DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] Embodiment one: please refer to Figures 1-6 The existing PVC film heat resistance detection device needs to place the PVC film on the detection device during detection, which is inconvenient for fixing the PVC film. In order to solve this technical problem, the embodiment discloses the following technical content.
[0025] The top front and rear sides and the left and right ends of the detection box 1 are fixedly connected with the connecting plates 2, and the threaded rods 3 are rotatably connected to the connecting plates 2. The upper surface of the detection box 1 is connected with the pressing plate 4, the bottom end of the pressing plate 4 is fixedly connected with the connecting plates 2 on the left and right sides, and the connecting plates 2 on the pressing plate 4 are threadedly connected with the threaded rods 3. The inside top end of the pressing plate 4 is fixedly connected with the glass plate 5.
[0026] During detection, the threaded rod 3 is rotated to move the pressing plate 4 upwards, then the PVC film is passed between the detection box 1 and the pressing plate 4, and then the threaded rod 3 is rotated again to move the pressing plate 4 downwards, so that the pressing plate 4 clamps the PVC film. Since the top end of the pressing plate 4 is fixedly connected with the glass plate 5, the heating detection condition of the PVC film can be observed.
[0027] Embodiment two: the existing PVC film heat resistance detection device has two modes during detection, which is inconvenient for adjusting the position of the heating device. Therefore, the embodiment is realized through the following technical scheme, as shown in Figures 1-6 .
[0028] The top end of the detection box 1 is fixedly connected with a moving device 6, and the moving device 6 is composed of a cross plate 601, a storage box 602, a motor 603, a lead screw 604, a limiting rod 605 and a first heating plate 606. The cross plate 601 is fixedly connected to the top right side of the detection box 1, and the front and rear sides of the cross plate 601 are fixedly connected with the storage box 602. The front right end of the storage box 602 is fixedly connected with the motor 603. The output shaft of the motor 603 is fixedly connected with the lead screw 604. The right end of the storage box 602 is fixedly connected with the limiting rod 605 inside. The inside of the storage box 602 is slidingly connected with the first heating plate 606. The left front end of the first heating plate 606 is threadedly connected with the lead screw 604. The left rear end of the first heating plate 606 is slidingly connected with the limiting rod 605. The lower surface of the first heating plate 606 is in close contact with the upper surface of the support rod 7. The inside top of the detection box 1 is fixedly connected with the support rod 7.
[0029] When the PVC film is heated for detection, the first heating plate 606 is located inside the detection box 1. The first heating plate 606 is turned on to heat the PVC film. The heat resistance of the PVC film can be detected. After the heat resistance is detected, the water vapor heating mode is changed. At this time, the motor 603 is started. The output shaft of the motor 603 drives the lead screw 604 to rotate, so that the lead screw 604 drives the first heating plate 606 to move to the right side. The first heating plate 606 moves to the right side of the detection box 1, so that the detection mode is changed.
[0030] In the existing PVC film heat resistance detection device, the water vapor heating mode is needed for PVC film detection. It is not convenient to add water vapor heating assistance. Therefore, the technical scheme is shown in Figure 3 、 Figure 4 and Figure 6 .
[0031] The inside bottom of the detection box 1 is fixedly connected with a second heating plate 8. The inside lower end of the detection box 1 is fixedly connected with a storage plate 9. The upper surface of the storage plate 9 is connected with a water tank 10.
[0032] There is water in the water tank 10. When the water vapor heating mode is started, the second heating plate 8 heats the water in the water tank 10. In the sealed space, water vapor is generated below the PVC film. At this time, it is the water vapor heating detection mode. After detection, the PVC film is taken out. If it is necessary to add water or replace the water in the water tank 10, the water tank 10 can be taken out from the top of the detection box 1 because the width of the water tank 10 is less than the width between the support rods 7. Water is added to the water tank 10.
[0033] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail here.
[0034] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
