When working, the device is placed on the side wall of the rubber band machine, and then the rubber band is sleeved on the middle of the support rod 16. At this time, the electric telescopic rod 13 can be started. With the start of the electric telescopic rod 13, the slider 14 can be driven in the slide groove The inner part of the slider 12 slides, and as the slider 14 slides, the two support rods 16 on the side walls of the slider 14 are driven to move continuously. At this time, the two support rods 16 can continuously convey the rubber band to the rubber band machine. At the same time, the distance between the two support rods 16 can be adjusted to adapt to rubber bands of different widths and sizes. When the position of the support rod 16 moves, the support rod 16 can be limited by the bellows 18 arranged above and below, and the position of the support rod 16 can be fixed by clamping the support rod 16 in the middle of the bellows 18. At the same time, the rubber band can be limited by the two baffles 17 to prevent the rubber band from being set too deep, resulting in poor conveying effect. Through the above structure, the rubber band machine can be fed continuously and can adapt to rubber bands of different sizes, reducing the situation that the rubber bands of different sizes are over-stretched when the same size of material device is used during the feeding process, thereby resulting in poor stretching effect of the finished rubber band.

[0025] like Figure 1 As shown, a water tank 2 is fixedly connected to the top of the slider 14; a water pipe 21 is connected to the top of the water tank 2; the water pipe 21 faces the top of the electric telescopic rod 13. During operation, the electric telescopic rod 13 needs to frequently push the slider 14 to slide inside the slide groove 12 to achieve the feeding effect. At this time, the long-term sliding of the slider 14 will cause certain wear. At this time, by filling the lubricating liquid in the water tank 2, when the inside of the slide groove 12 needs to be lubricated, the water pump placed in the water tank 2 can be started. At this time, as the water pump is started, the lubricating liquid in the water tank 2 will enter the inside of the water pipe 21, and then be sprayed out through the end of the water pipe 21. The sprayed lubricating liquid will enter the inside of the slide groove 12 and contact the slider 14. Through the above structure, the slider 14 can be lubricated, which reduces the wear of the slider 14 caused by the slider 14 sliding for a long time in the slide groove 12, thereby increasing the service life of the slider 14.

[0026] like Figure 5 As shown, a plurality of through holes 3 are provided at the bottom of the slide groove 12; the plurality of through holes 3 are equidistantly distributed; two first card slots 31 are provided at the bottom of the fixed block 1; the two first card slots 31 are symmetrically arranged; a first card block 32 is slidably connected inside the first card slot 31; a collecting box 33 is fixedly connected to the top of the first card block 32; the collecting box 33 is directly opposite to the plurality of through holes 3. When working, the first card block 32 is slidably installed inside the first card slot 31. At this time, with the installation of the first card block 32, the collecting box 33 is also installed to the designated position. At this time, when the lubricating liquid is sprayed out from the end of the water pipe 21, the remaining lubricating liquid will flow to the inside of the first card slot 31 through the plurality of through holes 3. Through the above structure, the unused lubricating liquid can be collected, which reduces the waste caused by the turbulence of the lubricating liquid and also reduces the waste of resources.

[0027] like Figure 3 As shown, a second slot 4 is provided on a side wall of the slider 14 close to the electric telescopic rod 13; a second block 41 is detachably installed inside the second slot 4; two scrapers 42 are fixedly connected to the bottom of the second block 41; the two scrapers 42 are symmetrically arranged; the output end of the electric telescopic rod 13 is located in the middle of the two scrapers 42. When working, the second block 41 is installed inside the second slot 4. At this time, with the installation of the second block 41, the scraper 42 is also installed to the specified position. At this time, as the electric telescopic rod 13 pushes the slider 14 to slide, the two scrapers 42 also slide. The sliding of the scraper 42 can brush the bottom of the chute 12. At this time, the waste lubricating liquid accumulated on the top of the chute 12 will enter the interior of the through hole 3 with the continuous brushing of the two sliders 14, and then enter the interior of the collecting box 33. Through the above structure, the bottom of the chute 12 can be continuously scraped and brushed, thereby reducing the lubricating liquid agglomeration caused by the accumulation of waste lubricating liquid on the top of the chute 12, which affects the sliding of the slider 14.

[0028] like Figure 4 As shown, the inner wall of the water pipe 21 is hinged with multiple groups of brushes 5; the multiple groups of brushes 5 are equidistantly distributed along the length of the water pipe 21; the end of the water pipe 21 is fixedly connected with a mesh plate 51. During operation, as the water pump inside the water tank 2 is started, the lubricating fluid inside the water tank 2 will enter the inside of the water pipe 21. At this time, due to the passage of the lubricating fluid, the multiple brushes 5 inside the water pipe 21 will be driven to swing. As the multiple brushes 5 swing, the multiple brushes 5 can continuously contact the inner wall of the water pipe 21. At the same time, when the lubricating fluid is sprayed through the mesh plate 51, it can be blocked by the mesh plate 51 and flow out from the gap of the mesh plate 51. Through the above structure, not only the inner wall of the water pipe 21 can be cleaned to reduce the blockage problem caused by the agglomeration of the lubricating fluid inside the water pipe 21, but also the lubricating fluid can be sprayed out more densely.

[0029] like Figure 1 and Figure 5 As shown, two guide plates 6 are fixedly connected to the end of the first card slot 31; the two guide plates 6 are symmetrically arranged. When working, the collection box 33 needs to be installed to the bottom of the fixed block 1. At this time, through the guidance of the two guide plates 6, the first card block 32 can be more conveniently installed inside the first card slot 31. Through the above structure, the first card block 32 can be installed more conveniently, reducing the position offset when installing the first card block 32.

[0030] like Figure 1 and Figure 3 As shown, the scraper 42 is in contact with the bottom of the chute 12 . Through the above arrangement, the scraper 42 can scrape the bottom of the chute 12 more comprehensively, thereby reducing the accumulation of lubricating liquid at the bottom of the chute 12 .

[0031] When working, the device is placed on the side wall of the rubber band machine, and then the rubber band is sleeved on the middle part of the support rod 16. At this time, the electric telescopic rod 13 can be started. With the start of the electric telescopic rod 13, the slider 14 can be driven to slide inside the slide groove 12. With the sliding of the slider 14, the two support rods 16 on the side wall of the slider 14 will be driven to move continuously. At this time, the two support rods 16 can continuously transport rubber bands to the rubber band machine. At the same time, the distance between the two support rods 16 can be adjusted to adapt to rubber bands of different widths and sizes. When the position of the support rod 16 moves, the support rod 16 can be limited by the bellows 18 arranged up and down. By clamping the support rod 16 in the middle part of the bellows 18, The position of the support rod 16 is fixed. At the same time, the rubber band can be limited by the two baffles 17 to prevent the rubber band from being set too deep, which will lead to a poor conveying effect. Since the electric telescopic rod 13 needs to push the slider 14 to slide inside the slide groove 12 frequently to achieve the feeding effect, the long-term sliding of the slider 14 will cause certain wear. At this time, by filling the lubricating liquid inside the water tank 2, when the inside of the slide groove 12 needs to be lubricated, the water pump placed inside the water tank 2 can be started. At this time, as the water pump is started, the lubricating liquid inside the water tank 2 will enter the inside of the water pipe 21, and then be sprayed out through the end of the water pipe 21. The sprayed lubricating liquid will enter the inside of the slide groove 12 and contact with the slide groove 12. The first card block 32 is slidably installed into the interior of the first card slot 31. At this time, with the installation of the first card block 32, the collection box 33 is also installed to the specified position. At this time, when the lubricating liquid is sprayed out from the end of the water pipe 21, the remaining lubricating liquid will flow to the interior of the first card slot 31 through the multiple through holes 3. The second card block 41 is installed into the interior of the second card slot 4. At this time, with the installation of the second card block 41, the scraper 42 is also installed to the specified position. At this time, as the electric telescopic rod 13 pushes the slider 14 to slide, the two scrapers 42 also slide. The sliding of the scraper 42 can scrape the bottom of the slide trough 12. At this time, the waste lubricating liquid accumulated on the top of the slide trough 12 will be removed by the two scrapers. The slider 14 continuously brushes and enters the interior of the through hole 3, and then enters the interior of the collecting box 33. As the water pump inside the water tank 2 is started, the lubricating liquid inside the water tank 2 will enter the interior of the water pipe 21. At this time, due to the passage of the lubricating liquid, the multiple brushes 5 inside the water pipe 21 will be driven to swing. As the multiple brushes 5 swing, the multiple brushes 5 can continuously contact the inner wall of the water pipe 21. At the same time, when the lubricating liquid is sprayed out through the mesh plate 51, it can be blocked by the mesh plate 51 and flow out from the gap of the mesh plate 51. The collecting box 33 needs to be installed at the bottom of the fixed block 1. At this time, through the guidance of the two guide plates 6, the first card block 32 can be more conveniently installed to the inside of the first card slot 31.
