Description

Technical Field

[0001] The utility model relates to the technical field of sealants, in particular to a sealant tear strength detection device. Background Technique

[0002] A sealant is an adhesive with a sealing function, usually used to fill, seal and bond the surfaces of various materials, playing roles such as waterproofing, moisture-proofing, heat insulation, and sound insulation. Sealants are widely used in various fields such as construction, automobiles, aerospace, and electronic equipment. Sealant tear strength detection is a test method used to evaluate the tear resistance of sealants under the action of force. In this test, a certain tensile force is usually applied to the sealant and an attempt is made to tear it to determine its ability to withstand tearing. This test method can help measure the resistance of the sealant to tensile force and tearing during actual use to ensure that it can effectively play the roles of sealing and fixing. Tear strength detection provides important information about the mechanical properties and durability of the sealant, helping designers select the most suitable materials for specific applications. According to the tear strength test results of the sealant, manufacturers can adjust and improve the production process and formula to improve product quality and performance.

[0003] When performing tear strength detection on a sealant tape, when the sealant is torn as the tensile force increases, the broken sealant tape suddenly loosens and may fly or rush towards people around, causing accidental injuries. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealant tear strength detection device, which has the advantage of restricting the movement range of the broken sealant tape when detecting the sealant tape, avoiding the broken sealant tape from endangering the safety of the staff observing beside, and solving the problem that the sudden tearing of the sealant tape is likely to affect the safety of the staff.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A sealant tear strength detection device includes a bottom plate and a screw sleeve. On both sides of the top of the bottom plate, fixing plates are welded. Two bearing one are embedded in the two fixing plates. The inner rings of the two bearing one are fixedly installed with lead screws. On the top of the bottom plate on the opposite sides of the two lead screws, a partition plate is welded. The two screw sleeves are meshed with the two lead screws. On the top of the two screw sleeves, tensile force detectors are installed. On the opposite ends of the two tensile force detectors, connecting plates are installed. A chute two is opened on the front side of the bottom plate. Two slider two are slidably connected to the chute two. On the top of the two slider two, brackets are welded. On the top of the two brackets, transparent covers are installed.

[0006] When using a sealant tear strength detection device in this technical solution, the fixed seat provides a supporting force for the bottom plate. The sealant tape to be detected is passed through two transparent covers, and both ends of the sealant tape are placed between two groups of clamping plates. Two groups of air cylinders push the two groups of clamping plates to move to clamp and fix both ends of the sealant. The two sliders II slide in the chute II, and the two sliders II drive the two transparent covers to move to a suitable position through two brackets. After adjusting the two transparent covers to a suitable position according to the actual situation, the servo motor drives the lead screw on one side of the top of the bottom plate to rotate through the transmission structure. The rotating lead screw drives another lead screw to rotate through the bearing II. The two nuts move in opposite directions on the two rotating lead screws. The two nuts drive the two tensile detectors to move. The two tensile detectors pull the sealant tape through the clamping plates. As the nuts move, a continuous tensile force is applied to the sealant tape until the sealant tape is torn. The staff can understand the tear resistance of the sealant tape according to the data displayed on the two tensile detectors.

[0007] Preferably, the partition is embedded with a bearing II, and both opposite ends of the two lead screws are fixedly connected to the inner ring of the bearing II. The external threads of the two lead screws are distributed in opposite directions. The two lead screws are fixedly connected through the bearing II. When one lead screw rotates, it drives the inner ring of the bearing II to rotate, and the inner ring of the bearing II drives the other lead screw to rotate. The two nuts can move in opposite or relative directions on the two lead screws.

[0008] Preferably, a servo motor is installed on the side of the bottom plate, and the transmission structure of the servo motor is fixedly connected to the lead screw on one side of the top of the bottom plate. The servo motor drives the lead screw on one side of the top of the bottom plate to rotate through the transmission structure.

[0009] Preferably, a slider I is installed at the bottom of each of the two nuts, and two chutes I are symmetrically arranged at the top of the bottom plate. The two sliders I are slidably connected to the two chutes I. The two sliders I provide a supporting force for the two nuts. When the two nuts move on the two lead screws, the two sliders I slide in the two chutes I to prevent the two nuts from rotating.

[0010] Preferably, air cylinders are symmetrically installed on the opposite sides of the two connecting plates, and clamping plates are installed at the opposite ends of the two groups of air cylinders. Both ends of the sealant tape are placed between the two groups of clamping plates, and the two groups of air cylinders push the two groups of clamping plates to move to clamp and fix both ends of the sealant.

[0011] Preferably, a distance is left between the two groups of clamping plates and the sides of the two connecting plates. When the two groups of clamping plates move, they will not interfere with the two connecting plates.

[0012] Preferably, both sides of the two transparent covers are penetrated. The sealant tape can pass through the two transparent covers.

[0013] Preferably, fixing seats are installed at the four corners of the bottom of the bottom plate, and the fixing seats are perpendicular to the bottom of the bottom plate. The fixing seats provide support for the bottom plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] By setting the second slider and the transparent cover, when detecting the tearing of the sealing tape, the two second sliders move in the two second chutes to adjust the two transparent covers to appropriate positions, and the sealing tape to be detected is passed through the two transparent covers. During the tearing process, the staff can observe the tearing situation of the sealing tape inside the two transparent covers. After the sealing tape is broken, the sealing tape will bounce into the two transparent covers, and the two transparent covers limit the movement range of the two sections of the sealing tape, achieving the effect of restricting the movement range of the broken sealing tape during the detection of the sealing tape and preventing the broken sealing tape from harming the staff observing nearby.
