Description

Technical Field

[0001] This utility model relates to the field of paper straw processing, and in particular to a paper straw winding device. Background Technology

[0002] Paper straws are an environmentally friendly alternative, primarily used to replace traditional single-use plastic straws. With increasing global concern about plastic pollution, governments and businesses worldwide are actively seeking alternatives to plastic products. Due to their biodegradable and recyclable properties, paper straws have become one of the main alternatives to plastic straws.

[0003] Chinese Patent Publication No. CN 221049139 U describes "A fully automatic paper straw winding device," which improves the mandrel used for winding. Specifically, to reduce the inner diameter of the produced straw, the shaft base is rotated clockwise, and the connecting belt is wound around the central column. The connecting belt pulls the first and second rotating shaft rods closer to the center. The first and second rotating shaft rods move along the slide groove closer to the center. The first rotating shaft rod drives the rotating shaft bracket closer to the center, and the rotating shaft bracket no longer supports the rotating shaft shell. The second rotating shaft rod drives the rotating shaft shell to retract inward, and the excessively long part of the rotating shaft shell extends into the interior of the other rotating shaft rod. At this time, the interior of the rotating shaft returns to its original state. In this way, the diameter of the rotating shaft mold is adjusted, meeting the needs of producing different types of straws.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] In existing winding devices, the mandrel is relatively long, reaching 2-3m. It is fixed to one end of the rotating shaft housing and the position of the rotating shaft housing is adjusted from this end. However, for the position far from the fixed end, the rotating shaft housing itself does not receive sufficient support, which can easily lead to insufficient rigidity and deformation, thereby affecting the processing quality of the paper straw.

[0006] Therefore, it is necessary to provide a new paper straw winding device to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a paper straw winding device.

[0008] The paper straw winding device provided by this utility model includes a fixing rod, one end of which has a positioning plate, and multiple ring-shaped outer shells that can move radially are provided on the other side of the positioning plate.

[0009] The plurality of said outer shells form a core rod for winding the straw;

[0010] A concentric and rotatable inner support rod is inserted inside the fixed rod. One end of the inner support rod extends into the outer shell and is flush with the other end of the outer shell.

[0011] Multiple adjusting components that support the outer shell are fixed on the inner support rod.

[0012] Preferably, one end of the inner support rod has an end seat, and the other end of the end seat has a hexagonal groove.

[0013] Preferably, the fixing rod is further provided with radially inserted clamping bolts, which can clamp the inner support rod.

[0014] Preferably, the other side of the positioning disk has a plurality of annularly distributed grooves with the length direction along its radial direction, and a slide block is slidably connected inside the groove, and the outer shell is fixed to the slide block by bolts.

An extension plate is provided on the outer circumferential wall of the inner ring seat. A transmission arm is rotatably connected to the extension plate, and a fixed foot is rotatably connected to the other end of the transmission arm. The fixed foot is fixed to the inner wall of the outer shell.

[0016] Preferably, the transmission arm is arc-shaped.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 4 The present invention provides a paper straw winding device, which includes a fixing rod 1, a positioning disk 2 at one end of the fixing rod 1, and a plurality of annularly distributed, radially movable outer shells 7 on the other side of the positioning disk 2.

[0030] Multiple outer shells 7 form a core rod for winding the straw;

[0031] A concentric and rotatable inner support rod 3 is inserted inside the fixed rod 1. One end of the inner support rod 3 extends into the outer shell 7 and is flush with the other end of the outer shell 7.

[0032] Multiple adjusting parts 9 that support the outer shell 7 are fixed on the inner support rod 3.

[0033] It should be noted that in this device, the fixing rod 1 is the fixing structure of the entire core rod structure. That is, the fixing rod 1 should be used in conjunction with the three-jaw chuck. After the fixing rod 1 is stably clamped, it can be driven to rotate to realize the winding operation of the paper straw. Moreover, this setting makes it easier to disassemble and assemble the core rod structure.

[0034] Multiple outer shells 7 are arranged in a ring to form a core rod, which can be used to wind paper straws. At the same time, it can move radially along the positioning disk 2 to change the diameter of the entire core rod, thus facilitating the processing of straws of different diameters.

[0035] The inner support rod 3, together with the adjusting parts 9, supports the outer shell 7. The inner support rod 3 is a solid rod with sufficient rigidity. Multiple adjusting parts 9 are set on the inner support rod 3. The multiple adjusting parts 9 can be set at equal intervals to ensure the support and positioning of the outer shell 7. Therefore, the core rod composed of the outer shell 7 also has greater rigidity and is not easy to deform during use, so as to ensure the processing quality of the paper straw.

[0036] Meanwhile, the adjusting component 9 is the main structure for adjusting the position of the outer shell 7. The adjustment component 9 is driven to move by the rotation of the inner support rod 3, so that the adjusting component 9 can expand outward to adjust the position of the outer shell 7.

[0037] In the embodiments of this utility model, please refer to Figure 2 The inner support rod 3 has an end seat 4 at one end and a hexagonal groove at the other end. The fixing rod 1 is also provided with a radially inserted clamping bolt 5, which can clamp the inner support rod 3.

[0038] It should be noted that in this configuration, tools such as hex wrenches can be inserted into the end seat 4, and then the end seat 4 drives the inner support rod 3 to rotate together. The rotation of the inner support rod 3 realizes the movement of the adjusting component 9, thus allowing the diameter of the mandrel itself to be adjusted. At the same time, the clamping bolt 5 set on the fixing rod 1 can compress the inner support rod 3. Under the compression state, the movement of the inner support rod 3 can be restricted, keeping it in a stable state.

[0039] In the embodiments of this utility model, please refer to Figure 3 On the other side of the positioning disk 2, there are multiple annularly distributed sliding grooves 6 with their length direction along their radial direction. A sliding seat 8 is slidably connected inside the sliding groove 6, and the outer shell 7 is fixed to the sliding seat 8 by bolts.

[0040] It should be noted that the slide block 8 is connected and fixed to the outer shell 7, and slides inside the slide groove 6. It is limited by the slide groove 6. That is, the moving direction of the slide block 8 is along the radial direction of the positioning plate 2, which also limits the movement of the outer shell 7 and improves the adjustment accuracy of the outer shell 7.

[0041] In the embodiments of this utility model, please refer to Figure 4 The adjusting component 9 includes an inner ring seat 91, which is fixed to the inner support rod 3. An extension plate is provided on the outer circumference of the inner ring seat 91. An arc-shaped transmission arm 92 is rotatably connected to the extension plate. A fixed foot 93 is rotatably connected to the other end of the transmission arm 92. The fixed foot 93 is fixed to the inner wall of the outer casing 7.

[0042] It should be noted that the inner ring seat 91 is fixed on the inner support rod 3. Therefore, when the inner support rod 3 rotates, it can drive the inner ring seat 91 to rotate together. Multiple transmission arms 92 are set outside the inner ring seat 91. The other end of the transmission arm 92 is connected to the outer shell 7 through the fixed foot 93. That is, when the inner ring seat 91 rotates, the transmission arm 92 will unfold or close, so that the outer shell 7 can be adjusted through the transmission arm 92.

[0043] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0044] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
