Description

Technical Field

[0001] This utility model belongs to the field of wire cutting technology, specifically relating to an automatic wire cutting device. Background Technology

[0002] In industries such as waste recycling, papermaking, and logistics, large quantities of goods (such as waste paper and pulp raw materials) are often bundled and packaged using wire. During recycling, these wires need to be cut and removed first.

[0003] Chinese patent CN218475935U discloses a fully automatic wire-cutting machine for small paper packages, including a workbench and a fixing component. The fixing component is fixedly installed inside the workbench and specifically consists of a PLC controller, a support rod, a clamping plate, a weight sensor, a load-bearing platform, a T-shaped top rod, a rotating shaft, a threaded groove, a screw A, and a servo motor. The servo motor is installed at the bottom of the workbench and connected to the screw A. The screw A is threaded into the threaded groove in the T-shaped top rod. The two ends of the T-shaped top rod are connected through the rotating shaft to pass through the top of both sides of the workbench and to the clamping plate. The top of the T-shaped top rod passes through the top of the workbench and connects to the bottom of the load-bearing platform on the surface where the weight sensor is installed. This allows the screw A to rotate, thereby sliding the T-shaped top rod downwards and gradually bringing the two sets of clamping plates closer together to clamp and fix the paper package for wire cutting. This effectively prevents the paper package from scattering after wire cutting, thus avoiding disruption to transportation and production.

[0004] While the aforementioned wire-cutting machine can effectively prevent paper packages from scattering after wire cutting, thus affecting transportation and production, the adjustment freedom and flexibility of the wire-cutting component are insufficient. The wire-cutting component can only achieve vertical lifting and lowering through the drive motor driving the screw, and its horizontal position is fixed. In actual production, the size of the paper package and the position of the wire binding may vary. The fixed horizontal position means that for paper packages that are particularly large or small, or where the wire position is off-center, the wire-cutting machine may not be able to accurately reach the optimal working position, reducing the equipment's versatility and automation level. Therefore, we propose an automatic wire-cutting device. Utility Model Content

[0005] To address the insufficient adjustment freedom and flexibility of the wire-cutting assembly mentioned in the background technology, which is problematic in actual production where the size of the paper package and the position of the wire binding can vary, a fixed horizontal position means that for particularly large or small paper packages, or those with wires off-center, the wire-cutting machine may not be able to accurately reach the optimal working position, reducing the equipment's versatility and automation level. This invention provides an automatic wire-cutting device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic wire shearing device, comprising a base, a fixed seat, and a movable seat, wherein a fixed seat is welded to the upper end face of the base, a movable seat is installed on the fixed seat, and sliders are installed on both sides of the movable seat, and clamping plates are installed on the sliders by bolts;

[0007] A lifting rod is installed at one end of the upper part of the movable seat. A lifting hydraulic cylinder is connected above the lifting rod. A conveying block is installed inside the lifting rod. A threaded screw passes through the conveying block. A conveying motor is fixed at one end of the threaded screw. A shearing head for cutting iron wire is fixed below the conveying block.

[0008] As a preferred embodiment of the automatic wire cutting device of this utility model, a linkage block is fixed below the slider, and an electric telescopic rod for driving the clamping plates on both sides to move towards or away from each other is connected to the inner side of the linkage block.

[0009] As a preferred embodiment of the automatic wire cutting device of this utility model, the electric telescopic rod is horizontally arranged, and the piston rods at both ends of the electric telescopic rod are fixedly connected to the linkage blocks on both sides respectively.

[0010] In a preferred embodiment of the automatic wire cutting device of this utility model, the cylinder body of the lifting hydraulic cylinder is fixedly connected to the top end of the lifting rod.

[0011] As a preferred embodiment of the automatic wire shearing device of this utility model, the shearing head is a hydraulic shear or a pneumatic shear.

[0012] As a preferred embodiment of the automatic wire cutting device of this utility model, a rack is fixed on one side below the movable seat, a transmission gear is engaged below the rack, and one end of the transmission gear is connected to a drive motor for driving its rotation.

[0013] In a preferred embodiment of the automatic wire cutting device of this utility model, the drive motor is connected to the shaft of the transmission gear through a reducer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the screw is driven by a transmission motor to move the transmission block equipped with the shear head along the horizontal X-axis, so that the shear head has the ability to be freely positioned on the horizontal plane. Regardless of the size of the paper package or whether the wire binding position is centered or off-center, the equipment can automatically and accurately move the shear head to the optimal cutting point through the control system, preventing the problem of insufficient adjustment freedom and flexibility of the wire cutting component, which reduces the versatility and automation of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0023] like Figures 1-5 As shown;

[0024] An automatic wire shearing device includes a base 1, a fixed seat 2, and a movable seat 3. The fixed seat 2 is welded to the upper surface of the base 1, and the movable seat 3 is installed on the fixed seat 2. Slider 4 is installed on both sides of the movable seat 3, and clamping plates 5 are installed on the slider 4 by bolts. A lifting rod 8 is installed at one end of the movable seat 3, and a lifting hydraulic cylinder 9 is connected above the lifting rod 8. A conveying block 11 is installed inside the lifting rod 8, and a threaded screw 12 passes through the conveying block 11. A conveying motor 13 is fixed at one end of the threaded screw 12, and a wire shearing head 10 for cutting the wire is fixed below the conveying block 11.

[0025] In this implementation plan: the screw rod 12 is driven by the transmission motor 13, which drives the transmission block 11, which is equipped with the shear head 10, to move along the horizontal X-axis, so that the shear head 10 has the ability to be freely positioned on the horizontal plane. Regardless of the size of the paper package or whether the wire binding position is centered or off-center, the equipment can automatically and accurately move the shear head 10 to the optimal cutting point through the control system.

[0026] In an optional embodiment, a linkage block 7 is fixed below the slider 4, and an electric telescopic rod 6 for driving the two clamping plates 5 to move towards or away from each other is connected inside the linkage block 7.

[0027] In this implementation scheme: the power output end of the electric telescopic rod 6 is directly applied to the linkage block 7, and the linkage block 7 drives the slider 4 and the clamping plate 5 to move, forming a very short and efficient power transmission chain. The linkage block 7, as a connecting part, ensures that a linear output action of the electric telescopic rod 6 can be simultaneously and equally converted into the opposite or backward movement of the clamping mechanisms on both sides, perfectly ensuring the synchronicity of the movement of the two clamping plates 5.

[0028] In an optional embodiment, the electric telescopic rod 6 is horizontally arranged, and the piston rods at both ends of the electric telescopic rod 6 are fixedly connected to the linkage blocks 7 on both sides.

[0029] In this implementation scheme: the piston rods at both ends of the electric telescopic rod 6 are fixedly connected to the linkage blocks 7 on both sides, forming a rigid integral frame structure. This completely eliminates the play that may exist in the hinge, ensuring that the entire clamping mechanism has extremely high rigidity and stability when clamping heavy paper packages, without any shaking, and with huge and reliable clamping force.

[0030] In an optional embodiment, the cylinder body of the lifting hydraulic cylinder 9 is fixedly connected to the top end of the lifting rod 8.

[0031] In this implementation plan: the cylinder body of the lifting hydraulic cylinder 9, i.e. the fixed part, is fixedly connected to the top of the lifting rod 8, which means that the entire hydraulic cylinder has a solid and immovable support base. The huge thrust or pull force generated by it can be strictly transmitted to the lower conveyor block 11 and the shear head 10 in the vertical direction, ensuring that the shear head 10 has a straight trajectory during the lifting process without drifting or swaying in the front, back, left or right.

[0032] In an optional embodiment, the shear head 10 is a hydraulic shear or a pneumatic shear.

[0033] In this implementation plan, hydraulic or pneumatic shears are specified. Both of these cutting tools can provide huge and stable cutting force with a small equipment size, and can easily and quickly cut various specifications of packing wire. Their efficiency is far superior to electric shears or manual tools, ensuring thoroughness and reliability of the process.

[0034] In an optional embodiment, a rack 14 is fixed to one side below the movable seat 3, and a transmission gear 15 is meshed below the rack 14. One end of the transmission gear 15 is connected to a drive motor 16 for driving its rotation, and the drive motor 16 is connected to the shaft of the transmission gear 15 through a reducer.

[0035] In this implementation scheme: the rotational motion of the drive motor 16 is precisely converted into the linear motion of the moving seat 3 and all its components through the meshing transmission of the transmission gear 15 and the rack 14. The reducer can smooth the output of the motor, making the start-up, operation and stop of the moving seat 3 more stable and reducing impact and vibration.

[0036] Working principle:

[0037] Place the paper package to be processed on the movable base 3 of this device, and activate the electric telescopic rod 6. The piston rod of the electric telescopic rod 6 extends, pushing the linkage blocks 7 on both sides to move towards each other. The linkage blocks 7 drive the slider 4 fixed above them to slide synchronously on the guide rail of the movable base 3, thereby driving the two clamping plates 5 installed on the slider 4 to move closer to each other. The clamping plates 5 clamp the paper package from both sides, completing the precise positioning and fixation of the paper package and preventing it from moving during the subsequent cutting process. This clamping action can adapt to paper packages of different widths.

[0038] After clamping and fixing, the conveyor motor 13 starts, driving the threaded screw 12 to rotate. The conveyor block 11, which is threadedly engaged with the threaded screw 12, moves horizontally along the axis of the screw. Then, the lifting hydraulic cylinder 9 is activated, pushing the piston rod inside and the lifting rod 8 connected to it to move downward, thereby driving the entire shear head 10 fixed below the conveyor block 11 to descend. The X-axis position is controlled by the conveyor motor 13, and the Z-axis height is controlled by the lifting hydraulic cylinder 9. The shear head 10 is precisely moved to the optimal cutting point directly above the outer wire of the paper package. The wire is then cut by the shear head 10. The shear head 10 integrates hydraulic shears, which can adaptively find the cutting position regardless of the size of the paper package or the position of the wire.

[0039] After the cutting is completed, the shear head 10 returns to its original position. Then, the drive motor 16 starts and drives the transmission gear 15 to rotate. Since the transmission gear 15 meshes with the rack 14 fixedly installed below the moving seat 3, the rotation of the gear will be converted into the linear motion of the moving seat 3 as a whole. The moving seat 3 and all its components, including the paper package with the cut wire, are pushed forward as a whole until the paper package is pushed to the position where it docks with the downstream conveyor belt. The clamping plate 5 is released, which makes it convenient for the subsequent process to transport the waste paper package away.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
