DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] As Figures 1 to 6 shown, a woven bag sealing device comprises a rack 1, the rack 1 is provided with two side plates 2 oppositely arranged, and a connecting plate is fixedly installed between the lower ends of the two side plates 2 through bolts.

[0028] The frame 1 is provided with a placement plate 3, one end of which is driven by a power component to rotate up and down. The left and right sides of the rear end of the placement plate 3 are respectively fixed with a laterally extending rotation shaft 4 by bolts. The rotation shaft 4 is rotatably connected to the corresponding side plate 2, and the front end of the placement plate 3 can rotate up and down in a vertical plane. The power component is specifically an electric push rod 5, one end of the electric push rod 5 is hinged to the inner side of the side plate 2, and the other end is hinged to the bottom of the placement plate 3. When the electric push rod 5 contracts, it drives the front end of the placement plate 3 to rotate downward so that the placement plate 3 is in an inclined state, or when the electric push rod 5 extends, it drives the front end of the placement plate 3 to rotate upward so that the placement plate 3 is in a horizontal state.

[0029] The top rear end of the placement plate 3 is provided with a mounting groove, in which the lower heat-sealing plate 6 is fixedly mounted. The frame 1 is also provided with an upper heat-sealing plate 7, which is driven up and down by a power device. The tops of the two side plates 2 are respectively fixed with vertical plates by bolts, and a horizontal plate 8 is fixedly mounted between the upper ends of the two vertical plates by bolts. The power device is a cylinder 9 with a piston rod extending downward. The cylinder body of the cylinder 9 is fixedly mounted on the top of the horizontal plate 8 by bolts. The piston rod of the cylinder 9 passes downward through the horizontal plate 8 and is fixedly mounted with a fixed plate by bolts. The bottom of the fixed plate is fixedly mounted with bolts to the upper heat-sealing plate 7. The upper heat-sealing plate 7 is driven up and down by the expansion and contraction of the cylinder 9.

[0030] A pressure plate 10 for pressing the woven bag on the top of the placement plate 3 is fixed between the two side plates 2 by bolts. Specifically, the pressure plate 10 is located directly below the upper heat-sealing plate 7. A strip hole 11 is provided on the pressure plate 10 for the upper heat-sealing plate 7 to pass through. When the placement plate 3 is rotated to a horizontal state, the bottom of the pressure plate 10 is in contact with the placement plate 3, and the lower heat-sealing plate 6 moves to directly below the upper heat-sealing plate 7.

[0031] When in use, first, the electric push rod 5 is retracted to drive the placement plate 3 to rotate downward to an inclined state, such as Figure 2 As shown, at the same time, the top of the placing plate 3 is separated from the pressing plate 10; the woven bag to be sealed is placed on the top of the placing plate 3, and one end of the woven bag to be sealed is within the range of the lower heat-sealing plate 6; after the woven bag is placed, the electric push rod 5 is extended to drive the placing plate 3 to rotate upward to a horizontal state, so that the pressing plate 10 presses the woven bag on the top of the placing plate 3, and the end of the woven bag to be sealed is exposed from the strip hole 11 on the pressing plate 10; then the cylinder 9 can be extended to drive the upper heat-sealing plate 7 to move down and fit onto one end of the woven bag to be sealed At the end, the woven bag is heat-pressed and sealed by the upper heat-sealing plate 7 and the lower heat-sealing plate 6; after sealing is completed, the cylinder 9 contracts and drives the upper heat-sealing plate 7 to move up and return to its original position. At this time, the pressing plate 10 still presses the woven bag to prevent the woven bag from being lifted up by the rising upper heat-sealing plate 7; after the upper heat-sealing plate 7 returns to its original position, the electric push rod 5 contracts and drives the placing plate 3 to rotate downward to an inclined state, so that the sealed woven bag slides out from the lower end of the placing plate 3, and a collection box can be placed below the lower end of the placing plate 3 to collect the sealed woven bags.

[0032] The baffle 12 is movably mounted on the placement plate 3 and is used to prevent the woven bag from sliding down the inclined placement plate 3. When the woven bag to be sealed is placed on the top of the inclined placement plate 3, the baffle 12 blocks the low end of the woven bag, preventing the woven bag from sliding down the inclined placement plate 3.

[0033] The movable frame 13 driven by the adjusting mechanism is arranged on the placement plate 3 and moves in a direction perpendicular to the axis of rotation of the placement plate 3. The baffle 12 is movably mounted on the movable frame 13. Specifically, as shown in Figure 1 The top of the placement plate 3 is provided with a guide rod 14 parallel to the placement plate 3 and perpendicular to the axis of rotation of the placement plate 3. The two ends of the guide rod 14 are respectively fixedly mounted with support blocks, which are fixedly mounted on the placement plate 3 by bolts. The movable frame 13 is in the shape of a door, and one end of the movable frame 13 is slidably mounted on the guide rod 14. The drive device includes a lead screw 15 arranged parallel to the guide rod 14. The two ends of the lead screw 15 are respectively rotatably connected to bearing seats, which are fixedly mounted on the placement plate 3 by bolts. The lead screw 15 is driven to rotate by a first motor 16. One end of the lead screw 15 is connected to the rotating shaft of the first motor 16 by a coupling. The first motor 16 is mounted on the placement plate 3 by bolts. The guide rod 14 and the lead screw 15 are arranged opposite to each other. The end of the movable frame 13 away from the guide rod 14 is screwed on the lead screw 15. When the woven bag is placed on the top of the placement plate 3, the lead screw 15 is driven to rotate by the first motor 16, which in turn drives the movable frame 13 and the baffle 12 to slide along the guide rod 14, thereby adjusting the distance between the baffle 12 and the lower heat sealing plate 6. When the low end of the woven bag contacts the baffle 12, the high end of the woven bag can fall within the range of the lower heat sealing plate 6, so as to match the use of woven bags of different sizes.

[0034] The mounting box 17 driven by the drive device is arranged on the movable frame 13. As shown in Figure 6 The left and right ends of the mounting box 17 are respectively fixedly mounted with transversely extending connecting shafts 23 by bolts. The connecting shafts 23 are rotatably connected to the inner walls of the movable frame 13. The axis of rotation of the mounting box 17 is parallel to the axis of rotation of the placement plate 3. The drive device is a second motor 22 mounted on the right side of the movable frame 13 by bolts. The connecting shaft 23 at the right end of the mounting box 17 is connected to the rotating shaft of the second motor 22 by a coupling. The bottom of the mounting box 17 is open. The mounting plate 18 is slidably mounted in the mounting box 17. The baffle 12 is integrally formed at the bottom of the mounting plate 18.

[0035] A vertically extending slide rod 19 is fixedly mounted on the top wall of the mounting box 17. Two slide rods 19 are provided on the left and right sides. The upper ends of the slide rods 19 are screwed onto the top wall of the mounting box 17. The mounting plate 18 is slidably mounted on the two slide rods 19. The lower ends of the slide rods 19 are integrally formed with a stopper 20 for preventing the mounting plate 18 from falling off. A spring 21 is sleeved on the slide rod 19 located between the top wall of the mounting box 17 and the mounting plate 18.

[0036] In the initial state, the mouth of the mounting box 17 faces downward toward the placement plate 3, and the spring 21 pushes the mounting plate 18 downward toward the side of the placement plate 3 so that the lower end of the baffle 12 is close to the top of the placement plate 3. Figure 4 As shown, the baffle 12 prevents the woven bag from sliding down along the inclined placement plate 3.

[0037] After the woven bag is sealed and the electric push rod 5 drives the placement plate 3 to rotate downward to an inclined state, the second motor 22 can drive the installation box 17 to rotate in a specific direction, such as Figure 5 As shown, the mounting box 17 drives the baffle 12 below it to rotate forward clockwise. When the lower end of the baffle 12 is separated from the placement plate 3, the spring 21 pushes the baffle 12 to extend a longer dimension outside the mounting box 17, so that the baffle 12 can press the woven bag behind it during the rotation process and drive the woven bag to move forward and away from the lower heat-sealing plate 6, thereby preventing the woven bag from sticking to the lower heat-sealing plate 6, and allowing the sealed woven bag to slide smoothly along the placement plate 3.
