Description

Technical Field

[0001] This application relates to the field of glass processing, and in particular to a screen glass etching processing apparatus. Background Technology

[0002] In the processing of screen glass, etching is one of the key steps. To ensure the uniformity and accuracy of the etching effect, the glass needs to undergo strict cleaning and drying treatment before etching.

[0003] An existing Chinese patent (publication number: CN215314208U) describes a screen glass etching processing device, specifically relating to the glass processing field. It includes a base plate with multiple hydraulic push rods fixedly mounted on its upper part. Multiple pads overlap the upper parts of these hydraulic push rods, and connecting rods are fixedly mounted on opposite sides of the pads. A processing glass plate overlaps the upper part of each pad, and the processing glass plate and pads are arranged in an alternating layered configuration. A water collection tank is fixedly mounted on the upper part of the base plate. Multiple support columns (first type) are fixedly mounted on the upper part of the base plate, and a drying chamber is fixedly mounted on top of each support column (first type). The drying chamber contains a drying device. Multiple support columns (second type) are fixedly mounted on the upper part of the base plate, and an etching machine is fixedly mounted on top of each support column (second type). This device features automatic drying, integrating cleaning, drying, and etching. After the processing glass plate is placed, the machine operates automatically, significantly improving the device's operating efficiency.

[0004] In practice, when using a drying chamber to dry glass, traditional glass drying equipment usually uses simple heating devices, such as electric heating wires, to dry the glass. Although this method can remove moisture from the glass surface, the air humidity inside the drying chamber is high during the drying process, which can easily lead to residual moisture on the glass surface and affect the quality of subsequent etching processes. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that the high humidity in the drying chamber during the drying process easily leads to residual moisture on the glass surface, affecting the quality of subsequent etching processes. This application provides a screen glass etching processing apparatus.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A screen glass etching processing apparatus includes a cleaning chamber, a drying chamber installed at one end of the cleaning chamber, an etching platform installed at one end of the drying chamber, a conveyor belt installed inside the drying chamber, a plurality of evenly distributed electric heating rods fixed inside the drying chamber, and a circulating dehumidification mechanism provided on the drying chamber.

[0008] By adopting the above technical solution, the circulating dehumidification mechanism circulates the air in the drying chamber, allowing the heated air in the drying chamber to flow and contact the glass, thus drying the glass. At the same time, the circulating dehumidification mechanism absorbs the moisture in the circulating air, reducing the humid environment in the drying chamber. This reduces the possibility of dust from the outside air entering the drying chamber and contacting the glass, thereby improving the drying effect.

[0009] Furthermore, the circulating dehumidification mechanism includes two air ducts 2 symmetrically arranged on both sides of the drying chamber. Two air ducts 1 are fixed on the air ducts 2. A fan is fixed inside the air duct 1. The air duct 1 is connected to the air duct 2 and connected to the drying chamber. A connecting pipe is fixed between the two air ducts 2. The connecting pipe is connected to the air duct 2. Several dehumidification components are arranged inside the connecting pipe.

[0010] By adopting the above technical solution, the air in the drying chamber is circulated along the air duct 1, air duct 2 and connecting pipe by the fan. During the circulation process, the air passes through the dehumidification component, which absorbs the moisture in the air. This improves the drying effect of the glass in the drying chamber, reduces the amount of dust blown onto the glass from the outside air, and reduces the moisture in the air, further improving the drying effect.

[0011] Furthermore, the dehumidification assembly includes a support frame disposed within a connecting pipe, the support frame extending through the connecting pipe, a desiccant mesh fixed to the support frame, and the desiccant mesh filled with granular desiccant.

[0012] By adopting the above technical solution, the humid air passing through the connecting pipe comes into contact with the granular desiccant in the desiccant net bag, thereby reducing the circulating moisture and improving the drying effect.

[0013] Furthermore, two symmetrical sliding rods are fixed on the support frame, and two symmetrical sliding rails are provided on the support frame. The sliding rails are fixedly connected to the inner wall of the connecting pipe, and the sliding rods are slidably connected to the sliding rails.

[0014] By adopting the above technical solution, the sliding rod on the support frame can move along the sliding rail, thereby making it easy to pull the support frame out of the connecting pipe.

[0015] Furthermore, the desiccant mesh bag is a stainless steel wire mesh bag.

[0016] By adopting the above technical solution, the desiccant net bag is made of stainless steel wire, thereby improving the durability of the desiccant net bag.

[0017] Furthermore, the desiccant net bag has several connecting holes that penetrate the desiccant net bag.

[0018] By adopting the above technical solution, a connecting hole is opened on the desiccant mesh bag, allowing air to pass through the connecting hole, thereby improving the air passage rate through the desiccant mesh bag.

[0019] Furthermore, two air nozzles are fixed inside the drying chamber, and the two air nozzles correspond one to one with the air inlet duct.

[0020] By adopting the above technical solution, when air passes through the air nozzle, the air nozzle compresses the air, increasing the airflow velocity, thereby further improving the drying effect.

[0021] Furthermore, a sealing cover plate is fixed on the support frame, a fixing magnetic strip is fixed on one side of the sealing cover plate, and a metal strip corresponding to the fixing magnetic strip is fixed on the connecting pipe.

[0022] By adopting the above technical solution, the sealing cover plate directly contacts the connecting pipe, and then the magnetic strip fixed on the connecting pipe is attracted to the metal strip on the connecting pipe, thereby fixing the support frame and reducing the possibility of air escaping from the connecting pipe.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the glass is moved into the drying chamber for drying, a fan located in duct one on one side of the drying chamber draws air from inside the drying chamber, allowing the air to pass through duct one into duct two, and then from duct two into a connecting pipe. The humid air then passes through the desiccant mesh on the support frame and comes into contact with the granular desiccant filled in the mesh. The granular desiccant is silica gel granules. The moisture in the air is absorbed upon contact with the granular desiccant. The air then enters duct two on the other side, and from duct two into duct one. Finally, driven by a fan in duct one, the air is blown into the drying chamber. The air circulation within the drying chamber enhances the drying effect of the glass and allows the air to come into contact with the granular desiccant, reducing moisture in the air and improving the drying efficiency. When it is necessary to replace the granular desiccant in the desiccant net bag, simply pull the support frame, which will move the sliding rod along the sliding rail. The support frame, along with the desiccant net bag, will then be pulled out of the connecting pipe. After the granular desiccant is replaced, simply insert the support frame back into its original position. This achieves the goal of improving the drying effect of the glass in the drying chamber, reducing dust from the outside air from being blown onto the glass, and reducing moisture in the air, thereby further enhancing the drying effect.

[0025] 2. In this application, when the support frame needs to be removed, the sealing cover is pulled directly. The sealing cover causes the fixing magnetic strip to disengage from the metal strip on the connecting pipe. Then, the sealing cover causes the support frame to be pulled out of the connecting pipe. When the support frame is inserted into the connecting pipe, the sealing cover directly abuts against the connecting pipe. Then, the fixing magnetic strip on the connecting pipe and the metal strip on the connecting pipe are attracted together. This achieves the purpose of fixing the support frame and reducing the possibility of air escaping from the connecting pipe. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a screen glass etching processing apparatus.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A screen glass etching processing apparatus includes a cleaning chamber 1, a drying chamber 2 installed at one end of the cleaning chamber 1, an etching platform 3 installed at one end of the drying chamber 2, a conveyor belt installed inside the drying chamber 2, a number of evenly distributed electric heating rods 4 fixed inside the drying chamber 2, and a circulating dehumidification mechanism 5 provided on the drying chamber 2.

[0035] When using this glass etching processing device, the glass is sent to the cleaning chamber 1 for cleaning, and then the glass is moved to the drying chamber 2. The electric heating rod 4 in the drying chamber 2 heats the glass, and then the circulating dehumidification mechanism 5 circulates the air in the drying chamber 2, allowing the heated air in the drying chamber 2 to come into contact with the glass and dry it. At the same time, the circulating dehumidification mechanism 5 absorbs the moisture in the circulating air, reducing the humid environment in the drying chamber 2. Then the glass comes out of the drying chamber 2 and moves to the etching platform 3 for etching processing. By setting the circulating dehumidification mechanism 5 on the drying chamber 2, the air in the drying chamber 2 is circulated to dry the glass, and the moisture in the air is reduced. This reduces the possibility of dust from the outside air entering the drying chamber 2 and coming into contact with the glass, and also reduces the humid environment in the drying chamber 2, thus improving the drying effect.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The circulating dehumidification mechanism 5 includes two air ducts 52 symmetrically arranged on both sides of the drying chamber 2. Two air ducts 51 are fixed on the air ducts 52. A fan 54 is fixed inside the air ducts 51. The air ducts 51 are connected to the air ducts 52 and to the drying chamber. A connecting pipe 53 is fixed between the two air ducts 52. The connecting pipe 53 is connected to the air ducts 52. Several dehumidification components 55 are installed inside the connecting pipe 53.

[0037] In addition, the dehumidification component 55 includes a support frame 551 disposed in the connecting pipe 53, the support frame 551 passing through the connecting pipe 53, and a desiccant net bag 552 fixed on the support frame 551, the desiccant net bag 552 being filled with granular desiccant.

[0038] Furthermore, two symmetrical sliding rods 553 are fixed on the support frame 551, and two symmetrical sliding rails 554 are provided on the support frame 551. The sliding rails 554 are fixedly connected to the inner wall of the connecting pipe 53, and the sliding rods 553 are slidably connected to the sliding rails 554.

[0039] Furthermore, the desiccant mesh bag 552 is a stainless steel wire mesh bag.

[0040] Furthermore, the desiccant net bag 552 has several connecting holes that penetrate through it.

[0041] When the glass is moved into the drying chamber 2 for drying, the fan 54 in the air duct 51 on one side of the drying chamber 2 draws air from the drying chamber 2, allowing the air to pass through the air duct 51 into the air duct 52, and then from the air duct 52 into the connecting pipe 53. The humid air then passes through the desiccant net 552 on the support frame 551 and comes into contact with the granular desiccant filled in the desiccant net 552. The granular desiccant is silica gel granules. The moisture in the air is absorbed upon contact with the granular desiccant. The air then enters the air duct 52 on the other side, and from the air duct 52 into the air duct 51. Driven by the fan 54 in the air duct 51, the air blows towards the drying chamber 2, causing air circulation within the drying chamber 2 and improving the drying effect of the glass. The air is allowed to come into contact with the granular desiccant, reducing the moisture in the air and improving the drying effect. When it is necessary to replace the granular desiccant in the desiccant net bag 552, simply pull the support frame 551, which will drive the sliding rod 553 to move along the sliding rail 554. Then, the support frame 551, along with the desiccant net bag 552, will be pulled out from the connecting pipe 53. After the granular desiccant is replaced, simply insert the support frame 551 back into its original position. By utilizing the air duct 1 51, air duct 2 52, and connecting pipe 53, the air in the drying chamber 2 is circulated, allowing the air to come into contact with the granular desiccant. This improves the drying effect of the glass in the drying chamber 2, reduces the amount of dust blown onto the glass from the outside air, and reduces the moisture in the air, further improving the drying effect.

[0042] Reference Figure 1 and Figure 2 Two air nozzles 56 are fixed inside the drying chamber 2, corresponding to the air inlet duct 51. When circulating air blows into the drying chamber 2 from the air inlet duct 51, the air passes through the air nozzles 56, which have a funnel-shaped cross-section. As the air passes through the air nozzles 56, they compress the air, increasing the air velocity. By fixing the air nozzles 56 to the air outlet duct 51, the air velocity can be increased, further improving the drying effect.

[0043] Reference Figure 3 and Figure 4A sealing cover plate 57 is fixed to the support frame 551, and a fixing magnetic strip 58 is fixed to one side of the sealing cover plate 57. A metal strip corresponding to the fixing magnetic strip 58 is fixed to the connecting pipe 53. When the support frame 551 needs to be pulled out, the sealing cover plate 57 is pulled directly. The sealing cover plate 57 causes the fixing magnetic strip 58 to disengage from the metal strip on the connecting pipe 53. Then, the sealing cover plate 57 causes the support frame 551 to be pulled out of the connecting pipe 53. When the support frame 551 is inserted into the connecting pipe 53, the sealing cover plate 57 directly abuts against the connecting pipe 53. Then, the fixing magnetic strip 58 on the connecting pipe 53 attracts with the metal strip on the connecting pipe 53. By fixing the sealing cover plate 57 to the support frame 551 and fixing the fixing magnetic strip 58 to one side of the sealing cover plate 57, the support frame 551 can be fixed, and the possibility of air escaping from the connecting pipe 53 can be reduced.

[0044] Working principle: When using this glass etching processing device, the glass is sent to the cleaning chamber 1 for cleaning, and then the glass is moved to the drying chamber 2. The electric heating rod 4 in the drying chamber 2 heats the glass. The fan 54 located in the air duct 51 on one side of the drying chamber 2 draws air from the drying chamber 2, allowing the air to enter the air duct 52 through the air duct 51, and then enter the connecting pipe 53 from the air duct 52. The humid air then passes through the desiccant net 552 on the support frame 551 and comes into contact with the granular desiccant filled in the desiccant net 552. The desiccant is silica gel granules. Moisture in the air comes into contact with the desiccant and is absorbed. The air then enters the second air duct 52 on the other side, and then enters the first air duct 51 from the second air duct 52. In the first air duct 51, the fan 54 blows air into the drying chamber 2, causing the air in the drying chamber 2 to circulate and improve the drying effect of the glass. At the same time, the air comes into contact with the desiccant, reducing the moisture in the air and improving the drying effect. Then the glass comes out of the drying chamber 2 and moves to the etching platform 3 for etching.
