Description

Technical Field

[0001] The invention relates to the field of filling, in particular to an inclined feeding device for a valve bag packaging machine. Background Art

[0002] The feeding nozzle structure of the valve bag packaging machine in the prior art generally adopts a horizontal straight cylinder type. The bag opening of the valve bag is located at the top of the bag side and is horizontal with the bag. At the beginning of filling, the valve bag is horizontally inserted into the straight cylinder feeding nozzle. After filling, the bag is pushed out horizontally by a robot or manually.

[0003] During the valve bag filling process, the air brought by the material when it enters the bag will produce convection with the air in the bag, and the bag mouth itself will not completely fit the discharge port, which will cause the material to be sprayed out of the bag with the airflow. Due to the structure of the valve bag itself, when the filling material reaches a certain amount, the material will overflow from the bag mouth, especially before the filling is about to end, and severe powder spraying will occur, and the material will remain at the edge of the bag mouth, which is not conducive to normal sealing or cannot be completed. After the valve bag is filled, when the bag mouth is pushed out, the bag mouth and the discharge port will bring out the material, causing overflow. The above phenomenon occurs especially on the packaging equipment of powders and ultra-fine powders, and it cannot effectively solve the problems of material dust cleaning and recycling.

[0004] In addition, the horizontal straight cylinder structure cannot meet the high filling rate requirements of packaging. At the same time, the traditional feeding nozzle is directly connected to the filling machine or packaging machine. The vibration caused by the material transportation, the vibration of the equipment, and the blockage of the material pipeline will affect the filling accuracy, especially on weighing equipment with real-time weighing methods such as reduction and subtraction. Summary of the invention

[0005] The purpose of the present invention is to provide a technical solution for an inclined feeding device for a valve bag packaging machine to address the deficiencies in the prior art. By designing an inclined output component, the bag can also be inclined during the filling process, thereby improving the filling rate and making powder spraying and overflow less likely to occur.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A tilted feeding device for a valve bag packaging machine includes a feed pipe, and is characterized in that it also includes a tilted output component, the feed pipe is connected to the tilted output component, the material enters the feed pipe, and is then output through the tilted output component; through the design of the tilted output component, the bag can also form an inclined angle during the filling process, thereby improving the filling rate and being less likely to cause powder spraying and overflow.

[0008] Furthermore, the inclined output component includes an inclined feeding nozzle, a feed pipe and a straight feed pipe. The feed pipe is connected to the inclined feeding nozzle, and the straight feed pipe is inclinedly arranged on the inclined feeding nozzle. Through the design of the above-mentioned inclined structure, the inclined feeding nozzle and the weighing and metering feeding device can be isolated, which fully ensures that the real-time weighing of the material is not affected during the filling process, and ensures that there is enough space for the air in the bag to be discharged from the bag to the pipeline, avoiding the problem of a large amount of air and material appearing after the filling is completed.

[0009] Furthermore, the feed pipe is horizontally connected to the interior of the inclined feeding nozzle through the sheet metal, and an internal elbow is provided at the end of the feed pipe, and the internal elbow is suspended in the inner cavity of the inclined feeding nozzle. This structural design can connect the feed pipe to the internal feeding mechanism of the packaging machine, so that it is completely suspended inside the inclined feeding nozzle, ensuring that the feed pipe does not contact, bridge, or lean on the inclined feeding nozzle, ensuring that the cross-section dust suction device and the dust suction mechanism can effectively absorb and recycle the dust of the material. The internal elbow can not only protect the material from direct collision with the inner wall of the inclined feeding nozzle during discharge, causing the material to fall along the internal elbow, but also because the internal elbow is directly connected to the feed pipe and is in a real-time weighing state, it cannot contact the inner wall of the inclined feeding nozzle, thereby avoiding affecting the real-time weighing data.

[0010] Furthermore, a cut surface dust suction device is provided on the front end surface of the inclined feeding nozzle, and a flange is provided on the rear end surface of the inclined feeding nozzle. The flange is fixedly connected to the sheet metal through a shockproof mechanism. The cut surface dust suction device connects the inclined feeding nozzle with the dust suction equipment on the packaging machine, absorbs the dust and sends it to the dust suction equipment. The shockproof mechanism can reduce the vibration of the sheet metal and avoid the formation of gaps at the connection position due to vibration, thereby affecting the dust suction effect.

[0011] Furthermore, the center line of the straight pipe is extended to the flange, forming an angle a with the plane where the flange is located. The range of angle a is 30° to 60°, and the angle a is preferably 45°. The design of this angle can meet the requirements of inclined filling of valve bags, improve the filling rate, and is less likely to cause powder spraying and overflow.

[0012] Furthermore, the cut surface dust suction device includes a detachable cover plate and a first dust suction pipe. The detachable cover plate is connected to the inclined feeding nozzle. A dust suction port is arranged at the top corner of the detachable cover plate. A limiting groove is arranged on the sheet metal. One end of the first dust suction pipe is connected to the dust suction port through a connecting assembly, and the other end of the first dust suction pipe passes through the limiting groove and is connected to the dust suction equipment on the packaging machine. Through the design of the cut surface dust suction device, the dust of the material can be curbed during the material filling process, and the overflow of the powder spray and the material can be recovered once.

[0013] Furthermore, the connection assembly adopts one of sanitary stainless steel quick-change connectors, flanges or threaded pipes, preferably a sanitary stainless steel quick-change connector, which is easy to disassemble, clean, maintain, etc.

[0014] Furthermore, the anti-vibration mechanism includes an anti-vibration rubber block, and bolts are provided on both sides of the anti-vibration rubber block, and the bolts on both sides are staggered to lock the flange and the sheet metal with each other, thereby forming a staggered fixed connection, so that the components can be fixed to each other without contacting with metal parts, achieving the effect of vibration isolation and shock absorption, and eliminating the influence of the vibration generated by the vibrator on the parts that do not require vibration.

[0015] Furthermore, a vibration mechanism is provided on the inclined feeding nozzle, and the vibration mechanism includes at least one vibrator, which is vertically connected to the side of the inclined feeding nozzle. The vibrator is preferably a pneumatic vibrator. By installing the vibrator, not only can the material in the feed pipe fall quickly into the straight tube feed pipe, but also the material in the straight tube feed pipe can fall quickly into the valve bag, thereby avoiding the accumulation of material on the inner wall of the straight tube feed pipe.

[0016] Furthermore, a dust suction mechanism is provided on the rear side of the sheet metal, the dust suction mechanism includes a dust suction hood and a second dust suction pipe, the dust suction hood is fixedly connected to the rear side of the sheet metal, the dust suction hood is connected to the dust suction equipment on the packaging machine through the second dust suction pipe, and in actual use, the second dust suction pipe is preferably arranged at the bottom of the dust suction hood, and the second dust suction pipe is preferably a negative pressure pipe, so that the dust suction hood and the negative pressure pipe form a structure similar to a "blower", fully realizing the negative pressure vortex, greatly improving the dust suction effect, and the dust suction mechanism can realize secondary dust removal and recovery of powder spraying and material overflow.

[0017] Furthermore, a feed pipe inlet is provided on the side of the dust hood, and the feed pipe and the feed pipe inlet are suspended in the air. The dust hood is wrapped around the feed pipe and a gap is reserved to prevent the dust hood from touching the feed pipe.

[0018] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0019] 1. The present invention can avoid problems such as material dust and material overflow during the filling process, thereby improving work efficiency. At the same time, compared with the traditional filling structure, the filling rate of the valve bag is greatly improved, achieving an efficient filling effect per unit volume.

[0020] 2. Because the feeding end of the conveying pipe is connected with the silo, material driving equipment, weighing sensor, etc., the principle of overall weighing is adopted to weigh the entire equipment in real time. The purpose is to monitor the material conveying data in real time during the rapid filling process and to provide real-time feedback on the weight of the discharged material. Therefore, the conveying pipe is suspended in the inclined feeding nozzle to ensure that the dust and accumulation of the material do not cause gap blockage, and the vibrator is used to accelerate the falling of the material and improve the fluidity of the material in the pipe wall. Compared with the traditional filling structure, it can avoid the influence of equipment vibration, bag shaking, material conveying inertia, on-site construction and other factors on weighing, and realize the isolation of the conveying pipe, silo and weighing mechanism from the inclined feeding device.

[0021] 3. The overall structure of the inclined feeding device is independent and can be disassembled as a whole. It is easy to disassemble and clean, and is suitable for the packaging of fine powder and ultrafine powder.

[0022] 4. Through the design of the cross-section dust collection device, the dust of the material can be curbed during the material filling process, and the overflow of the powder spray and the material can be recovered once. The dust collection mechanism can realize secondary dust removal and recovery of the overflow of the powder spray and the material, greatly improving the dust collection effect.

[0042] A dust suction mechanism 8 is arranged on the rear side of the sheet metal 2, and the dust suction mechanism 8 includes a dust suction hood 14 and a second dust suction pipe 15. The dust suction hood 14 is fixedly connected to the rear side of the sheet metal 2, and the dust suction hood 14 is connected to the dust suction equipment on the packaging machine through the second dust suction pipe 15. In actual use, the second dust suction pipe 15 is preferably arranged at the bottom of the dust suction hood 14, and the second dust suction pipe 15 is preferably a negative pressure pipe, so that the dust suction hood 14 and the negative pressure pipe form a structure similar to a "blower", fully realizing the negative pressure vortex, greatly improving the dust suction effect, and the dust suction mechanism 8 can realize secondary dust removal and recovery of overflow of powder spray and materials, and a feed pipe inlet is arranged on the side of the dust suction hood 14, and the feed pipe 1 is suspended between the feed pipe 1 and the feed pipe inlet.
