Description

Technical Field

[0001] This invention relates to the field of pressure blowing technology, and specifically to an energy-saving pressure blowing machine for glass bottles. Background Technology

[0002] Press-blown glass is an important production process for manufacturing bottled glass products such as glass bottles. Its core feature is that the bottle mouth and basic shape are first formed by pressing with a mechanical punch, and then the final shape is formed by blowing with compressed air. It can be divided into two steps. In the first step, after the molten glass droplet enters the initial mold, the bottle mouth and basic shape of the bottle body are formed in one go by the mechanical pressure of the metal punch. The accuracy of the bottle mouth is precisely controlled by the die. In the second step, the die carries the basic shape of the glass bottle to the forming mold, where it is blown with high-pressure air to make the glass completely fit the inner wall of the mold, forming the final size and shape.

[0003] The existing patent application with application number CN202021180236.5 discloses a four-drop quick-change pressure blowing mechanism. A centering ring is added to the upper part of the cylinder and connected to the bottle opening device through the centering ring. A transition plate is provided at the bottom of the drive cylinder and connected to the base through the transition plate. The centering ring, the cylinder and the drive cylinder are vertically connected in series by a connecting device and connected to the base through the connecting device. The transition plate and the base are provided with multiple connection holes, and the air passage and lubrication pipeline are connected to the lower part of the drive cylinder through the multiple connection holes.

[0004] In the press blow molding process, the formation of the bottle neck is crucial. The bottle neck must be round and the threads must be clear. Unlike the bottle body, the bottle neck is formed more by pressing. If there is a large temperature difference between the bottom mold and the mouth mold, it is easy to cause the bottle neck to be out of round or the threads to be defective. These defects cannot be remedied by subsequent blowing. The original temperature control system can only cool the bottle uniformly, and it is difficult to control the local temperature. Once defects occur, all glass bottles in the same batch will be defective. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an energy-saving glass bottle press blow molding machine, which can effectively solve the problem of how to increase the yield of bottle mouths in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an energy-saving glass bottle press blow molding machine, comprising a primary mold, a forming mold, a punch, a nozzle mold, and a bottom mold, and further comprising: The temperature measurement and cooling components are symmetrically distributed on both sides of the upper part of the bottom mold and can slide to the top of the bottom mold to provide liquid cooling. The air-cooling kit, symmetrically distributed on both sides of the bottom mold, can slide to the top of the bottom mold to provide air cooling. It includes an air outlet pipe that extends obliquely between the die and the temperature measuring and cooling component, providing a fixed temperature and intermittent airflow.

[0007] Furthermore, the temperature measuring and cooling component includes several sets of symmetrically distributed arc mounting blocks, with the arc mounting blocks facing each other in pairs, and two arc mounting blocks combined to form a closed circumference. Multiple infrared temperature sensors and atomizing nozzle groups are embedded and fixedly installed on the arc mounting block. The infrared temperature sensors are used to detect the temperature at various locations inside the die, including the threaded positions. The atomizing nozzle groups are used to spray atomized droplets onto the local high temperature. The atomizing nozzle groups are symmetrically distributed in pairs above and below the infrared temperature sensors.

[0008] Furthermore, the air-cooling kit includes multiple sets of air-cooling sleeve one and air-cooling sleeve two of the same specifications. After the air-cooling sleeve one and air-cooling sleeve two are combined, they form a column shape. An air inlet pipe is fixedly connected through the upper side of the air-cooling sleeve one, and an air outlet pipe is fixedly connected through the lower side of the air-cooling sleeve two.

[0009] Furthermore, both the inner walls of the first and second air-cooled sleeves are fixedly equipped with spiral half-slices. After the first and second air-cooled sleeves are combined, the spiral half-slices of the first and second air-cooled sleeves together form a complete spiral flow guiding structure. The airflow entering from the inlet pipe can follow the spiral path of the two combined spiral half-slices, flow out from the outlet pipe below, and flow into the space between the temperature measuring and cooling component and the die.

[0010] Furthermore, a thick-walled heat storage pipe and a temperature control valve are fixedly connected to the outlet pipe, with the temperature control valve located near the end of the outlet pipe.

[0011] Furthermore, cylinders are fixedly connected to the sides of both the first and second air-cooled sleeves to control their positions. A winding wheel is installed in the middle of the air outlet pipe, and the air outlet pipe is wound around the winding wheel.

[0012] Furthermore, it also includes a hydraulic cylinder, two movable plates and two slide rails. The two movable plates slide between the two slide rails. Symmetrically distributed air-cooled sleeve one and air-cooled sleeve two are slidably inserted on the two movable plates respectively. The air inlet pipe is set between the movable plate and air-cooled sleeve one or air-cooled sleeve two. Two sets of electric push rods fixedly connected to the movable plates are installed on both sides of the initial mold for adjusting the position of the movable plates. The hydraulic cylinder is fixedly installed below the bottom mold to control the height of the bottom mold, so as to accommodate the moving plate, the air-cooling kit, and the temperature measurement and cooling components.

[0013] Furthermore, multiple arc-shaped mounting blocks are fixedly installed on both of the movable plates, and the port of the air outlet pipe is fixed and passes through the movable plate and extends between the arc-shaped mounting block and the die. The winding wheel is fixedly installed inside the movable plate.

[0014] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. Due to the presence of threads and other structural features at the bottle neck, its quality is significantly affected by temperature, and defects are often irreparable. This design utilizes a temperature-sensing and cooling component to precisely detect the internal temperature of the die. It then precisely sprays atomized droplets into locally high-temperature areas. Combined with a constant-temperature airflow provided by the air-cooling kit, this rapidly evaporates droplets on the inner wall of the die, shortening droplet residence time and preventing droplet residue. The constant-temperature airflow stably controls the cooling rate and heat transfer, preventing temperature fluctuations from affecting the liquid cooling effect. Combined with the die's own cooling system, this achieves uniform and rapid cooling of the die, ensuring even temperature distribution during bottle neck pressing. This effectively improves issues such as poor bottle neck roundness and abnormal thread condition caused by localized overheating of the die, guaranteeing the stability of the bottle neck pressing effect.

[0015] 2. When the air-cooling sleeve of the air-cooling kit is closed, it can cover the bottom mold's moving mechanism. The airflow flows downwards along the spiral guide structure, effectively removing heat from the bottom mold's moving mechanism, especially providing precise heat dissipation above the higher-temperature components. Combined with the bottom mold's own air cooling, this achieves rapid and efficient heat dissipation, ensuring stable operating temperature of the bottom mold. Simultaneously, the airflow heated by the bottom mold can pass between the inlet mold and the temperature measuring and cooling components, assisting in the evaporation of atomized droplets, accelerating cooling, and preventing droplets from accumulating at the threads on the inner wall of the inlet mold. This further ensures the cooling effect of the inlet mold and provides a stable temperature environment for glass bottle pressure blow molding.

[0016] 3. The air-cooling kit, through the cooperation of thick-walled heat storage pipes and temperature control valves, can stably output airflow at a fixed temperature, avoiding the impact of fluctuating cooling on the cooling effect. The temperature-measuring cooling component uses sensors to accurately measure the temperature, combined with solenoid valves to control the spray pattern of the atomizing nozzle group, to achieve precise local cooling. The entire cooling system, through the coordinated action of the moving plate, electric push rod, and hydraulic cylinder, can quickly move to the working position after a single glass bottle is made, and quickly return to its original position after cooling, without affecting subsequent press-blowing processes. At the same time, the shielding strip design can prevent contaminant splashing, ensuring the reliability of equipment operation and improving the overall pass rate and process stability of glass bottle making.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Reference Figures 1 to 8 Example: An energy-saving glass bottle blow molding machine includes a primary mold 1, a forming mold 2, a punch 3, a mouth mold 4 and a bottom mold 5, and also includes a hydraulic cylinder 6, two moving plates 7 and two slide rails 11; Temperature measuring and cooling components 9 are symmetrically distributed on both sides of the bottom mold 5 and can slide to the top of the bottom mold 5 to provide liquid cooling; air cooling components 8 are symmetrically distributed on both sides of the bottom mold 5 and can slide to the top of the bottom mold 5 to provide air cooling, including an air outlet pipe 803 that extends obliquely between the die 4 and the temperature measuring and cooling components 9 to provide a fixed temperature and intermittent airflow.

[0023] Both movable plates 7 slide between two slide rails 11. Symmetrically distributed air-cooled sleeves 801 and 807 are slidably inserted on the two movable plates 7 respectively. An air inlet pipe 808 is set between the movable plate 7 and the air-cooled sleeve 801 or the air-cooled sleeve 807. Two sets of electric push rods 10 fixedly connected to the movable plates 7 are installed on both sides of the initial mold 1. The two electric push rods 10 are driven by a synchronous controller to ensure that the moving speed and position error of the movable plate 7 does not exceed ±1mm, and to ensure the precise docking of the air-cooled half sleeve and the arc mounting block. The hydraulic cylinder 6 is fixedly installed below the bottom mold 5 to control the height of the bottom mold 5 to accommodate the movable plate 7, the air-cooled kit 8, and the temperature measuring and cooling component 9. Multiple arc mounting blocks 901 are fixedly installed on both movable plates 7, and the port of the air outlet pipe 803 is fixed and passes through the movable plate 7 and extends to the arc mounting block 901 and the die 4. The winding wheel 804 is fixedly installed inside the movable plate 7.

[0024] In the glass blow molding process, molten glass falls into the closed space formed by the initial mold 1, the mouth mold 4, and the bottom mold 5. Then, the punch 3 moves down and presses the glass to form a prototype glass bottle with a glass bottle mouth and a certain bottle body shape. Next, the mouth mold 4 holds the glass bottle mouth position and flips it onto the bottom mold 5. By blowing air, the molten glass is shaped into the shape of the glass bottle, and the manufacturing process is completed.

[0025] When glass bottle necks are pressed, their quality is affected by temperature due to their threaded structure. Furthermore, if defects appear in the bottle necks after pressing, there are no remedial measures. Therefore, the pressing effect of the bottle necks must be stable.

[0026] The bottom mold 5 pushes upward and the punch 3 presses downward, forming the glass bottle neck through pressing. During this process, the top mold 4 and bottom mold 5 are the main areas for forming the glass bottle neck. Localized overheating within the top mold 4 can lead to a deterioration in the roundness of the bottle neck and affect the thread state. After flipping the glass bottle prototype, the top mold 4 returns to the top of the forming mold 2. During this time, the temperature measuring and cooling component 9 cools the inside of the top mold 4 using atomized droplets, and the air-cooling kit 8 cools the moving parts of the bottom mold 5. The air outlet pipe 803 in the air-cooling kit 8 exhausts air between the temperature measuring and cooling component 9 and the top mold 4. 8. The airflow used to cool the bottom mold 5 is heated by the bottom mold 5. Under temperature control conditions, a fixed-temperature airflow is applied between the temperature measuring and cooling component 9 and the die 4. The atomized droplets sprayed by the temperature measuring and cooling component 9 help evaporate the droplets sprayed on the die 4, avoid droplets, shorten the time the droplets stay in the die 4, and fix the temperature, that is, fix the speed at which the droplets are carried away and the heat transferred to the droplets. The fluctuating temperature changes will not affect the liquid cooling effect on the die 4. In this way, the heat that can be carried away by the combination of the sprayed droplets and the airflow can be controlled, which is a controllable cooling method.

[0027] Specifically, the temperature measuring and cooling component 9 includes several sets of symmetrically distributed arc mounting blocks 901, with the arc mounting blocks 901 facing each other in pairs, and the two arc mounting blocks 901 combined to form a closed circumference. Multiple infrared temperature sensors 902 and atomizing nozzle groups 903 are embedded and fixedly installed on the arc mounting block 901. The infrared temperature sensors 902 are used to detect the temperature at various locations inside the die 4, including the threaded positions. The atomizing nozzle groups 903 are used to spray atomized droplets to local high temperatures. The atomizing nozzle groups 903 are symmetrically distributed in pairs above and below the infrared temperature sensors 902.

[0028] Two movable plates 7 support the air-cooling kit 8 and the temperature measuring and cooling component 9. After a single glass bottle is made, the die 4 flips back and returns above the bottom mold 5. At this time, the hydraulic cylinder 6 needs to lower the bottom mold 5 to a certain height to accommodate the movable plates 7. Then, driven by the electric push rod 10, the two movable plates 7 move quickly and synchronously above the bottom mold 5, so that they are positioned directly above the bottom mold 5 and below the die 4. After the two movable plates 7 close, the arc mounting block 901 closes together. After the die 4 comes above the movable plates 7, multiple infrared temperature sensors 902 on the arc mounting block 901 complete the temperature detection of the inside of the die 4. The testing includes checking the threads inside the die 4. If the local temperature is higher, the atomizing nozzle group 903 at that location should spray atomized droplets. When the local temperature is high, spraying can be continuous. When the temperature difference is small, spraying should be intermittent. The heat on the die 4 evaporates the droplets and carries away the temperature of the high-temperature area inside the die 4. Combined with the hot air blown out by the air outlet pipe 803, the local cooling action can be completed well. In this way, the cooling and equalization work inside the die 4 can be well completed. Combined with the cooling system built into the die 4, the cooling can be completed quickly, and the bottle mouth can be pressed with a uniform temperature.

[0029] The atomizing nozzle group 903 is symmetrically positioned with infrared temperature sensors 902 distributed vertically. The circumference diameter formed by the two arc mounting blocks 901 needs to be smaller than the inner wall diameter of the die 4. A clearance space is preset on the side of the die 4's reset path to avoid collision with the arc mounting blocks 901 when the die 4 moves down in a flipping motion. The spraying action of the atomizing nozzle group 903 can be controlled by a solenoid valve. The temperature difference between the atomizing nozzle group 903 and the infrared temperature sensor 902 controls which atomizing nozzle group 903 sprays atomized droplets. A shielding strip should be provided on the outer surface of the atomizing nozzle group 903 to prevent possible splashing of dirt after the droplets are sprayed.

[0030] It should be noted that after the air-cooled kit 8 and the temperature measuring and cooling component 9 have completed the cooling action, the electric push rod 10 will simultaneously pull back the two moving plates 7, and the hydraulic cylinder 6 will need to lift the bottom mold 5 to firmly fit the bottom mold 5 and the opening mold 4 together. Then the molten glass will fall down again to continue the pressure blowing operation.

[0031] Furthermore, the air-cooling kit 8 includes multiple sets of air-cooling sleeves 1 801 and 2 807 of the same specifications. After the air-cooling sleeves 1 801 and 2 807 are combined, they form a column. An air inlet pipe 808 is fixedly connected through the upper side of the air-cooling sleeve 1 801, and an air outlet pipe 803 is fixedly connected through the lower side of the air-cooling sleeve 2 807. Spiral half-slices 802 are fixedly installed on the inner walls of both the air-cooling sleeves 1 801 and 2 807. After the air-cooling sleeves 1 801 and 2 807 are combined, the spiral half-slices 802 of the air-cooling sleeves 1 801 and 2 807 together form a complete spiral flow guiding structure. The airflow entering from the air inlet pipe 808 can follow the spiral path of the two combined spiral half-slices 802, flow out from the lower air outlet pipe 803, and flow into the space between the temperature measuring and cooling component 9 and the die 4.

[0032] When the two movable plates 7 approach each other synchronously, the air-cooled sleeve 1 801 on one movable plate 7 and the air-cooled sleeve 2 807 on the other movable plate 7 will also close together synchronously, covering the bottom mold 5's actuating mechanism. At the same time, the air-cooled sleeve 1 801 and the air-cooled sleeve 2 807 can engage together and move downwards together under the drive of the cylinder 809. Then, air is introduced into the sealed space after the air-cooled sleeve 1 801 and the air-cooled sleeve 2 807 are closed through the air intake pipe 808. The airflow spirals downwards along the path of the combined spiral half-slice 802 until it flows outwards from the air outlet pipe 803. The side-flowing, spiraling airflow effectively removes heat from the bottom mold 5's actuating mechanism, causing the airflow temperature to rise. Subsequently, the hot air enters between the die 4 and the temperature measuring and cooling component 9. After the atomizing nozzle group 903 sprays atomized droplets, it helps evaporate the droplets, preventing droplet accumulation at the inner wall threads of the die 4, which would result in slow evaporation and droplet residue. At the same time, the airflow, combined with the atomized droplets, accelerates the evaporation rate and, to a certain extent, improves the cooling speed, preventing the die 4 from failing to evaporate the droplets quickly due to its own heat, thus preventing droplet accumulation.

[0033] Specifically, a thick-walled heat storage tube 805 and a temperature control valve 806 are fixedly connected to the outlet pipe 803, with the temperature control valve 806 located near the end of the outlet pipe 803.

[0034] The thick-walled heat storage tube 805 at the end of the exhaust pipe 803 helps to store heat, while the temperature control valve 806 restricts the outflow of low-heat airflow. When the airflow temperature is low, the valve core is closed, and the airflow circulates and heats up in the thick-walled heat storage tube 805. After the gas flow temperature gradually increases, the temperature control valve 806 opens the valve core to exhaust the gas. The thick-walled heat storage tube 805 and the temperature control valve 806 work together to allow the exhaust pipe 803 to release a hot airflow at a fixed temperature between the arc mounting block 901 and the die 4. This helps to fix the cooling effect that the airflow and droplets can produce, and avoids fluctuating cooling effects that would affect the cooling process of the die 4.

[0035] Among them, the temperature control valve 806 can be a self-operated high-temperature temperature control valve, which is more suitable for hot gas, or a shape memory alloy SMA temperature control valve, which is more suitable for small-diameter and low-flow pipelines. After the set temperature is reached in the cavity, the valve core can be opened to exhaust gas. Generally speaking, the temperature control valve 806 is sufficient to withstand the increase in gas pressure. If you are worried about excessive pressure, you can connect a pressure relief valve in parallel to ensure pipeline safety.

[0036] Specifically, cylinders 809 are fixedly connected to the sides of both the first air-cooled sleeve 801 and the second air-cooled sleeve 807 to control their positions. A winding wheel 804 is installed in the middle of the air outlet pipe 803, and the air outlet pipe 803 is wound around the winding wheel 804.

[0037] The bottom mold 5 and the action mechanism on the bottom mold 5 are located below the moving plate 7. The cylinder 809 is used to control the air-cooling sleeve 1 801 and the air-cooling sleeve 2 807 to move down a certain distance in a synchronous manner, and to dissipate heat from top to bottom on the action mechanism of the bottom mold 5. Because the action mechanism of the bottom mold 5 contacts the molten glass first and will also squeeze the molten glass, the temperature above is higher. Combined with the air cooling of the bottom mold 5 itself, the heat dissipation of the bottom mold 5 can be completed effectively and quickly.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
