Technical Field

[0001] This utility model relates to adhesive tape, and in particular to a high temperature resistance testing device for PET adhesive tape. Background Technology

[0002] PET tape, also known as PET high-temperature tape, is a type of tape made of soft PET polyester film as the base material, coated with high-performance pressure-sensitive adhesive on one or both sides.

[0003] PET tape has good high and low temperature resistance and can be used in a wide temperature range. For example, some PET tapes can withstand temperatures up to 120℃ under long-term use, and some products can withstand temperatures as high as 150℃-200℃ for short-term use.

[0004] To ensure product quality, manufacturers need to conduct high-temperature resistance tests on samples of PET tape from the same batch before the tape leaves the factory, in order to verify the adhesion of the PET tape under high temperature conditions. However, how to intuitively judge the change in the adhesion of PET tape during the test has become an urgent problem to be solved. Utility Model Content

[0005] This invention proposes a high-temperature resistance testing device for PET tape, which solves the aforementioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is as follows: a high temperature resistance testing device for PET tape includes a base, a support platform is fixedly connected to the base, and a heating mechanism is installed inside the support platform.

[0007] A fixing mechanism that presses against the upper end of the support platform is installed on the base;

[0008] A feeding mechanism that moves up and down is provided above the support platform;

[0009] A stand is fixedly installed on the base, and a drive mechanism for driving the feeding mechanism is installed on the stand.

[0010] The base is equipped with a recycling mechanism.

[0011] A further feature of this invention is that the fixing mechanism includes two pressure rods, which press against the upper end of the support platform. Mounting plates are symmetrically fixed on the base, located behind the support platform. Rotating cylinders are mounted on both mounting plates, and the pressure rods are fixedly connected to the piston rod ends of the rotating cylinders.

[0012] A further feature of this invention is that the pressure rod includes a telescopic block;

[0013] The pressure rod has a downward-facing telescopic groove, and the telescopic block is slidably connected to the telescopic groove. Several springs are fixedly connected between the telescopic block and the bottom wall of the telescopic groove.

[0014] Several sheets of single-sided adhesive tape are glued to the lower end face of the telescopic block.

[0015] A further feature of this invention is that the heating mechanism includes an electric heating plate;

[0016] The support platform has a heating chamber, and the heating plate is installed inside the heating chamber.

[0017] A further feature of this invention is that the driving mechanism includes a transmission lead screw;

[0018] The stand has an installation groove, the transmission screw is rotatably connected to the installation groove, and a servo motor for driving the transmission screw is installed on the stand.

[0019] A further feature of this invention is that the feeding mechanism includes a hopper, the hopper includes a lifting plate, and the lifting plate is threadedly connected to the transmission screw.

[0020] A discharge pipe is fixedly connected to the lower side of the hopper, and a solenoid valve is installed on the discharge pipe.

[0022] A fan is mounted on the base, and the fan is located behind the support platform;

[0023] A baffle is provided on the front side of the recycling bin.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] The material is poured into the adhesive surface of the sample to be tested after being heated to a high temperature by a hopper, so that technicians can intuitively judge the viscosity under high temperature conditions by observing the amount of material adhering to the surface of the sample.

[0026] After the test is completed, the technicians only need to peel off the sample along with the bottom layer of single-sided adhesive tape to remove the sample, thus avoiding the adhesive on the sample adhering to the pressure bar and making it easier for the technicians to clean the equipment.

[0033] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Example:

[0035] like Figures 1 to 4 As shown, a high-temperature resistance testing device for PET tape includes a base 11, on which a support platform 12 is fixedly connected. Before starting the test, the technician lays the sample to be tested with the adhesive side facing up on the upper side of the support platform 12. A heating chamber 22 is provided inside the support platform 12, and an electric heating plate 21 for heating the sample to be tested during the test is installed inside the heating chamber 22.

[0036] Two symmetrical mounting plates 15 are fixedly connected to the base 11. The two mounting plates 15 are located behind the support platform 12. A rotating cylinder 16 is installed on each of the two mounting plates 15. A pressure rod 14 is fixedly connected to the end of the piston rod of each rotating cylinder 16. After the technician places the sample to be tested on the support platform 12, the pressure rod 14 swings downward under the drive of the rotating cylinder 16 until the pressure rod 14 presses against the surface of the sample to be tested, thereby fixing the sample to be tested.

[0037] A stand 13 is mounted on the base 11. An installation groove 24 is provided in the stand 13. A transmission screw 23 is rotatably connected in the installation groove 24. A servo motor 25 for driving the transmission screw 23 is mounted on the stand 13. A hopper 26 that can move up and down is provided above the support platform 12. The hopper 26 includes a lifting plate 32, which is threaded to the transmission screw 23. Technicians can first move the hopper 26 downward so that they can add plastic granules and other materials into the hopper 26.

[0038] Furthermore, a discharge pipe 27 is fixedly connected to the lower side of the hopper 26, and a solenoid valve 28 is installed on the discharge pipe 27. Technicians control the feeding of materials into the hopper 26 through the solenoid valve 28.

[0039] After the technicians fix the sample to be tested using the pressure bar 14, they heat the sample to the required temperature using the heating plate 21. Then, the hopper 26 moves downward to a suitable height and feeds material onto the surface of the sample to ensure that the surface of the sample can be covered with material.

[0040] It should be noted that the inner diameter of the discharge pipe 27 is relatively large to prevent the material from being unable to fall out of the discharge pipe 27 due to friction.

[0041] In addition, a recycling bin 31 with an upward-facing opening is installed on the base 11, and a fan 29 is installed on the base 11. The fan 29 is located behind the support platform 12. After the material is put into the hopper 26, the fan 29 blows the excess material that is not stuck to the surface of the sample to be tested into the recycling bin 31. In order to prevent the material from being blown off the base 11 by the fan 29 and to increase the cleaning workload of the technicians, a baffle 30 is provided on the front side of the recycling bin 31 to ensure that the material is not blown off to other places by the fan 29.

[0042] Because the sample to be tested will stick to the bottom of the pressure rod 14, it is not convenient for technicians to remove the tested sample and clean the bottom surface of the pressure rod 14 after the test. Therefore, as Figure 2 as well as Figure 4As shown, based on Embodiment 1, Embodiment 2 is proposed here: The pressure rod 14 has a downward-facing telescopic groove 18, and a telescopic block 17 is slidably connected in the telescopic groove 18. Several springs 19 are connected between the telescopic block 17 and the bottom wall of the telescopic groove 18. Several stacked single-sided adhesive tapes 20 are glued to the bottom of the telescopic block 17, and the non-adhesive side of the single-sided adhesive tapes 20 faces the support platform 12 and abuts against the sample to be tested.

[0043] During the test, due to the inherent stickiness of the sample, it adheres to the non-sticky side of the single-sided adhesive tape 20. After the test, the pressure rod 14 swings upward, thereby moving the sample away from the support platform 12. At this time, the technician observes the amount of material adhering to the surface of the sample to determine its stickiness under high temperature conditions. After observation, the technician only needs to peel off the sample and the bottom layer of single-sided adhesive tape 20 together to proceed with the next test.

[0044] As the single-sided adhesive tape 20 is consumed, the telescopic block 17 will move downward under the drive of the spring 19 to ensure that no matter how much single-sided adhesive tape 20 is left, the pressure rod 14 can fix the sample to be tested on the support platform 12.

[0045] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
