Description

Technical Field

[0001] This utility model belongs to the field of straw processing, specifically relating to straw dewatering device and straw dewatering system. Background Technology

[0002] With the rapid expansion of the market for milk tea and other freshly prepared beverages, the demand for disposable plastic straws continues to grow, making them an indispensable consumable in daily life. Currently, the production of plastic straws generally employs extrusion molding, a process that mainly includes raw material melt extrusion, shaping and cooling, traction cutting, and packaging. Although the technology is relatively mature, problems still exist in actual production, especially in the crucial stage from the extruder exit to cooling and shaping.

[0003] In the initial cooling stage after extrusion, the molten plastic preform is not yet fully shaped, resulting in poor morphological stability. Existing equipment relies on manual experience for parameter adjustment and control. Improper operation can easily lead to problems such as pipe deformation, eccentricity, surface roughness, or uneven diameter, resulting in a decrease in product qualification rate. In particular, the process of passing the preform through the dewatering device requires time for alignment with the suction tube. Slow alignment speed leads to waste of extruded preforms, wasting both material and time, thus impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a straw dewatering device and a straw dewatering system, which can enable operators to quickly align holes, reduce material waste, and improve production efficiency.

[0005] The technical solution is as follows:

[0006] A straw dewatering device includes multiple air-exiting components that are movably connected. Each air-exiting component has an air inlet and an air outlet that are connected to each other. The inner side of each air-exiting component has a straw-accommodating position, and the air outlet is located on the straw-accommodating position. When the air-exiting components are connected together, the multiple straw-accommodating positions form a straw dewatering space, and the air outlet faces the straw dewatering space.

[0007] In one embodiment, the plurality of air outlet components include at least a first air outlet component and a second air outlet component, the first air outlet component and the second air outlet component being rotatably connected.

[0008] In one embodiment, the straw dewatering space includes a narrow end and a wide end, and the air outlet faces the middle of the straw dewatering space and is inclined toward the wide end.

[0009] In one embodiment, both the first and second air outlet components are provided with air guide grooves, which are respectively connected to the air inlet and the air outlet.

[0010] In one embodiment, multiple air outlets are provided, spaced apart on the straw receiving position.

[0011] In one embodiment, both the first air outlet component and the second air outlet component include a first base and a second base, the air guide groove is formed on the first base, and the second base is fixedly connected to the first base to block the air guide groove.

[0012] In one embodiment, both the air outlet and the air inlet are located on the first base.

[0013] In one embodiment, the straw dewatering device further includes a hinged component, through which the first air outlet component and the second air outlet component are rotatably connected.

[0014] In one embodiment, the venting component is made of metal.

[0015] A straw dewatering system includes straw dewatering devices, wherein at least two straw dewatering devices are provided and arranged in a front-to-back configuration.

[0016] The technical solution provided by this utility model has the following advantages and effects:

[0017] During the tube drawing process, the tube preform extruded from the extruder is drawn out and cooled with water. The preform then begins to solidify, forming a straw with water adhering to its surface. Next, it enters the dehydration step. The air outlet of the straw dehydration device is opened, exposing the straw receiving position. The straw is placed directly on the straw receiving position. Then, multiple air outlet components are combined to complete the tube alignment process. At this point, the straw is within the straw dehydration space, completing the alignment. After alignment, air is introduced through the air inlet, and the air is sprayed out through the air outlet towards the straw dehydration space. Within this space, the straw is blown dry by the airflow, removing the water adhering to its surface. In this design, the air outlet components can be disassembled, allowing the straw to be placed directly on the straw receiving position and then reassembled during alignment, thus avoiding the straw passing through small holes. In conventional alignment operations, inexperienced operators often spend a lot of time and waste materials, and even experienced operators require considerable time for alignment. The hole-setting method in this solution allows both skilled and unskilled workers to quickly complete the hole-setting operation, thus improving production efficiency. Attached Figure Description

[0026] To facilitate understanding of this utility model, specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0027] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0028] Unless otherwise specified or defined, the term "connected" as used herein can mean either direct or indirect connection.

[0029] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0030] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0031] See Figure 1 and Figure 2 As shown, the straw dewatering device includes multiple air outlet components, which are movably connected. Each air outlet component has an air inlet 11 and an air outlet 12, which are connected. The inner side of each air outlet component is provided with a straw receiving position 16, and the air outlet 12 is located on the straw receiving position 16. After the air outlet components are connected, the multiple straw receiving positions 16 form a straw dewatering space 30, and the air outlet 12 faces the straw dewatering space 30.

[0032] During the tube drawing process, the tube preform extruded from the extruder is drawn out and cooled with water. The preform then begins to solidify, forming a straw with water adhering to its surface. Next, the straw enters the dehydration step. The air outlet component of the straw dehydration device is opened, exposing the straw receiving position 16. The straw is placed directly on the straw receiving position 16. Then, multiple air outlet components are combined to complete the tube alignment operation. At this point, the straw is within the straw dehydration space 30, completing the alignment. After alignment, air is introduced through the air inlet 11, and the air is sprayed out through the air outlet 12 towards the straw dehydration space 30. Within the straw dehydration space 30, the airflow blows away the water adhering to its surface, and the straw dries. In this design, the air outlet components can be disassembled, so during alignment, the straw can be directly placed on the straw receiving position 16, and then the air outlet components can be reassembled to complete the alignment, thus avoiding the straw passing through small holes. In conventional hole-setting operations, inexperienced operators often spend a lot of time and waste materials, while even experienced operators need time to set the holes. However, the hole-setting method in this solution allows for quick completion of the operation regardless of the operator's skill level, thus improving production efficiency.

[0033] See Figure 1 and Figure 2 As shown, specifically, the plurality of air-exhausting components include at least a first air-exhausting component 10 and a second air-exhausting component 20, which are rotatably connected. This solution specifically employs two air-exhausting components, namely the first air-exhausting component 10 and the second air-exhausting component 20. The first air-exhausting component 10 and the second air-exhausting component 20 are rotatably connected to open and close the straw drainage space 30. At this time, the first air-exhausting component 10 and the second air-exhausting component 20 are symmetrically arranged, resulting in a larger open straw drainage space 30, facilitating straw placement.

[0034] In other embodiments, a third air outlet component may also be included. The second air outlet component 20 and the third air outlet component are rotatably connected to the first component. When it is necessary to open the initial water space of the straw, the second air outlet component 20 and the third air outlet component are rotated to release the splicing relationship between the first air outlet component 10, the second air outlet component 20 and the third air outlet component, and then the straw is placed in.

[0035] like Figure 2 and Figure 3 As shown, the first air outlet component 10 and the second air outlet component 20 are rotatably connected by the hinge component 40. The hinge component 40 enables the two components to be rotatably connected, and the connection has good reliability.

[0036] In this design, the hinge component 40 rotatably connects the first air outlet component 10 and the second air outlet component 20 using a hinge mechanism. Of course, other connection methods can also be used.

[0037] See Figure 4 and Figure 5 As shown, the straw dewatering space 30 includes a narrow end 31 and a wide end 32. The air outlet 12 faces the middle of the straw dewatering space 30 and is inclined towards the wide end 32. This arrangement controls the direction of airflow, ensuring that the airflow is sprayed obliquely from the air outlet 12 towards the middle of the straw dewatering space 30 and flows along the narrow end 31 to the wide end 32. Therefore, water droplets from the straw also flow from the narrow end 31 to the wide end 32 under the action of the airflow. Since the straw moves from the wide end 32 to the narrow end 31, the arrangement of the air outlet 12 ensures that water droplets do not easily enter the side of the narrow end 31, i.e., the side of the straw after dewatering. Specifically, the narrow end 31 and the wide end 32 gradually transition, making the straw dewatering space 30 have a flared, funnel-shaped opening.

[0038] See Figure 4 As shown, a groove is provided on the side of the narrow end 31 away from the wide end 32. This groove can be used to install a guide tube to guide the movement of the straw.

[0039] See Figures 3 to 5 As shown, both the first air outlet component 10 and the second air outlet component 20 are provided with air guide grooves 13, which are respectively connected to the air inlet 11 and the air outlet 12. Multiple air outlets 12 are provided, spaced apart on the straw receiving position 16. Air enters through one air inlet 11, flows into the air guide groove 13, and then into the air outlet 12 connected to the air guide groove 13, thus achieving air supply from one air inlet 11 to multiple air outlets 12. Furthermore, the air inlets 11 are spaced apart around the axis of the straw dewatering space 30, ensuring that the air blows around the circumference of the straw during dewatering, thus eliminating dead zones in the straw's dewatering process.

[0040] See Figure 3As shown, both the first air outlet component 10 and the second air outlet component 20 include a first base 14 and a second base 15. The air guide groove 13 is formed on the first base 14, and the second base 15 is fixedly connected to the first base 14, sealing the air guide groove 13. This arrangement facilitates the processing of the air guide groove 13. The air guide groove 13 is processed on the surface of the first base 14, and then the second base 15 is used to seal the air guide groove 13. At this time, the air guide groove 13 only communicates with the air inlet 11 and the air outlet 12.

[0041] Specifically, the first base 14 and the second base 15 have matching fixing holes on their outer sides, and the first base 14 and the second base 15 are fixedly connected by nails.

[0042] In addition, a sealing strip can be installed between the first base 14 and the second base 15, which surrounds the air guide groove 13 to improve the airtightness of the air guide groove 13.

[0043] See Figure 3 and Figure 5 As shown, specifically, both the air outlet 12 and the air inlet 11 are located on the first base 14. This configuration only requires machining the first base 14, and precision control only needs to ensure the precision of the first base 14, thus reducing the machining difficulty.

[0044] Of course, in other embodiments, the air inlet 11, the air outlet 12, and the air guide groove 13 may be formed on the first base 14 and / or the second base 15.

[0045] See Figure 5 As shown, a stepped surface 151 is provided on the side of the second base 15 that is spliced ​​with the first base 14. The stepped surface 151 can prevent the second base 15 from deforming at the splice point on the side of the suction tube water removal space 30, thus affecting the airtightness of the splice between the first base 14 and the second base 15.

[0046] Both the first venting component 10 and the second venting component 20 are made of metal. Since the density of metal is greater than that of plastic, the first venting component 10 and the second venting component 20 can fit together under the action of gravity after being spliced ​​together.

[0047] In other embodiments, a latch may be provided to lock the assembled first air outlet component 10 and second air outlet component 20.

[0048] The straw dewatering system includes at least two straw dewatering devices arranged in a front-to-back configuration. These two devices further ensure effective dewatering of the straws.

[0049] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
