[0001] The utility model relates to the technical field of base cloth production, and specifically to a base cloth feeding device. Background Art

[0002] Fabric conveying is an important part of industrial production, which involves conveying fabric materials from one place to another, usually in a production line or during processing. Fabric, as the base layer of composite materials or products, needs to be conveyed stably and efficiently to ensure the continuity of the production process and the quality of the product. In the production of fabric rewinding, the fabric needs to be cut into small pieces of fixed size, and then each small piece is stacked and rolled.

[0047] Reference Figure 1~Figure 4 The utility model proposes a base cloth feeding device, including a power conveying roller 200 rotatably arranged on a bracket 100; a pressure roller 300 rotatably arranged on the bracket 100, the pressure roller 300 is located above the power conveying roller 200, and the pressure roller 300 and the power conveying roller 200 bracket 100 form a conveying space; a fixed roller 400 is rotatably arranged on the bracket 100, and along the base cloth conveying direction, the power conveying roller 200 and the fixed conveying roller are arranged in sequence; a lifting member 500 is lifted and arranged on the bracket 100, and the lifting member 500 and the fixed roller 400 form a clamping space; a cutting knife 600 is movably arranged on the bracket 100, and the cutting knife 600 is located between the power conveying roller 200 and the lifting member 500, and the moving direction of the cutting knife 600 is the same as the axial direction of the power conveying roller 200.

[0048] In this embodiment, the base fabric passes through the conveying space, the cutting position of the cutting knife 600, and the clamping space in sequence. The power conveying roller 200 and the pressure roller 300 use the friction between them to realize the conveying of the base fabric. The lifting member 500 can press the base fabric by rising close to the fixed roller 400. The tensioning device before the power conveying roller 200 and the pressure roller 300 can also provide tensioning force for the base fabric. One end of the base fabric is pressed by the pressure roller 300 and the lifting member 500, and the other end is stretched by the tensioning device, so that the base fabric between the power conveying roller 200 and the fixed roller 400 is in a tensioned state, which is convenient for the cutting knife 600 to cut the base fabric. By using the cutting knife 600 and the clamping space to be arranged behind the power conveying roller 200 in sequence, the tensioning device used by the power conveying roller 200 can not only act on the conveying of the base fabric by the power conveying roller 200, but also act on the cutting of the base fabric by the cutting knife 600.

[0049] Furthermore, it also includes a base cloth frame 700 arranged on the bracket 100, and the base cloth frame 700 is used to place the base cloth roll; a tensioning roller 800 is swingably arranged on the bracket 100, and the tensioning roller 800 is located between the base cloth frame 700 and the power transmission roller 200; a limiting roller 900 is rotatably arranged on the bracket 100, and the tensioning roller 800 swings to approach or move away from the limiting roller 900, and a tensioning space is formed between the tensioning roller 800 and the limiting roller 900.

[0050] When the tension roller 800 is in motion, the base cloth roll is placed on the base cloth frame 700, and the tensioning roller 800 swings to put the base cloth between the base cloth frame 700 and the power conveying roller 200 in a tensioned state. The base cloth is drawn out from the base cloth frame 700, bypasses the bottom of the tensioning roller 800 and enters the conveying space. The downward swing of the tensioning roller 800 can play a role in tensioning the base cloth, and when the tensioning roller 800 swings upward, the base cloth between the base cloth frame 700 and the power conveying roller 200 is in a relaxed state. After the tensioning roller 800, the base cloth, and the limiting roller 900 abut against each other, the base cloth passes between the tensioning roller 800 and the limiting roller 900, and the friction between the tensioning roller 800, the limiting roller 900 and the base cloth can provide tensioning force for the base cloth. After the power conveying roller 200 is actuated, the base cloth between the tensioning space and the conveying space is in a tensioned state.

[0051] Furthermore, it also includes a driving member 1000 disposed on the bracket 100; a lead screw 1100 is rotatably disposed on the bracket 100, the driving member 100 is used to drive the lead screw 1100 to rotate, and the cutting knife 600 is threadedly connected to the lead screw 1100.

[0052] In this embodiment, the cutting knife 600 is threadedly connected to the lead screw 1100. By rotating the lead screw 1100, the cutting knife 600 can slide in a direction perpendicular to the conveying direction of the base cloth, and cut off the base cloth between the conveying space and the clamping space. The cutting knife 600 is moved by the lead screw. When the driving member 1000 does not move, the cutting knife 600 can be in a stable moving state, which is beneficial to improving the cutting quality.

[0053] Furthermore, it also includes a first bevel gear 1200 arranged on the driving member 1000; a worm 1300 rotatably arranged on the bracket 100; a second bevel gear 1400 arranged on the worm 1300; a worm wheel 1500 arranged on the tensioning roller 800, the worm 1300 is meshed with the worm wheel 1500, and the worm wheel 1500 drives the tensioning roller 800 to swing.

[0054] In this embodiment, the first bevel gear 1200 and the second bevel gear 1400 can change the driving direction of the driving member 1000, so that the driving member 1000 can simultaneously drive the mutually perpendicular lead screw 1100 and the screw to rotate, so that the tension roller 800 and the cutting knife 600 can realize the action linkage, and when the cutting knife 600 moves to cut the base cloth, the tension roller 800 swings to tension the base cloth. The transmission mode of the worm gear 1500 and the worm 1300 can prevent the tension roller 800 from swinging in the opposite direction when the cutting knife 600 cuts the base cloth, thereby affecting the cutting quality.

[0055] Furthermore, the adjusting screw 1600 is rotatably arranged on the bracket 100, and the adjusting screw 1600 is threadedly connected with the lifting member 500. After the adjusting screw 1600 rotates, the lifting member 500 rises or falls.

[0056] In this embodiment, the lifting member 500 is threadedly connected to the adjusting screw 1600, and the lifting member 500 can be controlled to rise or fall by rotating the adjusting screw 1600. The adjusting screw 1600 is used to control the lifting and lowering action of the lifting member 500. The structure is simple and the action is stable. The lifting member 500 can withstand the axial force of the adjusting screw 1600, which is convenient for adapting to the clamping force between the lifting member 500 and the fixed rod.

[0057] Furthermore, the first gear 1700 is arranged on the worm 1300 ; the second gear 1800 is arranged on the adjusting screw 1600 , and the first gear 1700 is transmission-connected with the second gear 1800 .

[0058] In this embodiment, the first gear 1700 and the second gear 1800 use a chain drive to transmit the power on the worm 1300 to the adjusting screw 1600, so that a driving member 1000 can rotate forward and reverse, and at the same time realize the rise or fall of the lifting member 500, and press or loosen the base cloth with the fixed roller 400, the tensioning roller 800 swings to tension the base cloth and the cutting knife 600 moves to cut the base cloth. The movement of the lifting member 500, the tensioning roller 800, and the cutting knife 600 can make the necessary actions of cutting the base cloth can be synchronized, which is easier to control.

[0059] Furthermore, the lifting member 500 includes a lifting plate 510 which is lifted and set on the bracket 100, and the lifting plate 510 is threadedly connected to the adjusting screw 1600; a sliding member 520 is slidably set on the lifting plate 510, and after the lifting plate 510 rises, the sliding member 520 abuts against the fixed roller 400; there are a plurality of elastic members 530, and the two ends of the plurality of elastic members 530 are respectively set on the lifting plate 510 and the sliding member 520.

[0060] In this embodiment, the lifting plate 510 and the sliding member 520 are connected by the elastic member 530, the adjusting screw 1600 rotates, the lifting plate 510 rises, the sliding member 520 first contacts the sliding member 520, and the base cloth is pressed, the cutting knife 600 moves to the edge of the base cloth and starts to cut the base cloth, the driving member 1000 continues to move, and the elastic member 530 is compressed. By the elastic member 530 between the lifting plate 510 and the sliding member 520, the lifting plate 510 and the sliding member 520 can have a movable amount, and the distance between the sliding member 520 and the fixed roller 400 can be reduced as much as possible, so as to ensure that when the lifting plate 510 and the cutting knife 600 act synchronously, the sliding member 520 first contacts the fixed roller 400 to press the base cloth, so as to prevent the base cloth from being offset due to the action of the cutting knife 600.

[0061] Furthermore, the contact point between the fixed roller 400 and the sliding member 520 is lower than the highest point of the power transmission roller 200 .

[0062] In this embodiment, the contact point between the fixed roller 400 and the sliding member 520 is lower than the highest point of the conveying roller. After the base cloth is cut by the cutting knife 600, when the base cloth is subsequently conveyed in the direction of the fixed roller 400 by the powered conveying roller 200, since the base cloth is made of a soft material, the contact point between the fixed roller 400 and the sliding member 520 is set lower than the highest point of the powered conveying roller 200. This can prevent the front end of the base cloth from being sunken due to gravity, and the base cloth from being bent due to the contact with the sliding member 520 when entering the clamping space.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
