Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, specifically to a flip-type automatic correction and coating device for producing waterproof membranes. Background Technology

[0002] In the production process of waterproof membrane, in order to achieve the functions of isolation, protection or aesthetics, it is often necessary to cover the surface of the membrane with a thin film after it is formed. This process is called lamination.

[0003] Currently, the lamination process mostly uses a fixed unwinding device, where the film is unfolded and adhered to the surface of the waterproof membrane that is moving at a uniform speed under the unwinding tension. However, in actual production, it has been found that due to factors such as winding deviations or uneven edges of the film master roll itself, tension fluctuations during high-speed unwinding, and minor errors in equipment installation, the film is very prone to lateral "deviation" during lamination. Once this deviation occurs, it can cause the lamination to be skewed, resulting in exposed edges of the product that fail to provide the intended protection, leading to defective or scrap products. In severe cases, the film may completely detach from the membrane, with the asphalt adhesive directly adhering to the production line rollers and other parts, causing production line shutdowns or even equipment damage.

[0004] In existing technologies, the problem of film deviation often relies on on-site observation and manual fine-tuning by operators. The correction response is lagging and the accuracy is difficult to guarantee, which cannot meet the needs of modern high-speed, continuous and automated production. Utility Model Content

[0005] The purpose of this invention is to provide a flip-type automatic correction and coating device for producing waterproof membranes, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flip-type automatic deviation correction and coating device for producing waterproof membrane, comprising a frame and an unwinding frame mounted on the frame. Detection sensors for monitoring membrane deviation are fixedly mounted on both sides of the frame. Support frames are fixedly mounted on both sides of the frame, and a fixing plate is fixedly mounted on each support frame. A bearing seat is slidably mounted on each fixing plate. The two ends of the unwinding frame are rotatably connected to two of the bearing seats in a one-to-one correspondence. A ball screw is rotatably mounted on one of the fixing plates, and a ball nut is driven and engaged on the ball screw. The ball nut is fixedly connected to the corresponding bearing seat.

[0007] Preferably, each of the fixed plates is fixedly provided with a guide rod, each of the bearing seats is fixedly provided with a movable plate at the bottom, each of the movable plates is fixedly provided with a guide block at the bottom, and each guide block is slidably connected to each guide rod in a corresponding manner.

[0008] Preferably, upright plates are fixedly installed on both sides of the frame, a lower cutter is fixedly installed between the two upright plates, and an upper cutter is slidably installed between the two upright plates.

[0009] Preferably, one of the fixing plates has grooves on both sides, and a sliding plate is slidably disposed in each groove.

[0010] Preferably, the upper cutter is fixedly provided with multiple drive plates, each drive plate is provided with a V-shaped groove, and each V-shaped groove is provided with a slider.

[0011] Preferably, a pusher frame is slidably arranged between the two upright plates, and both ends of each slider are fixedly connected to the pusher frame. A U-shaped frame is fixedly arranged at one end of the pusher frame near the ball screw, and both ends of the U-shaped frame are fixedly connected to the two slide plates one by one.

[0012] Preferably, a spring is fixedly installed between each of the aforementioned sliding plates and the fixed plate.

[0013] In the above technical solution, this utility model provides a flip-type automatic correction and laminating device for producing waterproof membrane rolls, which has the following beneficial effects: This device monitors the film position in real time through detection sensors and can respond quickly when deviation is detected, driving the ball screw to rotate. The ball nut moves accordingly, causing displacement of the unwinding frame, thereby quickly and accurately compensating for deviations and meeting the needs of modern high-speed, continuous, and automated production. When the film deviation is too large, causing the ball nut to be unable to correct the deviation within its normal stroke, it will push the slide plate to move, thereby controlling the action of the push frame, causing the upper cutter to move downwards and cut the film, thus avoiding greater losses.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-5An automatic deviation correction and coating device for producing waterproof membrane rolls is disclosed. The proposed technical solution includes a frame 1 and an unwinding frame 8 mounted on the frame 1. Detection sensors 10 for monitoring membrane deviation are fixedly mounted on both sides of the frame 1. Support frames 2 are fixedly mounted on both sides of the frame 1, and fixed plates 3 are fixedly mounted on each support frame 2. Bearing seats 7 are slidably mounted on each fixed plate 3. The unwinding frame 8 is rotatably connected at both ends to the two bearing seats 7. A roller is rotatably mounted on one of the fixed plates 3. Ball screw 11, with ball nut 12 for transmission, and ball nut 12 fixedly connected to corresponding bearing seat 7; support frame 2 is fixedly installed on both sides of frame 1, bearing seat 7 is used to support unwinding frame 8, unwinding frame 8 is provided with two unwinding rollers 9 for unwinding film, unwinding frame 8 can be easily replaced when flipping, this is prior art and will not be described in detail, side plates 14 are fixedly installed on both sides of corresponding fixing plate 3, ball screw 11 is rotatably installed between the two side plates 14, detection sensor 1 The sensor 10 is fixedly installed on the side of the film travel path by a bracket, with its probe facing the preset edge position of the film for real-time monitoring. The sensor 10 is one of the following: ultrasonic sensor, photoelectric sensor, and CCD vision sensor (such as SICK WTB series, UC series; Banner T30UX series, etc.). The model and corresponding installation and usage methods are well known to those skilled in the art and will not be described in detail. A controller is also provided on the side wall of the frame 1. The controller is a PLC controller, a type of single-chip microcomputer. The sensor 10 is electrically connected to the controller. The ball screw 11 is parallel to the unwinding roller 9. When the sensor 10 detects a deviation in the edge position of the film, it transmits a signal to the controller. The controller drives the ball screw 11 to rotate, causing the ball nut 12 to move along the ball screw 11, which drives the corresponding bearing seat 7 and the entire unwinding frame 8 to move in the opposite direction to the deviation to compensate for the deviation and return the film to the correct position. When the sensor 10 does not detect the deviation and it is eliminated, the controller controls the ball screw 11 to stop.

[0025] Specifically, a servo motor 13 is fixedly mounted on one of the fixed plates 3. The output end of the servo motor 13 is fixedly connected to the ball screw 11. The servo motor 13 is electrically connected to the controller. When the controller receives a signal of film deviation, it will control the servo motor 13 to drive the ball screw 11 to rotate accordingly.

[0026] Specifically, each fixed plate 3 is fixedly provided with a guide rod 4, each bearing seat 7 is fixedly provided with a movable plate 6 at its bottom, and each movable plate 6 is fixedly provided with a guide block 5 at its bottom. Each guide block 5 is slidably connected to each guide rod 4 in a one-to-one correspondence. The length of the guide rod 4 is the same as the length of the ball screw 11. The stability of the unwinding frame 8 can be increased by the guide rod 4 and the guide block 5.

[0027] Specifically, upright plates 25 are fixedly installed on both sides of the frame 1, and a lower cutter 19 is fixedly installed between the two upright plates 25. An upper cutter 20 is also slidably installed between the two upright plates 25. The upper cutter 20 and the lower cutter 19 are located on the side of the frame 1 closer to the detection sensor 10. The film passes between the upper cutter 20 and the lower cutter 19 and then passes through the detection sensor 10. The correction stroke of the automatic correction mechanism is limited. When the film deviation exceeds the correction limit, or the correction amplitude is too large, indicating that the unwinding or transmission is extremely unstable, the film needs to be cut immediately to ensure safety. At this time, the ball nut 12 will drive the upper cutter 20 to move down and cooperate with the lower cutter 19 to complete the cutting.

[0028] Specifically, one of the fixed plates 3 has grooves 17 on both sides, and a sliding plate 15 is slidably installed in each groove 17. The distance between the two grooves 17 is within the normal correction range. Under normal conditions, the ball nut 12 moves between the two grooves 17. When the movement of the ball nut 12 exceeds the limit of the groove 17, it will push the sliding plate 15. When the sliding plate 15 moves, it will drive the upper cutter 20 to move down to cut the film and prevent greater losses.

[0029] Specifically, multiple drive plates 21 are fixedly installed on the upper cutter 20. Each drive plate 21 has a V-groove 22, and a slider 23 is slidably installed in each V-groove 22. Under normal conditions, each slider 23 is located at the bottom of the middle of the V-groove 22. At this time, the film is not deviated or is within the correction range. When the film deviates beyond the correction range, the controller will cause the ball screw 11 to rotate continuously, thereby causing the ball nut 12 to go beyond the range between the two slides 17 and push the corresponding slide plate 15 to move. When the slide plate 15 moves, it pushes each slider 23 to move, thereby causing the slider 23 to move out from the bottom of the V-groove 22. At this time, no matter which direction the slider 23 moves, it will drive the upper cutter 20 to move down and cut the film.

[0030] Specifically, a pusher frame 24 is slidably arranged between the two upright plates 25. Both ends of each slider 23 are fixedly connected to the pusher frame 24. A U-shaped frame 18 is fixedly arranged at one end of the pusher frame 24 near the ball screw 11. Both ends of the U-shaped frame 18 are fixedly connected to the two slide plates 15 one by one. The upper cutter 20 moves up and down along the upright plate 25. During the movement of the pusher frame 24, it will drive each slider 23 to move. The pusher frame 24 is fixedly connected to the two slide plates 15 through the U-shaped frame 18. The movement of any slide plate 15 will drive the pusher frame 24 to move. Therefore, no matter which direction the film deviates too much, the upper cutter 20 will move down.

[0031] Specifically, each slide plate 15 is fixedly installed between itself and the fixed plate 3. The spring 16 is installed between the slide plate 15 and the corresponding side plate 14. Two guide rollers 26 are fixedly installed on the frame 1. The film passes through the two guide rollers 26. When the film passes through the upper cutter 20 and the lower cutter 19, it will not come into contact with the upper cutter 20 or the lower cutter 19, thus avoiding damage to the film. Then the film passes by the detection sensor 10. In the initial state, the corresponding spring 16 keeps the slide plate 15 at the end of the slide groove 17 away from the side plate 14. At this time, the upper cutter 20 and the lower cutter 19 are separated. If the deviation is too large, the ball nut 12 will not complete the correction when it comes into contact with the slide plate 15. Then the ball nut 12 will continue to move in the corresponding direction, thereby driving the corresponding slide plate 15 to move.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
