Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a wool twist yarn pre-processing device. Background Art

[0002] There are three main raw materials used for spinning in the prior art, namely, cotton and linen materials, animal hair materials and chemical materials. Cotton and linen materials can be spun directly, while animal hair materials need to be cleaned and broken up to reduce their density so that they become fluffy and loose before spinning operations can be carried out.

[0003] The utility model patent with authorization announcement number CN 217709783 U discloses a wool twist yarn pre-treatment and loosening device, including a conveyor, a frame is arranged below the conveyor, and a power source for driving the main roller to rotate is arranged at the outer end of the outer end of the side panel of the conveyor, the outer facade of the side panel of the conveyor is connected to a support frame, and cylinders are symmetrically and vertically installed on the inner sides of both ends of the upper surface of the support frame, and connecting plates are connected between the telescopic rods of the cylinders. A number of adjustment seats are threadedly connected on the connecting plates at intervals, and a bobbin is installed in the adjusting seat, and a clamping elastic line is installed on the bobbin. A number of bases are arranged at intervals on the outer sides of both ends of the upper surface of the support frame, and a number of elastic rods are vertically installed on the bases.

[0004] However, after actual application by technicians in this field, it was found that the above method still has some shortcomings. The most obvious one is that during the lifting and lowering process of the elastic line, one side thereof will rub against the inner wall of the groove and the outer wall of the tip. As the friction continues to increase, the operator needs to replace the elastic line regularly. Since there are multiple elastic lines, in actual application, the operator needs to spend a lot of time and energy each time to replace the elastic line, which is inconvenient in actual use.

[0005] Therefore, it is necessary to invent a wool twist yarn pre-treatment device to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a wool twist yarn pre-treatment fluff disintegration device, which is provided with a conveyor belt, a driving and lifting mechanism, a surrounding disintegration mechanism, a first trigger mechanism, an avoidance type limit mechanism and a second trigger mechanism, so that the driving and lifting mechanism can be used to lift the surrounding disintegration mechanism. During this process, the second trigger mechanism triggers the surrounding disintegration mechanism, and then switches the friction position between the annular elastic line and the groove to avoid excessive local wear. At the same time, during the rising process of the surrounding disintegration mechanism, the avoidance type limit mechanism will not block the surrounding disintegration mechanism, thereby reducing the wear speed of the annular elastic line. Subsequently, the driving and lifting mechanism drives the first trigger mechanism to trigger the avoidance type limit mechanism, so that the subsequent driving and lifting mechanism drives the surrounding disintegration mechanism When the structure descends to break up the wool, the avoidance limit mechanism can block the annular elastic line, thereby realizing the rebound and breaking up of the annular elastic line. In addition, during the descending process of the surrounding breaking up mechanism, due to the limitation of the overrunning clutch, the second trigger mechanism does not trigger the surrounding breaking up mechanism, thereby avoiding the movement of the annular elastic line and the elastic rod during the contact process and aggravating the wear, so as to solve the problem proposed in the above background technology that during the lifting and lowering process of the elastic line, one side of the elastic line will rub against the inner wall of the groove and the outer wall of the tip. As the friction continues to increase, the operator needs to replace the elastic line regularly.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides Figure 1-5 A wool twist yarn pre-processing and loosening device is shown, comprising a conveyor belt 1, wherein legs 2 are fixedly provided at the four corners of the bottom of the conveyor belt 1, a driving lifting mechanism 3 is provided at the bottom of the conveyor belt 1, a surrounding type loosening mechanism 4 is provided at the top of the driving lifting mechanism 3, first trigger mechanisms 5 are provided on both sides of the surrounding type loosening mechanism 4, avoidance type limiting mechanisms 6 are provided on both sides of the top of the conveyor belt 1, and second trigger mechanisms 7 are provided on the tops of the two groups of avoidance type limiting mechanisms 6.

[0028] like Figure 2As shown, the driving lifting mechanism 3 includes a base plate 31, a reciprocating screw 32, a driving motor 33, an inner sleeve 34, a first spring 35, an outer sleeve 36, a lifting plate 37, a limiting ring 38 and an outer sleeve 39, wherein the base plate 31 is fixedly sleeved on the outer sides of two adjacent legs 2, the reciprocating screw 32 passes through the base plate 31 and is rotatably connected to the base plate 31 through a bearing, the driving motor 33 is fixedly arranged at the bottom of the base plate 31 and is transmission-connected to the reciprocating screw 32, and the inner sleeve 34, the first spring 35 and the outer sleeve 36 are sleeved on the reciprocating screw 32 in sequence from top to bottom. On the outside, the inner sleeve 34 is slidingly connected to the reciprocating screw 32, the first spring 35 is fixedly connected between the inner sleeve 34 and the outer sleeve 36, the outer sleeve 36 is transmission-connected to the reciprocating screw 32 and is slidingly sleeved on the outside of the inner sleeve 34, the lifting plate 37 is fixedly set at the top of the inner sleeve 34 and is slidingly sleeved on the outside of two adjacent legs 2, the limiting ring 38 is fixedly sleeved on the outside of the adjacent legs 2 and is located above the lifting plate 37, and the outer sleeve plate 39 is fixedly sleeved on the top of the outer side of the outer sleeve 36 and is slidingly sleeved on the outside of two adjacent legs 2.

[0029] By setting the above structure, the driving motor 33 can drive the reciprocating screw 32 to rotate after it is started, and the reciprocating screw 32 drives the outer sleeve 36 to move upward when it rotates. During the upward movement of the outer sleeve 36, the surrounding breaking mechanism 4 is driven to move upward through the first spring 35, the inner sleeve 34 and the lifting plate 37, and the first trigger mechanism 5 is driven to move upward through the outer sleeve plate 39.

[0030] like Figure 3 As shown, the surrounding breaking mechanism 4 includes a plurality of annular elastic lines 41 and two groups of switching mechanisms, and any group of the switching mechanisms includes a first L-shaped plate 42, a driven shaft 43, a cam 44, a driving shaft 45 and a gear 46, wherein the first L-shaped plate 42 is fixedly arranged on the top side of the lifting plate 37, the driven shaft 43 passes through the first L-shaped plate 42 and is rotatably connected to the first L-shaped plate 42 through a bearing, a plurality of cams 44 are arranged, and a plurality of the cams 44 are evenly fixedly sleeved on the outside of the driven shaft 43, and any one of the annular elastic lines 41 is sleeved on the outside of two adjacent cams 44, the driving shaft 45 is connected to the end of the driven shaft 43 through an overrunning clutch, and the gear 46 is fixedly arranged at the end of the driving shaft 45.

[0031] By setting the above structure, when the surrounding breaking up mechanism 4 moves up, the rack 72 drives the adjacent gear 46 to rotate. At this time, the gear 46 drives the driving shaft 45 to rotate through the driving shaft 45, and then the two concave wheels 44 drive the annular elastic line 41 to rotate and change position. When the annular elastic line 41 moves down subsequently, the annular elastic line 41 slips off the inner side of the groove 66 under the action of tension, and then recovers under the action of its own elasticity. In this process, the annular elastic line 41 breaks up the wool on the top of the conveyor belt 1.

[0032] like Figure 4 As shown, the first trigger mechanism 5 includes a column 51, a connecting sleeve 52, a second spring 53, a second L-shaped plate 54, a trigger rod 55 and a first bar magnet 56, wherein the column 51 is fixedly arranged on the top of the outer sleeve 39, the connecting sleeve 52 is slidably sleeved on the outside of the column 51, the second spring 53 is fixedly connected between the column 51 and the connecting sleeve 52, the second L-shaped plate 54 is fixedly arranged on the top of the connecting sleeve 52, a plurality of trigger rods 55 are provided, and the plurality of trigger rods 55 are evenly fixedly arranged on the inner side of the second L-shaped plate 54, the trigger rod 55 extends to below the adjacent L-shaped rocker 64, and the first bar magnet 56 is fixedly arranged on the top of the second L-shaped plate 54.

[0033] By setting the above structure, when the second L-shaped plate 54, the connecting sleeve 52 and the multiple trigger rods 55 cannot move downward, as the outer sleeve 36 continues to descend, the outer plate 39 continuously stretches the second spring 53 through the column 51. After the second spring 53 is stretched to the extreme value, as the outer sleeve 36 continues to move downward, the column 51 drives the first bar magnet 56 to detach from the bottom of the second bar magnet 73 through the second spring 53, the connecting sleeve 52 and the second L-shaped plate 54, and then the first trigger mechanism 5 is reset and the avoidance limit mechanism 6 is reset in turn.

[0034] like Figure 5 As shown, the avoidance limiting mechanism 6 includes an L-shaped frame 61, a rotating pin 62, a torsion spring 63, an L-shaped rocker arm 64, an elastic rod 65 and a groove 66, wherein the L-shaped frame 61 is fixedly arranged on the top of the conveyor belt 1, the rotating pin 62 passes through the L-shaped frame 61 and is rotatably connected to the L-shaped frame 61 through a bearing, the torsion spring 63 is sleeved on the outside of the rotating pin 62 and fixedly connected between the L-shaped frame 61 and the rotating pin 62, the L-shaped rocker arm 64 is fixedly sleeved on the outer end of the rotating pin 62, the elastic rod 65 is fixedly arranged at the bottom of the L-shaped rocker arm 64, the elastic rod 65 in the two groups of the avoidance limiting mechanisms 6 are in opposite directions, and the groove 66 is opened at the outer bottom of the elastic rod 65.

[0035] By setting the above structure, after the trigger rod 55 contacts the horizontal part of the adjacent L-shaped rocker arm 64, as the trigger rod 55 continues to rise, the L-shaped rocker arm 64 drives the elastic rod 65 to rotate around the rotating pin 62 as the axis, and the elastic rod 65 rotates to a vertical state. At this time, the annular elastic line 41 is located on the inner side of the adjacent groove 66. When the annular elastic line 41 subsequently descends, the inner wall of the groove 66 blocks the annular elastic line 41.

[0036] like Figure 4 As shown, the second trigger mechanism 7 includes a T-shaped plate 71, a rack 72 and a second bar magnet 73, wherein the T-shaped plate 71 is fixedly arranged on the top of the adjacent L-shaped frame 61, the rack 72 is fixedly arranged on the bottom of the T-shaped plate 71 and meshes with the adjacent gear 46, and the second bar magnet 73 is fixedly arranged on the bottom of the T-shaped plate 71 and is located directly above the adjacent first bar magnet 56.

[0037] By setting the above structure, during the ascending process of the surround-type dispersing mechanism 4, the rack 72 drives the gear 46 to rotate to adjust the friction position of the annular elastic line 41. When the surround-type dispersing mechanism 4 is subsequently descended, the rack 72 drives the gear 46 to rotate in the opposite direction. However, due to the limitation of the overrunning clutch, the gear 46 only drives the driving shaft 45 to rotate, while the driving shaft 45 does not rotate. The second bar magnet 73 is set to adsorb the first bar magnet 56, so that when the column 51 descends, the second L-shaped plate 54, the connecting sleeve 52 and the multiple trigger rods 55 do not move downward. At this time, as the outer sleeve 36 continues to descend, the outer sleeve plate 39 continues to stretch the second spring 53 through the column 51.

[0038] The present invention also discloses a wool breaking method of a wool twist yarn pre-treatment loosening device, and the method specifically comprises the following steps:

[0039] S1, spreading the wool to be scattered on the top of the conveyor belt 1 away from the surrounding scattering mechanism 4, and starting the conveyor belt 1 after the spreading is completed, so that the conveyor belt 1 drives the wool into the wool scattering station located inside the surrounding scattering mechanism 4, and then starting the drive motor 33 to start the wool scattering operation. During this process, the wool to be scattered continues to be spread on the top of the conveyor belt 1 away from the surrounding scattering mechanism 4;

[0040] S2, after the driving motor 33 is started, it drives the reciprocating screw 32 to rotate. When the reciprocating screw 32 rotates, it drives the outer sleeve 36 to move upward. During the upward movement of the outer sleeve 36, the first spring 35, the inner sleeve 34 and the lifting plate 37 drive the surrounding scattering mechanism 4 to move upward. At the same time, the outer sleeve plate 39 drives the first trigger mechanism 5 to move upward. During the upward movement of the surrounding scattering mechanism 4, the rack 72 drives the adjacent gear 46 to rotate. At this time, the gear 46 drives the driving shaft 45 to rotate through the driving shaft 45, and then the two concave wheels 44 drive the annular elastic line 41 to rotate and transpose.

[0041] S3, when the upward movement distance of the outer sleeve 36 reaches the first threshold, the top of the lifting plate 37 fits with the bottom of the limit ring 38, and the surrounding scattering mechanism 4 arrives at the preset position. During the upward movement of the surrounding scattering mechanism 4, the two elastic rods 65 adjacent to the annular elastic line 41 in the surrounding scattering mechanism 4 do not block the annular elastic line 41. At the same time, due to the obstruction of the limit ring 38, the lifting plate 37 and the inner sleeve 34 cannot continue to rise. Subsequently, as the outer sleeve 36 continues to rise, the first spring 35 is continuously compressed, and the outer plate 39 continues to drive the first trigger mechanism 5 to move upward;

[0042] S4, when the upward movement distance of the outer sleeve 36 reaches the second threshold, the trigger rod 55 contacts the horizontal portion of the adjacent L-shaped swing rod 64, and then as the trigger rod 55 continues to rise, the L-shaped swing rod 64 drives the spring rod 65 to rotate around the rotating pin 62 as the axis;

[0043] S5, when the upward movement distance of the outer sleeve 36 reaches the third threshold, the elastic rod 65 rotates to a vertical state, and the outer sleeve 36 moves to the top of the reciprocating thread on the outside of the reciprocating screw 32. Subsequently, as the reciprocating screw 32 continues to rotate, the outer sleeve 36 moves down and resets. At this time, the annular elastic line 41 is located on the inner side of the adjacent groove 66, and at the same time, the first bar magnet 56 is adsorbed and connected with the adjacent second bar magnet 73. During the downward movement of the outer sleeve 36, since the first bar magnet 56 is adsorbed by the second bar magnet 73, the second L-shaped plate 54, the connecting sleeve 52 and the multiple trigger rods 55 do not move downward. At this time, as the outer sleeve 36 continues to descend, the outer plate 39 continuously stretches the second spring 53 through the column 51;

[0044] S6, when the outer sleeve 36 descends to a fourth threshold, the compressed first spring 35 is restored, and as the outer sleeve 36 continues to descend, the lifting plate 37 drives the surrounding scattering mechanism 4 to descend. During the descending process of the surrounding scattering mechanism 4, the annular elastic line 41 is blocked by two adjacent elastic rods 65 on the left and right sides respectively, and at the same time, the rack 72 drives the gear 46 to rotate in the opposite direction. At this time, due to the limitation of the overrunning clutch, the driven shaft 43 does not rotate;

[0045] S7, when the outer sleeve 36 descends to a fifth threshold, the annular elastic line 41 slips off from the inner side of the groove 66 under the action of tension, and then recovers under the action of its own elasticity. In this process, the annular elastic line 41 breaks up the wool on the top of the conveyor belt 1;

[0046] S8, when the outer sleeve 36 descends to a sixth threshold, the second spring 53 is stretched to an extreme value, and as the outer sleeve 36 continues to move downward, the column 51 drives the first bar magnet 56 to detach from the bottom of the second bar magnet 73 through the second spring 53, the connecting sleeve 52 and the second L-shaped plate 54, and then the first trigger mechanism 5 is reset and the avoidance limit mechanism 6 is reset in turn;

[0047] S9, when the outer sleeve 36 descends to the seventh threshold, the outer sleeve 36 moves to the bottom of the reciprocating thread on the outside of the bottom plate 31, and then as the reciprocating screw 32 continues to rotate, the outer sleeve 36 moves up again. During this process, the conveyor belt 1 is started to output the scattered wool, and at the same time drives the placed wool to enter the wool scattering station located on the inner side of the surrounding scattering mechanism 4.

[0048] It should also be noted that the first threshold, the second threshold and the third threshold increase in sequence, and the fourth threshold, the fifth threshold, the sixth threshold and the seventh threshold increase in sequence. At the same time, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold and the seventh threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme;

[0049] When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 32, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, the sixth threshold value and the seventh threshold value are all specific values.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
