Description

TECHNICAL FIELD

[0001] The utility model relates to cotton processing machinery technical field, concretely relates to a rib of gin. BACKGROUND

[0002] Gin is an important machine in cotton processing, the bottom of gin gossypium sp. Chamber is arc chamber formed by rib arrangement, the saw blade arranged on the sawtooth roller enters into the arc chamber through the gap between the ribs, the sawtooth roller rotates at high speed, drives the gossypium sp. In gin gossypium sp. Chamber rotates, and the sawtooth on the saw blade that extends into the gossypium sp. Chamber through the gap between the ribs hooks and pulls down the cotton fiber on the gossypium sp., and the cotton fiber is sent into the cotton box by the brush or airflow, and the cottonseed is blocked by the rib, and flows along the rib surface, and the rib of the current gin is usually cast iron material, the inner side and two sides of the rib near the working point are working area, due to the rib at the working point being worn by the cotton fiber passing and the saw blade rubbing for a long time, the quality of cotton processing is affected.

[0003] CN216585324U discloses a durable gin rib, including main fixed end, main fixed hole, working surface, working edge, vice fixed hole and vice fixed end, characterized by: the working point area on the working surface is provided with a dovetail groove, and a corresponding wear-resistant block is arranged in the dovetail groove, which can better fix the wear-resistant block, and the working point of the rib is not easy to wear, the service life of the rib is improved, the quality of cotton processing is improved, the use cost is reduced, and the working efficiency is improved.

[0004] But the step between the fixed end and the working surface of the above structure causes the resistance of the gossypium sp. Roll in the cotton processing process to be large, the speed difference between the saw blade and the cotton roll is large, the cotton fiber is damaged due to the speed difference, and the impurity discharge hole is arranged at the step end face, which is not conducive to impurity discharge. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a gin rib to solve the problem that the resistance of the gossypium sp. Roll in the cotton processing process is large, the speed difference between the saw blade and the cotton roll is large, and the cotton fiber is damaged due to the speed difference.

[0006] In order to achieve the above object, the basic scheme provided by the utility model is as follows: a gin rib, including fixed end, fixed hole, working surface, characterized in that, the fixed end is arranged at the end of the working surface, the fixed end and the working surface are in the same horizontal plane, the working surface is provided with an impurity discharge hole, the impurity discharge hole is composed of two notches, and the notch is arranged between the working surface and the fixed end.

[0007] The rib surface is smooth and has no high and low steps, the resistance of the seed cotton roll in the cotton processing process is reduced, the speed of the cotton roll is accelerated, the speed difference between the saw blade and the cotton roll is reduced, the tensile damage of the cotton fiber caused by the speed difference is reduced, the saw blade has a larger pulling force on the cotton fiber caused by the tight cotton roll, and the damage of the cotton fiber is further reduced.

[0008] Scheme two, which is a preferred embodiment of the basic scheme, the working surface is polished.

[0009] Scheme three, which is a preferred embodiment of the basic scheme, the working surface further comprises a first arc and a second arc, and the back of the working surface is provided with a support ridge.

[0010] Scheme four, which is a preferred embodiment of the basic scheme, the working surface and the support ridge are wide to narrow. BRIEF DESCRIPTION OF DRAWINGS

[0011] Fig. 1 is a structural schematic view of a rib of a cotton gin according to the present application;

[0012] Fig. 2 is a front view of the rib of the cotton gin according to the present application;

[0013] Fig. 3 is a schematic view of the installation of the rib of the cotton gin according to the present application. DETAILED DESCRIPTION

[0014] The present application will be further described in detail through specific embodiments:

[0015] The reference signs in the accompanying drawings of the specification include: 1-fixed end, 2-fixed hole, 3-working surface, 4-groove, 5-support ridge, 6-first arc, 7-second arc, and 8-impurity discharge hole.

[0016] EMBODIMENT

[0017] As Figs. 1 to 3As shown: a rib of a carding machine includes a fixed end 1, a fixed hole 2, a working surface 3, a support ridge 5, the fixed end 1, the working surface 3 and the support ridge are integrally formed, the support ridge 5 is arranged on the back of the working surface 3, the working surface 3 and the support ridge 5 are wide to narrow, the fixed hole 2 is a counter-sunk hole, the fixed end 1 is arranged at the end of the working surface 3, a notch 4 is arranged between the working surface 3 and the fixed end 1, the notches 4 on the two adjacent ribs form a trash hole 8; the surface of the working surface 3 is polished; the working surface 3 further includes a first curved arc 6 and a second curved arc 7.

[0018] The embodiment of the present application is that the ribs are fixed in the carding machine by counter-sunk bolts, and the ribs are installed side by side, when installing, the saw blade is at the position of the second curved arc 7, because the working surface at the second curved arc 7 and the support ridge 5 are relatively narrow, the saw blade will not rub against the rib, the notches 4 of the two adjacent ribs are opposite, forming a trash hole 8, because the fixed end 1 and the working surface 3 are in the same horizontal plane, so the trash hole 8 is on the surface of the working surface 3, and is consistent with the running direction of the cotton roll of the carding machine, which is beneficial to the forward trash removal.

[0019] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection range of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
