Description

Technical Field

[0001] This utility model relates to the field of PVC sheet cutting, specifically an intelligent PVC sheet laser cutting device. Background Technology

[0002] PVC sheets, or polyvinyl chloride sheets, are polymer sheets made from vinyl chloride monomer (VCM) polymerized under the action of an initiator or photothermal radiation via a free radical polymerization mechanism. Cutting is a crucial step in the installation of PVC sheets. It not only ensures a perfect fit between the floor and the ground but also helps to manage expansion joints between floorboards, improving the flatness and aesthetics of the floor.

[0003] In existing technologies, PVC sheets are typically cut before use to the required size. Laser cutting is commonly used to cut PVC sheets, which not only produces relatively flat sides but also reduces dust generation. However, when laser cutting PVC sheets, the entire sheet is usually placed on a cutting table. After cutting, the smaller pieces and finished sheets need to be removed one by one before placing and cutting the new whole sheet. This significantly increases the time required for cutting smaller pieces and reduces the efficiency of cutting PVC sheets. Utility Model Content

[0004] To overcome the shortcomings of existing technology, after PVC sheets are cut, the small pieces and finished sheets need to be removed one by one before placing and cutting the new whole sheet. This not only greatly increases the time required for cutting small pieces of sheet, but also reduces the efficiency of cutting PVC sheets. This utility model proposes an intelligent laser cutting device for PVC sheets.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an intelligent PVC sheet laser cutting device, including a mounting base, a movable stage fixedly connected to the surface of the mounting base, a laser cutting head body fixedly connected to the inner cavity of the movable stage, a control switch fixedly connected to one side of the movable stage, a PLC controller fixedly connected to one side of the mounting base, a servo motor fixedly connected to one side of the mounting base, and an alternating mechanism provided in the inner cavity of the mounting base;

[0006] The alternating mechanism includes a fixed plate, one side of which is fixedly connected to the inner cavity of the mounting base. A sliding plate is slidably connected to the top of the fixed plate, and a lifting plate is slidably connected to the inner cavity of the sliding plate. A second cutting table is fixedly connected to the top of the lifting plate. A sliding groove is formed on one side of the fixed plate, and a sliding rod is rotatably connected to one side of the lifting plate. The surface of the sliding rod is slidably connected to the inner cavity of the sliding groove. A first cutting table is slidably connected to the top of the mounting base. A first toothed plate is fixedly connected to the top of the sliding plate, and a second toothed plate is fixedly connected to the bottom of the first cutting table. A drive assembly is rotatably connected to one side of the mounting base, and a driven gear is fixedly connected to one side of the drive assembly. The teeth of the driven gear mesh with the teeth of the first and second toothed plates.

[0007] Preferably, the drive assembly includes a transmission rod, one end of which is fixedly connected to one side of the driven gear, the other end of which passes through the mounting base, a drive gear is fixedly connected to the surface of the transmission rod, a gear chain is drivenly connected to the surface of the drive gear, and the output end of the servo motor is fixedly connected to one side of the drive gear.

[0008] Preferably, a limiting ring block is fixedly connected to the inner cavity of the drive gear, and a limiting groove is formed on the surface of the transmission rod, with the surface of the limiting ring block fixedly connected to the inner cavity of the limiting groove.

[0009] Preferably, a limiting rod is fixedly connected to the bottom of the second cutting table, and the surface of the limiting rod is slidably connected to the inner cavity of the slide plate.

[0010] Preferably, a mounting block is fixedly connected to the bottom of the slide plate, and a spring is fixedly connected to the inner cavity of the mounting block. One end of the spring is fixedly connected to the bottom of the second cutting table.

[0011] Preferably, the top of the second cutting table and the first cutting table are provided with slots, and the top of the first cutting table and the second cutting table are movably inserted with placement plates.

[0012] Preferably, a slide rail is fixedly connected to the top of the mounting base, and a slider is fixedly connected to the bottom of the first cutting table, with the inner cavity of the slider slidably connected to the surface of the slide rail.

[0013] The advantages of this utility model are:

[0014] 1. In this device, the moving stage and the laser cutting head are controlled by a control switch to cut the PVC sheet placed inside the placement plate. After the sheet is cut, the first and second cutting stages can be moved towards each other by the operation of the servo motor. After the positions of the second and first cutting stages are interchanged, the new sheet can be cut while the cut sheet is being fed, reducing the impact of feeding the new sheet on the cutting of the PVC sheet.

[0026] 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 scope of protection of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0028] This application discloses an intelligent laser cutting device for PVC sheets. (Refer to...) Figure 1 and Figure 8 An intelligent PVC sheet laser cutting device includes a mounting base 1, a movable stage 2 fixedly connected to the surface of the mounting base 1, a laser cutting head body 3 fixedly connected to the inner cavity of the movable stage 2, a control switch 4 fixedly connected to one side of the movable stage 2, a PLC controller 5 fixedly connected to one side of the mounting base 1, a servo motor 6 fixedly connected to one side of the mounting base 1, and an alternating mechanism 7 provided in the inner cavity of the mounting base 1.

[0029] The alternating mechanism 7 includes a fixed plate 701, one side of which is fixedly connected to the inner cavity of the mounting base 1. A slide plate 702 is slidably connected to the top of the fixed plate 701. A lifting plate 703 is slidably connected to the inner cavity of the slide plate 702. A second cutting table 711 is fixedly connected to the top of the lifting plate 703. A slide groove 704 is provided on one side of the fixed plate 701. A slide rod 705 is rotatably connected to one side of the lifting plate 703. The surface of the slide rod 705 is slidably connected to the inner cavity of the slide groove 704. A first cutting table 708 is slidably connected to the top of the mounting base 1. A first toothed plate 706 is fixedly connected to the top of the slide plate 702. A second toothed plate 707 is fixedly connected to the bottom of the first cutting table 708. A drive assembly 709 is rotatably connected to one side of the mounting base 1. A driven gear 710 is fixedly connected to one side of the drive assembly 709. The teeth of the driven gear 710 mesh with the teeth of the first toothed plate 706 and the second toothed plate 707.

[0030] The drive assembly 709 includes a transmission rod 7091, one end of which is fixedly connected to one side of the driven gear 710. One end of the transmission rod 7091 passes through the mounting base 1. A drive gear 7092 is fixedly connected to the surface of the transmission rod 7091. A gear chain 7093 is drivenly connected to the surface of the drive gear 7092. The output end of the servo motor 6 is fixedly connected to one side of the drive gear 7092.

[0031] The mounting base 1 enables the installation of the movable stage 2 and the laser cutting head body 3. The movable stage 2 drives the laser cutting head body 3 to move, and the laser cutting head body 3 can cut PVC sheets. The control switch 4 controls the movable stage 2 and the laser cutting head body 3. The control switch 4 can also control the operation of the servo motor 6 via the PLC controller 5. The movable stage 2, the laser cutting head body 3, and the control switch 4 are existing technologies in this field. The fixed plate 701 is connected to the lifting plate 703 via the sliding plate 702. The slide groove 704 connected to one side of the lifting plate 703 can slide inside the slide rod 705. Simultaneously, the middle section of the slide rod 705, when sliding inside the slide groove 704, can drive the sliding plate 702 to slide on top of the fixed plate 701 via the lifting plate 703. Since the top of the lifting plate 703 is connected to the second cutting table 711, when the lifting plate 703 moves, it can drive the slide rod 705 to move. The second cutting table 711 moves in a sequence of translation, downward movement, upward movement, and translation again. While the sliding plate 702 moves, it also drives the first toothed plate 706 to move together. Because the first toothed plate 706 meshes with the driven gear 710, the driven gear 710 can smoothly drive the first toothed plate 706 to move when it rotates. Furthermore, because the second toothed plate 707 also meshes with the driven gear 710, while the first toothed plate 706 moves, the second toothed plate 707 can drive the first cutting table 708 towards the sliding plate. The second cutting table 711 moves downwards during the movement of the first cutting table 708, making it less likely for the second cutting table 711 and the first cutting table 708 to collide. When the servo motor 6 operates under the control of the PLC controller 5, it can drive the drive gear 7092 to rotate, thereby driving the driven gear 710 to rotate in the same direction through the transmission rod 7091 and the gear chain 7093. At the same time, the number of transmission rod 7091, drive gear 7092 and driven gear 710 is the same.

[0032] Reference Figure 4 and Figure 8 The inner cavity of the drive gear 7092 is fixedly connected to the limiting ring block 16, and the surface of the transmission rod 7091 is provided with a limiting groove 15. The surface of the limiting ring block 16 is fixedly connected to the inner cavity of the limiting groove 15. The fixed connection between the limiting ring block 16 and the limiting groove 15 makes it possible for the drive gear 7092 to drive the transmission rod 7091 to rotate more stably when it rotates, and makes it less likely for the transmission rod 7091 and the drive gear 7092 to shake or become unstable when they are synchronized.

[0033] Reference Figure 5 and Figure 6The bottom of the second cutting table 711 is fixedly connected to a limiting rod 11. The surface of the limiting rod 11 is slidably connected to the inner cavity of the slide plate 702. The setting of the limiting rod 11 ensures that when the lifting plate 703 moves and drives the second cutting table 711 to move up and down, the up and down movement of the second cutting table 711 is stable enough and it is not easy for it to tilt or shake during the up and down movement, thus increasing the stability of the second cutting table 711 during use.

[0034] Reference Figure 3 A mounting block 13 is fixedly connected to the bottom of the slide plate 702. A spring 12 is fixedly connected to the inner cavity of the mounting block 13. One end of the spring 12 is fixedly connected to the bottom of the second cutting table 711. The slide plate 702 can install and fix the spring 12 through the mounting block 13. The setting of the spring 12 allows the second cutting table 711 to compress the spring 12 when it moves down, up, or back up during the process of translation. This makes it easier for the second cutting table 711 to reset by moving up when it needs to reset.

[0035] Reference Figure 2 and Figure 6 The top of the second cutting table 711 and the first cutting table 708 are provided with slots 10. The top of the first cutting table 708 and the second cutting table 711 are movably connected with placement plates 8. The bottom of the placement plate 8 is fixedly connected with a plug plate 9. The surface of the plug plate 9 is movably connected to the inner cavity of the slot 10. The placement plate 8 can be used to place the PVC sheet to be cut. The placement plate 8 can be easily removed from the top of the second cutting table 711 or the first cutting table 708 through the setting of the plug plate 9 and the slot 10. This allows the placement plate 8 to be removed from the top of the second cutting table 711 or the first cutting table 708 when the operator needs to remove the cut sheet. The placement plate 8 containing the whole PVC sheet can be placed on the top of the second cutting table 711 or the first cutting table 708 first. Then the small pieces of PVC can be taken out and unloaded. This makes it less likely to affect the cutting efficiency of the laser cutting head body 3 when the operator unloads and removes the cut PVC sheet.

[0036] Reference Figure 2 and Figure 3 The top of the mounting base 1 is fixedly connected to a slide rail 17, and the bottom of the first cutting table 708 is fixedly connected to a slider 14. The inner cavity of the slider 14 is slidably connected to the surface of the slide rail 17. The arrangement of the slider 14 and the slide rail 17 ensures that the movement of the first cutting table 708 is stable enough when it is slid and translated by the second toothed plate 707, and it is not easy for it to shake or deviate.

[0037] Working principle: When using this device, the operator can place the PVC sheet to be cut onto the placement plate 8 on top of the first cutting table 708 and the second cutting table 711. Then, the laser cutting head body 3 can be started by the control switch 4 to cut the sheet placed on top of the first cutting table 708. After cutting is completed, the control switch 4 can start the servo motor 6 through the PLC controller 5, so that the servo motor 6 can operate. When the servo motor 6 is operating, it can drive one of the drive gears 7. 092 drives the gear chain 7093 for transmission, enabling the drive gear 7092 to smoothly drive the driven gear 710 to rotate via the transmission rod 7091. When the driven gear 710 rotates, it meshes with the first gear plate 706 and the second gear plate 707, causing the first gear plate 706 and the second gear plate 707 to move in opposite directions. The movement of the second gear plate 707 causes the first cutting table 708 to translate. Meanwhile, when the first gear plate 706 drives the slide plate 702 to move, the slide plate 702... The lifting plate 703 drives the sliding rod 705 to slide within the inner cavity of the slide groove 704. Because the middle part of the slide groove 704 is lower than the two sides, the lifting plate 703 will drive the second cutting table 711 to move horizontally, downward, upward, and horizontally again during its movement. During the downward and upward movements, the second cutting table 711 will reduce the possibility of collision with the first cutting table 708 when moving towards each other. After the second cutting table 711 returns to its original position after moving upward, when it moves horizontally again, it will move to the original position of the first cutting table 708. At the position of the cutting table 708, the operator can then unload the PVC sheet cut from the top of the first cutting table 708. At the same time, the laser cutting head body 3 and the moving table 2 can cut the sheet from the top of the first cutting table 708. This ensures that when the operator is unloading the cut PVC sheet, it does not affect the working efficiency of the moving table 2 and the laser cutting head body 3. When the cut PVC sheet is being unloaded, the moving table 2 and the laser cutting head body 3 can continue to cut the PVC sheet.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
