DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0028] The cleaning device for producing lyocell fibers according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 5 As shown, the cleaning device for lyocell fiber production of the embodiment of the present application comprises a base 1, a fixing frame 2 and a cleaning assembly 3, wherein the fixing frame 2 is mounted on the base 1. The cleaning assembly 3 comprises a liquid changing mechanism 31, a first electric telescopic rod 32, a connecting frame 33, a placing shell 34, a plurality of connecting holes 35 and a squeezing mechanism 36, wherein the liquid changing mechanism 31 is rotatably arranged on the fixing frame 2.

[0030] It should be noted that the multiple connecting holes 35 can allow external cleaning liquid to quickly enter the placement shell 34 when the placement shell 34 moves down, and when the placement shell 34 is moved out of the cleaning liquid, the multiple connecting holes 35 can quickly discharge the cleaning liquid inside the placement shell 34.

[0031] The first electric telescopic rod 32 is installed on the fixed frame 2, and the output end of the first electric telescopic rod 32 is slidably connected to the fixed frame 2, the connecting frame 33 is installed on the output end of the first electric telescopic rod 32, the placement shell 34 is installed on the connecting frame 33, and the placement shell 34 is located above the liquid exchange mechanism 31.

[0032] It should be noted that in the initial state, the first electric telescopic rod 32 is in a retracted state, and at this time, driven by the first electric telescopic rod 32 , the placement shell 34 is not connected to the liquid exchange mechanism 31 .

[0033] A plurality of communication holes 35 are formed through the bottom surface of the placement shell 34 , and the pressing mechanism 36 is disposed on the connecting frame 33 .

[0034] Specifically, during actual use, the lyocell fiber raw material needs to be cleaned to ensure the quality of the lyocell fiber.

[0035] When the lyocell fiber raw material needs to be cleaned, the lyocell fiber raw material to be cleaned is first spread flat in the placement shell 34. After spreading, the placement shell 34 is driven downward by the output end of the first electric telescopic rod 32 to allow the placement shell 34 to enter the liquid in the liquid changing mechanism 31. Then, the squeezing mechanism 36 is used to squeeze the lyocell fiber raw material, thereby achieving the purpose of cleaning the lyocell fiber raw material.

[0036] In one embodiment of the present application, Figure 2 As shown, the liquid exchange mechanism 31 includes a rotating disk 311, a driving mechanism 312, a plurality of rotating rods 313, a plurality of liquid storage tanks 314 and a plurality of cleaning mechanisms 315, wherein the rotating disk 311 is rotatably disposed on the fixed frame 2.

[0037] It should be noted that the driving mechanism 312 adopts a stepping motor, so that each time the driving mechanism 312 drives the rotating disk 311 to rotate at the same angle, and after the driving mechanism 312 drives the rotating disk 311 to rotate, there is always a liquid storage tank 314 located below the placement shell 34, so that the placement shell 34 can enter the liquid storage tank 314 under the drive of the first electric telescopic rod 32.

[0038] The driving mechanism 312 is mounted on the fixing frame 2, and the output end of the driving mechanism 312 is connected to the rotating disk 311. A plurality of rotating rods 313 are arranged in a circular array on the rotating disk 311. A plurality of liquid storage tanks 314 are rotatably arranged on one end of the corresponding rotating rods 313, and the rotating rods 313 are located on one side of the top of the liquid storage tanks 314.

[0039] It should be noted that the multiple liquid storage tanks 314 can be filled with different cleaning liquids according to cleaning requirements to meet different cleaning requirements, and the amount of cleaning liquid inside the liquid storage tank 314 is two-thirds of the volume of the liquid storage tank 314.

[0040] A plurality of cleaning mechanisms 315 are disposed on corresponding liquid storage tanks 314 .

[0041] Specifically, in actual use, different cleaning liquids need to be replaced according to cleaning needs.

[0042] When the lyocell fiber raw material is cleaned as mentioned above, the first electric telescopic rod 32 needs to drive the placement shell 34 containing the lyocell fiber raw material to move into the liquid storage tank 314, so that when the liquid needs to be replaced, the first electric telescopic rod 32 drives the placement shell 34 to move upward, and then the placement shell 34 is moved out from the inside of the liquid storage tank 314.

[0043] After the liquid storage tank 314 is moved out from the interior of the placement shell 34, the driving mechanism 312 drives the rotating disk 311 to rotate. The rotation of the rotating disk 311 drives multiple liquid storage tanks 314 to rotate, so that the liquid storage tanks 314 filled with different cleaning liquids can be rotated to the bottom of the placement shell 34, and then the placement shell 34 is moved in conjunction with the first electric telescopic rod 32, so that the raw materials of the lyocell fiber can be cleaned.

[0044] In one embodiment of the present application, Figure 2 As shown, the diameter of the liquid storage tank 314 is larger than the diameter of the placement shell 34.

[0045] It should be noted that the caliber of the liquid storage tank 314 is slightly larger than the caliber of the placement shell 34. The purpose is to allow the placement shell 34 to enter the liquid storage tank 314. When the placement shell 34 is moved out from the inside of the liquid storage tank 314, it needs to stay for a short time so that the cleaning liquid inside the placement shell 34 can drip into the corresponding liquid storage tank 314, and multiple liquid storage tanks 314 are filled with different cleaning liquids to meet different cleaning requirements.

[0046] In one embodiment of the present application, Figure 2 As shown, the cleaning mechanism 315 includes a sliding rod 3151 , a sliding plate 3152 , a push spring 3153 and a filter plate 3154 , wherein the sliding rod 3151 slides through the liquid storage tank 314 .

[0047] It should be noted that when the placement shell 34 is located inside a liquid storage tank 314, there is a certain length between the remaining two liquid storage tanks 314 and the base 1, and the length of the sliding rod 3151 is from the top surface of the base 1 to the top surfaces of the remaining two liquid storage tanks 314, so that when the lyocell fiber raw material in one liquid storage tank 314 is cleaned, the sliding rod 3151 drives the filter plate 3154 to move out of the liquid storage tank 314, and then the foreign matter filtered on the surface of the filter plate 3154 can be cleaned.

[0048] The sliding plate 3152 is mounted on one end of the sliding rod 3151, and the sliding plate 3152 is located below the liquid storage tank 314. The pushing spring 3153 is sleeved on the sliding rod 3151, and the pushing spring 3153 is located between the sliding plate 3152 and the liquid storage tank 314. The filter plate 3154 is mounted on the top of the sliding rod 3151, and the filter plate 3154 is slidably arranged in the liquid storage tank 314.

[0049] Specifically, in actual use, during the cleaning process of the lyocell fiber raw material, some impurities will fall into the liquid storage tank 314 and need to be cleaned.

[0050] After one liquid storage tank 314 cleans the lyocell fiber raw material, it is necessary to replace another liquid storage tank 314 to continue cleaning the lyocell fiber raw material. When the liquid storage tank 314 is replaced, the liquid storage tank 314 after cleaning the lyocell fiber raw material will rotate downward. The downward rotation of the liquid storage tank 314 will drive the sliding rod 3151 and the sliding plate 3152 to rotate downward. After the sliding plate 3152 contacts the base 1, the sliding plate 3152 is limited by the base 1, so that when the liquid storage tank 314 continues to rotate downward, the sliding plate 3152 will only follow the rotation but cannot continue to move downward, thereby causing the filter plate 3154 in the liquid storage tank 314 to move upward with the liquid storage tank 314 as a reference, and filtering the impurities inside the liquid storage tank 314 during the upward movement. Finally, the filter plate 3154 is at the top of the liquid storage tank 314, and then the filter on the filter plate 3154 can be cleaned by using an external scraper.

[0051] In one embodiment of the present application, Figure 1 As shown, a plurality of moving rods (not shown in the figure) are rotatably arranged on the bottom surface of the sliding plate 3152.

[0052] It should be noted that the multiple moving rods on the bottom surface of the sliding plate 3152 can reduce the friction of the contact surface when the sliding plate 3152 contacts the base 1, thereby reducing the movement resistance of the sliding plate 3152.

[0053] In one embodiment of the present application, Figure 4 As shown, the extrusion mechanism 36 includes a driving rod 361, a moving block 362, a second electric telescopic rod 363, a contraction cylinder 364, a contraction rod 365, a contraction spring 366, a pressing roller 367 and a driving member 368, wherein the driving rod 361 is rotatably arranged on the connecting frame 33.

[0054] It should be noted that the driving member 368 adopts a driving motor, and the driving motor can rotate forward and reverse, so as to drive the moving block 362 to move left and right.

[0055] The moving block 362 is threadedly connected to the driving rod 361 , and the moving block 362 is slidably connected to the connecting frame 33 , and the second electric telescopic rod 363 is installed on the bottom surface of the moving block 362 .

[0056] It is understandable that the moving block 362 is restricted by the connecting frame 33 , and thus when the driving rod 361 rotates, the moving block 362 will not rotate synchronously with the driving rod 361 .

[0057] The contraction tube 364 is installed on the output end of the second electric telescopic rod 363 , and the contraction rod 365 is slidably arranged in the contraction tube 364 . The contraction spring 366 is arranged in the contraction tube 364 , and one end of the contraction spring 366 is connected to the contraction rod 365 .

[0058] It should be noted that there are scales engraved on the surface of the contraction rod 365, and the scales can intuitively show the contracted length of the contraction rod 365. Since the contracted length of the contraction rod 365 is the same as the contracted length of the contraction spring 366, and the contracted length of the contraction spring 366 is related to the elasticity of the contraction spring 366, the elasticity of the contraction spring 366 can be judged by the contracted length of the contraction rod 365.

[0059] The pressing roller 367 is disposed below the contraction rod 365. The driving member 368 is mounted on the connecting frame 33, and the rotating shaft of the driving member 368 is connected to one end of the driving rod 361.

[0060] Specifically, in actual use, the lyocell fiber raw material needs to be squeezed to achieve the purpose of cleaning the lyocell fiber raw material.

[0061] When the lyocell fiber raw material needs to be cleaned, the lyocell fiber raw material is first placed in the placement shell 34, and then the placement shell 34 is driven by the first electric telescopic rod 32 to enter the liquid storage tank 314. After the placement shell 34 containing the lyocell fiber raw material enters the liquid storage tank 314, the second electric telescopic rod 363 drives the shrinking cylinder 364 and the shrinking rod 365 to move downward. The downward movement of the shrinking rod 365 drives the pressing roller 367 to move downward, and then the pressing roller 367 contacts the lyocell fiber raw material. After the contact, the driving member 368 drives the driving rod 361 rotates, and since the moving block 362 is threadedly connected to the driving rod 361, the moving block 362 will be driven to move when the driving rod 361 rotates, and the movement of the moving block 362 will drive the shrinking cylinder 364 and the shrinking rod 365 to move, and then the pressing roller 367 can be driven to squeeze the lyocell fiber raw material, so as to achieve the purpose of cleaning the lyocell fiber raw material, and the height of the output end of the second electric telescopic rod 363 can be controlled to descend, and the squeezing force of the pressing roller 367 on the lyocell fiber raw material can be adjusted as needed.

[0062] In one embodiment of the present application, Figure 4 As shown, the pressing roller 367 is connected to the contraction rod 365 through a U-shaped frame, and the pressing roller 367 is rotatably connected to the U-shaped frame.

[0063] In summary, the cleaning device for the production of lyocell fibers in the embodiment of the present application utilizes a placement shell 34 that moves up and down in cooperation with a rotating liquid storage tank 314, so that the lyocell fibers in the placement shell 34 can be quickly placed in different cleaning liquids, thereby improving the efficiency of cleaning the lyocell fibers. At the same time, the squeezing mechanism 36 can be used to squeeze the lyocell fibers during cleaning, thereby improving the cleaning effect of the lyocell fibers. At the same time, the squeezing mechanism 36 can also reduce the content of the cleaning liquid in the lyocell fibers when the lyocell fibers are taken out, thereby preventing the cleaning liquid from dripping everywhere and causing waste of the cleaning liquid.
