A slitting device for pc sheet

Abstract

This utility model relates to the field of PC sheet processing technology, specifically a PC sheet slitting device, including an operating table with a PC sheet placement rack slidably connected to one side of the operating table. When the PC sheet is to be processed, a drive cylinder inside the fixed rack moves the support, which in turn moves the drive frame A. Positioning plates A and B at the bottom of the drive frame A contact the surface of the PC sheet, and springs at the ends of positioning plates A and B are compressed, fixing the PC sheet at the slitting point. The cutter on the drive frame A cuts the PC sheet. Simultaneously, when the cutter on the drive frame A is damaged, a servo motor A inside the support rotates the gear outside the support rod. The gear meshes with external symmetrical toothed plates, causing the two sets of toothed plates to move the drive frame A and drive frame B respectively. Consequently, drive frame A moves upward and drive frame B moves downward. The bottom structure of drive frame B is the same as that of drive frame A, facilitating cutter replacement and improving the slitting efficiency of the PC sheet.

Description

Technical Field

[0001] This utility model relates to the field of PC sheet processing technology, specifically to a PC sheet slitting device. Background Technology

[0002] PC sheets, or polycarbonate sheets, are a common type of plastic sheet. They have excellent performance and a wide range of applications. PC sheets are made from polycarbonate resin through processes such as extrusion, injection molding, extrusion, or calendering. They are characterized by excellent transparency, high temperature resistance, impact resistance, and chemical corrosion resistance, and are therefore widely used in construction, advertising, transportation, electronics, and other fields.

[0003] Patent No. 202022890882.7 discloses a cutting device for PC sheets, which can avoid the distortion of the cut during the processing of PC sheets and improve the processing accuracy.

[0004] However, existing PC sheet cutting devices use a working plate, pressure plate mechanism, and transmission mechanism to cut PC sheets. However, the two sides of the cutting part cannot be fixed during the cutting process, and the PC sheet is prone to displacement. In addition, if the cutting blade is damaged during use, the machine needs to be stopped and the blade needs to be disassembled and replaced. The operation is cumbersome and has a certain impact on the cutting efficiency of PC sheets. Therefore, a PC sheet cutting device is designed. Utility Model Content

[0005] In view of the problems in the background art, the present invention provides a PC sheet cutting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a PC sheet cutting device, including an operating table. A placement rack for placing PC sheets is slidably connected to one side of the operating table. A fixed frame is welded to the outside of the operating table, and a drive cylinder is bolted to the inside of the fixed frame. A bracket is bolted to the power output end of the drive cylinder. A servo motor A that provides power is bolted to the inside of the bracket, and a support rod is keyed to the power output end of the servo motor A. A gear is splined to the outside of the support rod. Drive frame A and drive frame B are symmetrically slidably connected to the outside of the bracket. Gear plates that mesh with gears are welded to the inside of drive frame A and drive frame B. Cutting blades for cutting PC sheets are screwed to the inside of drive frame A and drive frame B. Positioning plate A and positioning plate B are symmetrically slidably connected inside drive frame A, and springs are welded to the ends of positioning plate A and positioning plate B. Rubber pads are screwed to the outside of positioning plate A and positioning plate B.

[0007] By adopting the above technical solution, when PC sheet is to be cut, the drive cylinder in the fixed frame drives the bracket to move, and then the bracket drives the drive frame A to move, so that the positioning plate A and positioning plate B at the bottom of the drive frame A contact the surface of the PC sheet. Then the springs at the ends of positioning plate A and positioning plate B are compressed, and the elastic force generated by the spring drives positioning plate A and positioning plate B to press the PC sheet, so that the cutting part of the PC sheet is fixed. As positioning plate A and positioning plate B contract, the cutter on the drive frame A contacts the surface of the PC sheet, improving the cutting efficiency of the PC sheet. When the cutter on drive frame A is damaged, the servo motor A inside the bracket drives the support rod to rotate, and then the gear outside the support rod meshes with the external symmetrical toothed plates to move. This causes the two sets of toothed plates to drive drive frame A and drive frame B to move respectively. As a result, drive frame A moves up and drive frame B moves down. The bottom structure of drive frame B is the same as the bottom structure of drive frame A, which facilitates the replacement of the cutter and improves the cutting efficiency of PC sheets.

[0008] Specifically, the operating console is bolted to a servo motor B that provides power, and the power output end of the servo motor B is keyed to a threaded screw. A threaded block is threaded to the outside of the threaded screw, and the outside of the threaded block is welded to the bottom of the placement frame.

[0009] By adopting the above technical solution, when the position of the PC board on the placement rack needs to be adjusted, the servo motor B in the operating table drives the threaded screw to rotate, and the limiting sleeve symmetrically welded to the outside of the threaded block slides outside the limiting rod symmetrically welded to the inside of the operating table, so that the threaded block moves axially outside the threaded screw, and then the threaded block drives the placement rack to move, thereby facilitating the adjustment of the position of the PC board on the placement rack.

[0010] Specifically, the placement rack is internally bolted with a double-headed cylinder that provides power, and the power output end of the double-headed cylinder is symmetrically screwed with support plates A and B for fixing the PC sheet.

[0011] By adopting the above technical solution, when the PC sheet is placed on the placement rack, the double-headed cylinder inside the placement rack drives the support plate A and support plate B to move, and then the support plate A and support plate B come into contact with the surface of the PC sheet, thereby facilitating the fixing of the PC sheet.

[0012] Specifically, the support surface is symmetrically provided with limiting grooves, and the drive frame A and drive frame B are symmetrically welded with limiting blocks on their exteriors.

[0013] By adopting the above technical solution, when drive frame A and drive frame B move, the limiting blocks symmetrically welded to the outside of drive frame A and drive frame B slide in the limiting grooves symmetrically opened on the bracket, thereby facilitating the limiting of drive frame A and drive frame B and improving the stability of the movement of drive frame A and drive frame B.

[0014] Specifically, the dual-head cylinder, servo motor B, servo motor A, and the input terminal of the drive cylinder are all electrically connected to the power supply terminal of an external power source.

[0015] By adopting the above technical solution, the electrical equipment can operate normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0016] The beneficial effects of this utility model are: (1) The PC sheet cutting device of this utility model, when the PC sheet is to be cut, the drive cylinder in the fixed frame drives the support to move, and then the support drives the drive frame A to move, so that the positioning plate A and positioning plate B at the bottom of the drive frame A contact the surface of the PC sheet. Then the springs at the ends of the positioning plate A and positioning plate B are compressed, and the elastic force generated by the spring drives the positioning plate A and positioning plate B to press the PC sheet, so that the cutting part of the PC sheet is fixed. As the positioning plate A and positioning plate B contract, the cutter on the drive frame A contacts the surface of the PC sheet, thereby improving the cutting efficiency of the PC sheet.

[0017] (2) In the PC sheet cutting device described in this utility model, when the cutter on the drive frame A is damaged, the servo motor A in the bracket drives the support rod to rotate, and then the gear outside the support rod meshes with the external symmetrical toothed plate to move, so that the two sets of toothed plates drive the drive frame A and the drive frame B to move respectively, and then the drive frame A moves up and the drive frame B moves down. The bottom structure of the drive frame B is the same as the bottom structure of the drive frame A, which facilitates the replacement of the cutter and improves the cutting efficiency of PC sheet.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To improve the slitting efficiency of PC sheets, as one embodiment of this utility model, such as... Figures 1 to 5 As shown, the PC sheet slitting device of this utility model includes an operating table 3. A placement rack 4 for placing PC sheets is slidably connected to one side of the operating table 3. A fixing frame 1 is welded to the outside of the operating table 3, and a drive cylinder 24 is bolted inside the fixing frame 1. A bracket 5 is bolted to the power output end of the drive cylinder 24. A servo motor A9 for providing power is bolted inside the bracket 5, and a support rod 8 is keyed to the power output end of the servo motor A9. A gear 7 is splined to the outside of the support rod 8. The bracket 5 is symmetrically slidably connected to drive frame A2 and drive frame B6. Both drive frame A2 and drive frame B6 have toothed plates 11 welded to their inner sides to mesh with gear 7. Both drive frame A2 and drive frame B6 have cutters 13 for cutting PC sheets screwed to their inner sides. Both drive frame A2 and drive frame B6 have positioning plates A14 and positioning plates B15 symmetrically slidably connected inside the drive frame A2. Both positioning plates A14 and positioning plates B15 have springs 16 welded to their ends. Both positioning plates A14 and positioning plates B15 have rubber pads 17 screwed to their outer sides.

[0023] When using PC sheets, the drive cylinder 24 inside the fixed frame 1 drives the bracket 5 to move, and then the bracket 5 drives the drive frame A2 to move, so that the positioning plate A14 and positioning plate B15 at the bottom of the drive frame A2 contact the surface of the PC sheet. Then the spring 16 at the end of the positioning plate A14 and positioning plate B15 is compressed. The elastic force generated by the spring 16 drives the positioning plate A14 and positioning plate B15 to press the PC sheet, so that the cutting part of the PC sheet is fixed. As the positioning plate A14 and positioning plate B15 contract, the cutter 13 on the drive frame A2 contacts the surface of the PC sheet, improving the cutting efficiency of the PC sheet. When the cutter 13 on the drive frame A2 is damaged, the servo motor A9 inside the bracket 5 drives the support rod 8 to rotate, and then the gear 7 outside the support rod 8 meshes with the external symmetrical toothed plate 11 to move, so that the two sets of toothed plates 11 drive the drive frame A2 and the drive frame B6 to move respectively. As a result, the drive frame A2 moves up and the drive frame B6 moves down. The bottom structure of the drive frame B6 is the same as the bottom structure of the drive frame A2, which makes it easy to replace the cutter 13 and improves the cutting efficiency of PC board.

[0024] To adjust the position of the PC board on the placement rack 4, for example, such as Figure 5 As shown, the present invention also includes a servo motor B22 that provides power and is bolted inside the operating table 3, and a threaded screw 21 that is keyed to the power output end of the servo motor B22. A screw block 23 is threadedly connected to the outside of the screw block 21, and the outside of the screw block 23 is welded to the bottom of the placement frame 4.

[0025] When in use, when the position of the PC board on the placement rack 4 needs to be adjusted, the servo motor B22 inside the operating table 3 drives the threaded screw 21 to rotate. The limiting sleeve symmetrically welded to the outside of the threaded block 23 slides outside the limiting rod symmetrically welded inside the operating table 3, so that the threaded block 23 moves axially outside the threaded screw 21. Then the threaded block 23 drives the placement rack 4 to move, which facilitates the adjustment of the position of the PC board on the placement rack 4.

[0026] To secure the PC sheet, for example, such as Figure 4 As shown, this utility model also includes a double-headed cylinder 20 that provides power, which is bolted inside the placement frame 4. The power output end of the double-headed cylinder 20 is symmetrically screwed with support plates A18 and B19 for fixing the PC sheet.

[0027] When in use, after the PC sheet is placed on the placement rack 4, the double-headed cylinder 20 inside the placement rack 4 drives the support plate A18 and support plate B19 to move, and then the support plate A18 and support plate B19 come into contact with the surface of the PC sheet, thereby facilitating the fixing of the PC sheet.

[0028] To improve the stability of the movement of drive frame A2 and drive frame B6, for example, such as Figure 2 and Figure 3 As shown, the present invention also includes symmetrically formed limiting grooves 10 on the surface of the bracket 5, and symmetrically welded limiting blocks 12 on the exterior of the drive frame A2 and the drive frame B6.

[0029] When in use, as drive frame A2 and drive frame B6 move, the limiting blocks 12 symmetrically welded to the outside of drive frame A2 and drive frame B6 slide within the limiting grooves 10 symmetrically opened on the bracket 5, thereby facilitating the limiting of drive frame A2 and drive frame B6 and improving the stability of the movement of drive frame A2 and drive frame B6.

[0030] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model also includes the fact that the input terminals of the double-headed cylinder 20, servo motor B22, servo motor A9 and drive cylinder 24 are all electrically connected to the power supply terminal of an external power source.

[0031] When in use, the electrical equipment works normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0032] In use, the PC sheet is first placed in the placement rack 4. Then, the double-headed cylinder 20 in the placement rack 4, driven by the PLC controller, moves the support plates A18 and B19, causing them to contact the surface of the PC sheet and fix it in place. Next, the servo motor B22 in the operating table 3, driven by the PLC controller, rotates the threaded screw 21. The threaded screw 21 is mounted in the bearing seat of the operating table 3 via a deep groove ball bearing, which is welded to the inner wall of the operating table 3. The symmetrically welded limiting sleeves on the outside of the threaded block 23 slide outside the symmetrically welded limiting rods inside the operating table 3, causing the threaded block 23 to move axially outside the threaded screw 21. The threaded block 23 then moves the placement rack 4, adjusting the position of the PC sheet on the rack 4. Then, the drive cylinder 24 in the fixing frame 1, driven by the PLC controller, moves the support 5. Subsequently, the support 5 moves the drive frame A2, causing the positioning plates A14 and B15 at the bottom of the drive frame A2 to move. Upon contact with the PC sheet surface, the springs 16 at the ends of positioning plates A14 and B15 are compressed. The elastic force generated by the springs 16 causes positioning plates A14 and B15 to press the PC sheet, thus fixing the PC sheet at the cutting point. As positioning plates A14 and B15 contract, the cutter 13 on the drive frame A2 contacts the surface of the PC sheet, performing cutting. When the cutter 13 in the drive frame A2 is damaged, the servo motor A9 in the bracket 5, driven by the PLC controller, rotates the support rod 8. The support rod 8 is installed in the bearing seat of the bracket 5 through a deep groove ball bearing. The bearing seat is welded to the inner wall of the bracket 5. Then, the gear 7 outside the support rod 8 meshes with the external symmetrical toothed plates 11, causing the two sets of toothed plates 11 to drive the drive frame A2 and drive frame B6 to move respectively. Thus, the drive frame A2 moves upward and the drive frame B6 moves downward. The bottom structure of the drive frame B6 is the same as the bottom structure of the drive frame A2, which facilitates the replacement of the cutter 13 and improves the cutting efficiency of the PC sheet.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
