[0002] Silicon steel sheets are a key material used in transformer production. Transformer cores are formed by stacking cut sheets in a specific order. To facilitate access to the appropriate sheet, production sites typically categorize and stack the sheets according to their specifications. During the core stacking process, the appropriate sheet is retrieved and stacked as needed. However, these stacked sheets are often placed around the operator stacking the core, requiring them to turn or even move to retrieve the required sheet. This unnecessary turning or movement significantly reduces operational efficiency. Summary of the Invention

[0019] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the present invention.

[0020] See also Figure 1-Figure 3 The silicon steel sheet stacking and conveying device shown includes an operating part 10, a control part 20, an execution part 30 and a sliding part 40. The control part 20 is connected between the operating part 10 and the execution part 30, and the sliding part 40 is installed on the execution part 30 and moves with the execution part 30.

[0021] The operating unit 10 comprises a base block 11, a connecting rod 12, and a pedal 13. The connecting rod 12 is hingedly connected to the base block 11, with the pedal 13 mounted at the end of the connecting rod 12. The middle of the connecting rod 12 is hingedly connected to the control unit 20. The top of the base block 11 has two ears 111, which are hingedly connected to the connecting rod 12. The front end of the connecting rod 12 has a front ear piece 121, which is hingedly connected to the ears 111. The middle of the connecting rod 12 has a middle ear piece 122, which is hingedly connected to the control unit 20. The rear of the connecting rod 12 has two holes 123, in which the pedal 13 is mounted.

[0022] The control part 20 includes a vertical rod 21, a guide block 22, a dovetail slider 23 and a return spring 24. The bottom of the vertical rod 21 is hinged to the middle ear piece 122 of the connecting rod 12 through an ear piece. The middle part of the vertical rod 21 has an oblique groove 211. The upper and lower end faces of the oblique groove 211 are both beveled. The bevel cooperates with the conical teeth 33 of the executive part 30. The vertical rod 21 is fitted on the guide block 22, and the guide block 22 is rotatably mounted on the frame (not shown in the figure). The guide block 22 guides the movement of the vertical rod 21. The vertical rod 21 will deflect at a small angle during the movement. The guide block 22 cooperates with the small angle offset of the vertical rod 21 and guides the overall movement of the vertical rod 21. The top of the vertical rod 21 is connected to the return spring 24, and the top of the return spring 24 is connected to the dovetail slider 23. The dovetail slider 23 is slidably mounted on the sliding part 40.

[0023] The actuator 30 includes a crossbeam 31, a mounting post 32, a tapered tooth 33, a through slot 34, a limit block 35 and a tensioning spring 36. The mounting posts 32 are inserted into each end of the crossbeam 31, and the sliding part 40 is installed on the mounting post 32. The crossbeam 31 has staggered tapered teeth 33 on the upper and lower surfaces. The staggered tapered teeth 33 cooperate with the oblique groove 211 of the vertical rod 21 for movement. The crossbeam 31 has a transverse through slot 34 in the center, and the limit block 35 is fitted in the through slot 34. The limit block 35 is installed on the frame (not shown in the figure) and plays a role in limiting and guiding the translation of the crossbeam 31. A tensioning spring 36 is connected between the limit block 35 and the mounting post 32 on the right side. Under the action of the tensioning spring 36, the crossbeam 31 always has a tendency to move to the left, and the oblique groove 211 of the vertical rod 21 cooperates with the tapered teeth 33 to prevent the crossbeam 31 from moving to the left unless external force acts.

[0024] The sliding part 40 includes a support rod 41, a platform 42, a partition 43 and a dovetail groove 44. There are four support rods 41 under the platform 42. The support rods 41 are connected to the mounting column 32. Partitions 43 are evenly distributed on the platform 42. The partitions 43 are used to distinguish silicon steel sheets of different specifications. The cut partitions 43 are classified and placed between the partitions 43 on the platform 42. There is a dovetail groove 44 at the bottom of the platform 42. The dovetail slider 23 is slidably installed in the dovetail groove 44. With the cooperation of the dovetail slider 23 and the dovetail groove 44, no matter how the sliding part 40 moves, the dovetail slider 23 is always located above the vertical rod 21, maintaining the vertical tension of the return spring 24 on the vertical rod 21.

[0025] The working principle of the present invention is: the cut silicon steel sheets are placed on the platform 42 in a classified manner, and the best is to place them according to the stacking order of the silicon steel sheets. When the pedal 13 is stepped on, the pedal 13 drives the vertical rod 21 to move downward. At this time, the bevel groove 211 of the vertical rod 21 releases a conical tooth 33 below. At this time, the crossbeam 31 drives the sliding part 40 to move to the right together under the action of the tension spring 36. Subsequently, the bevel angle above the bevel groove 211 limits the conical tooth 33 on the upper side of the crossbeam 31. After releasing the pedal 13, the vertical rod 21 moves upward under the action of the reset spring 24. The bevel angle above the bevel groove 211 releases a conical tooth 33, and the bevel angle below the bevel groove 211 immediately limits the conical tooth 33 on the lower side of the crossbeam 31. The platform 42 completes a cycle of movement and moves the silicon steel sheet to a position suitable for the operator to pick up. The above operation is then repeated, and the platform 42 gradually moves the silicon steel sheet.

[0026] The above embodiments primarily illustrate the silicon steel sheet stacking and conveying apparatus of the present invention. While only a limited number of embodiments and technical features have been described, those skilled in the art will appreciate that the present invention may be implemented in numerous other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and alternatives without departing from the spirit and scope of the present invention as defined by the appended claims.
