Description

Technical Field

[0001] The utility model belongs to the technical field of looms, and in particular relates to a double-shaft loom. Background Art

[0002] Existing looms generally have single-axis warp delivery, which makes it difficult to produce fabrics with high warp density. In order to overcome this shortcoming, people have thought of adding another warp beam above the loom and using two warp beams to deliver warp at the same time to complete high warp density fabrics.

[0003] However, in actual use, it was found that the synchronization of the double-axis warp feeding using the same transmission system was poor, and there was still a large error (this error was mainly caused by the gap between the gears and the chain), which resulted in different warp tensions on different warp beams, easily causing the woven fabric to be uneven. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing technology and provide a double-axis loom for solving the technical problem that the existing double-axis loom still has rotation errors using the same transmission system, resulting in inconsistent tensioning forces of the warps on the double axes, affecting the flatness of the fabric.

[0005] The utility model solves the above technical problems with the following technical solutions: a double-axis loom comprising:

[0006] A loom frame, wherein the loom frame is provided with a lower warp beam, and the lower warp beam is driven by a driving wheel;

[0007] a pair of upper warp beam fixing arms, wherein the pair of upper warp beam fixing arms are welded to both sides of the loom frame;

[0008] An upper warp beam, the upper warp beam being arranged between a pair of upper warp beam fixing arms via a bearing seat;

[0009] a first encoder connected to the lower warp beam;

[0010] a second encoder connected to the upper warp beam;

[0011] A servo motor connected to the upper warp beam;

[0012] A controller is electrically connected to the first encoder, the second encoder and the servo motor.

[0013] The present utility model also adds an upper warp beam on the basis of the existing loom. The difference is that the upper warp beam and the lower warp beam no longer use the same drive system (the original drive system of the loom), and the upper warp beam is independently driven by a servo motor; the rotation strokes of the upper warp beam and the lower warp beam are detected by the first encoder and the second encoder, and then the servo motor is controlled by the controller to make the upper warp beam and the lower warp beam rotate synchronously, reducing and even eliminating the rotation error between the upper warp beam and the lower warp beam.

[0014] Furthermore: a chute is provided on the top surface of the upper warp beam fixing arm, a protruding slide rail is provided in the chute, a sliding seat is provided on the slide rail, and the bearing seat is fixed on the sliding seat;

[0015] A locking bolt is provided on the sliding seat.

[0016] Beneficial effect of this step: By finely adjusting the position of the sliding seat in the chute, the precise adjustment of the position of the upper warp beam can be achieved.

[0017] Furthermore: the slide rail is a T-shaped rail or a dovetail rail.

[0018] Beneficial effect of this step: Both the T-shaped rail and the dovetail rail have high precision.

[0019] Furthermore: a cushion block is provided between the sliding seat and the chute, and the cushion block is composed of several gaskets with different thicknesses.

[0020] Beneficial effect of this step: The cushion block is used to fill the gap between the sliding seat and the chute, preventing the bearing seat from shifting when the upper warp beam works for a long time, and affecting the synchronism between the upper warp beam and the lower warp beam.

[0021] Furthermore: the servo motor and the upper warp beam are connected by a pair of bevel gears.

[0022] Beneficial effect of this step: By changing the direction of the servo motor through the bevel gears, the main body of the servo motor is parallel to the frame of the loom, reducing the total width of the loom and avoiding occupying space.

[0023] The beneficial effects of the present utility model are:

[0024] 1. Combining the first encoder, the second encoder, the controller and the servo motor, the servo motor drives the upper warp beam to rotate, maintaining synchronism with the rotation of the lower warp beam, and avoiding errors caused by the gear and chain drive system;

[0025] 2. Through the chute and sliding seat structure, small-range and precise adjustment of the position of the upper warp beam can be achieved, so that the upper warp beam can obtain better warp feeding tension. Description of the Drawings

[0041] Embodiment

[0042] As Figure 1 and Figure 2 shown, a double - shaft loom provided by the present utility model includes:

[0043] A loom frame 1, the loom frame 1 is provided with a lower warp beam 2, and the lower warp beam 2 is driven by a driving wheel;

[0044] A pair of upper warp beam fixing arms 3, and a pair of the upper warp beam fixing arms 3 are welded on both sides of the loom frame 1. In order to strengthen the structural strength of the upper warp beam fixing arms 3, upper tie rods 32 are respectively arranged above the upper warp beam fixing arms 3, and the upper tie rods 32 are connected to the reinforcing plates 11 arranged on the loom frame 1. Lower support rods 31 are arranged below the upper warp beam fixing arms 3, and the lower support rods 31 are connected to the loom frame 1;

[0045] An upper warp beam 4, and the upper warp beam 4 is arranged between a pair of the upper warp beam fixing arms 3 through a bearing block 5;

[0046] A first encoder 7, and the first encoder 7 is connected to the lower warp beam 2;

[0047] A second encoder 8, and the second encoder 8 is connected to the upper warp beam 4;

[0048] A servo motor 6, and the servo motor 6 is connected to the upper warp beam 4;

[0049] A controller 9, and the controller 9 is electrically connected to the first encoder 7, the second encoder 8 and the servo motor 6.

[0050] The present utility model also adds an upper warp beam 4 on the basis of the existing loom. The difference is that the upper warp beam 4 and the lower warp beam 2 no longer use the same transmission system (the original transmission system of the loom), and the upper warp beam 4 is independently driven by the servo motor 6; the rotation strokes of the upper warp beam 4 and the lower warp beam 2 are detected by the first encoder 7 and the second encoder 8, and then the servo motor 6 is controlled by the controller 9, so that the upper warp beam 4 and the lower warp beam 2 can rotate synchronously, reducing and even eliminating the rotation error between the upper warp beam 4 and the lower warp beam 2. [[ID=I9]]

[0051] Specifically, the main function of the encoder is to convert mechanical motion into electrical signals or digital signals for feeding back position, speed or angle information to the controller 9.

[0052] The functions of the encoder include:

[0053] Position control: The encoder can accurately measure the position, angle or linear displacement of the measured object, provide accurate position feedback signals, and thus achieve precise position control. 2. Speed control: By detecting the pulse signals output by the encoder, the real-time speed information of the measured object can be calculated. The controller 9 can adjust according to the speed feedback signals to achieve precise speed control.

[0054] 3. Motion control: Based on the position and speed signals provided by the encoder and combined with the specific diameters of the upper warp beam 4 and the lower warp beam 2, the controller 9 can accurately control the rotation speed and acceleration and deceleration of the upper warp beam 4, and achieve precise control of the adaptation between the upper warp beam 4 and the lower warp beam 2.

[0055] Such asFigure 1 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 3 and Figure 4 , a chute is provided on the top surface of the upper warp beam fixing arm 3. A protruding slide rail 34 is provided in the chute. A slide seat 33 is provided on the slide rail 34, and the bearing seat 5 is fixed on the slide seat 33.

[0056] A locking bolt 331 is provided on the slide seat 33.

[0057] Due to possible differences between the upper warp beam 4 and the lower warp beam 2 in the initial stage, by finely adjusting the position of the slide seat 33 in the chute, the precise adjustment of the position of the upper warp beam 4 can be achieved, so that the upper warp beam 4 and the lower warp beam 2 rotate synchronously.

[0058] Based on the above technical solution, the slide rail 34 is a T-shaped rail or a dovetail rail.

[0059] Both the T-shaped rail and the dovetail rail have high precision. When the slide rail 34 is a T-shaped rail, the locking bolt 331 is on the side of the slide seat 33. When the slide rail 34 is a dovetail rail, the locking bolt 331 is on the top surface of the slide seat 33.

[0060] Based on the above technical solution, a spacer 332 is provided between the slide seat 33 and the chute. The spacer 332 is composed of several gaskets with different thicknesses.

[0061] The spacer 332 is used to fill the gap between the slide seat 33 and the chute, to prevent the upper warp beam 4 from driving the bearing seat 5 to displace after long-term operation, which affects the synchronism between the upper warp beam 4 and the lower warp beam 2. In addition, several gaskets with different thicknesses have various combined effects and can be suitable for gaps of different sizes.

[0062] Based on the above technical solution, the servo motor 6 is connected to the upper warp beam 4 through a pair of bevel gears 41.

[0063] By changing the direction of the servo motor 6 through the bevel gears 41, the main body of the servo motor 6 is parallel to the loom frame 1, which is easier to install. In addition, it can also reduce the total width of the loom and avoid occupying space.

[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
