The frame 1 is driven and connected to the support plate 2 via a lifting device 15. The electric mold mechanism 14 includes a mold transfer frame 16 and a sprue cutting device 17, both of which are symmetrically arranged. The mold is fixedly mounted on the mold transfer frame 16. A nozzle mechanism 19 is movably mounted on the frame 1 via a moving mechanism 18.

An electrical control box 22 is fixedly mounted on the frame 1, and an operation panel 24 is fixedly mounted on the frame 1 via a rocker arm structure 23.

[0022] Through the above technical solution, this utility model has a five-layer adhesive-pulling single extruder head 4 fixedly installed on the support plate 2. A transparent layer extruder 5 is fixedly installed on the five-layer adhesive-pulling single extruder head 4. An inner layer extruder 6, an adhesive layer extruder 7, a main feed extruder 8, and an EVOH layer extruder 9 are fixedly installed on the support plate 2. The inner layer extruder 6 is connected to the five-layer adhesive-pulling single extruder head 4 through an inner layer conveying pipe 10. The adhesive layer extruder 7 is connected to the five-layer adhesive-pulling single extruder head 4 through an adhesive layer conveying pipe 11. The main feed extruder 8 is connected to the main feed conveyor... Pipe 12 is connected to the five-layer extrusion head 4. The EVOH layer extruder 9 is connected to the five-layer extrusion head 4 through the EVOH layer conveying pipe 13.

When producing stacking barrels, according to the purpose of the stacking barrels, blow molding material for that purpose is added to the inner layer extruder 6 and the main feed extruder 8. The controller intelligently controls the extruders to extrude stacking barrels with composite layers according to the set stacking barrel production parameters, thereby improving the quality of the stacking barrels.

[0023] Example 2:

[0024] like Figures 1-6 As shown, this invention aims to improve the quality of stackable drums through multi-layer co-extrusion blow molding technology. This equipment produces stackable drums with composite structures by precisely controlling the extrusion and molding of different materials to meet the storage and transportation needs of various liquid materials. The core of this invention is a five-layer extrusion extruder 4, which can simultaneously process five different materials, including a transparent layer, an inner layer, an adhesive layer, a main feed layer, and an EVOH layer. The transparent layer extruder 5 is responsible for producing the outer surface of the drum, providing transparency and appearance. The inner layer extruder 6 is responsible for producing the inner surface of the drum; this layer is in direct contact with the stored liquid material, so the choice of its material is crucial to the safety and durability of the drum. The adhesive layer extruder 7 ensures a tight bond between the layers, enhancing the overall strength of the drum. The main feed extruder 8 is responsible for producing the main body of the drum, a key component of the drum structure and the main supporting material layer for the stackable drum. The EVOH layer extruder 9 is responsible for producing a high-barrier ethylene-vinyl alcohol copolymer layer, which can significantly improve the barrier properties of the barrel against gases and liquids, making it particularly suitable for storing chemical materials that require high barrier properties.

[0025] Each layer of material is connected to the five-layer extrusion head 4 via a dedicated conveying pipe, ensuring precise and uniform extrusion and molding. The design of the inner layer conveying pipe 10, adhesive layer conveying pipe 11, main feed conveying pipe 12, and EVOH layer conveying pipe 13 guarantees the continuity and uniformity of material extrusion, avoiding material waste and instability during production. The control system of the intelligent blow molding machine is the soul of the entire equipment. It intelligently controls the working status of each extruder according to preset production parameters, including extrusion speed, temperature, and pressure, ensuring the uniformity and stability of the composite layer structure of the barrel. The controller monitors various parameters in real time during production through sensors and automatically adjusts the working status of the extruders to adapt to different production needs and material characteristics. The electric mold mechanism 14 is an important component of the blow molding machine. It is responsible for clamping and fixing the blow molding mold, ensuring the molding accuracy of the barrel during the blow molding process. The design of the electric mold mechanism 14 improves the convenience of operation and the speed of mold change, increasing production efficiency and equipment flexibility. The electrically driven mold mechanism provides a stable clamping force, ensuring that the mold does not shift due to pressure changes during blow molding, thus guaranteeing the molding quality of the barrel. During production, appropriate blow molding materials are added to the inner extruder 6 and the main feed extruder 8 according to the intended use of the stacked barrels and the characteristics of the stored materials. For example, for storing chemicals requiring high corrosion resistance, materials such as high-density polyethylene or polypropylene can be added. For materials requiring high barrier properties, such as certain chemicals or food ingredients, the choice of material for the EVOH layer is particularly important.

[0026] The support plate 2 and safety door 3 fixedly installed on the frame 1 provide a safe working environment for operators. The design of the safety door 3 prevents accidents during production and protects the safety of operators. At the same time, the safety door 3 also facilitates equipment maintenance and repair. Furthermore, this invention is energy-saving and environmentally friendly. By precisely controlling the working state of the extruder and the blow molding process, energy consumption and material waste are reduced. The energy-saving design of the equipment meets the requirements of modern industrial production for environmental protection and sustainable development. This invention, through multi-layer co-extrusion blow molding technology, produces high-quality stacking drums with composite structures, meeting the storage and transportation needs of different liquid materials.

[0027] The frame 1 of this invention is designed with a lifting device 15, which drives the vertical movement of the support plate 2. The lifting device 15 is connected to the support plate 2 via a precise drive system, allowing the five-layer extrusion head 4, inner layer extruder 6, adhesive layer extruder 7, main feed extruder 8, and EVOH layer extruder 9 on the support plate 2 to rise or fall as a whole. This action is crucial for the entire blow molding process because it allows the five-layer extrusion head 4 to work closely with the electric mold mechanism 14 during production. During the blow molding of the stacked barrels, the five-layer extrusion head 4 needs to precisely align with the mold on the electric mold mechanism 14 to ensure uniform barrel molding. After molding, the lifting device 15 drives the support plate 2 to rise, raising the five-layer extrusion head 4 and providing operating space for subsequent sprue cutting and barrel demolding. This step is part of an automated production process designed to improve production efficiency and reduce manual intervention. The head-up device 15 is designed with operational smoothness and precision in mind, ensuring the extruder and the single-head extruder remain stable during lifting and lowering, preventing mechanical vibration or displacement from affecting equipment operation. Furthermore, the head-up device 15 is equipped with safety limit switches and emergency stop functions to prevent accidents during operation and ensure the safety of the equipment and operators.

[0028] The electric mold mechanism 14 of this utility model includes a mold transfer frame 16 and a sprue cutting device 17. The mold transfer frame 16 moves the mold from the forming position to the demolding position after the stacked barrel is blow-molded, while the sprue cutting device 17 cuts off the blow molding sprue of the stacked barrel to separate the finished stacked barrel from excess material. The design of the mold transfer frame 16 allows the mold to move quickly and accurately during the blow molding process, which not only improves production efficiency but also reduces wear on the mold and equipment. The sprue cutting device 17 ensures rapid and clean cutting of the sprue. Both the mold transfer frame 16 and the sprue cutting device 17 are symmetrically arranged, improving production efficiency. During production, the mold transfer frame 16 moves the mold to below the five-layer single-head blow molding machine 4 for blow molding. Once the stacked barrel is formed, the mold transfer frame 16 moves the mold back to the demolding position, at which point the sprue cutting device 17 intervenes to cut off the sprue. This alternating movement and cutting process allows the blow molding machine to perform blow molding on one mold while another is demolding, achieving continuous production. With this setup, the fully electric stacking barrel intelligent blow molding machine can reduce idle time during production while ensuring product quality, enabling the equipment to run continuously, thereby improving overall production capacity and significantly increasing production efficiency.

[0029] The frame 1 of this invention is movably mounted with a nozzle mechanism 19 via a moving mechanism 18. This design is for cooling the stacked barrels after blow molding. The main function of the nozzle mechanism 19 is to blow low-temperature gas onto the demolded stacked barrels. This process rapidly reduces the temperature of the barrel, allowing it to cool and set quickly. This rapid cooling is crucial for improving production efficiency and ensuring product quality. The design of the nozzle mechanism 19 ensures the uniformity and efficiency of the cooling process. By precisely controlling the temperature and flow rate of the blown gas, the nozzle mechanism 19 can uniformly cool all parts of the barrel, preventing product deformation or uneven strength caused by uneven cooling. Furthermore, the rapid cooling capability of the nozzle mechanism 19 also reduces the waiting time required for the barrels after demolding, thereby accelerating the entire production process. In actual operation, the cooling effect of the nozzle mechanism 19 directly affects the production cycle of the stacked barrels. By reducing cooling time, the nozzle mechanism 19 helps increase the throughput of the production line, allowing more stacked barrels to be produced in the same amount of time.

[0030] The frame 1 of this invention is fixedly equipped with a staircase 20. This design facilitates the safe and convenient addition of production materials to the extruder by operators. The staircase 20 provides a stable passage, allowing operators to easily reach the top of the equipment for material addition or maintenance. A guardrail 21 is fixedly installed around the perimeter of the support plate 2, serving as an important safety measure. The guardrail 21 protects operators during operation, preventing accidental falls or other accidents. The guardrail 21 has a robust and reliable structural design, maintaining stability under various working conditions and providing continuous safety even during high-intensity blow molding operations. The combined use of the staircase 20 and guardrail 21 not only improves work efficiency but also enhances operational safety.

[0031] An electrical control box 22 is fixedly installed on the frame 1 of this utility model. This control box 22 is specifically designed to centrally house the control circuitry. The control circuitry is the nerve center of the blow molding machine, responsible for receiving operating commands and coordinating the operation of various parts of the machine. The placement of the control box 22 ensures the safety and ease of maintenance of the control circuitry. Its sealed design prevents dust and moisture from entering, protecting the internal circuitry from damage and ensuring stable long-term operation of the machine. An operation screen 24 is fixedly installed on the frame 1 via a rocker arm structure 23. This design allows the operation screen 24 to be flexibly adjusted in position and angle according to the operator's needs. The rocker arm structure 23 allows the operation screen 24 to move within a certain range, ensuring that the operator can clearly see the screen content and perform operations from different positions. The operation screen 24 is a human-machine interface, through which the operator can monitor the production process, adjust production parameters, and start or stop the production process. The operation screen 24 is equipped with an intuitive user interface that displays production status, parameter settings, and fault diagnosis information, enabling the operator to quickly grasp the machine's operating status and take corresponding actions.
