[0002] In modern production processes, various films, tapes, and papers are typically stored and transported using core tubes, facilitating their storage and transportation. Core tubes are used to wind products such as films for storage or transport; however, during transportation, the ends of the product may deform or wear due to compression or friction. Therefore, end baffles are usually installed at both ends of the core tube for protection. When installing the baffles, mounting grooves need to be created at the ends of the core tube to facilitate installation.

[0003] However, most existing core tubes are grooved using a lathe, which is complicated, has low grooving efficiency, is not suitable for grooving larger tubes, has low applicability, and is costly. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4The plastic core tube grooving equipment of this embodiment includes a frame 1. A first lifting mechanism 4 is vertically arranged at the bottom of the frame 1. A top plate 5 is fixedly connected to the lifting platform of the first lifting mechanism 4. A rolling mechanism 6 is arranged at the top of the top plate 5 for rolling and grooving the core tube. A mounting frame 2 is arranged on the side of the frame 1. A support mechanism 7 is arranged at the top of the mounting frame 2 for supporting the core tube. A limiting mechanism 8 is arranged on the side of the top plate 5 facing the support mechanism 7 for limiting the core tube. The rolling mechanism 6 includes a motor 601. The motor 601 is horizontally fixedly connected to the top of the top plate 5. A friction wheel 604 is fixedly connected to the rotating shaft of the motor 601. A fixing frame 602 is fixedly connected to the top of the side of the top plate 5 facing the support mechanism 7. A second lifting mechanism 603 is vertically arranged at the top of the fixing frame 602. A rolling wheel 605 is rotatably connected to the lifting platform of the second lifting mechanism 603. The rolling wheel 605 is located on top of the friction wheel 604. Before grooving, the height of the rolling mechanism 6 is adjusted according to the diameter of the core tube. During adjustment, the first lifting mechanism 4 drives the top plate 5 and the rolling mechanism 6 to move accordingly until the height of the friction wheel 604 matches the diameter of the core tube. Then, the end of the core tube to be grooved is fitted onto the outside of the friction wheel 604, so that the friction wheel 604 contacts the top of the inner wall of the core tube, while keeping the part of the core tube to be grooved directly below the rolling wheel 605. At this time, the other end of the core tube is supported by the support mechanism 7 to keep the core tube in a horizontal state. Then, the limiting mechanism 8 adjusts the tube in the vertical direction. The material is limited; during grooving, the second lifting mechanism 603 drives the rolling roller 605 to move downward until it abuts against the outer wall of the core tube. At this time, the motor 601 drives the friction wheel 604 to start rotating. When the friction wheel 604 rotates, it drives the core tube to start rotating under the action of friction. Then the second lifting mechanism 603 drives the rolling roller 605 to move downward a second time, generating pressure on the outer wall of the core tube. During the rotation of the core tube, the core tube is grooved by rolling. The grooving stops when the distance of the second movement of the second lifting mechanism 603 matches the depth of the grooving, thus achieving efficient grooving of the core tube.

[0022] The support mechanism 7 includes an outer cylinder 701, which is vertically fixed to the top of the mounting frame 2. A threaded sleeve 702 is rotatably connected to the top of the outer cylinder 701. A lead screw 703 is slidably connected to the inside of the outer cylinder 701 through a sliding sleeve. The threaded sleeve 702 is threadedly connected to the lead screw 703. A pair of handles are fixedly connected to the outer side wall of the threaded sleeve 702. An adjusting rod 704 is fixedly connected to the top of the lead screw 703. A pair of sliders 705 are symmetrically slidably connected to both sides of the adjusting rod 704. Several limiting holes are horizontally opened on the side of the adjusting rod 704. A locking pin is detachably connected between the sliders 705 and the limiting holes. A pair of adjusting wheels 706 are symmetrically rotatably connected to the top of the pair of sliders 705. When supporting the core tube, firstly, adjust the distance between a pair of adjusting wheels 706 according to the diameter of the core tube. During adjustment, slide a pair of sliders 705 towards each other, so that the pair of adjusting wheels 706 move towards each other until the adjusting wheels 706 support the core tube, causing it to disengage from the adjusting rod 704, thereby limiting the core tube in the horizontal direction. Then, rotate the threaded sleeve 702, causing the threaded screw 703 connected to it to move upward. When the screw 703 moves upward, it drives the adjusting rod 704 and the end of the core tube away from the rolling mechanism 6 to move upward until the core tube is in a horizontal state and stops, thus achieving the support of the core tube.

[0023] The limiting mechanism 8 includes a limiting frame 801, which is fixedly connected to the top of the top plate 5 on the side facing the support mechanism 7. A limiting cylinder 802 is vertically installed on the top of the limiting frame 801. The piston rod of the limiting cylinder 802 is fixedly connected to a limiting block 803. The bottom of the limiting block 803 is shaped like an inverted "V". Several rollers 804 are symmetrically rotatably connected to the bottom of the limiting block 803. When limiting, the limiting cylinder 802 drives the limiting block 803 to move downward to the limiting position. At this time, the rollers 804 at the bottom of the limiting block 803 contact the top of the core tube and exert downward pressure on the core tube, thereby limiting the core tube and preventing it from deflecting during grooving, which would affect the grooving effect.

[0024] A telescopic rod 3 is fixedly connected between the outer cylinder 701 and the side wall of the frame 1. The distance between the rolling mechanism 6 and the support mechanism 7 can be adjusted by the telescopic rod 3, thereby realizing the grooving of core tubes of different lengths.

[0025] The axes of the telescopic rod 3, roller 804, adjusting wheel 706 and rolling wheel 605 are all set parallel to the axis of friction wheel 604.

[0026] Working principle: Before grooving, the height of the rolling mechanism 6 is adjusted according to the diameter of the core tube. During adjustment, the first lifting mechanism 4 drives the top plate 5 and the rolling mechanism 6 to move accordingly until the height of the friction wheel 604 matches the diameter of the core tube. Then, the end of the core tube to be grooved is fitted onto the outside of the friction wheel 604, so that the friction wheel 604 contacts the top of the inner wall of the core tube, while keeping the part of the core tube to be grooved directly below the rolling wheel 605. Then, the other end of the core tube is supported by the support mechanism 7. During support, the distance between a pair of adjusting wheels 706 is adjusted according to the diameter of the core tube. During adjustment, a pair of sliders 705 slide in opposite directions, so that the pair of adjusting wheels 706 move in opposite directions until the height of the friction wheel 604 matches the diameter of the core tube. The roller 706 lifts the core tube, disengaging it from the adjusting rod 704, thus limiting the core tube in the horizontal direction. Then, the threaded sleeve 702 is rotated, causing the threaded screw 703 connected to it to move upward. As the screw 703 moves upward, it drives the adjusting rod 704 and the end of the core tube away from the rolling mechanism 6 to move upward until the core tube is in a horizontal state, thus supporting the core tube. Then, the limiting mechanism 8 limits the tube in the vertical direction. During the limiting, the limiting cylinder 802 drives the limiting block 803 to move downward to the limiting position. At this time, the roller 804 at the bottom of the limiting block 803 contacts the top of the core tube and exerts downward pressure on the core tube, thus limiting the core tube.

[0027] During grooving, the second lifting mechanism 603 drives the rolling roller 605 downward until it abuts against the outer wall of the core tube. At this time, the motor 601 drives the friction wheel 604 to start rotating. When the friction wheel 604 rotates, it drives the core tube to start rotating under the action of friction. Then, the second lifting mechanism 603 drives the rolling roller 605 to move downward a second time, generating pressure on the outer wall of the core tube. During the rotation of the core tube, the core tube is grooved by rolling. The grooving stops when the distance of the second movement of the second lifting mechanism 603 matches the depth of the grooving, thus achieving efficient grooving of the core tube.
