[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5This utility model provides an embodiment of a rapid unloading machine head, comprising a fixed plate 1, a feeding mechanism 2, a metal nut guide tube 3, heat insulation columns 4, nut heating blocks 5, a contact switch 6, a pushing mechanism 7, a bottom cover 8, and a rapid unloading mechanism 9. The feeding mechanism 2 includes a cylinder mounting plate 21. The top left end of the fixed plate 1 is fixedly connected to the cylinder mounting plate 21. The right side of the cylinder mounting plate 21 is fixedly connected to the feeding cylinder 22 and the guide rail of the linear guide rail 23. The bottom of the slider of the linear guide rail 23 is fixedly connected to the feeding needle 24. The middle inner wall of the fixed plate 1 is fixedly connected to the outer wall of the metal nut guide tube 3. The top ends of the heat insulation columns 4 are fixedly connected to the four corners of the fixed plate 1. The bottom ends of the four heat insulation columns 4 are fixedly connected to the nut heating blocks 5. The pushing mechanism 7 includes a pushing cylinder 71, a fixed plate 6, a pressing mechanism 7, a pressing mechanism 8, a pressing mechanism 9, a pressing mechanism 1, a pressing mechanism 1, a pressing mechanism 2 ... A pusher cylinder 71 is fixedly connected to the right side of plate 1, and a pusher block 72 is fixedly connected to the left side of the pusher cylinder 71. A contact switch 6 is fixedly connected to the bottom left end of the fixed plate 1. A bottom cover 8 is fixedly connected to the bottom of the nut heating block 5. The quick unloading mechanism 9 includes a quick unloading block 91. The quick unloading block 91 is slidably connected to the right side of the bottom cover 8. A quick-change feeding nozzle 93 is inserted into the bottom of the bottom cover 8. Both the bottom cover 8 and the quick unloading block 91 are slidably connected to quick-connect pins 92. Through the combined use of the feeding mechanism 2, the contact switch 6, and the pusher mechanism 7, the metal nut can be quickly and accurately installed in the plastic shell, greatly improving work efficiency and production quality. Defective products can be discharged through the quick unloading mechanism 9, and the installation and disassembly are convenient and quick, making it easy to use.
[0023] Furthermore, the linear guide 23 is located below the feeding cylinder 22. The piston rod of the feeding cylinder 22 is fixedly connected to the top of the slider of the linear guide 23. The slider of the linear guide 23 is driven to move downward through the cylinder mounting plate 21, so that the slider pushes out the feeding needle 24. The feeding needle 24 accurately inserts the nut into the screw post of the plastic shell.
[0024] Furthermore, the feeding needle 24 penetrates the fixing plate 1 and the nut heating block 5. The position of the quick-change feeding nozzle 93 corresponds to the position of the feeding needle 24. The diameter of the feeding needle 24 is smaller than the inner wall diameter of the quick-change feeding nozzle 93. After the metal nut is pushed above the quick-change feeding nozzle 93, the feeding needle 24 pushes the metal nut out from above the quick-change feeding nozzle 93. The quick-change feeding nozzle 93 can also be pulled down for quick disassembly.
[0025] Furthermore, the bottom outer wall of the metal nut guide tube 3 is fixedly connected to the inner wall of the nut heating block 5. The position of the quick unloading block 91 corresponds to the position of the metal nut guide tube 3. The metal nuts are stacked in batches through the metal nut guide tube 3 and enter the nut heating block 5 at the machine head. The bottommost nut rests against the quick unloading block 91. Two electric heating tubes 51 are fixedly connected in the middle of the nut heating block 5. The electric heating tubes 51 are connected to an external power source and are controlled by the control panel. When the electric heating tubes 51 are turned on, they heat the nut heating block 5. The maximum temperature can be heated to 350℃. The nut heating block 5 heats the metal nuts through heat conduction.
[0026] Furthermore, the contact switch 6 and the pusher block 72 are at the same horizontal position. The contact of the contact switch 6 is set on the side close to the pusher block 72. The contact switch 6 is electrically connected to the cylinder mounting plate 21. After the pusher block 72 pushes the nut in the slot out, the pusher block 72 contacts the switch of the contact switch 6, so that the contact switch 6 opens the cylinder mounting plate 21.
[0027] Furthermore, the pusher block 72 has a slot in the middle that is the same size as the nut. The pusher block 72 is slidably connected to the bottom cover 8. The quick unloading block 91 is located at the bottom of the pusher block 72, and the top of the quick unloading block 91 is flush with the top of the bottom cover 8. After the metal nut enters the nut heating block 5, the bottommost nut rests on the quick unloading block 91. When a defective metal nut enters the machine head, the defective product can be quickly discharged from the machine head by pulling out the quick pin 92 and pushing open the quick unloading block 91, so as to achieve the purpose of quickly handling abnormal situations.
[0028] Working principle:
[0029] In operation, metal nuts are fed in batches into the nut heating block 5 at the machine head through the metal nut guide tube 3, with the bottom nut resting against the quick unloading block 91. The electric heating tube 51 is activated, heating the nut heating block 5 to a maximum temperature of 350℃. The nut heating block 5 heats the metal nuts through heat conduction. The pusher cylinder 71 moves the pusher block 72, which in turn moves the nuts in the slots, allowing each nut to be ejected individually. The metal nuts are pushed above the quick-change unloading nozzle 93. When the pusher block 72 contacts the contact switch 6, the contact switch 6 activates the cylinder mounting plate 21. The cylinder mounting plate 21 then moves the slider of the linear guide rail 23 downwards, causing the slider to eject the ejector needle 24. The ejector needle 24 accurately inserts the nut into the screw post of the plastic shell. Because the metal nuts are already heated to a high temperature, combined with the cylinder mounting plate 21 and the ejector needle 24... By increasing the pressure on the metal nut, the metal nut can be easily heat-melted and implanted into the plastic-shell stud. Through the coordinated use of the feeding mechanism 2, contact switch 6, and pushing mechanism 7, the metal nut can be quickly and accurately installed in the plastic shell, greatly improving work efficiency and production quality, and making it easy to use. After the metal nut cools down, the heat-melted plastic is tightly bonded to the metal nut, thereby increasing the tensile strength of the nut. When a defective metal nut enters the machine head, the pushing block 72 may get stuck and fail to discharge, causing the machine head to stop due to material jamming, which seriously affects production. At this time, the defective product can be quickly discharged from the machine head by pulling out the quick-release pin 92 and pushing open the quick-discharge block 91, so as to quickly handle the abnormal situation. At the same time, the quick-change discharge nozzle 93 can also be pulled down for quick disassembly. The defective product can be discharged through the quick-discharge mechanism 9, and the installation and disassembly are convenient and quick, making it easy to use.
