Description

Technical Field

[0001] This utility model relates to the field of flame retardant tape viscosity testing technology, specifically a flame retardant tape viscosity testing device. Background Technology

[0002] Flame-retardant tape is a type of tape with high adhesion and durability, widely used in various industrial fields. It is typically composed of a base material (such as polyester, polypropylene, or cloth) and an adhesive, capable of resisting various environmental factors such as temperature, humidity, and chemical corrosion. Industrial tapes play a vital role in packaging, fixing, protection, sealing, and marking. With societal development, tapes are increasingly used in various fields. After production, tapes require sampling and testing.

[0003] A tape viscosity testing device, as described in application number CN202322809428.8, includes a device body and a pull-up assembly. The device body includes an operating frame and a top frame. The pull-up assembly includes a cylinder, a force gauge, a gooseneck rod, a pull-up member, and a receiving groove. The top frame has cutting components on both sides of its top end. Each cutting component includes two cutting grooves, which are symmetrically distributed around the receiving groove at the top of the operating frame. A mounting bracket is fixedly installed on the front of the operating frame. This invention, by incorporating cutting components, allows for the cutting of both ends of the tape after adhesion by rotating two cutting blades. This ensures that the tape at the top of the receiving groove is perpendicular to the center of the receiving groove, resulting in more accurate and stable data when the pull-up member applies force to the tape. However, this testing device requires the tester to manually tear the tape and place it on the surface of the device. During the tearing process, the sticky side of the tape is prone to contact with clothing or other materials, which will affect the stickiness. In addition, the functionality of this testing device is relatively limited, as it can only test the viscosity of the tape, and its application range is small.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a device for detecting the viscosity of flame-retardant tape. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting the viscosity of flame-retardant tape, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flame-retardant tape viscosity testing device, comprising an inclined plate and a groove, characterized in that the inner surface of the inclined plate is provided with a groove, and a driving mechanism is provided inside the groove, and a strength testing mechanism is fixedly connected to the bottom of the inclined plate, and a cylinder is fixedly connected to the top of the driving mechanism.

[0007] Preferably, the driving mechanism includes a driver fixedly connected to the top position of the outer surface of the inclined plate, and a driving rod fixedly connected to the output end of the driver. The driving rod is threadedly connected to a moving block, and a slider is fixedly connected to one side of the moving block. The strength testing mechanism includes a spring fixedly connected to the bottom position of the inclined plate, and a connecting plate fixedly connected to one end of the spring. A hook is fixedly connected to the bottom of the connecting plate, and a weight is sleeved on the outside of the hook.

[0008] Preferably, a guide rod is fixedly connected to the top of the inclined plate, and a guide block is slidably connected to the outside of the guide rod. A clamp is fixedly connected to the top of the inclined plate, and a fixing frame is fixedly connected to the top of the inclined plate.

[0009] Preferably, a lifting plate is fixedly connected to one side of the guide block, and a mounting bracket is fixedly connected to the bottom of the lifting plate.

[0010] Preferably, the outer surface of the mounting bracket is rotatably connected to the tape body, and a rotating shaft is fixedly connected to one side of the inclined plate, and a cutting blade is fixedly connected to one side of the rotating shaft.

[0011] Preferably, the fixed frame is rotatably connected to a rotating block, and the bottom of the rotating block is fixedly connected to a limiting ring, and the bottom of the inclined plate is fixedly connected to a supporting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of the drive mechanism and the cylinder at the top of the drive mechanism, eliminates the need for testers to remove the tape from the outside of the tape body and lay it flat on the outside of the inclined plate. The drive mechanism directly pulls the tape body, so that the tape outside the tape body is automatically laid flat on the inclined plate for viscosity testing. This avoids the process of removing the tape, where the sticky side of the tape comes into contact with other substances, resulting in reduced viscosity and errors in the viscosity test results. In addition, the cylinder can be adjusted according to the thickness of the tape body to ensure that the non-sticky side of the tape is in close contact with the inclined plate, avoiding the generation of air bubbles, which would cause resistance when the ball rolls and require retesting.

[0014] 2. This utility model improves the functionality of the device by setting up a strength test. After the viscosity test of the tape is completed, one side of the tape is wrapped around the outside of the strength test. By adding different weights, the tensile strength of the tape is tested, thus improving the functionality of the device. Tensile strength test can be performed at the same time as the viscosity test of the tape, realizing multiple integrated testing functions.

[0015] 3. By setting up a guide rod and a cutting blade, this utility model improves the stability of the lifting plate by moving along the guide rod during the lifting process driven by the cylinder. This ensures that the lifting plate remains parallel to the inclined plate. When the tape is stretched to a certain length, the cutting blade directly cuts the tape, providing convenience for testing and improving testing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, a flame-retardant tape viscosity testing device includes an inclined plate 1 and a groove 2. The groove 2 is formed on the inner surface of the inclined plate 1, and a driving mechanism 3 is set inside the groove 2. A strength testing mechanism 4 is fixedly connected to the bottom of the inclined plate 1, and a cylinder 5 is fixedly connected to the top of the driving mechanism 3. Slide rails are formed on both sides of the groove 2. The driving mechanism 3 is located inside the two sets of grooves 2 and is symmetrically distributed. The tape is pulled to spread flat on the surface of the inclined plate 1. The cylinder 5 adjusts the height of the lifting plate 8 according to the thickness of the tape on the outside of the tape body 10, so that the tape is laid tightly against the inclined plate 1 to avoid the generation of air bubbles.

[0023] like Figures 3-4 As shown, the drive mechanism 3 includes a driver 301 fixedly connected to the top of the outer surface of the inclined plate 1, and a drive rod 302 fixedly connected to the output end of the driver 301. A movable block 303 is threadedly connected to the drive rod 302, and a slider 304 is fixedly connected to one side of the movable block 303. The driver 301 provides power to the drive rod 302, which drives the slider 304 to move. The slider 304 is symmetrically distributed about the movable block 303. The slider 304 is slidably connected to a slide rail formed on the inner surface of the groove 2, and the slider 304 restricts the movement of the movable block 303, preventing... The non-moving block 303 flips during movement. The strength testing mechanism 4 includes a spring 401 fixedly connected to the bottom of the inclined plate 1, and a connecting plate 402 fixedly connected to one end of the spring 401. A hook 403 is fixedly connected to the bottom of the connecting plate 402, and a weight 404 is sleeved on the outside of the hook 403. Two sets of symmetrical hooks 403 are provided at the bottom of the connecting plate 402 to ensure the balance of the connecting plate 402. The tape can be wrapped around the outside of the inclined plate 1 in the opposite direction. The tensile strength of the tape is judged by continuously changing the weights 404 of different weights on the outside of the hooks 403.

[0024] Furthermore, a guide rod 6 is fixedly connected to the top of the inclined plate 1, and a guide block 7 is slidably connected to the outside of the guide rod 6. A lifting plate 8 is fixedly connected to one side of the guide block 7, and a mounting bracket 9 is fixedly connected to the bottom of the lifting plate 8. The guide rod 6 is parallel to the cylinder 5 and perpendicular to the inclined plate 1, assisting the lifting rod in completing the lifting operation. A placement rod is provided at the bottom of the mounting bracket 9. The placement rod is detachable, and the tape body 10 is placed outside the placement rod. The tape body 10 is rotatably connected to the outer surface of the mounting bracket 9. A rotating shaft 11 is fixedly connected to one side of the inclined plate 1, and a cutting blade 12 is fixedly connected to one side of the rotating shaft 11. The rotating shaft 11 can rotate, and the cutting blade 12 contacts the surface of the inclined plate 1. The cutting blade 12 can be replaced to ensure sharpness when cutting the tape.

[0025] Furthermore, a clamp 13 is fixedly connected to the top of the inclined plate 1, and a fixed frame 14 is fixedly connected to the top of the inclined plate 1. A rotating block 15 is rotatably connected to the outside of the fixed frame 14, and a limiting ring 16 is fixedly connected to the bottom of the rotating block 15. A support base 17 is fixedly connected to the bottom of the inclined plate 1. The clamp 13 clamps and fixes one end of the tape. The limiting ring 16 has a certain weight, so that the rolling ball will not suddenly roll off when placed inside the limiting ring 16.

[0026] Working principle: When using this flame-retardant tape viscosity testing device, first disassemble the mounting frame 9, place the tape body 10 with the tape on the outer surface of the mounting frame 9, then remove one end of the tape and fix it inside the clamp 13. Adjust the cylinder 5 according to the thickness of the tape, so that the guide block 7 on one side of the lifting plate 8 moves up and down along the guide rod 6. When the tape is tightly connected to the inclined plate 1, the drive mechanism 3 inside the groove 2 is activated. The driver 301 drives the moving block 303 outside the drive rod 302 to move. At this time, the tape body 10 inside the mounting frame 9 moves, and the tape body 10 outside the groove 2 moves. The adhesive tape is laid flat on the surface of the inclined plate 1, and then wrapped around the outside of the connecting plate 402. The tape is cut by the cutter 12 on one side of the rotating shaft 11. Then, rolling balls of different weights are placed inside the limiting ring 16. The rotating block 15 inside the fixing frame 14 is rotated, and the limiting ring 16 is lifted. The rolling balls roll off the surface of the tape. The adhesiveness of the tape is judged according to the position where the rolling balls stop. Finally, weights 404 of different weights are placed outside the hook 403 of the strength testing mechanism 4 to test the tensile properties of the tape. This is the working principle of the flame retardant tape viscosity testing device.
