Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, specifically to a multi-blade collaborative copper particle shearing device. Background Technology

[0002] Pure copper granules are widely used in PCB electroplating, steel cord plating, and electronic composite materials due to their high chemical purity and low impurity content. Generally, the processing of pure copper granules requires unwinding, straightening, and length cutting. Traditional shearing equipment mostly uses single-line unwinding and single-blade shearing, which is inefficient, has poor dimensional consistency, and requires frequent manual intervention. In the existing technology, although there are multi-line unwinding devices or rotary shearing mechanisms, the following problems exist: (1) uneven tension of multiple lines can easily lead to wire breakage when cutting copper wires with smaller diameters; (2) insufficient feeding accuracy results in large errors in the length of copper granules; (3) the single-blade shearing frequency is limited and difficult to match the needs of high-speed production. Therefore, it is urgent to design an integrated, high-precision multi-blade collaborative shearing device to meet the needs of large-volume, high-precision production. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-blade collaborative copper pellet shearing device, which solves the problems of low efficiency and poor precision in the prior art by multi-line synchronous unwinding, precise length feeding, and multi-blade collaborative shearing.

[0004] The technical solution adopted in this utility model is as follows:

[0006] A multi-wire copper wire unwinding component 1 includes an independently servo-driven unwinding wheel 101 and a tension controller 102, used to achieve synchronous unwinding of multiple wires.

[0007] The copper wire straightening component 2 is located behind the multi-wire copper wire unwinding device 1 and includes multiple sets of straightening rollers 201, which are used to eliminate the bending of the copper wire caused by winding.

[0008] The length-fixed clamping component 3 is located at the rear end of the copper wire straightening device 2 and includes a linked servo motor 301 and a photoelectric encoder 302, which are used to accurately convey copper wires according to a preset length.

[0009] The rotary shearing component 4 includes a disc-shaped blade holder 402 and multiple blades 401 evenly distributed on the disc-shaped blade holder 402. The rotary shearing mechanism 4 is driven to rotate by a variable frequency motor to achieve multi-blade coordinated shearing.

[0010] The copper particle collection component 5 includes a vibrating screening assembly 501 and a guide slide 502, which are used to classify and collect the sheared copper particles and transport them to the packaging station.

[0011] The copper wire straightening component 2 includes three sets of straightening rollers 201 arranged in an alternating manner, and the straightening rollers 201 are rotatably mounted on the roller frame.

[0012] The cutter head 401 is made of cemented carbide and the shearing surface is titanium-plated. The disc-type cutter holder 402 rotates at a speed of 100-120 r / min.

[0013] The vibrating screening mechanism 501 includes a vibrating housing and multiple layers of screens installed inside the vibrating housing.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0027] like Figure 1-5 This embodiment provides a multi-blade collaborative copper particle shearing device, including:

[0028] The multi-wire copper wire unwinding component 1 includes an independent servo-driven unwinding wheel 101 and a tension controller 102 for realizing synchronous unwinding of multiple wires; the synchronous drive motor of the multi-wire copper wire unwinding component 1 adopts a closed-loop control system, and the tension controller 102 is equipped with a pressure sensor to ensure that the tension error of multi-wire unwinding is within the allowable range.

[0029] The copper wire straightening component 2 is located behind the multi-wire copper wire unwinding component 1 and includes multiple sets of straightening rollers 201, which are used to eliminate the bending of the copper wire caused by winding.

[0030] The length-fixed feeding component 3, located at the rear end of the copper wire straightening component 2, includes a linked servo motor 301, a photoelectric encoder 302, and a feeding wheel assembly. It is used to precisely feed copper wire to a preset length. The feeding accuracy of the length-fixed feeding component 3 is ±0.1mm, and the maximum feeding speed is 2-3m / s. The feeding wheel assembly is part of the servo motor 301. Driven by the drive motor, the feeding wheel assembly feeds the copper wire to the shearing mechanism at a certain feed rate for shearing. Specifically, the feeding wheel assembly consists of parallel, grooved pressure rollers. Figure 3The servo motor 301 is a micro motor located inside the column.

[0031] The rotary shearing component 4 includes a disc-shaped blade holder 402 and multiple blades 401 evenly distributed on the disc-shaped blade holder 402. The rotary shearing mechanism 4 is driven to rotate by a variable frequency motor to achieve multi-blade coordinated shearing. The rotary shearing component 4 has 3 to 5 blades 401, and the blade spacing is adjustable to adapt to different copper wire diameters. The shearing frequency is 100 to 120 times / minute.

[0032] The copper particle collection component 5 includes a vibrating screening assembly 501 and a guide slide 502, which are used to classify and collect the sheared copper particles and transport them to the packaging station.

[0033] The copper wire straightening component 2 includes three sets of straightening rollers 201 arranged in an alternating manner, and the straightening rollers 201 are rotatably mounted on the roller frame.

[0034] The cutter head 401 is made of cemented carbide and the shearing surface is titanium-plated. The disc-type cutter holder 402 rotates at a speed of 100-120 r / min.

[0035] The vibrating screening assembly 501 includes a vibrating housing and two layers of screens installed inside the vibrating housing. The screen aperture diameter ranges from 8mm to 25mm, and is used to classify copper particles according to particle size. The screen aperture diameter can be switched according to product specifications to achieve precise classification.

[0036] The working principle of this utility model is as follows: 2-3 copper wires are fed onto the independent servo-driven unwinding rollers 101 of the multi-wire copper wire unwinding component 1, while the tension controller 102 adjusts the tension of each wire in real time. After being straightened by multiple sets of straightening rollers 201 of the straightening component 2, the copper wires enter the length-fixed clamping component 3. Driven by the servo motor 301, the clamping rollers precisely convey the copper wires to the rotary disc shearing component 4 according to a preset length. The cutter head 401 of the rotary disc shearing component 4 sequentially completes the shearing while rotating at high speed, and the sheared copper particles fall into the copper particle collecting component 5. The vibrating screening component 501 classifies the copper particles according to their size through multiple layers of screens. The classified copper particles are then conveyed to the collection box via the guide slide 502, completing the fully automated production process.
