It can be conceived that the diaphragm pump round material grabbing displacement mechanism further comprises other functional modules such as a transmission mechanism, a power supply device and the like, which are the technology known to the person skilled in the art and will not be described one by one here.

[0017] The support structure 10 comprises a fixed plate 11, a support plate 12 vertically fixed on the fixed plate 11 and two reinforcing plates 13 arranged on the fixed plate 11 and the support plate 12.

[0018] The fixed plate 11 is a rectangular mounting plate, and the plate surface is arranged vertically to the ground plane, which can be mounted on the operation platform of the flow line or can be mounted on the edge of the feeding and discharging device to serve as the support base plate of the main body structure and provide the mounting position.

[0019] The support plate 12 is arranged vertically to the fixed plate 11 and parallel to the ground plane to be used for mounting and fixing the lifting assembly 20.

[0020] The two reinforcing plates 13 are arranged in parallel and spaced apart from each other and are arranged vertically to the support plate 12 and the fixed plate 11 respectively to play the role of supporting and fixing between the support plate 12 and the fixed plate 11 and provide a more stable structure.

[0021] The lifting assembly 20 comprises a drive cylinder 21 arranged on the fixed plate 11, two groups of lifting slide rail assemblies 22 arranged on the reinforcing plates 13, a buffer plate 23 connecting the drive cylinder 21 and the lifting slide rail assemblies 22 and two buffers 24 arranged on the buffer plate 23.

[0022] The drive cylinder 21 is fixed on the fixed plate 11, and the driving direction of the driving end is vertically upward to drive the displacement assemblies 40 and the material taking clamping jaws 50 to move vertically in the vertical direction perpendicular to the ground.

[0023] Two groups of the lifting slide rail assemblies 22 are fixed on the two reinforcing plates 13 respectively and are located on the sides away from each other. The lifting slide rail assemblies 22 each include two lifting sliding blocks 221 fixed on the reinforcing plate 13 and a lifting slide rail 222 arranged on the two lifting sliding blocks 221. The sliding blocks 211 are arranged at intervals, and the extension direction of the slide rail 221 is consistent with the driving direction of the driving cylinder 21, so as to realize the lifting movement in the vertical direction.

[0024] The buffer plate 23 is connected to the driving end of the driving cylinder 21 and is fixedly connected with the end of the lifting slide rail 222, so as to drive the lifting slide rail 222 to move up and down under the driving of the driving cylinder 21.

[0025] The buffer 24 is fixed on the buffer plate 23, the buffer end faces the direction where the reinforcing plate 13 is located, and is in the same straight line with the reinforcing plate 13, so that when the buffer plate 23 is lowered to the lowest point of the set stroke, the buffer 24 will touch the reinforcing plate 13, realizing the limitation of the lifting height and playing a buffering role for the lifting device and protecting the cylinder.

[0026] The connecting structure 30 includes two fixed connecting blocks 31 arranged at the ends of the lifting slide rail 222 respectively, a cylinder connecting plate 32 connected to the two fixed connecting blocks 31, and two connecting branch plates 33 fixed perpendicularly on the cylinder connecting plate 32.

[0027] The fixed connecting block 31 is fixed on the other end of the lifting slide rail 222 away from the buffer plate 23, so as to play a connecting and fixing role.

[0028] The cylinder connecting plate 32 is fixedly connected with the two fixed connecting blocks 31 through fasteners, and the plate surface of the cylinder connecting plate 32 is perpendicular to the extension direction of the lifting slide rail 222, so as to serve as a base plate for fixing the displacement assembly 40 and the material taking clamp jaw 50.

The displacement slide rail 411 is perpendicular to the extension direction of the lifting slide rail 222, and the two displacement slide rails 411 arranged on the two connecting plates 33 are parallel to each other, so as to drive the material taking gripper 50 to displace horizontally.

[0032] The displacement connecting plate 42 is a rectangular plate fixed on the displacement slide block 412, and is parallel to the connecting plate 33, so as to connect the driving structure and the material taking gripper 50.

[0036] The adjusting plate 46 is a rectangular plate, which is used to connect the driving end of the slide table cylinder 45 and the cylinder connecting plate 32.

[0037] It is conceived that when the slide table cylinder 45 moves, since the driving end is fixedly connected with the cylinder connecting plate 32, the main body part connected with the displacement slide block 412 will be driven to reciprocate along the displacement slide rail 411, so as to realize the displacement of the material taking gripper 50 fixed on the gripper fixing plate 43.

[0038] The material taking gripper 50 comprises a gripper support plate 51 fixed perpendicularly to the gripper fixing plate 43, and a gripper 52 fixed to the gripper support plate 51.
