DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-9 The present invention provides a technical solution: a paper tube conveying and clamping mechanism, including a conveying device 1, which belongs to the existing technical equipment and is driven by a motor. It realizes the synchronous rotation of the conveying roller through multiple sets of pulleys and transmission belts to achieve the purpose of conveying objects. This case is used to convey paper tubes to a baling machine. The mounting part 2 of this case is mounted on the conveying device 1, which is used to install a paper tube limiting tool and a clamping tool. The limiting part 3 of this case is mounted on the mounting part 2, which is used for limiting during the conveying of paper tubes of different sizes. The adjusting part 4 of this case is mounted on the limiting part 3, which is used to stably drop the paper tube on the conveying roller. The feeding part 5 of this case is mounted on the adjusting part 4, which is used to buffer the impact of the paper tube falling and receive the paper tube. The correcting part 6 of this case is mounted on the limiting part 3, which is used for correcting the paper tube after stacking.

[0023] In this embodiment, in order to detachably install the limiting tool and the clamping tool on the conveying device 1, the mounting portion 2 of this case includes two legs 21, and the two legs 21 are installed at the bottom of one side of the conveying device 1. The conveying rollers on the conveying device 1 are rotatably connected to the bracket 22, and the bracket 22 supports the conveying rollers and cooperates with the legs 21 to support the conveying device 1. The end of the bracket 22 is fixedly connected to the frame 23, and the motor on the conveying device 1 is installed on the frame 23, and the frame 23 supports the motor. A support arm 24 is fixedly connected between the bracket 22 and the frame 23 and between the two legs 21, and a slide groove 25 is installed on the top of the two arms 24. Positioning arms 26 are fixedly connected to the two legs 21, the bracket 22 and the arm 24.

[0024] In order to improve the limiting effect of paper tubes when conveying and stacking paper tubes of different sizes, the limiting part 3 of this case includes two bidirectional studs 31, both ends of the two bidirectional studs 31 are fixedly sleeved with hand wheels 32, the positive threads of the two bidirectional studs 31 are threadedly sleeved with cross beams 33, there are two cross beams 33, the end of the other cross beam 33 is threadedly sleeved on the reverse threads of the two bidirectional studs 31, the bottoms of the two cross beams 33 are fixedly connected with U-shaped plates 34, the tops of the two cross beams 33 are fixedly connected with limiting columns 35, and each limiting column 35 moves through two adjacent The two cross beams 33 extend upward between the conveying rollers to limit the side of the paper tube. An electric push rod 36 is installed on the side away from each other of the two cross beams 33. The two U-shaped plates 34 are slidably connected to the inner wall of the slide groove 25. The ends of one of the two-way studs 31 are respectively rotatably connected to the positioning arms 26 of the support legs 21 and the bracket 22, and the ends of the other two-way studs 31 are respectively rotatably connected to the positioning arms 26 on the other support legs 21 and the support arms 24. The distance between the two cross beams 33 can be reduced or increased by rotating the two-way studs 31 to match the width of the current stack of paper tubes.

[0025] It is worth noting that in order to improve the automatic loading and unloading effect of paper tubes, the adjusting part 4 in this case includes a slide plate 41, which is slidably connected to the inner wall of one of the U-shaped plates 34 and fits with the top edge of the slide groove 25. The slide plate 41 is limited and slides by the U-shaped plate 34 to improve the stability during adjustment. A support plate 42 is fixedly connected to one side of the top of the slide plate 41. The support plate 42 is fixedly connected to the inner rod of the electric push rod 36 on the same side. The electric push rod 36 can adjust the position of the support plate 42 by telescoping. A cross arm 43 is fixedly connected to the top of the support plate 42. There are two adjusting parts 4. The other adjusting part 4 is installed on the other U-shaped plate 34. The two adjusting parts 4 are symmetrically arranged with each other, and the two cross beams 33 are symmetrically arranged with each other.

[0026] In order to improve the safety and stability of paper tube feeding, the feeding part 5 in this case includes a shock-absorbing plate 51, which is used to receive the fallen paper tube and reduce the impact elastic force. On the one hand, it can avoid the large bounce amplitude of the paper tube after it falls and cause deviation. On the other hand, it can also reduce the problem of repeated impact of the paper tube on the conveying roller during continuous operation, thereby causing conveying roller wear and paper tube wear. One side of the shock-absorbing plate 51 is fixedly connected to the cross arm 43, and the top of the shock-absorbing plate 51 is fixedly connected to a tooth arm 52, and the end of the tooth arm 52 is fixedly connected to a limiting arm 53. There are five feeding parts 5, three of which are installed on the cross arm 43 on one side, and the other two feeding parts 5 are installed on the other cross arm 43. The five feeding parts 5 are staggered. The shock-absorbing plate 51 in each feeding part 5 moves through two of the limit columns 35 respectively. The staggered arrangement avoids the collision of parts when the adjustment part 4 adjusts the feeding part 5.

[0027] It is worth noting that in order to perform limit correction according to different stacking heights, the number of the correcting parts 6 in this case is five, and the correcting part 6 includes two clamping sleeves 61, and the two clamping sleeves 61 are respectively clamped on two adjacent limit columns 35. The outer walls of the two clamping sleeves 61 are fixedly connected with connecting arms 62, and the two connecting arms 62 are fixedly connected with a limit arm 63. A rotating rod 64 is rotatably connected between the two connecting arms 62. The middle part of the rotating rod 64 is fixedly sleeved with a gear 65, and the gear 65 fits on the limit arm 63. The inner wall of the limit arm 63 is also slidably connected with a sliding arm 66, and the bottom of the sliding arm 66 is provided with teeth and meshes with the gear 65. A rotating shaft 67 is rotatably connected between the two clamping sleeves 61, and a clamping plate 68 is fixedly sleeved on the outer wall of the rotating shaft 67. The clamping plate 68 can press the stacked paper tubes to ensure the stability of the paper tubes during transportation. Each correction part 6 is respectively aligned with each feeding part 5, and each clamping plate 68 is in contact with the limiting arm 53 adjacent to itself, and each tooth arm 52 is meshed with the gear 65 adjacent to itself.

[0028] Working principle: Use KS-DJ vacuum suction lifter to grab batches of paper tubes. Its principle is to use the vacuum principle to generate adsorption force to grab objects. In the paper tube stacking application, after the suction cup of the vacuum suction lifter contacts the surface of the paper tube, the air is sucked out to form a vacuum environment, so that the suction cup firmly adsorbs the paper tube. For example, use the vacuum suction lifter to grab five paper tubes and move the five paper tubes to the top of the conveying device 1. According to the actual size of the paper tube, rotate the hand wheel 32 to drive the two-way stud 31, so that the two beams 33 are close to each other, so that the distance between the limit columns 35 on both sides reaches a width sufficient to accommodate three paper tubes arranged horizontally. At the same time, the adjustment part 4 moves with the beam 33, and the correction part 6 moves with the limit column 35, which will not cause misalignment between components. Then, the three paper tubes are released and fall vertically onto the five shock-absorbing plates 51 for loading, thereby reducing the bounce amplitude of the paper tubes and protecting the paper tubes and the conveying rollers. Then, the vacuum suction lifter is moved to release the remaining two paper tubes onto the three paper tubes for palletizing. At this time, the limiting columns 35 on both sides limit the three paper tubes located below, which will not cause the problem of paper tube deflection during transportation. After the palletizing is completed, the electric push rods 36 are used to extend synchronously to push the support plates 42 on both sides away from each other, and the slide plate 41 slides along the inner wall of the U-shaped plate 34 to improve stability. The cross arm 43 drives the shock-absorbing plate 51 on the same side away from the conveying roller, so that the shock-absorbing plates 51 on both sides are pulled away from the bottom of the paper tube. During the pulling-out period, the limiting columns 35 on both sides provide limiting to prevent the paper tube from rolling to both sides due to friction.

[0029] When the damping plate 51 is pulled out, the paper tube falls onto the conveying roller at a short distance, which greatly reduces the problem of wear caused by the paper tube hitting the conveying roller, and the falling height is only the thickness of the damping plate 51, which will not cause the paper tube to bounce up significantly, thereby improving the safety of paper tube loading. At the same time, during the movement of the damping plate 51, the tooth arm 52 follows the movement and meshes with the corresponding gear 65, so that the gear 65 rotates within the limit limit of the rotating rod 64 and the limit arm 63, and at the same time, the meshing teeth of the sliding arm 66 drive the sliding arm 66 to move toward the clamping plate 68, and the sliding arm 66 contacts and pushes the clamping plate 68 to rotate, so that the clamping plate 68 forms an inclined angle to adapt to the height of the current stacked paper tubes, and the clamping plate 68 is tilted. The two paper tubes located above are pressed down to correct the position of the paper tubes and prevent them from being skewed, thereby further improving the stability of paper tube loading. During the period when the conveying device 1 transports the paper tubes to the baling machine through the conveying rollers, the five paper tubes are stacked to form a trapezoidal structure, and a trapezoidal space is also formed between the mutually inclined clamps 68 on both sides and the conveying rollers, thereby improving the limiting ability of the paper tubes during transportation, so that the paper tubes can be stably sent out along the trapezoidal space and enter the baling machine, and will not cause the problem of shaking and deflection of the paper tubes during transportation. It is worth explaining that in this case, the clamps 68 press the paper tubes not to clamp the paper tubes tightly, but to use a certain pressure to fit the paper tubes for spatial limitation, which does not affect the sliding of the paper tubes on the conveying rollers.

[0030] After the paper tubes are bundled, they enter the post-process and move away from the conveying device 1. At this time, the electric push rod 36 contracts, causing the shock-absorbing plate 51 to reset. At the same time, the tooth arm 52 drives the gear 65 to rotate and causes the sliding arm 66 to move away from the splint 68. When the limiting arm 53 approaches and contacts the bottom end of the splint 68, the splint 68 is pushed to rotate and reset, thereby automatically restoring the initial state to facilitate the development of continuous operations.
