Under the guidance of the guide plate 38, the copper tubes are evenly arranged on the support plate 37. A flap 39 is further hinged on the guide plate 38. A torsion spring is further provided between the flap 39 and the guide plate 38. Under the limitation of the flap 39, the copper tube cannot slide off the support plate 37 under the action of its own gravity.

A loading cylinder 310 is installed on the mounting rod 35 through a pushing rack 312. The loading cylinder 310 is tilted, and a loading plate 311 is also provided on the telescopic end of the loading cylinder 310 to push the copper tubes away from the support plate 37.

The loading plate 311 is reset to push the copper tubes on the support plate 37 backwards to prevent the copper tubes from being stacked and stuck between the support plate 37 and the guide plate 38.

[0032] A material transfer assembly 4 is provided between the loading assembly 3 and the frame 1; like Fig.10 As shown, the material transfer component 4 includes a support plate 41 and a material transfer frame 44. The support plate 41 is located between the loading component 3 and the frame 1. The support plate 41 is provided with two groups. The bottoms of the two groups of support plates 41 are provided with telescopic cylinders 42 that drive them to move in the Z-axis direction. The support plate 41 is also provided with a bracket 46 for supporting the copper tube. Driven by the telescopic cylinder 42, the support plate 41 is initially located below the support plate 37, so that the copper tube falls into the bracket 46 on the support plate 41. When transferring materials, the support plate 41 is located above the sliding die seat 92 to place the copper tube on the sliding die seat 92; the material transfer frame 44 is installed on the frame 1, and a material transfer cylinder 45 is provided on the material transfer frame 44.

[0033] The front side of the frame 1 is provided with a discharge assembly 10 for automatically discharging the filled copper tubes.

[0034] like Figure 7 As shown, the unloading assembly 10 includes a unloading plate 101 and a mounting seat 104, the mounting seat 104 is arranged on the front side of the frame 1, and a unloading rotating rod 103 is rotatably connected to the mounting seat 104, the longitudinal section of the unloading rotating rod 103 is hexagonal, and the unloading rotating rod 103 is driven by a unloading motor. The unloading rotating rod 103 is connected to the unloading plate 101 through the unloading seat 102, and the unloading plate 101 is provided with two groups, and is symmetrically arranged on both sides of the sliding mold base 92.

[0035] Working principle of the present invention: When in use, the device is connected to electricity and connected to an external PLC control center, and the PLC control center controls the opening and closing of the electrical components in the device; The staff loads the copper tube to be filled through the loading assembly 3. The copper tube is placed between the support plate 37 and the guide plate 38, and the support plate 37 is tilted. The copper tube slides along the support plate 37 under the action of its own gravity. The guide plate 38 can arrange the copper tubes one by one on the support plate 37 to avoid stacking. The copper tube rolls to the hinge of the guide plate 38 and the flap 39 under the action of its own gravity. Under the limit of the flap 39, the copper tube stays on the support plate 37, and the loading motor 33 is controlled to work, driving the loading rotating rod 32 to rotate, thereby driving the shifting block 36 to rotate. The shifting block 36 pushes the copper tube to move downward along the support plate 37, driving the flap 39 to rotate around the hinge with the guide plate 38, and the torsion spring accumulates force. At this time, the copper tube stops moving under the limit of the flap 39 and the torsion spring. The feeding cylinder 310 is controlled to extend, driving the feeding plate 311 to move toward the copper tube, and pushing a group of copper tubes to move toward the frame 1 (moving forward on the support plate 37). During the movement of the copper tube, the flap 39 rotates around the guide plate 38, and the torsion spring accumulates force again. When the pushed copper tube is separated from the flap 39, the flap 39 is reset for the first time under the action of the torsion spring, pressing the subsequent copper tube to prevent the subsequent copper tube from moving. The pushed copper tube rolls onto the support plate 41 in the transfer assembly 4 and is embedded in the bracket 46. The feeding cylinder 310 is controlled to reset. When the feeding plate 311 is reset, the copper tube on the support plate 37 is driven to move backward, effectively preventing the copper tube from being stuck between the support plate 37 and the guide plate 38. The flap 39 is reset for the second time under the action of the torsion spring, and the copper tube moves to the hinge of the flap 39 and the guide plate 38 under the action of its own gravity, waiting for the next feeding operation. The support plate 41 is provided with multiple groups of brackets 46. The copper tubes cannot fall accurately in the brackets 46. The material transfer cylinder 45 is controlled to work and extend, driving the swing plate 43 to move downward. The swing plate 43 is provided with an inclined surface at the bottom. Under the action of the inclined surface, the copper tubes are evenly arranged in the brackets 46. The material transfer cylinder 45 is controlled to reset, and the telescopic cylinder 42 is controlled to work and extend, so as to drive the support plate 41 to move upward, so that the support plate 41 is located above the limit mold 9. The moving cylinder 81 is controlled to work and extend, and the sliding mold base 92 is driven to move through the moving connecting rod 82 and the moving connecting plate 83. The moving trajectory of the sliding mold base 92 is an inclined straight line. When the support plate 41 and the sliding mold base 92 are located at the same longitudinal section, the telescopic cylinder 42 is controlled to reset, and the copper tube is driven to move downward, and the copper tube is placed in the mounting groove 95 on the sliding mold base 92. The moving cylinder 81 is controlled to reset. Since the moving cylinder 81 is tilted, when the moving cylinder 81 drives the sliding mold base 92 to reset, the copper tube on the sliding mold base 92 falls into the mounting groove 95 on the left mold base 91 and the right mold base 93, and the feeding and transfer of the copper tube are completed. The end face cylinder 64 in the control end face assembly 6 is extended to drive the end face block 61 to move downward, so that the feeding hole 62 corresponds to the position of the copper tube, and the feeding hole 62 corresponds to the output end position of the filling device 2. The ejection cylinder 53 is controlled to extend to drive the ejection connecting plate 54 to slide in the sliding groove 94 on the right die base 93. The copper tube ejection rod 55 drives the ejection plate 51 to tighten and limit the copper tube, and at the same time, the copper tube is attached to the end face block 61. The limit cylinder 73 is controlled to work, driving the pressing plate 74 to move downward, and the copper tube is pressed and limited; Control the filling device 2 to work, and fill the material in the filling device 2 into the copper tube. Since the copper tube is long and the filling pressure is large, after the material contacts the ejection plate 51, it will push the ejection plate 51 to move to the right. At this time, the spring 56 plays a role of buffering and maintaining pressure to prevent the ejection cylinder 53 from being damaged by impact. After the filling is completed, each component is controlled to reset. When the end block 61 moves upward, the end block 61 scrapes the left end of the copper tube to prevent material from falling from the left end of the copper tube; the unloading motor is controlled to drive the unloading rotating rod 103 to rotate on the mounting seat 104, and at the same time drive the unloading plate 101 to rotate, and the copper tube after filling is ejected from the mounting groove 95 on the limiting mold 9, and rolls along the unloading plate 101 to complete the unloading operation of the copper tube. Repeating the above steps can realize automatic loading, filling and unloading processing of the copper tube.
