Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, and in particular to a self-heating mixing device for packaging. Background Technology

[0002] Self-heating food, as a new type of convenient food, is increasingly favored by the public due to its convenience and efficiency. The core technology of self-heating food lies in its built-in self-heating pack, which allows for rapid heating of food through simple operation. To use it, simply pour water into the self-heating pack; the materials inside react chemically with the water, rapidly releasing a large amount of heat, causing the water to boil and generate steam, thus heating the food to a suitable temperature in a short time. This heating method requires no external heat source, making it particularly suitable for outdoor activities, travel, or emergency situations.

[0003] In the production of self-heating packs, materials such as quicklime, sodium bicarbonate, and magnesium sulfate need to be mixed evenly in a specific ratio to ensure consistent heating performance in each pack. However, quicklime is highly hygroscopic, easily absorbing moisture from the air during mixing, leading to clumping. Furthermore, the calcium hydroxide produced by the reaction of quicklime with water is sticky and easily adheres to the inner walls of the mixing equipment, forming hard lumps. These lumps not only affect the mixing effect but also reduce production efficiency and may even damage the equipment.

[0004] Therefore, it is necessary to clean the clumps on the inner wall of the mixing equipment regularly. However, due to the obstruction of the mixing blade in the mixing chamber, users face difficulties in cleaning the clumps on the inner wall of the mixing chamber, resulting in low cleaning efficiency. Utility Model Content

[0005] In view of this, the present invention aims to provide a self-heating pack mixing device to improve the cleaning efficiency of the mixing chamber.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A self-heating pack processing mixing device includes a support frame, a mixing chamber, and a mixing paddle;

[0008] The mixing chamber includes a first chamber body fixedly connected to the bracket, and a second chamber body detachably connected to the first chamber body. The first chamber body and the second chamber body form a "U"-shaped mixing cavity with an opening at the top.

[0009] The stirring paddle is rotatably connected to the first chamber, and the second chamber is connected to the first chamber along the axial direction of the stirring paddle; the second chamber is provided with a rotating support for supporting the stirring paddle, and when the first chamber is connected to the second chamber, one end of the stirring paddle passes through the rotating support.

[0010] Furthermore, the bracket is disposed on a working plane;

[0011] The second compartment is equipped with rollers, and the second compartment can slide on the working plane via the rollers to move closer to or further away from the first compartment.

[0012] Furthermore, the bracket is provided with a sliding groove, and the second compartment is provided with a sliding strip, which is slidably disposed within the sliding groove.

[0013] Furthermore, the first compartment is a plate-like structure in the shape of an inverted arch;

[0014] The second chamber has an opening at one end facing the first chamber, so that the agitator can be moved out of the second chamber when the second chamber is away from the first chamber.

[0015] Furthermore, the second compartment is provided with a connecting plate bent outward at one end facing the first compartment, and the connecting plate is connected to the first compartment by bolts and nuts.

[0016] Furthermore, a sealing strip is sandwiched between the first compartment and the connecting plate.

[0017] Furthermore, the first compartment body and the connecting plate are provided with a waist-shaped hole, one end of which is expanded to form a round hole through which the nut of the bolt passes.

[0018] Furthermore, the stirring paddle includes a rotating shaft and multiple sets of stirring blades connected to the rotating shaft;

[0019] The stirring blade includes a blade, a fixing rod, and a connecting plate; the connecting plate is bolted to the rotating shaft, and the connecting plates of the stirring blades in the same group surround the circumferential outer wall of the rotating shaft; the fixing rod is fixedly connected to the blade and the connecting plate.

[0020] Furthermore, the self-heating pack processing mixing device also includes a cover, which can seal the top opening of the mixing chamber.

[0021] Furthermore, the self-heating pack processing mixing device also includes a drive unit disposed on the support, the drive unit including a motor and a reducer, the reducer being connected between the motor and the stirring paddle.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The self-heating pack processing mixing device of this utility model, by setting a detachably connected first chamber and a second chamber, can separate the second chamber from the first chamber when cleaning of the mixing chamber is required, and the stirring paddle can be separated from the second chamber to facilitate the cleaning of the clumps on the inner wall of the second chamber. Without the obstruction of the stirring paddle, the cleaning time can be shortened, thereby improving the cleaning efficiency.

[0024] Secondly, rollers are installed on the second chamber, which support it and facilitate its movement for connection or separation from the first chamber, improving the ease of assembly and disassembly. Slide grooves are provided on the support frame, and slide bars are installed on the second chamber to guide its movement, ensuring a more accurate connection between the second and first chambers. Designing the first chamber as a plate distributes most of the inner wall of the mixing chamber onto the second chamber, facilitating cleaning of the mixing chamber's inner wall after the agitator detaches from the second chamber.

[0025] Secondly, the connecting plate facilitates the connection between the first and second chambers, and the use of bolts and nuts ensures a more secure fixation. A sealing strip between the first and second chambers improves the seal, preventing material leakage from the mixing chamber. The oblong holes on the first and connecting plates, with one end expanded into a round hole, facilitate the installation of bolts and nuts, allowing for easy assembly and disassembly of the first and connecting plates without unscrewing the bolts.

[0026] Furthermore, by surrounding the agitator blades with connecting plates and connecting them to the shaft with bolts, the installation of the agitator blades is facilitated. Additionally, a set of connecting plates can be assembled into a complete ring, improving the overall structural strength of the agitator blades. The machine cover prevents internal dust from escaping into the surrounding environment during mixing operations. The motor and reducer ensure a relatively stable drive for the rotation of the agitator blades. Attached Figure Description

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This embodiment relates to a self-heating pack processing mixing device to improve the cleaning efficiency of the mixing chamber.

[0050] In terms of overall structure, refer to Figures 1 to 3 As shown, the self-heating pack processing mixing device of this embodiment includes a support 1, a mixing chamber 2, and a mixing paddle 3. The mixing chamber 2 includes a first chamber body 201 fixedly connected to the support 1, and a second chamber body 202 detachably connected to the first chamber body 201. The first chamber body 201 and the second chamber body 202 form a "U"-shaped mixing chamber with an open top.

[0051] The stirring paddle 3 is rotatably connected to the first chamber 201, and the second chamber 202 is connected to the first chamber 201 along the axial direction of the stirring paddle 3. The second chamber 202 is provided with a rotating support 4 for supporting the stirring paddle 3. When the first chamber 201 is connected to the second chamber 202, one end of the stirring paddle 3 passes through the rotating support 4.

[0052] As configured above, the self-heating pack processing mixing device of this embodiment, by providing a detachably connected first chamber 201 and second chamber 202, can separate the second chamber 202 from the first chamber 201 when cleaning of the mixing chamber is required, and the stirring paddle 3 can be disengaged from the second chamber 202 to facilitate the cleaning of the clumps on the inner wall of the second chamber 202. Without the obstruction of the stirring paddle 3, the cleaning time can be shortened, thereby improving the cleaning efficiency.

[0053] Based on the above overall introduction, specifically, in this embodiment, the top opening of the mixing chamber 2 is the feed inlet, and the bottom is provided with a chamber door 2024. Raw materials such as quicklime, sodium bicarbonate and magnesium sulfate are added to the mixing chamber 2, and after being mixed evenly, they are discharged through the discharge door and transported by the transport device to the subsequent bagging process.

[0054] The bracket 1 is mounted on a working plane. To facilitate the movement of the second compartment 202, the second compartment 202 is equipped with rollers 2021, and the second compartment 202 can slide on the working plane via the rollers 2021 to move closer to or away from the first compartment 201. The rollers 2021 on the second compartment 202 support the second compartment 202 and also facilitate its movement to connect or separate from the first compartment 201, improving the ease of assembly and disassembly of the second compartment 202. In this embodiment, the second compartment 202 has a portal frame fixed on each side, and the bottom end of the portal frame legs is equipped with rollers 2021. Each portal frame has two rollers 2021 to facilitate the movement of the second compartment 202.

[0055] Furthermore, in order to improve the accuracy of the connection position between the second compartment 202 and the first compartment 201, refer to Figure 3 and Figure 4 As shown, the bracket 1 in this embodiment is provided with a sliding groove 101, and the second compartment 202 is provided with a sliding strip 2022, which is slidably disposed within the sliding groove 101. Providing the sliding groove 101 on the bracket 1 and the sliding strip 2022 on the second compartment 202 guides the movement of the second compartment 202, making the connection position between the second compartment 202 and the first compartment 201 more accurate. Specifically, there are two sliding grooves 101, located on both sides of the first compartment 201, with the openings of the sliding grooves 101 facing downwards; there are two sliding strips 2022, located on both sides of the second compartment 202, and slidably connected to the corresponding sliding grooves 101, and suspended within the sliding grooves 101.

[0056] Secondly, regarding the specific structure of the first chamber 201 and the second chamber 202, in this embodiment, the first chamber 201 is a plate-shaped inverted arch. The second chamber 202 has an opening at one end facing the first chamber 201, allowing the stirring paddle 3 to be moved out of the second chamber 202 when the second chamber 202 is away from the first chamber 201. By setting the first chamber 201 as a plate, the cavity wall of the stirring chamber around the stirring paddle 3 is all on the second chamber 202, thereby distributing most of the inner wall of the stirring chamber onto the second chamber 202, which facilitates the cleaning of the inner wall of the stirring chamber after the stirring paddle 3 is removed from the second chamber 202.

[0057] To facilitate the connection between the first compartment 201 and the second compartment 202, a connecting plate 2023 is provided at the end of the second compartment 202 facing the first compartment 201, bent outwards. The connecting plate 2023 is connected to the first compartment 201 by bolts and nuts. The connecting plate 2023 facilitates the connection between the first compartment 201 and the second compartment 202, increases the contact area at the connection point, and provides a more secure fixation when used with bolts and nuts.

[0058] Furthermore, to improve the sealing between the first chamber 201 and the second chamber 202, a sealing strip 7 is sandwiched between the first chamber 201 and the connecting plate 2023. The sealing strip 7 between the first chamber 201 and the connecting plate 2023 improves the sealing between them, making it less likely for material to leak from the mixing chamber. In this embodiment, the sealing strip 7 is U-shaped and adhered to the inner side of the first chamber 201. When the second chamber 202 connects to the first chamber 201, the first chamber 201 and the connecting plate 2023 together compress the sealing strip 7 to achieve a sealing effect.

[0059] Preferably, to facilitate the assembly and disassembly of the first compartment 201 and the second compartment 202, refer to Figures 1 to 3 As shown, a waist-shaped hole 203 is provided through the first chamber 201 and the connecting plate 2023. One end of the waist-shaped hole 203 expands to form a round hole 204 for the bolt nut to pass through. The waist-shaped hole 203 on the first chamber 201 and the connecting plate 2023, with the round hole 204 expanding at one end, facilitates the installation of the bolt and nut, allowing the nut to be installed and removed from the first chamber 201 and the connecting plate 2023 without having to unscrew it from the bolt. The waist-shaped hole 203 and the round hole 204 are arranged on the first chamber 201 and the connecting plate 2023 outside the sealing strip 7, along the arrangement direction of the sealing strip 7. The round hole 204 is located at the higher end of the waist-shaped hole 203, so that the combination of the bolt and nut, under its own weight, has a component force away from the round hole 204, making it less likely to loosen from the round hole 204 after being securely tightened.

[0060] For details regarding the structure of the agitator 3, please refer to... Figure 3 and Figure 5 As shown, the impeller 3 includes a rotating shaft 302 and multiple sets of stirring blades 301 connected to the rotating shaft 302. Each stirring blade 301 includes blades 3011, a fixing rod 3012, and a connecting piece 3013. The connecting piece 3013 is bolted to the rotating shaft 302. The connecting pieces 3013 of the same set of stirring blades 301 surround the circumferential outer wall of the rotating shaft 302. The fixing rod 3012 fixes the blades 3011 and the connecting piece 3013. By surrounding the connecting piece 3013 of the stirring blades 301 on the rotating shaft 302 and connecting it to the rotating shaft 302 with bolts, the installation of the stirring blades 301 is facilitated. Furthermore, the connecting pieces 3013 of a set of stirring blades 301 can be assembled into a complete ring, improving the overall structural strength of the stirring blades 301.

[0061] Specifically, in this embodiment, the rotating shaft 302 is provided with two sets of stirring blades 301, with two blades 301 in each set. The blades 3011 are spiral-shaped, and the connecting pieces 3013 are semi-circular. The three connecting pieces 3013 and the three fixing rods 3012 are connected to one blade 3011. The two semi-circular connecting pieces 3013 of the same set of stirring blades 301 are assembled together to form a complete ring. The installation direction of the bolts on the connecting pieces 3013 is the same as the direction in which the connecting pieces 3013 are fastened to the rotating shaft 302, so as to press the two connecting pieces 3013 together.

[0062] Furthermore, to make the mixing process more closed, refer to Figure 1 As shown, the self-heating pack processing mixing device also includes a cover 5, which can seal the top opening of the mixing chamber 2. The cover 5 can prevent internal dust from escaping into the surrounding environment during the mixing operation, and can also prevent external debris from flying into the mixing chamber. The cover 5 can be fixed to the mixing chamber 2 with buckles for easy installation and removal.

[0063] Additionally, regarding the source of power for the rotation of the agitator 3, please refer to... Figure 3 As shown, the self-heating pack processing mixing device also includes a drive unit 6 mounted on the support 1. The drive unit 6 includes a motor 601 and a reducer 602, with the reducer 602 connected between the motor 601 and the stirring blade 3. The motor 601 and reducer 602 enable the stirring blade 301 to rotate relatively stably, while the reducer 602 absorbs some vibration, reducing the vibration force on the output shaft of the motor 601.

[0064] The self-heating pack processing mixing device of this embodiment, by setting a detachably connected first chamber 201 and second chamber 202, can separate the second chamber 202 from the first chamber 201 when it is necessary to clean the mixing chamber, and the stirring paddle 3 can be disengaged from the second chamber 202 to facilitate the cleaning of the clumps on the inner wall of the second chamber 202. Without the obstruction of the stirring paddle 3, the cleaning time can be shortened, thereby improving the cleaning efficiency.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
