[0025] like Figures 1 to 5 As shown, a system for automatically laminating tread film and film includes, along the transmission direction of the tread, a deviation correction unit 1, a film laminating unit 2 and a film laminating unit 4 in sequence. A distance adjustment unit 3 is arranged below the film laminating unit 2. The distance adjustment unit 3 is connected to the deviation correction unit 1 by signal. The distance adjustment unit 3 operates to adjust the width of the film. The deviation correction unit 1, the film laminating unit 2 and the film laminating unit 4 constitute a tread linkage line. The deviation correction unit 1 measures the width of the tread and corrects the transmission direction. The tread after deviation correction is transmitted between the film laminating unit 2 and the distance adjustment unit 3 for automatic film laminating. The tread after laminating the film is transmitted to the film laminating unit 4 for film laminating.

[0026] By setting up a correction unit, a film laminating unit, a distance adjustment unit and a film laminating unit on the tread linkage line, the automatic laminating of the tread buffer film and the film pad can be realized, which can greatly reduce the number of defective products caused by poor laminating; the automatic laminating and cutting of the tread buffer film and the film pad can reduce the number of positions and reduce labor costs.

[0027] In the automatic laminating system for extruding tread buffer film and film of the present embodiment, the correcting unit 1 includes a width measuring component and a correcting component. The correcting component includes a driver 5. The driver 5 is installed on a wire frame 6. A roller frame 7 is also provided on the wire frame 6. The roller frame 7 is connected to the driver 5 in a transmission manner. The driver 5 drives the roller frame 7 to rotate above the wire frame 6 to change the conveying direction of the tread.

[0028] In the automatic bonding system for extruding tread buffer film and film of the present embodiment, the width measuring component includes a width measuring camera 8, and the width measuring camera 8 is connected to the driver 5 by signal. The width measuring camera 8 is arranged above the linkage line, and the tread is at least partially located within the shooting range of the width measuring camera 8 along the conveying path of the linkage line.

[0029] Width measuring components and deviation correcting components are added to the linkage line to achieve stable conveying position of treads of different specifications. The linkage line roller before width measurement is transformed into a deviation correcting roller that can be adjusted in position, namely, the roller frame 7 and the conveying rollers installed on its surface.

[0030] Specifically, the tread is transported by the conveying rollers on the roller frame 7, and passes through each roller in turn and then passes through the width measuring component. An LED light source is correspondingly arranged below the width measuring camera 8. The width measuring camera 8 is preferably a CCD camera. After the conveyed tread blocks the LED light source, the width measuring camera 8 photographs the tread and detects the real-time width value and skewness of the tread, and starts the correction program to perform a mid-position correction action on the tread; the correction program starts the control driver 5 to push the roller frame 7 to move, changes the position of the tread on the roller frame 7, and realizes correction.

[0031] The setting of the deviation correction unit 1 ensures that treads of different sizes can be kept in the center line position of the linkage line during transportation, which can ensure the accuracy of the fit between the buffer film and the tread, and greatly reduce the problem of poor fitting caused by changes in the tread transportation position.

[0032] Preferably, the roller frame 7 and the wire frame 6 are connected and supported by guide wheels and a rotating shaft. The rotating shaft is fixed at the middle width position of the wire frame 6. The rotating shaft is a vertical cylinder with a bearing inside. The guide wheel is fixed on the roller frame 7. Left and right guide wheels are installed in the width direction of the frame for support and movement. The roller frame 7 swings horizontally in a fan shape with the rotating shaft as the fulcrum.

[0033] In the automatic bonding system for extruding tread buffer rubber and film of the present embodiment, the distance adjusting unit 3 includes a tool holder 9, and the tool holder 9 is installed below the calender frame 10. A ball screw 11 with a bidirectional thread on the surface is installed on the tool holder 9, and trimming knives 12 are respectively installed at both ends of the ball screw 11, and one end of the ball screw 11 is fixedly connected to the output end of the servo motor, and the servo motor is connected to the signal of the correction unit 1.

[0034] In the automatic bonding system for extruded tread buffer rubber and film of the present embodiment, the first end of the tool holder 9 is movably connected to the calender frame 10 via an adjusting screw 13, and the second end of the tool holder 9 is slidably connected to a support plate 14, and the support plate 14 is fixedly connected to the calender frame 10. The adjusting screw 13 is rotated to drive the tool holder 9 to slide along the support plate 14 to adjust the overall position of the tool holder 9.

[0035] Specifically, the left side of the tool holder 9 is riveted and fixed to the calender frame 10 by an adjusting screw 13. When the adjusting screw 13 is rotated, the right side of the tool holder 9 can be moved on the support plate 14, and the tool holder 9 can be moved and centered as a whole; the ball screw 11 is at the dividing point in the middle of its length, the left half of the screw is a forward thread, and the right half of the screw is a reverse thread. Two trimming knives 12 are respectively installed on both sides of the ball screw 11. When the ball screw 11 is driven to rotate by a servo motor, the two trimming knives 12 move away from or towards each other to achieve a change in the blade spacing.

[0036] Preferably, small limit blocks are respectively provided at the left and right ends of the upper part of the tool holder 9, and a large limit block is provided in the middle part. The two trimming knives 12 are respectively provided with two inductive proximity switches in opposite directions for identifying the large limit block and the small limit block. When the inductive proximity switch detects the large limit block or the small limit block, the trimming knife servo motor stops rotating; the large limit block and the small limit block are respectively located in the middle and the two end points of the tool holder 9, and their functions are to realize the minimum blade distance and the maximum blade distance of the two trimming knives 12 for safety and anti-collision limit and to find the "zero point" position. Preferably, the two trimming knives 12 are lifted and lowered by a cylinder, and the cylinder rises and pushes the knife body toward the cutting roller on the calender frame 10 to realize the cutting and width setting of the film. The film after cutting and width setting is bonded upward to the bottom of the tread to realize the bonding of the film and the tread.

[0037] Furthermore, the width measuring component, the deflection correcting component, and the distance adjusting unit 3 are connected to the calender host signal, and the distance of the film trimming knife 12 is automatically adjusted according to the measurement data of the width measuring component and the deflection correcting component. The implementation method and steps are as follows:

[0038] (1) Set the "real-time width value" of the calender main machine: the width measuring component measures the tread width in real time during transportation, with a measurement frequency of 5 seconds / time, and the measured width value is displayed on the "real-time width value";

[0039] (2) The calender host sets the "trimming knife distance value": the "trimming knife distance value" is the actual distance between the trimming knives 12, which is calculated by the servo motor data feedback. The trimming knife servo motor is controlled by the calender host program and displayed in real time on the calender host;

[0040] (3) The main program of the calender machine identifies the difference between the "real-time width value" and the "trimming knife distance value". When the difference between the "two values" is greater than 3 mm, the distance of the trimming knife 12 is automatically compensated and adjusted based on the "real-time width value". The servo motor of the trimming knife 12 is controlled to start and drive the ball screw 11 to rotate; that is, the distance of the trimming knife 12 is adjusted accordingly when the "real-time width value" changes, so as to achieve the correspondence between the tread width value and the distance value.

[0041] (4) A regular "zero point" confirmation procedure for the trimming knife 12 blade distance is developed in the main program of the calender. When the actual blade distance is inconsistent with the displayed value of the "trimming knife blade distance value", the trimming knife 12 blade distance "zero point" return correction can be manually started. When the inductive proximity switch detects the large limit block or the small limit block, the trimming knife servo motor stops rotating, and the servo motor feeds back the stop position point to the main program of the calender.

[0042] In the automatic laminating system for extruding tread buffer film and film of the present embodiment, the film laminating unit 2 includes a film detection component, a film pressing component and a film cutting component. The film pressing component and the film cutting component are arranged in sequence along the conveying direction of the linkage line. The film detection component is respectively connected with the film pressing component and the film cutting component by signal. The film detection component detects whether there is a tread on the linkage line, and then controls whether the film pressing component performs a pressing action. The film cutting component cuts the film being conveyed.

[0043] In the automatic laminating system for extruding tread buffer film and film of the present embodiment, the film detection component includes a first front-facing photoelectric switch 15 arranged above the linkage line, the film pressing component includes a film pressing layer sheet 16 arranged above the linkage line, the film pressing layer sheet 16 is arranged between the first front-facing photoelectric switch 15 and the film cutting component, the first front-facing photoelectric switch 15 is signal-connected to the film pressing layer sheet 16, and the film cutting component includes a film cutter 17 rotatably arranged above the linkage line, and the rotation speed of the film cutter 17 is the same as the conveying speed of the linkage line.

[0044] In the tread buffer film and film automatic laminating system of the present embodiment, the film detection component also includes a first rear-facing photoelectric switch 18, and the film laminating component also includes a pressure roller 19, and the pressure roller 19 is arranged between the first rear-facing photoelectric switch 18 and the film cutting component. The first rear-facing photoelectric switch 18 is respectively connected to the pressure roller 19 and the film cutting component signals, and the pressure roller 19 presses the film down while the film cutting component cuts the film being transported.

[0045] Through the above arrangement, when the tread is conveyed to the first front-facing photoelectric switch 15, the film pressing diaphragm 16 falls to press the tread and the film, and when the tread after laminating with the film passes the first rear-facing photoelectric switch 18, the pressure roller 19 falls and presses the film being conveyed, and the film under the tread is automatically torn apart due to the forward force of the tread, thereby realizing the automatic laminating and cutting of the film and the tread.

[0046] Specifically, a first front-facing photoelectric switch 15 is provided to detect the presence or absence of a tread, so as to automatically control the rise and fall of a film pressing layer sheet 16. When the tread is conveyed to the first front-facing photoelectric switch 15, a detection signal is transmitted to a cylinder valve that controls the up and down movement of the film pressing layer sheet 16. The valve opens, and the film pressing layer sheet 16 falls to the top of the tread to perform a pressing action between the tread and the film. When the first front-facing photoelectric switch 15 does not detect a tread, the film pressing layer sheet 16 automatically rises, and the film pressing action is canceled.

[0047] A cutter motor that drives the film cutter 17 to rotate is fixed on the linkage line frame and is located behind the film pressing lye sheet 16 on the linkage line. It is used to drive the film cutter 17 to rotate one circle to cut the film being transported. Preferably, the cutter motor is a variable frequency motor. When cutting the film, the rotation speed is consistent with the linkage line conveying speed. After the film cutter 17 rotates one circle, the cutter motor stops rotating and the film cutter 17 stops at the starting position.

[0048] A first rear-facing photoelectric switch 18 is provided to detect the presence or absence of a tread, so as to automatically control the rise and fall of a pressure roller 19. The pressure roller 19 is driven by a cylinder. When the first rear-facing photoelectric switch 18 detects that there is no tread conveying, the detection signal is transmitted to the cylinder valve of the pressure roller 19 and the cutter motor. The cylinder valve is opened, and the pressure roller 19 falls and presses on the film. The film between the two adjacent conveying rollers is in a concave and stretched state. When the pressure roller 19 falls, the cutter motor is started, driving the film cutter 17 to rotate one circle, and cutting the film being conveyed. When the film cutter 17 cuts the film, the pressure roller 19 is slowly lifted up, and the broken end of the film falls.

[0049] Preferably, a cutting roller is arranged directly below the film cutter 17, and the cutting roller is made of hard rubber. The cutting roller is linked with the production line, and the rotation speed is consistent with the conveying speed of the linkage line. A brush roller is arranged directly below the cutting roller, and the brush roller is composed of a metal shaft and hard brush wires, and is linked with the cutting roller to push and block the cut film, thereby preventing the film from adhering to the cutting roller. When the film is cut by the film cutter 17, the pressure roller 19 has a tensioning effect, so that the cut film can fall below, and the rotation of the brush roller prevents the falling film from adhering to the cutting roller and falling onto the accumulated rubber on the roller of the calender.

[0050] When the film laminating section tread is conveyed, the cut film falls between the upper and lower calendering rollers for mixing. The rotating upper and lower calendering rollers continuously calender the film and convey it to the upper and lower rollers of the calender through the linkage line roller and the cutting roller below the film laminating layer sheet 16 to wait for the tread to be laminated.

[0051] Preferably, the first front-facing photoelectric switch 15 is associated with controlling the start and stop of the extruder: when the first front-facing photoelectric switch 15 does not detect the tread, the extruder stops extruding the rubber; when the tread is delivered to the first front-facing photoelectric switch 15, the extruder starts according to the set program and automatically and quickly adjusts the extruder speed.

[0052] The glue output of the extruder is further associated with the glue output of the calendered film, so that the extruder can automatically supply glue to ensure the continuous and stable calendered buffer film. The implementation method and steps are as follows:

[0053] (1) Confirmation of the amount of rubber extruded at different speeds of the extruder (R: extruder speed, T0: weight of rubber extruded by the extruder per unit time, Th: weight of calendered films of different widths per unit time):

[0054] a. Standardize the width and thickness of the rubber compound used by the extruder so that the size of all different batches of rubber compound used by the extruder is basically the same;

[0055] b. When the width and thickness of the rubber used by the extruder are consistent, measure the weight value T0 of the rubber extruded by the extruder at different speeds R per unit time;

[0056] (2) Confirmation of the amount of rubber used for tread rubber sheets of different widths: The thickness of the current tread cushion rubber sheet is 0.8 mm; weigh or calculate the weight Th of the rubber sheets of different widths rolled in a unit time;

[0057] (3) Correlation between the weight of films of different widths and the speed of the extruder: To ensure the stability of the amount of rubber accumulated on the calender, the amount of rubber extruded by the extruder must be consistent with the amount of calendered film used, that is, T0 = Th;

[0058] (4) Calculate the linear equation Y=AX+B between the extruder speed and TO(Th);

[0059] (5) The calender main machine control system enters the calculation formula (linear equation Y=AX+B) to automatically adjust the extruder speed for films of different widths, so that the calendered film output is consistent with the extruder output, thereby ensuring that the calendered film is continuous and stable.

[0060] In the tread extrusion buffer film and film automatic bonding system of the present embodiment, the film bonding unit 4 includes a film detection component, a film pressing component and a film cutting component, and the film pressing component and the film cutting component are arranged in sequence along the conveying direction of the linkage line. The film detection component is respectively connected with the film pressing component and the film cutting component by signal. The film detection component detects whether there is a tread on the linkage line, and then controls whether the film pressing component performs a pressing action, and the film cutting component cuts the film being conveyed.

[0061] In the extruded tread buffer film and film automatic bonding system of the present embodiment, the film detection component includes an infrared laser 20, and the infrared laser 20 is fixed below the linkage line. The ray position of the infrared laser 20 is aligned with the pad cloth guide frame 21, and the ray and the midline of the correction unit 1 are located in the same vertical plane.

[0062] Specifically, the film detection component includes a second front-facing photoelectric switch, which is provided to detect whether the tread is being conveyed, so as to automatically control the rise and fall of the film pressing layer sheet in the film pressing component; when the tread is conveyed to the second front-facing photoelectric switch, the detection signal is transmitted to the cylinder valve of the film pressing layer sheet, the valve opens, and the film pressing layer sheet falls to the top of the tread to perform the pressing action of the tread and the film; when the second front-facing photoelectric switch does not detect the tread, the film pressing layer sheet automatically rises, and the film pressing action is canceled.

[0063] A film cutter is arranged on the linkage line frame, which is located after the film is pressed into the lyre sheet and is used to cut the film pad. A second rear-facing photoelectric switch is arranged on the linkage line frame to detect whether there is a conveying tread, so as to automatically control the rise and fall of the film cutter. The film cutter is driven by a cylinder. When the second rear-facing photoelectric switch detects that there is no tread conveying, the detection signal is transmitted to the film cutter cylinder valve. The cylinder valve opens and the film cutter quickly falls and presses onto the film pad to cut the film pad between the two conveying rollers. After the cutting action is completed, the cylinder valve closes and the film cutter is lifted up and returns to its original position, and the cut film pad stays on the linkage line roller.

[0064] Preferably, an infrared laser 20 is arranged below the linkage line frame, and the ray position of the infrared laser 20 is the center line of the cloth guide frame 21, which is consistent with the center line of the front correction component. It is used to find the middle point in the width direction of the film cloth when the film cloth is replaced, and plays a centering role to prevent the film cloth from being replaced without accurate position and avoid the cloth from being skewed when fitted.
