Description

Technical Field

[0001] The invention discloses an automatic roll-changing device for ground film, belonging to the technical field of film production machinery. Background Art

[0002] With the continuous development of agriculture, the utilization rate of ground film has increased year by year. The ground film is rolled onto a reel through an automatic film rolling machine. The weight of the reel is relatively light. In order to achieve a better film rolling effect, the reel is usually loaded onto an automatic pipe extraction device through a loading device, and the reel is placed into the reel. The reel with the reel is then placed onto the automatic film rolling machine through the loading device. The rolled ground film reel and the reel are then put back onto the automatic pipe extraction device through the loading device. In order to facilitate the dropping of the film-covered reel, support cylinders are set at both ends of the reel, and the reel passes through the support cylinder and the reel. When the film-covered reel and the support cylinder are transported back to the automatic pipe extraction device, the reel is pulled out and the reel can fall.

[0003] The loading device is usually equipped with three manipulators. The manipulator in the middle clamps the reel and places it on the automatic loading device. After the reel is placed, the manipulators at both ends clamp the supporting tubes at both ends and place the supporting tubes, reel and reel on the automatic film rolling machine for coating. After coating, the reel is transported back to the automatic pipe extraction device. In the prior art, the three manipulators are driven by the same drive device to perform reciprocating motion. There is a certain distance between the automatic pipe extraction device and the automatic film rolling machine. The reciprocating motion of the clamping between the two does not require the manipulator in the middle. The manipulator in the middle moves with the manipulators on both sides. Not only is the structure complicated and wasteful, but when the manipulators on both sides need to be repaired, the manipulators on both sides are generally stopped in a relatively empty area in the middle. However, the manipulator in the middle will form a certain obstruction, making maintenance inconvenient. Utility Model Content

[0043] Working process:

[0044] The roll falls onto the push rod 401 through the loading plate 403, and the pushing motor 404 drives the push rod 401 to move upward to the first mechanical claw 202. During the upward movement, the angle between the push rod 401 and the upper shielding part clamps the roll upward, and the lower shielding part blocks the subsequent rolls that roll down. After the first mechanical claw 202 grabs the roll on the push rod 401, the pushing motor 404 drives the push rod 401 back to its original position, and the subsequent rolls continue to roll onto the push rod 401, waiting for the lower side to move upward.

[0045] After the first mechanical claw 202 grabs the reel, the first horizontal motor 5 drives the first mechanical claw 202 to move toward the automatic pipe extraction device, and stops when it moves above the automatic pipe extraction device. The first lifting motor 6 drives the first mechanical claw 202 downward to place the reel on the automatic pipe extraction device. The first lifting motor 6 drives the first mechanical claw 202 to retract, and the first horizontal motor 5 drives the first mechanical claw 202 back to its original position.

[0046] After the automatic pipe extraction device sends the roller into the reel and the support tubes at both ends, the second mechanical claw 302 is driven by the second lifting motor 9 to descend and grab the support tubes at both ends, and the combined tube and the reel are translated to the automatic film winding machine through the synchronous belt 7 for coating. After coating, the second mechanical claw 302 sends the coated combined tube and reel back to the automatic pipe extraction device, and the automatic pipe extraction device pulls out the reel, and the coated reel falls down to proceed to the next step.
