Description

Technical Field

[0001] This utility model relates to the field of noodle production technology, and in particular to a noodle trimming mechanism. Background Technology

[0002] Dried noodles are one of China's traditional noodle foods. As a classic representative of traditional Chinese noodles, dried noodles have been passed down and innovated for thousands of years. With their unique shape and rich variety, they have become a common sight on people's tables. They are mainly made from wheat flour, with the addition of salt, alkali and water. After being hung to dry, they are cut into dried noodles. In modern dried noodle production lines, in order to ensure that the noodles are regular in shape and uniform in quality, the noodle trimming mechanism is a key link. It undertakes the important mission of trimming the edges and optimizing the shape, and is an indispensable core equipment to ensure the quality of finished dried noodles.

[0003] An existing patent (publication number: CN219165559U) discloses "a noodle trimming mechanism, comprising two upright plates, with a horizontal plate welded to the top of both upright plates. A linkage mechanism is mounted on the horizontal plate. The linkage mechanism includes a servo motor, with a gearbox at the end of the output shaft of the servo motor. Transmission rods are connected to both sides of the gearbox, and first transmission wheels are keyed to the transmission rods on both sides. Transmission belts are connected to the first transmission wheels on both sides, and second transmission wheels are connected to the other ends of the transmission belts on both sides. Shafts are connected to the second transmission wheels on both sides, and cutting blades are keyed to the shafts on both sides. This utility model has a linkage mechanism that enables a single power source to drive double-sided cutting blades to cut the noodles, reducing resource consumption and other advantages."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: Most of the existing sheet trimming mechanisms adopt a fixed blade structure, which cannot be flexibly adjusted according to the width of the sheet, resulting in them being only suitable for processing products of a single specification, with poor versatility. When producing diversified products, it is necessary to frequently change equipment, which reduces production efficiency and increases enterprise costs.

[0005] Therefore, those skilled in the art have provided a sheet trimming mechanism to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sheet trimming mechanism. This mechanism uses a dual-axis motor to drive the rotating shaft to operate synchronously. By rotating the screw and connecting rod, the spacing of the cutting blades can be flexibly adjusted, adapting to the trimming needs of sheets of different widths and improving the versatility of the equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A sheet trimming mechanism includes a conveying device, a cutting mechanism at the upper end of the conveying device, a mounting plate, a dual-axis motor fixedly mounted at the front end of the mounting plate, a rotating shaft fixedly mounted at the output end of each of the dual-axis motors, a fixing block fixedly mounted on the side of each of the two rotating shafts near the dual-axis motors, a screw rotatably mounted on the opposite side of each of the two fixing blocks, and a connecting rod threadedly connected to the opposite outer side of each of the two screws.

[0009] Both of the two rotating shafts are slidably provided with rotating rings on their outer sides, and both rotating rings are rotatably provided with connecting blocks on opposite sides. The front end of the mounting plate is slidably provided with two protective frames, and the lower ends of both protective frames are slidably provided with fixing rods.

[0010] Furthermore, two baffles are fixedly installed at the upper end of the conveying device, and the mounting plate is fixedly installed on both sides of the two baffles on opposite sides.

[0011] Furthermore, cutting blades are fixedly installed on the outside of both rotating rings, and the two connecting rods are rotatably mounted on opposite sides of the two cutting blades.

[0012] Furthermore, the lower ends of the two protective frames are slidably disposed on the outer surfaces of the two connecting blocks, and the two rotating shafts are rotatably disposed on opposite sides inside the mounting plate.

[0013] Furthermore, each of the two fixed rods has a wedge fixedly installed at its lower end, and each of the two wedges has a spring fixedly installed at its upper end.

[0014] Furthermore, the upper ends of the two springs are respectively fixedly installed at the lower end of the protective frame, and the outer surfaces of the two springs are respectively sleeved inside the two fixed rods.

[0015] Furthermore, the lower ends of both inclined blocks are located at the upper end of the conveying device, and collection frames are provided on both sides of the lower end of the conveying device.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a sheet trimming mechanism. When the position of the cutting blade needs to be adjusted, the connecting rod is rotated, causing the cutting blade to drive the rotating ring to slide outside the rotating shaft. The sliding of the rotating ring will synchronously drive the connecting block to move, thereby causing the protective frame to slide at the front end of the mounting plate. The movement of the protective frame will push the inclined block at its lower end to slide at the upper end of the conveying device, so that the device can quickly adapt to the trimming needs of sheets of different specifications, enhance the versatility of the equipment, and reduce the cost for enterprises to replace equipment due to changes in product specifications.

[0018] 2. The sheet trimming mechanism proposed in this utility model starts a dual-axis motor when cutting the sheet, driving the rotating shaft to rotate, causing the fixed block to rotate synchronously. This drives the screw and connecting rod to rotate synchronously, and the rotating ring also rotates with the rotating shaft. When the rotating ring rotates, it drives the cutting blade connected to it to rotate synchronously, thereby achieving the cutting of the edge of the sheet. The cut waste is guided into the collection box through the inclined block, achieving the effect of automatic collection. This not only improves the cutting efficiency, but also ensures that the waste is cleaned up in time, avoiding the waste residue from affecting subsequent processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 One embodiment provided by this utility model:

[0028] A sheet trimming mechanism includes a conveying device 1, a cutting mechanism 4 is provided at the upper end of the conveying device 1, the cutting mechanism 4 includes a mounting plate 405, a dual-axis motor 404 is fixedly provided at the front end of the mounting plate 405, a rotating shaft 403 is fixedly provided at the output end of the dual-axis motor 404, a fixing block 411 is fixedly provided on the side of the two rotating shafts 403 near the dual-axis motor 404, a screw 406 is rotatably provided on the opposite side of the two fixing blocks 411, and a connecting rod 407 is threadedly connected to the opposite side of the two screws 406.

[0029] Two rotating shafts 403 are slidably provided with rotating rings 412 on their outer sides. Two connecting blocks 414 are slidably provided on opposite sides of the two rotating rings 412. Two protective frames 402 are slidably provided at the front end of the mounting plate 405. Fixed rods 409 are slidably provided at the lower end of the two protective frames 402. Inclined blocks 408 are fixedly provided at the lower end of the two fixed rods 409.

[0030] Two baffles 2 are fixedly installed at the upper end of the conveying device 1. The mounting plate 405 is fixedly installed on both sides of the two baffles 2 on opposite sides. Cutting blades 413 are fixedly installed on the outside of the two rotating rings 412. Two connecting rods 407 are rotatably installed on opposite sides of the two cutting blades 413. The lower ends of the two protective frames 402 are slidably installed on the outer surface of the two connecting blocks 414. Two rotating shafts 403 are rotatably installed on opposite sides of the mounting plate 405. Springs 410 are fixedly installed at the upper ends of the two inclined blocks 408. The upper ends of the two springs 410 are fixedly installed at the lower ends of the protective frames 402. The outside of the two springs 410 are respectively sleeved inside the two fixed rods 409. The lower ends of the two inclined blocks 408 are both installed at the upper end of the conveying device 1. Collection frames 3 are installed on both sides of the lower end of the conveying device 1.

[0031] Specifically, in actual operation, the conveying device 1 continuously and stably transports the sheet material, providing a continuous processing object for the trimming process. The conveying device 1 is a mature and publicly available technology, therefore, its specific structure and working principle will not be elaborated upon in this paper. The baffle 2 is used to limit the offset of the sheet material during the conveying process to ensure trimming accuracy. When entering the cutting stage, the dual-axis motor 404 at the front end of the mounting plate 405 is started, causing the rotating shaft 403 to rotate. At the same time, the fixed block 411 rotates synchronously, thereby driving the screw 406 and the connecting rod 407 to work together. Simultaneously, the rotating ring 412 slidably disposed outside the rotating shaft 403 also rotates with the rotation of the rotating shaft 403. The rotation of the rotating ring 412 will drive the cutting blade 413 to rotate. The cutting blade 413 uses its sharp edge to efficiently cut the edge of the conveyed sheet. The waste generated by cutting is guided by the inclined block 408 and falls smoothly into the collection frame 3 on both sides of the lower end of the conveying device 1, realizing the automatic collection of waste and effectively avoiding the accumulation of waste from interfering with the production environment and equipment operation. The spring 410 keeps the lower end of the inclined block 408 in contact with the upper end of the conveying device 1. In addition, during use, the outside of the cutting blade 413 is always inside the protective frame 402, which can effectively prevent operators from accidentally contacting the cutting blade 413, reduce the risk of safety accidents, and provide reliable protection for safe production.

[0032] If the position of the cutting blade 413 needs to be adjusted to accommodate different sizes of sheet metal, the operator only needs to rotate the connecting rod 407. Since the connecting rod 407 is threadedly connected to the screw 406, the rotating connecting rod 407 will drive the cutting blade 413 and the rotating ring 412 connected to it to slide smoothly along the axial direction of the rotating shaft 403. The displacement of the rotating ring 412 synchronously drives the connecting block 414 to move, thereby pushing the rear end of the protective frame 402 to slide linearly at the front end of the mounting plate 405. The movement of the protective frame 402 causes the inclined block 408 at its lower end to slide synchronously on the surface of the conveying device 1. Furthermore, the outer surface of the rotating shaft 403 has scale lines, which can provide the operator with an intuitive position reference, enabling them to quickly and accurately adjust the cutting blade 413 to the required position, thus improving the convenience and accuracy of equipment adjustment.

[0033] The entire process, from sheet feeding and cutting to waste collection, is automated, reducing manual intervention, effectively improving production efficiency, lowering labor costs, and meeting the needs of large-scale industrial production. Furthermore, the position of the cutting blade 413 can be precisely adjusted through a simple rotation operation. Combined with the rotating shaft 403 and scale lines, it can accurately adapt to the trimming needs of sheets of different widths and shapes, enhancing the equipment's versatility and applicability. The combination of threaded drive and sliding ensures a smooth and stable adjustment process for the cutting blade 413. The scale lines provide operators with intuitive and convenient adjustment guidance, reducing operational difficulty and shortening adjustment time, while also contributing to improved standardization and normalization of production.

[0034] Working principle: During use, the conveying device 1 continuously conveys the sheet. When the sheet is being cut, the dual-axis motor 404 at the front end of the mounting plate 405 is started. Its output end drives the rotating shaft 403 to rotate. When the rotating shaft 403 rotates, the fixed block 411 rotates accordingly, which in turn drives the screw 406 and the connecting rod 407 to rotate synchronously. At the same time, the rotating ring 412 outside the rotating shaft 403 also rotates with the rotating shaft 403. During the rotation, the rotating ring 412 will synchronously drive the cutting blade 413 connected to it to rotate, thereby cutting the edge of the sheet. The cut waste will be guided into the collection frame 3 through the inclined block 408 for automatic collection.

[0035] When the position of the cutting blade 413 needs to be adjusted, the connecting rod 407 is rotated. Since the connecting rod 407 is threadedly connected to the screw 406, the rotation of the connecting rod 407 will cause the cutting blade 413 to drive the rotating ring 412 to slide outside the rotating shaft 403. The sliding of the rotating ring 412 will synchronously drive the connecting block 414 to move, thereby causing the protective frame 402 to slide at the front end of the mounting plate 405. The movement of the protective frame 402 will cause the inclined block 408 at its lower end to slide at the upper end of the conveying device 1, thereby realizing the position adjustment of the cutting blade 413.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
