[0001] The utility model relates to the technical field of aluminum-plastic cover processing, in particular to an aluminum-plastic cover riveting system. Background Art

[0002] When preparing the aluminum-plastic cover, the aluminum cover and the plastic cover are loaded separately, the plastic cover is located at the bottom of the aluminum cover, the tip of the plastic cover on the back is inserted into the opening in the middle of the aluminum cover, and the aluminum cover and the plastic cover are uniformly transported to the hot riveting device through a turntable, the tip is heated and squeezed by a hot riveting head to melt the tip, and a disc-shaped limiting structure is formed on the top surface of the aluminum cover to achieve hot riveting of the aluminum-plastic cover.

[0003] During the existing hot riveting process of aluminum-plastic covers, the hot riveting head needs to melt and form the tip after rotating half a circle with the hot riveting device. Therefore, the temperature of the hot riveting head is extremely high, which not only makes the hot riveting device high in power but also causes incomplete hot melting of the tip. As a result, the rotation speed of the hot riveting device is slowed down during the hot riveting process, reducing production capacity. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the hot riveting device only heats the aluminum-plastic cover for half a circle, and the rotation speed of the hot riveting device is reduced for the consideration of the hot riveting quality of the aluminum-plastic cover, thereby resulting in lower production capacity.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an aluminum-plastic cover riveting system, including a transmission disk and a plastic cover loading tray, an aluminum cover loading tray and a hot riveting device which are sequentially connected to the transmission disk along the material flow direction on the transmission disk, a preheating component is arranged in the material flow direction between the aluminum cover loading tray and the hot riveting device, and an air supply system is arranged on the material troughs connected to the aluminum cover loading tray and the plastic cover loading tray respectively, and the air supply system is connected to the preheating component.

The air supply pipelines are arranged equidistantly on the material trough, and the output end of the air supply pipeline is arranged along the material flow direction.

[0009] Preferably, the air supply system is arranged between the plastic cover loading tray and the aluminum cover loading tray, and the material loading rotation direction in the plastic cover loading tray is opposite to the material loading rotation direction in the aluminum cover loading tray.

[0010] Preferably, a buffer block is provided on the transmission disk, and the buffer block is located downstream of the connection between the material trough and the transmission disk. The buffer block includes a bolt fixed in the middle, a coil spring sleeved on the bolt, and a wear-resistant ring sleeved on the outer wall of the coil spring.

[0011] 1. The utility model provides an aluminum-plastic cover riveting system, which arranges a preheating component on a transmission disk, heats the aluminum-plastic cover in advance through the preheating component, increases the temperature of the aluminum cover in the aluminum-plastic cover, and then moves the aluminum-plastic cover to a riveting device, which then performs hot riveting on the aluminum-plastic cover, shortening the time required for hot riveting by the riveting device, thereby increasing the rotation speed of the riveting device and the heat of the riveting head, thereby producing the effect of increasing production capacity and reducing the power of the riveting device.

[0012] 2. By arranging an air supply system on the material trough, the air supply system ensures that the materials in the material trough are closely following each other.

[0018] like Figure 1As shown, the utility model provides an aluminum-plastic cover riveting system, comprising a transmission tray 4 and a plastic cover loading tray 2, an aluminum cover loading tray 1 and a hot riveting device 5 which are sequentially connected to the transmission tray 4 along the material flow direction on the transmission tray 4, a preheating component is arranged in the material flow direction between the aluminum cover loading tray 1 and the hot riveting device 5, and an air supply system 6 is arranged on the material trough 3 which is respectively connected to the aluminum cover loading tray 1 and the plastic cover loading tray 2 with the transmission tray 4, and the air supply system 6 is connected to the preheating component.

[0019] The aluminum cover loading tray 1 and the plastic cover loading tray 2 both adopt vibrating loading trays, and the output pipes of the aluminum cover loading tray 1 and the plastic cover loading tray 2 are respectively inserted into the corresponding material trough 3, and the air supply pipelines of the air supply system 6 are arranged at the loading end, the middle part and the unloading end of the material trough 3, and the air supply pipeline supplies air to the material trough 3 to ensure the smooth flow of materials in the material trough 3; when the aluminum cover and the plastic cover enter the transmission tray 4, the plastic cover preferentially enters the limiting notch at the edge of the transmission tray 4, and then the aluminum cover enters the limiting notch and falls on the plastic cover, and due to the arrangement of the limiting notch, the tip of the back of the plastic cover is inserted into the aluminum cover In the opening in the middle, the aluminum cover and the plastic cover move synchronously with the rotation of the transmission disk 4. During the movement of the aluminum cover and the plastic cover, high-temperature clean gas is transported to them through the preheating component to increase the temperature of the aluminum cover and the plastic cover. The preheated aluminum cover and the plastic cover are further moved to the hot riveting device 5. In the process of the hot riveting device 5 driving the aluminum cover and the plastic cover to rotate, the hot anchor head at the edge of the hot riveting device 5 is pressed down to gradually melt the tip of the plastic cover and mold it into a disc structure at the outer layer of the opening in the middle of the aluminum cover, thereby realizing the hot riveting processing of the aluminum-plastic cover, and finally the aluminum-plastic cover is discharged as the hot riveting device 5 rotates.

[0020] like Figure 2 The preheating assembly includes a heating cylinder 43 vertically fixed on the transmission disk 4 , the output end at the bottom of the heating cylinder 43 is connected to an arc-shaped connecting pipe 45 , an exhaust hole is provided at the bottom of the connecting pipe 45 , and the exhaust hole is located just above the edge of the transmission disk 4 .

[0021] The heating cylinder 43 is vertically fixed and installed by the mounting frame 42 .

[0022] A support frame 41 is installed on the top of the transmission disk 4. In addition to being used for installing the drive motor, the support frame 41 can also play a certain sealing role. The air preheated by the aluminum-plastic cover can exchange heat with the support frame 41 to ensure the temperature around the transmission disk 4.

[0023] As the aluminum-plastic cover rotates with the transmission disk 4, the heating cylinder 43 heats the clean air input by the air supply system 6, and discharges the heated clean air directly toward the aluminum-plastic cover through the exhaust holes at the bottom of the connecting pipe 45, thereby preheating the aluminum-plastic cover; by arranging the connecting pipe 45 into an arc shape and arranging the exhaust holes at equal intervals, the aluminum-plastic cover can be heated multiple times, thereby ensuring the preheating effect of the aluminum-plastic cover.

[0024] like Figure 2 As shown, the effect of preheating is accurately controlled. The preheating assembly also includes a temperature sensor 44 arranged upstream of the heating cylinder 43. The requirement of hot riveting can be met by preheating the aluminum-plastic cover to a set temperature. Therefore, the temperature of the incoming material is detected by the temperature sensor 44, and the efficiency of the heating cylinder 43 is adjusted according to the temperature to avoid wasting heat energy.

[0025] like Figure 1 As shown, in order to ensure the continuous supply of materials and avoid the situation in which the production capacity is affected by the lack of materials due to the slow material flow rate during the processing of the hot riveting device 5. The top of the material trough 3 is arranged with slots along the axial direction, and the air supply system 6 includes a diverter and an air supply pipeline connected to the output end of the diverter. The air supply pipelines are arranged equidistantly on the material trough 3, and the output end of the air supply pipeline is arranged along the material flow direction. The clean air transmitted by the air source is diverted by the diverter, and the slots on the top of the material trough 3 ensure that the air output by the air supply pipeline can directly act on the material, push the material to move forward quickly, and ensure that there are aluminum covers and plastic covers in the edge limit slots of the transmission disk 4.

[0026] like Figure 1 As shown, in order to optimize the positional relationship of each device in the riveting system, the riveting system is controlled to be on a line, which is convenient for the staff to detect and maintain along the line. The air supply system is arranged between the plastic cover loading tray 2 and the aluminum cover loading tray 1, and the material loading rotation direction in the plastic cover loading tray 2 is opposite to the material loading rotation direction in the aluminum cover loading tray.

[0027] like Figure 2 As shown, in order to avoid the material in the trough 3 from getting stuck when entering the limiting notch of the transmission disc 4. The transmission disc 4 is provided with a buffer block 46, which is located downstream of the connection between the trough 3 and the transmission disc 4. The buffer block 46 includes a bolt fixed in the middle, a coil spring sleeved on the bolt, and a wear-resistant ring sleeved on the outer wall of the coil spring. When the aluminum cover or plastic cover is stuck at the connection between the trough 3 and the transmission disc 4, the coil spring of the buffer block 46 is offset relative to the bolt to provide a temporary storage position for the stuck material. When the next limiting notch moves to the connection, the coil spring can be elastically reset to push the material into the limiting slot hole to avoid the situation of material blocking at the connection.
