Description

Technical Field

[0001] The invention relates to the technical field of glass fiber processing equipment, and in particular discloses a glass fiber neat short chopping machine. Background Art

[0002] The recycling of glass fiber is an important way to achieve resource recycling, environmental protection and economic development. In the process of glass fiber recycling, the glass fiber in packages is first put into a liquid tank to soak for a period of time to soften it, and then put into a vibrating centrifuge for dehydration. After dehydration, it is cut into short strands required by customers by a short cutter. The glass fiber short cutter is needed in the short strand processing process.

[0003] At present, the existing glass fiber short cutting machine is mainly composed of a conveyor belt, a cutting knife, a pressure roller and other components. The glass fiber material after centrifugal dehydration is sent to the pressure roller by the conveyor belt, and then sent to the bottom of the cutting knife for cutting by the pressure roller. For example, the utility model patent with application number 2023216329899 discloses a glass fiber waste chopped short production line, including a cutter, a vibrating feeder, a first conveying device, a rolling cutter, a first vibrating screen, a second conveying device, a second vibrating screen, a third conveying device and a fourth conveying device. A vibrating feeder is arranged on one side of the cutter, and the vibrating feeder is connected to the rolling cutter through the first conveying device. A first vibrating screen is arranged below the rolling cutter, and a small particle outlet of the first vibrating screen is connected to the second vibrating screen through the second conveying device, and a small particle outlet of the second vibrating screen is connected to a dryer through a fifth conveying device, and large particle outlets of the first vibrating screen and the second vibrating screen are connected to the vibrating feeder through the third conveying device and the fourth conveying device respectively; the cutter in the glass fiber waste chopped short production line is a traditional glass fiber chopped short machine. When it is used for cutting glass fiber recycled materials, since not all glass fibers are perpendicular to the cutting knife, some glass fiber fibers are clamped less than 30° with the cutting knife during the cutting process, resulting in the glass fiber short materials being too long after cutting, requiring secondary cutting processing. Therefore, in view of the technical problems existing in the existing glass fiber chopping machine used in the cutting process of glass fiber recycled materials, the present application proposes a glass fiber neat chopping machine that can effectively solve the technical problems. Summary of the invention

[0004] The present invention aims to provide a glass fiber neat short chopping machine to solve the technical problems existing in the existing glass fiber short chopping machine used in the cutting process of glass fiber recycled materials.

[0005] The present invention is achieved through the following technical solutions: A glass fiber neat short chopping machine comprises a conveying unit and a cutting unit, wherein the cutting unit is arranged directly above one end of the conveying unit, a combing unit is arranged directly above the conveying unit, and a step-feeding unit is arranged between the conveying unit and the cutting unit; The combing unit comprises a combing frame rotatably arranged with the cutting unit at one end, a horizontal support assembly is arranged between the other end of the combing frame and the conveying unit, a closed-loop transmission member parallel to the conveying unit is arranged in the combing frame, a plurality of combing strips are vertically connected at equal intervals on the closed-loop transmission member, and a row of combing teeth acting on the glass fibers on the conveying unit are arranged on the combing strips; The step-by-step feeding unit comprises an upper bite roller and a lower bite roller which are arranged to rotate synchronously in opposite directions, and the roller gap between the upper bite roller and the lower bite roller is flush with the upper end of the conveying unit. The upper bite roller, the lower bite roller and the cutting unit are connected by a gap transmission mechanism.

[0006] As a further configuration of the above scheme, the cutting unit includes a bracket arranged directly above the end of the conveying unit, a rotating shaft is rotatably arranged in the bracket, a cutting motor is connected to the end of the rotating shaft, a cam is arranged on the rotating shaft, a cutting knife is arranged below the rotating shaft, an extrusion roller acting with the cam is arranged at the upper end of the cutting knife, and a guiding elastic component is arranged between the side end of the cutting knife and the bracket.

[0007] As a further configuration of the above scheme, the guide elastic component includes a protrusion arranged at the side end of the cutting knife, the protrusion is provided with a guide column and a spring, a guide block is provided on the side wall of the bracket, and a through hole for passing the guide column is opened on the guide block, and both ends of the spring are connected to the guide block and the protrusion.

[0008] As a further configuration of the above scheme, a cutting board aligned vertically with the cutting knife is provided at the end of the conveying unit, and a material discharge guide plate is provided on the bottom box below the cutting board.

[0009] As a further arrangement of the above scheme, the intermittent transmission mechanism includes a notched wheel arranged at the end of the rotating shaft and a groove wheel arranged at the end of the upper biting roller, a plurality of shifting grooves are evenly arranged on the groove wheel, a shifting bar is radially extended at the notch of the notched wheel, and a shifting protrusion that acts on the shifting groove is arranged at the end of the shifting bar, and gears that mesh with each other are arranged on the roller shafts of the upper biting roller and the lower biting roller.

[0010] As a further configuration of the above scheme, the conveying unit includes a bottom box, a conveying seat is arranged at the upper end of the bottom box, and a conveying belt for conveying glass fibers is arranged in the conveying seat.

[0011] As a further configuration of the above scheme, the horizontal support assembly includes support rods connected to the front and rear sides of the combing frame, the bottom box is provided with a support block that interacts with the support rods, the bottom box is provided with a hydraulic telescopic rod for driving the combing frame to lift, or a handle is provided on the combing frame.

[0012] As a further configuration of the above scheme, wheel axles are rotatably arranged at both ends of the combing frame, and one end of the wheel axles is connected to a combing motor, a transmission wheel is arranged on the wheel axle, and the closed-loop transmission member is arranged between the two transmission wheels aligned on the left and right.

[0013] As a further configuration of the above solution, the closed-loop transmission member is one of a chain or a transmission belt.

[0014] During use of the glass fiber neat short cutting machine disclosed in the present invention, the combing unit is first lifted manually or by a hydraulic telescopic rod, and then the operator lays the glass fiber to be cut on the conveyor belt in the conveying unit, and then the conveyor belt conveys the glass fiber to the roller gap between the upper bite roller and the lower bite roller until the end of the glass fiber is bitten by the two rollers, and then the combing unit is lowered to a horizontal level after biting.

[0015] Before and during the front end process of glass fiber cutting, the combing motor is started to make the lower end of the closed-loop transmission member continuously move away from the cutting unit, and the combing strip will move synchronously under the action of the closed-loop transmission member. During the movement of the combing strip, the combing teeth at the bottom can comb the glass fibers on the upper surface of the conveyor belt in the same direction, so that the direction of the glass fibers before cutting is consistent and neat.

[0016] During the cutting process, the cutting motor drives the shaft to rotate at a certain speed, and then the cutting knife is pressed down by the action between the cam and the extrusion roller, and the glass fiber is cut by the shearing action between the blade at the bottom of the cutting knife and the knife anvil during the pressing process. After cutting, the cutting knife will rise and reset under the action of the spring. After resetting, the glass fiber will be transported to a certain length by the action of the upper and lower bite rollers before cutting. During the operation of the upper and lower bite rollers, due to the action between the notched wheel and the groove wheel, the upper bite roller will rotate a certain angle every time the shaft rotates one circle, and then the lower bite roller can be synchronously rotated in the opposite direction by the meshing transmission of the gears. Therefore, under the joint action of the upper and lower bite rollers, it is ensured that the glass fiber can be transported to the same length directly below the cutting knife after each cutting. Repeated cutting actions can cut the glass fiber neatly and at a fixed length at high speed, ensuring the product quality of the glass fiber after cutting.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The glass fiber neat short cutting machine disclosed in the present invention is designed with a combing unit and a step-by-step feeding unit. Before the glass fiber waste is cut, the step-by-step feeding unit first bites the end of the glass fiber conveyed, and then the combing strips and combing teeth in the combing unit can automatically comb the glass fiber to be perpendicular to the cutting knife, and then continuous cutting processing is performed, which effectively avoids the problem of inconsistent material length after cutting due to the glass fiber not being perpendicular to the cutting knife.

[0018] The step feeding unit in the present invention is connected with the cutting unit through an intermittent transmission mechanism, so that after the cutting knife is pressed down to cut each time, the intermittent transmission mechanism can make the upper bite roller and the lower bite roller synchronously rotate in the opposite direction by the same angle, thereby making the feeding length consistent after each cutting, and the effect of neatly combing the glass fiber before cutting can ensure that the length of the short glass fiber after the final cutting is basically consistent, thereby improving the product quality of the glass fiber short cutting processing.

At the same time, due to the meshing transmission between the two gears 503, the lower bite roller 502 will synchronously rotate in the opposite direction by a corresponding angle. Then, under the joint action of the upper bite roller 501 and the lower bite roller 502, the glass fiber material is transported to a certain length in the direction of the cutting knife 205 at a fixed distance. Repeating the above-mentioned actions can achieve continuous fixed-length cutting of the glass fiber material.
