Description

Technical Field

[0001] The utility model belongs to the technical field of ton bag manufacturing equipment, and particularly relates to an automatic ton bag bottom cutting device. Background Art

[0002] A ton bag, also known as a flexible intermediate bulk container (FIBC) or big bag, is a flexible transport packaging container. Ton bags are mainly woven from polyester fiber fabrics such as polypropylene. They are divided into three types in terms of shape: cylindrical, square, and U-shaped. They have the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and have sufficient strength in structure. The loading, unloading and handling of ton bags are very convenient, and the loading and unloading efficiency is significantly improved. Therefore, they have developed rapidly in recent years. The sewing of the bag bottom and the bag side is one of the key steps in making ton bags. When making a cylindrical ton bag by sewing, it is necessary to first cut the bag bottom into a circle and then sew it. At present, the cutting of the circular bag bottom is mostly manual operation. Workers first use a compass to draw a circle on the stacked fiber cloth layer according to the specification size, and then use an electric cutting machine to cut the fiber cloth layer according to the drawn line, and then circular bag bottoms can be obtained in batches. In order to stack the cut circular bag bottom fabric layer flat, when cutting the fiber cloth layer, the worker needs to hold and push the cutting machine with one hand and press the fiber cloth layer with the other hand. Prolonged use of the cutting machine will make the operator's hand quite tired. When cutting a relatively thick fiber cloth layer, two people need to cooperate with each other to complete the cutting work, which is time-consuming and laborious and has low work efficiency. Therefore, it is necessary to design an automatic ton bag bottom cutting device that can replace manual cutting of the fiber cloth layer. Summary of the Utility Model

[0003] Aiming at the above technical problems, the utility model provides an automatic ton bag bottom cutting device that can replace manual cutting of the fiber cloth layer and improve the cutting work efficiency of the ton bag bottom.

[0004] To solve the above technical problems, the technical solution of the utility model is: an automatic ton bag bottom cutting device, including a pedestal, an extension plate is hinged to the side of the pedestal, moving wheels are fixedly connected to the bottom end of the pedestal, a bottom plate is rotatably connected to the upper end of the pedestal, a support frame is fixedly connected to one side of the pedestal, a pressing plate is telescopically and rotatably connected to the support frame, the pressing plate is located directly above the bottom plate, a cutting mechanism is arranged on the upper end of the pedestal, a first scale is fixedly connected to the upper end of the pedestal on the side far from the cutting mechanism, a first indicating rod is arranged above the first scale, a second scale is fixedly connected to the extension plate, a second indicating rod is arranged above the second scale, a third scale is fixedly connected to the upper end of the pedestal on the side of the cutting mechanism, and a positioning indicating mark is installed on the cutting mechanism.

[0005] Further, a motor is fixedly connected inside the pedestal, and the output end of the motor is fixedly connected to the bottom plate.

[0006] Furthermore, two sliding rods are fixedly connected to the support frame, and the first indicating rod and the second indicating rod are respectively slidably connected to the sliding rods through sliding sleeves.

[0007] Furthermore, the cutting mechanism includes a moving plate and an electric knife-grinding cutting machine. The positioning indicator is fixedly connected to one side of the moving plate close to the third scale. The lower end of the moving plate is slidably connected to a horizontal rod through a connecting piece. Both ends of the horizontal rod are fixedly connected to the inner wall of the pedestal. The electric knife-grinding cutting machine is fixedly connected to the moving plate through a fixing rod, and the electric knife-grinding cutting machine is electrically connected to the control box.

[0008] Furthermore, a threaded block is fixedly connected below the moving plate, and a screw rod matching the threaded block is rotatably connected inside the pedestal. One end of the screw rod penetrates through the pedestal and is fixedly connected to a hand-operated disc.

[0013] The present utility model has the following advantages compared with the prior art:

[0014] 1. By setting the bottom plate and the pressing plate, the present utility model can press and drive the fiber cloth layer to rotate. By setting three groups of scales and indicators, the size of the bottom of the circular ton bag to be cut can be marked and determined on a square or irregular fiber cloth raw material. The cutting mechanism is set to replace manual cutting, completely replacing the current working process of manual pressing, marking, and then cutting during the cutting operation of the circular bottom of the ton bag. When using the present utility model to complete the cutting operation of the circular bottom of the ton bag, only one person needs to set the position according to the scale and then start the cutting mechanism to cut. Compared with the current full reliance on manual labor for cutting the circular bottom, the cutting work efficiency is further improved, and the labor intensity of personnel is reduced.

[0015] 2. By setting the screw rod and the threaded block to cooperate to move the cutting mechanism, it is convenient for the operator to adjust the position of the cutting tool to meet the cutting work of circular bottoms with different size specifications. By installing a presser foot on the cutting tool, it can prevent the fiber cloth layer from moving up and down with the tool during cutting, achieving a more precise cutting effect.

A first scale 11 is fixedly connected to one side of the upper end of the pedestal 1 away from the cutting mechanism 10. A first indicating rod 12 is arranged above the first scale 11. A second scale 13 is fixedly connected to the extended flat plate 5. A second indicating rod 14 is arranged above the second scale 13. It should be noted that both the first scale 11 and the second scale 12 coincide with the extension line of the radius of the circular bottom plate 6, and the included angle between the two extension lines is 90°. A third scale 15 is fixedly connected to the side of the upper end of the pedestal 1 where the cutting mechanism 10 is located. The first scale 11, the second scale 12, and the third scale 15 are all scales with a minimum scale of one millimeter, and the zero point of the scale is the center point of the bottom plate 6. A positioning indicating mark 16 is installed on the cutting mechanism 10.

[0023] A motor 4 is fixedly connected inside the pedestal 1, and the output end of the motor 4 is fixedly connected to the bottom plate 6. The motor 4 drives the bottom plate 6 to rotate. The motor 4 can be a variable-frequency motor, and the speed of the motor 4 can be adjusted by adjusting the adapted frequency converter, thereby adjusting the speed of the bottom plate 6. The motor 4 can also be a reduction motor cooperating with a speed reducer.

[0024] To assist in positioning the specific scale values of the first scale 11 and the second scale 13, so as to determine the actual size of the fiber cloth layer to be cut, two sliding rods are fixedly connected to the support frame 8, and the first indicating rod 12 and the second indicating rod 14 are respectively slidably connected to the sliding rods through sliding sleeves.
