[0005] The purpose of this invention is to provide a quantitative fiberglass cloth cutting device to solve the problem mentioned in the background art that the quantitative fiberglass cloth cutting device does not fix and limit the fiberglass cloth around the cutter head during operation, which leads to the fiberglass cloth easily shifting during cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fiberglass cloth quantitative cutting device includes a conveyor frame and further includes: The processing stand is mounted on the conveyor frame; The lifting seat has a movable groove at the bottom of the processing seat, and the lifting seat is movably disposed in the movable groove and configured to move in a direction perpendicular to the conveyor frame. The cutter head is located at the bottom of the lifting base; The power source is installed on the machining base. The power shaft of the power source is connected to the lifting base and is used to drive the lifting base to move. Two drive seats are located at the bottom of the lifting seat and on both sides of the cutter head; The leveling mechanism is mounted on the drive unit; The lifting seat is configured such that when it moves downward under the drive of the power source, the driving leveling mechanism contacts and unfolds laterally before the cutter head to flatten the fiberglass cloth, and then the cutter head cuts the flattened fiberglass cloth.

[0007] In one embodiment, the leveling mechanism includes a lateral leveling head and a transmission assembly; The bottom of the drive seat is provided with a mounting groove, and the horizontal leveling head is horizontally movable and is arranged in the receiving groove, with its bottom extending out of the mounting groove. The transmission assembly is connected between the lifting seat and the horizontal leveling head, and is configured to convert the vertical movement of the lifting seat into the horizontal movement of the horizontal leveling head, driving the two horizontal leveling heads to move away from each other after contacting the fiberglass cloth.

[0008] In one embodiment, the transmission assembly includes: The lead screw is rotatably mounted in the mounting slot and is threadedly connected to the transverse flattening head. The gear is fixedly mounted on the lead screw; The rack is fixedly mounted on the lifting seat and meshes with the gear; When the lifting seat moves downward, the drive seat moves upward relative to the lifting seat, causing the gear to roll along the rack and drive the lead screw to rotate, thus driving the horizontal leveling head to move horizontally.

[0009] In one embodiment, the drive seat is connected to the lifting seat via a first elastic element, which provides buffering and restoring force for the upward movement of the drive seat relative to the lifting seat.

[0010] In one embodiment, the bottom of the lifting seat is provided with a movable groove, the drive seat is installed in the movable groove, one end of the first elastic member is installed on the inner wall of the movable groove, and the other end is installed on the drive seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the cooperation of the lifting seat and the leveling mechanism, allows for pre-treatment of the fiberglass cloth before the cutter head cuts, preventing the cutter head from directly contacting the unleveled fiberglass cloth. The cooperation between the transverse leveling head and the transmission assembly stabilizes the vertical movement of the lifting seat into the horizontal movement of the transverse leveling head, driving the two transverse leveling heads to move away from each other after contact with the fiberglass cloth, applying symmetrical transverse tension to the fiberglass cloth on both sides of the cutter head. The combination of the longitudinal leveling head at the bottom of the transverse leveling head and the third elastic element allows the longitudinal leveling head to continuously adhere to the surface of the fiberglass cloth under the elastic force of the third elastic element, compacting the material along the fiberglass cloth conveying direction.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 A quantitative cutting device for fiberglass cloth includes a conveyor frame 100, and further includes: A processing base 200 is mounted on the conveyor frame 100; The lifting seat 300 has a moving groove 201 at the bottom of the processing seat 200. The lifting seat 300 is movably disposed in the moving groove 201 and is configured to move in a direction perpendicular to the conveyor frame 100. The cutter head 400 is located at the bottom of the lifting base 300; Power source 202 is installed on processing base 200. The power shaft of power source 202 is connected to lifting base 300 and is used to drive lifting base 300 to move. Two drive seats 500 are disposed at the bottom of the lifting seat 300 and located on both sides of the cutter head 400; The leveling mechanism is mounted on the drive base 500; The lifting seat 300 is configured such that when it moves downward under the drive of the power source 202, the driving leveling mechanism first contacts and unfolds laterally before the cutter head 400 to lay out the fiberglass cloth, and then the cutter head 400 cuts the laid-out fiberglass cloth.

[0025] In the above technical solution, the leveling and cutting actions are linked by the vertical movement of the lifting seat 300. The processing seat 200 provides a guiding foundation for the vertical movement of the lifting seat 300. When the power source 202 drives the lifting seat 300 to move vertically downward along the moving groove 201, the leveling mechanism is set on the drive seats 500 on both sides of the cutter head 400. The initial installation position of the leveling mechanism causes it to contact the fiberglass cloth on the conveyor frame 100 before the cutter head 400. As the lifting seat 300 continues to move downward, the drive seats 500 move vertically synchronously with the lifting seat 300, driving the leveling mechanism to generate a lateral unfolding motion, stretching and flattening the fiberglass cloth around the cutter head 400 to both sides, ensuring that the fiberglass cloth is in a flat and stable state before the cutter head 400 contacts it. After the leveling action is completed, the lifting seat 300 continues to move downward so that the cutter head 400 contacts the flattened fiberglass cloth, and finally completes the quantitative cutting.

[0026] In one embodiment, the leveling mechanism includes a transverse leveling head 501 and a transmission assembly; The bottom of the drive seat 500 is provided with a mounting groove 505, and the horizontal leveling head 501 is horizontally movable and disposed in the receiving groove, with its bottom extending out of the mounting groove 505. The transmission assembly is connected between the lifting seat 300 and the horizontal leveling head 501, and is configured to convert the vertical movement of the lifting seat 300 into the horizontal movement of the horizontal leveling head 501, driving the two horizontal leveling heads 501 to move away from each other after contacting the fiberglass cloth.

[0027] In the above technical solution, the mounting groove 505 at the bottom of the drive seat 500 provides a guide space for the horizontal movement of the horizontal leveling head 501, ensuring that the leveling head can only move in the preset horizontal direction; when the lifting seat 300 moves vertically downward under the drive of the power source 202, the transmission component, as a motion conversion medium, converts the vertical displacement of the lifting seat 300 into the horizontal driving force of the horizontal leveling head 501.

[0028] Specifically, the lifting seat 300 moves down, causing the drive seat 500 to move vertically in sync. Under the action of this vertical movement, the transmission component causes the transverse leveling head 501 to move horizontally along the inner wall of the mounting groove 505. Since the two drive seats 500 are located on both sides of the cutter head 400, the symmetrical design of the transmission component causes the two transverse leveling heads 501 to move away from each other. When the bottom of the transverse leveling head 501 contacts the fiberglass cloth, the continuous horizontal movement will apply a tensile force to both sides to the fiberglass cloth, flattening and tightening the fiberglass cloth in the area to be cut around the cutter head 400 until the lifting seat 300 moves down until the cutter head 400 contacts the fiberglass cloth to complete the cutting.

[0029] In one embodiment, the transmission assembly includes: The lead screw 502 is rotatably mounted in the mounting groove 505 and threadedly connected to the transverse leveling head 501; Gear 503 is fixedly mounted on lead screw 502; The rack 504 is fixedly mounted on the lifting seat 300 and meshes with the gear 503; When the lifting seat 300 moves downward, the drive seat 500 moves upward relative to the lifting seat 300, causing the gear 503 to roll along the rack 504 and drive the lead screw 502 to rotate, driving the transverse leveling head 501 to move horizontally.

[0030] In the above technical solution, the rack 504 is fixed to the lifting seat 300, providing a meshing reference for the gear 503. The lead screw 502 is rotatably installed in the mounting groove 505 of the drive seat 500 and forms a threaded pair with the transverse leveling head 501. The gear 503 and the lead screw 502 are fixedly connected to achieve synchronous movement. When the lifting seat 300 moves downward under the drive of the power source 202, the transverse leveling head 501 first contacts the fiberglass cloth and receives a supporting reaction force, preventing the drive seat 500 from continuing to move downward with the lifting seat 300, thus forming a relative displacement of the drive seat 500 relative to the lifting seat 300 moving upward. During this process, the gear 503 moves upward with the drive seat 500. The blade 400 moves upward and is forced to roll and rotate due to its engagement with the fixed rack 504. This rotational motion is transmitted to the transverse leveling head 501 through the lead screw 502. With the help of the threaded engagement between the lead screw 502 and the transverse leveling head 501, the rotational motion is converted into the horizontal linear motion of the transverse leveling head 501 along the mounting groove 505. Since the two drive seats 500 are symmetrically distributed on both sides of the blade 400 and the helical directions of the two lead screws 502 are opposite, the two transverse leveling heads 501 form a tendency to move away from each other under the drive of relative motion, applying symmetrical transverse tension to the fiberglass cloth around the blade 400 to achieve a leveling effect.

[0031] In one embodiment, the drive seat 500 is connected to the lifting seat 300 via a first elastic element 302, which provides buffering and restoring force for the upward movement of the drive seat 500 relative to the lifting seat 300.

[0032] In one embodiment, the bottom of the lifting seat 300 is provided with a movable groove 301, the drive seat 500 is installed in the movable groove 301, one end of the first elastic member 302 is installed on the inner wall of the movable groove 301, and the other end is installed on the drive seat 500.

[0033] Specifically, the first elastic element 302 is a compression spring, or a spring block; the movable groove 301 provides the drive seat 500 with vertical movement space and guiding constraints, allowing the drive seat 500 to move only up and down along the inner wall of the movable groove 301, avoiding lateral deviation; when the lifting seat 300 moves downward and the lateral leveling head 501 contacts the fiberglass cloth, the drive seat 500 is hindered by the supporting force of the fiberglass cloth and cannot continue to move downward. At this time, the continuous downward movement of the lifting seat 300 causes the drive seat 500 to move upward relative to the lifting seat 300, compressing the first elastic element 302 installed between the inner wall of the movable groove 301 and the drive seat 500. The elastic element generates an upward elastic force due to deformation. This elastic force buffers the relative motion impact between the drive seat 500 and the lifting seat 300 on the one hand, and forms a resistance opposite to the direction of relative motion on the other hand, so that the horizontal movement speed of the transverse leveling head 501 gradually and smoothly changes with the elastic deformation. When the cutting is completed and the lifting seat 300 moves upward, the deformation of the first elastic element 302 is restored, and the elastic force pushes the drive seat 500 to move downward along the movable groove 301 until it is reset to the initial position, ensuring that the transverse leveling head 501 is disengaged from the fiberglass cloth and returns to the starting state of the next action, through the cooperation of the elastic element and the movable groove 301.

[0034] In one embodiment, the cutter head 400 is connected to the lifting seat 300 via a second elastic element 401, so that the cutter head 400 can perform buffered extension and retraction relative to the lifting seat 300 during the process of the leveling mechanism laying the fiberglass cloth.

[0035] In one embodiment, the bottom of the lifting seat 300 is provided with a fixing groove, and the cutter head 400 and the second elastic member 401 are disposed in the fixing groove. One end of the second elastic member 401 is installed on the cutter head 400, and the other end is installed on the inner wall of the fixing groove.

[0036] In one embodiment, the power shaft of the power source 202 is connected to the cutter head 400.

[0037] Specifically, the power source 202 can be a cylinder or a linear motor. When the power source 202 drives the cutter head 400 to move downward, it will drive the lifting seat 300 to move downward simultaneously under the compression force of the second elastic element 401. After the horizontal leveling head 501 flattens the fiberglass cloth, when the power source 202 continues to drive the cutter head 400 to move downward, the force it applies will be greater than the elastic force of the second elastic element 401, so that the power source 202 drives the cutter head 400 to cut the fiberglass cloth.

[0038] In a preferred embodiment, the bottom of the transverse leveling head 501 has two grooves, and a longitudinal leveling head 506 is installed in each of the two grooves, with the bottom end of the longitudinal leveling head 506 extending out of the groove.

[0039] In a preferred embodiment, a third elastic element 507 is installed on the inner wall of the groove, and the third elastic element 507 is connected to the longitudinal flattening head 506.

[0040] Specifically, the third elastic element 507 is a spring-loaded spring, or a coil spring. The groove at the bottom of the transverse leveling head 501 provides installation and movement space for the longitudinal leveling head 506. One end of the third elastic element 507 is connected to the inner wall of the groove, and the other end is connected to the longitudinal leveling head 506. Utilizing the elastic energy storage characteristics of the spring-loaded spring or coil spring, it provides continuous downward pressure to the longitudinal leveling head 506. When the transverse leveling head 501 moves down with the drive seat 500 and contacts the fiberglass cloth, the longitudinal leveling head 506 contacts the fiberglass cloth before or simultaneously. The third elastic element 507, due to the longitudinal... The supporting reaction force on the leveling head 506 causes deformation, generating an elastic force matching the degree of deformation, so that the longitudinal leveling head 506 always adheres to the surface of the fiberglass cloth with appropriate pressure. During the process of the transverse leveling head 501 moving laterally to flatten the fiberglass cloth, the longitudinal leveling head 506, under the action of the third elastic element 507, maintains a compacted state along the conveying direction of the fiberglass cloth, stretching and smoothing the loose fibers in the conveying direction, forming a cross-fixation with the transverse tension of the transverse leveling head 501, structurally ensuring that the fiberglass cloth around the cutter head 400 is stably limited in both longitudinal and transverse directions.

[0041] The working principle and usage process of this utility model are as follows: After the power source 202 is started, the driving lifting seat 300 moves vertically downward along the moving groove 201 of the processing seat 200. Since the initial position of the transverse leveling head 501 is lower than the cutter head 400, the transverse leveling head 501 first contacts the fiberglass cloth on the conveyor frame 100. At the same time, the longitudinal leveling head 506 at the bottom of the transverse leveling head 501 is synchronously attached to the fiberglass cloth under the action of the third elastic element 507. The third elastic element 507 deforms due to the supporting reaction force and provides continuous adhesion pressure to the longitudinal leveling head 506. As the lifting seat 300 continues to move downward, the transverse leveling head 501... 01 Due to the obstruction of the fiberglass cloth's supporting force, the drive seat 500 cannot move down synchronously with the lifting seat 300. Instead, the drive seat 500 moves upward relative to the lifting seat 300 along the movable groove 301 and compresses the first elastic element 302. During this process, the gear 503 on the drive seat 500 moves upward with the drive seat 500, meshing and rolling with the rack 504 fixed on the lifting seat 300, driving the lead screw 502 to rotate. The lead screw 502 converts the rotational motion into the horizontal motion of the horizontal leveling head 501 through its threaded engagement with the horizontal leveling head 501. Because the lead screws 502 on the two drive seats 500 rotate... Conversely, the two transverse leveling heads 501 move away from each other and apply transverse tension to the fiberglass cloth. At the same time, the longitudinal leveling head 506, under the action of the third elastic element 507, maintains a compacted state along the fiberglass cloth conveying direction, stretching and smoothing the loose fibers in the conveying direction, thus achieving bidirectional flattening of the fiberglass cloth. After the fiberglass cloth is flattened, the power source 202 continues to output power, and the force it applies is greater than the elastic force of the second elastic element 401, causing the cutter head 400 to extend from the fixed groove of the lifting seat 300 and contact the flattened fiberglass cloth, completing the quantitative cutting. After the cutting is completed, the power source 202 drives the lifting seat 300 to return to its original position. The first elastic element 302 restores its deformation and pushes the drive seat 500 to reset downward along the movable groove 301. The gear 503 moves downward with the drive seat 500 and rolls in the opposite direction, causing the lead screw 502 to reverse, so that the two transverse leveling heads 501 move closer to each other and reset. The longitudinal leveling head 506 disengages from the fiberglass cloth along with the transverse leveling head 501. The third elastic element 507 restores its deformation, and at the same time, the second elastic element 401 pushes the cutter head 400 back into the fixed groove. The entire equipment returns to its initial state and waits for the next cutting cycle. The conveyor frame 100 can control the conveying distance of the fiberglass cloth each time, thereby realizing the quantitative cutting of the fiberglass cloth.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
