Description

Technical Field

[0001] The invention relates to the technical field of corrugated cardboard measurement, in particular to a tear-off box body and a height measuring device for corrugated cardboard used in production. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of corrugated core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and cardboard and the structure of the box itself.

[0003] Chinese patent publication number CN110360936A discloses a paper height measurement system for corrugated cardboard production, comprising a height measurement module, a corrugated cardboard information library, and a production management module. The height measurement module is used to measure the height of a corrugated cardboard stack and transmit the measurement results to the production management module; the corrugated cardboard information library is used to store basic information about the corrugated cardboard; and the system is used to calculate the number of sheets in a stack of corrugated cardboard. The present invention relates to a paper height measurement system for corrugated cardboard production. This system can automatically calculate the overall height of a stack of corrugated cardboard based on data measured by a height sensor. Simultaneously, the production management module can directly calculate the number of sheets in a stack based on the measured height information and stored thickness information. This eliminates the time-consuming and labor-intensive manual measurement process, which can lead to significant errors.

[0016] The present invention provides a height measuring device for a tear-off box body and a corrugated cardboard for production through improvement. Compared with the prior art, the present invention has the following improvements and advantages:

[0017] Firstly, the corrugated cardboard of the present invention is placed on the receiving platform. Whenever a corrugated cardboard is placed, the two transverse abutting components will move closer to each other to perform transverse alignment of the corrugated cardboard.

[0018] Then, the two vertical plates move closer to each other to align the corrugated cardboard longitudinally. After the alignment is completed, the first electric telescopic rod controls the sleeve rod to move downward, thereby driving the connecting column to move the pressing plate downward. The pressing plate contacts the corrugated cardboard, thereby improving the stability of the corrugated cardboard stacking and simultaneously realizing the alignment of the four sides of the corrugated cardboard, providing convenience for the subsequent packaging of the corrugated cardboard.

[0019] Secondly, the present invention can receive laser light through a laser receiving plate to measure distance data, so that the present invention can accurately determine the height data of each corrugated paper, and can also measure the overall height of multiple corrugated papers after stacking, thereby improving measurement efficiency.

[0020] Third: After the present invention completes the measurement and alignment of the corrugated cardboard each time, the connecting plate will drive the first electric telescopic rod, sleeve rod, pressure plate and other measuring tools to move up a specified distance, so that the distance the connecting plate moves down each time remains constant, without consuming a lot of time, thereby improving efficiency.

[0021] Fourthly, in addition to the quantitative value of each upward movement, the distance of each upward movement of the connecting plate in the present invention will also increase or decrease by a certain distance, the value of which is f. The value of f depends on the point where the laser irradiates between ac. For example, when the laser irradiation point is directly between ab, the height of the corrugated cardboard increases within the error range, and the value of f is the value of the increased part of the corrugated cardboard. Therefore, when measuring the next corrugated cardboard, and the laser point is directly at point b, the corrugated cardboard is a precise and qualified product, thereby eliminating the influence of the error value on the stacking and achieving accurate measurement of the height of each corrugated cardboard.

[0022] Fifth: In the present invention, when it is detected that the corrugated cardboard is unqualified, one of the vertical plates moves away from the other vertical plate, and the push plate in the other vertical plate moves linearly under the action of the second electric telescopic rod, so that the push plate pushes the unqualified corrugated cardboard out of the range of the receiving platform. During this period, multiple blocking plates are in a state of resistance to the corrugated cardboard to ensure the stacking of the corrugated cardboard. When pushing out the unqualified corrugated cardboard, the push plate will drive the extension plate to move synchronously, so that the extension plate can push the blocking plate that is flush with the height of the unqualified corrugated cardboard. Under the action of the guide surface, the blocking plate will be out of the state of resistance to the unqualified corrugated cardboard, thereby facilitating the pushing out of the unqualified corrugated cardboard.

[0038] Example

[0039] like Figures 1-8 As shown, the present invention provides a tear-off box body and a height measuring device for corrugated cardboard for production, including a storage plate 1 and a receiving platform 2. The storage plate 1 is provided with side wall panels 101 on all four sides, and one end of the side wall panels 101 is fixedly connected to a top panel 102. A tear-off portion 103 is provided on the top panel 102, and anti-slip teeth 104 are further provided on the outer wall of the top panel 102. A notch 105 is provided on the inner wall of the side wall panel 101, and the anti-slip teeth 104 are snap-connected to the notch 105.

[0040] Specifically: when installing the tear box body, the anti-slip teeth 104 and the notch 105 are frictionally engaged to enhance the overall stability of the tear box body, and the tear portion 103 is pulled open, thereby dividing the top plate 102 into two, making it easier to open the tear box body, and the tear portion 103 is opened once, which plays an anti-theft role.

[0041] The top of the receiving platform 2 is used to stack corrugated cardboard, and the bottom of the receiving platform 2 is fixedly connected to the first two-way telescopic cylinder 201, and the bottom of the first two-way telescopic cylinder 201 is fixedly connected to the second two-way telescopic cylinder 202. Both ends of the first two-way telescopic cylinder 201 are fixedly connected to a horizontal conflict component, and both ends of the second two-way telescopic cylinder 202 are fixedly connected to a longitudinal conflict component. The longitudinal conflict component includes a vertical plate 3, which is used to conflict with the long side of the corrugated cardboard. The bottom of the vertical plate 3 is fixedly connected to a bracket plate 301, and the bottom of the bracket plate 301 is fixedly connected to the output shaft of the second two-way telescopic cylinder 202. The vertical plate 3 has an opening Slot 302, a screw rod 303 is rotatably connected in the slot 302, a motor 304 is fixedly connected to the top of the vertical plate 3, the output shaft of the motor 304 is fixedly connected to the screw rod 303, a connecting plate 305 is threadedly connected to the screw rod 303, a first electric telescopic rod 306 is fixedly connected to the connecting plate 305, a sleeve rod 307 is fixedly connected to the bottom of the first electric telescopic rod 306, a connecting column 308 is elastically connected in the sleeve rod 307, a pressure plate 309 is fixedly connected to the bottom of the connecting column 308, a laser emitter 310 is fixedly connected to the outer peripheral wall of the connecting column 308, and a laser receiving plate 311 is provided in the sleeve rod 307.

[0042] Specifically: the corrugated cardboard is placed on the receiving platform 2. Whenever a corrugated cardboard is placed, the two transverse abutment components will move closer to each other to perform transverse alignment of the corrugated cardboard;

[0043] Next, the two vertical plates 3 are brought closer to each other to align the corrugated cardboards longitudinally. After the alignment is completed, the first electric telescopic rod 306 controls the sleeve rod 307 to move downward, thereby the connecting column 308 drives the pressing plate 309 to move downward. The pressing plate 309 contacts the corrugated cardboards, thereby improving the stability of the corrugated cardboard stacking and simultaneously achieving the alignment of the four sides of the corrugated cardboards, providing convenience for the subsequent packaging of the corrugated cardboards.

[0044] Note: See Figure 6 The first electric telescopic rod 306 controls the downward movement of the sleeve rod 307 to a fixed distance. The fixed distance is the distance between point b and point d plus the distance between the top surface of the corrugated cardboard and the bottom surface of the pressing plate 309. The height of point d is consistent with the height of the laser emitter 310. When the sleeve rod 307 moves downward, the following situations will occur:

[0045] First: The direct point of the laser emitter 310 is at point b. At this time, the height of the single corrugated paper is at the most accurate value, which is a qualified product.

[0046] Second: The direct point of the laser emitter 310 is between point a and point b, and the height of the corrugated paper is within the error range, which is a qualified product;

[0047] Third: The direct point of the laser emitter 310 is higher than point a, and the height of the corrugated paper is higher than the normal value, which is an unqualified product;

[0048] Fourth: The direct point of the laser emitter 310 is between point c and point b, and the height of the corrugated paper is within the error range, which is a qualified product;

[0049] Fifth: The direct point of the laser emitter 310 is lower than point C, and the height of the corrugated paper is lower than the normal value, which is an unqualified product;

[0050] That is, only in the first, second, and fourth cases, the height of the corrugated paper is within a reasonable range and is a qualified product, and the laser receiving plate 311 can receive the laser to achieve distance data measurement, so that the present invention can accurately determine the height data of each corrugated paper, and can also measure the overall height of multiple corrugated papers after stacking, thereby improving measurement efficiency;

[0051] Among them, the motor 304 controls the rotation of the screw rod 303, thereby controlling the connection plate 305 to move up and down. Each time the alignment work and height measurement work of a corrugated cardboard are completed, the connection plate 305 is controlled to move up a specified distance, and at the same time the vertical plate 3 and the horizontal interference component are reset to facilitate the entry of the next corrugated cardboard. That is, each time the measurement and alignment work of the corrugated cardboard is completed, the connection plate 305 will drive the first electric telescopic rod 306, the sleeve rod 307, the pressing plate 309 and other measuring tools to move up a specified distance, so that the distance the connection plate 305 moves down each time remains constant, without consuming a lot of time, and improving efficiency.

[0052] It is worth noting that, in addition to the quantitative value of each upward movement of the connecting plate 305, the connecting plate 305 will also increase or decrease a certain distance, the value of which is f. The value of f depends on the point where the laser irradiates between ac. For example, when the laser irradiation point is directly between ab, the height of the corrugated cardboard increases within the error range, and the value of f is the value of the increased part of the corrugated cardboard. Therefore, when measuring the next corrugated cardboard, and the laser point is directly on point b, the corrugated cardboard is a precise and qualified product, thereby eliminating the influence of the error value on the stacking and achieving accurate measurement of the height of each corrugated cardboard.

[0053] Both sides of the connecting plate 305 are fixedly connected to the linkage frame 312, and the two sides of the vertical plate 3 are slidably connected to the push plates 313. One end of the two push plates 313 is commonly connected to the horizontal plate 314. The bottom of the linkage frame 312 is slidably connected to the top of the push plate 313. The side wall of the horizontal plate 314 is fixedly connected to the second electric telescopic rod 315, and the second electric telescopic rod 315 is slidably connected to the outer wall of the vertical plate 3.

[0054] A first slide 316 is fixedly connected to the bottom of the linkage frame 312, and a first sliding groove 317 is provided on the top of the push plate 313. The first slide 316 is slidably set in the first sliding groove 317. Two first limiting grooves 318 are symmetrically provided on the inner wall of the first sliding groove 317. Two first limiting bars 319 are symmetrically fixedly connected to the outer wall of the first slide 316. The first limiting bars 319 are slidably set in the first limiting grooves 318 on the corresponding sides.

[0055] A second slide is fixedly connected to the outer wall of the second electric telescopic rod 315, and a second slide groove 320 is provided on the outer wall of the vertical plate 3. The second slide is slidably set in the second slide groove 320. Two second limiting grooves are symmetrically provided on the inner wall of the second slide groove 320. Two second limiting bars are symmetrically fixedly connected to the outer wall of the second slide, and the second limiting bars are slidably set in the second limiting grooves on the corresponding sides.

[0056] The lateral interference component includes a base 4, a frame 401 is fixedly connected to the top of the base 4, a plurality of support plates 402 are slidably arranged on the frame 401, and the plurality of support plates 402 are stacked in sequence from top to bottom. A groove 403 is opened in the support plate 402, and a blocking plate 404 is elastically connected in the groove 403.

[0057] The inner walls on both sides of the frame 401 are fixedly connected with third sliding grooves 405 , and the outer walls on both sides of the support plate 402 are symmetrically fixedly connected with sliders 406 , which are slidably arranged in the third sliding grooves 405 .

[0058] The end of the push plate 313 is fixedly connected to the extension plate 407 , and arc-shaped guide surfaces 408 are provided on both sides of the blocking plate 404 .

[0059] Specifically, when a corrugated cardboard is detected to be unqualified, one of the risers 3 moves away from the other riser 3, and the push plate 313 in the other riser 3 moves linearly under the action of the second electric telescopic rod 315, so that the push plate 313 pushes the unqualified corrugated cardboard out of the range of the receiving platform 2. During this period, the multiple blocking plates 404 are in a state of resisting the corrugated cardboard to ensure the stacking of the corrugated cardboard;

[0060] Among them, when pushing out unqualified corrugated cardboard, the push plate 313 will drive the extension plate 407 to move synchronously, so that the extension plate 407 can push the blocking plate 404 that is flush with the height of the unqualified corrugated cardboard. Under the action of the guide surface 408, the blocking plate 404 will be out of the state of interference with the unqualified corrugated cardboard, thereby facilitating the pushing out of the unqualified corrugated cardboard.

[0061] The bottom of the second bidirectional telescopic cylinder 202 is fixedly connected to a support base.

[0062] A cushion block is provided at the bottom of the support seat.

[0063] Working principle: The corrugated cardboard is placed on the receiving platform 2. Whenever a corrugated cardboard is placed, the two horizontal abutment components will move closer to each other to align the corrugated cardboard horizontally;

[0064] Next, the two vertical plates 3 move closer to each other to align the corrugated cardboard longitudinally. After the alignment is completed, the first electric telescopic rod 306 controls the sleeve rod 307 to move downward, so that the connecting column 308 drives the pressing plate 309 to move downward. The pressing plate 309 contacts the corrugated cardboard, thereby improving the stability of the corrugated cardboard stacking and simultaneously achieving the alignment of the four sides of the corrugated cardboard, which facilitates the subsequent packaging of the corrugated cardboard. The laser receiving plate 311 can receive laser light to measure distance data, so that the present invention can accurately determine the height data of each corrugated cardboard, and can also measure the overall height of multiple corrugated cards after stacking, thereby improving measurement efficiency.

[0065] Among them, the motor 304 controls the rotation of the screw rod 303, thereby controlling the connection plate 305 to move up and down. Each time the alignment work and height measurement work of a corrugated cardboard are completed, the connection plate 305 is controlled to move up a specified distance, and at the same time the vertical plate 3 and the horizontal interference component are reset to facilitate the entry of the next corrugated cardboard. That is, each time the measurement and alignment work of the corrugated cardboard is completed, the connection plate 305 will drive the first electric telescopic rod 306, the sleeve rod 307, the pressing plate 309 and other measuring tools to move up a specified distance, so that the distance the connection plate 305 moves down each time remains constant, without consuming a lot of time, and improving efficiency.

[0066] When a corrugated cardboard is detected to be unqualified, one of the risers 3 moves away from the other riser 3, and the push plate 313 in the other riser 3 moves linearly under the action of the second electric telescopic rod 315, so that the push plate 313 pushes the unqualified corrugated cardboard out of the range of the receiving platform 2. During this period, the multiple blocking plates 404 are in a state of resisting the corrugated cardboard to ensure the corrugated cardboard is stacked.

[0067] Among them, when pushing out unqualified corrugated cardboard, the push plate 313 will drive the extension plate 407 to move synchronously, so that the extension plate 407 can push the blocking plate 404 that is flush with the height of the unqualified corrugated cardboard. Under the action of the guide surface 408, the blocking plate 404 will be out of the state of interference with the unqualified corrugated cardboard, thereby facilitating the pushing out of the unqualified corrugated cardboard.

[0068] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
