Description

Technical Field

[0001] The invention relates to the technical field of material mixing processing equipment, in particular to a mixing equipment for tobacco processing. Background Art

[0002] During the tobacco production process, different batches of raw tobacco are often blended using mixing equipment to create the desired blend. Traditionally, this equipment primarily uses mechanical agitators. However, because the tobacco tends to entangle around the mechanical agitators, effectively controlling the mixing process is difficult. Therefore, pneumatic tobacco blenders that utilize airflow disturbances have begun to be used.

[0003] Although the mixing equipment that mixes tobacco materials by air flow disturbance can overcome the entanglement problem between tobacco materials and stirring parts, its mixing efficiency is actually relatively poor. In order to ensure the uniformity of mixing, it can often only be achieved by extending the mixing time, which is obviously not applicable for the batch mixing processing of tobacco materials. In addition, the existing mixing equipment for tobacco processing also has the problem of single function, resulting in its relatively weak adaptability.

[0004] Therefore, the research purpose of the present invention is to design a tobacco processing mixing equipment that can effectively overcome the entanglement problem between tobacco materials and stirring parts, and can significantly improve the mixing effect and mixing efficiency of tobacco materials, and can effectively pre-dry tobacco materials during the mixing operation of tobacco materials, thereby significantly improving the adaptability of the equipment. Summary of the Invention

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

[0006] The technical solution of the present invention is: A mixing device for tobacco processing, comprising: A bracket, on which a first drive motor with an output shaft facing downward is fixedly mounted, the output shaft of the first drive motor being fixedly connected to an arc-shaped plate with an opening facing downward, and second drive motors with output shafts facing inward being fixedly connected on both sides of the arc-shaped plate; The mixing container is arranged in a hollow spherical shape. The centers of both sides of the mixing container are respectively connected to the output shaft ends of the second drive motor. The mixing container is provided with a corresponding inlet and outlet, and a corresponding cover door is detachably installed at the inlet and outlet; The multifunctional heating assembly comprises a rotary joint provided on the lower side of the center of the bottom of the mixing container, the fixed end of the rotary joint being connected to an external hot air source, a corresponding cover being fixedly mounted on the rotating end of the rotary joint, a group of annular baffles being symmetrically provided in the middle of the mixing container and located on both sides of the center line thereof, the cover being movably embedded between the group of annular baffles, a plurality of corresponding guide holes being provided at intervals on the mixing container between the group of annular baffles, and corresponding one-way valves being connected inwardly to the guide holes respectively; The exhaust assembly is arranged in the middle of the arc-shaped plate and is used to open the one-way valve that rotates through the lower side of the exhaust assembly.

[0007] The one-way valve includes an air guide tube connected to the mixing container on the inner side of the guide hole. A ball that can close the guide hole is movably installed in the air guide tube through an elastic member. External hot air is input into the space formed by the cover and a group of annular baffles through the rotary joint. The hot air with increased air pressure pushes the ball rotating through the one-way valve of the cover, so that the hot air enters the mixing container.

[0008] The elastic member is a coil spring, the inner ends of the air guide tubes are respectively fixedly connected with corresponding connecting rods, and the sphere is fixedly connected to the connecting rods through the coil springs.

[0009] The left and right sides of the cover are respectively fixed outwardly with corresponding sealing ridges, and the outer ends of the sealing ridges are respectively movably abutted against the inner side walls of a group of the annular baffles.

[0010] The front and rear ends of the cover are spaced apart from the mixing container and are fixedly connected with corresponding arc-shaped limiting plates upwards. Corresponding sealing rollers are rotatably mounted between the arc-shaped limiting plates and the mixing container.

[0011] The sealing roller is made of high-temperature resistant rubber material, and the cross section of the arc-shaped limiting plate exceeds 1 / 2 of a circle.

[0012] The outer edge of the annular baffle is arranged in a continuous transmission tooth shape, and the exhaust component includes a group of driven gears meshing and connected to the annular baffle, and a corresponding transmission shaft is fixed between the driven gears, and the transmission shaft is rotatably mounted on the arc plate, and a corresponding guide wheel is installed in the middle of the transmission shaft, and at least one pushing rod corresponding to the sphere is fixed on the guide wheel. During the rotation of the mixing container, the guide wheel rotates with it, and the pushing rods fixed on the guide wheel push downward one by one the spheres of the one-way valve rotating through the bottom thereof.

[0013] The cover door is detachably mounted on the inlet and outlet of the mixing container by a threaded connection, and a handle for twisting the cover door is provided at the outer end of the cover door.

[0014] The bracket includes a base plate, a corresponding column is fixedly connected to the base plate, the top of the column is horizontally fixedly connected to the corresponding support plate, and the first drive motor is fixedly installed on the support plate.

[0015] A corresponding workbench is fixedly mounted on the base plate on the front side of the column, and the fixed end of the rotary joint is mounted on the workbench.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: 1) The present invention first adjusts the installation and drive method of the mixing container. During the mixing process, a first drive motor drives the downward-facing curved plate to rotate horizontally, thereby driving the mixing container mounted on the curved plate to rotate horizontally. Simultaneously, a second drive motor drives the mixing container to rotate vertically, so that the tobacco material in the mixing container is subjected to both horizontal and vertical rotation, ensuring the best mixing effect and efficiency.

[0017] 2) On this basis, the present invention further adds a multifunctional heating component, which includes a rotary joint arranged on the lower side of the center of the bottom of the mixing container, the fixed end of the rotary joint is connected to the external hot air source, and a corresponding cover is fixedly installed on the rotating end of the rotary joint. A group of annular baffles are symmetrically arranged in the middle of the mixing container on both sides of its center line. The cover is movably embedded between the group of annular baffles. A number of corresponding guide holes are arranged at intervals on the mixing container between the group of annular baffles, and the guide holes are respectively connected inwardly to corresponding one-way valves. Through the intervention of the rotary joint and the movable embedding arrangement between the cover and the group of annular baffles, the external hot air can be input into the space formed by the cover and the group of annular baffles through the rotary joint. When the air pressure in the space is increased, it can push the ball of the one-way valve rotating through the cover, so that the hot air can smoothly enter the mixing container. Therefore, the mixing effect and efficiency of the tobacco material can be improved through the gas circulation method, and the tobacco material can be effectively pre-dried during the mixing operation of the tobacco material, thereby significantly improving the adaptability of the equipment.

[0018] 3) The one-way valve of the present invention includes an air duct connected to the mixing container inside the guide hole. A sphere, capable of sealing the guide hole, is removably mounted within the air duct via an elastic member. External hot air is fed through a rotary joint into the space formed by the cover and a set of annular baffles. The elevated hot air pushes the sphere rotating through the one-way valve, allowing the hot air to enter the mixing container. The guide hole, air duct, and sphere removably mounted within the air duct via an elastic member effectively push the sphere under elevated pressure, allowing hot air to enter the mixing container, thereby effectively ensuring the effectiveness of the present invention.

[0019] 4) The cover of the present invention has corresponding sealing ridges fixedly attached to its left and right sides, each extending outward. The outer ends of these sealing ridges are movably abutted against the inner sidewalls of a set of annular baffles. Furthermore, the front and rear ends of the cover are spaced apart from the mixing container and fixedly attached upward with corresponding arc-shaped stoppers. Separate sealing rollers are rotatably mounted between the arc-shaped stoppers and the mixing container. This effectively and movably secures the cover in place with minimal friction, significantly enhancing the practical benefits of the present invention.

[0020] 5) The outer edge of the annular baffle of the present invention is provided with a continuous transmission tooth configuration, and the exhaust assembly comprises a set of driven gears meshingly connected to the annular baffle. A corresponding transmission shaft is fixedly connected between the driven gears, which is rotatably mounted to the curved 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. As the mixing container rotates, the guide wheel rotates with it, and the push rods fixed to the guide wheel push downward on each of the one-way valve balls that rotate through its bottom. This allows for the timely removal of air stored in the mixing container, thereby significantly further enhancing the practical effects of the present invention.

[0021] 6) The present invention also has the advantages of simple overall structure and low manufacturing, operation and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0029] refer to Figure 1-5 , a mixing device for tobacco processing, comprising: A bracket 1, on which a first drive motor 2 with an output shaft facing downward is fixedly mounted. The output shaft of the first drive motor 2 is fixedly connected to an arc-shaped plate 3 with an opening facing downward. Second drive motors 4 with output shafts facing inward are fixedly connected on both sides of the arc-shaped plate 3. The mixing container 5 is in the shape of a hollow sphere. The centers of both sides of the mixing container 5 are respectively connected to the output shaft ends of the second drive motor 4. The mixing container 5 is provided with a corresponding inlet and outlet. A corresponding cover door 6 is detachably installed at the inlet and outlet. The multifunctional heating assembly 7 comprises a rotary joint 701 provided 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 hot air source. A corresponding cover 702 is fixedly mounted on the rotating end of the rotary joint 701. A group of annular baffles 703 are symmetrically provided in the middle of the mixing container 5 on both sides of its center line. The cover 702 is movably embedded between the group of annular baffles 703. A plurality of corresponding guide holes 8 are provided at intervals on the mixing container 5 between the group of annular baffles 703. The guide holes 8 are respectively connected inwardly to corresponding one-way valves 9. The exhaust assembly 10 is provided 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 .

[0030] The present invention first adjusts the installation and drive method of the mixing container 5. During the mixing process, the first drive motor 2 drives the downward-opening curved plate 3 to rotate horizontally, thereby driving the mixing container 5 mounted on the curved plate 3 to rotate horizontally. Simultaneously, the second drive motor 4 drives the mixing container 5 to rotate vertically, so that the tobacco material in the mixing container 5 is subjected to simultaneous horizontal and vertical rotation, ensuring the mixing effect and efficiency of the tobacco material.

[0031] On this basis, the present invention further adds a multifunctional heating assembly 7, which includes a rotary joint 701 disposed at the lower center of the bottom of the mixing container 5. The fixed end of the rotary joint 701 is connected to an external hot air source, and a corresponding cover 702 is fixedly mounted on the rotating end. A set of annular baffles 703 are symmetrically arranged in the middle of the mixing container 5, located on both sides of its centerline. The cover 702 is movably embedded between the set of annular baffles 703. A plurality of corresponding guide holes 8 are provided at intervals on the mixing container 5 between the set of annular baffles 703. Each of these guide holes 8 is connected inwardly to a corresponding one-way valve 9. Through the intervention of the rotary joint 701 and the movable embedding arrangement 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. When the air pressure in this space is increased, it pushes the ball 903 of the one-way valve 9 that rotates through the cover 702, allowing the hot air to smoothly enter the mixing container 5. Therefore, the mixing effect and efficiency of the tobacco material can be improved through the gas circulation method, and the tobacco material can be effectively pre-dried during the mixing operation of the tobacco material, thereby significantly improving the adaptability of the equipment.

[0032] The one-way valve 9 includes an air guide tube 901 connected to the mixing container 5 inside the guide hole 8. A ball 903 capable of sealing the guide hole 8 is movably mounted in the air guide tube 901 via an elastic member 902. External hot air is input into the space formed by the cover 702 and a set of annular baffles 703 via the rotary joint 701. The hot air, with increased pressure, pushes the ball 903 rotating through the one-way valve 9 of the cover 702, allowing the hot air to enter the mixing container 5. The arrangement of the guide hole 8 in the mixing container 5, the air guide tube 901, and the ball 903 movably mounted in the air guide tube 901 via the elastic member 902 allows the ball 903 to be effectively pushed under conditions of increased pressure, allowing the hot air to smoothly enter the mixing container 5, thereby effectively ensuring the effectiveness of the present invention.

[0033] The elastic member 902 is a coil spring, and the inner ends of the air guide tubes 901 are fixedly connected with corresponding connecting rods 904. The sphere 903 is fixedly connected to the connecting rod 904 through the coil spring. In this embodiment, the connecting rod 904 and the elastic member 902, the sphere 903 and the elastic member 902, and the connecting rod 904 and the air guide tube 901 are fixedly connected by welding.

[0034] Corresponding sealing ridges 11 are affixed to the left and right sides of the cover 702, each extending outward. The outer ends of these sealing ridges 11 are movably abutted 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 affixed upwardly to corresponding arcuate stoppers 12. Corresponding sealing rollers 13 are rotatably mounted between these arcuate stoppers 12 and the mixing container 5. This effectively and movably secures the cover 702 in place while maintaining low friction, significantly enhancing the practical benefits of the present invention.

[0035] The sealing roller 13 is made of high-temperature resistant rubber material, and the cross-section of the arc-shaped limiting plate 12 is larger than 1 / 2 of a circle. This ensures that the sealing roller 13 does not easily deform during the sealing rotation and engagement process, and ensures the stability of the arc-shaped limiting plate 12 in limiting the sealing roller 13.

[0036] The outer edge of the annular baffle 703 is provided with a continuous transmission tooth pattern. The exhaust assembly 10 includes a set of driven gears 1001 meshingly connected to the annular baffle 703. A corresponding transmission shaft 1002 is fixedly connected between the driven gears 1001. The transmission shaft 1002 is rotatably mounted on the curved plate 3. A corresponding guide wheel 1003 is mounted in the middle of the transmission shaft 1002. At least one push rod 1004 corresponding to the sphere 903 is fixedly connected to the guide wheel 1003. During the rotation of the mixing container 5, the guide wheel 1003 rotates with it, and the push rods 1004 fixed to the guide wheel 1003 push downward one by one the spheres 903 of the one-way valve 9 that rotate through the bottom of the guide wheel 1003. This allows for the timely removal of air stored in the mixing container 5, thereby effectively further enhancing the practical effect of the present invention.

[0037] The cover door 6 is detachably mounted to the inlet and outlet of the mixing container 5 by means of a threaded connection, and a handle 14 for twisting the cover door is provided at the outer end of the cover door 6 to facilitate the opening and closing operation of the cover door 6 .

[0038] The bracket 1 includes a base plate 101 , a corresponding column 102 is fixedly connected to the base plate 101 , 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 .

[0039] A corresponding workbench 15 is fixedly mounted on the base plate 101 on the front side of the column 102 , and the fixed end of the rotary joint 701 is mounted on the workbench 15 .

[0040] The above are merely preferred embodiments of the present invention and do not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
