Description

Technical Field

[0002] Bamboo strips are the main raw material for weaving bamboo products. Bamboo strips are made by splitting bamboo strips. When weaving bamboo products, the bamboo strips need to be bent and woven back and forth, so the bamboo strips need to have strong toughness, and the better the toughness of the bamboo strips, the higher the quality of the woven bamboo products. In order to improve the toughness of the bamboo strips, the bamboo strips are usually placed in lime water for a period of time before splitting, which can effectively improve the toughness of the bamboo strips. However, the existing soaking method usually directly puts a bundle of bamboo strips into a pool for static soaking. During the soaking, the bamboo strips located inside are difficult to contact with the lime water, resulting in poor soaking effect of the internal bamboo strips.

[0040] The disengagement mechanism includes a first driving ring 14 and a second driving ring 15, the first driving ring 14 is fixedly connected to a plurality of second sliding rods 11 corresponding to the plurality of first sliding rods 8 on the cylinder cover 3; the second driving rod 4 is fixedly connected to a plurality of second sliding rods 11 corresponding to the plurality of first sliding rods 8 on the soaking cylinder 2; the first driving ring 14 and the second driving ring 15 are both fixedly connected to a first push rod 16; a first fixing ring 17 is provided at a position close to one side of the soaking cylinder 2 for the two first push rods 16, and support frames 18 are symmetrically provided at the front and rear sides of the first fixing ring 17, the first fixing ring 17 is slidably connected to the support frames 18 on the front and rear sides, and the support frames 18 on the front and rear sides are fixedly connected to the base 1; a clamping mechanism is provided on the side of the fixing frame 10 away from the soaking cylinder 2, and the clamping mechanism is used to clamp the first driving ring 14 and the second driving ring 15 after the first fixing ring 17 pushes the first driving ring 14 and the second driving ring 15 to move to the maximum distance;

[0041] The clamping mechanism includes a second fixed ring 19, which is slidably connected to the support frames 18 on the front and rear sides, and a first rotating ring 20 is rotatably connected inside the second fixed ring 19, a rotating frame 21 is provided inside the first rotating ring, the rotating frame 21 is fixedly connected to the driving rod 4, and a second rotating ring 22 is fixedly connected to the rotating frame 21; the first rotating ring 20 is slidably connected to the rotating frame 21, and a third spring 23 is provided between the first rotating ring 20 and the second rotating ring 22, one end of the third spring 23 is fixedly connected to the first rotating ring 20 and the other end is fixedly connected to the second rotating ring 22; a connecting mechanism is provided on the second rotating ring 22, and the connecting mechanism is used to clamp the first driving ring 14 and the second driving ring 15, and when the first rotating ring 20 moves close to the second rotating ring 22, the second driving ring 15 and the first driving ring 14 are released successively;

[0042] The connecting mechanism includes two fixed frames 24, which are symmetrically distributed at the upper and lower sides of the second rotating ring 22 and are fixedly connected to the second rotating ring 22; the fixed frames 24 are symmetrically slidably connected with clamping plates 25 at the front and rear sides; the first rotating ring 20 is fixedly connected with a first push block 26 located near the fixed frame 24, and two connecting rods 27 are rotatably connected to the first push block 26, and the two connecting rods 27 are rotatably connected to the two clamping plates 25 at one end close to the second rotating ring 22; the upper and lower fixed frames 24 are respectively provided with a first clamping block 28 and a second clamping block 29 on one side close to the soaking cylinder 2, and the width of the first clamping block 28 is greater than the width of the second clamping block 29;

[0043] During operation, when lime water is injected into the soaking cylinder 2, since the multiple drainage holes 6 on the soaking cylinder 2 are blocked by the sealing plate 7 and the sealing plate 7 maintains the sealing of the drainage holes 6 under the action of the limiting plate 12 and the first sliding rod 8, it can be well ensured that the soaking cylinder 2 will not leak lime water; when the bamboo strips are soaked, the first fixing ring 17 is driven to move away from the soaking cylinder 2. When the first fixing ring 17 moves, the first driving ring 14 and the second driving ring 15 are pushed to move by the first push rod 16 on the first driving ring 14 and the second driving ring 15 at the same time, and the first driving ring 14 drives the multiple second sliding rods 11 and the multiple limiting plates 12 connected thereto to move , multiple limiting plates 12 and multiple first slide bars 8 corresponding to multiple sealing plates 7 on the cylinder cover 3 gradually disengage; the second driving ring 15 drives the multiple second slide bars 11 and multiple limiting plates 12 connected thereto to move, and multiple limiting rods and multiple first slide bars 8 corresponding to multiple sealing plates 7 on the soaking cylinder 2 gradually disengage; when the first driving ring 14 and the second driving ring 15 move, the first driving ring 14 and the second driving ring 15 respectively drive the first clamping block 28 and the second clamping block 29 to move, and when the limiting rod moves to a position completely disengaged from the first slide bar 8, at this time, the first clamping block 28 and the second clamping block 29 are just clamped by the clamping plates 25 at two positions on the second rotating ring 22;

[0044] When the first clamping block 28 and the second clamping block 29 are clamped by the two clamping plates 25 on the second rotating ring 22, all the limit plates 12 remain in a state of being disengaged from the first sliding rod 8. At this time, the driving motor 5 accelerates the rotation speed of the soaking cylinder 2. When the soaking cylinder 2 rotates rapidly, the sealing plate 7 on the soaking cylinder 2 and the cylinder cover 3 will be thrown away, and the sealing plate 7 on the soaking cylinder 2 and the cylinder cover 3 will be separated from the soaking cylinder 2 and the drainage hole 6 on the cylinder cover 3. At this time, the lime water in the soaking cylinder 2 will be automatically discharged through the drainage hole 6; after the lime water in the soaking cylinder 2 is discharged, since the soaking cylinder 2 maintains a relatively high rotation speed, the lime water remaining on the bamboo strips and in the gaps of the bamboo strips can be quickly dried under the action of centrifugal force;

[0045] When the bamboo strips in the soaking cylinder 2 are spun dry, the second fixed ring 19 is driven to move toward the soaking cylinder 2. When the second fixed ring 19 moves, it will drive the first rotating ring 20 to move. The first rotating ring 20 will drive the two first pushing blocks 26 connected thereto to move. When the first pushing blocks 26 move, they push the two clamping plates 25 in the fixed frame 24 to move away from each other through the two connecting rods 27 connected thereto. Since the width of the second clamping block 29 is smaller than the first clamping block 28, when the distance between the two clamping plates 25 is greater than the width of the second clamping block 29 and smaller than the width of the first clamping block 28, the second driving ring 15 will automatically reset under the action of the multiple second springs 13 connected thereto, and the multiple limit plates 1 on the second driving ring 15 will automatically reset. 2 is moved again to a position in contact with the first slide bar 8 on the soaking cylinder 2, and the multiple sealing plates 7 on the soaking cylinder 2 again maintain the effect of blocking the drainage hole 6; at this time, the cylinder cover 3 is opened, the bamboo strips after drying are taken out, and then new bamboo strips are put in and new lime water is injected; after the cylinder cover 3 is covered, the second fixing ring 19 is driven again to continue to move in the direction close to the soaking cylinder 2, and the two clamping plates 25 in the fixing frame 24 continue to open. When the two clamping plates 25 are opened to a degree greater than the width of the first clamping block 28, the first driving ring 14 is reset and drives the multiple limiting plates 12 to fit with the first slide bar 8 on the cylinder cover 3, so that the sealing plates 7 on the cylinder cover 3 maintain the effect of blocking the drainage hole 6 on the cylinder cover 3, and then the motor 5 can be started to drive the soaking cylinder 2 to rotate to soak the bamboo strips.

[0046] like Figure 6-8 As shown, as a further solution of the present invention, the protection mechanism includes a protection cover 30, which is located above the base 1 and is slidably connected to the base 1; a first cylinder 31 is fixedly connected to the protection cover 30, and the telescopic end of the first cylinder 31 is fixedly connected to the base 1; a second push block 32 and a third push block 33 are symmetrically fixedly connected to the front and rear sides of the first fixing ring 17 and the second fixing ring 19, respectively, a second push rod 34 is provided above the second push block 32, a telescopic rod 35 is fixedly connected to the second push rod 34, and the telescopic rod 35 is fixedly connected to the protection cover 30; a third push rod 36 is provided above the third push block 33, and the third push rod 36 is fixedly connected to the protection cover 30;

[0047] When the soaking tube 2 is working, lime water will splash everywhere because the soaking tube 2 rotates rapidly. By starting the first cylinder 31, the protective cover 30 is driven to move downward to cover the soaking tube 2. When the protective cover 30 moves downward to a position where it fits with the base 1, the four second push rods 34 on the protective cover 30 will respectively push the four second push blocks 32 to move, and the second push blocks 32 on the left and right sides will respectively drive the first fixing rings 17 on the left and right sides to move left and right respectively; when the soaking tube 2 completes drainage, the first cylinder 31 is started to drive the protective cover 30 to move upward, and the protective cover 30 will drive the four telescopic rods 35 connected thereto to move upward. When the telescopic rods 35 are extended to the maximum extent, the protective cover 30 continues to move upward and will drive the third push rod 36 to move upward through the telescopic rod 35. When the third push rod 36 moves upward, it will push the corresponding third push block 33 to move in the direction close to the soaking tube 2, and the two third push blocks 33 on the left side will drive the second fixing ring 19 on the left side to move right and the two third push blocks 33 on the right side will drive the second fixing ring 19 on the right side to move left.

[0048] like Figure 8-9 As shown, as a further solution of the present invention, a water tank for collecting waste lime water is provided on the base 1 at the bottom of the soaking cylinder 2, and a water leakage net 37 is provided on the top of the water tank;

[0049] During operation, under the protection of the protective cover 30 , the lime water thrown out by the rapid rotation of the soaking tube 2 will eventually flow into the water tank on the base 1 through the water leakage net 37 .

[0050] like Figure 5 As shown, as a further solution of the present invention, the second cylinder 38 is symmetrically rotatably connected to the left and right sides of the soaking cylinder 2, and the telescopic end of the second cylinder 38 is rotatably connected to the cylinder cover 3;

[0051] When working, by simultaneously starting the second cylinders 38 on the left and right sides to extend, the second cylinders 38 on the left and right sides will push the cylinder cover 3 to rotate and open. When the second cylinders 38 on the left and right sides are started to shrink at the same time, the second cylinders 38 on the left and right sides will pull the cylinder cover 3 to rotate and close.
