[0001] The utility model relates to the technical field of aging detection, in particular to a PET film high-temperature aging detection box. Background Art

[0002] PET film is a commonly used plastic film material with good mechanical properties, heat resistance and chemical stability. High temperature aging test is a method to evaluate the heat resistance of PET film, which aims to check the service life and performance changes of PET film under high temperature conditions. Aging equipment usually adopts high temperature aging box or aging chamber.

[0003] Existing high-temperature aging test boxes usually lay the PET film flat on a placement plate to heat it, but one side of the PET film is exposed to the air and the other side is exposed to the placement plate, which may cause the PET film to be heated unevenly. In addition, if the PET film fails the high-temperature aging test, the excessively high temperature may cause the PET film to melt and drip into the test box, which is difficult to clean. Utility Model Content

[0004] In view of the problems existing in the background technology, a PET film high-temperature aging detection box is proposed.

[0005] The utility model provides a PET film high temperature aging detection box, comprising a box body. A heating mechanism is arranged in the box body.

A receiving plate is arranged below the clamping assembly and connected to the inner wall of the box body and receives the melted and dripped PET film. And a cleaning assembly is arranged above the receiving plate and cleans the melted PET film on the receiving plate.

[0006] Preferably, the clamping components, receiving plates and cleaning components are arranged in multiple groups in the box.

[0007] Preferably, the clamping assembly includes a telescopic mechanism with a fixed end arranged on the inner wall of the box; the telescopic end of the telescopic mechanism is connected to a lower clamping plate; a threaded rod 1 is rotatably connected to the lower clamping plate; the top end of the threaded rod 1 is connected to a knob, and an upper clamping plate is also threadedly connected thereto.

[0008] Preferably, the cleaning assembly includes driving mechanisms symmetrically arranged on the inner wall of the box; the driving ends of the two driving mechanisms are connected to two threaded rods; the other ends of the two threaded rods are rotatably connected to limit plates arranged on the inner wall of the box, and connecting blocks are threadedly connected thereto; a heater for heating the PET film to melt the PET film, and a scraper for scraping off the melted PET film are commonly connected between the two connecting blocks.

[0009] Preferably, the scraper is arranged at an angle, and the lower end of the scraper abuts against the upper surface of the receiving plate.

[0010] Preferably, one end of the receiving plate close to the deep end of the box body is open, and a collecting box for collecting the PET film scraped off by the scraper is provided below the opening.

[0011] Preferably, compared with the scraper, the heater is arranged on a side of the connecting block close to the collecting box.

[0012] Preferably, a groove is provided on the inner wall of the box body; a hook is provided on the collection box and is engaged with the groove, and a detachable connection between the collection box and the box body is achieved through the engagement.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] (1) The PET film high temperature aging test box is provided with a cleaning component, so that the heater first melts the solidified PET film, and then the scraper scrapes the melted PET film into the collection box to prevent the scraper from being unable to scrape the PET film after the PET film solidifies, and finally the collection box is removed for unified cleaning. The melted PET film can be scraped off to prevent the PET film from adhering to the receiving plate and being difficult to clean.

[0015] (2) The PET film high-temperature aging test box drives the threaded rod to rotate by rotating the knob, so that the upper clamping plate moves down along the threaded rod, clamping the PET film between the lower clamping plate and the upper clamping plate, thereby fixing the PET film. The lower clamping plate and the upper clamping plate are heat-insulating, which can prevent the PET film from adhering to the lower clamping plate and the upper clamping plate after melting and being difficult to remove. The middle part of the PET film is suspended in the air, which can make the PET film heated more evenly, thereby making the high-temperature aging test result more accurate.

[0022] Embodiment 1

[0023] like Figure 1-3 As shown, the utility model proposes a PET film high temperature aging detection box, including a box body 1, a clamping assembly 2, a receiving plate 3 and a cleaning assembly 4. A heating mechanism is arranged in the box body 1, and the heating mechanism is a resistance wire. The clamping assembly 2 is symmetrically arranged in the box body 1 to clamp the PET film. The receiving plate 3 is arranged below the clamping assembly 2 and connected to the inner wall of the box body 1 to receive the melted and dripping PET film. The cleaning assembly 4 is arranged above the receiving plate 3 to clean the melted PET film on the receiving plate 3. The clamping assembly 2, the receiving plate 3 and the cleaning assembly 4 are all arranged in multiple groups in the box body 1. High temperature aging detection can be performed on multiple PET films at the same time, increasing the practicality of the detection box.

[0024] Further explanation, the clamping assembly 2 includes a telescopic mechanism 21 with a fixed end arranged on the inner wall of the box body 1, and the telescopic mechanism 21 is a cylinder; the telescopic end of the telescopic mechanism 21 is connected to a lower clamping plate 22; a threaded rod 23 is rotatably connected to the lower clamping plate 22; the top of the threaded rod 23 is connected to a knob 24, and an upper clamping plate 25 is also threadedly connected thereto. The telescopic mechanism 21 enables the clamping assembly 2 to clamp PET films of different sizes, and has a wide range of applications. At the same time, the lower clamping plate 22 and the upper clamping plate 25 are heat-insulating settings to prevent the PET film from adhering to the lower clamping plate 22 and the upper clamping plate 25 after melting and being difficult to remove, and the middle part of the PET film is suspended in the air, so that the PET film can be heated more evenly, thereby making the high-temperature aging test results more accurate.

[0025] Embodiment 2

[0026] like Figure 1-2 and Figure 4-5As shown, the utility model proposes a PET film high temperature aging detection box. Compared with the first embodiment, this embodiment also includes: the cleaning component 4 includes a driving mechanism 41 symmetrically arranged on the inner wall of the box body 1, and the driving mechanism 41 is a motor; the driving ends of the two driving mechanisms 41 are connected to the threaded rod 2 42; the other ends of the threaded rod 2 42 are rotatably connected to the limit plate 43 arranged on the inner wall of the box body 1, and the connection block 44 is threadedly connected thereon; the two connection blocks 44 are commonly connected with a heater 46 for heating the PET film to melt the PET film, and the heater 46 is an electric heater, and a scraper 45 for scraping the melted PET film. The scraper 45 is arranged at an angle, and the lower end of the scraper 45 is against the upper surface of the receiving plate 3. The PET film that melts and drips on the receiving plate 3 can be scraped off to prevent the PET film from adhering to the receiving plate 3 and being difficult to clean.

[0027] Further explanation, the receiving plate 3 is open at one end close to the deep end of the box body 1, and a collection box 5 is arranged below the opening to collect the PET film scraped off by the scraper 45. A groove is arranged on the inner wall of the box body 1; a hook 501 is arranged on the collection box 5 to engage with the groove, and the collection box 5 is detachably connected to the box body 1 through the engagement. Compared with the scraper 45, the heater 46 is arranged on the side of the connection block 44 close to the collection box 5. The heater 46 melts the solidified PET film first, and then the scraper 45 scrapes the melted PET film into the collection box 5, which can prevent the scraper 45 from being unable to scrape the PET film after the PET film solidifies, and finally the collection box 5 is removed for unified cleaning.

[0028] The working principle of the utility model is as follows: when working, first start the telescopic mechanism 21, so that the telescopic end of the telescopic mechanism 21 is extended to a length suitable for the width of the PET film, and then the two ends of the PET film are respectively placed between the lower clamping plate 22 and the upper clamping plate 25 on both sides, and then rotate the knob 24 to make the knob 24 drive the threaded rod 23 to rotate on the lower clamping plate 22, so that the upper clamping plate 25 moves down along the threaded rod 23, and the PET film is clamped between the lower clamping plate 22 and the upper clamping plate 25, so that the PET film is fixed, and finally the box door of the box body 1 is closed and the heating mechanism is started to perform high-temperature aging detection on the PET film.

[0029] After the test is completed, the heating mechanism is first turned off and the box 1 is left to stand for a period of time to allow the heat in the box 1 to dissipate, so as to prevent the PET film from further melting. When the PET film is no longer melted, the driving mechanism 41 is started to drive the threaded rod 42 to rotate, so that the connecting block 44 drives the scraper 45 and the heating mechanism 46 to move toward the collecting box 5, and the heating mechanism 46 is started at the same time, so that the heater 46 first melts the solidified PET film, and then the scraper 45 scrapes the melted PET film into the collecting box 5, which can prevent the scraper 45 from being unable to scrape the PET film after the PET film solidifies, and finally the collecting box 5 is removed for unified cleaning.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
