[0019] The attached figure shows a specific embodiment of this utility model.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1 to 6 As shown, this longitudinal cutting structure suitable for thick PVC board production includes two bases 1, which are installed on the production line. Two guide shafts 2 are installed between the two bases 1, and the two guide shafts 2 are distributed vertically. There are also three cutter holders 3, each with two guide holes through which the two guide shafts 2 pass, allowing the guide holders to slide on the two guide shafts 2. Each cutter holder 3 has a threaded hole, and the middle cutter holder 3 also has a through hole. The threaded holes and through holes of the two outer cutter holders 3 are aligned in a straight line. The threaded hole of the middle cutter holder 3 is threadedly connected to a middle upper shaft threaded rod 4, and the two ends of the middle upper shaft threaded rod 4 are mounted on the base 1 by bearings. An upper shaft screw 5 with opposite threads is threadedly connected to the threaded holes on the two outer cutter holders 3, and the upper shaft screw 5 passes through the through hole on the middle cutter holder 3. The rotation of the upper shaft screw 5 can drive the two outer cutter holders 3 to move in opposite directions.

[0023] The two ends of the upper shaft screw 5 are respectively mounted on two bases 1 via bearings.

[0024] Each cutter holder 3 is fixedly equipped with a cylinder 6, or a hydraulic cylinder. The output end of the cylinder 6 faces downward and a motor 7 is fixedly installed. The motor 7 is installed horizontally, that is, the output end of the motor 7 is perpendicular to the direction of travel of the production line. A longitudinal saw 8 is fixedly installed at the output end of the motor 7. The longitudinal saw 8 is circular and has serrations in its circumference. A protective cover 9 is also fitted over the longitudinal saw 8. The lower end of the protective cover 9 is open, and the lower end of the longitudinal saw 8 is exposed from the opening.

[0025] Below each longitudinal saw 8 is a movable plate 10. The movable plate 10 moves synchronously and in the same direction as the longitudinal saw 8 above it. There is a long strip-shaped cutting hole 11 on the movable plate 10. The length direction of the cutting hole 11 is the direction of travel of the production line. When the cylinder 6 is started and extended, the lower end of the longitudinal saw 8 can enter the cutting hole 11.

[0026] A vacuum cleaner 12 is installed on the lower surface of the movable plate 10, with the vacuum cleaner 12 facing the cutting hole 11.

[0027] Two guide rails 13 are fixedly installed between the two bases 1. The two guide rails 13 are arranged in parallel. Two guide grooves 14 are fixedly installed on the lower surface of each movable plate 10. The two guide rails 13 are located in the two guide grooves 14 respectively.

[0028] Below the movable plate 10 is a lower shaft rotating screw 15. The lower shaft rotating screw 15 has the same structure as the upper shaft rotating screw 5, that is, the two ends have threads in opposite directions. Threaded cylinders are installed below the two movable plates 10 on both sides. The lower shaft rotating screw 15 is threadedly connected to the threaded cylinders. The two ends of the lower shaft rotating screw 15 are also mounted on the base 1 through bearings.

[0029] The middle sections of the upper shaft screw 5 and the lower shaft screw 15 are unthreaded.

[0030] The upper shaft screw 5 and the lower shaft screw 15 rotate synchronously through a sprocket and a chain. A hand crank 16 can be installed at one or both ends of the upper shaft screw 5, or at one or both ends of the lower shaft screw 15. Up to four hand cranks can be installed for easy operation.

[0031] Below the upper shaft threaded rod 4 is a lower shaft threaded rod 17. Both ends of the lower shaft threaded rod 17 are mounted on the base 1 via bearings. The lower shaft threaded rod 17 drives the middle movable plate 10 to move. Specifically: To ensure the smooth movement of the middle moving plate 10, an auxiliary plate 18 is installed on the lower surface of the middle moving plate 10. A through hole 19 is opened on the auxiliary plate 18, and another threaded hole is opened. The lower shaft rotating screw 15 passes through the through hole 19, and the middle lower shaft rotating threaded rod 17 is threadedly connected to the aforementioned threaded hole.

[0032] The upper and middle shaft threaded rod 4 and the lower and middle shaft threaded rod 17 rotate synchronously through a sprocket and a chain.

[0033] A hand crank 16 can be installed at one or both ends of the upper shaft threaded rod 4, or at one or both ends of the lower shaft threaded rod 17. Up to four hand cranks 16 can be installed.

[0034] Each tool holder 3 is equipped with a locking device 20, which is a screw. Tightening the screw causes the inner end of the screw to press against the guide shaft 2, thereby fixing the guide shaft 2 and the tool holder 3.

[0035] The usage process is as follows: The distance between the two longitudinal saws 8 can be determined by the hand cranks 16 at both ends of the upper shaft screw 5 and the lower shaft screw 15, so as to determine the width of the cut edge of the PVC board. It can be adjusted on both sides of the production line, which is convenient and quick.

[0036] The position of the slitting saw 8 in the middle can be adjusted by the hand cranks 16 at both ends of the upper and lower shaft threaded rods 4 and 17. This allows for longitudinal cutting of PVC boards, and the width of the two cut PVC boards can be adjusted arbitrarily, either to be the same width or different widths.

[0037] After adjusting the positions of the three longitudinal saws 8, the cylinder 6 can be started to lower the longitudinal saws 8 into the cutting holes 11 below them. The motor 7 can be started to make the longitudinal saws 8 rotate, thus cutting the PVC longitudinally.
