Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, specifically to a compressible packing machine for corrugated cardboard packaging. Background Technology

[0002] Corrugated cardboard, with its excellent cushioning properties, high strength, and cost advantages, has become a widely used material in the packaging industry. Packaging made of corrugated cardboard plays a crucial role in protecting goods and facilitating transportation and storage. However, existing packing machines have problems in the process of using corrugated cardboard packaging for packing. They are difficult to adapt to different sizes of packaging and ensure stable compaction. The positioning structure of many traditional packing machines is fixed and cannot be flexibly adjusted according to the size and shape of the corrugated cardboard packaging. This makes it difficult to position specially sized packaging during the packing process, and the packaging is prone to displacement, affecting the compaction effect. Some small corrugated cardboard packaging may tilt or shift during compression because it cannot be accurately fixed, resulting in uneven compaction. This not only affects the appearance of the packaging but also reduces the protection of the contents. Traditional packing machines lack adaptability and cannot provide stable support according to the packaging surface, causing the packaging to shake easily during the compaction process and reducing packing efficiency. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-4This utility model provides a technical solution: a compressible packing machine for corrugated cardboard packaging, including a frame 1, a placement plate 6 fixedly connected to the outer wall of the frame 1, a limit frame 2 fixedly connected to the top outer wall of the frame 1, a hydraulic cylinder 3 fixedly connected to the top outer wall of the limit frame 2, and a pressing block 4 fixedly connected to the output end of the bottom of the hydraulic cylinder 3. It also includes an adjustment device 5, the outer wall of the adjustment device 5 being slidably connected to the outer wall of the frame 1.

[0020] The adjustment device 5 includes a servo motor 51. A rotating block 52 is fixedly connected to the output end of the servo motor 51. A connecting rod 53 is rotatably connected to both ends of the rotating block 52. A sliding block 54 is rotatably connected to the end of the connecting rod 53 away from the rotating block 52. A positioning device 55 is rotatably connected to the inner wall of the sliding block 54. The outer wall of the bottom of the servo motor 51 is fixedly connected to the outer wall of the frame 1. The outer wall of the extrusion block 4 is slidably connected to the inner wall of the frame 1. The connecting rod 53 rotatably connected to both ends of the rotating block 52 converts the circular motion of the rotating block 52 into the linear motion of the sliding block 54 under the drive of the rotating block 52. At this time, the sliding block 54 at the other end of the connecting rod 53 slides on the outer wall of the frame 1. At the same time, the two ends of the rotating block 52 are relatively close or relatively far apart due to the setting of the connecting rod 53. The sliding of the sliding block 54 realizes the adjustment of the position of the positioning device 55, so that the positioning device 55 can be flexibly adjusted according to the size and position of the corrugated cardboard packaging.

[0021] The positioning device 55 includes a turntable 551, a bidirectional screw 552 is fixedly connected to the outer wall of the turntable 551, a slider 553 is symmetrically threaded to the outer wall of the bidirectional screw 552, a connecting shaft 554 is fixedly connected to the outer wall of the bottom of the slider 553, a torsion spring 555 is sleeved on the outer wall of the connecting shaft 554, an L-shaped plate 556 is rotatably connected to the inner wall of the bottom of the connecting shaft 554, and positioning wheels 557 are rotatably connected to both ends of the L-shaped plate 556.

[0022] One end of the torsion spring 555 is fixedly connected to the outer wall of the slider 553, and the other end of the torsion spring 555 is fixedly connected to the outer wall of the L-shaped plate 556. The outer wall of the bidirectional screw 552 is rotatably connected to the inner wall of the sliding block 54, and the inner wall of the sliding block 54 is slidably connected to the outer wall of the slider 553. The outer wall of the bottom of the positioning wheel 557 contacts the outer wall of the top of the placement plate 6. The slider 553, which is symmetrically threaded to the outer wall of the bidirectional screw 552, will move in opposite directions or in the opposite direction along the screw axis due to the rotation of the bidirectional screw 552. The torsion spring 555, which is sleeved on the outer wall of the bottom connecting shaft 554 of the slider 553, is connected to the outer wall of the sliding block 553 at one end. Block 553 is fixed at one end and L-shaped plate 556 at the other, allowing L-shaped plate 556 to rotate flexibly within a certain angle range. Positioning wheels 557 at both ends of L-shaped plate 556 contact the top of placement plate 6. The distance between the two positioning wheels 557 is adjusted by moving slider 553, thereby positioning corrugated cardboard packaging of different sizes. During the positioning process, the sliding blocks 54 at both ends move closer to each other. Due to the elasticity of torsion spring 555, positioning wheel 557 can adapt to the surface shape of the packaging, providing stable support and positioning force, ensuring that the packaging will not shift during the extrusion process.

[0023] In use, the corrugated cardboard packaging compactor is based on the frame 1. The hydraulic cylinder 3, the adjusting device 5, and the positioning device 55 work together to achieve the positioning and compaction of the corrugated cardboard packaging. The frame 1 provides support for the entire equipment. The placement plate 6 is fixed to the frame 1 and is used to place the corrugated cardboard packaging to be packaged. The limiting frame 2 at the top of the frame 1 ensures the installation stability of the hydraulic cylinder 3. After the hydraulic cylinder 3 is started, its bottom output end pushes the extrusion block 4 to slide down along the inner wall of the frame 1. Under the action of the hydraulic cylinder 3, the extrusion block 4 can apply pressure to the corrugated cardboard packaging placed on the placement plate 6, compacting the contents of the packaging, reducing the packaging volume, making the contents more stable during transportation and storage, and also improving space utilization.

[0024] The adjustment device 5 is installed on the outer wall of the frame 1. The servo motor 51 serves as the power source, and its output end drives the rotating block 52 to rotate. The connecting rod 53, which is rotatably connected to both ends of the rotating block 52, converts the circular motion of the rotating block 52 into the linear motion of the sliding block 54 under the drive of the rotating block 52. At this time, the sliding block 54 at the other end of the connecting rod 53 slides on the outer wall of the frame 1. Meanwhile, the two ends of the rotating block 52 are relatively close or relatively far apart due to the setting of the connecting rod 53. The sliding of the sliding block 54 realizes the adjustment of the position of the positioning device 55, so that the positioning device 55 can be flexibly adjusted according to the size and position of the corrugated cardboard packaging, thereby improving the adaptability of the packing machine to different specifications of packaging.

[0025] When the positioning device 55 is activated, the turntable 551 rotates, and the bidirectional screw 552 fixed on its outer wall rotates synchronously under the drive of the sliding block 54. The sliders 553, which are symmetrically threaded on the outer wall of the bidirectional screw 552, will move in opposite directions along the screw axis due to the rotation of the bidirectional screw 552. The torsion spring 555, which is sleeved on the outer wall of the bottom connecting shaft 554 of the slider 553, is fixed at one end to the slider 553 and at the other end to the L-shaped plate 556, so that the L-shaped plate 556 can rotate flexibly within a certain angle range. The positioning wheels 557 at both ends of the L-shaped plate 556 are connected to the top of the placement plate 6. The sliding block 553 moves to adjust the distance between the two positioning wheels 557, thereby positioning corrugated cardboard packaging of different sizes. During the positioning process, the sliding blocks 54 at both ends move closer to each other. Due to the elasticity of the torsion spring 555, the positioning wheel 557 can adapt to the surface shape of the packaging, providing stable support and positioning force to ensure that the packaging will not shift during the compression process. At the same time, the right angle of the L-shaped plate 556 positions the corners of the corrugated paper, further ensuring the uniformity and stability of the compaction effect, and improving the packaging quality and efficiency.
