Description

Technical Field

[0001] The present invention belongs to the technical field of stamping equipment, and more specifically, particularly relates to a stamping equipment for packaging boxes. Background Art

[0002] With the development of society, the consumption side is constantly upgraded, and the competition in product promotion is becoming increasingly fierce. For consumers, the visual perception of the packaging box plays a great role in consumption decisions. Therefore, some packaging design companies have increasingly complex and more artistic design styles for packaging boxes. In order to highlight the three-dimensional effect of the packaging box pattern, some design companies will design packaging boxes with three-dimensional shapes, which poses new challenges to the production of packaging boxes.

[0003] For example, the printing and stamping equipment for the surface texture of packaging boxes with the application number CN202223600089.4 includes a carrying frame, a stamping component and a signal component. An installation hole runs through the middle of the carrying frame, and the stamping component and the signal component pass through the carrying frame from the installation hole. Installation blocks are rotatably connected to the shaft rod of the stamping component and the adapter rod of the signal component, and the installation blocks are detachably installed on the carrying frame.

[0004] Based on the retrieval of the above patent and the combination of the equipment in the prior art, it is found that in the existing stamping equipment, since it uses a roller pressing mechanism for stamping, if the movement speed of the paper is not adjusted properly, the pressing roller will generate a frictional component force in the front-back direction on the paper surface during the rotation and stamping process, and long-term operation is likely to cause misalignment of the paper at the bottom stamping.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a stamping equipment for packaging boxes is provided with the expectation of achieving a more practical value. Summary of the Invention

[0029] Example:

[0030] As shown in Figure 1 to Figure 3 shown:

[0031] The present invention provides a box - packaging stamping device, including:

[0032] The carrier 11, the pressing mechanism 12, the conveying unit 13 and the stamping die set 14;

[0033] At least one conveying unit 13 is respectively arranged at the front and rear sides of the carrier 11, and the conveying unit 13 is used to convey the packaging paper 18, and the packaging paper 18 is in close contact with the upper surface of the carrier 11;

[0034] The stamping die set 14 includes an upper die 141 and a lower die 142 . The upper die 141 is connected to the pressing mechanism 12 , and the lower die 142 is connected to the carrier 11 . The pressing mechanism 12 drives the upper die 141 to press down close to the lower die 142 to form stamping on the surface of the packaging paper 18 .

[0035] The technical solution of this embodiment abandons the roller pressing method of the prior art for embossing, and innovatively adopts the die stamping method for embossing, so as to effectively avoid applying stress in the moving direction to the paper surface during the embossing process, thereby avoiding the displacement of the paper during the embossing process, and further improving the embossing accuracy. During the embossing process, the upper die 141 and the lower die 142 only generate vertical stamping pressure on the packaging paper 18.

[0036] The conveying unit 13 includes a motor 131, a shaft 132 connected to the motor 131, a ring 133 sleeved on the shaft 132, and a gear 134 fixedly connected to the shaft 132. At least two rings 133 are arranged on the shaft 132, and a gap is reserved for the stamping to pass through the ring 133. The gears 134 on the two shafts 132 are connected to each other. The gear 134 rotates in the opposite direction of the motor 131, thereby driving the corresponding shaft 132 to rotate in the opposite direction, thereby driving the ring 133 on the shaft 132 to rotate. When the two rings 133 rotate, the wrapping paper 18 can be conveyed in one direction. The wrapping paper 18 is usually a finished product of a rolled wrapping paper roll, which is rotatably connected to a bracket, and then one end is inserted between the two rings 133 of the conveying unit 13 of the device.

[0037] At least one limiting plate 17 is disposed on both sides of the upper mold 141, and the limiting plate 17 is fixedly connected to the carrier 11, and the lower surface of the limiting plate 17 is in contact with the upper surface of the packaging paper 18. The limiting plate 17 further compacts the packaging paper 18 to improve the embossing accuracy.

[0038] A cavity 170 is provided in the limiting plate 17, and the limiting plate 17 is connected to an air suction unit;

[0039] The suction unit is a plurality of suction ports 171 arranged at the bottom of the limiting plate 17, the suction port 171 is connected to the cavity 170, the cavity 170 is connected to one end of the air pipe 173, the other end of the air pipe 173 is connected to the vacuum pump 172, and the middle of the air pipe 173 is connected to a pressure relief valve 174.

[0040] The vacuum pump 172 therein can evacuate the cavity 170, so that the multiple suction ports 171 can adsorb the upper surface of the wrapping paper 18.

[0041] Before stamping, the multiple suction ports 171 adsorb the upper surface of the wrapping paper 18, and then the upper die 141 presses down to the lower die 142 to stamp the wrapping paper 18 and form an embossed texture on the wrapping paper 18. After stamping, the vacuum pump 172 stops, and then the pressure relief valve 174 releases pressure, and the suction ports 171 release the adsorption of the wrapping paper 18.

[0042] The pressing mechanism 12 includes a cross frame 121, a guide sleeve 122 fixedly connected to the cross frame 121, a guide shaft 123 slidably connected to the guide sleeve 122, and a hydraulic cylinder 124 fixedly connected to the cross frame 121. The piston rod of the hydraulic cylinder 124 is fixedly connected with a pressing plate 15. The lower end of the guide shaft 123 is fixedly connected with the pressing plate 15. At least two guide sleeves 122 and guide shafts 123 are respectively provided, and the pressing plate 15 is connected to the upper die 141.

[0043] The cooperation between the guide sleeve 122 and the guide shaft 123 guides the movement of the pressing plate 15.

[0044] It further includes a magnet 16. Magnets 16 are fixedly connected to the pressing plate 15, the upper die 141, the lower die 142, and the carrier table 11. The pressing plate 15 and the upper die 141 are magnetically connected by a group of magnets 16, and the lower die 142 and the carrier table 11 are magnetically connected by another group of magnets 16.

[0045] The pressing plate 15 and the upper die 141 are magnetically connected, and the lower die 142 and the carrier table 11 are magnetically connected, so as to facilitate the disassembly and installation of the upper die 141 and the lower die 142.

[0046] It further includes a support member 10, and the pressing mechanism 12, the carrier table 11, and the conveying unit 13 are all installed on the support member 10.

[0047] The specific usage mode and function of this embodiment:

[0048] When the present invention is in use, the conveying unit 13 conveys the wrapping paper 18. When the wrapping paper 18 moves to a suitable position, the multiple suction ports 171 adsorb the upper surface of the wrapping paper 18, and then the upper die 141 presses down to the lower die 142 to stamp the wrapping paper 18 and form an embossed texture on the wrapping paper 18. After stamping, the vacuum pump 172 stops, and then the pressure relief valve 174 releases pressure, and the suction ports 171 release the adsorption of the wrapping paper 18. At the same time, the upper die 141 moves upward, and the conveying unit 13 continues to convey the wrapping paper 18 until the next stamping position of the wrapping paper 18 moves below the lower die 142. In this way, the wrapping paper 18 is continuously stamped in a cycle.
