Description

Technical Field

[0001] This utility model relates to the field of pearl tapioca pearl production technology, specifically to a powder suction device. Background Technology

[0002] In the production process of tapioca pearls, the powder suction device is used to remove excess starch powder from the surface of the tapioca pearls or to suck up the starch in the powder hopper and discharge it into the coating device to coat the tapioca pearls with powder, so as to ensure the appearance and quality of the product.

[0003] In existing technologies, starch powder is typically drawn up using a straw and a nozzle. Driven by negative pressure, the starch powder is carried by the airflow through the nozzle into the straw and is eventually transported to a designated location (such as a residual powder collection bin or a powder coating device), thus enabling rapid extraction or transport of starch.

[0004] However, traditional straws have smooth inner walls and fixed diameters, while starch powder particles are fine and easily agglomerate. When the starch powder flows in the straw with the airflow, it tends to accumulate inside the straw during the suction process, especially at the bends of the straw and the connection with the nozzle and collection mechanism, where blockages are likely to occur. Once a blockage occurs, the machine needs to be stopped for cleaning, which affects the continuity of production and increases the cost of manual maintenance. Utility Model Content

[0005] In view of this, the present invention provides a powder suction device, which can break down starch powder agglomerates by setting a vibration component on the outside of the suction tube, and make the inner wall vibrate at high frequency through continuous vibration, thereby providing kinetic energy for powder flow, reducing resistance, reducing starch accumulation at the bends and joints of the suction tube, avoiding blockage, reducing downtime for cleaning, ensuring continuous production, and reducing labor costs.

[0006] To solve the above-mentioned technical problems, this utility model provides a powder suction device, including a straw body, a suction nozzle at one end of the straw body, the suction nozzle being trumpet-shaped to increase the powder suction area, the suction nozzle being connected to one end of the straw body via a flange, and an elastic silicone ring being fixedly connected between the mating surfaces of the two flanges.

[0007] A vibration component is provided on the outer wall of the straw body. The vibration component is used to prevent the straw body from becoming blocked by continuous vibration. The vibration component is a high-frequency micro-vibration motor.

[0008] The vibration component is connected to the outer wall of the straw body by a fastener, which is a clamp embedded in the grooves on both sides of the high-frequency micro-vibration motor.

[0009] A sponge pad is fixedly connected to the outer wall of the straw body, and an anti-slip pad is fixedly connected to the outer wall of the sponge pad.

[0010] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0011] 1. Prevents clogging and ensures continuous production: By installing a vibration component (such as a high-frequency micro-vibration motor) on the outer wall of the straw body, continuous vibration generates high-frequency vibration on the inner wall of the straw. This not only breaks up the agglomeration of starch powder but also provides kinetic energy for powder flow, significantly reducing flow resistance. This reduces the accumulation of starch at the bends of the straw and at the connection with the nozzle or collection mechanism, effectively preventing clogging, reducing the number of downtime cleanings caused by clogging, ensuring the continuity of tapioca pearl production, and reducing labor maintenance costs.

[0012] 2. Improved powder absorption efficiency and applicability: The suction nozzle adopts a trumpet-shaped design, which increases the powder absorption area and improves the absorption efficiency of starch powder. It is especially suitable for scenarios involving the absorption of powders dispersed over a large area. Furthermore, the size of the trumpet opening can be adapted to the diameter of tapioca pearls, ensuring efficient powder absorption while avoiding the accidental absorption of tapioca pearls. In addition, the vibration component uses a high-frequency micro-vibration motor. Its high-frequency vibration characteristics prevent clogging and avoid the risk of dust explosion caused by high temperatures generated during vibration, making it suitable for the characteristics of starch powder.

[0013] 3. Stable connection and easy maintenance: The vibration component is fixed to the straw body with clamps, which are embedded in the grooves on both sides of the high-frequency micro-vibration motor. This fixing method eliminates the need for drilling holes in the straw body, preventing powder leakage and accommodating straws of different diameters, enhancing the device's versatility. The nozzle and straw body are connected by a flange, and with the help of an elastic silicone ring, a tight seal is achieved to prevent powder spillage. This also absorbs vibration displacement, preventing the nozzle from cracking due to long-term vibration, and facilitates quick disassembly and maintenance of the nozzle.

[0014] 4. Optimized user experience and device stability: The sponge pad on the outside of the straw body can effectively absorb the vibration energy generated by the vibration component, reduce the transmission of vibration to other parts of the equipment and the operator's hands, reduce noise and equipment wear, and prevent loosening of connecting parts. The anti-slip pad on the outside of the sponge pad increases friction when manually adjusting the position of the straw to prevent slipping, improve the safety and accuracy of operation, and also prevent the straw body from shifting due to vibration when placed, ensuring the stability of powder suction.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] A powder suction device, such as Figure 1 , 2 As shown: It includes a straw body 101, which is connected to the powder suction device via a flange. The starch powder is sucked into the straw body 101 by components such as the negative pressure generator on the powder suction device. A nozzle 102 is provided at one end of the straw body 101. The nozzle 102 can expand the powder suction range, so that the starch powder can be quickly sucked into the collection box inside the powder suction device.

[0021] Furthermore, the nozzle 102 is funnel-shaped to increase the powder suction area (the gradually expanding structure of the funnel mouth significantly increases the inlet cross-sectional area of ​​the nozzle 102, allowing the nozzle 102 to cover a larger area of ​​powder surface), thereby improving powder suction efficiency. When suctioning dispersed powder, the wide-mouth design can reduce powder residue caused by the small area of ​​the nozzle 102, and improve the suction coverage. However, when starch powder and tapioca pearls are stored together in the same storage box, the maximum diameter of the nozzle 102 must be smaller than the diameter of the tapioca pearls.

[0022] like Figure 2 As shown: The suction nozzle 102 is connected to one end of the suction tube body 101 via a flange, which makes it easy to quickly disassemble and assemble the suction nozzle 102 when it needs to be replaced or maintained. An elastic silicone ring is fixedly connected between the mating surfaces of the two flanges.

[0023] The elastic silicone ring can absorb vibration displacement through continuous elastic deformation, maintain a tight seal between the sealing surfaces, prevent powder leakage due to loosening caused by vibration, and prevent vibration from being transmitted to the thin-walled area of ​​the nozzle 102, preventing the end of the nozzle 102 from cracking due to long-term vibration and extending its service life.

[0024] like Figure 1 As shown: A vibration component (a pneumatic vibrator, an ultrasonic transducer, etc.) is provided on the outer wall of the straw body 101. The vibration component is used to prevent the straw body 101 from becoming blocked by continuous vibration.

[0025] Continuous vibration causes the inner wall of the straw to vibrate, preventing starch granules from clogging the pipe or at bends. Furthermore, the vibration energy is converted into powder kinetic energy, significantly reducing the flow resistance of the starch powder.

[0026] Furthermore, the vibration component is a high-frequency micro-vibration motor 103. The high-frequency vibration of the high-frequency vibration motor can break up the agglomerates without causing dust explosions due to high temperatures generated by the vibration.

[0027] like Figure 1 , 2 As shown: The vibration component is connected to the outer wall of the straw body 101 by a fastener (the fastener can also be connected by welding or magnetic base), so that the high-frequency vibration motor can be connected to the outer wall of the straw body 101 to avoid falling off due to high-frequency vibration.

[0028] Furthermore, the fastener is a clamp 104, which is embedded in the grooves on both sides of the high-frequency micro-vibration motor 103, so that the high-frequency micro-vibration motor 103 can adapt to straw bodies 101 of different diameters and to equipment of different production lines.

[0029] Using clamp 104 for external locking eliminates the need to drill holes in the straw, preventing starch powder from leaking out of the opening, and allowing for quick disassembly and assembly when maintenance or replacement of the high-frequency micro-vibration motor 103 is required.

[0030] like Figure 3 As shown: A sponge pad 105 is fixedly connected to the outer wall of the straw body 101. The sponge pad 105 has good elasticity and deformation ability, and can effectively absorb the vibration energy generated by the vibration component (such as the high-frequency micro-vibration motor 103) when it is working.

[0031] This not only reduces the transmission of vibration to other parts of the equipment or the operator's hands, reducing noise and overall vibration loss of the equipment, but also prevents the suction tube body 101 from loosening with other connecting parts (such as flanges) due to continuous vibration, thus ensuring the stability of the device.

[0032] like Figure 1 , 3 As shown: An anti-slip pad 106 is fixedly connected to the outer wall of the sponge pad 105. When manual assistance is needed to adjust the position of the straw or move the device, the anti-slip pad 106 can increase the friction between the hand and the straw body 101, prevent slipping due to sweaty hands or device vibration, and improve the safety and accuracy of operation.

[0033] When the straw body 101 needs to be temporarily placed on a flat surface such as a workbench, the anti-slip mat 106 can increase the friction with the placement surface, preventing the straw body 101 from sliding and shifting due to slight collisions or vibrations, thus reducing interference with the powder suction work.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
