Description

Technical Field

[0001] This invention relates to the field of material mixing and processing equipment, specifically to a mixing equipment for tobacco processing. Background Technology

[0002] During the production of tobacco shreds, it is often necessary to use appropriate mixing equipment to mix different batches of tobacco raw materials to produce suitable tobacco shreds. Traditional mixing equipment for tobacco shred processing mainly uses mechanical stirring equipment. However, because tobacco shreds are prone to entanglement on mechanical stirring parts, the mixing process is difficult to control effectively. Therefore, pneumatic tobacco shred mixing equipment using airflow disturbance has begun to be used.

[0003] Mixing equipment that uses airflow disturbance to mix tobacco materials can overcome the problem of tobacco materials entanglement with the mixing components, but its mixing efficiency is still relatively poor. To ensure the uniformity of mixing, the mixing time can often be extended, which is obviously not suitable for the batch mixing of tobacco materials. Moreover, the existing mixing equipment for tobacco processing also has the problem of limited functionality, resulting in relatively weak adaptability.

[0004] Therefore, the research objective of this invention is to design a mixing device for tobacco processing that can effectively overcome the problem of entanglement between tobacco materials and mixing components, significantly improve the mixing effect and efficiency of tobacco materials, and effectively pre-dry the tobacco materials during the mixing process, thereby significantly improving the adaptability of the equipment. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a mixing device for tobacco processing, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A mixing device for tobacco processing, comprising:

[0008] A bracket is fixedly mounted on which a first drive motor with its output shaft facing downward is fixedly connected. The output shaft of the first drive motor is fixedly connected to an arc-shaped plate with its opening facing downward. A second drive motor with its output shaft facing inward is fixedly connected to each side of the arc-shaped plate.

[0009] The mixing container is arranged in the shape of a hollow sphere. The center of both sides of the mixing container are respectively connected to the output shaft of the second drive motor. The mixing container is provided with a corresponding inlet and outlet, and a corresponding cover is detachably installed at the inlet and outlet.

[0010] A multi-functional heating assembly includes a rotary joint located at the lower side of the center of the bottom of the mixing container. The fixed end of the rotary joint is connected to an external heat source, and a corresponding cover is fixedly installed on the rotating end of the rotary joint. A set of annular baffles located on both sides of the center line are symmetrically arranged in the middle of the mixing container. The cover is movably embedded between the set of annular baffles. Several corresponding guide holes are arranged at intervals on the mixing container between the set of annular baffles. A corresponding one-way valve is connected to each guide hole inward.

[0011] An exhaust assembly, located in the middle of the arc-shaped plate, is used to open a one-way valve that rotates through the lower side of the exhaust assembly.

[0012] The one-way valve includes an air guide pipe connected to the mixing container inside the guide hole. Inside the air guide pipe, there are spherical bodies that can form a seal around the guide hole via elastic elements. External hot air is introduced into the space formed by the cover and a set of annular baffles through the rotary joint. The hot air with increased air pressure pushes the spherical bodies of the one-way valve that rotate through the cover, causing the hot air to enter the mixing container.

[0013] The elastic element is a helical spring, and the inner end of the air guide tube is fixedly connected to a corresponding connecting rod. The ball is fixedly connected to the connecting rod by the helical spring.

[0014] The left and right sides of the cover are respectively fixed outward with corresponding sealing protrusions, and the outer ends of the sealing protrusions are respectively movable and abut against the inner sidewall of a set of annular baffles.

[0015] The front and rear ends of the cover are spaced apart from the mixing container and are fixedly connected to corresponding arc-shaped limiting plates facing upwards. Corresponding sealing rollers are rotatably installed between the arc-shaped limiting plates and the mixing container.

[0016] The sealing roller is made of high-temperature resistant rubber material, and the cross-section of the arc-shaped limiting plate is more than 1 / 2 circle.

[0017] The outer edge of the annular baffle is provided with continuous transmission teeth. The exhaust assembly includes a set of driven gears meshing and drivingly connected to the annular baffle. A corresponding transmission shaft is fixed between the driven gears. The transmission shaft is rotatably mounted on the arc-shaped plate, and a corresponding guide wheel is installed in the middle of the transmission shaft. At least one push rod corresponding to the ball is fixed on the guide wheel. During the rotation of the mixing container, the guide wheel rotates accordingly, and the push rods fixed on the guide wheel push the ball that rotates through the one-way valve at its bottom downwards one by one.

[0018] The cover can be detachably installed at the inlet and outlet of the mixing container via a threaded connection, and the outer end of the cover is provided with a handle for turning the cover.

[0019] The bracket includes a base plate, on which a corresponding column is fixedly connected. A corresponding support plate is horizontally fixedly connected to the top of the column, and the first drive motor is fixedly mounted on the support plate.

[0020] A corresponding workbench is fixedly installed on the base plate on the front side of the column, and the fixed end of the rotary joint is installed on the workbench.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] 1) This invention first adjusts the installation and driving method of the mixing container. During the mixing process, a first drive motor drives the downward-facing arc-shaped plate to rotate horizontally, thereby causing the mixing container mounted on the arc-shaped plate to rotate horizontally. At the same time, a second drive motor drives the mixing container to rotate vertically, so that the tobacco material inside the mixing container is simultaneously in a horizontal and vertical rotational environment, thereby ensuring the mixing effect and efficiency of the tobacco material.

[0023] 2) Building upon this, the present invention further includes a multifunctional heating component, comprising a rotary joint located at the lower side of the center of the bottom of the mixing container. The fixed end of the rotary joint is connected to an external heat source, and a corresponding cover is fixedly installed on the rotating end of the rotary joint. A set of annular baffles located on both sides of the center line are symmetrically arranged in the middle of the mixing container. The cover is movably fitted between the set of annular baffles. Several corresponding guide holes are arranged at intervals on the mixing container between the set of annular baffles, and corresponding one-way valves are connected inward at each of the guide holes. Through the intervention of the rotary joint and the movable fitting between the cover and the set of annular baffles, external hot air can be input into the space formed by the cover and the set of annular baffles through the rotary joint. After the air pressure in this space is increased, it can push the ball of the one-way valve that rotates through the cover, allowing the hot air to smoothly enter the mixing container. This not only improves the mixing effect and efficiency of tobacco materials through gas flow, but also effectively pre-dries the tobacco materials during the mixing process, thus significantly improving the equipment's adaptability.

[0024] 3) The one-way valve of the present invention includes an air guide pipe connected to a mixing container inside a guide hole. Inside the air guide pipe, spherical objects that can seal the guide hole are movably installed via elastic elements. External hot air enters the space formed by a cover and a set of annular baffles through a rotary joint. The increased air pressure pushes the spherical objects of the one-way valve, which rotates past the cover, into the mixing container. The design of the guide hole, air guide pipe, and spherical objects movably installed within the air guide pipe under increased air pressure effectively pushes the spherical objects, allowing hot air to smoothly enter the mixing container, thereby effectively ensuring the effectiveness of the present invention.

[0025] 4) The left and right sides of the cover of the present invention are respectively fixedly connected to corresponding sealing protrusions, and the outer ends of the sealing protrusions are respectively movable and abut against the inner sidewall of a set of annular baffles; and the front and rear ends of the cover are spaced apart from the mixing container and are respectively fixedly connected to corresponding arc-shaped limiting plates facing upwards, and corresponding sealing rollers are respectively rolled between the arc-shaped limiting plates and the mixing container. This allows the cover to be effectively and relatively movablely fitted into place under the premise of low friction, thereby significantly improving the practical effect of the present invention.

[0026] 5) The outer edge of the annular baffle of the present invention is provided with continuous transmission teeth, and the exhaust assembly includes a set of driven gears meshing and drivingly connected to the annular baffle. A corresponding transmission shaft is fixed between the driven gears, and the transmission shaft is rotatably mounted on the arc-shaped plate. A corresponding guide wheel is mounted in the middle of the transmission shaft, and at least one push rod corresponding to the ball of the one-way valve is fixedly connected to the guide wheel. During the rotation of the mixing container, the guide wheel rotates accordingly, and the push rod fixed to the guide wheel pushes the ball of the one-way valve rotating past its bottom downwards one by one. This timely removes the air stored in the mixing container, thereby effectively and significantly improving the practical effect of the present invention.

[0027] 6) The present invention also has the advantages of simple overall structure and low manufacturing, operation and maintenance costs. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] refer to Figure 1-5 A mixing device for tobacco processing, comprising:

[0036] A bracket 1 is fixedly mounted on the bracket 1 with a first drive motor 2 having its output shaft facing downwards. The output shaft of the first drive motor 2 is fixedly connected to an arc-shaped plate 3 with its opening facing downwards. A second drive motor 4 with its output shaft facing inwards is fixedly connected to both sides of the arc-shaped plate 3.

[0037] The mixing container 5 is arranged in the shape of a hollow sphere. The center of both sides of the mixing container 5 are respectively connected to the output shaft end of the second drive motor 4. The mixing container 5 is provided with a corresponding inlet and outlet. A corresponding cover 6 is detachably installed at the inlet and outlet.

[0038] The multi-functional heating component 7 includes a rotary joint 701 located on the lower side of the bottom center of the mixing container 5. The fixed end of the rotary joint 701 is connected to an external heat source, and a corresponding cover 702 is fixedly installed on the rotating end of the rotary joint 701. A set of annular baffles 703 located on both sides of the center line are symmetrically arranged in the middle of the mixing container 5. The cover 702 is movably embedded between the set of annular baffles 703. Several corresponding guide holes 8 are arranged at intervals on the mixing container 5 between the set of annular baffles 703. A corresponding one-way valve 9 is connected inward to each of the guide holes 8.

[0039] The exhaust assembly 10 is located in the middle of the arc-shaped plate 3 and is used to open the one-way valve 9 that rotates through the lower side of the exhaust assembly 10.

[0040] The present invention first adjusts the installation and driving method of the mixing container 5. During the mixing process, the first drive motor 2 drives the downward-facing arc-shaped plate 3 to rotate horizontally, thereby causing the mixing container 5 installed on the arc-shaped plate 3 to rotate horizontally; at the same time, the second drive motor 4 drives the mixing container 5 to rotate vertically, so that the tobacco material in the mixing container 5 is simultaneously in a horizontal and vertical rotational environment, so as to ensure the mixing effect and mixing efficiency of the tobacco material.

[0041] Based on this, the present invention further includes a multifunctional heating component 7, which includes a rotary joint 701 located on the lower side of the bottom center of the mixing container 5. The fixed end of the rotary joint 701 is connected to an external heat source, and a corresponding cover 702 is fixedly installed on the rotary end. A set of annular baffles 703 located on both sides of the center line are symmetrically arranged in the middle of the mixing container 5. The cover 702 is movably embedded between the set of annular baffles 703. Several corresponding guide holes 8 are arranged at intervals on the mixing container 5 between the set of annular baffles 703. Each guide hole 8 is connected to a corresponding one-way valve 9. Through the intervention of the rotary joint 701 and the movable embedding between the cover 702 and the set of annular baffles 703, external hot air can be input into the space formed by the cover 702 and the set of annular baffles 703 through the rotary joint 701. After the air pressure in this space is increased, it can push the ball 903 of the one-way valve 9 that rotates through the cover 702, so that the hot air can smoothly enter the mixing container 5. This not only improves the mixing effect and efficiency of tobacco materials through gas flow, but also effectively pre-dries the tobacco materials during the mixing process, thus significantly improving the equipment's adaptability.

[0042] The one-way valve 9 includes an air guide pipe 901 connected to the mixing container 5 inside the guide hole 8. Within the air guide pipe 901, spherical bodies 903, capable of sealing the guide hole 8, are movably mounted via elastic elements 902. External hot air enters the space formed by the cover 702 and a set of annular baffles 703 through the rotary joint 701. The increased air pressure pushes the spherical bodies 903 of the one-way valve 9, which rotates past the cover 702, allowing the hot air to enter the mixing container 5. The arrangement of the guide hole 8, the air guide pipe 901, and the spherical bodies 903 movably mounted within the air guide pipe 901 via elastic elements 902 effectively pushes the spherical bodies 903 under increased air pressure, ensuring that hot air can smoothly enter the mixing container 5 and thus effectively guaranteeing the effectiveness of the invention.

[0043] The elastic element 902 is a helical spring, and the inner end of the air guide tube 901 is respectively fixed with a corresponding connecting rod 904. The ball 903 is fixedly connected to the connecting rod 904 by the helical spring. In this embodiment, the connecting rod 904 and the elastic element 902, the ball 903 and the elastic element 902, and the connecting rod 904 and the air guide tube 901 are respectively fixedly connected by welding.

[0044] The cover 702 has corresponding sealing protrusions 11 fixedly attached to its left and right sides, respectively. The outer ends of the sealing protrusions 11 are movably abutting against the inner sidewalls of a set of annular baffles 703. The front and rear ends of the cover 702 are spaced apart from the mixing container 5 and are fixedly attached to corresponding arc-shaped limiting plates 12 facing upwards. Corresponding sealing rollers 13 are rotatably installed between the arc-shaped limiting plates 12 and the mixing container 5. This allows the cover 702 to be effectively and relatively movable into place with low friction, thereby significantly improving the practical effect of the present invention.

[0045] The sealing roller 13 is made of high-temperature resistant rubber material, and the cross-section of the arc-shaped limiting plate 12 is more than half a circle. This ensures that the sealing roller 13 does not easily deform during the sealing rotation connection process and ensures the limiting stability of the arc-shaped limiting plate 12 on the sealing roller 13.

[0046] The outer edge of the annular baffle 703 is provided with continuous transmission teeth. The exhaust assembly 10 includes a set of driven gears 1001 meshing and drivingly connected to the annular baffle 703. A corresponding transmission shaft 1002 is fixed between the driven gears 1001. The transmission shaft 1002 is rotatably mounted on the arc-shaped plate 3, and a corresponding guide wheel 1003 is mounted in the middle of the transmission shaft 1002. At least one push rod 1004 corresponding to the ball 903 is fixedly connected to the guide wheel 1003. During the rotation of the mixing container 5, the guide wheel 1003 rotates accordingly, and the push rod 1004 fixed to the guide wheel 1003 pushes the ball 903, which rotates through the one-way valve 9 at its bottom, downward in turn. This timely discharges the air stored in the mixing container 5, thereby effectively and significantly improving the practical effect of the present invention.

[0047] The cover 6 is detachably installed at the inlet and outlet of the mixing container 5 via a threaded connection, and the outer end of the cover 6 is provided with a handle 14 for turning the cover to facilitate the opening and closing of the cover 6.

[0048] The bracket 1 includes a base plate 101, on which a corresponding column 102 is fixedly connected. A corresponding support plate 103 is horizontally fixedly connected to the top of the column 102, and the first drive motor 2 is fixedly installed on the support plate 103.

[0049] A corresponding workbench 15 is fixedly installed on the base plate 101 on the front side of the column 102, and the fixed end of the rotary joint 701 is installed on the workbench 15.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
