Description

Technical Field

[0001] The invention relates to the technical field of strength detection devices, in particular to a corrugated paper performance strength detection bearing device. Background Art

[0002] During the production of corrugated paper, strength testing is usually carried out by sampling testing. This testing method involves randomly selecting a portion of samples from the overall product for testing, and evaluating the quality of the overall product by analyzing the performance of these samples.

[0003] When the existing technology performs strength testing on corrugated paper, the corrugated paper is usually placed on a flat table, clamped and fixed by a clamp, and the surface of the corrugated paper is squeezed with a punch plate or a pressure head until the corrugated paper is damaged, so as to test the performance strength of the corrugated paper. In this process, because the sampling test in the production process needs to test a certain amount of corrugated paper, the corrugated paper is placed one by one by hand, and then fixed by a clamp. After the test is completed, the corrugated paper is removed and replaced with a new one. This method is inefficient for corrugated paper testing and requires more manpower. Summary of the invention

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention pushes the connecting frame to move upward through the extended end of the fourth electric push rod, and the insertion rod passes through the insertion rod of the bottom connecting plate, and then the connecting frame is driven to slide to both sides along the cross bar through the two-way electric push rod, and the limit plate is pulled out from the inside of the side plate through the connection of the insertion rod and the connecting plate. At this time, the corrugated paper at the bottom falls on the placement plane without being blocked by the limit plate.

In the same way, when the fourth electric push rod drives the insertion rod to continue to move upward, the upper limit plate can be pulled out in turn, and the corresponding corrugated cardboard falls on the placement plane, thereby ensuring the delivery of a single corrugated paper without confusion.

[0017] 2.

At the same time, when the third electric push rod drives the placement component to move upward as a whole, the bottom plate of the fourth electric push rod slides along the first slide groove to maintain synchronous rise. The setting of the position of the connecting frame and the cross bar can avoid affecting the rotational connection between the mounting frame and the tripod.

[0018] 3. The present invention can push the entire placement assembly and the unlocking assembly to move upward or downward through the third electric push rod. The upward movement can provide space for the rotation of the tripod to avoid movement interference. When moving downward, the outlet of the placement assembly can be close to the placement plane, which is convenient for the transportation of corrugated paper. After unlocking the fixed plate and the side plate at one end, the baffle and the corner frame can be pulled out, and the corrugated paperboard can be refilled from the opening position to the position where the limit plate is installed inside to detect the next group of corrugated paperboards.

[0019] 4. The present invention slides the moving block along the moving groove to adjust the position of the horizontal plate, and adjusts the position of the clamp on the horizontal plate through the buckle frame to be consistent with the position of the four right-angle frames of the placement component. The position is locked by the locking bolt, and the various structures of the placement component can be fixed by bolts, so that it is suitable for the detection of corrugated cardboards of different sizes.

[0020] 5. Compared with the prior art, the present invention uses the three placement planes of the tripod to alternately receive corrugated paper, detect the strength of corrugated paper and send out corrugated paper, thereby improving the overall detection efficiency. The placement component and the unlocking component can cooperate to alternately send the pre-stored corrugated paper to the placement plane, and cooperate with the clamp on the placement plane to clamp and fix the corrugated paper and send it for detection, reducing the time spent on manual operation.

When the device is used, the corrugated cardboard 7 to be detected is placed equidistantly inside the placement component 5, and the motor 12 at the outer end of the mounting frame 11 drives the triangle platform 2 to rotate. When the placement plane 21 of the triangle platform 2 corresponds to the bottom outlet of the placement component 5, the unlocking component 6 sends out the corrugated cardboard 7 of the bottom layer, and the corrugated cardboard 7 is fixed by the clamp 25 on the placement plane 21. Then the triangle platform 2 rotates to the detection position, and the surface of the corrugated cardboard 7 is squeezed by the squeezing component 4 to detect its strength. At the same time, another group of placement planes 21 correspond to the outlet of the placement component 5 again, and the corrugated cardboard 7 is continuously conveyed. The corrugated cardboard 7 after the detection is sent out through one side of the conveyor belt 3. The three groups of placement planes 21 alternately receive the corrugated cardboard 7, detect and send it out.

[0031] In this embodiment, the triangular table 2 is provided with moving grooves 22 on both sides corresponding to each placement plane 21, and moving blocks 23 are slidably connected to the two ends of the moving grooves 22, and horizontal plates 24 are provided at both ends of the placement plane 21, and the two ends of the horizontal plate 24 are fixedly connected to the moving blocks 23, and the clamp 25 includes a lower clamping plate 251, a buckle frame 257 is fixed on one side of the lower clamping plate 251, and the buckle frame 257 is slidably sleeved on the surface of the horizontal plate 24, and a locking bolt 258 is inserted at the upper end of the buckle frame 257, a sliding column 253 is fixed at the right angle end of the lower clamping plate 251, and an upper clamping plate 252 is slidably sleeved on the surface of the sliding column 253, a motor 254 is fixed on the top of the sliding column 253, and a rotating plate 255 is fixed to the output end of the motor 254, a micro-electric push rod 256 is fixed on the outer end surface of the rotating plate 255, and the micro-electric push rod 256 is fixed on the outer end surface of the rotating plate 255. The extended end of the push rod 256 is fixedly connected to the upper clamping plate 252, and the moving block 23 is slid along the moving groove 22 to adjust the position of the cross plate 24. The position of the clamp 25 is adjusted on the cross plate 24 by the buckle frame 257 to be consistent with the position of the four right-angle frames 55 of the placement component 5, and the position is locked by the locking bolt 258. The various structures of the placement component 5 can be fixed by bolts, so that it is suitable for the detection and use of corrugated cardboard 7 of different sizes. Before the corrugated cardboard 7 is placed, the motor 254 drives the upper clamping plate 252 to rotate to the outside through the rotating plate 255. After the corrugated cardboard 7 is placed on the lower clamping plate 251, the height of the upper clamping plate 252 is adjusted by the micro-electric push rod 256, and then it is turned back by the motor 254 to press it on the top of the corrugated cardboard 7 to fix its four corners. The outward rotation of the upper clamping plate 252 is also used to send the corrugated cardboard 7 out.

[0032] In this embodiment, the extrusion assembly 4 also includes a slide rail 41, and the base 1 is located on the back of the slide frame 42 and is fixed with two slide rails 41, and the slide rails 41 are parallel to the placement plane 21 and the slide frame 42, and the back of the slide frame 42 is slidably sleeved on the slide rail 41, and the interior of the slide frame 42 is installed with a first electric push rod 43 through a slide seat and a driving screw rod, and the extended end of the first electric push rod 43 is fixedly connected to the spherical pressure head 44, and the base 1 is located between the two slide rails 41 and is rotatably connected to a second electric push rod 45 through a rotating shaft, and the extended end of the second electric push rod 45 is rotatably connected to the slide frame 42 through a rotating shaft, and the driving screw rod inside the slide frame 42 is composed of a screw rod and a driving device, which is a common translation device, so it is not shown in the figure, through the second electric push rod The push rod 45 pushes the slide frame 42 to slide along the slide rail 41, so as to adjust the position of the spherical pressure head 44. The first electric push rod 43 is moved along the inside of the horizontal frame to adjust the horizontal position of the spherical pressure head 44, so as to perform multi-point strength detection on the corrugated cardboard 7 through the spherical pressure head 44. The first electric push rod 43 drives the spherical pressure head 44 to approach or move away from the placement plane 21, so as to facilitate the compression strength detection of the corrugated cardboard 7 on the placement plane 21, and at the same time, it can also avoid interfering with the rotation of the tripod 2 when moving away. The specific strength detection method can refer to the existing technology. A pressure sensor is set on the spherical pressure head 44. By observing the condition of the corrugated cardboard 7, when the corrugated cardboard 7 is damaged, the current pressure value is recorded, so as to obtain the strength of the corrugated cardboard 7.

[0033] In this embodiment, the placement component 5 also includes a third electric push rod 51. The third electric push rod 51 is fixed on the top of the mounting frame 11, and a fixing plate 52 is fixed on the extended end of the third electric push rod 51. The two ends of the fixing plate 52 are fixedly connected to the side plates 53 by bolts. The third electric push rod 51 can push the entire placement component 5 and the unlocking component 6 to move upward or downward. The upward movement can provide space for the rotation of the tripod 2 to avoid movement interference. When moving downward, the outlet of the placement component 5 can be brought close to the placement plane 21 to facilitate the transportation of corrugated paper. After unlocking the fixing plate 52 at one end from the side plate 53, the baffle 54 and the corner frame can be pulled out, and the corrugated cardboard 7 can be refilled from the opening position to the position where the limit plate 611 is installed internally to perform the next group of corrugated cardboard 7 detection.

[0034] In this embodiment, the unlocking component 6 also includes a first slide groove 63, and the first slide groove 63 is opened on both sides of the mounting frame 11, and the outer end of the first slide groove 63 is slidably installed with a bottom plate 62, and a fourth electric push rod 61 is fixed on the top of the bottom plate 62, and the extended end of the fourth electric push rod 61 is connected to a connecting frame 64, and a cross bar 66 is slidably inserted between the two groups of the connecting frames 64, and a bidirectional electric push rod 67 is fixed on the top of the cross bar 66, and the extended end of the bidirectional electric push rod 67 is fixedly connected to the two connecting frames 64, and a second slide groove 65 is opened at the part where the connecting frame 64 is connected to the fourth electric push rod 61, and the second slide groove 65 is slidably connected inside. The fourth electric push rod 61 is connected to a block, and the extended end of the fourth electric push rod 61 is fixedly connected to the block in the second slide groove 65. The two ends of the connecting plate 69 are provided with plug holes 610. The connecting frame 64 is fixed with an insertion rod 68 at the position corresponding to the insertion hole 610, and the insertion rod 68 can be inserted into the inside of the insertion hole 610. The limiting plate 611 is inserted into the inside of the side plate 53 to play a role in limiting the corrugated paper placed at equal distances, so as to avoid the remaining corrugated paper from falling when a single corrugated paper is sent out from the bottom. The corrugated paper at the bottom is sent out first. When the placement plane 21 rotates to correspond to the outlet of the placement component 5, the extended end of the fourth electric push rod 61 pushes the connecting frame 64 to move upward, and the insertion rod 68 passes through the insertion rod 68 of the bottom connecting plate 69, and then the connecting frame 64 is driven to slide to both sides along the cross bar 66 through the bidirectional electric push rod 67. The limit plate 611 is pulled out from the inside of the side plate 53 through the insertion of the insertion rod 68 and the connecting plate 69. At this time, the corrugated paper at the bottom falls on the placement plane 21 without the obstruction of the limit plate 611. Because the position of the clamp 25 in the placement plane 21 and the right-angle frame 55 have been adjusted in advance, the corrugated paper will directly fall into the clamp 25 of the placement plane 21, and the four corners of the corrugated paperboard 7 are clamped and fixed by the clamp 25. In the same way, the fourth electric push rod 61 drives the insertion rod 68 to continue to move forward When moving upward, the upper limit plate 611 can be pulled out in turn, and the corresponding corrugated cardboard 7 falls on the placement plane 21, thereby ensuring the delivery of a single corrugated cardboard without confusion. Here, first, when the bidirectional electric push rod 67 pushes the connecting frame 64 to move, the extended end of the fourth electric push rod 61 slides along the inside of the second slide groove 65 to maintain the connection with the connecting frame 64. At the same time, when the third electric push rod 51 drives the placement component 5 to move upward as a whole, the bottom plate 62 at the bottom of the fourth electric push rod 61 slides along the first slide groove 63 to maintain synchronous ascent. The setting of the position of the connecting frame 64 and the cross bar 66 can avoid affecting the rotational connection between the mounting frame 11 and the tripod 2.

[0035] When using the device, the corrugated cardboard 7 to be detected is placed equidistantly inside the placement component 5, the moving block 23 is slid along the moving groove 22, the position of the cross plate 24 is adjusted, and the position of the clamp 25 is adjusted on the cross plate 24 by the buckle frame 257 to be consistent with the position of the four right-angle frames 55 of the placement component 5, and the position is locked by the locking bolt 258. The various structures of the placement component 5 can be fixed by bolts, so that it is suitable for the detection of corrugated cardboards 7 of different sizes. The motor 12 at the outer end of the mounting frame 11 drives the triangular table 2 to rotate. When the placement plane 21 of the triangular table 2 corresponds to the bottom outlet of the placement component 5, the corrugated cardboard 7 is placed. Before the placement, the motor 254 drives the upper clamping plate 252 to rotate to the outside through the rotating plate 255, and the corrugated paper starts to be sent out from the bottom. When the placement plane 21 rotates to correspond to the outlet of the placement component 5, the extended end of the fourth electric push rod 61 pushes the connecting frame 64 to move upward, and the insertion rod 68 passes through the insertion rod 68 of the bottom connecting plate 69, and then the connecting frame 64 is driven to slide to both sides along the cross bar 66 through the bidirectional electric push rod 67. Through the insertion of the insertion rod 68 and the connecting plate 69, the limit plate 611 is pulled out from the inside of the side plate 53. At this time, the corrugated paper at the bottom falls on the placement plane 21 without the obstruction of the limit plate 611, and the corrugated paper board 7 is placed on the placement plane 21. After being placed on the lower clamping plate 251, the height of the upper clamping plate 252 is adjusted by the micro electric push rod 256, and then the motor 254 is used to turn it back and press it on the top of the corrugated cardboard 7 to fix its four corners. Then the tripod 2 is rotated to the detection position, and the second electric push rod 45 pushes the slide frame 42 to slide along the slide rail 41 to adjust the position of the spherical pressure head 44. The first electric push rod 43 is moved along the inside of the horizontal frame to adjust the horizontal position of the spherical pressure head 44, and then the corrugated cardboard 7 can be tested for strength at multiple points by the spherical pressure head 44. The first electric push rod 43 drives the spherical pressure head 44 to approach or move away from the placement plane 21. It is convenient to test the extrusion strength of the corrugated cardboard 7 on the placement plane 21, and at the same time, it can also avoid interfering with the rotation of the tripod 2 when it is far away. The specific strength detection method can refer to the existing technology. A pressure sensor is set on the spherical pressure head 44. By observing the condition of the corrugated cardboard 7, when the corrugated cardboard 7 is damaged, the current pressure value is recorded to obtain the strength of the corrugated cardboard 7. At the same time, another group of placement planes 21 is re-aligned with the outlet of the placement component 5 to continue to transport the corrugated cardboard 7. The corrugated cardboard 7 after the test is sent out through one side of the conveyor belt 3. The three groups of placement planes 21 alternately receive the corrugated cardboard 7, test and send it out.
