Description

Technical Field

[0002] Corrugated cardboard is a multi-layer adhesive body consisting of at least one layer of corrugated core paper and one layer of cardboard. It usually has high mechanical strength and can withstand collisions and falls during transportation. In the prior art, after the corrugated cardboard is pressed and formed, it is usually necessary to test its mechanical properties such as puncture resistance, tensile strength and edge compression resistance to ensure the quality of the corrugated cardboard forming.

[0003] However, the traditional method of testing the mechanical properties of corrugated cardboard has the following problems: 1. When the prior art tests the mechanical properties of formed corrugated cardboard such as puncture resistance, tensile strength and edge compression resistance, the equipment required for each test is different, resulting in a large number of equipment required for testing multiple mechanical properties of formed corrugated cardboard and each device needs to be operated separately, which leads to a large space occupied by the overall testing equipment, high overall space cost and equipment maintenance cost, and the overall steps of operating multiple devices separately are cumbersome and the testing efficiency is low; 2. When the prior art uses the testing equipment to test the mechanical properties of corrugated cardboard samples, it is usually necessary to manually limit the loading and unloading of the corrugated cardboard samples and subsequently clean and unload the damaged corrugated cardboard samples.

[0038] Step 1: Raw materials and equipment: prepare surface paper as the outer and inner layers of the corrugated board, and prepare core paper for making the corrugated structure.

[0039] Step 2: Corrugated board forming: First, the heated core paper is pressed into a corrugated shape by a corrugated roller, and then both sides of the core paper are glued to the top paper by glue to form a double-sided corrugated board.

[0040] Step 3: Performance testing: Cut the formed corrugated cardboard into samples required for testing. The sample sizes corresponding to different mechanical properties are different. The corresponding samples are subjected to mechanical testing through testing equipment.

[0041] Step 4: Transportation and storage: After all mechanical properties tests of the corrugated cardboard samples are qualified, the pressed corrugated cardboards are stacked and transported to a dry and well-ventilated warehouse for storage.

[0042] See also Figure 2 and Figure 3 In the above step three, a plurality of mechanical properties of the pressed corrugated cardboard are tested by a testing device, wherein the testing device comprises a testing platform 1, and a bursting mechanism 2, a stretching mechanism 3 and an edge pressing mechanism 4 are arranged on the upper side of the testing platform 1 from left to right in sequence, and a driving mechanism 5 for driving the bursting mechanism 2, the stretching mechanism 3 and the edge pressing mechanism 4 is also arranged on the testing platform 1.

[0043] See also Figure 2 and Figure 3 The breakage-resistant mechanism 2 includes a support platform 21 and a support platform 23 fixedly arranged on the upper side of the detection platform 1. A feeding component 22 is arranged on the upper side of the support platform 21, a hole slot 1 is opened on the support platform 23, and a detection component 24 is arranged above the support platform 23.

[0044] See also Figure 4 The loading component 22 includes a limit frame 221 that moves forward and backward, a rotating plate 222 is rotatably arranged at the lower side of the limit frame 221, the right end of the limit frame 221 is hinged to the right end of the rotating plate 222 below, and a hole groove 2 that passes through the upper and lower parts is opened on the rotating plate 222.

[0045] See also Figure 4 The detection component 24 includes a downwardly movable downwardly movable lower rod 241, a cone head 242 is fixedly provided at the lower end of the downwardly movable cylinder, a pressure sensor 1 is installed in the cone head 242, an elastic cover 243 is elastically slidably provided on the outer side of the cone head 242, a positioning plate 244 is fixedly provided on the lower side of the elastic cover 243, and a hole slot 3 is opened on the positioning plate 244 for the cone head 242 to pass through.

[0046] When the puncture resistance of the formed corrugated cardboard is to be tested, under the drive of the driving mechanism 5, the limit frame 221 is first aligned with the lower end of the discharge box 225, and the sample 226 at the lower side of the discharge box 225 then falls stably into the limit frame 221 under the action of gravity and fits with the upper surface of the rotating plate 222. At this time, the support platform 21 can limit the lower surface of the rotating plate 222 to prevent the rotating plate 222 from flipping downward, and then the flat support plate 223 is moved to the left to fit the lower surface of the rotating plate 222 and also limit the rotating plate 222, and then the limit frame 221 and the rotating plate 222 drive the internal sample 226 to move backward synchronously, the flat support plate 223 moves backward synchronously and always limits the rotating plate 222, and the blocking plate 224 also moves backward synchronously and performs The blocking limit is used to prevent the sample 226 from sliding down from the discharge box 225. As the limit frame 221 and the rotating plate 222 continue to move backward until the hole slot 2 on the rotating plate 222 is aligned with the hole slot 1 on the support 23 and the hole slot 3 on the positioning plate 244, the lower pressure rod 241 drives the cone head 242 and the elastic cover 243 to move downward synchronously, and the positioning plate 244 presses the upper surface of the sample 226 positioned in the limit frame 221. As the lower pressure rod 241 continues to move downward, the cone head 242 extends downward from the hole slot 3 and applies downward pressure to the upper surface of the sample 226 until the cone head 242 completely punctures the sample 226, so that the puncture resistance of the sample 226 can be obtained through the pressure sensor 1 installed in the cone head 242, wherein the hole slot 1 and the hole slot 2 can allow the cone head 242 to pass through to avoid damage to the cone head 242.

[0047] When the damaged sample 226 is to be unloaded, the driving mechanism 5 drives the rotating plate 222 to move forward until it is separated from the support platform 23. At this time, the flat supporting plate 223 is moved to the right to release the limit of the rotating plate 222, and the rotating plate 222 is rotated downward to make the sample 226 inside the limit frame 221 automatically fall down under the action of gravity. When the unloading of the sample 226 is completed, the flat supporting plate 223 is moved to the left again and gradually contacts the lower surface of the rotating plate 222 until the rotating plate 222 is driven to rotate upward again and reset to a horizontal state, and finally the limit frame 221 and the rotating plate 222 are moved forward and reset to the upper side of the support platform 21. At this time, the limit frame 221 is aligned with the lower end of the unloading box 225 again, and the sample 226 at the bottom of the unloading box 225 can then fall stably into the limit frame 221 under the action of gravity and fit the upper surface of the rotating plate 222.

[0052] When the tensile strength of the formed corrugated cardboard is to be tested, the collecting box 321 is first moved to the upper side of the bottom plate 31 under the drive of the driving mechanism 5, and the through slot inside the collecting box 321 is aligned with the unloading port 1 of the unloading box 2 326, and the leftmost sample 2 327 in the unloading box 2 326 then falls into the collecting box 321 and is supported by the bottom plate 31 below it, while the remaining sample 2 327 in the unloading box 2 326 will synchronously slide to the left along the inclined surface at the bottom of the unloading box 2 326 to fill the position, and then the connecting plate 1 325 passes through the rod The second component drives the clamping plate 1 324 to move leftward until the lower end of the sample 2 327 in the material collection box 321 is clamped and fixed, and the L-shaped bracket 351 synchronously drives the wedge block 1 352 to move a certain distance to the left and aligns the inclined surface of the rear end of the wedge block 1 352 with the inclined surface of the front end of the wedge block 2 354, and then the material collection box 321 drives the sample 2 327 inside it to move backward to between the clamping plate 2 343 and the clamping plate 345, and the L-shaped baffle plate 322 synchronously moves backward and enters the discharge port 1 on the discharge box 2 326 The wedge block 1 352 also moves backward synchronously, and drives the limit table 355 and the clamping plate 345 to move synchronously to the left along the guide rail 344 through the pressure cooperation with the wedge block 2 354, so that the upper end of the sample 2 327 in the collecting box 321 is clamped and fixed when it moves between the clamping plate 2 343 and the clamping plate 345. At this time, the rack 2 349 moves downward and meshes with the gear 348, and the gear 348 also meshes with the rack 1 347 at the same time, and the rack 1 347 drives the clamping plate 347 to move to the left. The holding platform 342 moves upward along the guide rod 341 and applies an upward pulling force to the clamped sample 2 327 through the clamping plate 2 343 and the clamping plate 345 until the sample 2 327 is completely broken, so that the tensile strength of the sample 2 327 can be obtained through the pressure sensor 2 installed in the clamping platform 342, wherein when the clamping plate 345 moves upward, the T-shaped slide column 346 moves upward along the linear groove 356 synchronously therewith, and the clamping plate 345 can reduce the friction resistance between it and the limit platform 355 through the ball bearing.

[0053] When the damaged sample 2 327 is to be unloaded, the collecting box 321 is moved forward, and the wedge block 1 352 is separated from the wedge block 2 354. The limit table 355 is moved to the right and reset under the action of the spring rod 1 353, and the T-shaped slide column 346 and the clamping plate 345 are simultaneously driven to move to the right along the guide rail 344 to release the clamping of the upper half of the damaged sample 2 327, so that the part automatically falls down and unloads. Then, the clamping plate 1 324 is moved to the right to release the clamping of the lower half of the damaged sample 2 327 in the collecting box 321, so that the part automatically slides down from the lower end of the collecting box 321 to unload. When the unloading of the sample 2 327 is completed, the collecting box 321 is moved forward again until it is aligned with the unloading port 1, and the unloading box 2 3 The leftmost sample 2327 in 26 then falls into the collecting box 321. Since the clamping plate 1 324 and the flat support plate 1 223 move synchronously, and the flat support plate 1 223 needs to move to the left again before the rotating plate 222 moves forward and resets to the upper side of the support platform 21 to press and reset the downward-turned rotating plate 222, the clamping plate 1 324 is now at the leftmost end and is located in the collecting box 321. Finally, after the rotating plate 222 in the horizontal state is reset to the upper side of the support platform 21, the flat support plate 223 and the clamping plate 1 324 move to the right synchronously, thereby moving the clamping plate 1 324 out of the collecting box 321. At this time, the sample 2 327 that has fallen into the collecting box 321 continues to fall until it is supported by the bottom plate 31 on its lower side.

The right side of the material discharge box 3 416 is fixedly connected to the testing platform 1 via a connecting frame 4. The bottom of the inner surface of the material discharge box 3 416 is an inclined surface and a material discharge port 2 on the material discharge box 3 416 is located at the lower end of the inclined surface.

A plate 3 is symmetrically fixedly arranged on the lower side of the material discharge box 3 416 and on the left and right sides of the material discharge port 2.

[0056] See also Figure 8 and Fig. 9 The limiting assembly 42 includes a fixed platform 421 fixedly arranged on the upper side of the detection platform 1 and located on the right side of the U-shaped frame 411, and a spring rod 3 422 is elastically slidably arranged on the fixed platform 421 in a front-to-back symmetrical manner. The right ends of the front-to-back symmetrical spring rods 422 are jointly fixed with an L-shaped support plate 423 located on the lower side of the U-shaped frame 411. The rear end of the horizontal section of the L-shaped support plate 423 is an inclined surface. A side baffle plate 424 that can move left and right is arranged on the right side of the L-shaped support plate 423 and the U-shaped frame 411. A flat support plate 425 located below the U-shaped frame 411 is fixedly arranged on the left side of the side baffle plate 424.

[0057] When the edge compression resistance of the formed corrugated paperboard is to be tested, the U-shaped frame 2 411 is first moved to the upper side of the horizontal section of the L-shaped support plate 423 under the drive of the driving mechanism 5, and the U-shaped frame 2 411 is aligned with the unloading port 2 of the unloading box 3 416, and the leftmost sample 3 417 in the unloading box 3 416 then falls to the inner side of the U-shaped frame 2 411 and is supported by the L-shaped support plate 423 on the lower side thereof, while the remaining sample 3 417 in the unloading box 3 416 will The inclined surface of the bottom of the material box 3 416 is synchronously slid to the left to fill the position, and then the side baffle 2 424 is moved to the left to fit the sample 3 417 inside the U-shaped frame 2 411, and the side baffle 2 424 and the side baffle 1 414 are only used to limit the left and right positions of the sample 3 417 instead of tightly fitting and clamping, so as to avoid the clamping force of the side baffle 2 424 and the side baffle 1 414 on the sample 3 417 affecting the final test result of the edge compression resistance of the sample 3 417. The flat pallet 2 425 then moves synchronously to the left and pushes the L-shaped pallet 423 to the left until the flat pallet 2 425 replaces the L-shaped pallet 423 to support the sample 3 417, and then the U-shaped frame 2 411 and the flat pallet 2 425 drive the sample 3 417 to move backward synchronously until the sample 3 417 is directly below the pressure plate 43, and the baffle plate 2 415 then closes the discharge port 2 through the horizontal plate on the front side. At this time, the pressure plate 43 moves downward to apply downward pressure to the upper edge of the sample 3 417 until the upper edge of the sample 3 417 is obviously deformed, so that the edge compression resistance of the sample 3 417 can be obtained through the pressure sensor 3 installed in the pressure plate 43, wherein the side baffle plate 1 414 can be displaced to the left through the spring rod 3 422 to avoid hindering the compressive deformation of the sample 3 417, thereby ensuring the accuracy of the edge compression resistance test results of the sample 3 417.

[0058] When the damaged sample 3 417 is to be unloaded, the side baffle 2 424 and the flat support plate 2 425 are moved to the right synchronously until the flat support plate 2 425 no longer supports the sample 3 417, and the sample 3 417 automatically falls down and unloads; when the unloading of the sample 3 417 is completed, the U-shaped frame 2 411 and the side baffle 2 424 are moved forward again to reset, and since the side baffle 2 424 and the flat support plate 2 425 also move synchronously with the flat support plate 1 223, the flat support plate 2 425 is also at the leftmost end at this time. At this time, the L-shaped support plate 423 is reset to the rightmost end under the action of the spring rod three 422, and the flat support plate two 425 moving forward cooperates with the inclined surface at the rear end of the horizontal section of the L-shaped support plate 423, so that the L-shaped support plate 423 moves to the left again, and finally the flat support plate one 223 and the flat support plate two 425 move to the right synchronously. At this time, the U-shaped frame two 411 is aligned with the discharge port two, and the sample three 417 on the far left in the discharge box three 416 falls to the inside of the U-shaped frame two 411 and is supported by the L-shaped support plate 423.
