Description

Technical Field

[0001] The invention belongs to the technical field of material conveying, and in particular relates to a vacuum food processing feeder. Background Art

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicinal materials, but does not include items for therapeutic purposes. There are many kinds of food, and each different type of food has its own different flavors. Vacuumed food generally needs to be preserved in a vacuum and generally has a longer shelf life. When vacuumed food is processed, it needs to be loaded and a loading device is required.

[0003] Chinese patent application publication number (CN112121724A) discloses a quantitative feeding device for raw materials used in food processing, including a mounting plate, a lifting plate, a support rod and a top plate; a vertical storage cylinder is coaxially fixed on the lifting plate, an iron sheet is fixedly installed on the top of the mounting rod, and an electromagnet is provided on the lower surface of the top plate corresponding to the top of the iron sheet; a pull rope is wound on the winding roller, and the lower end of the pull rope is fixedly connected to the top of the storage cylinder; an upward weighing sensor is installed on the upper surface of the mounting plate, and the weighing sensor is connected to the motor through a controller. The device uses an electromagnet to absorb iron sheets and overcome their suction to quantify raw materials, ensuring that the food raw materials obtained each time are equal, which is convenient for food processing and use; the material is directly unloaded after quantification, which is convenient and quick to operate, and can carry out continuous quantitative feeding, thereby improving the continuity of the use of the device and improving food production efficiency. Some current food processing feeding devices often have material residue on the inner wall during feeding, and these residual materials are not fully utilized, resulting in waste of resources.

During the feeding process, the feeding screw rod can drive the driving gear to rotate, and the driving gear can drive the driven gear to rotate through meshing action, control the rotation of the reciprocating screw, and the reciprocating screw can drive the scraping assembly thereon to reciprocate on the inner wall of the injection pipe, and the feeding screw rod can be driven to rotate.

Through this design, the automatic scraping function in the feeding process can be effectively realized, and the scraping structure is designed to be movable. During the scraping process, unlike the traditional scraping structure, this structure can effectively send the material scraped off the inner wall to the outlet for effective utilization, which effectively solves the problem that the traditional scraping structure rotates but cannot move, resulting in the scraped material being unable to be sent to the outlet, which only treats the symptoms and not the root cause and cannot completely solve the problem of raw material waste.

[0026] In the present invention, a water tank is installed in a matching manner, and a steam conduction component is arranged on the water tank. When some materials that need to be continuously heated are loaded, the electric heating tube in the equipment can be turned on to increase the temperature of the materials. At the same time, the temperature can also be conducted to the water tank, and the water in the water tank is heated and heated until the water evaporates. The steam is conducted to the gas guide tube of the steam conduction component and gathered on one side of the air barrier. At this time, the thermal expansion column inside the installation sleeve will expand due to the high temperature. The expanded thermal expansion column can directly lift the connecting piece, and the connecting piece can synchronously lift the air barrier connected to it and rise synchronously. At this time The airflow barrier of the air guide square tube is opened, and the steam gathered on one side of the air barrier can be quickly introduced into the interior of the casing through the air guide square tube. The introduced steam can first pass through the gaps between the materials to reach various positions of the materials. The steam can have a good wetting effect on the materials, effectively solving the problem of dryness and hardness of the materials during the heating process, ensuring the overall softness of the materials, and avoiding the situation where the materials are too dry and hard, thereby effectively ensuring the feeding effect of the materials. At the same time, the introduced steam can also moisten the residual materials attached to the inner wall of the device, stably improving the scraping effect of the scraping assembly, and the use effect is good.

[0027] In the present invention, a driving assembly and a stirring assembly are provided inside, and when the material is heated, the heat expansion block of the driving assembly is also affected by the temperature and expands. At this time, the heat expansion block can push the movable frame to move downward, and can synchronously drive the threaded shaft frame to move downward. Since the threaded rod is threadedly connected to the screw hole provided inside the threaded shaft frame, the threaded rod will rotate, thereby synchronously driving the stirring plate outside it to rotate. The rotating stirring plate can stir the material added to the feeding funnel at that time, so that the added material can effectively and quickly enter the casing. Through this design, the stirring and introduction of the material can be achieved through the linkage effect, thereby avoiding the occurrence of material blockage to a large extent and ensuring the stability of subsequent feeding.

The outer surface of the annular scraper 141 is in close contact with the inner surface of the injection tube 1.

[0044] The specific implementation method is as follows: when feeding food raw materials, it is only necessary to turn on the driving motor 8. The driving motor 8 can drive the feeding screw 122 of the feeding assembly 12 to rotate. The feeding screw 122 can realize side guidance of the material, and finally the material is discharged through the injection pipe 1 to realize feeding. During the feeding process, the feeding screw 122 can drive the driving gear 121 to rotate.

The air blocking sheet 63 is embedded in the air blocking groove 67, and a sealing ring is provided on the outer surface of the air blocking sheet 63.

[0047] The specific implementation method is as follows: when loading some materials that need to be continuously heated, the electric heating tube in the equipment can be opened to increase the temperature of the materials. At the same time, the temperature can also be conducted to the water tank 7, and the water in the water tank 7 is heated and heated until the water evaporates, and the steam is conducted to the air guide tube 62 of the steam conduction component 6 and gathered on one side of the air barrier 63. At this time, the thermal expansion column 66 inside the mounting sleeve 61 will expand due to the high temperature, and the expanded thermal expansion column 66 can directly lift the connecting piece 65, and the connecting piece 65 can synchronously lift the air barrier 63 connected thereto and rise synchronously. At this time, the airflow barrier of the air guide square tube 64 is opened, and the steam gathered on one side of the air barrier 63 can be quickly introduced into the interior of the casing 2 through the air guide square tube 64. The introduced steam can first pass through the gaps between the materials to reach various positions of the materials, and the steam can have a good wetting effect on the materials.

[0048] This design effectively solves the problem of the material becoming dry and hard during the heating process, ensures the overall softness of the material, and avoids the material being too dry and hard, thereby effectively ensuring the material feeding effect. At the same time, the introduced steam can also moisten the residual material attached to the inner wall of the device, stably improving the scraping effect of the scraping component 14, and achieving good use effect.

[0050] A built-in guide rail 10 is fixedly installed on the inner wall of the casing 2, and a driving component 9 is slidably installed on the built-in guide rail 10. The driving component 9 includes a moving frame 92, and a slide groove 93 is arranged on the outer surface of the moving frame 92. The slide groove 93 is slidably connected to the built-in guide rail 10. A threaded shaft frame 94 is fixedly installed on the inner wall of the moving frame 92, and a heat expansion block 91 is arranged on the top surface of the moving frame 92. One end of the heat expansion block 91 is fixedly connected to the bottom surface of the top shell 3, and the threaded rod 43 is threadedly connected to the screw hole arranged inside the threaded shaft frame 94.

[0051] The specific implementation method is as follows: when the material is heated, the heat expansion block 91 of the driving component 9 is also affected by the temperature and expands. At this time, the heat expansion block 91 can push the movable frame 92 to move downward, and can simultaneously drive the threaded shaft frame 94 to move downward. Since the threaded rod 43 is threadedly connected to the screw hole set inside the threaded shaft frame 94, the threaded rod 43 will rotate, thereby synchronously driving the stirring plate 41 outside it to rotate. The rotating stirring plate 41 can stir the material added to the feeding funnel 5 at that time, so that the added material can effectively and quickly enter the casing 2.

[0052] Through this design, the stirring and introduction of materials can be achieved through the linkage effect, thereby avoiding the occurrence of material blockage to a large extent and ensuring the stability of subsequent feeding.

[0053] Working principle: When feeding food raw materials, it is only necessary to turn on the driving motor 8, which can drive the feeding screw 122 of the feeding assembly 12 to rotate, and the feeding screw 122 can realize the side guide of the material, and finally the material is discharged through the injection pipe 1 to realize feeding. During the feeding process, the feeding screw 122 can drive the driving gear 121 to rotate, and the driving gear 121 can drive the driven gear 15 to rotate through meshing, and control the rotation of the reciprocating screw 13. The reciprocating screw 13 can drive the scraping assembly 14 thereon to reciprocate on the inner wall of the injection pipe 1, and cooperate with the feeding screw 1 22 is used for feeding, and the residual material on the inner wall of the injection pipe 1 is scraped off; when feeding some materials that need to be continuously heated, the electric heating tube in the equipment can be turned on to increase the temperature of the materials. At the same time, the temperature can also be transmitted to the water tank 7, and the water in the water tank 7 is heated and heated until the water evaporates, and the steam is conducted to the gas guide tube 62 of the steam conduction component 6 and gathered on one side of the gas blocking sheet 63. At this time, the thermal expansion column 66 inside the mounting sleeve 61 will expand due to the high temperature, and the expanded thermal expansion column 66 can directly lift the connecting piece 65, and the connecting piece 65 can be synchronously lifted and The air blocking sheet 63 connected thereto rises synchronously, at which time the air flow barrier of the air guiding square tube 64 is opened, and the steam gathered on one side of the air blocking sheet 63 can be quickly introduced into the interior of the casing 2 through the air guiding square tube 64. The introduced steam can first pass through the gaps between the materials to reach various positions of the materials, and the steam can have a good wetting effect on the materials, effectively solving the problem of the materials being dry and hard during the heating process, ensuring the overall softness of the materials, and avoiding the situation where the materials are too dry and hard, thereby effectively ensuring the feeding effect of the materials. At the same time, the introduced steam can also wet the residual materials attached to the inner wall of the device. The material is lubricated and the scraping assembly 14 is stably improved to stabilize the scraping effect; when the material is heated, the heat expansion block 91 of the driving assembly 9 is also affected by the temperature and expands. At this time, the heat expansion block 91 can push the movable frame 92 to move downward, and can simultaneously drive the threaded shaft frame 94 to move downward. Since the threaded rod 43 is threadedly connected to the screw hole set inside the threaded shaft frame 94, the threaded rod 43 will rotate, thereby synchronously driving the stirring plate 41 outside it to rotate. The rotating stirring plate 41 can stir the material added to the feeding funnel 5 at that time, so that the added material can effectively and quickly enter the casing 2.
