Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically a self-limiting conveying device for cold heat sealing packaging. Background Technology

[0002] In the cold foil stamping packaging industry, the conveying and positioning of packaging materials directly affects the adhesion and edge integrity of the cold foil stamping pattern, which is a key link in ensuring product quality.

[0003] For example, patent number CN223199712U discloses a gift box packaging cold ironing device, including a base and a working frame fixedly installed on the outer top surface of the base. Rotating shafts arranged at equal intervals are rotatably installed on the inner side walls of both sides of the working frame. A conveyor belt is connected to the outer peripheral side walls of several sets of rotating shafts. A block is fixedly installed at the center position of the outer top surface of both sides of the working frame. Positioning components for anti-deviation calibration of the gift boxes transported on the conveyor belt are provided on the inner side walls of the two corresponding blocks.

[0004] While the aforementioned patents have technical advantages in positioning, the rigid limiting structure cannot adapt to the needs of packaging materials with different widths, thicknesses, and hardnesses in multi-variety, small-batch production. If the material specifications change, the machine needs to be stopped for complex component replacement or debugging, which is not only cumbersome and time-consuming, but also significantly reduces production efficiency and increases labor and equipment adaptation costs.

The threaded rod is driven to rotate by rotating the knob. When the threaded rod rotates, it will generate displacement along the axial direction, thereby pushing the adjusting plate to move.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a self-limiting conveying device for cold ironing packaging processing, comprising: a conveyor 1, a cold ironing machine 2 fixedly connected to the outer wall of the top of the conveyor 1, and a limiting structure 3 symmetrically fixedly connected to the outer wall of the top of the conveyor 1; the limiting structure 3 includes a support plate 31, guide holes 32 symmetrically opened on the outer wall of the support plate 31, a threaded rod 33 threadedly connected to the inner wall of the support plate 31, a knob 34 fixedly connected to the outer wall of the threaded rod 33, an adjusting plate 35 rotatably connected to the outer wall of the threaded rod 33 on the side away from the knob 34, a guide rod 36 slidably connected to the inner wall of the guide hole 32, and an anti-detachment plate 37 fixedly connected to the outer wall of the guide rod 36.

[0025] The inner wall of the adjusting plate 35 is slidably connected to the outer wall of the guide rod 36, and the outer wall of the bottom of the support plate 31 is fixedly connected to the outer wall of the top of the conveyor 1. The threaded rod 33 is driven to rotate by rotating the knob 34. When the threaded rod 33 rotates, it will generate displacement along the axial direction, thereby pushing the adjusting plate 35 to move. The support plate 31 is symmetrically arranged on both sides of the conveyor 1.

[0026] An arc-shaped limiting plate 38 is fixedly connected to the outer wall of the guide rod 36 on the side away from the anti-detachment plate 37. A roller 381 is rotatably connected to the inner wall of the arc-shaped limiting plate 38 on the side away from the guide rod 36. An anti-slip sleeve 382 is fixedly connected to the outer wall of the roller 381. A compression spring 39 is symmetrically fixedly connected to the outer wall of the arc-shaped limiting plate 38.

[0027] Rollers 381 are arranged laterally along the outer wall of the arc-shaped limiting plate 38. Compression spring 39 is set outside the guide rod 36, and the outer wall of the side of the compression spring 39 away from the arc-shaped limiting plate 38 is fixedly connected to the outer wall of the adjusting plate 35. When the adjusting plate 35 moves toward the arc-shaped limiting plate 38, the compression spring 39 is squeezed and stored, which can adjust the spring preload on the arc-shaped limiting plate 38.

[0028] Arc-shaped limiting plates 38 are symmetrically arranged above the conveyor belt in conveyor 1. Arc-shaped limiting plates 38 are located at the feed inlet of cold ironing machine 2. Packaging materials constrained by arc-shaped limiting plates 38 enter the feed inlet of cold ironing machine 2.

[0029] When in use, the packaging material is placed on the conveyor belt in the conveyor 1, and after being limited and guided by the limiting structure 3, it enters the cold ironing machine 2 for cold ironing. The operator can manually adjust the spring preload by rotating the knob 34 to drive the threaded rod 33 to rotate according to the actual width of the packaging material to be processed, so as to adapt to packaging materials of different thicknesses and hardnesses.

[0030] The threaded rod 33 is driven to rotate by rotating the knob 34. When the threaded rod 33 rotates, it will generate displacement along the axial direction, which will push the adjusting plate 35 to move. When the adjusting plate 35 moves toward the arc-shaped limiting plate 38, the compression spring 39 is squeezed and stored, which can adjust the spring preload of the arc-shaped limiting plate 38 and adapt to packaging materials of different specifications and hardness.

[0031] Start the conveyor 1, and the packaging material to be processed is conveyed forward along the conveyor belt of the conveyor 1, gradually approaching the feed port of the cold ironing machine 2. When the edge of the material contacts the roller 381 on the inner wall of the arc-shaped limiting plate 38, the roller 381 rotates synchronously under the action of the material conveying friction. The rotation of the roller 381 converts the sliding friction between the material and the limiting plate into rolling friction, which greatly reduces the frictional resistance. At the same time, the anti-slip sleeve 382 prevents the material surface from being scratched or the conveying from being stuck due to slippage.

[0032] During the conveying process, the material exerts a lateral thrust on the arc-shaped limiting plate 38, compressing the compression spring 39. The compression spring 39 releases its elastic potential energy, which pushes the arc-shaped limiting plate 38 to fit against the material through the limiting of the guide rod 36. The arc-shaped limiting plate 38 always applies continuous and uniform elastic pressure to the edge of the material, realizing "adaptive limiting" to ensure that the material is always conveyed along the center line of the conveyor belt and avoids deviation. The guide rod 36 limits its sliding stroke in the guide hole 32 through the anti-detachment plate 37 to prevent the arc-shaped limiting plate 38 from detaching from the support plate 31.

[0033] After being constrained by the arc-shaped limiting plate 38, the packaging material enters the feed inlet of the cold stamping machine 2 to avoid processing defects such as misalignment of the cold stamping pattern and missing edge stamping due to material displacement.
