Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a metal sheet slitting device, including a slitting frame 1. A slitting roller 2 and a support roller 3 located below the slitting roller 2 are movably installed inside the slitting frame 1. A plurality of evenly distributed slitting blades 4 are slidably sleeved on the outside of the slitting roller 2. A plurality of evenly distributed connecting components 5 are fixedly connected between adjacent slitting blades 4. A groove 6 is formed inside the sliding roller 2, and a slider 7 is slidably engaged inside the groove 6. The upper and lower ends of the slider 7 extend along the groove 6 to the upper and lower sides of the slitting roller 2 and are fixedly connected to the inner side of one of the middle slitting blades 4. An adjusting component 8 is movably sleeved inside the slider 7. Both ends of the adjusting component 8 penetrate the slider 7 and the support roller 3 and extend to the slitting frame. Outside the slitting frame 1, a drive motor 9 is installed. One end of the output shaft of the drive motor 9 is fixedly connected to one end of one of the adjusting components 8. One end of the slider 7 is fixedly connected to a connecting component 10. One end of the connecting component 10 is connected to a slitting blade 4 in the middle through the slider 7. The other end of the connecting component 10 extends to the outside of the slitting frame 1 through the slide groove 6 and is connected to a pump. Due to the setting of the connecting component 5, with the cooperation of the slider 7 and the connecting component 10, the position of several slitting blades 4 can be adjusted simultaneously by the pump. Thus, with the cooperation of the connecting component 5, the distance between two adjacent slitting blades 4 changes in a consistent manner, thereby effectively improving the adjustment efficiency of several slitting blades 4.

[0025] The connecting component 10 includes a conveying pipe and a return spring. The two ends of the conveying pipe are connected to the slider 7 and the pump, respectively. The water pipe is tied to the return spring by a cable tie. The two ends of the return spring are fixedly connected to the ends of the slider 7 and the inner cavity of the support roller 3, respectively.

[0026] The slitting blade 4 includes a blade disc 41 that is slidably engaged with the outer surface of the support roller 3. Except for the two blade discs 41 at both ends, the interior of the other blade discs 41 is provided with a number of through holes 42 that are evenly distributed and connected to the ends of the connecting components 5. The connecting components 5 between two adjacent blade discs 41 are interconnected through the through holes 42. The interior of the blade disc 41 is also provided with a connecting cavity 44 located at the end of the through hole 42 away from the axis of the blade disc 41. The number of through holes 42 in each blade disc 41 are interconnected through the connecting cavity 44.

[0027] Among them, a connecting hole 43 is provided inside the cutter head 41 located in the middle, which is connected to the bottom of the through hole 42. The lower end of the connecting hole 43 extends into the interior of the slider 7. A connecting groove 45 is provided inside the slider 7. One end of the connecting groove 45 is connected to the connecting hole 43, and the other end of the connecting groove 45 is connected to the conveying pipe.

[0028] The connecting component 5 includes a connecting sleeve 51 and a connecting liner 52 disposed between two adjacent cutter discs 41. The connecting sleeve 51 is sleeved on the outside of the connecting liner 52. The distal ends of the connecting sleeve 51 and the connecting liner 52 are respectively fixedly connected to the opposing surfaces of the two adjacent cutter discs 41 and connected to the corresponding through holes 42. A limiting spring 53 is provided inside the connecting sleeve 51. One end of the limiting spring 53 is abutted and connected to the cutter disc 41, and the other end of the limiting spring 53 is abutted and connected to the connecting liner 52.

[0029] The adjusting assembly 8 includes an adjusting screw 81 threaded into the slider 7. The two ends of the adjusting screw 81 pass through the slider 7 and the slitting roller 2 and extend to the two ends of the slitting frame 1. Two coaxial positioning bearing rings 83 are adjusted between the adjusting screw 81 and the slitting frame 1. A positioning sleeve 82 is sleeved between the facing surfaces of the two positioning bearing rings 83 through bearing balls. The other end of the positioning sleeve 82 is fixedly sleeved inside the slitting roller 2. The facing surfaces of the two positioning bearing rings 83 are respectively fixedly sleeved on the adjusting screw 81 and the slitting frame 1.

[0030] One end of a positioning sleeve 82 near the drive motor 9 passes through the positioning bearing ring 83 and extends to the outside of the slitting frame 1 and is fixedly connected to the output shaft of the drive motor 9. Due to the setting of the positioning bearing ring 83, the adjusting screw 81 and the slitting roller 2 can be positioned and supported respectively. Moreover, with the cooperation of the corresponding positioning sleeve 82 and the positioning bearing ring 83, the drive motor 9 can drive the slitting roller 2 to rotate through the connected positioning bearing ring 83, without affecting the rotation of the adjusting knob 86 and the adjusting screw 81.

[0031] The adjusting screw 81 has a limiting block 84 internally slidably engaged at the end away from the drive motor 9. The outer surface of the limiting block 84 is polygonal. One end of the limiting block 84 is fixedly connected to a connecting rod 85. The other end of the connecting rod 85 passes through the adjusting screw 81 and extends to the outside of the slitting frame 1 and is fixedly connected to an adjusting knob 86. Due to the setting of the adjusting screw 81, under the restriction of the slide groove 6, the slider 7 can drive a central blade 41 to move left and right along the outside of the slitting roller 2, thereby positioning it at the top of the middle of the slitting plate. This allows the remaining slitting blades 4 on both sides to align with the sides of the slitting plate after they move closer or further away, thereby improving the slitting accuracy.

[0032] The adjusting screw 81 is internally equipped with a positioning spring 87 located outside the connecting rod 85. One end of the positioning spring 87 is abutted against the inner wall of the adjusting screw 81, and the other end is abutted against the limiting block 84. The adjusting knob 86 is fixedly connected to a locking tooth 88 on the side near the slitting frame 1. The locking tooth 88 extends into the interior of the positioning bearing ring 83 and meshes with the corresponding positioning sleeve 82. Due to the setting of the positioning spring 87, under the action of its elastic restoring force, the adjusting knob 86 is pulled by the limiting block 84 and the connecting rod 85, so that the locking tooth 88 on the side of the adjusting knob 86 can always be tightly engaged with the positioning sleeve 82. This can prevent the adjusting knob 86 from rotating accidentally when the slitting roller 2 rotates, while not affecting the operator's ability to actively rotate the adjusting knob 86 to adjust the adjusting screw 81.

[0033] Working principle and usage process of this utility model:

[0034] First, place the front end of the slitting plate between the slitting roller 2 and the support roller 3. Then, adjust the position of the middle cutter disc 41 according to the slitting plate. Specifically, pull the adjustment knob 86 to disengage the locking tooth 88 on its side from the positioning sleeve 82. At the same time, pull the limiting block 84 through the connecting rod 85 and compress the positioning spring 87. Then, rotate the adjustment knob 86 to drive the adjustment screw 81 to rotate through the connecting rod 85 and the limiting block 84. Then, under the restriction of the slide groove 6, the slider 7 drives the middle cutter disc 41 fixedly connected to it to move laterally until the middle cutter disc 41 moves to the top of the middle of the slitting plate.

[0035] Then, the pump is turned on to adjust the internal pressure of the connecting assembly 5 with the help of the conveying pipe. With the help of the limit spring 53, the internal pressure of several connecting assemblies 5 is kept consistent, so that the length of several connecting assemblies 5 after extension and retraction is the same, thus making the distance between adjacent cutter discs 41 consistent. When the distance between the two cutter discs 41 on both sides and the sides of the cutting plate is consistent with the distance between adjacent cutter discs 41, the drive motor 9 is turned on to drive the slitting roller 2 to rotate through the corresponding positioning sleeve 82, which in turn drives several cutter discs 41 to rotate, thus completing the slitting with the help of the slitting roller 2.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
