Cotton feeding device with improved structure for carding machine

Abstract

The invention discloses a cotton feeding device with an improved structure for a carding machine, and belongs to the technical field of non-textile machinery. The carding machine comprises a carding machine frame, a cotton opening roller and a cotton uniformizing roller; the cotton feeding device comprises a cotton feeding roller, a cotton feeding roller cover, a cotton pressing roller, a pair of cotton feeding roller cover adjusting mechanisms and a transitional transmission shaft; the cotton feeding roller is supported on a cotton feeding roller supporting wall plate; the cotton feeding roller cover is correspondingly arranged above the cotton feeding roller; the cotton pressing roller is supported on the cotton feeding roller cover; the pair of the cotton feeding roller cover adjusting mechanisms is arranged on the carding machine frame; the transitional transmission shaft is connected with the pair of the cotton feeding roller cover adjusting mechanisms; the cotton feeding device is characterized in that a cotton feeding roller cover strengthening web plate is arranged in the length direction of the cotton feeding roller cover; a tensioning wheel seat is fixed to an end surface enclosing plate of the cotton feeding roller cover and corresponds to the right side of a guide rail seat; a tensioning wheel is rotatably arranged on the tensioning wheel seat. The adjustment time is shortened; the work efficiency of the carding machine is improved; the overall adjustment effect of the cotton feeding roller cover is ensured; the work intensity is reduced; the influence on the cotton feeding effect caused by generating deflection is avoided; the structure is simplified; the movement effect of a transmission chain of the cotton feeding roller is ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a cotton feeding device of a carding machine with improved structure. Background technique [0002] The cotton feeding device of the aforementioned carding machine is also called the cotton feeding device of the carding machine. As known in the industry, the production equipment of complete sets of non-woven products (such as non-woven fabrics and non-woven felts) mainly includes opening machines, carding machines, web-laying machines and Needle punching machine or spunlace machine, the carding machine is between the opener and the web-laying machine, the carding machine combs the non-woven fibers loosened by the opener and transports them to the web-laying machine, and the web-laying machine lays them After forming a cotton web of required thickness, it is sent to a needle punching machine or a spunlace machine to entangle and slash the fibers to form a n...

Problems solved by technology

But because a pair of cotton-feeding roller cover adjustment mechanisms 5 are respectively located at the two sides of the carding machine frame 1 and are independent from each other, so the worker adjustment needs to operate the two cotton-feeding roller cover adjustment mechanisms 5 respectively, thereby producing the following technology Problems: First, since the two feeding roller cover adjustment mechanisms 5 are operated separately, the adjustment time for the cotton feeding roller cover 3 is lengthy, which affects the working efficiency of the carding machine, because the adjustment is carried out when the carding machine is in a shutdown state Moreover, during the period of adjustment, the opener, web lapper and even the needling machine are all in a shutdown state; secondly, since the two cotton feeding roller cover adjustment mechanisms 5 are operated separately, it is difficult to ensure that the entire cotton feeding roller The level of the cover 3, once there is even a slight inclination in which one end is high and the other end is low, the uniformity of the cotton feeding amount of the cotton feeding roller 2 will be affected, that is, the amount of cotton feeding will be more or less or more. This rare phenomenon, the current solution is to repeatedly fine-tune the cotton feeding roller cover adjustment mechanism 5 by workers; third, because the aforementioned adjustment operation belongs to two-sided operations, that is, two operations, the work intensity of the workers is relatively large, and the adjustment effect is also affected. The influence of factors such as workers' experience, sense of responsibility, and emotions

[0007] the above by image 3 The technical problems caused by the shown structure are remedied by the "Cotton Feeding Device of Carding Machine" recommended by Chinese Patent Application Publication No. CN104499115A, but this CN104499115A still has the following two shortcomings: First, because the length of the cotton feeding roller cover is different from that of the feeding roller cover. Cotton rollers are compatible, and because the larger the size of the non-woven product to be processed (that is, the larger the door width), the longer the cotton feeding roller, the same as the cotton feeding roller cover, so the lengthy cotton feeding roller cover is easy to appear The deflection affects the cotton feeding effect of the cotton feeding device; secondly, due to the actual working process, the cotton feeding roller, cotton opening roller, cotton pressing roller and the lower part corresponding to the length direction between the cotton feeding roller and the cotton opening roller That is to say, the three cotton equalizing rollers corresponding to the bottom of the aforementioned triangular area form a synchronous transmission system, so the transmission belt (usually the transmission chain) is relatively long, so in order to ensure the transmission effect of the transmission belt, corresponding expansion gears are set on the frame. The tensioner seat, on which the tensioner wheel is rotatably set, the tensioner wheel is in contact with the transmission belt

Setting the tensioner pulley directly on the frame can make the transmission belt obtain the desired tensioning effect, but it makes the structure of the frame complex and difficult to manufacture, and it is uneconomical
