Description

A kind of hot melt adhesive upper tenderizing machine

Technical field

The utility model relates to shoe-making field, in particular to a kind of hot melt adhesive upper tenderizing machine.

Background technique

The shoes worn in our daily lifes all include sole and shoe last surface.According to footwear styles difference, as leather shoes, The material of cloth shoes etc., shoe last surface is also different.But the material of most of shoe last surfaces is all by surface layer and liner at least materials at two layers It is combined.The mode of common connection different materials is bonded using hot melt adhesive, and material can be kept smooth docile.But It is that glue dries rear upper-shoe face would generally be harder, needs in the fixed process of the subsequent shoe last surface shoe style of progress first by shoe last surface Softening.Here would generally practical tenderizing machine, the working principle of common tenderizing machine on the market, there are mainly two types of: first is that using wet The mode of hot steam ironing softens shoe last surface；Another kind is softened using electric heating form heating shoe last surface, this mode Heating speed is very fast, and heating temperature can be adjusted according to different vamp materials.

Existing tenderizing machine, as shown in Figure 1, mainly including rack 1, upper pressure component 2 and lower clip assembly 3, upper pressure component 2 Including upper die 21, drive the first driver 23 of upper die slide downward and the electrical bar that is arranged in upper die, lower folder Component 3 includes the gas for being fixed in die holder 31, two lower clamp formwork 32, the driving lower clamp formworks 32 being hinged on die holder of rack and rotating Cylinder, heating cushion and elastic cushion 35, rack 1 close to the position on ground be provided with as upper die 21 and lower clamp formwork 32 it is mobile and Control the pedal 4 of heater switch.

But this hot melt adhesive upper tenderizing machine is in use, need that shoe last surface is manually put into upper pressure component 2 and lower folder group Between part 3, in the process, once accidentally touching pedal 4 is it is possible that operator's clamp hand or hot situation.

Utility model content

The purpose of the utility model is to provide a kind of hot melt adhesive upper tenderizing machines, and the safety of operation can be improved.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of hot melt adhesive upper tenderizing machine, including rack, upper pressure component and lower clip assembly, upper pressure component include that sliding connects The first heating for connecing upper die on the rack, driving the first driver of upper die slide downward and being arranged in upper die Part；Lower clip assembly include the die holder for being fixed in rack, two be hinged on die holder lower clamp formworks, driving lower clamp formworks rotation second Driver is fixed in the second heating member and the elastic cushion being fixed between two lower clamp formworks, lower clamp formwork between two lower clamp formworks Hinge axes it is vertical with the glide direction of upper die；Second driver is the both ends gas hinged with lower clamp formwork and rack respectively Cylinder；Die holder include the fixed block being connect with rack, two safe blocks being slidably connected on fixed block and locking fixed block with The locking piece of safe block relative position；The glide direction of safe block and the glide direction of upper die are vertical, and lower clamp formwork is separately connected In two safe blocks.

By using above-mentioned technical proposal, die holder is split into three parts, when fixed block is opposite with safe block to be slided, the When two drivers elongation driving lower clamp formwork, lower clamp formwork will drive safe block sliding, will not form effective clamping；Only fixed block When relatively fixed with safe block, lower clamp formwork rotation just will form effective clamping；It only uses locking piece locked secure block and consolidates Determine the relative position of block, equipment could work normally, and locking piece and safe block are set to insure together.Because of the position of die holder The operating space set apart from operator's both hands is nearest, and locking piece is always positioned at operator within sweep of the eye in operating process, lock A possibility that determining part and pedal while accidentally being touched is very low, because maloperation accordingly reduces a possibility that leading to operator's clamp hand, Operator uses safer.

Preferably, being provided with sliding slot on fixed block, safe block is equipped with sliding block compatible with the sliding slot, and sliding block is in sliding slot Interior sliding.

The opposite shifting of fixed block and safe block is realized using the structure of sliding slot and sliding block by using above-mentioned technical proposal Dynamic, movement routine is relatively fixed, convenient for resetting, convenient for the use of operator.

By using above-mentioned technical proposal, the form in hole is entered using bar, utilizes the lock also cross fixed block and safe block Fixed pole fixes the two relative position, and structure is simple, locks and contact locking.

Preferably, being connected with retention bead in sliding slot；When retention bead is abutted with sliding block, first positioning hole is fixed with second The alignment of position hole.

By using above-mentioned technical proposal, with cooperation slide block structure cooperation, abutted using retention bead with sliding block, it is this can With the index of direct feel in operation, as the foundation for judging whether first positioning hole and second location hole are aligned, behaviour Make simple, accuracy height, the efficiently and accurately of user operates.

Preferably, being connected with the elastic parts affixed with sliding block in sliding slot, the elastic parts is applied to sliding block towards limit The power of position protrusion.

By using above-mentioned technical proposal, elastic parts, which is arranged, can be driven after safe block is detached from original position using elastic force Dynamic safe block is kept in the center, it is possible to reduce the labour of operator, equipment operation are more easy.

Preferably, locking piece further includes the sliding bar affixed with locking level, fixed block is equipped with compatible with sliding bar Slide opening.

The shifting of locking level can be accurately controlled using the cooperation of sliding bar and slide opening by using above-mentioned technical proposal Dynamic direction, is accurately inserted into first positioning hole and second location hole convenient for locking level, is further simplified the operation of operator.

Preferably, projection of the locking level in the plane perpendicular to sliding bar glide direction, has part to fall in slide opening in institute It states except the range projected in plane.

By using above-mentioned technical proposal, make locking level that can not pass through slide opening, it can be direct with fixed block to avoid locking piece Separation, helps avoid the case where locking piece falls, loses appearance.

Preferably, locking piece further includes connecting rod affixed with two sliding bars respectively.

By using above-mentioned technical proposal, two locking levels are connected, operator can be made same using once-through operation When complete two safe blocks locking, can simplify the operation of operator.

Preferably, being bent camber to away from the direction of upper pressure component in the middle part of connecting rod.

By using above-mentioned technical proposal, connecting rod can be made to be relatively distant from pressure component, and then by the operation of operator Position is moved to presses on the position of component relatively far away from apart from upper, can reduce the probability that operator directly touches pressure component, Help to improve the safety coefficient of equipment.

Preferably, the edge of connecting rod is rounded structure.

By using above-mentioned technical proposal, the sharp corners on the position that operator can touch are got rid of, help to protect Operator is protected, while helping to improve operating handle.

In conclusion the utility model has the following beneficial effects:

A possibility that increasing by one of safety structure, reducing operator's clamp hand, the safety coefficient of equipment is higher；It is easy to operate, Convenient for the use of operator；Operating handle is good.
