The inner plate 604 is internally provided with a temperature control plate 605, the temperature control plate 605 is connected with a control system, and the temperature of the air is adjusted by the temperature control plate 605.
The working principle of the application is as follows:
the upper die 3 is pushed downwards by the demoulding cylinder 4, so that the upper die 3 and the lower die 2 are clamped, and the lower die 2 and the upper die 3 are matched with each other to form a forming cavity. After the upper die 3 and the lower die 2 are combined, the cylinder is driven to push the auxiliary air ring 612 towards the direction of the shaft sleeve 8, so that the outer cylinder 610 is inserted into the upper die 3 and the lower die 2 and positioned outside the shaft sleeve 8, the auxiliary air ring 612 is connected with an air supply system, and the air supply system infuses air into the outer lining 611 through the auxiliary air ring 612, so that the outer lining 611 expands and extrudes the inner lining 9, and the sealing performance between the outer lining 611 and the inner lining 9 is improved, and hot air is prevented from leaking from the forming cavity. The outer liner 611 fills the sealing groove after expansion for further enhancing the sealing performance between the outer liner 611 and the inner liner 9.
The composite layer 5 is continuously fed into the feed chute, the air supply system is used for exhausting air, so that the guide pipe 606 starts to extract air in the working cavity, the inner plate 604 cannot extract the air in the forming cavity through the air passage due to the limitation of the negative pressure spring, and the air in the pressure release cavity starts to generate acting force on the T-shaped end of the inner plate 604 along with the reduction of the pressure in the working cavity, and the inner plate 604 is pushed outwards, so that the distance between the inner plate 604 and the inner wall of the forming cavity is reduced, and the inner plate 604 is convenient for adsorbing the composite layer 5; when the difference between the air pressure in the working cavity and the external air pressure is larger than the tension of the negative pressure spring on the negative pressure plate 607, the air in the air passage starts to enter the working cavity, the inner plate 604 starts to extract the air in the forming cavity, and the negative pressure is utilized to adsorb the composite layer 5;
the inner plate 604 with the material plate is in a vertical state and is positioned below, the front end of the composite layer 5 is intercepted by the L-shaped end of the material plate, the material plate adsorbs the composite layer 5 through an adsorption port, when an external air supply system detects pressure value change, a driving motor drives a driving shaft 6 to rotate, and other inner plates 604 adsorb the composite layer 5 sequentially under the driving of the driving shaft 6.
According to the length of the composite layer fed into the feed chute, the control system controls the hydraulic cylinder to work, the cutter 201 stretches out of the breaking chute under the control of the hydraulic cylinder, cuts off the composite layer 5 in the feed chute, and after the cut-off composite layer 5 completely enters the forming cavity, the driving shaft 6 pulls the composite layer 5 through the composite pulling plate 602, and bends the composite layer into a cylindrical structure in the forming cavity, so that the composite layer 5 can form a complete inner bag blank in the forming cavity.
The subsequently input composite layer 5 continues to advance a certain distance into the feed chute, the subsequently input composite layer 5 continues to enter the feed chute and is stained with lubricating oil, after being stained with the lubricating oil, the cut composite layer 5 can be pulled back in the original way, and the stained lubricating oil is smeared on the surface of the feed chute.
When the cut composite layer 5 completely enters the forming cavity and the subsequently input composite layer 5 is extracted from the feeding groove, the sealing plate 203 seals the feeding groove under the pushing of the closing cylinder 202 and is matched with the lower die 2 to form a complete die cavity without an opening, so that the subsequent hot press forming of the composite layer 5 in the forming cavity is facilitated. When the feed chute is plugged by the sealing plate 203, the oil port 204 is plugged by the sealing plate 203, and meanwhile, all lubricating oil stored before enters the forming cavity.
After the closing plate 203 seals the feed chute, the air supply system infuses air into the driving shaft 6, the guide pipe 606 guides air into the working cavity, the pressure value in the working cavity is unbalanced with the pressure value in the air passage, the negative pressure plate 607 is reset under the pulling of the negative pressure spring, and meanwhile, the negative pressure value in the air passage pulls out the positive pressure plate from the positive pressure port, so that the air in the working cavity enters the air passage, the air passage loses negative pressure, the composite layer 5 is released, the inner plate 604 releases the adsorption to the composite layer 5 along with the inner plate 604, and the air in the working cavity enters, and when the pressure value in the working cavity is equal to the pressure value in the pressure release cavity, the inner plate 604 withdraws the plate sleeve 603 and is far away from the composite layer 5. And as the air pressure in the working chamber increases continuously, air in the working chamber enters the air passage through the positive pressure port and flows into the forming cavity through the inner plate 604, so that the air pressure in the forming cavity increases and reaches the pressure value of the hot pressing process.
When the temperature control plate 605 adjusts the air temperature through the peltier effect and needs hot press treatment, the temperature control plate 605 heats the air under the control of the control system, so that the hot air is ejected from the inner plate 604, and the hot press molding of the inner bag is completed.
When hot air is infused into the forming cavity, the driving shaft 6 rotates under the driving of the driving motor, and through the cooperation of the inner plate 604 and the plate sleeve 603, the stirring of air in the forming cavity is realized, the hot air is driven to flow, a low-temperature area is not formed between the composite layer 5 and the hot air due to heat exchange, and the forming efficiency of the inner bag is further improved.
After the composite inner bag is formed by hot pressing, the demolding cylinder 4 pulls the upper die 3 to ascend, and then the driving shaft 6 also moves upwards under the lifting of the lifting cylinder 104, so that the formed composite inner bag is separated from the upper die 3 and the lower die 2. The formed inner bag can be subjected to a subsequent welding process to form a complete inner bag.
