[0002] The bag unpacker is an automated device specifically designed for unpacking bagged powders and granular materials. It efficiently and cleanly unloads the materials and recycles the bags. It replaces traditional manual unpacking with automated operations, reducing dust pollution and improving production efficiency.

[0003] During operation, the bag unpacker can cause material accumulation and bridging at the interface with the discharge station, hindering the free flow of materials (this phenomenon is common with powdered, granular, or fibrous materials). Furthermore, after the bag is cut, there are dead corners where the remaining material is not cleanly poured out. This part of the material is prone to dust during subsequent transportation, causing greater pollution to the working environment.

[0018] 2. Abandon the traditional negative pressure adsorption method of conducting materials and adopt the screw conveyor method to transport materials. This can avoid the problem of powder materials easily agglomerating due to their high density during transmission, and the problem of the vacuum suction port being easily blocked due to their small particle size and surface tension.

DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0027] See attached Figure 1 As shown, a package unpacking machine and its corresponding transmission component include a frame 1, a guide rail base 2 extending from the upper portion of the frame 1, and a driving member 3 mounted on the guide rail base 2 for transmitting a hooking mechanism 4 for hooking a packaging bag 25. It should be noted that the driving member 3 adopts a conventional moving and lifting structure, so that it can drive the hooking mechanism 4 to move along the X and Z axes, and the hooking mechanism 4 only needs to be able to hook the packaging bag 25. This solution does not improve the driving member 3 and the hooking mechanism 4.

[0028] See attached Figure 2-5 As shown, a discharge base 5 is fixed to the bottom of the frame 1. Cylinders 1 and 2, 8, are mounted on either side of the discharge base 5. The output end of cylinder 2, 8, is connected to a bag-pressing plate 6. An opening 13 is formed in the middle of the bag-pressing plate 6. A top ring 17, sized to match the opening 13, is mounted on the discharge base 5. By lowering the bag-pressing plate 6 until it contacts and abuts against the top ring 17, the excess portion of the bag opening of the packaging bag 25 is compressed and sealed. A bag-sealing mechanism 9 is mounted on the bag-pressing plate 6, with cylinder 1 7 serving as the power source for the bag-sealing mechanism 9.

[0029] The outer periphery of the top ring 17 is circumferentially connected to an L-shaped connecting block 18, and the inner wall of the discharge seat 5 is circumferentially provided with an annular groove 20, inside which a spring 19 is placed. Under normal conditions, the spring 19 extends upward above the discharge seat 5 and is connected to the lower end of the connecting block 18. It should be noted that the height of the bottom of different connecting blocks 18 is different to adapt to the height of the corresponding spring 19.

[0030] A chuck 24 is located within the discharge seat 5. A cutter 21 is circumferentially connected to the output end of the chuck 24, located below the top ring 17. The cutter 21 cuts obliquely, with the majority of the cutter 21 located within the orthographic projection below the top ring 17. The chuck 24 radially drives the cutter 21 in reciprocating motion. Specifically, the chuck 24 employs a conventional structure, such as a three-jaw chuck (with a conventional Archimedean screw groove meshing with the bottom jaws for movement, or a wedge screw mechanism), a pneumatic chuck, or the like. The center of the chuck 24 is through-hole, with a diameter larger than that of the top ring 17, to facilitate the passage of material.

[0031] The frame 1 may be provided with beating devices on both sides of the input packaging bag 25 to facilitate the accelerated discharge of the powder in the packaging bag.

[0032] A sealing seat 23 is also provided at the bottom of the bag pressing plate 6, the size of which is larger than the top ring 17 and smaller than the inner diameter of the discharge seat 5, so that the bag opening can be sealed for a second time when pressing down.

[0033] Since powder materials are easy to agglomerate due to their high density and their small particle size and surface tension make it easy to block the vacuum suction port, this embodiment abandons the traditional negative pressure adsorption and material transfer method and adopts a screw conveyor to transport the materials. Figure 1 A transmission pipe 11 communicating with the bottom of the discharge seat 5 is provided in the middle, a propeller blade with a long axis is provided in the pipe, the top of which is driven to rotate by a motor, and a discharge pipe 12 is opened on one side near the top.

[0034] See attached Figure 3-4 As shown, the bag sealing mechanism 9 includes a clamping jaw 91 (a conventional pneumatic clamping jaw 91 can be used) located on one side of the bag pressing plate 6. The outer side of the upper end of the clamping jaw 91 is connected to an L-shaped extension block 92. The outer side of the extension block 92 is connected to a pull rope 93. The other end of the pull rope 93 is connected to the output end of the cylinder 7, wherein the output end of the cylinder 7 is provided with a connector 96, and the connector 96 passes through the bag pressing plate 6. The bag pressing plate 6 is located on the outer side of the extension block 92 and is movably connected to the limiting block 94. The bottom of the limiting block 94 is provided with a long groove for the pull rope 93 to pass through. Under normal circumstances, the position of the clamping jaw 91 is pressed against so that it can descend synchronously with the cylinder 7, without affecting the movement trajectory between the bag pressing plate 6 and the cylinder 7, and there will be no cross-blocking problem. As shown Figure 5As shown, a push rod 22 is provided on one side of the discharge seat 5, and the push rod 22 corresponds to the position of the limit block 94 that engages the extension block 92, so that when the bag pressing plate 6 moves down to abut against the top ring 17, the limit block 94 can be pushed upward for a distance, thereby removing the restriction on the outward movement of the clamping jaws 91.

[0035] Furthermore, a guide seat 95 is provided on the bag pressing plate 6 , and the pull rope 93 is placed on a transverse groove provided in the guide plate to limit the trajectory of the pull rope 93 .

[0036] The bag sealing part adopts a conventional plastic cable tie (with the help of its one-way buckling structure). The plastic cable tie is selected to an appropriate size. After being clamped into a circle, it is placed on the accommodating groove 14 opened on the bag pressing plate 6. The bag pressing plate 6 is provided with a belt feeding groove 16 on the inner side of the clamping jaw 91, so that the free end of the plastic cable tie can pass through the clamping jaw 91 after clamping. The free end of the plastic cable tie can be pulled outward to achieve the locking of its inner circle, thereby achieving the sealing of the packaging bag 25. Each time the package is unpacked, the plastic cable tie needs to be loaded once, and the clamping jaw 91 is reset to the position where the limit block 94 is pressed down to block it.

[0037] See attached Figure 1-6 As shown, the application principle is as follows: 1. The bottom of the packaging bag 25 has a surplus opening part. First, the packaging bag 25 is hooked by the hooking mechanism 4 and placed on the top ring 17 of the discharge seat 5, so that the bottom of the packaging bag 25 is placed on the top ring 17, and a plastic cassette that is clamped into a circle is placed on the accommodating groove 14 on the bag pressing plate 6. The surplus part of the free end of the plastic cassette passes through the belt feeding groove 16 and is clamped at the clamping claw 91; 2. The second cylinder 8 is lowered to drive the bag pressing plate 6 to press the top ring 17 to preliminarily press the bottom of the bag opening; 3. The packaging bag 25 is lowered again and the second cylinder 8 synchronously drives the bag pressing plate 6 to press the top ring 17 downward, and cooperates with the spring 19 to press the top ring 17 into the discharge seat 5. At this time, the sharp part of the cutter 21 begins to pierce The material is discharged through the bag opening, and at the same time, the sealing seat 23 at the bottom of the bag pressing plate 6 covers the open opening 13 of the discharge seat 5; 4. The cutter 21 is driven by the chuck 24 to make radial reciprocating movement, and while cutting the bag opening, it breaks up the material at the discharge seat 5 to form a similar arch-breaking effect; 5. During the downward pressing process of the bag pressing plate 6, the push rod 22 pushes out the limit block 94 to eliminate the blocking force of the extension block 92. When the packaging bag 25 is discharged, the cylinder 7 descends and drives the clamping jaws 91 to move outward by stretching, so that the inner circle of the plastic cassette is gradually reduced to the basically sealed bag opening (the bag opening is located above the incision, and the damaged part is excluded below). After that, the clamping jaws 91 are released, and the hooking mechanism 4 can be reset to transfer and remove the packaging bag 25.

[0038] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
