Description

Technical Field

[0001] This utility model relates to the field of dicing machine technology, and in particular to a three-dimensional dicing machine with adjustable size. Background Technology

[0002] As a core piece of equipment in the food processing industry, 3D dicing machines are widely used for the standardized cutting of ingredients such as fruits, vegetables, meat, and seafood. The flexibility of dicing size, cutting precision, and degree of automation directly affect food production efficiency and finished product quality. With the food processing industry developing towards diversification, refinement, and large-scale production, the market is placing higher demands on the adaptability, processing precision, and operational efficiency of dicing machines. They need to achieve rapid switching between multiple size specifications, uniform finished product particle size, and fully automated continuous operation to meet the production needs of different products and reduce labor costs.

[0003] Patent CN219705368U discloses a three-dimensional dicing machine with adjustable size, including a base, a dicing box fixedly connected to the outside of the base, an L-shaped plate fixedly connected to the outside of the base near the dicing box, a drive motor fixedly connected to the outer wall of the L-shaped plate and directly above the dicing box, the output end of the drive motor passing through the side wall of the L-shaped plate and fixedly connected to a first hydraulic rod support, the output end of the first hydraulic rod support fixedly connected to a first hydraulic rod, the output end of the first hydraulic rod fixedly connected to an L-shaped mounting plate, and a first dicing assembly disposed on the L-shaped mounting plate. This application, by being able to adjust the distance between the first cutting blade and the second cutting blade, can cut fruits, vegetables and meats into diced pieces of different sizes, making it highly applicable.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] This equipment achieves different dicing specifications by adjusting the blade spacing, aiming to improve applicability. However, in actual application, it lacks synchronous adjustment and guiding structure, resulting in large dispersion in blade spacing adjustment, long switching time for specifications, and a lack of wide-range continuous adjustment capability. It also lacks material position detection and action timing matching mechanisms, making the blades prone to shaking, leading to large finished product size errors and a high breakage rate. Furthermore, it relies on manual operation of the cutting action, lacks an independent discharge channel and parameter storage function, resulting in low continuous operation efficiency and difficulty in meeting the needs of refined and large-scale production. To solve the above problems, we propose a three-dimensional dicing machine with adjustable dimensions. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, a three-dimensional dicing machine with adjustable dimensions includes a stainless steel frame 1. A conveying component is provided on the inner side of the stainless steel frame 1. A feed hopper 2 is fixedly connected to the front end of the stainless steel frame 1. A C-shaped fixing frame 3 is fixedly connected to the upper end of the feed hopper 2. A sensor is provided on the inner side of the C-shaped fixing frame 3. A lifting mechanism 4 is installed at the rear end of the feed hopper 2 to drive the longitudinal cutting component to rise and fall. An adjustment mechanism 5 for adjusting the cutting size is installed on the inner side of the lifting mechanism 4. A moving mechanism 6 for driving the transverse cutting component to move is installed on the inner side of the C-shaped fixing frame 3. A PLC controller and an industrial intelligent gateway are provided on the inner side of the stainless steel frame 1. The PLC controller is used to store preset dicing specification parameters and control the frequency modulation speed. The industrial intelligent gateway constitutes an Internet of Things communication interface and supports connection with a digital system to realize remote monitoring.

[0025] In this embodiment, the lifting mechanism 4 includes a first motor 41 installed at the rear end of the feed hopper 2. The output shaft of the first motor 41 is fixedly connected to a first sprocket 42. A chain 43 is meshed with the outer side of the first sprocket 42. A second sprocket 44 is meshed with the inner side of the chain 43. A turntable 45 is fixedly connected to the inner side of the second sprocket 44 through a rotating shaft.

[0026] Specifically, the first motor 41 provides a power source for the lifting mechanism 4. Through the meshing transmission of the first sprocket 42 and the second sprocket 44, the rotational power of the first motor 41 is stably transmitted to the turntable 45, driving the turntable 45 to rotate synchronously, providing power support for the subsequent lifting action of the moving plate 46. The transmission ratio of the sprocket chain 43 transmission structure is stable, which can avoid slippage failure during power transmission.

[0027] In this embodiment, two symmetrical grooves are provided on the outer side of the feed hopper 2. A movable plate 46 is slidably connected to the inner side of the groove of the feed hopper 2. An arc-shaped groove is provided on the outer side of the movable plate 46. The inner side of the groove of the movable plate 46 is rotatably connected to the outer side of the turntable 45. Two symmetrical first connecting rods 47 are fixedly connected to the upper end of the movable plate 46. The upper ends of the two first connecting rods 47 are fixedly connected to one of the two bases 48. Two second connecting rods 49 are fixedly connected to the upper ends of the base 48. The upper ends of the second connecting rods 49 are fixedly connected to the mounting housing 410.

[0028] Specifically, the chute of the feed hopper 2 provides vertical guidance and limit for the moving plate 46. When the turntable 45 rotates, it moves along the arc-shaped chute trajectory of the moving plate 46, converting the rotational motion into the vertical lifting motion of the moving plate 46. The first connecting rod 47 and the second connecting rod 49 form a linkage support structure to transmit the lifting power of the moving plate 46, drive the base 48 and the mounting shell 410 to lift synchronously, and then drive the adjustment mechanism 5 in the mounting shell 410 to realize the longitudinal cutting feed action.

[0029] In this embodiment, the adjustment mechanism 5 includes a mounting bracket 51 fixedly connected to the inner side of the mounting housing 410. A second motor 52 is mounted on one side of the mounting bracket 51. A cam shaft 53 is fixedly connected to the output shaft of the second motor 52. A cam groove 54 is provided around the outer side of the cam shaft 53. A plurality of sliding shafts 56 are slidably connected to the outer side of the cam groove 54. A mounting block 55 is fixedly connected to the outer side of each sliding shaft 56. A first slide rod 57 is slidably connected to the inner side of the mounting block 55. Both ends of the first slide rod 57 are fixedly connected to the mounting bracket 51. A cutting blade 58 is fixedly connected to the lower end of each mounting block 55. The lower end of the cutting blade 58 is slidably connected to the base 48.

[0030] Specifically, the mounting bracket 51 provides a mounting support base for each component of the adjustment mechanism 5; the second motor 52 drives the camshaft 53 to rotate, and the cam groove 54, through sliding cooperation with the sliding shaft 56, drives multiple mounting blocks 55 to move synchronously and equidistantly in a straight line along the first slide rod 57; the first slide rod 57 acts as a guide and limiter to ensure that the moving trajectory of the mounting blocks 55 is accurate and without deviation; the mounting blocks 55 synchronously drive the cutting blades 58 to slide along the base 48, so as to realize the precise adjustment of the spacing between the cutting blades 58 to adapt to the dicing size requirements of different specifications. The cutting blades 58 are made of SUS420 martensitic stainless steel and the surface is passivated by nitric acid.

[0031] In this embodiment, the moving mechanism 6 includes a first bracket 61 fixedly connected to the C-shaped fixed frame 3. A first cylinder 62 is installed at the upper end of the first bracket 61. The output shaft of the first cylinder 62 passes through the C-shaped fixed frame 3. A sliding groove is provided at the upper end of the C-shaped fixed frame 3. A cutter head 63 is slidably connected to the inner side of the sliding groove of the C-shaped fixed frame 3. The upper end of the cutter head 63 is fixedly connected to the output shaft of the first cylinder 62.

[0032] Specifically, the first bracket 61 provides a stable mounting support point for the first cylinder 62; the first cylinder 62 serves as a power source, and the extension and retraction of its output shaft drives the cutter head 63 to reciprocate vertically along the slide groove of the C-shaped fixing frame 3; the cutter head 63 is responsible for performing the final vertical cut on the material after longitudinal and transverse cutting, so that the material forms regular cubic particles.

[0033] In this embodiment, the moving mechanism 6 further includes a second bracket 64 fixedly connected to the outside of the C-shaped fixing frame 3. A second cylinder 65 is mounted on the outside of the second bracket 64. The output shaft of the second cylinder 65 is fixedly connected to another mounting housing 410 of the two mounting housings 410.

[0034] Specifically, the second bracket 64 is used to fix and support the second cylinder 65, ensuring the stability of its output shaft extension and retraction. The second cylinder 65 serves as the power source for transverse cutting feed. The extension and retraction of its output shaft drives the corresponding mounting housing 410 and internal adjustment mechanism 5 to move horizontally and linearly, thereby driving the transverse cutting blade 58 to perform transverse cutting of the material that has been longitudinally cut into blocks. The adjustment mechanism 5 and the moving mechanism 6 work together to form a centrifugal cutting system, improving cutting efficiency and uniformity.

[0035] In this embodiment, two symmetrical second slide rods 66 are fixedly connected to the outer side of the other base 48 of the two bases 48, and the outer sides of the two second slide rods 66 are slidably connected to the inner side of the C-shaped fixing frame 3.

[0036] Specifically, the second slide bar 66 connects the base 48 corresponding to the transverse adjustment mechanism 5 and the C-shaped fixing frame 3, providing guidance and limiting for the horizontal movement of the base 48 and the mounting housing 410, preventing deviation and shaking during the transverse cutting feed process, and ensuring the accuracy and stability of the transverse cutting.

[0037] It should be noted that this utility model is a three-dimensional dicing machine with adjustable dimensions. During use, the spacing of the two sets of adjustment mechanisms 5 (horizontal and longitudinal) is adjusted according to the required dicing specifications. The second motor 52, installed on the outside of the mounting frame 51, is started, and its output shaft drives the camshaft 53 to rotate at a constant speed. When the camshaft 53 rotates, its outer cam groove 54 drives the mounting block 55 through the sliding shaft 56, causing the mounting block 55 to move synchronously and equidistantly along the guide trajectory of the first slide rod 57, expanding or contracting at equal intervals. The mounting block 55 synchronously drives the cutting blades 58 below to slide smoothly along the surface of the base 48 until the blade spacing is adjusted to the preset size, completing the parameter setting of the dicing width and length. Then, the material to be diced is evenly placed on a non-uniform surface. On the conveying component inside the stainless steel frame 1, after the equipment is started, the conveying component smoothly conveys the material to the area below the C-shaped fixed frame 3 at a preset speed. The sensor inside the C-shaped fixed frame 3 detects the material signal in real time and then triggers each cutting mechanism to start according to the preset sequence. After the sensor signal is triggered, the first motor 41 starts, and its output shaft drives the first sprocket 42 to rotate. The first sprocket 42 drives the second sprocket 44 to rotate synchronously through the chain 43. The second sprocket 44 drives the turntable 45 to rotate through the rotating shaft. The turntable 45 moves along the arc-shaped slide groove on the outer side of the moving plate 46, thereby driving the moving plate 46 to move up and down smoothly along the slide groove at the rear end of the feed hopper 2 through the slider. The moving plate 46 drives the base 48 through the first connecting rod 47. 8. The second connecting rod 49 drives the mounting housing 410 and the longitudinal adjustment mechanism 5 to rise and fall synchronously, and the longitudinal cutting blade 58 completes the longitudinal strip cutting of the conveyed material. The material after longitudinal strip cutting continues to be conveyed forward with the conveying component. When the material enters the transverse cutting area, the sensor triggers a signal again, driving the second cylinder 65 installed on the outside of the second bracket 64 to start. The output shaft of the second cylinder 65 pushes the corresponding mounting housing 410 and the transverse adjustment mechanism 5 to feed horizontally. At this time, the base 48 connected to the transverse adjustment mechanism 5 drives the second slide rod 66 to slide smoothly along the reserved hole on the inner side of the C-shaped fixing frame 3, and the transverse cutting blade 58 completes the transverse block cutting of the strip material. After longitudinal and transverse cutting The material is in sheet form. Then, the sensor drives the first cylinder 62 at the top of the first support 61 to start. The output shaft of the first cylinder 62 drives the cutter head 63 to move vertically downward along the slide groove at the top of the C-shaped fixed frame 3, completing the vertical cutting of the sheet material from top to bottom, and finally forming regular cubic particles. The diced material falls through the independent discharge port added below the frame to achieve centralized collection and avoid mixing with the material to be processed. During the entire processing, the conveying speed of the conveying component and the action sequence of each cutting mechanism are precisely matched by a preset program. The sensor provides real-time feedback on the material position to ensure that the cutting action is continuous and the dicing size is uniform. After the cutting is completed, each mechanism automatically resets and waits for the next batch of material to trigger, realizing continuous operation.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
