With the development of society, modern main looms often use shuttleless looms, and shuttleless looms have great advantages in output and quality. The loom needs to guide the weaving during the production process.

[0003] A Chinese patent with authorization announcement number CN219971362U discloses a cloth guiding mechanism of a loom, including a bottom plate, support plates are fixedly connected to the left and right sides of the upper surface of the bottom plate, the top of the support plates are fixedly connected to fixed rods, the front and rear ends of the fixed rods are jointly rotatably connected to a transmission shaft, the outside of the transmission shaft is fixedly connected to a cloth guide roller, the outside of the cloth guide roller is fixedly connected to a thread, the top of the right end of the transmission shaft is fixedly connected to a pulley, and the two pulleys are connected by a belt; the above device has the following shortcomings: the first cleaning rod and the second cleaning rod repeatedly clean the passing cloth, and after long-term use, dust is easily accumulated on the cleaning rods, resulting in poor cleaning effect. Utility Model Content

[0004] The utility model aims to provide a cloth guiding device for a loom, which can better and continuously clean the cloth being guided and improve the quality of subsequent processing.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a cloth guiding device for a loom, comprising a machine body, on which a winding roller, a cloth guiding roller and a cleaning roller are rotatably arranged, a driving motor for driving the winding roller to rotate is installed on the machine body, the winding roller and the cloth guiding roller rotate synchronously through a transmission belt, the cleaning roller is provided with two upper and lower ones, a dust hood facing the cleaning roller is fixed to the machine body, the dust hoods are two mirror-image-arranged ones, a scraper is fixed in the dust hood through a locking assembly, the bottom end of the scraper is in contact with the cleaning roller, the dust hood is connected to a dust collecting box through a dust collecting pipe, a negative pressure fan is installed in the dust collecting box, the winding roller is provided with a cloth pressing assembly, and the cloth pressing assembly includes a pressing plate in contact with the winding roller.

[0006] By adopting the above technical scheme, the driving motor drives the winding roller to rotate to wind up the cloth passing through the cleaning roller. The rotation of the winding roller drives the cloth guide roller to rotate synchronously through the transmission belt for guiding. When the cloth passes through the cleaning roller, the cleaning roller cleans the dust on the cloth. At the same time, when the cleaning roller passes through the dust hood during the rotation of the cleaning roller, the scraper in the dust hood scrapes off the dust on the cleaning roller. The dust scraped into the dust hood falls into the dust collecting box through the dust suction pipe under the action of the negative pressure fan, thereby improving the cleanliness of the cleaning roller and improving the subsequent processing quality. Before the winding roller rotates to wind up the cloth, a pressing plate is used to press the front end of the cloth onto the winding roller, thereby solving the problem of needing to wrap the cloth with the winding roller before winding up the cloth, thereby further improving the processing efficiency.

[0007] The utility model is further configured as follows: the scraper is configured to be inclined so that the bottom end of the scraper is in contact with the cleaning roller.

[0008] By adopting the above technical solution, the scraper is tilted so that it can better guide the dust scraped off the cleaning roller into the dust hood, which is conducive to scraping the dust falling into the dust hood and dropping it into the dust collecting box through the dust suction pipe under the action of the negative pressure fan.

[0009] The utility model is further configured as follows: the locking assembly includes a mounting seat fixed in the dust hood, the mounting seat is provided with a connecting groove, connecting plates placed in the connecting grooves are fixed at both ends of the scraper, a first wedge block and a second wedge block matching the first wedge block are slidably disposed on the mounting seat, the second wedge block pushes the first wedge block to be pressed above the connecting plate, and an adjusting screw threadedly connected to the mounting seat is rotatably disposed on the second wedge block.

[0010] By adopting the above technical solution, when installing the scraper, the connecting plates at both ends of the scraper are placed in the connecting grooves, and the adjusting screw is rotated to make the adjusting screw rotate and descend. At the same time, the adjusting screw drives the second wedge block to descend, and the second wedge block pushes the first wedge block to move above the connecting plate, and finally the connecting plate is pressed tightly against the mounting seat, completing the relative fixation between the scraper and the mounting seat, which is convenient for quick installation and disassembly of the scraper, and cleaning or replacement of the scraper.

[0011] The utility model is further configured as follows: a telescopic spring is fixedly connected between the first wedge block and the mounting seat.

[0012] By adopting the above technical solution, when disassembling the scraper, the adjusting screw is rotated in the opposite direction to make the adjusting screw rise. The rising adjusting screw drives the second wedge block to rise. The second wedge block no longer squeezes and pushes the first wedge block, so that the first wedge block returns under the pull of the telescopic spring. The first wedge block is detached from the top of the connecting plate, and then the scraper can be quickly removed from the mounting seats on both sides.

[0013] The utility model is further configured as follows: the first wedge block is fixed with a guide rod inserted and slid in the mounting seat, the mounting seat is provided with an inner cavity for the guide rod to be inserted, and the telescopic spring is sleeved outside the guide rod.

[0014] By adopting the above technical solution, when the first wedge block slides relative to the mounting seat, the guide rod is inserted and slid in the inner cavity to guide the sliding of the first wedge block, making the installation and disassembly process more stable.

[0015] The utility model is further configured as follows: mounting plates are fixed at both ends of the winding roller, the cloth pressing assembly also includes an adjustment seat sliding on the mounting plate, the adjustment seat is provided with an adjustment groove, a connecting block is hinged in the adjustment groove, the pressing plate is fixed to the bottom of the connecting block, and an adjustment bolt is threadedly connected in the adjustment groove to fix the connecting block.

[0016] By adopting the above technical solution, before the winding roller rotates to wind the cloth, the front end of the cloth is placed on the winding roller, the connecting block is rotated relative to the adjusting seat so that the connecting block drives the pressure plate to press the front end of the cloth, and then the connecting block and the adjusting groove are relatively fixed using the adjusting bolt to complete the fixation of the front end of the cloth, avoiding multiple windings of the cloth and improving processing efficiency.

[0017] The utility model is further configured as follows: the adjusting bolt is provided with an elliptical head, and the connecting block is provided with a through hole for the elliptical head to pass through.

[0018] By adopting the above technical scheme, the bottom end of the adjusting bolt rod passes through the through hole and is threadedly connected to the inner wall of the adjusting groove. When the connecting block and the adjusting groove are relatively fixed, the adjusting screw is rotated relative to the adjusting groove so that the elliptical head and the through hole are in a relatively vertical state, thereby limiting the connecting block from being separated from the adjusting groove. When the connecting block and the adjusting groove need to be relatively rotated, the adjusting screw is rotated relative to the adjusting groove so that the elliptical head and the through hole are in a relatively parallel state. The connecting block can be flipped relative to the adjusting seat and the elliptical head can pass through the through hole, thereby lifting the pressure plate.

[0019] The utility model is further configured as follows: the pressing plate is configured to be in an arc shape that fits the outer surface of the winding roller.

[0020] By adopting the above technical solution, the pressing plate presses the cloth tightly against the outer surface of the winding roller, which is beneficial for the winding roller to wind up the cloth.

[0021] The utility model is further configured as follows: a limiting rod inserted and slidably inserted into the mounting plate is fixed to the adjusting seat, and a limiting spring sleeved on the outside of the limiting rod is fixed between the adjusting seat and the mounting plate.

[0022] By adopting the above technical solution, when the winding roller finishes winding the fabric, the pressure plate is taken out from the fabric roll by sliding the adjustment seat relative to the mounting plate; when the adjustment seat is slid relative to the mounting plate, the limit rod slides through the mounting plate to achieve guidance, and when the adjustment seat is released, the adjustment seat returns to its original position under the action of the limit spring.

[0023] The utility model is further configured as follows: fixing plates are fixed on both sides of the adjustment seat, and the fixing plates are threadedly connected with fixing bolts extending into the mounting plate.

[0024] By adopting the above technical solution, when the cloth is rolled up, the adjusting seat and the mounting plate are relatively fixed by the fixing bolts, so as to prevent the pressing plate from being separated from the cloth during the rolling process of the winding roller.

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

[0026] 1. The driving motor drives the winding roller to rotate and reel the fabric passing through the cleaning roller. The rotation of the winding roller drives the guide roller to rotate synchronously through the transmission belt for guiding. When the fabric passes through the cleaning roller, the cleaning roller cleans the dust on the fabric. At the same time, when the cleaning roller passes through the dust hood during its rotation, the scraper in the dust hood scrapes off the dust on the cleaning roller. The dust scraped into the dust hood falls into the dust collecting box through the dust suction pipe under the action of the negative pressure fan, thereby improving the cleanliness of the cleaning roller and improving the quality of subsequent processing;

[0027] 2. When installing the scraper, place the connecting plates at both ends of the scraper in the connecting grooves, rotate the adjusting screw to make the adjusting screw rotate and descend, and at the same time, the adjusting screw drives the second wedge block to descend, and the second wedge block pushes the first wedge block to move above the connecting plate, and finally presses the connecting plate tightly on the mounting seat, completing the relative fixation between the scraper and the mounting seat, which is convenient for quick installation and removal of the scraper, cleaning or replacement of the scraper;

[0028] 3. Before the winding roller rotates to wind the fabric, place the front end of the fabric on the winding roller, rotate the connecting block relative to the adjusting seat so that the connecting block drives the pressing plate to press the front end of the fabric, and then use the adjusting bolt to fix the connecting block and the adjusting groove relatively to complete the fixation of the front end of the fabric, avoiding multiple steps of winding the fabric and improving processing efficiency.
