Description

Technical Field

[0001] This utility model relates to the field of food processing machinery, and in particular to a molding device for producing chocolate pellets. Background Technology

[0002] In chocolate product manufacturing, the molding efficiency and quality of small granulated chocolates are key industry concerns. In some existing molding equipment, molten chocolate material is injected into the mold cavity. If air within the cavity is not adequately expelled during this process, air bubbles or material shortages can easily form inside or on the surface of the product, affecting its integrity and appearance. Some equipment attempts to vent air through the gaps between mating parts, but this method may face issues such as ineffective venting or the risk of material leakage. Furthermore, the ejection mechanisms of some equipment may have room for improvement in terms of neutrality or synchronization when ejecting the molded granules, potentially affecting the surface quality or morphological integrity of the granules. For molds with multi-cavity array layouts, how to distribute the material more evenly among the cavities to improve the consistency of weight and density among the granules is also a practical consideration. Therefore, seeking a solution that balances effective venting, smooth demolding, and balanced filling to improve product shape consistency and production stability is of significant importance. Utility Model Content

[0003] In view of this, the present invention provides a chocolate pellet forming equipment, which aims to achieve efficient and high-quality automated production of chocolate pellets through the coordinated cooperation of a precision channel system inside the template and an external driving component.

[0004] The objective of this utility model is achieved through the following technical solution: A chocolate pellet forming device includes a base, a column fixed to the base, a forming mold mounted on the column, a drive cylinder fixed to the column or the base, and multiple push rods driven by the drive cylinder and facing the mold. The forming mold includes a material cylinder and a template connected to the bottom of the material cylinder. The template has multiple vertically penetrating forming holes, multiple blind storage holes, and guide holes connecting the forming holes and the storage holes. The forming holes and storage holes are arranged in an array at intervals in a horizontal plane. The push rods correspond to the forming holes. At least one guide hole located on the outermost side of the array penetrates the side wall of the template to connect to an exhaust device.

[0005] This solution achieves efficient and high-quality molding of chocolate granules through integrated design. The core is the coordinated operation of a precision hole system within the mold, consisting of molding holes, storage holes, and guide holes, along with the ejector rod and drive cylinder. The material cylinder holds the raw material, which, under gravity and subsequent pressure, flows through the guide holes into the molding holes. The drive cylinder drives the ejector rod to compact the material within the molding holes, molding it and ejecting the granules. The array layout increases the output per batch. A key innovation is extending the edge guide holes to the mold sidewalls to connect to an venting device, effectively expelling air from the mold during filling, preventing product defects and surface flaws caused by air bubbles, and significantly improving yield and quality. The overall structure is robust and compact, operates smoothly, and enables continuous automated production.

[0006] Furthermore, the guide holes are distributed radially or in a grid pattern in the horizontal plane, forming a raw material distribution network inside the mold. The guide hole located on the outermost side of the array serves as the main exhaust channel, and its connection with the sidewall of the mold plate is provided with an embedded mounting interface for fixing the exhaust device. The end shape of the ejector rod is adapted to the bottom shape of the forming hole and can extend to the upper part of the die nozzle to ensure that the ejection force acts directly on the particle body, achieving smooth demolding. The drive cylinder drives all the ejector rods simultaneously through a linkage plate, ensuring absolute synchronization of their movements.

[0007] Preferably, the exhaust device is a one-way valve that only allows gas to be discharged.

[0008] A one-way valve enables the directional discharge of gas inside the mold and prevents external contamination. During filling, the pressurized air inside forces the valve open and is discharged; when the pressure is released, the valve closes, effectively preventing raw material leakage and the entry of external impurities, ensuring product hygiene. This process is completed automatically, improving equipment reliability and automation levels.

[0009] Preferably, the central axes of the guide holes in the same column or row are at the same horizontal height.

[0010] This design ensures uniform material flow within the same column or row. When the ejector pin applies pressure, the flow resistance and distance of all guide holes along this path are essentially the same, allowing multiple cavities to be filled synchronously, at equal pressure, and at equal speed. This directly results in consistency in the weight, density, and internal structure of the formed chocolate granules, significantly improving product quality stability.

[0011] Preferably, the barrel and the template are integrally formed.

[0012] The seamless, one-piece structure completely eliminates material residue and cleaning dead zones at the joints, facilitating cleaning and preventing cross-contamination. Simultaneously, the structure boasts high mechanical strength and excellent integrity, effectively resisting cyclical pressure and reducing deformation. This ensures precise and stable molding dimensions during long-term use, extending mold life.

[0013] Preferably, the barrel and the template are detachable separate connection structures.

[0014] The modular connection offers high flexibility and convenience. When product specifications need to be changed, only the template needs to be replaced, reducing conversion costs and time. At the same time, it facilitates individual deep cleaning, maintenance, or replacement of the barrel or template, avoiding the scrapping of the entire mold due to local damage and reducing long-term equipment operation and maintenance costs.

[0015] Preferably, a die nozzle is detachably connected to the bottom of the forming hole, and there is a gap between the lower end face of the die nozzle and the upper surface of the machine base.

[0016] The detachable die nozzle allows for easy replacement to produce chocolate pellets with different end shapes, enhancing the equipment's versatility. The gap between the die nozzle and the machine base provides a smooth ejection channel for the formed pellets, preventing squeezing or scratching during ejection and ensuring the integrity of the product's shape and a smooth surface.

[0017] Preferably, the diameter of the guide hole is smaller than the diameter of the forming hole and the storage hole.

[0018] The smaller diameter of the guide orifice creates a throttling effect, increasing the resistance to material flow. This helps to make the filling process smoother and, to some extent, hinders the backflow of material from the forming orifice to the storage orifice when the ejector pin pressure is interrupted. This helps to maintain the shape of the formed particles, prevents root stringing or deformation, and improves forming reliability.

[0019] Preferably, the cross-sectional shape of the forming hole is circular, elliptical, or polygonal.

[0020] By changing the cross-sectional shape of the forming orifice, chocolate granules with different external shapes can be produced directly, such as columnar, spherical, ellipsoidal, or polygonal granules with angular edges. This design flexibility allows the equipment to quickly adapt to diverse product design needs, enhancing its market competitiveness.

[0021] Preferably, the drive cylinder is a pneumatic cylinder, which is fixed to the column by a bracket.

[0022] The cylinder has the advantages of rapid action, fast response, and easy maintenance. It is securely mounted to the column using a bracket, forming a rigid support and force transmission path, effectively reducing vibration, ensuring the precision and synchronization of the push rod's movement, and providing stable and reliable power for the molding process.

[0023] Preferably, the template is made of food-grade metal or engineering plastic.

[0024] Both food-grade metals and engineering plastics meet food safety standards, ensuring no harmful reactions with chocolate raw materials. These materials possess excellent surface properties, sufficient mechanical strength and durability, are easy to clean, and can withstand the periodic compression of ejector pins, guaranteeing product safety and the long service life of the mold.

[0025] The advantages of this utility model compared to the prior art are: This novel chocolate pellet forming equipment achieves continuous pellet forming through a unique internal channel system within the mold and the coordination of an external actuator. The specific layout of the forming holes, storage holes, and guide holes facilitates the distribution and flow of raw materials. A drive cylinder synchronously moves the ejector rod, compacting and ejecting the raw materials already filled into the forming holes; this array-like distribution helps improve the efficiency of a single forming operation. Crucially, the guide holes located at the edge of the array extend to the sidewall of the mold and connect to the venting device. This structure provides a dedicated escape channel for air within the mold cavity. During the material filling process, internal air can be expelled through this channel, helping to reduce defects such as product bubbles and uneven filling caused by gas retention, thus positively impacting product appearance quality and molding yield. The entire device has a reasonable structural layout and operates smoothly. Attached Figure Description

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0037] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0038] This embodiment provides a chocolate pellet forming device, including a base 1, and further including... The column 2 is fixed to the base 1; The forming mold 3 is set on the column 2 and includes a material cylinder 31 and a template 32 connected to the bottom of the material cylinder 31; Drive cylinder 4, which is fixed on column 2 or base 1; Multiple push rods 5 are driven by a drive cylinder 4 and face the template 32. The template 32 is provided with multiple vertically penetrating forming holes 321, multiple blind storage holes 322, and guide holes 323 connecting the forming holes 321 and the storage holes 322. The forming holes 321 and the storage holes 322 are arranged in an array at intervals in the horizontal plane. The push rods 5 correspond to the forming holes 321. At least one guide hole 323 located on the outermost side of the array penetrates the side wall of the template 32 to connect to the exhaust device.

[0039] This solution achieves efficient and high-quality molding of chocolate granules through an integrated structural design. The core lies in the synergistic effect of the ingenious internal channel system of the template 32 and the external actuator. Molten chocolate material is contained in the cylinder 31, and under gravity and subsequent pressure, the material first fills the storage hole 322. The drive cylinder 4 provides stable and concentrated power, driving multiple push rods 5 to move synchronously. The push rods 5 precisely align and extend into the molding hole 321, compacting the material already inside. This design allows for precise control of the material filling and molding process, ensuring the consistency of weight and shape of each chocolate granule. The array layout of the alternating molding holes 321 and storage holes 322 allows for the arrangement of a large number of molding units within the limited area of ​​the template 32, significantly increasing the output per production cycle and meeting the high efficiency requirements of industrial production. In particular, extending the guide hole 323 located on the outermost side of the array to the side wall of the template 32 and connecting it to the exhaust device constitutes a key innovation. During the raw material filling process, air inside the mold cavity can be effectively discharged to the outside through this channel, avoiding problems such as product defects or surface flaws caused by air bubbles due to air retention, thus fundamentally improving the molding quality and yield rate of the product. The entire device has a compact structure, with the base 1 and column 2 providing stable support, ensuring precise operation and smooth running, and realizing continuous, stable, and automated production from raw materials to finished products.

[0040] In this embodiment, the exhaust device is a one-way valve that only allows gas to be discharged.

[0041] The use of a one-way valve as the venting device enables the directional discharge of gas inside the mold while effectively preventing backflow of external contaminants. When the ejector pin 5 pushes the raw material to fill the cavity, the internal air is compressed. When the air pressure exceeds the opening pressure of the one-way valve, the valve automatically opens, allowing the gas to flow smoothly. When the extrusion stops or the external air pressure is high, the valve closes tightly under the pressure difference or its own elasticity. This not only prevents unsolidified raw material from leaking through the vent and causing waste and contamination, but also isolates dust, microorganisms, and other impurities from the external air from entering the clean molding cavity, ensuring the food hygiene and safety of the chocolate. This design allows the venting process to be completed automatically without additional control, improving the reliability and automation of the equipment.

[0042] In this embodiment, the central axes of the guide holes 323 in the same column or row are at the same horizontal height.

[0043] Setting the guide holes 323 in the same column or row at the same horizontal height ensures the uniformity and consistency of the material flow during filling. When the push rod 5 applies pressure, the path resistance and flow distance of the material flowing from the storage hole 322 through the guide holes 323 to the forming hole 321 are essentially the same for all forming units in that row or column. This symmetrical and balanced flow channel design helps avoid uneven filling speed or pressure loss caused by differences in flow paths, thus allowing multiple cavities to be filled simultaneously, in equal quantities, and at equal speeds. This directly results in a high degree of consistency in the weight, density, and internal structure of the formed chocolate granules, effectively reducing individual differences between products and playing a key role in ensuring the quality stability and standardization of batch products.

[0044] In this embodiment, the material cylinder 31 and the template 32 are integrally formed.

[0045] The material cylinder 31 and the template 32 are manufactured as a single piece, eliminating the assembly gaps and connection seams that may exist in traditional separate connections. This seamless structure fundamentally eliminates the possibility of raw material residue and accumulation at the connection point, greatly facilitating cleaning and rinsing after production and effectively preventing cross-contamination between different batches or flavors of chocolate. In addition, the one-piece structure has higher overall mechanical strength and structural stability. When subjected to the periodic pressure of the drive cylinder 4, it can effectively reduce micro-deformation and stress concentration at the connection point, thereby extending the service life of the mold and further ensuring the long-term accuracy and stability of the molding dimensions.

[0046] In this embodiment, the material cylinder 31 and the template 32 are detachable and separate connection structures.

[0047] The material cylinder 31 and template 32 are connected in a detachable, separate manner, giving the equipment greater flexibility and maintainability. When it is necessary to change product specifications, i.e., change the shape or size of the chocolate granules, only the corresponding template 32 module needs to be replaced, without replacing the entire material cylinder 31 and upper structure. This significantly reduces the cost and time of equipment conversion and improves the adaptability of the production line. At the same time, this design makes deep cleaning, maintenance, or replacement of individual damaged parts of the material cylinder 31 or template 32 much more convenient. Once a component is worn or blocked, it can be removed and repaired or replaced individually, avoiding the scrapping of the entire mold assembly due to a local problem and effectively reducing the long-term operation and maintenance costs of the equipment.

[0048] In this embodiment, a die nozzle 7 is detachably connected to the bottom of the forming hole 321, and there is a gap between the lower end face of the die nozzle 7 and the upper surface of the machine base 1.

[0049] A detachable die nozzle 7 is connected to the bottom of the forming hole 321. Through the gap design between the die nozzle and the machine base 1, the demolding process is optimized and its functionality expanded. As the final product shaping component, the exit shape of the die nozzle 7 directly determines the end shape of the chocolate pellets. The detachable connection allows users to quickly replace the die nozzle 7 with different exit shapes or sizes according to product requirements, thus producing various styles of chocolate pellets on the same machine, greatly enhancing the equipment's versatility. The gap between the lower end face of the die nozzle 7 and the surface of the machine base 1 provides a smooth and unobstructed space for the formed chocolate pellets to fall, ensuring that the pellets fall naturally by gravity after being ejected by the ejector pin 5, avoiding squeezing, sticking, or scratching against the machine surface, and ensuring the integrity of the product shape and a smooth surface. The exit section of the die nozzle 7 has a tapered surface or a rounded chamfer, and its lower outer edge has a polished surface or anti-stick coating to prevent adhesion to the formed pellets.

[0050] In this embodiment, the diameter of the guide hole 323 is smaller than the diameter of the forming hole 321 and the storage hole 322.

[0051] Designing the diameter of the guide hole 323 to be smaller than that of the forming hole 321 and the storage hole 322 at its two ends creates a throttling effect. The smaller diameter increases the resistance to the flow of raw materials. This resistance can effectively buffer and control the filling process, making the filling speed more stable and helping to remove small air bubbles entrained in the raw materials, resulting in a denser filling. More importantly, at the moment when the push rod 5 retracts or stops pressurizing, this throttling structure can, to a certain extent, prevent the reverse flow of raw materials from the forming hole 321 to the storage hole 322 due to surface tension or springback effect. This helps to maintain the stability of the shape of the raw materials in the forming hole 321, prevents stringing or deformation at the root of the particles, and ensures the reliability of the molding quality.

[0052] In this embodiment, the cross-sectional shape of the forming hole 321 is circular, elliptical, or polygonal.

[0053] By designing the cross-sectional shape of the forming hole 321 to be circular, elliptical, or polygonal, a wide variety of external shapes can be directly imparted to the produced chocolate granules. A circular cross-section can produce classic columnar or spherical granules; an elliptical cross-section can produce ellipsoidal or olive-shaped granules; while a polygonal cross-section can produce more aesthetically pleasing granule products with specific angles. This flexible mold design allows manufacturers to quickly respond to market demands and develop a diverse range of product lines without changing core equipment, simply by selecting or replacing templates 32 with different forming hole 321 cross-sections, thus enhancing the product's market competitiveness and appeal.

[0054] In this embodiment, the drive cylinder 4 is a pneumatic cylinder, which is fixed to the column 2 by a bracket 6.

[0055] Using a cylinder as the drive cylinder 4 and fixing it to the column 2 via a bracket 6 provides a solution with efficient power transmission and stable structural support. As a mature and reliable pneumatic component, the cylinder has advantages such as rapid action, fast response, easy maintenance, and relatively low cost, meeting the high-frequency and rapid response requirements of the reciprocating motion of the ejector rod 5 in the chocolate pellet molding process. The bracket 6 securely mounts the cylinder to the column 2, making the drive source installation position more stable and effectively reducing the impact of the cylinder's own vibration on molding accuracy. Simultaneously, it directly transmits the force to the molding die 3 connected to the column 2, forming a rigid force flow path, ensuring the precision and synchronization of the ejector rod 5's movement, thereby guaranteeing the stability and reliability of the molding process.

[0056] In this embodiment, the template 32 is made of food-grade metal or engineering plastic.

[0057] The primary consideration in selecting food-grade metals or engineering plastics to manufacture mold 32 is meeting food safety requirements and ensuring good compatibility with chocolate raw materials. Food-grade metal materials, such as certain types of stainless steel, possess characteristics such as high surface smoothness, high hardness, wear resistance, and corrosion resistance. They are easy to clean and disinfect and can maintain stable dimensional accuracy over a long period. Food-grade engineering plastics may possess self-lubricating and anti-adhesion properties, which facilitate the demolding of chocolate granules. The selection of both materials ensures that no harmful substances migrate into the chocolate product during the production process, guaranteeing the food safety of the final product. At the same time, these materials also possess sufficient mechanical strength to withstand the periodic extrusion of the ejector pin 5, ensuring the durability of the mold under long-term use.

[0058] In actual operation, the chocolate pellet forming equipment operates as a continuous automated cycle. One working cycle of the forming machine is as follows: First, molten chocolate raw material is injected into the feed cylinder 31. Under the action of gravity, the raw material sequentially fills the storage hole 322 and flows into the forming hole 321 through the horizontal guide hole 323. Subsequently, the drive cylinder 4 is activated, pushing all the ejector rods 5 downwards synchronously. The ejector rods 5 enter the forming hole 321 and apply pressure to the raw material, compacting it and completely filling the cavity, thus completing the shaping. During this compaction process, residual air in the mold cavity is squeezed by the raw material and discharged through the venting device located on the side wall of the mold plate 32. After a short period of pressure holding, the drive cylinder 4 drives the ejector rods 5 to continue downwards, completely ejecting the formed chocolate pellets from the forming hole 321 or the die nozzle 7, allowing them to fall off under the action of gravity, completing one production cycle. This cyclical design is suitable for continuous batch production environments.

[0059] It should be further explained that the storage hole 322 not only serves as a temporary storage chamber, but its function as a pressure buffer and compensation chamber is particularly crucial. During the compaction stage of the ejector rod 5, the raw material in the storage hole 322 is replenished to the forming hole 321 under pressure through the guide hole 323 to compensate for the volume change caused by the cooling and shrinkage of the raw material, ensuring that the particles are dense and defect-free. The "throttling effect" of the guide hole 323 is also reflected in this process: its small diameter makes the replenishment flow of raw material smooth and controllable, avoiding air entrainment due to excessive flow rate or impact deformation of the initially formed particles. The entire filling, compaction, pressure holding and demolding process can be precisely controlled by the PLC system to control the pressure, speed and stroke of the drive cylinder 4, so as to adapt to chocolate raw materials with different viscosities and formulations, thereby realizing digital management and optimization of process parameters.

[0060] Another consideration for this equipment is its adaptability to different raw material properties. For chocolate raw materials with varying viscosities or containing different particulate additives, the force and speed of the filling process can be optimized to a certain extent by adjusting the pressure of the drive cylinder 4 and the movement speed of the push rod 5, in order to obtain better molding results.

[0061] Furthermore, ease of maintenance has been taken into consideration. When cleaning or replacement of parts is required, for example, the separately connected barrel 31 and template 32 can be easily separated for individual processing. The detachable nozzle 7 design also simplifies cleaning blockages or changing styles. This design philosophy aims to reduce the difficulty and time cost of long-term equipment maintenance.

[0062] In summary, the chocolate pellet forming equipment provided in this embodiment not only focuses on improving the quality and efficiency of a single forming operation, but also takes into account the equipment's flexibility of use, ease of operation, and long-term maintenance, aiming to meet the requirements of reliability, adaptability, and economy in modern food processing production.

[0063] In another embodiment of this utility model, the venting device is not limited to a mechanical one-way valve, but can also be a microporous breathable metal or an oleophobic breathable membrane. This material allows gas to pass through but effectively blocks the penetration of liquid chocolate, thus achieving the same venting function. Furthermore, the drive cylinder 4 is not limited to a pneumatic cylinder, but can be replaced with a hydraulic cylinder or an electric servo cylinder to provide more precise pressure and position control. The template 32 can, as needed, have a heating element and a temperature sensor (not shown) embedded inside to precisely control the temperature of the mold, preventing premature solidification of the raw material during filling and further improving molding quality. All these alternative solutions fall within the protection scope of this utility model.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
