Description

Technical Field

[0001] The utility model belongs to the technical field of graphite conveying, in particular to a sealing structure for a graphite powder conveying terminal. Background Art

[0002] Graphite is a mineral formed by natural deep crystallization from silicate magma under long-term high temperature and high pressure. Its primary component is carbon, but it also contains impurities such as iron, silicon, oxygen, and hydrogen. Graphite ore pretreatment involves crushing and screening to remove impurities and control particle size, or to reduce the size to a smaller powder. Graphite powder is a mineral powder primarily composed of a soft, black elemental carbon. Graphite powder is often bagged during production and processing, but traditional conveyors tend to generate large amounts of dust during the bagging process.

[0003] The prior art discloses a screw filling machine for powder, with the publication number CN220682701U. The granular powder in the storage bin is pushed out of the discharge port by a rotating pushing auger and then bagged. However, when the pushing auger stops pushing the material, some unfallen material remains on the spiral blades at the discharge port after the spiral-bladed pushing auger stops rotating. When the bag below the discharge port is removed and replaced again, some powder material often falls off. Moreover, when the discharge port is used to load the woven bag, powder escapes from the gap between the discharge port and the woven bag. This type of discharge port is not suitable for bagging, has poor sealing performance, and the black graphite powder that falls out easily pollutes the workshop environment. Utility Model Content

[0004] The invention provides a sealing structure for a graphite powder feeding terminal, aiming to solve the technical problem that a large amount of powder is easily dropped from the discharge port at the end of a filling machine when filling woven bags and polluting the workshop environment.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a sealing structure for the feeding end of graphite powder, including a body and a discharge port, characterized in that it also includes:

[0006] The feeding bag tube is placed at the end of the discharge port in a pipeline connection manner, elastic bands are provided on both sides of the feeding bag tube, and the end of the feeding bag tube is closed in a flat mouth shape;

[0007] The bag clamping arc frame is sealed and connected to the machine body outside the discharge port in a bolted connection manner;

[0008] The gluing sealing support ring is glued to the outside of the bag clamping arc frame, and the gluing sealing support ring is annular. An air cavity is provided inside the gluing sealing support ring, and the air cavity is inflated to expand the gluing sealing support ring outward;

[0009] The downward push air clamp arc is placed on both sides of the upper glue sealing support ring, and the downward push air clamp arc is inflated after being inflated;

[0010] The driving lifting device is placed at the lower part of the downward pushing air clamp arc.

[0011] Preferably, the feeding bag tube is made of elastic rubber material, and the number of the elastic bands is multiple and they are evenly placed on the outside of the flat-mouthed feeding bag tube for bonding connection.

[0012] Preferably, the elastic bands on the outside of the feeding bag tube are distributed in an X-shaped cross or parallel shape, and the feeding bag tube is in a normal state of being fitted and tightly closed with a flat mouth.

[0013] Preferably, when graphite powder flows out of the feeding bag tube, the elastic band is stretched into a propped-up shape, and when there is no graphite powder pushed out from the feeding bag tube, the elastic band rebounds to close the feeding bag tube.

[0014] Preferably, the driving lifting device includes a horizontal base plate, a support belt rib, a horizontal telescopic arm, a vertical telescopic rod and an elastic sealing sleeve. The inner side of the horizontal base plate is glued to the downward push air clamp arc, and the support belt rib is placed at the lower end of the downward push air clamp arc and is bolted to the horizontal base plate. The horizontal telescopic arms are provided at both ends of the outer side of the horizontal base plate, and the vertical telescopic rod is provided below each of the horizontal telescopic arms.

[0032] Below, the utility model will be further described in conjunction with the accompanying drawings:

[0033] Reference Figures 1 to 8 As shown, one aspect of the present invention provides a sealing structure for the feeding end of graphite powder, including: a body 1, a discharge port 2, a feeding bag tube 3, a bag clamping arc frame 4, a glue sealing support ring 5, a downward pushing air clamp arc 6, a driving lifting device 7 and an exhaust head 8.

[0034] Hereinafter, part of the structure and principle of the above components according to the present sealing structure will be described in detail.

[0035] Combine Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 As shown, the body 1 is the main body for connecting to the outer surface of the filling machine's discharge port 2. The discharge port 2 of the filling machine can be slidably or fixedly fitted to the body 1. A feed bag tube 3 is placed at the end of the discharge port 2 in a pipeline connection manner. The feed bag tube 3 is glued onto the end of the discharge port 2 by adhesive bonding. The feed bag tube 3 can be made of a rubber material with good elasticity. Elastic bands 31 are provided on both sides of the feed bag tube 3. The lower end of the feed bag tube 3 is closed in a flat-opening shape by the elastic preload of the elastic bands 31. There can be multiple elastic bands 31, and each of the multiple elastic bands 31 can be adhesively bonded to the outer surface of the feed bag tube 3. The multiple elastic bands 31 can be evenly distributed on the outer surface of the feed bag tube 3 in an X-shaped cross pattern or in parallel. The elastic bands 31 ensure that the lower end of the feed bag tube 3 is normally flat-open and tightly closed. When the discharge port 2 of the filling machine pushes the material outward, the graphite powder can flow out from the feed bag tube 3, and the outflowing graphite powder stretches the elastic band 31 into a propped-up shape; when the spiral blades in the discharge port 2 of the filling machine stop rotating and stop discharging from the discharge port 2 of the filling machine, the graphite powder between the end of the discharge port 2 and the feed bag tube 3 will remain in the feed bag tube 3, and the elastic band 31 outside the feed bag tube 3 will retract due to the elastic preload force and close the end opening of the feed bag tube 3, ensuring that the remaining graphite powder at the discharge port 2 will be stored by the feed bag tube 3 when the discharge port 2 is not discharging, ensuring that the graphite powder will not fall to the outside.

[0036] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, the outer ring of the machine body 1 outside the discharge port 2 can be provided with a bag clamping arc frame 4, and the bag clamping arc frame 4 and the machine body 1 can be bolted or welded, and the bag clamping arc frame 4 and the machine body 1 are sealed. The shape of the bag clamping arc frame 4 can be circular or elliptical. The outside of the bag clamping arc frame 4 is provided with an annular glue sealing support ring 5, and the glue sealing support ring 5 is made of a rubber material with good elasticity. The glue sealing support ring 5 is annular and is placed on the bag clamping arc frame 4 by adhesive sealing connection. An air cavity 51 is provided inside the glue sealing support ring 5. After the air cavity 51 is inflated, the glue sealing support ring 5 is expanded outward. The upper part of the glue sealing support ring 5 can be provided with an upper supporting ridge 52, and the upper supporting ridge 52 can be a raised edge-shaped platform. The upper supporting ridge 52 is placed on the bag clamping arc frame 4 to ensure that the glue sealing support ring 5 can play a supporting role after being inflated, thereby avoiding the phenomenon that the glue sealing support ring 5 is warped upward after being expanded.

[0037] Example 1

[0038] Reference Figures 1 to 7As shown, a woven bag 21 is placed on the conveyor roller 9 of the filling machine, and the opening of the woven bag 21 is placed outside the discharge port 2, the feeding bag tube 3, and the glue sealing ring 5. At this time, an air pump or other gas control device can quickly inflate the glue sealing ring 5, so that the glue sealing ring 5 expands and forms a close seal with the woven bag 21. In addition, the glue sealing ring 5 can also lock the position of the woven bag 21, ensuring that the woven bag 21 is stably placed outside the discharge port 2. The interior of the woven bag 21 is sealed with the discharge port 2 through the glue sealing ring 5, the bag clamping frame 4, and the machine body 1. This ensures that when the discharge port 2 pushes the material outward, dust will not escape through the gap at the upper opening of the woven bag 21, thus preventing dust from falling to the outside. Both sides of the woven bag 21 can be provided with downward pushing air clamping arcs 6, and the downward pushing air clamping arcs 6 are arc-shaped strips. The downward pushing air clamping arcs 6 and the upper glue sealing support ring 5 are structures that can be expanded after internal inflation. The driving lifting device 7 can move the downward push air card arc 6 in the upward, downward, left or right direction; the driving lifting device 7 includes a horizontal base plate 71, a supporting rib 72, a horizontal telescopic arm 73, a vertical telescopic rod 74 and an elastic sealing sleeve 75. The inner side of the horizontal base plate 71 is glued to the downward push air card arc 6, and the supporting rib 72 is placed at the lower end of the downward push air card arc 6 and bolted to the horizontal base plate 71. Both ends of the outer side of the horizontal base plate 71 are provided with the horizontal telescopic arms 73, and the horizontal telescopic arms 73 can drive the downward push air card arc 6 to move in the left or right direction; the vertical telescopic rod 74 is provided below the horizontal telescopic arm 73, and the vertical telescopic rod 74 can drive the horizontal telescopic arm 73 and the downward push air card arc 6 to move up or down synchronously; the outer sides of the telescopic ends of the vertical telescopic rod 74 and the horizontal telescopic arm 73 can be covered with the elastic sealing sleeve 75 to prevent the telescopic rod from being eroded by dust.

[0039] Reference Figure 7 As shown, Figure 7 This is a top view of the push-down air clamp arc and the woven bag 21 of Example 1 of the present utility model, as shown in FIG. Figure 7 As shown, the downward-pushing air-clamping arcs 6 are provided on both sides of the exterior of the woven bag 21 , the number of the downward-pushing air-clamping arcs 6 is 2, and the number of the driving lifting devices 7 is the same as the number of the downward-pushing air-clamping arcs 6 .

[0040] Example 2

[0041] Based on the above embodiments, Figure 1 and Figure 8As shown, when the upper glue sealing support ring 5 is inflated by the inflation device to tightly connect the woven bag 21, the downward push air clamp arc 6 can be adjusted to a position close to the outside of the woven bag 21 by the corresponding driving lifting device 7, so that the arc of the downward push air clamp arc 6 is located outside the arc of the woven bag 21 and lower than the upper glue sealing support ring 5. The downward push air clamp arc 6 is also inflated by the inflation device to tightly connect the woven bag 21. The downward push air clamp arc 6 and the upper glue sealing support ring 5 form a bite shape to firmly lock the woven bag 21, ensuring that the woven bag 21 will not fall off after being filled with materials, and ensuring smooth filling of materials into the woven bag 21. The support belt ridge 72 on the lower side of the downward push air clamp arc 6 can prevent the downward push air clamp arc 6 from deviating downward after expanding. The support belt ridge 72 and the upper support ridge 52 can form an effective block between the downward push air clamp arc 6 and the upper glue sealing support ring 5 to ensure the stability of clamping the woven bag 21.

[0042] Example 3

[0043] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, an exhaust head 8 is provided on one side of the discharge port 2. The exhaust head 8 consists of a flat cone plug 81, a side air hole cone 82, and an exhaust pipe 83. One end of the exhaust pipe 83 can be placed in the machine body 1 and sealed. The lower end of the exhaust pipe 83 is threadedly connected to the side air hole cone 82. The exhaust pipe 83 and the side air hole cone 82 form a pipeline passage. The lower end of the side air hole cone 82 is threadedly connected to the flat cone plug 81. The outside of the side air hole cone 82 is evenly drilled with air holes, which are connected to the exhaust pipe 83. The air holes are on the side of the inverted cone. The flat cone plug 81 is located below the air holes to block the air flow and prevent some dust from passing through. When pushing material into the woven bag 21, a small amount of gas inside the woven bag 21 can enter the exhaust pipe 83 through the side air hole cone 82, ensuring smooth bagging of the material.
