Description

Technical Field

[0001] The utility model relates to the technical field of cement bag inserting machines, in particular to a bag tail sucking mechanism for a bag inserting machine. Background Technique

[0002] With the popularization of intelligent factories, it has become a current trend for cement plants to use bag inserting machines instead of manual bag inserting. The packaging bags used on cement packaging machines mainly include bottom-sealed valve bags, stitched valve bags, and bottom-sewn bags. When in use, the upper port of the packaging bag is usually opened, and then the bag mouth is inserted into the feeding pipe of the cement packaging machine for filling.

[0003] The existing patent CN215591150U discloses a swing arm type bottom-sealed bag inserting machine, which includes a frame and a swing arm mechanism; a bag supply mechanism, a bag feeding mechanism, a lifting mechanism, a bag aligning mechanism, a bag supporting mechanism, and a bag sucking mechanism are installed on the frame; the bag sucking mechanism is located above the lifting mechanism, sucks the packaging bag on the lifting mechanism, and places the packaging bag from a horizontal state to a vertical state; the bag sucking mechanism includes a front bag sucking member and a rear bag sucking member. The front suction cup of the front bag sucking member sucks the front part of the packaging bag, and then the front bag sucking member moves back to the initial position with the grabbed packaging bag, and opens the bag mouth of the packaging bag to wait for the bag clamping manipulator to clamp it. At the same time, the rear suction cup of the rear bag sucking member descends to press the rear part of the packaging bag to be grabbed, and at the same time, the suction cup sucks the packaging bag. When the front bag sucking mechanism sucks up the packaging bag and the bag clamping manipulator grabs the packaging bag, the rear bag sucking cylinder drives the suction cup bracket to rise, driving the rear suction cup back to the waiting position together.

[0004] Although the above structure can replace manual bag inserting, it is found in actual application that the rear bag sucking member is fixedly installed on the bag inserting machine frame, and the position where the rear suction cup of the rear bag sucking member descends to suck the packaging bag is fixed. When it is necessary to replace packaging bags of other specifications and sizes, the position of the rear bag sucking member cannot be adjusted, and there may be a situation where the rear suction cup sucks the bag too far forward or fails to suck the packaging bag.

[0005] Based on the above problems, a bag tail sucking mechanism for a bag inserting machine is proposed. Content of the Utility Model

Detailed implementation mode

[0024] To fully understand the purpose, features and effects of the present utility model, through the following specific implementation modes, as Figures 1 to 5 shown, the present utility model is described in detail, but the present utility model is not limited thereto.

[0025] A bag tail suction bag mechanism of a bag inserting machine is composed of a bag aligning unit 3, a bag tail suction bag unit 4 and a mounting bracket 1. The mounting bracket 1 is fixedly connected to the frame of the bag inserting machine. An adjusting unit 5 is arranged on the mounting bracket 1. The bag aligning unit 3 and the bag tail suction bag unit 4 are respectively connected to the adjusting unit 5. The positions of the bag aligning unit 3 and the bag tail suction bag unit 4 are adjusted through the adjusting unit 5 to meet the suction of packaging bags of different specifications and sizes.

[0026] In the embodiment, the adjusting unit 5 is composed of a fixed seat 501 and sliding components arranged on both sides of the fixed seat 501. The fixed seat 501 slides relative to the mounting bracket 1 through the sliding components. The sliding components are composed of two guide rods 2, sliding seats and pulleys 504. The two guide rods 2 are respectively arranged symmetrically on both sides of the mounting bracket 1. Sliding seats are respectively arranged on both sides of the fixed seat 501. The sliding seats move along the guide rods 2 through the pulleys 504 mounted thereon to realize the adjustment of the position of the fixed seat 501.

[0027] The sliding seats on each side are respectively composed of an upper sliding seat 502 and a lower sliding seat 503. Pulley 504 is installed on both the upper sliding seat 502 and the lower sliding seat 503. The pulley 504 of the upper sliding seat 502 is placed above the guide rod 2, and the pulley 504 of the lower sliding seat 503 is placed below the guide rod 2. The fixed seat 501 realizes the position adjustment of the fixed seat 501 through the relative sliding of the pulleys 504 of the upper and lower sliding seats 503 on both sides and the guide rod 2.

[0028] A positioning unit 9 is also installed on the lower sliding seat 503 on one side of the fixed seat 501. The positioning unit 9 is composed of a clamping member 902 and a connecting member 901. One end of the connecting member 901 is fixedly connected to the lower sliding seat 503 through a bolt assembly, and a clamping member 902 is installed at the other end of the connecting member 901. The clamping member 902 is sleeved on the guide rod 2 on its side and is locked by a locking bolt, fixing the fixed seat 501 on the guide rod 2. Unscrew the locking bolt to release the clamping of the clamping member 902 on the guide rod 2, and push the fixed seat 501 along the guide rod 2 to adjust the position of the fixed seat 501, achieving the effect of adjusting the positions of the bag tail suction bag unit 4 and the bag righting unit 3.

[0029] In this embodiment, covers 6 are respectively arranged at the positions corresponding to the pulleys 504 on both sides of the fixed seat 501. The covers 6 are buckled outside the pulleys 504, and the top of the cover 6 is bolted to the upper sliding seat 502 on its side; an indicating arrow 7 is arranged outside one of the covers 6, and a scale 8 is arranged on the mounting rack 1 at the position corresponding to the indicating arrow 7. When adjusting the position of the fixed seat 501, the position of the indicating arrow 7 and the scale 8 can be used as a basis.

[0030] The bag righting unit 3 is composed of a bag righting cylinder 301 and a bag righting plate 304. The output end of the bag righting cylinder 301 is connected to the bag righting plate 304 through a bag righting bracket 303, and the bag righting plate 304 is vertically arranged. The bag righting cylinder 301 is connected to the fixed seat 501 through a bag righting base 302.

[0031] The bag tail suction bag unit 4 is composed of a suction bag cylinder 401, a suction cup 403 bracket 402, and a suction cup 403. The suction bag cylinder 401 is fixedly connected to the upper end of the fixed seat 501 through a bag tail suction bag base 404. The lower end of the output end of the suction bag cylinder 401 is fixedly connected to the suction cup 403. The suction cup 403 is arranged on the suction cup 403 bracket 402, and the suction cup 403 is used to suck the tail of the packaging bag.

[0032] When this embodiment is applied, loosen the locking bolt to release the clamping of the clamping member 902 on the guide rod 2, and then determine the displacement of the suction cup 403 according to the specification size of the packaging bag. Push the fixed seat 501. When the indicating arrow 7 moves to the corresponding scale, use the locking bolt to lock the clamping member 902 and the guide rod 2, that is, stably connect the fixed seat 501 and its overall structure on it to the mounting rack 1.

[0033] In the utility model, the front bag unit 3 and the bag tail sucking bag unit 4 are installed on the fixed seat 501, and the fixed seat 501 is slidably connected with the mounting frame 1 through the adjusting unit 5, so that the position of the front bag plate 304 and the position of the bag tail sucking bag suction cup 403 of the device can be adjusted according to the specification size of the packaging bag, avoiding the situation that the suction cup 403 cannot suck the packaging bag or the bag sucking position is too forward, enabling the bag inserting machine to accurately suck the tail of the packaging bag and ensuring the stable operation of the bag inserting machine.

[0034] Finally, it should be noted that the above-listed are only the preferred embodiments of the utility model. Of course, those skilled in the art can make changes and modifications to the utility model. If these modifications and variations fall within the scope of the claims of the utility model and its equivalent technologies, they should be considered within the protection scope of the utility model.
