Description

Technical Field

[0001] This utility model relates to the field of fiber particle sorting technology, and in particular to an elastic rope-type fiber particle sorting screen. Background Technology

[0002] In the recycling technology of waste tires, while rubber fiber preparation can effectively transform waste materials into fiber-reinforced materials, rubber particle contamination is unavoidable during the mechanical grinding process. These rubber particles have significant morphological differences from the fibrous structure required for the target product and lack bridging properties. Therefore, it is essential to develop efficient sorting equipment to achieve precise separation of rubber particles and rubber fibers. Existing common sorting devices mostly use vertically vibrating screens, and their sorting mechanism is mainly based on the difference in material particle size. Although this traditional process is applicable to conventional particle systems, it reveals significant limitations when processing special materials such as tire rubber fibers. Rubber fibers are easily mixed with particles during vertical vibration, resulting in reduced sorting efficiency (i.e., fibers are mixed in with the screened particles). Therefore, it is necessary to design a dedicated, high-efficiency screening device based on the difference in the geometric aspect ratio of rubber fibers and particles. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model proposes a separator for separating rubber fibers and rubber particles that utilizes inertia and a pull rope to achieve reciprocating rotational motion. It has the advantages of simple and compact structure, good screening effect, and convenient operation.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an elastic pull-rope type fiber particle sorting screen, characterized in that it comprises: a base plate, a rope guide, an elastic pull rope, a stabilizing column, a rotating sleeve, a rope fixing screw, a feeding tray, a buckle, and a separating tray; the base plate is a rectangular structure used as a base; the rope guide is a pair of structures with round bars at the bottom and rings at the top, welded and fixedly installed on the base plate; the elastic pull rope is a pair of long ropes with good elasticity and toughness and pull rings at the ends; the stabilizing column is a cylinder and welded and fixedly installed on the base plate; the rotating sleeve is a cylindrical structure with a radial groove on its outer circumference to facilitate rope attachment. The inner wall of the rotating sleeve and the outer wall of the stabilizing column are installed with a clearance fit. There is a pair of rope fixing screws, which can fix the head ends of a pair of elastic pull ropes in the groove of the rotating sleeve. The feeding tray is fixed on the top of the rotating sleeve to receive the sorted rubber particles. There is a pair of buckles, which are installed on both sides of the feeding tray by shaft connection. The separating tray is a screen tray with a screen at the bottom and an annular barrier ring in the middle. The screen aperture is slightly larger than the diameter of conventional rubber particles and the radial dimension of rubber fibers, but smaller than the axial dimension of conventional rubber fibers. After the buckles are closed, they can fit into the notch of the separating tray to fix the separating tray on the top of the feeding tray.

[0005] Compared with the prior art, the advantages of this utility model are: by repeatedly pulling and releasing a pair of elastic ropes, the inertia is used to realize the periodic forward and reverse rotation of the sorting screen, so that the recycled rubber fibers and rubber particles of waste tires roll on the screen and are sorted by the screen due to their different length-to-diameter ratios. This avoids the fibers from accidentally passing through the screen along with the rubber particles during the up-and-down vibration. It has the advantages of simple and compact structure, easy use, and good sorting effect. Attached Figure Description

[0009] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit this utility model.

[0010] like Figure 1 As shown, an elastic draw rope type fiber particle sorting screen is characterized by comprising: a base plate 1, a rope guide 2, an elastic draw rope 3, a stabilizing column 4, a rotating sleeve 5, a rope fixing screw 6, a material tray 7, a buckle 8, and a separating tray 9; the base plate 1 is a rectangular structure used as a base; the rope guide 2 is a pair of structures with round bars at the bottom and rings at the top, and is fixedly installed on the base plate 1; the elastic draw rope 3 is a pair of long ropes with good elasticity and toughness and rings at the ends; the stabilizing column 4 is a cylinder and is fixedly installed on the base plate 1; the rotating sleeve 5 is a cylindrical structure with a radial groove on its outer circumference to facilitate rope attachment; the rotating sleeve 5 contains... The wall is installed with the outer wall of the stabilizing column 4 through a clearance fit. There is a pair of rope fixing screws 6, which can fix the head end of a pair of elastic pull ropes 3 in the groove of the rotating sleeve 5. The feeding tray 7 is fixed on the top of the rotating sleeve 5 to receive the sorted rubber particles. There is a pair of buckles 8, which are installed on both sides of the feeding tray 7 through shaft connection. The separating tray 9 is a screen tray with a screen at the bottom and an annular barrier ring in the middle. The screen aperture is slightly larger than the diameter of conventional rubber particles and the radial dimension of rubber fibers, but smaller than the axial dimension of conventional rubber fibers. After the buckles 8 are closed, they can fit into the notch of the separating tray 9 to fix the separating tray 9 on the top of the feeding tray 7.

[0011] like Figure 1As shown, the working principle and working steps of the elastic draw rope type fiber particle sorting screen of this utility model are as follows:

[0012] After installation according to the requirements, rubber fibers mixed with rubber particles are added to the separating disc 9. The separating disc 9 is then securely fixed to the top of the feeding disc 7 using the buckle 8. The rotating sleeve 5 is continuously rotated clockwise so that the elastic pull rope 3 is wound around the groove of the rotating sleeve 5. The pull ring at the end of the elastic pull rope 3 is pulled taut by hand and then released after it is fully straightened. Because the inner wall of the rotating sleeve 5 and the outer wall of the stabilizing column 4 are fitted with a clearance fit, and the stabilizing column 4 is fixed to the base plate 1, the stabilizing column 4 can provide stable support and guidance for the rotation of the rotating sleeve 5. During the rotation, the elastic pull rope 3 is wound back around the groove of the rotating sleeve 5 due to inertia. Periodic tension and relaxation are applied to the elastic pull rope 3 to make... The rotating sleeve 5 performs a periodic reciprocating rotational motion. During this motion, the feeding disc 7 and the separating disc 9 move synchronously. As the separating disc 9 moves, rubber fibers mixed with rubber particles begin to roll on it due to inertia and friction. The rubber fibers tend to rotate around their long axis during this rolling motion. Since the length of the rubber fibers is much greater than the screen aperture, they are blocked on the screen. Meanwhile, the rubber particles, due to their smaller diameter than the screen aperture, fall into the feeding disc 7. After the rotation stops, the latch 8 is opened, and the separating disc 9 is removed from the feeding disc 7. The remaining rubber fibers in the separating disc 9 are collected, and the sorted rubber particles collected in the feeding disc 7 are also collected, completing the sorting process.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
