Description

Technical Field

[0001] The present invention relates to the technical field of food blenders, and more specifically, to a multifunctional food blender. Background Art

[0002] Existing food blenders mainly include dough mixers, egg beaters, and stuffing mixers. Among them, the dough mixer is a type of pasta machine, which mainly mixes flour and water evenly for making bread, steamed buns, etc.; the egg beater is a commonly used stirring and mixing device in food processing, used to beat thick pastes such as syrup, dough, egg liquid, cheese, etc. The egg beater is divided into manual and electric types; the stuffing mixer is an essential equipment for mixing materials, with high efficiency and easy operation. It is the first choice for making air-dried sausage products, granular and paste-like mixed sausage products, and ball products. At the same time, it is also an optional equipment for producing pasta products such as dumplings and wontons.

[0003] Although products such as dough mixers, egg beaters, and stuffing mixers are widely used in the food processing field, the ingredients processed by these products are relatively single and do not have the function of multi-purpose use. This makes the investment of small merchants relatively large. To complete the processing of a food, multiple machines need to be invested, occupying a large space. In addition, in order to fully stir the ingredients to be stirred, the rotation speed of the stirring head needs to be controlled. For example, Chinese Patent No.: CN 201720524617.2, Authorization Publication Date: May 18, 2018, Invention Creation Name: A rotating head of a food blender. The rotating head is arranged on the machine head and is driven by a motor, including a speed reducer and a planetary gear mechanism. The speed reducer is arranged at the output end of the motor; the planetary gear mechanism includes a central gear linked to the output shaft of the speed reducer and three planetary gears, and a stirring shaft is arranged on one of the planetary gears. Although this application can increase the smoothness of the rotation of the stirring shaft by using the planetary gear mechanism, the rotation of the stirring shaft controlled by this planetary gear mechanism is relatively slow. Therefore, further improvement is needed. Summary of the Invention

[0017] 3. Beneficial effects

[0018] Compared with the existing known technologies, the technical solution provided by the present invention has the following significant effects:

[0019] (1) A multifunctional food mixer of the present invention has a planetary drive mechanism between the motor and the mixing head. When working, the main shaft in the planetary drive mechanism drives the planetary gear to rotate. Under the action of the meshing of the gear teeth, the planetary gear moves along the gear ring. In addition, due to the presence of the bearing, the mixing shaft rotates while rotating, so as to achieve the mixing of food. Compared with the traditional planetary gear mechanism, the rotation speed of the mixing shaft is relatively fast during the whole process, so that the food can be mixed more fully.

[0020] (2) The multifunctional food mixer of the present invention has a main shaft whose rotation is controlled by the gear and the multi-V belt, thereby controlling the rotation of the main shaft, thereby controlling the rotation of the stirring head, that is, stirring the food ingredients; in addition, the stirring head is detachably mounted on the stirring shaft, and the stirring head includes a dough hook, a stirring paddle and an egg beating ball, so that different food ingredients can be stirred by a set of equipment, and the whole device is small in size and does not need to occupy too much space;

[0021] (3) In order to prevent the poly-V belt from becoming loose due to long-term operation, a multifunctional food mixer of the present invention is provided with a tensioning device on one side of the poly-V belt. Due to the presence of a torsion spring on the tensioning device, the tensioning wheel housing is always in contact with the poly-V belt, thereby effectively ensuring that the poly-V belt is in a tightened state, which is beneficial to controlling the rotation of the main shaft;

[0022] (4) A multifunctional food mixer of the present invention controls the bracket to move up and down along the height direction of the machine body through a lifting mechanism, so that it is convenient for the user to take the bucket from the bracket. In addition, the lifting mechanism adopts a turbine and a worm for transmission, so that the bracket is more stable during the movement. At the same time, the structure cooperates with the crank, the connecting rod, and the limit groove to control the movement range of the bracket, effectively avoiding the problem of mutual collision between the components.

[0023] (5) A multifunctional food mixer of the present invention has a pad at each end of a bracket, and a positioning pin and a locking handle are installed on the pad. When the material barrel is placed on the bracket, it is positioned by the positioning pin and pressed by the locking handle, thereby ensuring that the material barrel is stably installed on the bracket; in addition, due to the presence of the pad, wear on the upper surface of the bracket can be avoided.

[0040] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments.

[0041] Embodiment 1

[0042] A multifunctional food mixer in this embodiment, combined with Figure 1 and Figure 2 , includes a body 10 installed on a foot plate 47. A bracket 2 is vertically installed on the body 10. The bracket 2 is used to place a hopper 1. A box body 8 is also provided on the body 10. A motor mounting plate 11 is provided inside the box body 8. A motor 12 is installed on the motor mounting plate 11. The motor 12 is used to drive a stirring head to rotate, and the ingredients in the hopper 1 are stirred by the stirring head.

[0043] In the prior art, in order to facilitate the control of the rotation of the stirring head and make the stirring head have a certain rotational speed, so as to facilitate the stirring of ingredients. However, in the prior art, a planetary gear mechanism is used for transmission to control the rotation of the stirring head. However, when the rotation of the stirring head is controlled in this way, the rotation speed of the stirring head is relatively slow, resulting in a relatively low working efficiency of the stirring head.

[0044] To solve this problem, a planetary drive mechanism is provided between the motor 12 and the stirring head in this embodiment. The planetary drive mechanism replaces the planetary gear mechanism in the prior art, so that the rotation speed of the stirring head is relatively fast during use.

[0045] Specifically, combined with Figure 3, the planetary gear mechanism of this embodiment includes a main shaft 18, a key 49, a planet carrier 24, and a stirring shaft 25. Among them, the planet carrier 24 is fixedly installed on the box body 8, and the planet carrier 24 faces the bracket 2. The main shaft 18 is fixedly installed on the planet carrier 24 through the key 49, as Figure 2 shown. The main shaft 18 is arranged along the vertical direction, and the main shaft 18 is installed in the middle of the planet carrier 24. In this embodiment, the main shaft 18 is driven by a motor 12. In addition, the stirring shaft 25 of this embodiment is movably installed on the planet carrier 24 through a bearing, and the stirring shaft 25 is eccentrically arranged. A planetary gear 23 is fixedly installed on the stirring shaft 25, and the planetary gear 23 meshes with a toothed ring 22 on the planet carrier 24. The stirring head is installed on the stirring shaft 25.

[0046] During operation, the motor 12 is started to control the rotation of the main shaft 18. Due to the presence of the key 49, the planet carrier 24 rotates together with the main shaft 18. Under the action of gear tooth meshing, the stirring shaft 25 rotates around the axis of the main shaft 18. At the same time, since a bearing is provided between the stirring shaft 25 and the planet carrier 24, the stirring shaft 25 rotates on its own while rotating, that is, the stirring head rotates while controlling the self-rotation of the stirring head, so as to fully realize the stirring of food. And compared with the traditional planetary gear mechanism during the whole process, the rotation speed of the stirring shaft 25 is relatively fast, and the ingredients can be stirred more fully.

[0047] In addition, as Figures 4 - 6 shown, the stirring head of this embodiment is detachably installed on the stirring shaft 25, and the stirring head includes a dough hook 43, a stirring paddle 44, and a whisk 45. Different ingredients can be stirred by one set of equipment. The whole device has a small overall volume, does not need to occupy too much space, and is convenient for the operator to use.

[0048] Embodiment 2

[0049] A multifunctional food blender of this embodiment is basically the same as Embodiment 1. Further, in combination with Figure 2 , a gearbox 21 is provided inside the box body 8 of this embodiment. A large gear 19 is fixedly installed on the main shaft 18. The large gear 19 is located inside the gearbox 21, and the upper end of the gearbox 21 is sealed by a box cover 20. Bearings are provided at the contact points of the main shaft 18 with the box cover 20 and the gearbox 21 to facilitate the rotation of the main shaft 18. The main shaft 18 extends out of the gearbox 21 and is connected to the planet carrier 24. The large gear 19 meshes with a tooth shaft 17. One end of the tooth shaft 17 extending out of the box cover 20 is fixedly installed with a large pulley 16. A small pulley 13 is installed on the output shaft of the motor 12. The large pulley 16 and the small pulley 13 are connected by a multi-wedge belt 14.

[0050] When the motor 12 is working, its output shaft rotates, and under the action of the poly-V belt 14, the gear shaft 17 rotates accordingly, and under the action of the gear meshing, the main shaft 18 is driven to rotate. In this embodiment, the gears and the poly-V belt 14 cooperate with each other to jointly control the rotation of the main shaft 18, thereby controlling the rotation of the stirring head, that is, realizing the stirring of the food.

[0051] Preferably, in order to avoid the problem of loosening caused by long-term operation of the poly-V belt 14, Figure 7 In this embodiment, a tensioning device 15 is provided on one side of the multi-V belt 14, and the tensioning device 15 includes a tensioning wheel shell 38, a lever 39, a torsion spring shaft 41 and a torsion spring 42, wherein the lever 39 is hingedly mounted on the torsion spring shaft 41, and the lever 39 is positioned by a cotter pin 40; the torsion spring 42 is sleeved on the torsion spring shaft 41, and the upper and lower ends of the torsion spring shaft 41 are respectively limited by a block, wherein one block is arranged on the lever 39, and the other block is arranged on the motor mounting plate 11, and the torsion spring shaft 41 is mounted on the motor mounting plate 11; the tensioning wheel shell 38 is movably mounted on the lever 39 through a bearing, and the tensioning wheel shell 38 is always in contact with the multi-V belt 14, thereby effectively ensuring that the multi-V belt 14 is in a tensioned state, which is beneficial to controlling the rotation of the main shaft 18.

[0052] Example 3

[0053] The multifunctional food mixer of this embodiment is basically the same as that of the second embodiment, and further, Figure 1 , Figure 8 , Figure 9 In order to facilitate the user to take and place the barrel 1 from the bracket 2, a lifting mechanism 9 is provided on the fuselage 10 in this embodiment, and the lifting mechanism 9 is used to control the bracket 2 to move up and down along the height direction of the fuselage 10.

[0054] Specifically, the lifting mechanism 9 of this embodiment includes a handwheel 27, a turbine mounting plate 28, a turbine 29, a crank 30 and a worm 32, wherein the turbine mounting plate 28 is mounted on the column plate 46 of the fuselage 10, the worm 32 is meshed with the turbine 29 on the turbine mounting plate 28, the crank 30 is mounted on the turbine 29, and a connecting rod 31 is hinged on the crank 30, the connecting rod 31 is hinged on the bracket 2, and a limiting groove is opened in the height direction of the fuselage 10, and the limiting groove is used to limit the movement of the connecting rod 31.

[0055] Furthermore, combined Figure 10 In this embodiment, the bracket 2 is movably mounted on a guide rail 36 , and the guide rail 36 is arranged along the height direction of the fuselage 10 .

[0056] Preferably, a through hole is provided on the column plate 46, such as Figure 9As shown, the guide rail 36 is installed on the through hole, and the limit groove is located on the guide rail 36. The width of the through hole is greater than the width of the guide rail 36, and the distances from both sides of the guide rail 36 to both sides of the through hole are equal, so that the bracket 2 can be movably installed on the guide rail 36, which is beneficial to the movement of the bracket 2. In addition, in this embodiment, a protective cover 37 is installed on the side of the column plate 46 facing the bracket 2 to protect the guide rail 36 through the protective cover 37. At the same time, two inner dust covers 26 are installed on the side away from the bracket 2, and the inner dust covers 26 are used to seal the gap between the guide rail 36 and the through hole to prevent dust from entering the interior of the mixer.

[0057] When the user uses it, rotate the handwheel 27. Under the action of the meshing of the gear teeth, the driving crank 30 rotates, thereby driving the connecting rod 31 to move. Under the action of the limit groove, the bracket 2 can be controlled to move up and down reciprocally along the guide rail 36, and the height of the bucket 1 can be adjusted.

[0058] The lifting mechanism 9 of this embodiment uses a turbine 29 and a worm 32 for transmission, so that the bracket 2 is more stable during the movement. At the same time, this structure cooperates with the crank 30, the connecting rod 31, and the limit groove to control the moving range of the bracket 2, effectively avoiding the problem of mutual collision between components.

[0059] In addition, as Figure 10 shown, in this embodiment, a cushion plate 33 is provided at each end of the bracket 2. A positioning pin 34 and a locking handle 35 are installed on the cushion plate 33. After the bucket 1 is placed on the bracket 2, it is positioned by the positioning pin 34, and the locking handle 35 presses it, so as to ensure that the bucket 1 is stably installed on the bracket 2; in addition, due to the presence of the cushion plate 33, the upper surface of the bracket 2 can be prevented from being worn.

[0060] Embodiment 4

[0061] A multifunctional food mixer of this embodiment is basically the same as that of Embodiment 3. Further, as Figure 11 shown, in this embodiment, a head shield 6 is installed at the upper end of the box body 8, and a support step 48 is provided in the contact area between the head shield 6 and the box body 8 to increase its ability to resist external forces through the support step 48.

[0062] As Figure 12 and Figure 13 shown, in order to increase the structural strength of the fuselage 10, the column plate 46 and the foot plate 47 of the fuselage 10 are connected by welding, and the lower edge of the column plate 46 is bent outward, as Figure 12 shown by the bending line A in Figure 14 shown. In addition, as

[0063] As Figure 1As shown in the figure, in this embodiment, a control panel 7 is provided on one side of the box body 8. The control panel 7 is a human-machine interaction interface, which is used to control the start, stop, time setting, speed setting, speed display, time display, etc. of the blender, so as to facilitate the use by the user.

[0064] In addition, a shield mounting seat 5 is provided at one end of the box body 8 facing the bracket 2. An active shield 3 and a fixed shield 4 are mounted on the shield mounting seat 5. The material bucket 1 is protected by the active shield 3 and the fixed shield 4, so as to prevent the operator from being injured during the operation of the blender.
