Description

Technical Field

[0001] This utility model relates to the field of feeding devices, specifically a feeding device for a sawing machine. Background Technology

[0002] A band saw is a machine tool used for cutting materials such as metal, wood, and plastic. It mainly achieves cutting, grooving, and other processing through the reciprocating or rotating motion of a saw blade, band saw, or circular saw. Based on the cutting method and structure, band saws are mainly divided into the following categories: band saws, circular saws, and bow saws.

[0003] In the existing technology, before the saw can process materials, the materials usually need to be hoisted onto the loading rack and then manually pushed to the processing station of the saw. It has been found in use and observation that this loading method relies too much on manpower, which makes the saw processing relatively inconvenient.

[0004] Therefore, a feeding device for a saw is proposed to address the above problems. Utility Model Content

[0007] Preferably, two pairs of guide grooves are provided on the inner walls of the grooves on both sides of the frame; guide wheels are rotatably connected to the upper and lower sides of the support arm; the guide wheels and guide grooves are correspondingly arranged; through the cooperation of the guide grooves and guide wheels, when the gear and rack mesh, the support arm will slide along the grooves on the frame, and the support arm can slide in the guide grooves through the guide wheels. On the one hand, the guide grooves and guide wheels can provide additional guidance for the support arm, improving its stability during movement; on the other hand, the guide wheels can reduce the direct contact between the support arm and the grooves inside the frame, reducing the wear on the surface of the support arm.

[0009] Preferably, a gasket is installed on the surface of the push plate by bolts; by setting the gasket, the gasket can replace the push plate in long-term contact with the material, thereby transferring the wear of the original push plate surface to the gasket. Only the gasket needs to be replaced periodically to ensure the stable conveying of the material by the push plate. Here, the gasket can be modularly set, that is, it is composed of multiple sets of materials, which facilitates the replacement of local gaskets.

[0010] Preferably, the surface of the conveying roller is provided with multiple positioning plates; the cross-section of the positioning plate is V-shaped; by setting the positioning plate, when conveying tubular materials, the materials can be hoisted onto the positioning plate. Since the cross-section of the positioning plate is V-shaped, it can be ensured that the materials will not run out of the positioning plate when pushed by the push plate, thereby improving the stability of material conveying.

[0011] Preferably, a mounting base is fixedly connected to one side of the positioning plate; multiple sets of mounting holes are provided on the conveying roller; the mounting base and the mounting holes are connected by bolts; through the cooperation of the mounting base and the mounting holes, when conveying materials with large size differences, the positioning plate can be removed from the conveying roller through the mounting base and replaced with a positioning plate of the corresponding specification, thereby improving the adaptability of the positioning plate to conveying materials of different sizes.

When the motor 17 is started, it drives the gear 16 connected to the output end to rotate. The gear 16 meshes with the rack 15, causing the support arm 14 and the push plate 13 to slide along the groove on the frame 1 under the meshing action. During the process, the push plate 13 can push the material on the conveying roller 12. Since the meshing of the rack 15 and the gear 16 is a high-precision fit, the pushing distance of the push plate 13 can be freely and flexibly controlled each time the motor 17 is started. The working principle described here can be controlled by PLC programming, so it will not be described in detail. This achieves automatic feeding of the saw. Through the meshing action of the rack 15 and the gear 16, the power of the motor 17 during operation can be converted into the power of the radial movement of the push plate 13, so that the push plate 13 can automatically push the material on the conveying roller 12, improving the convenience of feeding when the saw is working.

[0025] Please see Figure 3 As shown, two pairs of guide grooves 2 are provided on the inner walls of the grooves on both sides of the frame 1; guide wheels 22 are rotatably connected to both the upper and lower sides of the support arm 14; the guide wheels 22 and the guide grooves 2 are correspondingly arranged; through the cooperation of the guide grooves 2 and the guide wheels 22, when the gear 16 meshes with the rack 15, the support arm 14 will slide along the groove on the frame 1. The support arm 14 can slide in the guide groove 2 through the guide wheels 22. On the one hand, the guide groove 2 and the guide wheels 22 can provide additional guidance for the support arm 14 and improve its stability during movement. On the other hand, the guide wheels 22 can reduce the direct contact between the support arm 14 and the inner groove of the frame 1 and reduce the wear on the surface of the support arm 14. It is worth mentioning that the cleaning work in the guide groove 2 can be carried out manually by blowing with an air gun, which can be a part of the regular maintenance work.

[0026] Please see Figure 3As shown, the cross-section of the support arm 14 is an E-shaped structure, and the gear 16 and rack 15 are located inside the support arm 14; the two ends of the support arm 14 are symmetrically fixed with bellows plates 3; the outer wall of the frame 1 is provided with a plate that is fixedly connected to the bellows plates 3; by setting the bellows plates 3, the bellows plates 3 on both sides and the support arm 14 can wrap and protect the transmission system of rack 15 and gear 16, thereby reducing the pollution effect of dust in the air in the processing environment and improving the stability of its meshing process.

[0027] Please see Figure 2 and Figure 3 As shown, a gasket 4 is bolted to the surface of the push plate 13. By setting the gasket 4, the gasket 4 can replace the push plate 13 in long-term contact with the material, thereby transferring the wear on the original surface of the push plate 13 to the gasket 4. Only the gasket 4 needs to be replaced periodically to ensure the stable conveying of the material by the push plate 13. Here, the gasket 4 can be modularly set, that is, it is composed of multiple sets of materials, which facilitates the replacement of local gaskets 4.

[0028] Please see Figure 4 and Figure 5 As shown, the surface of the conveying roller 12 is provided with multiple positioning plates 5; the cross-section of the positioning plate 5 is V-shaped; by setting the positioning plate 5, when conveying tubular materials, the materials can be hoisted onto the positioning plate 5. Since the cross-section of the positioning plate 5 is V-shaped, it can be ensured that the materials will not run out of the positioning plate 5 when pushed by the push plate 13, thereby improving the stability of material conveying.

[0029] Please see Figure 5 As shown, a mounting base 6 is fixedly connected to one side of the positioning plate 5; multiple sets of mounting holes 62 are opened on the conveying roller 12; the mounting base 6 and the mounting holes 62 are connected by bolts; through the cooperation of the mounting base 6 and the mounting holes 62, when conveying materials with large size differences, the positioning plate 5 can be removed from the conveying roller 12 through the mounting base 6 and replaced with a positioning plate 5 of the corresponding specification, thereby improving the adaptability of the positioning plate 5 to conveying materials of different sizes.

[0030] Working principle: The material to be processed is placed on the conveyor roller 12. When feeding the saw is needed, the motor 17 is started. The motor 17 drives the gear 16 connected to the output end to rotate. The gear 16 meshes with the rack 15, causing the support arm 14 and the push plate 13 to slide along the groove on the frame 1 under the meshing action. During the process, the push plate 13 can push the material on the conveyor roller 12. Since the meshing of the rack 15 and the gear 16 is a high-precision fit, the pushing distance of the push plate 13 can be freely and flexibly controlled each time the motor 17 is started. The working principle described here can be programmed by PLC. The process control is implemented, so it will not be described in detail here, to achieve automatic feeding of the saw. Through the cooperation of guide groove 2 and guide wheel 22, when gear 16 meshes with rack 15, the support arm 14 will slide along the groove on the frame 1. The support arm 14 can slide in the guide groove 2 through the guide wheel 22. On the one hand, the guide groove 2 and guide wheel 22 can provide additional guidance for the support arm 14, improving its stability during movement. On the other hand, the guide wheel 22 can reduce the direct contact between the support arm 14 and the groove inside the frame 1, reducing the wear on the surface of the support arm 14. It is worth mentioning that the cleaning work in the guide groove 2 can be done by man. The process involves blowing air through an air gun, which can be a routine maintenance task. By installing bellows plates 3, the two bellows plates 3 and support arms 14 can protect the transmission system of rack 15 and gear 16, reducing the contamination from airborne dust in the processing environment and improving the stability of the meshing process. By installing gaskets 4, which replace push plates 13 in long-term contact with the material, the wear on the surface of push plates 13 is transferred to the gaskets 4. Only periodic replacement of the gaskets 4 is needed to ensure stable material conveying by push plates 13. The gaskets 4 can be modular, consisting of multiple... The components are assembled from overlapping materials, facilitating the replacement of local gaskets 4. By setting up positioning plates 5, when conveying tubular materials, the materials can be hoisted onto the positioning plates 5. Since the positioning plates 5 have a V-shaped cross-section, it can be ensured that the materials will not run off the positioning plates 5 when pushed by the push plate 13, thus improving the stability of material conveying. Through the cooperation between the mounting base 6 and the mounting hole 62, when conveying materials with large size differences, the positioning plates 5 can be removed from the conveying rollers 12 through the mounting base 6 and replaced with positioning plates 5 of the corresponding specifications, improving the adaptability of the positioning plates 5 to conveying materials of different sizes.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
