A scrapped car tire recycling device

Abstract

This invention discloses a device for recycling scrapped car tires. In use, the hollow portion of the tire to be recycled is placed onto a rolling device from the side of the mounting frame. The clamping plate is adjusted to contact both sides of the tire, and then the bolts are tightened to secure the clamping plate. After the tire is in place, the metal cutting wire is heated by electricity, and the first motor is turned on. Simultaneously, the lifting device moves downwards to cut the tire. When the adjusting foot touches the operating table, the first active roller drives the tire to rotate, and the metal cutting wire performs a circumferential cut on the tire sidewalls, cutting the tire into a tread with more dirt and two annular sidewalls with less dirt. The tread is subsequently transported to a water tank and washed with a brushing device, while the sidewalls can be manually rinsed or brushed. This method has low cost, good cleaning effect, and provides a more efficient processing method for tire recycling.

Description

Technical Field

[0001] This invention relates to the field of automobile recycling, and more particularly to a device for recycling end-of-life automobile tires. Background Technology

[0002] Waste tires are difficult to process, difficult to degrade, and have nowhere to be stored. Because tires are used to support tens of tons of weight to keep running, the rubber used in tires is of much higher quality than that used in other rubber products. Tire rubber must be wear-resistant, prevent aging, be waterproof, and have shock absorption capabilities. Therefore, discarding waste tires as garbage is a huge waste of resources. If waste tires are physically crushed and processed, rubber granules, rubber powder, and steel wire can be obtained. These rubbers can be used in many fields, such as roadbed paving, rubber running tracks, and various rubber products.

[0003] Before recycling and processing waste tires, they need to be cleaned to facilitate subsequent operations. Current cleaning equipment struggles to thoroughly clean tires. Existing patent CN201710281963 discloses a cleaning device for automobile tire recycling. This device places waste tires on a placement plate, clamps them, and then uses a high-pressure nozzle to clean them. During cleaning, a left-right movement device moves the high-pressure nozzle left and right, and the placement plate can be rotated to rotate the waste tires, thus achieving a more comprehensive cleaning. However, because tires develop cracks in the tread during use, a large amount of sand and gravel becomes trapped within these cracks. High-pressure water cleaning can only remove sand and gravel trapped in the tread surface. Furthermore, because tires are made of rubber and have a certain degree of elasticity, the sand and gravel in the cracks are encased in the tire and move with the water's impact during high-pressure water cleaning, making it impossible to completely remove the sand and gravel. Direct crushing can damage the shredder blades. Additionally, when collecting the steel wires and wire mesh layers inside the tire, high-completeness recycling is not achieved, resulting in residual steel wires adhering to the tire during later crushing.

[0004] In addition, this type of device, which uses water rinsing to clean the tires before recycling, has drawbacks such as high water consumption, incomplete cleaning, and easy splashing that pollutes the working environment. Summary of the Invention

[0005] To address the aforementioned problems with existing tire recycling devices, largely due to the fact that tires are three-dimensional objects and inconvenient to process, it would be much easier and more energy-efficient to clean tires if they could be properly cut and sorted beforehand. To achieve this technical objective, this invention proposes a scrapped car tire recycling device, comprising: a wire cutting device for cutting a tire into a tread and two annular sidewalls, and a brushing device for cleaning the tread; the wire cutting device includes a wire cutting assembly, an adjusting device for driving the wire cutting assembly to complete horizontal and vertical movement, and an operating table for upright placement and rotation of the tire; the brushing device is located on one side of a water tank and includes a U-shaped plate for placing and rotating the tread, a support column for supporting the U-shaped plate, and a brush head that reciprocates above the U-shaped plate.

[0006] Preferably, the wire cutting assembly includes: a strip-shaped housing, a first motor mounted at one end of the housing, a slide rail inside the housing, the shaft of the first motor driving a slider to reciprocate in the slide rail via a crank-connecting rod mechanism fixed inside the housing; outer legs on both sides of the lower part of the housing, inner legs on both sides of the lower part of the slider, the lower parts of the two inner legs being connected by a metal cutting wire, the inner legs reciprocating within the inner cavity of the outer legs, and the lower parts of the two outer legs having wire holes for the metal cutting wire.

[0007] Preferably, one side of the slider is provided with a socket, and the slider is provided with a wire. The wire, the metal cutting wire, and the socket form a circuit. The metal cutting wire serves as a heating wire, and its surface is treated with a frosted finish.

[0008] Preferably, both ends of the metal cutting wire are fixed to the conductive block by welding or wrapping. The conductive block is screwed into the screw hole at the bottom of the inner support foot and forms an electrical connection with the wire by clamping, which facilitates the replacement of the metal cutting wire. The front of the outer casing has a strip groove to accommodate the socket.

[0009] Preferably, the operating table has two parallel longitudinal rails with an inverted T-shaped cross section. Each rail has two opposing clamps, which are also inverted T-shaped. The bottom of each clamp has a positioning hole on the outer side. The clamps are fixed to a certain position within the rail by adjusting bolts. On each side perpendicular to the rail direction, there is a rolling device for rolling the tire. The upper part of the rolling device is a cylindrical surface that fits the tire tread. A first active roller protrudes from the cylindrical surface within the cylindrical area. The rolling device contains a stepper motor, and the shaft of the stepper motor drives the first active roller to rotate through gear transmission.

[0010] Preferably, the bottom of the outer support leg is provided with an adjustable foot.

[0011] Preferably, the scrubbing device includes a support column, side columns, a U-shaped plate, a second motor, a third motor, a brush head, and a second drive roller; the support column is 7-shaped, with its lower part located at the edge of the pool and its upper part extending above the pool. A U-shaped plate is installed at the upper end of the support column, and the second drive roller is installed in the groove of the U-shaped plate. The second motor is installed on the upper part of the support column, and the shaft of the second motor passes through one side of the U-shaped plate to drive the second drive roller to rotate. An L-shaped side column is installed on one side of the upper part of the support column, and a third motor is installed on the side column. The third motor drives the brush head to perform reciprocating linear motion, and the brush head is located above the U-shaped plate.

[0012] Preferably, the first motor is a high-speed motor, the second motor is a stepper motor, and the third motor is a reciprocating linear motor.

[0013] Preferably, the positioning device includes a 7-shaped mounting frame, with a lifting device installed under the crossbeam of the mounting frame, which drives the outer casing to move up and down.

[0014] Preferably, the groove of the U-shaped plate is arched, and the direction of movement of the brush head forms a 45° angle with the direction of the groove of the U-shaped plate.

[0015] In this invention, the hollow part of the tire to be recycled is placed onto the rolling device from the side of the mounting frame, and the clamp is adjusted to contact the sides of the tire. Then, the bolts are tightened to fix the clamp. After the tire is in place, the metal cutting wire is heated by electricity, and the first motor is turned on. At the same time, the lifting device moves downward to cut. When the adjusting foot touches the operating table, the first active roller drives the tire to rotate, and the metal cutting wire performs a ring cut on the side of the tire, cutting the tire into a tread with more dirt and two annular sides with less dirt. The tread is then transported to the edge of the water pool and washed with water by a brushing device. The sides can be rinsed or brushed manually. This method has low cost, good cleaning effect, and provides a more efficient processing method for tire recycling. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-7 As shown, the scrapped car tire recycling device of the present invention includes: a wire cutting device 1 for cutting the tire into a tread and two annular sidewalls, and a brushing device 2 for cleaning the tread; the wire cutting device 1 includes a wire cutting assembly, an adjustment device for driving the wire cutting assembly to complete horizontal and vertical movement, and an operating table 18 for upright placement and rotation of the tire; the brushing device 2 is located on one side of the water tank and includes a U-shaped plate 22 for placing and rotating the tread, a support column 21 for supporting the U-shaped plate 22, and a brush head 25 that reciprocates above the U-shaped plate 22.

[0026] More specifically, the wire cutting assembly includes: a strip-shaped housing 13, with a first motor 15 mounted at one end of the housing 13, and a slide rail inside the housing 13. The shaft of the first motor 15 drives the slider 14 to reciprocate in the slide rail via a crank-connecting rod mechanism 17 fixed inside the housing 13. The crank-connecting rod mechanism 17 is a structure commonly used in the mechanical industry for converting between rotary motion and reciprocating linear motion, such as the needle of a sewing machine and the engine of a car. In this case, it is used to drive the slider 14 to perform high-speed reciprocating motion to achieve the cutting action. The housing 13 has outer legs 16 on both sides of its lower part, and the slider 14 has inner legs 142 on both sides of its lower part. The lower parts of the two inner legs 142 are connected by a metal cutting wire 143. The inner legs 142 reciprocate in the inner cavity of the outer legs 16, and the lower parts of the two outer legs 16 have wire holes to accommodate the metal cutting wire 143.

[0027] More specifically, the slider 14 has a socket 144 on one side, and a wire 141 is provided inside the slider 14. The wire 141, the metal cutting wire 143, and the socket 144 form a circuit. The metal cutting wire 143 serves as a heating wire, and its surface is sanded. In addition to sanding, other surface roughening treatments can be performed to facilitate cutting. The cutting wire is not only used as a cutting knife but also as a thermoforming unit, making it easier to cut the rubber tires it contacts.

[0028] More specifically, both ends of the metal cutting wire 143 are fixed to the conductive block 145 by welding or wrapping. The conductive block 145 is screwed into the screw hole at the bottom of the inner support leg 142 and forms an electrical connection with the wire 141 by clamping. Since the metal cutting wire 143 is a consumable in this invention and needs to be replaced frequently, this design facilitates the replacement of the metal cutting wire 143. The front of the outer shell 13 has a strip groove to accommodate the socket 144.

[0029] More specifically, the operating table 18 has two parallel longitudinal rails 181 with inverted T-shaped longitudinal sections. Each rail 181 has two opposing clamping plates 182. The clamping plates 182 are inverted T-shaped, and positioning holes are provided on the outer side of the bottom of the clamping plates 182. The clamping plates 182 are fixed to a certain position in the rail 181 by adjusting bolts. On each side perpendicular to the direction of the rail 181, there is a rolling device 183 for rolling the tire. The upper part of the rolling device 183 is a cylindrical surface that fits the tire tread. A first active roller 184 protruding from the cylindrical surface is provided in the area of ​​the cylindrical surface. A stepper motor is provided in the rolling device 183. The shaft end of the stepper motor drives the first active roller 184 to rotate through gear transmission. In this case, the function of the clamping plates 182 is to prevent the tire from moving laterally and falling out of the rolling device 183 during the cutting process, rather than clamping the tire, because the tire still needs to rotate to achieve circumferential cutting and cut off the two sides of the tire tread.

[0030] More specifically, the bottom of the outer support leg 16 is provided with an adjusting foot 19. In this example, the adjusting foot 19 is a common type with a screw at the top. By screwing in the adjusting foot 19 to adjust the height of the support leg, this component is used to adjust the distance from the cutting line to the operating table 18. This distance is determined according to the thickness of the tire tread.

[0031] More specifically, the scrubbing device 2 includes a support column 21, a side column 23, a U-shaped plate 22, a second motor 27, a third motor 24, a brush head 25, and a second drive roller 26. The support column 21 is 7-shaped, with its lower part located at the edge of the pool and its upper part extending above the pool. The upper end of the support column 21 is fitted with a U-shaped plate 22, and the second drive roller 26 is installed in the groove of the U-shaped plate 22. The second motor 27 is mounted on the upper part of the support column 21, and the shaft of the second motor 27 passes through one side of the U-shaped plate 22 to drive the second drive roller 26 to rotate. The upper part of the support column 21 is equipped with an L-shaped side column 23, and a third motor 24 is mounted on the side column 23. The third motor 24 drives the brush head 25 to perform reciprocating linear motion. The brush head 25 is located above the U-shaped plate 22. In this case, the U-shaped plate 22 is used to suspend the tire tread and rotate it, and incidentally wet it. Then, the brush head 25 driven by the third motor 24 is used to clean the tire. The first active roller 184 and the second active roller 26 are both used to drive the tire to rotate. Therefore, their outer walls are provided with anti-slip layers. In this example, rubber is used for wrapping and anti-slip texture is provided.

[0032] More specifically, the first motor 15 is a high-speed motor, the second motor 27 is a stepper motor, and the third motor 24 is a reciprocating linear motor.

[0033] More specifically, the positioning device includes a 7-shaped mounting frame 11, with a lifting device 12 mounted under the crossbeam of the mounting frame 11, which drives the outer casing 13 to move up and down.

[0034] More specifically, the groove of the U-shaped plate 22 is arched, and the direction of movement of the brush head 25 is at a 45° angle to the direction of the groove of the U-shaped plate 22. This positional design allows the brush head 25 to clean both the axial and circumferential aspects of the tire tread during brushing. To prevent the tire tread from shifting circumferentially due to the brush head 25 during brushing, a tension roller 28 is also provided below the water surface in this example.

[0035] Furthermore, it should be noted that in this invention, the lifting device, reciprocating linear motor, stepper motor, etc. are all existing products and technologies. Their connection, fixing methods, structures, operating principles, and functions are well known to those skilled in the art. The electrical devices involved in this case, such as the lifting device, the first motor, the second motor, etc., all include controllers for controlling the operation of the above-mentioned devices. In summary, the technical solution described in this case is clear and complete.

[0036] In this invention, the hollow part of the tire to be recycled is placed onto the rolling device from the side of the mounting frame, and the clamp is adjusted to contact the sides of the tire. Then, the bolts are tightened to fix the clamp. After the tire is in place, the metal cutting wire is heated by electricity, and the first motor is turned on. At the same time, the lifting device moves downward to cut. When the adjusting foot touches the operating table, the first active roller drives the tire to rotate, and the metal cutting wire performs a ring cut on the side of the tire, cutting the tire into a tread with more dirt and two annular sides with less dirt. The tread is then transported to the edge of the water pool and washed with water by a brushing device. The sides can be rinsed or brushed manually. This method has low cost, good cleaning effect, and provides a more efficient processing method for tire recycling.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
