[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A flame-retardant composite board peel strength testing device includes a base 1, a flame-retardant composite board body 2 and a fixing component 3 that cooperates with the flame-retardant composite board body 2 are provided on the top of the base 1, and a testing component 4 is provided on the top of the fixing component 3.
[0027] The fixing component 3 includes a first hollow plate 301 and a second hollow plate 302. Vacuum pumps 303 are fixedly connected to the top of the first hollow plate 301 and the bottom of the second hollow plate 302. The suction ports of the two vacuum pumps 303 are connected to suction pipes 304. The other ends of the two suction pipes 304 are connected to the top of the first hollow plate 301 and the bottom of the second hollow plate 302, respectively. Vacuum suction cups 305 are connected to the bottom of the first hollow plate 301 and the top of the second hollow plate 302. The side of the vacuum suction cup 305 closest to the flame-retardant composite plate body 2 is in close contact with the flame-retardant composite plate body 2.
[0028] In this embodiment: by setting a base 1, a flame-retardant composite board body 2, a fixing component 3, and a detection component 4, in use, the base 1 can support and fix the fixing component 3 and the detection component 4. The fixing component 3 can easily and stably fix the upper and lower layers of the flame-retardant composite board body 2 that need to be tested for peel strength. The fixing method is relatively simple to operate and will not damage the layers of the flame-retardant composite board body 2, which brings convenience to the operator. The detection component 4 can perform peel strength testing on the fixed flame-retardant composite board body 2, which can accurately reflect the peel strength of the composite board. Moreover, the structure is relatively simple and the operation is relatively easy, which can effectively improve the testing efficiency.
[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the detection component 4 includes a support frame 401. The two sides of the bottom of the support frame 401 are fixedly connected to the two sides of the top of the base 1. A hydraulic cylinder 402 is fixedly connected to the top of the support frame 401. The output rod of the hydraulic cylinder 402 passes through the support frame 401 and is fixedly connected to a tension sensor 403. A cross fixing bracket 404 is fixedly connected to the bottom of the tension sensor 403. The four sides of the bottom of the cross fixing bracket 404 are fixedly connected to the four sides of the top of the first hollow plate 301.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a tension display 405 for use with a tension sensor 403 is fixedly connected to the right side of the top of the support frame 401, and the tension sensor 403 and the tension display 405 are electrically connected.
[0031] Specifically, such as Figure 4 As shown, the top of the support frame 401 is provided with a through hole 406 for use with the hydraulic cylinder 402, and the output rod of the hydraulic cylinder 402 is slidably connected to the inner wall of the through hole 406.
[0032] In this embodiment: by setting up a support frame 401, a hydraulic cylinder 402, a tension sensor 403, a cross-shaped fixing frame 404, a tension display 405, and a through hole 406, in use, the support frame 401 can support and fix the hydraulic cylinder 402. After fixing the upper and lower layers of the flame-retardant composite board body 2 that needs to be peeled, the hydraulic cylinder 402 can be activated, causing the output rod of the hydraulic cylinder 402 to move the tension sensor 403 upward. The tension sensor 403 moves the cross-shaped fixing frame 404 upward, which in turn moves the first hollow plate 301 upward, thereby... By applying tensile force to the layers of the flame-retardant composite board body 2, the peel strength of the flame-retardant composite board body 2 can be tested. During the peeling process, the tensile sensor 403 can detect the magnitude of the tensile force in real time, convert the tensile force signal into an electrical signal, and transmit the electrical signal to the tensile force display 405. The tensile force display 405 can display the specific value of the tensile force in real time. The operator can intuitively observe the change of tensile force during the peeling process and record relevant data such as the maximum tensile force value for subsequent calculation of the peel strength of the composite board. This testing structure is relatively simple and easy to operate, which can effectively improve the testing efficiency.
[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, support bars 5 are fixedly connected to the four corners of the bottom of the second hollow plate 302, and the bottom of the support bars 5 is fixedly connected to the top of the base 1.
[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, there are several vacuum suction cups 305, which are evenly distributed at the bottom of the first hollow plate 301 and the top of the second hollow plate 302.
[0035] In this embodiment: by setting support bars 5, the second hollow plate 302 can be supported and fixed, and by setting multiple vacuum suction cups 305, the fixing stability of the flame-retardant composite plate body 2 can be improved.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the flame-retardant composite panel body 2 includes an upper metal plate 201, a lower metal plate 202 and a flame-retardant interlayer 203. The bottom of the upper metal plate 201 and the top of the lower metal plate 202 are respectively bonded to the top and bottom of the flame-retardant interlayer 203 by adhesive.
[0037] Specifically, such as Figure 1 , Figure 2 As shown, casters 6 are fixedly connected to the four corners of the bottom of the base 1, and the casters 6 have a braking structure.
[0038] In this embodiment: by setting a flame-retardant composite plate body 2 composed of an upper metal plate 201, a lower metal plate 202 and a flame-retardant interlayer 203, a high flame-retardant effect can be achieved. By setting universal wheels 6, the base 1 can be moved, thereby improving the flexibility of detection.
[0039] Working principle: In use, the flame-retardant composite board body 2 is placed between the first hollow board 301 and the second hollow board 302, and the lower metal plate 202 of the flame-retardant composite board body 2 is tightly attached to the vacuum suction cup 305 at the top of the second hollow board 302. Then, the vacuum pump 303 at the bottom of the second hollow board 302 can be started, so that the vacuum pump 303 draws air from the inside of the second hollow board 302 through the air extraction pipe 304. As the air is drawn out, a negative pressure is formed in the vacuum suction cup 305 connected to the top of the second hollow board 302. Under the action of the external atmospheric pressure, the vacuum suction cup 305 will tightly adhere to the flame-retardant composite board body 2. The vacuum suction cups 305 are numerous and evenly distributed, providing uniform and stable suction force. Then, the hydraulic cylinder 402 is activated, causing its output rod to extend and, through the tension sensor 403 and the cross-shaped fixing bracket 404, drive the first hollow plate 301 downwards, making the vacuum suction cups 305 at the bottom of the first hollow plate 301 tightly adhere to the upper metal plate 201 of the flame-retardant composite panel body 2. Then, the top of the first hollow plate 301 can be activated in the same manner as described above. The vacuum pump 303 in the part causes multiple vacuum suction cups 305 at the bottom of the first hollow plate 301 to firmly adhere and fix the upper metal plate 201 of the flame-retardant composite board body 2. Then, the hydraulic cylinder 402 can be activated, causing the output rod of the hydraulic cylinder 402 to retract and drive the tension sensor 403 to move upward. The tension sensor 403 drives the cross fixing frame 404 to move upward, which in turn drives the first hollow plate 301 to move upward, thereby generating a tension on the upper metal plate 201 of the flame-retardant composite board body 2, so that the upper metal plate 201 of the flame-retardant composite board body 2 adheres to the flame-retardant interlayer 203 and the lower metal plate. Peeling the plate 202 allows for peel strength testing of the flame-retardant composite board body 2. During peeling, the tensile sensor 403 detects the magnitude of the tensile force in real time, converts the tensile force signal into an electrical signal, and transmits the electrical signal to the tensile display 405. The tensile display 405 displays the specific value of the tensile force in real time. Operators can intuitively observe the changes in tensile force during peeling and record relevant data such as the maximum tensile force value for subsequent calculation of the composite board's peel strength. This testing structure is relatively simple and easy to operate, effectively improving testing efficiency.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
