Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass sheet centrifugal drying technology, and in particular to a square glass sheet centrifugal drying fixture. Background Technology
[0002] After ultrasonic cleaning, 77*77*0.1mm square glass (hereinafter referred to as square glass) requires rapid removal of surface water. One method is to use a centrifugal dryer to quickly remove the water from the product surface using centrifugal force. Currently, traditional centrifugal drying fixtures typically... Figure 1 As shown, square glass panes are placed in the jaws of a fixture, which is then placed in a spin-coil centrifugal dryer. In the spin-coil centrifuge, the glass panes rise 90° as the centrifuge speed increases, using centrifugal force to remove wastewater from the product surface. However, current fixtures, while ensuring cleaning effectiveness, prioritize production efficiency, resulting in a small inter-panel spacing. During centrifugal drying, the excessively high airflow velocity between the square glass panes (narrowing effect) creates a pressure difference between the two sides of the product (Bernoulli's principle). When the pressure exceeds the product's tolerance, it breaks and shatters. Furthermore, due to the fragments, the centrifugal speed cannot be increased to a higher level, leaving some contaminants unremoved from the product surface. Summary of the Invention
[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a square glass sheet centrifugal drying fixture.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A square glass sheet centrifugal drying fixture includes two positioning clamps and two side plates. Each positioning clamp has six through holes. A cylinder is threaded into each through hole, and the two positioning clamps are connected by the six cylinders. The two side plates are welded to the cylinders on both sides. Five evenly distributed strips are formed on each positioning clamp. The bottom strip contains four symmetrical lower-side toothed racks with upward-facing locking teeth. The top strip contains two symmetrical upper-side toothed racks with inward-facing locking teeth. The two upper-side toothed racks are located outside the four lower-side toothed racks. A double-sided toothed rack is also located in the middle of the two upper-side toothed racks in the top strip, with locking teeth on both sides.
[0006] Furthermore, the fixture is made of 304 stainless steel.
[0007] Furthermore, the positioning clamp is a clamp with dimensions of 230x95x3mm; the side plate is a side plate with dimensions of 239x94x1mm.
[0008] Furthermore, the cylinder is a cylinder with a diameter of 6mm.
[0009] Furthermore, the locking teeth are Teflon locking teeth with a tooth pitch of 6mm and a tooth angle of 74°.
[0010] Furthermore, the strips are strips with dimensions of 212x4.2mm and a spacing of 14mm between each strip.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] This invention adds a baffle plate to the side of the clamp to block airflow interference from the side. At the same time, it modifies the height of the strip and the rack so that the placement height of the square glass is completely hidden inside the side plate. This makes the fragmentation only strongly related to the strength of the glass itself and the centrifugal force, which can improve the centrifugal force of the centrifuge, reduce the risk of fragmentation during the centrifugal drying process, thereby increasing the centrifugal drying speed, reducing the possibility of dirt residue, and improving the yield.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are 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. Therefore, they should not be construed as limitations on this utility model.
[0021] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] like Figure 2As shown, a square glass sheet centrifugal drying fixture includes two positioning clamps 1 and two side plates 2. The positioning clamps 1 are 230x95x3mm in size; the side plates 2 are 239x94x1mm in size. Each positioning clamp 1 has six through holes 3. A 6mm diameter cylinder 4 is threaded into each through hole 3, and the two positioning clamps 1 are connected by the six cylinders 4. The two side plates 2 are welded to the cylinders 4 on both sides. Five evenly distributed strips 5 are provided on the positioning clamps 1. The strips 5 are 212x4.2mm in size, and the distance between each strip 5 is 14mm. The top strip 5 is 12mm away from the top of the positioning clamp 1. The bottom strip 5 has two symmetrical lower half toothed racks 6, on which are inlaid upward-facing... The topmost strip 5 contains four symmetrical upper half-toothed racks 8, each inlaid with inward-facing toothed teeth 7. Two of the upper half-toothed racks 8 are located outside the four lower half-toothed racks 6. A double-sided toothed rack 9 is also located in the middle of the two upper half-toothed racks 8 within the topmost strip 5, with toothed teeth 7 inlaid on both sides. The toothed teeth 7 are Teflon toothed teeth with a tooth pitch of 6mm and a tooth angle of 74°. In use, a square glass sheet is placed at the toothed teeth 7, its sides limited and fixed by the upper half-toothed racks 8 and the double-sided toothed racks 9, and its bottom supported by the two lower half-toothed racks 6. Due to its size design, the square glass sheet is completely lower than the side plates 2, which can block airflow interference from the sides and reduce the risk of fragmentation during centrifugal drying. After cleaning and centrifugal drying, the square glass sheet can be removed for use. The fixture is reusable.
[0024] To extend its service life, the fixture is made of 304 stainless steel.
