Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice cream processing technology, and in particular to an extrusion device for ice cream processing. Background Technology
[0002] In the current ice cream processing industry, the technological development of extrusion equipment has a crucial impact on product diversity and production efficiency. Most existing ice cream extrusion equipment has significant limitations, lacking flexibility in flavor production modes. Many traditional extrusion units can only focus on producing a single flavor of ice cream. These devices are often equipped with only a single storage hopper and a simple extrusion structure, designed around a single material from raw material storage to the extrusion process, unable to handle multiple materials simultaneously. Even some extrusion units capable of producing mixed flavors have functional deficiencies. Although they have multiple storage hoppers, they struggle to freely and quickly switch between single-flavor and mixed-flavor production modes. The drive components corresponding to multiple storage hoppers lack independent control capabilities, making it impossible to easily switch to outputting only a specific material when needed. Utility Model Content
[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an extrusion device for ice cream processing, which solves the problem that the ice cream extrusion device in the prior art cannot freely switch between single flavor and mixed flavor.
[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:
[0005] An extrusion device for ice cream processing includes a storage tank and a partition disposed in the middle of the storage tank, the partition dividing the storage tank into a first storage bin and a second storage bin. Both the first and second storage bins are equipped with auger blades. The auger blades include a first auger blade disposed in the first storage bin and a second auger blade disposed in the second storage bin. A mixing bin is disposed at the bottom of the storage tank. The first storage bin has a first inlet connected to the outside and a first outlet connected to the mixing bin. The second storage bin has a second inlet connected to the outside and a second outlet connected to the mixing bin. A drive device for rotating the first and / or second auger blades is disposed at the top of the storage tank.
[0006] To achieve the above technical solution, ice cream ingredients of different flavors or ingredients are added to the first and second storage bins respectively through the first and second feed inlets. The drive unit can independently drive the first or second auger blades to rotate, achieving independent output of ingredients from a single storage bin. When making mixed-flavor ice cream, the drive unit can simultaneously drive the first and second auger blades to rotate. By independently controlling the rotation speed of the two auger blades, the drive unit can precisely adjust the extrusion volume of the material. Compared to traditional mixing methods, this precise proportion control avoids flavor deviations caused by imbalances in material ratios, ensuring that each batch of mixed-flavor ice cream maintains a stable and high-quality taste, thus improving product quality and brand image. When only a single material is needed for production, the drive unit only drives the corresponding auger blade, reducing unnecessary equipment operation and energy consumption.
[0007] In one embodiment of the present invention, the driving device includes a fixed plate, a drive motor disposed on the fixed plate, a rotating shaft disposed on the output shaft of the drive motor, a drive gear fixed on the rotating shaft, and two drive components symmetrically disposed on both sides of the rotating shaft and respectively driving the two auger blades to rotate.
[0008] To achieve the above technical solution, the drive motor transmits power to two symmetrically arranged drive components simultaneously through the drive gear on the rotating shaft. Through the gear meshing relationship, the single motor achieves linkage control of the first and second auger blades. When producing single-flavor ice cream, the drive device directs power only to the drive component connected to the first auger blade or the drive component connected to the second auger blade. When making mixed-flavor ice cream, the drive device outputs power to both drive components simultaneously, thereby driving the first and second auger blades to rotate at the same time.
[0009] In one embodiment of the present invention, the drive assembly includes a spline shaft disposed at the top of the auger blade, a bushing that slides up and down on the spline shaft, and a driven gear disposed outside the bushing and meshing with the drive gear.
[0010] To achieve the above technical solution, the spline shaft is located at the top of the auger blade and is a key component connecting the auger blade and other parts of the drive assembly. The bushing allows it to move up and down to a limited extent along the spline shaft, which facilitates the adjustment of the meshing state between the gears. The driven gear is sleeved outside the bushing and meshes with the driving gear. The driven gear receives power from the drive motor through meshing with the driving gear and transmits this power to the auger blade through the bushing and spline shaft, causing the auger blade to rotate.
[0011] In one embodiment of the present invention, the bushing is provided with a switching component that drives the driven gear and the driving gear to switch between meshing and non-meshing states.
[0012] To achieve the above technical solution, a special switching component is installed on the bushing. This component controls the position of the driven gear relative to the driving gear, thereby switching between the meshing and non-meshing states of the driven and driving gears. When it is necessary to drive the first or second auger blade individually, the switching component can be used to move the corresponding driven gear out of its meshing position with the driving gear. If it is necessary to drive both auger blades simultaneously, the switching component makes both driven gears mesh with the driving gear, ensuring that power can be transmitted to both auger blades simultaneously.
[0013] In one embodiment of the present invention, the switching assembly includes a bearing plate disposed on the bushing and a switching cylinder disposed on the fixed plate with its telescopic end fixedly connected to the bearing plate; the switching cylinder is capable of driving the bearing plate and causing the driven gear on the bushing to move up and down on the spline shaft.
[0014] To achieve the above technical solution, the switching cylinder can drive the bearing plate to move up and down, thereby causing the bushing and the driven gear mounted on it to move up and down along the spline shaft. In this way, the meshing or non-meshing state between the driven gear and the driving gear can be precisely controlled.
[0015] As described above, the extrusion device for ice cream processing of this utility model has the following beneficial effects: the driving device can drive the first auger blade or the second auger blade to rotate independently, realizing the independent output of raw materials from a single storage bin; while when making mixed flavor ice cream, the driving device can drive the first auger blade and the second auger blade to rotate simultaneously. By independently controlling the rotation speed of the two auger blades, the driving device can accurately adjust the extrusion amount of the material. This design greatly improves the flexibility of production. Attached Figure Description

Detailed Implementation
[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.
[0021] Please see Figures 1 to 2 This utility model provides an extrusion device for ice cream processing, including a storage tank 1 and a partition 2 disposed in the middle of the storage tank 1. The partition 2 divides the storage tank 1 into a first storage bin 3 and a second storage bin 4. Both the first storage bin 3 and the second storage bin are provided with auger blades. The auger blades include a first auger blade 5 disposed in the first storage bin 3 and a second auger blade 6 disposed in the second storage bin 4. A mixing bin 7 is disposed at the bottom of the storage tank 1. The first storage bin 3 is provided with a first inlet 8 communicating with the outside and a first outlet 9 communicating with the mixing bin 7. The second storage bin 4 is provided with a second inlet 10 communicating with the outside and a second outlet 11 communicating with the mixing bin 7. A driving device for driving the first auger blade 5 and / or the second auger blade 6 to rotate is disposed at the top of the storage tank 1.
[0022] Different flavors or ingredients of ice cream are added to the first storage bin 3 and the second storage bin 4 through the first feed inlet 8 and the second feed inlet 10, respectively. The drive unit can drive the first auger blade 5 or the second auger blade 6 to rotate independently, achieving independent output of raw materials from a single storage bin. When making mixed-flavor ice cream, the drive unit can drive the first auger blade 5 and the second auger blade 6 to rotate simultaneously. By independently controlling the rotation speed of the two auger blades, the drive unit can precisely adjust the extrusion volume of the material. Compared with traditional mixing methods, this precise proportion control avoids flavor deviations caused by imbalances in material ratios, ensuring that each batch of mixed-flavor ice cream maintains a stable and high-quality taste, thus improving product quality and brand image. When only a single material is needed for production, the drive unit only drives the corresponding auger blade, reducing unnecessary equipment operation and energy consumption.
[0023] The drive device includes a fixed plate 12, a drive motor 13 mounted on the fixed plate 12, a rotating shaft 14 mounted on the output shaft of the drive motor 13, a drive gear 15 fixed on the rotating shaft 14, and two drive components symmetrically arranged on both sides of the rotating shaft 14 and respectively driving the two auger blades to rotate.
[0024] The drive motor 13 transmits power to two symmetrically arranged drive components simultaneously through the drive gear 15 on the rotating shaft 14. Through the gear meshing relationship, the single motor achieves linkage control of the first auger blade 5 and the second auger blade 6. When producing single-flavor ice cream, the drive device directs power only to the drive component connected to the first auger blade 5 or the drive component connected to the second auger blade 6. When making mixed-flavor ice cream, the drive device outputs power to both drive components simultaneously, thereby driving the first auger blade 5 and the second auger blade 6 to rotate at the same time.
[0025] The drive assembly includes a splined shaft 16 disposed at the top of the auger blade, a bushing 17 that slides up and down on the splined shaft 16, and a driven gear 18 disposed outside the bushing 17 and meshing with the drive gear 15.
[0026] The splined shaft 16 is located at the top of the auger blade and is a key component connecting the auger blade and other parts of the drive assembly. The bushing 17 allows it to move up and down to a limited extent along the splined shaft 16, which facilitates the adjustment of the meshing state between the gears. The driven gear 18 is sleeved outside the bushing 17 and meshes with the drive gear 15. The driven gear 18 receives power from the drive motor 13 through meshing with the drive gear 15 and transmits this power to the auger blade through the bushing 17 and the splined shaft 16, causing the auger blade to rotate.
[0027] The bushing 17 is provided with a switching component that drives the driven gear 18 and the driving gear 15 to switch between meshing and non-meshing states.
[0028] A special switching component is provided on the bushing 17. This component can control the position of the driven gear 18 relative to the driving gear 15, thereby switching the meshing or non-meshing state between the driven gear 18 and the driving gear 15. When it is necessary to drive the first auger blade 5 or the second auger blade 6 individually, the corresponding driven gear 18 can be moved out of the meshing position with the driving gear 15 by the switching component. If it is necessary to drive both auger blades simultaneously, the switching component can be used to make both driven gears 18 mesh with the driving gear 15, ensuring that power can be transmitted to both auger blades simultaneously.
[0029] The switching assembly includes a bearing plate 19 disposed on the bushing 17 and a switching cylinder 20 disposed on the fixed plate 12 and whose telescopic end is fixedly connected to the bearing plate 19; the switching cylinder 20 can drive the bearing plate 19 and drive the driven gear 18 on the bushing 17 to move up and down on the spline shaft 16.
[0030] The switching cylinder 20 can drive the bearing plate 19 to move up and down, thereby causing the bushing 17 and the driven gear 18 mounted on it to move up and down along the spline shaft 16. In this way, the meshing or non-meshing state between the driven gear 18 and the driving gear 15 can be precisely controlled.
[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
