Description

Technical Field

[0001] This invention relates to the field of pressure resistance testing technology, and more specifically, to a packaging pressure resistance testing device. Background Technology

[0002] In new materials-related services, packaging pressure resistance testing devices test packaging by applying stable pressure. Their core function is to test and evaluate the pressure resistance of packaging materials and prevent the risk of damage caused by external forces during distribution.

[0003] Among existing publicly available documents, Chinese Patent Publication No. CN207850829U discloses a high-efficiency automated packaging bag compression testing device for a mesh conveyor. This technology uses a drive motor to drive belt drive rollers, which in turn drives the belt to rotate. Simultaneously, belt guide plates are installed between the belt drive rollers, ensuring that the belt rotates synchronously with the mesh conveyor at all times, without interruption during compression testing, and capable of withstanding significant pressure, effectively improving the efficiency of pressure testing. However, this technology has the following drawbacks.

[0004] In the pressure resistance testing of new material packaging objects, the corner areas of the packaging are divided into top, middle and bottom, and each part needs to be subjected to stable pressure testing at different angles and directions. Each point needs to be adjusted in position and tilted at a specified angle, and the specific position for pressure resistance testing must be adjusted separately for each point. The amount of preparation work is huge. This complex operation makes it difficult to carry out simultaneous pressure resistance testing on different corner points and different angles of the packaging, and it is difficult to meet the testing needs of multiple parts and multiple angles at one time. As a result, the pressure resistance testing process is cumbersome when applying stable pressure, which greatly reduces the efficiency of pressure resistance testing. Summary of the Invention

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention utilizes a linkage pressure operation driven by a diagonal pressure bar. A single power component drives the diagonal pressure bar to move downward at a set angle, simultaneously causing the top pressure block, the middle pressure block, and the bottom pressure block to move vertically downward, horizontally upward, and vertically upward, respectively. This applies pressure to various points at the corner of the packaging, enabling simultaneous, multi-angle pressure resistance testing of the top, middle, and bottom of the same corner of the packaging. This completely changes the cumbersome traditional method where each point needs to be adjusted individually and sequentially. It can meet the testing needs of multiple parts and multiple angles at the corner of the packaging in one go, greatly improving the efficiency of pressure resistance testing and ensuring the consistency of the stress state and testing conditions at each point.

[0017] 2. This invention employs precise motion conversion of the inclined frame, linkage rope, inclined sleeve strip, frame strip, and inclined sleeve plate. It can accurately decompose and convert the single longitudinal downward tilting motion of the inclined pressure bar into the lateral tilting motion of the middle pressure block and the longitudinal upward tilting motion of the bottom pressure block. The motion trajectories and angles of the middle and bottom pressure blocks are preset and interconnected through the mechanical structure, ensuring that even under complex angle requirements, the three detection points of the top pressure block, middle pressure block, and bottom pressure block can simultaneously, accurately, and stably reach the predetermined position and apply pressure. This not only avoids errors caused by manual adjustment but also significantly improves the efficiency of corner pressure resistance testing of packaging materials. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 - Figure 9 The packaging pressure resistance testing device shown includes a positioning plate 1, with an inclined pressure bar 2 positioned above the positioning plate 1; a top pressure component installed at the bottom end of the inclined pressure bar 2, with a top pressure block 3 on the top pressure component; a middle pressure component located on one side of the outer wall of the inclined pressure bar 2, with a middle pressure block 4 installed on the middle pressure component; a bottom pressure component located on the other side of the outer wall of the inclined pressure bar 2, with a bottom pressure block 5 on the bottom pressure component; and a power component installed at the top end of the inclined pressure bar 2. The power component drives the inclined pressure bar 2 to move longitudinally downward at an inclined angle, during which the inclined pressure bar 2 drives the top pressure block 3 to move downward. The pressure component moves longitudinally downwards synchronously at an inclined angle. The top pressure component drives the top pressure block 3 to move longitudinally downwards at an inclined angle. The top pressure block 3 simultaneously performs longitudinal downward compression detection on the top corner of the package. At the same time, the inclined pressure rod 2 drives the middle pressure component, which drives the middle pressure block 4 to perform lateral compression detection on the middle corner of the package at an inclined angle. Simultaneously, the inclined pressure rod 2 also drives the bottom pressure component to move longitudinally upwards at an inclined angle. Then, the bottom pressure component drives the bottom pressure block 5 to perform longitudinal upward compression detection on the bottom corner of the package at an inclined angle.

[0030] In this embodiment, as Figure 2As shown, the top pressure application component includes: two positioning blocks 6, both fixed to the lower inclined surface of the top pressure block 3, with an included angle between the two positioning blocks 6; and a first pressure sensor 7, installed on the upper inclined surface of the top pressure block 3, with its sensing end fixedly connected to the bottom end of the inclined pressure rod 2, and used to sense the compressive force of the inclined pressure rod 2. The vertical cross-sectional shape of both positioning blocks 6 is triangular, and the bottom end of the inclined pressure rod 2 is parallel to the upper inclined surface of the top pressure block 3.

[0031] When this technology is in use, the inclined pressure rod 2 drives the first pressure sensor 7 to tilt downwards longitudinally, and the top pressure block 3 drives the two positioning blocks 6 to tilt downwards longitudinally. The top pressure block 3 and the two positioning blocks 6 simultaneously apply longitudinal downward pressure to the top of the corner of the package, and the inclined pressure rod 2 presses against the sensing end of the first pressure sensor 7. In this way, pressure detection is achieved at different points and angles of the corner of the package.

[0032] In this embodiment, as Figure 1 - Figure 5 As shown, the central pressure-applying component includes: an inclined frame 8, fixed to one side of the outer wall of the inclined pressure rod 2, with an inclined column 9 fixed to the inner wall of the inclined frame 8, and a sleeve block 10 slidably sleeved on the inclined column 9; the inclined frame 8 is used to guide the sleeve block 10 to slide; a linkage rope 11, fixed to the upper inclined surface of the sleeve block 10, with an arc-shaped block 12 slidably provided on the inner wall of the linkage rope 11, and a limit sleeve 13 fixed at both ends of the outer wall of the arc-shaped block 12; a support bar 14, fixed to one side of the limit sleeve 13, with a linkage block 15 fixed at the bottom end of the linkage rope 11, and a horizontal inclined rod 16 fixed to one side of the linkage block 15; a second pressure sensor 17 installed at one end of the horizontal inclined rod 16, and the horizontal inclined rod 16 is fixedly connected to the sensing end of the second pressure sensor 17; the second pressure sensor 17 is fixedly connected to the central pressure block 4; and an inclined sleeve strip 19, installed on the outer wall of the horizontal inclined rod 16, which is used to guide the horizontal inclined rod 16 to slide, and is fixedly connected to the positioning plate 1. The support bar 14 is fixedly connected to the inclined sleeve bar 19, and the linkage rope 11 is used to move along the inside of the inclined sleeve bar 19.

[0033] When this technology is in use, when the inclined pressure bar 2 tilts downward longitudinally, the inclined frame 8 drives the inclined column 9 to tilt downward longitudinally. The inclined column 9 causes the sleeve block 10 to tilt downward longitudinally. The sleeve block 10 slides along the inner wall of the inclined frame 8. The sleeve block 10 pulls the top of the linkage rope 11. The linkage rope 11 slides in the limiting gap between the two limiting sleeves 13. The linkage rope 11 slides along the inner wall of the inclined sleeve 19. The bottom end of the linkage rope 11 pulls the linkage block 15 to tilt upward laterally. The horizontal inclined bar 16 tilts upward laterally along the inner wall of the inclined sleeve 19. The second pressure sensor 17 drives the middle pressure block 4 to tilt upward laterally at the same tilt angle. The middle pressure block 4 conducts lateral compression detection on the middle of the corner of the package at the same tilt angle. In this way, different points and different angle positions of the corner of the package are simultaneously pressured and detected.

[0034] In this embodiment, as Figure 5 As shown, two positioning sleeves 21 are fixed on one side of the inclined sleeve 19. A positioning post 20 is fixed on the inner wall of the positioning sleeve 21. Both the positioning post 20 and the positioning sleeve 21 are slidably connected to the linkage rope 11. The linkage rope 11 slides on the outer wall of the positioning post 20, and at the same time slides between the two positioning sleeves 21, so as to realize the limiting and guiding operation of the linkage rope 11.

[0035] In this embodiment, as Figure 1 - Figure 7 As shown, the bottom pressure application component includes: a frame strip 22, fixed to the other side of the outer wall of the inclined pressure rod 2; a sliding rod 23 sliding on the inner wall of the frame strip 22; a guide rod 24 fixed to one end of the sliding rod 23; an inclined sleeve plate 25, installed on the outer wall of the guide rod 24; the inclined sleeve plate 25 is used to guide the movement of the guide rod 24; the inclined sleeve plate 25 is fixedly connected to the positioning plate 1; and a third pressure sensor 26, installed at the top of the guide rod 24; the third pressure sensor 26 is used to sense the compressive force of the guide rod 24; the sensing end of the third pressure sensor 26 is fixedly connected to the guide rod 24; and a longitudinal block 18 is fixed between the third pressure sensor 26 and the bottom pressure block 5. The frame strip 22 and the guide rod 24 are slidably connected, and the longitudinal block 18 is inclined.

[0036] In use, the inclined pressure rod 2 drives the frame strip 22 to move longitudinally downward at a specified tilt angle, while the sliding rod 23 slides along the inner wall of the frame strip 22. The guide pressure rod 24 moves longitudinally upward along the inner wall of the inclined sleeve plate 25 at a specified tilt angle. The guide pressure rod 24 drives the third pressure sensor 26 to move longitudinally upward at a specified tilt angle. The longitudinal block 18 drives the bottom pressure block 5 to move longitudinally upward at a specified tilt angle. The bottom pressure block 5 synchronously moves longitudinally upward at the bottom corner of the package to squeeze and detect, providing synchronous pressure detection at different corner points and angles.

[0037] In this embodiment, as Figure 1 - Figure 9 As shown, the power components include: a socket plate 27, fixed to the top of the inclined pressure rod 2; a guide frame 29 is installed on the outer wall of the socket plate 27 for guiding the movement of the socket plate 27; a geared motor 30 is installed at the top of the guide frame 29; a screw 28 is threadedly connected to the inner wall of the socket plate 27, and the geared motor 30 drives the screw 28 to rotate within the inner wall of the guide frame 29; a mounting frame 31 is installed on the lower inclined surface of the guide frame 29; both the guide frame 29 and the positioning plate 1 are fixedly connected to the mounting frame 31; a controller 32 is installed on one side of the mounting frame 31, and the controller 32 is electrically connected to the geared motor 30. An insert plate 33 is slidably connected to the inner wall of the positioning plate 1 for positioning the packaged goods.

[0038] When this technology is in use, the controller 32 starts the reduction motor 30, the reduction motor 30 drives the screw 28 to rotate, the screw 28 drives the sleeve plate 27 to move longitudinally downward under the action of the thread meshing force, the sleeve plate 27 drives the inclined pressure rod 2 to move longitudinally downward, providing the extrusion power.

[0039] The working principle of the packaging pressure resistance testing device of the present invention is as follows.

[0040] First, when positioning the object, the bolt is inserted into the hole on the positioning plate 1 to lock and fix the positioning plate 1. Then, the insert plate 33 is moved upward, separating the insert plate 33 from the positioning plate 1, thereby opening the gap inside the positioning plate 1. The packaging object in the new material is placed in the inner wall of the positioning plate 1, so that the positioning plate 1 positions the packaging object. Then, the insert plate 33 is moved downward and inserted into the inner wall of the positioning plate 1, so that the insert plate 33 positions the packaging object.

[0041] Secondly, when the present invention applies extrusion force, the positioning plate 1 supports the mounting bracket 31, which in turn supports the controller 32. The controller 32 starts the reduction motor 30, which drives the screw 28 to rotate. The screw 28 rotates on the inner wall of the guide frame 29. At the same time, the screw 28 drives the sleeve plate 27 to move longitudinally downward under the action of the thread meshing force. The sleeve plate 27 slides along the inner wall of the guide frame 29, and the sleeve plate 27 drives the inclined pressure rod 2 to move longitudinally downward.

[0042] Simultaneously, when the invention applies pressure from the top, the inclined pressure rod 2 drives the first pressure sensor 7 to tilt downwards longitudinally, the first pressure sensor 7 drives the top pressure block 3 to tilt downwards longitudinally, and the top pressure block 3 drives the two positioning blocks 6 to tilt downwards longitudinally. In this way, the top pressure block 3 and the two positioning blocks 6 all move downwards longitudinally according to a specified tilt angle. The top pressure block 3 and the two positioning blocks 6 simultaneously apply longitudinal downward pressure to the top corner of the packaging, and the inclined pressure rod 2 presses against the sensing end of the first pressure sensor 7, and the first pressure sensor 7 senses the applied pressure value.

[0043] Simultaneously, when the present invention applies pressure in the middle, when the inclined pressure rod 2 moves longitudinally downward, the inclined pressure rod 2 drives the inclined frame 8 to move longitudinally downward, the inclined frame 8 drives the inclined column 9 to move longitudinally downward, the inclined column 9 causes the sleeve block 10 to move longitudinally downward, and the sleeve block 10 slides along the inner wall of the inclined column 9. At the same time, the sleeve block 10 slides along the inner wall of the inclined frame 8. In this way, the sleeve block 10 pulls the top of the linkage rope 11, the linkage rope 11 slides on the outer wall of the arc block 12, and the linkage rope 11 slides in the limiting gap of the two limiting sleeves 13. The positioning plate 1 supports the inclined sleeve strip 19, the inclined sleeve strip 19 supports the support strip 14, the support strip 14 supports the two limiting sleeves 13, and provides stable support force to the two limiting sleeves 13. In this way, the linkage rope 11 slides along the inner wall of the inclined sleeve 19, and at the same time, the linkage rope 11 slides on the outer wall of the positioning post 20, and the linkage rope 11 slides between the two positioning sleeves 21. The bottom end of the linkage rope 11 pulls the linkage block 15 to move laterally and tilting upward. The linkage block 15 drives the horizontal inclined rod 16 to move laterally and tilting upward. The horizontal inclined rod 16 moves laterally and tilting upward along the inner wall of the inclined sleeve 19. The horizontal inclined rod 16 drives the second pressure sensor 17 to move laterally and tilting upward. The second pressure sensor 17 drives the middle pressure block 4 to move laterally and tilting upward synchronously according to the tilt angle. In this way, the middle pressure block 4 performs lateral compression detection on the middle corner of the package according to the tilt angle. The horizontal inclined rod 16 presses on the sensing end of the second pressure sensor 17, and the second pressure sensor 17 senses the applied pressure value.

[0044] Simultaneously, when the present invention applies pressure to the bottom, the inclined pressure rod 2 drives the frame strip 22 to move longitudinally downward at a specified tilt angle, the frame strip 22 drives the sliding rod 23 to move longitudinally upward at a specified tilt angle, and the sliding rod 23 slides along the inner wall of the frame strip 22 at the same time. The sliding rod 23 drives the pressure guide rod 24 to move longitudinally upward at a specified tilt angle, and the pressure guide rod 24 moves longitudinally upward along the inner wall of the inclined sleeve plate 25 at a specified tilt angle, thereby realizing the guiding operation of the pressure guide rod 24. The pressure guide rod 24 drives the third pressure sensor 26 to move longitudinally upward at a specified tilt angle, the third pressure sensor 26 drives the longitudinal block 18 to move longitudinally upward at a specified tilt angle, and the longitudinal block 18 drives the bottom pressure block 5 to move longitudinally upward at a specified tilt angle. In this way, the bottom pressure block 5 simultaneously moves longitudinally upward at the bottom corner of the packaged item to perform pressure detection, and the pressure guide rod 24 presses on the sensing end of the third pressure sensor 26, and the third pressure sensor 26 senses the applied pressure value.

[0045] Finally, during the recording process, the pressure values ​​sensed by the first pressure sensor 7, the second pressure sensor 17, and the third pressure sensor 26 can all be recorded. The system also checks for deformation at the top corner of the packaging, the middle corner of the packaging, and the bottom corner of the packaging.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
