Abstract
The invention discloses a heat sealing upper mold pushing mechanism which comprises a mold frame used for installing a movable heat sealing upper mold. The heat sealing upper mold pushing mechanism is characterized in that side plates are fixedly arranged in the front of and at the back of the mold frame; the mold frame is vertically and movably arranged; a top plate is arranged above the mold frame and the side plates; air cylinders are arranged between the mold frame and the top plate; each side plate is provided with a guide piece for guiding the top plate to move up and down; a sliding base is fixedly arranged on the side face of each side plate; a sliding rod is arranged in each sliding base and slides in the left-right direction; pushing blocks are fixedly arranged at the bottom of the top plate; a crank is arranged between each pushing block and the corresponding sliding rod and arranged in a swinging mode on the corresponding side plate; the upper swinging end of each crank is connected with the corresponding pushing block, and the lower swinging end of each crank is connected with the corresponding sliding rod; the other end of each sliding rod is connected with an upper wedge block; a stopping block is arranged at the stroke terminal point of each upper wedge block and fixed to the corresponding side plate. According to the heat sealing upper mold pushing mechanism, the mold frame can move up and down during heat sealing operation, and thus packing materials with high height are allowed to pass smoothly; meanwhile, the mold closing force is large, the mold closing stroke is small, and the heat sealing upper mold pushing mechanism can be applied to heat sealing packaging equipment of which the activity spaces of upper molds are limited.
Description
Technical field
The present invention relates to a kind of heat sealed package equipment, be specifically related to a kind of heat-sealing patrix pushing mechanism of heat sealed package equipment.
Background technology
Increasing food need to carry out plastic film packaging in the market, opens up and down after plastic film will intermediate package thing covers and seal plastic film by heat seal die, makes that packing material is sealed to be enclosed in plastic film packaging. In prior art, heat seal die is in the time sealing work, it is generally fixed that heat-sealing the framed of patrix is installed, the problem occurring is like this: when the packing material in the middle of plastic film has high height (if packing material is fish bean curd, duck neck, betel nut etc.), plastic film by packing material in distraction procedure forward just most probably with the friction of colliding of framed bottom surface, cause plastic film to be cut by incised wound, cause packing defective, food and can not reach the requirement of guaranteeing the quality. In addition, the area of some packing materials is larger, needs very large mold clamping force when multiple packing materials seal simultaneously, and adopting at present maximum methods is to utilize supercharging bar linkage structure, utilizes small cylinder to promote link assembly connecting rod support in the time of matched moulds and directly realizes. But connecting rod directly needs the larger space of stroke up and down from bending to support, it is proper for heat-sealing counterdie, adopting supercharging bar linkage structure, because enough height space are often arranged at the bottom of equipment, and often height space is less on the top of equipment, it is strictly limited that instant heating is sealed up the activity space of mould, institute thinks raising mold clamping force, generally selects at present large model cylinder, and this is all unreasonable from cost, energy-conservation, size aspect.
Summary of the invention
In view of the deficiency that background technology exists, object of the present invention is intended to provide one framed moving up and down, the simultaneously little heat-sealing patrix pushing mechanism of the large mould-closing stroke of mold clamping force in the time of heat-sealing work.
The present invention implements by following technical solution:
Heat-sealing patrix pushing mechanism, comprise framed, the framed interior movable heat-sealing patrix of installing, it is characterized in that: framed front and back are provided with side plate, side plate is fixedly installed, framed up and down setting, framed, the top of side plate is provided with top board, between framed and top board, be provided with cylinder, cylinder upper end is connected with top board, lower end is connected with framed, side plate is provided with guide the up and down of top board is led, the side of side plate is fixed with slide, slide bar is done the slip setting of left and right directions in slide, the bottom of top board is fixed with pushing block, between pushing block and slide bar, be provided with crank, crank is done to swing and is arranged on side plate, the upper swinging end of crank is connected with pushing block, bottom moved end is connected with slide bar, the slide bar other end connects upper voussoir, the lower wedge block corresponding with upper voussoir is fixed on framed top, upper voussoir has wedge surface under direction low-angle down, lower wedge block has wedge surface on the low-angle being directed upwardly, upper voussoir stroke start position and lower wedge block up and down just to and wedge surface be in contact with one another, upper voussoir mutually staggers and reserves framed upwards activity space at stroke final position and lower wedge block, the position, stroke end of upper voussoir is provided with block, block is fixed on side plate.
Adopt after technique scheme, the present invention is framed moving up and down in the time of heat-sealing work, the large mould-closing stroke of mold clamping force is little simultaneously, operation principle of the present invention is: when matched moulds, cylinder is range, framed in lower position and top board at upper limit position, now go up voussoir stroke start position and lower wedge block up and down just to and wedge surface be in contact with one another, because wedge surface has low-angle (being less than 15 degree with horizontal sextant angle), upper and lower scarf joint after touch pressure angle is little and can produce relative self-locking, bear larger mold clamping force so framed, but height stroke can be very little, after moving on heat-sealing patrix has been moved in heat-sealing, the push rod of cylinder starts retraction action, due to framed downward limited and framed Heavy Weight, so framed motionless and top board is action downwards, pushing block is by crank band moving slide-bar, slide bar drives upper voussoir to move to stroke end locality, in the time that upper voussoir arrives position, stroke end, the locking that offsets of the side of upper voussoir and block, so top board can not move down again, along with the continuation retraction of cylinder push-rod, now can only drive framed upwards action (upper voussoir and lower wedge block mutually stagger and reserved framed upwards activity space), due to framed upwards action, so can allow there is high height packing material smoothly by and can not collide with framed bottom, selecting of cylinder only needs to pull framed and corresponding connector simultaneously, cylinder model is available very little. in sum, the present invention is framed moving up and down in the time of heat-sealing work, allows the packing material with high height pass through smoothly, and the large mould-closing stroke of mold clamping force is little simultaneously, applicable to the limited heat sealed package equipment of patrix activity space.
As preferably, the bottom of pushing block is provided with pushing block groove, and movable the insertion in pushing block groove of upper swinging end of crank forms and be connected with pushing block, and slide bar is provided with slide bar groove, and the bottom moved end of crank is movable inserts that slide bar groove is interior to be connected with slide bar formation. Slide, slide bar and crank are arranged with respectively four groups in all around of front side board and back side panel. Cylinder upper end is cylinder block, and cylinder lower end is cylinder push-rod.
