Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a waste crusher for tire production. Background Art

[0002] Tires are an important component of vehicles. They directly contact the ground and support the entire vehicle. The main raw materials of tires are natural rubber and synthetic rubber. In the production process of tires, some defective products are inevitably produced. These defective products may affect the safety performance and service life of the tires. Generally, a crusher is required to crush these waste tires.

[0003] Existing tire crushers cannot perform intermittent crushing operations. Continuously feeding tire waste into the crusher will increase the working intensity of the crushing cutters. Continuous concentrated feeding will lead to poor crushing results and even cause the crushing cutters to get stuck, thereby affecting the crushing operation of the crusher on the waste tires. Therefore, we propose a waste crusher for tire production to solve the above problems. Utility Model Content

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-6 A tire production waste crusher includes a crushing machine body 1 and a tire body 2. The crushing machine body 1 is respectively provided with a feed port 3, a crushing chamber 4 and a discharge port 5. The inner wall of the feed port 3 is respectively provided with two upper movable grooves 6 and two lower movable grooves 7. The two upper movable grooves 6 are movably installed with upper limit blocks 8, and the two lower movable grooves 7 are movably installed with lower limit blocks 9. The tire body 2 is inserted into the feed port 3 and overlapped on the two lower limit blocks 9. The crushing machine body 1 is respectively provided with two rotating chambers 10. The two rotating chambers 10 are rotatably installed with rotating blocks. The two rotating frames 11 are movably connected to the corresponding upper limit block 8 and lower limit block 9 respectively. The crushing body 1 is provided with a rotation drive mechanism for the corresponding rotating frame 11. The rotation drive mechanism includes a rotating motor 12, a first driving rod 13 and a first driving gear 14. The rotating motor 12 is fixedly mounted on one side of the crushing body 1. The output shaft of the rotating motor 12 is fixedly mounted with one end of the first driving rod 13. The other end of the first driving rod 13 rotates and extends to the outside of the crushing body 1 and is fixedly mounted with the first driving gear 14. The rod 13 is fixedly connected to the corresponding rotating frame 11, and can indirectly drive the two rotating frames 11 to rotate synchronously in opposite directions through the rotation driving mechanism; a driven mechanism for the other rotating frame 11 is provided on the crushing machine body 1, and the driven mechanism includes a first driven rod 15, a first driven gear 16, and a connecting gear 17. One end of the first driven rod 15 is rotatably mounted on the inner wall of one side of the corresponding rotating chamber 10, and the other end of the first driven rod 15 is rotatably extended to the outside of the crushing machine body 1 and fixedly mounted with the first driven gear 16. The first driven rod 15 is connected to the corresponding rotating frame 11. The rotating frame 11 is fixedly connected, and two connecting gears 17 are rotatably installed on one side of the crushing body 1. The two connecting gears 17 are meshed with each other, and the sides of the two connecting gears 17 away from each other are meshed with the first driving gear 14 and the first driven gear 16 respectively. Since the first driven gear 16 and the first driving gear 14 are meshed and connected through the two connecting gears 17, when the first driving gear 14 rotates, it can drive the first driving gear 14 and the first driven gear 16 to rotate synchronously in opposite directions; a crushing mechanism is provided in the crushing chamber 4.

[0024] Furthermore, the two upper movable grooves 6 are respectively located on both sides of the feed port 3, and the two lower movable grooves 7 are respectively located on both sides of the feed port 3. The upper movable groove 6 is located above the lower movable groove 7, so that the two upper limit blocks 8 can move closer to each other in the corresponding upper movable grooves 6, and the two lower limit blocks 9 can move closer to each other in the corresponding lower movable grooves 7.

[0025] Furthermore, the upper limit block 8 and the lower limit block 9 on one side of the feed port 3 are arranged in a staggered manner. When the two lower limit blocks 9 extend into the feed port 3, the tire body 2 below is limited. When the two upper limit blocks 8 extend into the feed port 3, the tire body 2 above is limited.

[0026] Furthermore, the two rotating chambers 10 are respectively located on both sides of the feed port 3 , and the two rotating chambers 10 are respectively connected to the corresponding upper movable groove 6 and lower movable groove 7 , so as to facilitate the rotation of the rotating frame 11 in the rotating chamber 10 .

[0027] Furthermore, the crushing mechanism includes a crushing motor 18, a second driving rod 19, a second driving gear 20, a second driven rod 21, a second driven gear 22 and a crushing knife roller 23. The crushing motor 18 is fixedly installed on one side of the crushing body 1, and the output shaft of the crushing motor 18 is fixedly installed with the second driving rod 19. One end of the second driving rod 19 is fixedly installed with the second driving gear 20. One end of the second driven rod 21 is rotatably installed on one side inner wall of the crushing chamber 4. The other end of the second driven rod 21 is rotatably extended to the outside of the crushing body 1 and is fixedly installed with the second driven gear 22. The second driven gear 22 is meshed with the second driving gear 20. The second driving rod 19 and the second driven rod 21 are both fixedly installed with a crushing knife roller 23. The two crushing knife rollers 23 are adapted to each other, and the intermittently fallen tire body 2 is crushed by the crushing mechanism.

[0028] During use: insert the two tire bodies 2 to be crushed into the feed port 3 in sequence, and the lower tire body 2 falls onto the two lower limit blocks 9. The two lower limit blocks 9 limit the lower tire body 2 to prevent the tire body 2 from continuing to slide into the crushing chamber 4. By turning on the rotating motor 12, the first driving rod 13 drives the left rotating frame 11 and the first driving gear 14 to rotate. Since the first driven gear 16 and the first driving gear 14 are meshed and connected by two connecting gears 17, the first driving gear 14 and the first driven gear 16 are synchronously rotated in opposite directions. At this time, the rotating frame 11 on the left rotates clockwise and the rotating frame 11 on the right rotates counterclockwise, thereby synchronously driving the two lower limit blocks 9 away from each other. At the same time, the two upper limit blocks 8 are driven to approach each other until the lower tire body 2 falls into the crushing chamber 4, and the upper tire body 2 is limited between the two upper limit blocks 8 to prevent the upper tire body 2 from continuing to fall, thereby achieving the purpose of intermittent unloading, avoiding the increase in the working intensity of the crushing roller 23 due to continuous unloading, reducing the phenomenon of the crushing roller 23 getting stuck, and ensuring the normal crushing operation of the crusher body 1 on the tire body 2. At the same time, by turning on the crushing motor 18, the second drive rod 19 drives the second drive gear 20 to rotate. Since the second drive gear 20 is engaged with the second driven gear 22, the two crushing rollers 23 are driven to rotate to realize the crushing operation of the intermittently falling tire body 2.
