Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically a device for cutting and shaping taro balls to a fixed length and quantity. Background Technology

[0002] Taro balls, a core ingredient in Chinese desserts and snacks, are widely favored by the market for their soft, chewy texture. In their large-scale processing, extrusion cutting is a crucial step, directly determining the finished product's specifications, appearance uniformity, and processing efficiency. With the standardization and large-scale development of the food processing industry, the market demands higher precision in the fixed-length and quantitative cutting of taro balls, as well as greater consistency in finished product quality. Traditional manual cutting and simple mechanical cutting are no longer sufficient for large-scale production needs, necessitating specialized automated cutting and forming equipment to ensure processing quality and capacity.

[0003] Most existing taro ball cutting and forming equipment adopts an extruder combined with a fixed cutting blade assembly. During operation, the taro ball raw material is extruded by the extruder to form a long strip blank, which is continuously output directly from the extrusion die. The external rotary or reciprocating cutter is close to the discharge end of the extrusion die and directly cuts the freshly extruded plastic blank. Some equipment is only equipped with a simple guide tube to limit the long strip blank, without a pre-treatment structure. It relies on the uniform speed of the cutter to achieve fixed-length cutting, thereby completing the initial forming process of the taro ball.

[0004] However, the existing processing equipment has obvious technical defects. The freshly extruded taro ball blanks are soft and highly plastic. When cut directly without hardening treatment, the blanks are easily affected by the shearing force and extrusion force of the cutter, resulting in problems such as extrusion deformation, cut collapse, and uneven length. The precision of fixed-length and quantitative cutting is poor. At the same time, the cut soft taro ball finished products are very prone to sticking together and being deformed under pressure during subsequent stacking, freezing, and transportation, which seriously affects the regularity and quality of the finished products.

[0005] Therefore, it is necessary to provide a taro ball fixed-length and quantitative cutting and forming device to solve the above-mentioned technical problems. Summary of the Invention

Through the coordinated arrangement of a fixed sleeve, a movable sleeve, a coaxially corresponding support cylinder one and a support cylinder two, and a cold air output component, the surface of the taro ball after extrusion is pre-frozen and hardened, which effectively solves the problems of easy deformation and poor fixed-length and quantitative accuracy when directly cutting soft blanks in the prior art.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a taro ball fixed-length and quantitative cutting and forming device, comprising a fixed sleeve, a movable sleeve, an elastic connecting component, and a cutting component.

The number of support cylinders I is the same as the number of support cylinders II, and the plurality of support cylinders I are coaxially arranged in a one-to-one correspondence with the plurality of support cylinders II. A cold air output component is disposed on the inner side of the fixed sleeve. When the elastic connecting component is in a stretched state, a gap is provided between the support cylinders I and II.

[0008] A further configuration of the present invention is as follows: the elastic connection assembly includes a first connecting ring, a second connecting ring, and a spring; the first connecting ring is fixedly fitted onto a fixed sleeve; the second connecting ring is fixedly fitted onto a movable sleeve; one end of the spring is fixedly connected to the fixed sleeve; and the other end of the spring is fixedly connected to the movable sleeve.

[0009] A further feature of the present invention is that: the end of the support cylinder one near the support cylinder two is provided with a mating interface one, and the end of the support cylinder two near the support cylinder one is provided with a mating interface two, both of which are funnel-shaped and arranged opposite to each other.

[0010] A further configuration of the present invention is as follows: the cold air output assembly includes a cold air input pipe and a plurality of jet rings, the number of jet rings being the same as the number of support cylinders one, and the plurality of jet rings being coaxially arranged with the plurality of support cylinders respectively, and the jet rings being disposed in the gap between support cylinder one and support cylinder two, the cold air input pipe being connected to the plurality of jet rings, and the inner side of the jet rings being provided with a plurality of jet holes.

[0011] A further feature of the present invention is that the cold air input pipe is fixedly connected to the fixed sleeve, the cold air input pipe penetrates the side wall of the fixed sleeve, and the cold air input pipe is connected to multiple jet rings through multiple connecting pipes.

[0012] A further feature of the present invention is that an air outlet pipe is fixedly provided on the fixed sleeve, and the air outlet pipe is connected to the inner cavity of the fixed sleeve.

[0013] A further feature of the present invention is that a plurality of mounting plates are fixedly installed on the side of the fixed sleeve away from the movable sleeve, and the mounting plates are provided with mounting holes.

[0014] A further configuration of the present invention is as follows: the cutting assembly includes a blade holder and a plurality of cutting blades, the blade holder is rotatably mounted on the side wall of the movable sleeve away from the fixed sleeve, the plurality of cutting blades are all fixedly connected to the blade holder, and the movable sleeve is provided with a driving assembly for driving the blade holder to rotate.

It allows the taro ball blank to form a hard outer layer before cutting, resisting the shearing and extrusion force of the cutter, avoiding defects such as blank deformation, cut collapse, and uneven length. This significantly improves the uniformity and dimensional accuracy of taro ball cutting, meeting the requirements of fixed-length and quantitative processing for large-scale production. Furthermore, the flexible connecting component allows for adjustable and controllable spacing between support cylinders (one and two), ensuring smooth guidance of the blank in the initial extrusion stage and quickly forming a gap for cold air action, thus optimizing the continuity of the pre-hardening operation.

[0025] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Please see Figures 1-5 In this embodiment of the invention, a taro ball fixed-length and quantitative cutting and forming device includes a fixed sleeve 1, a movable sleeve 2, an elastic connecting component, and a cutting component. The fixed sleeve 1 and the movable sleeve 2 are slidably fitted together, and the movable sleeve 2 is elastically connected to the fixed sleeve 1 through the elastic connecting component. The cutting component is disposed on the side of the movable sleeve 2 away from the fixed sleeve 1. A plurality of support cylinders 6 are fixedly installed on the inner side of the fixed sleeve 1, and a plurality of support cylinders 7 are fixedly installed on the inner side of the movable sleeve 2. The number of support cylinders 6 is the same as the number of support cylinders 7, and the plurality of support cylinders 6 are coaxially arranged in a one-to-one correspondence with the plurality of support cylinders 7. A cold air output component is disposed on the inner side of the fixed sleeve 1. When the elastic connecting component is in a stretched state, a gap is provided between the support cylinders 6 and 7. The end of the support cylinder 6 away from the support cylinder 7 penetrates the side wall of the fixed sleeve 1, and the end of the support cylinder 7 away from the support cylinder 7... One end of the support cylinder 6 penetrates the side wall of the movable sleeve 2. In actual use, the fixed sleeve 1 is installed on the taro ball extruder, and the multiple support cylinders 6 are connected to the extrusion ports of the taro ball extruder. When the taro ball extruder starts working, the movable sleeve 2 is pushed towards the fixed sleeve 1, so that the elastic connecting component is compressed until the ends of the support cylinder 6 and the support cylinder 7 are in contact. The long strip of taro ball extruded by the taro ball extruder passes through the support cylinder 6 and the support cylinder 7 in sequence. Then the movable sleeve 2 is gradually moved away from the fixed sleeve 1 to reset, so that a gap is created between the support cylinder 6 and the support cylinder 7. Cold air is introduced into the chamber inside the movable sleeve 2 and the fixed sleeve 1 through the cold air output component to quickly cool down the long strip of taro ball entering the chamber, so that the outer wall of the taro ball gradually hardens. The taro ball output through the support cylinder 7 is cut by the cutting component.

[0027] This device relies on the sliding fit structure of the fixed sleeve 1 and the movable sleeve 2, combined with the elastic reset characteristics of the elastic connecting component, to achieve adjustable and controllable spacing between support cylinder 1 6 and support cylinder 2 7. During the start-up phase, external force drives the movable sleeve 2 to slide towards the fixed sleeve 1, compressing the elastic connecting component, causing the coaxially corresponding support cylinder 1 6 and support cylinder 2 7 end faces to fit tightly together, forming a continuous and unobstructed guide channel. At this time, the plastic strip taro balls extruded by the taro ball extruder can smoothly pass through this channel, avoiding the bending and material blockage problems that occur in the initial stage of extrusion due to lack of guidance and gap obstruction, ensuring the continuity of the extrusion process. After the taro ball is stably protruding from the second support cylinder 7, the external force is removed, and the elastic connecting component is elastically reset, causing the movable sleeve 2 to move away from the fixed sleeve 1, so that a preset gap is formed between the first support cylinder 6 and the second support cylinder 7. The exposed long strip of taro ball is under the cooling condition of the cold air output component. The cold air quickly covers the outer wall of the taro ball segment, and the surface is rapidly cooled and solidified through forced convection heat exchange, forming a hard shell with a certain structural strength. After the hard shell is formed, the long strip of taro ball is continuously conveyed to the cutting station, where the cutting component completes the fixed-length cutting operation. The entire process realizes the integrated continuous processing of "guided extrusion - gap exposure - cold air pre-hardening - fixed-length cutting".

[0028] This device, through the adjustable support cylinder 1 (6) and support cylinder 2 (7) in conjunction with a cold air pre-cooling and hardening structure, achieves technical optimization in both processing technology and product quality. The core beneficial effects are as follows: First, it improves the accuracy of cutting to fixed length and quantity. By pre-freezing and hardening the surface of the extruded taro balls, the material properties of the plastic taro balls are altered, giving them anti-deformation stiffness. During the cutting process, they can withstand the shearing impact and extrusion force of the cutter 13, eliminating problems such as extrusion deformation, rough edges, and excessive length deviation that occur when cutting soft taro balls. This ensures the uniformity of the specifications of individual taro balls and meets the production requirements for fixed-length and quantitative cutting. Second, it improves the quality of the finished taro balls through pre-hardening. After processing, a dense hard film forms on the surface of the taro balls. During subsequent stacking, freezing, and transportation, this effectively prevents the taro balls from sticking together, collapsing, or deforming under pressure, maintaining the uniformity of the finished product and reducing the defect rate. Thirdly, it optimizes processing adaptability and continuity. The elastic adjustable structure of the movable sleeve 2 and the fixed sleeve 1 takes into account both the guiding and feeding needs in the initial stage of extrusion and the pre-cooling and hardening needs in subsequent processing, adapting to the processing rhythm of continuous taro ball extrusion and improving overall processing efficiency. At the same time, the cold air acts directly on the taro ball segments in the gaps, with strong cooling targeting and high heat exchange efficiency. Compared with overall cooling, it has lower energy consumption and more controllable pre-hardening effect, making it suitable for large-scale food processing scenarios.

[0029] In this embodiment, preferably, the elastic connection assembly includes a first connecting ring 3, a second connecting ring 4, and a spring 5. The first connecting ring 3 is fixedly fitted onto the fixed sleeve 1, and the second connecting ring 4 is fixedly fitted onto the movable sleeve 2. One end of the spring 5 is fixedly connected to the fixed sleeve 1, and the other end of the spring 5 is fixedly connected to the movable sleeve 2. Through the setting of the spring 5, the movable sleeve 2 and the fixed sleeve 1 are elastically connected, so that the movable sleeve 2 moves toward the fixed sleeve 1 when subjected to radial pressure, and returns to its original position when the pressure is removed.

[0030] In this embodiment, preferably, the end of the first support cylinder 6 near the second support cylinder 7 is provided with a first interface 601, and the end of the second support cylinder 7 near the first support cylinder 6 is provided with a second interface 701. Both the first interface 601 and the second interface 701 are funnel-shaped and arranged opposite to each other. The arrangement of the first interface 601 and the second interface 701 allows the taro balls to enter the second support cylinder 7 more smoothly when the first support cylinder 6 and the second support cylinder 7 are connected.

[0031] In this embodiment, preferably, a plurality of mounting plates 17 are fixedly installed on the side of the fixed sleeve 1 away from the movable sleeve 2, and the mounting plates 17 are provided with mounting holes; the mounting plates 17, together with bolts, can install the fixed sleeve 1 on the extruder, and the bolts pass through the mounting holes during installation.

[0032] In this embodiment, preferably, the cold air output assembly includes a cold air input pipe 10 and a plurality of jet rings 8. The number of jet rings 8 is the same as the number of support cylinders 6, and the plurality of jet rings 8 are coaxially arranged with the plurality of support cylinders 6. The jet rings 8 are located in the gap between the support cylinders 6 and the support cylinders 7. The cold air input pipe 10 is connected to the plurality of jet rings 8, and the inner side of the jet rings 8 is provided with a plurality of jet holes 801. The cold air input pipe 10 is fixedly connected to the fixing sleeve 1, and the cold air input pipe 10 passes through the fixing sleeve 1. On the side wall, the cold air input pipe 10 is connected to multiple air jet rings 8 through multiple connecting pipes 11; an air outlet pipe 9 is fixedly installed on the fixed sleeve 1, and the air outlet pipe 9 is connected to the inner cavity of the fixed sleeve 1; the cold air generated by the refrigeration equipment is input into the air jet rings 8 through the cold air input pipe 10 and the connecting pipes 11, and then ejected through multiple air jet holes 801. The ejected cold air acts directly on the taro balls to quickly freeze and harden the surface of the taro balls. Then the gas is discharged through the air outlet pipe 9 and returned to the refrigeration equipment for cyclic refrigeration.

[0033] Please see Figure 3 and Figure 4In this embodiment of the invention, the cutting assembly includes a blade holder 12 and a plurality of cutting blades 13. The blade holder 12 is rotatably mounted on the side wall of the movable sleeve 2 away from the fixed sleeve 1. The plurality of cutting blades 13 are all fixedly connected to the blade holder 12. The movable sleeve 2 is provided with a driving assembly for driving the blade holder 12 to rotate. The driving assembly includes a transmission box 15, a motor 16, and a rotating shaft 14. The transmission box 15 is fixedly connected to the movable sleeve 2 and penetrates the side wall of the movable sleeve 2. The motor 16 is fixedly mounted on the transmission box 15, and the rotating shaft 14... One end of the motor 16 is fixedly connected to the blade holder 12, and the rotating shaft 14 passes through the transmission box 15. The transmission box 15 is equipped with a transmission belt (not shown in the figure) and a transmission wheel (not shown in the figure). The output end of the motor 16 is connected to the rotating shaft 14 through the transmission belt and the transmission wheel. When the output end of the motor 16 rotates, it drives the rotating shaft 14 to rotate through the transmission belt and the transmission wheel. When the rotating shaft 14 rotates, it drives multiple cutters 13 to rotate through the blade holder 12, thereby cutting the taro balls extruded from the support cylinder 7. The rotating shaft 14 rotates at a uniform speed, thereby ensuring the uniformity of the taro ball cutting.

[0034] In this embodiment, preferably, the end of the rotating shaft 14 away from the blade holder 12 is provided with an extension 1401, which extends into the inner side of the fixed sleeve 1. The extension 1401 is provided with multiple heat dissipation fins. Through the provision of the extension 1401 and the heat dissipation fins, the heat generated when the rotating shaft 14 rotates can be quickly dissipated under the action of cold air, so as to quickly cool down the rotating shaft 14, the blade holder 12 and the cutter 13, prevent the cutter 13 from overheating, and ensure the cutting effect.

[0035] Working principle: The working process of this device relies on the sliding fit structure of the fixed sleeve 1 and the movable sleeve 2, and the elastic reset characteristics of the elastic connecting components to achieve the same result. When assembling the device, the fixed sleeve 1 is firmly installed on the taro ball extruder, so that each support cylinder 6 corresponds to and is connected to the extrusion port of the extruder. At the beginning of the operation, the movable sleeve 2 is pushed to slide towards the fixed sleeve 1 by external force, compressing the elastic connecting components until the ends of the support cylinder 6 and the support cylinder 7 are tightly fitted, forming a continuous and through guide channel. At this time, the long strip of plastic taro ball extruded by the extruder can smoothly pass through the support cylinder 6 and the support cylinder 7 along this channel, effectively avoiding the problems of taro ball bending and material blockage in the initial stage of extrusion, and ensuring the continuity and stability of material extrusion.

[0036] After the long taro ball is stably passed through the support cylinder 2 7, the external force is removed, and the elastic connecting component automatically and elastically resets, causing the movable sleeve 2 to move away from the fixed sleeve 1, so that a preset gap is formed between the support cylinder 1 6 and the support cylinder 2 7. At this time, the cold air output component is activated, and cold air is continuously introduced into the inner cavity of the fixed sleeve 1 and the movable sleeve 2 and acts on the exposed taro ball segment at the gap. Through forced heat exchange, the outer wall of the taro ball is quickly hardened and formed, giving the taro ball anti-deformation stiffness. Subsequently, the hardened long taro ball is continuously output from the support cylinder 2 7 and is cut to a fixed length by the cutting component rotating at a uniform speed under the drive of the drive component. The entire process realizes the integrated continuous operation of extrusion guidance, pre-cooling hardening, and fixed-length cutting, ensuring the accuracy and quality of taro ball cutting and forming.

[0037] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
