Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a servo-controlled edge scraping device. Background Technology

[0002] A board edge scraping device is a piece of equipment used to process the edges of boards. It is mainly used to remove burrs, flash, and sharp edges from the board edges, making the edges smoother and flatter, thus improving the quality and safety of the board. The existing board edge scraping device has a very rudimentary structural design. When changing the curvature of the scraping blade, the scraping blade must be manually disassembled first, and then replaced. The entire replacement process is inefficient and inconvenient to operate. During the scraping process, some ribbon residue remains at the scraping blade, affecting the next processing. Waste material will splash onto other workstations, affecting the operation of other parts. In addition, the pressure of the existing scraping disc is achieved by compressing a spring by tightening a screw. The pressure of the disc cannot be quantified and must be judged by the operator's experience. Utility Model Content

[0014] Compared with the prior art, the present invention provides a servo-adjustable scraping device, which has the following advantages:

[0015] 1. This utility model, through the setting of an upper disc pressure adjustment component, a scraper advance / retreat disc pressure adjustment component, a scraper lifting component, an advance / retreat disc pressure adjustment component, a lower disc pressure adjustment component, a multi-blade scraper, a template, a gas spring, an air blowing block, and a first telescopic rod, allows for the following operation: When the multi-blade scraper on the upper scraping edge needs to change its curvature, the scraper lifting motor at the upper scraping edge moves upward, and the scraper advance / retreat motor controlling the advance / retreat moves backward, returning to a starting point. Then, starting from this starting point again, the scraper lifting motor is controlled to move downward, and the scraper advance / retreat motor is controlled to move forward, ultimately aligning the other cutting edge of the blade with the material, thus achieving the scraper change operation. The same principle applies to changing the curvature of the multi-blade scraper on the lower scraping edge. By setting a gas spring, when the lifting and retreat cylinder retracts, the upper multi-blade scraper and its disc are lifted by the lifting slide. A gas spring at the connection point prevents the upper scraping component from being too heavy and damaging the material, making the upper scraping action more stable. An air blowing block is also included. Compressed air is transmitted to the air blowing block via the waste discharge pipe. The compressed air is then transmitted to the scraping edge through the exhaust end of the air blowing block, causing the compressed air to blow away the waste material. The waste material is then transferred to the waste discharge pipe, and a collection container is connected to the discharge end of the waste discharge pipe, facilitating centralized collection of waste and preventing residual tape at the scraper, which could affect subsequent processing or splash onto other workstations and affect other components. A template is installed, which slides along the side of the edge banding tape to fix the tape, improving the stability between the tape and the board. Upper and lower disc pressure adjustment components are vertically connected to the mounting base via cylinders. The pressure of the front and rear disc cylinders is adjusted by a pressure regulating valve to achieve a suitable pressure on the board from the lower disc. The pressure is quantified based on the pressure gauge reading, thus solving the problem this invention aims to address. Attached Figure Description

The conveying screw is threadedly connected to the inside of the advance / retreat module 62, driving the advance / retreat module 62 to move along the guide posts, thereby realizing the horizontal advance / retreat movement of the multi-blade scraper 10.

[0031] In this embodiment of the invention, the multi-blade scraper 10 has blade curvatures of 2.5R, 2R, and 1.5R, and these blades are arranged along the length of the multi-blade scraper 10. By setting the multi-blade scraper 10 to have blade curvatures of 2.5R, 2R, and 1.5R, and by moving the multi-blade scraper 10, the different blade curvatures can be made to abut against the scraping edge of the board. This is more convenient than a conventional multi-blade scraper 10 with only one curvature, and eliminates the hassle of changing blades.

[0032] In this embodiment of the invention, the top of the rising slide 52 and the top of the pressure beam guide rail 4 are respectively installed at both ends of the fixed rod 16 in the vertical direction. A first buffer spring 19 is provided on the outside of the fixed rod 16.

By setting the first waste discharge pipe 181 and the second waste discharge pipe 182, the exhaust end of the air-blowing block 13 corresponding to the upper disc pressure regulating component 5 faces downwards. Exhaust air, corresponding to the top of the first waste discharge pipe 181, is supplied with compressed air to the inside of the first waste discharge pipe 181, which carries the waste into the first waste discharge pipe 181, so that the waste is discharged from the bottom of the first waste discharge pipe 181. The exhaust end of the air blowing block 13 corresponding to the lower disc pressure regulating component 9 exhausts air upwards, and corresponds to the bottom of the second waste discharge pipe 182. Compressed air is supplied with compressed air to the inside of the second waste discharge pipe 182, which carries the waste into the second waste discharge pipe 182, so that the waste is discharged from the top of the second waste discharge pipe 182. By fitting the collection container at the bottom of the first waste discharge pipe 181 and the top of the second waste discharge pipe 182, some ribbon may remain at the scraper, affecting the next processing, or splashing onto other workstations and affecting the operation of other components.

[0035] In use, the sheet metal is first transported to one end of the scraping device via the pressure beam guide rail 4. The sheet metal is then moved by a track and slides on the upper edge of the multi-blade scraper 10, thus scraping the surface of the sheet metal. Compressed air is transmitted to the air blowing block 13, and through the exhaust end of the air blowing block 13, the compressed air is transmitted to the scraping area, causing the compressed air to blow away the waste material. The waste material is then transferred to the waste discharge pipe 18, where it is collected by a collection bag or collection box fitted onto the discharge end of the waste discharge pipe 18 for waste recycling. When the multi-blade scraper 10 needs to be replaced... When the scraper is raised, the scraper lifting motor 71, which controls the raising and lowering of the upper scraper edge, moves upward, while the scraper forward and backward motor 61, which controls the forward and backward movement, moves backward, returning to a starting point. Then, starting from this starting point again, the scraper lifting motor 71 is lowered, and the scraper forward and backward motor 61 is moved forward, so that the other cutting edge of the blade is aligned with the board material, thus realizing the blade change operation. The same principle applies to changing the curvature of the multi-blade scraper 10 on the lower scraper edge. The pressure of the front and rear disc cylinders is adjusted by the pressure regulating valve to make the pressure of the lower disc on the board material reach a suitable state, and the adjustment is quantitative according to the reading of the pressure gauge.
