DETAILED DESCRIPTION

[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1As shown, the device for placing the zipper head into the mold includes a fixed base plate 51, two zipper head conveying mechanisms 60, two zipper head arranging mechanisms 70, a zipper head pressing mechanism 80, a template conveying mechanism 90 and two zipper vibration plates 95. The fixed base plate 51 extends longitudinally to provide an installation basis for the above-mentioned other mechanisms.

[0034] like Figure 2 and 3As shown, the zipper head conveying mechanism 60 is used to output the received zipper heads 50 to the downstream mechanism at a predetermined rate and a predetermined number. Two zipper head conveying mechanisms 60 are symmetrically arranged above the fixed substrate 51. The zipper head conveying mechanism 60 includes a first fixed frame 61, a first cylinder 62, a first slide rail 63, a first shift block 64, a first stopper 65, a zipper head guide rail 66 and a zipper head release device. The two first fixed frames 61 are symmetrically arranged and respectively connected to the corresponding second fixed frames 71. The two first fixed frames 61 are connected by a connecting member, and the connecting member connects the two second fixed frames 71 into a whole, which effectively improves the structural strength of the fixed frame. A first hollow window is provided on the first fixed frame 61, and the first hollow window allows the piston rod of the first cylinder 62 to be inserted under the first fixed frame 61. The first cylinder 62 is arranged on the upper part of the first fixed frame 61. The first cylinder 62 is used to drive the first shift block 64 to move, so as to shift the pull tab of the zipper head 50 from a drooping state to a horizontal state. The first slide rail 63 is arranged on the first fixed frame 61, and the first slide rail 63 forms an acute angle with the horizontal plane. The first slide rail 63 is provided with a first slider which is slidably matched with the first slide rail 63. The piston rod of the first cylinder 62 passes through the first hollow window and is connected with the first slider. The zipper head guide rail 66 is used to provide a guide for the movement of the zipper head 50. The zipper head guide rail 66 includes a horizontal guide rail 661 and a slide groove 662. The horizontal guide rail 661 is a strip-shaped sheet structure. The horizontal guide rail 661 is horizontally arranged and extends in the longitudinal direction. The horizontal guide rail 661 is driven by the zipper vibration disk 95 to vibrate, thereby driving the zipper head 50 on the horizontal guide rail 661 to move along the length direction of the horizontal guide rail 661. The horizontal guide rail 661 is located at one side of the first fixed frame 61 and is movably connected to the first fixed frame 61. A second hollow window 67 is provided at one end of the horizontal guide rail 661 close to the first fixed frame 61. The second hollow window 67 can be used for the first shift block 64 to extend out. The slide groove 662 is vertically arranged. The slide groove 662 has a groove-shaped structure. After the zipper head 50 moves to the end of the horizontal guide rail 661, it slides downward along the slide groove 662. The upper end of the slide groove 662 is connected to the end of the horizontal guide rail 661 close to the first fixed frame 61, and the lower end of the slide groove 662 extends downward to the top of the zipper head fixed block 74. The first shift block 64 is located below the first fixed frame 61. One end of the first shift block 64 is connected to the piston rod of the first cylinder 62, and the other end of the first shift block 64 extends out from the second hollow window 67. The first stopper 65 is an inverted U-shaped block, which is located above the horizontal guide rail 661 and connected to the first fixing frame 61. The position of the first stopper 65 corresponds to the position of the second hollow window 67. When the zipper head 50 moves horizontally along the longitudinal direction on the flat guide rail 661, the pull tab of the zipper head 50 is in a drooping state. When the zipper head 50 moves to the bottom of the first stopper 65, the piston rod of the first cylinder 62 extends, driving the other end of the first shifting block 64 to extend from the second hollow window 67, shifting the pull tab of the zipper head 50 from the drooping state to the horizontal state.

[0035] The zipper head release device includes a first zipper head release cylinder 68 and a second zipper head release cylinder 69. The first zipper head release cylinder 68 and the second zipper head release cylinder 69 are arranged in parallel on the first fixed frame 61, wherein the second zipper head release cylinder 69 is located on the side of the first zipper head release cylinder 68 away from the first cylinder 62. The first zipper head release cylinder 68 and the second zipper head release cylinder 69 control the zipper head 50 to enter the slide groove 662 by controlling the extension and retraction of their piston rods. When the piston rod of the first zipper head release cylinder 68 is extended and the piston rod of the second zipper head release cylinder 69 is retracted, the zipper head 50 after passing through the first zipper head release cylinder 68 will enter the slide groove 662 and fall; when the piston rod of the first zipper head release cylinder 68 is retracted and the piston rod of the second zipper head release cylinder 69 is extended, the piston rod of the second zipper head release cylinder 69 is extended to block the zipper head 50 on the horizontal guide rail 661, so that it is in a queue state on the horizontal guide rail 661.

[0036] like Figure 1 As shown, the zipper vibration disk 95 is used to make the zipper head 50 neatly arranged by vibration and drive the zipper head 50 to move on the horizontal guide rail 661. Two zipper vibration disks 95 are arranged at one end of the fixed base plate 51. The two zipper vibration disks 95 correspond to and cooperate with the two zipper head conveying mechanisms 60. Each zipper vibration disk 95 has a corresponding storage hopper for feeding it. The discharge port of the storage hopper is connected to the feed port of the zipper vibration disk 95, and the feed port of the zipper vibration disk 95 is connected to one end of the horizontal guide rail 661 away from the first fixed frame 61. When the zipper vibration disk 95 vibrates, the horizontal guide rail 661 vibrates along with the zipper vibration disk 95, and the zipper head 50 stuck on the horizontal guide rail 661 moves along the length direction of the horizontal guide rail 661 under the action of vibration. Since the zipper vibration disk 95 is an existing equipment directly purchased on the market and a commonly used equipment in industrial production, the internal structure of the zipper vibration disk 95 will not be described in detail here.

A plurality of zipper head ejector pins 771 are equidistantly provided at the other end of the sliding top plate 77. Each zipper head ejector pin 771 is inserted into each second positioning groove one by one. An acute angle is formed between the zipper head ejector pin 771 and the zipper head fixing block 74. The end of the zipper head ejector pin 771 away from the sliding top plate 77 is an inclined surface. When the first positioning groove 772 is opened, the first driving motor 72 rotates, and the zipper head fixing block 74 moves longitudinally with the cooperation of the first screw rod slider assembly 73, so that each first positioning groove 772 has a zipper head 50 entering. After the zipper head 50 is placed, the first driving motor 72 rotates again to transport the zipper head fixing block 74 to the position corresponding to the lower drawing mold plate 24, thereby preparing for the zipper head pressing mechanism 80 to press the zipper head 50 into the mold core.
