Description

Technical Field

[0001] The present invention relates to the field of paper packaging box production, and particularly relates to a cardboard conveying deviation rectifying device. Background Art

[0002] Paper packaging boxes play a crucial role in modern logistics transportation. Their production process is both strict and efficient, ensuring the safe transportation of products and meeting the requirements of environmentally friendly packaging. During the production of paper packaging boxes, the cardboard is first formed and cut, and then transformed into finished packaging boxes through the process of pressing and folding.

[0003] In current actual production, the neatly stacked cardboard is usually placed on the loading platform. According to the design specifications, the cardboard is fed into the die-cutting machine for cutting to form specific shapes and sizes. This link requires precise control of the size and shape to ensure the smooth progress of subsequent assembly work.

[0004] However, before die-cutting, due to the long stacking time or unstable stacking of the cardboard, the cardboard is prone to deformation. The deformed cardboard will not only cause positioning deviation during die-cutting, reducing production efficiency, but also affect the squareness after forming the box, thereby weakening the overall compressive strength of the cardboard box. In addition, during the transmission of the cardboard, the deviation of the position will also lead to inaccurate die-cutting positioning, thereby affecting the quality of the finished packaging box.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] To ensure the quality of the packaging box, measures must be taken before die-cutting the cardboard. If the cardboard is stacked for a long time or the stacking is unstable, deformation may occur. The deformed cardboard will not only cause inaccurate positioning during die-cutting, reducing production efficiency, but also damage the squareness after forming the box, thereby weakening the overall compressive strength of the cardboard box. In addition, during the cardboard transmission process, position deviation may also lead to die-cutting positioning errors, affecting the quality of the finished packaging box. Therefore, this embodiment provides a cardboard conveying deviation correction device to solve the problem of cardboard deformation and adjust the position of the cardboard through a deviation correction mechanism to improve the forming quality of the packaging box.

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 11 shown, in some embodiments, a cardboard conveying deviation correction device includes a loading mechanism and a deviation correction mechanism. The loading mechanism is arranged at the frontmost part of the whole device, and the deviation correction mechanism is installed behind the loading mechanism. The specific cardboard transmission process is to transfer the stacked cardboard one by one to the deviation correction mechanism at the loading mechanism, and the deviation correction mechanism adjusts the transmission position to prevent its position from shifting.

[0024] Specifically, the loading mechanism includes a loading platform 8, and a loading stop bar 6 is installed on the upper part of the loading platform 8. The distance between them is set to be greater than the thickness of one cardboard and less than the thickness of two cardboards to ensure that the cardboard can be transported one by one and prevent overlapping transportation of the cardboard. The inside of the loading platform 8 is equipped with a loading component 7, which consists of a plurality of conveying rollers 71. These conveying rollers 71 are arranged in an array along the loading platform 8. Each conveying roller 71 is equipped with a plurality of conveying wheels 712, and the surface of the conveying wheels 712 is covered with an anti-slip pad. The main function of the anti-slip pad is to increase the friction between the conveying wheels 712 and the cardboard, so that the cardboard moves forward under the action of the conveying wheels 712 and passes through the transmission smoothly.

[0025] In addition, the loading mechanism is also provided with a leveling component 5, which includes two leveling rollers 55. These leveling rollers 55 are symmetrically distributed above and below the rear side of the loading stop bar 6. The function of the leveling rollers 55 is to flatten the cardboard to ensure that it is flat and without deformation before entering the deviation correction mechanism.

[0026] The rectifying mechanism includes a conveying platform 2, and a support component 3 and a rectifying component 4 are provided on the upper part of the platform. The rectifying component 4 is closely connected to the support component 3, and the support component 3 is used to provide a supporting effect for the rectifying component 4 to jointly ensure the correct alignment of the cardboard during the conveying process. A transmission component 1 is also provided inside the conveying platform 2, and the transmission component 1 is mainly used to convey the cardboard.

[0027] The rectifying component 4 includes an arc-shaped guide plate 41 and a plurality of movable blocks 43. The arc-shaped guide plate 41 is designed to be located on the front side of the movable blocks 43 to guide the cardboard to smoothly move to the position of the movable blocks 43 during the movement process. The plurality of movable blocks 43 are arranged in an array, and each movable block 43 can be independently adjusted to independently adjust the position of the cardboard to ensure the accurate alignment of the cardboard during the conveying process. In this way, the rectifying mechanism can effectively correct any deviation of the cardboard during the conveying process and ensure the accuracy of the position where the final output cardboard enters the next process.

[0028] The specific working process is as follows: the palletized cardboard is placed on the loading platform 8, the conveying roller 71 rotates to convey the lowermost cardboard forward. When it is conveyed to the flattening component 5, the cardboard passes through the middle of the two flattening rollers 55, and is flattened by heating and pressing by the flattening rollers 55.

[0029] The cardboard processed by the flattening component 5 drops onto the conveying platform 2 in the rectifying mechanism and is driven by the transmission component 1 to move forward along the conveying platform 2. During the movement process, it is guided by the arc-shaped guide plate 41 and guided into the rectifying component 4. The position of the cardboard is detected by an external optical detection device installed on the support component 3. If its position is deviated, the left and right sides of the cardboard are finely adjusted by the movable blocks 43 to be adjusted to the correct position to ensure the accurate position of the cardboard when entering the subsequent processing device and ensure the processing quality.

[0030] It should be noted that the configuration of the loading stop bar 6 ensures that the cardboard can pass through the conveyor belt in sequence, effectively avoiding the overlapping conveyance of the cardboard. At the same time, by heating and pressing the cardboard by the flattening rollers 55, it can be flattened, effectively adjusting the deformation of the cardboard, improving the precision of cardboard die-cutting, and thus improving the quality of the box.

[0031] In the rectifying component 4, the arc-shaped guide plate 41 and the movable blocks 43 precisely adjust the lateral position of the cardboard to ensure the accurate alignment of the cardboard during the conveying process. This effectively corrects the position deviation of the cardboard during the conveying process and ensures the accuracy of its position when entering the die-cutting machine.

[0032] Such as Figure 3 and Figure 4As shown, in some embodiments, the loading platform 8 includes a load-bearing plate 81, which is mainly used to carry the stacked paperboards. First, support side plates 83 are respectively installed on both sides of the load-bearing plate 81, and the two form a stable support mechanism. In order to enhance the stability of the load-bearing plate 81, a support vertical plate 84 is specially designed at its lower part. The function of the support vertical plate 84 is to provide additional support for the load-bearing plate 81 to ensure that it will not deform or bend when bearing the weight of the paperboard. This structural design not only improves the stability of the load-bearing plate 81, but also ensures the flatness of the paperboard during transportation.

[0033] Secondly, a plurality of second grooves 82 are designed on the surface of the carrier plate 81, and these grooves are arranged in an array to ensure accurate correspondence with the conveying roller 71. Such a design enables the paperboard to be more stable and accurate during the conveying process.

[0034] In addition, a plurality of second through holes 85, a third through hole 86 and a fourth through hole 87 are also designed on the supporting side plate 83. Among them, the plurality of second through holes 85 are respectively connected to the plurality of conveying rollers 71 in a one-to-one correspondence, ensuring that the conveying rollers 71 are axially connected to the supporting side plate 83, so that the conveying rollers 71 can rotate smoothly and ensure the conveying of the cardboard. The third through hole 86 and the fourth through hole 87 are respectively arranged at the lower part of the second through hole 85, the third through hole 86 is used to connect with the guide roller 72, and the fourth through hole 87 is used to connect with the fourth motor 73. Such a design not only helps to ensure the smooth rotation of the conveying roller 71.

[0035] Finally, a third slide groove 88 is also designed on the supporting side plate 83 , and the third slide groove 88 is used to connect with the conveying roller 71 located at the upper part.

[0036] In summary, by providing the carrying plate 81 and the supporting side plates 83 on both sides thereof, and by designing a plurality of through holes and conveying rollers 71 on the supporting side plates 83, stable support is achieved during the conveying process of the cardboard.

[0037] like Figure 3 , Figure 4 , Figure 6 and Figure 10 As shown, in some embodiments, the feeding assembly 7 further includes a guide roller 72 and a fourth motor 73. The fourth motor 73 and the guide roller 72 are arranged on the same side, and the fourth motor 73 is transmission-connected with the guide roller 72 and the conveying roller 71, thereby ensuring a smooth and stable conveying process. The fourth motor 73 is fixedly connected to the supporting side plate 83, thereby ensuring the stability and reliability of the motor.

[0038] The conveying roller 71 further includes a conveying rod 711, a plurality of conveying wheels 712 are arranged on the conveying rod 711, one end of the conveying rod 711 is provided with a first gear 713, the first gear 713 is arranged on the same side of the guiding roller 72, and the conveying rod 711 is respectively axially connected to the second through holes 85 on the two supporting side plates 83, thereby ensuring the stable operation of the conveying roller 71.

[0039] The guiding roller 72 includes a second gear 721, a connecting rod 722 and a connecting base 723. The connecting base 723 is fixedly welded to one end of the connecting rod 722, and the connecting base 723 is fixedly connected to the supporting side plate 83 by bolts, ensuring the stability of the guiding roller 72. The second gear 721 is axially connected to the other end of the connecting rod 722, so that the second gear 721 can rotate. The connecting rod 722 passes through the third through hole 86, so that the connecting base 723 and the second gear 721 are respectively located on both sides of the supporting side plate 83, enabling the guiding roller 72 to rotate smoothly.

[0040] The output end of the fourth motor 73 is connected to the fourth through hole 87. Through this connection method, the motor can effectively drive the guiding roller 72 and the conveying roller 71 through the transmission belt, ensuring the smoothness and efficiency of the entire cardboard feeding and conveying process. The purpose of setting the guiding roller 72 is to enhance the tension of the transmission belt, thereby ensuring the effective rotation of the conveying roller 71.

[0041] As Figure 3 、 Figure 4 and Figure 5 shown, in some embodiments, the flattening assembly 5 further includes a third motor 51, a third slider 52, a second lead screw 53 and an adjusting wheel 54. Among them, the third slider 52 is slidably connected to the third sliding groove 88, so that the third slider 52 can move freely in the third sliding groove 88. In addition, the third slider 52 is connected to the upper flattening roller 55 through a bearing, ensuring the stable rotation of the flattening roller 55.

[0042] In order to precisely adjust the height of the third slider 52, the two ends of the second lead screw 53 are fixedly connected to the third slider 52 and the adjusting wheel 54 by welding. The second lead screw 53 is also threadedly connected to the supporting side plate 83, so that the extended height of the second lead screw 53 can be adjusted by rotating the adjusting wheel 54, thereby adjusting the height of the third slider 52 to adapt to cardboard of different thicknesses.

[0043] The third slider 52 is axially connected to one of the flattening rollers 55. The two ends of the second lead screw 53 are respectively fixedly connected to the third slider 52 and the adjusting wheel 54. The second lead screw 53 is threadedly connected to the supporting side plate 83. The adjusting wheel 54 is used to adjust the height of the third slider 52; Both ends of another flattening roller 55 are respectively connected to the supporting side plates 83 through bearings, ensuring the stable rotation of the flattening roller 55. One end of the two flattening rollers 55 is connected to the third motor 51, enabling the third motor 51 to drive the flattening roller 55 to rotate. Thus, the flattening process of the cardboard is achieved. Through this structural design, the flatness of the cardboard can be adjusted more precisely, improving the conveying efficiency and the quality of the cardboard.

[0044] Furthermore, in some embodiments, the flattening roller 55 is provided with a housing 551, a heating chamber 552, and a heater 553. Among them, the heater 553 is disposed inside the housing 551, and a heating chamber 552 is provided between the heater 553 and the housing 551. To improve the heating efficiency, the heating chamber 552 is filled with heat-conducting oil.

[0045] In addition, to ensure that heat can be effectively transferred, the housing 551 is made of a material with good heat transfer performance.

[0046] Even further, in some embodiments, the loading stop bar 6 includes a stop bar bracket 61 and an inclined stop bar 62. Specifically, the stop bar bracket 61 and the inclined stop bar 62 are fixedly connected by screws to better fix and support the inclined stop bar 62.

[0047] The inclined stop bar 62 is provided with an inclination angle, which is to ensure that the cardboard can pass through more smoothly during the conveying process and avoid unnecessary friction or jamming of the cardboard when passing through the flattening assembly 5. The inclination angle is set in the direction away from the flattening assembly 5, which can effectively guide the cardboard to complete the loading and conveying along the correct path.

[0048] A limiting plate 9 is provided on the front side of the loading stop bar 6.

[0049] In addition, to further ensure the stability and accuracy of the cardboard during the loading and conveying process, a limiting plate 9 is specially designed on the front side of the loading stop bar 6. The function of the limiting plate 9 is to limit the lateral movement of the cardboard during the loading and conveying process, ensuring that the cardboard can smoothly pass through and enter the flattening assembly 5 along the predetermined path. Through this design, the cardboard can be effectively prevented from shifting or skewing during the loading and conveying process, thereby improving the stability and reliability of the entire loading and conveying system.

[0050] As Figure 11 and Figure 12 shown, in some embodiments, the deviation rectifying assembly 4 further includes a connecting plate 45, a positioning plate 44, and a plurality of connecting sleeves 47. Specifically, an arc-shaped plate is provided at the front end of the connecting plate 45, and the arc-shaped plate is correspondingly arranged with the arc-shaped guiding plate 41. To ensure the stable connection between the two, the arc-shaped plate and the arc-shaped guiding plate 41 are connected by a fixing rod 42.

[0051] In addition, a telescopic rod 46 is respectively arranged between the movable block 43 and the connecting plate 45. The position of the movable block 43 is adjusted through the telescopic rod 46, and the lateral position of the cardboard is adjusted through the movable block 43.

[0052] To further ensure the accuracy of the cardboard position, a positioning plate 44 is arranged at the rear side of the movable block 43. Similarly, a telescopic rod 46 is also arranged between the positioning plate 44 and the connecting plate 45, and the telescopic rod 46 drives the positioning plate 44 to move.

[0053] Finally, a plurality of connecting sleeves 47 are welded and fixed on the other side of the connecting plate 45. These connecting sleeves 47 are respectively connected with the support assembly 3. Through this structural design, the entire cardboard conveying and rectifying assembly 4 can perform rectifying operations more efficiently and accurately, thereby improving the stability and accuracy of cardboard conveying.

[0054] As Figure 7 shown, in some embodiments, the support assembly 3 is fixedly connected to the conveying platform 2 to ensure the stability of the entire support assembly 3. The support assembly 3 includes two fixed frames 31 and a transmission frame 32. The two fixed frames 31 are respectively arranged on the left and right sides of the transmission frame 32 to ensure the stability and balance of the device. Between the fixed frame 31 and the transmission frame 32, a connecting plate 33 is also arranged to enhance the structural strength and stability of the entire device.

[0055] Specifically, each fixed frame 31 includes a fixed support 311, two first sliders 313, and two first fixing plates 314. Among them, the two first sliders 313 are symmetrically arranged along the center line of the cardboard conveying path and move towards each other.
