Technical Field
[0001] This utility model relates to an egg roll forming device in the field of food processing machinery, specifically a multi-station egg roll forming device. Background Technology
[0002] Egg rolls, as a traditional snack, have won widespread popularity worldwide for their crispy texture and diverse flavors. As a typical baked good, the production process of egg rolls mainly includes several steps such as ingredient mixing, baking and shaping, rolling into a roll, and cooling. Among these, the shaping step is a crucial one and plays a decisive role in the final quality of the egg roll.
[0003] Traditional egg roll forming primarily relies on manual operation. While manual forming offers advantages in flexibility and customization, it is inefficient and struggles to guarantee consistent product quality, significantly limiting large-scale egg roll production. With the development of the food industry, semi-automatic and fully automatic egg roll forming equipment has gradually replaced manual operation, becoming the mainstream method of egg roll production. However, existing semi-automatic egg roll forming equipment still has some shortcomings in practical applications, especially in the batch production stage. Some equipment can only perform single-station forming, meaning it can only form one egg roll at a time, greatly limiting production efficiency. Furthermore, the forming mold design of some equipment is not reasonable enough, and the mold replacement process is cumbersome and time-consuming, which to some extent restricts the diversification of egg roll products. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a multi-station egg roll forming device, which can be used to solve the defects in the above-mentioned technical background.
[0005] The technical problem solved by this utility model is achieved by the following technical solution:
[0006] A multi-station egg roll forming device includes a rotating forming disk. The bottom of the rotating forming disk is driven by a motor to rotate around the axis of the rotating forming disk. N groups of working positions are evenly arranged on the surface of the rotating forming disk with the central axis as the reference, where N is an integer greater than or equal to 2. Each group of working positions includes four working unit arranged in sequence, which correspond to the raw material feeding position, hot pressing position, forming holding position, and shaping and demolding position, respectively.
[0007] The rotating forming disk has 4N forming mold components formed on its annular surface. Each forming mold component corresponds to a work station unit position and can switch the work station unit positions between the same group of work stations and between different groups of work stations by rotating the rotating forming disk.
[0008] The molding die assembly includes a fixed half-die and a movable half-die. At least one of the fixed half-die and the movable half-die is a heating die. The movable half-die is driven by a die drive mechanism to realize the opening and closing action of the movable half-die, thereby cooperating with the fixed half-die to complete the hot pressing molding of the egg roll raw material.
[0009] As a further limitation, the rotation of the rotating forming disk is controlled by a combination of relays and stepper motors. The relays are used to control the interval of the rotating forming disk's rotation, and the stepper motors are used to control the rotation angle and speed of the rotating forming disk, so as to achieve precise switching of the forming mold assembly between working units, thereby ensuring the continuity and stability of the egg roll forming process.
[0010] As a further limitation, the number N of working positions set on the surface of the rotary forming disk is preferably 1 to 4.
[0011] As a further limitation, the rotary forming disc is provided with a feeding device for adding liquid to the forming mold assembly outside the raw material feeding position; the amount of liquid added by the feeding device at one time is quantitatively adjustable.
[0012] As a further limitation, the molding die assembly includes an L-shaped assembly frame, the fixed half-die is fixedly assembled on the horizontal side of the L-shaped assembly frame, and the fixed half-die is connected to the movable half-die via a hinge on the side of the rotating molding disk near the center of the fixed half-die; the vertical side of the L-shaped assembly frame is correspondingly arranged on the side of the center of the rotating molding disk, and a gas strut is hinged on the vertical side as a die driving mechanism, the other end of the gas strut is hinged to the movable half-die, and the movable half-die is driven to open and close by the extension and retraction of the gas strut;
[0013] The L-shaped assembly frame has an integral detachable structure on the surface of the rotary forming disc;
[0014] The fixed half-mold and the movable half-mold are detachable assembly structures on the L-shaped assembly frame.
[0015] As a further definition, the movable half-mold body is a heated mold body.
[0016] As a further limitation, the heating mold and the mold drive mechanism are connected to the hot pressing molding electronic control unit, so as to control the molding temperature and molding time of the heating mold through the hot pressing molding electronic control unit, so as to ensure the stability and accuracy of the egg roll molding process.
[0017] Beneficial Effects: This utility model discloses a multi-station egg roll forming device. Based on multi-station egg roll forming technology, its core component is a rotating forming disc, enabling simultaneous egg roll forming at multiple stations. Each station is equipped with multiple independently operable forming molds. During operation, the forming disc rotates at a preset speed, allowing each mold to sequentially undergo batter application, forming, and baking. This design enables efficient mass production of egg rolls in a short time, significantly improving production efficiency and flexibly adapting to the production needs of egg rolls of different sizes and shapes. Simultaneously, the multi-station design greatly simplifies the mold replacement process; simply remove the old mold from the forming disc and install the new one. This improvement not only saves replacement time but also provides convenience for producing different types of egg roll products. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0022] See Figure 1 , Figure 2 A preferred embodiment of a multi-station egg roll forming apparatus includes a main unit and two feeding devices as structural accessories. The main unit is supported at its bottom by a main unit frame 9, while the two feeding devices are positioned opposite each other on either side of the main unit, with their bottoms supported by a feeding device frame 13. Both the main unit frame 9 and the feeding device frame 13 have disc-shaped stabilizing feet 12 at their base, which increase the overall stability of the equipment.
[0023] In this embodiment, the feeding device, which is a structural accessory, includes a hopper 2. The top surface of the hopper 2 is open and is closed by an openable hopper cover to prevent dust or foreign objects from entering the hopper. When the hopper cover is open, the feeding operation can be performed.
[0024] An automatic feeding device is connected to the discharge position at the bottom of the hopper 2. This automatic feeding device includes a feeding pump 3 and a valve plate linked to the feeding pump 3. The feeding pump 3 and the valve plate are controlled by an electronic control unit to drive the egg roll raw materials in the hopper 2 for quantitative feeding. The end of the automatic feeding device is connected to a feeding nozzle 5, which can be connected to a feeding port 6 set on the adjustable plate frame 4 through a hose (not shown) to achieve quantitative addition of batter to the forming mold assembly 7 on the main unit. In actual operation, the operator can precisely control the amount of batter added to the forming mold assembly each time by adjusting the pumping rate of the feeding pump 3 and the opening size of the feeding nozzle 5, thereby ensuring that each egg roll has a consistent thickness and weight during forming.
[0025] Furthermore, the adjustable plate frame 4 allows the position of the feeding port 6 to be flexibly adjusted according to actual needs. Specifically, the adjustable plate frame 4 is mounted on a horizontal rotating shaft, which is fixedly connected to the lever 1. By rotating the lever 1, the angle of the adjustable plate frame 4 at the corresponding horizontal position can be adjusted. This design not only improves the accuracy and efficiency of batter addition but also makes the feeding process more flexible and convenient, further enhancing the production capacity and adaptability of the entire egg roll forming device.
[0026] In this embodiment, the host machine has a horizontally arranged rotating forming disk 8 on the host machine frame 9. The rotating forming disk 8 is a metal disk structure, and eight forming mold components 7 are evenly arranged on the circumference of the disk surface. These eight forming mold components 7 are divided into two groups. Each group of forming mold components 7 includes four components, which correspond to the raw material feeding position, hot pressing position, forming holding position and shaping demolding position, respectively.
[0027] A stepper motor is fixedly mounted at the bottom center of the rotary forming disc 8. The output shaft of the stepper motor is connected to the central axis of the rotary forming disc 8 via a coupling, thereby driving the rotary forming disc 8 to rotate around its central axis. Through the rotation of the rotary forming disc 8, the eight forming mold components 7 can switch sequentially between different working units to achieve a continuous egg roll forming process.
[0028] The structural style of each molding die component 7 is as follows: Figure 2As shown, the assembly includes an L-shaped assembly frame 18 as a fixed assembly structure. The L-shaped assembly frame 18 is structurally reinforced between its two right-angled sides by diagonal braces 22. Simultaneously, an assembly seat 23 is provided on the outer side of the horizontal side of the L-shaped assembly frame 18, allowing the L-shaped assembly frame 18 to be assembled as a whole on the rotary forming disk 8 via the assembly seat 23. A fixed half-mold 21 and a movable half-mold 20 are movably assembled on the L-shaped assembly frame 18. One or both of the fixed half-mold 21 and the movable half-mold 20 are heating molds, and the temperature of the heating molds is controlled by the forming mold electrical control 14. The fixed half-mold 21 is fixedly assembled to the horizontal side of the L-shaped assembly frame 18, while the movable half-mold 20 is hinged to the side of the fixed half-mold 21 closest to the center of the rotary forming disk 8. The vertical side of the L-shaped assembly frame 18 is positioned at the center of the rotary forming plate 8, and a gas strut 16 is hinged to the vertical side via a hinge support 19 as a mold driving mechanism. The other end of the gas strut 16 is hinged to the movable half-mold 20 via the hinge support 19. When the gas strut 16 extends or retracts, it drives the movable half-mold 20 to open and close, thereby cooperating with the fixed half-mold 21 to complete the hot pressing forming of the egg roll raw material.
[0029] Specifically, in this embodiment, taking the four forming mold components 7 on one side of the viewing angle as an example, position A corresponds to the raw material feeding position, position B corresponds to the hot pressing forming position, position C corresponds to the forming holding position, and position D corresponds to the shaping and demolding position. The feeding device is correspondingly set next to position A. The forming mold component 7 is in the starting position at position A. When the forming mold component 7 is in position A, the movable half mold body 20 is in the open state. At this time, the feeding device will automatically add a quantitative amount of egg roll raw material into the fixed half mold body 21 of the forming mold component 7. After the egg roll raw material is added, the rotating forming plate 8 rotates counterclockwise. During the counterclockwise rotation to position B, the movable half mold body 20 closes. At this time, the heating mold body begins to hot press the egg roll raw material. Subsequently, the forming mold component 7 moves from position B to position C, and the forming holding is performed during this period to ensure that the egg roll is fully cured in the mold. Finally, the forming mold component 7 moves from position C to position D. During this process, the gas strut 16, which is the mold driving mechanism, drives the movable half mold body 20 to open, so that the cooked egg roll can be demolded and shaped. Subsequently, the molding die assembly 7, which remains open, performs another molding cycle in the second half of the cycle and continues to repeat.
[0030] This process automates and makes the egg roll forming process continuous through the continuous rotation of the rotating forming disc 8.
[0031] In order to limit the movement of the movable half-mold 20 during the opening and closing process, the L-shaped assembly frame 18 is equipped with a buffer spring 15 in the middle of the vertical side by a buffer spring support 17. The buffer spring 15 is arranged horizontally and can be stopped by the stop block 24 on the back side against the surface of the buffer spring 15 when the movable half-mold 20 is opened to the maximum position.
[0032] In this embodiment, the main unit has a reserved mounting position for the electrical control box on the inner side of the main unit frame 9. The electrical control box 11 installed in this position contains various electrical components that realize the functions of the main unit. These electrical components work together through a preset electrical control program to realize the automated control of the entire egg roll forming process. An operation panel 10 is provided on one side of the electrical control box 11. The operation panel 10 is equipped with a touch screen and several operation buttons, allowing the operator to input control commands through it. In practical applications, the operator only needs to put the egg roll raw materials into the hopper 2 of the feeding device and set the relevant process parameters through the operation panel 10, such as molding temperature, molding time, and feeding amount. After that, the equipment will automatically perform a series of operations such as quantitative addition of batter, hot pressing, shaping and holding, and demolding, thereby efficiently completing the mass production of egg rolls and further improving the ease of use and operating efficiency of the equipment.
[0033] To further enhance the automation level and production efficiency of the equipment, the heating mold and the mold drive mechanism are integrated into the forming mold electrical control system 14 for unified control. The forming mold electrical control system 14 communicates with the host in the electrical control box 11, and can use preset electrical control programs to precisely adjust the molding temperature and molding time of the heating mold, ensuring precise control of the heating state of the heating mold and the extension and retraction of the gas strut 16, thereby ensuring the stability and accuracy of the egg roll forming process.
[0034] In addition, the rotation of the rotating forming plate 8 is precisely controlled by a combination of relays and stepper motors to achieve precise switching of the forming mold assembly 7 between working units, thereby ensuring the continuity and stability of the egg roll forming process.

Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
