[0002] Among ceramic forming machines, roll forming equipment is a large category. With the development of technology, automated ceramic production equipment has gradually become the mainstream production equipment, mainly including forming devices, loading devices, drying devices, etc. Traditional drying devices are mostly drying in drying rooms, which have problems such as long drying time and easy damage to the blanks during transportation. At the same time, they also consume a lot of energy and have poor energy conservation and environmental protection. For example, the patent document with announcement number CN212146946U designs a double-layer structure on the roll-forming production line to save space and greatly improve the drying effect and efficiency. However, the above patent document does not automatically preheat and control the temperature of the inside and outside of the ceramic bottle blank during the primary and secondary drying of the ceramic bottle blank. For thicker ceramic bottle blanks, due to the thickness of the blank, it is difficult for the internal and external temperatures to reach consistency quickly, which will cause a large temperature gradient in the blank during the drying process, thereby causing stress concentration and increasing the risk of cracking of the blank. For this reason, a solution is now provided. Summary of the Invention

[0010] Furthermore, side support frames are fixedly provided on both sides of the pretreatment box, and an insulation plate is slidably provided on the inner wall of the side support frame.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-Figure 7 As shown in the figure, due to the thick green body, it is difficult for the internal and external temperatures to reach uniformity quickly, resulting in a large temperature gradient in the green body during the drying process, which in turn causes stress concentration and increases the risk of green body cracking. This problem can be solved by the following solution: In this embodiment, the ceramic wine bottle blank roll-forming secondary drying equipment based on intelligent temperature control includes a pretreatment box 1, a secondary drying box 2, and a chain rotary transmission device. The chain rotary transmission device is arranged inside the pretreatment box 1 and the secondary drying box 2 to transmit the ceramic blank. The pretreatment box 1 is sealed with the secondary drying box 2. The interior of the pretreatment box 1 is provided with a temperature control component for preheating the inside and outside of the ceramic bottle blank. The temperature control assembly includes an electric push rod 71 vertically inserted into the top of the pretreatment box 1. The protruding end of the electric push rod 71 is fixedly connected to a lifting integrated plate 74. A hot air blower 73 is also installed on the top of the pretreatment box 1. It belongs to the prior art and will not be described in detail here. It is only necessary that the pretreatment box 1 has the function of conveying hot air. The output end of the hot air blower 73 is provided with an elastic telescopic tube. A plurality of inverted U-tubes 76 are provided below the lifting integrated plate 74. The plurality of inverted U-tubes 76 are connected to each other through a transverse tube 75. The output end of the elastic telescopic tube is connected to one of the inverted U-tubes 76. It should be explained here that: in this embodiment, three sets of inverted U-tubes 76 are provided, and the specific number of inverted U-tubes 76 is set according to actual production; Both output ends of the inverted U-tube 76 are provided with preheating elements, which include a temperature control tube 81 connected to the inverted U-tube 76. An upper inner sleeve 82 is slidably provided below the temperature control tube 81. A lower inner sleeve 83 is connected to the lower portion of the upper inner sleeve 82 via multiple sets of connecting columns 86. The lower inner sleeve 83 slides with the temperature control tube 81. An upper air guide hole 87 is provided on the outer wall of the temperature control tube 81 on one side of the multiple sets of connecting columns 86. The output end of the upper air guide hole 87 is arranged obliquely downward from a position close to the center line of the temperature control tube 81 to a position away from the center line of the temperature control tube 81. An outer guide cover 84 and an inner guide cover 85 are fixedly mounted on the outer wall below the temperature control tube 81. The inner guide cover 85 is arranged inside the outer guide cover 84, and a preheating channel for the outer side of the ceramic body is formed between the outer guide cover 84 and the inner guide cover 85. The output end of the upper air guide hole 87 corresponds to the preheating channel for the outer side of the ceramic body. The power of the hot air blower 73 is controlled to the first gear, that is, the wind speed is less than the second gear, the thrust of the thrust spring 811 is greater than the air pressure, the lower inner sleeve 83 and the upper inner sleeve 82 move upward synchronously, the air outlet 88 is blocked by the temperature control tube 81, and the hot air blown out of the upper air guide hole 87 is discharged through the preheating channel outside the ceramic body, which not only preheats the outside of the ceramic body but also blows away the impurities on the outside; The circumferential outer wall of the lower inner sleeve 83 is provided with multiple groups of air outlet holes 88, which are arranged in a circular array relative to the centerline of the lower inner sleeve 83. A cone column 89 is sealed and mounted on the bottom of the lower inner sleeve 83. A lower air guide hole 810 is provided on the outer wall of the temperature control tube 81 located outside the cone column 89. The output end of the lower air guide hole 810 is arranged toward the inner wall of the inner guide cover 85. The bottom of the cone column 89 is connected to the temperature control tube 81 via a thrust spring 811. A pressure stabilizing hole 812 is provided on the bottom wall of the temperature control tube 81. The extended end of the electric push rod 71 pushes the lifting integrated plate 74 downward, turning on the hot air blower 73 in advance and controlling the power to the second gear. The temperature control tube 81 moves downward to the interior of the ceramic body. The pressure of the gas in the temperature control tube 81 is greater than the thrust of the thrust spring 811, pushing the vertebral column 89 downward. The vertebral column 89 drives the lower inner sleeve 83 to move downward, so that the air outlet 88 corresponds to the lower air guide hole 810. The hot air is transported to the outer wall of the inner guide cover 85 to preheat the interior of the ceramic body. Side support frames 721 are fixedly provided on both sides of the pretreatment box 1. Insulation plates 722 are slidably provided on the inner walls of the side support frames 721. The insulation plates 722 are located above the side support frames 721, and the tops of the insulation plates 722 are fixedly connected to the lifting integrated plate 74 via connecting plates 723. The extended end of the electric push rod 71 descends through the connecting plate 723 to simultaneously lower the heat preservation plate 722, thereby shielding the interior of the pretreatment box 1 and reducing the dissipation of residual heat inside the pretreatment box 1. The hot air blown out of the preheating channel outside the ceramic body can be used to preheat the outside of the ceramic body. It should be explained here that for thicker ceramic bodies, when preheating before secondary drying, it is not necessary to require the internal and external temperatures of the ceramic bottle body to be completely consistent, but the temperature difference should be within a controllable range to avoid excessive temperature difference causing cracking of the body. The specific preheating temperature needs to be set according to actual production; It should be supplemented in this embodiment that: preheating tooling 9 is installed on the inner walls of both sides of the pretreatment box 1, and the output end of the preheating tooling 9 is arranged toward the ceramic bottle body. It is a preheating tool for thin ceramic bottles, so that the temperature inside the pretreatment box 1 is higher than the external environment, but lower than the internal temperature of the secondary drying box 2. The preheating tooling 9 can be a hot air dryer in the prior art and can be replaced in actual application, as long as it can achieve the function of preheating the ceramic bottle body; Example 2: Please refer to Figure 1-Figure 2 、 Figure 6-Figure 7 As shown, the chain-type rotary transmission device includes two sets of sprockets 4 and two chains 3 that cooperate with the sprockets 4. The two chains 3 are commonly provided with multiple sets of ceramic seats 5, and the multiple sets of ceramic seats 5 are evenly distributed on the chains 3. A bottom connecting frame is provided below the two sprockets 4, and two sets of drive motors are provided on the side walls of the bottom connecting frame. The output end of the drive motor is fixedly connected to the center of the sprocket 4 through a drive shaft; Side baffles 6 are provided on both sides of the multiple ceramic seats 5, and the side baffles 6 are fixedly connected to the bottom connecting frame to shield both sides of the chain-type rotary transmission device to ensure the temperature of the drying ceramic body; In the present invention, it can be seen from the combination of Example 1 and Example 2 that: By controlling the electric push rod 71 and the hot air blower 73, preheating treatment and temperature control are achieved on both sides of the ceramic blank, so as to ensure that the internal and external temperatures of the blank are quickly consistent during the later drying treatment of the blank, avoiding stress concentration and blank cracking caused by temperature differences. In addition, by the downward shielding of the insulation board 722, the residual heat inside the pretreatment box 1 is utilized in conjunction with the hot air blown out from the preheating channel on the outside of the ceramic blank to jointly preheat the outside of the ceramic blank, thereby improving the drying and molding quality of the ceramic blank.

[0025] Working principle: Step 1: The ceramic green body after the primary drying is placed on the ceramic seat 5 by the manipulator. When the ceramic seat 5 enters the interior of the pretreatment box 1, the chain rotary transmission device stops conveying the ceramic green body. At this time, the extended end of the electric push rod 71 is controlled to push the lifting integrated plate 74 downward, the hot air blower 73 is turned on in advance, and the power is controlled to the second gear. The temperature control tube 81 moves downward to the interior of the ceramic green body. The pressure of the gas in the temperature control tube 81 is greater than the thrust of the thrust spring 811, which pushes the vertebral column 89 downward. The vertebral column 89 drives the lower inner sleeve 83 to move downward, so that the air outlet 88 corresponds to the lower air guide hole 810. The hot air is transported to the outer wall of the inner guide cover 85, which can not only preheat the interior of the ceramic green body but also avoid direct blowing of hot air, which increases the risk of cracking the ceramic green body. Step 2: After preheating, the extended end of the electric push rod 71 is immediately controlled to reset. At this time, the power of the hot air blower 73 is controlled to the first gear, that is, the wind speed is less than the second gear, the thrust of the thrust spring 811 is greater than the air pressure, the lower inner sleeve 83 and the upper inner sleeve 82 are synchronously moved upward, and the air outlet 88 is blocked by the temperature control tube 81. The hot air blown out of the upper air guide hole 87 is discharged through the preheating channel outside the ceramic body, which not only preheats the outside of the ceramic body, but also blows away the impurities on the outside. Before the ceramic body is secondary dried, the temperature inside the thicker ceramic body is preheated to ensure that the temperature inside and outside the body is quickly consistent, avoiding stress concentration and body cracking caused by temperature differences; Step 3: During the process of step 1 and step 2, the protruding end of the electric push rod 71 descends through the connecting plate 723 to synchronously lower the insulation plate 722, thereby shielding the interior of the pretreatment box 1, reducing the dissipation of residual heat inside the pretreatment box 1, and making the internal temperature of the pretreatment box 1 higher than the air temperature. In combination with the hot air blown out from the preheating channel on the outside of the ceramic blank, the outside of the ceramic blank is preheated together.

Obviously, many modifications and variations are possible based on the contents of this specification.
