Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and more specifically, to an automatic material collection device after piston sawing. Background Technology

[0002] Circular saws can be categorized by the products they process into metal circular saws and woodworking circular saws. They can also be classified by feeding method into vertical, horizontal, and scissor-type saws. Furthermore, they can be categorized by control method into manual, semi-automatic, and fully automatic saws. Specialized material racks are available to meet various needs. Circular saws are commonly used for cutting piston rods.

[0003] Existing circular saws require workers to remove the cut workpieces from the cutting table and stack them properly after cutting the pistons. This necessitates multiple workers to coordinate the process, which wastes manpower, increases labor intensity, and affects work efficiency. Therefore, we propose an automatic material collection device after piston sawing to solve these problems. Utility Model Content

[0010] A drive feed roller is installed directly below the driven feed roller, and its end is rotatably connected to the connecting frame. A driven gear is provided on the outside of the connecting frame and connected to the center of the end of the drive feed roller.

[0011] The connecting frame is rotatably connected to a swing arm via a shaft at one end near the slot. A slotted hole is provided at the top of the swing arm, and a roller is rotatably connected to the surface of the swing arm.

[0012] The lower surface of the storage rack is symmetrically equipped with guide rails corresponding to the slots. A movable block is slidably connected between the guide rails. The end of the movable block is integrally formed with a boss corresponding to the slot port. Below the boss is an ear plate that is welded to the movable block, and a shaft head that is slidably connected to the slot is welded to the ear plate.

[0013] A drive shaft with its end rotatably connected to the connecting frame is provided on one side of the swing arm. A drive gear is installed at one end of the drive shaft, and an internal gear belt is installed between the drive gear and the driven gear. A cam that abuts against the roller is installed on the drive shaft.

[0014] A tension spring is installed between the swing arm and the guide rail;

[0015] A guide frame is welded to the side wall of the connecting frame away from the cutting table, and a receiving box is connected to the end of the guide frame.

[0023] 3. Beneficial Effects

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] This solution involves placing the workpieces cut from the cutting table into a storage rack. A drive motor drives a transmission shaft to rotate in conjunction with a connecting frame. First, a cam engages with a rotating roller, causing a swing arm to oscillate. A slotted hole, in conjunction with a shaft head, pulls a movable block located inside the guide rail towards one side of the cutting table, simultaneously stretching a tension spring. When the cam's cut surface engages with the roller, the tension spring contracts, causing the movable block to move in the opposite direction. This allows a boss, in conjunction with a slot, to push the bottom workpiece out through the discharge port, where it engages with the driven and active feed rollers. The transmission shaft synchronously drives the active gear to rotate, and an internal gear belt drives the driven gear, causing the active feed roller, in conjunction with the connecting frame, to rotate, conveying the workpiece onto a guide frame. Finally, the workpiece falls into the receiving box, achieving automatic material collection, improving work efficiency and reducing manual labor intensity. Attached Figure Description

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.

[0035] Example:

[0036] Please see Figure 1-6 An automatic material receiving device after piston sawing includes a cutting table 1 and a workpiece 2 cut by the cutting table 1. A storage rack 3 is installed on one side of the cutting table 1. The storage rack 3 has a discharge port 4 with a size adapted to the workpiece 2 at the root away from the cutting table 1. A slot 16 is provided at the bottom of the storage rack 3 near the edge of the cutting table 1.

[0037] The bottom of the storage rack 3 is symmetrically welded with a connecting frame 5 in an L-shape. The top of the connecting frame 5 is provided with a guide hole 6. A movable seat 7 is installed inside the guide hole 6. A guide rod 8 extending to the top of the connecting frame 5 is installed on the top of the movable seat 7. A spring 9 is sleeved on the guide rod 8. A driven feeding roller 10 is rotatably connected between the movable seats 7.

[0038] A drive feed roller 11 is installed directly below the driven feed roller 10, and its end is rotatably connected to the connecting frame 5. A driven gear 12 is provided on the outside of the connecting frame 5 and is connected to the center of the end of the drive feed roller 11.

[0039] One end of the connecting frame 5 near the slot 16 is rotatably connected to a swing arm 13 via a shaft. A slotted hole 14 is opened at the top of the swing arm 13, and a roller 15 is rotatably connected to the surface of the swing arm 13.

[0040] The lower surface of the storage rack 3 is symmetrically equipped with guide rails 17 corresponding to the slot 16. A movable block 18 is slidably connected between the guide rails 17. The end of the movable block 18 is integrally formed with a boss 19 corresponding to the port of the slot 16. An ear plate is provided below the boss 19 and welded to the movable block 18. A shaft head 20 is welded to the ear plate and slidably connected to the slot hole 14.

[0041] A drive shaft 21 is provided on one side of the swing arm 13, which is rotatably connected to the connecting frame 5. A drive gear 23 is installed at one end of the drive shaft 21, and an internal gear belt 24 is installed between the drive gear 23 and the driven gear 12. A cam 25 that abuts against the roller 15 is installed on the drive shaft 21.

[0042] A tension spring 26 is installed between the swing arm 13 and the guide rail 17;

[0043] A guide frame 27 is welded to the side wall of the connecting frame 5 away from the cutting table 1, and a receiving box 28 is connected to the end of the guide frame 27;

[0044] One of the connecting frames 5 is equipped with a drive motor 22 whose power output end is connected to the transmission shaft 21 via a coupling;

[0045] It should be noted that, in use, the automatic material receiving device after piston sawing involves placing the workpiece cut from the cutting table 1 into the receiving rack 3. The drive motor 22 drives the transmission shaft 21 to rotate in conjunction with the connecting frame 5. First, the cam 25 rotates in contact with the roller 15, causing the swing arm 13 to swing. Then, the slotted hole 14, in conjunction with the shaft head 20, pulls the movable block 18 located inside the guide rail 17 towards one side of the cutting table 1, simultaneously stretching the tension spring 26. Once the cut surface of the cam 25 is in contact with the roller 15, the tension spring 26 retracts. The workpiece 2 is pushed out through the discharge port 4 by the boss 19 and the slot 16, and then put into contact with the driven feed roller 10 and the active feed roller 11. The drive gear 23 is driven to rotate synchronously by the transmission shaft 21, and the driven gear 12 is driven by the internal tooth belt 24, so that the active feed roller 11 rotates in conjunction with the connecting frame 5, and the workpiece 2 is conveyed to the guide frame 27 and finally falls into the receiving box 28, realizing automatic material collection, improving work efficiency and reducing manual labor intensity.

[0046] like Figure 1 As shown, one end of the spring 9 is connected to the movable seat 7, and the other end of the spring 9 is connected to the top wall of the guide hole 6.

[0047] A limit block is fixedly connected to the top of the guide rod 8;

[0048] It should be noted that the elastic force of the spring 9 is used to guide the guide rod 8 in conjunction with the connecting frame 5, thereby ensuring that the driven feed roller 10 is always in contact with the workpiece 2, so as to ensure the normal transmission of the workpiece 2.

[0049] like Figure 2 As shown, the top of the active feed roller 11 is tangent to the bottom wall of the discharge port 4, and both the active feed roller 11 and the driven feed roller 10 are in contact with the workpiece 2.

[0050] It should be noted that after the workpiece 2 is discharged through the discharge port 4, its bottom is in contact with the active feeding roller 11, which is beneficial to the conveying of the workpiece 2.

[0051] like Figure 4 As shown, the boss 19 protrudes from the slot 16;

[0052] It should be noted that the bottom workpiece 2 is pushed out through the discharge port 4 by using the boss 19 in conjunction with the slot 16.

[0053] like Figure 1 As shown, the guide frame 27 is set at an angle, and the angle between the guide frame 27 and the horizontal plane is 35°. The internal dimensions of the receiving box 28 are adapted to the dimensions of the workpiece 2.

[0054] It should be noted that automatic material collection is achieved by conveying workpiece 2 onto guide frame 27 and finally dropping it into receiving box 28.

[0055] In use: The workpiece cut from the cutting table 1 is placed in the storage rack 3. The drive motor 22 drives the transmission shaft 21 to rotate in conjunction with the connecting frame 5. First, the cam 25 is used to rotate the roller 15 and drive the swing arm 13 to swing. The slot 14 and the shaft head 20 are used to pull the movable block 18 located inside the guide rail 17 to one side of the cutting table 1. At the same time, the tension spring 26 is stretched. When the cut surface of the cam 25 is in contact with the roller 15, the tension spring 26 contracts and drives the movable block 18 to move in the opposite direction. The boss 19 and the slot 16 push the bottom workpiece 2 out through the discharge port 4 and it is in contact with the driven feed roller 10 and the active feed roller 11. The drive shaft 21 drives the active gear 23 to rotate synchronously. The internal gear belt 24 drives the driven gear 12, which makes the active feed roller 11 rotate in conjunction with the connecting frame 5, and the workpiece 2 is conveyed to the guide frame 27. Finally, it falls into the receiving box 28, realizing automatic material collection.

[0056] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
