[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] See also Figure 1-Figure 4The bamboo chip softening equipment for producing bamboo fiber shown in the figure includes a cylinder 1, a placement component, a steam softening component and an opening and closing component. A take-in and put-out port 2 is opened on one side of the cylinder 1. The placement component is installed inside the cylinder 1 to place the bamboo chips that need to be soaked separately. The steam softening component is installed below the cylinder 1 to transport steam into the cylinder 1 to heat the bamboo chips placed inside. The opening and closing component is installed on the outside of the cylinder 1 to open or close the take-in and put-out port 2.

[0021] See also Figure 2 and Figure 3 The placement component shown in the figure includes a rotating shaft 3 arranged inside the cylinder 1, both ends of the rotating shaft 3 are rotatably connected to the inner wall of the cylinder 1, and mounting blocks 4 are fixedly sleeved on the outer sides of both ends of the rotating shaft 3, and partition plates 5 are fixedly provided on the outer walls of the mounting blocks 4 at equal distances. One end of the rotating shaft 3 passes through one end of the cylinder 1 and extends outward to be fixedly connected to the first gear 6. A second gear 7 is provided on the lower side of the first gear 6. The first gear 6 and the second gear 7 are meshed and connected by a tooth chain 8, and one side of the second gear 7 is connected to the output end of the motor 9.

[0022] See also Figure 1 , Figure 2 and Figure 4 The steam softening assembly shown in the figure includes a heating box 10, a heating pipe 11 is fixedly installed inside the heating box 10, a steam pipe 12 is connected to one side of the heating box 10, and the end of the steam pipe 12 away from the heating box 10 is connected to the top of the cylinder 1, and a water supply pipe 13 with a control valve is connected to one side of the heating box 10.

[0023] When the bamboo chips are softened: first open the opening and closing assembly on the access port 2, and then place the bamboo chips one by one between two adjacent partition plates 5 inside the cylinder 1. The partition plates 5 at both ends of the rotating shaft 3 can separate and place the bamboo chips, avoiding the stacking of the bamboo chips inside the cylinder 1, increasing the separation of the bamboo chips inside the cylinder 1, and increasing the contact area between the bamboo chips and the soaking liquid inside the cylinder 1. After the bamboo chips are placed, the staff will close the opening and closing assembly to seal the access port 2.

[0024] After the bamboo pieces are placed and the access port 2 is sealed, the corresponding soaking method can be selected according to the softening needs. When soaking is needed to soften the bamboo pieces, the soaking liquid is injected into the cylinder 1 through the water injection pipe 19, and then the motor 9 is started. The motor 9 can drive the second gear 7 at the output end to rotate when it is started. The second gear 7 is meshed with the first gear 6 through the toothed chain 8, and the first gear 6 can be driven to rotate through the toothed chain 8. The first gear 6 is fixedly installed on the rotating shaft 3, which can drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 can drive the partition plate 5 to rotate, and then drive the bamboo pieces placed between the partition plates 5 to rotate inside the cylinder 1, so that the bamboo pieces are fully contacted with the soaking liquid inside the cylinder 1. At the same time, when the bamboo pieces rotate inside the cylinder 1, they can stir the soaking agent in the soaking liquid, so that the soaking agent is better mixed in the soaking liquid, which can effectively improve the efficiency of bamboo soaking and softening. At this time, the bamboo pieces can be softened and processed using the soaking liquid.

[0025] When the bamboo chips need to be softened by steam, the staff will discharge the soaking liquid inside the cylinder 1 through the drain pipe 20, and then close the control valves on the water injection pipe 19 and the drain pipe 20, and then energize the heating tube 11 inside the heating box 10. The energization of the heating tube 11 can heat the water inside the heating box 10, and the heated water generates water vapor, which will flow into the cylinder 1 through the steam pipe 12. After the hot steam enters the cylinder 1, it can steam heat and soften the bamboo chips placed inside the cylinder 1, which can effectively improve the softening efficiency of the bamboo chips. At the same time, the motor 9 is started to drive the bamboo chips between the partition plates 5 to rotate inside the cylinder 1, which can achieve uniform heating of the bamboo chips by hot steam, which can effectively improve the working efficiency of bamboo chip softening. The device can achieve selective steam softening and soaking softening of bamboo chips inside the same cylinder 1, avoiding the use of multiple equipment, and effectively reducing the cost investment.
