Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging box detection, and in particular to a detection device for packaging box defect detection. BACKGROUND

[0002] At present, many articles in daily life need to be packaged by using packaging boxes, and the types and styles of packaging boxes are relatively various, and generally, the packaging boxes are mainly in the form of cubes and cuboids. Before being put into the market, the packaging boxes need to be detected for multiple times to ensure that the performance indicators of the packaging boxes after being put into the market meet the standards and the quality of the packaging boxes is ensured.

[0003] When the packaging boxes are detected, the patterns and texts on the packaging boxes, the surface quality, the thickness uniformity and the tear resistance of the packaging boxes need to be detected, and in particular, the tear resistance of the packaging boxes. When the tear resistance of the packaging boxes is detected, the common tear resistance detection methods include a tear propagation test method and a pendulum impact test method.

[0004] The direct tensile test method is as follows: firstly, a small part of a sample is taken from a packaging box, and a notch is cut on the sample. The sample is installed on a fixing device of a pendulum impact testing machine, so that the notch position of the sample is located directly below an impact point, and the height of the pendulum is adjusted to a specified value. The pendulum is released, and according to the mass of the pendulum, the release height and the energy loss after impact and other parameters, the energy absorbed by the sample can be calculated, so as to indirectly reflect the tear resistance of the packaging box material.

[0005] The tear propagation test method is as follows: a small opening with a specific length and shape is accurately cut on a test piece to be detected, and the test piece is installed on a clamp of a tear propagation testing machine, so that the installation position of the test piece is accurate. Then, the testing machine pulls the test piece to be detected, and records the force value and the tear propagation distance in real time. According to the recorded data, a tear resistance curve is drawn to comprehensively evaluate the tear resistance of the packaging box material.

[0006] When the tear resistance is tested by the above two test methods, only the tear resistance of the packaging box material is tested, and it is not easy to accurately show the tear resistance of the packaging box in the use process. For example, when the packaging box is used to package a wine bottle, the packaging box is relatively heavy when it contains the wine bottle, and consumers often hold the packaging box by the bottom with both hands. When the packaging box is carried, the consumer needs to hold one ear to lift one side of the packaging box, put his hand into the bottom of the packaging box, hold the other ear to lift the other side of the packaging box, and put his hand into the bottom of the packaging box. In the process of lifting the packaging box, the folding part of the ear of the packaging box is easy to tear, and this scene is the most common scene of rupture in daily use. However, the above two test methods cannot easily show the tear resistance of the folding part of the ear, and therefore, it is not easy to obtain the accurate tear resistance of the packaging box when it is used to package heavy objects such as wine bottles. Therefore, it needs to be improved. SUMMARY

[0007] In order to obtain the accurate tear resistance of the packaging box under the working condition when it is used as a wine bottle package, so as to facilitate the accurate judgment of the carrying capacity and quality of the packaging box, the application provides a detection device for packaging box defect detection.

[0008] The detection device for packaging box defect detection provided by the application adopts the following technical scheme:

[0009] A detection device for packaging box defect detection, comprising a rack and a mounting table provided on the rack, the mounting table is used for placing the packaging box, the rack is provided with a detection assembly for detecting the tear of the ear edge of the packaging box, the mounting table is provided with a limiting block, the limiting block is provided with two groups, the side walls of the two groups of limiting blocks close to each other are movably attached to the outer peripheral wall of the packaging box; the detection assembly comprises a mounting block provided on the rack in a lifting manner, a clamping piece provided on the mounting block, and an adjusting piece for adjusting the lifting of the clamping piece, the clamping piece comprises two clamping blocks that move close to each other, a cavity is left between the two clamping blocks for placing the ear edge, the clamping block is rotatably provided on the mounting block, and a tension sensor is provided on the clamping block; when the mounting block rises, the clamping block slides towards the center of the packaging box; the clamping piece is provided with two groups, the two groups of clamping pieces are arranged opposite to each other, the extension directions of the two groups of clamping pieces are perpendicular to the extension directions of the two groups of limiting blocks; the mounting table is slidingly provided on the rack, and a limiting piece is further provided on the mounting block to limit the sliding of the mounting table.

[0010] By adopting the above technical scheme, when the tear resistance of the packaging box is detected, first of all, the technician adds a standard mass of weight into the packaging box, and places the packaging box on the mounting table, then the clamping block on one side of the packaging box is clamped, and then the adjusting piece makes the mounting block rise, so that the packaging box on one side is lifted, because in actual situation, when the ear edge on one side is lifted, the ear edge will displace, so that the ear edge always maintains a vertical state, therefore, by rotating the clamping block and sliding the clamping block on the mounting block, during the lifting of the packaging box, the clamping block slides on the mounting block, so that the clamping block changes the angle with the change of the lifting height, thereby simulating the working condition of the packaging box during carrying the weight.

[0011] When short-distance moving is performed, for example, the packaging box filled with white wine is moved to another place, the related personnel usually do not adopt the holding mode, but adopt the mode of holding two ears to transport the packaging box for a short distance. At this time, the packaging box will shake with the movement of the related personnel, and the ears are prone to be broken or torn. In order to simulate this situation on the detection device, so as to detect the anti-tearing performance of the packaging box under this working condition, when the two ears are clamped and lifted, the mounting table slides under the action of the limiting block, so as to simulate the shaking when the related personnel walks. According to the change of the tension sensor on the clamping block and whether the ear is torn, the anti-tearing performance of the ear of the packaging box is judged.

[0012] Meanwhile, by arranging the limiting block whose extending direction is perpendicular to the extending direction of the clamping piece, when the two ears are clamped, the clamping direction of the clamping block is perpendicular to the movement direction of the packaging box, so that the shaking direction when the packaging box is moved is simulated more accurately.

The two groups of adjusting blocks correspond to the two groups of clamping pieces one by one, and the clamping block is rotatably arranged on the adjusting block. When the mounting block is lifted, the mounting block is also provided with a sliding piece for synchronously sliding adjustment of the clamping piece.

[0014] By adopting the above technical scheme, when the two groups of clamping blocks need to be slidingly adjusted, the adjusting screw is rotated, so as to drive the two groups of adjusting blocks to synchronously slide on the adjusting screw to approach or move away, so as to realize synchronous rotation adjustment of the two groups of clamping blocks, and simulate the rotation state when the two ears of the packaging box are synchronously lifted.

[0015] Optionally, the sliding piece comprises a sliding gear rotatably arranged on the mounting block, the rack is arranged on the rack, the sliding gear is engaged with the sliding rack, the adjusting bevel gear is coaxially arranged on the adjusting screw, the sliding bevel gear is coaxially arranged on the sliding gear, and the adjusting bevel gear is engaged with the sliding bevel gear.

[0018] By adopting the above technical scheme, when it is necessary to simulate the working state of carrying the packaging box when the personnel hold two ears, at this time the sliding cam rotates, and under the action of the sliding spring, the outer peripheral wall of the sliding cam is always attached to the sliding block. When the sliding cam rotates, the distance between the sliding cam and the sliding block changes, thereby driving the mounting table to slide. Since the mounting table is provided with the limiting block, the packaging box is driven to shake under the action of the limiting block, thereby simulating the shaking of the packaging box in the carrying process.

[0019] Optionally, the limiting member comprises a first rotating rod, a second rotating rod and a third rotating rod rotatably arranged on the frame, the first rotating rod is in transmission connection with the adjusting gear, the first rotating rod, the second rotating rod and the third rotating rod are arranged in sequence along the same axis direction, the sliding cam is coaxially arranged on the third rotating rod, the first rotating rod is in movable transmission connection with the second rotating rod, the second rotating rod is in movable transmission connection with the third rotating rod, the mounting block is further provided with a transmission member for transmitting the first rotating rod and the second rotating rod, the second rotating rod and the third rotating rod, and the gap between the first rotating rod and the second rotating rod corresponds to a group of clamping blocks, and the gap between the second rotating rod and the third rotating rod corresponds to another group of clamping blocks.

By arranging the first rotating rod, the second rotating rod and the third rotating rod, when it is necessary to rotate and adjust the sliding cam, the transmission member is arranged to transmit the first rotating rod, the second rotating rod and the third rotating rod, thereby realizing the rotation and adjustment of the sliding cam. The gap between the first rotating rod and the second rotating rod and the gap between the second rotating rod and the third rotating rod correspond to the two groups of clamping blocks respectively, so that when the two groups of clamping blocks clamp the ears, the transmission member is adjusted, thereby realizing the rotation and adjustment of the sliding cam.

[0021] Meanwhile, through the first rotating rod arranged in cooperation with the adjusting gear, in the process of lifting the two ear edges by clamping the mounting table, the first rotating rod is always driven to rotate by the same power source, so that the first rotating rod, the second rotating rod and the third rotating rod are driven to rotate the sliding cam only when the two ear edges are lifted by clamping, thereby achieving the sliding adjustment of the mounting table.

[0022] Optionally, the transmission member comprises a first abutting sleeve slidably arranged on the second rotating rod, the first abutting sleeve is movably abutted with the end side of the first rotating rod, the third rotating rod is slidably arranged with a second abutting sleeve, the second abutting sleeve is movably abutted with the end side of the second rotating rod, and the frame is further provided with an abutting member for slidingly adjusting the first abutting sleeve and the second abutting sleeve.

[0023] By adopting the above technical scheme, in the process of simulating the short-distance transportation of the packaging box, the first abutting sleeve and the second abutting sleeve arranged in cooperation with the sliding member are slidably adjusted by the abutting member, so that the first abutting sleeve is abutted with the end side of the first rotating rod, the first rotating rod drives the second rotating rod to rotate, the second abutting sleeve is abutted with the end side of the second rotating rod, so as to realize the rotation of the third rotating rod driven by the second rotating rod, and the synchronous rotation of the first rotating rod, the second rotating rod and the third rotating rod, thereby realizing the rotation adjustment of the sliding cam.

[0025] By adopting the above technical scheme, when the first abutting sleeve / second abutting sleeve needs to be slidably adjusted, the locking rod is slidably driven by rotating the abutting rod, and the end side of the locking rod is inclined, so that the first abutting sleeve is slid in the direction of the first rotating rod / the second abutting sleeve is slid in the direction of the second rotating rod during the abutting of the locking rod and the first abutting sleeve / second abutting sleeve, thereby realizing the rotation transmission of the first rotating rod and the second rotating rod / the second rotating rod and the third rotating rod.

[0026] Optionally, the end of the abutting rod away from the locking rod is rotationally provided with a movable block protruding from the surface of the rack, the adjusting block is elastically and slidably provided with a containing block, the containing block is slidably arranged on the adjusting block, the sliding direction of the containing block is consistent with the height direction of the rack, the clamping block is rotationally arranged on the containing block, and the mounting block is slidably provided with a displacement block on the side close to the rack, one end of the displacement block protrudes from the surface of the mounting block, the other end of the displacement block is inclined, the displacement slot is arranged on the movable block, the inner side wall of the displacement slot is matched with the inclined side of the displacement block, and the end of the displacement block protruding from the mounting block is matched with the movable block.

[0028] When two groups of clamping blocks respectively detect the clamping of two ears of the packaging box, the corresponding displacement block is ejected when the two groups of containing blocks descend relative to the mounting block when the mounting block ascends, the first abutting sleeve and the second abutting sleeve slide to the abutting position, and the first rotating shaft, the second rotating shaft and the third rotating shaft are synchronously rotated.

[0029] By adopting the above technical scheme, when the clamping of the two ears of the packaging box is detected, the corresponding displacement block is ejected when the two groups of containing blocks descend relative to the mounting block when the mounting block ascends, the displacement block abuts against the movable block, thereby driving the abutting rod to rotate, the locking rod at the other end of the abutting rod slides, the two locking rods abut against the first abutting sleeve and the second abutting sleeve, the first abutting sleeve and the second abutting sleeve slide to the abutting position, and the first rotating shaft, the second rotating shaft and the third rotating shaft are synchronously rotated, thereby driving the sliding cam to rotate when the mounting table ascends, the sliding of the sliding block is realized, and the sliding of the mounting table is realized, thereby simulating the shaking when the relevant personnel carry.

DETAILED DESCRIPTION

[0040] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 The present application is further described in detail.

[0041] The embodiment of the present application discloses a detection device for packaging box defect detection. Figure 1 The detection device for packaging box defect detection comprises a vertically fixed rack 1 and a mounting table 11 horizontally arranged on the rack 1, the mounting table 11 is used for placing a packaging box 12, a standard quality weight is placed in the packaging box 12, and limiting blocks 14 are fixedly connected on the packaging box 12, the two limiting blocks 14 are oppositely arranged, the extending directions of the two limiting blocks 14 are consistent with the width direction of the packaging box 12, and the rack 1 is further provided with a detection assembly 2 for performing anti-tearing detection on the ear edge 13 of the packaging box 12.

[0042] Referring to Figure 1 and Figure 2 The detection assembly 2 comprises a mounting block 21 in a lifting type arranged on the rack 1, a clamping piece 22 arranged on the mounting block 21 and an adjusting piece 23 for adjusting the lifting of the mounting block 21 and the clamping piece 22, the adjusting piece 23 in the present application is an adjusting motor 231, the adjusting motor 231 is fixed to the top of the rack 1 and the output end penetrates through the top wall of the rack 1 and is fixedly connected with the mounting block 21, the mounting block 21 is horizontally arranged, the clamping piece 22 is provided with two groups, and the two groups of clamping pieces 22 are symmetrically and slidingly arranged on the mounting block 21, each group of clamping pieces 22 comprises two clamping blocks 221 which are movably close to each other, a cavity for clamping the ear edge 13 is left between the two clamping blocks 221, and the two clamping blocks 221 are all rotationally connected with the mounting block 21, the rotation axis of the clamping block 221 is consistent with the width direction of the packaging box 12, and the mounting block 21 is further provided with a sliding piece 3 for synchronously slidingly adjusting the two groups of clamping blocks 221.

[0043] An adjusting screw 25 is rotatably connected to the mounting block 21. The rotation axis of the adjusting screw 25 is aligned with the length direction of the packaging box 12. An adjusting block 26 is threaded onto the adjusting screw 25. A clamping block 221 is rotatably connected to the adjusting block 26. In each set of clamping components 22, one clamping block 221 is relatively fixed to the adjusting block 26 and only rotates relative to the adjusting block 26. The other clamping block 221 is relatively slidably disposed on the adjusting block 26 and slides relative to the adjusting block 26 while rotating relative to the adjusting block 26. A telescopic cylinder is fixedly connected to each set of adjusting blocks 26. The output end of the telescopic cylinder is fixedly connected to one clamping block 221. There are two sets of adjusting blocks 26, symmetrically arranged at both ends of the adjusting screw 25. Both ends of the adjusting screw 25 have external threads with the same pitch but opposite threads. (Refer to...) Figure 2 and Figure 3 The sliding component 3 includes a sliding gear 31 rotatably connected to the mounting block 21. The rotation axis of the sliding gear 31 is consistent with the width direction of the packaging box 12. A sliding rack 32 is fixedly connected to the frame 1. The sliding gear 31 meshes with the sliding rack 32. An adjusting bevel gear 33 is coaxially fixedly connected to the axis of the sliding gear 31. A sliding bevel gear 34 is coaxially provided on the adjusting screw 25. The adjusting bevel gear 33 meshes with the sliding bevel gear 34.

[0044] Therefore, when the mounting platform 11 is raised and lowered, causing the ear edges 13 of the packaging box 12 to be raised and lowered, the sliding rack 32 on the frame 1 does not shift. When the mounting platform 11 is raised and lowered, the sliding rack 32 drives the sliding gear 31 to rotate, the sliding gear 31 drives the sliding bevel gear 34 to rotate, the sliding bevel gear 34 drives the adjusting bevel gear 33 to rotate, thereby driving the adjusting screw 25 to rotate. Thus, when the adjusting component 23 drives the mounting platform 11 to be raised and lowered, it drives the two clamping blocks 221 to slide closer or further away synchronously. During the raising and lowering of the mounting platform 11, the clamping blocks 221 are automatically driven to slide and rotate, which facilitates the synchronous clamping and lifting of the two ear edges 13 of the packaging box 12 and the tear resistance test.

[0045] Meanwhile, in the short distance carrying, for example, the short distance of the full liquor packaging box 12 is moved, the relevant personnel often do not use the way of holding, using the two ears 13 to hold the packaging box 12 short distance transportation, at this time in the process of transportation, the packaging box 12 will be shaken with the movement of the relevant personnel, at this time the ear 13 is easy to produce fracture or tear.

[0046] Meanwhile, for different lengths of packaging box 12, the angle of the hands of the personnel is different when lifting the two ears 13, for example, when carrying the packaging box 12 with small length, the hands of the personnel hold the ears 13 and turn outward, and when carrying the packaging box 12 with small length, the hands of the personnel hold the ears 13 and turn inward. Therefore, in order to better simulate this use scenario, the sliding bevel gear 34 is provided with two groups, and the two groups of sliding bevel gears 34 are relatively symmetrically arranged, the tooth grooves of the two groups of sliding bevel gears 34 are opposite, and the sleeve is fixedly connected between the two groups of sliding bevel gears 34, the sleeve is slidingly arranged on the adjusting screw 25, the adjusting bevel gear 33 is located between the two groups of sliding bevel gears 34, and the two groups of sliding bevel gears 34 are selectively engaged with the adjusting bevel gear 33, so that when one of the two groups of sliding bevel gears 34 is engaged with the adjusting bevel gear 33, the two groups of clamping blocks 221 are away from each other when the installation table 11 rises, and when the other group of sliding bevel gears 34 is engaged with the adjusting bevel gear 33, the two groups of clamping blocks 221 are close to each other when the installation table 11 rises, so as to simulate two different carrying modes.
