Technical Field
[0001] The utility model relates to the technical field of aluminum-plastic cover preparation, in particular to an aluminum-plastic cover riveting preheating temperature control device. Background Art
[0002] The riveting of the aluminum cover and the plastic cover in the aluminum-plastic cover is to use the riveting head to stamp and rivet the aligned aluminum cover and the plastic cover to form a connection in the form of a flange or a breakpoint between the aluminum cover and the plastic cover. Before the aluminum cover and the plastic cover are riveted, the plastic cover needs to be heated to improve the plasticity of the plastic cover.
[0003] The existing heating device directly acts on the lower riveting column to increase the temperature of the riveting column and perform high-temperature riveting. However, when the riveting column is riveted, the riveting column needs to be in contact with the aluminum cover and the plastic cover for a certain period of time. The high-temperature riveting column is likely to cause damage to the plastic cover during long-term contact with the plastic cover, which can easily cause deformation of the plastic cover. Therefore, it is necessary to shorten the contact time between the riveting column and the aluminum cover and the plastic cover. Summary of the invention
[0004] The technical problem to be solved by the utility model is that when the riveting column is used to rivet the plastic cover and the aluminum cover, the long-term contact between the riveting column and the plastic cover and the aluminum cover easily causes the plastic cover to deform, thereby reducing the yield rate.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a preheating temperature control device for riveting aluminum-plastic cover, including a mounting frame fixed on the loading tray of the riveting device and a temperature sensor fixed on one side of the mounting frame, the output end of the temperature sensor faces the edge notch of the loading tray, a heating cylinder is fixedly arranged in the mounting frame, a connecting pipe is fixedly connected to the side wall of the heating cylinder, an air inlet pipe is connected to the top of the heating cylinder, and a nozzle is arranged at the bottom of the connecting pipe.
[0006] Preferably, the temperature sensor is located upstream of the connecting pipe, and the temperature sensor controls the electric heating structure connected to the inside of the heating cylinder.
[0007] Preferably, the connecting pipe is in an arc-shaped structure, and the outer diameter of the connecting pipe is the same as the outer diameter of the loading tray, and the nozzles are arranged equidistantly along the axial direction of the connecting pipe.
[0008] Preferably, an arc-shaped support plate is vertically fixedly provided on the bottom surface of the connecting tube, and when the connecting tube is fixedly connected to the heating cylinder, the support plate contacts the top surface of the bottom plate of the loading tray.
[0009] 1. The utility model provides a preheating temperature control device for riveting aluminum-plastic covers. The preheating temperature control device is installed on the loading plate of the riveting device, and the temperature of the unriveted aluminum-plastic cover is detected by a temperature sensor. According to the detected initial temperature, the power of the electric heating structure in the heating cylinder is adjusted, and then the temperature of the clean air sprayed from the nozzle is adjusted, so as to achieve heating of the plastic cover while avoiding damage to the plastic cover caused by high temperature, thereby improving the yield rate of the aluminum-plastic cover.
[0010] 2. Preheating the plastic cover through the preheating temperature control device can shorten the contact time between the riveting column of the subsequent riveting device and the aluminum-plastic cover, thereby increasing the rotation speed of the riveting device and thus improving the riveting efficiency of the aluminum-plastic cover.

[0015] like Figure 1 As shown, the utility model provides an aluminum-plastic cover riveting preheating temperature control device, including a mounting frame 1 fixed on a loading tray of the riveting device and a temperature sensor 3 fixed on one side of the mounting frame 1, the output end of the temperature sensor 3 faces the edge notch of the loading tray, a heating cylinder 2 is fixedly arranged in the mounting frame 1, a connecting pipe 5 is fixedly connected to the side wall of the heating cylinder 2, an air inlet pipe 4 is connected to the top of the heating cylinder 2, and an air nozzle 6 is arranged at the bottom of the connecting pipe 5.
[0016] The mounting frame 1 is fixedly mounted on the chassis of the feeding tray of the riveting device, ensuring that the mounting frame 1, the heating cylinder 2 and the connecting pipe 5 are in a vertical state, and the clean air is transported to the heating cylinder 2 through the air inlet pipe 4, and the clean air is heated by the electric heating structure in the heating cylinder 2. The heated air enters the connecting pipe 5 and is ejected through the nozzle 6 at the bottom of the connecting pipe 5. The ejected high-temperature clean air preheats the un-riveted aluminum-plastic cover at the edge of the feeding tray, so that the plastic cover reaches the set temperature, and then the feeding tray continues to rotate to transport the un-riveted aluminum-plastic cover to the riveting device to achieve the riveting of the aluminum-plastic cover.
[0017] like Figure 1 and Figure 2As shown, in order to improve the intelligence of preheating, the temperature sensor 3 is located upstream of the connecting pipe 5 , and the temperature sensor 3 controls the electric heating structure connected to the inside of the heating cylinder 2 .
[0018] The temperature sensor 3 is installed upstream of the connecting pipe 5. The temperature sensor 3 is used to monitor the temperature of the unriveted aluminum-plastic cover in the loading tray, and control the power of the electric heating component in the heating cylinder 2 according to the detected temperature to avoid high temperature damage to the plastic cover and reduce the energy consumption of the electric heating structure.
[0019] like Figure 1 and Figure 2 As shown, in order to achieve uniform heating of the unriveted plastic cover, the connecting pipe 5 is in an arc structure, and the outer diameter of the connecting pipe 5 is the same as the outer diameter of the loading tray, and the air jets 6 are arranged equidistantly along the axial direction of the connecting pipe 5 .
[0020] One end of the connecting pipe 5 passes through the mounting frame 1 and is fixedly connected to the heating cylinder 2. The connecting pipe 5 is arranged in an arc shape. During the feeding process of the loading tray, the plastic cover is continuously heated by the evenly arranged nozzles 6 to achieve uniform heating of the plastic cover.
[0021] like Figure 1 As shown, in order to improve the stability of the connecting pipe 5, an arc-shaped support plate is vertically fixed on the bottom surface of the connecting pipe 5. When the connecting pipe 5 is fixedly connected to the heating cylinder 2, the support plate contacts the top surface of the bottom plate of the loading tray. The bottom end of the support plate abuts against the bottom plate of the loading tray, and the support for the connecting pipe 5 is enhanced by the support plate. At the same time, the setting of the support plate can also prevent the aluminum-plastic cover on the edge of the loading tray from falling off.
