SUMMARY

[0003] The present application aims to overcome the above technical deficiencies, and provide a stable machine clamp adjusting mechanism which can make the clamping force of machine clamp assembly good and stable.

[0004] The purpose of the present application is achieved by the following technical scheme: a stable machine clamp adjusting mechanism, comprising a rotating disc shaft, a rotating disc seat, a rotating disc and a positioning seat are sequentially arranged on the rotating disc shaft from top to bottom, a fixed ring is arranged on the periphery of the positioning seat, the fixed ring has a high-low slope structure, a push wheel is arranged on the fixed ring, the push wheel is connected with a pressure wheel through a swing rod, the swing rod is arranged on a swing rod seat, the side of the pressure wheel is connected with a left machine clamp seat, the left machine clamp seat is connected with a right machine clamp seat, the left machine clamp seat is connected with a left machine clamp body, and the right machine clamp seat is connected with a right machine clamp body.

[0005] The left machine clamp seat and the right machine clamp seat are connected through engagement. A plurality of retaining rings are arranged on the periphery of the fixed ring. A height adjusting frame is arranged below the positioning seat through a lifting ring and a ring pin, the height adjusting frame is connected with a height adjusting power source through a push rod joint. An adjusting positioning frame is movably arranged between the other end of the height adjusting frame and the rotating disc seat.

[0006] After adopting the present application, the fixed ring has a high-low slope structure, so that the push wheel rolls on the ring surface of the fixed ring with an arc high position and an arc low position. When the push wheel falls from the high position ring surface to the low position ring surface, the swing rod swings to push the left machine clamp seat and drive the right machine clamp seat, so that the left machine clamp body and the right machine clamp body are in a stable open state with good clamping force, and the upper bag opening of the packaging bag is completely opened, which fully prepares for the next material filling. The lifting of the height adjusting frame can adjust the height of the positioning seat and the fixed ring, adapt to the opening of packaging bags of different specifications, and improve the packaging quality and working efficiency of the bag feeding packaging machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0008] Figure 1 It is a structural schematic diagram of the stable machine clamp adjustment mechanism of the present invention.

[0010] Figure 3 for Figure 1 A side view of the machine with the turntable, etc. removed (retaining a single machine clamp assembly). DETAILED DESCRIPTION

[0011] Reference Figures 1 to 3 It can be seen that the present invention is applied to a stable machine clamp adjustment mechanism of a bag-feeding packaging machine, comprising a turntable shaft 1 (including a turntable shaft sleeve), a turntable seat 2, on which a turntable 3 (rotating motion) and a positioning seat 4 (fixed on the turntable shaft sleeve) are sequentially installed from top to bottom. A fixing ring 5 is installed on the periphery of the positioning seat 4. The fixing ring 5 has a high and low slope structure (that is, the fixing ring has a slope structure with a part of the ring surface being higher and the other part of the ring surface being lower). There is a push wheel 6, which is equipped with a pressure wheel 8 via a rocker 7 (in the shape of a cross). The rocker 7 is mounted on a rocker seat 9 (the rocker seat 9 is located outside the rocker 7 and is mounted on the periphery of the turntable 3). The side of the pressure wheel 8 is connected to the left machine clamp seat 10, which is connected to the right machine clamp seat 12. The left machine clamp seat 10 is connected to the left machine clamp body 11 (including the left machine clamp head), and the right machine clamp seat 12 is connected to the right machine clamp body 13 (including the right machine clamp head). The left machine clamp seat 10 and the left machine clamp body 11, and the right machine clamp seat 12 and the right machine clamp body 13 form a machine clamp assembly, which is used in multiple groups to serve as multiple workstations of the bag feeding and packaging machine, such as bag loading, bag clamping, bag support, and filling. The push wheel 6, rocker 7, pressure wheel 8, and rocker seat 9 are also correspondingly several parts. The machine clamp assembly and rocker seat 9 are movably mounted on the periphery of the turntable 3.

[0012] The left machine clamping seat 10 and the right machine clamping seat 12 are connected by meshing. Figure 3 As shown. Two retaining rings 15 are installed around the periphery of the fixed ring 5 and are located between the lower positions of the partial annular surfaces of the fixed ring. Figure 1 、 Figure 2As shown, the height adjusting frame 14 is installed below the positioning seat 4 through the lifting ring 19 and the ring pin 20 (installed in the height adjusting frame), and is connected with the height adjusting power source 17 (an electric cylinder) through the push rod joint 16, so as to finely adjust the longitudinal height position of the positioning seat and the fixing ring to adapt to different specifications of the packaging bag. The height adjusting power source 17 works to drive the height adjusting frame 14 through the push rod joint 16, and then drives the positioning seat 4 to make lifting movement through the action of the lifting ring 19 and the ring pin 20. The adjusting positioning frame 18 is movably installed between the other end of the height adjusting frame 14 and the rotating disc seat 2, and serves as the adjusting fulcrum of the height adjusting frame.

[0013] As shown in the drawings, the working principle of the present application is that the rotating disc shaft 1 drives the rotating disc 3 to make rotating movement, and the machine clamp assembly, the push wheel 6, the swing rod 7, the pressing wheel 8, the swing rod seat 9 also make rotating movement with the rotating disc 3, and the positioning seat 4 is fixed. The push wheel 6 makes circular movement on the ring surface of the fixing ring 5. Since the fixing ring 5 has high-low slope structure, the push wheel makes high position rolling on the ring surface of the fixing ring for an arc (about 315 degrees) and makes low position rolling for another arc (about 45 degrees). When the push wheel 6 falls from the high position ring surface of the fixing ring 5 to the low position ring surface to make rolling, the swing rod 7 swings to make the pressing wheel 8 push the left machine clamp seat 10, and then drives the right machine clamp seat 12, so that the left machine clamp body 11 and the right machine clamp body 13 are in stable open state and have good clamping force, thereby completely opening the upper bag mouth of the packaging bag installed on the left and right machine clamp bodies to facilitate material filling.
