Description

An automatic sewing device for packing scale

【Technical field】

The invention relates to the technical field of weighing tools, in particular to an automatic sewing device for a packaging scale. the

【Background technique】

After the weighing is completed, the existing electronic packaging scale needs to manually sew the opening of the bag containing the finished product with a specified amount. The work efficiency is low and the labor cost is also high. Completing the sewing of the filling bag improves the degree of automation. However, when the bag falls from the electronic scale, the shape of the opening of the bag is not regular, so it needs to be sorted manually, and the production efficiency is low. When different products are packed or the height of the bag is different, the sealing line of the bag will be different in height and skewed, which will affect the aesthetic effect of the outer packaging of the product, and its production range is narrow. the

【Content of invention】

The purpose of the present invention is to solve the problems in the prior art, and propose an automatic sewing device for a packaging scale, which can not only improve work efficiency, but also expand the processing range and ensure the packaging effect. the

To achieve the above object, the present invention proposes a kind of automatic sewing device of packing scale, comprises control box, drive system, conveyer belt and sewing device, and drive system drives and connects described conveyer belt and sewing device, and control box is connected with drive system , the conveyor belt is horizontally arranged on the ground, a pocket finishing device is arranged above the conveyor belt, the sewing machine is fixed on the pocket finishing device, a pair of fixing frames are arranged on both sides of the conveyor belt, and the fixing frame A chute is arranged on the top of the bag, and a movable block that can move along the chute is arranged in the fixed frame. The pocket finishing device is fixed on the movable block, and the bottom of the movable block is connected with a telescopic mechanism. the

As a preference, the pocket sorting device includes a supporting piece and a clamp fixed side by side above the conveyor belt, and a distance is set between the supporting piece and the clamping piece, and when the packaging bag containing the material is transported on the conveyor belt, the Between the supporting piece and the clamping piece, the opening of the packaging bag is limited by the supporting piece and the clamping piece, making it smooth and flat, which is convenient for the sewing machine to work, saves the manual finishing process, and improves production efficiency. the

As a preference, the distance between the supporting piece and the clip gradually decreases from the conveying direction of the conveyor belt. When the packaging bag containing the material is transported on the conveyor belt, it enters between the supporting piece and the clipping piece. The distance between the clips is gradually reduced, and the support and clips arrange and flatten the opening of the packaging bag, making it smooth and flat, eliminating the manual finishing process, improving production efficiency, and improving the aesthetics of the bag mouth. the

Preferably, the telescopic mechanism includes a piston rod and a hydraulic cylinder, the piston rod is connected to the movable block, the hydraulic cylinder is connected to the control box, and the control box controls the hydraulic cylinder to suck and discharge hydraulic oil to control the expansion and contraction of the piston rod, thereby controlling The lifting of the movable block in the vertical direction adjusts the height of the sewing device and the pocket finishing device to correspond to the opening of the packaging bag. the

Beneficial effects of the present invention: the present invention transports the weighed packaging bag to the sewing device by the conveyor belt to complete the sewing of the bag mouth, and installs a movable block that can move up and down in the fixed frame, so that the distance from the sewing device to the conveyor belt Adjustable, so as to adjust the height of the sewing mouth of the material bag, so that the working range of the present invention is wider. Before the sewing process, the pocket mouth finishing device is used to flatten and tidy the pocket mouth, so as to ensure that the sewing machine works smoothly during sewing, and the sewing effect is improved. Compared with the prior art, the present invention has the advantages of simple structure, high working efficiency, good packaging effect and wide working range. the

The features and advantages of the present invention will be described in detail with reference to the accompanying drawings. the
