Description

Positive press horizontal flat press flat die cutting and thermal printer

The invention discloses the horizontal platen printing packaging of the malleation machinery of a kind of cross cutting, thermoprint.

At present, commercially available die-cutting machine of China and thermoprinting machine are divided into horizontal and vertical two kinds, all be paper to be put into the moulded board interstation impress, pallet is fixed on the horizontal machine, the motion of following pallet, power source is passed to down pallet by main shaft, following pallet upwards with the last pallet of the fixing formation pressure that meets, be called counter-pressure, i.e. the bottom-up pressure of pressure.Paper is to be placed on the movable following pallet to be stamped; The paper of vertical machine, also be to be placed on above the movable pallet, be the fan shape moving pressing then, these two kinds of modes, because paper is not to be placed in the stable environment to be stamped, promptly paper is in unsteady state and is stamped, so, the location takes place paper is easily forbidden, and vertical machine is easy to cause that paper comes off, and causes the hand accident of pressing for picking up paper.Both are on version, and very some is yielded to, and truly have unreasonable part.

In order to overcome above-mentioned deficiency, automatic horizontal machine has adopted paper to unfold flattening mechanism, and semi-automatic vertical machine has adopted " safe thick stick " and photoelectric tube to do safeguard protection, meet accident when picking up paper in case come off at paper, but effect is all very limited.Horizontal cross cutting thermoprinting machine is also arranged, adopt down pallet to fix and to go up pallet movable, produce normal pressure, but its pressure is less, speed is lower, can not compare with aforesaid horizontal die-cutting machine.

It is big to the purpose of this invention is to provide a kind of pressure, speed height, the movable and fixing horizontal platen cross cutting of malleation, the thermoprint machinery of pallet down of last pallet.So-called " malleation " is meant that pressure, presses to down pallet from top to bottom.Can make under paper the resting on steadily that is stamped on the pallet, under stable status, be stamped.Thereby improve the quality of products, stop to press hand and hinder the hand accident.

The object of the present invention is achieved like this: this machinery has two parallel impression pallets, and following pallet and body connect firmly, and last pallet moves, four jiaos are equipped with guide rail, about guide rail, the i.e. both direction in length and breadth in front and back, with slide rail control, pallet is moved up and down along this slide rail.The plane is processed with dovetail groove on the last pallet, the dovetail wedge is contained in the dovetail groove, the gradient of wedge is got 1: 12～15 and is advisable, self-locking performance is good, the top of wedge is fixedly connected with bearing block, bearing links by the pair of bearings shoulder at bearing and eccentric main axis middle part, two pairs of bearing shoulders are arranged on the eccentric main axis, the pair of bearings shoulder at main shaft two ends is installed on the body wallboard by bearing, two pairs of bearing shoulders are eccentric state, when main shaft rotates, because eccentric existence, when the dovetail wedge band under the bearing block pallet and is moved up and down, and in last pallet dovetail groove, slide, have screw on the wedge, have slotted hole on the bearing block, fastening their bolt can move in slotted hole, adjust the position of wedge, the upper plate platform is risen or decline, promptly pressure can be adjusted as required, during as die-cutting machine, and can make tangential knife adjust to the required degree of depth (as the processing adhesive sticker) of cutting accurately.Thereby realized that pressure top-down " malleation " mode impresses.

Because down pallet is fixed, and must be to be parked in down on the pallet when paper is stamped, so paper is to carry out when being stamped, make the quality raising of paper impression under stable condition, the paper that also can not come off is hindered the accident of hand.

Analyze the situation of the normal pressure that eccentric shaft produced below with mathematical method, see figure (1).If plumb line is R, the line of centres of eccentric main axis shoulder is L, and scheming medium and small garden is a pair of shoulder that is installed in the eccentric main axis two ends on the body wallboard, big garden is a pair of shoulder at eccentric main axis middle part, under the driving of external force, main axis rotation produces vector power F, so, in fact eccentric shaft is a wedge shape power to the pressure of horizontal plane, sees figure (2), normal pressure N=F/Sina, the a angle is more little, the pressure N that is produced is big more, and when eccentric line L was tending towards overlapping with plumb line R, a was tending towards 0, see figure (3), it is infinitely great that the N value is tending towards, and this machine is when moment produces pressure N, and a is tending towards 0, so this structure can produce sizable pressure N.

When eccentric main axis drives with helical gear, because offset is little, eccentric throw is advisable velocity of rotation with 15～20mm can be very high, can equal or exceed the speed of the horizontal die-cutting machine of back-pressure.

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1, Fig. 2, Fig. 3 are eccentric main axis force analysis figure
