Description

Technical Field

[0001] The invention relates to the technical field of bamboo strip processing, in particular to a water bath device for improving the flexibility of bamboo strips. Background Art

[0002] Before weaving, bamboo strips usually need to be soaked in liquid medicine to increase their flexibility and insect resistance. Generally, bamboo strips are soaked in a liquid medicine pool. In order to completely soak the bamboo strips, the longer the bamboo strips, the larger the volume of the liquid medicine pool needs to be. The applicable range of the liquid medicine pool is limited. At the same time, the liquid medicine pool suitable for long bamboo strips requires more liquid medicine to completely immerse the bamboo strips, which easily causes a waste of soaking liquid medicine.

[0003] Most of the existing water bath devices for soaking bamboo strips are made by bending the bamboo strips and inserting them into the water bath equipment to meet the needs of a small-volume water bath device for soaking long bamboo strips. Although the long bamboo strips can be introduced into the small-volume water bath device for soaking, most of them cannot ensure that the force bending degree of the bamboo strips is consistent during soaking. This makes the tension at different places on the surface of the bamboo strips different when soaking, so that the degree of immersion of the medicine solution at different places of the bamboo strips is inconsistent, which may make it impossible to achieve consistent flexibility at different places of the bamboo strips after soaking. In addition, most of them cannot adjust the bending degree of the bamboo strips soaked in the water bath equipment, and cannot adapt to the processing of bamboo strips with different flexibility requirements.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0034] A water bath device for improving the flexibility of bamboo strips comprises a soaking tube 1 and bamboo strips 4. A feed trough 2 is provided at the upper end of the soaking tube 1. The soaking tube 1 is provided with:

[0035] An inner mounting tube 17, which is rotatably mounted in the middle of the soaking tube 1 and can rotate in the soaking tube 1;

[0036] The support unit is provided with multiple groups and is evenly surrounded by the outer side of the inner mounting tube 17 in a circular shape. The maximum straight-line distance between the support unit and the inner mounting tube 17 can be adjusted. The support unit can rotate in the soaking cylinder 1 along with the inner mounting tube 17. The rotation of the support unit can drive the bamboo strips 4 entering the soaking cylinder 1 through the feed trough 2 to be wound around the outer side of the support unit;

[0037] The external limiting device is slidably arranged on the outside of the soaking cylinder 1 and at the edge of the feed trough 2. The external limiting device can clamp the bamboo strips 4 and can slide on the surface of the soaking cylinder 1 as the internal mounting tube 17 rotates.

[0038] In the present invention, the bamboo strips 4 are clamped on the external limiting device and one end is introduced into the soaking cylinder 1 through the feeding trough 2. One end of the bamboo strips 4 introduced into the soaking cylinder 1 is fixed on the surface of the supporting unit, and then the bamboo strips 4 are pulled into the soaking cylinder 1 as the internal mounting tube 17 rotates, and the bamboo strips 4 are wound around the surface of the supporting unit during the pulling process. During the winding process, the external limiting device can synchronously slide on the surface of the soaking cylinder 1, so that the bamboo strips 4 can be evenly distributed on the surface of the supporting unit during the winding process, avoiding the bamboo strips 4 from being repeatedly wound at the same position, thereby ensuring that the curvature of the bamboo strip surface is consistent at various locations during soaking through the supporting unit, and ensuring that the surface flexibility of the processed bamboo strips 4 is uniform. In the present invention, the maximum distance between the support unit and the inner mounting tube 17 can be adjusted. During soaking, the curvature of the surface of the bamboo strips 4 during soaking can be adjusted by adjusting the size of the maximum distance. The greater the distance between the support unit and the inner mounting tube 17, the smaller the curvature of the bamboo strips 4 when they are wrapped around the surface of the support unit. During actual soaking, the greater the surface curvature of the bamboo strips 4 during soaking, the greater the surface tension of the bamboo strips 4, the more thoroughly the liquid is immersed, and the higher the flexibility of the finished bamboo strips 4.

[0039] Among them, the support unit includes a threaded tube 19, an internal threaded rod 20 and a support member 21. The threaded tube 19 is provided with two groups and is symmetrically arranged at the two ends of the inner mounting tube 17. The threaded tube 19 is threadedly connected with the internal threaded rod 20. A support member 21 is fixedly installed between the ends of the internal threaded rod 20 away from the inner mounting tube 17. The outer surface of the support member 21 is set to be an arc shape. Telescopic rods 26 are fixedly installed at both ends of the support member 21 of one group of support units. A side connecting plate 25 is fixedly installed at one end of the telescopic rod 26 away from the support member 21. A clamping rod 22 is fixedly installed between the side connecting plates 25. The clamping rod 22 and the support member 21 can clamp and fix the bamboo strips 4. After the bamboo strips 4 are introduced into the soaking cylinder 1 through the feed trough 2, one end of the bamboo strips 4 enters between the clamping rod 22 and the support member 21, and one end of the bamboo strips 4 is clamped and fixed by the clamping rod 22 and the support member 21. The inner mounting tube 17 rotates to pull the bamboo strips 4 into the soaking cylinder 1 through the clamping rod 22 and the support member 21. The inner threaded rod 20 is threadedly connected with the threaded tube 19, and the threaded tube 19 rotates to interact with the inner threaded rod 20. The threaded tube 19 rotates in the reverse direction to drive the inner threaded rod 20 away from the inner mounting tube 17, thereby making the support member 21 away from the inner mounting tube 17, so that the surface curvature of the bamboo strips 4 wrapped around the surface of the support member 21 becomes smaller, and the threaded tube 19 rotates forward to drive the support member 21 close to the inner mounting tube 17. At this time, the curvature of the bamboo strips 4 wrapped around the surface of the support member 21 becomes larger.

The user can drive the inner extension shaft 18 to rotate through the adjustment handle 16, the rotation of the inner extension shaft 18 drives the driving bevel gear 28 to rotate, and the rotation of the driving bevel gear 28 can drive the threaded tube 19 to rotate through the driven bevel gear 27.

[0041] The external limiting device includes an upper threaded rod 6 and a movable limiting member 5. The upper threaded rod 6 is rotatably mounted on the soaking cylinder 1. The movable limiting member 5 is threadedly connected to the upper threaded rod 6. A transmission assembly is provided between the upper threaded rod 6 and the inner mounting tube 17. The transmission assembly can drive the upper threaded rod 6 to rotate while driving the inner mounting tube 17 to rotate. The upper threaded rod 6 rotates and interacts with the movable limiting member 5, thereby driving the movable limiting member 5 to slide on the surface of the soaking cylinder 1.

[0044] Among them, a gear ring 10 is rotatably installed on the outer side of one end of the soaking cylinder 1, and an inner lower tooth 12 and an inner upper tooth 13 are arranged on the inner side of the gear ring 10. The inner lower tooth 12 and the inner upper tooth 13 are arranged in parallel. An upper gear 11 is fixedly installed on the end of the upper threaded rod 6 close to the gear ring 10, and the upper gear 11 is meshed with the outer teeth of the gear ring 10. Two groups of driven gears 14 are rotatably installed on the surface of one end of the soaking cylinder 1 close to the gear ring 10.
