Description

TECHNICAL FIELD

[0001] The present application relates to the nozzle technical field, more particularly, to a double medium nozzle system and a double medium nozzle positioning device. BACKGROUND

[0002] In tobacco enterprises, double medium nozzles are used in tobacco leaf conditioning equipment of the flavoring type, the material adding type and the cylinder type. The double medium nozzles of the existing tobacco leaf conditioning equipment are mostly directly installed on the cylinder type feeding panel by using a screw. In the process production, the angle of the double medium nozzle is required to be high, and the angle of the double medium nozzle directly installed by using the screw cannot be accurately reached to the process production requirement. In addition, under the working condition of high temperature and high humidity, the fixed hole of the double medium nozzle will be enlarged after corrosion and abrasion, which causes the angle of the double medium nozzle to change and seriously affects the internal quality of the tobacco material.

[0003] In addition, the production operator cannot accurately confirm whether the angle of the double medium nozzle meets the process production requirement in the equipment inspection process. The existing angle confirmation method of the double medium nozzle is to observe the injection angle and atomization effect of the injection medium through a simulated water test, which seriously consumes working hours and reduces the production efficiency. Furthermore, according to the statistics of the angle adjustment times of the double medium nozzle of the cylinder type tobacco leaf conditioning equipment in a tobacco leaf conditioning workshop of a tobacco factory in a year, the angle of the double medium nozzle is adjusted more than 100 times in a year. In the equipment adjustment process, the professional and technical personnel need to enter the inside of the cylinder, the working space is limited, the inner wall of the cylinder is wet and slippery, there are material stirring plates or rake nails, and there are great safety hazards, and the human resources are wasted.

[0004] In summary, how to effectively solve the problems of the angle of the double medium nozzle being difficult to confirm and accurately adjusted is a problem to be solved by the technical personnel in the field at present. SUMMARY

[0041] This application discloses a dual-medium nozzle system and a dual-medium nozzle positioning device to accurately read the angle of the dual-medium nozzle and shorten the adjustment time of the dual-medium nozzle angle.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The dual-medium nozzle positioning device provided in this application is applicable to, but not limited to, tobacco processing equipment such as flavoring, feeding, and rehydration drums. It can fix the chassis to the drum feed hood of the tobacco processing equipment to achieve precise positioning and installation of the dual-medium nozzle.

[0044] Please see Figures 1-9 In one embodiment, the dual-medium nozzle positioning device provided in this application includes a chassis 100, a rotating disk 200, and a gear transmission assembly 300. The chassis 100 is provided with a scale 110 for indicating the installation angle of the dual-medium nozzle. It is understood that the scale 110 and the chassis 100 can be either a separate structure connected by a conventional fixing method or an integrated structure. The scale on the scale 110 can be raised ridges, grooves, or lines displayed in special colors; its specific form is not limited here. Furthermore, the minimum scale value of the scale 110 can be set according to the angular accuracy requirements of the rotating disk 200. The zero point of the scale 110 can be specially marked. Depending on the installation angle requirements of the rotating disk 200, when the chassis 100 is installed on equipment such as tobacco processing equipment that requires the installation of dual-medium nozzles, the zero point of the scale 110 is typically set to correspond to the zero point direction of a clock. The rotating disk 200 is rotatably mounted on the chassis 100, and the rotating disk 200 is provided with a fixing part 210 for mounting a dual-medium nozzle. The shape of the fixing part 210 can be set according to the mounting structure of the dual-medium nozzle, and is not specifically limited here. The gear transmission assembly 300 is mounted on the chassis 100 and is connected to the rotating disk 200 for transmission. The gear transmission assembly 300 is used to drive the rotating disk 200 to rotate and lock the rotating disk 200 at different angles of the rotation stroke. That is, the gear transmission assembly 300 has a self-locking function. Its operation can drive the rotating disk 200 to rotate, and when the gear transmission assembly 300 stops operating, due to the self-locking function of the gear transmission assembly 300, the rotating disk 200 is locked at the corresponding angle.

[0045] The dual-medium nozzle positioning device provided in this application drives the rotary table 200 to rotate via a gear transmission assembly 300. The gear transmission assembly 300 can lock the rotary table 200 at different angles during its rotation stroke. A scale 110 is provided on the chassis 100, allowing the installation angle of the dual-medium nozzle to be easily read from the scale 110 when it is fixed to the rotary table 200. When adjustment of the installation angle is required, the gear transmission assembly 300 is operated to rotate the rotary table 200, and the current angle of the dual-medium nozzle is observed. Once the nozzle is adjusted to the appropriate position, the operation on the gear transmission assembly 300 is stopped, and the rotary table 200 is locked at the current angle by the self-locking action of the gear transmission assembly 300. In summary, the dual-medium nozzle positioning device provided in this application allows production operators or technical personnel to accurately read the angle of the dual-medium nozzle. The nozzle angle adjustment is convenient and highly accurate, saving production costs and reducing the risk of hazardous operations.

[0046] Taking the screening and feeding process of the leaf filament production line as an example, by setting up this dual-media nozzle positioning device, the angle of the dual-media nozzle can be accurately determined during the equipment inspection before production. The angle adjustment of the dual-media nozzle is convenient, saving production costs, improving production efficiency, reducing nozzle angle adjustment time, and reducing the risk factor of dangerous operations.

[0047] In some embodiments, the gear transmission assembly 300 includes a worm gear 310 and a worm 320. The worm gear 310 is rotatably mounted on the chassis 100 and coaxially fixedly connected to the rotating disk 200; the worm 320 is rotatably mounted on the chassis 100 and meshes with the worm gear 310. The chassis 100 is provided with an operating through hole, and one end of the worm 320 extends out of the operating through hole or is located inside the chassis 100 and directly opposite the operating through hole. For details, please refer to [link to relevant documentation]. Figure 2 A worm gear slot 140 can be provided on the chassis 100, with both ends of the worm 320 positioned within the slot 140 for positioning. To limit the axial movement of the worm 320, a worm positioning screw hole 150 is provided on the chassis 100, and a positioning set screw is provided to mate with the worm positioning screw hole 150. Positioning ring grooves 321 are provided at both ends of the worm 320. When the positioning set screw is screwed into the worm positioning screw hole 150 and inserted into the positioning ring groove 321 of the worm 320, the worm 320 can be axially positioned. The worm 320 is located on the chassis 100 and coaxially fixedly connected to the rotating disk 200. By driving the worm 320 to rotate, the worm 320 drives the meshing worm wheel 310 to rotate, thereby causing the rotating disk 200 to perform circular motion, adjusting the angle of the rotating disk 200 and realizing the angle adjustment of the dual-medium nozzle on the rotating disk 200. To facilitate the driving of the worm gear 320, a hexagonal head end 322 can be provided at one end of the worm gear 320, allowing for convenient adjustment of the worm gear 320 using an Allen wrench. The gear transmission assembly 300 employs a worm wheel 310 and a worm gear 320, and worm wheel and worm gears with a precision class of 2-7 can be selected according to actual needs. The worm wheel and worm gear mechanism achieves precise nozzle angle positioning and angle self-locking function, thereby fixing the nozzle angle. In other embodiments, the gear transmission assembly 300 can also adopt a gear and rack structure combined with a locking component to achieve self-locking.

[0048] In some embodiments, a bearing 400 is provided between the worm gear 310 and the chassis 100. By providing the bearing 400, friction between the worm gear 310 and the chassis 100 is reduced during rotation, frictional wear is reduced, further facilitating the adjustment of the angle of the rotating disc 200 and extending the service life of the positioning device. Please refer to... Figure 3The worm gear 310 specifically includes a worm gear body 311 and connecting shaft portions 312 respectively located at both ends of the worm gear body 311. One end of the connecting shaft portion 312 is rotatably connected to the chassis 100 via a bearing 400, and the other end of the connecting shaft portion 312 can be connected to the rotating disk 200 via a key pin. For example, if a keyway is provided on the rotating disk 200, a key structure that mates with the keyway is provided on the corresponding connecting shaft portion 312 of the worm gear 310, which can be an integral structure with the worm gear 310. In other embodiments, the worm gear 310 and the rotating disk 200 can also be connected by screws or other conventional fixing methods.

[0049] In some embodiments, the dual-medium nozzle positioning device further includes a set screw, and a set screw through hole 120 is provided on the chassis 100. The set screw is threaded into the set screw through hole 120 to press the rotating disk 200. After the gear transmission assembly 300 adjusts the rotating disk 200 to a suitable angle and self-locks, the set screw can be further screwed into the set screw through hole 120, so that the end of the set screw can press the rotating disk 200, further realizing the locking of the rotating disk 200. That is, by combining the locking of the set screw with the self-locking of the gear transmission assembly 300, a two-stage self-locking function of the nozzle angle is realized, further improving the reliability of the nozzle angle.

[0050] In some embodiments, a plurality of set screw through holes 120 are provided on the chassis 100 along the radial direction of the rotary disk 200, and the plurality of set screw through holes 120 are distributed at intervals along the circumference of the rotary disk 200. By providing a plurality of set screw through holes 120 on the chassis 100 along the circumference, multiple set screws can be respectively engaged to press the rotary disk 200 from different positions around the circumference, making the force on the rotary disk 200 more stable and the locking more reliable.

[0051] In some embodiments, an annular groove 220 is formed on the outer circumferential surface of the rotating disk 200, and the end of the set screw is used to insert into the groove 220 to press the rotating disk 200 tightly. By providing a groove 220 on the outer circumferential surface of the rotating disk 200, the set screw can engage with the groove 220 to press the rotating disk 200 tightly when the rotating disk 200 is rotated to any angle. In addition, by providing the groove 220, space can be provided for the set screw to move in and out, so that when adjusting the angle of the rotating disk 200, the rotating disk 200 can be driven to rotate by the gear transmission assembly 300 simply by loosening the set screw without removing it. At the same time, the groove 220 can also limit the movement of the set screw.

[0052] In some embodiments, the chassis 100 includes a base 101 and a side plate 102. The base 101 is provided with a mounting portion 103 for mounting the dual-media nozzle positioning device, and a gear transmission assembly 300 is provided on the base 101. Specifically, the base 101 may be provided with a worm gear mounting groove 160 for mounting a worm gear 310, so as to be rotatably connected to the connecting shaft portion 312 at one end of the worm gear 310. The side plate 102 is annular, with one end of the side plate 102 connected to the base 101, and a rotating disk 200 provided at the other end of the side plate 102. The mounting portion 103 may specifically be a mounting hole. For example, taking the dual-media nozzle positioning device as an example for use in screening equipment, the chassis 100 is mounted to the feed hood of the screening feed roller by a screw that mates with the mounting hole. The side plate 102 cooperates with the rotating disk 200 to enable the installation of the rotating disk 200 and to form a cavity in which the gear transmission assembly 300 is installed, thus providing protection for the gear transmission assembly 300. In other embodiments, the chassis 100 may also adopt other structures such as a frame structure.

[0053] In some embodiments, the center of the chassis 100 and the center of the rotating disk 200 are respectively provided with a connected chassis medium channel 130 and a rotating disk medium channel 230. When the gear transmission assembly 300 includes a worm gear 310, the center of the worm gear 310 is also provided with a worm gear medium channel. The rotating disk medium channel 230, the worm gear medium channel, and the chassis medium channel 130 provide a medium flow channel from one side of the dual-medium nozzle positioning device rotating disk 200 to the opposite side to meet the medium flow requirements. It is understood that the rotating disk medium channel 230, the worm gear medium channel, and the chassis medium channel 130 should be sealed to prevent medium leakage.

[0054] In some embodiments, the rotary dial 200 is provided with a pointer 240 for cooperating with the dial 110. In order to more clearly indicate the angle of the dual-medium nozzle, the rotary dial 200 is provided with a pointer 240, the position of which is matched with the position of the fixing part 210 for mounting the dual-medium nozzle, so that when the dual-medium nozzle is fixed on the rotary dial 200, the position of the pointer 240 corresponds to the position of the pointer 240 on the dial 110, so that the angle of the dual-medium nozzle can be read intuitively.
