Description

Technical Field

[0001] This utility model relates to the field of paper production equipment technology, and in particular to an automated paper cutting water needle device. Background Technology

[0002] In the paper production process, high-pressure water jets are ejected at high speed from nozzles to form water jets for cutting paper, meeting the production requirements for processing paper of different specifications. Currently, the water jet cutting process for paper has the following problems: water jet diffusion causes the cleanliness of the paper cut edges to not meet production requirements, which needs to be improved. Utility Model Content

[0003] In order to overcome the influence of water temperature on paper cutting cuts in the existing technology, the purpose of this utility model is to provide an automated paper cutting water needle device to ensure the controllability of paper cutting quality.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An automated paper-cutting water jet device includes a water inlet pipe, an exhaust valve, a nozzle, a heating element, and a shielding assembly. The water inlet pipe is connected to the nozzle, the heating element is disposed in the water inlet pipe and spaced apart from the nozzle, the exhaust valve is connected to the water inlet pipe, and is disposed between the heating element and the nozzle, with the exhaust valve located above the nozzle. The heating element includes a protective sleeve and a heating wire. The protective sleeve is fitted onto the water inlet pipe and spaced apart from it. The heating wire is located between the protective sleeve and the water inlet pipe and close to it.

[0005] Furthermore, the distance between the protective sleeve and the heating wire is set.

[0006] Furthermore, the heating element also includes a heat-conducting ring, which is sleeved on and fits against the water inlet pipe, and the heating wire is wound around the heat-conducting ring.

[0007] Furthermore, the shielding assembly includes a lifting drive, a mounting plate, and a splash guard. The lifting drive is located on the water inlet pipe and drives the mounting plate to move up and down. The splash guard is fixed to the mounting plate and is arranged around the nozzle.

[0008] Furthermore, the splash guard has a concave arc surface, and the central axis of the concave arc surface is oriented towards the nozzle.

[0009] Furthermore, the shielding assembly is also provided with a plurality of spheres, which are rotatably connected to the bottom end of the splash guard.

[0010] Furthermore, the nozzle includes an inlet section and an outlet section. The inlet section is connected to an inlet pipe, and the outlet section is screwed to the inlet section. The diameter of the inlet of the outlet section is larger than the diameter of the outlet of the outlet section.

[0011] The beneficial effects of this utility model are as follows: by heating the water inlet pipe through the heating element, the high-pressure water flow in the water inlet pipe is heated through heat transfer, thereby ensuring that the temperature of the water jet formed by the water jet ejected through the nozzle is within the preset range, which reduces the viscosity of the water, improves the fluidity of the water, and makes the water jet spray more concentrated. The warm water softens the paper fibers, ensuring the stress state of the paper and the cleanliness of the cut edges, thus meeting production requirements. Attached Figure Description

Detailed Implementation

[0014] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0015] Please see Figures 1 to 3 The present invention discloses an automated paper-cutting water needle device, comprising a water inlet pipe 1, an exhaust valve 2, a nozzle 3, a heating element 4, and a baffle assembly 5. The water inlet pipe 1 is connected to the nozzle 3. The heating element 4 is disposed on the water inlet pipe 1 and spaced apart from the nozzle 3. The exhaust valve 2 is connected to the water inlet pipe 1 and is disposed between the heating element 4 and the nozzle 3. The exhaust valve 2 is located above the nozzle 3. The heating element 4 includes a protective sleeve 41 and a heating wire 42. The protective sleeve 41 is fitted onto the water inlet pipe 1 and spaced apart from the water inlet pipe 1. The heating wire 42 is located between the protective sleeve 41 and the water inlet pipe 1 and is close to the water inlet pipe 1.

[0016] Specifically, in this embodiment, the water inlet pipe 1 is connected to an external high-pressure water source. The external high-pressure water flows through the water inlet pipe 1 and enters the nozzle 3. The high-pressure water is ejected outward through the nozzle 3 to form water needles. The water needles cut the paper. Preferably, a heating element 4 is installed on the outer surface of the water inlet pipe 1. The external high-pressure water flowing through the water inlet pipe 1 is heated by heat transfer, so that the ejected high-pressure water reaches a preset temperature. The water needles cut the paper, improving the quality of the paper cut. An exhaust valve 2 is provided between the heating element 4 and the nozzle 3. The exhaust valve 2 includes a pipe body 21 and a filter element 22. The pipe body 21 is connected to the water inlet pipe 1. The air in the water inlet pipe 1 enters the exhaust valve 2 upward and is discharged, reducing the amount of air bubbles in the water ejected outward from the nozzle 3, further ensuring the cutting quality of the paper cut. The baffle assembly 5 is spaced apart from the nozzle 3. The baffle assembly 5 blocks the paper hair generated during the cutting process, preventing the paper hair from splashing onto the paper, further improving the stability of the paper cutting quality.

[0017] Heating element 4 heats water inlet pipe 1, and heat transfer heats the high-pressure water flow in water inlet pipe 1, thereby ensuring that the temperature of the water jet formed by the water jet ejected through nozzle 3 is within the preset range, which reduces the viscosity of water, improves the fluidity of water, and makes the water jet spray more concentrated. Warm water softens paper fibers, ensuring the stress state of paper and the cleanliness of cut edges, thus meeting production requirements.

[0018] The protective sleeve 41 is spaced apart from the heating wire 42, and the heat is insulated by air. This structure has a heat preservation effect and prevents the protective sleeve 4 from transferring heat outward.

[0019] The heating element 4 also includes a heat-conducting ring 43, which is sleeved on and fits against the water inlet pipe 1. The heating wire 42 is wound around the heat-conducting ring 43. There are multiple heat-conducting rings 43, which are arranged sequentially along the central axis of the water inlet pipe 1. The heat-conducting rings 43 are in contact with the outer surface of the water inlet pipe 1, so that the heat generated by the heating wire 42 is first transferred to the heat-conducting ring 43, and then the heat-conducting ring 43 transfers the heat to the water inlet pipe 1, ensuring the uniformity of heating per unit area of ​​the water inlet pipe 1, and further ensuring the temperature consistency of the high-pressure water flow per unit volume in the water inlet pipe 1.

[0020] The shielding assembly 5 includes a lifting drive 51, a mounting plate 52, and a splash guard 53. The lifting drive 51 is located on the water inlet pipe 1 and drives the mounting plate 52 to rise and fall. The splash guard 53 is fixed to the mounting plate 52 and is arranged around the nozzle 3. The lifting drive 51 drives the mounting plate 52 and the splash guard 53 to rise and fall synchronously. The longitudinal spatial position of the splash guard 53 can be adjusted according to the actual situation to meet different production requirements.

[0021] The splash guard 53 is provided with a concave arc surface 531. The central axis of the concave arc surface 531 is oriented close to the nozzle 3. Preferably, the splash guard 53 has a 270° arc structure. The central axis of the splash guard 53 coincides with the central axis of the nozzle 3. The paper fibers generated during the water jet cutting process adhere to the concave arc surface 531, effectively preventing the paper fibers from adhering to the paper surface.

[0022] The shielding component 5 is also provided with a plurality of spheres 54, which are rotatably connected to the bottom end of the splash guard 53. The splash guard 53 moves synchronously with the nozzle 3. The spheres 54 act on the paper surface and form point contact with the paper surface, thereby reducing the pressure of the shielding component 5 on the paper surface and reducing damage to the paper surface.

[0023] The nozzle 3 includes an inlet section 31 and an outlet section 32. The inlet section 31 is connected to the inlet pipe 1, and the outlet section 32 is screwed to the inlet section 31. The diameter of the inlet of the outlet section 32 is larger than the diameter of the outlet of the outlet section 32, which concentrates the water flow and increases the water pressure.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
