Description

Technical Field

[0001] The present invention relates to the technical field of carton testing, and particularly to a device for detecting the compressive performance of paper products. Background Art

[0002] After the production of packaging cartons, it is necessary to conduct sampling inspections on the packaging cartons and carry out multiple quality tests on them to achieve a comprehensive evaluation of the carton performance.

[0003] Chinese Patent CN216695813U discloses a device for testing the hardness of paper boxes, including a device main body. The device main body includes a base, support feet, a crossbar frame, a vertical bar frame, and a control box. The inside of the first compression plate includes a guide seat, a spring, a connecting seat, and a piercing rod, which are divided into three or more. First, through the start control button in the control box, and then through the button in the start control button, the piercing rod is opened. The paper box is placed through the second compression plate. The start control button controls the hardness testing mechanism. The nut seat slides down in the slider. The start control button controls the pushing force of the piercing rod to test the paper box. The pressure sensor senses the pressure signal and feeds back the data information of the compressive hardness of the tested paper box to the display screen in the control box for display. Through such a setting, the compressive ability of the paper box hardness can be reflected, that is, the puncture resistance strength of the carton. However, the carton may be subjected to various types of impacts and pressures during transportation, and it is difficult for this testing device to simulate the comprehensive performance of the carton in the real transportation state.

[0004] Based on this, the present invention designs a device for detecting the compressive performance of paper products to solve the above problems. Summary of the Invention

[0013] Furthermore, the split-type static pressure testing mechanism includes a lifting beam, a connecting beam, a pressing plate and a pressure sensor. A lifting device is arranged inside the column, and the mobile end of the lifting device is fixedly connected to the lifting beam; a plurality of connecting beams are fixedly installed on the lifting beam; two pressing plates are arranged and distributed on the front and rear sides of the lifting beam. A pressure sensor is fixedly installed at the upper end of the pressing plate, and the connecting beam is connected to the pressure sensor through a fastener.

[0014] Furthermore, the dynamic pressure testing mechanism includes a rotary impact component and an energy storage component. A support platform is fixedly installed on the base platform, and the rotary impact component and the energy storage component are installed on the support platform. The rotary impact component is used to apply an impact force to the top of the carton, and the energy storage component is used to store energy for the rotary impact component to increase the impact force of the rotary impact component.

[0015] Furthermore, the rotary impact component includes a bracket, a rotating shaft, an encoder, a pneumatic clutch, a reduction motor, an impact rod and an impact plate. The bracket is fixedly connected to the support platform, the rotating shaft is rotatably connected to the bracket through a bearing, and an encoder connected to the rotating shaft is arranged on the bracket. The encoder is used to read rotation parameters such as the angular displacement and angular velocity of the rotating shaft; the reduction motor is fixedly connected to the support platform, and the output end of the reduction motor is connected to the rotating shaft through a pneumatic clutch; one end of the impact rod is fixedly connected to the rotating shaft, and the other end of the impact rod is fixedly connected to the impact plate through a fastener.

[0016] Furthermore, the energy storage component includes a vertical plate, a sliding rod, a fixed block, a movable block and a spring.

The control pin is fixedly connected to the side wall of the column, and a control groove for the control pin to slide in a limited manner is formed on the connecting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The cardboard box is placed on the moving end of the linear slide table. The block-type static pressure testing mechanism can apply a downward pressure to the cardboard box from the top of the cardboard box to test the overall static compressive performance of the cardboard box. Through the adjustable single-corner positioning component, a part of the cardboard box is exposed outside the moving end of the linear slide table and cooperates with the block-type static pressure testing mechanism to apply pressure to the exposed part of the cardboard box to test the local static compressive performance of the cardboard box.

[0020] 2. In the present invention, the reduction motor and the pneumatic clutch cooperate to drive the rotating shaft to rotate, so that the impact plate hits the top of the cardboard box to test the impact resistance of the cardboard box. When the impact rod is lifted, the spring will achieve a energy storage effect, effectively increasing the initial velocity of the impact plate and the impact ability of the impact plate when the rotation angle of the rotating shaft remains unchanged. Different impact effects can be achieved by replacing impact plates with different materials and shapes, and the position of the fixed block on the sliding rod can also be changed to increase the energy storage effect.

[0021] 3. In the present invention, the baffle has two states: contraction and expansion. In the expanded state, the two baffles abut against each other to form an occlusion box, such that the baffle is in the expanded state. At this time, water droplets are sprayed onto the surface of the cardboard box through a nebulizing nozzle to simulate the humidity environment during transportation of the cardboard box, and the humidity around the cardboard box is monitored through a humidity sensor. In the contracted state, the top of the baffle is lower than the top of the cardboard box, so as to avoid interfering with the static compressive strength test of the cardboard box, and the water droplets and water mist inside the cover can quickly disperse, without affecting subsequent humidity simulation operations.

[0037] A dynamic pressure testing mechanism 6 is also arranged on the base 1 for testing the impact resistance of the carton 8;

[0038] Two split humidity control components 7 are symmetrically arranged on the columns 2 on both sides for simulating the compressive performance of the carton 8 in different humidity environments.

[0039] In the invention, the carton 8 is placed on the mobile end of the linear slide. The carton 8 is placed on the mobile end of the linear slide. The block-type static pressure testing mechanism 4 can apply downward pressure to the carton 8 from the top of the carton 8 to test the overall static compressive performance of the carton 8. The adjustable single-angle positioning component enables a part of the carton 8 to be exposed outside the mobile end of the linear slide and cooperate with the block-type static pressure testing mechanism 4 to apply pressure to the exposed part of the carton 8 to test the local static compressive performance of the carton 8.

[0040] Please refer to Figure 2 、 Figure 6 and Figure 7 The linear slide includes a linear guide rail 51 and a support plate 52. The linear guide rail 51 is fixedly installed at the upper end of the base 1. The support plate 52 is limited and slidably connected to the linear guide rail 51 through a slider. The slider between the linear guide rail 51 and the support plate 52 is a lockable slider, so that the support plate 52 can be locked and fixed at any position on the linear guide rail 51;

[0041] The adjustable single-angle positioning component includes a positioning angle iron 53 and a slider 54.

[0042] The block-type static pressure testing mechanism 4 includes a lifting beam 41, a connecting beam 42, a pressing plate 43, a first screw 44, a first locking nut 45, and a pressure sensor 46. A lifting device is arranged inside the column 2. The lifting device adopts a mature technology in the field, such as a lead screw linear module lifting structure, which will not be elaborated too much in this article. The moving end of the lifting device is fixedly connected to the lifting beam 41. A plurality of connecting beams 42 are fixedly installed on the lifting beam 41. Two pressing plates 43 are arranged and distributed on the front and rear sides of the lifting beam 41.

By adjusting the height of the front pressing plate 43 in cooperation with the first screw 44 and the first locking nut 45, the height of the front pressing plate 43 is made lower than that of the rear pressing plate 43. The support plate 52 is moved so that the front edge of the support plate 52 and the joint of the two pressing plates 43 are in the same vertical plane. Subsequently, the slider 54 is slid to adjust the position of the positioning angle iron 53 to control the size of the part of the carton 8 exposed from the support plate 52. The two pressing plates 43 move vertically downward. The front pressing plate 43 is used to press down the exposed part of the carton 8, and the rear pressing plate 43 is used to fix the unexposed part of the carton 8 on the support plate 52, thereby realizing the local compressive performance test of the carton 8.

[0044] Please refer to Figure 2 and Figure 5 , the dynamic pressure testing mechanism 6 includes a rotary impact assembly 61 and an energy storage assembly 62. A support table is fixedly installed on the base 1. The rotary impact assembly 61 and the energy storage assembly 62 are installed on the support table. The rotary impact assembly 61 is used to provide an impact force to the top of the carton 8, and the energy storage assembly 62 is used to store energy for the rotary impact assembly 61 to increase the impact force of the rotary impact assembly 61.

[0045] The rotary impact assembly 61 includes a bracket 611, a rotating shaft 612, an encoder 613, a pneumatic clutch 614, a reduction motor 615, an impact rod 616, an impact plate 617, a second screw 618, and a second locking nut 619. The bracket 611 is fixedly connected to the support table. The rotating shaft 612 is rotatably connected to the bracket 611 through a bearing. An encoder 613 connected to the rotating shaft 612 is provided on the bracket 611.

[0047] The energy storage assembly 62 includes a vertical plate 621, a sliding rod 622, a fixed block 623, a movable block 624, and a spring 625. The vertical plate 621 is fixedly installed on the support table. A sliding rod 622 is fixedly installed at the top of the vertical plate 621, and the end of the sliding rod 622 away from the vertical plate 621 is inclined downward. The fixed block 623 is fixedly connected to the sliding rod 622, the movable block 624 is slidably connected to the sliding rod 622 with a limit, and the spring 625 is sleeved outside the sliding rod 622. The two ends of the spring 625 are respectively fixedly connected to the fixed block 623 and the movable block 624.

[0048] In the present invention, when the pneumatic clutch 614 is in the closed state, the rotating shaft 612 and the output end of the reduction motor 615 rotate synchronously. The reduction motor 615 can drive the rotation of the rotating shaft 612, and with the cooperation of the encoder 613, the rotating shaft 612 can be rotated to a set height. When the pneumatic clutch 614 is in the released state, the rotating shaft 612 can rotate freely, so that the impact plate 617 hits the top of the cardboard box 8 to test the impact resistance of the cardboard box 8. When the rotating shaft 612 drives the impact rod 616 to lift, the movable block 624 will be pushed towards the fixed block 623, and the energy storage effect is achieved through the spring 625. Without changing the rotation angle of the rotating shaft 612, the initial velocity of the impact plate 617 can be effectively increased, the impact ability of the impact plate 617 can be increased, and different impact effects can be achieved by replacing the impact plates 617 with different materials and shapes. The position of the fixed block 623 on the sliding rod 622 can also be changed to increase the energy storage effect.

[0049] Please refer to Figure 4, the split-type humidity control component 7 includes a baffle 71, an atomizing nozzle 72, a cylinder 73, a connecting plate 74, a control groove 75 and a control pin 76. The cylinder 73 is fixedly connected to the column 2. The baffle 71 is slidably installed at the output end of the cylinder 73. When the baffles 71 of the two split-type humidity control components 7 are closed, they form a shielding box with an open bottom side; the connecting plate 74 is fixedly connected to the baffle 71 and is in sliding fit with the side wall of the column 2. The control pin 76 is fixedly connected to the side wall of the column 2. A control groove 75 for limiting sliding connection with the control pin 76 is formed on the connecting plate 74. The control groove 75 is composed of an inclined groove and a horizontal groove. When the control pin 76 slides in the inclined groove, it will drive the baffle 71 to move upward to completely shield the carton 8; a plurality of atomizing nozzles 72 are fixedly installed on the inner wall of the baffle 71. The atomizing nozzles 72 are connected to an external water supply structure through a hose, such as a water storage tank equipped with a water pump; a humidity sensor is arranged inside the baffle 71;

[0050] In the present invention, the baffle 71 has two states: contraction and expansion. In the contraction state, the top of the baffle 71 is lower than the top of the carton 8 to avoid interfering with the static compression test of the carton 8. The cylinder 73 is used to control the baffle 71 to approach the carton 8. Under the cooperation of the control groove 75 on the connecting plate 74 and the control pin 76, the baffle 71 first moves obliquely upward and then horizontally until the two baffles 71 abut against each other to form a shielding box, so that the baffle 71 is in the expanded state. At this time, water droplets are sprayed onto the surface of the carton 8 through the atomizing nozzles 72 to simulate the humidity environment of the carton 8 during transportation, and the humidity sensor is used to monitor the humidity around the carton 8. After a certain period of time, the baffle 71 resets, so that the baffle 71 returns to the contraction state again, and the water droplets and water mist in the baffle 71 can quickly dissipate without affecting the subsequent humidity simulation operation.
