Description

Technical Field

[0001] This utility model relates to the field of ice cream machine technology, and in particular to a dispensing structure for a hard ice cream machine. Background Technology

[0002] As a specialized frozen dessert production equipment, the core function of a hard ice cream machine is to transform mixed ingredients into a solid ice cream with a uniform texture and dense structure through the synergistic effect of dynamic stirring and low-temperature freezing. The main body of the equipment typically includes a refrigeration system, a stirring mechanism, and a stainless steel mixing tank assembly.

[0003] Existing equipment typically employs a bottom-mounted sliding plate switch design for the discharge port, controlling discharge by manually sliding a metal or plastic baffle. However, this traditional structure has significant drawbacks: firstly, the mechanical friction between the sliding plate and the trough is substantial, especially under low-temperature conditions where lubrication performance deteriorates, resulting in insufficient operational smoothness and impacting efficiency in continuous production scenarios; secondly, the sealing between the sliding plate and the discharge port is poor, allowing residual ice cream to easily breed microorganisms in the gaps, posing a food safety hazard. Therefore, further improvements are needed. Utility Model Content

[0027] Example

[0028] Reference Figures 1 to 3 The present invention proposes a discharging structure for a hard ice cream machine, comprising: a machine base 10, a material tank 20, a stirring assembly 30, and a discharging assembly 40;

[0029] The material hopper 20 is installed above the machine base 10, and the mixing component 30 is located inside the material hopper 20; the material hopper 20 is provided with a discharge port 21;

[0030] The discharge assembly 40 includes a discharge pressure plate 41, a discharge sealing ring 42, and an opening / closing wrench 43. The discharge pressure plate 41 is provided with a discharge insertion hole 411, and the discharge sealing ring 42 is embedded in the discharge insertion hole 411. The discharge pressure plate 41 is detachably installed on the machine base 10 and presses the discharge sealing ring 42 against the discharge port 21. The opening / closing wrench 43 is rotatably installed on the machine base 10 or the discharge pressure plate 41 and includes a sealing plate 431 and a wrench arm 432. The opening / closing wrench 43 can be rotated by the wrench arm 432 to move the sealing plate 431 below the discharge insertion hole 411 and press the discharge sealing ring 42 against it.

[0031] In this invention, the synergistic design of lever-type rotary opening and closing with sealing and pressing significantly improves the ease of operation and hygiene safety of the equipment. The rotary drive of the opening and closing lever 43 replaces the traditional linear sliding structure of the slide plate, utilizing the lever principle to greatly reduce operating resistance. This ensures stable opening and closing action, especially in low-temperature environments, reducing the intensity of manual intervention and adapting to the fast-paced demands of continuous production. Through the pressing design of the discharge pressure plate 41 and the discharge sealing ring 42, combined with the secondary pressing of the sealing plate 431 on the embedded hole, a multi-layered dynamic seal is achieved at the discharge port, effectively preventing leakage of residues and the intrusion of external contaminants.

[0032] In this embodiment, a discharge support cover 44 is also embedded in the discharge hole 411; the discharge sealing ring 42 abuts against the discharge support cover 44 and the discharge hole 411. The addition of the discharge support cover 44 serves as a rigid support structure for the sealing ring. Through its cooperation with the discharge hole 411 and the sealing ring, a uniform force support is formed, avoiding the sealing failure caused by long-term pressure deformation of the sealing ring, further extending the service life of the sealing assembly, and enhancing the deformation resistance of the discharge port under high pressure conditions.

[0033] Specifically, the discharge support cover 44 includes an annular support ring 441 and a central connecting rib 442. The composite structure design of the annular support ring 441 and the central connecting rib 442 ensures the overall strength of the discharge support cover 44 while reducing the weight of the component and lowering material costs through the hollow layout of the connecting rib. Furthermore, the contact surface between the annular support ring 441 and the sealing ring forms a continuous annular support, ensuring the uniformity of the sealing pressure distribution and avoiding wear of the sealing ring caused by local stress concentration.

[0034] In this embodiment, the discharge sealing ring 42 includes a central sealing ring 421. The outer and inner edges of the central sealing ring 421 extend axially with a first sealing cylinder 422 and a second sealing cylinder 423 of different diameters. The diameter of the first sealing cylinder 422 is larger than that of the second sealing cylinder 423. The outer surfaces of the first sealing cylinder 422, the central sealing ring 421, and the second sealing cylinder 423 abut against the discharge hole 411, and their inner surfaces abut against the discharge support cover 44. The three-section sealing structure of the first sealing cylinder 422, the second sealing cylinder 423, and the central sealing ring 421, through the axial extension design of different diameters, achieves multi-stage radial sealing with the discharge hole 411 and the discharge support cover 44. Specifically, the large-diameter first sealing cylinder 422 fits against the outer wall of the hole, and the small-diameter second sealing cylinder 423 tightly covers the inner wall of the support cover, forming a bidirectional sealing barrier that effectively blocks the axial or radial penetration of ice cream residue, improving sealing redundancy.

[0035] In this embodiment, the dispensing assembly 40 further includes a dispensing guide hopper 45; the dispensing guide hopper 45 is located below the dispensing insert 411. The addition of the dispensing guide hopper 45 guides the ice cream to fall along a preset path through its conical or arc-shaped inner wall, reducing waste caused by splashing or adhesion during the dispensing process, while also preventing material from accumulating around the dispensing port, reducing cleaning difficulty, and improving dispensing efficiency and hygiene control.

[0036] Furthermore, the discharge assembly 40 also includes a vertical protective cover 46, which is arranged around the sides and rear of the discharge pressure plate 41; the discharge guide hopper 45 is detachably installed below the vertical protective cover 46; and the opening / closing lever 43 is located in front of the discharge pressure plate 41. The three-sided encircling structure of the vertical protective cover 46 forms a physical isolation barrier to prevent external contaminants (such as dust and moisture) from entering the discharge area, while limiting the opening / closing lever 43 to the front operating position, optimizing the human-machine interaction logic. The detachable connection design between the discharge guide hopper 45 and the protective cover further enables modular cleaning and maintenance, avoiding the generation of cleaning dead corners in traditional integrated structures.

[0037] Specifically, a connecting slide rail 461 is provided above the vertical protective cover 46, and a connecting slide groove 412 is provided above the discharge pressure plate 41. The connecting slide rail 461 can be slidably installed in the connecting slide groove 412. The sliding engagement mechanism between the connecting slide rail 461 and the connecting slide groove 412 allows the vertical protective cover 46 to be quickly disassembled and assembled along a preset track without the need for additional tools, greatly reducing maintenance time.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
