Description

Technical Field

[0001] The utility model relates to the technical field of cloth-stacking machines, in particular to an edge alignment mechanism of a cloth-stacking machine. Background Art

[0002] At present, cloth-stacking machines are widely used in cloth factories and printing and dyeing factories. Cloth-stacking machines can fold grey cloth or cloth after printing and dyeing, and fold the cloth neatly. In the process of cloth-stacking on the cloth-stacking machine, the cloth is easily wrinkled when it passes through guide rollers for many times, and the flatness is not ideal, resulting in unsatisfactory cloth-stacking effect, and finally the cloth cannot be aligned, affecting the cloth-stacking effect.

[0003] The Chinese patent with the authorization announcement number CN218931256U discloses a cloth-stacking machine capable of aligning edges, including side plates, two of which are symmetrically arranged, and a first guide roller assembly, a second guide roller assembly and a third guide roller assembly are arranged between the two side plates, a first fixed plate is arranged between the first guide roller assembly and the second guide roller assembly, the first fixed plate is fixedly connected between the two side plates, a shifting block is arranged at the top of the first fixed plate, a fixed block is fixedly connected at the bottom of the first fixed plate, and a scraper is arranged at the bottom of the fixed block. The above device has the following disadvantages: the shifting block drives the scraper to move to scrape the cloth, which is inefficient. Utility Model Content

[0004] The utility model aims to provide an edge alignment mechanism of a cloth-laying machine, which has the effect of automatically flattening the cloth.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a cloth-coding machine edge-aligning mechanism, comprising two symmetrically arranged side plates, a first guide roller, a second guide roller and a pressure roller are rotatably connected between the two side plates, a movable frame is symmetrically and slidably connected between the two side plates, the movable frame is located between the first guide roller and the second guide roller, an upper pressure roller is rotatably connected to the bottom of the movable frame, and a driving mechanism is installed between the two side plates to drive the two movable frames to reciprocate.

[0006] By adopting the above technical scheme, the cloth passes through the first guide roller, the second guide roller and the pressing roller in sequence. When the cloth passes between the first guide roller and the second guide roller, the driving mechanism drives the two moving frames to move back and forth in a mirror image, driving the two upper pressing rollers to move back and forth to scrape the cloth flat. The two upper pressing rollers respectively scrape the left and right parts of the cloth flat, shortening the moving process, saving labor and making the scraping work more efficient, thereby improving the automatic edge alignment effect.

[0007] The further setting of the present utility model is as follows: The driving mechanism includes a driving cylinder fixed to the bottom of one of the moving frames. A fixed frame located between the two moving frames is fixed between the two side plates. The output end of the driving cylinder is fixed to the fixed frame. A first connecting rod is hinged to the fixed frame, and two ends of the first connecting rod are respectively hinged to a second connecting rod between the two moving frames on both sides.

[0008] By adopting the above technical solution, when carrying out the leveling work, the output end of the driving cylinder extends or returns to drive one side of the moving frame to reciprocate relative to the side plate. This side of the moving frame pushes and pulls the first connecting rod to rotate relative to the fixed frame through the second connecting rod. The other end of the first connecting rod pushes and pulls the other side of the moving frame to reciprocate relative to the side plate through another second connecting rod, realizing the reciprocating relative movement of the two upper pressing rollers close to or away from each other, leveling the passing fabric, and being more efficient.

[0009] The further setting of the present utility model is as follows: Horizontal guide rods located on both sides of the fixed frame are fixed between the two side plates, and both sides of the moving frame are inserted and slidably connected to the horizontal guide rods.

[0010] By adopting the above technical solution, the moving frame slides relative to the horizontal guide rods between the two side plates, making the leveling work more stable.

[0011] The further setting of the present utility model is as follows: Two connecting frames slidably connected to the side plates are fixed to one side of the two moving frames away from the fixed frame. A lower pressing roller is rotatably connected to the connecting frame, and the upper pressing roller and the lower pressing roller are symmetrically arranged.

[0012] By adopting the above technical solution, when the two side moving frames slide and move, the lower pressing roller is driven to move synchronously through the connecting frame, so that the upper pressing roller and the lower pressing roller jointly press the upper and lower sides of the fabric flat, making the fabric more flat, and further improving the automatic edge alignment effect.

[0013] The further setting of the present utility model is as follows: First sliding rods are inserted and slidably connected to both sides of the moving frame. A first connecting block is fixed to the bottom of the first sliding rod. The upper pressing roller is rotatably connected between the two first connecting blocks. A first spring sleeved outside the first sliding rod is fixed between the first connecting block and the moving frame.

[0014] By adopting the above technical solution, the upper pressing roller contacts the upper surface of the fabric under the push of the first spring, flattening the upper surface of the fabric.

[0015] The further setting of the present utility model is as follows: Second sliding rods are inserted and slidably connected to the connecting frame. A second connecting block is fixed to the upper end of the second sliding rod. The lower pressing roller is rotatably connected between the two second connecting blocks. A second spring sleeved outside the second sliding rod is fixed between the second connecting block and the connecting frame.

[0016] By adopting the above technical solution, the lower pressing roller contacts the lower surface of the fabric under the push of the second spring, flattening the lower surface of the fabric; when the thickness of the fabric changes, the fabric pushes the first spring and the second spring to compress, the first sliding rod slides relative to the moving frame, and the second sliding rod slides relative to the connecting frame, changing the distance between the upper pressing roller and the lower pressing roller to adapt to the fabric thickness and improving the applicability of the device.

[0017] A further setting of the present utility model is that: the side plate is provided with a guiding hole, and the connecting frame extends between the first guiding roller and the second guiding roller after passing through the guiding hole.

[0018] By adopting the above technical solution, the connecting frame moves horizontally along the guiding hole, so that when the first guiding roller moves, it drives the second guiding roller to move synchronously through the connecting frame.

[0019] A further setting of the present utility model is that: an elevating mechanism for driving the pressing roller to lift is installed on the side plate.

[0020] By adopting the above technical solution, the elevating mechanism drives the pressing roller to lift to adjust the height of the pressing roller, and further adjusts the tension degree of the fabric.

[0021] A further setting of the present utility model is that: the elevating mechanism includes an elevating screw rod rotatably connected to one side plate and a vertical guiding rod fixed to the other side plate, an elevating block is threadedly connected to the elevating screw rod, a sliding block slides on the vertical guiding rod, and the pressing roller is rotatably connected between the elevating block and the sliding block.

[0022] By adopting the above technical solution, when adjusting the height of the pressing roller, the elevating screw rod rotates to drive the elevating block and the pressing roller to lift to adjust the height of the pressing roller.

[0023] A further setting of the present utility model is that: the elevating screw rod is driven to rotate by a motor installed on the side plate.

[0024] By adopting the above technical solution, the motor drives the elevating screw rod to rotate to automatically adjust the height of the pressing roller.

[0025] The beneficial effects of the present utility model are:

[0026] 1. The fabric passes through the first guiding roller, the second guiding roller and the pressing roller in sequence. When the fabric passes between the first guiding roller and the second guiding roller, the driving mechanism drives the two moving frames to reciprocate mirror-symmetrically, driving the two upper pressing rollers to reciprocate to flatten the fabric. The two upper pressing rollers flatten the left and right parts of the fabric respectively, shortening the moving process, saving labor and making the flattening work more efficient, thereby improving the automatic edge alignment effect;

[0027] 2. When the two side moving frames slide, the connecting frame drives the lower pressing roller to move synchronously, so that the upper pressing roller and the lower pressing roller jointly flatten the upper and lower sides of the fabric, making the fabric more flat, and thus improving the automatic edge alignment effect;

[0028] 3. When the thickness of the fabric changes, the fabric pushes the first spring and the second spring to compress. The first sliding rod slides relative to the moving frame, and the second sliding rod slides relative to the connecting frame, changing the distance between the upper pressing roller and the lower pressing roller to adapt to the fabric thickness, improving the applicability of the device; 4. The lifting mechanism drives the pressing roller to lift to adjust the height of the pressing roller, and thus adjust the tension degree of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

A first connecting rod 73 is hinged to the fixed frame 72. Two ends of the first connecting rod 73 are respectively hinged to a second connecting rod 74 between the moving frames 5 on both sides.

[0037] Furthermore, horizontal guide rods 8 located on both sides of the fixed frame 72 are fixed between the two side plates 1. The two sides of the moving frame 5 are inserted and slid on the horizontal guide rods 8.

[0038] Furthermore, two connecting frames 9 slidably connected to the side plates 1 are fixed to one side of the two moving frames 5 away from the fixed frame 72. A lower pressing roller 10 is rotatably connected to the connecting frame 9. The upper pressing roller 6 and the lower pressing roller 10 are symmetrically arranged.
