Description

Technical Field

[0001] This utility model relates to the field of medical packaging film composite devices, and in particular to medical packaging film composite devices with automatic correction and tension control functions. Background Technology

[0002] In the field of medical packaging, the production of composite films is a crucial step in ensuring packaging quality. Medical packaging films are typically composed of multiple layers of different materials to meet performance requirements such as waterproofing, antibacterial properties, and breathability. This equipment is a key automated device in medical packaging production, primarily used to bond various functional substrates together through processes such as adhesive coating, heating, and pressurization to form a medical packaging film with barrier, sealing, and sterilization resistance properties. These films are widely used in medical device and pharmaceutical packaging, effectively isolating external microorganisms, moisture, and oxygen, ensuring the safety and stability of medical products during storage, transportation, and sterilization. Their performance directly determines the product quality and safety of the medical packaging film.

[0003] The device consists of five main components: a substrate unwinding system equipped with multiple unwinding rollers, with high-end models also featuring pretreatment components; an adhesive coating and laminating system including an adhesive coating roller, a doctor blade, a laminating roller, and a heating module, enabling adhesive coating and bonding; an automatic deviation correction system equipped with photoelectric sensors, actuators, and a control system, capable of adjusting the substrate position; a tension control system consisting of sensors, clutches, and controllers, which stabilizes tension and prevents film deformation; and a winding and cutting system with winding rollers, a tension adjustment unit, and a fixed-length cutting component, capable of completing winding and cutting.

[0004] In existing technologies, the accuracy of automatic alignment is greatly affected by the characteristics of the substrate, making it prone to misidentification and frequent adjustments, which affects the accuracy of the composite and may cause interlayer misalignment. Tension control response is lagging, and adjustments are not timely when tension changes, which can easily lead to composite film quality problems and film deformation and wrinkles. The equipment has poor compatibility and high maintenance costs. Therefore, we propose a medical packaging film composite device with automatic alignment and tension control functions. Utility Model Content

[0005] The purpose of this invention is to provide a medical packaging film laminating device with automatic correction and tension control functions. The unstable tension of the film material leads to stretching deformation or wrinkles, affecting the lamination quality. The lack of automatic correction function makes it difficult to quickly correct the positional deviation of the film material, resulting in low lamination accuracy and high scrap rate. This invention aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medical packaging film composite device with automatic correction and tension control functions, including a base, a plurality of support seats on the top of the base, a conveyor roller rotatably connected between the plurality of support seats, a connecting line on the outside of the support seats, and a controller on the top of the base. The advantages of this design are: the base and support seats provide a stable installation foundation, the conveyor rollers enable smooth conveying of the film material, and the connecting line provides a path for power transmission between the controller and various components, ensuring the stability of the device's basic operation and the synergy of its components.

[0007] In some embodiments, sensors are provided on the top of each of the plurality of support seats, and two fixed seats are provided on the top of the base. A guide roller is rotatably connected between the two fixed seats, and a winding motor is provided on the outside of the fixed seats. The advantage of this design is that the sensors can monitor the film material status in real time, the fixed seats stably support the guide rollers, and the winding motor drives the guide rollers to achieve the winding of the finished film, thereby improving the accuracy of film material detection and winding.

[0008] In some embodiments, the base is provided with two fixed brackets on the side near the controller, and a roller is rotatably connected between the two fixed brackets. The advantage of this design is that the fixed brackets provide stable support for the roller, and the roller can cooperate to guide the membrane material, providing reliable support for the membrane material conveying path and ensuring smooth membrane material flow.

[0009] In some embodiments, the output end of the winding motor is located inside the guide roller, and the connecting line is located outside the controller. The advantages of this design are: the winding motor drives the guide roller, reducing the space occupied by the external transmission structure; the connecting line is located outside the controller, facilitating maintenance and signal transmission between components, and improving the compactness and ease of maintenance of the device.

[0010] In some embodiments, an unwinding motor is provided on the outside of the fixed bracket, and the output end of the unwinding motor is located inside the roller. The advantage of this design is that the unwinding motor drives the roller to control the unwinding speed of the film, reduces transmission loss, adapts to tension adjustment requirements, and ensures the stability of the unwinding process.

[0011] In some embodiments, a connecting block is provided on the outside of the support base, and a slide rail is provided on the outside of the connecting block. Two sliders are slidably connected to the outside of the slide rail. The advantage of this design is that the connecting block provides a stable installation base for the slide rail, and the sliders can slide along the slide rail and drive other components to move, providing an adjustable base for the lateral position correction of the membrane material and ensuring the stability of the correction action.

[0012] In some embodiments, a movable block is connected to the top of the slider, and a movable rod is rotatably connected to the top of the movable block. The advantage of this design is that the slider drives the movable rod through the movable block, and the rotation of the movable rod can finely adjust the film material conveying angle in real time, effectively compensating for lateral deviations and improving the correction accuracy and film material feeding stability.

[0013] In some embodiments, an electric push rod is provided on the top of the connecting block, and the output end of the electric push rod is located outside the movable block. The advantage of this design is that the electric push rod can drive the movable block to slide the slider, realize the automatic correction adjustment of the lateral position of the membrane material, ensure rapid correction response, and improve correction efficiency and stability.

[0014] This invention has at least the following beneficial effects: 1. The base provides overall support, and the rollers supported by the fixed bracket hold the film roll to be laminated. The unwinding motor drives the rollers to unwind, and the film material is conveyed by the conveyor rollers supported by the support base. The sensor on the top of the support base monitors the film tension and position deviation and transmits the data to the controller through the connecting line. The controller sends commands to the unwinding motor and the winding motor to adjust the speed of the rollers and guide rollers, thereby solving the problem of unstable film tension.

[0015] 2. When the sensor detects lateral deviation of the membrane material, the controller drives the electric push rod to push the movable block, causing the movable block to move the slider along the slide rail. At the same time, the movable rod at the top of the movable block adjusts its angle to assist in pushing the membrane material back to the path, thus solving the problem of easy deviation during membrane material transportation.

The connecting line 8 is used to realize signal transmission between the sensor 9 of the support seat 3 and the controller 7, ensuring the coordinated operation between components.

[0020] A controller 7 is installed on the top of the base 1. The controller 7 receives signals from various sensors and sends commands to the motor actuators to achieve automatic correction and tension control. Sensors 9 are installed on the top of multiple support seats 3. The sensors 9 monitor the tension changes and lateral position deviation of the film material in real time and transmit the monitoring data to the controller 7 to provide a basis for regulation. Two fixed seats 2 are installed on the top of the base 1. The fixed seats 2 are used to fix and support the guide roller 16 to ensure that the guide roller 16 does not shift during operation. The guide roller 16 is rotatably connected between the two fixed seats 2. The guide roller 16 is used to guide the finished composite film material to the winding structure to ensure the flatness of the film material during winding. A winding motor 4 is installed outside the fixed seats 2. The winding motor 4 provides power for the rotation of the guide roller 16. The winding speed of the finished film is controlled by adjusting the speed to stabilize the winding process in accordance with the tension control requirements.

[0021] Two fixed brackets 18 are provided on the side of the base 1 near the controller 7.
