Description

Technical Field

[0001] This utility model relates to the field of box gluing machines, and specifically to a deviation correction device for a box gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency. However, if the paper feeding is skewed during the operation of existing box gluing machines, it will lead to inaccurate processing in subsequent processes, resulting in defective products and losses.

[0003] Chinese invention patent publication number "CN103991240B" discloses an automatic box gluing machine, which includes a correction device. The correction device includes a bracket, a mounting plate, an elastic element, a swing arm, a roller, a limiting element, and a baffle. The swing arm is hinged to the mounting plate, the roller is hinged to the swing arm, and the limiting element cooperates with the swing arm for limiting. The roller crushes the cardboard on the belt, the belt is inclined, and the baffle is located on the side of the belt. The belt drives the cardboard and the roller to cooperate to make the cardboard move towards the baffle to achieve the correction of the cardboard.

[0004] However, when the aforementioned correction device corrects the cardboard, the swing arm will drive the limiting component to rotate. When the cardboard deviates too much, the excessive rotation of the swing arm and the limiting component can easily affect the next roller. Furthermore, cardboard that cannot be corrected properly will get stuck on the belt, affecting the normal operation of the correction device.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a correction device for a box gluing machine that can achieve stable correction and keep the cardboard stable during correction, so as to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a correction device for a gluing machine, comprising a frame, a first transmission mechanism mounted on the frame, and a correction mechanism linked to the first transmission mechanism. The first transmission mechanism is used to pull the cardboard to move, and the correction mechanism is used to correct the deviation of the cardboard. The correction mechanism is characterized in that: the correction mechanism includes a correction frame, a correction fixing plate, and several correction swing arms hinged to the correction fixing plate. The correction frame is linked to the first transmission mechanism. The correction fixing plate is mounted on the correction frame. One end of the correction swing arm is provided with a correction roller, and the other end is linked with a correction rod. The correction fixing plate is linked with a limit rod. The limit rod is provided with several spaced limit blocks. Any two adjacent limit blocks form a limit groove. One end of the correction rod is linked to the correction swing arm, and the other end is located in the limit groove.

[0008] By adopting the above technical solution: when the cardboard enters the correction device, the first transmission mechanism and the correction mechanism respectively contact the two ends of the cardboard. The first transmission mechanism can drive the cardboard to move, and the correction mechanism corrects and corrects the offset ends of the cardboard when the cardboard moves, so that the two sides of the cardboard are parallel to the direction of movement, thereby ensuring the accuracy of the cardboard when gluing the box. At the same time, the correction swing arm and the correction roller can correct the offset of the cardboard during the conveying process, ensuring that the cardboard moves along the correct path. The limiting groove limits the maximum moving distance of the correction swing arm and the correction rod, preventing multiple correction swing arms and correction rods from interfering due to excessive cardboard offset, avoiding correction jamming and stopping, and improving the stability of the correction mechanism.

[0009] The correction device of the above-mentioned box gluing machine can be further configured as follows: the first transmission mechanism includes a transmission plate, a plurality of transmission drive wheels disposed on the transmission plate, a plurality of transmission driven wheels disposed on the transmission plate, and a first transmission belt disposed on the transmission plate, the transmission belt being linked with the transmission drive wheels and the transmission driven wheels.

[0010] By adopting the above technical solution: the rotation of the drive wheel drives the first transmission belt to rotate, thereby achieving traction and stable conveying of the cardboard. The driven wheel can improve the stability of the first transmission belt when it rotates, so that the first transmission belt can make stable contact with the surface of the cardboard, ensuring that the cardboard remains stable during the conveying process. This improves the transmission efficiency of the first transmission mechanism for the cardboard and ensures that the cardboard will not slip or get stuck during the conveying process, further improving the overall working efficiency of the gluing machine and the cardboard processing quality.

[0011] The correction device of the above-mentioned box gluing machine can be further configured as follows: the correction frame has several adjustment slots, the correction fixing plate has adjustment holes that are linked to the adjustment slots, the correction frame has several sets of adjustment screws, the adjustment screws are threadedly connected to the correction fixing plate, and the correction frame has an adjustment motor for driving the adjustment screws to rotate.

[0012] By adopting the above technical solution: the adjusting motor drives the adjusting screw to rotate, and the correction fixing plate moves along the axial direction of the adjusting screw, thereby adjusting the distance between the correction mechanism and the first transmission mechanism, so as to achieve precise contact with paperboards of different thicknesses and maintain precise control of paperboard correction. In addition, the adjusting groove and adjusting hole are set accordingly. After the correction mechanism is adjusted, the locking bolt in the adjusting groove is inserted into the adjusting hole and the locking hole is tightened, thereby maintaining the stability of the correction device. At the same time, if there is shaking or deviation during the adjustment process, the accuracy and reliability of the correction device are ensured.

[0013] The correction device of the above-mentioned gluing machine can be further configured as follows: the first transmission mechanism is linked to the first paper pressing mechanism, the paper pressing mechanism includes a first paper pressing fixed plate, a plurality of first paper pressing components spaced apart on the first paper pressing fixed plate, a first paper pressing guide component disposed at both ends of the first paper pressing fixed plate, and a first paper pressing transmission belt sleeved on the first paper pressing mechanism.

[0014] By adopting the above technical solution, the first paper pressing assembly and the first paper pressing guide assembly cooperate with each other to apply a stable downward pressure to the first paper pressing transmission belt, so that the first paper pressing transmission belt and the first transmission belt can make stable contact with both ends of the paperboard, ensuring that the paperboard is in close contact with the first transmission mechanism during the conveying process, thereby improving the stability of the paperboard movement. In addition, the first paper pressing mechanism can move synchronously with the first transmission mechanism, ensuring that the paperboard can be smoothly conveyed forward while being subjected to the pressing force, further enhancing the smoothness of the paperboard conveying.

[0015] The aforementioned gluing machine's correction device can be further configured as follows: the first paper pressing assembly includes a first wheel frame, a first wheel rod disposed on the first wheel frame, and a plurality of first paper pressing wheels disposed on the first wheel rod; the first paper pressing guide assembly includes a first guide plate, one end of the first guide plate is hinged to the end of the first paper pressing fixed plate, and the other end is provided with a first guide wheel; the first guide plate is also provided with a first support wheel for supporting the first paper pressing transmission belt.

[0016] By adopting the above technical solution: the first wheel frame can hinge multiple first paper pressing rollers, thereby improving the support of the first paper pressing assembly for the first paper pressing drive belt, thus applying uniform downward pressure to the cardboard and ensuring that the cardboard remains stable during transportation. Simultaneously, one end of the first guide plate in the first paper pressing guide assembly is hinged to the end of the first paper pressing fixed plate, and the other end is equipped with a first guide wheel, which can adjust the tension of the first paper pressing drive belt, ensuring stable contact between the first paper pressing drive belt and the cardboard surface, guaranteeing the smooth operation of the first paper pressing drive belt. At the same time, the first support wheel can support the first paper pressing drive belt and maintain its tension.

[0017] The correction device of the above-mentioned box gluing machine can be further configured as follows: a second transmission mechanism is provided on the frame, the second transmission mechanism includes a main transmission wheel and a driven transmission wheel, both of which are located on the transmission plate, and the main transmission wheel and the driven transmission wheel are linked by a second transmission belt.

[0018] By adopting the above technical solution: when the cardboard moves to the side of the first transmission belt, the second transmission belt can receive the cardboard and convey it forward again. The rotation of the main transmission wheel drives the second transmission belt to rotate, causing the second transmission belt to convey the cardboard. The tension of the second transmission belt can be adjusted from the transmission wheel to ensure that the second transmission belt is always in a taut state, thereby ensuring that the second transmission belt is in contact with the surface of the cardboard and achieving stability and accuracy in cardboard conveying.

[0019] The correction device of the above-mentioned gluing machine can be further configured as follows: the second transmission mechanism is linked to the second paper pressing mechanism, the second paper pressing mechanism includes a second paper pressing fixed plate, a plurality of second paper pressing components spaced apart on the second paper pressing fixed plate, a second paper pressing guide component disposed at both ends of the second paper pressing fixed plate, and a second paper pressing transmission belt sleeved on the second paper pressing mechanism.

[0020] By adopting the above technical solution: the second paper pressing mechanism can maintain stable contact between the paperboard and the second transmission belt when the second transmission mechanism conveys the paperboard. At the same time, the second paper pressing assembly and the second paper pressing guide assembly cooperate with each other to apply stable downward pressure to the second paper pressing transmission belt, so that the second paper pressing transmission belt and the second transmission belt can make stable contact with both ends of the paperboard, ensuring that the paperboard is in close contact with the second transmission mechanism during the conveying process, extending the conveying distance of the paperboard and improving the conveying stability.

[0021] The above-mentioned correction device for the gluing machine can be further configured as follows: the second paper pressing assembly includes a second wheel frame, a second wheel rod on the second wheel frame, and a plurality of second paper pressing wheels on the second wheel rod; the second paper pressing guide assembly includes a second guide plate, one end of the second guide plate is hinged to the end of the second paper pressing fixed plate, and the other end is provided with a second guide wheel; the second guide plate is also provided with a second support wheel for supporting the second paper pressing transmission belt.

[0022] By adopting the above technical solution: the second wheel frame can be hinged to multiple second pressure rollers via the second wheel rod, thereby improving the support of the second pressure roller assembly for the second pressure roller drive belt, thus applying uniform downward pressure to the cardboard and ensuring that the cardboard remains stable during transportation. Simultaneously, one end of the second guide plate in the second pressure roller guide assembly is hinged to the end of the second pressure roller fixed plate, and the other end is equipped with a second guide roller, which can adjust the tension of the second pressure roller drive belt, ensuring stable contact between the first pressure roller drive belt and the cardboard surface, guaranteeing the smooth operation of the second pressure roller drive belt. At the same time, the second support roller can support the second pressure roller drive belt, maintaining its tension and preventing it from loosening.

[0023] The correction device of the above-mentioned gluing machine can be further configured as follows: the frame is provided with a paper pressing adjustment assembly for adjusting the position of the first paper pressing mechanism and the second paper pressing mechanism. The paper pressing adjustment assembly includes an adjustment frame, an adjustment support plate, and an adjustment fixing plate. The first paper pressing fixing plate and the second paper pressing fixing plate are located on the adjustment fixing plate. The adjustment fixing plate is provided with a sliding groove. The adjustment support plate and the adjustment fixing plate are linked by an adjustment rod. One end of the adjustment rod is slidably engaged with the sliding groove, and the other end is linked with the adjustment support plate. The adjustment support plate is provided with a plurality of first adjustment wheels and a plurality of adjustment support wheels. The adjustment fixing plate is provided with a plurality of second adjustment wheels. The first adjustment wheels, the adjustment support wheels, and the second adjustment wheels are linked by an adjustment belt.

[0024] By adopting the above technical solution: the paper pressing adjustment assembly rotates the first adjusting wheel to drive the adjusting belt to rotate, and the adjusting belt drives the second adjusting wheel to rotate, causing the adjusting rod to slide in the sliding groove, thereby moving the adjusting support plate relative to the adjusting fixed plate, thus adjusting the distance between the adjusting fixed plate and the transmission plate. This allows for simultaneous adjustment of the distance between the first paper pressing mechanism and the first transmission mechanism, as well as the distance between the second paper pressing mechanism and the second transmission mechanism. This ensures that the first and second paper pressing mechanisms can be used for various paperboards of different thicknesses, and that the paperboard can be stably conveyed by the first and second transmission mechanisms. At the same time, the adjusting support wheel can adjust the adjusting belt and maintain its stability, improving the stability of the paper pressing adjustment assembly.

[0025] The beneficial effects of this utility model are as follows:

[0026] First, the correction mechanism forms a limiting groove by setting limiting blocks at intervals on the limiting rod. One end of the correction rod is linked to the correction swing arm, and the other end is movably embedded in the limiting groove. The displacement stroke of the correction rod is rigidly constrained by the groove width, thereby limiting the maximum swing amplitude of the correction swing arm and effectively preventing the interference between multiple correction swing arms caused by excessive cardboard offset and correction jamming. At the same time, the correction frame drives the adjusting screw to rotate by adjusting the motor, which drives the correction fixing plate to move along the axis of the adjusting screw, adjusting the distance between the correction roller and the first transmission mechanism in real time to adapt to the precise contact requirements of cardboard of different thicknesses. After the correction mechanism is adjusted, the locking bolt passes through the adjusting groove of the correction frame and the adjusting hole of the correction fixing plate and locks it, eliminating the risk of shaking during the operation of the mechanism and ensuring that the correction process is stable and reliable.

[0027] Secondly, the first and second paper pressing mechanisms apply uniform elastic pressure to the paper pressing transmission belts through the first and second paper pressing wheels, respectively, so that the paperboard is tightly attached to the surfaces of the first and second transmission belts. At the same time, the paper pressing adjustment component drives the adjustment rod to slide in the sliding groove of the adjustment fixing plate through the adjustment belt, linking the first and second adjustment wheels and the adjustment support wheel. This synchronously adjusts the vertical distance between the first paper pressing mechanism and the first transmission mechanism, and between the second paper pressing mechanism and the second transmission mechanism. A single operation can adapt to various paperboard thicknesses, improving adjustment efficiency while ensuring the pressure consistency of the dual paper pressing mechanisms and extending the stable conveying distance of the paperboard.

Detailed Implementation

[0038] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] like Figures 1 to 8 The diagram shows a correction device for a gluing machine, comprising a frame 1, a first transmission mechanism 2 mounted on the frame 1, and a correction mechanism 3 linked to the first transmission mechanism 2. The first transmission mechanism 2 is used to pull the cardboard to move, and the correction mechanism 3 is used to correct the deviation of the cardboard. The correction mechanism 3 is characterized in that: the correction mechanism 3 includes a correction frame 31, a correction fixing plate 32, and a plurality of correction swing arms 33 hinged to the correction fixing plate 32. The correction frame 31 is linked to the first transmission mechanism 2. The correction fixing plate 32 is mounted on the correction frame 31. One end of the correction swing arm 33 is provided with a correction roller 331, and the other end is linked with a correction rod 34. The correction fixing plate 32 is linked with a limit rod 35. The limit rod 35 is provided with a plurality of spaced limit blocks 351. Any two adjacent limit blocks 351 form a limit groove 352. One end of the correction rod 34 is linked to the correction swing arm 33, and the other end is located in the limit groove 352. When the cardboard enters the correction device, the first transmission mechanism 2 and the correction mechanism 3 respectively contact the two ends of the cardboard. The first transmission mechanism 2 can drive the cardboard to move. The correction mechanism 3 corrects and corrects the offset ends of the cardboard when the cardboard moves, so that the two sides of the cardboard are parallel to the direction of movement, thereby ensuring the accuracy of the cardboard when gluing the box. At the same time, the correction swing arm 33 and the correction roller 331 can correct the offset of the cardboard during the conveying process, ensuring that the cardboard moves along the correct path. The limiting groove 352 limits the maximum moving distance of the correction swing arm 33 and the correction rod 34, preventing interference between multiple correction swing arms 33 and correction rods 34 due to excessive cardboard offset, avoiding correction jamming and stopping, and improving the stability of the correction mechanism 3.

[0040] The first transmission mechanism 2 includes a transmission plate 21, several drive pulleys 22 mounted on the transmission plate 21, and several driven pulleys 23 mounted on the transmission plate 21. A first transmission belt 24 is also mounted on the transmission plate 21, and the first transmission belt 24 is linked with the drive pulleys 22 and the driven pulleys 23. The rotation of the drive pulleys 22 drives the first transmission belt 24 to rotate, thereby achieving traction and stable conveying of the cardboard. The driven pulleys 23 improve the stability of the first transmission belt 24 when it rotates, ensuring stable contact between the first transmission belt 24 and the cardboard surface. This ensures the cardboard remains stable during conveying, improves the transmission efficiency of the first transmission mechanism 2, and prevents slippage or jamming of the cardboard during conveying, further enhancing the overall working efficiency of the gluing machine and the quality of cardboard processing.

[0041] The alignment frame 31 has several adjustment slots 311, and the alignment fixing plate 32 has adjustment holes 321 that are linked to the adjustment slots 311. The alignment frame 31 has several sets of adjustment screws 312, which are threadedly connected to the alignment fixing plate 32. The alignment frame 31 has an adjustment motor 313, which drives the adjustment screws 312 to rotate. The adjustment motor 313 drives the adjustment screws 312 to rotate, and the alignment fixing plate 32 moves axially along the adjustment screws 312, thereby adjusting the distance between the alignment mechanism 3 and the first transmission mechanism 2. This achieves precise contact with cardboard of different thicknesses and maintains precise control over the alignment of the cardboard. In addition, the adjustment slots 311 and adjustment holes 321 are correspondingly arranged. After the alignment mechanism 3 is adjusted, the locking bolt in the adjustment slot 311 is inserted into the adjustment hole 321 and the locking hole is tightened, thereby maintaining the stability of the alignment device. At the same time, any shaking or deviation during the adjustment process ensures the accuracy and reliability of the alignment device.

[0042] The first transmission mechanism 2 is linked to the first paper pressing mechanism 4.

The first paper pressing assemblies 42 and the first paper pressing guide assemblies 43 cooperate with each other to apply a stable downward pressure to the first paper pressing transmission belt 44, so that the first paper pressing transmission belt 44 and the first transmission belt 24 can make stable contact with both ends of the cardboard, ensuring that the cardboard is tightly attached to the first transmission mechanism 2 during the conveying process, thereby improving the stability of the cardboard movement. In addition, the first paper pressing mechanism 4 can move synchronously with the first transmission mechanism 2, ensuring that the cardboard can be smoothly conveyed forward while being subjected to the pressing force, further enhancing the smoothness of the cardboard conveying.

[0043] The first paper pressing assembly 42 includes a first wheel frame 421, a first wheel rod 422 mounted on the first wheel frame 421, and a plurality of first paper pressing rollers 423 mounted on the first wheel rods 422.

The first guide plate 431 is also provided with a first support roller 433 for supporting the first paper pressing transmission belt 44. The first wheel frame 421 can be hinged to multiple first paper pressing rollers 423, thereby improving the support of the first paper pressing assembly 42 for the first paper pressing transmission belt 44, thereby applying uniform downward pressure to the paperboard and ensuring that the paperboard remains stable during the conveying process. Meanwhile, the first guide plate 431 in the first paper pressing guide assembly 43 is hinged at one end to the end of the first paper pressing fixed plate 41, and the other end is provided with a first guide wheel 432, which can adjust the tension of the first paper pressing transmission belt 44 so that the first paper pressing transmission belt 44 can make stable contact with the surface of the paperboard and ensure the smooth operation of the first paper pressing transmission belt 44.

Both the main transmission wheel 51 and the driven transmission wheel 52 are mounted on the transmission plate 21, and the main transmission wheel 51 and the driven transmission wheel 52 are linked to a second transmission belt 53. When the cardboard moves to the side of the first transmission belt 24, the second transmission belt 53 can receive the cardboard and convey it forward again. The rotation of the main transmission wheel 51 drives the second transmission belt 53 to rotate, causing the second transmission belt 53 to convey the cardboard. The driven transmission wheel 52 can adjust the tension of the second transmission belt 53 to keep the second transmission belt 53 in a taut state, thereby ensuring that the second transmission belt 53 is in contact with the surface of the cardboard and achieving stability and accuracy in the cardboard conveying.

[0045] The second transmission mechanism 5 is linked to the second paper pressing mechanism 6. The second paper pressing mechanism 6 includes a second paper pressing fixed plate 61, a plurality of second paper pressing assemblies 62 spaced apart on the second paper pressing fixed plate 61, second paper pressing guide assemblies 63 disposed at both ends of the second paper pressing fixed plate 61, and a second paper pressing transmission belt 64 sleeved on the second paper pressing mechanism 6. When the second transmission mechanism 5 conveys the paperboard, the second paper pressing mechanism 6 can maintain stable contact between the paperboard and the second transmission belt 53. At the same time, the second paper pressing assemblies 62 and the second paper pressing guide assemblies 63 cooperate with each other to apply stable downward pressure to the second paper pressing transmission belt 64, so that the second paper pressing transmission belt 64 and the second transmission belt 53 can maintain stable contact with both ends of the paperboard, ensuring that the paperboard is in close contact with the second transmission mechanism 5 during the conveying process, extending the conveying distance of the paperboard and improving the conveying stability.

[0046] The second paper pressing assembly 62 includes a second wheel frame 621, a second wheel rod 622 mounted on the second wheel frame 621, and a plurality of second paper pressing wheels 623 mounted on the second wheel rod 622.

The second guide plate 631 is also provided with a second support wheel 633 for supporting the second paper pressing transmission belt 64. The second wheel frame 621 can be hinged to multiple second paper pressing wheels 623 through the second wheel rod 622, thereby improving the support of the second paper pressing assembly 62 for the second paper pressing transmission belt 64, thereby applying uniform downward pressure to the paperboard and ensuring that the paperboard remains stable during the conveying process. Meanwhile, one end of the second guide plate 631 in the second paper pressing guide assembly 63 is hinged to the end of the second paper pressing fixed plate 61, and the other end is provided with a second guide wheel 632, which can adjust the tension of the second paper pressing transmission belt 64 so that the first paper pressing transmission belt 44 can make stable contact with the surface of the paperboard and ensure the smooth operation of the second paper pressing transmission belt 64. At the same time, the second support wheel 633 can support the second paper pressing transmission belt 64, maintain the tension of the second paper pressing transmission belt 64, and prevent the second paper pressing transmission belt 64 from loosening.

[0047] The frame 1 is provided with a paper pressing adjustment assembly 7 for adjusting the positions of the first paper pressing mechanism 4 and the second paper pressing mechanism 6. The paper pressing adjustment assembly 7 includes an adjustment frame 71, an adjustment support plate 72, and an adjustment fixing plate 73. The first paper pressing fixing plate 41 and the second paper pressing fixing plate 61 are disposed on the adjustment fixing plate 73.

The adjustment support plate 72 is provided with a plurality of first adjustment wheels 722 and a plurality of adjustment support wheels 723. The adjustment fixing plate 73 is provided with a plurality of second adjustment wheels 732. The first adjustment wheels 722, the adjustment support wheels 723, and the second adjustment wheels 732 are linked by an adjustment belt. The paper pressing adjustment assembly 7 rotates the first adjusting wheel 722 to drive the adjusting belt to rotate, which in turn drives the second adjusting wheel 732 to rotate. This causes the adjusting rod 721 to slide within the sliding groove 731, thereby moving the adjusting support plate 72 relative to the adjusting fixed plate 73. This adjusts the distance between the adjusting fixed plate 73 and the transmission plate 21, allowing for simultaneous adjustment of the distance between the first paper pressing mechanism 4 and the first transmission mechanism 2, as well as the distance between the second paper pressing mechanism 6 and the second transmission mechanism 5. This ensures that the first paper pressing mechanism 4 and the second paper pressing mechanism 6 can be used for various paperboard thicknesses, and that the paperboard can be stably conveyed by the first transmission mechanism 2 and the second transmission mechanism 5. At the same time, the adjusting support wheel 723 can adjust the adjusting belt and maintain its stability, thus improving the stability of the paper pressing adjustment assembly 7.
