Abstract
Description
Technical Field
[0001] This utility model relates to tire production line equipment, specifically a steel cord fabric cutting, width measurement and correction system. Background Technology
[0002] Steel cord fabric refers to tire components with rubber covering steel cords. On a cord calender, the steel cords covered with rubber become steel cord fabric rolls. On a steel cord fabric cutting machine, they are cut at different angles and widths. The cut cord fabric pieces are parallelograms with certain angles and widths.
[0003] To achieve a variety of tire forming specifications, the small-angle steel cord fabric cutting machine is designed with a cutting device. The cord fabric strips connected by the splicing device are cut into cord fabric strips of symmetrical or asymmetrical widths according to different process dimensions. After passing through the edge binding device or the curling device, the strips are rolled up for use by the forming machine.
[0004] After the steel wire cord fabric is longitudinally cut by the slitting cutter, it may be slightly displaced due to the shearing force, which may result in a deviation between the actual cut width and the width required by the process.
[0005] Traditional cutting production lines place the slitting and correction mechanism before cutting, and the width measurement device at the entrance of the next process after cutting. Because the width detection of the fabric after slitting is delayed, it inevitably leads to a long stretch of waste material. Furthermore, the data acquisition devices used for width measurement are relatively expensive, increasing the costs for manufacturing companies. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model proposes a steel wire cord cutting width measurement and correction system that improves the accuracy of steel wire cord width after cutting, increases production efficiency, and reduces material waste.
[0007] A steel cord fabric cutting, width measuring, and deviation correction system capable of solving existing technical problems includes a steel cord fabric conveying device, a steel cord fabric cutting device, and a steel cord fabric width measuring device, wherein:
[0008] 1. The steel wire cord conveying device includes a conveyor belt that transports the steel wire cord belt forward under the drive of a power mechanism.
[0009] 2. The steel cord fabric cutting device is located at the cutting position at the rear of the conveyor belt, and includes a cutting cutter that moves precisely to the left and right under the drive of a power mechanism. The cutting cutter includes an upper and lower counter-rolling disc cutter and a roller-shaped cutter rest. The roller-shaped cutter rest is set close to the bottom of the conveyor belt. The disc cutter cuts the steel cord fabric belt into two steel cord fabric strips of the same or different widths, on the left and right.
[0010] 3. The steel cord fabric width measuring device is located at the detection position at the front of the conveyor belt, including a three-point acquisition and detection mechanism above the left and right steel cord fabric strips. The three-point acquisition and detection mechanism includes three cameras with data acquisition functions: left, middle and right. Each camera is mounted on a linear guide rail via a corresponding slider. The three sliders run synchronously under the drive of the ball screw transmission pair, thereby driving the three cameras to move left and right.
[0011] 4. Three cameras (left, center, and right) collect the width data of the left and right steel wire curtain strips and feed it back to the PLC programmable controller. The PLC programmable controller adjusts the cutting blades left and right according to the width data to ensure that the cutting width of the left and right steel wire curtain strips meets the requirements of the product process parameters.
[0012] Furthermore, several magnets are arranged in front and rear rows below the conveyor belt on the front side of the detection position.
[0013] The beneficial effects of this utility model are:
[0014] 1. In the structure of the steel wire curtain cutting and width measurement and correction system of this utility model, the data of the steel wire curtain strip after being attracted by the magnet is more accurate under the detection of the three-point acquisition and detection mechanism, avoiding the inaccuracy of data caused by the shaking of the steel wire curtain strip.
[0015] 2. In this utility model, the PLC programmable controller uniformly collects and calculates data and issues corresponding instructions. The system runs according to the pre-set program, making it easy to operate.
[0016] 3. In this utility model, the collection point for the width of the steel wire cord strip is very close to the cutting tool, which reduces the waste generated by width fluctuations during long-distance transportation. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.
[0022] The present invention relates to a steel wire cord fabric cutting, width measurement and correction system, which includes a steel wire cord fabric conveying device 1, a steel wire cord fabric cutting device and a steel wire cord fabric width measurement device, all based on a frame 12.
[0023] The steel cord fabric conveying device 1 includes a conveyor belt mounted on a front drive roller and a rear driven roller. A power mechanism I13 drives the front drive roller to move the conveyor belt, which transports the steel cord fabric belt 2 from back to front. The front of the conveyor belt is designated as a detection position, and two rows of magnets 10 arranged left and right are located below the conveyor belt in front of the detection position. The rear of the conveyor belt is designated as a cutting position. Figure 1 , Figure 2 As shown.
[0024] The steel cord fabric cutting device is located at the cutting position of the conveyor belt, and includes a cutting cutter 11 that moves precisely left and right under the servo drive of the power mechanism II 14. The cutting cutter 11 includes upper and lower disc cutters 3 and a roller cutter rest 4. The roller cutter rest 4 (left and right direction) is set close to the bottom of the conveyor belt. The disc cutter 3 (cutter shaft in left and right direction) presses downward against the roller cutter rest 4 and rotates under the drive of the power mechanism III 15. The disc cutter 3 cuts the forward-conveyed steel cord fabric belt 2 into two steel cord fabric strips 5 of the same or different widths, left and right. The left and right steel cord fabric strips 5 are conveyed to the detection position by the conveyor belt. Figure 1 , Figure 2 , Figure 3 As shown.
[0025] The steel cord fabric width measuring device is located at the detection position of the conveyor belt, including a three-point acquisition and detection mechanism positioned above the left and right steel cord fabric strips 5. The three-point acquisition and detection mechanism includes three cameras 6 with data acquisition functions (left, middle, and right). Each camera 6 is mounted on a left-right linear guide rail 7 via a corresponding slider 8. The three sliders 8 move synchronously under the drive of a ball screw drive pair 9, thereby moving the three cameras 6 left and right. The ball screw drive pair 9 is powered by a servo motor 16. The middle camera 6's downward and forward-facing image positions correspond to the inner edges of the left and right steel cord fabric strips 5, namely A2 and B2. The left and right cameras 6's downward and forward-facing image positions correspond to the outer edges of the left and right steel cord fabric strips 5, namely A1 and B1, respectively. Figure 1 , Figure 2 , Figure 3 As shown.
[0026] The width measurement and correction system for steel wire cord fabric cutting according to this utility model has the following steps:
[0027] 1. Input the product process parameters into the PLC programmable controller. The PLC programmable controller controls the power mechanism II 14 and the servo motor 16 respectively to move the cutting tool 11 and the three cameras 6 (left, middle and right) to the set position.
[0028] 2. The power mechanism I13 starts and runs the conveyor belt, which transports the steel wire cord fabric 2 on the conveyor belt forward. The power mechanism III15 starts and drives the disc cutter 3 to rotate.
[0029] 3. At the cutting position, the steel wire cord fabric belt 2 is cut into left and right steel wire cord fabric strips 5 by the disc cutter 3. The conveyor belt continues to run, transporting the left and right steel wire cord fabric strips 5 to the detection position.
[0030] 4. At the detection position, the conveyor belt stops running, and the left and right steel wire curtain strips 5 are stably attracted to the conveyor belt by the magnet 10.
[0031] 5. The three cameras 6, left, center and right, respectively collect the width data (A1A2, B1B2) of the left and right steel wire curtain strips 5. The data information is sent to the PLC programmable controller. The PLC programmable controller calculates the data information according to the set algorithm to obtain the result.
[0032] 6. If the width of the left and right steel wire cord strips 5 meets the product process parameters, the cutting cutter 11 remains in its original position and does not need to be adjusted. The conveyor belt continues to run and transports the left and right steel wire cord strips 5 forward to the next work station.
[0033] 7. If the width of the left and right steel wire curtain strips 5 does not conform to the process parameters, the PLC programmable controller will issue an instruction to precisely adjust the position of the cutting tool 11.
[0034] 8. Repeat steps 2 to 7 to continuously cut, measure, and correct the width until two steel wire cord strips, left and right, that meet the product's process parameters are obtained.
