Description

The hob type trimmer

The utility model relates to a kind of accessory device of colour photograph visiting card machine industry special equipment, relates to the paper cutting apparatus of colour paper coil paper furtherly.

At present, the paper cutting apparatus that cuts colored coil paper in the colour name card machine industry is to adopt traditional old-fashioned hand papercutter.Because working environment is in the darkroom of or use colorful safety lamp black entirely at dark place, when cutting printing paper, the operator needs the plug positioning baffle to adjust the location of required size, and speed is slow and inconvenient, needs simultaneously to push down printing paper with left hand, so that fixing fixed size positions, the right-hand operated hand papercutter cuts printing paper, and cutting speed is low, and labour intensity is big, printing paper kerf quality and dimensional discrepancy are difficult for guaranteeing poor stability when especially operating.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, bears against contact printing paper and provide a kind of by bed plate and hobboing cutter, and is furnished with automatic pressboard and the hob type trimmer of the location plate washer that slides, make and cut steadily, speed is determined, locate light, the precision height.

The purpose of this utility model is achieved in that it comprises two supports installing on the base plate, paper platform, positioning baffle and mechanism for cutting sheet, float on the support and place winding shaft, one side of paper platform is provided with the paper feed frid, its feature is that two hobbing cutter supports that are used for fixing slide-bar also are housed on the base plate, the hobboing cutter device slides on slide-bar, above-mentioned mechanism for cutting sheet is the hobboing cutter of installing by in the hobboing cutter device, compress rubber tire, fixing bed plate and use pin on the paper platform, spring is located and is formed with the pressboard of the parallel placement of bed plate, bed plate and hobboing cutter closely bear against contact, the location ball is installed in the positioning baffle bottom surface, base plate is provided with a plurality of locating holes, and the notch periphery of paper feed frid is a convex.

The utlity model has following advantage:

1. adopt the positioning baffle bottom surface that the structure of location ball is installed, can locate during the slip positioning baffle, the positioning accuracy height is fast light.

2. mechanism for cutting sheet is furnished with automatic pressboard, and cutting force is reasonable when cutting, and the otch of printing paper is level and smooth, and the speed of cutting a sheet of paper improves more than two times than prior art.

3. adopt the roller mechanism for cutting sheet, simple in structure, easy to operate, blade is not fragile, and the dismantled and assembled mill that changes, and guarantees the security that the operator operates in the darkroom simultaneously.

4. remove main shaft, hobboing cutter, cutter shaft, spring, the making of pin employing metal material, paper platform, base plate adopt outside the producing wood, and remaining parts all adopts plastic production.Alleviate product weight, reduced product cost.

5. support is movable, can cut the colored coil paper of two kinds of international standards, and can load and unload, and is convenient to packed and transported and carries.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 3 hob type trimmer front view

Referring to Fig. 1, Fig. 3, two supports 2 are screwed respectively on base plate 9, and one of them support 2 can be fixed on two positions, the distance between the two stands can be changed, to cut the coil paper of two kinds of different in width respectively.Winding shaft 1 is floating to be placed on the U-shaped translot of support 2, can freely rotate, and play all around.Paper platform 4 is screwed with base plate 9, and paper feed frid 3 is screwed in the side of paper platform 4, and the notch of paper feed frid 3 periphery adopts convex, and printing paper is unobstructed harmless when passing paper feed frid 3.Two hobbing cutter supports 5 are screwed on base plate 9, and they are fixing with slide-bar 11, and hobboing cutter device 6 can horizontally slip on slide-bar 11.Connect on the base plate 9 two be parallel to each other and and base plate 9 between leave the guide plate 10 in gap, positioning baffle 7 can slide on base plate 9 along two guide plates, 10 formed slideways, location ball 25 is equipped with in the bottom surface of positioning baffle 7, during slip, 5 locating holes 8 of setting are meshed respectively on location ball 25 and the base plate 9, and positioning baffle 7 can be located, to cut 5 kinds of different-sized color printing paper respectively, the positioning accuracy height is swift to operate light.

Referring to Fig. 2, hobboing cutter device 6 is hobboing cutters 12 of being installed successively by hobboing cutter device housing 19 and inner chamber thereof, compress rubber tire 13, pad 14, positioning sleeve 15, cutter shaft 16, pad 20 and spring 21 constitutes.One of paper platform 4 is rectified fixedly bed plate 23 of face, and spring 21 bears against hobboing cutter 12 and bed plate 23 together tightly.During work, hobboing cutter 12 rolls on the one hand and cuts, and does relative friction contact with bed plate 23 on the other hand.Pressboard 17 is corresponding to bed plate 23 parallel installations, and pin 24 location that spring 22 is housed in two ends usefulness.Before cutting, hobboing cutter device 6 compresses rubber tire 13 and is separated with pressboard 17 at an end of slide-bar 11, and pressboard 17 is upspring under the effect of spring 22, and forms the gap of 3～4mm between the bed plate 23, and coil paper passes through betwixt.Behind definite printing paper required size, promote hobboing cutter device 6, compress rubber tire 13 and depress pressboard 17, printing paper is compacted immediately, and hobboing cutter self rolls, and with bed plate 12 contacts, cuts printing paper simultaneously.During cutting, cutting force is reasonable, printing paper otch smoothing regulation.Cut finish after, compress rubber tire 13 and separate again with pressboard 17, formed the paper gap again, continue mobile printing paper, carry out continuous cut paper.Easy to operate, speed is fast, especially guarantees the security that the operator operates in the darkroom.

Paper platform 4 and base plate 9 adopt producing wood, and at the thick black plastic plate of its surperficial paste List 2mm, except that main shaft 11, hobboing cutter 12, cutter shaft 16, spring 21 and 22, pin 18 and 24 adopt the metal making, remaining parts all adopts plastic production, this hob type trimmer whole smooth, glossy, in light weight.

The hob type trimmer is simple in structure, the dismantled and assembled mill hobboing cutter that changes.Support 2 can load and unload, and packing is light and handy, is easy to carry.
