[0002] In the bottle-making process, especially in the blow molding stage, the temperature of the gas has a crucial impact on the quality of the bottle. If the gas temperature is too low, it will cause the bottle to cool down too quickly when it comes into contact with the heated preform or raw materials, which can easily lead to defects such as bottle deformation, uneven wall thickness, and surface wrinkles. If the gas temperature is too high, it may cause localized overheating of the bottle, affecting its physical properties.

The gas heating mechanism 2 includes a heating box 21 fixedly connected to the top of the load-bearing plate 1.

[0020] The specific setup and function of its gas heating mechanism 2 and lifting and stabilizing mechanism 3 will be explained below.

[0021] In this embodiment, the gas heating mechanism 2 includes a temperature sensor 22 and a finned heating tube 23, which are fixedly connected inside the heating box 21.

[0022] An air inlet 24 is fixedly connected to the outer surface of the heating box 21. A sliding groove 25 is opened inside the air inlet 24.

One end of the air inlet pipe 27 passes through the inside of the heating box 21, and the other end of the air inlet pipe 27 is connected to an external air source. A fixing frame 28 is fixedly connected to the inner bottom wall of the heating box 21. Finned heating tubes 23 are fixedly connected to the inside of the fixing frame 28 at three equal intervals.

[0023] The effects achieved by the above components are as follows: the temperature sensor 22 can monitor the gas temperature in the heating chamber 21 in real time, providing accurate data support for temperature control and ensuring that the gas temperature meets the bottle-making requirements; the finned heating tube 23 is fixed by the fixing frame 28 at three equal intervals, which can make the temperature distribution in the heating chamber 21 uniform, improve heating efficiency, and quickly heat the gas to the target temperature; the air inlet 24 provides a channel for gas to enter; the sliding groove 25 facilitates the installation and replacement of the filter plate 26; the filter plate 26 can effectively filter impurities and moisture in the gas, preventing impurities from entering the heating chamber 21 and affecting the heating effect and contaminating the bottle.

[0024] Specifically, an exhaust pipe 29 is fixedly connected to the top of the heating box 21, a one-way valve 210 is fixedly connected to the top of the exhaust pipe 29, and a pressure gauge 211 is fixedly connected to one side of the outer surface of the one-way valve 210.

[0025] The above components achieve the following effects: the gas outlet pipe 29 is the channel for the heated gas to flow out of the heating box 21, ensuring that the gas is smoothly delivered to the subsequent stages; the one-way valve 210 can prevent the heated gas from flowing back, ensuring unidirectional gas flow, maintaining stable pressure inside the heating box 21, and avoiding a decrease in heating efficiency due to backflow; the pressure gauge 211 can display the gas pressure in real time, which is convenient for operators to monitor, and can take timely measures when the pressure is abnormal to ensure the safe and stable operation of the device.

[0026] Specifically, an air outlet 212 is fixedly connected to the other side of the outer surface of the one-way valve 210. A connecting hose 213 is snapped onto the outer surface of the air outlet 212. A connecting clamp 214 is snapped onto the outer surface of the connecting hose 213. Connecting parts 215 are threaded onto both sides of the connecting clamp 214. The connecting hose 213 is snapped onto the outer surface of the connecting hose 213 through the connecting clamp 214.

[0027] The effects achieved by the above components are as follows: the gas outlet 212 is the key interface for gas output from the device to the bottle making machine; the connecting hose 213 has good flexibility and can be flexibly adapted to the gas interface position of the bottle making machine; the connecting clamp 214 and the connector 215 work together to firmly clamp the connecting hose 213 onto the gas outlet 212, ensuring a tight seal at the connection, preventing gas leakage, and ensuring the stability and efficiency of gas delivery.

[0028] Specifically, an inspection port 216 is provided on the outer surface of the heating box 21. A sealing gasket 217 is attached to the inner wall of the inspection port 216.

[0029] The effects achieved by the above components are as follows: the inspection port 216 provides a convenient passage for the inspection and maintenance of the internal components of the heating box 21, reducing the amount of disassembly work during maintenance; the sealing gasket 217 enhances the sealing between the protective door 218 and the heating box 21, preventing heat loss and gas leakage inside the heating box 21, improving energy utilization, and ensuring operational safety; the protective door 218 is fixed by the limiting member 219, which can effectively protect the internal components of the heating box 21, prevent external debris from entering, and facilitate opening for maintenance operations.

[0030] Specifically, the lifting and stabilizing mechanism 3 includes a rotating plate 31 threadedly connected to the bottom of the load-bearing plate 1, a cross lifting plate 32 rotatably connected to the bottom of the rotating plate 31, a rotating meniscus 33 rotatably connected to the bottom of the cross lifting plate 32, a rotating assembly 34 fixedly connected to the bottom of the rotating meniscus 33, a stabilizing base plate 35 fixedly connected to the bottom of the rotating assembly 34, and connecting bolts 36 threadedly connected to both sides of the stabilizing base plate 35.

[0031] The effects achieved by the above components are as follows: the rotating plate 31 is threadedly connected to the load-bearing plate 1, providing stable support for the cross lifting plate 32. The cross lifting plate 32 can achieve lifting and lowering movement under the drive of the rotating component 34, thereby adjusting the height of the load-bearing plate 1 and the gas heating mechanism 2 to adapt to the gas interface height of different models of bottle making machines. The rotating half-moon plate 33 reduces the frictional resistance of the cross lifting plate 32 during lifting and lowering, making the lifting process smoother. The stable base plate 35 increases the contact area between the device and the ground, and together with the connecting bolts 36, the device is firmly fixed to the ground, improving the overall stability of the device and preventing the device from shaking or tipping over during operation.

[0032] Specifically, the rotating assembly 34 includes a servo motor 341 fixedly connected to the top of the stabilizing base plate 35. The output end of the servo motor 341 is fixedly connected to a main rotating shaft 342. A belt 343 is rotatably connected to the outer surface of the main rotating shaft 342. A secondary rotating shaft 344 is rotatably connected inside the belt 343. The secondary rotating shaft 344 rotates synchronously with the main rotating shaft 342 through the belt 343.

[0033] The effects achieved by the above components are as follows: the servo motor 341 provides power for the lifting motion, with stable speed and wide speed range, and can accurately control the lifting speed and height. The main rotating shaft 342 rotates under the drive of the servo motor 341, and drives the rotating shaft 344 to rotate synchronously through the belt 343, realizing the transmission and distribution of power, ensuring that the lifting motion on both sides of the cross lifting plate 32 is coordinated and consistent, and ensuring that the device lifts and lowers smoothly.

[0034] Specifically, a rotating threaded rod 345 is rotatably connected to the outer surface of the main rotating shaft 342 and the driven rotating shaft 344. A bearing 346 is rotatably connected to the far end of the rotating threaded rod 345. The outer surface of the bearing 346 is fitted into the interior of the stabilizing base plate 35.

[0035] The effects achieved by the above components are as follows: the rotating threaded rod 345 rotates under the drive of the main rotating shaft 342 and the driven rotating shaft 344, and the lifting of the cross lifting plate 32 is realized through thread transmission. Its thread precision is high, which can realize the precise adjustment of the device height. The bearing 346 reduces the radial runout and frictional resistance when the rotating threaded rod 345 rotates, ensuring the smooth rotation of the rotating threaded rod 345, extending the service life of the components, and improving the accuracy of lifting adjustment.

[0036] Working principle: During use, the stable base plate 35 is fixed to the ground by connecting bolts 36 to ensure the overall stability of the device. According to the height of the gas interface of the bottle making machine, the servo motor 341 is started. The servo motor 341 drives the main rotating shaft 342 to rotate. The main rotating shaft 342 drives the driven rotating shaft 344 to rotate synchronously through the belt 343. The main rotating shaft 342 and the driven rotating shaft 344 drive the rotating threaded rod 345 to rotate. Under the action of the rotating threaded rod 345 and the cross lifting plate 32, the height of the load-bearing plate 1 and the gas heating mechanism 2 are adjusted to match the height of the gas interface of the bottle making machine. Gas from an external gas source enters the inlet 24 through the inlet pipe 27. After being filtered by the filter screen 26 to remove impurities and moisture, the gas enters the heating chamber 21. The temperature sensor 22 monitors the gas temperature inside the heating chamber 21 in real time. When the gas temperature is lower than the target value, the finned heating tube 23 operates to heat the gas until the target temperature is reached. The heated gas flows out through the outlet pipe 29. The one-way valve 210 prevents the gas from flowing back. The pressure gauge 211 displays the gas pressure in real time. Finally, the gas is delivered to the bottle making machine through the outlet 212 and the connecting hose 213, providing gas at a suitable temperature for the blow molding and other processes of the bottle making machine.

[0037] When it is necessary to inspect the internal components of the heating chamber 21, loosen the limit piece 219, open the protective door 218, and carry out the inspection operation through the inspection port 216. After the inspection is completed, close the protective door 218 and tighten the limit piece 219.
