Description

Technical Field

[0001] The utility model specifically relates to a plasma generator adjustment device for a folder-gluing machine. Background Art

[0002] At present, for paper packaging boxes, especially coated and gold and silver cardboard packaging boxes, plasma devices are needed to polish the glue of the packaging boxes when pasting them to promote the bonding strength of the glue. The principle is: when plasma meets the surface of the treated object, chemical reactions and physical changes occur. The glue surface is cleaned, hydrocarbon dirt is removed, the surface molecular chain structure is changed, and free groups such as hydroxyl and carboxyl are established. These groups have the effect of promoting adhesion of various coating materials, thereby achieving the purpose of preventing glue from debonding.

[0003] The plasma device includes a plasma generator, a gas delivery system and a plasma spray gun. The plasma spray gun is fixed between the paper feeding part and the gluing part of the automatic folder gluer. Since the folder gluer is used for a wide variety of packaging boxes, different products need to adjust the position of the plasma spray gun when gluing boxes to achieve the best processing effect. To this end, those skilled in the art have developed a plasma spray gun adjustment device for the folder gluer. For example, the utility model patent technology of the plasma polishing device of the folder gluer, which was published by the China Patent Office on February 27, 2018, with the authorization announcement number CN207044787U, includes a frame fixed between the paper feeding part and the gluing part of the folder gluer, and is characterized in that: a plasma spray gun with a nozzle facing upward is arranged on the lower side of the frame, and a positioning strip arranged horizontally along the conveying direction of the folder gluer is arranged on the upper side of the frame; a gap is arranged between the positioning strip and the plasma spray gun for paperboard to pass through.

[0004] The plasma spray gun adjustment device of the above structure has the following defects:

[0005] 1) The positioning strip is frictionally connected to the cardboard, which will cause certain wear and tear on the packaging box, and the insulating layer on the surface of the positioning strip will also be worn.

[0006] 2) The frame structure of the plasma spray gun is complex and inconvenient to use. For example, to adjust the left and right and up and down positions of the plasma spray gun, it is necessary to loosen the screws on the first set of blocks and the connecting blocks respectively. After the adjustment, the screws need to be tightened again. The steps are cumbersome, and the adjustment is completely dependent on manual adjustment. As a result, the machine operator needs to make multiple trial adjustments in the process of operating the plasma spray gun to the optimal position, which is inefficient. Utility Model Content

[0007] The utility model aims to provide a plasma generator adjustment device for a folder gluer, which utilizes a hand-cranked worm gear lifter to adjust a plasma spray gun and a positioning wheel set, is easy to operate, and improves efficiency; the positioning wheel set uses a positioning insulating wheel to position with a paperboard, and will not cause wear to the paperboard.

[0008] The utility model is realized by the following technical solutions:

[0009] That is, a plasma generator adjustment device for a folder gluer, comprising a body of the folder gluer, characterized in that a plasma generator adjustment mechanism is provided on the body below the paper, a cardboard wheel positioning adjustment mechanism is provided on the body above the paper, the plasma generator adjustment mechanism comprises a first Z-direction worm elevator perpendicular to the side of the body, a first Z-direction base parallel to the side of the body is provided at the front end of a lead screw of the first Z-direction worm elevator, a first X-direction worm elevator is provided at the outer end surface of the first Z-direction base, a first X-direction base is provided at the front end of a lead screw of the first X-direction worm elevator, a first Y-direction worm elevator is provided on the upper end surface of the first X-direction base, a first Y-direction worm elevator is provided vertically upward, a first Y-direction base is provided at the upper end of a lead screw of the first Y-direction worm elevator, and a plasma spray gun vertically upward is provided on the first Y-direction base;

[0011] The worm gear lift of the utility model is a mature commercial product of the prior art, which has the characteristic of self-locking. After the worm gear lift is used to adjust the position of the plasma spray gun and the positioning wheel group by hand crank (hand wheel or split crank), the position of the plasma spray gun and the positioning wheel group can be fixed without additional operation.

[0012] The worm elevator of the utility model preferably adopts SWL series worm screw elevator.

[0013] The lead screw of the first Z-direction worm gear lift is perpendicular to the side surface of the body of the folder gluer, and a through hole for the lead screw to pass through is arranged on the body corresponding to the lead screw.

[0014] The second Z-axis worm gear lift is preferably fixed to the other side of the machine body by a bracket.

[0015] The plasma generator adjustment mechanism and the paper wheel positioning adjustment mechanism of the utility model are respectively located above and below the paper, and they are independent adjustment mechanisms, which are easy to operate. In contrast, the authorization announcement number is: CN207044787U, and the utility model patent technology named plasma grinding device of folder gluer has a first fixing part and a second fixing part both arranged on the same fixing rod, and the plasma spray gun is located between the first fixing part and the second fixing part. Its structure is too compact and inconvenient to operate.

[0016] The positioning wheel set of the utility model adopts a row of multiple positioning insulating wheels. After contacting with the paper, the positioning wheels rotate, and the friction force on the paper is small, so the paper will not be worn.

[0017] The worm gear lift of the utility model is a mature commercial product with existing technology. Its structure is the same as the Chinese patent issued and disclosed on August 1, 2023, and the authorization announcement date is CN219449162U. It is called a worm gear lift with an internal screw. The drive shaft can be rotated by using a crank to achieve the extension and retraction of the screw.

[0018] Furthermore, the drive shaft of the worm gear lift of the utility model is provided with a split crank, which can be folded up when not in use to prevent accidental touching of the crank and misoperation.

[0019] Furthermore, the worm gear lifts of the present invention share one crank handle, and only one worm gear lift can be operated at a time. For example, it is stipulated in the system that adjustments must be made in the order of Z direction, X direction, and Y direction.

[0020] Furthermore, the axle of each positioning insulating wheel of the positioning wheel group of the utility model is connected to the wheel group bracket through a vertical connecting column, the front end of the wheel group bracket is provided with a through hole corresponding to the two vertical connecting columns at the front, the upper ends of the two vertical connecting columns are inserted into the through holes, and one side of the front end of the wheel group bracket is provided with a fastening bolt inserted into the through hole, and the upper ends of the remaining vertical connecting columns are fixedly connected to the wheel group bracket by welding.

[0021] That is, the heights of the two front positioning insulating wheels are adjustable. By adjusting the heights of the two front positioning insulating wheels, the inclination of the front end of the positioning wheel group can be adjusted, and the application range is wide.

[0022] The utility model has the advantages of reasonable structure, convenient operation and easy use. By using the utility model, the positions of the plasma spray gun and the positioning wheel group can be quickly adjusted by hand-cranking, and the grinding effect on the cardboard is good, ensuring that the glue at the glued edge does not come apart after the box is pasted.
