Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, in particular to a tube rolling machine for paper tube production. Background Art

[0002] Paper tube is a hollow cylindrical paper product, usually made of paper or cardboard. It is light, strong and low-cost. Paper tubes are usually used for packaging, transportation and storage of rolled items, such as textiles, plastic films, metal foils, etc. In the process of paper tube production, a tube rolling machine is usually needed to roll the paper into a tube. The tube rolling machine can accurately control the diameter, length and wall thickness of the paper tube according to the preset parameters to ensure the production of paper tubes that meet the specifications. The paper tube machine plays a key role in paper tube production, which can improve production efficiency and ensure product quality.

[0003] Traditional paper tube machines are usually composed of a frame, a paper supply system, a glue coating system and a tube rolling roller. The frame is the supporting structure of the entire machine. The paper supply system is used to provide paper or cardboard materials. The glue coating system applies glue on the paper to ensure that the paper tube can be bonded when it is rolled into a tube. Then, the paper is rolled into a paper tube shape by driving the tube rolling roller, thereby achieving efficient production of paper tubes.

[0004] However, the tube rolling roller part of the traditional paper tube machine is usually fixed by bolts or the like. This makes the disassembly and installation steps during the replacement process relatively cumbersome when the tube rolling roller is worn out after long-term use and needs maintenance and replacement. During disassembly, it is necessary to loosen multiple bolts, adjust the position and fix it again, which increases the time cost. When the paper rolling roller needs to be replaced or maintained frequently, this fixing method will lead to reduced production efficiency and increased downtime. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 3-Figure 5 The utility model provides an embodiment: a tube reel for paper tube production, comprising a support frame 1, a hollow column 2 is rotatably connected inside the support frame 1, a winding roller 3 is rotatably connected inside the support frame 1, a connecting buckle 4 is fixedly connected to one end of the winding roller 3, the connecting buckle 4 is slidably connected inside the hollow column 2, a first clamping block 5 is slidably connected inside the hollow column 2, a second clamping block 6 is slidably connected inside the hollow column 2, a bidirectional threaded rod 7 is threadedly connected inside the first clamping block 5, the second clamping block 6 is threadedly connected to the outer wall of the bidirectional threaded rod 7, a connecting column 8 is slidably connected inside the first clamping block 5, and the second clamping block 6 is slidably connected to the connecting column 8 The outer wall of the connecting column 8 is sleeved with a spring 9, one end of the spring 9 is fixedly connected to one end of the first clamping block 5, and the other end of the first clamping block 5 is fixedly connected to one end of the second clamping block 6. The outer wall of the winding roller 3 is provided with a connecting component, and the connecting component includes a hollow gear 13, and the hollow gear 13 is internally rotatably connected to the outer wall of the winding roller 3. The support frame 1 is internally rotatably connected to two front and rear symmetrical guide rollers 12, and a first motor 10 is fixedly connected to one side of the support frame 1. The output end of the first motor 10 is fixedly connected to the first gear 11, and the first gear 11 is meshed with the hollow gear 13. The outer walls of the guide rollers 12 are all rotatably connected to the inside of the first gear 11.

[0035] Specifically, when the winding roller 3 is worn and needs to be disassembled and replaced, first, since the hollow column 2 is connected to the inside of one side of the support frame 1, and an opening that matches the size of the winding roller 3 is opened inside the other side of the support frame 1, the winding roller 3 can be directly inserted into the inside of the support frame 1 from the opening during installation, and the connecting buckle 4 at one end of it is inserted into the inside of the hollow column 2 to ensure a firm connection. Subsequently, by rotating the bidirectional threaded rod 7, the first clamping block 5 and the second clamping block 6 acting on the outer wall are moved to the specified position. At the same time, this movement process compresses the connected spring 9 to increase the fixing force. Through the movement of the first clamping block 5 and the second clamping block 6, the connecting buckle 4 is finally It is finally stuck inside and fixed on the hollow column 2, ensuring the stability and reliability of the connection. After the installation is completed, the hollow gear 13 is connected to the winding roller 3 through the keyway connection method in the prior art, so that it is sleeved on the outer wall of the winding roller 3 and meshed with the two first gears 11 rotating on the side walls of the support frame 1, which is convenient for subsequent driving. During disassembly, the winding roller 3 is loosened by rotating the two-way threaded rod 7, and then the hollow gear 13 can be removed from the outer wall of the winding roller 3, so that the winding roller 3 can be directly pulled out from the inside of the support frame 1, or the winding roller 3 and the hollow gear 13 can be directly taken out together to complete the disassembly, so that the replacement process of the winding roller 3 is fast and effective.

[0036] Reference Figure 1 , Figure 2 and Figure 6 A support plate 24 is fixedly connected to one side of the support frame 1, and an empty groove 19 is opened inside the support plate 24. A second motor 14 is fixedly connected to one side of the support plate 24, and a second gear 15 is fixedly connected to the output end of the second motor 14. A third gear 18 is rotatably connected to one side of the second motor 14. The second gear 15 and the third gear 18 are meshed with each other, and one end of the second gear 15 and the third gear 18 are fixedly connected to a slider 16. Two symmetrical rotating rods 17 are rotatably connected to one side of the support plate 24, and the interior of the rotating rods 17 are slidably connected to the outer wall of the slider 16.

[0037] Specifically, when the paper is rolled up, the second gear 15 is first guided to rotate by the output of the second motor 14, thereby driving the third gear 18 meshing therewith, and then the coordinated movement of the third gear 18 and the second gear 15 drives the slider 16 to move, causing it to slide inside the rotating rod 17 and guide the rotating rod 17 to rotate, thereby achieving a driving effect.

[0038] Reference Figure 1 and Figure 6 A sliding column 20 is slidably connected inside the rotating rod 17, one end of the sliding column 20 is fixedly connected to a connecting block 22, one side of the support plate 24 is fixedly connected to a fixed frame 21, the connecting block 22 is slidably connected inside the fixed frame 21, and one side of the connecting block 22 is fixedly connected to a cutter 23.

[0039] Specifically, at the same time, the rotating rod 17 drives the connecting block 22 to slide inside the fixed frame 21 through the connected sliding column 20, and the movement of the connecting block 22 acts on the cutter 23, accurately positioning it at the required position, thereby ensuring accurate cutting of the paper, ensuring the stability and efficiency of the cutting process, and enabling the paper cutting to be automatically completed during winding, thereby achieving the effect of automatically cutting the paper during winding.

[0040] Working principle: when it is necessary to disassemble and replace the winding roller 3, first insert the connecting buckle 4 connected to one end of the winding roller 3 into the hollow column 2. When it moves to a certain position, the bidirectional threaded rod 7 is rotated so that it is forced to drive the first clamping block 5 and the second clamping block 6 of the outer wall to move in the same direction. At the same time, the first clamping block 5 and the second clamping block 6 are forced to squeeze and contract the spring 9 connected therebetween. Through the movement of the first clamping block 5 and the second clamping block 6, the connecting buckle 4 is clamped inside to fix it. When disassembling, after loosening the winding roller 3, through the keyway connection between the hollow gear 13 and the winding roller 3, it is only necessary to directly pull the hollow gear 13 and the winding roller 3 out of the support frame 1, thereby achieving the effect of quick disassembly and replacement of the winding roller 3. When the paper is rolled up, the second gear 15 is driven to rotate by the output end of the second motor 14, and the second gear 15 is forced to drive the third gear 18 meshing with it to rotate. At the same time, the third gear 18 and the second gear 15 drive the slider 16 connected at one end to rotate, and the slider 16 is forced to slide inside the rotating rod 17, so that the rotating rod 17 is forced to rotate. At the same time, the rotating rod 17 is also forced to drive the sliding column 20 connected to one side to slide, and the sliding column 20 is forced to drive the connecting block 22 connected at one end to slide inside the fixed frame 21, and the connecting block 22 is forced to drive the cutter 23 connected at one side to move, and the paper in between is cut by the movement of the cutter 23, thereby achieving the effect of automatically cutting paper when rolling up.
