheet at the bottom of the iron wire, make the two overlap and pass through the bottom roller 3 and the pressure roller 4, so that the plastic sheet wraps the iron wire and comes to the clamping claw 8, the clamping claw 8 clamps the iron wire and the plastic sheet, and then starts the motor 7, which can drive the gear 11 and the gear 2 12 to rotate, so that the plastic sheet is wrapped around the outside of the iron wire. After the winding is completed, the clamp 1 8 is released, allowing the wound iron wire and plastic sheet to continue to move forward. During the forward process, one of the clamps 14 is first used to grasp the iron wire, and then the screw 17 is driven to rotate by the power source, so that the connecting block 15 can drive the clamp 2 14 to move forward and transport the wound plastic sheet and iron wire forward. Then, the clamp 2 14 is released to reverse the screw 17, thereby driving the clamp 2 14 back to its original position. At this time, the other clamp 2 14 is used to clamp the wound plastic sheet and iron wire. Repeating the above actions can enable the wound plastic sheet and iron wire to be continuously transported forward and maintain sufficient power. Finally, the cylinder 2 23 drives the blade 1 24 and the blade 2 25 to move toward each other, and the wound iron wire and plastic sheet are cut according to demand, which can enable continuous production and save production time.
