Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet processing technology, specifically to a silicon steel sheet processing feeding device. Background Technology

[0002] Motor laminations are parts that are produced by pressing metal sheets of a specific thickness using dies, resulting in parts with the required geometric shapes and dimensions. They are mainly used to form the magnetic circuit parts of the stator and rotor of motors. Silicon steel sheets with low carbon content, good magnetic permeability, and a high strength-to-weight ratio are typically selected. Silicon steel sheets are available in cold-rolled and hot-rolled varieties. Cold-rolled silicon steel sheets are further divided into oriented and non-oriented types, with non-oriented cold-rolled silicon steel sheets being more commonly used in motors.

[0003] Before stamping, silicon steel sheets need to be transported using a feeding device. However, existing feeding devices are not convenient for limiting the width of the silicon steel sheets during transport, which can easily cause the silicon steel sheets to become skewed during transport, affecting the subsequent stamping effect.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the present invention provides a feeding device for silicon steel sheet processing, which has the following advantages:

[0030] This feeding device offers the advantage of easy guidance and positioning. Motor 1 is started in advance, driving a bidirectional lead screw to rotate. The support frame threaded onto the lead screw causes the bottom guide plates to move closer together, ensuring the guide plate spacing is slightly larger than the width of the silicon steel sheet. The silicon steel sheet is then placed on the conveyor rollers, which transport it to the guide plates. The guide plates then position the silicon steel sheet in the middle of the conveyor rollers, preventing it from tilting and facilitating subsequent processing. Because the guide plate spacing is adjustable, the device can easily guide and position silicon steel sheets of different widths, thus improving its applicability. This solves the problem of existing feeding devices being unable to easily position the silicon steel sheet according to its width, leading to tilting during transport and affecting subsequent stamping results.

[0041] 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.

[0042] Example 1

[0043] See Figure 1-5 A feeding device for processing silicon steel sheets includes a main assembly 1, which includes: a side plate 11, with a conveying roller 12 symmetrically and rotatably connected to its center; a positioning and guiding assembly 2 is provided on the side plate 11 and the conveying roller 12, the positioning and guiding assembly 2 including: a bracket 21 fixedly connected to the top of the side plate 11; a bidirectional lead screw 22 rotatably connected to the bottom of the bracket 21; a support frame 23 symmetrically and threadedly connected to the bidirectional lead screw 22; a guide plate 24 symmetrically and fixedly connected to the bottom of the support frame 23, the bottom of the guide plate 24 being slidably connected to the top of the conveying roller 12; and a motor 25 disposed on the outer wall of the bracket 21, the output shaft of the motor 25 being fixedly connected to one end of the bidirectional lead screw 22. A top plate 26 is fixedly connected to the top of the motor 25, and rollers 27 are symmetrically and fixedly connected to the bottom of the top plate 26. A distance-fixing component 3 is provided on the side plate 11. The distance-fixing component 3 includes: a second bracket 31, with the side plate 11 fixedly connected to its top; a second motor 32, disposed on the top of the second bracket 31; a controller 321, disposed on the top of the second bracket 31; a reciprocating screw 33, rotatably connected to the bottom of the second bracket 31, with the top of the reciprocating screw 33 fixedly connected to the bottom output shaft of the second motor 32; a baffle 34, threadedly connected to the outside of the reciprocating screw 33; and a slide rod 35, fixedly connected to the top of the baffle 34, with the top of the slide rod 35 passing through and sliding. A photoelectric sensor 36 is movably connected to the second bracket 31; a photoelectric sensor 36 is disposed on the inner wall of the side plate 11, the photoelectric sensor 36 is located on the side of the baffle 34 near the guide plate 24, and the photoelectric sensor 36 is electrically connected to the second motor 32 through the controller 321; a photoelectric sensor 37 is disposed on the inner wall of the side plate 11, the photoelectric sensor 36 is located on the side of the baffle 34 away from the guide plate 24, and the photoelectric sensor 37 is electrically connected to the second motor 32 through the controller 321.

[0044] In operation, the operator starts motor 25 in advance. Motor 25 drives the bidirectional lead screw 22 to rotate. The support frame 23 threaded onto the bidirectional lead screw 22 causes the bottom guide plates 24 to move closer together, so that the distance between the guide plates 24 is slightly larger than the width of the silicon steel sheet. The silicon steel sheet is then placed on the conveyor roller 12, which transports the silicon steel sheet to the guide plate 24. The guide plate 24 limits the silicon steel sheet in the middle of the conveyor roller 12 to prevent it from tilting, thus facilitating subsequent processing. Since the distance between the guide plates 24 is adjustable, the device can easily limit and guide silicon steel sheets of different widths, thereby improving the applicability of the device. The top plate 26 set on the top of the guide plate 24 is used to support the roller 27. The roller 27 contacts the edge of the silicon steel sheet during feeding, thereby reducing the friction of the silicon steel sheet when passing through the guide plate 24 and improving the feeding efficiency of the silicon steel sheet.

[0045] When the silicon steel sheets are guided to the area below the second support 31, the spacing component 3 fixes the spacing of the silicon steel sheets being fed, thus facilitating subsequent processing. When the first silicon steel sheet moves past the first photoelectric sensor 36, the first photoelectric sensor 36 is triggered, transmitting a signal to the controller 321. The controller 321 records the position information at this time as the reference position for the previous silicon steel sheet. When the second silicon steel sheet passes the first photoelectric sensor 36, the first photoelectric sensor 36 controls the second motor 32 to start via the controller 321. The second motor 32 drives the reciprocating screw 33 to rotate, and the baffle 34 moves downward to the bottom, blocking the silicon steel sheet from advancing. When the first silicon steel sheet passes the second photoelectric sensor 37 behind it, the second photoelectric sensor 37 is restarted via the controller 321, and the baffle 34 rises along the reciprocating screw 33. At this time, the spacing between the two silicon steel sheets is fixed. Subsequent silicon steel sheets are fed in the same manner, thus facilitating subsequent processing. When the baffle 34 moves up and down, the top slide bar 35 slides up and down along the bracket 31, which guides the baffle 34.

[0046] The aforementioned photoelectric sensor 36 and photoelectric sensor 37 are existing technologies. The transmitting and receiving ends of photoelectric sensor 36 and photoelectric sensor 37 are placed opposite each other. When an object blocks the light emitted from the transmitting end, preventing it from reaching the receiving end, the receiving end detects the change in light intensity, thereby generating a change in electrical signal, which is used to detect the presence or positional change of the object. The specific structure will not be described in detail here.

[0047] Example 2

[0048] An auxiliary function has been added based on Embodiment 1.

[0049] See Figure 1-5A protective pad 4 is provided on the outer wall of the roller 27. A telescopic sleeve 5 is fixedly connected between the bracket 31 and the baffle 34, and the telescopic sleeve 5 is fitted over the reciprocating screw 33. Multiple slide rods 35 are symmetrically arranged, with at least two arranged symmetrically on both sides of the reciprocating screw 33.

[0050] The surface of silicon steel sheets typically needs to be kept smooth and flat to ensure their electromagnetic properties and subsequent processing quality. The protective pad 4 prevents the roller 27 from directly contacting the silicon steel sheet, preventing scratches, wear, or indentations on the surface of the silicon steel sheet due to friction or collision during transport, thus ensuring the surface quality of the silicon steel sheet. When the baffle 34 moves upward, the telescopic sleeve 5 at the top of the baffle 34 retracts; when the baffle 34 moves downward, the telescopic sleeve 5 extends, shielding the reciprocating lead screw 33 and preventing accidental contact by personnel. The symmetrically arranged sliding rods 35 on both sides of the reciprocating lead screw 33 ensure a more even distribution of support force on the baffle 34 during movement.

[0051] 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.
