Description
TECHNICAL FIELD
[0001] The utility model relates to daily necessities test technical field, concretely is a kind of disposable food cover use test device. BACKGROUND
[0002] Disposable food cover is also called disposable food preservative cover or disposable food dust cover, mainly by PE film and elastic band, elastic band is covered in the width direction both ends of PE film, PE film is folded and is fixed along the length direction with elastic band by ultrasonic wave.The film body is only unfolded when using, and is tightly attached to the surface of tableware through elastic band, can play certain preservative and dustproof effect, because of its convenient use, more and more consumers favour in daily life.But disposable food cover is often easily damaged in use, causes the trouble of consumer, there is no corresponding test standard or test equipment to evaluate the use performance of disposable food cover, this is also the difficult problem that perplexes the technical personnel. SUMMARY
[0003] In order to solve the above technical problem, the utility model provides a kind of disposable food cover use test device, it can conveniently complete the performance test of disposable food cover.
[0004] Its technical scheme is as follows: a kind of disposable food cover use test device, characterized in that, it includes base, extension track, sample support rod, the extension track is at least provided with two and is installed in the base, the sample support rod of each extension track is installed on the extension track and can be translated, the sample support rod is connected drive mechanism, the drive mechanism includes motor and transmission screw rod, the lower portion of the sample support rod is installed with the sliding block that is slidably matched with the extension track, the sliding block is threadedly matched with the transmission screw rod, and the sample support rod is provided with anti-drop mechanism.
[0005] Further characterized in that, the extension track includes four, and is evenly arranged in the base;
[0006] The anti-drop mechanism is the anti-drop spherical block that is arranged on the top of the sample support rod or the positioning notch that is opened in the sample support rod;
[0007] The positioning notch is provided with pressure sensor, and the pressure sensor is electrically connected to the motor.
[0008] After using the utility model, the food cover to be detected is supported on four sample support rods, when the sample support rod is outwardly supported, the distance that the sample support rod moves until the food cover breaks can be determined to determine the tensile force that the food cover can withstand, or the distance outwardly is preset, the sample support rod moves to the set distance to determine whether the food cover is qualified, so that the performance test of disposable food cover can be conveniently completed. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 It is the structure schematic view of the utility model;
[0010] Figure 2 It is the drive mechanism amplification schematic view of the utility model;
[0011] Figure 3 It is the sample support rod with positioning notch schematic view. DETAILED DESCRIPTION
[0012] See Figure 1 and Figure 2 As shown in the figure, a disposable food cover use test device includes base 1, extension track 2, sample support rod 4, extension track 2 includes four and is evenly installed on base 1, each extension track is installed with translatable sample support rod 4, and sample support rod 4 is connected with a drive mechanism. The drive mode of sample support rod 4 can adopt multiple forms, and the most common one is motor drive mode. Specifically, the drive mechanism includes motor 5 and transmission screw rod 6, the lower part of sample support rod 4 is installed with sliding block 7 that is in sliding cooperation with extension track 2, sliding block 7 is in threaded cooperation with transmission screw rod 6, the translation of sliding block 7 is realized by driving transmission screw rod 6 to rotate by motor 5, and finally the translation of sample support rod 4 is realized, and four motors 5 are synchronously driven. In order to prevent the food cover from falling off, the top of sample support rod 4 is provided with anti-falling spherical block 8, which can well hold the food cover. 9 in the figure is a dust cover.
[0013] Generally, the following mode can be adopted to detect the performance of the food cover.
[0014] The first kind: the food cover is supported and sleeved on the four sample support rods 4, at this time, the sample support rods 4 are in the position close to the center, the motor 5 is started, the four motors 5 work synchronously, drive the four sample support rods 4 to move outward, the food cover is supported and opened, until the food cover is broken, the distance moved by the sample support rods 4 at this time is recorded, according to the set relationship between the moving distance and the force, the moving distance can be converted into the outward supporting force, so as to obtain the force required for the food cover to be broken.
[0015] The second kind: a standard value of the moving distance of the sample support rod 4 is set in advance, the food cover is supported and sleeved on the four sample support rods 4, at this time, the sample support rods 4 are in the position close to the center, the motor 5 is started, the four motors 5 work synchronously, drive the four sample support rods 4 to move outward, the food cover is supported and opened, if the sample support rods 4 move to the set position, the food cover is still not broken, it is proved that the product is qualified, if the food cover is broken before the sample support rods 4 move to the set position, it is proved that the product is unqualified. Figure 3As shown, in order to more accurately determine the breakage of the food cover, a pressure sensor is installed in the positioning notch 3. The pressure sensor is electrically connected to the motor 5. Before the food cover breaks, the shrink tape can always press the pressure sensor. Once the breakage occurs, the tightening force of the shrink tape is released immediately, at least one pressure sensor is no longer under force, and the motor stops.
