Description

Technical Field

[0001] The invention relates to a cement bag mouth corner folding device, belonging to the technical field of cement bag mouth folding equipment. Background Art

[0002] Generally, when cement bags are made and processed, the bag mouth is first stretched open, and then one side of the bag corner is folded inward to form an inward folded corner mouth, which is convenient for filling cement in subsequent operations, and the reserved part of the cement bag mouth must be folded into the cement bag. For this reason, a Chinese patent document with publication number CN108162497A discloses a cement bag folding device, which sucks the bag mouth of the cement bag by a suction cup and lifts it upward to open the bag mouth of the cement bag, and the cylinder B drives the rack B to move, and the rack B drives the transmission gear B to rotate, and the transmission gear B drives the rotating shaft to rotate, and the rotating shaft drives the bag opening plate to rotate, so that the bag opening plate extends into the bag mouth of the cement bag, and the bag opening power source drives the bag opening plate to open and stretch the bag mouth, and the cylinder A drives the rack A to move, and the rack A drives the transmission gear A to rotate, and the transmission gear A drives the folding plate to move toward the bag mouth along the slide rail through the transmission belt, and folds one side of the bag corner inward, so that the folding of multiple cement bags can be completed. However, before folding the cement bag, the upper and lower folded edges at the bag opening of the cement bag need to be pushed into the bag first. Since the bag opening plate enters the cement bag by rotating 90 degrees, the sharp corners of the bag opening plate can easily pierce the upper or lower folded edges of the cement bag during the rotation process, causing the cement bag to tilt or even cause the cement bag to detach from the suction cup, ultimately resulting in folding failure.

Through holes A are processed on the folding positioning plate A20 at positions corresponding to the plurality of bag suction assemblies. When in use, the bag suction assembly on the mounting plate A16 is used to suck the upper surface of the bag opening of the cement bag. The folding positioning plate A20 is used to position the upper folding edge of the cement bag, which helps to fold the upper folding edge of the cement bag into the bag flush. After the corners are folded, the folding positioning plate A20 moves down to close the bag opening. Both the multi-rod cylinder A18 and the multi-rod cylinder B19 use double-rod cylinders, which are prior art and will not be described in detail here.

[0030] The lower suction bag component 9 includes a mounting plate B22 and a folding positioning plate B25. The mounting plate B22 is connected to the frame 1 through a multi-rod cylinder C23. A plurality of suction bag assemblies are installed side by side on the mounting plate B22. The folding positioning plate B25 is located directly above the mounting plate B22 and is connected to the frame 1 through a multi-rod cylinder D24.

After the corners are folded, the folding positioning plate B25 moves up to close the bag opening. Both the multi-rod cylinder C23 and the multi-rod cylinder D24 use double-rod cylinders, which are prior art and will not be described in detail here.

[0031] The suction bag assembly includes a screw 17 and a suction cup 21 mounted at one end of the screw 17, and a through hole C is coaxially processed on the screw 17. When in use, the screw 17 is fixed on the mounting plate A16 or the mounting plate B22 through two nuts, and the end of the screw 17 away from the suction cup 21 is connected to the vacuum pump through an air pipe.

[0032] A plurality of bag suction assemblies are distributed in an L-shape on the mounting plate A16 or the mounting plate B22. The bag suction assemblies suck the folded corners and the positions near the folded edges on the cement bag to open the bag opening.

[0033] The angled assembly comprises a support block 5, a cylinder A2 and an angled plate 3, wherein the support block 5 is mounted on a bottom plate 11, a guide rail A6 is mounted on the top of the support block 5, the angled plate 3 is slidably connected to the guide rail A6 via a connecting plate 4, and the cylinder A2 is mounted on the support block 5 and connected to the connecting plate 4. When in use, the cylinder A2 drives the angled plate 3 to perform linear motion along the length direction of the guide rail A6, and the guide rail A6 is perpendicular to the guide rail B15.

[0034] The translation driving member 13 is a cylinder B.

[0035] The opening and closing driving member 27 is a thin air gripper.

[0036] The folding bag opening plate 10 is in the shape of an equilateral triangle.

[0037] The angle between the hypotenuse of the hemming bag opening plate 10 and the guide rail B15 is 45 degrees. When the hemming bag opening plate 10 is inserted into the cement bag, its hypotenuse is always kept parallel to the upper and lower hemming edges of the cement bag, effectively preventing the hemming bag opening plate 10 from piercing the upper or lower hemming edges of the cement bag when it contacts the upper or lower hemming edges.

[0038] The working principle or working process of the cement bag mouth corner folding device of the present invention is as follows:

[0039] (1) The cement bag is conveyed along the conveying path and stops at the position of the folding and opening bag assembly.

[0040] (2) The multi-rod cylinder A18 drives the mounting plate A16 to move downward until the suction cup 21 on the mounting plate A16 sucks the upper surface of the cement bag opening, and at the same time, the multi-rod cylinder B19 drives the folding positioning plate A20 to move upward to an appropriate position; the multi-rod cylinder C23 drives the mounting plate B22 to move upward until the suction cup 21 on the mounting plate B22 sucks the lower surface of the cement bag opening, and at the same time, the multi-rod cylinder D24 drives the folding positioning plate B25 to move downward to an appropriate position.

[0041] (3) The multi-rod cylinder A18 drives the mounting plate A16 to move upward until the upper surface of the cement bag opening moves up to the folding positioning plate A20, and the multi-rod cylinder C23 drives the mounting plate B22 to move downward until the lower surface of the cement bag opening moves down to the folding positioning plate B25, and the cement bag opening is opened.

[0042] (4) The cylinder B drives the base 26, the opening and closing driving member 27 and the folding bag opening plate 10 to move along the length direction of the guide rail B15. The folding bag opening plate 10 extends into the cement bag and pushes the upper folding edge and the lower folding edge of the cement bag into the bag during the extension process. Then, the opening and closing driving member 27 drives the two folding bag opening plates 10 to open, so that the upper folding edge and the lower folding edge are respectively attached to the upper and lower inner surfaces of the cement bag, and the bag mouth is stretched open.

[0043] (5) The cylinder A2 drives the folding plate 3 to move along the length direction of the guide rail A6, folding the bag corner on one side of the cement bag inward.

[0044] (6) The suction cup releases the upper and lower surfaces of the cement bag, the multi-rod cylinder B19 drives the folding positioning plate A20 to move downward, and the multi-rod cylinder D24 drives the folding positioning plate B25 to move upward. At the same time, the two folding bag opening plates 10 move toward the middle under the drive of the opening and closing drive member 27.

[0045] (7) The two folding edge opening plates 10 are reset under the drive of the cylinder B, and the folding angle plate 3 is reset under the drive of the cylinder A2, thus completing the folding of the edges and corners of the cement bag.
