Description

Technical Field

[0001] This utility model belongs to the field of willow weaving technology, and more specifically, it relates to a willow branch bending device for willow weaving handicrafts. Background Technology

[0002] When using willow branches for weaving, the most important step is bending the branches to increase their flexibility and facilitate weaving. Currently, bending is often done manually with simple tools. The bending effect depends heavily on the worker's skill, and manual bending results in a limited number of branches at a time, leading to low efficiency. If a large quantity of willow branches is needed, more workers are required, increasing labor costs and reducing profits.

[0003] Patent publication number "CN222200963U" discloses a workbench with two support plates symmetrically fixedly connected to its upper end. A top plate is fixedly connected between the two support plates, and two electric telescopic rods are symmetrically installed at the lower end of the top plate. The telescopic ends of the two electric telescopic rods are jointly fixedly connected to a first connecting plate. A rotating mechanism is provided on the first connecting plate, which includes a first rotating shaft vertically penetrating the first connecting plate. A first motor is installed at the upper end of the first connecting plate. Although the above patent solves the technical problem of using machines to replace manual bending of willow branches, during the bending process, the willow branches may detach from the positioning ring, causing the unformed willow branches to fall out of the forming device, making it difficult to control. Moreover, when clamping one end of the willow branch, the handle still needs to be pulled down manually, which is cumbersome.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

By setting an external fastening device on the outside of the internal rotating device, even if the tail end of the willow branch is separated from the positioning ring when bending the willow, the entire willow branch can be fixed between the internal rotating device and the external fastening device, which is convenient for shaping.

[0006] The aforementioned willow bending device for willow weaving handicrafts includes a base, a willow bending mechanism installed in the middle of the base, and a telescopic device fixedly connected to the base above the willow bending mechanism. The willow bending mechanism includes an external fastening device, an internal rotating device, and a telescopic top plate.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figures 1 to 8 As shown, a willow branch bending device for willow weaving handicrafts includes a base 1, a willow bending mechanism 2 installed in the middle of the base 1, and a telescopic device 3 fixedly connected to the base 1 above the willow bending mechanism 2. The willow bending mechanism 2 includes an external fastening device 201, an internal rotating device 202, and a telescopic top plate 203. The external fastening device 201 includes a base plate 2011, with four protruding plates 2011A evenly fixedly connected around the base plate 2011. Springs 2012 are fixedly connected to two opposite protruding plates 2011A. An irregularly shaped through hole 2011B is opened in the middle of the base plate 2011. The irregularly shaped through hole 2011B is a round hole with rectangular openings on both sides. The main function of the irregularly shaped through hole 2011B is that when the horizontal block 501 on the extended end of the telescopic device 2 5 (described below) intersects with the irregularly shaped through hole 2011B, it can pull the external fastening device 201 downward and separate it from the internal rotating device 202. Multiple rollers 2013 are rotatably connected to the upper outer edge of the chassis 2011. The main function of the rollers 2013 is to keep the willow branch in a bent state while it is rotating with the internal rotating device 202. If the end of the willow branch disengages from the positioning ring 104, it will cause the bending process to malfunction and prevent bending. The rollers 2013 are made of rubber and have multiple patterns on their surface to increase friction. The rubber material will not leave marks on the willow branch, affecting its appearance, and the patterns can better fix the willow branch and prevent it from moving.

[0020] like Figures 3 to 6As shown, the internal rotating device 202 includes a small disc 2021, with a ring of pillars 2022 fixedly connected to the outer edge of the small disc 2021. A large disc 2023 is fixedly connected to the upper part of the pillars 2022. A circular hole 2024 is opened in the middle of the small disc 2021. A lower clamping plate 2025 is fixedly connected to the small disc 2021 above the circular hole 2024. A semi-circular groove is opened in the middle of the lower clamping plate 2025. Through holes 2025A are opened on both sides of the semi-circular groove on the lower clamping plate 2025. A sliding connection is made in the through holes 2025A. A telescopic column 2026B is attached, with a spring 2026A nested around its outer side. An upper clamping plate 2026 is fixedly connected to the upper end of the telescopic column 2026B. A semi-circular groove is formed in the lower center of the upper clamping plate 2026. The upper part of the spring 2026A is fixedly connected to the upper clamping plate 2026, and the lower part is fixedly connected to the lower clamping plate 2025. A lifting plate 2026C is fixedly connected to the lower part of the telescopic column 2026B, located between the lower clamping plate 2025 and the circular hole 2024. The advantages of this design are that the semi-circular groove can accommodate most willow branches of different diameters and hold them without movement. Furthermore, even if the willow branch is too large, it will remain between the upper and lower clamping plates 2026 and can be secured by the contraction of the spring 2026A itself.

[0021] A servo motor 2031 is fixedly connected in the middle of the telescopic top plate 203. The rotating end of the servo motor 2031 passes through the telescopic top plate 203 and is fixedly connected to the large disc 2023, which drives the entire internal rotating device 202 to rotate.

[0022] like Figure 8 As shown, the base 1 includes a base frame 101, a water tank 102 is fixedly connected in the middle of the base frame 101, a limiter 102B is fixedly connected around the inner wall of the water tank 102, a protruding plate 2011A is slidably connected in the limiter 102B, a bracket 102C is fixedly connected above the limiter 102B in the length direction of the water tank 102, the bracket 102C is in the shape of an inverted "L", one end of a spring 2012 is fixedly connected to the bracket 102C, a positioning ring 104 is fixedly connected to the base frame 101 on one side in the width direction of the water tank 102, and a drain pipe 105 is fixedly connected to one side of the bottom of the water tank 102. The drain pipe 105 is normally closed and will only be opened when the internal treatment fluid needs to be replaced. A telescopic pipe 102A is fixedly connected to the middle of the bottom of the water tank 102. The telescopic pipe 102A is connected to the water tank 102. The main reason for setting the telescopic pipe 102A is that the telescopic device 2 5 adopts hydraulic telescopic. If the hydraulic rod directly enters the water tank 102, it will cause contamination to the water tank 102. The telescopic rod 102A plays an isolation role. The extension and retraction of the hydraulic rod of the water tank 102 part will enter the telescopic pipe 102A and will not enter the telescopic device 2 5.

[0023] A servo motor 4 is fixedly connected to the base frame 101 at the bottom of the water tank 102. A telescopic device 5 is fixedly connected to the rotating end of the servo motor 4. The extended end of the telescopic device 5 is slidably connected to the telescopic tube 102A. A horizontal block 501 is fixedly connected to the upper third of the extended end. The horizontal block 501 is located inside the water tank 102. The main function of the horizontal block 501 is to pull the external fastening device 201 downward.

[0024] A base frame 103 is fixedly connected to the base frame 101 directly above the water tank 102. Two telescopic devices 3 are fixedly connected to the base frame 103. The telescopic ends of the telescopic devices 3 pass through the base frame 103 and are fixedly connected to the telescopic top plate 203. A motor through hole 103A is provided in the middle of the base frame 103 to facilitate the passage of the servo motor 2031. The main function of the motor through hole 103A is to facilitate the entry and exit of the servo motor 2031 when the telescopic device 3 drives the internal rotating device 202 to move upward. The height of the servo motor 2031 will affect the upward movement of the internal rotating device 202.

[0025] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0026] Working process: When using this device, first activate the telescopic device 25 to extend and retract upwards, causing the telescopic end of the telescopic device 25 to press against the lifting plate 2026C, separating the upper clamping plate 2026 from the lower clamping plate 2025. From the outside of the device, place one end of the willow branch through the positioning ring 104 onto the lower clamping plate 2025. The telescopic device 25 retracts downwards, and the upper clamping plate 2026 clamps one end of the willow branch under the action of the spring 2026A. Then, activate the servo motor 2031 to drive the internal rotating device 202 to rotate. The bent willow branch will form a circle around the column 2022. The external clamping device 201 on the outside of the internal rotating device 202 assists in bending the willow branch, preventing it from detaching from the positioning ring 104 and disintegrating after the final winding. After all the winding is complete, the telescopic device 3 will drive the internal rotating device 202 to move downwards. The internal rotating device 202 will press against the external fastening device 201 and move downwards until it enters the treatment liquid in the water tank (the treatment liquid is used to quickly shape the willow branches soaked inside; it is commercially available and is a readily available material). After a certain period of time, the telescopic device 3 will drive the internal rotating device 202 to move upwards, and the external fastening device 201 will also move upwards under the action of the spring 2012, tightly surrounding the outside of the willow branch. After the entire willow bending mechanism 2 has come out of the water tank 102, the telescopic device 5 will lift upwards again, lifting the top plate 2026C, separating the upper clamping plate 2026 and the lower clamping plate 2025, and removing one end of the willow branch. Then, under the action of the servo motor 4, the telescopic device 25 rotates 90 degrees, causing the cross block 501 to intersect with the irregular through hole 2011B on the chassis 2011. During the retraction of the telescopic device 25, the external fastening device 201 retracts, and the telescopic device 3 moves upward with the internal rotating device 202, causing the external fastening device 201 and the internal rotating device 202 to separate, thereby taking out the shaped willow branch.

[0027] When the next bending operation is required, the telescopic device 3 simply moves downwards along with the internal rotating device 202, and under the action of the servo motor 2, aligns the hole formed between the upper clamping plate 2026 and the lower clamping plate 2025 with the positioning ring 104. Then, the telescopic device 2 5 extends upwards, and the external fastening device 201 moves upwards back to the default position. The servo motor 4 rotates 90 degrees to make the horizontal block 501 parallel to the irregular through hole 2011B.

[0028] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
