Description

Technical Field

[0001] The utility model relates to the technical field of indentation of paper packaging boxes, in particular to an indentation device for paper packaging boxes. Background Art

[0002] Paper packaging boxes are a type of product widely used in the fields of gifts, food, cosmetics, electronic products, etc. They are mainly made of paper and are used to package various commodities.

[0003] The processing flow of paper packaging boxes is generally as follows: first, the packaging paper raw materials are selected, and then the packaging paper raw materials are cut into cardboard bodies of the required design size through a cutting device. Next, the cut cardboard bodies will be printed and dried on the surface. After completion, the cardboard bodies will be creased. Later, they can be bent into paper packaging boxes and put into storage for later shipment.

[0004] At present, the existing cardboard body creasing device for paper packaging boxes generally presses the cardboard body through a clamping structure before creasing. This method has weak stability and is prone to the cardboard body slipping on the creasing table, which greatly reduces the stability of the creasing process of the cardboard body creasing device for paper packaging boxes.

[0005] In addition, the creasing knife is easy to wear and age after long-term use and needs to be removed and replaced with a new one. However, the existing creasing device for the cardboard main body of the paper packaging box is mostly installed with screws. When disassembling, it is necessary to use a screwdriver to continuously turn the screws to remove each screw, and then the creasing knife can be removed. Later, it is also necessary to perform troublesome installation, which greatly reduces the convenience of disassembling and assembling the creasing knife on the cardboard main body creasing device for the paper packaging box.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 A creasing device for a paper packaging box includes a creasing platform 1, a negative pressure suction hole 11 is opened on the creasing platform 1, a longitudinal cylinder 12 and a platform leg 2 are provided on the creasing platform 1, a bottom plate 21 is provided on the platform leg 2, a negative pressure pump 22 is provided on the bottom plate 21, an exhaust pipe 23 and a connecting pipe 31 are connected to the negative pressure pump 22, a negative pressure suction cover 3 is provided on the connecting pipe 31, a vertical cylinder 13 is provided on the preset slide of the longitudinal cylinder 12, a horizontal cylinder 14 is provided on the vertical cylinder 13, a motor 15 is provided on the preset slide of the horizontal cylinder 14, and a knife seat 4 is provided on the motor shaft of the motor 15;

[0028] The knife seat 4 is provided with a mounting groove 41 and a damping hole 42. The mounting groove 41 is provided with a creasing knife 5. The creasing knife 5 is provided with a damping slot 51.

[0029] There are pull handles 6 on both sides of the knife seat 4, and the pull handle 6 is provided with an insertion rod 7 and a spring seat 8. The insertion rod 7 is provided with a magnetic block 71, and the spring seat 8 is provided with a spring 81. The pull handle 6 is provided with an elastic sleeve 61, and the longitudinal cylinder 12 and the transverse cylinder 14 are rodless cylinders, which are existing technologies.

[0030] The negative pressure suction holes 11 vertically penetrate the indentation platform 1 and are connected to the inner cavity of the negative pressure suction cover 3. The negative pressure suction holes 11 are arranged in nineteen groups horizontally, and each group consists of twenty-six holes arranged vertically. The cardboard body to be indented can be stably sucked with negative pressure on the entire bottom.

[0031] The negative pressure suction hood 3 is a rectangular hood-shaped structure as a whole and is connected to the connecting pipe 31. The negative pressure pump 22 is arranged in the central part of the bottom plate 21. The negative pressure pump 22 is a powerful suction pump.

[0032] There are two pull handles 6 that are symmetrical on the left and right. The mounting groove 41 passes through the knife seat 4 longitudinally and is inserted into the indentation knife 5. The pull handle 6 is an arc-shaped structure as a whole. The magnetic block 71 is magnetically adsorbed to the insertion rod 7. The magnetic block 71 is an artificial magnet and can achieve stable magnetic adsorption with the metal insertion rod 7.

[0033] The insertion rods 7 are divided into two groups that are longitudinally symmetrical. The insertion rods 7 pass through the damping openings 42 and are squeezed and plugged into the damping slots 51. The side cross-sections of the damping openings 42 and the damping slots 51 are both rectangular structures. The inner walls of the damping openings 42 and the damping slots 51 are provided with a silicone damping coating, which further improves the damping and anti-slip stability of the insertion rods 7 when they are inserted.

[0034] The spring seat 8 and the spring 81 form a group, which are two symmetrically arranged groups. The two ends of the spring 81 are fixed to the spring seat 8 and the knife seat 4 respectively. The spring 81 is highly elastic and stable.

[0035] The elastic sleeve 61 is evenly arranged along the outer wall of the handle 6. The elastic sleeve 61 is made of TPE plastic pad material and has a thickness of 15 to 20 mm. The TPE plastic pad material has excellent high elasticity, which improves the comfort of the hand pulling the handle 6.

[0036] Working method: Place the cardboard body to be indented horizontally on the indentation table 1, and then start the negative pressure pump 22, which will form a strong negative pressure suction force in the connecting pipe 31 and the negative pressure suction cover 3. Combined with each negative pressure suction hole 11, the cardboard body to be indented can be stably sucked with negative pressure on the bottom of the entire body, avoiding the cardboard body from slipping on the indentation table, thereby improving the stability of the indentation process of the cardboard body indentation device for paper packaging boxes;

[0037] The creasing operation can be performed by starting and combining the longitudinal cylinder 12, the transverse cylinder 14 and the motor 15 to adjust the position where the upper creasing knife 5 needs to be creasing, and then starting the vertical cylinder 13 to drive the creasing knife 5 to move downward and perform the creasing operation on the cardboard body below, which is the existing technology.

[0038] In addition, the indentation knife 5 is worn and aged after long-term use and needs to be disassembled and replaced with a new one. Start the vertical cylinder 13 to drive the indentation knife 5 to move downward. When the lower end surface of the indentation knife 5 contacts the indentation platform 1, stop the vertical cylinder 13, and then hold the pull handles 6 on both sides with both hands at the same time and pull them outward to drive the insertion rod 7 to exit the damping slot 51. At this time, the spring 81 is stretched and deformed, and then the worn and aged indentation knife 5 is pulled out longitudinally along the installation slot 41, which can be easily removed. Then take the new indentation knife 5 and insert it longitudinally into the installation slot 41, and then loosen the pull handle 6. The spring 81 pulls back and drives the insertion rod 7 to be quickly inserted into the damping slot 51, and the quick installation is completed, which improves the convenience of disassembly and assembly of the indentation knife 5 on the negative pressure suction cover indentation device of the cardboard body for paper packaging boxes.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
