Description

Technical Field

[0001] This utility model relates to the technical field of tire cord cutting, and in particular to a tire cord cutting device. Background Technology

[0002] Tire cord fabric forms the skeleton of tires and other rubber products, serving functions such as bearing internal pressure and maintaining shape and dimensional stability. Commonly used tire cord fabrics include cotton cord fabric, nylon cord fabric, carbon fiber cord fabric, etc. In the tire manufacturing process, the cord fabric needs to be cut to a specific length first. For example, a tire cord fabric cutting device proposed in prior art announcement number CN212560882U includes a worktable, a column mounted on the upper surface of the worktable, a motor mounted on the column, a rotating shaft rotatably mounted on the column, the rotating shaft being coaxially connected to the output shaft of the motor, a cutting blade mounted on the rotating shaft, a limit rod welded to the cutting blade, a guide tube horizontally mounted on the top of the column, a threaded rod horizontally inserted into the guide tube, adjusting nuts screwed to both ends of the threaded rod, a connecting rod welded to one end of the threaded rod, a nut welded to the end of the connecting rod, an adjusting stud vertically screwed to the nut, the adjusting stud abutting against the limit rod, and a sliding rod connected to the other end of the threaded rod through a positioning structure. However, the fabric to be cut has no constraints. When the cutting blade cuts the fabric, the shearing force provided by the cutting blade will pull the fabric along the length of the fabric, causing the fabric to easily shift and bend, resulting in low cutting accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an aviation tire cord fabric layer cutting device that can avoid displacement and bending deformation of the cord fabric during cutting by the cutting knife and improve cutting accuracy.

[0004] This utility model discloses an aircraft tire cord fabric cutting device, comprising a base, two sets of upright plates, two side plates, a feeding component, a conveying component, and a cutting component. Upright plates are installed on the left and right sides of the top of the base, and a side plate is installed between the two upright plates. The feeding component is installed on the left upright plate, the conveying component is installed between the front and rear upright plates and the side plate, and the cutting component is installed between the two side plates. The feeding component releases the cord fabric, and the conveying component presses and conveys the cord fabric to reduce cord fabric deformation, ensuring that the cord fabric to be cut is flat and the cut is neat. During cutting, the cutting component can prevent the cord fabric from shifting and bending as it is cut by the cutting blade, thereby improving cutting accuracy.

[0005] Preferably, the conveying component includes a conveying roller, a first conveying motor, two push sliders, a pressure roller, and two first springs. The conveying roller is rotatably mounted between two vertical plates on the left side. The input end of the conveying roller is connected to the output end of the first conveying motor. A push groove is provided at the upper end of the vertical plate, and a support slide rod is provided in the push groove. The push slider is slidably mounted on the outer wall of the push groove and the support slide rod. A pressure roller is rotatably mounted between the front and rear push sliders. The first spring is sleeved on the outside of the support slide rod.

When the first conveying motor is started, it drives the conveying roller to rotate and convey the curtain fabric. At the same time, the first spring pushes the push slider to slide on the push groove and the support slide rod, so that the pressure roller presses against the conveying roller to prevent the curtain fabric from slipping and ensure conveying efficiency.

[0006] Preferably, it further includes a second conveying roller, two sliding rods, two pressing sliders, a second pressing roller, two second springs, a smooth plate, an exit plate, an exit plate, and a second conveying motor. The second conveying roller is rotatably mounted between the middle of the two side plates. The input end of the second conveying roller is connected to the output end of the second conveying motor. A pressing groove is provided on the side plate. The sliding rod is installed in the pressing groove.

The guide plate is installed at an incline between the two side plates on the right side of the second conveying roller. The guide plate is installed on the outer wall of the two vertical plates on the right side. The curtain fabric conveyed between the conveying roller and the pressure roller moves on the upper surface of the smooth plate, and then passes through the second conveying roller and the second pressure roller. The second spring pushes the pressing slider to slide on the sliding rod to ensure the pressing force between the second pressure roller and the second conveying roller, to prevent the curtain fabric from slipping, to prevent the curtain fabric from shifting and deforming, to flatten the curtain fabric, and to ensure flatness. The smooth plate and the guide plate are located on the same plane, and the curtain fabric is conveyed to the right and sent out through the guide plate.

[0007] Preferably, the cutting component includes a fixed plate, a cutting cylinder, a movable plate, two sets of clamping rods, two positioning plates, two sets of third springs, and two connecting plates.

Support bearings are rotatably installed at the front and rear ends of the release roller, and the support bearings are located in the placement grooves. The release roller is supported by the support plates, and the release roller rotates on the support bearings to release and feed the curtain fabric.

[0009] Preferably, the device also includes two limiting slide rods, two guide sliders, a rangefinder, and a controller. Guide grooves are provided on the side plates corresponding to the moving plate. The limiting slide rods are installed within the guide grooves, and the guide sliders are slidably installed on the outer walls of the guide grooves and limiting slide rods.
