Description

Technical Field

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

[0002] The silicon steel sheet shearing and feeding device is a piece of equipment that uses automation technology to shear and feed silicon steel sheets. The feeding mechanism stably and efficiently transports the silicon steel sheets to the shearing position. It is a device that integrates high precision, high efficiency and automation, and is of great significance in modern electrical equipment manufacturing.

[0003] In some existing silicon steel sheet shearing and feeding devices, to reduce the risk of excessive tension causing extrusion deformation and wear between the silicon steel sheet and the conveying device during the rotation and gradual discharge of the silicon steel sheet, a sufficient gap is usually set between the feeding device and the shearing device. This ensures that the silicon steel sheet is in a loose state when discharged from the output end of the feeding device, allowing it to have a certain amount of sag. As the conveying device carries the silicon steel sheet, the portion of the silicon steel sheet with sag will have a large amplitude of swaying. Due to the relatively flat structure on both sides of the silicon steel sheet, it is directly exposed to the external environment. The swaying silicon steel sheet is very likely to scratch the operators, posing a high safety hazard and causing great inconvenience. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a silicon steel sheet shearing and feeding device. This addresses the issue raised in the background section where, during the rotation and gradual discharge of silicon steel sheets, some existing silicon steel sheet shearing and feeding devices typically have a sufficient gap between the feeding device and the shearing device to reduce the risk of excessive tension causing compression deformation and wear between the silicon steel sheet and the conveying device. This gap ensures the silicon steel sheet is loosely distributed at the output end of the feeding device, allowing it to sag. However, this results in significant swaying of the sag portion of the silicon steel sheet during transport. Due to the relatively flat structure of the silicon steel sheet's sides, it is directly exposed to the external environment, making it highly susceptible to scratching workers, posing a significant safety hazard and causing considerable inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon steel sheet shearing and feeding device, comprising a main body mechanism and a limiting mechanism disposed on one side of the main body mechanism to limit the swaying amplitude of a silicon steel sheet with a drooping amount when conveyed by a conveying device. The limiting mechanism includes a plurality of positioning screws threadedly connected to both sides of a top frame and symmetrically arranged. Each positioning screw has an adapter plate movably connected to its outer side through a limiting hole. A side arm is fixedly connected to one side of the adapter plate. A front abutment screw is slidably connected to the inner side of the side arm. A limiting ring is threadedly connected to the outer side of one end of the front abutment screw. A side frame is rotatably connected to the outer side of the other end of the front abutment screw. A spring is movably connected to the outer side of the front abutment screw. The spring is located between the side arm and the side frame. A limiting roller is rotatably connected to the inner side of the side frame. A plurality of limiting rollers are symmetrically arranged.

[0006] Preferably, the main body mechanism includes a base plate, a column fixedly connected to the top of the base plate, several legs symmetrically arranged on the outer side of the column, a base plate fixedly connected to the bottom of the legs, a top frame fixedly connected to the top of the column, a motor fixedly connected to the top of the top frame, two motors symmetrically arranged, a drive gear fixedly connected to the output end of the motor, a synchronous belt drivingly connected to the outer side of the drive gear, a feeding roller drivingly connected to the bottom of the synchronous belt, and a top frame rotatably connected to the outer side of one end of the feeding roller.

[0007] Preferably, the limiting hole has an arc-shaped structure, and a positioning screw is movably connected to the inner side of the limiting hole.

[0008] Preferably, an angle gauge is fixedly connected to one side of the adapter plate, and the angle gauge is located on one side of the positioning screw.

[0009] Preferably, a washer is movably connected to the outer side of one end of the positioning screw, and the washer is located on one side of the limiting hole.

[0010] Preferably, a sliding rod is fixedly connected to one side of the side frame, and two sliding rods are symmetrically arranged. A side arm is slidably connected to the outer side of the sliding rod.

[0011] Preferably, a knob is fixedly connected to one side of the limiting ring, and several knobs are symmetrically arranged. A front abutment screw is threadedly connected to the inner side of the limiting ring.

[0012] Preferably, a buffer pad is fixedly connected to the outer side of the limiting roller, the buffer pad is made of flexible material, and side frames are rotatably connected to the outer sides of both ends of the limiting roller.

[0013] Compared with the prior art, the present invention provides a silicon steel sheet shearing and feeding device, which has the following advantages:

[0014] 1. This utility model uses a limiting roller to install the silicon steel sheet roll on the outside of the feeding roller. Then, based on the position of the loosely drooping silicon steel sheet, the positioning screws are rotated counterclockwise to loosen them. This, combined with the arc-shaped limiting hole, rotates the adapter plate until the front abutment screw and one end of the side frame on the inside of the side arm are at a suitable angle. Then, the positioning screws are rotated clockwise to increase the pressure of the gasket on the outer wall of the adapter plate, thus fixing the angle of the adapter plate. Simultaneously, the gasket ensures the stability of the positioning screw position. Then, the knob is directly squeezed and the limiting ring is rotated counterclockwise to adjust the limiting ring to a position away from the side arm, releasing the restriction on the front abutment screw. The front abutment screw slides inside the side arm, moving horizontally until the buffer pad on the outside of the limiting roller contacts the drooping, rolled silicon steel sheet. The limiting ring is then rotated counterclockwise to loosen the front abutment screw. The positioning ring fully contacts the side arm, limiting the sliding ability of the front abutment screw in one direction. Finally, the motor is turned on to drive the drive gear to rotate, which in turn drives the feeding roller to rotate via the synchronous belt, discharging the wound silicon steel sheet cylinder. During the process of conveying the silicon steel sheet by the rear conveyor, when the silicon steel sheet in the drooping and bent state shakes under force, it will first impact the limiting roller. The limiting roller rotates under force, and the conveying continues. At the same time, the impact force acting on one side of the limiting roller will cause the side frame and the front abutment screw to retract, and compress the spring to contract and store energy. When the silicon steel sheet is not in contact with the limiting roller, the pressure on the spring disappears, and it opens, causing the side frame and the front abutment screw to reset. This can effectively reduce the shaking amplitude caused by the conveying device during the feeding process, thereby reducing the possibility of the relatively sharp edge of the silicon steel sheet scratching the on-site workers and ensuring the safety of the operation.

[0015] 2. By setting an angle gauge, this utility model compares the angle gauge with the positioning screw that is relatively fixed in position during the synchronous rotation of the angle gauge with the adapter plate, which can effectively mark the angle value of the adapter plate and display the current angle position of the adapter plate and the side arm.

[0016] 3. By setting a sliding rod, this utility model can effectively protect the swing amplitude generated by the side frame during the force and sliding process, and ensure the stability of the side frame position.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4This utility model provides a technical solution: a silicon steel sheet shearing and feeding device, including a main body mechanism 1 and a limiting mechanism 2 disposed on one side of the main body mechanism 1 to limit the swaying amplitude of the silicon steel sheet with a drooping amount when it is conveyed by a conveying device. The limiting mechanism 2 includes a plurality of positioning screws 201 threadedly connected to both sides of the top frame 104. Each positioning screw 201 has an adapter plate 203 movably connected to its outer side through a limiting hole 202. A side arm 204 is fixedly connected to one side of the adapter plate 203. A front abutment screw 205 is slidably connected to the inner side of the side arm 204. A limiting ring 206 is threadedly connected to the outer side of one end of the front abutment screw 205. A side frame 208 is rotatably connected to the outer side of the other end of the front abutment screw 205. A limiting ring 206 is movably connected to the outer side of the front abutment screw 205. Spring 207 is located between side arm 204 and side frame 208. A limiting roller 209 is rotatably connected to the inner side of side frame 208. Several limiting rollers 209 are symmetrically arranged. The silicon steel sheet roll is installed on the outer side of the feeding roller 108. Then, based on the position of the loosely drooping silicon steel sheet, each positioning screw 201 is rotated counterclockwise and loosened. This, combined with the arc-shaped limiting hole 202, rotates the adapter plate 203 until the front abutment screw 205 on the inner side of side arm 204 and one end of the side frame 208 are at a suitable angle. Then, the positioning screw 201 is rotated clockwise, increasing the pressure of the gasket 5 on the outer wall of the adapter plate 203, thereby fixing the angle position of the adapter plate 203. Simultaneously, the gasket 5 ensures the positioning screw 201 is securely positioned. To ensure the stability of position 01, directly pinch knob 7 and rotate the limiting ring 206 counterclockwise to adjust the limiting ring 206 to a position away from the side arm 204, releasing the restriction on the position of the front abutment screw 205. Slide the front abutment screw 205 within the side arm 204, moving it horizontally until the buffer pad 3 outside the limiting roller 209 contacts the drooping and curled silicon steel sheet. Rotate the limiting ring 206 in the opposite direction to ensure that one side of the limiting ring 206 fully contacts the side arm 204, restricting the sliding ability of the front abutment screw 205 in one direction. Finally, turn on the motor 105 to drive the drive gear 106 to rotate, which in turn drives the feeding roller 108 to rotate via the synchronous belt 107, discharging the wound silicon steel sheet cylinder, which is then conveyed from the rear end. During the conveying process of silicon steel sheets, when the drooping and bent portion of the silicon steel sheet vibrates under force, it will first impact the limiting roller 209. The limiting roller 209 rotates under the force, and the conveying continues. At the same time, the impact force acting on one side of the limiting roller 209 will cause the side frame 208 and the front abutment screw 205 to retract, and compress the spring 207 to contract and store energy. When the silicon steel sheet is not in contact with the limiting roller 209, the pressure on the spring 207 disappears, and it opens, causing the side frame 208 and the front abutment screw 205 to reset. This can effectively reduce the vibration amplitude caused by the conveying device during the feeding process, thereby reducing the possibility of the relatively sharp edge of the silicon steel sheet scratching the on-site workers and ensuring the safety of the operation.

[0026] In this utility model, preferably, the main body mechanism 1 includes a base plate 101, a column 102 fixedly connected to the top of the base plate 101, a plurality of legs 103 symmetrically arranged on the outer side of the column 102, the base plate 101 fixedly connected to the bottom of the legs 103, a top frame 104 fixedly connected to the top of the column 102, a motor 105 fixedly connected to the top of the top frame 104, two motors 105 symmetrically arranged, a drive gear 106 fixedly connected to the output end of the motor 105, a synchronous belt 107 drivingly connected to the outer side of the drive gear 106, a feeding roller 108 drivingly connected to the bottom of the synchronous belt 107, and a top frame 104 rotatably connected to the outer side of one end of the feeding roller 108. The wound silicon steel sheet roll is installed on the outer side of the feeding roller 108, and then the motor 105 is turned on to drive the drive gear 106 to rotate. Through the transmission of the synchronous belt 107, the feeding roller 108 is driven to rotate at a uniform speed to release the silicon steel sheet.

[0027] In this utility model, preferably, the limiting hole 202 has an arc-shaped structure, and a positioning screw 201 is movably connected to the inner side of the limiting hole 202, which can adjust the overall angle position of the limiting mechanism 2 according to actual needs.

[0028] In this utility model, preferably, an angle ruler 4 is fixedly connected to one side of the adapter plate 203. The angle ruler 4 is located on one side of the positioning screw 201. During the synchronous rotation of the angle ruler 4 with the adapter plate 203, it is compared with the positioning screw 201 which is relatively fixed in position, so as to effectively identify the angle value of the adapter plate 203 and display the current angle position of the adapter plate 203 and the side arm 204.

[0029] In this utility model, preferably, a washer 5 is movably connected to the outer side of one end of the positioning screw 201. The washer 5 is located on one side of the limiting hole 202, which can effectively reduce the loosening of the positioning screw 201 during long-term use and ensure the stability of the angular position of the adapter plate 203.

[0030] In this utility model, preferably, a sliding rod 6 is fixedly connected to one side of the side frame 208, and two sliding rods 6 are symmetrically arranged. A side arm 204 is slidably connected to the outside of the sliding rod 6, which can effectively ensure the swing amplitude generated by the side frame 208 during the force and sliding process, and ensure the stability of the position of the side frame 208.

[0031] In this utility model, preferably, a knob 7 is fixedly connected to one side of the limiting ring 206, and several knobs 7 are symmetrically arranged. A front abutment screw 205 is threadedly connected to the inner side of the limiting ring 206, which can effectively and conveniently allow personnel to directly pinch and rotate the limiting ring 206 without the aid of external tools, thereby improving the human-machine efficiency of the device.

[0032] In this utility model, preferably, a buffer pad 3 is fixedly connected to the outer side of the limiting roller 209. The buffer pad 3 is made of flexible material. Side frames 208 are rotatably connected to the outer sides of both ends of the limiting roller 209, which can effectively reduce the degree of wear on the surface of the silicon steel sheet during the contact process.

[0033] The working principle and usage process of this utility model are as follows: In use, the silicon steel sheet raw material roll is installed on the outside of the feeding roller 108. Then, based on the position of the loosely drooping silicon steel sheet, each positioning screw 201 is rotated counterclockwise and loosened. This, combined with the arc-shaped limiting hole 202, rotates the adapter plate 203 until the front abutment screw 205 on the inner side of the side arm 204 and one end of the side frame 208 are at a suitable angle. Then, the positioning screw 201 is rotated clockwise to increase the pressure of the gasket 5 on the outer wall of the adapter plate 203, thereby fixing the sheet in place. The angle position of the adapter plate 203, along with the action of the shim 5, ensures the stability of the position of the positioning screw 201. Then, directly pinch the knob 7 and rotate the limiting ring 206 counterclockwise to adjust the limiting ring 206 to a position away from the side arm 204, releasing the restriction on the position of the front abutment screw 205. Slide the front abutment screw 205 within the side arm 204, so that the front abutment screw 205 moves horizontally to the position where the buffer pad 3 outside the limiting roller 209 contacts the drooping and curled silicon steel sheet. Rotate the limiting ring 205 in the opposite direction. The positioning ring 206 ensures that one side of the limiting ring 206 fully contacts the side arm 204, restricting the sliding ability of the front abutment screw 205 in one direction. Finally, the motor 105 is turned on to drive the drive gear 106 to rotate, which in turn drives the feeding roller 108 to rotate via the synchronous belt 107, discharging the wound silicon steel sheet cylinder. During the process of conveying the silicon steel sheets by the rear conveying equipment, when the silicon steel sheet portion is in a drooping and bent state and shakes under force, it will first impact the limiting roller 209. The limiting roller 209 rotates under the force, thus continuing the conveying process. Simultaneously, the impact force acting on one side of the limiting roller 209 will cause the side frame 208 and the front abutment screw 205 to retract, and compress the spring 207 to contract and store energy. When the silicon steel sheet is in a non-contact state with the limiting roller 209, the pressure on the spring 207 disappears, and it immediately opens, causing the side frame 208 and the front abutment screw 205 to reset. This can effectively reduce the shaking amplitude caused by the transmission of the conveying device during the feeding process, thereby reducing the occurrence of the relatively sharp edge of the silicon steel sheet scratching the on-site workers and ensuring the safety of the operation.

[0034] 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.
