Description

Technical Field

[0001] This utility model relates to the field of paper product packaging technology, specifically a packaging device for anti-displacement paper printed materials. Background Technology

[0002] Paper printing packaging equipment is used in the post-printing process to automatically or semi-automatically bundle and wrap printed products such as books, magazines, and brochures. Paper printed products are prone to shifting before packaging, which can affect the packaging quality.

[0003] For example, Chinese Patent Publication No. CN222496918U discloses a paper printing and packaging device, including a packaging machine body. The upper surface of the packaging machine body has two symmetrically arranged connecting grooves, and the bottom wall of each connecting groove has a sliding groove. The packaging machine body is equipped with two sets of limiting components for limiting the paper. Each set of limiting components includes a slider, a connecting block, and a limiting plate. The packaging machine body is equipped with a driving component for driving the two sliders to move closer to each other. The packaging machine body is also equipped with a pressing component. When paper printing needs to be packaged, the worker places the paper printing on the packaging machine body. The driving component drives the two sliders to move closer to each other, thereby causing the connecting block to drive the limiting plate to move closer to each other and press against both sides of the paper printing. Then, the pressing component presses the paper printing, compressing the paper printing downwards. This reduces the probability of the paper printing shifting during the packaging process and improves the packaging efficiency of the paper printing.

[0004] In the operation of existing technology, the spacing of the baffles needs to be adjusted manually, which results in low adjustment efficiency and inflexibility, making it difficult to quickly adapt to different paper sizes. Due to the weight of the paper itself, the paper is prone to unilateral deviation during transmission. Utility Model Content

[0005] The purpose of this invention is to provide a packaging device for anti-deviation paper printed materials, in order to solve the problem in the above-mentioned background technology that the spacing of the baffles needs to be manually adjusted, resulting in low adjustment efficiency and inflexibility, making it difficult to quickly adapt to different paper sizes, and the paper is prone to unilateral deviation during transmission due to its own weight.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging device for anti-deviation paper printed materials, including a conveyor sleeve installed at an angle within a frame, wherein two symmetrically distributed positioning strips are slidably connected inside the conveyor sleeve;

[0007] Both positioning bars are provided with guide bars at their ends, and the two guide bars extend to both sides.

[0008] Preferably, a support plate is fixedly connected to the bottom of the conveying sleeve near the guide bar. Both the guide bar and the support plate are located at the higher end of the conveying sleeve. The support plate is located below the positioning bar, and the positioning bar slides on the top of the support plate.

[0009] Preferably, the overlapping portions of the pallet and the top of the conveying sleeve are provided with equidistantly distributed air blowing grooves, the air blowing grooves and the length direction of the conveying sleeve are perpendicular to each other, and the overlapping areas of the positioning strip and the top of the conveying sleeve are provided with uniformly distributed ventilation holes.

[0010] Preferably, the bottom of the conveying sleeve is fixedly connected to an air distribution plate that completely covers the air blowing groove, and the bottom of the air distribution plate is fixedly connected to an air supply pipe, which is connected to the air supply system.

[0011] Preferably, a sorting component is installed at the lower end of the conveying sleeve. The sorting component includes a fixed frame that is fixedly connected to the air distribution plate and the end of the air supply pipe. Two symmetrically distributed adjusting frames are slidably connected inside the fixed frame.

[0012] Preferably, the two adjustment frames are respectively fixedly connected to the end of the positioning bar away from the guide bar, the sliding direction of the adjustment frame inside the fixed frame is perpendicular to the length direction of the conveying sleeve, and the adjustment frame and the positioning bar move synchronously.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 4This utility model provides the following technical solution: a packaging device for anti-deviation paper printed materials, including a conveyor sleeve 1 installed at an angle within a frame, wherein two symmetrically distributed positioning strips 2 are slidably connected inside the conveyor sleeve 1; Figure 1 As shown, each of the two positioning bars 2 has a guide bar 3 at its end, and the ends of the two guide bars 3 extend to both sides. A drive bar 4 is fixedly connected to the middle of the top of the positioning bar 2. The drive bar 4 extends to the outer side of the top of the conveying sleeve 1 and is slidably connected to the top of the conveying sleeve 1. The sliding direction of the drive bar 4 is perpendicular to the length direction of the conveying sleeve 1. A reverse screw 5 driven by a motor is rotatably connected to the top of the conveying sleeve 1. The reverse screw 5 is threaded into the two drive bars 4. Figure 2 As shown, a support plate 6 is fixedly connected to the bottom of the conveying sleeve 1 near the guide bar 3. Both the guide bar 3 and the support plate 6 are located at the higher end of the conveying sleeve 1. The support plate 6 is located below the positioning bar 2, and the positioning bar 2 slides on the top of the support plate 6. The overlapping part of the support plate 6 and the top of the conveying sleeve 1 is provided with equidistantly distributed air blowing grooves 7. The air blowing grooves 7 and the length direction of the conveying sleeve 1 are perpendicular to each other. The overlapping area of ​​the positioning bar 2 and the top of the conveying sleeve 1 is provided with evenly distributed ventilation holes. A uniform air distribution plate 8 that completely covers the air blowing grooves 7 is fixedly connected to the bottom of the conveying sleeve 1. An air supply pipe 9 is fixedly connected to the bottom of the air distribution plate 8, and the air supply pipe 9 is connected to the air supply system.

[0027] When printed materials of different sizes slide down the inclined conveyor sleeve 1, the motor drives the reverse lead screw 5 to rotate. Since the reverse lead screw 5 is threadedly connected to the two drive bars 4 at the same time, and the threads turn in opposite directions, the rotation of the lead screw will force the two drive bars 4 to slide synchronously towards or away from each other in a direction perpendicular to the length of the conveyor sleeve 1. The drive bars 4 are rigidly connected to the positioning bars 2. Therefore, the positioning bars 2 move horizontally in the slide groove inside the conveyor sleeve 1 with the drive bars 4, thereby quickly adapting to the width of the paper. The guide bar 3 at the end of the positioning bar 2 is designed as an outwardly expanding inclined structure, which can provide guidance when the paper initially contacts, and avoid edge jamming.

[0028] When the printed material slides to the higher end of the conveyor sleeve 1, its bottom contacts the pallet 6. The pallet 6 is fixed to the bottom of the conveyor sleeve 1, supporting the positioning strip 2 and providing a planar track for its sliding. At this time, the air supply system supplies air to the air distribution plate 8 through the air supply pipe 9. After the airflow is evenly distributed by the air distribution plate 8, it is sprayed vertically upward from the air blowing channel 7. The air blowing channel 7 is equidistantly arranged along the length direction perpendicular to the conveyor sleeve 1 to ensure that the airflow covers the entire width of the paper. At the same time, the ventilation holes in the overlapping area of ​​the positioning strip 2 and the top of the conveyor sleeve 1 allow the airflow to pass through, forming a uniform air cushion layer on the bottom surface of the paper, reducing the frictional resistance between the paper and the pallet 6, and making the paper slide smoothly. The upward lifting force of the airflow counteracts the offset torque caused by the weight of the paper, avoiding unilateral tilting.

[0029] During continuous conveying, the positioning strip 2 maintains a fixed spacing according to the preset width, constraining the two sides of the paper. If the paper tends to shift laterally due to inertia or uneven surface, the pressure equalization characteristics of the air cushion will balance the local pressure difference in real time. At the same time, the rigid blocking effect of the positioning strip 2 limits its lateral movement range, thereby ensuring that the paper always moves stably along the central axis of the conveying sleeve 1 to the downstream packaging station.

[0030] Example 2: Based on Example 1, please refer to... Figure 1 - Figure 6 The following structure is also disclosed: a sorting assembly is installed at the lower end of the conveying sleeve 1. The sorting assembly includes a fixed frame 10 fixedly connected to the end of the air distribution plate 8 and the air supply pipe 9. Two symmetrically distributed adjusting frames 11 are slidably connected inside the fixed frame 10; Figures 1-5 As shown, two adjusting frames 11 are respectively fixedly connected to the end of the positioning strip 2 away from the guide strip 3. The sliding direction of the adjusting frame 11 inside the fixed frame 10 is perpendicular to the length direction of the conveying sleeve 1. The adjusting frame 11 and the positioning strip 2 move synchronously as shown. Figure 6 As shown, two adjusting frames 11 are installed with equidistant adjusting bars 12 between the inner sides of the ends away from the positioning bar 2. Each adjusting bar 12 is connected to the others by an X-shaped telescopic rod. The side of the adjusting bar 12 away from the inside of the two adjusting frames 11 is provided with an adjusting groove 13. The X-shaped telescopic rod includes a slider 15 that is slidably connected to the inside of the adjusting groove 13. The two sliders 15 are symmetrically distributed. The outer sides of the two sliders 15 are rotatably connected to a connecting rod 14. The two connecting rods 14 are distributed in an X-shape between the two adjusting bars 12. The intersection of the two connecting rods 14 is rotatably connected to a central block 16. The bottom of the adjusting bars 12 at both ends is provided with a connecting block 17. The adjusting bars 12 are slidably connected to the bottom of the inner side of the conveying sleeve 1 through the connecting block 17. The connection between the connecting block 17 and the adjusting frame 11 is damped.

[0031] When the reverse lead screw 5 drives the positioning bar 2 to move horizontally, the adjustment frame 11 fixed to the end of the positioning bar 2 moves along with it. The adjustment frame 11 is embedded in the slide groove of the fixed frame 10 and slides along the direction perpendicular to the length of the conveying sleeve 1. The fixed frame 10 rigidly connects the air distribution plate 8 and the air supply pipe 9 to provide support for the whole assembly. The movement of the adjustment frame 11 is directly transmitted to the adjustment bar 12 connected to it, so that the spacing of all the adjustment bars 12 changes synchronously, realizing the adaptive matching of the sorting width.

[0032] Each adjusting bar 12 has two symmetrically distributed sliders 15 in its adjusting groove 13. The sliders 15 are hinged to connecting rods 14 on the outside. The connecting rods 14 of adjacent adjusting bars 12 intersect to form an X-shaped structure. The intersection point is rotatably connected through a central block 16. When the adjusting frame 11 drives the adjusting bars 12 at both ends to move horizontally, the X-shaped telescopic rods will expand and contract: if the adjusting frame 11 moves towards each other, the included angle of the connecting rods 14 decreases, pushing the middle adjusting bar 12 to retract inward synchronously; otherwise, it expands outward, ensuring that all adjusting bars 12 are equidistantly distributed.

[0033] The connecting block 17 at the bottom of the adjusting strip 12 slides along the guide rail at the bottom of the inner side of the conveying sleeve 1. The joint between the connecting block 17 and the adjusting frame 11 has damping. When the end face of the paper stack touches the adjusting strip 12, after the paper stack has completely entered the sorting area, the equidistant adjusting strips 12 form a vertical baffle. Combined with the frictionless conveying of the air flotation system, the loose paper is forced to automatically align along the plane of the adjusting strip 12, forming a paper stack with a flat end face that enters the packaging process.
