Description

Technical Field

[0001] This utility model relates to the technical field of chocolate melting cylinders, specifically to a height-adjustable chocolate melting cylinder. Background Technology

[0002] The main function of a melting tank is to provide a stable heat source so that the chocolate raw materials melt evenly at a set temperature. It is an indispensable piece of equipment in the chocolate making process, which can ensure the quality and taste of the chocolate. In the chocolate production process, the melting tank is usually used in conjunction with a stirrer to melt the chocolate.

[0003] In the process of melting chocolate in existing melting tanks, different chocolate ingredients (such as cocoa butter, sugar, milk powder, etc.) may separate or clump due to differences in physical properties such as density and viscosity. Therefore, the mechanical action of the stirrer can fully stir these ingredients to achieve a uniform mixture, thereby ensuring the consistency of the chocolate's taste and quality. The stirrer plays a crucial role in the chocolate melting tank.

[0004] For example, the precise temperature-controlled chocolate melting device disclosed in patent CN213939595U, although the motor drives the stirring shaft and fan blades to rotate when heating the chocolate to make the chocolate stir and heat it evenly, the stirring shaft, stirring rod, and fan blades are all welded to the rotating shaft. This means that they are a whole and cannot be easily disassembled. After long-term use, especially when dealing with highly viscous chocolate, chocolate residue is easy to remain on the stirring rod and fan blades, which is difficult to clean. Long-term incomplete cleaning may lead to a large amount of dirt accumulating on the stirring components, which not only affects the stirring efficiency but may also have a negative impact on the quality of the chocolate. If the dirt is so severe that it cannot be cleaned, the entire stirring component may need to be replaced, increasing maintenance costs.

[0005] Therefore, it is necessary to invent a lifting and lowering melting cylinder for chocolate production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a height-adjustable melting cylinder for chocolate production, in order to solve the problem that the mixer cannot be easily disassembled and is inconvenient to clean.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable melting cylinder for chocolate production, comprising a base and a stirrer. An outer cylinder is provided on the upper front side of the base, and an inner cylinder is provided inside the outer cylinder. A column is provided on the upper rear side of the base, and a Y-axis sliding assembly is provided on the front side of the column. A Y-axis sliding sleeve is slidably mounted on the Y-axis sliding assembly. A servo motor is provided on the front side of the Y-axis sliding sleeve, and a bushing is connected to the output end of the servo motor. A rotating shaft is provided below the bushing, and a connecting rod is connected to the top of the rotating shaft. The connecting rod is located inside the bushing. A fixing bolt is provided on the outside of the bushing and extends through the connecting rod to the outside. A nut is provided on the fixing bolt. Clamps are provided on the left and right sides of the outer cylinder.

[0008] Preferably, there is a gap between the inner wall of the outer cylinder and the outer wall of the inner cylinder. A first electric heating tube is provided at the bottom of the inner cylinder, and a second electric heating tube is provided on the outer wall of the inner cylinder. Both the first and second electric heating tubes are in contact with the outer wall of the inner cylinder, thereby achieving efficient heating of the chocolate raw materials inside the inner cylinder.

[0009] Preferably, the bushing and the connecting rod are connected by a thread, and the thread on the outer wall of the bushing matches the thread on the inner wall of the connecting rod, making the connection between the rotating shaft and the agitator more stable and reliable, while also facilitating disassembly and assembly.

[0010] Preferably, the rotating shaft is provided with a sealing cover, which is located at the top of the inner cylinder. The sealing cover and the inner cylinder are connected by a snap-fit ​​connection. The sealing cover can prevent external impurities from entering the inner cylinder and also prevent chocolate raw materials from splashing or leaking out of the inner cylinder during the stirring process, thus ensuring the purity of the chocolate raw materials.

[0011] Preferably, a stirrer is provided at the bottom of the rotating shaft. The stirrer is located inside the inner cylinder and can evenly stir the chocolate raw materials, making them heat more evenly and melt faster.

[0012] Preferably, the fixing bolt and the nut are connected by threads, and the outer thread of the fixing bolt and the inner thread of the nut cooperate to further strengthen the connection and prevent loosening or falling off during the stirring process.

[0013] Preferably, a mounting frame is provided on the front wall below the column, and connecting arms are provided on both sides of the mounting frame. One end of the connecting arm is movably installed inside the mounting frame, and a cylinder is provided between the connecting arm and the mounting frame. One end of the cylinder is hinged inside the mounting frame, and the other end of the cylinder is hinged inside the connecting arm. The expansion movement of the connecting arm is realized by driving the cylinder, thereby adjusting the clamping or loosening of the outer cylinder of the clamp.

[0014] Preferably, the other end of the connecting arm is provided with a clamp, and two clamps are provided. The silicone pads on the inner walls of the two clamps are in contact with the outer wall of the outer cylinder, so that the two clamps can stably hold the outer cylinder.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model utilizes the combination of the Y-axis sliding component and the Y-axis sliding sleeve to provide a stable and precise lifting path for the servo motor and the stirrer. As a result, the stirrer can be adjusted in height. The height control of the stirrer allows the stirrer to stir at a specified height, ensuring the uniformity and consistency of the stirring.

[0017] 2. This utility model uses a connecting rod to thread the rotating shaft onto the bushing, and reinforces it with fixing bolts and nuts. When it is necessary to disassemble the agitator for cleaning, simply loosen the fixing bolts and nuts first, and then rotate the connecting rod to gradually unscrew the rotating shaft from the bushing. This allows the operator to easily disassemble the agitator for thorough cleaning or maintenance. The entire process requires no complicated tools or skills; it can be done simply by following the rotation direction of the thread. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The illustrated lifting melt cylinder for chocolate production includes a base 1 and a stirrer 13. An outer cylinder 2 is located on the upper front side of the base 1, and an inner cylinder 3 is located inside the outer cylinder 2. A column 6 is located on the upper rear side of the base 1. A Y-axis sliding assembly 7 is located on the front side of the column 6. A Y-axis sliding sleeve 8 is slidably mounted on the Y-axis sliding assembly 7. A servo motor 9 is located on the front side of the Y-axis sliding sleeve 8. The output end of the servo motor 9 is connected to a bushing 10. A rotating shaft 11 is located below the bushing 10. A connecting rod 14 is connected to the top of the rotating shaft 11. The connecting rod 14 is located inside the bushing 10. A fixing bolt 15 is located on the outside of the bushing 10 and extends through the connecting rod 14 to the outside. A nut 16 is located on the fixing bolt 15. Clamps 20 are located on the left and right sides of the outer cylinder 2.

[0028] There is a gap between the inner wall of the outer cylinder 2 and the outer wall of the inner cylinder 3. The bottom of the inner cylinder 3 is provided with a first electric heating tube 4, and the outer wall of the inner cylinder 3 is provided with a second electric heating tube 5. Both the first electric heating tube 4 and the second electric heating tube 5 are in contact with the outer wall of the inner cylinder 3.

[0029] The outer cylinder 2 serves as a container for the inner cylinder 3. There is an appropriate gap between the inner wall of the outer cylinder 2 and the outer wall of the inner cylinder 3 to facilitate heat transfer and heat preservation. The inner cylinder 3 is used to directly hold chocolate raw materials. The first electric heating tube 4 at the bottom of the inner cylinder 3 is used to heat the chocolate raw materials from the bottom. At the same time, the second electric heating tube 5 on the outer wall of the inner cylinder 3 further ensures the uniform transfer of heat and the rapid melting of the chocolate raw materials. The combination of the first electric heating tube 4 and the second electric heating tube 5 improves the heating efficiency.

[0030] The bushing 10 and the connecting rod 14 are connected by threads. The threads on the outer wall of the bushing 10 are engaged with the threads on the inner wall of the connecting rod 14. A sealing cover 12 is provided on the rotating shaft 11. The sealing cover 12 is located at the top of the inner cylinder 3 and is engaged with the inner cylinder 3. A stirrer 13 is provided at the bottom of the rotating shaft 11 and is located inside the inner cylinder 3. The fixing bolt 15 and the nut 16 are connected by threads. The threads on the outer wall of the fixing bolt 15 are engaged with the threads on the inner wall of the nut 16.

[0031] The bushing 10 and the connecting rod 14 are connected by threads. By tightening the fixing bolts 15 and nuts 16, a stable connection between the rotating shaft 11 and the stirrer 13 can be ensured. This connection method is convenient for disassembly and maintenance. The sealing cover 12 and the inner cylinder 3 are connected by a snap-fit ​​connection to prevent chocolate raw materials from splashing out during the stirring process. The stirrer 13 is driven by the servo motor 9 and the rotating shaft 11 to rotate, thereby achieving uniform stirring of the chocolate raw materials.

[0032] A mounting bracket 17 is provided on the front wall below the column 6. Connecting arms 18 are provided on both sides of the mounting bracket 17. One end of the connecting arm 18 is movably installed inside the mounting bracket 17. A cylinder 19 is provided between the connecting arm 18 and the mounting bracket 17. One end of the cylinder 19 is hinged inside the mounting bracket 17, and the other end of the cylinder 19 is hinged inside the connecting arm 18. A clamp 20 is provided on the side wall of the other end of the connecting arm 18. Two clamps 20 are provided. The silicone pads on the inner walls of the two clamps 20 are in contact with the outer wall of the outer cylinder 2.

[0033] Driven by the cylinder 19, the connecting arm 18 can smoothly open and close to the left and right or clamp, thereby enabling the clamp 20 to clamp and release the outer cylinder 2. The silicone pad on the inner wall of the clamp 20 not only increases the friction with the outer wall of the outer cylinder 2, but also plays a role in buffering and protection, preventing damage to the outer cylinder 2 during clamping. Therefore, when it is necessary to clean the outer cylinder 2, the clamp 20 can be released by the extension movement of the cylinder 19, and the outer cylinder 2 can be easily removed, which facilitates the cleaning of the inner cylinder 3 inside the outer cylinder 2, greatly improving the cleaning efficiency and convenience of the equipment.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-3When using this invention, first pour the chocolate raw material into the inner cylinder 3, then start the Y-axis sliding assembly 7. The Y-axis sliding sleeve 8 can then slide on the Y-axis sliding assembly 7, causing the Y-axis sliding sleeve 8 to drive the stirrer 13 downwards until the stirrer 13 is completely immersed in the chocolate raw material in the inner cylinder 3. Simultaneously, as the stirrer 13 descends, the sealing cap 12 also descends and tightly seals the opening of the inner cylinder 3. After the sealing cap 12 is closed, start the device. With the heating of the first electric heating tube 4 and the second electric heating tube 5, the chocolate raw material in the inner cylinder 3 begins to gradually melt, and the heat is transferred through the inner cylinder... The wall of cylinder 3 transmits the chocolate. When the chocolate begins to melt, the servo motor 9 is started. The output end of the servo motor 9 is connected to the rotating shaft 11 through the bushing 10 and the connecting rod 14, driving the rotating shaft 11 to rotate. The stirrer 13 at the bottom of the rotating shaft 11 rotates accordingly, stirring the melted chocolate evenly until the chocolate is completely melted and reaches the required uniformity. When the chocolate is completely melted and reaches the required uniformity, the power to the servo motor 9, the first electric heating tube 4, and the second electric heating tube 5 is turned off. Then, the stirrer 13 is lifted out of the inner cylinder 3 through the Y-axis sliding assembly 7 and the Y-axis sliding sleeve 8.

[0036] Refer to the instruction manual appendix Figure 4-6 When using this invention, if it is necessary to clean the agitator 13 and the inner wall of the inner cylinder 3, first loosen the fixing bolts 15 and nut 16, then loosen the threaded connection between the bushing 10 and the connecting rod 14, thereby removing the connecting rod 14 from the bushing 10. This achieves the disassembly and cleaning of the agitator 13. When the cleaned agitator 13 needs to be installed, simply align the bushing 10 with the connecting rod 14 and fix it to the connecting rod 14 using the threaded connection. Then tighten the fixing bolts 15 and nut 16 to ensure a tight and reliable connection between the bushing 10 and the connecting rod 14. When cleaning the inner cylinder 3, the cylinder 19 can be activated. The cylinder 19 extends, pulling the connecting arm 18 to rotate in the opposite direction around the fixed point, causing the two clamps 20 to open outward and release the clamping force on the outer cylinder 2. At this time, the operator can easily remove the outer cylinder 2. When the cleaned inner cylinder 3 needs to be fixed on the base 1, simply activate the cylinder 19 to retract, pushing the connecting arm 18 to rotate around the fixed point, causing the two clamps 20 to move closer to the center and clamp the outer cylinder 2. The friction of the silicone pad ensures that the outer cylinder 2 is firmly fixed in place, preventing shaking during stirring or heating.
