Description

Technical Field:

[0001] The utility model relates to the technical field of carding machines, and more specifically to a feeding and barrel-changing device for a material barrel loaded with cotton yarn. Background Art:

[0002] A carding machine is a machine that makes loose fibers into slivers in wool spinning production. Its main function is to card the messy fibers into relatively straight single fibers, remove impurities therein, and mix fibers with different colors or qualities. The carded fibers are transported to a material barrel through rollers and stored and transferred through the material barrel. At present, in order to facilitate the replacement of the material barrel loaded with carded fibers, a material barrel changing mechanism is provided. The changing mechanism includes a machine base, a driving shaft is arranged on the machine base, three transposition arms are arranged on the driving shaft, and two groups of guide wheel assemblies are arranged on the transposition arms. The driving shaft drives the transposition arms to rotate around the driving shaft, and then the guide wheels on the guide wheel assemblies on the transposition arms push the material barrel to slide on the ground for transposition. There are two problems in the barrel-changing process: 1. When the material barrel slides on the ground, the friction is large, and there is varying degrees of wear at the bottom of the material barrel; 2. Because the friction is large, the reaction force of the material barrel on the guide wheel is large. The structure of one group of guide wheel assemblies is a support column fixed on the transposition arm, and multiple guide wheels are sleeved and connected to the support column. The lower end of the support column is suspended, so the acting points of the reaction force are concentrated on the upper part of the support column, and the support column is bent and deformed. Content of the Utility Model:

[0003] The purpose of the utility model is to provide a feeding and barrel-changing device for a material barrel loaded with cotton yarn aiming at the deficiencies of the prior art. A moving base connected to the support column is added, changing the sliding friction between the material barrel and the ground into rolling friction, which can avoid the wear at the bottom of the material barrel; and at the same time reduce the deformation of the support column.

[0019] Example: See Figures 1 to 3 As shown, a device for changing the bucket during the blanking of a material bucket for loading cotton yarn includes a transposition machine base 1. A vertical driving shaft 2 is arranged on the transposition machine base 1. The upper end of the driving shaft 2 extends out of the transposition machine base 1 and is fixedly connected with three transposition arms 3 which are evenly distributed in a ring shape. The transposition arm 3 includes an inner support arm 31, and an inclined outer support arm 32 is formed at the outer end of the inner support arm 31; Three blanking stations are arranged around the transposition machine base 1, and the three blanking stations are respectively located between adjacent transposition arms 3. Inner guide wheel assemblies 5 and outer guide wheel assemblies 4 are respectively arranged on both sides of the blanking station. The outer guide wheel assembly 4 includes a support column 41 fixedly connected to the outer end of the outer support arm 32, and a plurality of outer guide wheels 42 are connected to the support column 41 through bearings; The inner guide wheel assembly 5 includes a guide wheel bracket 53 fixedly connected to the outer side wall of the outer circle of the inner support arm 31. An inner guide wheel 51 is arranged below the guide wheel bracket 53. A T-shaped positioning column 52 is inserted into the inner guide wheel 51, and the upper end of the positioning column 52 is inserted and fixed on the guide wheel bracket 53. Moving bases 6 connected to the transposition arms 3 are respectively arranged directly below the blanking stations;

[0020] The moving base 6 includes a circular carrying chassis 61. A plug shaft 611 is formed in the middle of the lower end face of the carrying chassis 61. The lower end of the plug shaft 611 passes through the positioning disc 62 and is inserted and fixed on the support chassis 63. A plurality of balls 64 are embedded in the lower end face of the support chassis 63; An ear 621 is formed on the outer wall of one side of the positioning disc 62, and the ear 621 extends out of the outer wall of the carrying chassis 61 and is inserted and fixed at the lower end of the support column 41.

[0021] The lower end face of the transposition machine base 1 and the lower end of the outer wall of the ball 64 are in the same horizontal plane, that is, the moving base 6 contacts the ground through the ball 64 and moves on the ground through the ball 64.

[0022] The diameter of the outer guide wheel 42 on the outer guide wheel assembly 4 is larger than the width of the outer support arm 32. In some cases, the height of some material buckets is higher than that of the transposition machine base 1. Therefore, when the material bucket is arranged on the moving base 6, there is no interference problem with the outer support arm 32.

[0023] An upper anti-collision retaining ring 9 and a lower anti-collision retaining ring 7 are respectively inserted and fixed at the upper and lower ends of the position-changing machine base 1. The upper anti-collision retaining ring 9 and the lower anti-collision retaining ring 7 can prevent the material barrel from hitting the position-changing machine base 1.

[0024] The position-changing machine base 1 is rectangular. T-shaped auxiliary brackets 10 are respectively fixed on the side walls on each side of the position-changing machine base 1. The outer ends of the auxiliary brackets 10 are respectively fixed on the inner walls of the upper anti-collision retaining ring 9 and the lower anti-collision retaining ring 7.

[0025] A flange 71 with an L-shaped cross-section and bent outward is formed on the lower side of the lower anti-collision retaining ring 7. An annular limiting groove is formed in the flange 71 and the lower anti-collision retaining ring 7. A circular rotating sleeve 8 is inserted into the limiting groove of the lower anti-collision retaining ring 7. A plurality of connecting rods 65 are fixed to the upper side of the rotating sleeve 8 protruding from the limiting groove. The outer ends of the connecting rods 65 are respectively fixed to the outer wall of the positioning disk 62. The connecting rods 65 can be used to pull the moving base 6. Thus, when the outer guide wheel assembly 4 pushes the material barrel to move, the reaction force on the support column 41 is reduced, and the problem of deformation of the support column 41 is reduced.

[0026] The diameter of the inner wall of the rotating sleeve 8 is equal to the diameter of the outer wall of the lower anti-collision retaining ring 7.

[0027] A circular positioning convex ring 612 is formed on the upper end surface of the bearing chassis 61. The positioning convex ring 612 can be opposite to the concave platform at the bottom of the material barrel, facilitating the positioning of the material barrel on the moving base 6.

[0028] Working principle: The present invention is a device for unloading and changing the material barrel for loading cotton yarn. The structure of the device for unloading and changing the material barrel is as Figure 1 Therefore, it is mainly used to solve the problems of wear at the bottom of the material barrel and bending deformation of the support column 41;

[0029] It is provided with a moving base 6. The moving base 6 contacts the bottom surface through balls 64. At the same time, through the connection between the positioning disk 62 and the support column 41, the moving base 6 is realized to rotate and change positions around the position-changing machine base 1 together with the position-changing arm 3 by means of the support column 41;

[0030] When the friction force decreases, the reaction force on the support column 41 decreases, and the probability of deformation of the support column 41 can be reduced.

[0031] The embodiments are used to exemplarily illustrate the present invention, rather than to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the right protection of the present invention shall be as listed in the claims of the present invention.
