Description

Technical Field

[0001] This utility model relates to the technology for recycling retired photovoltaic modules, and in particular to a multi-channel cleaning device for the aluminum frame of photovoltaic modules. Background Technology

[0002] Aluminum frames constitute a significant proportion of the total weight and cost of photovoltaic (PV) modules. Aluminum alloy frames have a high recyclability rate; through sorting, refining, and processing, they can be reused in the production of new aluminum frames, significantly reducing production costs and minimizing primary ore mining. For double-glass PV modules in retirement, the aluminum frames are typically removed mechanically or manually, leaving a large amount of laminated double-glass glass residue in the frame slots, which is extremely difficult to clean. If this impurity glass flows into the aluminum alloy recycling furnace, it will severely impact the quality of the recycled aluminum alloy.

[0003] Traditional manual cleaning of double-glass laminates in decommissioned photovoltaic modules is obviously unreasonable, and there is no applicable mechanical equipment in the current technology. Therefore, developing a method that can quickly, efficiently, and safely remove glass debris from the aluminum alloy side grooves of decommissioned photovoltaic modules is the key to solving the problem of aluminum alloy recycling purity. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide a multi-channel cleaning device for aluminum frames of photovoltaic modules. It features continuous operation, rapid positioning, multiple cutting channels running in parallel, simple operation, and thorough cleaning of glass debris.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a multi-channel cleaning device for aluminum frames of photovoltaic modules, including a frame with a working platform, characterized in that the working platform of the frame is divided into two areas: a feeding area and a discharging area, with the cutting shaft assembly as the reference; a number of positioning pressure rollers are provided in the feeding area, and a conveying assembly corresponding to the positioning pressure rollers is provided in the discharging area, the conveying assembly including a conveyor belt and a pressing roller that cooperates with the conveyor belt; the cutting shaft assembly is provided with a number of cutting blades corresponding to the number of positioning pressure rollers and the conveying assembly.

[0006] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, the cutting shaft assembly is driven by a main motor; the cutting shaft assembly includes a main shaft, which is positioned on the frame by a bearing seat, and one end of the main shaft is provided with a pulley, which is connected to the main motor by a belt.

[0007] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, the conveying component is driven by a conveying motor; the conveying component includes a horizontally arranged driving wheel and a driven wheel, and a conveyor belt perpendicular to the frame working platform is provided between the driving wheel and the driven wheel. The clamping wheel is located on one side of the conveyor belt, and the axle of the clamping wheel is parallel to the driving wheel and the driven wheel.

[0008] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, the distance between the pressure roller and the conveyor belt is adjustable.

[0009] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, the axle of the drive wheel in the conveying component passes through the frame working platform and is driven by the conveying motor through a bevel gear set.

[0010] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, a dust cover is provided above the cutting shaft assembly, and a suction pipe is provided on the dust cover.

[0011] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, each set of positioning rollers consists of several horizontally arranged rollers, including multiple rollers located on the same straight line and a single roller that maintains a width distance from the multiple rollers, and the position of the single roller on the machine frame working platform is adjustable.

[0012] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, a number of pressure rollers are provided corresponding to the length of the conveyor belt in the conveying assembly, and the pressure rollers are provided with springs that act in the direction of the conveyor belt.

[0013] In the aforementioned multi-channel cleaning device for aluminum frames of photovoltaic modules, preferably, a waste collection trough is provided below the cutting shaft assembly.

[0014] Since the aluminum alloy frames in retired photovoltaic modules are from the same series of products and have the same basic dimensions of width or length, this technical solution takes advantage of this feature by arranging several cutting channels on the rack work platform, so that the aluminum alloy frame strips disassembled in the same batch can be slotted and broken glass cut on these cutting channels.

[0015] This device forms the travel path of the aluminum alloy frame strip being processed through the orderly arrangement of positioning pressure rollers and conveying components. The positioning pressure rollers on one side of the feeding area can fix the aluminum alloy frame strip, ensuring stable alignment of the slot with the cutting blade; the conveyor belt of the conveying component can move the aluminum alloy frame strip on its own, and maintain the stability of the aluminum alloy frame strip under the action of the pressure rollers, avoiding shaking and displacement during the cutting process, ensuring smooth completion of the cutting operation, and quickly removing it from the working area.

[0016] The number of cutting blades on the cutting shaft assembly of this device can be set according to the workload of each operator, ensuring both equipment utilization efficiency and operator safety.

[0017] Furthermore, the distance between the pressure rollers and the conveyor belt is adjustable, accommodating aluminum alloy frames of varying widths. A dust cover is installed above the cutting shaft assembly to shield against dust or debris generated during cutting, preventing injury. The dust is also collected and recycled, and connected to an external vacuum cleaner via a suction pipe to reduce environmental pollution.

[0018] Compared with the prior art, the advantages of this utility model are: multiple cutting channels on the same working platform can operate simultaneously and continuously, resulting in high work efficiency; the aluminum alloy edge strips to be processed can be quickly positioned and automatically cut; the operator only needs to work on one side of the feeding area, making the operation simple; and dust and glass debris are collected and processed uniformly.

Detailed Implementation

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 As shown in the figure, this embodiment of a photovoltaic module aluminum frame multi-channel cleaning device is provided with a frame 1 with a working platform. The working platform of the frame is divided into two areas with the cutting shaft assembly 2 as the reference: the front and rear areas, namely the feeding area 101 and the discharge area 102.

[0028] Three sets of positioning pressure rollers 3 are provided in the feeding area 101, such as Figure 4As shown, each set of positioning rollers 3 consists of 3 horizontally arranged rollers, including 2 rollers arranged on the same straight line, i.e. the direction of movement of the aluminum alloy edge strip, and a single roller that maintains a width distance from the 2 rollers. The distance between the single roller and the straight line where the 2 rollers are located is the width of the aluminum alloy edge strip to be processed. The position of the single roller on the working platform of the frame 1 is adjustable.

[0029] The discharge area 102 is equipped with conveyor assemblies corresponding to the three sets of positioning pressure rollers, forming three cutting channels. The conveyor assemblies include a conveyor belt 4 and pressure rollers 5 that cooperate with the conveyor belt 4. The cutting shaft assembly 2 is equipped with three cutting blades 203 corresponding to the three sets of positioning pressure rollers and the conveyor assemblies, such as... Figure 6 As shown.

[0030] Cutting shaft assembly 2 is driven by main motor 10, see [link / reference] Figure 5 The cutting axis assembly 2 includes a spindle 202, see also Figure 6 The main shaft 202 is positioned on the frame 1 by two bearing seats 11. One end of the main shaft 202 is provided with a pulley 201, which is connected to the pulley on the main motor 10 by a V-belt.

[0031] The conveying assembly is driven by a conveyor motor 8. The conveying assembly includes a driving wheel and a driven wheel horizontally arranged on the working platform of the frame 1. A conveyor belt 4, perpendicular to the working platform of the frame 1, is provided between the driving wheel and the driven wheel. A pressure wheel 5 is located on one side of the conveyor belt, and the axle of the pressure wheel 5 is arranged parallel to the driving wheel and the driven wheel. The axle of the driving wheel in the conveying assembly passes through the working platform of the frame 1 and is driven by the conveyor motor 8 through a bevel gear set. The bevel gear set is the conveying transmission assembly 9, which includes a horizontally arranged drive shaft with three bevel gears corresponding to the axle of the driving wheel. A bevel gear is also provided at the bottom of the driving wheel axle. The transmission direction is changed through the bevel gear transmission. One end of the drive shaft is also driven by the conveyor motor 8 through the bevel gear set.

[0032] Furthermore, the distance between the pressure roller 5 and the conveyor belt 4 is adjustable, and the pressure roller 5 is equipped with a spring that acts in the direction of the conveyor belt 4. Generally, two pressure rollers 5 are provided corresponding to the length of the conveyor belt 4 in the conveying assembly, and the positions of the two pressure rollers 5 are basically corresponding to the positions of the driving roller and the driven roller.

[0033] In addition, a dust cover 6 is provided above the cutting shaft assembly 2, and a suction pipe 7 is provided on the dust cover 6, which is connected to a dust collection device. A waste collection tank is provided in the frame 1 below the cutting shaft assembly 2.

[0034] Working principle and usage:

[0035] On one side of the feeding area 101, each set of positioning pressure rollers 3 positions the aluminum alloy edge strip to be processed on one side and pushes it towards the discharge area 102. When the broken glass in the slot on one side of the aluminum alloy edge strip comes into contact with the cutting blade on the cutting shaft assembly, the broken glass is cut. Once the glass fragments in the slot are cut, they easily fall out of the slot. The fallen broken glass is collected in the waste collection trough. The dust generated during the cutting process is sucked away by the external matching dust collection equipment through the dust suction pipe 7 inside the dust cover 6. When the aluminum alloy edge strip comes into contact with the conveyor belt 4 of the conveying assembly, due to the friction, the conveyor belt 4 and the pressure rollers jointly push the aluminum alloy edge strip towards the discharge area 102 until it is removed from the discharge area 102.

[0036] The above embodiments are illustrative of the present invention and not intended to limit the present invention. The described embodiments are merely some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
