Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a ton bag feeding device and a use method thereof. Background Art

[0002] With the continuous development of the economy and the continuous advancement of science and technology, strong technical and material support is provided for the vigorous development of the manufacturing industry, thereby accelerating the pace of development of the manufacturing industry.

[0003] Feeding stations are commonly used in the pharmaceutical, chemical, food and other industries. Feeding stations are mainly used for unpacking, feeding, screening and unloading. On the production line, the main function of the feeding station is to transfer the material to the next process. However, the existing feeding stations mainly rely on manual bag opening and unloading during feeding. Manual bag opening and unloading has low work efficiency. At the same time, material dust will be generated during feeding, which will pollute the environment and is harmful to the health of operators.

[0004] In addition, the existing feeding method usually involves manually unpacking the bags and then feeding them into the storage silo. During the feeding process, the uneven pressure at the mouth of the ton bag can easily lead to a lot of material leakage at the mouth of the ton bag. When the material falls, the bag mouth is too fast, causing it to leave the storage silo, resulting in a large amount of material waste. Manual transportation of ton bags is time-consuming and laborious, which not only reduces production efficiency, but also increases equipment maintenance costs. The use of a feeding station can reduce the need for manual transportation, but the existing feeding station has a relatively complex structure and cannot make the material in the ton bag fall completely into the storage silo. Summary of the invention

[0005] The object of the present invention is to provide a ton bag feeding device, which is used to solve the problem in the prior art that the feeding device cannot completely press the bag opening of the ton bag, resulting in the bag opening being detached, leaking material and generating dust.

[0006] To achieve the above-mentioned purpose, the embodiment of the present application adopts the following technical scheme: a ton bag feeding device, comprising: a frame, the frame is arranged on a plane, a bracket is arranged on the upper surface of the frame, the bracket is fixedly connected to the frame, a gap is arranged between the frame and the bracket, a material guide frame is arranged between the frame and the bracket, the material guide frame is fixedly connected to the bracket; a dust removal bin is arranged below the material guide frame, the dust removal bin is fixedly connected to the frame, and the outer surface of the dust removal bin is provided with a A dust removal port is provided, which is used to connect an external dust suction device; a bag pressing device, which is arranged inside the dust removal bin, and the bag pressing device is arranged below the material guide frame, and the bag pressing device and the material guide frame are at the same center; a pressurizing device, which is arranged below the bag pressing device, and the pressurizing device is connected to the inside of the dust removal bin, and the pressurizing device and the bag pressing device are at the same center; a discharge bin, which is arranged inside the dust removal bin, and the discharge bin runs through the dust removal bin.

[0014] Furthermore, in an embodiment of the present invention, a gap is provided between the pressure plate and the outer periphery of the discharge bin, and a protrusion is provided on a side of the pressure plate facing the discharge bin.

[0015] Furthermore, in an embodiment of the present invention, an air supply bag is fitted on the surface of the protrusion, and the air supply bag is movably connected to the protrusion. A ventilation bag is connected to one side of the air supply bag, and the ventilation bag and the air supply bag are connected through an air duct; the ventilation bag is arranged on the inner wall of the discharge bin, and the air supply bag is arranged on the outer wall of the discharge bin.

[0017] The embodiment of the present invention also discloses a method for using the ton bag feeding device, comprising the following steps:

[0018] Place the ton bags and carry them to the surface of the bracket;

[0019] Place the bag opening. After the ton bag is placed on the surface of the bracket, place the bag opening below the ton bag into the inside of the placement plate. The bag opening slides inward along the outer wall of the airbag. The bag opening adheres to the outer wall of the airbag and the inner wall of the placement plate.

[0020] The bag opening is fixed, and the adjustment device moves down to drive the adjustment plate to move down, and at the same time drives the extrusion plate, the airbag, and the placement plate to move down. When the bottom surface of the placement plate contacts the pressure device, the adjustment device continues to fall back, and the extrusion plate and the placement plate move in relative directions. The extrusion plate applies pressure to the airbag to deform the airbag, thereby fixing and pressing the bag opening in the placement plate;

[0021] The pressurizing device is opened, and when the placement plate contacts the locking block of the pressurizing device, the downward force of the placement plate causes the pressure plate to rotate outward around the rotation axis, and the sealing plate also rotates outward at the same time;

[0022] The falling materials are untied after the bag opening is fixed, so that the materials in the ton bag fall down along the bag opening to the discharge bin. At the same time, the striking device pushes the bag pushing plate to beat the ton bag so that all the remaining materials in the ton bag can be discharged.

[0023] The beneficial effects of the present invention are as follows: First, the ton bag feeding device of the present invention reduces the operation of manual unloading, reduces material waste and reduces manual labor during the unloading of ton bags. First, after the extrusion plate, placement plate and airbag of the bag pressing device are placed inside the extrusion plate at the bag mouth of the ton bag, the bag mouth of the ton bag fits with the inner wall surface of the extrusion plate, and fits with the outer wall surface of the airbag, and fits with the inner wall surface of the extrusion plate. During the process of the adjustment device falling back, the extrusion plate and the placement plate move relative to each other. During the relative movement, the airbag gradually fits with the extrusion plate and the placement plate. At this time, the bag mouth of the ton bag is fixed in three directions by the placement plate, the extrusion plate and the airbag, thereby preventing the bag mouth from being separated from the bag pressing device during the unloading process of the ton bag, causing material leakage and reducing material waste. Secondly, through the bag pressing device and the pressurizing device, when the bag pressing device presses the bag mouth of the ton bag after the adjusting device falls back, the placement plate contacts the locking block of the pressurizing device, so that when the adjusting device falls back, the locking block exerts an upward force on the extrusion plate and the placement plate to move relative to each other, and the continuous falling back of the adjusting device causes a tighter pressure to be presented between the placement plate and the extrusion plate, so that the bag mouth of the ton bag is more tightly fixed inside the placement plate, and the falling back of the adjusting device causes the pressure plate of the pressurizing device to rotate around the rotation axis so that the inner wall surface of the locking block fits the outer wall surface of the placement plate to fix the position of the placement plate, and the sealing plate connected below the pressure plate opens to form a discharge opening to prevent material leakage when unloading is not needed. By fixing the position of the placement plate, the swing of the ton bag caused by using the striking device to push the bag pushing plate to hit the ton bag is reduced, which affects the tightness of the bag mouth of the ton bag.

[0055] Specifically, Figure 6 , 7 As shown in Figure 8, the bag pressing device 60 includes: an adjustment plate 601, a pressing plate 604, a placement plate 602, and an airbag 603. The adjustment plate 601 is arranged below the guide frame 101, a gap is arranged between the adjustment plate 601 and the guide frame 101, and the adjustment device 50 is arranged on opposite sides of the adjustment plate 601; the pressing plate 604 is arranged in the middle of the adjustment plate 601, the pressing plate 604 is fixedly connected to the adjustment plate 601, and a through hole is arranged in the middle of the pressing plate 604; the placement plate 602 is arranged below the pressing plate 604, the placement plate 602 is movably connected to the pressing plate 604, and a groove is arranged on the surface of the placement plate 602; the airbag 603 is arranged in the groove, and a gap is arranged between the airbag 603 and the groove. The gap between the pressing plate 604 and the placement plate 602 is smaller than the width of the airbag 603, and the pressing plate 604 moves up and down along the internal sliding groove of the placement plate 602. The adjusting device 50 is fixedly connected to the adjusting plate 601 , the adjusting device 50 is symmetrically arranged, the adjusting device 50 is fixedly connected to the frame 20 , and the adjusting device 50 is a telescopic motor. The pressurizing device 110 includes: a fixed plate 1101, a pressure plate, a locking block 1102, a sealing block, and a rotating shaft 1103. The fixed plate 1101 is arranged inside the dust removal bin 90, one end of the fixed plate 1101 is fixedly connected to the dust removal bin 90, and the other end of the fixed plate 1101 is connected to the discharge bin 40; the pressure plate is arranged inside the dust removal bin 90, the pressure plate is movably connected to the fixed plate 1101, and the pressure plate is arranged on the periphery of the discharge bin 40; the locking block 1102 is arranged above the pressure plate, the locking block 1102 is fixedly connected to the pressure plate, and one side of the locking block 1102 protrudes from the inner wall of the discharge bin 40; the sealing plate 1104 is arranged below the pressure plate, and the sealing plate 1104 is fixedly connected to the pressure plate; the rotating shaft 1103 is arranged inside the pressure plate, the rotating shaft 1103 passes through the fixed plate 1101, and a gap is left between the pressure plate and the fixed block.

[0056] Specifically, a gap is provided between the pressure plate and the outer periphery of the discharge bin 40 , and a protrusion is provided on a side of the pressure plate facing the discharge bin 40 .

[0057] Specifically, an air supply bag 1105 is fitted on the surface of the protrusion, and the air supply bag 1105 is movably connected to the protrusion. A ventilation bag 1106 is connected to one side of the air supply bag 1105. The ventilation bag 1106 and the air supply bag 1105 are connected by an air duct; the ventilation bag 1106 is arranged on the inner wall of the discharge bin 40, and the air supply bag 1105 is arranged on the outer wall of the discharge bin 40.

[0058] Specifically, there are multiple pressurizing devices 110, and the multiple pressurizing devices 110 are equally divided to form a complete circle; there are multiple air supply bags 1105, and the number of air supply bags 1105 and the pressurizing devices 110 is the same, and there are six pressurizing devices 110, which are evenly divided.

[0059] like Fig. 9 As shown, when in use, the ton bag is placed on the bracket 10, and the bag mouth of the ton bag is fitted with the inner wall surface of the extrusion plate 604, and the outer wall surface of the airbag 603, and the inner wall surface of the extrusion plate 604, forming a three-way fixation to prevent the bag mouth of the ton bag from falling off during the unloading process, and then the adjustment device 50 falls back. During the process of the adjustment device 50 falling back,

[0060] The downward movement of the adjustment plate 601 drives the extrusion plate 604 to move downward, and the placement plate 602 and the airbag 603 also move downward. When the lower bottom surface of the placement plate 602 contacts the inclined inner wall surface of the locking block 1102, the adjustment device 50 continues to fall back, thereby driving the extrusion plate 604 and the placement plate 602 to move relative to each other. During the relative movement of the extrusion plate 604 and the placement plate 602, the airbag 603 gradually fits with the extrusion plate 604 and the placement plate 602, so that the airbag 603 makes the bag mouth of the ton bag fit with the inner wall surfaces of the extrusion plate 604 and the placement plate 602 to form a stable fixation. The bag mouth of the ton bag is fixed in three directions by the placement plate 602, the extrusion plate 604, and the airbag 603, thereby preventing the bag mouth from being separated from the bag pressing device 60 during the unloading process of the ton bag, causing material leakage and reducing material waste. When the placement plate 602 contacts the locking block 1102, the force below the adjustment device 50 will apply pressure to the locking block 1102, so that the pressure plate connected to the locking block 1102 rotates around the rotation axis 1103, squeezing the air supply bag 1105 so that the air inside the air supply bag 1105 is transferred to the ventilation bag 1106. At the same time, the wall extending from the bottom of the placement plate 602 contacts the ventilation bag 1106 to fix the placement plate 602. The ventilation bag 1106 is set in a circular shape and is connected to the wall extending from the bottom of the placement plate 602. The locking block 1102, the air supply bag 1105, and the vent bag 1106 are used to fix the placement plate 602 in position to prevent the movement of the ton bag when the striking device 30 pushes the bag pushing plate 70 to beat and unload the ton bag, so that the bag opening of the ton bag pulls the placement plate 602, the air bag 603, and the squeezing plate 604 to move, causing the bag pressing device 60 to deviate and reduce the firmness of the bag opening of the ton bag. In addition, the air supply bag 1105 and the vent bag 1106 used to fix the placement plate 602 will not cause the placement plate 602 to form a forced positioning reduction. The damage of the placing plate 602 is reduced, and the air supply bag 1105 and the ventilation bag 1106 are kept at a high stability. When the placing plate 602 is fixed, the rotation of the pressure plate drives the sealing plate 1104 to move, thereby opening the seal of the discharge bin 40 to discharge the material from the discharge bin 40. When the sealing plate 1104 is set without fixing the bag opening of the ton bag, if the bag rope of the ton bag is loosened, the material is discharged from the ton bag and the sealing plate 1104 is used to keep the material inside the discharge bin 40, so as to prevent the material from leaking out of the device. The bag is then untied to allow the material to be discharged from the ton bag. While unloading, the bag pushing plate 70 is pushed by the striking device 30 to repeatedly contract, stretch out and beat the ton bag, so that all the remaining material in the ton bag is discharged, reducing the residual material inside the ton bag and the waste of resources. The dust generated during the unloading is sucked away by the negative pressure fan connected to the dust removal port 901 of the dust removal bin 90 to reduce pollution.

[0061] After the extrusion plate 604, the placement plate 602 and the airbag 603 of the bag pressing device 60 are placed inside the extrusion plate 604 at the bag mouth of the ton bag, the bag mouth of the ton bag fits with the inner wall surface of the extrusion plate 604, and fits with the outer wall surface of the airbag 603, and fits with the inner wall surface of the extrusion plate 604. During the falling back of the adjustment device 50, the extrusion plate 604 and the placement plate 602 move relative to each other. During the relative movement, the airbag 603 gradually fits with the extrusion plate 604 and the placement plate 602. At this time, the bag mouth of the ton bag is fixed in three directions by the placement plate 602, the extrusion plate 604 and the airbag 603, so as to prevent the bag mouth from being separated from the bag pressing device 60 during the unloading process of the ton bag, causing material leakage and reducing material waste. Through the bag pressing device 60 and the pressurizing device 110, when the bag pressing device 60 is pressed against the mouth of the ton bag after the adjustment device 50 falls back, the placing plate 602 contacts the locking block 1102 of the pressurizing device 110, so that when the adjustment device 50 falls back, the upward force of the locking block 1102 causes the squeezing plate 604 and the placing plate 602 to move relative to each other, and the continuous falling back of the adjustment device 50 causes a tighter pressure between the placing plate 602 and the squeezing plate 604, so that the mouth of the ton bag is more tightly fixed on the placing plate 602. Inside, the adjustment device 50 falls back to make the pressure plate of the pressurizing device 110 rotate around the rotating axis 1103 so that the inner wall surface of the locking block 1102 fits the outer wall surface of the placement plate 602 to fix the position of the placement plate 602, and the sealing plate 1104 connected below the pressure plate opens to form a discharge opening to prevent material from leaking when unloading is not required. By fixing the position of the placement plate 602, the swing of the ton bag caused by using the striking device 30 to push the bag pushing plate 70 to beat the ton bag is reduced, which affects the tightness of the bag mouth of the ton bag.

[0062] like Fig.10 , 11 As shown in FIG. 12 , the embodiment of the present invention further discloses a method for using a ton bag feeding device, comprising the following steps:

[0063] Place the ton bag and carry the ton bag to the surface of the bracket 10;

[0064] Place the bag opening. After the ton bag is placed on the surface of the bracket 10, place the bag opening below the ton bag into the inside of the placement plate 602. The bag opening slides inward along the outer wall of the airbag 603. The bag opening adheres to the outer wall surface of the airbag 603 and the inner wall surface of the placement plate 602.

[0065] The bag opening is fixed, and the adjustment device 50 falls back to drive the adjustment plate 601 to move downward, and at the same time drives the squeezing plate 604, the airbag 603, and the placement plate 602 to move downward. When the bottom surface of the placement plate 602 contacts the pressure device 110, the adjustment device 50 continues to fall back, and the squeezing plate 604 moves in relative directions with the placement plate 602. The squeezing plate 604 applies pressure to the airbag 603 to deform the airbag 603, thereby fixing and pressing the bag opening in the placement plate 602;

[0066] The pressurizing device 110 is opened, and when the placement plate 602 contacts the locking block 1102 of the pressurizing device 110, the downward force of the placement plate 602 causes the pressure plate to rotate outward around the rotation axis 1103, and the locking block 1102 fits with the outer wall of the placement plate 602. At the same time, the pressure plate squeezes the air supply bag 1105 to transport the air inside the air supply bag 1105 to the ventilation bag 1106. The ventilation bag 1106 becomes larger and fits with the wall extending from the bottom of the placement plate 602 to fix the placement plate 602. At the same time, the sealing plate 1104 also rotates outward to release the sealing state of the discharge bin 40.

[0067] The falling material is untied after the bag opening is fixed, so that the material in the ton bag falls downward along the bag opening to the discharge bin 40, and at the same time, the striking device 30 pushes the bag pushing plate 70 to beat the ton bag so that all the remaining materials in the ton bag are discharged.
