Description

Technical Field

[0001] The invention relates to the technical field of waste tire recycling, in particular to a steel wire separation device for recycling waste tires. Background Art

[0002] As the number of cars in today's society has been rising year by year, the demand for tire replacement has increased, causing the problem of increasing pressure on the recycling of waste tires. The components of waste tires are difficult to degrade, and long-term stacking threatens soil and water sources. At the same time, waste tires are flammable, and open-air stacking is prone to fire, which seriously threatens the surrounding environment and the safety of life and property of residents. Since the main components of tires are composed of rubber and steel wires with recycling value, the existing technology for processing waste tires is usually to separate rubber and steel wire for recycling and reuse. The existing device for separating waste tires only uses two rollers rotating in opposite directions to crush the rubber on the outer layer of the waste tire, and then obtains the steel wire of its inner layer. However, when separating the waste tires, the existing technology can only make the waste tires enter and exit from one side, that is, feed from the left side of the roller and crush the rubber, and then discharge from the left side of the roller to complete the collection of the steel wire. This type of crushing and separation method has the problem of low efficiency in separating the rubber and steel wire of waste tires, and also requires staff to manually control the feeding and discharging, resulting in high labor costs.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of the present invention is proposed, which provides a wire separation device for recycling waste tires to solve the problem that the existing wire separation device has one-sided loading and unloading, resulting in extremely low wire separation efficiency and high manpower consumption cost. The device includes: a base frame 1; two rotating shafts 2, both of which are rotatably connected to the base frame 1, and the two are connected by a spur gear set, one of the rotating shafts 2 is connected by a transmission connection with an output shaft of an external motor; separation rollers 3, the number of which is the same as the number of rotating shafts 2, and are respectively arranged on adjacent rotating shafts 2; support rods 4, fixedly connected to the base frame 1; support cylinders 5, fixedly connected to the support rods 4; auger rods 6, the number of which is more than one, all of which are rotatably connected between the base frame 1 and the support cylinder 5, and the auger rods 6 are connected to adjacent rotating shafts 2 by a pulley belt transmission; a cutting mechanism, which is arranged on the upper side of the base frame 1, and is used to cut the steel wire peeled off from the tire bead 101.

[0019] In the above scheme, there are three auger rods 6, which are distributed in a triangular shape and are used to stably support and transport the tire bead 101. When separating the steel wire in the tire bead 101, the rear rotating shaft 2 is driven by a motor to rotate, and the rear rotating shaft 2 drives the front rotating shaft 2 to rotate together through the spur gear set, and the rotating shaft 2 drives the separation roller 3 to rotate together, and one of the rotating shafts 2 drives the three auger rods 6 to rotate together through the pulley belt, and then the tire bead 101 is placed on the support tube 5, and then the tire bead 101 is pushed to the left (such as Figure 3 Taking the direction shown as an example), after the tire bead 101 contacts the rotating auger rod 6, the auger rod 6 drives the tire bead 101 to move to the left and contact with the two rotating separation rollers 3, and then the tire bead 101 moves to the left between the two rotating separation rollers 3. During the process, the two separation rollers 3 squeeze and tear the tire bead 101, and the rubber layer on the outside of the tire bead 101 is gradually broken, so that the steel wire inside is exposed, thereby completing the separation of the rubber and steel wire on the tire bead 101. During the separation process, the tire bead 101 continues to move to the left under the action of the separation rollers 3 The support cylinder 5 is moved until the tire bead 101 (the steel wire after the rubber layer is peeled off) is separated from the separation roller 3. During the process, a new tire bead 101 is continuously added to the support cylinder 5, so that each tire bead 101 is broken one by one in turn, so that the steel wire separation process is continuous, avoiding the low efficiency of separating the steel wire in the tire bead 101 by using the single-side feeding and discharging method of the existing separation technology, and reducing the operation steps of the staff to control the feeding and discharging, reducing the work intensity of the staff, and after the separated steel wire moves to the cutting mechanism area, the cutting mechanism cuts the steel wire and discharges the steel wire from the device.

[0020] like Figure 1 and Figure 2 As shown, the cutting mechanism includes: a bracket 701, fixedly connected to the base frame 1; a cutting knife 702, slidably connected to the bracket 701; a limiting frame 703, fixedly connected to the auger rod 6 near the cutting knife 702, the bracket 701 is slidably connected with an extrusion block 704, a tension spring is fixedly connected between the bracket 701 and the extrusion block 704, the extrusion block 704 is extruded and matched with the limiting frame 703, the cutting knife 702 and the extrusion block 704 are provided with inclined surfaces on the opposite sides, the two inclined surfaces are extruded and matched, an elastic element 705 is fixedly connected between the bracket 701 and the cutting knife 702, the bracket 701 is fixedly connected with a docking piece, and the docking piece is in contact and matched with the cutting knife 702.

[0021] In the above scheme, the limit frame 703 is provided with an inclined surface, which is extruded and matched with the extrusion block 704. The elastic element 705 is a tension spring, which is used to reset the cutting knife 702. During the rotation of the auger rod 6, one of the auger rods 6 drives the limit frame 703 to rotate together. When the limit frame 703 rotates to contact with the extrusion block 704, the extrusion block 704 moves to the right and squeezes the cutting knife 702. During the process, the extrusion block 704 stretches the tension spring, and the cutting knife 702 begins to slide downward along the bracket 701. The elastic element 705 is stretched. During the process, the cutting knife 702 gradually contacts the docking piece and cuts off the tire bead 101 (the remaining steel wire after the rubber is stripped) that moves to the area, thereby reducing the operating steps of the staff, reducing labor costs and improving the efficiency of steel wire separation.

[0022] like Figure 1 and Figure 3-Figure 5 As shown, it also includes: a limit frame 8, which is fixedly connected to the base frame 1, and the inner diameter of the limit frame 8 is gradually changed, which is used for limiting and squeezing the tire bead 101; a scraper 801 is fixedly connected inside the limit frame 8, which is used for scraping the tire bead 101; it also includes: a jacket 901, which is fixedly connected to the base frame 1, and the support tube 5 is located inside the jacket 901; an extrusion member 902, which is fixedly connected to the jacket 901, and a bending area is provided on the extrusion member 902; it also includes: a first elastic member 1001 and a second elastic member 1002, which are respectively arranged on adjacent separation rollers 3, and the two are in contact and fit; the first elastic member 1001 and the second elastic member 1002 are equal in length on their own axes, and both are provided with inclined surfaces on the side close to the jacket 901.

[0023] In the above scheme, the inner diameter of the limit frame 8 gradually decreases from right to left, and is used to squeeze the tire bezel 101 and remove the rubber debris after peeling to ensure the cleanliness of the separated steel wire. The extrusion pieces 902 are distributed circumferentially at intervals, and the opposite sides of the multiple extrusion pieces 902 are bent inward (i.e., the above-mentioned bending area), so as to uniformly squeeze the tire bezel 101 and make the tire bezel 101 become a "cylindrical" shape. The first elastic piece 1001 and the second elastic piece 1002 are both made of rubber. When the tire bezel 101 moves leftward on the support tube 5, During the process, when the tire ring 101 moves to the left until it contacts the extrusion piece 902, the extrusion piece 902 blocks the outer ring area of ​​the tire ring 101, and the inner ring of the tire ring 101 continues to move to the left, and the tire ring 101 is deformed and gradually becomes a "cylindrical" shape, thereby preventing the tire ring 101 from being squeezed and crushed. The tire ring 101 is squeezed to produce wrinkles, causing the two separation rollers 3 to squeeze the multi-layer steel wire, causing the steel wire to deform, thereby reducing the recycling value of the steel wire and even affecting the subsequent further processing of the steel wire.

[0024] When the tire bead 101 moves to contact the first elastic member 1001 and the second elastic member 1002, the first elastic member 1001 and the second elastic member 1002 clamp the tire bead 101 (in a state after basic separation), and then the tire bead 101 starts to rotate. During the process, the scraper 801 continuously scrapes the tire bead 101 to remove the rubber adhered to the steel wire, thereby improving the separation effect of the steel wire.

[0025] like Figure 1 , Figure 5-Figure 8 As shown, it also includes: a support frame 1101, which is fixedly connected to the base frame 1, and the rotating shaft 2 and the separation roller 3 near the support frame 1101 are limitedly slidably connected, the inner ring of the first elastic member 1001 is provided with a fixed frame, and the fixed frame is fixedly connected to the adjacent rotating shaft 2, the support frame 1101 is installed with a first bevel gear set 1102, and the first bevel gear set 1102 and the adjacent rotating shaft 2 are connected through a pulley belt transmission; a sliding block 1103, which is slidably connected to the support frame 1101; an adjusting component, which is arranged on the support frame 1101; a connecting rod 1104, which is hinged between the first bevel gear set 1102 and the sliding block 1103 through the adjusting component, and the adjusting component is used to adjust the position of the connecting rod 1104 at the "hinge point" on the first bevel gear set 1102; a moving ring 1105, which is fixedly connected to the sliding block 1103, and the moving ring 1105 is limitedly rotatably connected to the adjacent separation roller 3.

[0026] In the above scheme, the first bevel gear set 1102 is composed of a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear and the second bevel gear are both rotatably connected to the support frame 1101. The second bevel gear is connected to the adjacent rotating shaft 2 through a pulley belt transmission. The connecting rod 1104 is hinged between the first bevel gear and the sliding block 1103. The connecting rod 1104 is hinged at the eccentric point on the first bevel gear. During the rotation of the rotating shaft 2, the rotating shaft 2 is transmitted to the second bevel gear through the pulley belt, and the second bevel gear drives the first bevel gear to rotate. The first bevel gear is connected through the adjusting component The connecting rod 1104 is driven to move, and the connecting rod 1104 drives the sliding block 1103 to move together. The sliding block 1103 and the support frame 1101 slide relative to each other, and the sliding block 1103 drives the adjacent separation rollers 3 to move together through the moving ring 1105, so that the two separation rollers 3 move relative to each other and "knead" the tire bead 101 between them, thereby reducing the adhesion between the rubber and the steel wire, thereby improving the separation effect of the rubber layer and the steel wire on the tire bead 101, and reducing the difficulty of subsequent reprocessing of the obtained steel wire (separated from the tire bead 101).

[0027] like Figure 5-Figure 8As shown, the adjustment component includes: a knob 1201, which is rotatably connected to the support frame 1101; a threaded rod 1202, which is rotatably connected to the first bevel gear set 1102; the threaded rod 1202, which is slidably connected to the first bevel gear set 1102, a slider 1203 is threadedly connected to the threaded rod 1202, the slider 1203 is hinged to the connecting rod 1104, and a second bevel gear set 1204 is arranged between the threaded rod 1202 and the knob 1201; a one-way bearing is arranged between the second bevel gear set 1204 and the knob 1201, which is used to enable the two to move relative to each other.

[0028] In the above scheme, the second bevel gear set 1204 is composed of a third bevel gear and a fourth bevel gear that mesh with each other. The third bevel gear is fixedly connected to the threaded rod 1202, and the fourth bevel gear is connected to the knob 1201 through a one-way bearing. When it is necessary to adjust the relative sliding distance between the sliding block 1103 and the support frame 1101, the knob 1201 is turned, and the knob 1201 drives the fourth bevel gear to rotate together through the one-way bearing. The fourth bevel gear drives the threaded rod 1202 to rotate together through the third bevel gear. Under the action of the threaded rod 1202, the sliding block 1203 slides relative to the first bevel gear, thereby adjusting the "hinge point" of the connecting rod 1104 on the first bevel gear, thereby changing the relative sliding distance between the sliding block 1103 and the support frame 1101, thereby increasing the scope of application of the device.
