[0002] The yarn tube is the main component for winding yarn. After use, there will usually be residual yarn tails on the yarn tube, forming a yarn cone with yarn tails. Before processing, these yarn cones are mostly piled up in a corner or collection box, and the residual yarn tails need to be taken out one by one to deal with. The traditional way of taking them out is manual, which is time-consuming, labor-intensive and inefficient, and difficult to cooperate with automatic yarn tail removal equipment for loading.

[0003] In addition, when the yarn bobbins with tail yarns are stacked, the tail yarns on adjacent yarn bobbins tend to become entangled with each other. When one of them is taken out, the entangled yarn will pull out the other one, which may easily lead to abnormal feeding of the automatic tail yarn removal equipment. Utility Model Content

[0032] like Figures 1 to 6As shown, the automatic feeding device for yarn bobbins with tail yarns provided by the utility model includes a base 10, a storage box 20, a guide plate 30, and a drum block, wherein the base 10 is a frame-type base, the drum box 20 is used to stack the yarn bobbins with tail yarns, the drum box 20 is arranged on the base 10, the top of which is open to form an opening 21, the bottom of the drum box 10 is provided with a bottom plate 22, the bottom plate 22 extends obliquely from the back to the front, the rear edge of the bottom plate 22 is connected to the bottom of the drum box 10, and a notch 23 is provided in front of the bottom plate 22; the guide plate 30 is connected to the front edge of the opening 21 and extends obliquely forward and downward, the front edge of the guide plate 30 is docked with the feeding port of the automatic tail yarn removal device (not shown in the figure); the drum block is connected to the storage box 10 The inner walls of both sides of the barrel box 10 are symmetrically arranged on the left and right sides of the notch 23, and the barrel block extends in the up and down direction, and the upper end surface of the barrel block extends downwardly from the back to the front, and the inclination degree of the upper end surface of the barrel block is the same as the inclination degree of the bottom plate 22 and is greater than or equal to the inclination degree of the guide plate 30; specifically, the barrel block includes a plurality of fixed barrel blocks 41 and a plurality of movable barrel blocks 42, and the movable barrel blocks 42 are staggered with the fixed barrel blocks 41, and the barrel blocks located at the front and rear are both movable barrel blocks 42; the movable barrel block 42 has an upper working position and a lower working position. When the movable barrel block 42 is in the upper working position, the front edge of the upper end surface of the movable barrel block 42 is aligned with the fixed barrel block 41 in front of the movable barrel block 42 The rear edge of the upper end surface of the blocking block 41 is flush with the front edge of the movable blocking block 42 in the front and the rear edge of the guide plate 30. When the movable blocking block 42 is in the lower working position, the rear edge of the upper end surface of the movable blocking block 42 is flush with the front edge of the upper end surface of the fixed blocking block 41 behind the movable blocking block 42, and the rear edge of the rearmost movable blocking block 42 is flush with the front edge of the bottom plate 22. In this way, the movable blocking block 42 can lift the yarn bobbins accumulated on the bottom plate 22 in sequence by moving up and down until they roll onto the guide plate 30; further, the guide plate 30 is also provided with a dividing rod 31 which can be moved up and down, and the dividing rod 31 extends in the up and down direction, and the dividing rod 31 has two and corresponds to the guide plate 30 The two side edges are arranged, and the spacing between the two dividing rods 31 is greater than the width of the tail yarn on the yarn bobbin and less than the length of the yarn bobbin. The upper ends of the two dividing rods 31 are equipped with electric heating strips 32. When the dividing rod 31 moves downward to the extreme position, the electric heating strips 32 are attached to the upper surface of the guide plate 30, and the yarn bobbin on the guide plate 30 can smoothly roll into the feeding port. When the dividing rod 31 moves upward to the extreme position, the yarn bobbin behind the dividing rod 31 on the guide plate 30 is blocked and separated from the yarn bobbin in front. The electric heating strip 32 burns off the tail yarn entangled between the two yarn bobbins during the movement of the dividing rod 31, thereby realizing the anti-entanglement function. The automatic feeding device has a sophisticated structure, significant effect, low cost, and is easy to promote and use.

[0033] For the convenience of setting, in this embodiment, the dividing rod 31 can be moved up and down and is passed through the guide plate 30. Furthermore, the up and down movement of the dividing rod 31 is synchronized and reversed with the up and down movement of the movable stop barrel block 42.

The reversal means that when the movable stop barrel block 42 moves upward, the dividing rod 31 moves downward, and when the movable stop barrel block 42 moves downward, the dividing rod 31 moves upward.

[0034] In this embodiment, an I-shaped connecting plate 43 is provided below the notch 23. The I-shape refers to the projection of the connecting plate 43 in the up and down directions. The two cross bars of the connecting plate 43 are connected to the lower end portions of all the movable blocking cylinder blocks 42, and the middle portion of the longitudinal bar of the connecting plate 43 is connected to a first vertical bar 431 extending downwardly; a cross beam 33 extending in the left and right directions is provided below the guide plate 30, and the two ends of the cross beam 33 are connected to the lower end portions of the two dividing rods 31, and the middle portion of the cross beam 33 is connected to a second vertical bar 331 extending downwardly.

The rotational sliding connection can be achieved by the cooperation between the waist-shaped hole and the cross bar inserted in the waist-shaped hole, which will not be repeated here.

[0035] The advantage of such a setting is that it can not only realize the synchronous reverse movement of the above-mentioned dividing rod 31 and the movable stop barrel block 42, but also enable the first transmission rod 11 and the second transmission rod 12 to form a lever structure, so as to adjust the amplitude of the up and down movement of the dividing rod 31 and the movable stop barrel block 42 and the force distance of driving the dividing rod 31 and the movable stop barrel block 42 to move up and down, and adapt to yarn bobbins with tail yarns of different models and different tail yarn thicknesses.

[0036] In this embodiment, the driving mechanism 13 is fixed on the left side of the base 10. In order to control the rhythm of driving the material distribution rod 31 and the movable blocking cylinder block 42 to move up and down, the driving mechanism 13 is a combination of a stepping motor and a screw pair.

[0037] Since the diameters of yarn bobbins of different models are different, in order to further improve the applicability of the automatic loading device, in this embodiment, the front edge of the upper end face of the barrel block is connected to an extension plate 44 extending forward and downward, and the inclination of the extension plate 44 is the same as the inclination of the upper end face of the barrel block. The total length of the upper end face of the barrel block and the upper surface of the extension plate 44 in the front-to-back direction is 1.1 to 1.9 times the diameter of a single yarn bobbin, and the extension plate 44 and the barrel block where it is located are integrally formed.

[0038] To ensure that the yarn bobbin rolls smoothly on the guide plate 30, further, the guide plate 30 is provided with flanges 34 that are folded upward vertically on both sides, and the dividing rod 31 is located on the inner side of the flange 34. When the yarn bobbin rolls on the guide plate 30, the flange 34 is used to level the end face of the yarn bobbin.

[0039] To facilitate feeding, in this embodiment, the opening 21 is lower in the front and higher in the back, and the plane where the edge of the opening 21 is located is the same plane as the plane where the material guide plate 30 is located.

[0040] It should be noted that in order to facilitate the smooth rolling of the yarn bobbin on the guide plate 30 and the moderate rolling speed, the inclination of the guide plate 30 (the angle between the plane where the guide plate 30 is located and the horizontal plane) should be controlled at 5 to 15 degrees. Specifically in this embodiment, the inclination is 10 degrees.

[0041] Similarly, in order to facilitate bobbin lifting and maintain moderate lifting efficiency, the inclination between the upper end surface of the bobbin block and the bottom plate 22 is preferably controlled at 15 to 25 degrees. Specifically in this embodiment, the inclination is 10 degrees.
