Description

Technical Field

[0001] This utility model relates to the field of corrugating machine technology, and in particular to a duct opening and closing device for an internal suction type corrugated wheel assembly. Background Technology

[0002] The internal suction type corrugated roller assembly of a corrugating machine uses air pressure inside the rollers to press the corrugated paper onto the upper corrugated rollers, thus producing single-face corrugated paper. The air pressure is generally output from a suction fan and then delivered to the corrugated roller assembly through ductwork. In actual production, different corrugated roller assemblies are used to produce single-face corrugated paper with different flute types. At this time, the air outlet of the corrugated roller assembly's hood and the ductwork must be manually disconnected to allow the corrugated roller assembly to be pulled out. When a new corrugated roller assembly enters, the air outlet of the hood must also be manually connected to the ductwork to guide air into the assembly. This operation is complex, time-consuming, and labor-intensive. Because the corrugated rollers are exposed to steam, their surface temperature is quite high, posing a risk of burns to operators. Furthermore, manual connection can easily cause air leakage. When air leakage occurs, insufficient airflow leads to defects such as dents and collapsed flute tips in the produced single-face corrugated paper, significantly reducing the production efficiency and quality of the corrugated board production line.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-5 As shown, a preferred embodiment of the present invention provides a duct opening and closing device for an internal suction corrugated wheel assembly, including an adapter pipe 1. The air inlet end of the adapter pipe 1 is connected to the air outlet of the air hood 5 of the corrugated wheel assembly. It is understood that the corrugated wheel assembly is existing technology. The specific air path between the air hood and the corrugated wheel will not be described in detail here. During operation, the air force at the air outlet of the air hood can be transmitted to the small holes around the corrugated wheel through the air path between the air hood and the corrugated wheel, thereby adsorbing the corrugated paper onto the corrugated wheel.

[0026] The opening and closing mechanism 2 includes a mounting base 21, a suction base 22, a connecting pipe 23, and a drive assembly 24. The mounting base 21 is fixed on the frame 6 of the corrugating machine. The suction base 22 is slidably mounted on the mounting base 21. The suction base 22 has a suction slot 221 and an air outlet slot 222 that are connected to each other. The suction slot 221 is opposite to the air outlet end of the adapter pipe 1. Generally, the ports of the suction slot 221 and the air outlet end of the adapter pipe 1 are aligned. The air outlet slot 222 is connected to the air inlet end of the connecting pipe 23. The connecting pipe 23 is a flexible hose. The drive assembly 24 is connected to the suction base 22. The drive assembly 24 can drive the suction base 22 to slide so that the suction slot 221 is sealed to the air outlet end of the adapter pipe 1, or to separate the suction slot 221 from the air outlet end of the adapter pipe 1. That is, the drive assembly 24 can drive the suction base 22 to move closer to or further away from the air outlet end of the adapter pipe 1.

[0027] The main air duct 3 is connected to the air outlet of the connecting pipe 23 and the air inlet of the suction fan 4, respectively. That is, the air outlet of the connecting pipe 23 is connected to the air inlet of the suction fan 4 through the main air duct 3.

[0028] The working principle of this embodiment is as follows: The suction seat 22 is slidably mounted on the mounting base 21. When the corrugating machine is working, the suction slot 221 is sealed to the air outlet of the adapter pipe 1. The air outlet of the air hood 5 of the corrugated wheel set is connected to the suction fan 4 through the adapter pipe 1, the suction seat 22, and the main air pipe 3 in sequence, thereby forming a closed suction air path. When the corrugated wheel set needs to be replaced, the control drive component 24 drives the adapter pipe 1 to slide, so that the suction slot 221 is separated from the air outlet of the adapter pipe 1. At this time, the suction air path between the air outlet of the air hood 5 of the corrugated wheel set and the suction fan 4 is disconnected, and the corrugated wheel replacement operation can be performed. After the replacement is completed, The drive assembly 24 drives the adapter pipe 1 to slide, so that the suction slot 221 is sealed to the air outlet of the adapter pipe 1, and the suction air path between the air outlet of the corrugated wheel assembly's hood 5 and the suction fan 4 is restored to closed. This device drives the suction seat 22 to slide through the drive assembly 24, so that the suction slot 221 is sealed to the air outlet of the adapter pipe 1, or so that the suction slot 221 is separated from the air outlet of the adapter pipe 1, thereby quickly realizing the connection or separation of the adapter pipe 1 and the suction seat 22, that is, realizing the opening and closing of the suction air path between the air outlet of the corrugated wheel assembly's hood 5 and the suction fan 4. The operation is simple and does not require manual connection or disconnection.

[0029] For example, the drive assembly 24 includes a cylinder mounting base 241 and a drive cylinder 242. The cylinder mounting base 241 is mounted on the frame 6 of the corrugating machine, and the drive cylinder 242 is mounted on the cylinder mounting base 241. The telescopic shaft of the drive cylinder 242 is arranged along the axial direction of the air outlet end of the adapter pipe 1 and is fixedly connected to the suction seat 22. The drive cylinder 242 can drive the suction seat 22 to slide along the axial direction of the air outlet end of the adapter pipe 1, that is, it can drive the suction seat 22 to approach the adapter pipe 1 to seal and connect with the air outlet end of the adapter pipe 1, or to move away from the adapter pipe 1 to separate from the air outlet end of the adapter pipe 1.

[0030] For example, the mounting base 21 is provided with a slide rail 25 arranged axially along the air outlet end of the adapter pipe 1, and the bottom of the suction seat 22 is slidably connected to the slide rail 25 to ensure that the suction seat 22 slides along the axis of the air outlet end of the adapter pipe 1 and prevents it from deviating.

[0031] For example, the air intake slot 221 is matched with the air outlet end of the adapter pipe 1, that is, the air outlet end of the adapter pipe 1 can be matched and inserted into the air intake slot 221 to ensure a sealed connection between the two.

[0032] For example, a sealing gasket 223 is provided inside the air intake slot 221. When the air outlet of the adapter pipe 1 is connected to the air intake slot 221, the air outlet of the adapter pipe 1 abuts against the sealing gasket 223 to ensure the airtightness when the air outlet of the adapter pipe 1 is connected to the air intake slot 221.

[0033] For example, the wind cover 5 of the corrugated wheel assembly is provided with air outlets at both ends and is connected to the adapter pipe 1 respectively. The opening and closing mechanism 2 is provided in two sets and corresponds one-to-one with the adapter pipe 1. That is, the air outlets at both ends of the corrugated wheel assembly can be connected to the suction fan 4 through the corresponding opening and closing mechanism 2.

[0034] For example, the main air duct 3 is fixed on both sides of the frame 6 of the corrugating machine. One end of the main air duct 3 is connected to the air inlet of the suction fan 4, and the other end of the main air duct 3 is a closed end. A branch pipe 31 is fixed in the middle of the main air duct 3. The middle of the branch pipe 31 is connected to the middle of the main air duct 3. The two ends of the branch pipe 31 are respectively connected to the air outlet of the connecting pipe 23. Specifically, the air outlet of the connecting pipe 23 in one of the opening and closing mechanisms 2 is connected to one end of the branch pipe 31, and the air outlet of the connecting pipe 23 in the other opening and closing mechanism 2 is connected to the other end of the branch pipe 31. That is, the two connecting pipes 23 are respectively connected to the main air duct 3 through the branch pipe 31.

[0035] For example, the air outlet 222 is connected to the air inlet of the connecting pipe 23 via a bend 26 for easy connection.

[0036] For example, the adapter pipe 1 is fixedly connected to the frame 6 of the corrugating machine to ensure the stability of the adapter pipe 1 and prevent the adapter pipe 1 from shifting and affecting its sealing connection with the suction slot 221.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
