Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a waste chip collection device for grinding the R-angle of aluminum profile strips. Background Technology

[0002] Aluminum profile processing refers to the process of transforming raw materials such as aluminum ingots and aluminum rods into industrial profiles with specific cross-sectional shapes and functional characteristics through a series of physical or chemical methods. The R-angle of the aluminum profile insertion point refers to the transition arc at the edge of the groove used to insert the thermal insulation strip in the composite processing of thermal insulation aluminum profiles. It ensures a tight fit between the thermal insulation strip and the groove of the aluminum profile. The R-angle reduces assembly stress and prevents stress concentration that could lead to cracking of the aluminum profile. However, the R-angle of the extruded aluminum profile is prone to leaving sharp edges and burrs. Direct insertion of the strip will scratch the surface of the thermal insulation strip, leading to sealing failure and reduced strength. Therefore, the R-angle needs to be polished to make the transition smooth.

[0003] In the existing process of grinding the R-angle of aluminum profile strips, a collection box with a filter screen under the processing table is used to collect the grinding waste. However, the grinding waste is prone to flying everywhere, and the filter screen is prone to clogging after long-term use. This prevents the waste from completely entering the collection box for collection, reducing the collection efficiency and effectiveness of the collection box. In addition, the flying waste can affect the working environment and affect the health of workers.

[0004] Therefore, to address the issues of grinding debris easily scattering everywhere and filter screens becoming clogged after prolonged use, preventing the debris from fully entering the collection box and reducing its collection efficiency and effectiveness, a negative pressure collection structure is implemented. This structure draws grinding debris into the dust collection device through a dust collection hood, where it is filtered by an intercepting filter. A first electric push rod drives a push plate and a rotating brush to periodically remove dust from the filter screen, ensuring continuous and stable system operation. After the debris falls into the dust collection box, a second electric push rod drives a pressure plate to compress it into blocks, thereby reducing the volume of debris and optimizing storage space. Utility Model Content

[0005] To overcome the problems in the grinding process of aluminum profiles, where a collection box with a filter screen is installed under the processing table to collect the grinding debris, the grinding debris tends to fly everywhere. After long-term use, the filter screen is prone to clogging, which prevents the debris from completely entering the collection box for collection, reducing the collection efficiency and effectiveness. In addition, the flying debris can affect the working environment and affect the health of workers.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a waste chip collection device for grinding the R-angle of aluminum profile strips, including a collection box 1 and an inner fixed chamber 7. The bottom surface of the collection box 1 is fixedly connected to an anti-slip support foot 2, the side surface of the collection box 1 is rotatably connected to a sealed box door 3, the top surface of the collection box 1 is fixedly connected to a processing table 4, the top surface of the processing table 4 is provided with a filter screen plate 5, the bottom surface of the processing table 4 is fixedly connected to a dust collection cover 6, and the inner fixed chamber 7 is fixedly connected to the inner wall of the collection box 1 and is located at the top of the inner wall of the collection box 1.

[0024] Anti-slip support feet 2 are symmetrically and alternately distributed at the four corners of the bottom surface of the collection box 1. The dust collection hood 6 is set directly below the filter screen plate 5. The bottom surface of the dust collection hood 6 is connected to the top surface of the collection box 1. The staggered anti-slip support feet 2 enhance the stability of the equipment and prevent the device from shifting due to grinding vibration. The aluminum profile is ground on the processing table 4. The waste generated by grinding enters the collection box 1 through the airflow channel formed by the filter screen plate 5 and the dust collection hood 6. The first handle 703 and the second handle 707 are abutted by the sealed box door 3 locked with the collection box 1 to prevent the filter screen 702 and the dust collection box 705 from sliding.

[0025] An exhaust chamber 101 is fixedly connected to the side of the collection box 1 near the dust collection hood 6. A fan 102 is fixedly installed on the inner wall of the exhaust chamber 101. An exhaust protective net 103 is connected to the side of the exhaust chamber 101. An air guide chamber 104 is fixedly connected to the bottom surface of the inner fixed chamber 7 near the dust collection hood 6. The end of the air guide chamber 104 is fixedly connected to the inner wall of the collection box 1. The air guide chamber 104 and the exhaust chamber 101 are interconnected. By starting the fan 102, a negative pressure airflow is formed in the air guide chamber 104 and the exhaust chamber 101. After the waste debris is sucked into the collection box 1 through the dust collection hood 6, it is filtered and intercepted by the interception filter 702 on the air guide chamber 104. The filtered air is discharged outside the device through the exhaust protective net 103. The exhaust protective net 103 can prevent foreign objects from entering the exhaust chamber 101 and damaging the fan 102.

[0026] The inner fixed chamber 7 has a guide groove 701 at one end near the dust collection hood 6. An interception filter 702 is slidably connected to the inner wall of the guide groove 701. A first handle 703 is fixedly connected to the side of the interception filter 702. The first handle 703 fits against the inner side of the sealed door 3. The first handle 703 facilitates the quick pulling of the interception filter 702 within the guide groove 701 for replacement. The interception filter 702 can filter and intercept the collected waste.

[0027] A limiting plate 704 is fixedly connected to the bottom surface of the inner fixed chamber 7 away from the guide slide 701. The limiting plates 704 are evenly distributed on the bottom surface of the inner fixed chamber 7. A dust collection box 705 is slidably connected to the inner wall of the collection box 1. The dust collection box 705 is set on the bottom surface of the inner fixed chamber 7. A limiting groove 706 is opened on the top surface of the dust collection box 705. The limiting plate 704 is slidably connected to the inner wall of the limiting groove 706. A second handle 707 is fixedly connected to the side of the dust collection box 705. The second handle 707 fits against the inner side of the sealed box door 3. The dust collection box 705 collects the filtered waste. The second handle 707 can be used to pull the dust collection box 705 to slide along the limiting plate 704, which facilitates the centralized processing of the collected waste.

[0028] A first electric push rod 708 is fixedly installed on the side of the collection box 1 near the intercepting filter 702. A push plate 709 is fixedly connected to the end of the first electric push rod 708. The push plate 709 is slidably connected to the inner wall of the inner fixed chamber 7. A brush plate 710 is fixedly connected to the bottom surface of the push plate 709. The brush plate 710 is in contact with the top surface of the intercepting filter 702. The push plate 709 is moved periodically by the first electric push rod 708 to push the filtered waste into the dust collection box 705 for collection. During the pushing process, the brush plate 710 can be moved on the surface of the intercepting filter 702 to remove residual aluminum powder on the surface of the intercepting filter 702 and avoid clogging that would cause wind pressure loss.

[0029] A second electric push rod 711 is fixedly installed on the top surface of one end of the dust collection box 705. The top surface of the second electric push rod 711 is fixedly installed on the bottom surface of the processing table 4. A pressure plate 712 is fixedly connected to the end of the second electric push rod 711. The pressure plate 712 is slidably connected to the inner wall of the inner fixed chamber 7. After the collected waste is pushed into the dust collection box 705, the pressure plate 712 is pushed downward by the second electric push rod 711 to compact the loose waste in the dust collection box 705 and reduce the volume occupied by the waste.

[0030] Working principle: According to Figures 1-3As shown, during the aluminum profile grinding process, the fan 102 is started to form a negative pressure airflow in the air guide chamber 104 and the exhaust chamber 101, so that the waste chips generated during grinding are sucked into the collection box 1 through the airflow channel formed by the filter screen 5 and the dust collection hood 6. The waste chips and dust are filtered and intercepted by the interception filter screen 702 on the air guide chamber 104, and the filtered air is discharged outside the device through the exhaust protection screen 103.

[0031] according to Figures 2-5 As shown, the first electric push rod 708 pushes the push plate 709 to move periodically, pushing the filtered waste debris into the dust collection box 705 for collection. During the pushing process, the brush plate 710 moves on the surface of the intercepting filter screen 702 to remove residual aluminum powder on the surface of the intercepting filter screen 702, avoiding blockage and resulting wind pressure loss. After the collected waste debris is pushed into the dust collection box 705, the second electric push rod 711 pushes the pressure plate 712 to move downward, pressing and compacting the loose waste debris in the dust collection box 705, reducing the volume occupied by the waste debris.

[0032] according to Figure 1 , Figure 3 and Figure 4 As shown, after working for a period of time, the sealed box door 3 is opened. The first handle 703 allows the intercepting filter 702 to be quickly pulled and slid in the guide slide 701 for cleaning and replacement. The second handle 707 allows the dust collection box 705 to be pulled along the limiting plate 704 for centralized processing of the collected waste.

[0033] Among them, the fan 102, the first electric push rod 708 and the second electric push rod 711 are existing technologies on the market and will not be described in detail here.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
