Description

Novel Thistle board cutting machine

Technical field

The utility model belongs to a kind of special equipment on the Paper-faced gyp board assembly line, particularly a kind ofly is used for the Thistle board cutting machine that Thistle board rapidly and efficiently cuts off.

Background technology

In the Thistle board production process, need carry out online customized cut-off to still undried Thistle board after the moulding, send into drying machine then.Cutting machine is one of gypsum board production line key equipment.

In process of production, for reducing the slitter edge of finished product sawing, cut the waste.After the plasterboard cutting machine cuts off plate, require the plate shearing length to want accurately, and the edges of boards otch will try one's best vertically, this just and the transmission accuracy of cutting machine transmission system and upward lower cutter spacing, relative rotation have much relations.

Plasterboard cutting machine transmission spur gear originally, and lubricating condition is relatively poor, need shut down when lubricated and open protective cover, smears lubricating grease; So travelling gear is easy to wearing and tearing, is easy to generate the gap in the transmission system transmission process, transmission accuracy is not high, and it is not high to cause plasterboard to cut off precision; Add, the adjustment of upper and lower cutting knife spacing and relative rotation is very inconvenient, must shut down during adjustment; open protective cover, unclamp bolt, fastening again after the adjustment; quite trouble is unfavorable for steady production, is not suitable for large-scale Thistle board Production Line demand.

The utility model content

The purpose of this utility model provides a kind of novel Thistle board cutting machine, it can further improve the cut-out precision of Thistle board cutting machine, and make the relative position of lower cutter get final product online adjustment by handwheel, easy to adjust quick, to adapt to large-scale Paper-faced gyp board assembly line.

Its technical solution is as follows:

In order to achieve the above object, the technical scheme taked of the utility model is:

Novel Thistle board cutting machine, it comprises upper and lower cutter shaft and is oppositely arranged on upper cutter and lower cutter on the upper and lower cutter shaft, last idle wheel and following idle wheel drive cutter shaft by upper and lower break bar respectively and rotate, upper and lower cutter shaft is furnished with knife rest respectively, upper and lower cutter shaft is separately positioned on the upper and lower knife rest, the both sides of knife rest are respectively equipped with screw, screw body, and above-mentioned screw mandrel is furnished with handwheel, above-mentioned up and down idle wheel and up and down break bar be helical gear.

As improvement of the present utility model, last idle wheel is furnished with lead screw shaft, and handwheel is fixed on an end of lead screw shaft, and the screw that is fixed on the frame is screwed on the lead screw shaft.

The beneficial effects of the utility model comprise:

1. change cutting machine transmission spur gear into helical gear, and be provided with a plunger type grease pump on the cutter shaft down, this oil pump is not established motor in addition, power is from the rotation of cutter shaft down, the work of oil pump is synchronous with the cut-out action, oil pump work during cut-out, and oil pump also quits work when stopping to cut off, move very reliably, transmission accuracy and stability thereof are greatly improved;

2. redesign cutter guiding mechanism up and down utilizes lead screw transmission that the rotation of handwheel is changed into the swing of knife rest, to change the distance of cutter up and down; Utilize the helical gear transmission that the rotation of handwheel is changed into upper slitter with respect to the rotation of cutter certain angle down, align so that go up lower cutter.Like this, the relative position of last lower cutter can be adjusted easily.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the utility model cutter spacing part-structure schematic diagram up and down;

Fig. 4 is the utility model structural representation of cutter relative rotation part up and down.

The specific embodiment

Motor 20 drives driving gear 19 rotations, pass to knife shaft gear 6, following knife shaft gear 7 rotatablely moving by idle wheel 1,2, upper and lower cutter shaft 8,9 is connected with knife shaft gear key up and down, upper and lower cutting knife 10,11 is fixed on the upper and lower cutter shaft 8,9, upper and lower like this cutting knife 10,11 is also done reverse rotatablely moving mutually thereupon, when upper and lower cutting knife 10,11 rotates to the position that is in contact with one another, the plasterboard 17 in just will moving cuts off.And the rotor that is fixed on down the grease pump 12 on cutter shaft 8 spindle noses also rotates along with the rotation of following cutter shaft 9 simultaneously, so oil pump is just worked with the work of transmission system, guarantees cutting machine continuous lubricating oil in entire work process.

In the cutting machine course of work; as the otch of finding plasterboard 17 is not good; a kind of control method is to regulate the spacing of cutter up and down; during adjusting; need not shut down; the handwheel 13 in the direct-on-line rotary frame outside; 14; 3 or 4; screw 131; 141; 31 or 41 just move ahead or retreat, and (handwheel is connected with the leading screw key, and nut is screwed on the leading screw; owing to limited the rectilinear motion of leading screw and rotatablely moving of nut during design; so, rotatablely moving of leading screw just can change into the rectilinear motion of nut) when screw 131; 141 when moving ahead, and allow screw 31; 34 retreat; the cutter shaft support 15 like this; 16 just by screw 131; 141 push the left side to; otherwise just be pushed to the right, so, cutter shaft support 15; 16 just can be with the centre of gyration 17; 18 is suitable; be rotated counterclockwise; on cutter shaft support about cutter shaft is connected up and down; cutter is fixed on up and down on the cutter shaft up and down, as shown in Figure 1, on; following cutter just can move up and down; near or away from, the spacing of cutter is just set up up and down.

In the cutting machine course of work, not good as finding plasterboard 17 otch, second kind of control method is to regulate the corner of upper slitter with respect to following cutter.During adjusting; need not shut down equally; adjusting handle 5; handwheel 5 is fixed on an end of lead screw shaft; the screw 51 that is fixed on the frame is screwed on the lead screw shaft; so lead screw shaft just moves back and forth while rotating; because idle wheel 1 is connected in the other end of lead screw shaft; the reciprocating motion of leading screw has just passed to idle wheel 1; idle wheel 1 and idle wheel 2; last knife shaft gear engagement, idle wheel 2 and following knife shaft gear engagement, following knife shaft gear is by cutter shaft and driving gear are connected with reductor down; so when reducing motor does not start; idle wheel 2 does not rotate, owing to idle wheel 2 does not rotate, and idle wheel 1; 2 all is helical gear; so with the idle wheel 1 of idle wheel 2 engagement in reciprocating; can rotate simultaneously, rotate a certain angle with respect to following cutter shaft so just can drive cutter shaft, upper cutter is with respect to angle of lower cutter rotation; last lower cutter just can align, and has reached the purpose of adjusting.

Because all adjusting handles all are contained in the outside of support, regulate very convenient fast, even aborning, look for one to cut off the interval and just can adjust.

So the utility model is with can be used on the large-scale Paper-faced gyp board assembly line, steady production greatly improves the cut-out precision of plasterboard, shortens slitter edge, cuts the waste.
