Description

Technical Field

[0001] This utility model relates to the field of stirring mechanism technology, and more specifically to a crank-connecting rod stirring mechanism. Background Technology

[0002] For some beverage ingredients, such as liquid beverage ingredients, separation is likely to occur after prolonged standing. For ingredients that are a mixture of liquid and particulate matter, the particulate matter is likely to sink after prolonged standing. Before use, the ingredients need to be stirred to avoid separation and to prevent the particulate matter from sinking and affecting the use. For some ingredients that are a mixture of multiple powders or granules, they need to be stirred to ensure that the different powders or granules are evenly mixed to avoid uneven mixing affecting the taste of the beverage made later.

[0003] There are two existing methods for mixing beverage ingredients:

[0004] The first method uses a built-in stirring fan (or stirring rod, etc.) to achieve a stirring effect. This method has the problem of difficulty in cleaning the stirring fan (stirring rod). If it is not cleaned properly, it will affect the taste of the drink when used again.

[0005] The second method is to achieve the stirring function by blowing air through the built-in air outlet. This method requires multiple filtrations of the gas to ensure that the gas is dry, clean and hygienic, which has the risks of high cost and secondary contamination of raw materials.

[0006] Therefore, the applicant proposes a crank-connecting rod stirring mechanism to stir and mix raw materials in their original packaging, eliminating the risk of secondary contamination of raw materials and avoiding the problem of difficult cleaning of the stirring mechanism. Utility Model Content

[0007] In view of this, the present invention provides a crank-connecting rod stirring mechanism.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a crank-connecting rod stirring mechanism, comprising a crank-connecting rod stirring assembly and a motor; the crank-connecting rod stirring assembly includes: a fixed plate, multiple parallel rotating rods mounted on the fixed plate, multiple rocking rods, a connecting plate connected to the multiple rocking rods, a connecting rod, and a crank mounted on the fixed plate; one rocking rod is installed corresponding to each of the rotating rods; the first end of the connecting rod is rotatably connected to the crank; the second end of the connecting rod is connected to one of the rocking rods; the upper part of the raw material bag is connected to the rotating rod, and the lower part of the raw material bag is connected to the rocking rod; the motor drives the crank to rotate, and the crank drives the multiple rocking rods to swing back and forth through the connecting rod and the connecting plate, and the rocking rods drive the raw material bag to swing;

[0009] This technology uses a motor to drive a crank to rotate, which in turn drives multiple rocker arms to oscillate back and forth via connecting rods and a connecting plate. This oscillation causes the raw material bag to swing back and forth, mixing and stirring the raw materials inside the bag to prevent separation. The crank-connecting rod stirring mechanism mixes the entire bag of raw materials without the need for additional stirring components to be inserted into the bag, avoiding the problem of difficult-to-clean stirring components and the resulting impact on raw material quality and taste. The crank-connecting rod stirring mechanism can simultaneously stir multiple bags of raw materials, improving stirring efficiency.

[0010] In a preferred embodiment of this utility model, the opening end of the rotating rod is installed on the fixed plate; the rocking rod includes a connecting rod segment and a supporting rod segment connected together, the opening end of the connecting rod segment being connected to the rotating rod, and the supporting rod segment supporting the lower part of the raw material bag; this technology defines a specific implementable method of the rocking rod, and this design of the rocking rod can ensure that the rocking rod drives the raw material bag to swing during the swinging process, ensuring the mixing effect of the raw material.

[0011] In a preferred embodiment of this utility model, the connecting rod segment and the support rod segment are connected in an "L" shape, and the support rod segment is parallel to the rotating rod. In this technology, the rocking rod is set in an "L" shape, with the rocking rod serving as the fulcrum of rotation, while the lower part of the raw material bag is supported by the support rod. The rocking arm is relatively long during swinging to ensure the stirring effect.

[0012] As a preferred embodiment of this utility model, the opening of the connecting rod segment is provided with a connecting ear, which is sleeved on the rotating rod; this technology defines the specific connection method of the rocker arm and the rotating rod, and the installation method is simple.

[0013] As a preferred embodiment of this utility model, the rocker arm is provided with a short shaft; the connecting plate is provided with a shaft hole; when the connecting plate is installed on the rocker arm, the short shaft passes through the shaft hole; this technology defines the specific connection method between the rocker arm and the connecting plate, and the installation method is simple and convenient by using the short shaft and the shaft hole for installation.

[0014] As a preferred embodiment of this utility model, one of the rocker arms is provided with a pin; the second end of the connecting rod is provided with a hole; when the connecting rod is connected to the rocker arm, the pin is inserted into the hole; this technology defines the specific connection method of the rocker arm and the connecting rod, and the installation is simple and convenient by using the pin and the hole.

[0015] In a preferred embodiment of this utility model, all of the multiple rotating rods are perpendicular to the fixed plate; a gap is formed between two adjacent rotating rods to ensure that the raw material bag has sufficient installation space.

[0016] As a preferred embodiment of this utility model, the crank-connecting rod mixing assembly is provided in two sets: an upper crank-connecting rod mixing assembly and a lower crank-connecting rod mixing assembly. The connecting rods of the upper crank-connecting rod mixing assembly and the lower crank-connecting rod mixing assembly are connected by a connecting rod. This technology limits the crank-connecting rod mixing assembly to two sets, namely an upper crank-connecting rod mixing assembly and a lower crank-connecting rod mixing assembly, which can increase the amount of raw materials that can be mixed at one time, such as mixing 12 bags of raw materials at one time, thereby improving efficiency.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] A crank-connecting rod stirring mechanism, please refer to Figure 1-3 As shown, it includes a crank-connecting rod stirring assembly 100 and a motor 200. The crank-connecting rod stirring mechanism is used to drive the raw material bag 300 containing raw materials to swing, thereby realizing the stirring of the raw materials in the raw material bag 300.

[0030] The crank-connecting rod stirring assembly 100 includes: a fixed plate 110, a rotating rod 120, a rocking rod 130, a connecting plate 140, a connecting rod 150, and a crank 160;

[0031] The fixing plate 110 mainly serves a supporting function, and the fixing plate 110 can be designed as follows: Figure 1-2 The elongated plate shape shown can also be designed in other shapes. The fixing plate 110 has multiple through holes. The opening of the rotating rod 120 is installed in one of these through holes. The opening of the rotating rod 120 can be fixedly installed in the through hole, such as by screw locking or welding. Alternatively, the opening of the rotating rod 120 can be rotatably installed in the through hole, such as by a pin. Figure 1 As shown, the rotating rod 120 is also vertically mounted on the fixed plate 110; multiple rotating rods 120 are parallel to each other.

[0032] The number of rotating rods 120 is set according to actual needs, such as Figure 2 As shown, in this embodiment, there are six rotating rods 120, and one rocker arm 130 is configured for each rotating rod 120, so a maximum of six bags of raw materials can be stirred at the same time. However, according to actual needs, even if the crank connecting rod stirring assembly 100 is equipped with six rotating rods 120, only one or two bags of raw materials can be placed, and only one or two bags of raw materials can be stirred.

[0033] Optionally, the number of rotating rods 120 can be increased or decreased according to actual needs. For example, if the number of rotating rods 120 can be reduced to four, then four rocker rods 130 will be configured; or if the number of rotating rods 120 can be increased to eight, then eight rocker rods 130 will be configured.

[0034] The connecting plate 140 connects multiple rocker arms 130, enabling the multiple rocker arms 130 to swing synchronously. The crank 160 is mounted on the fixed plate 110 and is rotatably mounted on the fixed plate 110. The first end of the connecting rod 150 is rotatably connected to the crank 160. The connection point between the connecting rod 150 and the crank 160 is defined as connection point A. When the crank 160 rotates, it rotates around the center point O. Connection point A and center point O do not overlap, so that when the crank 160 rotates, it can pull the connecting rod 150 to move. The second end of the connecting rod 150 is connected to one of the rocker arms 130. Since the multiple rocker arms 130 are connected by the connecting plate 140, when the connecting rod 150 pulls one of the rocker arms 130 to swing, the multiple rocker arms 130 swing synchronously.

[0035] Motor 200 drives crank 160 to rotate. Motor 200 can directly drive crank 160 to rotate, such as... Figure 1 As shown, the output shaft of the motor 200 is equipped with a transition shaft 210. The transition shaft 210 is provided with a non-circular insertion part, which is preferably hexagonal or octagonal. The crank 160 is provided with a shaft hole at the center point O, which is hexagonal or octagonal. The insertion part is inserted into the shaft hole. When the motor 200 rotates, it drives the crank 160 to rotate.

[0036] Optionally, the motor 200 can indirectly drive the crank 160 to rotate, such as by a belt drive assembly between the motor 200 and the crank 160, or by a gearbox, etc.

[0037] like Figure 1 and Figure 2 As shown, the first end of the connecting rod 150 is connected to a pin or a fixing screw. The pin or fixing screw is installed at the connection point A of the crank 160, and the first end of the connecting rod 150 can rotate around the pin or fixing screw.

[0038] In this embodiment, a fixing screw is used.

[0039] The raw material bag 300 can be a plastic bag, paper bag, kraft bag, etc., as long as it can hold the raw materials; the upper part of the raw material bag 300 is connected to the rotating rod 120, and the lower part of the raw material bag 300 is connected to the rocking rod 130. When the rocking rod 130 swings, it drives the raw material bag 300 to swing, ultimately achieving the stirring of the raw materials in the raw material bag 300.

[0040] In one embodiment, the beginning of the rotating rod 120 is installed on the fixed plate 110, and multiple rotating rods 120 are perpendicular to the fixed plate 110. A gap is formed between two adjacent rotating rods 120, so that there is enough installation space when multiple raw material bags 300 are arranged and installed.

[0041] The rocker arm 130 includes a connecting rod segment 131 and a support rod segment 132 connected to each other. The beginning of the connecting rod segment 131 is connected to the rotating rod 120. The support rod segment 132 supports the lower part of the raw material bag 300. When the rocker arm 130 swings, it swings around the connection between the connecting rod segment 131 and the rotating rod 120. The support rod segment 132 can support the raw material bag 300 well, ensuring that the rocker arm 130 can drive the raw material bag 300 to swing.

[0042] Furthermore, the connecting rod segment 131 and the support rod segment 132 are connected in an "L" shape, with the support rod segment 132 parallel to the rotating rod 120;

[0043] The connecting rod segment 131 and the support rod segment 132 can be integrally molded to reduce assembly steps.

[0044] Furthermore, a connecting ear 1311 is provided at the beginning of the connecting rod segment 131. The connecting ear 1311 is sleeved on the rotating rod 120. The installation method is simple, and the rocker arm 130 can swing around the rotating rod 120.

[0045] like Figure 2 As shown, a neck 121 is provided near the opening of the rotating rod 120. The diameter of the neck 121 is smaller than the diameter of the rotating rod 120. A connecting ear 1311 is fitted onto the neck 121. The inner diameter of the through hole of the connecting ear 1311 can be equal to or slightly larger than the diameter of the neck 121. After the connecting ear 1311 is installed on the neck 121, it can prevent the connecting ear 1311 from moving along the length direction of the rotating rod 120.

[0046] In one embodiment, the rocker arm 130 is provided with a short shaft 133, and the connecting plate 140 is provided with a shaft hole 141. When the connecting plate 140 is installed on the rocker arm 130, the short shaft 133 passes through the shaft hole 141, making the installation simple and quick.

[0047] like Figure 3As shown, the short shaft 133 is located at the lower part of the connecting rod segment 131, approximately at the junction of the connecting rod segment 131 and the support rod segment 132. In order to prevent the short shaft 133 from exiting the shaft hole 141, a spherical protrusion can be provided at the end of the short shaft 133 away from the connecting rod segment 131. The protrusion is slightly larger than the inner diameter of the shaft hole 141, which can play a limiting role.

[0048] The short shafts 133 of the multiple rocker arms 130 are positioned in the same location.

[0049] In one embodiment, one of the rocker arms 130 is provided with a pin 134, and the second end of the connecting rod 150 is provided with a socket 151; when the connecting rod 150 is connected to the rocker arm 130, the pin 134 is inserted into the socket 151; as Figure 3 As shown, the insertion shaft 134 is located on the upper part of the connecting rod section 131, close to the connecting ear 1311 and below the connecting ear 1311; similarly, in order to prevent the insertion shaft 134 from leaving the insertion hole 151, a spherical protrusion can be provided at the end of the insertion shaft 134 away from the connecting rod section 131. The protrusion is slightly larger than the inner diameter of the insertion hole 151, which can play a limiting role.

[0050] Optionally, each rocker arm 130 may be provided with a pin shaft 134, and when connected, the second end of the connecting rod 150 is connected to the nearest rocker arm 130.

[0051] In one embodiment, the number of crank-connecting rod stirring assemblies 100 can be varied, and may include two sets of crank-connecting rod stirring assemblies 100, such as... Figure 4 As shown, it includes: an upper crank-connecting rod stirring assembly 100a and a lower crank-connecting rod stirring assembly 100b; the upper crank-connecting rod stirring assembly 100a and the lower crank-connecting rod stirring assembly 100b have the same structure, but the number of rotating rods 120 in the upper crank-connecting rod stirring assembly 100a and the lower crank-connecting rod stirring assembly 100b can be the same or different;

[0052] Continue as Figure 4 As shown, the upper crank-connecting rod mixing assembly 100a is equipped with six rotating rods 120 and six rocker rods 130; the lower crank-connecting rod mixing assembly 100b is equipped with six rotating rods 120 and six rocker rods 130; thus, the upper crank-connecting rod mixing assembly 100a and the lower crank-connecting rod mixing assembly 100b can simultaneously mix 12 bags of raw materials.

[0053] Optionally, the upper crank-connecting rod stirring assembly 100a may be provided with six rotating rods 120 and six rocker rods 130; the lower crank-connecting rod stirring assembly 100b may be provided with four rotating rods 120 and four rocker rods 130.

[0054] During connection, continue as follows Figure 4 As shown, the connecting rod 150 of the upper crank-connecting rod stirring assembly 100a and the connecting rod 150 of the lower crank-connecting rod stirring assembly 100b are connected by a connecting rod 170. Therefore, the upper crank-connecting rod stirring assembly 100a and the lower crank-connecting rod stirring assembly 100b can be driven by a single motor 200.

[0055] One end of the connecting rod 170 is connected to the first end of the connecting rod 150 of the upper crank-connecting rod agitator 100a, and the other end of the connecting rod 170 is connected to the first end of the connecting rod 150 of the lower crank-connecting rod agitator 100b. Specifically, the connecting rod 170 is connected to the fixing screw.

[0056] Furthermore, it may also include three sets of crank-connecting rod stirring groups 100, which can be an upper crank-connecting rod stirring group, a middle crank-connecting rod stirring group, and a lower crank-connecting rod stirring group. Adjacent crank-connecting rod stirring groups 100 are connected by connecting rods 170 to realize synchronous oscillation of the three-layer crank-connecting rod stirring groups 100.

[0057] The motor 200 can be connected to the crank 160 of the crank-connecting rod stirring assembly 100 in any layer.

[0058] like Figure 1 and Figure 2 As shown, the upper part of the raw material bag 300 can be provided with an upper hole, and the lower part of the raw material bag 300 can be provided with a lower hole. When the raw material bag 300 is installed, the rotating rod 120 is inserted into the upper hole, and the support rod section 132 is inserted into the lower hole to achieve stable support for the raw material bag 300.

[0059] The working principle of this utility model is as follows:

[0060] S1. When the motor at 200 is running, it drives the crank at 160. Figure 5 The arrow indicates the direction of reciprocating rotation in both forward and reverse directions.

[0061] S2. As the crank 160 rotates, it drives the connecting rod 150 to swing. The connecting rod 150 and the connecting plate 140 work together to drive multiple rocker arms 130 to swing around the rotation axis 120, ultimately achieving the rotation of the raw material bag 300 around the rotation axis 120. Figure 5 The arrow indicates the direction of the reciprocating swing;

[0062] When the upper crank-connecting rod stirring assembly 100a is connected to the connecting rod 150 and the lower crank-connecting rod stirring assembly 100b, the upper crank-connecting rod stirring assembly 100a swings according to the previous steps S1 and S2; the lower crank-connecting rod stirring assembly 100b is connected by the connecting rod 170.

[0063] S3. Connecting rod 170 drives crank 160 of the lower crank-connecting rod stirring assembly 100b as follows: Figure 5The arrow indicates the direction of reciprocating rotation in both forward and reverse directions.

[0064] S4. The crank 160 of the lower crank-connecting rod stirring assembly 100b rotates while driving the connecting rod 150 to swing. The connecting rod 150 and the connecting plate 140 work together to drive multiple rocker arms 130 to swing around the rotation axis 120, ultimately achieving the rotation of the lower raw material bag 300 around the rotation axis 120. Figure 5 The arrow indicates the direction of the reciprocating swing;

[0065] This technology uses a crank-connecting rod stirring mechanism to drive the raw material bag 300 to swing back and forth continuously. This back-and-forth swinging stirs the raw materials inside the bag, thus preventing the raw materials from separating.

[0066] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0067] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
