[0002] In soft bag inspection equipment, it is usually necessary to use a soft bag clamp to clamp the soft bag for the convenience of transporting it or performing various soft bag inspection operations. The transmission soft bag clamp usually adopts a shaft joint structure, that is, an eight-shaped clamping structure. For example, the utility model patent with the authorization announcement number CN205045475U discloses a rotary soft bag clamp and discloses that "the clamp includes two clamping plates, the two clamping plates are hinged to each other through hanging ears, the piston rod of the clamp action cylinder connects the hinge points of the two hanging ears of the clamp, and when the clamp action cylinder is pushed out, the clamp clamps the soft bag, and when the piston rod of the clamp action cylinder shrinks to the original position, the clamp opens and releases the soft bag". The speed impulse of the clamp of this structure is uneven, which can easily cause bubbles to form in the soft bag, thereby causing detection errors. On the other hand, the uneven clamping force can easily cause the soft bag to shake, and the uneven reset of the soft bag body after being clamped can easily cause misdetection.

[0025] See also Figure 1-Figure 3 The present embodiment discloses a parallel opening and closing soft bag clamp, comprising two clamping frames 1 whose shapes match the soft bag to be clamped, and a clamping driving unit for driving the two clamping frames 1 to open and close in parallel. The soft bag clamp provided in the present embodiment is usually used in a soft bag detection device, and the soft bag is clamped by the clamp to perform a full range of foreign matter detection or leakage detection on the soft bag. Therefore, in the present embodiment, the soft bag clamp also includes a rotation driving unit for driving the clamping frame 1 to rotate.

[0026] In this embodiment, by providing a clamping frame 1 that matches the shape of the soft bag, and arranging the two clamping frames 1 to clamp the soft bag in a parallel opening and closing manner, it can ensure that the force is evenly applied on both sides and the top and bottom of the soft bag, thereby ensuring the accuracy of the detection.

[0027] In the description of this embodiment, one end of the clamping frame 1 is defined as the bottom end.

[0028] For details, see Figure 1 The two clamping frames 1 are arranged in parallel and are constructed as a frame-shaped structure matching the shape of the soft bag. The two clamping frames 1 can be driven by the clamping drive unit to move synchronously in opposite directions, that is, to move closer to each other or farther away from each other. Figure 5 In order to ensure the clamping force of the soft bag, the clamping frame 1 is also fixedly connected with multiple sets of parallel compression ropes 2 along the width direction. The compression ropes 2 are respectively arranged on the opposite sides of the two clamping frames 1. In order to make the compression ropes 2 play a compression effect, the side ends of the clamping frames 1 are also fixedly connected with guide strips 3 for raising the compression ropes 2. Furthermore, the two clamping frames 1 are also connected with anti-skid pads 4 at the positions corresponding to the shoulders of the soft bag. The anti-skid pads 4 are provided with anti-skid patterns, and each clamping frame 1 is respectively connected with two anti-skid pads 4 to further enhance the clamping effect of the soft bag.

[0029] See also Figure 2 , Figure 3 The rotation driving part includes a rotation driving member and a rotation transmission assembly connected to the output end of the rotation driving member. The rotation driving member includes a driving motor 5 and a reducer 6 connected to the output end of the driving motor 5. The rotation driving member is fixedly mounted on the mounting plate 7 of the soft bag detection device. The output end of the reducer 6 is fixedly connected to a pulley a8 and another pulley b9 driven by a synchronous belt 10. The rotation transmission assembly includes a bearing seat 11 that plays a supporting role, and a rotating shaft 13 that is rotatably connected to the inside of the bearing seat 11 through two sets of upper and lower bearings 12. One end of the rotating shaft 13 is fixedly connected to the pulley b9 by bolts, and the rotating shaft 13 can be driven to rotate by the rotation driving member. The other end of the rotating shaft 13 is used to connect the clamping frame 1, thereby driving the clamping frame 1 to rotate. It can be understood that in the rotation driving member, the pulley transmission structure can also be replaced by a gear or the like as a power transmission structure, which can be selected according to actual needs.

[0030] The clamping drive unit includes a clamping drive, a clamping transmission assembly, and an opening and closing assembly for driving the two clamping frames 1 to move and guide the movement. The clamping drive is fixedly connected to the other end of the pulley b9, and the clamping drive and the rotating shaft 13 are respectively connected to the two ends of the pulley b9. In this embodiment, the rotating shaft 13 is a hollow shaft, and the clamping transmission assembly includes a torsion bar 15 arranged in the hollow shaft. The top end of the torsion bar 15 is connected to the output end of the clamping drive through a coupling 14, and the torsion bar 15 is driven to rotate through the clamping drive. The other end of the torsion bar 15 is connected to the opening and closing assembly, and the two clamping frames 1 are driven to move through the cooperation of the torsion bar 15 and the opening and closing assembly.

[0031] Specific, combined Figure 4The opening and closing assembly includes two vertically arranged upright plates 16, with a certain distance between the two upright plates 16, and a bottom plate 17 is connected between the upper ends of the two upright plates 16, and the bottom plate 17 is arranged below the bearing seat 11.

The top end of one of the sliders 19 is fixedly connected to a first pin 20, and is rotatably connected to a first connecting rod 21 via the first pin 20; the top end of the other slider 19 is fixedly connected to a second pin 22, and is rotatably connected to a second connecting rod 23 via the second pin 22; the other ends of the first connecting rod 21 and the second connecting rod 23 are rotatably connected to a third connecting rod 24; the first connecting rod 21 and the second connecting rod 23 are respectively arranged at two ends of the third connecting rod 24; by twisting the center position of the third connecting rod 24, the first connecting rod 21 and the second connecting rod 23 can be driven to move in opposite directions, thereby driving the two sliders 19 and the clamping frame 1 to move in opposite directions, thereby realizing a parallel opening and closing action.

[0032] See again Figure 4 A sunken step 171 for connecting the rotating shaft 13 is provided on the bottom plate 17. A connecting flange is fixedly provided at the bottom end of the rotating shaft 13. The connecting flange is fixedly connected to the sunken step 171 by bolts.

Furthermore, the forward and reverse rotation of the torsion bar 15 can drive the third connecting rod 24 to twist in two directions, thereby driving the two sliders 19 and the clamping frame 1 to close or open. It should be noted that in this embodiment, the clamping drive member preferably has a rotary cylinder 25 with high-precision control capability. When the rotary cylinder 25 is used, in order to prevent the rotation of the rotary cylinder 25 from causing the trachea to twist, the other end of the rotary cylinder 25 is also connected to a pneumatic slip ring 26 through a slip ring mounting seat, and the fixed end of the pneumatic slip ring 26 is engaged with the rotating drive member through a Y-shaped anti-rotation plate 27. In other embodiments, the clamping drive member can also adopt an electric drive structure.

[0035] The soft bag clamp provided in this embodiment sets the rotating shaft 13 in the rotating driving part to be hollow, and sets the torsion bar 15 in the clamping driving part inside the hollow rotating shaft 13, which can make full use of the space and make the overall space of the device more compact. By setting the guide rod 18 and the slider 19 to cooperate and drive the two clamping frames 1 to open and close in parallel, on the one hand, the accuracy of the parallel movement is ensured, and on the other hand, the parallel opening and closing clamping method can ensure that the forces on both sides and the top and bottom of the soft bag are uniform, thereby ensuring the accuracy of the detection.
