Problems solved by technology

[0002] The woven bag making equipment is relatively mature equipment, but since the woven bag is generally cut by thermal cutting, the cut woven bag will have different degrees of bonding at its opening end, which is not conducive to automatic packaging of materials with woven bags. Open the mouth of the woven bag. Therefore, it is generally necessary to manually open the bonded bag mouth during the bag making process or before using the woven bag to pack the material, which is inconvenient to use.
The existing plan for rubbing the mouth of eagerly cut woven bags is basically to rub the mouth in the warp direction, that is, to rub the mouth with a mouth rubbing device along the warp direction of the woven bag. However, when the adhesion of the mouth of the woven bag is serious, the woven bag will Adhesive mouth can move with the mouth rubbing part of the mouth rubbing device, making it impossible to rub open

Embodiment 1

[0022] Two strip-shaped rubbing blocks with a rectangular cross-section are aligned up and down and arranged at a certain distance. The woven bag near the mouth of the woven bag is pressed onto the upper rubbing block, the upper and lower rubbing blocks squeeze the woven bag near the mouth of the woven bag, the upper rubbing block moves along the length of the rubbing block, and the upper layer of the woven bag moves with the upper rubbing block , the lower layer of the woven bag moves with the lower rubbing block, rubs the opening of the woven bag, resets the upper rubbing block to the initial position aligned with the lower rubbing block, moves the lower rubbing block down to the initial position away from the upper rubbing block, and completes a weaving Open the pocket by rubbing.

Embodiment 2

[0024] Two horizontal strip-shaped rubbing blocks with a rectangular cross-section are separated by a certain distance up and down and arranged in a direction perpendicular to the length direction of the rubbing blocks. Between the root rubbing blocks, the upper rubbing block cuts into the direction of the lower rubbing block along the arc in the plane where the two rubbing blocks are located, and moves towards the lower rubbing block until the woven bag near the mouth of the woven bag is pressed by the upper rubbing block. On the lower rubbing block, the upper rubbing block continues to translate, the lower rubbing block is pressed down by the upper rubbing block, and at the same time pushed up by the spring at the lower part of the lower rubbing block, so that the lower rubbing block moves away from the The direction of the upper rubbing block moves back, and the mouth of the woven bag is rubbed open during the continuous translation of the upper rubbing block, and the upper ...

Embodiment 3

[0037] Embodiment 3 of the woven bag mouth rubbing device applying the method described in the present invention (see image 3 ):

[0038] The mouth rubbing device of the woven bag of this embodiment comprises a frame 1, a rubbing cylinder 21, a movable connector 220 of the rubbing cylinder, a swing arm 410, an upper rubbing pad 51, an upper rubbing block 52, a lower rubbing pad 61, and a lower rubbing block 62, compression guide shaft 72, compression guide bushing 73 and spring 9;

[0039] Described frame 1 is a frame structure part; Described rubbing cylinder 21 is simultaneously as rubbing driving part and compressing driving part (do not get rid of the mechanism that adopts motor, leading screw, nut mechanism etc. to output as linear displacement, or motor, deceleration machine output rotation mechanism), the swing arm 410 is used as a movable part of the rubbing guide part, and the swing arm 410 is hinged to the rotating shaft on the frame 1 as a fixed part of the rubbin...

Abstract

The invention relates to the technology of forming coiled woven bag barrel materials into woven bags, in particular to a method for zonally twisting an opening of a woven bag and a woven bag opening twisting device applying the method. According to the method disclosed by the invention, two stripped twisting blocks are used nearby a woven bag opening to be subjected to opening twisting to squeeze and hold the woven bag, wherein cross section of each twisting block is rectangular, an edge of the woven bag opening is parallel to a length direction of the twisting blocks, and the two twisting blocks move relative to each other along the length direction to zonally twist adhered opening of the woven bag and separate the adhered opening. The woven bag opening twisting device applies the method for zonally twisting the opening of thewoven bag to separate the opening of the woven bag, and comprises a machine frame, a twisting driving component, a twisting guiding component, an upper opening twisting component, a lower opening twisting component, a pressing driving component and a pressing directing component. Melt and adhered woven bag openings can be twisted and separated by applying the method and the device disclosed by the invention during the preparation of woven bags, and automatic opening of the woven bag picked up by packing equipment at a later stage is convenient.

Description

technical field [0001] The invention relates to the technology of making a woven bag from roll-packed woven bag material, in particular to a weft rubbing method for a woven bag and a woven bag rubbing device using the method. The weft rubbing method for a woven bag is applied Two strip-shaped rubbing blocks with a rectangular cross-section squeeze and hold the woven bag near the mouth of the woven bag that needs to be rubbed open. The edge of the woven bag mouth is parallel to the length direction of the rubbing block, and the two rubbing blocks are Relative movement in the direction will rub the bonded mouth of the woven bag along the weft direction of the woven bag; Frame, rubbing driving part, rubbing guide part, upper rubbing mouth part, lower rubbing mouth part, pressing driving part and pressing guiding part, applying the inventive method and device in the woven bag preparation device to make the woven bag can ensure that the melted The mouth of the bonded woven bag is ...
