Description

Technical Field

[0001] The utility model belongs to the technical field of quantitative wire cutting, and in particular relates to a quantitative wire cutting device for processing electronic wires. Background Art

[0002] Electronic wires include USB transmission cables, audio cables, mouse cables, speaker cables, etc. During the production process, electronic wires are transported to the wire cutting machine through a machine for cutting to a suitable quantitative length.

[0003] During the conveying and cutting process of existing electronic wires, when the cutting knife is cutting, the wire bundle is sometimes easily carried out a distance due to the loosening of the conveyed wire bundle and the cutting pressure, which makes it difficult to achieve quantitative cutting of the electronic wire. Therefore, a quantitative cutting device for electronic wire processing is needed to solve the above problem. Utility Model Content

[0004] The purpose of the present invention is to provide a quantitative wire cutting device for processing electronic wires, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a quantitative wire cutting device for processing electronic wire materials, comprising a bottom block, wherein two connecting blocks are fixedly provided on the bottom block, and a positioning roller, a connecting roller and two discharging rollers are arranged between the two connecting blocks and rotated together from left to right in sequence, and a connecting frame is fixedly provided on the two connecting blocks, and a first cylinder is provided on the connecting frame, and a connecting block is fixedly provided on the bottom end of the first cylinder, and a pressure roller is provided on the lower surface of the connecting block, and the pressure roller is located between the two connecting blocks, and a pressure ring block is provided on the pressure roller, and a pressure ring groove is provided on the pressure ring block, and a discharging ring block is fixedly provided on the front sides of the two connecting blocks, and a discharging hole is provided on the discharging ring block, and a fixing frame is fixedly provided on the bottom block, and a second cylinder is fixedly provided on the fixing frame, and a cutting knife is fixedly provided on the bottom end of the second cylinder, and a driving mechanism is provided on the connecting block on one side.

[0006] By setting a pressure roller, the pressure roller can be driven downward and pressed by the connecting block under the operation of the first cylinder, so that the gap between the roller surfaces of the pressure roller and the positioning roller gradually becomes smaller, so that the wire bundle passing through the positioning roller can be pressed to a certain extent under the pressure of the pressure ring block on the pressure roller. At this time, when the two discharging rollers are driven to convey the wire bundle, the loose wire bundle that may exist between the discharging roller and the positioning roller will be calculated and pulled out in advance, so that the wire bundle after the compression point of the positioning roller and the pressure roller where the wire bundle is located can be straightened, and then the wire bundle of the positioning roller and the discharging roller is conveyed and tightened through the two discharging rollers, which helps to ensure that the tangent line of the cutting knife at the discharge hole will not be easily stretched due to the cutting pressure of the cutting knife and the looseness of the wire bundle between the positioning roller and the discharging roller, thereby helping to ensure the quantitative cutting effect of the electronic wire.

[0007] As a preferred embodiment, the pressing roller is located obliquely above the positioning roller.

[0008] By arranging the pressure roller to be located obliquely above the positioning roller, when the pressure roller moves downward through the extension and contraction of the first cylinder, the pressure ring block on the pressure roller will press on the wire harness on the positioning roller below through the pressure ring groove, so that when the pressure roller does not completely rest on the surface of the positioning roller, it can tighten and press the wire harness between the positioning roller and the connecting roller to a certain extent, thereby helping to ensure a stable conveying effect of the electronic wire harness.

[0009] As a preferred embodiment, the driving mechanism includes a fixed block, the fixed block is fixedly arranged on the bottom block, and the motor is fixedly arranged on the fixed block.

[0010] As a preferred embodiment, gears are fixedly provided at the rotation locations of the two discharging rollers.

[0011] As a preferred embodiment, the two gears are meshed with each other.

[0012] As a preferred embodiment, one side of the motor is fixedly connected to one side of the gear below.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a pressure roller, which can be driven by the connecting block to move down and press the pressure roller under the operation of the first cylinder, so that the gap between the roller surfaces of the pressure roller and the positioning roller gradually becomes smaller, thereby enabling the wire bundle passing through the positioning roller to be pressed and fixed to a certain extent under the pressure of the pressure ring block on the pressure roller. At this time, when the two discharging rollers are driven to convey the wire bundle, the loose wire bundle that may exist between the discharging roller and the positioning roller will be calculated and pulled out in advance, so that the wire bundle after the compression point of the wire bundle where the positioning roller and the pressure roller are located can be straightened, and then the wire bundle of the positioning roller and the discharging roller is conveyed and tightened through the two discharging rollers, thereby helping to ensure that the tangent line of the cutting knife at the discharging hole will not be easily stretched due to the cutting pressure of the cutting knife and the looseness of the wire bundle between the positioning roller and the discharging roller, thereby helping to ensure the quantitative cutting effect of the electronic wire.

[0015] The utility model arranges a pressure roller obliquely above the positioning roller. When the pressure roller moves downward through the extension and contraction of the first cylinder, the pressure ring block on the pressure roller will press on the wire harness on the positioning roller below through the pressure ring groove, so that when the pressure roller does not completely rest on the surface of the positioning roller, it can tighten and press the wire harness between the positioning roller and the connecting roller to a certain extent, thereby helping to ensure a stable conveying effect of the electronic wire harness.

A pressure ring block 10 is provided on the pressure roller 9, and a pressure ring groove 11 is provided on the pressure ring block 10. A discharging ring block 12 is fixedly provided on the front of the two connecting blocks 2, and a discharging hole 13 is provided on the discharging ring block 12.

A cutting knife 16 is fixedly provided at the bottom end of the second cylinder 15, and a driving mechanism 17 is provided on the connecting block 2 on one side.

[0025] By setting the pressure roller 9, the pressure roller 9 can be driven to move down and press through the connecting block 8 under the operation of the first cylinder 7, so that the gap between the roller surfaces of the pressure roller 9 and the positioning roller 3 gradually becomes smaller, so that the wire bundle passing through the positioning roller 3 can be pressed to a certain extent under the pressure of the pressure ring block 10 on the pressure roller 9. At this time, when the two discharging rollers 5 are driven to convey the wire bundle, the loose wire bundle that may exist between the discharging roller 5 and the positioning roller 3 will be calculated and pulled out in advance, so that the wire bundle after the compression point of the positioning roller 3 and the pressure roller 9 where the wire bundle is located can be straightened, and then the wire bundle of the positioning roller 3 and the discharging roller 5 is conveyed and tightened by the two discharging rollers 5, which helps to ensure that the tangent line of the cutting knife 16 at the discharge hole 13 will not be easily stretched due to the cutting pressure of the cutting knife 16 and the looseness of the wire bundle between the positioning roller 3 and the discharging roller 5, thereby helping to ensure the quantitative cutting effect of the electronic wire.

[0026] The pressure roller 9 is located obliquely above the positioning roller 3 .

[0027] By arranging the pressure roller 9 to be located obliquely above the positioning roller 3, when the pressure roller 9 moves downward through the extension and contraction of the first cylinder 7, the pressure ring block 10 on the pressure roller 9 will press on the wire harness on the positioning roller 3 below through the pressure ring groove 11, so that when the pressure roller 9 does not completely rest on the surface of the positioning roller 3, it can tighten and press the wire harness between the positioning roller 3 and the connecting roller 4 to a certain extent, thereby helping to ensure a stable conveying effect of the electronic wire harness.

[0028] The driving mechanism 17 includes a fixed block 171 . The fixed block 171 is fixedly mounted on the bottom block 1 . A motor 172 is fixedly mounted on the fixed block 171 .

[0029] Gears 173 are fixedly provided at the rotation points of the two discharging rollers 5 .

[0030] Both gears 173 mesh with each other.

[0031] One side of the motor 172 is fixedly connected to one side of the lower gear 173 .

[0032] By setting up a motor 172, the upper gear 173 is synchronously driven to rotate by the lower gear 173 under the operation of the motor 172, and the meshing rotation of the two gears 173 drives the two discharge rollers 5 to convey and rotate, so that the wire harness can be conveyed to the discharge hole 13 and extended out, and then driven by the second cylinder 15 to drive the cutting knife 16 to cut the electronic wire harness.

[0033] The working principle and use process of the present invention are as follows: first, by setting a pressure roller 9, the pressure roller 9 can be driven to move downward and press through the connecting block 8 under the operation of the first cylinder 7, so that the gap between the roller surfaces of the pressure roller 9 and the positioning roller 3 gradually becomes smaller, thereby making the wire bundle passing through the positioning roller 3 can be pressed and fixed to a certain extent under the pressure of the pressure ring block 10 on the pressure roller 9. This is achieved by setting a motor 172. Under the operation of the motor 172, the gear 173 below synchronously drives the gear 173 above to rotate. The meshing rotation of the two gears 173 drives the two discharging rollers 5 to convey and rotate, so that the wire bundle can be conveyed to the discharging hole 13 and stretched out. The loose wire bundle that may exist between the discharging roller 5 and the positioning roller 3 will be calculated and pulled out in advance, so that the positioning roller 3 and the pressure roller 9 The wire harness after the compression point of the wire harness is straightened, and then the wire harness between the positioning roller 3 and the discharge roller 5 is conveyed and tightened through the two discharge rollers 5, which helps to ensure that the tangent line of the cutting knife 16 at the discharge hole 13 will not be easily stretched due to the cutting pressure of the cutting knife 16 and the looseness of the wire harness between the positioning roller 3 and the discharge roller 5. In addition, by arranging the pressure roller 9 to be located obliquely above the positioning roller 3, when the pressure roller 9 is moved downward by the extension and contraction of the first cylinder 7, the pressure ring block 10 on the pressure roller 9 will be pressed on the wire harness on the lower positioning roller 3 through the pressure ring groove 11, so that when the pressure roller 9 does not completely rest on the surface of the positioning roller 3, it can tighten and press the wire harness between the positioning roller 3 and the connecting roller 4 to a certain extent, thereby helping to ensure the stable conveying effect of the electronic wire harness.
