Description

Technical Field

[0001] This utility model belongs to the field of ice cream machine ingredient technology, and in particular relates to a raw material tube for ice cream machines. Background Technology

[0002] In the design and use of ice cream machines, the feed pipe plays a crucial role, responsible for transporting ingredients from the feed container to the machine for processing. However, traditional feed pipe designs have some drawbacks, particularly in terms of feed delivery efficiency and hygiene. The original feed pipe had a high discharge port, resulting in significant feed loss during disassembly and cleaning, and a slow discharge speed at lower liquid levels. This not only leads to feed waste but can also affect the quality of the final product due to the potential deterioration of residual ingredients.

[0003] Furthermore, when the raw material returns to the top of the feed tube, it will come into contact with the handle of the feed tube, causing contamination of the raw material. When the ice cream machine is working, the inner tube may be pushed up when the raw material returns, causing it to separate from the outer tube. When the machine is closed, the inner tube cannot close the feed inlet, resulting in waste of raw material. Utility Model Content

[0004] (a) Purpose of the utility model In order to overcome the above shortcomings, the purpose of this utility model is to provide a raw material tube for an ice cream machine to solve the above technical problems.

[0005] (II) Technical Solution To achieve the above objectives, the technical solution provided in this application is as follows: An ice cream machine feed tube, installed in a feed container for connecting to a freezing cylinder, includes an outer tube and an inner tube fitted inside the outer tube. The top of the outer tube has a locking groove, and the top of the inner tube has a locking limiting plate corresponding to the locking groove. The outer tube has a feed inlet located at the lowest point of the feed container. The bottom of the inner tube has a feed notch. The inner tube has a sealing ring that is squeezed between the inner and outer tubes, dividing the gap between them into upper and lower parts. The sealing ring is inclined on the outer wall of the inner tube, with its higher point directly above the feed notch and its lower point opposite the feed notch. When the inner tube is installed inside the outer tube, the height of the feed inlet is higher than the lower point of the sealing ring but lower than the feed notch.

[0006] Preferably, the locking limiting plate is installed on the outer wall of the inner tube, and a radial groove is provided on one side of the top of the outer tube, and fixing plates are provided at both ends of the other side. The arc shape of the fixing plate matches the arc shape of the outer tube, and a recessed groove is formed between the fixing plate and the radial groove.

[0007] Preferably, the raw material tubes are divided into dark and light colors, which are used to match dark ice cream raw materials and light ice cream raw materials, respectively.

[0008] Preferably, the top of the inner tube is provided with two vertical rotating plates, which are symmetrically arranged about the center of the inner tube. One of the rotating plates is provided with a closed mark, and the other rotating plate is provided with an open mark. The outer tube is provided with an indication mark indicating that the position is reached.

[0009] Preferably, the inner diameter of the outer tube includes a control cavity with a gap between it and the outer wall of the inner tube, and a feeding cavity located at the lower end of the control cavity. The control cavity is shaped like a frustum with a larger top and a smaller bottom, and the feeding cavity is shaped like a frustum with a smaller top and a larger bottom. The bottom diameter of the control cavity is larger than the top diameter of the feeding cavity.

[0010] Preferably, the outer tube has multiple annular protrusions, and an annular sealing ring is installed at the lower end of the outer tube.

[0011] Preferably, the feed notch is located at the bottom edge, with a width of a, where a is 0.15-0.35 times the outer diameter of the bottom of the inner tube, and a height of b, where b is 1-1.5 times the outer diameter of the bottom of the inner tube. The edges of the feed notch are rounded.

[0012] Preferably, the feed inlet is square, and the edges of the feed inlet are rounded.

[0013] Beneficial effects: 1. Improve raw material conveying efficiency: By using precisely designed sealing rings, feed notches, and feed inlets, the flow path of raw materials can be optimized, reducing the residue of raw materials in the container and thus improving the efficiency of raw material conveying.

[0014] 2. Ensure connection stability: The combined use of the locking groove and the locking limit plate ensures that the inner tube and the outer tube are stably connected when the raw materials in the freezing cylinder return, avoiding the problem of incomplete connection caused by the inner tube being pushed up.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-4 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0017] This utility model provides a raw material tube for an ice cream machine, used to be installed in a raw material tank 3 and connected to a freezing cylinder 4. The raw material tube includes an outer tube 1 and an inner tube 2 sleeved inside the outer tube 1. The top of the outer tube 1 has a locking groove 12, and the top of the inner tube 2 has a locking limiting plate 22 corresponding to the locking groove 12. The locking limiting plate 22 is installed on the outer wall of the inner tube 2. A radial groove is provided on one side of the top of the outer tube, and fixing plates 11 are provided at both ends of the other side. The fixing plates 11 are arc-shaped to match the arc shape of the outer tube, forming a locking groove 12 between the fixing plates 11 and the radial groove. This not only enhances the connection stability between the inner tube 2 and the outer tube 3, ensuring a reliable connection between the inner and outer tubes when raw materials are returned, but also significantly improves the stability of the raw material tube, reducing the problem of incomplete insertion caused by the inner tube being pushed up. It also prevents the inner tube from rising in the closed state, causing the inlet to be unable to seal and raw materials to flow into the freezing cylinder, resulting in waste. This improves the reliability of raw material delivery and the production efficiency of the ice cream machine.

[0018] The outer wall at the top of the outer tube is provided with a pull handle plate, which is evenly distributed in a ring shape and at least two are provided, so as to facilitate the pulling up of the raw material tube.

[0019] The outer tube 1 is provided with a feed inlet 15, which is located at the lowest point of the raw material tank 3 to ensure that the raw material can flow smoothly into the inner tube and reduce the residue in the raw material tank 3. The feed inlet is square and the edges of the feed inlet are rounded for easy cleaning. At the same time, the shape of the feed inlet is set so that the diameter of the feed inlet remains basically unchanged when the liquid level changes.

[0020] The inner tube 2 has a feed notch 24 at its bottom and a sealing ring 23 on its surface. This sealing ring 23 is compressed between the inner tube 2 and the outer tube 1, sealing the gap between them in two parts. The sealing ring 23 is inclined on the outer wall of the inner tube 2, with its higher point directly above the feed notch 24 and its lower point opposite the feed notch 24. When the inner tube 2 is installed inside the outer tube 1, the height of the feed inlet 14 is higher than the lower point of the sealing ring 23 and corresponds to the feed notch 24. In use, the raw material flow in the raw material tank 3 is controlled by adjusting whether the inlet 15 corresponds to the inlet notch 24 or to the upper end of the sealing ring 23 on the opposite side of the inlet notch 24. When it corresponds to the inlet notch 24, the raw material in the raw material tank 3 flows into the inlet chamber 17 of the outer tube through the inlet 15, and then into the freezing cylinder 4. When it corresponds to the sealing ring 23 on the opposite side, the height of the sealing ring 23 on the opposite side of the inlet notch 24 is lower than the inlet notch, and the raw material is blocked at the upper end of the sealing ring 23 by the sealing effect of the sealing ring 23, thus preventing it from entering the freezing cylinder 4 and closing the raw material tube. The operation is simple and convenient, and the simple structure can effectively control the flow of raw materials.

[0021] Preferably, the raw material tubes are divided into dark and light colors, used to match dark-colored ice cream ingredients and light-colored ice cream ingredients, respectively. For example... Figure 4 As shown, because the raw material tube is quite high and the raw material container is located at the top of the ice cream machine, after opening the lid of the raw material container, the color of the raw material tube can be used to identify which type of ice cream raw material it is. There is no need to use tools to climb up and see the raw material inside the container, which makes it easy for customers to identify directly when using the machine. At the same time, dark-colored raw materials use dark-colored raw material tubes to avoid staining light-colored raw material tubes.

[0022] The inner tube 2 has two vertical rotating plates 21 at its top. These plates are symmetrically arranged about the center of the inner tube 2 and do not affect the upper opening of the inner tube. One rotating plate has an opening mark, located directly above the feed notch (e.g., circular), while the other rotating plate has an opening mark, e.g., rectangular. The outer tube has an indication mark indicating the position. When the opening mark is rotated to the indication mark, the feed notch aligns with the feed inlet. When the closing mark is rotated to the indication mark, the feed inlet aligns with the upper part of the lower sealing ring.

[0023] The operator can adjust the position of the inner tube 2 using the rotating plate 21 as needed to ensure accurate connection between the raw material tube and the freezing cylinder 4, thereby improving the raw material conveying efficiency. Furthermore, compared to traditional round rotary handles, the rotating plate 21 allows for a smoother, non-slip rotation, improving the user experience. Simultaneously, the vertical arrangement of the rotating plates forms a guide; when raw materials return from the inside of the inner tube, they flow down between the two rotating plates, and in most cases, they do not flow to the outside of the rotating plates, i.e., the area where the operator's hand is, thus preventing contamination of the raw materials and ensuring food safety.

[0024] The inner diameter of the outer tube 1 includes a control cavity 17 with a gap between it and the outer wall of the inner tube 2, and a feeding cavity 18 located at the lower end of the control cavity 17. The control cavity 17 is a frustum shape with a larger top and a smaller bottom, and the feeding cavity 18 is a frustum shape with a smaller top and a larger bottom. The bottom diameter of the control cavity 17 is larger than the top diameter of the feeding cavity, which supports the inner tube 2, helps control the flow of raw materials, reduces the retention of raw materials in the tube, and thus improves the conveying efficiency of raw materials and the production efficiency of the ice cream machine.

[0025] The outer tube is provided with multiple annular protrusions 14 to indicate the effective capacity in the raw material barrel, so that the user can control the amount of raw material in the raw material barrel. The lower end of the outer tube 1 is provided with an annular sealing ring 16, which realizes the sealing setting between the raw material tube and the conveying tube, and prevents the raw material from being directly sent to the freezing cylinder from the conveying tube.

[0026] The feed notch 24 is located at the bottom edge of the inner tube 2, with a width of a, which is 0.15-0.35 times the outer diameter of the bottom of the inner tube 2, and a height of b, which is 1-1.5 times the outer diameter of the bottom of the inner tube 2. The rounded edges of the feed notch 24 help reduce the residue of raw materials at the bottom of the tube and improve the utilization rate of raw materials.

[0027] In use, the ingredient tube for this ice cream machine is first inserted into the outer tube. By rotating the rotating plate on the inner tube, the feeding notch is aligned with the feeding port of the outer tube to open the ingredient channel. Alternatively, the end without the feeding notch can be rotated so that all feeding notches are located above the sealing ring, achieving a closed state. When the feeding notch is aligned with the feeding port, the ingredients flow from the ingredient container through the feeding port into the feeding notch, then into the feeding chamber of the outer tube, and finally into the freezing cylinder. When the ingredient channel is closed, the ingredients are blocked at the top of the sealing ring and cannot enter the freezing cylinder. Furthermore, the type of ice cream ingredient can be identified by the color of the ingredient tube without opening the ingredient container, making it convenient and quick. The annular protrusion on the outer tube indicates the effective capacity of the ingredient container, allowing users to easily understand the remaining amount of ingredients.

[0028] This invention enhances the connection stability between the inner and outer tubes through the cooperation of the locking limiting plate and the locking groove, reducing the problem of incomplete insertion caused by the inner tube being pushed up, and ensuring the reliability of raw material transportation. The rotating plate is simple and convenient to operate. Its vertical arrangement forms a guide; when raw material returns from inside the inner tube, it flows down between the two rotating plates, generally preventing contamination of the outside of the rotating plates and ensuring the hygiene of the raw material. The rounded edges of the feed inlet and feed notch help reduce raw material residue in the raw material container and at the bottom of the tube, improving the utilization rate of the raw material.
