Description

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons have three layers or five layers, and seven layers are less used. Each layer is divided into inner paper, corrugated paper, core paper, and face paper. The inner and face papers can be tea board paper or kraft paper, and the core paper is corrugated paper. After the carton is manufactured and formed, it is necessary to use detection equipment to detect the strength of the carton.

[0013] The present invention has the following beneficial effects: (1) The present invention provides a carton multi-faceted strength testing device. When in use, the carton is first placed in a placement rack, and then the drive motor is started. The drive motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives two mounting plates 1 to approach each other. The mounting plate 1 drives two synchronous plates to descend. The synchronous plate drives the movable plates to approach each other. The two movable plates drive two mounting plates 2 to approach each other. At this time, the two mounting plates 1 will move synchronously with the two mounting plates 2. The two mounting plates 1 and the two mounting plates 2 simultaneously approach the carton at the same distance and speed. When a plurality of extrusion plates contact and squeeze the carton from four directions at the same time, the reaction force generated by the carton will push the plurality of extrusion plates to move in four opposite directions. The extrusion plates will drive the telescopic rods to descend. The telescopic rods will squeeze a plurality of L-shaped pressure gauges. The L-shaped pressure gauges will record the pressure values. The rated pressure generated by the plurality of extrusion plates approaching each other is used to test the strength of the carton on multiple faces. (2) The present invention provides a multi-faceted strength testing device for a carton. After the upper, lower, left, and right sides of the carton are tested, the driving motor is reversed. The driving motor causes the two mounting plates 1 and the two mounting plates 2 to move away from each other. During this process, the mounting plate 1 close to the air box will drop. The mounting plate 1 drives the adapting plate to drop. The adapting plate drives the two pushing rods to drop. The pushing rods drive the pushing plate to drop. The pushing plate will push the gas under the pushing plate. The gas will enter the L-shaped gas pipe from the strip gas pipe on the right side of the gas box, and then enter the fixed cavity from the L-shaped gas pipe. The gas enters the fixed cavity. The strip plate will be pushed to move to the left. As the push plate descends, the gas on the left side of the strip plate will enter the air box above the push plate from the L-shaped air pipe and strip air pipe on the left. The strip plate will drive several round rods to move in the process of moving to the left. The round rods will drive several right-angled trapezoidal blocks to rotate. The right-angled trapezoidal blocks will drive the L-shaped ring blocks to rotate 90 degrees, so that the cartons in the rack can be rotated 90 degrees, and the original front and back of the cartons can be transferred to the left and right sides to facilitate the strength test of all aspects of the cartons. (3) The present invention provides a multi-faceted strength testing device for a carton. During the process of the L-shaped annular block rotating 90 degrees, the fixed plate on the L-shaped annular block will contact the semi-conical rod. Under the action of the inclined surface of the semi-conical rod, the semi-conical rod rises, and the semi-conical rod drives the circular fixed block to rise. The circular fixed block drives the limit spring to undergo compression deformation. During the rotation of the fixed plate, the semi-conical rod is inserted into the fixed plate under the elastic force of the limit spring, completing the fixation of the L-shaped annular block, so that the carton in the L-shaped annular block is just rotated 90 degrees. When contacting the fixed plate, the limit long plate is moved, and the limit long plate drives the semi-conical rod to rise, leaving the semi-conical rod from the fixed plate, and then the two mounting plates are brought close together. Since half of the inclined surface of the semi-conical rod is a smooth angled inclined surface, and the other side is a vertical plane, when the two mounting plates are close together to test the front and back sides of the carton, the semi-conical rod will remain in the fixed plate and will not slide out of the fixed plate. (4) The present invention provides a multi-faceted strength testing device for a carton. In the process of the installation plates 1 approaching each other, the push plate rises. At this time, the strip plate moves to the right, and the strip plate drives the round rod to move. The round rod causes the L-shaped annular block to rotate to the right. When the limit block contacts the corresponding limit plate, the L-shaped annular block will not rotate. Since the two installation plates 1 are still approaching each other under the action of the two-way threaded rod, the push plate will continue to rise. The strip plate will continue to drive the round rod to move. Since the L-shaped annular block has been limited by the limit block and the limit plate and will not rotate, the round rod will cause the right-angled trapezoidal block to shrink after contacting the right-angled trapezoidal block. The right-angled trapezoidal block drives the adjusting spring to undergo compression deformation. Since the right-angled trapezoidal block shrinks, it will continue to be misaligned with the round rod, which will neither affect the approach of the installation plates 1 nor the position change of the L-shaped annular block. Similarly, when the semi-conical rod enters the fixed plate, the round rod will also be misaligned with the right-angled trapezoidal block, thereby ensuring the normal operation of the device detection work.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a multi-sided strength detection device for cartons, including a C-shaped frame 1. The C-shaped frame 1 includes an adjusting mechanism 100 provided on the C-shaped frame 1. The adjusting mechanism 100 includes a fixed ring 101 fixedly installed on the front surface of the C-shaped frame 1. An L-shaped annular block 102 is rotatably installed on the inner wall of the fixed ring 101. A placing rack 103 is fixedly installed in the L-shaped annular block 102. Further included are: The placing rack 103 is internally provided with a carton 104. A plurality of rectangular blocks 106 are fixedly installed on the outer wall of the L-shaped annular block 102. The plurality of rectangular blocks 106 are distributed at ninety degrees with the L-shaped annular block 102 as the center. Rectangular grooves 107 are respectively formed on the sides of the plurality of rectangular blocks 106 away from each other. Adjusting springs 108 are respectively fixedly installed on the inner walls of the plurality of rectangular grooves 107 close to each other. Right-angled trapezoidal blocks 109 are respectively fixedly installed at the ends of the plurality of adjusting springs 108 away from each other. The plurality of right-angled trapezoidal blocks 109 are respectively slidably connected to the plurality of rectangular grooves 107. The ends of the plurality of right-angled trapezoidal blocks 109 away from each other respectively extend outside the plurality of rectangular grooves 107.

[0020] As Figure 5 shown, a moving mechanism 2 is arranged at the bottom of the U-shaped frame 1. The moving mechanism 2 includes a fixed frame 201 fixedly installed at the bottom of the U-shaped frame 1. A fixed cavity 202 is formed in the fixed frame 201. A strip-shaped plate 203 is slidably installed in the fixed cavity 202. A strip-shaped groove 204 is formed at the top of the fixed frame 201. A plurality of round rods 205 are fixedly installed at the top of the strip-shaped plate 203. The plurality of round rods 205 are respectively engaged with the plurality of right-angled trapezoidal blocks 109.

[0021] After the gas enters the fixed cavity 202, it will push the strip-shaped plate 203 to move leftward due to the descent of the push plate 302.

[0022] As Figure 5 shown, a transmission mechanism 3 is arranged at the bottom of the U-shaped frame 1. The transmission mechanism 3 includes an air box 301 fixedly installed at the bottom of the U-shaped frame 1. A push plate 302 is slidably installed in the air box 301. Two push rods 303 are fixedly installed at the top of the push plate 302. The tops of the two push rods 303 both extend outside the air box 301 and are both slidably connected to the air box 301. Two strip-shaped air pipes 304 are fixedly installed on the front of the air box 301. L-shaped air pipes 305 are respectively fixedly installed at the tops of the two strip-shaped air pipes 304. The ends of the two L-shaped air pipes 305 away from each other are both fixedly connected to the fixed frame 201.

[0023] The push rod 303 drives the push plate 302 to descend. The push plate 302 will push the gas below it. The gas will enter the L-shaped air pipe 305 from the strip-shaped air pipe 304 on the right side of the air box 301, and then enter the fixed cavity 202 from the L-shaped air pipe 305. After the gas enters the fixed cavity 202, it will push the strip-shaped plate 203 to move to the left. Due to the descent of the push plate 302, the gas on the left side of the strip-shaped plate 203 will enter the air box 301 above the push plate 302 from the L-shaped air pipe 305 and the strip-shaped air pipe 304 on the left side. During the process of moving to the left, the strip-shaped plate 203 will drive a number of round rods 205 to move. The round rods 205 will drive a number of right-angled trapezoidal blocks 109 to rotate. The right-angled trapezoidal blocks 109 drive the L-shaped annular block 102 to rotate and rotate the L-shaped annular block 102 by ninety degrees, so that the carton 104 placed in the placement rack 103 rotates by ninety degrees, transferring the original front and back of the carton 104 to the left and right sides, facilitating the all-round strength detection of the carton 104.

[0024] As Figure 3 shown, a driving mechanism 4 is provided at the top of the C-shaped frame 1. The driving mechanism 4 includes a driving motor 401 fixedly installed at the top of the C-shaped frame 1. Two limiting plates 402 are fixedly installed on the front surface of the C-shaped frame 1. A bidirectional threaded rod 403 is rotatably installed on the C-shaped frame 1. The top end of the bidirectional threaded rod 403 extends outside the C-shaped frame 1 and is fixedly connected to the output shaft of the driving motor 401. Two mounting plates 404 are threadedly sleeved on the bidirectional threaded rod 403, and the two mounting plates 404 are respectively adapted to the two limiting plates 402.

[0025] The driving motor 401 will cause the two mounting plates 404 and the two mounting plates 501 to move away from each other. During this process, the mounting plate 404 close to the air box 301 will descend.

[0026] As Figure 1 shown, two synchronizing mechanisms 5 are provided on the C-shaped frame 1. The synchronizing mechanism 5 includes a mounting plate 501 provided on the front surface of the C-shaped frame 1. A strip-shaped limiting groove 502 is opened on the C-shaped frame 1. A T-shaped limiting block 503 is slidably installed in the strip-shaped limiting groove 502. The T-shaped limiting block 503 penetrates the strip-shaped limiting groove 502, and the front surface of the T-shaped limiting block 503 is fixedly connected to the mounting plate 501. A synchronizing plate 504 is provided on the front surface of the C-shaped frame 1. The right end of the synchronizing plate 504 is hingedly installed with a movable plate 505, and the bottom end of the movable plate 505 is hingedly connected to the mounting plate 501.

[0027] The synchronizing plate 504 drives the movable plates 505 to approach each other. The two movable plates 505 drive the two mounting plates 501 to approach each other. At this time, the two mounting plates 404 will move synchronously with the two mounting plates 501, and the two mounting plates 404 and the two mounting plates 501 approach the carton 104 at the same distance and speed at the same time.

[0028] As shown Figure 4 in the figure, detection mechanisms 6 are respectively arranged on two mounting plates 1-404 and two mounting plates 2-501. The detection mechanism 6 includes an L-shaped pressure detector 601 fixedly mounted at the bottom of the mounting plate 1-404. A U-shaped fixing frame 602 is fixedly mounted on the mounting plate 1-404. A telescopic rod 603 is slidably mounted on the U-shaped fixing frame 602. A circular sleeve 604 is fixedly sleeved on the telescopic rod 603. The telescopic rod 603 passes through the U-shaped fixing frame 602. An extrusion plate 605 is fixedly mounted at the end of the telescopic rod 603. A pressure-measuring spring 606 is sleeved on the telescopic rod 603. The bottom end of the pressure-measuring spring 606 is fixedly connected to the extrusion plate 605. The top end of the pressure-measuring spring 606 is fixedly connected to the U-shaped fixing frame 602.

[0029] When several extrusion plates 605 simultaneously contact and extrude the carton 104 from four directions, the reaction force generated by the carton 104 will push several extrusion plates 605 to move in four opposite directions. The extrusion plates 605 will drive the telescopic rods 603 to descend. The telescopic rods 603 will squeeze several L-shaped pressure detectors 601. The L-shaped pressure detectors 601 will record the pressure values. By generating a rated pressure when several extrusion plates 605 approach each other, the strength of multiple sides of the carton is detected.

[0030] As shown in Fig. 7, two adaptation mechanisms 7 are arranged on the bidirectional threaded rod 403. The adaptation mechanism 7 includes an adaptation plate 701 slidably sleeved on the bidirectional threaded rod 403. The top of the adaptation plate 701 is in contact with the mounting plate 1-404. An adaptation spring 702 is sleeved on the bidirectional threaded rod 403. The top end of the adaptation spring 702 is fixedly connected to the adaptation plate 701. The bottom end of the adaptation spring 702 is fixedly connected to the U-shaped frame 1.

[0031] During the process of the mounting plates 1-404 moving away from each other, the mounting plates 1-404 will contact two adaptation plates 701. The two adaptation plates 701 will move away from each other. The two adaptation plates 701 will simultaneously compress two adaptation springs 702. When the two mounting plates 1-404 leave the thread, they will be affected by the compression elastic force of the two adaptation springs 702, making the two mounting plates 1-404 in a semi-disengaged state. At this time, the driving motor 401 does not need to be turned off, and the device can still operate normally, thereby improving the smoothness and convenience of the device operation.

[0032] As Figure 6 and Figure 8As shown, a limiting mechanism 8 is provided on the L-shaped annular block 102, and the limiting mechanism 8 includes a fixing plate 801 and a limiting block 808 fixedly mounted on the outer wall of the L-shaped annular block 102. A rectangular limiting plate 802 is fixedly mounted on the outer wall of the fixing ring 101, and a semi-conical rod 803 is slidably mounted on the rectangular limiting plate 802. The semi-conical rod 803 penetrates the rectangular limiting plate 802, and a circular fixing block 8031 ​​is fixedly sleeved on the semi-conical rod 803. A limiting circular plate 804 is provided on the sliding sleeve 803, and the end of the limiting circular plate 804 is fixedly connected to the mold frame 1. A limiting long plate 805 is fixedly installed on the top of the semi-conical rod 803. A limiting spring 806 is provided on the semi-conical rod 803. The top of the limiting spring 806 is fixedly connected to the limiting circular plate 804, and the bottom end of the limiting spring 806 is fixedly connected to the circular fixed block 8031. The end of the limiting long plate 805 passes through the corresponding strip limiting groove 502.

[0033] During the rotation of the L-shaped annular block 102 by 90 degrees, the fixing plate 801 on the L-shaped annular block 102 will contact the semi-conical rod 803. Under the action of the inclined surface of the semi-conical rod 803, the semi-conical rod 803 rises, and the semi-conical rod 803 drives the circular fixing block 8031 ​​to rise. The circular fixing block 8031 ​​drives the limit spring 806 to undergo compression deformation. During the rotation of the fixing plate 801, the semi-conical rod 803 is inserted into the fixing plate 801 under the elastic force of the limit spring 806, thereby completing the fixing of the L-shaped annular block 102, so that the L-shaped annular block 102 is fixed. The carton 104 in 02 is just rotated ninety degrees, and when it contacts the fixed plate 801, the limit long plate 805 is pushed, and the limit long plate 805 drives the semi-conical rod 803 to rise, and the semi-conical rod 803 leaves the fixed plate 801, and then the two mounting plates 404 are brought closer. Since half of the inclined surface of the semi-conical rod 803 is a smooth angled inclined surface, and the other side is a vertical plane, when the two mounting plates 404 are close to the front and back of the detection carton 104, the semi-conical rod 803 will remain in the fixed plate 801 and will not slide out of the fixed plate 801.

[0034] When in use, first place the carton 104 into the placement rack 103, then start the drive motor 401, the drive motor 401 drives the bidirectional threaded rod 403 to rotate, the bidirectional threaded rod 403 will drive the two mounting plates 1 404 to approach each other, the mounting plate 1 404 drives the two synchronous plates 504 to descend, the synchronous plate 504 drives the movable plates 505 to approach each other, the two movable plates 505 drive the two mounting plates 2 501 to approach each other, at this time the two mounting plates 1 404 will move synchronously with the two mounting plates 2 501, the two mounting plates 1 404 and the two mounting plates 2 501 approaches the carton 104 at the same distance and speed. When a plurality of squeezing plates 605 contact and squeeze the carton 104 from four directions at the same time, the reaction force generated by the carton 104 will push the plurality of squeezing plates 605 to move in four opposite directions. The squeezing plates 605 will drive the telescopic rods 603 to descend. The telescopic rods 603 will squeeze a plurality of L-shaped pressure gauges 601, and the L-shaped pressure gauges 601 will record the pressure values. After the detection of the upper, lower, left and right sides of the carton is completed, the driving motor 401 is reversed, and the driving motor 401 will make the two mounting plates The first mounting plate 404 and the two second mounting plates 501 move away from each other. During this process, the first mounting plate 404 close to the gas box 301 will drop, and the first mounting plate 404 drives the adapting plate 701 to drop. The adapting plate 701 drives the two pushing rods 303 to drop, and the pushing rods 303 drive the pushing plate 302 to drop. The pushing plate 302 will push the gas under the pushing plate 302, and the gas will enter the L-shaped gas pipe 305 from the strip gas pipe 304 on the right side of the gas box 301, and then enter the fixed cavity 202 from the L-shaped gas pipe 305. After the gas enters the fixed cavity 202, it will push the strip gas pipe 304. The strip plate 203 moves to the left. Due to the descent of the push plate 302, the gas on the left side of the strip plate 203 will enter the air box 301 located above the push plate 302 from the L-shaped air pipe 305 and the strip air pipe 304 on the left. The strip plate 203 will drive a number of round rods 205 to move in the process of moving to the left. The round rods 205 will drive a number of right-angled trapezoidal blocks 109 to rotate. The right-angled trapezoidal blocks 109 will drive the L-shaped annular blocks 102 to rotate and make the L-shaped annular blocks 102 rotate ninety degrees, so that the cartons 104 located in the placement rack 103 can rotate ninety degrees. During the rotation of the L-shaped annular block 102 by 90 degrees, the fixing plate 801 on the L-shaped annular block 102 will contact the semi-conical rod 803. Under the action of the inclined surface of the semi-conical rod 803, the semi-conical rod 803 rises, and the semi-conical rod 803 drives the circular fixing block 8031 ​​to rise. The circular fixing block 8031 ​​drives the limit spring 806 to undergo compression deformation. During the rotation of the fixing plate 801, the semi-conical rod 803 is inserted into the fixing plate 801 under the elastic force of the limit spring 806, thereby completing the fixing of the L-shaped annular block 102, so that the L-shaped annular block 102 is fixed. The carton 104 in 02 is just rotated 90 degrees. When it contacts the fixed plate 801, the limit long plate 805 is moved, and the limit long plate 805 drives the semi-conical rod 803 to rise, and the semi-conical rod 803 is separated from the fixed plate 801, and then the two mounting plates 1 404 are brought close to each other. Since half of the inclined surface of the semi-conical rod 803 is a smooth angle inclined surface, and the other side is a vertical plane, when the two mounting plates 1 404 are close to the front and back of the detection carton 104, the semi-conical rod 803 will remain in the fixed plate 801 and will not slide out of the fixed plate 801. As the mounting plates 404 approach each other, the push plate 302 rises, and the strip plate 203 moves right, which drives the round rod 205 to move, and the round rod 205 causes the L-shaped ring block 102 to rotate right. When the limit block 808 contacts the corresponding limit plate 402, the L-shaped ring block 102 will not rotate. As the two mounting plates 404 are still approaching each other under the action of the bidirectional threaded rod 403, the push plate 302 will continue to rise, and the strip plate 203 will continue to drive the round rod 205 to move. As the L-shaped ring block 102 has been The limit block 808 and the limit plate 402 will not rotate, and the round rod 205 will shrink the right-angled trapezoidal block 109 after contacting it, and the right-angled trapezoidal block 109 will drive the adjusting spring 108 to undergo compression deformation. Since the right-angled trapezoidal block 109 shrinks, it will continue to be misaligned with the round rod 205, which will neither affect the mutual approach of the mounting plate 404 nor the position change of the L-shaped annular block 102. Similarly, when the semi-conical rod 803 enters the fixed plate 801, the round rod 205 will also undergo such misalignment with the right-angled trapezoidal block 109.
