The top of the support plate 61 is provided with a flipping structure 7, and one side of the flipping structure 7 is provided with a clamp 10 and a clamp 11.

[0035] The pusher structure 8 includes a sector rack 2 81 arranged at the other end of the driven rod 65, the sector rack 2 81 and the sector rack 1 63 have a gear ratio of 1:1, and the sector rack 2 81 does not contact the turntable 66. The pusher structure 8 also includes a connecting plate 87 arranged on one side of the shaping machine 5, the connecting plate 87 is L-shaped, and a long plate 86 is arranged at one end of the connecting plate 87. The surface of the long plate 86 is provided with a slide groove, and a slider 84 is slidably connected to the inside of the slide groove. One end of the slider 84 A spring 85 is provided at the end, and one end of the spring 85 away from the slider 84 is connected to the slide groove, and a rack three 82 is provided on one side of the slider 84, and the rack three 82 is meshed with the fan-shaped rack two 81, and a push plate 83 is provided at one end of the rack three 82, and the rack three 82 and the push plate 83 are higher than the top surface of the pump cover. The push plate 83 is used to automatically push the pump cover on the top surface of the turntable 66 and the corresponding group of pump covers close to the shaping machine 5 to feed, thereby realizing automatic discharging of the pump cover after the shaping is completed, thereby improving production efficiency.

[0036] The guide structure 9 includes L-shaped plates 91 symmetrically arranged on both sides of the shaping machine 5. The two groups of L-shaped plates 91 are L-shaped, and one side of the two groups of L-shaped plates 91 is rotatably connected with a rotating shaft 93. The two groups of rotating shafts 93 are respectively provided with springs 92 at one end away from the L-shaped plates 91. The two groups of springs 92 are connected to the top surface of the shaping machine 5. The outer sides of the rotating shafts 93 are respectively provided with guide plates 94. The two groups of guide plates 94 are respectively rotatably connected with guide wheels 95 at one end away from the rotating shafts 93. The two groups of guide plates 94 and guide wheels 95 are initially in an eight-shaped state, which effectively guides and positions the pump cover, ensures that the pump cover can accurately and stably enter the shaping groove of the shaping machine 5, and improves the shaping effect and product quality.

[0037] Specifically, during use, the feeder 2 is first driven to move by the slide rail at the top of the support platform 1, and the clamping claw at one end of the feeder 2 clamps the pump cover and places it on the positioning platform 4, and the positioning platform 4 is fixed through the support frame 3. The existing suction cup at the other end of the feeder 2 adsorbs the pump cover on the positioning platform 4 and places it in the shaping groove of the shaping machine 5 for shaping. However, this pushing method makes the feeder 2 only able to feed one-to-one, which is inefficient. Based on the existing method, an improvement is made by providing a turntable 66 between the support frame 3 and the shaping machine 5 to increase the round-trip speed of the feeder 2, and the motor 62 at the top of the driving support plate 61 drives the fan-shaped rack 63 at the output end to rotate, and the fan-shaped rack The first gear 63 meshes with the driven wheel 64. Since the gear ratio of the sector rack 63 to the driven wheel 64 is 1:4, the sector rack 63 rotates one circle to drive the driven wheel 64 to rotate a quarter circle, so that the driven wheel 64 drives the driven rod 65 to rotate a quarter circle. The bottom end of the driven rod 65 is rotatably connected to the support plate 61, and the driven rod 65 drives the turntable 66 connected to the top to rotate a quarter circle, so that the pump cover is placed between the four groups of limit blocks 67 arranged at equal intervals on the top surface of the turntable 66, realizing batch processing and efficient circulation of the pump covers. The design of the turntable 66 enables the feeder 2 to process multiple pump covers at one time, and gradually feed the pump covers into the shaping machine 5 by rotating the turntable 66, greatly improving efficiency.

[0038] As the motor 62 rotates, the half gear 71 at the output end rotates half a circle and meshes with the rack 72. The rack 72 drives the short rack 73 to move toward the gear 74. The short rack 73 drives the protrusion on one side to slide in the groove of the fixed plate, and the protrusion is connected to the groove through a tension spring. At this time, the short rack 73 drives the protrusion to move and pull the tension spring to store force. The tension spring is used when the rack 72 is not meshed with the half gear 71. The rack 72 returns to its position through the tension spring, so that the short rack 73 meshes with the gear 74. The gear 74 drives the rotating rod 78 to rotate. The rotating rod 78 drives the clamping plate 10 at one end to rotate 180 degrees. The rotating rod 78 is rotatably connected to the side plates 79 at both ends. Since the clamp 11 set at one end of the clamping plate 10 clamps the already positioned pump cover after it is pushed out by the starting cylinder, the rotating rod 78 drives the clamped pump cover to rotate 180 degrees to the top of the turntable 66, so that the clamp 11 is loosened so that the pump cover is placed between the limit blocks 67. When the motor 62 drives the half gear 71 to rotate another half circle and mesh with the rack 2 75, the rack 2 75 drives the short rack 2 76 to move in the direction of the half gear 71. One end of the rack 2 75 extends out to the left side of the rotating rod 78. The short rack 2 76 at the top of the rack 2 75 is located on the left side of the rotating rod 78, so that the rack 2 75 drives the short rack 2 76 to move and mesh with the gear 2 77. The gear 2 77 drives the rotating rod 78 to reverse 180 degrees, so that the clamp 10 and the clamp 11 are reversed and returned to the two sides of the positioning platform 4. Since the turntable 66 is in a quarter rotation state, the motor 62 drives the half gear 71 to rotate one circle so that the pump cover is ejected from the positioning platform 4 through the cylinder and then clamped and discharged, realizing a seamless connection between the feeding and shaping process. When the pump cover is placed on the turntable 66, it is then pushed to the shaping machine 5 without additional waiting time.

[0039] At the same time, the driven rod 65 rotates to drive the sector rack 2 81 to rotate. The gear ratio of the sector rack 2 81 to the sector rack 1 63 is 1:1. In the process of rotating the turntable 66 by a quarter of a turn, the sector rack 2 81 meshes with the rack 3 82, and the rack 3 82 moves back to the direction away from the shaping machine 5. The slider 84 on one side is driven by the rack 3 to slide in the slide groove on the surface of the long plate 86. The slider 84 drives the spring 85 to compress and store force. The long plate 86 is fixed to the shaping machine 5 through the L-shaped connecting plate 87. The rack 3 82 drives the push plate 83 at one end to move to the side of the pump cover away from the shaping machine 5. The push plate 83 is in a pulled-back state. When the turntable 66 rotates by a quarter of a turn, the sector rack 2 81 is no longer meshed with the rack 3 82. The rack 3 82 drives the push plate 83 through the rebound force of the spring 85 to rotate the turntable 66 to the pump cover corresponding to the shaping machine 5 to push out the material. The pump cover is thereby pushed into the shaping groove of the shaping machine 5. Since an eight-shaped guide structure 9 is provided to guide the pump cover that is pushed out, as the push plate 83 pushes the pump cover into between the two groups of guide plates 94, it is pushed to both sides, so that the two groups of guide plates 94 rotate through the rotating shaft 93 on one side, and the rotating shaft 93 is rotatably connected to the L-shaped plate 91, and the L-shaped plate 91 is fixed to the shaping machine 5. The rotating shaft 93 is connected to the shaping machine 5 through the spring 92, so that the rotation of the rotating shaft 93 drives the spring 92 to twist, and the other end of the guide plate 94 is rotatably connected to the guide wheel 95 to avoid the pump cover from deviating when entering the shaping groove of the shaping machine 5, and automatically push the material at the same time, thereby realizing the automatic discharging of the pump cover after the shaping is completed, improving the production efficiency, effectively guiding and positioning the pump cover, ensuring that the pump cover can accurately and stably enter the shaping groove of the shaping machine 5, and improving the shaping effect and product quality.
