[0001] This utility model relates to the field of cardboard box compression testing technology, specifically a cardboard box compression testing instrument with rapid loading and unloading capabilities. Background Technology

[0002] The carton compression test is used to evaluate the carton's resistance to compression during transportation and storage to ensure that the product can withstand various pressure conditions without damage. This test is usually conducted using a carton compression tester, which simulates the pressure conditions during actual transportation and stacking by applying gradually increasing pressure, and records the maximum pressure and deformation of the carton to evaluate its compression resistance.

[0003] The existing carton compression tester consists of an outer shell, a support platform, a hydraulic cylinder, and a pressure plate. In use, the carton is placed on the support platform connected to the outer shell, and the hydraulic cylinder is activated to push the pressure plate at the bottom to apply pressure to the carton. The pressure value is recorded during the pressure application process. However, after the carton compression tester completes the test, the operator needs to manually clean the carton and debris on the support platform, which takes more time and effort and reduces the efficiency of the carton compression tester. Utility Model Content

[0004] The purpose of this invention is to provide a carton compression tester that can quickly load and unload materials, in order to solve the problem mentioned in the background art that after the carton compression tester completes the pressure test, the operator needs to manually clean the carton and debris on the upper side of the support platform, which reduces the working efficiency of the carton compression tester.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carton compression tester with rapid loading and unloading capabilities, comprising a pressure testing chamber, a hydraulic push rod, and a pressure testing plate. The hydraulic push rod is provided through the top of the pressure testing chamber, and an mounting plate is provided at the bottom of the hydraulic push rod. The pressure testing plate is mounted at the bottom of the mounting plate.

[0006] The pressure testing box has an inlet and a outlet on both sides. A support frame is welded to the side of the pressure testing box near the inlet. A feeding push plate is inserted into the support frame. An unloading push plate is provided at the bottom of the pressure testing box. A first connecting rod and a second connecting rod are welded to one side of the feeding push plate and the unloading push plate, respectively. The adjacent sides of the first connecting rod and the second connecting rod are connected to one end of the electric telescopic rod. The other end of the electric telescopic rod is connected to the pressure testing box.

[0007] Preferably, the feed inlet is located above the discharge outlet, and the first connecting rod, the second connecting rod, and the electric telescopic rod are all symmetrically arranged about one side of the pressure testing box.

[0008] Preferably, the pressure testing box has a reserved slot inside, which is located below the feed inlet.

[0009] Preferably, a discharge pusher plate is inserted into the reserved slot, and the bottom of the discharge pusher plate is in contact with the inner wall of the pressure testing box.

[0010] Preferably, the support frame has symmetrically provided temporary storage slots inside, and the insertion dimensions of the temporary storage slots match those of the first connecting rod.

[0011] Preferably, a control box is installed on the top of the pressure testing box, a control panel is installed on one side of the control box, and heat dissipation holes are equidistantly opened on the other side of the control box.

[0012] Preferably, the hydraulic push rod is connected to a mounting base on its outer side, and the mounting base is connected to the pressure measuring box by a locking bolt.

[0013] Preferably, multiple pressure equalizing rods are welded to the bottom of the hydraulic push rod, and the side of the multiple pressure equalizing rods away from the hydraulic push rod is welded to the mounting plate, and the pressure equalizing rods are arranged at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This carton compression tester with rapid loading and unloading can quickly load and unload cartons by extending and retracting the electric telescopic rod, which is convenient and time-saving, and can effectively improve the working efficiency of the carton compression tester. The bottom of the hydraulic push rod is connected to the mounting plate through the pressure equalizing rod, which can evenly compress the carton, better monitor the force on various parts of the carton, and have a better compression simulation effect. It solves the problem that after the carton compression tester completes the pressure test, the operator needs to manually clean the carton and debris on the upper side of the support platform, which reduces the working efficiency of the carton compression tester.

[0015] 1. This rapid loading and unloading carton compression tester facilitates quick loading and unloading of cartons. After the hydraulic push rod pushes the mounting plate and pressure plate to complete the compression test and fully resets, the electric telescopic rod on one side of the pressure test chamber is activated. Through the first connecting rod and the loading push plate, the carton is pushed into the inlet. The second connecting rod drives the unloading push plate to push out the carton and its residue that have completed the test inside the pressure test chamber and resets it. At this time, the carton on the upper side of the unloading push plate will automatically fall into the pressure test chamber to wait for the next test. This rapid loading and unloading carton compression tester can achieve rapid loading and unloading of cartons by extending and retracting the electric telescopic rod, which is convenient and time-saving, and can effectively improve the working efficiency of the carton compression tester.

[0016] 2. This rapid loading and unloading carton compression tester, to facilitate equal pressure on the corners of the carton by the mounting plate and pressure measuring plate, and to avoid the installation plate and pressure measuring plate tilting and affecting the subsequent test results, uses three equal-pressure rods at the bottom of the hydraulic push rod, which are then welded to the top of the mounting plate. When the hydraulic push rod drives the mounting plate and pressure measuring plate to abut against the upper side of the carton and gradually compress it through the equal-pressure rods, the thrust of the hydraulic push rod will be evenly distributed along the three identical equal-pressure rods. This rapid loading and unloading carton compression tester, with the bottom of the hydraulic push rod connected to the mounting plate through the equal-pressure rods, can evenly compress the carton, better monitor the force on various parts of the carton, and achieve better compression simulation effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a carton compression tester that can quickly load and unload materials, including a pressure test box 1, a hydraulic push rod 2 and a pressure test plate 202. The top of the pressure test box 1 is provided with a hydraulic push rod 2, the bottom of the hydraulic push rod 2 is provided with an mounting plate 201, and the bottom of the mounting plate 201 is installed with the pressure test plate 202.

[0024] The pressure testing box 1 has a feed inlet 3 and a discharge outlet 301 on both sides. A support frame 4 is welded to the side of the pressure testing box 1 near the feed inlet 3. A feeding push plate 401 is inserted into the support frame 4. A discharge push plate 402 is provided at the bottom of the pressure testing box 1. A first connecting rod 403 and a second connecting rod 404 are welded to one side of the feeding push plate 401 and the discharge push plate 402, respectively. The adjacent sides of the first connecting rod 403 and the second connecting rod 404 are connected to one end of the electric telescopic rod 405. The other end of the electric telescopic rod 405 is connected to the pressure testing box 1.

[0025] The feed inlet 3 is located above the discharge outlet 301. The first connecting rod 403, the second connecting rod 404 and the electric telescopic rod 405 are symmetrically arranged about one side of the pressure testing box 1. The pressure testing box 1 has a reserved slot 5 inside, which is located below the feed inlet 3. A discharge push plate 402 is inserted into the reserved slot 5, and the bottom of the discharge push plate 402 is in contact with the inner wall of the pressure testing box 1. The support frame 4 has symmetrically arranged temporary storage slots 501 inside, and the insertion size of the temporary storage slots 501 matches the first connecting rod 403.

[0026] In specific implementation, to facilitate the rapid loading and unloading of the carton compression tester, after the hydraulic push rod 2 pushes the mounting plate 201 and the pressure plate 202 to complete the compression test and fully reset, the electric telescopic rod 405 on one side of the pressure test chamber 1 is activated. At this time, the electric telescopic rod 405 retracts and pushes the carton inside the support frame 4 towards the side where the feed port 3 is located through the first connecting rod 403 and the feeding push plate 401 until the carton is completely pushed into the feed port 3. At this time, the second connecting rod 404 will drive the unloading push plate 402 to push out the carton and its residue that have completed the test inside the pressure test chamber 1. After the residue is pushed out, the electric telescopic rod 405 will drive the feeding push plate 401 and the unloading push plate 402 to reset through the first connecting rod 403 and the second connecting rod 404. At this time, the carton on the upper side of the unloading push plate 402 will automatically fall into the pressure test chamber 1 to wait for the test to continue.

[0027] The bottom of the unloading push plate 402 inside the reserved slot 5 is in contact with the inner wall of the pressure test chamber 1, which facilitates the better ejection of the residue inside the pressure test chamber 1. The temporary storage slot 501 facilitates the movement of the first connecting rod 403. This carton compression tester, which can quickly load and unload cartons, can realize the rapid loading and unloading of cartons by extending and retracting the electric telescopic rod 405, which is convenient and time-saving and can effectively improve the working efficiency of the carton compression tester.

[0028] See Figure 1 and Figure 4 It can be seen that a control box 6 is installed on the top of the pressure measuring box 1, a control panel 601 is installed on one side of the control box 6, and heat dissipation holes 602 are equidistantly opened on the other side of the control box 6. A mounting base 7 is connected to the outside of the hydraulic push rod 2, and the mounting base 7 is connected to the pressure measuring box 1 by locking bolts. Multiple pressure equalizing rods 701 are welded to the bottom of the hydraulic push rod 2. The side of the multiple pressure equalizing rods 701 away from the hydraulic push rod 2 is welded to the mounting plate 201, and the pressure equalizing rods 701 are equidistantly arranged.

[0029] In practical implementation, to facilitate equal pressure on the corners of the carton by the mounting plate 201 and the pressure measuring plate 202, and to avoid the installation plate 201 and the pressure measuring plate 202 tilting due to pressure, which would affect the subsequent test results, the bottom of the hydraulic push rod 2 is welded to the top of the mounting plate 201 by three equal-pressure rods 701 at equal intervals. When the hydraulic push rod 2 drives the mounting plate 201 and the pressure measuring plate 202 to abut against the upper side of the carton and gradually compress it through the equal-pressure rods 701, the thrust of the hydraulic push rod 2 will be evenly distributed along the three identical equal-pressure rods 701, thereby compressing the corners of the carton. This carton compression tester, which can quickly load and unload materials, has the bottom of the hydraulic push rod 2 connected to the mounting plate 201 through the equal-pressure rods 701, which can evenly compress the carton, better monitor the force on various parts of the carton, and achieve better compression simulation effect.

[0030] In summary, when using this carton compression tester with rapid loading and unloading, the control panel 601 sends a command to the control box 6 to control the electric telescopic rod 405 to push the carton into the feed inlet 3. This, in turn, drives the unloading push plate 402 to push out the tested carton and its residue from the pressure testing chamber 1. After resetting, the carton on the upper side of the unloading push plate 402 automatically falls into the pressure testing chamber 1. The hydraulic push rod 2 is then activated to push the mounting plate 201 and the pressure testing plate 202 downwards to compress the carton. The pressure testing plate 202 transmits the pressure data to the control box 6, which is then displayed on the control panel 601. The heat dissipation hole 602 is used for heat dissipation in the control box 6, and the mounting base 7 is used for mounting the carton. Content not described in detail in this specification is prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
