Description

Technical Field

[0001] The invention discloses an automatic shaping and exhausting device for ton bags, belonging to the field of packaging machinery. Background Art

[0002] Patent document CN106864781A discloses a ton bag shaping machine, which uses a lifting plate to squeeze the ton bag from top to bottom, can flatten the conical upper end of the material, and discharge the gas inside the material, so that the material inside the bag is denser and the shape of the ton bag is flatter and more stable. However, for powder materials with more gas inside and good fluidity, this ton bag shaping machine is easy to expand around the ton bag during the process of flattening the ton bag, resulting in the ton bag size becoming larger and the shape not meeting the storage and transportation requirements, because there is no mechanism around the bag to limit the outward movement of the bag and the material, and because the bag opening is pressed by the plate, the gas inside the material is not easy to be discharged from the bag opening, resulting in poor exhaust effect. Summary of the invention

[0003] In order to solve the problems of irregular ton bag shapes and poor exhaust effects in existing ton bag shaping machines, the present invention proposes an automatic ton bag shaping and exhaust device, which comprises a ton bag conveyor 1, a bag mouth transfer device, and a five-sided shaping device, wherein the bag mouth transfer device is located above the rear section of the ton bag conveyor 1, and the five-sided shaping device is located above the front section of the ton bag conveyor 1. The bag mouth transfer device comprises a side bracket 2, and a transfer frame 4 is provided at the upper end of the side bracket 2. The transfer frame 4 is arranged along the conveying direction of the ton bag conveyor 1 and is located directly above the ton bag conveyor 1. A transfer drive mechanism 5 is provided on the transfer frame 4, and the transfer drive mechanism 5 drives the bag mouth transfer mechanism 3 to move longitudinally forward and backward on the transfer frame 4. The front end of the bag mouth transfer mechanism 3 is provided with two bag-supporting rods 6 arranged front and back and can swing toward each other. The device includes a square frame 7, and the front and rear ends of the square frame 7 are both provided with a lifting mechanism 11, and the lifting mechanism 11 is provided with a front and rear shaping mechanism 10, and the left and right ends of the square frame 7 are both provided with a left and right shaping mechanism 8, and the structure of the left and right shaping mechanism 8 is the same as that of the front and rear shaping mechanism 10, and the left and right shaping mechanism 8 is provided with a vertical shaping plate 84 that can be extended horizontally, and the upper left and right sides of the square frame 7 are symmetrically provided with an upper shaping mechanism 9, and a gap of a certain width is provided between the left and right upper shaping mechanisms 9, and a dust cover 12 is provided above the gap, and the dust cover 12 is connected to the upper shaping mechanism 9, and the upper shaping mechanism 9 is provided with a horizontal pressing plate 96 that can be extended vertically, and a lifting drive mechanism 13 is provided at the bottom of the square frame 7, and the lifting drive mechanism 13 drives the lifting mechanisms 11 at the front and rear ends to rise and fall synchronously.

[0004] The left and right shaping mechanisms 8 include a shaping bracket 81, which is slidably connected to a horizontal guide rod 82 arranged horizontally. A vertical shaping plate 84 is provided at the front end of the horizontal guide rod 82. Cross pressure rods 85 are provided at the left and right ends of the vertical shaping plate 84. The middle part of the vertical shaping plate 84 is hinged to the cylinder rod of the horizontal shaping cylinder 83, and the cylinder body of the horizontal shaping cylinder 83 is connected to the shaping bracket 81.

[0005] The upper shaping mechanism 9 includes a shaping beam 91, which is slidably connected to a vertical guide rod 92 arranged vertically. A horizontal pressure plate 96 is provided at the lower end of the vertical guide rod 92. The middle part of the horizontal pressure plate 96 is hinged to the cylinder rod of a vertical shaping cylinder 93. The cylinder body of the vertical shaping cylinder 93 is connected to the shaping beam 91. A bag opening cylinder 97 is also provided in the front and rear directions of the horizontal pressure plate 96. A bag opening suction cup 95 is provided on the cylinder rod of the bag opening cylinder 97. The bag opening cylinder 97 drives the bag opening suction cup 95 to realize left and right horizontal movement.

[0006] A dust removal cylinder 94 is also provided in the middle of the shaping cross beam 91 , and a cylinder rod of the dust removal cylinder 94 is connected to the upper outer side wall of the dust removal cover 12 , and the dust removal cylinder 94 drives the dust removal cover 12 to move up and down.

[0007] The working principle of the present invention is:

[0008] (1) Manually arrange the bag opening: After the ton bag filled with materials is transported to the bag opening transfer device, the bag opening is manually placed on the inward-inclined bag support rod 6, and the bag support rod 6 automatically swings outward to tighten the bag opening into a straight line shape;

[0009] (2) Open the bag mouth with suction cups: The ton bag conveyor 1 and the bag mouth transfer device are started synchronously to convey the ton bag forward to the five-sided shaping device. The I-shaped bag mouth is located in the gap between the left and right upper shaping mechanisms 9. The bag mouth suction cups 95 on the left and right sides extend to suck the two sides of the I-shaped bag mouth. The bag support rod 6 swings inward and detaches from the bag mouth. The bag mouth transfer device then returns backwards, and the bag mouth suction cups 95 on both sides retract to open the bag mouth. The dust removal cylinder 94 drives the dust removal cover 12 to insert downward into the opened bag mouth.

[0010] (3) Five-sided shaping and exhaust: The front and rear shaping mechanisms 10 at the front and rear ends are lowered to a low position and the vertical shaping plates are extended. The left and right shaping mechanisms 8 at the left and right ends simultaneously extend the vertical shaping plates 84. Then, the upper shaping mechanisms 9 on the left and right sides simultaneously extend the horizontal pressing plates 96 to perform five-sided extrusion shaping and exhaust on the ton bag. At this time, the gas and dust in the material are collected and discharged by the dust removal hood 12.

[0011] (4) Ton bag output: After shaping and exhausting, the bag opening suction cup 95 releases the bag opening, the front and rear shaping mechanisms 10 and the vertical shaping plates of the left and right shaping mechanisms 8 retract, the upper shaping mechanism 9 synchronously raises the horizontal pressing plate 96 and the dust cover 12, and then the front and rear shaping mechanisms 10 rise to a high position, and the ton bag conveyor 1 transports the shaped and exhausted ton bags forward to the next station.

[0012] The beneficial effects of the present invention are:

[0013] A. The mouth of the ton bag is kept upright by using the bag mouth transfer device. The four-sided shaping mechanism at the front, back, left and right sides and the upper shaping mechanism with gaps on the left and right sides can keep the shape of the ton bag regular when squeezing and shaping the ton bag. The gas contained in the material in the bag can be discharged from the upright bag mouth, achieving a good automatic shaping and exhaust effect.

[0014] B. Use the bag opening suction cup and the liftable dust hood to collect the dust-containing gas discharged by the powder material during the ton bag shaping process, thus avoiding dust leakage.

[0015] C. The bag mouth transfer device is used to automatically tighten the bag mouth and automatically transfer the bag mouth to the five-sided shaping device, avoiding the operator from entering the shaping device and improving the safety of equipment operation.
