Abstract

This invention discloses a coding device for post-processing of corrugated cardboard boxes, relating to the technical field of corrugated cardboard box processing equipment. It includes a base, a limiting guide plate, a coding machine, and an adjustment mechanism. The invention utilizes an adjustment mechanism where a handle drives a second rotating disc. Through the cooperation of a bidirectional lead screw, a movable sliding plate, a movable pull rod, a limiting collar, and an adjustment frame, the distance between two coding machines can be adjusted. Simultaneously, through the cooperation of a guide plate, connecting pull rod, movable slider, fixed guide rod, and a second spring, the position of the cardboard box can be guided and limited.

When the coding machine, pushed by the cardboard box by a guide block, adheres to the outer wall of the cardboard box through a bonding mechanism, the nozzle sprays paint onto the outer wall of the cardboard box, thus achieving the purpose of coating cardboard boxes of different heights and widths.

Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box processing equipment technology, specifically a coding device for post-processing of corrugated cardboard boxes. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper that has been processed by corrugating rollers to form a wave shape. Corrugated boxes are made by die-cutting, creasing, stapling or gluing corrugated cardboard. In the production process of existing corrugated boxes, relevant markings need to be sprayed on the outer wall of the box using an inkjet printer according to its purpose, such as production schedule, fragile items, etc.

[0003] In existing inkjet printing equipment, the cartons are manually moved onto the conveyor belt, causing multiple cartons to be out of sync and requiring guidance. However, corrugated cartons vary in height and width depending on their intended use, necessitating manual adjustment of the inkjet printer's position when printing on different batches. While some inkjet printing equipment uses two printers at the same height to simultaneously print on both sides of the carton for improved efficiency, this can lead to inconsistencies in height during adjustment, affecting the accuracy of the printing. To avoid these issues, we propose an inkjet printing device for post-processing of corrugated cartons. Summary of the Invention

[0004] The purpose of this invention is to provide a coding device for post-processing of corrugated cardboard boxes, in order to achieve the purpose of spraying coating on cardboard boxes of different heights and widths.

When the carton contacts the outer wall of the guide plate, it moves under the guidance of the guide plate until the outer wall of the carton contacts the outer wall of the adjustment frame. When the carton contacts the outer wall of the guide block, the inkjet printer, pushed by the guide block, uses the bonding mechanism to ensure a tight fit between the outer wall of the inkjet printer and the outer wall of the carton. This allows the nozzles to spray paint onto the outer wall of the carton according to a specified method, thus enabling the spraying operation of cartons of different heights and widths.

An adjustment mechanism 2 is arranged laterally on the support frame 6. The adjustment mechanism 2 is used to adjust the distance and height between the two coding machines 7.

[0039] The adjustment mechanism 2 includes: a first adjustment component, a second adjustment component, a locking component, and a guide component;

[0040] The first adjustment component, which is horizontally arranged on the support frame 6, is used to adjust the distance between the two inkjet printers 7;

[0041] A second adjustment component, vertically mounted on the support frame 6, is used to adjust the height of the two inkjet printers 7;

[0042] A locking assembly installed on the outer wall of one side of the support frame 6 is used to lock the first adjustment assembly and the second adjustment assembly synchronously.

[0043] A guide assembly located at one end of the top of the base 1 is used to guide the movement of the carton;

[0044] The first adjustment component includes:

[0045] A second rotating disk 2010 is set on one side of the outer wall of the support frame 6. A bidirectional screw 2019 is fixedly connected to one side of the second rotating disk 2010 and is rotatably connected to the support frame 6 via a rotating shaft. A movable sliding plate 2017 that is slidably connected to the support frame 6 is symmetrically sleeved on both sides of the outer wall of the bidirectional screw 2019. The movable sliding plate 2017 is threadedly connected to the bidirectional screw 2019. Two movable pull rods 203 that penetrate to the outside of the support frame 6 are symmetrically formed at both ends of the movable sliding plate 2017. A limiting collar 208 is formed at the end of the movable pull rod 203 away from the movable sliding plate 2017. Two adjusting frames 201 that are slidably connected to the limiting collar 208 are symmetrically arranged on both sides of the support frame 6.

[0046] The guiding components include:

[0047] A guide plate 2013 is sleeved on the outer wall of one end of the adjusting frame 201. A connecting rod 2014 is sleeved on the end of the guide plate 2013 away from the adjusting frame 201. A movable slider 2025 that is laterally slidably connected to the bottom end of the connecting rod 2014 is fixedly connected to the bottom end of the connecting rod 2014. A fixed guide rod 2021 that is fixedly connected to the base 1 is sleeved on the inner wall of the movable slider 2025. A second spring 2024 is sleeved on the outer wall of the fixed guide rod 2021. The two ends of the second spring 2024 are in contact with the outer wall of the movable slider 2025 and the inner wall of the base 1, respectively.

[0048] A bonding mechanism 3 is provided on the side of the two inkjet printers 7 that are far apart from each other. The bonding mechanism 3 is used to make the inkjet printers 7 adhere to the outer wall of the carton for spraying.

[0049] In this embodiment: When using this device, the carton is placed on the upper surface of the conveyor belt 4. At this time, the locking component is released from locking the first adjustment component and the second adjustment component by using a tool. At the same time, according to the width of the carton, the second rotating disk 2010 is rotated by using the handle. At the same time, according to the height of the carton and the spraying position, the height of the two inkjet printers 7 is adjusted by using the handle to adjust the height of the two inkjet printers 7. During this process, the locking component can be used to lock and position the first adjustment component and the second adjustment component respectively.

[0050] When the second rotating disk 2010 is rotated by the handle, the bidirectional lead screw 2019, driven by the second rotating disk 2010, drives the two movable slide plates 2017 to move towards each other along the inner wall of the support frame 6. During this process, the movable pull rod 203, driven by the movable slide plates 2017, drives the limiting collar 208 to move along the inner wall of the support frame 6. At the same time, the adjusting frame 201, driven by the limiting collar 208, drives the inkjet printer 7 to move through the bonding mechanism 3, so as to adjust the distance between the two inkjet printers 7 according to the width of the carton. Meanwhile, the guide plate 2013, driven by the adjusting frame 201, drives the movable slider 2025 to move along the outer wall of the fixed guide rod 2021 through the connecting pull rod 2014. At this time, the movable slider 2025 compresses the second spring 2024 to retract, and the guide plate 2013 rotates on the outer wall of the adjusting frame 201 and the connecting pull rod 2014, thereby guiding and limiting the position of the carton.

[0051] After the position of the inkjet printer 7 is adjusted, the motor is started to drive one transmission roller to rotate. At the same time, one transmission roller drives another transmission roller to rotate through the conveyor belt 4. The carton moves under the drive of the conveyor belt 4. When the carton comes into contact with the outer wall of the guide plate 2013, the position is adjusted under the guidance of the guide plate 2013 until the outer wall of the carton comes into contact with the outer wall of the adjusting frame 201, which can realize the guiding and limiting of the carton.

[0052] When the carton comes into contact with the outer wall of the guide block, the inkjet printer 7, pushed by the guide block, uses the bonding mechanism 3 to make the outer wall of the inkjet printer 7 fit tightly against the outer wall of the carton. When the carton moves to the designated position, the paint is delivered to the inside of the nozzle by the paint pump. At the same time, the nozzle sprays the paint onto the outer wall of the carton according to the specified method, thereby realizing the spraying operation of cartons of different heights and widths.

[0053] In a preferred embodiment of the present invention, the second adjustment component includes:

[0054] A lifting screw 2016 is rotatably connected to the top of the support frame 6 and located between the two limiting guide plates 5 via a rotating shaft. A lifting slide plate 207, which is sleeved on the outer wall of the lifting screw 2016 and fitted onto the outer walls of the two adjusting frames 201, is threaded onto the lifting screw 2016. A second bevel gear 206 is fixedly connected to the top of the lifting screw 2016. The second bevel gear 206 is located on the upper surface of the lifting slide plate 207, and a first bevel gear 205 is meshed with its outer wall. A transmission shaft 204 is fixedly connected to one side of the first bevel gear 205 and rotatably connected to a limiting guide plate 5. A first transmission wheel 202 is fixedly connected to the side of the transmission shaft 204 away from the first bevel gear 205. A synchronous belt 2023 is meshed and sleeved on the outer wall of the first transmission wheel 202. A second transmission wheel 2026 is meshed and sleeved on the bottom end of the inner wall of the synchronous belt 2023. A first rotating disk 209 is fixedly connected to one side of the second transmission wheel 2026. The first rotating disk 209 is located on one side of the outer wall of the support frame 6.

[0055] In this embodiment: when the first rotating disk 209 is rotated by the handle, the second transmission wheel 2026, driven by the first rotating disk 209, drives the first transmission wheel 202 to rotate via the synchronous belt 2023. At the same time, the first bevel gear 205, driven by the first transmission wheel 202 via the transmission shaft 204, meshes with and drives the second bevel gear 206 to rotate. At this time, the lifting screw 2016, driven by the second bevel gear 206, drives the lifting slide plate 207 to rise and fall along the outer wall of the two limiting guide plates 5. Meanwhile, the adjusting frame 201, driven by the lifting slide plate 207, moves along the inner wall of the limiting collar 208, and drives the inkjet printer 7 to rise and fall via the bonding mechanism 3, thereby adjusting the height of the inkjet printer 7 according to the height of the carton and the spraying position.

[0056] In a preferred embodiment of the present invention, the locking component includes:

[0057] A fixing plate 2011 is fixedly connected to the outer wall of one side of the support frame 6. Two movable slide rods 2015 are symmetrically sleeved on the upper and lower ends of the fixing plate 2011. One end of the two movable slide rods 2015 is fixedly connected to two positioning blocks 2027 that are engaged with the first rotating disk 209 and the second rotating disk 2010, respectively. A first spring 2020 is sleeved on the outer wall of the movable slide rod 2015. The two ends of the first spring 2020 are in contact with the positioning blocks 2027 and the outer wall of the fixing plate 2011, respectively. A limiting block 2018 is fixedly connected to the end of the movable slide rod 2015 away from the positioning blocks 2027. The limiting block 2018 is in contact with the outer wall of the fixing plate 2011 and the support frame 6. A locking plate 2012 is provided on the outer wall of the end of the limiting block 2018 away from the movable slide rod 2015. A bolt 2022 that is threadedly connected to the fixing plate 2011 is slidably connected to the locking plate 2012.

[0058] In this embodiment: when the handles are used to rotate the first rotating disk 209 and the second rotating disk 2010 respectively, during this process, the two positioning blocks 2027, under the pressure of the first rotating disk 209 and the second rotating disk 2010 respectively, push the moving slide bar 2015 to move along the inner wall of the fixed plate 2011 and compress the first spring 2020 to retract. At the same time, under the push of the moving slide bar 2015, the limiting pressure block 2018 pushes the locking pressure plate 2012 along the outer wall of the support frame 6 to move along the outer wall of the bolt 2022. When the positioning slots on the outer walls of the first rotating disk 209 and the second rotating disk 2010 move to the end of the positioning block 2027, the first spring 2020 pushes the positioning block 2027 to reset by rebounding, so that the two positioning blocks 2027 can engage and fix the first rotating disk 209 and the second rotating disk 2010 respectively. Then, the rotating bolt 2022 squeezes the locking plate 2012 to squeeze the squeezing surfaces of the two limiting blocks 2018, thereby realizing the synchronous locking of the first rotating disk 209 and the second rotating disk 2010.

[0059] In a preferred embodiment of the present invention, the bonding mechanism 3 includes:

[0060] Two sets of movable push shafts 304 are symmetrically arranged on the opposite side of the two inkjet printers 7 and fixedly connected to the guide block. One set of movable push shafts 304 has a limiting sleeve plate 302 sleeved on one side of its outer wall. One end of the limiting sleeve plate 302 is formed with a positioning sleeve plate that is sleeved on the outer wall of the adjusting frame 201. The set of movable push shafts 304 has two upper and lower ends symmetrically arranged on one side of the inkjet printers 7. The outer wall of the movable push shaft 304 is sleeved with a third spring 301. The two ends of the third spring 301 are in contact with the limiting sleeve plate 302 and the outer wall of the guide block, respectively. The two ends of the inkjet printers 7 are symmetrically formed with a fourth spring 305. The outer wall of the fourth spring 305 is sleeved with a limiting sleeve block 303 integrally formed with the adjusting frame 201. The limiting sleeve plate 302 has a movable groove for the movable push shaft 304 to slide longitudinally. The limiting sleeve block 303 has a limiting groove for the fourth spring 305 to slide longitudinally.

[0061] In this embodiment: After the position of the inkjet printer 7 is adjusted, the starting motor drives one transmission roller to rotate. Simultaneously, one transmission roller drives another transmission roller to rotate via the conveyor belt 4. The carton moves under the drive of the conveyor belt 4. When the carton contacts the outer wall of the guide plate 2013, its position is adjusted under the guidance of the guide plate 2013 until the outer wall of the carton contacts the outer wall of the adjusting frame 201, thus achieving guiding and limiting of the carton. When the carton contacts the outer wall of the guide block, the inkjet printer 7 is pushed by the guide block... Under the influence of the fourth spring 305, the machine moves along the inner wall of the limiting sleeve 303 and pushes the moving push shaft 304 along the inner wall of the limiting sleeve 302. During this process, the inkjet printer 7 compresses the third spring 301 to retract, so that the outer wall of the inkjet printer 7 can be precisely fitted with the outer wall of the carton. When the carton moves to the designated position, the paint is delivered to the inside of the nozzle by the paint pump. At the same time, the nozzle sprays the paint onto the outer wall of the carton according to the specified method, thereby realizing the spraying operation of cartons of different heights and widths.

[0062] In a preferred embodiment of the present invention, the outer walls of the upper and lower ends of the positioning block 2027 are both inclined, and the outer walls of the first rotating disk 209 and the second rotating disk 2010 are circumferentially provided with a plurality of positioning slots that match the outer walls of the positioning block 2027. The first rotating disk 209 and the second rotating disk 2010 are each provided with a handle on the side away from the support frame 6. The outer walls of the upper and lower ends of one end of the locking pressure plate 2012 are symmetrically inclined, and the two limiting pressure blocks 2018 are provided with a pressing surface that matches the outer wall of the locking pressure plate 2012 at the position where they meet the fixing guide rod 2021.

[0063] In this embodiment: the inclined outer wall allows the two positioning blocks 2027 to be displaced under the pressure of the first rotating disk 209 and the second rotating disk 2010, which is beneficial for the individual rotation of the first rotating disk 209 and the second rotating disk 2010. At the same time, through the cooperation of the pressing surface and the inclined outer wall, the two limiting blocks 2018 can be locked and fixed synchronously by the two positioning blocks 2027 under the locking pressure of the fixed guide rod 2021.

[0064] The working principle of this invention is as follows: When using this device, the carton is placed on the upper surface of the conveyor belt 4. At this time, the screw 2022 is rotated by the tool to release the pressure on the locking plate 2012. Simultaneously, according to the height, spraying position, and width of the carton, the first rotating disk 209 and the second rotating disk 2010 are rotated by the handle. During this process, the two positioning blocks 2027, under the pressure of the first rotating disk 209 and the second rotating disk 2010, push the moving slide bar 2015 to move along the inner wall of the fixed plate 2011 and compress the first spring 2020 to retract. At the same time, the limiting block 2018 is pushed by the moving slide bar 2015. Next, the locking plate 2012 is pushed along the outer wall of the support frame 6 to move along the outer wall of the bolt 2022. When the upper and lower positioning slots on the outer walls of the first rotating disk 209 and the second rotating disk 2010 move to the end of the positioning block 2027, the first spring 2020 pushes the positioning block 2027 to reset by rebound, so that the two positioning blocks 2027 can engage and fix the first rotating disk 209 and the second rotating disk 2010 respectively. Then, the bolt 2022 is rotated to squeeze the locking plate 2012 to squeeze the squeezing surfaces of the two limiting blocks 2018, thereby realizing the synchronous locking of the first rotating disk 209 and the second rotating disk 2010.

[0065] When the first rotating disk 209 is turned by the handle, the second transmission wheel 2026, driven by the first rotating disk 209, drives the first transmission wheel 202 to rotate via the synchronous belt 2023. At the same time, the first bevel gear 205, driven by the first transmission wheel 202 via the transmission shaft 204, meshes with the second bevel gear 206 to rotate. At this time, the lifting screw 2016, driven by the second bevel gear 206, drives the lifting slide plate 207 to rise and fall along the outer wall of the two limit guide plates 5. Meanwhile, the adjusting frame 201, driven by the lifting slide plate 207, moves along the inner wall of the limit collar 208, through the limit sleeve block 303 and the fourth spring 305, to drive the inkjet printer 7 to rise and fall, thereby adjusting the height of the inkjet printer 7 according to the height of the carton and the spraying position.

[0066] When the second rotating disk 2010 is rotated by the handle, the bidirectional lead screw 2019, driven by the second rotating disk 2010, drives the two movable slide plates 2017 to move towards each other along the inner wall of the support frame 6. During this process, the movable pull rod 203, driven by the movable slide plates 2017, drives the limiting collar 208 to move along the inner wall of the support frame 6. At the same time, the adjusting frame 201, driven by the limiting collar 208, drives the inkjet printer through the limiting sleeve block 303 and the fourth spring 305. 7 is moved to adjust the distance between the two inkjet printers 7 according to the width of the carton. At the same time, the guide plate 2013, driven by the adjusting frame 201, drives the moving slider 2025 to move along the outer wall of the fixed guide rod 2021 through the connecting rod 2014. At this time, the moving slider 2025 compresses the second spring 2024 to retract, and the guide plate 2013 rotates on the outer wall of the adjusting frame 201 and the connecting rod 2014, thereby guiding and limiting the position of the carton.

[0067] It should be noted that: multiple nozzles are installed on the side of the two inkjet printers 7 that are close to each other, and the side of the two inkjet printers 7 that are far from each other are connected to the paint pump through the infusion pipe, and the paint pump is connected to the paint tank through the extraction pipe.

[0068] After the position of the inkjet printer 7 is adjusted, the motor is started to drive one transmission roller to rotate. At the same time, one transmission roller drives another transmission roller to rotate through the conveyor belt 4. The carton moves under the drive of the conveyor belt 4. When the carton comes into contact with the outer wall of the guide plate 2013, the position is adjusted under the guidance of the guide plate 2013 until the outer wall of the carton comes into contact with the outer wall of the adjusting frame 201, which can realize the guiding and limiting of the carton.

[0069] When the carton comes into contact with the outer wall of the guide block, the inkjet printer 7, pushed by the guide block, moves along the inner wall of the limiting sleeve 303 via the fourth spring 305, and pushes the moving push shaft 304 along the inner wall of the limiting sleeve 302. During this process, the inkjet printer 7 compresses the third spring 301 to contract, so that the outer wall of the inkjet printer 7 can fit tightly against the outer wall of the carton. When the carton moves to the designated position, the paint is delivered to the inside of the nozzle by the paint pump, and the nozzle sprays the paint onto the outer wall of the carton according to the specified method, thereby realizing the spraying operation of cartons of different heights and widths.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
