Description

Technical Field

[0001] The invention relates to the field of strip steel processing, and in particular to a water retaining sealing mechanism for a working main beam slide rail. Background Art

[0002] Strip steel is a narrow, long steel plate widely used in the manufacture of welded pipes, clamps, washers, springs, saw blades, and razor blades. Its width typically ranges from 20 mm to 200 mm. Due to its length, strip steel is typically supplied in coils. During strip processing, surface rust must be removed. Currently, this is accomplished by grinding the strip surface individually with a grinding roller, followed by water flow to remove any loose rust. However, due to the wide range of strip widths (20 mm to 200 mm) and the fixed grinding range of the grinding roller, the bristles on the grinding roller can be unevenly worn when grinding narrow strips. Furthermore, when grinding wider strips, the grinding roller may not cover the entire strip. To ensure that the grinding roller can remove rust across the width of the strip, it is necessary to reciprocate along its axis.

[0003] The grinding roller is installed on the grinding roller seat and driven by the motor to rotate at high speed. The grinding roller seat is hoisted on the working main beam, and the working main beam is mounted on the upper beam. In order to realize the movement of the grinding roller along the width direction of the steel plate, that is, along the direction of its own axis, the working main beam moves along the upper beam through a screw nut mechanism or a linear motor to achieve the purpose of transverse movement of the grinding roller. In order to make the working main beam move smoothly along the upper beam, the working main beam and the upper beam are matched through a slider and a slide rail. In order to ensure smooth driving, lubricating oil is applied to the slide rail. However, since the water flow constantly flushes the grinding area, the space near the grinding roller is full of water vapor. The current working main beam and the upper beam are directly exposed and cannot shield water vapor. When these water vapor contacts the slide rail, it will accelerate the oxidation and gelation of the lubricating oil, resulting in a sharp increase in friction between the slide rail and the slider, and the grinding roller cannot be driven smoothly. In addition, the lubricating oil mixed with water vapor will cause corrosion between the slide rail and the slider, greatly reducing the service life of the slide rail and the slider. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a water-retaining sealing mechanism for the working main beam slide rail, which realizes preliminary shielding of water vapor by respectively arranging water retaining plates on the left and right sides of the working main beam, and prevents water vapor from entering the accommodating space from the gap between the water retaining plate and the upper beam by arranging brush strips and water retaining strips; prevents water vapor from entering the accommodating space from both ends of the working main beam by arranging a second sealing component; achieves the density of the sealed accommodating space, so that water vapor will not contact the slide rail and the slider, thereby ensuring the smooth sliding of the working main beam and improving the service life of the working main beam.

[0005] The technical solution of the present invention is achieved as follows:

[0006] A water-retaining sealing mechanism for a working main beam slide rail, wherein the working main beam is slidably arranged on an upper beam, a slider is provided on the bottom surface of the working main beam, and a slide rail is provided on the top surface of the upper beam that is compatible with the slider, and the sealing mechanism includes water-retaining plates symmetrically arranged on the left and right sides of a support beam, the working main beam, the two water-retaining plates and the top surface of the upper beam form an accommodating space, the slider and the slide rail are located in the accommodating space, a gap is provided between the bottom surface of the water-retaining plate and the top surface of the upper beam, and the working main beam and the front and rear ends of the upper beam have openings, and the water-retaining sealing mechanism also includes a first sealing component for sealing the gap and a second sealing component for sealing the opening.

[0007] In this solution, a gap is formed between the water baffles and the upper beam on the left and right sides of the working main beam to prevent water vapor from directly contacting the lubricating oil on the slide rails and sliders. By setting a first sealing component, the gap is shielded to prevent water vapor from entering the accommodating space through the gap. By setting a second sealing component, water vapor is prevented from entering the accommodating space through the openings at both ends of the working main beam, thereby preventing water vapor from contacting the lubricating oil on the slide rails and sliders, thereby ensuring the service life of the slide rails and sliders.

[0008] Preferably, the first sealing assembly includes a plurality of brush strips, and the plurality of brush strips are arranged on the side of the water baffle facing the grinding roller. The brush strips are arranged vertically, and the plurality of brush strips are arranged in the front-to-back direction to form a brush belt, and the brush belt is used to shield the gap. The brush belt is the same length as the working main beam. During actual operation, water vapor first contacts the brush strips. On the one hand, the brush strips effectively shield the water vapor. On the other hand, the water vapor gathers on the brush strips to form water droplets. When the working main beam moves on the upper beam, the brush strips shake and shake off the water droplets attached to their own surface. It should be noted that the water flow flushes the grinding roller, and the grinding roller rotates at high speed, causing the water flow to form water vapor. Since the water vapor content in the gap facing the grinding roller is relatively large, it is particularly easy to enter the accommodating space from the gap, so the grinding strips are arranged on the side of the water baffle facing the grinding roller.

[0009] Preferably, a mounting plate is provided on the outer side of the water retaining plate, and a plurality of the brush strips are connected to the bottom surface of the mounting plate.

[0010] Preferably, a boss is provided on the side wall of the upper beam facing the grinding roller, and the lower end surface of the brush strip abuts against the top surface of the boss. When the working main beam moves on the upper beam, the brush strip moves with the working main beam, and friction is generated between the bottom surface of the brush strip and the top surface of the boss, resulting in a large deformation of the brush strip, which easily shakes off water droplets on the brush strip. When the brush strip shakes, the water droplets flow along the brush strip onto the boss.

[0011] Preferably, the brush strip is made of nylon. Nylon has excellent heat resistance, wear resistance, and toughness, ensuring the strip's longevity. Nylon is also lightweight and has a low melt viscosity, allowing for rapid flow and easy mold filling, making it convenient for manufacturing. Furthermore, nylon has a smooth surface and a low coefficient of friction, ensuring minimal friction between the bottom surface of the brush strip and the top surface of the boss.

[0012] Preferably, two water retaining bars are provided on the top surface of the upper beam. The two water retaining bars are located on either side of the slide rail and are of equal length to the slide rail. The water retaining bars are connected to the top surface of the upper beam and located within the accommodating space. The height of the water retaining bars is greater than the width of the gap. During actual operation, a small amount of water vapor will enter the accommodating space through the brush belt. At this time, the water retaining bars further prevent the water vapor from contacting the slide rail. Specifically, after the water vapor is blocked by the water retaining bars, it will flow out of the gap along the water retaining bars, further ensuring that the water vapor will not intrude into the slide rail and slider.

[0013] Preferably, the length of the working main beam is greater than the length of the upper beam.

[0014] Preferably, the second sealing assembly includes a guide rail sealing seat and a sealing plate, the sealing seat is connected to the upper beam, and the sealing plate is connected to the end of the working main beam.

[0015] Preferably, the cross section of the guide rail sealing seat is matched with the cross section of the opening, the sealing plate is provided with a notch matched with the guide rail sealing seat, and there is a gap between the sealing plate and the guide rail sealing seat.

[0016] The principles and beneficial effects of the present invention using the above technical solution are:

[0017] 1. A receiving space is formed by the water retaining plates on the left and right sides of the support beam, the working main beam, the two water retaining plates and the top surface of the upper beam, and the slide rail and the slider are located in the receiving space, wherein water vapor can only enter the receiving space through the gap between the water retaining plates and the upper beam. Compared with the existing sliders and slide rails, the slide rails and sliders in this application are not directly exposed to the outside, which greatly reduces the possibility of water vapor directly contacting the slide rails and sliders.

[0018] 2. By arranging a brush belt on the outside of the gap, the gap can be shielded outside the accommodating space; by arranging a water retaining strip on the inside of the gap, water vapor can be prevented from contacting the slide rail and slider inside the accommodating space. The brush belt and the water retaining strip form a "double insurance" to shield the gap, thereby preventing water vapor from contacting the slide rail and slider.

[0019] 3. By setting the guide rail sealing seat and the sealing plate, the opening of the working beam can be shielded to prevent water vapor from entering the accommodating space through the opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0030] The specific implementation of the present invention is as follows:

[0031] like Figures 1 to 6As shown, the present invention provides a water-retaining sealing mechanism for a working main beam slide rail, wherein the working main beam 1 is slidably arranged on the upper beam 2, a slider 3 is provided on the bottom surface of the working main beam 1, and a slide rail 4 is provided on the top surface of the upper beam 2 to match the slider 3. The length of the working main beam 1 is greater than the length of the upper beam 2, and the sealing mechanism includes water retaining plates 5 symmetrically arranged on the left and right sides of the working main beam 1, the working main beam 1, the two water retaining plates 5 and the top surface of the upper beam 2 form an accommodating space 6, the slider 3 and the slide rail 4 are located in the accommodating space 6, and a gap 7 is formed between the bottom surface of the water retaining plate 5 and the top surface of the upper beam 2. 2 has openings 16 at the front and rear ends, and the water retaining sealing mechanism also includes a first sealing component for sealing the gap 7 and a second sealing component for sealing the opening 16. The first sealing component includes a plurality of brush strips 8, and the plurality of brush strips 8 are arranged on the side of the water retaining plate 5 facing the grinding roller 17. The brush strips 8 are vertically arranged, and the plurality of brush strips 8 are arranged along the front and rear directions to form a brush belt 9. The brush belt 9 is used to cover the gap 7. The brush belt 9 is the same length as the working main beam 1. The second sealing component includes a guide rail sealing seat 13 and a sealing plate 14. The sealing seat is connected to the upper beam 2, and the sealing plate 14 is connected to the end of the working main beam 1.

[0032] In this solution, a gap 7 is formed between the water retaining plates 5 and the upper beam 2 on the left and right sides of the working main beam 1 to prevent water vapor from directly contacting the lubricating oil on the slide rail 4 and the slider 3. By setting a first sealing component, the gap 7 is shielded to prevent water vapor from entering the accommodating space 6 from the gap 7. By setting a second sealing component, water vapor is prevented from entering the accommodating space 6 from the openings 16 at both ends of the working main beam 1, thereby preventing water vapor from contacting the lubricating oil on the slide rail 4 and the slider 3, thereby ensuring the service life of the slide rail 4 and the slider 3. During actual operation, water vapor first contacts the brush strip 8. On the one hand, the brush strip 8 effectively blocks the water vapor. On the other hand, the water vapor gathers on the brush strip 8 to form water droplets. When the working main beam 1 moves on the upper beam 2, the brush strip 8 shakes, shaking off the water droplets attached to its surface. It should be noted that water vapor refers to the tiny water droplets formed when the water flow collides with the high-speed rotating grinding. These tiny water droplets will float in the space near the grinding roller 17. It is understandable that the area near the grinding roller 17 has a high water vapor content. In this embodiment, since the water vapor content in the gap 7 on the side facing the grinding roller 17 is high, water vapor is particularly likely to enter the accommodating space 6 from the gap 7 there. Therefore, the grinding strip is arranged on the side of the water retaining plate 5 facing the grinding roller 17. By setting the length of the working main beam 1 to be greater than the length of the upper beam 2, it is ensured that the grinding strip can completely cover the gap 7 when the working main beam 1 moves. In addition, the front-to-back direction in this embodiment refers to the axial direction of the grinding roller, and the left-to-right direction refers to the direction that is in the same plane as the front-to-back direction and is perpendicular to the front-to-back direction.

[0033] like Figure 2As shown, a mounting plate 10 is provided on the outside of the water retaining plate 5, and a plurality of brush strips 8 are connected to the bottom surface of the mounting plate 10. A boss 11 is provided on the side wall of the upper beam 2 facing the grinding roller 17, and the lower end surface of the brush strip 8 is in contact with the top surface of the boss 11. When the working main beam 1 moves on the upper beam 2, the brush strip 8 moves with the working main beam 1, and friction is formed between the bottom surface of the brush strip 8 and the top surface of the boss 11, resulting in a large deformation of the brush strip 8, which makes it easy to shake off the water droplets on the brush strip 8. When the brush strip 8 shakes, the water droplets flow along the brush strip 8 to the boss 11. In this embodiment, the brush strip 8 is made of nylon material. Nylon has excellent heat resistance, wear resistance and toughness, which ensures the service life of the nylon strip; at the same time, nylon is light in weight, has a low melt viscosity, can flow quickly, is easy to fill the mold, and is convenient for production and manufacturing. In addition, the surface of nylon is smooth and has a low friction coefficient, so that the resistance when the bottom surface of the brush strip 8 rubs against the top surface of the boss 11 is small.

[0034] The cross-section of guide rail sealing seat 13 matches that of opening 16. Sealing plate 14 is provided with a notch that matches guide rail sealing seat 13, leaving a gap between them. During operation, guide rail sealing seat 13 and sealing plate 14 seal opening 16, preventing moisture from entering accommodating space 6 through opening 16. This gap prevents dry friction between sealing plate 14 and guide rail sealing seat 13 while also allowing room for the raising and lowering of working main beam 1.

[0035] like Figure 2 and Figure 4 As shown, two water retaining bars 12 are provided on the top surface of the upper beam 2. The two water retaining bars 12 are respectively located on both sides of the slide rail 4 and are of the same length as the slide rail 4. The water retaining bars 12 are connected to the top surface of the upper beam 2 and are located in the accommodating space 6. The height of the water retaining bars 12 is greater than the width of the gap 7. During actual operation, a small amount of water vapor will enter the accommodating space 6 through the brush belt 9. At this time, the water retaining bars 12 further prevent the water vapor from contacting the slide rail 4. Specifically, after the water vapor is blocked by the water retaining bars 12, it will flow out of the gap 7 along the water retaining bars 12, further ensuring that the water vapor will not invade the slide rail 4 and the slider 3. In addition, since the water vapor content in the gap 7 on the side away from the grinding roller 17 is low, the gap 7 there can be shielded from water vapor entering the accommodating space 6 by the water retaining bars 12 alone. In production, whether to set the brush bar 8 in the gap 7 on the side away from the grinding roller 17 is selected according to actual needs.

[0036] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
