The second worktable 5 is located on the right side of the top of the first worktable 4 through a lifting device 20.

An automatic lubrication device 25 is located inside the frame 1. An operation panel 27 is connected to the top left front side of the frame 1 via a rocker arm 26.

[0032] The blown bottle produced by this invention features a four-layer structure, including an adhesive layer, an inner layer, an EVOH layer, and a main layer.

The lifting structure allows the first worktable 4 and its upper components to move and adjust vertically to adapt to the melting temperature and flowability of different plastic materials, optimizing the extrusion process and achieving precise control over multi-layer material composites.

[0033] Example 2

[0034] like Figures 1 to 5 The illustrated fully electric four-layer preservation bottle blowing machine includes a frame 1, which is specifically composed of an aluminum alloy frame. Both sides of the frame 1 are equipped with baffles 2, which are hinged to the outside of the frame 1 to prevent external dust from entering the frame 1 and affecting the preparation of the preservation bottles. A first worktable 4 is slidably arranged on the bottom right side of the frame 1 through a lifting mechanism 3. A second worktable 5 is arranged on the top right side of the first worktable 4 through a lifting device 20. Four rubber extruders 6 are arranged on the top of the second worktable 5.

[0035] The first worktable 4 can move up and down the lifting device 20, the second worktable 5, and multiple rubber extruders 6 under the action of the lifting mechanism 3 to adapt to different production needs. It is known that different plastic materials have different melting temperatures and fluidity. By adjusting the height of the rubber extruders 6, the extrusion process of the rubber material can be further optimized, including changing key parameters such as material pressure, flow rate, and temperature during the extrusion process, to ensure that each material can achieve the best molding effect during the blow molding process, and ultimately enable each preservation bottle to achieve the most ideal molding effect.

[0036] The second worktable 5 can be lifted upward by the lifting device 20, which is mainly suitable for lifting the extruders 6 upward after the hot cutter cuts the tubular rubber material injected into the die head. This prevents the tubular rubber material at the tube opening of the extruder 6 from sticking to the tubular rubber material at the die head again, which would be detrimental to the forming of the tubular rubber material in the die head.

[0037] Furthermore, multiple rubber extruders 6 can be installed on the top of the second workbench 5. The specific number can be set according to the required number of layers of the preservation bottle. In this embodiment, which is mainly for the blow molding of 4-layer preservation bottles, 4 rubber extruders 6 are set up to extrude the adhesive layer, inner layer, EVOH layer and main layer respectively, so as to finally realize the blow molding of 4-layer preservation bottles.

[0038] Specifically, a support frame 7 is provided extending to the left from the top of the second worktable 5. A first extruder 601 for extruding the adhesive layer is installed on the left side of the support frame 7. A second extruder 602 for extruding the inner layer is provided on the front side of the top of the second worktable 5. A third extruder 603 for extruding EVOH is provided on the rear side of the top of the second worktable 5. A fourth extruder 604 for extruding the main layer is provided on the right side of the top of the second worktable 5.

[0039] Understandably, the final blown glass bottle consists of, from the inside out, an inner layer, an EVOH layer, an adhesive layer, and a main layer. The inner layer is the part of the bottle that directly contacts the food or beverage it contains, therefore requiring good sealing and transparency. It is typically made of non-toxic, odorless materials that meet food safety standards, such as vinyl alcohol (PVA) or polyethylene vinyl acetate (EVA). Its main function is to maintain the temperature of the contents, prevent leakage, and ensure the quality and safety of the food or beverage. EVOH, specifically an ethylene / vinyl alcohol copolymer, has good gas barrier properties, effectively preventing the penetration of gases such as oxygen and carbon dioxide, thus extending the storage time of food. It is mainly used to improve the preservation performance of the bottle. The main layer is the outermost layer of the bottle, primarily enhancing its structural strength and durability, protecting the inner and EVOH layers from environmental damage such as ultraviolet radiation and impacts. The adhesive layer, located between the EVOH layer and the main layer, increases the adhesion and bonding strength between the EVOH layer and the main layer materials.

[0040] The extruder 6 is mainly used to heat and compress plastic material into molten plastic material. Specifically, the second worktable 5 is equipped with a support base 15 on top. A motor 16 is installed on the right side or above the support base 15. Feed pipes 18 are connected to the support base 15 at the position opposite to the motor 16. Feed hoppers 17 are provided on the top or right side of the feed pipes 18. Plastic material is put into different feed hoppers 17. Then, the motor 16 drives the screw in the feed pipe 18 to rotate, which drives the plastic material to move in the feed pipe 18 along the force of the screw. During this process, the plastic material is heated and melted by the heating plate in the feed pipe 18. Finally, it flows to the double die head 9 on the left side of the support frame 7.

[0041] Example 3

[0042] like Figures 1 to 5 The illustrated fully electric four-layer food preservation bottle blowing machine has nozzle mechanisms 8 installed on both the front and rear sides of the upper part of the support frame 7. A double-die head 9 for stretching is connected to the left side of the support frame 7. The double-die head 9 has multiple flow channels. In this embodiment, the double-die head 9 has at least 4 flow channels, which are respectively connected to the feed pipes 18 of 4 rubber extruders 6. When 4 different plastic materials are plasticized into molten rubber by the rubber extruders 6, they can be technically fused after flowing into the 4 flow channels to form a 4-layer tubular semi-transparent rubber material that flows into the mold to facilitate the production of the four-layer food preservation bottle.

[0043] The nozzle mechanism 8 is located on both the front and rear sides of the double mold head 9. The nozzle mechanism 8 includes a blower servo motor 16 and a blower assembly driven by the blower servo motor 16. The blower servo motor 16 transmits power to the blower assembly through a gear and rack mechanism or a screw transmission mechanism to drive the blower assembly. After the blower assembly is started, it is inserted downward into the mold and compressed air is introduced at the same time to make the tubular semi-transparent rubber material in the mold quickly form into a preservation bottle and cool it during the shaping process.

[0044] The aforementioned mold is specifically installed on the mold clamping frame assembly 11, which is located inside the frame 1 and is mainly driven by the symmetrically arranged mold moving arm assembly 10. The mold clamping frame assembly 11 is divided into a front mold clamping frame 111 and a rear mold clamping frame 112, which are used to install the front mold and the rear mold, respectively. The front mold and the rear mold move inward simultaneously until they are in close contact, forming a bottle cavity for blowing after the tubular semi-transparent rubber material is put in. Understandably, the front mold clamping frame 111 and the rear mold clamping frame 112 are symmetrically arranged below the double-die head 9 for pulling rubber, so that the double-die head 9 can directly flow the four layers of tubular semi-transparent rubber material into the mold for blowing, shaping, cooling and other steps.

[0045] Furthermore, the mold-moving swing arm assembly 10 is specifically driven by the motor 16 to move the mold. That is, the swing arm is connected to the front mold-locking frame 111 and the rear mold-locking frame 112 respectively. In order to avoid the front mold-locking frame 111 and the rear mold-locking frame 112 moving asynchronously, which would cause the top opening of the mold to fail to align with the glue-pulling double mold head 9, a synchronization structure 19 is also connected between the mold-locking frame assembly 11 and the mold-moving swing arm assembly 10. This is used to realize the synchronous drive of the motor 16, so that the front mold-locking frame 111 and the rear mold-locking frame 112 move in the same direction, at the same speed and in the same distance, to ensure precise mold locking.

[0046] A hot cutting device 14 is located on the bottom left side of the frame 1. The hot cutting device 14 is located on the right side of the mold and is driven by a motor 16 to move up and down. It can be understood that the hot cutting device 14 is initially located on the left side of the mold head. When a certain volume of tubular rubber material is placed in the mold, the hot cutting device 14 is activated to cut off the tubular rubber material at the mold opening. At the same time, the lifting device 20 is activated to drive the rubber extruder 6 and the rubber pulling double mold head 9 to lift upwards to prevent the tubular rubber material from sticking to the tubular rubber material at the mold opening. At the same time, the hot cutting device 14 retracts. Considering that there may be some residue after the hot cutting device 14 cuts off the rubber material, if it is not cleaned, it will affect the next cut. Therefore, after one hot cut, the hot cutting device 14 will move down to the cooling water device 24 near the bottom of the cabinet to cool and remove the residual tubular rubber material, which is convenient for the next hot cutting operation.

[0047] Example 4

[0048] like Figures 1 to 5 The illustrated fully electric four-layer fresh-keeping bottle blowing machine has an upper water nozzle device 12 located on the upper left side of the frame 1 and a lower water nozzle device 13 located on the lower left side of the frame 1. Both water nozzle devices are located outside the mold clamping frame assembly 11 and are mainly used to remove the edge scraps of the bottle body after cooling, completing the final production of the bottle. The water nozzle device specifically includes a cutter and a shear. The system inputs the actual data of the bottle body and inputs it into the corresponding control system. The control system controls the movement of the cutter and shear according to the predetermined trajectory of the bottle body to ensure accurate shearing position and shearing process.

[0049] Furthermore, collection chambers 21 are symmetrically arranged on the front and rear sides of the left side of the frame 1. A robotic arm 22 is installed in the collection chamber 21 to catch the bottle residue generated by the water dispensing device, and then slide out through the collection trough 23 located on the left side of the frame 1 below the robotic arm 22 to complete the collection of the bottle residue.

[0050] Example 5

[0051] Furthermore, a cooling water device 24 is provided on the bottom left side of the frame 1. It mainly introduces cooling water to special parts of the machine, such as molds, through water supply pipes and a cooling water circulation system to provide cooling and temperature reduction, so as to keep them within the normal operating temperature range and ensure the stability and quality of the molding process. The frame 1 is also equipped with an automatic lubrication device 2516, which is mainly used to provide precise and continuous lubrication and maintenance for key parts of the machine. Through a tightly arranged lubrication oil pipeline, lubricating oil that meets specific requirements is accurately introduced into each key part of the machine, reducing the friction and wear generated by each device during operation, thereby significantly improving the overall operating efficiency of the machine and greatly extending the service life and maintenance cycle of each device.

[0052] Furthermore, an operation screen 27 is connected to the top left front side of the frame 1 via a rocker arm 26. Specifically, it is a touch screen connected to the rocker arm 26. The operation screen 27 connected via the rocker arm can be adjusted by the user to change the screen orientation to meet the needs of different personnel. The touch screen can display the operating status and data of the blow molding machine in real time, easily monitor the operating status and parameters of bottle blowing, and the operator can also directly input various commands and view data through the touch screen. After receiving the operator's commands, the touch screen transmits the commands to the production equipment to realize the automated control of the production equipment and improve the automation level of the production line. A second electrical control box 2928 is located on the right front side inside the frame 1, which is used to provide electrical automatic control for the entire machine, including but not limited to pneumatic devices that can provide compressed air and heat dissipation air sources for all pneumatically driven mechanisms inside the machine. A second electrical control box is located on the right rear side inside the frame 1, which is mainly used to realize the automated electrical control of the drive.

[0053] Example 6

[0054] like Figures 1 to 5 The illustrated fully electric four-layer bottle blowing machine for preservation has a staircase 31 on the top front right side of the frame 1, which is used by operators to enter the working area of ​​the frame 1 for observation. The design and installation of the staircase 31 allows operators to easily go up and down the staircase 31 to enter the frame 1 for observation and maintenance. A guardrail 30 is provided on the top right side of the frame 1 to protect the safety of operators after entering the working area of ​​the frame 1. The design and installation of the guardrail 30 effectively isolates and protects the space above the frame 1, preventing personnel from accidentally entering or causing accidents.
