Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment and relates to a packaging bag flattening conveying device. Background Art

[0002] After the fertilizer bags are filled, they will continue to be transported on the conveyor belt to be sealed and packaged. However, since the bagged fertilizers are filled and sealed vertically, when the bagged fertilizers lie flat on the conveyor line, the fertilizers are unevenly distributed inside the packaging bags, resulting in uneven packaging surfaces, making it difficult to seal the boxes, which greatly reduces the efficiency of subsequent sealing and packaging.

[0003] In practical applications, packaging bags are generally flattened by a bag pressing machine, but the existing bag pressing machines generally only use a roller to flatten the packaging bags. Due to the uneven distribution of goods, the packaging bags are subjected to excessive squeezing force at one time during the flattening process, which can easily cause the packaging bags to get stuck or even break. In addition, the existing bag pressing machines are not convenient for adjusting the height and angle of the bags. Therefore, a packaging bag flattening and conveying device that can reduce the probability of bag damage is needed to solve the above problems. Utility Model Content

A plurality of rotatable rotating rollers 7 are provided in the middle part of the first rotating frame 5. The first rotating frame 5, the rotating rollers 7 and the second rotating frame 6 cooperate with each other to form a secondary flattening structure.

[0026] When in use, first adjust the angle of the flattening frame 4 and the height relative to the conveyor belt 3 to appropriate values, so that the conveyor belt 3 and the first rotating frame 5 and the second rotating frame 6 start to rotate, and the material to be flattened (such as a fertilizer bag) can be placed on the front end of the conveyor belt 3. At this time, the conveyor belt 3 transports the fertilizer bag backwards, and the rotation directions of the first rotating frame 5 and the second rotating frame 6 are the same and opposite to the rotation direction of the conveyor belt 3, so that the fertilizer bag can pass from the lower side of the first rotating frame 5 and the second rotating frame 6. At this time, the first rotating frame 5 can flatten the fertilizer bag for the first time by rotating the roller 7, so that the material in the fertilizer bag can be evenly distributed inside the fertilizer bag, and the second rotating frame 6 can flatten the fertilizer bag for the second time to improve the flattening effect of the fertilizer bag.

[0027] Further, by Figure 1-Figure 4 It is given that, in order to enable the device to adapt to different bag heights for flattening, a plurality of adjusting screws 8 are connected to the upper side of the flattening frame 4 in a front-to-back symmetrical rotation, and an adjusting hole 9 is provided at the upper part of the fixing frame 2 corresponding to the position of each adjusting screw 8. The adjusting hole 9 is a waist-shaped hole, so that each adjusting screw 8 can be adjusted in the front-to-back direction.

[0031] Further, by Figure 1-Figure 4 It is given that, in order to achieve the purpose of flattening the material in the packaging bag, the first rotating frame 5 is internally fixedly connected with a first fixing rod 11 corresponding to the rotating rollers 7 by bolts, and each rotating roller 7 is coaxially rotatably sleeved on the outer side of the corresponding rotating roller 7;

[0032] When in use, the first fixing rod 11 can be used to facilitate installation, maintenance and replacement of the rotating roller 7 .

[0034] When in use, the first pulley 13 and the second pulley 14 are driven to rotate by the rotation of the driving shaft 12, and then the third pulley 15 and the fourth pulley 17 are rotated under the action of the first belt 16 and the second belt 18 respectively, driving the first rotating frame 5 and the second rotating frame 6 to rotate.

[0035] Further, by Figure 1-Figure 4 It is given that a first motor 19 is fixedly connected to the upper side of the flattening frame 4, a driving pulley 20 is fixedly connected to the left side of the first motor 19, a driven pulley 21 corresponding to the driving pulley 20 is coaxially fixedly connected to the middle part of the driving shaft 12, and the driven pulley 21 and the outer side of the driving pulley 20 are jointly matched with a driving belt 22;

[0036] When in use, after the first motor 19 is started, the driving shaft 12 is driven to rotate through the driving pulley 20, the driving belt 22 and the driven pulley 21.

At this time, the conveyor belt 3 transports the fertilizer bag backwards so that the fertilizer bag can pass through the lower side of the first rotating frame 5 and the second rotating frame 6. At this time, the first rotating frame 5 can flatten the fertilizer bag for the first time through the rotating roller 7, so that the material in the fertilizer bag can be evenly distributed inside the fertilizer bag, and the second rotating frame 6 can flatten the fertilizer bag for the second time, thereby improving the flattening effect of the fertilizer bag.
