Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper stacker technology, and in particular to a paper stacker with anti-static function. Background Technology
[0002] A paper stacker is a device used to stack and store paper that is in use or has been used. The stacked paper is stored inside the paper stacker for easy access by personnel.
[0003] However, static electricity can be generated due to friction between the papers and the processing methods during printing. Stacking papers with static electricity can cause them to attract each other, making it difficult to separate them when needed. Furthermore, the attracting of papers may result in multiple sheets being pulled out at once when needed. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this invention is to provide a paper stacker with anti-static function, which solves the problem of paper attracting each other due to static electricity generated by itself or processing after stacking.
[0005] The technical solution of this utility model is as follows: it includes a C-shaped outer frame, a decorative panel on the side wall of the outer frame, a rectangular through slot on the top of the outer frame, a baffle strip on the inner wall of the outer frame surrounding the through slot, a limiting post on the inner side of the outer frame surrounding the baffle strip, a support plate slidably installed on the limiting post and the baffle strip, a spring sleeved on the bottom of the support plate, a protrusion on the inner wall of the outer frame near the support plate, a metal brush connected to the protrusion through a torsion shaft, a metal strip on the side of the baffle strip facing the support plate, and the metal strip and the metal brush being electrically connected and grounded together.
[0006] Furthermore, the edge of the tray is provided with an irregular skirt. The irregular part of the skirt surface is divided into grooves and protrusions. The grooves are adapted to the baffles and metal brushes, and the protrusions are provided with through holes for inserting the limiting posts, so that the tray forms a plate-like structure with a convex top. Paper can be placed through the convex part, while the skirt part is used to accommodate the baffles and metal brushes to approach the paper, ensuring that the baffles and metal brushes can contact the paper on the convex part. At the same time, the baffles can also restrict the placement of the paper.
[0007] Furthermore, the spring is always in a relaxed state, supporting the support plate near the slot at the top of the outer frame.
[0008] Furthermore, the metal brush consists of a rotating shaft and metal bristles. The radius of rotation of the metal bristles extends into the holding area of the tray, ensuring that the metal brush can contact the paper held on the surface of the tray.
[0009] Furthermore, the rotational resistance generated by the torsion shaft inside the boss on the metal brush is less than the deformation force of the metal brush bristles themselves, preventing the metal brush from rotating excessively. This ensures that the paper does not push the metal brush to rotate when passing through it, thus ensuring that the bristles of the metal brush can remain in contact with the edges of the stacked paper, thereby contacting all the paper that passes through in sequence.
[0010] Furthermore, an arc-shaped plate is provided at the edge of the groove at the top of the outer frame. The arc-shaped plate bends and extends outward from the outer frame to facilitate the user in taking the paper.
[0011] Furthermore, the elastic support force of the spring is proportional to the weight of the paper supported by the tray, so that the spring always keeps the paper placed on the tray surface flush with the outer frame surface.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses the internal space of a C-shaped outer frame to form a receiving area. In the receiving area, a tray is set by a limiting post and a spring. A platform that can be moved up and down is formed on the surface of the tray to place paper. When the paper is placed on the surface of the tray, it will contact the baffle on the inner side of the outer frame. While the baffle restricts the paper on the surface of the tray, the paper will also contact the metal strip on the surface of the baffle. Since the metal strip is grounded, the static electricity in the paper is released.
[0013] 2. This utility model also provides a grounded metal brush connected to a torsion shaft on the inner side of the outer frame. When the tray supports the paper and moves vertically, the bristles of the metal brush extending to the surface of the tray will brush over the edge of the stacked paper, ensuring that each sheet of paper can come into contact with the bristles. The metal brush is also grounded, which can guide the release of static electricity in the paper. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] like Figure 1-5 As shown, a paper stacker with anti-static function includes a C-shaped outer frame 1. An arc-shaped plate is provided on the edge of the slot 2 at the top of the outer frame 1. The arc-shaped plate bends and extends outward from the outer frame 1 to facilitate the user to pick up the paper. A decorative plate is provided on the side wall of the outer frame 1. A rectangular slot 2 is opened at the top of the outer frame 1. A baffle 3 is provided around the slot 2 on the inner wall of the outer frame 1. A limiting post 4 is provided on the inner side of the outer frame 1 around the baffle 3. A support plate 5 is slidably installed on the limiting post 4 and the baffle 3. A spring 6 is provided at the bottom of the support plate 5 and sleeved on the limiting post 4. The spring 6 is always in a relaxed state to lift the support plate 5 close to the slot 2 at the top of the outer frame 1. The elastic support force of the spring 6 is proportional to the weight of the paper supported by the support plate 5, so that the spring 6 always keeps the paper placed on the surface of the support plate 5 flush with the surface of the outer frame 1. A boss 7 is located on the inner wall of the outer frame 1 near the tray 5. The boss 7 is connected to a metal brush 8 via a torsion shaft. The tray 5 has an irregular skirt edge, the irregular portion of which consists of grooves and protrusions. The grooves accommodate the baffle 3 and the metal brush 8, while the protrusions have through holes for inserting the limiting post 4, forming a plate-like structure with a convex top on the tray 5. Paper can be placed on the convex part, while the skirt edge accommodates the baffle 3 and the metal brush 8 near the paper, ensuring contact between them. The baffle 3 also restricts the placement of the paper. The metal brush 8 consists of a shaft and a metal... The metal brush 8 is made of metal bristles. The radius of rotation of the metal bristles of the metal brush 8 extends into the holding area of the tray 5, ensuring that the metal brush 8 can contact the paper held on the surface of the tray 5. The rotational resistance generated by the torsion shaft inside the boss 7 on the metal brush 8 is less than the deformation force of the metal bristles of the metal brush 8 itself, preventing the metal brush 8 from rotating excessively. This ensures that the paper does not push the metal brush 8 to rotate when passing through it, thus ensuring that the bristles of the metal brush 8 can remain in contact with the edges of the stacked paper, so that all the paper that passes through can be contacted in sequence. A metal strip 9 is provided on the side of the baffle 3 facing the tray 5. The metal strip 9 is electrically connected to the metal brush 8 and grounded together.
[0018] Working principle of this utility model: First, the user places the paper on the surface of the tray 5. When the paper is stacked on the surface of the tray 5, the weight of the paper presses the tray 5 downward, ensuring that the top of the stacked paper is always flush with the top of the outer frame 1. As the stacked paper moves downward, the sidewalls enter the restriction area of the baffle 3 and come into contact with the baffle 3. The metal strip 9 on the surface of the baffle 3 contacts the paper and guides the release of static electricity within the paper. At the same time, as the paper moves downward with the tray 5, it comes into contact with the metal brush 8. The bristles on the surface of the metal brush 8 brush over the sidewalls of the paper, and the bristles of the metal brush 8 also guide the release of static electricity contained within the paper. This ensures that even when the sidewalls of the stacked paper are uneven and cannot contact the baffle 3, the static electricity contained within the paper can still be released. When the user removes the paper, the weight inside the tray 5 decreases, and the spring 6 lifts the tray 5 upward, causing the paper to pass through the metal brush 8 again, guiding the release of static electricity contained within the paper once more. This ensures that the static electricity within the removed paper is effectively discharged and prevents the papers from attracting each other.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
