Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging and feeding, in particular to a packaging and feeding dust-proof device. Background Art

[0002] Powder quantitative packaging machine is a common powder packaging machine, which is widely used in the field of feed processing. The current feeding method of powder quantitative packaging machine is auger feeding. The auger is set at the bottom of the silo and extends into the discharge pipe. The lower end of the auger is flush with the lower end of the discharge pipe. When the powder is bagged, the bag mouth is put on the outside of the discharge pipe, and the auger rotates to output the powder quantitatively. However, due to the centrifugal force of the powder driven by the rotation of the auger, the powder will be thrown to the periphery when it is output from the discharge pipe, which will cause dust to spread outward when the powder enters the packaging bag, affecting the workshop environment and easily causing damage to the health of workers.

[0003] Chinese utility model patent CN2019215434406 discloses a packaging machine for powder materials, including a working surface and a storage barrel, wherein the bottom of the working surface is fixedly connected with a support leg, the top of the working surface is movably connected with a ball bearing, the left and right sides of the top of the working surface are fixedly connected with an outer frame, the inner side of the outer frame is fixedly connected with a fixed frame, the inner surface of the fixed frame is fixedly connected with a storage barrel, the bottom of the storage barrel is fixedly connected with a dust cover, and the bottom of the dust cover is fixedly connected with a discharge port. In this packaging machine for powder materials, after the packaging bag is loaded through the discharge port, it is pushed to the bottom of the sealing machine by the ball bearing movably connected on the working surface, and the sealing machine starts working after pressing the switch, and the worker pushes the packaging bag to the right at a uniform speed for sealing operation, and after the sealing is completed, the packaging bag is pushed to the slideway to complete the entire sealing operation, achieving the effect of completing filling and sealing on one device. Among them, although the above patent provides a method of installing a dust cover at the bottom of the storage barrel to solve the dust problem during bagging, the structure of the dust cover is a trumpet-shaped wide-mouthed cover, which cannot prevent the powder from flying to the periphery and entering the packaging bag when the powder quantitative packaging machine discharges the material. Therefore, it cannot effectively solve the dust problem of the current powder quantitative packaging machine.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to provide a packaging feeding dust prevention device in view of the deficiencies in the prior art. The utility model has a scientific design and a simple structure. It is applied to a powder quantitative packaging machine, can avoid the generation of large dust during packaging feeding, and protect the health of workers.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a packaging feeding dust-proof device, including a buffer dust-proof cylinder, which is mounted on the outside of a discharge pipe of a powder quantitative packaging machine, the buffer dust-proof cylinder is bulging in the middle and shrinking at both ends, the lower end of the discharge pipe of the powder quantitative packaging machine is located in the buffer dust-proof cylinder, the diameter of the lower port of the buffer dust-proof cylinder is smaller than the diameter of the discharge pipe of the powder quantitative packaging machine, and the upper port of the buffer dust-proof cylinder is tightly attached to the outer wall of the discharge pipe of the powder quantitative packaging machine and is sealed and fixedly connected to the discharge pipe of the powder quantitative packaging machine.

[0007] The slow-feeding dust-proof cylinder includes an upper cover and a lower bucket. The upper cover is a conical cylinder structure that is small at the top and large at the bottom, and the lower bucket is a funnel structure that is large at the top and small at the bottom. The lower end of the upper cover and the upper end of the lower bucket are integrally formed and fixedly connected. The upper cover is coaxially mounted on the discharge pipe of the powder quantitative packaging machine. The lower end of the discharge pipe of the powder quantitative packaging machine is located in the middle of the upper end of the lower bucket, and the diameter of the bottom discharge port of the lower bucket is smaller than the diameter of the discharge pipe of the powder quantitative packaging machine.

[0008] The upper end of the upper cover is welded or riveted to the discharge pipe of the powder quantitative packaging machine.

[0009] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model directly sets a slow-feeding dust-proof cylinder on the discharge pipe of the powder quantitative packaging machine. The slow-feeding dust-proof cylinder includes an upper cover and a lower bucket. The upper cover is a conical cylinder structure with a small upper part and a large lower part, and the lower bucket is a funnel structure with a large upper part and a small lower part. The lower end of the upper cover is integrally formed and fixedly connected with the upper end of the lower bucket. The diameter of the bottom discharge port of the lower bucket is smaller than the diameter of the discharge pipe of the powder quantitative packaging machine. In this way, the upper cover and the lower bucket can completely cover the powder quantitative packaging machine. The lower end of the discharge pipe of the packaging machine, in this way, the upper cover and the lower bucket can completely cover the lower end of the discharge pipe of the powder quantitative packaging machine, to prevent the dust generated by the powder from being thrown out from the lower end of the discharge pipe of the powder quantitative packaging machine through the auger from diffusing, so that the powder is blocked by the upper cover and the lower bucket and then buffered in the lower bucket, and the powder slides down to the bottom discharge port of the lower bucket under the action of its own weight, and the packaging bag is directly covered on the bottom discharge port of the lower bucket, and the powder falls freely into the packaging bag, thereby avoiding the generation of large dust and protecting the health of workers.

[0013] like Figure 1As shown, the packaging feeding dust-proof device includes a buffer dust-proof cylinder, which is mounted on the outside of the discharge pipe 1 of the powder quantitative packaging machine. The buffer dust-proof cylinder is bulging in the middle and shrinking at both ends. The lower end of the discharge pipe 1 of the powder quantitative packaging machine is located in the buffer dust-proof cylinder, and the diameter of the lower port of the buffer dust-proof cylinder is smaller than the diameter of the discharge pipe 1 of the powder quantitative packaging machine. The upper port of the buffer dust-proof cylinder is tightly attached to the outer wall of the discharge pipe 1 of the powder quantitative packaging machine and is sealed and fixedly connected to the discharge pipe 1 of the powder quantitative packaging machine.

[0014] The slow-feeding dust-proof cylinder includes an upper cover 2 and a lower bucket 3. The upper cover 2 is a conical cylinder structure that is small at the top and large at the bottom, and the lower bucket 3 is a funnel structure that is large at the top and small at the bottom. The lower end of the upper cover 2 is integrally formed with the upper end of the lower bucket 3 and fixedly connected. The upper cover 2 is coaxially mounted on the discharge pipe 1 of the powder quantitative packaging machine.
