Description

Technical Field

[0001] The utility model belongs to the technical field of sieve plates, and in particular relates to a polyurethane-edged metal sieve plate that is easy to use. Background Art

[0002] The polyurethane-edged sieve plate includes a polyurethane edging, a metal frame and stainless steel screen bars, and the stainless steel screen bars are fixed to the inner wall of the metal frame, and the polyurethane edging is arranged on the outer wall of the metal frame. During the screening process, when the material falls onto the sieve plate, the polyurethane-edged sieve plate will produce a large impact force on the stainless steel screen bars. As the use time increases, the stainless steel screen bars will be deformed and bent. In order not to affect the screening effect, it is often necessary to replace new stainless steel screen bars.

[0003] However, most of the existing polyurethane-edged screen plates are usually one-piece structures, that is, the stainless steel screen bars cannot be replaced individually, so the polyurethane-edged screen plate can only be replaced as a whole. This not only increases the cost of use, but also brings inconvenience to the use of the polyurethane-edged screen plate. For this reason, we propose a convenient-to-use polyurethane-edged metal screen plate. Utility Model Content

[0004] The purpose of the utility model is to provide a polyurethane-wrapped metal sieve plate that is easy to use, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a convenient-to-use polyurethane-edged metal sieve plate, comprising a metal frame and sieve bars, wherein the outer fixed sleeve of the metal frame is provided with a polyurethane edging, an insert hole is provided inside the bottom end of the metal frame, a movable block is movably sleeved inside the insert hole, and the bottom of the movable block is transmission-connected to the inner wall of the metal frame via a movable spring;

[0006] A card slot is provided on the front of the top of the metal frame, and a limiting block is fixedly connected inside the card slot. A pressing plate is provided on the front of the top of the metal frame, and a mounting block is fixedly connected to the side of the pressing plate.

[0007] As a preferred embodiment, the screen bar is in the shape of a cylinder, and the bottom end of the screen bar is movably sleeved inside the socket.

[0008] As a preferred embodiment, the top of the moving block contacts the bottom end of the screen bar, the movable spring is located inside the socket, and the two ends of the movable spring are fixedly connected to the inner wall of the metal frame and the bottom of the moving block respectively.

[0009] As a preferred embodiment, the top end of the screen bar is located inside the slot, and the slot and the insertion hole correspond to each other.

[0010] As a preferred embodiment, the material of the limiting block is rubber material, and the limiting block is in close contact with the screen bars.

[0011] As a preferred embodiment, the back side of the pressing plate is in close contact with the front side of the top end of the screen bar, and the mounting block and the metal frame are fixedly connected by bolts.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The easy-to-use polyurethane-edged metal sieve plate is provided with jacks, movable blocks, movable springs, slots, limit blocks, pressure plates, mounting blocks and bolts. When the sieve bars are damaged during the use of the polyurethane-edged metal sieve plate, the sieve bars can be easily disassembled and replaced, avoiding the traditional problem of increasing the use cost by replacing the entire sieve plate. The method of disassembling and assembling the sieve bars is simple to operate, thereby bringing convenience to the use of the polyurethane-edged metal sieve plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0021] See also Figure 1 、 Figure 2 and Figure 3The utility model provides a convenient-to-use polyurethane-edged metal sieve plate, comprising a metal frame 1, screen bars 3 and insertion holes 4. The external fixed sleeve of the metal frame 1 is provided with a polyurethane edging 2. A card slot 7 is provided on the front of the top of the metal frame 1. The top of the screen bar 3 is located inside the card slot 7. The card slot 7 and the insertion hole 4 correspond to each other. The inside of the card slot 7 is fixedly connected to a limiting block 8. The limiting block 8 is made of rubber material. The limiting block 8 and the screen bar 3 are in close contact. A pressing plate 9 is provided on the front of the top of the metal frame 1. The side of the pressing plate 9 is fixedly connected with a mounting block 10. The back of the pressing plate 9 is in close contact with the front of the top of the screen bar 3. The mounting block 10 and the metal frame 1 are fixedly connected by bolts 11.

[0022] In this embodiment, when the damaged screen bar 3 needs to be disassembled and replaced, the bolt 11 is first rotated to separate it from the metal frame 1. At this time, the pressure plate 9 and the metal frame 1 will become loose, and the pressure plate 9 is removed from the front of the metal frame 1. At this time, the top of the screen bar 3 will be exposed, and then the top of the screen bar 3 is depressing, so that the top of the screen bar 3 and the limit block 8 are separated, thereby causing the top of the screen bar 3 to slightly tilt up.

[0023] See also Figure 1 、 Figure 2 and Figure 4 , a socket 4 is opened inside the bottom end of the metal frame 1, the screen bar 3 is in the shape of a cylinder, the bottom end of the screen bar 3 is movably sleeved inside the socket 4, and a moving block 5 is movably sleeved inside the socket 4. The bottom of the moving block 5 is transmission-connected to the inner wall of the metal frame 1 through a movable spring 6, the top of the moving block 5 is in contact with the bottom end of the screen bar 3, the movable spring 6 is located inside the socket 4, and the two ends of the movable spring 6 are fixedly connected to the inner wall of the metal frame 1 and the bottom of the moving block 5 respectively;

[0024] In this embodiment, when the top end of the screen bar 3 is slightly tilted, force is applied to the top end of the screen bar 3 so that the bottom end of the screen bar 3 pushes the movable block 5, and the movable spring 6 is compressed and deformed. At this time, the top end of the screen bar 3 is taken out from the inside of the slot 7, and then the screen bar 3 is pulled outward so that the bottom end of the screen bar 3 is moved out from the inside of the socket 4, thereby facilitating the disassembly and replacement of the screen bar 3.

[0025] The working principle and use process of the utility model are as follows: first, the bolt 11 is rotated to separate it from the metal frame 1. At this time, the pressure plate 9 and the metal frame 1 will become loose, and the pressure plate 9 is removed from the front of the metal frame 1. At this time, the top of the screen bar 3 will be exposed;

[0026] Then, the top of the screen bar 3 is pulled to separate the top of the screen bar 3 from the limiting block 8, thereby causing the top of the screen bar 3 to slightly tilt up. Then, force is applied to the top of the screen bar 3, so that the bottom end of the screen bar 3 pushes the moving block 5, and the movable spring 6 is compressed and deformed.

[0027] Finally, the top end of the screen bar 3 is taken out from the inside of the slot 7, and the screen bar 3 is pulled outward so that the bottom end of the screen bar 3 is removed from the inside of the insertion hole 4, thereby facilitating the disassembly and replacement of the screen bar 3.
