Description

Technical Field:

[0001] The present invention relates to the technical field of textile production and processing equipment, and more specifically to a degumming device for flax fibers used in textile production. Background Art:

[0002] In the current production process of textile flax fibers, degumming treatment is required to separate the fibers from the biological gum. Currently, composite bioenzymes are commonly used for fermentation degumming. Its operating conditions are mild, the damage to the fibers is small, it is easy to control the degree of degumming during production, which is beneficial to improving the fiber yield, and it consumes less water and causes less pollution.

[0003] Currently, in bioenzyme degumming treatment, most of the flax raw materials are directly soaked in the bioenzyme solution. During the degumming process, the bioenzyme ferments and dissolves the outer biological gum. However, the existing flax raw materials are placed in the solution, and there is more bioenzyme liquid in contact with their exterior, while the raw materials inside or in the middle are not in much contact, thus affecting the degumming efficiency. Summary of the Invention:

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a degumming device for flax fibers used in textile production, which can move the placed flax fiber raw materials and fill the liquid in the middle part, thereby increasing the repeated contact with the liquid containing bioenzyme and improving the degumming uniformity and efficiency.

[0059] When this embodiment is in use, the liquid inlet ends (the liquid inlet ends are at the right ends, not shown in the drawings) of the upper main liquid inlet connecting pipe 41 and the lower main liquid inlet connecting pipe 42 are connected to an external biological enzyme liquid delivery tank through a connecting pipe, and the biological enzyme liquid is introduced into the upper main liquid inlet connecting pipe 41 and the lower main liquid inlet connecting pipe 42;

[0060] When in use, first open the side connection cover plate 191, and then open the cover plate 22, then the linen fibers to be degummed can be placed into the inner feeding housing 20. Then, fix and close the cover plate 22 and the side connection cover plate 191. Then, the biological enzyme liquid is sprayed onto the linen fibers from the small-diameter hole section of the central stepped through hole 151 of the upper flushing lifting column 15 and the lower flushing lifting column 14. Then, by operating all the intermediate running motors and the running motors, the intermediate rotating disk 123 and the second intermediate rotating disk 183 rotate, causing the upper lifting plate 12 and the lower lifting plate 13 to move up and down, so that the upper flushing lifting column 15 and the lower flushing lifting column 14 move up and down, squeezing the linen fibers in the inner feeding housing 20, thereby ensuring that the biological enzyme liquid can fully enter the interior of the linen fibers and making the biological enzyme liquid evenly distributed on the linen fibers. At the same time, during operation, for example, after running for 5 minutes generally, by operating the intermediate running motors and the running motors, the sensing end of the proximity switch 4 approaches the top of the corresponding sensing part 2 to achieve sensing. At this time, the intermediate running motors and the running motors stop running (the intermediate running motors and the running motors in this embodiment are servo motors, so as to ensure that when they stop running, the intermediate rotating disk 123 and the second intermediate rotating disk 183 will no longer rotate). At this time, the upper flushing lifting column 15 and the lower flushing lifting column 14 will not extend into the corresponding through holes of the inner feeding housing 20;

[0061] Then, by pushing and retracting the push rods of all the lateral movement pushing oil cylinders 16, lateral back-and-forth movement is achieved, causing the inner feeding housing 20 to move left and right, making the linen fibers inside it move left and right (the linen fibers placed in the inner feeding housing 20 cannot be completely filled), so that the inner linen fibers shake to ensure uniform mixing;

[0062] Then, when the push rods of all the lateral movement pushing oil cylinders 16 return to the initial position, at this time, by operating all the intermediate running motors and the running motors, the up-and-down squeezing operation is carried out again to make the mixing uniform and improve the efficiency and effect of biological enzyme degumming.

[0063] In the inner feeding housing 20 of this embodiment, its rear wall plate is a movable wall plate, its top surface and bottom surface are pressed against the top surface of the top plate of the inner feeding housing 20 and the top surface of the bottom plate, the left and right side walls of the rear wall plate are closely attached to the inner side walls of the corresponding left side plate and right side plate. At the same time, a horizontally extending moving block 29 is fixed in the middle of the rear wall surface of the rear wall plate of the main box body 10. A rear pushing oil cylinder 70 is fixed in the middle of the rear wall surface of the rear wall plate of the main box body 10. The end of the push rod of the rear pushing oil cylinder 70 extends out of the inner wall surface of the rear wall plate of the main box body 10 and is fixed with a pushing block 71. Upper and lower extending parts are formed on the front wall surface of the pushing block 71, and guiding parts are formed on the opposite wall surfaces of the two extending parts. Horizontally extending guide grooves are formed on the top surface and bottom surface of the moving block 29, and the guiding parts are inserted into the corresponding guide grooves.

[0064] When performing the liquid treatment of bio - enzymes, some impurities such as particulate matter in the flax fibers of the inner discharging housing 20 will be in the liquid, and some of them will fall with the liquid into the receiving tray 32 for accumulation.

[0065] And a drainage connection screw - through hole is formed in the middle of the lower part of the right - hand side plate of the main housing 10. When in use, the plug 6 needs to be removed and a drain pipe is connected. The end of the drain pipe is connected to a control valve, which can be opened through the control valve to achieve liquid drainage when liquid drainage is required.

[0066] In this embodiment, after the bio - enzyme liquid is filled to a certain amount, the liquid filling needs to be stopped. After the reaction is completed, the control valve is opened to achieve liquid drainage, which is determined according to the operation conditions.

[0067] After this embodiment is completed, by opening the side connection cover plate 191 and the covering plate 22, and being pushed by the push rod of the rear - feeding oil cylinder 70, the rear wall plate of the inner discharging housing 20 is pushed forward (the pushing speed is slow), and the flax fibers in the inner discharging housing 20 are pushed forward. When pushing, the flax fibers are pushed out from the central inlet - outlet 21 of the inner discharging housing 20. When pushing out, manual material receiving and taking away are required. Among them, it is pushed at most to the middle of the inner discharging housing 20 (since the width of the rear wall plate is greater than that of the central inlet - outlet 21, when pushing, the redundant flax fibers on the left and right sides are squeezed towards the middle and can be taken out), and the remaining flax fibers can be taken out manually.
