Description

Technical Field

[0001] This utility model relates to the technical field of automatic cement bag inserting, and more specifically to a bag-taking and pressing device for an automatic cement bag inserting machine. Background Technology

[0002] Currently, the automatic cement bag inserting machine has a complex bag-taking and pressing structure, and the parts are prone to wear. Repairing and replacing parts leads to a decrease in production efficiency. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model proposes a coaxial double cam driven bag-taking and pressing device for an automatic cement bag inserting machine. The structure is simple and compact, the service life of the parts is long, the downtime is reduced, and the production efficiency is improved.

[0004] The technical solution of this utility model is: a bag-taking and pressing device for an automatic cement bag inserting machine, including a frame and a servo motor, a double cam mechanism, a pressing mechanism and a bag-taking mechanism mounted on the frame. The servo motor drives the double cam mechanism through a synchronous belt. The double cam mechanism is hinged to the pressing mechanism through a buffer cylinder and to the bag-taking mechanism through a connecting rod, so as to realize the synchronous linkage between the bag-taking mechanism and the pressing mechanism.

[0005] Preferably, the servo motor on the upper part of the frame drives the double cam mechanism via a synchronous belt.

[0006] Preferably, the two cams in the double cam mechanism are arranged coaxially.

[0007] Preferably, the dual-cam mechanism drives both the bag-taking mechanism and the pressing mechanism simultaneously.

[0008] Preferably, the two ends of the buffer cylinder are hinged to the clamping swing arm and the double cam mechanism of the clamping mechanism, respectively, and the buffer cylinder is used to reduce the motion inertia of the clamping mechanism.

[0009] Preferably, the two ends of the connecting rod are hinged to the bag-taking swing arm of the bag-taking mechanism and the double cam mechanism, respectively.

[0010] Preferably, the bag-collecting mechanism is equipped with a guide rod, which ensures that the suction cup is always perpendicular to the cement packaging bag to be collected. Attached Figure Description

[0016] like Figures 1 to 5 As shown, this embodiment provides a bag-taking and pressing device for an automatic cement bagging machine, including a frame 1 and a servo motor 2, a double cam mechanism 10, a pressing mechanism 4, and a bag-taking mechanism 3 mounted on the frame 1. The servo motor 2 drives the double cam mechanism 10 through a synchronous belt 9. The double cam mechanism 10 is hinged to the pressing mechanism 4 through a buffer cylinder 21 and to the bag-taking mechanism 3 through a connecting rod 16, thereby realizing the synchronous linkage between the bag-taking mechanism 3 and the pressing mechanism 4.

[0017] In this example, cams A11 and B12 in the double cam mechanism 10 are arranged at both ends of the rotating shaft A13, which has a simple structure and high transmission efficiency.

[0018] The servo motor 2 is fixed to the upper part of the frame 1 and drives the double cam mechanism 10 through the synchronous belt 9.

[0019] The suction cup 14 is mounted on the suction cup bracket 15 in the bag-retrieving mechanism 3 and is hinged to the guide rod 6 and fixed to the bag-retrieving swing arm 7. The two ends of the connecting rod 16 are hinged to the cam A11 and the bag-retrieving swing arm 7 respectively, converting the rotational motion of the cam A11 into the reciprocating motion of the bag-retrieving mechanism.

[0020] In the pressing mechanism 4, the bag pressing wheel bracket 18 and the pressing swing arm 17 are fixed on the rotating shaft B20, and the bag pressing wheel 8 is mounted on the bag pressing wheel bracket 19. The buffer cylinder 21 is hinged at both ends to the cam B12 and the pressing swing arm 17 respectively, converting the rotational motion of the cam B12 into the reciprocating motion of the pressing mechanism.

[0021] The working process of the bag-removing and pressing device of the automatic cement bag inserting machine described in this utility model is as follows:

[0022] The cement packaging bag 18 is placed horizontally below the bag-taking mechanism 3, and the bag-taking mechanism 3 and the pressing mechanism 4 are in their initial positions;

[0023] The servo motor 2 drives the rotating shaft A13 in the double cam mechanism 10 to rotate via the synchronous belt 9, and the cams A11 and B12 fixed at both ends of the rotating shaft A13 rotate accordingly.

[0024] Cam A11 drives the bag-picking arm 7 in the bag-picking mechanism 3 to move downwards via connecting rod 16. Guide rod 6 moves synchronously with bag-picking arm 7, causing suction cup 14 to contact cement packaging bag 18 and adsorb cement packaging bag 18 onto suction cup 14. Cam B12 drives the pressing mechanism 4 via buffer cylinder 21, causing pressing wheel 8 to swing away from drive belt 5. Figure 4 ;

[0025] Servo motor 2 drives the rotating shaft A13 in the double cam mechanism 10 to continue rotating via synchronous belt 9. Cam A11 drives the bag-picking mechanism 3 and the cement packaging bag 18 held by suction cup 14 to rise to the initial position. Simultaneously, cam B12 drives the pressing mechanism 4 back to the initial position, pressing the cement packaging bag 18 tightly against the drive belt 5. Figure 5 .
