Description

Technical Field

[0001] The present invention relates to the technical field of discharging nozzles, in particular to a 90-degree self-stirring and automatic sealing discharging nozzle. Background Art

[0002] The demand for beverages such as coffee, soy milk, and milk tea in daily dining places is increasing, and as a result, the number of beverage mixing machines has increased. Common beverage mixing machines mainly include a machine base, a material box, a right-angle discharge pipe, a discharge hopper, a mounting frame, and a stirring mechanism. The basic working method is that the right-angle discharge pipe transports the powdered particles of the beverage to the discharge nozzle, and then the powdered particles are evenly distributed into the cup through the discharge nozzle, and water is added to make the beverage.

[0003] In this type of beverage dispensing machine, a spiral conveyor is usually used to transport powdered particles, but the fixed connection method means that the discharge nozzle can only discharge materials according to the fixed position after installation, which is not convenient for changing the discharge position and is not conducive to adapting to a changing use environment. Since the materials in the beverage dispensing machine are powdered and the beverage dispensing machine is often used frequently, these powdered materials often get clogged in the right-angled discharge pipe inside the discharge nozzle. After the blockage occurs, it needs to be disassembled and cleaned, which is not conducive to improving the beverage dispensing efficiency and affecting the normal use of the beverage dispensing machine. These right-angled discharge pipes are usually straight-through pipe structures. The straight-through pipe discharge method is prone to cause beverage particles to accumulate and agglomerate, affecting the quality of the beverage in the subsequent dispensing process. The right-angled discharge pipe outlet of the discharge nozzle of some beverage dispensing machines lacks a closing function, and the unsealed outlet will leak material, and the open outlet will have pollution sources in the external environment contaminating the beverage particles in the right-angled discharge pipe during idle time, which has an adverse effect on the safety and quality of the beverage.

[0010] Preferably, a right-angled discharge pipe is provided between the outer wall of the transmission shaft bracket and the inner wall of the shell, and the right-angled discharge pipe is respectively connected to the top inlet and the bottom outlet of the shell.

[0011] Preferably, the right-angle transmission mechanism includes a first transmission shaft, a first bevel gear, a second bevel gear and a second transmission shaft. The first transmission shaft is connected to the sealing gasket of the vertical section of the transmission shaft bracket, and the end of the first transmission shaft is rotatably connected to the inner wall of one side of the outer shell. The end of the first transmission shaft is fixedly connected to the first bevel gear. A triangular sleeve is provided on the side wall of the first end of the first transmission shaft. The second transmission shaft is connected to the sealing gasket of the horizontal section of the transmission shaft bracket, and the bottom end of the second transmission shaft is rotatably connected to the center of the bottom end of the outer shell. The top of the second transmission shaft is fixedly connected to the second bevel gear, and the first bevel gear and the second bevel gear are meshed.

[0012] Preferably, two symmetrically arranged inverted L-shaped stirring paddles are fixedly connected to the side wall of the second transmission shaft below the transmission shaft bracket, and a shifting rod is fixedly connected to the side wall of the second transmission shaft between the two stirring paddles.

[0013] Preferably, the discharging mechanism includes a discharging wheel and a closed blade. The discharging wheel is sleeved on the bottom of the second transmission shaft, and the closed blade is fixedly connected to the bottom end of the second transmission shaft. The closed blade is located below the center of the bottom end of the outer shell. The closed blade is a symmetrical structure with hollowed-out sides, and the outer diameter of the closed blade is the same as the outer diameter of the bottom end of the outer shell.

[0014] Preferably, the discharging wheel includes a discharging impeller and a groove, a sleeve is sleeved on the bottom side wall of the second transmission shaft, and two discharging impellers are symmetrically arranged on the side wall of the sleeve. The discharging impeller is a torsional structure, and the top of the discharging impeller is a sloped surface. A groove is opened on the top of one of the discharging impellers, and the groove is adapted to the shift rod. Scrapers are provided at both ends of the bottom of each discharging impeller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention provides a shell and a spiral feeding rod, and the shell integrates functions such as conveying reversing and stirring and unloading. The shaft sleeve opened at the head end of the first transmission shaft can cooperate with the spiral feeding rod below the material box, and the spiral feeding rod and the shell are connected by the shaft sleeve. The connecting part between the shell and the material box is threaded, and the direction of the discharge port can be changed by rotating the shell. It is adaptable to different cups, and the material is conveyed in a spiral conveying manner, which also has a stirring function. The granular material can be fully stirred during the material conveying to ensure the uniformity of the material discharge, reduce the possibility of material adhesion, and improve the accuracy of the material conveying amount each time.

[0017] The present invention provides a stirring paddle and a discharge wheel, and the spiral feeding rod drives the stirring paddle to rotate at the same time. During the discharge process, the stirring paddle rotates in a circle around the center of the second transmission shaft, which can effectively stir the material in the right-angle discharge pipe, which can not only promote the movement of the material and facilitate the falling of the material, but also prevent the material from being blocked in the right-angle discharge pipe. The two discharge impellers on the discharge wheel can change the falling mode of the material in the right-angle discharge pipe to spiral falling. The spiral descending mode can fully stir the material and is more conducive to dispersing granular materials, so that the material is not easy to stick or agglomerate, thereby improving the quality of the subsequent finished beverages of the beverage mixing machine.

[0018] The present invention provides a closed blade, which cooperates with the discharge impeller. When the discharge nozzle discharges materials, the discharge impeller and the closed blade rotate synchronously, and the closed blade coincides with the discharge impeller, so that the material can pass through the discharge port normally. After the discharge is completed, the lever is disengaged from the groove, and the discharge wheel stops rotating while the closed blade continues to rotate. After the motor reverses for two seconds, the closed blade completely covers the bottom outlet of the discharge wheel, thereby realizing the sealing function of the discharge port, preventing the material discharged from the discharge port from being scattered at will, and preventing the material from being polluted by external pollution sources and affecting the quality of the material. The scraper can scrape off the material remaining on the top of the closed blade as the closed blade is reset during each discharging process, which helps to increase the service life of the discharge nozzle and reduce the number of cleaning or maintenance times.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-10A 90-degree self-stirring automatic sealing discharging nozzle includes a material box 1 and a mounting frame 101. Granular material is contained in the material box 1. Discharging ports are opened at both ends of the bottom of the material box 1. Slots 103 are symmetrically opened on both side walls of the bottom of the material box 1. Threads 104 are provided on the outer walls of the two discharging ports. The bottom of the material box 1 is movably connected to the mounting frame 101. The bottom of the material box 1 is rotatably connected to a stirring mechanism 3. One end of the material box 1 is rotatably connected to an L-shaped shell 4. A discharging port 401 is opened at the bottom of the shell 4. A right-angle transmission mechanism 7 is provided on the top of the shell 4. A discharging mechanism 11 is provided at the bottom of the shell 4. The other end of the material box 1 is threadedly connected to a screw locking cap 2. Beverage dispensing machines are commonly used in various catering establishments. The powdered or granular solid beverages contained in the material box 1 are generally quantitatively transported to the outside of the beverage dispensing machine by an automatic conveying device, and fall into the cup through the discharge nozzle for the next step of dispensing. The material in the material box 1 is usually replenished after a period of use, and during use, because it does not need to be cleaned or replaced, it can be regarded as continuous operation. Therefore, the present invention adopts a spiral conveying method to transport the material. At the same time, the spiral conveying also has a stirring function, which can fully stir the granular material during material transportation to ensure the uniformity of material feeding, reduce the possibility of material adhesion, and improve the accuracy of each material delivery amount. The mounting bracket 101 is convenient for positioning the material box 1 and the stirring mechanism 3, and can also facilitate the installation and fixation of the stirring mechanism 3. The stirring mechanism 3 is usually arranged inside the body of the beverage dispensing machine, and the discharge nozzle is installed outside the beverage dispensing machine for convenience. In order to receive materials in the cup, the outlet end of the stirring mechanism 3 is connected to the body of the beverage dispensing machine, so that the outer shell 4 of the discharge nozzle is connected to the stirring mechanism 3 to form a whole. The right-angle transmission mechanism 7 can convert the material conveying direction. By rotating the outer shell 4, the direction of the discharge port 401 can be adjusted at any time to achieve the purpose of adjusting the material conveying position, which can adapt to different types of cups. The discharge mechanism 11 is different from the traditional straight-through pipe discharge method. The stirring paddle 9 and the specially structured discharge impeller 12 can disperse and convey the material accumulated in the right-angle discharge pipe 8, which can effectively reduce the phenomenon of material accumulation and improve the quality of the final beverage product. The screw locking cap 2 cooperates with the thread 104 to seal one end of the motor interface 301 to prevent material from overflowing into the interior of the beverage dispensing machine and affecting normal operation. The material conveyed from the material box 1 through the stirring mechanism 3, the right-angle transmission mechanism 7, and the discharge mechanism 11 finally enters the cup through the discharge port 401.

[0032] As a technical optimization solution of the present invention, the mounting frame 101 has a U-shaped structure, and buckles 102 are symmetrically arranged on the inner wall of the mounting frame 101, and the positions of the buckles 102 correspond one-to-one with the slots 103. The mounting frame 101 mainly cooperates with the installation of the material box 1 and the stirring mechanism 3, so that the material box 1 and the stirring mechanism 3 are stably fixed inside the beverage dispensing machine. To facilitate assembly and disassembly, an easy-to-operate snap-on installation method is adopted.

[0033] As a technical optimization solution of the present invention, the stirring mechanism 3 includes a motor interface 301 and a spiral feeding rod 302. A rubber ring 303 is slidably connected to the discharge port at the bottom of the material box 1 away from the end of the shell 4. The size of the rubber ring 303 is adapted to the discharge port. One end of the spiral feeding rod 302 is fixedly connected to the center of the rubber ring 303. The other end of the spiral feeding rod 302 is a triangular structure. The side of the rubber ring 303 away from the spiral feeding rod 302 is fixedly connected to the motor interface 301. The motor interface 301 is a hollow cylindrical structure, and a stopper 304 is provided on the inner wall of the motor interface 301. The rubber ring 303 can seal the discharge port. The center of the rubber ring 303 adopts a solid metal lining to facilitate the fixed connection between the spiral feeding rod 302 and the motor interface 301. The motor interface 301 can be connected to the motor output shaft. The stopper 304 facilitates the positioning and clamping of the motor output shaft.

[0034] As a technical optimization solution of the present invention, the outer shell 4 is fixedly connected by screws 5, and an L-shaped sealing groove 402 is provided on the inner wall of the outer shell 4. A transmission shaft bracket 6 is clamped in the sealing groove 402. The horizontal and vertical sections of the transmission shaft bracket 6 are provided with circular through holes, and a sealing gasket 601 is movably connected in the circular through hole. Since the materials contained in the material box 1 are powdery or granular, these materials are prone to flying during transportation. In order to prevent the scattered materials from affecting the normal operation of the equipment, the sealing groove 402 on the inner wall of the outer shell 4 divides the outer shell 4 into two parts, namely the transmission part and the material conveying part. The two parts are separated by the transmission shaft bracket 6 installed in the sealing groove 402 and sealed with a sealing gasket 601. When using the beverage mixing machine, it can ensure that the material conveyed in the right-angle discharge pipe 8 cannot enter the interior of the right-angle transmission mechanism 7, and will not affect the normal operation of the transmission shaft of the right-angle transmission mechanism 7.

[0035] As a technical optimization solution of the present invention, a right-angled feed pipe 8 is provided between the outer wall of the drive shaft bracket 6 and the inner wall of the housing 4. The right-angled feed pipe 8 connects to the top inlet and the bottom outlet 401 of the housing 4. The right-angled feed pipe 8 is used to convey the material, allowing the material to enter the interior of the housing 4 through the stirring mechanism 3 and change the conveying direction through the right-angled feed pipe 8.

[0036] As a technical optimization solution of the present invention, the right-angle transmission mechanism 7 includes a first transmission shaft 701, a first bevel gear 702, a second bevel gear 703 and a second transmission shaft 704. The first transmission shaft 701 is connected to the sealing gasket 601 of the vertical section of the transmission shaft bracket 6. The end of the first transmission shaft 701 is rotatably connected to the inner wall of one side of the outer shell 4. The end of the first transmission shaft 701 is fixedly connected to the first bevel gear 702. A triangular sleeve 705 is provided on the side wall of the first end of the first transmission shaft 701. The second transmission shaft 704 is connected to the sealing gasket 601 of the horizontal section of the transmission shaft bracket 6. The bottom end of the second transmission shaft 704 is rotatably connected to the center of the bottom end of the outer shell 4. The top of the second transmission shaft 704 is fixedly connected to the second bevel gear 703. The first bevel gear 702 and the second bevel gear 703 are meshed with each other. When the right-angle transmission mechanism 7 is in use, the triangular end of the spiral feeding rod 302 is connected to the shaft sleeve 705, and the motor output shaft is connected to the motor interface 301. Starting the motor to rotate forward can drive the spiral feeding rod 302 to rotate counterclockwise, and the first transmission shaft 701 and the first bevel gear 702 will then rotate counterclockwise, and the second bevel gear 703 and the second transmission shaft 704 will rotate clockwise. Conversely, reversing the motor can drive the second bevel gear 703 and the second transmission shaft 704 to rotate counterclockwise. The right-angle transmission mechanism 7 can realize the reversal of power transmission, so that the material output of the stirring mechanism 3 can change with the change of the direction of the discharge port 401, which is beneficial to improving the applicability of the discharge nozzle.

[0037] As a technical optimization solution of the present invention, two symmetrically arranged inverted L-shaped stirring paddles 9 are fixedly connected to the side wall of the second transmission shaft 704 below the transmission shaft bracket 6, and a shift lever 10 is fixedly connected to the side wall of the second transmission shaft 704 between the two stirring paddles 9. The L-shaped stirring paddles 9 are distributed in the right-angle discharge pipe 8 and can rotate with the rotation of the second transmission shaft 704. During the discharge process, the stirring paddles 9 rotate in a circle around the center of the second transmission shaft 704, which can effectively stir the material in the right-angle discharge pipe 8, promote the movement of the material, facilitate the falling of the material, and prevent the material from being blocked in the right-angle discharge pipe 8. The shift lever 10 is used to drive the discharge wheel 111 to rotate during the rotation of the second transmission shaft 704.

[0038] As a technical optimization solution of the present invention, the discharge mechanism 11 includes a discharge wheel 111 and a closed blade 112. The discharge wheel 111 is sleeved on the bottom of the second transmission shaft 704. The closed blade 112 is fixedly connected to the bottom end of the second transmission shaft 704, and the closed blade 112 is located below the center of the bottom end of the housing 4. The closed blade 112 is a symmetrical structure with two sides hollowed out. The outer diameter of the closed blade 112 is the same as the outer diameter of the bottom end of the housing 4. The discharge mechanism 11 is coaxially driven with the second transmission shaft 704, wherein the discharge wheel 111 is sleeved on the second transmission shaft 704. The discharge wheel 111 can be driven to rotate by the shifting rod 10 and stops rotating when the shifting rod 10 is lost. The hollow portion of the closed blade 112 is the same shape and size as the bottom opening of the discharge wheel 111. Since the closed blade 112 and the discharge wheel 111 are both symmetrical structures, the closed blade 112 can close the bottom outlet of the discharge wheel 111 after rotating to the appropriate position.

[0039] As a technical optimization solution of the present invention, the discharging wheel 111 includes a discharging impeller 12 and a groove 121. The bottom side wall of the second transmission shaft 704 is sleeved with a sleeve 122. Two discharging impellers 12 are symmetrically arranged on the side wall of the sleeve 122. The discharging impeller 12 is a torsional structure. The top of the discharging impeller 12 is a sloped surface. A groove 121 is opened on the top of one of the discharging impellers 12. The groove 121 is adapted to the lever 10. Scrapers 13 are arranged at both ends of the bottom of each discharging impeller 12. During the discharge process of the discharge nozzle, the two discharge impellers 12 can change the falling mode of the material in the right-angle discharge tube 8 to spiral falling. The spiral descending mode is conducive to dispersing granular materials, making it difficult for the materials to stick or clump together, thereby improving the quality of the subsequent finished beverages of the beverage brewing machine. When the lever 10 rotates clockwise with the second transmission shaft 704, the lever 10 can be rotated to enter the groove 121 and drive the discharge wheel 111 to rotate clockwise, and the closed blade 112 rotates synchronously with the lever 10. At this time, the closed blade 112 coincides with the bottom solid part of the discharge wheel 111, and the material delivered from the material box 1 can be smoothly delivered to the outside of the shell 4 from the discharge port 401. When the motor is reversed, the lever 10 and the groove The groove 121 is disengaged, and the discharge wheel 111 stops rotating while the closing blade 112 continues to rotate. After the motor reverses for two seconds, the closing blade 112 completely covers the bottom outlet of the discharge wheel 111, and the closing function of the discharge port 401 can be realized. After the discharge port 401 is closed, materials will accumulate on the top of the closing blade 112. If not handled, after a period of time, it may get stuck in the gap between the closing blade 112 and the discharge impeller 12, affecting the normal operation of the closing blade 112. The scraper 13 can scrape off the material remaining on the top of the closing blade 112 as the closing blade 112 is reset during each discharging process, which helps to increase the service life of the discharge nozzle and reduce the number of cleaning or maintenance.

[0040] When the present invention is in use, the operator inserts the spiral feeding rod 302 into the discharge port at the bottom of the material box 1 until the rubber ring 303 slides into the discharge port outlet, and then inserts the screw locking cap 2 into the motor interface 301 to connect the thread 104 and tighten the screw locking cap 2. At this time, the triangular structure at one end of the spiral feeding rod 302 can pass through the outside of the beverage dispensing machine body, and then the outer shell 4 can be moved as a whole close to the triangular structure and the shaft sleeve 705 can be connected to the triangular end of the spiral feeding rod 302 to complete the installation of the discharge nozzle. At this time, the outlet direction of the discharge port 401 can also be adjusted by rotating the outer shell 4. After the adjustment is completed, the output shaft of the motor is connected to the motor interface 301 and the machine is started. The motor rotates forward to drive the spiral feeding rod 302 to rotate counterclockwise, and the spiral feeding rod 302 drives the material in the material box 1 to be transported along the right-angle discharge pipe 8. At the same time, the first transmission shaft 701 and the first bevel gear 702 rotate counterclockwise, and the second bevel gear 703 and the second transmission shaft 704 rotate clockwise. The stirring paddle 9 rotates in a circle around the center of the second transmission shaft 704 to stir the material. The lever 10 is connected to the groove 121 to drive the discharge impeller 12 and the closed blade 112 to rotate synchronously. At this time, the closed blade 112 coincides with the solid part of the bottom of the discharge wheel 111, and the material transported out of the material box 1 can be smoothly transported from the discharge port 401 to the outside of the discharge nozzle.

[0041] After completing one feeding, the motor reverses the spiral feeding rod 302 to rotate clockwise, driving the first transmission shaft 701 and the first bevel gear 702 to rotate clockwise, while the second bevel gear 703 and the second transmission shaft 704 rotate counterclockwise. At this time, the lever 10 disengages from the groove 121, the discharge wheel 111 loses power and stops rotating, and the closing blade 112 continues to rotate to the bottom opening of the discharge wheel 111 to close it. After the motor reverses for two seconds, the closing blade 112 completely covers the bottom outlet of the discharge wheel 111. During the next feeding, as the closing blade 112 resets, the scraper 13 can scrape off the material remaining on the top of the closing blade 112.

[0042] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.

[0043] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
