Description

Technical Field

[0001] The utility model relates to the field of carton compression test, in particular to a packaging carton compression test tool. Background Art

[0002] Cartons are the most widely used packaging products. They are divided into various specifications and models according to different materials. Cartons need to undergo compression tests after batch production. Pressure is applied to the cartons to test their compression resistance, thereby avoiding damage or deformation during the packaging process. Generally, special gauges are used to perform compression tests on cartons. These gauges are mostly driven by a driving mechanism to push down a pressure plate equipped with a high-precision force sensor.

[0003] The traditional carton compression tester still has certain shortcomings during use: First, when using the traditional compression tester, it is necessary to quickly adjust the height of the upper pressure plate according to the height of the carton of that specification until the upper pressure plate is very close to the top of the carton. This is because the upper pressure plate will descend at a very slow speed when it is officially performing pressure testing. In many cases, the descent speed of the upper pressure plate is measured in millimeters per minute, but because the upper pressure plate is large and the carton is on its inside, the staff has to pause and bend down to check the height every time they adjust it, which is very troublesome to operate. Secondly, when replacing a new force sensor or dismantling the structure, the four corners of the upper pressure plate need to be leveled. The current leveling work requires a tape measure to measure slowly, and the process is cumbersome.

[0004] Therefore, it is necessary to provide a new packaging carton compression test tool to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a packaging carton compression test tool which can conveniently level the four corners of an upper pressing plate and conveniently control the upper pressing plate to move to a suitable position on the upper side of the carton.

[0006] In order to solve the above technical problems, the utility model provides a packaging carton compression test tool, which includes: a support, a leveling auxiliary component and a height control component, wherein the leveling auxiliary component includes a central screw and a movable part, the bottom of the central screw is rotatably connected to the surface of the support, the movable part is threadedly connected to the central screw, the front and rear surfaces of the movable part are both symmetrically provided with connecting plates, the ends of the connecting plates are installed with pressure sensors and display screens, and the pressure sensor is electrically connected to the display screen on the adjacent side;

[0007] The height control assembly includes a first limit frame and a second limit frame, one side surface of the first limit frame and the second limit frame are both threadedly connected with a second bolt, the surface of the first limit frame is fixedly connected with a fixing piece, a scale is vertically installed on the surface of the fixing piece, a track is provided on the surface of the fixing piece located on one side of the scale, a sliding piece is slidably connected to the surface of the track, an extension plate is vertically provided on the front wall of the sliding piece, a buzzer and a touch switch are respectively installed on the extension plate, the touch switch is electrically connected to the buzzer, a touch block is fixedly connected to the surface of one side wall of the second limit frame, the touch block is located on the upper side of the touch switch, the top of the sliding piece is threadedly connected with the first bolt, and the end of the first bolt abuts against the track surface.

[0008] As a further solution of the utility model, vertical screws are threadedly connected on both sides of the support member, a frame body is provided on the outside of the two vertical screws, the vertical screws are rotatably connected to the inner wall of the frame and a belt is connected between the two vertical screws, and a driving motor is installed on the top of the vertical screw on one side.

[0009] Through the above technical solution, the driving motor drives the two vertical screws to rotate, and then the movable part drives the upper pressure plate to move downward to perform a pressure resistance test on the cartons on the bottom plate.

[0010] As a further solution of the utility model, mounting parts are fixedly connected to the bottom surfaces of the left and right sides of the support member, an upper pressure plate is provided on the lower side of the mounting member, the upper pressure plate is located inside the frame body, fixing rods are provided at the four corners of the surface of the upper pressure plate, the fixing rods penetrate the surface of the mounting member on one side and are threadedly connected with a nut, a spring member is provided between the nut and the mounting member, and the top of the spring member is rotatably connected to the nut.

[0011] Through the above technical solution, after disassembling and repairing components or replacing the force sensor, the four corners of the upper pressure plate are prone to uneven bottom surfaces due to different nut positions, which will affect the data accuracy of the compression test. At this time, the user can rotate the center screw to drive the movable part downward until the bottom of the pressure sensor abuts against the top surface of the upper pressure plate. At this time, each display screen will transmit the pressure value at the corner, and then the nut at this location will be rotated to keep the pressure sensor values ​​at the four corners uniform, so that the bottom surface of the upper pressure plate is parallel to the top surface of the base plate. This design can detect the status of the upper pressure plate in real time and assist the staff in leveling the four corners. The structural design provides great help to the workers' work.

[0012] As a further solution of the utility model, a bottom plate is arranged at the lower side of the upper pressing plate, the size of the bottom plate matches the size of the upper pressing plate, and the bottom plate is installed on the inner side of the frame.

[0013] With the above technical solution, the carton to be tested needs to be placed at the center position of the upper side of the bottom plate during operation, and then the driving mechanism is used to drive the upper pressure plate downward to complete the compressive strength test of the carton.

[0015] Through the above technical solution, when using the traditional compression test fixture, it is necessary to quickly adjust the height of the upper pressure plate according to the height of the carton of that specification until the upper pressure plate is very close to the top of the carton. This is because the upper pressure plate will descend at a very slow speed when officially performing pressure testing. In many cases, the descending speed of the upper pressure plate is measured in millimeters per minute, but because the upper pressure plate is large and the carton is on its inside, the staff has to pause and bend down to check the height every time they adjust it, which is very troublesome to operate. In this design, the position of the sliding part can be adjusted according to the height of the carton, and then the user can quickly lower the height of the upper pressure plate through the control module on one side. During the process, the touch block installed on the upper pressure plate will touch the surface of the touch switch, so that the alarm function of the buzzer is turned on and the upper pressure plate stops working. The structural design can provide greater convenience for the staff.

[0016] As a further solution of the utility model, a communicating vessel is provided at the edge of the surface of the bottom plate, a plurality of blowing heads are installed on the surface of the communicating vessel, and the communicating vessel is connected to an air pump through a pipeline.

[0017] Through the above technical solution, after the structure completes the compression test of the carton, more impurities and dust are likely to accumulate on the surface of the bottom plate. At this time, the user can turn on the air pump to supply air to several blowers to remove the impurities on the bottom plate.

[0018] As a further solution of the utility model, a force sensor is installed between the upper pressure plate and the support member, and the surfaces of the support member located on both sides of the central screw are fixedly connected to limit rods, and the movable member is slidably connected to the limit rods.

[0019] Through the above technical solution, when the upper pressure plate squeezes the carton, the force sensor will detect the corresponding force data, and the limit rod is designed to enable the movable parts to achieve stable height lifting.

[0020] Compared with the related art, the packaging carton compression test tool provided by the utility model has the following beneficial effects:

In the utility model, when the traditional compression tester is used, it is necessary to quickly adjust the height of the upper pressure plate according to the height of the carton of the specification, until the upper pressure plate is very close to the top of the carton, which is because the upper pressure plate will descend at a very slow speed when it is officially performing pressure detection. In many cases, the descending speed of the upper pressure plate is measured in millimeters per minute, but because the upper pressure plate is large and the carton is inside it, the staff has to pause and bend down to check the height every time they adjust it, which is very troublesome to operate. In this design, the position of the sliding part can be adjusted according to the height of the carton, and then the user can quickly lower the height of the upper pressure plate through the control module on one side. During the process, the touch block installed on the upper pressure plate will touch the surface of the touch switch, so that the alarm function of the buzzer is turned on and the upper pressure plate stops working.

[0022] 2.

[0033] like Figure 1-4 As shown, vertical screws 4 are threadedly connected on both sides of the support 10, a frame body 1 is arranged on the outside of the two vertical screws 4, the vertical screws 4 are rotatably connected to the inner wall of the frame body 1, and a belt 3 is connected between the two vertical screws 4, and a driving motor is installed on the top of the vertical screw 4 on one side.

[0034] The two vertical screws 4 are driven by a driving motor to rotate, and then the movable member 20 drives the upper pressure plate 6 to move downward, so as to perform a pressure resistance test on the cartons on the bottom plate 7.

[0035] like Figure 1-4 As shown, mounting members 15 are fixedly connected to the bottom surfaces of the left and right sides of the support member 10, an upper pressure plate 6 is arranged on the lower side of the mounting member 15, the upper pressure plate 6 is located on the inner side of the frame body 1, and fixing rods 16 are arranged at the four corners of the surface of the upper pressure plate 6, the fixing rod 16 passes through the surface of the mounting member 15 on one side and is threadedly connected with a nut 21, a spring member is arranged between the nut 21 and the mounting member 15, and the top of the spring member is rotatably connected to the nut 21.

[0036] After disassembling and repairing components or replacing the force sensor 19, the four corners of the upper pressure plate 6 are prone to uneven bottom surfaces due to the different positions of the nuts 21, which will affect the data accuracy of the compression test. At this time, the user can rotate the center screw 14 to drive the movable part 20 to move downward until the bottom of the pressure sensor 17 abuts against the top surface of the upper pressure plate 6. At this time, each display screen 18 will transmit the pressure value at the corner, and then rotate the nut 21 there to keep the values ​​of the pressure sensors 17 at the four corners uniform, so that the bottom surface of the upper pressure plate 6 is parallel to the top surface of the base plate 7. This design can detect the status of the upper pressure plate 6 in real time and assist the staff in leveling the four corners. The structural design provides great help to the workers' work.

[0037] like Figure 1-4 As shown, a bottom plate 7 is disposed at the lower side of the upper pressing plate 6 , the size of the bottom plate 7 matches the size of the upper pressing plate 6 , and the bottom plate 7 is installed on the inner side of the frame 1 .

[0038] During operation, the carton to be tested needs to be placed at the center position on the upper side of the bottom plate 7, and then the upper pressing plate 6 is driven downward by the driving mechanism to complete the compressive strength test of the carton.

[0039] like Figure 1-4 As shown, a control module 5 is disposed on one side of the frame 1 , the drive motor is electrically connected to the control module 5 , and an indicator needle is fixedly connected to one side surface of the sliding member 28 , and the indicator needle is located on one side of the scale 27 .

[0040] When using a traditional compression tester, it is necessary to first quickly adjust the height of the upper pressure plate 6 according to the height of the carton of that specification, until the upper pressure plate 6 is very close to the top of the carton and then stops. This is because the upper pressure plate 6 will descend at a very slow speed when officially performing pressure testing. In many cases, the descending speed of the upper pressure plate 6 is measured in millimeters per minute, but because the upper pressure plate 6 is large and the carton is inside it, the staff has to pause and bend down to check the height every time they adjust it, which is very troublesome to operate. In this design, the position of the sliding member 28 can be adjusted according to the height of the carton, and then the user can quickly lower the height of the upper pressure plate 6 through the control module 5 on one side. During the process, the touch block 29 installed on the upper pressure plate 6 will touch the surface of the touch switch 2, so that the alarm function of the buzzer 22 is turned on and the operation of the upper pressure plate 6 is stopped. The structural design can provide greater convenience for the staff.

[0041] like Figure 1-4 As shown, a communicating vessel 11 is provided at the edge of the surface of the bottom plate 7, a plurality of blowing heads are installed on the surface of the communicating vessel 11, and the communicating vessel 11 is connected to an air pump 12 through a pipeline.

[0042] After the compression test of the carton is completed, more impurities and dust are likely to accumulate on the surface of the bottom plate 7. At this time, the user can turn on the air pump 12 to supply air to several blowers to remove the impurities on the bottom plate 7.

[0043] like Figure 1-4 As shown, a force sensor 19 is installed between the upper pressure plate 6 and the support member 10, and the surfaces of the support member 10 located on both sides of the central screw 14 are fixedly connected to limit rods, and the movable member 20 is slidably connected to the limit rods.

[0044] When the upper pressing plate 6 squeezes the carton, the force sensor 19 will detect the corresponding force data, and the design of the limit rod is to enable the movable part 20 to achieve stable height lifting.

[0045] The working principle of a packaging carton compression test tool provided by the utility model is as follows:

[0046] The first step: When using the traditional compression tester, it is necessary to quickly adjust the height of the upper pressing plate 6 according to the height of the carton of the specification, until the upper pressing plate 6 is very close to the top of the carton and then stops. This is because the upper pressing plate 6 will descend at a very slow speed when it is officially performing the pressure detection work. In many cases, the descending speed of the upper pressing plate 6 is measured in millimeters per minute, but because the upper pressing plate 6 is large and the carton is inside it, the staff has to pause and bend down to check the height every time they adjust it, which is very troublesome to operate. In this design, the position of the sliding member 28 can be adjusted according to the height of the carton, and then the user can quickly lower the height of the upper pressing plate 6 through the control module 5 on one side. During the process, the touch block 29 installed on the upper pressing plate 6 will touch the surface of the touch switch 2, so that the alarm function of the buzzer 22 is turned on and the upper pressing plate 6 stops working. The structural design can provide greater convenience for the staff;

[0047] The second step: After disassembling and repairing components or replacing the force sensor 19, the four corners of the upper pressure plate 6 are prone to uneven bottom surfaces due to the different positions of the nuts 21, which will affect the data accuracy of the compression test. At this time, the user can rotate the center screw 14 to drive the movable part 20 to move downward until the bottom of the pressure sensor 17 abuts against the top surface of the upper pressure plate 6. At this time, each display screen 18 will transmit the pressure value at the corner, and then rotate the nut 21 there to keep the values ​​of the pressure sensors 17 at the four corners uniform, so that the bottom surface of the upper pressure plate 6 is parallel to the top surface of the bottom plate 7. This design can detect the status of the upper pressure plate 6 in real time and assist the staff in leveling the four corners. The structural design provides great help to the workers' work.
