Description

Technical Field

[0001] The utility model belongs to the technical field of film production, and in particular relates to a thickness dimension detection device for film production. Background Art

[0002] Polypropylene film is made by first passing the melt of high molecular weight polypropylene through a narrow and long die to form a sheet or thick film, then stretching it in two vertical directions (longitudinal and transverse) simultaneously or step by step in a special stretching machine, and then undergoing appropriate cooling or heat treatment or special processing (such as corona, coating, etc.). Polypropylene film is widely used in food packaging, fiber packaging and other packaging fields due to its excellent optical properties, mechanical properties and packaging adaptability.

[0003] At present, most of the thickness dimension detection equipment used in film production uses the method of laying the film flat on the workbench and then performing contact detection through the film thickness meter body. However, this detection method has some problems:

[0004] 1. Wrinkles affect accuracy: When a flat film is tested on a workbench, wrinkles are likely to form. These wrinkles will cause the surface of the film to be uneven, affecting the actual thickness measurement accuracy of the film. The presence of wrinkles prevents the film thickness meter from directly contacting the film surface, resulting in inaccurate measurement results.

[0005] 2. Influence of external environment: When the film is laid flat on the workbench and exposed to the external environment, it will be affected by factors such as wind, which will cause the film to deform. The deformation of the film will affect the accuracy of the measurement results and even cause deviations in the measurement data, resulting in production quality problems;

[0006] 3. Instability: Placing the film on the workbench for measurement can easily cause the film to be unstable. Even a slight movement can affect the measurement results. The film may move or twist slightly during the flattening process due to instability, further affecting the accuracy and stability of the measurement.

[0007] In summary, the existing thickness dimension detection equipment used in film production has problems such as wrinkle influence, external environmental interference and instability during use. These shortcomings affect the accuracy and stability of detection, and it is necessary to seek improvement solutions to improve the efficiency and accuracy of film thickness dimension measurement.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-5As shown, the specific design of the above-mentioned key components is described in detail below: a thickness dimension detection device for film production, including a bottom platform 1, two groups of end drive mechanisms are symmetrically arranged near the end positions of the bottom platform 1, one group of end drive mechanisms is provided with two clamping plates 6, two groups of middle drive mechanisms are arranged on the bottom platform 1, the two groups of middle drive mechanisms are symmetrically arranged with the center of the bottom platform 1, one group of middle drive mechanisms is provided with two guide plates 18, and a pressure wheel 19 is arranged on the guide plate 18, and two beams 7 are symmetrically arranged on the bottom platform 1, and the beams 7 are symmetrically arranged with the center of the bottom platform 1, and electric slide rails 8 are arranged on the two beams 7 (the electric slide rails 8 are prior art and can be obtained by purchase or customization, and will not be described in detail in this article) micro electric push rods 9 are arranged on the sliders of the electric slide rails 8, and the micro electric push rod 9 on one beam 7 is provided with a contact plate 10, and the micro electric push rod 9 on the other beam 7 is provided with a transverse plate 11, and the transverse plate 11 is provided with a film thickness The instrument body 12, the end driving mechanism drives the two clamping plates 6 to move towards each other, the middle driving mechanism drives the guide plate 18 to move towards each other, the micro-electric push rod 9 on the beam frame 7 drives the contact plate 10 to move horizontally, and the micro-electric push rod 9 on the other beam frame 7 can drive the transverse plate 11 to move, and the transverse plate 11 then drives the film thickness instrument body 12 to move horizontally. First, the film is placed in the gap between the two pressure wheels 19, and then the film is passed through the pressure wheels 19 and clamped and fixed by the clamping plate 6. At this time, the film is in a fixed clamping state, and then the micro-electric push rod 9 pushes out the contact plate 10 so that the contact plate 10 directly contacts the film, and then the micro-electric push rod 9 on the other beam frame 7 pushes out the transverse plate 11, so that the film thickness instrument body 12 contacts the film, and the thickness of the film is measured. Such a design structure is stable and balanced, can effectively resist external interference and deformation, ensure the stability and reliability of the equipment during operation, and improve the accuracy and efficiency of measurement.

[0027] In order to avoid direct contact damage to the film when the film thickness meter body 12 is pushed out, two rubber piers 13 are symmetrically arranged on the transverse plate 11. The rubber piers 13 play a shock-absorbing and buffering role, and also avoid direct contact damage to the film by the film thickness meter body 12 pushed out by the micro electric push rod 9.

[0028] In order to ensure that the end driving mechanism can run smoothly and drive the clamping plate 6 to move, the end driving mechanism includes an end motor 2, an end threaded rod 3, an end slider 4, an end bearing seat 5 and a clamping plate 6. The end motor 2 is symmetrically arranged on the bottom platform 1, and one end of the end threaded rod 3 is symmetrically arranged on the output end of the end motor 2. The end slider 4 is slidably arranged on the end threaded rod 3 and the end motor 2 is close to the two ends of the bottom platform 1. The end bearing seat 5 is arranged on the bottom platform 1 and between the center positions of the two end motors 2. The end threaded rod 3 is connected to the end bearing seat 5 at one end away from the end motor 2. The clamping plate 6 is arranged above the end slider 4, and the end motor 2 starts to rotate. Then the end slider 4 moves under the action of the end threaded rod 3, thereby driving the clamping plate 6 to move, so that the clamping plate 6 can clamp the film, thereby playing a fixed clamping role and improving the stability of the film.

[0029] In order to enable the middle driving mechanism to drive the guide plate 18 to move, the middle driving mechanism includes a middle motor 14, a middle threaded rod 15, a middle slider 22, a middle bearing seat 20, a joint plate 21, a sliding groove 17 and a middle drag block 16.

One end of the middle threaded rod 15 is connected to the output end of the middle motor 14. The middle slider 22 is slidably arranged on the middle threaded rod 15. The middle bearing seat 20 is arranged on the bottom platform 1 and is located between the two middle motors 14. The end of the middle threaded rod 15 away from the middle motor 14 is connected to the middle bearing seat 20. The joint plate 21 is arranged on both sides of the middle slider 22. The sliding groove 17 is opened on the bottom platform 1 and is located on both sides of the middle threaded rod 15. The middle drag block 16 is slidably arranged in the sliding groove 17, and the side of the middle drag block 16 is fixedly connected to the connecting plate 21. The middle motor 14 is started to drive the middle threaded rod 15 to rotate and then drive the middle slider 22 to move. The middle slider 22 moves and then drives the middle drag block 16 to move in the sliding groove 17 through the connecting plate 21. The middle drag block 16 then drives the guide plate 18 to move. The guide plate 18 moves a certain distance to make the pressure wheel 19 contact the film, so that the film moves according to the trajectory of the pressure wheel 19. The guide plate 18 is n-shaped. The n-shaped design allows the guide plate 18 to be provided with two rows of pressure wheels 19 in the upper and lower rows, thereby ensuring that the movement and guiding function of the film is more accurate and convenient. The inner side of the clamping plate 6 is plate-shaped, and the plate-shaped design enables the film to be better contacted and clamped.
