Description

Technical Field

[0001] This utility model relates to a feeding device for extruding and forming steamed buns. Background Technology

[0002] As a traditional staple food, the feeding and transfer processes after extrusion molding in the industrial production of steamed buns directly affect production efficiency, product quality, and production costs. Currently, the feeding and molding equipment on steamed bun production lines in the market generally suffers from the following problems:

[0003] The opening and closing of the mold needs to be controlled by a cylinder. After the mold is in position, the cylinder moves to actively open the mold. This process is relatively expensive, and the cylinder is noisy and prone to leaking air, which can contaminate the steamed buns.

[0004] Based on the aforementioned pain points in the steamed bun production equipment industry, there is an urgent need for a feeding device for steamed bun extrusion molding that has a reasonable structural design, stable and efficient operation, low cost, and high space utilization. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a feeding device for extruding and forming steamed buns that has a reasonable structural design, stable and efficient operation, low cost, and high space utilization.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A feeding device for extruding and forming steamed buns includes a base plate, a guide plate provided at the top edge of the base plate, the guide plate including an annular portion and a V-shaped portion, a discharge port provided at the position corresponding to the V-shaped portion of the base plate, the discharge port corresponding to the conveyor belt of the production line; a turntable provided on the upper part of the base plate, a spindle provided at the bottom axis of the turntable, the spindle and the base plate being fitted with a bearing; multiple brackets installed at the bottom of the base plate, servo motors fixed by the brackets, the servo motors being programmed by the production line controller, the servo motors and the spindle being fitted with a transmission unit; multiple openable and closable mold structures are provided in an annular shape at the top of the turntable, the openable and closable molds being in a closed state when engaged with the annular portion, and in an open state when engaged with the V-shaped portion, so that the extruded steamed buns fall from the discharge port onto the conveyor belt.

[0008] Preferably, the transmission unit is a spur gear transmission unit or a bevel gear transmission unit.

[0009] Preferably, the openable mold structure includes a fixed module and a movable module. The fixed module and the movable module are combined to form a cavity for forming a shaped dome. The fixed module is fixed to the outer circular surface of the turntable. A mounting plate is provided on the top of the turntable, and two guide rods are installed through the mounting plate. The height of the guide rods is higher than the height of the guide plate. A side plate is provided on the outer wall of the movable module. The guide rods pass through the side plate and are fitted with limit nuts. A spring is sleeved on the guide rods, and the spring acts between the mounting plate and the side plate.

[0010] Preferably, a vertical shaft is provided at the bottom of the active module near the outer side, and a guide wheel is rotatably mounted on the vertical shaft via a bearing, the guide wheel cooperating with the guide plate.

[0011] Preferably, a spherical groove is provided at the bottom of the vertical shaft, through which a rolling ball is inserted. The rolling ball rotates along the spherical groove and acts on the top of the base plate.

[0012] The beneficial effects of this utility model are:

[0013] Precise mold opening and closing control improves molding quality and production continuity: The device employs a design that combines a guide plate with an openable mold structure. The annular and V-shaped sections of the guide plate form a continuous guiding trajectory, which, together with the guide wheels on the movable module, enables sliding guidance. This allows the openable mold structure to precisely complete the "closing-receiving dough-extrusion molding-opening and unloading" cycle during turntable operation. The inner corner arc transition design of the V-shaped section avoids mechanical jamming during mold opening and closing, while the elastic rebound of the spring ensures rapid and thorough mold opening, effectively preventing the formed dough from getting stuck. The annular section ensures good sealing when the mold closes, preventing leakage during dough extrusion. Compared to traditional cam-driven structures, this design significantly improves the stability and precision of mold movements, reduces manual intervention, and ensures production continuity.

[0014] Optimized spatial layout reduces energy consumption and maintenance costs: The transmission unit adopts a bevel gear drive design, allowing the servo motor to be installed horizontally. Compared to the traditional vertical spur gear drive structure, this significantly reduces the overall height of the equipment and improves workshop space utilization. At the same time, the bevel gear drive has higher transmission efficiency, reducing motor power loss and lowering production energy consumption. The horizontally mounted servo motor and simple transmission structure also facilitate equipment installation, inspection, and daily maintenance, shortening maintenance time and reducing maintenance costs.

[0015] To improve operational stability and extend equipment lifespan: The bottom of the movable module features ball bearings mounted on a vertical shaft. These balls roll against the top of the base plate, effectively distributing the pressure on the guide rods during pneumatic pressing, preventing deformation or wear due to concentrated stress. The rolling contact between the guide wheels and guide plates replaces the traditional sliding contact, significantly reducing turntable rotation resistance and mechanical wear. These structural designs collectively enhance equipment operational stability, extend the lifespan of key components such as guide rods and bearings, and reduce equipment failure rates and replacement costs.

[0016] The process is highly efficient and adaptable to the needs of industrial production: the servo motors are programmed and controlled by the production line controller, enabling precise intermittent starts. This ensures that the turntable's operating rhythm is highly matched with processes such as dough conveying, extrusion molding, and conveyor belt transfer, guaranteeing that each openable mold structure can accurately receive the dough, complete the molding, and unload it in a timely manner. This automated and precise control not only improves production efficiency but also ensures the consistency of the molding quality of each steamed bun, meeting the needs of large-scale industrial production.

[0023] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0024] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0025] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] See Figure 1 , Figure 2 and Figure 3The feeding device for extruding and forming steamed buns shown includes a base plate 1. A guide plate 2 is provided at the top edge of the base plate 1. The guide plate 2 includes an annular portion 21 and a V-shaped portion 22. The inner corner of the V-shaped portion 22 is arc-shaped. A discharge port 11 is provided on the base plate 1 corresponding to the position of the V-shaped portion 22, and the discharge port 11 corresponds to the conveyor belt of the production line. A turntable 3 is provided on the upper part of the base plate 1. A spindle tube 31 is provided at the bottom axis of the turntable 3. A bearing (a deep groove ball bearing) is fitted between the spindle tube 31 and the base plate 1. Multiple brackets 4 are installed at the bottom of the base plate 1, and servo motors 5 are fixed on the brackets 4. The servo motors 5 are controlled by the production line controller to achieve intermittent start. A transmission unit 51 is connected between the servo motors 5 and the shaft tube 31. Multiple openable mold structures 6 are arranged in a ring on the top of the turntable 3. When the openable mold 6 is engaged with the ring part 21, it is in a closed state. When the openable mold structure 6 is engaged with the V-shaped part 22, it is in an open state, so that the extruded and formed steamed buns fall from the discharge port 11 onto the conveyor belt.

[0029] In the above technical solution, the servo motor 5 drives the turntable 3 to operate intermittently. During intermittent operation, the dough input from the conveying equipment is received by the openable mold structure 6. Then, the intermittent operation continues until the openable mold structure 6 corresponds to the pneumatic dough pressing equipment. The pneumatic dough pressing equipment presses down to form the dough in the openable mold structure 6. Then, the servo motor 5 continues to drive the turntable 3 to operate intermittently until the openable mold structure 6 is located at the V-shaped part 22. At this time, the openable mold structure 6 opens under the action of elastic rebound, so that the formed steamed buns fall onto the conveyor belt through the feeding port 11.

[0030] The transmission unit 51 is a bevel gear transmission unit.

[0031] The use of bevel gear transmission unit allows for the horizontal mounting of the servo motor, enabling a planar layout and reducing equipment height.

[0032] See Figure 4 As shown, the openable mold structure 6 includes a fixed module 61 and a movable module 62. The fixed module 61 and the movable module 62 are combined to form a cavity 63 for forming a shaped dome. The fixed module 61 is fixed to the outer circular surface of the turntable 3. A mounting plate 331 is provided on the top of the turntable 3. Two guide rods 332 are installed through the mounting plate 331. The height of the guide rods 332 is higher than the height of the guide plate 2. A side plate 64 is provided on the outer wall of the movable module 62. The guide rods 332 pass through the side plate 64 and are fitted with limit nuts 333. A spring 334 is sleeved on the guide rods 332. The spring 334 acts between the mounting plate 331 and the side plate 64.

[0033] In the above technical solution, the closure of the fixed module 61 and the movable module 62 is achieved through the annular portion 21 of the guide plate 2.

[0034] When the turntable 3 moves to the position of the movable module 62 at the V-shaped part 22, the movable module 62 is pushed open by the elastic force of the spring 334, so that the cavity 63 splits in the middle, allowing the already formed bun inside the cavity 63 to fall downwards.

[0035] As the turntable 3 continues to rotate, the movable module 62 returns to its original position under the action of the annular part 21, so that the cavity 63 is formed and the bottom is closed.

[0036] See Figure 5 As shown, a vertical shaft 621 is provided at the bottom of the active module 62 near the outer side. A guide wheel 622 is rotatably mounted on the vertical shaft 621 via a bearing. The guide wheel 622 cooperates with the guide plate 2.

[0037] By contacting the guide wheel 622 with the guide plate 2, the rotational resistance of the turntable 3 can be reduced.

[0038] See Figure 5 As shown, a spherical groove (not shown) is provided at the bottom of the vertical shaft 621. A ball 623 is inserted through the spherical groove and rotates along the spherical groove. The ball acts on the top of the base plate.

[0039] The ball bearing 623 provides greater stability to the cavity 63 when it is subjected to the downward pressure of the mold head, reduces the stress on the guide rod 332, and also provides rolling support for the movable module 62.
