[0047] Example 1

[0048] like Figure 1-13 As shown, an embodiment of the present invention provides a corrugated paper detection device, which includes a detection assembly 300, which includes a C-shaped frame 310, a pressure shoe 320, and two pressure plate modules arranged opposite to each other up and down, one end of the pressure shoe 320 is telescopically arranged on the C-shaped frame 310, any one pressure plate module is connected to the other end of the pressure shoe 320, and the other pressure plate module is arranged on the C-shaped frame 310, so that the two pressure plate modules are close to each other or away from each other;

[0049] Among them, at least one pressure plate module is provided with at least one group of pressure strip groups on the side facing the other pressure plate module, and the pressure strip group includes a plurality of pressure strips 3311 distributed along the circumference of the pressure plate module.

[0050] In this embodiment, the detection component 300 of the corrugated paper detection device includes a C-frame 310, a pressure shoe 320, and two pressure plate modules arranged opposite to each other in an upper and lower direction. The pressure shoe 320 is provided with a center hole, and the area within the center hole is a test area. The C-frame 310 has a top support portion and a bottom support portion arranged opposite to each other in an upper and lower direction. One end of the pressure shoe 320 can be telescopically arranged on the top support portion of the C-frame 310, and any pressure plate module is connected to the other end of the pressure shoe 320. When the pressure shoe 320 is telescopically extended and retracted up and down relative to the top support portion of the C-frame 310, the pressure plate module can be driven to move up and down. The other pressure plate module can be arranged on the bottom support portion of the C-frame 310. Therefore, when the pressure shoe 320 is telescopically extended and retracted up and down relative to the top support portion of the C-frame 310, the two pressure plate modules can be moved closer to each other or farther away from each other to clamp or loosen the cardboard.

[0051] In this embodiment, at least one group of pressure strips arranged along the circumferential direction is provided on the side of at least one pressure plate module facing another pressure plate module, and the pressure strip group specifically includes a plurality of pressure strips 3311 distributed along the circumferential direction of the pressure plate module. Therefore, the detection component 300 of the corrugated paper detection device of this embodiment can ensure the stability of the sample position with as little pressure as possible, and avoid the deformation of the paperboard due to excessive clamping force, which affects the accuracy of the detection data. It can be seen that the corrugated paper detection device of this embodiment ensures the accuracy of the detection data. And it can adapt to paperboards of different thicknesses.

[0052] In some embodiments, the plurality of pressure strips 3311 in the pressure strip group are evenly distributed around the pressure plate module, so that the pressure strip group uniformly clamps the cardboard, thereby preventing the cardboard from being deformed due to excessive local force and affecting the accuracy of the detection data, thereby ensuring the accuracy of the detection data.

[0053] In some embodiments, there are multiple pressure strip groups, and the height of the pressure strips 3311 in the multiple pressure strip groups gradually decreases along the radial inward direction of the pressure plate module to ensure that the periphery of the middle test position remains intact, prevent damage, and improve the detection results.

[0054] In some embodiments, there are multiple groups of pressure strips, and the pressure strips 3311 in the multiple groups of pressure strips are all arc-shaped strips, and the curvature of the pressure strips 3311 in the multiple groups of pressure strips gradually decreases along the radial inward direction of the pressure plate module, which can ensure that the periphery of the middle test position remains intact, prevent damage, and improve the detection results.

[0055] In some embodiments, the pressure plate module includes a pressure plate 331 and a fixed plate 332. The fixed plate 332 in any pressure plate module is connected to the pressure shoe 320, and the fixed plate 332 in the other pressure plate module is connected to the C-frame 310. A pressure plate 331 is floatingly provided on the side where the two fixed plates 332 are close to each other. At least one pressure plate 331 is provided with at least one group of limiting grooves arranged along the circumferential direction. The limiting grooves 3312 in the limiting groove group are all penetrated by locking teeth 333. A push rod 334 is provided between the pressure plate 331 with the limiting groove group and the corresponding fixed plate 332. One end of the push rod 334 is hinged to the pressure plate 331, and the other end is slidably connected to the fixed plate 332 in the radial direction. The locking teeth 333 abut against the push rod 334.

[0056] In the present embodiment, the pressure plate module comprises a pressure plate 331 and a fixed plate 332, that is, both pressure plate modules comprise a pressure plate 331 and a fixed plate 332, the fixed plate 332 in any pressure plate module is connected to the pressure shoe 320, and the fixed plate 332 in the other pressure plate module is connected to the C-shaped frame 310, when the pressure shoe 320 is extended and retracted up and down relative to the top support portion of the C-shaped frame 310, the fixed plate 332 can be driven to move up and down, so that the two fixed plates 332 are close to each other or away from each other, because the pressure plate 331 is provided on both sides of the two fixed plates 332 that are close to each other so as to float, when the two fixed plates 332 are close to each other, the fixed plates 332 and their corresponding pressure plates 331 can be made close to each other, and in the present embodiment, at least one group of limiting grooves arranged along the circumferential direction is provided on at least one pressure plate 331, The limiting grooves 3312 in the brackets are all provided with locking teeth 333, and a push rod 334 is provided between the pressure plate 331 with the limiting groove group and the corresponding fixed plate 332. One end of the push rod 334 is hinged to the pressure plate 331, and the other end of the push rod 334 is slidably connected to the fixed plate 332 along the radial direction. When the fixed plate 332 and the corresponding pressure plate 331 approach each other, the other end of the push rod 334 can slide radially along the fixed plate 332, so that the inclination angle of the push rod 334 is reduced. Since the locking teeth 333 abut against the push rod 334, when the inclination angle of the push rod 334 is reduced, the locking teeth 333 can move from the limiting groove 3312 to the pressure plate 331 away from the push rod 334. Therefore, when clamping, the cardboard is supported by the locking teeth 333, making it more difficult for the cardboard to move, thereby further improving the accuracy of the detection result.

[0057] In some embodiments, the limiting grooves 3312 in the limiting groove group are evenly distributed in the circumferential direction of the pressure plate 331, so that the locking teeth 333 are evenly distributed in the circumferential direction of the pressure plate 331, so that the cardboard is evenly stressed, thereby preventing the cardboard from being deformed due to excessive local stress and affecting the accuracy of the detection data, thereby ensuring the accuracy of the detection data.

[0058] In some embodiments, the locking tooth 333 and the push rod 334 are magnetically attracted to ensure that the locking tooth 333 and the push rod 334 are against each other.

[0059] In some embodiments, the limiting groove group is a plurality of groups; the height of the locking teeth 333 in the plurality of limiting groove groups gradually decreases along the radial inward direction of the pressure plate 331, which can ensure that the periphery of the middle test position remains intact, prevent damage, and improve the detection results.

[0060] Specifically, the plurality of groups of limit groove groups have a plurality of locking teeth 333 arranged in sequence along the radially inward direction of the pressure plate 331, and the plurality of locking teeth 333 arranged in sequence along the radially inward direction of the pressure plate 331 are distributed in the circumferential direction of the pressure plate 331, preferably evenly distributed, the length direction of the push rod 334 is parallel to the radial direction of the pressure plate 331, and a plurality of push rods 334 are distributed in the circumferential direction of the pressure plate 331, and in the radially inward direction of the pressure plate 331, one end of the push rod 334 is located on the inner side of the other end of the push rod 334, and the plurality of locking teeth 333 arranged in sequence along the radially inward direction of the pressure plate 331 are in one-to-one correspondence with the plurality of push rods 334, that is, a group of locking teeth 333 arranged in sequence along the radially inward direction of the pressure plate 331 is in contact with the plurality of push rods 334. The plurality of locking teeth 333 arranged in sequence along the radial direction of the pressure plate 331 abut against a push rod 334. When the inclination angle of the push rod 334 is reduced, the plurality of locking teeth 333 arranged in sequence along the radial direction of the pressure plate 331 can move from the corresponding limiting grooves 3312 toward the pressure plate 331 away from the push rod 334. Therefore, during clamping, the cardboard is supported by the plurality of corresponding locking teeth 333, making it more difficult for the cardboard to move, thereby further improving the accuracy of the detection result. At the same time, the height of the plurality of locking teeth 333 arranged in sequence along the radial direction of the pressure plate 331 gradually decreases along the radial direction of the pressure plate 331, thereby preventing the cardboard from being deformed due to excessive local force and affecting the accuracy of the detection data, thereby ensuring the accuracy of the detection data.

[0061] In some embodiments, the limiting groove group is a plurality of groups; the plurality of limiting grooves 3312 in a radially outer group of limiting grooves are circumferentially connected, so that the plurality of locking teeth 333 in a radially outer group of limiting grooves are combined to form cutting ring teeth.

[0062] In the prior art, the tear resistance test device is usually used to manually push the cardboard to the detection area of ​​the tear resistance test device. Multiple samples need to be tested in the same batch, and the samples also need to be saved after the test is completed. The staff will cut the cardboard in advance or cut it after the test is completed, which is cumbersome.

[0063] This embodiment can cut by cutting the ring teeth to achieve automatic cutting, while reducing the work intensity of the staff, improving the degree of automation and improving work efficiency.

[0064] In some embodiments, an elastic member 335 is clamped between the pressure plate 331 and the fixed plate 332. The elastic member 335 may be a disc spring. The elastic member 335 may automatically withdraw the locking teeth 333 after automatic cutting and sample testing are completed, which is easy to operate and reduces labor.

[0065] In some embodiments, the side of the locking tooth 333 facing the radially outer side of the pressure plate 331 is a first arc surface 3331, and the side of the limiting groove 3312 facing the first arc surface 3331 is constructed as a guide arc surface that is compatible with the first arc surface 3331. The movement of the locking tooth 333 can be guided by the first arc surface 3331 and the guide arc surface to ensure the moving direction of the locking tooth 333.

[0066] A surface of the locking tooth 333 that is away from the first arc surface 3331 is a matching plane 3333 , which can guide the movement of the locking tooth 333 together with the matching plane.

[0067] In some embodiments, a second arc surface 3332 is constructed on one side of the locking tooth 333 away from the corresponding push rod 334 and toward the radially outer side of the pressure plate 331 to form an extrusion spike portion. The extrusion spike portion facilitates the insertion of the locking tooth 333, and the side opposite to the second arc surface 3332 squeezes the cardboard, making the cardboard more solid and less likely to move, thereby further improving the accuracy of the detection result.

[0068] In some embodiments, the detection component 300 also includes an annular shell 336, which is sleeved on the outer periphery of the pressure plate 331 and connected to the fixed plate 332 corresponding to the pressure plate 331. The annular shell 336 is provided with an avoidance groove 3361 extending radially, and the side wall of the avoidance groove 3361 is provided with a slide groove 3362 extending radially. The other end of the push rod 334 is structured to be inserted into a pin shaft in the slide groove 3362, so that the other end of the push rod 334 can slide radially along the fixed plate 332.

[0069] In some embodiments, a lug 3313 is configured on one side of the pressure plate 331 facing the corresponding fixed plate 332 , and one end of the push rod 334 is configured with an insertion hole for the lug 3313 to be inserted, so that one end of the push rod 334 is hinged to the pressure plate 331 .

[0070] In some embodiments, the pressure strip group is arranged on the pressure plate 331. When a limiting groove group is opened on the pressure plate 331, the limiting groove group is located radially outside the pressure strip group, which can ensure that the periphery of the middle test position remains intact, prevent damage, and improve the detection results.

[0071] In some embodiments, the corrugated paper detection device also includes a base 100, a control panel 200 and a telescopic assembly. The C-frame 310 is disposed on the base 100, and both ends of the telescopic assembly are respectively connected to one end of the pressure shoe 320 and the C-frame 310 to drive the pressure shoe 320 to move.

[0072] Working process:

[0073] When the device is working, the corrugated paper or other cardboard to be tested is placed on the pressure plate 331, and then after the instrument data is set, the test is started, and the pressure shoe 320 moves slowly downward until the two pressure plates 331 clamp the upper and lower surfaces of the corrugated paper at the same time. During the above process, the fixed plate 332 that is not connected to the pressure shoe 320 is always in the initial state.

[0074] Then the pressure shoe 320 continues to move downward, the elastic member 335 is compressed under the pressure, and the two pressure plates 331 approach each other. At this time, the inclination angle of the push rod 334 becomes smaller and more horizontal, and the locking tooth 333 is pressed by the upper surface of the push rod 334, so that the locking tooth 333 extends out and inserts into the corrugated paper. As the pressure shoe 320 continues to move downward, the locking tooth 333 inserts deeper and deeper into the corrugated paper, and the extrusion spike portion formed by the second arc surface 3332 of the locking tooth 333 squeezes the paperboard, making the paperboard more solid.

[0075] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
