[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] Combined with attachment Figure 1 and 2 As shown, this embodiment provides a broom bundling machine for bundling bamboo brooms, Achnatherum splendens brooms, or Red Willow brooms. The broom bundling machine of this embodiment includes a machine base 1 and a bundling device 2. The machine base 1 serves as the installation foundation and support structure of the broom bundling machine of this embodiment. The bundling device 2 is mounted on the machine base 1, and the bundling device 2 enables broom bundling operations.

[0039] The bundling device 2 of this embodiment includes a bundling mechanism 3 and a driving mechanism 4; the bundling mechanism 3 of this embodiment includes a plurality of bundling members 5 installed on the machine base 1 at intervals along the circumferential direction, the bundling members 5 having opposite first ends 7 and second ends 8, and the second ends 8 of the plurality of bundling members 5 form a bundling hole 6. It should be noted that the bundling hole 6 is not a completely closed structure. When the driving mechanism 4 drives its aperture to reach the second size described below, the bundling hole 6 is approximately in a closed state.

[0040] In this embodiment, the drive mechanism 4 is connected to the binding member 5 and is used to drive the binding member 5 to change the diameter of the binding hole 6 from a first size to a second size, wherein the first size is larger than the second size. In other words, the drive mechanism 4 can be used to shrink or expand the binding hole 6. When the binding hole 6 shrinks, it can tighten loose bamboo branches, red willow branches, etc. together for a secure bundle. This eliminates the need for manual tying, significantly improving broom production efficiency and freeing up manpower to meet market supply requirements.

[0041] Based on the above structure, this embodiment improves the structure of the binding member 5 to facilitate the contraction of the binding hole 6. Figure 3 As shown, the binding member 5 of this embodiment is provided with a first connecting portion 9 between the first end 7 and the second end 8, and the machine base 1 is provided with a plurality of second connecting portions 10 evenly spaced along the circumferential direction. The first connecting portion 9 and the second connecting portion 10 are connected by a first rotating shaft 13.

[0042] Specifically, the first connecting portion 9 of this embodiment can be an axial hole or other structure that can be used to install a rotating shaft, and the second connecting portion 10 can be a structure that can be used to install a rotating shaft. Both ends of the first rotating shaft 13 are installed in the axial hole, so that the first rotating shaft 13 can rotate, or in other words, the bundling member 5 can rotate around the first rotating shaft 13.

[0043] Furthermore, the bundling piece 5 of this embodiment is provided with a third connecting portion 11 at the first end 7, and the third connecting portion 11 is connected to the driving mechanism 4 through a second rotating shaft 14. Specifically, the driving mechanism 4 is provided with a fourth connecting portion 12, and one end of the second rotating shaft 14 is connected to the third connecting portion 11, and the other end is connected to the fourth connecting portion 12. Similarly, the third connecting portion 11 of this embodiment can also be an axis hole or other structure on which a rotating shaft can be installed, and the fourth connecting portion 12 can be a structure on which a rotating shaft can be installed.

[0044] During operation, the driving mechanism 4 of this embodiment drives the second rotating shaft 14 to move, so that each binding member 5 rotates around the corresponding first rotating shaft 13, thereby completing the expansion and contraction of the binding hole 6.

[0045] Based on the above-mentioned action mode of the bundling member 5, the driving mechanism 4 of this embodiment may include a turntable as shown in the figure, with a hole opened in the middle of the turntable, and a plurality of fourth connecting parts 12 evenly spaced along the circumference of the turntable. The plurality of third connecting parts 11 and the fourth connecting parts 12 are connected by a second rotating shaft 14. The rotation of one turntable can drive all the second rotating shafts 14 and the bundling member 5 to rotate around the first rotating shaft 13, thereby causing the aperture of the bundling hole 6 to change from the first size to the second size, and the rotation of the bundling member 5 can wrap and tighten the bamboo leaves, etc., thereby improving the bundling stability effect.

[0046] The drive mode of the turntable of this embodiment can be automatic or manual. For example, a crank (not shown in the figure) is connected to the turntable, and the crank is turned manually or mechanically, or the turntable is connected to a driving device (motor, etc.) that can output torque, and the driving device is used to drive the turntable to rotate on the base 1.

[0047] In order to further ensure the bundling effect and efficiency, the present embodiment also makes improvements to the structure of the bundling member 5. Figure 2 and 3As shown, the strapping piece 5 of this embodiment includes a mounting arm 15 and a strapping arm 16 connected to each other. The mounting arm 15 of this embodiment is provided with the above-mentioned first connecting portion 9 and third connecting portion 11. The strapping arm 16 of this embodiment is provided with a strapping surface 17 that forms an obtuse angle with the mounting arm 15. Multiple strapping surfaces 17 surround the strapping hole 6.

[0048] In this embodiment, the bundling surface 17 and the bundling arm 16 form an obtuse angle, so that the bundling hole 6 formed by the bundling surface 17 has a surrounding inclined structure, so that the bamboo leaves can be wound and tightened along the inclined direction.

[0049] As a preferred implementation of this embodiment, the bundling arm 16 of this embodiment is provided with a protrusion 18 protruding toward the axial direction of the bundling hole 6 at one end away from the bundling arm 16. The protrusion 18 is designed to prevent other workpieces from approaching the binding wire and to limit the binding wire to the optimal position for tightening.

[0050] In order to prevent the binding members 5 from influencing each other during the rotation process and to enable the binding surfaces 17 of the binding members 5 to fit together as closely as possible, the present embodiment improves the structure of the mounting arm 15 .

[0051] Combined with Figure 2 and 3 As shown, in the circumferential direction of the strapping hole 6, the mounting arm 15 of this embodiment has a first side and a second side opposite to each other, the first side is provided with a first surface 19 and a second surface 20 that form an obtuse angle with each other, and the first surface 19, the second surface 20 and the strapping surface 17 are connected in sequence; the second side is provided with a third surface 21, and the second surface 20 of one of the two adjacent strapping arms 16 is in contact with the third surface 21 of the other strapping arm 16.

[0052] This structure enables two adjacent strapping pieces 5 to fit together, thereby allowing the distance between two adjacent strapping surfaces 17 to be within a smaller range. Moreover, since the first surface 19 and the second surface 20 form an obtuse angle, the second surface 20 of one of the two adjacent strapping arms 16 fits together with the third surface 21 of the other strapping arm 16. When the strapping piece 5 rotates, the second surface 20 can slide along the third surface 21, and the first surface 19 will not affect the rotation of the strapping piece 5.

[0053] Of course, the structural form of the tying piece 5 and the driving mechanism 4 of this embodiment is not limited to this. For example, the driving mechanism 4 is a linear reciprocating motion structure (such as a gas rod, a ball screw, etc.), which drives the tying piece 5 to move linearly through linear motion, thereby making the range of the second end 8 of the tying piece 5 larger or smaller. However, the driving mechanism 4 of this structure is relatively expensive, and each tying piece 5 needs to be equipped with a corresponding driving mechanism 4. Moreover, the tying piece 5 driven by this driving mechanism 4 can only achieve the scaling of the tying hole 6, and cannot be used to wrap and tighten the bamboo leaves, etc., and the tying effect is greatly reduced. Therefore, this embodiment is preferably Figure 1-3 The driving mechanism 4 and the strapping mechanism 3 are shown in FIG.

[0054] Combined with Figure 1 and 2 As shown, the base 1 of this embodiment includes a supporting portion 22 and a mounting portion 23 connected to each other. The mounting portion 23 is located above the supporting portion 22, and the strapping mechanism 3 is mounted on the mounting portion 23. The mounting portion 23 is provided with a first opening 24 coaxial with the strapping hole 6. The aperture size of the first opening 24 is greater than or equal to the first size. The design of the first opening 24 can prevent the mounting portion 23 from affecting the strapping operation.

[0055] Based on the driving mechanism 4 and the strapping mechanism 3 of this embodiment, the mounting portion 23 of this embodiment is a circular box-shaped structure, which includes a bottom wall 25 and side walls 26 arranged around the bottom wall 25 in the circumferential direction; the bottom wall 25 of this embodiment is provided with the above-mentioned first opening 24; a plurality of strapping members 5 are sequentially installed on the bottom wall 25 along the circumferential direction of the bottom wall 25.

[0056] As a preferred implementation of this embodiment, in order to facilitate the bundling operation, the bottom wall 25 of this embodiment is arranged along the vertical direction, and the first opening 24 of this embodiment is coaxially arranged with the bundling hole 6.

[0057] As a preferred embodiment of this embodiment, the broom bundling machine of this embodiment further includes a limiting device 27, which can be Figure 2 As shown in the circular ring structure, the limiting device 27 is provided with a second opening 28 coaxial with the bundling hole 6. Similarly, the aperture size of the second opening 28 is greater than or equal to the first size.

[0058] The limiting device 27 of this embodiment is connected to the side wall 26, and the connection method can be detachably connected by screws or other connecting parts. The limiting device 27 is used to limit the bundling mechanism 3 and the driving mechanism 4 in the installation part 23, so that the entire driving mechanism 4 and the bundling mechanism 3 are located in the box-shaped installation part 23, which not only protects the driving mechanism 4 and the bundling mechanism 3, but also improves the compactness of the entire body structure.

[0059] In addition, the broom bundling machine of this embodiment can also have a cutting device (shown in the figure), which is used to cut the binding wire after bundling. After the binding wire is cut, the bundling hole 6 is driven by the driving mechanism 4 to expand, waiting for the start of the next bundling action, and thus performing a reciprocating action.

[0060] In summary, according to the broom bundling machine provided in this embodiment, the bundling mechanism 3 utilizes the principle of rotational reverse extension, and the thickness and strength of the bundling are uniform, avoiding the traditional manual production that easily damages the bamboo branches and affects the service life of the broom, reducing human resources and improving work efficiency.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
