[0018] The structure and working principle of the tearing and loosening device for wool felt provided by the present invention are further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0019] In the description of the present invention, unless otherwise specified, the terms "up / down", "inside / outside", "front / back", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0020] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "provided with" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model.

[0021] like Figure 1 As shown, the structure of the tearing and loosening device for wool felt includes a frame 1, in which a plurality of pairs of rollers 2 driven by a motor are arranged. The pairs of rollers 2 include an upper shaft roller 21 and a lower shaft roller 22 rotating in opposite directions, and a rolling channel is formed therebetween. The pairs of rollers 2 located at the front end of the rolling channel are guide rollers 31, whose surface is smooth or provided with claws. The pairs of rollers 2 located at the rear end of the rolling channel are tearing rollers 32, whose surface is provided with claws, needle cloth or indentation patterns. The rotation speed of the tearing roller 32 is higher than that of the guide roller 31.

[0022] Its working principle is as follows: a plurality of pairs of rollers are arranged in the frame 1 of the device, and the upper roller 21 and the lower roller 22 of the pair of rollers 2 rotate in opposite directions (that is, the upper roller rotates clockwise and the lower roller rotates counterclockwise), which are used to eat the wool felt raw material, and then a rolling channel is formed between the two. The pair of rollers 2 located at the front end of the rolling channel is the guide roller 31, which is used to eat the transmission wool felt, and the pair of rollers 2 located at the rear end of the rolling channel is the tearing roller 32, which has a higher rotation speed than the guide roller 31. The relative rotation speed difference between the two causes the wool wrapped around the guide roller 31 to be gradually torn off. Through the rotation of the tearing roller 32, the felt-like wool raw material becomes loose and fluffy, achieving a pre-opening effect, which is convenient for the later opening and combing processing.

[0023] In the tearing and loosening device structure constituting the above-mentioned wool felt material,

[0024] As a preferred embodiment, a wool wrapping roller 33 is provided between the wool guide roller 31 and the wool tearing roller 32. The wool wrapping roller 33 rotates synchronously with the wool guide roller 31, that is, the wool wrapping roller 33 extends the rolling channel of the roller, and also ensures that the wool tearing roller 32 fully and repeatedly tears and loosens the wool felt material. The outside of the wool wrapping roller 33 and the wool tearing roller 32 are both provided with rubber sleeves, and the surface of the rubber sleeves is provided with a mesh-like indentation pattern, so that the shaft rollers can more effectively carry the wool felt material, and the transmission efficiency and wool tearing effect are better;

[0025] In order to effectively achieve the relative speed difference between the hair tearing roller 32 and the hair winding roller 33 and the hair guide roller 31, the hair winding roller 33 and the hair guide roller 31 are connected to the first motor 41 via a first transmission mechanism, and the hair tearing roller 32 is connected to the second motor 42 via a second transmission mechanism;

[0026] Specifically, the first transmission mechanism includes a gear 51 provided at the end of the lower shaft roller of the wool winding roller 33 and a gear 52 provided at the end of the lower shaft roller of the wool guide roller 31. The gears (51, 52) are connected to the gear 40 set on the output shaft of the first motor 41 through a chain. The sub-gear set at the end of the lower shaft roller of the wool winding roller 33 (blocked by the gear 51, attached) Figure 1 The transmission group composed of the first transmission gear 61 and the second transmission gear 62 is meshed with the gear 51' of the upper shaft roller of the wool winding roller 33 in sequence, and the sub-gear (blocked by the gear 52, attached) at the end of the lower shaft roller of the wool guide roller 31 is connected. Figure 1 (not shown) The transmission group composed of the third transmission gear 63 and the fourth transmission gear 64 is sequentially meshed with the gear 52' ​​provided at the upper shaft roller end of the hair guide roller 31; this gear transmission structure enables the hair guide roller 31 and the hair winding roller 33 to rotate synchronously and at the same speed;

[0027] The first transmission mechanism and the second transmission mechanism are respectively arranged on both sides of the frame 1. Figure 2As shown, the second transmission mechanism includes a gear 53 provided at the end of the lower shaft roller of the tearing roller 32, the gear 53 is connected to the gear 40' set on the output shaft of the second motor 42 through a chain, and the sub-gear set at the end of the lower shaft roller of the tearing roller 32 (blocked by the gear 53, attached Figure 2 (not shown) The transmission group consisting of the fifth transmission gear 65 and the sixth transmission gear 66 is meshed and connected in sequence with the gear 53' provided at the upper roller end of the tearing roller 32; this gear transmission structure realizes the relatively independent rotation of the tearing roller 32 and ensures that the speed difference between the tearing roller 32 and the guide roller 31 and the winding roller 33 is constant and easy to adjust to each other;

[0028] Preferably, a conveyor belt 7 is provided at the front end of the wool guide roller 31, and a feeding shaft roller 8 is provided above the conveyor belt 7. The surface of the feeding shaft roller 8 is provided with claws, and the claws are convex ridges 80 provided along the axial direction. The cross section of the convex ridge 80 is triangular or diamond-shaped. The conveyor belt 7 and the feeding shaft roller 8 are connected with the rolling channel in the frame 1, so that the cashmere felt raw materials can be quickly and continuously fed in, thereby improving the tearing and loosening (pre-opening) processing efficiency;

[0029] Furthermore, the gear mounted on the end of the feed shaft roller 8 is connected to the pinion mounted on the end of the hair guide roller 31 via a synchronous chain. That is, the feed shaft roller 8 and the hair guide roller 31 of the counter-roller mechanism rotate synchronously and at the same speed, thereby achieving uniform and stable feeding and transmission of the raw materials.

[0030] As an equivalent alternative, the pinion 30 mounted on the end of the guide roller 31 can also be connected to the gear 71 on the end of the rotating shaft of the conveyor belt 7 via a synchronous chain, thereby also achieving the effect of synchronous transmission.

[0031] ——Preferably, the ends of the upper and lower shaft rollers of the above-mentioned hair guide roller 31 and the ends of the upper and lower shaft rollers of the hair tearing roller 32 are respectively placed in the door-shaped frames 9 on both sides of the frame 1, and the ends of the upper shaft rollers of the hair guide roller 31 or the hair tearing roller 32 are provided with sliders 91, which are placed in the grooves on the inner side of the door-shaped frame 9. The sliders 91 are connected to the crossbeams of the door-shaped frame 9 through pre-tightening springs 92. The door-shaped frame 9 ensures that the upper and lower shaft rollers of the roller pair run stably and are relatively independent, which is convenient for maintenance and replacement. The pre-tightening springs 92 are connected with the sliders 91 at the ends of the shaft rollers to achieve pre-tightening of the shaft rollers and constant force in the rolling channel;

[0032] As the slider 91 moves in the groove, the upper roller will vibrate up and down. To ensure the stability of the gear meshing transmission at its end, other gears meshing with the upper roller gear can be set in the vertical slide groove of the frame 1 through their shafts.

[0033] The above-described embodiments are only used to illustrate the technical solution of the present invention and are not limiting conditions for the implementation of the present invention. Therefore, any other modifications or equivalent replacements of configuration dimensions and internal structures made to the technical solution of the present invention should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
