Description

Technical Field

[0001] This application relates to the technical field of food processing machinery, and in particular to the punching mechanism of a milk candy machine. Background Technology

[0002] Currently, with the development of the social economy and the improvement of people's living standards, the demand for milk candy continues to grow. Consumers have higher requirements for the taste and appearance quality of milk candy, which prompts the milk candy production industry to continuously innovate and improve production processes and equipment. As a core piece of equipment, the performance of the milk candy machine is crucial. Advanced milk candy machines can achieve highly automated production, improve efficiency, reduce human error and costs, accurately control the molding precision of milk candy, ensure consistent taste and appearance, and meet the diversified needs of the market. The die mechanism, as a key component of the milk candy machine, directly affects the shape, dimensional accuracy, and overall quality of the milk candy.

[0003] Traditional milk candy machine die-cutting mechanisms typically involve two sets of stamping rods on either side of the die cavity. These two sets are mounted on the same rotating frame and rotate synchronously. The end of the stamping rod closest to the die cavity is a die head that matches the contour of the candy's end face. It is slidably mounted on the frame along the circumferential direction and has a return spring between it and the frame. This allows the stamping rod to move away from the die cavity after completing the stamping. The side of the stamping rod furthest from the die cavity has a cam surface that moves from near to far. When rotating, the cam surface moves closer to the die cavity to complete continuous stamping, turning the soft candy raw material into a hard candy of a specific shape. Some traditional mechanisms also use mechanical transmission methods such as linkage mechanisms to drive the stamping rods to stamp. All of these designs are geared towards the purpose of stamping and shaping milk candy raw materials.

[0004] In traditional stamping die mechanisms, the stamping rod and the extrusion convex surface rub against each other continuously. Over time, this causes the stamping rod to wear down, resulting in changes in stroke and unstable stamping distance. This makes it difficult to ensure stamping consistency and accuracy, seriously affecting the quality of candy molding. The produced milk candies have large differences in shape and size, failing to meet high-quality uniform standards and reducing the product's market competitiveness. Summary of the Invention

[0005] In order to solve the above problems, this application provides a punching mechanism for a milk candy machine.

[0006] The die-punching mechanism of the milk candy machine provided in this application adopts the following technical solution: The punching mechanism of the milk candy machine includes a fixed frame, a rotating frame, a mold cavity, a punching assembly, and a contact disc. The rotating frame is rotatably connected to the fixed frame, and the mold cavity is fixedly connected to the rotating frame. Two sets of punching assemblies are provided and symmetrically distributed along the mold cavity. Each punching assembly includes multiple punching rods, which are spaced apart circumferentially along the mold cavity. The punching rods are slidably connected along the axial direction of the rotating frame. A reset assembly for driving the punching rods to reset is provided between the rotating frame and the punching rods. Mounting modules are provided at both ends of the punching rods. The mounting modules are fixedly connected to the fixed frame, and the contact disc is rotatably connected to the mounting modules. The multiple punching rods abut against the contact disc respectively.

[0007] By adopting the above technical solution, the rotating frame can rotate relative to the fixed frame, and the mold cavity rotates accordingly. The stamping components are symmetrically distributed on both sides of the mold cavity. The stamping rods are circumferentially spaced and can slide axially. The reset component can drive the stamping rods to reset. The abutting disc is rotatably connected to the mounting module and abuts against the stamping rods. This can convert the sliding friction between the stamping rods and the abutting discs into static friction, avoid the wear of the stamping rods, improve the stroke accuracy of the stamping rods, and make the stamped candies more uniform and standardized.

[0008] Optionally, the abutting disc is inclined, and its inclination angle is adapted to the sliding direction of the stamping rod. The end of the stamping rod away from the mold cavity abuts against the end face of the abutting disc, and the abutting disc rotates synchronously with the circumferential movement of the stamping rod.

[0009] By adopting the above technical solution, the sliding friction between the stamping rod and the abutting disc can be converted into static friction, reducing the friction between the two, reducing the wear of the stamping rod, ensuring the stroke accuracy of the stamping rod, and thus improving the molding quality of the candy.

[0010] Optionally, the abutting disc has a circular groove, the width of which is greater than the outer diameter of the end of the stamping rod away from the mold cavity, and the trajectory of the circular groove coincides with the movement trajectory of the end of the stamping rod.

[0011] By adopting the above technical solution, the circular groove provides movement space for the end of the stamping rod, avoiding unnecessary friction between the end of the stamping rod and the abutting disc, further reducing the wear of the stamping rod, and ensuring the stability of the candy molding quality.

[0012] Optionally, the end of the stamping rod near the abutting disc is provided with an arc-shaped protrusion, which is embedded in a circular groove and rolls in contact with the abutting disc.

[0013] By adopting the above technical solution, the arc-shaped protrusion changes the sliding contact between the stamping rod and the abutting disc to a rolling contact, further reducing the friction between the two, reducing the wear of the stamping rod, and better ensuring the stroke accuracy and service life of the stamping rod, thereby making the stamped candies more uniform and standardized.

[0014] Optionally, the mounting module is interference-fitted with a rotating bearing on the side away from the fixed frame, and the abutting disc is interference-fitted with the rotating bearing. A limiting ring is provided at the end of the central axis of the abutting disc away from the fixed frame to restrict the axial movement of the abutting disc.

[0015] By adopting the above technical solution, the abutment disc can rotate stably, avoiding axial movement, ensuring the stability of the fit between the abutment disc and the stamping rod, and further improving the stroke accuracy of the stamping rod and the quality of candy molding.

[0016] Optionally, the abutting disc is made of a wear-resistant material, and the mounting module is coated with a wear-resistant coating.

[0017] By adopting the above technical solution, the wear resistance of the contact disc and the mounting module is improved, and the service life of the contact disc and the mounting module is effectively extended.

[0018] Optionally, the reset assembly includes a reset spring and a spring retaining ring. The spring retaining ring is fixed to the rotating frame. An annular step is fixed circumferentially on the stamping rod. The reset spring is sleeved on the stamping rod, with one end of the reset spring abutting against the spring retaining ring and the other end abutting against the annular step.

[0019] By adopting the above technical solution, the automatic reset of the stamping rod can be achieved, ensuring that the stamping rod returns to its initial position after each stamping action, thus ensuring the continuous and stable operation of the stamping die mechanism.

[0020] Optionally, a circumferential shaping disc is coaxially fixed to the outer side of the rotating frame, and the inner ring of the circumferential shaping disc is in contact with the outer wall of the mold cavity.

[0021] By adopting the above technical solution, the circumferential shaping disc can position and support the mold cavity, ensuring the stability of the mold cavity during rotation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the abutting disc optimizes the cam abutting structure at both ends of the stamping rod, converting sliding friction into static friction, reducing stamping rod wear, and extending the service life of the stamping rod; 2. Ensure the accuracy of the stamping rod stroke and stabilize the stamping distance, making the shape and size of the milk candy more uniform and standardized, solving the wear problem caused by the friction between the stamping rod and the extrusion convex surface in the traditional stamping die mechanism, and improving the molding quality and market competitiveness of the milk candy.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0026] This application discloses a punching mechanism for a milk candy machine.

[0027] refer to Figure 1 and Figure 2 The die-cutting mechanism of the milk candy machine includes a fixed frame 1. Inside the fixed frame 1, there is a rotating frame 2, a die cavity 3, a stamping assembly 5, and an abutment disc 6. A drive shaft 11 is horizontally arranged inside the fixed frame 1. The drive shaft 11 is rotatably connected to the fixed frame 1 through bearings. The rotating frame 2, the die cavity 3, and the stamping assembly 5 are all fixedly connected to the drive shaft 11. A circumferential shaping disc 4 is also fixed around the die cavity 3. The inner ring of the circumferential shaping disc 4 fits against the outer wall of the die cavity 3, so that the rotating frame 2, the die cavity 3, the circumferential shaping disc 4, and the stamping assembly 5 all rotate relative to the fixed frame 1.

[0028] The stamping assembly 5 is provided in two sets and is symmetrically distributed along the mold cavity 3. The stamping assembly 5 includes multiple stamping rods 51, which are spaced apart along the circumference of the mold cavity 3. The multiple stamping rods 51 are combined to form an elliptical profile. The rotating frame 2 is provided with multiple sliding grooves in the circumference. The stamping rods 51 correspond to the sliding grooves and are slidably connected in the sliding grooves.

[0029] The stamping rod 51 has mounting modules 7 at both ends, which are fixedly connected to the fixed frame 1. The mounting module 7 itself has two mounting seats 71 of different lengths, and a rotating seat 72 is fixed between the two mounting seats 71. The rotating seat 72 is inclined. The abutting disc 6 and the rotating seat 72 are fixed with bolts, which facilitates disassembly, replacement and maintenance. In addition, the rotating seat 72 is equipped with a rotating bearing. One end of the rotating bearing is interference-fitted with the rotating seat 72, and the other end is interference-fitted with the abutting disc 6. A limit ring 721 is fixed at the end of the abutting disc 6 away from the rotating seat 72, which facilitates the rotation of the abutting disc 6 relative to the rotating seat 72 and prevents the abutting disc 6 from detaching from the rotating seat 72, thereby increasing the stability of the abutting disc 6.

[0030] refer to Figure 1 and Figure 2 The abutting disc 6 is inclined, and its inclination angle is adapted to the sliding direction of the stamping rod 51. A circular groove is opened on the circumferential side of the abutting disc 6. The width of the circular groove is greater than the outer contour diameter of the two ends of the stamping rod 51. The two ends of the stamping rod 51, that is, the ends away from the mold cavity 3, are set as arc-shaped protrusions and the surface is coated with wear-resistant material. The arc-shaped protrusions of the stamping rod 51 roll and abut against the circular groove of the abutting disc 6. The abutting disc 6 will rotate synchronously with the rotation of multiple stamping rods 51. That is, the movement trajectory of the circular groove coincides with the movement trajectory of the end of the stamping rod 51. In this way, static friction is formed between the stamping rod 51 and the abutting disc 6.

[0031] The abutting disc 6, rotating frame 2, rotating seat 72 and mounting seat 71 of the mounting module 7 are all made of wear-resistant material. The circular groove of the abutting disc 6 is coated with a wear-resistant coating, and the bearing where the rotating seat 72 and mounting seat 71 are connected is also coated with a wear-resistant coating.

[0032] refer to Figure 2 A reset assembly 8 is provided between the rotating frame 2 and the stamping rod 51. The reset assembly 8 includes a reset spring 81 and a spring retaining ring 82. Two reset springs 81 and two spring retaining rings 82 are provided. The spring retaining ring 82 is coaxially fixed on the side of the rotating frame 2 near the abutting disc 6. The stamping rod 51 is circumferentially fixed with an annular step 511. The reset spring 81 is sleeved on the stamping rod 51, and one end of the reset spring 81 abuts against the spring retaining ring 82, and the other end abuts against the annular step 511.

[0033] The implementation principle of the die-cutting mechanism of the milk candy machine in this embodiment is as follows: By optimizing the cam abutment structure at both ends of the stamping rod 51, the sliding friction between the stamping rod 51 and the abutment disc 6 is converted into rolling friction and static friction, effectively reducing the wear of the stamping rod 51. The stamping rod 51 moves in a circular motion under the drive of the rotating frame 2. When the stamping action is performed, the stamping rod 51 is brought close to the mold cavity 3 by the action of the abutment disc 6, and stamps the milk candy raw material in the mold cavity 3. After the stamping is completed, the reset assembly... Part 8 returns the stamping rod 51 to its initial position, and the abutting disc 6 rotates synchronously with the circumferential movement of the stamping rod 51. Through the cooperation of the circular groove and the arc-shaped protrusion, good contact and motion coordination between the stamping rod 51 and the abutting disc 6 are ensured. This structure improves the stroke accuracy of the stamping rod 51, making the stamped candies more uniform and standardized. At the same time, the stamping rod 51 is not easy to wear and has a longer service life, reducing the maintenance cost of the equipment and improving the efficiency and quality of milk candy production. Compared with the traditional stamping die mechanism, it has been significantly improved and enhanced.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
