Description

Technical Field

[0001] This utility model relates to the technical field of roll changing devices, and in particular to a high-pressure water needle roll changing device. Background Technology

[0002] The papermaking process and its subsequent processing involve winding, rewinding, and other processes. These processes all require changing rolls, which necessitates the use of a roll-changing device to assist in the roll changing.

[0003] In practical applications, the existing water jet rewinding devices have relatively complete structures and functions, and can meet basic usage requirements. However, the following problems still exist:

[0004] Traditional roll changing methods utilize paper tape or air blowing to tear the paper web. These methods are limited by paper machine speed, basis weight, and fiber orientation. The process is uncontrollable; torn folds and overlapping paper ends can unevenly wrap around the roll core. Furthermore, flying paper scraps easily return to the new roll and are difficult to control. All these factors lead to low roll changing efficiency, excessive waste at the bottom of the roll, and negatively impact paper mill profits.

[0005] Therefore, this utility model provides a high-pressure water needle roll changing device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-pressure water needle roll changing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure water jet rewinding device, comprising a base plate, a mounting frame fixedly connected to the top of the base plate, a first motor provided on one side of the mounting frame, a rewinding roller fixedly connected to the output end of the first motor by bolts, two second mounting plates symmetrically fixedly connected to the top of the base plate, a feeding roller rotatably connected between the two second mounting plates, a water jet cutting structure provided on one side of the mounting frame, a glue spraying structure provided on one side of the water jet cutting structure, a high-pressure pump structure provided on the top of the base plate, and a control cabinet fixedly installed on the top of the base plate.

[0008] In a preferred embodiment, the waterjet cutting structure includes a connecting block. One side of the connecting block is fixedly connected to one side of the mounting bracket, and a rectangular blade holder is fixedly connected to the other side of the connecting block. A servo motor is provided on one side of the rectangular blade holder, and a threaded rod is fixedly connected to the output end of the servo motor. A threaded hole block is threadedly connected to the outer surface of the threaded rod, and the outer surface of the threaded hole block is slidably connected to the inner wall of the rectangular blade holder. A connecting rod is fixedly connected to the bottom of the threaded hole block, and a blade head is fixedly connected to the bottom of the connecting rod.

[0009] The technical effect of adopting the above-mentioned further solution is as follows: In order to ensure high-speed and stable operation, the high-pressure water pipe is tensioned along with the moving cutter head, and the high-pressure pump structure provides a reliable high-pressure cutting water source. This device can not only realize a fast and efficient roll changing process, but also connect with other automatic control systems in the factory to achieve truly fully automatic operation. Driven by a servo motor, it completes the transverse cutting of paper by driving the cutter heads to move in opposite directions.

[0010] In a preferred embodiment, the glue spraying structure includes a glue cylinder, which is fixedly connected to a rectangular blade holder. A piston pump is fixedly installed at the bottom of the glue cylinder. A connecting plate is fixedly connected to the outer surface of the connecting rod, and a glue gun is fixedly connected to one side of the connecting plate.

[0011] The technical effect of adopting the above-mentioned further solution is: to provide adhesive to the paper surface when water-cutting paper, so as to ensure that the paper surface can adhere to the roller surface when cutting the paper. The system uses air pressure to control the piston pump to draw in the adhesive and maintain precise and uniform pressure and stable glue output. It also ensures that after the piston pump is disconnected from the compressed air, the internal pressure of the glue machine is released back to the glue cylinder, thus ensuring safety.

[0012] In a preferred embodiment, the high-pressure pump structure includes a water tank, which is fixedly connected to the top of the base plate. A high-pressure pump is fixedly installed on the top of the water tank. The inlet and outlet ends of the high-pressure pump are respectively connected to an inlet pipe and an outlet pipe. The inlet pipe is connected to the water tank, and the outlet pipe is connected to the cutter head.

[0013] The technical effect of adopting the above-mentioned further solution is that the high-pressure pump uses an oil-water booster pump to achieve ultra-high pressure, so as to meet the pressure and flow rate requirements of the cutting water.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. Used in toilet paper machines;

[0016] 2. Eliminate paper damage caused by debris from air-blowing during roll changing and by wrinkles in the roll bottom paper;

[0017] 3. Eliminate paper damage at the bottom of the roller caused by paper tape indentation during paper tape changeover;

[0018] 4. The roll change success rate is higher than 99%, and there is very little paper damage at the bottom of the roll.

[0019] 5. Paper yield increases by 0.5%-3%, resulting in a faster return on investment;

[0020] 6. The fully automated roll changing process eliminates human error and safety hazards. Attached Figure Description

[0033] 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.

[0034] like Figures 1-6As shown, this embodiment provides a technical solution: a high-pressure water jet rewinding device, including a base plate 1, a mounting frame 2 fixedly connected to the top of the base plate 1, a first motor 5 provided on one side of the mounting frame 2, a rewinding roller 4 fixedly connected to the output end of the first motor 5 by bolts, two second mounting plates 6 symmetrically fixedly connected to the top of the base plate 1, a feeding roller 10 rotatably connected between the two second mounting plates 6, a water jet cutting structure 7 provided on one side of the mounting frame 1, a glue spraying structure 8 provided on one side of the water jet cutting structure 7, a high-pressure pump structure 9 provided on the top of the base plate 1, and a control cabinet 3 fixedly installed on the top of the base plate 1. The water jet automatic rewinding process is high-speed, clean and controllable throughout the entire rewinding process. The newly replaced paper roll has almost no wrinkles from the first layer, the rewinding surface is flat, and the paper loss rate is reduced. The control cabinet 3 uses a PLC controller, process software, sensors and actuators to drive, measure and control the system, realizing centralized monitoring of the entire system.

[0035] Going further, such as Figures 2-5 As shown: The waterjet cutting structure 7 includes a connecting block 71. One side of the connecting block 71 is fixedly connected to one side of the mounting bracket 2, and a rectangular blade holder 72 is fixedly connected to the other side of the connecting block 71. A servo motor 73 is provided on one side of the rectangular blade holder 72. A threaded rod 74 is fixedly connected to the output end of the servo motor 73. A threaded hole block 75 is threadedly connected to the outer surface of the threaded rod 74. The outer surface of the threaded hole block 75 is slidably connected to the inner wall of the rectangular blade holder 72. A connecting rod 76 is fixedly connected to the bottom of the threaded hole block 75, and a blade head 77 is fixedly connected to the bottom of the connecting rod 76. In order to ensure high-speed and stable operation, the high-pressure water pipe is tensioned along with the moving blade head 77. The high-pressure pump structure 9 provides a reliable high-pressure cutting water source. This device can not only realize a fast and efficient roll changing process, but also connect with other automatic control systems in the factory to achieve truly fully automatic operation. Driven by the servo motor 73, the blade head 77 moves in opposite directions to complete the transverse cutting of the paper.

[0036] The above solutions also have the problem of paper surface and roller surface easily separating during waterjet cutting, such as... Figures 2-5 As shown: In this solution, the glue spraying structure 8 includes a glue cylinder 81, which is fixedly connected to a rectangular knife holder 72. A piston pump 82 is fixedly installed at the bottom of the glue cylinder 81. A connecting plate 83 is fixedly connected to the outer surface of the connecting rod 76. A glue gun 84 is fixedly connected to one side of the connecting plate 83. When water-cutting paper, glue is provided to the paper surface to ensure that the paper surface can adhere to the roller surface when cutting the paper. The system controls the piston pump 82 through air pressure to draw glue and maintain precise and uniform pressure and stable glue output. After the compressed air of the piston pump 82 is disconnected, the internal pressure of the glue machine is released back to the glue cylinder 81 to ensure safety.

[0037] The above solutions also have the problem that insufficient water pressure can easily cause the cutter head to fail to cut, such as... Figure 1 and Figure 2 As shown, the high-pressure pump structure 9 includes a water tank 91, which is fixedly connected to the top of the base plate 1. A high-pressure pump 92 is fixedly installed on the top of the water tank 91. The inlet and outlet ends of the high-pressure pump 92 are respectively connected to an inlet pipe 93 and an outlet pipe 94. The inlet pipe 93 is connected to the water tank 91, and the outlet pipe 94 is connected to the cutter head 77. The high-pressure pump 92 uses an oil-water booster pump to achieve ultra-high pressure to meet the pressure and flow rate requirements of the cutting water.

[0038] Working principle:

[0039] like Figure 1-6 As shown:

[0040] In use, the paper roll is passed around the changing roller 4. At this time, the first motor 5 is started, so that the changing roller 4 can rotate. At this time, the servo motor 73 is started, so that the threaded rod 74 can drive the screw hole block 75 to move, which in turn can drive the cutter head 77 to move. At this time, the high pressure pump 92 can be started, so that the high pressure pump 92 can guide water from the water inlet pipe 93 to the water outlet pipe 94, and then flow to the nozzle to form high pressure cutting. At this time, the piston pump 82 is started, so that the glue can be sprayed on the cutting part, so that the paper surface and the roller surface can be bonded.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
