Description

Technical Field

[0001] This utility model relates to the technical field of tire cutting, specifically to a non-stop cutting device for an aircraft tire extrusion production line. Background Technology

[0002] The tire tread and sidewall shoulder pad rubber of aircraft tires, also known as tire extrusion production line, is often produced in long strips, and is a continuous long section. In order to facilitate transportation and storage, it needs to be cut and rolled up.

[0003] For example, Chinese utility model patent CN119681973A discloses a tire half-part cutting device, including a conveying mechanism, a cutting mechanism, and a driving mechanism. The conveying mechanism is used to convey the entire tire half-part. The cutting mechanism is arranged above the conveying mechanism and can reciprocate laterally along the conveying mechanism. During the reciprocating movement of the cutting mechanism along the conveying mechanism, it cuts sections of tire half-part from the entire tire half-part. The driving mechanism is used to drive the cutting mechanism to reciprocate laterally along the conveying mechanism within a preset area. By using the driving mechanism, the cutting mechanism is restricted to linear reciprocating motion within a limited area, effectively reducing the amplitude of the linear reciprocating motion of the cutting mechanism, shortening the ineffective movement distance, thereby reducing wasted time and improving production cycle time.

[0004] However, in actual use, it has been found that the existing devices cannot adjust the cutting size for different tires because the required cutting dimensions are not constant, thus reducing the practicality of the devices. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a non-stop cutting device for an aviation tire extrusion production line, which facilitates limiting operations for tires of different sizes that need to be cut, improves the efficiency and cutting effect of the device for tire cutting, and enhances its practicality.

[0006] This utility model discloses a non-stop cutting device for an aircraft tire extrusion production line. The top of two steel beams is fixedly mounted with a support plate by multiple brackets. The top of the support plate is provided with a limiting mechanism and a cutting mechanism. The limiting mechanism includes a top plate, and the bottom end of the top plate is fixedly connected to the outer side wall of the two steel beams by two vertical plates respectively.

[0007] The cutting mechanism includes a cutting machine, which is slidably connected to the bottom end of the top plate via a sliding mechanism. An oblique hole is obliquely opened in the middle area of ​​the top of the support plate. Two fixed rods are symmetrically fixedly installed on the top of the support plate. A groove is opened on the opposite side of each fixed rod, and a slider is slidably installed on each groove. The two sliders are fixedly connected by a limiting plate. A first screw is horizontally rotatably installed inside one of the grooves, and the first screw is screwed onto the slider slidably installed inside the groove. This non-stop cutting device for the aircraft tire extrusion production line rotates the rotating shaft simultaneously with the rotating roller, thereby achieving the desired rotational operation. The rotating rollers convey the tires to the top of the pallet via a support frame. Simultaneously, rotating the first screw drives a slider to slide along a groove. The slider's movement also moves a limiting plate at the top of the pallet, where its outer wall contacts the tire, thus limiting its position. This sliding mechanism facilitates the cutting machine's movement at the bottom of the top plate, allowing for tire cutting. The device's ability to limit tires of different sizes improves cutting efficiency and effectiveness, enhancing its practicality.

[0008] Preferably, the sliding mechanism includes a movable block, which is fixedly installed on the top of the cutting machine. A limiting post is fixedly installed between the two upright plates, and a second screw is rotatably installed between the two upright plates. The limiting post is slidably connected to the movable block, and the second screw is screwed onto the movable block. A first motor is fixedly installed on the outer wall of one of the upright plates, and the first motor is fixedly connected to one end of the second screw. Power is output through one end of the first motor, thereby synchronously driving the second screw to rotate. Since the second screw and the movable block are screwed together, the movable block drives the cutting machine to move laterally under the limitation of the limiting post while the second screw rotates, thereby cutting the tire material.

[0009] Preferably, a second screw is screwed onto the top of the top plate, and a clamping plate is rotatably installed at the bottom of the second screw. Two stop bars are symmetrically and longitudinally fixedly installed on the top of the clamping plate. Each stop bar is slidably connected to the top plate. By rotating the second screw, the clamping plate is simultaneously driven to move under the limitation of the two stop bars. The top of the second screw and the support plate contact the tire, thereby clamping and fixing the tire.

[0010] Preferably, a conveyor belt is tensioned and fitted between two rotating rollers located at the bottom end of the pallet, and a drive wheel is fixedly installed at one end of each of the three rotating shafts. A drive belt is tensioned and fitted between each adjacent drive wheel. Through the transmission of the drive wheel and the drive belt, several rotating shafts and rotating rollers are synchronously driven to rotate, which in turn drives the conveyor belt to rotate synchronously. The cut tires are transported by the rotating conveyor belt.

[0011] Preferably, a scale is fixedly installed at the top of each of the fixed rods, and one end of each scale is parallel to the cutting position of the cutting machine. By installing the scale, it is convenient to slide the limiting plate when performing limiting operations on different tires.

[0012] Preferably, the top of the tray is provided with a connecting groove, which facilitates the provision of working space for the bottom area of ​​the blade during the cutting process.

[0013] Preferably, a second motor is fixedly installed on the outer wall of one of the steel beams. The second motor is fixedly connected to one end of a rotating shaft with a transmission wheel. The second motor outputs power to synchronously drive the rotating shaft and the rotating roller to rotate.

[0014] Preferably, a plurality of limiting rollers are rotatably installed between the two opposing brackets, which facilitates the conveying of tires.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This non-stop cutting device for the aircraft tire extrusion production line drives the rotating roller to rotate simultaneously with the rotating shaft, thereby conveying the tire through the rotating roller. The tire is then conveyed to the top of the pallet by the bracket. Simultaneously, the first screw drives the slider to slide on the slide groove. As the slider moves, the limiting plate moves simultaneously at the top of the pallet. The outer wall of the limiting plate contacts the tire, thereby limiting the tire. With the cooperation of the sliding mechanism, the cutting machine can slide at the bottom of the top plate to cut the tire. This allows for limiting the tire for different sizes, improving the efficiency and effect of tire cutting and enhancing practicality. Attached Figure Description
