Description

Technical Field

[0001] This utility model relates to the field of steel wire separator blade technology, and in particular to a steel wire separator blade roller equipped with double-sided blades. Background Technology

[0002] To ensure sufficient strength and durability, tires use high-performance rubber and steel wire as a skeleton. This means that during waste tire recycling, the main rubber material cannot be processed directly; the internal steel wire must first be separated. The separation process typically uses a steel wire separator, which has a rotating cutter roller with blades mounted on its surface. During rotation, the roller cuts, rolls, and squeezes the tire, breaking down the rubber material and separating it from the steel wire.

[0003] However, in addition to acting on the rubber material, the cutters on the cutter roller inevitably experience continuous pulling, scraping, and friction with the steel wire, causing their edges to gradually become dull and reducing their cutting efficiency on the rubber material. Traditional cutters have an assembly structure at the bottom for tight assembly with the cutter roller; once the cutter becomes dull, it needs to be replaced with a new one, resulting in excessively high maintenance costs. Utility Model Content

[0004] This utility model discloses a wire separator cutter roller equipped with double-sided cutters, comprising:

[0005] Shaft 1, tool holder 2 mounted on shaft 1, double-sided tool 5 mounted on tool holder 2, wedge 3 mounted on the side of double-sided tool 5, and cover 4 mounted on the surface of tool holder 2.

[0006] A filler 31 is assembled between the double-sided cutting tool 5 and the wedge 3;

[0007] The double-sided cutting tool 5 has cutting teeth 51 on both sides.

[0008] Preferably, the tool holder 2 has a deep groove 21 and a shallow groove 22;

[0009] The double-sided cutter 5 is assembled in the deep groove 21, and the wedge 3 is assembled in the shallow groove 22.

[0010] Preferably, the cross-section of the wedge 3 is an inverted trapezoid, with the width at the top being greater than the width at the bottom.

[0011] Preferably, the cross-section of the filler 31 is trapezoidal, with the width of its top being smaller than the width of its bottom.

[0012] Preferably, the wedge 3 secures and limits the filling material 31, and the filling material 31 presses against the double-sided cutter 5 and the wedge 3, so that the double-sided cutter 5 is securely assembled in the deep groove 21.

[0013] Preferably, the cover 4 has an inverted trapezoidal cross section, with its hypotenuse limiting the wedge 3 so that the wedge 3 is securely fitted into the shallow groove 22.

[0014] Preferably, the wedge 3 and the cover 4 are fastened to the tool holder 2 by bolts.

[0015] Preferably, adjacent double-sided cutting tools 5 are arranged alternately in the axial direction of the shaft 1.

[0016] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0017] The tool uses a double-sided cutting tool without an assembly structure, and is fastened to the tool holder with a wedge and a cover. When one side of the double-sided cutting tool becomes dull, it can be swapped and installed, and the sharp side can continue to be used for operation, which greatly reduces the cost of use and maintenance.

[0025] Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-2 The wire separator cutter roller equipped with double-sided cutters may include the following.

[0028] Shaft 1, tool holder 2 mounted on shaft 1, double-sided tool 5 mounted on tool holder 2, wedge 3 mounted on the side of double-sided tool 5, and cover 4 mounted on the surface of tool holder 2.

[0029] A filler 31 is assembled between the double-sided cutting tool 5 and the wedge 3;

[0030] The double-sided cutter 5 has cutting teeth 51 on both sides.

[0031] Here, a double-sided cutter 5 without an assembly structure is used, and it is fastened to the cutter holder 2 by a wedge 3 and a cover 4. When one side of the double-sided cutter 5 becomes dull, it can be swapped and installed, and its sharp side can continue to be used for operation, which greatly reduces the cost of use and maintenance.

[0032] In this embodiment, the tool holder 2 has a deep groove 21 and a shallow groove 22;

[0033] The double-sided cutting tool 5 is assembled in the deep groove 21, and the wedge 3 is assembled in the shallow groove 22.

[0034] In this embodiment, the cross-section of the wedge 3 is an inverted trapezoid, with the width of its top being greater than the width of its bottom.

[0035] In this embodiment, the cross-section of the filler 31 is trapezoidal, and the width of its top is smaller than the width of its bottom.

[0036] In this embodiment, the wedge 3 secures and limits the filler 31, and the filler 31 presses against the double-sided cutter 5 and the wedge 3, so that the double-sided cutter 5 is securely assembled in the deep groove 21.

[0037] Here, the filler can be a high-density elastic material to ensure that the cutting tool and the double-sided blade do not cause structural damage to each other due to direct contact, thereby improving service life and providing better limiting and clamping performance.

[0038] In this embodiment, the cross-section of the cover 4 is an inverted trapezoid, and its hypotenuse limits the wedge 3, so that the wedge 3 is securely assembled in the shallow groove 22.

[0039] In this embodiment, the wedge 3 and the cover 4 are fastened to the tool holder 2 by bolts.

[0040] Here, there is no connecting structure between the tool holder and the double-sided cutter. The double-sided cutter is held in place in the deep groove by a wedge and filler, and the wedge is further held in place by the cover, thus ensuring that the double-sided cutter can still be installed securely in high-intensity operations even without a rigid connection with the tool holder.

[0041] Meanwhile, the above installation method of double-sided cutters also facilitates the subsequent disassembly and assembly of double-sided cutters. Only the cover and wedge on the surface need to be removed to take out the double-sided cutter, without the need for the heavy physical disassembly work of the joint between the cutter roller and the cutter as with traditional cutters, which greatly reduces the amount of maintenance work.

[0042] In this embodiment, adjacent double-sided cutting tools 5 are arranged alternately along the axial direction of the shaft 1.

[0043] Here, the staggered double-sided blades ensure that the rubber material is cut evenly, avoiding dead angles in the cut.

[0044] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0045] The tool uses a double-sided cutting tool without an assembly structure, and is fastened to the tool holder with a wedge and a cover. When one side of the double-sided cutting tool becomes dull, it can be swapped and installed, and the sharp side can continue to be used for operation, which greatly reduces the cost of use and maintenance.
