Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a constant temperature testing device for the adhesion of medical tape. Background Technology

[0002] Adhesive tape consists of a substrate and an adhesive, used to bond two or more unconnected objects together. Due to its advantages such as ease of use, low cost, and high bonding reliability, it is widely used in industries such as medical materials and hygiene products. To evaluate the reliability and durability of adhesive tape, a tack test is required. This test uses a test frame, where the two ends of the tape are attached to opposite sides of an adhesive board, and weights are suspended at the bends. The displacement distance of the tape ends over a certain period is observed to determine the tape's quality. However, existing tack tests neglect the influence of ambient temperature. High or low temperatures can affect the tack of tape, thus compromising the accuracy of current tests and leading to inconsistent tape quality in the market. Utility Model Content

[0022] Example

[0023] Please see Figure 1 This embodiment provides a constant temperature testing device for the adhesion of medical tape, including a constant temperature chamber 1 and a test rack 2. The constant temperature chamber 1 is made of high-quality stainless steel argon arc welded inside, and high-quality steel plate is used for the outside of the chamber; specifically, it includes a first base 11, a chamber body 12, and a door 13. The chamber body 13 is set on the first base 11. The chamber body 12 has a test chamber 123 with a front opening. The test rack 2 is placed in the test chamber 123. The door 13 is pivotally connected to the front opening of the chamber body 12. A handle 131 is provided on the outer side of the door 13. A transparent observation area 132 is provided on the door 13. A blower is set in the first base 11. The air outlet of the blower is connected to the test chamber 123 and connected to the test rack 2 located in the test chamber 123. A suitable air duct within the test chamber 123 forms a hot air circulation system. The gaps in the constant temperature chamber 1 are sealed with a new type of synthetic silicon sealing strip, enabling the constant temperature chamber 1 to operate at high temperatures for extended periods. The front side of the first base 11 is equipped with a start switch 3 electrically connected to a blower and a temperature controller 4. The temperature controller 4 includes a temperature display screen 41, a temperature setting key 42, a heating key 43, and a cooling key 44. The chamber 12 is equipped with a ventilation hole 124 that connects to the test chamber 123. The temperature controller 4 is a microcomputer PID temperature controller with over-temperature deviation protection, digital display, and timing function.

[0024] Combination Figure 2 As shown, the test frame 2 includes a second base 21, a frame 22, and several adhesive boards 23. The frame 22 is mounted on the second base 21, and the several adhesive boards 23 are vertically suspended on the frame 22. The upper ends of the several adhesive boards 23 are connected to the front side of the crossbeam of the frame 22 by screws 24. Several buffer pads 25 are arranged in a matrix at the bottom of the second base 21. The box 12 is divided into a weight placement cavity 122 and a test chamber 123 by a partition 121. Several weights 5 with hooks are placed in the weight placement cavity 122 corresponding to the several adhesive boards 23.

[0025] Preferably, the front side of the crossbeam of the frame 22 is inclined, and the bottom of the crossbeam of the frame 22 forms a bottom angle of 2° to 10°. This inclined design can prevent the tape from peeling off from the adhesive plate 23 and allows the weight 5 to be suspended.

[0026] Preferably, the surface of the adhesive plate 23 is marked with graduations for easy observation.

[0027] In use, open the chamber door 13 using handle 131, remove the test rack 2 from the constant temperature chamber 1, and then attach both ends of the tape to be tested to the surface of the adhesive board 23. After attaching, put the test rack 2 back into the constant temperature chamber 1, then take the weight 5 from the weight placement cavity 122 and suspend it at the bottom end of the tape. Then close the chamber door 13, turn on the constant temperature chamber 1, adjust it to a suitable temperature using the temperature controller 4, and then observe the test performance of the tape over a certain period of time through the transparent observation area 132 on the chamber door 13 to determine the quality of the tape.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
