Description

Technical Field

[0001] This utility model relates to the field of packaging material storage technology, specifically a dustproof and moisture-proof automated packaging machine material storage. Background Technology

[0002] The material hopper of an automated packaging machine is a core functional component in an automated packaging production line. It stores and temporarily holds materials to be packaged, and stably supplies materials to subsequent packaging execution mechanisms (such as metering devices and filling mechanisms) according to a preset rhythm. It is a key "buffer and transfer hub" connecting the material pre-processing stage and the packaging execution stage. It receives materials from upstream processes, such as production line output, manual feeding, and conveyor belt feeding, forming a certain amount of material reserves. This prevents the packaging machine from stopping due to fluctuations in upstream material supply, such as intermittent feeding or insufficient material in a single feeding, thus ensuring the continuity of the packaging process.

[0003] In existing technology, such as the material storage bin of an automatic packaging machine disclosed in announcement number CN209536006U, there is a support frame. The storage bin body is fixedly connected to the support frame by bolts. The upper end of the adjusting plate is attached to the bottom of the end cover. A discharge port is fixedly connected to the bottom of the storage bin body, and a feeding pipe is threadedly connected to the lower end of the discharge port. The adjusting plate moves upward to open the end cover, while chicken essence powder is still present in the feeding chamber. This prompts the operator to add material to the storage bin body without affecting the bagging operation of the feeding pipe. This pre-stores the automatically fed powder, effectively ensuring the continuous production of the automatic packaging machine.

[0004] The existing material hopper opens its end cover by adjusting a plate, while still containing chicken essence powder in the feeding chamber. This prompts the operator to add more material to the storage hopper without affecting the bagging process of the feeding pipe. This allows for pre-storage of automatically fed powder, effectively ensuring continuous production of the automatic packaging machine. However, when temporarily storing materials, dehumidifying the material hopper is inconvenient. This can cause food ingredients, such as flour and grains, to absorb moisture, clump, mold, and even develop aflatoxin, resulting in poor practicality. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem that it is inconvenient to dehumidify the material storage area when the material is temporarily stored, food raw materials such as flour and grains will clump, mold, or even breed aflatoxin after absorbing moisture, resulting in poor practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A dustproof and moisture-proof material hopper for an automated packaging machine includes: a hopper body and fixed flanges; the fixed flanges are respectively disposed at both ends of the hopper body, and the fixed flanges are fitted with fixing bolts threaded to the hopper body; a discharge component is integrally fixed to the lower surface of one of the fixed flanges; and the machine also includes: A dehumidification mechanism and a dust removal mechanism are provided; the dehumidification mechanism is located on one side of the material silo, and the dust removal mechanism is located at the top of the material silo.

[0008] As a further embodiment of this utility model: the dehumidification mechanism includes: a nitrogen circulation shell, an air inlet pipe, a heating plate, a hollow fiber membrane, a connecting pipe, a fixing pipe, an installation component, a return pipe, a demister, and a carbon molecular sieve purification column. The nitrogen circulation shell is connected to one side of the material silo, and the upper end of the nitrogen circulation shell is connected to the air inlet pipe.

[0009] As a further improvement of this utility model: a heating plate is installed horizontally inside the nitrogen circulation shell, and a hollow fiber membrane that is detachably connected to the nitrogen circulation shell is provided below the heating plate.

[0010] As a further embodiment of this utility model: the lower surface of the nitrogen circulation shell is connected to a connecting pipe that communicates with the material storage body, and the upper surface of the nitrogen circulation shell is connected to a fixing pipe.

[0011] As a further embodiment of this utility model: the end of the fixed pipe is connected to an installation component, and the upper surface of the installation component is connected to a return air pipe that is interconnected with the material silo.

[0012] As a further improvement of this utility model: a demister is fixed inside the mounting component by screws, and a carbon molecular sieve purification column that is detachably connected to the mounting component is provided below the demister.

[0013] As a further embodiment of this utility model: the dust removal mechanism includes: a feeding component, an air curtain generator, an electrostatic electret, an ultrasonic transducer, a spiral blade, a worm gear, a worm, a stepper motor, a fixed bearing, and a fixed rod. The feeding component is fixed to the upper surface of another fixed flange and is interconnected with the material hopper. An air curtain generator is installed on the inner wall of the feeding component.

[0014] As a further improvement of this utility model: an electrostatic electret is fixed to the lower end of the inner wall of the feed piece by screws, and an ultrasonic transducer is installed inside the electrostatic electret.

[0015] As a further embodiment of this utility model: a spiral blade is provided at the lower part of the material silo body, which is rotatably connected to the discharge component, and a worm gear is fixed on the lower surface of the spiral blade.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The filtered nitrogen gas of this utility model enters the material silo through the connecting pipe, while the air at the top of the material silo enters the mounting component through the return pipe. The nitrogen gas purified by the demister and carbon molecular sieve purification column enters the nitrogen circulation shell again through the fixed pipe. After secondary drying by the heating plate and hollow fiber membrane inside the nitrogen circulation shell, it is sent back into the silo by the Roots blower through the connecting pipe. Combined with the nitrogen circulation and recovery mechanism, a slight positive pressure is maintained in the silo and external moisture is isolated, thereby achieving the function of moisture prevention and dehumidification.

[0018] 2. This invention uses a 30° downward-facing outlet angle of the air curtain generator to form an air curtain spiraling downwards along the inner wall of the feed component, guiding suspended dust to the electrostatic electret at the bottom. The electrostatic electret is made of PP melt-blown electret material and can adsorb the blown-off dust. When cleaning is required, the ultrasonic transducer inside the electrostatic electret is activated to shake off the dust from its outer surface. Attached Figure Description

[0020] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0023] Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides a dustproof and moisture-proof material hopper for an automated packaging machine, including: a material hopper body 1 and fixed flanges 2; the fixed flanges 2 are respectively disposed at both ends of the material hopper body 1, and fixed bolts 3 that are threadedly connected to the material hopper body 1 are installed inside the fixed flanges 2; a discharge component 4 is integrally fixed to the lower surface of one fixed flange 2, and the machine also includes: A dehumidification mechanism and a dust removal mechanism are provided; the dehumidification mechanism is located on one side of the material silo 1, and the dust removal mechanism is located at the top of the material silo 1.

[0024] Specifically, the dehumidification mechanism includes: a nitrogen circulation shell 5, an air inlet pipe 51, a heating plate 52, a hollow fiber membrane 53, a connecting pipe 54, a fixing pipe 55, an installation component 56, a return pipe 57, a demister 58, and a carbon molecular sieve purification column 59. The nitrogen circulation shell 5 is connected to one side of the material silo 1. The upper end of the nitrogen circulation shell 5 is connected to the air inlet pipe 51. A heating plate 52 is installed horizontally inside the nitrogen circulation shell 5. A hollow fiber membrane 53 that is detachably connected to the nitrogen circulation shell 5 is provided below the heating plate 52.

[0025] Furthermore, the nitrogen circulation shell 5 is equipped with an air inlet pipe 51 that is connected to the air source pre-treated by an external air compressor. The air is pre-treated to remove oil, water and dust. Then, the air enters the nitrogen circulation shell 5 through the air inlet pipe 51. The heating plate 52 heats the air. The air then passes through the hollow fiber membrane 53, and impurities such as oxygen and water vapor are discharged through the waste gas pipe through the membrane wall.

[0026] Specifically, the lower surface of the nitrogen circulation shell 5 is connected to a connecting pipe 54 that is connected to the material storage 1, the upper surface of the nitrogen circulation shell 5 is connected to a fixing pipe 55, the end of the fixing pipe 55 is connected to an installation component 56, and the upper surface of the installation component 56 is connected to a return gas pipe 57 that is connected to the material storage 1.

[0027] Furthermore, the filtered nitrogen enters the material silo 1 through the connecting pipe 54, while the air at the top of the material silo 1 enters the mounting component 56 through the return air pipe 57.

[0028] Specifically, a demister 58 is fixed inside the mounting component 56 by screws, and a carbon molecular sieve purification column 59 is provided below the demister 58 and is detachably connected to the mounting component 56.

[0029] Furthermore, the nitrogen purified by the demister 58 and the carbon molecular sieve purification column 59 enters the nitrogen circulation shell 5 again through the fixed pipe 55. Combined with the nitrogen circulation and recovery mechanism, it maintains a slight positive pressure inside the chamber and isolates external moisture, thereby achieving the function of moisture prevention and dehumidification.

[0030] In use, the material silo 1 is placed in a suitable position. Using the fixing flanges 2 on the discharge component 4 and the feed component 6, the discharge component 4 and the feed component 6 can be connected and fixed to the material silo 1 using fixing bolts 3. The nitrogen circulation shell 5 is equipped with an air inlet pipe 51 connected to an external air compressor pre-treated air source. This air undergoes pre-treatment to remove oil, water, and dust. The air then enters the nitrogen circulation shell 5 through the air inlet pipe 51. The heating plate 52 heats the air, which then passes through the hollow fiber membrane 53. Impurities such as oxygen and water vapor permeate through the membrane wall and are discharged through the exhaust pipe, ensuring the filtered air is properly cooled. Nitrogen gas enters the material silo 1 through the connecting pipe 54, while the air at the top of the material silo 1 enters the mounting part 56 through the return air pipe 57. After being purified by the demister 58 and the carbon molecular sieve purification column 59, the nitrogen gas enters the nitrogen circulation shell 5 through the fixed pipe 55 again. At this time, the solenoid valve on the air inlet pipe 51 is closed. After secondary drying by the heating plate 52 and hollow fiber membrane 53 inside the nitrogen circulation shell 5, it is sent back into the silo by the Roots blower through the connecting pipe 54. Combined with the nitrogen gas circulation and recovery mechanism, a slight positive pressure is maintained in the silo and external moisture is isolated, thereby achieving the function of moisture prevention and dehumidification.

[0031] In summary, during use, the filtered nitrogen gas enters the material silo 1 through the connecting pipe 54, while the air at the top of the material silo 1 enters the mounting component 56 through the return air pipe 57. The nitrogen gas, purified by the demister 58 and the carbon molecular sieve purification column 59, enters the nitrogen circulation shell 5 through the fixed pipe 55 again. After secondary drying by the heating plate 52 and hollow fiber membrane 53 inside the nitrogen circulation shell 5, it is then sent back into the silo by the Roots blower through the connecting pipe 54. Combined with the nitrogen circulation and recovery mechanism, a slight positive pressure is maintained inside the silo and external moisture is isolated, thereby achieving the function of moisture prevention and dehumidification. Example

[0032] Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0033] Specifically, the dust removal mechanism includes: a feeding component 6, an air curtain generator 61, an electrostatic electret 62, an ultrasonic transducer 63, a spiral blade 64, a worm gear 65, a worm 66, a stepper motor 67, a fixed bearing 68, and a fixed rod 69. The feeding component 6 is fixed to the upper surface of another fixed flange 2 and is interconnected with the material hopper 1. An air curtain generator 61 is installed on the inner wall of the feeding component 6. An electrostatic electret 62 is fixed to the lower end of the inner wall of the feeding component 6 by screws. An ultrasonic transducer 63 is installed inside the electrostatic electret 62.

[0034] Furthermore, since the air outlet angle of the air curtain generator 61 is 30° downward, an air curtain is formed that spirals downward along the inner wall of the feed piece 6, guiding the suspended dust to the electrostatic electret 62 at the bottom. The electrostatic electret 62 is made of PP meltblown electret material, which can adsorb the blown-off dust.

[0035] Specifically, a spiral blade 64 is provided at the bottom of the material hopper 1 and is rotatably connected to the discharge component 4. A worm wheel 65 is fixed on the lower surface of the spiral blade 64. A worm 66 is meshed at one end of the worm wheel 65. A stepper motor 67 is fixed at the input end of the worm 66 and is screwed to the discharge component 4. Fixed bearings 68 are fixed at both ends of the spiral blade 64. Two fixed rods 69, which are welded to the discharge component 4, are symmetrically fixed on the outer wall of the fixed bearings 68.

[0036] Furthermore, the stepper motor 67 drives the worm gear 66 to rotate, causing the worm gear 66 to mesh with the worm wheel 65 and rotate, thereby driving the spiral blade 64 to rotate. When the spiral blade 64 is running, it can discharge the raw material at the bottom downwards, thus achieving automatic discharge. The stability of the rotation of the spiral blade 64 can be ensured by the fixed bearing 68 and the fixed rod 69.

[0037] In use, the feeding component 6 is connected to the external raw material conveying equipment, and the discharging component 4 is connected to the inlet of the packaging machine. During operation, external raw materials enter through the feeding component 6, while clean air filtered by the G4 primary filter and F8 secondary filter is introduced through the air curtain generator 61. Because the outlet angle of the air curtain generator 61 is 30° downwards, an air curtain spirals downwards along the inner wall of the feeding component 6, guiding suspended dust to the electrostatic electret 62 at the bottom. The electrostatic electret 62 is made of PP meltblown electret material, which can effectively control the blown-off dust. When adsorption is required and cleaning is needed, the ultrasonic transducer 63 inside the electrostatic electret 62 is activated, which can shake off the dust on the outer surface of the electrostatic electret 62. When the raw material is discharged, the external PLC controller controls the stepper motor 67 to start, which in turn drives the worm 66 to rotate, so that the worm 66 meshes with the worm wheel 65 to rotate and drive the spiral blade 64 to rotate. Since the outer surface of the spiral blade 64 is in close contact with the inner surface of the discharge component 4, the raw material at the bottom can be discharged downward when the spiral blade 64 is running, thus realizing automatic discharge.

[0038] In summary, during use, the filtered nitrogen gas in the material hopper of this dustproof and moisture-proof automated packaging machine enters the material hopper body 1 through the connecting pipe 54. Meanwhile, the air at the top of the material hopper body 1 enters the mounting component 56 through the return air pipe 57. The nitrogen gas, purified by the demister 58 and carbon molecular sieve purification column 59, then enters the nitrogen circulation shell 5 through the fixed pipe 55. After secondary drying by the heating plate 52 and hollow fiber membrane 53 inside the nitrogen circulation shell 5, it is then returned to the hopper by the Roots blower through the connecting pipe 54, combining with the nitrogen circulation process. The receiving mechanism maintains a slight positive pressure inside the chamber and isolates external moisture, thereby achieving the function of moisture prevention and dehumidification. Furthermore, through the air curtain generator 61 with an air outlet angle of 30° downwards, an air curtain is formed that spirals downwards along the inner wall of the feed component 6, guiding the suspended dust to the electrostatic electret 62 at the bottom. The electrostatic electret 62 is made of PP meltblown electret material, which can adsorb the blown dust. When cleaning is required, the ultrasonic transducer 63 inside the electrostatic electret 62 is activated, which can shake off the dust on the outer surface of the electrostatic electret 62.
