Description

[Detailed Description of the Invention] The present invention relates to a side edge locking mechanism of an elastic sieve net.

In vibrating sieving operations, elastic sieving screens have become widely popular in recent years because they produce less noise than wire mesh and the like, and have excellent corrosion resistance and abrasion resistance. If this elastic sieve net is to be formed in one piece to a size (screen size) to be attached to a single sieving machine, the manufacturing process will be complicated and there will be major economical and other problems. Therefore, a method is often used in which a large number of unit plates of elastic bodies having a desired mesh size are manufactured, and these are arranged and connected vertically and horizontally to obtain a single sieve screen. With this method, the mold for molding is small and economical, and the time required for molding can be shortened. However, there are various types of unit plates and connection structures, and recently, rectangular (preferably square) unit plates with a desired mesh and grooves along the mesh are provided vertically and horizontally. The main method of connecting and integrating a large number of wires is by welding the edges that preferably contact each other and embedding tensile wires in the vertical and horizontal grooves aligned with each other.

The present invention attempts to form strong hook edges for attaching both side edges of the sieve net to the vibration mechanism of a machine by using both ends of such a tensile wire rope for connection reinforcement. Conventionally, this type of hook edge in an elastic sieve net has been constructed by constructing the net structure from resin-coated wire rope itself rather than from molded unit plates, as shown in, for example, Japanese Utility Model Publication No. 56-37823. There are structures that were developed to engage the edge of the sieve mesh, and they can be broadly divided into those that simply have the tip of a resin-coated wire rope sandwiched between a hook plate and a backing plate;
The tip of a resin-coated wire rope is clamped and supported by a double-folded hook plate, and the hook plate is applied to the tip of a wire rope with the resin coating removed, and the hook plate is integrally hardened with resin.

However, these conventional hook edges are
In the method (2), the wire rope easily separates or breaks from the hook fitting, and in the method (2), the hardened resin is broken and the wire rope is likely to come off.

The purpose of the present invention is to securely and firmly connect wire ropes protruding from both sides of an elastic sieve net made up of a large number of unit plates, thereby preventing wire rope separation and cutting as described above. An object of the present invention is to provide an engaging hook edge that minimizes problems such as the above.

Briefly, the hook edge of the present invention is a wire rope buried in parallel on the back side of an elastic sieve net made up of a large number of unit plates, and a tube-shaped metal is attached to the tips protruding from both side edges of the sieve net. The locking mechanism is constructed by putting the unit plate on and crimping it and bending it into a hook shape on the front or back side of the unit plate.

In the example, even if the arrangement of unit plates is reinforced with a resin-coated wire rope, the resin coating is peeled off at the tip and the tubular metal is crimped onto the wire rope itself, so the connection between the two is extremely difficult. Becomes strong. In addition, when bending tube-shaped metal into a hook shape, there is a method in which bent edge plates are placed over and fixed to the array of these metal elements protruding from the side edge of the sieve screen, and in this state they are collectively shaped into a hook shape. is taken.

Hereinafter, preferred embodiments will be described with reference to the drawings.

FIG. 1 shows a screen unit plate 1 reinforced with wire ropes 6. As shown in FIG. In the embodiment, the unit plate 1 is made of polyurethane and has a large number of meshes 3, as well as a plurality of reinforcing bodies 4 having a width wider than the normal width between the meshes set in the horizontal direction in FIG.
Grooves 5 as shown in FIG. 2 are selectively formed on the back surface. The resin-coated wire rope 6 is inserted into the grooves 5 and fixed in a state in which the necessary number of unit plates 1 are arranged vertically and horizontally with the grooves 5 aligned in one direction. This is done by using the same polyurethane resin as the unit plate 1 for the coating resin 8 covering the core wire 7 made of stainless steel, for example, of the wire rope 6, and softening both the inner wall of the groove 5 and the coating resin 8 of the rope with hot air. , by melting and contacting.

In FIG. 3, the unit plates 1 are cut into appropriate dimensions at the periphery, so that the unit plates 1 are sequentially shifted in a roughly staggered or zigzag pattern in the direction of the processing flow path (vertical direction in the figure). The sieve net 9 is shown completely aligned in the flow path transverse direction.

According to the present invention, hook edges 10 as shown in FIGS. 3 and 4 are formed in portions of the sieve net 9 corresponding to both side edges of the processing channel. This hook edge 10 is supported by a vibration support mechanism (not shown) of a vibrating sieve machine on its back surface which is connected to the back surface of the unit plate, and its upward hook-shaped concave surface is locked from the outside. . This results in
The sieve net 9 can withstand strong tensile loads due to its own weight and the weight of the processed material. That is, this tensile load is sufficiently supported by the covered wire rope 6 whose both ends are fixed to these hook edges 10.

FIG. 5 is a cross-sectional view of the hook edge, and each hook portion is formed by removing the covering of the wire rope 6 protruding from the edge of the unit plate 1 located at the side end of the sieve channel, and attaching the exposed core wire 7 to the exposed core wire 7, for example. A hook element 13 is placed on a stainless steel tube and crimped and crimped so as to have a triangular cross section (FIG. 6). The hook edge 10 includes the entire row of hook elements 13 that successively protrude along the side edge of the sieve screen 9.
For example, a bent hook cover plate 14 made of stainless steel is sandwiched from above and below, the edge (opening) of the plate 14 is placed over the edge of the corresponding unit plate 1, fixed with rivets 15, and then hook-shaped as shown in FIG. It is curved so that it has a cross section.

As described above, in the hook edge of the present invention, the wire rope as a reinforcing bar of the elastic sieve net is crimped to the hook element 13 at both ends and is integrated.
These rows of hook elements 13 along the side edge of the sieve screen are inserted as cores of the hook cover plate 14 made of a metal plate fixed to the side edge unit plate, so that the side edge of the sieve screen can be locked very firmly. It provides a mechanism.
