The improved heat sealing machine of a kind of work top
Technical field
The utility model relates to a kind of heat sealing machine, specifically is the improved heat sealing machine of a kind of work top.
Background technology
Heat sealing machine is widely used in various different industries; Its major function is to utilize high-frequency electric field or high temperature to make plastics or a class plastics inner molecular oscillation produce heat energy and carry out the bonding processing that each based article merges, and therefore is the preferred unit of the heat seal side cut of plasthetics or type plasthetics.
At present, existing heat sealing machine comprises frame, is located at welding mechanism and work top on the frame, welding mechanism comprise by driving mechanism drive can on move the pushed pressing plate directly over the work top that is positioned at that presses down; Work top can slide before and after on the slide rail of its both sides, during work, places processing work by a staff of a side; Opposite side need be equipped with another staff who matches, though the operating efficiency of this heat sealing machine is higher, an equipment needs two operating personnel; Obviously also impracticable; In addition, in case two operating personnel do not work good, be easy to make another operating personnel to damage.
The utility model content
The utility model provides a kind of work top improved heat sealing machine, has problems such as above-mentioned deficiency to solve existing heat sealing machine.
The utility model adopts following technical scheme:
The improved heat sealing machine of a kind of work top comprises fixed support, is located at work top and welding mechanism on the fixed support, said welding mechanism comprise air cylinder driven mechanism and drive can on move the pushed pressing plate directly over the work top that is positioned at that presses down.
As the improvement of the utility model, first workbench and second workbench that said work top comprises upper and lower slide rail and is located at upper and lower slide rail respectively and can alternately slides above that.
Said first workbench and the second workbench rear side are respectively equipped with its front and back of driving that are fixed on the said fixed support and replace first cylinder and second cylinder that slides.
Said pushed pressing plate, first workbench and the second workbench inside are equipped with heat generating components.
As a kind of preferred version of the utility model, the rear wall of said upper and lower slide rail all with the concordant setting of the rear wall of said pushed pressing plate.
As the another kind of preferred version of the utility model, said air cylinder driven mechanism comprises a piston rod, and this piston-rod lower end portion is socketed with backing plate, and lower end is connected with said pushed pressing plate, the flexible member that is provided with between said backing plate and the pushed pressing plate.
Can know by above-mentioned description, compare the utility model tool with prior art the utility model structure
Following advantage is arranged: first workbench that this heat sealing machine is provided with and second workbench can alternately place the pushed pressing plate under in order to workpiece is carried out the welding moulding; Therefore only need operating personnel to carry out welding work; Saved human and material resources; Its production efficiency is efficient, because this equipment is higher by its safety coefficient of people's control operation.

Fig. 2 is the front view of the utility model.
The specific embodiment
The specific embodiment of the utility model is described with reference to the accompanying drawings.
The improved heat sealing machine of a kind of work top; See figures.1.and.2; Comprise fixed support 1, be located at work top 2 and welding mechanism 3 on the fixed support 1; Said welding mechanism 3 comprise air cylinder driven mechanism 31 and drive can on move the pushed pressing plate 32 directly over the work top 2 that is positioned at that presses down; First workbench 23 and second workbench 24 that work top 2 comprises upper and lower slide rail 21,22 and is located at upper and lower slide rail 21,22 respectively and can alternately slides above that, said pushed pressing plate 32, first workbench 23 and second workbench, 24 inside are equipped with the heat generating components (not shown).
With reference to Fig. 1; As a kind of preferred version; First workbench 23 and second workbench, 24 rear sides are respectively equipped with first cylinder 25 and second cylinder 26 that the driving that is fixed on the said fixed support 1 is alternately slided before and after it, the rear wall of upper and lower slide rail 21,22 all with the concordant setting of the rear wall of said pushed pressing plate 32.
With reference to Fig. 2; As another kind of preferred version, said air cylinder driven mechanism 31 comprises a piston rod 33, and this piston-rod lower end portion is socketed with backing plate 34; Lower end is connected with said pushed pressing plate 32, has been provided with the flexible member 35 of cushioning effect between said backing plate 34 and the pushed pressing plate 32.
During work; First workbench 23 and second workbench 24 alternately place pushed pressing plate 32 under; Pushed pressing plate 32 alternately compresses first workbench 23 and second workbench 24 is realized the welding to workpiece; This device just one operating personnel have saved human and material resources, and its production efficiency is efficient and safety coefficient is higher.
The above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
