Abstract
Description
Technical Field
[0001] This application belongs to the field of silicon steel sheet processing technology, specifically relating to a transformer core silicon steel sheet cutting device. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core. The iron core is the main magnetic circuit part of the transformer, and it is usually made of laminated silicon steel sheets.
[0003] In existing technologies, silicon steel sheets are typically stored in rolls and require a cutting device to cut them to the required dimensions. Specifically, common cutting devices include a cutter that moves horizontally or vertically. The silicon steel sheet is manually guided onto the cutter's path, where it is split in two. The front section of the cut-off sheet is then manually retrieved, and the rear section is guided back onto the cutter's path.
[0004] The inventors discovered that the process of manually pulling silicon steel sheets can result in cuts to the hands from the cutting tool, reducing the safety of silicon steel sheet processing. At the same time, the process of manually retrieving and pulling silicon steel sheets again consumes a lot of time, reducing the efficiency of silicon steel sheet processing. Utility Model Content
[0005] This application provides a transformer core silicon steel sheet cutting device, which is designed to automatically position and cut silicon steel sheets, and can move the cut silicon steel sheets to the outside to facilitate subsequent recycling and ensure the processing efficiency of silicon steel sheets.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] A transformer core silicon steel sheet cutting device is provided, comprising:
[0008] The base has two side plates extending upward and facing each other; between the two side plates are two rotating shafts arranged parallel in the horizontal direction, and a conveyor belt sleeved on the outer periphery of the two rotating shafts;
[0009] A rotating roller, disposed on the upper side of the conveyor belt, has its axial direction parallel to the axial direction of the rotating shaft, and is driven by a rotational drive component; the rotating roller is fixedly connected to a plurality of pressure plates spaced apart along its circumference, each pressure plate extending radially outward along the rotating roller, such that one or two pressure plates abut against silicon steel sheets on the conveyor belt; and
[0010] The cutter is slidably disposed on the upper side of the conveyor belt, and its sliding direction is parallel to the axial direction of the rotating shaft. The cutter is driven by a linear drive component. When the two pressure plates abut against the silicon steel sheet, the cutter is located between the two pressure plates. When the rotating roller rotates and at least one of the pressure plates abuts against the conveyor belt, the conveyor belt moves relative to the base.
[0011] In one possible implementation, one of the side plates has a guide hole extending axially along the pivot, and the cutter is slidably inserted into the guide hole.
[0012] In one possible implementation, another of the side plates has a slot suitable for inserting the cutter.
[0013] In one possible implementation, the linear drive component is a linear cylinder fixedly disposed on the outer side of the side plate and drivenly connected to one end of the cutter located outside the guide hole.
[0014] In one possible implementation, the rotation drive component is a rotating motor fixedly mounted on one of the side plates and coaxially connected to the rotating roller.
[0015] In one possible implementation, a support plate is further provided between the two side plates, and the two sides of the support plate are respectively fixedly connected to the two side plates;
[0016] The support plate is located inside the conveyor belt, and the upper side of the support plate abuts against the inner side of the conveyor belt to limit the downward concavity of the conveyor belt; and the pressure plate is made of an elastic material to be adapted to undergo elastic deformation when it abuts against the support plate by the conveyor belt.
[0017] In one possible implementation, the transformer core silicon steel sheet cutting device further includes:
[0018] The feeding component is fixedly mounted on the base to support the rolled silicon steel sheets, and to make the axial direction of the silicon steel sheet roll parallel to the axial direction of the rotating shaft.
[0019] In one possible implementation, the feeding component includes:
[0020] A fixing plate, fixedly connected to one of the side plates; the fixing plate has a take-up shaft extending outward in a horizontal direction; and
[0021] A sliding plate is slidably connected to another side plate along the arrangement direction of the two side plates, and has a through hole suitable for the extension end of the winding shaft to pass through.
[0022] The extended end of the winding shaft is threadedly connected to a threaded sleeve for abutting against the outer side of the sliding plate. The winding shaft is used to accommodate silicon steel sheets in a coiled state.
[0023] In one possible implementation, a fixed shaft is fixedly connected between the two side plates, the axis of the fixed shaft being parallel to the axis of the rotating shaft, and a roller for contacting the upward-facing side of the silicon steel sheet is sleeved on the fixed shaft so that the silicon steel sheet is in contact with the upper side of the conveyor belt.
[0024] In one possible implementation, each of the rotating shafts has a plurality of protruding teeth spaced apart along its circumference on its outer peripheral surface, and the conveyor belt has a plurality of tooth grooves spaced apart along its length and adapted for the protruding teeth to be inserted into its inner peripheral surface.
[0025] In this embodiment, by placing the silicon steel sheet on the upper side of the conveyor belt and applying downward pressure to the silicon steel sheet, the silicon steel sheet can move synchronously with the translational movement of the conveyor belt. Based on this, by rotating the drive component, the roller can be rotated until two of the pressure plates abut against the silicon steel sheet, so that the cutting position of the silicon steel sheet is fixed at the front side of the cutter. By driving the cutter to move through the linear drive component, the silicon steel sheet can be cut.
[0026] After the silicon steel sheet is cut, the rotating drive component drives the rotating roller to rotate, which makes the silicon steel sheet move horizontally. The cut silicon steel sheet will move to the outside in the horizontal direction under the horizontal action of the conveyor belt for easy recycling.
[0027] The transformer core silicon steel sheet cutting device provided in this embodiment, compared with the prior art, can automatically position and cut silicon steel sheets, and can translate the cut silicon steel sheets to the outside to facilitate subsequent recycling and ensure the processing efficiency of silicon steel sheets.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0044] Please refer to the following: Figures 1 to 10 The transformer core silicon steel sheet cutting device provided in this application will now be described. The transformer core silicon steel sheet cutting device proposed in this application includes a base 1, a rotating roller 2, and a cutter 3.
[0045] The base 1 adopts a flat plate structure extending horizontally, and has two side plates 11 extending upward and facing each other. In this embodiment, there are two rotating shafts 12 arranged in parallel horizontally between the two side plates 11, and a conveyor belt 13 sleeved on the outer periphery of the two rotating shafts 12.
[0046] The rotating roller 2 is positioned on the upper side of the conveyor belt 13, with its axial direction parallel to that of the rotating shaft 12. The rotating roller 2 is connected to a drive component 21 for rotating it. Multiple pressure plates 22 are fixedly connected to the rotating roller 2 and spaced circumferentially. Each pressure plate 22 extends radially outwards along the rotating roller 2, such that one or two pressure plates 22 abut against the silicon steel sheet 100 on the conveyor belt 13. Specifically, during the rotation of the rotating roller 2, there are only two states: a single pressure plate 22 abutting against the silicon steel sheet 100 (or the conveyor belt 13), and two pressure plates 22 simultaneously abutting against the silicon steel sheet 100 (or the conveyor belt 13).
[0047] The cutter 3 is slidably disposed on the upper side of the conveyor belt 13, and its sliding direction is parallel to the axis of the rotating shaft 12. The cutter 3 is also connected to a linear drive component 31 for driving it to move in a preset direction.
[0048] When the two pressure plates 22 abut against the silicon steel sheet 100, the cutter 3 is positioned between the two pressure plates 22 to facilitate cutting the silicon steel sheet 100; and since both sides of the silicon steel sheet 100 at the cutting position are pressed by the pressure plates 22, the silicon steel sheet 100 will not move under the action of the cutter 3.
[0049] When the roller 2 rotates and at least one pressure plate 22 abuts against the conveyor belt 13, the conveyor belt 13 is able to translate relative to the base 1 under the relevant force.
[0050] In this embodiment, by placing the silicon steel sheet 100 on the upper side of the conveyor belt 13 and applying downward pressure to the silicon steel sheet 100, the silicon steel sheet 100 can move synchronously with the translational movement of the conveyor belt 13. Based on this, by rotating the drive component 21, the roller 2 can be rotated until two of the pressure plates 22 abut against the silicon steel sheet 100, so that the cutting position of the silicon steel sheet 100 is fixed at the front side of the cutter 3. By driving the cutter 3 to move through the linear drive component 31, the silicon steel sheet 100 can be cut.
[0051] After the silicon steel sheet 100 is cut, the rotating roller 2 is driven by the rotating drive component 21 to rotate, so that the silicon steel sheet 100 can be moved horizontally. The cut silicon steel sheet 100 will move to the outside in the horizontal direction under the horizontal action of the conveyor belt 13 for easy recycling.
[0052] The transformer core silicon steel sheet cutting device provided in this embodiment, compared with the prior art, can automatically position and cut the silicon steel sheet 100, and can translate the cut silicon steel sheet 100 to the outside to facilitate subsequent recycling and ensure the processing efficiency of the silicon steel sheet 100.
[0053] In some embodiments, such as Figure 1 , Figure 6 and Figure 10 As shown, one of the side plates 11 has a guide hole 111 that runs through the axis of the rotating shaft 12. The cutter 3 is slidably inserted into the guide hole 111 to realize the sliding connection between the cutter 3 and the base 1, while ensuring that the cutter 3 is in the center position between the two pressure plates 22 that are connected to the silicon steel sheet 100 on the conveyor belt 13.
[0054] In some embodiments, such as Figure 10 As shown, another side plate 11 has a slot 112 suitable for inserting the cutter 3 to ensure that the end of the cutter 3 passes through the silicon steel sheet 100, thereby achieving the technical purpose of cutting the silicon steel sheet 100.
[0055] In some embodiments, such as Figure 6 As shown, the linear drive component 31 is a linear cylinder that is fixedly installed on the outer side of the side plate 11 and is connected to the end of the cutter 3 located outside the guide hole 111. This linear cylinder can drive the cutter 3 to move in the horizontal direction.
[0056] In some embodiments, such as Figure 2 and Figure 7As shown, the rotation drive component 21 is a rotating motor that is fixedly mounted on one of the side plates 11 and coaxially connected to the rotating roller 2, so as to realize the automatic drive of the rotating roller 2.
[0057] In some embodiments, such as Figure 3 and Figure 10 As shown, there is also a support plate 4 between the two side plates 11, and the two sides of the support plate 4 are fixedly connected to the two side plates 11 respectively.
[0058] The support plate 4 is located inside the conveyor belt 13, and the upper side of the support plate 4 abuts against the inner side of the conveyor belt 13 to prevent the conveyor belt 13 from concave downward. Based on this, the aforementioned pressure plate 22 is made of an elastic material to be suitable for elastic deformation when it abuts against the support plate 4 as it passes the conveyor belt 13.
[0059] In some embodiments, such as Figure 1 As shown, the transformer core silicon steel sheet cutting device also includes a feeding component 5, which is fixedly mounted on the base 1 to support the rolled silicon steel sheet 100 and to make the axial direction of the rolled silicon steel sheet 100 parallel to the axial direction of the rotating shaft 12, thereby realizing the feeding of the silicon steel sheet 100.
[0060] In some embodiments, such as Figure 9 As shown, the feeding component 5 includes a fixed plate 51 and a sliding plate 52.
[0061] The fixing plate 51 is fixedly connected to one of the side plates 11, and its orientation is the same as that of the corresponding side plate 11. The fixing plate 51 has a winding shaft 511 extending outward in a horizontal direction, specifically extending toward the other side plate 11.
[0062] The sliding plate 52 is slidably connected to another side plate 11 along the arrangement direction of the two side plates 11, and has a through hole 521 on it suitable for the extension end of the winding shaft 511 to pass through; specifically, as the sliding plate 52 is combined with the side plate 11, the winding shaft 511 is set through this through hole 521.
[0063] In this embodiment, a threaded sleeve 512 is threadedly connected to the extended end of the take-up shaft 511. After the threaded sleeve 512 is connected to the take-up shaft 511, the threaded sleeve 512 can abut against the outer side of the sliding plate 52 to restrict the movement of the sliding plate 52 away from the fixed plate 51.
[0064] By adopting the above technical solution, the winding shaft 511 is used to accommodate the silicon steel sheet 100 in the coiled state, so as to fix the silicon steel sheet 100 in the coiled state.
[0065] In some embodiments, such as Figure 3 and Figure 10As shown, there is a fixed shaft 6 between the two side plates 11, which is fixedly connected to them. The axial direction of the fixed shaft 6 is parallel to the axial direction of the rotating shaft 12, and a roller 61 for contacting the upward side of the silicon steel sheet 100 is sleeved on the fixed shaft 6.
[0066] The roller 61 is made of rubber material. When the roller 61 comes into contact with the silicon steel sheet 100 that is about to enter the lower side of the roller 2, the roller 61 can undergo elastic deformation so that the silicon steel sheet 100 adheres to the upper side of the conveyor belt 13.
[0067] In some embodiments, such as Figure 8 As shown, each rotating shaft 12 has a plurality of protruding teeth 121 spaced apart along its circumference on its outer peripheral surface, and the conveyor belt 13 has a plurality of tooth grooves 131 spaced apart along its length direction for the protruding teeth 121 to be inserted into its inner peripheral surface.
[0068] By adopting the above technical solution, the meshing relationship between the convex tooth 121 and the tooth groove 131 can ensure the transmission effect between the conveyor belt 13 and the rotating shaft 12 and avoid slippage.
[0069] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
