Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film research and development, in particular to a detection device for the research and development of a high-barrier biaxially stretched coextruded film. Background Technique
[0002] High-barrier plastic packaging materials in the Chinese market have become one of the important development directions of plastic packaging materials. Now, a variety of new high-barrier materials with excellent performance have been developed, and these new materials will be widely used in the packaging of food, medicine, etc. A high-barrier film refers to a packaging film that protects the packaged contents and prevents the infiltration of pollutants, oxygen, water vapor, liquids, odors and other small-molecule substances, and at the same time can also prevent the packaged contents from leaking out. Therefore, the uniformity of the film is also very important for its performance, and this performance needs to be detected before leaving the factory.
[0003] When conducting detection, to ensure the accuracy of the detection, it is necessary to keep the film in a taut state. Therefore, a pressure roller is often used to achieve the tensioning purpose. However, the moving range of the pressure roller is limited after all. When the pressure roller moves to the end, the tensioning purpose cannot be achieved, and there is room for improvement. Content of the Utility Model
[0004] The purpose of the utility model is to provide a detection device for the research and development of a high-barrier biaxially stretched coextruded film to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A detection device for the research and development of a high-barrier biaxially stretched coextruded film, including a bottom plate, characterized in that: a trigger assembly is installed on the top of the bottom plate, and the trigger assembly includes a mounting frame I fixedly connected to one side of the outer wall of the top of the bottom plate. A plurality of sliding rods are slidably inserted into the outer wall of the top of the mounting frame I. One end of the bottom of the plurality of sliding rods is fixedly connected to the same moving frame. A pressure roller is rotatably connected inside the moving frame. A plurality of springs are fixedly connected between the moving frame and the mounting frame I, and the plurality of springs are respectively located outside the plurality of sliding rods. Two trigger buttons are fixedly connected to the outer wall of one side of the moving frame, and one end of the moving frame is located in the middle of the two trigger buttons.
[0006] As a further preferred of this technical solution, both of the two trigger buttons are electrically connected to the driving device of the take-up roller through wires, and the driving device is set as a speed-regulating motor.
[0007] As a further preferred of this technical solution, a limiting roller is fixedly installed on both sides of the outer wall of the top of the bottom plate, and two receiving rollers are fixedly installed at the middle position of the outer wall of the top of the bottom plate. The same film body is sleeved on the two limiting rollers and the two receiving rollers, and the pressure roller can squeeze the upper surface of the film body.
[0008] Enable the driven film to always maintain a taut state, preventing the pressure roller from losing its function of tensioning the film when it moves to the end, ensuring that the detection effect can always be maintained. If the film body becomes slack during transmission, the pressure exerted by the film body on the pressure roller will also decrease, and the compressed spring will gradually return to its original length. The moving frame and the pressure roller will be driven to squeeze the film body, ensuring that the film body can still maintain a taut state during this period until the moving frame squeezes the trigger button near the outside. This trigger button will then control the speed-regulating motor that drives the take-up roller outside to rotate faster. When the film supply is insufficient, it will gradually become taut again, and the pressure it exerts on the pressure roller will also increase accordingly, and the spring will be compressed and shortened again. When the moving frame squeezes the inner trigger button, the external regulating motor will also return to its original speed. Thus, the film body can always be kept in a taut state.
[0009] As a further preference of this technical solution, a detection component is installed on the top of the bottom plate, and the detection component is located at the middle position between the two receiving rollers.
[0010] As a further preference of this technical solution, the detection component includes a second mounting frame fixedly connected to the outside of the bottom plate. The same bidirectional lead screw is rotatably connected to the inner walls of the top and bottom of the second mounting frame. One ultrasonic detector is threadedly connected to each end of the bidirectional lead screw. One same limiting rod is slidably inserted into one side of the two ultrasonic detectors. The limiting rod is fixedly connected between the inner walls of the top and bottom of the second mounting frame. A motor is fixedly installed on the outer wall of the top of the second mounting frame, and the motor shaft is coaxially fixed to one end of the bidirectional lead screw.
[0011] As a further preference of this technical solution, an ultrasonic generator is fixedly installed on the outer wall of the top of the second mounting frame, and the two ultrasonic detectors are electrically connected to the ultrasonic generator through wires.
[0012] First, adjust the relative positions of the two ultrasonic generators according to the specifications of the film body. By starting the motor to drive the bidirectional lead screw to rotate, the two ultrasonic detectors will approach or move away from each other under the restriction of the limiting rod and the drive of the bidirectional lead screw, thus ensuring that the detected pattern is clearer, which is beneficial to increasing the adaptability of the device, and the cooperation of the two ultrasonic detectors can ensure that the detection result is more accurate.
[0013] The utility model provides a detection device for the research and development of a high-barrier biaxially stretched coextruded film, which has the following beneficial effects:
[0014] (1) By providing a trigger assembly in the present utility model, the driven film can always be kept in a taut state, preventing the situation where the pressing roller loses its function of tensioning the film when it moves to the end, ensuring that the detection effect can always be maintained. If the film body becomes slack during transmission, the pressure exerted by the film body on the pressing roller will also decrease, and the compressed spring will gradually resume its length. The moving frame and the pressing roller will be driven to squeeze the film body, ensuring that the film body can still be kept in a taut state during this period until the moving frame squeezes the trigger button near the outside. This trigger button will control the speed-regulating motor that drives the winding roller outside to rotate faster, and the insufficient film supply will gradually become taut again, and the pressure it exerts on the pressing roller will also increase accordingly, and the spring will be compressed and shortened again. When the moving frame squeezes the inner trigger button, the external regulating motor will also resume its original speed. Thus, the film body can always be kept in a taut state.
[0015] (2) By providing a detection assembly in the present utility model, first adjust the relative positions of the two ultrasonic generators according to the specifications of the film body. By starting the motor to drive the bidirectional lead screw to rotate, the two ultrasonic detectors will approach or move away from each other under the restriction of the limit rod and the drive of the bidirectional lead screw, thus ensuring that the detected pattern is clearer, which is beneficial to increasing the adaptability of the device. And the two ultrasonic detectors cooperate with each other to ensure that the detection result is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.
[0022] The technical solution provided by the present utility model is as follows: As Figure 1 and Figure 3 shown, in this embodiment, a detection device for the research and development of a high-barrier biaxially stretched coextruded film includes a bottom plate 1, and is characterized in that: a trigger assembly 5 is installed on the top of the bottom plate 1. The trigger assembly 5 includes a first mounting frame 501 fixedly connected to one side of the outer wall of the top of the bottom plate 1. A plurality of sliding rods 502 are slidably inserted into the outer wall of the top of the first mounting frame 501. One end of the bottoms of the plurality of sliding rods 502 is fixedly connected to the same moving frame 503. A pressure roller 504 is rotatably connected inside the moving frame 503. A plurality of springs 505 are fixedly connected between the moving frame 503 and the first mounting frame 501. The plurality of springs 505 are respectively located outside the plurality of sliding rods 502. Two trigger buttons 506 are fixedly connected to one side outer wall of the moving frame 503. One end of the moving frame 503 is located at the middle position between the two trigger buttons 506.
[0023] Both of the two trigger buttons 506 are electrically connected to the driving device of the take-up roller through wires, and the driving device is set as a speed-regulating motor.
[0024] One limiting roller 2 is fixedly installed on each of the two sides of the outer wall of the top of the bottom plate 1. Two receiving rollers 3 are fixedly installed at the middle position of the outer wall of the top of the bottom plate 1. The same film body 4 is sleeved on the two limiting rollers 2 and the two receiving rollers 3. The pressure roller 504 can press the upper surface of the film body 4.
[0025] If the film body 4 becomes slack during transmission, the pressure exerted by the film body 4 on the pressure roller 504 will also decrease. The compressed springs 505 will gradually recover their length, and the moving frame 503 and the pressure roller 504 will also be driven to press the film body 4, ensuring that the film body 4 can still remain taut during this period until the moving frame 503 presses on the outer trigger button 506. This trigger button 506 will then control the speed-regulating motor used to drive the take-up roller outside to rotate faster, and the insufficient film supply will gradually become taut again. The pressure it exerts on the pressure roller 504 will also increase accordingly, and the springs 505 will be compressed and shortened again. When the moving frame 503 presses the inner trigger button 506, the external speed-regulating motor will also return to its original speed. Thus, the film body 4 can always be kept in a taut state.
[0026] As Figure 1 、 Figure 2 and Figure 4 shown, a detection assembly 6 is installed on the top of the bottom plate 1. The detection assembly 6 is located at the middle position between the two receiving rollers 3.
[0027] The detection component 6 includes a second mounting bracket 601 fixedly connected to the outside of the bottom plate 1. The same bidirectional lead screw 604 is rotatably connected to the inner walls of the top and bottom of the second mounting bracket 601. Both ends of the bidirectional lead screw 604 are threadedly connected with an ultrasonic detector 603. The same limiting rod 602 is slidably inserted into one side of the two ultrasonic detectors 603. The limiting rod 602 is fixedly connected between the inner walls of the top and bottom of the second mounting bracket 601. The outer wall of the top of the second mounting bracket 601 is fixedly installed with a motor 605. The rotating shaft of the motor 605 is coaxially fixed to one end of the bidirectional lead screw 604. The ultrasonic detector 603 emits ultrasonic signals to the outside of the film body 4 and receives the reflected signals. By processing the signals, the topographic information outside the film body 4 can be obtained, and the uniformity of the surface of the film body 4 can be judged.
[0028] An ultrasonic generator 606 is fixedly installed on the outer wall of the top of the second mounting bracket 601. Both ultrasonic detectors 603 are electrically connected to the ultrasonic generator 606 through wires.
[0029] First, adjust the relative positions of the two ultrasonic generators 606 according to the specifications of the film body 4. By starting the motor 605 to drive the bidirectional lead screw 604 to rotate, the two ultrasonic detectors 603 will approach or move away from each other under the restriction of the limiting rod 602 and the drive of the bidirectional lead screw 604, so as to ensure that the detected pattern is clearer, which is beneficial to increasing the adaptability of the device. And the cooperation of the two ultrasonic detectors 603 can ensure that the detection result is more accurate.
[0030] The utility model provides a detection device for the research and development of a high-barrier biaxially stretched coextruded film. The specific working principle is as follows:
[0031] First, adjust the relative positions of the two ultrasonic generators 606 according to the specifications of the film body 4. By starting the motor 605 to drive the bidirectional lead screw 604 to rotate, the two ultrasonic detectors 603 will approach or move away from each other under the restriction of the limit rod 602 and the drive of the bidirectional lead screw 604, so as to ensure that the detected pattern is clearer, which is beneficial to improving the adaptability of the device. And the cooperation of the two ultrasonic detectors 603 can ensure that the detection result is more accurate. When the device works, the external winding roller starts to wind the film body 4 due to the start of the speed regulating motor. If the film body 4 becomes loose during transmission, the pressure exerted by the film body 4 on the pressure roller 504 will also decrease, and the compressed spring 505 will gradually recover its length. The moving frame 503 and the pressure roller 504 will also be driven to press the film body 4, ensuring that the film body 4 can still be kept taut during this period until the moving frame 503 presses against the trigger button 506 near the outside. The trigger button 506 will then control the speed regulating motor for driving the winding roller to rotate faster, and the insufficient film supply will gradually become taut again, and the pressure it exerts on the pressure roller 504 will also increase accordingly, and the spring 505 will be compressed and shortened again. When the moving frame 503 presses the inner trigger button 506, the external regulating motor will also return to its original speed. Thus, the film body 4 can always be kept taut.
[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
