Weak acid cleaning device before coiled material compression

Abstract

This utility model discloses a weak acid cleaning device for roll material before re-pressing, including a cleaning tank; pressure rollers symmetrically and rotatably disposed at the open end of the cleaning tank; a cleaning roller rotatably disposed at the open end of the cleaning tank and located between the pressure rollers; and a transmission assembly connecting the shaft ends of adjacent pressure rollers and the cleaning roller on the same side. The continuously conveyed roll material is pressed by the pressure rollers and passes through the inside of the cleaning tank. The conveying process of the roll material drives the pressure rollers to rotate, and the pressure rollers, in conjunction with the transmission assembly, drive the cleaning roller to rotate synchronously and in opposite directions. The outer wall of the cleaning roller contacts the roll material and generates friction. This utility model, by setting the cleaning roller and pressure roller to rotate synchronously and in opposite directions, causes the friction part of the outer wall of the cleaning roller to generate relative friction with the surface of the roll material, effectively enhancing the cleaning fluid's ability to remove impurities from the roll material surface and significantly improving cleaning efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of roll material processing technology, and in particular relates to a weak acid cleaning device for roll material before re-pressing. Background Technology

[0002] Acid cleaning of rolled materials before re-pressing is a surface treatment process mainly used to remove oxides, rust, oil, and other impurities from the surface of the rolled materials, ensuring that its surface cleanliness meets the requirements of subsequent processing. Traditional pickling equipment mostly adopts a static immersion structure, relying solely on the chemical action of the cleaning solution, resulting in low cleaning efficiency and difficulty in meeting the needs of high-speed continuous production. Utility Model Content

[0003] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0004] This utility model provides a weak acid cleaning device for roll material before re-pressing, comprising:

[0005] Cleaning pool;

[0006] Pressure rollers are symmetrically and rotatably arranged at the opening end of the cleaning tank;

[0007] A cleaning roller, which is rotatably disposed at the open end of the cleaning tank and located between the pressure rollers;

[0008] A transmission assembly, wherein the transmission assembly connects the shaft ends of adjacent pressure rollers and cleaning rollers located on the same side;

[0009] The continuously conveyed roll material is pressed by the pressure rollers and passes through the inside of the cleaning tank. The conveying process of the roll material drives the pressure rollers to rotate. The pressure rollers, together with the transmission components, drive the cleaning rollers to rotate synchronously and in opposite directions. The outer wall of the cleaning rollers comes into contact with the roll material and generates friction.

[0010] As a preferred embodiment of the above technical solution, the cleaning roller includes an inner substrate and a friction part sleeved on the outside of the substrate.

[0011] As a preferred embodiment of the above technical solution, the transmission assembly includes a first gear fixedly sleeved on a shaft at any end of the pressure roller, and a connecting shaft rotatably mounted on the outer wall of the cleaning tank and close to the first gear. A second gear is fixedly sleeved on the outside of the connecting shaft, and the second gear meshes with the first gear. Pulleys are fixedly sleeved on the outside of the connecting shaft and on the end shaft of the cleaning roller adjacent to the pressure roller, and the same belt is tightly sleeved on the outside of the pulleys.

[0012] As a preferred embodiment of the above technical solution, two cleaning rollers are symmetrically arranged, and two sets of transmission components are provided, which are respectively connected to the shafts of the adjacent left pressure roller and the cleaning roller at the same end, and the shafts of the adjacent right pressure roller and the cleaning roller at the same end.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention sets the cleaning roller and the pressure roller to rotate synchronously in opposite directions, so that the friction part of the outer wall of the cleaning roller generates relative friction with the surface of the roll material. This effectively enhances the cleaning fluid's ability to remove impurities from the surface of the roll material, significantly improving cleaning efficiency. Moreover, the cleaning roller is powered by the pressure roller during the roll material conveying process, eliminating the need for an additional drive motor, thus achieving efficient energy utilization and reducing energy consumption.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The diagram shown is an overall schematic diagram (top view) of the cleaning device in the embodiment. Figure 2 The diagram shown is a cross-sectional view (front view) of the cleaning device in the embodiment; Figure 3 The diagram shown is a schematic representation of the engagement of the transmission components in the embodiment (front view).

[0022] This device includes:

[0023] Cleaning pool 10;

[0024] Pressure roller 20 is symmetrically and rotatably arranged at the opening end of the cleaning tank 10;

[0025] The cleaning roller 30 is rotatably disposed at the open end of the cleaning tank 10 and located between the pressure rollers 20;

[0026] The transmission assembly connects the shaft ends of adjacent pressure rollers 20 and cleaning rollers 30 located on the same side.

[0027] The continuously conveyed roll 1 is pressed by the pressure roller 20 and passes through the inside of the cleaning tank 10. The conveying process of the roll 1 drives the pressure roller 20 to rotate. The pressure roller 20, in conjunction with the transmission component, drives the cleaning roller 30 to rotate synchronously and in opposite directions. The outer wall of the cleaning roller 30 adheres to the roll 1 and generates friction.

[0028] Specifically, the shafts at both ends of the pressure roller 20 and the cleaning roller 30 are installed at the open end of the cleaning tank 10 through bearing seats. There are also two cleaning rollers 30 symmetrically arranged. There are two sets of transmission components, which are respectively connected to the shafts at the same end of the adjacent pressure roller 20 and the cleaning roller 30 on the left, and the shafts at the same end of the adjacent pressure roller 20 and the cleaning roller 30 on the right.

[0029] The cleaning tank 10 contains a weak acid cleaning solution for cleaning oxides, oil stains, or other impurities on the surface of the roll material 1. The pressure roller 20 presses the roll material 1 so that it is completely immersed below the liquid surface in the cleaning tank 10. The pressure roller 20 drives the transmission component to operate through the friction between itself and the roll material 1. The transmission component transmits the rotational power of the pressure roller 20 to the cleaning roller 30, causing the cleaning roller 30 to rotate synchronously in the opposite direction. The cleaning roller 30 uses the relative movement between its outer wall and the surface of the roll material 1 to generate friction, which, together with the action of the cleaning solution, removes contaminants from the surface of the roll material 1 and enhances the cleaning effect.

[0030] like Figure 2 As shown, Figure 2 The diagram shown is a cross-sectional view (front view) of the cleaning device in the embodiment;

[0031] The cleaning roller 30 includes an inner base 31 and a friction part 32 sleeved on the outside of the base 31.

[0032] The substrate 31 is the supporting frame of the cleaning roller 30. The friction part 32 is in direct contact with the surface of the roll 1. Friction is generated through relative motion to enhance the cleaning effect. The friction part 32 can be made of ceramic coating, such as alumina, zirconium oxide and other ceramic materials, which are acid resistant and can provide better wear resistance.

[0033] like Figure 1 , Figure 3 As shown, Figure 1 The diagram shown is an overall schematic diagram (top view) of the cleaning device in the embodiment. Figure 3 The diagram shown is a schematic representation of the engagement of the transmission components in the embodiment (front view).

[0034] The transmission components include:

[0035] The first gear 41 is fixedly sleeved on the shaft at any end of the pressure roller 20.

[0036] It also includes a connecting shaft 42 rotatably mounted on the outer wall of the cleaning tank 10 and close to the first gear 41. A second gear 43 is fixedly sleeved on the outside of the connecting shaft 42. The second gear 43 meshes with the first gear 41. Pulleys 44 are fixedly sleeved on the outside of the connecting shaft 42 and on the end shaft of the cleaning roller 30 adjacent to the pressure roller 20. The same belt 45 is tightly sleeved on the outside of the pulleys 44.

[0037] During the conveying process, the roll 1 passes through the pressure roller 20, which drives the pressure roller 20 to rotate. The rotation of the pressure roller 20 is transmitted to the second gear 43 through the first gear 41. The rotation of the second gear 43 causes the connecting shaft 42 to rotate. Finally, through the pulley 44 and belt 45 installed on the connecting shaft 42 and the cleaning roller 30, the cleaning roller 30 is rotated synchronously in opposite directions.

[0038] Working principle: When using this device to clean the roll material 1, the roll material 1 is continuously conveyed forward under the drive of the external traction equipment. The roll material 1 passes under the pressure roller 20 and enters the cleaning tank 10. The continuous movement of the roll material 1 drives the pressure roller 20 to rotate. The rotation of the pressure roller 20 is transmitted to the second gear 43 through the first gear 41. The rotation of the second gear 43 causes the connecting shaft 42 to rotate. Finally, through the pulley 44 and belt 45 installed on the connecting shaft 42 and the cleaning roller 30, the cleaning roller 30 is driven to rotate synchronously in the opposite direction. The friction part 32 of the cleaning roller 30 is in close contact with the surface of the roll material 1 and generates relative sliding friction with it in the cleaning liquid environment, effectively removing the adhering substances on the surface of the roll material 1. After cleaning, the roll material 1 leaves the cleaning tank 10 and enters the subsequent process steps (such as drying, re-pressing, etc.).

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
