Description

Technical Field

[0001] The utility model relates to the technical field of opening machines, and more specifically, to a feed roller drive mechanism of an opening machine. Background Art

[0002] The feed roller, as a part of the carding machine, is mainly responsible for evenly feeding the cotton layer into the working area of the carding machine to ensure that the cotton fibers are fully carded and cleaned during the subsequent processing. It realizes the holding and conveying of the cotton layer through the cooperation with components such as the feed plate. The feed roller usually consists of components such as a roller body, a bearing seat, and bearings, and its surface may be specially treated (such as covered with card clothing) to increase the holding force on the cotton layer. The two feed rollers need to rotate to feed the cotton and also move the distance between them according to the thickness of the cotton layer. The commonly used transmission method currently is that the change gear on one roller drives the change gear on the other roller to rotate through two intermediate change gears, so that the other roller rotates, and thus the two rollers rotate synchronously and in opposite directions to compress the cotton layer and send it out. However, during this process, since the roller moves due to the change in the thickness of the cotton layer, the distance between the gears changes, resulting in greater impact and noise of the equipment and poorer transmission stability, which is not conducive to improving the product quality. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a feed roller drive mechanism of an opening machine that can improve the change in gear spacing and reduce the vibration and impact noise of the equipment.

[0005] Further, it further includes a mounting plate. The third gear is installed on the mounting plate, and a limiting notch for the shaft end of the fourth gear to be adaptively inserted is opened on the mounting plate, and the fourth gear moves along the limiting notch; the slider is slidably connected to the top end of the mounting plate.

Detailed implementation mode

[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0021] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0022] The following is further described in conjunction with specific embodiments. Referring to Figures 1-4 As shown, this embodiment is a feeding roller transmission mechanism of a bale opener, including a first feeding roller 1 and a second feeding roller 2 arranged in parallel side by side. One end of the first feeding roller 1 is provided with a fixed block 3 and a first gear 5, and one end of the second feeding roller 2 is provided with a slider 4 and a second gear 6; a third gear 7, which is meshed and connected with the first gear 5; a fourth gear 8, which is respectively meshed and connected with the third gear 7 and the second gear 6, and a first connecting arm 9 is connected between the third gear 7 and the fourth gear 8; a second connecting arm 10 is arranged between the second gear 6 and the fourth gear 8, so that when the second feeding roller 2 and the second gear 6 move, the fourth gear 8 revolves around the third gear 7 and rotates meshingly; specifically, the first connecting arm 9 is a planetary rotating arm. When excessive cotton enters the first feeding roller 1 and the second feeding roller 2, while the four gears of the gear train rotate, the second feeding roller 2 will be displaced by extrusion to the right as Figure 4 As shown, the second gear 6 will also move to the right. At this time, the second connecting arm 10 will drive the fourth gear 8 to perform epicyclic motion. When the fourth gear 8 rotates, it drives the first connecting arm 9. During this process, the center distance between the third gear 7 and the fourth gear 8 remains unchanged due to the first connecting arm 9, and the center distance between the second gear 6 and the fourth gear 8 remains unchanged due to the second connecting arm 10. The meshing between the gears remains normal, and there will be no collision and impact between the gears caused by displacement, reducing the noise, and the set sensor will stop the driving motor from running when the roller is overloaded to achieve a protection effect.

[0023] The first gear 5 and the second gear 6 are gears with the same diameter and the same number of teeth, and the third gear 7 and the fourth gear 8 are gears with the same diameter and the same number of teeth. Thus, when the power drives the first feed roller 1, the second feed roller 2 rotates in the opposite direction and at the same speed as the first feed roller 1 through the gear train.

[0024] This embodiment further includes a mounting plate 11. The third gear 7 is mounted on the mounting plate 11, and a limiting notch 111 for the shaft end of the fourth gear 8 to fit into is formed on the mounting plate 11. The fourth gear 8 moves along the limiting notch 111; the slider 4 is slidably connected to the top end of the mounting plate 11; specifically, the third gear 7 makes a planetary motion. In order to reasonably and smoothly guide it, the fourth gear 8 moves along a trajectory along the limiting notch 111.

[0025] In addition, this limiting notch 111 is arc-shaped, and the angle of this arc is less than 90 degrees.

[0026] As Figure 2 and Figure 3 shown, preferably, a mounting notch 41 adapted to the thickness of the mounting plate 11 is provided at the lower end of the slider 4; specifically, this mounting notch 41 is a right angle and fits the two side surfaces of the mounting plate 11. When the second feed roller 2 is squeezed, the slider 4 linearly slides along the mounting plate 11 to avoid axial deviation.

[0027] As Figure 2 shown, there are two first connecting arms 9, and the first connecting arms 9 are respectively arranged on both sides of the mounting plate 11; similarly, there are two second connecting arms 10, and the second connecting arms 10 are respectively arranged on both sides of the mounting plate 11, avoiding setting a single-sided connection between the third gear 7 and the fourth gear 8, which may cause deviation and jamming during rotation.

[0028] Referring to Figure 1 and Figure 4 shown, a top block 13 is provided at one end of the mounting plate 11 in this embodiment, and a return spring 12 is connected between the top block 13 and the slider 4; the axis of the return spring 12 is parallel to the upper end surface of the mounting plate 11; specifically, the distance between the slider 4 and the fixed block 3 is pushed in real time by the elastic force of the return spring 12, that is, the distance between the two rollers is adjusted in real time according to different amounts of cotton entering between the first feed roller 1 and the second feed roller 2.

[0029] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
