Description

Technical Field

[0001] This utility model relates to the technical field of screen drum processing equipment, and in particular to a screen drum fixing ring rolling device. Background Technology

[0002] Screen drums are widely used in the papermaking and wastewater treatment industries. They are used in the papermaking industry to separate impurities in pulp to improve pulp quality, or in the wastewater treatment industry to separate solids in wastewater to improve wastewater cleanliness. Their structure mainly consists of upper and lower flanges, wedges, and a fixed drum ring.

[0003] In the traditional screen drum industry, the processing of fixed drum rings is usually done by cutting circular structures from metal sheets. This processing method produces a large amount of material after cutting the metal sheets, and because the metal sheets are large and heavy, the cutting method is also cumbersome, resulting in high processing costs and low processing efficiency. Now, metal bars are used as the raw material for fixed drum rings. By bending the metal bars into circular shapes, the manufacturing cost can be greatly reduced and the processing efficiency can be improved.

[0004] Because the diameter of the fixing ring in the screen drum is large and the wall thickness of the fixing ring is thin, it is usually processed one by one. However, existing rolling machines, such as the Chinese Patent Publication No. CN218775459U which discloses a rolling machine for steel pipe processing, belong to the field of rolling machine technology. This rolling machine for steel pipe processing includes a support structure and a rolling mechanism. The support structure includes a support frame and a top plate, with the top plate fixed to the top surface of the support frame. The rolling mechanism includes a first fixing block, two sliding parts, a first servo motor, and a second fixing block. The first fixing block has a cavity inside, and a second threaded rod is fixed to the other end of the first threaded rod. The first servo motor is mounted on the sliding parts, and a support roller is installed at the end of the output shaft of the first servo motor. The second fixing block is fixed to the other side of the top surface of the top plate. A driving component is installed in the limiting groove, and an extrusion component is installed on the driving component.

[0005] This rolling machine is not suitable for processing thin-walled fixed rings. During the rolling process, due to the long length of the steel, the steel may sag or deform due to lack of support, and it may also swing left and right during the rolling process, affecting its processing accuracy and even affecting the closure of the ring. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a screen drum fixing ring rolling device to solve the problem that the workpiece is prone to shaking during the rolling process, which affects the processing accuracy.

[0007] To achieve the above and other related objectives, this utility model provides a screen drum fixing ring rolling device, including a frame, a rolling mechanism disposed on the frame, and a plurality of guide rollers disposed vertically next to the rolling mechanism and capable of contacting the side wall of the workpiece. The frame is provided with a support frame for mounting the guide rollers, and the support frame is provided with a first adjustment component capable of adjusting the horizontal distance between each guide roller and the workpiece, and a second adjustment component disposed on the frame capable of adjusting the height of the frame.

The rotating shaft is arranged along the axis of the guide roller, and each guide roller is arranged parallel to the workpiece feeding direction.

[0010] By adopting the above technical solution, multiple guide rollers are installed in the connecting seat, which increases the contact area between the guide rollers and the workpiece and improves the limiting effect. Moreover, installing the guide rollers in one connecting seat makes it easier to adjust the position of the guide rollers.

[0011] In one embodiment of the present invention, the first adjustment component includes a connecting rod fixedly mounted on the connecting seat and slidably connected to the support frame, a sliding groove mounted on the support frame, and an adjustment screw rotatably connected to the support frame about the extension direction of the sliding groove and threadedly engaged with the connecting rod.

[0012] By adopting the above technical solution, the distance between the guide roller and the workpiece can be adjusted by rotating the adjusting screw to drive the connecting rod to move axially.

[0013] In one embodiment of the present invention, the second adjustment component includes a support rod vertically disposed on the frame, a sliding seat fixedly disposed at the end of the support frame and slidably connected to the support rod vertically, a plurality of adjustment holes evenly arranged along the axis of the support rod, and a quick-release pin disposed on the sliding seat that can be inserted into the adjustment hole.

[0014] By adopting the above technical solution, the sliding seat can be inserted into the adjustment hole via a quick-connect pin, thereby adjusting the height of the connecting seat on the support frame. The adjustment method is simple and convenient.

[0015] In one embodiment of the present invention, the support rod is rotatably connected to the frame about its axis. The frame is also provided with a limiting component that can lock the support rod after the support frame is flipped to the side of the workpiece. The limiting component includes a horizontal bar fixedly disposed on the side wall of the support rod in the horizontal direction, a locking plate that is disposed corresponding to the position of the horizontal bar and can embed the horizontal bar, and an elastic buckle disposed on the locking plate.

[0016] By adopting the above technical solution, the support frame can be rotated to one side of the machine frame by rotating the support rod when the machine is stopped, and the support frame can be folded up, making its overall structure more compact and space utilization more reasonable.

[0017] In one embodiment of the present invention, the rolling mechanism includes two drive rollers arranged parallel to each other on the lower side of the frame, an auxiliary roller arranged between the two drive rollers and located on the upper side thereon, a processing wheel installed at the ends of the drive rollers and the auxiliary rollers for clamping the workpiece, and a drive component that serves as a power source to drive the drive rollers to rotate.

[0018] By adopting the above technical solution, the rolling process of the workpiece can be realized.

[0019] In one embodiment of the present invention, the frame is further provided with a lifting assembly capable of driving the auxiliary roll to move in the vertical direction. The lifting assembly includes a bearing seat rotatably connected to the auxiliary roll on the frame, a lifting screw rotatably connected to the bearing seat in the vertical direction and threadedly engaged with the frame, and a handle provided at the upper end of the lifting screw.

[0020] By adopting the above technical solution, the height of the auxiliary rolls can be adjusted.

[0021] In one embodiment of the present invention, each guide roller surface is provided with a flexible pad.

[0022] By adopting the above technical solution, the guide roller can make flexible contact with the workpiece, improve the friction coefficient, and make it easier to contact and limit the workpiece.

[0023] As described above, the screen drum fixing ring rolling device of this utility model has the following beneficial effects: when processing a workpiece, the guide wheel on the support frame can abut against the side wall of the workpiece, and through the frictional force, it can provide auxiliary support and limit the workpiece, making it less likely to shake during processing and ensuring the processing accuracy of the workpiece. Moreover, the distance and height between the guide roller and the workpiece can be adjusted by the first adjustment component and the second adjustment component, so that it can be adapted to workpieces of different sizes and models, further improving its applicability.
