Description

Technical Field

[0001] The utility model relates to the technical field of linen production, in particular to a controllable feeding device for linen production. Background Art

[0002] Linen cloth is woven by twisting flax into threads. Its fiber is strong and not easy to tear or puncture. In the production process of linen cloth, a roving machine is needed to make flax silk thread into roving in preparation for the later linen cloth weaving.

[0003] For example, in the prior art, a feeding device of a roving machine for linen production with a publication number of CN217809845U is used. The feeding device clamps the silk thread through a limiting roller and a matching roller, and applies a rotational resistance to the matching roller. Although it is convenient to adjust the tension of the fiber silk thread during the feeding process to avoid the problem of silk thread breakage, when the feeding is stopped, the output of the silk thread will also be quickly stopped. Due to the lack of a structure to control the rotational resistance of the rotating seat, the rotating seat will continue to rotate due to rotational inertia, resulting in excessive continuous release of the wire, resulting in a wire explosion phenomenon, which in turn makes it difficult to feed again.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0030] Embodiment 1: In view of the lack of a structure for controlling the rotational resistance of the rotating seat in the prior art, the rotating seat will continue to rotate due to rotational inertia, causing excessive continuous wire release and resulting in wire explosion, which in turn makes it difficult to feed again. The following solution can be used to solve the problem;

[0031] See also Figure 1 - Figure 6 As shown, in this embodiment, a controllable feeding device for linen production includes a base 1, a mounting groove 11 is provided on the top of the base 1, which is used to install the control component 3 and control the rotation resistance of the rotating seat 12 and the fixed roller 13, and the rotating seat 12 and the fixed roller 13 are rotatably installed on both sides of the mounting groove 11, the rotating seat 12 is used to place the fiber strip coil 14, the fixed roller 13 is used to cooperate with the movable roller 43 to clamp the silk thread during the feeding process, and adjust the tension of the silk thread during the feeding process through the rotation resistance of the fixed roller 13, the outer side of the rotating seat 12 is sleeved with the fiber strip coil 14, the rotating seat 12 is provided with a clamping component 2 for fixing the fiber strip coil 14, and the control component 3 is provided in the mounting groove 11;

[0032] The control assembly 3 includes a screw rod 31 rotatably mounted in the mounting groove 11, one end of the screw rod 31 penetrates the outer side of the base 1 and is fixedly connected to a torsion wheel 1, and sliding rods 32 are symmetrically fixedly connected on both sides of the screw rod 31 in the mounting groove 11, and a resistance plate 33 threadedly connected to the screw rod 31 is slidably connected between the sliding rods 32, and a resistance friction plate 1 34 and a resistance friction plate 2 35 are respectively installed at both ends of the resistance plate 33;

[0033] The resistance plate 33 is driven to move in the mounting groove 11 by rotating the screw rod 31, and the resistance friction plate 1 34 and the resistance friction plate 2 35 on both sides of the resistance plate 33 are respectively in contact with the outer walls of the rotating seat 12 and the fixed roller 13, so as to simultaneously control the rotational resistance of the rotating seat 12 and the fixed roller 13, and adjust the position of the resistance plate 33 by the screw rod 31, thereby changing the adjustment of the rotational resistance of the rotating seat 12 and the fixed roller 13, so that when the wire feeding stops, it can effectively prevent the rotating seat 12 from continuing to rotate due to rotational inertia, causing the wire breaking phenomenon caused by excessive continuous wire release, and then making it difficult to feed again.

[0034] The two ends of the resistance plate 33 are respectively fixedly connected with an arc plate 1 36 and an arc plate 2 37, and the curvature of the arc plate 1 36 is adapted to the annular outer wall of the rotating seat 12, the resistance friction plate 1 34 is fixedly connected to the concave side of the arc plate 1 36, the curvature of the arc plate 2 37 is adapted to the annular outer wall of the fixed roller 13, and the resistance friction plate 2 35 is fixedly connected to the concave side of the arc plate 2 37.

[0035] The clamping assembly 2 includes a bidirectional screw rod 21 rotatably installed in the rotating seat 12. The top end of the bidirectional screw rod 21 extends through and extends to the outside of the rotating seat 12 and is fixedly connected to a torsion wheel 2, and a movable plate 22 is correspondingly threadedly connected to the bidirectional screw rod 21. A plurality of slide grooves 15 distributed in a circular array are penetrated and opened on the annular inner wall of the rotating seat 12. A clamping block 23 is slidably connected in each slide groove 15. A support rod 24 is hinged between the clamping block 23 and the corresponding movable plate 22. The fiber strip roll 14 is quickly mounted on the rotating seat 12. The two groups of movable plates 22 are driven to move away from each other by rotating the bidirectional screw rod 21, and with the cooperation of the corresponding support rod 24, multiple clamping blocks 23 are forced to slide out of the slide groove 15, thereby adapting to and fixing fiber strip rolls 14 of different sizes, thereby improving the application range of the feeding device.

[0036] The clamping block 23 is in a right-angled trapezoidal structure, so that a plurality of clamping blocks 23 are combined to form a cone-like structure, thereby better adapting to the shape of the inside of the fiber strip coil 14 and increasing the fixing effect, and a non-slip rubber pad 25 is fixedly connected to the side of the clamping block 23 away from the bidirectional screw rod 21, which is used to further increase the non-slip contact between the fiber strip coil 14 and the clamping block 23, so that the rotating seat 12 can avoid inertial rotation under the action of the control component 3, and prevent the fiber strip coil 14 from rotating on the rotating seat 12, and further prevent the wire breaking phenomenon caused by excessive continued wire release. A plurality of placement plates 16 distributed in a circular array are fixedly connected on the annular outer wall of the rotating seat 12 and located below the clamping block 23, which are used to support the bottom of the fiber strip coil 14 placed on the outside of the rotating seat 12, thereby improving the convenience of placement.

[0037] A U-shaped frame 4 rotatably connected to a fixed roller 13 is fixedly connected to the top of the base 1, and is used to enhance the rotation stability of the fixed roller 13 while rotatably installing a movable roller 43.

A spring 44 is fixedly connected between the U-shaped plate 42 and the U-shaped frame 4 and on the outside of the U-shaped pull rod 41. The movable roller 43 is tightly fitted with the fixed roller 13 through the compression elastic force of the spring 44 on the U-shaped plate 42, and is used to clamp the fiber thread. The rotation resistance of the fixed roller 13 is adjusted by the control component 3 to achieve adjustment of the thread tension during feeding.

[0038] A wire plate 45 is fixedly connected to one side of the U-shaped frame 4 close to the rotating seat 12, and a plurality of wire holes 46 in a trapezoidal structure are equidistantly provided on the wire plate 45 along its vertical direction. The wire holes 46 at different positions on the wire plate 45 are used to fix the pulling height of the wire to prevent the problem of the wire jumping up and down during feeding.

[0039] The working process and principle of the utility model are as follows:

[0040] During use, the utility model sets the fiber strip coil 14 on the rotating seat 12, rotates the bidirectional screw rod 21 to drive the two sets of movable plates 22 to move away from each other, and with the cooperation of the corresponding support rods 24, forces multiple clamping blocks 23 to slide out of the slide groove 15, so as to adapt to and fix fiber strip coils 14 of different sizes;

[0041] The wire end of the fiber strip coil 14 is passed through the wire hole 46 of the corresponding height between the fixed roller 13 and the movable roller 43. At this time, the U-shaped pull rod 41 is pulled to drive the movable roller 43 on the U-shaped plate 42 to separate from the fixed roller 13, so as to facilitate the wire to be passed between the fixed roller 13 and the movable roller 43. After passing, the U-shaped pull rod 41 is released and under the action of the compression elastic force of the spring 44, the movable roller 43 is driven to cooperate with the fixed roller 13 to clamp the wire, and then the wire is pulled and fed;

[0042] The rotating screw 31 drives the resistance plate 33 to move in the mounting groove 11, and the resistance friction plate 1 34 and the resistance friction plate 2 35 on both sides of the resistance plate 33 are respectively in contact with the outer walls of the rotating seat 12 and the fixed roller 13, thereby simultaneously controlling the rotational resistance of the rotating seat 12 and the fixed roller 13, and adjusting the position of the resistance plate 33 by the screw 31, thereby changing the adjustment of the rotational resistance of the rotating seat 12 and the fixed roller 13, so as to prevent the inertial rotation of the rotating seat 12 when the feeding is stopped.
