[0020] The embodiments of the present application will be described in more detail with reference to the drawings and reference signs, so that those skilled in the art can implement the present application after reading the specification. It should be understood that the specific examples described herein are only used to explain the present application, and are not intended to limit the present application.

[0021] The present application provides a lead plate slitting machine, comprising a slitting device 10 for shearing lead plates into multiple lead strips and a lead strip guiding device 20 for preventing lead strips from being skewed.

[0022] The slitting device 10 can refer to related technologies. Please refer to Figures 1-3 In the present embodiment, the slitting device 10 comprises a pair of slitting rollers 11 rotatably connected to the rack, the pair of slitting rollers 11 are respectively provided with 2 top cutting wheels 12 and 3 bottom cutting wheels 13 along the axial direction, the top cutting wheels 12 and the bottom cutting wheels 13 are arranged at intervals and staggered in sequence, when the lead plate enters between the top cutting wheels and the bottom cutting wheels, it is sheared into 5 lead strips, which are discharged from 3 gaps near the 2 top cutting wheels and 2 gaps between the 3 bottom cutting wheels, respectively, and there is a difference in discharge height, which is easy to cause the lead strips to be skewed due to collision and other factors, which is not conducive to subsequent pelletizing operation processing.

[0023] The lead strip guiding device 20 is arranged between the pair of slitting rollers 11, please refer to Figure 1 、 2The lead strip guiding device 20 comprises a bottom plate 21, a top plate 23 connected with the bottom plate 21 through two side plates 22, three bottom guiding strips 24 bolted on the bottom plate 21 and two top guiding strips 25 bolted in the recesses of the top plate 23. The bottom guiding strips 24 and the top guiding strips 25 are arranged along the axial direction of the slitting roller 11, thus, bottom guiding grooves 26 are formed between two adjacent bottom guiding strips 24, and there are two bottom guiding grooves 26 in total, top guiding grooves 27 are formed between two adjacent top guiding strips 25 and between the top guiding strips 25 and the adjacent side plates 22, and there are three top guiding grooves 27 in total. Meanwhile, the gap between any two adjacent bottom cutting wheels 13 corresponds to one bottom guiding groove 26, thus the lead strip discharged from the gap enters the bottom guiding groove 26 and is supported by the bottom plate 21; the gap on both sides of the top cutting wheel 12 corresponds to one top guiding groove 27, thus the lead strip discharged from the gap enters the top guiding groove 27 and is supported by the bottom guiding strip 24. Under the pushing of the top and bottom cutting wheels, the lead strip enters the two bottom guiding grooves 26 and the three top guiding grooves 27 respectively, and after being guided, the lead strip can be prevented from being skewed.

[0024] Please refer to Figure 5 The top guiding strip 25 is provided with a first curved surface 251 at one end of the slitting roller 11, the first curved surface 251 cooperates with the gap of the top cutting wheel 12, so that the top guiding strip 25 can extend to the vicinity of the top cutting wheel 12 and fill the gap between the two as much as possible. The bottom guiding strip 24 is provided with a second curved surface 241 at one end of the slitting roller 11, the second curved surface 241 cooperates with the gap of the bottom cutting wheel 13, so that the bottom guiding strip 24 extends to the vicinity of the bottom cutting wheel 13 and fills the gap between the two as much as possible, preventing the lead strip from being stuck in the gap. Similarly, the side plate 22 should also extend to the outside of the plurality of top and bottom cutting wheels to prevent the lead strip from deviating.

[0025] Please refer to Figure 6 The bottom guiding strip 24 comprises a first bottom guiding strip 24a, a second bottom guiding strip 24b and a third bottom guiding strip 24c, the projection of the second bottom guiding strip 24b on the bottom plate 21 is an isosceles trapezoid, the short bottom side of the isosceles trapezoid faces the slitting roller 11, and the first bottom guiding strip 24a and the third bottom guiding strip 24c are both provided with an inclined side parallel to the side surface of the second bottom guiding strip 24b at one side of the second bottom guiding strip 24b. The two inclined side surfaces of the second bottom guiding strip 24b can guide the lead strip to both sides, increasing the spacing between the two lead strips entering the bottom guiding groove 26.

[0026] Please refer to Figure 7The projections of the two top guide strips 25 on the bottom plate 21 are both right-angled trapezoids, the short bottom sides of the right-angled trapezoids are towards the slitting roller 11, and the right-angled waists of the two right-angled trapezoids are towards each other. The two oblique waist surfaces of the two top guide strips 25 can guide the lead strips to the two sides, and increase the spacing between the three lead strips entering the top guide groove 27. After the spacing between the five lead strips is increased, the feeding and granulation of the granulator are more favorable. The top of the end of the bottom guide strip 24 away from the slitting roller 11 is provided with an inclined surface 242, so that the three lead strips entering the top guide groove 27 move downward.

[0027] Further, the lead plate slitting machine further comprises a guide device provided at the end of the lead strip guide device 20 away from the slitting roller, for connecting the granulator. The guide device is provided with a plurality of independent guide channels, the guide channels should be matched with the lead strip gaps, and two bottom guide grooves and three top guide grooves are respectively communicated with a guide channel, forming five conveying channels, and a plurality of lead strips can be connected in sequence in a conveying channel, and under the extrusion of the top and bottom cutting wheels, the conveying from the lead plate slitting machine to the granulator is completed, and further ensures that no skewing phenomenon occurs.

[0028] The above is one or more embodiments of the present application, which is described in more detail and in more detail, but should not be understood as limiting the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
