When the required distance is reached, the measuring sensor will send a signal to the control, the transmission wheel will stop rotating, and the cylinder will drive the cutting head to move downward, thereby cutting the steel belt. However, when the steel belt is cut, it will be affected by the force of the cutting head, thereby causing movement, which will cause inaccurate cutting, so it needs to be modified and optimized.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a fixed-length cutting device for steel strip production, comprising a support 1 and a table 2, wherein the table 2 is fixedly arranged above the support 1;

[0023] A U-shaped bracket 12 is fixedly installed on the top of the table 2, a fixing frame 17 is fixedly installed on the top of the U-shaped bracket 12, a convex gear 19 is rotatably installed on the top of the fixing frame 17, a threaded rod 18 is fixedly installed on the bottom of the convex gear 19, the bottom of the threaded rod 18 passes through the upper and lower sides of the U-shaped bracket 12, a gear 2 16 is fixedly sleeved on the top of the threaded rod 18, and the gear 2 16 is rotatably connected to the U-shaped bracket 12, a fixing block 23 is fixedly installed on the top of the U-shaped bracket 12, and a convex gear 2 2 is rotatably installed on one side of the fixing block 23 2. The convex gear 22 is meshed with the convex gear 19. A transmission rod 24 is fixedly installed on one side of the convex gear 22. The transmission rod 24 passes through the left and right sides of the fixed block 23. The upper threaded sleeve of the threaded rod 18 is threadedly connected with a threaded sleeve 20. The bottom of the threaded sleeve 20 is fixedly installed with a lower pressure plate 21. There are two convex gears 22, which are respectively arranged at both ends of the transmission rod 24. There are two convex gears 19, the fixing frame 17, the threaded rod 18 and the threaded sleeve 20, which are evenly distributed at both ends of the U-shaped bracket 12.

[0024] When the staff uses it, the staff starts the device through the controller. After the device is started, the steel belt is laid flat on the top of the device. When the steel belt passes under the distance sensor 29, the distance sensor 29 will start to calculate the length of the steel belt. When the steel belt needs to be cut, the controller starts the motor 2 14 to drive the rotation of the gear 15, thereby driving the rotation of the gear 2 16. When the gear 2 16 rotates, it will drive the threaded rod 18 and the convex gear 19 to rotate. As the convex gear 19 rotates, it will drive the convex gear 2 22 to rotate. The rotation of the Suzi and the table 2 will drive the rotation of another convex gear 19. When the threaded rod 18 is in motion, since the connection between the threaded sleeve 20 and the threaded rod 18 is provided with the same thread as the threaded rod 18, the threaded sleeve 20 will be driven to move downward as the threaded rod 18 rotates, thereby driving the lower pressure plate 21 to move downward and fix the steel belt.

[0025] The motor 2 14 is started to drive the gear 15 to rotate, and the gear 15 drives the gear 2 16 to rotate, and the gear 2 16 drives the threaded rod 18 and the convex gear 19 to rotate, and the convex gear 2 22 drives the other threaded rod 18 to rotate, thereby driving the lower pressure plate 21 to move downward to fix the steel strip. Compared with the traditional device, the device can improve the stability of the steel strip when it is cut by fixing the steel strip, thereby improving the working efficiency of the device and avoiding the deviation of the steel strip when it is cut.

[0026] Among them, a groove 7 is opened on the side of the table top 2, a spring 8 is fixedly installed on the top of the inner side of the groove 7, a lower pressure block 10 is fixedly installed on the bottom of the spring 8, a limiting rod 9 is fixedly installed above the lower pressure block 10, and the top of the limiting rod 9 extends to the top of the table top 2, and a lower pressure wheel 11 is rotatably installed on one side of the lower pressure block 10.

[0027] When the steel belt is placed at the bottom of the lower pressure wheel 11, the lower pressure wheel 11 will move upward with the thickness of the steel belt. When the lower pressure wheel 11 moves upward, it will drive the lower pressure block 10 to move upward. When the lower pressure block 10 moves upward, it will drive the limit rod 9 to move upward, and at the same time the spring 8 will be compressed. However, since the spring 8 has elasticity, it will also apply downward force while being squeezed, driving the lower pressure block 10 to move downward. When the lower pressure block 10 moves downward, it will drive the lower pressure wheel 11 to move downward, thereby applying a downward force to the steel belt. When the steel belt moves, it will drive the lower pressure wheel 11 to rotate.

[0028] A downward force is applied to the lower pressing block 10 through the spring 8, and the lower pressing block 10 will move downward, and the limiting rod 9 will also move downward. As the lower pressing block 10 moves downward, the lower pressing wheel 11 will be driven to move downward, and when the steel belt moves, the lower pressing wheel 11 will be driven to rotate. Compared with the traditional device, the device can flatten the steel belt through the design of the lower pressing wheel 11 without affecting the movement of the steel belt, thereby improving the efficiency of cutting the steel belt and thus improving the working efficiency of the device.

[0029] Among them, a motor bracket 3 is fixedly installed on one side of the table top 2, a motor 4 is fixedly installed on one side of the motor bracket 3, a connecting plate 5 is fixedly installed above the transmission shaft of the motor 4, one end of the connecting plate 5 extends to the interior of the table top 2 and is fixedly installed with a transmission wheel 6, the surface of the transmission wheel 6 extends to the top of the table top 2 and is rotatably connected to the surface of the table top 2.

[0030] First, lay the steel belt on the top of the transmission wheel 6, and start the motor 4 through the controller. When the motor 4 is started, it will drive the connection plate 5 to rotate. When the connection plate 5 rotates, it will drive the transmission wheel 6 to rotate, thereby driving the steel belt to move forward.

[0031] Among them, a bracket 13 is fixedly installed on the top of the U-shaped bracket 12, a motor 2 14 is fixedly installed on the bottom of the bracket 13, a gear 15 is fixedly installed on the transmission shaft of the motor 2 14, and the gear 15 and the gear 2 16 are meshed with each other.

[0032] The second motor 14 is started by the controller. When the second motor 14 is started, the first gear 15 is driven to rotate. Since the first gear 15 and the second gear 16 are meshed with each other, the rotation of the first gear 15 will drive the second gear 16 to rotate.

[0033] A cylinder fixing frame 25 is fixedly installed above the table 2 , a cylinder 26 is fixedly installed above the cylinder fixing frame 25 , the bottom of the cylinder 26 passes through the upper and lower sides of the cylinder fixing frame 25 , and a cutter head 27 is fixedly installed at the bottom of the cylinder 26 .

[0034] The cylinder 26 is started by the controller to drive the cutter head 27 to descend, thereby cutting the steel strip below the cutter head 27 .

[0035] A cutting groove 28 is provided above the table top 2 , and a distance sensor 29 is fixedly installed above the table top 2 .

[0036] The cutting groove 28 can reduce the damage to the table 2 caused by the cutter head 27 when cutting the steel strip. At the same time, the cutting length of the steel strip can be calculated by the distance sensor 29, thereby improving the degree of automation.

[0037] The working principle and use process of this utility model:

[0038] When the staff uses it, the staff starts the device through the controller. After the device is started, the steel belt is laid flat on the top of the device. When the steel belt passes under the distance sensor 29, the distance sensor 29 will start to calculate the length of the steel belt. When the steel belt needs to be cut, the controller starts the motor 2 14 to drive the rotation of the gear 15, thereby driving the rotation of the gear 2 16. When the gear 2 16 rotates, it will drive the threaded rod 18 and the convex gear 19 to rotate. As the convex gear 19 rotates, it will drive the convex gear 2 22 to rotate. The rotation of the Suzi and the table 2 will drive the rotation of another convex gear 19. When the threaded rod 18 is in motion, since the connection between the threaded sleeve 20 and the threaded rod 18 is provided with the same thread as the threaded rod 18, the threaded sleeve 20 will be driven to move downward as the threaded rod 18 rotates, thereby driving the lower pressure plate 21 to move downward and fix the steel belt.

[0039] When the steel belt is placed at the bottom of the lower pressure wheel 11, the lower pressure wheel 11 will move upward with the thickness of the steel belt. When the lower pressure wheel 11 moves upward, it will drive the lower pressure block 10 to move upward. When the lower pressure block 10 moves upward, it will drive the limit rod 9 to move upward, and at the same time the spring 8 will be compressed. However, since the spring 8 has elasticity, it will also apply downward force while being squeezed, driving the lower pressure block 10 to move downward. When the lower pressure block 10 moves downward, it will drive the lower pressure wheel 11 to move downward, thereby applying a downward force to the steel belt. When the steel belt moves, it will drive the lower pressure wheel 11 to rotate.
