These improvements include aspects such as environmental friendliness, moisture resistance, and fire resistance.

[0004] During the improvement process of corrugated cardboard, the finished corrugated cardboard needs to undergo compressive strength testing.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4The environmentally friendly, moisture-proof, and fire-resistant corrugated cardboard compressive strength testing device shown includes a skid-mounted base 100, a motor mounting platform 101, a PLC controller 102, a horizontal platform 103, and corrugated cardboard 120.

[0026] A power motor 105 is installed on the motor mounting platform 101.

[0027] A coupling 106 is installed on the power motor 105.

[0028] A sliding groove 109 is provided on one side of the horizontal plate 103.

[0029] A slider 110 is provided inside the slide groove 109.

[0030] The upper part of the slider 110 is provided with a slider threaded hole 111.

[0031] A lead screw 108, which is connected to the coupling 106, is installed inside the slider 110 through the slider threaded hole 111.

[0032] A horizontal plate 112 is provided on the upper end face of the slider 110.

[0033] Several transition plates 113 are evenly distributed on one side of the horizontal plate 112.

[0034] One side of the transition plate 113 is provided with a pressure application part 115.

[0035] A horizontal bearing plate 116 is provided on one end face of the horizontal plate 103, located on one side of the slide groove 109.

[0036] The transverse bearing plate 116 has several pressure sensor mounting slots 117 arranged in a horizontal, straight line.

[0037] Pressure sensor mounting slot 117 is equipped with pressure sensors 118 with signal lines.

[0038] The end face of the pressure sensor mounting groove 117 is provided with a transition pressure bearing boss 119 for use with the pressure sensor 118 with signal line (one side of the transition pressure bearing boss 119 is fixedly attached to the surface of the pressure sensor 118 with signal line).

[0039] Among them, the power motor 105 (such as a 50W DC brushless motor with model number TC0BLD50) and the pressure sensor 118 with signal line (such as a spoke-type tension and compression force sensor with model number KWR75S) are respectively connected to the PLC controller 102 (such as a simple PLC Chinese all-in-one machine with model number OHR-PR10).

[0040] Example 2: Based on Example 1, the environmentally friendly, moisture-proof and fire-resistant corrugated cardboard compressive strength testing device also includes a vertical support seat 107 set on the other end face of the horizontal platform 103 and located on the other side of the slide groove 109.

[0041] One end of the lead screw 108 passes through the vertical support 107 and is connected to the coupling 106. The support 107 is used to support and protect the lead screw 108 for rotation control, prevent deformation and ensure rotational stability.

[0042] Example 3: Based on Example 1 or Example 2, the environmentally friendly, moisture-proof and fire-resistant corrugated cardboard compressive strength testing device further includes screw grooves 114 respectively disposed in one side of the transition plate 113;

[0043] The pressure-applying part 115 and the screw groove 114 are connected by an external thread structure, and the contact surface between the pressure-applying part 115 and the corrugated cardboard 120 is configured as a circular structure, an arc structure or a needle-like structure, which is used to simulate the compressive strength test of the packaging box under different usage environments.

[0044] Example 4: Based on Example 1, Example 2 or Example 3, the environmentally friendly, moisture-proof and fire-resistant corrugated cardboard compressive strength testing device further includes a horizontal L-shaped limiting plate 104 symmetrically arranged on the outer wall of the same side end face of the horizontal bearing plate 116.

[0045] The corrugated cardboard 120 is vertically inserted into the cavity formed by the horizontal bearing plate 116 and the horizontal L-shaped limiting plate 104 through the horizontal L-shaped limiting plate 104 to prevent the corrugated cardboard 120 from sliding and shifting horizontally during the test, which would affect the accuracy of the test data acquisition.

[0046] In addition, preferably, the slider 110 and the horizontal plate 112 form a T-shaped structure (lubricating oil is injected into the groove 109), so that it can be precisely matched with the power motor 105, coupling 106, slider threaded hole 111, and lead screw 108 to achieve a stable horizontal pushing and pressing action of the horizontal plate 112, transition plate 113, and pressure application part 115; the transition pressure bearing boss 119 is made of stainless steel, which is durable and does not deform during use, so as to achieve timely pressure transition transmission to the pressure sensor 118 with signal line.

[0047] The working principle or structural principle of this environmentally friendly, moisture-proof, and fire-resistant corrugated cardboard compressive strength testing device:

[0048] During testing, the corrugated cardboard 120 is first vertically inserted into the cavity formed by the horizontal pressure plate 116 and the horizontal L-shaped limiting plate 104 through the horizontal L-shaped limiting plate 104. Then, the power motor 105 is started by the PLC controller 102. At this time, the power motor 105 rotates the lead screw 108 through the coupling 106. The rotating lead screw 108 drives the slider 110 to slide horizontally towards the horizontal pressure plate 116 in the slide groove 109 through the slider thread hole 111. Finally, the horizontal plate 112 and the transition plate 113 on the slider 110 drive the pressure part 115 to contact the surface of the corrugated cardboard 120 and continuously apply pressure. At this time, the pressure is transmitted to the pressure sensor 118 with signal line through the transition pressure bearing boss 119 on the other side of the corrugated cardboard 120. The PLC controller 102 receives the pressure information of the pressure sensor 118 with signal line in real time and displays it.

[0049] During testing, the applied pressure (pressure information) is preset in the PLC controller 102. When the pressure information received by the pressure sensor 118 with signal line received by the PLC controller 102 is the same as the preset value of the PLC controller 102, the PLC controller 102 controls the power motor 105 to stop and reverse through the coupling 106, lead screw 108, slider threaded hole 111, and slider 110 to slide horizontally back to its original position in the slide groove 109 (the horizontal plate 112 and transition plate 113 drive the pressure part 115 to also reset). At this time, the corrugated cardboard 120 is lifted vertically and the pressure-bearing surface of the corrugated cardboard 120 can be observed and tested.

[0050] As mentioned above, the pressure (pressure information) preset in the PLC controller 102 can be input differently according to different test needs to complete different compressive strength tests.

[0051] The skid-mounted platform 100, motor mounting platform 101, PLC controller 102, and pressure sensor 118 with signal line in this environmentally friendly, moisture-proof, and fire-resistant corrugated cardboard compressive strength testing device are all conventional components or equipment. These will not be elaborated upon in this application.

[0052] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
