Abstract
Description
Technical Field
[0001] The present application relates to the technical field of valve bag packaging, and in particular to a valve bag tensioning mechanism for a packaging machine. Background Art
[0002] In modern industrial production, the application of automated packaging equipment is becoming more and more extensive, especially for the packaging of powdered and granular materials. Valve bags, commonly known as paste-bottom bags, are an internationally popular packaging bag. They are fed from the valve port at the top or bottom and filled with special filling equipment. After filling the material, the valve bag automatically forms a rectangular parallelepiped. It has the characteristics of efficient filling, neat stacking, firmness and reliability, convenient transportation, and beautiful appearance. Valve bags are widely used due to their sealing and strong load-bearing capacity.
[0003] When a valve bag is used to package powder, the bag opening of the valve bag needs to be placed on the feeding pipe, and then the feeding pipe fills the powder into the interior of the valve bag to complete the material packaging. However, in the existing powder packaging operation, the bag opening of the valve bag is only simply positioned and the bag opening is not sealed. The powder is easy to overflow, which not only causes waste of powder, but also pollutes the working environment, affects the normal breathing of workers, and increases the cleaning burden of workers. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a valve bag tensioning mechanism for a packaging machine, which is capable of tensioning the inner wall of the valve bag opening and sealing the bag opening of the valve bag, effectively preventing powder from overflowing during the filling process and causing waste, and can recover the powder that accidentally overflows, avoiding pollution of the working environment, ensuring the cleanliness of the working environment, and reducing the cleaning burden of workers. It solves the problem that in the existing powder packaging operation, only the bag opening of the valve bag is simply positioned and the bag opening is not sealed, which makes powder easily overflow, not only causing waste of powder, but also polluting the working environment, affecting the normal breathing of workers, and increasing the cleaning burden of workers.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a packaging machine valve bag tensioning mechanism, comprising a packaging machine body, a feeding tube is provided inside the packaging machine body, an air bag is provided on the outer circumferential surface of the feeding tube, the air bag is arranged in a ring shape, an air pipe is fixedly connected to the back of the air bag, the air bag is communicated with the air pipe, a sealing ring is fixedly sleeved on the outer circumferential surface of the air bag, the air bag and the sealing ring are both made of elastic material, an air pump is provided on the end of the air pipe away from the air bag, a suction device is provided on the back of the packaging machine body, suction tubes are equidistantly arranged on both sides of the suction device, two support plates are fixedly connected to the front of the packaging machine body, and the outer circumferential surfaces of the suction tubes are fixedly plugged into the inner parts of the support plates respectively.
[0006] Through the above scheme, since the existing powder packaging operation only performs simple positioning on the bag opening of the valve bag and does not seal the bag opening, the powder is easy to overflow, which not only causes waste of powder, but also pollutes the working environment, affects the normal breathing of workers, and increases the cleaning burden of workers. By arranging an air bag of elastic material on the outside of the feeding tube and an elastic material sealing ring on the outside of the air bag, and using an air pump and an air pipe to control the contraction and expansion of the air bag, the inner wall of the bag opening of the valve bag can be tightened during the powder filling operation, and the bag opening of the valve bag can be sealed, effectively preventing the powder from overflowing during the filling process. By arranging suction equipment and a suction pipe, the powder that accidentally overflows can be recovered, avoiding pollution of the working environment, ensuring the cleanliness of the working construction environment, and reducing the cleaning burden of workers.
[0007] Furthermore, a limiting groove is provided on the outer circumferential surface of the feeding tube, the airbag is sleeved inside the limiting groove, and the airbag is bonded to the inner wall of the limiting groove.
[0008] Through the above solution, the airbag is bonded inside the limiting groove to restrict the airbag, thereby preventing the airbag from easily shifting or falling off from the feeding tube, thereby improving the stability of the airbag during operation.
[0009] Furthermore, the front end of the feeding tube is a tapered structure.
[0010] Through the above solution, the feeding pipe with a conical structure facilitates the installation operation of the valve bag bag mouth, providing convenience for the staff.
[0011] Furthermore, a cylinder is provided above the feeding tube, a pressing plate is fixedly connected to the output end of the cylinder, and a rubber pad is provided at the bottom of the pressing plate.
[0012] Through the above scheme, the bag opening of the valve bag can be positioned by the cylinder-driven pressing piece, so that the bag opening of the valve bag is fixed on the feeding tube, preventing the valve bag from easily moving and falling off during the filling operation, thereby improving the stability of the valve bag filling operation. The rubber pad can not only provide protection for the valve bag and the feeding tube, avoiding damage to the valve bag and the feeding tube during the squeezing and positioning process, but also increase the friction between the pressing piece and the valve bag, further improving the stability of the valve bag.
[0013] Furthermore, a bracket is fixedly connected to the inner wall of the packaging machine body, and the outer circumferential surface of the cylinder is fixedly plugged into the interior of the bracket.
[0014] Through the above solution, the cylinder is installed and fixed by the bracket, and the cylinder is installed above the feeding pipe.
[0015] Furthermore, a slot is provided at the bottom of the feeding tube, and the air pipe is connected to the inside of the slot.
[0016] Through the above solution, the trachea is clamped into the clamping slot, and the trachea can be restricted by the clamping slot to prevent the trachea from being hung arbitrarily.
[0017] Furthermore, the air pipe is a plastic hose, and the suction pipe is a hard metal pipe.
[0018] Through the above solution, the soft air tube has high flexibility, which is convenient for arranging the air tube, while the hard suction tube has high stability.
[0019] Furthermore, a placement groove is provided inside the packaging machine body, and the air pump is located inside the placement groove.
[0020] According to the above solution, the air pump is placed in the placement slot and is placed inside the packaging machine body to avoid occupying external space.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] The valve bag tensioning mechanism of the packaging machine, by arranging an air bag made of elastic material on the outside of a feeding tube and a sealing ring made of elastic material on the outside of the air bag, and using an air pump and an air tube to control the contraction and expansion of the air bag, can tension the inner wall of the bag opening of the valve bag during the powder filling operation, seal the bag opening of the valve bag, and effectively prevent the powder from overflowing during the filling process. By arranging a suction device and a suction tube, the powder that is accidentally overflowed can be recovered to avoid polluting the working environment, ensure the cleanliness of the working construction environment, and reduce the cleaning burden of the workers. This solves the problem that in the existing powder packaging operation, the bag opening of the valve bag is only simply positioned but not sealed, and the powder is easy to overflow, which not only causes waste of powder, but also pollutes the working environment, affects the normal breathing of the workers, and increases the cleaning burden of the workers.

The bag 3 and the sealing ring 13 will shrink immediately, and then the cylinder 7 will be started to drive the pressing piece 8 to rise, and the positioning restriction on the bag mouth of the valve bag will be cancelled. The valve bag can be removed and subsequent sealing operations can be carried out. During the powder filling process, the suction device 14 can be started to suck air through the suction pipe 15 to recover the powder that has accidentally overflowed, further protecting the working environment and reducing the cleaning burden on the workers.
