Description

Technical Field

[0001] The invention relates to the technical field of honeycomb paper manufacturing, and in particular to a multifunctional honeycomb paper die-cutting and stretching machine. Background Art

[0002] The shape of honeycomb paper evolved from the shape of honeycombs. Honeycombs in nature protect bees from laying eggs and hatching delicate larvae, so honeycomb paper uses the principle of honeycombs to protect items to achieve a safe and stable effect. Honeycomb paper is three-dimensional after being stretched and does not require any glue to stick, which is very convenient. After being stretched, honeycomb paper can not only be used to wrap items for buffering and protection, but also can be used for filling, filling the gaps between items to achieve an anti-seismic effect, and avoid damage caused by shaking during transportation.

[0003] For this purpose, it is necessary to develop a device specifically for producing honeycomb paper for use. For example, the utility model with publication number "CN110271228A" and titled "a knurling device for processing honeycomb-shaped kraft paper roll" discloses a knurling device for processing honeycomb-shaped kraft paper roll, including a frame, a feeding roller, two feeding cylinders, a deviation correction device, a main motor, a reduction wheel, a support roller, a die-cutting roller, a material collection system and a numerical control device; the frame is provided with a feeding roller movably arranged on the outer side of the feeding end, and an L-shaped feeding hook is arranged below each end of the roller shaft of the feeding roller, and its inner end is connected to the feeding cylinder, and a deviation correction device is arranged on the top of the frame; the frame is provided with a main motor, and the reduction wheel is respectively connected to the main motor and the support roller through a transmission belt; a die-cutting roller is arranged above the support roller, and a plurality of rows of die-cutting blades arranged at intervals are fixedly arranged on the roller surface of the die-cutting roller along the axial direction, and the die-cutting blades on adjacent rows are staggered, and the blades of the die-cutting blades are tilted along the radial direction of the die-cutting roller; the tail of the frame is provided with a numerical control device and a material collection system. Although the honeycomb paper can be produced, it needs to be stretched and expanded manually or with a stretching device (such as the publication number "CN216141010U", named "a honeycomb cushioning packaging material stretching device") to form the honeycomb paper, and then torn into the required length manually for use. The operation is relatively troublesome, time-consuming and labor-intensive, and it is easy to scratch the hands; or, sometimes the honeycomb paper needs to be mixed with other papers (white lining paper) for use, and the two papers need to be cut at the same time when cutting. If they are torn by pulling, the tensions of the two different papers are different, resulting in poor and uneven tearing effects, which affects the packaging effect. Summary of the invention

In this embodiment, the honeycomb paper material is preferably made of kraft paper, which has the advantages of wear resistance, tear resistance and water resistance. The lining paper is preferably made of snow pear paper, which has the advantages of flexibility, air permeability and durability.

[0031] The honeycomb die-cutting mechanism 2, the conveying mechanism 3, the stretching mechanism 4 and the cutting mechanism 5 are arranged in sequence on the frame 1, and the driving device 6 drives the honeycomb die-cutting mechanism 2 and the conveying mechanism 3 to work synchronously through the synchronous linkage component 7, and the synchronous linkage component 7 drives the stretching mechanism 4 to work through the speed change transmission component 8.

[0032] The honeycomb die-cutting mechanism 2 is used to die-cut a honeycomb pattern on kraft paper to produce honeycomb paper. Specifically, the honeycomb die-cutting mechanism 2 includes a die-cutting bracket 21, an upper roller 22, a lower round roller 23, a die-cutting drive wheel 24, a die-cutting gear 25, a die-cutting pinion 26, a first spring 27, a second spring 28, an adjusting screw 29, an adjusting ring 210 and a sliding shaft 211.

Specifically, the sliding rod 512 is arranged on the frame 1 at a position corresponding to the blade seat 58 and is parallel to the sliding rod 54. The sliding seat 511 is movably arranged on the sliding rod 512 and is provided with a round hole for the knife shaft 57 to extend into. The knife shaft 57 is inserted into the round hole to achieve movable assembly, and the knife shaft 57 is supported by the sliding seat 511 to improve working stability.

[0048] In order to limit the lateral movement range of the circular knife 52, sensing sheets are symmetrically arranged on both sides of the sliding seat 511, and a micro-groove photoelectric sensor adapted to the sensing sheet is arranged on the mounting seat. When the sliding seat 511 moves to a predetermined position, the sensing sheet just extends into the sensing groove of the micro-groove photoelectric sensor, and the sliding seat 511 stops sliding, thereby effectively limiting the lateral movement range of the circular knife 52.

[0049] Elastic rubber blocks are provided at both ends of the slide rod 54, and elastic rubber blocks are provided at both ends of the sliding rod 512, which can absorb the impact of the slide seat 53 and the sliding seat 511, and have a good buffering effect. An elastic rubber pad is provided between the transverse gear 56 and the circular knife 52, and the assembly is tight.

[0050] When cutting is required, the transverse motor 51 drives the knife shaft 57 to rotate through the gear set 510, and the knife shaft 57 drives the transverse gear 56 and the circular knife 52 to rotate. The transverse gear 56 and the transverse rack 55 cooperate with each other to achieve the goal of driving the circular knife 52 to move transversely while also synchronously driving the circular knife 52 to rotate for cutting, thereby achieving fast and efficient cutting operations, which not only improves work efficiency and reduces labor intensity, but also achieves higher cutting accuracy and ensures a smooth incision, thereby improving the packaging effect.

[0053] During operation, the kraft paper is guided through the honeycomb die-cutting mechanism 2, the conveying mechanism 3, the stretching mechanism 4 and the cutting mechanism 5 in sequence, and the lining paper is guided through the stretching mechanism 4 and the cutting mechanism 5. The honeycomb die-cutting mechanism 2 is used to die-cut a honeycomb pattern on the kraft paper to obtain the honeycomb paper 12; then the conveying mechanism 3 is sent to the stretching mechanism 4, and the speed difference is formed by the speed change of the speed change transmission assembly 8, so that the conveying speed of the stretching mechanism 4 is faster than the conveying speed of the conveying mechanism 3, so as to achieve the effect of stretching the honeycomb paper 12 to unfold. At the same time, the lining paper 13 is located on the stretched and unfolded honeycomb paper 12, so as to realize the overlapping composite lining paper 13, and then sent out from the cutting mechanism 5 together. When sent out to the required length, the lateral movement motor 51 is controlled to work, so as to realize the lateral movement of the circular knife 52 while rotating to perform the cutting action, so as to realize the cutting of the lining paper 13 and the honeycomb paper 12 together, and the incision is smooth, the cutting effect is good, and there is no need to pull and tear, which saves time and effort and improves work efficiency.
