Description

Technical Field

[0001] The invention relates to a post-processing device for glass processing, in particular to a glass cleaning machine with air knife drying. Background Art

[0002] Glass cleaning machine is a common post-processing equipment in glass plate processing. It uses a combination of spraying and airflow to clean the dust on the glass plate, the powder produced after edge grinding, etc. during the transportation of the glass plate, and then blows the glass plate dry.

[0003] Chinese patent document CN221403830U discloses a drying air knife for a glass cleaning machine, which uses a blower to input air flow through an air inlet pipe into an air knife tube through a hose, so as to transport the air flow to the surface of the glass plate, so that the surface of the glass plate becomes dry. However, the above-mentioned drying air knife has two major technical defects. First, the air knife tube is only distributed on one side of the glass to be cleaned, and it cannot blow air to dry the back of the glass. When the back of the glass plate is stained with liquid, it cannot achieve the effect of drying the glass plate as a whole. Second, the blower transports the air flow through the hose. Since the hose has the characteristics of bending due to its own weight or force, the air flow output by the blower will generate turbulence due to continuous impact on the inner wall of the hose. In addition to increasing the wind resistance during air flow transportation, the turbulence will also cause vibration in the transportation pipeline, affecting the stability of the air duct operation and the drying effect. Summary of the invention

[0004] In order to solve the technical defects in the existing glass washing machines, the present invention provides a glass washing machine with air knife drying which has strong stability, excellent drying effect, energy saving and environmental protection.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention provides a glass cleaning machine with air knife drying, which mainly includes a frame, a conveying assembly and an air knife assembly. The conveying assembly is arranged on the frame, and can be used for conveying glass plates on the conveying assembly. The air knife assembly is also arranged on the frame, and its position corresponds to the position of the glass plate, so as to supply air to dry the glass surface. The frame also has an air supply assembly, which is connected to the air knife assembly by a pipeline, so as to supply dry airflow to the air knife assembly when the air supply assembly is working. The air supply assembly and the air knife assembly are connected by a rigid guide pipe, so that the airflow will not cause the pipeline to shake when it flows.

[0006] The present application optimizes the above structure, and the air supply assembly includes an upper fan and a lower fan. The upper fan delivers air to the top of the glass plate, and the lower fan delivers air to the bottom of the glass plate, so that the air supply assembly can dry both sides of the glass plate.

[0007] The present application further refines the above structure, and the wind knife assembly includes an upper wind knife and a lower wind knife. The upper wind knife is fixed above the glass plate and connected to the upper fan to supply air to dry one side of the glass. The lower wind knife is fixed below the glass plate and connected to the lower fan to supply air to dry the other side of the glass.

[0008] The present application further refines the above structure, and the conveying assembly includes a conveying motor, a conveying shaft and a conveying roller. The conveying motor is fixed on the frame to provide power for the operation of the conveying shaft and the conveying roller. The conveying shaft is arranged at the side of the frame, which is connected to the conveying motor and can rotate around the axis under the drive of the conveying motor. The conveying roller is arranged in the frame and connected to the conveying shaft. The upper air knife is located above the contact point between the conveying roller and the glass plate, and the lower air knife is located below the contact point between the conveying roller and the glass plate, so as to ensure the normal conveying of the glass plate by the conveying roller when the upper air knife and the lower air knife are working.

[0009] The present application optimizes the above structure, and at least two sets of the above air supply components are installed on the frame, and are respectively located on the left and right sides of the frame. The frame also has a sensor head for detecting the edge of the glass plate.

[0010] The present application further refines the above structure, and a partition is fixedly installed in the air knife assembly. The partition divides the inner cavity of the air knife assembly into independent cavities, so as to cooperate with the setting of the air supply assembly to accurately dry the glass plate in sections.

[0011] The present application optimizes the above structure, and the wind knife assembly is fixedly installed below the air supply assembly. A recovery chamber is also provided at the bottom of the air supply assembly, which corresponds to the position of the wind knife assembly to recover the airflow overflowing from the wind knife assembly, thereby realizing the internal circulation of the airflow in the air drying rack and saving energy loss.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the glass cleaning machine of the present invention, the air supply assembly and the wind knife assembly are connected by a rigid guide tube. On the one hand, the flow of air in the rigid guide tube is very stable, and the flow of air will not be uncertain due to the softness of the tube wall and the lack of fixed constraints, which prevents the generation of turbulence in the pipeline, reduces the wind resistance of the air flow, and improves the stability and reliability of the air duct assembly. On the other hand, the air flow will not cause the tube wall to shift due to the impact of the tube wall, which ensures the stability of the pipeline setting and avoids the shaking of the pipeline due to the impact of the air flow, so that there will be no additional force at the interface between the two ends of the pipeline and the air supply assembly and the wind knife assembly, and prevents the interface from loosening due to constant shaking of the pipeline.

[0013] 2. In the glass cleaning machine of the present invention, the wind knife assembly is composed of an upper wind knife and a lower wind knife respectively located above and below the glass plate, and connected to the upper fan and the lower fan respectively. This structure can achieve instant drying of the front and back sides of the glass plate during transportation, avoiding the accumulation of cleaning liquid on the back side of the glass.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The applicant hereby emphasizes that the following embodiments are one or several examples that can realize the new technical solutions of the present utility model, obtain corresponding technical effects, and solve corresponding technical problems, but it does not mean that the protection scope of the technical solution only includes the following embodiments.

[0017] according to Figures 1 to 9As shown, the glass cleaning machine with air knife drying of the present invention mainly includes a frame 1, a transmission component and an air knife component. The frame 1 is provided with a circuit controller electrically connected to the outside world to control the action of the glass cleaning machine. The transmission component is arranged on the frame 1, and is electrically connected to the circuit controller to drive the glass plate to move and realize the conveying of the glass plate. The air knife component is also arranged on the frame 1, and is fixed together with the frame 1, and its position corresponds to the glass plate on the transmission component, so that the conveying component can supply air to dry the glass plate when conveying the glass plate. The frame 1 also has an air supply component, which is fixed together with the frame 1, and is also electrically connected to the circuit controller to output airflow to the outside when the air supply component is powered on. The air supply component and the air knife component are connected by a guide tube 5, which is a hollow tube body, and its two ends are respectively sealed and connected to the air outlet of the air supply component and the air inlet of the air knife component, so that the airflow output by the air supply component can be conveyed into the air knife component. The flow guide tube 5 is a rigid tube body, that is, when the airflow flows in the tube body, the tube body will not move due to the impact of the airflow.

[0018] In one embodiment of the present invention, the air supply assembly is composed of an upper fan 41 and a lower fan 42, which are respectively fixed on the frame 1, and are both electrically connected to the circuit controller and are both located above the transmission assembly, and the air outlets of both are fixedly connected to the guide pipe 5. The air outlet of the guide pipe 5 connected to the upper fan 41 is located above the transmission assembly, and can convey the airflow output by the upper fan 41 to the top of the glass plate; the air outlet of the guide pipe 5 connected to the lower fan 42 is located below the transmission assembly, and can convey the airflow output by the lower fan 42 to the bottom of the glass plate. The arrangement of the upper fan 41 and the lower fan 42 can divert the dry airflow and output it, so that the wind drying effect of the airflow acts on the front and back of the glass plate respectively, thereby improving the overall drying effect of the glass plate and avoiding the accumulation of the cleaning liquid on the back of the glass plate. In addition, in actual use, the output power of the upper fan 41 and the lower fan 42 can be adjusted by the circuit controller according to the amount of liquid on the front and back of the glass plate, so as to reduce energy consumption while ensuring the drying effect of the glass plate.

[0019] In another embodiment of the present invention, the wind knife assembly is composed of an upper wind knife 31 and a lower wind knife 32. The air inlet of the upper wind knife 31 is connected to the guide pipe 5 connected to the upper fan 41, and the upper wind knife 31 is installed above the conveying assembly to output the airflow output by the upper fan 41 above the glass plate. The air inlet of the lower wind knife 32 is connected to the guide pipe 5 connected to the lower fan 42, and the lower wind knife 32 is installed below the conveying assembly to output the airflow output by the lower fan 42 below the glass plate. The arrangement of the upper wind knife 31 and the lower wind knife 32 can generate linear wind flow when the upper fan 41 and the lower fan 42 are working to cover the front and back of the entire glass plate. In this embodiment, the specific structure of the upper wind knife 31 and the lower wind knife 32 can refer to the description of the wind knife in Chinese patent document CN219817315U or CN221403830U, which will not be described in detail here.

[0020] In another embodiment of the present invention, the conveying assembly includes a conveying motor 21, a conveying shaft 22 and a conveying roller 23. The conveying motor 21 is fixed on the frame 1 and is electrically connected to the circuit controller. The conveying shaft 22 is arranged at the side of the frame 1, and can be connected to the rotating shaft of the conveying motor 21 by means of a chain, a belt, etc., and rotates around the shaft under the drive of the conveying motor 21. The conveying roller 23 is evenly distributed on the frame 1, and is connected to the conveying roller 23 by a helical gear combination or a worm gear combination structure, so that it generates synchronous rotation when the conveying shaft 22 rotates, so as to realize continuous transmission of the glass plate. In this embodiment, the upper air knife 31 and the lower air knife 32 are respectively located above and below the conveying roller 23. Specifically, the upper air knife 31 is located above the contact point between the conveying roller 23 and the glass plate, and the lower air knife 32 is located below the contact point between the conveying roller 23 and the glass plate, so as to ensure that the arrangement of the upper air knife 31 and the lower air knife 32 will not hinder the transmission of the glass plate.

[0021] In one embodiment of the present invention, two sets of air supply components are arranged on the frame 1 and fixed on the frame 1 in a left-right arrangement. The frame 1 also has a sensor head 11, which is arranged above the conveying component and is electrically connected to the circuit controller. The sensor head 11 can detect the edge of the glass plate when working, so as to control the working mode of the air supply component through the circuit controller. In this embodiment, a swing rod 12 is also provided between the sensor head 11 and the frame 1. One end of the swing rod 12 is fixed to the sensor head 11, and the other end can swing around the axis between the frame 1 to adjust the trigger width of the air supply component according to actual needs.

[0022] In another embodiment of the present invention, the interior of the wind knife assembly further comprises a partition 33. The partition 33 is fixed to the wind knife assembly and can separate the inner cavity of the wind knife assembly into two independent cavities, so as to realize single-side or double-side air supply under the detection function of the induction head 11 and the control function of the circuit controller.

[0023] In one embodiment of the present invention, the wind knife assembly is fixedly installed below the air supply assembly. A recovery chamber 43 is also provided at the bottom of the air supply assembly, and the position of the recovery chamber 43 corresponds to that of the wind knife assembly, so that negative pressure is generated at the recovery chamber 43 when the wind knife assembly is working, and the airflow overflowing from the wind knife assembly is recovered.

[0024] When the glass cleaning machine of the present invention is working, the glass plate is transported by the conveying assembly. Before cleaning or at the front end of the rack feeding section, the induction head 11 is passed. When the induction head 11 senses that there is no glass plate, the circuit controller triggers unilateral drying and controls the unilateral air supply assembly to work. The upper fan 41 and the lower fan 42 respectively transport the airflow to the upper air knife 31 and the lower air knife 32 of the air knife assembly through the guide pipe 5. At this time, only one side of the cavity of the upper air knife 31 and the lower air knife 32 has the effect of airflow, which reduces the loss of the total amount of airflow and the airflow speed, so as to realize the normal operation of the glass cleaning machine in the energy-saving mode. The upper air knife 31 and the lower air knife 32 output the airflow to the front and back of the glass plate respectively, and when the upper fan 41 or the lower fan 42 is working, a negative pressure for sucking the airflow is formed below it. The negative pressure sucks the airflow overflowing from the upper air knife 31 and the lower air knife 32 back into the upper fan 41 or the lower fan 42, so as to prevent external dust from entering the air supply assembly to form an internal circulation of the airflow. When the induction head 11 senses the glass plate, the circuit controller triggers the two-way drying and controls the single-side air supply component to work. The upper fan 41 and the lower fan 42 respectively deliver the airflow to the upper air knife 31 and the lower air knife 32 of the air knife component through the guide tube 5. At this time, the cavities on both sides of the upper air knife 31 and the lower air knife 32 are affected by the airflow, that is, the air knife component works at full load. The upper air knife 31 and the lower air knife 32 output the airflow to the front and back of the glass plate respectively, and when the upper fan 41 or the lower fan 42 is working, a negative pressure for sucking the airflow is formed below it. The negative pressure sucks the airflow overflowing from the upper air knife 31 and the lower air knife 32 back into the upper fan 41 or the lower fan 42 to prevent external dust from entering the interior of the air supply component to form an internal circulation of the airflow.
