[0002] A hot compress, also known as a heating patch or warming pad, is a product that releases heat through a chemical reaction. It is commonly used to relieve pain, ease muscle stiffness, and promote blood circulation.

[0003] The heat pack works by generating heat through the oxidation reaction of iron powder. It contains iron powder, activated carbon, inorganic salts (such as table salt), and water. When these ingredients come into contact with oxygen in the air, an oxidation reaction occurs, generating heat. This reaction is controllable and can be sustained over time, providing users with a consistent and stable heat experience.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0019] like Figure 1-Figure 7 As shown, in some embodiments, a raw material mixing device for producing hot compress bags includes a frame 1, a stirring component 2, and a mixing component 3. The frame 1 serves as the support base of the entire device, providing a stable support base for the stirring component 2 and the mixing component 3, ensuring stable operation of the entire device.

[0020] Specifically, both ends of the stirring assembly 2 are securely connected to the frame 1 via connectors, ensuring stable operation of the stirring assembly 2. The stirring assembly 2 is connected to the mixing assembly 3, allowing for free rotation between them. In particular, the stirring assembly 2 and the mixing assembly 3 rotate in opposite directions, achieving full mixing of the hot compress ingredients and ensuring efficient mixing.

[0021] It is worth noting that the stirring assembly 2 is equipped with a stirring shaft 21 and stirring paddles 22. There are multiple stirring paddles 22, which are arranged on the stirring shaft 21 at regular intervals to form an array, ensuring uniformity during the mixing process. The mixing assembly 3, on the other hand, is equipped with a mixing hopper 32 and auxiliary strips 33. The stirring shaft 21 passes through the center of the mixing hopper 32, allowing the stirring paddles 22 to be located within the mixing hopper 32. The auxiliary strips 33 are arranged within the mixing hopper 32 and are divided into two groups, and these two groups of auxiliary strips 33 are symmetrically distributed within the mixing hopper 32.

[0022] As the stirring paddle 22 rotates, the mixing bin 32 also rotates in the opposite direction of the stirring paddle 22, ensuring that the stirring paddle 22 is tangential to the auxiliary strips 33 during rotation, thereby effectively shearing and mixing the hot compress bag ingredients, ensuring the uniformity of the hot compress ingredients and the quality of the mixing. This design ensures that the ingredients are fully contacted and mixed during the mixing process, improving the mixing efficiency and quality of the hot compress bag ingredients.

[0023] It should be noted that when the mixing bin 32 is stationary, there will be two working positions, one is the loading position and the other is the unloading position. The loading position is set upward, while the unloading position is set downward. When in the loading position, after the hot compress raw materials are put into the mixing bin 32 in proportion, the mixing bin 32 is closed, and the power component 4 is started to drive the stirring component 2 and the mixing component 3 to rotate respectively. While the mixing component 3 is rotating, the auxiliary strips 33 carry the raw materials in the mixing bin 32 upward, and the raw materials fall at the highest point. Under the joint action of the stirring paddle 22 and the auxiliary strips 33, the hot compress raw materials are fully mixed, thereby improving the mixing effect and quality. When the raw materials are mixed, the mixing component 3 is rotated to the unloading position, where the raw materials are unloaded.

[0024] like Figure 5 、 Figure 6 As shown, in some embodiments, the frame 1 includes a support plate 11 and a bottom plate 15. The support plates 11 are arranged at both ends of the bottom plate 15, and support holes 12 are provided on the support plates 11. The two ends of the stirring shaft 21 are connected to the support holes 12 to form a stable support structure with the support plates 11.

[0025] A limiting telescopic rod 13 is provided on the inner side of the supporting vertical plate 11, and the limiting telescopic rod 13 is used to connect with the mixing component 3. When loading and unloading the mixing bin 32, the mixing component 3 is fixed by the limiting telescopic rod 13. When mixing and stirring are required, the limiting telescopic rod 13 is disconnected from the mixing component 3, so that the mixing component 3 can rotate smoothly.

[0026] Furthermore, a support frame 14, slide rails 16, and columns 17 are provided on the base plate 15. The support frame 14 is mounted on one side of the base plate 15 and is connected to the power assembly 4. The slide rails 16 are connected to the external discharge frame to facilitate the smooth transfer of the mixed raw materials.

[0027] In order to further improve the stability and load-bearing capacity of the device, two columns 17 are respectively provided on both sides of the slide rail 16. The tops of these columns 17 are also equipped with support wheels 18, which can be slidably connected to the outer wall of the stirring assembly 2, thereby providing smooth and stable support during the stirring process, ensuring a smooth stirring process.

[0028] like Figure 7As shown, in some embodiments, an end plate 23 is provided at one end of the agitator shaft 21. This end plate 23 is connected to the outer side of the support plate 11 to ensure the stability of the agitator shaft 21. This design ensures that the agitator shaft 21 remains stable during operation and does not experience unnecessary shaking or deviation due to external forces, thereby ensuring the reliability of the mixing process. In addition, a transmission wheel 24 is provided at the other end of the agitator shaft 21 to drive the agitator shaft 21 to rotate, ensuring stable rotation of the agitator shaft 21.

[0029] The stirring paddle 22 is tightly and securely connected to the outside of the stirring shaft 21, preventing the stirring paddle 22 from loosening or falling off the stirring shaft 21 during the stirring process, thereby ensuring the stability and reliability of the stirring effect. In addition, a drop hole 25 is provided between the stirring paddle 22 and the stirring shaft 21. The design of the drop hole 25 allows the raw materials to be quickly dispersed and fully mixed, avoiding accumulation or uneven distribution of raw materials between the stirring paddles 22, thereby significantly improving the uniformity and efficiency of mixing.

[0030] like Figure 4 and Figure 5 In some embodiments, the mixing bin 32 is disposed within the mixing barrel 31. Specifically, the mixing barrel 31 includes two first shells 311 and a second shell 312, with the two first shells 311 disposed at either end of the second shell 312. To ensure structural stability, the first shell 311 and the second shell 312 are fixedly connected together, forming a single unit.

[0031] Furthermore, to achieve effective mixing, each first housing 311 is connected to a stirring shaft 21, which is driven by a power assembly 4 to thoroughly mix the raw materials within the mixing bin 32. To further enhance the mixing effect, auxiliary strips 33 are welded to the inner wall of the second housing 312. These auxiliary strips 33 cooperate with the stirring paddle 22 to break up raw material clumps during mixing and promote uniform mixing.

[0032] Furthermore, in some embodiments, the mixing assembly 3 further includes a limiting sleeve 34, a material port 35, and a transmission rack 36. The transmission rack 36 is disposed on the outer wall of the second housing 312 and is welded thereto to ensure a stable connection between the transmission rack 36 and the second housing 312. The material port 35 is located in the center of the second housing 312. Raw materials can enter the mixing hopper 32 through the material port 35, where they are mixed and stirred. After the mixing process is complete, the raw materials are discharged through the same material port 35.

[0033] Two sets of limiting sleeves 34 are provided, one on each side of the two first housings 311. Each set of limiting sleeves 34 has two, and the symmetrical arrangement of the two limiting sleeves 34 ensures balance and stability. The limiting sleeves 34 correspond to the limiting telescopic rods 13. This correspondence enables them to work together to effectively control the position of the mixing barrel 31, facilitating the loading and unloading of raw materials.

[0034] Furthermore, in some embodiments, the raw material mixing device also includes a power assembly 4, which is connected to the frame 1. The power assembly 4 includes a first drive motor 41 and a second drive motor 42. Specifically, the first drive motor 41 is connected to the drive wheel 24 of the stirring shaft 21 through a transmission mechanism, ensuring that the stirring shaft 21 can be driven and rotated. The output end of the second drive motor 42 is equipped with a drive wheel 43, which is closely matched with the transmission rack 36, so that the second drive motor 42 can drive the mixing assembly 3 to rotate.

[0035] Furthermore, to ensure the stability and reliability of the power assembly 4, the first drive motor 41 is securely connected to the base plate 15, while the second drive motor 42 is securely connected to the support frame 14. This design not only ensures a secure connection between the motor and the frame 1, but also ensures that the power assembly 4 can efficiently and stably provide power during the mixing process, thereby ensuring the quality and efficiency of raw material mixing.

[0036] like Figure 4 As shown, in some embodiments, each set of auxiliary strips 33 includes multiple auxiliary strips 33, each designed with a sharp, tooth-like cross-section to facilitate gripping and mixing of raw materials. Furthermore, these auxiliary strips 33 are intentionally positioned toward the feed opening 35 to ensure smooth passage of raw materials from the auxiliary strips 33 and uniform mixing. These sharp, tooth-like auxiliary strips 33 effectively prevent clumping during mixing, ensuring fluidity and ensuring a more thorough and uniform mixing process.

[0037] The typical working process of the above embodiment is as follows: Loading stage: First, the second drive motor 42 is activated, which drives the drive wheel 43 to begin rotating. The rotating drive wheel 43, via the transmission rack 36, in turn rotates the mixing hopper 31, ensuring that the opening of the material port 35 faces upward. During this process, the telescopic limit rod 13 extends forward, its front end inserted into the limit sleeve 34. This serves to secure the mixing hopper 31 and prevent any displacement. Subsequently, the raw materials are added to the mixing hopper 32 according to the predetermined ratio. Once the materials are added, the material port 35 is closed.

[0038] Mixing and stirring stage: Next, the telescopic limit rod 13 retracts backward, releasing the mixing drum 31 and allowing it to rotate freely. The first and second drive motors 41, 42 are then activated, respectively driving the agitator shaft 21 and the mixing drum 31 to rotate in the predetermined direction. During this rotation, the raw materials within the mixing drum 31 are thoroughly stirred and mixed through the interaction of the agitator paddles 22 and the auxiliary strips 33. Simultaneously, as the mixing drum 31 rotates, the support wheels 18 contact the outer wall of the mixing drum 31, providing support from below and ensuring its stability. The support wheels 18 also rotate as the mixing drum 31 rotates.

[0039] Unloading stage: After the raw materials are thoroughly mixed, the next step is unloading. At this point, adjust the material opening 35 to a downward-facing position. Similar to the loading phase, the telescopic limit rod 13 and the limit sleeve 34 cooperate to secure the mixing barrel 31. Then, slide the external unloading frame below the material opening 35 via the slide rails 16. Opening the material opening 35 allows the raw materials to fall from the mixing barrel 31 into the unloading frame below.

[0040] The above description is the entire mixing operation process of the hot compress bag raw materials. By repeating the above steps, the raw materials can be mixed continuously.

[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
