Description

Technical Field

[0001] The invention relates to the technical field of EPE pearl cotton detection, in particular to an EPE pearl cotton product performance detection device. Background Art

[0002] EPE pearl cotton is a lightweight, flexible material with cushioning properties. EPE pearl cotton is usually processed into square packaging boxes. It is widely used in the protection of electronic products, fragile items and other items during transportation and handling. In order to ensure the protective effect of the packaging box during use, it is usually necessary to test the impact resistance and compression resistance of the packaging box.

[0003] When performing performance testing on packaging boxes, the packaging box is usually first clamped and fixed by a clamping device, and then fragile items are manually placed in the packaging box. Finally, the four sides of the packaging box are impacted and pressured by an impact device and a pressure device respectively, and the fragile items in the packaging box are observed to see if they are damaged, thereby realizing the testing of the packaging box's impact resistance and pressure resistance.

[0004] The following problems exist in the existing performance testing of packaging boxes: 1. Since performance testing is required on all four sides of the packaging box, it is currently impossible to perform impact resistance and compression resistance testing on the packaging box at the same time. In addition, when performing performance testing on different sides of the packaging box, the position of the testing device needs to be adjusted, which increases the complexity of the performance testing of the packaging box and thus reduces the efficiency of the performance testing of the packaging box; 2.

[0028] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0029] See Figure 1 , an EPE pearl cotton product performance testing equipment, including a base 1, a clamping device 2 is installed on the upper end of the base 1, a detection device 3 is installed on the clamping device 2, an alarm device 4 is distributed above the clamping device 2, and the alarm device 4 is installed on the external free end.

[0030] The present invention is used to perform performance testing on a packaging box made of EPE pearl cotton, and the present invention can simultaneously test the impact resistance and pressure resistance of the packaging box, thereby increasing the performance testing efficiency of the packaging box; specifically, first, the packaging box is placed in the clamping device 2 with the opening facing upward, and the clamping device 2 is controlled to clamp and fix the packaging box, then the alarm device 4 is controlled to extend into the packaging box and fit onto the inner wall of the packaging box, and finally, the detection device 3 is started to perform impact testing and pressure testing on the packaging box at the same time.

[0031] When the impact resistance and pressure resistance of the packaging box are tested, if the alarm device 4 emits a buzzer alarm, the packaging box performance test fails, otherwise, it passes. Finally, the clamping device 2 is controlled to release the packaging box, and the alarm device 4 is controlled to return to the initial position, so that the packaging box can be taken out after the performance test is completed.

[0032] See Figure 1-Figure 3 The clamping device 2 includes a fixed column 21 fixedly installed in the middle of the upper end of the base 1, and two No. 1 synchronization units 22 are installed on the fixed column 21. The upper end of the fixed column 21 is respectively slid left and right and forward and backward with symmetrically arranged clamping plates 23 through the two No. 1 synchronization units 22. The No. 1 synchronization unit 22 is used to synchronously adjust the positions of the two clamping plates 23.

[0033] It should be noted that the No. 1 synchronization unit 22 includes a No. 1 double-headed screw and a No. 2 motor. The No. 1 double-headed screw is provided with two threaded sections with opposite rotation directions, and the No. 1 double-headed screws corresponding to the two No. 1 synchronization units 22 are arranged vertically and staggered up and down. The two clamping plates 23 corresponding to the No. 1 synchronization unit 22 are connected to the threaded sections corresponding to the No. 1 double-headed screw by threaded cooperation. One end of the No. 1 double-headed screw is fixedly connected to the output shaft of the No. 2 motor, and the No. 2 motor is fixedly installed in the fixed column 21. By starting the No. 2 motor to drive the No. 1 double-headed screw to rotate, the No. 1 double-headed screw drives its corresponding two clamping plates 23 to move synchronously.

[0034] The clamping device 2 is used to clamp and fix the packaging box; specifically, the packaging box is placed on the fixed column 21, and then the two No. 1 synchronization units 22 are controlled respectively to drive the corresponding two clamping plates 23 to move towards each other, so that multiple clamping plates 23 can simultaneously clamp and fix the front and back ends and left and right ends of the packaging box.

[0035] See Figure 1The detection device 3 includes a connecting sleeve 31 that is rotatably sleeved on the outer side of the upper part of the fixed column 21. A rotating plate 32 is fixedly sleeved on the outer side of the connecting sleeve 31. Two symmetrically arranged synchronous plates 34 are installed on the upper end of the rotating plate 32 for sliding left and right through multiple return springs 33. A pressure roller 36 is installed on the upper end of one of the synchronous plates 34 through a pressure unit 35. The pressure unit 35 is used to drive the pressure roller 36 to apply a certain pressure to the packaging box. A plurality of impact blocks 38 evenly arranged front and back are installed on the upper end of the other synchronous plate 34 through an impact unit 37. The impact unit 37 is used to drive the impact block 38 to impact the packaging box.

[0036] See Figure 1 、 Figure 3 and Figure 6 , multiple clamping plates 23 are equipped with matching units 24, and the matching units 24 are used to synchronously adjust the position of the synchronization plate 34 according to the position of the clamping plate 23. The left end of the impact block 38 is set to a frustum structure, and the surface area of ​​the multiple impact blocks 38 increases successively from front to back.

[0037] See Figure 2 A gear ring 311 is provided on the lower fixed sleeve outside the connecting sleeve 31, and a gear 312 is meshedly installed on the outer side of the gear ring 311, and the lower end of the gear 312 is fixedly connected to the output shaft of the No. 1 motor 313 fixedly installed on the upper end of the base 1.

[0038] The detection device 3 is used to perform impact detection and pressure detection on the packaging box at the same time; specifically, after the clamping plate 23 clamps and fixes the packaging box, the clamping plate 23 synchronously adjusts the positions of the two synchronization plates 34 through the matching unit 24, so that the two synchronization plates 34 respectively drive the corresponding pressure rollers 36 and impact blocks 38 to move to the corresponding positions of the packaging box through the pressure unit 35 and the impact unit 37, and then control the pressure unit 35 to make the pressure roller 36 apply a certain pressure to the left end of the packaging box, and control the pressure unit 35 to drive the pressure roller 36 to move back and forth, so as to realize the pressure resistance performance test of the packaging box.

[0039] At the same time, the impact unit 37 is controlled to drive the impact block 38 to move back and forth. When the impact block 38 moves to the corresponding position of the packaging box, the conical structure of the impact block 38 can make the impact block 38 elastically fit on the packaging box under the action of the impact unit 37, and select the corresponding impact block 38 according to the area where the impact force is applied to the packaging box as needed, so that the impact unit 37 drives the corresponding impact block 38 to continuously impact the right end of the packaging box, thereby realizing the impact resistance performance test of the packaging box, and then realizing the impact resistance and pressure resistance performance test of the packaging box, thereby increasing the performance test efficiency of the packaging box.

[0040] Control motor No. 1 313 to drive the ring gear 311 to rotate 90 degrees through gear 312, so that the ring gear 311 finally drives the pressure roller 36 and the impact block 38 to rotate 90 degrees through the connecting sleeve 31 and the rotating plate 32, so that the pressure roller 36 and the impact block 38 can perform performance tests on the four sides of the packaging box, and when the rotating plate 32 rotates 90 degrees each time, the matching unit 24 corresponding to its rotation position can synchronously adjust the position of the synchronization plate 34 according to the position of the corresponding clamping plate 23, so that the pressure roller 36 and the impact block 38 can be moved to the corresponding position of the packaging box, and there is no need to adjust the position of the pressure roller 36 and the impact block 38, so that the performance test operation of the packaging box is simple, and the performance test efficiency of the packaging box is further increased.

[0041] See Figure 1 and Figure 3 The mating unit 24 includes a U-shaped plate 241 fixedly mounted on the lower end of the clamping plate 23, and the U-shaped plate 241 is radially slidably connected to the fixed column 21. A mating plate 242 with a trapezoidal structure is fixedly mounted on the upper end of the vertical end of the U-shaped plate 241 away from the fixed column 21. The two synchronous plates 34 are fixedly mounted with L-shaped round rods 345 on the back sides of the two synchronous plates 34, and the horizontal section of the round rod 345 slides left and right through the rotating plate 32. The vertical section of the round rod 345 is used to cooperate with the trapezoidal structure of the mating plate 242 to drive the synchronous plate 34 to move.

[0042] The mating unit 24 is used to synchronously adjust the position of the synchronization plate 34 according to the position of the clamping plate 23; specifically, when the position of the clamping plate 23 is adjusted, the clamping plate 23 drives the mating plate 242 to move synchronously through the U-shaped plate 241. When the rotating plate 32 is in the initial position, the two mating plates 242 arranged on the left and right can drive the two synchronization plates 34 to move toward each other through the round rod 345 and compress the reset spring 33 to achieve synchronous position adjustment of the synchronization plate 34. When the rotating plate 32 rotates, the rotating plate 32 drives the round rod 345 to rotate synchronously and separate from the two mating plates 242 arranged on the left and right, so that the synchronization plate 34 drives the round rod 345 to return to the initial position under the action of the reset spring 33.

[0043] When the rotating plate 32 drives the round rod 345 to rotate to the corresponding position of the next adjacent matching plate 242, the trapezoidal structure of the matching plate 242 and the vertical section of the round rod 345 cooperate to drive the two synchronous plates 34 to move toward each other, so that the synchronous plates 34 can move synchronously according to the position of the clamping plate 23. Then, when inspecting different surfaces of the packaging box, the synchronous plates 34 can respectively drive the corresponding pressure rollers 36 and impact blocks 38 to move to the corresponding positions of the packaging box through the pressure units 35 and the impact units 37. There is no need to adjust the positions of the pressure rollers 36 and the impact blocks 38, which makes the performance inspection of the packaging box simple to operate, and further increases the efficiency of the performance inspection of the packaging box.

[0044] participate Figure 2 、 Figure 4 and Figure 5 The pressurizing unit 35 includes an electric slider assembly 351 installed on the upper end of the synchronization plate 34, a connecting plate 352 is installed on the upper end of the electric slider assembly 351, an adjusting plate 353 is slidably installed on the upper end of the connecting plate 352, an adjusting screw 354 is threadedly connected to the lower end of the adjusting plate 353, and the adjusting screw 354 and the connecting plate 352 are rotatably connected, and the side of the adjusting plate 353 close to the fixed column 21 is hinged with a pressurizing plate 356 through two connecting rods 355 arranged up and down, and the right end of the pressurizing plate 356 is installed with a U-shaped frame 358 through a plurality of pressurizing spring rods 357 evenly arranged up and down, and the pressurizing roller 36 is rotatably installed in the U-shaped frame 358.

[0045] The pressure unit 35 is used to drive the pressure roller 36 to apply a certain pressure to the packaging box; specifically, by screwing the adjusting screw 354, the adjusting plate 353 is driven to move toward the packaging box, so that the adjusting plate 353 finally drives the U-shaped frame 358 and the pressure roller 36 to move toward the packaging box through the connecting rod 355 and the pressure plate 356. At the same time, the pressure roller 36 compresses the pressure spring rod 357 under the blocking action of the packaging box, and then the compression amount of the pressure spring rod 357 is used to adjust the pressure applied by the pressure roller 36 on the packaging box. The No. 1 electric slider assembly 351 is started and finally drives the pressure roller 36 to move back and forth according to the size of the test surface of the packaging box through the connecting plate 352, thereby realizing the pressure resistance performance test of the packaging box.

[0046] See Figure 5 and Figure 6 The cam 354 is provided with an L-shaped structure, and the left side of the rear end of the horizontal section of the cam 354 is provided with an inclined surface, the lower connecting rod 355 is fixedly connected to the adjusting plate 353, and the upper connecting rod 355 and the pressure plate 356 are connected to the pressure plate 356 for sliding movement up and down. The left end of the upper connecting rod 355 slides left and right through the adjusting plate 353 and is connected to the adjusting plate 353 with a top spring 350. A plurality of locking holes are provided on the side of the upper connecting rod 355 close to the locking spring rod 359, which are evenly arranged along the length direction of the connecting rod 355. The locking holes are used to cooperate with the locking spring rod 359 to lock the upper connecting rod 355.

[0047] See Figure 5An L-shaped toggle plate 341 is fixedly installed on one end of the upper side of the synchronous plate 34 on which the pressure unit 35 is installed, close to the locking spring rod 359. The rear end of the horizontal section of the toggle plate 341 is set as an inclined surface. The inclined surface of the toggle plate 341 is used to drive the upper connecting rod 355 to move to the right. An L-shaped unlocking plate 342 is fixedly installed in the middle of the other end of the upper side of the synchronous plate 34. The unlocking plate 342 is used to drive the locking spring rod 359 to move out of the locking hole of the connecting rod 355.

[0048] When pressure testing is performed on the packaging box, the No. 1 electric slider assembly 351 finally drives the pressure roller 36 to move back and forth between the toggle plate 341 and the unlocking plate 342 through the connecting plate 352. When the pressure plate 356 needs to apply uneven pressure to the packaging box, the No. 1 electric slider assembly 351 is controlled to drive the upper connecting rod 355 to the corresponding position of the toggle plate 341 through the connecting plate 352 and the adjustment plate 353, so that the connecting rod 355 moves toward the direction close to the packaging box under the action of the inclined surface of the horizontal section of the toggle plate 341 and compresses the extension spring 350. The inclined surface set on the left side of the rear end of the horizontal section of the locking spring rod 359 does not affect the movement of the connecting rod 355 toward the packaging box, and the locking spring rod 359 can lock the connecting rod 355, so that the connecting rod 355 will not move away from the packaging box under the action of the extension spring 350.

[0049] The moving distance of the upper connecting rod 355 toward the packaging box can be controlled by controlling the moving distance of the upper connecting rod 355 relative to the inclined surface of the horizontal section of the toggle plate 341, and the hinge of the upper connecting rod 355 and the pressure plate 356 and the pressure plate 356 are connected to slide up and down, so that the upper end of the pressure plate 356 is deflected in the direction close to the packaging box under the action of the upper connecting rod 355, and then the pressure roller 36 applies pressure to the packaging box in an inclined posture, so that the pressure roller 36 applies uneven pressure to the packaging box from top to bottom, and thus can simulate the force conditions of the packaging box during actual use, thereby increasing the accuracy of the detection results.

[0050] By controlling the No. 1 electric slider assembly 351 to drive the upper connecting rod 355 to move to the corresponding position of the unlocking plate 342 through the connecting plate 352 and the adjusting plate 353, the horizontal section of the unlocking plate 342 can drive the locking spring rod 359 to move out of the locking hole of the connecting rod 355, thereby releasing the lock on the connecting rod 355, and allowing the connecting rod 355 to return to its initial position away from the packaging box under the action of the extension spring 350, thereby restoring the pressure roller 36 to a vertical state.

[0051] See Figure 6The impact unit 37 includes a No. 2 electric slider assembly 371 installed on the upper end of the corresponding synchronization plate 34, a vertical plate 372 is installed on the upper end of the No. 2 electric slider assembly 371, and a plurality of impact spring rods 373 evenly arranged along the length direction of the vertical plate 372 are slidably installed on the vertical plate 372. The impact spring rod 373 is fixedly connected to its corresponding impact block 38 at one end close to the fixed column 21, and the multiple impact spring rods 373 are slidably sleeved with an impact plate 374 at one end away from the fixed column 21. The impact plate 374 is connected to the vertical plate 372 through two symmetrically arranged connecting spring rods 375.

[0052] See Figure 6 and Figure 7 A circular hole is provided on the upper side of the impact spring rod 373, and a mounting hole is provided at the position corresponding to the circular hole on the upper end of the impact plate 374, and a pin 376 is detachably installed in the mounting hole.

[0053] See Figure 7 A matching spring rod 377 is fixedly installed in the middle of the lower end of the impact plate 374, and the front side of the lower end of the matching spring rod 377 is set to an inclined surface, and a sliding plate 343 is installed to slide left and right on the right side of the upper end of the corresponding synchronous plate 34. The lower end of the sliding plate 343 is threadedly connected to a threaded rod 346, and the threaded rod 346 and the synchronous plate 34 are rotatably connected. A plurality of toggle blocks 344 are fixedly installed on the upper end of the sliding plate 343 away from the fixed column 21, and one side of the toggle block 344 is set to an inclined surface for driving the matching spring rod 377 to move to the right.

[0054] The impact unit 37 is used to drive the impact block 38 to impact the packaging box; specifically, first, according to the area of ​​the packaging box that needs to be impacted, the pin 376 is inserted into the mounting hole of the impact plate 374 and the circular hole of the impact spring rod 373 corresponding to the impact block 38, and the No. 2 electric slider assembly 371 is controlled to drive the vertical plate 372 to move back and forth. The vertical plate 372 drives the impact plate 374 to move through the connecting spring rod 375. At the same time, the vertical plate 372 drives the impact block 38 to move through the impact spring rod 373. When the impact block 38 moves to the corresponding position of the packaging box, the frustum structure of the impact block 38 can make the impact block 38 elastically fit on the packaging box under the action of the impact spring rod 373.

[0055] When the impact plate 374 drives the matching spring rod 377 to move in the direction away from the inclined surface of the matching spring rod 377, the matching spring rod 377 first drives the impact plate 374 to move in the direction away from the packaging box under the action of the inclined surface of the toggle block 344, so that the impact plate 374 drives the corresponding impact block 38 to move in the direction away from the packaging box through the pin 376 and the impact spring rod 373, and then the impact plate 374 quickly returns to its initial position under the action of the connecting spring rod 375 and the impact spring rod 373 locked by the pin 376, so that the impact block 38 can impact the packaging box, and the toggle block 344 is provided with multiple, so that the impact block 38 can continuously impact the packaging box, and by selecting impact blocks 38 with different surface areas, impact tests on different impact areas of the packaging box are realized, thereby increasing the accuracy of impact detection on the packaging box.

[0056] The position of the sliding plate 343 can be adjusted by screwing the threaded rod 346, thereby achieving the adjustment of the impact force of the impact block 38. When the impact plate 374 drives the matching spring rod 377 to move toward the direction close to the inclined surface of the toggle block 314, the inclined surface of the matching spring rod 377 can cooperate with the toggle block 344 to compress the telescopic end of the matching spring rod 377, thereby preventing the matching spring rod 377 from hindering the movement of the impact plate 374.

[0057] See Figure 1 and Figure 8 The alarm device 4 includes a circular plate 42 mounted on the upper end, on which two No. 2 synchronization units 43 are mounted. The lower end of the circular plate 42 is symmetrically slidably mounted left and right and front and back through the two No. 2 synchronization units 43. The electric push rod 41 is at the external free end, and the circular plate 42 is fixedly mounted on the lower end of the electric push rod 41. The lower ends of the multiple insertion plates 44 on the opposite sides are slidably mounted with a fitting plate 46 through a plurality of fitting spring rods 45. A buzzer alarm 47 is installed on the side of the insertion plate 44 close to the fitting plate 46.

[0058] It should be noted that the No. 2 synchronization unit 43 includes a No. 2 double-headed screw and a No. 3 motor. The No. 2 double-headed screw is provided with two threaded sections with opposite rotation directions, and the No. 2 double-headed screws corresponding to the two No. 2 synchronization units 43 are arranged vertically and staggered up and down. The two insert plates 44 corresponding to the No. 2 synchronization unit 43 are connected to the threaded sections corresponding to the No. 2 double-headed screw by threaded cooperation. One end of the No. 2 double-headed screw is fixedly connected to the output shaft of the No. 3 motor, and the No. 3 motor is fixedly installed in the circular plate 42. By starting the No. 3 motor to drive the No. 2 double-headed screw to rotate, the No. 2 double-headed screw drives its corresponding two insert plates 44 to move synchronously.

[0059] The alarm device 4 is used to alarm when the performance of the packaging box is unqualified; specifically, the electric push rod 41 is controlled to drive the insertion plate 44 to insert into the packaging box through the circular plate 42, and then the second synchronization unit 43 is controlled to finally drive the bonding plate 46 to fit the inner wall of the packaging box through the insertion plate 44, and the distance between the bonding plate 46 and the buzzer alarm 47 is controlled according to the performance of the packaging box. When the performance of the packaging box is unqualified, the inner wall of the packaging box can drive the bonding plate 46 to move toward the direction close to the buzzer alarm 47 and trigger the buzzer alarm 47, so that the buzzer alarm 47 alarms. If the buzzer alarm 47 does not alarm, the test result is qualified.

[0060] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
