Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belt processing equipment, in particular to an abrasive belt slitter. Background Art

[0002] A slitter is a device for longitudinally cutting wide coiled materials. According to its scope of use, it can be divided into the following categories: for slitting paper, which is also the mainstream product in current packaging equipment and is often seen in the packaging market; for slitting industries that require leather, cloth, plastic, film, etc.; for slitting metal coils, such as slitting strip steel, stainless steel, copper, etc., for steel processing plants, steel market operators, rolling mills, electrical industries, automobiles, stamping parts, etc. Among them, the endless abrasive belt belongs to one type of abrasive belt, and the produced and formed endless abrasive belt usually has a relatively wide width. In order to facilitate the use of the endless abrasive belt for grinding, an abrasive belt slitter is usually used to slit the abrasive belt.

[0003] According to the patent publication number (CN214445645U), an abrasive belt slitter is disclosed, which includes a frame and a cutter roller. The frame is vertically arranged, and the bottom end of the frame is fixedly connected to the ground. One end of the cutter roller is rotatably connected to the frame. The abrasive belt slitter includes a rotating roller, an adjusting roller, a first drive for driving the cutter roller to rotate and move, and a second drive for driving the rotating roller to rotate.

[0029] In this embodiment, the slitter can accurately cut the material according to preset parameters, divide it into strip-shaped materials with specified widths, and finally the mechanism is responsible for collecting the cut strip-shaped materials for subsequent processing. When processing the annular sanding belt 8, first control the adjusting roller 4 to approach the rotating roller 3 to reduce the distance between the adjusting roller 4 and the rotating roller 3, which is convenient for sleeving the annular sanding belt 8 on the adjusting roller 4 and the rotating roller 3. Then control the adjusting roller 4 to move away from the rotating roller 3 to increase the distance between the adjusting roller 4 and the rotating roller 3, so as to tension the annular sanding belt 8, which is convenient for subsequent cutting of the annular sanding belt 8 (please refer to Figure 1 ). A first limiting roller 5 is installed between the rotating roller 3 and the adjusting roller 4, and the rotating roller 3, the first limiting roller 5 and the adjusting roller 4 are at the same horizontal height. After the annular sanding belt 8 is sleeved on the adjusting roller 4 and the rotating roller 3, the first limiting roller 5 is located inside the annular sanding belt 8, and the annular sanding belt 8 just fits into the anti-deviation area 10 (the width of the annular sanding belt 8 is adapted to the distance between the two first limiting members 6), so as to avoid the problem of deviation of the annular sanding belt 8 during processing, and the annular sanding belt 8 can be divided into more accurate strip-shaped materials. During processing, the rotating roller 3 starts to rotate, and the annular sanding belt 8 is transmitted between the rotating roller 3 and the adjusting roller 4, and then the knife roller 2 moves towards the rotating roller 3 until the annular sanding belt 8 can be cut, and the annular sanding belt 8 can be cut into accurate strip-shaped materials during transmission. The annular sanding belt 8 is stuck in the anti-deviation area 10 during processing, avoiding the problem of deviation of the annular sanding belt 8; at the same time, the size of the anti-deviation area 10 is adjustable and applicable to sanding belts of different sizes. Therefore, when installing the annular sanding belt 8, there is a large operating space, and there is no need to prevent the annular sanding belt 8 from deviating and increase the tension force borne by the annular sanding belt 8, resulting in the problem of tearing of the annular sanding belt 8; at the same time, there is no need to prevent the annular sanding belt 8 from tearing and reduce the tension force borne by the annular sanding belt 8, resulting in the problem of deviation of the annular sanding belt 8.

[0030] Further, in the present utility model, the first limiting member 6 is sleeved on the first limiting roller 5, and the first limiting member 6 and the first limiting roller 5 are in threaded cooperation.

[0031] In this embodiment, the first limiting member 6 can be disc-shaped, and the first limiting members 6 are installed on both sides of the first limiting roller 5. An anti-deviation area 10 is formed between the two first limiting members 6. During processing, the annular abrasive belt 8 is clamped between the two first limiting members 6, and both sides of the annular abrasive belt 8 are in contact with the first limiting members 6, thereby preventing the annular abrasive belt 8 from deviating. The first limiting member 6 can rotate relative to the first limiting roller 5 to adjust the distance between the two first limiting members 6, thereby adjusting the size of the anti-deviation area 10 to be suitable for annular abrasive belts 8 of different sizes.

When installing the annular abrasive belt 8, the upper layer of the annular abrasive belt 8 is inserted between the second limiting roller 7 and the third limiting roller 9 (anti-curl area 18). The thickness of the annular abrasive belt 8 is adapted to the size of the anti-curl area 18, and the annular abrasive belt 8 can prevent the annular abrasive belt 8 from curling due to curvature deformation during transmission.

[0034] Further, in the present utility model, the frame 1 is provided with two oppositely arranged third limiting rollers 9, and the two third limiting rollers 9 are respectively located on both sides of the second limiting roller 7.

[0035] In this embodiment, both of the two third limiting rollers 9 form an anti-curl area 18 with the second limiting roller 7. When installing the annular abrasive belt 8, the upper layer of the annular abrasive belt 8 is clamped into one of the anti-curl areas 18, and the lower layer of the annular abrasive belt 8 is clamped into the other anti-curl area 18, which can prevent the upper layer and the lower layer of the annular abrasive belt 8 from curling at the same time.

[0036] Further, in the present utility model, a second limiting component is further included; an installation groove 11 is provided on one side of the third limiting roller 9 facing the second limiting roller 7, and the second limiting component is installed in the installation groove 11, and the second limiting component can press against the second limiting roller 7.

The outer side wall of the limiting housing 13 is in sliding fit with the surface wall of the installation groove 11, so that the limiting housing 13 can reciprocate axially along the installation groove 11, and an elastic member is connected between the limiting housing 13 and the installation groove 11, so that the pressing member 14 can always press towards the second limiting roller 7. When installing the annular abrasive belt 8, the limiting housing 13 is pressed into the installation groove 11. After installation, the pressing member 14 presses towards the annular abrasive belt 8 under the action of the elastic member. When the annular abrasive belt 8 is transmitted, the pressing member 14 rotates at the same frequency, thereby preventing the problem of curling of the annular abrasive belt 8. At the same time, the distance between the pressing member 14 and the second limiting roller 7 is adjustable, suitable for annular abrasive belts 8 of different sizes.

[0040] Further, in the present utility model, the elastic member includes a return spring 12; one end of the return spring 12 is connected to the surface wall of the installation groove 11, and the other end of the return spring 12 is connected to the outer side wall of the limiting housing 13.
