[0001] The present application relates to the technical field of cold rolling processing, and in particular to an adjustable rolling mill. Background Art
[0002] A rolling mill is a device that adjusts the size and shape of a blank by pressure. A rolling mill usually includes one or more pairs of rollers. The blank is pressed between the rollers to achieve a uniform thickness. Rolling by a rolling mill can obtain a good size, shape and surface finish, and improve the mechanical properties of the blank.
[0003] For example, in the prior art, there is an adjustable cold rolling mill with anti-deviation, which is disclosed in the announcement number CN218798200U. By setting a guide plate, a T-shaped slider and a connecting mechanism, the cold rolling mill can provide anti-deviation protection for aluminum plates of more widths, thereby making the aluminum foil produced by the cold rolling mill convenient for winding by a winding mechanism and subsequent processing by staff.
[0004] However, when the device is in use, since the edge of the rolled stock is not straight, it is not accurate to limit the stock only from the side by the guide plate, and the stock still has a large space for movement in the vertical direction, and the anti-deviation effect is poor;
[0005] Therefore, the present application provides an adjustable rolling mill to meet the needs. Utility Model Content
[0006] In view of this, the purpose of the present application is to provide an adjustable rolling mill, which can cut the uneven edges of the billet with a blade to keep it flat, and then limit the billet in the vertical and horizontal directions to achieve a good anti-deviation effect.
[0007] In order to solve the above technical problems, this application provides the following technical solutions:

[0010] Preferably, a baffle is connected between the two dust covers, and the baffle is attached to the end of the roller.
[0011] Preferably, the height of the slider is consistent with the opening height of the dust cover, and the slider is arranged at the opening portion of the dust cover.
[0012] Preferably, the distance between the two groups of rollers on the side of the slider is the same as the distance between the two rollers.
[0013] Preferably, the blade is clamped between two connecting shafts, and the angle between the blade and the axis of the roller is 90 degrees.
[0014] Preferably, the inner side wall of the chassis is fixedly connected to a slide rail, the interior of the slide rail is slidably connected to a motor seat, the motor seat is fixedly connected to a motor, the end of the slide rail is fixedly connected to a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is fixedly connected to the motor seat.
[0015] Compared with the prior art, this application has at least the following beneficial effects:
[0016] In the above scheme, a dust cover, rollers and wheels are arranged, and the conveying direction of the blank is limited by the rollers at the end of the dust cover. The connecting line between the two sets of rollers passes through the roller gap, which has a preliminary anti-deviation effect. The blank is supported by the rollers, and the rollers limit the horizontal and vertical movement directions of the blank so that it can only slide along the feed direction, thereby having an anti-deviation effect.
[0017] In the above scheme, by setting a blade, a roller and a connecting shaft, blade edges are set on both side walls of the blade, which can cut the blank before entering the roller gap to make its edge smooth. At the same time, the vertical wall of the blade has a limiting effect on the blank to prevent it from horizontal deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 , Figure 2 , Figure 3 An adjustable rolling mill is shown, and the embodiment of the present application provides, comprising a machine box 1 and two rollers 2 arranged on one side thereof, a motor 101 is fixedly connected inside the machine box 1, and the output end of the motor 101 is drivingly connected to the roller 2, a dust cover 3 is provided on the front side of the machine box 1 along the feeding direction of the roller 2, a bidirectional screw rod 301 is penetrated through the side wall of the dust cover 3, a slider 302 is sleeved on the outer side of the bidirectional screw rod 301, and two parallel connecting shafts 303 are provided on the side wall of the slider 302, two rollers 304 are sleeved on both ends of the connecting shaft 303, a blade 305 is provided in the middle of the connecting shaft 303, two rollers 4 arranged in parallel up and down are provided at the end of the dust cover 3, a motor 2 5 is fixedly connected to the outside of the dust cover 3, and the motor 2 5 is drivingly connected to one of the rollers 4;
[0026] Dust covers 3 are provided on both sides of the rollers 2 to isolate the blank from contact with external dust. The blank is transported between the two rollers 2 inside the dust cover 3. The conveying direction of the blank is limited by the roller 4 at the end of the dust cover 3. The connecting line between the two groups of rollers 4 passes through the roller gap of the rollers 2, which plays a preliminary anti-bias effect.
[0027] The blank is supported by the roller 304, which limits the horizontal movement direction of the blank so that it can only slide along the feeding direction, thereby preventing deviation.
[0028] At the same time, blades are provided on both sides of the blade 305, which can cut the blank before entering the gap between the rollers 2 to make its edge smooth. At the same time, the vertical wall of the blade 305 has a limiting effect on the blank to prevent it from horizontal deviation.
[0029] One side of the slider 302 is provided with two groups of upper and lower rollers 304 corresponding to one side edge of the blank. The rollers 304 are used to limit the vertical movement space of the blank. The blade 305 is set between the two groups of rollers 304. Therefore, when the blank is transported by the rollers 304 away from the side of the slider 302, the other group of rollers 304 can transport the cut waste to prevent the waste from affecting the processing of the blank.
[0030] In this embodiment, Figure 2-Figure 4As shown: there are two dust covers 3, which are respectively arranged on both sides of the roller 2, and the opening width of the dust cover 3 is the same as the length of the roller 2;
[0031] The dust cover 3 can well shield the blank, reduce the contamination of foreign matter on the blank, ensure the processing quality, and prevent the potential safety hazard of the blank escaping from the roller gap.
[0032] A baffle 6 is connected between the two dust covers 3, and the baffle 6 is attached to the end of the roller 2;
[0033] The baffle 6 shields the end of the roller 2 to prevent the roller gap from being exposed to the outside world, and plays a limiting role on the roller 2 to form a good protective effect.
[0034] The height of the slider 302 is consistent with the opening height of the dust cover 3, and the slider 302 is arranged at the opening of the dust cover 3;
[0035] The slider 302 slides in the inner cavity of the dust cover 2, and the distance between the two sliders 302 can be adjusted by rotating the bidirectional screw rod 301 to adapt to the width of the blank, so that the blade 305 can accurately cut the waste edge of the blank, thereby ensuring the straightness of the edge of the blank.
[0036] The distance between the two sets of rollers 304 on the side of the slider 302 is the same as the distance between the two rollers 2;
[0037] The rollers 304 can support the blank well, keep the blank level when it is discharged, and reduce the deformation of the blank. At the same time, the two groups of rollers 304 limit the edges of the blank from the upper and lower sides respectively to prevent the blank from jumping in the vertical direction. At the same time, the blade 305 is set on one side of the roller 304 to avoid tearing the blank.
[0038] The blade 305 is clamped between the two connecting shafts 303, and the angle between the blade 305 and the axis of the roller 2 is 90 degrees;
[0039] The blank is pressed by the roller 304, and the blade 305 can prevent the incision from spreading toward the center of the blank when cutting the blank, thereby obtaining a straight cut surface.
[0040] The inner side wall of the chassis 1 is fixedly connected with a slide rail 102, the inner part of the slide rail 102 is slidably connected with a motor seat 103, the motor seat 103 is fixedly connected to the motor 101, the end of the slide rail 102 is fixedly connected with a hydraulic cylinder 104, and the telescopic end of the hydraulic cylinder 104 is fixedly connected to the motor seat 103;
[0041] The position of the motor seat 103 is adjusted by the hydraulic cylinder 104 to adjust the width of the roller gap to meet different processing requirements. The movement of the motor seat 103 is guided by the slide rail 102 to make the adjustment process smooth.
