Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring roll production technology, specifically to an automatic spring roll wrapping device. Background Technology
[0002] Spring rolls, also known as spring pancakes or thin pancakes, are a traditional food for Han Chinese festivals and are currently popular both domestically and internationally. However, their processing is quite complicated, especially the filling of the spring roll wrappers, which largely requires manual labor. For workers who have been making spring rolls for a long time, it is difficult to make several spring rolls per minute. At the same time, the labor cost is high and the labor intensity is high. In addition, it is difficult to ensure that each spring roll is the same size when operated manually, which seriously hinders the industrialization of spring roll processing.
[0003] With the continuous development of mechanized food processing, various spring roll manufacturing equipment has emerged. However, among the known forming methods, the dough mixing and wrapper making processes are relatively mature. In the wrapping process, the amount of filling cannot be precisely controlled. If the amount of filling is too small, the spring roll cannot be wrapped into a long cylindrical shape, while if the amount of filling is too large, the roll will break and leak filling, resulting in a low yield and thus increasing production costs.
[0004] Therefore, it is of great importance to design an automatic spring roll wrapping device to solve the above-mentioned defects. Utility Model Content

[0016] In this invention, the design of the quantitative filling component allows for the following process during spring roll wrapping: the spring roll wrapper is placed on a guide frame, which guides it to a pressing mechanism to press it into a uniform thickness. The wrapper is then conveyed to the inside of the wrapping component via a conveyor frame. During this process, a first cylinder is activated, pulling a receiving plate via a connecting rod. This moves the quantitative cylinder below the connector to align with the storage cylinder. The cap automatically closes upon contact with the movable frame. The storage cylinder contains the filling for the spring rolls. Once the quantitative cylinder aligns with the storage cylinder, a measured amount of filling falls into the quantitative cylinder. The first cylinder then pushes the receiving plate, moving the quantitative cylinder above the guide tube, where the cap automatically opens. The measured amount of filling then falls onto the inside of the wrapper. The wrapper, containing the filling, is then drawn into the wrapping component by gravity for wrapping. This method ensures uniform control of the filling amount, avoids waste, reduces production costs, and improves production quality. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example: Please refer to Figures 1-7 This utility model provides a technical solution:
[0027] An automatic spring roll wrapping device includes a machine base 1, a guide frame 2 fixedly installed at the rear end of the top of the machine base 1, a conveyor frame 3 fixedly installed at the front end of the top of the machine base 1, a pressing mechanism 4 installed at the top of the machine base 1 and between the guide frame 2 and the conveyor frame 3, a wrapping component 5 installed on the front of the machine base 1, a quantitative filling dispensing component 6 installed on the front of the machine base 1 and above the wrapping component 5, and a dispensing rack 7 fixedly installed at the bottom end of the front of the machine base 1.
[0028] First, in this embodiment, the specific structure of the quantitative filling dispensing component 6 is as follows:
[0029] The quantitative filling dispensing component 6 includes a support frame 601 fixedly installed on the wrapping component 5. A storage cylinder 602 is fixedly installed at the top of the support frame 601. A connector 603 is threadedly connected to the bottom of the support frame 601. A movable frame 604 is fixedly installed at the bottom of the connector 603. A receiving plate 605 is slidably connected inside the movable frame 604. A quantitative cylinder 606 is fixedly connected to the left end of the receiving plate 605. A cap 607 is rotatably connected to the bottom of the quantitative cylinder 606. A first cylinder 608 is fixedly installed at the rear end of the support frame 601. The output end of the first cylinder 608 is fixedly connected to the right end of the receiving plate 605 via a connecting rod 609. A guide pipe 610 is fixedly connected to the bottom of the support frame 601, below the quantitative cylinder 606. When wrapping spring rolls, the spring roll wrappers are placed on the guide frame 2 and guided by the guide frame 2 to the pressing mechanism 4 to press them into wrappers of uniform thickness. Then, the filling is conveyed to the inside of the wrapping assembly 5 via the conveyor frame 3. During this process, the first cylinder 608 is activated to pull the receiving plate 605 through the connecting rod 609, causing the metering cylinder 606 to move to the bottom of the connector 603 and dock with the storage cylinder 602. During this process, the cap 607 automatically closes when it contacts the movable frame 604. The storage cylinder 602 contains the filling for spring rolls. After the metering cylinder 606 docks with the storage cylinder 602, the metered amount of filling falls into the metering cylinder 606. Then, the first cylinder 608 pushes the receiving plate 605 to move the metering cylinder 606 above the guide pipe 610, and the cap 607 automatically opens. Then, the metered amount of filling falls to the inside of the dough. The dough wrapping the filling falls into the inside of the wrapping assembly 5 under the influence of gravity for wrapping. This allows for even control of the amount of filling used, avoiding waste, reducing production costs, and improving production quality.
[0030] Furthermore, a transparent window 611 is fixedly installed on the outside of the storage cylinder 602, and a cylinder cover 612 is threadedly connected to the top of the storage cylinder 602. A first motor 613 is fixedly installed on the top of the cylinder cover 612, and an auger 614 is fixedly installed on the drive end of the first motor 613 and located inside the cylinder cover 612. The cylinder cover 612 can be opened to add the filling required for spring rolls into the storage cylinder 602. The transparent window 611 on the outside makes it easy to observe the remaining amount of filling and replenish it in time. At the same time, when the storage cylinder 602 discharges filling, the first motor 613 is started to drive the auger 614 to rotate, and the auger 614 pushes the filling out.
[0031] Then, both ends of the receiving plate 605 are slidably connected to the movable frame 604 via guide rails 615. A rubber pad 616 is fixedly connected to the support frame 601 on the right side of the connecting rod 609. When the first cylinder 608 is started, the receiving plate 605 is moved through the connecting rod 609. The receiving plate 605 moves stably under the connection of the guide rails 615. At the same time, the rubber pad 616 protects the connecting rod 609 to prevent it from being damaged by impacting the support frame 601 when it moves.
[0032] Furthermore, the pressing mechanism 4 includes an adjusting frame 401 fixedly installed between the guide frame 2 and the conveyor frame 3. The bottom end of the inner side of the adjusting frame 401 is rotatably connected to a first pressing roller 402. The inner side of the adjusting frame 401 and below the first pressing roller 402 is fixedly installed with a second motor 403, which is connected to the first pressing roller 402 via a sprocket assembly 404. The top end of the inner side of the adjusting frame 401 is rotatably connected to a second pressing roller 405. When wrapping spring rolls, the spring roll dough is placed on the guide frame 2 and guided into the inner side of the adjusting frame 401. The second motor 403 is started and drives the first pressing roller 402 to rotate via the sprocket assembly 404. When the dough passes between the first pressing roller 402 and the second pressing roller 405, it is evenly pressed into the required thickness, thereby ensuring the wrapping quality of the subsequent spring rolls.
[0033] The packaging component 5 includes two sets of guide plates 501 symmetrically installed at the top front of the machine base 1. Rollers 502 are rotatably connected to the front of the machine base 1 below the two sets of guide plates 501. A second cylinder 503 is fixedly installed at the bottom front of the machine base 1, and a connecting frame 504 is fixedly installed at the drive end of the second cylinder 503. A limit roller 505 is rotatably connected to the front of the connecting frame 504 between the two sets of rollers 502. The dough is conveyed to the front end of the machine base 1 via the conveyor frame 3 and then falls... The filling falls onto the two sets of guide plates 501, and then falls into the inside of the dough. Under the action of gravity, it enters between the two sets of rolling rollers 502. The second cylinder 503 pushes up to move the limiting roller 505 to the bottom between the two sets of rolling rollers 502. The dough with filling is supported by the limiting roller 505. Then, the two sets of rolling rollers 502 are started to roll the spring roll in opposite directions until the dough with filling is rolled into a cylindrical shape. Finally, the second cylinder 503 lowers the limiting roller 505 so that the spring roll falls onto the discharge rack 7.
[0034] Secondly, a third motor 506 is fixedly installed inside the machine base 1. Two sets of rollers 502 are fixedly installed with transmission gears 507 at one end inside the machine base 1, and the two sets of transmission gears 507 mesh with each other. The drive end of the third motor 506 meshes with one of the transmission gears 507 through a drive gear 508. The third motor 506 drives the drive gear 508 to rotate, and under the transmission of the transmission gear 507, the two sets of rollers 502 rotate in opposite directions to roll the spring rolls into shape.
[0035] Finally, an installation groove 509 is provided inside the machine base 1 at the position corresponding to the second cylinder 503. The front end of the limiting roller 505 is fixedly connected to the limiting plate 510. The second cylinder 503 is installed and hidden inside the installation groove 509. When the limiting roller 505 moves to the lower part between the two sets of rolling rollers 502, the front end is limited by the limiting plate 510 to prevent it from coming off during spring roll rolling.
[0036] In this embodiment, the specific implementation scenario is as follows: When making spring rolls, the spring roll wrappers are placed on the guide frame 2, and the wrapper is guided by the pressing mechanism 4 to press the wrappers into uniform thickness. Then, the wrappers are conveyed to the inside of the wrapping assembly 5 via the conveyor frame 3. During this process, the first cylinder 608 is activated to pull the receiving plate 605 through the connecting rod 609, causing the metering cylinder 606 to move to the bottom of the connector 603 and dock with the storage cylinder 602. During this process, the cap 607 automatically closes when it contacts the movable frame 604. The storage cylinder 602 contains the filling for the spring rolls. When the metering cylinder 606... After docking with the storage cylinder 602, a measured amount of filling falls into the measuring cylinder 606. Then, the receiving plate 605 is pushed by the first cylinder 608, moving the measuring cylinder 606 above the guide tube 610. The cap 607 then opens automatically, and the measured amount of filling falls onto the inside of the dough. The dough, which is wrapped with the filling, falls into the wrapping component 5 under the influence of gravity for wrapping. This allows for uniform control of the amount of filling used. The entire operation process is simple and convenient. This utility model, through its design, can uniformly control the amount of filling used to avoid waste, reduce production costs, and improve production quality.
