Packaging bag receiving and conveying device and method

Abstract

The invention relates to the field of packaging equipment, in particular to a packaging bag receiving and conveying device and method and material filling and bagging equipment. The device comprises areceiving rack, and a bag collision mechanism and a conveying mechanism which are fixed on the receiving rack, wherein the bag collision mechanism is located below the output end of a discharging device; the output end of the bag collision mechanism makes contact with the bottom of a packaging bag; the conveying mechanism makes contact with the outer side and an inlet of the filled packaging bag;the input end of the conveying mechanism is connected with the output end of the discharging device; and the output end of the conveying mechanism is connected with the input end of a sealing device.The device is provided with the bag collision mechanism, so that the void ratio of granules in the packaging bag is reduced, and the packaging quality of materials is improved.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a packaging bag receiving and conveying device and method, and material filling and bagging equipment. Background technique [0002] Material filling and bagging equipment is a type of machine that packs materials to protect materials and facilitate transportation. It is mainly suitable for automatic quantitative packaging of materials in rice, food, sugar, chemical and other industries. Material filling and bagging equipment mainly includes: packaging bag feeding, packaging bag opening, material filling, packaging bag conveying and packaging bag sealing and other processes during work. The quality of the packaging process is directly related to the sealing quality of the packaging bag, the accuracy of the filling weight of the material and the compactness of the material in the packaging bag. Therefore, for material packaging, the quality of the packaging equipment used is p...

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When feeding the packaging bag, first use the suction bag mechanism to contact the upper surface of the middle part of the packaging bag to absorb it, and then the driving mechanism drives the suction bag mechanism to move to the delivery bag mechanism to transport the packaging bag to The next station; while the texture of the packaging bag is soft, the edge of the soft packaging bag will bend and sag under the action of gravity after the suction bag mechanism absorbs the middle part of the packaging bag; when the suction bag mechanism loosens the suction bag When the bag is opened and dropped to the conveying bag mechanism, the bent and drooping bag edge will be pressed against the bottom of the bag as the bag falls; resulting in edge wrinkles when the bag is output to the next station, affecting the quality of the bag on the bag

2. When the packaging bag is stretched and conveyed, the bag opening mechanism first stretches the packaging bag, and then flips the air claw hand in the gripping mechanism to grip the stretched packaging bag; at the same time flips the bag holding cylinder in the gripping mechanism Drive the two expansion plates to continue to expand the upper and lower sides of the inner side of the packaging bag, and finally the flipping and gripping mechanism drives the opened packaging bag to rotate to the filling station to complete the packaging bag stretching and conveying process; while the air in the flipping and gripping mechanism When the gripper grips the packaging bag, the cylinder directly drives the gripper to grip the packaging bag; but the manufacturing precision of the cylinder is low and the cylinder shaft and the cylinder wall are easy to wear, and the cylinder shaft and the cylinder wall will be worn due to frequent gripping of the packaging bag. A larger gap is generated; thereby causing the cylinder shaft to shake relative to the cylinder wall when driving the jaws to move, causing the jaws to be unable to accurately grip the packaging bag; at the same time, when the packaging bag is stretched in the flipping and gripping mechanism, it is The two bag-supporting cylinders respectively drive their respective bag-supporting plates to rotate up and down to open the packaging bag; and this method of opening requires two bag-supporting cylinders to work separately, resulting in a large number of bag-supporting cylinders and increasing the complexity of the equipment

3. When filling the packaging bag, the bag grabbing mechanism first grasps the opened packaging bag; then fills the material into the opened packaging bag along the blanking chute, and the bag grabbing mechanism grabs the filled packaging bag The filling process of the packaging bag is completed by releasing the material directly; the packaging bag is in the stretched state when the bag grabbing mechanism grasps the packaging bag tightly, and the packaging bag is also in the stretched state when the bag grabbing mechanism loosens the filled packaging bag and falls; When the bottom of the filled packaging bag is in contact with the receiving and conveying device, the bottom of the packaging bag will be subject to a certain impact, and the material filled inside the packaging bag will be scattered along the opening of the packaging bag after being impacted, resulting in the need for refilling, thus Reduced bag filling efficiency

4. When receiving and conveying the filled packaging bag, the unloading device will drop the material of the set weight into the packaging bag, and then the receiving mechanism located under the packaging bag will directly receive the filled packaging bag and transport it to the sealing device Complete the packaging bag receiving and conveying process; and the material itself has a certain shape, and the materials will support each other when they fall into the packaging bag; when the receiving mechanism directly receives the filled packaging bag, the mutually supported materials in the packaging bag have a large Void ratio; resulting in an increase in the volume of the packaging bag occupied by materials of the same weight, and the material is loose in the packaging bag, reducing the packaging quality of the material
