Description

Technical Field

[0001] The utility model relates to the technical field of printing and drying devices for packaging boxes, in particular to a printing and drying device for packaging boxes. Background Art

[0002] After the packaging box is produced, various texts and patterns need to be printed on it according to the needs of the company. Generally, the ink cannot dry quickly after printing. Putting the packaging boxes with undried ink together will easily cause the patterns and texts to become blurred due to friction. Therefore, the packaging boxes are dried after printing.

[0003] For example, the prior art Chinese patent publication number "CN220883771 U" discloses an ink drying device for packaging box printing, specifically relating to the field of printing drying technology. The device includes a metal drying device transmission bracket, a drying device housing disposed in the middle of the upper end of the drying device transmission bracket, and a drying ventilation duct disposed on the outer end surfaces of the drying device transmission bracket and the drying device housing. The inner end surface of the drying ventilation duct is provided with an air guide groove. In actual use, the present invention utilizes a guide protrusion to facilitate the diversion of air within the drying ventilation duct, thereby effectively drying the printed marks on the upper end of the packaging box.

[0004] Although most existing drying equipment has the ability to dry text and patterns on the surface of packaging boxes, it generally lacks the function of adjusting the position of the equipment shell to change the inlet and outlet heights. However, in actual operation, due to the diverse sizes of packaging boxes, the fixed inlet and outlet heights often limit the drying treatment of packaging boxes of certain specifications, thereby affecting the applicability and efficiency of the equipment.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0021] Reference Figure 1-5 , a printing and drying device for a packaging box, comprising a transport unit 1, a shell 11 is provided at the upper ends of the support frames on both sides of the transport unit 1, a cover body 12 is movably connected to the upper end of the shell 11, the cover body 12 and the shell 11 are fixed by a locking assembly 2, two relatively arranged pop-up assemblies 3 for popping up the cover body 12 are provided between the cover body 12 and the shell 11, a drying device 4 is fixedly connected to the lower end of the cover body 12, and a lifting assembly 5 for driving the shell 11 to move up and down is provided on both sides of the shell 11, wherein the transport unit 1 and the drying device 4 respectively include a conveyor belt, a motor, etc., as well as a fan, a heating wire, etc. The specific structure is the existing technology and will not be elaborated here.

[0022] In this embodiment, the shell 11 is a frame structure, and both sides of the transport unit 1 are fixedly connected with relatively arranged U-shaped plates 14. The shell 11 is movably connected to the inner sides of the two U-shaped plates 14. The upper end of the shell 11 is provided with a step 13, and the cover body 12 is clamped in the step 13. The shell 11 is movably connected in the two U-shaped plates 14, which not only can realize height adjustment, but also can guide and limit the movement of the shell 11. The cover body 12 is clamped in the step 13 and fixed by the locking assembly 2, which can facilitate disassembly and maintenance.

[0023] It should be noted that the locking assembly 2 includes a fixed block 21 fixedly connected to the upper end of the shell 11, and a positioning rod 22 passing through the fixing block 21. A spring 23 is fixedly connected between the positioning rod 22 and the fixing block 21. The other end of the positioning rod 22 is formed with a chamfer 24. When the drying device 4 needs to be repaired, it is only necessary to pull open the positioning rod 22 to remove it, which is convenient for the inspection of the drying device 4. Moreover, the chamfer 24 makes it unnecessary to pull open the positioning rod 22 a second time when the cover body 12 is re-engaged in the step 13, saving time.

[0024] Furthermore, the pop-up assembly 3 includes a contact plate 31 slidably connected between the inner walls of the shell 11, and two compression springs 32 embedded on both sides of the step 13. The lower end of the contact plate 31 is fixedly connected to two contact rods 33, and the contact rods 33 are fixedly connected to the compression springs 32. After the lock assembly 2 is pulled open, the pop-up assembly 3 is used to push the cover body 12 out of the step 13 to facilitate the removal of the cover body 12.

[0025] Among them, the two lifting components 5 include cylinders 51 arranged on both sides of the transport unit 1, one of the cylinders 51 is fixedly connected to the transport unit 1, and the other cylinder 51 is rotatably connected to the transport unit 1. The two sides of the outer shell 11 are respectively fixedly connected with a rotating part 52 and a fixed part 53. The lower end of the rotating part 52 is rotatably connected to the axial end of the cylinder 51, and the lower end of the fixed part 53 is fixed to the axial end of the rotating cylinder 51 through a positioning component 6, wherein the rotating cylinder 51 is rotatably connected to the transport unit 1 through a hinge.

[0026] On the basis of the above embodiment, the positioning assembly 6 includes a sleeve 61 sleeved on the axial end of the rotating cylinder 51, the axial end of the cylinder 51 is fixedly connected to a step 54, the lower end of the fixing member 53 is fixedly connected to a rod 55, the circumference of the rod 55 is provided with a positioning bead 56, and the circumference of the sleeve 61 is provided with a card hole 62 adapted to the telescopic end of the positioning bead 56, wherein the step 54 is to prevent the sleeve 61 from falling off upward, and the rod 55 is limited by the sleeve 61. When it is necessary to remove the cylinder 51 on this side, the positioning bead 56 is pressed down and then the sleeve 61 and the rod are connected. 55 is separated, the cylinder 51 can be turned over. When the drying device 4 needs to be inspected and repaired, the lower end of the shell 11 is lifted up by the cylinder 51 to exceed the U-shaped plate 14, and then the positioning bead 56 is pressed down and the sleeve 61 is separated from the insertion rod 55. Then the cylinder 51 is turned over to prevent the shell 11 from colliding with it when it is turned over. Then, the shell 11 is rotated to the side of the cylinder 51 fixedly connected to the transport unit 1 through the rotating part 52, and then the cylinder 51 is lowered to facilitate the removal of the shell 11 and the drying device 4. There is no need to stand on the transport unit 1 to disassemble the drying device 4, which is beneficial to protecting the safety of personnel.

[0027] Working method: During operation, the shell 11 is adjusted to match the height of the packaging box through the cylinder 51, and then the drying device 4 is started, and then the transport unit 1 is opened, so that the packaging boxes enter the shell 11 for drying in turn. When the drying device 4 fails, the cylinder 51 is used to lift the lower end of the shell 11 to exceed the U-shaped plate 14, and then the cylinder 51 rotatably connected to the transport unit 1 is lowered and turned over to the ground, and then the shell 11 is rotated to the side of the cylinder 51 fixedly connected to the transport unit 1 through the rotating part 52, and then the cylinder 51 is lowered, the shell 11 and the drying device 4 are taken out, and the drying device 4 is inspected. After the inspection is completed, the shell 11 is reinserted into the step 13, and then lifted up by the cylinder 51, and then rotated to its original position, and the cylinder 51 is controlled to descend and inserted into the frames on both sides of the transport unit 1, and then the cylinder 51 on the other side is lifted up, the sleeve 61 is plugged into the insertion rod 55, and the positioning bead 56 is snapped into the card hole 62.
