Abstract
Description
Technical Field
[0001] This application relates to the field of TPU film processing equipment technology, specifically a TPU film multi-roll connection detection device. Background Technology
[0002] TPU film is a film material made of thermoplastic polyurethane, possessing excellent elasticity, abrasion resistance, chemical resistance, and transparency. It combines the processability of plastics with the high elasticity of rubber, and is widely used in waterproof and breathable membranes, medical devices, clothing fabrics, automotive interiors, and electronic products.
[0003] Currently, in the TPU film production process, it is usually necessary to connect multiple small rolls of TPU film into a large roll to meet the needs of continuous production. However, the small rolls of TPU film need to be changed multiple times in subsequent production processes, which wastes time. In order to solve the above problems, a TPU film multi-roll connection detection device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a TPU film multi-roll connection detection device, which can connect multiple rolls of TPU film into a large TPU film roll, and at the same time perform real-time video inspection of the TPU film during operation to ensure product quality and consistency.
[0005] To achieve the above objectives, this application provides the following technical solution: a TPU film multi-roll connection detection device, comprising a base plate, an unwinding mechanism, a connecting mechanism, a detection mechanism, and a winding module. The unwinding mechanism includes an unwinding frame and an unwinding drum rotatably connected to the inner wall of the unwinding frame. Four unwinding shafts are installed on the inner wall of the unwinding drum. Four second servo motors are fixedly connected to the outer surface of the unwinding drum. The output shaft ends of the four second servo motors are respectively fixedly connected to the rotating shaft ends of the four unwinding shafts. Four sets of first guides are installed on the inner wall of the unwinding drum.
[0006] The connecting mechanism includes two first electric push rods and two second electric push rods fixedly connected to the upper surface of the base plate, as well as a support plate and two connecting plates disposed above the base plate. The output ends of the two first electric push rods are fixedly connected to the bottom surface of the support plate, and the output ends of the two second electric push rods are fixedly connected to the outer surfaces of the two connecting plates respectively. A vortex fan and a heating plate are installed between the two connecting plates.
[0007] The above solution allows for the simultaneous unwinding of four small rolls of TPU film via an unwinding mechanism. A connecting mechanism then sequentially bonds and solidifies these four rolls. An inspection mechanism monitors the TPU film rolls, enabling timely detection and resolution of any quality issues and ensuring high-quality product standards. Finally, a winding module rewinds the film into a large TPU film roll, facilitating subsequent processing, reducing downtime for fabric changes, and enhancing practicality.
[0008] Furthermore, the unwinding mechanism is installed at the front end of the base plate, and the winding module is installed at the end of the base plate.
[0009] The above solution allows multiple rolls of TPU film to be placed on the unwinding mechanism, and then the winding module can wind the multiple rolls of TPU film into a large roll of TPU film, thereby reducing the number of subsequent roll changes and saving time.
[0010] Furthermore, a worm gear is fixedly connected to the shaft end of the unwinding drum, a worm gear meshing with the worm gear is installed on the outer surface of the unwinding frame, and a first servo motor is fixedly connected to the outer surface of the unwinding frame. The output shaft end of the first servo motor is fixedly connected to the shaft end of the worm gear.
[0011] With the above scheme, when the first servo motor is started, the worm gear can drive the worm wheel to rotate. The rotation of the worm wheel can cause the unwinding drum to rotate. When the first roll of TPU film is about to run out, the unwinding drum can be rotated by starting the first servo motor to lead out the second roll of TPU film, which is convenient for subsequent docking with the end of the first roll.
[0012] Furthermore, the position of the first guide corresponds to the position of the unwinding shaft, and the position of the heating plate corresponds to the position of the support plate.
[0013] Using the above method, the TPU film roll mounted on the unwinding shaft can be conveyed through the first guide.
[0014] Furthermore, a heat sink is fixedly connected to the bottom surface of the support plate, and a second guide adapted to the first guide is installed on the upper surface of the base plate.
[0015] The above solution accelerates the heat dissipation of the carrier plate by setting heat sinks, thereby improving the curing efficiency at the joint of the two TPU films. The second guide can smoothly transport the TPU film to the testing mechanism for testing and processing.
[0016] Furthermore, the detection mechanism includes a fixed frame fixedly connected to the upper surface of the base plate, and the inner wall of the fixed frame is equipped with a plurality of guide rollers for guiding.
[0017] The above scheme allows the TPU film after docking to be transported to the winding module for winding via the guide rollers.
[0018] Furthermore, a testing frame is installed above the fixed frame, a high-speed camera module and a light source are installed on the bottom surface of the testing frame, and image processing software is installed on the upper surface of the testing frame. Both the high-speed camera module and the high-speed camera module are electrically connected to the image processing software.
[0019] The above solution allows the high-speed camera module to continuously photograph the TPU film being transported below, and transmit the data to image processing software for image analysis to determine the presence of defects such as bubbles and cracks. The light source provides uniform illumination, thereby optimizing the shooting quality of the high-speed camera module.
[0020] Furthermore, a control component is installed on the outer surface of the fixing frame, and the electrical components inside the unwinding mechanism, connecting mechanism, detection mechanism, and winding module are all electrically connected to the control component.
[0021] The above scheme allows for convenient control of the various electrical components in the device through the established control components, simplifying the operation process.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This TPU film multi-roll connection detection device can simultaneously unwind four small rolls of TPU film using an unwinding mechanism. A connecting mechanism then sequentially bonds and solidifies the four rolls. The detection mechanism inspects the TPU film rolls, enabling timely detection and resolution of various quality issues, ensuring high-quality product standards. Finally, a winding module rewinds the film into a large TPU film roll, facilitating subsequent processing, reducing downtime for fabric changes, and making it more practical.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a TPU film multi-roll connection detection device includes a base plate 1, an unwinding mechanism 2, a connecting mechanism 3, a detection mechanism 4, and a winding module 5. The unwinding mechanism 2 is installed at the front end of the base plate 1. The winding module 5 is installed at the end of the base plate 1. It can place multiple small rolls of TPU film on the unwinding mechanism 2, and then wind the multiple small rolls of TPU film into a large TPU film roll through the winding module 5, thereby reducing the number of subsequent roll changes and saving time. The unwinding mechanism 2 includes an unwinding frame 201 and an unwinding drum 202 rotatably connected to the inner wall of the unwinding frame 201. A worm gear 203 is fixedly connected to the rotating shaft end of the unwinding drum 202. A worm 204 meshing with the worm gear 203 is installed on the outer surface of the unwinding frame 201. A first servo motor 205 is fixedly connected to the outer surface of the unwinding frame 201. The output shaft end of the first servo motor 205 is fixedly connected to the rotating shaft end of the worm 204. When the first servo motor 205 is started, it can drive the worm gear 203 to rotate through the worm 204. The rotation of the worm gear 203 can cause the unwinding drum 202 to rotate. When the first roll of TPU film is about to run out, the unwinding drum 202 on the first servo motor 205 can be started to rotate, leading out the second roll of TPU film, which is convenient for subsequent docking with the end of the first roll. The inner wall of the unwinding drum 202 is equipped with four unwinding shafts 206, and the outer surface of the unwinding drum 202 is fixedly connected to four second servo motors 207. The output shaft ends of the four second servo motors 207 are respectively fixedly connected to the rotating shaft ends of the four unwinding shafts 206. When the second servo motors 207 are started, they can drive the TPU film rolls installed on the unwinding shafts 206 to rotate, thereby enabling them to unwind. The inner wall of the unwinding drum 202 is equipped with four sets of first guides 208. The positions of the first guides 208 correspond to the positions of the unwinding shafts 206, and the TPU film rolls installed on the unwinding shafts 206 can be conveyed through the first guides 208.
[0033] It should be noted that each time the first servo motor 205 is started, the unwinding drum 202 will rotate 90 degrees, which facilitates the subsequent docking of the two TPU film rolls.
[0034] Please see Figure 1 , Figure 2 and Figure 4The connecting mechanism 3 includes two first electric push rods 301 and two second electric push rods 304 fixedly connected to the upper surface of the base plate 1, and a support plate 302 and two connecting plates 305 disposed above the base plate 1. The output ends of the two first electric push rods 301 are fixedly connected to the bottom surface of the support plate 302. When the two first electric push rods 301 are activated, they can drive the support plate 302 to move upward to a designated position. At this time, the bottom surface of the TPU film roll contacts the upper surface of the support plate 302, thus facilitating the subsequent stable docking of the two TPU film rolls. The output ends of the two second electric push rods 304 are fixedly connected to the outer surfaces of the two connecting plates 305 respectively. A vortex fan 30 is installed between the two connecting plates 305. 6. A heating plate 307 is positioned corresponding to the support plate 302. The heating plate 307 heats the TPU film, allowing the two TPU film segments to cure and connect. A vortex fan 306 blows air downwards, accelerating the curing rate. A heat sink 303 is fixedly connected to the bottom surface of the support plate 302. A second guide 308, compatible with the first guide 208, is installed on the upper surface of the base plate 1. The heat sink 303 accelerates the heat dissipation of the support plate 302, thereby improving the curing efficiency at the connection of the two TPU film segments. The second guide 308 smoothly transports the TPU film to the testing mechanism 4 for testing.
[0035] Please see Figure 1 , Figure 2 and Figure 5The inspection mechanism 4 includes a fixed frame 401 fixedly connected to the upper surface of the base plate 1. Multiple guide rollers 402 are installed on the inner wall of the fixed frame 401 for guiding. The guide rollers 402 transport the joined TPU film to the winding module 5 for winding. An inspection frame 403 is installed above the fixed frame 401. A high-speed camera module 404 and a light source 405 are installed on the bottom surface of the inspection frame 403. Image processing software 406 is installed on the upper surface of the inspection frame 403. Both the high-speed camera module 404 and the image processing software 406 are electrically connected. The high-speed camera module 404 can continuously photograph the TPU film being transported below and transmit the data to the image processing software 5. Image processing software 406 performs image analysis to determine the presence of defects such as bubbles and cracks, while the light source 405 provides uniform illumination, thereby optimizing the shooting quality of the high-speed camera module 404. The outer surface of the mounting bracket 401 is equipped with a control component 6. The electrical components inside the unwinding mechanism 2, connecting mechanism 3, detection mechanism 4, and winding module 5 are all electrically connected to the control component 6. The control component 6 includes a PLC controller that coordinates the actions of each subsystem, a touch screen display that shows the operating status and fault information, and a communication interface that supports remote monitoring and data transmission. The control component 6 allows for convenient control of the various electrical components in the device, simplifying the operation process.
[0036] In this embodiment, a TPU film multi-roll connection detection device can simultaneously unwind four small rolls of TPU film using an unwinding mechanism 2. Then, a connecting mechanism 3 sequentially solidifies and connects the four small rolls of TPU film. A detection mechanism 4 then inspects the TPU film rolls, enabling timely detection and handling of various quality issues to ensure high-quality product standards. Finally, a winding module 5 winds the film into a large TPU film roll, facilitating subsequent processing, reducing downtime for fabric changes, and making the device more practical.
[0037] The working principle of the above embodiment is as follows: multiple small TPU film rolls are sequentially mounted on four unwinding shafts 206, and then the films are sequentially led out through the first guide 208. Next, the first servo motor 205 is started to rotate the unwinding drum 202 to the desired position. Figure 3As shown, the first roll of TPU film passes sequentially through the second guide 308 and multiple guide rollers 402, and is then wound up by the winding module 5. During transport in the detection mechanism 4, the TPU film passes through the two guide rollers 402 at the top of the fixed frame 401. At this time, the high-speed camera module 404 continuously captures images of the TPU film being transported below and transmits the image data to the image processing software 406 for image analysis to determine if defects such as bubbles or cracks exist. When the first roll of TPU film is about to run out, the two first electric push rods 301 move the support plate 302 upwards, causing the bottom surface of the support plate 302 to contact the top surface of the first roll of TPU film. Simultaneously, the first servo motor 205 drives the unwinding drum 202 to rotate, causing the unwinding shaft 206 holding the first roll of TPU film to rotate downwards by 90 degrees, positioning the second roll of TPU film at the initial position of the first roll. The unwinding process continues, and finally, the last roll of TPU film... The end stops on the upper surface of the support plate 302. Then, the second servo motor 207, which controls the unwinding of the second roll of TPU film, is started. The second roll of TPU film is then transported to the upper surface of the support plate 302 through the corresponding first guide 208. Then, the two second electric push rods 304 are started to move the two connecting plates 305 downward, which in turn drives the heating plate 307 downward. This clamps the two sections of TPU film between the support plate 302 and the heating plate 307. Then, the heating plate 307 is started to heat the two sections of TPU film, causing the TPU film to partially melt. The melted TPU film penetrates each other under pressure and forms a strong bonding layer. Then, the vortex fan 306 is started to blow air to accelerate the curing process. After the curing is completed, the support plate 302 and the heating plate 307 are returned to their initial state. Then, the winding module 5 is used to continue the winding process. By repeating the above steps, multiple small rolls of TPU film can be wound into a large TPU film roll, which facilitates subsequent processing and reduces downtime for changing fabric.
