Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of conveying equipment, especially to a conveying mechanism for conveying special-shaped plastic parts into a plastic fuel tank. BACKGROUND

[0002] In order to meet the national six B emission standard, the plastic fuel tank needs to be installed with a special-shaped plastic part with a convex part at the opening at the top. The convex part of the special-shaped plastic part after installation will pass through the opening at the top of the plastic fuel tank and be placed in the plastic fuel tank. However, during the installation process of the special-shaped plastic part, the special-shaped plastic part cannot directly enter the interior of the plastic fuel tank vertically (centered) through the opening of the plastic fuel tank, and the convex part will interfere with the opening of the plastic fuel tank, as shown in Figure 5 (A is a plastic fuel tank, and B is a special-shaped plastic part). Therefore, different drive units need to be controlled to cooperate (for example, a vertical drive cylinder for vertical driving and a horizontal drive cylinder for horizontal driving) to move the special-shaped plastic part horizontally, and after the convex part of the special-shaped plastic part passes through the opening of the plastic fuel tank in a horizontal state, the special-shaped plastic part is moved back horizontally to make the special-shaped plastic part centered with the opening of the plastic fuel tank again (which is required for installation).

[0003] In the above process, different drive units need to be controlled to cooperate, which not only increases the production cost, but also requires time response for the associated cooperation between different drive units, resulting in low production efficiency and not meeting the production requirements of enterprises.

[0010] The composite transmission module is in sliding connection with the displacement guide sliding groove, and under the cooperation of the lifting driving module and the displacement guide sliding groove, the composite transmission module drives the gripper module to displace along the extension direction of the displacement guide sliding groove in the descending process, so that the special-shaped plastic part gripped by the gripper module avoids the blockage of the plastic fuel tank opening.

[0011] Further, the composite transmission module comprises a fixed connecting piece, a displacement connecting piece and a connecting arm.

[0012] The fixed connecting piece is connected with the lifting connecting assembly.

[0013] One end of the displacement connecting piece is in sliding connection with the fixed connecting piece, and the other end is in sliding connection with the displacement guide sliding groove through the connecting arm.

[0014] The gripper module is connected with the bottom of the displacement connecting piece.

[0017] Further, the bottom of the displacement connecting piece is provided with a circumferential adjusting piece.

[0018] The circumferential adjusting piece is provided with a circumferential adjusting groove extending along the circumferential direction.

[0019] The gripper module is connected with the circumferential adjusting piece through the cooperation of the bolt and the circumferential adjusting groove, and the angle thereof is adjusted.

[0021] The lifting driving cylinder is installed on the cylinder seat.

[0022] The displacement guide sliding groove is arranged on one side of the cylinder seat.

[0023] Further, the cylinder seat is provided with a vertical groove.

[0024] The lifting connecting assembly comprises a lifting installation plate and a connecting seat.

[0025] The lifting installation plate is connected with the lifting driving cylinder, and the back surface thereof is provided with a vertical sliding guide rail, the lifting installation plate is in sliding connection with the cylinder seat through the cooperation of the vertical sliding guide rail and the vertical groove.

[0026] The connecting seat is arranged on the front surface of the lifting installation plate.

[0029] The connecting seat is detachably connected with the lifting mounting plate through the screw and the lifting adjusting groove, and the height of the connecting seat is convenient to adjust.

[0030] Further, the gripper module is a pneumatic clamping jaw.

[0031] Compared with the prior art, the technical scheme has the following principles and advantages:

[0032] When the special-shaped plastic part needs to be installed in the opening on the top of the plastic fuel tank, the gripper module is used to grab the special-shaped plastic part and place it above the opening on the top of the plastic fuel tank and align the opening on the top of the plastic fuel tank; then, the lifting driving module drives the special-shaped plastic part to descend, when the convex part of the special-shaped plastic part almost contacts the opening on the top of the plastic fuel tank, the composite transmission module is displaced under the guidance of the displacement guide sliding groove, so that the convex part of the special-shaped plastic part can avoid the side wall of the opening on the top of the plastic fuel tank when the convex part of the special-shaped plastic part penetrates into the opening on the top of the plastic fuel tank, and interference is avoided (at this time, the special-shaped plastic part is in a misaligned state). When the convex part of the special-shaped plastic part penetrates through the opening on the top of the plastic fuel tank and enters the inside of the plastic fuel tank, the composite transmission module is reversely displaced under the guidance of the displacement guide sliding groove, so that the special-shaped plastic part is again centered with the opening of the plastic fuel tank.

[0033] The technical scheme only needs to control the lifting driving module and the displacement guide sliding groove to cooperate and drive the composite transmission module to perform composite transmission, so that interference between the convex part of the special-shaped plastic part and the opening of the plastic fuel tank during the installation of the special-shaped plastic part is avoided (without the need to control other driving units), which not only can reduce the production cost, but also the associated cooperation of the lifting driving module and the displacement guide sliding groove does not need time response, the production efficiency is higher, and the production requirements of enterprises are met.
