Description

Technical Field

[0001] This utility model relates to the field of ice cream machine technology, and specifically to a transmission device and an ice cream machine. Background Technology

[0002] Ice cream machines are commonly used to make ice cream, smoothies, and other similar products, and can also be used to churn and crush certain ingredients. Ice cream machines typically include a transmission mechanism to drive the mixing blades to rotate and move vertically.

[0003] For example, the utility model patent with patent publication number CN222208936U discloses a transmission structure for an ice cream machine. This prior art transmission structure is vertically set and uses a lifting and lowering method to transmit power, so as to drive the stirring blade to rotate and move vertically up and down. Its overall structure is relatively tall and requires a large space. Moreover, the prior art transmission structure is composed of a motor, a motor shaft, a planetary gearbox, a lifting component, and a multi-stage gear transmission component, which is very complex and costly.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a transmission device and an ice cream machine. By arranging the transmission device horizontally, its overall height can be reduced, thus occupying less space.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: A transmission device includes a first fixed base, an output shaft, a guide column, a gearbox assembly, a second fixed base, and a drive assembly. The first and second fixed bases are horizontally spaced apart. The guide column is fixed between the first and second fixed bases. The gearbox assembly and the drive assembly are slidably mounted on the guide column. The first end of the output shaft is movably mounted on the second fixed base, and the second end of the output shaft passes through the gearbox assembly and connects to the output end of the drive assembly. A threaded sleeve is fixed on the second fixed base. The input end of the gearbox assembly is connected to the output shaft, and the output end of the gearbox assembly has a stud, which is threadedly connected to the threaded sleeve. In this configuration, during operation, the drive assembly drives the output shaft to rotate. Under the action of the gearbox assembly, the rotation of the output shaft drives the stud to rotate. Because the stud and the threaded sleeve are threadedly connected, the rotation of the stud causes threaded movement with the threaded sleeve, allowing the gearbox assembly and the drive assembly to slide, and causing the output shaft to extend and retract horizontally relative to the second fixed base, achieving horizontal extension and retraction while the output shaft rotates. Furthermore, by arranging the transmission device horizontally, its overall height can be reduced, thus occupying less space.

[0007] According to the above scheme, the drive assembly includes a large pulley, a synchronous belt, a small pulley, a motor bracket, and a motor. The motor bracket is slidably mounted on a guide post, the motor is mounted on the motor bracket, the output end of the motor is driven and connected to the small pulley, the large pulley is engaged and connected to the second end of the output shaft, and the synchronous belt is wound around the small pulley and the large pulley. With this configuration, when the motor is working, it drives the small pulley to rotate at high speed, and under the action of the synchronous belt, it drives the large pulley and the output shaft to achieve decelerated rotation.

[0008] According to the above scheme, the large pulley is provided with a flat hole, and the second end of the output shaft is provided with a flat part, which is inserted into the flat hole. This arrangement allows the large pulley and the second end of the output shaft to be locked together, thus enabling the output shaft to rotate when the large pulley rotates.

[0009] According to the above scheme, the gearbox assembly includes a planetary gearbox housing, a planetary gear carrier, a planetary gear set, a connector, and a planetary gearbox cover. The planetary gearbox housing and the planetary gearbox cover are fixedly connected and form a receiving cavity, within which the planetary gear carrier, the planetary gear set, and the connector are located. The planetary gear set is fixed to the planetary gear carrier and is driven to rotate via an output shaft. The planetary gear carrier is engaged with the first end of the connector, and the second end of the connector is engaged with a stud. With this configuration, when the motor is operating, the output shaft drives the planetary gear set to decelerate and rotate. With the planetary gear carrier engaged with the connector and with the connector engaged with the stud, the rotation of the planetary gear set causes the planetary gear carrier and the connector to rotate synchronously. The rotation of the connector causes the stud to rotate synchronously. When the stud rotates, it undergoes threaded movement with the threaded sleeve, thereby enabling the gearbox assembly to slide horizontally on the guide post.

[0010] According to the above scheme, the planetary gear support is provided with a positioning post, and the first end of the connector is provided with a positioning hole. The positioning post passes through the planetary gear set and is engaged with the positioning hole. With this configuration, the planetary gear set is fixed on the positioning post, and with the positioning post and positioning hole engaged, the planetary gear set rotates, driving the planetary gear support and the connector to rotate synchronously.

[0011] According to the above scheme, the second end of the connector is provided with a slot, and the stud is provided with a locking tooth, which is engaged with the slot. This configuration ensures that the stud rotates synchronously when the connector rotates.

[0012] According to the above scheme, a planetary gear positioning plate is provided between the planetary gear set and the connector. This arrangement, under the action of the planetary gear positioning plate, positions the planetary gear set, preventing displacement and disengagement, and preventing contact wear between the planetary gear set and the connector. Simultaneously, it ensures that the planetary gear set and the central gear on the output shaft remain meshed.

[0013] According to the above scheme, the planetary gear set is provided with an external gear ring 1 and an external gear ring 2, and a central gear is fixed on the output shaft. The central gear is meshed with the external gear ring 1. An internal gear ring is provided on the planetary gear box cover, and the external gear ring 2 is meshed with the internal gear ring. With this configuration, when the output shaft rotates, it drives the central gear to rotate synchronously. Under the meshing connection of the central gear with the external gear ring 1, and under the meshing connection of the external gear ring 2 with the internal gear ring, the planetary gear set is driven to rotate synchronously.

[0014] According to the above scheme, the first fixed base is equipped with a first limit switch corresponding to the gearbox assembly, and the second fixed base is equipped with a second limit switch corresponding to the gearbox assembly and a bearing corresponding to the output shaft. With this configuration, during initial operation, the motor rotates in the forward direction. When the gearbox assembly moves to touch the second limit switch, the motor rotates in the reverse direction. When the gearbox assembly moves to touch the first limit switch, the machine stops, completing one mixing cycle.

[0015] The ice cream machine described in this utility model includes the aforementioned transmission device.

[0016] The beneficial effects of this utility model are: In this invention, the drive assembly drives the output shaft to rotate during operation. Under the action of the gearbox assembly, the output shaft rotates, causing the stud to rotate. Since the stud and the sleeve are threadedly connected, the stud rotates and undergoes threaded movement with the sleeve, causing the gearbox assembly and the drive assembly to slide. This, in turn, causes the output shaft to extend and retract horizontally relative to the fixed seat, achieving horizontal extension and retraction while the output shaft rotates. Furthermore, by setting the transmission device horizontally, its overall height can be reduced, thus occupying less space. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 6 As shown, the transmission device of this utility model includes a first fixed seat 121, an output shaft 123, a guide post 124, a gearbox assembly 126, a second fixed seat 1210, and a drive assembly. The first fixed seat 121 and the second fixed seat 1210 are horizontally spaced apart. The guide post 124 is fixed between the first fixed seat 121 and the second fixed seat 1210. The gearbox assembly 126 and the drive assembly are slidably mounted on the guide post 124. The first end of the output shaft 123 is movably mounted on the second fixed seat 1210, and the second end of the output shaft 123 passes through the gearbox assembly 126 and is connected to the output end of the drive assembly. A threaded sleeve 127 is fixed on the second fixed seat 1210. The input end of the gearbox assembly 126 is connected to the output shaft 123. The output end of the gearbox assembly 126 is provided with a stud 1266, and the stud 1266 and the threaded sleeve 127 are threadedly connected. With this configuration, during operation, the drive assembly drives the output shaft 123 to rotate. Under the action of the gearbox assembly 126, the rotation of the output shaft 123 drives the stud 1266 to rotate. Since the stud 1266 and the threaded sleeve 127 are threadedly connected, the rotation of the stud 1266 causes threaded movement with the threaded sleeve 127, which makes the gearbox assembly 126 and the drive assembly slide, and drives the output shaft 123 to extend and retract horizontally relative to the fixed seat 1210, realizing the horizontal extension and retraction of the output shaft 123 while it rotates. In this way, by setting the transmission device horizontally, its overall height can be made smaller, so as to occupy less space.

[0021] Furthermore, the drive assembly includes a large pulley 122, a synchronous belt 1211, a small pulley 1212, a motor bracket 1213, and a motor 1214. The motor bracket 1213 is slidably mounted on the guide post 124, and the motor 1214 is mounted on the motor bracket 1213. The output end of the motor 1214 is drivenly connected to the small pulley 1212, and the large pulley 122 is engaged with the second end of the output shaft 123. The synchronous belt 1211 is wound around the small pulley 1212 and the large pulley 122. With this configuration, when the motor 1214 is working, it drives the small pulley 1212 to rotate at high speed, and under the action of the synchronous belt 1211, it drives the large pulley 122 and the output shaft 123 to achieve decelerated rotation.

[0022] Preferably, there are three guide pillars 124 arranged in a triangular shape between the first fixed seat 121 and the second fixed seat 1210 as a bridge support, and the transmission output is carried out by horizontal movement.

[0023] Furthermore, the large pulley 122 is provided with a flat hole, and the second end of the output shaft 123 is provided with a flat portion, which is inserted into the flat hole. This arrangement allows the large pulley 122 and the second end of the output shaft 123 to be locked together, so that when the large pulley 122 rotates, it can drive the output shaft 123 to rotate.

[0024] Furthermore, the gearbox assembly 126 includes a planetary gearbox base 1261, a planetary gear carrier 1262, a planetary gear set 1263, a connector 1265, and a planetary gearbox cover 1267; the planetary gearbox base 1261 and the planetary gearbox cover 1267 are fixedly connected and form a receiving cavity, and the planetary gear carrier 1262, the planetary gear set 1263, and the connector 1265 are located in the receiving cavity; the planetary gear set 1263 is fixed on the planetary gear carrier 1262, and the planetary gear set 1263 is driven to rotate through the output shaft 123; the planetary gear carrier 1262 is engaged with the first end of the connector 1265, and the second end of the connector 1265 is engaged with the stud 1266. With this configuration, when the motor 1214 is working, the output shaft 123 drives the planetary gear set 1263 to decelerate and rotate. With the planetary gear support 1262 and the connector 1265 locked together, and with the connector 1265 and the stud 1266 locked together, when the planetary gear set 1263 rotates, it drives the planetary gear support 1262 and the connector 1265 to rotate synchronously. When the connector 1265 rotates, it drives the stud 1266 to rotate synchronously. When the stud 1266 rotates, it undergoes threaded movement with the threaded sleeve 127, thereby realizing the horizontal sliding of the gearbox assembly 126 on the guide post 124.

[0025] The stud 1266 has an external thread on its outer circumference, and the sleeve 127 has an internal thread on its inner hole near one end of the stud 1266. The connector 1265 has its first end located in the accommodating cavity and its second end extending out of the planetary gearbox cover 1267 and engaging with the stud 1266.

[0026] Furthermore, the planetary gear support 1262 is provided with a positioning post 12621, and the first end of the connector 1265 is provided with a positioning hole 12652. The positioning post 12621 passes through the planetary gear set 1263 and is engaged with the positioning hole 12652. With this configuration, the planetary gear set 1263 is fixed on the positioning post 12621. With the positioning post 12621 and the positioning hole 12652 engaged, the planetary gear set 1263 rotates, causing the planetary gear support 1262 and the connector 1265 to rotate synchronously.

[0027] Preferably, there are three positioning posts 12621 arranged in a triangular shape on the planetary gear support 1262, and the three planetary gears are arranged in a triangular shape to form a planetary gear set 1263. The positioning posts 12621 and the planetary gear set 1263 are fixed by plugging or snapping. For example, the planetary gear set 1263 has a flat hole, and the positioning post 12621 has a flat part, which is plugged into the flat hole.

[0028] Furthermore, the second end of the connector 1265 is provided with a slot 12651, and the stud 1266 is provided with a tooth 12661, which is engaged with the slot 12651. This arrangement ensures that the stud 1266 rotates synchronously when the connector 1265 rotates.

[0029] The slot 12651 is annularly arranged on the inner hole of the connector 1265, and the tooth 12661 is annularly arranged on the end of the stud 1266 near the connector 1265.

[0030] Furthermore, a planetary gear positioning plate 1264 is provided between the planetary gear set 1263 and the connector 1265. This arrangement, under the action of the planetary gear positioning plate 1264, positions the planetary gear set 1263, preventing it from dislodging and falling out, and preventing contact wear between the planetary gear set 1263 and the connector 1265. Simultaneously, it ensures that the planetary gear set 1263 and the central gear 1231 on the output shaft 123 remain meshed.

[0031] The planetary gear positioning plate 1264 is fixed to one end of the connector 1265 near the planetary gear set 1263, and the planetary gear positioning plate 1264 is provided with a through hole to facilitate the passage of the output shaft 123 and the positioning post 12621.

[0032] Furthermore, the planetary gear set 1263 is provided with an outer gear ring 12631 and an outer gear ring 2 12632, and a central gear 1231 is fixed on the output shaft 123. The central gear 1231 is meshed with the outer gear ring 12631. The planetary gear box cover 1267 is provided with an inner gear ring 12671, and the outer gear ring 2 12632 is meshed with the inner gear ring 12671. With this configuration, when the output shaft 123 rotates, it drives the central gear 1231 to rotate synchronously. Under the meshing connection of the central gear 1231 with the outer gear ring 12631 and the meshing connection of the outer gear ring 2 12632 with the inner gear ring 12671, the planetary gear set 1263 is driven to rotate synchronously.

[0033] Furthermore, the first fixed base 121 is equipped with a first limit switch 125 corresponding to the gearbox assembly 126, and the second fixed base 1210 is equipped with a second limit switch 129 corresponding to the gearbox assembly 126 and a bearing 128 corresponding to the output shaft 123. With this configuration, during initial operation, the motor 1214 rotates in the forward direction. When the gearbox assembly 126 moves to touch the second limit switch 129, the motor 1214 rotates in the reverse direction. When the gearbox assembly 126 moves to touch the first limit switch 125, the machine stops, completing one mixing cycle.

[0034] The bearing 128 is slidably connected to the output shaft 123 so that the screw sleeve 127, the stud 1266 and the output shaft 123 are coaxially arranged, making the output shaft 123 more stable when rotating axially.
