Description

Technical Field

[0001] The utility model relates to a sealing device for a water-soaking roller, in particular to a device for sealing a squeezing roller when the surface water of a metal plate strip is squeezed out after a cleaning process. Background Art

[0002] During the hot-dip galvanizing, color coating or other pre-treatment processes of metal plates and strips, the surface of the metal plates and strips needs to be cleaned, mainly by brushing the plates and strips with upper and lower brush rollers. After cleaning, the upper and lower rollers are needed to squeeze the cleaned metal plates and strips. This process is carried out in a water tank, and the support bearings of the two rollers are located outside the water tank. Since the squeezing rollers need to be lifted and lowered during the production process for position adjustment, the steel plate sealing doors currently used in the industry have "U"-shaped holes on them to ensure that the rollers can move up and down in the sealing door. However, since this type of sealing door retains a large space for the rollers to move, the sealing door cannot form a completely sealed effect, causing the liquid water in the water tank to overflow from the "U"-shaped hole, greatly reducing the sealing effect. Utility Model Content

[0003] In order to solve the problem in the above-mentioned prior art that the squeezing roller has poor sealing effect on the pretreatment liquid during operation, the utility model provides a new water vapor sealing door device, including a sealing door frame, and a sealing door arranged in the sealing door frame, characterized in that the sealing door is a flexible sealing door, and the roller shaft head required for sealing can directly pass through the flexible sealing door.

[0004] Preferably, the flexible sealing door can be set using a soft brush.

[0005] By optimizing the rigid sealing door in the prior art to a flexible sealing door, the "U"-shaped perforation setting that must be reserved for the squeezing roller to move up and down is completely avoided, thereby avoiding the phenomenon of water vapor overflowing from the "U"-shaped hole. In addition, the soft brush material is preferably used as a flexible sealing door, which can be easily installed and embedded in the position of the squeezing roller head, and the soft brush is in full contact with the squeezing roller shaft head, and there is no extra space reserved between the two, which completely prevents water vapor from overflowing into the bearing position and the external environment. In addition, this kind of soft brush flexible sealing door does not limit the adjustment space of the squeezing roller to move up and down. As the squeezing roller is adjusted up and down, the soft brush always maintains full contact with the squeezing roller shaft head, leaving no extra space, and always maintains full sealing of the squeezing roller body.

[0006] Preferably, at least two layers of soft brush sealing doors are arranged in the sealing door frame.

[0007] In order to achieve a better sealing effect, multiple layers of soft brush sealing doors can be set in the sealing door frame. The first layer is mainly used to prevent liquid water from splashing out, the second layer is mainly used to prevent gaseous water from overflowing and some liquid water from splashing out, and the third layer is mainly used to prevent additional gaseous water from overflowing. The number of soft brush layers can be adjusted according to the actual situation of the metal strip production line.

[0008] Preferably, a roller baffle is arranged on the roller shaft head that needs to be sealed.

[0009] In order to prevent water from flowing along the roller body to the shaft head and then flowing from the shaft head to the external bearing, a roller baffle is installed on the shaft head of the squeeze roller. The baffle can be made of rubber with a hole in the middle. It is installed on the shaft head and can move up and down with the up and down adjustment of the squeeze roller without affecting the working action of the squeeze roller.

[0010] Preferably, the roller baffles and the soft brush sealing doors are alternately arranged on the roller shaft head.

[0011] In order to achieve a better sealing effect, a layer of roller baffle, a layer of soft brush sealing door, a second layer of roller baffle, and a second layer of soft brush sealing door can be arranged in sequence from the roller body to the outside at the position of the squeeze roller shaft head. The roller baffle and soft brush sealing door can be arranged in multiple layers according to actual conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 A top view of a water vapor sealing door device provided by the present invention; DETAILED DESCRIPTION

[0014] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. This description is only used to explain the utility model, but not to limit the utility model.

[0015] With reference to the accompanying drawings, the implementation cases of the present invention are described below, so as to ensure that ordinary technicians in the field of the present invention can clearly understand the technical solution of the present invention.

[0016] like Figure 1 As shown, the present invention provides a water vapor sealing door device, which includes a sealing door frame 1, and a flexible sealing door, a soft brush sealing door 2, which is arranged in the sealing door frame 1. The soft brush sealing door 2 can be easily passed through by the upper roller 3 and the lower roller 4 of the squeezing roller, and the soft brush in the soft brush sealing door is in full contact with the squeezing roller, and there is no excess gap between the two.

[0017] like Figure 2As shown, in order to prevent liquid water from flowing along the upper roller 3 of the squeeze roller to the upper roller shaft head 5, and then flowing from the shaft head 5 to the outer bearing position 8, a roller baffle 6 is sleeved on the inner position of the upper roller shaft head 5, and the roller baffle 6 is made of rubber with a hole in the middle, which can be sleeved on the upper roller shaft head 5. Similarly, the shaft head position of the lower roller 4 is also sleeved with this roller baffle. In addition, two layers of soft brush sealing doors are set in the sealing door frame 1, from the inside to the outside, respectively, a first layer of soft brush sealing door 2, and a second layer of soft brush sealing door 7. The two layers of soft brush sealing doors are also passed through the upper roller 3 and the lower roller 4 of the squeeze roller, and are fixedly installed at the roller shaft head position. In order to achieve a better sealing effect, two layers of roller baffles can be set on the roller shaft head, namely, a roller baffle 6 and a roller baffle 9, which play a double role in preventing water from overflowing.

[0018] In the early stage of the metal strip threading process, it is necessary to lift the upper roller 3 of the squeeze roller to facilitate the smooth passage of the metal strip. When the upper roller 3 of the squeeze roller is lifted upward, since the soft brush sealing door 2 adopts a flexible soft brush structure, as the upper roller 3 is lifted, the soft brush is always in full contact with the upper roller 3, there is no extra space for outflow, and it will not cause the displacement of the upper roller 3 to be restricted. Similarly, when the upper roller 3 is pressed down, the same effect is achieved. When the squeeze roller is working, as the upper roller 3 and the lower roller 4 of the squeeze roller rotate, the moisture on the surface of the metal strip is squeezed out and wiped. The soft brush sealing door layer 2 and the soft brush sealing door layer 7 set in the sealing door frame 1 effectively block and seal the splashed liquid water and the generated gaseous water, and there is no extra gap to cause the overflow of water. At the same time, the roller baffle 6 and the roller baffle 9 can effectively prevent the water from flowing out along the shaft head 5 to the outer bearing 8.

[0019] Furthermore, in the prior art, since a rigid seal is adopted, the roller shaft head must be inserted exactly into the "U"-shaped hole punched in advance in the rigid sealing door without any error, and the installation accuracy is required to be high, otherwise the installation cannot be completed. The water vapor sealing door device provided by the utility model effectively reduces the installation accuracy requirement for the squeeze roller due to the setting of a flexible soft brush, and the sealing effect is good without any reserved gap.

[0020] The above description is merely an exemplary description of the technical concept of the present invention, and a person skilled in the art of the present invention may make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, the embodiments shown in this specification and the accompanying drawings are not intended to limit the technical concept of the present invention, but are intended to illustrate the present invention, and the scope of the technical concept of the present invention is not limited to these embodiments. The scope of protection of the present invention shall be interpreted by the claims, and all technical concepts within the equivalent scope thereof shall be interpreted as included within the scope of the present invention.
