[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] As Figures 1 to 5 shown, a fully automatic glass fiber felt cutting machine includes an unwinding mechanism 1, a felt pulling mechanism 2, a cutting mechanism 3 and a moving platform 4. There are ≥4 felt rollers 1a in the unwinding mechanism 1. Each felt roller 1a winds a roll of glass fiber felt and discharges the material synchronously and at the same speed. The cutting mechanism 3 is located above the felt pulling mechanism 2. The moving direction of the moving platform 4 includes vertical and horizontal directions. It is located below the felt pulling mechanism 2. When the moving platform 4 receives the material (cut sheet glass fiber felt) below the felt pulling mechanism 2, the height of its top surface platform slowly decreases, and the glass fiber felts are stacked layer by layer on it. When a certain amount of glass fiber felts are loaded, the moving platform 4 moves outward horizontally to transport away several cut and stacked glass fiber felts; a pressing roller group 5 is arranged between the felt pulling mechanism 2 and the unwinding mechanism 1. The felt pulling mechanism 2 includes two pairs of toothed pressing plates 2a arranged up and down. The teeth on the opposite sides of the two pairs of toothed pressing plates 2a are staggered. The teeth of one side can be inserted into the tooth gaps of the other side. The distance between the two upper toothed pressing plates 2a and the two lower toothed pressing plates 2a is adjustable to adapt to different thicknesses of glass fiber felts. The distance between the upper and lower toothed pressing plates 2a of each pair of toothed pressing plates 2a can be adjusted independently. The pair of toothed pressing plates 2a far from the felt pulling mechanism 2 can move horizontally, linearly, forward and backward at high speed. The two upper toothed pressing plates 2a can be lifted and lowered to realize the pulling and moving operation process after clamping the glass fiber felt. Specifically, multiple rolls of glass fiber felts pass through the pressing roller group 5, and then pass through a pair of toothed pressing plates 2a close to the felt pulling mechanism 2 until the head of the glass fiber felt is located between a pair of toothed pressing plates 2a far from the felt pulling mechanism 2. This pair uses an air cylinder to control the upper toothed pressing plate 2a to press down and clamp the glass fiber felt with the lower toothed pressing plate 2a, and then translate in the direction away from the pressing roller group 5. According to the required cutting length, after moving to the set position, the upper toothed pressing plate 2a in a pair of toothed pressing plates 2a close to the felt pulling mechanism 2 presses down and also clamps the glass fiber felt, waiting for cutting.

[0025] Next, the cutting mechanism 3 operates. The cutting mechanism 3 includes a servo motor 3a with a rotating cutter 3b connected to its rotating shaft. The operating speed of the rotating cutter 3b is ≥6500 rpm. The servo motor 3a is arranged on the cross rail through a slider and can be translated based on it. The moving direction of the servo motor 3a is perpendicular to the transmission and moving direction of the fiberglass mat. The servo motor 3a drives the rotating cutter 3b to rotate and also translates itself. The edge of the rotating cutter 3b contacts the fiberglass mat with both ends clamped by the toothed pressure plates 2a for cutting. The horizontal moving distance of the servo motor 3a is adjustable according to the width of the fiberglass mat to be cut.

[0026] Among them, the pair of pressure rollers 5 includes a fixed roller 5a below and an up-and-down movable roller 5b above. A tension roller 1b and a supporting roller 6 are arranged between them and the mat winding roller 1a; the rotating central axes of the mat winding roller 1a, the tension roller 1b, and the supporting roller 6 are all parallel. A shaft-mounted tension sensor 1b-1 is arranged between the tension roller 1b and the lower bracket. The tension sensor 1b-1 is an instrument for measuring the magnitude of the coil tension value. According to the real-time measured tension value, the unwinding speed of the mat winding roller 1a can be adjusted. The shaft-mounted tension sensor adopts the full-bridge resistance strain gauge principle and is processed by an integrated circuit operational amplifier to detect the magnitude of the tension. This tension sensor has high measurement accuracy, good stability, is durable, corrosion-resistant, dust-proof, and easy to install, and is widely used in coiling control equipment and production lines such as printing, packaging, film, metal foil, compounding, coating, leather, lithium batteries, shearing, papermaking, rubber, textiles, wire and cable, and film.

[0027] The mat winding roller 1a is an air shaft 1a-2 with a magnetic powder clutch-brake 1a-1 connected to one end. The surface of the air shaft 1a-2 is provided with air-controlled protruding or retracting expansion keys. The air shaft 1a-2 can achieve rapid locking and release with the reel core through simple inflation and deflation operations. The inflation operation time is short, usually only taking a few seconds to complete, greatly improving the speed and efficiency of replacing the reel core; the magnetic powder clutch-brake 1a-1 can achieve unwind and rewind tension control.

[0028] The air shaft 1a-2 is connected to a deviation correction electric cylinder 1a-3, and the deviation correction electric cylinder 1a-3 drives the air shaft 1a-2 to move horizontally axially; an ultrasonic sensor 7 is arranged on the bracket of the fixed tension roller 1b, and the ultrasonic sensor 7 is located on the side where the fiberglass mat moves.

[0029] The mobile platform 4 includes a platform board 4a. A lifting rod 4b and a rack 4c are connected below the platform board 4a. A gear 4d driven by a motor is arranged below the rack 4c. The height by which the lifting rod 4b drives the platform board 4a to descend is 0.5 mm to 130 mm. An upper position induction switch 4e and a lower position induction switch 4f are arranged on the side surface of the platform board 4a. When the platform board 4a moves down to the position detection point of the lower position induction switch 4f, the motor drives the gear 4d to rotate, so that the rack 4c drives the platform board 4a to translate. The upper surface of the platform board 4a is used to place a tray, and the tray is used to stack the cut fiberglass felt sheets in layers.

[0030] Safety protection gratings are arranged on both sides of the mobile platform 4. The safety protection grating usually consists of two parts: a transmitter and a receiver. The transmitter is responsible for emitting infrared light beams or laser beams, while the receiver is responsible for receiving these beams and judging whether there is an object blocking or reflecting the beams, so as to detect and prevent personnel or objects from entering the active dangerous area of the unit mobile platform 4 and ensure the safe operation of the production line.

[0031] When the fully automatic fiberglass felt cutting machine disclosed by the utility model is in use, first place a tray on the mobile platform 4. Slide rails for supporting its translational movement are arranged below both the platform board 4a and the felt pulling mechanism 2. In order to achieve deviation correction during feeding (fiberglass felt roll), the air shaft 1a-2 is connected with a deviation correction electric cylinder 1a-3. The deviation correction electric cylinder 1a-3 drives the air shaft 1a-2 to move horizontally axially on the slide rail. An ultrasonic sensor 7 is arranged on the bracket of the fixed tension roller 1b. The ultrasonic sensor 7 is located on the side where the fiberglass felt moves. The ultrasonic sensor 7 measures the distance from the edge of the fiberglass felt to it, and adjusts the telescopic movement of the deviation correction electric cylinder 1a-3 according to the value, and moves the coiling felt roller 1a left and right to achieve deviation correction. The adjustment accuracy of the left and right deviation correction electric cylinders 1a-3 during unwinding is ±0.2 mm, which is better than the average control accuracy of ±0.5 mm in the industry, making the edges of multiple layers of fiberglass felt flush during transportation and the edges of the cut finished products neat when stacked together; when the mobile platform 4 receives materials (cut sheet fiberglass felt) below the felt pulling mechanism 2, the height of its top surface platform slowly descends, and the cut fiberglass felt is stacked layer by layer on it. When a certain amount (height) of fiberglass felt is loaded, the mobile platform 4 moves outwards horizontally to transport several cut and stacked fiberglass felt sheets away.

[0032] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. It should be noted that for those of ordinary skill in the art, any changes, modifications or additions made without departing from the concept of the utility model shall fall within the protection scope of the utility model.
