Technical Field
[0001] This utility model belongs to the field of saw blade processing technology, specifically an automatic feeding and tooth-punching machine for saw blade strip steel. Background Technology
[0002] In industries such as metal processing and woodworking, automatic strip feeding and tooth punching machines for saw blades are widely used in various saw blade manufacturing enterprises as key equipment for realizing automated saw blade production. Through automatic feeding and tooth punching functions, this equipment can quickly and efficiently process strip steel into saw blades with specific tooth shapes, greatly improving production efficiency and saw blade processing accuracy.
[0003] However, in actual production, existing automatic feeding punching machines have significant defects when processing strip steel of different thicknesses. Since the required feeding speed varies for strip steel of different thicknesses, current equipment often requires operators to spend a lot of time manually adjusting equipment parameters, or even replacing some parts, to adapt to the processing requirements of strip steel of different thicknesses. This manual adjustment method is not only inefficient and seriously affects the production progress of saw blades, but also prone to inaccurate parameter adjustments due to human error, which in turn affects the processing quality of saw blades. Therefore, this application proposes an automatic feeding punching machine for saw blade strip steel. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: an automatic feeding and punching machine for saw blade strips, comprising a processing table, a storage groove on the left side of the top of the processing table, a plurality of neatly arranged rotatable first rollers arranged in the storage groove, a support frame installed on the top of the processing table, and a liftable rotating roller arranged between the support frames, with the rotating roller located directly above the innermost first roller. Fixed plates are installed on the top of the processing table and on both sides of the storage groove, and two positioning rods are installed between the two fixed plates. Positioning components are fitted at both ends of the two positioning rods, and the positioning components are located above the first rollers. Second hydraulic rods are installed on the outer sides of the two fixed plates, and the telescopic ends of the two second hydraulic rods penetrate the fixed plates and are connected to the corresponding positioning components.
[0005] Furthermore, slots are provided on both sides of the support frame, and bearing seats are installed in both slots. The rotating shafts at both ends of the rotating roller are fixedly inserted into the two bearing seats respectively. A first motor is installed on the outside of one of the bearing seats, and the output end of the first motor is fixedly connected to the rotating shaft at one end of the rotating roller. A first hydraulic rod is installed at both ends of the top of the support frame, and the telescopic ends of the two first hydraulic rods extend into the two slots respectively and are connected to the top of the corresponding bearing seats.
[0006] Furthermore, the rod shaft at the end of each first roller is rotatably inserted into the inner wall of the storage slot, and the rod shaft at the end of each first roller away from the first motor extends to the outside of the processing table. A sprocket is installed on the rod shaft of each first roller located outside the processing table, and a chain is driven between the multiple sprockets. A second motor is installed on the side of the processing table away from the sprockets, and the output end of the second motor is fixedly connected to the rod shaft at the end of one of the first rollers.
[0007] Furthermore, the diameter of the first roller is the same as the diameter of the rotating roller, the first motor and the second motor rotate in opposite directions and at the same speed, and the top of the first roller is flush with the top of the processing table.
[0008] Furthermore, the positioning assembly includes a movable plate, a top plate, and a pressure plate. The movable plate is movably mounted on two positioning rods. The telescopic end of the second hydraulic rod is connected to the movable plate. The top plate is installed on the side of the movable plate away from the fixed plate and is located between the two positioning rods. The pressure plate is located below the top plate. Connecting rods penetrating the top plate are installed at the four corners of the top of the pressure plate. An anti-detachment plate is installed at the top of each connecting rod, and a spring is fitted on each connecting rod. The two ends of the spring are respectively connected to the top of the top plate and the bottom of the anti-detachment plate.
[0009] Furthermore, a groove is provided at the bottom of the pressure plate, and multiple rotatable second rollers are installed equidistantly in the groove, with the bottom of the second rollers extending out of the groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting an adjustable rotating roller on the processing table, and cooperating with the sprocket and chain drive to drive the rotation of multiple first rollers, not only can the steel strip of the saw blade be fed smoothly and accurately, but by adjusting the position and height of the rotating roller, the distance between the rotating roller and the first roller can be changed, thereby enabling the feeding of steel strips of different thicknesses. The positioning assembly is driven by a second hydraulic rod, which can adjust the positioning according to the strip width to improve the feeding accuracy. The elastic pressure plate in the positioning assembly is combined with the rotatable second roller, which can automatically adjust the clamping force according to the strip thickness, reduce friction, and ensure a smooth and stable feeding process, thus achieving efficient and precise saw blade production.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0013] Depend on Figure 1-5 The present invention includes a processing table 1, with a storage groove 2 on the left side of the top of the processing table 1. Multiple rotatable first rollers 3 are arranged neatly within the storage groove 2. These rotatable first rollers 3 effectively support the strip steel, reducing frictional resistance during feeding and allowing for smoother strip steel movement. A support frame 4 is installed on the top of the processing table 1, with a liftable rotating roller 7 positioned between the support frames 4. The rotating roller 7 is located directly above the innermost first roller 3. By adjusting the position and height of the rotating roller 7, the distance between it and the first roller 3 can be changed to feed strip steel of different thicknesses. Fixed plates 13 are installed on the top of the processing table 1 and on both sides of the storage groove 2. Two positioning rods 14 are installed between the two fixed plates 13, with positioning components 15 fitted at both ends of each positioning rod 14. The positioning components 15 are located above the first roller 3. Second hydraulic rods 16 are installed on the outer sides of both fixed plates 13, with their telescopic ends penetrating the fixed plates 13 and connecting to the corresponding positioning components 15.
[0014] like Figure 2 and Figure 5As shown, slots 5 are provided on both sides of the support frame 4, and bearing seats 6 are installed in both slots 5. The rotating shafts at both ends of the rotating roller 7 are fixedly inserted into the two bearing seats 6 respectively. A first motor 8 is installed on the outside of one of the bearing seats 6. The output end of the first motor 8 is fixedly connected to the rotating shaft at one end of the rotating roller 7. First hydraulic rods 9 are installed at both ends of the top of the support frame 4. The telescopic ends of the two first hydraulic rods 9 extend into the two slots 5 respectively and are connected to the top of the corresponding bearing seats 6. The bearing seats 6 in the slots 5 on both sides of the support frame 4 provide stable support for the rotating roller 7, and at the same time allow the rotating roller 7 to move up and down smoothly with the extension and retraction of the first hydraulic rods 9, ensuring the matching accuracy between the rotating roller 7 and the first roller 3.
[0015] like Figure 1 and Figure 2 As shown, the shaft at the end of each first roller 3 is rotatably inserted into the inner wall of the storage groove 2. The shaft at the end of each first roller 3 away from the first motor 8 extends to the outside of the processing table 1. A sprocket 10 is installed on the shaft of each first roller 3 located outside the processing table 1. A chain 11 is sleeved between multiple sprockets 10. A second motor 12 is installed on the side of the processing table 1 away from the sprockets 10. The output end of the second motor 12 is fixedly connected to the shaft at the end of one of the first rollers 3. Multiple first rollers 3 achieve synchronous rotation through sprockets 10 and chains 11, ensuring that the strip is subjected to uniform force in all parts, avoiding slippage or twisting of the strip during feeding, and improving feeding accuracy.
[0016] like Figure 1 and Figure 2 As shown, the diameter of the first roller 3 is the same as the diameter of the rotating roller 7, and the rotation directions of the first motor 8 and the second motor 12 are opposite to ensure that the strip is subjected to uniform force on the upper and lower surfaces during the feeding process, avoid strip deformation, and further improve feeding accuracy and stability. The first motor 8 and the second motor 12 have the same rotation speed, and the top of the first roller 3 is flush with the top of the processing table 1, so that the strip transitions smoothly during the feeding process, reducing feeding resistance and strip surface damage.
[0017] like Figure 3 and Figure 4As shown, the positioning assembly 15 includes a movable plate 151, a top plate 152, and a pressure plate 153. The movable plate 151 is movably sleeved on two positioning rods 14. The telescopic end of the second hydraulic rod 16 is connected to the movable plate 151. The top plate 152 is installed on the side of the movable plate 151 away from the fixed plate 13, and the top plate 152 is located between the two positioning rods 14. The pressure plate 153 is located below the top plate 152. Connecting rods 154 penetrating the top plate 152 are installed at the four corners of the top of the pressure plate 153. Anti-detachment devices are installed at the top of each connecting rod 154. The plate is equipped with a spring 155 on each connecting rod 154. The two ends of the spring 155 are connected to the top of the top plate 152 and the bottom of the anti-detachment plate, respectively. The pressure plate 153 is connected to the top plate 152 through the spring 155 and the connecting rod 154. The pressure plate 153 can automatically adjust the clamping force according to the thickness of the strip steel, which can ensure effective clamping of the strip steel and avoid damage to the surface of the strip steel due to excessive pressure. By adjusting the position of the two positioning components 15, the distance between the two moving plates 151 can be changed, so that the two moving plates 151 can constrain strip steel of different widths.
[0018] like Figure 4 As shown, the bottom of the pressure plate 153 is provided with a groove, and multiple rotatable second rollers 156 are installed equidistantly in the groove. The bottom of the second rollers 156 extends out of the groove to ensure full contact with the strip steel, further improving the pressing and guiding effect on the strip steel, and ensuring feeding accuracy and stability.
