Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials, in particular to a feeding device for bagged materials. Background Art

[0002] The raw materials used in the construction, chemical and other industries, such as powders and granular materials, need to be packaged and transported in packaging bags. When in use, they are transported to the designated location through the conveyor belt, and the materials are placed in the hopper after the bags are unpacked.

[0003] If bagged materials are not properly transported or stored, especially bulk bagged materials, their surfaces are easily contaminated by other granular impurities or dust accumulation. When existing bagged materials are transported and fed via conveyor belts, they are generally unpacked manually or placed in unpacking machines by robotic arms. When workers or robotic arms unpack bags, they do not clean bags with dust or other granular impurities. Dust and other granular impurities entering the hopper will contaminate the materials, thereby affecting the quality of the products. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a bagged material feeding device, which can reduce the phenomenon of dust or granular impurities entering the hopper along with the material, thereby reducing the contamination of the material.

[0005] The technical solution of this utility model is as follows:

[0006] A bagged material feeding device comprises a conveyor belt located above a reference plane, the conveyor belt is provided with two sections and are arranged at intervals in the same direction along a conveying direction, a conveyor roller bed is provided between the two sections of the conveyor belt, the conveyor belt and the conveyor roller bed form a conveying line capable of conveying bagged materials, the conveyor roller bed comprises conveyor rollers arranged at intervals, and the length direction of the conveyor rollers is perpendicular to the transport direction of the conveyor belt, a soot blowing assembly is provided on one side of the conveyor roller bed, the soot blowing assembly comprises a first soot blower, and an air outlet of the first soot blower is arranged toward above the conveyor roller bed.

[0007] Two conveyor belts can be set, and a conveyor roller bed is arranged between the two conveyor belts. The two conveyor belts and the conveyor roller bed can form a conveying line for conveying bagged materials. A soot blowing assembly is arranged below, above or on one side of the conveyor roller bed. The soot blowing assembly can clean the outer packaging of the bagged materials passing through the conveyor rollers and remove impurities. A packing unpacker is arranged on the conveyor belt located in the conveying direction of the conveyor roller bed. The packing machine can unpack the bagged materials, and the packaging bags are blown out separately, and the materials fall into the hopper below the packing unpacker. Cleaning the packaging bags in advance can reduce the bagged materials from falling into the hopper along with the materials during the unpacking process of the packing unpacker, thereby reducing the phenomenon of dust and other particulate impurities contaminating the materials.

[0008] In order to clean the dust or particulate impurities on the upper and lower sides of the packaging bag at the same time, the sootblowing assembly also includes a second sootblower, and the second sootblower and the first sootblower are arranged on the opposite side of the conveying roller bed, and the first sootblower and the second sootblower are respectively arranged on the upper and lower sides of the conveying roller bed.

[0009] According to the above structure, the sootblowing assembly includes a support frame arranged on the upper and lower sides of the conveying roller bed, which is used to support and fix the first sootblower and the second sootblower. The length direction of the support frame is parallel to the length direction of the conveying roller, and the first sootblower and the second sootblower are respectively fixed on different support frames. Specifically, the sootblowing assembly also includes a first support frame arranged below the conveying roller and a second support frame arranged above the conveying roller. The length direction of the first support frame is parallel to the axis of the conveying roller. The first support frame is used to set the first sootblower, and the second support frame is provided with the second sootblower, and the air outlet of the second sootblower is arranged downward toward the conveying roller.

[0010] The first soot blower below blows air toward the packaging bag of the bagged material through the roller gap of the conveying roller, and the blowing area is limited. For this reason, the first support frame can move along the transport direction of the conveyor belt.

[0011] According to the above structure, the specific movement mode of the first support frame is that transverse slide rails are arranged on both sides of the conveying direction of the conveying roller bed, and the first support frame is movably connected to the transverse slide rails through transverse sliding assemblies. The transverse slide rails are arranged below the conveying rollers, and the length direction of the adjusting support rod is parallel to the axis of the conveying rollers. The first support frame can move repeatedly below the conveying rollers, driving the first soot blower to move repeatedly between different roller gaps, which can improve the soot blowing effect on the packaging bags. To ensure that the first support frame can move stably below the conveying rollers, two groups of transverse sliding assemblies are symmetrically arranged, and are respectively arranged on the transverse slide rails, and the protruding end of the transverse sliding assembly is connected to one end of the first support frame.

[0012] In order to facilitate the collection of larger impurity particles blown off, a dust collecting box is provided under the conveying roller. When larger impurity particles are blown off, they will fall downward when they are out of the blowing direction of the first soot blower.

The structure of the dust shield is that the side of the dust shield close to the first soot blower is an arc surface.

[0015] In order to increase the dust blocking area of ​​the dust shield, the dust shield is arranged on the opposite side of the first soot blower, and some dust particles blown away by the packaging bag can be blocked by the dust shield and fall into the dust collecting box for unified cleaning.

[0016] When the first soot blower blows soot on the packaging bag, dust will be blown into the air, which is harmful to the human body. In order to reduce the impact of the dust in the production workshop on the workers, a vacuum cleaner is arranged on one side above the conveying roller, and the dust suction port of the vacuum cleaner is arranged downward.

[0017] The beneficial effect of the utility model is that conveying rollers are arranged between the conveying belts, and soot blowing is performed through the soot blowing assembly arranged below the conveying rollers. When the bagged materials are unpacked by the unpacking machine, the phenomenon of dust or granular impurities entering the hopper along with the materials can be reduced, thereby reducing the phenomenon of material contamination.

[0018] The first support frame can move repeatedly under the conveying roller through the lateral sliding assembly, thereby driving the first soot blower to move repeatedly between different roller gaps, which can improve the soot blowing effect on the packaging bag.

[0025] like Figure 1A bagged material feeding device shown in the figure includes a conveyor belt 2 arranged on a reference plane and arranged at intervals. The conveyor belt 2 can be set to two, and a conveyor roller bed 1 is arranged between the two conveyor belts 2. The two conveyor belts 2 and the conveyor roller bed 1 can form a conveying line for conveying bagged materials. The conveyor roller bed 1 includes a conveyor roller 101 with a roller gap. A soot blowing assembly is arranged on one side of the conveyor roller bed 1. The soot blowing assembly can clean the outer packaging of the bagged material passing through the conveyor roller 101 and remove impurities. A depackaging machine 12 is arranged on the conveyor belt 2 located in the conveying direction of the conveyor roller bed 1. The depackaging machine 12 can unpack the bagged materials, and the packaging bags are blown out separately, and the materials fall into the hopper 13 below the depackaging machine 12. Cleaning the packaging bags in advance can reduce the bagged materials from falling into the hopper 13 together with the materials during the unpacking process of the depackaging machine 12, thereby reducing the phenomenon of dust and other particulate impurities contaminating the materials.

[0026] like Figure 2 As shown, the sootblowing assembly includes a first sootblower 3, a second sootblower 5, a first support frame 4 and a second support frame 6. The first support frame 4 is arranged below the conveying roller 101. The length direction of the first support frame 4 of this embodiment is consistent with the axial direction of the conveying roller, which is convenient for arranging multiple first sootblower 3. The first sootblower 3 is arranged on the first support frame 4. If the air outlet of the first sootblower 3 is inclined upward, the roller gap will be blocked by the conveying roller 101. For this reason, the air outlet of the first sootblower 3 is arranged vertically upward, and the air outlet of the first sootblower 3 can blow upward toward the bagged material on the conveying roller 101. Multiple first sootblower 3 can be provided, and multiple first sootblower 3 are arranged along the length direction of the first support frame 4.

[0027] like Figure 3As shown, the first soot blower 3 below passes through the roller gap of the conveying roller 101 to blow air to the packaging bag of the bagged material. The blowing area is limited. For this reason, transverse slide rails 7 are symmetrically arranged below the two ends of the conveying roller 101. The two transverse slide rails 7 are arranged in parallel. The length direction of the transverse slide rail 7 is perpendicular to the axis of the conveying roller 101 and is arranged in the horizontal direction. The first support frame 4 is slidably connected to the transverse slide rail 7 in the horizontal direction through the transverse sliding assembly 9, and the length direction of the adjustment support rod is parallel to the axis of the conveying roller 101. The first support frame 4 can move repeatedly under the conveying roller 101, driving the first soot blower 3 to move repeatedly between different roller gaps, which can improve the soot blowing effect on the packaging bag. The moving direction of the first soot blower 3 is horizontal movement, and the moving direction of the first soot blower 3 is perpendicular to the axis of the conveying roller 101. To ensure that the first support frame 4 can move stably under the conveying roller 101, the transverse sliding assembly 9 is symmetrically arranged in two groups, and is respectively arranged on the transverse slide rail 7, and the extended end of the transverse sliding assembly 9 is connected to one end of the first support frame 4. The structure of the transverse sliding assembly 9 is that the transverse sliding assembly 9 includes an electric push rod or a hydraulic cylinder, the extension rod of the electric push rod or the hydraulic cylinder is consistent with the length direction of the transverse slide rail 7, and the two transverse sliding assemblies 9 act simultaneously to drive the first support frame 4 and the first soot blower 3 to move.

[0028] During the process of soot blowing by the first soot blower 3 on the packaging bag, dust will be blown into the air. Long-term inhalation of dust is harmful to the human body. In order to reduce the impact of the production workshop filled with dust on the workers, a vacuum cleaner 11 is arranged on the side above the conveying roller 101. The vacuum cleaner 11 is an industrial vacuum cleaner 11. The suction port of the vacuum cleaner 11 is arranged downward or to one side of the conveying roller 101. The vacuum cleaner 11 can greatly reduce the phenomenon of dust generated by soot blowing being suspended in the production workshop, thereby reducing the harm to the workers' bodies.

[0029] The side of the packaging bag of the bagged material with dust or particulate impurities may be placed on the conveyor belt 2 on the front side, or on the back side on the conveyor belt 2. For this reason, according to the setting position of the first soot blower 3, the soot blower can also be set above the conveying roller 101, and the second support frame 6 is set above the conveying roller 101. The length direction of the second support frame 6 is consistent with the axial direction of the conveying roller 101, and the second support frame 6 is set in parallel with the length direction of the first support frame 4. The two ends of the second support frame 6 are fixedly connected to the frame body of the conveying roller bed 1 through vertical rods. A second soot blower 5 is arranged on the second support frame 6, and the air outlet of the second soot blower 5 is set downward. The air outlet of the second soot blower 5 can blow air forward downward, or it can blow air obliquely upward or obliquely downward, so as to blow the bagged material above the conveying roller 101. The second soot blower 5 cooperates with the first soot blower 3 to blow and dust the unclean side of the bagged material on the upper and lower sides, thereby reducing the phenomenon that particulate impurities enter the hopper 13 along with the material in the unpacking machine 12. A plurality of second sootblowers 5 may be provided, and the plurality of second sootblowers 5 are arranged at equal intervals along the length direction of the second supporting frame 6 .

[0030] In order to facilitate the collection of the larger impurities that are blown off, a dust collecting box 8 is provided below the conveying roller 101. When the larger impurities are blown off, they will fall downward when they are separated from the blowing direction of the first soot blower 3. Some of the impurities that are blown down by the second soot blower 5 will also fall into the dust collecting box 8 through the roller gap. The diameter of the upper port of the dust collecting box 8 can be set according to the distribution of the conveying roller 101. The larger the upper port of the dust collecting box 8, the easier it is to collect dust and particulate impurities. In order to reduce the particulate impurities from being blown away and scattered throughout the production workshop, a dust shield 10 is provided above the side wall of the dust collecting box 8. The structure of the dust shield 10 is that the dust shield 10 is a fan-shaped arc plate with an arc-shaped cross section. The side of the dust shield 10 close to the first soot blower 3 is an arc surface 101. The arc surface 101 can facilitate the particulate impurities to quickly slide into the dust collecting box 8, and then the particulate impurities and dust are uniformly collected. In order to increase the dust blocking area of ​​the dust blocking plate 10 , the upper end of the dust blocking plate 10 is located below the feeding end of the conveying roller bed 1 , and the lower end is connected to the side wall of the dust collecting box 8 .
