Description

Technical Field

[0001] The invention belongs to the technical field of nonwoven product production machinery, and in particular relates to a cotton feeding device for a needle loom. Background Art

[0002] The aforementioned needle-loom feeding device feeds the fiber cotton web to be needled to the needle-loom, and the needle-loom performs needle-punching to obtain the desired non-woven product. As for the complete set of non-woven product production lines, it mainly includes an opener, a carding machine, a web-laying machine, and a needle-loom or a hydroentanglement machine. The carding machine is between the opener and the web-laying machine. The carding machine combs the non-woven fibers opened by the opener and conveys them to the web-laying machine. The web-laying machine lays the non-woven fibers into a cotton web of the required thickness (also called the required gram weight) and then conveys them to the needle-loom or hydroentanglement machine to entangle the fibers to form a non-woven product. Since a needle loom feeding device (also called "feeding device") needs to be installed between the web laying machine and the needle loom, otherwise the cotton web laid out by the web laying machine cannot be directly fed into the needle loom, the needle loom feeding device is an indispensable auxiliary device in a complete set of non-woven product production lines. Specifically, its function and working principle can be fully understood by reading "A needle loom feeding device and its needle loom" recommended by Chinese patent CN204608332U, which is not limited to the examples.

[0003] The cotton feeding device of the needle loom in the prior art uses the same set of power transmission device to drive the upper feeding roller (also called "upper insert roller"), the lower feeding roller (also called "lower insert roller"), the upper feeding curtain and the lower feeding curtain at the same time, so it is impossible to separately adjust the speed of the upper and lower feeding rollers and the upper and lower feeding curtains, resulting in the speed ratio between the upper and lower feeding rollers and the upper and lower feeding curtains being unable to be adjusted. For example, when the speed of the upper and lower feeding curtains is significantly slower than that of the upper and lower feeding rollers, cotton jamming often occurs, causing unexpected drafting or failure to feed cotton. In addition, since the angle between the upper and lower feeding curtains cannot be adjusted, when the cotton web layers laid out by the web laying machine are different due to different fibers and / or different gram weights of the non-woven products to be produced, the process requirements can usually only be met by replacing the transmission wheel, but the work of replacing the transmission wheel such as the sprocket is quite troublesome. In view of the above factors, it is necessary to make improvements, and the technical solution to be introduced below is produced under this background. Summary of the invention

[0030] When the needle loom or the cotton feeding device of the needle loom of the present invention needs to be cleaned, maintained and / or repaired, the cotton feeding device of the needle loom of the present invention needs to be moved away from the feeding device. Figure 7The needling machine 10 shown in the figure has a directional displacement. In this case, it is necessary for the check-in personnel or the equipment maintenance personnel (usually two people work together to synchronously operate the left and right wall panel front and back displacement operating mechanisms 112 and 122) to operate the left and right wall panel front and back displacement operating mechanisms 112 and 122. Since the structure and the action mechanism, that is, the action principle, of the right wall panel front and back displacement operating mechanism 122 are the same as those of the left wall panel front and back displacement operating mechanism 112, the applicant will only explain the left wall panel front and back displacement operating mechanism 112 below. The operator rotates the left wall panel forward and backward displacement operating hand wheel 1124 in the counterclockwise direction, which drives the left wall panel forward and backward displacement operating hand wheel shaft 11241 to rotate, and at the same time, the left base rack meshing gear 1123 is driven by the left wall panel forward and backward displacement operating hand wheel shaft 11241. Since the left base rack meshing gear 1123 is meshed with the left base rack teeth 1321 of the left base rack 132, the left base rack meshing gear 1123 moves backward along the left base rack 132. At the same time, the aforementioned left wall panel roller 1111 rolls backward along the left base guide bar 131, so that the left wall panel 11 and the components arranged with the left wall panel 11 as a carrier are also displaced as the left wall panel 11 is displaced backward, so that the present invention leaves the needling machine 10, and vice versa. The applicant needs to reiterate that: while an operator operates the left wall panel forward and backward displacement operating mechanism 112, another operator synchronously operates the right wall panel forward and backward displacement operating mechanism 122, that is, the forward and backward displacements of the left and right wall panels 11, 12 are in step with each other.

[0031] See also Figure 2 , Figure 3 And continue to combine Figure 1Since the structure of the lower feeding curtain rear adjustment mechanism 7 is the same as that of the lower feeding curtain front adjustment mechanism 6, the applicant only describes the structure of the lower feeding curtain front adjustment mechanism 6 in detail. The lower feeding curtain front adjustment mechanism 6 includes a lower feeding curtain front lifting side plate 61, a lower feeding curtain front lifting seat 62, a lower feeding curtain front lifting operation hand wheel 63, a lower feeding curtain front lifting operation hand wheel driving worm 64, and a lower feeding curtain front lifting worm wheel 65. The upper part of the lower feeding curtain front lifting worm gear cooperates with the screw 66, and the upper part of the lower feeding curtain front lifting side plate 61 is hinged with the left end of the lower feeding curtain front lifting side plate hinge shaft head 611, and the right end of the lower feeding curtain front lifting side plate hinge shaft head 611 is fixed with the lower feeding curtain front lifting side plate hinge shaft head fixing plate 6111, and the lower feeding curtain front lifting side plate hinge shaft head fixing plate 6111 is fixed with the left side surface of the left supporting arm 521 of the aforementioned lower feeding curtain driven roller through a group of fixing plate screws. The lower part of the curtain front lifting side plate 61 protrudes from the lower surface of the left supporting arm 521 of the lower feeding curtain driven roller, the lower feeding curtain front lifting seat 62 is fixed to the lower part of the lower feeding curtain front lifting side plate 61 through the lower feeding curtain front lifting seat fixing plate 621 and the lifting seat fixing plate screw 6211, and the lower feeding curtain front lifting operation hand wheel 63 is fixed to the left end of the lower feeding curtain front lifting operation hand wheel driving worm 64, and the lower feeding curtain front lifting operation hand wheel driving worm 64 is driven by a pair of driving worm bearings 641 ( Figure 3 The lower feeding curtain front lifting seat 62 is rotatably supported by the lower feeding curtain front lifting seat 62, and a worm screw thread 642 is formed at the middle part of the lower feeding curtain front lifting operation hand wheel driving worm 64 and at a position corresponding to the lower feeding curtain front lifting worm wheel 65. The worm screw thread 642 is connected to the worm wheel outer thread ( Figure 3 The worm wheel inner thread hole at the central position of the lower feed curtain front lifting worm wheel 65 is threadedly engaged with the lower feed curtain front lifting worm wheel matching screw 66. The lower end of the lower feed curtain front lifting worm wheel matching screw 66 forms a lower feed curtain front lifting worm wheel matching screw hinge joint 661.

[0033] When the fiber material used to produce non-woven products changes and / or the grammage of the cotton web layer laid out by the aforementioned web laying machine changes, the opening size between the lower feeding curtain 5 and the upper feeding curtain 4 must be adjusted according to the process requirements, that is, the angle between the lower feeding curtain 5 and the upper feeding curtain 4 needs to be adjusted. Specifically, the lower feeding curtain 5 is adjusted to meet the opening size requirement between the upper and lower feeding curtains 4, 5. The adjustment process is: the operator rotates the lower feed curtain front lifting operation hand wheel 63, and the lower feed curtain front lifting operation hand wheel 63 drives the lower feed curtain front lifting operation hand wheel to drive the worm 64, and the lower feed curtain front lifting operation hand wheel drives the worm 64 to drive the lower feed curtain front lifting worm wheel 65. Since the lower feed curtain front lifting worm wheel 65 and the lower feed curtain front lifting worm wheel matching screw 66 are threadedly matched, the lower feed curtain front lifting seat 62 causes the rear end of the lower feed curtain driven roller left support arm 521 to move upward through the lower feed curtain front lifting side plate 61, and vice versa, that is, the lower feed curtain front lifting operation hand wheel 63 is reversely operated, and the rear end of the lower feed curtain driven roller left support arm 521 is moved downward in the opposite transmission mode to the above. The applicant needs to explain that: while adjusting the lower feed curtain front adjustment mechanism 6, another operator simultaneously performs corresponding operations on the lower feed curtain rear adjustment mechanism 7. That is to say, the adjustment of the front and rear adjustment mechanisms 6, 7 of the lower feeding curtain is synchronous and carried out simultaneously.
