The cutting mechanism further comprises a cutting driver and a transmission assembly, the cutting driver is connected with the two cutters through the transmission assembly respectively, and the cutting driver is used for driving the two cutters to be relatively close to or separated from each other. So set up, at the in-process of carrying out the cutting, two cutter relative movement to cutting the material from both sides simultaneously, cutting efficiency is high.

As shown in fig. 7-11, in one possible design, the cutting drive includes a cutting motor 21; the transmission assembly includes slide rail 22 and two glide structure 23, and each glide structure 23 all slides and assembles in slide rail 22, and two glide structure 23 are connected with two cutter one-to-one, all rotate on each glide structure 23 and are connected with eccentric wheel 24, and each eccentric wheel 24 all overlaps to be established and fixes the output shaft at cutting motor 21, and the output shaft of cutting motor 21 rotates and to drive two glide structure 23 along slide rail 22 antiport.

Alternatively, the eccentric wheel 24 and the transfer lever 26 are formed as an integral structure and manufactured through an integral molding process. The eccentric wheel 24 is connected with the corresponding sliding structure 23 through a second bearing in a rotating way. So arranged, during rotation of the output shaft, the eccentric 24 rotates relative to the sliding structure 23, and since the eccentric 24 has the feature of being eccentrically arranged, it can drive the sliding structure 23 to move up and down during rotation of the eccentric 24. Specifically, one side of the outer edge of the eccentric wheel 24 has the largest distance from the axis and the other side has the shortest distance from the axis, when the point of the eccentric wheel 24 having the largest distance from the axis rotates from the lower region of the axis to the upper region of the axis, the sliding structure 23 moves upward, and when the point of the eccentric wheel 24 having the smallest distance from the axis rotates from the lower region of the axis to the upper region of the axis, the sliding structure 23 moves downward.

Particularly, in the use process, one end of the material is contacted with the end part (also called a detection end) of the detection rod 31 of the micrometer after extending out of the gap between the two cutters, when the material moves outwards, the material pushes the detection rod 31 of the micrometer to move, the detection rod 31 detects the distance that the material pushes the detection rod to move, so that the length of the material extending out of the rear side of the cutters is obtained, namely the cutting length of the material, when the micrometer detects that the length of the material reaches the target length, the signal is fed back to the control mechanism, and the control mechanism controls the feeding mechanism to stop feeding, so that the material stops at the target length. For the convenience of cutting the material, the control mechanism controls the transmission assembly to enable the push plate 27 to push the detection rod 31 to the direction far away from the cutter, after the cutting is completed, the control mechanism controls the push plate 27 to return, and the detection rod 31 returns through self elasticity.

When the push plate 27 moves away from the cutter, the push plate 27 first moves relative to the claw 28, so that one side of the free end of the claw 28 enters into the through hole more, and the claw 28 is tightened to clamp the detection rod 31, and after the push plate 27 continues to move, the claw 28 holds the detection rod 31 tightly and drives the detection rod 31 to move away from the cutter. When the push plate 27 moves towards the direction close to the cutter, the claw 28 is reset under the self-elastic action, so that the detection rod 31 is released, and the detection rod 31 is reset under the self-elastic action.

The top of baffle box 43 is located the below of the gap between two cutters to make the material under the cutting directly fall into baffle box 43, baffle box 43 slope sets up, and the bottom of baffle box 43 is located the top of cup 42 that connects, so that the material under self action of gravity, gets into cup 42 that connects through baffle box 43. The counting sensor 44 may also be secured to the longitudinal support plate 52 by a support, and a photoelectric sensor may be used for the counting sensor 44, and when material passes the counting sensor 44, the counting sensor 44 sends a signal to the control mechanism to increase the count.

In this embodiment, the control mechanism may be a circuit board including a microcontroller MCU, a motor driver, and a control circuit of the communication interface.

For example, when the weight of the gold bar to be cut is 1g and the cutting deviation is ± 0.01g, a deviation range can be set to be ± 0.01g at a control mechanism, a preliminary target length can be calculated according to the thickness, the width and the density of the gold bar, and the target length can be set in the control mechanism. A primary cut is made according to the preliminary target length,

the cutting process is as follows:

the operator operates the manual adjustment and control mechanism 6 to lift the press roller 12, at which time the cutters remain open, i.e. the gap between the two cutters is relatively large.

The gold belt passes through the material guiding ring 72 and then sequentially passes through the gap between the two first rollers 71, the gap between the two second rollers and the gap between the two cutters to abut against the detection rod 31 of the micrometer.

The operator operates the manual regulating and controlling mechanism 6 to press the compression roller 12 downwards so as to compress the gold strip between the compression roller 12 and the feeding roller 11 through the compression roller 12, and the feeding is completed.

The control mechanism controls the feeding mechanism to work so as to convey the gold strip backwards, and the feeding mechanism stops feeding after the length measured by the micrometer reaches the target length.

The control mechanism controls the cutting mechanism to operate through the transmission assembly, and simultaneously controls the push plate 27 to push the detection rod 31 of the micrometer, so that a certain gap is kept between the detection rod 31 and the gold strip, the gold strip produced after the gold strip is cut can fall off, the cutting mechanism cuts the gold strip with the target length, and the cut part is called the gold strip.

The gold bar falls into the material guiding groove 43 and slides along the material guiding groove 43 to the material receiving cup 42 on the electronic scale 41.

The electronic scale 41 weighs the gold bar and uploads the data to the control mechanism.

And the control mechanism calculates the deviation between the actual weight and the target weight according to the actual weight, calculates the target length of the next cutting according to the deviation, and then executes the next feeding, cutting and weighing operation. After the above cycle is repeated for a plurality of times, the difference between the actual weight and the target weight of the gold bar is smaller and smaller, and the milligram-level precision can be finally achieved.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
