Description

Technical Field

[0001] The utility model belongs to the technical field of transformer manufacturing, and in particular relates to an upper magnetic attraction mechanism for an iron core silicon steel sheet. Background Art

[0002] In the production of silicon steel sheets, the rolled steel sheet raw material rolls need to be cut obliquely to form long sheets of trapezoidal silicon steel sheets. After cutting and forming, the silicon steel sheets need to be sorted and stored for future use.

[0003] In order to improve the efficiency of silicon steel sheet sorting, some manufacturers currently use electromagnetic conveyor belts to absorb silicon steel sheets at the discharge end of the bevel cutting mechanism, drive the silicon steel sheets to move to the top of the sorting table, and then cut off the power. At this time, the magnetic force of the electromagnetic conveyor belt disappears, and the silicon steel sheets fall onto the sorting table. Then continue to power on, and the electromagnetic conveyor belt absorbs the next group of silicon steel sheets at the discharge end of the bevel cutting mechanism. Through such a cycle, the silicon steel sheets can be stacked efficiently, and finally the staff can slightly sort out the silicon steel sheet pile. However, this method requires the electromagnetic conveyor belt to be frequently powered off and powered on, resulting in a sudden increase in the power consumption generated by the electromagnetic conveyor belt, which increases production costs. At the same time, only one group of silicon steel sheets can be transferred at a time, and the transfer efficiency is low. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides an upper magnetic suction mechanism for iron core silicon steel sheets, which enables the silicon steel sheets to be separated from the magnetic conductive plate and the conveyor belt without power off by passing through the gap between the magnetic conductive plate and the conveyor belt through a material unloading push plate and pushing the silicon steel sheets. At the same time, the entire material unloading and material sorting process is carried out continuously, thereby improving the material transfer efficiency.

[0005] The specific technical solution adopted by the utility model is:

[0006] A magnetic suction mechanism for an iron core silicon steel sheet on the upper side comprises a frame and a magnetically conductive plate fixedly connected to the frame and a conveyor belt, wherein the magnetically conductive plate and the conveyor belt are respectively connected to the frame and suspended above the discharge end of a bevel cutting mechanism and a tidying table, wherein the magnetically conductive plate is located on the inner ring of the conveyor belt and close to the lower surface of the conveyor belt, and the silicon steel sheet is adhered to the outer ring surface of the conveyor belt with the help of the magnetically conductive plate and is moved from the discharge end of the bevel cutting mechanism to above the tidying table with the help of the conveyor belt, and further comprises a unloading mechanism, wherein the unloading mechanism comprises an unloading push plate and an unloading telescopic cylinder, and a unloading gap for the unloading push plate to pass through is arranged on the conveyor belt and the magnetically conductive plate, and the unloading push plate pushes the silicon steel sheet off the conveyor belt along the gap with the help of the unloading telescopic cylinder.

[0007] The conveyor belt comprises symmetrically arranged driving rollers and two rows of driving belt bodies which rotate with the help of the driving rollers. A material discharge gap for a material discharge push plate to pass through is arranged between the driving belt bodies. The width of the material discharge gap is smaller than the width of the silicon steel sheet.

[0008] The conveyor belt also includes an elastic belt body and a guide roller. The elastic belt body is located in the unloading gap, and the guide roller is located above the driving roller. The elastic belt body is wrapped around the outer side of the conveyor belt and the unloading mechanism with the help of the guide roller and the driving roller. The unloading push plate pushes the silicon steel sheet off the conveyor belt with the help of the lower surface of the elastic belt body.

[0009] The conveyor belt also includes a limiting shaft, which is symmetrically arranged on both sides of the unloading push plate. The elastic belt body is suspended above the plane where the driving belt body is located with the help of the limiting shaft, and the lower side busbar of the limiting shaft is located above the plane where the driving belt body is located.

[0010] The unloading mechanism is arranged in multiple groups at equal intervals along the feeding direction. When the unloading push plate is extended by means of the unloading telescopic cylinder, the angle a between the elastic belt body between the limiting shaft and the side of the unloading push plate and the driving belt body is 20-30°.

[0011] The height difference between the discharging end of the beveling mechanism and the lower surface of the conveyor belt is 1-2 cm, and the height difference between the sorting table and the lower surface of the conveyor belt is 15-30 cm.

[0012] The beneficial effects of the utility model are:

[0013] The utility model is additionally provided with a feeding mechanism and a feeding gap is arranged on the conveyor belt on the magnetic guide plate. When in use, the silicon steel sheet at the discharging end of the bevel cutting mechanism is adsorbed on the conveyor belt with the help of the magnetic guide plate and is moved with the help of the conveyor belt. When the silicon steel sheet moves to the top of the sorting table, the feeding pushing plate is extended along the gap with the help of the feeding telescopic cylinder to push the silicon steel sheet away from the magnetic guide plate. When the feeding pushing plate is extended to the farthest end, the gravity of the silicon steel sheet is greater than the suction force of the magnetic guide plate on the silicon steel sheet. At this time, the silicon steel sheet falls onto the sorting table, and subsequent silicon steel sheets repeat the above operation and stacks are formed between the silicon steel sheets. Finally, the stacked silicon steel sheets can be simply sorted by the staff. The magnetic guide plate can be a permanent magnet or an electromagnet. The electromagnet can be continuously energized without power off, which reduces the energy consumption of the feeding process. At the same time, the entire feeding and sorting process is carried out continuously, and multiple spaced silicon steel sheets can be located on the conveyor belt at the same time, and feeding is carried out in sequence, thereby improving the material transfer efficiency.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] Specific embodiments, such as Figure 1-3 As shown, the utility model provides an upper magnetic suction mechanism for iron core silicon steel sheets, comprising a frame 1 and a magnetically conductive plate 2 fixedly connected to the frame 1 and a conveyor belt, the magnetically conductive plate 2 and the conveyor belt are respectively connected to the frame 1 and suspended above the discharge end 3 of the bevel cutting mechanism and the sorting table 4, the magnetically conductive plate 2 is located on the inner ring of the conveyor belt and close to the lower surface of the conveyor belt, the silicon steel sheet 5 is attached to the outer ring surface of the conveyor belt with the help of the magnetically conductive plate 2 and is moved from the discharge end 3 of the bevel cutting mechanism to the top of the sorting table 4 with the help of the conveyor belt, and also includes a unloading mechanism, the unloading mechanism includes an unloading push plate 6 and an unloading telescopic cylinder 7, the conveyor belt and the magnetically conductive plate 2 are provided with an unloading gap for the unloading push plate 6 to pass through, the unloading push plate 6 pushes the silicon steel sheet 5 along the gap to separate from the conveyor belt with the help of the unloading telescopic cylinder 7.

[0020] The current unloading method of the electromagnetic conveyor belt requires frequent power off and on of the electromagnetic conveyor belt, which causes a sudden increase in the power consumption of the electromagnetic conveyor belt and increases the production cost. At the same time, only one group of silicon steel sheets 5 can be transferred at a time, and the transfer efficiency is low.

[0021] Therefore, the utility model is additionally provided with a feeding mechanism and a feeding gap is provided on the conveyor belt on the magnetic conductive plate 2. When in use, the silicon steel sheet 5 at the discharge end 3 of the bevel cutting mechanism is adsorbed on the conveyor belt with the help of the magnetic conductive plate 2 and moves with the help of the conveyor belt. When the silicon steel sheet 5 moves to the top of the sorting table 4, the feeding push plate 6 is extended along the gap with the help of the feeding telescopic cylinder 7 to push the silicon steel sheet 5 away from the magnetic conductive plate 2. When the feeding push plate 6 is extended to the farthest end, the gravity of the silicon steel sheet 5 is greater than the suction force of the magnetic conductive plate 2 on the silicon steel sheet 5. At this time, the silicon steel sheet 5 falls onto the sorting table 4, and subsequent silicon steel sheets 5 repeat the above operation and form a stack between the silicon steel sheets 5. Finally, the staff can simply sort the stacked silicon steel sheets 5. The magnetic conductive plate 2 can be a permanent magnet or an electromagnet. The electromagnet can be continuously energized without powering off, which reduces the energy consumption of the unloading process. At the same time, the entire unloading and sorting process is carried out continuously, and multiple spaced silicon steel sheets 5 can be placed on the conveyor belt at the same time, and unloaded in sequence, which improves the material transfer efficiency.

[0022] like Figure 3As shown, the conveyor belt includes symmetrically arranged driving rollers 8 and two rows of driving belt bodies 9 rotated by means of the driving rollers 8. A material unloading gap for the material unloading push plate 6 to pass through is arranged between the driving belt bodies 9. The width of the material unloading gap is smaller than the width of the silicon steel sheet 5. The material unloading gap is formed by two rows of spaced-apart driving belt bodies 9 for the material unloading push plate 6 to pass through. At the same time, the gap width should not be too large, and it is necessary to ensure that the suction force of the magnetic conductive plate 2 on the silicon steel sheet 5 is greater than the gravity of the silicon steel sheet 5.

[0023] like Figure 1-3 As shown, the conveyor belt also includes an elastic belt body 10 and a guide roller 11. The elastic belt body 10 is located in the unloading gap, and the guide roller 11 is located above the driving roller 8. The elastic belt body 10 is wrapped around the outside of the conveyor belt and the unloading mechanism with the help of the guide roller 11 and the driving roller 8. The unloading push plate 6 pushes the silicon steel sheet 5 away from the conveyor belt with the help of the lower surface of the elastic belt body 10. When the unloading push plate 6 pushes the silicon steel sheet 5, the silicon steel sheet 5 is in a moving state, and a relative movement is generated between the two. Therefore, the edge of the unloading push plate 6 is prone to scratches on the surface of the silicon steel sheet 5. In order to avoid the above-mentioned problems, the utility model is provided with an elastic belt 10. When the front end of the silicon steel sheet 5 passes through the limit shaft 12 but does not reach the vertical surface where the material unloading push plate 6 is located, the material unloading push plate 6 extends and pushes the elastic belt 10 to form a downwardly protruding slope. At this time, the front end of the silicon steel sheet 5 is lifted up with the deformation of the elastic belt 10, and then continues to move along the slope formed by the elastic belt 10 as the driving belt 9 tilts, and finally leaves the magnetic field range of the magnetic conductive plate 2 and falls onto the sorting table 4. Since the rotation speed of the elastic belt 10 is similar to that of the driving belt 9, scratches on the surface of the silicon steel sheet 5 can be avoided. By limiting the timing of pushing out the material unloading push plate 6, it can be ensured that the end of the silicon steel sheet 5 is lifted up and continues to slide along the slope formed by the elastic belt 10, thereby avoiding the end of the silicon steel sheet 5 from facing the slope formed by the elastic belt 10 and scratching the surface of the elastic belt 10.

[0024] like Figure 2-3 As shown, the conveyor belt also includes a limiting shaft 12, and the limiting shaft 12 is symmetrically arranged on both sides of the unloading push plate 6. The elastic belt body 10 is cantilevered above the plane where the driving belt body 9 is located with the help of the limiting shaft 12, and the lower side busbar of the limiting shaft 12 is located above the plane where the driving belt body 9 is located. By setting the limiting shaft 12, the elastic belt body 10 is only located near the push plate to form a slope. At the same time, the lower side busbar of the limiting shaft 12 is located above the plane where the lower surface of the driving belt body 9 is located, so as to avoid the limiting shaft 12 itself hindering the movement of the silicon steel sheet 5.

[0025] like Figure 1-2As shown, the unloading mechanism is arranged in multiple groups at equal intervals along the feeding direction. When the unloading push plate 6 is extended by the unloading telescopic cylinder 7, the angle a between the elastic belt body 10 and the driving belt body 9 between the limiting shaft 12 and the side of the unloading push plate 6 is 20-30°. By setting up multiple groups of unloading mechanisms, multiple groups of stacked silicon steel sheets 5 can be formed on the surface of the sorting table 4, so that the staff can sort out multiple groups of stacked silicon steel sheets 5 at one time and store them for standby use, thereby increasing the sorting efficiency. At the same time, by adjusting the spacing between adjacent limiting shafts 12, the angle of the angle a is controlled to avoid the angle a being too large, which will cause the elastic monomer to form a slope that is not smooth enough.

[0026] like Figure 1 As shown, the height difference between the discharge end 3 of the bevel cutting mechanism and the lower surface of the conveyor belt is 1-2 cm, and the height difference between the sorting table 4 and the lower surface of the conveyor belt is 15-30 cm. In order to ensure that the magnetic conductive plate 2 can adsorb the silicon steel sheet 5, the discharge end 3 of the bevel cutting mechanism is close to the lower surface of the conveyor belt.
