Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a servo speed reducer for stirring ice cream machines. Background Technology

[0002] Ice cream is a frozen beverage made from drinking water, milk and dairy products, egg products, fruit products, soy products, sugar, and edible vegetable oil as the main raw materials, with or without food additives and food fortifiers. It is produced through processes such as mixing, sterilization, homogenization, aging, freezing, and hardening, resulting in an expanded volume. During the ice cream processing, the mixing equipment uses a speed reducer to adjust the speed of the mixing mechanism.

[0003] Chinese Utility Model Patent Publication No. CN206592487U discloses a food mixing reducer, comprising a housing and a worm gear and worm shaft rotatably mounted within the housing. The inner wall of the housing has chambers that respectively clearance-fit the worm shaft and worm gear. The outer wall of the housing is cylindrical at the worm gear mounting position. The housing has a power input hole and a pair of through power output holes, each equipped with a sealing device. The worm gear and worm shaft are respectively positioned perpendicular to their axes. The worm gear is hollow and has a through hole coaxial with the power output hole, the output end of which is a square hole. The worm shaft is rotatably mounted within the housing via angular contact bearings and double-row angular contact bearings. It has the following advantages: a reasonable housing structure, a compact overall design, and provides a large axial load; it can withstand the axial force generated by mixing and has a long service life.

[0004] While the aforementioned speed reducer can extend its service life during use, the motor in the speed reducer uses a three-phase asynchronous motor as the power source, which is not only larger in size but also less efficient and cannot adjust the reduction ratio. Furthermore, the speed reducer does not have a dustproof mechanism, so dust can easily enter the speed reducer during operation, causing corrosion to the internal components and reducing the dustproof effect of the speed reducer. Therefore, we propose a servo speed reducer for ice cream machine mixing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a servo reducer for stirring ice cream machines, thereby solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a servo reducer for stirring in an ice cream machine, comprising a body assembly, a mounting assembly, and a fixing assembly, wherein the body assembly includes a servo motor, and a worm gear is fixedly mounted on the output shaft of the servo motor; The mounting assembly includes a fixed housing, and a worm gear is rotatably connected to the inner wall of the fixed housing; The fixing assembly includes a guide wheel, the outer wall of which is rotatably connected to a steel wire rope. A connecting ring is located at the end of the servo motor furthest from the output shaft. A fixing plate is fixedly mounted on the outer wall of the connecting ring. An installation groove is formed in the middle of the fixing plate. A retaining spring and a movable pin are respectively provided on the inner wall of the installation groove. A positioning rod is rotatably connected to one end of the movable pin, and a locking block is provided at the other end of the movable pin. Locking holes are formed on both sides of the locking block. A compression ring is fixedly sleeved at the end of the movable pin located on the inner wall of the installation groove. A steel wire rope is connected to the bottom end of the positioning rod. A filter screen is fixedly mounted on the outer wall of the locking block, and a rotating rod is fixedly mounted on the outer wall of the servo motor.

[0007] Through the above technical solution, the fixed components, guide wheels, positioning rods, rotating rods, and wire rope structure allow the user to rotate one positioning rod during use, which in turn drives the other positioning rod to rotate via the wire rope. This facilitates the user's removal of both positioning rods to install the filter and the compression ring. This ensures that when the servo motor generates heat and the fan generates cool air for cooling, dust in the air is filtered out, improving the dustproof effect of the reducer during heat dissipation. It also facilitates the user's removal and installation of the filter, increasing the user's maintenance efficiency for the reducer.

[0008] Preferably, there are two positioning rods, and the other end of the wire rope is connected to the top of the other positioning rod.

[0009] With the above technical solution, the two wire rope structures allow users to rotate one positioning rod with two fingers when assembling or disassembling the filter screen. This rotation of both positioning rods can drive the other positioning rod to rotate, thus enabling the filter screen to be quickly installed in the connecting ring. This facilitates user operation and improves the practicality of the reducer and the user's work efficiency.

[0010] Preferably, the outer wall of the compression ring is slidably connected to the inner wall of the mounting groove, and the diameter of the locking hole is adapted to the diameter of the movable pin. The locking block is fixedly connected to the fixing plate through the movable pin.

[0011] Through the above technical solution, the movable pin and locking hole structure allows the filter screen to be fixed by the movable pin during operation, thereby preventing the filter screen from detaching from the connecting ring due to the vibration force generated by the reducer during operation, and thus improving the stability of the filter screen during operation.

[0012] Preferably, the end of the servo motor away from the output shaft is fixedly fitted with a protective shell, and the outer wall of the protective shell is provided with heat dissipation grooves, the position of which corresponds to the position of the filter screen.

[0013] Through the above technical solution, the protective shell and heat dissipation trough structure enable the reducer to draw in outside air during operation via a fan. After being drawn in and filtered through a filter, the clean, cool air is sent to the servo motor for heat dissipation, thereby accelerating the heat dissipation efficiency of the servo motor and ensuring the normal operation of the reducer.

[0014] Preferably, there are two guide wheels, and the outer walls of the two guide wheels are respectively rolledly connected to the outer wall of a steel wire rope.

[0015] Through the above technical solution, the guide wheel and wire rope structure are designed so that the guide wheel can be used to position and tension the wire rope, thereby ensuring that the direction of force on the wire rope will not change when it is pulled. This ensures that when the user moves the positioning rod, the other positioning rod can also drive the other movable pin to move horizontally, thus ensuring that the user can disassemble and assemble the filter screen.

[0016] Preferably, the outer wall of the positioning rod has a limiting hole, and the inner wall of the limiting hole is rotatably connected to the outer wall of the rotating rod.

[0017] Through the above technical solution, the positioning rod is limited and positioned by the setting of the limiting hole and the rotating rod structure during the rotation process. Therefore, no matter which direction the positioning rod rotates, it will not disengage from the servo motor. This makes it convenient for users to reinstall the filter after removing it, thus ensuring that the subsequent use of the reducer will not be affected.

[0018] Preferably, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and the outer wall of the fixed housing is fixedly assembled with the outer wall of the servo motor. The gearbox structure adopted by the worm gear and worm wheel is a transmission pair with high-precision dimensional grinding and secondary precision rolling.

[0019] Through the above technical solution, by setting a fixed shell and servo motor structure, the operation of the servo motor output shaft drives the worm gear to rotate, thereby enabling the reducer to complete the transmission operation during operation. This allows the reducer to complete the operation more efficiently with the same power as a three-phase asynchronous synchronous motor, resulting in higher energy utilization. The reduction ratio can also be adjusted, and the size is smaller. During operation, the overall structure of the servo motor and fixed shell is more unified, effectively reducing noise generation and thus improving the practicality of the reducer.

[0020] Compared with the prior art, the present invention provides a servo reducer for stirring in an ice cream machine, which has the following advantages: 1. This servo reducer for ice cream machine mixing, through its body components, worm gear, worm wheel, servo motor, and fixed shell structure, utilizes the servo motor as a power source during operation. Compared to a three-phase asynchronous motor, it is smaller in size and has higher operating efficiency. The internal reduction mechanism is adjusted by changing the power of the servo motor, making it easier for users to operate. The overall structure of this reducer is more unified, reducing noise generation and thus improving its practicality.

[0021] 2. The servo reducer for stirring in this ice cream machine, through its fixed components, guide wheels, positioning rods, rotating rods, and wire rope structure, allows the reducer to filter dust from the air during operation. This effectively prevents dust from contacting the internal components of the reducer during the servo motor's heat dissipation process. It also facilitates the user's disassembly and assembly of the filter, thereby improving the reducer's dustproof effect and the user's maintenance efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5As shown, the present invention provides a servo reducer for stirring an ice cream machine, including a body assembly 1, a mounting assembly 2, and a fixing assembly 3. The body assembly 1 includes a servo motor 101, and a worm gear 102 is fixedly mounted on the output shaft of the servo motor 101. Mounting assembly 2 includes a fixed housing 201, and a worm gear 202 is rotatably connected to the inner wall of the fixed housing 201; The fixed assembly 3 includes a guide wheel 301, with a steel wire rope 304 rotatably connected to the outer wall of the guide wheel 301. A connecting ring 305 is provided at the end of the servo motor 101 away from the output shaft. A fixed plate 307 is fixedly mounted on the outer wall of the connecting ring 305. An installation groove 308 is provided in the middle of the fixed plate 307. A retaining spring 309 and a movable pin 310 are respectively provided on the inner wall of the installation groove 308. A positioning rod 302 is rotatably connected to one end of the movable pin 310. A locking block 312 is provided at the other end of the movable pin 310. Locking holes 313 are provided on both sides of the locking block 312. A compression ring 311 is fixedly sleeved at the end of the movable pin 310 located on the inner wall of the installation groove 308. A steel wire rope 304 is connected to the bottom end of the positioning rod 302. A filter screen 306 is fixedly mounted on the outer wall of the locking block 312. A rotating rod 303 is fixedly mounted on the outer wall of the servo motor 101.

[0026] The advantage is that, through the structure of the fixed component 3, guide wheel 301, positioning rod 302, rotating rod 303, and wire rope 304, the user can rotate one positioning rod 302 during use, which in turn drives the other positioning rod 302 to rotate via the wire rope 304. This facilitates the user to remove the two positioning rods 302 to install the filter screen 306 and the compression ring 311. This ensures that when the servo motor 101 generates heat and the fan generates cold air to dissipate the heat during operation, dust in the air is filtered out, thereby improving the dustproof effect of the reducer during heat dissipation. It also facilitates the user's disassembly and assembly of the filter screen 306, improving the user's maintenance efficiency of the reducer.

[0027] Specifically: there are two positioning rods 302, and the other end of the wire rope 304 is connected to the top of the other positioning rod 302.

[0028] The advantage is that, through the two steel wire ropes 304 structure, when the user is assembling or disassembling the filter screen 306, one of the positioning rods 302 can be turned by two fingers, so that when the two positioning rods 302 are turned, the other positioning rod 302 can be turned. This achieves the effect of quickly installing the filter screen 306 in the connecting ring 305, which facilitates the user's operation and improves the practicality of the reducer and the user's work efficiency.

[0029] Specifically: the outer wall of the compression ring 311 is slidably connected to the inner wall of the mounting groove 308, and the diameter of the locking hole 313 is adapted to the diameter of the movable pin 310. The locking block 312 is fixedly connected to the fixing plate 307 through the movable pin 310.

[0030] The advantage is that, through the structure of the movable pin 310 and the locking hole 313, the filter screen 306 is fixed by the movable pin 310 during operation, thereby preventing the filter screen 306 from detaching from the connecting ring 305 due to the vibration force generated by the reducer during operation, thus improving the stability of the filter screen 306 during operation.

[0031] Specifically: The end of the servo motor 101 away from the output shaft is fixedly equipped with a protective shell. The outer wall of the protective shell is provided with heat dissipation grooves, and the position of the heat dissipation grooves corresponds to the position of the filter screen 306.

[0032] The advantage is that, through the protective shell and heat dissipation trough structure, the reducer can draw in outside air during operation using a fan. After being drawn in and filtered through the filter screen 306, the clean, cool air is sent to the servo motor 101 for heat dissipation, thereby accelerating the heat dissipation efficiency of the servo motor 101 and ensuring the normal operation of the reducer.

[0033] Specifically: There are two guide wheels 301, and the outer walls of the two guide wheels 301 are respectively connected to the outer wall of a steel wire rope 304 in a rolling manner.

[0034] The advantage is that, through the structure of the guide wheel 301 and the wire rope 304, the guide wheel 301 can be used to position and tension the wire rope 304, thereby ensuring that the direction of force on the wire rope 304 will not change when it is pulled. This ensures that after the user moves the positioning rod 302, the other positioning rod 302 can also drive the other movable pin 310 to move horizontally, thus ensuring that the user can disassemble and assemble the filter screen 306.

[0035] Specifically: a limiting hole is provided on the outer wall of the positioning rod 302, and the inner wall of the limiting hole is rotatably connected to the outer wall of the rotating rod 303.

[0036] The advantage is that, through the structure of the limiting hole and the rotating rod 303, the positioning rod 302 is limited and positioned by the rotating rod 303 during rotation. Therefore, no matter which direction the positioning rod 302 rotates, it will not disengage from the servo motor 101. This makes it convenient for the user to reinstall the filter 306 after removing it, thus ensuring that the subsequent use of the reducer will not be affected.

[0037] Specifically: the outer wall of the worm 102 meshes with the outer wall of the worm wheel 202, and the outer wall of the fixed housing 201 is fixedly assembled with the outer wall of the servo motor 101. The gearbox structure adopted by the worm 102 and the worm wheel 202 is a transmission pair with high precision grinding and secondary precision rolling.

[0038] The advantages are that, through the structure of the fixed housing 201 and the servo motor 101, the output shaft of the servo motor 101 drives the worm gear 102 to rotate, thereby enabling the reducer to complete the transmission operation during operation. This allows the reducer to complete the operation more efficiently with the same power as a three-phase asynchronous synchronous motor, resulting in higher energy utilization. The reduction ratio can also be adjusted, and the size is smaller. Furthermore, during operation, the overall structure of the servo motor 101 and the fixed housing 201 is more unified, effectively reducing noise generation and thus improving the practicality of the reducer.

[0039] Working principle: When installing the filter 306, the user can use two fingers to rotate one positioning rod 302. At this time, the positioning rod 302 will drive the other positioning rod 302 to rotate in the opposite direction through the wire rope 304, so that both movable pins 310 are disengaged from the locking hole 313. This makes it easy for the user to install and remove the filter 306. The installation of the filter 306 can filter the air and prevent dust from entering the reducer and causing corrosion or damage to the components, thereby improving the dustproof effect of the reducer and the user's maintenance efficiency. During operation, the reducer uses the servo motor 101 to drive the worm gear 202 to rotate, thereby realizing the transmission operation. The user can adjust the reduction ratio by adjusting the power of the servo motor 101, which is suitable for different production scenarios. At the same time, the connection and sealing of the servo motor 101 and the worm gear 202 reduce the generation of noise, thereby improving the practicality of the reducer.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
