Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment manufacturing technology, and more specifically, it relates to an automatic cleaning device for a wire mesh sintering furnace. Background Technology

[0002] The photovoltaic wire mesh sintering furnace is a key piece of equipment in photovoltaic cell production, mainly consisting of the furnace body, furnace belt, heating system, temperature control system, and conveying system. The furnace body is divided into multiple temperature zones, including a preheating zone, a sintering zone, and a cooling zone, each maintained at a specific temperature through precise temperature control. The furnace belt, mostly made of metal mesh, is responsible for transporting the cells through each temperature zone. The heating system primarily uses infrared lamps or heating tubes to provide the high temperatures required for sintering. In photovoltaic cell production, the accumulation of organic residue on the furnace belt surface can affect sintering quality and increase maintenance costs, generally requiring the use of cleaning equipment to clean the furnace belt.

[0003] The existing application number is CN201620042977.4. This utility model discloses a cleaning device for the furnace belt of a screen printing sintering furnace. It includes: a lifting bracket; and a cleaning component, which is installed on a moving part of the lifting bracket. When the moving part of the lifting bracket is in position, the cleaning component can contact the surface of the furnace belt to clean it and rolls with the furnace belt during operation. This utility model can clean the furnace belt during its operation, thus avoiding the difficulties, time-consuming nature, and high costs associated with furnace belt cleaning.

[0004] Based on the above, in the existing method of cleaning the furnace belt, the debris removed is generally collected in a temporary storage box. Workers regularly clean the debris in the temporary storage box. Since the temporary storage box is generally directly slidably connected to the bottom of the cleaning device, it is easy for workers to take out the temporary storage box. Once the sintering furnace is in operation, if workers operate the temporary storage box, the residual heat in the temporary storage box can easily burn the workers, which poses a certain safety hazard. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic cleaning device for wire mesh sintering furnaces. This solves the problem that in existing furnace belt cleaning methods, the removed debris is typically collected in a temporary storage box. Workers periodically clean the storage box, which is usually directly slidably connected to the bottom of the cleaning device, making it easy for workers to remove. However, when the sintering furnace is in operation, the residual heat inside the storage box can easily burn workers, posing a safety hazard.

[0006] The purpose and effectiveness of this utility model's automatic cleaning device for wire mesh sintering furnace are achieved through the following specific technical means:

[0007] An automatic cleaning device for a wire mesh sintering furnace includes a cleaning box, cleaning ports, a lower cleaning motor, a cleaning storage box, a lower cleaning drive roller, a cleaning drive mechanism, and a cleaning protection mechanism. The cleaning box is a box-shaped structure made of high-temperature resistant material, and an insulation layer is provided inside the cleaning box.

The cleaning storage box is slidably connected to the lower inside of the cleaning box.

[0009] Furthermore, the cleaning drive mechanism also includes: an upper cleaning roller, an upper cleaning motor, and a lower cleaning brush; the upper cleaning roller is rotatably connected to the inner side of two sets of cleaning adjustment sliders, and a cleaning brush structure is fixedly connected to the outer periphery of the upper cleaning roller, the cleaning brush of the upper cleaning roller being a high-temperature resistant fiber brush structure; the upper cleaning motor is fixedly connected to the right side of the right set of cleaning adjustment sliders, and the output shaft of the upper cleaning motor is coaxially fixedly connected to the upper cleaning roller; multiple sets of lower cleaning brushes are provided, each set being a circular high-temperature resistant brush structure, and the multiple sets of lower cleaning brushes are respectively fixedly connected to the outer periphery of the lower cleaning drive roller by bolts.

[0010] Furthermore, the cleaning drive mechanism also includes a preheating component; two sets of preheating components are provided, both sets of preheating components are electric heating plate structures, and the two sets of preheating components are respectively fixedly connected to the upper and lower sides of the inner front of the cleaning box.

[0011] Furthermore, the cleaning and protection mechanism includes: a protective drive gear, a protective limiting member, and a protective drive rack; the protective drive gear is rotatably connected to the right side of the cleaning box, and the output shaft of the lower cleaning motor is connected to the protective drive gear via a belt; the protective limiting member is fixedly connected to the right side of the cleaning box; the protective drive rack is slidably connected to the inner side of the protective limiting member, and the protective drive rack meshes with the protective drive gear.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a cleaning drive mechanism. The preheating component heats the furnace belt, softening impurities on its surface. The lower cleaning motor then drives the lower cleaning drive roller, which in turn rotates the lower cleaning brush, cleaning the lower end face of the furnace belt. The multiple lower cleaning brushes prevent the brushes from pressing against the furnace belt ejector pins. Simultaneously, the upper cleaning motor drives the upper cleaning roller, cleaning the upper end face of the furnace belt. A cleaning monitoring component monitors the pressure of the upper cleaning roller during cleaning and controls the cleaning extrusion component. The push rod of the cleaning extrusion component moves up and down, causing the cleaning adjustment slider to move up and down, thus achieving timely adjustment of the cleaning pressure.

[0015] This invention, through the setting of a cleaning protection mechanism, uses the output shaft of the lower cleaning motor to drive the protective drive gear to rotate. The rotation of the protective drive gear causes the protective drive rack to move downward, thus limiting the cleaning temporary storage box and preventing workers from taking it out during cleaning. This protects workers and improves the safety of the entire cleaning device. Attached Figure Description
