Description

Technical Field

[0001] This utility model relates to the field of food processing, and more specifically, to a wrapping mechanism for an egg roll forming machine. Background Technology

[0002] Egg rolls, a popular snack, rely heavily on the rolling and shaping process during production, which is crucial for their appearance, crispness, and yield. The core function of the egg roll forming machine's rolling mechanism is to tightly and evenly roll the baked, flat egg roll wrappers using mechanical motion. The performance of this mechanism directly affects the tightness of the rolled egg rolls, the consistency of their shape, and the overall efficiency of the production line, making it an indispensable component of automated egg roll production equipment.

[0003] However, some existing egg roll wrapping mechanisms use a single cylinder or rack and pinion to drive the laying platform. This driving method is prone to speed fluctuations and inertial impacts during start-up, shutdown, and operation, resulting in unstable platform movement. Consequently, the egg roll wrappers experience uneven stress during rolling, leading to problems such as inconsistent rolling tightness, wrinkling, and even breakage, which seriously affects the product qualification rate. In addition, while some complex mechanisms can achieve rolling, their transmission systems are redundant and have numerous parts, which not only increases manufacturing costs and equipment size but also increases subsequent maintenance difficulty and failure rate, hindering stable production line operation and cost control. Therefore, we propose a wrapping mechanism for an egg roll forming machine to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a rolling mechanism for an egg roll forming machine. It synchronously drives the forming roller and stable pull rope through a single drive motor, and actively propels the laying platform by the meshing of gears and racks. At the same time, an auxiliary system consisting of belt drive, winding roller and pull rope applies a stable reverse traction force to the laying platform, effectively suppressing speed fluctuations and inertial impacts during equipment operation, ensuring the stability and uniformity of the egg roll rolling process, thereby significantly improving the consistency and quality of product forming.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] A wrapper-rolling mechanism for an egg roll forming machine includes a base. A set of symmetrical slide bars is fixedly connected to the top of the base. A laying platform is provided directly above one end of the base, and the surface of the laying platform is inclined. A set of symmetrical sliding grooves are provided at the bottom of the laying platform, and the sliding grooves are adapted to the slide bars. The laying platform is slidably connected to the surface of the base through the sliding grooves and slide bars. A connecting frame is fixedly connected to the middle of one side of the base, and a stabilizing mechanism is fixedly connected to the top of the connecting frame. The output end of the stabilizing mechanism is fixedly connected to the wrapper-rolling mechanism.

[0007] Furthermore, the roll forming mechanism includes a drive motor, the output end of which passes through the connecting frame and is sequentially fixedly connected to a pulley, a drive gear, and a forming roller. The bottom end of the drive gear is provided with a drive rack, and the drive gear and the drive rack mesh with each other.

[0008] Furthermore, the drive rack is fixedly connected to one side of the laying platform, the forming roller has the same width as the laying platform, the forming roller is located directly above the laying platform, and the distance between the forming roller and the highest point of the laying platform is the thickness of the egg roll skin.

[0009] Furthermore, a drive wheel is provided directly below the pulley, and the pulley and the drive wheel are connected by a drive belt. The drive wheel is movably connected to the outside of the connecting frame via a rotating shaft.

[0010] Furthermore, the stabilizing mechanism includes a winding roller, one end of which is fixedly connected to the axis of the transmission wheel away from the connecting frame via a connecting shaft, and a pull rope is wound around the outer side of the winding roller.

[0011] Furthermore, the stabilizing mechanism also includes a support frame, the bottom end of which is fixedly connected to the middle of the rear end of the base, and the top end of which is fixedly connected to two guide wheels.

[0012] Furthermore, the end of the pull rope away from the winding roller passes through the hubs of two guide wheels and is fixedly connected to the middle of the rear end of the laying platform. Several anti-winding frames are fixedly connected to the end of the base near the pull rope, and the ends of the anti-winding frames away from the bottom are all sleeved on the outside of the pull rope.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, the forming roller and the stable pull rope are driven synchronously by a single drive motor. The active propulsion of the laying platform is achieved by the meshing of gears and racks. At the same time, the auxiliary system composed of belt drive, winding roller and pull rope is used to apply a stable reverse traction force to the laying platform, which effectively suppresses speed fluctuation and inertial impact during equipment operation, and ensures the stability and uniformity of the egg roll skin rolling process, thereby significantly improving the consistency and quality of product forming. (2) This scheme has a compact and reasonable layout. The forming roller, laying platform and transmission system are highly integrated on the base. Precise guidance is achieved through the precise cooperation of the slide bar and the slide groove. The guide wheel and anti-winding frame ensure that the pull rope transmission trajectory is stable and reliable, thereby improving the degree of automation, reducing the difficulty of operation, and effectively reducing the intensity of manual operation. It is especially suitable for the continuous batch production of egg roll food. Attached Figure Description

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please see Figure 1 - Figure 4 A wrapper-rolling mechanism for an egg roll forming machine includes a base 1. A set of symmetrical slide bars 2 are fixedly connected to the top of the base 1. A laying platform 3 is provided directly above one end of the base 1, and the surface of the laying platform 3 is inclined. A set of symmetrical sliding grooves 4 are provided at the bottom of the laying platform 3, and the sliding grooves 4 are adapted to the slide bars 2. The laying platform 3 is slidably connected to the surface of the base 1 through the sliding grooves 4 and the slide bars 2. A connecting frame 5 is fixedly connected to the middle of one side of the base 1, and a stabilizing mechanism 6 is fixedly connected to the top of the connecting frame 5. A wrapper-rolling mechanism 7 is fixedly connected to the output end of the stabilizing mechanism 6.

[0018] Example 2: In view of the above embodiment 1, further description is provided, see reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 The egg roll forming mechanism 7 includes a drive motor 701. The output end of the drive motor 701 passes through the connecting frame 5 and is sequentially and fixedly connected to a pulley 702, a drive gear 703, and a forming roller 704. A drive rack 705 is provided at the bottom end of the drive gear 703, and the drive gear 703 and the drive rack 705 mesh with each other. The drive rack 705 is fixedly connected to one side of the laying platform 3. The forming roller 704 has the same width as the laying platform 3 and is located directly above the laying platform 3. The distance between the forming roller 704 and the highest point of the laying platform 3 is the thickness of the egg roll skin. A transmission wheel 706 is provided directly below the pulley 702, and the pulley 702 and the transmission wheel 706 are connected by a transmission belt. The transmission wheel 706 is movably connected to the outside of the connecting frame 5 through a rotating shaft.

[0019] After the drive motor 701 is started, its output end synchronously drives the pulley 702, drive gear 703 and forming roller 704 to rotate. The drive gear 703 meshes with the drive rack 705 fixed on one side of the laying platform 3, converting the rotational motion into linear power that pushes the laying platform 3 to slide smoothly along the slide bar 2 of the base 1. The forming roller 704, which maintains a precise distance from the laying platform 3, generates relative motion with the moving egg roll skin during rotation, thereby gradually rolling up and shaping the flat egg roll skin. At the same time, the pulley 702, which is coaxial with the drive gear 703, transmits power to the transmission wheel 706 through the transmission belt, providing synchronous power for the subsequent stabilizing mechanism 6, ensuring precise coordination between the rolling and translational movements.

[0020] Example 3: In view of the above embodiments 1 and 2, further description is provided, please refer to... Figure 1 , Figure 2 and Figure 3 The stabilizing mechanism 6 includes a winding roller 601. One end of the winding roller 601 is fixedly connected to the axis of the transmission wheel 706 away from the connecting frame 5 via a connecting shaft. A pull rope 602 is wound around the outside of the winding roller 601. The stabilizing mechanism 6 also includes a support frame 603. The bottom end of the support frame 603 is fixedly connected to the middle of the rear end of the base 1, and two guide wheels 604 are fixedly connected to the top end of the support frame 603. The end of the pull rope 602 away from the winding roller 601 passes through the hubs of the two guide wheels 604 and is fixedly connected to the middle of the rear end of the laying platform 3. Several anti-winding frames 605 are fixedly connected to the end of the base 1 near the pull rope 602, and the ends of the anti-winding frames 605 away from the bottom end are all sleeved on the outside of the pull rope 602.

[0021] When the transmission wheel 706 is driven to rotate by the belt pulley 702, the winding roller 601, which is coaxial with it, also rotates synchronously, continuously and uniformly winding up the pull rope 602 wound on it. The pull rope 602 is precisely turned by the guide wheel 604 on the support frame 603, fixing one end of it to the rear end of the laying platform 3, thereby forming a constant tension, actively pulling the laying platform 3 to move smoothly. The anti-winding frame 605 ensures that the pull rope 602 remains orderly during the winding and unwinding process, preventing it from getting tangled or deviating from the predetermined track, further ensuring the stability and continuity of the entire rolling process.

[0022] Based on the above embodiments 1, 2 and 3, the working principle is further described; in use, the egg roll skin to be processed is laid flat on the surface of the laying platform 3, the drive motor 701 is started, and the pulley 702, drive gear 703 and forming roller 704 are driven to rotate slowly and synchronously. The drive gear 703 meshes with the drive rack 705 fixed on one side of the laying platform 3, and pushes the laying platform 3 to slide smoothly along the surface of the base 1 through the cooperation of the slide groove 4 and the slide bar 2. During this process, the forming roller 704 maintains a preset distance from the surface of the laying platform 3 equal to the thickness of the egg roll skin. As the laying platform 3 moves, the forming roller 704 gradually rolls up the beginning of the egg roll skin and completes the rolling and shaping of the entire egg roll skin in continuous relative motion. Meanwhile, the pulley 702 drives the transmission wheel 706 to rotate via the transmission belt. The transmission wheel 706 drives the winding roller 601 to wind and gather the pull rope 602. The pull rope 602 is guided by the guide wheel 604 and positioned by the anti-winding frame 605. Its end pull platform 3 maintains uniform speed movement, effectively avoiding the impact of speed fluctuations on the quality of the rolled skin and ensuring a stable and continuous forming process.

[0023] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
