Description

Technical Field

[0001] This utility model relates to the field of screen plate processing technology, specifically a polyurethane-edged screen plate that facilitates the replacement of screen bars. Background Technology

[0002] Screen plates, also known as perforated plates, offer excellent wear resistance, long service life, and good moisture and abrasion resistance. They are suitable for use in machinery industries such as ore washing, screening, grading, slag removal, desliming, and dewatering. Polyurethane-edged screen plates boast superior wear resistance and a long service life—more than ten times that of metal screens, 3-5 times that of ordinary rubber sheets, and 2-3 times that of stainless steel. The elasticity of polyurethane allows the edged screen plates to withstand vibration and impact while maintaining stable screening performance and extending service life. During the screening process, when material falls onto the screen plate, it exerts a significant impact force on the stainless steel screen bars. Over time, the stainless steel screen bars may deform or bend, requiring replacement to maintain screening efficiency.

[0003] Because the existing polyurethane-edged screen panels are a single unit, the internal stainless steel screen bars cannot be replaced individually. Therefore, after prolonged bending, the entire polyurethane-edged screen panel must be replaced, which increases the cost of use and wastes resources. Utility Model Content

[0004] The purpose of this utility model is to provide a polyurethane-edged screen plate that facilitates the replacement of screen bars, in order to solve the problem mentioned in the background art that the existing polyurethane-edged screen plate is a one-piece structure, and the stainless steel screen bars installed inside cannot be replaced individually. Therefore, after long-term bending, the entire polyurethane-edged screen plate can only be replaced, which increases the cost of use and wastes resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane-edged screen plate that facilitates the replacement of screen bars, comprising a screen plate outer frame, a polyurethane protective edge, a curved groove, an installation device, and a fixing device. The polyurethane protective edge is installed on the outer side of the screen plate outer frame, a curved groove is provided in the center of the rear plate of the screen plate outer frame, an installation device is provided on the inner side of the screen plate outer frame, and a fixing device is installed inside the installation device.

[0006] Preferably, the installation device includes a rotating shaft, a rotating rod, a side groove, a mounting frame, a push plate, and a plug-in groove. The rotating shaft is installed on one side of the front end of the screen plate outer frame, the rotating rod is installed on the other side of the rotating shaft, the two ends of the screen plate outer frame are provided with side grooves, the mounting frame is installed inside the side grooves, the rear end of the mounting frame is connected to the push plate, and the inner side of the mounting frame is provided with a plug-in groove.

[0007] Preferably, the outer frame of the sieve plate forms a rotating structure through a rotating shaft and a rotating rod, and the installation position of the push plate is exactly inside the curved groove.

[0008] Preferably, the rear ends of the two sets of mounting brackets are connected by push plates, and each set of mounting brackets has six sets of insertion slots.

[0009] Preferably, the fixing device includes a plug plate, a mounting groove, a pressure rod, a movable frame, and a slider. The plug plate is installed inside the mounting device, the mounting groove is opened inside the plug plate, the pressure rod is connected to the inner side of the mounting groove, the movable frame is opened on both sides of the plug plate, and the slider is provided on the outer side of the movable frame.

[0010] Preferably, the insertion slot and the insertion plate are connected by an insertion joint, and the pressure rod forms a locking structure with the slider through a movable frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The installation device forms a rotating and pushing structure for easy removal and installation of screen bars. The rotating shaft and rotating rod form a rotating mechanism, which allows the rotating rod to remove the mounting bracket from the side groove when the screen bars need to be replaced. The rear ends of these mounting brackets are connected by push plates to maintain overall stability.

[0013] The plug plate to be replaced is removed by fixing device. The slider is slid upward by moving frame, and the pressure rod is lifted upward to remove the screen bar to be replaced from the mounting slot. The screen bar is fixed and adjusted by moving frame and slider to ensure the stability and reliability of screen bar during replacement. This makes screen bar replacement simple and quick, while reducing the cost and resource waste caused by replacing the whole screen plate. Attached Figure Description
