Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1, the pre-distributed copper strip path provided with the arc-shaped platform longitudinal shearing and cutting device comprises a frame, a detection storage device, a force unloading device, a feeding device 2 and a cutting device 3, wherein the detection storage device is arranged on the frame and used for detecting whether the thickness of a copper strip 1 reaches the standard, the force unloading device is used for eliminating the stress of the copper strip 1, the feeding device is used for conveying the copper strip 1, and the cutting device is used for cutting the copper strip 1; copper strips 1 detects through the thickness that detects storage device, coils temporary storage after thickness detects qualified, and the during operation carries out stress relief through the power unloading device earlier, then transports cutting device 3 through material feeding unit 2 and cuts and send out again.

As shown in fig. 1 and 2, the force-discharging device includes a force-discharging bracket, a front guide roller 4 and a rear guide roller 5 rotatably disposed on the force-discharging bracket and spaced apart from each other, and a driving member disposed on the bracket for driving the front guide roller 4 and the rear guide roller 5 to rotate.

The front guide roller 4 and the rear guide roller 5 are the same, and the copper strip 1 passes through the front guide roller 4 and the rear guide roller 5 in sequence during conveying.

The driving part comprises a front driven gear 6 fixedly arranged on a rotating shaft of the front guide roller 4, a rear driven gear 7 fixedly arranged on a rotating shaft of the rear guide roller 5, a front driving gear 8 and a rear driving gear 9 which are rotatably arranged on the force unloading support, a front belt wheel coaxially fixed with the front driving gear 8, a rear belt wheel coaxially fixed with the rear driving gear 9, a belt 10 tightly sleeved on the front belt wheel and the rear belt wheel, and a force unloading motor and transmission assembly 11 fixedly arranged on the force unloading support and used for driving the rear belt wheel to run.

The specifications of the front belt wheel and the rear belt wheel are consistent, and the speed and the direction of the front belt wheel and the rear belt wheel are the same in the operation process; the radiuses of the front driving gear 8 and the rear driving gear 9 are the same, the outer ring of the rear driving gear 9 is full teeth, and the outer ring of the front driving gear 8 only has continuous teeth of 180 degrees; the radius of the front driven gear 6 is half of the radius of the rear driven gear 7; the tooth parameters of the front driven gear 6, the rear driven gear 7, the front driving gear 8 and the rear driving gear 9 are the same; the front drive gear 8 is engaged with the front driven gear 6, and the rear driven gear 7 is engaged with the rear drive gear 9 so as to be engaged when the teeth of the two are in contact with each other.

In order to make the copper strip 1 hang between the front guide roller 4 and the rear guide roller 5 and droop to eliminate the attraction, the front guide roller 4, the rear guide roller 5 and the rotation benefit need to be specially designed, so the driving component needs to be specially designed, in order to clearly understand the operation principle of the driving component, the invention adopts the physics angle to explain the principle of adopting the structure:

in order to ensure that the total inlet and outlet amounts of the front and rear copper strips 1 are consistent (namely the inlet amount of the copper strips 1 entering from the front guide roller 4 and the outlet amount of the copper strips 1 sent out from the rear guide roller 5), data analysis is performed from the angles of physical linear velocity and angular velocity.

Firstly, the following assumptions are made: t (this period makes the front drive gear 8 and the rear drive gear 9 rotate exactly one turn), V (front roller) is the linear velocity of the rotation process of the front guide roller 4, V (rear roller) is the linear velocity of the rotation process of the rear guide roller 5, and then: the feeding quantity S (in) of the copper strip 1 from the front guide roller 4 is equal to V (front roller)_·t, the discharge amount S (out) of the copper strip 1 from the rear guide roll 5 becomes V (rear roll)_·t, the balance of the inlet and outlet amounts of the copper strip 1 can be achieved only when S (inlet) is equal to S (outlet), so that the two data are required to be ensured to be the same in the design process;

from the above, the variable of S (in) is determined by V (front roll), V (back roll) and t, so the design idea is to change the values of these variables;

then, since the front guide roller 4 and the rear guide roller 5 are the same, the radii of the front guide roller 4 and the rear guide roller 5 are the same, assuming that the radii of the front guide roller 4 and the rear guide roller are r (rollers), and on the premise that the angular velocity and the linear velocity formula v is wr, the design of the linear velocity of the front guide roller 4 and the rear guide roller 5 is actually the design of the angular velocity of the front guide roller and the rear guide roller, and the front guide roller 4 and the rear guide roller 5 are respectively defined as W (front rollers) and W (rear rollers);

in the present invention, the front drive gear 8 and the rear drive gear 9 are synchronously driven and operated by the front pulley and the rear pulley with the same specification parameters, so the rotation speeds of the two are also the same, the rotation speed of the front drive gear 8 is defined as W (front drive), the rotation speed of the rear drive gear 9 is defined as W (rear drive), W (front drive) is equal to W (rear drive), and the radii of the front drive gear 8 and the rear drive gear 9 are also the same, so the linear speeds of the outer rings of the two gears in the operation process are also the same, the linear speed of the outer ring of the front drive gear 8 is defined as V (rear drive), the linear speed of the outer ring of the rear drive gear 9 is defined as V (rear drive), and V (front drive) is equal to V (rear drive);

assuming that the rotation speed of the front driven gear 6 is W (front slave), the radius is r (front slave), and the operation linear speed of the outer ring gear is V (front slave), the rotation speed of the rear driven gear 7 is W (rear slave), the radius is r (rear slave), and the operation linear speed of the outer ring gear is V (rear slave), since the radius of the front driven gear 6 is half of the radius of the rear driven gear 7, 2r (front slave) is r (rear slave), while the front driven gear 6 is used for driving the front guide roller 4, and the rear driven gear 7 is used for driving the rear guide roller 5, W (front slave) is W (front roller), and W (rear slave) is W (rear roller);

since the rear driven gear 7 is always meshed with the rear drive gear 9 and the front driven gear 6 is meshed with the front drive gear 8 in a half cycle, V (front drive) ═ V (rear drive) ═ V (front slave) ═ V (rear slave), and after r (front slave) ═ 2r (rear slave) conversion, we obtain 2W (rear roller) ═ W (front roller), that is: in the case where the front driven gear 6 is meshed with the teeth of the front drive gear 8, the rotation speed of the rear guide roller 5 is only half of the rotation speed of the front guide roller 4;

since the front drive gear 8 has teeth only in the range of 180 °, the front drive gear 8 meshes with the front driven gear 6 and rotates the front guide roller 4 only half of the time in the period range of t, and we divide t into two stages with equal length, where the stage t1 is the stage when the front drive gear 8 meshes with the front driven gear 6, the stage t2 is the stage when the front drive gear 8 and the front driven gear 6 are staggered, and t1 is t2, and t1+ t2 is t;

during stage t 1: the front guide roller 4 and the rear guide roller 5 rotate, and the rotating speed of the front guide roller 4 is twice that of the rear guide roller 5, so that the feeding efficiency of the copper strip 1 is higher than the discharging efficiency, at this time, the copper strip 1 is automatically hung down and is in a state shown in figure 1, and the self-stress relief of the copper strip 1 is completed at this stage;

during stage t 2: the front guide roller 4 does not rotate any more and is in a stagnation state, and the rear guide roller 5 continues to rotate so as to send the copper strip 1 hung between the front guide roller 4 and the rear guide roller 5 out of the force unloading device;

furthermore, it is derived from the formula that, in the time of one period t: the combination of W (front roll) · r (roll) · t1 and S (out) · W (rear roll) · (t1+ t2) and 2W (rear roll) · W (front roll) and t1 ═ t2 can obtain S (in) ═ S (out), i.e. ensure the front-back balance of the amount fed in a period.

As shown in fig. 3 and 4, the detecting and storing device includes a detecting support 12, a storage reel 13 to be detected and a storage reel 14 to be detected which are rotatably disposed on the detecting support 12, a left slide rail and a right slide rail which are vertically and fixedly disposed on the detecting support 12, a left upper slide block and a left lower slide block which are arranged on the left slide rail in a lifting manner, a right upper slide block and a right lower slide block which are arranged on the right slide rail in a lifting manner, an upper detecting roller 15 which is arranged between the left upper slide block and the right upper slide block in a rotating manner, a lower detecting roller 16 which is arranged between the left lower slide block and the right lower slide block in a rotating manner, and an elastic element 17 which is used for driving the left upper slide block and the left lower slide block and the right upper slide block and the right lower slide block to approach each other; the upper detection roller 15 and the lower detection roller 16 are provided with gaps for the copper strip 1 to pass through, and the copper strip 1 wound on the storage reel 13 to be detected is subjected to thickness inspection through the gaps and then wound on the storage reel 14 to be detected for temporary storage so as to be subjected to the next process; visual monitoring base pieces are arranged on the upper right sliding block and the lower right sliding block, and a visual angle detector is arranged on the detection support 12 to read the distance between the visual monitoring base pieces according to a visual angle; a limiting part 18 is arranged between the left upper slide block and the left lower slide block.

In the operation process, the copper strip 1 passes through the gap and then extrudes the upper detection roller 15 and the lower detection roller 16, so that the thickness of the copper strip 1 can be known by detecting the distance between the two visual monitoring base parts through the visual angle detector.

As shown in fig. 5, the limiting member 18 includes a housing having an inner cavity, a worm 19 transversely rotatably disposed on the housing, a turbine shaft 20 vertically rotatably disposed in the housing, a forward screw 21 fixedly disposed above the turbine shaft, a reverse screw 22 fixedly disposed below the turbine shaft, a vertical rod 23 fixedly disposed in the housing, a forward slider 24 and a reverse slider 25 slidably disposed on the vertical rod, a forward screw hole is disposed at the bottom of the forward slider, the forward screw is rotatably disposed in the forward screw hole, a reverse screw hole is disposed at the bottom of the reverse slider, and the reverse screw is rotatably disposed in the screw hole.

In order to enable the copper strip 1 to be smoothly led into the gap and prevent the upper detection roller 15 and the lower detection roller 16 from being pressed together in an initial state, the limiting piece 18 is adopted in the invention to block the joint of the upper left slider and the lower left slider so as to indirectly avoid the complete joint of the upper detection roller 15 and the lower detection roller 16, and the forward slider and the reverse slider for limiting the movement of the upper detection roller 15 and the lower detection roller 16 can also adjust the relative width distance through the worm gear, so that the minimum value of the gap can be preset.
