Description

Technical Field

[0001] The utility model relates to a front-stage dust removal device applied to a melon seed vacuum packaging machine. Background Art

[0002] Sunflower seeds are currently packaged in vacuum packaging, which not only saves on outer packaging and logistics costs, but also eliminates the need for deoxidizers, allowing the seeds to remain fresh for a long time. Because the seeds need to go through processes such as pipeline transportation, weighing and vibration feeding before being bagged, the seeds rub against each other and generate a certain amount of dust. After entering the bag, the dust will first make the bagged seeds look gray, affecting the appearance. Secondly, if the dust gathers at the mouth of the bag, the dust will be dissolved when the bag is vacuumed and hot-melted, affecting the sealing of the bag. Utility Model Content

[0003] The utility model aims to provide a pre-dust removal device for a melon seed vacuum packaging machine, which is used to solve the problem that melon seeds entering the packaging bag carry a small amount of dust that affects the appearance and sealing of the melon seed packaging.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] A front-stage dust removal device used in a melon seed vacuum packaging machine comprises a dust removal pipe, wherein the upper and lower ends of the dust removal pipe are respectively connected to a feed pipe and a discharge pipe, a plurality of conical caps and trumpet rings are arranged alternately in the dust removal pipe, the conical caps and trumpet rings are coaxial with the dust removal pipe, the tip of the conical cap faces the feed pipe, the open end of the trumpet ring faces the discharge pipe, and the dust removal pipe is connected to an exhaust pipe.

[0006] A jacket is arranged outside the dust removal pipe, a plurality of air exhaust holes are opened on the dust removal pipe below each horn ring, and the air exhaust pipe is communicated with the jacket.

[0007] An L-shaped air inlet pipe is connected to the lower end of the dust removal pipe. The air inlet pipe is fixedly connected to the lowest conical cap through a plurality of ribs, and each conical cap is connected to a support rod.

[0008] The lower end of the dust removal pipe is connected to the discharge pipe through a telescopic pipe, the upper end of the dust removal pipe is connected with a plug pipe, the feed pipe passes through the plug pipe and enters the dust removal pipe, and a sealing member is provided between the plug pipe and the feed pipe.

[0009] The beneficial effects of the utility model are as follows: before the melon seeds enter the packaging bag, the melon seeds entering the vacuum packaging machine are dusted through the exhaust pipe, so that the melon seeds in the packaging bag are kept clean and the dust is prevented from being hot-melted into the bag mouth. The device has a simple structure and does not require a large number of modifications to the existing packaging machine. It is easy to modify, so that the modification cost is low and simple and easy. The dust removal effect is good, and the production environment is cleaner and fresher, ensuring an excellent production environment and the health and safety of products and workers.

[0011] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.

[0012] Figure 2 It is a schematic diagram of the cross-sectional structure of the utility model.

[0013] In the figure: feed pipe 1, air hole 2, jacket 3, trumpet ring 4, dust removal pipe 5, telescopic pipe 6, discharge pipe 7, air inlet pipe 8, exhaust pipe 9, support rod 10, conical cap 11, insert pipe 12, seal 13, rib 14. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 and 2 As shown, a front-stage dust removal device applied to a melon seed vacuum packaging machine includes a dust removal pipe 5, the upper and lower ends of which are respectively connected to a feed pipe 1 and a discharge pipe 7, a plurality of conical caps 11 and a trumpet ring 4 are arranged inside the dust removal pipe 5, the outer ring of the trumpet ring 4 is welded and fixed to the inner wall of the dust removal pipe 5, the conical caps 11 and the trumpet ring 4 are alternately arranged, the conical caps 11 and the trumpet ring 4 are coaxial with the dust removal pipe 5, the tip of the conical cap 11 faces the feed pipe 1, and the open end of the trumpet ring 4 faces the discharge pipe 7, the conical cap 11 and the trumpet ring 4 form a corrugated channel inside the dust removal pipe 5, the dust removal pipe 5 is connected to an exhaust pipe 9, and the exhaust pipe 9 is connected to a vacuum cleaner through a hose.

[0016] When the utility model is implemented, the vertical pipe used for conveying melon seeds in the existing melon seed vacuum packaging machine is cut off, so that the pipe above the cut is the feed pipe 1, and the pipe below is the discharge pipe 7, and then the dust removal pipe 5 is connected to the pipe. When the melon seeds in the pipe fall vertically from the feed pipe 1, the melon seeds are discharged along the pipe. Figure 2 The A and B paths in the process alternately hit the conical cap 11 and the horn ring 4, so that the falling speed of the melon seeds is slowed down. At the same time, the melon seeds are used to impact and shake off the dust adsorbed on the melon seeds, so that it floats in the dust removal pipe 5, and then the dust is sucked away by the vacuum cleaner connected to the exhaust pipe 9.

[0017] A jacket 3 is provided outside the dust removal pipe 5, and a plurality of exhaust holes 2 are provided on the dust removal pipe 5 below each horn ring 4, and the exhaust pipe 9 is connected with the jacket 3. Since the exhaust holes 2 are provided below the horn ring 4, when the dust removal pipe 5 is evacuated, the melon seeds cannot be adsorbed onto the exhaust holes 2 by negative pressure, thus preventing the exhaust holes 2 from being blocked. At the same time, a plurality of exhaust holes 2 are provided to make the exhaust more uniform, so that the melon seeds falling on the conical caps 11 at each level can be dedusted nearby.

[0018] The lower end of the dust removal pipe 5 is connected to an L-shaped air intake pipe 8, which is fixedly connected to the lowest conical cap 11 through a plurality of ribs 14, and each conical cap 11 is connected to the support rod 10. During implementation, the air intake pipe is connected to the air pump, and the air blown out by the air pump passes through the conical cap 11 and is dispersed and moves upward to sweep the melon seeds, which can slow down the falling speed of the melon seeds and further improve the dust removal effect of the melon seeds.

[0019] The lower end of the dust removal pipe 5 is connected to the discharge pipe 7 through the telescopic pipe 6, and the upper end of the dust removal pipe 5 is connected with the insertion pipe 12. The feed pipe 1 passes through the insertion pipe 12 and enters the dust removal pipe 5. A sealing member 13 is provided between the insertion pipe and the feed pipe 1. This structure facilitates the disassembly and assembly of the dust removal pipe 5.

[0020] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
