Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, specifically a self-cleaning structure for a screw machine's screw dropping channel. Background Technology

[0002] In modern industrial production, screw-feeding machines are widely used as efficient screw assembly tools. The screw drop channel of a screw-feeding machine is a key component ensuring the accurate delivery of screws to the tightening position. However, in actual use, dust, iron filings, oil, screw debris, and other impurities easily accumulate inside the drop channel. The presence of these impurities not only affects the smooth sliding of screws within the channel, leading to jamming and blockages, reducing the efficiency and stability of the screw-feeding machine, but may also scratch the screw surface due to friction between the impurities and the screw, affecting the assembly quality. Traditional methods of cleaning the drop channel often require regular manual disassembly and cleaning, which is not only costly in terms of manpower and time, but also causes the channel connections to loosen due to frequent disassembly, affecting the overall performance of the screw-feeding machine. Therefore, we propose a self-cleaning structure for the screw drop channel of a screw-feeding machine to solve the above-mentioned technical problems. Utility Model Content

[0025] Please see Figure 1-6A self-cleaning structure for a screw-feeding channel of a screw-feeding machine includes a screw-feeding channel 1. A guide rail 6 is fixedly installed on the outer wall of the side of the screw-feeding channel 1. A DC motor 7 is fixedly connected to the top of the guide rail 6. A lead screw 8 is connected to the output end of the DC motor 7. The lead screw 8 is rotatably installed inside the guide rail 6 and has a moving block 9 threadedly connected to its outer wall. A connecting plate 10 is fixedly connected to the outer wall of the moving block 9. A rotating cleaning structure is connected to the connecting plate 10. A collecting structure is connected below the rotating cleaning structure. The rotating cleaning structure includes a vertical plate 2 fixedly installed on the bottom surface of the output end of the moving structure. The vertical plates 2 are symmetrically arranged, and their opposite faces are fixedly connected by a rotating shaft. A connecting rod 3 is rotatably sleeved on the outer wall of the rotating shaft. A shaft 4 is fixedly installed on the outer walls of the two sides of the end of the connecting rod 3 away from the vertical plate 2. A brush 5 is attached, with a diameter equal to that of the nail drop channel 1. A DC motor 7 drives a connecting plate 10 to rotate the cleaning structure, which moves up and down within the nail drop channel 1. This removes oil, dust, iron filings, and other impurities from the inner wall of the nail drop channel 1. The removed impurities are then collected by a collection structure at the bottom, achieving a cleaning effect. This solves the problems of nail jamming, blockage, and screw damage caused by impurities in existing technologies, replacing manual cleaning and saving time and effort. At the same time, a nozzle 11 is set on the front of the nail drop channel 1, which can blow air while the brush 5 is cleaning, further improving the cleaning effect. The nozzle 11 can also blow the screw away from the slide 12 during normal nail dropping, preventing the screw from falling out of the nail drop channel 1 from the slide 12.

[0026] For further details, please refer to Figure 1 and Figure 4 The nail-dropping channel 1 has nozzles 11 arranged linearly from top to bottom on its front side. The nozzles 11 are supplied with air by an externally connected air pump to blow air into the interior of the nail-dropping channel 1. This structure is a mature existing technology and will not be described in detail here. The nozzles 11 penetrate the front side of the nail-dropping channel 1, and their front ends are parallel to the inner wall of the nail-dropping channel 1. This arrangement prevents the brush 5 from interfering with the nozzles 11 when moving inside the nail-dropping channel 1. In this invention, the nozzles 11 serve two purposes: firstly, to clean the interior of the nail-dropping channel 1 using the rotating cleaning structure. During cleaning, the inner wall of the nail drop channel 1 and the surface of the brush 5 are blown off to remove impurities, which can further improve the cleaning effect. Secondly, when the screw drops normally in the nail drop channel 1, the screw is blown away from the slide groove 12. This can prevent the screw from falling out of the nail drop channel 1 through the slide groove 12. The slide groove 12 through the front of the nail drop channel 1 is used to allow the connecting rod 3 to drive the rotating cleaning structure to move up and down inside the nail drop channel 1 for cleaning. The width of the slide groove 12 is equal to the width of the connecting rod 3.

[0027] For further information, please refer to [link / reference]. Figure 5, the connecting plate 10 is in a "C" shape, and there is a gap between the back surface of the connecting plate 10 and the front surface of the nail dropping channel 1 that can accommodate the nozzle 11 to pass through. This setting can prevent the nozzle 11 from causing movement interference to the connecting plate 10 when the moving block 9 drives the connecting plate 10 to move up and down, thus affecting the movement of the rotating cleaning structure.

[0028] Furthermore, please refer to Figures 5-6 , the vertical plate 2 and the outer walls on both sides of the connecting rod 3 are both provided with the same thread grooves 13. The thread grooves 13 are used for positioning after the brush 5 rotates. The two ends of the rotating shaft are fixedly connected with positioning blocks 14. The positioning blocks 14 are connected to the thread grooves 13 on the outer wall of the connecting rod 3 through bolts 15. During cleaning, loosen the bolt 15, rotate the brush 5 to directly below the nail dropping channel 1, and then pass the bolt 15 through the positioning block 14 and lock it inside the thread groove 13 on the outer wall of the connecting rod 3, then the brush 5 can be positioned for cleaning. After the cleaning is completed, loosen the bolt 15 again, rotate the brush 5 to above the nail dropping channel 1, and then pass the bolt 15 through the positioning block 14 and lock it in the thread groove 13 on the side surface of the vertical plate 2, then the position of the brush 5 can be fixed to avoid affecting the normal nail dropping of the nail dropping channel 1. The thread grooves 13 on the outer walls of the vertical plate 2 and the connecting rod 3 are distributed around the rotating shaft. This setting can perform positioning when the brush 5 rotates.

[0029] Furthermore, please refer to Figure 1 and Figure 3 , the collection structure includes a long rod 16 fixedly installed on the bottom surface of the connecting rod 3. The bottom end of the long rod 16 is fixedly connected with a collection box 17. The collection box 17 rotates with the brush 5. When the brush 5 rotates to directly below the nail dropping channel 1, the collection box 17 immediately rotates to directly below the nail dropping channel 1. When the upper brush 5 cleans the inner wall of the nail dropping channel 1, the impurities and debris cleaned down can fall into the collection box 17 for collection and processing. The top surface area of the collection box 17 is set to be equal to the inner area of the nail dropping channel 1, which is convenient for the collection box 17 to completely enter and exit the inside of the nail dropping channel 1, and at the same time, it will not let the impurities and debris cleaned down fall outside the nail dropping channel 1.

[0030] In use, loosen bolt 15, rotate brush 5 directly below the nail drop channel 1, then pass bolt 15 through positioning block 14 and lock it inside the threaded groove 13 on the outer wall of connecting rod 3. Start DC motor 7, screw 8 rotates inside guide rail 6, driving moving block 9 connected by thread on outer wall to move upward. Connecting plate drives vertical plate 2 to move upward with moving block 9, thereby driving connecting rod 3 and brush to move upward in nail drop channel 1 to clean the inside of nail drop channel 1. At the same time, air pump output provides air source for nozzle to blow and clean the inside of nail drop channel 1. Collection box 17, which rotates with brush 5, collects the cleaned impurities and debris below. After cleaning, loosen bolt 15 again, rotate brush 5 above nail drop channel 1, and then pass bolt 15 through positioning block 14 and lock it inside the threaded groove 13 on the side of vertical plate 2. This fixes brush 5 above nail drop channel 1 and cleans out impurities and debris in collection box 17, completing the entire cleaning process.

[0031] 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.
