Problems solved by technology

[0003] After the valve port woven bag is processed and formed, it needs to be cornered at one of the end corners to form a valve port structure; the existing technology usually manually folds the valve port, and this method leads to the processing efficiency of the valve port woven bag. lower
[0004] Some of the existing technologies for automatically folding corners of woven bags at the valve port mostly use vacuum suction cups to open the bags, and then use inserting plates, paddles, etc. to fold to complete the cornering work of the valve ports; The automatic valve port knuckle operation, but there are still problems such as huge processing equipment and relatively complicated mechanical structure.

Embodiment 1

[0038] Such as Figure 1-3 As shown, a valve opening woven bag knuckle device includes: a working surface 1 and a knuckle mechanism.

[0039] The working surface 1 is a horizontal working surface used for conveying the woven bag a and for performing valve knuckle operation on the woven bag a.

[0040] The knuckle mechanism is arranged on one side of the working surface 1 along the conveying direction of the woven bag a, which includes:

[0041] Such as figure 2 As shown, the guide plate 21 arranged on the working surface 1 for gradually raising the mouth of the woven bag a, the guide plate 21 extends from the side line c of the working surface 1 to connect with the right adsorption plate 22;

[0042] Such as figure 2 As shown, the right suction plate 22 that is perpendicular to and arranged on the working surface 1 and is connected with the guide plate 21, and the left suction plate 23 that is arranged corresponding to the right suction plate 22, the left suction plate 23...

Embodiment 2

[0055] The present invention also provides a method for kneading a woven bag at a valve port, using the device for kneading a woven bag at a valve port as described in Embodiment 1, and the method for kneading a woven bag at a valve port includes the following steps:

[0056] ①The woven bag is moved along the working surface 1 by the conveying mechanism. When it comes into contact with the guide plate 21, the bag opening gradually moves upwards under the action of the guide plate 21. When the woven bag moves to the end of the guide plate 21, the opening of the woven bag One end is folded and erected perpendicular to the working surface 1 along with the guide plate 21;

[0057] ② One end of the mouth of the woven bag folded and erected perpendicular to the working surface 1 is introduced into the opening part b between the left and right adsorption plates along the opening between the baffle plate 25 and the guide plate 21;

[0058] ③The vacuum suction holes set on the left and...

Abstract

The invention relates to machining equipment and methods for woven bag valve ports, in particular to a corner folding device and method for a valve port woven bag. The corner folding device for the valve port woven bag includes a worktable and a corner folding mechanism. The corner folding action of the valve port woven bag can be rapidly and effectively completed by means of a simple mechanical structure and relatively-simple operation steps.

Description

technical field [0001] The invention relates to a processing device and method for a woven bag valve port, in particular to a valve port woven bag corner-folding device and a corner-folding method. Background technique [0002] Woven bag is a kind of packaging bag formed by drawing and weaving chemical raw materials such as polyethylene and polypropylene. It is widely used in the packaging and transportation of cement, fertilizer and chemical products. [0003] After the valve port woven bag is processed and formed, it needs to be cornered at one of the end corners to form a valve port structure; the existing technology usually manually folds the valve port, and this method leads to the processing efficiency of the valve port woven bag. lower. [0004] Some of the existing technologies for automatically folding corners of woven bags at the valve port mostly use vacuum suction cups to open the bags, and then use inserting plates, paddles, etc. to fold to complete the corneri...
