Description

Technical Field

[0001] This utility model relates to the field of food processing machinery, specifically a water-cooled mold head structure for a filling machine, which is particularly suitable for processing products that are sensitive to the temperature of the dough and need to be filled and shaped at low temperatures. Background Technology

[0002] A filling machine is a key piece of equipment in the food industry used to produce filled foods (such as mooncakes, steamed buns, glutinous rice balls, and sandwich pastries). Its working principle is usually to feed the dough and filling into the mold head separately, where the filling is wrapped and the product is initially shaped.

[0003] In existing technologies, during the operation of a filling machine die head, the fabric is subjected to intense mechanical shearing and friction during conveying and extrusion, easily generating a large amount of heat and causing the fabric temperature to rise. For fabrics with high oil content or containing temperature-sensitive ingredients (such as chocolate, cream, or certain colloids), this temperature rise can lead to softening, increased viscosity, and altered flowability, thereby affecting the stability of the filling process, the product's shaping effect, and its appearance quality. In severe cases, it may even cause fabric denaturation, affecting the final product's taste and hygiene safety (e.g., accelerating microbial growth). Currently, conventional filling machine dies lack effective temperature control methods, making it difficult to solve the problems caused by the temperature rise due to extrusion. Utility Model Content

[0004] This invention overcomes the shortcomings of the existing technology and provides a water-cooled die head structure for a stuffing machine. It can effectively cool the fabric channel, suppress the temperature rise of the fabric during the stuffing process, and ensure product quality and operational stability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a water-cooled mold head structure for a stuffing machine, including a large body stuffing tube, the large body stuffing tube being a hollow tubular structure with a stuffing inlet hole on one side of its upper part, multiple guide blocks being arranged on the outer side of the large body stuffing tube, the guide blocks cooperating to form a fabric channel, the guide blocks being an inverted triangular structure with a larger upper part and a smaller lower part, an inner stuffing tube plug being provided at the upper opening end of the large body stuffing tube, and an inner mold being provided at the lower opening end of the large body stuffing tube, the inner mold being funnel-shaped and fixedly fitted onto the large body stuffing tube, a water-cooled mold head shell being fitted on the outer side of the large body stuffing tube between the inner stuffing tube plug and the inner mold, and along the water-cooled mold head shell A circumferentially arranged sandwich-type water-cooling channel is provided, with cooling water inlet and outlet located radially at both ends of the water-cooling channel. The inner sidewall of the water-cooled die head housing is closely fitted with the sidewall of the guide block, forming a direction that restricts the passage of the fabric in cooperation with the guide block. A filling inlet is provided on the water-cooled die head housing at the position corresponding to the filling hole, and a fabric inlet is provided on the other side of the water-cooled die head housing corresponding to the filling inlet. The filling inlet is connected to the filling hole, and the filling enters into the large body filling tube. The fabric inlet enters into the cavity between the large body filling tube and the water-cooled die head housing and moves along the fabric channel. Both the filling inlet and the fabric inlet are located on the upper side of the water-cooling channel to cool the fabric entering the fabric channel and prevent it from heating up due to compression. An outer mold is provided on the lower side of the water-cooled mold head housing. The outer mold is located outside the inner mold, and the two guide and shape the incoming fabric and filling.

[0006] Furthermore, the water-cooling channel is a connected structure surrounding the water-cooling mold head housing, the filling inlet and the fabric inlet are coaxially arranged, and the cooling water inlet and outlet of the water-cooling channel are also coaxially arranged.

[0007] Furthermore, an inner filling tube positioning ring is provided on the outer side of the large body filling tube at the lower end of the water cooling channel. An arc-shaped elongated hole is provided in the area of ​​the inner filling tube positioning ring located in the fabric channel. The arc-shaped elongated hole is used to squeeze the fabric.

[0008] Furthermore, a gear is fitted onto the large body filling tube below the inner filling tube positioning ring. An upper bushing and a lower bushing are respectively provided on the upper and lower sides of the gear. The gear is movably mounted inside the mold head through the upper and lower bushings. Multiple fins are arranged in a ring on the inner side of the gear. These fins are located in the fabric channel between the large body filling tube and the water-cooled mold head housing to stir the passing fabric. The gear meshes with an external power gear through a power connection hole provided in the mold head.

[0009] Furthermore, the two ends of the die head are symmetrically provided with movable quick-connect slots, which can be detachably connected to the filling machine.

[0010] The advantages of this invention compared to existing technologies are as follows: By setting a surrounding jacketed water-cooling channel within the water-cooled die head housing, this application can effectively and uniformly cool the channel area through which the fabric flows, promptly removing heat generated by mechanical shearing and friction, and significantly suppressing fabric temperature rise. This effectively avoids problems such as fabric softening, stickiness, and reduced fluidity due to temperature increases, ensuring the stability of the filling process and the consistency of product forming, making it particularly suitable for temperature-sensitive fabrics. It also improves product hygiene and safety, as low-temperature environments are unfavorable for the rapid reproduction of microorganisms. The structural design is reasonable, with the cooling system isolated from the material system, eliminating the risk of contamination, and it is easy to integrate into existing filling equipment, as well as facilitating disassembly, cleaning, and maintenance. By adding a rotatable finned gear, the flowing fabric can be agitated and squeezed secondary, resulting in a more uniform fabric structure and better cooling effect. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] like Figures 1-4As shown, this utility model discloses a water-cooled die head structure for a stuffing machine, comprising a large filling tube 1, which is a hollow tubular structure with a filling inlet 2 on one side of the upper part. Multiple inverted triangular guide blocks 3, larger at the top and smaller at the bottom, are fixed to the outside, forming a fabric channel between the guide blocks 3. The upper end of the large filling tube 1 is closed by an inner filling tube plug 4, and a funnel-shaped inner mold 5 is installed at the lower end. A water-cooled die head shell 6 is fitted around the large filling tube 1 between the inner filling tube plug 4 and the inner mold 5. This shell has a sandwich-type water-cooling channel 7 designed in the circumferential direction, with cooling water inlets and outlets at both ends. The inner wall of the water-cooled die head shell 6 is tightly fitted to the side walls of the guide blocks 3, jointly constraining the fabric flow path. The shell has a filling inlet 8 communicating with the filling inlet 2, and a fabric inlet 9 located on the other side. Both the filling inlet 8 and the fabric inlet 9 are located upstream of the water-cooling channel 7. An outer mold 10 is installed below the water-cooled mold head housing 6. The outer mold 10 is fitted outside the inner mold 5 and works together with the inner mold 5 to guide the fabric to wrap the filling and form it.

[0018] In this invention, during assembly, the large filling tube 1 serves as the central component, with multiple guide blocks 3 welded or integrally formed on its outer side. The water-cooled mold head housing 6 is precision-machined to ensure that its inner wall fits well with the sides of the guide blocks 3, forming a closed fabric flow channel. Cooling water enters from one inlet of the water-cooling channel 7, flows through the interlayer channel surrounding the housing, and exits from the outlet, continuously carrying away heat.

[0019] During operation, the filling enters the internal cavity of the main filling tube 1 through the filling inlet 8 and the filling inlet hole 2. The fabric enters the annular space between the main filling tube 1 and the water-cooled mold head housing 6 through the fabric inlet 9, and flows downward in the channel formed by the guide block 3. During this process, the flowing fabric comes into full contact with the cooling inner wall of the water-cooled mold head housing 6, and the heat is quickly transferred to the circulating cooling water, thus keeping the fabric at a suitable low temperature. The cooled fabric continues downward and is moderately compressed when passing through the arc-shaped elongated hole 12 on the inner filling tube positioning ring 11. If the equipment is equipped with a gear 13, external power is transmitted through the power connection hole 17, driving the gear 13 to rotate. Its inner fins further agitate and gently shear the fabric, promoting uniform fabric structure and enhancing the cooling effect. Finally, the fabric and filling converge in the forming area formed by the funnel-shaped inner mold 5 and the outer mold 10. The fabric wraps around the filling and is extruded from the lower outlet, forming a pre-shaped filled product. The entire die head is quickly connected and disconnected from the main body of the filling machine through the movable quick-connect slots 18 on both sides of the die head 16, which facilitates maintenance and cleaning.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
