Description
Technical Field
[0001] This application relates to the field of core tube processing equipment technology, and in particular to a forming device for the surface texture of core tubes. Background Technology
[0002] In the production process of core tubes, in order to improve the anti-slip effect when winding flexible materials such as film and paper, it is usually necessary to process a uniformly distributed rough texture on the outer circumference surface of the core tube.
[0003] Currently, rough textures on the surface of core tubes are mainly processed through sandblasting and mechanical engraving. Sandblasting creates rough textures by high-speed jetting of sand particles to impact the surface of the core tube. However, the distribution of sand particles is difficult to control during sandblasting, making it impossible to precisely control the texture shape. Mechanical engraving creates textures by directly cutting the surface of the core tube with a tool. However, the cutting depth is easily affected by tool wear, both of which have significant drawbacks.
[0004] Both of the above processing techniques suffer from poor texture uniformity in the surface texture processing of core tubes, failing to meet the production requirements for high-precision and high-consistency anti-slip textures.

[0038] Specifically, automatic texturing of the surface of the core tube body 400 can be achieved by rotating the two first forming templates 204 and the two second forming templates 208.

[0041] In this embodiment, by setting up a forming mechanism 200 and a traction mechanism 300, when the device processes the surface of the core tube with rough texture, the rotation of the third motor 303 drives one roller to rotate. The rotation of this roller, under the action of the two third toothed discs 304, drives the two traction rubber rollers 302 to rotate in opposite directions, realizing the automatic conveying of the core tube body 400.

In this way, the device can process a uniformly distributed rough texture on the surface of the core tube body 400 through the cooperation of the first forming templates 204 and the second forming templates 208, thereby improving the anti-slip effect of the core tube body 400 when winding film or paper.
[0042] Example 2 Based on Example 1, referring to Figures 5 to 9 And unlike Example 1, the following is true: Please refer to this carefully. Figure 6 , Figure 7The frame 100 is equipped with a cooling mechanism 600. The cooling mechanism 600 includes a water collection tank 6014 fixed at the bottom of the frame 100, and two rectangular boxes 601 fixed on the front and back of the frame 100 and corresponding to the first forming template 204. The frame 100 is also equipped with two fixing rings 602 fixed inside by connecting rods. The inner walls of the two fixing rings 602 are rotatably equipped with mesh rings 603. The inner walls of the mesh rings 603 are symmetrically equipped with two annular tubes 604. The two annular tubes 604 are connected by several connecting tubes. The core tube body 400 passes through the middle of the two annular tubes 604. The inner ring surface of the annular tubes 604 is arranged in a circumferential array with several water outlets 605.
[0043] Specifically, the rectangular box 601 can transport the cooling water in the water collection tank 6014 to the annular pipe 604, and spray it onto the surface of the core tube body 400 through the water outlet 605.
[0044] Please refer to this carefully. Figure 6 , Figure 7 The inner wall of the rectangular box 601 is slidably provided with a rectangular plate 606 and a sealing plate 607, and two symmetrical top rods 608 are fixed on the opposite surfaces of the rectangular plate 606 and the sealing plate 607.
[0045] Specifically, the sealing plate 607 can be moved automatically by the movement of the rectangular plate 606 and the action of the two push rods 608.
[0046] Please refer to this carefully. Figure 7 , Figure 8 The inner top wall of the rectangular box 601 is rotatably provided with a rotating rod 609 extending to the outer surface of the rectangular box 601. A small transmission wheel 6010 is fixed at the top of the rotating rod 609. A large transmission wheel 6011 is fixed on the surface of the first roller 203. A transmission belt 6012 is sleeved on the surfaces of the large transmission wheel 6011 and the small transmission wheel 6010. A first reciprocating threaded post 6013 is fixed on the outer surface of the bottom end of the rotating rod 609. A first threaded hole is opened on the surface of the rectangular plate 606, which is threadedly connected to the outer surface of the first reciprocating threaded post 6013.
[0047] Specifically, the rotation of the first roller 203 drives the large transmission wheel 6011 to rotate, and the rotation of the large transmission wheel 6011 drives the small transmission wheel 6010 to rotate through the transmission belt 6012. Thus, the rotation of the first roller 203 drives the rotating rod 609 to rotate automatically, and the rotation of the rotating rod 609 drives the first reciprocating threaded column 6013 to rotate. The rotation of the first reciprocating threaded column 6013 causes the rectangular plate 606 to move back and forth automatically.
[0048] Please refer to this carefully. Figure 7 , Figure 8The front and back of the water collection tank 6014 are equipped with heat exchange coolers 6015. The water inlet end of the heat exchange cooler 6015 extends to the inner bottom of the water collection tank 6014. The outer surface of the rectangular box 601 is respectively equipped with a water suction pipe 6016 and a water outlet pipe 6017. One end of the water suction pipe 6016 and the water outlet pipe 6017 both extend to the inner bottom of the rectangular box 601. The other end of the water suction pipe 6016 is connected to the water outlet end of the heat exchange cooler 6015. The other end of the water outlet pipe 6017 is connected to two annular pipes 604. The surfaces of the water suction pipe 6016 and the water outlet pipe 6017 are respectively equipped with a water suction check valve and a water outlet check valve.
[0049] Specifically, when the sealing plate 607 moves upward, the water in the water collection tank 6014 can be cooled by the heat exchanger 6015 through the water suction pipe 6016 and then sucked into the rectangular box 601. When the sealing plate 607 moves downward, the cooling water can be transported to the annular pipe 604 through the water outlet pipe 6017 and sprayed onto the surface of the core tube body 400 through the water outlet head 605, thereby achieving automatic cooling of the core tube body 400 after the rough texture has been processed.
[0050] In this invention, by setting a cooling mechanism 600, when the rotation of the first motor 206 drives the two first forming templates 204 to rotate in opposite directions to process the texture on the surface of the core tube body 400, the rotation of the first roller 203 can drive the large transmission wheel 6011 to rotate. The rotation of the large transmission wheel 6011 drives the small transmission wheel 6010 and the rotating rod 609 to rotate faster via the transmission belt 6012. The rotation of the rotating rod 609 drives the first reciprocating threaded column 6013 to rotate, and the rotation of the first reciprocating threaded column 6013 drives the rectangular plate 606 to move up and down reciprocally. The reciprocating movement of the rectangular plate 606 can drive the sealing plate 607 to move up and down through the top rod 608. When the sealing plate 607 moves upward, it can draw water from the water collection tank 6014 through the water suction pipe 6016, cool it through the heat exchange cooler 6015, and then draw it into the rectangular box 601. When the sealing plate 607 moves downward, it can deliver cooling water to the annular pipe 604 through the water outlet pipe 6017, and spray it onto the surface of the core tube body 400 through the water outlet head 605, thereby achieving automatic cooling of the core tube body 400 after the rough texture has been processed.
[0051] Please refer to this carefully. Figure 8 , Figure 9A rectangular box 601 has a drive mechanism 700 on its upper surface for driving the reciprocating rotation of the mesh ring 603. The drive mechanism 700 includes a limiting rod 701 fixed to the surface of the rectangular box 601, and a second reciprocating threaded post 702 fixed to the surface of the rotating rod 609 and corresponding to the limiting rod 701. A lifting block 703 is slidably disposed on the surface of the limiting rod 701, and the upper surface of the lifting block 703 has a second threaded hole that is threadedly connected to the outer surface of the second reciprocating threaded post 702. A rotating groove is provided at the end of 03. A straight cylinder 704 is rotatably mounted on the inner wall of the rotating groove via a first rotating shaft. A rotating frame 705 is fixedly mounted on the surface of the mesh ring 603. A straight rod 706 is rotatably mounted on the inner wall of the rotating frame 705 via a second rotating shaft. The straight rod 706 is slidably connected to the inner wall of the straight cylinder 704. Fixed discs are fixedly mounted on the surfaces of both the straight cylinder 704 and the straight rod 706. Tension springs 707 are sleeved on the surfaces of both the straight cylinder 704 and the straight rod 706. The two ends of the tension springs 707 are fixedly connected to the surfaces of the two fixed discs respectively.
[0052] Specifically, during the rotation of the rotating rod 609, it can drive the second reciprocating threaded column 702 to rotate. The rotation of the second reciprocating threaded column 702 drives the lifting block 703 to move up and down automatically, so as to realize the purpose of automatic reciprocating rotation of the annular tube 604 inside the mesh ring 603, so that the water outlet head 605 can uniformly and fully spray water to cool the surface of the core tube.
[0053] In this invention, a driving mechanism 700 is provided. During the rotation of the rotating rod 609, the second reciprocating threaded column 702 is driven to rotate. The rotation of the second reciprocating threaded column 702 causes the lifting block 703 to move up and down automatically. When the lifting block 703 moves upward, it can drive one end of the straight cylinder 704 to move upward. The upward movement of one end of the straight cylinder 704 can drive the mesh ring 603 to rotate automatically at a specified angle through the straight rod 706. When the lifting block 703 moves downward, it can drive the mesh ring 603 to rotate and reset. This achieves the purpose of automatic reciprocating rotation of the annular tube 604 inside the mesh ring 603, so that the water outlet 605 can uniformly and fully spray water to cool the surface of the core tube.
[0054] Working principle: When roughening the surface texture of the core tube, the rotation of the third motor 303 rotates one roller. The rotation of this roller, under the action of the two third toothed discs 304, drives the two traction rubber rollers 302 to rotate in opposite directions, realizing the automatic conveying of the core tube body 400. This allows the core tube body 400 extruded from the extruder to pass between the two first forming templates 204 and the two second forming templates 208. Simultaneously, the first motor 206 and the second motor 2010 are started respectively. The rotation of the first motor 206 and the second motor 2010 can drive the rotation of one first roller 203 and the second roller 207 respectively, and under the action of the two first toothed discs 205 and the second toothed disc 209 respectively, they drive the two first forming templates. The first forming template 204 and the two second forming templates 208 rotate in opposite directions, thereby enabling the two first forming templates 204 and the two second forming templates 208 to automatically imprint textures on the surface of the core tube body 400. This allows the device to process a uniformly distributed rough texture on the surface of the core tube body 400 through the cooperation of the first forming templates 204 and the second forming templates 208, improving the anti-slip effect when the core tube body 400 is wound with film or paper. Furthermore, when the rotation of the first motor 206 drives the two first forming templates 204 to rotate in opposite directions to process the texture on the surface of the core tube body 400, the rotation of the first roller 203 drives the large transmission wheel 6011 to rotate. The rotation of the large transmission wheel 6011 is transmitted through a transmission... The belt 6012 drives the small transmission wheel 6010 and the rotating rod 609 to rotate at an accelerated speed. The rotation of the rotating rod 609 drives the first reciprocating threaded column 6013 to rotate. The rotation of the first reciprocating threaded column 6013 drives the rectangular plate 606 to move up and down reciprocally. The up and down reciprocating movement of the rectangular plate 606 can drive the sealing plate 607 to move up and down reciprocally via the push rod 608. When the sealing plate 607 moves upward, it can draw water from the water collection tank 6014 through the water suction pipe 6016, cool it through the heat exchange cooler 6015, and then draw it into the rectangular box 601. When the sealing plate 607 moves downward, it can deliver the cooling water to the annular pipe 604 through the water outlet pipe 6017, and spray it onto the surface of the core tube body 400 through the water outlet head 605. The main body 400 of the core tube after roughening is automatically cooled. At the same time, during the rotation of the rotating rod 609, the second reciprocating threaded column 702 is driven to rotate. The rotation of the second reciprocating threaded column 702 drives the lifting block 703 to move up and down automatically. When the lifting block 703 moves upward, it can drive one end of the straight cylinder 704 to move upward. The upward movement of one end of the straight cylinder 704 can drive the mesh ring 603 to rotate automatically at a specified angle through the straight rod 706. When the lifting block 703 moves downward, it can drive the mesh ring 603 to rotate and reset. This achieves the purpose of automatic reciprocating rotation of the annular tube 604 inside the mesh ring 603, so that the water outlet 605 can evenly and fully spray water to cool the surface of the core tube.
