Abstract

The utility model discloses an automatic branding machine for thin pieces of wood which is composed of a motor, a belt, a belt wheel, a crank block, a feeding mechanism, a material bin, and an electrothermal branding head. The utility model is characterized in that the feeding mechanism is formed by adopting a rack-and-gear driving a scraping wings; the positioning of platform workpiece is additionally provided with a workpiece automatic gauge compensation mechanism composed of a pressure plate, a pushing block, and a wedge. The utility model has the advantages of quick branding speed and even color of branding picture and text.

Description

Automatic branding machine for thin pieces of wood

The utility model relates to a kind of automatic branding machine at timber or similar material product surface branding literal or pattern.

At present, some manufacture the enterprise of woodworks such as ice cream stick, bamboo wood chopsticks, disposable wooden medical spatula specially, in order to improve product specification, brand various literal or pattern as required on the surface of wood chip.The wood chip of the Taiwan-owned enterprise in continent " fragrant forest Products Co., Ltd " public use automatically the branding machine be by motor after belt and big small belt pulley and gear reduction slow down, You Qu Bing slide block mechanism becomes rotation the straight reciprocating motion up and down of slide block again, the wood chip that slide block drives in the feed mechanism promotion feed bin that is made of wedge mechanism is located to the workpiece location of platform, be fixedly mounted on the electric heating branding head on the slide block owing to drive by slide block together, guaranteed that feeding and branding carry out synchronously with the wedge feed mechanism.There are 2 deficiencies in this automatic branding machine: the one, and wedge is limited by width, can only be to workpiece feeding longitudinally, stroke is longer, causes the branding speed of machine lower, maximum 60 of general per minute; The 2nd, because the stroke of electric heating branding head is changeless, and each wood chip of being branded is owing to be subjected to the limited thickness of material inhomogeneous, general existence ± 2mm error, therefore the drafts of punching block on the wood chip surface of electric heating branding head do not wait, the picture and text irregular colour that causes branding out on each wood chip is spared, and is deep mixed.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of branding speed fast, and the uniform wood chip of branding picture and text color is branded machine automatically.

For achieving the above object, the technical solution adopted in the utility model is: feed mechanism adopts slide block to drive a perpendicular tooth bar, this perpendicular rack drives gear, and gear drives a horizontal rack again, and an end of horizontal rack is fixing can be along the scraping wings of workbench slip; Place, workpiece location at platform sets up the thickness of workpiece compensation mechanism, this mechanism is by the holding pad that is fixed on above the platform, can slide up and down along the slide opening that platform is offered, bottom jacking block in the slope, match with inclined-plane, this jacking block bottom and by spring be positioned at block on the said horizontal rack and control its drift that moves back and forth and constituted.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the utility model along the cutaway view at center, place, workpiece location, and Fig. 2 takes away left view behind the feed bin for Fig. 1.

In conjunction with Fig. 1 and Fig. 2, structure and operating principle that the wood chip that the utility model provides is branded machine automatically are: motor 21 is through belt 25 and big small belt pulley 26, slow down through gear reduction 27 again after 24 decelerations, then through crank slide block mechanism 28,10(11 is the reduction gear box balladeur train of holding concurrently) rotational transform is become slide block straight reciprocating motion about in the of 10, fixing by heating 8 on slide block, heating copper stamen 9, punching block 12, thermocouple 29, the electric heating branding head that set bolt 6 and shell 7 are formed, the bottom of slide block 10 is fixed with the perpendicular tooth bar 20 that pumps with it, should pass the platform 15 that supports by frame 1 by perpendicular tooth bar, and be meshed in the gear 19 that is fixed on the platform bottom, gear 19 is meshed with horizontal rack 23 again, one end of this horizontal rack can be along the scraping wings 3 of platform slip by trimming bolt 2 fixed installations, pumping by above-mentioned rack pinion transmission scraping wings of slide block along the platform front-rear reciprocation movement, thereby the wood chip 5 in the feed bin 4 that is installed in its place ahead is pushed to one by one the place, workpiece location of corresponding electric heating branding head on the platform, and be located by being fixed on this flute profile holding pad 13 above place's platform, on the platform below the workpiece, have slide opening, jacking block 14 is housed in the slide opening, angle of friction according to steel part is 6 degree, angle adopts the 4-6 degree between the inclined-plane, bottom of jacking block 14 and the platform table top, the drift 18 that matches with it like this can be realized self-locking when compressing, the drift 18 that can slide along the platform bottom surface is by the spring 17 that is positioned at the one end and block 22 its reciprocating motions of control that are fixed on above-mentioned horizontal rack corresponding site.

The synchronous working process of entire machine is: when slide block rises, electric heating branding head rises, rack pinion transmission scraping wings moves to feedstock direction (among the figure to the right), wood chip is shifted onto place, workpiece location, meanwhile, block 22 moves right with horizontal rack 23, drift 18 is got, jacking block 14 is by gravity fall, the wood chip that branding is good is in relaxed state, the wood chip of newly being sent here is released the place, location, fall along blow tank 16 at last, when feeding finishes, slide block moves downward, drive horizontal rack to left movement, scraping wings is return original position left, block leaves drift with horizontal rack, the elastic force of spring 17 promotes drift and moves to left, and with the jacking block jack-up that makes progress, the wood chip that the end face of jacking block will place is upwards exerted pressure, wood chip is clamped between jacking block and the holding pad 13, although each dried thickness is inhomogeneous, its upper surface all can keep on the inside groove with holding pad 13 plane consistent, thereby has realized the automatic compensation of thickness of workpiece, the punching block of branding head is not changed because of dried thickness is different at the drafts of wood chip upper surface, guarantee the picture and text shade uniformity of branding on the wood chip.The scraping wings of this branding machine can do broad, workpiece is taked horizontal feeding, stroke shortens, and makes the branding speed of machine can bring up to 100 of per minutes, improves nearly one times than prior art.
