DETAILED DESCRIPTION

[0014] The tire strip cutting machine of the present invention is structured as follows: Figure 1 and Figure 2 As shown, both ends of the upper roller 23 and the lower roller 24 are mounted on the frame 21 through the left fixing seat 4 and the right fixing seat 5 , the upper roller 23 is mounted with an upper blade 26 , and the lower roller 24 is mounted with a lower blade 25 .

[0015] like Figure 3As shown, the upper roller 23 and the lower roller 24 include a roller 6 and a permanent magnet motor 1 and a reducer 2 installed inside the roller 6. The permanent magnet motor 1 is installed on the right side of the roller 6. The right end of the permanent magnet motor housing 14 of the permanent magnet motor 1 is fixedly connected to the right fixed seat 5. The right end of the motor shaft 8 of the permanent magnet motor 1 is located in the center hole of the right fixed seat 5. A bearing 18 is installed between the motor shaft 8 and the right fixed seat 5. An end plate 16 is installed between the outer side of the right fixed seat 5 and the right end of the roller 6. The end plate 16 is fixed to the roller 6 by bolts 15. A bearing 18 is provided between the outer side of the right fixed seat 5 and the end plate 16. The reducer 2 is installed on the left side of the roller 6. A connecting plate 3 is installed at the left end of the machine casing 14, and the connecting plate 3 is fixedly connected to the right end of the left fixed seat 4. The reducer input shaft 12 is located in the center hole of the left fixed seat 4, and the right end of the reducer input shaft 12 passes through the connecting plate 3 and is connected to the motor shaft 8 through a coupling 19. A key 20 is provided on the reducer housing 9, and a keyway is provided on the inner side of the roller 6 at a position corresponding to the key 20. The reducer housing 9 is connected to the roller 6, and the reducer housing 9 is an internal gear structure. The reducer housing 9 is meshed and installed with the gear 10 of the reducer. The left end of the reducer housing 9 is fixed to the roller 6 by a fixing bolt 15, and a bearing 18 is installed between the outside of the left fixed seat 4 and the reducer housing 9.

[0016] Working principle: The permanent magnet motor 4 is powered and rotates, and the power is transmitted to the reducer input shaft 12 of the reducer 2 through the motor shaft 8 and the spline coupling 19. The gear 10 of the reducer 12 is decelerated, and the torque is amplified, so that the upper roller 23 and the lower roller 24 rotate in opposite directions. The upper roller 23 and the lower roller 24 respectively drive the upper blade 26 and the lower blade 25 to perform rotational shearing movement. The tire top and sidewall rubber blocks enter the machine from the feed port 22, and the upper blade 26 and the lower blade 25 rotate to shear the tire top and sidewall, so that the tire top and sidewall are changed from block to strip.

[0017] The rotation principle of the roller 6: the permanent magnet motor stator 17 is fixed on the permanent magnet motor housing 14. After power is turned on, the permanent magnet motor rotor 7 rotates due to the magnetic field force. The rotor 7 is connected to the reducer input shaft 12. The reducer input shaft 12 drives the two gears 10 to rotate through the eccentric sleeve 11. The gears 10 mesh with the internal teeth of the reducer housing 9, thereby driving the reducer housing 9 to rotate. Since the reducer housing 9 is connected to the roller 6 through the key 20 and the fixing bolt 15, the roller 6 is driven to rotate when the reducer housing 9 rotates. The left fixed seat 4 and the right fixed seat 5 are connected to the reducer housing 9 and the roller 6 through the bearing 18, and do not rotate with it. During operation, the left fixed seat 4 and the right fixed seat are fixed. The permanent magnet motor is used to provide power, and the permanent magnet motor is placed inside the roller to reduce the floor space, which is more simple and beautiful. In addition, the permanent magnet motor has a relatively high efficiency in terms of power utilization and is more energy-saving. It adopts a reducer with small tooth difference, and the reducer is also placed inside the roller with a diameter of 400mm and a length of 400mm, thus achieving a large transmission ratio of 1:30 in such a small space.

[0018] The tire strip cutting machine of the present invention has the following advantages over the existing tire strip cutting machine: (1) The innovation of the prime mover power is that a permanent magnet motor is used to provide power, and the roller speed can be adjusted as needed. The permanent magnet motor is placed inside the roller to reduce the floor space, making it more concise and beautiful. In addition, the permanent magnet motor has a relatively high efficiency in terms of power utilization and is more energy-saving; (2) A small-tooth-difference reducer is used for transmission, and the reducer is also placed inside the roller, so that a large transmission ratio of 1:30 is achieved in a small space. While ensuring a large transmission ratio, the overall beauty of the machine body is achieved; (3) The overall appearance is simple, the floor space is small, and maintenance and management are more convenient.
