Description

Technical Field

[0001] The invention belongs to the technical field of down processing, and in particular relates to a down suction and feeding mechanism based on down sterilization and mite removal treatment. Background Art

[0002] When processing down raw materials, at least the following processing steps are required: cleaning, dehydration, drying, sterilization, and then packaging through a feeder. The sterilization process is generally carried out using high temperature, ultraviolet light, chemical agents, etc. For duck down, the drying and sterilization processes are generally carried out simultaneously, using 120-130°C high temperature drying and sterilization and mite removal.

[0003] When sterilizing down, the down is generally placed on a tray and then put into a disinfection cabinet. For example, the down product sterilization and mite removal device disclosed in Application No. 202222042976.8 and the down product sterilization and mite removal device disclosed in Application No. 201821979536.2 require manual placement of the down before putting it in. After drying and sterilization, it also needs to be manually taken out and placed in a feeding mechanism for packaging, which requires manual operation. Since the dried duck down is easily flown when placed in a feeding mechanism in an open environment, it will also cause environmental pollution. Summary of the invention

[0004] The purpose of the present invention is to provide a down suction and feeding mechanism based on down sterilization and mite removal treatment in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A down suction and feeding mechanism based on down sterilization and mite removal treatment, comprising

[0007] The frame assembly comprises a cylindrical shell, a section of the circumferential wall of the shell is a mesh wall, and the circumferential wall is extended outward to form an outer arc-shaped cavity, and the remaining circumferential wall of the shell is also connected to a down suction pipe and a down discharge pipe;

[0008] A rotating mechanism, which is used to transport the down entering the down suction tube to the down discharge tube, comprises a mesh tube and a spoke plate arranged on the outer periphery of the mesh tube;

[0009] The airflow transfer assembly comprises a filling part extending from the side wall of the shell to the inner side of the mesh tube, and the circumferential surface of the filling part is provided with an inner arc cavity aligned with the mesh wall, a negative pressure cavity aligned with the down suction pipe, and a positive pressure cavity aligned with the down discharge pipe;

[0010] Among them, an alternating high-temperature airflow is formed between the outer arc cavity and the inner arc cavity through the rotating mechanism, which is used for drying and sterilizing and removing mites.

[0011] As a further optimization scheme of the present invention, the mesh cylinder is driven by a motor, the output shaft end of the motor passes through the shell and enters the interior, and is connected to the mesh cylinder through a circular base plate. The motor drives the base plate, which in turn drives the mesh cylinder to rotate, so that the mesh cylinder drives the spokes to rotate and transport the down between the spokes.

[0012] As a further optimization scheme of the present invention, the connecting parts of the suction and discharge pipes and the shell are all provided with connecting parts, which are aligned with the negative pressure chamber / positive pressure chamber and have sufficient width to maintain a larger suction range when the spoke plate rotates.

[0017] The beneficial effects of the present invention are:

[0018] The down is loaded by adopting negative pressure suction and pressurized discharge. The dehydrated semi-dried down is sucked in by negative pressure, and finally dried, sterilized and de-mite-removed during the loading process.

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1-6 As shown, a down suction feeding mechanism based on down sterilization and mite removal treatment includes

[0029] The frame assembly 1 comprises a cylindrical shell 11, a section of the circumferential wall of the shell 11 is a mesh wall 16, and the circumferential wall is extended outward to form an outer arc-shaped cavity 15, and the remaining circumferential wall of the shell 11 is also connected to a down suction pipe 13 and a down discharge pipe 14;

[0030] The rotating mechanism 2 is used to transport the down entering the down suction tube 13 to the down discharge tube 14, and includes a mesh tube 23 and a spoke plate 24 arranged on the outer periphery of the mesh tube 23;

[0031] The airflow transfer assembly 3 includes a filling portion 31 extending from the side wall of the housing 11 to the inner side of the mesh tube 23, and the circumferential surface of the filling portion 31 is provided with an inner arc cavity 32 aligned with the mesh wall 16, a negative pressure cavity 33 aligned with the down suction pipe 13, and a positive pressure cavity 34 aligned with the down discharge pipe 14;

[0032] Among them, an alternating high-temperature airflow is formed between the outer arc cavity 15 and the inner arc cavity 32 through the rotating mechanism 2 for drying, sterilizing and removing mites, preventing down from being trapped or blocked during the down transportation process by the rotating mechanism 2, and drying the down.

[0033] This solution uses negative pressure suction and pressurized discharge to load down. The dehydrated semi-dried down is sucked in by negative pressure, and final drying, sterilization and de-mite removal are performed during the loading process. The down is continuously flipped by alternating airflow to make it more fluffy. The alternating airflow can also prevent the surface holes of the mesh wall and the mesh tube from being blocked by down. When the spoke plate rotates along the inner wall of the shell, the down is adsorbed on the mesh tube so that the down will not be stuck in the gap when the spoke plate rotates. The closed loading method not only improves the fluffiness of the down, but also effectively prevents the dried fine down from floating into the air.

[0034] The mesh tube 23 is driven by a motor 21. The output shaft end of the motor 21 passes through the shell 11 and enters the interior, and is connected to the mesh tube 23 through a circular base plate 22. The motor 21 drives the base plate 22, which in turn drives the mesh tube 23 to rotate, so that the mesh tube 23 drives the spokes 24 to rotate, thereby transporting the down between the spokes 24.

[0035] The connecting parts of the down suction pipe 13, the down discharge pipe 14 and the shell 11 are all provided with connecting parts 12 to align with the negative pressure chamber 33 / positive pressure chamber 34, and the connecting parts 12 have a sufficient width to maintain a larger suction range when the spoke plate 24 rotates.

[0036] The feeding mechanism also includes a hopper 5, which is used to accommodate down. The down suction tube 13 penetrates into the hopper 5. The hopper 5 is used to temporarily store down. The front conveying device 6 can be used to feed the semi-dried down into the hopper 5. The semi-dried down can effectively reduce flying. Therefore, the front conveying device 6 does not need to be fully closed, and the down can be poured into the hopper 5. The airflow direction formed by the negative pressure tube 36 in the hopper 5 can also prevent the down from flying when pouring the down.

[0037] The negative pressure chamber 33 and the positive pressure chamber 34 are respectively provided with a negative pressure pipe 36 and a positive pressure pipe 37, which provide positive and negative air pressure through an air centrifugal pump 41. This scheme forms positive and negative airflows, and the negative pressure airflow is used to inhale down and the positive pressure airflow is used to discharge down.

[0038] The outer arc cavity 15 and the inner arc cavity 32 are respectively provided with a first alternating pipe 17 and a second alternating pipe 35. The first alternating pipe 17 and the second alternating pipe 35 form an alternating airflow through a four-way reversing valve 38, and the four-way reversing valve 38 provides positive and negative airflows through an air centrifugal pump 41. The specific gas flow direction is as follows: Figure 5-6 As shown, an alternating high-temperature airflow is arranged between the outer arc cavity 15 and the inner arc cavity 32 to achieve the effects of drying, sterilizing and removing mites, and can also prevent down from being blocked. Specifically, the alternating airflow can form backblowing to prevent small down from being stuck in the small holes of the mesh wall 16 and the mesh tube 23, and by forming a negative pressure in the inner arc cavity 32, the down is adsorbed on the surface of the mesh tube 23, and then when the mesh tube 23 rotates, the friction gap between the spoke plate 24 and the shell 11 will not get stuck in the down.

[0039] A heating device 43 and a dehumidification device 42 are also provided in the pipeline from the air centrifugal pump 41 to the four-way reversing valve 38. The dehumidification device 42 is used to remove moisture during the drying process, and can adopt adsorption dehumidification or condensation dehumidification in the prior art. The heating device 43 is used to heat the airflow to provide a sterilization and mite removal effect.

[0040] In order to further load and bag the down, a net bag 7 is used to hold the down, which is connected to a down discharge tube 14. The positive pressure airflow discharged from the down discharge tube 14 and the mixture of the down enter the net bag 7, and the airflow is discharged through the net bag 7. The down is filled in the net bag 7 in a fluffy state. The down discharge tube 14 can be provided with a valve.

[0041] The specific implementation method is as follows: the semi-dried down after dehydration is poured into the hopper 5, and the air centrifugal pump 41 forms a negative pressure in the negative pressure chamber 33. The negative pressure acts on the fine down tube 13 through the mesh tube 23, sucking the down, and the down enters the compartment between the spokes 24. The mesh tube 23 is driven to rotate, and the compartment is immediately connected to the outer arc cavity 15 / inner arc cavity 32 after leaving the negative pressure chamber 33. The outer arc cavity 15 / inner arc cavity 32 form an alternating high-temperature airflow to continuously turn over and dry the down, and the back-blowing airflow can prevent the mesh from being damaged. The wall 16 and the mesh tube 23 block the down. When the mesh tube 23 rotates, the inner arc cavity 32 is controlled to form a negative pressure, so that the down is adsorbed on the outer wall of the mesh tube 23 but not on the inner wall of the mesh wall 16, which facilitates the rotation of the spoke plate 24 against the inner side of the mesh wall 16 to prevent the down from being stuck. The compartment is immediately connected to the positive pressure cavity 34 after leaving the outer arc cavity 15 / inner arc cavity 32, and the positive pressure airflow flushes the down and air out of the down discharge pipe 14 and into the mesh bag 7, thereby completing the final drying of the down and sterilization and mite removal.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
