Description
Technical Field
The utility model belongs to the technical field of the carton and specifically relates to a used fabric wheel of carton folding department is related to.
Background
The paperboard is generally classified into honeycomb paperboard and corrugated paperboard, wherein the honeycomb paperboard is formed by bonding a first surface paper, a second surface paper and a honeycomb core; the corrugated paper board is made up by using face paper, liner paper, core paper and corrugated paper which are made into corrugated form through the processes of adhesion.
In the process of processing the paper board into the paper box, the pressing wheel is needed to press the paper board so as to form an indentation which is needed when the subsequent paper box is turned over or bent.
The design of the creasing wheel is related to the line shape of the paperboard creasing line, and the compressive strength of the corrugated paperboard and the honeycomb paperboard after box forming is influenced, so that the creasing wheel is particularly important.
The creasing wheel that traditional equipment manufacturer provided is the creasing wheel of single indentation usually, and this kind of traditional creasing wheel can only form a creasing line to the turn-ups department between cardboard apron and the cardboard curb plate for it is the same with the creasing line of external roll over use when the apron enstrophe, no matter so whether honeycomb cardboard becomes the case or corrugated container board becomes the case and can all cause the softening of carton turn-ups department after the apron once or several enstrophes or external roll over, and then reduced the compressive strength of carton, make the unable repetitious usage of carton.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide the used fabric wheel of a carton department of turning over, this fabric wheel forms the line ball that enables the apron and turn over a lot of on the carton, and can not reduce the compressive strength of carton yet, increases the rate of utilization of carton.
The utility model provides a technical scheme that its technical problem adopted is: including first fabric wheel and second fabric wheel, first fabric wheel is including the fabric axle that is used for the line ball, and second fabric wheel includes main line wheel and at least one leading wheel, and the height that highly is greater than the leading wheel of main line wheel.
The utility model discloses in adopt a double thread wheel to carry out the indentation processing to the cardboard, the apron of carton forms a main indentation in one side with the book department of turning over of curb plate, and direction indentation of a main indentation of opposite side, wherein the main indentation of both sides is located the position and differs, and the indentation that uses when making the apron enstrophe or folding outward like this is different for the apron can enstrophe or fold outward many times, can not reduce the compressive strength of carton.
In addition, the setting of leading wheel is on the one hand to play the guide effect to the thread wheel, and on the other hand can make the fabric pressing axle of a line wheel be located between thread wheel and the leading wheel for the cardboard can not squint at the line ball in-process, if first fabric pressing wheel and second fabric pressing wheel are the single line wheel, because not the one-to-one during that line ball, so probably unilateral perk, there is the risk of exploding the line.
Furthermore, the guide wheel is one, and the distance between the main wire wheel and the pressing line formed by the guide wheel on the paper board is one paper board thickness to three paper board thicknesses. Through experiments, the widths of the main wire wheel and the guide wheel are 2/3 of the thickness of the paper board, and a wire pressing shaft is required to be spaced between the main wire wheel and the guide wheel, so that the distance between the main wire wheel and the guide wheel for forming a pressing wire on the paper board is at least one paper board thickness; then, considering the pressure possibly from the first wire pressing wheel, the interval between the two is widened again to relieve the pressure, but the maximum thickness of the three paperboards is too large, and the main indentation distance formed by the main wire wheel and the wire pressing shaft is too large, so that the compression strength of the paperboards after box forming is reduced.
Further, the line ball axle is located between main line wheel and the leading wheel. So that two main indentations which do not correspond to each other are formed on both sides of the paperboard as indentation lines for the inward turning or the outward folding.
Furthermore, the pressing line depth formed on the paperboard by the first pressing line wheel and the main line wheel is 1/3-5/6 of the thickness of the paperboard. The thickness is selected so that the indentation can be pressed easily without causing line explosion, wherein if the line pressing depth is less than 1/3, the indentation is not obvious, and the line explosion caused by poor folding resistance is easy to occur in the carton forming process; if the score line depth is greater than 5/6, the score line will be too deep, which will result in large deformation of the paperboard near the score line and will also easily initiate the score line. The depth of the line pressing formed on the paperboard by the first wire pressing wheel and the main wire pressing wheel in the embodiment is preferably 2/3.
Further, the height difference between the main wire wheel and the guide wheel is 1/6-2/3 of the thickness of the paper board. The line ball degree of depth of leading wheel can not be too deep, misuse the crease when avoiding the cardboard to become the case, but the height of leading wheel and main line wheel again can not be poor too big, can not share the pressure of first line ball wheel otherwise.
Furthermore, the pressing line formed by the guide wheels is positioned on one side of the cover plate of the carton.
Furthermore, the pressing line formed on the paperboard by the first pressing line wheel is positioned on the outer side of the carton, and the pressing line formed on the paperboard by the second pressing line wheel is positioned on the inner side of the carton. The cover plate of the paperboard can be turned inwards or outwards to form an indentation which can be used independently, the strength of the turning part is guaranteed not to be damaged, and therefore the compression strength of the carton is not reduced.
Furthermore, the wire pressing wheel is arranged on the roller, and the wire pressing wheel is detachably connected with the roller. Make things convenient for the change of creasing roller, according to the different demands of production, can select corresponding creasing roller according to cardboard specification thickness to freely easily change the creasing roller through detachable device, adapt to the production requirement, it is easy and simple to handle simultaneously, very big reduction the cost of equipment.
Further, first fabric wheel includes first circular base and locates the fabric axle in first circular base middle part, second fabric wheel includes the circular base of second, and establishes the main line wheel and the leading wheel of the circular base both sides of second. The arrangement of the circular base can facilitate the connection of the first wire pressing wheel and the second wire pressing wheel with the rolling shaft.
Further, the paper board adopted by the paper box is a honeycomb paper board or a corrugated paper board.
The utility model has the advantages that:
1. the first wire pressing wheel and the second wire pressing wheel are used for pressing the inner side and the outer side of the cover plate of the carton, the pressing wires on the two sides are not overlapped, the difference between the pressing wires used when the cover plate of the carton is turned inwards and outwards is realized, the softening of the paper board at the turning position after the cover plate is turned for one time or two times is avoided, and the integral compressive strength of the carton is enhanced;
2. the guide wheel is arranged, the guide wheel can guide the main line wheel, and the main line wheel is prevented from deviating on the paper board.
