Technical Field

[0001] This utility model relates to the field of silicon steel coil processing technology, specifically a feeding traction device for slitting and cutting silicon steel coils. Background Technology

[0002] Silicon steel coils are an important magnetic material used in the power and electronics industries, primarily for manufacturing the cores of various motors, generators, and transformers. The main component of silicon steel coils is a silicon-containing iron alloy, commonly known as electrical steel or silicon steel sheets. Its main components include silicon and a small amount of carbon, typically with a silicon content of 5% to 8%. This composition gives silicon steel sheets high magnetic permeability and low core loss, making them suitable for various applications in the power industry. A feeding traction device is required for slitting and cutting silicon steel coils.

[0003] The existing feeding and traction device does not have the function of adjusting the tension of the roll material. Excessive tension will cause damage to the roll material, resulting in poor stability of the roll material during the cutting process.

[0004] Therefore, this utility model provides a feeding traction device for slitting and cutting silicon steel coils to solve the above problems. Utility Model Content

[0005] This utility model provides a feeding traction device for slitting and cutting silicon steel coils, aiming to solve the problems mentioned in the background art, such as the existing feeding traction device not having the function of adjusting the tension of the coil, excessive tension leading to coil damage, and poor stability of the coil during the cutting process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding traction device for slitting and cutting silicon steel coils, comprising a base plate, wherein a conveyor belt and an adjustment structure are fixedly installed on the end face of the base plate and on the front and rear sides;

The lead screw is threadedly connected to a threaded sleeve, the upper end of which extends to the outside of the fixing plate and is fitted with a motor. A second roller is rotatably mounted on the threaded sleeve. By setting up this adjustment structure, the lead screw rotates in either the forward or reverse direction, causing the threaded sleeve to move upward or downward. The threaded sleeve, in turn, causes the second roller to move upward or downward, thereby achieving tension adjustment of the roll material. This avoids the problem of existing feeding traction devices lacking the ability to adjust the roll material tension, leading to excessive tension causing damage and poor stability during the cutting process.

[0008] Preferably, the conveyor belt is equipped with a separation structure;

[0009] The separation structure includes a support plate fixedly installed on the front side of the conveyor belt. A first guide plate and a second guide plate are symmetrically installed on the end face of the support plate. The ends of the first guide plate and the second guide plate near the conveyor belt are inclined portions.

[0010] Preferably, a fixed shaft is rotatably connected to the inner wall of the first roller, and the two ends of the fixed shaft are connected to two fixed plates, and the motor is fixedly connected to the end face of the fixed plate.

The displacement structure includes an extension fixedly installed on the first guide plate and the second guide plate. A T-shaped block that is slidably connected to the through groove is installed at the bottom of the extension. The T-shaped block is connected to a bolt through a threaded hole.

[0015] Beneficial effects: By setting up an adjustment structure, using the first roller, lead screw, threaded sleeve, and second roller in combination, the lead screw rotates in the forward or reverse direction, the lead screw moves the threaded sleeve up or down, and the threaded sleeve moves the second roller up or down, thereby realizing the adjustment of the coil tension.

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] This embodiment provides a feeding traction device for slitting and cutting silicon steel coils, such as... Figure 1-6 As shown, the feeding traction device includes a base plate 1, and a conveyor belt 2 and an adjustment structure 3 are fixedly installed on the end face of the base plate 1 and on the front and rear sides.

[0026] The adjustment structure 3 includes two fixed plates 31 symmetrically mounted on the end face of the base plate 1. The corresponding surfaces of the two fixed plates 31 are symmetrically rotated and mounted with a first roller 32. The left fixed plate 31 is rotatably connected to a lead screw 33 through a bearing. The lead screw 33 is threadedly connected to a threaded sleeve 34. The upper end of the threaded sleeve 34 extends to the outside of the fixed plate 31 and is mounted with a motor 35. A second roller 36 is rotatably mounted on the threaded sleeve 34.

[0027] In use, the roll material passes sequentially above the rear first roller 32, below the second roller 36, and above the front first roller 32 before falling onto the conveyor belt 2. The motor 35 drives the lead screw 33 to rotate in either the forward or reverse direction. The lead screw 33 moves the threaded sleeve 34 up or down, which in turn moves the support shaft 361. The support shaft 361 then moves the second roller 36 up or down. When the second roller 36 moves upward and closer to the two first rollers 32, the tension of the roll material decreases. When the second roller 36 moves downward and away from the two first rollers 32, the tension of the roll material increases. This achieves tension adjustment of the roll material, avoiding the problem that existing feeding traction devices do not have the function of adjusting the tension of the roll material. Excessive tension can lead to damage to the roll material and poor stability during the cutting process. This increases the stability of the roll material during cutting and improves the production efficiency of the roll material.

[0028] In this embodiment, a fixed shaft 321 is rotatably connected to the inner wall of the first roller 32. The two ends of the fixed shaft 321 are connected to two fixed plates 31. The motor 35 is fixedly connected to the end face of the fixed plate 31. A sliding groove 311 is provided on the fixed plate 31. A vertical rod 37 is installed on the right fixed plate 31 through the sliding groove 311. A sliding sleeve 371 is slidably connected to the vertical rod 37. A support shaft 361 is rotatably connected to the inner wall of the second roller 36. The corresponding surfaces of the threaded sleeve 34 and the sliding sleeve 371 are connected to the two ends of the support shaft 361.

[0029] Among them, a vertical rod 37 is installed through a sliding groove 311 via a right-side fixed plate 31. The vertical rod 37 is slidably connected to a sliding sleeve 371, which works with a threaded sleeve 34 to lift the second roller 36, thereby improving the lifting stability of the second roller 36.

[0030] In this embodiment, vertical plates 4 are symmetrically installed on the conveyor belt 2 on both the front and rear sides, and mounting shafts 41 are installed on the corresponding surfaces of the two vertical plates 4. A third roller 5 is rotatably installed on the outer wall of the mounting shafts 41.

[0031] When the conveyor belt 2 carries the roll material through the third roller 5, the roll material may not adhere to the surface of the conveyor belt 2 and may be deformed. When the roll material passes under the third roller 5, it is flattened by the third roller 5 and adhered to the conveyor belt 2, which brings convenience to the next processing step of the roll material.

[0032] Example 2

[0033] Unlike Embodiment 1, in the prior art, when the roll material arrives at the cutting process through the conveying mechanism, multiple roll material heads will come into contact together. Before entering the cutting device, manual tools are required to separate the roll material heads, which increases labor costs and is not conducive to the cutting device cutting the roll material. Therefore, a separation structure 6 is installed on the conveyor belt 2.

[0034] The separation structure 6 includes a support plate 61 fixedly installed on the front side of the conveyor belt 2. A first guide plate 62 and a second guide plate 63 are symmetrically installed on the end face of the support plate 61. The ends of the first guide plate 62 and the second guide plate 63 near the conveyor belt 2 are inclined portions 65.

[0035] In use, multiple rolls of material, after being flattened by two sets of third rollers 5, adhere tightly to the surface of the conveyor belt 2. The heads of the multiple rolls of material enter the channels between the corresponding first guide plates 62 and second guide plates 63. The multiple sets of first guide plates 62 and second guide plates 63 fix the distance between the multiple rolls of material, avoiding the problem in the prior art where the heads of multiple rolls of material come into contact with each other when the rolls of material pass through the conveyor mechanism to the cutting process, and requiring manual separation of the rolls of material heads with hand tools before entering the cutting device. This reduces labor costs and is also beneficial for the cutting device to cut the rolls of material, improving the cutting efficiency of the rolls of material.

[0036] In this embodiment, connecting plates 611 are symmetrically installed on the bottom of the support plate 61. The sidewalls of the two connecting plates 611 are connected to the front and rear of the conveyor belt 2. Multiple sets of first guide plates 62 and second guide plates 63 are provided. A through groove 64 is opened on the front of the support plate 61. A displacement structure 7 is installed on the front of the first guide plate 62 and the second guide plate 63. The displacement structure 7 includes an extension 712 fixedly installed on the first guide plate 62 and the second guide plate 63. A T-shaped block 71 that is slidably connected to the through groove 64 is installed at the bottom of the extension 712. The T-shaped block 71 is connected to a bolt 72 through a threaded hole 711.

[0037] The T-block 71 and bolt 72 are used together to adjust the position of the first guide plate 62 and the second guide plate 63, change the distance between the first guide plate 62 and the second guide plate 63, and then fix the T-block 71 in the through groove 64 by using the knob bolt 72 to realize the conveying and processing of rolls of different widths.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
